[0061] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0062] This application provides a wastewater tank locking assembly 400, such as... Figure 1 As shown, it includes: two symmetrically arranged movable panels 1 and an operation button 2.

[0063] like Figure 1 , Figure 2As shown, the movable plate 1 includes a plate body 11, a claw 12, and a wedge block 13. The claw 12 is located on one side of the plate body 11 along the X direction and is used to engage the sewage tank 200. The wedge block 13 has a first inclined surface 131, which extends along the X direction and the Z direction, with the Z direction perpendicular to the X direction.

[0064] like Figure 1 , Figure 3 As shown, the operation button 2 can move along the Z direction when it is operated. The operation button 2 has two symmetrically arranged second inclined surfaces 21, which extend along the X and Z directions. The two second inclined surfaces 21 respectively cooperate with the first inclined surfaces 131 of the two movable plates 1.

[0065] The movable plate 1 can move along the X direction under the action of the operation button 2; when the operation button 2 is in the initial position, the movable plate 1 is in the engaged position and the claw 12 is engaged with the sewage tank 200; when the operation button 2 is operated to the pressed position, the movable plate 1 is in the retracted position and the claw 12 is separated from the sewage tank 200.

[0066] like Figure 4 As shown, this embodiment provides a cleaning brush that includes the wastewater tank locking assembly 400 of this embodiment. The cleaning brush also includes a brush frame 100 and a wastewater tank 200.

[0067] The wastewater tank locking assembly 400 is fixed inside the floor brush frame 100, and the wastewater tank 200 can be installed in the floor brush frame 100. The side wall of the wastewater tank 200 has a snap-in hole 201 corresponding to the claw 12, which allows for insertion via... Figure 1 The claw 12 shown engages with the insertion hole 201, allowing the wastewater tank 200 to be fixed with the wastewater tank locking assembly 400.

[0068] The wastewater tank locking assembly 400 provided in this embodiment can lock and fix the wastewater tank 200 in place via the claws 12 on the movable plate 1. The movable plate 1 is connected to the operation button 2 and can move along the X direction under the action of the operation button 2. When the operation button 2 is in the initial position, the movable plate 1 is in the engaged position, and the claws 12 are engaged with the wastewater tank 200. When the operation button 2 is operated to the pressed position, the movable plate 1 is in the retracted position, the claws 12 are separated from the wastewater tank 200, and the wastewater tank 200 can be easily removed from the floor brush frame 100. Therefore, the wastewater tank locking assembly and cleaning floor brush provided in this embodiment can achieve one-button separation of the wastewater tank 200 without the need for two-handed operation, making operation simple and preventing hands from getting dirty, thus bringing convenience to the user.

[0069] The sewage tank locking assembly 400 provided in this embodiment operates through the following movement stages:

[0070] (1) Under normal circumstances, such as Figures 5-6As shown, the operation button 2 is in the initial position, and the movable plate 1 is in the engaged position. At this time, the claw 12 can engage with the sewage tank 200. The second inclined surface 21 of the operation button 2 cooperates with the first inclined surface 131 of the movable plate 1. Since both the second inclined surface 21 and the first inclined surface 131 are surfaces extending along the X and Z directions, it can be understood that when the operation button 2 is pressed, the movement of the operation button 2 along the Z direction can drive the movable plate 1 to move along the X direction.

[0071] (2) After the user presses operation button 2, as follows Figures 8-9 As shown, when the operation button 2 is in the pressed position and the movable plate 1 is in the retracted position, the claw 12 is separated from the sewage tank 200, and the sewage tank 200 is in a removable state.

[0072] In an alternative embodiment, such as Figure 1 As shown, the sewage tank locking assembly 400 also includes a locking assembly 3; the locking assembly 3 can lock the movable plate 1 when it reaches the retracted position, thereby restricting the movement of the movable plate 1 in the X direction. In this embodiment, by locking the movable plate 1 in the retracted position through the locking assembly 3, the claw 12 is kept separated from the sewage tank 200, ensuring that the user has enough time to disassemble the sewage tank 200 and reducing the difficulty of user operation. It is understood that the locking assembly 3 can also be designed to lock with the operation button 2. Since the position of the operation button 2 determines the position of the movable plate 1, the movable plate 1 can be indirectly locked.

[0073] In an alternative embodiment, such as Figure 5 As shown, the locking component 3 is installed on one side of the plate 11 along the Y direction, where the Y direction is perpendicular to the X direction; as Figure 11 As shown, the locking component 3 includes a component body 31 and a locking tongue 32. The locking tongue 32 is connected to the component body 31 and can move along the Y direction.

[0074] like Figure 2 As shown, the plate 11 has a slot 111 on one side along the Y direction. When the locking tongue 32 is at least partially engaged in the slot 111, it can restrict the movement of the movable plate 1 along the X direction. When the locking tongue 32 is disengaged from the slot 111, it can release the restriction on the movement of the movable plate 1.

