Description

Technical Field

[0001] This invention belongs to the technical field of cleaning equipment, and specifically relates to a cleaning device. Background Technology

[0002] With the continuous improvement of living conditions and technological level, cleaning equipment has the advantages of being easy to use and having good cleaning effect. Therefore, cleaning equipment has gradually begun to replace manual cleaning and has appeared widely in life and work.

[0003] However, current cleaning equipment has limited functionality. Some cleaning equipment can only sweep, while others can only mop. When switching between sweeping and mopping modes, the cleaning components need to be manually replaced. Alternatively, during the cleaning process, when a cleaning component gets dirty, it needs to be manually replaced with another component to continue sweeping or mopping. In other words, the cleaning components need to be replaced within the same cleaning mode, but replacing the cleaning components requires manual operation, making the operation complicated, time-consuming, and resulting in a poor user experience.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

The cleaning component includes a mounting frame and at least two first cleaning elements and at least two second cleaning elements alternately arranged on the outer wall of the mounting frame. The first and second cleaning elements are respectively separated from the rotation center of the cleaning component by a first distance and a second distance. A support mechanism is disposed inside the mounting frame and has at least two support arms. The movement of the support arms causes either the first or second cleaning element to be in a cleaning state.

[0012] Optionally, the transmission part is sleeved outside the locking part, and the inner wall of the transmission part is connected to the outer wall of the locking part by threads.

[0013] Optionally, the cleaning device includes a third rotating shaft, the first end of which is connected to the body, a locking part having a sliding hole, and the second end of the third rotating shaft passing through the sliding hole; an elastic element, one end of which is connected to the body, and the other end of which abuts against the locking part, the elastic element providing the locking part with an elastic force to move in the direction of the moving part.

[0014] Optionally, the transmission part is a first helical gear and the locking part is a second helical gear; the transmission part is slidably and rotatably mounted on the machine body; in the switching state, the first helical gear meshes with the second helical gear.

[0015] Optionally, a locking member is provided on the side of the locking part facing the movable part, and the movable part has a mating member for engaging with the locking member. In the switching state, the locking member can engage with the mating member.

[0016] Optionally, both the locking element and the mating element are ratchet structures.

[0017] Optionally, the cleaning equipment also includes a drive assembly, which is mounted on the body and driven by a support mechanism, thereby driving the support mechanism to rotate.

[0018] Optionally, the frame includes a rotating body that is rotatable under the drive of a driving force; a support arm is fixed to the outer end of the rotating body along a direction perpendicular to the rotation axis of the rotating body; a first end cover is fixedly disposed on the first end of the rotating body; a second end cover is distributed on the second end of the rotating body, and the two end covers together form an installation area; the two ends of the support arm along its length are respectively disposed on the first end cover and the second end cover; a movable part is fixed to the rotating body and located within the installation area; a transmission part is disposed on the second end cover; and a locking part is located within the installation area.

[0024] Specifically, when the support arm is used to abut against the first cleaning component, the distance between the rotation center of the first cleaning component and the cleaning assembly is greater than the distance between the rotation center of the second cleaning component and the cleaning assembly; when the support arm is used to abut against the second cleaning component, the distance between the rotation center of the second cleaning component and the cleaning assembly is greater than the distance between the rotation center of the first cleaning component and the cleaning assembly.

[0025] As can be seen from the above, this application uses a support mechanism to rotate the angle so that the support arm of the support mechanism can abut against the first or second cleaning component. This abutment method adjusts the distance between the first and second cleaning components and the rotation center of the cleaning assembly. During use, the cleaning component with a larger distance from the rotation center of the cleaning assembly can effectively clean the surface to be cleaned during rotation. The mounting bracket of this application's cleaning assembly simultaneously provides at least two first cleaning components and at least two second cleaning components, and the support mechanism allows for selective selection of either the first or second cleaning component for cleaning, thus improving versatility. Selecting the first or second cleaning component only requires controlling the rotation angle of the support mechanism, making operation simple. Attached Figure Description

[0055] This invention solves the problems of limited functionality and complex operation of existing cleaning equipment.

