Description

Technical Field

[0001] The present invention relates to the field of air purification, in particular to a rotor-type air purifier. Background Art

[0002] In air purifiers, catalytic decomposition is a common technique for removing harmful chemical gaseous pollutants from the air. For example, photocatalytic decomposition technology is used for air purification. The principle is that when exposed to light, photocatalysts generate holes and electron pairs on their surface. When water molecules in the air come into contact with these holes, hydroxyl radicals are rapidly generated and attached to the surface. These hydroxyl radicals act as strong oxidants, breaking down harmful chemical gaseous pollutants in the air and producing harmless water and carbon dioxide. Hydroxyl radicals can also coagulate viral proteins and destroy bacterial cell walls, thereby purifying the air.

[0003] This type of air purifier typically attaches a catalyst to a substrate surface. To function effectively, the air must be in full contact with the catalyst. Therefore, the air must be flowing, and the wind speed should not be too fast to ensure sufficient reaction time between the gaseous pollutants and the hydroxyl radicals. However, large-scale air purification requires high air flow and high wind speed, and the physical structure of such a purifier must also be large to meet the air purification efficiency requirements. This makes the purification device expensive, energy-intensive, and space-consuming, significantly limiting its widespread application. Summary of the Invention

[0034] like Figures 1 to 6 As shown, an embodiment of the present invention provides a rotor-type air purifier, comprising a shell 100 and a reactor 106; wherein, an installation space is formed in the shell 100, and a first air inlet 102 and a first air outlet 104 communicating with the installation space are provided on the shell 100; the reactor 106 is rotatably arranged in the installation space, a catalyst layer 108 is provided inside the reactor 106, and a second air inlet 110 communicating with the first air inlet 102 and a second air outlet 112 communicating with the first air outlet 104 are provided on the reactor 106; a light source array is also provided at a position corresponding to the reactor 106 in the shell 100.

[0035] The rotor type air purifier provided in the embodiment of the present invention is provided with an installation space in the housing 100, a rotatable reactor 106 is provided in the installation space, and a second air inlet 110 and a second air outlet 112 are provided on the reactor 106, so that after the external air flows into the reactor 106, the circulation time in the reactor 106 becomes longer accordingly. Moreover, under the action of the flowing air, the reactor 106 rotates with the flow of the air, so that the relative flow time of the air flow in the reactor 106 is longer, the reaction is more complete, and there is no need to provide an additional driving device. By arranging a catalyst layer 108 inside the reactor 106 and arranging a light source array at a position corresponding to the reactor 106 in the housing 100, the harmful chemical gaseous pollutants in the air can be decomposed by the reaction of the light source array and the catalyst layer 108, and harmless water and carbon dioxide are generated after the reaction, thereby achieving purification of the air. At the same time, since the circulation time of the air in the reactor 106 becomes longer, the rotor type air purifier can purify a large amount of air.

[0036] Specifically, a support leg 132 is provided at the bottom of the housing 100 to support the rotor-type air purifier.

[0037] An installation space is formed inside the housing 100, and a first air inlet 102 and a first air outlet 104 are formed on the housing 100, communicating with the installation space. The first air inlet 102 is formed on the side of the housing 100, and the first air outlet 104 is formed on the top of the housing 100.

[0038] The reactor 106 is installed in the installation space inside the shell 100 to purify the air. The reactor 106 is rotatably connected to the shell 100, that is, the reactor 106 can be a rotor-type reactor 106. A second air inlet 110 is formed at a position corresponding to the first air inlet 102 on the reactor 106, and a second air outlet 112 is formed at a position corresponding to the first air outlet 104. That is, external air can enter the shell 100 through the first air inlet 102, and then enter the reactor 106 through the second air inlet 110. After being reacted and purified in the reactor 106, it flows out of the shell 100 through the second air outlet 112 and the first air outlet 104 in sequence. In this way, when air flows in, the friction between the air and the reactor 106 can cause the reactor 106 to rotate, and there is no need to set up an additional driving device to drive the reactor 106.

