[0040] This application proposes a cleaning device, please refer to Figures 1 to 3 as well as Fig.12 The cleaning device 100 includes a machine body 10 and a decorative panel 20 .

[0041] The cleaning device 100 may be a self-propelled cleaning robot, a hand-pushed cleaning robot, a handheld vacuum cleaner, a handheld mop, or other equipment used to clean environmental dirt; the cleaning device 100 may also be a device that cooperates with a cleaning robot or other equipment used to clean environmental dirt, specifically a base station device such as a cleaning station, an emptying station, or a maintenance station; the cleaning device 100 may also be other types of devices, which are not listed one by one here.

[0042] The cleaning device 100 is usually provided with a shell part for loading components, and the shell part can be made of hard metal or hard plastic material, or can be made of flexible plastic or other materials, which is not specifically limited here.

[0043] The cleaning device 100 for cleaning the surrounding environment is usually provided with a cleaning part for cleaning garbage. The cleaning part may be a cleaning brush, a cleaning cloth, a cleaning line and other components. The cleaning components may be driven by a driving part installed on the shell part to perform a cleaning movement so that the dirt in the surrounding environment is swept and concentrated to the sewage suction port opened on the cleaning device 100.

[0044] The cleaning device 100 may also have a suction part. For the cleaning device 100 for cleaning the surrounding environment, the suction part can suck out the dirt in the surrounding environment. For the equipment matched with the equipment for cleaning the surrounding environment, the suction part can suck out the dirt in the dirt collection box of other cleaning devices 100. The suction part is usually equipped with a power part to provide negative pressure for sucking out the dirt. The suction part also has a pipeline pneumatically connected to the power part, an air suction port connected to the pipeline, an exhaust port and other structures to realize the suction function.

[0045] Of course, the cleaning device 100 may also have other structures, for example, driving parts such as walking wheels and walking tracks that can realize self-movement, and a detection part for detecting the surrounding environment and a control part electrically connected to the detection part, so that the movable cleaning device 100 can realize automatic obstacle avoidance, which will not be elaborated here.

[0046] The machine body 10 can be understood as a shell part and a control part arranged on the shell part, or a component combining the shell part, the control part and other parts.

[0047] At least two push switches 40 are arranged on the machine body 10. The at least two push switches 40 can be understood as trigger switches or trigger circuits arranged on the PCB board. The push switches 40 can generate corresponding electrical signals after being pressed by external force, and transmit them to controllers such as PLC or microprocessors through circuits. After receiving the electrical signals, the controller controls the operation of corresponding electronic devices.

[0048] The decorative plate 20 is installed on the machine body 10. The operator can press the decorative plate 20 to make the decorative plate 20 elastically deform or partially displace and then touch the key switch 40. Different from the flexible pressing plate made of soft rubber material, the decorative plate 20 in the present application is a plate with a certain rigidity. The decorative plate 20 can be made of metal, plastic or other synthetic materials, which is not specifically limited here. When a force is applied locally to the decorative plate 20, the pressed part is not easy to be elastically deformed, but the part under force is easy to be elastically deformed compared with other parts that are not under force.

[0049] Specifically, the decorative plate 20 includes a decorative body 201 connected to the machine body 10 and at least two triggering parts 202 extending from the decorative body 201. Each triggering part 202 is located on a side of the key switch 40 at a corresponding position away from the machine body, and each triggering part 202 can be movably arranged relative to the decorative body 201. Specifically, each triggering part 202 is driven by an external force to produce elastic deformation in the direction of the force applied, and the force direction is adjusted to the force applied in the direction of the key switch 40, so that each triggering part 202 can move toward the corresponding key switch 40, and finally touch or press the key switch 40 at the corresponding position.

[0050] It is understandable that the decoration body 201 and the machine body 10 can be fixedly connected by bonding, screwing, etc., or detachably connected by clamping, snapping, buckling, etc., and no specific limitation is made here.

[0051] It should be noted that the decorative panel 20 can be arranged in a long strip shape, and the middle part of the decorative panel 20 is connected to the machine body 10 to form a decorative body 201. The two ends of the decorative panel 20 are free ends and are arranged opposite to the key switch 40 or abut against the key switch 40 to form trigger parts 202 respectively; the decorative panel 20 can also be arranged in a long strip shape, and a plurality of strip-shaped notches are spaced apart in the length direction of the decorative panel 20, and the portion between any two of the notches forms a trigger part 202; of course, the panel can also be set to other shapes, which are not listed one by one here.

