DETAILED DESCRIPTION

[0017] A sterilizing and disinfecting air purifier is provided with a control display (1) and a temperature and humidity meter (2) on the outside, and a sterilizing and disinfecting box (3) and a condensing box (4) on the inside; the sterilizing and disinfecting box is surrounded by a heat preservation plate (5), a sterilizing and disinfecting liquid (6) is added in the box, and a liquid discharge valve (7), a heater (8), a micro-bubble generator (9), a circulating pump (10), a liquid level sensor (11), a temperature sensor (12), a liquid replenishing port (13), an ultraviolet lamp spoiler (14), a semiconductor refrigeration spoiler (15) and an air outlet (16) are also provided. The liquid outlet (17) of the pump is connected to the main air inlet channel (18) of the purifier, and a check valve (19) and a coarse filter (20) are arranged at the air inlet of the main air inlet channel from the inside to the outside; the bottom of the condensation box is connected to the air outlet (16) of the disinfection and sterilization box through another air inlet channel (21), and the condensation box is provided with a liquid discharge valve (22), an air inlet (23), a condensation screen (24), a semiconductor cold trap (25), a temperature sensor (26), a semiconductor refrigeration spoiler (27) and an air outlet, and the air outlet is provided with a filter (28), a heater (29) and an air extraction device (30) from the inside to the outside.

[0018] When the purifier is in use, the circulating pump (10) draws the disinfectant and sterilizing liquid (6) with a relatively high temperature to the liquid inlet end (31) of the microbubble generator, and causes the disinfectant and sterilizing liquid to be ejected from the liquid outlet end (32) of the microbubble generator. When the disinfectant and sterilizing liquid passes through the diameter change portion (33) of the microbubble generator, the pressure at the diameter change portion (33) suddenly decreases, so that the air (34) to be purified enters the annular cavity (35) of the microbubble generator through the total air inlet channel (18), and is sucked into the microbubble generator through the micropores (36) at the diameter change portion, and meets the disinfectant and sterilizing liquid passing through the diameter change portion of the microbubble generator at this time. The disinfectant and sterilizing liquid with a high flow rate breaks the bubbles into tiny bubbles, thereby increasing the contact area between the air and the disinfectant and sterilizing liquid, and improving the effects of sterilization and dust removal. The bubbles that have been sterilized are heated to become gases with high temperature and humidity, and overflow from the sterilizing liquid. When the overflowing gas rises to the ultraviolet lamp spoiler (14) and the semiconductor refrigeration spoiler (15), the temperature drops, and the vaporized liquid brought out condenses into drops on the spoiler (14 / 15) and falls back into the sterilizing liquid (6). The air with high temperature and humidity that flows out from the semiconductor refrigeration spoiler (15) enters the condensation box (4) from the air outlet (16) of the sterilizing box, and is further cooled and dehumidified in the condensation box.

[0019] The air entering the condenser is already virus-free, bacteria-free and dust-free clean air, but its humidity and temperature are still relatively high. Therefore, when the air entering the condenser passes through the condensing mesh (24), a part of the vaporized liquid in the air will adhere to the condensing mesh and be removed from the air. The vaporized liquid that is not removed will rise with the air to the semiconductor refrigeration spoiler (27) of the condenser. When it contacts the semiconductor refrigeration spoiler (27), in addition to the temperature drop, the vaporized liquid it carries will condense into droplets on the semiconductor refrigeration spoiler (27) and be removed. The cold air passing through the semiconductor refrigeration spoiler area of ​​the condenser will finally pass through the air outlet of the condenser. When passing through the air outlet, the heater at the air outlet will adjust the temperature of the air according to the setting of the control display (1), and finally become sterile, virus-free, dust-free and clean air (37) with suitable temperature and humidity. Since all viruses are composed of nucleic acids (DNA or RNA) wrapped in a protein shell, and the main chemical components of the bacterial cell wall are polysaccharides or polypeptides, and the inner cell membrane is mainly composed of proteins, lipids and a small amount of sugars, when the temperature of the sterilizing liquid reaches 60°C, the proteins of the viruses and bacteria are denatured due to heat, thereby dying and losing their infection function. The present invention can control the sterilization intensity of the air purifier and shorten the sterilization time by adjusting the heating intensity of the heater (8) in the sterilizing box; according to the principle of vaporization and liquefaction, the humidity of the purified air can be adjusted by adjusting the cooling intensity of the semiconductor refrigeration spoiler (15 / 27) in the sterilizing box and the condensing box; and the outlet temperature of the purified air at the outlet can be controlled by controlling the heating intensity of the heater (29) at the outlet of the condensing box.
