Description
Technical field
This utility model relates to a kind of chemical experiment teaching aid, specifically a kind of chemical laboratory ventilation duct.
Background technology
In chemical experiment, many experiments are had to need to operate in ventilation, but due to the restriction of condition, it does not have so many ventilations are for experimenter's operation; Some existing draft tube aeration speed are uncontrollable, and control to get up to be inconvenient for.
Utility model content
The purpose of this utility model is in that to provide a kind of chemical laboratory ventilation duct, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of chemical laboratory ventilation duct, including base, body and ventilation unit; Described base vertical view is circular, and circle is formed around four installing holes; Described base top is provided with fresh air inlet, and bottom is provided with exhaust vent; Described body includes the first body, the second body, the 3rd body, switch and funnel, 3rd body is connected on base, and switch is connected on the 3rd body, and the second body is connected on switch, first body is connected on the second body, and funnel is connected on the first body; Described first body and the second body are vertical bar shaped cylindrical duct, and the second body is arc-shaped cylindrical duct, and filler neck part is connected on the first body; Described ventilation unit includes flabellum, motor and motor controller, and flabellum is connected on motor reel, and motor is connected to motor controller; Described motor controller includes hand switch and infrared receiver and infrared remote controller, and infrared receiver accepts the signal control motor speed that infrared remote controller sends.
As further program of the utility model: described exhaust vent and air inlet are circle, and the radius of air outlet is more than the radius of air inlet.
As further program of the utility model: described flabellum is formed by two panels rectangle flabellum decussation, and flabellum is positioned at by inner wall of hopper.
As this utility model further scheme: in this chemical laboratory ventilation duct, all junctions are and are tightly connected.
Compared with prior art, the beneficial effects of the utility model are:
This utility model simple in construction, easy to use; This chemical laboratory ventilation duct drives flabellum to rotate by motor and produces wind, can pass through to control motor speed and control ventilation speed; Motor is connected to infrared remote controller, it may be achieved remote pilot ventilation speed; This chemical laboratory ventilation duct adjustable ventilation speed, improves teaching condition, improves quality of instruction.