[0052] The decorative plate 20 in the technical solution of the present application includes a decorative body 201 and at least two triggering parts 202 extending from the decorative body 201. By connecting the decorative body 201 with the machine body 10, each triggering part 202 is arranged on the side of the key switch 40 at the corresponding position away from the machine body, so that each triggering part 202 can move along the direction of the external force after being driven by an external force, so as to be able to press and trigger the key switch 40 at the corresponding position. Such an arrangement allows multiple key switches 40 to be triggered by different triggering parts 202 on the same decorative plate 20, so as to avoid too many key plates being arranged to affect the waterproof performance of the cleaning device 100, and to avoid each key switch 40 needing to be separately arranged with a key plate and occupying the surface of the cleaning device 100, thereby achieving the purpose of streamlining the structure, reducing the difficulty of installation, and improving the stability and reliability of the structure.

[0053] In some embodiments of this application, please refer to Figures 1 to 3The machine body 10 is provided with a laser radar 12 protruding from the top, and the decorative plate 20 includes an arc-shaped connecting arm 21 and two elastic arms 22 respectively arranged at both ends of the connecting arm 21. The connecting arm 21 and the two elastic arms 22 are arranged around the laser radar 12. The connecting arm 21 forms a decorative body 201. A gap is provided between the two elastic arms 22, and the two elastic arms 22 form two triggering parts 202. Since there is a gap between the two elastic arms 22, when one of the two elastic arms 22 is pressed, the elastic arm 22 can be displaced relative to the other elastic arm 22, thereby triggering the corresponding key switch 40.

[0054] It can be understood that the top of the laser radar 12 can be expanded outward as a whole with a convex ring, so as to limit the decorative panel 20 in the direction away from the key switch 40 to prevent the decorative panel 20 from falling off in the direction away from the key switch 40. In addition, the laser radar 12 is arranged at this location to facilitate the installation of the decorative panel 20 and make the overall structure more beautiful.

[0055] It should be noted that the shape of the cross-section of the laser radar 12 can be circular, elliptical or other regular or irregular shapes, and the decorative panel 20 is adapted to be configured to match the laser radar 12. The decorative panel 20 can specifically be a circular ring, an elliptical ring or other ring shape adapted to the laser radar 12, and no specific limitation is made here.

[0056] In some embodiments of this application, please refer to Figures 1 to 3 as well as Figure 7 The machine body 10 is formed with an annular mounting groove 11 on the side around the laser radar 12, at least two button switches 40 are arranged in the mounting groove 11, the decorative plate 20 is installed in the mounting groove 11 and covers at least two button switches 40, and the cleaning device 100 includes an elastic member 30, which elastically connects the two elastic arms 22 and seals the gap between the elastic arms 22.

[0057] Obviously, by placing the key switch 40 in the mounting groove 11 and arranging the elastic member 30 to seal the gap, the key switch 40 can be waterproof and dustproof, thereby preventing the key switch 40 or the electronic device electrically connected to the key switch 40 from being damaged. It can be said that the elastic member 30 can be made of silicone or rubber, which is not specifically limited here.

[0058] Considering that there is an annular gap between the decorative plate 20 and the mounting groove 11, further, please refer to Figure 1 , Figure 7 and Fig.10The elastic member 30 includes a sealing ring 31 and an elastic pad 32 connected to the sealing ring 31. The sealing ring 31 is sealed and matched with the annular gap between the decorative plate 20 and the peripheral side wall of the mounting groove 11. The elastic pad 32 is overlapped on the side of the two elastic arms 22 close to the key switch 40. The elastic pad 32 elastically connects the two elastic arms 22. The elastic arms 22 are continuous at the interval to seal the interval between the elastic arms 22. Through this special sealing method, water is not easy to enter between the decorative plate 20 and the key switch 40, and no additional waterproof structure is required between the decorative plate 20 and the key switch to improve the compactness of the overall structure.

[0059] It should be noted that the sealing ring 31 can be tightly fitted on the outer edge of the decorative panel 20 only by elastic action, and the sealing ring 31 can also be bonded and connected to the outer edge of the decorative panel 20 by adhesive components such as glue and stickers. The sealing ring 31 can also be connected to the decorative panel 20 by other connecting parts such as bolts, which is not specifically limited here.

[0060] It is worth mentioning that the elastic pad 32 can be detachably connected to the sealing ring 31, and the elastic pad 32 can also be integrally formed with the sealing ring 31. Considering the replacement of the sealing ring 31 and the elastic pad 32, preferably, the elastic pad 32 is usually integrally formed with the sealing ring 31 to facilitate replacement. In addition, the elastic pad 32 can be fully extended between the two elastic arms 22, or partially extended between the two elastic arms 22, which is not specifically limited here.

