[0042] Please refer to Figures 1, 12, 13, 14, and 18. This application provides an embodiment of a cleaning device. The cleaning device may include a separation device 100, a brush head device 200, a liquid storage tank 300, a main unit 400, and a wastewater storage tank 500. The liquid storage tank 300 can be used to store cleaning fluid and includes a liquid outlet component 314, which allows the liquid outlet 312 of the liquid storage tank 300 to contact the liquid when the cleaning device is in any position. The wastewater storage tank 500 can be connected to the separation device 100 and can be used to store wastewater. The wastewater storage tank 500 includes a liquid guiding component 535, which guides wastewater into the wastewater storage tank 500. The liquid guiding port of the liquid guiding component 535 does not contact the wastewater in the wastewater storage tank 500 when the cleaning device is in any position. Specifically, the brush head device 200 can be used to clean the surface to be cleaned. The brush head device 200 may include a water suction port 210, which can be used to suck up the wastewater from the surface to be cleaned. The separation device 100 can be connected to the main unit 400 and is used to perform gas-liquid separation of wastewater.

[0043] In some embodiments, the sludge storage tank 500 can be connected to the separation device 100 via a pipe, or it can be directly connected to the separation device 100 to allow wastewater in the separation device 100 to be introduced into the sludge storage tank 500. The wastewater may include liquid pollutants such as cleaning waste liquid and oil, as well as solid pollutants such as hair clippings, paper scraps, and dust.

[0044] In some embodiments, the main unit 400 may include a grip housing 420 and a negative pressure device 410. The grip housing 420 may form a grip portion 420b and an air outlet portion 420a. The air outlet portion 420a may be used to house the negative pressure device 410. When the negative pressure device 410 is working, it can generate a suction airflow. This suction airflow forms a negative pressure in the cleaning device, thereby achieving the function of suction cleaning. The negative pressure device 410 may be a fan.

[0045] In some embodiments, the host 400 may further include a power supply device 430 and an electronic control device 440, wherein the power supply device 430 may include a power source, and the electronic control device 440 may include a display screen, buttons, triggers, switches or touch screens, and the negative pressure device 410, the electronic control device 440 and the power supply device 430 may be electrically connected to the brush head device 200 and the separation device 100.

[0046] In some embodiments, the cleaning device may include a main unit 400, a liquid storage tank 300, a brush head device 200, a separation device 100, and a sludge storage tank 500. The liquid storage tank 300 can be used to store cleaning liquid. The liquid storage tank 300 may include a liquid outlet component 314, which can be used to allow the liquid outlet 312 of the liquid storage tank 300 to contact the liquid when the cleaning device is in any position. The brush head device 200 can be used to clean the surface to be cleaned. The brush head device 200 may include a water suction port 210, which can be used to suck up the wastewater from the surface to be cleaned.

[0047] Furthermore, the separation device 100 can be connected to the main unit 400 for gas-liquid separation of wastewater, and the wastewater storage tank 500 can be connected to the separation device 100 for storing wastewater. The wastewater storage tank 500 may include a liquid guiding component 535, which can be used to guide wastewater into the wastewater storage tank 500. The liquid guiding port of the liquid guiding component 535 does not come into contact with the wastewater in the wastewater storage tank 500 when the cleaning equipment is in any position. The connection between the separation device 100 and the main unit 400 may include one or more of the following: electrical connection, communication connection, structural fixed connection, or detachable connection.

[0048] In some embodiments, the brush head device 200 may be connected to at least one of the liquid storage tank 300, the separation device 100, and the sludge storage tank 500, and is also connected to the main unit 400, for performing brushing, scraping, and wastewater recovery operations on the target to be cleaned. The liquid storage tank 300 is connected to the brush head device 200 and the main unit 400, for supplying cleaning water to the brush head device 200. The separation device 100 is connected to the sludge storage tank 500 and the main unit 400, for separating the recovered wastewater into the sludge storage tank 500, which stores the separated wastewater.

[0049] For example, the liquid storage tank 300, the separation device 100, and the sludge storage tank 500 can be stacked and connected to the main unit 400 respectively, and the brush head device 200 is connected to the separation device 100. When the main unit 400 is started, the liquid storage tank 300 sprays cleaning water onto the target to be cleaned through the brush head device 200. The brush head device 200 performs a brushing and scraping action while collecting the generated wastewater. The wastewater is separated by the separation device 100, and the resulting waste liquid enters the sludge storage tank 500 for storage.

[0050] It is understood that the liquid storage tank 300 and the sludge storage tank 500 may also be installed on the same floor as the separation device 100; and / or, the liquid storage tank 300 may be connected to the main unit 400 and / or the separation device 100, without limitation here.

[0051] In embodiments of this application, a water pump device may be disposed within the grip portion 420b for pumping clean water from the liquid storage tank 300 (e.g., a clean water tank) to the brush head device 200 and spraying it onto the cleaning brush; a peristaltic pump may be disposed within the air outlet portion 420a for pumping cleaning agent from the liquid storage tank 300 (e.g., a cleaning agent tank) to the brush head device 200 and spraying it onto the cleaning brush.

[0052] Understandably, since the liquid outlet component 314 can be used to ensure that the liquid outlet 312 of the liquid storage tank 300 can contact the liquid when the cleaning equipment is in any position, and the liquid guide component 535 can ensure that the liquid guide port does not contact the sewage in the sewage storage tank 500 when the cleaning equipment is in any position, the problem of sewage backflow caused by the liquid guide component 535 being submerged in sewage is reduced, and the problem of the liquid outlet 312 not being able to contact the liquid and not being able to discharge water is also reduced, thereby improving the cleaning efficiency of the cleaning equipment when used in multiple positions, and enabling the omnidirectional cleaning function of the cleaning equipment to be realized.

[0053] Please refer to Figures 2, 10 to 14. This application embodiment proposes a liquid storage tank 300, which may include a liquid storage shell 310. The liquid storage shell 310 may form a liquid storage cavity 317 with a liquid inlet 311 and a liquid outlet 312.

[0054] In some embodiments, as shown in Figures 1, 12, and 13, the liquid storage tank 300 may include a liquid storage shell 310, which may be provided with a vent 315. The liquid storage shell 310 may be detachably connected to the separation device 100, and the liquid storage shell 310 forms a liquid storage cavity 317 having a liquid inlet 311 and a liquid outlet 312. Specifically, the liquid outlet component 314 may include an air bladder, which may be disposed in the liquid storage cavity 317 and connected to external air through the vent 315. When the liquid volume in the liquid outlet cavity decreases, the air bladder will expand due to the pressure difference between the inside and outside, thereby forcing the liquid in the liquid storage cavity 317 toward the liquid outlet 312, thus realizing the omnidirectional liquid outlet function of the liquid storage tank 300.

[0055] In other embodiments, the liquid outlet component 314 may include a load and a liquid outlet pipe. The first end of the liquid outlet pipe is connected to the liquid outlet 312, and the second end of the liquid outlet pipe is connected to the load and disposed within the liquid outlet chamber. The load may include a gravity block or a gravity ball, and the liquid outlet pipe may be a flexible hose. The load can use gravity to submerge the opening of the liquid outlet pipe into the liquid in the liquid storage chamber 317. Therefore, when the cleaning equipment is in any posture, the liquid outlet 312 of the liquid storage tank 300 can contact the liquid in the liquid storage chamber 317, thereby achieving omnidirectional liquid outlet function of the liquid outlet tank.

