Lotion Pump Wholesale from china supplier

The lotion pump consists of a pressure head, a gland, a bottle cap, a piston rod, a storage cylinder, a habit, a spring, and two one-way ball valves up and down.When using it for the first time, the storage cylinder is filled with air, press the pressure head, because the one-way ball valve under the storage cylinder is blocked, the air in the cylinder can only be discharged upwards from the piston rod. When the pressure head is released, the piston rod will be under the action of the spring. Lift up, at the same time, the upper outlet is closed by the one-way ball valve, the air pressure inside the cylinder is lower than that outside the cylinder, the emulsion pushes the lower ball valve open, and is sucked into the storage cylinder, presses down again, discharges more air, rebounds and sucks the emulsion, this process repeats Two times, the air is completely discharged, and the emulsion is squeezed out from the outlet. The above is the whole principle of the emulsion pump. 

Spring external lotion pump, including press head, lock cover, nut, main column, body, piston, sealing cover, glass beads, spherical seal and external spring; the sealing cover is sealed and fixed in the body; the main column passes through the sealing cover The outer spring is elastically stretched between the main column and the upper end of the sealing cover; the bottom of the main column is provided with an annular slot, and the piston is sleeved in the slot of the main column and can move up and down; the body is provided with a ventilation hole , the sealing cover is connected to the position of the ventilation hole of the body, the sealing cover is provided with an air intake control cavity that communicates with the ventilation hole, and the spherical seal is fitted in the air intake control cavity and realizes the opening of the ventilation hole with the change of position or off. Due to the unique design of anti-leakage structure, the performance requirements of anti-leakage products are more effective and reliable, which greatly simplifies the difficulty of mold manufacturing and production process of traditional emulsion pump products, reduces production costs, and improves product yield. 

External Pump Heads: For nozzles and pump heads, everyone should know that it is necessary to have springs inside the product center. The external pump head (i.e. the spring in the center of the nozzle/pump head) is visible on the outside, usually above the pump head core, and this assembly attaches directly to the nozzle/pump head cover. The advantage of the external pump head is that it does not directly touch the liquid in the bottle, which is relatively hygienic. The external pump head also avoids rusting of the individual springs, which can affect the quality of the product in the bottle. In addition, the power of the external pump head is greater than that of the built-in pump head. Therefore, the external pump head is usually used at a higher rate, and the pump head is suitable for more viscous liquids, such as emulsion liquids. 

The role of the external pump head 

1. Applicable products: granular liquid, sand-like liquid, etc. 

2. Pumping dose: 4.0+0.4g. 

3. The external pump head only needs to be pressed 3-4 times for the first pump, and then it can be pressed out. 

4. The glass ball valve is resistant to acid and alkali solutions. 

5. Non-toxic pump, in line with international standards. 

6. A variety of colors are available for color matching. 

7. Quality description: After matching with the bottle filled with water, prevent the liquid from leaking. Good air tightness, uniform spray volume, strong corrosion resistance and good exhaust function. The external pump heads produced by Jody Technology meet quality standards for safety. The spray amount is even and the effect is good. 

Some external pump heads will design a plastic buckle between the liquid outlet and the lower round cover at the beginning, which is used for fixing and preventing liquid leakage caused by the rotation of the pump head during transportation. At this point, just remove the plastic buckle and rotate the pump head. 

If the external pump head cannot bounce, there may be a problem with the spring in the pressing pump. At this time, the bottle cap can be unscrewed, and the tightness of the spring can be adjusted to make the pressing pump of the external pump head bounce again. You can also use tools such as hand or vise to twist and press the position below the pump until there is a clicking sound, or it can rebound again. The number of turns is not enough, turn it a few more times, or remove it to see if it is stuck somewhere. 

Internal Pump Head: In contrast to the external pump head, the internal pump head (i.e. the spring located in the center of the spray/pump head) is built in and generally not visible. It is usually located in the center of the pump head body. The internal spring can directly touch the liquid. The pressure channel is slightly smaller than the outer channel and is generally more suitable for essential oils, perfumes and skin creams.
