[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is for reference. Figures 1-4 An air handling apparatus according to an embodiment of the present invention is described.

[0030] According to one embodiment of this application, the air handling device 1 includes: a main unit 11 and a first cover plate 14. The main unit 11 is provided with an airflow handling chamber 110 inside. The main unit 11 is provided with an open opening and an exhaust hole 1110 communicating with the airflow handling chamber 110. The airflow handling chamber 110 is provided with a purification module and a fan module for purifying airflow. The first cover plate 14 is used to cover the open opening. The first cover plate 14 is provided with a top air passage 141 and communicates the airflow handling chamber 110 with the outside.

[0031] In this application, the air handling unit 1 forms a closed whole through the combination of the main unit 11 and the first cover plate 14. The airflow processing chamber 110 inside the main unit 11 houses functional modules for filtering or purifying the airflow entering the main unit 11. After the indoor flue gas enters the main unit 11, it is introduced into the main unit 11 through the top air duct 141, thereby purifying the airflow. The combination of the first cover plate 14 and the main unit 11 optimizes the airflow path, allowing the airflow to directly enter the main unit 11, thereby improving the airflow rate.

[0032] In addition, the top opening of the main unit 11 and the exhaust hole 1110 together form a directional airflow channel for air intake from the top. The purification module in the channel purifies the air, while the fan module actively drives the airflow, improving the processing efficiency. This makes the overall structure and function of the air handling unit 1 clear and contributes to the overall compact layout of the air handling unit 1.

[0033] The first cover plate 14 is not only used to cover the open opening to seal the airflow processing chamber 110, protect the internal purification module and fan module and reduce operating noise, but also the top air duct 141 integrated on it enables communication with the external environment, simplifies the overall structure, and enables the air handling device 1 to achieve efficient, stable and low-noise air purification function in a compact space.

[0034] According to the embodiment of this application, the air handling device 1, through the combination of the main unit 11 and the first cover plate 14, effectively solves the problem of purifying cooking fumes during indoor cooking. The airflow processing chamber 110 inside the main unit 11 houses the purification module and the fan module, constituting the main functional components for efficient purification of polluted air. While the first cover plate 14 closes the opening of the main unit 11, its top air duct 141 connects the airflow processing chamber 110 with the indoor environment. This allows the air handling device 1 to effectively collect indoor fumes from the cooking area. Since the top air duct 141 is directly driven by the fan module, it significantly improves the device's suction capacity and overall purification flow rate, thereby effectively preventing the accumulation of cooking fumes indoors and greatly improving indoor air quality.

[0035] According to some embodiments of this application, in the airflow processing chamber 110, the purification module and the fan module are arranged sequentially along the air intake direction, the top air duct 141 connects the external air and the purification module, and the purification module connects the top air duct 141 and the fan module.

[0036] The air handling unit 1 forms a smooth airflow path by sequentially arranging the purification module and the fan module along the air intake direction within the airflow treatment chamber 110. The air is first purified before passing through and being discharged from the fan module. The air entering the fan module is purified air, which reduces smoke pollution to the fan module and extends its service life. Furthermore, during operation, the air in the operating environment circulates between the air handling unit and the operating environment. Air drawn in by the air extraction device is still discharged into the operating environment. After air enters the purification module and is then passed through it to the fan module, the air discharged from the fan module is also purified air, thus purifying the air in the operating environment and improving air quality.

[0037] The top air duct 141 serves as the inlet for external air and is directly connected to the purification module. This ensures that all untreated air is purified first, avoiding airflow bypass and guaranteeing purification effectiveness while minimizing pressure loss. The design connecting the purification module to the top air duct 141 and the fan module allows the purified air to be actively drawn in and rapidly discharged by the fan module, further enhancing airflow dynamics and preventing secondary contamination of the purified air within the air handling chamber 110. This improves the purification speed, efficiency, and reliability of the air handling unit 1.

