[0002] Indoor air pollutants mainly include three types of pollutants: gaseous pollutants such as volatile organic compounds, microbial pollutants, and solid particle pollutants. The photocatalytic air purification device has triple sterilization functions such as photocatalytic sterilization, ultraviolet sterilization, and dust removal system sterilization. It uses the mechanism of nano-photocatalysis and a carrier with a large specific surface area and high adsorption performance to load nano-titanium dioxide to prepare a photocatalytic network, which can exert the synergistic effect of efficient physical adsorption and photocatalytic decomposition, achieve lasting decomposition of organic pollutants such as formaldehyde and benzene, and timely kill pathogens, and decompose organic pollutants into carbon dioxide and water, eliminating the defects of physical adsorption saturation and secondary pollution.
[0003] Existing photocatalytic air purification devices generally use ultraviolet lamps and fans to make air containing harmful gases pass through catalysts at a specific speed.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0032] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0033] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] Existing photocatalytic air purification devices generally use the ultraviolet irradiation lamp on the lamp board 15 and the fan 14 to make the air containing harmful gases pass through the catalyst at a specific speed. The catalyst on the catalyst plate 12 reacts chemically with the harmful gases under the irradiation of ultraviolet light to achieve the purpose of purification.
[0035] In the related art, since long-term use of ultraviolet light will greatly reduce its service life, the service life of the ultraviolet light is extended by using sunlight and ultraviolet light together. However, the angle of sunlight is not fixed, and the angle of the catalytic plate 12 cannot be adjusted, so the catalyst on the catalytic plate 12 cannot be better catalyzed by sunlight, and the catalytic plate 12 is not easy to disassemble, and the maintenance involved in the later stage is more troublesome, and its use has certain limitations.
[0036] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a photocatalytic air purification device. When the angle of sunlight changes, the catalytic plate 12 can be driven by the motor 22 to rotate and adjust the angle of the catalytic plate 12 so that the sunlight can be better irradiated on the catalytic plate 12 for catalysis. When maintenance is involved later, the output end of the motor 22 and the slider 26 can be separated from the catalytic plate 12 to complete disassembly by rotating the bolt 27.
[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0038] Combination Figure 1-Figure 5 The embodiment of the present application provides a photocatalytic air purification device, including a main body component 1; the main body component 1 includes: a shell 11 with a catalytic plate 12 arranged inside it; a light-transmitting cover 13 arranged on the shell 11; a fan 14 arranged in the shell 11; a light board 15 arranged on the shell 11; an adjustment component 2 is arranged on the shell 11, and the adjustment component 2 includes: a slot body 21 opened in the shell 11; a slide plate 28 arranged in the slot body 21; a motor 22 arranged on the slide plate 28; a limit groove 23 opened on the output end of the motor 22; a slot body 24 opened on one side of the catalytic plate 12; a slot body 3 25 opened in the shell 11; a slider 26 slidably installed in the slot body 3 25, and one end of the slider 26 is embedded in the catalytic plate 12; a bolt 27 is rotatably connected to the outer sides of the slider 26 and the slide plate 28, respectively, and both are threadedly connected to the shell 11.
[0039] When in use, the fan 14 is started to allow air to enter the inner cavity from the air inlet on the shell 11. At this time, sunlight passes through the light-transmitting cover 13 and shines on the catalytic plate 12. The air containing harmful gases passes through the catalyst on the catalytic plate 12 at a specific speed, causing a chemical reaction to purify it. The purified air is blown out from the air outlet on the light-transmitting cover 13. When it is observed that the angle deviation of sunlight shining on the catalytic plate is large and the catalytic plate 12 needs to be adjusted, the motor 22 is started. Since there is a protruding structure in the groove body 24 and it is embedded in the limiting groove 23, the output end of the motor 22 is embedded in the limiting groove 23 through the protruding structure, and the catalytic plate 12 is driven to rotate. The catalytic plate 12 is rotatably connected to the slider 1 26 to adjust the angle of the catalytic plate 12 so that it can face the sunlight to improve the catalytic effect. Shell 11 is provided with a limiting protrusion, and the light-transmitting cover 13 is clamped with the shell 11 through the limiting protrusion on the shell 11. When the catalytic plate 12 is disassembled, the light-transmitting cover 13 is pulled off the shell 11, and the slide plate 28 is slidably connected in the slot body 1 21, and the motor 22 is fixedly connected to the slide plate 28. The bolt 27 is threadedly connected to the shell 11, and the bolt 27 is rotated respectively to make the slide block 1 26 move in the slot body 3 25 and the slide block 28 drive the motor 22 to move in the slot body 1 21, so that the slide block 1 26 and the output end of the motor 22 are separated from the catalytic plate 12 respectively, and then the catalytic plate 12 is pulled upward to make the catalytic plate 12 slide upward out of the shell 11, and the disassembly of the catalytic plate 12 is completed. The light board 15 can be started to replace the sunlight to complete the catalysis of the catalyst when there is no sunlight or the sunlight is not strong.
