Description

Technical Field

[0001] This invention relates to the field of cleaning devices, and more particularly to a cleaning device. Background Technology

[0002] Existing cleaning devices, such as floor scrubbers, require manual operation of the unlocking device to unlock them when they need to be laid down, followed by manual operation of the machine body. Similarly, when the machine body needs to be locked, it needs to be manually uprighted and then manually operated to lock it. During this process, the user's hands cannot be freed, and the user cannot perform other operations at the same time, resulting in a poor user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a cleaning device that allows a user to unlock and release the main unit with one hand, thereby freeing up the user's other hand to perform other operations simultaneously, thus improving the user experience.

When the limiting portion is in a limiting engagement with the mating portion, the main body remains upright. When the limiting portion rotates with the fixing portion and disengages from the mating portion, the main body can rotate with the rotating shaft.

[0005] According to an embodiment of the cleaning device of the present invention, a mating part is provided on the outer peripheral wall of the rotating shaft at the lower end of the main body; a first limiting pedal is also provided, including a fixing part, a limiting part, and a stepping part. The limiting part is connected to the fixing part, one end of the fixing part is rotatably connected to the floor brush assembly, and the stepping part is connected to the fixing part. When the limiting part and the mating part are engaged, the main body remains upright. This allows the user to unlock the main body simply by stepping on the stepping part and lowering the main body, and to lock the main body simply by stepping on the stepping part and keeping the main body upright. This allows the user to operate the unlocking and releasing of the main body with one hand, enabling the user's other hand to perform other operations simultaneously, thereby improving the user experience.

[0006] In some embodiments of the present invention, the cleaning device further includes a first elastic element, one end of which is connected to the first limiting button and the other end of which is connected to the floor brush assembly, for driving the limiting part to rotate toward the rotating shaft.

[0008] In some embodiments of the present invention, the locking mechanism includes: a locking component mounted on the floor brush assembly, wherein the wastewater tank can be locked onto the floor brush assembly by the locking component; and a switch component mounted on the floor brush assembly and connected to the locking component, wherein the switch component is used to control the locking component to unlock the wastewater tank.

[0009] In some embodiments of the present invention, the locking assembly includes: a spring-loaded support, the spring-loaded support being movably disposed within the floor brush assembly, the end of the spring-loaded support opposite to the wastewater tank being adapted to abut against the switch assembly, and the switch assembly being able to provide space for the spring-loaded support to move in the direction opposite to the wastewater tank when the wastewater tank is unlocked; a locking spring, the locking spring being fixed on the spring-loaded support for locking the wastewater tank; and a spring-loaded elastic element, the spring-loaded elastic element being disposed within the floor brush assembly for driving the spring-loaded support to move the locking spring in the direction opposite to the wastewater tank.

[0010] In some embodiments of the present invention, the locking assembly further includes a second elastic element, one end of which is connected to the spring support and the other end of which is connected to the locking spring, for driving the locking spring to move toward the sewage tank.

[0011] In some embodiments of the present invention, the switch assembly includes: a pop-up bracket, which is rotatably disposed within the floor brush assembly and has a first position and a second position. The pop-up bracket has a stop protrusion. In the locked state, the pop-up bracket is located in the first position, and the stop protrusion abuts against the locking mechanism. In the unlocked state, the pop-up bracket is located in the second position, and the stop protrusion is offset from the locking mechanism. A third elastic member, one end of which is connected to the floor brush assembly and the other end of which is connected to the pop-up bracket, for driving the pop-up bracket to move from the first position to the second position. The mechanism rotates from the first position to the second position; a latch, movably disposed within the floor brush assembly, has a third position and a fourth position. In the locked state, the latch is located in the third position and engages with the pop-up bracket; in the unlocked state, the latch is located in the fourth position and disengages from the pop-up bracket; a second limiting pedal, movably disposed on the floor brush assembly, drives the latch to move from the third position to the fourth position, thereby driving the locking mechanism to switch from the locked state to the unlocked state.

[0012] In some embodiments of the present invention, the first limiting pedal further includes a driving part, the driving part being connected to the fixing part, the driving part being adapted to abut against the second limiting pedal, and the second limiting pedal driving the driving part to rotate the fixing part so that the limiting part and the mating part disengage.

[0013] In some embodiments of the present invention, the second limit pedal has a second guide slope that abuts against the driving part.

[0014] In some embodiments of the present invention, the second limiting pedal has a first guide slope that abuts against the latch. When the locking mechanism is driven to switch from the locked state to the unlocked state, the first guide slope is inclined in the direction away from the latch along the moving direction of the second limiting pedal.

[0015] In some embodiments of the present invention, the switch assembly further includes: a fourth elastic member, one end of which is connected to the floor brush assembly, and the other end of which is connected to the latch, for driving the latch to move from the fourth position to the third position.

[0016] In some embodiments of the present invention, the end of the pop-up bracket away from the rotation axis of the pop-up bracket has a mating inclined surface, and the main body has a pushing part. When the main body switches to the upright state, the pushing part abuts against the mating inclined surface, thereby driving the pop-up bracket to move from the second position to the first position.

[0017] In some embodiments of the present invention, the lower surface of the sewage tank has a mounting portion, the upper surface of the floor brush assembly has a mounting groove, the mounting portion is located in the mounting groove, and the outer peripheral wall of the mounting portion has a limiting protrusion.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The cleaning apparatus 10 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0044] like Figure 1 As shown, the cleaning device 10 according to an embodiment of the present invention includes a floor brush assembly 1, a main body 2, and a first limit button.

[0045] Specifically, refer to Figures 1-4 The lower end of the main body 2 is provided with a rotating shaft 21, which is rotatably connected to the floor brush assembly 1. The outer peripheral wall of the rotating shaft 21 is provided with a mating part 211. The first limit button 3 includes a fixing part 31, a limiting part 32 and a stepping part 33. One end of the fixing part 31 is rotatably connected to the floor brush assembly 1. The limiting part 32 is connected to the fixing part 31. The stepping part 33 is connected to the fixing part 31. When the limiting part 32 is engaged with the mating part 211, the main body 2 remains upright. When the limiting part 32 rotates with the fixing part 31 and disengages from the mating part 211, the main body 2 can rotate with the rotating shaft 21.

[0046] It is understood that the main body 2 and the rotating shaft 21 are relatively fixed, and the main body 2 and the rotating shaft 21 will rotate synchronously. When the limiting part 32 engages with the cooperating part 211, it can restrict the rotation of the cooperating part 211 towards the lying position of the main body 2, thereby restricting the rotation of the rotating shaft 21 towards the lying position of the main body 2, thus restricting the main body 2 from lying down, and achieving locking of the main body 2 in the upright state, thereby keeping the main body 2 in an upright state. The foot pedal 33 extends rearward for easy user operation. By stepping on the foot pedal 33, the user drives the first limiting pedal 3 to rotate towards the lying position of the main body 2, thereby causing the limiting part 32 to rotate with the fixing part 31 and disengage from the cooperating part 211. The main body 2 can then rotate with the rotating shaft 21, thereby unlocking the main body 2 and allowing it to lie down.

