In the sealing structure of the electrode and the end cover in the washing pump, the peripheral side walls of one end of the strip-shaped hole, which is positioned in the end cover, are all inclined guide surfaces. Under the action of the guide surface, the insertion piece can be conveniently arranged in the rubber part.

In the sealing structure of the electrode and the end cover in the washing pump, the rubber piece is tightly matched and fixedly connected with the end cover through the sealing part. By adopting the design, the device has the advantages of simple structure and convenience in installation.

Compared with the prior art, the sealing structure of the electrode and the end cover in the washing pump has the following advantages:

1. the sealing part on the rubber pad forms sealedly with inserted sheet and end cover respectively, makes to form reliably sealed between inserted sheet and the end cover, can prevent effectively then that impurity such as dust, water from entering into the washing pump inside, so not only can prolong the life-span of washing pump, can also make the washing pump can be applicable to more complicated operating mode, improves the practicality of washing pump.

2. The head that is T shape and is used for hiding the through-hole internal orifice is increased on the rubber spare, both can be used to the length that restriction sealing stretches into in the through-hole, makes the disposable installation of rubber spare target in place, can make again and form secondary seal between rubber spare and the end cover, effectively strengthens the sealed effect of rubber spare and end cover, further strengthens the life-span and the practicality of washing pump.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and fig. 3, in the sealing structure of the electrode and the end cap in the washing pump, the electrode comprises a positive electrode and a negative electrode, strip-shaped insertion pieces 1 are arranged on the positive electrode and the negative electrode, a through hole 2a is arranged on the end cap 2, and the two insertion pieces 1 extend out of the through hole 2 a. Two inserted sheet 1 vertical settings, through-hole 2a are the T shape, and through-hole 2a comprises hole one 2a1 and hole two 2a2 that are linked together, and hole one 2a1 and hole two 2a2 are all the strip and both are mutually perpendicular, and two inserted sheet 1 pass through hole one 2a1 and hole two 2a2 respectively.

As shown in fig. 2, fig. 3, fig. 4 and fig. 5, the sealing structure includes a rubber member 3 fixedly disposed in the end cap 2, the rubber member 3 has a T-shaped sealing portion 3a matching with the through hole 2a, the sealing portion 3a is disposed in the through hole 2a, and a side wall of the sealing portion 3a is in close contact with a hole wall of the through hole 2a to form a seal. In this embodiment, the rubber member 3 is fixedly connected with the end cap 2 by the tight fit of the sealing portion 3 a. Run through on the rubber spare 3 and be equipped with two bar holes 3b that supply two inserted sheets 1 to pass respectively, the one end in bar hole 3b extends to sealing portion 3a, and the lateral wall of inserted sheet 1 and the pore wall in bar hole 3b in close contact with form sealedly. Sealing 3a on the rubber pad forms sealedly with inserted sheet 1 and end cover 2 respectively, makes to form reliably sealed between inserted sheet 1 and the end cover 2, can prevent effectively then that impurity such as dust, water from entering into the washing pump inside, so not only can prolong the life-span of washing pump, can also make the washing pump can be applicable to more complicated operating mode, improves the practicality of washing pump.
