Further, an electric heating switch button is also provided on the casing;

The electrothermal switch button is electrically connected to the processor.

Further, the casing is also provided with an antenna, an FM knob, a speaker, a pickup, a power interface and a PTT button;

The casing is also provided with a radio frequency module, a power amplifier module and a sound card module;

By adopting the aforementioned technical solutions, the beneficial effects of the present invention are: the multi-function walkie-talkie is used to check the ambient temperature by setting a temperature sensor on the casing, and each touch element detects whether the human hand is in contact with the multi-function walkie-talkie.

When the ambient temperature difference is lower than the preset value (such as 0°C), and the human hand holds the multi-function walkie-talkie, the processor controls the self-limiting temperature electric heating film corresponding to the touch element in contact with the human hand to heat up. The characteristics can effectively prevent overheating. The utility model controls the heating of the self-limiting temperature electric heating film by detecting when the human hand holds the casing, so that the human hand does not feel cold when holding the casing (when the human hand just holds the casing, because the self-limiting temperature electric heating film is just heated, the The case will still feel cold for a short period of time) to improve the user experience.

Detailed ways

The present utility model will now be further described with reference to the accompanying drawings and specific embodiments.

1 , 2 , 3 and 4 , the present embodiment provides a multifunctional walkie-talkie, including a casing 1 , and the casing 1 is provided with a PTT button 10 , a power interface 12 , an antenna 13 , and a frequency modulation knob 14 , speaker 15, pickup 16 and display screen 17; the casing 1 is also provided with a processor 18, a battery 19, a power amplifier module 20, a sound card module 21 and a radio frequency module 22 (not shown in the figure).

The above electronic components are all existing equipment in the art.

The power interface 12 is electrically connected to the power supply terminal of the processor 18 , and the PTT button 10 , the FM knob 14 , the display screen 17 , the power amplifier module 20 , the sound card module 21 and the radio frequency module 22 are respectively electrically connected to the processor 18 ;

The antenna 13 is electrically connected to the radio frequency module 22;

The speaker 15 is electrically connected to the power amplifier module 20;

The pickup 16 is electrically connected to the sound card module 21 .

Through the above-mentioned circuit connection, the multifunctional walkie-talkie realizes the basic communication function of the walkie-talkie.

The improvement point of the present utility model is:

The casing 1 is also provided with a temperature sensor 2 for detecting the ambient temperature.

A plurality of self-temperature-limiting electric heating films are arranged on the outer surface of the casing 1 at intervals, and the self-temperature-limiting electric heating films are not in contact with each other. A touch element is correspondingly arranged on each piece of the self-limiting electric heating film.

In this specific embodiment, the number of self-limiting electric heating films arranged on the casing 1 is three, and the three self-temperature-limiting electric heating films are arranged on the back of the casing 1 . For the convenience of understanding, each piece of self-temperature-limiting electric heating film is respectively marked as: self-temperature-limiting electric heating film 3 , self-temperature-limiting electric heating film 4 , and self-temperature-limiting electric heating film 5 . A touch element 6 is correspondingly arranged on the self-limiting electric heating film 3 ; a touch element 7 is correspondingly arranged on the self-limiting electric heating film 4 ; a touch element 8 is correspondingly arranged on the self-limiting electric heating film 5 .

The outer surface of the casing 1 is also provided with a protective cover 9 for covering the self-temperature-limiting electric heating film 3 , the self-temperature-limiting electric heating film 4 , and the self-temperature-limiting electric heating film 5 .

The casing 1 is also provided with an electrothermal switch button 11 .

The temperature sensor 2, the self-limiting electric heating film 3, the self-limiting electric heating film 4, the self-limiting electric heating film 5, the touch element 6, the touch element 7, the touch element 8, and the electric heating switch button 11 are respectively connected with the The processor 18 is electrically connected.

The self-limiting temperature electric heating film 3, the self-limiting temperature electric heating film 4 and the self-limiting temperature electric heating film 5 are all existing equipment, such as the one disclosed by Hubei Zhongnuan Graphene Technology Co., Ltd. A kind of PTC self-limiting temperature electric heating film.

The touch element 6 , the touch element 7 and the touch element 8 all use a capacitive touch panel. When the human body touches the capacitive touch panel, the capacitance value of the capacitive touch panel is changed (generally at pf level).