[0047] For example in Figures 1-3 In the example shown, when the limiting part 32 engages with the mating part 211, and the main body 2 remains upright while the first limiting button 3 also remains upright, the main body 2 is vertically locked. When the user steps on the foot pedal 33, because the end of the fixing part 31 furthest from the foot pedal 33 (lower end) is rotatably connected to the base plate (not shown) of the floor brush assembly 1, the foot pedal 33 rotates in the direction of the main body 2 lying down. This causes the first limiting button 3 to rotate around the connection point between the fixing part 31 and the base plate of the floor brush assembly 1 in the direction of the main body 2 lying down, thereby separating the limiting part 32 from the mating part 211, thus unlocking the main body 2 and allowing it to lie down (e.g., in...). Figure 1 and Figure 2 (Lying down backwards), while the user can operate the unlocking and releasing of the main body 2 with one hand, so that the user's other hand can perform other operations at the same time, thereby improving the user experience.

[0048] The upper and lower ends of the main body 2 refer to the upper and lower ends of the main body 2 when the main body 2 is in an upright state. In addition, the front end refers to the forward direction of the cleaning device 10, and the rear end refers to the backward direction of the cleaning device 10. For example, the rotating shaft 21 is located at the front end of the foot pedal 33, and the foot pedal 33 is located at the rear end of the rotating shaft 21.

[0049] The following is based on Figures 1-4 The example shown illustrates the unlocking and locking process of the main body 2: In the initial position, the first limit button 3 is in an upright state, and the limit part 32 and the mating part 211 cooperate with each other (e.g., Figure 4 As shown), the main body 2 is locked in the upright position.

[0050] When it is necessary to lie down on the main body 2, the user steps on the foot pedal 33, and the foot pedal 33 moves in the direction of lying down on the main body 2 (e.g., in...). Figure 2As shown in the counterclockwise direction, the first limit button 3 rotates around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 towards the lying direction of the main body 2, thereby causing the limit part 32 to rotate away from the rotating shaft 21, so that the limit part 32 rotates with the fixing part 31 and disengages from the mating part 211. At this time, the main body 2 is unlocked, and the user lays the main body 2 down, completing the unlocking and lying down of the main body 2.

[0051] When the main body 2 needs to be kept upright (from the lying position to the upright position), the first limit button 3 is in the upright position. When the user steps on the foot pedal 33, the foot pedal 33 rotates in the lying direction of the main body 2, thereby causing the first limit button 3 to rotate around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 in the lying direction of the main body 2. This causes the limiting part 32 to rotate in a direction away from the rotating shaft 21, thus changing the main body 2 from the lying position to the upright position. The rotating shaft 21 rotates accordingly, and the mating part 211 rotates in the vertical direction of the main body 2. Then, the foot pedal 33 is released, and the limiting part 32 is operated to rotate in the direction of the rotating shaft 21, so that the limiting part 32 and the mating part 211 cooperate, thereby locking the first limit button 3.

[0052] Therefore, the steps for unlocking and locking the main unit are reduced, and the locking and unlocking process is simple, improving the user experience.

[0053] According to an embodiment of the cleaning device 10 of the present invention, a mating part 211 is provided on the outer peripheral wall of the rotating shaft 21 at the lower end of the main body 2; a first limiting pedal 3 is also provided, including a fixing part 31, a limiting part 32, and a stepping part 33. The limiting part 32 is connected to the fixing part 31, one end of the fixing part 31 is rotatably connected to the floor brush assembly 1, and the stepping part 33 is connected to the fixing part 31. When the limiting part 32 and the mating part 211 are engaged, the main body 2 remains upright. This allows the user to unlock the main body 2 by stepping on the stepping part 33 and lowering the main body 2, and to lock the main body 2 by stepping on the stepping part 33 and keeping the main body 2 upright. This allows the user to operate the unlocking and releasing of the main body 2 with one hand, so that the user's other hand can perform other operations at the same time, such as holding objects, thereby improving the user experience.

[0054] In some embodiments of the present invention, the cleaning device 10 further includes a first elastic element (not shown), one end of which is connected to the first limiting button 3 and the other end is connected to the floor brush assembly 1, for driving the limiting part 32 to rotate toward the rotating shaft 21.

[0055] It is understood that one end of the first elastic element is connected to at least one of the fixing part 31, the limiting part 32, and the stepping part 33, and the other end is connected to the floor brush assembly 1, for driving the limiting part 32 to rotate toward the rotating shaft 21. When the first limiting pedal 3 is in an upright state, the first elastic element is in its initial state (the first elastic element is under minimal force). When the user steps on the stepping part 33, the first limiting pedal 3 rotates toward the direction where the main body 2 is lying down, and the first elastic element extends or contracts. When the user releases the stepping part 33, the first elastic element drives the limiting part 32 to rotate toward the rotating shaft 21, so that the first limiting pedal 3 can automatically return to its initial position without manual operation, simplifying the operation process. At the same time, when the first limiting pedal 3 is in its initial position, the first elastic element can keep the first limiting pedal 3 in an upright state without external force, making the first limiting pedal 3 stable and reliable. In the embodiments of the present invention, the initial position of the first limiting pedal 3 is an upright state.

[0056] exist Figure 2 and Figure 3 In the example shown, the side of the fixing part 31 facing away from the limiting part 32 has a first spring bracket 4 for connecting one end of the first elastic member, thereby connecting the first elastic member to the fixing part 31. However, the present invention is not limited to this. One end of the first elastic member may also be connected only to the limiting part 32 or the stepping part 33, or connected to the fixing part 31 and the limiting part 32 but not to the stepping part 33; or connected to the limiting part 32 and the stepping part 33 but not to the fixing part 31; or connected to the fixing part 31 and the stepping part 33 but not to the limiting part 32; or connected to the fixing part 31, the limiting part 32 and the stepping part 33.

[0057] The following is based on Figures 1-4 The example shown illustrates the operation of the first elastic element during the unlocking and locking process of the main body 2: In the initial position, the first limit button 3 is in an upright state, and the limit part 32 and the mating part 211 cooperate with each other (e.g., Figure 4 (As shown), the main body 2 is locked in an upright position. The first elastic member is connected to the side of the fixing part 31 opposite to the limiting part 32.

[0058] When it is necessary to lie down on the main body 2, the user steps on the foot pedal 33, and the foot pedal 33 moves in the direction of lying down on the main body 2 (e.g., in...). Figure 2The first limit button 3 rotates counterclockwise (as shown in the diagram), causing the first limit button 3 to rotate around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 towards the lying position of the main body 2. This causes the limit part 32 to rotate away from the rotating shaft 21, thus separating the limit part 32 from the mating part 211. During this process, the first elastic element contracts, and the main body 2 is unlocked. The user lays the main body 2 down, and the rotating shaft 21 rotates accordingly. The mating part 211 rotates towards the lying position of the main body 2, releasing the foot pedal 33. At this time, the first elastic element extends, driving the limit part 32 to rotate towards the rotating shaft 21, so that the first limit button 3 remains upright, completing the unlocking and lying down of the main body 2.

