The control circuit 17 may be an MCU, or may be a circuit board including an MCU, and serves as a processing center of the cleaning apparatus 100.

The walking assembly 12 may include a driving mechanism 121 and a rolling wheel mechanism 122, the driving mechanism 121 is used for driving the rolling wheel mechanism 122 to rotate, and the walking assembly can walk on the working surface of the cleaning device 100. The drive mechanism 121 is, for example, a motor. The rolling wheel mechanism 122 includes, for example, two first rolling wheels 1221 and one second rolling wheel 1222. As shown in fig. 5, two first rotating wheels 1221 may be provided at intervals at the bottom 111 of the main body 11. The two first rotating wheels 1221 can be coaxially connected to serve as a main driving wheel, that is, the driving mechanism 121 can directly drive the two first rotating wheels 1221 to rotate. As shown in fig. 5, the second rotating wheel 1222 may be disposed at the bottom 111 of the dust box 20, and when the first rotating wheel 1221, which is a driven wheel, is driven to travel, the second rotating wheel 1222 is pushed to travel.

The sweeping assembly 13 may include an edge sweep 131 and an edge sweep motor 132 connected to the edge sweep 131. The side sweeper 131 may be disposed at the bottom 111 of the main body 11, and the side sweeper motor 132 may be used to drive the side sweeper 131 to rotate, such that the side sweeper 131 contacts a working surface (e.g., a floor) of the cleaning apparatus 100 and cleans the floor by rotating. The positional relationship between the side-scan motor 132 and the side-scan motor 131 shown in fig. 4 is merely illustrative, and the structure, position, connection, transmission, operation, and the like between the two are not limited. The driving mechanism 121 of the traveling assembly 12 and the side-sweep motor 132 of the sweeping assembly 13 may be the same driving component, i.e., they share the same set of driving system. The control circuit 17 may also control the operation of the edge-sweep motor 132, such as rotational speed control, frequency control, steering control, and the like.

As shown in fig. 5, the main body 11 may be provided with a dust suction port 114, a connection port 115, and an air discharge port 116. The dust suction port 114 communicates with the connection port 115. After the apparatus body 10 and the dust box 20 are assembled, the connection port 115 may communicate with the inside of the dust box 20. The dust suction port 114 may also communicate with the interior of the dust box 20. The dust suction port 114 may be opened at the bottom 111 of the main body 10, that is, at the bottom side of the main body 10, and may be disposed toward a working surface (e.g., floor) of the cleaning apparatus 100, so as to suck dust or garbage on the working surface.

As shown in fig. 6 and 7, the peripheral side 113 of the main body 11 may partially surround to form an accommodating area 1130, which may be partially surrounded or similar to a semi-surrounded shape, and may be adapted to the shape of the dust box 20. The receiving area 1130 receives the dust box 20 so that the dust box 20 can be assembled with the apparatus body 10. The connection port 115 is opened on the peripheral side 113 and faces the accommodation area 1130. The air outlet 116 may be opened on the peripheral side 113 and spaced apart from the connection port 115. For example, the receiving area 1130 is substantially U-shaped, the connection port 115 may be opened at the bottom of the U-shape of the receiving area 1130, that is, the peripheral side 113 faces the middle position of the receiving area 1130, and the exhaust port 116 may be opened at two sides of the U-shape of the receiving area 1130, that is, the peripheral side 113 faces two side positions of the receiving area 1130. The device body 10 may have a body passage. For example, the passage formed by the dust suction port 114, the connection port 115, and the exhaust port 116 may be a main passage. The body passage may be a continuous passage or a discontinuous passage.

The cleaning assembly 13 may further include a rolling brush 133, and the rolling brush 133 may contact the working surface of the cleaning device 100 in a rolling manner, so as to roll up the garbage objects such as hair and paper scraps on the working surface. The rolling brush 133 can be rotatably disposed in the dust suction port 114, so that the rolling brush can curl and adsorb garbage objects during the dust suction process through the dust suction port 114, thereby improving the cleaning efficiency.

As shown in fig. 5, the suction assembly 14 may include a fan 141. The fan 141 may be disposed adjacent to the air outlet 116, and the fan 141 may form an air flow sequentially passing through the dust suction port 114, the connection port 115, the dust box 20, and the air outlet 116, so that the dust suction port 114 has a suction force capable of sucking dust or garbage on the work surface. The number of fans 141 and the number of exhaust vents 116 may be the same. For example, if the number of the exhaust ports 116 is two, the number of the fans 141 may be two. Of course, the dust collection assembly 14 may also include a filter member such as a filter screen, for example, disposed between the exhaust outlet 116 and the dirt box 20, so that larger debris or particles can be retained in the dirt box 20. The control circuit 17 may also control the operation of the fan 141, such as speed control, duration control, and the like.

Of course, the dust suction port 114 may be opened on the peripheral side 113 of the apparatus main body 10. The receiving area 1130 may be used to receive the dirt tray 20, and the dirt tray 20 may be used to collect garbage and other objects. After objects such as trash are retained in the dust box 20, the airflow flows out through the air outlet 116.

The sweeping assembly 13 and the suction assembly 14 may cooperate with each other. For example, the dust suction port 114 may be disposed adjacent to the side sweeper 131 so that the dust or dirt swept out by the rotation of the side sweeper 131 can be sucked into the dust box 20.

The battery assembly 15 is used to power the entire cleaning device 100. Specifically, the battery assembly 15 may include a battery 151 and a charging terminal 152, wherein the charging terminal 152 is electrically connected to the battery 151. The charging stand can charge the battery 151 through the charging terminal 152. The charging terminal 152 may be disposed on the bottom portion 111 of the body portion 11, may be exposed on the surface of the bottom portion 111 of the body portion 11, and may be contacted.

The sensing assembly 16 can be used to transmit and receive corresponding signals to enable communication and interaction with other devices around the cleaning device 100. For example, the sensing assembly 16 may include at least one infrared sensor (not shown), and the infrared sensor may transmit and receive a corresponding infrared signal (infrared light), decode the infrared signal to obtain information, instructions, etc. carried by or corresponding to the signal, so as to avoid an obstacle, communicate with a recharging seat, and the like. The sensing assembly 16 may also include one or more of a crash sensor (not shown), a distance sensor (not shown), an image sensor (not shown), and the like. Specifically, the sensing assembly 16 may receive an infrared signal transmitted by the refill seat, and then enable the cleaning device 100 to perform an operation corresponding to the infrared signal. For example, the control circuit 17 decodes the infrared signal to obtain corresponding information or instructions, and then controls the operation of the walking assembly 12 according to the corresponding information or instructions, so that the cleaning device 100 moves to the charging seat for charging.

As shown in fig. 6 and 7, the cleaning device 100 may further be provided with a scrubbing mechanism, such as a scrubbing member 134. The wiper 134 is used to clean the working surface of the cleaning apparatus 100, and may be provided to the apparatus body 10. For example, the mop 134 may be disposed on the bottom 111 of the body 11. In some embodiments, the wiper 134 may replace the edge brush 131, and the edge brush motor 132 may drive the wiper 134 to rotate, thereby performing wiping cleaning on the corresponding cleaning region. In this regard, the mop 134 may be circular or circular-like in shape. In other embodiments, the mop 134 may be disposed at other regions of the bottom 111 of the main body 11, and spaced apart from the first rotating wheel 1221, the edge broom 131, and the roller brush 133. In this regard, the mop 134 may assume a shape that is compatible with the other areas. During cleaning of the work surface by the cleaning device 100, the wiper 134 can contact the work surface to wipe the work surface for cleaning. The mop 134 is, for example, a mop, a wet wipe, or a sponge.

The structure of the apparatus body 10 described above is merely an example, and is not limited to the above example structure. Of course, the apparatus main body 10 in the present embodiment may also be an apparatus main body of an existing cleaning apparatus, such as a corresponding main body of an existing intelligent cleaning robot, an intelligent dust-collecting robot, or the like.

As shown in fig. 8 to 10, the dust box 20 may be formed with a receiving cavity 210, and an air outlet 211 and a dust inlet 212 communicating with the receiving cavity 210. The dust box 20 may further have a dust outlet 213, and the dust outlet 213 is communicated with the accommodating cavity 210.

