Description

Technical Field

[0001] The present disclosure relates to the field of smart home technology, and in particular to a sewage tank, cleaning equipment, and a cleaning system. Background Art

[0002] As society continues to develop and people's living standards improve, cleaning equipment (such as floor scrubbers and sweepers) are becoming more time-saving and labor-saving than traditional manual cleaning, and are being used by more and more families. Cleaning equipment typically consists of a body and a cleaning base. The cleaning base includes a cleaning head for mopping, which rotates at high speed to clean the floor.

[0003] Typically, a floor scrubber is equipped with a wastewater tank to collect wastewater from the floor.

[0070] The embodiment of the present disclosure provides a cleaning device, such as Figure 1As shown, the cleaning device 10 is, for example, a floor scrubber. It should be noted that the present disclosure's explanation of the cleaning device through a floor scrubber is merely a preferred embodiment of the present disclosure and does not limit the scope of protection of the cleaning device of the present disclosure. For example, the cleaning device of the present disclosure may be a handheld floor scrubber with a handle and manually operated by a user, or an autonomously movable floor scrubbing robot with drive wheels that can control the movement of the drive wheels and the cleaning rollers to clean the floor according to a program stored in the robot. For another example, the cleaning device of the present disclosure may also be other cleaning devices such as a mop, a sweeper, or an electric mop.

[0071] Below, the present disclosure is described in detail by taking the cleaning device 10 as a handheld floor scrubber as an example.

[0072] Specifically, if Figure 1 As shown, the handheld floor scrubber includes a body 100 and a cleaning base 200. The body 100 includes a first end and a second end along its length, and the cleaning base 200 is connected to the second end of the body 100. The body 100 is provided with a handle assembly 140, which is connected to the first end of the body 100 away from the cleaning base 200 and is used for operation by the user. By gripping the handle assembly 140, the user controls the cleaning base 200 to move across the surface to be cleaned, thereby achieving the purpose of cleaning the surface to be cleaned.

[0073] Among them, the cleaning base 200 is hinged to the body 100, such as a pivot connection, a ball head connection, etc.; when the user holds the handle assembly 140 to control the cleaning base 200 to move on the surface to be cleaned, by hingedly connecting the cleaning base 200 to the body 100, the relative angle between the body 100 and the cleaning base 200 can be adjusted, thereby changing the operating angle and flexibly adjusting the cleaning posture to facilitate the cleaning operation.

[0074] Among them, such as Figure 1 As shown, the main body 110 of the machine 100 is equipped with a clean water tank 120 and a dirty water tank 130. When the cleaning head on the cleaning base 200 of the floor scrubber is mopping the floor, the clean water tank 120 cooperates with the liquid supply assembly to provide cleaning liquid to the cleaning head to mop the floor. The dirty water tank 130 is configured to store dirty water. The dirty water generated during mopping and debris collected during mopping are drawn into the dirty water tank 130 through a negative pressure device through a sewage suction channel. The dirty water, debris, and gas are then separated in the dirty water tank 130. Therefore, the air-water separation effect in the dirty water tank 130 is particularly important.

[0075] In this regard, the embodiment of the present disclosure provides a sewage tank, such as Figures 2 to 5As shown, the sewage tank 130 includes a box body 131 and a separation assembly 132, the box body 131 is formed with a receiving space 1311; the box body 131 is provided with an open end 1313 of the receiving space 1311 at the top along the height direction Z, and the bottom of the box body 131 is provided with a sewage inlet 1312; at least part of the separation assembly 132 is located in the receiving space 1311, and the separation assembly 132 is formed in the receiving space 1311 with a first air duct 13241, a second air duct 13242 and a third air duct 13243, the first air duct 13241 is provided with a second air duct 13242 and a third air duct 13243, and the first air duct 13241 is provided with a second air duct 13242 and a third air duct 13243. The inlet of 3241 is connected with the sewage inlet 1312, the outlet of the first air duct 13241 is located on the side close to the top and is connected with the inlet of the second air duct 13242, and the outlet of the second air duct 13242 is located on the side close to the bottom and is connected with the accommodating space 1311; the inlet of the third air duct 13243 is located on the side close to the bottom and is connected with the accommodating space 1311, and the outlet of the third air duct 13243 is located on the side close to the top and is used to connect the negative pressure device of the cleaning equipment 10, which may be a fan, for example.