[0059] When the main body 2 needs to be kept upright (from the lying position to the upright position), the first limit button 3 is in the upright position. When the user steps on the foot pedal 33, the foot pedal 33 rotates in the lying direction of the main body 2, thereby causing the first limit button 3 to rotate around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 in the lying direction of the main body 2. This causes the limiting part 32 to rotate in a direction away from the rotating shaft 21. During this process, the first elastic element contracts, changing the main body 2 from the lying position to the upright position. The rotating shaft 21 rotates accordingly, and the mating part 211 rotates in the vertical direction of the main body 2. Then, the foot pedal 33 is released, and the first elastic element extends, driving the limiting part 32 to rotate in the direction of the rotating shaft 21. This causes the limiting part 32 to engage with the mating part 211, thereby locking the first limit button 3.

[0060] In some embodiments of the present invention, such as Figures 1-4 As shown, the mating part 211 is a mating protrusion formed on the rotating shaft 21. When the main body 2 is kept upright, the limiting part 32 is located on the side of the mating protrusion facing the direction of the main body 2 lying down and abuts against the mating protrusion.

[0061] Understandably, the mating protrusion extends in a direction away from the axis of rotation 21, and the limiting part 32 is located on the side of the mating protrusion facing the lying direction of the main body 2 and abuts against the mating protrusion, which can restrict the main body 2 from lying down and improve the reliability of locking the main body 2. For example, in Figures 2-4 In the example shown, since the main body 2 is lying down in a counterclockwise direction, the limiting part 32 is located on the lower side of the mating protrusion. This allows the mating protrusion to restrict the main body 2 from lying down when the main body 2 is in an upright state, thus improving the reliability of locking the main body 2.

[0062] Furthermore, such as Figures 1-4As shown, when the first limit button 3 is in the initial position, and the main body 2 is in a horizontal position, the mating part 211 is located on the side of the limit part 32 facing the horizontal direction of the main body 2. For the main body 2 to move from the horizontal position to an upright position and lock into the upright position, the mating part 211 needs to be located on the side of the limit part 32 facing away from the bottom plate of the floor brush assembly 1. When the first limit button 3 is in the initial position, in the direction from the end of the first limit button 31 facing away from the bottom plate of the floor brush assembly 1 to the end near the bottom plate of the floor brush assembly 1, the end face of the limit part 32 facing the rotation shaft 21 is inclined towards the fixation part 31, thereby forming a third guide slope 321 on the side of the limit part 32 facing the rotation shaft 21. Therefore, when the main body 2 moves from a lying position to an upright position, the mating part 211 can rotate via the third guide ramp 321 to the side of the limiting part 32 opposite to the bottom plate of the floor brush assembly 1, thereby enabling the main body 2 to move from a lying position to an upright position and lock in the upright position. This eliminates the need to operate the first limiting button 3, simplifying the operation and the locking process of the main body 2. Of course, if the third guide ramp 321 is ineffective, the locking process of the main body 2 can still be achieved by operating the first limiting button 3.

[0063] Thus, a second method for the main body 2 to change from a lying position to an upright position is realized: when it is necessary to keep the main body 2 in an upright position (from the lying position to the upright position), the first limit button 3 is in an upright position. When the user drives the main body 2 from the lying position to the upright position, the rotating shaft 21 rotates accordingly, and the mating part 211 rotates in the vertical direction of the main body 2. The mating part 211 is directly located on the side of the limit part 32 away from the bottom plate of the floor brush assembly 1 through the third guide slope 321 of the limit part 32, thereby locking the main body 2 in the upright position.

[0064] In some embodiments of the present invention, such as Figure 1 As shown, the cleaning device 10 also includes a wastewater tank 5 and a locking mechanism 6. The wastewater tank 5 is located above the floor brush assembly 1, and the locking mechanism 6 is located on the floor brush assembly 1. The locking mechanism 6 has a locked state for limiting the wastewater tank 5 and an unlocked state for releasing the wastewater tank 5.

[0065] Understandably, the wastewater tank 5 is used to hold the waste collected by the cleaning device 10 during cleaning. The locking mechanism 6 has a locking state for limiting the wastewater tank 5, so that the wastewater tank 5 can be fixed on the floor brush assembly 1 to prevent the wastewater tank 5 from falling off, so that the cleaning device 10 can work normally. The locking mechanism 6 also has an unlocking state for releasing the wastewater tank 5, so that the wastewater tank 5 and the floor brush assembly 1 can be separated, thereby enabling the cleaning and maintenance of the wastewater tank 5. This improves the ease of disassembly and assembly of the wastewater tank 5.

[0066] Furthermore, such as Figure 11As shown, the floor brush assembly 1 also includes an air duct component 12 and a housing 13. The air duct component 12 is located below the locking mechanism 6. At least a portion of the air duct component 12 and the locking mechanism 6 are located inside the housing 13. The upper end of the air duct component 12 has a first air duct opening 121 for connecting with the mounting part 51. The front end of the air duct component 12 has a second air duct opening 122. The first air duct opening 121 and the second air duct opening 122 are connected. The air duct component 12 passes through the front end and the upper end of the housing 13. The second air duct opening 122 is used for garbage suction, and the first air duct opening 121 is used for connecting with the mounting part 51 and transporting the garbage into the sewage tank 5 to achieve the cleaning effect.

[0067] In some embodiments of the present invention, such as Figure 1 As shown, the locking mechanism 6 includes a locking component 62 and a switch component 61. The locking component 62 is installed on the floor brush assembly 1, and the wastewater tank 5 can be locked onto the floor brush assembly 1 by the locking component 62. The switch component 61 is installed on the floor brush assembly 1 and connected to the locking component 62. The switch component 61 is used to control the locking component 62 to unlock the wastewater tank 5. Thus, the locking component 62 can cause the locking mechanism 6 to enter the locking state from the unlocked state, and the switch component 61 can control the locking mechanism 6 to enter the unlocked state from the locked state.

[0068] In some embodiments of the present invention, such as Figures 5-8 As shown, the locking assembly 62 includes a spring-loaded support 621, a locking spring 623, and a spring-loaded elastic element 622. The spring-loaded support 621 is movably disposed within the floor brush assembly 1. The end of the spring-loaded support 621 facing away from the wastewater tank 5 is adapted to abut against the switch assembly 61. When the wastewater tank 5 is unlocked, the switch assembly 61 can provide space for the spring-loaded support 621 to move in the direction away from the wastewater tank 5. The locking spring 623 is fixed on the spring-loaded support 621 and is used to lock the wastewater tank 5. The spring-loaded elastic element 622 is disposed within the floor brush assembly 1 and is used to drive the spring-loaded support 621 to move the locking spring 623 in the direction away from the wastewater tank 5. One end of the spring-loaded elastic element 622 is connected to the floor brush assembly 1.

