Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning robot and a cleaning system. Background Art

[0002] The face cover of the cleaning robot covers the garbage collection assembly for collecting garbage. In order to suck the garbage and dust on the ground into the garbage collection assembly for collection and storage, the garbage collection assembly needs to be in a negative pressure state. Therefore, when the cleaning robot is in use, it is necessary to ensure that the face cover covering the garbage collection assembly is always in a closed state to ensure the sealing of the garbage collection assembly. At the same time, the face cover of the cleaning robot can also ensure the flatness and beauty of the appearance of the cleaning robot.

[0003] In the related art, the face cover of the cleaning robot is detachably mounted on the robot body, and the installation status of the face cover can be detected by a detection switch. However, due to the structural limitations of the detection switch itself, there is still a problem that the face cover is not on the robot body, but the system reports that the face cover is installed in place, or the face cover is installed in place on the robot body, but the system still issues a reminder that the face cover is not installed or is not installed in place, etc., and the accuracy of the face cover installation status detection is low.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Reference below Figure 1-Figure 10 The cleaning robot 100 according to an embodiment of the present utility model is described. The cleaning robot 100 here can be a sweeping robot, a sweeping and mopping robot, a floor scrubber, a vacuum cleaner, etc.

[0039] See also Figure 1-Figure 2 According to an embodiment of the utility model, the cleaning robot 100 includes a robot body 10 and a face cover 20 , and the face cover 20 is detachably arranged on the top of the robot body 10 , that is, the face cover 20 can serve as the appearance structure of the cleaning robot 100 to cover part of the structure of the robot body 10 .

[0040] Specifically, the face cover 20 of the cleaning robot 100 can cover the garbage collection assembly for collecting garbage. In order to suck the garbage and dust on the ground into the garbage collection assembly for collection and storage, the garbage collection assembly needs to be in a negative pressure state. Therefore, when the cleaning robot 100 is in use, it is necessary to ensure that the face cover 20 covering the garbage collection assembly is always in a closed state, so as to ensure the sealing of the garbage collection assembly. At the same time, the face cover 20 of the cleaning robot 100 can also ensure the flatness and beauty of the appearance of the cleaning robot 100.

[0041] See also Figure 3 and Figure 4 The cleaning robot 100 further includes a state detection component 30 , which is disposed on the robot body 10 . The state detection component 30 includes a detection switch 31 , which is used to detect the installation state of the face cover 20 on the robot body 10 .

[0042] The “installation status” here refers to the status of the face cover 20 relative to the robot body 10, including the face cover 20 being in an effectively installed covering status on the robot body 10 (i.e., the status of being installed in place on the robot body 10), the face cover 20 being in a virtual covering status on the robot body 10, the face cover 20 not being installed in place on the robot body 10, and the face cover 20 not being on the robot body 10.

[0043] The state detection assembly 30 also includes a pusher 32, which is suitable for pushing the detection switch 31 to close under the drive of the face cover 20. Specifically, the pusher 32 can push the detection switch 31 to close under the pressure of the face cover 20. If the detection switch 31 is closed, it can be judged that the face cover 20 has been installed in place on the robot body 10; if the detection switch 31 is not closed, it can be judged that the face cover 20 is in a virtual cover state on the robot body 10, or the face cover 20 is not installed in place on the robot body 10, or the face cover 20 is not on the robot body 10. Exemplarily, when the detection switch 31 is closed, the detection switch 31 is connected to the detection circuit to realize the judgment that the face cover 20 has been installed in place on the robot body 10.

[0044] However, due to the structural limitations of the detection switch in the related technology, there is still a problem that the face cover is not originally on the robot body, but the detection switch is mistakenly closed due to shaking, and the system mistakenly reports that the face cover is in place; or the face cover has been installed in place on the robot body, but the detection switch is shaken, which increases the moving stroke of the pusher and makes the detection switch not close normally. The system still issues a reminder that the face cover is not installed, and the accuracy of the face cover installation status detection is low.

[0045] Please refer again Figure 4 In some embodiments, the pushing member 32 has a guide portion 3232. When the pushing member 32 pushes the detection switch 31 to close, the guide portion 3232 can guide the detection switch 31 to cooperate with the pushing member 32, and can also correct the position of the detection switch 31 to avoid the button 311 of the detection switch 31 from shaking significantly and causing the button 311 to fail to cooperate with the pushing member 32.

