[0093] Embodiments of the present disclosure provide a cleaning device, such as Figure 1 shown, the cleaning device 10 is, for example, a floor washer. It should be noted that the present disclosure elaborates on the cleaning device through the floor washer, which is only a preferred embodiment of the present disclosure and does not limit the protection scope of the cleaning device of the present disclosure. For example, the cleaning device of the present disclosure can be a handheld floor washer with a handlebar and manually operated by a user, or it can also be a self-propelled floor scrubbing robot with driving wheels. The floor scrubbing robot can control the driving wheels to travel according to the program stored in itself and control the cleaning roller to clean the floor. For another example, the cleaning device of the present disclosure can also be other cleaning devices such as a mopping machine, a sweeping machine, an electric mop, etc.

[0094] Below, the present disclosure will be described in detail taking the cleaning device 10 as a handheld floor washer as an example.

[0095] Specifically, as Figure 1 shown, the handheld floor washer includes a body 100 and a cleaning base 200. The body 100 includes opposite first and second ends along its length direction, and the cleaning base 200 is connected to the second end of the body 100; a handle assembly 140 is provided on the body 100, and the handle assembly 140 is connected to the first end of the body 100 away from the cleaning base 200 for the user to operate and hold. By holding the handle assembly 140, the user can control the cleaning base 200 to move on the surface to be cleaned, so as to achieve the purpose of cleaning the surface to be cleaned.

[0096] Among them, the cleaning base 200 is hinged to the body 100, such as pivotally connected, ball-jointed, etc.; when the user holds the handle assembly 140 to control the cleaning base 200 to move on the surface to be cleaned, by making the cleaning base 200 hinged to the body 100, the relative angle between the body 100 and the cleaning base 200 can be adjusted, thereby changing the operation angle and flexibly adjusting the cleaning posture for convenient cleaning operation.

[0097] Among them, as Figures 2 to 4As shown, a water tank 120 and a sewage tank 130 are provided on the main body 110 of the machine body 100. When the cleaning head on the cleaning base 200 of the floor washer is mopping the floor, the cleaning liquid is provided to the cleaning head through the cooperation of the water tank 120 and the liquid supply component to mop and wash the floor. The sewage tank 130 is configured to hold sewage, so that the sewage generated when mopping the floor and the collected sundries are pumped into the sewage tank 130 through the sewage suction channel by means of a negative pressure device. Therefore, it is necessary to accurately judge whether the sewage in the sewage tank 130 is full.

[0098] In this regard, an embodiment of the present disclosure provides a sewage tank 130, as Figures 5 to 7 shown, the sewage tank 130 includes a tank body 131 and a liquid level monitoring component 138. The tank body 131 forms a containing space 1311; an open end of the containing space 1311 is provided at the top of the tank body 131 along the height direction Z, and a sewage inlet 1312 is provided at the bottom of the tank body 131; the liquid level monitoring component 138 includes a first monitoring point 13851 and a second monitoring point 1352 located in the containing space 1311. In the height direction Z of the tank body 131, the second monitoring point 1352 is located above the first monitoring point 13851.

[0099] When the hand-held floor washer is at the normal working angle, the included angle between the machine body 100 of the hand-held floor washer and the ground is about 45°, as Figure 6 shown. At this time, the sewage tank 130 is also in the normal state of about 45°; when the hand-held floor washer is at the lying flat working angle, the machine body 100 of the hand-held floor washer is basically parallel to the ground, as Figure 7 shown. At this time, the sewage tank 130 is also in the lying flat state basically parallel to the ground; since the liquid level of the sewage in the sewage tank 130 will change when the sewage tank 130 is in the normal state of about 45° and the lying flat state basically parallel to the ground, if the liquid level of the sewage in the sewage tank 130 in the normal state and the lying flat state cannot be accurately monitored, it will cause the situation that the sewage in the sewage tank 130 is full but not detected in time, resulting in the hand-held floor washer being unable to continue to work normally, seriously affecting the user experience.

