CN2338644Y - Timing valve - Google Patents

Abstract

The utility model relates to a timing valve which uses a mechanical lock timer to have the function of timing. The rotor shaft of a micromotor drives a valve knob shaft, so after the time setting is finished and the power supply is turned on, namely automatic closing the gas channel, the timing valve of closing the gas channel at correct time is formed.

Description

A kind of time switch

Generally used gas range in life, the quick and easy of it is self-evident.But present employed gas-fired boiler does not all possess timing function, so Chang Fashengyin forgets that Guan Huoer causes food by the accident burnt, that utensil burns in use.The utility model is at this deficiency, designed a kind ofly can regularly close the switch of gas channels, thereby stopped to forget the generation of closing this phenomenon of fire, brings great convenience to the user.

The utlity model has simple in structure, reliable performance, advantage such as practical, easy to use.Set forth the utility model according to diagram below.

The utility model is by micromotor [1], axle [2], cam [3] mechanical clock timer [4], contact switch [5], contact switch [6], buzzer [7], switch [8], power line [9], [10], [11], [12], [13], shell compositions such as [14] is characterized in that rotor shaft [2] one ends connect the rotation axis of gas stove switch, and the other end is connected with turn-knob, axle [2] is the rotor shaft of micromotor [1], and draws from micromotor [1] two ends.When not needing regularly, its usage mode is the same with the mode of the existing gas range that uses, and only needs the twisting turn-knob to get final product.Rotor shaft [2] by micromotor [1] drives the gas stove switch rotation axis, because power line [9] to no current between the power line [13] passes through, so micromotor [1] is driven and freely rotates by external force, the firepower size adjustment freely, when the needs timing, only need twisting mechanical clock timer [4] to get final product to setting time location, contact switch this moment [5] is switched on concavo-convex the wheel under the effect of mechanical clock timer [4], contact switch [6] is disconnected concavo-convex the wheel under the effect of mechanical clock timer [4], so power line [9] to no current between the power line [13] passes through, micromotor [1] is not driven by electric current, buzzer [7] is not named ring, the big I of firepower is regulated arbitrarily, when the time operation of setting finishes, contact switch [6] is because mechanical clock timer [4] concavo-convex taken turns effect is switched on, between contact switch [5] and the contact switch [6] is normal open, and gas range is at this moment among using, so the boss [3] on the axle [2] is in on-state with switch [8] jack-up, power line [9] has electric current to pass through between power line [13], micromotor [1] rotates under the effect of electric current, because the gas stove switch rotation axis is connected with the rotor shaft [2] of micromotor [1], so the gas stove switch rotation axis is being with towards closing the source of the gas direction and is being rotated, when going to the position that gas circuit is closed, boss [3] on the rotor shaft [2] of micromotor [1] is turned round, make switch [8] fall and be in off state, power line [12] is disconnected between power line [13], and micromotor [1] is no longer driven by electric current.When buzzer [7] finishes in the set time operation, contact switch [5] and contact switch [6] are all taken turns effect by mechanical clock timer [4] concavo-convex and are connected, buzzer this moment [7] begins to pipe, the time of reminding the user to set has been moved and has finished, pipe continue for some time after, contact switch [5] is because the recessed action of cam of mechanical clock timer [4] is disconnected, and buzzing is gone back to [7] and stopped to pipe.Reuse as need, whether no matter regularly, more than action repeats to get final product.

Claims (1)

1. time switch, be linked in sequence by micromotor, timer, cam switch etc., its row is levied and is: the rotor shaft of micromotor stretches out from the two ends of micromotor, one end of its rotor shaft is connected with the gas stove switch rotation axis, the other end connects turn-knob, a series connection connection of little electronic two power lines connects timer, another root coupled in series one switch, the cam interlock on this switch and the gas stove switch rotation axis.
