In the cleaning robot of this disclosure, rationally configured the dust and retrieved the structure that supplies water with the water tank, can guarantee the volume of water tank subassembly from this, also guaranteed simultaneously that cleaning robot returns the butt joint of station back and basic station dust absorption passageway for the dust in the dust collection component is retrieved to basic station accessible air duct system.

For ease of understanding, the specific structure of the cleaning robot of the present disclosure and the operation principle thereof will be described in detail with reference to fig. 1 to 7 in conjunction with one embodiment.

As shown in fig. 1 and 2, the present disclosure provides a cleaning robot including a body 10 and a water tank assembly 20.

The body 10 serves as a carrier and is configured to mount various functional elements required by the cleaning robot, such as a cleaning cloth disc, a rolling brush, a motor, a dust box, a fan, and the like, which are well known to those skilled in the art, according to the specific function and structure of the cleaning robot. It should be noted that fig. 1 and 2 of the present disclosure only show a partial structure of the body 10 of the cleaning robot, and the rest is substantially the same as the body 10 of the existing cleaning robot, which can be completely implemented by those skilled in the art based on the prior art, and thus, the description thereof is omitted here. In one embodiment of the present disclosure, the functional elements include at least a dust collection assembly and a water tank assembly 20, and may further include a striking plate assembly 30 and a wiping cloth plate 40.

As shown in fig. 1 and 2, generally, when the advancing direction of the cleaning robot is defined as the front, the striking plate assembly 30 is disposed in front of the machine body 10, and the water tank assembly 20 is disposed in the rear of the machine body 10, i.e., the water tank assembly 20 is located at a side facing away from the advancing direction of the cleaning robot, so that the arrangement of the striking plate assembly 30 and other functional elements is not affected.

As shown in fig. 2, the machine body 10 includes a base plate 11 at a lower end and a cover 12 at an upper end, the mounting groove 13 is formed by sandwiching the base plate 11 and the cover 12, and when the water tank assembly 20 is mounted in the mounting groove 13, the water tank assembly 20 is carried on the base plate 11.

In this way, the weight of the water tank assembly 20 is borne by the chassis 11 of the machine body 10, and the stability of the water tank assembly 20 after installation can be improved.

Further, with continued reference to fig. 2, when the water tank assembly 20 is mounted to the machine body 10, no gap is generated between the machine body 10 and the water tank assembly 20 because the water tank assembly 20 has an outer contour adapted to the machine body 10.

Specifically, as shown in fig. 2, in the present embodiment, the water tank assembly 20 of the present disclosure includes a tank body 21, a groove 211 is disposed in a middle region of the tank body 21, and a protrusion 14 is disposed on the machine body 10 corresponding to the groove 211 of the tank body 21.

When assembling, the protrusion 14 on the machine body 10 is snapped into the groove 211 of the box body 21, which can limit the movement of the box body 21 relative to the machine body 10 along the circumferential direction thereof, so as to achieve the rapid pre-positioning of the machine body 10 and the box body 21. In addition, the existence of arch 14 and recess 211 also can remind the assembly relative position between user's organism 10 and box 21 to prevent the user from upside down the assembly mistake that the installation arouses, form a fool-proof design through the arch 14 and the recess 211 of looks adaptation among this disclosure promptly, make the user accomplish both's equipment fast, improve user's use experience.

As described above, the water tank assembly 20 and the machine body 10 are detachably connected so that the user can add water into the tank 21, and in the present embodiment, the machine body 10 and the water tank assembly 20 of the present disclosure are detachably connected by a snap assembly.

Specifically, as shown in fig. 2, 4 to 6, a snap assembly 22 is disposed on the box 21, the snap assembly 22 is disposed on the groove 211, and correspondingly, a fixing groove (not shown) adapted to the snap assembly 22 is disposed on the machine body 10.

In detail, the catch assembly 22 includes a first catch 221 and a second catch 222 arranged along the extending direction of the water tank assembly 20, and the distance between the first catch 221 and the second catch 222 is 10mm to 200mm, i.e., the range of L1 in fig. 6 is 10mm to 200mm. So set up, on the one hand can avoid because two buckle intervals undersize, cause the problem of the easy skew of water tank set spare 20 atress back, on the other hand also can avoid because two buckle intervals are too big, cause the recess 211 width great, occupy too many water tank spaces, make the problem of water tank capacity reduction.