[0069] Understandably, in the locked state, the end of the spring tongue support 621 that is away from the sewage tank 5 and far from the spring elastic member 622 is spaced apart from the switch assembly 61, forming a mating groove 66. The end of the spring tongue support 621 that is away from the sewage tank 5 and close to the spring elastic member 622 abuts against the switch assembly 61, thereby allowing the switch assembly 61 to restrict the movement of the spring tongue support 621 in the direction away from the sewage tank 5, thus locking the sewage tank 5 with the locking spring tongue 623. When the locking mechanism 6 enters the unlocked state from the locked state, when the switch assembly 61 enters the mating groove 66, the switch assembly 61 can provide space for the spring tongue support 621 to move in the direction away from the sewage tank 5, i.e., the space of the mating groove 66, so that the spring tongue support 621 can move in the direction away from the sewage tank 5, thereby allowing the locking spring tongue 623 to be spaced apart from the sewage tank 5, thus unlocking the sewage tank 5.

[0070] In some embodiments of the present invention, such as Figures 5-8 As shown, the locking assembly 62 also includes a second elastic element 624. One end of the second elastic element 624 is connected to the spring support 621, and the other end is connected to the locking spring 623, for driving the locking spring 623 to move toward the sewage tank 5. Thus, the second elastic element 624 can improve the reliability of the locking spring 623 and the sewage tank 5, thereby making the sewage tank 5 reliably locked.

[0071] Meanwhile, the deformation range of the second elastic element 624 must ensure that, in the unlocked state, the locking tongue 623 and the sewage tank 5 are spaced apart in the radial direction of the sewage tank 5, thereby ensuring that the locking mechanism 6 can release the sewage tank 5.

[0072] In some embodiments of the present invention, such as Figure 1 As shown, the switch assembly 61 includes a pop-up bracket 615, a second limit button 616, a third elastic element 63, and a latch 64. The pop-up bracket 615 is rotatably disposed within the floor brush assembly 1 and has a first position and a second position. The pop-up bracket 615 has a stop protrusion 611. In the locked state, the pop-up bracket 615 is located in the first position, and the stop protrusion 611 abuts against the locking mechanism 6. In the unlocked state, the pop-up bracket 615 is located in the second position, and the stop protrusion 611 is offset from the locking mechanism 6.

[0073] It is understandable that, such as Figures 5-8As shown, the stop protrusion 611 is located at the upper end of the pop-up bracket 615. The stop protrusion 611 extends towards the axis of the sewage tank 5. In the locked state, the stop protrusion 611 and the lower side of the end of the spring tongue support 621 opposite to the sewage tank 5 abut against each other, thereby causing the stop protrusion 611 to abut against the locking mechanism 6. The pop-up bracket 615 moves upward, thus moving from the first position to the second position, thereby allowing the stop protrusion 611 to move upward. In the unlocked state, the stop protrusion 611 can enter the mating groove 66. The lower side of the end of the spring tongue support 621 away from the sewage tank 5 is offset from the stop protrusion 611, which in turn offsets the stop protrusion 611 from the locking mechanism 6. This allows the spring elastic element 622 to drive the spring tongue support 621 to move in a direction away from the axis of the sewage tank 5, and the locking spring tongue 623 to move in a direction away from the axis of the sewage tank 5. This allows the locking spring tongue 623 to be spaced apart from the sewage tank 5 in the radial direction of the sewage tank 5, thereby allowing the locking mechanism 6 to release the sewage tank 5.

[0074] In addition, such as Figures 5-8 As shown, the pop-up bracket 615 has a clearance hole 65 for avoiding the locking assembly 62. The stop protrusion 611 is located inside the clearance hole 65. When the pop-up bracket 615 is in the first position, the bottom end of the pop-up bracket 615 is spaced apart from the bottom wall of the clearance hole 65, so that when the pop-up bracket 615 moves from the first position to the second position, the interference between the bottom wall of the clearance hole 65 and the bottom end of the pop-up bracket 615 is avoided, thereby ensuring that the pop-up bracket 615 can smoothly move from the first position to the second position.

[0075] When the locking mechanism 6 moves from the locked state to the unlocked state, the spring-loaded bracket 615 moves upward, from the first position to the second position. The stop protrusion 611 also moves upward, so that the stop protrusion 611 enters the mating groove 66. At this time, the lower side of the end of the spring tongue support 621 that is away from the axis of the sewage tank 5 is offset from the stop protrusion 611. The rebound elastic element 622 can drive the spring tongue support 621 to move in the direction away from the axis of the sewage tank 5, so that the locking spring tongue 623 can move in the direction away from the axis of the sewage tank 5, so that the locking spring tongue 623 and the sewage tank 5 are spaced apart in the radial direction of the sewage tank 5, so that the locking mechanism 6 can release the sewage tank 5.

[0076] exist Figure 1 In the example shown, there are two locking mechanisms 6 spaced apart, but the present invention is not limited to this. There can be more locking mechanisms 6, such as 3, 4, 5 or 6, etc.

[0077] Furthermore, such as Figure 1 , Figures 5-8 and Figure 13As shown, one end of the third elastic member 63 is connected to the floor brush assembly 1, and the other end is connected to the pop-up bracket 615, which is used to drive the pop-up bracket 615 to rotate from the first position to the second position; the latch 64 is located inside the floor brush assembly 1, and in the locked state, the latch 64 and the pop-up bracket 615 are engaged.

[0078] Understandably, the pop-up bracket 615 has a support column 613 extending along the direction from the first position to the second position. One end of the support column 613 facing the bottom plate of the floor brush assembly 1 has a recessed groove along the direction from the first position to the second position of the pop-up bracket 615. One end of the third elastic member 63 is connected to the floor brush assembly 1, and the other end is located inside the support column 613 and connected to the top wall of the groove. The housing 13 has a through hole 131 for the support column 613 to pass through, thereby restricting the movement of the pop-up bracket 615 in the radial direction along the through hole 131, while the support column 613 can move in the axial direction of the through hole 131. Thus, the third elastic member 63 can drive the pop-up bracket 615 to rotate from the first position to the second position.

[0079] Furthermore, such as Figure 1 , Figure 11 and Figure 13 As shown, the latch 64 extends along the axis of the rotation shaft 21. The air duct component 12 has a movable channel 123, which extends along the axis of the rotation shaft 21. One end of the movable channel 123 is open, allowing the latch 64 to be located within the movable channel 123. In the locked state, the latch 64 and the pop-up bracket 615 engage, thereby restricting the pop-up bracket 615 from rotating from the first position to the second position, ensuring the locking of the sewage tank 5.

[0080] Furthermore, such as Figure 1 , Figure 11 and Figure 13 As shown, the latch 64 is movably disposed within the floor brush assembly 1. The latch 64 has a third position and a fourth position. In the locked state, the latch 64 is located in the third position and is engaged with the pop-up bracket 615. In the unlocked state, the latch 64 is located in the fourth position and is disengaged from the pop-up bracket 615.

[0081] Understandably, the latch 64 is movably located within the movable channel 123. In the locked state, the latch 64 is in the third position, and the latch 64 is engaged with the pop-up bracket 615. At this time, the third elastic element 63 retracts, and the pop-up bracket 615 is in the first position. The latch 64 can move from the third position to the fourth position by moving away from the opening of the movable channel 123, thereby releasing the latch 64 from the pop-up bracket 615. At this time, the third elastic element 63 is released, thereby driving the pop-up bracket 615 to rotate from the first position to the second position, thereby unlocking the sewage tank 5 by the locking mechanism 6.

