[0002] In the cold winter, as temperatures plummet, the need for heating equipment becomes increasingly urgent. Electric heating equipment, due to its convenience and efficiency, has become the choice of many consumers. Currently, the widely used electric heating equipment on the market meets people's heating needs to a certain extent, providing strong support for people to resist the severe cold.

[0003] However, most existing electric heating devices lack intelligent control and require manual operation to turn on and off. If users forget to turn them off, it will not only cause a lot of energy waste, but may also cause serious safety hazards such as fires. On the other hand, some devices use human infrared PIR pyroelectric infrared sensors for control, but these sensors are directional and require a special guide hole structure for installation. They also need to be fitted with lenses and are easily contaminated with dust and debris during use, which reduces their sensitivity. In addition, these sensors cannot penetrate objects and can only be installed in a visible position on the surface of the product. Furthermore, their sensing distance is relatively far, which can easily lead to malfunctions and cause many inconveniences for users. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-5This utility model provides a technical solution: an intelligent electric heating device, including a shell 100, an annular heat cavity 110 inside the shell 100, an annular electric heating device 120 installed inside the heat cavity 110, and an installation cavity 140 enclosed in the middle of the shell 100 by an annular heat insulation plate 130. A control board 200 is installed inside the installation cavity 140, and a Doppler radar 300 installed inside the installation cavity 140 is mounted on the top of the control board 200. The top of the 10 is provided with an annular protective cover 150, which is fixedly connected to the top of the outer shell 100. The back of the outer shell 100 is provided with a fan 400 that blows the heat generated by the electric heating device 120 out of the hot cavity 110 and dissipates heat from the inside of the mounting cavity 140. The back of the fan 400 is provided with a fan protective cover 410 installed on the back of the outer shell 100. The back of the fan protective cover 410 is provided with a plug-in socket 420, which is detachably connected to an oscillation mechanism 500.

[0023] Specifically, when the equipment is working, the Doppler radar 300 uses the Doppler effect to sense the movement of people in the surrounding environment, providing an important basis for the intelligent control of the equipment. This allows the oscillating mechanism 500 to adjust its angle according to the movement of people, so that the blown hot air can track the user and meet the heating needs of users in different positions. When the electric heating device 120 is working, the fan 400 installed on the back of the outer casing 100 starts to run. The fan 400 blows out the heat generated by the electric heating device 120 in the hot cavity 110 to provide warmth to the user. At the same time, the fan 400 also dissipates heat inside the mounting cavity 140, ensuring that electronic components such as the control board 200 work in a suitable temperature environment. The fan guard 410 on the back of the fan 400 ensures the safe operation of the fan 400 and prevents foreign objects from entering.

[0024] In this embodiment, the bottom of the outer casing 100 is provided with a plurality of ventilation slots 160 communicating with the interior of the hot cavity 110. The bottom of the outer casing 100 is also provided with heat dissipation holes 170 communicating with the interior of the mounting cavity 140. A temperature display 180 and a plurality of control buttons 190 are fixedly installed on the outside of the outer casing 100. The temperature sensing probe of the temperature display 180 is placed inside the hot cavity 110.

[0025] Specifically, the heat generated by the electric heating device 120 can be blown out of the hot cavity 110 through the ventilation slot 160 and the fan 400, and the heat generated by the control board 200 and the Doppler radar 300 can be blown out of the mounting cavity 140 through the heat dissipation hole 170 and the fan 400.

[0026] The temperature sensor inside the hot cavity 110 can monitor the temperature inside the hot cavity 110 in real time and feed the temperature information back to the temperature display 180. Users can intuitively understand the heating status of the heating device through the temperature display 180. When users feel that the indoor temperature is too high or too low, they can adjust the heating power of the electric heating device 120 or the speed of the fan 400 through the control button 190.

[0027] In this embodiment, the electric heating device 120 includes an annular shell 121 fixedly installed inside the hot cavity 110. Multiple electric heating elements 122 are fixedly installed inside the annular shell 121, and the multiple electric heating elements 122 are equidistantly distributed inside the annular shell 121.

