Technical Field
[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology
[0002] Cleaning devices such as robot vacuums, mops, or floor scrubbers are a type of smart home appliance. They can automatically clean the floors in a room using a certain level of artificial intelligence.
[0003] The cleaning components in existing cleaning devices can usually only move in one direction. When cleaning along corners, edges, or obstacles, the cleaning components can only retract in a specific direction after colliding with the obstacle. This results in the inability to fully cover the corners and blind spots, leaving many cleaning dead corners and a low cleaning coverage rate. Utility Model Content
[0004] The main objective of this application is to provide a cleaning device to solve the problem that in the prior art, the cleaning component of the cleaning device can only retract in a specific direction after colliding with an obstacle.
[0005] According to one aspect of this application, a cleaning apparatus is provided, comprising:
[0006] body;
[0007] A cleaning component is movably disposed at the bottom of the body, and the cleaning component has an outwardly expanding position extending outward from the outer side of the body and an inwardly retracted position retracting to the inner side of the body.
[0008] A switching mechanism is disposed on the body and connected to the cleaning component, and the switching mechanism is configured to apply force to the cleaning component when the cleaning device is in the initial state so that the cleaning component is in the outward position, and to retract in different directions when the cleaning component hits an obstacle so that the cleaning component switches from the outward position to the inward position.
[0009] Furthermore, the machine body has a water tank, and the switching mechanism is disposed at the bottom of the water tank. The switching mechanism includes a first switching component and a second switching component. The first switching component and the second switching component are disposed at intervals at the bottom of the water tank and are respectively connected to the cleaning component.
[0010] When the cleaning device is in the initial state, both the first switching component and the second switching component apply force to the cleaning component to make the cleaning component be in the outward position; when the cleaning component hits the obstacle, both the first switching component and the second switching component are retracted by force to make the cleaning component switch from the outward position to the inward position, and the second switching component can drive the cleaning component to swing along the first direction or the second direction during the retraction process.
[0011] Further, the first switching component includes:
[0012] A guide rod is disposed in the water tank and extends in a third direction, and the guide rod has a first fixed end connected to the water tank;
[0013] A first slider has a first guide hole, the first slider is sleeved on the guide rod through the first guide hole and can slide back and forth along the length direction of the guide rod, and the first slider is connected to the cleaning component;
[0014] The first elastic telescopic member is sleeved on the guide rod and located between the first fixed end and the first slider, with one end of the first elastic telescopic member abutting the first fixed end and the other end of the first elastic telescopic member abutting the first slider.
[0015] When the cleaning device is in the initial state, the first slider slides along the third direction under the elastic force applied by the first elastic telescopic member, so that the cleaning component is in the outward position; when the cleaning component hits the obstacle, the first slider overcomes the elastic force applied by the first elastic telescopic member and slides in the opposite direction to the third direction, so that the cleaning component switches from the outward position to the inward position.
[0016] Furthermore, the guide rod also has a first free end, which is located at the end of the guide rod away from the first fixed end, and the first free end can swing around the first fixed end in the first direction or the second direction;
[0017] The bottom of the water tank is provided with a first recessed portion, which is recessed from the bottom of the water tank toward the inner side of the water tank and extends along the third direction. The first switching component is provided in the first recessed portion, and a limiting groove is provided on the side of the first recessed portion near the first free end, and the first free end is located in the limiting groove.
[0018] Furthermore, the second switching component includes:
[0019] A guide swing rod is disposed in the water tank and extends along a third direction. The guide swing rod has a second fixed end and a second free end. The second fixed end is connected to the water tank. The second free end is located at the end of the guide swing rod away from the second fixed end. The second free end can swing around the second fixed end along the first direction or the second direction.
[0020] The second slider has a second guide hole, and the second slider is sleeved on the guide rocker arm through the second guide hole and can slide back and forth along the length direction of the guide rocker arm. The second slider is connected to the cleaning component.
[0021] The second elastic telescopic member is sleeved on the guide rocker and located between the second fixed end and the second slider, with one end of the second elastic telescopic member abutting the second fixed end and the other end of the second elastic telescopic member abutting the second slider.
[0022] When the cleaning device is in the initial state, the second slider slides along the third direction under the elastic force applied by the second elastic telescopic member, so that the cleaning component is in the outward position; when the cleaning component hits the obstacle, the second slider overcomes the elastic force applied by the second elastic telescopic member and slides in the opposite direction to the third direction, so that the second elastic telescopic member is in the contracted state and the cleaning component switches from the outward position to the inward position; during the process of the second switching component retracting under force, the guide rocker arm can drive the cleaning component to swing along the first direction or the second direction.
