Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, specifically to air purifiers. Background Technology

[0002] With the improvement of living standards, air purifiers have become standard appliances in many homes and offices. Users not only focus on their core purification performance, but also have higher requirements for the product's appearance, human-computer interaction experience, and integration with home décor. As the core component for user interaction with the device, the design of the display module directly affects the overall aesthetics and user experience of the product.

[0003] However, traditional air purifiers mostly use ordinary LED digital tubes or LCD screens, which emit light directly and harshly, lacking visual softness and a sense of sophistication. They are difficult to integrate with high-end home environments and cannot meet users' growing demand for product aesthetic value. Furthermore, the direct light emission may be glaring when used at night, interfering with users and resulting in a poor user experience. Summary of the Invention

[0004] In view of this, the present invention provides an air purifier to solve the problem that the display light of the existing air purifier lacks visual softness and is glaring when used at night, thus interfering with the user.

[0005] This invention provides an air purifier, including a housing and a display module disposed on the top of the housing, the display module comprising: Display bracket, and display lights mounted on the display bracket; The lampshade and the lamp holder for supporting the lampshade, the lampshade being made of crystal or crystal-like translucent material; The display bracket passes at least partially through the lampshade and is detachably connected to the lamp holder to limit the lampshade between the display bracket and the lamp holder; The indicator light is configured to emit light, and the light is able to shine onto the lampshade and be refracted and / or scattered by the lampshade.

[0006] Beneficial Effects: The air purifier's display module utilizes a lampshade made of crystal or crystal-like translucent material. This allows the light emitted from the display lamp to be refracted and / or scattered in all directions after hitting the lampshade, creating a soft, three-dimensional halo effect. This enhances the overall refined and high-end appearance of the unit, improving the product's visual quality and user experience. It also effectively prevents the display lamp's light from shining directly outwards, avoiding glare and user interference. Furthermore, this application employs a clamping design between the display bracket and the lamp holder for lampshade installation. This not only ensures a secure and stable installation but also avoids the risks associated with screw-based fixing methods, such as damaging the lampshade's integrity and causing stress cracks. It also simplifies lampshade installation and removal, facilitating cleaning and replacement and reducing maintenance costs.

[0007] In one optional embodiment, the display bracket includes a support portion and a connecting portion disposed below the support portion; The indicator light is installed above the support, and the support has a light-transmitting opening to guide the light from the indicator light to the lampshade. The lampshade has a hollow channel in the middle, and the connecting part passes through the hollow channel and is connected to the lamp holder screw.

[0008] Beneficial effects: The display bracket, through its support and connecting parts design, not only mounts the display lights but also connects to the lamp holder, achieving assembly and fixation of the lamp holder, display bracket, and lampshade—a multi-purpose device. By mounting the display panel above the support, the support forms a physical isolation between the display panel and the lampshade, preventing heat accumulation or short-circuit risks. Furthermore, the light-transmitting openings in the support guide light to concentrate on the lampshade, avoiding scattering loss. The cooperation between the connecting part and the hollow channel of the lampshade effectively ensures the coaxiality of the lampshade, display bracket, and lamp holder, preventing lampshade misalignment from affecting light efficiency. In addition, the connecting part and lamp holder are fixed with screws, ensuring a reliable and stable connection and effectively guaranteeing the stability of the product during transportation and use.

[0009] In one optional embodiment, one of the mating parts of the display bracket and the lamp holder is provided with a positioning slot, and the other is provided with a positioning rib. The positioning slot and positioning rib are inserted and matched to limit the position of the display bracket and lamp holder in the circumferential direction.

[0010] Beneficial effects: The combination of positioning ribs and positioning slots not only enables the display bracket and lamp holder to be limited in the circumferential direction, effectively preventing relative rotation of the display bracket and lamp holder during use or assembly, but also plays a role in rapid positioning, enabling the screw connection structure on the display bracket and lamp holder to be quickly aligned, simplifying the assembly alignment process and improving production efficiency.

[0011] In one optional embodiment, the mating parts of the lampshade and the lamp holder are provided with a limiting groove on one side and a limiting rib on the other side. The limiting groove and the limiting convex rib cooperate to limit the lampshade and lamp holder in the circumferential direction.

[0012] Beneficial effects: The limiting groove and the limiting rib cooperate to limit the lampshade and lamp holder in the circumferential direction. The limiting groove and the limiting rib, together with the positioning rib and the positioning slot, form a double anti-rotation mechanism to ensure that the lampshade can maintain high stability even in a vibration environment.

[0013] In one alternative implementation, the display module further includes: The display panel is mounted on the display bracket, and the indicator lights are located below the display panel and correspond to the light covers. The decorative panel has a mounting position in the middle for mounting the display panel, which can be detachably mounted in the mounting position. The decorative panel and the display bracket are secured together by a snap-fit ​​mechanism.

[0014] Beneficial effects: By integrating the decorative panel into the mounting position and installing the display panel in this position, the overall structure is more compact. The decorative panel and the display bracket are fixed by a rotating snap-fit ​​structure, which enables quick assembly and disassembly of the decorative panel and the display bracket, facilitating later maintenance.

[0015] In one alternative implementation, the decorative panel is fastened to the display bracket; The snap fastener structure includes a snap fastener and a slot, one of which is set on the decorative panel and the other is set on the display bracket; One of the knob and the groove is provided with a locking protrusion, and the other is provided with a locking groove; When the decorative panel and display bracket are rotated and engaged into the set assembly position via the buckle and groove, the locking protrusion and locking groove cooperate.

[0016] Beneficial effects: The rotary buckle structure, with its combination of buckles and grooves, is simple in structure and easy to operate. Furthermore, the corresponding locking protrusions and grooves on the buckles and grooves effectively prevent the buckles from slipping out of the grooves, further improving connection reliability and ensuring that the buckles will not easily loosen even under vibration. In addition, the locking protrusions and grooves provide clear tactile and audible feedback when the decorative panel is properly engaged, resulting in a better assembly experience.

[0017] In one alternative implementation, the display module further includes: The display panel is mounted above the decorative panel and at least covers the decorative panel.

[0018] Beneficial effects: By installing a display panel on the decorative panel, the gap between the display panel and the decorative panel can be hidden, resulting in a clean interface. In addition, the display panel can effectively prevent dust from entering the display module and extend the service life of the display module.

[0019] In one optional embodiment, the housing has an air inlet in the middle, an upper air outlet and a lower air outlet at the top and bottom, respectively, and the display module is located at the upper air outlet. The top of the casing is open to form an upper air outlet, and an air outlet grille is installed inside the upper air outlet. The air outlet grille is circular, and a clearance opening is formed in the middle of the air outlet grille to allow the display module to be exposed.

[0020] Beneficial effects: By setting the air outlet grille to be ring-shaped, and the opening in the middle of the ring-shaped air outlet grille serving as a clearance opening for the display module to be exposed, the air outlet and display functions do not interfere with each other, while the clearance opening can also meet the heat dissipation requirements of the display module.

