In order to solve the exhaust problem, the prior art installs the exhaust valve at the outlet, and outside drain pipe is connected with the exhaust valve again. Therefore, the air in the pump body and the pipe can be quickly discharged, and the water is discharged in 3-5 seconds.

SUMMERY OF THE UTILITY MODEL

The technical problems solved by the utility model are as follows: on the premise of exhausting, the external drain pipe can be directly connected with the water outlet of the pump body.

In order to solve the technical problems, the utility model provides the following technical scheme: a cleaning machine comprises a shell, a water pump arranged in the shell, a water inlet pipe connected with the water pump, and a water outlet pipe connected with the water pump, wherein an exhaust valve is arranged on the water outlet pipe, the exhaust valve is positioned in the shell, and the water outlet end of the water outlet pipe is positioned outside the shell.

The water outlet end of the water outlet pipe is equivalent to a water outlet in the prior art. The external drain pipe can be directly arranged at the water outlet end without transition through an exhaust valve. Therefore, compared with the prior art, the exhaust valve is arranged in the shell of the cleaning machine, the external drain pipe can be directly connected with the water outlet end on the premise of ensuring exhaust, the installation is convenient, and the external structure of the cleaning machine is simplified.

Detailed Description

Referring to fig. 1 and 2, the cleaning machine includes a housing 10, a water pump 20 disposed in the housing, a water inlet pipe 21 connected to the water pump, and a water outlet pipe 22 connected to the water pump, wherein an exhaust valve 30 is disposed on the water outlet pipe, the exhaust valve is located in the housing, and a water outlet end 220 of the water outlet pipe is located outside the housing.

In practice, the external drain pipe is directly connected to the outlet end 220 of the outlet pipe, and the water pump 20 operates to absorb external water through the inlet pipe 21 and discharge the water through the outlet pipe 22 and the external drain pipe at high pressure. Due to the existence of the exhaust valve 30, air in the water pump and the water inlet pipe 21 and the water outlet pipe 22 can be rapidly exhausted when the water pump is operated, so that the air is prevented from becoming a retardation factor of water drainage, and therefore, water can be rapidly exhausted from an external drain pipe after the water pump 20 is operated.

Referring to fig. 3 to 5, the exhaust valve 30 includes a valve body 31 disposed on the water outlet pipe 22, a valve seat 32 fitted in the valve body, and a valve core 33 disposed in the valve body and elastically fitted with the valve seat, and the valve seat is provided with an exhaust passage 320. Wherein the valve body 31 is integrally formed with the outlet pipe 22. During exhaust, air is exhausted through the gap between the valve seat and the valve core and then through the exhaust passage 320. If water acts on the valve element 33, the valve element abuts against the valve seat 32 against the elastic force between the valve element and the valve seat, sealing the exhaust passage 320. Alternatively, the valve core 33 is a ball, the ball abuts against the inner side wall of the valve body 31, and a spring 34 is arranged between the ball and the valve seat to realize the elastic connection between the valve core and the valve seat. The top end of the valve seat 32 is provided with a seal ring 35 which seals a gap between the valve body 31 and the valve seat and which can seal the exhaust passage 320 by abutting against the valve element 33 when the spring 34 is compressed.

With reference to fig. 4 and 5, the valve seat 32 is provided with a clamping portion 321 with a rectangular outer contour, a positioning portion 322 is provided below the clamping portion, the valve body 31 and the connection port 310 of the valve seat are rectangular, a clamping groove 311 is provided on the inner side wall of the valve body, and a positioning groove 312 is provided below the clamping groove. During actual assembly, the rectangular clamping portion 321 is aligned with the rectangular connecting port 310, when the clamping portion is inserted into the connecting port 310 from bottom to top and is as high as the clamping slot 311, the clamping portion 321 is rotated, a pair of short edges of the clamping portion are clamped into the corresponding clamping slots 311, and the positioning portions 322 are synchronously clamped into the corresponding positioning slots 312, so that the valve body is connected with the valve seat. As a modification, the two end portions of the card slot 311 are provided with escape holes 313. When the clamping portion 321 rotates, the rectangular clamping portion can abut against the inner wall of the valve body 31 and cannot rotate, and the avoiding hole provides a condition for 90-degree rotation of the clamping portion, so that the clamping portion can rotate smoothly, and the rectangular short edge of the clamping portion can be clamped into the corresponding clamping groove 311. As an improvement, in the connection port 310 of the valve body and the valve seat, a pair of rectangular short sides are arc-shaped sides, and correspondingly, a pair of rectangular short sides of the clamping portion 321 are arc-shaped sides, so that the clamping portion can rotate smoothly in the valve body 31.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