As shown in fig. 5, in an embodiment of the present disclosure, the latch assembly 22 includes a pressing plate 223, a spring 224, a limiting plate 225, and a cylinder disposed on the pressing plate 223 and extending toward the machine body 10, wherein the spring 224 is connected to the box 21 at the bottom and connected to the pressing plate 223 at the top; and the pressing plate 223 forms a depressed pressing area at the outer side position of the groove 211 for the user to press; the limiting plate 225 is arranged above the pressing plate 223 and is fixedly connected with the box body 21, and a through hole for the column body on the pressing plate 223 to extend out is arranged above the limiting plate 225; the cylinders are disposed on the pressing plate 223 and extend toward the machine body 10, and the two cylinders in fig. 5 are the first fastener 221 and the second fastener 222.

Due to the limiting function of the limiting plate 225, when the user does not press the pressing area of the pressing plate 223, the spring 224 abuts the pressing plate 223 against the limiting plate 225, so that the cylinder is clamped into the fixing groove of the body, thereby installing the water tank assembly 20 on the body 10.

On the contrary, when the user presses the pressing area of the pressing plate 223, the pressing plate 223 moves downward to drive the two columns to leave the fixing groove, so that the relative constraint relationship between the machine body 10 and the water tank assembly 20 is eliminated, and at this time, the user can take the water tank assembly 20 out of the mounting groove 13 of the machine body 10.

It should be noted that, according to this disclosure, the buckle subassembly and the fixed recess of looks adaptation with it can reverse the setting, and the buckle subassembly sets up on the organism promptly, and the fixed slot is then seted up at the box of water tank set spare.

With continued reference to fig. 2, the chassis 11 is provided with a notch 15 at a position corresponding to the pressing area, and the notch 15 is configured to expose a portion of the surface of the water tank assembly 20 from the chassis 11, so that a user can press the water tank assembly 20 from both the upper and lower directions, and can easily pull the water tank assembly 20 out of the mounting groove 13.

To facilitate the installation of the water tank assembly 20, in one embodiment of the present disclosure, a guide surface (not shown) for pressing the fastening assembly 22 is correspondingly disposed on the protrusion 14 of the machine body 10, and the fixing groove is disposed on the guide surface.

During the process of installing the water tank assembly 20, a user pushes the water tank assembly into the installation groove 13 along the guide surface, and the first buckle 221 and the second buckle 222 are continuously extruded by the guide surface; when the water tank assembly is pushed to the first buckle and the second buckle to reach the fixing groove, the first buckle and the second buckle are clamped into the fixing groove under the action of elastic force, and the water tank assembly 20 is installed on the machine body 10.

On the contrary, when the user unloads the water tank assembly from the mounting groove 13, the first buckle 221 and the second buckle 222 are firstly pressed, so that the first buckle 221 and the second buckle 222 are gradually separated from the fixing groove until the position below the guide surface is reached, at this moment, the connection constraint relation between the water tank assembly and the machine body disappears, and the user can pull out the water tank assembly from the mounting groove.

Of course, when the guide surface is not provided on the machine body 10, the user can press the pressing plate 223 to make the pressing plate 223 move downward, the two cylinders retract from the through hole on the limiting plate 225, and then the water tank assembly 20 is installed in the installation groove 13, and then the pressing plate 223 is loosened to make the buckle assembly 22 bounce under the action of self elasticity and inserted into the fixing groove, so that the fixing of the water tank assembly 20 can also be realized.

As shown in fig. 7, the water tank assembly 20 is provided inside with an inner chamber 212 for containing water, wherein the water added to the inner chamber 212 includes not only pure water but also cleaning water to which a cleaning liquid is added.

A water outlet 23 is provided on the water tank assembly 20, the water outlet 23 of the water tank assembly 20 is butted with a water inlet 16 provided on the machine body 10, and a water pumping assembly (not shown in the figure) communicating with the water inlet 16 is provided in the machine body 10.

As shown in fig. 2, a rag disc 40 is disposed under the chassis of the robot body, and a water spraying opening (not shown) is disposed above or adjacent to the rag disc 40. In the working process of the cleaning robot of the present disclosure, since the water outlet 23 of the water tank assembly 20 is in butt joint with the water inlet 16 of the robot body 10, water in the inner cavity 212 can be pumped into the water spraying opening above the rag disc 40 under the action of the water pumping assembly, so as to be sprayed onto the rag disc 40.

As shown in fig. 2 and 5, a tank cover 26 is further disposed on the water tank assembly 20, and when the water amount in the water tank assembly 20 is insufficient, the user opens the tank cover 26 and adds water into the water tank assembly 20, and then closes the tank cover 26 to close the water tank after the water addition is completed.

As shown in fig. 3 to 7, the dust exhaust channel 24 is further disposed on the water tank assembly 20, and the dust exhaust channel 24 is independent from the inner cavity 212 of the water tank assembly 20. And after the water tank assembly 20 is fitted into the mounting groove 13, the dust discharge passage 24 communicates with a dust collection assembly provided in the machine body 10, the dust collection assembly including a dust box 17 provided in the machine body 10 and a dust discharge passage 18 extending from the dust box 17.

