Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, and in particular to an air treatment device. Background Technology

[0002] In applications such as pet air purifiers and other air handling equipment, these devices are often designed for pets to interact with in open spaces to enhance interaction. However, in actual use, the movement or leaning of pets (especially large pets) can easily cause the entire unit to tip over, affecting its normal operation and potentially posing a safety hazard.

[0003] Existing technologies typically increase the contact area between the chassis and the ground to enhance the anti-tipping lever, or increase the overall weight of the device by adding counterweights to improve stability and reduce the risk of tipping. While these methods can improve the anti-tipping performance of the device to some extent, they still cannot completely prevent the device from being pushed over by strong pets. Once the device tipps over, existing structures cannot automatically reset it, requiring manual intervention to right it, which is not only inconvenient to use but also interrupts the purification function, affecting the user experience. Therefore, there is an urgent need for an air handling unit that can automatically return to an upright position after tipping over. Utility Model Content

[0004] The main purpose of this invention is to provide an air handling device that addresses the problem that existing air handling devices are prone to tipping over when touched or leaned on by pets, and that manual righting is required after tipping over.

[0005] To achieve the above objectives, the air handling equipment proposed in this utility model includes:

[0006] The main body includes an outer bottom shell, the bottom of which is configured as a downwardly convex curved surface, and a balancing cavity is formed inside the outer bottom shell, the balancing cavity being located near the bottom of the main body;

[0007] At least one counterweight is rotatably disposed within the balancing cavity, the center of gravity of the counterweight being located below the center of gravity of the air handling equipment, to provide a restoring torque to automatically return the air handling equipment to its upright position after it tilts; and...

[0008] The support section is elastically extendable in the vertical direction, and the support section and the lowest point of the bottom of the outer shell are used to jointly support the air handling equipment.

[0012] In one embodiment, the support portion includes a plurality of retractable support members, which are spaced apart circumferentially along the main body and located around the lowest point of the bottom of the outer shell.

[0013] In one embodiment, the outer bottom shell is provided with an installation port communicating with its inner cavity, and the support part passes through the installation port and is movably disposed relative to the installation port;

[0014] The subject also includes:

[0015] A mounting plate is disposed within the outer bottom shell, the bottom of the mounting plate being fixedly connected to the top of the support portion, and the balancing cavity is disposed on the top of the mounting plate; and,

[0016] An elastic element is disposed between the mounting plate and the outer bottom shell.

[0017] In one embodiment, the mounting plate is adapted to the inner wall surface of the outer bottom shell, and an annular gap is defined between the mounting plate and the inner wall surface of the outer bottom shell, wherein the annular width of the annular gap is set to be smaller than the size of the counterweight.

[0018] In one embodiment, the outer periphery of the mounting plate is inclined upward from the inside out.

[0019] In one embodiment, a connection structure is provided between the balancing cavity and the mounting plate, the connection structure including at least one of a screw connection structure, an adhesive connection structure, a welding structure, a snap-fit ​​structure, and a magnetic attraction structure.

[0021] The mounting plate is provided with a first connecting hole through the positioning protrusion, and the balancing cavity is provided with a second connecting hole through the positioning protrusion.

[0022] In one embodiment, the main body further includes an inner bottom shell and a cover installed in the inner cavity of the outer bottom shell.

Combined with the elastically extendable support, the unit can automatically return to an upright position using gravity and structural coordination after being bumped or pushed over by a pet, without human intervention. This maintains the normal operation of the equipment and reduces work interruptions and potential safety issues caused by tipping over. Attached Figure Description

[0038] This utility model relates to an air handling device, which is particularly suitable for use in environments where pets coexist. It solves the technical problem that existing devices are easily tipped over by large pets during pet interaction, and cannot automatically return to an upright position after tipping over, requiring manual correction.

[0039] This equipment can be used in various places requiring air purification, such as homes, offices, hospitals, laboratories, and vehicles. It effectively removes particulate pollutants from the air, such as dust, pet hair, pollen, and PM2.5, improving air quality. The equipment can be equipped with filtration units, such as pre-filters, HEPA filters, and activated carbon filters, to achieve multi-stage air purification. Furthermore, this air handling unit can be configured as a vertical, tabletop, or portable purification device, suitable for indoor air circulation and purification in both fixed and mobile environments.

[0040] For ease of understanding and explanation, the following embodiments use a vertical air purifier as an example, and describe the filtration method and automatic return-to-center function in detail with respect to its structural features. It should be understood that the technical solution of this utility model is not limited to vertical models, but can also be applied to other forms of air handling equipment. The specific form can be adjusted according to actual usage needs, and this specification does not limit it.