Specifically, when the dust box 20 and the apparatus body 10 are connected, the connection port 115 communicates with the accommodation chamber 210, and the air outlet 211 may be in contact with the air outlet 116. When the fan 141 works normally, the air flow sequentially flows from the dust suction port 114, the connection port 115, the accommodation chamber 210, the air outlet 211 and the air outlet 116. The dust inlet 212 may be coupled to the connection port 115 such that the airflow drawn in by the dust suction port 114 enters the accommodating chamber 210 through the connection port 115 and the dust inlet 212. The dust inlet 212 and the air outlet 211 may be located on different sides of the dust box 20. The number of the air outlets 211 can be at least two, and the at least two air outlets 211 are arranged at intervals. The dust outlet 213 is used for communicating with the base station 300. Specifically, when the cleaning apparatus 100 is carried on the base 320, the dust outlet 213 may be docked with and communicate with the suction inlet 301, so that the base station 300 can suction the garbage objects in the accommodating chamber 210 through the dust outlet 213. That is, the dust box 20 may be formed with a dust box passage for communicating with the main body passage of the apparatus main body 10. The dust inlet 212 and the air outlet 211 respectively form a passage with the dust outlet 213, i.e. a passage of the dust box. The main body passage and the dirt box passage communicate with each other to form a second airflow passage 402. Thus, at least one of the suction port 114 and the exhaust port 116 can serve as an inlet of the second airflow path 402, i.e., an airflow inlet, during suction. Of course, during the suction process, one of the suction opening 114 and the exhaust opening 114 may be blocked, and the other may be used as an inlet of the second airflow path 402. The dust outlet 213 may be an outlet of the second airflow channel 402, i.e. an airflow outlet.

In some embodiments, the dust box 20 may not be provided with the dust outlet 213. When the base station 300 sucks the garbage objects in the cleaning device 100, the dust suction port 114 can serve as an outlet of the second airflow path 402, the garbage objects in the accommodating chamber 210 can flow out from the dust suction port 114 into the base station 300 along with the airflow, and the air exhaust port 116 can serve as an inlet of the second airflow path 402. Thus, the suction opening 114 can be an inlet of the cleaning device 100 for cleaning dust, and an outlet of the second airflow path 402 when the base station 300 sucks in the garbage in the cleaning device 100.

Taking the number of the air outlets 211 as two for example, the dust inlet 212 and the two air outlets 211 are disposed at an interval and located on different sides of the dust box 20, wherein the two air outlets 211 are respectively located on two opposite sides of the dust box 20, and the dust inlet 212 is located between the two air outlets 211. In this embodiment, each air outlet 211 may be physically divided into a plurality of air outlet regions, for example, each air outlet 211 may be divided into a plurality of air outlet regions by criss-cross rods. In fig. 9, one outlet 211 is divided into two outlet regions.

Through setting up two air outlets 211 and being located the both sides face of the back of the body that dirt box 20 was held in, dust inlet 212 is located between two air outlets 211, can make two wind channels that the inside formed of dirt box 20 for suction is stronger, the air current is more balanced, has guaranteed to carry out effectual synergism between two fans 141, but also can reduce the produced noise of air current.

The positions of the air outlets 211 correspond to the positions of the air outlets 116, and each air outlet 211 corresponds to at least one fan 141, that is, each air outlet 211 is sucked by a different fan 141.

In some embodiments, as shown in fig. 9 and 10, the dirt box 20 can be formed with a tunnel cavity 214. The passage chamber 214 and the accommodating chamber 210 are provided at intervals in the thickness direction of the dust box 20. For example, the dust box 20 may have a substantially flat outer shape with a thickness direction. The receiving chamber 210 and the passage chamber 214 are spaced apart in the thickness direction, and may be stacked, for example. The airflow entering through the dust inlet 212 flows into the passage cavity 214 after passing through the accommodating cavity 210. Specifically, the dust box 20 may be formed with a communication hole 215 that communicates the housing chamber 210 and the passage chamber 214. The air outlet 211 communicates with the passage cavity 214. When the cleaning device 100 sucks up the garbage, the airflow enters the channel cavity 214 from the accommodating cavity 210 through the communication hole 215, and then can flow to the air outlet 211 from the corresponding airflow path. As shown in fig. 10, a filter member 216 may be provided in the communication hole 215, and the filter member 216 may be used to filter the air flowing to the channel chamber 214 through the receiving chamber 210. Specifically, when the cleaning device 100 sucks up the garbage, the filter member 216 can filter the airflow flowing from the housing chamber 210 to the passage chamber 214 through the communication hole 215, so that the garbage object can be left in the housing chamber 210.

The channel cavity 214 is arranged to be communicated with the air outlet 211, so that the circulating space in the dust box 20 is increased. Further, arrangement and arrangement of the at least two air outlets 211 are facilitated, at least two air flow paths are formed by cooperation of the air outlets 211 and the fan 141, and the fan 141 does not directly suck air in the accommodating chamber 210 but sucks the air through the channel chamber 214, so that garbage deposition in the accommodating chamber 210 is facilitated, and the suction force and the cleaning effect of the dust box 20 are further improved.

The dust outlet 213 communicates with the accommodating chamber 210 without communicating with the passage chamber 214. In other words, the dust outlet 213 communicates with the passage chamber 214 via the accommodation chamber 210 and the communication hole 215. When the base station 300 sucks the garbage objects in the dust box 20, the cleaning device 100 forms corresponding airflow channels, i.e., the second airflow channel 402, the air outlet 116 and the dust inlet 212, which are airflow inlets, wherein a portion of the airflow enters the accommodating chamber 210 through the air outlet 116, the air outlet 211, the channel cavity 214 and the communication hole 215, another portion of the airflow enters the accommodating chamber 210 from the dust inlet 114, the connection hole 115 and the dust inlet 212, and the airflow entering the accommodating chamber 210 carries the garbage objects in the accommodating chamber 210 from the dust outlet 213 to the dust box 311 of the base station 300 through the suction inlet 301.

If the filter member 216 filters the air flow flowing from the receiving chamber 210 to the passage chamber 214 through the communication hole 215 for a long period of time, dust and other debris may be attached, and the air flow flowing from the receiving chamber 210 to the passage chamber 214 may make it difficult to remove the debris on the filter member 216. Then, when the base station 300 sucks the garbage in the dust box 20, the airflow passing through the filter member 216 flows from the passage chamber 214 to the accommodating chamber 210 through the communication hole 215, so that the filter member 216 is automatically cleaned by the reverse airflow.

For the opening and closing assembly 500 to intermittently block the second airflow passage 402, the opening and closing assembly 500 may be used to intermittently block at least one of the dust suction port 114, the air discharge port 116, the dust inlet 212, the air outlet 211, and the dust outlet 213.

Based on the above, the first embodiment can be further explained as follows:

as shown in fig. 11, an opening and closing assembly 500 may be provided at the base station 300 for intermittently blocking the second airflow passage 402. The opening/closing unit 500 may be disposed on the base 320 and opposite to the dust suction port 114 (as shown in fig. 5) to intermittently close the dust suction port 114.

As shown in fig. 12 and 13, in particular, the base 320 may have a mounting cavity 323, and a side of the base 320 for carrying the cleaning apparatus 100 is opened with a mounting hole 324 communicating with the mounting cavity 323. For example, the second housing 322 is formed with a mounting cavity 323, and a mounting hole 324 is opened in a side wall of the second housing 322 for carrying the cleaning apparatus 100, and communicates with the mounting cavity 323. When the cleaning device 100 is carried on the base 320, the mounting hole 324 is opposite to the dust suction port 114 of the cleaning device 100.

The driving member 510 and the plugging member 520 may be disposed in the base 320, the driving member 510 and the plugging member 520 may be movably connected, and the driving member 510 is configured to drive the plugging member 520 to intermittently perform a telescopic motion, so that the plugging member 520 may intermittently extend out of the base 320 to plug the dust suction port 114. In particular, the blocking member 520 and the driving member 510 may be disposed within the mounting cavity 323. Further, the opening and closing assembly 500 may include a first transmission member 530 and a second transmission member 540.

The first transmission member 530 is movably disposed in the mounting cavity 323. The driving member 510 is connected to the first transmission member 530. The first transmission member 530 is connected to the blocking member 520. The driving member 510 may be used to drive the first transmission member 530 to move in a first direction, and the first transmission member 530 can drive the blocking member 520 to extend out of the mounting hole 324 or retract into the mounting hole 324 in a second direction different from the first direction during the movement. Wherein fig. 12 shows the blocking member 520 retracted into the mounting hole 324, and fig. 13 shows the blocking member 520 extended out of the mounting hole 324.

