Detailed implementation manners

[0052] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0053] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners of the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the features, steps, operations, devices, components and / or their combinations.

[0054] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0055] As mentioned in the background art, the cleaning members on existing cleaning devices are usually fixedly arranged or can only move in a single direction. As a result, when the cleaning device performs cleaning work along the corner blind areas such as the corners of walls, the edges of walls, and the edges of obstacles, after the cleaning member collides with an obstacle, it can only retract in a specific direction, thus unable to cover the corner blind areas comprehensively, leaving many cleaning dead corners and having a low cleaning coverage rate. For this reason, the inventors of the present application have designed a new type of cleaning device, which can solve the problem that the cleaning member of the cleaning device in the prior art can only retract in a specific direction after colliding with an obstacle. The cleaning device of the present application will be introduced in detail below with reference to the drawings.

[0056] It should be noted that the "first direction" in the present application refers to the Figure 4 direction indicated by the letter X in the Figure 4 drawing; the "second direction" refers to the Figure 4 direction indicated by the letter Y in the drawing; the "third direction" refers to the

[0057] direction indicated by the letter Z in the Figures 1 to 12 drawing. As shown in the drawing, according to an embodiment of the present application, a cleaning device is provided, which includes a body 10, a cleaning assembly 20, and a switching mechanism 30.

[0058] Specifically, the cleaning component 20 is movably arranged at the bottom of the fuselage 10, and the cleaning component 20 has an expanded position that extends outwards beyond the outer side of the fuselage 10 and a retracted position that retracts to the inside of the fuselage 10; the switching mechanism 30 is arranged on the fuselage 10 and connected to the cleaning component 20, and the switching mechanism 30 is configured to apply a force to the cleaning component 20 to make the cleaning component 20 in the expanded position when the cleaning device is in the initial state, and to retract in different directions when the cleaning component 20 hits an obstacle so that the cleaning component 20 switches from the expanded position to the retracted position. It should be noted that the "initial state" in this application refers to the state where the cleaning component 20 does not come into contact with an obstacle and does not retract when the cleaning device is cleaning the surface to be cleaned.

[0059] When the cleaning device in this embodiment works, the cleaning component 20 arranged at the bottom of the fuselage 10 can clean the surface to be cleaned. During the normal cleaning process of the cleaning device, that is, when the cleaning component 20 does not come into contact with an obstacle, the switching mechanism 30 applies an external force to the cleaning component 20 to make the cleaning component 20 in the expanded position, so that the cleaning area of the cleaning component 20 is larger and the cleaning efficiency of the cleaning device is improved; when the cleaning device cleans corner areas such as the corner of a wall, that is, when the cleaning component 20 comes into contact with an obstacle and the force applied by the obstacle to the cleaning component 20 is greater than the external force applied by the switching mechanism 30 to the cleaning component 20, the cleaning component 20 can switch from the expanded position to the retracted position under the abutting action of the obstacle, so as to fit the wall surface for cleaning, so that there is no cleaning dead angle in the cleaning device and the cleaning effect of the cleaning device is effectively improved. At the same time, during the process of the cleaning component 20 switching positions, since the switching mechanism 30 in this embodiment can retract in different directions when the cleaning component 20 hits an obstacle, the cleaning component 20 can flexibly adjust its own position and angle according to the specific shape of the corner area, effectively preventing the cleaning component 20 from only retracting in a specific direction after colliding with an obstacle, so as to better fit the corner contour for cleaning and further improve the cleaning effect of the cleaning device.

[0060] It can be understood that when the cleaning device leaves the corner area, the external force applied to the cleaning component 20 is cancelled, and the cleaning component 20 can be reset to the expanded position under the external force applied by the switching mechanism 30 to continue cleaning.

