[0003] This application provides a cleaning device to improve the technical problem of short service life of cleaning components.

[0004] To address the aforementioned technical problems, this application provides a cleaning device comprising a body, a cleaning component, and an anti-collision component. The cleaning component is disposed on the body and has a first cleaning state and a second cleaning state. When the cleaning component is in the first cleaning state, it protrudes at least partially from the body. The anti-collision component is located on the cleaning component. When the cleaning component is in the first cleaning state, the anti-collision component is configured to detect whether there is an obstacle in front of the cleaning component. When there is an obstacle in front of the cleaning component, the cleaning component moves from the first cleaning state to the second cleaning state.

[0005] In one embodiment, the anti-collision component is located on the front side or end of the cleaning component.

[0006] In one embodiment, the anti-collision component is disposed on the body and located at the front end face of the cleaning component. The orientation of the front end face is consistent with the travel direction of the body. The cleaning component is movably connected to the body along a first direction, which is perpendicular to the travel direction. When the anti-collision component is subjected to a force opposite to the travel direction, it indirectly or directly triggers the cleaning component to move from the first cleaning state to the second cleaning state along the first direction.

[0007] In one embodiment, the anti-collision component includes: an anti-collision support, the first end of which is rotatably connected to the body, and the second end of which is used to abut against the cleaning component; and a first elastic member, one end of which is connected to the body, and the other end of which is connected to the anti-collision support; wherein, when the cleaning component is in the first cleaning state, the first elastic member is in a stretched state, and the second end of the anti-collision support abuts against the cleaning component; when the cleaning component is in the second cleaning state, the first elastic member is in a free state, and the second end of the anti-collision support is separated from the cleaning component.

[0008] In one embodiment, the anti-collision assembly further includes: a sensor disposed on the side of the anti-collision support opposite to the body; a second elastic member disposed on the side of the sensor opposite to the anti-collision support, with one end connected to the sensor; and an anti-collision plate disposed on the side of the second elastic member opposite to the sensor, rotatably connected to the body, and connected to the other end of the second elastic member; wherein the anti-collision plate is configured to compress the second elastic member when subjected to the applied force to trigger the sensor, and when the sensor is triggered, the cleaning assembly resets towards the body along the first direction.

[0009] In one embodiment, the end of the anti-collision plate away from the body extends toward the anti-collision support to form an abutment portion, the abutment portion being spaced apart from the anti-collision support. When the anti-collision plate is subjected to the force, the abutment portion abuts against the anti-collision support, so that the anti-collision support drives the cleaning component to move along the first direction from the first cleaning state to the second cleaning state.

[0010] In one embodiment, the sensor includes a microswitch.

[0011] In one embodiment, the cleaning device further includes a lifting component connected to the body and slidably connected to the cleaning component to allow the cleaning component to move relative to the body along a second direction; wherein the second direction is perpendicular to the first direction.

[0012] In one embodiment, the cleaning device further includes a third elastic member disposed between the cleaning component and the body, with its two ends respectively abutting against the outer side wall of the cleaning component and the body.

[0013] In one embodiment, the body includes a first sidewall and a second sidewall connected in a third direction. The second sidewall is close to the cleaning component and recessed relative to the first sidewall to form a receiving groove. When the cleaning component is in a second cleaning state, the anti-collision component is located in the receiving groove, wherein the third direction is perpendicular to the first direction.

[0014] In one embodiment, when the cleaning component is in the second cleaning state, in the third direction, the outer side of the anti-collision component is flush with the first sidewall, away from the body.

[0015] In one embodiment, when the cleaning component is in the first cleaning state, the angle between the anti-collision support and the body is an acute angle.

[0016] The beneficial effects of this application are as follows: The cleaning component of the cleaning device is disposed within the main body and is used to clean the surface to be cleaned. The cleaning component has a first cleaning state and a second cleaning state. When the cleaning component is in the first cleaning state, it protrudes at least partially from the main body; when the cleaning component is in the second cleaning state, it is located within the main body. When the cleaning component is in the first cleaning state, the portion protruding from the main body is closer to the edge of obstacles such as walls or table legs than to the edge of the main body, enabling the cleaning device to achieve edge-to-edge cleaning.

[0026] Automated cleaning equipment is a type of automated device used for cleaning floors, primarily in homes, offices, and commercial spaces. It automatically performs tasks such as vacuuming and mopping through built-in sensors, motors, and cleaning systems, reducing the workload of manual cleaning. Existing automated cleaning equipment mainly uses radar or side sensors to detect obstacles and avoid them. However, when the environment is complex, the accuracy of radar or side sensors decreases, leading to collisions and reducing the lifespan of the cleaning equipment.

