Description

Technical Field

[0001] This invention belongs to the field of air purification technology, and more specifically, relates to an air purification device for high humidity environments with stable fragrance diffusion. Background Technology

[0002] An air purifier is a device that operates based on the linkage of mechanical structures and the principle of physical purification. It typically integrates filter components, activated carbon adsorption layers, air duct systems, and fan modules. The fan drives air to flow through these functional structures, which can efficiently capture suspended particulate matter such as PM2.5, adsorb harmful gases such as formaldehyde, remove odors and some microorganisms. It can achieve air circulation and purification without the need for a complex electronic control system. It is widely used in homes, offices, industrial workshops and other scenarios, and can quickly improve air quality and create a healthy breathing environment for users.

[0003] Current air purification devices have been found to have at least the following problems:

[0004] First, air purifiers, as commonly used indoor air treatment devices, are widely used in various scenarios such as homes, offices, and enclosed spaces. Some of these environments have high humidity levels, such as the rainy season in southern China, humid coastal areas, and environments with large temperature differences in air-conditioned rooms. In these humid working environments, moisture in the air easily condenses on the surface of the filter material during the air filtration process, forming condensate. At the same time, a small amount of dust may fall off the filter after long-term use. The internal structure of existing air purifiers lacks a dedicated structure for guiding and collecting this condensate and dust, causing condensate and dust to accumulate inside the device. This can provide a breeding ground for bacteria and may also contaminate internal core components such as motor components and the lower casing. This not only affects the cleanliness of the device's interior but also increases the risk of malfunctions caused by component contamination, thus affecting the stable operation and lifespan of the device.

[0005] Secondly, with the improvement of living standards, the application scenarios of air purifiers have expanded to diversified spaces such as home decoration, office atmosphere creation, and entertainment scene enhancement. While focusing on its core air purification function, users have also raised higher requirements for the product's appearance coordination, visual experience, and decorative properties. Some existing air purifiers with lighting or ambient lighting functions often use exposed installation designs for their light strips or lack corresponding light optimization structures, resulting in glare and uneven light distribution. In addition, the color and dynamic effects of the light strips are relatively limited. In scenarios such as home decoration and office environment layout, this type of design makes it difficult for air purifiers to match the style of the surrounding space. They can only exist as simple functional home appliances and cannot be integrated into the space decoration system. They cannot meet users' needs for enhancing the style of the space, nor can they fully take into account the dual demands of product practicality and aesthetics. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an air purification device for high-humidity environments with stable and effective fragrance diffusion. This addresses the issue that air purifiers are widely used in homes, offices, and other settings where humidity is high, such as during the rainy season in southern China or in humid coastal areas. In these environments, the internal filters easily condense liquid when filtering air, and a small amount of dust may fall off after prolonged use. Existing air purifiers lack specific structures for guiding and collecting this condensate and dust, leading to their accumulation inside the device. This accumulation can potentially breed bacteria, contaminate core components such as motors, and affect the cleanliness, stable operation, and lifespan of the device.

[0007] An air purification device for high-humidity environments with stable and effective fragrance diffusion includes an electronic control component, an air outlet mesh, a motor component, an upper shell component, a fragrance box, a dust sensor, a light cover, a light guide ring, a light strip, a light shielding ring, a lower shell, a filter, a bottom cover, a liquid collection tank, an overflow hole, a vaporization ring, and slow-release fibers. The detachable connection between the fragrance box and the vaporization ring, the liquid collection tank and the overflow hole, and the concealed light strip, light guide ring, and light shielding ring serve as the core functional components. The fragrance box and the vaporization ring are snap-fitted together to form a fragrance release unit. The upper shell component and the lower shell are assembled into the main body of the device via a fixing mechanism, and the filter is adapted to the lower shell. The installation process integrates the motor assembly within the upper housing. The light guide ring and light shielding ring work together to wrap around the LED strip. The liquid collection tank is positioned at the bottom of the filter, and the overflow hole is located on the side wall of the liquid collection tank. Slow-release fibers are filled in the evaporation groove of the evaporation ring. The detachable assembly allows for convenient replenishment of the fragrance. The liquid collection tank and overflow hole drain condensate. The LED strip, light guide ring, and light shielding ring optimize light efficiency. This design solves problems such as uneven fragrance evaporation, water and dust accumulation, sealing leaks, lack of synergy between light and fragrance, and high cost and difficulty in matching additional parts in traditional air purifiers. It improves the device's functional integration, user comfort, structural stability, and service life.

