Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown in the figure, the anti-peeping detector provided by this utility model includes a housing 1, an installation plate 10 inside the housing 1, a thermal imager 2 on one side of the outer wall of the installation plate 10, an observation tube 9 penetrating through the installation plate 10, a long-pass filter 3 inside the observation tube 9, the observation tube 9 being aligned with the thermal imager 2, a plurality of infrared lamps 4 being arranged around the observation tube 9, the infrared lamps 4 being located on one side wall of the housing 1, a Type-C port 5 being provided on the installation plate 10, the Type-C port 5 penetrating from the inner cavity to the outer side of the housing 1, an electromagnetic detection element 16 being provided on the installation plate 10, a battery 14 being provided on one side of the installation plate 10, and a buzzer alarm 11, a plurality of signal warning lights 12, a blue warning light 13 and a switch 15 being respectively provided on one side of the installation plate 10.

[0025] In this embodiment, the outer shell 1 is integrally injection molded from ABS engineering plastic, which has good impact resistance and corrosion resistance. An installation plate 10 is provided inside the outer shell 1. The installation plate is a circuit board. A thermal imager 2 is provided on one outer wall of the installation plate 10. The thermal imager 2 uses a high-sensitivity infrared detector. An observation tube 9 is provided through the installation plate 10 to observe obvious reflections generated by the camera lens. A long-pass filter 3 is provided inside the observation tube 9. The long-pass filter 3 is made of multi-layer coated optical glass, which can efficiently filter visible light and stray light with wavelengths less than 800nm, and only allow long-wave infrared light of 800-1100nm to pass through. The observation tube 9 is aligned with the thermal imager 2. Several infrared lamps 4 are provided around the observation tube 9. The infrared lamps 4 use low-power LED chips and are located on one side wall of the outer shell 1.

[0026] Specifically, the mounting plate 10 is equipped with a Type-C port 5, which extends from the inner cavity to the outer side of the outer shell 1. The mounting plate 10 is equipped with an electromagnetic detection element 16. A battery 14 is installed on one side of the mounting plate 10. The battery 14 is a lithium polymer battery. A buzzer alarm 11, several signal warning lights 12, a blue warning light 13, and a switch 15 are installed on one side of the mounting plate 10. The electromagnetic detection element 16 adopts a wideband receiving module that can cover the electromagnetic signal frequency band of 10MHz-6GHz. It has extremely high sensitivity to the transmission signals of common eavesdropping devices and pinhole cameras. When an abnormal signal with an intensity exceeding -70dBm is detected, the buzzer alarm 11 will be triggered immediately.

[0027] In this embodiment, a base plate 17 is fixed to one side of the outer shell 1 with screws. Several light-transmitting sheet groups 8 are provided on the outer wall of the base plate 17. The light-transmitting sheet groups 8 are made of high light-transmitting PC material, which can clearly transmit light signals to the outside of the device and realize intuitive prompts to the user. An observation hole 91 is provided on the base plate 17, and a sound outlet hole 7 is provided on one side of the light-transmitting sheet group 8.

[0028] In this embodiment, the buzzer alarm 11 is located directly below the sound outlet 7, which can reduce the loss during sound propagation and ensure the penetration of the alarm sound. The light-transmitting sheet group 8 consists of several signal light-transmitting sheets and blue light-transmitting sheets. The signal light-transmitting sheets and blue light-transmitting sheets correspond to the signal warning light 12 and the blue warning light 13, respectively. Both the signal warning light 12 and the blue warning light 13 use high-brightness LEDs. The signal warning light 12 is red and lights up when an electromagnetic abnormal signal is detected. The signal warning light 12 will light up a different number of red lights according to the strength of the signal. The blue warning light 13 flashes when the thermal imager detects an abnormal temperature.

[0029] In this embodiment, the observation tube 9 penetrates the outer shell 1, and an observation hole 91 is provided on the bottom plate 17. The observation hole 91 is concentric with the observation tube 9. The long-pass filter 3 is set inside the observation tube 9. When the infrared light emitted by the infrared lamp 4 shines on the camera lens, it will produce obvious reflection points. After the reflection points pass through the long-pass filter 3, they form a clear image at the observation tube 9, which makes it convenient for users to quickly locate the camera position.

[0030] In this embodiment, a switch 15 is provided on the bottom surface of the mounting plate 10, and the switch 15 extends from the inner cavity of the housing 1 to the bottom outer wall of the housing 1. The surface of the switch 15 is provided with anti-slip ridges, and the anti-slip ridges of the bottom switch 15 are evenly distributed laterally, so that the opening or closing operation can be easily completed even when the hands are wet.

[0031] In this embodiment, the outer wall of the outer shell 1 is provided with anti-slip texture 6, and the anti-slip texture 6 is evenly distributed in strip shape. The depth of the strip anti-slip texture 6 is 0.5mm, and the spacing between adjacent textures is 2mm, which can enhance the friction when holding the hand.

[0032] In this embodiment, there are 4-6 infrared lamps 4, and the infrared lamps 4 are arranged in a ring array with the long-wave pass filter 3 as the center.

[0033] The anti-peeping detector provided by this utility model, in practical application, is connected to a mobile phone via the Type-C port 5, and then the device is turned on via the switch 15. Holding the mobile phone, the user observes the data transmitted by the thermal imager 2. When an abnormal temperature is detected, the blue warning light 13 will flash. When the user walks to the abnormal area, the side equipped with the long-pass filter 3 and infrared light 4 is aligned with the area to be detected. The infrared light 4 is turned on, and the user observes through the observation hole 91. With the help of the long-pass filter 3 filtering out interference light, combined with the infrared light emitted by the infrared light 4, the reflection of the camera lens can be clearly detected. During electromagnetic signal detection, the user slowly moves the device so that the electromagnetic detection element 16 on the other side of the casing 1 can detect the surrounding environment to detect whether there are any abnormal electromagnetic signals. If the device detects an abnormal electromagnetic signal, the buzzer alarm 11 will sound an alarm through the sound outlet 7, and the corresponding signal warning light 12 will light up. Then, based on the number of lights on the light-transmitting sheet group 8, the location of the abnormality can be determined for further investigation.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
