[0021] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0024] The applicant's long-term research has revealed that some sewage tank solutions, in order to detect when the tank is full in different states, employ multiple sets of detection components based on the distribution of sewage within the tank. For example, when the tank is upright, the detection components for upright detection come into contact with the sewage and indicate that the tank is full; when the tank is flat, the detection components for flat detection come into contact with the sewage and indicate that the tank is full.

[0025] Therefore, this type of sewage tank has many detection components and high costs. It not only takes up the usable space of the sewage tank, but also has problems such as difficulty in cleaning, interference between detection components, and high false alarm rate.

[0026] In view of this, in order to solve the above problems caused by multiple detection components and achieve effective water full detection, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of an embodiment of a sewage tank of the present application; Figure 2 It is a schematic cross-sectional structure diagram of an embodiment of a sewage tank of the present application; Figure 3The figure is a schematic cross-sectional view of an embodiment of a sewage tank according to the present application from another perspective. An embodiment of the present application provides a sewage tank 100. The sewage tank 100 includes a housing 110, a detection assembly 120, and a water baffle 130. A chamber 111 for accommodating sewage and a sewage inlet 112 communicating with the chamber 111 are formed within the housing 110. The sewage inlet 112 is configured to communicate with a sewage inlet channel 113. Under the negative pressure of the cleaning device's blower module, sewage and debris enter the chamber 111 through the sewage inlet 112. The chamber 111 has a first side 101 and a second side 102 that are arranged opposite each other. When the sewage tank 100 is in a flat position, the first side 101 is located above the second side 102. The detection assembly 120 is disposed within the chamber 111. When the sewage in the chamber 111 reaches a certain level, the sewage triggers the detection assembly 120 to generate a trigger signal, thereby implementing a full water indication function. The water baffle 130 is disposed in the accommodating chamber 111 and at least partially extends between the detection assembly 120 and the second side 102. The water baffle 130 is used to guide sewage to flow toward the detection assembly 120 to trigger the detection assembly 120.

[0027] As can be seen from the above structure, when the sewage tank 100 is in an upright position, the detection assembly 120 can normally detect the amount of sewage within the sewage tank 100, thereby providing a full-water indication function. When the sewage tank 100 is in a horizontal position, or when the user makes extensive cleaning movements during use, causing the liquid within the accommodating chamber 111 to oscillate, the sewage within the accommodating chamber 111 shifts from being deposited at the bottom in the upright position to flowing toward the cavity wall 102. The sewage that contacts the water baffle 130 changes its direction of movement and surges toward the detection assembly 120. Once the sewage reaches a certain level, the detection assembly 120 is triggered promptly to prevent sewage from surging. When the sewage tank 100 is in an inclined position between the upright and horizontal positions, the water baffle 130 also guides the sewage into contact with the baffle 130, triggering the detection assembly 120 promptly when the sewage is full.

[0028] The sewage tank 100 of the present application is provided with a water baffle 130, which at least partially extends between the detection assembly 120 and the second side 102 of the accommodating chamber 111. This allows the sewage tank 100 to share a single set of detection assemblies 120 to detect when the tank is full in different cleaning positions. This reduces costs, avoids interference between different sets of detection assemblies 120, reduces false alarm rates, and reduces the space occupied by the sewage tank 100. Furthermore, the provision of the water baffle 130 effectively improves the sensitivity of the detection assembly 120 in detecting when the tank is full. Compared to existing solutions that require the sewage tank 100 to increase its overall volume to accommodate fault tolerance for full-water detection, the sewage tank 100 of the present application can reduce its volume, improving its volumetric utilization, given a certain amount of sewage storage. Cleaning equipment utilizing the sewage tank 100 of the present application is more lightweight and flexible.

[0029] Please continue reading Figure 3 and Figure 4 , Figure 4 This is a partial structural diagram of an embodiment of a sewage tank according to the present application, with the tank body and detection electrodes not shown. In some embodiments, the detection assembly 120 includes two probe bodies 121 spaced apart. The two probe bodies 121 emit a water-full signal when they are circulated by sewage, thereby enabling water-full detection. Therefore, the water retaining plate 130 includes two spaced-apart water retaining portions 131, each corresponding to a probe body 121. Each water retaining portion 131 extends at least between the corresponding probe body 121 and the second side 102. The two water retaining portions 131 guide sewage toward the corresponding probe body 121, allowing sewage to flow through both probe bodies 121. This circumstantial flow between the two probe bodies 121 allows accurate water-full detection within the sewage tank 100. By directing sewage toward the corresponding probe body 121 through the two water retaining portions 131, the water-full detection sensitivity of the detection assembly 120 is enhanced, enabling a single set of detection assemblies 120 to detect water-fullness in different cleaning positions within the sewage tank 100.

