Description
Technical Field
[0001] The invention relates to the technical field of plasma sterilization equipment, in particular to plasma air disinfection equipment. Background Art
[0002] Plasma disinfection uses a bipolar plasma electrostatic field to decompose and destroy negatively charged bacteria, polarize and adsorb dust, and then combines components such as drug-impregnated activated carbon, electrostatic nets, and photocatalytic devices for secondary sterilization and filtration. The treated clean air circulates rapidly in large quantities to maintain the controlled environment at the "sterile clean room" standard. The sterilization is rapid and thorough, with a sterilization rate of 100% for natural bacteria in the air within 30 minutes, and more than 99% for Escherichia coli, Staphylococcus aureus, and Candida albicans within 40 minutes. 45 minutes after starting up, the airborne settling bacteria are ≤15 CFU / dish·30MIN, and the floating bacteria in the air are ≤800 / m 3 , the air cleanliness reaches 300,000 levels (ISO9 standard) and above, and can reach up to 100 levels. With the increasing awareness of environmental pollution and the deterioration of air quality, in order to improve the quality of indoor air, plasma air purifiers are often used. The fan is used to draw the air in the room into the plasma purifier, and the plasma effect of the plasma purifier is used to purify the air, so that the indoor air can reach a fresh effect.
[0003] Chinese patent CN212204863U discloses a plasma disinfection and sterilization air purification device. This device, which combines a plasma generation module (a), an electrostatic adsorption module, and a plasma generation module (b), effectively kills harmful microorganisms in the air flowing through the purifier's air duct by combining fast pulse high voltage direct killing, electrostatic adsorption, and strong oxidative active particle disinfection. This triple-action kill method overcomes the performance degradation and adsorption-based disinfection drawbacks of traditional electrostatic technologies that suffer from long-term use. The particle filtration module, plasma generation module (a), electrostatic adsorption module, plasma generation module (b), and ozone removal module are all designed to be retractable, making them easy to repair and replace if problems arise.

[0037] The working principle of the present invention is as follows: when air is disinfected, the air enters the plasma disinfector 1 through the air inlet 2. Before the air enters the plasma disinfector 1, the air is first filtered by the filter assembly to prevent dust in the air from entering the plasma disinfector 1. When there is a lot of dust accumulated on the filter assembly, the fixed box 3 is pulled out from the air outlet, and then the filter assembly is pulled out from the slot 301 for cleaning. After the cleaning is completed, the filter assembly is inserted into the slot 301, and then the fixed box 3 is inserted into the air outlet. After the fixed box 3 is placed in the air inlet 2, the sealing strip 7 is inflated by the adjusting mechanism, and the plug rod 10 is pushed The piston 11 moves toward the fixed box 3. When the piston 11 moves, the gas in the cylinder 8 is input into the sealing strip 7 through the gas pipe 12, so that the sealing strip 7 expands to improve the sealing performance. In the process of inserting the fixed box 3 into the air inlet 2, the gas in the sealing strip 7 can be extracted to shrink the sealing strip 7, thereby preventing the sealing strip 7 from hindering the fixed box 3 from being inserted into the air inlet 2, so as to facilitate the insertion of the fixed box 3 into the air inlet 2; when it is necessary to clean the filter 6, the two pull rings 9 are pulled outwards. When the pull rings 9 move, the plug rod 10 is moved, thereby driving the piston 11 to move in the direction away from the fixed box 3, thereby sucking the gas in the sealing strip 7 into the cylinder 8, so that The sealing strip 7 contracts, so that the fixing box 3 can slide relative to the air inlet 2, so that the fixing box 3 can be taken out more conveniently. The sealing strip 7 can be contracted and the fixing box 3 can be drawn out from the air inlet 2 by only pulling the pull ring 9. When installing the fixing box 3, after the fixing box 3 is inserted into the air inlet 2, the piston 11 is first pushed to move by the plug rod 10 to expand the sealing strip 7, and then the plug rod 10 is rotated to make the plug rod 10 threadedly connected to the cylinder 8 through the first thread groove 1001, and then the plug rod 10 is rotated to make the piston 11 move to the left to the limit position. The setting of the first thread groove 1001 makes the plug The rod 10 can be self-locking, and on the other hand, it makes it easier for the gas in the cylinder 8 to squeeze into the sealing strip 7; when the fixing box 3 is slid out of the air inlet 2, the second threaded groove 1002 just contacts the cylinder 8, and the first traction rope 14 is just in a taut state, and then the pull ring 9 is rotated. When the pull ring 9 rotates, it drives the plug rod 10 to rotate, so that the plug rod 10 moves to the right, thereby driving the piston 11 to move to the right. When the piston 11 moves to the right, it pulls the first traction rope 14 to move to the right, thereby driving the top plate 16 to move upward through the second traction rope 15, thereby lifting the installation frame 5 upward, and moving the plug plate 4 out of the slot 301, so as to facilitate the removal of the installation frame 5.