[0061] Further, refer to Figures 4 to 6As shown, the fuselage 10 in this embodiment is provided with a water tank 40. The switching mechanism 30 is arranged at the bottom of the water tank 40. The switching mechanism 30 includes a first switching component 31 and a second switching component 32. The first switching component 31 and the second switching component 32 are arranged at intervals at the bottom of the water tank 40 and are respectively connected to the cleaning component 20. Among them, when the cleaning device is in the initial state, both the first switching component 31 and the second switching component 32 apply force to the cleaning component 20 to make the cleaning component 20 in the outward expansion position. When the cleaning component 20 hits an obstacle, both the first switching component 31 and the second switching component 32 are retracted under force to switch the cleaning component 20 from the outward expansion position to the inward contraction position, and the second switching component 32 can drive the cleaning component 20 to swing along the first direction or the second direction during the process of being retracted under force.

[0062] Specifically, in this embodiment, the position switching of the cleaning component 20 is realized through the cooperation of the first switching component 31 and the second switching component 32. When the cleaning device is in the initial state, both the first switching component 31 and the second switching component 32 apply an external force to the cleaning component 20 to make the cleaning component 20 in the outward expansion position. In this way, the combined action of the two components can provide a balanced and stable supporting force for the cleaning component 20, ensuring that the cleaning component 20 remains balanced in the outward extended state, thereby more effectively expanding the cleaning range. Especially when cleaning a large area, the arrangement of the first switching component 31 and the second switching component 32 can ensure that the cleaning component 20 always remains in the outward expansion state, improving the cleaning efficiency. At the same time, when the cleaning component 20 hits an obstacle, both the first switching component 31 and the second switching component 32 are retracted under force to switch the cleaning component 20 from the outward expansion position to the inward contraction position. This dual retraction mechanism provides a more reliable guarantee for the inward contraction of the cleaning component 20. Even if one of the components fails or encounters a large resistance, the other component may still drive the cleaning component 20 to complete the inward contraction action, effectively avoiding excessive collision between the cleaning device and the obstacle and resulting in damage.

[0063] In addition, the second switching component 32 can drive the cleaning component 20 to rotate along the first direction or the second direction during the process of being retracted under force. This design enables the cleaning component 20 to rotate precisely and flexibly through the retraction of the second switching component 32 when encountering special areas such as corners. Thus, it can better fit the surface of the wall corner or other irregularly shaped obstacles for cleaning, effectively removing the stains in these areas and reducing cleaning dead corners.

[0064] Further, refer to Figure 5As shown in the figure, the first switching component 31 in this embodiment includes a guide rod 311, a first slider 312, and a first elastic telescopic member 314. Specifically, the guide rod 311 is disposed in the water tank 40 and extends along the third direction, and the guide rod 311 has a first fixed end 3111 connected to the water tank 40; the first slider 312 has a first guide hole 313, and the first slider 312 is sleeved on the guide rod 311 through the first guide hole 313 and can slide reciprocally along the length direction of the guide rod 311, and the first slider 312 is connected to the cleaning component 20; the first elastic telescopic member 314 is sleeved on the guide rod 311 and is located between the first fixed end 3111 and the first slider 312, and one end of the first elastic telescopic member 314 abuts against the first fixed end 3111, and the other end of the first elastic telescopic member 314 abuts against the first slider 312; wherein, when the cleaning device is in the initial state, the first slider 312 slides along the third direction under the elastic force applied by the first elastic telescopic member 314 so that the cleaning component 20 is in the expanded position; when the cleaning component 20 hits an obstacle, the first slider 312 overcomes the elastic force applied by the first elastic telescopic member 314 and slides in the direction opposite to the third direction, so that the cleaning component 20 is switched from the expanded position to the retracted position.