[0039] In order to purify the air, a catalyst layer 108 is provided inside the reactor 106, and a light source array is provided at a position corresponding to the reactor 106 in the shell 100. The catalyst layer 108 is irradiated by the light source array, so that electron-hole pairs can be excited on the surface of the catalyst layer 108. When it comes into contact with water molecules in the flowing air, hydroxyl radicals, a strong oxidant, are immediately generated on its surface. As long as the irradiation of the light source array is not interrupted and there is flowing air, hydroxyl radicals will adhere to its surface, which will continuously produce oxidative decomposition effects on harmful gases in the air, and generate harmless water and carbon dioxide after the reaction.

[0040] According to one embodiment of the present invention, a spiral air duct 114 is formed inside the reactor 106 . The second air inlet 110 and the second air outlet 112 are both connected to the air duct 114 , and the catalyst layer 108 is bonded inside the air duct 114 .

[0041] See also Figure 6 By setting the air duct 114 inside the reactor 106 into a spiral shape, the air flows in the spiral air duct 114 of the reactor 106. Due to the friction resistance between the air flow and the inner wall of the spiral air duct 114, the air flow forms a vortex in the spiral air duct 114 and rolls forward continuously. During the forward process, the hydroxyl free radicals on the inner wall of the air duct 114 will oxidize and decompose the harmful gaseous pollutants in the air flow.

[0042] According to one embodiment of the present invention, a rotating shaft 116 is provided at the bottom of the reactor 106 , and a support platform and a bearing 118 for passing the rotating shaft 116 are provided on the shell 100 . The rotating shaft 116 abuts against the supporting platform after passing through the bearing 118 .

[0043] like Figures 1 to 3 As shown, the reactor 106 is rotatably connected to the housing 100 via a rotating shaft 116, wherein the rotating shaft 116 is connected to the rotation center of the reactor 106, thereby ensuring the stability of the reactor 106 during rotation. In addition, to achieve stable support for the rotating shaft 116, a support platform is provided on the housing 100. One end of the rotating shaft 116 is fixedly connected to the reactor 106, and the other end of the rotating shaft 116 abuts the support platform. To reduce the rotational friction between the rotating shaft 116 and the housing 100, a bearing 118 is also provided on the housing 100. The bearing 118 can be an oil-containing bearing 118, and the rotating shaft 116 extends through the bearing 118.

[0044] Please continue to see Figures 1 to 3 According to one embodiment of the present invention, the support platform includes a connecting section 120 and a supporting plate 122. One end of the connecting section 120 is integrally formed at the bottom of the shell 100. The supporting plate 122 is connected to the other end of the connecting section 120. The rotating shaft 116 abuts against the supporting plate 122.

[0045] The support platform includes a connecting section 120 and a support plate 122. The connecting section 120 is used to support the support plate 122. Specifically, the first end of the connecting section 120 can be integrally formed with the housing 100, and the second end of the connecting section 120 is perpendicularly connected to the support plate 122 to form an L-shaped support platform. The first end of the connecting section 120 is connected to the housing 100 and extends away from the housing 100. It should be noted that the length of the connecting section 120 is less than the length of the legs 132.

[0046] See also Figure 1 According to one embodiment of the present invention, the first air inlet 102 includes a plurality of air inlet holes, which are arranged at intervals on the shell 100; the second air inlet 110 is arranged on the side wall of the reactor 106; and a fan 124 is also arranged between the plurality of air inlet holes and the second air inlet 110.

[0047] The first air inlet 102 is formed by using a plurality of air inlet holes, so that a large amount of external air can quickly enter the interior of the housing 100 .

