Detailed Description
The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1 to 2, the utility model provides a press pump structure with a waterproof ring, which comprises a pump body 1 extending into the bottle body, a lock bottle cap 2, a lock cover 3, a press head 4, a pump chamber 11, an upper pump rod 5, a lower pump rod 6, a piston 7, a spring 8 and a one-way valve 12, wherein the lock bottle cap 2 is connected on the pump body 1, the lock cover 3 is sleeved on the upper end of the pump body 1, and the pump chamber 11 is arranged on the pump body 1; the upper pump rod 5 is arranged in the pump chamber 11 and is provided with a suction channel 51, the upper end of the upper pump rod 5 is fixedly inserted with the press head 4, the lower end of the upper pump rod 5 is connected with the lower pump rod 6, the lower pump rod 6 is provided with a liquid inlet groove 61 capable of communicating with the suction channel 51, the piston 7 is sleeved at the lower end of the lower pump rod 6, the spring 8 is arranged in a spring 8 accommodating cavity 31 formed between the upper pump rod 5 and the lock cover 3, and the one-way valve 12 is arranged at the lower end of the pump chamber 11; go up and be provided with waterproof construction between pump rod 5 and the locking closure 3, waterproof construction locates the waterproof ring 9 of pump rod 5 for the cover, waterproof ring 9 upper end and last pump rod 5 interference fit.
The working process of the pressing pump structure of the embodiment is as follows: after the press head 4 is pressed downwards for the first time, the spring 8 is compressed, the press head 4 drives the upper pump rod 5 and the lower pump rod 6 to move downwards, the piston 7 presses the gas in the pump chamber 11 into the suction channel 51 from the liquid inlet groove 61 to discharge the gas, and the pump chamber 11 is in a negative pressure state at the moment; after the hand is released, the spring 8 automatically extends to restore the natural state due to the elastic force of the spring 8, the upper pump rod 5 and the lower pump rod 6 move upwards under the elastic force of the spring 8, the pressure in the pump chamber 11 is smaller than the pressure in the bottle body, at the moment, the one-way valve 12 is opened, the emulsion in the bottle enters the pump chamber 11, and when the air pressure in the pump chamber 11 is equal to the air pressure in the bottle, the one-way valve 12 is closed; when the plunger 7 is moved downward to press the pump chamber 11 by pressing the plunger 4 again, the emulsion enters the suction passage 51 from the liquid inlet groove 61 and then flows out of the plunger 4. The push head 4 is repeatedly pressed in this way, so that the emulsion in the bottle can be discharged for use, and the operation is simple.
In the whole pressing and using process, the upper end of the waterproof ring 9 is always in interference fit with the upper pump rod 5, so that external pollutants such as water or dust are effectively prevented from entering the pump body 1, the risk that the internal liquid is polluted and goes bad is reduced, the sealing performance of the emulsion pump is improved, and the subsequent using effect is ensured. In addition, because the spring 8 sets up in the spring that forms between last pump rod 5 and locking closure 3 holds the chamber 31, realized that the spring 8 is external, can avoid the direct emulsion contact with in the pump body 1 of spring 8, avoid the contaminated problem of emulsion.
In this example, the waterproof ring 9 is a thin-walled structure, and has a simple structure, convenient production and high strength.
As shown in fig. 4 and 5, an air inlet gap 32 is provided between the waterproof ring 9 and the locking cover 3, an air inlet groove 33 communicated with the accommodating cavity 31 of the spring 8 is provided at the upper end of the locking cover 3, the air inlet gap 32 is communicated with the air inlet groove 33 to form an air inlet channel for external air to enter the accommodating cavity 31 of the spring 8, the air in the accommodating cavity 31 of the spring 8 can be supplemented through the air inlet channel in the using process, and the problem of bottle collapse caused by the fact that the air cannot be supplemented into the bottle in time due to the reduced amount of the material in the using process of a user is prevented.
As shown in fig. 1 and 2, the lower end of the pump chamber 11 is tapered, in this embodiment, the check valve 12 is a pump ball disposed at the lower end of the pump chamber 11, and an elastic stopper 13 capable of preventing the pump ball from being disengaged is disposed in the pump chamber 11 and above the pump ball.
The above is only the preferred embodiment of the present invention, as long as the technical solution of the purpose of the present invention is realized by the substantially same means, all belong to the protection scope of the present invention.