[0065] Exemplarily, the first elastic telescopic member 314 in this embodiment includes a spring. Of course, in other embodiments of the present application, the first elastic telescopic member 314 can also be set as other elastic structures such as an elastic pad. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0066] Specifically, the guide rod 311 provides guidance for the reciprocating sliding of the first slider 312, ensuring that the first slider 312 can only move along the length direction of the guide rod 311, thereby defining the movement trajectory of the cleaning component 20, making the movement of the cleaning component 20 more stable and controllable. At the same time, the guide rod 311 serves as the installation support structure of the first elastic telescopic member 314, ensuring that the first elastic telescopic member 314 can function properly. The overall structure is simple and has good stability, and can reliably guide the movement of the first slider 312, reducing the shaking and offset of the slider during the movement process, and improving the accuracy and reliability of the movement of the entire cleaning component 20; the first elastic telescopic member 314 can automatically provide a restoring force for the cleaning component 20 to realize the automatic switching of the position of the cleaning component 20, without the need to additionally set a power device to realize the position switching of the cleaning component 20. At the same time, the first elastic telescopic member 314 has a buffering effect, so that the impact force when the cleaning component 20 collides with an obstacle can be effectively reduced, and thus the cleaning component 20 and other related components can be protected from damage, effectively improving the service life and reliability of the cleaning device.

[0067] That is to say, in this embodiment, through the cooperation of the guide rod 311, the first slider 312, and the first elastic telescopic member 314, the position of the cleaning assembly 20 can be flexibly switched. When the cleaning device is in the initial state, the first elastic telescopic member 314 is in a stretched state, so that an elastic force can be applied to the first slider 312 to make the first slider 312 slide along the third direction on the guide rod 311, thereby driving the cleaning assembly 20 to be in an outward-expanded position, so as to expand the cleaning range as much as possible during normal operation; when the cleaning assembly 20 collides with an obstacle, the cleaning assembly 20 drives the first slider 312 to slide along the length direction of the guide rod 311 in a direction opposite to the third direction, thereby compressing the first elastic telescopic member 314 to switch the cleaning assembly 20 from the outward-expanded position to the inward-contracted position, so that the cleaning assembly 20 can fit the wall for cleaning, so that there is no cleaning dead angle in the cleaning device, effectively improving the cleaning effect of the cleaning device. At the same time, it can also prevent the cleaning assembly 20 from colliding with the obstacle excessively and being damaged, and to a certain extent, prolong the service life of the cleaning assembly 20.

[0068] Optionally, the first fixed end 3111 in this embodiment and the water tank 40 can be connected by means of snap connection, welding or screwing. With such a setting, the structure is stable and reliable, and it is convenient for processing.

[0069] Further, as shown in Figure 5 the guide rod 311 in this embodiment further has a first free end 3112. The first free end 3112 is located at one end of the guide rod 311 away from the first fixed end 3111, and the first free end 3112 can swing around the first fixed end 3111 along the first direction or the second direction; a first recess 11 is provided at the bottom of the water tank 40. The first recess 11 is recessed from the bottom of the water tank 40 toward the inside of the water tank 40 and extends along the third direction. A first switching assembly 31 is provided in the first recess 11, and a limiting groove 111 is provided on one side of the first recess 11 close to the first free end 3112. The first free end 3112 is located in the limiting groove 111.

[0070] Specifically, the setting of the first recessed portion 11 provides an installation space for the first switching component 31, and since the first recessed portion 11 is recessed from the bottom of the water tank 40 toward the inner side of the water tank 40, when the first switching component 31 is installed in the first recessed portion 11, the first switching component 31 will not protrude from the bottom of the water tank 40, thereby ensuring the flatness of the bottom of the water tank 40. Since the first recessed portion 11 in this embodiment extends along the third direction, when the first switching component 31 is installed in the first recessed portion 11, the first recessed portion 11 can limit the sliding of the first slider 312, thereby preventing the first slider 312 from being displaced in other directions. At the same time, the setting of the limiting groove 111 can limit the displacement of the guide rod 311 in a direction perpendicular to its own length, thereby ensuring the stability of the position of the guide rod 311 during operation, thereby ensuring that the first slider 312 and the cleaning component 20 connected thereto can reciprocate strictly in the length direction of the guide rod 311, thereby avoiding deviation or shaking, thereby making the movement of the cleaning component 20 more precise and stable. In addition, the setting of the limiting groove 111 can share a part of the force borne by the guide rod 311, especially the lateral force generated during the movement of the cleaning component 20. The limiting groove 111 constrains the first free end 3112, thereby enhancing the overall support stability of the guide rod 311, preventing the guide rod 311 from bending or deforming due to uneven force, thereby effectively ensuring the normal operation of the first switching component 31.

