[0002] Existing toilets with automatic seat cover replacement all use a plastic film sleeve fitted onto the toilet seat as a seat cover, and the film sleeve is replaced by rotating a shaft.

[0003] However, toilet seat covers are usually made of transparent plastic film, and it is difficult to distinguish between a used cover and a new cover in terms of appearance. This makes it impossible for users to determine whether the cover has been used, so they have to change the cover every time they use the toilet, resulting in waste of the cover. Utility Model Content

[0004] This utility model provides a toilet seat device and a toilet, which makes it easy for users to identify whether the membrane cover has been used, thus avoiding the need to replace unused membrane covers and reducing waste.

[0015] In one exemplary embodiment, the color-changing substance is color-changing ink.

[0016] In one exemplary embodiment, the seat ring is a room temperature seat ring, and the color-changing ink is a thermochromic ink or a pressure-sensitive color-changing ink; or, the seat ring is an electrically heated seat ring, and the color-changing ink is a pressure-sensitive color-changing ink.

[0017] In an exemplary embodiment, the membrane sleeve replacement module includes: a membrane sleeve reel rotatably connected to the base and configured to fit unused membrane sleeves; a recycling reel configured to fit used membrane sleeves; and a drive unit connected to the recycling reel and configured to drive the recycling reel to rotate, thereby recycling the used membrane sleeves and causing the membrane sleeve reel to rotate so that unused membrane sleeves are fitted onto the seat ring.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0023] like Figure 1 As shown in the figure, this application provides a toilet seat device, including: a base 1, a seat ring 2, a diaphragm replacement module 3, and a prompting module 4.

[0024] The base 1 can be installed on the toilet seat 5 to connect the toilet seat device to the seat 5. The base 1 can be equipped with a washing module (to realize functions such as posterior washing and feminine washing) and a drying module (to realize the drying function).

[0025] The seat ring 2 is rotatably connected to the base 1 so that the seat ring 2 can be closed on the toilet seat 5 or lifted off the toilet seat 5, thereby allowing the seat ring 2 to adapt to different user usage methods.

[0026] The membrane sleeve replacement module 3 is installed on the base 1 and is configured to replace the membrane sleeve (not shown in the figure) mounted on the seat ring 2, making it convenient for users to replace used membrane sleeves. The membrane sleeve can be, but is not limited to, a transparent material; for example, it can also be made of a semi-transparent material. The material of the membrane sleeve can be, but is not limited to, plastic.

[0027] like Figure 2 As shown, the prompt module 4 is configured to apply a color-changing substance to the membrane sleeve. The color-changing substance displays different colors when the membrane sleeve is in use and when it is not in use, so that the use and unuse states of the membrane sleeve can be identified.

[0028] like Figure 1 and Figure 2As shown, compared to conventional designs, the embodiments of this application add a prompting module 4. This module applies a color-changing substance to the membrane sleeve, which displays different colors depending on whether the sleeve is in use or not. This allows the user to identify whether the membrane sleeve is in use or not based on the displayed color. Thus, when the user identifies the membrane sleeve as being in use, they can replace the sleeve mounted on the seat ring 2 using the membrane sleeve replacement module 3. When the user identifies the membrane sleeve as being in use, there is no need to replace it, thus avoiding the situation where the user is unsure whether the membrane sleeve has been used and replaces it again, resulting in the replacement of an unused membrane sleeve and reducing waste.

[0029] In one exemplary embodiment, such as Figure 2 As shown, the prompt module 4 includes a container 41 and an applicator 42. The container 41 contains a color-changing substance (not shown in the figure), and the container 41 is provided with a second clearance opening 411. The applicator 42 can obtain the color-changing substance in the container 41 through the second clearance opening 411 and contact the film sleeve to apply the color-changing substance to the film sleeve.

[0030] The container 41 can be rectangular, but is not limited to a cuboid shape; it can also be a cube, elliptical cylinder, or cylinder. The container 41 can hold a certain amount of color-changing substance, which helps extend the usage time of the indicator module and thus extends its replacement cycle. The applicator 42 can acquire the color-changing substance from the container 41 and apply it to the membrane sleeve, allowing the user to identify whether the membrane sleeve has been used (i.e., in use or unused) based on the color of the applied substance.

[0031] In one exemplary embodiment, such as Figure 2 As shown, the applicator 42 is a roller 422, which is rotatably connected to the receiving box 41.

