Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and in particular to a sewage tank assembly of a cleaning device and a cleaning device having the same. Background Art

[0002] 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.

[0003] 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. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the floor scrubber in the prior art cannot achieve the 180-degree flat mopping function, thereby providing a sewage tank assembly of a cleaning device that can achieve the 180-degree flat mopping function and a cleaning device having the same.

[0005] To solve the above technical problems, the present invention provides a sewage tank assembly of a cleaning device, comprising: a box body, a first end of which has a sewage inlet, a second end of the box body being an air duct outlet, a fan being suitable for being arranged on the outer side of the second end of the box body, and the fan being able to allow sewage to enter the box body from the sewage inlet when working, and the box body having a first state of being placed upright and a second state of being placed horizontally; a hanging plate rotatably arranged in the box body, the hanging plate having a first position of blocking part of the passage between the sewage inlet and the air duct outlet, and a second position of clearing the passage between the sewage inlet and the air duct outlet, when the box body is in the first state, the hanging plate rotates to the second position under the action of gravity, and when the box body is in the second state, the hanging plate rotates to the first position under the action of gravity.

[0006] Optionally, when the box is in the first state of being placed upright, the first position is a position perpendicular to the height direction of the box, and the second position is a position parallel to the height direction of the box.

[0007] Optionally, when the hanging plate is in the first position, the cross section of the box body is divided into a first area and a second area at the hanging plate, the hanging plate closes the first area, and the second area enables fluid communication between the first end and the second end.

[0008] Optionally, when the box is in the second state where the box is placed horizontally, the channel between the sewage inlet and the air duct outlet includes a lower channel and an upper channel distributed radially along the box, the partial channel includes the lower channel, and the hanging plate is used to block the fluid accumulated in the lower channel.

[0009] Optionally, the hanging plate includes a plate body and a rotating shaft connected to the plate body, and the box body is provided with a hinge hole hinged to the rotating shaft.

[0010] Optionally, the hanging plate is provided with two coaxially arranged rotating shafts, and the box body is provided with two hinge holes corresponding to the two rotating shafts.

[0011] Optionally, a filter assembly is provided at the air duct outlet.

[0012] Optionally, the filter component is a sponge.

[0013] Optionally, a sewage inlet pipe is provided in the box body, and one end of the sewage inlet pipe constitutes the sewage inlet.

[0014] The present invention also provides a cleaning device comprising the sewage tank assembly.

[0015] The technical solution of the present invention has the following advantages:

[0016] The sewage tank assembly of the cleaning device provided by the present invention has a first upright position when the scrubber is in an upright position. The operation of the fan can create a negative pressure inside the tank, causing sewage to enter the tank through the sewage inlet. Since the tank is upright, the sewage does not flow upward onto the fan, but is stored inside the tank. Air is discharged outside the tank through the air duct outlet. When the scrubber is in a 180-degree flat mopping position, the tank is in a second horizontal position. At this time, the sewage in the tank may flow horizontally toward the air duct outlet and then onto the fan. Therefore, by providing a hanging plate, when the tank rotates from the first position to the second position, the hanging plate rotates relative to the tank to the first position under the action of its own gravity. 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

[0028] Example 1

[0029] 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.

[0030] 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.

[0031] To this end, this embodiment provides a sewage tank assembly for a cleaning device, wherein the cleaning device is preferably a floor scrubber.

[0032] In one embodiment, Figures 1 to 4 As shown, the sewage tank assembly includes a tank body 1 and a hanging plate 2.

[0033] 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 an air duct outlet 102. The outer side of the second end of the box body 1 is suitable for arranging a fan. When the fan is working, the sewage can enter the box body 1 from the sewage inlet 101. The box body 1 has a first state of being placed upright and a second state of being placed horizontally; the hanging plate 2 is rotatably arranged in the box body 1, and the hanging plate 2 has a first position of blocking part of the channel between the sewage inlet 101 and the air duct outlet 102, and a second position of making way for the channel between the sewage inlet 101 and the air duct outlet 102. When the box body 1 is in the first state, the hanging plate 2 rotates to the second position under the action of gravity. When the box body 1 is in the second state, the hanging plate 2 rotates to the first position under the action of gravity.

[0034] In this embodiment, when the scrubber is upright, the box body 1 is in a first state of vertical placement, and the operation of the fan 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 upward to the fan, and the sewage will be stored in the box body 1. The air will be discharged outside the box body 1 after passing through the air duct outlet 102; when the 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 into the box body 1. The wastewater flows horizontally toward the air duct outlet 102 and then onto the fan. Therefore, by providing the hanging plate 2, when the housing 1 rotates from the first state to the second state, the hanging plate 2 rotates relative to the housing 1 to the first position under the action of its own gravity. At this time, the hanging plate 2 blocks part of the passage between the sewage inlet 101 and the air duct outlet 102. However, the wastewater can still enter the housing 1 from the sewage inlet 101 under the action of the fan. At this time, the hanging plate 2 can block the wastewater from flowing toward the air duct outlet 102, thereby preventing the wastewater from rushing into the fan and damaging it. Therefore, the wastewater tank assembly can achieve a 180-degree flat drag function.

