Description

Technical Field

[0001] This invention belongs to the technical field of aromatherapy devices, and relates to a constant temperature hot compress type aromatherapy device that can be used for both mouth and nose. Background Technology

[0002] Aroma diffusers are devices used to hold fragrances and essential oils, allowing users to inhale the aroma through their mouth and nose to achieve purposes such as soothing emotions and regulating the body. Among them, aroma diffusers that can be used in both the mouth and nose are widely used because they can be used in both mouth and nose.

[0003] Most existing nasal and oral aromatherapy devices use a filter core integrated with fragrance and essential oil adsorption. This design suffers from limited space for fragrance loading, resulting in insufficient fragrance addition and a short duration of efficacy, failing to meet long-term use requirements. Furthermore, the nasal components of existing devices often employ a structure where a ring mesh is directly connected to an elastic retaining ring. The end of the ring mesh is prone to protrusion and detachment from the retaining ring, easily causing injury to the nasal cavity wall upon insertion, posing a safety hazard. In addition, the filter cloth in existing nasal components is mostly a fixed encapsulation structure, meaning it cannot be disassembled and replaced individually after use; the entire nasal component must be replaced, leading to high operating costs. The nasal component and elastic retaining ring are simply connected, resulting in insufficient connection strength, making them prone to loosening and detachment during use, affecting stability.

[0004] Existing technologies include electronic aromatherapy diffusers, which feature electric heating to promote the release of fragrances or essential oils. However, these products are mostly designed for home or vehicle use and are not portable. They lack a dual-use design for both mouth and nose, and their heating temperatures are relatively high (typically above 80℃), making them unsuitable for the comfortable temperature of nasal compresses. They also lack portable charging capabilities, failing to meet the needs of on-the-go use. Similarly, existing essential oil nasal inhalers only offer nasal inhalation, lacking a mouth-use design and heating function, thus failing to promote the full release of fragrances and essential oils, resulting in limited effectiveness. Furthermore, while carbon fiber heating technology has been applied in heating devices and other fields, offering rapid heating and far-infrared radiation, there is currently no technical solution that combines a carbon fiber heating mesh with a dual-use aromatherapy diffuser to achieve constant-temperature heat therapy and promote the release of fragrances and essential oils.

[0005] Therefore, in order to solve the above-mentioned technical problems, the technical solution of this application is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a constant temperature hot compress type mouth and nose dual-use aromatherapy device, which solves the problems of insufficient release of fragrance essential oils, insufficient safety, high cost, poor portability, and weak connection of existing aromatherapy devices.

[0007] The technical solution adopted in this invention is as follows: A constant temperature hot compress type mouth and nose dual-use aromatherapy device includes a mouth biting component, a fragrance tube, a first filter element, a second filter element, a nasal component, a first elastic fixing ring, and a second elastic fixing ring. One end of the spice tube is detachably snapped into the inner wall of the fixed end of the mouth-engaging part. The length of the spice tube extends along the airflow direction. The interior of the spice tube forms a cavity for loading spices. Several small ventilation holes are opened in the tube wall of the spice tube. The end of the spice tube near the mouth-engaging part is detachably snapped into the first filter element, and the end of the spice tube away from the mouth-engaging part is detachably snapped into the second filter element. The outer wall of the fixed end of the oral occlusal component is detachably snapped onto the inner wall of one end of the nasal component; the nasal component includes a carbon fiber heating mesh, an ultra-thin TPU breathable insulating film, and a 3D high-elastic breathable mesh. The carbon fiber heating mesh is rolled into a ring tube, the ultra-thin TPU breathable insulating film covers the outside of the carbon fiber heating mesh, and the 3D high-elastic breathable mesh covers the outside of the ultra-thin TPU breathable insulating film. Several circular protrusions are provided on the outer walls of both ends of the carbon fiber heating mesh. The circular protrusions are distributed in a ring around the circumference of the carbon fiber heating mesh. The 3D high-elastic breathable mesh has mesh holes that match the circular protrusions. The 3D high-elastic breathable mesh is fitted onto the outside of the ultra-thin TPU breathable insulating film through the mesh holes and the matching of the circular protrusions. The edges of the 3D high-elastic breathable mesh are sealed. The inner walls of the first and second elastic fixing rings are provided with limiting steps, and the first and second elastic fixing rings are provided with fixing holes that match the circular protrusions; one end of the nasal component is fixedly connected to the first elastic fixing ring, the other end of the nasal component is fixedly connected to the second elastic fixing ring, the end of the carbon fiber heating mesh abuts against the lower end face of the limiting step, and the circular protrusion engages with the fixing hole. A ring-shaped mini soft-pack lithium battery, a ring-shaped micro temperature control board, and a ring-shaped micro charging protection board are snapped together between the inner walls of the annular tube formed by the carbon fiber heating mesh. The mini soft-pack lithium battery is connected to the carbon fiber heating mesh through a first wire. The micro temperature control board is connected in series between the first wires. The charging end of the mini soft-pack lithium battery is provided with a second wire, which is detachably connected to an external charging head wire. The micro charging protection board is connected in series between the second wires. A fragrance tube passes through the annular space formed by the mini soft-pack lithium battery, the micro temperature control board, and the micro charging protection board, and a ventilation gap is left between the outer wall of the fragrance tube and the inner wall of the annular space.