[0032] Since the frictional force of rolling friction is generally much smaller than that of sliding friction, the coating part 42 adopts a rolling part 422, which helps to reduce the resistance applied by the coating part 42 to the film sleeve and facilitates the smooth and quick replacement of the film sleeve.

[0033] In other embodiments, the applicator 42 can also be a fixing member. For example, the fixing member has the function of absorbing the color-changing substance (such as a sponge-like material), the fixing member is fixedly connected to the receiving box 41, the lower end of the fixing member obtains the color-changing substance from the receiving box 41 and stores it in the fixing member, the upper end of the fixing member contacts the film sleeve, and applies the color-changing substance stored in the fixing member onto the film sleeve.

[0034] In one exemplary embodiment, such as Figure 2As shown, the seat ring 2 has a receiving cavity 22, the receiving box 41 is installed in the receiving cavity 22, the seat ring 2 also has a first clearance opening 23 communicating with the receiving cavity 22, and the applicator 42 passes through the first clearance opening 23 to contact the film sleeve.

[0035] The receiving box 41 is installed inside the seat ring 2 via a receiving cavity 22. This design makes efficient use of the space within the seat ring 2 to conceal the receiving box 41. This prevents the receiving box 41 from protruding from the seat ring 2 and scratching the diaphragm or the user, and also avoids the receiving box 41 occupying space within the base 1 and affecting the layout of other structures within the base 1. The structure is simple, easy to install, highly versatile, and compatible with existing toilets that have an automatic seat ring replacement function. The seat ring 2 has a first clearance opening 23 communicating with the receiving cavity 22 to ensure that the applicator 42 can contact the diaphragm and apply the color-changing substance to it. Furthermore, this design ensures that the applicator 42 can only apply the color-changing substance to the side of the diaphragm away from the user, preventing the color-changing substance from contacting the user and staining their skin, thus protecting the user's personal hygiene.

[0036] The shape of the first clearance opening 23 may be, but is not limited to, U-shaped, rectangular, circular or other shapes.

[0037] In one embodiment, such as Figure 3 As shown, the receiving box 41 is provided with two connecting parts 414 located on both sides of the first clearance opening 23 and arranged opposite to each other. The main body of the rolling element 422 is located between the two connecting parts 414, and the rolling element 422 is rotatably connected to the connecting parts 414, so that the rolling element 422 rotates smoothly.

[0038] In one example, such as Figure 3 and Figure 4 As shown, the rolling element 422 is configured as a roller, and two connecting shafts 421 are provided on both sides of the roller. The two connecting parts 414 are respectively provided with shaft holes 4141 corresponding to the connecting shafts 421. The roller and the connecting parts 414 are rotatably connected through the cooperation of the connecting shafts 421 and the shaft holes 4141.

[0039] In one exemplary embodiment, the seat ring 2 is provided with a loading and unloading opening communicating with the receiving cavity 22, the loading and unloading opening allowing the receiving box 41 to enter and exit the receiving cavity 22 for loading and unloading the receiving box 41.

[0040] This allows for the detachable assembly of the container 41 and the seat ring 2, making it convenient to replace the container 41 with a new one after the color-changing material is used up, or to replenish the color-changing material in the container 41 before reinstalling it onto the seat ring 2.

[0041] The location of the loading and unloading opening is unrestricted; for example, it can be located on the bottom wall, top wall, or side wall of the seat ring 2. In one example, such as... Figure 2As shown, the starting end of the seat ring 2 is open, forming a loading and unloading opening. In another example, the bottom wall of the seat ring 2 has a loading and unloading opening.

[0042] The receiving box 41 and the seat ring 2 can be connected by means of snaps (for example, pressing the receiving box 41 will insert it into the seat ring 2, and squeezing the snap will release the receiving box 41) or spring snaps (for example, pressing the receiving box 41 will insert it into the seat ring 2, and pressing the receiving box 41 again will pop it out), which helps to improve the positional stability of the receiving box 41 during use.

[0043] In one exemplary embodiment, such as Figure 2 As shown, the membrane sleeve replacement module 3 is configured to drive the membrane sleeve to move from the starting end of the seat ring 2 to the end of the seat ring 2, and the receiving cavity 22 is located at the starting end of the seat ring 2.