[0008] Preferably, the evaporation ring is made of ABS material, with a modified formula to optimize the buckle's toughness. The material possesses excellent structural strength and corrosion resistance. The modified formula enhances the stability of the buckle's fit with the aromatherapy box, preventing damage to the buckle caused by long-term disassembly and assembly, ensuring the long-term reliability of the aroma release unit. It is suitable for various usage scenarios such as home and office, balancing practicality and durability. The fixing mechanism adopts a combination of snap-fit ​​and quick-twist lock structure, evenly distributed circumferentially along the mating surface between the upper and lower shell components. The combination structure enables quick assembly and secure fixing of the main body of the device, avoiding loosening caused by a single connection method. It meets the needs of production assembly efficiency and convenient daily maintenance, improves the overall structural stability, and extends the service life of the device.

[0009] Preferably, the slow-release fibers are arranged in an array-type filling structure, which is evenly distributed throughout the annular evaporation groove of the evaporation ring. The array-type layout can maximize the aroma adsorption area and take into account the adsorption capacity and evaporation rate with a reasonable filling method, so as to avoid excessive or insufficient release of aroma, achieve uniform slow release of fragrance, and allow users to experience a continuously comfortable aroma environment.

[0010] Preferably, the liquid collection tank adopts an annular groove structure, which is precisely matched with the bottom contour of the filter. The annular groove can realize the full-area collection of condensate and dust. The depth and width of the tank are adapted to the liquid storage needs, preventing overflow of small amounts of liquid. The tank wall has an inclined structure to guide the liquid to the overflow hole, improving drainage efficiency and reducing the risk of internal component contamination. The filter and the lower shell base are equipped with an annular sealing groove, and a silicone sealing ring is installed in the groove. The sealing groove and the bottom boss of the filter fit precisely. The elastic deformation of the silicone sealing ring can eliminate the assembly gap, prevent unfiltered air leakage, improve purification efficiency, and at the same time buffer the vibration of the equipment during operation, providing effective protection for the filter.

[0011] Preferably, the light guide ring and the light shielding ring adopt an integrated nested structure. The nested structure can optimize the light propagation path and avoid glare. The light-transmitting and light-shielding materials are zoned and coordinated to ensure soft and uniform lighting, enhance the effect of creating an ambient atmosphere, and make the device have both lighting function and decorative value. The light strip uses low-power LED beads, which are evenly arranged in a ring array inside the light shielding ring. The low power consumption characteristic reduces the energy consumption of the device. The ring array ensures full coverage of the light and the brightness of the beads remains consistent, avoiding uneven local light and dark areas. It is compatible with various color adjustment needs and meets the atmosphere creation of different scenarios.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a liquid collection tank and an overflow hole are provided. The liquid collection tank corresponds to the bottom of the filter. Condensate or small amounts of dust generated by the filter in a humid environment can flow into the liquid collection tank through the structural design, preventing water from accumulating inside the equipment and breeding bacteria, contaminating the motor components or the interior of the lower casing. At the same time, the overflow hole can discharge excess liquid in time, preventing secondary pollution caused by liquid overflow. This structure effectively protects the internal components of the equipment, reduces the risk of failure caused by water and dust accumulation, and extends the service life of the equipment. In addition, the design of the liquid collection tank and the bottom cover makes it convenient for users to clean regularly, reduces maintenance difficulty, and ensures that the equipment maintains a clean operating state for a long time, taking into account both practicality and ease of maintenance.

[0014] In this invention, a concealed light strip, light guide ring, and light shielding ring are integrated seamlessly with the purifier's outer shell, preventing exposure and affecting aesthetics. The light guide ring and light shielding ring work together to optimize the light propagation path, resulting in soft, uniform, and glare-free light. The light strip supports multiple color adjustments and dynamic effect switching, allowing for flexible adjustments based on home style, usage scenario, and user mood. It adapts to different needs such as home decoration, creating an office atmosphere, and enhancing entertainment scenarios, transforming the air purifier from a simple functional appliance into a part of home decoration that enhances the style of the space. This enriches the visual experience of the environment and enhances the product's aesthetics and decorative appeal.

[0015] In this invention, an aromatherapy box, a detachable evaporation ring, and slow-release fibers in an evaporation tank are incorporated. The aromatherapy box features a press-button snap structure for easy addition of aromatherapy medium. The bottom of the evaporation ring is higher than the bottom of the aromatherapy box, allowing the aromatherapy medium to flow in by gravity. The slow-release fibers absorb the aromatherapy and release it slowly, preventing excessive evaporation or excessively high local concentrations. Simultaneously, the evaporation ring is located on the outer periphery of the motor assembly, and the airflow generated by the motor can evenly diffuse aromatherapy molecules throughout the space, achieving full-area fragrance coverage. This solves the problems of uneven evaporation and uncontrolled concentration in traditional aromatherapy, allowing users to enjoy clean air while experiencing a comfortable and pleasant aromatherapy environment, enhancing overall user comfort and the ambiance of the setting.