[0071] Further, see Figures 5 to 6As shown in the figure, the second switching component 32 in this embodiment includes a guiding swing rod 321, a second slider 322, and a second elastic telescopic member 324. Specifically, the guiding swing rod 321 is disposed on the water tank 40 and extends along the third direction. The guiding swing rod 321 has a second fixed end 3211 and a second free end 3212. The second fixed end 3211 is connected to the water tank 40. The second free end 3212 is located at one end of the guiding swing rod 321 away from the second fixed end 3211, and the second free end 3212 can swing around the second fixed end 3211 along the first direction or the second direction. The second slider 322 has a second guiding hole 323. The second slider 322 is sleeved on the guiding swing rod 321 through the second guiding hole 323 and can slide reciprocally along the length direction of the guiding swing rod 321, and the second slider 322 is connected to the cleaning component 20. The second elastic telescopic member 324 is sleeved on the guiding swing rod 321 and is located between the second fixed end 3211 and the second slider 322. One end of the second elastic telescopic member 324 abuts against the second fixed end 3211, and the other end of the second elastic telescopic member 324 abuts against the second slider 322. Wherein, when the cleaning device is in the initial state, the second slider 322 slides along the third direction under the elastic force applied by the second elastic telescopic member 324 so that the cleaning component 20 is in the outward expansion position. When the cleaning component 20 hits an obstacle, the second slider 322 overcomes the elastic force applied by the second elastic telescopic member 324 and slides in the direction opposite to the third direction, so that the second elastic telescopic member 324 is in a contracted state and the cleaning component 20 is switched from the outward expansion position to the inward contraction position. During the process of the second switching component 32 retracting under force, the guiding swing rod 321 can drive the cleaning component 20 to swing along the first direction or the second direction.

[0072] Exemplarily, the second elastic telescopic member 324 in this embodiment includes a spring. Of course, in other embodiments of the present application, the second elastic telescopic member 324 can also be set as other elastic structures such as an elastic pad. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0073] Specifically, the guiding swing rod 321 provides a sliding track for the second slider 322, ensuring that the second slider 322 can reciprocate along the length direction of the guiding swing rod 321. At the same time, as part of the structure, it supports the second slider 322 and the cleaning assembly 20 connected thereto. Meanwhile, the guiding swing rod 321 can rotate around the second fixed end 3211 in the first direction or the second direction, which enables the cleaning assembly 20 to not only perform a linear reciprocating motion but also change the angle with the swing of the guiding swing rod 321, thereby adjusting the cleaning direction and cleaning range of the cleaning assembly 20; the setting of the second slider 322 can connect the cleaning assembly 20 and the guiding swing rod 321 to transmit the swing of the guiding swing rod 321 and its own sliding along the length direction of the guiding swing rod 321 to the cleaning assembly 20, so as to change the position of the cleaning assembly 20 in the third direction to meet different cleaning requirements; the second elastic telescopic member 324 can automatically provide a restoring force for the cleaning assembly 20 to realize the automatic switching of the position of the cleaning assembly 20 without additionally setting a power device to realize the position switching of the cleaning assembly 20. At the same time, the second elastic telescopic member 324 has a buffering effect, which can effectively reduce the impact force when the cleaning assembly 20 collides with an obstacle, and further protect the cleaning assembly 20 and other related components from damage, effectively improving the service life and reliability of the cleaning device.

