Safety protection device for mobile phone charging head, charger, wall socket and power strip

Abstract

The invention discloses a safety protection device for a mobile phone charging head, a charger, a wall socket and a power strip. The device comprises a mains supply connector, an anti-thunder module,an electromagnetic switch, an inductor, a two-jack socket with a temperature probe, a current detection module and a temperature detection module, wherein the mains supply connector is connected to mains supply, the mains supply connector, the anti-thunder module, the electromagnetic switch and the two-jack socket are sequentially electrically connected, the externally connected mobile phone charging head is inserted into the two-jack socket, the mobile phone charging head is connected to a to-be-charged mobile phone and then connected to a mobile phone charging interface circuit and a mobilephone internal battery; a mutual inductor is connected to an electromagnetic switch for power acquisition; an input end of the current detection module is connected to the mutual inductor to acquire current data of the mutual inductor, and an output end is connected to the electromagnetic switch and sends a control signal to the electromagnetic switch according to the magnitude of current of the mutual inductor; an input end of the temperature detection module is connected to the two-jack socket to acquire temperature data at the two-jack socket, and an output end is connected to an electromagnetic switch and sends a control signal to the electromagnetic switch according to temperature.

Description

technical field [0001] The invention relates to the field of mobile phone safety protection, in particular to a mobile phone charging head leakage protection and overheating protection device, a charger, a wall socket and a plug strip. Background technique [0002] In recent years, accidents caused by mobile phone charging have been on the rise year by year, mainly in two aspects: [0003] The first aspect is the personal electric shock casualty accident caused by the leakage of the charging head of the mobile phone. Searching on Baidu with the keyword "mobile phone was electrocuted while charging", there are as many as 2.41 million relevant results. In 2106 alone, there were as many as 8 credible casualty accidents reported by the domestic media, and the cause of the accidents were all playing while charging. Mobile phones, but the number of personal injury accidents that have not been reported should be several times higher. [0004] In the second aspect, fire accidents ...

[0004] In the second aspect, fire accidents caused by mobile phone charging——

In addition, many people also plug in their mobile phones to charge all night. After charging, the mobile phone charging head is still plugged into the mains socket.

After long-term use of the mobile phone charging head, the internal components are aging and invalid, and the faults of leakage and overheating will occur, which will lead to personal electric shock and fire. The time of fire is often when people are sleeping at night, or when there is no When it happens, the loss is huge and it is difficult to prevent
