So set up, when cleaning device 2 dock with basic station 1, drain 242, water injection mouth 2113 and location mouth 2114 on cleaning device 2 dock with sewage mouth 111, upper water gap 12 and reference column 13 on the basic station 1 respectively to can fix cleaning device 2 on basic station 1, and then discharge the dirty in the sewage bucket 24 to basic station 1 in, perhaps make basic station 1 to the clean liquid bucket 23 moisturizing on the cleaning device 2.

As shown in fig. 9 and 11, the sewage bucket 24 includes a front sidewall 2441 adjacent to one side of the main body 21, and an enclosing wall 2442 enclosing the front sidewall 2441, and the front sidewall 2441 and the enclosing wall 2442 together enclose an inner cavity 243 for storing sewage, and the inner cavity 243 communicates with the sewage inlet 2411 and the sewage outlet 242, respectively.

The waste inlet 2411 is positioned adjacent the front side wall 2441 to allow for a location for the rear waste outlet 242 and to increase the size of the interior cavity 243 so that the waste tank 24 can accommodate more waste.

As shown in fig. 6 and 9, the drain 242 of the wastewater tank 24 is located at the rear side of the wastewater inlet 2411 and is exposed downward from the main body 21. So configured, when the cleaning apparatus 2 is docked with the base station 1, the drain 242 is docked with the sewage outlet 111 of the base station 1, and as the cleaning apparatus 2 falls down in a direction approaching the base station 1, the drain 242 can extend into the sewage outlet 111 until the cleaning apparatus is completely seated on the base station 1, it being understood that the longer the length of the drain 242 extending into the sewage outlet 111, the less the probability of dirt splashing to the outside when discharged from the drain 242.

Further, since the drain 242 is located at a rear side position of the sewage bucket 24 with respect to the sewage inlet 2411. When the cleaning device is in butt joint with the base station 1, the sewage outlet 242 is directly in butt joint with the sewage outlet 111 of the base station 1 and is communicated, dirt in the sewage bucket 24 flows into the sewage outlet 111 of the base station 1 under the dead weight, and connecting pipelines such as a water pipe are not required to be additionally arranged between the sewage outlet 242 and the sewage outlet 111, so that the cleaning system has a simple integral structure, and the condition that sundries are accumulated due to the existence of bending parts in the connecting pipelines is avoided, and the smoothness of sewage discharge is ensured.

Further, the center of the sewage inlet 2411 and the center of the sewage outlet 242 are located on the center line of the bottom surface of the sewage bucket 24, that is, both sides of the bottom surface of the sewage bucket 24 are symmetrical with respect to the sewage inlet 2411 and the sewage outlet 242. In one aspect, the dirt inlet 2411 facilitates the communication of the dirt inlet 2411 with the dirt suction pipe 2115 to recover dirt into the dirt receptacle 24 at the front and the dirt outlet 242 facilitates the discharge of dirt from the dirt receptacle 24 into the lower dirt outlet 111 at the rear; on the other hand, the centers of the sewage inlet 2411 and the sewage outlet 242 are located on the central line of the bottom surface of the sewage bucket 24, which is favorable for the stability of the cleaning device when docking with the base station 1, and is favorable for reserving enough space for the water injection ports 2113 and/or the positioning ports 2114 on both sides of the sewage outlet 242, so that the space layout of the docking assembly is optimized.

Further, a center line between the sewage inlet 2411 and the sewage outlet 242 coincides with a center line of the bottom of the sewage bucket 24. The middle line between the sewage inlet 2411 and the sewage outlet 242 refers to the middle vertical line of the connecting line of the sewage inlet 2411 and the sewage outlet 242, when the middle line between the sewage inlet 2411 and the sewage outlet 242 is coincident with the middle line at the bottom of the sewage tank 24, the sewage inlet 2411 and the sewage outlet 242 can have larger width, so that sewage absorption and sewage discharge of the sewage tank 24 are smooth. As shown in fig. 5 and 12, the nozzle of the dirt suction duct 2115 extends upward to the upper end face of the first bearing portion 2111; and the sewage inlet 2411 of the sewage bucket 24 is abutted with the nozzle of the sewage suction pipe 2115. Thus, dirt on the work surface may enter the dirt suction duct 2115 in the fuselage 21 along the dirt suction opening 224 at the floor brush assembly 22, then from the dirt suction duct 2115 into the dirt inlet 2411 of the dirt receptacle 24, and finally into the interior cavity 243 of the dirt receptacle 24.

