[0001] This invention relates to the field of air treatment, and more particularly to an air treatment device. Background Technology

[0002] In related technologies, the air duct assembly installed on the air handling unit is used to draw in airflow; however, relying solely on the air duct assembly itself results in poor airflow efficiency and limited airflow range. Adding auxiliary air guiding devices may impair the function of the air duct assembly. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide an air handling device, which is provided with a rotatable air duct assembly to meet the air intake requirements in different directions, and a deflector assembly to expand the air intake range of the air duct assembly. The deflector assembly itself has two switchable states, thereby avoiding interference between the air duct assembly and the air duct assembly during rotation.

[0004] The air handling device according to this application includes a main unit, an air duct assembly, and a baffle assembly. The main unit has an airflow handling chamber and an exhaust port communicating with the airflow handling chamber. The air duct assembly has an air duct and an air intake communicating with the air duct. The air duct assembly is rotatably mounted on the main unit, and the air duct is communicating with the airflow handling chamber. The baffle assembly is mounted on the air duct assembly and is used to guide the airflow toward the air intake.

[0005] The air handling unit of this application rotatably mounts the air duct assembly on the main unit, allowing for flexible adjustment of the air intake direction to meet air intake requirements from different directions. Simultaneously, by installing a baffle assembly on the air duct assembly, the air intake range of the air duct is effectively expanded. Furthermore, the baffle's switchable two states prevent interference with surrounding structures when the air duct assembly rotates, thereby improving air intake efficiency and operational freedom while ensuring the stability and reliability of the unit's operation.

[0006] According to some embodiments of this application, the deflector assembly has a switchable first state and a second state. In the first state, the deflector assembly extends toward the host to reduce or close the gap between the air duct assembly and the host. In the second state, the deflector assembly retracts toward the direction away from the host and is spaced apart from the host to form a clearance space to avoid interfering with the rotation of the air duct assembly relative to the host.

[0007] According to some embodiments of this application, the deflector assembly includes: a deflector body and a movable plate. The deflector body is fixedly connected to the air duct assembly, and the movable plate is movably disposed on the deflector body to switch between a first state and a second state. The movable plate can be translated relative to the deflector body or rotatably connected to the deflector body.

[0008] According to some embodiments of this application, a flexible seal is formed on the edge of the active plate facing the host.

[0009] According to some embodiments of this application, a receiving space is formed inside the main body of the guide plate, and at least a portion of the movable plate is disposed within the receiving space.

[0010] According to some embodiments of this application, a driving component is provided in the receiving space, and a guide component that cooperates with the driving component is provided on the movable plate. Under the drive of the driving component, the movable plate can selectively translate relative to the guide plate body in a direction closer to or farther from the host.

[0011] According to some embodiments of this application, the driving component is configured as a gear rotatably disposed within the receiving space, and the guiding component is configured as a rack extending in the translational direction of the movable plate, the rack cooperating with the gear to drive the movable plate to translate.

[0012] According to some embodiments of this application, the receiving space is provided with an outlet suitable for the movable plate to extend out, and the front and / or rear edges of the outlet are formed with a bottom sealing plate that extends in the front-rear direction and abuts against the movable plate.

[0013] According to some embodiments of this application, a guide groove extending in the translational direction is formed on the movable plate, and a guide protrusion is formed on the main body of the guide plate. The guide protrusion is received in the guide groove and limits the movement trajectory of the movable plate during the translation of the movable plate.

[0014] According to some embodiments of this application, the main body of the guide plate and the movable plate are respectively provided with a first limiting component and a second limiting component. One of the first limiting component and the second limiting component is a limiting protrusion, and the other of the first limiting component and the second limiting component is a plurality of limiting grooves arranged sequentially in the translational direction of the movable plate. The limiting protrusion can be selectively matched with any one of the limiting grooves to restrict the movement of the movable plate relative to the main body of the guide plate.

[0038] 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.

[0039] The following is for reference. Figures 1-7 An air handling apparatus according to an embodiment of the present invention is described.

