Abstract
The utility model provides a vent fan whose height is adjustable, comprising a fan shell, an impeller motor arranged in the fan shell, impellers and a ventilating cover. The utility model is characterized in that a stretching type movable ventilating channel is connected between the fan shell and the ventilating cover through a chain wheel transmission mechanism and a power source; the stretching type movable ventilating channel at least consists of two sections of sleeves which are sleeved and can slide mutually; the corresponding position at the circumference of the sleeve is provided with mutually fastened elastic fasteners; the stretching type movable ventilating channel is internally provided with a stretching sleeve driven by the chain wheel transmission mechanism and formed by at least two sections of screw threads; the lower end of the stretching sleeve is connected with the upper end of the ventilating cover.
Description
The utility model relates to a kind of improved smoke exhaust ventilator, particularly be a kind of adjustable height smoke exhaust ventilator.
The draught hood of existing commercially available household smoke exhaust ventilator all adopts and the direct fixed structure of casing, uses, cleans, keeps in repair extremely inconvenient.
In view of above reason, the purpose of this utility model is in order to provide a kind of draught hood adjustable height to regulate, use, cleaning, adjustable height smoke exhaust ventilator easy to maintenance.
The purpose of this utility model is achieved like this:
The utility model adjustable height smoke exhaust ventilator comprises casing, be loaded on the impeller motor in the casing, be subjected to the motor-operated impeller of impeller, draught hood, it is characterized in that being connected with the telescopic movable wind pumping channle that is connected with power source by chain wheel driving mechanism between casing and draught hood, the formula of shrinking activity wind pumping channle saves suit by at least two and sleeve that can slide is mutually formed, the spring secures rail to sleeper that mutual snapping is arranged on the corresponding axial location of perimeter of sleeve, have in the telescopic movable wind pumping channle to be subjected at least two of chain wheel driving mechanism drive to save the telescopic that the thread bush thread sets form, the lower end of telescopic is connected with the draught hood upper end.
Sleeve-shaped in the above-mentioned telescopic movable wind pumping channle is at least positive trihedral, can prevent the rotation of movable draught hood, makes the movable draught hood can only upper and lower lifting.
Above-mentioned sleeve be shaped as regular hexahedron.
Above-mentioned power source is the low speed rotating motor that is contained in the casing.
Above-mentioned power source is the impeller motor, and the reduction box that is connected with the impeller motor output shaft is housed in the casing, and chain wheel driving mechanism is connected with reduction gearbox output shaft by clutch.
Referring to Fig. 1-Fig. 4, power source---the motor forward and backward is passed to chain wheel driving mechanism by clutch with power, drive the nut type telescopic rotation that is connected with transmission mechanism and produce stretching motion, thereby the sleeve in the drive telescopic movable wind pumping channle stretches and makes the draught hood ascending, descending.
The utility model has adopted the telescopic movable wind pumping channle, can regulate smoke pumping power size by the lifting of draught hood, uses, cleans, keeps in repair very convenient.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
