[0036] 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.

[0037] The following is for reference. Figures 1-8 An air handling apparatus 1 according to an embodiment of the present invention is described.

[0038] The air handling device 1 according to this application includes a main unit 11, an air duct assembly 12, a baffle assembly 14, and a movable plate 142. The air duct assembly 12 is rotatably connected to the main unit 11. The main unit 11 draws air into and exhausts air into the airflow handling chamber 110 inside it through the air duct assembly 12. The baffle assembly 14 is disposed on the air duct assembly 12 and is used to guide the airflow to the air intake 122 of the air duct assembly 12. The movable plate 142 is retractably disposed on the baffle assembly 14, and at least part of the edge of the movable plate 142 remains in elastic contact with the surface of the main unit 11.

[0039] In the embodiments of this application, an airflow processing chamber 110 and an exhaust port 1110 communicating with it are provided inside the main unit 11, forming an airflow passage for purifying or treating the intake airflow and discharging it. The air duct assembly 12 has an air duct 121 and an air intake 122 formed inside, which is rotatably mounted on the main unit 11. The air duct 121 and the airflow processing chamber 110 are always in communication, allowing the direction of the air intake 122 on the air duct assembly 12 to be flexibly adjusted, thereby meeting the air intake requirements of different directions and angles, significantly improving the convenience and adaptability of the air handling device 1. A guide vane assembly 14 is disposed on the air duct assembly 12, its main function being to guide the surrounding airflow more efficiently to the air intake 122. When the airflow flows towards the air intake 122, part of the airflow rushes towards the guide vane assembly 14, forming a wall adhesion effect, and then flows along the guide vane assembly 14 towards the air intake 122, preventing the airflow from escaping to the other side of the air intake 122.

[0040] In the embodiments of this application, the movable plate 142 is retractably disposed on the guide plate assembly 14, and at least a portion of the edge of the movable plate 142 always maintains elastic contact with the surface of the main unit 11. This allows the movable plate 142 to adaptively extend and retract with the rotation of the air duct assembly 12, effectively avoiding structural interference between the guide plate 14 and the main unit housing 111, and forming a dynamic sealing structure through continuous elastic contact. This sealing structure significantly reduces airflow leakage at the rotating connection, ensuring that the intake airflow is concentrated and enters the processing chamber 110 through the air duct 121, thereby improving exhaust efficiency and system energy efficiency, while also enhancing the stability and reliability of the device operation.

[0041] The air handling unit 1 of this application rotatably mounts the air duct assembly 12 onto the main unit 11, allowing for flexible adjustment of the direction of the air intake 122 to meet air intake requirements in different directions. Simultaneously, by providing a baffle assembly 14 on the air duct assembly 12, the air intake range of the air duct 121 is effectively expanded. Furthermore, the two switchable states of the baffle 14 prevent interference with surrounding structures when the air duct assembly 12 rotates, thereby improving air intake efficiency and operational freedom while ensuring the stability and reliability of the device's operation. Flexible seals 18 are provided on at least a portion of the edges of the movable plate 142 to maintain the sealing effect of the baffle assembly 14 and improve airflow efficiency.

[0042] The air handling device 1 of this application achieves multi-directional air intake through the rotatable air duct assembly 12, meeting the flexible air supply requirements; at the same time, the retractable movable plate 142 provided on the guide plate 14 can always maintain elastic contact with the surface of the main unit 11 when the air duct 121 rotates, which can not only adapt to the need for adjustment of the direction of the air intake 122 and dynamically avoid structural interference, but also further guide the airflow through the guide plate assembly 14 to prevent the airflow from escaping to the other side of the air intake 122.

[0043] According to some embodiments of this application, a receiving space 1410 is formed inside the deflector assembly 14. The receiving space 1410 is open on the side facing the host 11 and has a telescopic opening 1414. At least a portion of the movable plate 142 is received in the receiving space 1410 and extends out through the telescopic opening 1414.

[0044] The deflector assembly 14 has a receiving space 1410 inside, allowing the movable plate 142 to be partially received within the receiving space 1410 and extend out along the telescopic opening 1414. This not only provides storage space for the movable plate 142 but also serves as a stable guide for its movement, ensuring a reliable trajectory. When not in use, the movable plate 142 can be received within the receiving space 1410 for easy storage of the air handling unit 1, reducing its footprint. During use, it extends out through the telescopic opening 1414, maintaining elastic contact with the surface of the main unit 11, effectively reducing airflow leakage and avoiding structural interference.