[0023] Furthermore, the bottom of the water tank is provided with a second recess, and the second switching component is provided in the second recess. When the cleaning device is in the initial state, the second switching component divides the second recess into a first rotation space and a second rotation space.
[0024] A first stop bar is provided in the first rotation space. The first stop bar extends along the first direction. When the guide rocker rotates along the first direction, the outer side of the second slider is always in contact with the first stop bar so as to compress the second elastic telescopic member under the stopping action of the first stop bar.
[0025] A second stop bar is provided in the second rotation space. The second stop bar extends along the second direction. When the guide rocker rotates along the second direction, the outer side of the second slider is always in contact with the second stop bar, so as to compress the second elastic telescopic member under the stopping action of the second stop bar.
[0026] Furthermore, the first rotation space is also provided with a first stop edge and a first extension space. When the cleaning device is in the initial state, the first stop edge and the second switching component enclose the first rotation space. The first extension space is located on the first stop edge and extends from the first stop edge in a direction away from the first rotation space, and the first extension space communicates with the first rotation space. When the guide rocker arm rotates along the first direction to a first predetermined angle, the guide rocker arm abuts against the first stop edge, and the second slider is located within the first extension space; and / or,
[0027] The second rotation space is further provided with a second stop edge and a second extension space. When the cleaning device is in the initial state, the second stop edge and the second switching component form the second rotation space. The second extension space is located on the second stop edge and extends from the second stop edge in a direction away from the second rotation space. The second extension space is connected to the second rotation space. When the guide rocker arm rotates to a second predetermined angle along the second direction, the guide rocker arm abuts against the second stop edge, and the second slider is located in the second extension space.
[0028] Furthermore, the first predetermined angle A satisfies the following relationship: A≤65°; and / or,
[0029] The second predetermined angle B satisfies the relationship: B≤65°.
[0030] Furthermore, the cleaning assembly includes a support plate and a cleaning component. The support plate has a first connecting post and a second connecting post spaced apart on the side near the water tank. The first connecting post has a first clearance notch, and the second connecting post has a second clearance notch. The cleaning component is disposed on the side of the support plate away from the water tank.
[0031] The first switching component includes a first slider and a guide rod, and the second switching component includes a second slider and a guide rocker.
[0032] The first slider has a first clearance channel through which the first connecting post passes. The inner wall of the first clearance channel is provided with a first limiting member, and the outer wall of the first connecting post is provided with a second limiting member. The first connecting post passes into the first clearance channel so that the second limiting member is engaged with the first limiting member, thereby positioning the guide rod at the first clearance notch.
[0033] The second slider has a second clearance channel through which the second connecting post passes. The inner wall of the second clearance channel is provided with a third limiting member, and the outer wall of the second connecting post is provided with a fourth limiting member. The second connecting post passes into the second clearance channel so that the fourth limiting member engages with the third limiting member, thereby positioning the guide rocker arm at the second clearance notch.
[0034] Further, the first limiting member includes a first limiting protrusion, which protrudes from the inner wall surface of the first clearance channel and extends circumferentially along the first clearance channel; the second limiting member includes a second limiting protrusion, which protrudes from the outer wall surface of the first connecting post and extends circumferentially along the first connecting post, and the extension length of the first limiting protrusion is greater than the extension length of the second limiting protrusion, so that the second limiting protrusion can move along the extension direction of the first limiting protrusion; and / or,
[0035] The third limiting member includes a third limiting protrusion, which protrudes from the inner wall of the second clearance channel and extends circumferentially along the second clearance channel. The fourth limiting member includes a fourth limiting protrusion, which protrudes from the outer wall of the second connecting post and extends circumferentially along the second connecting post. The extension length of the third limiting protrusion is greater than the extension length of the fourth limiting protrusion, so that the fourth limiting protrusion can move along the extension direction of the third limiting protrusion.