[0038] According to some embodiments of this application, the air inlet side of the purification module and the open opening have a height difference in the height direction. The length of the top air duct 141 is adapted to the height difference. The top air duct 141 is constructed as an annular wall 142 disposed on the lower surface of the first cover plate 14. The annular wall 142 extends into the airflow processing chamber 110 and communicates with the filter module.

[0039] According to some embodiments of this application, the air inlet side of the purification module and the open end have a height difference in the vertical direction. The length of the top air duct 141 is adapted to the height difference, and external air directly enters the purification module through the top air duct 141. Untreated airflow will not enter other spaces within the cavity of the main unit 11, thus preventing untreated oil fumes from polluting the cavity of the main unit. The top air duct 141 is constructed as an annular wall 142 disposed on the lower surface of the first cover plate 14. This annular wall 142, as a structural extension, can effectively guide and seal the airflow, ensuring that all externally entering air is directed to the purification module, avoiding airflow leakage, thereby significantly improving purification efficiency.

[0040] According to some embodiments of this application, a protruding ridge 143 is formed on the first cover plate 14, the ridge 143 defines a top air passage 141, and an air inlet 1431 of the top air passage 141 is provided on the front side of the ridge 143.

[0041] A raised portion 143 is formed on the first cover plate 14. The shape design of the raised portion 143 helps to guide and converge external airflow, expanding the air intake range. The raised portion 143 provides more space for the top air passage 141. The raised portion 143 internally defines the top air passage 141, realizing an integrated structure of the air passage and the cover plate, saving materials and internal space of the main unit 11, and increasing the air intake volume per unit time by increasing the cross-sectional area of ​​the air passage to reduce airflow resistance.

[0042] An air inlet 1431 with a top air passage 141 is provided on the front side of the raised portion 143. The air inlet 143 is fully utilized by the airflow guiding shape of the raised portion 143, which can capture the airflow in front more efficiently, reduce the dead zone of airflow intake, and optimize the intake efficiency. As an integrated aerodynamic shell, the raised portion 143 not only expands the air intake coverage and air passage volume, but also achieves directional and efficient air capture through the front air inlet 1431. The overall structure significantly improves the intake capacity and flow field efficiency within a limited space, thereby enhancing the airflow handling efficiency of the air handling device 1.

[0043] According to some embodiments of this application, the top of the host 11 is provided with an opening, the edge of the opening is formed with a limiting notch 1101, and the edge of the first cover plate 14 is provided with a first limiting protrusion 144 that cooperates with the limiting notch 1101.

[0044] The top of the main unit 11 has an open opening to facilitate the installation, maintenance, and cleaning of internal modules, while also providing a direct inlet and outlet channel for airflow. A limiting notch 1101 is formed at the edge of the open opening. The limiting notch 1101 provides a positioning reference for the first cover plate 14 and can be used to restrict the horizontal movement of the first cover plate 14, ensuring the accuracy of its installation position. Furthermore, the limiting notch 1101 also has a foolproof effect, preventing the installation orientation of the first cover plate 14 from being mismatched with that of the main unit 11.

[0045] In the embodiments of this application, the cover plate is easy to open and close. The edge of the first cover plate 14 is provided with a first limiting protrusion 144 that cooperates with the limiting notch 1101. Through the cooperation of the protrusion and the notch, fast and accurate pre-positioning is achieved, effectively preventing the first cover plate 14 from being misaligned or sliding during installation or operation.

[0046] According to some embodiments of this application, the host 11 includes: a host 11 housing, an airflow processing chamber 110 is formed inside the host 11 housing, and an exhaust hole 1110 communicating with the airflow processing chamber 110 is provided at the rear of the host 11 housing; a fan module, the fan module is disposed inside the host 11 housing, a top housing 1122 is provided on the fan module, the top housing 1122 forms an air inlet channel, and a filter component is disposed in the air inlet channel.

