Abstract
The invention provides a vent pipe for a chemical experiment. The vent pipe comprises a pipe body, a base, a fan and a handbrake, wherein the pipe body comprises three parts, namely a first pipe body, a second pipe body and a third pipe body; the first pipe body and the third pipe body are connected together through the second pipe body; the base is arranged at the lower part of the third pipe body; four small holes are formed in the base; the handbrake is arranged on the third pipe body; a strobe is arranged in the third pipe body; the fan is arranged at the pipe orifice of the first pipe body. The vent pipe for the chemical experiment is simple in design, and only comprises the fan, the pipe body and the base; the four small holes formed in the base are adopted for fixedly fixing the vent pipe for the chemical experiment on an experiment bench; the handbrake is very convenient in design, so that the opening and closing of the strobe are realized only by moving the handbrake up and down; the vent pipe for the chemical experiment is in external connection with an air extracting pump, so that ventilation effect is achieved; power supply is also plugged to rotate the fan.
Description
Technical field
The present invention relates to a kind of chemical experiment ventilation duct.
Background technology
In chemical experiment, there are many experiments to operate in ventilation, still, due to the restriction of condition, so many ventilations do not supply experimenter's operation.
Summary of the invention
The technical problem to be solved in the present invention is just to provide reasonable, the easy to operate chemical laboratory ventilation duct of a kind of simplicity of design.
For addressing the above problem, the present invention adopts following technical scheme: a kind of chemical laboratory ventilation duct, comprise body, attic base, fan and rim brake, described body comprises three parts, be respectively the first body, the second body and the 3rd body, described the first body and the 3rd body link together by the second body, described attic base be arranged on the 3rd body below, on described attic base, be provided with four apertures, described rim brake is arranged on the 3rd body, in described the 3rd body, be provided with gate, described fan is arranged on the mouth of pipe place of the first body.
As preferably, described the first body and the 3rd body are hollow cylinder, and the 3rd body length is greater than the length of the first body.
As preferably, described the second body is circular-arc.
As preferably, the setting corresponding with gate of described rim brake.
As preferably, described fan is formed by the right-angled intersection of two rectangle flabellums.
As preferably, on described attic base, be provided with outlet.
The invention has the beneficial effects as follows: this chemical experiment ventilation duct simplicity of design, only by fan, body and attic base, formed, four apertures that arrange on attic base can make chemical experiment ventilation duct firmly be fixed on laboratory table, rim brake design is very convenient, switch gate only need move up and down rim brake, chemical experiment ventilation duct connects aspiration pump outward, reaches ventilation effect, also can plug in and make fan rotation.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of chemical experiment ventilation duct of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult shown in Fig. 1, a kind of chemical experiment ventilation duct, comprise body 1, attic base 2, fan 3 and rim brake 4, described body 1 comprises three parts, be respectively the first body 5, the second body 6 and the 3rd body 7, described the first body 5 and the 3rd body 7 link together by the second body 6, described attic base 2 be arranged on the 3rd body 7 below, on described attic base 2, be provided with four apertures 8, described rim brake 4 is arranged on the 3rd body 7, in described the 3rd body 7, be provided with gate (not shown), described fan 3 is arranged on the mouth of pipe place of the first body 5.
Described the first body 5 and the 3rd body 7 are hollow cylinder, and the 3rd body 7 length are greater than the length of the first body 5.Described the second body 6 is circular-arc.The setting corresponding with gate of described rim brake 4.Described fan is formed by the right-angled intersection of two rectangle flabellums.On described attic base 2, be provided with outlet (not shown).
The invention has the beneficial effects as follows: this chemical experiment ventilation duct simplicity of design, only by fan, body and attic base, formed, four apertures that arrange on attic base can make chemical experiment ventilation duct firmly be fixed on laboratory table, rim brake design is very convenient, switch gate only need move up and down rim brake, chemical experiment ventilation duct connects aspiration pump outward, reaches ventilation effect, also can plug in and make fan rotation.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
