[0042] Referring to Figure 1 As shown in the figure, the cleaning robot provided in the embodiment comprises a body 1 and a cleaning assembly 2, and the cleaning assembly 2 is movably connected with the body 1. Figure 2a As shown in the figure, the cleaning assembly 2 comprises a fixing seat 21, a locking device 22 and a cleaning unit 23. The fixing seat 21 is arranged on the body 1; the locking device 22 has an operating member 220; and the cleaning unit 23 is connected with the fixing seat 21 through the locking device 22. When the cleaning assembly 2 is movably extended from one side of the body 1, the operating member 220 is exposed, as shown in the figure. Figure 2a

[0043] The locking device 22 has a locking state and an unlocking state. When the locking device 22 is in the locking state, the cleaning unit 23 is stably connected with the fixing seat 21; and when the operating member 220 is actuated, the locking device 22 is switched from the locking state to the unlocking state, and the connection between the cleaning unit 23 and the fixing seat 21 is disconnected. When the cleaning robot is performing a cleaning task, the cleaning unit 23 can be in the extended state as shown in the figure to clean a cleaning object (such as a floor, a table top, etc.); of course, the cleaning unit 23 can also be in a retracted state (also referred to as an inner retracted state) to clean the cleaning object. When the cleaning unit is in the retracted state, the outer side end surface of the cleaning unit 23 is retracted to be flush with the outer contour edge of the body or inside the outer contour edge. Figure 2a

[0044] When the cleaning unit 23 is in the extended state as shown in the figure, the operating member 220 is exposed, which is convenient for the user to operate. The user operates the operating member 220 to actuate it, and the locking device 22 is in the unlocking state, so that the cleaning unit 23 is disconnected with the fixing seat 21, and thus the user can disassemble the cleaning unit 23 from the fixing seat 21. Figure 2a

[0045] As can be seen, the scheme provided in the embodiment solves the problem of easy falling off of the cleaning unit by connecting the cleaning unit with the fixing seat through the locking device; in addition, the operation of the locking device is simple, which is convenient for the user to disassemble and good for the user experience.

[0046] As shown in the figure, when the cleaning unit 23 is in the retracted state, i.e., the outer side end surface of the cleaning unit 23 is retracted to be flush with the outer contour edge of the body 1 or inside the outer contour edge, the operating member 220 is hidden inside the outer contour edge of the body 1. Figure 2b

[0047] ​​​​There are some devices, such as scrubber, the operating member is always exposed, which is convenient for user to operate. User can operate the operating member to detach the roller from the brush. But this always exposed operating member is easy to be mis-operated when the brush is working, such as the operating member collides with obstacles or hangs on the edge of wall / furniture, etc., which causes the roller to fall off from the brush. Or, when the scrubber is in non-working state, the scrubber is in vertical posture and stops in place. At this time, it is possible that a person or an animal accidentally bumps into the operating member, which causes the roller to loosen. When the user starts the scrubber or tilts the body of the scrubber, the loosened roller will fall off from the brush during the cleaning process, which is not good for user experience.

[0048] But the embodiment of the application needs to extend the cleaning assembly from the side of the body to expose the operating member when the cleaning unit needs to be detached. When the cleaning unit does not need to be detached, the cleaning assembly is in the retracted state, and the operating member is hidden inside the edge of the outer contour of the body, so the above-mentioned situation of the operating member being accidentally bumped into will not occur.

[0049] Referring to Figure 1 and 2a , along the direction of travel of the cleaning robot, the locking device 22 is located at the front side of the cleaning unit 23. Referring to the examples shown in Figure 2a and 2b , the cleaning assembly is in the retracted state, and the outer side end face of the cleaning unit 23 is retracted to be flush with the edge of the outer contour of the body 1. In order to adapt to the circular body, the rear side of the outer side end cover of the cleaning unit (the position circled by the dashed line in Figure 2a ) is a circular arc shape that matches the outer contour of the body. If the locking device is arranged at the rear side of the cleaning unit, due to the influence of this circular arc shaped end cover area, the locking device needs to be arranged at a very rear position. But the embodiment of the application provides a solution that the user operates the operating member to unlock the locking device, and then pulls out the cleaning unit from the fixed seat of the body by hand. If the locking device is arranged at the rear side of the cleaning unit, the user's hand needs to be stretched deeper, which either has the risk of pinching the hand or the roller needs to be swung out longer to prevent pinching the hand.

