[0020] The technical solution described in this application is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a switch with light applied to a burning appliance comprises a middle shell 4, a light-transmitting upper cover 1 is inserted on the top of the middle shell 4, upper cover wire outlets 2 are provided on both sides of the light-transmitting upper cover 1, and upper wire bayonet 3 is processed on the side of the middle shell 4 corresponding to the upper cover wire outlet 2, the upper wire bayonet 3 on both sides of the middle shell 4 is arranged in pairs and symmetrically on both sides of the lower cover 7, and the upper wire bayonet 3 is used for the wire to pass through and be electrically connected to the spring at the corresponding position.

[0023] A lower cover 7 is inserted at the bottom of the middle shell 4, and shell wire outlets 5 are processed on both sides of the lower part of the middle shell 4. Wire lower bayonet 6 is processed at the position of the lower cover 7 corresponding to the shell wire outlet 5. The wire lower bayonet 6 is arranged in pairs on the side of the lower cover 7 and is symmetrically arranged on both sides of the lower cover 7.

[0024] The light-transmissive upper cover 1 and the middle shell 4 , as well as the middle shell 4 and the lower cover 7 , are connected by corresponding slots 8 and hooks 9 .

[0025] A PCB board 11 is placed in the chamber formed by the light-transmitting upper cover 1 and the middle shell 4, and a lamp bead 12 is connected to the PCB board 11. The PCB board 11 has a circuit structure for lighting the lamp bead 12 after power is turned on. The power supply points of the PCB board 11 are respectively electrically connected to a PCB board static spring 17 and a PCB board dynamic spring 18, and the PCB board static spring 17 and the PCB board dynamic spring 18 are in a normally open state. When the upper spring pressing block 16 moves downward, the upper spring pressing block 16 squeezes the PCB board dynamic spring 18 to move in the direction of the PCB board static spring 17 and contacts with the PCB board static spring 17, so as to realize the power-on of the circuit in the PCB board 11, and then light up the lamp bead 12.

[0026] A lower cover static spring piece 19 and a lower cover dynamic spring piece 20 are arranged in the chamber formed by the lower cover 7 or the middle shell 4. The lower cover static spring piece 19 and the lower cover dynamic spring piece 20 are correspondingly inserted into the card interface at the position. A gap is left between the lower cover static spring piece 19 and the lower cover dynamic spring piece 20 to form a normally open state. When the lower spring piece pressing block 15 moves downward, the lower spring piece pressing block 15 can squeeze the lower cover dynamic spring piece 20 to move in the direction of the lower cover static spring piece 19 and contact the lower cover static spring piece 19, thereby realizing the conduction of the burner switch.

[0027] The lower spring block 15 and the upper spring block 16 are both integrally arranged on the push rod slider 14. The push rod slider 14 is located inside the push rod slideway 13 and slides along the push rod slideway 13. The push rod slider 14 is integrally arranged with the linkage push rod 10. When the operator presses the linkage push rod 10 downward, the linkage push rod 10 drives the lower spring block 15 and the upper spring block 16 to move downward through the push rod slider 14.

[0028] The push rod slideway 13 is located on the light-transmitting upper cover 1 , the middle shell 4 , and the lower cover 7 , and a reset spring (not shown in the figure) is arranged at the bottom of the push rod slideway 13 to realize the reset of the linkage push rod 10 .

[0029] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0030] like Figures 4 to 5 As shown, and see Figures 1 to 3In the present application, the middle shell 4 includes a top end and a bottom end, and a step structure is formed between the top end and the bottom end, and the middle shell 4 is inserted into the interior of the light-transmitting upper cover 1 through the top end, and the light-transmitting upper cover 1 is made of a transparent or translucent material. After the middle shell 4 is inserted into the light-transmitting upper cover 1, the hook 9 on the middle shell 4 is engaged with the corresponding slot 8 on the light-transmitting upper cover 1. At this time, the light-transmitting upper cover 1 and the middle shell 4 form a chamber for accommodating the PCB board 11, and the PCB board 11 is placed on the middle shell 4 and can be limited in the middle shell 4 by screws or hooks.

[0031] The bottom of the PCB board 11 may be welded with a lower spring block 15 and an upper spring block 16, and a normally open contact is formed between the lower spring block 15 and the upper spring block 16. When the lower spring block 15 and the upper spring block 16 are in contact, the external wire can supply power to the PCB board 11, so that the PCB board 11 can light up the lamp bead 12 through the circuit structure. The lamp bead 12 can be an LED lamp bead.

[0032] A lower cover 7 is inserted into the bottom opening of the middle shell 4. After the lower cover 7 is inserted into the bottom end of the middle shell 4, the hook 9 of the lower cover 7 cooperates with the slot 8 on the middle shell 4 to achieve a snap connection.

[0033] The lower cover 7 and the middle shell 4 form a chamber for accommodating the lower cover static reed 19 and the lower cover moving reed 20. The lower cover static reed 19 and the lower cover moving reed 20 form a normally open contact in the chamber. When the lower cover static reed 19 and the lower cover moving reed 20 are in contact, the burner switch can be turned on, thereby realizing the ignition operation.

[0034] In the above process, referring to Example 1, the lower spring sheet pressure block 15 and the upper spring sheet pressure block 16 for realizing the above-mentioned spring conduction are distributed up and down on the push rod slider 14, and the push rod slider 14 moves integrally with the linkage push rod 10. In the process of the push rod slider 14 moving along the push rod slide 13, the spring conduction in the above-mentioned normally open contact state can be realized at the same time, that is, the lamp bead 12 is lit and the appliance switch is ignited synchronously.

[0035] In the present application, by setting up the middle shell 4, it is possible to achieve effective connection with the light-transmitting upper cover 1 and the lower cover 7, reduce the complexity of the structure, and achieve convenience in installation. Most of the structures described in the present application can be fixed by simple connection methods, such as snap-in, plug-in, etc., to facilitate the improvement of installation efficiency.

[0036] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