[0061] Considering that the sealing ring 31 lacks a limiting structure in the upper and lower directions and may fall off, please refer to Figure 1 and Figure 7 A limiting ring 311 extending along the circumference of the sealing ring 31 is disposed on the inner side thereof. The limiting ring 311 is used to abut against the surface of the decorative plate 20 facing the key switch 40 .

[0062] It can be understood that the abutment between the limit ring 311 and the surface of the decorative panel 20 facing the push switch 40 can effectively prevent the sealing ring 31 from falling off in the direction away from the push switch 40, and the surface of the limit ring 311 facing away from the decorative panel 20 can also abut against the bottom of the mounting groove 11 or the stepped portion provided in the mounting groove 11, thereby being clamped and fixed by the decorative panel 20 and the bottom of the mounting groove 11 or the stepped portion in the mounting groove 11.

[0063] It should be noted that the limiting ring 311 can be a continuous circular ring, or a ring structure formed by multiple arc-shaped strips arranged at intervals, which is not specifically limited here. In addition, the limiting ring 311 can be made of elastic materials such as silicone or rubber, and the limiting ring 311 can be detachably connected to the sealing ring 31, or the limiting ring 311 can be integrally formed with the sealing ring 31. For ease of manufacturing, preferably, the limiting ring 311 and the sealing ring 31 are made of the same material and are integrally formed.

[0064] Similarly, in other embodiments, considering that the elastic member 30 lacks a limit or fixing structure in the up and down directions, it may cause deviation or fall off. Figure 7 , Figure 8 as well as Fig.11 The elastic member 30 includes a first sealing portion 33 and a second sealing portion 34 arranged on the first sealing portion 33. The first sealing portion 33 is connected to the surfaces of the two elastic arms 22 facing the push switch 40, and the second sealing portion 34 is installed between the two elastic arms 22 and is sealed and abutted against the two elastic arms 22.

[0065] It should be noted that the first sealing portion 33 may be detachably connected to the second sealing portion 34, or the first sealing portion 33 may be integrally formed with the second sealing portion 34. There are many ways to connect the first sealing portion 33 to the two elastic arms 22, such as bolt connection, adhesive connection, plug connection, clamp connection, etc. Preferably, the first sealing portion 33 and the two elastic arms 22 may be detachably connected by clamping or plug-in matching.

[0066] For further information, please refer to Figure 7 , Figure 8 and Fig.11 , the surfaces of the two elastic arms 22 facing the corresponding push switches 40 are both recessed with avoidance grooves 221; the second sealing portion 34 is provided with two first convex ribs 341 and a second convex rib 342 side by side on the side facing the elastic arms 22, the two first convex ribs 341 respectively extend into the avoidance grooves 221 of the two elastic arms 22 to clamp the two elastic arms 22, and the second convex rib 342 is clamped in the gap between the two elastic arms 22 to seal the gap.

[0067] It is worth noting that the two first ribs 341 and the second ribs 342 are also made of flexible materials such as silicone or rubber. The distance between the two first ribs 341 and the second ribs 342 is smaller than the thickness of the groove wall of the avoidance groove 221. The groove wall of the avoidance groove 221 is squeezed into the gap between the two first ribs 341 and the second ribs 342, and then the clamping force is applied to the groove wall of the avoidance groove 221 by the elastic action of the two first ribs 341 and the second ribs 342 themselves, thereby ensuring structural stability and sealing.

[0068] It should be noted that the setting of the avoidance groove 221 can provide for the installation of a PCB board or other electronic devices provided with a push button switch 40, thereby increasing the installation space. The setting of the avoidance groove 221 can also allow the groove wall of the avoidance groove 221 to abut against the groove wall or groove bottom of the installation groove 11, thereby preventing the decorative panel 20 from directly abutting against the PCB board or other electronic devices, causing damage to the PCB board and the electronic devices.

[0069] Since the two elastic arms 22 are provided with the avoidance grooves 221, the distance between the parts of the two elastic arms 22 used to trigger the key switch 40 and the key switch 40 is also increased accordingly. In order to prevent the elastic arms 22 from failing to touch the key switch 40 or the travel of the elastic arms 22 being insufficient to trigger the key switch 40, further, please refer to Figure 5 , Figure 7 and Fig.11 , the surfaces of the two elastic arms 22 facing the corresponding key switches 40 are both provided with key blocks 222; the two opposite sides of the first sealing portion 33 are both provided with flexible pads (not marked), and the two flexible pads are respectively sleeved with the key blocks 222 on the corresponding elastic arms 22. The provision of the key blocks 222 can reduce the travel required for the elastic arms 22 to trigger the key switches 40. In other words, the provision of the key blocks 222 can allow the elastic arms 22 to undergo smaller elastic deformation to trigger the key switches 40, thereby increasing the service life of the elastic arms 22 and making the decorative panel 20 more stable and reliable.

