[0035] Referring to Figure 1 The present application provides a kind of to pour protection device, which includes gas pipeline 1, ignition device 4, thermoelectric conversion component 3, electromagnetic valve 2 and inclination detection module 5;Wherein:

[0036] Gas pipeline 1, one end of gas pipeline 1 is used to supply gas;

[0037] Electromagnetic valve 2, electromagnetic valve 2 is arranged in gas pipeline 1;

[0038] Thermoelectric conversion component 3, thermoelectric conversion component 3 is electrically connected with electromagnetic valve 2;

[0039] Inclination detection module 5, inclination detection module 5 is electrically connected with electromagnetic valve 2;

[0040] When electromagnetic valve 2 opens to gas pipeline 1 conduction, thermoelectric conversion component 3 outputs keep signal to electromagnetic valve 2 when receiving the heat generated by gas pipeline 1 exhaust gas is ignited, to make electromagnetic valve 2 keep open state;

[0041] When the tilt detection module 5 detects a tilting action, it outputs a shut-off signal to the solenoid valve 2 to close the solenoid valve 2 until the gas pipeline 1 is cut off.

[0042] In this embodiment, the gas pipeline 1 can be as follows: Figure 1 The passageway shown can be an internal component of a gas pipeline, or a pipe assembly; no limitation is made here. Preferably, the end of the gas pipeline 1 that supplies gas is the lower end, and the end that discharges gas is the upper end. The gas discharged upwards from the gas pipeline 1 can be ignited by the ignition device 4 to produce a flame that can be used for heating or other functions. This arrangement adapts to the combustion direction of the flame and avoids direct contact between the flame and the gas in the gas pipeline 1, thus preventing safety hazards. The ignition device 4 can be an ignition needle electrically connected to a high-pressure generator. When an ignition signal is input to the high-pressure generator, the high-pressure generator outputs a 12-18KV pulse voltage to the ignition needle, causing the ignition needle to perform the ignition operation and ignite the gas discharged from the gas pipeline 1. The solenoid valve 2 can convert electrical energy into magnetic force, which drives the valve body to move, thereby regulating the gas flow rate in the gas pipeline 1. The thermoelectric conversion assembly 3 may include a thermocouple 31 or other devices that can convert heat energy into electrical energy.

[0043] It should be noted that, in addition to being driven by magnetic force, the solenoid valve 2 can also be moved by directly applying external force. Specifically, in this embodiment, the solenoid valve 2 initially blocks the gas pipeline 1. When gas equipment needs to be used, external force can be applied directly or through other actuators to the valve body of the solenoid valve 2, causing it to open to a fully open state for gas pipeline 1, and then igniting via the ignition device 4. When the thermoelectric conversion device receives the heat from the flame generated by the ignition operation, it outputs a holding signal to the solenoid valve 2. Specifically, the thermoelectric conversion component 3 outputs electrical energy converted from thermal energy to the solenoid valve 2, energizing it and generating magnetic force to attract the valve body to its current position (i.e., the position where gas pipeline 1 is open after being driven by external force). This prevents the valve body from returning to its original position and causing gas pipeline 1 to close again, thus ensuring normal gas supply and normal combustion operation of the gas equipment.

[0044] The signal processing unit (including but not limited to a microcontroller, a single-chip microcomputer, etc.) can be arranged in the inclination detection module 5 to coordinate the processing of various signals. The inclination detection module 5 can be simultaneously provided with a sensing device (such as an angle sensor, a displacement sensor, a position sensor, etc.) for sensing the change in spatial position and be preset with a threshold value for defining whether the tipping occurs. For example, when the angle sensor detects that the inclination angle of the gas equipment is greater than the preset angle threshold value, it is judged that the gas equipment is tipping at this time, and then the inclination detection module 5 can send a closing signal to the electromagnetic valve 2 through the above-mentioned signal processing unit, so that the electromagnetic valve 2 is closed to the state of cutting off the gas pipeline 1. Since the gas cannot be supplied to the ignition device 4 through the gas pipeline 1 at this time, the flame cannot continue to be generated, thereby effectively resolving the fire hazard existing after the gas equipment is tipped. The closing signal sent by the inclination detection module 5 to the electromagnetic valve 2 can be a signal for preventing the electromagnetic valve 2 from being continuously powered, for example, a counter electromotive force corresponding to the electromotive force loaded on the electromagnetic valve 2 by the thermoelectric conversion device. In this way, the magnetic force of the electromagnetic valve 2 disappears, and no attracting force is generated on the valve body part, so that the valve body part returns to the initial state before the external force is applied. At this time, the gas pipeline 1 is blocked and cut off by the valve body part.

