Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilets, and particularly to an intelligent toilet seat assembly and an intelligent toilet. Background Art

[0002] As an important innovative product in the modern sanitary ware field, intelligent toilets have been gradually popularized and favored by consumers. Among them, functions such as seat heating and warm air drying are one of the core functions of intelligent toilets, which can significantly improve the user's comfort.

[0003] Traditional intelligent toilets usually connect to an external power supply through a power cord to supply power to electrical components. Although this power supply method is simple to use, the external power supply is limited by the location and quantity of indoor power sockets, which will increase the complexity of installation and maintenance during the renovation of old houses or the installation of sanitary wares. To solve this problem, toilets powered by independent rechargeable power supplies have emerged. This technology uses a built-in rechargeable power supply as the independent power source of the toilet, realizing a power supply method without external power connection. However, due to the generally humid use environment of toilets, this poses a challenge to the waterproof performance of the independent power source. To prevent the independent power source from being affected by water ingress and affecting its working performance, the existing independent power sources are usually installed inside the flip base of the toilet seat. Although this design can avoid water ingress into the power source to a certain extent, it makes the installation and removal process of the independent power source cumbersome and complex, causing great inconvenience to users when removing the power source for charging. Therefore, how to ensure the convenient installation of the independent power source while taking into account good waterproof performance has become an urgent technical problem to be solved.

[0004] In addition, the common intelligent toilets on the market generally achieve the seat heating function by setting heating elements (such as heating wires) inside the seat. The heating elements generate heat when powered on to increase the temperature of the seat surface. However, in order to ensure the structural strength and stability of the toilet seat, the wall thickness of traditional seats is usually about 5 - 10 millimeters. The seat with too thick a wall thickness will significantly reduce the heat transfer speed, resulting in a slow rise in the seat surface temperature. It takes a long time for the heat to transfer from the heating element to the seat surface to reach a comfortable temperature (30 - 40°C), and the long waiting time will seriously affect the user experience. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the purpose of the present invention is to provide an intelligent toilet seat assembly that is convenient for installing and removing an independent power source, has excellent waterproof performance, and can effectively improve the heat transfer speed in the toilet seat, shortening the time for heat to transfer from the heating device to the seat body surface.

Specific embodiments

[0070] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0071] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0072] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] Such as Figures 1 to 15As shown in the figure, this embodiment discloses an intelligent toilet seat assembly, which includes a base 1, a toilet lid 2, a toilet seat ring 3, and a power supply device 4. The toilet lid 2 and the toilet seat ring 3 are respectively hinged to the base 1. The base 1 is provided with a battery installation groove 11 with an upward opening, and the power supply device 4 is installed in the battery installation groove 11;

[0074] The battery installation groove 11 is provided with a drain hole 111. The bottom surface of the battery installation groove 11 slopes from the side far away from the drain hole 111 to the side close to the drain hole 111, forming a directional drainage slope. The bottom surface of the battery installation groove 11 is provided with several support ribs 112 arranged at intervals. The top surfaces of the several support ribs 112 are on the same plane and parallel to the horizontal plane. In the present invention, a drainage design is carried out for the battery installation groove 11. Through the cooperation of the inclined bottom surface of the battery installation groove and the drain hole, the accumulated water entering the battery installation groove 11 can be actively guided to drain, avoiding water retention, effectively protecting the power supply device 4, preventing the power supply device 4 from short-circuiting and electrode oxidation, ensuring the stable operation of functions such as seat ring heating and warm air drying in the intelligent toilet, and being beneficial to extending the service life of the power supply device 4. In addition, the top surface of the support rib 112 is parallel to the horizontal plane, which can ensure the stable installation of the power supply device 4, not easy to shake or shift, is beneficial to ensuring the precise contact between the electrodes on the power supply device 4 and the contacts on the battery installation groove 11, ensuring the reliability of the electrical connection, and at the same time not affecting the drainage function, taking into account both stability and waterproofness. Due to the drainage design and support rib design of the battery installation groove 11, the power supply device 4 can be installed in the battery installation groove 11 by a direct insertion method. When charging is required, the power supply device 4 can be pulled out from the battery installation groove 11 for charging, which can greatly reduce the difficulty of installation and disassembly of the power supply device 4 and the complexity of operation. Therefore, it can ensure the convenient installation of the independent power supply 4 while taking into account good waterproof performance.