As shown in fig. 5 and 9, a sewage inlet pipe 241 is further provided in the sewage bucket 24, and one end of the sewage inlet pipe 241 is formed at a bottom of the sewage bucket 24 to form a sewage inlet 2411, and the other end is configured to extend upward of the sewage bucket 24.

That is, in this embodiment, the sewage inlet pipe 241 extends in a vertical direction or in an axial direction of the machine body, and the sewage inlet 2411 and the sewage outlet 242 are located below the communicating port between the sewage inlet pipe 241 and the inner cavity of the sewage bucket 24. So configured, the risk of sewage flowing back onto the work surface through the sewage inlet pipe 241 in the sewage bucket 24 is avoided based on the gravity of the sewage itself.

Specifically, as shown in fig. 9, in one embodiment of the present disclosure, a portion of the front sidewall 2441 of the wastewater tank 24 is configured to participate in enclosing the wastewater inlet pipe 241. This results in an effective saving of material for the wastewater tank 24.

If the cleaning device 2 is separately provided with the sewage inlet pipeline, after a period of use, the sewage inlet pipeline and the gap between the inner walls of the sewage bucket 24 accumulate sewage, so that the sewage bucket is inconvenient to clean and can generate peculiar smell, and the sewage bucket just utilizes the structure of the sewage bucket to form the sewage inlet pipeline 241, so that the problems are well solved, and the use experience of users is improved.

Further, as shown in fig. 12, the included angle R between the dirt inlet duct 241 and the front side wall 2441 is not smaller than 90 °.

So set up, advance dirty pipeline 241 and preceding lateral wall 2441 space enough big be unfavorable for debris to pile up, even pile up debris user and also can clear up through instrument such as brush, can reduce the probability of piling up debris in the sewage bucket 24. If the included angle between the dirt inlet pipe 241 and the front side wall 2441 is an acute angle smaller than 90 degrees, a dead angle is very easy to be cleaned in the acute angle space, and dirt remains.

In this embodiment, compared with the prior art, the upper end nozzle of the dirt suction pipe 2115 is close to the machine body 21, on the horizontal projection plane, the nozzle of the dirt suction pipe 2115 is behind the dirt suction port 224, and the dirt suction pipe 2115 is inclined upwards from the dirt suction port 224 to the nozzle, there is no turning back or bending part, the dirt inlet pipe 241 of the sewage bucket 24 is arranged at the front side wall 2441 matched with the machine body 21, the nozzle of the dirt suction pipe 2115 is in butt joint with the dirt inlet 2411 of the dirt inlet pipe 241 along the inclined upwards trend of the dirt suction pipe 2115, and the negative pressure is formed in favor of the overall trend of the dirt suction pipe 2115.

As shown in fig. 5, 13 and 14, the cleaning apparatus 2 further includes a motor assembly 25, the motor assembly 25 is disposed at a front side of the main body 21 at a position above the cleaning liquid tank 23, and an air inlet passage 251 of the motor assembly 25 is configured to communicate with the sewage tank 24 at a rear side of the main body 21. When the motor assembly 25 is activated, a negative pressure will be created in the waste basket 24, under which the dirt on the working surface is sucked through the dirt suction duct 2115 to the inner cavity 243 of the waste basket 24.

In more detail, as shown in fig. 3 and 4, the body 21 includes a first housing 214 at the rear side of the body 21 and a second housing 215 at the front side of the body 21; the first housing 214 forms a first chamber 2141 (see fig. 14) at the rear side of the main body 21, and the first chamber 2141 is located above the first installation groove 211, i.e., above the sewage tank 24. The second housing 215 forms a second chamber 2151 at the front side of the body 21, and the second chamber 2151 is located above the second mounting groove 212, i.e., above the cleaning liquid tank 23. The motor assembly 25 is located in the second chamber 2151 on the main body 21, that is, the motor assembly 25 is located above the cleaning liquid tank 23, and the motor assembly 25 is disposed offset from the sewage tank 24.

