Description

Technical Field

[0001] This utility model relates to the field of smart bathroom technology, and in particular to a drying device for a smart toilet, a smart toilet seat, and a smart toilet. Background Technology

[0002] With the improvement of people's living standards and the development of technology, smart home devices are gradually becoming more and more popular. Among them, smart toilets, as one of the important devices for improving the quality of life, have received increasing attention. Smart toilets not only have traditional washing functions, but also integrate a variety of intelligent functions such as seat heating, automatic lid opening, and drying, providing users with a more comfortable and hygienic user experience.

[0003] A drying device is a crucial component of smart toilets, designed to quickly dry the user's skin by blowing hot air, avoiding the inconvenience and hygiene issues associated with wiping with paper towels. However, existing smart toilet drying devices suffer from problems in practical use, such as low drying efficiency, high energy consumption, insufficient hygiene, or limited functionality, failing to further enhance the user experience.

[0004] The above information disclosed in the background section of this application is only for understanding the background of the concept of this application and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a drying device, a smart toilet seat, and a smart toilet to address the above-mentioned problems.

[0006] A drying device for a smart toilet, comprising:

[0007] The outer casing has an internal air duct that extends through the casing and forms mutually spaced air inlets and outlets.

[0008] A heating element is disposed within the air duct;

[0009] A vortex fan is provided on the side of the heating element near the air inlet. The vortex fan is used to draw air in from the air inlet and heat the air through the heating element before blowing it out from the air outlet.

[0010] The drying device for smart toilets described in this application achieves at least the following beneficial effects: By employing a vortex fan, air is efficiently drawn in through rotation upon entering the fan and accelerated within the air duct. This design significantly increases airflow speed and heat exchange efficiency, enabling the heating element to quickly heat the air and blow out uniform, powerful hot air from the outlet, thus achieving a highly efficient drying effect. Compared to ordinary axial fans, vortex fans provide higher airflow and more stable airflow at the same power, significantly shortening drying time and improving user experience. The vortex fan's rotational intake and accelerated airflow within the air duct significantly improves the heat dissipation efficiency of the heating element. Compared to ordinary axial fans, vortex fans transfer heat to the air more effectively, preventing overheating of the heating element and extending the device's lifespan.

[0011] In some embodiments, the drying device for a smart toilet also includes a filter covering the air inlet. The filter filters out particulate matter from the air, ensuring cleaner air entering the duct and preventing the blown-out hot air from carrying impurities, thus improving the user's hygiene experience. The filter design is particularly important in scenarios with high hygiene requirements, such as smart toilets. The filter effectively blocks dust, hair, fibers, and other foreign objects from entering the duct, preventing them from entering the vortex fan or heating components, avoiding fan blade jamming or damage to the heating components due to dust accumulation, thereby reducing device operating efficiency or causing malfunctions, extending the device's lifespan, and reducing maintenance costs. The filter can also be removable, allowing users to easily remove and clean it periodically to maintain its filtering effect. This design simplifies daily maintenance and further enhances the user experience.

[0012] In some embodiments, the filter screen has multiple through holes, each of which has a hexagonal cross-sectional profile.

[0013] In some embodiments, the cross-sectional profile of each of the through holes is a regular hexagon.

[0014] The hexagonal geometry allows for a greater number of perforations per unit area while maintaining high airflow efficiency. The hexagonal perforations maximize airflow, a feature validated by fluid dynamics simulations. This design maximizes the filter area, minimizing airflow resistance and improving the overall performance of the drying unit. The honeycomb arrangement of the hexagons ensures more uniform airflow, preventing localized areas of excessively strong or weak airflow. This uniform airflow distribution contributes to improved drying stability and comfort, providing a better user experience. The hexagonal shape is highly symmetrical and stable, effectively dispersing stress and enhancing the overall strength and durability of the filter. This design prevents deformation or damage during long-term use, extending the unit's lifespan. The hexagonal perforation design creates a smoother filter surface, preventing dust and impurities from accumulating at the perforation edges, simplifying cleaning. Users can easily remove dirt from the filter with simple rinsing or wiping, maintaining its filtration performance.

[0015] In some embodiments, the plurality of through holes are evenly distributed.

[0016] In some embodiments, the housing includes a detachably connected first housing and a second housing that enclose the air duct. The first and second housings enclose the air duct, and a reasonable connection method (such as clips, screws, etc.) ensures the airtightness of the air duct, preventing airflow leakage. The detachable connection of the first and second housings allows users to easily disassemble the housing for cleaning and maintenance of the air duct interior. This design is particularly suitable for drying devices in smart toilets, as dust, scale, or other impurities may accumulate inside the air duct; the detachable structure effectively solves this problem, extending the device's lifespan. The detachable first and second housings make the assembly of the drying device more convenient, reducing production difficulty and cost. In case of equipment failure, maintenance personnel can quickly disassemble the housing to inspect and replace internal components, improving maintenance efficiency and reducing maintenance costs.

