Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a sewage tank and a floor scrubber. Background Art

[0002] With the changes in the existing social environment and people's pursuit of health, as well as the improvement of living standards, people have higher and higher requirements for their family living environment. In order to better clean the dirty floor and ensure the cleaning quality, the market has seen the emergence of floor washing machines that integrate the functions of washing, mopping and vacuuming. They are effective in cleaning and easy to use.

[0003] When cleaning the floor, a general floor scrubber will suck sewage, solid waste and external gas on the floor into the floor scrubber through the air intake channel. Therefore, solids, gases and liquids need to be separated while cleaning the floor to avoid blockage of the air intake channel or other components of the floor scrubber.

[0004] However, conventional floor scrubbers do not fully separate solids, gases, and liquids. The airflow carries some solid and liquid waste, causing a large amount of waste to accumulate, affecting the suction power of the entire machine. In addition, when dirt accumulates, it needs to be cleaned after each use, resulting in a poor user experience. Summary of the Invention

Sewage in the sewage extraction channel, driven by airflow, passes through the notch into the separation channel and rotates along the separation channel, separating solid matter from non-solid matter in the sewage. In this manner, sewage in the sewage extraction channel, after being driven out of the sewage channel by airflow, enters the separation channel through the notch, where it separates gas, solids, and / or liquids. When liquid is present in the sewage, solids, liquids, and gases are separated. When liquid is absent, solids and gases are separated. This prevents gas-carrying solids and liquid debris from clogging the airflow channel and prevents solids from being difficult to clean in liquids. This achieves efficient sewage separation within the sewage tank and improves user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See Figures 1 to 4One embodiment of the present application provides a sewage tank 100, comprising a housing 10 and a filter assembly 20. The housing 10 has a sewage extraction channel 12 for extracting sewage into the sewage tank 100. The filter assembly 20 is assembled within the housing 10 and comprises a main body 21 and a spiral blade 22 that rotates along the outer circumference of the main body 21 and extends axially along the main body 21. The spiral blade 22, the main body 21, and the housing 10 together form a separation channel. A notch 211 is defined in the circumferential sidewall of the main body 21. The sewage extraction channel 12 communicates with the separation channel through the notch 211. Sewage in the sewage extraction channel 12, driven by airflow, enters the separation channel through the notch 211 and rotates along the separation channel, separating solid matter from non-solid matter. Thus, after being driven out of the sewage channel by the airflow, the sewage in the sewage extraction channel 12 enters the separation channel through the notch 211, achieving separation of gas, solids, and / or liquids within the separation channel. This avoids the blockage of the air flow channel by solid and liquid garbage carried by gas, and also avoids the phenomenon that solids contained in liquid are difficult to clean, thereby achieving the separation of sewage in the sewage tank 100 and improving the user experience.

[0042] Specifically, the sewage carried by the airflow may contain both solids and liquids, or may consist solely of solids. When the sewage contains both solids and liquids, the airflow drives the sewage to rotate within the separation channel, enabling separation of solids, liquids, and gases. When the sewage contains no liquid, the airflow drives the sewage to rotate within the separation channel, enabling separation of solids and gases. This prevents the airflow channel from being clogged by solids or liquid waste carried by the gas, and also avoids the difficulty of cleaning solids contained in the liquid.

[0043] In one embodiment, see Figure 3 and Figure 4 One end of the spiral blade 22 is connected to the outer wall of the main body 21, and the other end extends toward the inner wall of the housing 10. A certain distance is reserved between at least part of the spiral blade 22 and the inner wall of the housing 10. This distance allows the liquid in the sewage in the separation channel to pass through. In this way, when the airflow drives the sewage to flow in the separation channel, the liquid will flow down from the distance due to its fluidity and gravity and be stored in the housing 10. The solids in the raw sewage are not fluid and will be retained on the surface of the spiral blade 22 when flowing with the airflow in the separation channel. After the airflow completes its flow in the separation channel, it can leave the separation channel through various gaps or other reserved structures, thereby achieving the separation operation of solid matter, gaseous matter, and liquid matter in the sewage.

[0044] It can be understood that after separation, the solid waste remains in the separation channel and adheres to the surface of the spiral blade 22. The user only needs to clean the filter component 20 without touching the waste alone, so it will not cause pollution to hands, clothes, etc., and will not increase the amount of additional cleaning, which greatly improves the user's satisfaction and experience.

[0045] Specifically, due to the spiral arrangement of the spiral blades 22, the separation flow path of the sewage is lengthened, that is, the separation flow path has a certain length, thereby ensuring that various substances in the sewage can be fully and effectively separated.

