Description

Technical Field

[0001] This utility model belongs to the technical field of air purification equipment, and specifically relates to an air purifier assembly structure. Background Technology

[0002] As a key device for improving indoor air quality, air purifiers rely on the filtering effect of filters or screens on harmful substances such as particulate matter and gaseous pollutants in the air. In actual use, as the life cycle of the filter ends, users need to regularly disassemble and replace the filter to maintain purification efficiency. Existing air purifiers generally adopt a single-unit box structure, which integrates fan components, filtration system and airflow channels.

[0003] Currently, in application scenarios that require multiple units to work together, due to the lack of an effective combination and connection mechanism between the equipment, they are usually placed side by side in the horizontal direction, which results in a multiple increase in the area occupied by the equipment. When stacking them vertically, they can only rely on a simple layering method to achieve vertical stacking, but due to the lack of a positioning structure between the shells, there is a risk of sliding and tipping, and the overall center of gravity shifts after stacking, which can easily cause safety hazards. Summary of the Invention

[0004] This invention addresses the aforementioned problems in the existing technology by proposing a combined structure for air purifiers that can be stably stacked vertically.

[0005] This utility model can be achieved through the following technical solutions:

[0006] An air purifier assembly structure includes:

[0007] The first air purifier includes a first air inlet duct and a first air outlet duct that are axially joined together. The end face of the first air outlet duct away from the first air inlet duct forms a first mounting surface. The outer edge of the first mounting surface is provided with a first connecting structure, and the middle part of the first mounting surface is recessed to form a receiving groove.

[0008] The second air purifier includes a second air inlet duct and a second air outlet duct that are axially connected. The two end faces of the second air inlet duct and the second air outlet duct that are opposite to each other form a second assembly surface. The outer edge of the second assembly surface is provided with a second connection structure that is adapted to the first connection structure.

[0009] The first air outlet and the second air outlet are respectively provided with a first roller 122 and a second roller 221;

[0010] When the first air purifier and the second air purifier are stacked in the same direction, the first air inlet duct is connected to the second air outlet duct. At this time, the first connecting structure and the second connecting structure form a circumferential constraint fit, and the second roller 221 is stored in the receiving groove.

[0011] When the first air purifier and the second air purifier are stacked in reverse, the first air inlet duct is connected to the second air inlet duct, and at this time the first connecting structure and the second connecting structure form a circumferential constraint fit.

[0012] As a further improvement of this utility model, the first connecting structure is a circumferentially extending annular groove, and the second connecting structure is an annular protrusion that is interference-fitted with the annular groove.

[0013] As a further improvement of this utility model, the second assembly surface is also provided with concentrically arranged annular ribs, the annular ribs being spaced apart from the annular protrusions. When the annular protrusions are embedded in the annular groove, the annular ribs are located in the receiving groove and abut against the inner edge of the annular groove.

[0014] As a further improvement of this utility model, the first air inlet and the second air inlet both include an air inlet body with the same air inlet structure, and each side of the air inlet body is an air inlet surface and has an air inlet.

[0015] Both the first and second air outlet ducts include an air outlet duct body with the same air outlet structure, and each side of the air outlet duct body is an air outlet surface with an air outlet.

[0016] As a further improvement of this utility model, a connecting plate is provided between the air inlet duct body and the air outlet duct body. The connecting plate is connected to the air outlet duct body by fasteners, and the connecting plate and the air inlet duct body are nested together.

[0017] As a further improvement of this utility model, the air outlet duct body and the connecting plate are provided with a communication port on the end face for communicating with the air inlet duct body, and the inner cavity of the air inlet duct body is connected to the inner cavity of the air outlet duct body through the communication port.

[0018] As a further improvement of this utility model, it also includes a filter screen, which is disposed in the air inlet duct body and covers the communication port.

[0019] As a further improvement to this utility model, it also includes:

[0020] A centrifugal impeller is disposed in the inner cavity of the air outlet duct body;

[0021] A drive motor is connected to the centrifugal impeller and drives it to rotate.