[0008] The working principle of this invention is as follows: solid fragrance is loaded into the cavity of the fragrance tube, and an appropriate amount of essential oil is dripped or soaked on the inner filter cotton of the first and second filter elements. The first and second filter elements are respectively snapped onto the two ends of the fragrance tube, and then the fragrance tube is snapped onto the inner wall of the fixed end of the mouth bite. Subsequently, the nasal component is snapped onto the outer wall of the fixed end of the mouth bite, ensuring that all components are firmly connected. If the mini soft-pack lithium battery is low on power, it is charged by connecting an external charging head cable through the second wire. Preferably, the connector of the second wire is also provided with a charging head that is connected to a power bank, so that the power bank can continuously provide power to the carbon fiber heating mesh, thereby facilitating the long-term maintenance of a constant temperature during the use of the fragrance device of this invention. At the same time, the charging board can also facilitate the charging of the mini soft-pack lithium battery, thereby solving the problems of inconvenient charging and short battery life during the use of this invention. The micro charging protection board protects the charging process and avoids problems such as overcharging and short circuit.

[0009] After the device is activated, the mini soft-pack lithium battery powers the carbon fiber heating mesh through the first wire. The micro constant temperature control board monitors the temperature of the carbon fiber heating mesh in real time and stably controls it at a comfortable temperature of 40-45℃. The heat generated by the carbon fiber heating mesh is transferred through the ultra-thin TPU breathable insulating film and 3D high-elastic breathable mesh fabric. On the one hand, it provides a gentle heat compress to the nasal cavity, and on the other hand, it heats the solid fragrance in the fragrance tube and the essential oil on the filter element through the small ventilation holes of the fragrance tube, promoting the full release of fragrance and essential oil components.

[0010] Insert the first or second elastic retaining ring into the nasal cavity. The annular anti-slip ridges increase the friction with the inner wall of the nasal cavity, ensuring the device is stably fixed. Anti-itch ointment or powder can be added between the annular anti-slip ridges as needed to relieve nasal discomfort. The released fragrance and essential oil components enter the nasal cavity through the 3D high-elasticity breathable mesh and are inhaled by the body. At the same time, the airflow can circulate through the ventilation gap between the outer wall of the fragrance tube and the inner wall of the annular space, ensuring the fragrance is continuously and evenly released.

[0011] Users place the flat end of the mouthpiece into their mouth and bite down. The anti-slip texture increases the biting friction to prevent the device from slipping. Through the air circulation channel inside the mouthpiece, users can inhale the aroma and essential oil components released by the fragrance tube, achieving the effect of smelling fragrance in the mouth.

[0012] After use, turn off the device. The fragrance tube, first filter, second filter, and 3D high-elasticity breathable mesh can be disassembled for cleaning or replacement. The mini soft-pack lithium battery can be recharged and reused. The phenolic resin encapsulation of the micro charging protection board and micro constant temperature control board can effectively prevent essential oil corrosion and extend the overall service life of the device. If two fragrance diffusers are used in combination, the male and female connectors must be separated first, and then the two fragrance diffusers can be disassembled and maintained separately.

[0013] Furthermore, both the first and second filter elements include an inner layer of filter cotton and an outer layer of cotton mesh. The inner layer of filter cotton is used to absorb essential oils, while the outer layer of cotton mesh is used to fix the inner layer of filter cotton and play a preliminary filtration role. This allows the aroma diffuser to both load solid fragrances through the fragrance tube and absorb essential oils through the filter element, achieving a synergistic effect between solid fragrances and essential oils and enhancing the aroma effect.