[0041] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the air handling device 100 includes a main body 1, at least one counterweight 2, and a support 3. The main body 1 includes an outer bottom shell 11, the bottom of which is configured as a downwardly convex curved surface. A balancing cavity 1a is formed inside the outer bottom shell 11, and the balancing cavity 1a is located near the bottom of the main body 1. The counterweight 2 is rotatably disposed within the balancing cavity 1a, and the center of gravity of the counterweight 2 is located below the center of gravity of the air handling device 100, so as to provide a restoring torque to automatically return the air handling device 100 to its upright position after it tilts. The support 3 is elastically extendable and retractable in the vertical direction, and the lowest point of the support 3 and the bottom of the outer bottom shell 11 are used to jointly support the air handling device 100.

[0042] It should be noted that the bottom of the outer shell 11 of the main body 1 is designed with a downwardly convex curved surface structure. This curved surface can be specifically implemented as a sphere, ellipsoid, or a spherical crown shape. Of course, other continuous and smooth arc contours can also be used, such as a parabola with a circular arc transition. The specific shape can be adaptively designed according to the overall height, weight, and center of gravity position of the machine, and this specification does not limit it. This curved surface structure allows the main body 1 to form a point contact or a small area contact with the ground, forming a swinging base similar to a roly-poly toy, providing a fulcrum for the rotation of the entire machine. When the equipment tilts, the main body 1 can swing around the contact point between the curved surface and the ground.

[0043] A balancing cavity 1a is provided inside the outer bottom shell 11. The balancing cavity 1a is located in the area near the bottom of the main body 1, and its space is set sufficiently so that the counterweight 2 can roll freely. The balancing cavity 1a can be set as a closed cavity or a semi-closed form, and can be integrally formed into the outer bottom shell 11 by plastic or metal material. It can also be set independently and fixed to the inner wall of the bottom shell. The specific installation method is not limited.

[0044] The counterweight 2 is a movable weight with a certain mass, such as a solid metal ball (e.g., a steel ball, a cast iron ball), a metal block, or a rolling body made of other high-density materials. The counterweight 2 is placed inside the balancing cavity 1a and can roll downwards along the inner wall of the cavity under the influence of gravity. By controlling the mass of the counterweight 2 and its range of motion within the cavity, its overall center of gravity is positioned below the overall center of gravity of the machine, thereby generating an eccentric moment when the equipment tilts, causing the main body 1 to automatically return to its upright position after tilting.

[0045] The support part 3 is elastically telescopic in the vertical direction, for example, by using a helical spring, rubber elastic column, bellows, or a telescopic rod structure with an internal spring. One end of the support part 3 is connected to the lowest point of the bottom of the main body 1, and the other end is used to contact the ground and bear part of the load. In the normal upright state of the air handling equipment 100, the support part 3 is in a compressed state, providing stable support; when the air handling equipment 100 is tilted, the support part 3 undergoes a certain degree of deformation and displacement, avoiding obstruction of the main body 1's return-to-right movement, and also playing a buffering role. The number of support parts 3 can be one or more, and their arrangement can be set at the center of the curved surface or in the surrounding area according to structural needs; the specific number and layout are not limited.

[0046] By setting the bottom of the main body 1 as a downward convex curved surface and setting a balance cavity 1a at the lower part of the interior to accommodate the rollable counterweight 2, combined with the joint action of the elastic support 3, the air handling equipment 100 can automatically return to an upright state by utilizing the restoring torque generated by the rolling of the counterweight 2 and the swaying characteristics of the curved bottom shell after being pushed by a pet and tilted or completely tipped over, without human intervention, thus enabling continuous operation and improving the safety and convenience of equipment use.

[0047] Specifically, in order to make the device have more stable swaying characteristics during tilting and to ensure that the counterweight 2 rolls smoothly within the cavity, please refer to... Figure 1 and Figure 2 In some embodiments, the bottom of the outer shell 11 is configured as a sphere, ellipsoid, elongated sphere, or a quasi-spherical structure composed of polygonal surfaces; and / or, the counterweight 2 is configured as a tetrahedron, cube, cuboid, sphere, ellipsoid, truncated polyhedron, or a quasi-spherical structure composed of multiple curved surfaces and / or planes; and / or, the inner wall surface of the balancing cavity 1a is configured as a sphere, ellipsoid, elongated sphere, or a quasi-spherical structure composed of polygonal surfaces.