[0040] The air handling apparatus according to this application includes a main unit 11, an air duct assembly 12, and a baffle assembly 14. The main unit 11 is provided with an airflow handling chamber 110 and an exhaust port 1110 communicating with the airflow handling chamber 110. The air duct assembly 12 is provided with an air duct 121 and an air intake communicating with the air duct 121. The air duct assembly 12 is rotatably disposed on the main unit 11, and the air duct 121 is communicating with the airflow handling chamber 110. The baffle assembly 14 is disposed on the air duct assembly 12 and is used to guide the airflow to the air intake.

[0041] 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 port 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 port 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. A guide vane assembly 14 is disposed on the air duct assembly 12, and its main function is to guide the surrounding airflow more efficiently to the air intake port. The guide vane assembly 14 can be used to expand the range of air intake action of the air duct assembly 12, improving the air intake efficiency of the air duct assembly 12.

[0042] In the illustrated embodiment, the air duct assembly 12 is U-shaped, with a cavity between the two vertically arranged sections of the U-shape. The air intake 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 of the air duct assembly 12, causing airflow to flow towards the air intake. To prevent airflow from passing between the two vertically arranged sections of the U-shape and causing oil fumes to escape, a guide vane assembly 14 is arranged between the two vertically arranged sections of the U-shape. Thus, when the airflow flows towards the air intake, some of the airflow hits the guide vane assembly 14 and then flows along the guide vane assembly 14 towards the air intake, preventing the airflow flowing towards the air intake from flowing through the cavity between the two vertically arranged sections of the U-shape to the other side of the air duct assembly 12.

[0043] Since the air duct assembly 12 can rotate around the main unit 11, allowing it to tilt relative to the vertical plane, or when the air handling unit needs to be stored, the air duct assembly 12 needs to be rotated 180° relative to the main unit 11; to avoid interference between the air guide plate assembly 14 and the main unit 11 when the air duct assembly 12 rotates, there are two solutions, such as... Figure 7 As shown, in one method, there is a gap between the lower edge of the baffle assembly 14 and the upper surface of the main unit 11. This ensures that when the air duct assembly 12 rotates around the main unit 11 and forms an angle in the vertical direction, the baffle assembly 14 will not interfere with the main unit 11. Figures 1 to 6 As shown, in the second method, the lower end of the guide plate assembly 14 can rise or fall relative to the host 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 host 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 host 11.

[0044] Furthermore, the rotatable characteristics of the air duct assembly 12, combined with the airflow guiding effect of the baffle, not only ensure a wide range of suction efficiency when dynamically adjusting the suction direction, but also the baffle assembly 14 itself is designed with two switchable states, ensuring that the baffle will not mechanically interfere with the main unit 11 or other components during the entire rotation of the air duct assembly 12, thereby ensuring the reliability of the device operation while achieving all-round suction.

[0045] The air handling device of this application rotatably mounts the air duct assembly 12 onto the main unit 11, allowing for flexible adjustment of the air intake direction to meet air intake requirements in different directions. At the same time, by mounting the baffle assembly 14 on the air duct assembly 12, the air intake range of the air duct 121 is effectively expanded. Furthermore, by utilizing the two switchable states of the baffle itself, interference between the air duct assembly 12 and the surrounding structure is avoided when it rotates. This improves air intake efficiency and operational freedom while ensuring the stability and reliability of the device's operation.

[0046] According to some embodiments of this application, the deflector assembly 14 has a switchable first state and a second state. In the first state, the deflector assembly 14 extends toward the host 11 to reduce or close the gap between the air duct assembly 12 and the host 11. In the second state, the deflector assembly 14 retracts toward the direction away from the host 11 and is spaced apart from the host 11 to form a clearance space to avoid interfering with the rotation of the air duct assembly 12 relative to the host 11.