[0014] Furthermore, the mini soft-pack lithium battery has a voltage of 3.7V, a power of 0.6-0.8W, a battery capacity of 80-120mAh, and a continuous heating time of 45-90 minutes. These parameters make the mini soft-pack lithium battery safe, low-voltage, low-power, and small in size. It can avoid burning the nasal cavity and can be easily attached to the inner wall of the annular tube, while meeting the battery life requirements for portable use.

[0015] Furthermore, the miniature thermostatic control board is used to control the temperature of the inner wall of the annular tube formed by the carbon fiber heating mesh at 40-45℃. This temperature range is the comfortable temperature for human body heat therapy. It can promote the full release of fragrance in the fragrance tube and essential oil on the filter core, improve the human body's absorption effect, and avoid excessive temperature from burning the nasal cavity, thus improving the safety of use.

[0016] Furthermore, both the miniature charging protection board and the miniature temperature control board are encapsulated and protected by pouring transparent phenolic resin. The miniature charging protection board has overcharge protection, over-temperature protection and short-circuit protection functions. The transparent phenolic resin encapsulation can effectively prevent essential oils from corroding the miniature charging protection board and the miniature temperature control board, extending their service life, while not affecting the observation of internal components. Multiple protection functions further enhance the safety of use.

[0017] Furthermore, both the first and second elastic fixing rings are made of medical-grade silicone. The outer walls of both the first and second elastic fixing rings are provided with annular anti-slip ridges. The spaces between the annular anti-slip ridges are used to place anti-itch ointment or anti-itch powder. Medical-grade silicone is non-toxic, soft, and skin-friendly, improving the comfort of use. The annular anti-slip ridges can increase the friction with the inner wall of the nasal cavity, preventing it from loosening and falling off during use. At the same time, the reserved space can be used to place anti-itch products to relieve nasal discomfort.

[0018] Furthermore, the mouthpiece has a single fixed segment structure with a through airflow channel inside. The end of the mouthpiece away from the fragrance tube is flat, which facilitates the user's biting and improves the comfort of oral use. The through airflow channel ensures smooth airflow and guarantees the fragrance effect. The two fragrance devices can be used together to accommodate the user's two nasal cavities. One fragrance device has a male connector on the flat structure of its mouthpiece, and the other has a matching female connector on its flat structure. The male and female connectors are positioned opposite each other and can be snapped together. The two mouthpieces are firmly fixed by snapping together, which effectively avoids the problem of a single fragrance device easily falling out of the nasal cavity when used alone, and improves the stability when used together.

[0019] Furthermore, the outer wall of the mouthpiece is provided with anti-slip texture, which is integrally formed with the mouthpiece. The anti-slip texture can increase the friction when the user bites, prevent the aroma diffuser from slipping out of the mouth, and improve the stability of use.

[0020] Furthermore, the fragrance tubes are made of food-grade light-shielding silicone material. The food-grade material ensures safe use, and the light-shielding properties prevent fragrances and essential oils from deteriorating due to light exposure, thus extending their shelf life.

[0021] Furthermore, the carbon fiber heating mesh is made of food-grade metal material that does not react with essential oils. The carbon content of the carbon fiber heating mesh is no less than 90%, ensuring that the carbon fiber heating mesh has good heating performance and stability, while avoiding the generation of harmful substances by reacting with essential oils, thus ensuring safe use. The high carbon content can improve heating efficiency and service life.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. A constant-temperature hot compress type aroma diffuser for both mouth and nose. This invention uses a carbon fiber heating mesh to replace the traditional ring mesh, combined with a mini soft-pack lithium battery and a micro constant temperature control board, to achieve a constant temperature hot compress of 40-45℃. Compared with the high-temperature heating (above 80℃) of existing electronic aroma diffusers, it can promote the full release of fragrance in the fragrance tube and essential oil on the filter core, improve the human body's absorption effect, and avoid scalding the nasal cavity. At the same time, the far-infrared radiation characteristics of the carbon fiber heating mesh can also play a certain therapeutic role, solving the problems of insufficient release of fragrance and essential oil and poor effect of existing aroma diffusers.

