[0032] The present application provides a cleaning device and a cleaning assembly, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0033] See also Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the cleaning device of the present application.

[0034] In one embodiment, the cleaning device 10 may be a cleaning robot with cleaning functions such as washing, mopping, and wiping the floor. The cleaning device 10 can automatically move on the surface 30 to be cleaned to clean the area it passes through. The cleaning device 10 may also be a cleaning device such as a cleaning machine or a floor scrubber. The user holds the cleaning device 10 and pushes the cleaning device 10 to move on the surface 30 to be cleaned to clean the area it passes through. The embodiment of the present application uses a cleaning robot as an example to illustrate the cleaning device 10, which is only for the purpose of discussion and does not limit the type of the cleaning device 10. Among them, the surface 30 to be cleaned may be the ground, or the surface to be cleaned of an object, etc.

[0035] Specifically, the cleaning device 10 includes a device body 11. The device body 11 is the main part of the cleaning device 10, and is used to carry and protect the remaining parts of the cleaning device 10. Optionally, the device body 11 may be provided with a mechanism for driving the cleaning device 10 to walk, such as a driving wheel, a crawler, etc.

[0036] Please also read Figure 2 The cleaning device 10 further includes a cleaning assembly 24, which is used to clean the surface to be cleaned 30. The cleaning assembly 24 includes a cleaning member 242, and the cleaning assembly 24 cleans the surface to be cleaned 30 through the cleaning member 242. Optionally, the cleaning member 242 can be a cleaning element such as a roller brush, and the cleaning member 242 can rotate around its own central axis to clean the surface to be cleaned 30. Of course, in other embodiments of the present application, the cleaning member 242 can also be a cleaning element such as a roller or a rag, which is not limited here.

[0037] Please also read Figures 3 to 5The cleaning device 10 further includes a driving assembly 21, which is disposed on the device body 11. The driving assembly 21 includes a lifting mechanism 22 and a pressurizing mechanism 23. The cleaning assembly 24 is in transmission cooperation with the lifting mechanism 22 and the pressurizing mechanism 23. The lifting mechanism 22 is used to drive the cleaning assembly 24 to approach or move away from the surface to be cleaned 30, that is, the lifting mechanism 22 is used to drive the cleaning assembly 24 to move up and down. When the lifting mechanism 22 is used to drive the cleaning assembly 24 to rise, the lifting mechanism 22 drives the cleaning assembly 24 away from the surface to be cleaned 30, so that there is a large distance between the cleaning assembly 24 and the surface to be cleaned 30, which is conducive to improving the obstacle avoidance ability of the cleaning device 10. When the lifting mechanism 22 is used to drive the cleaning assembly 24 to descend, the lifting mechanism 22 drives the cleaning assembly 24 to approach the surface to be cleaned 30, so that the cleaning assembly 24 abuts against the surface to be cleaned 30 to clean the surface to be cleaned 30.

[0038] It should be noted that the lifting mechanism 22 of the embodiment of the present application is used to drive the cleaning component 24 to rise, and the cleaning component 24 can be close to the surface to be cleaned 30 at least under the action of its own gravity, that is, the cleaning component 24 can descend at least under the action of its own gravity, and the lifting mechanism 22 supports the descending operation of the cleaning component 24. Figure 3 The cleaning component 24 is shown in a normal state of cleaning the surface to be cleaned 30 . At this time, the cleaning component 24 at least abuts against the surface to be cleaned 30 under the action of its own gravity to clean the surface 30 . Figure 4 The figure shows the state where the lifting mechanism 22 drives the cleaning assembly 24 to rise.

[0039] The pressurizing mechanism 23 is used to apply pressure to the cleaning component 24 toward the surface 30 to be cleaned when the cleaning component 24 cleans the surface 30 to be cleaned. The pressure makes the cleaning component 24 close to the surface 30 to be cleaned, which is beneficial to improving the cleaning effect of the cleaning component 24. Figure 5 The state in which the pressurizing mechanism 23 applies pressure to the cleaning assembly 24 toward the surface to be cleaned 30 is shown. Compared with the passive pressurizing method that increases the weight of the cleaning assembly 24, this embodiment uses the pressurizing mechanism 23 to actively pressurize the cleaning assembly 24, thereby avoiding the problem of excessive weight and high cost of the cleaning device 10 caused by the increase in the weight of the cleaning assembly 24, thereby helping to reduce the weight of the cleaning device 10 of this embodiment and reduce the cost.

