Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary ware, in particular to a toilet seat cover. Background Art
[0002] A toilet is a common sanitary fixture consisting of a seat and a lid hinged to its end. The seat, which comes into direct contact with the user, is typically made of plastic, ceramic, or a material with a special coating to ensure easy cleaning and durability. The lid, which covers the toilet and usually fits alongside the seat, protects it from dust and dirt. The integrated seat and lid are collectively referred to as a cover plate.
[0003] With the development of intelligent home products, smart toilets are gradually becoming part of people's lives. Evolved from traditional toilets, smart toilets not only have the traditional toilet's good flushing function, but also have other intelligent functions, such as night lighting and heating. The night lighting function is mainly achieved by installing a night light at the hinge connection between the lid and the seat ring. For example, a luminous toilet cover (Announcement No.: CN201870555U) disclosed in the prior art has an LED light-emitting device fixedly mounted on the upper cover (i.e., the lid).
[0004] However, existing technologies often require a heating device built into the toilet seat to provide heating. However, this can negatively impact the lifespan of the night light. This is because the heating device generates heat during operation, and night lights are very sensitive to temperature fluctuations. Sustained high temperatures can accelerate the light decay of the night light, reducing its brightness and lifespan. Furthermore, to conserve power, the heating device and night light may share a single power supply. Improper power supply design can lead to current instability, shortening the lifespan of the night light. Utility Model Content
[0005] The utility model provides a toilet seat cover, which can solve the technical problem that the service life of a night light of a traditional toilet seat is easily reduced when the heating function is used.
[0006] This application provides the following technical solutions:
[0007] A toilet cover comprises a lid, a seat, and a hinged connector for rotatably connecting the lid and the seat; the seat comprises an outer shell with an internal cavity, a heat-insulating layer fixedly arranged at the bottom of the cavity, a heat-dissipating layer fixedly arranged at the top of the cavity, and a heating assembly fixedly arranged between the heat-insulating layer and the heat-dissipating layer; a photoresistor and a nightlight are fixedly mounted at one end of the bottom of the outer shell near the hinged connector; and a control assembly for integrated control of the heating assembly and the nightlight is also included, the control assembly comprising a controller and a temperature sensor connected in series with the controller for monitoring the temperature of the seat.
[0008] Beneficial effects:
[0009] 1. Improve the service life of the night light: The night light is installed at one end of the bottom of the seat ring near the hinge connector. This design makes full use of the natural law of heat flowing upward. Since the heat generated by the heating component mainly rises upward, this can minimize the impact of heat on the service life of the night light. On this basis, the provision of insulation and heat dissipation layers further optimizes thermal energy management. Among them, the insulation layer can effectively isolate the transfer of heat to the installation location of the night light, while the heat dissipation layer accelerates the transfer of heat to the top of the seat ring, ensuring that the heat is concentrated in the area required by the user, further reducing the adverse effects of heat on the night light. The temperature sensor is connected in series with the controller to monitor the temperature changes of the seat ring in real time, and adjust the working status of the heating component through the controller to ensure that the temperature of the seat ring is always maintained within an appropriate range to prevent local overheating problems that cause user discomfort and damage to the night light.
[0010] 2. Improved heating efficiency of the seat: The thermal insulation layer effectively blocks heat conduction to the bottom of the seat, ensuring that heat is concentrated in the area where the user needs it, reducing energy loss and improving heating efficiency. The thermal insulation layer not only ensures that heat is concentrated on the upper surface of the seat, improving user comfort, but also reduces unnecessary energy waste, making the heating component more efficient and economical.
[0011] Further, as an improvement, the heating assembly includes a heating film fixedly arranged between the thermal insulation layer and the heat dissipation layer, a heating wire connected in series with the heating film, and a recoverable fuse and an irreversible fuse connected in series with the heating wire.
[0012] Beneficial Effects: The heating wire and heating film are connected in series, forming a stable heating circuit, ensuring even current distribution and avoiding overheating caused by localized excessive current. This design not only improves heating uniformity and efficiency, but also extends the life of the heating component. The series use of a resettable fuse and a non-resettable fuse provides multiple safety protections for the heating system. The resettable fuse automatically disconnects the circuit when the temperature exceeds a preset value and automatically resets when the temperature drops to a safe range, ensuring the automatic recovery function of the heating component in the event of a temporary abnormality. The non-resettable fuse permanently disconnects the circuit if the temperature remains too high or a serious fault occurs, preventing potential safety hazards and protecting the heating component and the user.
[0013] Furthermore, as an improvement, the thermal insulation layer is a rock wool board.
[0014] Beneficial effects: As a high-performance thermal insulation material, rock wool board has excellent thermal insulation effect, which reduces the heat generated by the heating component from being transferred to the bottom of the seat ring, reducing the adverse effects on the night light installed at the bottom of the seat ring, thereby extending the service life of the night light and allowing it to remain in a constantly lit state for a longer period of time.
[0015] Furthermore, as an improvement, the heat dissipation layer is made of carbon fiber material, and a plurality of micropores for heat dissipation are opened on the heat dissipation layer.
