Abstract
A toy inflator pump comprises an air tap, a cylinder and a hand grip. The joint between the air tap and the cylinder composes a unilateral ball valve. The cavity of the cylinder is provided with an inflation piston device and a sealing end-cap is positioned on the cylinder. The inflation piston device is composed of an inflation piston and a piston connection rod, wherein, the piston comprises an upper piston body and a lower piston body. The upper and the lower piston body are fixed via a connection element and a sealing ring is arranged between the two. The sealing ring closely matches with the inner wall of the cylinder and moves between the upper and the lower body of the piston. One end of the piston connection rod is connected with the lower piston body and the other end is connected with the handle. A piston limiting spring is arranged on the connection rod. The utility model has simple structure, small volume, lightly and handy operation and is also convenient to carry.
Description
Affiliated technical field:
The utility model relates to a kind of aerating device, especially a kind of convenient toy inflator pump that uses that is easy to carry.
Background technology:
A kind of need of Chu Shouing charge into the inflation type toy product that just can manifest original shape behind the gas in the market, for example: children's lifebuoy, the little sofa of air cushion type, inflation class toy, inflation class doll, the balloon or the like of playing miscellaneous.After above-mentioned toy product businessman or point of sale are disposable top off, the consumer buys and goes home, but when use and the certain hour of playing after, the said goods needs make-up gas, and market does not have corresponding supporting inflator pump to sell, at this moment children's father and mother or the adult in the family help to solve often will to solve the inflation problem, adopt manual inflation's mode, directly blow in the inflatable substrate body cavity with mouth, such inflation mode had both expended the human body strength, unhygienic again, cause easily also that illness finds its way in by the mouth.
Summary of the invention:
The purpose of this utility model provides a kind of toy inflator pump, solves the problem that occurs in the background technology, has overcome unhygienicly, takes the shortcoming of strength.
The way that the utility model is dealt with problems is achieved through the following technical solutions: a kind of toy inflator pump, comprise valve, inflation cylindrical shell and handle, it is characterized in that valve and the junction surface composition single-direction balls valve body of inflating cylindrical shell, be provided with the inflation piston apparatus in the inflation cylindrical shell cavity, the inflation cylindrical shell is provided with end cover, wherein inflating the inflation piston apparatus that is provided with in the cylindrical shell cavity mainly is made up of inflation piston and piston rod, described inflation piston comprises the upper piston body, the lower piston body, piston body is fixed by connector up and down, be provided with sealing ring between the piston body up and down, sealing circle and cylinder inboard wall closely cooperate, movable between the lower body on the piston, described piston rod one end is connected with the lower piston body, and the other end is connected with handle, and connecting rod is provided with the piston limit spring.Described valve outside is the cone of pagoda shape and is provided with the seam ring that several differ in size, and the bottom end face of valve is a waist through hole, is connected with the inflator pump end of body.
The beneficial effects of the utility model: owing to adopted the piston aerating device, piston is reciprocating under the effect of connecting rod, during inflation because sealing ring and cylindrical shell, lower piston body are line styles seals, when inflation, because of the effect of gas pressure and connecting rod external force more seals sealing ring and cylindrical shell, lower piston body, improved charging efficiency.When inflation finished pumpback, lower piston body and sealing ring broke away from the formation gap, make air inlet fast, and it is light and handy therefore to manipulate process; This small product size is little, and is easy to carry, in use do not need adult help in the family, and children just can inflate toy product.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the valve parts are looked up enlarged drawing among Fig. 1.