[0021] In one alternative implementation, the air purifier further includes: The upper fan assembly, housed within the housing, is used to drive external air to flow from the air inlet to the air outlet. The downdraft fan assembly, housed within the housing, is used to drive external air to flow from the air inlet to the air outlet. The filter module is located at the air inlet, between the upper fan assembly and the lower fan assembly. The filter module is used to filter and purify the air entering from the air inlet.

[0022] Beneficial effects: The upper and lower fan components form two completely independent drive systems, which can be controlled and adjusted separately, enabling multiple operating modes, such as sleep mode using only upper airflow and powerful mode using both upper and lower airflow simultaneously. This greatly increases the product's functional versatility and adaptability to various scenarios. Furthermore, only one filter module needs to be installed at the air inlet, compared to the existing system requiring two separate filter modules for upper and lower air inlets. This simplifies the overall structure, production and assembly process, and reduces material costs and filter maintenance complexity.

[0023] In one alternative embodiment, the upper fan assembly includes a second bracket and a second fan mounted on the second bracket, and the air purifier further includes: Air quality light, used to display air quality information; The light fixture is mounted on the light fixture. The outer periphery of the second bracket bends outward to form an installation space for the light fixture, which is then embedded within the installation space.

[0024] Beneficial effects: The air quality light provides real-time air quality information, eliminating the need to rely on a screen or app for intuitive air quality perception and improving user experience. Furthermore, utilizing the installation space created by the outward folding of the second bracket to mount the light holder and air quality light results in a more compact overall structure, reducing the need for additional brackets, lowering material costs and assembly steps.

[0025] In one optional implementation, the air purifier further includes: The deodorization module is located at the lower air outlet. The deodorization module includes a plasma generator, which can generate plasma by discharge to decompose odors in the air.

[0026] Beneficial effects: By using a plasma generator at the lower air outlet, high-density plasma can be generated. Through discharge, it catalytically degrades harmful gases, thereby deeply decomposing residual odors, formaldehyde, TVOC and other gaseous pollutants in the clean air to be discharged, completely eliminating odors. This makes up for the shortcomings of traditional filters, which are mainly effective against particulate matter and have limited efficiency in removing gaseous pollutants, thus expanding the purification capabilities of air purifiers.

[0027] In one alternative embodiment, the downwind assembly includes a first fan and a first bracket for mounting the first fan. The plasma generator is installed on the outer periphery of the first support and corresponds to the lower air outlet. The plasma generator and the first support enclose each other to form a lower air duct. The downdraft duct connects the air inlet and the downdraft outlet, and the first fan is located inside the downdraft duct. Beneficial effects: By integrating the deodorization module with the downdraft fan assembly, the first bracket not only secures the fan but also serves as the mounting base for the duct wall and the deodorization module. This achieves modular and integrated design of functional components, significantly saving internal space and making the overall layout more rational and compact, with higher space utilization. Furthermore, by directly placing the plasma generator inside the downdraft duct and facing the downdraft outlet, it ensures that all air blown from the bottom passes through the plasma zone, thereby guaranteeing the effectiveness and consistency of deodorization treatment.

[0028] In one alternative implementation, the lower air outlets are distributed on at least two sides of the housing; The plasma generator is provided with at least two sets, and the air outlets of the at least two sets of plasma generators are located on at least two sides of the first bracket. At least two sets of plasma generating devices are enclosed with the first support to form a downdraft duct that is closed at the bottom, draws air at the top, and discharges air from at least two sides.

[0029] Beneficial Effects: The bottom air outlet features a design with airflow from at least two sides, resulting in a wider airflow direction at the bottom. This allows for faster filling of the entire bottom space with clean air, reducing purification dead zones, improving air exchange efficiency, and achieving multi-directional and uniform bottom airflow. Furthermore, plasma generators are installed in multiple airflow directions, ensuring effective odor decomposition regardless of the airflow direction. This achieves full coverage of odor removal in the bottom airflow area, significantly enhancing the product's ability to handle complex odor environments. In addition, the "bottom-closed, top-suction, multi-directional airflow" duct structure formed by the plasma generator and the first support is highly efficient and rational, conforming to the working characteristics of a centrifugal fan. It effectively guides airflow, gathers purified air from the center, and evenly distributes it from multiple directions.

[0030] In one optional embodiment, the plasma generating device includes: The mounting bracket forms an electrode mounting area; Several electrode structures are arranged at intervals along the length of the mounting frame in the electrode mounting area; There is a discharge gap between two adjacent electrode structures and between the electrode structure and the mounting bracket to allow airflow.

[0031] Beneficial effects: By using multiple electrode structures spaced along the length of the mounting frame, a large plasma generation area can be formed, increasing the plasma reaction area and improving processing efficiency. Furthermore, the multiple electrode structures ensure that airflow passes through these dense discharge gaps as it flows from the inlet to the outlet, increasing the probability and time for pollutants to collide with high-energy plasma, resulting in more complete and efficient odor decomposition. In addition, the design of the discharge gaps allows for normal airflow, preventing excessive resistance to the air duct caused by overly dense structures, which could affect the overall airflow.

[0032] In one optional implementation, the filtering module includes: Filter screen; A filter support structure, wherein a filter installation space is formed within the filter support structure, and the filter is rotatably installed within the filter installation space; The upper fan assembly is detachably mounted above the filter support structure, and the lower fan assembly is detachably mounted below the filter support structure; The air purifier also includes: An ultraviolet sterilization module is installed on the filter support structure and located on one side of the filter, and is used to perform ultraviolet sterilization on the filter.

[0033] Beneficial Effects: The filter support structure, with its frame structure and ample storage space, facilitates daily cleaning and filter replacement, reducing maintenance costs. Furthermore, the upper and lower fan components are installed above and below the filter support structure, making full use of vertical space and resulting in a more compact overall structure with high space utilization, suitable for space-constrained applications. The filter support structure not only houses the filter but also serves as a support for the upper and lower fan components, offering multiple uses and simplifying the structure. In addition, by making the filter rotatable and placing the UV sterilization module 60 on one side, the entire outer surface of the rotating filter can be uniformly irradiated 360 degrees without blind spots, ensuring thorough and efficient sterilization and effectively inhibiting bacterial growth.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, in one aspect, such as Figures 1 to 6 , Figures 11 to 17As shown, the present invention provides an air purifier, including a housing 10 and a display module 70 disposed on the top of the housing 10. The display module 70 includes a display bracket 71, a display lamp 74 mounted on the display bracket 71, a lampshade, and a lamp holder 73 for supporting the lampshade 72. The lampshade 72 is made of crystal or a crystal-like translucent material. The display bracket 71 at least partially passes through the lampshade 72 and is detachably connected to the lamp holder 73 to limit the lampshade 72 between the display bracket 71 and the lamp holder 73. The display lamp 74 is configured to emit light, and the light can illuminate the lampshade 72 and be refracted and / or scattered by the lampshade 72.

