[0023] The present utility model will be further described below with reference to the accompanying drawings:

[0024] Embodiment 1:

[0025] As shown in Figure 1 , 2 , 6 and 7, a planetary gear motor for controlling a gas valve of a gas stove includes a motor body 01, a gearbox 02, a paddle 03, a circuit board 04, a magnetic code disk 05, a Hall sensor 06 and a connection cable 07. A rotating shaft 011 is provided in the middle of the motor body 01. The rotating shaft 011 penetrates the motor body 01 and protrudes from both ends of the motor body 01. A positive and negative electrode 012 is provided at one end of the motor body 01. The gearbox 02 is fixed to the other end of the motor body 01 and is in transmission connection with the rotating shaft 011 of the motor body 01. The paddle 03 is fixed to the power output end of the gearbox 02. The circuit board 04 is fixed to the end of the motor body 01. The positive and negative electrode 012 is electrically connected to the circuit board 04. The end of the rotating shaft 011 passes through the circuit board 04 and is fixedly connected to the middle of the magnetic code disk 05. The Hall sensor 06 is fixed on the circuit board 04 and corresponds to one side of the magnetic code disk 05. Both the Hall sensor 06 and the connection cable 07 are electrically connected to the circuit board 04.

[0026] The circuit board 04 is connected to the control system through the connection cable 07. When it is necessary to open the gas valve, the control system gives a signal to the circuit board 04. The circuit board 04 is connected to the positive and negative electrode 012 to control the rotation of the rotating shaft 011 on the motor body 01. Then, after speed change through the gearbox 02, the paddle 03 is driven to rotate, so as to open the gas valve through the paddle 03. The rotation of the rotating shaft 011 simultaneously drives the magnetic code disk 05 to rotate. The Hall sensor 06 is used in cooperation with the magnetic code disk 05 to detect and control the rotation angle of the rotating shaft 011, and then control the rotation angle of the paddle 03, so as to control the opening amplitude of the gas valve. When it is necessary to close the gas valve, the same principle is adopted. The advantage of this design is that it can intelligently control the opening and closing of the gas valve and adjust the ventilation amount through the circuit board 04, so as to realize the remote operation of the gas valve, bringing convenience and safety to cooking. Through the magnetic code disk 05 and the Hall sensor 06, the opening amplitude of the gas valve can be accurately controlled, making the control more accurate and stable.

[0027] In this design, it further includes a connecting bracket 08. The connecting bracket 08 is fixed on the outer periphery of the gearbox 02 and close to the side of the paddle 03. The connecting bracket 08 is used to connect with the housing of the gas stove, so as to fix the motor body 01 and the gearbox 02.

[0028] The connecting bracket 08 and the gearbox 02 are integrally arranged, which can make the connection between the connecting bracket 08 and the gearbox 02 more firm.

[0029] The magnetic code disk 05 is provided with an annular groove 051 on one side corresponding to the circuit board 04, which can reduce the weight of the magnetic code disk 05, so that the rotating shaft 011 is not easily bent and deformed during use, and the service life is improved.

[0030] In this design, it further includes a flexible cable connecting block 09. The flexible cable connecting block 09 is fixed on the circuit board 04. The end of the connecting flexible cable 07 passes through the flexible cable connecting block 09 and is electrically connected to the circuit board 04. The flexible cable connecting block 09 can protect the connection position between the connecting flexible cable and the circuit board 04, preventing external moisture from entering and causing short circuit or rust at the connection.

[0031] The flexible cable connecting block 09 corresponds to one side of the Hall sensor 06. An opening is provided on the outer side of the flexible cable connecting block 09 along the radial direction of the motor body 01. The end of the connecting flexible cable 07 passes through the opening of the flexible cable connecting block 09 and is electrically connected to the circuit board 04. The connecting flexible cable 07 extends towards the radial outer side of the magnetic code disk 05 and is connected to the control system.

[0032] Embodiment 2:

[0033] As Figures 3 to 5 shown, this embodiment is basically the same as Embodiment 1, and the difference is that the flexible cable connecting block 09 corresponds to one side of the motor body 01. An opening is provided on the flexible cable connecting block 09 along the axial direction of the motor body 01. The end of the connecting flexible cable 07 passes through the opening of the flexible cable connecting block 09 and is electrically connected to the circuit board 04.

[0034] The flexible cable connecting block 09 and the magnetic code disk 05 are on both sides of the circuit board 04 respectively. The connecting flexible cable 07 extends along the axial direction and is connected to the control system, which can avoid the magnetic code disk 05 contacting the connecting flexible cable 07 during rotation, reduce the wear of the connecting flexible cable 07, improve the service life, and also make the angle detection and control of the paddle 03 more accurate.

[0035] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
