That is, the electronic switch 43 can switch the voltage through the voltage conversion module 41 to activate the heating module 11 of the heating device, so that the user can heat the heating device 100.

The human body sensing module 80 includes an infrared ray sensor or a microwave sensor.

The human body sensing module 80 faces a set direction for sensing a human body in a specific area; due to the specific orientation of the human body induction module 80, only when a human body enters the specific induction area h, the human body induction module 80 can induce the human body to start the heating module 11.

Specifically, human response module 80 is infrared ray sensor, and infrared ray sensor can judge human entering induction area h through the induction heating, and specifically, this infrared ray sensor includes temperature sensing ware and fixing base, and the temperature sensing ware passes through screw assembly to be installed on the fixing base, then installs the fixing base in power adapter 40 again.

Of course, the human body sensing module 80 may also be a microwave sensor, which determines that the human body enters the sensing area h by sensing the reflection of the electromagnetic wave. Similarly, during actual installation, the microwave sensor is installed on a fixed seat, and then the fixed seat is installed in the power adapter 40.

In actual use, a designer can combine the microblog sensor and the infrared sensor to make the induction of human body when entering more sensitive.

Preferably, as shown in fig. 7, a temperature sensor 70 is disposed on the heat generating module 11 of the heat generating device 100, and the temperature sensor 70 is connected to the MCU 42. When the temperature sensor 70 senses that the heat of the heat generating module 11 reaches a preset value, the MCU42 can control the electronic switch 43 to close, so that the heat generating module 11 stops heating. The heating temperature range usually set is as follows: 1-60 ℃. The power adapter 40 is provided with a button for adjusting the temperature, and the user can set the desired temperature as desired.

Preferably, in practical design application, the power adapter 40 is provided with a display screen 44 for displaying temperature, and the MCU42 is connected to the display screen circuit D. In actual operation, after the temperature sensor 70 transmits the collected temperature to the MCU42, the MCU42 enables the display 44 to display the current heating temperature of the heat generating device 100.

The second power supply line S2 with the plug 60 is coupled to the input interface a, and the first power supply line S1 is coupled to the output interface b.

More preferably, as shown in fig. 2, a plug-in type electrical connection assembly 50 is disposed between one end c of the first power line S1 and the plate-type heat-generating component 10, so that the plate-type heat-generating component 10 and the power adapter 40 can be independent from each other, and daily maintenance or storage and carrying are facilitated; when the power adapter 40 is damaged alone, it is also convenient for the user to replace the power adapter.

The power adapter 40 includes a case 41, a first power line S1 and a second power line S2 are arranged side by side at one side of the case 41, and the sensing head p of the human body sensing module 80 is arranged at the opposite side of the first power line S1 and the second power line S2 of the case 41.

Note that the arrangement of the sensor head p on the opposite side of the housing 41 means: the induction head p is just about the region that the human body need sit in, and this induction head p's radiation zone can design according to actual demand, and after the human body entered into induction zone h, induction head p can sensitively detect. The reason why the sensor head p is just in the region of the sitting and office position of the human body is to prevent the sensor head p from sensing by mistake, i.e. to prevent the sensor head p from being in a sensing state when the human body is not in the office position but moves around the power adapter 40.

The sensing head p of the human body sensing module 80 faces a set direction for sensing a human body in a specific region, and after the human body enters the sensing region, the human body sensing module 80 can sense the human body entering through the detection hole p.

In practical applications, the electronic switch 43 may be selected as a thyristor or a relay by those skilled in the art. And selecting a proper electronic switch type according to the practical application environment.

as shown in fig. 6, the heat generating component 10A of the hard frame type includes a frame a1, a tempered glass a2 as the heat conducting member 12, and a heat generating module A3, and the tempered glass a2 and the heat generating module A3 are located in the frame a 1.

Preferably, the bottom plate of the hard frame type heat generating component 10A is a hard heat insulating wood board 101, a soft heat insulating layer 102 is padded on the hard heat insulating wood board 101, and the heat generating module a3 may be a thin carbon crystal heat generating film, and a heat reflecting layer 103 is padded on the lower layer of the carbon crystal heat generating film.

Preferably, the thin carbon crystal heating film is attached to the lower surface of the tempered glass a2, a gap does not exist between the carbon crystal heating film and the tempered glass a2, and heat generated by the carbon crystal heating film is directly blocked downwards by the heat reflection layer 103, so that more heat generated by the carbon crystal heating film is transmitted to the tempered glass a2 in a more concentrated manner, and the heat utilization rate of the heating module 11 is higher.

In addition, since there is no air under the tempered glass a2, when the carbon crystal heating film is heated, condensation water drops are not generated inside the tempered glass a 2.

More preferably, the heat reflecting layer 103 is a tin foil paper having adhesiveness. Traditional foam thermal-protective coating is heated ageing easily or produces the peculiar smell, and the tin foil paper has better heat resistance, and the tin foil paper also has the effect of heat of reflection in addition, can prevent the heat downward transmission of heating film, makes more heats of heating film upwards transmit in toughened glass.

For the hard heat insulation wood board 101, the heat insulation layer of the wood structure not only can further prevent the heat of the heating film from being transferred downwards, but also can play a role in strengthening the structure.

In practical arrangements, a soft insulating layer 102 may also be provided between the heat reflecting layer 103 and the hard insulating wood board 101. The soft heat insulating layer 102 is a non-woven fabric or oxford fabric with adhesive. The soft heat insulation layer 102 not only prevents the heat of the heating film from being transferred downwards to cause heat waste, but also plays a role in buffering between the toughened glass A2 and the heat insulation wood board 101 to prevent the heat insulation wood board from directly touching the toughened glass A2.

More preferably, waterproof sealing assembly is adopted between the toughened glass A2 and the frame A1, so that heat dissipation can be prevented, and a waterproof effect can be better achieved.