As shown in fig. 5, the air inlet channel 251 of the motor assembly 25 is obliquely extended from the second chamber 2151 to the first chamber 2141 and is further communicated with the sewage bucket 24, so that the air inlet channel 251 is not bent as a whole, and the motor assembly 25 can form a strong negative pressure in the sewage bucket 24, thereby improving the sewage sucking efficiency of the cleaning device 2.

Specifically, as shown in fig. 5 and 15, the rear side of the main body 21 is provided with a first docking surface 213 for being mated with the upper end surface of the sewage bucket 24; a negative pressure port 2131 for communicating with the sewage bucket 24 is provided on the first abutting surface 213; and the air intake passage 251 extends obliquely from the front side of the main body 21 toward the rear side of the main body 21, so as to be in abutting communication with the negative pressure port 2131 on the first abutting surface 213.

As shown in fig. 15, the negative pressure port 2131 is formed by a plurality of holes in the present embodiment, but the negative pressure port 2131 may be a complete opening. It will be appreciated that the negative pressure port 2131, when formed of a plurality of holes, may also provide a filtering function, blocking miscellaneous impurities in the air within the waste water bucket 24, preventing it from entering the motor assembly 25 and affecting the proper operation of the motor.

As shown in fig. 5, the air intake passage 251 extends obliquely from the center position of the bottom of the motor assembly 25, the air exhaust passage 252 extends vertically downward from the edge of the motor assembly 25 away from the center of the motor assembly 25, and the air intake passage 251 is butted with the negative pressure port 2131 on the first butted surface 213 after passing through the air exhaust passage 252. Wherein the passage of the intake passage 251 through the exhaust passage 252 means that the intake passage 251 is disposed through the exhaust passage 252, and the intake passage 251 is not in communication with the exhaust passage 252. Thus, the air inlet of the motor assembly 25 is ensured to be smooth, and the normal air exhaust of the motor assembly 25 is not influenced.

As shown in fig. 5, due to the large size of the motor assembly 25, in the extending direction of the main body 21, the motor assembly 25 at least partially overlaps with the orthographic projection of the cleaning liquid tank 23 on the horizontal plane (the plane approximately perpendicular to the extending direction of the main body); the sewage bucket 24 is partially overlapped with the orthographic projection of the motor assembly 25 on the horizontal plane; more preferably, the cleaning liquid tank 23 is within the front projection of the motor assembly 25. In this way, the thickness of the entire body 21 can be smaller than the sum of the thicknesses of the motor assembly 25 and the sewage bucket 24, thereby reducing the space occupied by the body 21 and making the cleaning apparatus 2 as a whole more lightweight.

Suitably, in the present embodiment, the size of the second chamber 2151 for accommodating the motor assembly 25 is also larger than that of the first chamber 2141, and the second chamber 2151 extends toward the rear side of the body 21 and at least partially overlaps the front projection of the first abutting surface 213 on the horizontal plane, so that the air intake passage 251 of the motor assembly 25 is facilitated to be in abutting communication with the negative pressure port 2131 on the first abutting surface 213.

As shown in fig. 5 and 13, the first docking surface 213 is further provided with an exhaust port 2132 adjacent to a side wall of the sewage bucket 24 for cooperation with the main body 21, the exhaust port 2132 is located directly under the exhaust passage 252, and the exhaust passage 252 of the motor assembly 25 extends vertically downward from an edge of the motor assembly 25 along an axial direction of the motor assembly 25 to dock with the exhaust port 2132 provided on the first docking surface 213. In this way, the air flow discharged from the motor assembly 25 can be discharged from the air outlet 2132 of the first docking surface 213 along the air outlet 252 of the motor assembly 25, and then discharged to the outside from the gap between the main body 21 and the sewage bucket 24, and the compactness of the structure is maximized.