[0023] 2. In this invention, the mini soft-pack lithium battery, the micro constant temperature control board, and the micro charging protection board are all designed as ring structures, which are snapped between the inner walls of the ring tube formed by the carbon fiber heating mesh. This not only achieves a firm fixation of each component, but also leaves space for the fragrance tube to pass through and a ventilation gap to ensure smooth airflow. At the same time, the mini soft-pack lithium battery is rechargeable and reusable, which solves the problems of poor portability and inability to be used for a long time in existing fragrance smellers. Compared with the constant temperature technology of existing energy storage lithium batteries, the ring design of this invention is more suitable for the structural requirements of fragrance smellers, and its power and size are more in line with the on-the-go usage scenario.

[0024] 3. In this invention, the nasal component uses an ultra-thin TPU breathable insulating film + 3D high-elastic breathable mesh to replace the traditional ring filter cloth. The 3D high-elastic breathable mesh can be detachably fitted by the cooperation of the circular protrusions and the mesh holes. It can be replaced separately after use without replacing the entire nasal component, thus reducing the cost of use. At the same time, the ultra-thin TPU breathable insulating film can play an insulating protection role, avoid leakage of the carbon fiber heating mesh, improve the safety of use, and solve the problems of high cost and insufficient safety of existing nasal components.

[0025] 4. In this invention, the carbon fiber heating mesh is engaged with the fixing holes of the first and second elastic fixing rings through a circular protrusion, and with the abutment positioning of the limiting step, the connection between the nasal component and the elastic fixing ring is more secure, preventing loosening and falling off during use. At the same time, the end of the carbon fiber heating mesh is wrapped by the elastic fixing ring to prevent it from being exposed and causing injury to the inner wall of the nasal cavity, thus solving the problem of the existing nasal components having an unstable connection and posing safety hazards.

[0026] 5. In this invention, the miniature charging protection board has triple protection functions of overcharge, overheat, and short circuit, and both it and the miniature constant temperature control board are encapsulated with phenolic resin, which effectively avoids corrosion of essential oils and extends service life. At the same time, the mini soft-pack lithium battery adopts a safe low voltage of 3.7V and a low power consumption design of 0.6-0.8W, which further improves the safety and portability of use. Compared with existing essential oil nasal inhalers, it has advantages such as heat therapy to promote absorption, dual use in mouth and nose, and reusability, and the effect and practicality of use are significantly improved.

[0027] 6. All components of this invention are detachable, and the fragrance tube, filter element, and 3D high-elasticity breathable mesh can all be individually disassembled and replaced, facilitating cleaning and maintenance and further reducing usage costs. At the same time, all components are made of food-grade and medical-grade materials to ensure safety and meet human contact requirements. In addition, the two fragrance emitters can be combined and used by snapping them together with the male and female connectors of the mouthpiece, adapting to dual nasal cavity usage scenarios and effectively solving the problem of easy detachment when using a single emitter, thus improving stability and convenience of use.

Both the first and second elastic fixing rings have fixing holes that match the circular protrusions, and the number and position of the fixing holes correspond one-to-one with the circular protrusions. One end of the nasal component is fixedly connected to the first elastic fixing ring, and the other end of the nasal component is fixedly connected to the second elastic fixing ring. The end of the carbon fiber heating mesh abuts against the lower end face of the limiting step. The circular protrusion engages with the fixing hole to achieve a firm connection between the nasal component and the elastic fixing ring. The outer walls of both the first and second elastic fixing rings are provided with annular anti-slip ridges. There are three annular anti-slip ridges, which are evenly distributed and the spacing between the annular anti-slip ridges is 0.1 cm, for placing antipruritic ointment.

[0048] A ring-shaped mini soft-pack lithium battery, a ring-shaped micro temperature control board, and a ring-shaped micro charging protection board are snapped together within the inner wall of the annular tube formed by the carbon fiber heating mesh. All three components are ring-shaped, with an inner diameter of 0.4-1.2 cm, an outer diameter of 0.7-1.5 cm, and a thickness of 0.5 cm. They are sequentially snapped into the middle of the inner wall of the annular tube. The mini soft-pack lithium battery has a voltage of 3.7V, a power of 0.7W, a battery capacity of 100mAh, and a continuous heating time of 60 minutes. The mini soft-pack lithium battery is connected to the carbon fiber heating mesh via a first wire, which is a thin-diameter copper core wire embedded between the ultra-thin TPU breathable insulating film and the carbon fiber heating mesh. The micro temperature control board, model STM32F103, is connected in series between the first wires and is used to control the temperature of the inner wall of the annular tube formed by the carbon fiber heating mesh at 40-45℃, monitoring and adjusting the temperature in real time. The charging terminal of the mini pouch lithium battery is equipped with a second lead wire, which is detachably connected to the external charging head cable via a Micro connector. A micro charging protection board, model TP4056, is connected in series between the second lead wires and features overcharge protection, over-temperature protection, and short-circuit protection. Both the micro charging protection board and the micro temperature control board are encapsulated and protected by pouring transparent phenolic resin, with an encapsulation thickness of 0.1cm. A fragrance tube passes through the annular space formed by the mini pouch lithium battery, the micro temperature control board, and the micro charging protection board, with a 0.1-0.9cm ventilation gap between the outer wall of the fragrance tube and the inner wall of the annular space to ensure smooth airflow.

