[0096] Reference Figures 1 to 46As shown, an embodiment of the present invention provides a cleaning device, which includes a main unit, a sewage tank 1100, a first fluid channel, a negative pressure source 1500 and a water supply tank 1200. The main unit includes a body 1000 and a base 2000. The base 2000 has a receiving cavity 2300, and a roller brush is installed in the receiving cavity 2300 through a drive; the sewage tank 1100 is installed on the main unit, and the sewage tank 1100 has a fluid inlet 1110 and a fluid outlet 1120, and the fluid inlet 1110 is connected to the receiving cavity 2300; the inner wall of the sewage tank 1100 is an arc-shaped inner wall surface or a ring-shaped cross section, and at least one inlet baffle 1130 is provided at the fluid inlet of the sewage tank 1100 for diverting the fluid flowing into the sewage tank 1100. The airflow is divided into multiple beams, and the multiple airflows are made to collide in the sewage tank 1100; the first fluid channel is connected to the accommodating chamber 2300 and the sewage tank 1100 respectively; the negative pressure source 1500 is arranged on the main unit, and the negative pressure source 1500 generates negative pressure to make the dirt on the surface to be cleaned pass through the accommodating chamber 2300 and the first fluid channel in turn and enter the sewage tank 1100. The first fluid channel can play a role in inletting sewage, which is equivalent to a sewage inlet pipe; the water supply tank 1200 is assembled on the main unit, and the water supply tank 1200 is connected to the suction source 1300 and the water distributor 1400 in sequence through the outlet pipe. The water distributor 1400 includes a first distribution pipe 1410 connected to the roller brush and / or a second distribution pipe 1420 for diverting water outside the main unit.

[0097] The fluid inlet 1110 can be provided at the top or the side of the sewage tank 1100, which determines whether the airflow in the accommodating chamber enters the inner cavity of the sewage tank 1100 from the top or the side. The sewage tank 1100 may include a sewage tank body and a sewage tank cover. Both the fluid inlet 1110 and the fluid outlet 1120 may be provided on the sewage tank cover. Therefore, when the fluid inlet 1110 is located at the top of the sewage tank 1100, it may be directly provided on the upper surface of the sewage tank cover at the top of the sewage tank 1100. When the fluid inlet 1110 is located at the side of the sewage tank 1100, it may also be provided on the side surface of the sewage tank cover at the top of the sewage tank 1100, or on the side surface of the sewage tank body. The sewage tank 1100 may be provided with a sewage tank handle, and the fluid inlet 1110 may be located on the side of the sewage tank 1100 . Therefore, the sewage tank handle and the fluid inlet 1110 may be respectively provided on opposite sides of the sewage tank 1100 .

[0098] The negative pressure source is provided with an air distribution structure 1600, the air distribution structure 1600 having an air distribution inlet 1610 and at least two air distribution outlets 1620, the air distribution inlet 1610 being in communication with the fluid outlet 1120, the fluid outlet 1120 being provided with a filter assembly 1630, the filter assembly 1630 being located between the fluid outlet 1120 and the air distribution inlet 1610, and at least two of the air distribution outlets 1620 being in communication with the outside world. The air distribution structure 1600 can be formed on the basis of the negative pressure source 1500, or it can be a structure independent of the negative pressure source 1500 and assembled relative to the negative pressure source 1500. In one embodiment, the air distribution structure 1600 includes an air distribution shell provided on the negative pressure source 1500, the air distribution inlet 1610 being provided at the bottom of the air distribution shell, and two air distribution outlets 1620 being provided on the side of the air distribution shell, the two air distribution outlets 1620 being symmetrically located on both sides of the air distribution shell. Moreover, the negative pressure source 1500 is located above the accommodating cavity, the air distribution structure 1600 is located at the bottom of the negative pressure source 1500, the fluid outlet 1120 is opened at the top of the sewage tank 1100, and the air distribution inlet 1610 is longitudinally connected to the fluid outlet 1120.

[0099] The accommodating chamber can be connected to the fluid inlet 1110 of the sewage tank 1100 through a channel formed on the main unit itself or a separately arranged pipeline. Under the action of the negative pressure source 1500, the air flow flows from the accommodating chamber to the fluid inlet 1110 of the sewage tank 1100, and can enter the sewage tank 1100 from the fluid inlet 1110 on the top or side of the sewage tank 1100. After the sewage is separated and precipitated, under the suction of the negative pressure source 1500, the air flow can flow out from the fluid outlet 1120 of the sewage tank 1100, wherein a filter component 1630 can be provided at the fluid outlet 1120, and the filter component 1630 is located between the fluid outlet 1120 and the air distribution inlet 1610, so that the air flow can flow out after being filtered by the filter component 1630.

