Abstract
The invention relates to an exhaust fan, which mainly aims to solve the problems of inconvenient mounting of the traditional exhaust fan and formation of a gap between a mounting pipe and a wall mounting hole. The exhaust fan comprises a fan head and a mounting pipe, wherein the mounting pipe is fixedly connected to one side of the fan head; an annular air bag is arranged to cover the mounting pipe; an inflation inlet is formed on the air bag; and a plug is arranged at the inflation inlet. As the air bag is arranged outside the mounting pipe of the exhaust fan, the mounting pipe of the exhaust fan is placed in a mounting hole and fixed and then air is charged into the air bag through the inflation inlet so that the air bag dilates until the mounting hole is sealed; therefore, the gap is prevented from being formed between the exhaust fan and the wall mounting hole; and the air in the air bag only needs to be discharged when dismantling the exhaust fan; and therefore, the exhaust fan is convenient to dismantle and install.
Description
Technical field
The present invention relates to a kind of ventilating fan.
Background technique
In order to guarantee indoor well-ventilated, some building can be installed ventilating fan on wall, the situation that ventilating fan especially is installed in the toilet of factory building or house is more, when installing, ventilating fan need on wall, offer mounting hole, fixedly mount after then the mounting pipe of ventilating fan being put into mounting hole, but always there is the gap in this kind installation method between mounting pipe and the mounting hole when specific operation, cause installing insecure.If the gap is sealed with cement etc., will be very inconvenient when removing ventilating fan later on.
Summary of the invention
The object of the present invention is to provide a kind of ventilating fan, this ventilating fan can be eliminated the slit between mounting pipe and the wall mounting hole when mounted, and mounting or dismounting are convenient.
The present invention solves the technological scheme that its technical problem takes: a kind of ventilating fan, comprise fan head and mounting pipe, mounting pipe is fixedly connected on a side of fan head, it is characterized in that, the described mounting pipe outside is enclosed with the air bag of a ring-type, described air bag is provided with inflation inlet, and there is obstruction at the inflation inlet place.
The invention has the beneficial effects as follows: the mounting pipe outside is provided with air bag, with the mounting pipe of ventilating fan put into mounting hole and fixing after, inflate in air bag by inflation inlet, air bag can expand until mounting hole is sealed, avoided the slit between ventilating fan and the wall mounting hole, when removing ventilating fan the gas in the air bag emitted and get final product easy accessibility.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 fan head, 2 mounting pipe, 3 air bags, 4 inflation inlets.
Embodiment
As shown in Figure 1.A kind of ventilating fan comprises fan head 1 and mounting pipe 2, and mounting pipe 2 is fixedly connected on a side of fan head 1, and described mounting pipe 2 outsides are enclosed with the air bag 3 of a ring-type, and described air bag 3 is provided with inflation inlet 4, and there is obstruction at inflation inlet 4 places.
During use, with mounting pipe 2 put on the wall mounting hole and fixing after, inflate in air bag 3 by inflation inlet 4, air bag 3 can expand until mounting hole is sealed, avoided the slit between ventilating fan and the wall mounting hole, when removing ventilating fan the gases in the air bag 3 have been emitted and get final product easy accessibility.