[0043] In the above embodiments, the display module 70 of the air purifier uses a lampshade 72 made of crystal or crystal-like translucent material. This allows the light emitted by the display lamp 74 to be refracted and / or scattered in all directions after hitting the lampshade 72, creating a soft, three-dimensional halo effect. This makes the overall appearance more refined and high-end, improving the product's visual quality and user experience. It also effectively prevents the light from the display lamp 74 from shining directly out, causing glare and user interference. Furthermore, this application uses a clamping design between the display bracket 71 and the lamp holder 73 to install the lampshade 72. This not only ensures a secure and stable installation of the lampshade 72 but also avoids the risks of damaging the integrity of the lampshade 72 and causing stress cracks associated with fixing the lampshade 72 with screws or similar methods. It also makes the installation and removal of the lampshade 72 easier, facilitating later cleaning or replacement and reducing maintenance costs.

[0044] Specifically, in this embodiment, the lampshade 72 is made of crystal and is a spherical or hemispherical crystal ball. Preferably, the lampshade 72 in this embodiment is hemispherical to facilitate its fit with the plate-shaped components such as the display panel 79, display panel 76, and decorative panel 75 above it. The lamp holder 73 is a bowl-shaped component that matches the shape of the lampshade 72. A hollow channel running through the center of the lampshade 72 is provided, and the lower end of the display bracket 71 passes through the hollow channel and connects to the lamp holder 73. The display bracket 71 and the lamp holder 73 are connected by screws or snap-fit. Preferably, to ensure the stability of the connection between the display bracket 71, the lamp holder 73, and the lampshade 72, the display bracket 71 and the lamp holder 73 are connected by screws.

[0045] In some embodiments, such as Figure 13 , Figure 16 and Figure 17 As shown, the display bracket 71 includes a support portion 711 and a connecting portion 712 located below the support portion 711; the display lamp 74 is mounted above the support portion 711, and the support portion 711 is provided with a light-transmitting opening 7110 that guides the light of the display lamp 74 to illuminate the lamp cover 72; the lamp cover 72 has a hollow channel in the middle, and the connecting portion 712 passes through the hollow channel and is screwed to the lamp holder 73.

[0046] In the above embodiments, the display bracket 71, through the design of the support part 711 and the connecting part 712, can not only install the display lamp 74, but also connect with the lamp holder 73, realizing the assembly and fixation of the lamp holder 73, display bracket 71, and lamp cover 72, serving multiple purposes in one device. By mounting the display panel 79 above the support part 711, the support part 711 can form a physical isolation between the display panel 79 and the lamp cover 72, avoiding the risk of heat accumulation or short circuit. Furthermore, the light-transmitting opening 7110 on the support part 711 can guide the light to concentrate on the lamp cover 72, avoiding scattering loss. The cooperation between the connecting part 712 and the hollow channel of the lamp cover 72 can effectively ensure the coaxiality of the lamp cover 72, display bracket 71, and lamp holder 73, preventing the lamp cover 72 from shifting and affecting the light efficiency. In addition, the connecting part 712 and the lamp holder 73 are fixed by screw connection, which is reliable and stable, effectively ensuring the stability of the product during transportation and use.

[0047] Specifically, the support portion 711 is an annular plate structure, and the connecting portion 712 is a cylindrical structure. The upper circumferential edge of the cylindrical connecting portion 712 is connected to the inner ring edge of the annular support portion 711. There are multiple sets of indicator lights 74, which are arranged at intervals along the circumference of the support portion 711, and multiple sets of light-transmitting openings 7110 are provided accordingly.

[0048] Furthermore, such as Figure 13 , Figure 14 , Figure 17 As shown, the lower end of the connecting part 712 is provided with a bolt post, and the lamp holder 73 is provided with a connecting hole. A screw is connected between the connecting hole and the bolt post. Preferably, at least two sets of bolt posts are symmetrically provided on the connecting part 712 to further improve the stability of the connection between the lamp holder 73 and the display bracket 71. In some embodiments, one of the mating parts of the display bracket 71 and the lamp holder 73 is provided with a positioning slot 713 and the other is provided with a positioning rib 731; the positioning slot 713 and the positioning rib 731 are inserted and mated to limit the display bracket 71 and the lamp holder 73 in the circumferential direction.

[0049] In the above embodiments, the cooperation of the positioning rib 731 and the positioning slot 713 can not only limit the display bracket 71 and the lamp holder 73 in the circumferential direction, effectively preventing the display bracket 71 and the lamp holder 73 from rotating relative to each other during use or assembly, but also play a role in rapid positioning, so that the screw connection structure on the display bracket 71 and the lamp holder 73 can be quickly aligned, simplifying the assembly alignment process and improving production efficiency.

[0050] Specifically, the display bracket 71 is provided with a positioning slot 713, the lamp holder 73 is provided with a positioning rib 731, the bottom edge of the connecting part 712 of the display bracket 71 is provided with a notch, the notch forms the positioning slot 713, and the bottom inner peripheral wall of the lamp holder 73 is provided with a strip rib, the strip rib forms the positioning rib 731.

[0051] Preferably, there are at least two sets of positioning ribs 731 and positioning slots 713, which are arranged at intervals.

[0052] In some embodiments, such as Figure 14 and Figure 15 As shown, one of the mating parts of the lampshade 72 and the lamp holder 73 is provided with a limiting groove 732 and the other is provided with a limiting rib 721; the limiting groove 732 and the limiting rib 721 are in concave-convex fit to realize the limiting of the lampshade 72 and the lamp holder 73 in the circumferential direction.

[0053] In the above embodiments, the limiting groove 732 and the limiting rib 721 cooperate to limit the lamp cover 72 and the lamp holder 73 in the circumferential direction. The limiting groove 732 and the limiting rib 721, together with the positioning rib 731 and the positioning slot 713, form a double anti-rotation mechanism to ensure that the lamp cover 72 can maintain high stability even in a vibration environment.

[0054] In some embodiments, the display module 70 further includes a display panel 79 and a decorative panel 75. The display panel 79 is mounted on the display bracket 71, and the display lamp 74 is disposed below the display panel 79 and corresponds to the lamp cover 72. The decorative panel 75 has a mounting position in the middle for mounting the display panel 79, and the display panel 79 is detachably mounted in the mounting position. The decorative panel 75 and the display bracket 71 are engaged and fixed by a snap-fit ​​structure.

[0055] In the above embodiment, by integrating the mounting position of the decorative panel 75 and installing the display panel 79 in the mounting position, the overall structure is relatively compact. The decorative panel 75 and the display bracket 71 are fixed by rotating and snapping together through a snap-lock structure, which can realize the quick assembly and disassembly of the decorative panel 75 and the display bracket 71, and facilitate later maintenance. Specifically, the display panel 79 is reliably fixed to the mounting position of the decorative panel 75 using four stainless steel self-tapping screws; the decorative panel 75 and the display bracket 71 are integrated with four sets of symmetrically distributed screw structures, and the decorative panel 75 and the display bracket 71 are precisely matched through the four sets of screw structures to achieve a 360° tightening connection.

