[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as limiting the present invention's toilet seat liner spreading and recycling system.

[0029] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0030] According to an overall technical concept of the present invention, such as Figure 9 As shown, a toilet seat film spreading and recycling system is provided, including a main body 1, a toilet seat 2, a film, and a rewinder 3. The film is a single-layer long strip of plastic film with a certain longitudinal tensile force. The width of the film is slightly larger than the width of the toilet seat 2. The film has several dotted dividing lines 405 printed along its width direction, which divide the film into several pieces of seat film 4. In practical applications, a certain number of seat film 4 can be rolled onto a rigid tube core 1041 as needed to form a seat film roll 104. A notch 1042 is provided at one end of the rigid tube core for easy installation.

[0031] like Figures 2-3As shown, in one embodiment, each seat cushion film 4 has a hole 401 in the middle that fits the toilet seat, and a protruding isolation tongue 402 at the front end of the hole 401 to separate the protruding part of the human body from the edge of the toilet seat 2, forming a protective barrier. Each seat cushion film 4 is equipped with a light-controlled barcode 404, which contains a number that gradually increases from 0 to determine the amount of seat cushion film 4 in stock. A serrated cutting line 403 is pre-pressed at the longitudinal center of the seat cushion film 4, so that the seat cushion film 4 can be easily divided into two halves through the serrated cutting line 403 during recycling, improving recycling efficiency.

[0032] like Figures 4-5 As shown, in this embodiment, the main housing 1 serves as a storage box for the pad film roll 104, and includes a first housing 101, a first housing cover 102, a film pressing rod 105, a light control box 106, a rotating shaft 108, and a handwheel 109. Pulling the handwheel 109 out of the rotating shaft 108 allows the pad film roll 104 to be placed on the rotating shaft 108. Both ends of the rotating shaft 108 are provided with protruding pins that match the notches 1042. The protruding pins and notches 1042 are engaged to fix the pad film roll 104 on the rotating shaft 108. Then, the handwheel 109 is sleeved onto the rotating shaft 108, and rotating the handwheel 109 allows for adjustment of the pad film roll 104. The light control box 106 is installed inside the first housing 101. When laying the seat cushion film 4, the light control box 106 scans the light control barcode 404 to determine whether the seat cushion film 4 is laid in place and to read and record the information of the light control barcode 404. A pressure rod 105 is provided between the seat film roll 104 and the light control box 106 to keep the seat film 4 in contact with the probe of the light control box 106 at all times, so as to ensure the sensitivity of the probe of the light control box 106. A first guide wheel 107 is also provided in the first housing 101 to facilitate the transfer of the used seat film 4 to the rewinder 3 for recycling. On both sides of the front end of the first housing 101, there are seat pin holes 103 for connecting with the toilet seat 2. They are hinged to the toilet seat 2 by pins, so that the toilet seat 2 can be laid flat or flipped upright with these as the pivot point.

[0033] like Figures 6-7 As shown, in a specific embodiment, the toilet seat 2 is divided into an upper panel 201 and a lower base plate, with a toilet hole 202 in the middle. The upper panel 201 is a smooth panel that comes into contact with the human body, and the upper panel 201 and the lower base plate are separated by a certain distance to form a membrane channel 210. The lower base plate is further divided into a middle base plate 208 and two side base plates 209. The middle base plate 208 is fused to the upper panel 201 at the front fish mouth portion 204, the rear fish tail portion 205, and the inner ring edge portion 206, respectively. The two side base plates 209 are fused to the upper panel 201 at the side edge portion 207. The middle base plate 208 and the two side base plates 209 are separated by a certain distance to form two membrane grooves 211.