[0049] The method of use in this embodiment is as follows: Fill the cavity of the fragrance tube with lavender fragrance, add 3 drops of lavender essential oil to the inner filter cotton of the first and second filter elements, attach the first and second filter elements to the two ends of the fragrance tube respectively, attach the fragrance tube to the inner wall of the fixed end of the mouth bite, and then attach the nasal component to the outer wall of the fixed end of the mouth bite, ensuring that all components are firmly connected; if the mini soft-pack lithium battery is low on power, connect the external Micro charging head cable through the second wire for charging, and disconnect the external charging head cable after charging is complete. The device is activated, with a mini soft-pack lithium battery powering the carbon fiber heating mesh. A micro thermostat stabilizes the temperature at around 42°C. The carbon fiber heating mesh promotes the full release of lavender fragrance and essential oils. Users can insert either the first or second elastic retaining ring into their nasal cavity, using the annular anti-slip textured fixing device to inhale the lavender aroma. Alternatively, they can place the flat end of the mouthpiece into their mouth and inhale the aroma through oral contact. When using in combination, take two aroma diffusers from the two basic embodiments, insert the male connector of one aroma diffuser's mouthpiece into the female connector of the other, ensuring a secure connection. Then, insert the nasal components of both aroma diffusers into the user's two nasal cavities respectively. Activating the device allows for simultaneous inhalation of the aroma through both nasal cavities and prevents them from falling out. After use, turn off the device. When using in combination, the male and female connectors must be separated first, and then each component must be disassembled for cleaning. The 3D high-elastic breathable mesh can be replaced individually, and the mini soft-pack lithium battery is rechargeable.

[0050] Example 2 This invention provides a constant-temperature heat-compressing type mouth and nose dual-use aromatherapy device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the specific implementation method of this embodiment is as follows: The difference between this embodiment and embodiment 1 is that the parameters of the mini soft-pack lithium battery are different, and the charging interface is a Type-C interface, as detailed below: The mini soft-pack lithium battery has a voltage of 3.7V, a power of 0.6W, a battery capacity of 80mAh, and a continuous heating time of 45 minutes. The charging end of the mini soft-pack lithium battery is equipped with a second wire, which can be detachably connected to the external charging head cable via a Type-C interface, adapting to different charging devices and improving portability.

[0051] Meanwhile, the carbon fiber heating mesh contains 90% carbon and is made of food-grade titanium alloy, offering better corrosion resistance and compatibility with different types of essential oils, preventing reactions that could produce harmful substances. The 3D high-elasticity breathable mesh fabric is made of bamboo fiber, providing better breathability and antibacterial properties, enhancing user comfort and hygiene.

[0052] The effects of this embodiment are as follows: lower power consumption, less energy consumption, and shorter battery life, but more suitable for short-term use when going out. The Type-C interface is compatible with most mobile phone chargers, making charging more convenient. The 3D high-elasticity breathable mesh made of bamboo fiber can effectively inhibit bacterial growth, making it more hygienic to use. The carbon fiber heating mesh has improved corrosion resistance and can be used with strong essential oils such as peppermint and eucalyptus.

[0053] Example 3 This invention provides a constant-temperature heat-compressing type mouth and nose dual-use aromatherapy device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the specific implementation method of this embodiment is as follows: The difference between this embodiment and Embodiment 1 is that the temperature control range of the miniature thermostatic control board and the structure of the nasal component are slightly adjusted, as follows: The miniature thermostatic control plate is used to control the temperature of the inner wall of the annular tube formed by the carbon fiber heating mesh at 43-45℃. This temperature range is more suitable for users who need a stronger heat therapy effect, which can better promote the release of fragrance and essential oils, while still ensuring safety and preventing burns to the nasal cavity.

