Abstract
The utility model relates to an air-bag delayed automatic cut-out switch, comprising a bottom board, an air bag, a cover plate and push buttons. The utility model is characterized in that the middle of the bottom board is provided with a gas check valve. The interior of the air bag is provided with a spring that can jack up the air bag, the top is fixed with a reed, and the bottom of one end is provided with a contact. A supporting column is arranged between the bottom board and the cover plate, the contacting and disconnecting between the reed and the contact forms a circuit switch, and a delay device is formed by controlling the period of intake of the air bag. The utility model has the advantages of simple structure, low cost, convenient installation and maintenance, power saving and long service life, suitable for the illumination of dwelling houses and corridors and places that only need short time of illumination.
Description
The utility model relates to a kind of switch, and particularly a kind of illumination time-delay is autotomyed to disconnect and closed.
Current, in illuminating lamp and similar place that needs throw light in short-term of dwelling house corridor, the general lighting switch of use can not cause bulb to be switched on for a long time from cutting off after energising, not only wastes electric energy but also reduced bulb service life.Though have at present some on-delay to autotomy to disconnect and close, as electronic circuit with Chinese patent 91221456 as described in the delay switch of gasbag-type, all higher than complexity and price, be difficult for large tracts of land and promote the use of.
The purpose of this utility model is to provide a kind of simple in structure and cheap gasbag-type time-delay to autotomy to disconnect and closes.
The purpose of this utility model is achieved in that to be provided with by taper hole, air valve plug, reed in the middle of the base plate of switch and has constituted a gas non-return valve, being provided with one in air bag can be with the spring of air bag jack-up, fixed a reed at the air bag top, an its termination power line, the other end can contact with a contact of this end below, be provided with 4 pillars between base plate and the cover plate, this switch is used the time that air bag is inflated automatically, the purpose of finishing on-delay and cutting off certainly.
The utlity model has simple in structure, characteristics such as cost is low, installation and maintenance are convenient, long service life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is a practical winding diagram of the present utility model.
With reference to Fig. 1, time-delay is autotomyed to disconnect closing and is made up of base plate 8, air bag 6, cover plate 1, button 4.Be provided with a gas non-return valve in the middle of the base plate 8, it is made up of taper hole 10, air valve plug 11, reed 12.Air bag 6 inside are provided with a spring 9, and it can by the micropore between air valve plug 11 and the taper hole 10, make gas slowly enter air bag 6 inside air bag 6 top jack-up.Air bag 6 upper fixed a reed 5, reed 5 one ends can contacts with a contact 7 of its below, the other end and the contact 7 that is fixed on the base plate 8 connect power line respectively.Air bag 6 bottom edge are sealed to be fixed on the base plate 8, thereby forms gasbag chamber, and it is communicated with the external world by air valve plug 11 control taper holes 10.Air valve plug 11 is fixed on an end of reed 12, and the other end of reed 12 is fixed on the base plate 8.Button 4 places the hole in the middle of the cover plate 1, axially aligns with air bag 6 top reeds 5 and its inner spring 9 one ends.Fixing between base plate 8 and the cover plate 1 by 4 pillars 2.A luminous indicating device 3 can be set on cover plate 1, and it is by being connected to power line again after luminous indicating lamp and resistance 13 series connection, being used for the indicator cock position, and is as shown in Figure 2 above-mentioned.
The course of action that delaying time autotomys disconnects the pass such as following is under the gassiness initial condition of gasbag chamber, when needs throw light on, press the button 4, the time air bag 6 be compressed, air under pressure in the gasbag chamber is through taper hole 10, wash air valve plug 11 open, gas is discharged from gasbag chamber, and when button 4 was depressed into a certain position, contact reed 5 and contact 7 began to connect, illumination lamp ignition, button 4 continues when pressing down, and air bag continues exhaust, when button 4 can not press down again, decontrol button 4, after this, because of the sealing of air bag and the effect of gas non-return valve, gasbag chamber is gassy immediately, can only be under the thrust of spring 9, the inflation lentamente by the gas leakage of air valve plug 11, air bag 6 is unfolded simultaneously, and end face slowly raises, when gasbag chamber is inflated to a certain degree, contact 5,7 separately, and illuminating lamp breath automatically goes out, and indicator light is bright, continue inflation and be returned to initial condition until gasbag chamber, wait for next time and using,, thereby reach the disconnected switching purposes of autotomying of delaying time because of air bag 6 inflations need certain hour.