Thus, the blocking piece 520 extends out of the mounting hole 324 to block the dust suction port 114, and then intermittently blocks the second airflow channel 402, so that the pressure in the accommodating cavity 210 and the pressure in the channel cavity 214 can be changed, and then the garbage attached to the inside of the dust box 20 can be loosened and can be effectively sucked. Moreover, since the blocking member 520 intermittently blocks the dust suction opening 114 when the base station 300 sucks the garbage objects in the cleaning apparatus 100, a part of the air flow in the dust box 20 can flow into the accommodating chamber 210 through the air discharge opening 116, the passage chamber 214 and the communication hole 215, so that the filter element 216 in the communication hole 215 can be self-cleaned, the garbage objects on the filter element 216 are loosened during the pressure change process, and then the garbage objects can easily fall into the accommodating chamber 210, and finally enter the base station 300 along with the air flow through the dust outlet 213, thereby effectively improving the cleaning effect.

Through setting up the first transmission piece 530 of driving piece 510 drive and move to the first direction, and then drive shutoff piece 520 and stretch out mounting hole 324 or retract in mounting hole 324 in the second direction, the transmission structure that so sets up is convenient for realize effectively in the limited space of installation cavity 323 the intermittent type nature motion of shutoff piece 520, and transmission structure also can make driving piece 510 drive shutoff piece 520 and move more steadily and reliably moreover.

Optionally, the driving member 510 is connected to the second transmission member 540. The second transmission member 540 is connected to the first transmission member 530. The driving member 510 can drive the second transmission member 540 to rotate, and the second transmission member 540 drives the first transmission member 530 to move in the first direction through rotation.

Through setting up the rotation of second driving medium 540 and the removal of first driving medium 530 in the first direction, two kinds of different motion modes cooperate, can make transmission structure more stable, and then can ensure driving piece 510 and the transmission efficiency of shutoff piece 520.

As shown in fig. 12 and 13, the second transmission member 540 may rotate about a predetermined axis. The driving member 510 can be used to drive the second transmission member 540 to rotate around a predetermined axis, so as to drive the first transmission member 530 to move in a first direction. The driver 510 may have an output shaft, and the axis of the output shaft may be a preset axis. Alternatively, the second transmission member 540 may be disposed in a disc shape, the axis of the second transmission member 540 is a preset axis, and the axis of the driving member 510 may coincide with or substantially coincide with the axis of the second transmission member 540.

As shown in fig. 12 to 14, the first transmission member 530 may be disposed in a wedge shape. The first transmission member 530 is disposed opposite to the mounting hole 324. The first transmission piece 530 may have a wedge surface 531 inclined with respect to the first direction and forming a height step in the second direction. In other words, the wedge surface 531 is inclined at a certain angle to the first direction, and the wedge surface 531 forms a height difference in the second direction, similar to a slope having a certain slope. Specifically, the wedge surface 531 faces the mounting hole 324, being disposed opposite the mounting hole 324. The first transmission member 530 facing away from the wedge surface 531 or the bottom surface of the mounting hole 324 may slide in the first direction in the mounting cavity 323 in contact with the other side wall of the second housing 322 facing away from the mounting hole 324. The drive 510 is, for example, an electric motor.

The block piece 520 may abut the wedge surface 531. In the process that the driving element 510 drives the second transmission element 540 to rotate, the second transmission element 540 can drive the first transmission element 530 to move in the first direction, and the movement of the wedge surface 531 enables the contact position between the plugging member 520 and the wedge surface 531 to generate height change in the second direction, so that the plugging member 520 can extend out of the mounting hole 324 or retract into the mounting hole 324. Alternatively, the first transmission member 530 may be formed with weight-reducing grooves 532, and the weight-reducing grooves 532 may be formed from the wedge surface 531, so that the wedge surface 531 may be a discontinuous surface. The number of the weight-reduction grooves 532 may be one or more. Of course, in other implementations, wedge-shaped surface 531 may be a continuous complete surface.

Alternatively, the second transmission member 540 may be provided with an eccentric boss 541 deviated from a preset axis. In the present embodiment, "eccentric" of the eccentric post 541 may mean that its axis is parallel to or substantially parallel to but not coincident with the preset axis. Optionally, the axis of the eccentric convex column 541 is offset from the axis of the second transmission member 540 disposed in a disk shape. The first transmission member 530 may be provided with a sliding groove 533 spaced apart from the wedge surface 531. The eccentric protrusion 541 is slidably disposed in the sliding groove 533. When the driving member 510 drives the second transmission member 540 to rotate, the eccentric protrusion 541 can rotate around the predetermined axis to slide in the sliding groove 533, thereby driving the first transmission member 530 to move in the first direction.

Carry out the embedding cooperation through setting up spout 533 and eccentric projection 541, can make first driving medium 530 and second driving medium 540 connect the reliability higher, reduce the probability that first driving medium 530 and second driving medium 540 break away from each other, and then improve whole transmission structure's reliability, and the mode through rotary motion drives the removal of first driving medium 530 on the first direction, because the rotary mode is comparatively stable in stroke and structure, make both motion methods's cooperation transmission effect better. Optionally, the first direction and the second direction are perpendicular to each other. The extending direction of the sliding groove 533 may be perpendicular to both the first direction and the second direction. The first direction may, for example, coincide or substantially coincide with the direction of travel of the cleaning apparatus 100 on the base.

In some embodiments, the output shaft of the driving member 510 is disposed coaxially with the predetermined axis, and is connected to the second transmission member 540, so as to drive the second transmission member 540 to rotate around the predetermined axis. In other embodiments, the output shaft of the driving member 510 can be perpendicular to the predetermined axis, and can be driven by the engagement of two bevel gears (not shown in fig. 12 and 13), so as to rotate the second transmission member 540.

Of course, the second transmission member 540 may be disposed in a rod shape instead of a disk shape, and may have other shapes. For example, one end of the second transmission member 540 having a rod shape or other shapes is connected to the driving member 510, and the other end of the second transmission member 540 is provided with an eccentric cylinder 541, so that the eccentric cylinder 541 can rotate around the axis of the output shaft of the driving member 510. Alternatively, the second transmission member 540 may be a cam mechanism, and the first transmission member 530 is driven to move in the first direction by using the characteristics of the cam mechanism.

As shown in fig. 12, 13 and 15, optionally, the closure 520 may be restricted from moving in the second direction, i.e. the closure 520 is allowed to move in the second direction but not in the other direction. In this way, the reliability of the movement of the plugging member 520 can be improved, and the cleaning apparatus 100 can be plugged effectively. Specifically, the base 320 is provided with a first limiting portion 325 around the edge of the mounting hole 324. That is, the first limiting portion 325 surrounds at least a portion of the edge of the mounting hole 324, and further may surround the entire edge of the mounting hole 324. The first stopper 325 is extended toward the mounting cavity 323 in the second direction, or protrudes toward the mounting cavity 323 in the second direction. In other words, the space surrounded by the first position-limiting portion 325 is communicated with the mounting hole 324, the plugging member 520 can move in the space of the first position-limiting portion 325 and the mounting hole 324, and the first position-limiting portion 325 is used for regulating the moving path and direction of the plugging member 520.

Optionally, the shape of the first position-limiting portion 325 is matched with the shape of the plugging member 520, and the plugging member 520 is accommodated in the first position-limiting portion 325 to be limited to move in the second direction, that is, the plugging member 520 is accommodated in a space defined by the first position-limiting portion 325, and the space is communicated with the mounting hole 324. Thus, the movement of the plugging member 520 in the first limiting portion 325 and the mounting hole 324 can be more closely attached, the looseness of the plugging member 520 is reduced, and the deviation of the movement of the plugging member 520 in the second direction is reduced. Further, the block piece 520 may still be located in the first limiting portion 325 when being retracted into the mounting hole 324, so that the block piece 520 can be more effectively and stably limited to move in the second direction.

Optionally, the base 320 may be provided with a second stopper 326 in the mounting cavity 323. The second limiting portion 326 is used for limiting the first transmission member 530, so that the first transmission member 530 is limited to move in the first direction. As shown in fig. 15, specifically, the second limiting portion 326 may be disposed on a side wall of the second housing 322, where the mounting hole 324 is formed, for example, the second limiting portion 326 may include at least two side plates 3261, two of the side plates 3261 are disposed oppositely and fixed on a side wall of the base 320, and a length direction of the two side plates 3261 is the same as the first direction. The first transmission member 530 can slide between the two side plates 3261, and the length direction of the two side plates 3261 is the same as the first direction, so that the first transmission member 530 can be restricted from moving in the first direction. The width between the two side plates 3261 may be equal to or slightly greater than the width of the first transmission member 530, so that the first transmission member 530 can be accommodated between the two side plates 3261, and the side wall of the first transmission member 530 can be close to the two side plates 3261.