[0100] The airflow out of the fluid outlet 1120 will enter the air splitting structure 1600 on the negative pressure source 1500 based on the connection between the air splitting inlet 1610 and the fluid outlet 1120. The air splitting structure 1600 can split the air sucked in by the negative pressure source 1500 into two beams (left and right). Figure 1 and Figure 2As shown by the arrows in the figure, the arrows point to the flow trajectory of the air flow), and the air flows out through the two air outlets 1620 of the air distribution structure 1600, thereby flowing out of the main unit. The two air outlets 1620 have different directions, which can be opposite directions or directions with a certain angle, as long as the directions are different. In one embodiment, a flow gap 1140 can be provided between the outer wall of the sewage tank 1100 and the inner wall of the accommodating cavity. At this time, the two air outlets 1620 of the air distribution structure 1600 can be connected to the upper part of the flow gap 1140, so refer to Figure 2 As shown, the airflow flowing out of the two air outlets 1620 of the air distribution structure 1600 will flow along the flow gap 1140 and then be expelled from the outside. In particular, the two air outlets 1620 are both connected to the upper part of the flow gap 1140. This allows the airflow to flow out of the two air outlets 1620 and then flow longitudinally along the flow gap 1140, flowing from the top to the bottom of the main unit, and finally out of the bottom of the main unit. Because the sewage tank 1100 is installed in front of the main unit, the air is discharged from the front of the main unit. The user stands behind the main unit to operate, so the wind will not blow directly at the user, which also increases the experience. Moreover, the air distribution structure 1600 can change the airflow from one beam to two beams, avoiding the problem of noise caused by excessive concentration of air outlet, which is more conducive to noise reduction of the product. It should be noted that the outlet of the air distribution structure 1600 can be set to multiple according to needs, such as three, four, five or six.

[0101] In one embodiment, an inlet baffle 1130 is provided at the fluid inlet 1110 of the sewage tank 1100. The inlet baffle 1130 can be provided on the sewage tank cover or on the sewage tank body. The inlet baffle 1130 is arranged horizontally or vertically in the inner cavity of the sewage tank 1100. The inlet baffle 1130 blocks the fluid inlet 1110 to a certain extent, so that the airflow entering the sewage tank 1100 can be formed into two or more air beams in different directions after passing through the baffle, or the air beam can be redirected. If the airflow only has one direction when entering the sewage tank 1100 through the fluid inlet 1110, the airflow and water droplets will not be easily separated inside the sewage tank 1100, and can be easily discharged simultaneously from the fluid outlet 1120 of the sewage tank 1100 under the suction of the negative pressure source 1500. Therefore, the inlet baffle 1130 in the sewage tank 1100 can first transfer the incoming airflow before entering the bottom of the sewage tank 1100.

[0102] The inlet baffle 1130 can adopt any structural form to cooperate with the inner wall of the sewage tank 1100, thereby forming an inlet drainage channel 1131 for airflow. Moreover, the inlet baffle 1130 can also cooperate with the position (such as the top or side) of the fluid inlet 1110 on the sewage tank 1100 to ensure that the inlet baffle 1130 blocks the airflow during the process of the airflow passing through the fluid inlet 1110 and entering the sewage tank 1100, and the specific degree or direction of the blocking effect on the airflow. For example, the inlet baffle 1130 can be arranged horizontally in the inner cavity of the sewage tank 1100. In this case, the inlet baffle 1130 An inlet drainage channel 1131 is formed between the inlet baffle 1130 and the inner wall of one side of the sewage tank 1100. The airflow can enter the interior of the sewage tank 1100 through only one inlet drainage channel 1131, or the inlet baffle 1130 can be arranged horizontally in the inner cavity of the sewage tank 1100. At this time, two inlet drainage channels 1131 in opposite directions are formed between the inlet baffle 1130 and the inner walls on opposite sides of the sewage tank 1100. The airflow can be divided into two symmetrical beams after passing through the inlet baffle 1130 and enter the interior of the sewage tank 1100. In addition, those skilled in the art can also set the position of the inlet baffle 1130 according to actual needs, which is not limited here.

