Description

Technical Field

[0001] This application relates to the field of air purifiers, and more particularly to an air duct assembly and an air purifier. Background Technology

[0002] In the field of air purifiers, the dual-duct design has attracted widespread attention due to its ability to improve air processing efficiency per unit time. In existing technologies, this type of structure typically uses a central partition to divide the purification chamber into two independent air ducts, with fan assemblies and filter modules installed on either side of the partition. While this layout can achieve parallel airflow purification, it has significant drawbacks in actual manufacturing and assembly processes.

[0003] The two duct housings need to be fixed to the two sides of the partition with screws or clips, which is a complicated installation process involving multiple operations such as component positioning, alignment and locking, which greatly increases the labor cost of the production line. The fit tolerance between the partition and the duct housing needs to be controlled within a very small range. If there is a slight misalignment or gap, it will lead to airflow leakage or crosstalk between ducts, which will significantly reduce the purification efficiency. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an air duct assembly and purifier.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A duct assembly, comprising: The bracket includes a mounting component, which has a first surface and a second surface. Air guides are provided at both edges of the first surface and both edges of the second surface, and the air guides are integrally formed with the mounting component. A cover is disposed on two air guides on the same side of the mounting component. The mounting component, the air guides, and the cover form an airflow channel, which has an air inlet and at least one air outlet. An airflow drive assembly is disposed in the airflow channel. The airflow drive assembly has an air inlet and an air outlet. The air inlet faces the air inlet of the airflow channel, and the air outlet faces the air outlet of the airflow channel.

[0006] Furthermore, the cover includes a plate detachably connected to the air guide, the plate having a grille forming the air inlet, the plate being recessed inward along the air inlet direction to form a guide surface, and the grille being disposed on the guide surface.

[0007] Furthermore, the air guide is provided with a plurality of first locking blocks on its periphery, and the plate is provided with a plurality of second locking blocks on its periphery, the second locking blocks being engaged and connected with the first locking blocks corresponding to their positions.

[0008] Furthermore, the plate is provided with a plurality of connecting seats on its periphery, each connecting seat having a first connecting hole, and the air guide is provided with a plurality of connecting plates, each connecting plate having a second connecting hole. The first connecting hole and the second connecting hole form a connecting channel, and a fastener is provided in the connecting channel.

[0009] Furthermore, the first surface and / or the second surface are provided with a first rib.

[0010] Furthermore, a reinforcing plate is provided on the first surface and / or the second surface, and a plurality of fastening blocks are provided around the reinforcing plate. The mounting component is provided with a fastening groove, and the fastening block is fastened and connected to the fastening groove.

[0011] Furthermore, a second rib is provided on the side of the reinforcing plate facing the mounting component.

[0012] Furthermore, the airflow drive assembly includes a rotary drive assembly and a fan wheel. The rotary drive assembly has a rotating shaft, and the fan wheel is disposed on the rotating shaft. The rotary drive assembly includes a rotary drive component, and a plurality of support arms are disposed on the rotary drive component. The support arms are fixedly connected to the mounting component, and each support arm is provided with a shock-absorbing pad at the connection between it and the mounting component.

[0013] Furthermore, the wind turbine includes a first disk and a second disk spaced apart from each other. The first disk has a central hole facing the air inlet. The second disk is fixedly connected to the rotating shaft. A plurality of fan blades are connected between the first disk and the second disk at intervals.

[0014] This application also provides a purifier that includes the air duct assembly described in any one of the above descriptions.

[0015] This application eliminates the assembly gap between the partition and the duct housing by integrating the mounting parts and air guides of the bracket, thus solving the problem of airflow leakage or crosstalk between ducts caused by misalignment during installation. This significantly improves purification efficiency. Furthermore, the cover is directly assembled onto the two air guides on the same side of the bracket to form an airflow channel, simplifying the installation process of the dual-duct structure and avoiding the cumbersome operation of fixing two independent duct housings separately in the prior art, effectively reducing production time and costs.

[0025] This application provides a duct assembly having a first direction X, a second direction Y, and a third direction Z. The duct assembly includes a bracket 100, a cover 200, and an airflow drive assembly 300. Specifically, the bracket 100 includes a mounting member 110, which has a first surface and a second surface. Air guides 120 are provided at both edges of the first surface and both edges of the second surface. The air guides 120 are integrally formed with the mounting member 110. The cover 200 is disposed on the two air guides 120 on the same surface of the mounting member 110. The mounting member 110, the air guides 120, and the cover 200 surround to form an airflow channel 130. The airflow channel 130 has an air inlet and at least one air outlet. The airflow drive assembly 300 is disposed in the airflow channel 130 and has an air intake port and an air exhaust port. The air intake port faces the air inlet of the airflow channel 130, and the air exhaust port faces the air outlet of the airflow channel 130.

