[0002] Current air purifiers usually use non-biological filter materials to filter air impurities, which have average adsorption and purification effects and cannot produce fresh oxygen. With the development of air purification technology, researchers have found that biological filter materials (such as mosses such as gourd moss, white moss, golden moss, large gray moss, and large feather moss) have excellent air purification and filtration performance, which can replace the non-biological filter materials in the existing technology, making air purifiers have better air purification effects.

[0003] Although the use of biological filtration materials can achieve better filtration effects, compared with non-biological filtration materials, the lifespan of mosses is limited. Therefore, in actual use, the mosses in the purifier need to be regularly maintained, that is, when the mosses reach the end of their service life, they should be removed from the purifier and fresh mosses should be placed in order to ensure the purification performance of the biological filtration materials.

DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Please also read Figures 1 to 7 The air purification device provided by the present application is now described. The air purification device provided by the present application comprises a fixing seat 1, a rotating motor 2, a culture tray 3 and a top cover 4.

[0040] The fixing seat 1 is used to be placed in an air circulation area, and has a ventilation cavity 11 penetrating its upper surface, and a plurality of through holes 12 are arranged on the outer peripheral wall, which are distributed at intervals along the circumference of the fixing seat 1 and are all connected to the ventilation cavity 11.

[0041] The rotating motor 2 is fixedly connected to the bottom surface of the ventilation cavity 11, and its power output axis is parallel to the up-down direction. A slot 21 is provided on the power output end surface, and the cross section of the slot 21 is a polygon.

[0042] The culture tray 3 is suitable for being arranged in the ventilation cavity 11, and has a biological filter material 31 on its upper surface. In the present embodiment, the biological filter material 31 is usually selected from mosses such as gourd moss, white moss, golden moss, large gray moss, and large feather moss.

[0043] The lower surface of the culture tray 3 is connected with a positioning rod 32 suitable for being inserted into the slot 21 from top to bottom, and the positioning rod 32 adopts a prism structure adapted to the slot 21; in this embodiment, the slot 21 is a hexagonal slot, and the positioning rod 32 adopts a hexagonal prism structure.

[0044] The top cover 4 is adapted to be detachably connected to the fixing base 1 to close the opening of the ventilation cavity 11. Specifically, the lower surface of the top cover 4 has a rubber ring adapted to be embedded in the top of the fixing base 1. The top cover 4 is provided with a light-transmitting port 41 to allow an external light source to pass through and illuminate the surface of the biological filter material 31 to ensure the activity of the biological filter material 31.

[0045] In the embodiment of the present application, outside air enters the ventilation cavity 11 through the through hole 12 and contacts the biological filter material 31 to complete air purification; during this process, the rotating motor 2 and the culture plate 3 cooperate to realize the rotation of the biological filter material 31 in the horizontal plane, thereby ensuring the contact between the biological filter material 31 and the air inside the ventilation cavity 11, thereby improving the air filtering efficiency of the biological filter material 31.

[0046] When maintaining the air purification device, the biological filter material 31 needs to be taken out and replaced. At this time, the top cover 4 can be removed from the fixing seat 1, and then the culture tray 3 can be manually taken out from bottom to top to separate the positioning rod 32 and the slot 21; after replacing the biological filter material 31 on the surface of the culture tray 3, the culture tray 3 can be placed back into the ventilation cavity 11.

[0047] Compared with the prior art, the air purification device provided in this embodiment shortens the time required for replacing the biological filter material 31, and the efficiency of regular maintenance of the biological filter material 31 is guaranteed.

[0048] In some embodiments, see Figure 3 The air purification device further includes a plurality of locking assemblies 5 . In the present embodiment, there are two locking assemblies 5 , and the two locking assemblies 5 are spaced apart along the circumference of the fixing seat 1 .

[0049] Each locking assembly 5 is used to extend into the ventilation cavity 11 and connect with the culture tray 3 to limit the movement of the culture tray 3 in the up and down directions, thereby avoiding the separation of the culture tray 3 and the rotating motor 2 and improving the structural stability of the device.

[0050] In some embodiments, the above-mentioned characteristic locking component 5 can be used as follows Figure 3 and Figure 7 See the structure shown. Figure 3 and Figure 7 The locking assembly 5 includes a translation rod 51 and two locking arms 52 .

[0051] The translation rod 51 is arranged to penetrate the fixed seat 1 in the horizontal direction, and one end of the translation rod 51 is suitable for being inserted into the ventilation cavity 11, and the other end is suitable for being extended to the outside of the fixed seat 1; wherein, one end of the translation rod 51 suitable for being inserted into the ventilation cavity 11 is connected with a translation plate 511, and when the translation rod 51 moves toward the ventilation cavity 11, the translation plate 511 is suitable for abutting the outer peripheral wall of the culture dish 3.