[0076] The sewage tank 130 provided by the present disclosure has a separation component 132 forming a first air duct 13241, a second air duct 13242 and a third air duct 13243 in the accommodation space 1311; the sewage entering the sewage tank 130 through the sewage inlet 1312 passes through the first air duct 13241 and the second air duct 13242, because the outlet of the first air duct 13241 is located on the side close to the top and is connected to the inlet of the second air duct 13242, and the outlet of the second air duct 13242 is located on the side close to the bottom and is connected to the accommodation space 1311. 11 is connected, that is, after the sewage is drawn up from the first air duct 13241 through the sewage inlet 1312, the sewage is turned 180 degrees through the first air duct 13241 and the second air duct 13242, so that the sewage moves downward and falls to the bottom of the sewage tank 130; the gas is turned upward through the third air duct 13243, so that the movement directions of the sewage and the gas are reversed by 180 degrees, thereby greatly improving the gas-water separation effect, reducing the amount of water vapor entering the fan, improving the safety of the fan, and increasing the service life of the fan.

[0077] In some embodiments, as Figures 5 to 8 As shown, the separation assembly 132 includes: a separation bracket 1321, the separation bracket 1321 includes a mounting portion 13211 and an air duct portion 13212, the separation bracket 1321 is assembled on the open end 1313 of the sewage tank 130 through the mounting portion 13211, a second air duct 13242 is formed on the air duct portion 13212, and a third air duct 13243 is formed by the air duct portion 13212 and the side wall of the sewage tank 130.

[0078] The assembly of the separation component 132 and the box body 131 is realized through the installation part 13211, so that the air duct part 13212 of the separation component 132 is extended into the accommodating space 1311 through the production end of the box body 131; the second air duct 13242 is directly formed by the air duct part 13212, and the third air duct 13243 is formed by the air duct part 13212 and the side wall of the sewage tank 130, that is, the third air duct 13243 is formed by utilizing the original other structures. The formed third air duct 13243 can have a larger area of the air duct, thereby improving the smoothness of the third air duct 13243, thereby improving the gas-water separation effect.

[0079] In some embodiments, as Figures 5 to 8 As shown, the air duct portion 13212 includes an air guide pipe 132120, which forms a second air duct 13242. The air guide pipe 132120 forms the second air duct 13242, which reduces the volume of the second air duct 13242 in the receiving space 1311 and improves the drainage effect of sewage.

[0080] Among them, such as Figures 5 to 8 As shown, air duct 132120 includes an air duct body 132121 and an elbow 132122. The outlet of elbow 132122 is sealedly connected to air duct body 132121, and the inlet of elbow 132122 is connected to the outlet of first air duct 13241. Elbow 132122 and air duct body 132121 form a second air duct 13242. Second air duct 13242 forms a first 90° turn at elbow 132122, and a second 90° turn at the location on air duct body 132121 where it connects to elbow 132122. This allows sewage entering first air duct 13241 to achieve a 180° turn through second air duct 13242.

[0081] The air duct body 132121 and the elbow 132122 can be detachably connected by means of threaded connection, snap connection, etc., and a first sealing ring 132123 can be further provided between the connection point of the air duct body 132121 and the elbow 132122 to improve the sealing performance of the connection between the air duct body 132121 and the elbow 132122, thereby preventing sewage from leaking from the connection point or air leakage at the connection point, thereby reducing the gas-water separation effect. Of course, the air duct body 132121 and the elbow 132122 can also be fixedly connected by means of bonding, welding, etc., and the air duct body 132121 and the elbow 132122 can also be an integrally formed structure, which is not limited in this disclosure.

[0082] Extensions 132125 are formed on both sides of the air duct 132120 of the separation bracket 1321. These extensions 132125 are in sealed contact with the sidewalls 1315 of the housing 131, thereby forming a third air duct 13243. Rubber seals may be provided between the extensions 132125 and the sidewalls 1315 of the housing 131 to enhance the sealing effect between the extensions 132125 and the sidewalls 1315.

[0083] In some embodiments, as Figure 5 As shown, the air duct portion 13212 also includes a sewage inlet pipe 1322, which is formed with a first air duct 13241. The inlet of the sewage inlet pipe 1322 is connected to the sewage inlet port 1312 on the housing 131, and the inlet of the air guide duct 132120 is sealed and plugged into the outlet of the sewage inlet pipe 1322. The first air duct 13241 formed by the sewage inlet pipe 1322 cooperates with the second air duct 13242 of the air duct portion 1321 on the separation bracket 1321 to achieve a 180-degree diversion of the sewage, causing it to move downward and fall to the bottom of the sewage tank 130. The sealed plug-in connection between the sewage inlet pipe 1322 and the separation bracket 1321 facilitates removal of the separation bracket 1321 from the sewage tank 130 to pour the sewage from the sewage tank 130 out of the open end 1313.