[0056] In some embodiments, such as Figure 4 , Figure 13 and Figure 17As shown, the decorative panel 75 is fastened to the display bracket 71; the snap fastener structure includes a snap fastener 751 and a slot 714, one of which is disposed on the decorative panel 75 and the other on the display bracket 71; one of the snap fastener 751 and the slot 714 is provided with a locking protrusion 752 and the other with a locking groove 715; when the decorative panel 75 and the display bracket 71 are rotated and engaged to the set assembly position by the snap fastener 751 and the slot 714, the locking protrusion 752 and the locking groove 715 engage.

[0057] In the above embodiments, the snap fastener structure, by adopting a snap fastener 751 and a groove 714, has a simple structure and is easy to operate. Furthermore, the locking protrusion 752 and locking groove 715 correspondingly provided on the snap fastener 751 and the groove 714 can effectively prevent the snap fastener 751 from falling out of the groove 714 in the opposite direction, further improving the reliability of the connection and ensuring that the snap fastener 751 will not easily loosen even in a vibration environment. In addition, the locking protrusion 752 and locking groove 715 can provide clear tactile and audible feedback when the decorative panel 75 is engaged, resulting in a better assembly experience.

[0058] Specifically, the decorative panel 75 includes a panel body and a fastening part disposed below the panel body. The fastening part is cylindrical, and the outer periphery of the support part 711 is bent upward to form a folded edge. That is, the outer periphery of the support part 711 is bent upward to form a folded edge, and the fastening part extends into the folded edge. A swivel 751 is provided on the outer peripheral wall of the fastening part, and a swivel groove 714 is provided on the inner periphery of the folded edge. A portion of the swivel 751 is recessed inward to form a locking groove 715, and a locking protrusion 752 is fixedly disposed in the swivel groove 714. During assembly, the decorative panel 75 is fastened above the display bracket 71 and covers the display panel 79, the display bracket 71, and the lampshade 72. The fastening part extends into the folded edge above the display bracket 71, and then the decorative panel 75 is rotated along the set installation direction until the locking groove 715 engages with the locking protrusion 752.

[0059] In some embodiments, the display module 70 further includes a display panel 76 mounted above the decorative panel 75 and at least covering the display panel 79.

[0060] In the above embodiments, by providing a display panel 76 on the decorative panel 75, the gap between the display panel 79 and the decorative panel 75 can be hidden, resulting in a clean interface. Furthermore, the display panel 76 can effectively prevent dust from entering the display module 70 and extend the service life of the display module 70.

[0061] Specifically, the back of the display panel 76 is attached to the decorative panel 75 by a high-adhesion adhesive.

[0062] In some embodiments, the housing 10 has an air inlet 100 in the middle, an upper air outlet 101 and a lower air outlet 102 at the top and bottom respectively, and the display module 70 is located at the upper air outlet 101; the top of the housing is open to form the upper air outlet 101, and an air outlet grille 12 is installed inside the upper air outlet 101. The air outlet grille 12 is annular, and an avoidance opening is formed in the middle of the air outlet grille 12 to allow the display module 70 to be exposed.

[0063] In the above embodiment, by setting the air outlet grille 12 as an annular shape, the opening in the middle of the annular air outlet grille 12 serves as a clearance opening for the display module 70 to be exposed, so that the air outlet and display functions do not interfere with each other, while the clearance opening can also meet the heat dissipation requirements of the display module 70.

[0064] This application employs a central air intake and top and bottom air outlet design. Compared to top and bottom air intake and central air outlet purification methods, this effectively avoids the problems associated with bottom air intake, which can easily draw dust, hair, and other foreign objects from the ground directly into the filter, causing filter blockage and even affecting filter performance and lifespan. This reduces the frequency of filter cleaning, extends filter life, and lowers maintenance costs. On the other hand, traditional central air outlet designs often produce a strong direct airflow, which can easily cause user discomfort or even interfere with concentration in quiet environments such as sleeping or working. However, the central air intake and top and bottom air outlet design of this application allows purified air to be delivered from the top and bottom simultaneously, forming a "surrounding" airflow purification path indoors. This ensures that purified air is evenly distributed around the user, completely eliminating direct airflow interference. It is particularly suitable for quiet environments such as sleeping and working, achieving "imperceptible purification," significantly improving user comfort, and enhancing the adaptability of the air purifier in various environmental applications to meet the needs of different users in various usage scenarios.

[0065] In some embodiments, the air inlet 100 is arranged around the middle peripheral wall of the air purifier; the upper air outlet 101 is located on the top surface of the air purifier; and the lower air outlet 102 is arranged around the bottom peripheral wall of the air purifier.

[0066] In the above embodiment, the air inlet 100, through its surrounding design, increases the effective air intake area, allowing more air to be purified to quickly enter the device. This provides a structural basis for achieving a large air volume and a high clean air output ratio, thereby improving the initial purification efficiency of the entire unit. Furthermore, by placing the upper air outlet 101 on the top surface of the air purifier, it facilitates the upward diffusion and natural downward flow of clean air, forming a gentle vertical airflow. The bottom circumferential air outlet design delivers air horizontally to the far end of the room. This combination of upper and lower air outlets creates a uniform and gentle airflow, completely avoiding discomfort caused by direct airflow onto the human body. It is particularly suitable for bedrooms, studies, and other scenarios where quietness and comfort are paramount. In one specific example, the air purifier includes a housing 10 with an open top and an air outlet grille 12 to form an upper air outlet 101. An air inlet 100 and a lower air outlet 102 surround at least two sides of the housing 10.

[0067] In a specific example, the air inlet 100 is located on the back and two sides of the air purifier; the lower air outlet 102 is located on the back and two sides of the air purifier.

[0068] In the above example, by placing the air inlet 100 and the lower air outlet 102 on the back and two sides of the air purifier, instead of the front, the front panel does not need to have a functional air inlet 100 or air outlet, thus maintaining the product's front appearance and cleanliness. In order to facilitate the maintenance and replacement of the filter, deodorization module 50, etc. inside the air purifier, a large disassembly port needs to be opened on the outer shell 10. By placing this disassembly port on the back of the outer shell 10 and installing the air inlet grille 11 on the disassembly port, the structure can be hidden, making it convenient to disassemble and maintain the internal components of the outer shell 10. It can also serve as an air inlet 100 or air outlet for air intake and exhaust, while maintaining a complete and simple appearance, making it easier to integrate into home decoration styles and enhancing the product's aesthetic value.

