Description
The utility model relates to a kind of ventilation fan, particularly a kind of show window type ventilation fan.
Show window type ventilation fan is a kind of traditional ventilation fan, and its fan is outer to have baffle plate or the blinds that keeps out the wind, and is used for stopping after shutting ventilation fan the air of indoor and outdoor.The unfolding mode of this baffle plate mainly is two kinds of blast or hand-pulling types, but all exist certain shortcoming, wind pressure type, its weatherstrip window leaf without any the mechanism of driving, the blast that only depends on ventilation fan self to be produced blows the window leaf open, so be not easy when wind outside window is big even can not open; Hand-pulling type is in conjunction with a transmission and locking structure, and by pulling pulling, realizing opening and closing of baffle plate, this structure exists the problem of inconvenient operation.
The purpose of this utility model is exactly influenced by outside wind pressure or the shortcoming of inconvenient operation in order to overcome the folding of present show window type ventilation fan baffle plate, provide a kind of folding freely, easy to operate electronic show window type ventilation fan.
The utility model is achieved in that
Blinds one end of keeping out the wind of ventilation fan is connected on the interlock connecting rod, return spring is installed at interlock connecting rod bottom or top, there is the platform of stretching out at the middle part of interlock connecting rod in ventilation fan, one electromagnet assembly is arranged, comprise connecing under the electromagnet core, iron core at electromagnetism iron wire bag, line bag center and connect jacking block under thimble, the thimble or do not connect jacking block, do not connect jacking block thimble or on connect thimble jacking block end frame the stretching out on the platform of interlock connecting rod, on the end on electromagnet core top postive stop baffle is housed; The baffle plate below is the power spring once, this return spring can be the compression type taper spring that can compress fully, and also available spring-piece type spring is installed on when adopting the former under the baffle plate, be about to this spring and be placed on the iron core, adopt the latter then to be installed on a side of baffle plate below; One sensitive switch is arranged below baffle plate, and when electromagnet in complete adhesive the time, postive stop baffle is also depressed sensitive switch, and its inner contact is switched, with the switching of the power supply voltage of realizing the control electromagnet.This circuit is after connecting power supply, and sensitive switch is in normally closed point, directly is civil power (220V) power supply, when electromagnet during in complete adhesive, because the effect of postive stop baffle, sensitive switch often switches to and opens, and makes circuit seal in a decompression capacitor, transfer low-voltage DC supply to, like this, can make electromagnet keep attracting state, again owing to reduced voltage, make the temperature rise of electromagnet not high, be convenient to working reliably and with long-term of electromagnet.After cutting off circuit power, electromagnet dead electricity and discharge iron core resets under the effect of the return spring below the baffle plate, and sensitive switch also reverts to normally off, and with advancing, the blinds that keeps out the wind closes under the effect of return spring.Like this, just finished the open and close of the blinds that keeps out the wind.
The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 7 is a schematic representation under the inner formation of the embodiment's 2 driving mechanisms of the present utility model "on" position.
Embodiment 1: as shown in Figure 1, the keep out the wind end of blinds (1) is connected on the interlock connecting rod (2), return spring (3) is installed at interlock connecting rod (2) bottom or top, and this return spring (3) is good with compression type spirality or taper, an electromagnet assembly (4) is arranged in interlock connecting rod (2) top.
As shown in Figure 2, there is the platform of stretching out at the middle part of interlock connecting rod (2) in ventilation fan, the electromagnet assembly comprises connecing under the electromagnet core (6), iron core at electromagnetism iron wire bag (5), line bag center connecing jacking block (8), jacking block (8) stretching out on the platform at the interlock connecting rod under thimble (7), the thimble.Thimble (7) can not connect jacking block down, directly end frame stretching out on the platform at the interlock connecting rod.
Fig. 3 shows electronic circuit schematic diagram of the present utility model.By mains-supplied, can be in input end and a small capacity capacitor C
2Be used for clutter on the filtering electrical network, also can, sensitive switch K (11) and capacitor C
1Be in parallel sensitive switch K (11) and the capacitor C of civil power by being in parallel
1In any one (sensitive switch is made voltage and is switched usefulness here, and electric capacity is made step-down usefulness, at the two ends of electric capacity and connect big one by one resistance resistance R
1, after down circuitry, the high pressure that keeps on the electric capacity is bled off, also can), and then insert the bridge heap and do rectification, by the bridge heap to the power supply of electromagnetism iron wire bag, can be at electromagnetism iron wire bag two ends respectively and piezoresistance and clamp diode make overvoltage protection and use.After energising, sensitive switch K is in normally off, the bridge heap is behind the 220V commercial power rectification, add in the electromagnetism iron wire bag, thereby generation magnetic field, iron core (6) adhesive under the effect in magnetic field, iron core (6) in the process of adhesive by being installed on thimble (7), the jacking block (8) under the iron core (6), drive interlock connecting rod (2) action, cause the blinds that keeps out the wind (1) to be opened; Meanwhile, under the effect of the postive stop baffle (9) at iron core rear portion sensitive switch K often being transferred to opens, makes power supply circuits seal in capacitor C
1, make electromagnet transfer low-voltage DC supply to, can keep adhesive, make temperature rise not high again, be convenient to electromagnet and work reliably and with long-term.After cutting off the electricity supply, the electromagnet dead electricity discharges iron core (6), resets under the effect of return spring (10), and the blinds that keeps out the wind simultaneously (1) is closed under the effect of return spring (3), like this, has promptly finished the open and close of the blinds that keeps out the wind.
Shown in Fig. 4,5, there is a postive stop baffle (9) electromagnet core (6) top, and baffle plate (9) below one side is power spring (10) once, and this return spring (10) is the spring-piece type structure, and this return spring (10) below is sensitive switch (11).Press down the folding that return spring (10) drives sensitive switch (11) by baffle plate (9).
The utility model folding freely, and is easy to use, reliably and with long-term.
