[0024] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] Reference Figure 1-4 A cleaning device is provided, comprising:

[0026] Water tank 1; the water tank 1 is provided with a solid material chamber 11 and a liquid material chamber 12 connected vertically. The solid material chamber 11 is provided with a first conveying channel that connects to a sewage source outside the water tank 1. The liquid material chamber 12 is provided with a second conveying channel that connects to a negative pressure source outside the water tank 1. The negative pressure airflow generated by the external negative pressure source flows from the first conveying channel through the solid material chamber 11 and the liquid material chamber 12 to the second conveying channel.

[0027] In this embodiment of the application, a cleaning device is proposed, which includes a water tank 1. The water tank 1 is provided with a solid material chamber 11 and a liquid material chamber 12 connected vertically. The solid material chamber 11 is provided with a first conveying channel communicating with a sewage source outside the water tank 1, and the liquid material chamber 12 is provided with a second conveying channel communicating with a negative pressure source outside the water tank 1. The negative pressure airflow generated by the external negative pressure source flows from the first conveying channel through the solid material chamber 11 and the liquid material chamber 12 to the second conveying channel. Through the negative pressure airflow direction formed by the sewage source flowing from the first conveying channel through the solid material chamber 11 and the liquid material chamber 12 to the second conveying channel, the sewage source sewage is drawn into the solid material chamber 11 under the action of negative pressure. The solid material in the sewage remains in the solid material chamber 11, and the liquid material flows into the liquid material chamber 12 under the action of gravity. At the same time, the airflow flows from the solid-liquid chamber to the liquid material chamber 12. Under the continuous action of negative pressure, the liquid material is driven to flow faster into the liquid material chamber 12, which achieves the effect of rapid solid-liquid separation.

[0028] The cleaning device described above will be further explained below through the following embodiments.

[0029] In one embodiment of this application, the cleaning device further includes: a solid-liquid separation element;

[0030] The solid-liquid separator is located inside the water tank 1 and divides the interior of the water tank 1 into the solid material chamber 11 and the liquid material chamber 12.

[0031] The solid-liquid separation component may include baffles with mesh, nets, or other objects that prevent solid waste from falling from the solid material chamber 11 into the liquid material chamber 12 and ensure that liquid waste can flow smoothly from the solid material chamber 11 into the liquid material chamber 12.

[0032] In one embodiment of this application, the solid-liquid separation component includes a separable filter screen 2. The filter screen 2 includes a filter surface 21 and a side wall 22 surrounding and connecting the filter surface 21. The filter surface 21 and the side wall 22 surround and form the solid material cavity 11. The top of the side wall 22 is provided with a hanging lug 23 that overlaps with the top edge of the water tank 1.

[0033] Understandably, in the aforementioned filter screen 2, a basin-shaped solid material chamber 11 is suspended inside the water tank 1 by means of a hanging ear 23 that overlaps the top of the water tank 1 and is connected to the filter surface 21 via a side panel 22. The space at the bottom of the solid material chamber 11 inside the water tank 1 is the liquid material chamber 12. When the air pressure inside the solid material chamber 11 and / or the water tank 1 is lower than the external air pressure, the resulting negative pressure will draw the dirt into the solid material chamber 11. The solid dirt in the dirt will accumulate above the filter surface 21, while the liquid dirt will flow into the liquid material chamber 12 through several filter holes of the filter surface 21 and be deposited.

[0034] In one embodiment of this application, the filter surface 21 has a first hole 24, and the bottom of the water tank 1 has a first conveying pipe 3 that passes through the liquid material chamber 12 and the first hole 24 in sequence to connect the outside of the water tank 1 and the solid material chamber 11. The first conveying pipe 3 constitutes the first conveying channel.

[0035] It should be noted that the water tank 1 provided in this application is mainly used as a base station for the sweeper to collect the dirt after the sweeper finishes cleaning. This embodiment provides a specific solution for airflow and dirt guidance. Through the first conveying pipe 3 that runs through the bottom of the tank and directly into the solid material chamber 11, it matches the action of the sweeper on the ground to transport the dirt from bottom to top.

[0036] It should also be noted that the first conveying pipe 3 and the water tank 1 can be integrally formed, which prevents water leakage if the connection is made by disassembly, thus ensuring the internal structure is stable.

[0037] In the above embodiment, the concentrated stress caused by the first hole 24 in the filter surface 21, coupled with the gravity of the solid contaminants around the first hole 24, may exceed the original tolerance of the local filter surface 21 around the first hole 24. This may cause the edge of the first hole 24 to sag, creating a gap between the first hole 24 and the first conveying pipe 3 where solid contaminants may leak out, thus affecting the solid-liquid separation effect. To address this, the edge of the first hole 24 is provided with a protrusion 25 extending into the solid material cavity 11, and the protrusion 25 has a second hole 26 adapted to the first conveying pipe 3.