[0045] According to some embodiments of this application, the deflector assembly 14 and the movable plate 142 are connected by an elastic member 17 to maintain the movable plate 142 in elastic contact with the surface of the host 11.

[0046] The baffle assembly 14 and the movable plate 142 are connected by an elastic element 17, which continuously provides an elastic force to move the movable plate 142 toward the surface of the main unit 11, thereby maintaining the elastic contact between the movable plate 142 and the main unit housing 111. The elastic element 17 not only enables adaptive adjustment of the contact pressure between the movable plate 142 and the main unit 11 during the rotation of the air duct assembly 12, but also effectively compensates for assembly tolerances and motion wear, and further ensures dynamic sealing at different rotation angles of the air duct assembly 12, significantly reducing air leakage, improving the air intake efficiency of the air duct assembly 12, and enhancing the stability and durability of the system operation.

[0047] According to some embodiments of this application, a first guide member 151 is provided on the movable plate 142, and a second guide member 152 is provided inside the flow deflector assembly 14; wherein the first guide member 151 and the second guide member 152 cooperate with each other and restrict the movable plate 142 from moving relative to the flow deflector assembly 14 in the direction toward the host 11, and an elastic member 17 is disposed between the first guide member 151 and the second guide member 152.

[0048] By having the first guide 151 on the movable plate 142 cooperate with the second guide 152 inside the baffle assembly 14, the movable plate 142 is effectively restricted to moving only in the direction toward the host 11, thus ensuring the accuracy and stability of its telescopic movement.

[0049] By placing the elastic element 17 between the first guide element 151 and the second guide element 152, it can be ensured that the elastic force direction of the elastic element 17 is consistent with the relative movement direction between the first guide element 151 and the second guide element 152. This ensures that the elastic element 17 continuously provides uniform elastic force, guaranteeing that the movable plate 142 and the surface of the host 11 always maintain a stable elastic contact effect, thereby further enhancing the dynamic seal. In addition, the cooperation between the first guide element 151 and the second guide element 152 can also reduce the skewing, jamming and abnormal wear of the movable plate 142 during its movement, improving the smoothness of the movement and the service life of the movable plate 142.

[0050] According to some embodiments of this application, the first guide member 151 is constructed as a guide post extending in the telescopic direction of the movable plate 142, and the second guide member 152 has a guide hole 1521 formed on it to cooperate with the guide post. The guide post can be inserted into the guide hole 1521. The cooperation between the guide post and the guide hole 1521 provides stable guidance for the telescopic movement of the movable plate 142, effectively limiting the radial offset or wobbling of the movable plate 142 in the guide hole 1521, ensuring that the movable plate 142 and the surface of the main unit 11 are always aligned, and avoiding abnormal wear and friction noise of the movable plate 142 during movement, while enhancing the overall structural stability and service life.

[0051] According to some embodiments of this application, the movable plate 142 has a protruding base 1421 on one side in the thickness direction, and a mounting surface 1422 is formed on the base 1421. The mounting surface 1422 is orthogonal to the extension direction of the movable plate 142 and a guide post is provided on the mounting surface 1422. The two ends of the elastic member 17 abut against the mounting surface 1422 and the second guide member 152.

[0052] By forming a protruding base 1421 on one side of the movable plate 142 in the thickness direction, and the mounting surface 1422 provided on the base 1421 being orthogonal to the extension direction of the movable plate 142, the mounting surface 1422 can serve as the mounting base for the guide column to maintain the stable connection between the guide column and the movable plate 142. The two ends of the elastic member 17 abut against the mounting surface 1422 and the second guide member 152. By abutting the two ends of the elastic member 17 against the mounting surface 1422 and the second guide member 152 respectively, not only is a stable and uniform force application plane provided for the elastic member 17, but it can also ensure that the movable plate 142 is always subjected to an elastic abutment force perpendicular to the mounting surface 1422. The integrated design of the base 1421 and the guide column optimizes the load distribution of the elastic force on the movable plate 142, reduces local stress, and significantly improves the smoothness of the movement and the guiding accuracy of the movable plate 142.

