Furthermore, the inner wall of the tube body 2.1 is provided with a groove to form a cavity, an ultraviolet lamp is arranged in the cavity and used for irradiating the filter cloth 2.22, and the ultraviolet lamp has the advantages that the ultraviolet lamp can kill viruses and bacteria filtered on the filter cloth 2.22 by irradiating the filter cloth 2.22 instead of directly sterilizing air due to long sterilization time, generally from half an hour to an hour, so that the replacement time of the filter cloth 2.22 is prolonged, and the filter cloth is replaced once in a week or even a longer time, and the workload of replacement is greatly reduced.
In another embodiment of the present invention, a groove 2.32.3 is disposed on a bottom surface of an inner wall of the tube 2.1 near an air inlet surface of the filter cloth 2.22, a return pipe 2.4 is disposed at a bottom of the groove 2.32.3, and another end of the return pipe 2.4 is connected to a bottom of the humidification mechanism 1, such as a humidification bottle, which has an effect that a part of water molecules will condense on the filter cloth 2.22, and these condensed water drops flow into the groove 2.32.3 at the bottom along the filter cloth 2.22 and finally flow back to the humidification bottle through the return pipe 2.4, thereby recovering the condensed water and preventing the condensed water from accumulating in the tube 2.1.
Still further, a blocking part 2.5 is arranged on the bottom surface of the inner wall of the tube body 2.1, which is away from the air inlet surface (i.e. located on the air outlet surface) of the filter cloth 2.22, and the blocking part 2.5 is a protrusion, so that the blocking part prevents water molecules which may possibly condense on the air outlet surface of the filter cloth 2.22 from condensing and flowing to a using unit, and ensures that all condensed water flows to the humidifying bottle.
In another embodiment of the present invention, the present invention further includes a pressing mechanism 4, which is used to press the toxin filtering component 2.2 into the slot on the tube body 2.1, the pressing mechanism 4 ensures the connection pressure between the toxin filtering component 2.2 and the tube body 2.1, and ensures that the connection pressure does not loosen automatically and the sealing effect is reduced, the pressing mechanism 4 is a mechanism capable of applying pressure, such as a screw structure, and presses the frame body 2.21 of the toxin filtering component 2.2 by the rotation of the bolt to achieve sealing. It is comparatively preferred, as shown in fig. 4, mechanism 4 of exerting pressure includes arc support body 4.1, the one end of arc support body 4.1 rotate connect in on the body 2.1, the middle part butt of arc support body 4.1 in on the toxin filtering component 2.2, the other end elastic lock joint of arc support in on the protruding portion 2.11 on the body 2.1, the other end of arc support is arc lock joint portion 4.2 that has certain deformability, and its lock joint is on protruding portion 2.11 after the application of force pushes down for the arc support obtains framework 2.21 and realizes the extrusion, and then upwards pulls open the application of force when dismantling and buckle portion 4.2, takes out toxin filtering component 2.2 after the use, inserts another toxin filtering component 2.2.