[0034] like ​As shown, in another specific embodiment, the winder 3 is composed of a second box body 301, a second box cover 302, a winding disc 303, a winding column 304, an axle seat 305, a central axle 306, a cover disc 307, a pressing disc wheel 308, a winding motor 309, a pulling motor 310, a fixed wheel 311 and an adjusting wheel 312. The central axle 306 is fixed in the central part of the second box body 301 through the axle seat 305, and the winding disc 303 is sleeved into the central axle 306 and can rotate freely. The winding disc 303 can be subdivided into a disc body and a column body. The outer circumference of the disc body is provided with a gear disc, which is engaged with the driving gear of the output end of the winding motor 309. The main body is a conical body, and a notch is left on one side of the conical body. The winding column 304 is installed at the notch, and the connection between the cushion film 4 and the winding disc 303 can be quickly realized through the winding column 304 (when in use, the end of the cushion film 4 is aligned and wound on the column body for two or three turns). The connecting surface between the column body and the cover disc 307 is a spline shaft, and the spline sleeve of the cover disc 307 is sleeved into the spline shaft, so that the cover disc 307 and the winding disc 303 can rotate synchronously. A cavity is left between the cover disc 307 and the winding disc 303 to place the cushion film 4. The pressing disc wheel 308 is provided outside the cover disc 307 to limit the outward retreat of the cover disc 307. The pressing disc wheel 308 is fixedly connected with the central axle 306 through screws. After being tightened, the pressing disc wheel 308 can not only prevent the winding disc 303 from moving, but also does not affect the automatic rotation of the winding disc 303. The pulling motor 310 is in transmission connection with a transmission wheel, and the adjusting wheel 312 is arranged above the transmission wheel. The adjusting wheel 312 includes a supporting part and a rotating wheel. The supporting part is hinged to the inside of the second box body 301, and the other end pin shaft of the supporting part is in rotary connection with the rotating wheel, so that the adjusting wheel 312 is pressed on the surface of the fixed wheel 311. The pressure degree can be adjusted by adjusting the length of the supporting part, and the contact can be separated by adjusting the relative angle of the supporting part, which is convenient for placing the cushion film 4 between the adjusting wheel 312 and the fixed wheel 311 during initial installation.

[0035] Through the above arrangement, in actual application, the pulling motor 310 drives the fixed wheel 311 to drive the adjusting wheel 312 to rotate synchronously, so as to pull the cushion film 4 to move. The cushion film 4 outside the second box body 301 is pulled into the inside of the second box body 301 through the cushion film inlet 313. At this time, the winding motor 309 drives the winding disc 303 to rotate, and the cushion film 4 pulled into the second box body 301 is wound on the main body of the winding disc 303.

[0036] Preferably, in the embodiment, the second box body 301 can be arranged directly above the main box body 1, or can be arranged on both sides of the toilet body 5, or can be arranged on the wall body without being limited to a specific implementation manner.

[0037] In a particular embodiment, the second box 301 is internally provided with a control box, which is equipped with a computer chip for controlling the system process, and an operation panel is arranged on the control box, and a start button and an information display screen are arranged on the operation panel.

[0038] Before the system is normally operated, the initial installation of the cushion film 4 should be completed, and the initial installation of the system includes the following steps:

[0039] S1, the cushion film roll 104 is fixed between the rotating shaft 108 and the hand wheel 109, the cushion film 4 is pulled out from under the film pressing rod 105, and covers the light control box 106 and the toilet seat 2;

[0040] S2, the cushion film 4 is segmented into two halves along the sawtooth segmentation line 403, and after the appropriate length is segmented, the two halves of the cushion film 4 are placed into the cushion film passage 210 through the film installation groove 211 at the bottom of the toilet seat 2, and the cushion film 4 is passed through the cushion film passage 210, so that the cushion film 4 is in the state of embracing the upper panel 201 (i.e. the unused cushion film 4 covers the upper panel 201, and the used cushion film 4 is at the front end of the toilet, after being folded back by 180°, it is passed through the cushion film passage 210, and the upper panel 201 is clamped therebetween);