[0103] In one embodiment, the inner wall of the sewage tank 1100 is an arcuate inner wall surface, such as a circular inner wall surface, or the inner wall of the sewage tank 1100 has an annular cross-section. When airflow from the receiving chamber flows into the sewage tank 1100 and enters through the fluid inlet 1110 of the sewage tank 1100, if the inner wall of the sewage tank 1100 is an arcuate inner wall surface or annular in cross-section, the two or more airflow streams separated by the inlet baffle 1130 can move along the circular or annular inner wall of the sewage tank 1100, thereby forming a collision within the sewage tank 1100. This prevents the airflow from continuing to fall and mixing with the sewage and waste, thereby agitating the sewage and waste. This effectively prevents the sewage and waste within the sewage tank 1100 from being drawn into the negative pressure source 1500, thereby preventing damage to the negative pressure source 1500 and preventing the sewage and waste from being blown outside the cleaning apparatus, thereby improving the space utilization of the sewage tank 1100. If the inner wall of the sewage tank 1100 is not annular or circular but has other shapes, the collision between the two or more airflows separated by the inlet baffle 1130 will be reduced, and the sedimentation of dirt will not be achieved after the airflow enters the sewage tank 1100. This is because if the inner wall of the sewage tank 1100 is not circular or annular, the direction of the airflow after entering will be chaotic. The direction and angle of the airflow in the sewage tank 1100 make it difficult for the airflow to form a collision and offset each other's kinetic energy, so the sedimentation and separation of dirt and water in the airflow cannot be achieved.

[0104] In addition, the cleaning device can also be composed of a main body, a rotating device 2500 and a locking mechanism 2510. The main body includes a body 1000 and a base 2000. The base 2000 has a accommodating cavity, and a roller brush is arranged in the accommodating cavity. The main body is provided with a driver, and the driver is connected to the roller brush driving. The rotating device 2500 is rotatably assembled on the base 2000 or the body 1000, and the body 1000 is connected to the base 2000 through the rotating device 2500. The locking mechanism 2510 is arranged on the rotating device 2500 and / or the base 2000, and the locking mechanism 2510 is configured to lock the rotating device 2500 at a preset rotation angle.

[0105] Since the rotating device 2500 can rotate relative to the base 2000, the body 1000 can indirectly rotate relative to the base 2000 through the rotation of the rotating device 2500, so that the body 1000 can swing forward or backward relative to the base 2000, and the rotation angle of the body 1000 relative to the base 2000 can be adjusted. The adjustment of the rotation angle of the body 1000 can facilitate the base 2000 to extend into a narrow space for cleaning operations, thereby improving the cleaning efficiency of narrow spaces.

[0106] The rotating device 2500 can form a fixed rotating axis through a structure such as a rotating shaft, so that the fuselage 1000 can be rotatably assembled on the base 2000 through the rotating device 2500. When the fuselage 1000 rotates with the rotating device 2500, the fuselage 1000 can be prompted to achieve the effect of swinging forward or backward. In one embodiment, a rotating groove 2520 is opened on the base 2000, and the rotating device 2500 is rotatably assembled in the rotating groove 2520 through a rotating shaft.

[0107] During the rotation of the rotating device 2500 along the rotating axis, the locking mechanism 2510 can lock the rotating device 2500 when the rotating device 2500 rotates to a preset rotation angle, so that the rotating device 2500 cannot continue to rotate at this rotation angle, thereby allowing the fuselage 1000 to be fixed relative to the base 2000 at this rotation angle. In one embodiment, the rotating device 2500 includes a clamping member 2511 and a clamping position 2512 respectively arranged between the base 2000 and the rotating device 2500, and the clamping member 2511 is clamped and matched with the clamping position 2512. The mutual clamping of the clamping member 2511 and the clamping position 2512 can achieve the locking of the rotating device 2500 at a preset rotation angle. Among them, the clamping part 2511 can be an elastic component, or indirectly assembled through an elastic component, so that the clamping part 2511 can be elastically clamped and matched with the clamping position 2512, and the clamping position 2512 can be a corresponding matching structure such as a groove or a protrusion, as long as it can form an elastic limited clamping with the elastically assembled clamping part 2511.

