[0020] Referring to Figures 1-4, the technical solution adopted in this specific embodiment is as follows: It includes a doorbell mounting base 1 and a rotating rain guard 2. The rotating rain guard 2 is movably connected to the doorbell mounting base 1 through a rotating shaft buckle 10. A solar panel 3 is inclinedly arranged on the upper part of the doorbell mounting base 1. A water droplet sensing mechanism 4 and a light sensing mechanism 5 are arranged on the top of the doorbell mounting base 1. A control board 6 is also arranged on the upper part of the doorbell mounting base 1 and electrically connected to the solar panel 3, the water droplet sensing mechanism 4, and the light sensing mechanism 5. In this embodiment, in order to improve the waterproof effect, a rotating rain guard is arranged on the doorbell mounting base, and a rotating handle 21 is arranged above the front end of the rotating rain guard 2. The opening and closing degree of the rotating rain guard can be adjusted by pulling the rotating handle, thereby obtaining different waterproof effects, making it more user-friendly.
[0021] To enhance the functionality of the waterproof cover, this embodiment also includes a water droplet sensor and a light sensor. The water droplet sensor 4 uses an MLX75305 raindrop sensor and is located on the top of the doorbell mounting base 1. The light sensor 5 uses a light sensor, with the sensor probe exposed on the side of the water droplet sensor on the top of the doorbell mounting base 1. The water droplet sensor can detect rain conditions and provide feedback when continuous water droplets are detected, serving as an alarm. At this time, the user can adjust the rotating rain guard according to the rainfall to effectively prevent water damage and also to know the external rain conditions. The light sensor works in conjunction with the doorbell, detecting ambient light and feeding it back to the doorbell control system. The doorbell control system automatically adjusts the screen brightness based on the feedback data to achieve the best visual effect. The inclusion of these two sensing mechanisms greatly enhances the functionality of the waterproof cover and doorbell, providing users with a better user experience.
[0022] In addition, in this embodiment, the waterproof cover can also serve as a charging mechanism to power the doorbell. A solar panel is installed on the doorbell mounting base to receive light energy and convert it into power. When the power supply system fails to power the doorbell, the waterproof cover can serve as a backup power source to power the doorbell, ensuring the continuous use of the doorbell.
[0023] More specifically, the control motherboard 6 is equipped with a main control chip 7 and a Hall sensor 8. In this embodiment, the main control chip 7 is an ESP32-C6 chip, which integrates Wi-Fi 6 / BLE 5.3. It can not only realize integrated control, but also transmit data, especially for transmitting the detection data of the water droplet sensing mechanism. In addition, this embodiment also sets a Hall sensor as an anti-theft element. When installing the device, an electromagnetic element needs to be installed in the mounting position of the doorbell mounting base, corresponding to the position of the Hall sensor. The Hall sensor senses and detects the electromagnetic element. When theft occurs, the magnetic field between the Hall sensor and the electromagnetic element changes, and the Hall sensor sends an alarm signal to the client for notification. At the same time, it triggers the buzzer to emit an alarm sound, thus playing an anti-theft role. It can be understood that the buzzer is installed on the control motherboard (not shown).
[0024] More specifically, the upper back of the doorbell mounting base 1 is provided with a control compartment, which is used to install the control board 6. The control compartment is equipped with a lithium battery 9, and the control compartment is sealed with a control compartment cover 11. In this embodiment, the lithium battery is used in conjunction with the solar panel. It is charged in normal weather and used as a power source in special circumstances.
[0025] More specifically, the doorbell mounting base 1 is also provided with a doorbell mounting back plate 12 on the back. The doorbell mounting back plate 12 has a mounting hole 121 in the middle and a USB plug fixing hole 122 on one side of the bottom. The main power supply line of the doorbell passes through the mounting hole for connection, while the data connection line fixes the plug to the USB plug fixing hole and connects to the connection line led out from the control motherboard.
[0026] More specifically, the top of the doorbell mounting base 1 protrudes upward to form a fixing part 101, and a fixing hole 102 is provided on the fixing part 101. A fixing hole 102 is also provided on the lower side of the doorbell mounting base 1 adjacent to the doorbell mounting back plate 12. The setting of multiple fixing holes can facilitate the installation and fixing of the doorbell mounting base.
[0027] More specifically, a rotating handle 21 is provided above the front end of the rotating rain guard 2, which makes it more convenient to adjust the rotating rain guard.
[0028] More specifically, the doorbell mounting base 1 is made of transparent material. The use of transparent material allows for a wider viewing angle and better performance.
[0029] The working principle of this utility model is as follows: During installation, the doorbell is first installed on the doorbell mounting backplate 12 of the doorbell mounting base 1. The doorbell's power cord passes through the mounting hole 121 and connects to the power supply. At the same time, the doorbell's backup power interface connects to the data cable and fixes the connector to the USB mounting hole, connecting to the data cable led out from the control motherboard 6. The doorbell is charged by the lithium battery 9 through the solar panel 3, thus enabling solar power supply when the main power supply is unavailable, ensuring continuous use of the doorbell. In dry weather, the opening and closing degree of the rotating rain guard 2 can be adjusted by pulling the rotating handle 21 to obtain the best visibility range. In rainy weather, the water droplet sensing mechanism 5 detects the rainfall and feeds back to the user end through the main control chip 7. The system allows for adjustment of the rotating rain guard 2 based on rainfall to ensure optimal waterproofing. The Hall sensor 8 detects the electromagnetic components pre-set at the doorbell mounting base 1. In the event of theft, the magnetic field between the electromagnetic components and the Hall sensor 8 changes, triggering an alarm signal. This controls the buzzer on the main board 6 to emit an alarm sound. The Hall sensor 8 also sends a signal to the client via the main control chip 7, thus providing anti-theft protection. Furthermore, when the doorbell is connected to the main board 6 via a data cable, the light sensor 5 detects light and feeds back the ambient brightness to the doorbell's control system. This allows for automatic adjustment of the doorbell screen brightness based on the ambient light, achieving the best visual effect.
[0030] 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.
