Abstract
The utility model discloses an experiment table cabinet comprising a suction device and an air curtain device, wherein the air curtain device comprises a strip-shaped air outlet and a blast device which are arranged on the upper part of the operation surface of the experiment table cabinet; and the strip-shaped air outlet is communicated with the blast device. The experiment table cabinet adopting the technical scheme has the advantages that the design that the strip-shaped air outlet and the blast device are integrated with the experiment table cabinet into a whole is adopted; the manufacturing cost is low; and an air curtain is formed on the operation surface of the experiment table cabinet so that the leakage of toxic gas or other volatile toxic substances from the experiment table cabinet is greatly reduced.
Description
Technical field
The utility model relates to a kind of laboratory equipment, particularly a kind of experiment cabinet.
Background technology
During laboratory experiment; produce toxic gas or use other volatile toxic substance through regular meeting; therefore must guarantee good ventilation; though can set up extractor fan for the experimental bench cabinet; but still there are part toxic gas or other volatile toxic substance from the experiment cabinet, to overflow, experiment operator is constituted a threat to.
The utility model content
For addressing the above problem, it is a kind of cheap that the purpose of this utility model is to provide, and can reduce the experiment cabinet that toxic gas or other volatile toxic substance overflow from the experiment cabinet significantly.
For achieving the above object, the technical solution of the utility model is: a kind of experiment cabinet, comprise extractor fan, and also be provided with air curtain apparatus, described air curtain apparatus comprises that the top of the operating surface of described experiment cabinet is provided with strip air outlet and air-blast device, and described strip air outlet and air-blast device are communicated with.
Preferably, described air-blast device comprises blast apparatus and air supply duct, and described air supply duct one end is connected with described blast apparatus, and its other end is connected with described strip air outlet.
Preferably, described blast apparatus is air blast or air conditioner.
Preferably, described experiment cabinet is at least one, and described air supply duct is provided with lateral and is communicated with the strip air outlet of described different experiments cabinet respectively.
Preferably, the operating surface of described experiment cabinet is provided with seal glass window to be opened/closed.
Preferably, described experiment cabinet also is provided with the sensor that detects described seal glass window open and-shut mode, and described sensor is connected with the described air-blast device signal of telecommunication.
Adopt the beneficial effect of the technical program to be: strip air outlet and the air-blast device design of adopting and test cabinet to integrate, cheap, operating surface at the experiment cabinet forms air curtain one, reduces toxic gas or other volatile toxic substance significantly and overflows from the experiment cabinet.

Fig. 2 is a kind of schematic diagram of testing cabinet embodiment 2 of the utility model.
Numeral and the represented corresponding component title of letter among the figure:
1. test cabinet 11. strip air outlets 12. seal glass windows 2. air supply ducts 3. blast apparatuses 4. exhausting air channels 5. air exhausters
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of experiment cabinet comprises extractor fan, also is provided with air curtain apparatus, and air curtain apparatus comprises that the top of the operating surface of testing cabinet 1 is provided with strip air outlet 11 and air-blast device, and strip air outlet 11 and air-blast device are communicated with.
State air-blast device and comprise blast apparatus 3 and air supply duct 2, air supply duct 2 one ends are connected with blast apparatus 3, and its other end is connected for 11 mouthfuls with the strip air-out.
Extractor fan comprises exhausting air channel 4 and air exhauster 5.
Operation principle is, before beginning experiment, open extractor fan and air curtain apparatus, air exhauster 5 is started working, form negative pressure in the experiment cabinet, the toxic gas that produces during experiment or other harmful substance are taken away, and the blast apparatus 3 of air curtain apparatus forms a stifled air curtain by air supply duct 2 and strip air outlet 11 at the operating surface of experiment cabinet 1, toxic gas in the experiment cabinet 1 etc. is kept off back by air curtain in the process of outwards overflowing, and has significantly reduced overflowing of harmful substance.
As shown in Figure 2, all the other are identical with embodiment 1, and difference is that experiment cabinet 1 is two, and air supply duct 2 is provided with lateral and is communicated with the strip air outlet 11 of different experiments cabinet respectively.
The operating surface of experiment cabinet 1 is provided with seal glass window 12 to be opened/closed.
Adopt the beneficial effect of the technical program to be: strip air outlet and the air-blast device design of adopting and test cabinet to integrate, cheap, operating surface at the experiment cabinet forms air curtain one, reduces toxic gas or other volatile toxic substance significantly and overflows from the experiment cabinet.
In the foregoing description, the experiment cabinet 1 quantity can be one, two, three or more.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