[0016] This invention features an integrated structure that combines air purification, ambient lighting, and aromatherapy functions. A single device simultaneously meets users' multiple needs for air quality optimization, environmental ambiance creation, and fragrance experience, eliminating the need for separate air purifiers, table lamps, aromatherapy diffusers, and other devices. This design significantly saves indoor space, making it particularly suitable for small apartments or scenarios with high space utilization requirements. It also reduces the cost of purchasing multiple devices, simplifies device placement and maintenance, and the organic integration of multiple functions makes the product more comprehensive and practical, meeting users' needs for one-stop home environment optimization and enhancing the overall value of the product.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figures 1-10 This invention provides an air purification device for high-humidity environments with stable and effective fragrance diffusion, comprising an electronic control component 1, an air outlet mesh 2, a motor component 3, an upper shell component 4, a fragrance box 5, a dust sensor 6, a light cover 7, a light guide ring 8, a light strip 9, a light shielding ring 10, a lower shell 11, a filter 12, a bottom cover 13, a liquid collection tank 14, an overflow hole 15, a volatile ring 16, and a slow-release fiber 17. The upper shell component 4 and the lower shell 11 are assembled into the main body of the device by a fixing mechanism, integrating fragrance release, condensate drainage, light effect optimization, and intelligent linkage. The three core components enable coordinated operation of air purification, fragrance adjustment, and ambient lighting. The motor assembly 3 is integrated inside the upper shell assembly 4. The filter 12 is adapted to the lower shell 11 for installation. The fragrance box 5 and the evaporation ring 16 are snapped together to form a fragrance release unit. The liquid collection tank 14 and the overflow hole 15 work together to form a condensate drainage channel. The light strip 9, the light guide ring 8, and the light shielding ring 10 form a light efficiency optimization structure. The dust sensor 6 is electrically connected to the electronic control assembly 1 to achieve intelligent control. The overall structure takes into account both functional integration and ease of maintenance through modular design.

[0030] The fragrance release mechanism includes a fragrance box 5, an evaporation ring 16, and slow-release fibers 17. The fragrance box 5 adopts a push-button snap-on structure with a two-way elastic reset mechanism, allowing it to pop out quickly when pressed, facilitating the addition of fragrance medium. After closing, it fits precisely with the upper shell assembly 4. The evaporation ring 16 is detachably connected to the fragrance box 5 via a snap-on mechanism. Its bottom is higher than the bottom of the fragrance box 5. An annular evaporation groove is formed on the inner side of the evaporation ring 16, and the slow-release fibers 17 are filled in the evaporation groove in an array structure, adhering tightly to the groove wall. When aromatherapy medium is added to the aromatherapy box 5, the medium can flow by gravity into the evaporation tank and be adsorbed by the slow-release fiber 17, avoiding excessive evaporation or excessively high local concentration. The evaporation ring 16 is located on the outer periphery of the motor assembly 3. When the motor assembly 3 is working, it generates an outward airflow, which drives the aromatherapy medium adsorbed on the slow-release fiber 17 to diffuse evenly to all parts of the space, achieving full coverage of fragrance. At the same time, the detachable connection method makes it convenient for users to clean the evaporation ring 16 and replace the slow-release fiber 17 regularly, ensuring the cleanliness of fragrance release.

[0031] The condensate drainage mechanism consists of a condensate collection tank 14, an overflow hole 15, and a base structure of a lower shell 11. The condensate collection tank 14 adopts an annular groove design, which is precisely arranged to correspond to the bottom contour of the filter 12 and fits into the bottom of the filter 12. It can comprehensively collect the condensate and a small amount of dust generated by the filter 12 in a humid environment. The tank wall of the condensate collection tank 14 has an inclined structure to guide the condensate to flow towards the overflow hole 15, preventing the condensate from accumulating in the tank. The overflow hole 15 is a micron-level through hole located at the lower part of the side wall of the condensate collection tank 14. It can prevent external dust from entering the condensate collection tank 14 and causing pollution, and can also discharge excess condensate in time to prevent the condensate from overflowing and contaminating the internal components of the equipment. Through the combination of comprehensive collection and directional drainage, this mechanism reduces the risk of bacteria growth and corrosion of parts inside the equipment by condensate and dust, while ensuring the cleanliness of the equipment and extending the service life of the filter 12 and the motor assembly 3.

