Detailed description of the invention

For the ease of understanding this utility model, below in conjunction with the accompanying drawings this utility model is further detailed.

As it is shown in figure 1, this utility model is for the Self-priming pump device of liquid vending machine, motor 2 front end is inserted in the pump housing 1, electricity The head of machine 2 is connected with impeller；Conveying pipe 11 connects with the pump housing 1；Circular retaining wall 12, ring vertically it is provided with on the pump housing 1 Shape barricade 12 connects with the pump housing 1；Being provided with filter element 3 in circular retaining wall 12, filter element 3 overcoat has the mistake for fixing filter element 3 Filter ruffle cylinder 4, whole filter element 3 is covered and fixes with the pump housing 1 and is connected by filter sleeve 4, and filter sleeve 4 one aspect makes filter element 3 It is positioned in sealed environment, on the one hand there is the fixation to filter element 3.

Concrete, as it is shown in figure 1, for the sealing ensureing filter element 3 junction, be provided with the first sealing in the upper end of filter element 3 Silica gel 31, first to seal silica gel 31 be the circular silica gel piece that the opening with filter element 3 upper end matches, first seal silica gel 31 and The top laminating of filter element 3 is stretched in filter sleeve 4 the most together, withstands on the inside top surface of filter sleeve 4；Lower end is provided with second Sealing silica gel 32, the second shape sealing silica gel 32 matches with circular retaining wall 12, and whole second seals silica gel 32 is stuck in ring In shape barricade 12, centre is provided with the circular hole identical with filter element 3 external diameter and inserts for filter element 3；In order to improve further filter element 3 with The sealing of circular retaining wall 12 junction, second seal silica gel 32 chimb is arranged below, chimb is interior with circular retaining wall 12 Surface interference fit, it is possible to snap in circular retaining wall 12, improves the second sealing silica gel 32 to sealing herein.

It is preferred that, filter sleeve 4 is connected by screw is fixing with the pump housing 1, it is ensured that the steadiness that both connect, simultaneously Screw is easy to connect to be dismantled filter sleeve 4 when changing filter element 3.

In order to ensure that conveying pipe 11 and the pump housing 1 junction will not produce the leakage of liquid, conveying pipe 11 is molded into the pump housing 1 Integrative-structure.

As Figure 1 and Figure 4, other position of the pump housing 1 is all overall sealing surface, is installing the part such as impeller of the pump housing 1 Time, need the lateral opening at the pump housing 1, in order to install the part in the pump housing 1 cavity, the sealing of this opening part is the heaviest Want；In the present embodiment, opening shape is four circles being connected, and is provided with the 3rd sealing silica gel 5 in opening, and the 3rd seals The shape of silica gel 5 matches with opening, and with opening interference fit, the 3rd sealing silica gel 5 is snapped in opening, then outside Gland 6 is set closure of openings, gland 6 are fixed by screws in opening part.

Owing to motor 2 produces vibrations in the running, the vibrations of other parts can be caused simultaneously, be likely to result in junction because of long-time Shake and make sealing reduce, also can produce noise, motor 2 is cased with at least one shockproof silica gel 7, damping can be played and make With, also can reduce noise simultaneously.

Self-priming pump device also needs to be connected with other parts of liquid vending machine, and the side at shockproof silica gel 7 is provided with the fixing of base-like Block, each face of fixed block is designed with connecting hole 71, is used for connecting miscellaneous part.
