Emulsion pump head utility model content

The purpose of this utility model is to supply the emulsion pump head with a simple layout, to prevent the introduction of harmful substances during the operation process, the use is cleaner, the service life is long, it can be used repeatedly, without pollution, and can be easily recovered again.

In order to achieve the intent, the technical plan selected for the present invention is an emulsion pump head, which includes a connecting rod with a head cap, the connecting rod is connected to the pump body through a gland, and a large cover is sleeved on the outside of the gland. A tension spring sleeved on the outer side of the connecting rod between the head cap and the pressure cover is a plastic tension spring.

Preferably, the pump body is provided with a piston seat, and the connecting rod is connected to a side of the pump body with a piston matched with the piston seat. Such a layout can improve the power of the emulsion pump head during operation, making the pressure greater, and the liquid is satisfied every time it is pressed.

Preferably, the inside of the large cover is also provided with threads. This layout allows the large cap to be removed for cleaning and repairing, and can be applied to different bottles.

Preferably, the bottom end of the pump body is provided with a sealing sheet. The sealing sheet seals the pump body and improves the efficiency when used:

Because the technical plan is selected, the emulsion pump head of the present invention passes through the plastic tension spring sleeved on the outside of the connecting rod between the head cap and the gland to prevent the plastic tension spring and the emulsion liquid from touching. Ensure the cleanliness of the emulsion pump head. And once damaged, it is easy to repair and improve the service life of the product. The plastic spring is not only consistent with the bottle body, it is also cheap and easy to replace.

Emulsion pump head, including a connecting rod 2 with a head cap 1, the connecting rod 2 is connected to the pump body 8 through a gland 4, a large cap 6 is sleeved on the outside of the gland 4, the head cap 1 and the pressure A plastic spring 3 is sleeved on the outside of the connecting rod 2 between the covers 4. The pump body 8 is provided with a piston seat 7, and the connecting rod 2 is connected to the side of the pump body 8 and a piston 5 matched with the piston seat 7 is fixed. The inside of the large cover 6 is also provided with threads 10. A sealing sheet 9 is provided at the bottom end of the pump body 8.

The operation is the same as the existing emulsion pump head, just press down the head cap 1, the head cap 1 moves the connecting rod 2 to advance the gland 4, so that the air in the pump body 8 is compressed, the piston 5 and the piston seat 7 mutually effect the emulsion From the beginning, it is output from the headgear 1 through the connecting rod 2, and the headgear 1 returns to its original position at the moment under the effect of the plastic tension spring 3. In the whole process, in addition to the reset effect, the plastic spring 3 also prevents the outside from touching the lotion, ensuring cleanliness and hygiene.
