Background

Cleaning devices, such as vacuum cleaners, floor washers, etc., generally have a cleaning head for moving over a surface to be cleaned and an upright body connected to the cleaning head, and the body is provided with a handle for being held by a human hand to push the cleaning head to move over the surface to be cleaned.

The body is usually provided with a negative pressure generating device for generating negative pressure, and the negative pressure generating device may include, for example, a motor and a fan driven by the motor, and the motor drives the fan to rotate to generate negative pressure. The cleaning head is provided with an air suction opening facing the surface to be cleaned, the air suction opening is communicated with the negative pressure generating device, and the sewage, scraps, hair and other dirt on the surface to be cleaned are sucked into a box body in the machine body through the suction force generated by the negative pressure generating device.

Because the cleaning equipment body and the box body in the cleaning equipment body often need to incline and swing to adjust the angle in the using process, fluid in the box body can shake and splash in the box body, and the fluid is easy to suck into the negative pressure generating device from the main suction inlet communicated with the negative pressure generating device on the box body, so that a motor is damaged.

At present, in order to solve the above problems, a mode of actively reducing the effective volume of the tank body is generally adopted, that is, a liquid level sensor, such as an electrode plate, is arranged on the tank body, when the liquid level exceeds two electrode plates, the two electrode plates are conducted, so that whether the liquid level is detected through conducting the electrode plates or not is the liquid level, the liquid level full alarm is realized, the liquid level height when the liquid level is full can be reduced, and the phenomenon that the liquid caused by machine inclination and shaking is sucked by a motor is reduced. The defect of the scheme is that the utilization degree of the box body is not sufficient, the frequency of cleaning the box body is more frequent, the use is inconvenient, and the risk that fluid is sucked into the main suction inlet still exists when the box body shakes violently.

Accordingly, there is a need for improvements in the art that overcome the deficiencies in the prior art.

Example one

Referring to fig. 1 to 14, the present invention provides a case, including: a first case 100, a second case 200, and a cover assembly 300. The first box 100 and the second box 200 are both hollow, and the second box 200 is accommodated in the hollow cavity of the first box 100. The top of the first and

second cases

100 and 200 is open, and the cover assembly 300 is detachably provided to the top open ends of the first and

second cases

100 and 200.

In the present invention, referring to fig. 2 to 4 and 12, the second casing 200 is located at the upper portion of the hollow cavity of the first casing 100, a first chamber 210 is formed inside the second casing 200, and a second chamber 110 located below the first chamber 210 is formed inside the first casing 100. The second tank 200 is provided with at least one filter hole 220, and the filter hole 220 communicates the first chamber 210 and the second chamber 110.

A fluid pipe M having a fluid outlet end is disposed in the first casing 100, and a fluid outlet M is disposed on the fluid outlet end_{Mouth piece}. Fluid discharge port M_{Mouth piece}Is disposed within the first chamber 210 for delivering fluid to the first chamber 210.

The fluid in the present invention refers to a solid-liquid mixture, and in an exemplary scenario, the fluid is a mixture of dirt and sewage collected by the cleaning device during the cleaning task. It is understood that the fluid includes, but is not limited to, a mixture of dirt and sewage collected by the cleaning apparatus, and may also be a mixture of solid and liquid produced or collected by other apparatus.

Referring to fig. 14, the cover assembly 300 is provided with a suction port 320 communicating with a negative pressure generating device (not shown), and the suction port 320 is located at the top of the second casing 200. The negative pressure generating means communicates with the first chamber 210 of the second casing 200 through the suction port 320 to allow external fluid to enter the first chamber 210 through the fluid pipe M.

After the fluid enters the first chamber 210, the liquid medium in the fluid flows into the second chamber 110 through the filtering holes 220 under the action of self gravity, and the solid medium in the fluid is retained in the first chamber 210, so that the liquid medium and the solid medium are separated.

In the present invention, the advantage of the up-and-down distribution of the first chamber 210 and the second chamber 110 is that: on one hand, the separation of the solid medium and the liquid medium is realized, and the manual separation of a user is avoided; on the other hand, the second chamber 110 is a separate cavity and is not directly communicated with the suction port 320, when the box body shakes under the influence of the external environment, the liquid medium in the box body is not easy to enter the negative pressure generating device through the suction port 320, the risk that the liquid medium is mistakenly sucked by the suction port 320 due to splashing is greatly reduced, and the liquid level detection unit is not required to be arranged on the second chamber 110, so that the liquid medium storage capacity of the second chamber 110 is effectively increased.

In order to make the liquid medium in the fluid entering the first chamber 210 flow into the lower second chamber 110 better, a more desirable solid-liquid separation effect is achieved. An exhaust duct 120 is disposed in the first box 100, and the exhaust duct 120 is used for driving the second chamber 110 to generate a negative pressure. The negative pressure has a suction effect on the fluid in the first chamber 210, so that the liquid medium in the fluid in the first chamber 210 flows into the second chamber 110 under the dual effects of the self gravity and the suction, and the effect of solid-liquid separation is effectively improved.

In the present invention, the second casing 200 is provided with a connection port 260 for communicating the first chamber 210 with the second chamber 110, and the suction duct 120 is connected to the connection port 260.

Specifically, the pumping duct 120 is located in the first chamber 210, and one end of the pumping duct 120 is communicated with the side wall of the fluid duct M, and the other end is communicated with the connection port 260.

Wherein the cross-section of the pumping duct 120 is smaller than the cross-section of the flow duct M, which is a plane perpendicular to the axial direction of the duct. Therefore, a venturi effect can be formed between the pumping duct 120 and the fluid duct M, and the high-speed fluid in the fluid duct M can cause a negative pressure to be formed in the pumping duct 120 in the flowing process, so that a negative pressure is formed in the second chamber 110.

Further, as shown in fig. 2, the fluid pipeline M has a large cross section at both ends and a small cross section at the middle, and the pumping pipeline 120 is connected to the area with the small cross section at the middle of the fluid pipeline M, so that the venturi effect between the pumping pipeline 120 and the fluid pipeline M can be enhanced, and the negative pressure in the second chamber 110 can be increased to facilitate the solid-liquid separation. It is understood that the fluid conduit M and the air exhaust conduit 120 may be integrally disposed or separately disposed.

In another possible implementation, referring to FIG. 8, the second chamber 110 is connected to the first chamber 210 through the pumping duct 120. The bottom end of the pumping duct 120 is disposed at the connection port 260, and the top end of the pumping duct 120 is disposed in the first chamber 210. The pumping duct 120 extends generally in the direction from the second chamber 110 to the first chamber 210.