[0100] The sewage tank 130 provided by the present disclosure can monitor the sewage level extracted from the tank body 131 when the sewage tank 130 is in a lying state through the first monitoring point 13851 at a lower position. When the sewage level reaches the height of the first monitoring point 13851, the sewage continuously submerges the first monitoring point 13851, and it can be determined that the extracted sewage in the sewage tank 130 is full. At this time, the second monitoring point 1352 at a higher position is not submerged by the sewage; through the second monitoring point 1352 at a higher position, the sewage level extracted from the tank body 131 when the sewage tank 130 is in a lying state can be monitored; when the sewage level reaches the height of the second monitoring point 1352, the sewage continuously submerges the second monitoring point 1352, and at this time, it can be determined that the extracted sewage in the sewage tank 130 is full; through the first monitoring point 13851 and the second monitoring point 1352 at different heights, an accurate judgment can be made on whether the sewage in the sewage tank 130 has been fully pumped in the normal state and the lying state, thus avoiding the phenomenon that the sewage in the sewage tank 130 cannot be detected in time after being fully pumped. Therefore, it also avoids excessive water vapor entering the negative pressure device due to failure to stop the machine in time after the sewage is fully pumped, improves the safety of the negative pressure device, and increases the service life of the negative pressure device.

[0101] In some embodiments, as Figure 5 shown, the liquid level monitoring component 138 includes: a first monitoring rod 1381 and a second monitoring rod 1382. The first monitoring rod 1381 and the second monitoring rod 1382 are located in the accommodation space 1311 and extend along the height direction Z; the first monitoring point 13851 and the second monitoring point 1352 are formed on both the first monitoring rod 1381 and the second monitoring rod 1382. One of the first monitoring rod 1381 and the second monitoring rod 1382 is the positive electrode, and the other is the negative electrode.

[0102] When the sewage tank 130 is at the normal working angle and the sewage level reaches the height of the first monitoring point 13851, when the sewage continuously submerges the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382, the first monitoring points 13851 on the positive electrode monitoring rod and the negative electrode monitoring rod are electrically connected through the sewage to form a circuit, and it can be determined that the extracted sewage in the sewage tank 130 is full. At this time, the second monitoring point 1352 at a higher position on the first monitoring rod 1381 and the second monitoring rod 1382 is not submerged by the sewage; when the sewage tank 130 is at the lying working angle and the sewage level reaches the height of the second monitoring point 1352, the sewage continuously submerges the first monitoring point and the second monitoring point 1352, and the first monitoring points 13851 and the second monitoring points 1352 on the positive electrode monitoring rod and the negative electrode monitoring rod are simultaneously electrically connected through the sewage to form two parallel circuits, and at this time, it can be determined that the extracted sewage in the sewage tank 130 is full.

[0103] Among them, a controller may be provided on the sewage tank 130 or other component structures of the cleaning device 10 to judge the electrical signal between the first monitoring rod 1381 and the second monitoring rod 1382. For example, when a loop is formed through sewage conduction between the first monitoring points 13851 on the monitoring rod of the positive electrode and the monitoring rod of the negative electrode, the height of the liquid level can be judged by setting a fixed voltage and judging the magnitude of the current; alternatively, the height of the liquid level can be judged by judging the resistance between the monitoring rod of the positive electrode and the monitoring rod of the negative electrode. When the first monitoring points 13851 and the second monitoring points 1352 on the monitoring rod of the positive electrode and the monitoring rod of the negative electrode are simultaneously connected through sewage to form two parallel loops, at this time, the height of the liquid level in the sewage tank 130 in the lying state can be judged by judging the magnitude of the current; alternatively, the height of the liquid level can be judged by judging the resistance between the monitoring rod of the positive electrode and the monitoring rod of the negative electrode.

[0104] Since the sewage in the sewage tank 130 shakes during the movement process, when the liquid level rises during the shaking of the sewage, the monitoring points may be briefly submerged, which may cause false alarms of the liquid level. In this regard, when the monitoring points on the monitoring rod of the positive electrode and the monitoring rod of the negative electrode are connected, the controller obtains the change of the electrical signal. At this time, a preset delay time can be set through the controller; if the duration after the change of the electrical signal is greater than the preset delay time, it is judged that the liquid level has reached the monitoring point; if the duration after the change of the electrical signal is less than or equal to the preset delay time, it is judged that the liquid level has not reached the monitoring point, so as to avoid false alarms of the liquid level and improve the accuracy of liquid level monitoring.