[0030] Of course, in other embodiments, the detection component 120 can also be other detection methods such as a float liquid level detection sensor, a photoelectric liquid level sensor, an ultrasonic liquid level sensor, etc., and the sewage is guided toward the detection component 120 through the water baffle 130, so that different types of detection components 120 can realize water fullness detection in various cleaning postures of the sewage tank 100.

[0031] To better guide the sewage along the water retaining portion 131 until it contacts the probe body 121, each water retaining portion 131 extends to abut the side of the corresponding probe body 121 facing the second side 102. When the sewage strikes the water retaining portion 131 and rises along the water retaining portion 131 toward the probe body 121, the sewage flow along the water retaining portion 131 toward the probe body 121 is less likely to be interrupted, making it easier for the sewage to contact and conduct the two probe bodies 121, thereby improving the water full detection sensitivity of the detection assembly 120.

[0032] For details, please refer to Figure 3 The probe body 121 includes a probe carrier 1211 and a detection electrode 1212. The detection electrode 1212 is arranged on the probe carrier 1211 and exposed outside the probe carrier 1211. The probe carrier 1211 can support and protect the detection electrode 1212. The width of the side where the water retaining portion 131 abuts the probe body 121 is greater than or equal to the width of the probe carrier 1211; or, the width of the side where the water retaining portion 131 abuts the probe body 121 is greater than or equal to the width of the detection electrode 1212. The width of the water retaining portion 131 is appropriate, which is conducive to the sewage flow climbing up to contact the probe body 121, so as to conduct the two probe bodies 121.

[0033] In some embodiments, the accommodating chamber 111 further has a first end 103 and a second end 104 disposed opposite each other. When the sewage tank 100 is in an upright position, the first end 103 is located above the second end 104. A sewage inlet 112 is located at the first end 103, with a water baffle 130 located between the first end 103 and the second end 104. Under the negative pressure of the cleaning device's fan module, sewage and debris are drawn into the sewage tank 100 along with the airflow. After gas-liquid separation, the sewage and debris ultimately fall into the deeper portion of the accommodating chamber 111, specifically, into the area of ​​the accommodating chamber 111 near the second end 104. Of course, in other embodiments, the sewage inlet 112 may also be located on the first side 101.

[0034] Furthermore, the water retaining plate 130 also includes a water retaining bar 132. The water retaining bar 132 connects the two water retaining portions 131, and the water retaining bar 132 extends from the second side 102 toward the first side 101. Since the water retaining bar 132 extends from the second side 102 of the accommodating chamber 111 toward the detection assembly 120, when the sewage tank 100 is in a flat state and the sewage tank 100 moves back and forth with a large amplitude, the water retaining bar 132 can block the sewage flowing from the second end 104 toward the first end 103 in the accommodating chamber 111, thereby preventing the sewage from flowing toward the sewage inlet 112. In addition, the water retaining bar 132 can also allow sewage to flow toward the first side 101. The water retaining bar 132 connects the two water retaining portions 131, so that the sewage flow flowing along the water retaining portions 131 on both sides toward the probe body 121 is not easily disconnected, which is conducive to the sewage flowing toward the probe body 121 and conducting the two probe bodies 121.

[0035] Specifically, when the water retaining bar 132 extends from the second side 102 toward the first side 101, it is also tilted toward the second end 104. At this time, after the sewage surges toward the water retaining plate 130 and contacts the water retaining bar 132, the water retaining bar 132 can change the direction of the sewage and surge toward the second end 104 deep in the accommodating chamber 111, preventing the sewage from overflowing from the sewage inlet 112.

[0036] Because a set of detection assemblies 120 is used to detect when the sewage tank 100 is full of water in different cleaning positions, to enhance the detection function of the detection assembly 120 in different states of the sewage tank 100, the distances between the two probe bodies 121 and the second end 104 are the same, and the distances between the two probe bodies 121 and the second side 102 are the same. Because the distances between the two probe bodies 121 and the second end 104 are the same, when the sewage tank 100 is in an upright position, the two probe bodies 121 are at the same distance from the bottom of the accommodating cavity 111, allowing both probe bodies 121 to maintain stable contact with the sewage and be guided by the sewage to achieve full water detection. Because the distances between the two probe bodies 121 and the second side 102 are the same, when the sewage tank 100 is in a flat position, the two probe bodies 121 are at the same distance from the bottom of the accommodating cavity 111, allowing both probe bodies 121 to maintain stable contact with the sewage and be guided by the sewage to achieve full water detection.