[0056] Example 1

[0057] This embodiment provides a cleaning device, such as Figures 1 to 18As shown, the cleaning equipment includes a body, a cleaning component 10, and a support mechanism 20. The cleaning component 10 is movably connected to the body. The cleaning component 10 includes a mounting frame 110 and at least two first cleaning elements 120 and at least two second cleaning elements 130 alternately arranged on the outer wall of the mounting frame 110. The first cleaning elements 120 and the second cleaning elements are respectively separated from the rotation center of the cleaning component by a first distance and a second distance. The support mechanism 20 is adjustablely arranged inside the mounting frame 110. The support mechanism 20 has at least two support arms 210. The multiple support arms 210 are used to abut against the first cleaning elements 120 or the second cleaning elements 130. The support arms 210 move to bring the first cleaning elements 120 or the second cleaning elements 130 into a clean state.

[0058] Specifically, when the support arm 210 is used to abut against the first cleaning component 120, the distance between the rotation center of the first cleaning component 120 and the cleaning assembly 10 is greater than the distance between the rotation center of the second cleaning component 130 and the cleaning assembly 10, the first distance > the second distance, and the first cleaning component 120 is in a cleaning state; when the support arm 210 is used to abut against the second cleaning component 130, the distance between the rotation center of the second cleaning component 130 and the cleaning assembly 10 is greater than the distance between the rotation center of the first cleaning component 120 and the cleaning assembly 10, the second distance > the first distance, and the second cleaning component 130 is in a cleaning state.

[0059] Specifically, this application utilizes the rotation angle of the support mechanism 20 to allow the support arm 210 of the support mechanism 20 to abut against the first cleaning component 120 or the second cleaning component 130. This abutment method with the support arm 210 adjusts the distance between the first cleaning component 120 and the second cleaning component 130 and the rotation center of the cleaning assembly 10. During use of the cleaning assembly 10, cleaning components with a larger distance from the rotation center of the cleaning assembly 10 can clean the surface to be cleaned during rotation, while cleaning components with a smaller distance do not contact the surface to be cleaned during rotation. The mounting bracket 110 of the cleaning assembly 10 of this application simultaneously provides at least two first cleaning components 120 and at least two second cleaning components 130, and the support mechanism 20 allows for selective selection of either the first cleaning component 120 or the second cleaning component 130 for cleaning, thus improving versatility. Selecting either the first cleaning component 120 or the second cleaning component 130 only requires controlling the rotation angle of the support mechanism 20, simplifying operation.

[0060] Furthermore, the first cleaning component 120 includes sweeping bristles. Specifically, the bristles on the surface of the first cleaning component 120 are bristles suitable for sweeping, such as rubber strips. The rubber strips are sweeping bristles used for sweeping to achieve the sweeping effect. The second cleaning component 130 includes wet mop bristles. Specifically, the second cleaning component 130 is a mop cloth. The bristles of the mop cloth are wet mop bristles used for mopping to achieve the sweeping effect.

[0061] Furthermore, an anti-interference seam is provided between adjacent first cleaning component 120 and second cleaning component 130.

[0062] It should be noted that, in order to facilitate the support mechanism 20 switching to abut against the first cleaning component 120 or the second cleaning component 130, the first cleaning component 120 and the second cleaning component 130 are set to similar or the same size, so as to avoid the first cleaning component 120 or the second cleaning component 130 being too large or too small, which would cause interference between the first cleaning component 120 and the second cleaning component 130 during the cleaning process.

[0063] In this embodiment, when cleaning the surface to be cleaned, if sweeping is required, the support mechanism 20 is adjusted so that the distance between the first cleaning component 120 and the rotation center of the cleaning assembly 10 is greater than the distance between the second cleaning component 130 and the rotation center of the cleaning assembly 10. At this time, the first cleaning component 120 remains in contact with the surface to be cleaned, while a gap exists between the second cleaning component 130 and the surface to be cleaned, thus enabling sweeping only of the surface to be cleaned. Similarly, when mopping is required, the support mechanism 20 is adjusted so that the distance between the second cleaning component 130 and the rotation center of the cleaning assembly 10 is greater than the distance between the first cleaning component 120 and the rotation center of the cleaning assembly 10, thus enabling mopping only.

[0064] Furthermore, the support mechanism 20 is rotatably mounted on the mounting frame 110. The support arm 210 has a working state that rotates synchronously with the mounting frame 110, and a switching state that rotates relative to the mounting frame 110. In the working state, the support arm 210 abuts against one of the first cleaning component 120 and the second cleaning component 130, so that the abutting cleaning component is in a clean state. In the switching state, through the rotation of the support mechanism 20, the support arm 210 switches from abutting against one of the first cleaning component 120 and the second cleaning component 130 to abutting against the other of the first cleaning component 120 and the second cleaning component 130, so that the abutting cleaning component is in a clean state.

