[0074] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0077] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0078] The liquid tank structure and cleaning equipment provided in the embodiments of the present application, as well as the water filter element 202 and the liquid detection element 60 in the liquid tank structure are now described.

[0079] See also Figures 1 to 10 ,as well as Figure 21 to Figure 31 As shown, the liquid box structure provided in the embodiment of the present application is provided with a liquid collecting chamber 105, a liquid collecting channel 30 and an air extraction channel 40. The liquid collecting channel 30 has an interconnected liquid inlet 301 and a liquid outlet 302, and the height of the liquid outlet 302 is higher than the height of the liquid inlet 301. The liquid collecting chamber 105 has a maximum liquid level line, and the height of the liquid outlet 302 is higher than the maximum liquid level line; the air extraction channel 40 has an interconnected air inlet 401 and an air outlet 402, and the air inlet 401 is arranged between the liquid outlet 302 and the maximum liquid level line in the height direction. The air extraction channel 40 provides suction wind directed from the air inlet 401 to the air outlet 402, and the suction wind is used to suck liquid from the liquid inlet 301 to the liquid outlet 302, and when the liquid falls from the liquid outlet 302 to the liquid collecting chamber 105, it is separated from the liquid and enters the air inlet 401.

[0080] In the liquid tank structure provided in the embodiment of the present application, the height of the liquid outlet 302 of the liquid collecting channel 30 is higher than the height of the liquid inlet 301. Through the wind force applied by the suction wind, the external liquid can enter the liquid collecting channel 30 from the liquid inlet 301 and be transported upward along the height direction to the liquid outlet 302. The height of the liquid outlet 302 is higher than the highest liquid level line of the liquid collecting chamber 105. Through the wind force applied by the suction wind and / or the dead weight of the liquid, the liquid enters the liquid collecting chamber 105 downward along the height direction from the liquid outlet 302. Since the air inlet 401 of the air suction channel 40 is arranged between the liquid outlet 302 and the highest liquid level line along the height direction, when the liquid falls from the liquid outlet 302 to the liquid collecting chamber 105, the suction wind separates from the liquid and enters the air inlet 401. During this process, the suction direction of the suction wind changes relative to the direction in which the liquid enters the liquid collecting chamber 105. The liquid falls into the liquid collecting chamber 105 due to its own weight inertia and is not easily brought into the suction channel 40 by the suction wind, thereby avoiding the problem of liquid entering the motor and causing damage to the electrode.

[0081] In some embodiments, the liquid collecting channel 30 is extended in the height direction, and the liquid inlet 301 and the liquid outlet 302 are arranged opposite to each other in the height direction. The liquid collecting chamber 105 is arranged beside or around a part of the liquid collecting channel 30, and another part of the liquid collecting channel 30 is arranged above the liquid collecting chamber 105.

[0082] The liquid inlet 301 and the liquid outlet 302 are arranged opposite to each other in the height direction, and the sewage generated by the cleaning equipment when cleaning the ground can be directly transported upward to the liquid outlet 302 in the height direction, making the sewage collection path more convenient. The liquid collecting chamber 105 is arranged on the side or around a part of the liquid collecting channel 30, and another part of the liquid collecting channel 30 is arranged above the liquid collecting chamber 105. Part of the liquid collecting channel 30 is integrated in the liquid collecting chamber 105 to further improve the integration.

[0083] More importantly, the liquid collecting channel 30 is arranged along the height direction, and the external liquid is transported upward along the height direction. After flowing out of the liquid outlet 302, the direction of the liquid changes by approximately 1° and then falls downward along the height direction. The sharp turn of the liquid is more conducive to the liquid falling from the liquid outlet 302 and entering the liquid collecting chamber 105, thereby increasing the inertia of the liquid entering the liquid collecting chamber 105, reducing the probability of the liquid being carried away by the suction wind, further reducing the liquid content in the suction wind, and reducing the probability of the motor being damaged.

[0084] In other embodiments, the liquid collecting channel 30 may also be arranged at an angle to the height direction, and the liquid is transported from bottom to top at an inclined angle. The liquid collecting channel 30 may also be arranged beside the liquid collecting chamber 105 without being partially integrated in the liquid collecting chamber 105 .

[0085] Reference Figure 21 to Figure 31As shown, in some embodiments, the liquid tank structure further includes a first partition 2012e, which extends in the height direction and isolates the liquid collecting channel 30 and the air extraction channel 40 on both sides thereof in the first direction, wherein the first direction is perpendicular to the height direction. The air inlet 401 includes a first air inlet 4011 and a second air inlet 4012, wherein the first air inlet 4011 is arranged on the side where the liquid collecting channel 30 is located, and the second air inlet 4012 is arranged on the side where the air extraction channel 40 is located, and the first air inlet 4011 and the second air inlet 4012 are respectively connected to the liquid collecting chamber 105. The liquid collecting chamber 105 has an air passage 80, which is located between the first air inlet 4011, the second air inlet 4012 and the highest liquid level line, and the suction air flows through the liquid outlet 302, the first air inlet 4011, the air passage 80, the second air inlet 4012 and the air extraction channel 40 in sequence.

[0086] By setting the first partition 2012e, the first partition 2012e completely isolates the part of the liquid collecting channel 30 located above the liquid collecting chamber 105 from the exhaust channel 40, and is connected to the air passage 80 inside the liquid collecting chamber through the first air inlet 4011 arranged on the side where the liquid collecting channel 30 is located and the second air inlet 4012 arranged on the side where the exhaust channel 40 is located. In this way, the path of the liquid flowing out of the liquid outlet 302 falling into the liquid collecting chamber 105 and the path of the suction wind passing through the first air inlet 4011 and the air passage 80 are obviously separated, which is more conducive to the separation between gas and liquid.

