The specific embodiment
Core of the present utility model is to provide a kind of opening and closing structure of air door, and this opening and closing structure can improve the operating efficiency of blower fan effectively.Another core of the present utility model is to provide a kind of smoke exhaust ventilator that comprises the opening and closing structure of above-mentioned air door.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 1-5, in a kind of specific embodiment, the opening and closing structure of the air door that the utility model provides, comprise the first connector 3, the second connector 4, motor 5, power switch, frame 6, wherein power switch is controlled the rotating and reverse of rotating shaft of motor 5, and rotating shaft is fixedly connected with the first connector 3, the first connector 3 and the second connector 4 are hinged, the second connector 4 provides rotating torque for air door 2, and power switch, motor 5 are installed on frame 6, and air door 2 is hinged with frame 6.When the second connector 4 is fixedly connected with air door 2, the second connector 4 or the first connector 3 are provided with the rotation slot rotated for the second connector 4.Certainly, the second connector 4 also can be hinged with air door 2, and wherein the second connector 4 and the first connector 3 can be all member structure.
When needs are used smoke exhaust ventilator, by the rotating shaft forward of operating power switch drive motor 5, rotating shaft drives the first connector 3 and rotates, and the first connector 3 drives the second connector 4 and rotates, and the second connector 4 drives air door 2 and rotates, and finally realizes opening of air door 2; When needs are closed air door 2, rotating shaft reversion by operating power switch drive motor 5, rotating shaft drives the first connector 3 and rotates, the first connector 3 drives the second connector 4 and rotates, the second connector 4 drives air door 2 and rotates, finally realize closing of air door 2, wherein the rotation of the rotating shaft of motor 5 is can open air door 2 with the rotating shaft rotation to be defined as forward.
Known by foregoing description, in the opening and closing structure of the air door provided at the utility model, the final air door 2 that drives of motor 5 rotates, realize the switching of air door 2, can realize with respect to the effect that needs blower fan in background technology the situation that air door 2 is opened always, be blower fan in the course of the work total some energy consumption be that this opening and closing structure has improved the operating efficiency of blower fan effectively for opening the situation of air door 2.
Further, this opening and closing structure also comprises travel switch 1, travel switch 1 is for limiting the turned position of air door 2, wherein travel switch 1 comprises the spacing preiection 13 be positioned on air door 2 and is arranged on upload control switch 12 and the descending gauge tap 11 on frame 6, and spacing preiection 13 is between upload control switch 12 and descending gauge tap 11.When needs are opened air door 2, spacing preiection 13 moves upward, and when spacing preiection 13 touches to up gauge tap 12, the rotating shaft of motor 5 stops operating, air door 2 stop motions.When needs are closed air door 2, spacing preiection 13 moves downward, and when spacing preiection 13 touches to descending gauge tap 11, rotating shaft stops operating, air door 2 stop motions.Certainly, spacing preiection 13 also can be arranged on frame 6, and upload control switch 12 and descending gauge tap 11 all are arranged on air door 2, and certain travel switch 1 also is confined to above-mentioned a kind of, the travel switch 1 of other form please refer to prior art, and the utility model repeats no more.By travel switch 1 is set on opening and closing structure, effectively avoided air door 2 amounts of spin excessive and touch the situation of frame 6, extended the service life of air door 2.On the other hand, by travel switch 1 is installed, can effectively avoid air door 2 to turn to extreme position, and the rotating shaft of motor 5 is still being rotated, thereby damaging the situation of motor 5, improving the safety in utilization of smoke exhaust ventilator.
Preferably, the first connector 3 is rotating disk, and the shape of its turntable can be polygon, circle etc.When the first connector 3 is rotating disk, the power that rotating shaft acts on rotating disk is comparatively disperseed, and has extended the service life of the first connector 3.The preferred rotating disk of the utility model is disk, and the center of circle of disk is positioned on the bearing of trend of axis of rotating shaft, be convenient to the processing and manufacturing of rotating disk, and the power that makes rotating shaft act on rotating disk is comparatively even, has further extended the service life of rotating disk.