[0022] As a further improvement of this utility model, the air inlet end at the top of the centrifugal impeller is embedded in the communication port, and an annular air outlet cavity is formed on the outer periphery of the centrifugal impeller. After the airflow is drawn in through the air inlet end at the top of the centrifugal impeller, it diffuses radially through the annular air outlet cavity.

[0023] As a further improvement of this utility model, the inner wall of the air outlet duct body is provided with a plurality of air guide plates symmetrically distributed around the center, and the centrifugal impeller is located at the symmetrical center position of each of the air guide plates.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the cooperation between the first connection structure and the second connection structure, two air purifiers can be stacked coaxially. In the stacked state, the horizontal displacement of the air purifier located on top is effectively constrained, thereby significantly improving the connection stability of the overall structure. This design is particularly suitable for application scenarios that require multiple units to work together, and can greatly reduce the space occupied by the equipment and improve space utilization efficiency.

[0026] 2. When two air purifiers are stacked in the same direction, the roller structure of the lower air purifier can be smoothly stored in the receiving groove set in the middle of the first assembly surface of the upper air purifier, realizing structural avoidance and integration. This design not only avoids the instability caused by the rollers being exposed in the stacked state, but also effectively improves the compactness and aesthetics of the overall structure. At the same time, it reduces the risk of slippage caused by accidental contact of the rollers during transportation or movement, further enhancing the stability and safety in the stacked state.

[0027] 3. Both the air inlet and outlet are arranged around the outer perimeter of the air purifier, enabling 360° circumferential air intake and exhaust. This design ensures that the air purifier can quickly process air over a larger area, greatly improving the efficiency of air intake and exhaust, thus allowing the air purifier to fully exert its purification efficiency and improve purification efficiency.

[0028] 4. The inner wall of the air outlet duct body is provided with multiple air guide plates symmetrically distributed along the center. The long and short sides of two adjacent air guide plates are inclined and parallel to form an air guide channel. The centrifugal impeller is located at the symmetrical center of each air guide plate. This arrangement ensures that the air volume of each air guide channel is consistent, achieving a uniform ventilation effect.

[0029] 5. The tilt direction of the air guide channel matches the rotation direction of the centrifugal impeller. This means that when the impeller rotates, the airflow it generates can smoothly enter the air guide channel and be effectively guided and accelerated along the preset direction, which greatly improves the overall air output efficiency of the air purifier. In this way, not only can the consistency and stability of air flow be guaranteed, but energy loss can also be reduced and the energy efficiency ratio of the entire system can be improved.

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0039] like Figures 1-6 As shown, this utility model provides an air purifier assembly structure, including:

[0040] The first air purifier 100 includes a first air inlet duct 110 and a first air outlet duct 120 connected along the axial direction. The end face of the first air outlet duct 120 away from the first air inlet duct 110 forms a first mounting surface. The outer edge of the first mounting surface is provided with a first connecting structure, and the middle part of the first mounting surface is recessed to form a receiving groove 140.

[0041] The second air purifier 200 includes a second air inlet duct 210 and a second air outlet duct 220 that are axially connected. The two end faces of the second air inlet duct 210 and the second air outlet duct 220 that are opposite to each other form a second mounting surface. The outer edge of the second mounting surface is provided with a second connecting structure that is adapted to the first connecting structure.

[0042] The first air outlet duct 120 and the second air outlet duct 220 are respectively provided with a first roller 122 and a second roller 221;

[0043] The first air purifier 100 and the second air purifier 200 have two stacking methods:

[0044] Co-directional stacking: The first air inlet duct 110 is connected to the second air outlet duct 220. At this time, the first connecting structure and the second connecting structure form a circumferential constraint fit, and the second roller 221 is stored in the receiving groove 140.