[0046] According to the cleaning robot 100 of the present utility model embodiment, by providing the guide portion 3232, the pusher 32 can guide the detection switch 31 to cooperate with the pusher 32 during the process of pushing the detection switch 31 to close, and can also correct the position of the detection switch 31 to avoid the situation where the button 311 of the detection switch 31 does not cooperate with the pusher 32 due to a large shake, thereby preventing the cover 20 from being originally on the robot body 10 but the button 311 of the detection switch 31 is mistakenly closed due to a large shake. The system falsely reports that the face cover 20 is not installed in place, or the face cover 20 has been installed in place on the robot body 10, but the button 311 of the detection switch 31 shakes significantly, which increases the moving stroke of the push member 32, or the button 311 of the detection switch 31 is stuck on the edge of the groove 310 of the detection switch 31 and cannot be pushed down normally, so that the detection switch 31 is not closed normally, and the system still issues reminders that the face cover 20 is not installed or the face cover 20 is not installed in place, etc., which is beneficial to improve the accuracy of the detection of the installation status of the face cover 20 and effectively reduce the defective rate of the cleaning robot 100.

[0047] Please refer again Figure 4 According to some embodiments of the present invention, the guide portion 3232 includes a guide groove 3233 , and the opening of the guide groove 3233 is arranged toward the detection switch 31 , so that the detection switch 31 can be at least partially inserted into the guide groove 3233 .

[0048] Specifically, during the process of installing the face cover 20 on the robot body 10, the pushing member 32 moves under the pressure of the face cover 20. When the face cover 20 is installed in place on the robot body 10, the pushing member 32 can push the detection switch 31 to close. During this process, the pushing member 32 is always coordinated with the detection switch 31 through the guide groove 3233. The guide groove 3233 can constrain the detection switch 31, thereby correcting the position of the detection switch 31 and preventing the detection switch 31 from shaking at a large angle.

[0049] Therefore, by setting the guide portion 3232 to include a guide groove 3233, the detection switch 31 can be prevented from shaking at a large angle. On the one hand, it can prevent the problem that the face cover 20 is not originally on the robot body 10, but the button 311 of the detection switch 31 is mistakenly closed due to a large shaking, and the system mistakenly reports that the face cover 20 is installed in place. On the other hand, it can prevent the increase of unnecessary movement stroke of the push member 32, so that the push member 32 can push the detection switch 31 to close faster, so that the detection switch 31 can more sensitively measure the installation status of the face cover 20, improve the detection accuracy of the status detection component 30, and prevent the face cover 20 from being installed in place on the robot body 10, but the system still issues a reminder that the face cover 20 is not installed or the face cover 20 is not installed in place.

[0050] In addition, a guide groove 3233 is provided on the pushing member 32, which simplifies processing and helps to reduce costs.

[0051] In some embodiments, the cross-sectional area of ​​the guide groove 3233 gradually increases in a direction away from the face cover 20 , and because the notch of the guide groove 3233 faces the detection opening 31 , the notch size of the guide groove 3233 is relatively larger.

[0052] Specifically, Figure 4 As shown, the cross-sectional area of ​​the guide groove 3233 gradually increases from top to bottom. The guide groove 3233 includes a bottom wall and a peripheral wall, and the peripheral wall of the guide groove 3233 can form a conical surface extending outwardly from top to bottom, or can form an arc surface extending outwardly from top to bottom.

[0053] In the above technical scheme, by setting the guide groove 3233 to the above form, on the basis of avoiding the detection switch 31 from shaking at a large angle, on the one hand, the friction between the push member 32 and the detection switch 31 can be reduced, and the problem that the push member 32 cannot be pressed into place or cannot rebound after pressing the push member 32 due to the large friction between the push member 32 and the detection switch 31 can be prevented, thereby further improving the detection accuracy of the state detection component 30. On the other hand, setting a guide groove 3233 with a larger notch size can make it easier to insert the detection switch 31 into the guide groove 3233, which is convenient for installation, solves the problem that the face cover 20 and the robot body 10 are difficult to match and not easy to install, and corrects the position of the detection switch 31 to make it as close to the ideal working state as possible.

[0054] Please continue reading Figure 5 and Figure 6 According to some embodiments of the utility model, the robot body 10 includes a shell 11, the top of the shell 11 has a through hole 111, the detection switch 31 is arranged in the shell 11, and the pushing member 32 includes a push rod 321, one end of the push rod 321 extends from the through hole 111 to the outside of the shell 11, and the push rod 321 is suitable for moving under the pressure of the face cover 20 to push the detection switch 31 to close. When the face cover 20 is installed in place on the robot body 10, the detection switch 31 is closed.