[0048] Specifically, the bottom of the outer shell 11 is set as a downward convex curved surface, which can be implemented as a sphere, ellipsoid, or elongated sphere. Therefore, such curved surface structure can provide a continuous and smooth contact transition, so that the main body 1 can swing smoothly around the ground contact point during the tilting process.

[0049] In addition, the bottom curved surface can also be composed of multiple planes spliced ​​together to form a spherical structure, such as a polyhedral outline formed by a regular polygon or triangular facet array, as long as its overall shape is convex and can achieve a swinging motion. The specific form of the curved surface can be selected according to the position of the overall center of gravity, the size of the bottom shell, and the materials and processes used; this manual does not impose any restrictions on this.

[0050] The counterweight 2 is configured as a solid structure that can roll freely within the balancing cavity 1a. It can be specifically implemented as a sphere or an ellipsoid. Such a shape has no sharp edges and low rolling resistance, and can move smoothly within the cavity so as to generate an eccentric torque in time when the equipment is tilted.

[0051] The counterweight 2 can also be configured as a tetrahedron, cube, cuboid, or truncated polyhedron. Such structures can control the rolling characteristics by adjusting the mass distribution.

[0052] Furthermore, the counterweight 2 can also adopt a quasi-spherical structure composed of multiple curved surfaces and / or planes, such as a truncated icosahedron similar to the surface of a soccer ball or other near-spherical bodies, as long as it can roll effectively within the cavity. The specific form of the counterweight 2 can be determined according to the required weight and spatial layout, and this specification does not limit its specific configuration.

[0053] The inner wall surface of the balancing cavity 1a is set as a curved surface that matches the shape of the counterweight 2, such as a sphere, an ellipsoid, or a long sphere, so that the counterweight 2 has sufficient room to move within the cavity and avoids jamming.

[0054] Of course, the inner wall surface can also be constructed from polygonal surfaces to form a spherical structure to match the specific shape of the counterweight 2. A smooth coating or padding can be applied to the inner wall of the cavity to reduce rolling friction. The shape of the cavity and the shape of the counterweight 2 can be designed in combination, as long as it allows the counterweight 2 to roll freely under gravity. The specific fit can be adjusted according to actual needs, and this specification does not impose any limitations on this.

[0055] By setting the bottom of the outer shell 11 and the inner wall of the balance cavity 1a as a spherical, ellipsoidal, elongated spherical or near-spherical structure, and setting the counterweight 2 as a sphere, ellipsoid, polyhedron or near-spherical structure, the main body 1 can have a stable swing trajectory when tilted, and the counterweight 2 can roll smoothly in the cavity to generate an effective restoring torque.

[0056] Specifically, please refer to Figure 2 In this embodiment, the support part 3 includes a plurality of retractable support members 31, which are arranged at intervals along the circumference of the main body 1 and are located around the lowest point of the bottom of the outer shell 11.

[0057] It should be noted that the support member 31 can take the form of a spring structure, an elastic rubber column, or a telescopic rod with built-in buffer material, which can undergo elastic deformation in the vertical direction. When the air handling unit 100 is in an upright state, each support member 31 is in a compressed state, and together with the lowest point of the bottom of the outer shell 11, it contacts the ground, playing a role in stabilizing the load.

[0058] The number of support components 31 can be three, four, or more, and the specific number can be set according to the bottom space of the main body 1 and the weight distribution of the whole machine. The spacing angle between the support components 31 can be uniform or non-uniform, as long as it can ensure that the equipment remains stable when static.

[0059] Understandably, the installation position of the support member 31 avoids the central area of ​​the bottom of the outer shell 11. That is, a certain range is reserved around the lowest point without the support member 31. By setting multiple support members 31, when the equipment tilts, the bottom curved surface can gradually contact the ground and form a fulcrum, so that it can swing around the point. With the rolling of the counterweight 2, it can automatically return to the correct position. Moreover, multiple support members 31 can form a support ring together to distribute the weight of the whole machine and provide uniform support force.

[0060] It should also be noted that the support member 31 can be directly fixed to the inner wall of the outer bottom shell 11 or the internal bracket, or it can be connected to the bottom of the main body 1 through an independent mounting base. Its extension stroke is set according to the tilt angle requirements of the equipment, so that the support member 31 absorbs the impact during small-amplitude shaking, and ensures that the curved surface of the bottom of the main body 1 fully contacts the ground during large-angle tilting. This manual does not limit the specific type and installation method of the support member 31; an adaptation scheme can be selected according to the actual structural needs, and no limitations are imposed in this regard.