[0050] But the effect of arranging the locking device at the front side of the cleaning unit is better, referring to Figure 2a , the cleaning assembly only needs to extend a little bit to expose the operating member, and the user can operate the operating member of the locking device, which is more convenient for the user to operate.

[0051] As shown in the example of Figure 2a , the locking device 22 can be arranged above the cleaning unit 23. Compared with arranging the locking device at the middle or lower part of the cleaning unit, arranging the locking device above the cleaning unit is easier for the user to operate. Referring to Figure 2aIf the locking device is arranged at a lower position, the user's hand will touch the ground when operating the operating member. In order to avoid the hand touching the ground, one hand of the user is used to operate the operating member to disassemble the cleaning unit, and the other hand needs to lift the machine body to raise the operating member for convenient operation. It can be seen that arranging the locking device above the cleaning unit is appropriate in height, and the user does not need to lift the machine body, and one hand can operate the operating member to disassemble the cleaning unit from the fixing seat.

[0052] As shown in Figure 1 and Figure 2a , the cleaning assembly 2 further comprises a dust collecting box 3; the dust collecting box 3 is located at one side of the cleaning unit 23. For example, the dust collecting box 3 can be located at the front side or the rear side of the cleaning unit 23. Figure 1 An example in which the dust collecting box 3 is located at the front side of the cleaning unit 23 is shown. The locking device 22 is located above the dust collecting box 3. Correspondingly, the operating member 220 is located above the dust collecting box 3, and the user can operate with one hand when disassembling the cleaning unit 23. One finger of the hand operates the operating member 220, and the remaining fingers naturally hold the other side of the cleaning unit 23. After the operating member 220 is operated, the locking device 22 is in an unlocked state, the cleaning unit 23 is disconnected from the fixing seat 21, and the user's hand easily disassembles the cleaning unit 23. It can be seen that the embodiment fully utilizes the space, designs the locking device above the dust collecting box 3, and also considers the convenience of the user disassembling the cleaning unit with one hand. The user can easily complete the disassembly with one hand.

[0053] Referring to the examples shown in Figure 1 and Figure 6 , the cleaning unit 23 comprises a roller 232. In combination with the direction mark shown in Figure 1 , the locking device 22 is located above the roller 232; and / or the locking device 22 is located at the front side of the roller 232. Figure 1 The position corresponding to the elliptical dashed line in is the position of the locking device 22.

[0054] Figure 4 As shown in Figure 8 , the cleaning unit 23 comprises a roller 232 and an end cover 231. As shown in Figure 7 , one end of the roller 232 is connected with the motor 25; and the end cover 231 is arranged at the other end of the roller 232. The end cover 231 is connected with the fixing seat 21 through the locking device 22. As shown in , the locking device 22 can be located at the inner side of the end cover 231. The outer side of the end cover 231 is the side facing outward, and the inner side of the end cover 231 is the side opposite to the outer side. The operating member 220 of the locking device 22 can be directed to the front side of the machine body.

[0055] Further, the corresponding end cover 231 of the fixing seat 21 can be provided with a first structure 4, and the inner side of the end cover 231 of the cleaning unit 23 is provided with a second structure 5. The first structure 4 and the second structure 5 can be matched, and can play a positioning role. Of course, the first structure 4 and the second structure 5 can also be magnetic components used in cooperation. For example, as shown in Figure 6 and Figure 8 , one of the first structure 4 and the second structure 5 is a groove, and the other is a protrusion, and the groove and the protrusion are matched. Further, the protrusion is a magnet, and the groove is provided with a magnetic material; or the groove is provided with a magnet, and the protrusion is provided with a magnetic material, and the like, which are not limited in the embodiment.