The first transmission piece 530 is limited by the second limiting part 326 to move in the first direction, so that the movement of the first transmission piece 530 is more stable, the blocking piece 520 can be more stably and effectively transmitted, errors of blocking actions of the blocking piece 520 caused by unstable movement of the first transmission piece 530 are reduced, the first limiting part 325 is arranged to limit the blocking piece 520 to move in the second direction, the movement of the blocking piece 520 can be further more stable, and the stability of the whole structure is enhanced.

As shown in fig. 12, 13 and 15, the base 320 may be provided with a third position-limiting portion 327 in the installation cavity 323. The third position-limiting portion 327 is used to limit a moving range of the eccentric convex cylinder 541, and the third position-limiting portion 327 is, for example, in an arc-shaped groove shape, that is, the shape of the third position-limiting portion 327 is a track of the eccentric convex cylinder 541 rotating around a preset axis, and may also be used to limit a stroke of the eccentric convex cylinder 541. Optionally, the base 320 may further be provided with a fixing column 328 coaxially disposed with the preset axis, and the second transmission member 540 is sleeved on the fixing column 328, and both are coaxially disposed. The second transmission piece 540 can rotate around the axis of the fixed column 328. Thus, the eccentric convex pillar 541 can rotate around the axis of the fixed pillar 328 at the third position-limiting portion 327, and the third position-limiting portion 327 can also reduce the transmission failure of the first transmission member 530 caused by the disengagement of the eccentric convex pillar 541, so that the structure is more stable.

During the movement of the first transmission member 530 in the first direction, the transmission block piece 520 moves in the second direction. In the process, a relative movement can occur between the first transmission piece 530 and the blocking piece 520, so that the blocking piece 520 can be moved in the second direction due to the difference in height of the wedge surface 531. In order to make the relative movement between the first transmission member 530 and the blocking member 520 more stable, the following structure may be further provided:

as shown in fig. 12 to 14, optionally, a side of the blocking piece 520 facing the first transmission piece 530 is provided with a limiting protrusion 521, that is, a side of the blocking piece 520 facing the wedge surface 531 is provided with a limiting protrusion 521. Correspondingly, the wedge 531 may be provided with a long-strip-shaped limiting hole 534. For example, the wedge surface 531 is provided with a stopper hole 534 in an oblique direction thereof. The limiting protrusion 521 is movably embedded in the limiting hole 534. When the first transmission member 530 moves in the first direction, the limiting protrusion 521 can move in the limiting hole 534 due to the relative movement between the blocking member 520 and the first transmission member 530. The limiting hole 534 can limit the limiting protrusion 521 to limit the track of the relative motion between the blocking piece 520 and the first transmission piece 530, and further standardize the track of the relative motion between the blocking piece 520 and the first transmission piece 530, so that the relative motion between the blocking piece 520 and the first transmission piece 530 is more stable, and the transmission fit between the blocking piece 520 and the first transmission piece 530 is more reliable.

Of course, the opening and closing member 500 of the first embodiment may have other structures than the above-listed exemplary structures as long as intermittent blocking of the second air flow path 402 can be achieved.

Based on the foregoing, the second embodiment can be further described as follows.

The opening and closing assembly 500 may be disposed at the base station 300 for intermittently blocking the first air flow passage 401. Optionally, the opening and closing assembly 500 may intermittently block at least one of the suction inlet 301 and the suction outlet 302. In the second embodiment, the opening and closing assembly 500 may have various structural forms, two of which are exemplified below:

a first exemplary structure: as shown in fig. 16, the driver 510 and the closure 520 may be movably connected. The driving member 510 is used for driving the blocking member 520 to intermittently perform a telescopic action, so that the blocking member 520 can intermittently extend to the suction inlet 301 or the suction outlet 302, and further, the first air flow channel 401 can be intermittently blocked.

In particular, the driving member 510 may be fixedly disposed inside the base station 300 and disposed adjacent to the suction inlet 301 or the suction outlet 302. For example, the driving member 510 may be disposed on a side wall of the base station 300, where the suction inlet 301 or the suction outlet 302 is opened, and the driving member 510 may drive the blocking member 520 to intermittently protrude to the suction inlet 301 or the suction outlet 302. The blocking piece 520 may block the suction inlet 301 or the suction outlet 302 when protruding to the suction inlet 301 or the suction outlet 302, and may open the suction inlet 301 or the suction outlet 302 after the retracting movement, thereby intermittently blocking the first air flow channel 401. For example, the driving member 510 may be movably connected to the blocking member 520 by a transmission member, for example, a retractable member, such as a retractable rod, etc., and the driving member 510, for example, a motor, and the blocking member 520 may be disposed in a plate shape. Of course, in order to complete the movement, corresponding parts, such as gears, slide rails and sliders, chains, belts, etc., may be matched, and may be set according to practical situations, so that the driving member 510 can drive the plugging member 520 to intermittently move back and forth in the corresponding direction, and further achieve the "telescopic" effect. Here, the telescoping movement may include a resilient telescoping movement, as well as a rigid back-and-forth movement. The rigid back and forth movement has a telescopic effect of extending into the suction inlet 301 or the suction outlet 302 and retracting out of the suction inlet 301 or the suction outlet 302. Corresponding tracks can also be arranged in the base station 300 for the blocking piece 520 to intermittently move back and forth so as to realize telescopic movement.

A second exemplary structure: as shown in fig. 17, the occluding member 520 is in a relaxed configuration. The expandable state means that the blocking member 520 can perform expansion and contraction movements, so that the area/volume thereof can be changed from large to small or from small to large. The occluding member 520 may be moved in a dilation or contraction motion, for example, to expand or close as in an "umbrella" or to expand or contract as in a "balloon".

The blocking piece 520 may be disposed within the first air flow channel 401, for example, may be disposed at the suction inlet 301 or the suction outlet 302. The driving member 510 may also be disposed in the first air flow channel 401, or may also be disposed at other positions of the base station 300. The driver 510 may be used to drive the blocking member 520 to intermittently expand or contract to intermittently block the first air flow channel 401.

When the blocking member 520 is in the relaxed state, its area/volume is large, and thus it can block the first air flow channel 401, for example, block the suction inlet 301 or the suction outlet 302. When the blocking piece 520 is in the contraction state, the area/volume of the blocking piece is small, so that the first air flow channel 401 can be in a smooth state compared with the relaxation state, and thus the blocking piece 520 performs intermittent relaxation and contraction, and the first air flow channel 401 can be intermittently blocked.

Of course, in addition to the two exemplary structures listed above, the second embodiment may also adopt the structure of the opening and closing assembly 500 described in the first embodiment, or may also adopt other structures as long as intermittent blocking of the first air flow channel 401 can be achieved.

Based on the foregoing, the third embodiment will be further described below.

In the embodiment of the cleaning apparatus, the opening and closing assembly 500 is disposed on the cleaning apparatus 100 for intermittently blocking the second air flow path 402. Specifically, the opening and closing assembly 500 may be provided to the apparatus body 10 and/or the dust box 20.

For example, an opening and closing assembly 500 may be provided to the dust box 20 for intermittently closing off the dust box passage so that the pressure within the dust box passage intermittently changes during the process of suctioning the trash objects within the dust box 20. The opening and closing assembly 500 may intermittently block the dust outlet 213, the dust inlet 212, or the air outlet 211, or may block the communication hole 215, the accommodating chamber 210, or the passage chamber 214.

Figure 18 illustrates an exemplary mating configuration of a partial cross-sectional configuration of the dirt box of figure 8 taken along section line a-a with the opening and closing assembly 500. As shown in fig. 18, the driving member 510 and the blocking member 520 may be disposed in the accommodating cavity 210, and the blocking member 520 is driven to perform a telescopic motion to intermittently block the dust outlet 213, so as to intermittently block the dust box passage, that is, intermittently block the second airflow passage 402.

Figure 19 illustrates another exemplary mating configuration of the partial cross-sectional configuration of the dirt box of figure 8 taken along section line a-a with the opening and closing assembly 500. As shown in fig. 19, the driving member 510 may be disposed in the accommodating cavity 210, or may be disposed outside the accommodating cavity 210. The blocking piece 520 may be disposed in the second airflow channel 402, such as the accommodating chamber 210 or the dust outlet 213. The driving member 510 may be used to drive the blocking member 520 to intermittently expand or contract so as to intermittently block the dust box passage, i.e. to intermittently block the second airflow passage 402.

For example, an opening and closing assembly 500 may be provided to the apparatus body 10 for intermittently blocking the body passage of the apparatus body 10 so that the pressure of the body passage intermittently changes during the process in which the dust box 20 is sucked with respect to the garbage objects. Specifically, the opening/closing unit 500 may intermittently close the dust suction port 114, the connection port 115, the air discharge port 116, or the like.