[0044] In this way, as the membrane sleeve replacement module 3 drives the membrane sleeve to move from the beginning to the end of the seat ring 2, the membrane sleeve will be coated with the color-changing substance as it slides or rolls against the coating material. When the newly coated membrane sleeve moves from the beginning to the end of the seat ring 2, it indicates that the membrane sleeve has been replaced. This avoids the situation where the membrane sleeve is partially replaced due to insufficient rotation during user operation, which helps to protect the user's personal hygiene.

[0045] Of course, the location of the receiving cavity 22 is not limited to the starting end of the seat ring 2, and can also be located at other positions of the seat ring 2. Alternatively, the receiving box 41 can also be located inside the base 1, as long as it is located on the movement path of the membrane sleeve, so that the color-changing substance can be applied to the membrane sleeve.

[0046] In one embodiment, the seat ring 2 can also be provided with multiple receiving cavities 22, each of which is provided with a receiving box 41, which can apply the color-changing substance to the membrane sleeve. The membrane sleeve is coated with more color-changing substance, and after the membrane sleeve is used, the user can more clearly identify the color of the color-changing substance, providing a better experience for users with visual impairments.

[0047] In one exemplary embodiment, such as Figure 2 As shown, the first clearance opening 23 is provided on the top wall of the seat ring 2 so that the coating member 42 can apply the color-changing substance to the lower surface of the film sleeve.

[0048] Since the width of the top wall of the seat ring 2 is generally significantly greater than the width of the side wall, the width of the film sleeve covering the top wall of the seat ring 2 is also significantly greater than the width covering the side wall of the seat ring 2. Therefore, setting the first clearance opening 23 on the top wall of the seat ring 2 can, on the one hand, reduce the requirement for the application width of the coating component 42, making it easier to appropriately increase the application width of the coating component 42 as needed to enhance the color rendering effect; on the other hand, the color-changing substance is applied to the lower surface of the film sleeve, located within the main range of the user's field of vision, making it easy for the user to see, thereby improving the prompting effect.

[0049] In other embodiments, the first clearance opening 23 can also be provided on the side wall of the seat ring 2, in which case the color-changing substance will be applied to the side surface of the film sleeve, which can also achieve the indication function.

[0050] In one exemplary embodiment, the color-changing substance is a liquid. For example... Figure 3 As shown, the prompt module 4 also includes an adsorption element 43, which is located inside the receiving box 41 to absorb the discoloration substance.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, the container 41 is provided with a second clearance opening 411, and the applicator 42 passes through the second clearance opening 411 and contacts the adsorption member 43 to obtain the color-changing substance.

[0052] By utilizing the adsorption properties of the adsorption element 43, the liquid color-changing substance can be concentrated near the applicator 42 and dispersed in that area. This ensures that even a small amount of color-changing substance in the container 41 can be effectively absorbed by the applicator 42, preventing excessive absorption and application of a thick layer of color-changing substance on the membrane sleeve, which could cause smudging and affect the appearance of the membrane sleeve. Therefore, the adsorption element 43 not only extends the service life of the indicator module but also helps prevent the membrane sleeve from appearing dirty due to the application of color-changing substance.

[0053] The absorbent 43 can be, but is not limited to, a sponge, such as fiber cloth, absorbent paper, cotton, polyurethane foam, etc.

[0054] The shape of the second clearance opening 411 can be, but is not limited to, rectangular. For example, the shape of the second clearance opening 411 can also be U-shaped or other irregular shapes.

[0055] In one exemplary embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the container 41 includes a container body 412 and a lid 413. The upper end of the container body 412 has an opening, and the discoloring substance is located inside the container body 412. The lid 413 is placed over the opening of the container body 412 and is configured to be able to open or close the opening.

[0056] This allows users to easily open the lid 413, which is located at the opening of the box body 412, and promptly add the color-changing substance into the box body 412.

[0057] In one exemplary embodiment, the color-changing substance is a color-changing ink.

[0058] Color-changing ink is a special type of ink that changes color according to temperature changes, light, or other external stimuli. The applicator 42 applies the color-changing ink to the membrane sleeve. The ink changes color in response to external stimuli, making it easy for the user to identify. When the color-changing ink changes color, it indicates that the ink on the membrane sleeve has been exposed to external stimuli (i.e., the membrane sleeve has been used), thus automatically reminding the user to replace the used membrane sleeve.

[0059] In some embodiments, the color-changing ink is a thermochromic ink or a pressure-sensitive color-changing ink.

