Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, specifically to a knob with an indicator light for a gas stove. Background Technology

[0002] Most conventional, low-end gas stoves (such as barbecue grills and pizza ovens) do not have illuminated knobs, while some high-end gas stoves are equipped with knob lighting systems. Knobs are used to control the gas valve's on / off state and adjust the gas flow.

[0003] Among them, gas stoves with knob lighting systems must have corresponding power supply, control devices and other electrical components installed on the stove body. In other words, the lighting system is integrated and installed on the stove body. This results in different molds for low-end and high-end gas stoves. Low-end gas stoves are difficult to upgrade later, and consumers cannot change them at will according to their own needs. Utility Model Content

[0004] The purpose of this invention is to provide a light-up knob for a gas stove that allows the lighting system to be upgraded without the need for pre-installed electrical devices.

[0005] The purpose of this utility model is achieved as follows.

[0006] A lighted knob for a gas stove includes a knob body, a base on the back of the knob body, the base and the knob body being connected and fixed together, forming a cavity. An electrically connected lamp panel, battery, and switch are located within the cavity. The battery powers the lamp panel, and the switch controls the LEDs on the lamp panel. The knob body and / or the base have a light-transmitting area. The bottom of the knob body has a slot, and the base has a first clearance hole corresponding to the slot. The front of the knob body has a through hole communicating with the cavity. The switch has a pressing element and a resetting element. The outer end of the pressing element extends out of the through hole to form a pressing part, and the inner end of the pressing element is limited to movement within the cavity. The resetting element has a tendency to push the pressing element outwards from the through hole.

[0007] Furthermore, the lamp beads are located on the side of the lamp panel facing the base, and the base is made of transparent material, forming the light-transmitting area. The light from the lamp beads is refracted by the base to illuminate the knob.

[0008] Furthermore, a first recess is provided on the back of the knob body, and a second recess is provided on the front of the base. After the base and the knob body are connected, the first and second recesses constitute the receiving cavity, and the lamp plate is disposed in the second recess. This helps to reduce the overall size of the knob. The second recess facilitates the lamp plate to guide light along the circumference of the base.

[0009] Furthermore, a connecting post is provided on the back of the knob body, and the connecting post has the slot along its axis. The light panel has a second clearance hole, and the connecting post passes through the second clearance hole and abuts against the bottom surface of the second recess. The first clearance hole communicates with the bottom surface of the second recess, and the slot and the first clearance hole are aligned. This satisfies the normal function of the knob in controlling the gas valve.

[0010] Furthermore, a connecting stud is provided on the bottom surface of the second cavity. The lamp board and the connecting stud are connected and fixed by screws. The lamp beads on the lamp board face the bottom surface of the second cavity, and a gap is left between the lamp beads and the bottom surface of the second cavity. The gap prevents the base from damaging the lamp beads.

[0011] Furthermore, a fixing plate is provided in the accommodating cavity, and a first mounting cavity is formed between the fixing plate and the knob body. The switch, pressing element and reset element are placed in the first mounting cavity. A second mounting cavity is formed between the fixing plate and the knob body. The lamp plate is placed in the second mounting cavity. The fixing plate forms a battery compartment. The battery is fixed in the battery compartment. The battery compartment is provided with a cover facing the second mounting cavity.

[0012] Furthermore, the switch and knob bodies are connected and fixed. The actuating end of the switch faces the through hole, and the inner end of the through hole has a first stepped portion. The inner end of the pressing component has a second stepped portion circumferentially, and the inner end of the pressing component has a positioning groove. The resetting component is a spring, with one end of the spring abutting against the switch and the other end of the spring inserted into the positioning groove and abutting against the pressing component. The spring force pushes the outer end of the pressing component to extend out of the through hole until the first stepped portion and the second stepped portion abut against each other and are limited, at which point the pressing component disengages from the actuating end of the switch. The pressing component cannot disengage from the knob body, and the pressing action of the pressing component is smooth and reliable.

[0013] Furthermore, the positioning groove extends towards the actuating end to form an abutment portion, which abuts against or is close to the actuating end. The pressing element can sensitively actuate the switch.

[0014] Furthermore, the lamp board is equipped with a control chip, and the lamp board is equipped with at least two colors of LED beads. The switch and the control chip work together to control the lamp board to turn on and turn on the LED beads of different colors in a preset order, and to turn off the lamp board.

[0015] This invention integrates a lighting system into the knob, allowing consumers to easily upgrade or replace the original ordinary knobs on their ovens. The lighting system can be controlled independently to meet usage needs. The overall design is small in size, stable in structure, reliable, and has a long service life. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1, see Figure 1-3 As shown, a gas stove knob with an indicator light includes a knob body 1, a base 2, an indicator light 3, a battery 4, a switch 5, a fixing plate 6, a pressing component 7, and a resetting component 8.