[0026] Please see Figures 1 to 3 As shown, the third direction is the height direction, the first surface is the upper surface of the mounting component 110, and the second surface is the lower surface of the mounting component 110. In order to prevent air leakage caused by gaps between the air duct housing and the partition due to installation errors during the installation process, thereby reducing the purification efficiency of the purifier, this application directly integrates the mounting component 110 and the air guide component 120 into one piece, thereby avoiding gaps at the connection between the two and causing air leakage. It can be understood that the mounting component 110 is a partition, the air guide component 120 is an air duct housing, and the mounting component 110 and the air guide component 120 can be made of plastic. The two are integrally molded using injection molding process.

[0027] Furthermore, air guides 120 are provided at both sides of the upper surface of the mounting member 110 along the second direction and at both sides of the lower surface of the mounting member 110 along the second direction. Two air guides 120 on each side of the mounting member 110 are detachably connected to the cover 200. In this case, the cover 200, the mounting member 110, and the two air guides 120 define an airflow channel 130 for gas flow. That is, both the upper and lower surfaces of the mounting member 110 have airflow channels 130, thus achieving a dual airflow path. It is understood that, in order to discharge airflow, the airflow channel 130 must have at least one outlet. In this embodiment, the airflow channel 130 has two outlets along the first direction, allowing exhaust from both outlets simultaneously.

[0028] Both airflow channels 130 are equipped with airflow drive components 300 for gas flow. External gas enters the airflow drive component 300 through the air inlet of the airflow channel 130, and then the airflow drive component 300 is activated to transport the gas through the air outlet of the airflow drive component 300 to the air outlet of the airflow channel 130 for discharge, thereby realizing gas transport.

[0029] In some embodiments, the cover 200 includes a plate 210 detachably connected to the air guide 120. The plate 210 is provided with a grille 230 to form an air inlet. The plate 210 is recessed in the air inlet direction to form a guide surface 220, and the grille 230 is disposed on the guide surface 220.

[0030] Please see Figure 4 and Figure 5 As shown, the grille 230 has air inlet gaps, and multiple air inlet gaps form an air inlet. External gas is drawn into the airflow drive assembly 300 through the air inlet formed by the grille 230. In order to allow more gas to be drawn into the airflow drive assembly 300, the cover 200 is recessed in the center towards the air outlet of the airflow drive assembly 300 to form a guide surface 220. The guide surface 220 guides the gas, giving the gas a larger air inlet area, and the air inlet gaps of the grille 230 allow the gas to enter the airflow drive assembly 300 evenly.

[0031] The grille 230 is designed to protrude outwards in a direction away from the airflow drive component 300. This is to create a certain gap between it and the air inlet of the airflow drive component 300, so that the air intake is more uniform and the noise generation is reduced.

[0032] In some embodiments, the air guide 120 is provided with a plurality of first locking blocks 121 around its periphery, and the plate 210 is provided with a plurality of second locking blocks 211 around its periphery, and the second locking blocks 211 are engaged and connected with the first locking blocks 121 corresponding to their positions.

[0033] See Figure 1 , Figure 3 , Figure 4 In order to connect the plate 210 and the air guide 120 and fix their positions, they are connected by a snap-fit ​​method. Specifically, multiple second snap blocks 211 are provided on the periphery of the plate 210, and correspondingly, a first snap block 121 that matches the position of the second snap blocks 211 is provided on the periphery of the air guide 120. When the plate 210 and the air guide 120 are installed together, the connection can be achieved simply by engaging the second snap block 211 with the first snap block 121 corresponding to its position.

[0034] In some embodiments, a plurality of connecting seats 212 are provided around the plate 210, each connecting seat 212 having a first connecting hole. A plurality of connecting plates 122 are provided on the air guide 120, each connecting plate 122 having a second connecting hole. The first connecting hole and the second connecting hole form a connecting channel, and a fastener is provided in the connecting channel.

[0035] Please continue reading. Figure 1 , Figure 3 as well as Figure 4As shown, since the second locking block 211 is fastened to the first locking block 121, the connection between the plate 210 and the air guide 120 still carries the risk of separation. For example, vibration during handling and transportation may cause the second locking block 211 to separate from the first locking block 121.

[0036] To further improve the connection strength between plate 210 and air guide 120, multiple connecting plates 122 are provided on the peripheral side of air guide 120, and connecting seats 212 are provided at corresponding positions on the peripheral side of plate 210. When the second locking block 211 and the first locking block 121 are engaged to connect plate 210 and air guide 120, the first connecting hole of connecting seat 212 and the second connecting hole of connecting plate 122 are coaxially connected. Then, fasteners are inserted through the second connecting hole to the first connecting hole to achieve the connection between connecting plate 122 and connecting seat 212, further ensuring the connection strength between air guide 120 and plate 210.

[0037] For example, the fastener can be a screw, that is, the screw passes through the second connecting hole and connects to the first connecting hole, thereby improving the connection strength between the air guide 120 and the plate 210 by connecting the connecting plate 122 and the connecting seat 212.

[0038] In some embodiments, the first and / or second surfaces of the mounting member 110 are provided with first ribs 140.