[0075] The toilet seat ring 3 includes a seat ring body 31, a support seat 32, a bottom cover 33, and a heating device 34. The seat ring body 31 is hinged to the base 1. The seat ring body 31 and the bottom cover 33 are connected. An accommodation cavity 35 is formed between the seat ring body 31 and the bottom cover 33. The heating device 34 and the support seat 32 are both installed in the accommodation cavity 35;

[0076] The area of the seat ring body for contacting the human body is the heating part, and the rest of the area is the non-heating part. The wall thickness (i.e., the thickness) of the heating part is less than the wall thickness of the non-heating part;

[0077] The heating device 34 abuts against the bottom surface of the heating part 311, the top surface of the support seat 32 abuts against the heating device 34, and the bottom of the support seat 32 is connected to the bottom cover 33.

[0078] Through improving the overall structure of the toilet seat ring 3, since the wall thickness of the heating part 311 is relatively thin and the heating device 34 is in close contact with the bottom surface of the heating part 311, the heat transfer efficiency can be effectively improved, enabling the surface of the seat ring body 31 to quickly heat up and reach a comfortable temperature (30 - 40 °C), greatly shortening the heating time of the seat ring surface and enhancing the user experience. Additionally, by providing a support seat 32 in the accommodation cavity 35, with one end of the support seat 32 extending to the heating device 34 and the other end extending to the bottom cover 33, it can provide a supporting effect for the heating part 311 with a relatively thin wall thickness, and improve the overall strength and rigidity of the toilet seat ring 3, enabling the toilet seat ring to withstand large external forces and loads without deformation or damage, thereby extending the service life of the toilet seat ring.

[0079] Preferably, the wall thickness of the heating part 311 ≤ 2 mm, within this wall thickness range, the heat transfer efficiency can be effectively improved. It should be noted that the wall thickness of the heating part 311 refers to the distance from the inner surface to the outer surface of the heating part 311, and can also be referred to as the thickness of the heating part.

[0080] Preferably, the angle of inclination of the bottom surface of the battery installation groove 11 from the side away from the drain hole 111 to the side close to the drain hole 111 is 1° - 15°, which has a better drainage effect and is conducive to the reliable installation of the power supply device 4. Specifically, the inclination angles are 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, but are not limited thereto.

[0081] More preferably, the angle of inclination of the bottom surface of the battery installation groove 11 from the side away from the drain hole 111 to the side close to the drain hole 111 is 2° - 8°.

[0082] In one embodiment, the base 1 is provided with a drainage groove 12, the drainage groove 12 is located on the outer periphery of the battery installation groove 11, and the drainage groove 12 communicates with the drain hole 111;

[0083] The power supply device 4 includes a lifting cover 41 and a power supply main body 42. The lifting cover 41 is installed on the top of the power supply main body 42. The periphery of the lifting cover 41 protrudes from the periphery of the power supply main body 42. The bottom surface periphery of the lifting cover 41 is provided with a convex guiding part 411 that cooperates with the drainage groove 12, and the convex guiding part 411 is inserted into the drainage groove 12.

[0084] Through the cooperation of the drainage groove 12 and the convex diversion part 411, the water dripping onto the surface of the lifting cover 41 can be quickly introduced into the drainage groove 12 and discharged through the drainage hole 111, preventing water from entering the battery installation groove 11 and further improving the waterproof performance. Among them, the cooperation of the drainage groove 12 and the convex diversion part 411 forms a physical barrier to further block water from entering the battery installation groove 11, enhancing the protection ability of the intelligent toilet seat cover assembly.

[0085] In one embodiment, the lifting cover 41 includes a first inclined portion 412 and a second inclined portion 413 that are smoothly connected to each other. The first inclined portion 412 is located on the side of the lifting cover 41 close to the toilet seat ring 3. The first inclined portion 412 is inclined from the side away from the toilet seat ring 3 to the side close to the toilet seat ring 3, and the second inclined portion 413 is inclined from the side close to the toilet seat ring 3 to the side away from the toilet seat ring 3.

[0086] The drainage groove 12 includes a first drainage section 121 and second drainage sections 122 provided on the left and right sides of the battery installation groove 11. The first drainage section 121 is provided on the side of the battery installation groove 11 close to the toilet seat ring 3. The second drainage sections 122 are communicated with the first drainage section 121, and the first drainage section 121 is communicated with the drainage hole 111.

[0087] When there is water on the surface of the lifting cover 41, the water can flow along the surface of the first inclined portion 412 in the direction close to the first drainage section 121 and fall into the first drainage section 121. Based on the communication between the first drainage section 121 and the drainage hole 111, the water can be discharged to the outside of the battery installation groove 11 through the drainage hole 111, preventing water from entering the battery installation groove 11; or the water on the surface of the lifting cover 41 can also flow along the surface of the second inclined portion 413 and flow to the outside of the base, avoiding the water on the surface of the lifting cover 41 from entering the battery installation groove 11.

