Description
The utility model relates to a kind of shutter type vetilation fan, particularly a kind of electric shutter type vetilation fan.
Shutter type vetilation fan is a kind of traditional ventilation fan, and the unfolding mode of its window leaf mainly is two kinds of wind pressure type and hand pulling types, also has plenty of the electromagnet extending type, but all exists certain shortcoming.Wind pressure type, its window leaf without any driving mechanism, depend the blast that ventilation fan self produced alone the window leaf blown open, so, when outdoor wind is big, be not easy even can not open; Hand pulling type is to have added a transmission and locking mechanism on the basis of blast, by manually draw back the window leaf, locking mechanism makes it be locked in opening, though overcome the former shortcoming like this, but still exists the problem of inconvenient operation; And the electromagnet extending type, be to adopt electromagnet and transmission mechanism to be used, electromagnetic actuation after energising, just though realized semi-automation like this, also there is the unreliable and big problem of noise of work to window Ye Lakai in this power of leaning on adhesive.
The purpose of this utility model is exactly in order to overcome the above-mentioned shortcoming of present shutter type vetilation fan, and a kind of semi-automation, reliable operation, electric shutter type vetilation fan that noise is little are provided.
The utility model is to realize like this.
The utility model adopts the spur rack permagnetic synchronous motor to do the mechanism of control shutter motion.Comprising synchronous motor, spur rack, microswitch, circuit control section and transmission mechanism part, transmission mechanism partly comprises travelling gear and comprises the jaw clutch of upper armature, electromagnetism iron wire bag, lower armature, clutch gear structure, the motion of shutter is finally controlled in the running of circuit control section control synchronous motor and the motion of transmission mechanism part.Spur rack directly or by other object is connected with shutter, directly connects the interlock connecting rod that louvered window leaf or connection have connected the louvered window leaf as spur rack.
The structure of spur rack permagnetic synchronous motor is: establish a synchronous motor at the rear of ventilation fan motor, connect jaw clutch behind the synchronous motor, the formation of jaw clutch is docile and obedient preface and is comprised upper armature, electromagnetism iron wire bag, lower armature, the clutch gear structure, upper armature is the laminated structure that central lower has a cylinder, the electromagnetism iron wire is paperwrapped on the hollow cylinder skeleton, lower armature is the hollow tubular structure of bottom center, electromagnetism iron wire bag center drum and lower armature emptying aperture are on same axis, clutch gear is by last slice clutch gear, spring, following sheet clutch gear is formed, on the clutch gear, be spring between following sheet clutch gear, behind the holddown spring, on, following sheet clutch gear engaging, there is cylinder last slice clutch gear central upper portion position, passes the lower armature emptying aperture, and is relative with the cylinder of upper armature below.The gear of following sheet clutch gear and the rotor engaged of synchronous motor, last slice clutch gear is meshed with a travelling gear; And and then mesh by this travelling gear and next travelling gear, have one to four travelling gear, last travelling gear is meshed with the tooth of spur rack side, the structure of spur rack is that a side has tooth, and its another side has recessed stopper slot, in the corresponding position of spacing groove face, microswitch is installed on the wiring board of circuit control section or on casing, when spur rack moves to the stopper slot place, microswitch disconnects, and synchronous motor quits work.
Jaw clutch also can adopt other structure, but the rotor engaged of a slice clutch gear and synchronous motor wherein, other has a slice clutch gear to be meshed with travelling gear.
The electromagnet casing that plastics can be arranged between the lower armature of jaw clutch and clutch gear in addition.
Can connect louvered window leaf and ventilation fan housing by resilient spring, take this to help the window leaf and reset.
Circuit theory can adopt the utmost point at alternating current to connect two electric capacity that are in parallel, series connection microswitch before or after the electric capacity wherein, these electric capacity two ends are synchronous motor in parallel simultaneously, connect bridge heap rectification circuit behind two shunt capacitances, bridge heap rectification circuit two ends connect the electromagnet of jaw clutch, and electromagnetic field is provided.Provide alternating voltage by microswitch, electromagnetism iron wire bag, bridge heap for synchronous motor, synchronous motor energising running, electromagnet energising adhesive, make transmission mechanism the downward adhesive of upper armature, press down the cylinder on last slice clutch gear top of clutch gear, make upper and lower clutch gear engaging, the power that this moment, synchronous motor produced orders about the spur rack action just by clutch gear, travelling gear, shutter is opened in the action of drive shutter.When spur rack runs to a certain degree, the stopper slot that is spur rack is at the microswitch place, stopper slot on the spur rack acts on mutually with microswitch, microswitch disconnects, cause synchronous motor to stop action, and electromagnet also keeps operating on low voltage, and clutch gear is kept engagement state, and this moment, the window leaf still stayed open state.After cutting off the complete machine power supply, electromagnet dead electricity and discharging, clutch gear separates, and the louvered window leaf is closed because of self the gravity and the effect of return spring, has finished the closure of louvered window leaf.
Thereby the utlity model has semi-automation, reliable operation, advantage that noise is little.
The utility model is described in further detail below in conjunction with drawings and Examples.