As for the structure of the opening and closing member 500 for intermittently blocking the passage of the subject, reference may be made to the exemplary structure shown in fig. 18 and 19, which will not be described herein.

In the third embodiment, as for the specific structure of the opening and closing member 500, reference is made to the specific description about the opening and closing member 500 in the first embodiment or the second embodiment. Of course, the third embodiment adopts the opening and closing assembly 500 of the first or second embodiment, and those skilled in the art can make some adaptations so that the opening and closing assembly 500 of the first or second embodiment can be applied to the third embodiment.

In summary, the intermittent movement can be in many forms, for example, the driving member 510 can drive the blocking member 520 to perform a telescopic movement so as to extend into the suction channel 400 or retract out of the suction channel 400, thereby intermittently blocking the suction channel 400. For example, the driving member 510 can drive the blocking member 520 to perform a relaxing motion, so as to be expanded in the suction channel 400 to block the suction channel 400, or contracted in the suction channel 400 to open the suction channel 400, thereby intermittently blocking the suction channel 400. Of course, the driving member 510 can drive the blocking member 520 to perform a rotational or translational movement, so that the blocking member 520 is intermittently located in the suction channel 400 through the rotational or translational switching position, thereby intermittently blocking the suction channel 400.

In this way, when the base station 300 sucks the garbage objects in the cleaning device 100, intermittent suction or pulse-like suction can be realized, so that pressure changes can be generated in the suction process, the garbage objects attached to the cleaning device 100 can be loosened, the suction effect is better, and related components in the cleaning device 100, such as the filter screen 216 and the like, can be cleaned.

Of course, the number of the opening and closing assemblies 500 may be plural, and the opening and closing assemblies may be respectively provided at the base station 300 and the opening of the cleaning device 100, which form the airflow passage, and are not expanded in detail. The respective opening/closing units 500 may perform the plugging operation simultaneously or may perform the plugging operation alternately.

Based on the foregoing description, an exemplary function two of the cleaning system embodiments of the present application, in which the base station 300 may clean the mop 134 of the cleaning device 100, may be implemented, may be further described as follows.

As shown in fig. 20, the base station 300 described in the base station embodiments of the present application may include a cleaning assembly 330, which may be disposed on the base 320, for example. The cleaning assembly 330 is used to clean the scrubbing mechanism of the cleaning device 100, as described in the following embodiments of the cleaning assembly of the present application.

As shown in fig. 20 and 21, a cleaning assembly 330 according to an embodiment of the cleaning assembly of the present application may include a guide tube 331 and a spray tube 332. The guide tube 331 is used to deliver the cleaning solution to the injection tube 332. The spray tube 332 is used to spray cleaning solution toward the wiper 134 of the cleaning device 100. The guide tube 331 may communicate with a clean water tank 312 provided in the base station main body 310, and the clean water tank 312 may supply a cleaning liquid to the guide tube 331.

Guide tube 331 is disposed on base 320. The base 320 is used to carry the cleaning device 100, which in turn may enable the cleaning device 100 to be positioned opposite the mop 134. The guide tube 331 and the spray tube 332 may be disposed in the washing bath 321, and the first pipeline t1 of the clean water tank 312 may extend to the inside of the washing bath 321 to communicate with the guide tube 331. The spray pipe 332 may spray a cleaning solution to the outside of the cleaning bath 321, and may further clean the cleaning apparatus 100. The sewage generated after the cleaning may flow into the cleaning tank 321, and may further flow into the sewage tank 313 through a pipe of the sewage tank 313. The spray pipe 332 may at least partially protrude out of the washing tank 321, so that the cleaning apparatus 100 may be better washed.

The connection structure of injection tube 332 and guide tube 331 can take a variety of forms, several of which are illustrated below.

The first structural form is as follows: as shown in fig. 22, the injection tube 332 is rotatably coupled to the guide tube 331 and communicates with the guide tube 331. That is, injection tube 332 may be rotated or swiveled relative to guide tube 331. Specifically, the spray tube 332 is capable of rotating relative to the guide tube 331 and the base 320 and spraying water toward the mop 134 of the cleaning device 100 to clean the mop 134 of the cleaning device 100.

The spray range formed by the rotation of the spray pipe 332 is circular or approximately circular, and correspondingly, the mop 134 can also be approximately circular, and the spray range of the spray pipe 332 can be larger than or equal to the area of the mop 134, so that the mop 134 can be better cleaned.

By arranging the injection pipe 332 to be rotatable relative to the guide pipe 331, the injection pipe 332 can perform rotary injection, and the injection area is increased. Different from the carousel formula injection, this embodiment is through the rotatory injection of pipy injection pipe 332, and volume and weight are less, can the using water wisely moreover, and the guide tube 331 is relatively fixed in addition, can improve the stability and the smoothness nature of supplying water for the injection process of injection pipe 332 is comparatively smooth, improves and sprays clean efficiency. Alternatively, the injection tube 332 and the guide tube 331 are cross-connected, and the injection tube 332 is rotated with respect to the guide tube 331 with the connection position as a rotation center. Specifically, the extension direction of the injection tube 332 may be the length direction thereof, and the connection position of the injection tube 332 and the guide tube 331 is located between both ends of the injection tube 332, so that the maximum rotation radius of the injection tube 332 is greater than or equal to half the length of the injection tube 332. Of course, the injection tube 332 may be provided in an "L" shape or an arc shape, and the connection position with the guide tube 331 may be located between both ends, or the injection tube 332 may be provided in an "X" shape, and the connection position with the guide tube 331 may be located at the intersection thereof. Thus, the spraying range of the spraying pipe 332 is wider, the mopping piece 134 can be better covered, and the cleaning effect of the mopping piece 134 is improved.

The injection tube 332 may be disposed in a flat shape. The rotation axis of the injection pipe 332 is perpendicular to the extending direction thereof and coincides with the thickness direction thereof. Thus, the injection tube 332 is flat, so that the connection between the guide tube 331 and the injection tube 332 is stable, and the rotation of the injection tube 332 is stable.

Guide tube 331 may also be flat. The connection position of the guide tube 331 and the injection tube 332 may be between both ends of the guide tube 331. Alternatively, the extending direction of the guide tube 331 may be the longitudinal direction thereof. Alternatively, guide tube 331 may be configured in an "L" or arc configuration, or jet tube 332 may be configured in an "X" configuration. Alternatively, the rotation axis of the injection tube 332 may be perpendicular to the thickness direction of the guide tube 331.

As shown in fig. 22, in order to make the rotational connection structure of both the injection tube 332 and the guide tube 331 more stable, the guide tube 331 may include two first tube segments 3311 and a first disk segment 3312. The two first tube segments 3311 are each fixedly connected to the first disk segment 3312 and each extend radially outward from the first disk segment 3312. Optionally, the two first tube segments 3311 extend in the same direction, and are disposed on two opposite sides of the first disk tube segment 3312. The number of first tube segments 3311 of guide tube 331 may be greater than two, each disposed on first disk segment 3312. Of course, by providing the number, extending direction and connecting position of the first tube segments 3311, the guide tube 331 can be provided in various shapes, such as "L" -shape, "X" -shape, etc.

The injection tube 332 may include two second tube segments 3321 and a second disk segment 3322, wherein the two second tube segments 3321 are fixedly connected to the second disk segment 3322 and extend radially outward from the second disk segment 3322. Optionally, the two second tube segments 3321 extend in the same direction and are oppositely arranged on two sides of the second disc tube segment 3322. Of course, the number of the second tube sections 3321 of the guide tube 331 may be more than two, each being disposed on the second disk section 3322. Of course, by setting the number, extending direction and connecting position of the second pipe sections 3321, the injection pipe 332 can be provided in various shapes, such as "L" shape, "X" shape, etc.

Wherein the first disk segment 3312 and the second disk segment 3322 are coaxially disposed and rotatably coupled. The injection pipe 332 and the communication pipe are connected and communicated through the first disk pipe section 3312 and the second disk pipe section 3322, so that the guide pipe 331 is more stable in supporting the injection pipe 332, the rotatable connection between the two is more stable, the area of the disk pipe section is larger, the communication structure between the two is favorably arranged, and the reliability of the structure is improved. Specifically, the motor may be disposed on a side of the guide tube 331 away from the injection tube 332, and an output shaft thereof may extend into the first disk section 3312 and be connected to the second disk section 3322 to drive the second disk section 3322 to rotate. Alternatively, the motor may be disposed within the first spool piece 3312 of the guide tube 331.

