为详细说明本实用新型的技术内容、构造特征、所实现目的及效果， 以下结合实施方式并配合附图详予说明。  The detailed description of the technical contents, structural features, and the objects and effects of the present invention will be described in detail below with reference to the embodiments.

请参阅图 1 , 本实施方式中， 空气过滤装置包括环形柱状的过滤器 10和位于所述过滤器 10内中心线上的光源 20; 过滤器 10包括活性炭 层 11和位于活性炭层 11外侧的滤纸层 12 , 所述活性炭层 1 1中装载有 活性炭， 所述活性炭表面涂覆有光触媒； 活性炭层 11面向所述光源 20。 由于活性炭一般为颗粒形状， 为使活性炭能相对均勾地分布于活性炭层 中， 活性炭层 1 1 包括框架和筛网， 框架为网格状并由筛网覆盖形成装 载活性炭的空间， 在使用时， 空气从筛网进入网格中被活性炭过滤。  Referring to FIG. 1 , in the present embodiment, the air filtering device includes a ring-shaped column filter 10 and a light source 20 located on a center line of the filter 10 ; the filter 10 includes an activated carbon layer 11 and a filter paper located outside the activated carbon layer 11 . In the layer 12, the activated carbon layer 11 is loaded with activated carbon, the surface of the activated carbon is coated with a photocatalyst; and the activated carbon layer 11 faces the light source 20. Since the activated carbon is generally in the shape of a particle, in order to allow the activated carbon to be relatively uniformly distributed in the activated carbon layer, the activated carbon layer 1 1 comprises a frame and a mesh, and the frame is in the form of a grid and is covered by the screen to form a space for loading the activated carbon. The air enters the grid from the screen and is filtered by activated carbon.

本实用新型的空气过滤装置， 在空气经过过滤器时， 部分空气污染 物会被活性炭吸附或被滤纸过滤， 从而起到净化空气的作用， 当光源点 亮时， 光照在光触媒表面， 光触媒会产生化学反应， 产生强烈催化降解 功能， 能有效地降解空气中有毒有害气体， 杀灭多种细菌， 并能将细菌 或真菌释放出的毒素分解及无害化处理， 同时还可除臭抗污。 由于增加 了光触媒及相应的光源， 大大提高该空气过滤装置的空气净化效果。 The air filtering device of the utility model partially partially pollutes air when passing through the filter The object will be adsorbed by activated carbon or filtered by filter paper to purify the air. When the light source is lit, the light will be on the surface of the photocatalyst. The photocatalyst will produce a chemical reaction, which will produce a strong catalytic degradation function, which can effectively degrade the toxic and harmful gases in the air. It kills a variety of bacteria and can decompose and harm the toxins released by bacteria or fungi, and also deodorize and stain. The air purification effect of the air filter device is greatly improved by the addition of the photocatalyst and the corresponding light source.

由于过滤器 10为环形， 而光源 20设置于中心线上， 光线比较均匀 于照射于活性炭层 1 1 , 使各处的光触媒均能受到激发。  Since the filter 10 is annular and the light source 20 is disposed on the center line, the light is relatively uniform to be irradiated onto the activated carbon layer 1 1 so that the photocatalysts everywhere can be excited.

本实施例中， 光源 20为 LED光源， 具体包括底座（图中未示出）、 以过滤器 10 中心线为中心环形阵列均匀排布于灯座上的三块 LED灯板 21以及罩设所述三块 LED灯板 21的透明灯罩 22 , LED灯板 21的发光面 面向所述活性炭层 11。 其中， LED灯板 21上为条状， LED灯板 21的长 度与所述过滤器 10的高度相当， LED灯板 21上沿长度方向设置有多颗 LED灯珠。 由于 LED灯发出的光线集中在 120度以内， 本实施例中， 通 过 3块 LED灯板环形阵列排布， 可以达到光线角度 360度照射， 更好地 激发光触媒。  In this embodiment, the light source 20 is an LED light source, and specifically includes a base (not shown), three LED light panels 21 uniformly arranged on the socket with the annular array centered on the center line of the filter 10, and a cover. The transparent cover 22 of the three LED panels 21 and the light-emitting surface of the LED panel 21 face the activated carbon layer 11. The LED light board 21 has a strip shape, and the length of the LED light board 21 is equivalent to the height of the filter 10. The LED light board 21 is provided with a plurality of LED lamp beads along the length direction. Since the light emitted by the LED lamp is concentrated within 120 degrees, in this embodiment, by arranging the annular array of three LED light panels, the light angle can be 360 degrees to better excite the photocatalyst.

在劣化结构中， 过滤器 1 0 也可以截面为如矩形、 正方形等其他形 状的中空柱状， 由于光触媒加光源的作用同样也可以提高空气净化效 能， 但光触媒所接收的光的强度会不够均匀。  In the degraded structure, the filter 10 may also have a hollow column shape of other shapes such as a rectangle or a square. The effect of the photocatalyst plus the light source can also improve the air purification effect, but the intensity of the light received by the photocatalyst may not be uniform enough.

本实用新型还提供一种空气净化器， 包括壳体、 风机和如上文所述 的空气过滤装置， 所述壳体上设有进风口和出风口， 所述风机和空气过 滤装置固定设置于壳体内， 所述进风口至所述过滤器至所述出风口形成 空气流通通道， 所述风机设置于该空气流通通道中。 该空气净化器工作 时， 风机对空气起到抽吸作用， 使房间内空气从进气口进入壳体内， 并 进入过滤器中依次经活性炭层和滤纸层过滤后从出风口回到房间内。  The utility model also provides an air purifier, comprising a casing, a fan and an air filtering device as described above, wherein the casing is provided with an air inlet and an air outlet, and the fan and the air filtering device are fixedly arranged on the shell In the body, the air inlet to the filter to the air outlet forms an air circulation passage, and the fan is disposed in the air circulation passage. When the air purifier is working, the fan sucks the air, so that the air in the room enters the casing from the air inlet, enters the filter and is filtered through the activated carbon layer and the filter paper layer, and then returns to the room from the air outlet.

以上所述仅为本实用新型的实施例， 并非因此限制本实用新型的专 利范围， 凡是利用本实用新型说明书及附图内容所作的等效结构或等效 流程变换， 或直接或间接运用在其他相关的技术领域， 均同理包括在本 实用新型的专利保护范围内。  The above is only the embodiment of the present invention, and thus does not limit the scope of the patent of the present invention. Any equivalent structure or equivalent process transformation made by using the specification and the drawings of the present invention may be directly or indirectly applied to other The related technical fields are all included in the scope of patent protection of the present invention.