[0108] In one embodiment, the locking position 2512 is provided on the rotating device 2500, and the locking member 2511 is elastically assembled in the rotating groove 2520 through the elastic telescopic member 2513. The locking member 2511 is elastically engaged with the locking position 2512 through the elastic telescopic member 2513. Therefore, when the rotating device 2500 is assembled and rotated in the rotating groove 2520, it can be locked by the locking mechanism 2510 at a preset rotation angle.

[0109] In one embodiment, the number of the engaging member 2511 and the engaging position 2512 are both one, the engaging member 2511 is located on the front groove wall or bottom groove wall of the rotating groove 2520, and the engaging position 2512 is located on the front portion or bottom portion of the rotating device 2500; and / or the number of the engaging member 2511 and the engaging position 2512 are both two, the two engaging members 2511 are symmetrically arranged on two opposite side groove walls of the rotating groove 2520, and the two engaging positions 2512 are symmetrically arranged on two opposite sides of the rotating device 2500. In addition, the number and position of the engaging members 2511 and the engaging positions 2512 can be set as required and are not limited here.

[0110] In one of the embodiments, a rotating mechanism 2530 is arranged between the rotating device 2500 and the machine body 1000, and the machine body 1000 rotates relative to the rotating device 2500 through the rotating mechanism 2530. For example, the rotating axis of the rotating mechanism 2530 is perpendicular to the rotating axis of the rotating device 2500, and the rotating of the rotating device 2500 can drive the machine body 1000 to realize the forward and backward swinging relative to the base 2000, and the rotating mechanism 2530 can drive the machine body 1000 to realize the left and right rotating relative to the base 2000.

[0111] The rotating mechanism 2530 can have various structures. In one of the embodiments, the rotating mechanism 2530 comprises a ring-shaped recess 2531 and a ring-shaped protrusion 2532 arranged on the rotating device 2500 and the machine body 1000 respectively, and the ring-shaped recess 2531 and the ring-shaped protrusion 2532 are slidingly assembled, and the machine body 1000 rotates relative to the rotating device 2500 through the sliding assembly of the ring-shaped recess 2531 and the ring-shaped protrusion 2532. The user can hold the machine body 1000 and apply a control force to the machine body 1000, so that the ring-shaped protrusion 2532 can rotate circumferentially relative to the ring-shaped recess 2531, and when the ring-shaped protrusion 2532 slides circumferentially relative to the ring-shaped recess 2531, the machine body 1000 can rotate relative to the rotating device 2500, i.e. left and right rotating, and thus indirectly rotate relative to the base 2000, i.e. left and right rotating, which can facilitate the cleaning device to enter some small space areas for work during the work process, and the machine body 1000 needs to rotate to facilitate entering some narrow corners and low surfaces to be cleaned, such as the bottom of the bed, the bottom of the table and other relatively hidden spaces. Compared with the cleaning device whose machine body cannot rotate left and right, the cleaning device disclosed in the present application can obviously have more prominent cleaning effect on narrow areas and facilitate avoiding obstacles during the cleaning process. The forward and backward rotating of the cleaning device disclosed in the present application can better solve the problem that the cleaning device is limited in height, and the left and right rotating can conveniently realize the operation of the cleaning device, and the left and right rotating of the machine body can easily avoid furniture and obstacles. The cleaning device is provided with forward and backward and left and right rotating functions, so that the user can conveniently clean low and narrow areas during the cleaning process, clean without dead angles, and avoid some obstacles encountered during the cleaning process, thereby improving the cleaning efficiency.

[0112] In one embodiment, a detachably connected bottom cover 2533 is provided at the bottom of the fuselage 1000, and a portion of the annular groove 2531 or a portion of the annular protrusion 2532 is respectively provided on the bottom cover 2533 and the bottom of the fuselage 1000. The bottom cover 2533 and the bottom of the fuselage 1000 are assembled to form the annular groove 2531 or the annular protrusion 2532. The separation of the bottom cover 2533 from the fuselage 1000 can break the annular groove 2531. 1 or annular protrusion 2532, the bottom cover 2533 can be assembled with respect to the fuselage 1000 to form a complete annular groove 2531 or annular protrusion 2532. Therefore, when the bottom cover 2533 is separated from the fuselage 1000, the assembly of the fuselage 1000 with the annular groove 2531 and the annular protrusion 2532 on the rotating device 2500 can be facilitated. When the bottom cover 2533 is assembled with respect to the fuselage 1000, the annular groove 2531 and the annular protrusion 2532 can form a stable assembly structure.