[0070] It should be noted that the shape of the key block 222 can be cylindrical, square, cross-shaped, and other regular or irregular shapes, which are not listed here. The surface of the flexible pad facing the key switch 40 can be concavely provided with a slot that matches the shape of the key block 222, and the key block 222 is plugged into the slot. The flexible board provided by the flexible pad can play a buffering role between the key block 222 and the key switch 40, preventing the key block 222 from causing damage to the key switch 40.

[0071] It is worth mentioning that the flexible pad is also made of flexible materials such as silicone or rubber to facilitate the buffering effect between the key block 222 and the key switch 40. The flexible pad and the first sealing part 33 can be an integrally formed setting or a detachable connection setting, which is not specifically limited here.

[0072] Considering that there is a certain distance between the first sealing portion 33 and the two key blocks 222, in order to avoid the lack of stability of the flexible pad between the interval, further, please refer to Figure 5 , Figure 7 and Fig.11The surfaces of the two elastic arms 22 facing the corresponding push switches 40 are both provided with fixing columns 223, and the two flexible pads are both provided with matching holes (not marked) that match the corresponding fixing columns 223, and the fixing columns 223 and the matching holes are plug-fitted.

[0073] In some embodiments of this application, please refer to Figure 5 The surface of the connecting arm 21 adjacent to the key switch 40 is provided with a support bar 211, which is used to abut against the machine body 10, and the two elastic arms 22 of the decorative plate 20 abut against the corresponding key switches 40. Such a configuration enables the decorative plate 20 to have at least three stable support points, thereby preventing one side of the decorative plate 20 from protruding or sinking.

[0074] It is understandable that the support strip 211 may be in contact with the bottom of the mounting groove 11 or with other components disposed in the mounting groove 11, and no specific limitation is made here. The support strip 211 may be in the shape of a long strip or in the shape of an arc disposed along the ring of the decorative plate 20, and the number of the support strips 211 may be one or more, and no specific limitation is made here.

[0075] In view of the fact that electronic devices such as the push switch 40 may be installed on the side of the elastic arm 22 facing the push switch 40, in order to prevent water from entering there, in some embodiments of the present application, water guide blocks 224 are protruding from the side walls of the two elastic arms 22 facing the laser radar 12, and the height of the middle position of the water guide block 224 gradually decreases toward the two ends of the extension direction parallel to the elastic arm 22, so that the water guide block 224 can guide the water flow to the two ends of the extension direction parallel to the elastic arm 22.

[0076] It should be noted that the water guide block 224 can be a convex block with a ridge protruding in the middle and inclined surfaces on both sides, or a convex block with an arc-shaped slope protruding in the middle, or other shapes. In addition, to ensure smooth flow of water, the water guide block 224 can also be provided with an inclined surface inclined toward the direction of the key switch 40, for example, please refer to Figure 3 , Figure 5 as well as Fig. 9 , the arc-shaped protrusion is set to be in the shape of an umbrella surface.

[0077] Based on the consideration of efficient use of the installation space of the cleaning device 100, as well as the consideration of weight reduction and aesthetics of the decorative plate 20, in some embodiments of the present application, please refer to Figure 1 and Figure 3The width of the decorative plate 20 is gradually increased from the connecting arm 21 to the extending direction of the two elastic arms 22. The width of the decorative plate 20 at the connecting arm 21 is smaller than the width of the two elastic arms 22. The smaller width of the connecting arm 21 reduces the rigidity of the connecting arm 21, so that the two elastic arms 22 can be more easily elastically deformed, making it easier for operators to press; the larger width of the two elastic arms 22 is convenient for users to operate.

[0078] In other embodiments of this application, please refer to Figure 1 , Figure 6 as well as Fig.12 The machine body 10 is provided with a laser radar 12 protruding from the top, the decorative plate 20 is provided in a continuous ring shape, the decorative plate 20 is provided around the laser radar 12, the portion of the decorative plate 20 corresponding to the key switch 40 forms the trigger portion 202, and the portion of the decorative plate 20 other than the trigger portion 202 forms the decorative body 201. Since the decorative plate 20 is provided in a ring shape, and the portion of the decorative plate 20 corresponding to the decorative body 201 is fixed, the portion of the decorative plate 20 corresponding to the trigger portion 202 can be elastically deformed after being pressed, so that the corresponding key switch 40 can be triggered.

