[0018] The technical solution of the present invention has the following advantages:

[0019] The sewage tank assembly of the cleaning device provided by the present invention has a structure in which, when the scrubber is upright and the housing is in a first upright position, the fan is operated to create a negative pressure inside the housing, causing sewage to enter the housing through the sewage inlet. Since the housing is upright, the sewage will not flow upward onto the fan, but will be stored inside the housing, and air will be discharged outside the housing after passing through the air duct outlet. When the scrubber is in a 180-degree flat mopping position, the housing is in a second horizontal position. At this time, the sewage in the housing may flow horizontally toward the air duct outlet and then onto the fan. Therefore, the present application provides a hanging plate. When the housing is in the second position, the driving structure drives the hanging plate to rotate to the first position. At this time, the hanging plate can block the sewage from flowing toward the air duct outlet, thereby preventing the sewage from rushing into the fan and damaging the fan. Therefore, the sewage tank assembly can achieve a 180-degree flat mopping function. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] Floor scrubbers with wastewater tanks, especially those with water spray functions, are widely popular because they offer more efficient floor cleaning. A floor scrubber typically consists of a motor (which acts as a vacuum source), a clean water tank, a wastewater tank, a water spray system connected to the clean water tank, and a recovery system connected to the wastewater tank. The motor is located above the wastewater tank. During operation, the water spray system sprays clean water onto the floor to wet any contaminants, while the recovery system draws wastewater back into the wastewater tank. Furthermore, the recovery system can also clean any existing wastewater on the floor.

[0035] Because when the handle of the floor scrubber is tilted significantly toward the floor, water in the sewage tank provided in the handle may enter the motor and damage the motor, the floor scrubber in the prior art cannot achieve a 180-degree flat mopping function.

[0036] To this end, this embodiment provides a sewage tank assembly for a cleaning device, wherein the cleaning device is preferably a floor scrubber.

[0037] In one embodiment, Figures 1 to 6 As shown, the sewage tank assembly includes a tank body 1, a hanging plate 3 and a driving structure.

[0038] Among them, the first end of the box body 1 has a sewage inlet 101, and the second end of the box body 1 is the air duct outlet. The first end is preferably the bottom of the box body 1, and the second end is preferably the top of the box body 1. The outside of the second end of the box body 1 is suitable for arranging a fan 2. When the fan 2 is working, it can allow sewage to enter the box body 1 from the sewage inlet 101. The box body 1 has a first state of upright placement and a second state of horizontal placement; the hanging plate 3 is rotatably arranged in the box body 1, and the hanging plate 3 has a first position of blocking part of the channel between the sewage inlet 101 and the air duct outlet, and a second position of clearing the channel between the sewage inlet 101 and the air duct outlet; the driving structure is connected to the hanging plate 3. When the box body 1 is in the first state, the driving structure drives the hanging plate 3 to rotate to the second position. When the box body 1 is in the second state, the driving structure drives the hanging plate 3 to rotate to the first position.

[0039] In this embodiment, when the floor scrubber is upright, the box body 1 is in a first state of upright placement, and the operation of the fan 2 can make the box body 1 in a negative pressure state, so that the sewage enters the box body 1 through the sewage inlet 101. Since the box body 1 is placed upright, the sewage will not flow upwards to the fan 2, and the sewage will be stored in the box body 1. The air is discharged to the outside of the box body 1 after passing through the air duct outlet; when the floor scrubber is in a 180-degree flat dragging state, the box body 1 is in a second state of horizontal placement. At this time, the sewage in the box body 1 may flow horizontally toward the air duct outlet and then flow onto the fan 2. Therefore, by providing a hanging plate 3, when the box body 1 is in the second state, the driving structure drives the hanging plate 3 to rotate to the first position. At this time, the hanging plate 3 blocks part of the channel between the sewage inlet 101 and the air duct outlet. The sewage can still enter the box body 1 from the sewage inlet 101 under the action of the fan 2. At this time, the hanging plate 3 can block the sewage from flowing toward the air duct outlet, thereby preventing the sewage from rushing into the fan 2 and damaging the fan 2. Therefore, the sewage tank assembly can achieve a 180-degree flat mopping function.

[0040] It should be noted that a sponge assembly 4 is provided at the air duct outlet to filter dirt and prevent it from flowing out of the housing 1. The fan 2 is located on the side of the sponge assembly 4 away from the sewage inlet 101. The specific structure and location of the sponge assembly 4 and the fan 2 are not the focus of this embodiment and are therefore not described in detail.

