The water tank comprises a tank body, an inside of which is formed with a sewage cavity, the sewage cavity having an outlet at an upper portion; and a wave breaker plate arranged in the sewage cavity, the wave breaker plate being arranged to extend in a second direction, and a plurality of flow holes being arranged on the wave breaker plate; wherein the second direction is non-parallel to the first direction, so that the wave breaker plate can block fluid flowing in the first direction and force the fluid to pass through the flow holes. The surge formed by the shaking of the sewage liquid surface in the sewage cavity can be blocked by the wave breaker plate and forced to pass through the flow holes, breaking the large-scale surge into small streams, effectively reducing the degree of fluctuation of the liquid surface, preventing the water liquid from overflowing from the outlet of the sewage cavity into the exhaust passage, and avoiding water entering the motor of the cleaning device. The flow holes on the wave breaker plate can allow air to pass normally, without affecting the water-air separation in the sewage cavity.

[0038] To achieve the above objectives, a third aspect of this application provides a cleaning device including the floor brush assembly described in any of the above embodiments.

[0039] The advantages of this application, which differ from existing technologies, are:

[0040] The wastewater chamber of the water tank in this application is equipped with a wave-damping plate extending in a second direction. When the water tank is driven to move in a first direction, the surge formed by the sloshing of the wastewater surface in the wastewater chamber and traveling in the first direction can be blocked by the wave-damping plate and forced to pass through the flow holes, breaking the large-scale surge into small streams, effectively attenuating the degree of surface fluctuation, suppressing violent surface fluctuations, preventing water from overflowing from the outlet of the wastewater chamber into the exhaust channel, and avoiding water entering the motor of the cleaning equipment; in addition, the flow holes on the wave-damping plate allow airflow to pass normally without affecting the water-air separation in the wastewater chamber.

[0041] The water tank of this application includes wave-damping plates arranged on both sides of the inlet. When the water enters the sewage chamber through the inlet, it can fall directly into the bottom of the lower chamber, avoiding the wave-damping plates from blocking the inlet of the sewage chamber. The wave-damping plates on both sides limit the inlet area, realizing the flow guiding function, preventing the sewage from directly impacting the side chamber wall when it flows into the chamber at high speed through the inlet, suppressing the surge generated during the inlet, reducing the interference of the inlet process on the internal flow of the chamber, and thus preventing the water from overflowing into the exhaust channel and causing water to enter the motor.

[0042] The water tank of this application includes multiple wave-damping perforated plates arranged at intervals, which can force the surge to repeatedly turn and dissipate energy between the wave-damping perforated plates, thereby achieving the purpose of further suppressing the surge intensity.

[0043] In this application, the area of ​​the wave-damping perforated plate located in the middle of the water tank in the first direction is larger than the area of ​​the wave-damping perforated plates located on both sides. The large area wave-damping perforated plate located in the middle is directly facing the impact of large surges, which can break the large surges into small streams of liquid. The small area wave-damping perforated plates located on the sides block small-intensity surges and the broken small streams of liquid, which can effectively suppress the fluctuation of the liquid surface in the sewage chamber. The surge suppression effect is not affected while setting small area wave-damping perforated plates, which reduces costs and reduces the space occupied by the sewage chamber.

[0044] The water tank in this application also includes a wave-damping plate located next to the outlet. The wave-damping plate can effectively block water surges into the outlet, further avoiding the risk of water entering the equipment and improving equipment safety. The wave-damping perforated plate is arranged on the bottom surface of the wave-damping plate. The two can work together to block water from entering the outlet, forming an integrated wave-damping protection structure. Attached Figure Description

[0058] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0059] The floor cleaning attachment of the cleaning equipment has a built-in wastewater tank. During operation, negative pressure is used to suck the dirt and liquid from the surface to be cleaned into the floor cleaning attachment, and water and air separation is used to retain the dirt and liquid in the wastewater tank.