[0045] As can be seen, the tipping protection device provided in the embodiment can perform the ignition operation on the gas discharged from the gas pipeline 1 when the electromagnetic valve 2 is opened to the on state of the gas pipeline 1. When the thermoelectric conversion assembly 3 receives the heat of the flame generated by the ignition operation, a holding signal is output to the electromagnetic valve 2. The holding signal makes the electromagnetic valve 2 enter the state of being powered to generate a magnetic force, so that the electromagnetic valve 2 is maintained in the current open state by the magnetic attraction, the gas pipeline 1 is maintained in the on state, the gas can be normally supplied, and the gas equipment can normally burn and operate. When the inclination detection module 5 detects the tipping action, a closing signal is output to the electromagnetic valve 2, so that the electromagnetic valve 2 loses the magnetic force and returns to the state of blocking the gas pipeline 1. The gas pipeline 1 is cut off, and the gas cannot continue to be supplied, thereby effectively resolving the fire hazard existing after the gas equipment is tipped, and improving the safety performance of the gas equipment.

[0046] Further, with reference to Figure 1 In an exemplary embodiment, the tipping protection device further comprises an actuating assembly 6, the gas pipeline 1 comprises a first channel 11 and a second channel 12, and the electromagnetic valve 2 comprises a valve body 21. Wherein:

[0047] The first channel 11 and the second channel 12 are in communication, and one end of the first channel 11 is used for supplying the gas.

[0048] The actuating assembly 6 is slidably connected to one end of the second channel 12, and the valve body 21 is slidably connected to the other end of the second channel 12. The actuating assembly 6 is used to bear a pressing force and move towards the other end of the second channel 12 to push the valve body 21 to move in a direction away from the first channel 11 until the first channel 11 is open.

[0049] In this embodiment, the first channel 11 is vertically arranged, and the second channel 12 is horizontally arranged. The middle part of the second channel 12 is communicated with the first channel 11. The actuating assembly 6 can include a manual valve having a holding portion 62 and a valve body portion connected thereto. For example, the valve body portion of the manual valve is slidably connected to the left end of the second channel 12, and the valve body 21 (which can include a valve rod) of the electromagnetic valve 2 is slidably connected to the right end of the second channel 12 (see the description of the electromagnetic valve 2 in the previous embodiment). The user can press the holding portion 62 to move the valve body portion of the manual valve to the right to push the valve body 21 of the electromagnetic valve 2 to the right of the first channel 11 by the valve body portion of the manual valve. At this time, the valve body 21 of the electromagnetic valve 2 no longer blocks the first channel 11, and the gas can be discharged upward to the ignition device 4 through the first channel 11 to perform subsequent operations. The specific process can be seen in the previous embodiment, which will not be described here. After the actuating assembly 6 completes the above operation, the user can pull the actuating assembly 6 back to the initial position (the leftmost end of the second channel 12) to avoid hindering the subsequent gas supply process. Of course, a reset assembly can also be provided on the actuating assembly 6 to automatically reset it.

[0050] Specifically, referring to Figure 1 , the actuating assembly 6 includes a push rod 61 and a first elastic member 63. The push rod 61 is slidably connected to one end of the second channel 12. One end of the first elastic member 63 is connected to the push rod 61, and the other end of the first elastic member 63 is connected to one end of the second channel 12. The first elastic member 63 is used to apply an elastic force to the push rod 61 to move the push rod 61 in a direction away from the electromagnetic valve 2.

[0051] Here, the push rod 61 corresponds to the valve body portion of the actuating assembly 6, and the first elastic member 63 corresponds to the reset assembly. The first elastic member 63 can be a spring, a plastic member with elastic force, a hydraulic or pneumatic element, or any device that can generate elastic potential energy. The first elastic member 63 should be in a compressed state, which can provide a buffering effect when the user applies a pressing force to the push rod 61, and automatically drive the push rod 61 to reset when the user stops applying the pressing force to the push rod 61, thereby improving the convenience of use.

[0052] Further, referring to Figure 1In an exemplary embodiment, the electromagnetic valve 2 further comprises an electromagnetic coil 22, which is arranged at the other end of the second channel 12 and is electrically connected with the thermoelectric conversion assembly 3 and the inclination detection module 5.

[0053] The electromagnetic coil 22 generates a magnetic force when receiving the holding signal and attracts the valve body 21, so that the valve body 21 is fixed at the current position; the electromagnetic coil 22 disappears the magnetic force when receiving the closing signal and stops attracting the valve body 21.

[0054] In the embodiment, the electromagnetic coil 22 can convert the electric energy into the magnetic force, and correspondingly, the holding signal can be the electromotive force provided by the thermoelectric conversion assembly 3 to the electromagnetic coil 22 after converting the flame heat energy. The electromagnetic coil 22 generates the magnetic force after receiving the electric energy, and attracts the valve body 21 to the current position (i.e. drives the valve body 21 to move to the position which does not block the first channel 11 by the external force), so as to avoid the valve body 21 returning to the position and blocking the first channel 11 again, thereby ensuring the smooth supply of the gas in the normal use state of the gas equipment; when the electromagnetic coil 22 loses the electric energy, the magnetic force disappears and no longer attracts the valve body 21, at this time, the valve body 21 can return to the initial position.