[0047] In some embodiments, the filter assembly is configured as a filter screen 1123 disposed in the air inlet channel. In addition, the filter assembly may also include a rigid filter element 131 disposed at the top of the air inlet channel.

[0048] In this application, the main unit 11 adopts a modular structure design, mainly composed of the main unit 11 housing and the fan module. The main unit 11 housing serves as the main frame of the device, and its internal space is constructed as a dedicated airflow processing chamber 110 to house the purification device and perform air processing. A specially designed exhaust port 1110 at the rear of the housing directly communicates with the airflow processing chamber 110, forming a discharge channel for purified air. The fan module, as the power core, is integrated within the main unit 11 housing. The top housing 1122 of the fan module is designed with an air inlet channel, within which a filter assembly is directly installed to form an intake filtration system.

[0049] The fan module draws in air through the air inlet channel of the top housing 1122. After preliminary filtration, the air is sent to the airflow treatment chamber 110 for deep purification and finally discharged through the exhaust port 1110 at the rear of the main unit housing 11. The airflow path of the air handling device 1 is reasonable, forming a complete flow path in air intake, treatment and exhaust. The filter components are directly integrated into the air intake channel of the fan module, which saves space and improves filtration efficiency. The rear exhaust port 1110 is designed to facilitate the directional discharge of purified air, realizing high-efficiency air handling capability in a compact layout.

[0050] According to some embodiments of this application, a fan module has a fan wheel cavity for accommodating the fan. The fan module also includes a guide ring 1134, which is disposed at the inlet of the fan wheel cavity. At least a portion of the guide ring 1134 extends into the fan wheel cavity, and the cross-sectional structure of the guide ring 1134 in the extending direction is an arc shape convex towards the top.

[0051] According to the fan module of this application, a flow guiding structure is provided at the top, and a fan wheel cavity is provided inside the fan module to provide space for fan operation. A guide ring 1134 is installed at the inlet of the fan wheel cavity. A portion of the guide ring 1134 extends into the fan wheel cavity, and the cross-section of the extended section adopts an upwardly convex arc shape, thereby reducing the resistance of the airflow entering the fan wheel cavity and providing a guiding effect, reducing the kinetic energy loss of the airflow during flow. The extended design of the guide ring 1134 effectively guides the airflow smoothly into the fan wheel cavity, avoiding turbulence and forming a local negative pressure zone during air intake, significantly improving intake efficiency.

[0052] In this embodiment, the impeller cavity provides a stable operating space for the fan, the air guide ring 1134 optimizes the airflow path, and the arc-shaped cross-section enhances the air intake effect, so that the fan module achieves a lower noise level and a higher air volume output while maintaining a compact structure.

[0053] According to some embodiments of this application, the wind turbine 113 includes: a disk 1131, a disk 1131 and blades 1132. The disk 1131 is disposed at the bottom of the wind turbine cavity and is used to connect with the drive component 114. Multiple blades 1132 are configured, and multiple blades 1132 are respectively disposed at intervals on the outer periphery of the disk 1131. A wheel cover 1133 is constructed in annular shape and is disposed on the top of the multiple blades 1132 and connects the multiple blades 1132.

[0054] In the technical solution of this application, the wind turbine 113 consists of three components: a rotor 1131, blades 1132, and a cover 1133. The rotor 1131 is fixed to the bottom of the wind turbine cavity as a basic load-bearing component. The center of the rotor 1131 is directly connected to the drive component 114 to realize power transmission. Multiple blades 1132 are arranged radially and evenly along the outer periphery of the rotor 1131. Each blade 1132 is inclined in a direction away from the center of the circle, so that after the rotor 1131 rotates, it drives the airflow to flow out radially, realizing axial air intake and radial air exhaust. The cover 1133 adopts a ring structure to cover the top of the blades 1132, connecting multiple blades 1132 into a whole.

