Abstract

The invention discloses a charging circuit, a charging device and a capsule endoscope charging system, and the charging circuit comprises an electric energy input end, a sampling control circuit, a comparison circuit, a pulse generation circuit and a power supply circuit. The electric energy input end is sequentially connected with the sampling control circuit and the power supply circuit; the polarity control end of the power supply circuit is connected with the pulse output end of the pulse generation circuit and is configured to switch the charging polarity direction under the action of a pulse signal; the comparison circuit comprises a first comparison branch, and the first comparison branch is connected with the sampling output end of the sampling control circuit through a sampling input end, is connected with the limiting input end of the pulse generation circuit through a first comparison output end, and is configured to control the pulse generation circuit to output a constant electric signal when the sampling electric signal meets a first preset condition. The charging circuit provided by the invention can realize self-adaptive polarity charging, shorten the duration of a reverse connection state, adjust output in time and adapt to various to-be-charged devices.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging circuit, a charging device and a capsule endoscope charging system. Background technique [0002] Batteries are widely used in various electronic devices. They can not only provide electrical energy for electronic devices to realize their functions through discharge, but also receive external electrical energy input to achieve recycling. Currently, devices with storage batteries are usually configured for one-way charging. Users need to strictly distinguish the polarity direction of the device connected to the charging circuit so that it can cooperate with the charging circuit in order to charge normally. [0003] Polarity judgment and switching schemes are provided in the prior art to solve this problem, but on the one hand, the polarity judgment process mostly adopts the scheme that the electronic equipment is configured to discharge to the charging circuit side, an...