[0056] In some embodiments, the liquid storage housing 310 may be recessed to form an adaptation groove 313, and when the liquid storage chamber 300 is adapted to the separation device 100, the separation device 100 is at least partially housed in the adaptation groove 313. Further, the liquid storage chamber 300 may also include a locking component 320, which may be disposed on the liquid storage housing 310 and used to form a structural lock with the separation device 100, so that the liquid storage housing 310 and the separation device 100 are adapted to each other. The liquid storage cavity 317 may be used to store cleaning fluid, which includes, but is not limited to, water, detergent, or a mixture of water and detergent. The user can add cleaning fluid into the liquid storage cavity 317 through the inlet 311, and the cleaning fluid in the liquid storage cavity 317 can be delivered to the brush head device 200 through the outlet 312. For example, the main unit 400 is provided with a power element, and under the action of the power element, the cleaning fluid in the liquid storage cavity 317 can be delivered to the brush head device 200 through the outlet 312. The power element includes, but is not limited to, a water pump.

[0057] It is understandable that after the liquid storage tank 300 and the separation device 100 are adapted and installed, at least a part of the separation device 100 can be accommodated in the adaptation groove 313, thereby using the adaptation groove 313 to limit the separation device 100 in a local direction, improve the connection tightness, and make the overall cleaning equipment compact.

[0058] Furthermore, the locking component 320 and the housing 120 of the separation device 100 can form a structural lock, so that the liquid storage tank 300 and the separation device 100 can be firmly connected after the structural lock is formed, and the contact lock facilitates the disassembly and maintenance of the liquid storage tank 300 and the separation device 100.

[0059] Furthermore, since the storage tank 300 can be used to store cleaning fluid, after the storage tank 300 and the separation device 100 are adapted, the cleaning fluid stored in the storage tank 300 absorbs the local heat generated by the separation device 100 during operation, thereby reducing the temperature rise of the separation device 100 and effectively improving the service life of the separation device 100. In one embodiment, the storage housing 310 includes a storage tank body 3101 and a cover 3102. The storage tank body 3101 forms a storage cavity 317 with an inlet 311 and an outlet 312. The cover 3102 covers the inlet 311 and is detachably connected to the storage tank body 3101. An adapter groove 313 is formed on the side of the storage tank body 3101 away from the cover 3102.

[0060] In one embodiment, a limiting structure is provided on the side of the liquid storage tank 3101 away from the cover 3102. Furthermore, when the liquid storage tank 300 is adapted to the separation device 100, the limiting structure and the separation device 100 form a limiting fit in at least two mutually perpendicular directions. The limiting structure can be a limiting groove 3106 or a limiting protrusion 306. When the limiting structure is a limiting groove 3106, the separation device 100 is provided with a limiting protrusion 306 adapted to the limiting groove 3106. When the limiting structure is a limiting protrusion 306, the separation device 100 is provided with a limiting groove 3106 adapted to the limiting groove 3106, thereby allowing the liquid storage tank 310 and the separation device 100 to form a limiting fit in two mutually perpendicular directions.

[0061] Please refer to Figures 2 and 11. For example, the separation device 100 is provided with a limiting protrusion 306 on the side near the liquid storage shell 310, and the liquid storage tank 3101 is provided with a limiting groove 3106 that matches the limiting protrusion 306 on the side near the separation device 100. When the separation device 100 and the liquid storage tank 300 are connected in a matching manner, the limiting protrusion 306 of the separation device 100 and the limiting groove 3106 of the liquid storage tank 300 form a limiting fit in the horizontal direction.

[0062] Referring to Figures 8 and 9, in some embodiments, the adapter slot 313 includes a first adapter portion 3131 and a second adapter portion 3132 communicating with the first adapter portion 3131. Specifically, a portion of the structure of the separation device 100 (e.g., at least one of the housing 120, impeller assembly 130, and filter member 123) may be accommodated in the first adapter portion 3131. The ventilation duct communicating between the separation device 100 and the fan component of the main unit 400 may be accommodated in the second adapter portion 3132. By accommodating a portion of the structure of the separation device 100 in the adapter slot 313, a compact structure is achieved.

[0063] In some embodiments, the locking member 320 has a switchable locked state and an unlocked state. When the locking member 320 is in the locked state, it and the separation device 100 form a structural lock, connecting the liquid storage housing 310 and the separation device 100. When the locking member 320 is triggered by an external force, it can switch from the locked state to the unlocked state, thereby releasing the structural lock with the separation device 100. Furthermore, when the structural lock between the locking member 320 and the separation device 100 is released, the separation device 100 can be separated from the liquid storage housing 310.

[0064] For example, after the liquid storage tank 300 and the separation device 100 are adapted, the locking component 320 is in a locked state. At this time, the liquid storage tank 300 and the separation device 100 form a structural lock, thereby achieving a tight connection. In the event that the liquid storage tank 300 and the separation device 100 need to be disassembled and separated, an external force is applied to the locking component 320, which can switch the locking state to an unlocked state to release the structural lock with the separation device 100. Thus, under the action of external force, the liquid storage tank 300 and the separation device 100 can be separated relatively easily.

[0065] In some embodiments, referring to Figures 13 and 14, the locking component 320 includes a first locking assembly 3201, a second locking assembly 3202, and a third locking assembly 3203. The third locking assembly 3203 includes a third locking member 3231 and a third elastic member 3232. The third locking member 3231 is provided with a limiting protrusion 306 and is movably disposed on the separation device 100. One end of the third elastic member can abut against the separation device 100, and the other end can push the third locking member 3231 and force the second locking assembly 3203 to move when compressed. The first locking assembly 3201 and the second locking assembly 3202 are movably disposed on the liquid storage housing 310.

[0066] For example, when an upward force is applied to the first locking assembly 3201, the second locking assembly 3202 moves to the right under the push of the first locking member 3211; when a downward force is applied to the first locking assembly 3201 or the first locking assembly 3201 is released, the second locking assembly 3202 moves to the left under the drive of the third elastic member 3232 and the third locking member 3231. The first locking assembly 3201 is slidably disposed on the liquid storage housing 310 and can be displaced relative to the liquid storage housing 310 in the vertical direction. The second locking assembly 3202 is slidably disposed on the liquid storage housing 310 and can be displaced relative to the liquid storage housing 310 in the horizontal direction.

[0067] Optionally, the first locking component 3201 is provided with a force-applying surface that contacts the second locking component 3202 to apply force to the second locking component 3202, wherein the force-applying surface is wedge-shaped or arc-shaped. For example, when an external force is applied to the handle of the first locking component 3211, the first locking component 3211 can be displaced relative to the housing, so that the first elastic component 3212 elastically stores force, and the second locking component 3202 can be structurally unlocked from the separation device 100; when the external force is removed, the first elastic component 3212 elastically resets to drive the first locking component 3211 to apply force to the second locking component 3202, and the second locking component 3202 forms a structural lock with the separation device 100.

