Description

Technical Field

[0001] This utility model belongs to the technical field of water-saving toilets, and relates to a toilet back panel opening and closing device. Background Technology

[0002] As a core facility in modern bathroom spaces, the hygiene performance of toilets directly impacts user experience. Traditional toilets typically consist of a body, seat, and lid, among which the seat is prone to bacterial growth due to frequent contact with the human body.

[0003] Currently, most mainstream toilets on the market consist of a main body, a seat, and a lid. Cleaning them largely relies on manual operation. Users need to periodically remove the seat and clean its surface and back by brushing and spraying disinfectant. Manual cleaning suffers from significant individual differences: the amount of cleaning agent used, the intensity of rinsing, and the wiping time cannot be standardized. Residual chemicals may irritate the skin, while incomplete rinsing can cause disinfectant to mix with dirt, forming an adhesive layer that becomes a breeding ground for bacteria.

[0004] In addition, in public places with high traffic, toilet seats are more prone to contamination, and manual cleaning is difficult to keep up in time. Therefore, most users either avoid touching the toilet seat or wipe it repeatedly when using public toilets.

[0005] Therefore, it is necessary to design an automated cleaning device that can clean the toilet seat ring promptly after each use. Such an automated cleaning device must have a properly opening and closing cleaning space to prevent water from splashing onto the toilet body during cleaning. How to design such a cleaning space is a key technical problem that this invention urgently needs to solve. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the background art by proposing a toilet back panel opening and closing device.

[0007] To achieve the technical objective, the technical solution adopted by this utility model is as follows:

[0008] The toilet back panel opening and closing device includes a toilet body, an openable toilet seat ring on the toilet body, a cleaning chamber at the rear of the toilet body, a cleaning space inside the cleaning chamber, an opening at the front of the cleaning chamber for the toilet seat ring to pass through, and a movable back panel on the cleaning chamber. The back panel moves to open and close the opening of the chamber. When the toilet seat ring is lifted, it can move into the cleaning space through the opening of the chamber.

[0009] To optimize the aforementioned technical solution, the specific measures also include:

[0010] The cleaning box described above is a rectangular box. Slide rails are provided on both sides of the front face of the cleaning box. The back panel is movably installed on the slide rails. When the back panel moves to the upper end of the slide rail, the opening of the box is open. When the back panel moves to the lower end of the slide rail, the back panel covers the opening of the box and closes the opening.

[0011] The back panel is equipped with rollers on both the left and right sides. The rollers are locked in the slide rails and can roll up and down along the slide rails. The back panel moves up and down by rolling the rollers.

[0012] The cleaning tank described above has rigid supports on each side and transparent material on each surface.

[0013] The aforementioned cleaning chamber is equipped with a backplate drive unit, which includes a backplate motor, a first drive wheel, a belt, a second drive wheel, and a fixed connector. The backplate motor is fixed to the upper end of the cleaning chamber. The first and second drive wheels are rotatably mounted on the inside of the cleaning chamber, one above the other. The belt is wound around the first and second drive wheels. The backplate motor is connected to the first drive wheel, and the belt is fixedly connected to the backplate through the fixed connector.

[0014] The aforementioned belt is also equipped with a sensor, and two position sensors, one up and one down, are installed inside the cleaning chamber. The position sensors are connected to the back plate motor. When the back plate moves to the upper or lower end of its travel, the sensor moves to the corresponding position sensor. When the position sensor detects the sensor, it controls the back plate motor to stop operating.

[0015] The bottom of the aforementioned back panel is equipped with an anti-pinch pad.

[0016] The bottom of the aforementioned cleaning tank is equipped with a tank guide channel, and a drain hole is provided in the tank guide channel, which is connected to the sewer.

[0017] The bottom of the side of the back panel facing the cleaning space is provided with a back panel guide channel. The back panel guide channel is arranged horizontally and the opening of the back panel guide channel is above the guide channel of the box body.