[0084] When the air duct 132120 includes the air duct body 132121 and the elbow 132122, the elbow 132122 and the water inlet pipe can be connected together by plugging. The provision of the elbow 132122 facilitates adjustment of the plugging direction of the elbow 132122 and the water inlet pipe, so that the plugging direction of the elbow 132122 and the water inlet pipe is along the height direction Z of the housing 131, thereby facilitating removal of the separation bracket 1321 from the housing 131.

[0085] Among them, such as Figure 5 As shown, when the elbow 132122 is plugged into the water inlet pipe, the outlet end of the water inlet pipe can be located inside the inlet end of the elbow 132122. Since the elbow 132122 acts as an active component connected to the water inlet pipe when plugged into the water inlet pipe, the inlet end of the elbow 132122 is designed to be larger, making it easier for the elbow 132122 to be sleeved onto the water inlet pipe, thereby facilitating the assembly of the separation bracket 1321 on the box body 131.

[0086] Among them, when the elbow 132122 is connected to the water inlet pipe, a second sealing ring 132124 can be set between the elbow 132122 and the water inlet pipe to improve the sealing performance after the elbow 132122 and the water inlet pipe are connected, so as to prevent sewage from leaking from the connection position or air leakage at the connection position, thereby reducing the gas-water separation effect. Among them, the second sealing ring 132124 can be set on the inner wall of the elbow 132122 that is connected to the water inlet pipe, or the second sealing ring 132124 can be set on the outer wall of the water inlet pipe that is connected to the elbow 132122; when the second sealing ring 132124 is set on the elbow 132122, the second sealing ring 132124 can be clamped with the elbow 132122 by elastic force. For example, the second sealing ring 132124 is provided with multiple positioning protrusions, and the elbow 132122 is provided with multiple positioning holes. The second sealing ring 132124 is set on the inner wall of the elbow 132122, and the multiple positioning protrusions are located in the multiple positioning holes, so that the second sealing ring 132124 is positioned and clamped on the elbow 132122; it is beneficial for the second sealing ring 132124 to be replaced after long-term use or when sealing failure occurs.

[0087] In some embodiments, as Figure 5 As shown, in the height direction Z, the outlet of the second air duct 13242 and the inlet of the third air duct 13243 can be at the same height. By aligning the outlet of the second air duct 13242 and the inlet of the third air duct 13243 at the same height, when the sewage and gas are discharged through the outlet of the second air duct 13242, the gas can make a 180-degree turn in time and be discharged upward through the third air duct 13243, thereby improving the gas-water separation effect.

[0088] In some embodiments, as Figures 5 to 8 As shown, the sewage tank 130 further includes an upper cover 133, which is fixedly connected to the mounting portion 13211. The upper cover 133 is connected to the separation assembly 132 to form a blockage for the same open end 1313.

[0089] Among them, a switch assembly 137 can be provided on the upper cover 133 to form a switch connection between the sewage tank 130 and the main body 110; for example, a push-type switch assembly 137 can be provided to form a switch connection between the sewage tank 130 and the main body 110, thereby facilitating the disassembly and assembly of the sewage tank 130.

[0090] In some embodiments, as Figure 9 and Figure 10 As shown, the box body 131 includes a bottom plate 1314 and a side wall 1315 . The bottom plate 1314 and the side wall 1315 enclose a receiving space, and the sewage inlet 1312 is provided on the bottom plate 1314 .

[0091] In the width direction X of the housing 131, the sewage inlet pipe 1322 is arranged close to the side wall of one side of the sewage tank 130, and the outlet of the sewage inlet pipe 1322 is arranged obliquely toward the other side wall of the sewage tank 130. When the sewage tank 130 is full of sewage, the sewage accumulated in the housing 131 needs to be poured out through the open end 1313. Since the sewage inlet port 1312 of the housing 131 is fixedly connected to the sewage inlet pipe 1322, when pouring water from the rear side of the housing 131, there is a phenomenon of sewage backflowing from the sewage suction port, causing the sewage to flow out of the sewage inlet port 1312 at the bottom of the housing 131, which can easily soil the user's shoes and clothes, seriously affecting the user's experience. In the present disclosure, the outlet of the sewage inlet pipe 1322 is tilted toward the side wall on the opposite side of the sewage tank 130, so that the outlet of the sewage inlet pipe 1322 can be completely maintained above the liquid level, thereby preventing sewage from flowing out of the sewage inlet port 1312 at the bottom of the tank body 131, thereby improving the user experience.