[0068] Under the force applied by the first locking assembly 3201, the second locking member 3221 and the third locking member 3231 can be displaced relative to the liquid storage shell 310, so that the second elastic member 3222 and the third elastic member 3232 can elastically store force, and the second locking assembly 3202 and the third locking assembly 3203 can be structurally locked with the separation device 100; when the force applied by the first locking assembly 3201 is removed, the third elastic member 3232 and the second elastic member 3222 elastically reset, so that the second locking member 3221 can be displaced relative to the liquid storage shell 310, and the second locking assembly 3202 forms a structural lock with the separation device 100.

[0069] In some embodiments, the liquid storage housing 310 may further include an anti-clogging component 316, which is positioned and covers the outlet 312. Specifically, the anti-clogging component 316 may be a grid 1117. For example, the grid 1117 is 1-2 cm higher than the housing. By providing the anti-clogging component 316, the airbag can be prevented from blocking the outlet 312 during expansion, thereby ensuring continuous water output from the outlet 312.

[0070] Please refer to Figures 1 to 6. As shown in Figures 1 to 6, the separation device 100 may include a separation chamber 110 and an impeller assembly 130. The separation device 100 can be applied to cleaning equipment. A first accommodating space 111 may be formed inside the separation chamber 110. The impeller assembly 130 may be at least partially disposed in the first accommodating space 111. For example, the impeller assembly 130 may include an impeller motor 131 and an impeller 132, with the impeller motor 131 connected to the impeller 132. The separation chamber 110 or the first accommodating space 111 can be used to accommodate the impeller 132 of the impeller assembly 130. By partially disposing the impeller assembly 130 in the first accommodating space 111, the separation device 100 can achieve gas-liquid separation through the impeller assembly 130.

[0071] Specifically, the first accommodating space 111 can serve as the working space when the separation device 100 performs gas-liquid separation. The impeller motor 131 drives the impeller 132 to rotate. When the impeller 132 rotates, it generates centrifugal force on the sewage entering the first accommodating space 111, causing the sewage to flow along the inner wall of the separation chamber 110.

[0072] In some embodiments, the separation device 100 may further include a capture column 113 formed on the side wall of the separation chamber 110. The capture column 113 includes a capture channel 1131 that communicates with the first accommodating space 111. When the separation device 100 activates the gas-liquid separation function, wastewater is propelled by centrifugal force to flow along the inner wall of the separation chamber 110 and enter the capture channel 1131 of the capture column 113, and then enters the wastewater storage chamber 500 of the cleaning equipment through the capture channel 1131.

[0073] In some embodiments, the capture column 113 can be optimized to improve the wastewater capture efficiency, capture wastewater more quickly and introduce it into the sludge storage tank 500, prevent wastewater from accumulating inside the separation chamber 110 and reducing gas-liquid separation efficiency, improve the gas-liquid separation performance of the separation device 100 and the cleaning equipment, and enhance the cleaning efficiency of the separation device 100 and the cleaning equipment. The cross-section of the capture channel 1131 can gradually increase from the top to the bottom of the separation chamber 110.

[0074] For example, the capture column 113 may form a first cylindrical surface 1133 and a second cylindrical surface 1134 corresponding to the capture channel 1131, wherein the first cylindrical surface 1133 is disposed at the top end of the capture column 113, and the second cylindrical surface 1134 is disposed at the bottom end of the capture column 113, and the area of ​​the first cylindrical surface 1133 is smaller than that of the second cylindrical surface 1134; and / or, the capture column 113 may be provided with a guide surface 1132, which may be inclined to the rotation axis of the impeller 132.

[0075] Understandably, by optimizing the guidance of the capture column 113, especially the design of the guide surface 1132 and the channel cross-section, the principle of centrifugal force can be fully utilized, allowing sewage to flow smoothly along the capture channel 1131 after entering the capture column 113. This enables the separation device 100 to capture sewage smoothly in various positions and guide it into the sewage storage tank 500. Consequently, the separation device 100 and the cleaning equipment it is used in have the possibility of omnidirectional use, making it convenient for users to clean ceilings, walls, the lower edge of cabinets, and other locations, thereby improving the safety and cleaning efficiency of the separation device 100 and the cleaning equipment.

[0076] In some embodiments, the capture column 113 may have a capture port 1135, and the capture channel 1131 communicates with the first accommodating space 111 through the capture port 1135. Specifically, the height of the capture port 1135 may be less than or equal to the height of the capture column 113, and / or the width of the capture port 1135 may be less than or equal to three-quarters of the diameter of the capture channel 1131.

[0077] It is understandable that appropriately enlarging the capture port 1135 that connects the capture column 113 and the first accommodating space 111 can increase the contamination area of ​​the capture column 113, thereby improving the contamination efficiency.

[0078] In some embodiments, please refer to Figure 3. As shown in Figure 3, the opening of the capture port 1135 of the capture column 113 may be offset from the axis of rotation of the impeller 132 and directed against the direction of sewage flow. And / or, the separation chamber 110 may include an inlet channel 114, wherein the axis of the inlet channel 114 may be offset from the axis of rotation of the impeller 132 and directed in the direction of sewage flow.

[0079] By adjusting the axial direction of the liquid inlet channel 114, the sewage in the separation chamber can be more smoothly driven by the impeller 132 to achieve gas-liquid separation. By adjusting the opening orientation of the capture port 1135, the sewage in the separation chamber can be more smoothly captured by the capture column 113.

[0080] In some embodiments, the separation chamber 110 may include a separation chamber body 1114 and a separation chamber channel component 1115. The separation chamber channel component 1115 may be connected to or integrally formed with the separation chamber body 1114, and the separation chamber channel component 1115 may form a liquid inlet channel 114. The liquid inlet channel 114 may include a first channel opening 1141 and a second channel opening 1142. The liquid inlet channel 114 communicates with the first accommodating space 111 through the first channel opening 1141, and the second channel opening 1142 is used to communicate with the channel of the brush head device 200 of the cleaning equipment. The separation chamber channel component 1115 may be detachably connected to the separation chamber body 1114, or it may be fixedly connected to the separation chamber body 1114 by means of screws, adhesives, or integral forming.

[0081] By dividing the separation chamber 110 into the separation chamber body 1114 and the separation chamber channel component 1115, the structural complexity and overall volume of the separation chamber 110 can be reduced, thereby reducing the difficulty of manufacturing, assembling and transporting the separation chamber 110. This not only facilitates large-scale production and transportation, but also allows users or manufacturers to replace and assemble different liquid inlet channel components 114 as needed, improving the convenience of expansion, maintenance and installation of the separation device 100 and cleaning equipment.

[0082] In some embodiments, the gas-liquid separation performance of the separation device 100 can be further improved by adjusting the structural design of the separation chamber channel component 1115, thereby improving the cleaning efficiency of the separation device 100 and the cleaning equipment. Specifically, the area of ​​the second channel opening 1142 can be smaller than that of the first channel opening 1141, and / or the center point of the first channel opening 1141 is closer to the bottom of the first accommodating space 111 than the center point of the second channel opening 1142. By increasing the contact area between the liquid and the separation chamber 110 when the liquid leaves the inlet channel 114, the liquid can more easily form small droplets in the first accommodating space 111 or be quickly driven by the impeller 132, thereby improving the gas-liquid separation efficiency of the separation device 100.