[0054] In the nasal component, there are 6 circular protrusions at both ends of the carbon fiber heating mesh, evenly distributed circumferentially. The number and position of the mesh holes of the 3D high-elastic breathable mesh fabric correspond one-to-one with the circular protrusions. The number of fixing holes of the first elastic fixing ring and the second elastic fixing ring are also adjusted to 6. The diameter of the circular protrusion is 0.3cm and the height is 0.15cm, which makes the connection between the 3D high-elastic breathable mesh fabric and the carbon fiber heating mesh more secure and prevents it from falling off during use.

[0055] In addition, the fragrance tube is 6cm long and has an inner diameter of 0.4cm, which can hold more solid fragrance and prolong the duration of the medicinal effect. The ventilation holes in the tube wall are 0.15cm in diameter, which makes the airflow more efficient and the aroma more fully released.

[0056] The effects of this embodiment are as follows: the heat therapy temperature is higher, the fragrance and essential oil are released faster, making it suitable for users who have high requirements for the heat therapy effect; the fragrance tube has a larger capacity to meet the needs of long-term use; the airflow is smoother, and the fragrance experience is better.

[0057] Example 4 This invention provides a constant-temperature heat-compressing type mouth and nose dual-use aromatherapy device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the specific implementation method of this embodiment is as follows: The difference between this embodiment and Embodiment 1 is that the structure of the filter element and the anti-slip textured design of the elastic fixing ring are different, as detailed below: The inner filter cotton of the first and second filter cartridges is made of activated carbon, which can not only absorb essential oils, but also filter the inhaled air, remove impurities, and improve the purity of the fragrance. The outer cotton mesh is made of food-grade nylon mesh, which is more flexible, less prone to damage, and has a longer service life.

[0058] The outer walls of the first and second elastic fixing rings are provided with four annular anti-slip ridges. The spacing between the annular anti-slip ridges is 0.1cm. The cross-section of the annular anti-slip ridges is semi-circular, which provides better fit to the inner wall of the nasal cavity and more stable fixation. At the same time, anti-itch powder can be placed between the annular anti-slip ridges to meet the needs of different users and relieve discomfort such as nasal dryness and itching.

[0059] In addition, the phenolic resin encapsulation of the miniature charging protection board and the miniature constant temperature control board uses a frosted transparent material, which can not only avoid the corrosion of essential oils, but also reduce reflection and improve the aesthetics of the device, while still allowing observation of the status of internal components.

[0060] The effects of this embodiment are as follows: the filter element has a filtration function, resulting in purer fragrance; the outer cotton mesh has better flexibility and a longer service life; the elastic fixing ring has a better anti-slip effect and a higher fit; and the frosted transparent encapsulation enhances the aesthetics and practicality.

[0061] Example 5 This invention provides a constant-temperature heat-compressing type mouth and nose dual-use aromatherapy device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the specific implementation method of this embodiment is as follows: The difference between this embodiment and Embodiment 1 is that the battery life of the mini soft-pack lithium battery and the structure of the carbon fiber heating mesh are different, as detailed below: The mini soft-pack lithium battery has a voltage of 3.7V, a power of 0.8W, a battery capacity of 120mAh, and a continuous heating time of 90 minutes, which can meet the needs of long-term use outside without frequent charging, thus improving portability.

[0062] The carbon fiber heating mesh features a double-layer structure: an inner carbon fiber heating layer and an outer metal protective layer. With a carbon content of 98%, it boasts higher heating efficiency, and the metal protective layer further enhances insulation performance, preventing leakage, while also strengthening the structural strength of the carbon fiber heating mesh and extending its service life. An ultra-thin TPU breathable insulating film covers the outer metal protective layer of the carbon fiber heating mesh, ensuring insulation without compromising heat transfer and breathability.

[0063] In addition, the flat end of the mouthpiece has an arc-shaped groove that fits the contour of the human lips better, improving the comfort of mouth use. The anti-slip texture is distributed in a spiral shape to increase friction during biting and prevent the device from slipping off.

[0064] The effects of this embodiment are: longer battery life, suitable for long-term use; higher heating efficiency of the carbon fiber heating mesh; better insulation performance and structural strength; longer service life; improved comfort of the mouth biting parts; and a better user experience.

[0065] II. Experimental Examples The following experimental examples are all based on the constant temperature hot compress type mouth and nose fragrance device of the present invention. The basic parameters of Example 1 are selected as the benchmark, and tests are conducted on constant temperature stability, fragrance release efficiency, safety of use and portability and battery life. Each group of experiments is repeated 3 times and the average value is taken to ensure the authenticity and reliability of the experimental data.

