As shown in fig. 1 and 2, an air cleaning device 100 according to an embodiment of the present invention includes a housing 10, a water purification member 20, and a photocatalyst layer.
Specifically, the housing 10 has an air inlet 11 and an air outlet 12, a rotary chamber 10a communicating the air inlet 11 and the air outlet 12 is defined in the housing 10, and a water storage chamber 10b is defined at the bottom of the rotary chamber 10a, wherein the rotary chamber 10a refers to a space surrounded by at least the side wall and the bottom wall of the housing 10, and as shown in fig. 2, the rotary chamber 10a includes a space where the water purification member 20 is located and the water storage chamber 10 b. The outside air can enter the housing 10 from the air inlet 11, pass through the rotating chamber 10a and be discharged from the air outlet 12 after being purified at the purification assembly 21 of the water purification member 20.
The water purification member 20 is disposed in the rotating chamber 10a, wherein the water purification member 20 comprises a purification component 21 and a water distribution component 22, specifically, the purification component 21 is rotatably disposed in the rotating chamber 10a, the water distribution component 22 is disposed in the rotating chamber 10a and distributes water toward the purification component 21, as shown in fig. 2, the water distribution component 22 is disposed upstream of the purification component 21, and the upstream refers to an area below the purification component 21 and bounded by the purification component 21.
In some alternative embodiments of the present invention, the water outlet end of the water distribution assembly 22 extends into the purification assembly 21, and the water in the water storage chamber 10b flows upward through the water distribution assembly 22 to the upper end (i.e. the water outlet end) of the water distribution assembly 22 and is sprayed into the purification assembly 21, so as to purify the particles in the air and dissolve a part of the toxic and harmful gases.
In alternative embodiments of the present invention, the water outlet end of the water distribution assembly 22 is spaced apart from the purification assembly 21 in the axial direction, and the water in the water storage chamber 10b flows upward through the water distribution assembly 22 to the upper end (i.e. the water outlet end) of the water distribution assembly 22, and is directly sprayed into the area below the purification assembly 21 of the rotating chamber 10a through the water outlet end of the water distribution assembly 22, which can also play a role of purifying air.
Besides, the photocatalyst layer is provided on the inner wall of the rotating chamber 10a and/or the surface of the water purification member 20, that is, the photocatalyst layer may be provided on the inner wall of the rotating chamber 10a, or may be provided on the surface of the water purification member 20 (including the surface of the purification module 21 and the surface of the water distribution module 22), or may be provided on both the inner wall of the rotating chamber 10a and the surface of the water purification member 20. The photocatalyst layer can catalyze and degrade toxic and harmful gases in the air after being irradiated by light, can effectively kill various bacteria in the air, and can decompose and harmlessly treat toxins released by the bacteria or fungi, namely the photocatalyst layer has the functions of removing formaldehyde in the air, sterilizing and the like under the irradiation of the light.
Optionally, a photocatalyst layer may be disposed on the inner wall of the rotary cavity 10a, specifically, the photocatalyst layer may be disposed on the entire inner wall of the rotary cavity 10a, or may be disposed on a partial area of the inner wall of the rotary cavity 10a, and under irradiation of light, the photocatalyst layer may play a role in degrading toxic and harmful gases in air and removing bacteria.
Optionally, a photocatalyst layer may be further disposed on the surface of the water distribution assembly 22, specifically, the photocatalyst layer may be disposed on the entire outer sidewall of the water distribution assembly 22, or may be disposed on a partial region of the outer sidewall of the water distribution assembly 22, and similarly, the photocatalyst layer on the water distribution assembly 22 is illuminated, so that toxic and harmful gases in the air can be purified.
Preferably, the photocatalyst layer is disposed on the surface of the purification assembly 21, and when the purification assembly 21 rotates at a high speed in the rotation chamber 10a, the photocatalyst layer can effectively contact with the gas pollution molecules contained in the air flow, bacteria, fungi, viruses and the like, and under the irradiation of light, the photocatalyst layer can degrade toxic and harmful gases in the air and sterilize the air. To further improve the air purifying effect, a photocatalyst layer may be simultaneously provided on the surface of the purifying assembly 21, the surface of the water distributing assembly 22 and the inner wall of the rotating chamber 10 a.