[0040] Specifically, the light-transmitting cover 13 is made of quartz glass and has good light transmittance in the entire spectrum band from ultraviolet to infrared; the catalytic plate 12 is a titanium dioxide photocatalytic plate, that is, it is coated with an oil-coated titanium dioxide layer; the lamp board 15 is an LED ultraviolet lamp board of model HS-UVB.
[0041] In some embodiments, the adjustment component 2 further includes an arc surface 241 , which is opened in the second slot body 24 ; when the catalytic plate 12 is installed, the output end of the motor 22 can more easily enter the second slot body 24 through the limiting groove 23 .
[0042] In some embodiments, the housing 11 and the light-transmitting cover 13 are provided with arc-shaped surfaces; when the catalytic plate 12 rotates, the edge of the catalytic plate 12 can always be attached to the inner wall of the housing 11 and the light-transmitting cover 13 .
[0043] Specifically, when the fan 14 delivers air, it can be ensured that the air always passes through the catalytic plate 12, so that the catalytic reaction of the incoming air is complete.
[0044] In some embodiments, the slider 1 26 is provided with an arc surface, which can make it easier to embed the slider 1 26 into the catalyst plate 12 during installation.
[0045] In some embodiments, a disassembly component 3 is provided on the light-transmitting cover 13, and the disassembly component 3 includes: a groove body 4 31 opened in the light-transmitting cover 13; a slide bar 32 is slidably installed in the groove body 4 31, and one end of the slide bar 32 is embedded in the shell 11; a ring body 34 is arranged on the outside of the slide bar 32; a spring 1 33 is arranged on the outside of the slide bar 32; the ring body 34 and the slide bar 32 are fixedly connected, and when the light-transmitting cover 13 needs to be disassembled, the slide bar 32 is pulled respectively to move the slide bar 32 in the groove body 4 31, and the spring 1 33 is compressed by the ring body 34, and the slide bar 32 is continued to be pulled until the slide bar 32 is completely separated from the shell 11. At this time, the light-transmitting cover 13 is no longer limited and can be directly removed from the top. After releasing the slide bar 32, the spring 1 33 drives the slide bar 32 to reset through the ring body 34.
[0046] In some embodiments, a filter screen 4 is disposed on one side of the fan 14 to effectively prevent dust particles and the like from entering the housing 11 and thereby clogging the catalytic plate 12 and reducing the catalytic effect.
[0047] Specifically, a filter screen 4 is also provided at the position of the air outlet on the light-transmitting cover 13 to further prevent dust particles from entering the light-transmitting cover 13 from the position of the air outlet and clogging the catalytic plate 12 .
[0048] In some embodiments, each of the filters 4 is provided with a disassembly component 2 5, and the disassembly component 2 5 includes: a groove body 51 opened on one side of the filter 4, and the light-transmitting cover 13 also has a corresponding groove; a spring 2 52 is arranged in the groove body 51; a slider 2 53 is slidably installed in the groove body 51; and a slider 3 54 is slidably installed in the groove body 51.
[0049] When the filter 4 needs to be cleaned or replaced, the slider 3 54 is pressed. Due to the action of the inclined surface, the slider 2 53 is driven to slide down in the groove body 51. At the same time, the spring 2 52 is compressed, and the slider 3 54 is continued to be pressed to make the slider 2 53 separate from the light-transmitting cover 13 or the housing 11, so that the slider 2 53 completely enters the groove body 51. At this time, the filter 4 can be cleaned or replaced as a whole. After the filter 4 is taken out, the slider 3 54 is released. The spring 2 52 is reset to drive the slider 2 53 to reset and then drive the slider 3 54 to reset. The slider 2 53 and the outer side of the slider 3 54 are limited and will not fall off from the groove body 51.
[0050] In some embodiments, a pull ring 6 is provided on one side of the filter screen 4 , so that the filter screen 4 can be removed more easily when being disassembled.