[0036] When the cleaning device of this application is in operation, the cleaning component located at the bottom of the device can clean the surface to be cleaned. During normal cleaning, when the cleaning component is not in contact with an obstacle, the switching mechanism applies external force to the cleaning component to make it in an outward position, thereby increasing the cleaning area and improving the cleaning efficiency of the device. When cleaning corner areas such as wall corners, when the cleaning component comes into contact with an obstacle and the force exerted by the obstacle on the cleaning component is greater than the external force exerted by the switching mechanism, the cleaning component can switch from the outward position to the inward position under the resistance of the obstacle, thus adhering to the wall surface for cleaning. This eliminates cleaning dead corners and effectively improves the cleaning effect. At the same time, during the switching of the cleaning component's position, because the switching mechanism of this application can retract in different directions when the cleaning component hits an obstacle, the cleaning component can flexibly adjust its position and angle according to the specific shape of the corner area. This effectively prevents the cleaning component from only retracting in a specific direction after colliding with an obstacle, thus better adhering to the corner contour for cleaning and further improving the cleaning effect of the device.

Detailed Implementation
[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0055] As mentioned in the background section, existing cleaning devices typically have fixed cleaning components or can only move in one direction. This results in the cleaning device retracting only in a specific direction after colliding with obstacles such as corners, edges, and corners of walls, failing to fully cover these blind spots and leaving many cleaning dead zones, leading to low cleaning coverage. To address this, the inventors of this application have designed a novel cleaning device that solves the problem of existing cleaning devices retracting only in a specific direction after colliding with obstacles. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.
[0056] It should be noted that "first direction" in this application refers to the attached... Figure 4 The direction indicated by the letter X in the middle; "second direction" refers to the attached... Figure 4 The direction indicated by the letter Y; "third direction" refers to the attached... Figure 4 The direction indicated by the letter Z.
[0057] See Figures 1 to 12 As shown, according to an embodiment of this application, a cleaning device is provided, which includes a body 10, a cleaning component 20, and a switching mechanism 30.
[0058] Specifically, the cleaning component 20 is movably disposed at the bottom of the body 10, and the cleaning component 20 has an outwardly extended position extending outward from the outer side of the body 10 and an inwardly retracted position retracted to the inner side of the body 10; the switching mechanism 30 is disposed on the body 10 and connected to the cleaning component 20, and the switching mechanism 30 is configured to apply force to the cleaning component 20 in the initial state to make the cleaning component 20 be in the outwardly extended position, and to retract the cleaning component 20 in different directions when the cleaning component 20 hits an obstacle, so that the cleaning component 20 switches from the outwardly extended position to the inwardly retracted position. It should be noted that the "initial state" in this application refers to the state in which the cleaning component 20 does not come into contact with an obstacle and therefore does not retract when the cleaning device is cleaning the surface to be cleaned.
[0059] When the cleaning device in this embodiment is working, the cleaning component 20 located at the bottom of the body 10 can clean the surface to be cleaned. During normal cleaning, when the cleaning component 20 is not in contact with any obstacle, the switching mechanism 30 applies an external force to the cleaning component 20 to make it in an outward position, thereby increasing the cleaning area of the cleaning component 20 and improving the cleaning efficiency of the cleaning device. When the cleaning device is cleaning corner areas such as wall corners, when the cleaning component 20 is in contact with an obstacle and the force exerted by the obstacle on the cleaning component 20 is greater than the external force exerted by the switching mechanism 30 on the cleaning component 20, the cleaning component 20 can switch from the outward position to the inward position under the resistance of the obstacle, thereby adhering to the wall surface for cleaning. This eliminates cleaning dead corners and effectively improves the cleaning effect of the cleaning device. Meanwhile, during the switching of the cleaning component 20, since the switching mechanism 30 in this embodiment can retract in different directions when the cleaning component 20 hits the obstacle, the cleaning component 20 can flexibly adjust its 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 the obstacle, thereby better conforming to the corner contour for cleaning, and further improving the cleaning effect of the cleaning device.
[0060] Understandably, when the cleaning device leaves the corner area, the external force on the cleaning component 20 is removed, and the cleaning component 20 can be reset to the outward position under the action of the external force applied by the switching mechanism 30 so as to continue cleaning.
[0061] Further, see Figures 4 to 6As shown, the body 10 in this embodiment has a water tank 40, and a switching mechanism 30 is disposed 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 spaced apart at the bottom of the water tank 40 and are respectively connected to the cleaning component 20. 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 be 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 by force to switch the cleaning component 20 from the outward expansion position to the inward expansion position. During the retraction process, the second switching component 32 can drive the cleaning component 20 to swing along the first direction or the second direction.