[0055] The shell 11 serves as the appearance structure of the cleaning robot 100. On the one hand, most of the structure of the robot body 10 can be accommodated in the shell 11, so that the structure of the robot body 10 is more concentrated, which is conducive to the realization of structural miniaturization design. On the other hand, the shell 11 protects most of the structure of the robot body 10, especially the electronic components such as the detection switch 31, and blocks external dust and water from entering the interior of the robot body 10, which is beneficial to improving the reliability of the cleaning robot 100 and extending the service life of the cleaning robot 100.

[0056] The pushing member 32 is configured to include a push rod 321, and the push rod 321 and the face cover 20 are pressed against each other so that the detection switch 31 can detect the installation status of the face cover 20. Since the cross-sectional size of the push rod 321 is relatively small, it is only necessary to open a smaller through hole 111 on the top of the shell 11 to expose the push rod 321, which will not have a significant impact on the structural strength of the shell 11. After the face cover 20 is installed on the robot body 10, the face cover 20 can also cover the through hole 111, so opening the through hole 111 on the top of the shell 11 will not affect the appearance of the cleaning robot 100.

[0057] Please refer again Figure 4 , and see further Figure 7 and Figure 8In some embodiments, the push member 32 also includes an elastic transmission portion 322, which is disposed in the housing 11, and the elastic transmission portion 322 is located between the other end of the push rod 321 and the detection switch 31, and the elastic transmission portion 322 has a guide portion 3232 on the side facing the detection switch 31.

[0058] Specifically, the detection switch 31 is located below the elastic transmission part 322 , and the push rod 321 is located above the elastic transmission part 322 .

[0059] During the process of installing the face cover 20 on the robot body 10, the push rod 321 moves downward under the drive of the face cover 20. When the face cover 20 is installed in place on the robot body 10, the push rod 321 can push the elastic transmission part 322 to move downward or deform, and the elastic transmission part 322 can push the detection switch 31 to close.

[0060] When the face cover 20 is removed from the robot body 10, the elastic transmission part 322 can push the push rod 321 to reset, that is, the elastic transmission part 322 can push the push rod 321 to move upward to the initial position, and the detection switch 31 is also reset accordingly to be in the disconnected state, that is, it is judged that the face cover 20 is not installed or the face cover 20 is not installed in place.

[0061] The push rod 321 can be made of a material with relatively high rigidity, such as plastic or hard rubber, and the elastic transmission part 322 can be made of an elastic material, such as soft rubber, so that the elastic transmission part 322 can be elastically deformed.

[0062] In the above technical solution, by setting the pushing member 32 to include an elastic transmission part 322, the elastic transmission part 322 can be used to realize the transmission of power and motion, and can also realize resetting by utilizing its own elastic deformation characteristics, thereby facilitating the subsequent detection of the installation status of the face cover 20.

[0063] In some specific embodiments, the elastic transmission part 322 is a sealing member 323 , and the sealing member 323 is sealedly matched with the housing 11 to cover the through hole 111 .

[0064] When there is dust and water on the outer surface of the housing 11 , even if the dust and water enter the housing 11 through the through hole 111 , the dust and water will only remain in the space formed by the sealing cooperation between the sealing member 323 and the housing 11 .

[0065] Therefore, by setting the elastic transmission part 322 as the seal 323, the seal 323 can ensure the sealing of the through hole 111 on the basis of realizing the transmission of motion and power, thereby preventing dust, water, etc. on the outer shell 11 from entering the interior of the robot body 10 through the through hole 111.

[0066] Please refer again Figure 4 , Figure 7and Figure 8 In some examples, one of the seal 323 and the housing 11 is provided with an annular rib, and the other of the seal 323 and the housing 11 is provided with an annular groove, the annular rib and the annular groove cooperate with each other, and the annular rib and the annular groove both surround the outside of the through hole 111.

[0067] Therefore, by adopting the combination of the annular groove and the annular rib, a sealed connection between the seal 323 and the outer shell 11 can be achieved. Since the annular groove and the annular rib are both surrounded by the outside of the perforation 111, even if dust and water from the outside enter the outer shell 11 through the perforation 111, they cannot pass through the seal 323 and enter the space where the detection switch 31 is located, which is beneficial to improving the waterproof and dustproof effects and extending the service life of the detection switch 31.

[0068] See also Figure 4 and Figure 8 In some specific examples, the annular groove includes a first annular groove 3236, the annular rib includes a first annular rib 112, the first annular groove 3236 is provided on the seal 323, the first annular rib 112 is provided on the outer shell 11, and the first annular rib 112 is plugged into and matched with the first annular groove 3236, so as to realize a sealed connection between the seal 323 and the outer shell 11.

