[0018] The present invention will be further described in detail below with reference to the accompanying drawings.
[0019] As Figure 1 、 Figure 2 shown, a knob 100 with digital display and timing control includes: a light-shielding cover 101, a display board 102, a connecting member 103, a knob body 104, a timing adjustment ring 105, a timing shift changer 106, a gear shift changer 108, and a multi-gear valve body 109. The gear shift changer 108, the timing shift changer 106, and the display board 102 are all externally connected to a controller.
[0020] On the valve stem of the multi - gear valve body 109, a gear position changer 108, a timing changer 106, and a knob body 104 are successively installed. The gear position changer 108 is sleeved on the valve stem of the multi - gear valve body 109, and its base is fixed on the upper valve body bracket of the multi - gear valve body 109 by screws; the knob body 104 is installed above the multi - gear valve body 109 by being tightly fitted with the valve stem. The inner ring of the gear position changer 108 rotates with the knob body 104 and the valve stem and senses the fire power gear.
[0021] The timing adjustment ring 105 is fixed on the outer ring of the upper part of the timing changer 106 through a snap - fit structure. The timing changer 106 is driven to rotate by the timing adjustment ring 105 to adjust the timing time. The timing adjustment ring 105 can rotate 360° to adjust the timing time and cycle - adjust within a preset time range, such as within the range of 0 - 180 min; the connecting piece 103 passes through the knob body 104. The lower end of the connecting piece 103 is fixed to the side of the upper valve body bracket of the multi - gear valve body 109 by screws, and its upper end is located in the upper inner cavity of the knob body 104. An avoidance groove is provided in the structure of the knob body 104 to prevent interference with the connecting piece 103 during rotation; the display board 102 that can display the fire power gear or the timing time is fixedly installed above the connecting piece 103, and the display board 102 is separated from the connecting piece 103 by an insulating part; the light - shielding cover 101 is fixed on the top of the knob body 104 through a snap - fit structure, and the light - shielding cover 101 and the knob body 104 are bonded with waterproof glue. The connecting piece 103 and the display board 102 are of a fixed structure and are not affected by the rotation of any part.
[0022] The knob 100 with digital display and timing control drives the valve stem of the multi - gear valve body 109 to rotate through the knob body 104 to adjust the gear fire power. At the same time, the gear position changer 108 rotates with the valve stem, and the display board 102 displays the corresponding fire power gear on the top of the knob; the timing changer 106 is driven to rotate by the timing adjustment ring 105 to adjust the timing time, and the display board 102 displays the corresponding timing time on the top of the knob. The above two adjustment operations are independent of each other and do not interfere with each other. When the above two adjustment operations occur simultaneously, the display board 102 switches to display the fire power 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 is rotated alone on the knob 100 with digital display and timing control, the gear changes, and the timing adjustment ring 105 will not rotate accordingly; conversely, when the timing adjustment ring 105 is rotated alone, the timing time changes, and the knob body 104 will not rotate accordingly.
[0024] Such as Figure 3As shown in the figure, a double-headed gas stove has two burners on the 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 shifter 108, a timing shifter 106, and a display board 102. The display board 102 displays the fire power level or the timing time of the gas stove. The signals generated by rotating the gear shifter 108 and the timing shifter 106 are sent to the controller 200, and the controller feeds back the signals to the display board 102 to immediately display the corresponding information.
[0025] Furthermore, it also includes a waterproof ring 107. The waterproof ring 107 is installed below the timing shifter 106. The base of the timing shifter 106 is fixedly connected to the waterproof ring 107, and the waterproof ring 107 is also adhered to the upper part of the stove glass panel through waterproof glue.
[0026] When the knob body 104 rotates, the digital display tube in the middle of the display board will display the corresponding gear; when the timing adjustment ring 105 drives the timing shifter 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", after receiving the signal, the controller sends an instruction to the corresponding burner to stop working.
[0027] The light-shielding cover 101 is bonded to the knob body 104 through waterproof glue, and the waterproof ring 107 is bonded to the stove glass panel through waterproof glue, effectively protecting the electronic components in the knob and 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 rotating the knob body 104. The required fire power level can be selected by rotating the knob body 104, and the display board 102 will immediately display the number of this gear. When it is necessary to turn off the gas stove at a set time, the required timing time can be selected by rotating the timing adjustment ring 105 to a specific position, and the display board will immediately display the remaining timing time, and the stove will start working with a countdown. At this time, the timing time and the gear switching are displayed. After the timing is over, the controller 200 can apply a reverse pulse current to the excitation coil of the solenoid valve to generate a magnetic field opposite to that in the working chamber of the solenoid valve, so as to turn off the solenoid valve, cut off the gas, and end the operation of the stove burner. The user can rotate the timing adjustment ring 105 360° to select the timing time, and if it is necessary to change the timing time during the working process, the timing adjustment ring 105 can also be directly rotated, and the operation is very convenient.
