Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a smart heated toilet. Background Technology

[0002] Smart toilets, also known as smart toilet seats, bring convenience to life. The heated toilet seat is one of the best features of a smart toilet, providing a superior user experience. For example, in cold weather, when the toilet seat is cold, users can adjust the temperature of the heating unit inside the seat to improve comfort while using the toilet.

[0003] Currently, an existing patent (publication number: CN221489822U) discloses a heated toilet, including a toilet with a toilet seat and a movable toilet seat. A connecting rod is located at the rear of the toilet seat, and the toilet seat is hinged to the toilet via the connecting rod. A toilet lid covers the toilet seat and toilet seat. An electric heating wire is installed inside the toilet seat, laid on the inner top wall of the toilet seat. The heating wire transfers heat to the upper surface of the toilet seat through heat transfer. This heated toilet can maintain a certain temperature for the toilet seat, preventing the user from getting cold, and offers high overall safety.

[0004] The aforementioned heated toilet has multiple vents at the bottom of the toilet seat during use. When the temperature inside the toilet seat is high, the gas inside the seat flows out through these vents. However, in the humid environment of a bathroom, these vents also become a pathway for water droplets to enter the toilet seat. Once water enters the toilet seat, it can negatively impact the performance and lifespan of the heating element over time. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an intelligent heated toilet that effectively prevents water droplets from entering the toilet seat through the vent, thereby improving the performance and lifespan of the electric heating wire.

[0006] The present invention adopts the following technical solution:

[0007] A smart heated toilet includes a toilet seat and a toilet seat. The toilet seat is movably mounted on the toilet seat. An electric heating wire is installed inside the toilet seat, and the electric heating wire transfers heat to the upper surface of the toilet seat through heat transfer. Several vent holes communicating with the interior of the toilet seat are opened on the side wall of the toilet seat. A high-temperature resistant, waterproof, and breathable membrane is installed on the toilet seat, covering the vent holes to form a water-blocking barrier. A waterproof flow guiding structure is also provided on the side wall of the toilet seat corresponding to the vent holes. The waterproof flow guiding structure communicates with the outside and the vent holes, and is used to guide water flow away from the vent holes.

[0008] Furthermore, the waterproof drainage structure includes a first drainage slope, a second drainage slope, and a drainage ramp. One end of the first drainage slope is fixed to the side wall of the toilet seat, and the other end of the first drainage slope is connected to one end of the second drainage slope. The other end of the second drainage slope is connected to the upper end of the vent hole. The first and second drainage slopes are set at an angle, and both the first and second drainage slopes slope downwards. The slopes of both the first and second drainage slopes face downwards. The first drainage slope is used to receive water flow from above the toilet seat, and the second drainage slope is used to prevent water flow diverted by the first drainage slope from entering the vent hole. One end of the drainage ramp is connected to the lower end of the vent hole, and the other end of the drainage ramp is fixed to the side wall of the toilet seat. The slope of the drainage ramp faces upwards. The drainage ramp is used to receive water flow from the first drainage slope and to divert water flow below the vent hole.

[0009] Furthermore, the waterproof drainage structure includes an inclined drainage surface and a drainage slope. One end of the inclined drainage surface is connected and fixed to the side wall of the toilet seat, and the other end of the inclined drainage surface is connected to the upper end of the vent hole. The inclined drainage surface is inclined from top to bottom. One end of the drainage slope is connected to the lower end of the vent hole, and the other end of the drainage slope is connected and fixed to the side wall of the toilet seat. The drainage slope is parallel to the inclined drainage surface and is inclined from top to bottom. The slope of the drainage slope faces upwards to guide the water flow below the vent hole.

[0010] Furthermore, a heating pad is provided inside the toilet seat, and the heating pad is connected to an electric heating wire. The heating pad is located on the top wall inside the toilet seat, and the heat generated by the electric heating wire is transferred to the upper surface of the toilet seat through the heating pad.

[0011] Furthermore, it also includes a cable assembly and a circuit board. The cable assembly includes cable A, cable B, a connector, and an NTC thermistor element. The connector is provided with a positive terminal and a negative terminal. One end of cable A is electrically connected to the positive terminal, and the other end of cable A is electrically connected to the positive electrode of the heating wire. One end of cable B is electrically connected to the negative terminal, and the other end of cable B is electrically connected to the negative electrode of the heating wire. The NTC thermistor element is disposed on the connector, and the temperature sensing head of the NTC thermistor element is in contact with the surface of cable A and / or cable B. The NTC thermistor element and the connector are both controlled by the circuit board, and the circuit board is fixed in the receiving cavity provided inside the toilet seat.

[0012] Furthermore, the temperature sensing head of the NTC thermistor element is clamped between cable A and cable B.

[0013] Furthermore, cable A wraps around the temperature sensing head of the NTC thermistor element.

[0014] Furthermore, cable B wraps around the temperature sensing head of the NTC thermistor element in a spiral manner.