[0060] When the floor cleaning attachment is in operation, it needs to move back and forth on the surface to be cleaned. The sewage in the wastewater tank will shake and generate waves as the attachment moves. These waves may flow into the exhaust channel, causing water to enter and damage the fan of the cleaning equipment.

[0061] To address the aforementioned issues, the applicant has developed a novel water tank that effectively suppresses surge intensity. When applied to the floor brush mechanism of cleaning equipment, it effectively suppresses severe fluctuations in the water level within the tank during the brush's movement, preventing high-level turbulent water from rushing into the exhaust channel and causing water ingress into the motor.

[0062] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of one embodiment of the water tank in this application. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the AA plane.

[0063] like Figure 1 and Figure 2 As shown, the water tank 1 includes a tank body 10 with a sewage chamber 11 formed inside, the sewage chamber 11 having an outlet 110 located at the top, and the water tank 1 can be driven to move along a first direction y.

[0064] Wherein, the first direction y is the direction of travel of the water tank 1 during cleaning. In one embodiment, when the water tank 1 is applied to the floor brush mechanism, the user can control the floor brush mechanism to move back and forth along the first direction y on the surface to be cleaned by hand, so as to clean the surface to be cleaned; in other embodiments, when the water tank 1 is applied to autonomous mobile cleaning equipment such as a sweeping robot, the first direction y is the autonomous travel direction of the cleaning equipment.

[0065] A wave-damping plate 12 is arranged in the sewage chamber 11. The wave-damping plate 12 extends along the second direction x and has multiple flow holes 120 arranged on it. The second direction x is not parallel to the first direction y.

[0066] Based on the above scheme, when the water tank 1 is driven to move along the first direction y, the surge formed by the sloshing of the sewage surface in the sewage chamber 11 along the first direction y can be blocked by the anti-wave plate 12 because the second direction x is not parallel to the first direction y. The surge is forced to pass through the flow hole 120, thereby breaking the large-scale surge into small streams, effectively attenuating the degree of fluctuation of the liquid surface, suppressing the violent fluctuation of the liquid surface, preventing water from overflowing from the outlet 110 of the sewage chamber 11 into the exhaust channel, and avoiding water entering the motor of the cleaning equipment. In addition, the flow hole 120 on the anti-wave plate 12 allows the airflow to pass normally without affecting the water-air separation in the sewage chamber 11.

[0067] For further details, please refer to Figure 3 , Figure 3 yes Figure 2 A schematic diagram of the cross-sectional structure of the BB plane. (See diagram below.) Figure 2 and Figure 3 As shown, the second direction x is perpendicular to the first direction y, that is, the wave-damping plate 12 is set perpendicular to the direction of travel of the water tank 1, and the wave-damping plate 12 is arranged vertically, that is, the wave-damping plate 12 is set parallel to the height direction z of the water tank 1.

[0068] Based on the above scheme, the surface of the wave-blocking perforated plate 12 is perpendicular to the main impact direction of the surge. Compared with the wave-blocking perforated plate 12 arranged at an angle, the blocking area of ​​the wave-blocking perforated plate 12 can be maximized, the surge breaking efficiency can be improved, and the liquid storage space occupied by the wave-blocking perforated plate 12 can be minimized, thus reducing the volume of the water tank 1.

[0069] In other embodiments, the extension direction and tilt angle of the anti-wave plate 12 can be adjusted according to the actual application scenario requirements. For example, when the water tank 1 is applied to a floor brush mechanism with multiple different travel directions, such as a floor brush mechanism equipped with casters, multiple anti-wave plates 12 with different extension directions can be set to block surges in different travel directions, etc., all of which can achieve the effect of this embodiment.

[0070] Furthermore, such as Figure 2 As shown, in this embodiment, the sewage chamber 11 has an inlet 111 arranged on one side of the chamber wall along the first direction y. The inlet 111 is used to supply water into the sewage chamber 11. The water tank 1 includes wave-damping plates 12 arranged on both sides of the inlet 111 along the second direction x.