[0087] It should be noted that the shape, size, and number of the first air inlet 4011 and the second air inlet 4012 can be specifically designed according to the needs of the specific cleaning equipment. The shapes of the first air inlet 4011 and the second air inlet 4012 can be regular or irregular. The first air inlet 4011 can be one or more. The second air inlet 4011 can be one or more. When the first air inlet 4011 and the second air inlet 4012 are multiple, the first air inlet 4011 and the second air inlet 4012 can be arranged in sequence along the first direction.

[0088] Reference Figures 1 to 17 As shown, in some embodiments, the liquid tank structure also includes a second partition 2012a, the second partition 2012a is extended along the height direction, the second partition 2012a and the liquid collecting chamber 105 are spaced along the height direction to form an air inlet 401, and part of the liquid collecting channel 30 and the exhaust channel 40 are arranged on both sides of the second partition 2012a and the air inlet 401 along the first direction, and the first direction is perpendicular to the height direction.

[0089] By setting the second partition 2012a, the second partition 2012a isolates the part of the liquid collecting channel 30 located above the liquid collecting chamber 105 from the exhaust channel 40, so that the path of the liquid flowing out of the liquid outlet 302 to the liquid collecting chamber 105 and the path of the suction air are obviously separated by the second partition 2012a, which is more conducive to the separation of gas and liquid. Among them. The second partition 2012a and the liquid collecting chamber 105 are spaced in the height direction to form an air inlet 401, that is, the air inlet 401 is arranged closer to the liquid collecting chamber 105, so that it is more conducive to using wind power to bring the liquid from the liquid outlet 302 to the top of the liquid collecting chamber 105, and then the wind changes direction through the air inlet 401 and separates from the liquid, thereby improving the utilization of wind power, and the effect of gas-liquid separation is best here, which is conducive to further reducing the probability of motor damage.

[0090] In other embodiments, the design position of the air inlet 401 can be separated from the liquid collecting chamber 105 by a certain distance in the height direction. For example, under the premise that the liquid collecting channel 30 and the second partition plate 2012a are not in contact, the air inlet 401 can be set in the center of the second partition plate 2012a, or in the lower center.

[0091] It should be noted that the shape, size, and number of the air inlet 401 can be specifically designed according to the needs of the specific cleaning equipment. The shape of the air inlet 401 can be regular or irregular. The air inlet 401 can be one or more. When there are multiple air inlets 401, the multiple air inlets 401 can be arranged in sequence along the height direction, and the multiple air inlets 401 can also be arranged in sequence along the circumferential direction of the liquid collection channel 30. The multiple air inlets 401 can be arranged at the same height, for example, they are all arranged close to the liquid collection chamber 105.

[0092] In some embodiments, the first partition plate 2012e or the second partition plate 2012a is in contact with the portion opposite to the liquid collecting channel 30, and the path for the liquid to fall from the liquid outlet 302 to the liquid collecting chamber 105 is located on the side of the liquid collecting channel 30 that is not in contact with the first partition plate 2012e or the second partition plate 2012a. For example, the first partition plate 2012e or the second partition plate 2012a is provided with an adapting recessed area 2012b, and a portion of the liquid collecting channel 30 is accommodated in the adapting recessed area 2012b. The adapting recessed area 2012b is conducive to positioning the liquid collecting channel 30, so that the liquid collecting channel 30 is well fitted with the first partition plate 2012e or the second partition plate 2012a.

[0093] The liquid collecting channel 30 is in close contact with the first partition 2012e or the second partition 2012a, so that the path for the liquid to fall from the liquid outlet 302 to the liquid collecting chamber 105 can only be located at the part away from the first partition 2012e or the second partition 2012a, and the path for the liquid to fall from the liquid outlet 302 to the liquid collecting chamber 105 is further isolated from the path of the suction air, that is, the horizontal distance between the path for the liquid to fall from the liquid outlet 302 to the liquid collecting chamber 105 and the exhaust channel 40 is increased, so that the suction air and the path for the liquid to fall from the liquid outlet 302 to the liquid collecting chamber 105 run horizontally for a certain distance before reaching the exhaust channel 40, thereby further filtering out the liquid in the suction air, further improving the efficiency and effect of gas-liquid separation, and helping to further reduce the probability of the motor being damaged.

[0094] In other embodiments, the liquid collecting channel 30 may also be spaced apart from the first partition plate 2012e or the second partition plate 2012a, and the spacing distance may be larger or smaller. The path for the liquid to fall from the liquid outlet 302 into the liquid collecting chamber 105 may be located in the entire circumference of the liquid collecting channel 30, thereby increasing the unit flow rate of the liquid falling into the liquid collecting chamber 105 and improving the liquid collection efficiency.

[0095] In some embodiments, the liquid box structure further includes a plurality of baffles 50 , which are disposed on the channel wall of the exhaust channel 40 and are sequentially spaced along the extension direction of the exhaust channel 40 . The plurality of baffles 50 allow the suction air to flow through the exhaust channel 40 .

[0096] For example, multiple baffles 50 can be set on the side wall of the same side of the exhaust channel 40, or multiple baffles 50 can be randomly set on different side walls on different sides. When the suction air flows through the multiple baffles 50, the liquid in the gas is filtered out through friction and obstruction between the multiple baffles 50, thereby further improving the efficiency and effect of gas-liquid separation, which helps to further reduce the probability of damage to the motor.