[0056] The body 1 of the cleaning robot can be provided with a key, a voice interaction module or a touch screen, and the user can trigger the cleaning assembly 2 to extend through the key, voice or touch screen. The extension amount can be that the operation member is exposed. If the cleaning robot is executing a cleaning task, the cleaning assembly is in an extended state. The extension amount of the cleaning assembly when the cleaning unit is disassembled can be less than or equal to the extension amount when the cleaning assembly is working. As shown in Figure 2a , the cleaning assembly 2 extends out of the edge of the body 1. At this time, the user can see the cleaning assembly 2 when looking at the upper part of the body 1, and can also see the end cover 231 of the cleaning unit 23. As shown in the example of Figure 2a , the end cover 231 of the cleaning unit 23 is similar to a whistle. The front side of the end cover 231 is provided with the operation member 220 of the locking device 22. Referring to Figure 2a , the user uses a finger of one hand to press the operation member 220, and the remaining fingers can pinch the rear side of the end cover 231 or hold the roller. Then, as shown in Figure 3 , the operation member 220 is pressed to the rear side of the body 1, and the locking device 22 is in an unlocked state; at this time, the user can easily pull out the cleaning unit along the pulling-out direction (that is, the width direction of the body 1, which is also the axial direction of the roller), that is, Figure 4 Y direction in Figure 4 , the user can also see the opening of the roller cavity of the fixing seat 21, and inserts one end of the cleaning unit 23 (such as the roller) into the opening, and the end cover 231 of the cleaning unit cooperates with the first structure 4 on the fixing seat 21, and the locking device 22 is switched to a locked state, so that the cleaning unit 23 is connected with the fixing seat 21. If the cleaning robot needs to perform a cleaning task after installation, the cleaning robot remains in the current extended state of the cleaning assembly 2 to perform the cleaning task. If the cleaning robot needs to return to the base station after installation, the cleaning robot automatically retracts the cleaning assembly 2 after detecting that the cleaning assembly 2 is installed. Or, the user triggers the mainboard of the cleaning robot through the interaction device to control the driving device to retract the cleaning assembly 2.

[0057] In some specific embodiments, the operating element 220 may be a push button. See also Figure 4 As shown, the direction of the push button's movement is different from the direction in which the cleaning unit 23 is detached from the mounting base 21; wherein, when the push button is operated in the direction of movement, the locking device 22 switches from the locked state to the unlocked state.

[0058] For example, such as Figure 1 The directional markings shown indicate that the push button should be pressed in the backward direction of unit 1. Figure 4 The X direction in the middle. The disassembly direction of cleaning unit 23 is the extension direction of cleaning component 2, that is... Figure 4 The Y-direction in the middle.

[0059] like Figure 6 and Figure 7 The example shown illustrates a locking device 22 including an operating member 220, a locking groove 222, and a resilient member 223. The operating member 220 is provided with a locking hook 221. (The text repeats itself here.) Figure 2a and Figure 3 As shown, the locking groove 222 is adapted to the locking hook 221; one end of the elastic member 223 is connected to the operating member 220, and the other end is connected to the cleaning unit 23. The operating member 220 is disposed on the cleaning unit 23, and the locking groove 222 is disposed on the fixed base 21.

[0060] Among them, the elastic element 223 can be a spring, an elastic body made of elastic material, etc.

[0061] like Figure 3 As shown, the operating element 220 is as follows Figure 3 After applying the operating force in the direction indicated by the middle arrow, the locking hook 221 moves from... Figure 2a The hook lock position shown (the hook lock position where the hook 221 mates with the groove edge of the lock groove 222) is moved to... Figure 3 The unlocked position is shown (the locking hook 221 is away from the groove edge of the locking groove 222). In this way, the locking device 22 switches from the locked state to the unlocked state. In the unlocked state, the elastic element 223 is in a deformed state.

