Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to an air purifier duct structure. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. They are mainly divided into household, commercial, industrial, and building types.

[0003] Existing air purifiers have a fixed air outlet direction, making it inconvenient to change the air outlet direction. Therefore, there is a need for an air purifier duct structure that allows for easy adjustment of the air outlet direction in order to solve the problems mentioned above. Utility Model Content

[0004] To address this issue, this invention provides an air purifier duct structure that, through the cooperation of a connecting seat assembly and an air duct assembly, solves the problem of a fixed air outlet duct direction in air purifiers, which cannot be changed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air purifier duct structure, comprising an air purifier body, a connecting seat assembly at the top of the air purifier body, a duct assembly at the top of the connecting seat assembly, an air purifier device in the air purifier body, an air purifier outlet at the top of the air purifier device, a connecting seat assembly including a connecting seat, a cross bracket fixedly disposed inside the connecting seat, a fixing post fixedly inserted inside the cross bracket, a retaining ring fixedly disposed at the top of the fixing post, a limiting block fixedly disposed at the top of the retaining ring, and a duct assembly including a hood, air duct outlets on both sides of the hood, a guide plate fixedly disposed inside the hood, a spring connected inside the guide plate, a connecting ring inside the guide plate, and connecting plates fixedly disposed at both ends of the connecting ring.

[0006] Preferably, the connecting seat is fixedly disposed on the top of the air purifier device and connected to the air outlet of the air purifier.

[0007] Preferably, the bottom of the air guide plate is sleeved on the outside of the fixed column and slidably connected to the fixed column.

[0008] Preferably, the bottom of the air guide plate is in contact with the cross bracket.

[0009] Preferably, the bottom of the spring is slidably connected to the air guide plate, the top of the spring is fixedly connected to the retaining ring, and the spring is sleeved on the outside of the air guide plate.

[0010] Preferably, the connecting ring is sleeved outside the limiting block and slidably connected to the limiting block.

[0011] Preferably, the bottom of the connecting plate is fixedly connected to the air guide plate.

[0012] The present invention has the following advantages:

[0013] 1. When it is necessary to change the direction of the air duct, lift the air cover. When the air cover moves upward, the connecting plate will drive the connecting ring to move upward through the air guide plate, so that the connecting ring will disengage from the limit block. At the same time, when the air guide plate moves upward, it will cooperate with the fixed baffle ring to cause the spring to contract. Then rotate the air cover to change the direction of the air outlet of the air duct, so as to facilitate the change of the direction of the air duct.

[0014] 2. After the direction adjustment is completed, loosen the fan cover. The spring force and the weight of the air duct assembly itself will cause the fan cover to move downward and contact the connecting seat, so that the connecting ring will be put back on the top of the limit block to prevent the fan cover from rotating under natural conditions and ensure the stability of the air outlet direction after the air duct direction is changed.

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1 - Appendix Figure 6 This utility model provides an air purifier duct structure, including an air purifier body 1, a connecting seat assembly 2 on the top of the air purifier body 1, and a duct assembly 3 on the top of the connecting seat assembly 2. The air purifier body 1 includes an air purifier device 11, and an air purifier outlet 12 is opened on the top of the air purifier device 11. The connecting seat assembly 2 includes a connecting seat 21, a cross bracket 22 is fixedly provided inside the connecting seat 21, a fixing post 23 is fixedly inserted inside the cross bracket 22, a retaining ring 24 is fixedly provided on the top of the fixing post 23, and a limiting block 25 is fixedly provided on the top of the retaining ring 24. The duct assembly 3 includes a hood 31, air duct outlets 32 are opened on both sides of the hood 31, a guide plate 33 is fixedly provided inside the hood 31, a spring 34 is connected inside the guide plate 33, a connecting ring 35 is provided inside the guide plate 33, and a connecting plate 36 is fixedly provided at both ends of the connecting ring 35.

[0026] In this embodiment, in order to change the direction of the air outlet duct, when it is necessary to change the direction of the duct, lift the hood 31. When the hood 31 moves upward, the connecting plate 36 drives the connecting ring 35 to move upward through the air guide plate 33, so that the connecting ring 35 is disengaged from the limiting block 25. At the same time, when the air guide plate 33 moves upward, it cooperates with the fixed baffle ring 24 to cause the spring 34 to contract. Then rotate the hood 31 to change the orientation of the air outlet 32 ​​of the duct, so as to facilitate the change of the direction of the duct.

[0027] In order to achieve the purpose of blowing out purified air, the device adopts the following technical solution: the connecting seat 21 is fixedly installed on the top of the air purifier device 11 and connected to the air purifier outlet 12. The connecting seat 21 is fixed on the top of the air purifier device 11 by existing technology and connected to the air purifier outlet 12. The air purifier device 11 blows out the purified air through the air purifier outlet 12. The blown out purified air is blown towards the air duct outlet 32 ​​through the inclined structure at the bottom of the air guide plate 33, and then the purified air is blown out through the air duct outlet 32.

[0028] To facilitate the fixing of the hood 31 after adjusting the air duct direction, the device employs the following technical solution: the bottom of the air guide plate 33 is fitted around the outside of the fixed column 23 and slidably connected to the fixed column 23; the bottom of the air guide plate 33 is in contact with the cross bracket 22; the bottom of the spring 34 is slidably connected to the air guide plate 33; the top of the spring 34 is fixedly connected to the retaining ring 24; the spring 34 is fitted around the outside of the air guide plate 33; the connecting ring 35 is fitted around the outside of the limiting block 25 and slidably connected to the limiting block 25; and the bottom of the connecting plate 36 is fixedly connected to the air guide plate 33. After the direction adjustment is completed, the hood 31 is released, and the elastic force of the spring 34 and the weight of the air duct assembly 3 itself cause the hood 31 to move downward and contact the connecting seat 21, thereby causing the connecting ring 35 to be fitted around the top of the limiting block 25 again, preventing the hood 31 from rotating naturally and ensuring the stability of the direction in which the air outlet 32 ​​faces after changing the air duct direction.

[0029] The usage process of this utility model is as follows: When using this utility model, the connecting seat 21 is fixed to the top of the air purifier device 11 using existing technology and connected to the air purifier outlet 12. The air purifier device 11 blows purified air out through the air purifier outlet 12. The blown purified air is blown towards the air duct outlet 32 ​​through the inclined structure at the bottom of the air guide plate 33, and then the purified air is blown out through the air duct outlet 32. When it is necessary to change the direction of the air duct, the fan cover 31 is lifted. When the fan cover 31 moves upward, the connecting plate 36 drives the connecting ring 35 to move upward through the air guide plate 33, so that... When the connecting ring 35 disengages from the limiting block 25, and the air guide plate 33 moves upward, it works with the fixed retaining ring 24 to cause the spring 34 to contract. Then, the fan cover 31 is rotated, thereby changing the orientation of the air outlet 32 ​​of the air duct, so as to facilitate the change of the air duct direction. After the direction adjustment is completed, the fan cover 31 is released. The elastic force of the spring 34 and the weight of the air duct assembly 3 itself cause the fan cover 31 to move downward and contact the connecting seat 21, thereby causing the connecting ring 35 to be put back on the top of the limiting block 25, preventing the fan cover 31 from rotating under natural conditions, and ensuring the stability of the orientation of the air outlet 32 ​​of the air duct after changing the air duct direction.

[0030] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