[0053] According to some embodiments of this application, the deflector assembly 14 includes a front side plate 1411 and a rear side plate 1412, with at least a partial gap between the front side plate 1411 and the rear side plate 1412 to form a receiving space 1410. A telescopic opening 1414 is formed between the bottom of the front side plate 1411 and the bottom of the rear side plate 1412. A bottom sealing plate 1413 extending toward the movable plate 142 is formed at the bottom of the front side plate 1411 and / or the bottom of the rear side plate 1412. The bottom sealing plate 1413 abuts against the surface of the movable plate 142.

[0054] The bottom sealing plate 1413 abuts against the surface of the movable plate 142, effectively sealing the receiving space 1410. This prevents airflow from entering the receiving space 1410, ensuring the sealing performance and flow guiding efficiency of the guide plate assembly 14. Simultaneously, the bottom sealing plate 1413 also limits the movement direction of the movable plate 142, helping to reduce the size of the telescopic opening 1414. The bottom sealing plate 1413 also provides a foundation for the internal guide structure, further enhancing the stability and reliability of the device operation.

[0055] According to some embodiments of this application, the front side panel 1411 or the rear side panel 1412 has side panels 1415 formed on both sides in the width direction. The width of the side panel 1415 is reduced in the portion facing the telescopic opening 1414 to form a clearance notch 1416. The clearance notch 1416 is adapted to avoid the movable panel 142 when the movable panel 142 is retracted into the receiving space 1410. In the width direction of the deflector assembly 14, a side plate 1415 is provided to further close the two sides of the front side plate 1411 or the rear side plate 1412 in the width direction, thereby forming a complete receiving space 1410. A clearance notch 1416 is formed in the part of the side plate 1415 facing the telescopic opening 1414 by reducing the width. When the movable plate 142 performs telescopic movement and retracts into the receiving space 1410, the clearance notch 1416 can provide clearance space for the movement of the movable plate 142, preventing movement interference between the movable plate 142 and the side plate 1415. At the same time, it can also limit the movement trajectory of the movable plate 142 in the thickness direction, thereby ensuring the smoothness and stability of the telescopic process of the movable plate 142 and improving the reliability of the movement of the movable plate 142.

[0056] According to some embodiments of this application, at least one of the front side plate 1411 and the rear side plate 1412 has a fixing protrusion 161 formed thereon, and at least one of the front side plate 1411 and the rear side plate 1412 has a mounting hole 162 that mates with the fixing protrusion 161. A threaded hole may be provided inside the fixing protrusion 161, and the mounting hole 162 may be used for a fastener to pass through. The fastener and the fixing protrusion 161 are used to fix the front side plate 1411 and the rear side plate 1412. In some embodiments, the fixing protrusion 161 and the mounting hole 162 may also employ a snap-fit ​​engagement or other limiting methods, not limited to a threaded engagement. By providing the fixing protrusion 161 and the positioning hole 162, the front side plate 1411 and the rear side plate 1412 can be connected to maintain a consistent distance between them, ensuring the structural reliability and stability of the movable plate 142 assembly.

[0057] According to some embodiments of this application, the air duct assembly 12 is constructed as an annular shape with a notch, and the air duct assembly 12 has an air outlet 123 at at least one end of the notch and is rotatably connected to the host 11.

[0058] In some embodiments, the air duct assembly 12 is U-shaped, with a cavity between the two vertically arranged portions of the U-shaped structure. A notch is formed at the bottom of the air duct assembly 12, and the air intake 122 is arranged along the contour of the air duct assembly 12. When the main unit 11 is running, a negative pressure is formed at the air intake 122 of the air duct assembly 12, causing airflow to flow towards the air intake 122. To prevent airflow from passing between the two vertically arranged portions of the U-shaped structure and causing oil fumes to escape, a guide vane assembly 14 is arranged between the two vertically arranged portions of the U-shaped structure. Thus, when the airflow flows towards the air intake 122, some of the airflow hits the guide vane assembly 14 and then flows along the guide vane assembly 14 towards the air intake 122, preventing the airflow flowing towards the air intake 122 from flowing through the cavity between the two vertically arranged portions of the U-shaped structure to the other side of the air duct assembly 12.