[0065] When the support arm 210 is in the working state, the support arm 210 abuts against the first cleaning component 120 or the second cleaning component 130 so that the abutted cleaning component is in a clean state to ensure that the cleaning function is performed.

[0066] When it is necessary to switch the cleaning state between the first cleaning component 120 and the second cleaning component 130, the support arm 210 switches between abutting the first cleaning component 120 and the second cleaning component 130 so that the abutted cleaning component enters the cleaning state.

[0067] like Figures 7 to 12As shown, the mounting frame 110 includes a closed-loop deformable skeleton. A plurality of first cleaning elements 120 and a plurality of second cleaning elements 130 are alternately arranged on the outer peripheral surface of the skeleton. The outer wall surface of the support arm 210 is distributed on the outer peripheral surface of the same cylinder, and the other parts of the support mechanism 20 fall inside the cylinder. The support mechanism 20 rotates to force the skeleton to deform so that the support arm 210 abuts against the first cleaning element 120 or the second cleaning element 130.

[0068] Specifically, multiple first cleaning components 120 and multiple second cleaning components 130 are arranged on the mounting frame 110 to move synchronously with the mounting frame 110. The mounting frame 110 adopts a deformable frame so that when the support arm 210 rotates relative to the mounting frame 110, the support arm 210 can support different positions of the mounting frame 110, thereby abutting against the first cleaning component 120 or the second cleaning component 130.

[0069] Furthermore, the support end of the support arm 210 has a support protrusion 211, which abuts against the inner surface of the flexible frame, and the abutment surface of the support protrusion 211 is an arched arc surface. The support arm 210 abuts against the flexible frame to abut against the corresponding cleaning component on the flexible frame. The arched arc surface increases the contact area, and when the support arm 210 switches its position to abut against the mounting bracket 110, the arched arc surface reduces the friction between the mounting bracket 110 and the support arm 210, improving rotation efficiency.

[0070] In this embodiment, the size of the support protrusion 211 can be adaptively set according to the size of the first cleaning member 120 and the second cleaning member 130, so that when the support protrusion 211 abuts against the first cleaning member 120 or the second cleaning member 130, it can abut against the entire area of ​​the first cleaning member 120 or the second cleaning member 130.

[0071] like Figure 3a , 3b to Figure 6 , Figures 13 to 17 As shown, the cleaning equipment also includes a locking assembly, which includes a movable part 40 and a locking part 50. The movable part 40 is fixedly connected to the support arm 210, and the locking part 50 is distributed opposite to the movable part 40 and slidably mounted on the machine body. When the support arm 210 and the movable part 40 rotate in a first direction, the locking part 50 tends to slide away from the movable part 40, so that the support arm 210 rotates synchronously with the mounting frame 110 and is in the working state. When the support arm 210 and the movable part 40 rotate in a second direction, the locking part 50 is driven to slide towards the movable part 40, and the locking part 50 locks with the movable part 40, so that the support arm 210 rotates relative to the mounting frame 110 and is in the switching state. The second direction is opposite to the first direction.

[0072] Specifically, during the rotation of the support mechanism 20 driven by the drive assembly 30, the part of the movable part 40 that abuts against the inner wall of the mounting bracket 110 is always driven to rotate by the support mechanism 20. When the locking part 50 disengages from the movable part 40, the part is relatively stationary with respect to the support mechanism 20. When the locking part 50 locks with the movable part 40, the part rotates under the drive of the locking part 50 while rotating with the support mechanism 20.

[0073] Furthermore, the locking part 50 is movably mounted on the body and always maintains relative rotation with the support mechanism 20, that is, the locking part 50 never rotates, and the locking part 50 slides toward or away from the moving part 40.

