[0028] The present application is further described in detail below through drawings and examples.

[0029] Reference Figures 1 to 4 The embodiment of the present application provides a fume hood with an air purification structure, including a bottom box 1, a side panel 5 is fixedly installed on the top of the bottom box 1, a top box 4 is fixedly installed on the top of the side panel 5, a ventilation component 3 is arranged on the top of the top box 4, a purification component 2 is arranged inside the top box 4, the purification component 2 includes an activated carbon filter plate 21 and a dust filter plate 22, a partition 24 is fixedly installed inside the top box 4, the activated carbon filter plate 21 and the dust filter plate 22 are plugged into the inside of the top box 4 and are located on both sides of the partition 24, card plates 25 are fixedly installed on both sides of the partition 24, the inner ends of the activated carbon filter plate 21 and the dust filter plate 22 are plugged into the inner side of the card plate 25, and an air inlet groove 23 is opened at the bottom of the top box 4.

[0030] The left and right sides of the partition 24 are both provided with an activated carbon filter plate 21 and a dust filter plate 22. The activated carbon filter plate 21 is located above the dust filter plate 22. The front, back, left, and right sides of the activated carbon filter plate 21 are all in contact with the inner wall of the top box 4 and the side wall of the partition 24. The outer ends of the activated carbon filter plate 21 and the dust filter plate 22 are both fixedly installed with a fixing plate 26. The fixing plate 26 is located on the outside of the top box 4. The outer side of the top box 4 is fixedly installed with a threaded column 28. The upper and lower sides of the fixing plate 26 are both fixedly installed with a fixing block 27. The threaded column 28 is inserted into the corresponding fixing block 27. The outer side of the threaded column 28 is screwed with a nut 29. The nut 29 is located on the outer side of the fixing block 27.

[0031] In the present embodiment, when the cabinet is ventilated, the gas enters the top box 4 through the air inlet groove 23. The gas entering the top box 4 first passes through the dust filter plate 22. The dust filter plate 22 absorbs large particles of dust in the gas. After absorption, the gas passes through the activated carbon filter plate 21 again. The activated carbon filter plate 21 can absorb small particles and harmful gases in the gas, thereby achieving the purification effect of the exhaust gas and reducing pollution to the environment. When the dust filter plate 22 and the activated carbon filter plate 21 need to be replaced, the nut 29 is removed to release the fixation of the fixing block 27 and the fixing plate 26. The internal dust filter plate 22 and the activated carbon filter plate 21 can be pulled out through the fixing plate 26, and the dust filter plate 22 and the activated carbon filter plate 21 can be cleaned and reinstalled after cleaning, thereby achieving the purpose of convenient disassembly and cleaning of the dust filter plate 22 and the activated carbon filter plate 21.

[0032] Reference Figures 1 to 4 In one aspect of the present embodiment, the ventilation assembly 3 includes a first air pump 31 and a second air pump 32, both of which are fixedly installed on the top of the top box 4, and a first air intake pipe 33 is fixedly installed at the inlet of the first air pump 31, and a second air intake pipe 34 is fixedly installed at the inlet of the second air pump 32. The first air intake pipe 33 and the second air intake pipe 34 are both connected to the interior of the top box 4, the first air intake pipe 33 is connected to the left side of the partition 24, and the second air intake pipe 34 is connected to the right side of the partition 24.

[0033] The outlet of the first air pump 31 is fixedly installed with a first air outlet pipe 35, the outlet of the second air pump 32 is fixedly installed with a second air outlet pipe 36, and the top of the top box 4 is fixedly installed with a main pipeline 37, and the first air outlet pipe 35 and the second air outlet pipe 36 are both connected to the main pipeline 37. The first air outlet pipe 35 and the second air outlet pipe 36 are both connected to the main pipeline 37 through a one-way valve 38, and the connection direction of the one-way valve 38 is from the first air outlet pipe 35 to the main pipeline 37, and from the second air outlet pipe 36 to the main pipeline 37.

[0034] In this embodiment, during ventilation, the air inside the top box 4 is extracted by starting the first vacuum pump 31 and the second vacuum pump 32 above and through the first air inlet pipe 33 and the second air inlet pipe 34, thereby generating a negative pressure inside the top box 4, thereby sucking in external air through the air inlet groove 23 below. By starting the first and second vacuum pumps on the left and right sides separately and synchronously, the left half and the right half can be ventilated separately, as well as the entire box can be ventilated. This method can reduce the overall power consumption when the fume hood is used for single-sided operation; the wind exhausted on both sides enters the column duct through the first and second air outlet pipes and is discharged.

[0035] Working principle: When the cabinet is ventilated, the gas enters the top box 4 through the air inlet slot 23. The gas entering the top box 4 first passes through the dust filter plate 22. The dust filter plate 22 absorbs large particles of dust in the gas. After absorption, the gas passes through the activated carbon filter plate 21 again. The activated carbon filter plate 21 can absorb small particles and harmful gases in the gas, thereby achieving a purification effect on the exhaust gas and reducing pollution to the environment. When it is necessary to replace the dust filter plate 22 and the activated carbon filter plate 21, the nut 29 is removed to release the fixation of the fixing block 27 and the fixing plate 26. The internal dust filter plate 22 and the activated carbon filter plate 21 can be pulled out through the fixing plate 26, and the dust filter plate 22 and the activated carbon filter plate 21 can be replaced. The dust filter plate 22 and the activated carbon filter plate 21 are conveniently disassembled and cleaned, and the air inside the top box 4 is extracted through the first air inlet pipe 33 and the second air inlet pipe 34 by starting the first air pump 31 and the second air pump 32 above, thereby generating negative pressure inside the top box 4, and sucking in external air through the air inlet groove 23 below. By starting the first and second air pumps on the left and right sides separately and synchronously, the left half and the right half can be ventilated separately, as well as the whole can be ventilated. This method can reduce the overall power consumption when using the fume hood for single-sided operation; the wind exhausted on both sides enters the column duct through the first and second air outlet pipes and is discharged.