[0088] The present invention can respectively guide the water on the surface of the lifting cover 41 to flow into the drainage groove or to the outside of the base through the first inclined portion 412 and the second inclined portion 413. The dual waterproof paths ensure that water will not enter the battery installation groove 11. The first drainage section 121 and the second drainage sections 122 cover multiple directions of the battery installation groove 11 to ensure all-round drainage and improve the waterproof reliability.

[0089] In one embodiment, a drainage groove 13 is provided inside the base 1. The drain hole 111 communicates with the input end of the drainage groove 13, and the output end of the drainage groove 13 communicates to the outside of the base 1. Through the cooperation of the drainage groove 12, the drain hole 111 and the drainage groove 13, the accumulated water in the battery installation groove 11 and the water dripping onto the surface of the lifting cover 41 can be discharged to the outside of the base 1, forming a complete drainage path, completely avoiding the problem of accumulated water, and ensuring the safety and stability of the power supply device 4.

[0090] In one embodiment, a plurality of limiting strips 113 are provided on the side wall of the battery installation groove 11. The plurality of limiting strips 113 are spaced apart and installed on the side wall of the battery installation groove 11. A power supply main body installation space is formed between the plurality of limiting strips 113 and the plurality of supporting ribs 112, and the size of the power supply main body installation space is adapted to the size of the power supply main body 42.

[0091] The power supply main body installation space formed by the cooperation between the limiting strip 113 and the supporting rib 112 ensures the accuracy of the installation position of the power supply main body 42, avoids shaking or deviation, enables the electrodes on the power supply main body 42 (i.e., the discharge negative electrode (P-), the charging negative electrode (C-), and the charge and discharge positive electrode (C+ / P+)) to be in precise contact with the contacts on the battery installation groove 11 (i.e., the first elastic conductive contact 141, the second elastic conductive contact 142, and the third elastic conductive contact 143), improves the stability and safety of the entire power supply device 4, and thus supplies power to various electrical appliances.

[0092] In one embodiment, the limiting strip 113 includes a guiding portion (not labeled in the figure) and a limiting portion (not labeled in the figure). The guiding portion is installed on the top of the limiting portion, and the guiding portion and the limiting portion are smoothly and transitionally connected.

[0113] In one embodiment, the heating device 34 includes two electrothermal films 341 that are symmetrically arranged and connected in series, and a heat insulation layer 342 is provided at the bottom of each electrothermal film 341;

[0114] The shapes of the heating part 311, the electrothermal film 341 and the support seat 32 match each other. The top surface of the electrothermal film 341 abuts against the bottom surface of the heating part 311, and the top of the support seat 32 abuts against the bottom surface of the heat insulation layer 342.

[0115] Since the top surface of the electrothermal film 341 abuts against the bottom surface of the heating part 311, and a heat insulation layer 342 is provided at the bottom of the electrothermal film 341, heat can be effectively blocked from being transferred to non-target areas (i.e., downward transfer), reducing heat loss, so that the heat generated by the electrothermal film 341 is transferred in the direction close to the heating part 311, realizing precise heating of the heating part 311, which can further increase the heating speed of the surface of the seat ring body 31 and further shorten the time for the surface of the seat ring body 31 to reach the target temperature.

[0116] It should be noted that the heating device 34 adopts an innovative double-piece heating structure, and two separately arranged electrothermal films 341 are used to replace the traditional integral ring-shaped heating device. During actual assembly, the two electrothermal films 341 can be independently installed on the left and right sides inside the toilet seat ring respectively. The double-piece structure can be flexibly adjusted according to the specific dimensions of different models of toilet seat rings. By adjusting the distance or angle between the two electrothermal films, a good match with various specifications of seat rings can be achieved, greatly improving the versatility of the product; moreover, the split design simplifies the installation process and reduces the assembly difficulty, which is particularly suitable for standardized operations on production lines of different-sized seat rings; in addition, when a single electrothermal film fails, only the corresponding module needs to be replaced, without the need for overall replacement, which can significantly reduce the maintenance cost. This double-piece heating structure can effectively solve the technical problems of poor adaptability and low versatility of the traditional integral ring-shaped heating device, and provides a more flexible solution for the heating system of intelligent toilet seat rings.

