Abstract
The utility model relates to an air exhausting fan which comprises a housing, a motor, blades, a window leaves, a window leaf interlocking rod, and particular a draw rod and a driving mechanism. The upper end of the draw rod is connected with the window leaf interlocking rod through a small shaft, the lower end of the draw rod is connected with the cam of the driving mechanism through a small shaft, and the driving mechanism is composed of a motor, a speed reducer, a cam and a travel switch. The utility model has the advantages of simple structure, low cost, and flexible open and close of the window leaves and overcomes the phenomenon that stuck by greasy dirt, the window leaves can not be opened.
Description
The utility model relates to a kind of ventilating fan.
At present, ventilating fan is widely used in meeting room, room and kitchen, to improve indoor environmental condition.The window leaf of ventilating fan all is follow-up-type basically, and when the ventilating fan of this structure was used for the kitchen, after use a period of time, the window leaf can be clung by greasy dirt, and does not open, and not only influences using effect, and makes troubles to the user.
The purpose of this utility model is at above-mentioned shortcoming of the prior art, and a kind of ventilating fan that is driven active window leaf unlatching, closure by driving mechanism is provided.
The purpose of this utility model is to realize like this, a kind of ventilating fan, it includes housing, motor, fan blade, window leaf and window leaf linkage rod, the window leaf is fixed on the housing by the rotating shaft of its both sides, the bottom, upper end of window leaf is fixed on the window leaf linkage rod by little axle, the top of window leaf snaps in the gap of window leaf linkage rod, it is characterized in that it also includes pull bar and driving mechanism, the upper end of pull bar links with window leaf linkage rod by little axle, and the lower end of pull bar links by the cam of little axle with driving mechanism.
The utility model has the advantages that simple in structurely, cost is low, and the window leaf opens and closes flexibly, has overcome greasy dirt with the sticking phenomenon of extremely not opening of window leaf.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a driving mechanism principle sketch of the present utility model.
As shown in Figure 1, the utility model includes housing (1), motor (4), fan blade (2), window leaf (3) and window leaf linkage rod (5), the window leaf is fixed on the housing by the rotating shaft of its both sides, the bottom, upper end of window leaf is fixed on the window leaf linkage rod (5) by little axle, the top of window leaf snaps in the gap of window leaf linkage rod, it is characterized in that it also includes pull bar (6) and driving mechanism, the upper end of pull bar (6) links with window leaf linkage rod (5) by little axle, and the lower end of pull bar (6) links by the cam of little axle with driving mechanism.
Driving mechanism is made up of motor (7), speed reducer (9), cam (8) and position limit switch (10), speed reducer is made up of worm screw (11), worm gear (12), driving gear (13), driven gear (14), worm screw (11) is contained in the rotating shaft of motor (7), worm gear (12) is meshed with worm screw (11), driving gear (13) is coaxial with worm gear (12), driven gear (14) is coaxial with cam (8), and position limit switch (10) is contained in the below of cam (8).
Working procedure of the present utility model following (referring to Fig. 2):
When electrical machinery of ventilator (4) is worked, the motor of driving mechanism (7) is also worked, motor (7) drives cam by speed reducer and clockwise rotates, cam pulls down the active window leaf linkage rod by pull bar, the window leaf is opened, when window leaf during near horizontal position, the projection on the cam touches position limit switch and turns off motor (7) power supply, and the window leaf is in full-gear.
When exhaust fan stop working, motor (7) drives cam by speed reducer and continues former direction rotation, and pull bar upwards pushes away the active window leaf linkage rod, thereby it is dead that the window leaf is closed, and at this moment, the projection on the cam touches position limit switch, turns off the power supply of motor (7).
Claims (2)
1, a kind of ventilating fan, it includes housing (1), motor (4), fan blade (2), window leaf (3) and window leaf linkage rod (5), the window leaf is fixed on the housing by the rotating shaft of its both sides, the bottom, upper end of window leaf is fixed on the window leaf linkage rod (5) by little axle, the top of window leaf snaps in the gap of window leaf linkage rod, it is characterized in that it also includes pull bar (6) and driving mechanism, the upper end of pull bar (6) links with window leaf linkage rod (5) by little axle, and the lower end of pull bar (6) links by the cam of little axle with driving mechanism.
2, ventilating fan according to claim 1, it is characterized in that driving mechanism is made up of motor (7), speed reducer (9), cam (8) and position limit switch (10), speed reducer is made up of worm screw (11), worm gear (12), driving gear (13), driven gear (14), worm screw (11) is contained in the rotating shaft of motor (7), worm gear (12) is meshed with worm screw (11), driving gear (13) is coaxial with worm gear (12), driven gear (14) is coaxial with cam (8), and position limit switch (10) is contained in the below of cam (8).