As shown in fig. 14 and 15, in the present embodiment, the cleaning apparatus 2 further includes a circuit board assembly 26, and the circuit board assembly 26 may include a main control board and a charging processing circuit board of the cleaning apparatus 2. The circuit board assembly 26 is vertically mounted within the first chamber 2141. The circuit board assembly 26 is separated from the accommodating space of the motor assembly 25 and is arranged in the first chamber 2141 above the sewage bucket, so that the space layout of the cleaning device is fully utilized, and the circuit board assembly 26 is arranged vertically, so that the transverse space of the machine body 21 can be effectively saved, the required size of the first chamber 2141 can be reduced, the size of the second chamber 2151 is ensured to be larger than that of the first chamber 2141, and the second chamber 2151 can accommodate the motor assembly 25 with larger size. As shown in fig. 11, 16 and 17, in one embodiment of the present disclosure, an upper cover bracket 245 is further provided at the top of the sewage tank 24, and the upper cover bracket 245 includes a water blocking cavity 2452 surrounded by a water blocking housing 2451 and having a lower end opening, and an air outlet passage 2453 isolated from the water blocking cavity 2452; a sewage inlet pipe 241 is also arranged in the sewage bucket 24, and the sewage inlet pipe 241 extends to the upper side of the sewage bucket 24 and into the water retaining cavity 2452; one end of the air outlet passage 2453 extends upward and forms an air outlet 24532 at the top of the sewage bucket 24; the other end extends to the outer side wall of the water blocking cavity 2452 to form an air inlet 24531. In one embodiment of the present disclosure, a filter assembly 2454 may also be provided above the air outlet 24532, the filter assembly 2454 being used to filter out debris and water from the air.

It can be appreciated that the sewage bucket 24 is provided with the water blocking cavity 2452, when the dirt in the dirt inlet pipe 241 flows out from the upper end, the dirt can be blocked in the water blocking cavity 2452 and can not be directly sucked into the air outlet channel 2453 by the motor assembly 25, so that the dirt can be effectively prevented from being sucked into the motor assembly 25 through the air outlet channel 2453, and the motor assembly 25 can be prevented from being unable to work normally due to water inlet.

As shown in fig. 15 and 18, in one embodiment of the present disclosure, a water blocking housing 2451 is formed with an open end at a side adjacent to a front sidewall 2441 of the sewage bucket 24; the open end of the water blocking housing 2451 is sealed with the front sidewall 2441 of the sewage bucket 24 through the sealing strip 2455, so that the sewage inlet passage and the air outlet passage are isolated and independent from each other within the range of the upper cover bracket 245.

So set up, all have preceding lateral wall 2441 or manger plate casing 2451 around the dirty in advancing dirty pipeline 241 to can avoid advancing dirty in the dirty pipeline 241 and be inhaled in motor assembly 25 from manger plate casing 2451 and preceding lateral wall 2441's clearance, thereby guarantee motor assembly 25 can normally work.

As shown in fig. 15, 17 and 18, in one embodiment of the present disclosure, an end of the air outlet passage 2453 adjacent to the air inlet 24531 extends in a horizontal direction on the outer wall of the water blocking cavity 2452 and forms the air inlet 24531 higher than the bottom opening of the water blocking cavity 2452.

So set up, even if some dirt has arrived air-out passageway 2453 department from bottom to top, also can be resisted by the outer wall that air-out passageway 2453 extends along the horizontal direction to can't directly get into in the air-out passageway 2453.

In addition, since the air inlet 24531 is higher than the bottom opening of the water blocking cavity 2452, the middle of the upper end opening of the dirt inlet channel and the air inlet 24531 is blocked by the water blocking housing 2451. Thus, even under the negative pressure formed by the motor assembly 25, the dirt cannot move from the top end opening of the dirt inlet channel to the air outlet channel 2453 directly, so that the dirt can be effectively prevented from entering the air outlet channel 2453.

As shown in fig. 11 and 16, the water blocking cavity 2452 divides the inner cavity of the sewage bucket 24 into a side facing the front side wall 2441 and a side facing away from the front side wall 2441, the air inlet 24531 is positioned on the side facing the front side wall 2441 of the water blocking cavity 2452, the opening of the air inlet 24531 is oriented in line with the opening end direction of the water blocking housing 2451, and the air inlet 24531 is positioned behind the water blocking housing 2451 in the horizontal direction so as to maintain a sufficient gap with the front side wall 2441 to facilitate gas circulation.

