DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: a gas filtering device for ventilation of a square cabin hospital, comprising:

[0030] A ventilation duct 1 and an ultraviolet lamp body 4 fixed therein, the ultraviolet lamp body 4 is designed with an arc-shaped translucent lampshade 5; the two ends of the ventilation duct 1 are respectively connected to the external fresh air environment and the target cabin; a quartz glass tube 6 is rotated and attached to the outer wall of the translucent lampshade 5, and the quartz glass tube 6 does not interfere with the normal operation of the ultraviolet lamp body 4; a driver for controlling the rotation of the quartz glass tube 6 is installed on the ventilation duct 1, and when the quartz glass tube 6 rotates, the dirty area can be transferred, and the clean area can be quickly covered on the outer wall of the translucent lampshade 5; an arc-shaped cover body 3 is installed on the outer wall of the ventilation duct 1, and a cleaning component for cleaning the dirty area of ​​the quartz glass tube 6 is installed on the arc-shaped cover body 3.

[0031] In the prior art, the lamp tube of the ultraviolet lamp needs to be in direct contact with the incoming or outgoing air, and the lamp tube is exposed to the air. During the continuous ventilation or exhaust process, dust, water mist, water marks or organic matter in the air cause the outer wall of the lamp tube to become dirty. The dirty lamp tube will affect the irradiation intensity of the ultraviolet light, resulting in a reduced sterilization effect. The lamp tube should be properly cleaned, but currently the lamp tube needs to be shut down for cleaning, and it takes a long time to clean the lamp tube. In the present invention, through the cooperation between the arc-shaped cover body 3, the translucent lampshade 5 and the quartz glass tube 6, the quartz glass tube 6 can be coated on the outer wall of the translucent lampshade 5, and can also be rotatably assembled on the outer wall of the translucent lampshade 5. Since the quartz glass tube 6 is coated or attached to the outer wall of the translucent lampshade 5, the translucent lampshade 5 is no longer directly exposed to the air. As a substitute for the light-transmitting lampshade 5, the quartz glass tube 6 can receive dirt from the air for the light-transmitting lampshade 5. The light-transmitting lampshade 5 is integrated with the ultraviolet lamp body 4. It is troublesome to clean the light-transmitting lampshade 5. By rotating the quartz glass tube 6, the clean area on the quartz glass tube 6 can be transferred to the outside of the light-transmitting lampshade 5, so that the light-transmitting lampshade 5 can work directly, and the dirty area will be processed by the clean component, thus serving as a spare clean area. Therefore, the present invention can use the quartz glass tube 6 to shield the outer wall of the light-transmitting lampshade 5 from dirt, and can quickly switch between the dirty area and the clean area, so that the light-transmitting lampshade 5 can be used uninterruptedly, thereby improving the sterilization quality of the air. Due to its material properties, the quartz glass tube 6 will not interfere with the normal operation of the ultraviolet light, and it has good scratch resistance.

[0032] In particular, for the relatively large air flow in the square cabin hospital, circulating air ultraviolet light sterilization is usually adopted. The air will not stay statically in the ventilation duct 1, but will be circulated for sterilization, resulting in more frequent contact between the air and the lamp tube. Therefore, the quartz glass tube 6 is more needed for pollution protection, eliminating the cleaning time of the light-transmitting lampshade 5, improving the process, and allowing the light-transmitting lampshade 5 to be used for a long time without downtime.

[0033] In a preferred embodiment, the cleaning assembly includes an assembly groove 8 provided on the arc-shaped cover body 3, the quartz glass tube 6 is rotatably installed in the assembly groove 8, two extrusion cavities are provided at the lowest part of the assembly groove 8, the interior of the extrusion cavities are filled with compressed clean cotton 9, the clean cotton 9 is attached to the front and back sides of the quartz glass tube 6, and an injection hole connected to the extrusion cavity is provided on the outer wall of the arc-shaped cover body 3, please refer to Figures 3 to 6 In this embodiment, the rotation of the quartz glass tube 6 can transfer the dirty area thereon to the inside of the assembly groove 8. Cleaning liquid is adsorbed on the cleaning cotton 9, and the cleaning liquid can be injected into the extrusion cavity through the injection hole. The compressed cleaning cotton 9 can provide greater pressure friction to the outer wall of the quartz glass tube 6, thereby improving the cleaning quality of the dirty area of ​​the quartz glass tube 6.