[0075] This embodiment provides a locking component 3, the principle of which involves the following movement stages:

[0076] (1) Under normal circumstances, such as Figures 5-6 As shown, operation button 2 is in the initial position, and movable plate 1 is in the engaged position. At this time, the claw 12 can engage with the sewage tank 200; Figure 7 As shown, the locking tongue 32 is located outside the slot 111, and the slot 111 is located on one side of the locking tongue 32 along the X direction;

[0077] (2) After the user presses operation button 2, as follows Figures 8-9 As shown, operation button 2 is in the pressed position, and movable plate 1 is in the retracted position. At this time, the claw 12 is separated from the sewage tank 200, and the sewage tank 200 is in a removable state. Figure 10 As shown, the locking tongue 32 is engaged in the slot 111, thus restricting the movement of the movable plate 1 in the X direction and achieving initial separation of the sewage tank 200.

[0078] In an optional embodiment, the component body 31 is movable along the Z-direction, and the locking tongue 32 is movably connected to the component body 31. When the component body 31 moves along the Z-direction, it can cause the locking tongue 32 to disengage from the slot 111. Figure 10 As shown, the locking tongue 32 engages in the slot 111, restricting the movement of the movable plate 1 in the X direction. Figures 12-14 As shown, when the main body 31 of the component moves along the Z direction, the locking tongue 32 disengages from the slot 111, and the locking tongue 32 releases the restriction on the movement of the movable plate 1 in the X direction, so that the movable plate 1 and the operation button 2 can be restored to an operable state.

[0079] In an alternative embodiment, such as Figure 11 As shown, the main body 31 of the component has a mounting cavity 311, and an opening 312 on one side of the mounting cavity 311. The main body of the locking tongue 32 is installed in the mounting cavity 311, and the end of the locking tongue 32 can extend or retract from the opening 312. In this embodiment, the mounting cavity 311 facilitates the installation of the locking tongue 32, allows the locking tongue 32 to move in the Z direction with the main body 31 of the component, and the locking tongue 32 can also extend or retract from the opening 312 through its end, thus extending into or retracting from the slot 111.

[0080] In an alternative embodiment, such as Figure 11 As shown, the locking assembly 3 includes a first elastic element 33, which is installed in the mounting cavity 311 and abuts against one side of the locking tongue 32 so that the end of the locking tongue 32 remains protruding from the opening 312 when no external force is applied. In this embodiment, the first elastic element 33 ensures that the locking tongue 32 always tends to move towards the movable plate 1 in the Y direction, thus automatically engaging with the slot 111 when the locking tongue 32 is aligned with the slot 111 in both the X and Z directions. This design allows the locking tongue 32 to automatically engage with the slot 111 after the user presses the operation button 2, restricting the movement of the movable plate 1 in the X direction and facilitating the user to remove the sewage tank 200 at any time.

[0081] In an alternative embodiment, such as Figure 11As shown, the end of the latch 32 has a third inclined surface 321, which extends along the Y and Z directions. When the latch 32 moves along the Z direction under the drive of the component body 31, the latch 32 can move along the Y direction away from the slot 111 under the pressure of the edge of the slot 111. Figure 14 As shown, when the main body 31 moves downward along the Z direction, due to the structure of the third inclined surface 321 extending along the Y and Z directions, the locking tongue 32 can move along the Y direction under the pressure of the edge of the slot 111, so that the locking tongue 32 can be disengaged from the slot 111 and the movable plate 1 can be unlocked.

[0082] In an alternative embodiment, such as Figure 2 , Figure 14 As shown, the edge of the slot 111 has a fourth inclined surface 1111 corresponding to the third inclined surface 321. In this embodiment, the fourth inclined surface 1111 is designed to extend along the Y and Z directions corresponding to the third inclined surface 321, which stabilizes the direction of the force exerted on the latch 32 and makes the movement of the latch 32 smoother.

[0083] In an alternative embodiment, such as Figure 15 As shown, the wastewater tank locking assembly 400 also includes a mounting base plate 4, which includes a groove 41 and a mounting hole 42. The groove 41 extends along the X direction, and the mounting hole 42 extends along the Z direction. Figure 5 As shown, the plate 11 is movably mounted in the slide groove 41, and the component body 31 is movably mounted in the mounting hole 42. In this embodiment, the mounting base plate 4 facilitates the installation of the movable plate 1 and the locking component 3, as well as their movement in a specific direction.