[0105] Among them, the preset delay time may be greater than three seconds, such as four seconds, five seconds, etc., and the present disclosure does not limit this. By controlling the preset delay time, that is, the conduction time between the monitoring points, the amount of water at full water alarm can be further controlled, and the adjustment of the normal full water and lying flat full water alarm capacities can be realized.

[0106] Among them, the inclination angle of the body 100 can be monitored through the IMU (inertial measurement) on the body 100, and different angles can correspond to different preset delay times, so as to accurately control the alarm capacity when the box body 131 is full of water at different angles of the body 100. For example, when the inclination angle between the body 100 and the ground is smaller, the sewage is more likely to submerge the second monitoring point 1352, and the preset delay time can be relatively increased.

[0107] In some embodiments, in the height direction Z of the box body 131, the heights of the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382 are consistent, and the sewage can simultaneously immerse the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382; or, the heights of the second monitoring point 1352 on the first monitoring rod 1381 and the second monitoring rod 1382 are consistent, and the sewage can simultaneously immerse the first monitoring point 1352 on the first monitoring rod 1381 and the second monitoring rod 1382; or, the heights of the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382 are consistent, and the heights of the second monitoring point 1352 on the first monitoring rod 1381 and the second monitoring rod 1382 are also consistent; the sewage can simultaneously immerse the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382, as well as the second monitoring point 1352 on the first monitoring rod 1381 and the second monitoring rod 1382.

[0108] Of course, the height of the first monitoring point 13851 on the first monitoring rod 1381 and the second monitoring rod 1382 may have a height difference, and the height of the second monitoring point 1352 on the first monitoring rod 1381 and the second monitoring rod 1382 may also have a height difference, and the present disclosure does not limit this.

[0109] In some embodiments, as Figures 5 to 7 As shown, the upper first monitoring point 13851 of the first monitoring rod 1381 is located at the end of the first monitoring rod 1381; or, the first monitoring point 13851 on the second monitoring rod 1382 is located at the end of the second monitoring rod 1382; or, the upper first monitoring point 13851 of the first monitoring rod 1381 is located at the end of the first monitoring rod 1381, and the first monitoring point 13851 on the second monitoring rod 1382 is also located at the end of the second monitoring rod 1382, which can relatively shorten the length of the monitoring rod, ensure the reliability of the monitoring rod, and avoid the monitoring rod occupying too much space in the box 131.

[0110] Of course, the first monitoring point 13851 on the first monitoring rod 1381 may not be located at the end of the first monitoring rod 1381, and the first monitoring point 13851 on the second monitoring rod 1382 may not be located at the end of the second monitoring rod 1382. This disclosure does not impose any restrictions on this.

[0111] In some embodiments, as Figure 8 and Figure 9 As shown, the first monitoring rod 1381 and the second monitoring rod 1382 both include a conductive column 13861 and an insulating layer 13862 covering the conductive column 13861 , and the conductive column 13861 is exposed through the insulating layer 13862 at the first monitoring point 13851 and the second monitoring point 1352 .

[0112] Among them, the insulating layer 13862 can be a plastic material layer formed on the surface of the metal conductive column 13861 through an injection molding process, and the formed monitoring rod has high corrosion resistance and stability.

[0113] In some embodiments, the sewage tank 130 further includes: a separation component 132, at least part of the separation component 132 is located in the accommodation space 1311, the separation component 132 forms an air duct in the accommodation space 1311, the inlet of the air duct is communicated with the sewage inlet 1312, the outlet of the air duct is used to connect a negative pressure device, and the middle part of the air duct is communicated with the accommodation space 1311.

[0114] Among them, the liquid level monitoring component 138 is connected to the separation component 132, that is, the liquid level monitoring component 138 can be taken out of the box body 131 through the separation component 132, so as to avoid affecting the dumping of sewage and sundries.