[0074] In this embodiment, when the drive assembly 30 rotates in the forward direction, the locking part 50 disengages from the movable part 40, the drive assembly 30 drives the support mechanism 20 to rotate, and the support mechanism 20 drives the mounting bracket 110 and the cleaning component to rotate, thereby achieving the cleaning effect on the surface to be cleaned; when the drive assembly 30 drives the support mechanism 20 to rotate in the reverse direction, the locking part 50 locks with the movable part 40, and the movable part 40 rotates on its own axis while following the rotation of the support mechanism 20, so that the movable part 40 drives the mounting bracket 110 to rotate, the mounting bracket 110 moves relative to the support protrusion 211 and achieves the switching of the support protrusion 211's abutting position, that is, the support protrusion 211 supports the first cleaning component 120 or supports the second cleaning component 130.

[0075] like Figure 1 As shown in Figure 3, the cleaning equipment also includes a drive assembly 30, which is mounted on the body and is connected to the support mechanism 20. The drive assembly 30 provides driving force for the rotation of the support mechanism 20.

[0076] Among them, the drive component 30 is a structural component such as a motor or cylinder that can provide rotational force.

[0077] Furthermore, the drive assembly 30 is driven to one end of the support mechanism 20, and the other end of the support mechanism 20 is rotatably connected to the machine body.

[0078] like Figures 4 to 6 As shown, the support mechanism 20 also includes a frame 200 and a transmission part 250. The movable part 40 and the support arm 210 are fixed on the frame 200. The support mechanism 20 is rotatably mounted on the body via the frame 200. The transmission part 250 is mounted on the frame 200 and moves synchronously with the frame 200. In the working state, the transmission part 250 and the locking part 50 remain relatively stationary. In the switching state, the transmission part 250 rotates with the frame 200 and drives the locking part 50 to move.

[0079] Specifically, in the switching state, the transmission part 250 rotates with the frame 200 and drives the locking part 50 to slide, so that the locking part 50 moves toward the movable part 40 and locks the movable part 40, thereby realizing that the movable part 40 drives the mounting frame 110 to slide relative to the support arm 210, and the abutting position of the support arm 210 changes.

[0080] Furthermore, the transmission part 250 is sleeved outside the locking part 50, and the inner wall of the transmission part 250 is connected to the outer wall of the locking part 50 by threads. A threaded drive is used so that when the transmission part 250 rotates with the frame 200, the transmission part 250 drives the locking part 50 to slide via the threads.

[0081] In this embodiment, the transmission part 250 has a limiting channel 251 for accommodating the locking part 50. The inner surface of the limiting channel 251 is provided with an internal thread, and the outer surface of the locking part 50 is provided with an external thread. The internal thread and the external thread are threadedly engaged.

[0082] The internal and external threads have a preset direction of rotation.

[0083] like Figures 4 to 6 As shown, the transmission part 250 is threadedly connected to the locking part 50, and the locking part 50 moves toward the movable part 40 and locks the movable part 40 only when the drive assembly 30 drives the support mechanism 20 to reverse. The movable part 40 restricts the rotation of the mounting bracket 110 so that only the support mechanism 20 rotates relative to the mounting bracket 110 by a preset angle under the action of the drive assembly 30. When the drive assembly 30 drives the support mechanism 20 to rotate forward, the locking part 50 moves toward the direction away from the movable part 40 and disengages from the movable part 40. The drive assembly 30 drives the cleaning assembly 10 to rotate synchronously through the support mechanism 20.

[0084] Specifically, the transmission part 250 and the locking part 50 are connected by threads so that when the drive assembly 30 drives the support mechanism 20 to rotate in the opposite direction, the support mechanism 20 rotates and can drive the locking part 50 to move toward the movable part 40 and lock the movable part 40 through the threads. When the drive assembly 30 drives the support mechanism 20 to rotate in the forward direction, the support mechanism 20 rotates and can drive the locking part 50 to move away from the movable part 40 through the threads. When the drive assembly 30 continues to drive the support mechanism 20 to rotate in the forward direction, due to the limitation of the thread direction and length on the transmission part 250 and the locking part 50, the support mechanism 20 will be rotatably connected to the locking part 50. That is, after the locking part 50 moves a certain distance, the transmission part 250 cannot continue to drive the locking part 50 to move.

[0085] like Figures 4 to 6As shown, the cleaning device includes a third end cap 80 and a third rotating shaft 70 mounted on the third end cap 80. The first end of the third rotating shaft 70 is connected to the machine body, and the second end of the third rotating shaft 70 extends into the limiting channel 251. The locking part 50 has a sliding hole, and the second end of the third rotating shaft 70 passes through the sliding hole to allow the locking part 50 to move towards or away from the movable part 40 along the direction of the third rotating shaft 70 when the support mechanism 20 and the locking part 50 are threadedly driven. The third rotating shaft 70 is fixedly connected to the machine body and always rotates relative to the support mechanism 20.