[0113] The sewage tank 1100 is arranged on the main unit, and the sewage tank 1100 is connected to the accommodating cavity 2300 of the base 2000. Sewage and dirt enter the sewage tank 1100 after passing through the accommodating cavity 2300. The water supply tank 1200 is arranged on the main unit, and the water supply tank 1200 is connected to the suction source 1300 and the water distributor 1400 in sequence through the outlet pipe 1370. The water distributor 1400 includes a first distribution pipe 1410 connected to the roller brush and / or a second distribution pipe 1420 for diverting water outside the main unit.

[0114] In one embodiment, the water supply tank 1200 has a box top 1310 and a box bottom 1320, and the water supply tank 1200 has a water storage cavity. The water storage cavity of the water supply tank 1200 is divided into at least two cavity sections 1330 from the box top 1310 to the box bottom 1320. In the direction from the box top 1310 to the box bottom 1320, the cross-sectional areas of the multiple cavity sections 1330 gradually decrease, wherein the cross-sectional area is perpendicular to the direction from the box top 1310 to the box bottom 1320.

[0115] The gradual reduction in the cross-sectional area of ​​the multiple inner cavity sections 1330 of the water supply tank 1200 can be specifically manifested as the width of the different inner cavity sections 1330 gradually decreasing, that is, the width of the multiple inner cavity sections 1330 of the water supply tank 1200 gradually decreases in the direction from the tank top 1310 to the tank bottom 1320. When the water supply tank 1200 is installed in the main unit, the design of different cross-sectional areas in the multiple inner cavity sections 1330 can achieve a faster water outflow speed in the inner cavity sections 1330 with smaller cross-sectional areas compared to the uniform cross-sectional area of ​​the water supply tank 1200 as a whole. After the water level drops, the water outflow speed of the water supply tank 1200 can still be ensured to remain relatively constant, and the water in the water supply tank 1200 will not be significantly reduced due to the reduction in water volume. This can better improve the water outflow efficiency of the water tank, reduce the impact on the water outflow speed, make the water outflow speed of the water supply tank 1200 more uniform and stable, and improve the cleaning efficiency of the cleaning equipment.

[0116] A water outlet structure can be provided on the water supply tank 1200, and the water outlet structure is provided at the bottom 1320 of the water supply tank 1200. The water outlet structure includes a sealing member 1350 and a water outlet 1360 and an air inlet 1341 connected to the water storage cavity. The sealing member 1350 is used to elastically block the water outlet 1360. Therefore, when the water supply tank 1200 is separated from the main unit, the sealing member 1350 can use elastic force to block the water outlet 1360, so that the water inside the water supply tank 1200 cannot flow out from the water outlet 1360. When the water supply tank 1200 is assembled with the main unit, a corresponding structure can be provided to overcome the elastic force of the sealing member 1350, so that the sealing member 1350 releases the blockage of the water outlet 1360, and then the water in the water supply tank 1200 can flow out through the water outlet 1360 and be supplied to the roller brush or the outside of the main unit under the driving action of the suction source 1300.

[0117] In one embodiment, the water tank structure includes a tank cover 1340, the water outlet 1360 is opened on the tank bottom 1320, the tank cover 1340 is arranged on the water outlet 1360, the tank cover 1340 is provided with an external interface 1343 connected to the water outlet 1360, the blocking member 1350 is arranged on the tank cover 1340, and the blocking member 1350 is used to elastically block the external interface 1343, thereby blocking the water outlet 1360. The air inlet 1341 is opened on the box cover 1340, and a top opening portion 1354 is provided on the main unit. The water supply tank 1200 is installed on the main unit. The top opening portion 1354 is in abutment with the blocking member 1350 and is used to push open the blocking member 1350 to open the water outlet 1360. At this time, the top opening portion 1354 serves as a structure for overcoming the elastic force of the blocking member 1350 and can be adapted to the structure of the blocking member 1350, such as a columnar or protruding structure.

[0118] The box cover 1340 can be assembled on the water outlet 1360 of the water supply tank 1200 through a threaded structure, and the blocking member 1350 is set on the box cover 1340. After the box cover 1340 is screwed off, the water outlet 1360 of the water supply tank 1200 can also be used as a water inlet for replenishing water into the water storage cavity of the water supply tank 1200, which is convenient for adding water to the water supply tank 1200 and does not require an additional independent water inlet to be opened on the water supply tank 1200. Of course, the blocking member 1350 elastically assembled on the box cover 1340 can also be directly designed at the water outlet 1360 position of the water supply tank 1200, thereby not designing the box cover 1340 and designing an independent water outlet 1360. Those skilled in the art can select the corresponding design structure according to their needs, and this is not limited here.