[0061] Specifically, please refer to Figure 2 In one embodiment, the outer bottom shell 11 is provided with a mounting port 11a communicating with its inner cavity. The support part 3 passes through the mounting port 11a and is movably disposed relative to the mounting port 11a. The main body 1 also includes a mounting plate 14 and an elastic member 15. The mounting plate 14 is disposed inside the outer bottom shell 11, and the bottom of the mounting plate 14 is fixedly connected to the top of the support part 3. The balancing cavity 1a is disposed at the top of the mounting plate 14. The elastic member 15 is disposed between the mounting plate 14 and the outer bottom shell 11.

[0062] Understandably, the mounting opening 11a on the outer bottom shell 11 is located in its bottom area, for the support part 3 to pass through and extend partially to the outside to contact the ground. The support part 3 passes through the mounting opening 11a and is movably disposed relative to the mounting opening 11a, allowing it to extend and retract in the vertical direction. The mounting opening 11a can guide or limit the support part 3 to a certain extent, and can also allow the support part 3 to float within a certain range; the specific form of engagement is not limited.

[0063] This manual does not limit the specific location, number, or shape of the mounting port 11a, nor does it limit the type, number, or arrangement of the elastic elements 15. It can be adapted to the structural form of the support part 3 and the weight of the whole machine. The specific implementation plan can be determined according to actual needs, and no limitation is made in this regard.

[0064] An installation plate 14 is provided inside the main body 1. The installation plate 14 is fixed in the inner cavity of the outer bottom shell 11, and its bottom is fixedly connected to the top of the support part 3, thereby transmitting the movement of the support part 3 to the structure of the main body 1. The balancing cavity 1a is located in the top area of ​​the installation plate 14, that is, above the support part 3, and is supported by the installation plate 14, so that the balancing cavity 1a where the counterweight part 2 is located moves up and down with the installation plate 14. During the compression or rebound process, the support part 3 drives the installation plate 14 to move, thereby affecting the dynamic change of the center of gravity of the whole machine.

[0065] The elastic element 15 is disposed between the mounting plate 14 and the outer bottom shell 11, and can be specifically implemented as a coil spring or a rubber pad, etc., to generate elastic deformation and store energy when the support part 3 is compressed, and push the mounting plate 14 to return to its original position after the external force is released. When the air handling equipment 100 is subjected to an external force that causes the support part 3 to be compressed, the elastic element 15 is compressed; when the external force is removed, the elastic element 15 restores its deformation, driving the support part 3 and the mounting plate 14 back to their initial positions, thereby assisting the air handling equipment 100 to restore its upright posture.

[0066] By providing an installation port 11a in the outer bottom shell 11 and inserting the support part 3 through it and fixing it to the mounting plate 14, combined with the elastic element 15 provided between the mounting plate 14 and the outer bottom shell 11, the support part 3 has the ability to extend and guide and automatically reset, so that it can flexibly make way when the air handling equipment 100 is tilted by force, and provide auxiliary restoring force during the return process, thereby improving the response of the support structure.

[0067] Furthermore, to prevent the counterweight 2 from dislodging from the gap between the mounting plate 14 and the inner wall of the outer bottom shell 11 during rolling due to moving to the edge area of ​​the mounting plate 14, please refer to... Figure 2 In this embodiment, the mounting plate 14 is adapted to the inner wall surface of the outer bottom shell 11, and an annular gap 1b is defined between the mounting plate 14 and the inner wall surface of the outer bottom shell 11. The annular width of the annular gap 1b is set to be smaller than the size of the counterweight 2.

[0068] It should be noted that the annular width of the annular gap 1b, i.e., the minimum radial distance between the edge of the mounting plate 14 and the inner wall of the outer bottom shell 11, is set to be smaller than the size of the counterweight 2. The size of the counterweight 2 here refers to its maximum outer diameter or longest side length, which is determined according to the actual shape of the counterweight 2.

[0069] This manual does not limit the specific fixing method of the mounting plate 14. Any feasible method such as snap-fit, screw connection, heat fusion, or bonding can be used to achieve its positioning in the inner cavity. The specific value of the annular gap 1b can be adjusted according to the type of counterweight 2 and the overall structure of the machine, as long as it is smaller than the size of the counterweight 2. The specific value is not limited.