[0092] Among them, such as Figure 10 As shown, the angle ∠A between the plane where the outlet of the sewage inlet pipe 1322 is located and the central axis of the sewage inlet pipe 1322, that is, the angle ∠A at which the outlet is inclined toward the side wall on the other side opposite to the sewage tank 130, can be 20° to 60°, so that the outlet of the sewage inlet pipe 1322 can be completely maintained above the liquid level without affecting the smoothness of the air duct formed after the connection with the elbow 132122. ∠A is, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., which are not listed one by one in the present disclosure; of course, ∠A can also be less than 20° or greater than 60°, and the present disclosure does not impose any limitation on this.

[0093] The sewage inlet pipe 1322 and the housing 131 can be an integrally formed structure to enhance the structural strength of the sewage inlet pipe 1322, thereby enhancing the sealing performance when the sewage inlet pipe 1322 is plugged into the elbow 132122. Of course, the sewage inlet pipe 1322 and the housing 131 can also be a separate structure, for example, connected together by bonding, welding, threaded connection, clamping, etc., which is not limited in this disclosure.

[0094] In some embodiments, the sewage tank 130 is provided with a grab assembly 136, which is located on the side wall of the tank body 131 opposite to the sewage inlet pipe 1322. The grab assembly 136 is provided to facilitate lifting the tank body 131 and pouring out the sewage from the rear side of the tank body 131.

[0095] Among them, the grabbing assembly 136 may include a grabbing plate, which is connected to the box body 131 through an elastic member; when the grabbing plate is not grabbed, the grabbing plate is in its original position through the elastic member; when the grabbing plate is in its original position, it can be basically flush with the outer surface of the box body 131 to avoid the protrusion of the grabbing plate from easily hanging foreign objects, while improving the appearance of the sewage tank 130; when the user lifts the sewage tank 130 through the grabbing plate, the bottom of the grabbing plate can be rotated toward the outside of the box body 131 to increase the grabbing space and facilitate the user to apply force; when the user releases the grabbing plate, the grabbing plate can return to its original position through the elastic restoring force of the elastic member.

[0096] In some embodiments, as Figure 9 and Figure 10 As shown, in the width direction X of the box body 131, the sewage inlet pipe 1322 is arranged close to the side wall of one side of the sewage tank 130; at least a portion of the sewage inlet pipe 1322 extending from the sewage inlet port 1312 toward the outlet side of the sewage inlet pipe 1322 has an accommodating space 1311 only between the side wall on the other side opposite to the sewage tank 130.

[0097] By ensuring that at least a portion of the sewage inlet pipe 1322 extending from the sewage inlet port 1312 toward the outlet side of the sewage inlet pipe 1322 has an accommodating space 1311 only between the side wall on the other side opposite to the sewage tank 130, and at least a portion of the sewage inlet pipe 1322 extending from the sewage inlet port 1312 toward the outlet side of the sewage inlet pipe 1322 is not provided with an accommodating space 1311 on one side, it is avoided that debris is trapped in the narrow space and cannot be removed, thereby avoiding the phenomenon of users manually removing debris, thereby improving the user experience.

[0098] Among them, when the sewage inlet pipe 1322 and the box body 131 can be an integrally formed structure, at least a portion of the pipe body of the sewage inlet pipe 1322 extending from the sewage inlet port 1312 toward the outlet side of the sewage inlet pipe 1322 can be used as the side wall of the box body 131, so that part of the outline of the sewage inlet pipe 1322 can be displayed from the outer outline of the box body 131, and the position of the sewage inlet pipe 1322 reflected in the box body 131 can be an atypical structure; this structure can be matched with the positioning structure on the body body 110 to form the positioning of the sewage tank 130 assembled on the body body 110, so as to improve the assembly accuracy of the sewage tank 130.

[0099] In some embodiments, as Figures 11 to 13 As shown, the separation component 132 also includes: a filter element 1323, which is arranged in the accommodating space 1311 and divides the accommodating space 1311 into a first accommodating space 13111 and a second accommodating space 13112 along the height direction Z. An avoidance gap 13234 is provided on the filter element 1323, and the sewage inlet pipe 1322 is located in the avoidance gap 13234.

[0100] The filter element 1323 filters solid debris from the sewage, preventing it from clogging the sewage outlet when the sewage is being poured. The avoidance notch 13234 on the filter element 1323, in conjunction with the sewage inlet pipe 1322, filters solid debris, preventing it from entering the second storage space 13112 below the filter element 1323.

[0101] The filter element 1323 is connected to the separation bracket 1321 , and the filter element 1323 can be taken out simultaneously with the separation bracket 1321 to pour out the filtered debris.