[0119] In one embodiment, a limiting platform 1351 is provided in the external interface 1343, and a limiting portion 1352 is provided on the blocking member 1350. The blocking member 1350 is elastically assembled in the external interface 1343 through an elastic member 1353. The limiting portion 1352 of the blocking member 1350 elastically abuts against the limiting platform 1351 through the elastic force exerted by the elastic member 1353, wherein the limiting portion 1352 and the limiting platform 1351 elastically abut against each other to block the external interface 1343.

[0120] The surfaces where the limit platform 1351 and the limit part 1352 abut against each other can be mutually matched planes or mutually matched inclined surfaces. When the limit platform 1351 and the limit part 1352 abut against each other and the surface of the limit platform 1351 and the surface of the limit part 1352 fit together, a good seal can be formed on the external interface 1343, and then the water outlet 1360 is blocked by the blocking of the external interface 1343, so that the water in the water supply tank 1200 cannot flow out from the water outlet 1360. Only when the elastic force exerted by the elastic member 1353 is overcome, the limit part 1352 of the blocking member 1350 and the limit platform 1351 will separate. Even if the surface of the limit platform 1351 and the surface of the limit part 1352 are separated from each other, the contact and mutual contact state causes the external interface 1343 to be opened, and then the water outlet 1360 is opened, so that the water in the water supply tank 1200 flows out from the water outlet 1360.

[0121] In one embodiment, the water tank structure includes a one-way air valve 1342, which is arranged on the air inlet 1341. The one-way air valve 1342 only allows gas to enter the water storage cavity along the air inlet 1341. The one-way air valve 1342 can ensure that the air outside the water supply tank 1200 can enter the water storage cavity of the water supply tank 1200, while the water in the water storage cavity will not flow out of the water supply tank 1200 through the air inlet 1341. The one-way air valve 1342 can be tubular, and the bottom of the one-way air valve 1342 can form a V shape. The inner tube walls on the opposite sides of the V-shaped tube section are in close contact with each other under normal conditions and can only be separated under the pressure value formed when the suction source 1300 is started. Therefore, the suction source 1300 When water is continuously pumped, the negative pressure in the water supply tank 1200 continues to increase. When the air pressure outside the water supply tank 1200 on the one-way air valve 1342 is greater than the water pressure inside the water supply tank 1200 on the one-way air valve 1342, the air outside the water supply tank 1200 can enter the water supply tank 1200 through the one-way air valve 1342 along the air inlet 1341 to replenish air (intake) the water supply tank 1200. When the air pressure inside the water supply tank 1200 is balanced with the air pressure outside the water supply tank 1200, the one-way air valve 1342 can be closed under the pressure of the water pressure inside the water supply tank 1200, that is, the inner pipe walls on the opposite sides of the V-shaped pipe section fit together and seal, so that the one-way gate valve can be closed to prevent the water in the water supply tank 1200 from flowing out of the water supply tank 1200 through the air inlet 1341.

[0122] In one embodiment, the water tank structure includes a first filter element, which is arranged at the water outlet 1360, so that the water in the water supply tank 1200 can be filtered and then flow out through the water outlet 1360, preventing solid matter in the water supply tank 1200 from clogging the water outlet 1360 and the downstream pipeline.

[0123] An elastic snap-fit ​​structure 1390 may be provided on the water supply tank 1200, and the water supply tank 1200 may be configured to be detachably mounted on the host of the cleaning device through the elastic snap-fit ​​structure 1390. When the water supply tank 1200 is installed on the host, the elastic snap-fit ​​structure 1390 may more firmly connect the water supply tank 1200 and the host, and the elastic snap-fit ​​structure 1390 may generate a sound when the water supply tank 1200 is connected to the host, and the sound may remind the user that the water supply tank 1200 has been installed on the host, thereby improving the user's usage experience.