[0079] It is understandable that there is no gap between the two triggering parts 202 of the annular decorative plate 20, which has a better sealing effect. However, considering that the decorative plate 20 is arranged in a continuous annular shape, the absence of a gap between the two triggering parts 202 will also make the two triggering parts 202 difficult to be pressed. In view of this, the part of the decorative plate 20 corresponding to the triggering part 202 has a first thickness, and the part of the decorative plate 20 corresponding to the decorative body 201 has a second thickness, and the first thickness is less than the second thickness. Such a setting can reduce the rigidity of the triggering part 202, so that the triggering part 202 can be more easily elastically deformed, which makes the triggering part 202 easier to be pressed, thereby improving the operability.

[0080] In the embodiment where the machine body 10 is formed with an annular mounting groove 11 on the peripheral side of the laser radar 12, at least two key switches 40 are arranged in the mounting groove 11, and the decorative plate 20 is installed in the mounting groove 11 and covers the at least two key switches 40. To further enhance the waterproof property and prevent the key switches 40 from being wetted by water, the cleaning device 100 further includes a sealing member 50, which is arranged between the machine body 10 and the decorative plate 20, and the sealing member 50 is sealed and connected to the machine body 10, and the sealing member 50 and the machine body 10 are surrounded to form a sealed cavity 51, and the sealed cavity 51 accommodates at least two key switches 40.

[0081] Please continue to refer to Fig.12Considering that a small amount of water may enter the gap between the decorative plate 20 and the mounting groove 11, in view of this, in one embodiment, the mounting groove 11 has a peripheral side wall and a mounting surface connected to the peripheral side wall, and a ring-shaped active gap is formed between the decorative plate 20 and the peripheral side wall of the mounting groove 11. A recessed area 111 and a guide channel 112 are provided at the mounting surface relative to the active gap. The recessed area 111 extends along the peripheral side of the mounting groove 11, one end of the guide channel 112 passes through the recessed area 111, and the other end of the guide channel 112 is connected to the outside, and the sealing member 50 and at least two key switches 40 are arranged on the portion of the mounting surface other than the recessed area 111.

[0082] It is understandable that, since the recessed area 111 extends along the circumference of the mounting groove 11 , the water falling from the movable gap will first fall into the recessed area 111 , and the water deposited in the recessed area 111 will be discharged to the outside through the guide channel 112 .

[0083] It is worth mentioning that the peripheral side walls of the mounting groove 11 can be arranged at an angle, or the peripheral side walls of the mounting groove 11 can be provided with a guide groove extending from the groove mouth of the mounting groove 11 toward the groove bottom of the mounting groove 11, so as to guide the water entering from the movable gap to the recessed area 111.

[0084] To prevent the decorative plate 20 from shaking and becoming unstable, in some embodiments of the present application, please refer to Figure 1 , Figure 4 as well as Figure 5 A positioning column 23 is provided on the surface of the decorative plate 20 facing the push switch 40 and the machine body 10 is provided with a through hole that cooperates with the positioning column 23; and / or a positioning hole 24 is provided on the surface of the decorative plate 20 facing the push switch 40 and the machine body 10 is provided with a column that cooperates with the positioning hole 24.

[0085] It should be noted that the number of the positioning post 23 can be one, two or more, preferably, the number of the positioning post 23 is at least two, and two has better stability. Similarly, the number of the positioning hole 24 can be one, two or more, and preferably, the number of the positioning hole 24 is two. It can be understood that the stability is insufficient if only one positioning post 23 or only one positioning hole 24 is provided, and the number of the positioning post 23 or more than three positioning holes 24 or positioning posts 23 makes the structure complicated, increases the difficulty of manufacturing, and is not easy to install.

[0086] In order to further improve the stability of the decorative panel 20, in some embodiments of the present application, a plurality of (two or more) hooks 25 are arranged at intervals on the decorative panel 20, one end of the plurality of hooks 25 is connected to the decorative panel 20, and one end of the plurality of hooks 25 away from the decorative panel 20 extends toward the machine body 10 and protrudes laterally to be engaged with the machine body 10.

[0087] It is understandable that the main body of the machine may be provided with a plurality of corresponding slots or holes, and the laterally protruding portion of the hook 25 is engaged with the corresponding slots or holes, thereby playing the role of limiting the decorative plate 20.

[0088] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made under the concept of the present application using the contents of the present application specification and drawings, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