[0083] By adjusting the center point positions of the first channel opening 1141 and the second channel opening 1142, firstly, the structure can be made more compact, reserving installation space for components such as the mounting base 150 of the brush head device 200 and the installation space for water and electricity wiring; secondly, when the bottom of the separation chamber 110 is matched with the sludge storage chamber 500, the droplets entering the first accommodating space 111 through the liquid inlet channel 114 are closer to the inlet of the sludge storage chamber 500, thereby reducing the difficulty of sewage capture and improving sewage capture efficiency; thirdly, when an impeller 132 is provided in the middle of the first accommodating space 111, the possibility of sewage being driven by the impeller 132 can be increased, thereby improving the gas-liquid separation efficiency of the separation device 100.

[0084] In some embodiments, the separation device 100 further includes a housing 120, which may be used to house at least a portion of the filter element 123 and / or at least a portion of the impeller assembly 130, and may also be fitted onto the separation chamber 110 and form a second accommodating space 112 with the separation chamber 110. For example, the housing 120 may be used to house the impeller motor 131 of the impeller assembly 130 and the filter element 123.

[0085] Understandably, by separating the separation device 100 into the separation chamber 110 and the housing 120, it is easier to install the impeller assembly 130 into the separation chamber 110, thereby facilitating the assembly and automated production of the separation device 100. On the other hand, it is also easier for users and manufacturers to disassemble, install, and maintain the separation device 100, thereby reducing the after-sales maintenance costs of the separation device 100 and the cleaning equipment.

[0086] In some embodiments, please refer to Figures 6 to 8. As shown in Figures 6, 7, and 8, the bottom of the separation chamber 110 can extend outward to form a first outer edge 124. The inner wall of the bottom of the accommodating housing 120 can be provided with a first fixing member 1243. The separation chamber 110 can be fixedly connected to the accommodating housing 120 through the cooperation of the first outer edge 124 and the first fixing member 1243.

[0087] It is understandable that by fixing the separation chamber 110 to the housing 120 through the first outer edge 124 and the first fixing member 1243, the installation of the housing 120 can be facilitated, and the structure of the separation device 100 and the cleaning equipment can be made more compact, which is conducive to the miniaturization and convenience of the equipment design. The first fixing member 1243 may also be provided with reinforcing ribs to enhance the mechanical structural strength of the product and improve the durability of the separation device 100 and the cleaning equipment.

[0088] In some embodiments, please refer to Figures 1 and 4. As shown in Figures 1 and 4, the main unit 400 may include a negative pressure device 410, and the housing 120 includes an air outlet channel 115, which is disposed opposite to the liquid inlet channel 114 and communicates with the negative pressure device 410. The separation chamber 110 may have an air outlet 1111, and the housing 120 may form an air outlet channel 115 corresponding to the air outlet 1111, which communicates with the negative pressure device 410.

[0089] By arranging the air outlet channel 115 and the liquid inlet channel 114 opposite to each other, the separation device 100 can be positioned at the center of the overall cleaning equipment. For example, the separation device 100 can be positioned between the main unit 400, the negative pressure device 410, the brush head device 200, and the mounting base 150. This allows users to adjust the center of gravity and change their posture during use, thereby improving the user's grip and posture adjustment controllability, and improving the performance of the cleaning equipment.

[0090] In some embodiments, the air outlet 115 may include a third channel port 1151 and a fourth channel port 1152. Specifically, the third channel port 1151 corresponds to the air outlet 1111, and the fourth channel port 1152 corresponds to the negative pressure device 410. The filter member 123 may be disposed between the third channel port 1151 and the fourth channel port 1152, or directly disposed at the third channel port 1151 or the fourth channel port 1152.

[0091] For example, please refer to Figures 5 and 6. As shown in Figures 5 and 6, the filter element 123 can be a filter cylinder and is fitted around the periphery of the third channel opening 1151. Since the filter element 123 is a filter cylinder, it can form a receiving space, thereby accommodating at least a portion of the impeller assembly 130. The filter cylinder design reduces the sealing difficulty of right angles in the structure or space of traditional cleaning equipment, thereby reducing the process costs of installation and sealing, and facilitating user replacement of the filter cylinder. By forming a receiving space, the overall structure of the cleaning equipment can be made more compact and aesthetically pleasing, facilitating storage and transportation.

[0092] In some embodiments, the periphery of the fourth channel opening 1152 may be provided with a slope 1153, which can be used to place the seal 160. By providing a slope 1153 on the periphery of the fourth channel opening 1152, the difficulty of stably placing the seal 160 during installation can be reduced, facilitating automated and large-scale production.

[0093] For example, when the separation device 100 and the cleaning equipment are disassembled and cleaned on the production line or by users, they are often placed vertically. Without the slope 1153, when the separation device 100 is used in conjunction with the main unit 400 of the cleaning equipment and its air duct components, the sealing element 160 may slip off. However, if a slope 1153 is provided on the periphery of the part with the fourth channel opening 1152, and another corresponding slope 1153 is provided on the main unit 400 of the cleaning equipment or its air duct components, the sealing element 160 can be placed on the slope 1153, making the connection more convenient.

[0094] In some embodiments, please refer to Figures 4 to 7. As shown in Figures 4 to 7, a motor mounting base 1116 may be provided on the separation chamber 110 corresponding to the air outlet 1111. The motor mounting base 1116 may be disposed at the air outlet 1111 and may be used to fix at least a portion of the impeller assembly 130. The motor mounting base 1116 may be connected to the separation chamber 110 via a grille 1117 corresponding to the air outlet 1111, and the motor mounting base 1116 may be used to fix the impeller motor 131.

[0095] In some embodiments, the separation chamber 110 is provided with a motor protection cover 145 corresponding to the motor mounting base 1116. The motor protection cover 145 is fitted to the motor mounting base 1116 and covers the impeller motor 131. The motor protection cover 145 and / or the motor mounting base 1116 can form at least one wiring port 144.

[0096] By forming the wiring port 144, it is possible to facilitate the wiring of the impeller assembly 130 and other electronic components between the motor protective cover 145 and the motor mounting base 1116. For example, the motor mounting base 1116 and / or the motor protective cover 145 may also be provided with a speed sensor for detecting the speed of the impeller motor 131.

[0097] To prevent droplets from entering the impeller motor 131 and causing short circuits or other malfunctions, the wiring port 144 can be sealed with adhesive or blocked after wiring is completed, thereby improving waterproofing and airtightness, and enhancing the durability and safety of the separation device 100 and the cleaning equipment.

[0098] In some embodiments, please refer to Figures 5 to 8. As shown in Figures 5, 6, 7 and 8, the housing 120 may include a first housing 121 and a second housing 122. The housing 120 that fits onto the separation chamber 110 and forms a second accommodating space 112 with the separation chamber 110 may be referred to as the first housing 121, and the housing 120 that accommodates at least a portion of the filter member 123 and / or the impeller assembly 130 may be referred to as the second housing 122.