[0032] The light effect optimization and intelligent linkage mechanism includes a light strip 9, a light guide ring 8, a light shielding ring 10, a dust sensor 6, and an electronic control component 1. The light strip 9 is arranged in a circular array evenly inside the light shielding ring 10 and is fixed by ribs and adhesive backing to achieve concealed installation and seamless integration with the equipment shell. The light guide ring 8 and the light shielding ring 10 adopt an integrated nested structure. The two work together to optimize the light propagation path, avoid glare, and make the light diffuse softly and evenly. The light cover plate 7 covers the outside of the light guide ring 8 to further regulate the light effect. The dust sensor 6 is mounted on the upper shell component 4 and electrically connected to the electronic control component 1. It can monitor the concentration of pollutants in the air in real time and transmit the monitoring data to the electronic control component 1. The electronic control component 1 controls the color switching of the light strip 9 according to the data changes, providing intuitive feedback on the air quality status. Users can adjust the color and dynamic effects of the light strip 9 through touch buttons to adapt to the atmosphere needs of different scenarios such as home, office, and entertainment, realizing the dual functions of intelligent interaction and personalized light effect adjustment.

[0033] The sealing and fixing mechanism includes the connection structure between the upper shell assembly 4 and the lower shell 11, and the sealing structure between the filter 12 and the base of the lower shell 11. The upper shell assembly 4 and the lower shell 11 are connected by a fixing mechanism consisting of a snap-fit ​​and a quick-twist lock combination, which is evenly distributed circumferentially along the mating surface. This not only enables the rapid assembly of the main body of the equipment but also ensures the connection is firm, avoiding loosening caused by a single connection method. The filter 12 and the base of the lower shell 11 are provided with an annular sealing groove, in which a silicone sealing ring is installed. The sealing groove and the bottom boss of the filter 12 fit precisely. The silicone sealing ring eliminates the assembly gap through elastic deformation, preventing unfiltered air from escaping from the gap and improving the purification efficiency. At the same time, the sealing ring can buffer the vibration generated during the operation of the equipment, effectively protecting the filter 12, reducing component wear, and balancing sealing performance and structural stability.

[0034] Among them, the device contains:

[0035] The electrical control component 1 is the core of the equipment control. It is electrically connected to the dust sensor 6, receives monitoring data, controls the operation of the motor component 3 and the light strip 9, and realizes intelligent linkage and mode adjustment.

[0036] The air outlet mesh 2 is fixedly installed at the top, with a porous structure, corresponding to the air outlet side of the motor assembly 3, guiding the purified airflow with fragrance to be discharged in an orderly manner.

[0037] The motor assembly 3 is integrated inside the upper shell assembly 4, providing air circulation power. The outer periphery is surrounded by a volatilization ring 16, and the airflow can drive the aroma molecules to diffuse evenly.

[0038] The upper shell assembly 4 and the lower shell 11 together form the main body of the equipment, which carries the electrical control assembly 1, the motor assembly 3, the aromatherapy box 5, the dust sensor 6, etc., and is the core installation carrier.

[0039] The aromatherapy box 5 has a press-button snap structure and is detachably connected to the evaporation ring 16. It stores the aromatherapy medium and allows the medium to flow into the evaporation ring 16 by gravity through the height difference, making it easy to replenish.

[0040] Dust sensor 6 is installed on the upper housing component 4 to monitor the concentration of pollutants in the air in real time and transmit the data to the electronic control component 1, which in turn triggers the light strip 9 to provide feedback on air quality.

[0041] The light cover plate 7 covers the outside of the light guide ring 8, which regulates the propagation of light, further optimizes the light effect, and makes the light more uniform and soft.

[0042] The light guide ring 8 and the light shielding ring 10 are nested together to optimize the light path, avoid glare, and make the light diffuse softly, thus enhancing the atmosphere.

[0043] The light strip 9 is installed in a ring array hidden inside the light-shielding ring 10. It is made of low-power LED material, and can adjust the color / dynamic effects, reflect air quality, and adapt to the scene atmosphere.

[0044] The light-shielding ring 10 is located between the lower shell 11 and the light guide ring 8, wrapping the light strip 9 to achieve hidden installation. It works with the light guide ring 8 to optimize light effect and prevent light leakage and glare.

[0045] The lower shell 11 and the upper shell assembly 4 constitute the main body, and the filter 12 is installed inside. The base is provided with a sealing groove and a liquid collection tank 14, which are the installation parts of the filter 12 and the supporting parts of the bottom structure.

[0046] The filter 12 has a multi-layer composite structure, consisting of pre-filter, HEPA filter, and activated carbon, which intercepts impurities and particulate matter, and adsorbs harmful gases and odors. The bottom corresponds to the liquid collection tank 14.