[0040] In one embodiment, the pressure mechanism 23 includes an elastic member 231 . The elastic member 231 is connected to the lifting mechanism 22 , and the elastic member 231 applies pressure to the cleaning assembly 24 through the lifting mechanism 22 .

[0041] Specifically, the driving assembly 21 also includes a mounting seat 211, and the mounting seat 211 is arranged on the device body 11. The cleaning assembly 24 is movably arranged on the mounting seat 211. The lifting mechanism 22 includes a lifting lever 221. The lifting lever 221 is rotatably arranged on the mounting seat 211, and the lifting lever 221 is transmission-connected with the cleaning assembly 24. In the process of the lifting mechanism 22 driving the cleaning assembly 24 to rise, the lifting lever 221 is rotated relative to the mounting seat 211 so that the cleaning assembly 24 is away from the surface to be cleaned 30. When the cleaning assembly 24 approaches the surface to be cleaned 30 at least under the action of its own gravity, the lifting lever 221 can rotate in the opposite direction with the cleaning assembly 24 to support the descending operation of the cleaning assembly 24. The pressurizing mechanism 23 also includes a pressurizing rod 232. The pressurizing rod 232 is rotatably arranged on the mounting seat 211, and the pressurizing rod 232 is connected to the lifting lever 221 through the elastic member 231. When the cleaning assembly 24 cleans the surface 30 to be cleaned, the pressure rod 232 rotates relative to the mounting seat 211 so that the elastic member 231 applies pressure to the cleaning assembly 24 .

[0042] For further information, please also refer to Figure 6 , the driving assembly 21 also includes a rotating shaft 216. The lifting lever 221 and the pressure rod 232 are both rotatably arranged on the mounting seat 211 through the rotating shaft 216. The rotating shaft 216 is arranged on the mounting seat 211, and the lifting lever 221 and the pressure rod 232 are both rotatably connected to the rotating shaft 216. The elastic member 231 can be an elastic element such as a torsion spring. The main body of the elastic member 231 is sleeved on the outer periphery of the rotating shaft 216, and one free arm of the elastic member 231 abuts the lifting lever 221, and the other free arm abuts the pressure rod 232. By rotating the pressure rod 232 relative to the mounting seat 211, the pressure rod 232 forces the lifting lever 221 to press down the cleaning assembly 24 through the elastic member 231, thereby applying pressure to the cleaning assembly 24 toward the surface to be cleaned 30. The elastic force provided by the torsion spring is relatively stable and controllable, which can greatly reduce the shaking and noise of the cleaning assembly 24 after pressurization.

[0043] It should be noted that the pressure rod 232 is detachably connected to the mounting seat 211, and the elastic member 231 is detachably connected to the lifting lever 221. In other words, the pressure rod 232 and the elastic member 231 of this embodiment are detachably designed, and even if the pressure rod 232 and the elastic member 231 are removed, the lifting design of the cleaning assembly 24 can be normally realized.

[0044] Of course, in other embodiments of the present application, it is not limited to driving the elastic member 231 to apply pressure to the cleaning assembly 24 through the pressure rod 232. For example, an elastic element such as a spring can be arranged between the end of the lifting lever 221 away from the cleaning assembly 24 and the mounting seat 211, and the elastic restoring force provided by the spring enables the lifting lever 221 to apply pressure to the cleaning assembly 24 toward the surface to be cleaned 30, which is not limited here.

[0045] In one embodiment, the driving assembly 21 further includes a driving member 212, which is disposed on the mounting seat 211. The driving member 212 is used to cooperate with the lifting lever 221 and the pressure rod 232 in transmission. The driving member 212 is a power source of the driving assembly 21, and the driving member 212 can be a power element such as a motor. The driving assembly 21 further includes a driving seat 215, which is fixed to the mounting seat 211, and the driving member 212 is installed on the driving seat 215.

[0046] The driving assembly 21 further includes a first transmission rod 213. The first transmission rod 213 is in transmission connection with the driving member 212, and the first transmission rod 213 is used for transmission cooperation with the lifting lever 221. The driving assembly 21 further includes a second transmission rod 214. The second transmission rod 214 is in transmission connection with the driving member 212, and the second transmission rod 214 is used for transmission cooperation with the pressure rod 232. The driving assembly 21 can switch between the first state and the second state. Figure 4 As shown, when the driving assembly 21 is in the first state, the lifting lever 221 rotates to make the cleaning assembly 24 away from the surface to be cleaned 30, and the cleaning assembly 24 is in the raised position. Figure 5 As shown, when the driving assembly 21 is in the second state, the lifting lever 221 rotates until the cleaning assembly 24 abuts against the cleaning surface 30 , at which time the cleaning assembly 24 is in a lowered position, and the pressure rod 232 forces the elastic member 231 to apply pressure to the cleaning assembly 24 through the lifting lever 221 .