[0115] In some embodiments, the liquid level monitoring component includes: a first liquid level sensor and a second liquid level sensor, the first liquid level sensor forms a first monitoring point, and the second liquid level sensor forms a second monitoring point. By setting two liquid level sensors with different heights, the height of the liquid surface can be directly monitored.

[0116] Among them, the first liquid level sensor and the second liquid level sensor can be coaxially arranged or offset in the height direction.

[0117] In some embodiments, as Figure 10 shown, the separation component 132 forms a first air duct 13241, a second air duct 13242 and a third air duct 13243 in the accommodation space 1311. The inlet of the first air duct 13241 is communicated with the sewage inlet 1312, the outlet of the first air duct 13241 is located on the side close to the top and is communicated with the inlet of the second air duct 13242, the outlet of the second air duct 13242 is located on the side close to the bottom and is communicated with the accommodation space 1311; the inlet of the third air duct 13243 is located on the side close to the bottom and is communicated with the accommodation 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 device 10, and the negative pressure device is, for example, a fan.

[0118] The separation component 132 forms a first air duct 13241, a second air duct 13242 and a third air duct 13243 in the storage 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. Since the outlet of the first air duct 13241 is located on the side near the top and is connected to the inlet of the second air duct 13242, the outlet of the second air duct 13242 is located on the side near the bottom and is connected to the storage space 1311. 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, thereby reducing the amount of water vapor entering the fan and improving the safety and service life of the fan.

[0119] In some embodiments, as Figures 10 to 13 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.

[0120] 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.

[0121] In some embodiments, as Figure 11 As shown, the liquid level monitoring assembly 138 is connected to the separation bracket 1321, that is, the liquid level monitoring assembly 138 can be taken out from the box 131 through the separation bracket 1321 to avoid affecting the dumping of sewage and debris.

[0122] Among them, a plurality of mounting holes are provided on the separation bracket 1321 , and the first monitoring rod 1381 and the second monitoring rod 1382 are respectively inserted into the corresponding mounting holes, so as to facilitate the assembly of the first monitoring rod 1381 and the second monitoring rod 1382 .

[0123] In some embodiments, as Figure 11 shown, the liquid level monitoring component 138 further includes a first contact electrode 1383 and a second contact electrode 1384, and the first contact electrode 1383 and the second contact electrode 1384 are disposed on the mounting portion 13211; the first contact electrode 1383 is connected to the first monitoring rod 1381, and the second contact electrode 1384 is connected to the second monitoring rod 1382. By providing the first contact electrode 1383 and the second contact electrode 1384, the first monitoring rod 1381 is connected to the controller through the first contact electrode 1383, and the second monitoring rod 1382 is connected to the controller through the second contact electrode 1384, so as to realize the monitoring of the change of the electrical signal by the controller.

[0124] Wherein, the first contact electrode 1383 and the first monitoring rod 1381 may be of an integral structure, the second contact electrode 1384 and the second monitoring rod 1382 may be of an integral structure, and the first contact electrode 1383 and the second contact electrode 1384 may be fixedly assembled on the mounting portion 13211 by a snap connection. An installation groove communicating with the installation hole may be provided on the mounting portion 13211. When the monitoring rod is assembled into the installation hole, the contact electrode is assembled into the installation groove. Of course, the first contact electrode 1383 and the first monitoring rod 1381 may be of a split structure, the second contact electrode 1384 and the second monitoring rod 1382 may be of a split structure, and the contact electrode and the monitoring rod may be connected by means of plugging, abutting, etc., and the present disclosure does not limit this.

[0125] In some embodiments, as Figures 10 to 13 shown, the air duct portion 13212 includes an air duct 132120, and the air duct 132120 forms a second air duct 13242. By forming the second air duct 13242 through the air duct 132120, the volume occupied by the second air duct 13242 in the accommodation space 1311 is reduced, and at the same time, the drainage effect on the sewage can be improved.