[0027] To address the aforementioned technical problems, this application provides a cleaning device that can improve collision performance and extend service life. The cleaning device of this application can be a cleaning device with a roller brush cleaning function, or a cleaning device with cleaning functions such as a tracked mop, a rotary mop, or a side brush. The cleaning device can have one or more cleaning functions such as washing, mopping, and sweeping, and is not limited thereto. The cleaning device can be self-moving or moved by hand, and is not limited thereto.

[0028] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the cleaning component provided in this application in a first state of one embodiment. Figure 2 This is a schematic diagram of an embodiment of the cleaning component provided in this application in its reset state. The cleaning device 10 includes a body 110, a cleaning component 120, and an anti-collision component 130. The movement of the body 110 can be considered as the movement of the cleaning device 10. The cleaning component 120 is located in the vertical direction of the body 110, and the anti-collision component 130 is located in the horizontal direction of the body 110. The forward and backward direction of the body 110 is consistent with its forward or backward movement. In the use state, the cleaning component 120 is located at the bottom of the body 110.

[0029] In this embodiment, the cleaning component 120 is disposed on the body 110 and is used to clean the surface to be cleaned. The cleaning component 120 has a first cleaning state and a second cleaning state. When the cleaning component 120 is in the first cleaning state, the cleaning component 120 protrudes at least partially from the body 110; when the cleaning component 120 is in the second cleaning state, the cleaning component 120 is located inside the body 110. When the cleaning component 120 is in the first cleaning state, the portion of the cleaning component 120 protruding from the body 110 is closer to the edge of obstacles such as walls or table legs than the edge of the body 110, enabling the cleaning device 10 to achieve edge cleaning function.

[0030] When the cleaning component 120 is in the first cleaning state, the cleaning component 120 at least partially protrudes from the body 110. This protrusion can be along the left-right direction of the body 110, or along the front-back direction of the body 110, or at a certain angle to the left-right direction; there are no limitations on this. The portion of the cleaning component 120 protruding from the body 110 can cover part of the edge of the body 110, or cover all the edges of the body 110; there are no limitations on this either. For example, the cleaning assembly 120 includes a roller brush, the axis of which is parallel to the left-right direction of the body. When the cleaning assembly 120 is in a first cleaning state, the roller brush can protrude from the body 110 in the left-right direction, or in other words, protrude from the body in the first direction X; or, the roller brush can protrude from the body 110 in the front-back direction, or in other words, protrude from the body in the second direction Y; or, the cleaning assembly 120 includes a side brush, which protrudes from the body 110 in the first cleaning state along the first direction X; the cleaning assembly 120 may also include both a roller brush and a side brush, wherein the side brush is located at one end of the roller brush in its axial direction, and in the first cleaning state, the side brush and the roller brush can independently protrude from the body 110 in the first direction X.

[0031] When the cleaning component 120 is in the first cleaning state, the anti-collision component 130 is configured to detect whether there is an obstacle in front of the cleaning component 120. When there is an obstacle in front of the cleaning component 120, the cleaning component 120 moves from the first cleaning state to the second cleaning state.

[0032] It is known that in the first cleaning state, the cleaning component 120 protrudes at least partially from the body 110. Since the anti-collision component 130 is located at the front end face A of the cleaning component 120, when the anti-collision component 130 detects an obstacle in front of the cleaning component 120, the cleaning component 120 moves from the first cleaning state to the second cleaning state, so that the cleaning component 120 can avoid the obstacle, reduce the probability of the cleaning component colliding with the obstacle, thereby reducing the probability of damage to the cleaning component 120, extending the service life of the cleaning component 120, and thus extending the service life of the cleaning device 10, while improving the user experience.

[0033] In one embodiment, the anti-collision component 130 is disposed on the body 110 and is located on the front end face A of the cleaning component 120. The orientation of the front end face A is consistent with the travel direction of the body 110. Therefore, when the cleaning device 10 does not detect an obstacle on the front end face, the obstacle will first collide with the anti-collision component 130. Thus, the anti-collision component 130 can protect the cleaning component 120, reduce the probability of damage to the cleaning component 120, extend the service life of the cleaning component 120, and thus extend the service life of the cleaning device 10, while improving the user experience.

