Push-type elastic balloon pump

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, ...

AI Technical Summary

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