[0037] In some embodiments, the water baffle 130 is located between one-third and two-thirds of the length of the accommodating chamber 111 in the direction from the first end 103 to the second end 104. The distance between the water baffle 130 and the second end 104 of the accommodating chamber 111 is appropriate, allowing the accommodating chamber 111 to store a certain amount of sewage while maintaining a certain buffer distance from the sewage inlet 112 located at the first end 103. Specifically, the water baffle 130 is located between one-third, one-half, or two-thirds of the length of the accommodating chamber 111 in the direction from the first end 103 to the second end 104. This is not a limitation and can be adjusted based on actual product requirements.

[0038] Furthermore, the detection assembly 120 is located between one-third and two-thirds of the accommodating chamber 111 in the direction from the first side 101 to the second side 102. This distance between the detection assembly 120 and the second side 102 of the accommodating chamber 111 is appropriate. When the sewage tank 100 is in a flat or tilted position, it can store a certain amount of sewage. When the sewage tank 100 reaches a certain amount, the detection assembly 120 can promptly sense the sewage, thereby providing a full water indication. Specifically, in the direction from the first side 101 to the second side 102, the detection assembly 120 is located between one-third, one-half, or two-thirds of the accommodating chamber 111. This is not a limitation and can be adjusted based on actual product requirements.

[0039] In some embodiments, the sewage tank 100 further includes a mounting plate 140. The mounting plate 140 is disposed within the accommodating chamber 111, between the sewage inlet 112 and the second end 104, and the outer periphery of the mounting plate 140 matches the inner wall of the accommodating chamber 111. The mounting plate 140 is provided with a connecting port 141 for allowing sewage and debris entering the accommodating chamber 111 through the sewage inlet 112 to flow deeper into the accommodating chamber 111, that is, toward the second end 104. The detection assembly 120 extends through the mounting plate 140 toward the second end 104, and the detection assembly 120 is located between the connecting port 141 and the first side 101. The water retaining plate 130 is located on the side of the mounting plate 140 facing the second end 104, and the water retaining plate 130 extends from the edge of the connecting port 141 facing the second side 102 toward the detection assembly 120.

[0040] By installing the mounting plate 140 within the accommodating chamber 111, the space between the mounting plate 140 and the second end 104 of the accommodating chamber 111 can better store and isolate sewage. Furthermore, the space between the mounting plate 140 and the first end 103 of the accommodating chamber 111 provides sufficient separation space for the gas-liquid mixture. Because the detection assembly 120 is located between the communication port 141 and the first side 101, it is positioned away from the communication port 141. When sewage passes through the communication port 141, it does not directly contact the detection assembly 120, causing false alarms. Since the water baffle 130 extends from the connecting port 141 toward the edge of the second side 102 toward the direction of the detection assembly 120, the water baffle 130 can play a certain role in shielding the connecting port 141, preventing the sewage from flowing directly out of the connecting port 141 when surging from the second end 104 to the first end 103; however, there is a gap between the water baffle 130 and the connecting port 141, which will not affect the normal flow of sewage and debris through the connecting port 141 toward the second end 104 of the accommodating chamber 111.

[0041] It should be noted that the outer peripheral wall of the mounting plate 140 and the wall of the accommodating chamber 111 are aligned, meaning that a gap between the mounting plate 140 and the wall of the accommodating chamber 111 may be left for installation, but the overall alignment prevents the passage of sewage. The mounting plate 140 is contoured to the radial cross-section of the accommodating chamber 111 to align with the wall of the accommodating chamber 111. Accordingly, the connecting opening 141 is located near the second side 102, and its shape mirrors the shape of the wall of the second side 102 of the accommodating chamber 111. This allows sewage and debris to flow smoothly along the wall of the second side 102 into the accommodating chamber 111, preventing them from becoming stuck as they move through the connecting opening 141 toward the second end 104. A water barrier 132 is provided at the edge of the connecting opening 141 near the second side 102 to fully shield the connecting opening 141 and prevent sewage from flowing directly through the connecting opening 141 to the sewage inlet 112 when the sewage tank 100 is lying flat.

[0042] Furthermore, the water baffle 130 and the mounting plate 140 are integrally formed. Integrating the water baffle 130 and the mounting plate 140 can reduce the number of parts, facilitate production, and facilitate installation and removal of the water baffle 130.

