Fig. 1 is a schematic structural diagram for explaining an embodiment of the present invention;

in the figure, 1 is a pump body, 2 is a valve rod, 3 is a piston, 4 is a material inlet, 5 is a one-way valve plate, 6 is a valve needle, 7 is a plastic spring, 8 is a connecting seat, and 9 is an annular edge.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is a press type liquid pump, including a pump body 1, a valve rod 2 is installed in the pump body 1, a piston 3 is further installed at the end of the valve rod 2, correspondingly, the piston 3 needs to be in close contact with the inner wall of the pump body 1, so as to ensure that a negative pressure can be formed inside the pump body, a material inlet 4 is further installed at the lower portion of the pump body 1, and a check valve plate 5 is installed on the material inlet 4, the check valve plate 5 is shown in the figure, and can pass from bottom to top, and is sealed from top to bottom, so that the material can enter the interior of the valve body 1 from the material inlet 4 under the negative pressure formed by the piston 3, more importantly, a valve needle 6 is also installed on the piston 3, the valve needle 6 is fixed at the end of the rod of the piston 3, a small part of air above and below the piston 3 can be circulated through the valve needle 6, thereby improving the accuracy of the material guided out by the pressing pump; on the other hand, need add a plastic spring 7 between the upper end of valve rod 2 and the pump body 1 upper end, plastic spring 7's both ends are contradicted respectively in valve rod 2 upper end and the pump body 1 upper end, can make valve rod 2 pressed the back at every turn through aforementioned plastic spring 7, all can reset under plastic spring 7's elastic force effect, are convenient for press once more. Preferably, in order to facilitate discharging, a material outlet (not shown in the figure) may be further disposed on the side surface of the pump body 1, and then a one-way valve plate is also disposed on the material outlet, the one-way valve plate is opposite to the one-way valve plate on the material inlet 4, specifically, the one-way valve plate can pass from inside to outside, and is sealed from outside to inside, so as to ensure that the material entering the pump body 1 from the material inlet 4 can be directly discharged from the material outlet.

In this embodiment, through installing needle 6 on piston 3 for atmospheric pressure in the pump body 1 can be controlled, thereby promote the accuracy nature of every pump material, and add plastic spring 7 between valve rod 2 and the pump body 1, can in time kick-back reset after valve rod 2 is pushed down, and the state of plastics material is stable, can not produce the corrosion, thereby be difficult for causing the pollution to the material, and make the pump body production also environmental protection more.

Still referring to fig. 1, preferably, in order to facilitate the pump body 1 to be mounted on the bottle for use, as an improvement of the above embodiment, a connecting seat 8 may be further added at the upper end of the pump body 1, and the connecting seat 8 and the valve stem 2 are also made of plastic, so as to facilitate the integrity of the pump body structure and the mounting of the liquid pump on the bottle; further, in this embodiment, in order to facilitate installation of the plastic spring 7, an annular edge 9 may be further added to the upper end of the valve rod 2, and the end of the plastic spring 7 abuts against the lower portion of the annular edge 9, so as to facilitate the effectiveness of resilience force of the plastic spring 7, and enable the valve rod 2 to effectively reset each time.

Referring to fig. 1, in practical use, the above preferred embodiment of the present invention is shown in fig. 1, fig. 1 is a longitudinal sectional view of a liquid pump, in which the top of a valve stem 2 is pressed, so that the valve stem 2 moves a piston 3 downward, thereby compressing the inner cavity of the pump body 1, if the inner cavity has materials at the moment, the materials are discharged along with the material outlet in the compression process, then the upper part of the valve rod 2 is loosened, the valve rod 2 is reset under the action of the plastic spring 7, the valve rod 2 drives the piston 3 to move upwards, negative pressure is formed in the inner cavity of the pump body 1, materials are sucked into the inner cavity of the pump body 1 through the material inlet by the negative pressure, then the materials can be discharged along with the material outlet by pressing the valve rod 2 again, and the circulation is realized, in the process, the amount of the materials sucked and discharged by each pump can be adjusted by adjusting the valve needle 6 on the piston 3, and the materials can be accurately led out.