[0039] In another embodiment, the first rib 140 is disposed on the lower surface of the mounting member 110.

[0040] In another embodiment, the first rib 140 is respectively disposed on the upper surface and the lower surface of the mounting member 110.

[0041] Please see Figure 2 As shown, in this embodiment, in order to prevent the mounting component 110 from undergoing large deformation due to load or force, a first rib 140 is provided on the upper surface of the mounting component 110 to improve its overall strength and reduce the deformation of the mounting component 110.

[0042] Furthermore, there are multiple first ribs 140, and these multiple first ribs 140 can be arranged in an alternating or parallel manner on the mounting component 110.

[0043] In some embodiments, a reinforcing plate 160 is provided on the first and / or second surfaces, and a plurality of fasteners 161 are provided around the reinforcing plate 160. A fastening groove 150 is provided on the mounting member 110, and the fasteners 161 are fastened to the fastening groove 150.

[0044] Please see Figure 2 , Figure 3 as well as Figure 6As shown, in order to further improve the overall strength of the mounting component 110, a reinforcing plate 160 is provided on the side where the first rib 140 is provided, so that the reinforcing plate 160 is fixedly connected to the mounting component 110. It can be understood that the reinforcing plate 160 can not only cover the first rib 140, but also combine with the mounting component 110 to improve its overall strength, thereby further improving the deformation resistance of the mounting component 110.

[0045] In order to connect the reinforcing plate 160 with the mounting part 110, a certain number of fasteners 161 are provided on the periphery of the reinforcing plate 160. Similarly, fastening grooves 150 that are adapted to the position and shape of the fasteners 161 can be provided on the mounting part 110. During installation, the connection between the reinforcing plate 160 and the mounting part 110 can be achieved simply by fastening the fasteners 161 with the fastening grooves 150, and the first rib 140 can be covered.

[0046] In some embodiments, a second rib 162 is provided on the side of the reinforcing plate 160 facing the mounting member 110.

[0047] Please see Figure 6 As shown, in order to improve the deformation resistance of the reinforcing plate 160, a number of second ribs 162 are provided on the side of the reinforcing plate 160 facing the first rib 140. The deformation resistance of the reinforcing plate 160 is improved by the interlacing or parallel arrangement of the number of second ribs 162, thereby further improving the deformation resistance of the mounting part 110.

[0048] In some embodiments, the airflow drive assembly 300 includes a rotary drive assembly 310 and a fan wheel 320. The rotary drive assembly 310 has a rotating shaft, and the fan wheel 320 is disposed on the rotating shaft. The rotary drive assembly 310 includes a rotary drive member 311, and a plurality of support arms 312 are disposed on the rotary drive member 311. The support arms 312 are fixedly connected to the mounting member 110, and a shock-absorbing pad 313 is disposed at the connection between each support arm 312 and the mounting member 110.

[0049] Please see Figure 1 , Figure 2 as well as Figure 7 As shown, multiple support arms 312 are provided on the bottom circumference of the rotary drive component 311 for support. The support arms 312 are then fixedly connected to the mounting component 110. Specifically, the support arms 312 can be fixedly connected to the mounting component 110 with screws to complete the installation. In order to prevent the rotary drive component 311 from generating noise due to vibration during rotation, a shock-absorbing pad 313 is provided at the connection between the support arm 312 and the mounting component 110 for shock absorption and noise reduction.

[0050] For example, the rotary drive 311 is a motor or electric motor, and the shock absorber 313 can be a rubber pad.

[0051] In some embodiments, the impeller 320 includes a first impeller 321 and a second impeller 322 that are spaced apart from each other. The first impeller 321 has a central hole facing the air inlet. The second impeller 322 is fixedly connected to the rotating shaft. A plurality of fan blades 323 are connected between the first impeller 321 and the second impeller 322.

[0052] Please see Figure 2 , Figure 5 , Figure 8 as well as Figure 9 As shown, the second disc 322 is connected to the rotary drive 311, thereby driving the wind turbine 320 to rotate as a whole. The fan blades 323 rotate to discharge gas from the center hole of the first disc 321 to the air outlet of the airflow channel 130, thus realizing the driving gas delivery.

[0053] The second wheel 322 is recessed from the edge to the center in the direction away from the rotating drive member 311, thereby accommodating the rotating drive member 311, reducing the distance between the second wheel 322 and the mounting member 110, and reducing the space occupied by the rotating drive member 311.

[0054] like Figure 5 and Figure 8 As shown, the plate 210 is recessed at the center of the side facing the first wheel 321 to form an annular groove 213. The first wheel 321 has an annular arc surface. The edge of the arc surface near the central hole extends towards the groove 213 to form an extension. The extension is located inside the groove 213, so that the external gas can fully enter the interior of the impeller 320, and to a certain extent, it can also reduce the space occupied by the entire impeller 320 and save space.

[0055] This application also provides a purifier that includes the air duct assembly of any of the above.