As shown in fig. 23, the guide tube 331 may be provided with a first conveying channel 3310 extending along the extending direction thereof. The guide tube 331 may be formed with a liquid inlet hole 3313 communicating with the first transporting passage 3310. Specifically, the liquid inlet 3313 may be disposed at least in one of the first pipe segments 3311, for example, at one end of the one of the first pipe segments 3311. The liquid supply mechanism 316 can be connected to the liquid inlet 3313 via a first pipe t1, so that the liquid inlet 3313 can be connected to the clean water tank 312.

The injection pipe 332 may be opened with a second feeding passage 3320 extending along the extending direction thereof. The first transporting passage 3310 communicates with the second transporting passage 3320. One side of the injection tube 332, which is far away from the guide tube 331, is opened with a spraying hole 3323 communicated with the second conveying channel 3320. The spray holes 3323 are used to spray a cleaning solution to the wiper 134 of the cleaning apparatus 100. Alternatively, the number of the injection holes 3323 is plural, and the plural injection holes 3323 are provided at intervals along the extending direction of the injection tube 332. Specifically, the two second pipe sections 3321 and/or the second disk pipe section 3322 may be provided with spray holes 3323. The plurality of spray holes 3323 can form a water curtain while spraying, and effectively improve the spraying range and the spraying efficiency during the rotary spraying process.

The cleaning assembly 330 can also rub the wiping member 134 when spraying the cleaning solution to the wiping member 134 for cleaning, thereby improving the cleaning effect. Specifically, the cleaning assembly 330 may include a wiper 333. The scraping member 333 is adapted to rotate with the injection pipe 332, and further rubs the scraping member 134 during the rotation, and is adapted to spray a cleaning liquid, so as to clean the scraping member 134 more effectively.

The scraping member 333 may be disposed at a side of the injection pipe 332 facing away from the guide pipe 331, and may contact and scrape the scraping member 134 of the cleaning apparatus 100, so as to scrape the scraping member 134 of the cleaning apparatus 100 while the injection pipe 332 sprays the cleaning solution to the scraping member 134 of the cleaning apparatus 100 through the spraying hole 3323. The scraping element 333 may be at least partially exposed from the cleaning groove 321, so as to better contact the scraping element 134.

When the rotary spraying is performed through the rotation of the spraying pipe 332, the scraping piece 333 is driven to scrape the scraping piece 134, so that the spraying synchronization can be realized, and the cleaning effect can be effectively improved.

The scrapers 333 may be spaced apart from the spray holes 3323. Of course, the scrapers 333 may also be provided on the outer circumference of the injection holes 3323. For example, the scraper 333 is annularly provided around the outer circumference of the injection hole 3323. By arranging the scraping member 333 around the outer circumference of the injection hole 3323, the scraping member 333 rubs the scraping member 134 at a position where the impact force of the injection from the injection hole 3323 is high, thereby further improving the cleaning effect.

Alternatively, the number of the scrapers 333 is the same as the number of the injection holes 3323. The number of the injection holes 3323 is plural, the number of the scrapers 333 is plural, and one circle of the scrapers 333 is provided on the outer circumference of each injection hole 3323. If the scraping member 333 is not annularly provided, one ring of the scraping member 333 may include a plurality of scraping members 333. If the scraping member 333 is annularly provided, one circle of the scraping member 333 may be one scraping member 333, or a plurality of scraping members 333. Of course, the plurality of scrapers 333 and the plurality of injection holes 3323 may be staggered.

Optionally, the scraping member 333 is an elastic scraping member 333, and for example, the material thereof may include soft elastic material such as rubber, silicon gel, and the like. Alternatively, the scraper 333 is a brush scraper 333, for example, comprising bristles fixed to the spray tube 332.

Optionally, the guide tube 331 may be opened with an air inlet 3314. The air inlets 3314 are spaced apart from the liquid inlet 3313. The air inlets 3314 may be formed in another first tube portion 3311, specifically, in an end of the first tube portion 3311 away from the first disk portion 3312. The air inlets 3314 may communicate with the first delivering passage 3310, and the air inlets 3314 are used for guiding the dry air to the first delivering passage 3310. The air supply mechanism 317 may communicate with the air inlet holes 3314 through the second pipe t 2. The spray holes 3323 are used to spray dry gas toward the wiper 134 of the cleaning apparatus 100.

In order to realize the alternate output of the liquid supply mechanism 316 and the gas supply mechanism 317, in addition to the aforementioned switching mechanism 319, the following can be realized: the liquid supply mechanism 316 and the gas supply mechanism 317 can be switched by corresponding control circuits of the base station 300. For example, when the cleaning operation is performed, the liquid supply mechanism 316 is operated, the gas supply mechanism 317 is not operated, and the cleaning operation can be performed through the guide tube 331 and the injection tube 332. When the drying operation is performed after the cleaning operation, the air supply mechanism 317 is operated and the liquid supply mechanism 316 is not operated. The air inlet holes 3314 are formed in the guide tube 331 and communicated with the first conveying passage 3310, so that the rotary water-jet cleaning and the air-jet drying are realized through the guide tube 331 and the jet tube 332, the cleaning efficiency can be greatly improved, and the device is simple in structure, stable and reliable.

The second structural form is substantially the same as the first structural form, and is mainly different from the first structural form in that: the first structure realizes rotary spraying by rotation, and the second structure realizes spraying and cleaning by reciprocating movement along a preset direction. The differences between the second embodiment and the first embodiment are described below, and the same reference is made to the description of the first embodiment.

With the second configuration, as shown in FIG. 24, the cleaning assembly 330 is disposed on the base 320. At least a portion of the cleaning assembly 330 is capable of reciprocating in a predetermined direction relative to the base 320 and is configured to contact the mop 134 of the cleaning device 100 and spray a cleaning fluid onto the mop 134 of the cleaning device 100 to clean the mop 134 of the cleaning device 100.

At least a portion of the cleaning assembly 330 is capable of reciprocating in a predetermined direction relative to the base 320, such that a corresponding cleaning range is formed in the predetermined direction. Accordingly, the mop 134 may also be correspondingly shaped. By arranging that at least part of the cleaning assembly 330 can move back and forth along the preset direction, a larger cleaning range can be formed conveniently, and further, the cleaning of the mopping piece 134 with an irregular shape can be satisfied, for example, the edge of the mopping piece 134 is not regular, if the cleaning range formed by the rotation mode can not satisfy the cleaning of the mopping piece 134, and the cleaning range formed by the back and forth movement along the preset direction extends to the farthest edge position of the mopping piece 134, so that the cleaning of the mopping piece 134 can be satisfied, and thus the cleaning assembly can be adapted to the irregular-shaped mopping piece 134. Moreover, by reciprocating at least a portion of the cleaning assembly 330 in a predetermined direction, the wiping member 134 can be ejected and rubbed back and forth in the predetermined direction, and the cleaning efficiency can be greatly improved.

Specifically, at least the spray tube 332 is capable of reciprocating in a predetermined direction relative to the base 320 and spraying cleaning fluid toward the wiper 134 of the cleaning device 100. In this way, the guide tube 331 guides the cleaning liquid to the injection tube 332 by the mutual engagement of the injection tube 332 and the guide tube 331, and at least the injection tube 332 reciprocates in a predetermined direction, so that structural stability can be improved, and a stable cleaning range can be formed by the reciprocation of the injection tube 332. Further, the preset direction is not overlapped with or crossed with the extending direction of the injection pipe 332, so that the cleaning range formed by the reciprocating movement of the injection pipe 332 is large. Alternatively, the extending direction of the injection pipe 332 may be the length direction thereof, and the preset direction may be perpendicular to the extending direction of the injection pipe 332, so that a rectangular cleaning range with a reciprocating distance and two sides of the length of the injection pipe 332 may be formed, and further, the requirement for the special-shaped mopping piece 134, such as the semicircular, elliptical or other-shaped mopping piece 134, may be better satisfied.

Injection tube 332 may reciprocate in a predetermined direction relative to guide tube 331 and base 320, or injection tube 332 and guide tube 331 may reciprocate together in a predetermined direction relative to base 320.

For the injection tube 332 to reciprocate in a predetermined direction with respect to the guide tube 331 and the base 320, the guide tube 331 may be fixedly provided to the base 320. The injection tube 332 is movably connected to the injection tube 332. The injection tube 332 is capable of reciprocating in a predetermined direction with respect to the guide tube 331, and further, is capable of reciprocating in a predetermined direction with respect to the guide tube 331 and the base 320. During movement of injection tube 332 relative to guide tube 331, the two may remain in communication. The washing groove 321 of the base 320 may be sized to allow the injection tube 332 to reciprocate in a predetermined direction.