[0117] By connecting the first electrothermal film 1 and the second electrothermal film 2 in series, the series structure ensures that the current passing through the two electrothermal films is the same, which can improve the even heat distribution of the two electrothermal films. Moreover, the series structure increases the total resistance of the heating device, which can further improve the heating speed of the heating device.

[0118] Preferably, the heating device is also provided with a fuse, a temperature detector and a temperature protector (not marked in the figure).

[0119] In one embodiment, the wall thickness of the heating part 311 is 0.3 mm to 1.5 mm. This can further improve the heat transfer speed, quickly raise the temperature of the surface of the seat ring body 31, and reach a comfortable temperature (30 - 40 °C), further shortening the time for the surface of the seat ring body 31 to reach the target temperature and further enhancing the comfort and experience of the user. It should be noted that the wall thickness of the heating part 311 should not be less than 0.3 mm. An overly thin thickness will make it difficult for the heating part 311 to be formed during the preparation of the seat ring body 31, reducing the qualified rate of the production of the seat ring body 31.

[0120] In some embodiments, the wall thickness of the heating part 311 can also be 1 mm to 2 mm. Within this thickness range, the heat transfer speed is within a suitable range, which is beneficial to the formation of the heating part 11 when preparing the seat ring body 1 and enables the heating part 11 to obtain a certain strength and is not easily deformed.

[0121] Specifically, the wall thickness of the heating part 11 is exemplarily 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, but not limited thereto.

[0122] More preferably, the wall thickness of the heating part 311 is 0.3 mm to 1 mm. Within this range, the wall thickness of the heating part 311 is relatively thin, which can further improve the heat transfer speed, make the surface of the seat ring body 31 heat up more quickly, and reach a comfortable temperature (30 - 40 °C), further shortening the time for the surface of the seat ring body 31 to reach the target temperature.

[0123] In one embodiment, the heating parts 311 are respectively arranged on the left and right sides of the seat ring body 31, and the heating parts 311 are located at the top of the seat ring body 31.

[0124] The bottom surface of the seat ring body 31 corresponding to the heating part 311 is recessed upward to form a heating groove 312, that is, the upper wall of the heating groove 312 is the bottom surface of the heating part 311, and the electrothermal film 341 is installed in the heating groove 312.

[0125] Preferably, the electrothermal film 341 is pasted on the bottom surface of the heating part 311 by pasting, which can achieve close contact, reduce energy loss, and improve the heat transfer effect.

[0126] In one embodiment, the support base 32 includes a bearing panel 321 and a support part 322. The support part 322 is installed at the bottom of the bearing panel 321, and the bottom of the support part 322 is connected to the bottom cover 33;

[0127] The top of the bearing panel 321 extends into the heating groove 312, and the top surface of the bearing panel 321 abuts against the bottom surface of the heating device 34. The support base 32 of this embodiment can stably support the heating part 311 and improve the overall strength and rigidity of the toilet seat ring.

[0128] In one embodiment, the support part 322 is composed of several reinforcing ribs. By reasonably designing the layout and shape of the reinforcing ribs, the amount of material used can be reduced while ensuring the strength and rigidity of the toilet seat ring. Because the reinforcing ribs can significantly improve the strength and rigidity of the toilet seat ring without increasing the overall thickness of the toilet seat ring, thus realizing lightweight design, reducing production costs, and also being beneficial to resource conservation and environmental protection.

[0129] In one embodiment, the seat ring body 31 is provided with a clamping part 313 on the outer periphery of the heating groove 312, and the outer periphery of the bearing panel 321 is provided with a limiting groove 3211, and the clamping part 313 and the limiting groove 3211 are clamped together. Through the cooperation of the clamping part 313 and the limiting groove 3211, the displacement of the support base 32 can be effectively prevented, and a better support effect can be achieved, avoiding deformation or damage of the heating part 311, further improving the overall strength and rigidity of the toilet seat ring, and extending the service life of the toilet seat ring.

[0130] Preferably, the electrothermal film 341 is a graphene electrothermal film or a metal electrothermal film.

[0131] In one embodiment, the electrothermal film 341 includes a pasting layer 3411, a first insulating layer 3412, a heating layer 3413, and a second insulating layer 3414 arranged in sequence; during actual assembly, the electrothermal film 341 is firmly fixed on the bottom surfaces of the heating parts 311 on the left and right sides of the seat ring body respectively through the pasting layer 3411. This installation method ensures that the electrothermal film 341 is in close contact with the contact surface of the seat ring, and can maximize the heat conduction efficiency.