[0084] In an alternative embodiment, such as Figure 11 As shown, the sewage tank locking assembly 400 also includes a second elastic member 34, which abuts against one end of the assembly body 31 along the Z direction, so that the assembly body 31 can move in the positive Z direction when no external force is applied. Figure 11 (Middle is downward). The function of the second elastic element 34 is to provide the main body of the component 31 with a positive elastic force in the Z direction under normal conditions, so that the main body of the component 31 can move automatically in the positive Z direction instantly when the obstruction is removed.

[0085] like Figure 11 , Figure 14 As shown, the sidewall of the component body 31 has a protrusion 313, which abuts against the edge of the mounting hole 42 to limit the distance the component body 31 can move in the positive direction along the Z direction, such as... Figure 14 As shown, when the protrusion 313 abuts against the edge of the mounting hole 42, the component body 31 moves the maximum distance in the positive direction along the Z direction, and the locking tongue 32 and the slot 111 are separated by a preset distance in the Z direction.

[0086] In an alternative embodiment, such as Figure 2 As shown, in this embodiment, the plate 11 has a flat surface 112 on one side in the Y direction, and the slot 111 is opened within the flat surface 112. Therefore, when the latch 32 disengages from the slot 111, as the movable plate 1 moves in the X direction, or the component body 31 moves in the Z direction, the end of the latch 32 will abut against the flat surface 112, and the flat surface 112 and the latch 32 do not conflict in the direction of movement.

[0087] In an alternative embodiment, such as Figure 5 As shown, the sewage tank locking assembly 400 also includes a third elastic element 5, such as... Figure 15 As shown, a support block 43 is provided on the mounting base plate 4, and the two ends of the third elastic member 5 abut against the support block 43 and the movable plate 1 respectively. When the movable plate 1 is in the retracted position, the third elastic member 5 is in a compressed state, and the third elastic member 5 can drive the movable plate 1 back to the engaging position through elastic force. In this embodiment, the function of the third elastic member 5 is to drive the movable plate 1 to automatically return to the engaging position, so that the claw 12 can keep it engaged in the engaging hole 201 of the sewage tank 200.

[0088] In an alternative embodiment, such as Figure 4 As shown, the cleaning brush in this embodiment also includes a top cover 300, which is fixed to one side of the brush frame 100 along the Z direction. The two ends of the second elastic member 34 respectively abut against the component body 31 and the top cover 300. When the wastewater tank 200 is separated from the brush frame 100, the component body 31 moves to the pop-out position under the elastic force of the second elastic member 34. When the component body 31 is in the pop-out position, one end of its positive Z-direction protrudes from the surface of the mounting base plate 4. When the wastewater tank 200 is assembled with the brush frame 100, the component body 31 moves to the locking height under the squeezing action of the wastewater tank 200. When the component body 31 is in the locking height, as shown... Figure 7 As shown, the locking tongue 32 and the slot 111 are aligned in the Z direction. Therefore, the design of the sewage tank 200 in this embodiment can create a linkage with the component body 31. When the sewage tank 200 is removed, the component body 31 can move to the pop-out position under the elastic force of the second elastic element 34. Otherwise, the component body 31 cannot move to the limit position, and the locking tongue 32 cannot disengage from the slot 111. When the sewage tank 200 is reinstalled, the locking tongue 32 and the slot 111 are aligned in the Z direction. In this way, the locking tongue 32 and the slot 111 are only misaligned in the Y and X directions. When the user presses the operation button 2 with the locking tongue 32, the locking tongue 32 will re-engage in the slot 111.

[0089] In an alternative embodiment, such as Figure 4 As shown, the sewage tank 200 includes a compression panel 202, which facilitates compression of one end of the main body 31 in the Z direction, causing it to move in the opposite direction of the Z direction.

[0090] In an alternative embodiment, such as Figure 2 As shown, the plate 11 is L-shaped, with the length of the first part along the X direction and the width of the second part along the X direction. The claws 12 are located in the second part, and two claws are arranged along the Y direction, corresponding to... Figure 4 The slots 201 at the two corners on both sides of the sewage tank 200 shown are designed to allow for a more balanced engagement of the sewage tank 200. It is understood that the number of slots 12 arranged along the Y direction is not limited to two; it can be one, three, four, or more.

[0091] In an optional embodiment, the maximum travel distance of the movable plate 1 driven by the operation button 2 along the X direction is L1. The movable plate 1 is designed to be locked by the locking component 3 after moving L2 along the X direction from the engaged position. The claw 12 is designed to disengage from the sewage tank 200 after moving L3 along the X direction from the engaged position. L1 > L2 > L3, to achieve the following effects:

[0092] 1. The maximum travel redundancy of the movable plate 1 ensures that after pressing the operation button 2, the movable plate 1 can successively reach the position of disengaging from the sewage tank and the position of locking with the locking component 3.

[0093] 2. When the movable plate 1 moves L3 from the engaged position along the X direction, it can prevent the movable plate 1 from being locked.