[0074] That is to say, in this embodiment, through the cooperation of the guiding swing rod 321, the second slider 322, and the second elastic telescopic member 324, the position of the cleaning assembly 20 can be flexibly switched. When the cleaning device is in the initial state, the second elastic telescopic member 324 is in a stretched state, so as to apply an elastic force to the second slider 322 to make the second slider 322 slide along the third direction on the guiding swing rod 321, and then drive the cleaning assembly 20 to be in the expanded position to expand the cleaning range as much as possible during normal operation; when the cleaning assembly 20 collides with an obstacle, the cleaning assembly 20 drives the second slider 322 to slide along the length direction of the guiding swing rod 321 in the direction opposite to the third direction, thereby compressing the second elastic telescopic member 324 to switch the cleaning assembly 20 from the expanded position to the retracted position, so that the cleaning assembly 20 can fit the wall for cleaning, making the cleaning device have no cleaning dead corners, effectively improving the cleaning effect of the cleaning device. At the same time, it can also prevent the cleaning assembly 20 from colliding with the obstacle excessively and being damaged, and to a certain extent, extend the service life of the cleaning assembly 20.

[0075] It should be noted that since the second free end 3212 in this embodiment is not connected to the water tank 40, when the second slider 322 slides along the direction opposite to the third direction on the guiding swing rod 321, the guiding swing rod 321 will rotate around the second fixed end 3211 in the first direction or the second direction.

[0076] Optionally, the second fixed end 3211 in this embodiment and the water tank 40 can be connected by means of snap connection, welding or screwing. With such a setting, the structure is stable and reliable, and it is convenient for processing.

[0077] Further, as shown in Figures 5 to 6 FIG. 5, a second recess 12 is provided at the bottom of the water tank 40 in this embodiment, and a second switching assembly 32 is provided in the second recess 12. When the cleaning device is in the initial state, the second switching assembly 32 divides the second recess 12 into a first rotation space 101 and a second rotation space 102; a first stop bar 13 is provided in the first rotation space 101, and the first stop bar 13 extends along the first direction. When the guide swing rod 321 rotates along the first direction, the outer side of the second slider 322 is always in contact with the first stop bar 13, so as to compress the second elastic telescopic member 324 under the stopping action of the first stop bar 13; a second stop bar 14 is provided in the second rotation space 102, and the second stop bar 14 extends along the second direction. When the guide swing rod 321 rotates along the second direction, the outer side of the second slider 322 is always in contact with the second stop bar 14, so as to compress the second elastic telescopic member 324 under the stopping action of the second stop bar 14.

[0078] Specifically, the first stop bar 13 provides guidance and limitation for the rotation of the guide swing rod 321 in the first direction, so that the guide swing rod 321 can only move within the range defined by the first stop bar 13, ensuring the accuracy and stability of the movement; similarly, the second stop bar 14 provides guidance and limitation for the rotation of the guide swing rod 321 in the second direction, so that the guide swing rod 321 can only move within the range defined by the second stop bar 14, ensuring the accuracy and stability of the movement. At the same time, when the guide swing rod 321 rotates in the first direction or the second direction, the second slider 322 compresses the second elastic telescopic member 324 under the action of the first stop bar 13 or the second stop bar 14. After being compressed, the second elastic telescopic member 324 can store energy and release the energy when needed, thereby playing a buffering and shock-absorbing role. For example, when the rotational movement of the guide swing rod 321 suddenly stops or is impacted by an external force, the impact force on the entire cleaning device can be reduced, and the service life of the cleaning device is extended; moreover, the compression of the second elastic telescopic member 324 can also generate a restoring force. When the rotational external force of the guide swing rod 321 disappears, the second elastic telescopic member 324 will rely on its own restoring force to return the guide swing rod 321 to the initial position. That is to say, the second elastic telescopic member 324 also provides power for the reset of the guide swing rod 321.