[0062] Specifically, in this embodiment, the position switching of the cleaning component 20 is achieved through the coordinated action of the first switching component 31 and the second switching component 32. When the cleaning device is in its initial state, both the first switching component 31 and the second switching component 32 apply external force to the cleaning component 20, causing it to be in an outward-expanding position. Thus, the combined action of the two components provides balanced and stable support for the cleaning component 20, ensuring that it remains balanced while extending outwards, thereby more effectively expanding the cleaning range. Especially when cleaning large areas, the arrangement of the first switching component 31 and the second switching component 32 ensures that the cleaning component 20 always remains in an outward-expanding state, improving cleaning efficiency. Simultaneously, when the cleaning component 20 collides with an obstacle, both the first switching component 31 and the second switching component 32 retract under force, causing the cleaning component 20 to switch from an outward-expanding position to an inward-retracting position. This dual retraction mechanism provides a more reliable guarantee for the inward retraction of the cleaning component 20. Even if one component malfunctions or encounters significant resistance, the other component may still be able to drive the cleaning component 20 to complete the inward retraction action, thereby effectively preventing excessive collisions between the cleaning device and obstacles that could lead to damage.
[0063] In addition, the second switching component 32 can drive the cleaning component 20 to rotate in the first or second direction during the retraction process under force. This design allows the cleaning component 20 to rotate precisely and flexibly when encountering special areas such as corners, through the retraction of the second switching component 32, so as to better fit the corners or other irregularly shaped obstacles for cleaning, effectively remove stains in these areas, and reduce cleaning dead corners.
[0064] Further, see Figure 5As shown, 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 on the water tank 40 and extends along a 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, the first slider 312 is sleeved on the guide rod 311 through the first guide hole 313 and can slide back and forth 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 located between the first fixed end 3111 and the first slider 312, and ... One end of the retractable 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. When the cleaning device is in the initial state, the first slider 312 slides along a third direction under the elastic force applied by the first elastic telescopic member 314 to make the cleaning component 20 in the outward 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 opposite direction to the third direction, thereby switching the cleaning component 20 from the outward position to the inward position.
[0065] For example, the first elastic telescopic member 314 in this embodiment includes a spring. Of course, in other embodiments of this application, the first elastic telescopic member 314 may also be configured as an elastic pad or other structures with elastic function. Any other variations under the concept of this application are within the protection scope of this application.
[0066] Specifically, the guide rod 311 guides 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 limiting the movement trajectory of the cleaning component 20 and making the movement of the cleaning component 20 more stable and controllable. At the same time, the guide rod 311 serves as the mounting support structure for the first elastic telescopic member 314, ensuring that the first elastic telescopic member 314 can function normally. The overall structure is simple, stable, and can reliably guide the movement of the first slider 312, reducing the swaying and deviation of the slider during movement, and improving the accuracy and reliability of the movement of the entire cleaning component 20. The first elastic telescopic member 314 can automatically provide restoring force to the cleaning component 20, realizing the automatic switching of the position of the cleaning component 20 without the need for an additional power device to achieve the position switching of the cleaning component 20. At the same time, the first elastic telescopic member 314 has a buffering effect, which can effectively reduce the impact force when the cleaning component 20 collides with obstacles, thereby protecting the cleaning component 20 and other related components from damage and effectively improving the service life and reliability of the cleaning device.
[0067] In other words, in this embodiment, the position of the cleaning component 20 can be flexibly switched through the cooperation of the guide rod 311, the first slider 312, and the first elastic telescopic member 314. When the cleaning device is in the initial state, the first elastic telescopic member 314 is in a stretched state, which can apply elastic force to the first slider 312, causing the first slider 312 to slide along the third direction on the guide rod 311, thereby driving the cleaning component 20 to be in an outward expansion position, so as to maximize the cleaning range during normal operation. When the cleaning component 20 collides with an obstacle, the cleaning component 20 drives the first slider 312 to slide in the opposite direction to the third direction along the length of the guide rod 311, thereby compressing the first elastic telescopic member 314 and causing the cleaning component 20 to switch from the outward expansion position to the inward contraction position, so that the cleaning component 20 fits against the wall for cleaning, so that there are no dead corners in the cleaning device, effectively improving the cleaning effect of the cleaning device. At the same time, it can also avoid excessive collision between the cleaning component 20 and the obstacle and damage, thus extending the service life of the cleaning component 20 to a certain extent.
