Abstract

The automatic controllable timer is composed of a power supply mechanism driven by an alarm clock, and two stop power supply mechanisms. The power supply mechanism moves the enlargement of the alarm setting surface axle sleeve notch, and the enlargement of the alarm setting spring up and down to switch off the contact type power supply switch. The timing wheel of the second stop power supply mechanism is driven by the hour wheel. The projection on the timing wheel controls the switch of the normally closed lever spring to switch on and switch off. The control range had better is within 0 to 4 hours. When the number of teeth of the alarm wheel and the timing wheel is enlarged by 100%, the control range can be enlarged to 0 to 12 hours, can vary without step, and can be selected arbitrarily. The utility model is capable of time counting and controlling two or more than two household appliances. One automatic controllable timer has multiple purposes.

Description

Automatic controllable timer

The utility model is a kind of automatic controlled timer that is driven by alarm clock, can with the supporting use of various household electrical appliance.

Existing timer can only stop automatically and can not start automatically, maybe can only select the time of power supply beginning and can not stop power supply automatically.

The purpose of this utility model is to provide a kind of power supply and power failure that comes control apparatus equipment by existing alarm clock mechanism, can control the domestic electric appliance running more than two or two again simultaneously, and select arbitrarily the duration of runs in 0-4 hour scope.

The utility model is to realize like this.Administration of power supply is the alarm spring increasing with former alarm clock, alarm spring rises when rise making a noise, make the contact type power switch closed and power, the mechanism that stops power supply has two kinds, first kind is to utilize alarm clock that the size of the over glaze cover breach that makes a noise is controlled, when alarm clock runs to the selected time, alarm spring descends and the contact type power switch is opened and stops power supply.Time range preferably was controlled within 0-4 hour.Second kind is to drive timing wheel by hour wheel by connection gear to control normally closed lever spring switch by the boss on the timing wheel and open and stop power supply.The scope of control can steplessly change in 0-4 hour, selected arbitrarily, if with oppposite alarming wheel, the expansion of the number of teeth of timing wheel is twice, and scale changes 0-24 hour into, and suitable change then can make the time range of control expand to 0-12 hour to the over glaze cover breach that makes a noise.Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

The administration of power supply (see figure 1) is that a contact type power switch (1) is suitably installed in the top of the alarm spring (3) at former alarm clock, contact is connected with relevant socket respectively, (the circuit catenation principle is seen Fig. 2), on the contact insulation top (2) is being housed down, when alarm clock is gone to predetermined power-on time (being that alarm clock is opened the noisy time), alarm spring (3) rises, top (2) rising that promotes to insulate makes junction closure and powers, power failure mechanism has two kinds, first kind of structure is to utilize the size of the over glaze cover breach (5) that makes a noise is controlled, when alarm clock is covered noisy over glaze cover breach (5), alarm spring (3) descends, and insulation top (2) loses supporting and switch is opened and cuts off the electricity supply; Second kind of structure is to connect to come out a connection gear (8) by hour wheel (7), drive timing wheel (11) (this takes turns size specification and oppposite alarming wheel (6) is identical) by (8), an insulcrete (16) is housed on the timing wheel (11), one arc cam (12) (its length be circular arc 2/3rds) is housed (16), 25～inclination of 50 degrees degree is made at the boss two ends, between timing wheel (11) and the insulcrete (16) a cruciform clamp reed (15) is arranged, under have copper sheathing (25) be fastened on the axle (13) on, on copper sheathing (17) wringing fit is arranged, turning axle (13), motionless and the insulcrete (16) of timing wheel (11) is rotatable, so that regulate the length of power-on time, at the other normally closed lever spring switch (14) that is equipped with of timing wheel (11), this switch is made of skeleton (19) that is connected as a single entity with upper contact (20) and the following contact (21) that has lever (22), lever (22) rotates around axle (23), for maintained switch normally closed, be equipped with spring (18) up and down contact make by electric conductor, be connected with socket respectively, lever (22), skeleton (19) is insulator, lever (22) extends in the scope of boss (12), when boss (12) rotates to lever (22) below, contact can be backed down and stops power supply.This cover changes arbitrarily within 0～4 hour for the range of control of power failure mechanism, the axle (9) of this cover mechanism and axle (13) are gone up boring in the main frame plate (27) of alarm clock, support with brass support (10), as required, the contact type power switch can be adorned two, and timing wheel (11) and normally closed lever spring switch can be adorned bilayer.(see figure 3) is equipped with three sockets on the utility model bonnet, a power input socket (28), two accessory power outlets (29) and (30), timing wheel index dial (31) and knob (32) are housed, and the noisy spoon (33) of opening of former alarm clock, end the device (34) that makes a noise, make a noise to spoon (35), leave spoon (36), walk spoon (37).

Using method of the present utility model is simple: selected power supply time started and determined that the time of making a noise is identical, select the length of electric power feeding time need only adjusting timing wheel knob to time-division of alarm clock at that time count to need to stop power supply the time mark the time interval.

As from the foregoing, the utility model is compared with existing timer, has following advantage:

1, the utility model is to utilize alarm clock regularly, and the element of increase is few, saves cost, both Timings, and may command household electrical appliance again, a tractor serves several purposes, easy to use.

2, supply line of the present utility model does not directly contact with the alarm clock rotatable parts, is applicable to powerful electrical equipment, and is safe and reliable.

3, the utility model can be controlled the time that electric equipment more than two or two moves different length simultaneously, controls flexible.

Accuracy when 4, the utility model does not influence.
