Problems solved by technology

However, this method will have different effects on the current passing through the electrodes due to the difference in water quality. For example, because pure water has a large resistance, the current passing through the electrodes is small; The electrode current will be relatively large
Therefore, the same amount of water will generate different currents due to different water quality, and the generated currents will even be quite different, so errors in detection and judgment will occur
Moreover, this electrode type water level detection can only be a single-point detection, such as detecting the maximum value, but cannot detect the water level in the kettle in real time.

Embodiment 1

[0038] An embodiment of the capacitive water level detection device of the present invention includes a capacitor structure and a control circuit for detecting the capacitance of the capacitor structure. The capacitor structure includes a container provided with a conductive part and a conductive column arranged in the container. The conductive column The surface is covered with insulating material, the conductive cylinder and the container are insulated from each other, and the conductive cylinder and the conductive part of the container are respectively electrically connected to the control circuit through a coupler.

[0039] The conductive part of the container and the conductive cylinder are insulated from each other because the surface of the conductive cylinder is covered with insulating material, and the two constitute two electrodes of the capacitor. When the water level in the container is gradually increased, the height of the conductive cylinder submerged in water al...

Embodiment 2

[0041] Such as Figure 1 to Figure 3 Shown is the first embodiment of the capacitive water level detection kettle of the present invention. Such as figure 1As shown, the kettle includes a kettle body 20 and a base 10 electrically connected to each other through a coupler 30, a conductive part is provided inside the kettle body 20, and a conductive column covered with an insulating material 41 is provided on the inner bottom surface 21 of the kettle body 20. body 40 , the conductive part and the conductive cylinder 40 covered with insulating material 41 form a capacitor structure together. The base 10 is provided with the control circuit 11 , and the conductive cylinder 40 is electrically connected to the control circuit 11 through the coupler 30 .

[0042] In this embodiment, the pot body 20 is made of a glass pot or the like, which is made of non-conductive material itself, so the inner bottom surface 21 of the pot body 20 is set as a conductive part, and the conductive colu...

Embodiment 3

[0047] Such as Figure 4 to Figure 7 Shown is the second embodiment of the capacitive water level detection kettle of the present invention. The difference from the second embodiment is that the pot body 20 is made of a stainless steel pot or the like and is made of conductive material itself, so the inner wall surface or the inner bottom surface of the pot body 20 can be directly used as the conductive part. It can be understood that, considering the safety of use, even if the kettle body 20 is directly used as a conductive part, a protective structure will be provided in the actual design to avoid danger when the user uses it.

[0048] This embodiment also serves as an improvement to Embodiment 2, such as Figure 4 As shown, in this embodiment, a bare segment conductor 42 is extended upwards at the end of the conductive cylinder 40 away from the inner bottom surface 21 of the kettle body 20. The surface of the exposed segment conductor 42 is not covered with insulating mate...