[0071] Based on the above scheme, when the water enters the sewage chamber 11 through the inlet 111, it can fall directly into the bottom of the lower chamber, avoiding the baffle plate 12 from blocking the inlet of the sewage chamber 11. In addition, the baffle plates 12 located on both sides of the inlet 111 define the inlet area, realizing the guiding effect, preventing the sewage from directly impacting the side chamber wall when it flows into the chamber at high speed through the inlet 111, suppressing the surge generated during the inlet, reducing the interference of the inlet process on the internal flow of the chamber, and thus preventing the water from overflowing into the exhaust channel and causing water to enter the motor.

[0072] In other embodiments, based on actual needs, the wave-damping plate 12 can also be arranged along the second direction x on one side of the inlet 111, or an area for avoiding the inlet 111 can also be arranged on the wave-damping plate 12. For example, please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a cross-sectional structural schematic diagram of another embodiment of the water tank in this application, as shown below. Figure 4 As shown, the wave-blocking plate 12 has a first hollow area 121 arranged on it to avoid the inlet 111, which also achieves the effect of this embodiment to a certain extent.

[0073] Furthermore, such as Figure 3 As shown, in this embodiment, the water tank 1 includes a plurality of anti-wave plate 12 spaced apart along the first direction y.

[0074] Based on the above scheme, multiple anti-surge perforated plates 12 spaced apart along the first direction y can force the surge to repeatedly turn and dissipate energy between the anti-surge perforated plates 12, thereby achieving the purpose of further suppressing the surge intensity.

[0075] Specifically, in this embodiment, the water tank 1 includes two sets of anti-wave perforated plates 12 symmetrically arranged on both sides of the inlet 111 along the second direction x. Each set includes three anti-wave perforated plates 12 spaced apart along the first direction y. In other embodiments, each set of anti-wave perforated plates 12 may also include other numbers of anti-wave perforated plates 12, such as two, four, five, etc., which can be adjusted according to actual needs.

[0076] Furthermore, such as Figure 3 As shown, in this embodiment, the area of ​​the wave-damping perforated plate 12 located in the middle of the first direction y is larger than the area of ​​the wave-damping perforated plates 12 located on both sides.

[0077] Based on the above scheme, when the water tank 1 moves, the liquid surface surge amplitude in the central area of ​​the sewage chamber 11 is the largest. The large-area anti-surge plate 12 located in the middle is directly facing the impact of the large surge, which can break the large surge into small streams of liquid. The small-area anti-surge plate 12 located on the side blocks the small-intensity surge and the broken small streams of liquid, which can effectively suppress the liquid surface fluctuation in the sewage chamber 11. The surge suppression effect is not affected while setting the small-area anti-surge plate 12, which reduces the cost and reduces the occupation of the liquid storage space of the sewage chamber 11.

[0078] Of course, in other embodiments, the area of ​​the plurality of anti-surge perforated plates 12 arranged at intervals along the first direction y can also be the same, which can also achieve the purpose of effectively suppressing surges.

[0079] The arrangement and structure of the wave-damping perforated plate 12 are described in detail below, such as... Figure 2 and Figure 3 As shown, in this embodiment, the housing 10 includes a shell 100 with a top opening and a cover 101 arranged at the opening. The outlet 110 of the sewage chamber 11 is arranged on the cover 101, and the wave-damping plate 12 is arranged on the cover 101.

[0080] The outlet 110 is used to allow the airflow that has undergone water-liquid separation to leave the sewage chamber 11 and enter the exhaust channel.

[0081] Based on the above solution, on the one hand, the anti-surge plate 12 can be disassembled and installed simultaneously when the cover 101 is disassembled and installed, which facilitates the disassembly, installation and maintenance of the anti-surge plate 12; on the other hand, the anti-surge plate 12 extends downward from the lower surface of the cover 101, and the extension length of the anti-surge plate 12 can be controlled according to the height of the sewage chamber 11 to ensure the suppression effect on surges; at the same time, the anti-surge plate 12 and the outlet 110 are both arranged on the cover 101, and the anti-surge plate 12 located next to the outlet 110 can effectively prevent liquid splashing into the interior of the outlet 110, further preventing water from entering the exhaust channel.

