[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] See attached document Figure 1The surgical smoke purifier with filter disinfection function in this embodiment 1 includes a housing 1. An air inlet 2 and an air outlet 3 are respectively located at the top and bottom of the housing 1. A control panel 41 is provided on the surface of the housing 1. Air quality sensors 42 are provided on both the air inlet 2 and the air outlet 3. An air flow channel 4 connecting the air inlet 2 and the air outlet 3 is provided inside the housing 1. A primary filter 5 and a high-grade filter 6 are arranged sequentially from top to bottom in the air flow channel 4. A fan 7 is installed downstream of the high-grade filter 6 in the air flow channel 4. The air quality sensors and the fan 7 are electrically connected to the control panel 41. The primary filter 5 is a rotating belt structure. A washing chamber 8 and a dust removal chamber 9 are respectively provided on the left and right side walls of the housing 1. An active roller 10 is rotatably mounted on the top of the dust removal chamber 9. One end of the active roller 10 is connected to a dust removal motor 11. A brush roller 12 is rotatably mounted below the active roller 10. A speed reduction belt is provided between one end of the brush roller 12 and the other end of the active roller 10. The transmission mechanism 13 has several brush wheels 14 fixed on the brush roller 12 for cleaning the outer surface of the primary filter screen 5. A detachable dust collection box 15 is provided at the bottom of the dust removal chamber 9. An ultrasonic water tank 16 is provided at the bottom of the washing chamber 8. An electric water inlet valve 17 and an electric drain valve 18 are provided on the side wall of the ultrasonic water tank 16. A driven roller 19 is rotatably mounted inside the ultrasonic water tank 16, and two guide rollers 20 are rotatably mounted above the driven roller 19. The primary filter screen 5 is wound and fixedly mounted on the driving roller. 10. The driven roller 19 and two guide rollers 20 are horizontally arranged on the air flow channel 4. An ozone ultraviolet lamp 21 and a plasma generator 22 are also fixedly installed on the inner side of the primary filter 5. An ozone-free ultraviolet lamp 23 is installed below the advanced filter 6. A light guide plate 24 is provided on the inner walls of both sides of the air flow channel 4. The upper end of the light guide plate 24 extends between the primary filter 5 and the advanced filter 6, and the lower end of the light guide plate 24 extends onto the ozone-free ultraviolet lamp 23.

[0018] Working Principle: After the control panel 41 starts the fan 7, indoor air is drawn in through the air inlet 2 and sequentially filtered through the primary filter 5 and the advanced filter 6 on the air flow channel 4. Finally, it is discharged back into the indoor air environment through the air outlet 3, achieving the purification of smoke particles, dust, bacteria, viruses, and other substances in the air. The primary filter 5 is made of ordinary filter mesh layers and can only filter larger smoke particles and dust. The primary filter 5 has a two-layer structure with a rotating belt, which can improve the primary filtration effect. The advanced filter 6 is made of high-grade filter material and has a filtration efficiency of over 99.9% for particles with a diameter of 0.3μm. If a HEPA filter is used, the filtration level is higher than that of the primary filter 5, and it can further filter bacteria, viruses, formaldehyde, and other substances.

[0019] When the ozone UV lamp 21 is powered on, it can generate ozone for disinfection while simultaneously performing UV sterilization inside the primary filter 5. When O2 is irradiated with UV light of wavelength λ = 185nm, the chemical reaction process is: O2 + hr → O + O; O2 + O + M → O3 + M; hr—UV light quanta; M—any inert substance present, such as reactor walls, nitrogen, carbon dioxide gas molecules, etc. The plasma generator 22 works by boosting a low voltage to positive and negative high voltages via a step-up circuit. These high voltages ionize the air (mainly oxygen), generating a large number of positive and negative ions, and also producing trace amounts of ozone. The simultaneous neutralization of positive and negative charges by the positive and negative ions generated by the plasma generator in the air produces a huge energy release, leading to changes in the structure or energy conversion of surrounding bacteria, thus causing bacterial death and achieving sterilization. Because the number of negative ions is greater than the number of positive ions, the excess negative ions remain suspended in the air, achieving the effects of smoke elimination, dust removal, odor elimination, and improved air quality, thus promoting human health. The efficiency of ozone generation by the ozone ultraviolet lamp 21 and plasma generator 22 can be easily controlled by adjusting the power.