[0047] During the process of switching the driving component 21 to the first state, the driving member 212 drives the first transmission rod 213 and the second transmission rod 214 to rotate along the first rotation direction, and the first transmission rod 213 drives the lifting lever 221 to rotate, so that the lifting lever 221 drives the cleaning component 24 away from the surface to be cleaned 30, and the second transmission rod 214 and the pressure rod 232 cancel the transmission cooperation, that is, at this time, the pressure rod 232 does not apply pressure to the cleaning component 24. During the process of the drive assembly 21 switching to the second state, the drive member 212 drives the first transmission rod 213 and the second transmission rod 214 to rotate along the second rotation direction, which is opposite to the first rotation direction. The second transmission rod 214 drives the pressure rod 232 to rotate, so that the elastic member 231 applies pressure to the cleaning assembly 24 through the lifting lever 221, and the first transmission rod 213 and the lifting lever 221 cancel the transmission cooperation, that is, at this time, the cleaning assembly 24 at least descends under the action of its own gravity and abuts against the surface to be cleaned 30. The aforementioned pressure makes the cleaning assembly 24 close to the surface to be cleaned 30 to improve the cleaning effect of the cleaning assembly 24. At this time, the cleaning assembly 24 as a whole has a certain amount of floating, that is, the cleaning assembly 24 can passively approach or move away from the surface to be cleaned 30 with the ups and downs of the surface to be cleaned 30, and the cleaning assembly 24 can adaptively match the ups and downs of the surface to be cleaned 30 and remain close to the surface to be cleaned 30, which is further conducive to improving the cleaning effect of the cleaning assembly 24.

[0048] Furthermore, the drive assembly 21 also has a third state. Figure 3 As shown, when the driving assembly 21 is in the third state, the first transmission rod 213 and the lifting lever 221 cancel the transmission cooperation, and the second transmission rod 214 and the pressure rod 232 cancel the transmission cooperation, and the cleaning assembly 24 at least abuts against the surface to be cleaned 30 under the action of its own gravity to clean the surface to be cleaned 30. In other words, when the driving assembly 21 is in the third state, the cleaning assembly 24 is in a normal state of cleaning the surface to be cleaned 30, and the driving assembly 21 and the cleaning assembly 24 are disconnected from the transmission connection, and the cleaning assembly 24 is in a floating state as a whole, that is, the cleaning assembly 24 can passively move in a direction away from the surface to be cleaned 30 under the action of obstacles on the surface to be cleaned 30, which is conducive to improving the obstacle avoidance ability of the cleaning device 10 and reducing the risk of damage to the cleaning device 10. If the driving assembly 21 and the cleaning assembly 24 always have a transmission relationship, resulting in the cleaning assembly 24 being unable to float, on the one hand, it will affect the obstacle avoidance ability of the cleaning device 10, and on the other hand, the cleaning device 10 will forcibly pass through the obstacle and easily cause damage to the cleaning device 10.

[0049] It should be noted that the driving component 21 is configured to switch from the third state to the first state or the second state. In other words, the third state is the basic state of the driving component 21, and the state switching process of the driving component 21 is switching from the third state to the first state, or switching from the third state to the second state. In addition, the present embodiment enables the driving member 212 to realize the lifting design and pressurization design of the cleaning component 24 by setting the first transmission rod 213 and the second transmission rod 214. Compared with the situation where the lifting design and pressurization design of the cleaning component 24 are respectively realized by different power elements, the present embodiment can reduce the number of driving members 212, which is conducive to reducing the cost of the cleaning device 10.

[0050] Furthermore, the cleaning device 10 is provided with sensors for the above three states of the driving component 21 to monitor the state switching process of the driving component 21. For the design in which the driving member 212 is a motor, the state switching is realized by controlling the driving member 212 through software, and by controlling the number of motor turns, the dual control mechanism enables the driving member 212 to accurately switch to the corresponding state, which is conducive to ensuring the stability of the mechanism. In addition, the cleaning device 10 is provided with hard limits for the rising state and the pressurized state of the cleaning component 24, so that the cleaning component 24 can be reliably limited even when the software control fails.

