Take you to know about lotion pumps every day

In the previous issue, I explained to you how to choose a suitable lotion pump. I believe that everyone has already chosen a lotion pump that suits you. Then this issue will briefly explain the working principle of the lotion pump. The lotion pump is also called the press-type lotion pump. It is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle by pressing and fill the bottle with the outside air.The working principle of the lotion pump is mainly divided into 5 knowledge points, one is the first pressing, the second is reciprocating pressing, the third is absorbing liquid, the fourth is storing liquid, and the fifth is discharging liquid. After understanding these 5 knowledge points, you will understand the working process of the lotion pump. 1. The first press That is, when the pump head is pressed for the first time, the pump head drives the piston head to compress the spring through the connected connecting rod; during the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the cylinder, prompting the piston to open the liquid outlet of the piston head; When sliding down, the air in the cylinder is discharged through the liquid outlet hole of the piston head that has been opened. 2. Repeated pressing Press several times to expel all the air in the cylinder. 3. Suction up the liquid Press the pump head by hand, pass the connecting rod, piston head, and piston, and compress the spring together to discharge the air in the cylinder, then release the pump head, the spring will move back (up) due to the loss of pressure, and the piston will also rub against the inner wall of the cylinder. Move downwards to close the liquid outlet hole of the piston head. At this time, the liquid storage chamber in the cylinder forms a vacuum liquid suction state, and the ball valve is sucked up, and the liquid in the bottle is sucked into the liquid storage chamber of the cylinder through the suction pipe. 4. Storage of liquids Press the pump head several times, and store the liquid in the cylinder through multiple suctions until the liquid is stored full. 5. Out of liquid When the liquid in the liquid storage chamber of the cylinder is full, press the pump head again and the liquid will be sprayed out directly from the nozzle through the liquid outlet hole. The working principle of the lotion pump is over for everyone.Thank you for watching. We will conduct more detailed science popularization for the pump head in the future. We welcome more people to pay attention to our company, ZHUHAI BAOLI FOAM SPRAY PUMP CO.,LTD.

How to choose the right lotion?

Today I will share with you how to choose a lotion pump that suits your bottle.   1. First determine the type of lotion pump. Currently, the popular types of lotion pumps on the market include internal spring lotion pumps, external spring lotion pumps, and all-plastic pumps. Innerspring lotion pumps are the least expensive of the three and are the most widely available.However,the pumped liquid will pass through the internal metal spring, and each pump head has basically experienced a year from production to consumer use. After repeated pressing and use, if the spring material is not good, it will rust and affect the liquid in the bottle.Therefore, for those who need high-end daily necessities or cosmetics, it is recommended to use an external spring lotion pump.The advantage of the external spring lotion pump is that the spring is installed outside the liquid channel. This design eliminates the problem that the metal spring will contaminate the liquid.But they are 30% to 50% more expensive than innerspring lotion pumps.There is also an all-plastic pump, which is an all-plastic material just by the name.So what are the advantages of this pump head? The first is to reduce weight and facilitate transportation. The second is to reduce the use of metals and protect the environment. The third is that it can be used in high-precision industries such as medical care or maternal and child products.However, there are still some problems with this product at present, such as unstable price and bad pressing feel. With the development, it is expected to replace the traditional lotion pump in the future. 2. After determining the type of lotion pump to buy, I will classify it from the bottle cap specifications, mainly relying on the inner diameter of the bottle cap (the inner diameter is the diameter of the innermost end of the pump head bottle cap) or the height of the large circle thread in the bottle cap.So how to determine the size? First of all, it is necessary to determine the diameter of the bottle mouth. Professional caliper tools are required for self-measurement. Non-professionals may have errors in the measurement, which will cause the bottle to not match the pump head. Usually when this happens, we suggest sending the bottle to the pump head manufacturer for testing. After finalizing the specifications of the pump head, proceed to the next step of mass production. Finally, thank you for your patience to watch. We will conduct more detailed science on the pump head in the future. Please pay attention to our official website.

Let's analyze why the lotion pump can't bounce back when it is tapped and then pressed