[0126] Wherein, as Figures 10 to 13 shown, the air duct 132120 includes a duct main body 132121 and an elbow 132122, the outlet of the elbow 132122 is hermetically connected to the duct main body 132121, and the inlet of the elbow 132122 is communicated with the outlet of the first air duct 13241. The elbow 132122 and the duct main body 132121 form the second air duct 13242. The second air duct 13242 forms a first 90° turn at the elbow 132122 and a second 90° turn at the position where the elbow 132122 is connected to the duct main body 132121, so that the sewage entering the first air duct 13241 realizes a 180° turn through the second air duct 13242.

[0127] Among them, the air duct main body 132121 and the elbow 132122 can be detachably connected by means of threaded connection, snap connection, etc. A first sealing ring 132123 can also be provided between the positions where the air duct main body 132121 and the elbow 132122 are connected to improve the sealing performance of the connection between the air duct main body 132121 and the elbow 132122, and prevent sewage from leaking out at the connection position or air leakage at the connection position, resulting in a reduction in the air-water separation effect. Of course, the air duct main body 132121 and the elbow 132122 can also be fixedly connected in a non-detachable manner by means of bonding, welding, etc., or the air duct main body 132121 and the elbow 132122 can also be an integrally formed structure, and the present disclosure does not limit this.

[0128] Among them, on both sides of the air duct 132120 of the separation bracket 1321 in the thickness direction Y of the box body 131, there are formed extension parts 132125. The extension parts 132125 on both sides are in sealing contact with the side walls 1315 of the box body 131, so as to enclose and form a third air duct 13243 through the air duct 132120, the extension parts 132125 on both sides and the side walls 1315 of the box body 131. Rubber sealing parts can be provided between the extension parts 132125 on both sides and the side walls 1315 of the box body 131 to improve the sealing effect between the extension parts 132125 and the side walls 1315.

[0129] Among them, in the thickness direction Y of the box body 131, the first monitoring rod 1381 and the second monitoring rod 1382 are located on both sides of the air duct 132120; in the width direction X of the box body 131, the first monitoring rod 1381 and the second monitoring rod 1382 can be located at the middle position of the box body 131 to improve the accuracy of liquid level monitoring.

[0130] In some embodiments, as Figure 10 shown, the air duct part 13212 further includes a sewage inlet pipe 1322. The sewage inlet pipe 1322 forms a first air duct 13241. The inlet of the sewage inlet pipe 1322 is connected to the sewage inlet 1312 on the box body 131, and the inlet of the air duct 132120 is hermetically inserted into the outlet of the sewage inlet pipe 1322. By forming the first air duct 13241 through the sewage inlet pipe 1322 and cooperating with the second air duct 13242 of the air duct part 13212 on the separation bracket 1321, a 180° turn of the sewage is realized, so that the sewage moves downward and falls to the bottom of the sewage tank 130; setting the sewage inlet pipe 1322 and the separation bracket 1321 in a hermetically inserted connection form facilitates removing the separation bracket 1321 from the sewage tank 130 to pour out the sewage in the sewage tank 130 from the open end 1313.

[0131] Among them, when the air duct 132120 includes an air duct main body 132121 and an elbow 132122, the elbow 132122 and the water inlet pipe can be connected together by plugging. By providing the elbow 132122, it is convenient to adjust the plugging direction between the elbow 132122 and the water inlet pipe, so that the plugging direction between the elbow 132122 and the water inlet pipe is along the height direction Z of the box body 131, thus facilitating the removal of the separation bracket 1321 from the box body 131.

[0132] Among them, as Figure 10 shown, when the elbow 132122 is plugged with 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 is connected to the water inlet pipe as an active part when the elbow 132122 is plugged with the water inlet pipe, by designing the inlet of the elbow 132122 to be larger, it is convenient for the elbow 132122 to be sleeved on the water inlet pipe, thus facilitating the assembly of the separation bracket 1321 on the box body 131.