[0132] The heating layer 3413 includes an adhesive layer 34131 and a heating element 34132 embedded in the adhesive layer 34131. The heating element 34132 is arranged in a serpentine and circuitous manner within the adhesive layer 34131.

[0133] The material of the adhesive layer 34131 is an adhesive material. Utilizing the material properties of the adhesive layer 34131, it can not only firmly fix the heating element 34132 but also effectively achieve a tight connection between the heating layer 3413, the first insulating layer 3412, and the second insulating layer 3414. After the adhesive layer 34131 is cured, the first insulating layer 3412, the heating layer 3413, and the second insulating layer 3414 together form a sealed and highly insulating sandwich structure, which can significantly prevent the contact between external water vapor and the heating element 34132, while greatly enhancing the overall insulation performance, thereby ensuring the safe and stable operation of the heating device.

[0134] Preferably, the material of the adhesive layer 34131 is selected to be a material with good thermal stability and insulating properties. In some embodiments, the material of the adhesive layer 34131 can be a high-temperature resistant epoxy resin, but it is not limited thereto.

[0135] Preferably, the shape of the electrothermal film 341 is arc-shaped; the symmetrical and double-arc design can not only make the electrothermal film 341 better adapt to the shape of the seat ring, but also, after the two electrothermal films 341 are installed inside the toilet seat ring, can more precisely match the human contact area, quickly heat the human contact area on the toilet seat ring, reduce heat dissipation, and improve the heating efficiency.

[0136] In one embodiment, the heating element 34132 includes a first heating wire 341321 and a second heating wire 341322. The starting end of the first heating wire 341321 is connected to the starting end of the second heating wire 341322, and the connection point forms a first welding wire area 341323; the terminating end of the first heating wire 341321 is connected to the terminating end of the second heating wire 341322, and the connection point forms a second welding wire area 341324;

[0137] The first heating wire 341321 and the second heating wire 341322 are respectively arranged in the front and rear regions of the adhesive layer 34131 in a serpentine and circuitous manner.

[0138] The first heating wire 341321 and the second heating wire 341322 are respectively arranged in a serpentine and circuitous manner at different parts of the heating layer 3413, and after the first heating wire 341321 and the second heating wire 341322 are arranged, they cover the entire heating layer 3413, which can achieve large-area uniform heating, make the heat evenly dissipated in the area covered by the heating layer 3413, avoid local overheating or overcooling, improve the uniformity and stability of heating, and is beneficial to improving the overall performance and reliability of the heating device. The serpentine and circuitous arrangement method can increase the length of the heating wire in a limited space, thereby increasing the heating power without increasing too much volume, further increasing the heating speed, and effectively utilizing the space to make the structure of the heating element more compact. At the same time, this arrangement method increases the contact area between the heating element 34132 and the upper inner wall of the seat ring, which is beneficial to the rapid dissipation of heat, improves the heat dissipation efficiency, and further enables the upper surface of the seat ring to quickly rise to the target temperature.

[0139] Preferably, the materials of the first heating wire 341321 and the second heating wire 341322 are one of graphene, metallic element and metal alloy. In some embodiments, the metallic element can be copper, and the metal alloy can be nickel-chromium alloy, iron-chromium-aluminum alloy, copper-nickel alloy, etc.

[0140] Preferably, the materials of the first insulating layer 3412 and the second insulating layer 3414 are both PET film or PI film.

[0141] PI film, that is, polyimide film (Polyimide Film), is a high-performance film material with excellent high-temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation performance, and can be used for a long time in the temperature range of -269°C to 400°C.

[0142] In some embodiments, the material of the adhesive layer 3411 is double-sided tape.

[0143] Preferably, the thickness of the electrothermal film 341 is 0.24 mm to 0.8 mm. This thickness range can achieve rapid heat conduction, enable the heat generated by the electrothermal film 341 to be quickly transferred to the upper surface of the toilet seat ring, further shorten the heating waiting time, and avoid the temperature rise lag phenomenon caused by being too thick. Moreover, within this thickness range, sufficient mechanical strength can be maintained to ensure that the heating film does not deform or crack during long-term use, and at the same time maintain good flexibility to adapt to the curved surface of the seat ring.

[0144] In one embodiment, the material of the heat insulation layer 342 is one of nano-aerogel film, microporous polyimide film and porous vacuum silicon film. These materials all have better heat insulation and high-temperature resistance performance, can effectively block the heat transfer to non-target areas (that is, downward transfer), and have a certain flexibility to adapt to the curved surface seat ring.
