Detailed Implementation

[0036] Example 1

[0037] See Figures 1-14 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a mirror frame 1, with a lens 101 sealed at the front end inside the mirror frame 1. A heating film 8 is provided on the inner surface of the lens 101. When the mirror is used in some humid environments, fog inevitably adheres, affecting the use effect. Especially when used in the bathroom, a large amount of water vapor adheres to the surface of the lens, greatly affecting the user experience. Therefore, a heating film is provided in this embodiment. After detecting water vapor and forming fog, the heating function of the heating film is automatically activated to evaporate the water vapor and regain a clear use effect. A temperature and humidity sensor 5 is provided at the bottom edge of the mirror frame 1, and the detection head of the temperature and humidity sensor 5 is exposed outside the mirror frame 1. The temperature and humidity sensor can detect the external temperature and humidity conditions and display them on the display screen. At the same time, the humidity detection result of the temperature and humidity sensor is also the key to triggering the heating film to heat up. Automatic heating and defogging and stopping defogging are realized by setting the upper and lower limits of the trigger threshold.

[0038] A controller 2 is provided at the lower part of the heating film 8. A display screen 21 is provided on the controller 2. The display screen 21 is provided with a time, calendar display area, weather conditions and temperature and humidity display area. In this embodiment, by setting a display screen on the controller, the time, calendar, weather and temperature and humidity can be displayed, so as to facilitate users to make more appropriate clothing matching according to the environmental conditions.

[0039] A colorful running light 6 is attached around the inner surface of the lens 101 and electrically connected to the controller 2. In this embodiment, in order to obtain dynamic lighting and atmosphere effects, a colorful running light is set as a background ambient light. The colorful running light is a light strip composed of multiple RGB LED beads, which can quickly switch between RGB three colors to display, thereby bringing users different dynamic atmosphere effects as needed.

[0040] The controller 2 is equipped with a radar human body sensing module 9, which is close to the lens 101. In order to realize intelligent light start and stop, the radar human body sensing module 9 has a built-in onboard radar sensing antenna to detect the user's approach and departure. When the user is within the detection range, a light-on signal is triggered, and the controller controls the light to turn on. When the user moves away, the light automatically turns off, which is more intelligent and user-friendly, and brings a better user experience.

[0041] Speakers 7 are symmetrically arranged at the bottom of the inner frame 1. To enrich the functionality of the mirror, speakers are also provided in this embodiment. The speakers can play music or be connected to a mobile phone for calls, allowing users to answer calls directly on the mirror when their hands are wet and it is inconvenient to operate the phone, thus improving the user experience. This is especially useful when the phone is not nearby while showering.

[0042] More specifically, the controller 2 is electrically connected to the temperature and humidity sensor 5, the speaker 7, the heating film 8, and the radar human body sensing module 9. As the control core, the controller is electrically connected to and controls each electrical component.

[0043] More specifically, a microphone 3 is provided on the right side of the frame 1. The microphone 3 is electrically connected to the controller 2. In this embodiment, the microphone is used in conjunction with a speaker to realize the voice call function.

[0044] 11. More specifically, the controller 2 is provided with a touchpad 22 adjacent to the display screen 21. The touchpad 22 includes a volume up button, a volume down button, a function button, a Bluetooth on / off button / call answer / hang-up button, and a light on / off button. In this embodiment, in order to achieve a sensitive touch effect on a 5-6mm wet mirror, a high-sensitivity anti-interference touch control chip 212 is used. The corresponding function button can be touched on the mirror surface to perform the operation without being affected by water droplets, thus improving the user experience.

[0045] More specifically, the controller 2 also includes a control motherboard 23, which houses a power supply circuit 24 and a Bluetooth MCU control circuit 25. The power supply circuit 24 and the Bluetooth MCU control circuit 25 are electrically connected. The control motherboard 23 also includes a temperature and humidity acquisition circuit 26, a color-changing scrolling light drive circuit 29, a display screen drive circuit 211, a touch MCU circuit 212, a microphone circuit 213, a heating and defogging control circuit 214, a power amplifier circuit 216, and a weather-obtaining Wi-Fi circuit 217. Circuit 212, sound pickup circuit 213, power amplifier circuit 216, and weather WIFI acquisition circuit 217 are all electrically connected to Bluetooth MCU control circuit 25. Touch MCU circuit 212 is electrically connected to heating and defogging control circuit 214 and radar human body sensing module 9. Temperature and humidity acquisition circuit 26 is electrically connected to temperature and humidity sensor 5. Colorful running light driving circuit 29 is electrically connected to colorful running light 6. Colorful running light driving circuit is a driving circuit based on AMR-Cortex chip, which controls colorful running light to display different colors alternately, thereby providing a dynamic atmosphere effect and bringing users an atmosphere experience different from static light sources.

