Abstract
The invention discloses a ventilating hood for a laboratory, comprising a body which is characterized in that: an air outlet is arranged at the top of the body, a plurality of uniformly spaced exhaust outlets are formed from top to bottom on the back board, left side wall and right side wall of the body, the exhaust outlets are communicated with the air outlet through air pipes, and an exhaust fan is arranged at the air outlet. The ventilating hood for a laboratory has a better air exhaust effect.
Description
Technical field
The present invention relates to a kind of vent cabinet, relate in particular to a kind of ventilation hoods for laboratories.
Background technology
Laboratory ventilation is an indispensable part in the lab design.For laboratory worker is not sucked or swallow the not clear chemical substance of some poisonous, that can cause a disease or toxicity and organism, laboratory in good ventilation should be arranged.For stoping the absorption of some steams, gas and particulate (smog, coal smoke, dust and aerosol), polluter must be removed with the method for vent cabinet, ventilator cowling or local ventilation.
The Chinese patent publication number is CN101537376A, and the patent of invention that open day is on September 23rd, 2009 discloses a kind of laboratory hood, comprises cabinet, is arranged on the positive form door of said cabinet and is arranged on the central controller on the said cabinet; The frame that is positioned at the positive said form door of said cabinet is provided with pyroscan; The said pyroscan signal of telecommunication connects said central controller; The said pyroscan signal of telecommunication connects said central controller, and the signal of telecommunication of said central controller output is controlled the driving mechanism of said form door.Though the laboratory hood of this kind structure is surveyed the infrared ray input signal through said pyroscan; Thereby realize said form door personnel near the time open automatically;, personnel close automatically when leaving, and easy to operate, intelligent high; But because the laboratory hood of this kind structure often only is provided with exhaust outlet at its top; When the circulation of cabinet internal gas has some setbacks, just can't timely and effectively the gas of bottom of cabinet bulk and middle part be discharged, therefore relatively poor defective and the problem of existing vent cabinet ubiquity air draft effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of air draft effect ventilation hoods for laboratories preferably.
For solving the problems of the technologies described above; The present invention provides a kind of ventilation hoods for laboratories; Comprise cabinet, the top of said cabinet is provided with air outlet, evenly spacedly from top to bottom on the backboard of said cabinet and left side wall and the right side wall is provided with a plurality of exhaust outlets; Said exhaust outlet communicates with said air outlet through airduct, and said air outlet place is provided with air exhauster.
Said exhaust outlet place is provided with filter screen.
Said air outlet is arranged on the middle part at said cabinet top.
Compared with prior art, effect intentionally of the present invention is:
Be provided with a plurality of exhaust outlets because a kind of ventilation hoods for laboratories of the present invention is evenly spaced from top to bottom on backboard, left side wall and the right side wall of cabinet; So can be effectively, timely the pernicious gas of bottom of cabinet bulk and middle part is discharged; And do not receive the influence of cabinet internal gas circulation status, so air draft effect of the present invention is better.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: cabinet 2, air outlet 4, air exhauster 6, backboard 8, left side wall 10, right side wall 12, exhaust outlet 14.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is explained further details
Referring to shown in Figure 1; A kind of ventilation hoods for laboratories comprises cabinet 2, is provided with air outlet 4 in the middle part at cabinet 2 tops; Be provided with air exhauster 6 at these air outlet 4 places; Special feature of the present invention is: evenly spacedly from top to bottom on the backboard 8 of cabinet and left side wall 10 and right side wall 12 be provided with a plurality of exhaust outlets 14, these a plurality of exhaust outlets 14 communicate with air outlet 4 through airduct, preferably are provided with filter screen at the exhaust outlet place; This structural design makes the pernicious gas that is positioned at bottom of cabinet bulk and middle part to discharge timely and effectively, and does not receive the influence of cabinet internal gas circulation status.
In sum, air draft effect of the present invention is better.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