[0079] In addition, in this embodiment, the second switching component 32 divides the second recess 12 into a first rotation space 101 and a second rotation space 102. This space separation design enables moving components and functional components in different directions to work in their respective independent spaces, avoiding mutual interference, improving the compactness of the entire cleaning device, and effectively utilizing the space at the bottom of the water tank 40.

[0080] Furthermore, referring to Figures 5 to 6 As shown, a first stop edge 15 and a first extension space 16 are further provided in the first rotation space 101 of this embodiment. When the cleaning device is in the initial state, the first stop edge 15 and the second switching component 32 enclose the first rotation space 101. The first extension space 16 is located at the first stop edge 15 and extends away from the first rotation space 101 in a direction away from the first rotation space 101, and the first extension space 16 communicates with the first rotation space 101. When the guiding swing rod 321 rotates to a first predetermined angle along the first direction, the guiding swing rod 321 abuts against the first stop edge 15, and the second slider 322 is located in the first extension space 16.

[0081] Specifically, when the guiding swing rod 321 rotates to the first predetermined angle along the first direction, the guiding swing rod 321 will abut against the first stop edge 15, which clearly defines the rotation angle range of the guiding swing rod 321 in the first direction, enabling it to only perform rotational movement within a specific angle, achieving precise positioning, and ensuring that the movement of the guiding swing rod 321 during the operation of the cleaning device meets the design requirements, avoiding component damage or functional failure that may be caused by excessive rotation. At the same time, the first extension space 16 extends away from the first rotation space 101 in a direction away from the first rotation space 101 and communicates with the first rotation space 101. When the guiding swing rod 321 rotates to the first predetermined angle, the second slider 322 can be located in the first extension space 16, providing additional movement space for the second slider 322 during the rotation of the guiding swing rod 321, enabling it to perform corresponding displacement along with the movement of the guiding swing rod 321, and ensuring the smooth progress of the coordinated movement between the second slider 322, the guiding swing rod 321, and other related components.

[0082] Furthermore, referring to Figures 5 to 6As shown in the figure, a second stop edge 17 and a second extension space 18 are further provided in the second rotation space 102 in this embodiment. When the cleaning device is in the initial state, the second stop edge 17 and the second switching component 32 enclose to form the second rotation space 102. The second extension space 18 is located at the second stop edge 17 and extends from the second stop edge 17 in a direction away from the second rotation space 102, and the second extension space 18 communicates with the second rotation space 102. When the guiding swing rod 321 rotates along the second direction to a second predetermined angle, the guiding swing rod 321 abuts against the second stop edge 17, and the second slider 322 is located in the second extension space 18.

[0083] Specifically, when the guiding swing rod 321 rotates along the second direction to the second predetermined angle, the guiding swing rod 321 will abut against the second stop edge 17, which clearly defines the rotation angle range of the guiding swing rod 321 in the second direction, enabling it to only perform rotational movement within a specific angle, achieving precise positioning, ensuring that the movement of the guiding swing rod 321 during the operation of the cleaning device meets the design requirements, and avoiding component damage or function failure that may be caused by excessive rotation. At the same time, the second extension space 18 extends from the second stop edge 17 in a direction away from the second rotation space 102 and communicates with the second rotation space 102. When the guiding swing rod 321 rotates to the second predetermined angle, the second slider 322 can be located in the second extension space 18, providing additional movement space for the second slider 322 during the rotation of the guiding swing rod 321, enabling it to perform corresponding displacements along with the movement of the guiding swing rod 321, and ensuring the smooth progress of the coordinated movement between the second slider 322, the guiding swing rod 321, and other related components.

[0084] Furthermore, the first predetermined angle A in this embodiment satisfies the relational expression: A ≤ 65°. For example, A can be set to 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, etc.

