Description

Technical Field

[0001] This invention relates to the field of nursing products, and in particular to a heated steam nasal humidifier. Background Technology

[0002] As the gateway to the human respiratory tract, the nasal cavity contains numerous mucous and serous glands in its mucous membrane, secreting approximately 1000 ml of fluid daily. 70% of this fluid is used to humidify inhaled air, while also performing physiological functions such as purification and temperature regulation, playing a vital role in protecting the lower respiratory tract and maintaining respiratory health. However, influenced by various factors, nasal dryness has become a common clinical symptom, manifesting as nasal dryness and discomfort, often accompanied by nasal itching, nasal congestion, nosebleeds, and decreased sense of smell. It is frequently seen in nasal diseases such as atrophic rhinitis and dry rhinitis, but can also be caused by non-disease factors such as dry environment, prolonged exposure to air conditioning, adverse drug reactions, and vitamin deficiencies. It severely impacts people's quality of life, and if persistent, may even induce more serious nasal lesions.

[0003] To alleviate nasal dryness, various nasal moisturizing products and solutions are currently available. These can be broadly categorized as follows: First, topical ointments or drops, such as peppermint oil, cod liver oil, and saline nasal drops. While these products can temporarily lubricate the nasal mucosa and relieve dryness, they can irritate the nasal cavity, and long-term use may affect the nasal mucosa's natural secretory function, failing to provide long-lasting humidification. Second, household humidifiers. These devices indirectly improve nasal dryness by increasing overall environmental humidity, but their humidification range is broad and lacks specificity, requiring prolonged operation to achieve the desired effect. Furthermore, humidifiers are limited by their location and are not portable. In addition, overall environmental humidification may provide a breeding ground for bacteria, posing a risk of secondary contamination, and is insufficient to meet the need for precise, localized nasal humidification.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-4As shown, a heated steam nasal humidifier includes a housing 1, a water tank assembly 2, a water absorption device 3, a heating and evaporation device 4, a fan assembly 5, an airflow guiding structure 6, a control unit 7, and an air outlet 8. The water tank assembly 2 is disposed inside the housing 1, with its water inlet exposed, for storing humidifying water. The water absorption device 3 is inserted into the water tank assembly 2, and the water in the water tank assembly 2 is absorbed and filled by the water absorption device 3. The water absorption device 3 is connected to the heating and evaporation device 4, which heats the surface of the water absorption device 3 to generate water vapor. The fan assembly 5 blows air towards the water vapor, propelling the water vapor and cooling it. By adjusting the fan assembly 5 and the airflow guiding structure 6, the water vapor temperature at the air outlet can be controlled at 35-38 degrees Celsius. The airflow guiding structure 6 guides the water vapor flow to the air outlet 8. The control unit 7 controls the operation of the heating and evaporation device 4 and the fan assembly 5. The cooled water vapor is discharged from the air outlet 8. This heated steam nasal humidifier integrates a water tank assembly 2, a water absorption device 3, a heating and evaporation device 4, a fan assembly 5, and an airflow guiding structure 6, achieving efficient, safe, and controllable steam generation and output. Water is absorbed by the water absorption device 3 and heated by the heating and evaporation device 4 to produce steam. The fan assembly 5 not only propels the steam flow but also moderately cools the high-temperature steam, making it more suitable for nasal inhalation. The airflow guiding structure 6 ensures stable steam delivery to the outlet 8, preventing leakage or condensation. The control unit 7 intelligently regulates heating and fan speed, comprehensively improving user comfort, safety, and energy efficiency.

[0019] The water absorption device 3 includes an absorbent sponge 9 and a porous, heat-resistant absorbent block 10. The heating and evaporation device 4 includes a heating element 11. The surfaces of the heat-resistant absorbent block 10 and the heating element 11 are attached together. Water is absorbed and fills the absorbent sponge 9. The water in the absorbent sponge 9 seeps into the heat-resistant absorbent block 10 through its pores. The heating element 10 heats the water that has seeped into the heat-resistant absorbent block 10. The heat-resistant absorbent block 10 is made of white corundum. This structure uses a combination design of absorbent sponge 9 and heat-resistant porous absorbent block 10, along with an attached heating element 11, to achieve a safe and efficient steam generation mechanism. The absorbent sponge 9 is responsible for quickly absorbing and storing the water in the water box 2, but because its material is not heat-resistant, it avoids direct contact with the heating element 11. The water seeps into the absorbent block 10 made of heat-resistant material below through the pores via capillary action, and is then directly heated and evaporated by the heating element 11, which is tightly attached to its surface. Because the absorbent block 10 has excellent heat resistance, it can withstand the high temperature of the heating element 11 for a long time without aging or deformation, thus ensuring the stability and reliability of the equipment during repeated use. This layered design not only protects the fragile sponge material 9, but also fully utilizes the advantages of the heat-resistant absorbent block 10 in high-temperature evaporation environments, significantly improving the overall safety, durability, and steam generation efficiency of the machine.

[0020] A spring 13 and a heating element holder 14 are arranged above the heating element 11. One end of the spring 13 abuts against the lower surface of the heating element holder 14, while the other end presses the heating element 11 towards the heating block 10 to reduce the gap and improve heat transfer efficiency. The spring 13 and heating element holder 14 above the heating element 11, through the elastic force of the spring 13, tightly press the heating element 11 against the heat-resistant absorbent block 10, effectively reducing the contact gap between them and significantly improving heat transfer efficiency. This structure ensures that heat is quickly and evenly transferred to the moisture in the heat-resistant absorbent block 10, reducing energy loss, improving steam generation efficiency, and enhancing the stability and lifespan of the equipment.

