[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, a knob 100 with digital display and timing control includes: a shading cover 101, a display panel 102, a connector 103, a knob body 104, a timing adjustment ring 105, a timing positioner 106, a gear positioner 108, and a multi-gear valve body 109, wherein the gear positioner 108, the timing positioner 106, and the display panel 102 are all externally connected to a controller.

[0020] The valve stem of the multi-position valve body 109 is sequentially equipped with a position shifter 108, a timing position shifter 106, and a knob body 104. The position shifter 108 is inserted into the valve stem of the multi-position valve body 109, and its base is fixed to the valve body bracket at the upper end of the multi-position valve body 109 by screws; the knob body 104 is installed above the multi-position valve body 109 by tightly fitting with the valve stem, and the inner ring of the position shifter 108 rotates with the knob body 104 and the valve stem and senses the fire power position.

[0021] The timing adjustment ring 105 is fixed to the upper outer ring of the timing positioner 106 by a buckle structure. The timing adjustment ring 105 drives the timing positioner 106 to rotate and adjust the timing time. The timing adjustment ring 105 can rotate 360 ​​degrees to adjust the timing time, and cyclically adjust within a preset time range such as 0-180 minutes. The connecting piece 103 passes through the knob body 104, and the lower end of the connecting piece 103 is fixed to the side of the valve body bracket at the upper end of the multi-speed valve body 109 by a screw, and its upper end is located on the knob body 104. The upper inner cavity of the knob body 104 has an avoidance groove in the structure to prevent interference with the connecting piece 103 during rotation; the display panel 102 that can display the firepower gear or the timing time is fixed on the top of the connecting piece 103, and the display panel 102 is separated from the connecting piece 103 by an insulating piece; the shading cover 101 is fixed to the top of the knob body 104 by a snap-fit ​​structure, and the shading plate 101 and the knob body 104 are bonded with waterproof glue, and the connecting piece 103 and the display panel 102 are a permanent fixed structure and are not affected by the rotation of any part.

[0022] The knob 100 with digital display and timing control drives the multi-position valve body 109 valve stem to rotate and adjust the gear firepower through the knob body 104, and the gear position changer 108 rotates with the valve stem, and the display board 102 displays the corresponding firepower gear on the top of the knob; the timing position changer 106 is driven to rotate and adjust the timing time through the timing adjustment ring 105, and the display board 102 displays the corresponding timing time on the top of the knob. The above two adjustment actions are performed independently and do not interfere with each other. When the above two adjustment actions occur at the same time, the display board 102 switches to display the firepower gear and the timing time.

[0023] The knob 100 with digital display and timing control can realize the functions of timing adjustment, timing display, gear adjustment, and gear display at the same time. The timing adjustment operation is more convenient, and the time display and gear display are more intuitive. When the knob body 104 of the knob 100 with digital display and timing control is rotated alone, the gear changes, and the timing adjustment ring 105 does not rotate accordingly; on the contrary, when the timing adjustment ring 105 is rotated alone, the timing time changes, and the knob body 104 does not rotate accordingly.

[0024] like Figure 3As shown, a double-burner gas stove has two burners, left and right, including two knobs 100 with digital display and timing control for respectively controlling the left and right burners, and also includes a controller 200. The controller 200 is electrically connected to a gear position changer 108, a timing position changer 106, and a display panel 102, and the display panel 102 displays the fire position or timing time of the gas stove. The signal generated by rotating the gear position changer 108 and the timing position changer 106 is sent to the controller 200, and the controller feeds back the signal to the display panel 102, and the corresponding information is displayed immediately.

[0025] Furthermore, it also includes a waterproof ring 107, which is installed below the timing positioner 106. The base of the timing positioner 106 is fixedly connected to the waterproof ring 107, and the waterproof ring 107 is also glued above the stove glass panel by waterproof glue.

[0026] When the knob body 104 is rotated, the digital display tube in the middle of the display board will display the corresponding gear position; when the timing adjustment circle 105 drives the timing positioner 106 to rotate, the digital display tube in the middle of the display board will display the remaining timing time of the stove. When the timing time is "0", the controller sends a command to the corresponding burner to stop working after receiving the signal.

[0027] The shading plate 101 and the knob body 104 are bonded by waterproof adhesive, and the waterproof ring 107 and the glass panel of the stove are bonded by waterproof adhesive, so as to effectively protect the knob and the electronic components in the valve body.

[0028] When operating the knob 100 with digital display and timing control in this example, the gas stove can be turned on for cooking by turning the knob body 104, and the required firepower gear can be selected by turning the knob body 104, and the display panel 102 will then display the gear number. When the gas stove needs to be turned off at a certain time, the required timing time can be selected by turning the timing adjustment circle 105 to a specific position, and the display panel will then display the remaining timing time, and the stove will start to count down. At this time, the timing time and the gear switch display. After the timing ends, the controller 200 can provide a reverse pulse current to act on the excitation coil of the solenoid valve to generate a magnetic field opposite to the solenoid valve studio, thereby turning off the solenoid valve, turning off the gas, and ending the operation of the stove burner. The user can select the timing time by rotating the timing adjustment circle 105 360°. If the timing time needs to be changed during operation, the timing adjustment circle 105 can also be directly rotated, which is very convenient to operate.