[0099] In some embodiments, the separation chamber 110 may be provided with a first outer edge 124, and the bottom of the second accommodating housing 122 may extend outward to form a second outer edge 125. The inner wall of the top of the first accommodating housing 121 may be provided with a second fixing member 1253, and the second accommodating housing 122 is fixedly connected to the accommodating housing 120 through the cooperation of the second outer edge 125 and the second fixing member 1253.

[0100] Understandably, by fixing the second accommodating housing 122 to the accommodating housing 120 via the second outer edge 125 and the second fixing member 1253, space can be reserved for the installation of some electronic components, making the structure of the separation device 100 and the cleaning equipment more compact, which is conducive to the miniaturization and convenience of the equipment design. On the other hand, it can improve the mechanical structural strength of the separation device 100 and the cleaning equipment. Furthermore, the second fixing member 1253 can be provided with reinforcing ribs to enhance the mechanical structural strength of the product and improve the durability of the separation device 100 and the cleaning equipment.

[0101] It can be further understood that the fixed connection design between the separation chamber 110 and the second accommodating shell 122 and the first accommodating shell 121 can not only strengthen the structural strength of the separation chamber 110 and the cleaning equipment, but also provide a mounting base for water and electricity lines and various electronic components by using fasteners and / or outer edges. Thus, the safety and structural compactness of the separation chamber 110 and the cleaning equipment are enhanced from both mechanical and electronic design perspectives.

[0102] In some embodiments, the first outer edge 124 may abut against the inner wall of the first accommodating housing 121, and the second outer edge 125 may abut against the inner wall of the accommodating housing 120 to enclose the second accommodating space 112. By enclosing the second accommodating space 112, various electronic components and electrical wiring within the second accommodating space 112 can be effectively protected from external environmental contamination. Furthermore, the appearance of the separation device 100 and the cleaning equipment is clearer and neater, preventing minor bumps from causing malfunctions in electronic components and electrical wiring. The second accommodating space 112 can serve as a space for accommodating electrical wiring, making the wiring clearer and safer, and resulting in a more compact structure for the cleaning equipment, thus facilitating its miniaturization.

[0103] In some embodiments, the first outer edge 124 or the second outer edge 125 can be pre-installed with the first receiving housing 121. For example, the edge of the first outer edge 124 may be provided with at least one first latching member 1241, and the inner wall of the receiving housing 120 may be provided with at least one first slot 1242. The first latching member 1241 can cooperate with the first slot 1242, and at least one of the first latching member 1241 and the first slot 1242 is elastic. And / or, the edge of the first outer edge 124 may be provided with at least one first slot 1242, and the inner wall of the receiving housing 120 may be provided with at least one first latching member 1241. The first slot 1242 can cooperate with the first latching member 1241, and at least one of the first latching member 1241 and the first slot 1242 is elastic.

[0104] For example, the edge of the second outer edge 125 may be provided with at least one second slot 1252, and the inner wall of the accommodating housing 120 may be provided with at least one second fastener 1251. The second elastic slot and the second fastener 1251 can cooperate to achieve pre-installation of the first accommodating housing 121 and the second accommodating housing 122. At least one of the second fastener 1251 and the second slot 1252 is elastic. And / or, the edge of the second outer edge 125 may be provided with at least one second fastener 1251, and the inner wall of the accommodating housing 120 may be provided with at least one second slot 1252. The second fastener 1251 and the second slot 1252 can cooperate to achieve pre-installation of the first accommodating housing 121 and the second accommodating housing 122. At least one of the second fastener 1251 and the second slot 1252 is elastic.

[0105] The system utilizes slots, buckles, rotating bayonets, or threaded connections to achieve pre-installation or detachable connections. This ensures structural strength while guaranteeing ease of product manufacturing and installation, and also facilitates disassembly, maintenance, and expansion modifications.

[0106] In some embodiments, the separation device 100 may further include a circuit assembly 140, which may be disposed in the second accommodating space 112, electrically connected to the host 400, and electrically connected to the brush head device 200 and the separation device 100.

[0107] Understandably, by placing the circuit assembly 140 in the second accommodating space 112, wiring can be implemented starting from the separation device 100 located in the middle of the cleaning equipment. This saves on wiring materials, makes the wiring clearer and simpler, shortens the length of individual electrical connection wires, increases the strength of the wire structure, reduces the risk of wire breakage due to external impacts, and makes electricity use safer.

[0108] In some embodiments, the circuit assembly 140 may include at least one circuit board 141, which may be arc-shaped or annular, and at least a portion of the circuit board 141 may surround the separation chamber 110. By making the circuit board 141 arc-shaped or annular, the second accommodating space 112 can be utilized to a greater extent, thereby utilizing a larger area of ​​the circuit board 141 to integrate as many electronic components as possible, making the electronic wiring clearer, improving the modularity of electronic component integration, and simplifying the production, installation, and software debugging of the separation device 100 and the cleaning equipment.

[0109] In some embodiments, a sensor 570 may be provided on the brush head device 200 or the main unit 400, and the circuit assembly 140 is electrically connected to a sensor corresponding to the sensor 570, which can detect the tightness of the connection when the brush head device 200 or the main unit 400 is connected to the separation device 100.

[0110] For example, the sensor can also be a mechanical sensor such as a limit switch, a magnetic induction sensor such as a Hall element, a photoelectric sensor such as a photoelectric switch, or a capacitive or electrode sensor. The sensing element 570 and the sensor can be respectively set at the corresponding connection points between the brush head device 200 and the separation device 100, or respectively set near the corresponding connection points between the host device 400 and the separation device 100.

[0111] For example, the sensor can also be a mechanical sensor such as a limit switch, a photoelectric sensor such as a photoelectric switch, or a capacitive or electrode sensor. By setting the sensing element 570 and the sensor, the tightness of the connection can be easily detected, preventing users from using the cleaning equipment rashly before it is properly installed, which could cause problems such as leakage or damage. In addition, setting the sensing element 570 or the sensor in the second accommodating space 112 can facilitate electrical connection to the circuit assembly 140, and can also optimize the internal space, making the structural design of the separation device 100 and the cleaning equipment more compact and the water and electricity wiring more convenient.

[0112] In some embodiments, please refer to FIG5. As shown in FIG1, FIG4 and FIG5, the impeller 132 may include a first impeller portion 1321, a second impeller portion 1322 and a third impeller portion 1323. The impeller 132 is disposed in the first accommodating space 111, wherein the first impeller portion 1321 corresponds to the inner top of the separation chamber 110, the third impeller portion 1323 corresponds to the inner bottom of the separation chamber 110, and the second impeller portion 1322 is disposed between the first impeller portion 1321 and the third impeller portion 1323.

[0113] The second impeller section 1322 has a minimum number of blades ranging from 8 to 62, and the third impeller section 1323 has a minimum number of blades ranging from 3 to 62. The impeller motor 131 of the impeller assembly 130 has a maximum speed range of 4,000 to 20,000 revolutions per minute, thereby ensuring the gas-liquid separation efficiency of the separation device 100.

[0114] It is understandable that when the first impeller 1321 is waterproofed to the inner top of the separation chamber 110, it can achieve a waterproof effect. In addition, with the gas-liquid separation efficiency of the second impeller 1322 and the third impeller 1323, the first impeller 1321 does not need to be equipped with blades.

