Problems solved by technology

Usually the lotion pump has been connected in the bottle cap, and the introduction tube, pressure rod and nozzle are configured to supply the market. It has been widely used for many years. The rust of the spring and the reliability of its action have been solved. Its biggest shortcoming is Inefficiency, whether in terms of material utilization or power use
[0008] The total height of the pump cylinder is 55 mm for the 3ml lotion pump purchased from the market. The return spring accounts for about 71.8% of the height of the pump cylinder section, accounting for most of the height of the pump body, while the piston accounts for about 18.2% of the height of the pump cylinder section, and the rest is The connecting section on the upper part of the piston; while the stroke of the piston is 15 mm, which only accounts for 27.3% of the height of the pump cylinder section, which shows that the utilization rate of the stroke for pumping liquid is very low

Embodiment 1

[0043] like figure 1 As shown, the push-type elastic bag pump includes a pump body 3 and an elastic bag 4 . The center of the pump body 3 has an inlet port 3.2, which is the inlet channel of the pump, and an inlet check valve 2 is installed in it; the side wall 3.3 of the pump body 3 has an outlet port 3.3, which is the outlet channel of the pump, and an outlet is installed in the outlet port 3.3. One-way valve 6; pump body 3 upper opening has junction 3.1, and elastic capsule 4 has outer edge 4.1 that can cooperate with the junction 3.1 of caulking into pump body 3, and forms sealing, has just constituted push-type elastic capsule pump.

Embodiment 2

[0045] This embodiment is a specific application structure based on the first embodiment, such as figure 2As shown, the positional relationship between the push-type elastic bag pump, the pressure rod 8 and the bottle cap 7 is the same as that of the conventional piston pump, and the push-type elastic bag pump replaces the nozzle. The lower end of the inlet port 3.2 of the pump body 3 is connected with the pressure rod 8, and the other end of the pressure rod 8 is connected with the bottle cap 7 interface 7.3 and then connected with the guide tube 1, which is located in the bottle cap 7 and extends into the bottle; the nozzle 5 of the spray head and The outlet port 3.3 of the pump body 3 is integrated, the elastic bag 4 becomes the pressing surface, and the liquid can flow out from the nozzle 5, which is completely the same as the nozzle. The ring gap in the bottle cap 7 has a sealing ring 12, and the ring gap has a balance aperture 7.6, such as Figure 10 Shown, seal ring 1...

Embodiment 3

[0048] This embodiment is a specific application structure based on the first embodiment, such as image 3 As shown, the push-type elastic bag pump is configured on the bottle cap 7 . The bottom of the pump body 3 is a part of the bottle cap 7, that is, the bottom of the pump body 3 is integrated with the bottle cap 7, the inlet port 3.2 in the center of the pump body 3 is in the center of the bottle cap 7, and the lower end of the inlet port 3.2 is connected to the guide tube 1 , the guide tube 1 is located in the bottle cap 7 and extends into the bottle; the nozzle 5 and the outlet port 3.3 of the pump body 3 are integrated; There are balance holes 7.6, such as Figure 10 Shown, seal ring 12 adds knife edge, just forms one-way hinge 12.1, and the one-way hinge 12.1 of seal ring 12 is right against balance aperture 7.6 center.

Abstract

The invention relates to a push-type elastic balloon pump, which comprises an elastic balloon, a pump body, a pressure lever, an inlet check valve, an outlet check valve, a nozzle, a bottle cap and the like, wherein the lower edge of the elastic balloon is impacted into the pump body to form seal. The elastic balloon is pushed with a hand to deform, the intracavity pressure of the balloon rises, and the inlet check valve and the outlet check valve are opened and closed to discharge liquid through the nozzle; the push is stopped, the elastic balloon is reset to lower the intracavity pressure of the balloon, and the inlet check valve and the outlet check valve are opened and closed to suck the liquid through a suction pipe. A piston and a reset spring of an original piston pump are replaced by the elastic balloon functionally, so that the height of a pump cylinder is greatly reduced. The friction problem brought by dynamic seal of the piston of the original piston pump is also solved by the push-type elastic balloon pump, and therefore, labor is saved. The push-type elastic balloon pump with double cavities can be put in a comb, and the comb becomes a hair-coloring comb by configuring comb teeth, a comb handle and two bags of hair-coloring liquid. The push-type elastic balloon pump is simple in structure and low in cost, is convenient for various aesthetic modeling and is in favor of beautifying life.

Description

[0001] technical field [0002] The invention belongs to daily necessities, and pumps out water or emulsion-like cleansing and beautifying products in a packaging bottle by pressing with hands. [0003] Background technique [0004] Existing bath pumps or lotion pumps are named according to their purposes or liquid forms, and structurally belong to reciprocating piston pumps. [0005] Chinese invention patent CN102452524A "A Airbag Lotion Pump" proposes the use of plastic elastic airbags for conventional lotion pumps to solve the problem of spring rust and the reliability of its action, and can cancel the pump body and piston of the piston pump. The following questions can be raised from the instructions and drawings: 1. How to prevent the plastic elastic airbag from shaking or tilting when it is stressed? 2. Especially how to release the plastic elastic airbag from the mold core during manufacture? Because generally the plastic injection molded parts are straight tubes, ...
