Vehicle-mounted wireless heating device

Abstract

The invention discloses a vehicle-mounted wireless heating device which comprises a vehicle-mounted wireless charging cup seat and a vehicle-mounted wireless charging cup. The vehicle-mounted wireless charging cup seat comprises a base, a primary side induction coil, a single chip computer controlled circuit, a temperature sensor, a pressure sensor, an indicating light and a fixed support. The vehicle-mounted charging cup comprises a cup with a sleeve, a cup cover with radiating holes, a sub side induction coil and a heater. The vehicle-mounted cup seat is powered by a storage battery, the cup is placed on the cup seat through the fixed support, energy is transmitted to a sub side receiving coil in an inductive coupling mode, the sub side receiving coil transmits the energy to the heater to heat, and the circuit is cut off automatically when the water is heated to a preset temperature threshold. Due to the fact that the water in the cup is heated in an inductive coupling mode, the efficiency of energy transmission is high. Due to the fact that the cup is not connected with the power supply directly, the risk of short circuit is avoided and the heating device is safe to use. Due to the fact that the fixed support and the cup cover are disposed on the heating device, water does not overflow when the vehicle runs, and the heating device is convenient to use.

Description

technical field [0001] The invention relates to the field of inductively coupled non-contact power transmission, in particular to a vehicle-mounted wireless heating device. Background technique [0002] Looking at the current car heating cups, there are mainly the following implementation methods: 1. The heater is directly driven by 24V voltage, but the water in the heater will overflow when the car is bumpy or in other bad situations, causing a short circuit, which is safe. Hidden dangers; 2. The heater is fixed through the protection box, but the protection box is generally relatively large, occupying the cab space, which is not easy to promote; 3. The electromagnetic induction heating method, but the electromagnetic induction method relies on the eddy current effect to heat, and there is magnetic radiation And other safety hazards, at the same time, only eddy current can be generated at the bottom of the cup, and the heating efficiency is relatively low.
