The through holes are uniformly distributed on the partition plate.

The bottom of the box body is provided with a plurality of universal wheels.

The smoke concentration detector A is arranged on the left side wall of the box body.

The utility model has the advantages of it is following: the utility model discloses compact structure, can the filtering bacterium in the air, handle the flue gas more thoroughly, degree of automation is high.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure, 1-a box body, 2-a blower, 3-an exhaust fan, 4-a smoke concentration detector A, 5-a partition plate, 6-a smoke processor, 7-a filter screen, 8-an air inlet cavity, 9-a through hole, 10-a buffer cavity, 11-a smoke concentration detector B, 12-a purified air outlet, 13-a butterfly valve and 14-a universal wheel.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1, a novel ventilation cabinet for purifying air, it includes box 1, controller, air-blower 2 and air exhauster 3, be provided with smoke concentration detector a4 on the lateral wall of box 1, smoke concentration detector a4 sets up on the left side wall of box 1, in box 1 and from lower to upper set gradually germ filtering device, baffle 5 and flue gas treater 6, germ filtering device includes two filter screens 7 that set firmly between the lateral wall about box 1, is filled with the charcoal layer between two filter screens 7, forms air inlet chamber 8 between the filter screen 7 that is located the lower floor and the box 1 bottom, a plurality of through-holes 9 have been seted up on the baffle 5, through-hole 9 evenly distributed is on baffle 5 in this embodiment, be formed with buffer chamber 10 between flue gas treater 6 and the box 1 top, be provided with smoke concentration detector B11 in the buffer chamber 10.

An air outlet of the air blower 2 is communicated with the air inlet cavity 8, an air suction opening of the exhaust fan 3 is communicated with the buffer cavity 10, and an air outlet of the exhaust fan 3 is communicated with the air inlet cavity 8; be provided with the clean wind export 12 of intercommunication cushion chamber 10 on the lateral wall of box 1, clean wind export 12 department is connected with butterfly valve 13, the controller is connected with air-blower 2, air exhauster 3, butterfly valve 13, smog concentration detector A4 and smog concentration detector B11. In the initial state, the blower 2, the exhaust fan 3 and the butterfly valve 13 are all in the closed state, and the controller can control the blower 2, the exhaust fan 3 and the butterfly valve 13 to be started or closed.

As shown in fig. 1, the bottom of the box 1 is provided with a plurality of universal wheels 14, which facilitates the movement of the fume hood.

The working process of the utility model is as follows: the fume hood is placed in public, when the smoke concentration detector A4 detects the smoke in the air, the smoke concentration detector A4 sends an electric signal to the controller, the controller receives the electric signal and controls the blower 2 to start, the blower 2 draws air into the air inlet cavity 8, air carrying smoke and germs under air pressure passes through the lower filter screen 7 to enter the charcoal layer, charcoal of the charcoal layer adsorbs harmful germs in the air, air without harmful germs sequentially passes through the upper filter screen 7 and the through holes 9 to enter the smoke processor 6 under air pressure, the smoke processor 6 absorbs the smoke in the air, the processed air enters the buffer cavity 10, the smoke concentration detector B11 detects whether the air still contains smoke in real time, if so, an electric signal is sent to the controller, the controller controls the butterfly valve 13 to be opened, and the clean air in the buffer cavity 10 is discharged from the purified air outlet 12; if it still contains the flue gas to detect, then send the signal of telecommunication for the controller, controller control air exhauster 3 starts, and air suction in the air inlet chamber 8 with the air suction in buffer chamber 10 is in order to continue to handle, until not containing the flue gas, has consequently realized circulation filtering flue gas, and the filtering flue gas is more thorough. In addition, infectious germs in the air can be adsorbed through the charcoal layer, the infection of the winter influenza is effectively prevented, meanwhile, the smoke is automatically detected and monitored, and the device has the characteristic of high automation degree.