[0115] It can be further understood that the first impeller portion 1321, the second impeller portion 1322, and the third impeller portion 1323 can also be understood as positional concepts. For example, the first impeller portion 1321 is a part of the impeller 132 corresponding to the inner top of the separation chamber 110, and the third impeller portion 1323 is a part of the impeller 132 corresponding to the inner bottom of the separation chamber 110. In particular, when the number of blades in the second impeller portion 1322 and the third impeller portion 1323 are equal, they can form the same set of blades. In this case, the second impeller portion 1322 can represent the upper half of the set of blades near the inner top of the separation chamber 110, and the third impeller portion 1323 can represent the lower half of the set of blades near the inner bottom of the separation chamber 110.

[0116] For example, the first impeller portion 1321, the second impeller portion 1322, and the third impeller portion 1323 can also be understood as follows: the first impeller portion 321 can be one-third of the impeller 132 corresponding to the inner top of the separation chamber 110; the third impeller portion 323 can be one-third of the impeller 132 corresponding to the inner bottom of the separation chamber 110; and the second impeller portion 1322 can be at least a portion of the impeller 132 located between the first impeller portion 1321 and the third impeller portion 1323.

[0117] In some embodiments, the impeller assembly 130 may further include an impeller fixing bracket 133 and an impeller drive shaft 134. The impeller fixing bracket 133 is provided with a through hole. One end of the impeller drive shaft 134 is movably inserted through the through hole into the impeller fixing bracket 133 and connected to the impeller 132. The other end of the impeller drive shaft 134 is connected to the impeller motor 131.

[0118] In some embodiments, the impeller assembly 130 may further include an impeller coupling 135, through which the power output shaft of the impeller motor 131 can be connected to the impeller drive shaft 134. Through the design of the impeller coupling 135 and / or the impeller fixing bracket 133 and the impeller drive shaft 134, the mechanical structural strength and operational stability of the impeller assembly 130 and even the separation device 100 can be improved. First, the negative impact of external collisions on the equipment can be reduced through mechanical strength redundancy; second, vibration and noise can be reduced, ensuring long-term stable operation of the equipment; third, speed measurement accuracy and rotational stability can be ensured, and the control function of the impeller assembly 130 can be ensured to be stable and effective, thereby facilitating control reliability and performance stability.

[0119] In some embodiments, to prevent wastewater in the first accommodating space 111 from being accidentally drawn into the impeller motor 131, the negative pressure device 410, or the main unit 400, the gap between the impeller 132 and the separation chamber 110 can be waterproofed or drained. Specifically, the design of the annular groove 1113 and the annular protrusion 1112 can form a movable fit, and / or the form of the fitting surface 523 or the like can achieve the function of preventing accidental suction and drainage.

[0120] For example, the annular groove 1113 can be provided on the inner top of the separation chamber 110, and the annular protrusion 1112 can be provided on the first impeller portion 1321 accordingly; or, the annular groove 1113 can be provided on the first impeller portion 1321, and the annular protrusion 1112 can be provided on the inner top of the separation chamber 110 accordingly.

[0121] In some embodiments, the sludge storage tank 400 is provided with a negative pressure conduit 520, which is connected to the first accommodating space 111 through a first port 521. To prevent sewage in the sludge storage tank 400 from being accidentally sucked into the impeller motor 131, the negative pressure device 310, or the main unit 300, a gap can be further provided between the first port 521 of the negative pressure conduit 520 and the impeller 132. For example, this gap can refer to the shortest distance from the impeller 132 to the surface of the wall of the first port 521 of the negative pressure conduit 520, and the range of this shortest distance can be 0.5-10 mm.

[0122] For example, the sludge storage tank 500 is provided with a negative pressure conduction pipe 520. The periphery of the first port 521 of the negative pressure conduction pipe 520 is provided with an adapter surface 523. The third impeller portion 1323 includes at least three blades that can be shaped to fit the adapter surface 523. The shortest distance from the edge of the blade that fits the adapter surface 523 to the adapter surface 523 can be 0.5-10mm.

[0123] Understandably, by setting a gap between the first port 521 of the negative pressure conduit 520 and the impeller 132, the accidentally aspirated sewage can be discharged into the first containment space 11. When this gap is too large, the negative pressure generated by the negative pressure device 310 will be difficult to transmit to the sludge storage tank 400, thereby reducing the speed at which sewage enters the sludge storage tank 400 from the separation device 100, and even causing sewage accumulation in the separation device 100, affecting the separation effect of the separation device 100; when this gap is too small or there is no gap, sewage will have difficulty being discharged into the first containment space 11 through the gap, and may even be sucked into the negative pressure device 310, causing electronic malfunctions or even short circuits, affecting the performance and reliability of the negative pressure device 310, and reducing the service life of the negative pressure device 310. It is understandable that by setting blades in the third impeller section 1323 that match the shape of the adapter surface 523, the sewage that is accidentally sucked in by the negative pressure guide pipe 520 can be discharged into the first accommodating space 111 more quickly, and the anti-sucking effect of the gap can be improved.

[0124] In some embodiments, the magnetic component 42 can be disposed on the impeller 32, for example, on the first impeller portion 321. A Hall sensor 143 can be correspondingly disposed on the outer top of the separation chamber 110. The magnetic component 142 and the Hall sensor 143 can be used to measure the rotational speed of the impeller 132 or the installation tightness. Closed-loop control is achieved by measuring the rotational speed of the impeller 132, ensuring the stable and reliable operation of the impeller motor 131. The speed can be automatically or manually adjusted according to the condition of the object to be cleaned, thereby improving the gas-liquid separation efficiency. Fault diagnosis and self-testing can also be performed based on the rotational speed data, reducing maintenance costs and improving the durability and reliability of the cleaning equipment.

[0125] This application provides a sludge storage tank 500, as shown in Figures 1, 16, and 18. The sludge storage tank 500 may include a sludge tank body 510 and a liquid guiding component 535. The liquid guiding component 535 may include a sludge-collecting guide pipe 530 and a buoyancy component. The sludge-collecting guide pipe 530 may be a flexible hose, and the buoyancy component may be disposed at the second opening 532 of the sludge-collecting guide pipe 530. The buoyancy component may include a buoyancy block or a buoyancy ball, so that the second opening 532 of the sludge-collecting guide pipe 530 floats on the liquid surface with the buoyancy component, thereby achieving the effect that the liquid guiding port of the liquid guiding component 535 does not come into contact with the sludge in the sludge storage tank 500 when the cleaning equipment is in any posture.

[0126] Furthermore, the sludge storage chamber 500 may also include a negative pressure conduit 520, wherein the negative pressure conduit 520 is a flexible hose, and the negative pressure conduit 520 can be installed at the top 512 of the sludge chamber 510. The first port 521 of the negative pressure conduit 520 can be connected to an external negative pressure channel, and the second port 522 of the negative pressure conduit 520 can be connected to a buoyancy component. The negative pressure conduit 520 can be used to generate negative pressure within the sludge storage chamber 511. When the sludge storage chamber 500 is not connected to a negative pressure channel or does not include a negative pressure conduit 520, an air vent or a one-way valve can be provided in the sludge chamber 510 to quickly balance the air pressure within the sludge chamber when sludge is rapidly introduced into the sludge chamber, thereby improving the capture efficiency.