[0124] In one embodiment, the water tank structure includes at least one first one-way valve 1430, which is connected between the suction source 1300 and the water distributor 1400. The first one-way valve 1430 can connect the suction source 1300 and the water distributor 1400 at the pressure value generated when the suction source 1300 is started. The suction source 1300 can be a water pump. When the suction source 1300 is turned on, the water in the water supply tank 1200 can be supplied to the water distributor 1400, thereby generating a higher water pressure value. Only then can sufficient water pressure be generated to flush open the first one-way valve 1430. When the suction source 1300 stops, the water in the water supply tank 1200 cannot generate sufficient water pressure value, and thus cannot flush open the first one-way valve 1430, so that when the host is shut down or stops working, the water in the water supply tank 1200 cannot pass through the first one-way valve 1430.

[0125] When there is residual water in the pipeline between the first one-way valve 1430 and the water distributor 1400, the first one-way valve 1430 can prevent the water in the water supply tank 1200 from being transported downstream. At this time, the end of the pipeline with water downstream of the first one-way valve 1430 is closed, and one end of the water distributor 1400 is connected to the air. Under the action of atmospheric pressure, the sealing effect of the first one-way valve 1430 can prevent the water in the pipeline between the first one-way valve 1430 and the water distributor 1400 from flowing out of the main unit, thereby solving the water leakage problem and ensuring the cleanliness of the floor.

[0126] In one embodiment, the water tank structure includes at least one second one-way valve 1440, which is disposed on the first distribution pipe 1410 and / or the second distribution pipe 1420. The second one-way valve 1440 is capable of opening the first distribution pipe 1410 and / or the second distribution pipe 1420 at the pressure generated when the suction source 1300 is activated. When the first one-way valve 1430 is closed, the second one-way valve 1440 can close one end of the first distribution pipe 1410 or the second distribution pipe 1420 and open the other end. Under the influence of atmospheric pressure, no matter how the height or horizontal inclination of the first distribution pipe 1410 or the second distribution pipe 1420 changes, that is, no matter how the main unit shakes, residual water in the main unit will not flow out through the first distribution pipe 1410 or the second distribution pipe 1420, thereby preventing water leakage after the main unit is shut down or the suction source 1300 stops working.

[0127] The design principle is that when both ends of a water pipe are open, the water in the pipe will leak out as long as the heights of the two ends of the pipe are at different heights. However, if one end of the pipe is blocked, no matter how the pipe is placed, whether the pipe is in a vertical or horizontal state, even if there is a height difference between the two ends of the pipe and they are not at the same height position, the water in the pipe will still not leak out.

[0128] It should be noted that the one-way valve 1342, the first one-way valve 1430 or the second one-way valve 1440 can all be soft one-way valves, mechanical spring valves or electronic valves. For example, when a soft one-way valve is used, the one-way valve 1342, the first one-way valve 1430 or the second one-way valve 1440 can include a main pipe section 1431 and a flexible pipe section 1432, the inner cavity of the flexible pipe section 1432 is connected to the inner cavity of the main pipe section 1431, the inner pipe walls on the opposite sides of the flexible pipe section 1432 are fitted and closed to each other, and the opposite sides of the flexible pipe section 1432 are closed. The inner tube wall can only be separated under the pressure value formed when the suction source 1300 is started. Therefore, the air pressure or hydraulic pressure value formed when the suction source 1300 is started can prompt the soft one-way valve to open, or, for example, when a mechanical spring valve is used, the air pressure or hydraulic pressure value is greater than the elastic force of the spring in the mechanical spring valve, the gas or liquid can flow out of the mechanical spring valve. For example, when an electronic valve is used, the one-way air valve 1342, the first one-way valve 1430 or the second one-way valve 1440 can be automatically controlled to close when the main unit is turned off or the water pump is not working.

[0129] In one embodiment, a jet port 2310 connected to the first distribution pipe 1410 is provided in the accommodating cavity 2300, and the angle between the jet direction of the jet port 2310 and the radial center line of the roller brush is an acute angle. The radial center line is perpendicular to the central axis of the tube brush, and the two ends of the roller brush are symmetrical with respect to the radial center line. At this time, the jet direction and the radial center line are at an acute angle, which can expand the area of ​​the jet and make the water sprayed more evenly on the roller brush. If the jet direction and the radial center line do not form an acute angle, for example, when the jet direction is parallel to the radial center line, the jet port 2310 can only spray to a point on the roller brush when spraying along the radial center line of the roller brush, and can form a circle area at most after the roller brush rotates, and cannot spray evenly at first.