[0041] like Figure 1 As shown, a sewage inlet pipe 102 is provided in the box body 1, and the first end of the sewage inlet pipe 102 constitutes a sewage inlet. The hanging plate 3 is close to the second end of the sewage inlet pipe 102. The sewage enters the box body 1 through the sewage inlet pipe 102 under the action of vacuum suction, and then flows around the second end of the sewage inlet pipe 102 and is stored in the sewage tank.

[0042] Based on the above embodiment, in a preferred embodiment, when the housing 1 is in a first state in which the housing 1 is placed upright, the first position is perpendicular to the height direction of the housing 1, and the second position is parallel to the height direction of the housing 1. It should be noted that the height direction of the housing 1 is the vertical direction of the housing 1 when the housing 1 is placed upright. Specifically, when the housing 1 is in the first state, the hanging plate 3 is in a vertical position and does not affect the flow of air within the housing 1. When the housing 1 is in the second state, the driving structure drives the hanging plate 3 to rotate to a vertical position, at which point the hanging plate 3 can block the flow of sewage toward the fan 2. In other alternative embodiments, the first position forms a certain angle with the vertical direction, the angle being less than 90° or greater than 90°, and the second position forms a certain angle with the vertical direction, the angle being less than 90° or greater than 90°. That is, when the housing 1 is in the first state, the hanging plate 3 is not in a vertical position, and when the housing 1 is in the second state, the hanging plate 3 is also not in a vertical position.

[0043] Based on the above embodiment, in a preferred embodiment, when the hanging plate 3 is in the first position, the cross-section of the housing 1 is divided into a first area and a second area at the hanging plate 3. The hanging plate 3 seals the first area, while the second area allows fluid communication between the first end and the second end. In this embodiment, when the floor scrubber is mopping 180 degrees horizontally, the hanging plate 3 only seals the first area, leaving the second area unsealed. This does not affect the normal flow of air, and still ensures that sewage can enter the housing 1 through the sewage inlet 101.

[0044] It should be noted that when the floor scrubber is mopping 180 degrees, the first area is located below the second area, and the sewage in the box 1 accumulates in the first area below, thereby preventing the sewage from flowing through the second area to the air duct outlet and then flowing onto the fan 2.

[0045] Based on the above embodiment, in a preferred embodiment, the drive structure is a drive motor 5. In this embodiment, the drive structure is simple and easy to control. In other alternative embodiments, the drive structure may include a drive motor 5 and a transmission assembly connected between the drive motor 5 and the hanging plate 3.

[0046] Based on the above embodiment, in a preferred embodiment, the hanging plate 3 includes a plate body 301 and a rotating shaft 302 connected to the plate body 301. The output shaft of the drive motor 5 is connected to the rotating shaft 302 via a coupling 13. In this embodiment, the output shaft of the drive motor 5 is connected to the rotating shaft 302 via the coupling 13, and the output shaft of the drive motor 5 is firmly connected to the rotating shaft 302. In other alternative embodiments, the output shaft of the drive motor 5 may be directly connected to the rotating shaft 302.

[0047] Based on the above embodiment, in a preferred embodiment, the housing 1 is provided with a hinge hole 103, and the hanging plate 3 is provided with two coaxial rotating shafts 302, one of which is connected to the output shaft of the drive motor 5, and the other is rotatably disposed in the hinge hole 103. In this embodiment, by connecting one of the rotating shafts 302 to the output shaft of the drive motor 5 and the other rotatably disposed in the hinge hole 103, the position of the hanging plate 3 is ensured to be stable and will not deflect during rotation. In an alternative embodiment, only one rotating shaft 302 may be connected to the plate 301, and an axial hole is provided on the other side of the plate 301 at a position coaxial with the rotating shaft 302, and a hinge shaft adapted to the axial hole is provided on the housing 1. This can also ensure that the position of the hanging plate 3 is stable and will not deflect during rotation.

[0048] Based on the above embodiment, in a preferred embodiment, a motor mounting groove 104 is provided on the housing 1, and the drive motor 5 is disposed in the motor mounting groove 104. In this embodiment, by providing the motor mounting groove 104 on the housing 1, it is convenient to install and fix the drive motor 5, and the provision of the motor mounting groove 104 can also prevent sewage from entering the motor mounting groove 104.

