Abstract
The invention discloses a pipeline exhaust fan. The pipeline exhaust fan comprises a fan disc, wherein a set of positioning grooves are evenly formed in the edge of the fan disc, a fan vane is movably connected inside each positioning groove and is connected with the corresponding positioning groove through a spring, the positioning grooves are distributed in a central symmetry mode with the circle center of the fan disc as the center, and the fan vanes are made of polyvinyl chloride plastics. The fan vanes of the pipeline exhaust fan are movably connected with the fan disc through the springs and can elastically deform when subjected to powerful external force, and therefore the fan vanes and a motor are prevented from being damaged.
Description
Technical field
The present invention relates to a kind of fan, or rather, is a kind of row of conduits fan.
Background technique
For preventing that the harmful gas that equipment produces in process of production from polluting manufacturing shop, often see through exhaust duct gas discharging is applicable to the place of discharging to other.In exhaust duct, tend to arrange a fan accelerate gas in pipelines flow.
When in pipeline because external air blast reverse flow, or run in the situation of line clogging, fan covering of the fan can be out of shape breakage because being subject to powerful pressure, even therefore damages motor.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provides a kind of flabellum, in the time being subject to powerful external force, elastically-deformable ventilating fan can occur.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of row of conduits fan, comprises a fan dish, and the edge of described fan dish is provided with one group of locating slot equably, the flabellum that is movably connected respectively in described locating slot, and described flabellum is connected by spring with described locating slot.
As preferred embodiment of the present invention, the distribution that is centrosymmetric centered by the center of circle of described fan dish of described locating slot.
As preferred embodiment of the present invention, described flabellum is made up of igelite.
Because row of conduits electric fan of the present invention is flexibly connected by spring with fan dish, in the time that covering of the fan is subject to strong External Force Acting, can there is elastic strain in flabellum, thereby avoid the damage of flabellum and motor.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological 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 perspective view of row of conduits fan of the present invention;
Fig. 2 is the row of conduits fan perspective exploded view in Fig. 1.
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.
The invention provides a kind of flabellum, in the time being subject to powerful external force, elastically-deformable ventilating fan can occur.
As shown in Figure 1 and Figure 2, a kind of row of conduits fan 1, comprises a fan dish 2, and the edge of described fan dish 2 is provided with one group of locating slot 31 equably, described 31 li of flabellums 32 that are movably connected respectively of locating slot, described flabellum 32 is connected by spring with described locating slot 31.
As shown in Figure 1 and Figure 2, described locating slot 31 distribution that is centrosymmetric centered by the center of circle of described fan dish 2.
This row of conduits fan, described flabellum 32 is made up of igelite.
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.
Claims (3)
1. a row of conduits fan (1), comprise a fan dish (2), it is characterized in that, the edge of described fan dish (2) is provided with one group of locating slot (31) equably, the inner flabellum (32) that is movably connected respectively of described locating slot (31), described flabellum (32) is connected by spring with described locating slot (31).
2. row of conduits fan according to claim 1, is characterized in that, the distribution that is centrosymmetric centered by the center of circle of described fan dish (2) of described locating slot (31).
