Abstract
An electric gas shutoff valve is disclosed. The electric gas shutoff valve includes a breaker body with an inlet channel and an exhaust channel. A gas breaker panel is pivotally connected to a chamber in the breaker body. One end of the gas breaker panel is a channel block while a connection portion on the other end thereof is hooked with a vertical hook mounted in the breaker body. A gas detection unit is arranged outside the breaker body and coupled to a control unit. The control unit is coupled to a drive unit. Once the gas detection unit detects abnormal gas flow during leak caused by pipeline breakage or extinguished gas flame, the control unit activates the drive unit and the vertical hook is further driven to be released from the gas breaker panel. Thus the channel block blocks the exhaust channel and the gas supply is off.

When gas pipelines are broken or a gas flame on a gas appliance is out due to soup spilt while cooking food, a gas leak occurs. Refer to Fig. 6 and
10 Fig. 7, the data of the gas flow or concentration detected by the gas detection unit 6 is transmitted to the control unit 7 to be compared to the safety range set in the driver by the control unit 7. Once the data detected is over the safety range, the control unit 7 turns on the drive unit 8 to work.
At the moment, the drive unit 8 gives a magnetic force to attract the weights 34 on the bottom end of the vertical hook 3. Thus the weights 34 are moved toward the drive unit 8 on the side surface of the breaker body 1. At the same time, the vertical hook 3 is moved around the rotating shaft 17 and the hook portion 33 on top end of the vertical hook 3 is moved in the direction opposite to the weights 34 to be released from the projecting connection piece 271 of the connection portion 27 of the gas breaker panel 2. The channel block 23 on the other end of the gas breaker panel 2 is further released to obstruct the exhaust channel 14.

While the user has went out and found that the flame on the gas appliance at home was not off, he/she can send a drive signal to the communication unit 9 by using the application program already downloaded in the remote control device such as mobile phone, the PDA, the tablet computer, the notebook computer or the desktop computer. The drive single is transmitted to the communication unit 9 through internet or wireless (such as Wi-Fi). Then the communication unit 9 delivers the drive signal to the control unit 7 so that the control unit 7 drives to the drive unit 8 to act and attract the weights 34 on the bottom end of the vertical hook 3. Thus the hook portion 33 of the vertical hook 3 is moved and released from the projecting connection piece 271 of the connection portion 27 of the gas breaker panel 2. Therefore the channel block 23 on the gas breaker panel 2 is further moved to obstruct the exhaust channel 14 to stop the gas supply. The fire caused by the gas flame can be avoided.

12 breaker panel 2 is moved to obstruct the exhaust channel 14. Thus there is no risk of gas leak, gas explosion, or fire during the period.
Refer to Fig. 8, another embodiment is disclosed. In this embodiment, the drive unit 8 is arranged at the block button 5 and located outside the breaker body 1. The drive unit 8 can be an electromagnetic valve connected to the block button 5 and used for pushing the push rod 51 of the block button 5. When a gas leak occurs due to gas pipeline breakage or extinguished gas flame, and the gas flow or concentration detected by the gas detection unit 6 is over the safety range set in the control unit, the control unit 7 drives the drive unit 8 to act. At the moment, the drive unit 8 pushes the button portion 52 of the block button 5 so that the push rod 51 is also moved toward the chamber 15 of the breaker body 1 to lean against the weights 34 on the bottom end of the vertical hook 3. Thus the weights 34 are pushed to move. At the moment, the vertical hook 3 is moved around the rotating shaft 17 and the hook portion 33 on top end of the vertical hook 3 is also moved in the direction opposite to the pushed rod 51 to be released from the projecting connection piece 271 of the connection portion 27 of the gas breaker panel 2. Next the channel block 23 on the gas breaker panel 2 is fallen to obstruct the exhaust channel 14.
The gas supply is cut off and damages caused by the gas leak are avoided.
