Traditional air purification devices suffer from reduced sterilization and disinfection effectiveness in high-microbial-contamination environments due to the adsorption of tiny particles by ultraviolet light tubes.
The UV lamp tube is cleaned by rotating the light tube cleaning assembly. The drive mechanism makes it slide along the length of the lamp tube to ensure smooth light transmission.
This improves the cleaning efficiency of ultraviolet lamps, reduces the risk of lamp damage, and ensures the stability of sterilization and disinfection effects.

Description
Technical Field
[0001] This utility model specifically relates to the field of air purification equipment technology, and more specifically to an air purification device with disinfection function for cleanrooms. Background Technology
[0002] Traditional air purification devices typically rely on filtration technology, such as screen filters, to remove airborne dust particles. However, with technological advancements and increasingly stringent environmental requirements, simply filtering dust is no longer sufficient. This is especially true in environments with extremely high demands for microbial contamination control, such as biological laboratories and pharmaceutical workshops, where airborne bacteria, viruses, and other microorganisms can pose a serious threat to the quality of experimental samples or pharmaceuticals.
[0003] To address this, ultraviolet (UV) lamps were installed in the purification system to sterilize the introduced gas. However, during continuous operation, tiny particles in the introduced gas gradually adhered to and covered the UV lamps, obstructing the propagation of UV light and thus reducing its sterilization effect.

[0035] With reference to the accompanying drawings of the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below.
[0036] Example: Please refer to the appendix. Figure 1-4 This utility model provides a technical solution: an air purification device with disinfection function for a cleanroom, comprising:
[0037] The purification housing 5 has a sieve plate 7 installed at both its front and rear ports, and a front baffle 1 and a rear baffle 3 are sealed and fixed inside the purification housing 5.
[0038] The exhaust fan 2 is installed inside the purification housing 5 and is located between the front baffle 1 and the rear baffle 3. The air inlet and outlet of the exhaust fan 2 are respectively connected to the air inlets installed on the front baffle 1 and the rear baffle 3.
[0039] The composite coarse filter 6 is fixed on the front end face of the front baffle 1;
[0040] The composite fine filter 4 is fixed on the rear end face of the rear baffle 3;
[0041] U-shaped partition 2 11 is fixed on the inner side wall of the purification housing 5. A lamp holder is fixed on the side wall of the U-shaped partition 2 11, and two ultraviolet light tubes 17 are installed on the lamp holder.
[0042] And a light tube cleaning assembly, which can be slidably engaged with each ultraviolet light tube 17, and the light tube cleaning assembly is driven by a drive mechanism and slides along the length of the ultraviolet light tube 17 to clean the tube wall of the ultraviolet light tube 17.
[0043] In this embodiment, the light tube cleaning assembly includes:
[0044] The outer casing 22 is cleaned, and it has two cleaning ports that extend through it.
[0045] There are two rotating rings 23, which are located in two cleaning ports respectively. Each rotating ring 23 has teeth on its outer side wall and each rotating ring 23 is fitted onto its corresponding ultraviolet tube 17.
[0046] And a pinion 20, which meshes with two rotating rings 23 for transmission, and the pinion 20 is driven by a motor 2 fixed inside the cleaning housing 22;
[0047] The inner wall of the rotating ring 23 is equipped with bristles, and both ends of the rotating ring 23 are provided with protruding rings 21, which are rotatably connected to the annular groove on the inner wall of the cleaning housing 22.
[0048] Specifically, the second motor drives the pinion 20 to rotate. Due to the meshing transmission relationship between the pinion 20 and the two rotating rings 23, the two rotating rings 23 are driven to rotate, so as to perform a rotary cleaning process on the ultraviolet lamp tube.
[0049] It should also be noted that the rotation cleaning method is relatively gentle. The cleaning tool applies more even pressure to the surface of the lamp tube during rotation, making it less likely to apply excessive force in certain areas, thus reducing the risk of damage to the lamp tube during cleaning.
[0050] In this embodiment, the brush bristles are made of polyester material;
[0051] Specifically, polyester bristles are characterized by high softness, a smooth surface, and minimal damage to object surfaces. They also have good water absorption and drainage properties, which can quickly remove dust and moisture, resulting in excellent cleaning performance.
[0052] In this embodiment, the driving mechanism includes:
[0053] The screw 15 has one end rotatably mounted on the inner wall of the purification housing 5, and the other end of the screw 15 is inserted into the U-shaped partition 11 and fixedly connected to the driven gear 14.
[0054] The sliding column 18 is installed between the U-shaped partition 11 and the inner wall of the purification housing 5;
[0055] The internal threaded ring 16 is threadedly connected to the screw 15 and is fixed to the cleaning housing 22.
[0056] The slip ring 19 is slidably engaged with the sliding column 18 and is fixed to the cleaning housing 22;
[0057] And motor 24, which is fixed on the inner wall of the purification housing 5 and located in the U-shaped partition 11. The drive end of motor 24 is fixedly installed with drive gear 13, and drive gear 13 meshes with driven gear 14 for transmission.
[0058] Specifically, the screw 15 is indirectly driven to rotate by the motor 24. Due to the threaded connection between the screw and the internal threaded ring, and the restriction of the movement direction of the slip ring and the slip column, the tube cleaning assembly can only slide along the length of the ultraviolet lamp tube to perform all-round cleaning of the tube wall of the ultraviolet lamp.
[0059] In this embodiment, a gas collecting hood 9 is also provided at the front port of the purification housing 5, and the gas collecting hood 9 is located behind the sieve plate 7 inside the front port of the purification housing 5.
[0060] In this embodiment, a U-shaped partition 10 is fixed on the inner wall of the purification housing 5 and in front of the U-shaped partition 2 11. A motor 3 is fixed on the inner wall of the purification housing 5 inside the U-shaped partition 10.
[0061] A sealing seat 12 driven by a motor is rotatably installed between the U-shaped partition 10 and the inner wall of the purification housing 5. The sealing seat 12 has a fan-shaped cross section and can cooperate with the air exchange port 8 of the air collection hood 9 to seal it.
[0062] In other words, the shape of the sealing seat 12 matches the shape of the air exchange port, and the sealing seat 12 controls the sealing state of the air exchange port by rotating.
[0063] In this embodiment, the heights of U-shaped partition 10 and U-shaped partition 21 are the same as the depth of the inner cavity of the purification housing 5, so that the space between the U-shaped partition 10 and U-shaped partition 21 and the inner wall of the purification housing is sealed.
[0064] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