[0085] Specifically, when the first predetermined included angle A is greater than 65°, the rotation angle of the guiding swing rod 321 is too large, which may cause the second slider 322 to excessively compress the second elastic telescopic member 324, exceeding the bearing range of the second elastic telescopic member 324, thereby causing the second elastic telescopic member 324 to prematurely fatigue and damage, losing functions such as buffering and resetting. At the same time, the impact force between the guiding swing rod 321 and the first stop edge 15 will also increase due to large-angle rotation, which may cause wear, deformation, or even fracture of the first stop edge 15 or the guiding swing rod 321 itself, affecting the normal operation and service life of the cleaning device.

[0086] Furthermore, the second predetermined angle B in the present embodiment satisfies the relationship: B≤65°, for example, B can be set to 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, etc.

[0087] Specifically, when the second predetermined angle B is greater than 65°, the rotation angle of the guide swing arm 321 is too large, which may cause the second slider 322 to over-compress the second elastic telescopic member 324, exceeding the bearing range of the second elastic telescopic member 324, thereby causing the second elastic telescopic member 324 to fatigue and be damaged prematurely, and lose the functions of buffering and resetting. At the same time, the impact force between the guide swing arm 321 and the second stop edge 17 will also increase due to the large angle rotation, which may cause the second stop edge 17 or the guide swing arm 321 itself to wear, deform or even break, affecting the normal operation and service life of the cleaning device.

[0088] Further, see Figures 7 to 12 As shown, the cleaning component 20 in this embodiment includes a support plate 21 and a cleaning member (not shown in the drawings), a first connecting column 22 and a second connecting column 23 are arranged at intervals on one side of the support plate 21 close to the water tank 40, the first connecting column 22 has a first avoidance notch 221, the second connecting column 23 has a second avoidance notch 231, and the cleaning member is arranged on the side of the support plate 21 away from the water tank 40; the first switching component 31 includes a first slider 312 and a guide rod 311, and the second switching component 32 includes a second slider 322 and a guide swing rod 321; wherein the first slider 312 has a first avoidance channel 315 for the first connecting column 22 to pass through, and the inner wall surface of the first avoidance channel 315 is provided with a first The first connecting column 22 is provided with a second limiting member 222 on its outer wall surface. The first connecting column 22 penetrates into the first avoidance channel 315 so that the second limiting member 222 is engaged with the first limiting member 316, and the guide rod 311 is located at the first avoidance gap 221. The second slider 322 has a second avoidance channel 325 for the second connecting column 23 to pass through. The inner wall surface of the second avoidance channel 325 is provided with a third limiting member 326. The outer wall surface of the second connecting column 23 is provided with a fourth limiting member 232. The second connecting column 23 penetrates into the second avoidance channel 325 so that the fourth limiting member 232 is engaged with the third limiting member 326, and the guide rocker rod 321 is located at the second avoidance gap 231.

[0089] Illustratively, the cleaning member in this embodiment may be a mop or a brush.

[0090] Specifically, since the first connecting column 22 in this embodiment passes through the first avoidance channel 315 of the first slider 312 so that the second limiter 222 is clamped to the first limiter 316, and the second connecting column 23 passes through the second avoidance channel 325 of the second slider 322 so that the fourth limiter 232 is clamped to the third limiter 326, such a configuration can achieve accurate connection between the support plate 21 of the cleaning component 20 and the first switching component 31 and the second switching component 32, so that the relative positions between the various components can be fixed, ensuring that the various components of the cleaning device will not be randomly displaced or shaken during operation. At the same time, the first avoidance notch 221 of the first connecting column 22 cooperates with the guide rod 311, and the second avoidance notch 231 of the second connecting column 23 cooperates with the guide swing rod 321, providing a specific movement space and guide path for the guide rod 311 and the guide swing rod 321, so that they can move on a specific trajectory, while avoiding interference with the connecting column and other components, ensuring the smoothness of the movement of each component.