[0020] After the ozone-free UV lamp 23 is turned on, its ultraviolet light can be diffused through the light guide plate 24 to the upper and lower sides of the advanced filter 6. The light intensity decreases from bottom to top, expanding the sterilization space and effectively improving the disinfection effect on the air and filter element. While disinfecting the two sides of the filter element, it also gradually decomposes the ozone before and after filtration. When the ozone-free UV lamp 23 is powered on, it generates ultraviolet light with a wavelength of λ = 254nm for sterilization, which can promote the decomposition of ozone. The chemical reaction process is: O3 + hr → O2 + O; oxygen atoms O have strong oxidizing properties and can kill microorganisms. In the process of gradual decomposition of ozone, the disinfection effect of ozone can be fully utilized, making it easier to control ozone emissions to meet standards.

[0021] After a period of use, the two surfaces of the primary filter 5 will accumulate thicker and thinner layers of dust, respectively. At this point, the fan 7 can be turned off to automatically clean the primary filter 5. The dust removal motor 11 starts, driving the active roller 10, the primary filter 5, the driven roller 19, and the two guide rollers 20 to rotate. As the dust-laden surface of the primary filter 5 rotates through the dust removal chamber 9, the active roller 10 drives the brush roller 12 and brush wheel 14 to rotate via the reduction belt transmission mechanism 13. The bristles on the brush wheel 14 brush the dust off the surface of the primary filter 5 into the dust collection box 15. The dust-removed surface of the primary filter 5 can then be returned to the lower layer in the airflow channel 4 for reuse. As the primary filter 5, with its thinner dust layer, rotates through the washing chamber 8, it is immersed in the cleaning fluid within the ultrasonic water tank 16 at the driven roller 19. The ultrasonic generator and transducer at the bottom of the ultrasonic water tank 16 activate, converting the acoustic energy of the high-power ultrasonic source into mechanical vibration. This ultrasonic wave is radiated through the tank walls into the cleaning fluid. Due to the ultrasonic radiation, microbubbles in the liquid within the steel ultrasonic water tank 16 maintain vibration under the influence of the sound waves, effectively scrubbing the surface of the primary filter 5. After ultrasonic cleaning, the primary filter 5 is dehydrated and can be reused in the upper layer of the airflow channel 4. The primary filter 5 can be rotated and recycled, undergoing cleaning and dust removal in both the washing chamber and the dust removal chamber, extending its service life, reducing the need for frequent maintenance, and minimizing the risk of clogging.

[0022] Example 2: The only difference from Example 1 is that an upper sealing frame 28 and a lower sealing frame 29 for fixing the primary filter 5 are slidably installed on the airflow channel 4. A bidirectional synchronous telescopic rod 30 is fixedly installed between the upper sealing frame 28 and the lower sealing frame 29. The bidirectional synchronous telescopic rod 30 includes an electromagnet, a cylinder, two return springs, and two movable rods. The two movable rods are slidably installed at the upper and lower ends of the cylinder, respectively. An electromagnet is installed between the inner ends of the two movable rods, and a return spring is installed between the electromagnet and the movable rod. When the primary filter 5 needs cleaning, the electromagnet is energized, attracting the two movable rods to retract, driving the upper sealing frame 28 to move down and the lower sealing frame 29 to move up, respectively, releasing the fixation of the primary filter 5 and opening the slots of the primary filter 5 leading to the washing chamber 8 and the dust removal chamber 9. When the primary filter 5 is reset, the electromagnet is de-energized, and the two movable rods pop out under the action of the two reset springs, respectively driving the upper sealing frame 28 and the lower sealing frame 29 to reset, thereby fixing the primary filter 5 and sealing the slots of the primary filter 5 leading to the washing chamber 8 and the dust removal chamber 9.

[0023] Example 3: The only difference from Example 1 is that a hair dryer 31 is provided above the driven roller 19, and a ventilation opening 32 corresponding to the hair dryer 31 is provided on the side wall of the washing chamber 8. The hair dryer 31 is fixedly connected to a vertical slider 33, which is slidably connected to a vertical guide rail 34 on the inner wall of the washing chamber 8. A crank stirring rod 35 is fixedly installed at one end of the driven roller 19, and a drive connecting rod 36 is hinged between the crank stirring rod 35 and the vertical slider 33. When the driven roller 19 rotates, it drives the crank stirring rod 35. When the crank stirring rod 35 rotates, it can stir the cleaning liquid to improve the cleaning effect. On the other hand, it can drive the hair dryer 31 to move up and down through the crank rocker mechanism, avoiding the high temperature generated during the drying process that could burn out the primary filter 5.

