Description

Technical Field

[0001] This utility model relates to a toilet seat that facilitates the replacement of the film roll. Background Technology

[0002] In current market automatic membrane replacement devices, the cover is usually closed by a snap-on or side-mounted mechanism.

[0003] When using a snap-on film replacement system, numerous inconveniences and problems often arise during actual operation. For example, forcibly opening the hatch can easily cause the snap to break, thus affecting the hatch's normal closing function. Moreover, even if the snap is not broken, accurately reinstalling it in the correct position is quite difficult, which is known as alignment trouble. If the snap is not accurately reinstalled in its original machine state, it will cause the machine to malfunction, affecting the normal operation of the entire automatic film replacement device, reducing work efficiency, and increasing maintenance costs and time. Utility Model Content

[0004] This invention provides a toilet seat with an easy-to-replace membrane roll, which can effectively solve the above-mentioned problems.

[0005] This utility model is implemented as follows:

[0006] A toilet seat with a replaceable film roll includes a rear housing and a cover that fits onto the rear housing. The rear housing has an output compartment for a rotating output roller and a recovery compartment for a rotating recovery roller. The front end of the rear housing has an extension hole for the film from the output roller to extend out and an insertion hole for the film to wrap around the periphery of the seat ring, extend in, and be wound by the recovery roller. Both sides of the cover have downwardly extending side plates. The top surface of the rear housing has stepped grooves for the side plates to fit into the shape. The groove walls on both sides of the front end of the rear housing have outwardly protruding locking balls. The inner side of the side plates has snap-fit ​​grooves for the locking balls to engage and limit the cover from disengaging from the rear housing. An iron block is located on the bottom rear side of the cover, and a magnet is located on the top rear end of the rear housing to magnetically engage with the iron block.

[0007] As a further improvement, the number of iron blocks on the hatch cover in this application is two, and the two iron blocks are installed alternately on the left and right sides of the rear bottom surface of the hatch cover, and the number of magnets is set in correspondence with the number of iron blocks.

[0008] As a further improvement, a fixing hole is provided on the iron block, and a fixing post is vertically fixed on the hatch cover, which is interference-fitted into the fixing hole. The cross-sectional diameter of the fixing post is larger than the diameter of the fixing hole.

[0009] As a further improvement, the groove wall at the lower end of the snap-fit ​​groove is a limiting part for preventing the locking ball from disengaging, and an entry groove is provided on the lower end face of the side plate, located directly below the limiting part, into which the locking ball slides.

[0010] As a further improvement, a demagnetizing groove is provided on the front wall of the snap-fit ​​groove; when the hatch is slid backward, the locking ball slides forward from the snap-fit ​​groove into the demagnetizing groove and presses against the groove walls on both sides of the demagnetizing groove. At this time, the iron block and the magnet are demagnetized due to the misalignment along the front-back direction.

[0011] The beneficial effects of this utility model are:

[0012] This application uses a locking ball buckle to connect to the card slot to fix the two side plates of the hatch to the front end of the rear shell seat. Then, the rear end of the hatch is locked to the top surface of the rear end of the rear shell seat by using an iron block and a magnet. Both the installation and disassembly processes are extremely convenient, and it has the advantages of simple structure and easy operation. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-6 As shown, a toilet seat that facilitates the replacement of film rolls includes a rear housing 10 and a cover 20 that fits onto the rear housing 10. The rear housing 10 has an output compartment 11 for the output roller 111 to be rotatably mounted and a recovery compartment 12 for the recovery roller 121 to be rotatably mounted. The front end of the rear housing 10 has an extension hole 14 for the film from the output roller 111 to extend out and an insertion hole 15 for the film to cover the circumference of the seat ring 60, extend into it, and be wound by the recovery roller 121. The cover 20 has covers on both sides. There is a downward extending side plate 21. The top surface of the rear shell 10 is provided with a stepped groove 13 for the side plate 21 to fit into the shape. The stepped groove 13 is located on both sides of the groove wall at the front end of the rear shell 10, and a locking ball 131 is formed on the groove wall. The inner side of the side plate 21 is provided with a snap-fit ​​groove 212 for the locking ball 131 to fasten and limit the hatch cover 20 from disengaging from the rear shell 10. There is an iron block 30 on the bottom rear side of the hatch cover 20, and a magnet 40 is provided on the top rear end of the rear shell 10 to magnetically engage with the iron block 30.

