[0013] Preferably, the lampshade is transparent or semi-transparent; the advantage is that the color of the indicator light can be displayed through the lampshade, thus allowing for a direct assessment of the barbecue's status.

[0014] Compared with existing technologies, the advantages of this utility model are that the lampshade can both display the status of the indicator light and function as a button, resulting in better overall design, smoother user pressing, and an optimized user experience. It also avoids the problem of numerous components in traditional designs, reducing the risk of product jamming due to the coordination of multiple parts. The included reset spring effectively drives the lampshade upward, ensuring reliable separation after pressing, and increases the force required to trigger the switch, thus preventing accidental activation of the switch and ensuring reliable operation.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] As attached Figure 1-7The barbecue grill shown includes a self-contained switch to prevent accidental activation, comprising a grill body 1 and a switch assembly 2. The grill body 1 includes a hinged upper shell 1.1 and a lower base 1.2. The switch assembly 2 includes a lampshade 2.1, a return spring 2.2, and a PCB board 2.3 integrating a switch 2.4 and an indicator light 2.5. The PCB board 2.3 is fixed to the upper shell 1.1. The upper shell 1.1 has a mounting hole 1.11, within which the switch is located. The lampshade 2.1 is vertically movable within the mounting hole 1.11. When the lampshade 2.1 is subjected to external force, it can press down to activate the switch. The return spring 2.2, located within the upper shell 1.1, is used to push the lampshade 2.1 upwards. The lampshade 2.1 can display the status of the indicator light 2.5 and also function as a button, offering better overall design, smoother user pressing, and an optimized user experience. It also avoids the problem of numerous components in traditional designs, reducing the risk of product jamming due to the coordination of multiple components. Meanwhile, the reset spring 2.2 can effectively drive the lampshade 2.1 to move upward, that is, reliably separate after being pressed, and increase the force of the lampshade 2.1 to trigger the switch, thereby preventing the lampshade 2.1 from being accidentally touched, which would lead to the accidental triggering of the switch 2.4, thus ensuring the reliability of use.

[0026] Based on the above, the upper housing 1.1 is provided with a limiting ring 1.3 located around the mounting hole 1.11. The lampshade 2.1 is movably disposed within the limiting ring 1.3, and the lampshade 2.1 is provided with a limiting block 2.12 located below the limiting ring 1.3. Preferably, both sides of the lampshade 2.1 are provided with connecting posts 2.11, and the bottom of each connecting post 2.11 is provided with a limiting block 2.12. More specifically, both ends of the same side of the lampshade 2.1 are provided with connecting posts 2.11. The cooperation of the limiting ring 1.3 and the limiting block 2.12 can limit the lampshade 2.1, preventing it from slipping upwards. The connecting posts 2.11 and the limiting blocks 2.12 on both sides of the lampshade 2.1 can ensure the stability of the lampshade 2.1's movement and prevent it from slipping.

[0027] It is worth mentioning that the inner wall of the limiting ring 1.3 is provided with a limiting platform 1.31, and the lamp cover 2.1 is located above the limiting platform 1.31. The limiting platform 1.31 can restrict the downward movement of the lamp cover 2.1, which not only ensures the reliability of the switch triggering, but also avoids excessive pressure on the switch, reduces the impact and collision on the switch, and improves its service life.

[0028] The PCB board 2.3 of this design is equipped with a fixing platform 2.31. The switch is located on the upper side of the fixing platform 2.31, and the return spring 2.2 is sleeved on the outside of the switch, with both ends abutting against the lampshade 2.1 and the fixing platform 2.31 respectively. More specifically, a limit post 2.13 is provided at the lower part of the middle of the lampshade 2.1, and the top of the return spring 2.2 is sleeved on the outside of the limit post 2.13. The limit post 2.13 ensures the stability of the return spring 2.2 during operation and prevents displacement, thereby ensuring the stability of the reset drive of the lampshade 2.1.

[0029] To improve the ease of installation of the PCB board 2.3, the upper housing 1.1 is provided with fixing posts 1.12 located at both ends of the PCB board 2.3, and the two ends of the PCB board 2.3 are fixed to the corresponding fixing posts 1.12 by screws.

[0030] The indicator light 2.5 of this utility model includes multiple LEDs of different colors, all of which are fixed on the PCB board 2.3. By setting LEDs of different colors, the status of the barbecue can be displayed in different colors, such as the heating status and the power-on status of the barbecue, thus improving intuitiveness.

[0031] It is worth mentioning that the lampshade 2.1 in this design is transparent or semi-transparent, and the color of the indicator light 2.5 can be directly displayed through the lampshade 2.1, so as to judge the status of the barbecue machine.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
