Abstract
A blower type ventilator, which comprises a blower, a flue pipe and an oil fume hood, wherein the blower contains a fan and a blower pipe for fixing the fan and guiding the wind flow; part of the flue pipe is inserted into the blower pipe, with the rest part extending out of the blower and connected with the oil fume hood; besides, the flue pipe is provided with a flue pipe outlet; the blower pipe is provided with a blower pipe outlet, coaxially arranged inside the blower pipe. Compared with existing ventilators, the utility model manages to prevent the electric motor and the impellers from contacting the dirty gases, and has distinct advantages like: simple structure, long service and easy disassembly and cleaning. Therefore the utility model has a favorable value for popularization.
Description
The utility model relates to a kind of blowing-type smoke exhaust ventilator.
Existing oil pumper is positioned at the device of its exhausting discharge flue in the running, very easily adheres to dust and grease, and dismounting inconvenience in addition so when doing cleaning and maintenance work, both wasted time and energy, is difficult to obtain satisfied effect again.
The purpose of this utility model will provide a kind of blowing-type smoke exhaust ventilator exactly, and it can overcome the drawback that existing smoke exhaust ventilator exists effectively in the problems referred to above.
The so-called blowing-type oil pumper of the utility model comprises air blast (1), flue tube (2) and lampblack-sucking cover (3).Described air blast (1) contains the blower fan (11) that is useful on air blast, and the blast pipe (12) that is used for fixing the blower fan (11) and the guides wind flow direction; One section of described flue tube (2) is interted in above-mentioned blast pipe (12), and its another section then extends to outside the air blast (1), and is connected with described lampblack-sucking cover (3).
The device that above-mentioned blower fan (11) is made up of motor and impeller; Above-mentioned blast pipe (12) end is provided with blast pipe outlet (13), and flue tube (2) end is provided with flue tube outlet (21), and blast pipe outlet (13) is an arranged coaxial with flue tube outlet (21), and both keep at a certain distance away in blast pipe (12).
The utility model is when operate as normal, and above-mentioned air blast (1) sucks in clean air by the rotation of its inner blower fan (11), forms one air-flow to blast pipe outlet (13) motion immediately in blast pipe (12).When airflow passes flue tube outlet (21) during to this section space of blast pipe outlet (13), be subjected to the influence of spatial volume expansion and air-flow self inertia, gas in the air-flow not only can also can promote the less gas of this section space internal pressure and density to blast pipe outlet (13) motion simultaneously to blast pipe (12) central extension.So the relative negative pressure that continues has been arranged between blotter cover (3) and flue tube outlet (21), and then in blotter cover (3), flue tube (2) and air blast (1), has formed one air-flow again in order to the extraction flue dust.
Compare with existing smoke exhaust ventilator, the utility model can make its motor and impeller not contact dirty gas, has simple in structure, long-life, easily removable and washable outstanding advantage, and its popularizing application prospect is very wide.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1. air blast, 11. blower fans, 12. blast pipes, the outlet of 13. blast pipes, 2. flue tube, the outlet of 21. flue tubes, 3. lampblack-sucking cover.
