SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model lies in, to prior art not enough, provide a life longer, help saving resource, the better micropump transmission of flexibility.

In order to solve the technical problem, the utility model adopts the following technical scheme.

The utility model provides a micropump transmission device, its includes the pump body, seted up the cavity in the pump body, set up on the pump body with the drain mouth that the cavity is linked together, be equipped with piston and two sliding connection in the cavity, the front end orientation of piston drain mouth, the rear end of piston is equipped with the actuating lever, the actuating lever extends to the outside of cavity, through ordering about the actuating lever back-and-forth movement and drive piston reciprocating motion.

Preferably, an annular sealing ring is embedded in the inner wall of the chamber, and the sealing ring surrounds the piston.

Preferably, the front end of the piston is provided with a notch.

Preferably, the rear end of the pump body is provided with an annular stepped port, the stepped port extends along the opening edge of the cavity, the sealing ring is accommodated in the stepped port, the rear end of the pump body is fixed with an annular cover plate, and the cover plate covers the stepped port, so that the sealing ring is limited between the cover plate and the stepped port.

Preferably, the seal ring is a grange seal ring.

The utility model discloses an among the micropump transmission, utilize the actuating lever orders about the piston and slides around, borrows by the piston and has realized the pump function with the cooperation of cavity, compares prior art, the utility model discloses can avoid influencing micropump normal use because of the sheet rubber drops, not only improve the life of micropump, alleviate the maintenance and the change work to the micropump moreover greatly, help saving resources, avoid extravagant, in addition, the utility model discloses only need control the relative cavity of piston and slide and can realize the pump function, its in-process need not to overcome the elasticity of sheet rubber, consequently the utility model discloses drive more easily, the flexibility is better, has satisfied the application demand betterly.

Drawings

FIG. 1 is a cross-sectional view of a prior art micro-pump;

fig. 2 is a sectional view of the micro-pump of the present invention.

Detailed Description

The present invention will be described in more detail with reference to the accompanying drawings and examples.

The utility model discloses a micropump transmission device, please see fig. 2, it is including the pump body 1, cavity 2 has been seted up in the pump body 1, set up on the pump body 1 with the drain mouth 3 that cavity 2 is linked together, be equipped with piston 4 and the two sliding connection in the cavity 2, the front end orientation of piston 4 drain mouth 3, the rear end of piston 4 is equipped with actuating lever 5, actuating lever 5 extends to the outside of cavity 2 is through ordering about 5 back-and-forth movement of actuating lever and drive piston 4 reciprocating motion.

In the structure, utilize actuating lever 5 orders about piston 4 and slides around, borrows by piston 4 and cavity 2's mating reaction and has realized the pump function, compares prior art, the utility model discloses can avoid influencing micropump normal use because of the sheet rubber drops, not only improve the life of micropump, alleviate the maintenance and the change work to the micropump moreover greatly, help saving resources, avoid extravagant, in addition, the utility model discloses only need control piston 4 relative cavity 2 to slide can realize the pump function, its in-process need not to overcome the elasticity of sheet rubber, consequently the utility model discloses drive more easily, the flexibility is better, has satisfied the application demand betterly.

In order to achieve the sealing function, in this embodiment, an annular sealing ring 6 is embedded in the inner wall of the chamber 2, and the sealing ring 6 surrounds the piston 4.

In order to further expand the compression space in the chamber 2, the front end of the piston 4 is provided with a notch 7 in the embodiment.

For edge mounting and fixed seal ring, in this embodiment, annular ladder mouth 8 has been seted up to the rear end of pump body 1, ladder mouth 8 is followed the opening edge of cavity 2 extends, sealing washer 6 holding in ladder mouth 8, the rear end of pump body 1 is fixed with annular apron 9, apron 9 cover in ladder mouth 8, and then will sealing washer 6 restriction is in apron 9 with between the ladder mouth 8.

In order to improve the sealing performance, the seal ring 6 is preferably a glan seal ring in the present embodiment.

The utility model discloses a micropump transmission, it removes the sheet rubber and directly adopts the mode of piston on traditional transmission's basis, seals with the glan sealing washer simultaneously, makes the transmission life-span of pump longer, still avoids the chemical reaction between rubber and different liquid simultaneously. To sum up, the utility model has the characteristics of simple structure, easily processing, with low costs, practicality are strong etc, be fit for popularizing and applying in the micropump product to better application prospect has.