[0130] In one embodiment, the cleaning device includes a roller brush cover 2400, which is assembled on the base 2000. The roller brush cover 2400 and the base 2000 form the accommodating chamber 2300. The inner wall of the roller brush cover 2400 is in contact with at least a portion of the bristles of the roller brush. The bristles of the roller brush can be made of fluff or soft fiber material. The contact between the roller brush cover 2400 and at least a portion of the bristles of the roller brush can be expressed as direct contact between the roller brush cover 2400 and the bristles of the roller brush, or as a distance of 0mm-5mm between the roller brush cover 2400 and the bristles of the roller brush.

[0131] When the roller brush cover 2400 is fitted to the bristles of the roller brush, friction and squeezing forces are generated between the roller brush, the roller brush cover 2400, and the water. This friction and squeezing force can clean the surface of the roller brush and the roller brush cover 2400, ensuring that the roller brush and the roller brush cover 2400 are always clean during operation and even after the cleaning device self-cleans. If the roller brush and the roller brush cover 2400 are not fitted, it will be difficult to keep the roller brush or the roller brush cover 2400 clean during operation and after the cleaning device self-cleans.

[0132] In one embodiment, the cleaning device includes a leaking pipe 1380, which is connected to the water storage cavity of the water supply tank 1200. The inlet of the leaking pipe 1380 is located at the lowest position of the water storage cavity, so that the residual water in the water storage cavity of the water supply tank 1200 can be discharged through the leaking pipe 1380. At this time, a corresponding water sink can be set on the main unit, and the water discharged from the leaking pipe 1380 can be collected through the water sink.

[0133] In one embodiment, the cleaning device includes a second filter element disposed at the air outlet of the sewage tank 1100 , so that the second filter element can filter the airflow in the sewage tank 1100 and then discharge it outside the main body of the cleaning device.

[0134] In one embodiment, the cleaning device includes a base 3000, a power supply 3100 and a control panel. The base 2000 and the base 3000 can be assembled separately. A heater 3400, a second fluid channel 3500 and a hot air outlet 3600 are provided in the base. The second fluid channel 3500 is provided between the heater 3400 and the hot air outlet 3600. The base has a blower 3700, which can guide the hot air through the second fluid channel 3500. The second fluid channel 3500 is equivalent to the hot air channel in the base. A first charging contact 3200 is provided on the base 3000. The first charging contact 3200 is configured to be used for connecting to an external power supply. The power supply 3100 is provided on the host. The power supply 3100 is a rechargeable power supply 3100. ; A second charging contact 3300 is provided on the base 2000, and the second charging contact 3300 is electrically connected to the power supply 3100. The first charging contact 3200 and the second charging contact 3300 are configured to be electrically connected when the base 2000 is assembled on the base 3000, so as to charge the power supply 3100 using the external power supply. The control panel is electrically connected to at least the power supply 3100, the negative pressure source 1500 and the suction source 1300. The control panel has a self-cleaning function button, and the self-cleaning function button is electrically connected to the brake assembly 2200. The self-cleaning function button is configured to start the self-cleaning working mode and turn off the ultraviolet generator 2100 through the brake assembly 2200 in the self-cleaning working mode.

[0135] When the base 2000 of the cleaning device is placed on the base 3000, the user can press the self-cleaning function button, and the control panel can control the cleaning device to start the self-cleaning working mode through the corresponding control system. In the self-cleaning working mode of the cleaning device, the power supply 3100 can power on the negative pressure source 1500, the driving motor, the suction source 1300, etc. The suction source 1300 can control the clean water in the water supply tank 1200 to be delivered to the roller brush through the water outlet pipeline 1370, and the driving motor drives the roller brush to rotate, forming self-cleaning of the roller brush. After the negative pressure source 1500 is started, the suction force of the negative pressure source 1500 can suck the stains remaining on the roller brush or the cleaning device into the sewage tank 1100. Specifically, when the self-cleaning working mode of the cleaning device is started, the cleaning device enters the drying and cleaning mode. In the drying and cleaning mode, the driver is configured to drive the roller brush to rotate, the suction source is configured to drive the cleaning medium stored in the water supply tank to be provided to the roller brush, the roller brush rotates and self-cleanses with the cleaning medium, the heater 3400 is configured to heat at least a portion of the gas flowing in the second fluid channel 3500 to form high-temperature gas in the self-cleaning working mode, the high-temperature gas is blown to the roller brush through the hot air outlet 3600, and the negative pressure source is configured to be able to drive the high-temperature gas to flow along the second fluid channel 3500 and the first fluid channel.