[0097] In other embodiments, the number of baffles 50 may also be one. For example, the baffle 50 is a plate structure with one or more holes in the middle. Through the hole in the middle, or multiple holes on the baffle 50, gas can pass through and filter the liquid to achieve gas-liquid separation.

[0098] It should be noted that the shape, size, and number of the baffle 50 can be specifically designed according to the needs of the specific cleaning equipment. The shape of the baffle 50 can be regular or irregular. There can be one baffle 50 or multiple baffles. When there are multiple baffles 50, the multiple baffles 50 can be arranged in sequence along the height direction, the multiple baffles 50 can also be arranged in sequence along the circumferential direction of the exhaust channel 40, and the multiple baffles 50 can be arranged at the same height.

[0099] In the above embodiment, based on the setting of the liquid collecting channel 30 along the height direction, the external liquid is transported upward along the height direction. After flowing out of the liquid outlet 302, the direction of the liquid changes by approximately 1° and then falls downward along the height direction. The sharp turn of the liquid is more conducive to the liquid falling from the liquid outlet 302 and entering the liquid collecting chamber 105, thereby increasing the inertia of the liquid entering the liquid collecting chamber 105 and reducing the probability of the liquid being carried away by the suction wind.

[0100] Based on the design of the first partition 2012e or the second partition 2012a, the path of the liquid falling from the liquid outlet 302 to the liquid collecting chamber 105 and the outlet path of the suction air are isolated, and then the liquid collecting channel 30 is made to fit in contact with the first partition 2012e or the second partition 2012a, so that the path of the liquid falling from the liquid outlet 302 to the liquid collecting chamber 105 is located on the side of the liquid collecting channel 30 that is not in contact with the first partition 2012e or the second partition 2012a, and by increasing the horizontal spacing, the path of the liquid falling from the liquid outlet 302 to the liquid collecting chamber 105 and the outlet path of the suction air are further isolated.

[0101] Based on the design of the liquid collecting channel 30 and the first partition 2012e, combined with the design of the first air inlet 4011, the air passage 80 and the second air inlet 4012, after the suction air is separated from the liquid, it enters the first air inlet 4011, and then turns to enter the air passage 80, and runs in the first direction toward the second air inlet 4012, so that it turns to enter the air extraction channel 40 again, and the liquid in part of the gas is further filtered out by two right-angle changes. Alternatively, based on the design of the liquid collecting channel 30 and the second partition 2012a, the air inlet 401 is designed on the lower side of the second partition 2012a, and after the suction air is separated from the liquid, it turns to enter the air inlet 401, and runs in the first direction toward the air inlet 401, so that it turns to enter the air extraction channel 40 again, and the liquid in part of the gas is further filtered out by two right-angle changes.

[0102] Based on the design of the liquid collecting channel 30, the first partition plate 2012e / the second partition plate 2012a and the air inlet 401, a plurality of baffles 50 are further designed to filter out the liquid in the gas through friction and blocking between the plurality of baffles 50, thereby further improving the efficiency and effect of gas-liquid separation.

[0103] In this way, through multiple designs, the suction air not only provides partial drive when the liquid falls into the liquid collecting chamber 105, but also helps the suction air to transform and separate from the liquid after providing the drive, and continue to transform and further separate from the liquid, and then use multiple baffles 50 to further filter the liquid. Through multiple system designs, the liquid collection and gas-liquid separation are completed, reducing or eliminating the probability of liquid damage to the motor.

[0104] The air outlet 402 may be disposed on the air outlet structure 403 , and the air outlet structure 403 may be disposed at the air outlet end of the exhaust channel 40 , for example, may be disposed at a local position of the top sealing portion 2011 described below facing the exhaust channel 40 .

[0116] In other embodiments, the water filter 202 can have a blocking effect on the liquid in the liquid collecting chamber 105 and the expansion chamber 107 described below when the liquid box structure is in a tilted / lying state, thereby preventing the liquid from being excessively agitated and entering the motor along with the gas.

[0117] In some embodiments, the cavity portion 2012 has a first partition 2012e, which extends in the height direction and isolates the liquid collecting channel 30 and the air extraction channel 40 on both sides thereof in the first direction, wherein the first direction is perpendicular to the height direction. The air inlet 401 includes a first air inlet 4011 and a second air inlet 4012, wherein the first air inlet 4011 is arranged on the side where the liquid collecting channel 30 is located, and the second air inlet 4012 is arranged on the side where the air extraction channel 40 is located, and the first air inlet 4011 and the second air inlet 4012 are respectively connected to the liquid collecting cavity 105. The liquid collecting cavity 105 has an air passage 80, which is located between the first air inlet 4011, the second air inlet 4012 and the highest liquid level line, and the suction air flows through the liquid outlet 302, the first air inlet 4011, the air passage 80, the second air inlet 4012 and the air extraction channel 40 in sequence. Moreover, the top side of the first partition 2012e is integrally connected to the top sealing portion 2011, the two sides of the first partition 2012e along the second direction are respectively integrally connected to the dividing chamber plate 2012c and sealed to the side wall of the box body 10, and the bottom side of the first partition 2012e is sealed to the water filter element 202, wherein the first direction, the second direction and the height direction are perpendicular to each other.

[0118] In some embodiments, the cavity portion 2012 has a second partition 2012a, the second partition 2012a is extended in the height direction, the second partition 2012a and the liquid collecting cavity 105 are spaced in the height direction to form an air inlet 401, part of the liquid collecting channel 30 and the air exhaust channel 40 are arranged on both sides of the second partition 2012a and the air inlet 401 along the first direction, and the first direction is perpendicular to the height direction.