[0086] Furthermore, the extension direction of the third rotating shaft 70 is the same as the extension direction of the support mechanism 20 and the axial direction of the limiting channel 251.

[0087] Furthermore, to ensure that the locking part 50 can move along the third rotating shaft 70 without rotating under the threaded drive of the support mechanism 20, a guide protrusion is provided on one of the sliding hole and the third rotating shaft 70, and a guide groove is provided on the other. At least a portion of the guide protrusion slides inside the guide groove. Through the action of the guide protrusion and the guide groove, the locking part 50 can only move and cannot rotate.

[0088] In this embodiment, the cleaning device also includes an elastic element 60, one end of which is connected to the body and the other end of which abuts against the locking part 50. The elastic element 60 provides the locking part 50 with an elastic force to move in the direction of the movable part 40.

[0089] Under the action of the elastic member 60, the locking part 50 tends to move toward the moving part 40. When the drive assembly 30 drives the support mechanism 20 to rotate in the opposite direction, the support mechanism 20 can drive the locking part 50 to move due to the rotation direction of the internal and external threads.

[0090] like Figures 4 to 6 As shown, a locking member 510 is provided on the side of the locking part 50 facing the movable part 40, and the movable part 40 has a mating member 411 for cooperating with the locking member 510. In the switching state, the locking member 510 can engage with the mating member 411.

[0091] Specifically, when the locking part 50 and the moving part 40 are locked, the locking member 510 engages with the mating member 411 to achieve relative stillness between the locking part 50 and the moving part 40.

[0092] Furthermore, both the locking element 510 and the mating element 411 are ratchet structures.

[0093] Of course, it is not limited to the locking part 510 and the mating part 411 being ratchet structures; other structural methods that can lock each other to achieve relative fixation are also possible.

[0094] like Figures 13 to 18As shown, the frame 200 includes a rotating body, a first end cover 260, and a second end cover 270. The rotating body is rotatable under the drive of a driving force. A support arm 210 is fixed to the outer end of the rotating body along a direction perpendicular to the rotation axis of the rotating body. The first end cover 260 is fixed to the first end of the rotating body. The second end cover 270 is distributed outside the second end of the rotating body, and the two end covers form an installation area 280. The two ends of the support arm 210 along its length are respectively provided on the first end cover 260 and the second end cover 270. The movable part 40 is fixed to the rotating body and is located within the installation area 280. The transmission part 250 is provided on the second end cover 270. The locking part 50 is located within the installation area 280.

[0095] Specifically, the drive assembly 30 drives the rotating body to rotate, thereby driving the support arm 210 to rotate. The extension direction of the support arm 210 is the same as the extension direction of the rotating body. The two ends of the support arm 210 are respectively abutted against the first end cover 260 and the second end cover 270. The synchronous rotation between the support arm 210, the first end cover 260 and the second end cover 270 can be achieved through the linkage rotation of the support arm 210.

[0096] Furthermore, the locking part 50 slides within the mounting area 280 to move toward or away from the moving part 40.

[0097] Furthermore, the first end cover 260 is positioned close to the drive assembly 30, and a third end cover 80 is fixedly mounted on the body. The second end cover 270 is positioned between the first end cover 260 and the third end cover 80 and is close to the third end cover 80.

[0098] In this embodiment, the first end cap 260 and the second end cap 270 are provided with positioning grooves, and the support arm 210 is provided with a locking protrusion. At least a portion of the locking protrusion extends into the interior of the locking protrusion so as to realize the synchronous rotation of the support arm 210, the first end cap 260 and the second end cap 270.

[0099] like Figure 7 and Figure 8 As shown, the rotating body includes a first rotating shaft 220, at least one connecting section 221, and at least one second rotating shaft 230. The connecting section 221 extends radially along the first rotating shaft 220, with its inner end fixed to the first rotating shaft 220 and its outer end connected to the support arm 210. The second rotating shaft 230 is parallel to the first rotating shaft 220. The connecting section is mainly used to fix the support arm to the first rotating shaft, so the number of connecting sections corresponds to the number of support arms.

