Detailed Description

As shown in fig. 1, 2 and 3, the hand-held washing machine is provided with a delivery part 1 and a booster pump which are of an integrated structure, and the main parts of the delivery part 1 and the booster pump are arranged in the hand-held washing machine.

The conveying part 1 is internally provided with a pipeline for water delivery, which comprises a low-pressure water inlet pipeline 2, a high-pressure water outlet pipeline 4 and a pressure relief pipeline 6. The extension direction of the low-pressure water inlet pipeline 2 in the conveying component 1 is perpendicular to the extension direction of the high-pressure water outlet pipeline 4 in the conveying component 1, and the extension direction of the pressure relief pipeline 6 in the conveying component 1 is parallel to the extension direction of the low-pressure water inlet pipeline 2 in the conveying component 1. One end of the low-pressure water inlet pipeline 2 forms a low-pressure water inlet on the conveying component 1, and the other end of the low-pressure water inlet pipeline 2 forms a low-pressure water outlet 3 on the conveying component 1. The low-pressure water outlet 3 corresponds to a water inlet of the booster pump, and the low-pressure water inlet pipeline 2 is communicated with the water inlet of the booster pump. One end of the high-pressure water outlet pipeline 4 forms a high-pressure water inlet 5 on the conveying component 1, and the other end of the high-pressure water inlet pipeline forms a high-pressure water outlet on the conveying component 1. The high-pressure water outlet corresponds to the water outlet of the booster pump, and the high-pressure water outlet pipeline 4 is communicated with the water outlet of the booster pump. One end of the pressure relief pipeline 6 is communicated with the high-pressure water outlet pipeline 4, and the other end of the pressure relief pipeline 6 is communicated with the low-pressure water inlet pipeline 2. A pressure relief assembly is distributed in the pressure relief pipeline 6 and comprises a spring 7, a steel ball 8 and a pressure plate 9. The pressure relief pipeline 6 is internally provided with a sealing bulge 10, the cross section of a conveying space between the pressure relief pipeline 6 and the high-pressure water outlet pipeline 4 is reduced by the sealing bulge 10, and the sealing bulge 10 is provided with a groove structure with a spherical surface, and the groove structure corresponds to the steel ball 8. The shape of the cross-sectional profile of the pressure plate 9 is the same as the shape of the cross-sectional profile of the pressure relief duct 6, but the size of the cross-sectional profile of the pressure plate 9 is smaller than the size of the cross-sectional profile of the pressure relief duct 6, the pressure plate 9 being slidable within the pressure relief duct 6. One end of the pressing plate 9 is provided with a mounting hole corresponding to the spring 7, and the other end of the pressing plate 9 is provided with a limiting groove corresponding to the steel ball 8. Spring 7 is in pressure release pipeline 6 inside with compression state, and spring 7's one end and pressure release pipeline 6 inner wall swing joint, spring 7's the other end embedding are in the mounting hole, and steel ball 8 embedding is in the spacing inslot. The inner diameter of the sealing bulge 10 is smaller than the outer diameter of the steel ball 8, and the steel ball 8 is movably connected with the sealing bulge 10 and embedded in the groove of the sealing bulge 10.

In the initial state, the spring 7 pushes the steel ball 8 to promote the tight connection between the steel ball 8 and the sealing protrusion 10. After the booster pump works, the externally sucked water flow enters the booster pump through the low-pressure water inlet pipeline 2, and the high-pressure water flow output by the booster pump is output outwards through the high-pressure water outlet pipeline 4. If the high-pressure water outlet pipeline 4 is closed, the high-pressure water flow pushes the steel ball 8 to overcome the elastic force of the spring 7 and drive the steel ball 8 to be separated from the sealing bulge 10, so that the water flow starts to flow into the pressure relief channel, the water flow in the pressure relief channel flows into the low-pressure water inlet pipeline 2, the water flow flows back into the booster pump, and the water flow output by the booster pump can be started to continuously flow.
