DETAILED DESCRIPTION
[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] Example:
[0022] like Figure 1-Figure 2 As shown, the exhaust disinfection structure of the wet heat cleaning and disinfecting machine includes a cleaning cylinder 5 and a machine cover 6, the machine cover 6 is provided with an air inlet 61 and an exhaust port 62 connected to the cleaning cylinder 5, the exhaust port 62 is connected to the gas disinfection treatment box through an exhaust pipe; the gas disinfection treatment box includes a box body 71, the box body 71 is divided into a first purification chamber and a second purification chamber by a primary filter layer 72, an ultrasonic atomizer 73 is provided in the first purification chamber, and an aerosol dissolving liquid or a disinfectant is added to the ultrasonic atomizer 73 through a liquid inlet pipe 732; the second purification chamber is provided with a first conductive plate 74 and a second conductive plate 75 which are relatively distributed on the left and right, the first conductive plate 74 is connected to the positive pole of the high voltage generator, the second conductive plate 75 is connected to the negative pole of the high voltage generator, the first conductive plate 74 is provided with a plurality of discharge plates 741, the discharge plate 741 is provided with a plurality of discharge needles 742, and the second conductive plate 75 is provided with a plurality of adsorption plates 76.
[0023] When the automatic cleaning device completes cleaning, clean and dry gas is introduced through the air inlet 61 on the cover 6 to dry the container and the inside of the device. At the same time, the contaminated gas and aerosol containing viruses and bacteria in the cleaning cylinder 5 are discharged into the gas disinfection treatment box for treatment to prevent the spread of bacteria and to avoid the aerosol containing pathogens in the cleaning container being discharged to pollute the air when the device is opened to take out the cleaning container, thereby causing harm to the operator.
[0024] The ultrasonic atomizer 73 of the first purification chamber in the gas disinfection treatment box atomizes the aerosol dissolving liquid or disinfectant, so that it is fully mixed with the aerosol and the micron-level atomized droplets, and the virus aerosol is captured, dissolved and inactivated. The atomized droplets gradually adhere to the surface of the particles in the aerosol, and the volume increases, which is convenient for filtering and capturing; after passing through the first purification chamber, the aerosol is primary filtered through the primary filter layer 72, and then enters the second purification chamber. The second purification chamber discharges through the tip of the discharge needle 742 to inactivate the virus, and makes the aerosol positively charged. At the same time, the potential difference of the electric field is formed between the first conductive plate 74 and the second conductive plate 75, so that the positively charged aerosol moves to the negative second conductive plate 75 and the adsorption plate 76 under the action of the electric field and is adsorbed on the adsorption plate 76; and the aerosol contains atomized liquid, which enhances the ionization effect of the electric field, so that more aerosol particulate matter is adsorbed, and the purification effect of the aerosol is improved.
[0025] The discharge plates 741 and the adsorption plates 76 are arranged in a staggered manner, and a baffle channel is formed between the discharge plates 741 and the adsorption plates 76. A baffle channel is formed between the discharge plates 741 and the adsorption plates 76, and the aerosol passes through the baffle channel in a curved manner, thereby extending the processing time in the second purification chamber and improving the adsorption efficiency.
[0026] The deflecting channel is provided with a folded fine filter layer, which includes a first filter layer 77 and a second filter layer 78. One end of the first filter layer 77 is connected to the discharge plate 741, and the other end of the first filter layer 77 is connected to the second conductive plate 75; one end of the second filter layer 78 is connected to the adsorption plate 76, and the other end of the second filter layer 78 is connected to the first conductive plate 74. When the aerosol passes through the deflecting channel, it is not only subjected to charge adsorption and discharge sterilization, but also filtered through multiple layers of fine filter layers in sequence to improve the filtering effect. The fine filter layer has a folded structure, which not only increases the filtering area, reduces the passing speed of the aerosol, and prolongs the processing time; it can also allow the fine filter layer to be installed in boxes 71 of different volumes for purification.
[0027] The first purification chamber is also provided with a plurality of diverter plates 734, and ultraviolet disinfection lamps 735 are provided on both sides of the diverter plates 734. The aerosol is diverted by the diverter plates 734 so that the aerosol enters the second purification chamber evenly, thereby improving the purification effect of the second purification chamber; at the same time, the external disinfection lamp can fully and evenly irradiate the aerosol, thereby improving the sterilization effect.
[0028] The adsorption plate 76 includes a conductive core 761, which is connected to the second conductive plate 75, and the conductive core 761 is wrapped with an adsorption layer 762. The adsorption plate 76 adsorbs the positively charged aerosol onto the adsorption layer 762 through the electric field of the conductive core 761. At the same time, the adsorption layer 762 can use activated carbon, titanium dioxide nanoparticles, etc. to purify the aerosol through its own adsorption capacity, forming multiple adsorptions and improving the purification effect.
[0029] The first purification chamber is also provided with a spray head 731, which is connected to a liquid inlet pipe 732, and a control valve 733 is provided between the liquid inlet pipe 732 and the ultrasonic atomizer 73. The spray head 731 can clean the primary filter layer 72, the filter layer and the adsorption layer 762 after purification, and melt the aerosol attached therein, so that they can be reused.
[0030] A one-way valve is provided in the air inlet 61, and the air inlet 61 is connected to the gas filter 63, the gas heater 64 and the fan 65 through the air inlet pipe. The one-way valve of the air inlet 61 is provided to prevent the aerosol from escaping from the air inlet 61; the air in the air inlet 61 is filtered and heated by the gas filter 63 and the gas heater 64, and the clean and dry gas is introduced into the sterilizer for drying.