[0082] Furthermore, such as Figure 2 As shown, in this embodiment, the sewage chamber 11 also includes an air outlet area 112 located on the air inlet side of the outlet 110. The airflow can enter the outlet 1101 through the air outlet area 112 and be discharged from the sewage chamber 11.

[0083] The wave-damping plate 12 has a second perforated area 127 for avoiding the air outlet area 112 next to the outlet 110.

[0084] Based on the above scheme, relying on the design of the second hollow area 127 to avoid the air outlet area 112, the airflow can smoothly pass through the air outlet area 112 along the first direction y and flow into the outlet 110, avoiding the obstruction of the airflow by the anti-wave plate 12, making the airflow velocity and air volume distribution of the entire area of ​​the outlet 110 more uniform, ensuring the stable and consistent water-air separation effect inside the sewage chamber 11, and avoiding water accumulation and airflow turbulence problems caused by local airflow obstruction.

[0085] For further details, please refer to Figure 5 , Figure 5 This is a structural schematic diagram of one embodiment of the cover of this application. For example... Figure 5As shown, in this embodiment, the water tank 1 also includes a wave-damping plate 13 that is disposed below the outlet 110 along the extension direction y of the outlet 110. The orthogonal projection of the wave-damping plate 13 in the height direction z of the sewage chamber 11 covers the outlet 110.

[0086] Based on the above scheme, the wave-damping plate 13 forms a continuous full-area shield below the outlet 110, which can directly block the vertical surge below the outlet 110 when the water tank is driven to move, block the path of the surge directly into the outlet 110, reduce the risk of high-level turbulent water entering the outlet 110, further avoid the risk of water entering the equipment, and improve the safety of the equipment.

[0087] Furthermore, in this embodiment, the wave-damping perforated plate 12 is arranged on the bottom surface of the wave-damping plate 13, and the two can work together to prevent water from entering the outlet 110, forming an integrated wave-damping protection structure.

[0088] Specifically, such as Figure 3 As shown, in this embodiment, the wave-damping plate 13 includes a main baffle section 130 and a side baffle section 131 located at the end of the main baffle section 130. The main baffle section 130 extends from one side of the sewage chamber 11 along the extending direction y of the outlet 110 to the other side to cover the area below the outlet 110. The side baffle section 131 extends from the end of the main baffle section 130 along the height direction z of the sewage chamber 11 to the top wall of the sewage chamber 11 to cover the side of the outlet 110.

[0089] Based on the above scheme, the main baffle section 130 extends across the entire sewage chamber 11 along the direction of the outlet 110, covering the entire area directly below the outlet 110 and blocking the surge impact in the vertical upward and front-back directions; the side baffle section 131 extends from both ends of the main baffle section 130 along the height direction z to the top wall of the sewage chamber 11, completely covering the lateral gap between the outlet 110 and the side wall of the sewage chamber 11, which can effectively intercept the small streams of liquid and diffused water mist splashed to both sides after being broken by the wave-damping plate 12, thus achieving all-round protection for the outlet 110.

[0090] Furthermore, such as Figure 3 As shown, in this embodiment, in the height direction z of the sewage chamber 11, the main baffle section 130 and the outlet 110 are spaced apart to form a first gap 15 between them for the water supply liquid to return to the sewage chamber; in the first direction y, the side baffle section 131 and the outlet 110 are spaced apart to form a second gap 16 between them for the air supply to pass through.

[0091] Based on the above scheme, the first gap 15 reserved between the main baffle section 130 and the outlet 110 allows water splashed on the surface of the wave-damping plate 13 to flow back to the bottom of the sewage chamber 11 under the action of airflow, preventing water from accumulating on the surface of the wave-damping plate 13 and being drawn into the outlet by the high-speed airflow. At the same time, the first gap 15 and the second gap 16 reserved between the side baffle section 131 and the outlet 110 form a continuous airflow path, allowing the airflow on the side of the outlet 110 away from the inlet 111 to smoothly flow into the outlet through the first gap 15 and the second gap 16, effectively increasing the total airflow cross-sectional area, avoiding negative pressure loss caused by the wave-damping plate 13, and thus achieving a reliable anti-wave function without affecting the water-air separation efficiency of the sewage chamber and the suction stability of the equipment.