[0069] In other specific examples, the annular groove includes a second annular groove 113, the annular rib includes a second annular rib 3237, the second annular groove 113 is provided on the outer shell 11, the second annular rib 3237 is provided on the seal 323, and the second annular rib 3237 is plugged into and matched with the second annular groove 113, thereby realizing a sealed connection between the seal 323 and the outer shell 11.

[0070] In some other specific examples, the annular groove includes a first annular groove 3236 and a second annular groove 113, the annular rib includes a first annular rib 112 and a second annular rib 3237, the first annular groove 3236 and the second annular rib 3237 are provided on the seal 323, and the first annular rib 112 and the second annular groove 113 are provided on the outer shell 11, thereby realizing a double sealing connection between the seal 323 and the outer shell 11.

[0071] In order to further improve the dustproof and waterproof effects, in some specific examples, a sealing protrusion 3237a is provided on the inner circumferential wall and / or the outer circumferential wall of the annular convex rib, and the sealing protrusion 3237a can be abutted against the groove side wall of the annular groove, so that the annular convex rib and the annular groove achieve an interference fit. The sealing protrusion 3237a can form an annular structure extending along the circumferential direction of the annular convex rib.

[0072] like Figure 4As shown, in the example where the annular groove includes a second annular groove 113 provided on the housing 11 and the annular rib includes a second annular rib 3237 provided on the seal 323 , the sealing protrusion 3237a can be provided on the inner circumferential wall and / or the outer circumferential wall of the second annular rib 3237 .

[0073] In some examples, the seal 323 is connected to the housing 11 by snapping. Figure 7 and Figure 8 As shown, a plurality of slots 3230 may be provided on the seal 323, and the plurality of slots 3230 may be arranged at intervals in the circumferential direction of the seal 323. A plurality of buckles may be provided on the housing 11, and the plurality of buckles may be snap-fitted with the plurality of slots 3230 in a one-to-one correspondence, so that the seal 323 may be fixed on the housing 11.

[0074] Of course, the positions of the slots 3230 and the buckles can also be interchanged. For example, the seal 323 can be provided with a plurality of buckles, which can be arranged at intervals in the circumferential direction of the seal 323, and the housing 11 can be provided with a plurality of slots 3230, and the plurality of buckles can be engaged with the plurality of slots 3230 in a one-to-one correspondence, so that the seal 323 can be fixed to the housing 11. For another example, the seal 323 is provided with a portion of buckles and a portion of slots 3230, and the housing 11 is provided with a portion of buckles and a portion of slots 3230.

[0075] In the above technical solution, by connecting the seal 323 and the housing 11 by snap-fitting, not only the connection reliability of the seal 323 and the housing 11 can be ensured, but also the detachable connection between the seal 323 and the housing 11 can be realized, which is convenient for assembly, disassembly, replacement and maintenance.

[0076] Of course, the seal 323 and the housing 11 may also be connected together in other ways. For example, the seal 323 and the housing 11 may be connected together by bonding, or by interference fit, or by fasteners, which may be selected based on the materials of the seal 323 and the housing 11 and actual conditions.

[0077] Please refer again Figure 4 , Figure 7 and Figure 8 In some examples, the seal 323 includes a sealing portion 3231 and a connecting portion 3235, the sealing portion 3231 can cover the perforation 111, and the sealing portion 3231 is connected to the other end of the push rod 321, the guide portion 3232 is arranged on the side of the sealing portion 3231 facing the detection switch 31, the connecting portion 3235 extends along the circumference of the sealing portion 3231, and the connecting portion 3235 is connected to the sealing portion 3231, and the seal 323 cooperates with the housing 11 through the connecting portion 3235.

[0078] For the sealing part 3231, the sealing part 3231 may include a deformation piece 3238 and a mating boss 3239. The deformation piece 3238 extends along the circumference of the mating boss 3239. The mating boss 3239 has a guide portion 3232 at one axial end and the other axial end is mated with the push rod 321. The thickness of the deformation piece 3238 is relatively small, so that the seal 323 can be deformed under the action of external force. The size of the mating boss 3239 is relatively large, which can ensure the transmission of motion and power.

[0079] Among them, a positioning groove 3234 can be set at the other axial end of the mating boss 3239, and the push rod 321 is plugged into the positioning groove 3234 to ensure that the push rod 321 can move with the movement of the mating boss 3239, and ensure that the mating boss 3239 can move with the movement of the push rod 321.

