[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The utility model embodiment provides a crescent-shaped luminous knob, such as Figure 1 and Figure 2 As shown, the crescent-shaped luminous knob includes a knob body 1, a circuit board 2 and a bottom cover 3, wherein the knob body 1 includes a light-transmitting structure 11 arranged on the top surface of the knob body 1 and a connecting groove 14 ( Figure 3 The cross-sectional shape of the connection groove 14 is D-shaped, which is used to achieve plug-in connection with the gas valve stem on the stove. The circuit board 2 is connected to the knob body 1 by screws, and a light-emitting element 21 and a Hall switch 22 ( Figure 4), the light emitting element 21 is electrically connected to the Hall switch 22, wherein the light emitting element 21 is preferably an LED lamp bead, and by loading LED lamp beads of different colors, the knob can emit lights of different colors, and the lights emitted by the lamp beads can pass through the light-transmitting structure 11. The bottom cover 3 is detachably connected to the cooker by screws, and after the connection, the bottom cover 3 covers the bottom surface of the knob body 1, and the gas valve stem on the cooker passes through the bottom cover 3 and the circuit board 2 in sequence, and then is detachably connected to the knob body 1.

[0023] Further, in this embodiment, the light-transmitting structure 11 is crescent-shaped and is disposed along the top edge of the knob body 1. In other embodiments, the light-transmitting structure 11 may also be in other shapes, such as circular, rectangular or triangular.

[0024] Furthermore, a zero mark 12 is provided on the upper surface of the knob body 1, and the zero mark 12 can facilitate the user to intuitively see the gear position of the knob at present. The zero mark is light-transmissive.

[0025] like Figure 3 As shown, the overall shape of the knob body 1 is cylindrical, and a battery slot 13, a connecting slot 14 and a fixing slot 15 are arranged inside along the height, wherein the connecting slot 14 is arranged at the center of the knob body 1, and is used to connect with the gas valve stem on the cooker; the fixing slot 15 is used to connect with the circuit board 2, and there are four fixing slots 15, and multiple fixing slots 15 are arranged around the connecting slot 14, and the outer wall of each fixing slot 15 is connected to the inner wall of the knob body 1 through a rib structure to reinforce the structural stability of the connecting slot 15; there are two battery slots 13, which are used to place cylindrical batteries to power the crescent-shaped luminous knob.

[0026] Furthermore, the central axes of the battery slot 13 , the connecting slot 14 and the fixing slot 15 are parallel to each other.

[0027] like Figure 4 As shown, the circuit board 2 is a disc-shaped structure, on which a light-emitting element 21 and a Hall switch 22 are arranged. There are two light-emitting elements 21, and the Hall switch 22 is used to control the power on and off of the knob. Specifically, the Hall switch 22 needs to be used in conjunction with the electromagnet. When the Hall switch 22 is closest to the electromagnet, the Hall switch 22 is at the origin, the circuit is disconnected, and the light-emitting element 21 does not light up; when the user turns the knob, the Hall switch 22 starts to move away from the electromagnet, at which time the circuit is turned on and the light-emitting element 21 starts to light up.

[0028] Furthermore, the circuit board 2 is also provided with a battery hole 23 and a connection hole 24, which are arranged around the first through hole in the middle of the circuit board 2. The first through hole is provided so that the gas valve stem of the cooker can pass through the circuit board 2. The two battery holes 23 are electrically connected through the battery sheet. Specifically, the connection between the battery holes 23 is in parallel and isolated by a diode to prevent the two batteries from discharging each other. The connection hole 24 is used in conjunction with the connection slot 15 to connect the circuit board 2 to the knob body 1. The position and number of the connection holes 24 correspond to the connection slots 15 one by one.

[0029] like Figure 5 As shown, the bottom cover 3 includes a second through hole 31, a magnet position 32 and a connection hole 33. The second through hole 31 is located in the middle of the bottom cover 3. The second through hole 31 is provided so that the gas valve stem of the cooker can pass through the bottom cover 3. The magnet position 32 is used to place the electromagnet, and when the knob is at the zero position (i.e., the initial position), its position is directly below the Hall switch 22.

[0030] Furthermore, the connection holes 33 are used to fix the bottom cover 3 to the cooker by screws.

[0031] Furthermore, the utility model also provides a cooker, which comprises the above-mentioned crescent-shaped luminous knob.

[0032] The method of using the utility model is as follows: first, fix the bottom cover on the stove, then install the battery into the battery slot of the knob body, and then insert the connection slot of the knob body into the gas valve stem to complete the installation of the knob. When using, press the knob, wait for the stove to light up, twist the knob, and the knob will start to glow. The user can

[0033] The utility model has the following beneficial effects: by adding a light-emitting element to the existing knob, the knob will emit bright light when in use, which is helpful for the user to observe the fire power level of the stove through the knob in an environment with insufficient lighting.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