As shown in fig. 1 and 17, the air inlet 24531 of the air outlet passage 2453 is located at a front side position in the inner cavity 243 of the sewage bucket 24, and the air inlet 24531 is directed toward the front side direction of the sewage bucket 24, and the opening direction of the air inlet 24531 is directed toward the side wall of the sewage bucket 24, particularly, toward the side wall (relative to the other side wall located below) of the sewage bucket 24 when the cleaning task is performed obliquely toward the cleaning device, particularly, in the present embodiment, the opening direction of the air inlet 24531 is directed toward the front side wall 2441 of the sewage bucket 24.

When the user uses the cleaning device 2, the main body 21 is inclined to the side where the user is located, so that the air inlet 24531 of the air outlet duct 2453 is located at an upper position in the inner cavity 243 of the sewage bucket 24, and the air inlet 24531 is also located in an inclined and upwardly extending state.

Since the dirt in the inner cavity 243 of the sump 24 forms an upper surface in a horizontal direction by the gravity, the air inlet 24531 is kept away from the dirt as far as possible, and is prevented from being sucked into the motor assembly 25 because the dirt approaches the air inlet 24531.

As shown in fig. 16, in one embodiment of the present disclosure, the upper cover bracket 245 is provided at opposite sides thereof with probes 246 for detecting a liquid level, respectively, and the water blocking chamber 2452, the air inlet 24531 of the air outlet duct, and the probes 246 may be sequentially distributed in a radial direction of the sewage bucket 24. When the probe 246 is soaked by the dirt, the cleaning device 2 can send a full water signal to the cleaning device 2, so that the user can be reminded of the fact that the dirt in the sewage bucket 24 is more, and the user is reminded of carrying out sewage.

As shown in fig. 16 and 17, opposite sides of the upper cover bracket 245 are provided with rubber caps 247, and the rubber caps 247 extend in the axial direction of the upper cover bracket 245. In this way, when the front side wall 2441 or the surrounding wall 2442 is assembled with the upper cover bracket 245 along the axial direction of the upper cover bracket 245, the rubber coating 247 can protect the inner wall of the front side wall 2441 or the surrounding wall 2442 and prevent the upper cover bracket 245 from scratching the inner wall of the front side wall 2441 or the surrounding wall 2442.

In this embodiment, the outermost sides of the upper cover bracket 245 are two probes 246, and the encapsulation 247 is located at the outer edges of the two probes 246, so that the rigid probes 246 are prevented from scratching the inner wall of the sewage tank 24 when the upper cover bracket 245 is mounted.

Further, a sealing assembly is provided on the sewage bucket 24 for opening or closing the sewage outlet 242. When the drain 242 is closed, the dirt in the sewage tank 24 is sealed in the sewage tank 24 by the sealing assembly, and cannot flow out of the drain 242; when the drain 242 is opened, the dirt in the sewage bucket 24 is discharged from the drain 242.

The base station 1 is provided with a triggering mechanism for cooperation with the sealing assembly. Specifically, when the cleaning apparatus 2 is docked with the base station 1, the trigger mechanism can be moved to open the sealing assembly to allow dirt within the waste receptacle 24 to flow out through the drain 242, or to close the sealing assembly to close the drain 242.

When the cleaning is completed or the sewage tank 24 is already full, the user needs to place the cleaning device 2 on the base station 1. Then, the triggering mechanism on the base station 1 can move to open the sealing assembly, so that the dirt in the sewage bucket 24 flows out to the inside of the base station 1 through the sewage outlet 242, and is temporarily stored in the sewage tank or directly discharged from the base station 1 through the sewage tank; then, after the dirt in the sewage tank 24 is completely discharged, the trigger mechanism on the base station 1 can re-close the sewage outlet 242, so that the user can take the cleaning device 2 away from the base station 1 to continue cleaning.

In the cleaning device 2 of the present disclosure, dirt can be sealed in the sewage bucket 24 through the seal assembly in the working process of the cleaning device 2, and then when the cleaning device 2 is placed on the base station 1, the sewage in the sewage bucket 24 can be automatically discharged by utilizing the trigger mechanism, and the user does not need to manually perform sewage discharge, so that the user can be prevented from contacting the dirt, and the use experience of the user is improved.