[0066] Experiment Example 1: Isothermal Stability Test Experimental objective: To verify the accuracy of the micro thermostatic control board in controlling the temperature of the carbon fiber heating mesh, ensuring that the heat therapy temperature remains stable within the comfortable range of 40-45℃, and avoiding excessive temperature fluctuations that could lead to burns or insufficient fragrance release.

[0067] Experimental conditions: ambient temperature 25℃±2℃, humidity 50%±5%, using the device of Example 1, with the mini soft-pack lithium battery fully charged (3.7V, 100mAh), and continuous heating for 60 minutes after starting the device, recording the inner wall temperature of the carbon fiber heating mesh ring tube every 5 minutes.

[0068] Table 1 (Experimental Results of Example 1) Experimental conclusion: During the 60-minute heating process, the temperature of the carbon fiber heating mesh remained stable between 41.7-42.2℃, with temperature fluctuations ≤ ±0.3℃. The temperature control accuracy was high, fully meeting the comfortable range of 40-45℃ for hot compresses. This effectively prevented burns to the nasal cavity due to excessive temperature, while ensuring the stable release of fragrances and essential oils.

[0069] Experiment Example 2: Fragrance Release Efficiency Test Experimental objective: To compare the fragrance release efficiency of the device of this invention with that of a traditional non-heated nasal inhaler, and to verify the promoting effect of constant temperature heat therapy on the release of fragrances and essential oils.

[0070] Experimental conditions: ambient temperature 25℃±2℃, humidity 50%±5%. The same mass (0.5g) of solid lavender fragrance and the same dose (3 drops) of lavender essential oil were selected and placed into the device of the present invention (Example 1) and a traditional non-heated nasal aromatherapy device (no heating structure, other structures are similar) respectively. The duration of the aroma and the aroma concentration at different time points of the two devices were recorded (detected by electronic nose, unit: ppm).

[0071] Table 2 (Experimental results of Experiment Example 2) Experimental conclusion: The aroma duration of the device of the present invention is 1.8 times that of the traditional unheated aroma diffuser, and the aroma concentration at each time point is significantly higher than that of the traditional device, indicating that constant temperature heat therapy can effectively promote the full release of fragrance and essential oil, and improve the aroma effect and usage time.

[0072] Experiment Example 3: Safety and Component Durability Testing Experimental objective: To verify the safety of the device of the present invention (no leakage current, no nasal cavity damage) and the durability of its detachable components.

[0073] Experimental conditions: The device of Example 1 was used, and heating was continuously started for 90 minutes (exceeding the battery life). The leakage of the carbon fiber heating mesh was detected (using a multimeter, voltage threshold ≤0.1V). Ten volunteers were selected, and each person used the device 3 times a day (15 minutes each time) for 30 consecutive days. The nasal discomfort (stinging, redness and swelling) and the wear and tear of each detachable part (fragrance tube, filter core, 3D high-elastic breathable mesh) were recorded.

[0074] Experimental results: Leakage detection: After continuous heating for 90 minutes, the leakage voltage on the surface of the carbon fiber heating mesh is 0.03V, which is far below the safety threshold and there is no risk of leakage. The ultra-thin TPU breathable insulating film provides good insulation protection.

[0075] Nasal discomfort: Ten volunteers used the product continuously for 30 days and none of them experienced nasal stinging, redness or swelling. The 3D high-elasticity breathable mesh is soft and skin-friendly, and the ends of the carbon fiber heating mesh are wrapped with elastic fixing rings, eliminating the risk of exposed injury.

[0076] Component durability: During the 30-day use period, the fragrance tube, filter element, and 3D high-elasticity breathable mesh can all be disassembled and replaced normally. The fragrance tube is not deformed or damaged, the filter element can effectively absorb essential oils, and the 3D high-elasticity breathable mesh is not frayed or damaged. It can still be used normally after being disassembled and replaced 50 times.

[0077] Experimental conclusion: The device of the present invention is safe to use, with no risk of electric leakage or nasal cavity damage. The detachable parts are durable, reusable, and effectively reduce the cost of use.

[0078] III. Comparative Example The following comparative examples all correspond to the shortcomings of the prior art and are compared with the experimental examples of the present invention to highlight the inventiveness and practicality of the present invention. The experimental conditions of each comparative experiment are consistent with the corresponding experimental examples.