Let's analyze why the lotion pump can't bounce back when it is tapped and then pressed. In order to prevent this kind of situation from happening, in the production process, we must first check whether the length of the torsion spring is standard, and the length of the torsion spring is worth a thousand miles. The effect of the length on the piston rod cannot be ignored. If it is too short, it will lead to the return of the piston rod If it is not in place, it will immediately cause the button to not rebound or the rebound force will be relatively slow after the head is pressed down. Next, check whether the thickness of the piston rod is suitable for you. During the movement of the piston rod, any slight gap will cause shortness of breath, and you will not be able to press the head against the feed body. Because plastic has the characteristics of thermal expansion and cold contraction, a normal piston rod is very important to ensure the quality of the lotion pump. Let's analyze ourselves together. Due to the extensibility characteristics of plastics, if the operation is wrong during the injection molding process, the injection is not enough, and a thin layer of itself will be cut off, resulting in uneven inner cavity. It is inevitable that there will be gaps, resulting in failure to feed. The basic principle of lotion pump,when using, we first press lightly to discharge the air in the liquid storage chamber (that is, the plastic hose that can absorb shampoo). When the air is exhausted, press the pump head again, because after letting go, the twist in the impeller of the water pump will The spring should return to normal, so that a vacuum pump will be generated in the liquid storage chamber, resulting in negative pressure. At this time, the gas pressure in the container is consistent with the atmospheric pressure. At this time, because of the pressure difference, the air will press the liquid around the mouth of the liquid storage chamber into the liquid storage chamber, giving the impression that the liquid is sucked up by the impeller of the water pump. The plastic pump head of skin care products should not be used too frequently. Since the resilience of the spring is relatively limited, each use must be within the elastic range of the spring and cannot be used forcibly. This is the same as the limit of a person. After that, it will collapse. On average, each pump impeller tap should not exceed 10 times, and the interval should not be less than 10 seconds. There needs to be enough time to make it bounce back. The torsion spring embedded in the water pump impeller of skin care products should not be too long. Naturally too short is definitely not acceptable. The selection of the general cable diameter also plays a key role. Generally speaking, the torsion spring of the water pump impeller of general skin care products has 13 and a half turns. It is more effective, so that both the resilience and the pressing pressure are just within a certain range. Lotion pumps can be customized in different colors according to customer requirements. In your daily life, you often use push-type hand sanitizer plastic bottles and shampoo plastic bottles. Then there will be plastic bottles with a pump head, which is very convenient to use and can also control the amount of use. Material: Plastic pp Color tone: Different colors can be customized according to customer requirements Main application: Widely used in skin care products, high-end cosmetics, day cream, paste, moisturizing lotion, toner, etc. Product advantages: Beautiful appearance design, exquisite and easy to use, economical and practical, bright colors.

33 What is the tooth lotion pump like?

With the gradual improvement of people's living standards, the use of many household items has become more and more convenient, including the application of 33 tooth emulsion pumps. 33 Dental lotion pump, also known as push-type lotion pump, is a tool that uses the principle of atmospheric pressure balance to pop the lotion in the bottle by pressing it, and at the same time add the outside atmosphere into the bottle. Next, let's talk about what the 33 tooth lotion pump is like? 1.33 Dental lotion pumps can be divided into plunger type and screw type. Function can be divided into spray, foundation cream, lotion pump, aerosol valve, vacuum bottle. 2.33 The size of the tooth lotion pump is determined by the diameter of the bottle. The spray size is 12.5mm-24mm, and the water output is 0.1ml/-0.2ml/time. Generally used for packaging perfume, jelly water and other products. The length of the nozzle of the same caliber can be determined according to the height of the bottle. 3.33 Tooth lotion pump pump head specification range 16ml-38ml, water output 0.28ml/-3.1ml/time. Generally used in face creams and detergents. 4. Special dispensers, such as foam pump heads and manual button nozzles. The emulsion pump head is an airless hand pump head. It does not need to be inflated to produce foam, only light pressure can produce quantitative high-quality foam. Usually comes with a special bottle. Manual button nozzles are often used for products such as detergents. 5. The composition of the distributor is relatively complicated, generally including: dust cover, chuck, chuck rod, gasket, piston, spring, valve, bottle cap, pump body, straw and valve ball (steel ball and glass ball). Bottle caps and dust covers can be colored, plated, and anodized. Since a set of lotion pump heads involves many molds, the order quantity is large, the smaller order quantity is 10000-20000, and the delivery time is 15-20 days after sample confirmation. White and generic are often in stock. 6. The lotion bottle is usually cylindrical, with a specification of 15ml-50ml, and each bottle is 100ml. The overall capacity is small, relying on the principle of atmospheric pressure, it can avoid the pollution caused by cosmetics in use. Thermos bottles are made of anodized aluminum, plastic plating, and colored plastic, and are more expensive than other common containers and don't require as much in common quantities. When purchasing products containing 33 tooth lotion pumps, you must know that during the pressing process, it needs to be connected to its head, and the piston is driven by the compression spring for use. In the process of compressing the spring, the outer wall of the emulsion pump piston often makes the piston fully open through the friction of the inner cavity wall, and the liquid appears in the discharge hole of the piston head. As the piston moves down, the internal air will be expelled from the piston head. We can completely discharge the air in the chamber by pressing several times, then press the head with hands, and then discharge the air in the chamber through the action of the piston connecting rod and the compression spring. At this time, loosen the pressure head of the emulsion pump by hand, and the spring will lose pressure and move down again. At this time, the piston moves down by rubbing the inner wall to close the discharge hole.

