Abstract
The utility model relates to a household gas stove and gas water heater equipment for bathing technology field, especially to an automatic closing switch which is provided with an electronic timer. The automatic closing switch includes a knob, a switch shaft and a switch body, rotating the knob can drive the switch shaft rotating and thereby the switch body can be controlled, the switch shaft is equipped with a force return driven disk and an electromagnetic tripping mechanism, the outer part of the electromagnetic tripping mechanism is connected with the electronic timer, the force return driven disk is buckled with the electromagnetic tripping mechanism and is provided with a force return spring, when the electronic timer runs to the predetermined time the electric energy is provided for the electromagnetic tripping mechanism, thereby the electromagnetic tripping mechanism can be detached from the force return driven disk, and the force return driven disk is driven to counter-rotating under the effect of the force return spring and drives the knob rotating to close the gas source. The utility model has simple structure and convenient application, the electronic timer and gas switch are combined well, so the utility model can solve the potential safety hazard of the existing gas switch greatly, and is beneficial to ensure people #GB001 s life and property security.
Description
Technical field:
The utility model relates to domestic gas stove and accessory and bathing gas heater equipment technical field, refers in particular to a kind of automatic off switch with electronic timer.
Background technology:
Existing stove and accessory switch does not possess the device of timing to automatically switch off source of the gas, in the time of turn-offing source of the gas, must manually turn-off.And people are in daily use, tend to forget to close fire when leaving, particularly in Baoshang, because of long, be easy to forget and close burning things which may cause a fire disaster, thereby cause various harm with the fire time, gently then burn utensil, heavy then cause gas poisoning even fire etc.On the existing shower water heater, do not have automatic gas-off device yet, be easy to have very big life security hidden danger because of drawing badly and the bathing overlong time causes anthracemia.
The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and electronic timer is combined with existing burnt gas switch, realizes the control of electronic timer to burnt gas switch, thereby closes source of the gas.
The utility model realizes that the technical scheme that its purpose adopts is: this automatic off switch comprises knob, switch shaft and Switch main body, thereby rotary knob drives switch shaft rotation control switch body, resilient dial and electromagnetic trip mechanism also are installed on switch shaft, electromagnetic trip mechanism outside has connected electronic timer, return power dial and electromagnetic trip mechanism buckle mutually, return in the power dial and be provided with return spring, when moving to the scheduled time, gives by electronic timer the power supply of electromagnetic trip mechanism, make electromagnetic trip mechanism break away from back the power dial, return the power dial and produce reverse rotation and drive knob rotary closure source of the gas because of the return spring effect.
Described time the power dial is installed on the switch shaft, and its top is provided with a latch, and pegs graft with knob, and the bottom is provided with groove, is provided with return spring in the groove.
Operation principle of the present utility model is: when opening switch, rotary knob drives back power dial rotation, and this moment, return spring produced elastic force, but because of electromagnetic trip mechanism with return the power dial mutually buckle block back the power dial, so time power dial does not temporarily turn round; Electronic timer picks up counting, and when timer moves to the scheduled time, gives the power supply of electromagnetic trip mechanism by lead, makes tripping mechanism break away from back the power dial, returns the power dial and turned round by return spring elastic force, thereby drive knob off switch body, cuts off source of the gas.
After the utility model adopts said structure, electronic timer, electromagnetic trip mechanism are reached back the power dial and burnt gas switch is well combined, reach timing automatic and close the purpose of source of the gas, prevent unnecessary loss, can prevent the generation of fire incident effectively, ensure people's the security of the lives and property.
Description of drawings:
Fig. 1 is the schematic diagram of the utility model structure.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model comprises knob 1, switch shaft 8 and Switch main body 5, and knob 1 is by projection and switch shaft 8 upper groove clampings on it, the join opening and closing of control switch body 5 of switch shaft 8 and Switch main body 5.
For realizing the timing automatic off switch, resilient dial 2 of cross-under and electromagnetic trip mechanism 4 on switch shaft 8 go back to power dial 2 tops and are provided with a latch 20, and peg graft with knob 1, and the two can be rotated together.Electromagnetic trip mechanism 4 with return power dial 2 buckle mutually, and electromagnetic trip mechanism 4 connects by lead 7 and outside electronic timer 6.
In the utility model when work,, rotary knob 1 drives back 2 rotations of power dial, and this moment, return spring 3 produced elastic force, but because of electromagnetic trip mechanism 4 and time power dial 2 mutually buckle block back power dial 2, so time power dial 2 does not temporarily turn round; Electronic timer 6 picks up counting, and when timer 6 moves to the scheduled time, gives electromagnetic trip mechanism 4 power supplies by lead 7, make tripping mechanism 4 break away from back power dial 2, return power dial 2 and turned round by return spring 3 elastic force, thereby drive knob 1 off switch body 5, cut off source of the gas.
In sum, the utility model is simple in structure, and it is convenient to use, and electronic timer and burnt gas switch are made up well, has greatly solved the potential safety hazard of existing burnt gas switch, helps ensureing people's security of the lives and property.
Claims (2)
1. automatic off switch of gas furnace electronic timing, comprise knob, switch shaft and Switch main body, thereby rotary knob drives switch shaft rotation control switch body, it is characterized in that: resilient dial and electromagnetic trip mechanism also are installed on switch shaft, electromagnetic trip mechanism outside has connected electronic timer, return power dial and electromagnetic trip mechanism buckle mutually, return in the power dial and be provided with return spring, when moving to the scheduled time, gives by electronic timer the power supply of electromagnetic trip mechanism, make electromagnetic trip mechanism break away from back the power dial, return the power dial and produce reverse rotation and drive knob rotary closure source of the gas because of the return spring effect.