[0091] Further, see Figure 8 as well as Figure 10 As shown, the first limiting member 316 in this embodiment includes a first limiting rib 317, which protrudes from the inner wall surface of the first avoidance channel 315 and extends circumferentially along the first avoidance channel 315, and the second limiting member 222 includes a second limiting rib 223, which protrudes from the outer wall surface of the first connecting column 22 and extends circumferentially along the first connecting column 22, and the extension length of the first limiting rib 317 is greater than the extension length of the second limiting rib 223, so that the second limiting rib 223 can move along the extension direction of the first limiting rib 317.

[0092] Specifically, the first limiting rib 317 and the second limiting rib 223 extend in the circumferential direction, and they cooperate with each other to limit the relative movement between the first connecting column 22 and the first avoidance channel 315 in the radial direction, ensuring that the first connecting column 22 will not shake or deflect excessively in the first avoidance channel 315, so that the cleaning component 20 and the first switching component 31 maintain a relatively fixed position relationship in the radial direction. At the same time, since the extension length of the first limiting rib 317 is greater than the extension length of the second limiting rib 223, the second limiting rib 223 can move in the extension direction of the first limiting rib 317, which provides guidance for the movement of the first connecting column 22 relative to the first slider 312 in the axial direction, so that the first connecting column 22 can move within a specific axial range, realizing the relative movement between the cleaning component 20 and the first switching component 31 in the axial direction, thereby facilitating the rotation of the cleaning component 20 in the first direction or the second direction.

[0093] Further, see Figures 8 to 9As shown, the third limiting member 326 in this embodiment includes a third limiting rib 327. The third limiting rib 327 protrudes from the inner wall surface of the second avoidance channel 325 and extends along the circumferential direction of the second avoidance channel 325. The fourth limiting member 232 includes a fourth limiting rib 233. The fourth limiting rib 233 protrudes from the outer wall surface of the second connecting column 23 and extends along the circumferential direction of the second connecting column 23. Moreover, the extension length of the third limiting rib 327 is greater than that of the fourth limiting rib 233, so that the fourth limiting rib 233 can move along the extension direction of the third limiting rib 327.

[0094] Specifically, the third limiting rib 327 and the fourth limiting rib 233 extend along the circumferential direction. Their cooperation can limit the relative movement in the radial direction between the second connecting column 23 and the second avoidance channel 325, ensuring that the second connecting column 23 does not shake or shift excessively in the second avoidance channel 325, and keeping the cleaning assembly 20 and the second switching assembly 32 in a relatively fixed positional relationship in the radial direction. At the same time, since the extension length of the third limiting rib 327 is greater than that of the fourth limiting rib 233, the fourth limiting rib 233 can move in the extension direction of the third limiting rib 327. This provides guidance for the movement of the second connecting column 23 relative to the second slider 322 in the axial direction, enabling the second connecting column 23 to move within a specific axial range, realizing the relative movement between the cleaning assembly 20 and the second switching assembly 32 in the axial direction, and thus facilitating the rotation of the cleaning assembly 20 along the first direction or the second direction.

[0095] Combined with the above embodiments, it can be known that in this application, a first switching assembly 31 and a second switching assembly 32 are provided on the body 10. The first slider 312 of the first switching assembly 31 is connected to the first connecting column 22 of the support plate 21, and the second slider 322 of the second switching assembly 32 is connected to the second connecting column 23 of the support plate 21. In this way, when the cleaning assembly 20 collides with an obstacle, it can drive the cleaning assembly 20 to rotate along the first direction or the second direction, thereby realizing the multi-directional collision retraction of the cleaning assembly 20, enabling the cleaning assembly 20 to fully cover the corner blind areas, and effectively improving the cleaning coverage rate of the cleaning device.

[0096] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0097] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. Without further statement, the above terms have no special meaning, and thus should not be construed as limiting the scope of protection of the present application.

[0098] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