[0062] The installation process is from Figure 3 to Figure 2a The reverse process. When the cleaning unit 23 is installed on the fixed base 21, that is, one end of the cleaning unit 23 is connected to the motor 25, the second structure 5 on the end cover 231 of the cleaning unit 23 is engaged with the first structure 4 on the fixed base 21. Figure 2a and Figure 3As shown, the groove of the lock slot 222 has a slope, and the same, the lock hook 221 is also provided with a slope. During the installation of the cleaning unit 23, after the lock hook 221 contacts the groove, under the joint action of the slope on the groove and the slope on the lock hook 221, the lock hook 221 slides into the lock slot 222; when the user releases his hand (i.e. no force is applied to the operating member 220), under the elastic restoring force of the elastic member, the lock hook 221 is driven out of the lock slot 222 under the action of the slope on the lock slot 222. Figure 3 As shown, the lock hook is moved to the unlocked position Figure 2a As shown, the hook is moved to the locked position, and at this time, the locking device 22 is in the locked state.

[0063] In the embodiment, the operating member is a push knob, and in fact, the operating member can also be other structural components, such as a knob, a rotating knob, etc., and the embodiment does not make specific limitations on this. For example, the operating member 220 is a knob, and the user can drive the lock hook into or out of the lock slot by rotating the knob. For example, the operating member 220 is a rotating knob, and the user can drive the lock hook into the lock slot by rotating the knob in a first rotating direction (e.g. counterclockwise), and the user can drive the lock hook out of the lock slot by rotating the knob in a second rotating direction (e.g. clockwise).

[0064] As shown in Figure 6 and Figure 7 The operating member 220 is a push knob, and along the pushing direction of the push knob, the push knob has two opposite ends, which are a first end and a second end. The end face of the first end of the push knob is an operating face 2201; the lock hook 221 is arranged on the side face of the push knob and close to the second end of the push knob. The cleaning unit is provided with a sliding channel, and the push knob is arranged in the sliding channel.

[0071] In fact, the cleaning assembly 2 in the embodiment can be in an extended state normally. For example, when the cleaning robot is started, the main board controls the cleaning assembly 2 to move relative to the body 1 to extend from one side of the body 1, and the cleaning assembly 2 is in the extended state. When the cleaning robot performs a cleaning task and traverses a region to be cleaned, the cleaning assembly 2 remains in the extended state (as shown in FIG. 1B). If the cleaning robot encounters an obstacle or passes through a narrow space, the main board controls the cleaning assembly 2 to retract to hide in the body 1, so as to facilitate obstacle avoidance or passing through a narrow space. In the extended state of the cleaning assembly 2, the outer side edge of the cleaning assembly 2 can be flush with the edge of the widest part of the body 1, or the outer side edge of the cleaning assembly 2 can exceed the edge of the widest part of the body 1. Figure 2a Specifically, as shown in FIG. 1C, the fixed seat 21 in the embodiment can have a first opening downward and a second opening laterally. The lower part of the cleaning unit 23 passes through the first opening to contact the surface to be cleaned. The cleaning unit 23 can be detached through the second opening, and the second opening is located on the same side as the position on the body 1 for the cleaning assembly to extend. For example, when a user wants to clean or replace the cleaning unit 23, the user can see the cleaning unit 23 at the position on the body 1 for the cleaning assembly 2 to extend, and then detach the cleaning unit 23 at the second opening. When installing, the cleaning unit 23 can be inserted from the second opening, and after the end of the cleaning unit 23 is connected to the motor 25, the other end of the cleaning unit 23 is connected to the second opening. That is, the direction of disassembly and assembly of the cleaning unit 23 is the length direction of the cleaning unit 23. If the cleaning unit 23 is a roller, the direction of disassembly and assembly is the axis direction of the roller.

[0072] Figure 8 Referring to FIG. 1D, the liquid supply mechanism can have a plurality of liquid supply openings 6, and the liquid supply mechanism can supply cleaning liquid to the cleaning unit 23 through the plurality of liquid supply openings 6. The dirt removal mechanism can include a scraper 7 as shown in FIG. 1E, which can act on the cleaning unit 23. The dirt scraped off by the scraper 7 enters the dirt collection box 3.

