Description

Capacitive sensing electronic float

Technical Field

The utility model relates to a float, concretely relates to electric capacity response electron float.

The float (also called as float) is the eyes of the fisherman, is an essential article in fishing activities, and the fisherman can judge whether the bait exists or not and indicate whether the fish bites the hook or not through the float.

The person of fishing can judge whether to go up the fish through the action of eyes observation float when fishing in daytime, but fishing in the weather darkness or evening, then see unclear or even can't see the float completely. Therefore, the electronic luminous float is born, can well solve the problem of night fishing, and is more favorable for the observation of a fisherman even in the daytime.

A pure electronic luminous float belongs to the 1 st generation electronic float, and the float tail is illuminated by a light-emitting diode so as to be visible in a dark place. However, the light of the fishing float is single, visual fatigue can be generated after the fishing float is facing to the unchanged fishing float for a long time, sometimes fishes drag the fishing float, a fisher cannot quickly respond, the success rate of fishing is influenced, and the fishing pleasure is reduced.

Therefore, the 2 nd generation of the intelligent color-changing electronic float for fish biting is born, the float mainly adopts a micro gravity sensor to capture the sinking and floating actions of the fish when biting, and then utilizes the color change of the LED lamp to transmit the information of the fish biting. Although the scheme solves the problem that the previous generation electronic float is easy to fatigue in vision, the adopted gravity sensor is high in cost, few in sensor manufacturer, easy to lack of goods due to narrow supply chain, easy to be triggered by water surface disturbance in error, low in trigger sensitivity and the like. In order to solve the deficiency of the gravity sensing scheme, manufacturers also develop another type of intelligent color-changing electronic float for fish sensing by using the conductive characteristic of water, and after a fish bites the hook, the float body sinks into water to be conductive to trigger the LED lamp to change color, so that the intelligent reminding function of the fish is realized. However, in the technology, two conducting wires need to extend from the circuit board to be connected with the electrode contact outside the float body, so that time and labor are wasted in production and assembly, the waterproof problem of the electrode contact is solved, and the electrode contact is oxidized to cause functional failure after long-term use.