[0069] In some embodiments, the air purifier includes a fan assembly, with an air inlet 100, an upper air outlet 101, and a lower air outlet 102 all disposed in the housing 10; the fan assembly is disposed inside the housing 10, and the fan assembly is used to drive external air into the housing 10 from the air inlet 100 and then flow to the upper air outlet 101 and the lower air outlet 102 respectively.

[0070] In the above embodiment, the fan assembly is used as the direct power source to form a "surround airflow path". It can pressurize the air to be purified drawn in by the central air inlet 100 and send it out from the top and bottom air outlets respectively.

[0071] In some embodiments, the fan assembly includes an upper fan assembly 21 and a lower fan assembly 22. The upper fan assembly 21 is disposed at the top position inside the housing 10 and is used to drive external air to flow from the air inlet 100 to the air outlet 101. The lower fan assembly 22 is disposed at the top position inside the housing 10 and is used to drive external air to flow from the air inlet 100 to the air outlet 102.

[0072] In the above embodiments, the upper fan assembly 21 and the lower fan assembly 22 form two completely independent drive systems that can be controlled and adjusted separately, thereby enabling multiple working modes, such as sleep mode using only the upper fan and strong mode using both upper and lower fans, which greatly increases the product's functional diversity and scenario adaptability.

[0073] In some embodiments, the air purifier further includes a filter module 30, which is disposed at the air inlet 100 and located between the upper fan assembly 21 and the lower fan assembly 22. After the outside air enters the housing 10 through the air inlet 100, it is filtered by the filter module 30 and then flows to the upper fan assembly 21 and the lower fan assembly 22 respectively. In the above embodiment, the filter module 30 installed at the air inlet 100 can effectively remove particulate pollutants such as PM2.5, pollen, and dust from the air, which is fundamental to ensuring the quality of the exhaust air. Furthermore, only one filter module 30 needs to be installed at the air inlet 100, which simplifies the overall structure, production and assembly process, and reduces material costs and the complexity of filter maintenance compared to existing systems that require two separate filter modules 30 for both top and bottom air inlets.

[0074] Furthermore, the top and bottom of the filter module 30 are respectively formed with an upper purification outlet and a lower purification outlet. The upper fan assembly 21 is installed above the filter support structure and is connected to the upper purification outlet. The lower fan assembly 22 is installed below the filter support structure and is connected to the lower purification outlet. After the external air enters the housing 10 from the air inlet 100, it is filtered by the filter module 30 and flows to the upper fan assembly 21 and the lower fan assembly 22 from the upper purification outlet and the lower purification outlet, respectively.

[0075] In the above embodiment, the air to be purified enters from the central air inlet 100, and after being filtered by the cylindrical filter 31, it naturally splits into two directions, upward and downward, and flows from the upper and lower purification outlets to the corresponding fan components. The airflow path is short and smooth, reducing wind resistance and turbulence, thereby improving the overall purification efficiency.

[0076] In some embodiments, the filter module 30 includes a filter screen 31, which is cylindrical. The top support component 32 and the bottom support component 33 respectively form an upper purification outlet and a lower purification outlet. The upper fan component 21 is disposed between the upper purification outlet and the upper air outlet 101, and the lower fan component 22 is disposed between the lower purification outlet and the lower air outlet 102. After the outside air enters the housing 10 from the air inlet 100, it is filtered by the filter module 30 and then flows from the upper purification outlet to the upper fan component 21 and the lower fan component 22 respectively.

[0077] In some embodiments, such as Figures 1 to 9 As shown, the air purifier also includes an odor removal module 50, which is located at the lower air outlet 102. The odor removal module 50 includes a plasma generator 51, which can generate plasma by discharge to decompose odors in the air.

[0078] In the above embodiment, the plasma generator 51 installed at the lower air outlet 102 can generate high-density plasma, which catalytically degrades harmful gases through discharge. This deeply decomposes residual odors, formaldehyde, TVOCs, and other gaseous pollutants in the clean air to be discharged, completely eliminating odors. This overcomes the shortcomings of traditional filters, which are mainly effective against particulate matter and have limited efficiency in removing gaseous pollutants, thus expanding the purification capabilities of the air purifier. The odor removal module 50 is installed at the lower air outlet 102, while the upper air outlet 101 does not have an odor removal module 50. This design ensures that the air coming out of the upper air outlet 101 does not undergo additional purification and odor removal, maximizing the purification performance and efficiency of the air purifier in odor removal mode.

[0079] In some embodiments, the downdraft assembly 22 includes a first fan 221 and a first bracket 222 for mounting the first fan 221; a plasma generator 51 is mounted on the outer periphery of the first bracket 222 and corresponds to the downdraft outlet 102, and the plasma generator 51 and the first bracket 222 enclose each other to form a downdraft duct; the downdraft duct connects the air inlet 100 and the downdraft outlet 102, and the first fan 221 is located inside the downdraft duct. In the above embodiments, by integrating the deodorization module 50 with the lower fan assembly 22, the first bracket 222 not only fixes the fan but also serves as the duct wall and mounting base for the deodorization module 50, achieving modular and integrated design of functional components. This greatly saves internal space, making the overall layout more reasonable and compact, and increasing space utilization. Furthermore, by directly placing the plasma generator 51 inside the lower duct and facing the lower air outlet 102, it ensures that all air blown from the bottom passes through the plasma area, thereby guaranteeing the effectiveness and consistency of the deodorization process.

[0080] Specifically, such as Figure 9 As shown, the first fan 221 includes a first motor 2211 and a first fan blade 2212. The first motor 2211 and the first fan blade 2212 are connected. The first motor 2211 can drive the first fan blade 2212 to rotate, so as to drive the air entering from the air inlet 100 to flow along the first air duct to the lower air outlet 102. The first motor 2211 is detachably installed and fixed in the first bracket 222, and the first fan blade 2212 is installed on the output shaft above the first motor 2211. The plasma generator 51 has a discharge gap for airflow. When the plasma generator 51 is installed on the first bracket 222, the plasma generator 51 is located on the airflow path from the air inlet 100 to the lower air outlet 102, and the plasma generator 51 has a discharge gap for airflow and discharge purification.

[0081] In some embodiments, the lower air outlet 102 is distributed on at least two sides of the housing 10; at least two sets of plasma generating devices 51 are provided, and the at least two sets of plasma generating devices 51 are arranged on at least two sides of the first bracket 222 corresponding to the lower air outlet 102; the at least two sets of plasma generating devices 51 and the first bracket 222 enclose a lower air duct that is closed at the bottom, draws air at the top, and discharges air from at least two sides.

