For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Reference Figure 1 to Figure 2 According to the first aspect of the present invention, a double-layer knob includes a base 100, a knob assembly 200 and a display module 300. The knob assembly 200 includes a first knob 210 and a second knob 220 that can rotate independently relative to the base 100. The rotation axes of the first knob 210 and the second knob 220 coincide. The display module 300 is disposed on the base 100 and is located inside the knob assembly 200. The knob assembly 200 coaxially arranges the first knob 210 and the second knob 220 into a double-layer knob structure, and the two knobs rotate independently. At the same time, the display module 300 is arranged on the knob assembly 200, which can gather three independent components in one place, so that the three mounting holes that originally need to be opened on the water heater are reduced to one mounting hole, reducing the processing steps of opening the holes, and at the same time, making the appearance of the water heater more concise.

[0030] Specifically, the base 100 is used to connect to the corresponding gas water heater, and the first knob 210 and the second knob 220 can independently control two operating parameters of the gas water heater. For example, the first knob 210 can control the water volume, and the second knob 220 can control the gas volume. The first knob 210 and the second knob 220 are coaxially arranged so that the two knobs can form a double-layer structure, which can reduce one installation hole, and the display module 300 can be set as a display screen, which can display the operating parameters of the gas water heater, such as water temperature and other parameters. The display module 300 can be located on the first knob 210 or the second knob 220 so that the user can observe it. Since the knob assembly 200 and the display module 300 are both arranged on the base 100, the gas water heater only needs to open one installation hole to install the above-mentioned knob assembly 200 and display module 300, which can reduce the holes opened in the gas water heater, reduce the processing steps, and improve the simplicity of the appearance of the gas water heater.

[0031] It can be understood that the first knob 210 can be rotatably set on the base 100, and the second knob 220 can be rotatably set on the first knob 210, or the second knob 220 can be rotatably set on the base 100, and the first knob 210 can be rotatably set on the second knob 220, or both the first knob 210 and the second knob 220 can be rotatably set on the base 100, so that the first knob 210 and the second knob 220 can rotate independently relative to the base 100.
