A safety switch of a gas stove includes a main member including a cone valve chamber, a first chamber, a second chamber, an input tunnel, a first output tunnel and a second output tunnel connected to the second chamber and outside. A close member, an electromagnetic valve and a first temperature controller are mounted in the valve chamber, the first chamber and the second chamber respectively. A second temperature controller and a knob set are mounted on the main member. The knob set is connected to the close member, the first temperature controller and the electromagnetic valve to turn the close member and activate the first temperature controller and the electromagnetic valve for control of gas flowing into the input tunnel or flowing out of the first and second output tunnels. The present invention provides the functions of sequent ignition, shut the gas when flame is out, and temperature control.

What is claimed is: 1. A safety switch of a gas stove, comprising: a main member including a cone valve chamber, a first chamber, a second chamber, a first check port between the valve chamber and the first chamber, a second check port between the valve chamber and the second chamber, an input tunn
What is claimed is: 1. A safety switch of a gas stove, comprising: a main member including a cone valve chamber, a first chamber, a second chamber, a first check port between the valve chamber and the first chamber, a second check port between the valve chamber and the second chamber, an input tunnel connected to the first chamber, a first output tunnel and a second output tunnel connected to the second chamber and outside of the main member respectively; a close member, which includes at least a gas bore, received in the valve chamber and complementary to the valve chamber; an electromagnetic valve received in the first chamber to seal the first check port normally; a first temperature controller received in the second chamber and associated with the second check port to seal the second check port normally; a second temperature controller received in the second output tunnel with an end sensing a temperature of the gas stove to switch the second tunnel communicated with outside or not and change a gas flow rate; and a knob set mounted at the main member and connected to the close member, the first temperature controller and the electromagnetic valve to turn the close member and activate the first temperature controller and the electromagnetic valve. 2. The safety switch as defined in claim 1, wherein the main member further includes a gas tunnel communicated with the valve chamber and the first chamber, and the first check port is located between the gas tunnel and the first chamber. 3. The safety switch as defined in claim 2, wherein the gas tunnel is connected to a lateral side of the valve chamber and associated with the close member. 4. The safety switch as defined in claim 1, further comprising a control device movably mounted in the main member and associated with the first output tunnel to adjust a gas flow rate of the first output tunnel. 5. The safety switch as defined in claim 1, wherein the close member includes a close device with a center bore and the gas bore communicated with the center bore, a close shaft through the center bore of the close device, a rotary device connected to an end of the close shaft and a control valve. 6. The safety switch as defined in claim 5, wherein the close member further includes a fixed device mounted in the center bore of the close device to fix the close shaft in the center bore. 7. The safety switch as defined in claim 6, wherein the fixed device is a barrel. 8. The safety switch as defined in claim 6, wherein the close member further includes a leakage-proof device mounted on the fixed device and associated with the knob set. 9. The safety switch as defined in claim 8, wherein the leakage-proof device is an O-ring. 10. The safety switch as defined in claim 1, wherein the first temperature controller includes a sealing plate associated with the second check port and connected to the close member, a film cover and an elastic device between the sealing plate and the film cover. 11. The safety switch as defined in claim 10, wherein the first temperature controller further includes a thermal sensor, which is filled with a fluid with a high thermal expansion coefficient, mounted on the gas stove and connected to the film cover, which is a hollow member filled with a fluid with a high thermal expansion coefficient. 12. The safety switch as defined in claim 10, wherein the second temperature controller includes a housing, which has an outlet, connected to an output end of the second output tunnel, a valve mounted in the housing and associated with the outlet of the housing, and a thermal sensor mounted beside a burner of the gas stove and connected to the valve, wherein the thermal sensor and the valve are filled with a fluid with a high thermal expansion coefficient. 13. The safety switch as defined in claim 12, wherein the housing further includes a third check port associated with the outlet, and the valve switches the second output tunnel to be communicated with the outlet. 14. The safety switch as defined in claim 1, wherein the knob set includes a shaft connected to the close member, a pushing device through the main member and connected to the electromagnetic valve, and a driving device connected to the shaft and the pushing device to move the pushing device when the shaft is turned. 15. The safety switch as defined in claim 14, wherein the pushing device is connected to the electromagnetic valve through the first check port.