[0021] The absorbent sponge 9 includes a substrate 15 and an insert 16. The insert 16 is inserted into the heat-resistant absorbent block 10. Water first enters the substrate 15 and spreads to the insert 16 through capillary action. The water in the insert 16 enters the heat-resistant absorbent block 10 more quickly. The substrate 15 and the insert 16 form a convex cross-section structure. The absorbent sponge 9 uses a convex cross-section structure composed of the substrate 15 and the insert 16. The substrate 15 stores water and transports it to the insert 16 through capillary action. The insert 16 penetrates deep into the heat-resistant absorbent block 10, accelerating the transfer of moisture to the heating area. This structure optimizes the water transport path, shortens the time it takes for moisture to reach the evaporation zone, thereby improving the continuity and response speed of steam generation, while preventing the risk of dry burning due to insufficient water supply.

[0022] The water tank assembly 2 includes a water storage chamber 17 and a water level detector 18; both the water level detector 18 and the water suction device 3 are inserted into the water storage chamber 17. The integrated water level detector 18 in the water tank assembly 2 allows for real-time monitoring of the water level in the water storage chamber 17. When the water level is insufficient, the detector 18 promptly sends a signal to the control unit 7, automatically stopping heating to prevent dry burning and damage to the equipment or potential safety hazards. This design significantly improves the product's safety and intelligence, ensuring long-term stable use for users.

[0023] The water shortage detector 18 comprises two separate metal strips. These two separate metal strips form a detection circuit using the conductivity of water. When the water level is higher than the metal strips, the circuit is open, and the equipment operates normally; when the water level is too low, the circuit is closed, triggering a shutdown protection mechanism. This structure is simple, reliable, low-cost, and highly responsive, requiring no complex electronic components, effectively achieving automatic power-off functionality in case of water shortage.

[0024] The fan assembly 5 includes a fan 20, an air filter 21, a protective mesh 22, and an aromatherapy module 23. Outside air enters the fan 20 after passing through the aromatherapy module 23, the protective mesh 22, and the air filter 21. The fan assembly 5 integrates the aromatherapy module 23, the protective mesh 22, and the air filter 21, ensuring that the inhaled air undergoes aromatherapy, filtration, and protection before entering the fan 20. This not only releases a soothing fragrance to improve the user experience but also filters dust and impurities, enhancing the cleanliness of the inhaled air. Simultaneously, the protective mesh 22 prevents foreign objects from entering the fan 20, ensuring operational safety and achieving a multi-functional integration of humidification, purification, and aromatherapy.

[0025] The water tank assembly 2 also includes a water tank cover 24 and a water tank frame 25. The water tank cover 24 covers the water inlet 12. The water tank frame 25 includes a bottom cover 26 and a frame 27. The bottom cover 26 covers the top of the water tank assembly 2. The water suction device 3 passes through the water tank frame 25 and is inserted into the water storage chamber 17. The frame 27 has an air vent 28 on the side facing the fan assembly 5. The heating evaporation device 4 is located inside the frame 27. A steam gap is provided between the frame 27 and the heating evaporation device 4 to allow steam to pass through. The water tank assembly 2, through the water tank cover 24 and the water tank frame 25 (including the bottom cover 26 and the frame 27), forms a sealed and easy-to-maintain structure. The frame 27 has an air vent 28 and a steam gap, which allows airflow to carry steam while ensuring that an independent but connected steam channel is formed between the heating evaporation device 4 and the water tank 2, avoiding water-vapor short-circuiting or condensation backflow. This design optimizes the internal airflow organization, improves steam output efficiency, and facilitates disassembly, cleaning, and replacement of consumables.

[0026] The airflow guiding structure 6 is located above the heating and evaporating device 4; the air outlet 8 is a funnel-shaped opening; the airflow guiding structure 6 is connected to the air outlet 8. The airflow guiding structure 6, located above the heating and evaporating device 4 and connected to the funnel-shaped air outlet 8, can effectively converge and guide the steam flow to the outlet. The funnel-shaped air outlet 30 expands the outlet cross-section, reduces the airflow velocity, and allows for a gentler and more uniform release of steam, reducing irritation to the nasal cavity. It also prevents steam from condensing and dripping at the outlet, improving user comfort and hygiene.

[0027] The control unit 7 includes a control board 31, a front cover 32, a rear cover 33, and a control switch 34. The housing 1 also includes a battery 35 and a charging port 36. The control unit 7 is encapsulated with the control board 31 and the front and rear covers 32 and 33, and integrates the control switch 34. The housing 1 houses the battery 35 and the charging port 36, enabling portable power supply and operation of the device. This structure not only protects the control circuit 31 from moisture corrosion and improves reliability, but also supports wireless use and flexible charging, enhancing product mobility and user convenience, making it suitable for various scenarios such as home, office, or travel. The steam rack 37 is fitted onto the outside of the frame 27, featuring a compact structure and convenient assembly. It eliminates the need for additional independent airflow guiding components, simplifying the overall structure and reducing assembly costs. The air inlet 38 on the front side of the steam rack 37 faces the fan assembly 5, precisely receiving the airflow and water vapor blown out by the fan assembly 5, preventing airflow and steam diffusion and loss. The steam outlet 39 at the top is directly connected to the air outlet 8. Together with the airflow guiding structure 6 formed inside the steam rack 37, it achieves directional steam flow from the air inlet 38 to the air outlet 8, significantly reducing steam leakage, retention, and condensation inside the equipment, and improving steam utilization. At the same time, the steam rack 37 can provide a certain degree of heat preservation and buffering for the internal steam. Combined with the cooling effect of the fan assembly 5, it further stabilizes the steam temperature, preventing local temperatures from being too high or too low, and ensuring that the steam is gentle and suitable for nasal inhalation.