For example, both injection tube 332 and guide tube 331 may be connected in a substantially "cross-like configuration, although other shapes or connection configurations are possible.

As shown in fig. 24 and 25, for example, the base 320 may be provided with a first slide rail 329 extending along a preset direction in the cleaning tank 321, the spray pipe 332 may be provided with a first slide block 3324 matching with the first slide rail 329, the first slide block 3324 may be movably provided on the first slide rail 329, and the spray pipe 332 may be capable of moving along the preset direction relative to the base 320 through the cooperation of the first slide block 3324 and the first slide rail 329. Guide tube 331 may be fixed to base 320 and, in turn, injection tube 332 may be movable relative to guide tube 331.

Further, the injection tube 332 is movably connected to the guide tube 331, for example, the guide tube 331 may be provided with a second slide rail 3315 extending along a predetermined direction, the injection tube 332 may be further provided with a second slide block 3325 matching with the second slide rail 3315, the second slide block 3325 may be movably disposed on the second slide rail 3315, and the injection tube 332 is moved along the predetermined direction relative to the base 320 and the guide tube 331 by the cooperation of the first slide block 3324 and the first slide rail 329 and the cooperation of the second slide block 3325 and the second slide rail 3315.

For example, the number of the first slide rails 329 may be two, and the first slide rails are respectively disposed at two ends of the injection pipe 332, and the injection pipe 332 is respectively provided with the corresponding first sliders 3324 at the two ends thereof. The extension direction of the guide tube 331 may be identical to the preset direction, and the extension direction of the injection tube 332 may be perpendicular to the preset direction.

Wherein the guiding tube 331 can be communicated with the spraying tube 332 through at least one flexible tube. The length of the hose can match the sliding travel of the jet tube 332 so that the jet tube 332 can remain connected to the guide tube 331 during sliding.

In other embodiments, as shown in fig. 26, guide tube 331 can be a flexible tube, and/or a flexible rigid tube. The rigid telescopic tube is for example a rigid telescopic tube. The injection tube 332 is connected to the guide tube 331 and communicates with the guide tube. During the reciprocating movement of the injection tube 332 in the preset direction, the guide tube 331 makes a telescopic movement therewith to accommodate the reciprocating movement of the injection tube 332. Similarly, injection tube 332 may drag guide tube 331, and guide tube 331 generates a telescoping motion during the dragging. The length of guide tube 331 is sufficient to allow the maximum travel of injection tube 332. For example, one end of the guide tube 331 is connected to a corresponding tube of the clean water tank 312, for example, the first tube t1, the other end or a middle position of the guide tube 331 may be connected to the injection tube 332, and during the movement of the injection tube 332, the connection position of the guide tube 331 and the injection tube 332 may be relatively extended and contracted with respect to one end of the guide tube 331. Further, the other end of the guide tube 331 may be connected to a corresponding tube of the gas supply mechanism 317, for example, a second tube t2, the injection tube 332 is connected between the two ends of the guide tube 331, and the connection position of the guide tube 331 and the injection tube 332 may be telescopically moved with respect to the two ends of the guide tube 331.

Of course, the movable connection between the injection tube 332 and the guide tube 331 can be other common sliding structures besides the matching structure of the sliding block and the sliding rail.

To the extent that injection tube 332 and guide tube 331 can move back and forth together in a predetermined direction relative to base 320, injection tube 332 and guide tube 331 are relatively fixed, e.g., fixedly connected, and can move back and forth together in a predetermined direction relative to base 320.

As shown in fig. 27, the base 320 may be provided with a first slide rail 329 extending in a predetermined direction in the cleaning tank 321, for example. The injection pipe 332 may be provided with a first slider 3324, respectively. The first sliding block 3324 is movably disposed on the first sliding rail 329. The injection pipe 332 is movable in a predetermined direction with respect to the base 320 by the cooperation of the first slider 3324 and the first slide rail 329. Injection tube 332 may move guide tube 331 during the movement. Optionally, the guiding tube 331 may also be provided with a third sliding block 3316, the base 320 may be correspondingly provided with a third sliding rail 3200 matched with the third sliding block 3316 of the guiding tube 331 in the cleaning tank 321, and the guiding tube 331 may move relative to the base 320 through the matching of the third sliding block 3316 and the third sliding rail 3200. The guide tube 331 and the injection tube 332 may be connected and communicated with each other, or may be communicated with each other through a hose. Certainly, the base 320 may be provided with a receiving groove (not shown), the guide tube 331 is movably embedded in the receiving groove, and the guide tube 331 may drive the injection tube 332 to move in the predetermined direction when sliding in the receiving groove, or the injection tube 332 may drive the guide tube 331 to slide in the receiving groove when reciprocating in the predetermined direction. Of course, the guide tube 331 and the base 320 may be movably connected through a sliding block, a sliding rail, and the like, and the injection tube 332 is driven to move in the moving process of the guide tube 331.

In addition to the mating structure of the slider and the slide rail, the movable connection between the injection tube 332 and/or the guide tube 331 and the base 320 may also be other common sliding mating structures. In the second structural form, the first structural form may be referred to with respect to the shape structures, connection relationships, and the like of the scraper 333, the injection tube 332, and the guide tube 331, and details thereof will not be repeated.

In addition, for the above two structural forms, the air inlet holes 3314 may not be opened in the guide tube 331. The purge assembly 330 may further include a gas conduit (not shown) in communication with the injection tube 332 for delivering the dry gas to the injection tube 332. The gas-guiding tube may be independent from the guiding tube 331, and correspondingly supply the cleaning solution and the drying gas to the injection tube 332.

While the foregoing description has shown some embodiments of the dirt tray 20 in the present cleaning device embodiments, the following present cleaning device embodiments may also illustratively show other embodiments.

As shown in fig. 28, the dust box 20 described in the embodiments of the dust box of the present application may include: a dust box body 21 and an electrostatic assembly 22.

The dust box main body 21 may be provided with a dust inlet 212, an accommodating space 200 and an air outlet 211, and the dust inlet 212 and the air outlet 211 are respectively communicated with the accommodating space 200. The electrostatic assembly 22 is disposed in the accommodating space 200. The electrostatic component 22 is located between the dust inlet 212 and the air outlet 211. That is, the electrostatic assembly 22 may separate the accommodating space 200, so that the dust inlet 212 and the air outlet 211 may be respectively communicated with portions of the accommodating space 200 located at two sides of the electrostatic assembly 22.

Optionally, the dust box 20 may include a first filter 23 and a second filter 24. The first filter 23 is disposed at the dust inlet 212 or between the electrostatic assembly 22 and the dust inlet 212. So, can carry out preliminary absorption to the great rubbish object or the granule that the air current carried to subsequent static subassembly 22's further adsorption improves adsorption efficiency. The first filter 23 is, for example, a HEPA filter (filter). The second filter 24 is disposed at the outlet 211, or between the electrostatic assembly 22 and the outlet 211. Through setting up second and filtering piece 24 between air outlet 211 or air outlet 211 and static subassembly 22, can minimize the air current and carry the dust or the rubbish object of missing and flow out for the rubbish object is better to be kept in accommodation space 200. Alternatively, the second filter 24 may be a sponge. The electrostatic assembly 22 may be disposed between a first filter member 23 and a second filter member 24.

As shown in fig. 28 and 29, the electrostatic assembly 22 may be provided with a through hole 220. The through hole 220 may be used to guide the airflow in the accommodating space 200 from the side of the electrostatic component 22 close to the dust inlet 212 to the side of the electrostatic component 22 close to the air outlet 211. In the present embodiment, the side of the electrostatic component 22 close to the dust inlet 212 may refer to a side close to the dust inlet 212 on the structure, and may also refer to a side close to the dust inlet 212 in the airflow flowing direction. Similarly, the side of the electrostatic component 22 close to the air outlet 211 may refer to a side of the structure close to the air outlet 211, or may refer to a side close to the air outlet 211 in the airflow flowing direction. The electrostatic assembly 22 may be used to conduct adsorptive deposition of dust carried by the airflow after passing through the through hole 220 by the static electricity attached thereto.

After entering the accommodating space 200 through the dust inlet 212, the airflow enters the side of the electrostatic component 22 close to the air outlet 211 from the side of the electrostatic component 22 close to the dust inlet 212 through the through hole 220 of the electrostatic component 22, and then flows out through the outlet.