[0068] Optionally, in this embodiment, the first fixed end 3111 and the water tank 40 can be connected by snap-fit, welding or screw connection. This configuration makes the structure stable and reliable and easy to process.
[0069] Further, see Figure 5 As shown, the guide rod 311 in this embodiment also has a first free end 3112. The first free end 3112 is located at the 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 in a first direction or a second direction. The bottom of the water tank 40 is provided with a first recess 11. The first recess 11 is recessed from the bottom of the water tank 40 toward the inner side of the water tank 40 and extends in a third direction. The first recess 11 is provided with a first switching component 31, and a limiting groove 111 is provided on the side of the first recess 11 near the first free end 3112. The first free end 3112 is located in the limiting groove 111.
[0070] Specifically, the first recess 11 provides installation space for the first switching component 31. Since the first recess 11 is recessed from the bottom of the water tank 40 towards its inner side, when the first switching component 31 is installed within the first recess 11, it will not protrude from the bottom of the water tank 40, ensuring the flatness of the bottom of the water tank 40. Because the first recess 11 extends along a third direction in this embodiment, when the first switching component 31 is installed within the first recess 11, it can restrict the sliding of the first slider 312, preventing displacement in other directions. Simultaneously, the limiting groove 111 restricts the displacement of the guide rod 311 along a direction perpendicular to its own length, ensuring the stability of the guide rod 311's position during operation. This ensures that the first slider 312 and the connected cleaning component 20 can reciprocate strictly along the length direction of the guide rod 311, avoiding deviation or wobbling, and making the movement of the cleaning component 20 more precise and stable. In addition, the setting of the limiting groove 111 can share some of the force borne by the guide rod 311, especially the lateral force generated during the movement of the cleaning component 20. By limiting the first free end 3112 through the constraint of the limiting groove 111, the overall support stability of the guide rod 311 is enhanced, and the guide rod 311 is prevented from bending or deforming due to uneven force, effectively ensuring the normal operation of the first switching component 31.
[0071] Further, see Figures 5 to 6As shown, the second switching component 32 in this embodiment includes a guide rocker arm 321, a second slider 322, and a second elastic telescopic member 324. Specifically, the guide rocker arm 321 is disposed on the water tank 40 and extends along a third direction, and the guide rocker arm 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, and the second free end 3212 is located at the end of the guide rocker arm 321 away from the second fixed end 3211, and the second free end 3212 can swing around the second fixed end 3211 in a first direction or a second direction; the second slider 322 has a second guide hole 323, the second slider 322 is sleeved on the guide rocker arm 321 through the second guide hole 323 and can slide back and forth along the length direction of the guide rocker arm 321, and the second slider 322 is connected to the cleaning component 20; the second elastic telescopic member 324 is sleeved on the guide rocker arm 321 and is located at the second fixed end 3211 and the second slider 3212. Between blocks 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 a 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 opposite direction to the third direction, so that the second elastic telescopic member 324 is in the contracted state and the cleaning component 20 switches from the outward expansion position to the inward contraction position; during the process of the second switching component 32 being forcefully retracted, the guide rocker arm 321 can drive the cleaning component 20 to swing along the first direction or the second direction.
[0072] For example, the second elastic telescopic member 324 in this embodiment includes a spring. Of course, in other embodiments of this application, the second elastic telescopic member 324 may also be configured as an elastic pad or other structures with elastic function. Any other variations under the concept of this application are within the protection scope of this application.
[0073] Specifically, the guide rocker arm 321 provides a sliding track for the second slider 322, ensuring that the second slider 322 can reciprocate along the length of the guide rocker arm 321. Simultaneously, as part of the structure, it supports the second slider 322 and the connected cleaning assembly 20. Meanwhile, the guide rocker arm 321 can rotate around the second fixed end 3211 in either a first or second direction. This allows the cleaning assembly 20 to not only perform linear reciprocating motion but also change its angle with the swing of the guide rocker arm 321, thereby adjusting the cleaning direction and cleaning range of the cleaning assembly 20. The second slider 322 connects the cleaning assembly 20 and the guide rocker arm 321, thus allowing the guide rocker arm to... The swing of the rod 321 and its sliding along the length of the guide rod 321 are transmitted to the cleaning component 20, thereby changing the position of the cleaning component 20 in the third direction to adapt to different cleaning needs. The second elastic telescopic member 324 can automatically provide a restoring force to the cleaning component 20, realizing the automatic switching of the position of the cleaning component 20 without the need for an additional power device to achieve the position switching of the cleaning component 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 component 20 collides with obstacles, thereby protecting the cleaning component 20 and other related components from damage and effectively improving the service life and reliability of the cleaning device.
