Since the cleaning equipment and its inner box often need to be tilted and swung to adjust the angle during use, the fluid in the box will slosh and splash in the box, which makes it easy for the fluid to flow from the box to the load. The main suction port connected to the negative pressure generating device sucks the negative pressure generating device, thus damaging the motor.

At present, in order to solve the above problems, the method of actively reducing the effective volume of the tank is usually adopted, that is, a liquid level sensor, such as an electrode sheet, is installed on the tank body. When the liquid level exceeds the two electrode sheets, the two electrode sheets lead In this way, the liquid level can be detected by whether the electrode sheet is conductive, and the liquid full alarm can be realized, which can reduce the liquid level height when the liquid is full, and reduce the phenomenon that the liquid is sucked by the motor caused by the machine tilt and shaking. The disadvantage of the above solution is that it makes insufficient utilization of the tank, resulting in more frequent cleaning of the tank, which is inconvenient to use, and there is still a risk of fluid being sucked into the main suction port when the shaking is severe.

In this application, the advantages of the upper and lower distribution of the first chamber 210B and the second chamber 110B are: on the one hand, the separation of the solid medium and the liquid medium is realized, avoiding manual separation by the user; on the other hand, the second chamber 110B is a separate cavity and has no direct communication with the suction port 320B. When the box shakes under the influence of the external environment, the liquid medium in the box is not easy to enter the negative pressure generating device through the suction port 320B, which greatly reduces the pressure of the liquid medium. Due to the risk of splash being accidentally sucked by the suction port 320B, and the second chamber 110B does not need to be equipped with a liquid level detection unit, the storage capacity of the liquid medium in the second chamber 110B is effectively increased.

Wherein, the cross section of the suction pipe 120B is smaller than the cross section of the fluid pipe M, and the above cross section is a plane perpendicular to the axial direction of the pipe. Thus, a Venturi effect can be formed between the suction pipe 120B and the fluid pipe M, and the high-speed fluid in the fluid pipe M will promote the formation of negative pressure in the suction pipe 120B during the flow process, thereby making the second chamber 110B Create negative pressure.

Further, please continue to refer to Fig. 29, the fluid pipeline M has a large section at both ends and a small middle section, and the air extraction pipeline 120B is connected to the area with a small middle section of the fluid pipeline M, thus, the air extraction pipeline can be strengthened.

The first spring 272B abuts between the pressing portion 2712B and the second box body 200B in a compressed state, and the lock tongue 2713B is kept engaged with the buckle 340B under the action of the first spring 272B. When it is necessary to remove the cover assembly 300B from the second box body 200B, the user presses the pressing part 2712B to make the locking plate 271B rotate around the hinge shaft part 2711B. During the rotation of the locking plate 271B, the pressing part 2712B faces the second box body 200B is rotated, the lock tongue 2713B is rotated away from the buckle 340B, and the lock tongue 2713B is disengaged from the buckle 340B, so that the detachable connection between the second box body 200B and the box cover assembly 300B is realized.

In addition, it should be noted that the technical details mentioned in one of the above embodiments are still valid in other embodiments, and will not be repeated here to reduce repetition.