[0046] The display driving circuit 211 is electrically connected to the display screen 21, the touch MCU circuit 212 is electrically connected to the touchpad 22, the sound pickup circuit 213 is electrically connected to the microphone 3, the heating and defogging control circuit 214 is electrically connected to the heating film 8, the touch MCU circuit 212 is electrically connected to the radar human body sensing module 9, and the power amplifier circuit 216 is electrically connected to the speaker 7. In this embodiment, the Bluetooth MCU control circuit is the main control circuit, which controls the operation of all circuit components. Each circuit module corresponds to the corresponding electrical component and performs driving control. The driving of the light is controlled by the corresponding driving circuit, while the touch MCU circuit detects and senses the touchpad, obtains the touch event, and performs specific operation settings for each function.

[0047] More specifically, the Bluetooth MCU control circuit 25 uses an integrated chip for circuit control, with a built-in high-speed MCU and classic Bluetooth and BLE 5.0, enabling Bluetooth connection with external electronic devices.

[0048] More specifically, the temperature and humidity sensor 5 is a Sensirion SHT20 digital temperature and humidity sensor. The dehumidification start threshold of the temperature and humidity sensor 5 is 78%RH, and the dehumidification stop threshold is 70%RH. 78%RH is the upper limit threshold for heating and defogging. When the humidity of the mirror reaches the upper limit threshold, the heating signal is triggered to defog. When the humidity drops to the lower limit threshold, the heating stops. The automated control system is more user-friendly and more energy-efficient.

[0049] The radar human body sensing module 9 is a radio frequency human body sensing sensor that transmits and receives 5.8GHz microwaves. It detects human body not only by analyzing the Doppler frequency shift, phase difference and time of flight of the reflected wave, but also by detecting extremely small movements (such as breathing and gestures), making the identification of user behavior more accurate. Moreover, it only requires the removal of the copper or silver layer on the back of the lens by laser milling to provide a radio frequency signal transmission channel for the radar human body sensing module, without the need to make holes in the lens surface.

[0050] To reduce costs, a thermistor can be used instead of the radar human body sensing module. In this embodiment, the thermistor is connected and automatically identified by software.

[0051] More specifically, the heating film 8 has a power density of 25W / dm³. 2 The flexible silicone heating film 8 has openings that match the control box 2. In this embodiment, the flexible silicone heating film is used to facilitate production and processing.

[0052] Example 2

[0053] See Figures 15-16 As shown, the difference between this embodiment and embodiment 1 is that a three-color temperature light strip 10 is pasted around the inner surface of the lens 101, and a three-color light strip driving circuit 28 is provided on the control main board 23. The three-color light strip driving circuit 28 is electrically connected to the three-color temperature light strip 10. In this embodiment, the three-color temperature light strip replaces the color-changing marquee. The three-color temperature light strip can provide three color temperatures for switching and provides light from all around the lens, which is suitable for users who prefer a quieter atmosphere. Other structures and connection methods are the same as in embodiment 1.

[0054] Example 3

[0055] See Figures 17-18 As shown, the difference between this embodiment and embodiment 1 is that a screw-type tri-color bulb 4 is provided in the center of the frame 1, and a tri-color bulb drive circuit 27 is provided on the control main board 23 and electrically connected to the tri-color bulb 4. In this embodiment, a screw-type tri-color bulb is used instead of a color-changing running light to provide light from the center of the lens, which can better highlight the concentrated area of ​​light. The screw-type bulb is also easier to replace, and the user can replace it at any time as needed. At the same time, the cost is lower. Other structures and connection methods are the same as in embodiment 1.

[0056] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting multiple light strips, not only can multi-color lights be switched at will, but also a colorful running light effect can be achieved. It can also display calendar and weather online. With Bluetooth and speaker playback functions, remote control and music playback effects can be achieved, which greatly enriches the functionality of the mirror and brings users a better atmosphere and user experience.

[0057] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