[0082] In the above embodiment, the lower air outlet 102 adopts a design with air outlets on at least two sides, which makes the bottom air supply direction wider, can push clean air to fill the entire bottom space of the room more quickly, reduce purification dead corners, improve air replacement efficiency, and achieve multi-directional and uniform bottom air outlet. Furthermore, plasma generators 51 are configured in multiple air outlet directions, ensuring effective odor decomposition regardless of the direction of airflow, thus achieving full coverage of odor removal in the bottom air outlet area and significantly enhancing the product's ability to cope with complex odor environments. In addition, the "closed bottom, suction top, multi-directional air outlet" duct structure formed by the plasma generator 51 and the first support 222 is highly efficient and reasonable, conforming to the working characteristics of a centrifugal fan, effectively guiding airflow, gathering purified air from the middle, and uniformly pressing it out from multiple directions.

[0083] In one specific example, the deodorization module 50 is plugged into the first bracket 222 for easy disassembly and maintenance.

[0084] In a specific example, the lower air outlet 102 is provided on three sides of the outer casing 10, the first bracket 222 is provided with three flow openings 2220, and the plasma generator 51 has three sets. The three sets of plasma generators 51 are installed at the three flow openings 2220 to catalytically degrade harmful gases, odors, etc. in the air flowing through the flow openings 2220 through discharge.

[0085] In some embodiments, the first bracket 222 is a frame structure, and the first bracket 222 is provided with an overflow opening 2220 on one side corresponding to the lower air outlet 102; a slot 2221 is formed on the first bracket 222, and the plasma generator 51 is inserted into the slot 2221 and corresponds to the overflow opening 2220.

[0086] In the above embodiment, the frame-type first bracket 222 adopts a slot 2221 design, which facilitates the insertion and removal of the plasma generator 51 as an independent module on the first bracket 222. This not only ensures a stable and reliable connection but also greatly simplifies the production and assembly process, making it easier for users or maintenance personnel to replace or maintain the plasma generator 51, reducing after-sales service costs, and facilitating production and maintenance. Furthermore, the slot 2221 structure design enables accurate positioning, ensuring the precision and consistency of the plasma generator 51's installation position, so that its air outlet surface is precisely aligned with the flow opening 2220 on the bracket, guaranteeing smooth airflow.

[0087] In some embodiments, the plasma generating device 51 includes a mounting frame 511 and a plurality of electrode structures 512, the plurality of electrode structures 512 being arranged at intervals on the mounting frame 511 along the length direction of the mounting frame 511; there is a discharge gap between two adjacent electrode structures 512 and between the electrode structure 512 and the mounting frame 511 for gas flow.

[0088] In the above embodiment, a large plasma generation area can be formed by multiple electrode structures 512 spaced apart along the length of the mounting frame 511, increasing the plasma reaction area and improving processing efficiency. Furthermore, the multiple electrode structures 512 allow airflow to pass through these dense discharge gaps as it flows from the air inlet 100 to the air outlet 102, increasing the probability and time for pollutants to collide with high-energy plasma, resulting in more complete and efficient odor decomposition. In addition, the design of the discharge gaps allows airflow to pass through normally, avoiding excessive resistance to the air duct caused by overly dense structures, which could affect the overall airflow.

[0089] In some embodiments, such as Figure 6 and Figure 9 As shown, the deodorization module 50 also includes a metal mesh cover 52, which is disposed on the side of the plasma generator 51 near the lower air outlet 102. The metal mesh cover 52 is grounded, and the metal mesh cover 52 is used to prevent excessive plasma generated by the plasma generator 51 from overflowing.

[0090] In some embodiments, the deodorization module 50 further includes an ozone reduction mesh 53. A metal mesh cover 52 is disposed between the plasma generator 51 and the ozone reduction mesh 53. The ozone reduction mesh 53 can effectively prevent excessive ozone leakage generated by the discharge of the plasma generator 51.

[0091] Furthermore, along the airflow direction, the plasma generator 51, the metal mesh cover 52, and the ozone reduction mesh 53 are arranged in sequence. The first support 222 is provided with a sliding groove for installing the metal mesh cover 52 and the ozone reduction mesh 53. The metal mesh cover 52 and the ozone reduction mesh 53 are slidably installed in the sliding groove from the side of the first support 222. This design facilitates the disassembly and maintenance of the metal mesh cover 52 and the ozone reduction mesh 53.

[0092] In some alternative embodiments, two sets of partition ribs can be provided in the slot 2221 of the first bracket 222 to divide the space into three slots, which are respectively used to install the plasma generator 51, the metal mesh cover 52 and the ozone reduction mesh 53.

[0093] In some embodiments, the upper fan assembly 21 includes a second fan 211, a second bracket 213 for mounting the second fan 211, and an upper air duct 212; the inlet end of the upper air duct 212 is connected to the upper purification outlet of the filter module 30, and the outlet end is connected to the upper air outlet 101; the second fan 211 is disposed inside the upper air duct 212; the second bracket 213 is installed on the side of the upper air duct 212 away from the filter module 30.

[0094] Specifically, the second fan 211 includes a second motor 2111 and a second fan blade 2112. The second motor 2111 is connected to the second fan blade 2112 and can drive the second fan blade 2112 to rotate, so that the airflow flows from the air inlet 100 to the air outlet 101.

[0095] In some embodiments, such as Figures 2 to 4 As shown, the air purifier also includes an air quality light 77 and a light holder 78. The air quality light 77 is used to display air quality information. The air quality light 77 is mounted on the light holder 78. The outer periphery of the second bracket 213 bends outward to form an installation space for mounting the light holder 78. The light holder 78 is embedded in the installation space.

[0096] In the above embodiment, the air quality light 77 can display air quality information in real time, eliminating the need to rely on a screen or app to intuitively perceive air quality, thus improving the user experience. Furthermore, the installation space formed by the outward folding of the second bracket 213 is used to install the light holder 78 and the air quality light 77, making the overall structure more compact and reducing the need for additional brackets, thereby lowering material costs and assembly steps.

[0097] Specifically, such as Figure 4As shown, the outer periphery of the second bracket 213 extends outward a certain distance and then bends upward to form an upward-facing rolled edge. The air quality lamp 77 is annular, as is the lamp holder 78. The longitudinal section of the lamp holder 78 is H-shaped. The air quality lamp 77 is installed in the opening slot at the top of the H-shaped lamp holder 78. The H-shaped lamp holder 78 and the rolled edge together form a circumferentially enclosed installation space, providing a good limiting effect for the air quality lamp 77. The light from the air quality lamp 77 can be diffused through the lampshade 72, creating a highly three-dimensional effect and combining decorative and practical functions.

[0098] In this embodiment, the lamp holder 73 is installed above the second bracket 213. The outer surface of the lampshade 72 is a high-transmittance curved surface. Preferably, the lampshade 72 is a crystal ball, installed in the axial cavity of the display bracket 71 and the lamp holder 73, and fixed by screws. At the bottom, equally spaced limiting ribs 721 are provided to form a limiting fit with the limiting grooves 732 of the lamp holder 73, effectively preventing rotation. By utilizing the cooperation between the display bracket 71 and the lamp holder 73 and the limiting structure, the lampshade 72 is fixed, ensuring its integrity and avoiding any impact on the display effect caused by screw holes or other connection structures on the lampshade 72. Light-transmitting openings 7110 are opened corresponding to the positions of the display lamps 74 on the display bracket 71 and the display panel 79. The light emitted by the display lamps 74 is precisely irradiated onto the crystal ball through the light-transmitting openings 7110. After refraction and scattering by its high-transmittance curved surface, a soft, three-dimensional halo effect is presented, resulting in a refined and high-end appearance.