[0049] like Figure 3 As shown, the motor installation groove 104 is formed by the outer wall of the box body 1 being recessed inwardly, and the output shaft of the driving motor 5 passes through the bottom of the motor installation groove 104 and is sealed with the bottom of the groove.

[0050] Based on the above embodiment, in a preferred embodiment, a sealing cover 6 is fixedly provided at the notch of the motor mounting groove 104. In this embodiment, by providing the sealing cover 6, the drive motor 5 can be sealed in the motor mounting groove 104 and the position of the drive motor 5 can be fixed.

[0051] Specifically, the sealing cover 6 is installed at the notch of the motor installation slot 104 and fixed by glue.

[0052] Based on the above embodiment, in a preferred embodiment, the sewage tank assembly includes a main control board 7, a drive motor 5 connected to a rotation sensor 8, and a gyroscope sensor. The rotation sensor 8 and the drive motor 5 are respectively in communication with the main control board 7. When the rotation sensor 8 senses that the tank body 1 is in the first state, the main control board 7 controls the drive motor 5 to rotate the hanging plate 3 to the second position. When the rotation sensor 8 senses that the tank body 1 is in the second state, the main control board 7 controls the drive motor 5 to rotate the hanging plate 3 to the first position. The drive motor 5 is provided with a torque sensor for detecting the rotation angle of the drive motor 5, so that the drive motor 5 can drive the hanging plate 3 to rotate between the first and second positions. Specifically, because the rotation sensor 8 is mounted on the drive motor 5, and the drive motor 5 is fixedly connected to the tank body 1, when the state of the tank body 1 changes, the state of the drive motor 5 also changes. Therefore, the rotation sensor 8 can sense that the tank body 1 switches from the first state to the second state, or from the second state to the first state. By setting up a rotary sensor 8, the rotary sensor 8 and the drive motor 5 are respectively communicated with the main control board 7. When the rotary sensor 8 senses that the box body 1 is in the first state, the main control board 7 can control the drive motor 5 to drive the hanging plate 3 to rotate to the second position. When the rotary sensor 8 senses that the box body 1 is in the second state, the main control board 7 controls the drive motor 5 to drive the hanging plate 3 to rotate to the first position. Automatic control can be achieved without the need for additional user operation, which is more convenient for users to use.

[0053] Based on the above embodiment, in a preferred embodiment, a first conductive member 9 is provided on the housing 1, and the first conductive member 9 is connected to the drive motor 5 via a first conductive wire 10. The sewage tank assembly also includes a body 11, and the main control board 7 is disposed on the body 11. The body 11 is further provided with a second conductive member 12 connected to the main control board 7 via a second conductive wire, and the second conductive member 12 is in contact with the first conductive member 9. In this embodiment, by providing the first conductive member 9 and the second conductive member 12, the main control board 7 disposed on the body 11 supplies power to the drive motor 5 via the first conductive member 9 and the second conductive member 12. Therefore, there is no need to provide an additional power supply on the housing 1, and the structure is simpler and more compact.

[0054] Specifically in one embodiment, the first conductive member 9 and the second conductive member 12 are both conductive sheets. In other alternative embodiments, the first conductive member 9 and the second conductive member 12 may be in the form of blocks or strips.

[0055] Based on the above embodiment, in a preferred embodiment, the box body 1 is provided with a first fixing groove 105, and the first conductive member 9 is disposed in the first fixing groove 105. In this embodiment, the provision of the first fixing groove 105 facilitates the installation and fixation of the first conductive member 9.

[0056] Specifically, the first conductive member 9 is glued in the first fixing groove 105 .

[0057] On the basis of the above embodiment, in a preferred embodiment, the box body 1 is provided with a wire groove 106, and the first wire 10 is arranged in the wire groove 106. In this embodiment, the provision of the wire groove 106 facilitates the installation and fixation of the first wire 10.

[0058] Specifically, the first wire 10 is stuck in the wire groove 106 and waterproof glue is injected.

[0059] Based on the above embodiment, in a preferred embodiment, a second fixing groove 1101 is provided on the body 11, and the second conductive member 12 is disposed in the second fixing groove 1101. In this embodiment, the second fixing groove 1101 is provided to facilitate installation and fixation of the second conductive member 12.

[0060] Specifically, the second conductive member 12 is glued in the second fixing groove 1101 .