33 How much do you know about the tooth lotion pump? Why doesn't it rebound after pressing?

33 How much do you know about the tooth lotion pump? Why doesn't it rebound after pressing? When in use, we first expel the air in the liquid storage chamber (that is, the plastic tube that can absorb lotion) by pressing. When the air is out, press the pump head down again. Since the spring in the pump head will return to its original shape after being released, a vacuum will be formed in the liquid storage chamber to generate negative pressure. At this time, the pressure in the container is consistent with the atmospheric pressure, which will cause the pressure in the liquid storage cavity to be low and the pressure in the container to be high. The basic functions of the 33 tooth lotion pump are: 1. Sealing function. It is believed that every consumer is unwilling to accept products whose contents leak from the surface of the bottle. After the pump and bottle are filled and packaged, the sealing function is one of the important requirements to ensure the storage and transportation of the bottled product. With the development of electronic technology and the improvement of automation level, there is a standard configuration in the production process of the fully automatic inflatable 33 tooth emulsion pump. As for the parameters in the test method, such as vacuum degree, time, pressure, air pressure, etc., each company has different control parameters according to customer requirements, so I will not repeat them here. 2. The pumping function of the 33 tooth lotion pump. The characteristic of the 33 tooth lotion pump is that it can pump out the same volume of liquid for consumers every time, so the pumping function is also one of the important requirements. In the manufacturer, the intuitive way to verify this function is: open the pressure head of the 33 tooth lotion pump, then press the pressure head down to the end of the stroke, block the liquid inlet of the cylinder shell with the fingers of the other hand, and loosen the pressure head Make it rebound naturally, the skin on the surface of the finger will feel sucked (commonly known as "sucking"), and even the emulsion pump is hung upside down on the finger. This is one of the main judgment methods for the manufacturer to confirm whether the pumping function is intact. Why can't the 33 tooth lotion rebound after pumping? In order to avoid this situation, in the production process, first check whether the length of the spring is standardized. The difference is thousands of miles, and the effect of length on the piston cannot be ignored. If it is too short, the return stroke of the piston will not be in place, which will directly cause the pressure head to fail or rebound slowly. Second, check whether the thickness of the piston is suitable for the body. During the movement of the piston, any gap will cause weak suction, and the pressure head will not be able to press the material. Because plastics expand with heat and contract with cold, ordinary pistons are crucial to the quality of emulsion pumps. Then. Let's analyze the bottle body of the 33 tooth lotion pump. In view of the flexibility of the plastic, if the plastic is not handled properly during injection molding, the thin layer of the body will be cut off due to insufficient injection, resulting in uneven inner walls, which will inevitably leave gaps during the stamping process of the piston, resulting in failure to discharge. We are the manufacturer of 33 tooth lotion pump, if you want to know more about this, please contact us. We can introduce it to you from different aspects.

The following explains what a lotion pump head is and precautions for use

The following explains what a lotion pump head is and precautions for use. 1. Regulators are divided into two categories: integrated and spiral. In terms of functions, it is divided into sprayers, powder creams, emulsion pumps, aerosol valves, and vacuum bottles. 2. The specifications of the impeller of the pump are set according to the specifications of the bottle of supporting facilities. The specification of the sprayer is 12.5mm-24mm, and the water flow is 0.1ml/time-0.2ml/time. It is mainly used in the packaging of eau de toilette and suspected glue products. The same nozzle length can be determined according to the relative height of the bottle body. 3. The head size of the emulsion pump is 16ml~38ml, and the water flow is 0.28ml/time~3.1ml/time, which is generally used for day cream and daily chemical products. 4. Special-purpose regulators, such as foam pump heads and manual button nozzles. The foam pump head is a non-filling pneumatic manual pump head, which does not use gas to form foam, and only needs to be lightly pressed to produce high quantitative Quality foam. General configuration special bottle. Manual button nozzles are generally used for detergents and other products. 5. The composition of the regulator is complex, generally including: dust cover, tension, pressure rod, gasket, piston rod, torsion spring, gate valve, bottle stopper, pump casing, suction pipe and valve ball (including bearing steel ball and glass marbles). Bottle stoppers and sealing caps are capable of coloring, electroplating processes, and covering photocatalytic aluminum rings. 6. Vacuum bottles are generally cylindrical, with a specification of 15ml-50ml, about 100ml, and a relatively small overall volume. They use the basic principle of atmospheric pressure to avoid environmental pollution caused by skin care products during use. Vacuum bottles include electrolytic aluminum plants, plastic plating and colored plate plastics. What should I pay attention to when using the lotion pump head? The lotion pump head is also called the working pressure lotion pump. It uses the principle of air balance to pump out the raw material liquid in the bottle, and fills the outside air to the liquid regulator in the bottle. The important performance parameters of the lotion pump head: pneumatic frequency, pump luminosity, diastolic pressure, pressure bucket opening torque, rebound rate, water seepage index value, etc. Lotion pump head regulators are divided into sanitary ware and screws, and functionally divided into sprayers, powder creams, lotion pumps, air atomizing valves, and vacuum bottles. Some basic common sense about lotion pump. The lotion pump uses the principle of air balance to pump out the raw material liquid in the bottle according to the side pressure, and fills the external air into the liquid regulator in the bottle. The important performance parameters of the lotion pump: standard air pressure frequency, pump displacement, low Working pressure, nozzle opening torque, rebound force rate, water inlet flow index value, etc. The size of the pump head is determined by the specification that matches the bottle body. The specification and model of the sprayer is 12.5mm-24mm, and the water flow rate is 0.1ml/time-0.2ml/time. It is generally used in the packaging design of eau de toilette and glue, and the specifications are the same , the work transfer length needs to be determined by the height of the bottle.