In one embodiment of the present disclosure, drain 242 and seal assembly protrude from the bottom surface of the wastewater tank 24, on the one hand, the capacity of the wastewater tank 24 is not limited, and on the other hand, the protruding drain 242 facilitates insertion into the gap 2112 for facilitating the draining. The trigger mechanism of the base station 1 acts on the sealing assembly in a direction perpendicular to the sewage bucket 24, and the sealing assembly is rotatably opened and closed by the force of the trigger mechanism perpendicular to the sewage bucket 24.

In detail, as shown in fig. 19, the sealing assembly includes a sealing cover 2481 hinged to the sewage bucket 24 and a locker 2482 for locking the sealing cover 2481. As shown in fig. 20, the sealing cover 2481 may be hinged to the bottom of the sewage tank 24 by a rotating shaft, a first elastic device 24814 is provided between the sealing cover 2481 and the sewage tank 24, and after the lock 2482 is separated from the sealing cover 2481, the sealing cover 2481 opens the sewage outlet 242 under the action of the first elastic device 24814. The first elastic means 24814 may be a torsion spring or other elastic means.

The lock 2482 is controlled by the trigger mechanism to move to be separated from the sealing cover 2481, so that the sealing cover 2481 opens the drain 242; the latch 2482 is also configured to be capable of resetting to latch the sealing cover 2481 such that the sealing cover 2481 closes the drain 242.

The latch 2482 is hinged to the sewage bucket 24 through a second elastic means and is configured to be restored to the locking sealing cover 2481 under the force of the second elastic means after the external force is removed. Specifically, in the present embodiment, the latch 2482 is translatably or rotatably provided on the sewage tank 24, and the second elastic means is provided between the latch 2482 and the sewage tank 24; the second elastic means may be a spring or other elastic means.

As shown in fig. 19 and 21, the trigger mechanism includes a trigger push rod 141 and a reset push rod 142, and the trigger push rod 141 can move to push the lock catch 2482 to displace so as to disengage the lock catch 2482 from the sealing cover 2481; the reset push rod 142 can move to match with the sealing cover 2481 and push the sealing cover 2481 to overcome the acting force of the first elastic device 24814 to close the drain 242.

When the sealing cover 2481 needs to be opened, the trigger push rod 141 can move to push the lock catch 2482 to displace, so that the lock catch 2482 is separated from the sealing cover 2481 after moving, and when the lock catch 2482 is separated from the sealing cover 2481, the sealing cover 2481 can open the sewage outlet 242 under the action of the torsion spring. Thus, the dirt in the dirt tank 24 is discharged from the drain 242 by the gravity of the dirt tank, and enters the dirt tank assembly 11 through the sewage outlet 111 on the top surface of the dirt tank assembly 11.

After the dirt in the sewage bucket 24 is completely discharged from the drain 242, the reset push rod 142 can move to be matched with the sealing cover 2481 and push the sealing cover 2481 to move to close the drain 242, and then the lock 2482 can reset to lock the sealing cover 2481 on the drain 242 under the action of the second elastic device so as to close the drain 242.

As shown in fig. 19 and 22, in one embodiment of the present disclosure, a fence 2484 surrounding the drain 242 is further provided at the bottom of the sewage tank 24, and the side of the fence 2484 facing the trigger push rod 141 is an open end into which the trigger push rod 141 and the reset push rod 142 extend, and the bottom of the fence 2484 is lower than the bottom of the drain 242, that is, the fence 2484 extends beyond the drain 242 at the bottom. Thus, during the sewage discharge process, the enclosure 2484 can limit the flow direction of the dirt, and prevent the dirt from splashing around. Furthermore, the sealing cover 2481 can also be hinged to the side wall of the enclosure 2484 by means of a first elastic means 24814.

As shown in fig. 19, the trigger push rod 141 and the reset push rod 142 are in guide fit in the inner cavity of the base station 1, and the trigger push rod 141 and the reset push rod 142 are arranged in parallel; the base station 1 is also provided with a driving gear 143 which is rotatably connected in the inner cavity of the base station 1 and is positioned between the trigger push rod 141 and the reset push rod 142, and two opposite sides of the driving gear 143 are respectively meshed with teeth arranged on the trigger push rod 141 and the reset push rod 142. The trigger push rod 141 and the reset push rod 142 are respectively provided with racks meshed with the driving gear 143, and the trigger push rod 141 and the reset push rod 142 are arranged in parallel and are respectively arranged at two sides of the driving gear 143. When the driving gear 143 rotates, the movement directions of the trigger push rod 141 and the reset push rod 142 are exactly opposite.

