Technical Field

[0001] The present utility model application relates to the technical field of control devices, and specifically relates to a touch liquid state control device for liquid in a hollow container. Background Art

[0002] For the convenience of life and the need for control technology in practical applications, it is necessary to implement touch control technical solutions for some liquid media or liquid media in containers. The skin of the human body tissue is a lossy electrolyte, equivalent to a conductive electrode. There is a dielectric layer between two simple parallel plate capacitors. Most of the energy in this system accumulates between the capacitor plates, and a small amount of energy will overflow to the area outside the capacitor plates. When a finger is placed on the capacitive touch system, it is equivalent to being placed in the energy overflow area (referred to as: fringe field), and it will increase the conductive surface area of this capacitive system.

[0003] Currently, the existing solutions use spraying conductive materials on the container wall or triggering by human static electricity. However, such solutions have low sensitivity and are somewhat related to the static electricity carried by the human body, which will affect the sensitivity. Or spraying conductive materials on the container wall, but this process is complex and expensive, and it is more difficult to implement for some insulating and transparent materials. Summary of the Invention

[0004] In order to solve the problem of low sensitivity of the existing control device, the present utility model provides a touch liquid state control device for liquid in a hollow container to solve the above problems.

A conductor penetrates through the surface of the container lid, and a circuit board is fixedly connected to the side of the conductor.

[0007] Preferably, a conductor sealing ring is sleeved on the outer surface of the conductor on the surface of the container lid, and the outer surface of the conductor sealing ring is in contact with the inner wall of the container lid.

[0008] Preferably, container sealing rings are fixedly connected to both sides of the inner cavity of the container lid and at the bottom of the container body, and the top of the container sealing ring is in contact with the container body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, by introducing the capacitance magnetic field frequency signal into the liquid in a liquid state, when a person approaches or touches, the capacitance value changes.
