Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, and more specifically, to a wireless charger. Background Art

[0002] A wireless charger is a device that can transfer electrical energy to a device that supports wireless charging by means of wireless power transmission, thereby achieving the function of charging. It achieves wireless charging through the principle of electromagnetic induction. A wireless charger consists of two main components: a transmitter and a receiver. The transmitter is usually a power supply device that converts electrical energy into wireless power and transmits it. The receiver is a receiving device on the device being charged that receives the wireless power and converts it into electrical energy for the device to use.

[0003] Among them, it was found through searching that the patent application number CN202321009108.8 discloses a wireless charger, in which the mobile phone holder of this product includes a rear wall vertical plate shell and at least two plastic plates installed forward; an electrical cavity is opened inside the rear wall vertical plate shell, and a wireless charging controller is fixed in the electrical cavity; all plastic plates are arranged horizontally, and the rear ends of all plastic plates are fixedly connected to the front of the rear wall vertical plate shell, and the plastic plates are arranged in upper and lower layers, and a mobile phone charging space is formed between the plastic plates; a mobile phone wireless charging plate is inlaid in the concave part on the top of each plastic plate, and the wireless charging controller is connected to each mobile phone wireless charging plate through branch wires, and the branch wires are inserted into the vertical plate wire holes and the plastic plate wire holes;

[0004] When this structure is in use, at least two layers of mobile phone wireless charging plates are set up through the charger, and the upper and lower layers can be charged simultaneously; when multiple layers of mobile phone wireless charging plates are set up, multiple mobile phones can be charged at the same time, and there is no need to equip each mobile phone with a charger. However, wireless charging is charged through an electromagnetic field. When in use, this structure is easily affected by external factors and causes disconnection during charging. At the same time, a large amount of heat is generated during charging, which reduces the battery life. Utility Model Content