[0055] The bottom positioning design of the impeller 1131 lowers the center of gravity of the impeller 113, improving operational stability; the evenly distributed multi-blade 1132 ensures the smoothness and consistency of airflow output; the top cover 1133 not only enhances the structural strength of the blades 1132 but also forms a complete airflow guiding surface. The blades 1132 generate directional airflow, and the cover 1133 strengthens the structure and optimizes the flow field, enabling the impeller 113 to maintain both aerodynamic performance and good mechanical stability at high speeds, providing a reliable airflow power source for the air handling unit 1.

[0056] According to some embodiments of this application, the fan module includes a bottom housing 1121 and a top housing 1122. The bottom housing 1121 has a fan cavity for accommodating the fan wheel 113. The bottom housing 1121 is open to the top to form the fan cavity inlet. The outer periphery of the bottom housing 1121 communicates with the exhaust hole 1110. The top housing 1122 is disposed on the top of the bottom housing 1121. The top housing 1122 defines an air inlet channel that extends to the fan cavity inlet. The purification module is disposed at the inlet of the air inlet channel.

[0057] According to some embodiments of this application, the fan module includes a bottom housing 1121. The impeller cavity formed inside the bottom housing 1121 provides operating space for the impeller 113, ensuring stable airflow generation. The bottom housing 1121 opens towards the top, forming the impeller cavity inlet, realizing an axial air intake flow channel design, which helps reduce intake resistance and improve fan efficiency. The outer periphery of the bottom housing 1121 communicates with the exhaust port 1110, forming a radial or tangential exhaust path, achieving separation of intake and exhaust airflow, and controlling the air pressure and volume of the airflow channel.

[0058] The top housing 1122 is located on top of the bottom housing 1121 and is used to connect the top housing 1122 to the opening, protect the internal impeller 113, and guide airflow. The top housing 1122 defines an air inlet channel that extends to the inlet of the impeller cavity. The purification module is located at the inlet of the air inlet channel to ensure that all air entering the fan is purified first, preventing unpurified air from directly entering the fan and subsequent space.

[0059] In some embodiments, the top housing 1122 and the bottom housing 1121 can be constructed as an integral housing. Constructing it as an integral housing can improve the overall structural strength, enhance the overall sealing performance, and reduce assembly steps, thereby effectively reducing the risk of leakage. In other embodiments, the top housing 1122 and the bottom housing 1121 can also be constructed as separate housings, which facilitates mold manufacturing, internal cleaning and maintenance, and replacement and repair of the impeller 113, thereby improving the maintainability and service life of the module.

[0060] According to some embodiments of this application, the purification device includes: a negative ion generator and / or an ozone generator, wherein the negative ion generator is disposed in the airflow treatment chamber 110 and is used to generate negative ions; and the ozone generator is disposed in the airflow treatment chamber 110 and is used to generate ozone.

[0061] In the technical solution of this application, the purification device adopts active air purification technology. At least one purification module is integrated in the airflow processing chamber 110. The negative ion generator generates a large number of negative ions through the high voltage discharge principle. These charged particles can effectively adsorb particulate pollutants in the air. The ozone generator uses ultraviolet light of a specific wavelength or corona discharge to generate ozone molecules, which oxidize and decompose organic pollutants and microorganisms.

[0062] Negative ion generators and ozone generators can work independently or in tandem, forming a complementary effect through different purification mechanisms: negative ions mainly target suspended particulate matter, while ozone focuses on the removal of gaseous pollutants and microorganisms.

[0063] The purification device of this application requires no consumables during the negative ion purification process and can operate continuously; ozone sterilization is fast and efficient, especially suitable for microbial contamination; the combined use of the two technologies can expand the purification range and improve the overall treatment effect. The negative ion generator and the ozone generator work together, enabling the air handling unit 1 to deal with different types of pollutants, achieving a more comprehensive air purification effect, while providing users with flexible and selectable purification modes to meet diverse usage needs.