[0034] In one embodiment, the anti-collision component is disposed on the body, and the anti-collision component 130 is located at the front end face A of the cleaning component 120. The orientation of the front end face A is consistent with the travel direction of the body 110. The cleaning component 120 is movably connected to the body 110 along a first direction X, which is perpendicular to the travel direction. The cleaning component 120 can move from a first cleaning state to a second cleaning state along the first direction X, or in other words, the cleaning component 120 moves outward relative to the body 110 to the first cleaning state along the first direction X, or moves inward relative to the body 110 to the second cleaning state. When the anti-collision component 130 is subjected to a force opposite to the travel direction, it indirectly or directly triggers the cleaning component 120 to reset towards the body 110 along the first direction X. Understandably, when the cleaning device 10 is operating in the edge cleaning state, the cleaning component 120 protrudes beyond the body 110. When the anti-collision component 130 is subjected to a force opposite to the direction of travel, the anti-collision component 130 can drive the cleaning component 120 to reset towards the body 110 along the first direction X; or the anti-collision component 130 can feed back an obstacle signal to the controller of the cleaning device 10, and the controller can control the cleaning component 120 to reset towards the body 110 along the first direction X based on the obstacle signal. It is worth noting that regardless of whether the anti-collision component 130 directly or indirectly triggers the cleaning component 120 to reset towards the body 110 along the first direction X, the cleaning component 120 can avoid obstacles, further reducing the probability of damage to the cleaning component 120, thereby further extending the service life of the cleaning component 120, and thus extending the service life of the cleaning device 10 and enhancing the user experience.

[0035] In other embodiments, the anti-collision component may also be located on the front side or end of the cleaning component, which can more directly protect the cleaning component.

[0036] In some embodiments, when the cleaning component is in the second cleaning state, the cleaning component is located within the body, and the anti-collision component may be located within the body.

[0037] In one embodiment, see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of an embodiment of the anti-collision component provided in this application in its first state. Figure 4 This is a schematic diagram of an embodiment of the anti-collision component provided in this application in its reset state. The anti-collision component 130 includes an anti-collision support 131 and a first elastic member 132. The first end of the anti-collision support 131 is rotatably connected to the body 110, and the second end of the anti-collision support 131 is used to abut against the cleaning component 120. One end of the first elastic member 132 is connected to the body 110, and the other end of the first elastic member 132 is connected to the anti-collision support 131. In the edge-cleaning state, the first elastic element 132 is in a stretched state, and the second end of the anti-collision support 131 abuts against the cleaning component 120. At this time, the anti-collision support 131 is pushed out of the body 110 by the cleaning component 120. When the cleaning device 10 encounters an obstacle in front of the travel direction, the obstacle collides with the anti-collision support 131, triggering the cleaning component 120 to reset along the first direction X toward the body 110 to avoid the obstacle. At the same time, the anti-collision support 131 rebounds inward toward the body 110 under the action of the collision force and the first elastic element 132, which can buffer the collision force and avoid the obstacle, reduce the damage to the anti-collision component 130, and enhance the reliability of the anti-collision component 130. In the reset state, the first elastic element 132 is in a natural state, and the second end of the anti-collision support 131 is separated from the cleaning component 120.

[0038] In one embodiment, the cleaning component 120 may be movable via a slider and a fourth elastic element, which is not limited herein.

[0039] In one embodiment, in the edge cleaning state, the angle between the anti-collision support 131 and the body 110 is an acute angle. The acute angle setting makes it easy for the first elastic element 132 to drive the anti-collision support 131 back to its natural state, thereby enhancing the reliability of the anti-collision component 130.

[0040] In one embodiment, the anti-collision assembly 130 further includes a sensor 133, a second elastic element 134, and an anti-collision plate 135. The sensor 133 is located on the side of the anti-collision support 131 opposite to the body 110. The second elastic element 134 is located on the side of the sensor 133 opposite to the anti-collision support 131, and one end of the second elastic element 134 is connected to the sensor 133. The anti-collision plate 135 is located on the side of the second elastic element 134 opposite to the sensor 133, rotatably connected to the body 110, and connected to the other end of the second elastic element 134. The anti-collision plate 135 is configured to compress the second elastic element 134 when subjected to a force, and the second elastic element 134 transmits the force to the sensor 133, triggering the sensor 133. When the sensor 133 is triggered, the cleaning assembly 120 is triggered to reset towards the body 110 along the first direction X. For example, when the sensor 133 is triggered, the controller of the cleaning device 10 controls the cleaning assembly 120 to reset towards the body 110 along the first direction X.