[0047] The deflector assembly 14 can switch between a first state and a second state by deforming itself or moving relative to the air duct assembly 12. In the first state, the deflector assembly 14 extends toward the main unit 11 to reduce or completely close the gap between the air duct assembly 12 and the main unit 11, thereby preventing airflow leakage from the gap between the deflector assembly 14 and the main unit 11, improving suction efficiency, and enhancing the overall aesthetics of the air handling unit. In the second state, the deflector assembly 14 retracts away from the main unit 11, creating a specific clearance space between it and the main unit 11. When the air duct assembly 12 needs to be rotated to adjust its angle, the deflector assembly 14 actively moves to avoid collision or interference between the deflector assembly 14 and the structure of the main unit 11 when the air duct assembly 12 rotates, thereby ensuring the smoothness and reliability of the rotation function.

[0048] The two switchable first and second states make the baffle assembly 14 no longer a fixed structure, but a part that can be dynamically adjusted according to the movement requirements of the air duct assembly 12. When efficient air intake is required, it is in the first state to ensure airtightness and airflow efficiency; when the air duct assembly 12 needs to rotate, it can switch to the second state to prioritize providing the necessary clearance space for mechanical movement, thereby improving the operational flexibility and reliability of the air handling unit.

[0049] According to some embodiments of this application, the deflector assembly 14 includes: a deflector body 141 and a movable plate 142. The deflector body 141 is fixedly connected to the air duct assembly 12. The movable plate 142 is movably disposed on the deflector body 141 to switch between a first state and a second state. The movable plate 142 can be translated relative to the deflector body 141 or rotatably connected to the deflector body 141.

[0050] In this embodiment, the guide vane body 141 is fixedly connected to the air duct assembly 12, providing a foundation and structural support for the installation of the entire guide vane assembly 14, ensuring a stable connection between the guide vane assembly 14 and the air duct assembly 12. A movable plate 142 is movably mounted on the guide vane body 141. The movable plate 142 can translate relative to the guide vane body 141 to move closer to or further away from the host unit 11. The movable plate 142 can also be rotatably connected to the guide vane body 141, thereby adjusting the angle of the movable plate 142 relative to the air duct assembly 12, thus adjusting the gap between the movable plate 142 and the host unit 11, and also allowing it to avoid the host unit 11 during the rotation of the air duct assembly 12. In other embodiments, the movable plate 142 can both translate with and rotate relative to the guide vane body 141.

[0051] According to some embodiments of this application, a flexible seal 19 is formed on the edge of the movable plate 142 facing the host 11. When the movable plate 142 is in the extended first state, the edge of the movable plate 142 can contact the surface of the host 11, and the flexible seal 19 can undergo elastic deformation to make the elastic seal 19 fit tightly against the surface of the host 11, thereby effectively sealing the gap between the air duct assembly 12 and the host 11, significantly reducing air leakage, improving airflow efficiency, and can be used to block dust and noise.

[0052] The flexible seal 19 is connected to the movable plate 142, ensuring a good seal during state switching only in the first state, without mechanical jamming or wear. When the movable plate 142 moves to the first state, the flexible seal 19 is passively compressed and completes the seal, ensuring airtightness; when it is necessary to switch to the second state to avoid rotation, the elasticity of the flexible material allows the seal to smoothly disengage, ensuring that the movable plate 142 can smoothly retract to form a clearance space.

[0053] According to some embodiments of this application, a receiving space 1410 is formed inside the deflector body 141, and at least a portion of the movable plate 142 is disposed within the receiving space 1410. The deflector body 141 forms the receiving space 1410 by providing a cavity structure inside itself; in some embodiments, a receiving groove may also be formed on the surface of the deflector. The receiving space 1410 provides space for the installation and movement of the movable plate 142. In the second state, the movable plate is received within the receiving space 1410, making the overall structure of the deflector assembly 14 more compact. At least a portion of the movable plate 142 is disposed within this receiving space 1410, and the movement of the movable plate 142 relative to the deflector body 141 has a defined trajectory and limits, ensuring the stability and accuracy of the movement of the movable plate 142 during translation or rotation, preventing offset or jamming, thereby ensuring the reliability of state switching.

