Description of the drawings:

FIG. 1 is a drawing of an induced air structure of the utility model, which adopts the outer glass and the jet flow surface vertically staggered;

figure 2 is the induced draft structure chart of the utility model which adopts the outer glass and the jet flow surface on the same vertical plane.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to a ventilation exhaust system in laboratory specifically includes outer glass 1 and inlayer glass 2, corresponds unit layer 3 in the inlayer glass 2, form the ventiduct between outer glass 1 and the inlayer glass 2, the ventiduct bottom sets up first fan 4, leaves wind groove 5 between inlayer glass 2 and the top of unit layer 3, disposes first consumptive material 51 in each wind groove 5, first consumptive material 51 mainly filters the outside air current that gets into unit layer 3, disposes the jet surface 6 that the slope set up between each wind groove 5 and the outer glass 1, jet surface 6 makes the ventiduct below that corresponds each unit layer 3 big, the top is little. When the first fan 4 acts, the wind flow is upward, the wind flow is compressed along with the inclination angle of the jet flow surface 6 when passing through the jet flow surface 6, and then is ejected out from the vacancy between the upper end of the jet flow surface 6 and the inner layer glass 2, so that negative pressure can be formed at the wind groove 5 of each unit layer 3, further indoor foul air is brought out, and pneumatic physical exhaust is formed. By adopting the technical scheme, the outer side of the air duct 5 of each unit layer 3 can be kept at a certain negative pressure, and the phenomenon that the exhaust effect is weakened due to the height of the unit layer 3 is avoided.

The jet flow nozzle formed between the upper end of the jet flow surface 6 and the inner layer glass 2 is arranged above the air groove 5 corresponding to the unit layer 3, namely the jet flow port formed between the jet flow surface 6 and the inner layer glass 2 is higher than the corresponding air groove 5, the distance from the air groove 5 is preferably greater than 20cm, the ascending air flow is gradually compressed between the jet flow surface 6 and the inner layer glass, the air below is continuously blown upwards vertically, thus the air flow can be prevented from being poured into the unit layer 3, the negative pressure is directly formed to carry the gas in the unit layer 3, and the gas is sprayed upwards from the jet flow nozzle.

In order to strengthen the vertical wind flow of the air duct, the top end of the air duct is provided with a second fan 7, so that the vertical wind flow is further strengthened, and a better jet effect is realized.

The jet flow surface 6 is connected with the driving mechanism 8, so that the inclination amplitude of the jet flow surface 6 can be adjusted, the compression amount of the wind flow on the unit layer 3 is further changed, the negative pressure amount outside the wind groove 5 is changed, and different jet flow effects are realized.

The hydraulic stem of actuating mechanism 8 for being located the 6 upper portion both sides of efflux face, through the hydraulic pump drive of indoor connection, can punch at inlayer glass 2, make the connecting pipe between hydraulic stem and the hydraulic pump pass, and efflux face 6 lower extreme can adopt metal connecting piece and configuration pivot to be connected to outer glass 1 on, make efflux face 6 under actuating mechanism 8's drive use the pivot in the metal connecting piece as the fulcrum swing can, like this alright correspond the swing range of efflux face 6 of unit layer 3 at indoor control. Because the ventilation duct does not need to be completely sealed, the driving mechanism 8 can also adopt a driving mode of a motor and a belt pulley, and any mechanical mechanism capable of adjusting the swing amplitude of the jet surface 6 can be adopted under the condition of not considering the appearance.

The matching of the jet flow surface 6 and the outer layer glass 1 can have two modes, one mode is that the outer layer glass 1 is vertically arranged, the jet flow surface 6 is arranged close to the outer layer glass 1 in a staggered mode in the vertical direction, and the lower end of the jet flow surface 6 is connected onto the outer layer glass 1 by adopting a metal connecting piece, so that the jet flow surface 6 can swing under the driving of a driving mechanism 8 by taking the metal connecting piece as a fulcrum, and the jet flow surface 6 in the scheme is preferably made of glass materials and can be prevented from blocking light; the other is that the jet flow surface 6 is in the same plane with the outer glass 1 when in a vertical state, as shown in fig. 2, namely, the outer glass 1 and the jet flow surface 6 are vertically and upwardly arranged at intervals, so that a certain vent is formed between the jet flow surface 6 and the outer glass 1 above the jet flow surface 6 under the condition that the jet flow surface 6 has an inclined angle, and negative pressure is also formed at the vent under the jet flow state, so that outside air enters the ventilation channel and is upwards driven.

When adopting outer glass 1 and the perpendicular setting of staggering of efflux face 6, then the inside relative seal of ventiduct, consequently first fan 4 can be configured with second consumptive material 9, filters the distinguished and admirable wind that introduces. When a certain unit layer 3 needs to be quickly ventilated, the upper end of the jet flow surface 6 is close to the inner layer glass 2 as far as possible or is directly contacted with the inner layer glass 2 by adjusting the inclination angle of the jet flow surface 6, the formed jet flow nozzle is smaller, even the jet flow nozzle is directly closed, and then the wind flow can be poured into a room at the wind groove 5 of the unit layer 3 to change the indoor gas.

The first consumable 51 and the second consumable 9 can be made of HEPA filter material.

Furthermore, the bottom of each inner layer glass 2 is provided with an air exchange layer 21, the upper part of the air exchange layer 21 is connected with the wall of the unit layer 3 through a folding rod 22, and the folding rod 22 is the prior art, in particular to the prior door and window switch linkage mechanism and plays the roles of limiting and pulling; the lower part of the ventilation layer 21 is connected with the bottom surface of the unit layer 3 through a shaft, the upper part of the ventilation layer 21 can be opened and closed outwards by manually pushing and pulling the upper part of the ventilation layer 21, and the ventilation layer 21 can be made of metal or glass. After setting up like this, when needing to form the extrinsic cycle and take a breath, only need dispose timing regulator regulation actuating mechanism 8, or means short time operation actuating mechanism 8 constantly opens and shuts the action, make the reciprocal change of inclination of efflux face 6, the efflux spout constantly opens and shuts, meanwhile, the layer 21 of taking a breath of this unit layer 3 lower part needs to be opened, then the gas filtered through first consumptive material 51 pours into unit layer 3 from upper portion wind channel 5 into, the polluted gas in this unit layer 3 then gets into the ventiduct from layer 21 of taking a breath, under the effect of the efflux face 6 of constantly changing inclination, the gas of changing can get into the upper strata when the efflux spout is opened, the unit layer is poured into after the first consumptive material 51 that the wind channel 5 was crossed to the air current when the efflux spout is closed, constantly change the gas in the unit layer 3, realize the purpose of high-efficient taking a breath.

It is to be understood that the technical scope of the present invention is not limited to the content of the specification, and that modifications or changes may be made by those skilled in the art based on the above description, and all such modifications and changes are intended to fall within the scope of the appended claims.