[0041] S3, the cushion film 4 coming out of the cushion film passage 210 is passed through the film port 110 of the main box 1 and returned to the main box 1;

[0042] S4, the cushion film 4 is passed out of the main box 1 according to the guide direction of the first guide wheel 107, and then the cushion film 4 is passed into the second box 301 according to the guide direction of the second guide wheel (not shown in the figure);

[0043] S5, the cushion film 4 is pressed between the fixed wheel 311 and the adjusting wheel 312, the end of the cushion film 4 is wound on the winding column 304 on the winding disc 303, the cover disc 307 is covered, and the pressing disc wheel 308 is screwed, and thus the initial installation is completed.

[0044] When using the toilet seat with the system, the user only needs to press the start button, and the seat cushion film 4 covering the entire toilet seat 2 can be quickly replaced under the user's visual inspection. The system operation process is as follows: after pressing the start button, the pulling motor 310 in the winder 3 starts to work, the pulling motor 310 drives the fixed wheel 311 to rotate, the fixed wheel 311 drives the adjusting wheel 312 to rotate, the rotation of the two wheels strongly pulls the seat cushion film 4 pressed between the two wheels, the pulling force moves the entire seat cushion film 4, the used seat cushion film 4 covering the panel of the toilet seat 2 is pulled into the seat cushion film channel 210 of the toilet seat 2, the entire seat cushion film 4 in the seat cushion film channel 210 cavity is separated into two halves along the pre-pressed sawtooth separation line 403 on the seat cushion film 4 when the fish mouth part with the shunt function is encountered, and moves from the seat cushion film channel 210 on both sides of the toilet seat 2 and enters the winder 3 under the guidance of the first guide wheel 107. While the old seat cushion film 4 is recycled, the new seat cushion film 4 is also pulled out from the main box 1, the old film is replaced, and the light control bar code 404 provided on the newly pulled out seat cushion film 4 passes through the probe of the light control box 106, the control system sends a stop signal, the pulling motor 310 of the winder 3 stops working, and the seat cushion film 4 stops moving. At this time, the new seat cushion film 4 completely covers the toilet seat 2 and is in a standby state, and the display screen on the control box displays the information content provided by the light control bar code 404, such as the number of used or remaining seat cushion films. When the remaining amount is about to run out, a voice prompt is sent. At the same time when the pulling motor 310 stops working, the winding motor 309 starts to work and drives the winding disc 303 to rotate, so that the seat cushion film 4 pulled into the second box 301 is wound in the winding disc 303. After winding is completed, the set winding disc 303 winding force cannot pull the seat cushion film 4 pressed between the pulling wheels any more, at which time the winding motor 309 stops working. After the seat cushion film 4 in the seat cushion film winding drum 104 is used up and the control system recycles all the seat cushion films 4, the control system is in a dormant state and cannot be started until the seat cushion film winding drum 104 is replaced. The replacement work only needs to unscrew the pressure disc wheel 308 in the winder 3, remove the cover disc 307, and then take out the old seat cushion film 4 wound on the winding disc 303 column. Since the disc column is a conical body with a tapered tip outward, it is very easy to take out. The old seat cushion film 4 taken out is a compact disc body and can be recycled as a renewable raw material. After completing the taking-out work, the replacement work is operated according to the initial installation work process, and after the replacement is completed, the system returns to the normal use state and the new wheel starts to work.

[0045] The present application can be used in household toilet and public toilet, the difference is the number of seat cushion film 4 set in each roll of the film roll 104. In public places with large flow of people (such as trains, shopping malls, schools, service areas, etc.), the public toilet is used, in order to avoid the film roll 104 frequent replacement, the large capacity film roll 104 can be used, the volume of the main box 1 and the winder 3 is increased accordingly. Or the main box 1 and the winder 3 are separated from the toilet body 5 to use the super large capacity film roll 104, and the labor of the manager is reduced.

[0046] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present application, and it should be understood that the above description is only a specific embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