In the cleaning robot of this disclosure, rationally configured the dust and retrieved the structure with water tank water supply, can guarantee the volume of water tank set spare 20 from this, also guaranteed simultaneously that cleaning robot returns the butt joint of station back and basic station dust absorption passageway for the dust in the collection dirt subassembly is retrieved to basic station accessible air duct system.

As shown in fig. 6 and 7, in one embodiment of the present disclosure, the dust exhaust passage 24 occupies a portion of the space inside the box 21, and the remaining space is an inner cavity 212 for containing water.

As shown in fig. 4 and 5, the outlet of the dust exhaust channel 24 extends to the outside side wall of the water tank assembly 20 and is configured for docking with a dust extraction channel on a base station. When the cleaning robot disclosed by the invention is used for collecting dust, the outlet of the dust exhaust channel 24 is in butt joint with the dust suction channel on the base station, the base station is started to generate negative pressure, so that garbage and dust in the dust box 17 are sucked out of the dust box 17, sequentially pass through the dust outlet channel 18, the dust exhaust channel 24 and the dust suction channel, and finally reach the main dust box on the base station. Therefore, the user does not need to frequently clean the garbage on the dust box 17 in the cleaning robot, and the garbage in the main dust box of the base station can be directly cleaned, so that the cleaning frequency of the user is reduced.

Furthermore, a dust blocking valve can be arranged at the dust outlet of the dust box 17 to prevent the dust or dirt in the dust box 17 from flying out of the dust box 17 to pollute the cleaned working surface in the normal working process of the cleaning robot.

As shown in fig. 2 and 5, in one embodiment of the present disclosure, the water tank assembly 20 further includes a sealing cover 25 sealing an outlet of the dust exhaust passage 24. During the normal operation of the cleaning robot, the sealing cover 25 can prevent the garbage or dust in the dust box 17 from flying out of the dust exhaust passage 24 and polluting the cleaned working surface; when dust collection is needed, after the outlet of the dust exhaust channel 24 is butted with the dust suction channel of the base station, the sealing cover 25 can be opened under the action of negative pressure in the dust suction channel to communicate the dust suction channel with the dust exhaust channel 24. In order to facilitate the opening of the sealing cover 25 under the negative pressure of the dust suction passage, the sealing cover 25 may be made of a soft rubber material, and as shown in fig. 5, only the upper end of the sealing cover 25 is fixed to the housing 21, and the lower end is in a free state.

As shown in fig. 6, the dust exhaust passage 24 is provided at one end of the water tank assembly 20, and a distance between a center of the dust exhaust passage 24 and a center of the water tank assembly 20 is 20mm to 350mm, i.e., L2 in fig. 6 ranges from 20mm to 350mm. Wherein, the center of the water tank assembly 20 refers to a center line of the water tank assembly 20 in a general advancing direction of the cleaning robot, and the center of the dust exhaust passage 24 refers to a center line of the dust exhaust passage 24 in the general advancing direction of the cleaning robot, and the distance between the two center lines is the distance between the two center lines.

Because the distance L2 between the center of the dust exhaust channel 24 and the center of the water tank assembly 20 is in the range of 20mm to 350mm, the problem that the dust exhaust channel 24 and functional elements in the machine body 10 are difficult to arrange due to too small distance between the two can be avoided; the problem that the working efficiency is reduced due to air leakage when the base station recovers dust because the dust absorption channel and the dust exhaust channel 24 are easily inclined when being butted because the distance between the dust absorption channel and the dust exhaust channel is too large can be solved.

As shown in fig. 3 and 8, in one embodiment of the present disclosure, the end surfaces 27 of the opposite ends of the water tank assembly 20 are configured to be perpendicular to the installation direction of the water tank assembly 20, that is, the installation direction of the water tank assembly 20 is a vertical upward direction with respect to the direction in fig. 3, the end surfaces 27 of the opposite ends of the water tank assembly 20 extend in a horizontal direction in fig. 3, and the inlet and the outlet 23 of the dust exhaust passage 24 are provided on the end surfaces 27 of the opposite ends of the water tank assembly 20, so that the end surfaces 27 of the opposite ends of the water tank assembly 20 can be well installed in the installation groove 13, and better attached to the installation groove 13.