[0054] The main body 141 of the deflector plate has a front side plate 1411 and a rear side plate 1412 spaced apart in the thickness direction, forming a receiving space 1410 between the front side plate 1411 and the rear side plate 1412. The receiving space 1410 within the main body 141 of the deflector plate and the movable design of the movable plate 142 constitute an integrated motion module. The receiving space 1410 not only provides space for storing the movable plate 142, but also expands the range of motion of the movable plate 142, allowing the movable plate 142 to extend and retract when switching between the first and second states.

[0055] According to some embodiments of this application, a drive component 145 is provided in the receiving space 1410, and a guide component 144 is provided on the movable plate 142 to cooperate with the drive component 145. Under the drive of the drive component 145, the movable plate 142 can selectively translate relative to the guide plate body 141 in a direction closer to or farther away from the host 11.

[0056] The driving component 145 is disposed within the receiving space 1410. The driving component can actively and controllably drive the movable plate 142 to move, thereby switching between the first state and the second state. The movable plate 142 is provided with a guide component 144 that cooperates with the driving component 145. Through the interaction between the guide component 144 and the driving component 145, such as direct transmission or magnetic engagement, the power output by the driving component 145 is converted into linear or rotational motion of the movable plate 142.

[0057] Driven by the drive component 145, the movable plate 142 can selectively translate relative to the guide plate body 141 in a direction closer to or farther from the host 11, so that the movable plate 142 has bidirectional linear motion capability, and can accurately position the movable plate 142 to the first state for sealing or the second state for avoidance, thereby realizing the active switching between the two functional states.

[0058] In this application, the drive component 145 serves as a power source to provide power for the movement of the movable plate 142, and the guide component 144 serves as a motion constraint for the movable plate 142 to limit the movement trajectory and motion state of the movable plate 142, ensuring that the movable plate 142 can move stably in two directions, close to the host 11 and retracted away from the host 11, according to a preset path.

[0059] According to some embodiments of this application, the drive component 145 is configured as a gear rotatably disposed within the receiving space 1410, and the guide component 144 is configured as a rack extending in the translational direction of the movable plate 142. The rack and gear cooperate to drive the movable plate 142 to translate. Utilizing the rotational motion of the gear as the power input, the gear rotation is stable, continuous, and the torque output is easily controlled, providing a power source for the linear motion of the movable plate 142. Furthermore, the rotation of the gear can be achieved through manual drive by the user.

[0060] The guide component 144 is configured as a rack extending in the translational direction of the movable plate 142. The rack moves in a straight line, providing a linear path guide for the movement of the movable plate 142. The rack meshes with the gear to drive the movable plate 142 to translate, converting the rotational motion of the drive gear into the linear motion of the movable plate 142, thus realizing power transmission to drive the movable plate 142 to switch between the first state and the second state.

[0061] In some embodiments of this application, the drive component 145 includes a knob 18, which is connected to the drive component 145 to drive the drive component 145 to rotate.

[0062] According to some embodiments of this application, the receiving space 1410 is provided with an outlet suitable for the movable plate 142 to extend out, and the front and / or rear edges of the outlet are formed with a bottom sealing plate 1413 that extends in the front-rear direction and abuts against the movable plate 142.

[0063] The extended outlet of the movable plate 142 allows it to smoothly extend out of the receiving space 1410 to reach a first state, or retract back into the receiving space 1410 to maintain a second state. A bottom sealing plate 1413 is formed on the front and / or rear edge of the outlet, extending in the front-rear direction and abutting against the movable plate 142. The bottom sealing plate 1413 can contact the surface of the movable plate 142 when it extends out of the receiving space 1410, serving to support the movable plate 142 and close the outlet. Supported by the bottom sealing plate 1413, the movable plate 142 can maintain its extended posture more stably, ensuring the reliability of the sealing effect of the guide plate assembly 14 in the first state.

[0064] According to some embodiments of this application, a guide groove 143 extending in the translation direction is formed on the movable plate 142, and a guide protrusion 1414 is formed on the guide plate body 141. The guide protrusion 1414 is received in the guide groove 143 and limits the movement trajectory of the movable plate 142 during the translation process.

