Description
Technical field
The present invention relates to the safety-type vent cabinets of experimental instrument field more particularly to a kind of easy cleaning.
Background technique
It is easy to that chemical substance and organism and particle (smog, coal smoke, dust can be generated during chemical experiment
And aerosol), if by that these substances cannot be excluded laboratory as soon as possible shadow will be caused to the body of experiment operator
It rings, therefore, air exhausting device can be all had in existing vent cabinet, the exhaust gas of generation is quickly discharged, but there is disadvantage:
(1) exhaust gas can directly be contacted with vent cabinet inner wall during air draft, and some of dust residues are in vent cabinet inner wall, another part
Chemical gas and vent cabinet Long Term Contact can generate corrosion to vent cabinet, and existing vent cabinet very takes inner wall cleaning up
Power, and once there is corrosion condition, integral replacing is carried out to vent cabinet inner wall；(2) sliding window of most vent cabinet
Manual switch is all used, but when experimenter is busy, generally requires could open vent cabinet after putting down experiment equipment, is operated not
It is convenient also dangerous.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of safety-type vent cabinets of easy cleaning, convenient for experimenter to ventilation
Cabinet is cleaned, and realizes the automation folding of sliding window, Environmental Safety.
The present invention is achieved by the following technical solutions: a kind of safety-type vent cabinet of easy cleaning, including vent cabinet sheet
Body and the exhaust fan that vent cabinet body exterior is arranged in, the vent cabinet ontology include lower cabinet body and are arranged in above lower cabinet body
Upper cabinet body, the upper cabinet body bottom are equipped with experiment table top, and the upper cabinet body front panel is equipped with sliding window and display controller,
The sliding window is equipped with form driving device and human body displacement sensor, and the human body displacement sensor setting is regarded in sliding
The top position of window, the upper cabinet body inner top are equipped with hood and exhaust duct, and the hood is the hollow of bottom opening
The hollow circuit cylinder of rotary table and both ends open is composed, and the base diameter of the hollow round table is identical with the diameter of hollow circuit cylinder,
And hollow round table bottom is connected with the open end of hollow circuit cylinder, the side plate inner wall of the hollow circuit cylinder and upper cabinet body fits closely,
It is fixedly connected by bolt with the side plate inner wall of upper sales counter, the top of exhaust pipe one end connection hood, the other end connects
Exhaust fan is led to, the form driving device, human body displacement sensor and display controller are electrically connected.
As an improvement of the present invention, the exhaust fan air outlet is equipped with air cleaning unit.
As an improvement of the present invention, the upper cabinet body front panel is equipped with multiple sockets.
As an improvement of the present invention, be coated on the hollow round table of the hood and hollow circuit cylinder inner sidewall one layer it is anti-
Acid and alkali corrosion coating.
Compared with prior art, the invention has the benefit that
(1) by the way that hood is arranged at the top of upper cabinet body, the exhaust gas for generating experiment is directly contacted with hood, utilizes exhaust fan
Exhaust gas is quickly pumped into hood, exhaust gas is reduced and directly contacts vent cabinet inner wall, since hood and upper cabinet body side plate are logical
It crosses bolt to be fixedly connected, when there is dust accretions excessive or corrosion phenomenon, it is only necessary to unload hood, it is easy to clean and more
It changes；
(2) whether have experimenter vent cabinet in front of, issue and feel to display controller if being incuded using human body displacement sensor
Induction signal, then the folding of sliding window is controlled by controlling form driving device, realize the automation of sliding window folding, no
Only be conducive to operate, and operator is effectively avoided to forget that closing sliding window bring experimental gas leaks, and ensures behaviour
Make the safety of personnel.

Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As described in Fig. 1, the safety-type vent cabinet of a kind of easy cleaning, including vent cabinet ontology and setting are in vent cabinet ontology
External exhaust fan 1, the vent cabinet ontology include lower cabinet body 2 and the upper cabinet body 3 that is arranged in above lower cabinet body, the upper cabinet body
3 bottoms are equipped with experiment table top 5, and 3 front panel of upper cabinet body is equipped with sliding window 6 and display controller 7, the sliding window
6 are equipped with form driving device 8 and human body displacement sensor 9, and the upper of sliding window 6 is arranged in the human body displacement sensor 9
Orientation is set, and 2 inner top of upper cabinet body is equipped with hood 10 and exhaust duct 11, and the hood 10 is the hollow of bottom opening
