[0025] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-5As shown, this utility model provides a smart shut-off device for a gas stove fire alarm, including a housing 1, a control circuit board 2 disposed within the housing 1, a turntable 3 rotatably disposed within the housing 1, and a switch reset assembly 4 disposed within the housing 1 for resetting the turntable 3. A limit switch 21 is electrically connected to the control circuit board 2. One side of the turntable 3 is operatively connected to the knob cover 6 of the gas stove switch, and the other side of the turntable 3 is operatively connected to the knob shaft 7 of the gas stove switch. The switch reset assembly 4 includes a stroke control component 41 rotatably disposed within the housing 1 and a rotation drive motor 42 disposed within the housing 1 for driving the stroke control component 41 to rotate. The power output end of the rotation drive motor 42 drives and connects to the stroke control component 41. The stroke control component 41 and the turntable 3 are operatively connected. A switch trigger protrusion 411 is provided on the stroke control component 41. The rotation drive motor 42 is electrically connected to the control circuit board 2. When the device is in the off state, the switch trigger protrusion... The switch trigger 411 abuts against the limit switch 21. When the device is in the open state, the switch trigger protrusion 411 moves away from the limit switch 21. The whole adopts an external structure. Users only need to connect the turntable 3 to the knob cover 6 and knob shaft 7 of the original gas stove switch. There is no need to modify the internal hardware of the gas stove. It can quickly replace the traditional button, has strong compatibility, reduces costs and meets the needs of large-scale popularization. The limit switch 21 and the turntable 3 are linked. Combined with the control circuit board 2, after the device is turned on, the user turns the knob cover 6 to drive the turntable 3 to rotate and trigger the limit switch 21. The control circuit board 2 starts timing. When the preset time is reached, it controls the rotation drive motor 42 to drive the limit control component 41 to drive the turntable 3 to reset, thereby forcibly closing the gas valve. It can effectively deal with scenarios where the user's attention is distracted, forgets, or suddenly leaves the place. It closes the valve switch from a physical level and effectively avoids fire or gas leakage accidents caused by human negligence, ensuring the safety of users.

[0026] In some embodiments of this utility model, the control circuit board 2 has a built-in functional module for a program that automatically shuts off the timer. The program is triggered by a limit switch. The functional module is a conventional technical means, which will not be described in detail in this utility model. Of course, other methods can also be used for automatic shut-off of the timer, and this utility model is not limited thereto.

[0027] The upper end face of the turntable 3 of this utility model is provided with a drive shaft 31, and the lower end face of the turntable 3 is provided with a knob shaft slot 32. The drive shaft 31 passes through the housing 1 and is connected to the knob cover 6. The end of the knob shaft 7 passes through the housing 1 and is inserted into the knob shaft slot 32. The user only needs to put the knob cover 6 of the original gas stove switch on the drive shaft 31 and insert the knob shaft 7 of the original gas stove switch into the knob shaft slot 32. The device can be easily and conveniently deployed on the traditional gas stove valve knob switch without changing the original structure of the gas stove. It is easy to deploy and highly practical.

[0028] The stroke control component 41 of this utility model is provided with a drive tooth 412 along the circumference. The power output end of the rotating drive motor 42 is connected to a bevel gear 421. The bevel gear 421 meshes with the drive tooth 412. The rotating drive motor 42 controls the stroke control component 41 to reset through the meshing of the bevel gear 421 and the drive tooth 412. The gear meshing connection can make the reset stroke more accurate, ensure the normal execution of the reset of the turntable 3, ensure that the gas stove valve closes accurately after the timer ends, and improve the safety of use.

[0029] In another embodiment of this utility model, such as Figure 6-8 As shown, the power output end of the rotary drive motor 42 is driven and connected to the bevel gear 421 through the telescopic transmission mechanism 9. The telescopic transmission mechanism 9 includes a spring fixing seat 91 mounted on the housing 1, a return torsion spring 92 mounted in the spring fixing seat 91, a bevel gear fixing seat 93 rotatably mounted in the spring fixing seat 91, and a transmission column 94 sleeved on the power output end of the rotary drive motor 42. One end of the return torsion spring 92 is engaged with the spring fixing seat 91, and the other end of the return torsion spring 92 is engaged with the bevel gear fixing seat 93. The fixed seat 93 is snapped into place, and the front end face of the bevel gear fixed seat 93 is fixedly connected to the bevel gear 421. A hollow transmission groove 931 is opened at the bottom of the bevel gear fixed seat 93. A transmission block 932 is provided on the side wall of the transmission groove 931. A spiral inclined surface 941 is opened on the side wall of the transmission column 94. The inclined surface 941 extends forward from the rear end in a clockwise direction. The transmission column 94 is inserted into the transmission groove 931. The transmission block 932 and the inclined surface 941 form an inclined surface pushing engagement. When the device is not turned on, the return torsion spring 9... 2. Push the bevel gear fixing seat 93 together with the bevel gear 421 away from the stroke control member 41. The transmission block 932 is located at the bottom of the inclined surface 941. At this time, the bevel gear 421 and the drive tooth 412 are disconnected. When the power output end of the rotating drive motor 42 rotates and drives the transmission column 94 to rotate, the inclined surface 941 pushes the transmission block 932, thereby pushing the bevel gear fixing seat 93 to rotate and move towards the stroke control member 41. This pushes the bevel gear 421 to mesh with the drive tooth 412, thus completing the rotation of the drive motor 42 to drive the stroke control member 41 to reset. When the rotating drive motor 42 stops rotating, the bevel gear fixing seat 93 is pushed open by the reset torsion spring 92. At this time, the transmission block 932 is located at the bottom of the inclined surface 941, so that the bevel gear 421 and the drive tooth 412 are disconnected. This process is repeated. The bevel gear 421 only meshes with the drive tooth 412 when the rotating drive motor 42 rotates. This can effectively prevent the user from jamming when rotating the knob cover 6, making it easy to use.

