Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple and reasonable, harmless, environment protection effect better, join strength is higher, working life is long, manufacture cost is lower mini pump.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mini pump described in the utility model, comprise cylindrical shell, the end cap and the valve that are connected with cylindrical shell two ends respectively, be located at the piston in cylindrical shell, and the pull bar being fixedly connected with piston, the end of described pull bar stretches out in the outside of end cap, described cylindrical shell is connected with valve, on described end cap, moulding is provided with the first sleeve with cylindrical shell interference fit, described first set jacket casing is located in cylindrical shell and is coordinated with described cylinder inboard wall clamping, the open-ended place of described cylindrical shell is provided with the second sleeve with valve interference fit, described the second jacket casing is located in valve and is coordinated with the clamping of valve inwall.
Further, on described first set drum outer wall, along being circumferentially provided with the first projection, described cylinder inboard wall is provided with first annular groove suitable with the first projection, and described the first sleeve coordinates with the first annular groove clamping by the first projection; On the outer wall of described the second sleeve, along being circumferentially with the second projection, described valve inwall is provided with second annular groove suitable with the second projection, and described the second sleeve coordinates with the second annular groove clamping by the second projection.
Further, described the second projection consists of two arcuation fins cooperations that are symmetrically set on the second sleeve outer wall.
Further, the front end of described valve is microcephaly and holds setting.
The beneficial effects of the utility model are: compared with prior art, the utility model is by the first sleeve of moulding setting on end cap and cylindrical shell interference fit, described first set jacket casing is located in cylindrical shell and is coordinated with described cylinder inboard wall clamping, the open-ended place of described cylindrical shell arranges the second sleeve with valve interference fit, described the second jacket casing is located in valve and is coordinated with the clamping of valve inwall, easy to assembly, during use, can not produce escaping gas, free from extraneous odour produces, environment protection effect is better, to health, can not impact; Join strength is higher, and end cap is difficult for coming off, and when coming off, still can guarantee that the bubble-tight while install again, use for convenience and the life-span longer; The Placement that adopts clamping to coordinate, die sinking cost is lower, easily manufactured, effectively reduces cost of production.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of mini pump as shown in Figure 1 to Figure 3, comprise cylindrical shell 1, the end cap 2 and the valve 3 that are connected with cylindrical shell 1 two ends respectively, be located at the piston 4 in cylindrical shell 1, and the pull bar 5 being fixedly connected with piston 4, the end of described pull bar 5 stretches out in the outside of end cap 2, described cylindrical shell 1 is connected with valve 3, on described end cap 2, moulding is provided with the first sleeve 21 with cylindrical shell 1 interference fit, described the first sleeve 21 is sheathed in cylindrical shell 1 and coordinates with described cylindrical shell 1 inwall clamping, the open-ended place of described cylindrical shell 1 is provided with the second sleeve 11 with valve 3 interference fit, described the second sleeve 11 is sheathed in valve 3 and coordinates with valve 3 inwall clampings.
Particularly, on described the first sleeve 21 outer walls, along being circumferentially provided with the first projection 22, described cylindrical shell 1 inwall is provided with first annular groove suitable with the first projection 22, and described the first sleeve 21 coordinates with the first annular groove clamping by the first projection 22; On the outer wall of described the second sleeve 11, along being circumferentially with the second projection 12, described valve 3 inwalls are provided with second annular groove suitable with the second projection 12, and described the second sleeve 11 coordinates with the second annular groove clamping by the second projection 12.
Working principle of the present utility model is identical with the working principle of existing pump, and therefore not to repeat here.
