Abstract
The utility model discloses a packing cup and an air pump with the same. A peripheral edge of the packing cup is circular, and a top face of the packing cup is of a circumference structure and provided with a center hole. The packing cup is characterized in that the top face further arches upwards, and the thickness of the packing cup decreases gradually from the center hole to the edge. The air pump has the advantages of good usability, long service life and high working efficiency since a motor drives the packing cup through a pull rod to swing leftwards and rightwards in a chamber and an air inlet valve and an air outlet valve on the chamber are enabled to open and close an air inlet and an air outlet respectively alternately.
Description
Technical field
The utility model belongs to the leather cup in a kind of air pump and air pump, more specifically, thereby be a kind of utilize motor to drive leather cup to stretch by pull bar and compress in switch room, realize gas and replace mobile air pump, relate to the improvement of leather cup structure in this air pump.
Background technique
In prior art, being arranged on respectively in the chamber of body into and out of air valve system of pump, by realizing the sealing into and out of pore and open into and out of air valve, makes gas enter chamber by inlet hole, is then sent from air outlet hole by chamber.
Conventionally, the variation of cavity volume system relies on pull bar stretching or compression leather cup to realize.With reference to Fig. 1, existing leather cup is to be made up of flexible materials such as rubber, and its periphery is ring and plane structure that end face is circumference, and the thickness of leather cup self is all unanimous between the higher and lower levels.Pull bar drives leather cup to do the to-and-fro motion of left and right, they are that pressing plate and the leather cup center hole circular by links to realize, thus and form a working surface, in the time that pull bar swings under electromagnetic force, pull bar just stretches by pressing plate or compresses leather cup and makes its deformation, and then is changing the volume of chamber.But, the actual part contacting with pressing plate on leather cup that occurs in of this deformation, and deformation is from sea level changes camber curved surface, use after certain hour, this part very easily causes mechanical deterioration due to continuous reciprocal stretching or compression, and then affects usability and the working life of pump, simultaneously, the size of this part depends on the size of pressing plate, and it is less than the diameter of leather cup self, directly affects the working efficiency of air pump.
Summary of the invention
The purpose of this utility model is the air pump that a kind of leather cup is provided and contains this leather cup, this leather cup provides a kind of structure, can utilize the upset of himself to change the volume of chamber, and can alleviate the mechanical deterioration of leather cup, and the working surface that expands leather cup is to improve its working efficiency.
Leather cup of the present utility model is realized by following scheme:
A kind of leather cup, its periphery is ring and end face is circle configurations, and wherein, end face has center hole, is characterized in, and end face is also rendered as upwards and arches upward, and leather cup thickness presents the variation reducing gradually to edge from center hole.
Like this, arch upward because leather cup end face is rendered as, and leather cup center thickness is compared with thick and edge thickness is thinner, thereby can makes it produce in the course of the work following variation: in the time that pull bar stretches to leather cup, its deformation of leather cup end face Tensile will be rendered as straight, and no longer occur the deformation of arc-shaped curved surface; In the time that pull bar compresses leather cup, leather cup end face will produce upset, and its end face deformation is subsequently also straight.
Thus obtained leather cup, its end face entirety participation role, be no longer confined to the part that contacts with pressing plate, thereby it is applied in the working efficiency that can improve air pump in air pump.
The leather cup of the invention, no matter stretch or the process of compression in, the deformation of leather cup end face will show to such an extent that be straight, avoid occurring arc deformation, thereby can alleviate leather cup in the course of the work because bending produces mechanical damage, and be conducive to improve the working life of leather cup.
Leather cup of the present utility model, in the process stretching or compress, is also accompanied by the upset of leather cup end face, can strengthen largely by upset the variable quantity of deformable cavity volume, is applied in the working efficiency that can improve to a greater degree air pump in air pump.
Air pump of the present utility model is realized by following scheme:
A kind of air pump, drives above-mentioned leather cup to swing in chamber by motor by pull bar, makes suction valve on chamber and gas outlet valve respectively in turn to opening and closing into and out of pore.
The air pump obtaining therefrom, have advantages of that usability is good, long service life and working efficiency high.
drawing explanation
Fig. 1 is the structural representation of air pump in prior art;
Fig. 2 is the structural representation of the utility model leather cup;
Fig. 3 be Fig. 2 leather cup along A-A to sectional view;
Fig. 4 is the structural representation of the utility model air pump.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete detailed description:
Referring to Fig. 2 and Fig. 3, leather cup 1 shown in figure is made up of rubber material, its side perimeters 11 peripheries are ring, its end face 12 is circle configurations, end face 12 has center hole 12a, end face 12 is also rendered as upwards and arches upward, and leather cup 1 thickness presents the variation tendency reducing gradually to periphery 11 from center hole 12a.
Referring to Fig. 4, air pump comprises leather cup 1, pressing plate 2, pull bar 3, motor 4, chamber 5, suction valve 6 and gas outlet valve 7, drive leather cup 1 to swing in chamber 5 by motor 4 by pull bar 3 and pressing plate 2, suction valve 6 and gas outlet valve 7 on chamber 5 are opened and closed inlet hole 8, air outlet hole 9 respectively in turn, make gas constantly enter chamber 5 from suction port via inlet hole 8, then flow out air outlet by chamber 5 through air outlet hole 9.
Claims (2)
1. a leather cup, its periphery is ring and end face is circle configurations, and wherein, end face has center hole, it is characterized in that, and end face is also rendered as upwards and arches upward, and leather cup thickness presents the variation reducing gradually to edge from center hole.