[0074] In other words, in this embodiment, the position of the cleaning component 20 can be flexibly switched through the cooperation of the guide rocker 321, the second slider 322, and the second elastic telescopic member 324. When the cleaning device is in the initial state, the second elastic telescopic member 324 is in a stretched state, which can apply elastic force to the second slider 322, causing the second slider 322 to slide along the third direction on the guide rocker 321, thereby driving the cleaning component 20 to be in an outward expansion position, so as to maximize the cleaning range during normal operation. When the cleaning component 20 collides with an obstacle, the cleaning component 20 drives the second slider 322 to slide in the opposite direction to the third direction along the length of the guide rocker 321, thereby compressing the second elastic telescopic member 324 and causing the cleaning component 20 to switch from the outward expansion position to the inward contraction position, so that the cleaning component 20 fits against the wall for cleaning, so that there are no dead corners in the cleaning device, effectively improving the cleaning effect of the cleaning device. At the same time, it can also avoid excessive collision between the cleaning component 20 and the obstacle and damage, thus extending the service life of the cleaning component 20 to a certain extent.
[0075] It is worth noting that, since the second free end 3212 in this embodiment is not connected to the water tank 40, when the second slider 322 slides on the guide rocker arm 321 in the direction opposite to the third direction, the guide rocker arm 321 will rotate around the second fixed end 3211 as the rotation center in the first direction or the second direction.
[0076] Optionally, in this embodiment, the second fixed end 3211 and the water tank 40 can be connected by snap-fit, welding or screw connection. This configuration makes the structure stable and reliable and easy to process.
[0077] Further, see Figures 5 to 6 As shown, in this embodiment, the bottom of the water tank 40 is provided with a second recess 12, and a second switching component 32 is provided in the second recess 12. When the cleaning device is in the initial state, the second switching component 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. The first stop bar 13 extends along a first direction. When the guide rocker arm 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. The second stop bar 14 extends along a second direction. When the guide rocker arm 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 rocker arm 321 in the first direction, ensuring that the guide rocker arm 321 can only move within the range limited by the first stop bar 13, thus guaranteeing the accuracy and stability of the movement; similarly, the second stop bar 14 provides guidance and limitation for the rotation of the guide rocker arm 321 in the second direction, ensuring that the guide rocker arm 321 can only move within the range limited by the second stop bar 14, thus guaranteeing the accuracy and stability of the movement. Meanwhile, when the guide rocker arm 321 rotates along the first or 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. The second elastic telescopic member 324 can store energy after being compressed and can release energy when needed, thereby playing a buffering and shock absorption role. For example, when the rotational movement of the guide rocker arm 321 suddenly stops or is impacted by an external force, it can reduce the impact force on the entire cleaning device and extend the service life of the cleaning device. In addition, the compression of the second elastic telescopic member 324 can also generate a restoring force. When the rotational external force of the guide rocker arm 321 disappears, the second elastic telescopic member 324 will rely on its own restoring force to make the guide rocker arm 321 return to the initial position. That is to say, the second elastic telescopic member 324 also provides power for the reset of the guide rocker arm 321.
[0079] In addition, in this embodiment, the second recess 12 is divided into a first rotation space 101 and a second rotation space 102 by the second switching component 32. This space separation design allows moving parts and functional parts in different directions to work in their own 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] Further, see Figures 5 to 6 As shown, in this embodiment, the first rotation space 101 is also provided with a first stop edge 15 and a first extension space 16. When the cleaning device is in the initial state, the first stop edge 15 and the second switching component 32 surround to form the first rotation space 101. The first extension space 16 is located on the first stop edge 15 and extends from the first stop edge 15 in a direction away from the first rotation space 101. The first extension space 16 is connected to the first rotation space 101. When the guide rocker arm 321 rotates to the first predetermined angle along the first direction, the guide rocker arm 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 guide rocker arm 321 rotates to a first predetermined angle along the first direction, it abuts against the first stop edge 15. This clearly defines the rotation angle range of the guide rocker arm 321 in the first direction, ensuring that it can only rotate within a specific angle. This achieves precise positioning and guarantees that the movement of the guide rocker arm 321 during the operation of the cleaning device meets the design requirements, avoiding component damage or functional failure that may result from excessive rotation. Simultaneously, the first extension space 16 extends from the first stop edge 15 in a direction away from the first rotation space 101 and communicates with the first rotation space 101. When the guide rocker arm 321 rotates to the first predetermined angle, the second slider 322 can be located within the first extension space 16. This provides additional movement space for the second slider 322 during the rotation of the guide rocker arm 321, allowing it to move accordingly with the movement of the guide rocker arm 321. This ensures smooth coordinated movement between the second slider 322, the guide rocker arm 321, and other related components.
