[0030] During implementation, the user tightens the bolt body 4033 on the surface of the installation box 401, and installs the installation box 401 on the inner wall of the device body 1 under the action of the bolt body 4033. The interior of the device body 1 is deodorized through the through-hole body 402 under the action of the deodorizing layer 4031, and the interior of the device body 1 is sterilized through the through-hole body 402 under the action of the sterilization layer 4032. This makes it difficult for the interior of the device body 1 to breed bacteria and odor, while having a certain sterilization effect, so as to realize the function of the purification device to deodorize and sterilize the interior of the device body 1.

[0031] Working principle: When in use, first place the device body 1 at the designated position, and the user places the mounting tube 113 on the surface of the fixed tube 116, so that the mounting tube 113 drives the second magnet 302 to move to contact the surface of the first magnet 301, and the mounting tube 113 is installed on the surface of the fixed tube 116 under the magnetic attraction of the first magnet 301 and the second magnet 302.

[0032] Subsequently, the user operates the control button 101, so that the control button 101 controls the range hood 103 to work. Under the action of the range hood 103, the oil smoke is sucked into the interior of the mounting tube 113, and enters the interior of the device body 1 through the mounting tube 113 and the fixed tube 116. The user then operates the control button 101, so that the control button 101 controls the induced draft unit 114 to work. Under the action of the induced draft unit 114, the oil smoke is sucked. Subsequently, under the action of the purifier 110, the smoke particles in the oil smoke are filtered, and some harmful substances in the oil smoke can be absorbed by the purifier 110 and then discharged to the surface of the absorption plate 115. Some fine oil stains in the oil smoke are absorbed by the absorption plate 115 and the filter screen plate 109, so that the oil smoke in the kitchen can be removed.

When it is detected that the discharged gas meets the standard, the valve 105 on the surface of the tube body 108 can be controlled to open, so that the gas is discharged to the outside through the tube body 108 and the assembly tube 104. When it is detected that the discharged gas does not meet the standard, the gas enters the interior of the assembly tube 104, and the oil fume detector 107 will send a signal. The user operates the control button 101, so that the control button 101 controls the air pump body 111 to work. Under the action of the air pump body 111, the gas that does not meet the standard inside the valve 105 is sucked into the interior of the air outlet pipe 112 through the suction pipe 106, and the process is repeated until it meets the standard and is discharged through the tube body 108 and the assembly pipe 104.

[0033] Subsequently, the user needs to replace the absorption plate 115 regularly. The user pulls the connecting piece 2032 upwards so that the connecting piece 2032 drives the absorption plate 115 to move inside the device body 1, so that the absorption plate 115 drives the positioning block 201 away from the inner wall of the device body 1. At this time, the absorption plate 115 drives the guide slider 202 to slide inside the guide slot 2031. Under the joint action of the guide slider 202 and the guide slot 2031, the absorption plate 115 is guided, so that the absorption plate 115 is pulled out from the inside of the device body 1, and the absorption plate 115 is replaced to realize the function of quickly replacing the absorption plate 115 of the purification device, so that the user can conveniently replace the absorption plate 115 when using the purification device, so that the purification device has a better treatment effect on oil smoke and a better use effect.

[0034] Subsequently, the user tightens the bolt body 4033 on the surface of the installation box 401, and installs the installation box 401 on the inner wall of the device body 1 under the action of the bolt body 4033, and deodorizes the interior of the device body 1 through the through-hole body 402 under the action of the deodorizing layer 4031, and sterilizes the interior of the device body 1 through the through-hole body 402 under the action of the sterilization layer 4032, so that the interior of the device body 1 is not easy to breed bacteria and odor, and has a certain sterilization effect, so as to realize the function of the purification device to deodorize and sterilize the interior of the device body 1, so that when the purification device is used, the phenomenon of odor inside the device body 1 can be avoided, and the purification device can sterilize the inside of the device body 1, making the purification device more practical when used, and finally completing the use of the purification device.