Further, as shown in fig. 3 and 8, the opposite ends of the water tank assembly 20 are provided with extending portions 28 extending toward the installation direction of the water tank assembly 20, that is, based on the direction in fig. 3, the extending portions 28 extend in the vertical upward direction, the outer edges of the water tank assembly 20 extend in the horizontal direction, and the outer edges of the water tank assembly 20 form clamping grooves 29 between the extending portions 28 on the two sides of the extending portions 28 and the outer edges of the water tank assembly 20; the mounting groove 13 is configured to have a shape adapted to the water tank assembly 20 such that the catch 29 structure can reduce the shaking of the water tank assembly 20 in the mounting groove 13 after the water tank assembly 20 is mounted in the mounting groove 13 through the extension 28 and the catch 29 structure.

As shown in fig. 8, in one embodiment of the present disclosure, the water outlet 23 of the water tank assembly 20 includes a first pipe joint 231 and a check valve 232 located within the first pipe joint 231; the water inlet 16 of the body 10 includes a second pipe joint 161 and a top bar 162 in the second pipe joint 161; when the water tank assembly 20 is installed in the installation groove 13, the push rod 162 pushes the one-way valve 232 to be in an open state; a seal is provided on an outer circumferential surface of the second pipe joint 161 to configure the first pipe joint 231 and the second pipe joint 161 to be sealingly connected together. Because the water tank assembly 20 is provided with the one-way valve 232 and the machine body 10 is provided with the mandril 162, the one-way valve 232 can be automatically closed when the water tank assembly 20 is taken down from the machine body 10, and water is prevented from flowing out of the water tank; after the water tank assembly 20 is installed in the installation groove 13, the push rod 162 automatically pushes the check valve 232 to an open state, thereby facilitating the pumping assembly to pump out the water.

The second aspect of the present disclosure also provides a cleaning system including a base station (not shown in the drawings) and the aforementioned cleaning robot. When the cleaning robot returns to the base station, the dust exhaust passage 24 of the cleaning robot can be butted with the dust suction passage of the base station, and the dust in the dust collection assembly can be recovered to the dust bucket for storage under the action of the air duct system.

Application scenario one

Before the cleaning robot starts cleaning work, a user opens the water tank cover 26 and adds water into the water tank assembly 20, and then covers the water tank cover 26 to close the water tank; then the water tank assembly 20 is installed into the installation groove 13; in the process of installing the water tank assembly 20 by a user, the guide surface on the protrusion 14 continuously presses the buckle assembly 22, so that the buckle assembly 22 continuously retracts into the tank body 21, until the buckle assembly 22 moves to the fixing groove, the buckle assembly 22 bounces under the action of the elastic force of the buckle assembly 22 and is inserted into the fixing groove, and the water tank assembly 20 is fixed; and during the installation process, the water outlet 23 of the water tank assembly 20 is gradually butted with the water inlet 16 on the machine body 10, the ejector rod 162 on the water inlet 16 pushes the one-way valve 232 on the water outlet 23 to be in an open state, and the first pipe joint 231 on the water tank assembly 20 is connected with the second pipe joint 161 on the machine body 10 in a sealing manner. Because the water outlet 23 of the water tank assembly 20 is connected with the water inlet 16 of the machine body 10 in an abutting mode, in the working process of the cleaning robot, water in the water tank assembly 20 is sprayed onto the rag disc 40 from the water spray opening under the action of the water pumping assembly, and the cleaning robot can continuously scrub the ground by using the wet rag disc 40.

When the water in the water tank assembly 20 is lower than a set amount in the process of scrubbing the ground by the cleaning robot, the cleaning robot gives an alarm to prompt a user to add water; after receiving the water adding alarm signal, the user presses the water tank assembly 20 downwards in the direction of the pressing plate 223 and the notch 15, and when the user presses the pressing area of the pressing plate 223, the pressing plate 223 moves downwards to retract the two cylinders from the fixing grooves, so that the user takes down the water tank assembly 20 from the mounting groove 13, and then the water adding step is repeated until the work of the cleaning robot is completed.

Application scenario two

When the amount of garbage in the dust box 17 in the machine body 10 reaches a preset amount, the cleaning robot of the present disclosure will move to the base station, and the outlet of the dust exhaust channel 24 will be butted with the dust suction channel on the base station; then the base station opens the negative pressure, the sealing cover 25 at the outlet of the dust exhaust channel 24 is opened, so that the outlet of the dust exhaust channel 24 is communicated with the dust suction channel on the base station, then the garbage and the dust in the dust box 17 are sucked out from the dust box 17, sequentially pass through the dust outlet channel 18, the dust exhaust channel 24 and the dust suction channel, and finally reach the dust barrel on the base station, after the dust collection termination condition is met, the negative pressure is closed at the base station, the sealing cover 25 is closed immediately, and the cleaning robot leaves the base station to continue cleaning.