[0082] Furthermore, such as Figure 1 , Figure 11 and Figure 13 As shown, the second limit pedal 616 is movably mounted on the floor brush assembly 1, used to drive the latch 64 from the third position to the fourth position to drive the locking mechanism 6, thereby driving the locking mechanism 6 to switch from the locked state to the unlocked state. Thus, in the locked state, the latch 64 is located in the third position, with part of the latch 64 outside the active channel 123, facilitating the stop between the second limit pedal 616 and the latch 64. When the user steps on the second limit pedal 616, it drives the latch 64 from the third position to the fourth position, thereby driving the locking mechanism 6 to switch from the locked state to the unlocked state.

[0083] In addition, such as Figure 10 and Figure 12 As shown, the second limiting button 616 has a plurality of claws 6163 spaced apart along the circumferential direction of the second limiting button 616 on its peripheral wall. The housing 13 has a positioning groove 132 for mounting the second limiting button 616. The inner peripheral wall of the positioning groove 132 has a plurality of guide grooves 133 corresponding one-to-one with the claws 6163. The claws 6163 are movably disposed in the guide grooves 133. The guide grooves 133 extend along the axial direction of the floor brush assembly 1, so that the second limiting button 616 can move in the guide grooves 133. At the same time, the claws 6163 are located in the guide grooves 133. One end of the bottom wall of the positioning groove 132 of the claws 6163 has a protrusion extending away from the center of the second limiting button 616. Through the cooperation of the protrusion with the inner peripheral wall of the guide groove 133, the second limiting button 616 can be prevented from detaching from the floor brush assembly 1.

[0084] For example in Figure 12 and Figure 10 In the example shown, there are four claws 6163 and four guide grooves 133. However, the present invention is not limited to this. There may be more or fewer claws 6163 and guide grooves 133, such as 3, 5, 6 or 7.

[0085] In some embodiments of the present invention, such as Figure 1 and Figure 9 As shown, the pop-up bracket 615 has a mating inclined surface 614 at one end away from the rotation axis of the pop-up bracket 615, and the main body 2 has a pushing part 22. When the main body 2 switches to the upright state, the pushing part 22 abuts against the mating inclined surface 614, which is used to drive the pop-up bracket 615 to move from the second position to the first position.

[0086] It is understood that the pop-up bracket 615 has a pivot 612 at the end opposite to the main body 2, and a mating inclined surface 614 at the end opposite to the pivot 612. The pivot 612 extends along the direction of the rotation axis 21, so that the pop-up bracket 615 can rotate relative to the floor brush assembly 1. In the front-to-back direction, the mating inclined surface 614 is inclined downward, and the pushing part 22 extends forward, so that the pushing part 22 and the mating inclined surface 614 can stop each other, so that the pop-up bracket 615 can be driven to move from the second position to the first position, thereby realizing the locking mechanism 6 to reset to the locked state, so that the locking mechanism 6 can lock the sewage tank 5.

[0087] In some embodiments of the present invention, such as Figure 13 As shown, the second limit pedal 616 has a first guide slope 6161 that abuts against the latch 64. When the driving locking mechanism 6 switches from the locked state to the unlocked state, the first guide slope 6161 tilts in the direction away from the latch 64 along the moving direction of the second limit pedal 616. Figure 10 and Figure 12 As shown, there is one second limit button 616. The first guide slope 6161 is set opposite to the open opening of the active channel 123, so that the second limit button 616 can drive the latch 64 to move from the third position to the fourth position to drive the locking mechanism 6 to switch from the locked state to the unlocked state.

[0088] It is understandable that, such as Figure 13 As shown, the first guide slope 6161 is located on the end of the second limit button 616 facing the latch 64. Along the direction from the fourth position to the third position of the latch 64, the end face of the latch 64 facing the second limit button 616 is inclined along the moving direction of the second limit button 616 (the moving direction when driving the locking mechanism 6 to switch from the locked state to the unlocked state). Since the latch 64 is located in the active channel 123, the latch 64 cannot move along the moving direction of the second limit button 616, but can only move along the extension direction of the active channel 123. When the second limit button 616 moves in the direction of driving the locking mechanism 6 to switch from the locked state to the unlocked state, the end face of the latch 64 facing the second limit button 616 cooperates with the first guide slope 6161 to stop, thereby facilitating the second limit button 616 to drive the latch 64 to move from the third position to the fourth position to drive the locking mechanism 6 to switch from the locked state to the unlocked state, thus improving the unlocking efficiency.

[0089] When it is necessary to release the sewage tank 5, the user drives the second limit button 616. The first guide slope 6161 and the end face of the latch 64 facing the second limit button 616 cooperate to stop and abut, thereby driving the latch 64 to move from the third position to the fourth position, thereby driving the locking mechanism 6 to switch from the locked state to the unlocked state, thus releasing the sewage tank 5.

[0090] In some embodiments of the present invention, the switch assembly 61 further includes a fourth elastic element (not shown), one end of which is connected to the floor brush assembly 1, and the other end of which is connected to the latch 64, for driving the latch 64 to move from the fourth position to the third position.

[0091] Understandably, the fourth elastic element extends along the direction of movement of the latch 64. The fourth elastic element is located within the active channel 123 and at one end of the active channel 123 opposite to the first guide slope 6161. The fourth elastic element drives the latch 64 to move from the fourth position to the third position, thereby resetting the latch 64. At the same time, the resetting of the latch 64 can drive the second limit pedal 616 to move in the opposite direction (opposite to the user's pedaling direction), thereby resetting the second limit pedal 616 and enabling the next unlocking or locking operation.

[0092] When the sewage tank 5 needs to be released, the user steps on the second limit button 616. The first guide slope 6161 engages with the end face of the latch 64 facing the second limit button 616 to stop the latch, thereby driving the latch 64 to move from the third position to the fourth position, thus driving the locking mechanism 6 to switch from the locked state to the unlocked state, thereby releasing the sewage tank 5. At this time, the user releases the second limit button 616, and the fourth elastic element drives the latch 64 to move from the fourth position to the third position, thereby resetting the latch 64 and simultaneously resetting the second limit button 616.

[0093] When it is necessary to lock the sewage tank 5, the second limit button 616 is pressed again. The first guide slope 6161 engages with the end face of the latch 64 facing the second limit button 616, thereby driving the latch 64 from the third position to the fourth position. Then, the main body 2 switches from a lying position to an upright position. The pushing part 22 engages with the engaging slope 614, driving the pop-up bracket 615 from the second position to the first position. At this time, the second limit button 616 is released, and the fourth elastic element drives the latch 64 from the fourth position to the third position, thereby resetting the latch 64 and simultaneously resetting the second limit button 616. This achieves the locking of the latch 64 and the pop-up bracket 615, thus locking the sewage tank 5.

[0094] In some embodiments of the present invention, such as Figures 1-4 As shown, the first limit pedal 3 also includes a drive part 34, which is connected to the fixed part 31. The drive part 34 is adapted to abut against the second limit pedal 616. During the process of the second limit pedal 616 driving the locking mechanism 6 to switch from the locked state to the unlocked state, the second limit pedal 616 drives the drive part 34 to rotate the fixed part 31 so that the limit part 32 and the mating part 211 disengage.