[0024] Example 4: The only difference from Example 1 is that a dust cover 37 is fixedly installed on the inner wall of the dust removal chamber 9. The brush roller 12 and the drive roller 10 are installed inside the dust cover 37, which can suppress dust from flying during the dust removal process. An inlet is provided on the left side of the dust cover 37, and a scraper 38 is provided at the bottom of the inlet. The scraper 38 contacts the outer surface of the primary filter screen 5, which can improve the removal of stubborn stains. An outlet is provided at the bottom of the dust cover 37, and a comb 39 is provided in the middle of the outlet. The comb 39 contacts the brush wheel 14, which can comb the bristles on the surface of the brush wheel 14, and comb the dust on the brush wheel 14 to the outlet, improving the dust removal effect.

[0025] Example 5: The only difference from Example 1 is that the ozone-free ultraviolet lamp 23 has a tortuous channel on its exterior. This tortuous channel consists of two electrically operated horizontally sliding sunshades 40 spaced vertically apart. The two curtains 40 are staggered horizontally. Both the air quality sensor 42 and the curtains 40 are electrically connected to the control panel 41. The two curtains 40 can change the size of the inlet and outlet of the tortuous channel, adjusting the degree of tortuosity (affecting airflow velocity and reaction path length) and the degree of shielding of the ozone-free ultraviolet lamp 23 (affecting the air temperature for the reaction), allowing ozone to undergo a complete decomposition reaction upon passage.

[0026] The electrically operated horizontal sliding sunshade 40 includes a roller 43, a roller blind fabric 44, and a horizontal sliding rod 45. The roller blind fabric 44 is fixedly connected to the roller 43 and the horizontal sliding rod 45 at both ends. One end of the roller 43 is connected to a roller blind motor 46. A winding wheel 47 is fixedly installed at the output end of the roller blind motor 46. The horizontal sliding rod 45 is slidably mounted on the inner wall of the airflow channel 4 via a transverse guide rail 48. A pulley 49 is rotatably mounted at one end of the transverse guide rail 48, and a pull rope 50 is mounted on the pulley 49. The two ends of the pull rope 50 are fixedly connected to the winding wheel 47 and the horizontal sliding rod 45, respectively. When the air quality sensor 42 detects that the ozone content in the air at the air outlet is too high, as shown in the attached... Figure 2As shown, taking the movement of the lower-side electric horizontal sliding sunshade 40 as an example, when the roller blind motor 46 drives the roller shaft 43 to rotate counterclockwise, the roller shaft 43 releases the roller blind fabric 44, and the winding wheel 47 rotates counterclockwise to wind up the pull rope 50. The pull rope 50 pulls the horizontal moving rod 45 to the left, unfolding the roller blind fabric 44, thus narrowing the outlet of the tortuous channel (the inlet of the tortuous channel undergoes the same change), increasing the reaction path length, raising the air temperature, and allowing ozone to decompose fully. When the ozone content in the air at the air outlet is not high, when the roller blind motor 46 drives the roller shaft 43 to rotate clockwise, the outlet of the tortuous channel expands (the inlet of the tortuous channel undergoes the same change), increasing the airflow velocity. In addition, a nano-silver catalytic coating can be optionally provided on the inner wall of the roller blind fabric 44 to provide the rate of ozone catalytic decomposition and the performance of the roller blind fabric 44 in blocking ultraviolet rays, thereby enhancing the degree of ozone decomposition reaction.

[0027] Example 6: The only difference from Example 1 is that a light guide bracket 25 is fixedly installed between the upper ends of the two light guide plates 24. A fiber optic lamp head 26 with a felt texture is located on the upper side of the light guide bracket 25, and an activated carbon impeller 27 is rotatably installed on the lower side of the light guide bracket 25. The fiber optic lamp head 26 and the light guide bracket 25 can release the ultraviolet light from the light guide plates 24 into the center of the ozone gas, solving the problem of low internal ozone decomposition efficiency caused by the difficulty of ultraviolet light from both sides penetrating the outer layer of the ozone gas. The activated carbon impeller 27 can rotate with the airflow, agitating the ozone gas to disperse it evenly while adsorbing bacteria and viruses, thus improving the efficiency of the ozone decomposition reaction.