[0099] In some embodiments, such as Figure 6 , Figure 8 The air purifier also includes an ultraviolet (UV) sterilization module 60, which is disposed within the outer casing 10 and used to sterilize the filter module 30 with UV light. The filter module 30 includes a cylindrical filter screen 31, which is rotatably disposed within the outer casing 10. The UV sterilization module 60 is mounted on the filter screen support structure and located on one side of the filter screen 31, for UV sterilization of the filter screen 31. By setting the filter screen 31 as a rotatable cylindrical structure and placing the UV sterilization module 60 on one side, the entire outer surface of the rotating filter screen 31 can be uniformly irradiated 360 degrees without dead angles, ensuring thorough and efficient sterilization and effectively inhibiting bacterial growth.

[0100] In some embodiments, the ultraviolet sterilization module 60 includes a lamp holder 62 and an ultraviolet lamp 61. The lamp holder 62 extends along the length direction of the filter 31, and the extension length is not less than the length of the filter 31. There are multiple ultraviolet lamps 61, which are arranged at intervals along the length direction of the lamp holder 62, and the irradiation range of the multiple ultraviolet lamps 61 in the height direction of the filter covers the filter.

[0101] In the above embodiment, by setting the length of the lamp holder 62 to be no less than the length of the filter 31, and using multiple ultraviolet lamps 61 arranged at intervals along its length, the irradiation range of the multiple ultraviolet lamps 61 in the height direction of the filter covers the filter, ensuring that the ultraviolet light can cover the entire effective filtration height of the filter 31, avoiding the problem of incomplete sterilization in local areas of the filter due to insufficient irradiation length, ensuring that there are no dead corners in the longitudinal sterilization of the filter, and the interval arrangement of multiple lamp beads can form a continuous and uniform ultraviolet light field on the surface of the filter. Combined with the rotation of the filter, every point of the filter can receive a sufficient amount of ultraviolet radiation dose, thereby greatly improving the reliability and uniformity of sterilization.

[0102] In some embodiments, the filter support structure includes a bottom support component 33 and a top support component 32, and an intermediate support frame 34 disposed between the bottom support component 33 and the top support component 32. The bottom support component 33, the top support component 32 and the intermediate support frame 34 together enclose an installation space for accommodating the filter 31. The bottom support component 33 and the top support component 32 are respectively provided with axial mounting grooves. The two ends of the lamp holder 62 are respectively inserted into the axial mounting grooves of the bottom support component 33 and the top support component 32 and fixed by screws. In the above embodiments, by placing the lamp holder 62 within the axial mounting grooves on the bottom support component 33 and the top support component 32 respectively, it can be ensured that the lamp holder 62 and the filter are installed coaxially, reducing eccentricity. Furthermore, the two ends of the lamp holder 62 are first inserted into the axial mounting grooves for initial positioning, and then secured with screws, ensuring precise alignment and mechanical strength of the connection, preventing displacement due to vibration, and thus guaranteeing the stability of the sterilization effect of the ultraviolet sterilization module 60.

[0103] Specifically, the axial mounting groove on the bottom support component 33 is open at least on its top surface, and the axial mounting groove on the top support component 32 is open at least on its bottom surface. Preferably, the outer peripheral surfaces of the axial mounting grooves of the bottom support component 33 and the top support component 32 are also open. This design facilitates the installation and fixing of the lamp holder 62 by pushing it into the two axial mounting grooves from the openings on the outer peripheral side of the filter support structure after the filter support structure is assembled. More preferably, at least one axial mounting groove is provided with a positioning rib or a positioning groove, and the lamp holder 62 is provided with a corresponding positioning groove or positioning rib. Through the cooperation of the positioning rib and the positioning groove, the lamp holder 62 can be effectively prevented from tipping over after being pushed into the axial mounting groove, which facilitates subsequent screw driving.

[0104] In some specific embodiments, there are two intermediate support frames 34, which are arranged opposite to each other. The intermediate support frames 34 are frame-shaped, with the upper end of the frame-shaped intermediate support frame 34 connected and fixed to the top support assembly 32, and the lower end of the frame-shaped intermediate support frame 34 connected and fixed to the bottom support assembly 33. The lamp holder 62 is installed between the two intermediate support frames 34.

[0105] In some embodiments, the filter module 30 includes a filter screen 31 and a filter screen support structure, wherein a filter screen mounting space is formed within the filter screen support structure, and the filter screen 31 is rotatably mounted within the filter screen mounting space; the upper fan assembly 21 is detachably mounted above the filter screen support structure, and the lower fan assembly 22 is detachably mounted below the filter screen support structure.

[0106] In some embodiments, filter 31 is composed of at least a HEPA filter and an activated carbon filter.

[0107] In the above embodiments, the cylindrical filter 31 is designed to fit the air inlet 100 circumferentially surrounding the outer casing 10, resulting in a larger filtration area and the ability to handle a larger air volume within the same volume. It also provides a structural support for filter rotation and advanced maintenance functions such as filter self-cleaning and UV sterilization. Furthermore, the filter 31 employs a composite design of HEPA and activated carbon filters, which not only efficiently intercepts particulate matter but also adsorbs gaseous pollutants, achieving simultaneous and efficient removal of both major air pollutants. Specifically, the HEPA filter is located on the inner circumference of the activated carbon filter, and the filter 31 is detachably installed in the housing 10. By integrating the HEPA high-efficiency particulate air filter and the composite activated carbon filter into one unit, an independently replaceable cylindrical unit is formed and detachably installed in the housing 10, effectively solving the resource waste problem of traditional integrated filters that need to be replaced as a whole due to partial failure.

[0108] In some embodiments, the air purifier further includes a negative ion generator 214, which is mounted on the second bracket 213. The negative ion generator 214 can adsorb any residual particulate matter in the air passing through the upper air duct 212 by generating negative ions, thereby further purifying the air.

[0109] In some embodiments, the air purifier further includes a dust collection device 40, which is disposed on one side of the filter 31 and is used to clean the filter 31.

