Bathhouse is now all that rotation blade is suspended in the ventilated port of bathhouse, indoor air directly contacts with outside air, cause the heat in bathhouse to outflow in a large number, temperature in bathhouse reduces rapidly, and for the people who has a bath, the acute variation of temperature easily causes the relevant diseases such as flu.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of ventilating fan, its object: prevent that indoor air from directly contacting with outside air.
For achieving the above object, the technical solution of the utility model is as follows:
A ventilating fan, comprises frame, and frame is provided with flange and ventilated port, and flange is provided with attachment hole, and ventilating fan is arranged in ventilated port, and ventilating fan comprises fore shell, rotation blade and ventilation duct, and rotation blade is arranged in fore shell, and fore shell is fixedly connected with ventilation duct;
In frame, be also provided with air bag and isolating plate mechanism;
Air bag is arranged on the sidewall of frame, and air bag is provided with gas charging valve;
Isolating plate mechanism comprises isolating plate, screw mandrel, driving mechanism and motor, isolating plate is arranged in the flange side of frame, screw mandrel rotates and is installed in frame, isolating plate is provided with and the corresponding slide block of screw mandrel, driving mechanism is connected with one end of screw mandrel, and the other end of driving mechanism is axially connected with motor.
Preferably, the area of the maximum side of isolating plate is greater than the cross-section area of ventilated port.
Preferably, fore shell is fixed in ventilated port.
Preferably, the cross-section area of the suction port of ventilation duct is greater than the cross-section area of air outlet.
Preferably, the surface of isolating plate is provided with antioxidation coating.
By technique scheme, when ventilating fan does not move, isolating plate keeps off on ventilated port, has prevented that indoor air from directly contacting with outside air; When ventilating fan moves, isolating plate is opened, and takes a breath, and utilizes the structure of ventilation duct self, has prevented that external cool air from entering into suddenly in a large number indoor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment 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 embodiments more of the present utility model, 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 structural representation of a kind of ventilating fan disclosed in the utility model.