[0046] In one embodiment, the main body 21 has a ventilation cavity (not shown) that communicates with the exterior of the housing 10. The ventilation cavity is independent of the notch 211, and the main body 21 allows the gas within the separation channel to pass through and enter the ventilation cavity. The independence of the ventilation cavity and the notch 211 means that the airflow and sewage from the sewage extraction channel 12 cannot directly enter the ventilation cavity through the notch 211. Instead, the airflow and sewage must flow through the separation channel to separate the gas, solid, and / or liquid before entering the ventilation cavity.

[0047] Specifically, the airflow and sewage from the sewage extraction channel 12 enter the separation channel through the notch 211. During circulation within the separation channel, the main body 21 allows the gas within the separation channel to pass through and enter the air vent cavity. Since the air vent cavity is connected to the outside of the housing 10, the airflow can directly exit the sewage tank 100 through the air vent cavity. However, the main body 21 does not allow solid matter and gaseous matter to pass through. Therefore, when the airflow passes through the main body 21, solids and liquids are impacted by the outer surface of the main body 21, further separating the gaseous matter from the non-gaseous matter, and then continuing the solid-liquid separation operation within the separation channel.

[0048] Specifically, see Figure 3 and Figure 4 The main body 21 is provided with a plurality of through holes 214 leading from the outer surface of the circumference to the air-discharging cavity. The through holes 214 only allow gas to pass through, so that the gas enters the air-discharging cavity through the through holes 214 and the main body 21.

[0049] In some other embodiments, the main body 21 may also be a material that is only permeable in one direction (from the separation flow channel to the air vent chamber), thereby achieving separation of gas and solid-liquid. It is not limited to the solution of opening the through hole 214 in the above embodiment, and this application does not limit it here.

[0050] In one embodiment, see Figure 4The filter assembly 20 also includes a barrier 24, which is assembled within the main body 21 and divides the main body 21 into an air-discharging chamber and a connecting chamber 213. The connecting chamber 213 communicates with the sewage extraction channel 12 and is connected to the separation channel via a notch 211. When sewage in the sewage extraction channel 12 enters the connecting chamber 213 under the influence of airflow, it continues to flow and strikes the barrier 24, causing it to be redirected. The redirected airflow and sewage then enter the separation channel through the notch 211. After the separation process is completed within the separation channel, gas enters the air-discharging chamber and is discharged outside the sewage tank 100. Solids remain in the separation channel and adhere to the spiral blades 22. Liquid flows downward through the gap between the spiral blades 22 and the tank 10, becoming stored within the tank 10.

[0051] Further, see Figure 2 The sewage extraction channel 12 has an outlet 121 in the box body 10, and the blocking member 24 is opened in an arc shape, and the arc concave surface of the blocking member 24 is arranged to face the outlet 121; wherein the orthographic projection of the blocking member 24 toward the plane where the outlet 121 is located completely covers the outlet 121, so that the sewage flowing out of the outlet 121 can all hit the arc concave surface of the blocking member 24 under the drive of the airflow, and flow through the notch 211 to the spiral blade 22 under the guidance of the arc surface, ensuring that all sewage is separated.

[0052] In one embodiment, see Figure 1 The sewage tank 100 also has a first space 11 and a pouring spout 13 connected to the first space 11. The sewage extraction channel 12 is provided in the first space 11. The liquid that falls into the tank body 10 through the filter assembly 20 is stored in the first space 11. The filter assembly 20 is mounted in the pouring spout 13. In this way, the gas entering the air vent cavity can be discharged from the sewage tank 100 through the side of the pouring spout 13, thereby completing the complete flow of air. When the sewage in the first space 11 needs to be poured out, the filter assembly 20 can be removed to open the pouring spout 13. By holding the sewage tank 100 and tilting it, the sewage in the first space 11 can be discharged from the pouring spout 13.

[0053] Through the filtering effect of the filter assembly 20, a good separation effect with fewer parts is achieved. At the same time, the filter assembly 20 is easy to rinse, and there is no need to purchase additional disposable accessories and consumables for filtering, which greatly reduces production costs and achieves recycling.

[0054] In one embodiment, see Figure 1The sewage tank 100 also includes a sealing ring 30, which is assembled between the filter assembly 20 and the box wall of the box body 10 facing the first space 11, and is used to ensure the sealing of the assembly of the filter assembly 20 and the box body 10, and to ensure that there is sufficient suction in the sewage pumping channel 12 of the sewage tank 100 to suck sewage into the sewage tank 100.