[0028] Specifically, when the device is powered on and started, the electric heating element 122 begins to work, converting electrical energy into heat energy. Since the electric heating elements 122 are equidistantly distributed, the heat conditions at various locations within the hot cavity 110 are basically the same, avoiding local overheating or overcooling.

[0029] In this embodiment, an annular ambient light 141 is fixedly installed at the opening of the mounting cavity 140.

[0030] Specifically, when the indoor lighting or ambient light is dim, the ring-shaped ambient light 141 will emit a soft light when the heating device is turned on, which can play a certain lighting role, making it easier for users to operate the device in the dark, while also creating a warm and comfortable atmosphere.

[0031] In this embodiment, the swaying mechanism 500 includes a plug-in plate 510 that plugs into the plug-in socket 420. One end of the plug-in plate 510 is connected to an electric servo motor 520. The bottom of the electric servo motor 520 is equipped with a fixing seat 530, which can be a fixing plate, a suction cup, a magnetic plate, or a clamping clip.

[0032] Specifically, the plug plate 510 of the oscillating mechanism 500 is plugged into the plug socket 420 on the back of the fan guard 410, realizing the convenient connection between the oscillating mechanism 500 and the main equipment. When the Doppler radar 300 senses the movement of people and needs to adjust the airflow direction of the heating equipment, the electric servo motor 520 can precisely control the oscillation angle so that the hot air blown out by the equipment can accurately blow on the people who are heating.

[0033] The versatile mounting base 530 can meet the fixing needs of different scenarios. When used on smooth marble floors, a suction cup can be selected as the mounting base 530 to use atmospheric pressure to stably fix the device. When used on metal tables, the magnetic plate can be used to attach the device to the table surface through magnetic force. If used in some temporary settings, the clamp can fix the device in a suitable position. The mounting plate is suitable for placement on relatively flat and stable surfaces. The diverse fixing methods enable the smart electric heating device to work stably in various complex environments, meet the user's needs for adjusting the position and angle of the heating device in different scenarios, and improve the versatility and practicality of the device.

[0034] In this embodiment, the surface of the control board 200 integrates a heating control circuit, a microcontroller, a wireless transceiver module, a relay, and a voice control module. The Doppler radar 300, the temperature sensor, the heating control circuit, the wireless transceiver module, the relay, and the voice control module are all electrically connected to the microcontroller. The microcontroller is electrically connected to the temperature display 180, the electric heating element 122, the ambient light (141), and the electric servo motor 520. The microcontroller is also electrically connected to the power cord through the control button 190.

[0035] Specifically, when a user issues a voice command, such as "turn on the heater," the voice control module receives the sound signal, converts it into an electrical signal, and transmits it to the microcontroller. After analyzing and processing the signal, the microcontroller controls the electric heating element 122 in the electric heating device 120 to start working via a relay. At the same time, the fan 400 is activated to blow out the heat generated in the heating cavity 110. The heating control circuit precisely adjusts the heating power of the electric heating element 122 to ensure a stable temperature rise.

[0036] The Doppler radar 300 monitors the surrounding environment for human activity in real time. When it detects someone approaching, it sends a signal back to the microcontroller via electrical connection. The microcontroller can then adjust the device's operating status according to a preset program. The temperature sensor sends the temperature information inside the hot cavity 110 back to the microcontroller in real time. Based on the set temperature range, the microcontroller adjusts the working status of the electric heating element 122 through the heating control circuit to achieve precise temperature control.

[0037] The wireless transceiver module enables the heating device to have remote control functionality. Users can communicate wirelessly with the device through mobile apps and other terminal devices. Users can turn on the heating device in advance through the mobile app. Of course, users can also control the device manually by operating the control button 190. The multi-module collaborative operation mode enables the smart electric heating device to achieve a high level of intelligence, convenience and reliability, meeting the diverse needs of modern users for smart heating devices.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