[0074] ​​​The cleaning assembly in the embodiment can be used as a separate product, and the cleaning assembly can be replaced. For example, the cleaning robot can be provided with cleaning assemblies of different materials and different styles. Alternatively, when the roller in the cleaning assembly of the cleaning robot is seriously worn, a new cleaning assembly can be replaced. That is, another embodiment of the utility model provides a cleaning assembly which can be used on the above-mentioned cleaning robot. As shown in Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the cleaning assembly comprises a fixing seat 21, a locking device 22 and a cleaning unit 23. The locking device 22 has an operating part 220, the cleaning unit 23 is connected with the fixing seat 21 through the locking device 22, and the operating part 220 is located at the end of the cleaning assembly 2.

[0075] The locking device 22 has a locking state and an unlocking state. When the locking device 22 is in the locking state, the cleaning unit 23 is stably connected with the fixing seat 21, the operating part 220 is actuated, the locking device 22 is switched to the unlocking state, and the connection between the cleaning unit 23 and the fixing seat 21 is disconnected.

[0076] The cleaning assembly 2 further comprises a dirt collecting box 3 which is located at one side of the cleaning unit 23, such as the front side or the rear side. The locking device 22 can be located above the dirt collecting box 3.

[0077] It should be noted that the specific structure of the locking device 22, the cleaning unit 23 and the like in the embodiment can refer to the content in the foregoing, and will not be described herein.

[0078] In addition, the application further provides a cleaning robot. The cleaning robot comprises a body 1 and a cleaning assembly 2. The cleaning assembly 2 is movably connected with the body 1. The cleaning assembly 2 comprises a fixing seat 21, a locking device 22 and a cleaning unit 23. The fixing seat 21 is arranged on the body 1, and the locking device 22 has an operating part 220. The cleaning unit 23 is connected with the fixing seat 21 through the locking device 22. The cleaning assembly 2 has at least a retracted state and an extended state.

[0079] As Figure 2b , when the cleaning assembly 2 is in the retracted state, the operating part 220 is located in the projection area of the body 1. That is, the operating part 220 is located inside the body and is in a hidden state.

[0080] As Figure 2a , when the cleaning assembly 2 is in the extended state, the cleaning assembly 2 extends from at least one side of the body 1, so that at least part of the operating part 220 is located outside the projection area of the body 1. That is, the operating part 220 is exposed, which is convenient for the user to operate.

[0081] The scheme provided by the embodiment is that when the cleaning unit needs to be disassembled and cleaned, the cleaning assembly extends from one side of the machine body, and the operating member is exposed; when disassembly is not needed, the cleaning assembly is in a retracted state, and the operating member is hidden inside the edge of the outer contour of the machine body, so that the operating member is not accidentally touched.

[0082] The scheme provided by the embodiment of the utility model will be described below in combination with a specific use scenario.

[0083] The user starts the cleaning robot to clean the floor of the home. After the cleaning robot drives out of the base station, the cleaning robot controls the cleaning assembly to extend to the extended state as shown in the figure, and then performs a cleaning task according to a planned path or a user instruction. During the execution of the task by the cleaning robot, the cleaning unit is connected to the fixed seat through the locking device, the locking device is in the locked state, the cleaning unit is fixed on the fixed seat, and the cleaning unit will not fall off. Figure 2a

[0084] During the process, the user wants to disassemble the cleaning unit. The user instructs the cleaning robot to stop working through a client (such as an application APP on a mobile phone) or a control on the cleaning robot. The cleaning robot stops moving, and the cleaning assembly is still in the extended state at this time. At this time, the user can directly operate the operating member, the locking device is unlocked, and the connection between the cleaning unit and the fixed seat is disconnected. The user can easily take out the cleaning unit. After taking out, the user can replace a new cleaning unit and install the cleaning unit on the fixed seat. The user releases the locking device, and the locking device switches to the locked state, and the cleaning unit is connected to the fixed seat.

[0085] In another scenario, the cleaning assembly of the cleaning robot is in the retracted state, and the user can instruct the cleaning robot to extend the cleaning assembly through a control on the machine body of the cleaning robot, voice control, or a touch screen. After the cleaning assembly is in the extended state, the user can operate the operating member, the locking device is unlocked, the connection between the cleaning unit and the fixed seat is disconnected, and the cleaning unit can be easily disassembled.