[0041] In one embodiment, the end of the anti-collision plate 135 away from the main body 110 extends toward the anti-collision support 131 to form an abutment portion (not shown in the figure), and the abutment portion is spaced apart from the anti-collision support 131. When the anti-collision plate 135 is subjected to a force opposite to the direction of travel, the anti-collision plate 135 triggers the sensor 133, and the abutment portion abuts against the anti-collision support 131. The abutment portion transmits the force to the anti-collision support 131, so that the anti-collision support 131, under the action of the force of the obstacle and the restoring force of the first elastic member 132, drives the cleaning component 120 to reset along the first direction X toward the main body 110. Thus, the cleaning component 120 can avoid the obstacle in time, enhancing the obstacle avoidance capability of the cleaning device 10.

[0042] In one embodiment, the cleaning assembly 120 includes a housing 121. A protrusion 1213 is formed on the outer wall of the housing 121 near the anti-collision assembly 130, and the protrusion 1213 abuts against the anti-collision support 131. In a first state, the protrusion 1213 abuts against the anti-collision support 131, and the anti-collision assembly 130 is pushed out. When the anti-collision plate 135 is subjected to a force opposite to the direction of travel, the anti-collision plate 135 compresses the second spring trigger sensor 133, and then the abutment portion abuts against the anti-collision support 131. The force exerted by the anti-collision support 131 on the protrusion 1213 increases, thereby causing the housing 121 to reset inward toward the body 110 along the first direction X to avoid obstacles. In this embodiment, the protrusion 1213 is provided on the housing 121, and the anti-collision support 131 drives the cleaning assembly 120 to reset inward toward the body 110 along the first direction X through the protrusion 1213. The structure is simple and easy to implement.

[0043] In one embodiment, sensor 133 includes a microswitch. In other embodiments, sensor 133 may also be a ranging sensor 133, which can indicate whether an obstacle is detected by measuring changes in the distance between the bumper 135 and the sensor 133.

[0044] In one embodiment, the first direction X corresponds to the left-right direction of the cleaning device 10, or the body 110, and the third direction Z corresponds to the front-back direction of the body 110, which is perpendicular to the first direction X. The body 110 includes a first sidewall 111 and a second sidewall 112 connected in the third direction Z. The second sidewall 112 is recessed relative to the first sidewall 111 at one end of the cleaning component 120 in the first direction X, forming a receiving groove 113. The anti-collision component 130 is located within the receiving groove 113 when in the reset state. In this embodiment, the anti-collision component 130 is housed in the receiving groove 113 in the reset state, which reduces the size of the cleaning device 10 in the first direction X and improves the aesthetics of the cleaning device 10.

[0045] In one embodiment, when the cleaning component 120 is in the reset state, in the third direction Z, the outer side of the anti-collision component 130 is flush with the first sidewall 111, away from the main body 110. In this embodiment, the anti-collision component 130 is housed in the receiving groove 113 in the reset state, and the outer side of the anti-collision component 130 is flush with the first sidewall 111, thus maintaining the original size of the cleaning device 10.

[0046] In one embodiment, see Figure 5 , Figure 5 This is a schematic diagram of a cleaning device according to an embodiment of the present application. The cleaning device 10 further includes a lifting component 140, which is disposed on the body 110 and slidably connected to the cleaning component 120, so that the cleaning component 120 can move relative to the body 110 along a second direction Y. The second direction Y is perpendicular to the first direction X and parallel to the vertical direction of the body 110. That is, the cleaning component 120 of this application can move relative to the body 110 along the vertical direction of the body 110 via the lifting component 140.

[0047] In one embodiment, the cleaning device 10 further includes a third elastic member 150, which is disposed between the cleaning component 120 and the body 110. Both ends of the third elastic member 150 abut against the outer wall of the cleaning component 120 and the body 110, respectively. Understandably, the third elastic member 150 is located between the cleaning component 120 and the body 110, and abuts against both the body 110 and the cleaning component 120. At this time, the third elastic member 150 is in a compressed state, which increases the force between the cleaning component 120 and the surface to be cleaned, thereby enhancing the cleaning effect of the cleaning component 120 on the surface to be cleaned.

[0048] In one embodiment, the cleaning assembly 120 includes a housing 121, with a guide post 1211 formed on the outer side wall of the housing 121. The third elastic member 150 includes a spring post, which is sleeved on the outer periphery of the guide post 1211, and its two ends abut against the outer side wall of the housing 121 and the body 110, respectively. It is worth noting that the spring post is always in a compressed state.

[0049] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