[0133] Among them, when the elbow 132122 is plugged with the water inlet pipe, a second sealing ring 132124 can be provided between the elbow 132122 and the water inlet pipe to improve the sealing performance after the elbow 132122 is plugged with the water inlet pipe and prevent sewage from leaking out from the connection position or air leakage at the connection position, resulting in a reduction in the air-water separation effect. Among them, the second sealing ring 132124 can be provided on the inner wall of the elbow 132122 that is plugged with the water inlet pipe, or the second sealing ring 132124 can be provided on the outer wall of the water inlet pipe that is plugged with the elbow 132122; when the second sealing ring 132124 is provided on the elbow 132122, the second sealing ring 132124 can be snap-fitted with the elbow 132122 through an elastic force. For example, the second sealing ring 132124 is provided with a plurality of positioning protrusions, and the elbow 132122 is provided with a plurality of positioning holes. The second sealing ring 132124 is provided on the inner wall of the elbow 132122, and the plurality of positioning protrusions are located in the plurality of positioning holes, forming a positioning snap-fit of the second sealing ring 132124 on the elbow 132122; it is beneficial to replace the second sealing ring 132124 during long-term use or when the sealing fails.

[0134] In some embodiments, as Figure 10 shown, in the height direction Z, the height of the outlet of the second air duct 13242 and the inlet of the third air duct 13243 can be the same. By making the height of the outlet of the second air duct 13242 and the inlet of the third air duct 13243 the same, when the sewage and gas are discharged through the outlet of the second air duct 13242, the gas can be promptly turned 180° and discharged upward through the third air duct 13243, improving the air-water separation effect.

[0135] In some embodiments, as Figures 10 to 13As shown, the sewage tank 130 further includes: an upper cover 133, which is fixedly connected to the installation part 13211. By providing the upper cover 133, a seal for the same open end 1313 is formed in connection with the separation component 132.

[0136] Among them, a switch component 137 can be provided on the upper cover 133 to form a switch connection between the sewage tank 130 and the main body 110 of the machine; for example, by providing a push-button switch component 137, a switch connection between the sewage tank 130 and the main body 110 of the machine can be formed, facilitating the disassembly and assembly of the sewage tank 130.

[0137] Among them, the first contact electrode 1383 and the second contact electrode 1384 are exposed through the through holes of the upper cover 133; when the sewage tank 130 is connected to the main body of the machine 100, the first contact electrode 1383 and the second contact electrode 1384 exposed on the upper cover 133 can contact the electrodes on the main body of the machine 100, thereby conducting the controller with the first contact electrode 1383 and the second contact electrode 1384 to form a monitoring circuit.

[0138] Among them, the portions of the first contact electrode 1383 and the second contact electrode 1384 exposed through the through holes of the upper cover 133 can be elastic structures to improve the reliability when contacting the electrodes on the main body of the machine 100. Among them, the elastic structure can be, for example, a metal shrapnel structure.

[0139] In some embodiments, as Figure 14 and Figure 15 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.

[0140] Among them, in the width direction X of the box body 131, the sewage inlet pipe 1322 is provided on the side wall close to one side of the sewage tank 130, and the outlet of the sewage inlet pipe 1322 is inclined towards the side wall on the opposite side of the sewage tank 130. When the sewage in the sewage tank 130 is full, the accumulated sewage in the box body 131 needs to be poured out through the open end 1313. Since the sewage inlet pipe 1322 is fixedly connected to the sewage inlet 1312 on the box body 131, when pouring water from the rear side of the box body 131, there is a phenomenon of sewage flowing back from the sewage suction port, resulting in sewage flowing out from the sewage inlet 1312 at the bottom of the box body 131, which is likely to dirty the shoes and clothes of the user and seriously affect the user experience. In the present disclosure, by making the outlet of the sewage inlet pipe 1322 inclined towards the side wall on the opposite side of the sewage tank 130, the outlet of the sewage inlet pipe 1322 can be completely kept above the liquid level, avoiding sewage flowing out from the sewage inlet 1312 at the bottom of the box body 131 and improving the user experience.

[0141] Among them, as Figure 15As shown, the included 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 included angle ∠A at which the outlet is inclined towards the opposite side wall of the sewage tank 130, can be 20° to 60°, so that the outlet of the sewage inlet pipe 1322 can be completely kept above the liquid level, and at the same time, it does not affect the smoothness of the air duct formed after being connected to the elbow 132122. ∠A can be, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., and the present disclosure does not list them one by one here; of course, ∠A can also be less than 20° or greater than 60°, and the present disclosure does not limit this.