[0047] The bottom cover 13 is installed at the bottom of the lower shell 11 to form a liquid collection chamber 14. It works in conjunction with the lower shell 11 to stabilize the bottom structure and facilitates regular cleaning of liquid and dust by the user.

[0048] The liquid collection tank 14 has an annular groove structure corresponding to the bottom of the filter 12 to collect condensate and shed dust. The inclined tank wall guides the liquid to the overflow hole 15 to avoid accumulation.

[0049] The overflow hole 15 is located on the lower part of the side wall of the liquid accumulation tank 14. It is a micron-sized through hole that can discharge excess liquid in a timely manner and prevent external dust from entering and contaminating the liquid accumulation tank 14.

[0050] The evaporation ring 16 is made of ABS material and is detachably connected to the aromatherapy box 5 via buckles and slots. Its bottom is higher than the aromatherapy box 5 and has an evaporation groove to support the slow-release fibers 17.

[0051] The slow-release fibers 17 are arrayed and filled in the volatilization groove of the volatilization ring 16, adhering to the groove wall. After adsorbing the fragrance medium, they are slowly released to avoid excessive or insufficient fragrance and achieve uniform slow release.

[0052] Working principle:

[0053] In the first step, after the equipment is started, the electrical control component 1 is powered on and enters the working state, simultaneously sending operating commands to the motor component 3, dust sensor 6, and light strip 9. Upon receiving the command, the motor component 3 starts running, providing power for air circulation. The dust sensor 6 begins to monitor the concentration of pollutants such as PM2.5 particles in the surrounding air in real time, continuously collecting air quality data. The light strip 9 enters the initial standby state, relying on the hidden fixing structure achieved by the light shielding ring 10 through the ribs and adhesive backing to maintain seamless integration with the equipment shell. The light cover plate 7 covers the outside of the light guide ring 8, preparing for the subsequent light effect presentation. During the entire initial start-up phase, all components respond in concert to ensure that the equipment quickly enters the working ready state.

[0054] In the second step, the motor assembly 3 continuously operates to generate a stable airflow, which draws the surrounding air into the device under the action of air pressure difference. The airflow flows along the gap between the lower shell 11 and the filter 12, and passes through the multi-layer composite filtration structure composed of the pre-filter, HEPA filter and activated carbon filter built into the filter 12. The pre-filter intercepts impurities such as hair and large dust particles, the HEPA filter efficiently captures fine particulate matter and bacteria, and the activated carbon filter adsorbs harmful gases and odors, completing comprehensive purification. At the same time, the condensate and a small amount of detached dust generated at the bottom of the filter 12 flow into the liquid collection tank 14 along the inclined structure of the base of the lower shell 11, avoiding accumulation inside the device and ensuring a stable and efficient purification process.

[0055] In the third step, the aromatherapy medium pre-added inside the aromatherapy box 5 flows into the annular evaporation groove of the evaporation ring 16 due to the structural design of the bottom of the evaporation ring 16 being higher than the bottom of the aromatherapy box 5. The slow-release fibers 17 filled in the groove quickly absorb the aromatherapy medium, achieving slow and uniform release. At this time, the airflow generated by the motor assembly 3 flows through the outer periphery of the evaporation ring 16, causing the evaporating aromatherapy molecules to move with the airflow. They are then guided through the internal channel of the upper shell assembly 4 to the air outlet mesh 2, and finally diffused to all parts of the space in sync with the purified air, forming a comfortable fragrance environment that covers the entire area. The push-button snap structure adopted by the aromatherapy box 5, as well as the detachable snap connection between the evaporation ring 16 and the aromatherapy box 5, also provides convenience for subsequent replenishment of aromatherapy medium and cleaning and maintenance.

[0056] In the fourth step, the dust sensor 6 continuously transmits the real-time air quality data to the electronic control component 1. After analyzing and processing the data, the electronic control component 1 controls the light strip 9 to switch the corresponding color according to the changes in pollutant concentration. For example, it displays green when the air quality is good and switches to red when PM2.5 exceeds the standard. The light guide ring 8 and the light shielding ring 10 work together to optimize the light propagation, making the light soft and uniform, allowing users to intuitively understand the air quality status. Users can adjust the color and dynamic effects of the light strip 9 by touching the button to adapt to different needs such as home decoration, office atmosphere creation, and entertainment scene enhancement. At the same time, the electronic control component 1 can automatically switch to energy-saving mode according to the air quality, reducing the power consumption of the motor component 3 and the light strip 9, achieving the dual effects of energy saving, environmental protection and intelligent interaction.