[0052] The two locking arms 52 are arranged in parallel on the side of the translation plate 511 suitable for abutting the culture tray 3; when the translation rod 51 is manually rotated, the two locking arms 52 can rotate to positions distributed in the up and down directions.

[0053] In actual use, manually moving the translation rod 51 toward the ventilation cavity 11 can make the translation plate 511 abut against the culture tray 3, and the two locking arms 52 are respectively located on the upper and lower sides of the culture tray 3 to limit the movement of the culture tray 3 in the up and down directions, thereby improving the structural stability of the device.

[0054] In some embodiments, the above-mentioned characteristic translation plate 511 and the inner peripheral wall of the ventilation cavity 11 can be connected by the following method: Figure 6 See the structure shown. Figure 6 A return spring 512 is provided between the translation plate 511 and the inner peripheral wall of the ventilation cavity 11 , and the return spring 512 is sleeved on the outer periphery of the translation rod 51 .

[0055] When the translation plate 511 abuts against the culture tray 3, the return spring 512 is in a normal state or an elastically contracted state, thereby preventing the translation plate 511 and the culture tray 3 from separating, thereby achieving the technical effect of improving the stability of the locking assembly 5 during use.

[0056] In some embodiments, the above-mentioned characteristic translation rod 51 can be used as follows Figure 6 See the structure shown. Figure 6 One end of the translation rod 51 that is adapted to extend outward from the fixing seat 1 is connected to a limiting plate 513 , and the limiting plate 513 extends outward in the radial direction of the translation rod 51 .

[0057] In actual use, the limiting plate 513 is suitable for abutting against the outer wall of the fixing seat 1 to limit the movement of the translation rod 51 toward the ventilation cavity 11, thereby improving the stability of the device in use.

[0058] It should be noted that the side of the limit plate 513 facing away from the fixing seat 1 has a handle for manual gripping to improve stability during manual control. In addition, the outer wall of the fixing seat 1 is integrally connected with a planar structure for the limit plate 513 to abut against, thereby increasing the contact area with the fixing seat 1 and improving the structural stability of the connection between the fixing seat 1 and the limit plate 513.

[0059] In some embodiments, the distance between the two locking arms 52 is equal to the thickness of the culture tray 3, so that the two locking arms 52 can achieve a clamping effect when they are located on both sides of the culture tray 3, thereby achieving the technical effect of simultaneously limiting the up and down movement of the culture tray 3, thereby improving the structural stability of the device.

[0060] In some embodiments, the inner wall of the above-mentioned characteristic ventilation cavity 11 and the culture plate 3 can be connected by the following method: Figure 3See the structure shown. Figure 3 A plurality of germicidal lamps 6 are connected to the inner peripheral wall of the ventilation cavity 11 , and the plurality of germicidal lamps 6 are arranged at intervals around the culture tray 3 ; in the present embodiment, there are two germicidal lamps 6 , which are respectively arranged in the space between the two locking components 5 .

[0061] When the positioning rod 32 is inserted into the slot 21 , each germicidal lamp 6 is used to irradiate the biological filter material 31 to eliminate bacteria on the surface of the biological filter material 31 , thereby extending the service life of the biological filter material 31 .

[0062] In some embodiments, the above-mentioned characteristic slot 21 and culture plate 3 can be used as follows Figure 5 See the structure shown. Figure 5 The slot 21 is coaxially arranged with the power output shaft of the rotating motor 2, and the culture tray 3 is coaxially arranged with the positioning rod 32; the above two features are combined to achieve the coaxial positional relationship between the culture tray 3 and the power output shaft of the rotating motor 2, thereby ensuring the rotation of the biological filtration material 31 and reducing the space occupied by the rotation trajectory of the culture tray 3.

[0063] In some embodiments, the above-mentioned characteristic top cover 4 can be adopted as follows Figure 4 See the structure shown. Figure 4 A light-transmitting plate 42 suitable for closing the light-transmitting opening 41 is connected to the top cover 4, and the light-transmitting plate 42 is made of a light-transmitting material, thereby ensuring that foreign impurities are prevented from entering the ventilation cavity 11 from top to bottom without affecting the light-transmitting effect, thereby improving the stability of the device during use.

[0064] In some embodiments, the above-mentioned characteristic top cover 4 can be adopted as follows Figure 2 See the structure shown. Figure 2 The lower surface of the top cover 4 is connected with a fill light 43 for irradiating the biological filter material 31; in the present embodiment, the fill light 43 adopts a ring structure and is arranged around the light-transmitting opening 41, and the light emission direction of the fill light 43 is toward the biological filter material 31 to ensure the biological activity of the biological filter material 31.

[0065] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
