[0029] The following specific embodiments will be further described in conjunction with the above-mentioned drawings.
[0030] In the following, various specific details are set forth in order to provide a thorough understanding of the concepts that form the basis of the described embodiments. However, it is obvious to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other cases, well-known processing steps are not specifically described.
[0031] Such as figure 1 As shown, a gas monitoring and alarm protection mechanism includes: a solenoid valve 1, a detection alarm 2 and a remote control 3. The remote controller 3 controls the opening and closing of the solenoid valve 1, and the detection alarm 2 detects whether the solenoid valve 3 leaks. Therefore, the gas monitoring and alarm protection mechanism can control the opening and closing of the solenoid valve 1 through the remote control 3, instead of the traditional manual closing valve, which brings convenience to the user, and when the gas leaks, the gas will diffuse to In the air, therefore, the detection alarm 2 can detect the gas, and an alarm is issued to remind the user to close the solenoid valve 1 to prevent the gas from continuing to leak, thereby playing a protective role.
[0032] Such as Figure 1-10 As shown, the solenoid valve 1 includes a control valve 100 and a controller 200. The controller 200 controls the opening and closing of the control valve 100; the control valve 100 includes a valve body 111, a sealing sleeve 112, a magnetic transmission sealing piston 113 and an electromagnet 114. The sealing sleeve 112 is arranged inside the valve body 111. The magnetic transmission sealing piston 113 is arranged inside the valve body 111. The electromagnet 114 is sleeved on the valve body 111. After the electromagnet 114 is energized, the magnetic transmission sealing piston 113 is pushed to reciprocate in the valve body 111 to realize the sealing and opening of the sealing sleeve 112. The controller 200 includes a first PCB board 210, a first circuit control module 211, a first communication module 212, a current conversion device 213 and a power supply device 214. The first circuit control module 211, the first communication module 212 and the current conversion device 213 are all arranged on the first PCB board 210. The first communication module 212 is wirelessly connected to the remote control 3 and the detection alarm 2. The current conversion device 213 is electrically connected to the electromagnet 114. The power supply device 214 is electrically connected to the first PCB board 210. Therefore, the remote control 2 generates a control signal, and the first communication module 212 receives the signal sent by the remote control 2. Therefore, the first circuit control module 211 can control the current switching device 213 to connect to the power supply device 214. When the control valve 100 When it needs to be closed, the current conversion device 213 controls the electromagnet 114 to be energized in the positive direction, so that the electromagnet 114 generates the same magnetism as the end of the magnetic transmission sealing piston 113, and therefore pushes the magnetic transmission sealing piston 113 to fit the sealing sleeve 112, When the solenoid valve 1 is closed, the electromagnet 114 is energized in the forward and reverse directions through the current conversion device 213, so that the electromagnet 114 generates magnetism that is different from the end of the magnetic transmission sealing piston 113, thus pushing the magnetic transmission sealing piston 113 and the sealing The sleeve 112 is separated and the solenoid valve 1 is ventilated, thus replacing the traditional need to manually open and close the valve. When the solenoid valve 1 forgets to close and causes gas leakage, the detection alarm 2 detects that the air is filled with gas, the detection alarm 2 sends an alarm prompt and sends a signal that the solenoid valve 1 is closed, so that the solenoid valve 1 is automatically closed.
[0033] Further, such as Figure 7-10 As shown, the detection alarm 2 includes an installation housing 201, a second PCB board 202, a second circuit control module 203, a combustible gas sensor 204, an alarm 205 and a power supply 206.

Therefore, the detection alarm 2 detects whether there is gas in the air through the combustible gas sensor 204, and when there is combustible gas, the synchronous alarm 205 sends out an alarm. The power supply 206 is connected to the home circuit to provide current to the detection alarm 2.
[0034] Further, a second communication module 207 and a third communication module 208 are also provided on the second PCB board 202, and the second communication module 207 is wirelessly connected to the first communication module 212 and the remote controller 3, so The third communication module 208 is connected to a smart phone. Therefore, when a signal is generated through the remote control 3, the first communication module 212 and the second communication module 207 simultaneously receive the signal from the remote control 3, so that the solenoid valve 1 can execute the signal sent by the remote control 3, and the detection alarm 2 can The state of the solenoid valve 1 is memorized to facilitate the detection of the alarm 2 to identify whether the solenoid valve 1 is on or off, and can be wirelessly connected to the remote control 3 through the second communication module 207, so when the remote control 3 is out of power, the alarm is detected The device 2 will also send out an alarm prompt to remind the battery to be used in the remote control 3. The third communication module 208 is connected to a smart phone. Therefore, the detection alarm 2 can transmit the detected information to the smart phone through the third communication module 208, and then the smart phone sends a signal to close the solenoid valve 1 and passes the The third communication module 208 receives the signal, and then the second communication module 207 transmits a signal to close the battery valve 1, so that the solenoid valve 1 is automatically closed to avoid gas leakage.
[0035] Further, the first communication module 212 and the second communication module 207 are both RF modules, and the third communication module 208 is a WiFi module.
[0036] Furthermore, a control box 121 is sleeved on the valve body 111, and the controller 200 is provided in the control box 121. Therefore, the controller 200 is installed and protected by the control box 121. The power supply device 214 is a lithium battery. Therefore, power is supplied to the controller 200 and the control valve 100 through the lithium battery, without the need for power supply, which makes the solenoid valve 1 easier to install and has a higher safety factor.
[0037] Furthermore, a distance sensor 220 is also provided on the first PCB board 210. Therefore, the position of the alarm 2 can be detected by the distance sensor 220.
[0038] Further, the first circuit control module 211 and the second circuit control module 203 are both single-chip microcomputers. Because the single-chip microcomputer has a programmable function, the first circuit control module 211 and the second circuit control module 203 can input programs to control the first communication module 212 and the current conversion device 213, as well as the combustible gas sensor 204 and alarm 205. The control and startup procedures of the second communication module 207 and the third communication module 208 can accurately control the opening and closing of the solenoid valve 1, and enable the detection alarm 2 to accurately detect the gas in the air and send an alarm signal.
[0039] Further, the current conversion device 213 is a MOS tube. Therefore, the current conversion is realized through the MOS tube.

Therefore, when the solenoid valve 1 is opened and the flame of the combustion furnace is extinguished, the gas flow rate in the valve body 111 will increase, so that the gas flow pushes the sealing plug 303 more than the tension spring 304, so that the sealing plug 303 is attached to the tapered sealing sleeve 301 to achieve a sealing effect on the first pipe joint 300, thereby preventing gas leakage.
[0042] Furthermore, the first pipe joint 300 is also provided with a magnetically permeable top rod 311, and a strong magnetic ring 312 is sleeved on the first pipe joint 300, and the strong magnetic ring 312 slides along the first pipe joint 300.