[0070] By controlling the ring width to be smaller than the size of the counterweight 2, the counterweight 2 cannot fall through the gap into the area where the support 3 is located or other internal spaces, thus serving as a limiting and blocking function. Especially when the balancing cavity 1a adopts a semi-enclosed structure, formed by the inner bottom shell 12 and the cover 13, the mounting plate 14, as the base supporting the balancing cavity 1a, may have an annular gap 1b between its edge and the outer bottom shell 11, which could become a path for the counterweight 2 to accidentally move out. Through the above-mentioned dimensional matching relationship, the counterweight 2 can be prevented from rolling into non-designed areas during violent shaking or tilting of the air handling equipment 100, ensuring that the counterweight 2 always moves within the predetermined cavity.

[0071] Furthermore, in order to guide the counterweight 2 to gather in the central region of the balance cavity 1a during the rolling process and reduce its tendency to move towards the edge region, in this embodiment, the outer periphery of the mounting plate 14 is inclined upward from the inside out.

[0072] Understandably, the mounting plate 14 has a disc-shaped or umbrella-shaped structure, with its inner side lower and its outer side higher. The inclined structure can form a centripetal guide surface. When the counterweight 2 rolls into the cavity and approaches the edge area, it will be guided back to the center area of ​​the mounting plate 14 due to the reaction force of gravity. This ensures that the counterweight 2 is stably centered after the equipment returns to its normal position, preventing it from lingering at the edge for a long time and affecting the response speed during the next tilt.

[0073] This manual does not limit the specific outline of the inclined section of the mounting plate 14. It can be a conical surface, a parabolic surface, or a polygonal inclined surface, or it can be achieved by combining various curved surface transitions, as long as the overall inclined trend is lower on the inside and higher on the outside. The specific structure can be adjusted according to the internal space layout and center of gravity design requirements of the outer bottom shell 11, and there are no restrictions on this.

[0074] Thus, by setting the outer periphery of the mounting plate 14 as a disc-shaped structure that tilts upward from the inside out, a centripetal guide surface is formed, so that the counterweight 2 is naturally guided to the central area during the rolling process, thereby avoiding it from being located off the edge for a long time and ensuring that the counterweight 2 can generate a restoring torque in time when the air handling equipment 100 tilts.

[0075] Specifically, in this embodiment, a connection structure is provided between the balancing cavity 1a and the mounting plate 14. The connection structure includes at least one of the following: screw connection, adhesive connection, welding connection, snap-fit ​​connection, and magnetic attraction connection.

[0076] For example, the balancing chamber 1a can be locked onto the mounting plate 14 with screws, or quick assembly can be achieved by snap-fit; if it is made of plastic, ultrasonic welding or hot-melt connection can be used; if it is made of metal, adhesive can be used for bonding; in addition, detachable connection can also be achieved by magnetic adsorption.

[0077] The specific form of the above-mentioned connection structure is not limited, and an appropriate solution can be selected according to the material type, assembly process, and structural strength requirements. Multiple connection methods can also be combined to improve connection reliability.

[0078] By providing at least one connection method, including screwing, bonding, welding, snap-fit ​​or magnetic structure, between the balance cavity 1a and the mounting plate 14, the balance cavity 1a can be stably installed on the mounting plate 14, thereby ensuring that the counterweight 2 is always in the preset cavity during the operation or tilting of the air handling equipment 100.

[0079] For further information, please refer to [link / reference]. Figure 2 In this embodiment, a positioning protrusion 16 extends upward from the bottom wall of the outer bottom shell 11. A first connecting hole is provided on the mounting plate 14, which passes through the positioning protrusion 16, and a second connecting hole is provided on the balancing cavity 1a, which also passes through the positioning protrusion 16. During assembly, the positioning protrusion 16 passes through the first and second connecting holes sequentially, ensuring that the mounting plate 14 and the balancing cavity 1a remain accurately aligned with the outer bottom shell 11 during installation, preventing misalignment.

[0080] It should be noted that the positioning protrusion 16 can be molded from plastic or metal and can be integrally injection molded with the outer bottom shell 11 or installed separately. When metal or hard plastic is used, its structure has sufficient rigidity, and if the counterweight 2 collides with the positioning protrusion 16 during rolling, it can produce a clear sound. This sound can attract the attention of pets, enhancing the fun of the air treatment device 100 as an interactive toy, so that the device can attract pets to play while performing its air purification function.

[0081] The number of positioning protrusions 16 can be one or more, distributed circumferentially to improve positioning stability. The positions of the first connecting hole and the second connecting hole correspond to the positioning protrusions 16, and the hole shape can be circular, oblong, or irregularly shaped with limiting grooves, with no specific limitation on the form.