[0017] In some embodiments, the drying device for a smart toilet further includes a motor located within the air duct, between the vortex fan and the heating element. The motor is connected to and drives the vortex fan to rotate. A high-speed motor can be used. By placing the motor within the air duct, the connection distance between the motor and the fan is shortened, further optimizing the stability and efficiency of power transmission. Positioning the motor between the vortex fan and the heating element fully utilizes the space within the air duct, making the overall structure of the drying device more compact and saving installation space. This layout helps reduce the size of the device, making it more suitable for integration into a smart toilet while maintaining aesthetics and practicality. The motor's location between the vortex fan and the heating element ensures that the airflow drawn in by the fan first passes over the high-speed motor, providing cooling, before passing over the heating element for heating. This not only cools the motor but also simultaneously utilizes the heat generated by the motor to heat the airflow, reducing energy waste and aligning with green environmental protection principles, thus lowering the overall energy consumption of the smart toilet.

[0018] In some embodiments, the drying device for a smart toilet further includes a temperature sensor disposed within the air duct and located at one end of the air duct near the air outlet. The temperature sensor, located at the end of the air duct near the air outlet, can monitor the airflow temperature at the air outlet in real time.

[0019] In some embodiments, the heating element includes a cylinder, a heating wire, and an NTC thermistor. The cylinder is disposed within the air duct, the heating wire is disposed within the cylinder, and the NTC thermistor is embedded within the cylinder. The NTC thermistor can adjust the heating power of the heating wire based on the temperature data of the air outlet detected by the temperature sensor. The NTC thermistor embedded within the cylinder can monitor the temperature of the heating element in real time and dynamically adjust the heating power of the heating wire based on the air outlet temperature data detected by the temperature sensor. This dual temperature monitoring and feedback mechanism ensures precise control of the drying temperature, avoiding excessively high or low temperatures and improving user comfort. The NTC thermistor can promptly detect abnormal temperatures in the heating element and automatically reduce or cut off the power of the heating wire when the temperature exceeds the safe range, preventing overheating and avoiding burns to users or damage to the equipment. This design significantly improves the safety performance of the drying device and reduces usage risks. The NTC thermistor prevents the heating wire from being at high temperatures for extended periods, thereby extending the service life of the heating element and other related components, helping to reduce equipment maintenance costs and failure rates.

[0020] In some embodiments, the drying device for a smart toilet further includes a negative ion generator. The negative ion generator is located on the side of the cylinder near the air outlet, and a needle-shaped electrode is formed on the side of the negative ion generator facing away from the cylinder. This needle-shaped electrode applies high voltage to the water in the air duct to atomize the water and generate negative ions. Negative ions purify the air, adsorbing dust, bacteria, and odors, thereby improving the air quality around the smart toilet and providing users with a fresher and healthier experience. Negative ions neutralize positive ions in the air, reducing static electricity and dryness, making the skin and respiratory tract more comfortable. During the drying process, the release of negative ions further enhances the user experience, especially in dry seasons or in polluted environments. Negative ions have antibacterial and disinfecting properties, inhibiting the growth of bacteria and viruses and reducing hygiene risks around the smart toilet. This design is particularly suitable for devices like smart toilets that come into direct contact with the human body, further improving hygiene levels.

[0021] This application also provides a smart toilet seat, which includes a core base, a flip cover, a seat ring, and a drying device for a smart toilet as described in any of the above embodiments, wherein the flip cover and the seat ring are rotatably connected to the core base, and the drying device is disposed on the core base.

[0022] The aforementioned smart toilet seat, because it includes the drying device for a smart toilet as described in any of the above embodiments, also has at least the following beneficial effects: By employing a vortex fan, air is efficiently drawn in through rotation upon entering the fan and accelerated within the air duct. This design significantly increases the airflow speed and heat exchange efficiency, enabling the heating element to quickly heat the air and blow out uniform and powerful hot air from the outlet, thereby achieving an efficient drying effect. Compared to ordinary axial fans, vortex fans can provide higher airflow and more stable airflow at the same power, significantly shortening the drying time and improving the user experience. The vortex fan's rotational intake and accelerated airflow within the air duct significantly improves the heat dissipation efficiency of the heating element. Compared to ordinary axial fans, vortex fans can more effectively transfer heat to the air, avoiding overheating of the heating element and extending the device's lifespan.

[0023] This application also provides a smart toilet, which includes a toilet seat and a smart toilet lid as described in any of the above embodiments, wherein the smart toilet lid is disposed on the toilet seat.