[0024] The structure of each component of this utility model will be described below.

[0025] like Figure 3 and Figure 4As shown, in this application, the number of iron blocks 30 on the hatch 20 is two, and the two iron blocks 30 are installed on the left and right sides of the rear bottom surface of the hatch 20 at intervals. In other embodiments, for the sake of fixed strength, the number of iron blocks 30 can also be set to three, four or even more, and the number of magnets 40 needs to be set to correspond to the number of iron blocks 30.

[0026] like Figure 3 and Figure 4 As shown, a fixing hole 31 is provided on the iron block 30, and a fixing post 23 is vertically fixed on the hatch 20, which is interference-fitted in the fixing hole 31. The cross-sectional diameter of the fixing post 23 is larger than the diameter of the fixing hole 31. A protruding post with a mounting hole 161 is provided on the top surface of the rear shell seat 10. The magnet 40 is pressed into the mounting hole 161 and is positioned opposite to the iron block 30 on the hatch 20. It should be noted that, for the sake of installation stability, the iron block 30 in this application is a magnetic sheet, and the magnet 40 is a rubidium magnet 40.

[0027] like Figure 5 and Figure 6 As shown, the lower wall of the locking groove 212 is a limiting part 2121 used to prevent the locking ball 131 from disengaging. The lower end face of the side plate 21 has an entry groove 211 located directly below the limiting part 2121 and allowing the locking ball 131 to slide in. This design allows the locking ball 131 to enter directly below the locking groove 212 when it slides into the side plate 21. The entry groove 211 also reduces the thickness of the limiting part 2121, making it easier for the locking ball 131 to engage with the locking groove 212. It should be noted that the hatch 20 is a plastic product with elasticity. Therefore, during the process of the locking ball 131 engaging with the locking groove 212, the limiting part 2121 can elastically move the locking ball 131 to make way.

[0028] like Figure 3 and Figure 6 As shown, a demagnetizing groove 213 is provided on the front wall of the snap-fit ​​groove 212. When the hatch cover 20 is slid backward, the locking ball 131 slides forward from the snap-fit ​​groove 212 into the demagnetizing groove 213 and forms contact with the groove walls on both sides of the demagnetizing groove 213. At this time, the iron block 30 and the magnet 40 are demagnetized due to the misalignment along the front-back direction. At this time, the hatch cover 20 can be lifted upward to expose the output roller 111 and the recovery roller 121 on the rear shell 10. It should be noted that the locking ball 131 will not slide relative to the snap-fit ​​groove 212 when no external force is applied.

[0029] The following is combined Figures 1-6 This paper details the working principle of this utility model and explains how to use the utility model to replace the output roller 111 and the recovery roller 121.

[0030] When replacing the output roller 111 and the recovery roller 121, slide the cover 20 backward. The locking ball 131 slides forward from the snap-fit ​​groove 212 into the demagnetizing groove 213 and forms contact with the two side walls of the demagnetizing groove 213. At the same time, the iron block 30 and the magnet 40 are misaligned and demagnetized. Apply upward force to lift the cover 20, and the output roller 111 and the recovery roller 121 in the rear housing 10 can be replaced. After the replacement is completed, align the locking ball 131 into the groove 211 and press down the cover 20 so that the locking ball 131 crosses the limiting part 2121 and snaps into the snap-fit ​​groove 212. The iron block 30 and the magnet 40 are magnetically attracted and fixed together, thus completing the quick replacement of the output roller 111 and the input roller.

[0031] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various modifications or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention, as defined by the claims.