[0142] Among them, the sewage inlet pipe 1322 and the box body 131 can be an integrally formed structure to improve the structural strength of the sewage inlet pipe 1322, and further improve the sealing performance when the sewage inlet pipe 1322 is inserted into the elbow 132122. Of course, the sewage inlet pipe 1322 and the box body 131 can also be a split structure, for example, they are connected together by means such as bonding, welding, threaded connection, snap connection, etc., and the present disclosure does not limit this.

[0143] In some embodiments, a grasping component 136 is provided on the sewage tank 130, and the grasping component 136 is located on the side wall of the box body 131 opposite to the sewage inlet pipe 1322. By providing the grasping component 136, it is convenient to lift the box body 131 to pour out the sewage from the rear side of the box body 131.

[0144] Among them, the grasping component 136 can include a grasping plate, and the grasping plate is connected to the box body 131 through an elastic member; when the grasping plate is not grasped, the grasping plate is in the original position through the elastic member; when the grasping plate is in the original position, it can be in a state basically flush with the outer surface of the box body 131 to avoid foreign objects being easily caught by the protruding grasping plate, and at the same time improve the aesthetic appearance of the sewage tank 130; when the user lifts the sewage tank 130 through the grasping plate, the bottom of the grasping plate can rotate towards the outside of the box body 131 to increase the grasping space and facilitate the user to apply force; when the user releases the grasping plate, the grasping plate can return to the initial position through the elastic restoring force of the elastic member.

[0145] In some embodiments, as Figure 14 and Figure 15 shown, in the width direction X of the box body 131, the side wall of the sewage inlet pipe 1322 close to the sewage tank 130 is provided; at least part of the pipe body of the sewage inlet pipe 1322 extending from the sewage inlet 1312 towards the outlet side of the sewage inlet pipe 1322 has only an accommodation space 1311 between it and the opposite side wall of the sewage tank 130.

[0146] By making at least a part of the pipe body of the sewage inlet pipe 1322 extending from the sewage inlet 1312 towards the outlet side of the sewage inlet pipe 1322 have only a receiving space 1311 between it and the side wall on the opposite side of the sewage tank 130, and there is no receiving space 1311 on one side of at least a part of the pipe body of the sewage inlet pipe 1322 extending from the sewage inlet 1312 towards the outlet side of the sewage inlet pipe 1322, it avoids the situation where sundries are trapped in a narrow space and cannot be taken out, thus avoiding the phenomenon that users manually remove sundries and improving the user experience.

[0147] When the sewage inlet pipe 1322 and the box body 131 can be of an integrally formed structure, at least a part of the pipe body of the sewage inlet pipe 1322 extending from the sewage inlet 1312 towards the outlet side of the sewage inlet pipe 1322 can be used as the side wall of the box body 131. That is, a part of the outline of the sewage inlet pipe 1322 can be shown from the outer contour of the box body 131, and the position of the sewage inlet pipe 1322 reflected on the box body 131 can be a special-shaped structure; this structure can be matched with the positioning structure on the main body 110 of the machine to form the positioning of the sewage tank 130 when assembled on the main body 110 of the machine, so as to improve the assembly accuracy of the sewage tank 130.

[0148] In some embodiments, as Figures 16 to 18 shown, the separation component 132 further includes: a filter element 1323. The filter element 1323 is arranged in the receiving space 1311 and divides the receiving space 1311 into a first receiving space 13111 and a second receiving space 13112 along the height direction Z. The filter element 1323 is provided with an avoidance notch 13234, and the sewage inlet pipe 1322 is located in the avoidance notch 13234.

[0149] By providing the filter element 1323, the filtration of solid sundries in the sewage is formed, so that the sundries in the sewage are filtered out, avoiding the blockage of the sewage outlet in the user's usage scenario by sundries when pouring the sewage. Through the avoidance notch 13234 provided on the filter element 1323, it cooperates with the sewage inlet pipe 1322 to form the filtration of solid sundries, avoiding the sundries from leaking into the second receiving space 13112 below the filter element 1323.