[0051] In one embodiment, the driving assembly 21 has a preset direction (eg Figure 6 The lifting lever 221 and the pressure rod 232 are sequentially distributed along the preset direction. In the preset direction, the first transmission rod 213 is arranged relative to the lifting lever 221, so that the first transmission rod 213 can cooperate with the lifting lever 221 in transmission, and the first transmission rod 213 is also spaced apart from the pressure rod 232, which can avoid the interference between the first transmission rod 213 and the pressure rod 232, that is, avoid the mutual interference between the lifting and lowering process and the pressure process of the cleaning component 24. Similarly, in the preset direction, the second transmission rod 214 is arranged relative to the pressure rod 232, so that the second transmission rod 214 can cooperate with the pressure rod 232 in transmission, and the second transmission rod 214 is also spaced apart from the lifting lever 221, which can avoid the interference between the second transmission rod 214 and the lifting lever 221, that is, avoid the mutual interference between the lifting and lowering process and the pressure process of the cleaning component 24.

[0052] In one embodiment, the extension direction of the first transmission rod 213 is different from the extension direction of the second transmission rod 214, that is, the center line of the first transmission rod 213 is set at an angle to the center line of the second transmission rod 214. In other words, this embodiment can avoid the mutual interference between the lifting process and the pressurization process of the cleaning component 24 by reasonably setting the relative position relationship between the first transmission rod 213 and the second transmission rod 214, specifically, avoid the transmission cooperation between the second transmission rod 214 and the pressurization rod 232 during the lifting process of the cleaning component 24.

[0053] In one embodiment, the mounting seat 211 has a mounting cavity 2111, the cleaning assembly 24 is mounted in the mounting cavity 2111, and the mounting seat 211 is further provided with a through hole 2112 communicating with the mounting cavity 2111. Figure 7 The driving member 212 is installed on the portion of the mounting seat 211 outside the mounting cavity 2111, specifically, the driving seat 215 is located outside the mounting cavity 2111, and the driving member 212 is installed on the driving seat 215. The lifting lever 221 is penetrated through the through hole 2112, so that the lifting lever 221 can be connected to the cleaning component 24 in a transmission manner, and the lifting lever 221 can also cooperate with the driving member 212 in a transmission manner.

[0054] In one embodiment, the cleaning assembly 24 is rotatably disposed on the mounting seat 211. When the cleaning assembly 24 approaches or moves away from the surface to be cleaned 30, the cleaning assembly 24 rotates relative to the mounting seat 211. Specifically, the cleaning assembly 24 also includes a cleaning seat 241, and a cleaning member 242 is disposed on the cleaning seat 241. The cleaning seat 241 is rotatably connected to the mounting seat 211, so that the cleaning assembly 24 can rotate relative to the mounting seat 211.

[0055] Since the rotation center of the cleaning assembly 24 is different from the rotation center of the lifting lever 221, there is a relative movement between the cleaning assembly 24 and the lifting lever 221 during the rotation of the cleaning assembly 24. In view of this, the cleaning seat 241 is provided with a slide groove 243, and the lifting mechanism 22 also includes a moving member 222, which is arranged on the lifting lever 221, and the moving member 222 is also movably arranged in the slide groove 243. The lifting lever 221 and the cleaning seat 241 are connected by transmission between the moving member 222 and the slide groove 243, and the lifting lever 221 drives the cleaning seat 241 to rotate relative to the mounting seat 211 through the transmission cooperation between the moving member 222 and the slide groove 243, and the moving member 222 moves synchronously along the slide groove 243 to adapt to the relative movement between the cleaning assembly 24 and the lifting lever 221. Furthermore, under the action of the elastic member 231 , the lifting lever 221 cooperates with the slide slot 243 through the moving member 222 to apply pressure to the cleaning assembly 24 toward the surface 30 to be cleaned.

[0056] Optionally, the moving member 222 may be a pulley, etc., that is, there is rolling friction between the moving member 222 and the groove wall of the slide groove 243, which can reduce the friction resistance between the moving member 222 and the cleaning seat 241. In addition, the lifting lever 221 is provided with moving members 222 on both sides of the preset direction. Of course, in other embodiments of the present application, the moving member 222 itself may not roll, and the moving member 222 may slide with the slide groove 243, which is not limited here.