[0080] As for the connection part 3235, the connection part 3235 may include an annular groove and / or an annular rib to seal with the housing 11. For example, the connection part 3235 may define a first annular groove 3236, and the housing 11 has a first annular rib 112 plugged with the first annular groove 3236; for another example, the connection part 3235 may include a second annular rib 3237, and the housing 11 has a second annular groove 113 plugged with the second annular rib 3237.

[0081] In the above technical solution, by setting the seal 323 to include a sealing portion 3231 and a connecting portion 3235, on the one hand, the connection reliability and sealing between the seal 323 and the housing 11 can be guaranteed, and on the other hand, the seal 323 can realize the transmission of motion and power, thereby improving the detection accuracy and sensitivity of the state detection component 30.

[0082] Please refer again Figure 5 and Figure 6 According to a further embodiment of the present invention, the robot body 10 defines a accommodating cavity 101, the accommodating cavity 101 has a top opening 102, the robot body 10 also includes a dust box (not shown in the figure), the dust box is arranged in the accommodating cavity 101, and the face cover 20 covers the dust box when it is installed in place on the robot body 10.

[0083] Among them, a sealing ring 40 is provided between the face cover 20 and the robot body 10, and the sealing ring 40 is arranged around the dust box. That is to say, when the face cover 20 is installed in place on the robot body 10, the side of the face cover 20 facing the robot body 10 is abutted against the sealing ring 40, and the side of the robot body 10 facing the face cover 20 is abutted against the sealing ring 40, so that the top opening 102 of the accommodating cavity 101 can be sealed by the face cover 20 to ensure the airtightness of the accommodating cavity 101.

[0084] Among them, the sealing ring 40 can be installed on the face cover 20 or on the top of the robot body 10. The sealing ring 40 can be set close to the periphery of the top opening 102 of the accommodating cavity 101 or at a position with a certain distance from the periphery of the top opening 102 of the accommodating cavity 101.

[0085] like Figure 4 As shown, the sealing ring 40 includes a mounting portion 41 and a sealing lip 42, and the mounting portion 41 and the sealing lip 42 can both form an annular structure. The sealing ring 40 is installed on the face cover 20 through the mounting portion 41, one side of the sealing ring 40 is connected to the mounting portion 41 and the other side extends outward, and when the face cover 20 is installed in place on the robot body 10, the sealing lip 42 can be clamped between the face cover 20 and the top of the robot body 10. For example, the sealing lip 42 can be clamped between the face cover 20 and the peripheral edge of the top opening 102 of the accommodating chamber 101, thereby sealing the gap between the face cover 20 and the peripheral edge of the top opening 102 to ensure the airtightness of the accommodating chamber 101.

[0086] In some examples, the perforation 111 is located outside the sealing ring 40, which can reduce the accuracy of the detection of the installation status of the cover 20 and the influence of the airtightness of the accommodating cavity 101 on one hand, and can reduce the design difficulty and cost on the other hand.

[0087] Please refer again Figure 3 In some examples, the state detection component 30 includes at least two, that is, the number of the state detection components 30 can be two or more.

In the embodiment where the number of the magnetic member 13 and the magnetic matching member is multiple, the multiple magnetic members 13 and the multiple magnetic matching members may be mutually attracted one by one.

[0093] Of course, the robot body 10 can be provided with a magnetic member 13 separately, and the cover 20 can be made of a material that can be attracted to the magnetic member 13, that is, the part where the cover 20 and the magnetic member 13 are attracted together forms a magnetic matching part. The cover 20 can protect the magnetic member 13, prevent the magnetic member 13 from being damaged, and prevent the magnetic member 13 from attracting other unnecessary parts such as iron filings.

[0094] In the above technical scheme, by setting the magnetic suction component 13 and the magnetic suction matching component, on the one hand, the face cover 20 can be attracted to the robot body 10, thereby improving the installation reliability and stability of the face cover 20 on the robot body 10 and preventing the face cover 20 from being separated from the robot body 10; on the other hand, the pushing member 32 can be moved under the suction force of the magnetic suction component 13 and the magnetic suction matching component and the gravity of the face cover 20 to push the detection switch 31 to close, so that the detection switch 31 can more sensitively measure the installation status of the face cover 20 and improve the detection accuracy of the status detection component 30.

[0095] In the embodiment where the magnetic component 13 or the magnetic matching component includes multiple ones, in order to ensure the installation reliability and installation stability of the face cover 20 on the robot body 10, the multiple magnetic components 13 or the multiple magnetic matching components can be distributed at different positions on the robot body 10.