[0095] It is understandable that, such as Figures 1-4As shown, the drive unit 34 is located at the upper end of the fixed part 31. When the user steps on the second limit button 616, the drive unit 34 can drive the fixed part 31 to rotate so that the limit part 32 and the mating part 211 are disengaged, thereby unlocking the main body 2 driven by the second limit button 616 and allowing the main body 2 to lie down. At the same time, when the user steps on the second limit button 616, the locking mechanism 6 can also be driven to switch from the locked state to the unlocked state, thereby releasing the sewage tank 5.

[0096] Therefore, by driving the second limit pedal 616, the main body 2 and the sewage tank 5 can be released simultaneously, which improves the unlocking efficiency of the cleaning device 10, reduces the unlocking steps, simplifies the unlocking process, and enhances the user experience.

[0097] Furthermore, by operating the first limit button 3 and the second limit button 616, the cleaning device 10 can have multiple unlocking states to meet various user needs, such as... Figures 1-4 In the example shown, the following two unlocked states of the cleaning device 10 can be achieved:

[0098] 1. The main body 2 is released and reclined, while the wastewater tank 5 is locked: The user steps on the foot pedal 33, and the end of the fixing part 31 furthest from the foot pedal 33 connects to the base plate of the floor brush assembly 1. The foot pedal 33 rotates downward, causing the first limit button 3 to rotate downward around the connection point between the fixing part 31 and the base plate of the floor brush assembly 1. This causes the limit part 32 to separate from the mating part 211, thereby unlocking the main body 2 and allowing it to recline backward. At this time, the wastewater tank 5 remains locked.

[0099] 2. Simultaneous release of the main body 2 and the sewage tank 5: When the user steps on the second limit button 616, the second limit button 616 moves downward, thereby driving the drive unit 34 to rotate the fixing part 31 so that the limit part 32 and the mating part 211 disengage, thereby unlocking and releasing the main body 2. At the same time, as the second limit button 616 moves downward, the drive locking mechanism 6 switches from the locked state to the unlocked state, thereby releasing the sewage tank 5.

[0100] In some embodiments of the present invention, such as Figures 1-4 As shown, the second limit pedal 616 has a second guide slope 6162 that abuts against the drive unit 34. When the drive locking mechanism 6 switches from the locked state to the unlocked state, the second guide slope 6162 tilts in the direction away from the limit unit 32 along the moving direction of the second limit pedal 616. Thus, the second guide slope 6162 makes the second limit pedal 616 drive the drive unit 34 more reliably and conveniently.

[0101] In some embodiments of the present invention, such as Figure 1 , Figure 5 , Figure 7 and Figure 10 As shown, the lower surface of the sewage tank 5 has a mounting part 51, and the upper surface of the floor brush assembly 1 has a mounting groove 11. The mounting part 51 is located in the mounting groove 11. The outer peripheral wall of the mounting part 51 has a limiting protrusion 52. In the locked state, the locking mechanism 6 cooperates with the limiting protrusion 52 to restrict the limiting protrusion 52 from moving upward.

[0102] It is understood that the mounting groove 11 can fix and install the mounting part 51 of the sewage tank 5, thereby restricting the movement of the sewage tank 5 in the radial direction along the mounting groove 11. The limiting protrusion 52 extends outward in the radial direction along the mounting part 51. In the locked state, the limiting protrusion 52 is restricted from moving upward, preventing the sewage tank 5 from moving upward and leaving the floor brush assembly 1, thereby improving the locking effect of the locking mechanism 6 in locking the sewage tank 5.

[0103] In addition, such as Figure 10 As shown, the inner wall of the mounting groove 11 has an extension hole 111. The spring tongue support 621 is movably disposed in the floor brush assembly 1. The locking spring tongue 623 is fixed on the spring tongue support 621 and passes through the extension hole 111.

[0104] In the locked state, the spring-loaded bracket 615 is in the first position, and the end of the spring tongue support 621 facing away from the mounting groove 11 abuts against the stop protrusion 611, thereby limiting the spring elastic element 622 from driving the spring tongue support 621 to move the locking spring tongue 623 in the direction away from the sewage tank 5, so that the locking spring tongue 623 passes through the protrusion hole 111, thereby making the locking spring tongue 623 cooperate with the limiting protrusion 52, limiting the upward movement of the limiting protrusion 52, so that the locking mechanism 6 can reliably lock the sewage tank 5.

[0105] In the locked state, the stop protrusion 611 and the lower side of the end of the spring tongue support 621 opposite to the mounting groove 11 abut against each other. The spring-loaded bracket 615 moves upward, so that the spring-loaded bracket 615 moves from the first position to the second position, so that the stop protrusion 611 can move upward and enter the mating groove 66. This makes the lower side of the end of the spring tongue support 621 opposite to the mounting groove 11 offset from the stop protrusion 611, so that the rebound elastic element 622 can drive the spring tongue support 621 to move in a direction away from the center of the mounting groove 11, so that the locking spring tongue 623 can move in a direction away from the center of the mounting groove 11, so that the locking spring tongue 623 and the limiting protrusion 52 are spaced apart in the radial direction of the mounting part 51, so that the locking mechanism 6 can release the sewage tank 5.

[0106] When the locking mechanism 6 moves from the locked state to the unlocked state, the spring-loaded bracket 615 moves upward, from the first position to the second position. The stop protrusion 611 also moves upward, so that the stop protrusion 611 enters the mating groove 66. At this time, the lower side of the end of the spring tongue support 621 away from the mounting groove 11 is offset from the stop protrusion 611. The rebound elastic element 622 can drive the spring tongue support 621 to move in a direction away from the center of the mounting groove 11, so that the locking spring tongue 623 can move in a direction away from the center of the mounting groove 11. This makes the locking spring tongue 623 and the limiting protrusion 52 separated in the radial direction of the mounting part 51, so that the locking mechanism 6 can release the sewage tank 5.

[0107] Furthermore, such as Figures 5-8 As shown, in the radially inward direction of the mounting groove 11, the upper end of the locking spring 623 is inclined downward, thereby forming a fourth guide slope 67. When the sewage tank 5 is installed, the limiting protrusion 52 on the mounting part 51 can be located at the lower end of the locking spring 623 through the fourth guide slope 67, thereby locking the sewage tank 5.

[0108] When the sewage tank 5 needs to be installed, there are two locking methods:

[0109] 1. The user first switches the main body 2 from a horizontal position to an upright position, causing the pushing part 22 to abut against the mating inclined surface 614, thereby driving the pop-up bracket 615 to move from the second position to the first position. The pop-up bracket 615 moves downward, and the stop protrusion 611 also moves downward, causing the stop protrusion 611 to leave the mating groove 66. At this time, the end of the spring tongue support 621 away from the mounting groove 11 abuts against the stop protrusion 611, and the spring tongue support 621 moves towards the center of the mounting groove 11. The spring elastic element 622 is compressed, allowing the locking spring tongue 623 to move towards the center of the mounting groove 11. The locking mechanism 6 returns to the locked state. At this time, the sewage tank is... 5. When installed onto the floor brush assembly 1, during this process, the limiting protrusion 52 on the mounting part 51 moves toward the bottom wall of the mounting groove 11 and contacts the fourth guide slope 67, driving the locking spring 623 to move away from the center of the mounting groove 11, thereby causing the second elastic member 624 to contract, allowing the limiting protrusion 52 to continue moving toward the bottom wall of the mounting groove 11 until the limiting protrusion 52 is located at the lower end of the locking spring 623. At this time, the second elastic member 624 extends, driving the locking spring 623 to move toward the center of the mounting groove 11, thereby causing the lower surface of the locking spring 623 and the upper surface of the limiting protrusion 52 to abut against each other, thereby locking the sewage tank 5.