[0120] The liquid collecting chamber 105 may be located at the bottom of the liquid tank structure, and part of the liquid collecting chamber 105 extends along the height direction of the liquid tank structure to form an expansion chamber 107, which is used to contain liquid when the liquid tank structure is in an inclined state. When the liquid tank structure is in an inclined state, the liquid in the liquid collecting chamber 105 will flow or agitate toward the expansion chamber 107, and the force generated by the agitation will be unloaded by the force release chamber 108 when the liquid reaches the expansion chamber 107, thereby weakening or eliminating the agitation phenomenon, and the liquid will not flow into the motor along with the gas due to agitation, thereby reducing the probability of damaging the motor and other components.

[0121] Furthermore, in some embodiments, the cavity portion 2012 of the support structure 20 has a cavity plate 2012c, the cavity plate 2012c contacts and cooperates with the first side wall 103 to form a partition cavity 106, and the cavity plate 2012c and the second side wall 104 are spaced and cooperated to form an expansion cavity 107. Based on this, from the direction of the expansion cavity 107 to the liquid collecting cavity 105, the distance between the cavity plate 2012c and the second side wall 104 gradually decreases.

[0122] In some embodiments, the portion of the chamber plate 2012c close to the water filter 202 is provided with a second liquid hole 2012f, and the second liquid hole 2012f allows liquid to enter the liquid collecting chamber 105 and / or the expansion chamber 107 from the partition chamber 106. The design of the chamber plate 2012c is conducive to forming the expansion chamber 107. The chamber plate 2012c is inclined, and the second liquid hole 2012f is arranged on the lower side, which is conducive to the liquid flowing out of the liquid outlet 302 flowing to the second liquid hole 2012f through the inclined chamber plate 2012c, and flowing into the liquid collecting chamber 105 and / or the expansion chamber 107 from the second liquid hole 2012f.

For the convenience of distinguishing descriptions, the liquid hole provided in the water filter 202 is the first liquid hole, and the liquid hole provided in the chamber dividing plate 2012c is the second liquid hole 2012f.

[0127] In some embodiments, a relief chamber 108 is provided at one end of the liquid tank structure away from the liquid collecting chamber 105. The relief chamber 108 is formed by the side wall of the expansion chamber 107 extending in a direction away from the liquid collecting chamber 105. For example, the relief chamber 108 can be formed by directly extending the side wall of the expansion chamber 107, or can be formed by the top seal portion as an extension of the expansion chamber. When the liquid tank structure is in an inclined state, the liquid in the liquid collecting chamber 105 will flow or agitate toward the expansion chamber 107. When the liquid reaches the relief chamber 108, the force generated by the agitation is unloaded by the relief chamber 108, and the agitation phenomenon is weakened or eliminated. The liquid will not flow into the motor along with the gas due to agitation, thereby reducing the probability of damaging the motor and other components.

[0128] In some embodiments, the liquid tank structure also includes a liquid level detection component 60, and a detection cavity 2012d is provided on at least one side of the cavity portion 2012 in the horizontal direction. The liquid level detection component 60 is configured in the detection cavity 2012d, and the detection end 604 of the liquid level detection component 60 is located on the highest liquid level line. By setting the liquid level detection component 60, liquid level detection can be achieved when the liquid tank structure is in an upright or inclined / lying state.

[0129] In some embodiments, the liquid tank structure includes two liquid level detection components 60, and detection cavities 2012d are respectively provided on both sides of the cavity portion 2012 in the horizontal direction. The two liquid level detection components 60 are respectively configured in the two detection cavities 2012d. The liquid is detected by the two liquid level detection components 60, and the detection points of the liquid are increased to improve the detection accuracy of the liquid level.

[0130] In some embodiments, the detection cavity 2012d extends a length along the height direction of the liquid tank structure, and the liquid level detection component 60 extends a length along the height direction, the length extending from the top seal portion 2011 to the water filter element 202, the upper end of the liquid level detection component 60 can be sealed and installed in cooperation with the top seal portion 2011, and the lower end of the liquid level detection component 60 can be flush with the lower edge of the water filter element 202, and the lower end is provided with a detection end 604.

[0131] The embodiment of the present application also provides a cleaning device including the above-mentioned liquid tank structure. The beneficial effects of the cleaning device provided by the embodiment of the present application compared with the prior art are consistent with the beneficial effects of the liquid tank structure provided by the present application compared with the prior art, and will not be repeated here.

[0132] Please refer to Figures 7 to 10 ,as well as Figures 15 to 17Another embodiment of the present application also provides another liquid tank structure, which has a liquid collecting chamber 105 and an expansion chamber 107. The liquid collecting chamber 105 is located at the bottom of the liquid tank structure, and a portion of the liquid collecting chamber 105 extends along the height direction of the liquid tank structure to form the expansion chamber 107. The expansion chamber 107 is used to contain liquid when the liquid tank structure is tilted. A pressure relief chamber 108 is provided at one end of the liquid tank structure away from the liquid collecting chamber 105. The pressure relief chamber 108 is formed by the side wall of the expansion chamber 107 extending in a direction away from the liquid collecting chamber 105.

[0133] A pressure relief chamber 108 is provided at one end of the liquid tank structure away from the liquid collecting chamber 105. The pressure relief chamber 108 is formed by the side wall of the expansion chamber 107 extending in a direction away from the liquid collecting chamber 105. When the liquid tank structure is in an inclined state, the liquid in the liquid collecting chamber 105 will flow or agitate toward the expansion chamber 107. When the liquid reaches the pressure relief chamber 108, the pressure relief chamber 108 unloads the force generated by the agitation, thereby weakening or eliminating the agitation phenomenon. The liquid will not flow into the motor along with the gas due to agitation, thereby reducing the probability of damaging the motor and other components.