[0024] The aforementioned smart toilet, because it includes the smart toilet seat described in any of the above embodiments, also includes at least the following beneficial effects: By employing a vortex fan, air is efficiently drawn in through rotation upon entering the fan and its flow is accelerated within the air duct. This design significantly increases the airflow speed and heat exchange efficiency, enabling the heating element to quickly heat the air and blow out uniform and powerful hot air from the outlet, thereby achieving an efficient drying effect.

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] Please see Figures 1 to 5 In some embodiments, this application provides a drying device 11 for a smart toilet, which includes a housing 100, a heating element 200, and a vortex fan 300. The housing 100 has an air duct 130 extending through it, forming a mutually spaced air inlet 131 and an air outlet 132. The heating element 200 is disposed within the air duct 130. The vortex fan 300 is located on the side of the heating element 200 near the air inlet 131, and is used to draw air in through the air inlet 131, heat it through the heating element 200, and then blow it out through the air outlet 132.

[0035] The drying device 11 for a smart toilet described in this application achieves at least the following beneficial effects: By employing a vortex fan 300, air is efficiently drawn in through rotation upon entering the fan and accelerated within the air duct 130. This design significantly increases airflow velocity and heat exchange efficiency, enabling the heating element 200 to quickly heat the air and blow out uniform, powerful hot air from the outlet 132, thereby achieving a highly efficient drying effect. Compared to ordinary axial fans, the vortex fan 300 provides higher airflow and more stable airflow at the same power, significantly shortening drying time and improving user experience. The vortex fan 300 significantly improves the heat dissipation efficiency of the heating element 200 by drawing in air through rotation and accelerating its flow within the air duct 130. Compared to ordinary axial fans, the vortex fan 300 can more effectively transfer heat to the air, preventing overheating of the heating element 200 and extending the device's lifespan.

[0036] like Figure 4 and Figure 5 As shown, in some embodiments, the drying device 11 for a smart toilet also includes a filter 400 covering the air inlet 131. The filter 400 filters airborne particles, ensuring cleaner air entering the air duct 130, thus preventing the blown-out hot air from carrying impurities and improving the user's hygiene experience. The design of the filter 400 is particularly important in scenarios with high hygiene requirements, such as smart toilets. The filter 400 effectively blocks dust, hair, fibers, and other foreign objects from entering the air duct 130, preventing them from entering the vortex fan 300 or the heating element 200, avoiding fan blade jamming or damage to the heating element 200 due to dust accumulation, thereby reducing device operating efficiency or causing malfunctions, extending the device's lifespan, and reducing maintenance costs. The filter 400 can also be designed to be removable, allowing users to easily and periodically disassemble and clean it to maintain its filtering effect. This design simplifies daily maintenance and further enhances the user experience.

[0037] like Figure 5 As shown, in some embodiments, the filter 400 has multiple through holes 410, each of which has a hexagonal cross-sectional profile. Further, in some embodiments, the multiple through holes 410 are evenly distributed, and each of which has a regular hexagonal cross-sectional profile. The regular hexagonal geometry allows for a greater number of through holes 410 to be arranged per unit area while maintaining high airflow efficiency. The regular hexagonal through holes 410 have the largest airflow, as verified by simulated fluid dynamics. This design maximizes the filtration area of ​​the filter 400, ensuring minimal airflow resistance and thus improving the overall performance of the drying device. The honeycomb arrangement of the regular hexagons makes airflow more uniform, avoiding situations where local airflow is too strong or too weak. This uniform airflow distribution helps improve the stability and comfort of the drying effect, providing a better user experience. The regular hexagon is a highly symmetrical and stable geometric shape; its structure effectively disperses stress, enhancing the overall strength and durability of the filter 400. This design makes the filter screen 400 less prone to deformation or damage during long-term use, extending the lifespan of the device. The design of the regular hexagonal through holes 410 makes the surface of the filter screen 400 smoother, preventing dust and impurities from accumulating at the edges of the through holes 410, thus simplifying the cleaning process. Users can easily remove dirt from the filter screen 400 with a simple rinse or wipe, maintaining its filtration performance.

[0038] like Figure 3 and Figure 4As shown, in some embodiments, the outer casing 100 includes a detachably connected first casing 110 and second casing 120, which enclose the air duct 130. The first casing 110 and second casing 120 enclosing the air duct 130 can ensure the airtightness of the air duct 130 and prevent airflow leakage through a reasonable connection method (such as clips, screws, etc.). The detachable connection of the first casing 110 and second casing 120 allows users to easily disassemble the outer casing 100 to clean and maintain the interior of the air duct 130. This design is particularly suitable for the drying device 11 of a smart toilet, as dust, scale, or other impurities may accumulate inside the air duct 130; the detachable structure effectively solves this problem and extends the service life of the device. The detachable first casing 110 and second casing 120 make the assembly of the drying device more convenient, reducing production difficulty and cost. In the event of a device malfunction, maintenance personnel can quickly disassemble the outer casing 100 to inspect and replace internal components, improving maintenance efficiency and reducing maintenance costs.

