[0021] As Figure 1-2 shown, a portable on-site physical evidence rapid exploration device includes a rapid exploration device body. The rapid exploration device body includes an industrial camera. The industrial camera includes a housing 1. A cover 2 is detachably connected to the front side of the housing 1. A reagent kit 10 for storing AIE reagents is provided inside the cover 2. A filter 7 is provided on the front side inside the housing 1. A camera 8 is provided behind the filter 7. A laser light source 11 for exciting the AIE reagent is provided on one side of the camera 8. A light-transmitting hole 6 adapted to the laser light source 11 is formed on the front side wall of the housing 1. A battery 12 and a main board 13 are provided inside the housing 1. The laser light source 11 and the battery 12 are both electrically connected to the main board 13. This design has a simple structure and is convenient to use. The integrated design reduces the weight and volume of the device, improves the simplicity and flexibility of operation, and has functions such as video recording and AIE visualization, ensuring the exploration efficiency and accuracy during the exploration process.

[0022] To facilitate the assembly of the housing 1, the housing 1 includes a main housing 3, a rear housing 14, an upper cover 4, and a lower cover 5. The main housing 3 is provided on the front side of the rear housing 14. The upper part of the main housing 3 is connected to the upper part of the rear housing 14 through the upper cover 4. The lower part of the main housing 3 is connected to the lower part of the rear housing 14 through the lower cover 5. The light-transmitting hole 6 is provided on the main housing 3.

[0023] The cover 2 is connected to the main housing 3 by a buckle connection to facilitate the detachable connection between the cover 2 and the housing 1. The cover 2 is provided on the front side of the light-transmitting hole 6. It can block dust and the like from entering the housing 1 by means of the cover 2, thereby playing a protective role for the rapid exploration device body. Moreover, a video recording hole adapted to the camera 8 is also formed on the front side wall of the housing 1, and the video recording hole is located behind the cover 2.

[0024] An embedding groove for clamping the reagent kit 10 is provided inside the cover 2. Striped grooves are provided on the inner wall at the opening of the embedding groove to facilitate the user to take out or replace the reagent kit 10 through the striped grooves.

[0025] An installation hole is provided on the upper cover 4. A power switch 15 for controlling the on / off of the laser light source 11 is provided in the installation hole. The power switch 15 is electrically connected to the main board 13, so that the user can control the on / off of the laser light source 11 through the power switch 15 to excite the sprayed AIE reagent.

[0026] Inside the housing 1, there is a wireless signal transmission module 9, which is electrically connected to the main board 13 to facilitate the timely transmission of the captured images to the remote end for storage, ensuring the efficiency of the investigation process. To ensure the transmission effect of the captured images, the wireless signal transmission module 9 can be one of a Bluetooth module, a Wifi module, a 4G module, or a 5G module.

[0027] The laser light source 11 can adopt a multi-band laser excitation light source to facilitate the accurate detection of different types of physical evidence.

[0028] When in use, the user can remove the cover 2 from the housing 1, take out the reagent kit 10, and use the atomizing device to spray the AIE reagent in the reagent kit 10 onto the surface of the biological sample carrier. Then, press the power switch 15 to control the laser light source 11 to turn on. Using the AIE aggregation-induced emission technology, the AIE reagent is excited by the laser light source 11 to visually display the precise location of the biological physical evidence. The AIE reagent undergoes electrostatic interaction with biological macromolecules (such as amino acids) to form aggregates, thereby generating fluorescence under laser irradiation. The quick investigation device body can also record images through the camera 8 and achieve remote transmission of the recorded images through the wireless signal transmission module 9, ensuring the efficiency, accuracy, and intelligence of the investigation process.

[0029] The utility model has the following beneficial effects:

[0030] (1) The detection efficiency is significantly improved. Through the coordinated operation of the reagent kit and the laser light source, rapid detection is achieved. The biological sample can display clear fluorescence signals in a short time, greatly shortening the overall operation time and facilitating the improvement of the subsequent physical evidence extraction efficiency.

[0031] (2) Functional integration and diversification. The quick investigation device has functions such as recording, AIE detection, and wireless transmission, realizing multiple functions in one device, meeting the detection and evidence collection requirements for various physical evidence at the crime scene, and improving the practicality and application scope of the device.

[0032] (3) Enhanced safety and environmental protection. The AIE detection reagent is used, which is safe and environmentally friendly, harmless to the environment and operators, and ensures the safety of the operation.

[0033] (4) Reduced operator burden. Due to the light weight and simple operation of the device, the operator's burden can be effectively reduced. The crime scene investigators do not need to carry multiple devices, nor do they need to perform complex device switching and operation steps, improving work efficiency and comfort.

[0034] (5) The efficiency and accuracy of on-site investigation are improved. Through integrated design and efficient operation processes, the on-site investigation work becomes more efficient and precise. By quickly revealing evidence, it is conducive to the extraction of physical evidence, ensuring the integrity and accuracy of physical evidence, reducing the possibility of sample contamination and operation errors, and enhancing the overall effect of on-site investigation.