[0082] Further, see Figures 5 to 6As shown, in this embodiment, a second stop edge 17 and a second extension space 18 are also provided in the second rotation space 102. When the cleaning device is in the initial state, the second stop edge 17 and the second switching component 32 surround to form the second rotation space 102. The second extension space 18 is located on the second stop edge 17 and extends from the second stop edge 17 in a direction away from the second rotation space 102. The second extension space 18 is connected to the second rotation space 102. When the guide rocker arm 321 rotates to the second predetermined angle along the second direction, the guide rocker arm 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 guide rocker arm 321 rotates to the second predetermined angle along the second direction, it abuts against the second stop edge 17. This clearly defines the rotation angle range of the guide rocker arm 321 in the second direction, ensuring that it can only rotate within a specific angle. This achieves precise positioning and guarantees that the movement of the guide rocker arm 321 during the operation of the cleaning device meets the design requirements, avoiding component damage or functional failure that may result from excessive rotation. Simultaneously, 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 guide rocker arm 321 rotates to the second predetermined angle, the second slider 322 can be located within the second extension space 18. This provides additional movement space for the second slider 322 during the rotation of the guide rocker arm 321, allowing it to move accordingly with the movement of the guide rocker arm 321. This ensures smooth coordinated movement between the second slider 322, the guide rocker arm 321, and other related components.
[0084] Furthermore, in this embodiment, the first predetermined angle A satisfies the relationship: 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 guide rocker arm 321 is too large, which may cause the second slider 322 to excessively compress the second elastic telescopic member 324, exceeding the bearing capacity of the second elastic telescopic member 324. This could lead to premature fatigue and damage of the second elastic telescopic member 324, resulting in the loss of its buffering and reset functions. At the same time, the impact force between the guide rocker arm 321 and the first stop edge 15 will also increase due to the large-angle rotation, which may cause wear, deformation, or even breakage of the first stop edge 15 or the guide rocker arm 321 itself, affecting the normal operation and service life of the cleaning device.
[0086] Furthermore, in this embodiment, the second predetermined angle B 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 included angle B is greater than 65°, the rotation angle of the guide rocker arm 321 is too large, which may cause the second slider 322 to excessively compress the second elastic telescopic member 324, exceeding the bearing capacity of the second elastic telescopic member 324. This could lead to premature fatigue and damage of the second elastic telescopic member 324, resulting in the loss of its buffering and reset functions. At the same time, the impact force between the guide rocker arm 321 and the second stop edge 17 will also increase due to the large-angle rotation, which may cause wear, deformation, or even breakage of the second stop edge 17 or the guide rocker arm 321 itself, 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 component (not shown in the figures). The support plate 21 has a first connecting post 22 and a second connecting post 23 spaced apart on the side near the water tank 40. The first connecting post 22 has a first clearance notch 221, and the second connecting post 23 has a second clearance notch 231. The cleaning component is located 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. The first slider 312 has a first clearance channel 315 through which the first connecting post 22 passes. The inner wall of the first clearance channel 315 is provided with a first clearance notch 222. The limiting member 316 has a second limiting member 222 on the outer wall of the first connecting post 22. The first connecting post 22 passes through the first clearance 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 clearance notch 221. The second slider 322 has a second clearance channel 325 through which the second connecting post 23 passes. The inner wall of the second clearance channel 325 has a third limiting member 326, and the outer wall of the second connecting post 23 has a fourth limiting member 232. The second connecting post 23 passes through the second clearance channel 325 so that the fourth limiting member 232 is engaged with the third limiting member 326, and the guide rocker 321 is located at the second clearance notch 231.
[0089] For example, the cleaning component in this embodiment can be a mop or a brush.