[0092] Furthermore, such as Figure 2 As shown, in this embodiment, the cover 101 includes a cover plate 1011 and an inner cover 1012 disposed on the inner surface of the cover plate 1011. The cover plate 1011 and the inner cover 1012 surround to form an exhaust channel 1013. The inner cover 1012 includes an inner section 10121 located in the sewage chamber 11, and an outlet 110 is disposed on the side of the inner section 10121 facing the inlet 111.

[0093] Based on the above scheme, the outlet 110 is located on the side of the cavity section 10121 facing the inlet 111, so that the vertically upward main surge cannot directly rush into the outlet 110. It must first impact the bottom surface of the wave-damping plate 13 before contacting the opening of the outlet 110, which greatly reduces the probability of the surge directly entering the exhaust channel 1013. At the same time, the cover plate 1011 and the inner cover 1012 are integrated to form the exhaust channel 1013, eliminating the need for additional external pipelines, simplifying the overall structure of the water tank 1, and improving the assembly sealing and reliability.

[0094] For further details, please refer to Figure 2 and 6 , Figure 6 yes Figure 2 A magnified view of part A in the diagram, as shown below. Figure 6 As shown, in the height direction z of the sewage chamber 11, the orthogonal projection of the wave-damping plate 13 includes a first part 132 that overlaps with the chamber section 10121, and a second part 133 located on the side of the first part 132 near the inlet 111.

[0095] Based on the above scheme, the first part 132 can block the surge below the outlet 110 from entering the outlet 110, and the second part 133 extends from the first part 132 towards the inlet 111, which can effectively block the oblique surge from entering the outlet 110. The two work together to effectively block the channel for the surge to enter the outlet 110, further avoiding the risk of water entering the equipment and improving the safety of the equipment.

[0096] Furthermore, in this embodiment, the bottom surface of the cavity section 10121 of the inner cover 1012 is formed with a guide surface 10123 corresponding to the position of the outlet 110, and the guide surface 10123 is inclined downward in the direction close to the inlet 111.

[0097] Based on the above scheme, the inclined guide surface 10123 can, on the one hand, allow water splashed on the bottom surface of the cavity section 10121, the inner edge of the outlet 110, and a small amount of water that has seeped into the outlet 110 to automatically flow downward along the guide surface 10123 under the action of gravity, and directly flow back to the upper surface of the wave-damping plate 13 below the outlet 110 or the bottom of the sewage chamber 11, effectively preventing water from being carried into the exhaust channel 1013 by the airflow. On the other hand, the guide surface 10123 can guide the airflow flowing from the side of the outlet 110 away from the inlet 111 through the first gap 15 toward the wave-damping plate 13, so that the water on the upper surface of the wave-damping plate 13 can flow back to the bottom of the sewage chamber 11 under the action of the airflow, avoiding the risk of water seeping into the outlet and improving equipment safety.

[0098] The structure of the wave-damping perforated plate 12 on the wave-damping plate 13 is described in detail below, such as Figure 5 As shown, in this embodiment, the water tank 1 includes a first wave-damping perforated plate 12a located in the middle of the wave-damping plate 13, and a second wave-damping perforated plate 12b symmetrically arranged on both sides of the first wave-damping perforated plate 12a along the first direction y.

[0099] The second wave-blocking plate 12b extends downward from the bottom surface of the wave-blocking plate 13 along the height direction z of the sewage chamber 11 to block the surge in the area below the wave-blocking plate 13.