[0102] Among them, a connecting rod 13235 is provided on the filter element 1323, and the filter element 1323 is connected to the separation bracket 1321 through the connecting rod 13235; the connecting rod 13235 and the separation bracket 1321 are detachably connected, for example, the connecting rod 13235 and the separation bracket 1321 are detachably connected by means of threaded connection, clamping, etc.; of course, the connecting rod 13235 and the separation bracket 1321 can also be fixedly connected by means of bonding, welding, etc., and the present disclosure does not impose any restrictions on this.

[0103] In some embodiments, as Figures 11 to 13 As shown, the filter element 1323 includes a first filter portion 13231 corresponding to the second air duct 13242 and a second filter portion 13232 corresponding to the third air duct 13243. In the height direction Z, the first filter portion 13231 is arranged closer to the bottom of the housing 131 relative to the second filter portion 13232. By arranging the first filter portion 13231 closer to the bottom of the housing 131 relative to the second filter portion 13232, the filter element 1323 can accommodate more solid debris.

[0104] Among them, a baffle 1316 is provided on the inner wall of the box body 131. The baffle 1316 cooperates with the first filter part 13231, the second filter part 13232 and the sewage inlet pipe 1322 to completely shield the box body 131 from the cross section, so that sewage can only enter the second accommodating space 13112 below through the filter holes on the filter part, thereby improving the filtering effect of solid debris.

[0105] Among them, a third sealing ring can also be set on the part where the filter element 1323 contacts the inner wall of the box body 131 to reduce the gap between the contact position of the filter element 1323 and the inner wall of the box body 131 and improve the filtering capacity; at the same time, when the filter element 1323 is removed, the third sealing ring can be used to scrape off the dirt on the inner wall of the box body 131 to improve the cleanliness of the box body 131.

[0106] In some embodiments, as Figure 12 and Figure 13As shown, the first filter portion 13231 is flat. By making the first filter portion 13231 flat, that is, the side of the first filter portion 13231 near the sewage inlet pipe 1322 is not blocked, forming a semi-open structure, debris accumulated on the filter portion is more easily poured out from the filter element 1323. Of course, the first filter portion 13231 can also have a cylindrical structure, and this disclosure is not limited to this.

[0107] Among them, such as Figure 12 and Figure 13 As shown, side baffles 13233 may be provided on both sides of the first filter portion 13231 to cooperate with the flat-plate-shaped first filter portion 13231 to form a shovel-shaped structure to better accommodate accumulated debris.

[0108] In some embodiments, as Figure 14 As shown, the separation assembly 132 further includes a first air-water separator 134, which is disposed in the third air duct 13243. By disposing the first air-water separator 134 in the third air duct 13243, air and water can be directly separated in the air duct of the sewage tank 130, further improving the air-water separation effect.

[0109] Among them, such as Figure 14 As shown, the first gas-water separator 134 is provided with a plurality of filtering micropores distributed in a row, gas can pass through the micropores, and the moisture in the gas can be blocked by the micropores to form an effective separation of gas and water.

[0110] The first gas-water separator 134 is detachably connected to the separation bracket 1321. For example, it can be detachably connected to the separation bracket 1321 by a screw or by a snap connection, so as to facilitate the assembly, disassembly and maintenance of the first gas-water separator 134.

[0111] The first gas-water separator 134 may be arranged obliquely in the third air duct 13243 to relatively increase the area of the gas-water separation portion on the first gas-water separator 134 and enhance the gas-water separation capability.

[0112] In some embodiments, as Figure 15 and Figure 16 As shown, the separation assembly 132 further includes a second air-water separator 135, which is disposed at the outlet of the third air duct 13243. The second air-water separator 135 cooperates with the first air-water separator 134 to form a two-stage filtration, thereby improving the air-water separation effect. When the second air-water separator 135 is, for example, a HEPA (High Efficiency Particulate Air Filter) filter, the service life of the second air-water separator 135 can be increased.

[0113] The second gas-water separator 135 is detachably connected to the cover plate, for example, by snapping or screwing, to facilitate assembly, disassembly, and maintenance of the second gas-water separator 135 .

[0114] The second gas-water separator 135 may be arranged obliquely at the outlet of the third air duct 13243 to relatively increase the area of the gas-water separation portion on the second gas-water separator 135 and enhance the gas-water separation capability.

[0115] The present disclosure also provides a cleaning system. Figure 17 and Figure 18 As shown, the cleaning system includes a base station 20 and the cleaning device 10 provided in the above embodiment. The base station 20 is used to park the cleaning device 10. The cleaning device 10 can perform functions such as parking, charging, self-cleaning, sewage discharge, and water replenishment on the base station 20. The beneficial effects of the cleaning system provided by the present disclosure can be found in the detailed discussion of the above cleaning device embodiments and will not be repeated here.