[0065] The guide groove 143 on the movable plate 142 and the guide plate body 141 form a guide protrusion 1414 that cooperate with each other to guide and constrain the movement of the movable plate 142. The guide protrusion 1414 is housed in the guide groove 143 and limits the movement trajectory of the movable plate 142 during its translation. Through the embedded cooperation of the protrusion and the groove, the movement of the movable plate 142 is constrained to a single linear translational degree of freedom, effectively preventing the movable plate 142 from deflecting, warping or deviating from the predetermined path during its movement, and ensuring the smoothness and accuracy of the movement process.

[0066] According to some embodiments of this application, the deflector body 141 and the movable plate 142 are respectively provided with a first limiting component and a second limiting component. One of the first limiting component and the second limiting component is a limiting protrusion 16, and the other of the first limiting component and the second limiting component is a plurality of limiting grooves 17 arranged sequentially in the translational direction of the movable plate 142. The limiting protrusion 16 can selectively cooperate with any one of the limiting grooves 17 to restrict the movement of the movable plate 142 relative to the deflector body 141.

[0067] One of the first and second limiting components is a limiting protrusion 16, which can serve as a protruding positioning point and can be embedded in a corresponding groove to achieve mechanical interlocking. The other component of the first and second limiting components is a plurality of limiting grooves 17 arranged sequentially in the translational direction of the movable plate 142. The arrangement of the plurality of limiting grooves 17 provides a plurality of fixed positioning points, providing the movable plate 142 with a plurality of preset positions that can be fixed.

[0068] The limiting protrusion 16 can selectively engage with any limiting groove 17 to restrict the movement of the movable plate 142 relative to the guide plate body 141. By engaging the limiting protrusion 16 with different grooves, multiple points of selective locking during the translational stroke of the movable plate 142 can be achieved, reliably fixing the movable plate 142 in different extended or retracted positions, thereby giving the movable plate 142 multiple stable working states.

[0069] A boss 161 is provided on the movable plate 142. A recess for accommodating the elastic member 162 is formed on the boss 161. A limiting protrusion 163 is received in the recess and abuts against the elastic member 162. The limiting protrusion 163 is kept protruding towards the groove for matching with different grooves.

[0070] The air handling unit provided in this application, through the coordinated operation of the main unit 11, the rotatable air duct assembly 12, and the deflector assembly 14 with state switching function, effectively balances the needs for omnidirectional air intake and motion interference prevention. The deflector assembly 14, through the movable connection between the movable plate 142 and the deflector body 141, and its internal gear rack, achieves switching between extended sealing and retracted avoidance states. While ensuring airtightness and airflow range, it significantly improves the operational flexibility, operational reliability, and overall structural durability of the unit.

[0071] According to some embodiments of this application, the host 11 includes: a host housing 111, an airflow processing chamber 110 is formed inside the host housing 111, and an exhaust hole 1110 communicating with the airflow processing chamber 110 is provided at the rear of the host housing 111; a fan module is disposed inside the host housing 111, 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.

[0072] 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.

[0073] According to some embodiments of this application, an airflow processing chamber 110 is provided with a wind turbine 113. The wind turbine 113 includes: a wheel disk 1131, which is disposed at the bottom of the wind turbine chamber and is used to connect with a drive member 114; multiple blades 1132, which are arranged 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.

[0074] 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.

[0075] In some embodiments of this application, an illumination element 126 is provided on the air duct assembly 12. The illumination element 126 is integrated and installed on the annular outer wall of the air duct assembly 12. It can use an LED light source and be equipped with a light-diffusing plate to achieve a uniform lighting effect. In the embodiments of this application, the illumination element 126 provides functional lighting without affecting airflow.

[0076] In some embodiments of this application, the air intake of the air duct assembly 12 is configured as a slit with an inner edge of the air duct assembly, so as to configure the air intake as an air inlet gap 122. The slit-type air inlet increases the air intake pressure by reducing the air inlet area, thereby enhancing the air intake effect of the air duct assembly and improving the purification capacity of the air handling device according to this application.
