The other part is communicated with the sewage chamber 11, so that part of the dirt in the solid-liquid separation cavity 21 is stored in the sewage chamber 11.

It can be understood that, because the solid-liquid separation cavity 21 is located on the handle 20 and is higher than the sewage chamber 10, under the action of gravity, liquid and part of small particle solid in the sewage can enter the sewage chamber 10 through the flow pipeline to be stored, and the remaining larger solid garbage can not pass through the flow pipeline and is retained in the solid-liquid separation cavity 21, so that solid-liquid separation is realized.

In this embodiment, the cleaning device has a sewage chamber 11 for storing sewage formed in the body 10, and a solid-liquid separation chamber 21 formed in a handle 20 rotatably connected to the body 10 and communicating with the same, so that liquid in a solid-liquid mixture of solid-liquid waste is separated in the solid-liquid separation chamber 21 and then guided out to the sewage chamber 10 of the lower body by gravity. From this, in cleaning device use, can be with the effective separation of solid-liquid rubbish in the storage of different regions, conveniently take out and discharge the clearance, promoted user experience.

In the present embodiment, after the dirty solid-liquid mixture is separated on the handle 20, the solid waste is stored in the solid-liquid separation cavity 21, and the dirty liquid is guided to the sewage chamber 11 for storage. Therefore, after solid-liquid garbage is separated, a user can directly and separately process the dirty liquid in the sewage chamber 11 and the solid garbage in the solid-liquid separation cavity 21, the equipment cleaning steps of the user are saved, the labor intensity of the user is reduced, and the user can conveniently and quickly clean the machine equipment after sweeping the floor by using the cleaning device.

In this embodiment, since the first bent portion and the second bent portion are both hard pipes and the inner surfaces thereof are both formed as smooth surfaces, the inner surfaces of the first bent portion and the second bent portion can be polished, so that the solid-liquid contamination can be prevented from accumulating or adhering in the first bent portion and the second bent portion.

In one embodiment, the sewage treatment device further comprises a power member for pumping the liquid in the solid-liquid separation cavity 21 into the sewage chamber 11.

Specifically, the power members are divided into a pneumatic power member 60a and a hydraulic power member 60 b;

the principle of the aerodynamic member 60a is described in detail below:

the gas power part 60a is communicated with the sewage chamber 11 and is used for pumping gas in the sewage chamber 11 to the outside, so that solid-liquid separation of the solid-liquid separation cavity 21 can be more thorough under the action of the gas power part 60a, and liquid in the solid-liquid separation cavity 21 can be helped to well enter the sewage chamber 11.

As an alternative to this embodiment, with reference to fig. 4, the cleaning device is provided with both a pneumatic element 60a and a suction assembly 50. At this time, the aerodynamic member 60a and the suction unit 50 together generate a negative pressure in the solid-liquid separation chamber 21 to form a negative pressure environment, and the liquid is driven from the soil suction port 13 to the solid-liquid separation chamber 21 and then from the solid-liquid separation chamber 21 to the sewage chamber 12.

As an alternative to this embodiment, the cleaning device is provided with only the aerodynamic member 60a and no suction assembly 50. At this time, the gas dynamic element 60a generates a negative pressure in the solid-liquid separation chamber 21 through the sewage chamber 11 to form a negative pressure environment, and drives the liquid from the sewage suction port 13 to the solid-liquid separation chamber 21 and then from the solid-liquid separation chamber 21 to the sewage chamber 12.

The principle of the hydrodynamic element 60b is explained in detail below:

referring to fig. 5, the liquid power member 60b is disposed on the second pipeline 40, the liquid pumping end is connected to the pipeline on the side of the solid-liquid separation cavity 21, the liquid outlet end is connected to the sewage chamber 11, the solid-liquid separation of the solid-liquid separation cavity 21 can be performed more thoroughly under the action of the liquid power member 60b, and the liquid in the solid-liquid separation cavity 21 can be better introduced into the sewage chamber 11.

The liquid power part 60b can also be arranged in the solid-liquid separation cavity 21, the liquid drawing end is connected with the liquid in the solid-liquid separation cavity 21, and the liquid port is communicated with the second pipeline 40.

Preferably, the pipes connected to the soil chamber 11 are all provided at the upper portion of the soil chamber 11 to prevent the reduction of the effective utilization rate of the soil chamber volume.

The pneumatic member 60a may be a blower or an air pump such as a vacuum pump, a diaphragm pump, or the like.

The hydrodynamic element 60b may be a liquid pump or the like.

In one embodiment, the second inlet is disposed at the upper part of the solid waste chamber 211; the second dirty outlet is provided at the lower part of the liquid chamber 212; the first soil inlet 111 is provided at an upper portion of the soil chamber 11.

In one embodiment, the first soil inlet 111 is disposed at a lower portion of the soil chamber 11, and a valve is disposed to control opening and closing of the first soil inlet, and when a user takes off the soil chamber 11, the valve controls the first soil inlet 11 to be closed, thereby preventing the soil in the soil chamber 11 from flowing out.

Specifically, the second dirty inlet is arranged on the upper portion of the side wall of the solid waste chamber 211 or the top wall of the side wall, so that the dirty mixture can fall down under the action of gravity after entering the solid waste chamber 211 from the second dirty inlet, and the effective utilization rate of the volume of the solid waste chamber 211 is improved.

The second dirty outlet can be opened in the lower part of the lateral wall of the liquid chamber 212 or the bottom of the liquid chamber 212, so that the liquid in the liquid chamber 212 can be guided out under the action of gravity, and the phenomenon of liquid accumulation is prevented. Secondly, the second sewage outlet is arranged at the lowest position of the bottom of the solid-liquid separation cavity 21, and if the second sewage outlet is arranged at the bottom of the solid-liquid separation cavity 21, the sewage liquid after solid-liquid separation can flow back to the sewage chamber 11 at the bottom by gravity, so that liquid accumulation in the solid-liquid separation cavity 21 is avoided.

First dirty mouthful 111 sets up at the very top of sewage room 11, if set up on the roof of sewage room 11 to improve the volume utilization ratio in the sewage room 11, save more sewage, thereby reduce the frequency that sewage was emptyd in the cleaning process.

In one embodiment, the solid-liquid separation chamber 21 can be detachably connected with the handle 20, so that the solid-liquid separation chamber 21 can be removed and cleaned when solid garbage is accumulated in the solid-liquid separation chamber 21. For example, the solid-liquid separation chamber 21 can be detachably connected to the handle 20 by means of a snap, a protrusion, a screw thread, or other equivalent quick-release structure.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