[0038] It should be noted that the protrusion 25 can disperse stress and improve the load-bearing capacity of the filter surface 21. On the other hand, the first conveying pipe 3 is adapted to the second hole 26 of the protrusion 25, which further improves the structural strength of this part.

[0039] In one embodiment of this application, the horizontal height of the filter surface 21 is higher than the preset liquid level height of the liquid chamber 12, and the horizontal height of the second conveying channel is higher than the preset liquid level height of the liquid chamber 12.

[0040] Understandably, by ensuring that the horizontal height of the filter surface 21 is higher than the preset liquid level height of the liquid chamber 12, it is possible to prevent liquid contaminants from entering solid contaminants due to excessively high water levels in the liquid chamber 12, thus affecting the solid-liquid separation effect.

[0041] The second conveying channel is at a higher level than the preset liquid level of the liquid chamber 12, to prevent the negative pressure source from sucking out the liquid contaminant.

[0042] In one embodiment of this application, a HEPA filter 5 is provided at the opening of the second conveying channel.

[0043] It should be noted that during the solid-liquid separation process inside water tank 1, extremely small dust particles may pass through filter screen 2 and the space of liquid chamber 12, reaching the second conveying channel with the airflow direction. Therefore, a HEPA filter 5 is installed to prevent dust from entering the negative pressure source through the second conveying channel. HEPA filter 5 is a high-efficiency filter that can block extremely small dust particles.

[0044] In one embodiment of this application, an openable and closable lid 6 is also included. The lid 6 is connected to the top edge of the water tank 1 by a hinge, and a first sealing ring 61 is provided between the top of the side panel 22 and the lid 6.

[0045] The above embodiment provides a removable solid-liquid separator structure. When the solid waste inside the solid-liquid separator accumulates to a certain amount, it can be removed by opening the cover 6. The protrusions 25 on the filter surface 21 also facilitate lifting.

[0046] When the lid 6 is closed, the top space of the solid-liquid separation component is sealed by the first sealing ring 61 to prevent airflow from the top, thereby preventing solid waste from being carried out from the top.

[0047] In one embodiment of this application, a second sealing ring 62 is provided between the edge of the tank cover 6 and the water tank 1. An airflow cavity 13 is formed between the tank cover 6, the second sealing ring 62, the reserved area of ​​the hanging ear 23, and the first sealing ring 61. The reserved area of ​​the hanging ear 2 is provided with a HEPA groove that connects the airflow cavity 13 and the liquid chamber 12. The HEPA 5 is installed in the HEPA groove. The outer wall of the water tank 1 is recessed towards the liquid chamber 12 to form a negative pressure source mounting position. The top of the negative pressure source mounting position corresponds to the reserved area of ​​the hanging ear 23. The reserved area of ​​the hanging ear 23 is also provided with a third hole 7 that connects the airflow cavity 13 and the negative pressure source mounting position. The HEPA groove, the airflow cavity 13, and the third hole 7 constitute the second conveying channel.

[0048] Understandably, the first sealing ring 61 is used to seal the solid material cavity 11, and the second sealing ring 62 serves to seal the entire water tank 1.

[0049] It should be noted that the HEPA 5 includes a corresponding dustproof side and an air outlet side. The dustproof side corresponds to the liquid chamber 12, and the air outlet side corresponds to the airflow chamber 13. The air outlet side is connected to the negative pressure source after communicating with the third hole 7 in the airflow chamber 13. It should also be noted that the top of the negative pressure source mounting position is provided with a fourth hole, which is connected to the third hole 7 through the second conveying pipe 4, facilitating the installation of the negative pressure source air inlet.

[0050] The overall concept provided in this application is that a first conveying pipe 3 extending into the solid material chamber 11 is provided through the bottom of the water tank 1. Under the action of negative pressure, air and waste material are introduced through the first conveying pipe 3. The waste material undergoes solid-liquid separation through the filter surface 21 of the filter screen 2. The airflow passes through the filter surface 21 and through the space of the liquid material chamber 12 before being discharged through the second conveying channel. The negative pressure generated by the negative pressure source not only plays the role of sucking up the waste material, but also accelerates the solid-liquid separation effect. The filtered solid waste is easier to dry, which can reduce the water content in the solid and facilitate the subsequent treatment of solid waste.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