[0100] The first wave-damping plate 12a includes a main wave-damping section 122, a first connecting section 123, and a second connecting section 124. The first connecting section 123 connects one end of the main wave-damping section 122 in the second direction x to the wave-damping plate 13, and the second connecting section 124 connects the other end of the main wave-damping section 122 in the second direction x to the top wall of the sewage chamber 11. The distance between the second wave-damping plate 12b and the bottom of the sewage chamber 11 is greater than the distance between the first wave-damping plate 12a and the bottom of the sewage chamber 11.

[0101] Based on the above scheme, the first wave-damping plate 12a extends from below the outlet 110 toward the inlet 111, covering most of the cross-section of the sewage chamber 11. The second wave-damping plate 12b only covers the area directly below the outlet 110. When the surge travels along the first direction y, it is first blocked by the second wave-damping plates 12b on both sides, breaking the large surge below the outlet 110 into small streams, suppressing the surge intensity below the outlet 110, and preventing the surge from splashing into the outlet 110. The large surges in other areas and the small streams broken by the second wave-damping plates 12b are further suppressed by the large-sized first wave-damping plate 12a, thus effectively preventing water from entering the outlet 110.

[0102] Meanwhile, the distance between the bottom end of the second wave-damping plate 12b and the bottom of the sewage chamber 11 is greater than the distance between the first wave-damping plate 12a and the bottom of the sewage chamber 11. The second wave-damping plate 12b is only used for surge suppression under high water levels. Under low water levels, the risk of water splashing into the outlet 110 is low, and it is blocked and suppressed only by the first wave-damping plate 12a. This helps to reduce the height of the second wave-damping plate 12b, reduce costs and the volume occupied by the sewage chamber 11.

[0103] Furthermore, in this embodiment, the second wave-damping plate 12b includes an extension section 125 and a widening section 126 disposed along the direction toward the bottom of the sewage chamber 11. The extension length of the widening section 126 in the second direction x is greater than the extension length of the extension section 125 in the second direction x.

[0104] Based on the above scheme, the widened section 126 at the end extends beyond the coverage of the wave-blocking plate 13 in the second direction x, effectively blocking and suppressing the surge in the areas on both sides of the wave-blocking plate 13, and achieving wave protection without dead angles around the outlet 110.

[0105] It should be noted that in other embodiments, the wave-blocking perforated plates 12 of the wave-blocking plate 13 can also adopt other arrangements. For example, multiple first wave-blocking perforated plates 12a can be arranged at intervals on the wave-blocking plate 13, and each first wave-blocking perforated plate 12a is fixed to the wave-blocking plate 13 and the inner wall of the cover 101. Alternatively, multiple second wave-blocking perforated plates 12b can be arranged at intervals on the wave-blocking plate 13. Or, a second wave-blocking perforated plate 12b located in the middle and first wave-blocking perforated plates 12a located on both sides of the second wave-blocking perforated plate 12b can be arranged on the wave-blocking plate 13, etc. These can be adjusted according to actual needs, and all of them can suppress the entry of high-level turbulent water into the outlet 110 to a certain extent, so as to avoid damage to the equipment motor.

[0106] Furthermore, such as Figure 2 As shown, in this embodiment, the inlet 111 is located in the middle of the second direction x of the sewage chamber 11, and the outlet 110 is arranged at the top of the two side walls of the sewage chamber 11 in the second direction x.

[0107] Based on the above scheme, the airflow path is as follows: Figure 2 As shown by the middle arrow, the airflow enters the sewage chamber 11 through inlet 111 and is split into two streams, moving to opposite sides and exiting at outlet 110 on the chamber wall. This maximizes the airflow path and improves separation efficiency. Simultaneously, the airflow splitting ensures a more uniform and orderly distribution within the chamber, preventing localized turbulence and short-circuit flow. This effectively prolongs the residence time of the impurity-laden airflow within the sewage chamber, further enhancing the separation effect.

[0108] The cover structure of this application is described below; please refer to [link / reference]. Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of one embodiment of the cover of this application from another perspective. Figure 8 This is a cross-sectional structural diagram of one embodiment of the cover of this application.

