[0043] Reference Figures 1 to 8 In one embodiment of the utility model, a knob with a timing function is provided, which includes a base 100, a timing assembly 200 and a rotary cover 300. The base 100 is provided with a mounting hole 110 for the valve stem 410 to pass through. The timing assembly 200 is fixedly mounted on the base 100 and is located above the base 100. The upper end of the timing assembly 200 is provided with a display device 210 electrically connected to the timing assembly 200, and the lower part of the timing assembly 200 is provided with a clearance groove 120 connected to the mounting hole 110. The rotary cover 300 is movably sleeved on the outer periphery of the display device 210, and the rotary cover 300 is connected with a connecting rod 310, which is movably inserted into the clearance groove 120, and the connecting rod 310 has a connecting portion 311 for connecting the valve stem 410. Among them, the rotary cover 300 can rotate relative to the display device 210 and drive the connecting rod 310 to rotate along the clearance groove 120, and the connecting rod 310 can drive the valve stem 410 to rotate to adjust the firepower.

[0044] By adopting the knob with timing function of the new embodiment of the present invention, when installing, the base 100 of the knob is fixedly installed on the installation platform, and the valve stem 410 of the gas regulating valve 400 is inserted into the installation hole 110 of the base 100 and connected to the connecting portion 311 on the connecting rod 310, and the installation is simple and convenient. When in use, the rotary cover 300 is twisted, and the rotary cover 300 can rotate relative to the display device 210 and drive the connecting rod 310 to rotate along the yielding groove 120, and the connecting rod 310 can drive the valve stem 410 to rotate, so that the firepower can be adjusted. During the entire adjustment process, the display device 210 remains stationary relative to the base 100 and does not rotate synchronously with the rotary cover 300, thereby facilitating the user to accurately identify the information displayed by the display device 210, and facilitating the user to use.

[0045] It is understandable that the display device 210 may be a display, a digital tube or other devices with display functions, and the present invention does not make any specific limitation on this.

[0046] Reference Figures 1 to 8 In some embodiments, in the up-down direction, the width of the clearance groove 120 is greater than the height of the connecting rod 310, the knob can move in the up-down direction relative to the display device 210 and drive the connecting rod 310 to move up-down in the clearance groove 120, and the connecting rod 310 can drive the valve stem 410 to move in the up-down direction.

[0047] Since the gas regulating valve 400 usually needs to first press the valve stem 410 down to the set position during use, and then the valve core can be driven to rotate to adjust the firepower, therefore, by adopting the knob with a timing function in the embodiment of the utility model, the width of the clearance groove 120 is greater than the height of the connecting rod 310 in the up-down direction, so that the connecting rod 310 can move in the up-down direction in the clearance groove 120. Specifically, when in use, the rotary cover 300 is pressed down, the rotary cover 300 can move downward relative to the display and drive the connecting rod 310 to move downward in the clearance groove 120, and the connecting rod 310 can drive the valve stem 410 to move downward, and then the knob is turned, the rotary cover 300 can rotate relative to the display device 210 and drive the connecting rod 310 to rotate along the clearance groove 120, and the connecting rod 310 can drive the valve stem 410 to rotate, so that the firepower can be adjusted. During the entire adjustment process, whether the rotary cover 300 is twisted or moved up and down, the display device 210 always remains stationary relative to the base 100 and does not move or rotate synchronously with the rotary cover 300, thereby making it easier for users to accurately identify the information displayed on the display device 210 and facilitating user use.

[0048] Reference Figures 1 to 8 In some embodiments, the base 100 is provided with an upwardly protruding support portion 130 , the timing assembly 200 is mounted on the support portion 130 and spaced apart from the base 100 , and the clearance groove 120 is located between the timing assembly 200 and the base 100 .

[0049] By adopting the above structure, the timing assembly 200 is installed on the support part 130, so that the timing assembly 200 is located above the base 100 and is arranged at a distance from the base 100, and the clearance groove 120 is located between the timing assembly 200 and the base 100. Therefore, the rotary cover 300 can be sleeved on the outer periphery of the timing assembly 200 and the connecting rod 310 can be inserted into the clearance groove 120. The structure is simple and easy to install.

[0050] Reference Figures 1 to 8 In some embodiments, the side wall of the support portion 130 has an outwardly extending mounting portion 140, the timing assembly 200 is mounted on the mounting portion 140, the mounting portion 140 is located above the base 100 and is spaced apart from the base 100, and the clearance groove 120 is formed by the gap between the mounting portion 140 and the base 100.

[0051] In the above structure, by providing the mounting portion 140 extending outwardly relative to the supporting portion 130 , the mounting area of ​​the timing assembly 200 can be increased, so that the mounting of the timing assembly 200 is more firm and reliable.

[0052] It is understandable that the mounting portion 140 may be specifically arranged to extend along the circumference of the mounting hole 110 , which not only facilitates the installation of the timing assembly 200 , but also avoids interference between the valve stem 410 in the mounting hole 110 and the mounting portion 140 .

[0053] It is understandable that, referring to Figures 1 to 8 In some embodiments, the support portion 130, the mounting portion 140 and the base 100 are an integrally formed structure, which can make the production and processing of the knob simpler and more convenient, and reduce the assembly process of the knob.

[0056] It should be noted that the protection screen 250 specifically refers to a transparent or light-transmitting device, such as a protective lens, etc. It is understandable that the protection screen 250 specifically can be a touch screen, so that the user can input the timing instruction by touch.

[0057] It is understandable that, in order to facilitate the installation between the protection screen 250 and the bottom shell 240, the protection screen 250 may include a bracket and a lens, and the lens is disposed in the bracket and connected to the bottom shell 240 through the bracket.

[0058] It can be understood that the bottom shell 240 is installed on the support part 130.

The structure is simple, which facilitates the production and processing of the protective screen 250 and the bottom shell 240, and makes the installation and assembly between the protective screen 250 and the bottom shell 240 simple and convenient.

[0063] It can be understood that the first clamping portion 251 is provided with a clamping slot 252, and the second clamping portion 241 can be mutually clamped with the corresponding clamping slot 252. Figures 1 to 11 In some embodiments, the second clamping portion 241 may be provided with a clamping slot 252, and the first clamping portion 251 may be clamped with the corresponding clamping slot 252, which is not specifically limited in the present invention.

The first clamping portion 251 can be inserted downward into the slot 242 and the first clamping portion 251 and the second clamping portion 241 are clamped with each other.

[0065] In the above structure, by providing a slot 242 corresponding to the first clamping portion 251 on the inner wall of the bottom shell 240, it is possible to facilitate the positioning of the installation between the protective screen 250 and the bottom shell 240, so that the first clamping portion 251 can be more accurately engaged with the corresponding second clamping portion 241 after being inserted into the slot 242, making the installation and assembly between the protective screen 250 and the bottom shell 240 simple and convenient. In addition, by adopting the structure of the embodiment of the utility model, the first clamping portion 251 can not only be engaged with the corresponding second clamping portion 241, but also be engaged with the corresponding slot 242 for insertion and positioning, without the need to provide an additional positioning structure between the protective screen 250 and the bottom shell 240, the first clamping portion 251 can simultaneously play the role of installation and positioning, killing two birds with one stone, thereby making the connection structure between the bottom shell 240 and the protective screen 250 simpler.
