Utility model content
The purpose of this utility model is to provide a kind of extractor fan, uses human body after existing extractor fan still can suck the problem of more excitant or harmful gases to solve.
The utility model is achieved in that
A kind of extractor fan, comprise air exhauster and pipe, described pipe connects described air exhauster, it is characterized in that, described extractor fan also comprises at least one blast pipe and joint, the mouth of pipe at described blast pipe two ends is respectively air inlet and air outlet, and described air outlet is by pipe described in described fittings, and described air inlet is provided with flase floor.
Further, described blast pipe is semiellipse pipe, and described joint is that semiellipse turns circular joint.Semiellipse pipe is applicable to blast pipe and is exposed to outside body of wall, and when blast pipe is installed in metope.
Further, described blast pipe is sector tube, and described joint is fan-shapedly turn circular joint.Sector tube is applicable to blast pipe and is exposed to outside body of wall, and when blast pipe is installed in foundation.
Further, described blast pipe is triangle tube, and described joint is that triangle turns circular joint.Triangle tube is applicable to blast pipe and is exposed to outside body of wall, and when blast pipe is installed in foundation.
Further, described blast pipe is rectangular tube, and described joint is squarely turn circular joint.Rectangular tube can be selected when blast pipe is embedded in body of wall.
Further, described blast pipe is round tube.Round tube can be selected when blast pipe is embedded in body of wall.
The beneficial effect that the utility model realizes:
When using this extractor fan, the gas being arranged so that indoor irritative gas or being detrimental to health of blast pipe, under the effect of air exhauster, enter blast pipe and discharge outdoor, avoid flow for a long time in the room air human body soakage that causes of irritative gas or the gas that is detrimental to health more, greatly reduce human body excitant or harmful gases soakage.According to the size in room and actual needs, at least one blast pipe can be set, to shorten time of gas of extracting irritative gas out or being detrimental to health.Flase floor can prevent the animals such as mouse from entering blast pipe.

Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 a shows the mounting structure of semiellipse pipe, Fig. 1 b shows the cross-sectional structure of semiellipse pipe, Fig. 2 a shows the mounting structure of sector tube, Fig. 2 b shows the cross-sectional structure of sector tube, Fig. 3 a shows the mounting structure of triangle tube, and Fig. 3 b shows the cross-sectional structure of triangle tube, and Fig. 4 shows the mounting structure of rectangular tube, Fig. 5 shows the mounting structure of round tube, and Fig. 6 shows the connectivity structure of blast pipe and pipe.Consult Fig. 1 a to Fig. 6, extractor fan comprises air exhauster and pipe 105, pipe 105 connects air exhauster, extractor fan is bag blast pipe 103 also, blast pipe 103 can select semiellipse pipe 1031, sector tube 1032, triangle tube 1033, rectangular tube 1034 or round tube 1035 according to the position difference of installing, and blast pipe 103 is communicated with pipe 105.
According to the size in room and actual needs, blast pipe 103 can arrange at least one, to shorten time of gas of extracting irritative gas out or being detrimental to health.
Blast pipe 103 can be set to different shapes as required.When blast pipe 103 is exposed when body of wall is outer, if blast pipe 103 is arranged on metope 101, then blast pipe 103 is semiellipse pipe 1031, and namely the cross section of blast pipe 103 is half elliptic; If blast pipe 103 is arranged on foundation, then blast pipe 103 is sector tube 1032 or triangle tube 1033, and namely the cross section of blast pipe 103 is fan-shaped or triangle.According to the angle design in corner, two tube walls of sector tube 1032 or triangle tube 1033 and two metopes in corner fit.Common, the central angle of sector tube 1032 is 90 degree, and the cross section of triangle tube 1033 is right angled triangle.As required, blast pipe 103 can be embedded in body of wall.
When blast pipe 103 is embedded in body of wall, blast pipe 103 can select round tube 1035 or rectangular tube 1034.Rectangular tube 1034 is communicated with pipe by the square circular joint that turns.
Blast pipe 103 is communicated with pipe 105 by joint 104, and joint 104 can adopt semiellipse to turn circular joint accordingly according to the blast pipe 103 selected dissimilar, fan-shapedly turns circular joint, triangle turns circular joint, squarely turn circular joint and circular joint.
The mouth of pipe at blast pipe 103 two ends is respectively air inlet and air outlet, during installation, the air outlet of blast pipe 103 by fittings pipe, the air inlet of blast pipe 103 overhead 102 distance be 5cm-15cm, according to test checking, exhausting best results when distance is 10cm.According to the actual requirements, the air inlet that also can change blast pipe 103 overhead 102 distance.Air inlet is provided with Turbogrid plates, enters blast pipe 103 to prevent the animals such as mouse.
When blast pipe 103 is embedded in body of wall, the round tube 1035 selected or the air inlet of rectangular tube 1034 pass surface of wall in body of wall, and opening is downward-sloping toward body of wall in body of wall.The air inlet tilted can discharge the ponding in blast pipe 103.
Double elliptical tube, sector tube or triangle tube can increase colored drawing pattern and suspension member button, while increase aesthetic, increase using function.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