[0109] like Figure 7 and Figure 8 As shown, in this embodiment, the inner cover 1012 includes a pair of inner sections 10121 located at both ends of the sewage chamber 11 in the second direction x, and an outer section 10122 located outside the sewage chamber 11. The two ends of the outer section 10122 are respectively connected to the corresponding inner sections 10121. The cover plate 1011 and the middle of the outer section 10122 are respectively provided with exhaust ports 10111, so that the airflow flowing into the exhaust channel 1013 through the outlets 110 at both ends converges and is discharged through the exhaust ports 10111.

[0110] Based on the above scheme, the outer section 10122 connecting the two inner sections 10121 is arranged outside the sewage chamber 11, which effectively saves the internal volume of the sewage chamber 11. At the same time, the two airflows entering through the outlets 110 of the two inner sections 10121 flow in opposite directions in the outer section 10122 and converge smoothly in the middle. Then, they are discharged uniformly through the centrally arranged exhaust port 10111, so that the kinetic energy of the two airflows cancels each other out, effectively reducing the impact and eddy current loss when the airflows converge, significantly reducing the negative pressure loss, and ensuring the stability of the suction output of the equipment.

[0111] Furthermore, in this embodiment, the cavity section 10121 extends along the first direction y from one side of the cavity wall near the sewage cavity 11 to the other side of the sewage cavity 11, and the outlet 110 extends from one end of the cavity section 10121 to the other end.

[0112] Based on the above scheme, the inner section 10121 covers most of the area of ​​the sewage chamber 11 in the first direction y, and a second gap 16 is reserved between it and the wave-blocking plate 13. At the same time, the outlet 110 is opened along the entire length of the inner section 10121, so that the airflow from all parts of the sewage chamber 11 in the first direction y can enter the outlet 110 of the corresponding area. With the second gap 16 between the side baffle section 131 of the wave-blocking plate 13 and the outlet 110, the airflow can not only enter from the front of the outlet 110, but also be supplemented from the second gap 16 on the side of the outlet 110. This effectively avoids the generation of local airflow short circuits, eddies and turbulence, and ensures the stability and order of the internal flow field of the sewage chamber 11.

[0113] Furthermore, in this embodiment, the water tank 1 also includes a plurality of guide plates 17 arranged at the outlet 110. The plurality of guide plates 17 are spaced apart along the extension direction of the outlet 110, and the guide plates 17 extend obliquely from the outlet 110 in the direction pointing to the outer cavity section 10122.

[0114] Based on the above scheme, the outlet 110 is arranged along the second direction x towards the inlet 111, while the cavity section 10121 and the outlet 110 are extended along the first direction y. By arranging multiple guide plates 17 at the outlet 110, the airflow can be effectively prevented from being obstructed when turning after entering the outlet 110, ensuring smooth airflow and improving the cleaning effect.

[0115] Furthermore, such as Figure 7 As shown, in this embodiment, the water tank 1 also includes an arc-shaped baffle 18 arranged on the inner wall of the cover plate 1011 and extending from one end of the outlet 110 to the other end. The arc-shaped baffle 18 is arranged to protrude in the direction away from the outlet 110.

[0116] Based on the above scheme, the arc-shaped baffle 18 located on the inner wall of the cover plate 1011 can further prevent water from entering the interior of the outlet 110. Water, solid particles and other materials carried by the airflow can be blocked by the arc-shaped baffle 18 and fall to the bottom of the sewage chamber 11. At the same time, the arc-shaped design can guide the airflow to both sides, which plays a guiding role.

[0117] In this embodiment, the arc-shaped baffle 18 includes a horizontal section 181 and a vertical section 182. The horizontal section 181 extends from the end of the outlet 110 away from the inlet 111 to the wall of the sewage chamber 11 where the inlet 111 is arranged. The vertical section 182 extends downward from the end of the horizontal section 181 near the inlet 111 along the height direction z of the sewage chamber 11.