[0110] 2. The user first installs the sewage tank 5 onto the floor brush assembly 1. At this time, the mounting part 51 is located in the mounting groove 11. Then, the main body 2 is switched from a horizontal position to an upright position, so that the pushing part 22 stops against the mating inclined surface 614, thereby driving the pop-up bracket 615 to move from the second position to the first position. The pop-up bracket 615 moves downward, and the stop protrusion 611 also moves downward, so that the stop protrusion 611 leaves the mating groove 66. At this time, the end of the spring tongue support 621 away from the mounting groove 11 stops against the stop protrusion 611. The spring tongue support 621 moves towards the center of the mounting groove 11, and the rebound elastic element 622 is compressed, so that the locking spring tongue 623 can move towards the center of the mounting groove 11. The locking mechanism 6 returns to the locked state, realizing the locking of the sewage tank 5.

[0111] Therefore, whether the pushing part 22 is pushed to stop the engagement with the inclined surface 614 before installing the sewage tank 5, or the sewage tank 5 is installed first and then the pushing part 22 is pushed to stop the engagement with the inclined surface 614, locking of the sewage tank 5 can be achieved. This improves the fault tolerance of the sewage tank 5 installation and increases installation efficiency.

[0112] In some embodiments of the present invention, such as Figure 1 and Figure 10 As shown, the lower surface of the sewage tank 5 has a positioning boss 52, and the upper surface of the floor brush assembly 1 has a positioning groove 14 that mates with the positioning boss 52. It can be understood that the positioning groove 14 is used to place the positioning boss 52, thereby improving the installation reliability of the sewage tank 5 and the floor brush assembly 1. At the same time, the positioning groove 14 is connected to the mounting groove 11, which simplifies the structure.

[0113] The cleaning device 10 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings. It is to be understood that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0114] like Figures 1-4 As shown, the cleaning device 10 according to an embodiment of the present invention includes a floor brush assembly 1, a main body 2, a first limiting button 3, a first elastic element, a wastewater tank 5, a locking mechanism 6, and a second limiting button 616.

[0115] like Figures 1-4As shown, the lower end of the main body 2 is provided with a rotating shaft 21, and the main body 2 has a pushing part 22. The rotating shaft 21 is rotatably connected to the floor brush assembly 1. The outer peripheral wall of the rotating shaft 21 is provided with a mating part 211. The first limiting button 3 includes a fixing part 31, a limiting part 32, a stepping part 33 and a driving part 34. One end of the fixing part 31 is rotatably connected to the floor brush assembly 1. The limiting part 32 is connected to the fixing part 31. The stepping part 33 is connected to the fixing part 31. When the limiting part 32 is limited and engaged with the mating part 211, the main body 2 remains upright. When the limiting part 32 rotates with the fixing part 31 and disengages from the mating part 211, the main body 2 can rotate with the rotating shaft 21. One end of the first elastic member is connected to the first limiting button 3, and the other end is connected to the floor brush assembly 1. It is used to drive the limiting part 32 to rotate toward the rotating shaft 21. The driving part 34 is connected to the fixing part 31.

[0116] like Figures 5-8 As shown, the wastewater tank 5 is mounted on the floor brush assembly 1. The lower end of the wastewater tank 5 has a mounting part 51. The outer peripheral wall of the mounting part 51 has a limiting protrusion 52. The upper surface of the floor brush assembly 1 has a mounting groove 11. The mounting part 51 is located in the mounting groove 11. The locking mechanism 6 is mounted on the floor brush assembly 1. The locking mechanism 6 has a locking state for limiting the wastewater tank 5 and an unlocking state for releasing the wastewater tank 5. In the locking state, the locking mechanism 6 cooperates with the limiting protrusion 52 to restrict the limiting protrusion 52 from moving upward.

[0117] like Figures 5-11 As shown, the locking mechanism 6 includes a locking component 62 and a switch component 61. The locking component 62 is installed on the floor brush assembly 1, and the wastewater tank 5 can be locked onto the floor brush assembly 1 by the locking component 62. The switch component 61 is installed on the floor brush assembly 1 and connected to the locking component 62. The switch component 61 is used to control the locking component 62 to unlock the wastewater tank 5.

[0118] like Figures 5-11 As shown, the locking assembly 62 includes: a spring-loaded support 621, a locking spring 623, a second elastic element 624, and a return elastic element 622. The spring-loaded support 621 is movably disposed within the floor brush assembly 1. The end of the spring-loaded support facing away from the wastewater tank 5 is adapted to abut against the switch assembly 61. When the wastewater tank 5 is unlocked, the switch assembly 61 can provide space for the spring-loaded support 621 to move in the direction away from the wastewater tank 5. The locking spring 623 is fixed on the spring-loaded support 621 and is used to lock the wastewater tank 5. The return elastic element 622 is disposed within the floor brush assembly 1 and is used to drive the spring-loaded support 621 to move the locking spring 623 in the direction away from the wastewater tank 5. One end of the second elastic element 624 is connected to the spring-loaded support 621, and the other end is connected to the locking spring 623, and is used to drive the locking spring 623 to move towards the wastewater tank 5.

[0119] like Figures 5-12As shown, the switch assembly 61 includes: a pop-up bracket 615, a second limit button 616, a third elastic element 63, a latch 64, and a fourth elastic element.

[0120] like Figures 5-11 As shown, the pop-up bracket 615 is rotatably disposed within the floor brush assembly 1 and has a first position and a second position. The pop-up bracket 615 has a stop protrusion 611. In the locked state, the pop-up bracket 615 is located in the first position, and the stop protrusion 611 abuts against the locking mechanism 6. In the unlocked state, the pop-up bracket 615 is located in the second position, and the stop protrusion 611 is offset from the locking mechanism 6. The pop-up bracket 615 is rotatably disposed within the floor brush assembly 1. One end of the third elastic member 63 is connected to the floor brush assembly 1, and the other end is connected to the pop-up bracket 615, which is used to drive the pop-up bracket 615 to rotate from the first position to the second position. The end of the pop-up bracket 615 away from the rotation axis of the pop-up bracket 615 has a mating inclined surface 614. When the main body 2 switches to an upright state, the pushing part 22 abuts against the mating inclined surface 614, which is used to drive the pop-up bracket 615 to move from the second position to the first position.

[0121] like Figures 5-12 As shown, the latch 64 is movably disposed within the floor brush assembly 1. The latch 64 has a third position and a fourth position. In the locked state, the latch 64 is located in the third position and is engaged with the pop-up bracket 615. In the unlocked state, the latch 64 is located in the fourth position and is disengaged from the pop-up bracket 615. One end of the fourth elastic member is connected to the floor brush assembly 1, and the other end of the fourth elastic member is connected to the latch 64, which is used to drive the latch 64 to move from the fourth position to the third position.

