Abstract
A kind of safe preventing gas leaks gas-cooker, it comprises the first air valve, first air valve is connected with one end of ratchet, the top of the ratchet other end is provided with tooth bar, tooth bar upper surface is provided with metal derby, the connecting portion of tooth bar is connected with the second air valve, and the top of metal derby is provided with electromagnet, and electromagnet becomes closed-loop path with infrared sensing switch, power sources in series; Block is provided with above ratchet.The utility model can solve existing gas-cooker when flame-out but air valve does not close combustion gas can be caused to leak bring the problem of threat to resident's life.
Description
Technical field
The utility model relates to a kind of gas-cooker, is specifically related to the gas-cooker that a kind of preventing gas leaks.
Background technology
Gas-cooker is firing equipment common in Modern Family, if but improper use, be also easy to the danger such as gas leakage, blast occurs.The main cause of gas leakage has: 1. gas-cooker is aging; 2., in unattended situation, heat food causes soup to drench flame-out flame; 3. pipeline pressure reduces suddenly and occurs that cutoff causes natural gas to be revealed; 4. switch is not closed tight.If the non-Timeliness coverage of these gas leakage situations, once run into spark or flare, then very likely blast, life property safety in serious threat.
There are three kinds of safety protection device for gas cookers in the market:
The first generation is the memory metal protection system appeared on the market for about 1994, and this protection system carries out auto extinguishing protection by the characteristic of memory metal.Its shortcoming is that memory metal can damage gradually by flame high temperature action for a long time; Its thermal inertia is large, and easily generation action is delayed, can only extinguish rear clock more than 2 points and just play a role, have a lot of gas leakage in this time at fire, dangerous relatively large.
The second generation is exactly thermojunction type blowout protection system common in the market.This system be have thermocouple and magnetic valve dimerous.Produce heat difference electromotive force when thermocouple is heated, its coil entering magnetic valve produces magnetic field makes magnetic valve action.About wanting preheating 10 second when this system starts, some client thinks that inconvenience is also uncomfortable.Its burnout time controls, at about 40 seconds, still to there is gas leakage hidden danger.
The third generation is exactly current state-of-the-art ion induction technology.Whether ion safety shutdown protection type gas-cooker have employed advanced ion flame-out protection device, utilize the electric conductivity of flare, can be extinguished by ion probe perception flame.If extinguished, immediately by cutting off fuel gas path to the control of magnetic valve.Its reaction speed can reach 0.1 second, so would not occur dangerous.These type of kitchen range are generally lighted a fire also very rapid.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and the safe preventing gas of the one provided leaks gas-cooker, it can solve existing gas-cooker when flame-out but air valve does not close combustion gas can be caused to leak bring the problem of threat to resident's life.
The object of utility model is achieved in that
A kind of safe preventing gas leaks gas-cooker, it comprises the first air valve, first air valve is connected with one end of ratchet, the top of the ratchet other end is provided with tooth bar, tooth bar upper surface is provided with metal derby, the connecting portion of tooth bar is connected with the second air valve, and the top of metal derby is provided with electromagnet, and electromagnet becomes closed-loop path with infrared sensing switch, power sources in series; Block is provided with above ratchet.
Optionally, regular tap is in series with in the closed-loop path of electromagnetic block and infrared sensing switch, electric power generating composition.
Optionally, metal derby is iron block or nickel block or cobalt block.
Concrete, metal derby is the projection of surface for arc shape, and electromagnet is located at metal derby oblique upper.
The utility model achieves following technique effect:
Adopt said structure, during use, pressing, rotate to open the first air valve and upwards stirred one end of tooth bar by the ratchet be connected with the first air valve, one end of such ratchet and tooth bar pushes against fixing second air valve that simultaneously makes in the state of opening, 2 air valves are opened rear gas-cooker simultaneously and are released spark ignition combustion gas, like this while gas-cooker normally works, infra-red sensor switch can connect whole loop after the infrared ray that flame is released being detected, electromagnet can make metal derby move upward using of magnetic force after powered up simultaneously, tooth bar move upward to a certain extent after separate with ratchet, by driving reinstatement state under the effect of other end wind spring in the first air valve of such ratchet, when gas-cooker is at accident extinguishing, infra-red sensor switch is closed, and metal derby loses the attraction of electromagnet and resets under the built-in wind spring effect of the second air valve, the second air valve can be closed like this, effectively prevent combustion gas and leak.
Adopt the structure being in series with regular tap in the closed-loop path of electromagnetic block and infrared sensing switch, electric power generating composition, such user can control the opening and closing situation of whole circuit according to actual conditions.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2-Fig. 4 is the working state figure of the utility model valve part.
Detailed description of the invention
A kind of safe preventing gas leaks gas-cooker as shown in Figure 1, it comprises the first air valve 1, first air valve 1 is connected with one end of ratchet 2, the top of ratchet 2 other end is provided with tooth bar 3, tooth bar 3 upper surface is provided with metal derby 4, the connecting portion of tooth bar 3 is connected with the second air valve 5, and the top of metal derby 4 is provided with electromagnet 6, and electromagnet 6 and infrared sensing switch 7, power supply 8 are connected into closed-loop path; Block 10 is provided with above ratchet 2.
Regular tap 9 is in series with in the closed-loop path that described electromagnetic block 6 and infrared sensing switch 7, power supply 8 are formed.
Described metal derby 4 is iron block or nickel block or cobalt block.
Described metal derby 4 is the projection of surface for arc shape, and electromagnet 6 is located at metal derby 4 oblique upper.
One end and the support of described block 10 are fixed, and after the end of ratchet 2 and the end of tooth bar 3 push against, the continuation that block 10 and detent contact can limit ratchet move.
As shown in figs 2-4, adopt said structure, during use, pressing, rotate to open the first air valve and upwards stirred one end of tooth bar by the ratchet be connected with the first air valve, one end of such ratchet and tooth bar pushes against fixing second air valve that simultaneously makes in the state of opening, 2 air valves are opened rear gas-cooker simultaneously and are released spark ignition combustion gas, like this while gas-cooker normally works, infra-red sensor switch can connect whole loop after the infrared ray that flame is released being detected, electromagnet can make metal derby move upward using of magnetic force after powered up simultaneously, tooth bar move upward to a certain extent after separate with ratchet, by driving reinstatement state under the effect of the other end first wind spring 11 in the first air valve of such ratchet, when gas-cooker is at accident extinguishing, infra-red sensor switch is closed, and metal derby loses the attraction of electromagnet and resets under built-in second wind spring 12 of the second air valve acts on, and the second air valve can be closed like this, effectively prevent combustion gas and leak,
Be in series with the structure of regular tap in closed-loop path by electromagnetic block and infrared sensing switch, electric power generating composition, such user can control the opening and closing situation of whole circuit according to actual conditions.