[0118] Based on the above scheme, the horizontal section 181 completely covers the entire length of the first direction y above the sewage chamber 11, forming a continuous top wall protection zone, which can directly block the high-level turbulent water and splashing droplets generated during the movement of the water tank from hitting the top wall and rebounding towards the outlet, intercepting the droplets outside the outlet 110 area; the vertical section 182 extends downward from the end of the horizontal section 181 near the inlet 111, which can effectively prevent the water attached to the wall of the sewage chamber from being carried into the outlet by the airflow.

[0119] In this embodiment, the vertical section 182 of the arc-shaped baffle 18 is integrated with the wave-damping plate 13, forming a seamless, integral surge protection structure. At the same time, the arc-shaped baffle 18, the wave-damping plate 13, and the side wall of the sewage chamber 11 together form a semi-enclosed protective chamber. This protective chamber only has an opening for airflow on the side facing the inlet 111, which can effectively block surges and splashing droplets from all directions from entering the outlet 110, thereby effectively preventing water from entering the equipment through the outlet 110 and improving the stability of the equipment.

[0120] Furthermore, such as Figure 7 and Figure 8 As shown, in this embodiment, the water tank 1 also includes a grating plate 19 arranged at the outlet 110.

[0121] Based on the above solution, on the one hand, the grating plate 19 can block large solid particles and prevent them from entering the outlet 110, thus avoiding the risk of blockage in the exhaust channel. On the other hand, the grating plate 19 can serve as a second surge protection structure at the outlet 110, which can intercept sewage surges in a secondary manner and further weaken the surge energy. Combined with the function of the guide surface 10123 on the bottom surface of the cavity section 10121, the sewage entering the outlet 110 can flow back into the sewage cavity 11 under the action of the inclined guide surface 10123 after the surge energy is weakened by the grating plate 14, thus preventing water from entering the equipment and causing damage to the motor.

[0122] Specifically, in this embodiment, the grating plate 19 includes a plurality of grating bars 191 spaced apart along the first direction y, and the grating bars 191 extend along the height direction of the sewage chamber 11; in other embodiments, the grating bars 191 of the grating plate 19 may also extend along other directions, and the arrangement direction of the grating bars 191 may also be adjusted accordingly, all of which can achieve the effect of this embodiment to a certain extent.

[0123] Based on the above embodiments, the water tank 1 can effectively suppress the surge intensity of the water inside the sewage chamber 11 when the water tank 1 moves, and prevent the high-level turbulent water from rushing into the exhaust channel through the outlet 110 of the sewage chamber 11. When applied to the floor brush mechanism, it can effectively prevent water from entering the equipment motor during operation and improve the working stability of the equipment.

[0124] This application also provides a floor brush component; please refer to [link / reference]. Figure 9 , Figure 9 This is a schematic diagram of one embodiment of the brush component of this application.

[0125] like Figure 9 As shown, the floor brush assembly includes a roller brush 2 and a water tank 1 in any of the above embodiments.

[0126] When in operation, the floor brush assembly can be connected to a negative pressure source to apply negative pressure to the surface to be cleaned to suck up and clean solid and liquid waste. Solid particles and water generated during cleaning enter the sewage chamber 11 through the inlet 111 to achieve water-liquid-solid separation. The separated water and solid particles remain in the sewage chamber 11, while the airflow enters the cleaning equipment through the outlet 110 of the sewage chamber 11, realizing simultaneous vacuuming and floor cleaning of the surface to be cleaned, greatly improving the cleaning effect.

[0127] The water tank 1 can effectively suppress the surge intensity caused by the sloshing of water in the sewage chamber 11 when the floor brush assembly moves, and prevent water from entering the cleaning equipment through the outlet 110, thus preventing water from entering and damaging the equipment motor.

[0128] This application also provides a cleaning device that includes a floor brush assembly according to any of the above embodiments.

[0129] In one embodiment, the cleaning equipment can be a vacuum cleaner with a floor cleaning attachment; in other embodiments, the cleaning equipment can also be a floor scrubber, both of which can achieve the effect of this embodiment.