[0090] Specifically, in this embodiment, the first connecting post 22 passes through the first clearance channel 315 of the first slider 312 to allow the second limiting member 222 to engage with the first limiting member 316, and the second connecting post 23 passes through the second clearance channel 325 of the second slider 322 to allow the fourth limiting member 232 to engage with the third limiting member 326. This arrangement ensures accurate connection between the support plate 21 of the cleaning component 20 and the first switching component 31 and the second switching component 32, fixing the relative positions of the components and preventing arbitrary displacement or shaking during operation. Simultaneously, the first clearance notch 221 of the first connecting post 22 cooperates with the guide rod 311, and the second clearance notch 231 of the second connecting post 23 cooperates with the guide swing rod 321, providing specific movement space and guiding paths for the guide rod 311 and the guide swing rod 321, enabling them to move along specific trajectories while avoiding interference with the connecting post and other components, ensuring smooth movement of each component.
[0091] Further, see Figure 8 as well as Figure 10 As shown, in this embodiment, the first limiting member 316 includes a first limiting protrusion 317, which protrudes from the inner wall surface of the first clearance channel 315 and extends circumferentially along the first clearance channel 315. The second limiting member 222 includes a second limiting protrusion 223, which protrudes from the outer wall surface of the first connecting post 22 and extends circumferentially along the first connecting post 22. The extension length of the first limiting protrusion 317 is greater than the extension length of the second limiting protrusion 223, so that the second limiting protrusion 223 can move along the extension direction of the first limiting protrusion 317.
[0092] Specifically, the first limiting protrusion 317 and the second limiting protrusion 223 extend circumferentially. They cooperate to restrict the radial relative movement between the first connecting post 22 and the first clearance channel 315, ensuring that the first connecting post 22 does not excessively sway or shift within the first clearance channel 315, thus maintaining a relatively fixed positional relationship between the cleaning assembly 20 and the first switching assembly 31 in the radial direction. Simultaneously, since the extension length of the first limiting protrusion 317 is greater than the extension length of the second limiting protrusion 223, the second limiting protrusion 223 can move in the extension direction of the first limiting protrusion 317. This provides guidance for the axial movement of the first connecting post 22 relative to the first slider 312, allowing the first connecting post 22 to move within a specific axial range, realizing the relative axial movement between the cleaning assembly 20 and the first switching assembly 31, thereby facilitating the rotation of the cleaning assembly 20 along the first or second direction.
[0093] Further, see Figures 8 to 9As shown, in this embodiment, the third limiting member 326 includes a third limiting protrusion 327, which protrudes from the inner wall of the second clearance channel 325 and extends circumferentially along the second clearance channel 325. The fourth limiting member 232 includes a fourth limiting protrusion 233, which protrudes from the outer wall of the second connecting post 23 and extends circumferentially along the second connecting post 23. The extension length of the third limiting protrusion 327 is greater than the extension length of the fourth limiting protrusion 233, so that the fourth limiting protrusion 233 can move along the extension direction of the third limiting protrusion 327.
[0094] Specifically, the third limiting ridge 327 and the fourth limiting ridge 233 extend circumferentially. They cooperate to restrict the radial relative movement between the second connecting post 23 and the second clearance channel 325, ensuring that the second connecting post 23 does not excessively sway or shift within the second clearance channel 325, thus maintaining a relatively fixed positional relationship between the cleaning assembly 20 and the second switching assembly 32 in the radial direction. Simultaneously, since the extension length of the third limiting ridge 327 is greater than that of the fourth limiting ridge 233, the fourth limiting ridge 233 can move in the extension direction of the third limiting ridge 327. This guides the axial movement of the second connecting post 23 relative to the second slider 322, allowing the second connecting post 23 to move within a specific axial range, realizing the relative axial movement between the cleaning assembly 20 and the second switching assembly 32, thereby facilitating the rotation of the cleaning assembly 20 along the first or second direction.
[0095] As can be seen from the above embodiments, this application provides a first switching component 31 and a second switching component 32 on the body 10. The first slider 312 of the first switching component 31 is connected to the first connecting post 22 of the support plate 21, and the second slider 322 of the second switching component 32 is connected to the second connecting post 23 of the support plate 21. In this way, when the cleaning component 20 collides with an obstacle, it can drive the cleaning component 20 to rotate in the first or second direction, thereby realizing the multi-directional collision retraction of the cleaning component 20. This allows the cleaning component 20 to cover the corner blind areas in all directions, effectively improving the cleaning coverage of the cleaning device.
[0096] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0097] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0098] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