[0150] Among them, the filter element 1323 is connected to the separation bracket 1321, and the filter element 1323 can be taken out simultaneously when taking out the separation bracket 1321 to pour out the filtered sundries.

[0151] 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 is detachably connected to the separation bracket 1321. For example, the connecting rod 13235 and the separation bracket 1321 are detachably connected by means of threaded connection, snap connection, 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 limit this.

[0152] In some embodiments, as Figures 16 to 18 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 disposed closer to the bottom of the box body 131 than the second filter portion 13232. By arranging the first filter portion 13231 closer to the bottom of the box body 131 than the second filter portion 13232, more solid debris can be accommodated on the filter element 1323.

[0153] Among them, a baffle 1316 is provided on the inner wall of the box body 131. The baffle 1316 cooperates with the first filter portion 13231, the second filter portion 13232 and the sewage inlet pipe 1322 to completely shield the box body 131 from the cross section, so that the sewage can only enter the lower second accommodation space 13112 through the filter holes on the filter portion, improving the filtering effect on solid debris.

[0154] Among them, a third sealing ring can also be provided on the part of the filter element 1323 in contact with the inner wall of the box body 131 to reduce the gap at the contact position between 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 taken out, the third sealing ring can be used to scrape the dirt on the inner wall of the box body 131 to improve the cleanliness of the box body 13,

[0155] In some embodiments, as Figure 17 and Figure 18 shown, the first filter portion 13231 is in a flat plate shape. By making the first filter portion 13231 in a flat plate shape, that is, there is no obstruction on the side of the first filter portion 13231 close to the sewage inlet pipe 1322, which is a semi-open structure, and the accumulated debris on the filter portion is easier to pour out from the filter element 1323. Of course, the first filter portion 13231 can also be in a cylindrical structure, and the present disclosure does not limit this.

[0156] Among them, as Figure 17 and Figure 18 shown, side baffles 13233 can 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 the accumulated debris.

[0157] In some embodiments, as Figure 19 shown, the separation component 132 further includes a first gas-water separator 134, and the first gas-water separator 134 is disposed in the third air duct 13243. By arranging the first gas-water separator 134 in the third air duct 13243, the gas and water can be directly separated in the air duct of the sewage tank 130, further improving the gas-water separation effect.

[0158] Among them, as Figure 19 shown, a plurality of filter micropores are arranged in a whole column on the first gas-water separator 134. The gas can pass through the micropores, and the moisture of the gas can be blocked by the micropores to effectively separate the gas and water.

[0159] Among them, 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 through a threaded member or by a snap connection, so as to facilitate the loading, unloading and maintenance of the first gas-water separator 134.

[0160] Among them, the first gas-water separator 134 can be obliquely arranged in the third air duct 13243 to relatively increase the area of the steam-water separation part on the first gas-water separator 134 and improve the gas-water separation ability.

[0161] In some embodiments, as Figure 20 and Figure 21 shown, the separation component 132 further includes a second gas-water separator 135, and the second gas-water separator 135 is disposed at the outlet of the third air duct 13243. The second gas-water separator 135 cooperates with the first gas-water separator 134 to form a secondary filtration, thereby improving the gas-water separation effect; when the second gas-water separator 135 is, for example, a HEPA (High Efficiency Particulate Air Filter) filter, the service life of the second gas-water separator 135 can be increased.

[0162] Among them, the second gas-water separator 135 is detachably connected to the cover plate. For example, it can be detachably connected to the cover plate by a snap connection or through a threaded member, so as to facilitate the loading, unloading and maintenance of the second gas-water separator 135.

[0163] Among them, the second gas-water separator 135 can be obliquely arranged at the outlet of the third air duct 13243 to relatively increase the area of the steam-water separation part on the second gas-water separator 135 and improve the gas-water separation ability.

[0164] The embodiments of the present disclosure also provide a cleaning system, as Figure 22 and Figure 23As 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, and the cleaning device 10 can perform functions such as parking, charging, self-cleaning, sewage discharge, and water replenishment on the base station 20. For the beneficial effects of the cleaning system provided by the present disclosure, please refer to the detailed description in the above embodiment of the cleaning device, which will not be repeated here.