[0021] The knob body 1 has a first recess 11 on its back side, a connecting post 12 inside the first recess 11, and a slot 13 axially provided on the connecting post 12. The knob body 1 has a through hole 14 on its front side, which connects to the first recess 11. The inner end of the through hole 14 has a first step portion 15. Preferably, the knob body 1 has an inner recess 16 on its front side, and the outer end of the through hole 14 is placed on the bottom surface of the inner recess 16.

[0022] The base 2 has a second recess 21 on its front side, and a connecting stud 22 on the bottom surface of the second recess 21. After the base 2 and the knob body 1 are connected, the first recess 11 and the second recess 21 form a receiving cavity 9. The base 2 is made of transparent material and forms a light-transmitting area.

[0023] The fixing plate 6 and the knob body 1 are connected and fixed, that is, the fixing plate 6 divides the accommodating cavity 9, and the fixing plate 6 and the knob body 1 form a first mounting cavity 91. The switch 5, the pressing part 7 and the resetting part 8 are placed in the first mounting cavity 91. The fixing plate 6 and the knob body 1 form a second mounting cavity 92. The lamp plate 3 is placed in the second mounting cavity 92. The fixing plate 6 forms a battery compartment 61. The battery 4 is fixed in the battery compartment 61. The battery compartment 61 is provided with a cover 62 facing the second mounting cavity 92.

[0024] The switch 5 and the knob body 1 are connected and fixed, with the actuating end 51 of the switch 5 facing the through hole 14. The inner end of the pressing member 7 is limited to the accommodating cavity 9. Specifically, the inner end of the pressing member 7 has a second step portion 71 circumferentially provided, and the inner end of the pressing member 7 has a positioning groove 72. The reset member 8 is a spring, with one end of the spring abutting against the switch 5, and the other end of the spring inserting into the positioning groove 72 and abutting against the pressing member 7. The reset member 8 has a tendency to push the pressing member 7 out of the through hole 14. The spring force pushes the outer end of the pressing member 7 to extend out of the through hole 14 until the first step portion 15 and the second step portion 71 abut and limit it, and the pressing member 7 disengages from the actuating end 51 of the pressing switch 5. The positioning groove 72 extends towards the actuating end 51 with an abutting portion 73, which abuts against or is close to the actuating end 51. Preferably, the outer end of the pressing member 7 extends through the through hole 14 to form a pressing part 74, and the pressing part 74 is placed in the recessed part 16 to avoid the pressing member 7 being easily accidentally touched.

[0025] The lamp plate 3 and the connecting stud 22 are fixed in the second cavity 21 by screws. The lamp plate 3 has lamp beads 31 on the side facing the base 2, that is, the lamp beads 31 on the lamp plate 3 face the bottom surface of the second cavity 21. A gap 33 is left between the lamp beads 31 and the bottom surface of the second cavity 21. The bottom surface of the second cavity 21 has a first clearance hole 23, and the lamp plate 3 has a second clearance hole 34. The connecting stud 12 passes through the second clearance hole 34 and abuts against the bottom surface of the second cavity 21. The first clearance hole 23 communicates with the bottom surface of the second cavity 21, and the slot 13 is aligned with the first clearance hole 23.

[0026] The lamp board 3, battery 4, and switch 5 are electrically connected. Battery 4 supplies power to lamp board 3, and switch 5 controls the LED beads 31 on lamp board 3. Switch 5 is a self-resetting push-button switch, which is existing technology. Battery 4 is a 4LR44 battery.

[0027] Preferably, a control chip 32 is provided on the front of the lamp panel 3, and the lamp panel 3 has three colors of LED beads 31 (such as white LED beads 31, blue LED beads 31, and red LED beads 31). The switch 5 and the control chip 32 work together to control the lamp panel 3 to turn on and off in a preset sequence, illuminating the LED beads 31 of different colors sequentially. For example, when the pressing part presses the switch 5 for the first time, the switch 5 sends a signal to the control chip 32, and the control chip 32 controls the lamp panel 3 to illuminate only the white LED beads 31. When the pressing part presses the switch 5 for the second time, the switch 5 sends a signal to the control chip 32, and the control chip 32 controls the lamp panel 3 to illuminate only the blue LED beads 31. When the pressing part presses the switch 5 for the third time, the switch 5 sends a signal to the control chip 32, and the control chip 32 controls the lamp panel 3 to illuminate only the red LED beads 31. When the pressing part presses the switch 5 for the fourth time, the control chip 32 controls the lamp beads 31 to turn off. This cycle of control over the LED beads 31 continues periodically. The light emitted by the LED beads 31 is emitted circumferentially through the base 2.

[0028] The illuminated knob of this invention aligns with the rotating shaft of the gas valve on the furnace body via a first clearance hole 23. The rotating shaft passes through the first clearance hole 23 and the second clearance hole 34 and is inserted into the slot 13. The rotating shaft and the slot 13 are not circularly fitted. The overall rotation of the illuminated knob drives the rotating shaft to rotate. The operation of replacing the illuminated knob is simple and easy, making it convenient for users.