According to the air purification device 100 of the embodiment of the invention, the photocatalyst layer is arranged on the inner wall of the rotary cavity 10a and/or the surface of the water purification member 20, and the light irradiates on the inner wall of the rotary cavity 10a and/or the surface of the water purification member 20, so that not only can particulate matters in the air be removed, but also toxic and harmful gases such as formaldehyde in the air can be decomposed, and meanwhile, the functions of deodorization, sterilization and the like are also provided, and the air purification effect is obviously improved.
Alternatively, the air inlet 11 may include a single air inlet, or may include a plurality of air inlets 11 arranged at intervals on a wall surface of the casing, or the air inlets 11 are in a mesh structure, and different structures of the air inlets 11 are applied to different practical situations, which is not specifically limited in the present invention.
As shown in fig. 2 and 4, according to an embodiment of the present invention, the air purification apparatus 100 further includes a germicidal lamp 30, the germicidal lamp 30 is disposed in the rotary chamber 10a, for example, the germicidal lamp 30 can be an ultraviolet lamp, so that by providing a lamp illumination condition in the rotary chamber 10a, the illumination on the inner wall of the rotary chamber 10a and on the surface of the water purification member 20 is more sufficient, and the illumination range is expanded, thereby making the photocatalyst layer work more efficiently, degrading toxic and harmful gases in the air more effectively, removing germs in the air, and in addition, the ultraviolet lamp itself has a germicidal effect, further enhancing the air purification effect.
As shown in fig. 4, according to an alternative example of the present invention, the germicidal lamp 30 is disposed between the purification component 21 and the water distribution component 22, so that the light emitted from the germicidal lamp 30 can irradiate both the surface of the purification component 21 and the water distribution component 22, and can also irradiate the inner wall of the rotary cavity 10a, and if the photocatalyst layers are disposed on the surface of the purification component 21, the surface of the water distribution component 22, and the inner wall of the rotary cavity 10a, the light of the germicidal lamp 30 can irradiate the photocatalyst layers, so that the photocatalyst layers on the surfaces all function, thereby not only expanding the range of degrading toxic and harmful gases in the air, but also enhancing the air disinfection effect, and significantly improving the air purification effect.
Alternatively, the germicidal lamp 30 may be disposed above the cleaning assembly 21, and the light from the germicidal lamp 30 may effectively irradiate the photocatalyst layer on the upper surface of the cleaning assembly 21, and also effectively irradiate the photocatalyst layer on the inner wall of the rotary chamber 10a above the cleaning assembly 21, so as to degrade the toxic and harmful gases (such as formaldehyde, etc.) in the air and remove the germs in the air.
It should be noted that, as shown in fig. 2, the germicidal lamp 30 may include a plurality of germicidal lamps 30, for example, two, three, etc., and the plurality of germicidal lamps 30 may be all located below the purification assembly 21, may be all located above the purification assembly 21, or the plurality of germicidal lamps 30 may be respectively located at upper and lower sides of the purification assembly 21, and for the multi-stage purification assembly 21, the germicidal lamps 30 may also be located between the multi-stage purification assemblies 21.
According to another embodiment of the present invention, the portion of the sidewall of the housing 10 that is at the same axial height as the purifying assembly 21 is configured as a transparent portion, so that the external visible light can irradiate the photocatalyst layer on the surface of the purifying assembly 21 through the transparent portion, and can also irradiate the photocatalyst layer on the partial inner wall of the rotating cavity 10a, thereby purifying the harmful gas such as formaldehyde in the air, and by arranging the transparent portion on the sidewall of the housing 10, the external light source of the visible light can be utilized, thereby saving the cost, reasonably utilizing the energy, and simplifying the structure of the air purifying apparatus 100.
Alternatively, the transparent part may be disposed in other regions of the sidewall of the casing 10, for example, a portion of the sidewall of the casing 10 having the same axial height as the water distribution assembly 22, a portion of the sidewall of the casing 10 having a height higher than the purification assembly 21, and a portion of the sidewall of the casing 10 having the same axial height as the water storage chamber 10b, as long as the photocatalyst layer on the surface of the water purification member 20 and the photocatalyst layer on the inner wall of the rotating chamber 10a can be irradiated with visible light, which is not particularly limited by the present invention.