[0015] Furthermore, a temperature sensor is provided on the heating pad, and the temperature sensor is controlled by the circuit board. The temperature sensor is used to monitor the temperature of the heating pad in real time.

[0036] Example 1

[0037] Please refer to Figures 1-9 This utility model provides an intelligent heated toilet, including a toilet seat 1 and a toilet ring 2. The toilet ring 2 is movably mounted on the toilet seat 1 and consists of a seat ring 20 and a lower shell 21. The seat ring 20 covers the lower shell 21, and the seat ring 20 and the lower shell 21 are detachably and sealed together. There is an installation space between the seat ring 20 and the lower shell 21, which is the inner cavity of the toilet ring 2. An electric heating wire 3 is provided in the inner cavity of the toilet ring 2. The electric heating wire 3 transfers heat to the upper surface of the toilet ring 2 through heat transfer. Several vent holes 201 communicating with the interior of the toilet ring 2 are opened on the side wall of the seat ring 20. A high-temperature resistant waterproof and breathable membrane 5 is provided on the toilet ring 2, and the waterproof and breathable membrane 5 covers the vent holes 201, forming a water-blocking barrier. Furthermore, a waterproof flow guiding structure 202 is provided on the side wall of the toilet seat 20 corresponding to the vent 201. This waterproof flow guiding structure 202 communicates with the outside environment and the vent 201, and is used to guide water flow away from the vent 201. In this embodiment, the intelligent heated toilet, by providing a high-temperature resistant waterproof and breathable membrane 5 on the vent 201 of the toilet seat 2, forms a water-blocking barrier. Simultaneously, the waterproof flow guiding structure 202 on the toilet seat 2 corresponding to the vent 201 guides water flow away from the vent 201, effectively preventing water droplets or water vapor from entering the toilet seat 2 through the vent 201, thus avoiding water vapor affecting the performance and lifespan of the electric heating wire 3.

[0038] In this embodiment, the temperature of the electric heating wire 3 heating the toilet seat 2 is generally set within a range that is comfortable and safe for the human body. This temperature range is usually between 35°C and 45°C. Within this temperature range, the toilet seat 2 will not be too cold to cause discomfort, nor too hot to cause burns.

[0039] The waterproof and breathable membrane 5 of this embodiment has a high temperature resistance between 200°C and 260°C.

[0040] In one embodiment, the waterproof drainage structure 202 includes a first drainage slope 2020, a second drainage slope 2021, and a drainage ramp 2022. One end of the first drainage slope 2020 is fixed to the side wall of the toilet seat 20. The other end of the first drainage slope 2020 is connected to one end of the second drainage slope 2021. The other end of the second drainage slope 2021 is connected to the upper end of the vent hole 201. Both the first drainage slope 2020 and the second drainage slope 2021 are inclined from top to bottom, and the first drainage slope 2020 and the second drainage slope 2021 are set at an angle. The slopes of the first guide slope 2020 and the second guide slope 2021 both face downwards. The first guide slope 2020 is used to receive water flow from above the toilet seat 2, and the second guide slope 2021 is used to prevent water flow from the first guide slope 2020 from entering the vent hole 201. One end of the guide slope 2022 is connected to the lower end of the vent hole 201, and the other end of the guide slope 2022 is fixed to the side wall of the seat ring 20 of the toilet seat 2. The slope of the guide slope 2022 faces upwards. The guide slope 2022 is used to receive water flow from the first guide slope 2020 and to draw out water flow below the vent hole 201. Therefore, it can be understood that when water flows down the outer wall of the toilet seat 2 from the surface of the toilet seat 2, it will first encounter the first guide slope 2020. The water flows along the slope of the first guide slope 2020. Since the first guide slope 2020 and the second guide slope 2021 are set at an angle, when the water flows along the slope of the first guide slope 2020 to the lower end of the first guide slope 2020, the flow is interrupted at the corner where the second guide slope 2021 connects to the first guide slope 2020. In this way, the water guided by the first guide slope 2020 will enter the guide slope 2022 for discharge, thereby ensuring that the water does not enter the vent 201.

[0041] The waterproof flow guiding structure 202 of this embodiment forms an effective water flow barrier through the design of multiple flow guiding slopes and slopes, ensuring that the water flow is guided away from the vent 201 in multiple directions. This waterproof flow guiding structure 202 is suitable for humid environments or cleaning, and can effectively prevent water from entering the toilet seat 2 through the vent 201, protecting the electronic components or structure inside the toilet seat 2 from damage.

[0042] In one embodiment, a heating pad 4 is provided inside the toilet seat 2. The heating pad 4 is fixed to the top wall inside the seat ring 20 and is connected to an electric heating wire 3. The heat generated by the electric heating wire 3 is transferred to the upper surface of the toilet seat 2 through the heating pad 4. The presence of the heating pad 4 can reduce the damage to the material of the toilet seat 2 caused by sudden temperature changes (such as sudden contact with hot water from a cold environment), thereby extending the service life of the toilet seat 2.