[0127] By connecting the buoyancy component to the second port 522 of the negative pressure conduit 520, the second port 522 of the negative pressure conduit 520 is prevented from contacting the sewage in the sewage storage tank 500 when the cleaning equipment is in any position, thus preventing backflow and ensuring the realization of the omnidirectional liquid storage function of the sewage tank. By providing a liquid guiding component 535 to the sewage storage tank 500, the sewage storage tank 500 possesses omnidirectional liquid storage functionality and can be applied to cleaning equipment, allowing the cleaning equipment to be used in any position.

[0128] It can be further understood that when the sludge storage chamber 500 is equipped with a negative pressure conduction pipe 520, since the negative pressure conduction pipe 520 is connected to an external negative pressure channel, it can generate negative pressure in the sludge storage chamber 511, thereby accelerating the collection of sludge and having the advantage of high sludge collection efficiency.

[0129] In some embodiments, referring to Figures 15 to 19, the sludge storage tank 500 may include a sludge tank body 510, a negative pressure conduit 520, and a sludge collection conduit 530. The sludge tank body 510 includes a sludge storage cavity 511. The negative pressure conduit 520 is disposed at the top 512 of the sludge tank body 510. The first port 521 of the negative pressure conduit 520 is connected to the separation device 100, and the second port 522 of the negative pressure conduit 520 is located in the middle region 5111 of the sludge storage cavity 511. The sludge collection conduit 530 is disposed at the top 512 of the sludge tank body 510. The first port 531 of the sludge collection conduit 530 is connected to the capture channel 1131 of the separation device 100, and the second port 532 of the sludge collection conduit 530 is located in the middle region 5111 of the sludge storage cavity 511.

[0130] The range corresponding to the intermediate region 5111 can satisfy the following relationship:

[0131] Wherein, d1 is the diameter or width of the sewage storage chamber 511 of the sewage tank 510, h1 is the height of the sewage storage chamber 511 of the sewage tank 510, d2 is the diameter or width of the middle region 5111 of the sewage storage chamber 511, and h2 is the height of the middle region 5111 of the sewage storage chamber 511.

[0132] Correspondingly, the middle area 5111 can be defined by referring to the shapes of cubes, cylinders, or cuboids.

[0133] It is understandable that when the sludge storage cavity 511 is a square, d1 can be the width of the sludge storage cavity 511 of the sewage tank 510, and d2 can be the width of the middle area 5111 of the sludge storage cavity 511. When the sludge storage cavity 511 is a cylinder or a sphere, d1 can be the diameter of the sludge storage cavity 511 of the sewage tank 510, and d2 can be the diameter of the middle area 5111 of the sludge storage cavity 511. Specifically, the second port 522 of the negative pressure guiding pipe 520 and the second port 532 of the sludge receiving guiding pipe 530 are located at 1 / 6 to 5 / 6 of the distance from one side of the inner wall of the sewage tank 510 to the other side of the inner wall; and / or, the second port 522 of the negative pressure guiding pipe 520 and the second port 532 of the sludge receiving guiding pipe 530 are located at 1 / 6 to 5 / 6 of the distance from the top 512 to the bottom 513 of the sewage tank 510.

[0134] Understandably, there can also be a distance between the second port 522 of the negative pressure conduit 520 or the second port 532 of the contaminant-collecting conduit 530 and the inner wall of the sewage tank 510, so that the maximum liquid storage depth of the omnidirectional liquid storage space 5112 reaches 1.2-25.5 cm, ensuring omnidirectional liquid storage capacity. For example, the shortest distance between the second port 522 of the negative pressure conduit 520 or the second port 532 of the contaminant-collecting conduit 530 and the inner wall of the sewage tank 510 can be 1.2-25.5 cm.

[0135] It is understandable that by limiting the shortest distance range from the second port 522 of the negative pressure guide pipe 520 and the second port 532 of the sludge-collecting guide pipe 530 to the inner wall of the sludge tank 510, or by limiting the range of the intermediate area 5111, the maximum liquid storage depth of the omnidirectional liquid storage space 5112 can be ensured on the basis that the omnidirectional liquid storage function of the sludge storage tank 500 can be realized, thus ensuring the endurance and performance of the cleaning equipment, reducing the frequency of users disassembling and cleaning the sludge storage tank 500, and improving the product user experience.

[0136] In some embodiments, the first port 521 of the negative pressure conduit 520 can be located in the middle of the top 512 of the sewage tank 510, and the first port 531 of the contaminant-collecting conduit 530 can be located at the periphery of the top 512 of the sewage tank 510. Since conventional gas-liquid separation devices 100 often employ centrifugal separation technology, sewage may be thrown to the inner periphery of the sewage separation tank 510, while gas may flow out from the middle, creating negative pressure. Furthermore, to better integrate the sewage storage tank 500 with the conventional gas-liquid separation device 100, the first port 521 of the negative pressure conduit 520 can be located in the middle of the top 512 of the sewage tank 510, and the first port 531 of the contaminant-collecting conduit 530 can be located at the periphery of the top 512 of the sewage tank 510. This not only reduces the flow-guiding structure of the sewage storage tank 500 and the sewage separation tank 510, making the structure more compact, but also improves the separation and contaminant-collecting effects of the cleaning equipment.

[0137] In some embodiments, the pipe portion of the wastewater conduit 530 may include a first pipe section 533 and a second pipe section 534 connected between two pipe openings. At least a portion of the first pipe section 533 may extend from the periphery of the top 512 of the wastewater tank 510 to the negative pressure conduit 520, and at least a portion of the second pipe section 534 may extend along the negative pressure conduit 520 to the central region 5111. By dividing the wastewater conduit 530 into a first section 533 extending from the periphery of the top 512 of the wastewater tank 510 to the negative pressure conduit 520 and a second section 534 extending along the negative pressure conduit 520 to the middle area 5111, the following advantages are achieved: First, it facilitates control of the wastewater flow direction, preventing wastewater from directly flying to the second port 522 of the negative pressure conduit 520, thus avoiding backflow and reduced efficiency; second, it enables wastewater to quickly flow into the middle area 5111 and reach the wastewater storage chamber 511; and third, it allows for a larger omnidirectional liquid storage space 5112 in the wastewater storage chamber 511, ensuring the performance of the wastewater storage tank 500 and the cleaning equipment.

[0138] In some embodiments, the sidewall of the second port 522 of the negative pressure conduit 520 near the contaminant conduit 530 protrudes from the second port 522 of the negative pressure conduit 520.

[0139] For example, the periphery of the second port 522 of the negative pressure conduit 520 may include a first sidewall 5221 and a second sidewall 5222, wherein the first sidewall 5221 may be longer than the second sidewall 5222. The first sidewall 5221 is located closer to the contaminated conduit 530 than the second sidewall 5222.