[0082] This manual does not limit the specific height, diameter, or cross-sectional shape of the positioning protrusion 16, nor does it limit the choice of its material. It can be adjusted according to structural strength, assembly requirements, and acoustic effects.

[0083] By setting an upwardly extending positioning protrusion 16 on the bottom wall of the outer shell 11 and corresponding through holes on the mounting plate 14 and the balance cavity 1a, the assembly and positioning between components can be achieved; at the same time, the counterweight 2 makes a sound by colliding with the positioning protrusion 16 during the rolling process to attract the pet's attention and enhance the interaction between the air treatment device 100 and the pet, making it have both purification function and toy attributes.

[0084] Specifically, to ensure that the counterweight 2 is stably housed inside the balance chamber 1a during the use of the air handling unit 100, please refer to... Figure 3 In another embodiment, the main body 1 further includes an inner bottom shell 12 and a cover 13 installed in the inner cavity of the outer bottom shell 11. One end of the inner bottom shell 12 is provided with an opening, and the cover 13 covers the opening to form a balanced cavity 1a with the inner bottom shell 12.

[0085] Specifically, an opening is provided at one end of the inner bottom shell 12, and the cover 13 is fixed to the opening so that the inner bottom shell 12 and the cover 13 together form a closed balance cavity 1a. Thus, the balance cavity 1a is in a semi-closed state during the assembly stage, and the counterweight 2 can be directly inserted into the inner bottom shell 12 from the opening side. After placement, the cover 13 is then installed in place.

[0086] This manual does not limit the specific connection method between the inner bottom shell 12 and the cover 13. It can be an interference fit, ultrasonic welding, threaded connection, or snap-fit ​​structure, as long as it can achieve the closure of the balanced cavity 1a. At the same time, the installation position of the inner bottom shell 12 can be flexibly arranged in the bottom area of ​​the inner cavity of the outer bottom shell 11 to adapt to different center of gravity design requirements. The specific arrangement method can be determined according to the actual structural needs, and this manual does not limit it.

[0087] It should also be noted that the shape of the cover 13 is adapted to the outline of the opening, and can be circular, square or polygonal. The specific size and connection method can be adjusted according to the internal space layout of the outer bottom shell 11.

[0088] By providing an inner bottom shell 12 with an opening and a detachable cover 13, the counterweight 2 can be directly inserted into the balancing chamber 1a during assembly, thus simplifying the manufacturing process. After the entire machine is assembled, the balancing chamber 1a formed by the inner bottom shell 12 and the cover 13 is a fully enclosed structure, ensuring that the counterweight 2 is always restricted to rolling freely within the chamber during equipment operation and will not detach due to violent shaking. This balances ease of assembly with reliable operation of the air handling equipment 100.

[0089] Specifically, in this embodiment, the counterweight 2 is made of at least one of the following materials: metal, plastic, concrete, wood, stone, or polymer composite material. For example, using a metal material can increase density to enhance the counterweight effect, using plastic or composite materials can facilitate the molding of complex shapes, and concrete, stone, or wood can provide specific quality characteristics. The specific material selection can be determined according to the required weight, cost, and processing method, and is not limited to the above list.

[0090] The outer shell 11 is made of at least one of the following materials: ABS, PC, PP, PTFE, thermoplastic plastic, metal, or alloy. Since the shell serves as an external structural component of the air handling equipment 100, it needs to possess a certain degree of rigidity and wear resistance. Engineering plastics are chosen for their ease of injection molding, while metals or alloys are suitable for high-strength applications. The specific material can be selected based on the appearance design, structural strength, and operating environment.

[0091] The balancing cavity 1a is made of at least one of the following materials: ABS, PC, PP, PTFE, thermoplastic plastic, metal, or alloy. The material selection must consider the frictional characteristics with the counterweight 2 and the durability of long-term rolling. It can be made of the same or different material as the outer bottom shell 11, depending on the assembly method and structural layout.

[0092] This manual does not limit the specific material types of the above components, nor does it restrict their combination methods, as long as the corresponding functions can be achieved. The materials of each component can be flexibly selected according to actual production needs, cost control, and performance requirements, and there are no restrictions on this.

[0093] By manufacturing the counterweight 2, the outer bottom shell 11, and the balance chamber 1a using a variety of optional materials, the air handling equipment 100 can flexibly balance weight, strength, cost, and manufacturability according to the actual application scenario while ensuring the automatic return function.

[0094] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