[0134] In some embodiments, the pressure relief chamber 108 and the expansion chamber 107 are arranged sequentially along the height direction.

[0135] When the liquid tank structure is in a tilted state, the liquid in the liquid collecting chamber 105 flows or agitates along the height direction toward the expansion chamber 107. When the liquid reaches the pressure relief chamber 108 along the height direction, it continues to flow along the height direction, and then the force generated by the agitation is unloaded by the pressure relief chamber 108, so that the agitation phenomenon is weakened or eliminated, and the liquid will not flow into the motor along the gas due to the agitation, thereby reducing the probability of damaging the motor and other components.

[0136] In some embodiments, the pressure relief chamber 108 is disposed on the side of the expansion chamber 107 along the horizontal direction.

[0137] When the liquid tank structure is in a tilted state, the liquid in the liquid collecting chamber 105 flows or agitates along the height direction toward the expansion chamber 107. When the liquid reaches the pressure relief chamber 108 along the height direction, it changes direction and flows in the horizontal direction. Then, the force generated by the agitation is unloaded by the pressure relief chamber 108, and the agitation phenomenon is weakened or eliminated. The liquid will not flow into the motor along the gas due to the agitation, thereby reducing the probability of damaging the motor and other components.

[0138] In some embodiments, the side wall of the expansion cavity 107 includes a buffer zone 109, and the surface of the buffer zone 109 is arc-shaped. The buffer zone 109 is adjacent to the pressure relief cavity 108, and one end of the buffer zone 109 connected to the pressure relief cavity 108 is lower than the bottom surface of the pressure relief cavity 108 or is flush with the bottom surface of the pressure relief cavity 108. The side wall of the buffer zone 109 can be the first side wall 103 mentioned above.

[0139] By designing an arc-shaped buffer zone 109, the liquid can be buffered or relieved before reaching the relief chamber 108, and then further relieved through the relief chamber 108 to remove the force generated by the agitation to the greatest extent, thereby weakening or eliminating the agitation phenomenon, and the liquid will not flow into the motor along with the gas due to the agitation.

[0140] In some embodiments, the side wall of the expansion cavity 107 includes a buffer zone 109, and the surface of the buffer zone 109 is inclined; the buffer zone 109 is adjacent to the pressure relief cavity 108, and one end of the buffer zone 109 connected to the pressure relief cavity 108 is lower than the bottom surface of the pressure relief cavity 108 or is flush with the bottom surface of the pressure relief cavity 108, and the other end of the buffer zone 109 away from the pressure relief cavity 108 is lower than one end.

[0141] By designing an inclined buffer zone 109, the liquid can be buffered or relieved once before reaching the relief chamber 108, and then further relieved through the relief chamber 108 to remove the force generated by the agitation to the greatest extent, thereby weakening or eliminating the agitation phenomenon, and the liquid will not flow into the motor along with the gas due to the agitation.

[0142] In some embodiments, the liquid tank structure includes a tank body 10 and a support structure 20; the tank body 10 has a bottom wall 101 and an opening 102 arranged opposite to each other in the height direction. The support structure 20 is arranged in the tank body 10, and the top end of the support structure 20 in the height direction is sealed to the opening 102, and the bottom end is spaced from the bottom wall 101 to form a liquid collecting chamber 105, and a pressure relief chamber 108 is provided on one end of the support structure 20 away from the liquid collecting chamber 105.

[0143] The top of the support structure 20 in the height direction and the part used to close the opening 102 is arranged as the pressure relief chamber 108, so that the pressure relief chamber 108 can be located at the position farthest from the liquid collecting chamber 105, which not only extends the cavity volume of the expansion chamber 107 to the maximum extent, but also makes the pressure relief effect of the pressure relief chamber 108 reach the best. The liquid enters the expansion chamber 107 from the liquid collecting chamber 105 and then enters the pressure relief chamber 108. The path of the liquid is lengthened, and the agitation generated by the liquid is relieved in the order of the lengthened path.

[0144] In some embodiments, the support structure 20 includes a support body 201 and a water filter 202 which are sequentially arranged and connected along the height direction. The support body 201 includes a top seal portion 2011 and a cavity portion 2012, and the water filter 202 and the top seal portion 2011 are arranged at both ends of the cavity portion 2012 along the height direction. The top seal portion 2011 closes the opening 102, and the water filter 202 is spaced from the bottom wall 101 to form a liquid collecting chamber 105. The cavity portion 2012 has a cavity plate 2012c, and the cavity plate 2012c and the water filter 202 are spaced from the side wall of the box body 10 to form an expansion chamber 107, and the top seal portion 2011 is provided with a pressure relief chamber 10).

[0145] The pressure relief chamber 108 can be formed inside the edge of the top seal 2011, or the pressure relief chamber 108 can be provided at the sealing cooperation between the top seal 2011 and the opening 102. In some embodiments, the pressure relief chamber 108 can be formed inside the edge of the top seal 2011, and the outer edge of the pressure relief chamber 108 is sealed with the opening 102.

[0146] In some embodiments, the top seal portion 2011 and the cavity portion 2012 are integrally connected, and the pressure relief chamber 108 is provided in an area on the top seal portion 2011 located beside the cavity portion 2012. In some embodiments, the pressure relief chamber 108 extends to a certain size along the horizontal extension direction of the side wall of the cavity portion 2012. In this way, the pressure relief chamber 108 can be arranged according to the structure of the cavity portion 2012, the volume of the pressure relief chamber 108 can be expanded to the greatest extent, and the pressure relief chamber 108 can be extended along the extension direction of the side wall of the cavity portion 2012, further expanding the volume of the pressure relief chamber 108 and improving its pressure relief effect on the liquid.

