[0038] like Figures 1 to 4As shown, this embodiment provides a gas cooker knob, which can reduce the post-processing steps of the gas cooker panel 100, reduce labor costs, and improve the production efficiency of the gas cooker. The gas cooker knob includes a knob housing 1 and a light emitting component 2.
[0039] Among them, see Figure 1 and Figure 2 The knob housing 1 is provided with a first light-transmitting area 111 and a plurality of second light-transmitting areas (not shown), and the light-emitting component 2 is provided in the knob housing 1. The light energy emitted by the light-emitting component 2 is projected onto the panel 100 of the gas cooker via the first light-transmitting area 111, so as to form a current fire power cursor 13 on the panel 100. At the same time, the light energy emitted by the light-emitting component 2 is projected onto the panel 100 via the plurality of second light-transmitting areas, so as to form a plurality of fire power indicators 14 on the panel 100. The plurality of fire power indicators 14 correspond to the plurality of fire power levels of the gas cooker one by one, and the current fire power cursor 13 can be aligned with any fire power indicator 14 to indicate the current fire power level of the gas cooker.
[0040] The gas stove knob provided in this embodiment, when the gas stove knob is turned to ignite, the light energy emitted by the light-emitting component 2 is projected on the panel 100 of the gas stove through the first light-transmitting area 111 to form a current fire power cursor 13, and at the same time, the light emitted by the light-emitting component 2 is projected on the panel 100 through multiple second light-transmitting areas to form multiple fire power indicators 14. When the gas stove knob is rotated to the point where the current fire power cursor 13 is aligned with a certain fire power indicator 14, the fire power level indicated by the fire power indicator 14 is the current fire power level of the gas stove. This arrangement allows the user to intuitively know the current fire power value of the gas stove, which is convenient for adjusting the fire power. The gas stove knob indicates the fire power level of the gas stove by light projection, and there is no need to screen-print the fire power mark on the panel 100 of the gas stove, nor is there a need to perform a silk-printing quality inspection process, which simplifies the post-processing process of the panel 100, can reduce the production cost of the gas stove, and improve production efficiency.
[0041] In other embodiments, multiple fire power identification marks can also be directly set on the panel 100 of the gas stove. For example, multiple fire power identification marks can be processed on the panel 100 by silk screen hollowing. When the current fire power cursor 13 is projected to align with any fire power identification mark, the fire power level corresponding to the fire power identification mark is the current fire power level of the gas stove.

The light-emitting component 22 is electrically connected to the electric control board 21, and the electric control board 21 is used to control the opening and closing of the light-emitting component 22. The control circuit and control program of the light-emitting component 22 are arranged on the electric control board 21. When the knob is turned, the electric control board 21 is powered on and controls the light-emitting component 22 to light up according to the control program, so that the light passes through the first light-transmitting area 111 to project the current fire power cursor 13 on the panel 100 of the gas cooker, and at the same time, the light passes through the multiple second light-transmitting areas to project multiple fire power indicators 14 on the panel 100.
[0043] In this embodiment, Figure 1 As shown, the electric control board 21 is annular, and the hole in the middle of the annular shape is used to pass the valve stem of the fire regulating valve of the gas cooker. Further, the light-emitting component 22 is an LED light strip attached to the inner wall of the knob housing 1. When the LED light strip is powered on and lit, the first light-transmitting area 111 and the plurality of second light-transmitting areas can transmit light.
[0044] In other embodiments, a control program may be set on the electric control board 21 to control the lighting mode of the light emitting component 22. For example, the light emitting component 22 may light up in white, yellow, red, etc. When the fire power level is in the low level range, the light emitting component 22 lights up in white, when the fire power level is in the middle level range, the light emitting component 22 lights up in yellow, and when the fire power level is in the high level range, the light emitting component 22 lights up in red. In this way, the user can be prompted to the current fire power of the gas cooker by the color of the light, and the effect is more intuitive.
[0045] Optionally, see Figure 3 and Figure 4 The knob housing 1 is provided with a display area 121, which is used to display the fire power level corresponding to the current fire power cursor 13.

