Description

Technical Field

[0001] The utility model relates to the technical field of stoves, and more specifically to a stove knob. Background Art

[0002] Existing stove knobs are mainly divided into mechanical knobs and smart knobs. Mechanical knobs can only be used to adjust the fire power and have a single function, making it difficult to adapt to the diversified functional needs of stoves. Smart knobs have many extended functions, and their power supply modes are mostly wireless power supply or built-in battery solutions. They cannot retain the tactile feedback of mechanical knobs such as pressing to ignite, shifting gears to adjust fire power, etc., and the human-computer interaction experience is poor. If motor knobs are used, the cost is too high. For example, the Chinese patent authorization announcement number is CN219530939U, which discloses a stove knob and a knob control system. The stove knob includes a knob body, a switch, and a display panel. The knob body has a cavity running through it; the switch is arranged in the cavity; the display panel cover is arranged on one side of the knob body for sealing the cavity, and the display panel includes a one-key stir-fry button and a panel communication module connected to the one-key stir-fry button; wherein the switch is located on the lower side of the one-key stir-fry button so as to move downward with the one-key stir-fry button when the one-key stir-fry button is pressed. The one-key stir-fry button is used to manually control the opening and closing of stir-frying and display the stir-frying firepower status. The stove knob is equipped with a switch in the knob, which is connected to the controller. The one-key stir-frying function is activated by pressing the switch. At the same time, the knob has the functions of stir-frying firepower status display, high fire display, and low fire display.