[0147] An embodiment of the present application also provides another cleaning device including another liquid tank structure provided by another embodiment mentioned above. The beneficial effects of the other cleaning device provided by the embodiment of the present application compared with the prior art are consistent with the beneficial effects of the other liquid tank structure provided by the embodiment of the present application compared with the prior art, and will not be repeated here.

[0148] Please refer to Figures 18 to 20 ,as well as Figure 32 to Figure 34 As shown, the liquid level detection member 60 provided in the embodiment of the present application has a detection end 604, and the detection end 604 is provided with a first detection position 6071 and a second detection position 6072. The first detection position 6071 is provided at the end of the detection end 604, and the first detection position 6071 is provided with a first liquid level sensor element 605, and the first liquid level sensor element 605 is used to detect the liquid level when the liquid tank structure is in the first use state. The second detection position 6072 is provided on the side of the detection end 604, and the second detection position 6072 is provided with a second liquid level sensor element 606, and the second liquid level sensor element 606 is used to detect the liquid level when the liquid tank structure is in the second use state.

[0149] With such a design, two detection positions at different locations can be set on the same liquid level detection member 60, and two liquid level sensor elements respectively located at the end and the side can be installed to realize liquid level detection in a first use state and liquid level detection in a first use state, such as liquid level detection in an upright state and a lying / inclined state, without occupying space inside the equipment, and also reducing material costs and installation costs.

[0150] Among them, the end refers to the area on the detection end 604 that is infinitely close to its end face, which can be the end face itself or the area infinitely close to the end face, and the side refers to the area on the detection end that is far away from the end face of the detection end, and has a certain size or distance between it and the end face.

[0157] In some embodiments, the first detection position 6071 is one or more, and / or the second detection position 6072 is one or more, and the number of the first detection position 6071 and the second detection position 6072 can be adaptively set according to specific detection requirements.

[0158] It should be noted that, except for the different side surfaces, the number, type and arrangement of the first detection position 6071 and the second detection position 6072 can be the same or different. The number, type and arrangement of the first liquid level sensor element 605 and the second liquid level sensor element 606 can be the same or different.

[0159] Among them, in the above-mentioned liquid tank structure provided with the first partition plate 2012e, it is applicable as follows Figure 32 to Figure 34 The liquid level detection member shown in the figure has a short distance between the first detection position and the second detection position in the height direction. Figures 18 to 20 In the liquid level detection member shown, the distance between the first detection position and the second detection position in the height direction is relatively long.

[0160] The embodiment of the present application also provides a liquid tank structure including the above-mentioned liquid level detection component 60.

[0161] The liquid tank structure has a liquid collecting chamber 105 and an expansion chamber 107. The liquid collecting chamber 105 is located at the bottom of the liquid tank structure. Part of the liquid collecting chamber 105 extends along the height direction of the liquid tank structure to form the expansion chamber 107. The expansion chamber 107 is used for the liquid tank structure to contain liquid when it is tilted. The liquid tank structure includes the above-mentioned liquid level detection component 60. The detection end 604 of the liquid level detection component 60 is arranged at the connection point between the liquid collecting chamber 105 and the expansion chamber 107. The first liquid level sensor element 605 and the second liquid level sensor element 606 are respectively arranged toward the expansion chamber 107 and the liquid collecting chamber 105.

[0162] In some embodiments, the liquid tank structure includes two liquid level detection members 60, and detection cavities 2012d are respectively provided on both sides of the expansion cavity 107 in the horizontal direction. The two liquid level detection members 60 are respectively arranged in the two detection cavities 2012d, and the detection end 604 is exposed.

[0164] Please refer to the figure Figures 10 to 14 As shown, the embodiment of the present application also provides a cleaning device including the above-mentioned liquid tank structure with a liquid level detection component 60. The beneficial effects of the cleaning device provided by the embodiment of the present application compared with the prior art are consistent with the beneficial effects of the liquid tank structure with a liquid level detection component 60 provided by the present application compared with the prior art, and will not be repeated here.

[0165] The water filter 202 provided in the embodiment of the present application includes a main baffle 2021 and an auxiliary baffle 2022. The main baffle 2021 has a first side surface 2021a and a second side surface 2021b that are arranged in a manner opposite to each other, and the auxiliary baffle 2022 is convexly arranged on the second side surface 2021b, and the auxiliary baffle 2022 separates the second side surface 2021b into a first area 2021d and a second area 2021c. The main baffle 2021 is configured to allow liquid to pass through the second area 2021c from the side where the first side surface 2021a is located and reach the side where the second side surface 2021b is located; and when the main baffle 2021 is at an angle with the horizontal plane and the liquid level is located in the second area 2021c, the auxiliary baffle 2022 is used to prevent the liquid from reaching the first area 2021d from the second area 2021c.

[0166] The water filter 202 is applied to the liquid tank structure, and the liquid can pass through the second area 2021c from the first side 2021a to the second side 2021b. When the liquid tank structure is in an inclined state, that is, when the main baffle 2021 is at an angle with the horizontal plane and the liquid level is in the second area 2021c, the auxiliary baffle 2022 is used to prevent the liquid from reaching the first area 2021d from the second area 2021c. For example, when the liquid tank structure collects sewage and the liquid generates a large water agitation phenomenon, the sewage in the agitated state is not easily agitated to the first side 2021a, that is, the side where the exhaust channel 40 is located, and the liquid does not flow into the motor along with the gas, thereby reducing the probability of damaging the motor and other components.

