With the improvement of living standards, people always need to use a variety of beauty and skin care products, and they also need to encounter many bottles and cans. However, if it is poured directly from the bottle mouth every time, it is not only unhygienic, and it is difficult to control the output volume each time, which will cause waste. Therefore, in the prior art, the lotion pump head is used for shampoo, shower gel, and hand sanitizer. The pump head is more clean and hygienic, preventing interspersed infection, and it is sure to be popular among consumers. However, the emulsion pump head in the prior art uses a metal tension spring inside, which may cause chemical reactions after long-term use. Not only does the tension spring simply age, but also toxic substances will enter the emulsion and cause pollution, which will make the emulsion pump head life-span. No guarantee. In addition, the connecting rod between the head cap and the gland of the lotion pump head cannot be maintained, so the dust etc. are simply pressed into the lotion. These questions have never been dealt with, and the result is that the service life of the lotion pump head is short, and it is difficult to repeatedly use it for a long time.
The utility model content of the lotion pump head
The intention of the present utility model is to supply the emulsion pump head, with a simple layout, to prevent harmful substances from being brought in during use, to be cleaner in use, to have a long service life, to be reusable, not to pollute, and to be easily recovered again.
In order to achieve the stated intention, the technical plan selected by the present utility model is a lotion pump head, which includes an adapter rod with a head cap. The adapter rod passes through the gland and is connected to the pump body. A large cover is sleeved on the outside of the gland. A plastic spring is sleeved on the outer side of the connecting rod between the head cap and the gland.
Preferably, a piston seat is provided in the pump body, and a piston matching the piston seat is fixed on the side of the connecting rod that connects to the pump body. Such a layout can improve the power of the emulsion pump head during operation, and make the pressure stronger, and the liquid output is satisfied every time the pressure is reduced.
Preferably, a thread is also provided on the inside of the large cover. This layout allows the large cover to be removed for cleaning and repair, and it can be applied to different bottles.
Preferably, a sealing sheet is provided at the bottom end of the pump body. The sealing sheet seals the pump body to improve the efficiency of use:
Because of the selection of the technical plan, the lotion pump head of the present invention passes through the plastic spring that is sleeved on the outside of the connecting rod between the head cap and the gland to prevent the plastic spring and the lotion liquid from being touched. Ensure the cleanliness of the lotion pump head. Moreover, it is easy to repair once damaged, which improves the service life of the product. The plastic spring is not only consistent with the bottle body, but also inexpensive and easy to replace.
The lotion pump head includes an adapter rod 2 with a head cap 1. The adapter rod 2 passes through a gland 4 and is connected to the pump body 8. A large cap 6 is sleeved on the outside of the gland 4, and the head cap 1 and the pressure A plastic tension 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 pump body 8, and a piston 5 matching the piston seat 7 is fixed on the side. The inner side of the large cover 6 is also provided with a thread 10. The bottom end of the pump body 8 is provided with a sealing sheet 9.
The operation is the same as the existing lotion pump head. It only needs to press down the head cap 1, and the head cap 1 moves the connecting rod 2 to push the gland 4, so that the air in the pump body 8 is compressed, and the piston 5 and the piston seat 7 interact with each other to pump the emulsion. It starts to output from the head cap 1 through the adaptor rod 2. At this moment, the head cap 1 returns to the original position under the effect of the plastic tension spring 3. During the whole process, the plastic spring 3 not only has the resetting effect, but also prevents the outside world and the emulsion from touching, ensuring cleanliness and hygiene.
The above are only detailed implementation examples of the present utility model, but the layout features of the present utility model are not limited to this, any changes or modifications made by those skilled in the field within the scope of the utility model are included in the present utility model Among the new types of patents.