[0059] Since the air duct assembly 12 can rotate around the main unit 11, so that the air duct assembly 12 is tilted relative to the vertical plane, or when the air handling unit 1 needs to be stored, the air duct assembly 12 needs to be rotated 180° relative to the main unit 11; when the air duct assembly 12 rotates, in order to avoid interference between the guide plate assembly 14 and the main unit 11, there are two solutions. The first solution is that there is a gap between the lower edge of the guide plate assembly 14 and the upper surface of the main unit 11, so that when the air duct assembly 12 rotates around the main unit 11 and forms an angle in the vertical direction, the guide plate assembly 14 will not interfere with the main unit 11; the second solution is that the lower end of the guide plate assembly 14 can rise or fall relative to the main unit 11. When the position of the air duct assembly 12 is fixed, the lower edge of the guide plate assembly 14 contacts the upper surface of the main unit 11. When the air duct assembly 12 needs to be rotated, the lower end of the guide plate assembly 14 rises relative to the upper surface of the main unit 11.

[0060] In some embodiments of this application, the air intake 122 of the air duct assembly 12 is configured to form a slit on the inner edge of the air duct assembly 12, so that the air intake 122 is configured as an air inlet gap. The slit-type air inlet 122 increases the air intake pressure of the air intake 122 by reducing the air inlet area, thereby enhancing the air intake effect of the air duct assembly 12 and improving the purification capacity of the air handling device 1 according to this application.

[0061] According to some embodiments of this application, the main unit 11 is provided with an air duct shell 112 inside, the upper part of the air duct shell 112 is a top shell 1122, and the lower part is a bottom shell 1121. According to some embodiments of this application, the main unit 11 includes: a main unit shell 111, an airflow processing chamber 110 is formed inside the main unit shell 111, and an exhaust hole 1110 communicating with the airflow processing chamber 110 is provided at the rear of the main unit shell 111; a fan module, the fan module is disposed inside the main unit shell 111, and a top shell 1122 is provided on the fan module, the top shell 1122 forms an air inlet channel, and a filter component is disposed in the air inlet channel.

[0062] 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.

[0063] According to some embodiments of this application, the wind turbine 113 includes: a wheel disk 1131, which is disposed at the bottom of the wind turbine cavity and is used to connect with the drive component 114; multiple blades 1132, which are disposed at intervals on the outer periphery of the wheel disk 1131; and a wheel cover 1133, which is annular and disposed on the top of the multiple blades 1132 and connects the multiple blades 1132.

[0064] 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.

[0065] 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.

[0066] According to some embodiments of this application, the purification device includes: a negative ion generator disposed in the airflow treatment chamber 110 and used to generate negative ions; and / or an ozone generator disposed in the airflow treatment chamber 110 and used to generate ozone.

[0067] 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.

[0068] According to some embodiments of this application, mating holes 1111 for connecting the air duct assembly 12 are formed on the two side walls of the main housing 111 facing each other. The mating holes 1111 are used to connect the air outlet 123 of the air duct 121. The air duct assembly 12 has extension sections 124 extending into the mating holes 1111 at both ends of the disconnection point. A sealing element 125 is provided between the outer periphery of the extension section 124 and the inner wall of the mating hole 1111.

[0069] According to the technical solution of this application, the main housing 111 adopts a symmetrical connection structure, and dedicated mating holes 1111 are respectively provided on the two opposite side walls of the main housing 111 for docking with the air duct assembly 12. The size and shape of the mating holes 1111 match the air outlet 123 of the air duct 121 to ensure the sealing of the airflow channel. The extension sections 124 provided at both ends of the air duct assembly 12 adopt an insertion structure and can be embedded into the mating holes 1111 of the main housing 111 to form a stable mechanical connection. The annular sealing element 125 provided between the extension section 124 and the mating hole 1111 is made of elastic material, which ensures airtightness while allowing a certain installation tolerance.

[0070] In this embodiment, the extension 124 ensures accurate positioning, and the seal 125 eliminates airflow leakage, allowing the duct assembly 12 to flexibly select the connection position and ensuring the sealing performance of the entire airflow channel. This enables the duct housing 112 of this application to achieve both convenient installation and efficient sealing without requiring complex assembly processes, significantly improving the overall performance and ease of use of the air handling unit 1.