[0045] Reverse stacking: The first air inlet duct 110 is connected to the second air inlet duct 210. At this time, the first connecting structure and the second connecting structure form a circumferential constraint fit.

[0046] It should be noted that both the first air purifier 100 and the second air purifier 200 are independent, modular units with complete air handling capabilities. Through the cooperation between the first and second connecting structures, the two air purifiers can be coaxially stacked. In this stacked state, the horizontal displacement of the upper air purifier is effectively constrained, thereby significantly improving the overall structural stability. This design is particularly suitable for applications requiring multiple units to work collaboratively, greatly reducing the space occupied by the equipment and improving space utilization efficiency.

[0047] In addition, this flexible design allows users to freely choose the combination mode according to the needs of specific application scenarios. Whether it's to optimize space layout or enhance air purification effects, the most suitable configuration can be found. Therefore, in scenarios where multiple units work together, it not only significantly reduces the equipment's footprint and improves space utilization, but also greatly enhances product adaptability and user experience.

[0048] Another noteworthy point is that the roller structure of the lower air purifier can be smoothly stored in the receiving slot 140 set in the middle of the first assembly surface of the upper air purifier, achieving structural avoidance and integration. This design not only avoids the instability caused by the rollers being exposed in the stacked state, but also effectively improves the compactness and aesthetics of the overall structure. At the same time, it reduces the risk of slippage caused by accidental contact of the rollers during transportation or movement, further enhancing the stability and safety in the stacked state.

[0049] Overall, by optimizing and improving the structural layout, connection methods, and positioning mechanisms of air purifiers, the technical shortcomings of traditional air purifiers in terms of space utilization, structural stability, and combination flexibility have been overcome. The beneficial effects include, but are not limited to:

[0050] 1. Reduce floor space and improve space utilization;

[0051] 2. Improve stacking stability and eliminate safety hazards;

[0052] 3. Improve device connection reliability and enhance user experience;

[0053] 4. Enable modular expansion to meet the needs of diverse application scenarios.

[0054] Preferably, the first connecting structure is a circumferentially extending annular groove 130, and the second connecting structure is an annular protrusion 230 that is interference-fitted with the annular groove 130. When two air purifiers are stacked one on top of the other, the annular protrusion 230 can be embedded in the annular groove 130 to achieve a tight connection between the two.

[0055] This structural design not only helps with automatic alignment and improves assembly efficiency, but also creates effective constraints in the circumferential direction to prevent relative sliding or offset between stacked devices, thereby further enhancing the stability and reliability of the overall structure.

[0056] Preferably, the second assembly surface is further provided with concentrically arranged annular ribs 240, which are spaced apart from the annular protrusions 230. When the annular protrusions 230 are embedded in the annular groove 130, the annular ribs 240 will be located exactly in the receiving groove 140 on the first assembly surface and abut against its inner edge.

[0057] This design further enhances the positioning accuracy and contact stability of the connection points, not only improving the overall structure's anti-slip capability but also effectively dispersing the stress on the connection points, preventing structural deformation or loosening caused by excessive local stress, thereby significantly improving the stability and safety of the equipment in a stacked state.

[0058] Preferably, the first air inlet duct 110 and the second air inlet duct 210 both include air inlet duct bodies with the same air inlet structure, and each side of the air inlet duct body is an air inlet surface 111 with an air inlet.

[0059] Both the first air outlet duct 120 and the second air outlet duct 220 include air outlet duct bodies with the same air outlet structure. Each side of the air outlet duct body is an air outlet surface 121 and has an air outlet.

[0060] In other words, both the air inlet and outlet are arranged circumferentially around the outer wall of the air purifier, enabling 360° circumferential air intake and exhaust. This design ensures that the air purifier can quickly process air over a larger area, greatly improving the efficiency of air intake and exhaust, and thus allowing the air purifier to fully exert its purification efficiency and improve its overall purification efficiency.