[0167] In some embodiments, the first region 2021d is provided with a plurality of via holes 2023 penetrating the thickness of the main baffle plate 2021 , the plurality of via holes 2023 are sequentially spaced apart along the extension direction of the auxiliary baffle wall 2022 , and the plurality of via holes 2023 are spaced apart from the auxiliary baffle wall 2022 .

[0168] By setting a plurality of through holes 2023, when the liquid tank is in a tilted state, the suction air can form an air suction path from the partition chamber 106, the second liquid hole 2012f, the liquid collecting chamber 105, and the through holes 2023, so as to increase the driving force of the suction air on the liquid to enter the liquid collecting chamber 105, and the through holes 2023 can filter the liquid contained in the suction air.

[0169] In some embodiments, an annular retaining wall 2024 is protruded from the first region 2021 d , the through hole 2023 is located on the inner side of the annular retaining wall 2024 , and the annular retaining wall 2024 is spaced apart from the auxiliary retaining wall 2022 .

[0170] When the liquid tank structure is in a tilted / lying state, the liquid swings onto the auxiliary baffle 2022 of the water filter 202, and the generated water splashes are blocked by the auxiliary baffle 2022, and then fall back into the water collection chamber. By setting the annular baffle 2024, the annular baffle 2024 and the auxiliary baffle 2022 are spaced apart to form another water retaining area. When the water swings to the water retaining area, it can still be blocked by the annular baffle 2024 and flow back into the inside of the liquid collection chamber 105.

[0171] In some embodiments, two connecting walls 2025 are protrudingly provided on the first region 2021 d , and the two extended ends of the auxiliary retaining wall 2022 are connected to the annular retaining wall 2024 through the two connecting walls 2025 .

[0172] The auxiliary retaining wall 2022 and the annular retaining wall 2024 are connected at the same side ends thereof by two connecting walls 2025, so that another water retaining area mentioned above can be arranged in a circumferentially closed manner, thereby further improving the barrier effect on the liquid.

[0173] In some embodiments, there are multiple annular retaining walls 2024 , which are sequentially connected along the extension direction of the auxiliary retaining wall 2022 , and at least one through hole 2023 is disposed on the inner side of each annular retaining wall 2024 .

[0174] Combined with the setting of the annular retaining wall 2024 and the through hole 2023, the annular retaining wall 2024 can block the liquid. Even if the liquid passes over the annular retaining wall 2024, the through hole 2023 can filter the liquid, further preventing the liquid from entering the first side 2021a from the side where the second side 2021b is located.

[0175] In some embodiments, a secondary barrier wall is disposed on the first region 2021 d , the secondary barrier wall is spaced apart from the auxiliary barrier wall 2022 , and a plurality of vias 2023 are disposed on a side of the secondary barrier wall away from the auxiliary barrier wall 2022 .

[0176] When the liquid tank structure is in a tilted / lying state, the liquid swings onto the auxiliary baffle 2022 of the water filter 202, and the generated water splashes are blocked by the auxiliary baffle 2022, and then fall back into the water collection chamber. By setting the secondary baffle, the secondary baffle and the auxiliary baffle 2022 are spaced apart to form another water retaining area. When the water swings to the water retaining area, it can still be blocked by the annular baffle 2024 and flow back into the inside of the liquid collection chamber 105.

[0177] Combined with the secondary baffle wall and the via 2023, the secondary baffle wall can block the liquid. Even if the liquid passes over the secondary baffle wall, the via 2023 can filter the liquid, further preventing the liquid from entering the first side 2021a from the second side 2021b.

[0178] The secondary barrier wall may be a strip barrier wall parallel to the auxiliary barrier wall 2022 , and the through hole 2023 is arranged on a side of the secondary barrier wall away from the auxiliary barrier wall 2022 .

[0179] In some embodiments, two limiting retaining walls 2026 are protruded from the second region 2021c, and the two limiting retaining walls 2026 are respectively connected to the auxiliary retaining wall 2022 at an angle, and the two limiting retaining walls 2026 and the auxiliary retaining wall 2022 jointly define the second region 2021c.

[0180] The second area 2021c is defined by the two limiting walls 2026 and the auxiliary wall 2022, so that the second area 2021c is called a U-shaped structure open toward the expansion cavity 107, which is more conducive to blocking the liquid in three directions and improves the blocking effect.

[0181] In some embodiments, a fitting hole 2027 is opened at the central position of the second area 2021c, and the fitting hole 2027 is used to seal and fit the liquid collection channel 30, and the liquid collection channel 30 is used to transport external liquid to the side where the first side surface 2021a is located.

[0182] By installing the liquid collecting channel 30 through the fitting hole 2027 on the water filter 202, it is possible to improve the integration of the water filter 202 and the liquid collecting channel 30, that is, to improve the integration of the internal structure of the box body 10, while facilitating the entry of external liquid along the height direction, and facilitating the liquid to enter the liquid collecting chamber 105 by inertia after turning, thereby making it more conducive to separation from the gas.

[0183] Among them, in Figure 21 to Figure 31 In the provided embodiment, in the above-mentioned liquid box structure provided with the first partition plate 2012e, among the multiple through holes 2023, several through holes 2023 are arranged on the side where the liquid collecting channel 30 is located, and these several through holes 2023 can be used as the first air inlet 4011, and another several through holes 2023 are arranged on the side where the exhaust channel 40 is located, and these another several through holes 2023 can be used as the second air inlet 4012.