[0100] The first rotating shaft 220 and the second rotating shaft 230 are both extended along the extension direction of the cleaning component 10. The drive component 30 is driven to connect with the first rotating shaft 220. The second rotating shaft 230 is closer to the inner wall of the mounting bracket 110 than the first rotating shaft 220.

[0101] Specifically, the output shaft of the drive assembly 30 is driven to connect with the first rotating shaft 220 so that the first rotating shaft 220 can rotate. The first rotating shaft 220 drives the support arm 210 to rotate through the connecting section 221, and the support arm 210 drives the mountable bracket 110 to rotate.

[0102] Furthermore, both the first end cover 260 and the second end cover 270 are provided with positioning parts, which are positioning holes or positioning grooves. The two ends of the second rotating shaft 230 extend into the interior of the corresponding positioning parts of the first end cover 260 and the second end cover 270, respectively. The second rotating shaft 230 is rotatably connected to the positioning parts through bearings, so that the second rotating shaft 230 can be driven to rotate while the first end cover 260 and the second end cover 270 rotate synchronously.

[0103] In this embodiment, a bushing 240 is fitted onto the second rotating shaft 230 to allow the second rotating shaft 230 to abut against the inner wall surface of the mounting bracket 110 via the bushing 240. The bushing 240 may be made of rubber to increase the friction between the bushing 240 and the inner wall surface of the mounting bracket 110. When multiple second rotating shafts 230 are provided, they are spaced apart circumferentially along the first rotating shaft 220. The specific number of second rotating shafts 230 can be adjusted as needed. Naturally, the number of positioning portions on the first end cap 260 and the second end cap 270 corresponds to the number of second rotating shafts 230.

[0104] like Figure 7 and Figure 8 As shown, the movable part 40 also includes a drive wheel 410 and at least one driven wheel 420. The drive wheel 410 is disposed at the end of the first rotating shaft 220. The end face of the drive wheel 410 facing the locking part 50 has a mating part 411. The driven wheel 420 is sleeved and fixed on the second rotating shaft 230. The drive wheel 410 and the driven wheel 420 are drivenly connected. The outer periphery of the driven wheel 420 abuts against the inner wall surface of the mounting bracket 110.

[0105] Specifically, when the drive assembly 30 drives the frame 200 to rotate in the reverse direction, the locking member 510 on the locking part 50 locks the mating member 411, the drive wheel 410 is locked and stationary relative to the locking part 50. Since the drive wheel 410 is driven to rotate with the driven wheel 420, the driven wheel 420 rotates relative to the drive wheel 410. The driven wheel 420 drives the second rotating shaft 230 to rotate. The second rotating shaft 230 drives the mounting bracket 110 and the support protrusion 211 to move relative to each other through the bushing 240, so that the support mechanism 20 abuts against the first cleaning member 120 or the second cleaning member 130.

[0106] Furthermore, when there are multiple driven wheels 420, the multiple driven wheels 420 are arranged at circumferential intervals along the driving wheel 410.

[0107] Preferably, there are four second rotating shafts 230 and four driven wheels 420 arranged circumferentially along the first rotating shaft 220.

[0108] It should be noted that, in order to ensure that the driven wheel 420 can drive the second rotating shaft 230 to rotate, a protruding structure is provided on one of the second rotating shaft 230 and the driving wheel, and a groove-shaped structure is provided on the other of the second rotating shaft 230 and the driving wheel. At least part of the protruding structure extends into the interior of the groove-shaped structure so that the driven wheel 420 can drive the second rotating shaft 230 to rotate synchronously when it rotates.

[0109] Furthermore, the driving wheel 410 meshes with the driven wheel 420.

[0110] In this embodiment, the number of the first cleaning component 120 and the second cleaning component 130 can be adaptively set as needed, such as... Figures 7 to 10 As shown, the first cleaning component 120 and the second cleaning component 130 can each be provided in two pieces; as Figures 11 to 12 As shown, three of each of the first cleaning component 120 and the second cleaning component 130 are provided. Of course, other quantities are also possible.

[0111] It should be noted that when the first cleaning component 120 and the second cleaning component 130 can each be provided in two pieces, the number and arrangement of the supporting protrusions 211 will vary, such as... Figure 7 and Figure 8 As shown, the mounting bracket 110 can be in the shape of a running track; such as Figure 9 and Figure 10 As shown, the mounting bracket 110 can be an elliptical structure. For example... Figures 11 to 12 As shown, when the first cleaning component 120 and the second cleaning component 130 can each be provided in three pieces, the shape of the support protrusion 211 and the mounting bracket 110 are adapted accordingly.