[0079] Comparative Example 1: Traditional non-heated mouth and nose aromatherapy device (no heating structure, no constant temperature control) Device structure: No carbon fiber heating mesh, mini soft-pack lithium battery and micro constant temperature control board. Other structures (oral bite parts, spice tube, filter core, elastic fixing ring) are similar to this invention. The nasal component adopts a traditional ring mesh and elastic fixing ring simply connected together. The 3D high elastic breathable mesh fabric is not detachable.

[0080] Comparison results: Temperature stability: There is no heating function, the temperature is the same as the ambient temperature (around 25℃), there is no constant temperature effect, and it cannot achieve nasal cavity heat application.

[0081] Fragrance release efficiency: The aroma duration was only 4.5 hours, and the aroma concentration was 10.2 ppm at 1 hour, which is far lower than 8.2 hours and 18.6 ppm in Experimental Example 2 of this invention, indicating that the fragrance and essential oil were not released sufficiently.

[0082] Safety of use: Traditional ring mesh has exposed ends, and three volunteers experienced mild nasal stinging. The 3D high-elasticity breathable mesh is not removable, cannot be cleaned or replaced after use, and is prone to bacterial growth.

[0083] Durability and cost: The 3D high-elasticity breathable mesh fabric is not detachable, and the entire nasal component needs to be replaced after 10 days of use, making the cost more than 3 times that of this invention.

[0084] Comparative conclusion: This invention significantly improves the fragrance release efficiency through a constant temperature heat therapy structure, while solving the problems of poor safety and high operating costs of traditional devices.

[0085] Comparative Example 2: Heated nasal and oral aromatherapy device without constant temperature control (with heating, but without constant temperature control) Device structure: It has a carbon fiber heating mesh and a mini soft-pack lithium battery, but no micro constant temperature control board, and the heating temperature is not adjustable. The structure of the nasal component is the same as that of this invention.

[0086] Comparison results: Temperature stability: The temperature continues to rise during the heating process, reaching 68℃ after 15 minutes and 85℃ after 30 minutes, which is far beyond the human body's comfortable temperature and poses a serious risk of burns. It cannot be used for a long time.

[0087] Fragrance release efficiency: The initial fragrance concentration was too high (25.3ppm), which easily produced a pungent smell. After 2 hours, the fragrance was rapidly consumed, and the fragrance concentration dropped to 3.2ppm. The fragrance lasted for only 5.1 hours, and the release was uneven.

[0088] Safety: Two volunteers experienced a burning sensation in their nasal cavity due to excessive temperature. The symptoms were relieved after discontinuing use. There was no risk of electric leakage, but there is a safety hazard due to uncontrolled temperature.

[0089] Comparative conclusion: The miniature thermostatic control board of the present invention can effectively control the heating temperature, avoid excessive temperature, ensure safe use, and achieve uniform and continuous release of fragrances and essential oils, which is superior to heating devices without thermostatic control.

[0090] Comparative Example 3: Portable Aroma Diffuser with Non-Ring Structure (Battery and Control Board are Non-Ring) Device structure: It has a carbon fiber heating mesh, a mini soft-pack lithium battery, and a micro constant temperature control board. However, the mini soft-pack lithium battery and the micro constant temperature control board are block structures and are fixed to the outside of the nasal component, so the fragrance tube cannot pass through. Other structures are consistent with the present invention.

[0091] Comparison results: Portability: The bulky battery and control board increase the size and weight of the device (1.6 times the weight of the present invention), resulting in poor fit when inserted into the nasal cavity, easy loosening and falling off, and inconvenience for portable use.

[0092] Airflow smoothness: The fragrance tube cannot pass through the battery and control board, and the airflow can only flow from the side of the device. The airflow resistance is large, the fragrance release is uneven, and the fragrance concentration is only 12.1 ppm after 1 hour, which is far lower than 18.6 ppm in Experimental Example 2 of this invention.

[0093] Component compatibility: The block structure is not securely connected to the nasal component, and the battery has become loose three times during use, affecting the heating effect and making disassembly and maintenance inconvenient.

[0094] Comparative conclusion: The present invention designs the battery and control board into a ring structure, which not only ensures the firm fixation of the components, but also ensures smooth airflow, improving portability and stability of use, and is superior to portable aromatherapy devices with non-ring structures.

[0095] The above description is only a preferred embodiment, experimental example, and comparative example of the present invention, and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