Thus, when the driving gear 143 rotates in the counterclockwise direction, the trigger push rod 141 can be moved outward and the reset push rod 142 can be retracted, taking the direction of fig. 19 as a reference; when the drive gear 143 rotates in a clockwise direction, the reset push rod 142 can be moved outward and the reset push rod 142 can be retracted. It can be seen that the base station 1 of the present disclosure can implement the movement of the two push rods of the trigger push rod 141 and the reset push rod 142 through one driving gear 143, so that more driving gears 143 can be omitted, and two driving mechanisms are not required to be provided for separately driving and moving.

As shown in fig. 19, to facilitate movement of the reset pushrod 142 to push the sealing cap 2481 to close the drain 242, in one embodiment of the present disclosure, the sealing cap 2481 has a sloped surface 24811 that gradually extends downward from a position adjacent to the reset pushrod 142 to a position away from the reset pushrod 142 on a bottom end surface thereof, and a planar surface 24812 that connects the sloped surfaces 24811 together. In the process of extending the reset push rod 142, the reset push rod 142 moves to be matched with the inclined plane 24811 at first, so that the sealing cover 2481 is pushed to rotate in the direction of closing the sewage outlet 242, then when the reset push rod 142 pushes the sealing cover 2481 to be horizontal, the reset push rod 142 is in interference fit with the plane 24812, so that an upward pushing force is given to the sealing cover 2481, the lock catch 2482 is guaranteed to better lock the sealing cover 2481 on the sewage outlet 242, and a gap is prevented from being generated between the sealing cover 2481 and the sewage outlet 242.

Application scene two

Since the drain 242 is located at a rear side position of the sewage bucket 24 with respect to the sewage inlet 2411. When the cleaning device is in butt joint with the base station 1, the sewage outlet 242 is directly in butt joint with the sewage outlet 111 of the base station 1 and is communicated, dirt in the sewage bucket 24 flows into the sewage outlet 111 of the base station 1 under the dead weight, and connecting pipelines such as a water pipe are not required to be additionally arranged between the sewage outlet 242 and the sewage outlet 111, so that the cleaning system has a simple integral structure, and the condition that sundries are accumulated due to the existence of bending parts in the connecting pipelines is avoided, and the smoothness of sewage discharge is ensured.

Application scenario three

In the process that the cleaning device 2 is placed on the base station 1 for sewage disposal, because the sewage inlet 2411 is located at the front side position of the sewage bucket 24 relative to the sewage outlet 242, when the cleaning device 2 is placed on the base station 1, the sewage outlet 242 is located at one side close to the base station 1 relative to the sewage inlet 2411, so that the sewage outlet 242 on the sewage bucket 24 is conveniently in butt joint with the base station 1, and the sewage in the sewage bucket 24 can directly enter the sewage outlet 111 of the base station 1 by utilizing self gravity, without independently arranging equipment for sucking the sewage on the base station 1, the sewage can be discharged more cleanly.

Application scene four

When the cleaning is completed or the sewage tank 24 is already full, the user needs to place the cleaning device 2 on the base station 1. Then, the trigger push rod 141 on the base station 1 can move to push the lock catch 2482 to displace, so that the lock catch 2482 moves and then is separated from the sealing cover 2481, and when the lock catch 2482 is separated from the sealing cover 2481, the sealing cover 2481 can open the sewage outlet 242 under the action of the torsion spring. Thus, the dirt in the sewage bucket 24 can be discharged from the sewage outlet 242 under the action of self gravity and enter the sewage tank assembly 11 through the sewage outlet 111 on the base station 1.

Therefore, in the cleaning device 2 of the present disclosure, dirt can be sealed in the sewage tank 24 through the sealing assembly in the working process of the cleaning device 2, and then when the cleaning device 2 is placed on the base station 1, the sewage in the sewage tank 24 can be automatically discharged by using the triggering mechanism, so that the user does not need to manually perform sewage discharge, and the user can be prevented from contacting the dirt, and the use experience of the user is improved.