[0016] Benefits: Carbon fiber materials offer excellent thermal conductivity and are lightweight, efficiently transferring heat away from heat sources while maintaining a low weight and not adding to the overall structural burden. Micropores in the heat dissipation layer further enhance airflow and promote rapid heat dissipation. This design not only improves heat dissipation efficiency but also enhances structural strength.
[0017] Furthermore, as an improvement, the control assembly further includes a seat temperature switch for adjusting the seat ring temperature, and the seat temperature switch is fixedly mounted on the side wall of the hinge shaft connector.
[0018] Beneficial effects: Users can flexibly adjust the temperature of the seat ring by adjusting the seat temperature switch according to personal preferences and changes in ambient temperature. The seat temperature switch is installed on the side wall of the hinge connector, with a fixed position, easy to find and simple to operate, which improves the comfort of user experience.

[0024] The following is further described in detail through specific implementation methods:
[0025] The marks in the drawings of the specification include: cover 1, seat ring 2, block 21, shell 22, thermal insulation layer 23, heat dissipation layer 24, heating component 25, heating film 251, heating wire 252, recoverable fuse 253, irreversible fuse 254, control component 26, controller 261, seat temperature switch 262, temperature sensor 263, hinge connector 3, photoresistor 4, night light 5.
[0026] Example 1
[0027] Combine Figure 1-Figure 5 As shown, the toilet cover includes a cover 1, a seat ring 2, and a hinge connector 3 for rotatably connecting the cover 1 and the seat ring 2. A photoresistor 4 and a night light 5 are fixedly installed at one end of the bottom of the seat ring 2 close to the hinge connector 3, and a stop block 21 is fixedly installed at one end of the bottom of the seat ring 2 away from the hinge connector 3. When the seat ring 2 is lowered, the stop block 21 on the seat ring 2 abuts against the upper edge of the top surface of the toilet seat, so that a certain gap is retained between the bottom surface of the seat ring 2 and the top surface of the toilet seat, so that the night light can be emitted.
[0028] In this embodiment, the seat ring 2 includes a shell 22 with an internal cavity, an insulation layer 23, a heat dissipation layer 24, a heating component 25 fixedly arranged between the insulation layer 23 and the heat dissipation layer 24, and a control component 26 for integrated control of the heating component 25 and the night light 5.
[0029] Specifically, the shell 22 is made of ordinary ceramic material, the thermal conductivity of the ceramic material is 1.5W / (m·K), the insulation layer 23 is a rock wool board and is laid at the bottom of the shell 22 cavity, and the thermal conductivity of the rock wool board is about 0.040W / (m·K). The laying of the insulation layer 23 can effectively isolate the heat emitted by the heating component 25 without affecting the night light 5 located at the bottom of the shell 22.
[0030] Specifically, the heat dissipation layer 24 is made of carbon fiber material, and is laid on the bottom of the cavity of the shell 22 . A plurality of micropores for heat dissipation are opened on the heat dissipation layer 24 .
[0031] Specifically, the heating assembly 25 includes a heating film 251 laid between the heat dissipation layer 24 and the insulation layer 23, a heating wire 252 connected in series with the heating film 251, and a resettable fuse 253 and an irresettable fuse 254 connected in series with the heating wire 252. The resettable fuse 253 (also known as a self-resettable fuse) and the irresettable fuse 254 (a one-time fuse) are used in series in the circuit to provide different levels of protection. Among them, when an overcurrent occurs in the circuit, the resettable fuse 253 will rapidly heat up due to the heat generated by the current, causing its resistance value to increase sharply and enter a high-resistance state, thereby limiting the current and protecting other sensitive components in the circuit from damage due to overcurrent. After the fault is eliminated, the resettable fuse 253 will gradually dissipate heat, and the resistance value will decrease accordingly, returning to a low-resistance state, and the circuit will be turned on again, realizing the self-recovery function without the need for manual replacement. On the contrary, when the current exceeds the rated value of the irresettable fuse 254, it will not automatically recover unless a new fuse is replaced.
[0032] Specifically, the control assembly 26 includes a controller 261 and a seat temperature switch 262 for adjusting the temperature of the seat ring 2. The seat temperature switch 262 is connected in series with the controller 261. By adjusting the seat temperature switch 262, the seat ring 2 heating function can be adjusted into three levels: the first level is off, the second level is heated to 35°C, and the third level is heated to 39°C. In this embodiment, the seat temperature switch 262 is mounted on the side wall of the hinge connector 3 using a simple knob to adjust the temperature, eliminating the need for complex setup or adjustment, further enhancing ease of use. The control assembly 26 also includes a temperature sensor 263 for monitoring the temperature of the seat ring 2. The temperature sensor 263 is connected in series with the controller 261. When the temperature sensor 263 detects that the seat ring 2 temperature is abnormally high, for example, a set upper limit of 50°C is set. If the temperature exceeds the upper limit, the circuit on the heating wire 252 is automatically disconnected, stopping heating. The night light 5 and the photoresistor 4 are also connected in series with the controller 261. When the light in the bathroom is dim or absent, the photoresistor 4 enters a high-resistance state, and the night light 5 remains on.
[0033] The above is only an embodiment of the present invention. The present invention is not limited to the field involved in this implementation case. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
