Technical Field

[0001] This utility model relates to the field of smart toilet technology, specifically a fast-heating module for a smart toilet. Background Technology

[0002] As people pay more and more attention to the quality of life, smart sanitary ware is entering more and more homes. As a typical example, smart toilets are becoming increasingly popular in homes and high-end hotels due to their health, comfort, cleanliness and hygiene features. Smart toilets usually have multiple functions, such as bidet function, heated seat, warm air drying, automatic deodorization, and silent seating. Users can operate them through the button panel or remote control to achieve the corresponding functions.

[0003] In existing technologies, because the working environment of toilets is humid, the heating wires in the seat heating components are bound to be damaged after prolonged use. Once the existing smart toilet seat heating function is damaged, the entire seat needs to be disassembled for repair, which is time-consuming and laborious, inconvenient for staff, and affects normal use by users.

[0004] In light of this, we have launched a fast-heating module for smart toilets. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a fast heating module for a smart toilet, including: a toilet 1, a top cover 5 is provided on one side of the top of the toilet 1, and a toilet seat plate 2 is provided on one side of the surface of the top cover 5;

[0031] Toilet seat 3, the toilet seat 3 is disposed on the surface of toilet 1, and a protective pad 13 is disposed on the surface of toilet seat 3;

[0032] A slot 8 is formed inside the toilet seat ring 3. A fixing rod 10 is provided inside the slot 8, and an electric heating strip 9 is provided inside the slot 8 on one side of the fixing rod 10.

[0033] An installation mechanism is provided between the protective pad 13 and the toilet seat 3. The bolts 15 of the installation mechanism are inserted into the interior of the fixing block 11 so that the protective pad 13 is fixed to the surface of the toilet seat 3 to protect the heating strip 9.

[0034] The installation mechanism includes a waterproof plug 14 connected to the surface of the protective pad 13, a fixing block 11 connected at equal intervals inside the slot 8, and bolts 15 connected at equal intervals to the surface of the protective pad 13. The bolts 15 penetrate the protective pad 13 and extend into the fixing block 11. The bolts 15 can install the protective pad 13 onto the surface of the toilet seat 3. The waterproof plug 14 is located on the surface of the bolts 15. The waterproof plug 14 is used to protect the bolts 15 and can also seal the protective pad 13.

[0035] The interior of the hollow slot 8 is connected to a temperature limiter 19 on the surface of the heating strip 9. This limiter uses a negative temperature coefficient (NTC) thermistor, whose resistance decreases as temperature increases. The sensor transmits the temperature signal to the control board, where a microprocessor (MCU) analyzes it in real time. If the temperature exceeds a preset value, the MCU cuts off the power to the heating element. It supports a PID algorithm (proportional-integral-derivative control) to achieve precise temperature control (±1℃), offering high accuracy, strong programmability, and multi-level temperature protection. This technology is commonly used in high-end smart toilets and requires a circuit board to function properly.

[0036] The cavity 8 is equipped with a sensing device located on the surface of the heating strip 9. Through the cooperation of the heat insulation component 12 and the sensing component 16 of the sensing device, the sensing component 16 can sense that the user is sitting on the surface of the toilet seat 3.

[0037] The sensing device includes an installation groove 17 inside the heat insulation component 12. The installation groove 17 and the heat insulation component 12 are integrally formed. The heat insulation component 12 is located inside the hollow groove 8 on the surface of the heating strip 9. The sensing element 16 is connected inside the installation groove 17. The top of the heat insulation component 12 is connected to the seat ring sensing part 7, which is located on the surface of the toilet seat ring 3.

[0038] The surface of the fixing rod 10 is connected to the surface of the heating strip 9 by a heat insulation ring 18. The heat insulation ring 18 can reduce the heat generated by the heating strip 9 from being transferred to the fixing rod 10, improve the heat utilization efficiency, and avoid unnecessary heat loss.

[0039] The surface of the top cover 5 is connected to a display panel 4, which is used to display various working statuses and parameters of the smart toilet, such as the current temperature of the toilet seat 3, heating mode, and other information, so that users can understand them intuitively.

[0040] The surface of the top cover 5 is connected to a shuttle cap 6 on one side of the display panel 4. By rotating or pressing the shuttle cap 6, various functions of the smart toilet can be operated, such as adjusting the seat temperature and switching the heating mode, to achieve convenient human-computer interaction.

[0041] Specifically, during use, when a user approaches or sits on the toilet seat 3, the seat sensor 7 will first be subjected to pressure. The seat sensor 7 is connected to the top of the heat insulation component 12. The heat insulation component 12 has an installation groove 17 inside, and the sensor 16 is installed in the installation groove 17. The seat sensor 7 transmits the pressure to the heat insulation component 12. The heat insulation component 12 plays the role of isolating heat interference and preventing the heat generated by the heating strip 9 from affecting the normal operation of the sensor 16. After sensing the pressure change, the sensor 16 transmits the signal to the control system of the smart toilet, indicating that someone is using the toilet seat 3.

[0042] After plugging in the power cord, the heating element 9 can be activated and put into operation. The heating element 9 is located in the hollow groove 8 inside the toilet seat 3 and is installed on one side of the fixing rod 10. When the heating element 9 is powered on, it will heat up quickly, thereby heating the toilet seat 3 (the temperature can be adjusted between 30°C and 40°C, and a temperature close to human body temperature (about 36°C to 38°C) is usually the most popular), providing users with a warm seat experience. During the heating process, the heat insulation ring 18 on the surface of the fixing rod 10 can reduce the heat generated by the heating element 9 from being transferred to the fixing rod 10, improve heat utilization efficiency, and avoid unnecessary heat loss.

[0043] To ensure that the temperature of the toilet seat ring 3 is within a safe and comfortable range, a thermostat 19 is connected inside the slot 8 to the surface of the heating strip 9. The thermostat 19 monitors the temperature of the heating strip 9 in real time. When the temperature reaches the set upper limit, the thermostat 19 will automatically cut off the power to the heating strip 9 and stop heating. When the temperature drops to a certain level, the thermostat 19 will reconnect the power to allow the heating strip 9 to continue heating. This cycle continues to maintain a stable temperature for the toilet seat ring 3.

[0044] The protective pad 13 is fixed to the surface of the toilet seat 3 by the installation mechanism. The bolts 15 in the installation mechanism are connected to the surface of the protective pad 13 at equal intervals. The slot 8 is connected to the fixing blocks 11 at equal intervals. During installation, the bolts 15 are inserted into the fixing blocks 11 after passing through the protective pad 13, thereby realizing the fixed installation of the protective pad 13. The protective pad 13 can protect the heating strip 9 from external impact or wear, and also provide a more comfortable contact surface for users. The waterproof plug 14 is located on the surface of the bolts 15. It can prevent water from entering the slot 8 through the gap between the bolts 15 and the fixing blocks 11, avoiding damage to the heating strip 9, the sensing device and the temperature limiter 19, etc., and improving the waterproof performance and service life of the entire fast heating module.

[0045] The display panel 4 connected to the surface of the top cover 5 is used to display various working statuses and parameters of the smart toilet, such as the current temperature of the toilet seat 3 and the heating mode, so that users can understand them intuitively. The shuttle cap 6 located on one side of the display panel 4 on the surface of the top cover 5 is an important component for operating the smart toilet. Users can rotate or press the shuttle cap 6 to perform various functions of the smart toilet, such as adjusting the seat temperature and switching the heating mode, so as to achieve convenient human-computer interaction.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