[0112] Example 2

[0113] Unlike Example 1, as Figures 19 to 22 As shown, in this embodiment, the transmission part 250 is a first helical gear and the locking part 50 is a second helical gear. The transmission part 250 is slidably and rotatably mounted on the machine body. In the switching state, the first helical gear meshes with the second helical gear.

[0114] Specifically, the cleaning equipment also includes a locking assembly, which includes a movable part 40 and a locking part 50. The movable part 40 is fixedly connected to the support arm 210, and the locking part 50 is distributed opposite to the movable part 40. The locking part 50 is slidably and rotatably mounted on the machine body. When the support arm 210 and the movable part 40 rotate in the first direction, the locking part 50 remains separated from the movable part 40, so that the support arm 210 rotates synchronously with the mounting frame 110 and is in the working state. When the support arm 210 and the movable part 40 rotate in the second direction, the locking part 50 is linked to the movable part 40 and locked together, so that the support arm 210 rotates relative to the mounting frame 110 and is in the switching state. The second direction is opposite to the first direction.

[0115] Furthermore, in the switching state, the first helical gear meshes with the second helical gear; in the working state, the first helical gear and the second helical gear are spaced apart and disengaged.

[0116] The relationship between the transmission part 250 and the locking part 50 is realized by using a structure of a first helical gear and a second helical gear, which is simple in structure and easy to operate.

[0117] In this embodiment, the rotating body includes a first rotating shaft 220, at least one connecting section 221, and at least one second rotating shaft 230. The connecting section 221 extends radially along the first rotating shaft 220. The inner end of the connecting section 221 is fixed on the first rotating shaft 220, and the outer end of the connecting section 221 is connected to the support arm 210. The second rotating shaft 230 is parallel to the first rotating shaft 220. The transmission part 250 is fixed on the end of the first rotating shaft 220. The movable part 40 is sleeved and fixed on the second rotating shaft 230, and the locking part 50 is slidably sleeved on the second rotating shaft 230.

[0118] Specifically, the first rotating shaft 220 drives the support arm 210 to rotate via the connecting section 221. The support arm 210 abuts against the second end cover 270 to achieve synchronous rotation of the support arm 210 and the second end cover 270. In the working state, the first rotating shaft 220 rotates in the first direction, and the support arm 210 drives the mounting bracket to achieve rotation of the support arm 210 and the mounting bracket in the first direction. During the process of the support arm 210 driving the second end cover 270 to rotate, the second rotating shaft 230 rotates with the second end cover 270. The first rotating shaft 220 and the second rotating shaft 230 are relatively stationary, and the locking part 50 and the movable part 40 remain separated. In the switching state, the first rotating shaft 220... Rotating in the second direction, the first rotating shaft 220 drives the transmission part 250 to rotate. Since the transmission part 250 and the locking part 50 are structured as a first helical gear and a second helical gear meshing, when the transmission part 250 rotates in the second direction, the transmission part 250 and the locking part 50 are driven to rotate and slide toward the movable part 40. When the locking part 50 and the movable part 40 are locked, the transmission part 250 drives the second rotating shaft 230 to rotate through the locking part 50. At this time, the first rotating shaft 220 and the second rotating shaft move relative to each other, and the second rotating shaft 230 drives the mounting bracket to move, forcing the frame to deform, so as to realize the support arm 210 switching to abut against the first cleaning part or the second cleaning part.

[0119] Furthermore, a bushing 240 is provided on the second rotating shaft 230 to facilitate the deformation of the frame when switching states by increasing the damping between it and the mounting bracket.

[0120] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0121] 1. The mounting bracket 110 of the cleaning component 10 of this application is provided with a plurality of first cleaning components 120 and a plurality of second cleaning components 130, and the first cleaning component 120 or the second cleaning component 130 can be selectively selected for cleaning by the support mechanism 20, so as to improve the versatility of use.

[0122] 2. When selecting the first cleaning component 120 or the second cleaning component 130, only the rotation angle of the support mechanism 20 needs to be controlled, making the operation simple.

[0123] 3. No human intervention is required, saving labor costs, with a high degree of automation and a good user experience.

[0124] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