[0018] The toilet body has a seat ring motor fixed at the rear end. The seat ring motor is connected to the toilet seat ring and can drive the toilet seat ring to open and close.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model designs a cleaning chamber with a movable back panel. When the back panel is raised, the toilet seat can be lifted into the cleaning chamber. When the back panel is lowered, the toilet seat is separated from the toilet body. This allows the toilet seat to be cleaned inside the cleaning chamber without water splashing onto the toilet body, effectively preventing cross-contamination.

[0021] This utility model has an anti-pinch soft pad at the bottom of the back panel. When the back panel is lowered, if someone accidentally places their hand at the opening of the box and the back panel pinches their hand, the anti-pinch soft pad can deform to prevent the back panel from pinching the person's hand, which makes the structure of this utility model safer and more reliable.

[0022] This invention features drainage channels at the bottom of the cleaning chamber and the bottom of the back panel, which can smoothly drain the wastewater from the cleaning chamber and prevent wastewater from accumulating in the cleaning chamber. Attached Figure Description

[0029] like Figure 1-3 As shown, the toilet back panel opening and closing device of this utility model mainly includes a cleaning tank 3, a back panel 4, and a back panel driving unit 5. The cleaning tank 3 is a rectangular box, with each side constructed of stainless steel supports and each surface made of transparent plastic. The purpose of using transparent plastic is to make the cleaning process inside the cleaning tank 3 visible. The interior of the cleaning tank 3 is the cleaning space.

[0030] The toilet body 1 is equipped with an openable toilet seat ring 2, which is driven by a seat ring motor 21. The cleaning chamber 3 is located behind the toilet body 1, and the two are rigidly connected by bolts. The main structure of the cleaning chamber 3 includes a chamber opening 31, slide rails 32, and a chamber guide channel 33. The chamber opening 31 is located at the lower part of the front side of the cleaning chamber 3, and its width is slightly larger than the width of the toilet seat ring 2. When the toilet seat ring is tilted upwards at more than 90°, its end can be completely screwed into the cleaning space through the chamber opening 31. Stainless steel slide rails 32 are welded to both sides of the front face of the cleaning chamber 3, and nylon rollers 43 are installed on both sides of the back plate 4, with the rollers 43 embedded in the grooves of the slide rails 32. When the back plate 4 moves upwards along the slide rails 32 to a high position, the chamber opening 31 is fully open, such as... Figure 1 As shown; when the back plate 4 moves down to the bottom of the slide rail, its edge is sealed and fitted with the periphery of the box opening 31.

[0031] The backplate drive unit 5 is installed at the top inside the cleaning chamber 3. The output shaft of the backplate motor 51 is connected to the first transmission wheel 52, and the second transmission wheel 54 is fixed in the middle of the chamber. The belt 53 wraps around the two wheels. The backplate 4 is fixed to the outside of the belt 53 by an aluminum alloy fixing connector 55. A magnet is attached to the inside of the belt 53 as a sensing element 56, and two Hall effect position sensors 57 are installed on the inner wall of the chamber. When the backplate 4 moves to the top of its travel, the magnet triggers the upper position sensor 57, causing the backplate motor 51 to be de-energized; the same applies to the lower position.

[0032] The cleaning tank frame 3 is welded from stainless steel square tubes. The bottom of the tank is provided with an inclined tank guide channel 33, and a drain hole 34 is opened at the bottom of the channel and connected to the sewer.

[0034] The bottom edge of the back panel 4 is covered with a silicone anti-pinch soft pad 41.

[0035] The usage process of this utility model is as follows:

[0036] When the toilet seat 2 needs to be moved into the cleaning tank 3 for washing, the back panel motor 51 operates, raising the back panel 4 to a high position. Then, the seat ring motor 21 operates, lifting the toilet seat 2 so that the entire toilet seat 2 enters the cleaning tank 3. Then, the back panel motor 51 operates, lowering the back panel 4. The cleaning equipment inside the cleaning tank 3 washes the toilet seat 2, and the washing water is discharged from the drain hole 34 through the back panel guide channel 42 and the tank guide channel 33. The blower inside the cleaning tank 3 dries the toilet seat 2. After completion, the back panel motor 51 operates, raising the back panel 4 to a high position. The seat ring motor 21 operates, returning the toilet seat 2 to its original position. The back panel motor 51 then lowers the back panel 4, completing one cleaning cycle.
