the active filter comprises a cabinet body, wherein an opening and closing door is arranged on the front surface of the cabinet body, an air inlet column is arranged at a position, close to the bottom, of the front surface of the opening and closing door, a gas collecting frame is fixed on the back surface of the air inlet column, a flow guide pipe is arranged on the back surface of the gas collecting frame, a limit box is fixed on the bottom of the inner wall of the cabinet body, the right side of the limit box is connected with the inner wall of the cabinet body and penetrates through the cabinet body to be communicated with the right side of the cabinet body in an air manner, a drawer box is inserted in the limit box, a dust-proof plate is horizontally fixed in the interior of the drawer box, a partition plate is horizontally fixed on the inner wall of the cabinet body above the limit box, a through pipe on the partition plate is fixed on the top of the limit box, a fan B is embedded in the position, and the side surface and the top of the drawer box are respectively corresponding to the flow guide pipe and the position of the through pipe; the front of the cabinet body is provided with an air outlet fence near the top, the back of the air outlet fence is fixed with a fan frame, and a fan A is embedded in the fan frame.

Preferably: the number of fans B on the partition plate is two.

Preferably: the honeycomb duct is flexible pipe.

Preferably: the inner wall of the limit box is provided with a rubber sealing gasket.

Compared with the prior art, the utility model has the beneficial effects that:

through setting up gas collecting frame, the honeycomb duct, spacing box, drawer box and fan B, the gas collecting frame is used for covering the fence that admits air, make the inside that gets into reach spacing box and drawer box through the honeycomb duct, the dust guard filters the dust in the air afterwards, the inside air flow that increases the cabinet body of internal portion of cabinet of air-out, make the internal portion of cabinet air flow take away the heat through the internal portion of cabinet and get fan A's position, will have the quick fence of giving vent to anger of thermal air to the external portion of cabinet through fan A afterwards, the dust then can stay in drawer box, clear up it through pulling drawer box can, the effect of filtering and collecting the dust has been reached, avoid the dust to get into the cabinet internal and influence the internal portion work of cabinet's problem, fan A and fan B greatly increased the internal portion of cabinet air flow, realize quick radiating effect.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1 to 3, in the embodiment of the utility model, an active filter includes a cabinet body 1, an opening and closing door 2 is disposed on the front surface of the cabinet body 1, an air inlet column 3 is disposed at a position of the front surface of the opening and closing door 2 near the bottom, a gas collecting frame 4 is fixed on the back surface of the air inlet column 3, a flow guide pipe 5 is disposed on the back surface of the gas collecting frame 4, the flow guide pipe 5 is a flexible telescopic pipe, and the function of the flexible telescopic pipe is to ensure that the opening and closing door 2 can be normally opened and the flexible telescopic pipe cannot be bent.

The utility model discloses a cabinet, including cabinet 1, baffle 9, fan B10, baffle 9, air guide pipe 5, through-hole 11, baffle 9, through-pipe and baffle 6 top are fixed to the bottom of cabinet 1 inner wall, the bottom of cabinet 1 inner wall is fixed with spacing box 6, the inner wall of spacing box 6 is provided with rubber seal, the right side of spacing box 6 is connected with cabinet 1's inner wall and passes cabinet 1 and cabinet 1 right side air intercommunication, the inside grafting of spacing box 6 has drawer box 7, the inside level of drawer box 7 is fixed with dust guard 8, the inner wall of cabinet 1 is located the top level of spacing box 6, the siphunculus on baffle 9 is fixed with baffle 6 top, and the siphunculus on the baffle 9 communicates with spacing box 6, the quantity of fan B10 is two sets of on the baffle 9, the position on-pipe inside is embedded has fan B10 on the baffle 9, the through-hole 11 has all been seted up to the side and the top of drawer box 7 respectively corresponding honeycomb duct 5 and siphunculus.