[0039] like Figure 5 As shown, in some embodiments, the drying device 11 for a smart toilet further includes a motor 500 disposed within the air duct 130. The motor 500 is located between the vortex fan 300 and the heating element 200. The motor 500 is connected to the vortex fan 300 and drives the vortex fan 300 to rotate. The motor 500 can be a high-speed motor. By placing the motor 500 within the air duct 130, the connection distance between the motor 500 and the fan is shortened, further optimizing the stability and efficiency of power transmission. Positioning the motor 500 between the vortex fan 300 and the heating element 200 fully utilizes the space within the air duct 130, making the overall structure of the drying device more compact and saving installation space. This layout helps reduce the size of the device, making it more suitable for integration into a smart toilet while maintaining aesthetics and practicality. The motor 500 is located between the vortex fan 300 and the heating element 200, ensuring that the airflow drawn in by the fan first passes through the location of the high-speed motor 500 to dissipate heat from it. Then, the airflow passes through the heating element 200 to heat up. This not only cools the motor 500 but also utilizes the heat generated by the motor 500 to heat the airflow, reducing energy waste and conforming to the concept of green environmental protection, thus reducing the overall energy consumption of the smart toilet.

[0040] like Figure 4 and Figure 5As shown, in some embodiments, the drying device 11 for a smart toilet further includes a temperature sensor 600, which is disposed within the air duct 130 and located at one end of the air duct 130 near the air outlet 132. The temperature sensor 600, located at the end of the air duct 130 near the air outlet 132, can monitor the airflow temperature at the air outlet 132 in real time.

[0041] like Figure 5 As shown, in some embodiments, the heating element 200 includes a cylinder 210, a heating wire 220, and an NTC thermistor 230. The cylinder 210 is disposed within the air duct 130, the heating wire 220 is disposed within the cylinder 210, and the NTC thermistor 230 is embedded within the cylinder 210. The NTC thermistor 230 can adjust the heating power of the heating wire 220 based on the temperature data of the air outlet 132 detected by the temperature sensor 600. The NTC thermistor 230, embedded within the cylinder 210, can monitor the temperature of the heating element 200 in real time and dynamically adjust the heating power of the heating wire 220 in conjunction with the temperature data of the air outlet 132 detected by the temperature sensor 600. This dual temperature monitoring and feedback mechanism ensures precise control of the drying temperature, avoids excessively high or low temperatures, and improves user comfort. The NTC thermistor 230 can promptly detect abnormal temperatures in the heating element 200 and automatically reduce or cut off the power of the heating wire 220 when the temperature exceeds the safe range. This prevents the equipment from overheating, avoiding burns to users or damage to the equipment. This design significantly improves the safety performance of the drying device and reduces usage risks. The NTC thermistor 230 also prevents the heating wire 220 from remaining at high temperatures for extended periods, thereby extending the lifespan of the heating element 200 and other related components, helping to reduce equipment maintenance costs and failure rates.

[0042] like Figure 5As shown, in some embodiments, the drying device 11 for a smart toilet further includes a negative ion generator 700. The negative ion generator 700 is located on the side of the cylinder 210 near the air outlet 132, and a needle-shaped electrode 710 is formed on the side of the negative ion generator facing away from the cylinder 210. The needle-shaped electrode 710 can apply high voltage to the water in the air duct 130 to atomize the water and generate negative ions. Negative ions purify the air, adsorbing dust, bacteria, and odors, thereby improving the ambient air quality around the smart toilet and providing users with a fresher and healthier experience. Negative ions neutralize positive ions in the air, reducing static electricity and dryness, making the skin and respiratory tract more comfortable. During the drying process, the release of negative ions further enhances the user experience, especially in dry seasons or in environments with relatively polluted air. Negative ions have antibacterial and disinfecting effects, inhibiting the reproduction of bacteria and viruses and reducing hygiene hazards in the environment around the smart toilet. This design is particularly suitable for devices like smart toilets that come into direct contact with the human body, further improving hygiene levels.

[0043] In addition, such as Figure 1 As shown, this application also provides a smart toilet seat 10, which includes a core base 13, a flip cover, a seat ring 12, and a drying device 11 for a smart toilet as described in any of the above embodiments. The flip cover and the seat ring 12 are rotatably connected to the core base 13. The drying device is disposed on the core base 13, and the air outlet 132 of the drying device can be used to deliver air to the toilet bowl.