[0043] Furthermore, the mounting plate 140 is snap-fitted to the detection assembly 120. This snap-fitting connection facilitates installation and removal of the mounting plate 140 within the accommodating cavity 111. The snap-fitting connection secures the mounting plate 140 to the detection assembly 120, making assembly and disassembly simple and convenient. Specifically, the mounting plate 140 snaps into contact with the probe carrier 1211 of the detection assembly 120.

[0044] In some embodiments, the housing 110 is further formed with a sewage inlet channel 113, which is separated from the accommodating chamber 111 and communicates with the sewage inlet port 112. An air inlet 114 communicating with the sewage inlet channel 113 is formed at one end of the housing 110 away from the sewage inlet port 112, allowing airflow carrying sewage and debris to enter the sewage inlet channel 113. After gas-liquid separation, the sewage and debris enter the accommodating chamber 111. Of course, in other embodiments, the sewage inlet channel 113 may not be formed in the housing 110, and the sewage inlet port 112 may communicate with an external sewage inlet channel 113.

[0045] In some embodiments, please refer to Figure 4 The sewage tank 100 also includes a cover 150, a baffle 151 and a probe bracket 152. The box body 110 is open at one end corresponding to the sewage inlet 112 of the accommodating chamber 111, and the cover body 150 is covered on the open end of the box body 110. The cover body 150 is used to dock with the fan module to form a negative pressure through which the air supply passes. The baffle 151 is arranged on the inner side of the cover body 150. The baffle 151 is located at the sewage inlet 112. The baffle 151 can guide the sewage after gas-liquid separation to flow into the accommodating chamber 111. The probe bracket 152 is arranged on the inner side of the cover body 150, and the detection assembly 120 is installed on the probe bracket 152. When the cover body 150 is covered on the box body 110, the detection assembly 120 extends into the accommodating chamber 111. By installing the detection assembly 120 on the cover 150 through the probe bracket 152 and snapping the baffle 151 onto the detection assembly 120 , the cover 150 and the box 110 can be disassembled to remove the objects inside the box 110 , making it easier to clean the box 110 .

[0046] Another embodiment of the present application provides a cleaning device (not shown in the figure). The cleaning device includes a cleaning module, a fuselage and a sewage tank 100. The fuselage can be rotatably arranged on the cleaning module, and the sewage tank 100 can be detachably arranged on the fuselage. The sewage tank 100 adopts the sewage tank 100 in any of the above embodiments. The cleaning module is located at the lower end of the fuselage, and the cleaning module is generally used to move on the surface to be cleaned to perform cleaning work. The fuselage can be rotated relative to the cleaning module to adapt to different cleaning scenarios. For example, to clean some sanitary dead corners such as the bottom of the bed and the bottom of the sofa, the fuselage needs to be laid flat. Therefore, by rotating the fuselage relative to the cleaning module, the cleaning device has at least an upright cleaning state, a lying flat cleaning state, and a reclining cleaning state between the upright cleaning state and the lying flat cleaning state, which is beneficial for the cleaning device to clean different areas. As the fuselage rotates, the sewage tank 100 has an upright state, a lying flat state and a reclining state.

[0047] The cleaning device may be a cleaning device such as a floor scrubber or the like that includes a sewage tank 100. Specifically, the cleaning module may be a floor brush module.

[0048] The sewage tank 100 of the cleaning equipment of the present application is provided with a water baffle 130, which at least partially extends between the detection assembly 120 and the second side 102 of the accommodating chamber 111. This allows the sewage tank 100 to share a set of detection assemblies 120 to detect when the sewage tank 100 is full of water in different cleaning positions, thereby reducing costs, reducing the space occupied by the sewage tank 100, and preventing interference between different sets of detection assemblies 120, thereby reducing the false alarm rate. Furthermore, by providing the water baffle 130, the water-full detection sensitivity of the detection assembly 120 of the present application is effectively improved. Compared to existing solutions that require the sewage tank 100 to increase its overall volume to accommodate fault tolerance for water-full detection, the sewage tank 100 of the present application can reduce its volume when the required sewage storage volume is constant, thereby improving the volume utilization rate of the sewage tank 100. The cleaning equipment using the sewage tank 100 of the present application is more lightweight and flexible overall.

[0049] It should be noted that terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they may be slightly tilted. Terms such as "parallel" and "perpendicular" do not imply that components are absolutely parallel or perpendicular to each other, but rather that they may form a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal than "vertical" and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted. Furthermore, terms such as "center," "longitudinal," "transverse," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," and "counterclockwise" indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships typically used when the products of this application are used. These terms are intended solely to facilitate the description of the embodiments of this application and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] It should be understood that "plurality" herein means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. The term "and / or" merely describes an association between associated objects, indicating that three possible relationships exist.