[0122] like Figures 5-12 As shown, the second limit pedal 616 is used to drive the latch 64 to move from the third position to the fourth position so as to drive the locking mechanism 6 to switch from the locked state to the unlocked state. The second limit pedal 616 has a first guide slope 6161 that abuts against the latch 64 and a second guide slope 6162 that abuts against the drive part 34. During the process of driving the locking mechanism 6 to switch from the locked state to the unlocked state, the first guide slope 6161 is inclined in the direction away from the latch 64 along the moving direction of the second limit pedal 616. The drive part 34 is adapted to abut against the second limit pedal 616. When the second limit pedal 616 drives the locking mechanism 6 to switch from the locked state to the unlocked state, the second limit pedal 616 drives the drive part 34 to rotate the fixing part 31 so that the limiting part 32 and the cooperating part 211 are disengaged. When the locking mechanism 6 is driven to switch from the locked state to the unlocked state, the second guide slope 6162 is inclined in the direction away from the limiting part 32 along the moving direction of the second limit pedal 616.

[0123] By operating the first limit button 3 and the second limit button 616, the cleaning device 10 can have multiple unlocking states to meet various user needs, such as... Figures 1-4 In the example shown, the following two unlocked states of the cleaning device 10 can be achieved:

[0124] 1. The main body 2 is released and reclined, while the wastewater tank 5 is locked: The user steps on the foot pedal 33, and the end of the fixing part 31 furthest from the foot pedal 33 connects to the base plate of the floor brush assembly 1. The foot pedal 33 rotates downward, causing the first limit button 3 to rotate downward around the connection point between the fixing part 31 and the base plate of the floor brush assembly 1. This causes the limit part 32 to separate from the mating part 211, thereby unlocking the main body 2 and allowing it to recline backward. At this time, the wastewater tank 5 remains locked.

[0125] 2. Simultaneous release of the main body 2 and the sewage tank 5: When the user steps on the second limit button 616, the second limit button 616 moves downward, thereby driving the drive unit 34 to rotate the fixing part 31 so that the limit part 32 and the mating part 211 disengage, thereby unlocking and releasing the main body 2. At the same time, as the second limit button 616 moves downward, the drive locking mechanism 6 switches from the locked state to the unlocked state, thereby releasing the sewage tank 5.

[0126] When it is necessary to lie down on the main body 2, the user steps on the foot pedal 33, and the foot pedal 33 moves in the direction of lying down on the main body 2 (e.g., in...). Figure 2 The first limit button 3 rotates counterclockwise (as shown in the diagram), causing the first limit button 3 to rotate around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 towards the lying position of the main body 2. This causes the limit part 32 to rotate away from the rotating shaft 21, thus separating the limit part 32 from the mating part 211. During this process, the first elastic element contracts, and the main body 2 is unlocked. The user lays the main body 2 down, and the rotating shaft 21 rotates accordingly. The mating part 211 rotates towards the lying position of the main body 2, releasing the foot pedal 33. At this time, the first elastic element extends, driving the limit part 32 to rotate towards the rotating shaft 21, so that the first limit button 3 remains upright, completing the unlocking and lying down of the main body 2.

[0127] The first method for changing the main body 2 from a lying position to an upright position is as follows: When it is necessary to maintain the upright position of the main body 2 (from the lying position to the upright position), the first limit button 3 is in the upright position. The user steps on the foot pedal 33, which rotates in the lying direction of the main body 2. This causes the first limit button 3 to rotate around the connection point between the fixing part 31 and the bottom plate of the floor brush assembly 1 in the lying direction of the main body 2. This causes the limiting part 32 to rotate in a direction away from the rotating shaft 21. During this process, the first elastic element contracts, changing the main body 2 from a lying position to an upright position. The rotating shaft 21 rotates accordingly, and the mating part 211 rotates in the vertical direction of the main body 2. Then, the foot pedal 33 is released, and the first elastic element extends, driving the limiting part 32 to rotate in the direction of the rotating shaft 21. This causes the limiting part 32 to engage with the mating part 211, thereby locking the first limit button 3.

[0128] The second method for the main body 2 to change from a lying position to an upright position: When it is necessary to keep the main body 2 in an upright position (from the lying position to the upright position), the first limit button 3 is in an upright position. The user drives the main body 2 from the lying position to the upright position, and the rotating shaft 21 rotates accordingly. The mating part 211 rotates in the vertical direction of the main body 2. The mating part 211 is directly located on the side of the limit part 32 away from the bottom plate of the floor brush assembly 1 through the third guide slope 321 of the limit part 32, thereby locking the main body 2 in the upright position.

[0129] When the sewage tank 5 needs to be installed, there are two locking methods:

[0130] 1. The user first switches the main body 2 from a horizontal position to an upright position, causing the pushing part 22 to abut against the mating inclined surface 614, thereby driving the pop-up bracket 615 to move from the second position to the first position. The pop-up bracket 615 moves downward, and the stop protrusion 611 also moves downward, causing the stop protrusion 611 to leave the mating groove 66. At this time, the end of the spring tongue support 621 away from the mounting groove 11 abuts against the stop protrusion 611, and the spring tongue support 621 moves towards the center of the mounting groove 11. The spring elastic element 622 is compressed, allowing the locking spring tongue 623 to move towards the center of the mounting groove 11. The locking mechanism 6 returns to the locked state. At this time, the sewage tank is... 5. When installed onto the floor brush assembly 1, during this process, the limiting protrusion 52 on the mounting part 51 moves toward the bottom wall of the mounting groove 11 and contacts the fourth guide slope 67, driving the locking spring 623 to move away from the center of the mounting groove 11, thereby causing the second elastic member 624 to contract, allowing the limiting protrusion 52 to continue moving toward the bottom wall of the mounting groove 11 until the limiting protrusion 52 is located at the lower end of the locking spring 623. At this time, the second elastic member 624 extends, driving the locking spring 623 to move toward the center of the mounting groove 11, thereby causing the lower surface of the locking spring 623 and the upper surface of the limiting protrusion 52 to abut against each other, thereby locking the sewage tank 5.

[0131] 2. The user first installs the sewage tank 5 onto the floor brush assembly 1. At this time, the mounting part 51 is located in the mounting groove 11. Then, the main body 2 is switched from a horizontal position to an upright position, so that the pushing part 22 stops against the mating inclined surface 614, thereby driving the pop-up bracket 615 to move from the second position to the first position. The pop-up bracket 615 moves downward, and the stop protrusion 611 also moves downward, so that the stop protrusion 611 leaves the mating groove 66. At this time, the end of the spring tongue support 621 away from the mounting groove 11 stops against the stop protrusion 611. The spring tongue support 621 moves towards the center of the mounting groove 11, and the rebound elastic element 622 is compressed, so that the locking spring tongue 623 can move towards the center of the mounting groove 11. The locking mechanism 6 returns to the locked state, realizing the locking of the sewage tank 5.