[0055] For the complete working process of the electromagnetic coil 22 cooperating with other devices, reference can be made to the description of the above-mentioned embodiment, which will not be described here again.

[0056] Specifically, referring to Figure 1 , the electromagnetic valve 2 further comprises a second elastic member 23, one end of the second elastic member 23 is connected with the valve body 21, and the other end of the second elastic member 23 is connected with the other end of the second channel 12; the second elastic member 23 is used to apply an elastic force to the valve body 21, which can move the valve body 21 in the direction close to the actuating assembly 6.

[0057] The second elastic member 23 can be a spring, a plastic member with elastic force, a hydraulic or pneumatic element, or other devices that can generate elastic potential energy. The second elastic member 23 should be arranged in a compressed state, so as to form a buffering effect when the user applies an external force to the valve body 21, and at the same time, drive the valve body 21 to automatically reset when the electromagnetic coil 22 loses the electric energy and the magnetic force disappears and no longer attracts the valve body 21, thereby improving the use convenience.

[0058] Further, referring to Figure 1 In an exemplary embodiment, the thermoelectric conversion assembly 3 comprises a thermocouple 31, which is electrically connected with the electromagnetic coil 22 through the first loop 7.

[0059] The thermocouple 31 generates an electromotive force signal when receiving the heat generated after the gas discharged by the gas pipeline 1 is ignited, and outputs the electromotive force signal to the electromagnetic coil 22 through the first loop 7, so that the electromagnetic coil 22 generates a magnetic force and attracts the valve body 21.

[0060] In particular, with reference to Figure 1 , the tilt detection module 5 is electrically connected to the electromagnetic coil 22 through the second circuit 8, and the reverse electromotive force signal output by the tilt detection module 5 to the electromagnetic coil 22 through the second circuit 8 is a closing signal.

[0061] The thermocouple 31 adopts the thermoelectric effect, and its working principle is to weld two conductors or semiconductors of different materials to form a closed circuit. When there is a temperature difference between the two conductors or semiconductors, an electromotive force will be generated between them, and in turn an electric current will be formed in the closed circuit. In this embodiment, the closed circuit is the first circuit 7. The reverse electromotive force output by the tilt detection module 5 to the electromagnetic coil 22 through the second circuit 8 can offset the electromotive force generated by the thermocouple 31 on the first circuit 7, so as to make the electromagnetic coil 22 lose power and the magnetic force disappear, and no longer have the suction effect.

[0062] In this embodiment, the tilt detection module 5 is connected in parallel to the flameout protection circuit (i.e. the first circuit 7 formed by the thermocouple 31 and the electromagnetic coil 22 in series), and when the gas appliance is tilted, the tilt detection module 5 outputs a reverse electromotive force to the electromagnetic coil 22, which controls the electromagnetic valve 2 to close in time, thereby cutting off the first channel 11 and stopping the supply of gas.

[0063] In actual application, if the thermocouple 31, the electromagnetic coil 22 and the tilt detection module 5 are connected in series, or a mechanical tilt switch is connected in series between the thermocouple 31 and the electromagnetic coil 22, the internal resistance of the thermocouple 31 will gradually increase with the increase of the use time of the gas appliance, or the contact points of the mechanical tilt switch will gradually oxidize and the internal resistance of the contact points will gradually increase, which will cause the internal resistance of the flameout protection circuit to gradually increase, and eventually cause the electromagnetic valve 2 (specifically the electromagnetic coil 22) to fail to work normally, and the gas appliance cannot be used normally.

[0064] In this embodiment, since the tilt detection module 5 is connected in parallel to the flameout protection circuit, the internal resistance of the flameout protection circuit will not be affected when the gas appliance is working normally, so as to further improve the stability of the gas appliance.

[0065] Further, with reference to Figure 1 , in an exemplary embodiment, the tilt detection module 5 includes any one or more of an angle sensor, a displacement sensor, and a position sensor.

[0066] In the embodiment, a threshold value for defining whether the tipping occurs can be preset for the tilt detection module 5. For example, when the angle sensor detects that the tilt angle of the gas equipment is greater than the preset angle threshold value, it is determined that the gas equipment tips over at this time, and the tipping protection operation is started (for details, refer to the above embodiment). The displacement sensor and the position sensor are the same, and are not described here.

[0067] Correspondingly, the embodiment of the present application also provides a gas equipment, which comprises the tipping protection device in any of the above embodiments.

[0068] In the embodiment, the gas equipment can include any equipment using gas as energy, and using the heat generated by burning gas for heating, cooking, heating, atomization and other functions, such as a gas heater, a gas stove and the like. For the specific structure of the tipping protection device, refer to the above embodiments. Since the gas equipment adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which are not described here.

[0069] It should be noted that other contents of the tipping protection device and the gas equipment disclosed in the present application can refer to the prior art, which are not described here.

[0070] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields within the concept of the present application, and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