[0060] Thermochromic ink is a special type of ink that changes color according to temperature. When a specific temperature threshold is reached, the ink undergoes a physical or chemical change. For example, when the temperature rises, the heat-sensitive components in the ink (such as microcapsules of liquid crystal or dye) undergo a physical phase change or chemical structural change when the temperature reaches a preset threshold (such as human body temperature, approximately 36℃-37℃), resulting in altered light absorption / reflection characteristics and thus color differences. Thermochromic ink can be water-based. Water-based thermochromic ink consists of the following components: resin (water-soluble resin, colloidal dispersion, emulsion polymer, etc.), water solvent (ammonia, alcohols), color-changing pigment (microcapsule thermochromic powder), additives (refer to solvent-based inks), and water.

[0061] Pressure-sensitive color-changing inks contain pressure-sensitive microcapsules encapsulating colorless dyes and a color-developing matrix. When subjected to pressure, the microcapsules are ruptured, allowing the dye to contact the matrix and undergo a color-developing reaction, thereby altering the light absorption, reflection, or scattering properties. The pressure threshold triggering the color change can be controlled by adjusting the capsule wall thickness or the material hardness.

[0062] Pressure-sensitive color-changing inks mainly consist of film-forming resins, solvent systems, and pressure-sensitive color developers. The film-forming resin, acting as the ink matrix, provides adhesion and film-forming properties. Commonly used resins include acrylic resins, polyurethane resins, or epoxy resins. Some formulations use polyvinyl butyral to enhance flexibility and weather resistance. The solvent system includes organic solvents (such as ethanol and butyl acetate) or aqueous solvents, used to adjust ink flow and drying speed. Aqueous formulations are more environmentally friendly but require the addition of anti-settling agents. Pressure-sensitive color developers include: organic fluorescent materials, such as anthracene derivatives and tetraphenylethylene compounds, which achieve pressure-responsive color changes through alterations in molecular packing structure; and liquid crystal materials, where the helical structure of the cholesteric liquid crystal layer changes under pressure, dynamically regulating the reflected wavelength.

[0063] In one embodiment, the seat ring 2 is a room temperature seat ring, and the color-changing ink is a thermochromic ink or a pressure-sensitive color-changing ink.

[0064] When seat ring 2 is a room temperature seat ring 2, it does not have a heating function and can use thermochromic ink. Thermochromic ink is transparent and colorless at room temperature. When a person sits on seat ring 2, the body transfers heat to the color-changing ink through the membrane. Since the body temperature is higher than the color-changing temperature value of the color-changing ink, the color-changing ink will turn colored, allowing the user to recognize the color change of the ink and realize that the membrane has been used. This can remind the user to replace the used membrane in time, avoiding the waste caused by the user replacing the unused membrane without being able to recognize whether the membrane has been used.

[0065] To avoid the influence of room temperature on thermochromic inks, the color-changing temperature value of thermochromic inks can be set to ≥35℃ (normally the indoor temperature will not be higher than this temperature).

[0066] When seat ring 2 is a room temperature seat ring 2, pressure-sensitive color-changing ink can also be used. Pressure-sensitive color-changing ink is transparent and colorless at room temperature. When a person sits on the room temperature seat ring 2, the person will press the pressure-sensitive color-changing ink applied to the membrane cover. Due to the pressure, the pressure-sensitive color-changing ink will change from colorless under normal conditions to colored, so that the user can recognize the color change of the color-changing ink and realize that the membrane cover has been used. This can remind the user to replace the used membrane cover in time, and avoid the user being unable to recognize whether the membrane cover has been used and replacing the unused membrane cover, which would be wasteful.

[0067] In one embodiment, the seat ring 2 is an electrically heated seat ring, and the color-changing ink is a pressure-sensitive color-changing ink.

[0068] When the seat ring 2 is electrically heated, it has a heating function. However, the heating of the seat ring 2 may cause the thermochromic ink to change color, interfering with the indication of the membrane sleeve's usage status. Therefore, pressure-sensitive ink can be used in this case. Pressure-sensitive ink is transparent and colorless at room temperature. When a person sits on the seat ring 2, the person will press the pressure-sensitive ink applied to the membrane sleeve. Due to the pressure, the pressure-sensitive ink will change from colorless under normal conditions to colored, allowing the user to recognize the color change and realize that the membrane sleeve has been used. This can remind the user to replace the used membrane sleeve in time, avoiding waste caused by the user replacing unused membrane sleeves without being able to identify whether the membrane sleeve has been used.