[0061] Preferably, a connecting plate 150 is provided between the air inlet duct body and the air outlet duct body. The connecting plate 150 is connected to the air outlet duct body by fasteners, and the connecting plate 150 and the air inlet duct body are nested together. This structural design not only ensures the tightness and firmness of the connection between the air inlet duct body and the air outlet duct body in a single air purifier, but also facilitates disassembly and maintenance, improves the assembly accuracy and stability of the overall structure, and provides convenience for the replacement of the filter 160 and the maintenance of internal components, thereby enhancing the practicality and maintainability of the product.

[0062] Preferably, the air outlet duct body and the connecting plate 150 have a communication port 123 on the end face for communicating with the air inlet duct body. The inner cavity of the air inlet duct body is connected to the inner cavity of the air outlet duct body through the communication port 123, ensuring that air can flow smoothly from the air inlet duct and be discharged through the air outlet duct.

[0063] Preferably, it also includes a filter screen 160, which is arranged in a cylindrical structure. Its top surface is connected to the top surface of the air inlet duct body, and the bottom surface of the filter screen 160 abuts against the connecting plate 150 and covers the vent, ensuring that all air entering the air outlet duct body must be filtered by the filter screen 160 before it can enter the inner cavity of the air outlet duct body through the vent, thereby achieving efficient air purification.

[0064] Preferred options also include:

[0065] The centrifugal impeller 170 is located in the inner cavity of the air outlet casing. It adopts a multi-blade structure design, which has good aerodynamic performance and can achieve efficient air delivery with low noise.

[0066] The drive motor 171 is connected to the centrifugal impeller 170 and drives it to rotate. It is used to drive the centrifugal impeller 170 to rotate at high speed, thereby drawing the air filtered by the filter screen 160 into the air outlet body, pressurizing it and sending it out through the air outlet.

[0067] Preferably, the air inlet end at the top of the centrifugal impeller 170 extends downward and is embedded in the communication port 123 at the top of the air outlet body, forming a continuous airflow channel. During the high-speed rotation of the centrifugal impeller 170, air is drawn in from the top air inlet end and diffuses outward under the action of centrifugal force, thus forming an annular air outlet cavity in its outer peripheral area.

[0068] The intake air is accelerated by the centrifugal impeller 170 and discharged radially outward to the annular air outlet cavity. It is then evenly delivered to the indoor space through the air outlet of the air outlet body.

[0069] The design of directly embedding the connecting port 123 at the top of the centrifugal impeller 170 minimizes the airflow path and resistance, thereby improving the fan's efficiency in drawing in filtered air. At the same time, the annular air outlet cavity, combined with the radial diffusion structure, can evenly distribute air to both sides of the air outlet duct body, increasing the air outlet area and air delivery efficiency, thus accelerating the indoor air purification speed.

[0070] Furthermore, in order to improve air output efficiency, this embodiment has multiple air guide plates 180 symmetrically distributed along the center on the inner wall of the air outlet duct body. Through its structural design, it plays an effective role in guiding air flow, ensuring that air can be discharged with the optimal path and maximum efficiency.

[0071] Specifically, the air guide plate 180 is arranged in an L-shape. The long and short sides of two adjacent air guide plates 180 are inclined and parallel to form an air guide channel 181. The impeller is located at the symmetrical center of each air guide plate 180. This arrangement ensures that the air volume of each air guide channel 181 is consistent, achieving a uniform ventilation effect.

[0072] In addition, the tilt direction of the air guide channel 181 matches the rotation direction of the centrifugal impeller 170. This means that when the centrifugal impeller 170 rotates, the airflow it generates can smoothly enter the air guide channel 181 and be effectively guided and accelerated along the preset direction, which greatly improves the overall air output efficiency of the air purifier. In this way, not only can the consistency and stability of air flow be guaranteed, but energy loss can also be reduced and the energy efficiency ratio of the entire system can be improved.

The above are specific embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.

If the specific posture changes, the directional indicator will also change accordingly.