[0030] The stroke control component 41 of this utility model is provided with a first limiting component 414, and the turntable 3 is provided with a second limiting component 33 for driving the first limiting component 414 to rotate. The stroke control component 41 is connected to the turntable 3 through the first limiting component 414 and the second limiting component 33, so that the user can drive the stroke control component 41 to trigger the limit switch 21 when rotating the knob cover 6. After the timing ends, the stroke control component 41 drives the turntable 3 to reset, ensuring that the gas stove valve closes on time.

[0031] In this embodiment, the stroke control component 41 is a hollow annular structure. A limiting groove 413 is formed circumferentially on the inner sidewall of the stroke control component 41. A first limiting component 414 is formed at the end of the limiting groove 413. The turntable 3 is rotatably disposed within the stroke control component 41. A second limiting component 33 is formed radially protruding on the outer sidewall of the turntable 3, extending into the limiting groove 413. Figure 1 As shown, the second limiting member 33 abuts against the first limiting member 414 within the limiting groove 413. When the user rotates the knob cover 6 in the direction of the gas stove switch opening (counterclockwise), it drives the turntable 3 to rotate. The turntable 3, through the second limiting member 33, drives the first limiting member 414 to rotate counterclockwise as well. At this time, the switch trigger protrusion 411 on the travel control member 41 moves away from the travel switch 21, and the control circuit board 2 starts timing. If the user rotates the knob cover 6 before the timing ends, the turntable 3 rotates clockwise within the limiting groove 413. The second limiting member 33 does not need to drive the first limiting member 414, and the user can close the gas stove valve with less effort. After the timing ends, the drive motor 42 drives the stroke control component 41 to reset. If the user has not turned the knob cover 6 to close the gas stove switch valve before the timing ends, when the timing ends, the control circuit board 2 controls the drive motor 42 to drive the stroke control component 41 to rotate in the direction of closing the gas stove switch (clockwise). The first limit component 414 drives the second limit component 33, thereby driving the turntable 3 to rotate in the clockwise direction. The turntable 3 drives the knob shaft 7 to rotate, thereby completing the closing of the gas stove switch valve. Of course, other connection methods can also be used in this utility model to make the stroke control component 41 and the turntable 3 mutually connected and transmitted, all of which are within the protection scope of this utility model.

[0032] In another embodiment of this utility model, such as Figure 6-8As shown, the stroke control component 41 is a hollow ring structure. Several first driving teeth 415 are evenly arranged circumferentially on the inner sidewall of the stroke control component 41. The several first driving teeth 415 are formed into first limiting components 414. Several second transmission teeth 416 are arranged circumferentially on the outer sidewall of the turntable 3. The several second transmission teeth 416 are formed into second limiting components 33. The first driving teeth 415 and the second transmission teeth 416 are meshed and connected. Of course, other connection methods can also be used in this utility model to enable the stroke control component 41 and the turntable 3 to be mutually connected and transmitted, all of which are within the protection scope of this utility model.

[0033] The rotary drive motor 42 of this utility model can be set as a stepper motor, which can achieve precise angle control and accurately reset the turntable 3 to close the gas stove valve switch.

[0034] The bottom of the housing 1 of this utility model is provided with a battery compartment 8, and a battery assembly 81 is provided inside the battery compartment 8. The bottom of the battery compartment 8 is provided with a detachable battery cover 82. The battery assembly 81 is electrically connected to the control circuit board 2. The user can open the battery cover 82 to replace the battery 81. Compared with power supply, replacing the battery 81 is more convenient and easier for the user to use.

[0035] The housing 1 of this utility model is also equipped with an alarm 5, which is electrically connected to the control circuit board 2. In this embodiment, the alarm 5 is set as a buzzer, which can effectively remind the user to turn off the gas stove valve.

[0036] The housing 1 of this utility model is provided with a display screen 9, which is electrically connected to the control circuit board 2. The display screen 9 can display information such as preset time, which is convenient for users.

[0037] The housing 1 of this utility model is also provided with a function button 10, which is electrically connected to the control circuit board 2 to realize the function of adjusting the timing duration. Controlling the circuit board 2 through the button is a conventional technical means, which will not be described in detail here.

[0038] Working principle:

[0039] During operation, the user attaches the knob cover 6 of the original gas stove switch to the drive shaft 31 of the turntable 3. The knob shaft slot 32 of the turntable 3 is then attached to the switch valve knob shaft 7 of the gas stove. When the user rotates the knob cover 6, the turntable 3 rotates, thereby driving the travel control component 41 to move away and triggering the travel switch 21. At this time, the control circuit board 2 starts timing. The user can adjust the timing duration using the function button 10. When the timing on the control circuit board 2 ends, the control circuit board 2 controls the alarm 5 to sound an alarm and controls the rotation drive motor 42 to drive the turntable 3 to reset. The turntable 3 drives the switch valve knob shaft 7 to rotate to the closed position, thereby forcibly closing the gas valve. This effectively addresses scenarios where the user is distracted, forgetful, or suddenly leaves the area, physically closing the valve switch and effectively preventing fires or gas leaks caused by human negligence, thus ensuring the user's safety.

[0040] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