[0035] It should be noted that the hanging plate 2 rotates relative to the box body 1. In fact, the position of the hanging plate 2 may not change, and only the box body 1 rotates, thereby changing the relative position of the box body 1 and the hanging plate 2. By changing the relative position of the box body 1 and the hanging plate 2, the purpose of blocking part of the passage between the sewage inlet 101 and the air duct outlet 102 or making way for the passage between the sewage inlet 101 and the air duct outlet 102 is achieved.

[0036] 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 2 is in a vertical position and does not affect the flow of air within the housing 1, thereby creating sufficient negative pressure within the housing 1 to absorb the sewage from the cleaning device. When the housing 1 is in the second state, the hanging plate 2 remains in a vertical position due to its gravity, at which point the hanging plate 2 can block the sewage from flowing toward the fan. In other alternative embodiments, the first position forms a certain angle with the vertical direction, and the angle is less than 90° or greater than 90°, and the second position forms a certain angle with the vertical direction, and the angle is less than 90° or greater than 90°, that is, when the box body 1 is in the first state, the hanging board 2 is not in a vertical state, and when the box body 1 is in the second state, the hanging board 2 is also not in a vertical state. In this embodiment, a limiting portion is provided in the box body 1 to keep the hanging board 2 in its position, so that the hanging board 2 cannot reach a vertical state.

[0037] Based on the above embodiment, in a preferred embodiment, when the hanging plate 2 is in the first position, the cross-section of the housing 1 is divided at the hanging plate 2 into a first area and a second area 103. The hanging plate 2 seals the first area, while the second area 103 allows fluid communication between the first end and the second end. In this embodiment, when the floor scrubber is mopping 180 degrees flat, the hanging plate 2 only seals the first area, leaving the second area 103 unsealed. This does not affect the normal flow of air, thereby maintaining a negative pressure within the housing 1 to absorb wastewater from the cleaning device and ensuring that wastewater can enter the housing 1 through the wastewater inlet 101.

[0038] It should be noted that when the floor scrubber is mopping 180 degrees, the first area is located below the second area 103, and the sewage in the box 1 accumulates in the first area below, thereby preventing the sewage from flowing through the second area 103 to the air duct outlet 102 and then flowing to the fan.

[0039] Based on the above embodiment, in a preferred embodiment, when the housing 1 is in the second horizontal position, the channel between the sewage inlet 101 and the air duct outlet 102 includes a lower channel and an upper channel distributed radially along the housing, the partial channel includes the lower channel, and the hanging plate 2 is used to block fluid accumulated in the lower channel. In this embodiment, the hanging plate 2 is used to block the fluid accumulated in the lower channel from flowing toward the fan.

[0040] Based on the above embodiment, in a preferred embodiment, the hanging plate 2 includes a plate body 201 and a rotating shaft 202 connected to the plate body 201. The housing 1 is provided with a hinge hole 104 for hinged connection to the rotating shaft 202. In this embodiment, the hinge hole 104 positions and mounts the rotating shaft 202, ensuring that the hanging plate 2 can rotate freely. In an alternative embodiment, the rotating shaft 202 can be provided on the housing 1, and the hinge hole 104 can be provided on the hanging plate 2.

[0041] It should be noted that the hinge hole 104 and the rotating shaft 202 are clearance-fitted, thereby ensuring that the hanging plate 2 can rotate freely. At the same time, the damping force of the hinge hole 104 and the rotating shaft 202 is greater than the suction force of the fan, thereby reducing the phenomenon of the hanging plate 2 rotating due to the suction force of the fan.

[0042] Based on the above embodiment, in a preferred embodiment, the hanging plate 2 is provided with two coaxially arranged rotating shafts 202, and the box body 1 is provided with two hinge holes 104 corresponding to the two rotating shafts 202. In this embodiment, by providing two rotating shafts 202 and two hinge holes 104, the position of the hanging plate 2 can be ensured to be stable and will not deflect during rotation.

[0043] Based on the above embodiment, in a preferred embodiment, a filter assembly is provided at the air duct outlet 102. In this embodiment, by providing the filter assembly at the air duct outlet 102, the filter assembly can filter dirt and prevent the dirt from flowing out of the box body 1. The fan is located on a side of the filter assembly away from the sewage inlet 101.

[0044] Based on the above embodiment, in a preferred embodiment, the filter component is a sponge 3. In this embodiment, the sponge 3 component can filter dirt and prevent the dirt from flowing out of the box 1. At the same time, the sponge 3 component also has water absorption properties, and absorbs moisture in the air when the air flows through the air duct outlet 102.

[0045] Based on the above embodiment, in a preferred embodiment, a sewage inlet pipe 105 is provided within the housing 1, one end of which constitutes a sewage inlet. In this embodiment, sewage enters the housing 1 through the sewage inlet pipe 105 under the action of vacuum suction, then flows around the second end of the sewage inlet pipe 105 and is stored in the sewage tank.

[0046] like Figures 2 to 4 As shown, the hanging plate 2 is arranged near the other end of the sewage inlet pipe 105.

The structure of the floor scrubber other than the sewage tank assembly is not the focus of this embodiment and will not be described in detail. The working principle of the floor scrubber is also well known to those skilled in the art and will not be described in detail in this embodiment.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