[0184] Among them, in Figures 1 to 17 In the provided embodiment, in the above-mentioned liquid box structure provided with the second partition plate 2012a, the design of the plurality of through holes 2023 can be cancelled, or the design of the plurality of through holes 2023 can be retained. When the design of the plurality of through holes 2023 is retained, the plurality of through holes 2023 are used as filtering holes that can filter the liquid. Of course, in this embodiment, it is not excluded that a small amount of wind force will flow through the plurality of through holes 2023, but the vast majority of the suction wind still flows through the air inlet 401 formed by the interval between the second partition plate 2012a and the water filter 202.

[0185] The embodiment of the present application also provides a liquid box structure having the above-mentioned water filter 202, the liquid box structure having a liquid collecting chamber 105 and an expansion chamber 107 connected to the liquid collecting chamber 105. The liquid box structure includes the above-mentioned water filter 202, the side where the second side 2021b of the water filter 202 is located is the liquid collecting chamber 105, and the expansion chamber 107 is located beside the water filter 202 and extends from the second side 2021b to the direction of the first side 2021a.

[0186] In some embodiments, the liquid box structure further includes a liquid collecting channel 30, and the second area 2021c is provided with a fitting hole 2027, and the liquid collecting channel 30 is fitted in the fitting hole 2027. Part of the liquid collecting channel 30 is located on the side where the first side 2021a is located and has a liquid outlet 302, and the liquid from the liquid outlet 302 enters from the side where the first side 2021a is located to the side where the second side 2021b is located and reaches the liquid collecting chamber 105; another part of the liquid collecting channel 30 is located on the side where the second side 2021b is located and has a liquid inlet 301.

[0187] The liquid collecting channel 30 is arranged along the height direction, and the external liquid is transported upward along the height direction. After flowing out of the liquid outlet 302, the direction of the liquid changes by approximately 1° and then falls downward along the height direction. The sharp turn of the liquid is more conducive to the liquid falling from the liquid outlet 302 and entering the liquid collecting chamber 105, thereby increasing the inertia of the liquid entering the liquid collecting chamber 105, reducing the probability of the liquid being carried away by the suction wind, further reducing the liquid content in the suction wind, and reducing the probability of the motor being damaged.

[0188] In some embodiments, the liquid box structure further includes an air suction channel 40, which has an air inlet 401 and an air outlet 402 that are interconnected, and the air inlet 401 is arranged between the liquid outlet 302 and the liquid collecting chamber 105 along the height direction. The air suction channel 40 provides suction wind directed from the air inlet 401 to the air outlet 402, and the suction wind is used to suck liquid from the liquid inlet 301 to the liquid outlet 302, and when the liquid falls from the liquid outlet 302 to the liquid collecting chamber 105, it is separated from the liquid and enters the air inlet 401.

[0189] The height of the liquid outlet 302 of the liquid collecting channel 30 is higher than the height of the liquid inlet 301. Through the wind force applied by the suction wind, the external liquid can enter the liquid collecting channel 30 from the liquid inlet 301 and be transported upward to the liquid outlet 302 along the height direction. Through the wind force applied by the suction wind and / or the dead weight of the liquid, the liquid enters the liquid collecting chamber 105 downward from the liquid outlet 302 along the height direction. Since the air inlet 401 of the air suction channel 40 is arranged between the liquid outlet 302 and the highest liquid level line along the height direction, when the liquid falls from the liquid outlet 302 to the liquid collecting chamber 105, the suction wind separates from the liquid and enters the air inlet 401. In this process, the suction direction of the suction wind changes relative to the direction in which the liquid enters the liquid collecting chamber 105. The liquid falls into the liquid collecting chamber 105 due to the inertial force of its own weight, and is not easily brought into the air suction channel 40 by the suction wind, thereby avoiding the problem of liquid entering the motor and causing electrode damage.

[0190] In some embodiments, the first area 2021d is provided with a plurality of through holes 2023 that penetrate the thickness of the main baffle plate 2021, the plurality of through holes 2023 are sequentially spaced along the extension direction of the auxiliary baffle wall 2022, and the plurality of through holes 2023 are spaced apart from the auxiliary baffle wall 2022; the expansion cavity 107 is located on the side of the water filter 202 that is away from the plurality of through holes 2023.

[0191] When the liquid tank structure is in a tilted / lying state, the expansion chamber 107 is located below the auxiliary baffle 2022, and the auxiliary baffle 2022 blocks the liquid from reaching the first area 2021d from the second area 2021c. For example, when sewage is collected in the expansion chamber 107 and the liquid collecting chamber 105, and the liquid generates a large water agitation phenomenon therein, the sewage in the agitated state is not easily agitated to the first side 2021a, that is, the side where the exhaust channel 40 is located, and the liquid does not flow into the motor with the gas, thereby reducing the probability of damaging the motor and other components. Even if the liquid passes over the auxiliary baffle 2022, the liquid can be filtered through the through hole 2023, further preventing the liquid from entering the first side 2021a from the side where the second side 2021b is located in the reverse direction.

[0192] The beneficial effects of the liquid box structure with the water filter element 202 provided in the embodiment of the present application compared with the prior art are consistent with the beneficial effects of the water filter element 202 provided in the embodiment of the present application compared with the prior art, and will not be repeated here.

[0193] The embodiment of the present application also provides a cleaning device, which includes the above liquid tank structure with a water filter 202. The beneficial effects of the cleaning device provided by the embodiment of the present application compared with the prior art are consistent with the beneficial effects of the water filter 202 and the liquid tank structure with the water filter 202 provided by the embodiment of the present application compared with the prior art, and will not be repeated here.

[0194] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