Specifically, the plurality of LED lamp beads are electrically connected to the electric control board 21, and the electric control board 21 controls the display position and display quantity of the LED lamp beads according to the firepower level indicated by the firepower indicator 14 corresponding to the current firepower cursor 13, so that the display area 121 displays the number corresponding to the current firepower level. Alternatively, a color film or a color screen may be provided in the display area 121, and a plurality of first display light spots 1211 may be presented on the color film or the color screen. The color film / color screen is electrically connected to the electric control board 21, and the electric control board 21 controls the color film / color screen to display the corresponding number according to the firepower level indicated by the firepower indicator 14 corresponding to the current firepower cursor 13.
[0048] Alternatively, a digital tube may be provided in the display area 121, wherein the multiple light emitting diodes of the digital tube correspond to the multiple first display light spots 1211, and when a certain segment on the digital tube is lit, a certain number is displayed to indicate the current fire power level of the gas cooker.
[0049] In a second alternative embodiment, Figure 4 As shown, the display area 121 is provided with a plurality of second display light spots 1212, which are distributed in a ring shape, and the plurality of second display light spots 1212 correspond one to one with the plurality of fire power levels of the gas cooker, and the number of the second display light spots 1212 that are lit is used to indicate the current fire power level of the gas cooker. That is, the current fire power level of the gas cooker can be known by observing the number of the second display light spots 1212 that are lit.
[0050] Exemplarily, a plurality of LED lamp beads may be provided in the display area 121, the plurality of LED lamp beads correspond to a plurality of second display light spots 1212, the plurality of LED lamp beads are electrically connected to the electric control board 21, and the electric control board 21 controls the display quantity of the LED lamp beads according to the firepower level indicated by the firepower indicator 14 corresponding to the current firepower cursor 13, so as to indicate the current firepower level. Alternatively, a color film or color screen may be provided in the display area 121, the color film / color screen has a plurality of second display light spots 1212, the color film / color screen is electrically connected to the electric control board 21, and the electric control board 21 controls the color film / color screen to light up a corresponding number of second display light spots 1212 according to the firepower level indicated by the firepower indicator 14 corresponding to the current firepower cursor 13.
[0051] In a third optional implementation, a plurality of first display light spots 1211 and a plurality of second display light spots 1212 may also be simultaneously arranged in the display area 121 , so that the display area 121 simultaneously displays numbers and a corresponding number of second display light spots 1212 .
[0052] Optionally, see Figure 1 and Figure 2 A logo 124 may also be provided in the display area 121 , and the logo 124 may increase brand recognition and improve the aesthetics of the gas stove knob.
[0053] Optionally, see Figure 1 The knob housing 1 includes a bottom shell 11 and an upper cover 12 that are interlocked. A receiving cavity for accommodating the light-emitting component 2 is formed between the bottom shell 11 and the upper cover 12. The first light-transmitting area 111 and the second light-transmitting area are both located on the outer circumference of the bottom shell 11, and the display area 121 is located on the top surface of the upper cover 12. The knob housing 1 is designed as a split bottom shell 11 and upper cover 12 structure, which is convenient for installing and maintaining the light-emitting component 2. The first light-transmitting area 111 and the second light-transmitting area are both arranged on the outer circumference of the bottom shell 11, so that the current firepower cursor 13 and the firepower indicator 14 can be projected on the outer circle of the gas stove knob for easy observation. The display area 121 is arranged on the top surface of the upper cover 12, which is convenient for users to view the specific firepower gear.
[0054] In this embodiment, the first light-transmitting area 111 is in the shape of a vertical bar, and the light transmitted through the first light-transmitting area 111 is projected on the panel 100 to form an annular aperture, which is the current firepower cursor 13. The second light-transmitting area is a circular dot, and the light transmitted through the second light-transmitting area is projected on the panel 100 to form a circular light dot, and multiple circular light dots are multiple firepower indicators 14.
[0055] Optionally, see Figure 2 , Figure 3 and Figure 4 The outer wall of the bottom shell 11 is provided with a circle of anti-skid area 112 along the circumferential direction, and an anti-skid pad or a plurality of anti-skid protrusions are provided in the anti-skid area 112. Such a configuration can increase the friction between the gas stove knob and the user's hand, making the screwing operation more convenient and labor-saving. Exemplarily, the anti-skid pad can be a rubber pad or a frosted plastic. Alternatively, the entire anti-skid area 112 is made of acrylic material with a concave-convex structure.
[0056] In this embodiment, the first light-transmitting area 111 and the second light-transmitting area are both located in the anti-slip area 112 , which facilitates the processing of the first light-transmitting area 111 and the second light-transmitting area.