[0048] The second air inlet 110 on the reactor 106 is provided on the side wall of the reactor 106 so that the air inside the housing 100 can enter the reactor 106 from the side of the reactor 106. At the same time, in order to allow the air inside the housing 100 to quickly enter the reactor 106, a fan 124 is further provided between the first air inlet 102 and the second air inlet 110. The air inside the housing 100 can be quickly blown into the reactor 106 by the acceleration of the fan 124.

[0049] See also Figure 3 According to one embodiment of the present invention, sealing silicone grease 126 is coated between the first air outlet 104 and the second air outlet 112; a sealing structure is formed between the first air outlet 104 and the second air outlet 112, and the sealing structure includes a boss and a groove that cooperate with each other, the boss is formed in one of the first air outlet 104 and the second air outlet 112, and the groove is formed in the other of the first air outlet 104 and the second air outlet 112, and the sealing silicone grease 126 is formed between the boss and the groove.

[0050] By applying sealing silicone grease 126 between the first air outlet 104 and the second air outlet 112, the seal between the first air outlet 104 and the second air outlet 112 can be effectively ensured. In the embodiment of the present invention, in order to improve the sealing performance between the first air outlet 104 and the second air outlet 112, a sealing structure is further provided between the first air outlet 104 and the second air outlet 112.

[0051] The sealing structure comprises a mating boss and groove. For example, the boss is located at the first air outlet 104, and the groove is located at the second air outlet 112. The boss on the first air outlet 104 and the groove on the second air outlet 112 form a non-contact inlaid structure. Sealing silicone grease 126 is applied between the boss and the groove. This seals the housing 100 and the reactor 106, and acts as a damper to stabilize the rotational speed of the reactor 106.

[0052] According to one embodiment of the present invention, a light source board 128 is installed in the installation space, the projection of the reactor 106 in the horizontal plane is located in the projection of the light source board 128 in the horizontal plane, and the light source array is formed on the light source board 128 .

[0053] By arranging the projection of the reactor 106 in the horizontal plane to be located within the projection of the light source plate 128 in the horizontal plane, it is ensured that the light source plate 128 can illuminate all the catalyst layers 108 in the reactor 106. For example, the light source plate 128 can be laid on the bottom plate of the housing 100.

[0054] According to one embodiment of the present invention, a quartz glass plate 130 corresponding to the light source array is disposed at the bottom of the reactor 106 .

[0055] like Figure 3 As shown, light emitted by the light source array above the bottom plate of the housing 100 passes through the quartz glass plate 130 and irradiates the catalyst layer 108 on the inner wall of the spiral air duct 114 of the reactor 106. The surface of the catalyst layer 108 is excited to produce electron-hole pairs, which immediately generate hydroxyl free radicals, a strong oxidant, on its surface when they come into contact with water molecules in the flowing air. As long as the light source is not interrupted and there is flowing air, hydroxyl free radicals will adhere to its surface and continuously produce oxidative decomposition effects on harmful gases in the air, generating harmless water and carbon dioxide after the reaction.

[0056] The above one or more technical solutions in the present invention have at least one of the following technical effects:

[0057] The rotor type air purifier provided in the embodiment of the present invention is provided with an installation space in the housing 100, a rotatable reactor 106 is provided in the installation space, and a second air inlet 110 and a second air outlet 112 are provided on the reactor 106, so that after the external air flows into the reactor 106, the circulation time in the reactor 106 becomes longer accordingly. Moreover, under the action of the flowing air, the reactor 106 rotates with the flow of the air, so that the relative flow time of the air flow in the reactor 106 is longer, the reaction is more complete, and there is no need to provide an additional driving device. By arranging a catalyst layer 108 inside the reactor 106 and arranging a light source array at a position corresponding to the reactor 106 in the housing 100, the harmful chemical gaseous pollutants in the air can be decomposed by the reaction of the light source array and the catalyst layer 108, and harmless water and carbon dioxide are generated after the reaction, thereby achieving purification of the air. At the same time, since the circulation time of the air in the reactor 106 becomes longer, the rotor type air purifier can purify a large amount of air.