[0069] In one exemplary embodiment, such as Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the membrane sleeve replacement module 3 includes: a membrane sleeve reel 31, a recycling reel 32, and a drive unit (not shown in the figure). The membrane sleeve reel 31 is rotatably connected to the base 1 and is configured to hold unused membrane sleeves. The recycling reel 32 is configured to hold used membrane sleeves. The drive unit is connected to the recycling reel 32 and is configured to drive the recycling reel 32 to rotate, thereby recycling used membrane sleeves and causing the membrane sleeve reel 31 to rotate, so that unused membrane sleeves are fitted onto the seat ring 2.

[0070] like Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the film sleeve reel 31 is positioned corresponding to the starting end of the seat ring 2, and unused film sleeves are fitted onto the film sleeve reel 31. A recycling reel 32 is used to reel in used film sleeves. The recycling reel 32 can be installed on the base 1 and is positioned corresponding to the end of the seat ring 2. A drive unit is connected to the recycling reel 32, driving the recycling reel 32 to rotate, thus recycling used film sleeves. The movement of the film sleeves drives the film sleeve reel 31 to rotate, allowing unused film sleeves to be fitted onto the seat ring 2. In this way, when the user detects the color-changing substance applied to the film sleeve changing color, the drive unit rotates the recycling reel 32, allowing used film sleeves to be fitted onto the recycling reel 32. The recycling reel 32, through the film sleeves, drives the film sleeve reel 31 to rotate, allowing unused film sleeves to be fitted onto the seat ring 2, achieving automatic film sleeve replacement and improving the user experience.

[0071] In one embodiment, such as Figure 8As shown, both the membrane sleeve reel 31 and the recycling reel 32 are detachably connected to the base 1. This allows the user to easily remove the membrane sleeve reel 31 after all unused membrane sleeves have been used up and install new ones, or directly replace the reel 31 containing unused membrane sleeves. Similarly, when the recycling reel 32 can no longer hold more used membrane sleeves, the user can easily remove the used membrane sleeves from the recycling reel 32 or directly replace the recycling reel 32 with one that has not yet been used. Both the membrane sleeve reel 31 and the recycling reel 32 can be reused or used only once.

[0072] In one embodiment, such as Figure 8 As shown, the base 1 has a first connecting hole 11 on one side, into which the membrane sleeve reel 31 is inserted for limiting its position. The side of the base 1 facing the seat ring 2 has a first opening 12 corresponding to the starting end of the seat ring 2, allowing unused membrane sleeves to extend and fit around the outer circumference of the seat ring 2. The side of the base 1 away from the first connecting hole 11 has a third connecting hole (not shown), into which the recycling reel 32 is inserted for limiting its position. The side of the base 1 facing the seat ring 2 has a second opening 13 corresponding to the end of the seat ring 2, into which used membrane sleeves extend and fit onto the recycling reel 32. This facilitates the fitting of unused membrane sleeves onto the seat ring 2 and the recycling of used membrane sleeves, resulting in a simple structure.

[0073] In one embodiment, the driving element can be, but is not limited to, a motor. The driving element is fixedly connected to the base 1 and has a driving shaft, such as... Figure 9 As shown, the recycling reel 32 is provided with a transmission hole 321 for inserting a drive shaft. The drive component is inserted into the recycling reel 32 to drive the recycling reel 32 to rotate. The structure is simple.

[0074] Among them, such as Figure 9 As shown, the cross-sectional shape of the transmission hole 321 can be, but is not limited to, hexagonal, and can also be a polygon such as triangle, quadrilateral, or pentagon.

[0075] In one embodiment, such as Figure 6 and Figure 10 As shown, the membrane sleeve spool 31 is provided with a second connecting hole 311, and the base 1 is provided with a support shaft (not shown in the figure). The second connecting hole 311 is correspondingly provided with the support shaft, and the radial dimension of the connecting rod is slightly smaller than the size of the second connecting hole 311, so that the support shaft can be inserted into the second connecting hole 311 to support and limit the membrane sleeve spool 31, so that the membrane sleeve spool 31 can rotate smoothly in the base.

[0076] like Figure 1 As shown, this application embodiment also provides a toilet, including the toilet seat device of any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0077] like Figure 1 As shown, the toilet also includes a seat 5, and the toilet seat assembly is mounted on the toilet seat 5 via a base 1.