[0055] Specifically, see Figure 1 and Figure 3 The filter assembly 20 also includes an assembly portion 23, which is connected to the side of the main body 21 away from the sewage channel. The sealing ring 30 is assembled between the assembly portion 23 and the box body 10. The assembly portion 23 has a through hole 231 that is connected to the air vent cavity. The gas in the air vent cavity can be discharged from the sewage tank 100 through the through hole 231, and the suction force when absorbing water through the sewage pumping channel 12 can also be transmitted to the sewage discharge channel 12 through the through hole 231.

[0056] In one embodiment, see Figure 1 The sewage tank 100 also includes an electrode assembly 40, which includes a first electrode 41 and a second electrode 42. The first electrode 41 and the second electrode 42 are both mounted on the mounting portion 23 and at least partially inserted into the first space 11. When the sewage in the first space 11 rises to at least partially submerge the first and second electrodes 41 and 42, the first and second electrodes 41 and 42 are electrically conductive. When the first and second electrodes 41 and 42 are electrically conductive, it indicates that the water level in the first space 11 is too high, reminding the operator to empty the sewage in the sewage tank 100. When the sewage in the first space 11 is too low, the first and second electrodes 41 and 42 are both away from the water surface, indicating that the sewage tank 100 has sufficient capacity and can continue to perform sewage removal work.

[0057] Furthermore, the first electrode 41 and the second electrode 42 are assembled on the assembly part 23 at intervals. The electrode assembly 40 itself is made of a micro-conductive material. The electrode assembly 40 is inserted into the box body 10 so as to make contact inside the box body 10, thereby detecting the sewage capacity in the first space 11.

[0058] In one embodiment, see Figure 1 The sewage tank 100 further includes a sealing gasket 60 , which is assembled on the assembly portion 23 to seal the through opening 231 , thereby sealing the air vent cavity to ensure that the air intake and exhaust ports of the sewage tank 100 are sealed.

[0059] According to another aspect of the present application, participation Figure 5 and Figure 6A floor scrubber 600 is also provided, comprising a main component 200 and a sewage tank 100 provided in any of the above embodiments. The main component 200 has a first mounting position 210, and the sewage tank 100 is mounted on the first mounting position 210. Thus, when the floor scrubber 600 is cleaning the floor, the sewage from the floor can be drawn into the sewage tank 100 through the sewage extraction channel 12, and solids, gases, and / or liquids are fully separated within the sewage tank 100, thereby preventing the problem of gas-carrying waste flying around and causing blockage that could affect the overall suction power of the floor scrubber 600, while also improving the user experience.

[0060] Specifically, the sewage tank 100 further includes a fixing member 50, which includes an elastic member 51 and an operating portion 52. The operating portion 52 is movably connected to a side of the filter assembly 20 facing away from the first space 11, and the elastic member 51 is assembled between the operating portion 52 and the filter assembly 20. The operating portion 52 has a protruding fixing portion 521. When the sewage tank 100 needs to be removed from the first mounting position 210, pressing the operating portion 52 causes the elastic member 51 to elastically deform until the fixing portion 521 is released from a corresponding fixing groove (not shown) provided in the main component 200, thereby achieving a detachable connection between the sewage tank 100 and the main component 200.

[0061] In one embodiment, a floor scrubber 600 further includes a floor brush assembly 300 and a power unit 400, both of which are assembled on the main unit 200. The floor brush assembly 300 has an air intake channel that communicates with the sewage extraction channel 12. The power unit 400 provides power to draw sewage from the air intake channel into the sewage extraction channel 12. Thus, during use, the power unit 400 provides suction force, drawing sewage from the floor into the air intake channel of the floor brush assembly 300. The sewage then flows along the airflow into the sewage extraction channel 12, and then into the sewage tank 100, achieving a comprehensive cleansing of the floor.

[0062] Furthermore, the power component 400 is provided with an exhaust hole or an exhaust channel connected to the first space 11 of the sewage tank 100. After leaving the sewage tank 100, the continuously upward airflow is discharged into the air through the exhaust hole or the exhaust channel, thereby completing the sewage extraction process of the sewage tank 100.

[0063] In one embodiment, the floor scrubber 600 further includes a clean water tank 500 , which is mounted on the main component 200 and has a water supply channel connected to the floor brush assembly 300 ; the clean water tank 500 sprays water to the outside through the water supply channel, thereby mopping and washing the floor.

[0064] Specifically, the main component 200 also has a second mounting position 220 and a third mounting position 230. The clean water tank 500 is assembled on the second mounting position 220, and the power component 400 is assembled on the third mounting position 230. In this way, the clean water tank 500, the sewage tank 100, the power component 400, and the floor brush assembly 300 are all assembled and connected with the main component 200, thereby integrating to form an overall floor scrubber 600.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