During operation of the cleaning device 100, suction is generated in the receiving space 200 such that debris objects enter the receiving space 200 with the airflow, which enters the receiving space 200 may impinge on the electrostatic assembly 22, the speed is further reduced, which is beneficial to the sedimentation of the garbage and dust, when the airflow passes through the through hole 220, the speed is increased, after the airflow enters from the side close to the dust inlet 212 to the side close to the air outlet 211, since the buffer effect is generated again from the small channel into the larger space, buffer regions are formed at both sides after passing through the through-hole 220, thus, the electrostatic assembly 22 further adsorbs smaller dust carried by the airflow passing through the through hole 220 by the static electricity attached thereto, so that the dust can be more effectively adsorbed, the dust collection efficiency can be improved, thereby more greatly causing dust to remain in the accommodating space 200 and eventually improving the cleaning efficiency of the cleaning apparatus 100.

In addition, the second filter element 24 is arranged between the air outlet 211 or the electrostatic component 22 and the air outlet 211, and can optimize the airflow of the accommodating space 200, so that the airflow is uniform, the buffering and decelerating effect of the airflow flowing through the through hole 220 is more obvious, the influence of the extreme speed of the air outlet 211 on the buffering effect is reduced, and the working efficiency of the electrostatic component 22 can be improved.

Optionally. The number of the through holes 220 is plural, and the plural through holes 220 are spaced apart from each other in the electrostatic module 22. This may allow the electrostatic assembly 22 to be substantially reticulated. For example, two adjacent through holes 220 are spaced 1-5mm apart.

As shown in fig. 29, specifically, the electrostatic module 22 may include a substrate 221 and an electrostatic attachment 222. The substrate 221 is disposed in the accommodating space 200 and divides the accommodating space 200. The through hole 220 is opened in the substrate 221. The electrostatic attachment 222 is connected to a side of the substrate 221 near the air outlet 211. The electrostatic attachment 222 is used for performing adsorption deposition on dust carried by the airflow passing through the through hole 220 by static electricity attached thereto. The structure can be more reliable by dividing the accommodating space 200 by the substrate 221, and the electrostatic adhesive member 222 is connected to the substrate 221, so that the dust adsorption efficiency can be improved.

Optionally, the substrate 221 is a metal substrate for electrical connection with the electrostatic generator 25. The electrostatic generator 25 may be disposed on the dust box body 21 or outside the dust box body 21. The electrostatic generator 25 may be connected to a corresponding power source of the cleaning device 100. Of course, the electrostatic generator 25 may be a component of the electrostatic assembly 22. The electrostatic generator 25 is for generating charges on the substrate 221, which can be attached to the electrostatic attachment 222. Thus, the charges attached to the electrostatic attachment member 222 can form a stable adsorption effect. The charge is, for example, negative ions.

Alternatively, the electrostatic attachment 222 may include a pile (not shown). The fluff piece is disposed on a side of the substrate 221 near the air outlet 211. That is, a fluff piece may be implanted on a side of the base 221 near the air outlet 211. The fluff is used to attach electric charges generated on the substrate 221.

Optionally, an insulating layer 223 is disposed on a side of the substrate 221 near the dust inlet 212. An insulating layer 223 is disposed on a side of the substrate 221 near the dust inlet 212 to enable dust to be better electrostatically adsorbed after passing through the through-hole 220. In addition, by providing the insulating layer 223, two or more electrostatic modules 22 can be provided in the accommodating space 200. The dust strikes in the one side that base plate 221 is close to into dirt mouth 212 after entering into accommodation space 200 from entering dirt mouth 212, and speed slows down, gets into great space once more behind through-hole 220 and produces the cushioning effect, and then makes the dust effectively adsorbed by static, can make less dust also adsorbed, improves the adsorption efficiency of dust.

Alternatively, the number of electrostatic components 22 may be at least two. The two electrostatic assemblies 22 are disposed in the accommodating space 200 at intervals, and the through holes 220 of any two adjacent electrostatic assemblies 22 are disposed in a staggered manner. For example, the axes of the through-holes 220 of any two adjacent electrostatic assemblies 22 do not coincide. Through setting up two at least static subassemblies 22, and the through-hole 220 dislocation set of two adjacent static subassemblies 22 for the air current can be adsorbed many times through the in-process dust that advances dust mouth 212 entering finally and flow out through air outlet 211, improves adsorption efficiency, makes the air current that finally flows out clean, improves environmental protection efficiency and clean effect.

In order to further enable the air flow to generate a more effective buffering effect after passing through the through hole 220, a protrusion 2211 may be formed on one side of the substrate 221 near the air outlet 211. The through hole 220 is opened in the protrusion 2211 to communicate with or penetrate through two opposite sides of the substrate 221. That is, the protrusion 2211 may be protruded on a side of the substrate 221 near the air outlet 211. Of course, further, the protrusion 2211 may be protruded on both sides of the substrate 221. The through hole 220 may penetrate the protrusion 2211, communicating both sides of the substrate 221. The through-hole 220 is actually a channel with a certain length. In this way, the through hole 220 may be regarded as a small tunnel region with respect to a partial space of the accommodating space 200 on the side of the substrate 221 near the outlet, and the partial space of the accommodating space 200 may be regarded as a large tunnel region. In this embodiment, the electrostatic attachment 222 is disposed on a side of the substrate 221 near the air outlet 211, and may include an outer periphery extending to the protrusion 2211.

The air current passes through the through-hole 220 of bellying 2211, then has certain flow distance at through-hole 220, and speed is very fast, when entering into the partial space that base plate 221 is close to air outlet 211 one side, has got into great space, and speed slows down, and then further produce more effective buffering effect, and then the air current can flow toward the both sides region of through-hole 220, so the static that is located the through-hole 220 periphery adheres to piece 222 and can pass through electrostatic adsorption dust better, reach good dust removal effect.

As shown in fig. 29, alternatively, the diameter of the through-hole 220 is gradually reduced in a direction from a side of the substrate 221 near the dust inlet 212 to a side of the substrate 221 near the air outlet 211. That is, the diameter of the through-hole 220 gradually decreases in the flow direction of the air flow within the through-hole 220. So, can make the speed that the air current flows in through-hole 220 crescent, and then make the air current produce more effective cushioning effect after flowing to great space through-hole 220, the air current can drive the dust and flow towards the both sides of through-hole 220, also at least partial air current is attached to piece 222 backward flow towards static, and then can be adsorbed by static and attach to piece 222.

Optionally, the area where the protrusion 2211 and the substrate 221 connect the protrusion 2211 is rounded off. In this way, the projection 2211 is shaped like a hill, and can better adsorb the slow dust.

As shown in fig. 30, the receiving space 200 may include a receiving chamber 210 and a passage chamber 214, and the passage chamber 214 and the receiving chamber 210 communicate through a communication hole 215. The communication hole 215 is located between the dust inlet 212 and the air outlet 211. That is, the main body 21 of the dust box is formed with an accommodating chamber 210 and a passage chamber 214 which are arranged at intervals, as shown in fig. 9 and 10. The receiving chamber 210 and the passage chamber 214 communicate through the communication hole 215, and the receiving space 200 may be formed. Of course, fig. 9 and 10 show only one exemplary structure of the dust box main body 21, and the positions and the like of the dust inlet 212, the air outlet 211, and the communication hole 215, and the housing chamber 210 and the passage chamber 214 may be adjusted as needed. Alternatively, the electrostatic assembly 22 may be disposed in the channel cavity 214 between the air outlet 211 and the communication hole 215, and necessarily between the dust inlet 212 and the air outlet 211. Generally, the accommodating cavity 210 is used for accommodating garbage objects, but some particle dust enters the channel cavity 214, and the electrostatic component 22 can further adsorb the garbage objects such as dust with smaller particles, so as to improve the cleaning effect, so that the airflow flowing out from the air outlet 211 is cleaner and more environment-friendly.

Optionally, a screen member 216 is provided within the communication hole 215. Alternatively, the first filter 23 is disposed in the communication hole 215, in other words, the filter element 216 can be used as the first filter 23, so that most of the garbage objects are intercepted in the accommodating chamber 210, and the electrostatic assembly 22 in the passage chamber 214 can further adsorb the garbage objects such as small particles of dust, thereby improving the cleaning efficiency through multiple filtering and adsorption.

Of course, the electrostatic assembly 22 may also be disposed in the accommodating chamber 210 between the dust inlet 212 and the communication hole 215. Alternatively, the receiving chamber 210 and the passage chamber 214 may each be provided with the electrostatic assembly 22.

In this embodiment, the through hole 220 is formed on the electrostatic component 22, so that the airflow enters the accommodating space 200 through the through hole 220 and is located in a part of the space of the electrostatic component 22 close to the air outlet 211 to generate a buffering effect, the speed is reduced, the electrostatic component 22 can adsorb dust carried by the airflow passing through the through hole 220 through the attached static electricity, and the dust collection and cleaning efficiency is improved.