[0043] In one embodiment, the intelligent heated toilet further includes a cable assembly and a circuit board. The cable assembly includes cable A6, cable B7, connector 9, and NTC thermistor element 92. Connector 9 is provided with a positive terminal 90 and a negative terminal 91. One end of cable A6 is electrically connected to the positive terminal 90, and the other end of cable A6 is electrically connected to the positive electrode of the heating wire 3. One end of cable B7 is electrically connected to the negative terminal 91, and the other end of cable B7 is electrically connected to the negative electrode of the heating wire 3. Cables A6 and B7 have the same structure and are both flexible flat cables. The NTC thermistor element 92 is disposed on connector 9, and the temperature sensing head 920 of the NTC thermistor element 92 is in contact with the surface of cable A6 and / or cable B7. Both the NTC thermistor element 92 and connector 9 are controlled by the circuit board (not shown), and the circuit board is fixed in a receiving cavity provided inside the toilet seat 2.

[0044] As can be understood from the above, the NTC thermistor element 92 can monitor the temperature of cable A6 and / or cable B7 in real time, avoiding the heating wire 3 from heating for too long, which would cause the cable to overheat and burn out.

[0045] Of course, the circuit board can be controlled by a remote control or a mobile app to control the switching and temperature adjustment of the electric heating wire 3, thus achieving a convenient operating experience.

[0046] In one embodiment, the temperature sensing head 920 of the NTC thermistor element 92 is clamped between cable A6 and cable B7. The NTC thermistor directly contacts the surfaces of cable A6 and heating cable B7 through its temperature sensing head 920, and senses the surface temperature of heating cable A6 and heating cable B7 in real time. It not only has a fast response speed, but also a short heat conduction path and fast response time, making it suitable for scenarios requiring rapid temperature control.

[0047] In one embodiment, a temperature sensor (not shown) is disposed on the bottom surface of the heating pad 4. The temperature sensor is controlled by the circuit board and is used to monitor the temperature of the heating pad 4 in real time. Therefore, by monitoring and adjusting in real time, the temperature of the heating pad 4 can be ensured to remain within the user-set comfort range, avoiding overheating or undercooling and improving the user experience. When the temperature sensor detects that the temperature of the heating pad 4 exceeds a preset safety threshold, the circuit board will immediately cut off the power supply to the heating wire 3 to prevent the heating pad 4 from overheating and causing a fire or other safety accidents. If the temperature sensor detects abnormal temperature changes (such as a sharp rise or fall in temperature), the circuit board can issue a warning signal to remind the user to check or repair in time to avoid potential safety hazards.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that the waterproof drainage structure 202 is different.

[0050] Reference Figure 10 and Figure 11 In this embodiment, the waterproof drainage structure 202 includes an inclined drainage surface 2023 and a drainage slope 2022. One end of the inclined drainage surface 2023 is connected and fixed to the side wall of the seat ring 20 of the toilet seat 2, and the other end of the inclined drainage surface 2023 is connected to the upper end of the vent hole 201. The inclined drainage surface 2023 is inclined from top to bottom. One end of the drainage slope 2022 is connected to the lower end of the vent hole 201, and the other end of the drainage slope 2022 is connected and fixed to the side wall of the seat ring 20 of the toilet seat 2. The drainage slope 2022 is parallel to the inclined drainage surface 2023. The drainage slope 2022 is inclined from top to bottom, and the slope of the drainage slope 2022 faces upward. The drainage slope 2022 is used to draw out the water flow below the vent hole 201. Therefore, it can be understood that when water flows down the outer wall of the toilet seat 2 from the surface of the toilet seat 2, it will first encounter the inclined guide surface 2023. The water flow will be blocked at the corner where the inclined guide surface 2023 connects with the side wall of the toilet seat 2, and then enter the guide slope 2022 for discharge, thereby effectively ensuring that the water flow will not enter the vent 201.

[0051] Example 3

[0052] Reference Figure 12 The difference between this embodiment and the above embodiment is that the temperature sensing head 920 of the NTC thermistor element 92 is in contact with the surface of the cable A6.

[0053] In this embodiment, cable A6 wraps around the temperature sensor 920 of the NTC thermistor element 92. The temperature of heating cable A6 is monitored in real time by the NTC thermistor element 92. During the heating process of the heating wire, since the temperatures of cable A6 and cable B7 are the same, real-time monitoring of the temperature of heating cable A6 can prevent overheating and burnout of cable A6 or cable B7 during prolonged heating of the heating wire.

[0054] Example 4

[0055] The difference between this embodiment and the above embodiment is that the temperature sensing head 920 of the NTC thermistor element 92 is in contact with the surface of the cable B7.

[0056] Reference Figure 13 In this embodiment, cable B7 wraps around the temperature sensor 920 of the NTC thermistor element 92, allowing the NTC thermistor element 92 to monitor the temperature of heating cable B7 in real time. During the heating process of the heating wire, since cables A6 and B7 have the same temperature, real-time monitoring of the temperature of heating cable B7 prevents overheating and burnout of either cable A6 or B7 during prolonged heating of the heating wire.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