[0110] The air purifier proposed in this application mainly consists of a shell 10, an air inlet grille, a filter module 30, an ultraviolet sterilization module 60, a dust collection device 40, an upper fan assembly 21, and a lower fan assembly 22. This purifier employs a dual centrifugal fan system, with the two fans respectively placed in the upper air duct 212 and the lower air duct. An annular air inlet 100 is provided on the air inlet grille 11 of the shell 10, forming a purification method of central air intake and top and bottom air exhaust. After purification, part of the air is blown upwards by the upper fan assembly 21, and the other part is blown downwards by the lower fan assembly 22 and discharged from all sides, ultimately forming the following configuration: Figure 5 The diagram shows a "surrounding" airflow path. Compared to traditional top and bottom air intake and center air exhaust, this solution avoids the problem of dust or foreign objects being easily drawn in when air is drawn in from the ground, leading to filter clogging, performance degradation, and shortened lifespan. Furthermore, common center air exhaust designs tend to create a noticeable direct airflow sensation, which can easily disturb users in quiet environments such as sleeping or working. The surrounding airflow created by this solution, with center air intake and top and bottom air exhaust, effectively eliminates the discomfort of direct airflow, allowing users to enjoy uniformly flowing clean air without feeling any discomfort while achieving purification, thus enhancing the user experience.

[0111] Furthermore, a filter module 30 integrating a HEPA high-efficiency particulate air filter and a composite activated carbon filter is installed at the air inlet 100. The composite activated carbon filter is placed inside the HEPA filter, together forming a cylindrical, independently replaceable filter unit. This design allows users to easily replace the failed filter section individually, avoiding the need for complete replacement of traditional integrated composite filters due to partial failure, thereby reducing maintenance costs and resource waste. At the same time, the central air intake and top-bottom air outlet layout only requires a single filter in the middle of the unit, making filter replacement and cleaning more convenient. In contrast, if a top-bottom air intake and central air outlet design were used, two sets of pre-filters would need to be installed at the top and bottom air inlets, increasing maintenance complexity and costs.

[0112] Furthermore, the central air intake and top-to-bottom air outlet structure helps to expand the functions of the air purifier. To avoid filter clogging and bacterial accumulation due to centralized purification at the air inlet 100, which would affect its service life, this embodiment preferably employs filter self-cleaning technology and an ultraviolet sterilization module 60 to centrally maintain the central filter, achieving both self-cleaning and sterilization functions. In contrast, the top-to-bottom air intake and central air outlet structure, with its dispersed filter element arrangement at the air inlet 100, makes it difficult to achieve the aforementioned centralized maintenance function.

[0113] This embodiment utilizes a top support assembly 32 above the filter 31 and a bottom support assembly 33 below it to facilitate centralized maintenance of the air inlet 100 filter. The two support assemblies are connected by two intermediate support frames 34, which bear the main weight of the entire unit. The top support assembly 32 is driven by a stepper motor to rotate the filter 31, which is fixed and pre-tightened to it; the bottom support assembly 33 serves as a base, providing a platform for the filter 31 to rotate freely and support manual lifting.

[0114] Furthermore, this embodiment also includes a four-in-one sensor on the upper fan assembly 21 and a formaldehyde sensor 14 on the housing 10. The formaldehyde sensor 14 and the four-in-one sensor work together to monitor air quality in real time, enabling the purifier to dynamically adjust the purification mode according to different environments, thereby improving purification efficiency. Preferably, a cover plate 13 is provided on the back of the housing 10, and the formaldehyde sensor 14 is integrated on the cover plate 13. The top of the cover plate 13 is limited by the ribs on the side of the upper air duct 212, and the bottom of the cover plate 13 is fixed to the bottom of the filter top support assembly 32 by buckles and screws.

[0115] Furthermore, the air purifier also includes a support base 80, which supports the entire unit. The lower fan assembly 22 is connected to the bottom of the vacuum base by screws and clips, and fixed above the support base 80. The support base 80 is equipped with casters at the bottom, making it easy to move the purifier to different positions. The first bracket 222 is fixed to the top of the base by screws, and a bottom light assembly 90 is installed at its bottom by clips. The bottom light assembly 90 includes a light strip bracket 91 and a bottom ambient light strip 92. The bottom ambient light strip is embedded in the groove of the light strip bracket 91 and adopts an adjustable warm light design to avoid glare at night and optimize the user experience. The first fan 221 is installed inside the first bracket 222, and three flow openings 2220 are opened around its perimeter. Each flow opening 2220 has a specific slot for installing the deodorization module 50. The deodorization module 50 consists of three plasma generators 51, three metal mesh covers 52, and three ozone reduction meshes 53. It can efficiently decompose and neutralize TVOCs, odors, and other organic pollutants in the air passing through the lower air outlet 102. The plasma generators 51 produce high-density plasma, which catalyzes the degradation of harmful gases. The metal mesh covers 52 are located between the ozone reduction meshes 53 and the plasma generators 51, and are grounded to prevent plasma leakage. The outermost ozone reduction meshes 53 prevent excessive ozone from escaping due to glow discharge.

[0116] Furthermore, the upper fan assembly 21 is fixed above the top support assembly 32 with screws. The upper fan assembly 21 includes an upper air duct 212, a second bracket 213, and a second fan 211. The second fan 211 is installed below the second bracket 213, and a display module is installed above it. The display module includes an indicator light, a lampshade, a lamp holder 73, an air quality light 77, and a lamp frame. The air quality light 77 is embedded in the groove of the lamp frame and uses a ring-shaped LED matrix to dynamically display key indicators such as PM2.5 and formaldehyde in real time, allowing users to intuitively understand air quality and purification effects without the need for a screen or APP. A crystal lamp ball is mounted on the lamp holder 73, and a color display screen is integrated on its top for easy user operation of the entire unit. The crystal material forms a soft halo under the light, enhancing the product's visual style. In another embodiment, a lifting crystal lamp ball design can be adopted, which automatically rises when the unit is turned on and automatically lowers when it is turned off, enhancing aesthetics while giving users a sense of ritual in intelligent interaction.

[0117] Furthermore, to ensure the deodorization effect, the airflow through the deodorization module 50 needs to reach an appropriate air volume. When the purifier is in deodorization mode, the air volume at the lower air outlet 102 can be controlled by the first fan 221 to maintain an ideal air volume. At this time, the second fan 211 can still adjust the air volume at the upper air outlet 101 to continue purifying the air, thereby maximizing the purification performance and working efficiency of the whole machine in deodorization mode. When switching to normal purification mode, the deodorization module 50 can be turned off, and the speed of the two fans can be adjusted separately to achieve rapid purification.

[0118] The air purifier provided in this application expands its adaptability to multiple scenarios by integrating odor removal functionality. Based on the airflow path, it innovatively integrates a plasma generator 51, a metal mesh cover 52, and an ozone reduction mesh 53 to form an odor removal module 50. This module dynamically switches to odor removal mode according to environmental needs and works in conjunction with the first fan, automatically adjusting the airflow to optimal levels for efficient decomposition of TVOCs and odors. Simultaneously, the second fan maintains basic purification efficiency, achieving efficient and safe odor removal and significantly improving the device's applicability and user experience in odor-prone environments. While ensuring the air purifier's performance, this application expands its functionality and purification modes, enhancing its reliability and adaptability in various application scenarios to meet diverse user needs and improve the user experience.

[0119] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