[0057] For example, the driving assembly 21 is located in front of the cleaning device 10. The front end of the cleaning assembly 24 is rotatably connected to the mounting seat 211. The lifting mechanism 22 and the pressurizing mechanism 23 are located above the cleaning assembly 24. The cleaning seat 241 is connected to the dust box of the cleaning device 10 through a hose, and the dirt is recovered into the dust box through the hose. The hose can adapt to the lifting design of the cleaning assembly 24, while keeping the recovery channel between the cleaning assembly 24 and the dust box unobstructed.

[0058] In one embodiment, the cleaning assembly 20 includes a driving assembly 21. The driving assembly 21 includes a lifting mechanism 22 and a pressurizing mechanism 23. The cleaning assembly 20 also includes a cleaning assembly 24. The cleaning assembly 24 is in transmission cooperation with the lifting mechanism 22 and the pressurizing mechanism 23, and the cleaning assembly 24 is used to clean the surface to be cleaned 30. The lifting mechanism 22 is used to drive the cleaning assembly 24 to approach or move away from the surface to be cleaned 30, and the pressurizing mechanism 23 is used to apply pressure to the cleaning assembly 24 toward the surface to be cleaned 30 during the process of the cleaning assembly 24 cleaning the surface to be cleaned 30.

[0059] It should be noted that the driving component 21 and the cleaning component 24 of this embodiment have been described in detail in the above embodiments and will not be repeated here.

[0060] The technical solution provided in the embodiments of the present application is described below in conjunction with specific application scenarios.

[0061] Application scenario 1:

[0062] The cleaning device 10 is a cleaning robot. The cleaning device 10 includes a device body 11. The cleaning device 10 also includes a driving assembly 21, which is arranged on the device body 11. The driving assembly 21 includes a lifting mechanism 22 and a pressurizing mechanism 23. The cleaning device 10 also includes a cleaning assembly 24, which is in transmission cooperation with the lifting mechanism 22 and the pressurizing mechanism 23. The cleaning assembly 24 is used to clean the surface 30 to be cleaned, the lifting mechanism 22 is used to drive the cleaning assembly 24 to approach or move away from the surface 30 to be cleaned, and the pressurizing mechanism 23 is used to apply pressure to the cleaning assembly 24 toward the surface 30 to be cleaned during the cleaning of the surface 30 by the cleaning assembly 24. The cleaning member 242 of the cleaning assembly 24 is a roller brush.

[0063] When the cleaning device 10 normally cleans the surface to be cleaned 30, the driving assembly 21 is in the third state, the first transmission rod 213 and the lifting lever 221 cancel the transmission cooperation, and the second transmission rod 214 and the pressure rod 232 cancel the transmission cooperation, and the cleaning assembly 24 at least contacts the surface to be cleaned 30 under the action of its own gravity to clean the surface to be cleaned 30. The driving assembly 21 is disconnected from the cleaning assembly 24, and the cleaning assembly 24 is in a floating state as a whole, which is conducive to improving the obstacle avoidance ability of the cleaning device 10 and reducing the risk of damage to the cleaning device 10.

[0064] When the cleaning device 10 detects that the surface 30 to be cleaned is seriously contaminated, the cleaning device 10 controls the driving component 21 to switch from the third state to the first state, and the lifting lever 221 of the lifting mechanism 22 rotates to make the cleaning component 24 move away from the surface 30 to be cleaned, so as to prevent the cleaning component 24 from being contaminated by the surface 30 to be cleaned, thereby reducing the frequency of maintenance of the cleaning component 24 by the user. At this time, the cleaning device 10 uses the rag thereon to clean the surface 30 to be cleaned.

[0065] When the cleaning device 10 detects that there is a lot of dust or particles on the surface to be cleaned 30, the cleaning device 10 controls the driving component 21 to switch from the third state to the second state, and the lifting lever 221 rotates until the cleaning component 24 abuts against the surface to be cleaned 30. The pressing rod 232 of the pressing mechanism 23 forces the elastic member 231 to apply pressure to the cleaning component 24 through the lifting lever 221. The pressure makes the cleaning component 24 close to the surface to be cleaned 30, which is conducive to improving the cleaning effect of the cleaning component 24. In addition, the cleaning component 24 as a whole has a certain amount of floating, that is, the cleaning component 24 can passively approach or move away from the surface to be cleaned 30 with the ups and downs of the surface to be cleaned 30, and the cleaning component 24 can adaptively match the ups and downs of the surface to be cleaned 30 and remain close to the surface to be cleaned 30.

The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