It can be understood that the housing 10 can be configured as a transparent housing 10, so that visible light can penetrate through the transparent housing 10 from all directions and irradiate into the rotating cavity 10a, the range of irradiating the photocatalyst layer by the visible light is enlarged, the air purifying effect is enhanced, and an irradiation device does not need to be specially arranged in the rotating cavity 10a, so that the cost is saved, and the structure is simplified.
According to an alternative example of the present invention, the transparent portion is formed as an annular transparent area, so that visible light can be irradiated from the periphery of the rotating chamber 10a, so that the photocatalyst layer on the peripheral surface of the purification assembly 21 can be uniformly irradiated by the visible light, thereby making the air purification in the rotating chamber 10a more uniform.
According to an alternative example of the present invention, the sterilizing lamp 30 may be disposed in the rotating chamber 10a on the basis of the transparent portion disposed on the housing 10, so as to further enhance the effect of light irradiation, and fully perform the degradation and sterilization functions of the photocatalyst layer in the air purifying device 100, and further, since the sterilizing lamp 30 itself has a sterilization function, bacteria, viruses, etc. in the air may be removed, thereby further enhancing the effect of air purification.
As shown in fig. 4, according to an alternative embodiment of the present invention, the purification assembly 21 includes a rotating disk 211, the rotating disk 211 is provided with a first mesh, the water distribution assembly 22 is disposed below the rotating disk 211, water enters the water distribution assembly 22 and flows from bottom to top, the water is sprayed to the periphery through the upper end of the water distribution assembly 22 to form fine droplets, the fine droplets are distributed in the space below the rotating disk 211, the fine droplets meet the air flow in the rotating chamber 10a, for example, by providing an atomizing device at the upper end of the water distribution assembly 22, the water is atomized by the atomizing device and then mixed with the air in the rotating chamber 10a, the fine droplets capture particles and part of harmful gas in the air flow, meanwhile, the air flow flowing upwards entrains part of the water, and the rotating disk 211 rotating at high speed intercepts the droplets in the air flow and throws them onto the inner wall of the rotating chamber 10 a.
By arranging the photocatalyst layer on the surface of the rotating disk 211, the surface (photocatalyst layer) of the rotating disk 211 is efficiently contacted with harmful gases (such as formaldehyde and the like) and germs in the air flow under the condition that the rotating disk 211 rotates at a high speed, and after being irradiated by the germicidal lamp 30 or visible light, the photocatalyst layer can play a role in degrading toxic and harmful gases and sterilizing, so that the air purification effect is further improved.
Optionally, a photocatalyst layer is disposed on the lower surface or the whole surface of the rotating disk 211, as shown in fig. 4, for example, the germicidal lamp 30 is disposed between the rotating disk 211 and the water distribution assembly 22, so that the light emitted from the germicidal lamp 30 can be irradiated on the lower surface of the rotating disk 211, and also can be irradiated on the peripheral inner walls of the rotating cavity 10a and the surface of the water distribution assembly 22, thereby expanding the range of degrading toxic and harmful gases in the air and enhancing the disinfection effect on the air. Preferably, as shown in fig. 4, for example, the germicidal lamp 30 is disposed right above the water distribution assembly 22, and the germicidal lamp 30 is also disposed right below the rotating disk 211, so that the light intensity of the light emitted by the germicidal lamp 30 irradiating on the inner wall of the rotating cavity 10a is substantially the same, and similarly, the light intensity of the light irradiating on the rotating disk 211 is also substantially the same in the circumferential direction, so that the degradation effect of the photocatalyst layer on the toxic and harmful gases in the air in the circumferential direction of the rotating cavity 10a is substantially the same, and the air purification in the rotating cavity 10a can be more uniform.
According to an alternative embodiment of the present invention, the purification assembly 21 comprises a rotating packed bed, the rotating packed bed is a loose medium, the water distribution assembly 22 distributes water towards the inside of the rotating packed bed, the liquid is shredded into a liquid film and fine liquid droplets due to the high-speed rotation of the rotating packed bed, the liquid droplets capture the impurity particles and part of the polluted gas in the gas flow, and the liquid droplets containing dust are thrown by the rotating packed bed onto the inner wall of the rotating chamber 10a under the action of centrifugal force.