[0034] On the basis of the embodiment of the clean component, the assembly groove 8 is opened at the end of the arc-shaped cover body 3, one end of the quartz glass tube 6 is inserted into the assembly groove 8, and the other end of the quartz glass tube 6 is fixedly installed with the assembly end 7, and the driver includes a gear ring 13 rotatably installed on the ventilation duct 1, and the annular outer wall of the assembly end 7 is fixedly installed with a gear 12, and the gear 12 is meshed and connected with the gear ring 13, please refer to Figure 6 In this embodiment, by designing the assembly end 7, the assembly end 7 can block the open end of the assembly groove 8, and the assembly end 7 can serve as an extension end of the quartz glass tube 6. The quartz glass tube 6 is designed to be thinner in terms of process, and the assembly end 7 can drive the quartz glass tube 6 to rotate, thereby completing the switching between the dirty area and the clean area, ensuring the normal use of the ultraviolet lamp body 4 and the translucent lampshade 5. Secondly, by integrating servo motors and other equipment externally, the gear ring 13 can drive the gear 12 to rotate, thereby completing the switching, and the switching process is electrified.

[0035] Based on the embodiment of the cleaning component, part of the outer wall of the arc-shaped cover body 3 is exposed outside the ventilation duct 1, and the inner wall of the assembly groove 8 outside the ventilation duct 1 is provided with a scraping angle design 15, which can pressure-scrape the outer surface of the quartz glass tube 6, see Figure 4 In this embodiment, the purpose of designing the scraping angle design 15 is to scrape the dirt on the surface of the quartz glass tube 6 before cleaning, thereby reducing interference with the use of the cleaning liquid. The cleaning liquid can be anhydrous ethanol to avoid other interferences from sticking to the cleaning cotton 9 and affecting subsequent cleaning.

[0036] Based on the embodiment of the clean component, the arc-shaped cover body 3, the assembly groove 8 and the light-transmitting lampshade 5 are all concentrically designed, and the radiation angle formed by the light-transmitting lampshade 5 is less than one hundred and eighty degrees.

[0037] Furthermore, the air inlet and outlet ends of the ventilation duct 1 are tangent to the arc-shaped outer portion of the translucent lampshade 5, and the angle formed between the air inlet and outlet ends of the ventilation duct 1 is greater than or equal to ninety degrees, which can optimize the circulation of fresh air or exhaust air and improve the quality of air irradiation.

[0038] Furthermore, an air filter module 11 is installed at the air inlet end of the ventilation duct 1. The air filter module 11 includes a photocatalyst filter and an activated carbon filter. The photocatalyst filter can be activated by ultraviolet light or other light sources to degrade toxic and harmful gases in the air, such as formaldehyde, carbon monoxide, nitrogen oxides, etc. The photocatalyst can also produce strong oxidizing substances under light, which can effectively catalyze the decomposition of harmful organic and inorganic substances, and can also eliminate bacteria and viruses, while the activated carbon filter can filter large particles and effectively adsorb harmful substances in the air.

[0039] Furthermore, a light slit is provided on the inner wall of the ventilation duct 1, and a light-collecting chamber 14 is designed on the outer wall of the ventilation duct 1. The light-collecting chamber 14 is connected to the interior of the ventilation duct 1 through the light slit, and the light slit is located on the radial line of the light-transmitting lampshade 5. A probe of an ultraviolet radiation meter is installed inside the light-collecting chamber 14, and the probe is used to detect the intensity of the ultraviolet light. The probe can be used to determine the intensity of the ultraviolet light. If the intensity is reduced, and there is no interference from other factors, it can be determined that the quartz glass tube 6 is dirty, affecting the optimal output of the ultraviolet light. At this time, the quartz glass tube 6 can be driven to rotate so that the ultraviolet light can be optimally output.

[0040] By combining the above structures, the quartz glass tube 6 can be used to shield the outer wall of the light-transmitting lampshade 5 from dirt, and the dirty area and the clean area can be quickly switched, so that the light-transmitting lampshade 5 can be used uninterruptedly, thereby improving the sterilization quality of the air.

[0041] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