[0140] Understandably, the longer first sidewall 5221 of the pipe opening prevents the negative pressure channel from directly corresponding to the second opening 532 of the contaminant-collecting guide pipe 530, thus preventing waste liquid from flowing back into the negative pressure guide pipe 520 and ensuring the omnidirectional contaminant-collecting performance, omnidirectional liquid storage performance, and usability of the cleaning equipment of the contaminant storage tank 500. Alternatively, the orientation of the second opening 532 of the contaminant-collecting guide pipe 530 can be opposite to the orientation of the second opening 522 of the negative pressure guide pipe 520, thereby achieving the technical effect of blocking waste liquid.

[0141] Specifically, the second port 532 of the sludge-collecting conduit 530 can be directed toward the side wall 514 of the sewage tank 510, and the second port 522 of the negative pressure conduit 520 can be directed toward the bottom 513 of the sewage tank 510; or the second port 532 of the sludge-collecting conduit 530 can be directed toward the bottom 513 of the sewage tank 510, and the second port 522 of the negative pressure conduit 520 can be directed toward the side wall 514 of the sewage tank 510.

[0142] In some embodiments, a blocking portion 5321 is provided around the second port 532 of the contaminant-collecting conduit 530, and at least a portion of the blocking portion 5321 is located between the second port 532 of the contaminant-collecting conduit 530 and the second port 522 of the negative pressure conduit 520. The blocking portion 5321 may be provided at the second port 532 of the contaminant-collecting conduit 530 or on the inner wall of the sewage tank 510.

[0143] When the blocking part 5321 is provided on one side of the second port 532 of the contaminant-collecting guide pipe 530, the blocking part 5321 can also extend to the other side of the second port 532 of the contaminant-collecting guide pipe 530, thereby preventing splashing and backflow.

[0144] It is understandable that by extending the blocking part 5321 to the other side of the second port 532 of the contaminant-collecting guide pipe 530, a cross-section of the second port 532 of the contaminant-collecting guide pipe 530 can be made to present a "C" shape, thereby preventing splashing and backflow.

[0145] In some embodiments, the wastewater tank 510 may include a cover 540 and a cavity 550. A negative pressure conduit 520 and a sludge collection conduit 530 may be disposed on the cover 540, which is detachably connected to the cavity 550 to form a sludge storage cavity 511. By dividing the wastewater tank 510 into a cover 540 and a cavity 550, and by making the cover 540 detachably connected to the cavity 550, it is convenient for users to disassemble and clean the wastewater tank 510, improving the user experience of the sludge storage tank 500 and the cleaning equipment.

[0146] In some embodiments, referring to Figures 17 and 18, the seal 160 may include a first seal 161 and a second seal 162. Specifically, the cover 540 may be provided with a first closing portion 541, and the cavity 550 may be provided with a second closing portion 551. The first closing portion 541 and / or the second closing portion 551 may be provided with a first seal 161, and the first closing portion 541 may be sealed and connected to the second closing portion 551 through the first seal 161.

[0147] For example, mounting holes can be provided on the first cover portion 541 and / or the second cover portion 551, and an elastic insert can be provided on the first seal 161, so that the first seal 161 can be installed by inserting the elastic insert into the mounting hole. By achieving a sealed connection, the sealing performance at the cover can be improved, leakage problems can be reduced, and the safety of the cleaning equipment can be improved. Through the design of the elastic insert-mounting hole cooperation, on the one hand, the seal 160 can be prevented from shifting, so that when the user disassembles and assembles the cover 540 and the cavity 550 to clean the sludge storage tank 500, there is no need to disassemble and assemble the seal 160 again, thereby ensuring the sealing and convenience of the user's installation. On the other hand, it can facilitate the installation of irregularly shaped seals 160, which not only enhances the sealing performance, but also makes it possible to diversify the design of the sludge storage tank 510 of the sludge storage tank 500.

[0148] Furthermore, a mounting hole can be provided at the top of the cover 540, and an elastic insert can be provided in the second seal 162, allowing the elastic insert to be inserted into the mounting hole to install the second seal 162. When the sludge storage tank 500 is used in conjunction with cleaning equipment or separation device 100, the second seal 162 can improve the sealing performance at the joint, thereby reducing leakage and improving the safety of the cleaning equipment. Because it is installed through the mounting hole-elastic insert method, the second seal 162 can be irregularly shaped, thus better fitting the joint, making the cleaning equipment structure more compact, improving the sealing effect, and fixing it at the joint. Users do not need to disassemble and reassemble the seal 160 during cleaning, making it easier and simpler to use.

[0149] In some embodiments, please refer to FIG8, the seal 160 may further include a third seal 163, and a bevel 1153 may be provided at the periphery of the fourth channel opening 1152, the bevel 1153 being used to place the seal 160.

[0150] In some embodiments, referring to Figures 6 and 18, the periphery of the first port 521 of the negative pressure conduction pipe 520 may be provided with an adapter surface 523. The adapter surface 523 may be an arc surface or a rounded surface, and the first port 521 of the negative pressure conduction pipe 520 may correspond to the impeller 132. The impeller 132 may include at least three blades that can be shaped to fit the adapter surface 523.

[0151] It is understandable that by setting an adapter surface 523 around the first port 521 of the negative pressure conduction pipe 520, pressure energy loss can be reduced, noise or fluid heat loss can be reduced, and it can be adapted to the devices that may be set in the traditional gas-liquid separation device 100, such as the impeller 132, so that the accidentally aspirated fluid can be directly reintroduced into the separation sewage chamber 510 by centrifugation through the impeller 132, preventing sewage from flowing back and being aspirated into the negative pressure channel.

[0152] This application also proposes a cleaning device, as shown in Figures 1, 4, 11, 12, 13, 18, and 19. The cleaning device may include a separation device 100, a liquid storage tank 300, a brush head device 200, and a sludge storage tank 500. The separation device 100 can be connected to the main unit 400. The separation device 100 may include a separation chamber 110 and a capture column 113. The separation chamber 110 may include a first accommodating space 111. The capture column 113 is formed on the side wall of the separation chamber 110 and may include a capture channel 1131 communicating with the first accommodating space 111.

[0153] The liquid storage tank 300 may include a liquid storage shell 310, which is recessed to form an adapter groove 313. When the liquid storage tank 300 is adapted to the separation device 100, the separation device 100 is at least partially housed in the adapter groove 313. The liquid storage shell 310 is provided with a vent 315. An air bladder may be disposed in the liquid storage cavity 317 of the liquid storage shell 310 and connected to the outside air through the vent 315. The brush head device 200 may be used to clean the surface to be cleaned. The brush head device 200 may include a water suction port 210, which may be used to suck up the wastewater from the surface to be cleaned. The sludge storage tank 500 may include a sludge tank body 510, a negative pressure conduit 520, and a sludge collection conduit 530. The sludge tank body 510 may include a sludge storage cavity 511. The negative pressure conduit 520 may be located at the top 512 of the sludge tank body 510. The first port 521 of the negative pressure conduit 520 is connected to the separation device 100, and the second port 522 of the negative pressure conduit 520 is located in the middle region 5111 of the sludge storage cavity 511. The sludge collection conduit 530 may be located at the top 512 of the sludge tank body 510. The first port 531 of the sludge collection conduit 530 is connected to the capture channel 1131 of the separation device 100, and the second port 532 of the sludge collection conduit 530 is located in the middle region 5111 of the sludge storage cavity 511.
