[0045] A receiving groove 26 and an exhaust cavity 27 are provided in the purification box 3, a sealing box 28 is provided in the receiving groove 26, an activated carbon plate 29 is provided in the sealing box 28, an air flow groove 30 is provided between the first induced draft box 1 and the second induced draft box 2 and the receiving groove 26, an exhaust groove 31 is provided between the receiving groove 26 and the exhaust cavity 27, an air pressure sensor 1 32 is installed in the air flow groove 30, an air pressure sensor 2 33 is installed in the exhaust groove 31, the air pressure sensor 1 32 and the air pressure sensor 2 33 are both connected to the control unit 23, and an air inlet 34 and an exhaust port 35 are respectively provided at the sealed bottom and top, and the air inlet 34 and the exhaust port 35 correspond to the air flow groove 30 and the exhaust groove 31 respectively.

[0046] When the present invention is in use, when the purified gas passes through the air flow groove 30 before passing through the activated carbon plate 29, the air pressure sensor 1 32 can detect the air pressure. When the purified gas passes through the exhaust groove 31, the air pressure sensor 2 33 can detect the air pressure. Then, the air pressure values ​​on both sides of the sealing plate can be displayed through the digital display 25. When the activated carbon plate 29 is first used, the air pressure values ​​on both sides are close. When the difference between the air pressure values ​​on both sides is large, it means that the activated carbon plate 29 has been used for a long time. When the air pressure value detected by the air pressure sensor 2 33 is close to the normal value, the activated carbon plate 29 needs to be replaced in time.

[0047] Working principle of the present invention: When the present invention is in use, when the kitchen needs to process steam, the motor 6 is started through the switch group 24, and the motor 6 can drive the induced draft impeller 4 to rotate, so that the steam can be absorbed through the steam processing tube 8, and the steam enters the steam processing tube 8. When passing through the desiccant plate 11, the moisture in the steam can be absorbed, and the dried gas can enter the sealed box 28 through the air flow groove 30. When passing through the activated carbon plate 29, the odor and harmful substances in the gas can be adsorbed and purified, and the purified gas can finally be discharged through the exhaust chamber 27. When the oil fume needs to be processed, the motor 27 is started through the switch group 24, and the motor 27 can drive the induced draft impeller 25 to rotate, so that the oil fume can be absorbed through the oil fume processing tube 9. After the oil fume enters the oil fume processing tube 9, most of the oil fume can adhere to the filter screen plate 42 and the inner wall of the oil fume processing tube 9, and then the gas can enter the sealed box 28 through the air flow groove 30. When passing through the activated carbon plate 29, the odor and harmful substances in the gas can be adsorbed and purified, and the purified gas can finally be discharged through the exhaust chamber 27.

[0048] After the desiccant plate 11 inside the steam treatment tube 8 has been used for a long time, the threaded tube 10 can be unscrewed to replace the desiccant plate 11. When there is a lot of oil smoke attached to the inner wall of the oil fume treatment tube 9 and the filter screen plate 42, the filter screen plate 42 can be removed to complete the cleaning. When the inner wall of the oil fume treatment tube 9 is cleaned, the micro oil pump 19 and the hydraulic cylinder 13 are started through the switch group 24, so that the micro oil pump 19 can pump the detergent in the storage chamber 18 into the transition chamber 16. As the hydraulic pressure increases, the spring 40 can be squeezed and the opening and closing piece 41 can be pushed, so that the detergent can enter the inner cavity and finally sprayed into the oil fume treatment tube 9 through the drainage hole 39. On the inner wall of the oil fume treatment tube 9, the hydraulic cylinder 13 can drive the cleaning frame 14 to move up and down, so that the brush layer 15 can brush the inner wall of the oil fume treatment tube 9, thereby completing the cleaning, and it is very labor-saving. When the amount of detergent in the storage chamber 18 is sufficient, the liquid sensor 20 can sense the detergent liquid, so the indicator light 21 can be turned on by the control unit 23, thereby prompting that the amount of detergent is sufficient. When the detergent is consumed more and the liquid level is lower than the liquid sensor 20, the liquid sensor 20 can no longer sense the liquid information, so the indicator light 21 will go out, so that the detergent needs to be added at the same time.

[0049] The present invention can detect the use of the activated carbon plate 29 when in use. When the purified gas passes through the air flow groove 30 before passing through the activated carbon plate 29, the air pressure sensor 1 32 can detect the air pressure. When the purified gas passes through the exhaust groove 31, the air pressure sensor 2 33 can detect the air pressure. Then, the air pressure values ​​on both sides of the sealing plate can be displayed through the digital display 25. When the activated carbon plate 29 is first used, the air pressure values ​​on both sides are close. When the difference between the air pressure values ​​on both sides is large, it means that the activated carbon plate 29 has been used for a long time. When the air pressure value detected by the air pressure sensor 2 33 is close to the normal value, the activated carbon plate 29 needs to be replaced in time.

[0050] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
