Projection mobile phone and projection device

Abstract

The embodiment of the invention relates to the technical field of mobile phones, in particular to a projection mobile phone and a projection device. A projection mobile phone comprises an exhaust fanused for exhausting air and dissipating heat for the projection mobile phone; the exhaust fan is arranged on the circuit board or the rear cover; ventilation holes are formed in the area, corresponding to fan blades of the fan, of the rear cover and used for ventilation and heat dissipation. The projection device comprises the projection mobile phone and further comprises a charging device and a supporting device 71. The charging device comprises a mobile phone seat frame 721 and a key area 722; and the USB fan socket is arranged in the key area, and the USB fan dissipates heat for the mobilephone, so that the heat dissipation performance of the projection mobile phone is improved.

Description

Problems solved by technology

[0003] The circuits of smart projection mobile phones mainly include: radio frequency circuit, voice circuit, processor and memory circuit, projection drive board circuit; power supply and charging circuit, operation and screen display circuit, interface circuit, and other functional circuits, including Bluetooth, antenna, Radio, sensor, vibrator, projection camera circuit; also includes processor, memory, LED light source, mirror, radio frequency chip, radio frequency power amplifier chip, processor chip, power management chip, memory chip, touch screen control chip, projection chip, etc.; When the projection mobile phone is in the working state of projection, the power of the chips on the circuit board and circuit electronic devices is large, and the heat generation is high. Since the back cover of the existing projection mobile phone is generally a sealed structure, which is not conducive to heat dissipation, the heat generation of the projection mobile phone serious;

The body temperature of the projection mobile phone is very high when it is working, and long-term work will cause damage to the chip on the circuit board, and even affect the normal operation of the original projection mobile phone
