Abstract
The utility model relates to the technical field of the home gas-fired boiler and the scouring bath gas-fired water heater device, in particular to an automatic closing switch with a mechanical timer. The automatic closing switch comprises a knob, a switch shaft and a switch body, wherein the rotating knob carries the switch shaft to rotate in order to control the switch body, the switch shaft is further arranged with a turning power drive plate provided with a turning power spring, a tripping device and a mechanical timer, the tripping device is controlled to release the turning power drive plate by running the mechanical timer, the turning power drive plate produces reversing rotation and carries the knob to rotate and close the air supply with the function of the turning power spring. The utility model has simple structure and convenient application, the mechanical timer is perfectly assembled with the gas-fired switch, thereby largely solving the potential safety hazard of the prior gas-fired switch, and being benefit for the protection of the life fortune safety of human being.
Description
Technical field:
The utility model relates to domestic gas stove and accessory and bathing gas water-heater equipment technical field, refers in particular to a kind of automatic off switch with mechanical timer.
Background technique:
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 tend to take place forgotten when the people leaves close fire in daily use, 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 safety hidden danger because of drawing badly and the bathing overlong time causes carbon monoxide poisoning.
The model utility content:
The purpose of this utility model is to overcome the above-mentioned deficiency of existing product, and mechanical timer is combined with existing burnt gas switch, realizes the control of mechanical timer to burnt gas switch, thereby closes source of the gas.
The utility model realizes that the technological scheme that its purpose adopts is: this automatic off switch comprises knob, switch axle and Switch main body, thereby rotary knob drives switch axle rotation control switch body, resilient dial, tripping mechanism and mechanical timer also are installed on switch axle, return in the power dial and be provided with return spring, break away from back the power dial by mechanical timer operation control tripping mechanism, return the power dial and produce counterrotating and drive knob rotary closure source of the gas because of the return spring effect.
Described mechanical timer has shell and hollow shaft, and is connected to switch axle, and the mechanical timer shell is to being provided with reduction gear and energy storage wind spring between the hollow shaft.
Described time the power dial is provided with a latch, and itself and knob are pegged graft.
Working principle of the present utility model is: when opening switch, rotary knob drives back the rotation of power dial, this moment, return spring produced elastic force, but because of tripping mechanism with return the power dial mutually buckle block back the power dial, so returning the power dial does not temporarily turn round, mechanical timer picks up counting simultaneously, the length of timing can be regulated by rotating machinery timer shell, when timer moves to the scheduled time, make tripping mechanism break away from back the power dial, return the power dial and turned round by return spring elastic force, thereby drive knob off switch body, cut off source of the gas.
After the utility model adopts said structure, mechanical timer, tripping mechanism are reached back the power dial and burnt gas switch is well combined, reach the purpose that timing automatic is closed source of the gas, prevent unnecessary loss, can prevent the generation of fire accident effectively, ensure people's the security of the lives and property.
Description of drawings:
Fig. 1 is the sectional view 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 axle 6 and Switch main body 8, and knob 1 is by projection and switch axle 6 upper groove clampings on it, the join opening and closing of control switch body 8 of switch axle 6 and Switch main body 8.
For realizing the timing automatic off switch, cross-under has mechanical timer 3 on switch axle 6, and mechanical timer 3 has a hollow shaft 30 and shell 31, and reduction gear 7 and energy storage wind spring 9 are installed in the space between shell 31 and hollow shaft 30.Tripping mechanism 5 is installed successively on mechanical timer 3 tops, returns power dial 2, return power dial 2 and go here and there in mechanical timer 3 hollow shafts 30 peripheries, its underpart is provided with groove, in be provided with return spring 4; Tripping mechanism 5 be positioned at back power dial 2 belows and with return power dial 2 buckle mutually.
Return power dial 2 and be provided with a latch 20, peg graft, move together thereby drive the two with knob 1 bottom.
During the utility model work, rotary knob 1 drives switch axle 6 and opens Switch main body 8, open source of the gas, and drives back power dial 2 by latch 20 and rotate, return spring 4 produces elastic force at this moment, but because of tripping mechanism 5 with return power dial 2 mutually buckle block back power dial 2, so returning power dial 2 does not temporarily turn round, mechanical timer 3 picks up counting simultaneously, and the length of timing can be regulated by rotating machinery timer 3 shells 30, when timer moves to the scheduled time, make tripping mechanism 5 break away from back power dial 2, return power dial 2 and turned round by return spring 4 elastic force, thereby drive knob 1 off switch body 8, cut off source of the gas.
In sum, the utility model is simple in structure, and it is convenient to use, and mechanical 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.
