It is designed to conveniently and efficiently determine whether someone has consumed alcohol and the degree of alcohol intake in various scenarios, such as traffic enforcement, restaurants, and entertainment venues, thereby ensuring traffic safety and regulating order in these locations.

[0003] However, in practical use, the following technical problems have been found in existing portable alcohol content detectors:

[0004] Regarding the nozzle design, some detectors have nozzles that are not securely fixed, causing them to wobble during testing and leading to inaccurate results. Furthermore, disassembly and replacement are inconvenient, failing to meet the requirements for rapid nozzle replacement in high-frequency use scenarios to ensure hygiene and increasing the risk of cross-infection. In terms of protective features, most detectors lack effective protection at the air inlet, allowing dust and liquids to enter, affecting testing accuracy and potentially damaging internal circuits and sensors, resulting in shortened equipment lifespan and increased maintenance costs.

[0005] In response to this technical problem, this application proposes a portable alcohol content detector. Utility Model Content

[0025] 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.

[0026] Reference Figures 1-3This utility model provides an embodiment of a portable alcohol content detector, comprising a housing 1, a slide 2 fixedly connected to the top of the housing 1, an air inlet pipe 7 fixedly connected to the top right end of the housing 1, a limiting groove 9 on both the left and right sides of the top of the air inlet pipe 7, a sleeve 8 fixedly connected to the center of the top of the air inlet pipe 7, a pressure plate 11 detachably connected to the middle of the outer wall of the sleeve 8, a limiting block 10 fixedly connected to the left and right ends of the bottom of the pressure plate 11, the limiting block 10 being detachably connected to the limiting groove 9, a rotating ring 12 threadedly connected to the top of the outer wall of the sleeve 8, a mouthpiece 13 detachably connected inside the air inlet pipe 7, a positioning groove 14 provided at the bottom of the outer wall of the mouthpiece 13, the positioning groove 14 being connected to the limiting block 10 through a positioning component 15.

[0027] Specifically, when the mouthpiece 13 needs to be installed, it is inserted into the air inlet pipe 7. The rotating ring 12 is rotated to move it downward, causing the pressure plate 11 and the limiting block 10 to descend. The limiting block 10 is inserted into the limiting groove 9 for initial positioning. At this time, the positioning block 1502 pops out under the action of the spring piece 1503 and slides into the positioning groove 14, thus achieving stable fixation of the mouthpiece 13. This structure allows the mouthpiece 13 to be disassembled and replaced and is installed firmly, preventing inaccurate test results due to shaking during the testing process. Its additional benefit lies in facilitating the rapid replacement of the mouthpiece 13. In scenarios where the detector is used frequently, such as during traffic police enforcement, the mouthpiece 13 can be quickly replaced to meet the hygiene needs of different testing subjects, greatly improving testing efficiency. Simultaneously, because the mouthpiece 13 is fixed stably, the risk of gas leakage due to insecure installation is reduced, ensuring that exhaled gas can stably reach the testing site through the air inlet pipe 7 during the testing process, further ensuring the reliability of the test results. Moreover, the detachable nozzle 13 is easy to clean and maintain. When the nozzle 13 gets dirty or smelly after a period of use, it can be easily disassembled for cleaning, which extends the service life of the nozzle 13 and the entire testing instrument and reduces the cost of using the equipment.

[0028] Reference Figure 1 , Figure 4 and Figure 5A protective plate 3 is detachably connected to the top of the inner wall of the slide block 2. A slide groove 5 is provided at the top right side of the housing 1. A limit groove 16 is provided at the top left side of the inner wall of the slide groove 5. A slide plate 6 is slidably connected to the inner wall of the slide groove 5. The slide plate 6 is connected to the slide plate 6 through a reset component 17. The positioning component 15 includes a slide groove 1501. The slide groove 1501 is located at the bottom end of the side of the limit block 10. A positioning block 1502 is slidably connected to the inner wall of the slide groove 1501. A spring piece is fixedly connected to each side of the positioning block 1502. 1503, the reset assembly 17 includes a limiting rod 1701 and a slider 1703. The limiting rod 1701 is fixedly connected to the inner wall of the limiting groove 16. A spring 1702 is provided on the outer side of the limiting rod 1701. The slider 1703 is fixedly connected to the rear side of the slide plate 6. The slider 1703 is slidably connected to the outer side of the limiting rod 1701. A storage cavity 4 is provided at the top left end of the slide block 2. The protective plate 3 is L-shaped. The right side of the outer wall of the protective plate 3 is attached to the left side of the slide plate 6. An anti-slip groove 18 is provided on the right side of the slide plate 6.

[0029] Specifically, when the detector is not in use, the sliding plate 6 is pushed to slide along the slide groove 5, and then the protective plate 3 is inserted into the top of the inner wall of the slide block 2 along the installation direction. Under the action of the spring 1702, the sliding plate 6 automatically resets to limit the protective plate 3 and prevent it from falling off. In terms of the protective function of the protective plate 3, it not only blocks dust but also prevents liquid from splashing into the air inlet pipe 7. In some complex operating environments, such as sudden rain during outdoor duty or liquid spillage at the testing site, the protective plate 3 can provide reliable protection for the detector, preventing internal circuit short circuits or sensor damage caused by liquid ingress, thereby extending the lifespan of the detector and reducing equipment maintenance costs.

[0030] In terms of ease of operation, the sliding plate 6 and spring 1702, along with other reset mechanisms, make the installation and removal of the protective plate 3 extremely simple and smooth. Operators can easily install and remove the protective plate 3 by simply pushing the sliding plate 6, without the need for additional tools. Even in emergencies, the detector can be quickly protected or activated, greatly improving work efficiency. From a hygiene perspective, the storage cavity 4 provides a relatively enclosed and clean space for storing the spare nozzle 13. This effectively prevents the spare nozzle 13 from becoming contaminated with dust, bacteria, or other pollutants during storage, ensuring that it is clean and hygienic when it needs to be replaced. This further guarantees hygiene and safety during the testing process and reduces the risk of cross-infection. Furthermore, in terms of portability, the detector maintains its compact and portable design while providing protection and storage functions, making it easy to carry to different testing locations and meet the needs of various scenarios.

[0031] Working principle: When using this portable alcohol content detector, after inserting the mouthpiece 13 into the air inlet pipe 7, rotating the rotating ring 12 causes it to move downwards due to its threaded structure. This, in turn, causes the pressure plate 11 and the limiting block 10 connected to it to descend. The limiting block 10 then inserts into the limiting groove 9 to complete the initial positioning. At the bottom end of the side closest to the limiting block 10, a second sliding groove 1501 is provided. The inner wall of the second sliding groove 1501 is slidably connected to the positioning block 1502, and the opposite side of the positioning block 1502 is fixedly connected to the spring piece 1503. After the limiting block 10 descends to its final position, the positioning block 1502 is ejected by the elastic force of the spring piece 1503 and slides into the positioning groove 14 at the bottom end of the outer wall of the mouthpiece 13, stabilizing the mouthpiece 13 from multiple angles and achieving stable fixation.

[0032] When the detector is not in use, push the slide plate 6 along the slide groove 5. At this time, the spring 1702 is compressed. After the L-shaped protective plate 3 is inserted into the top of the inner wall of the slide block 2 along the installation direction, release the slide plate 6. Under the elastic force of the spring 1702, the slide plate 6 automatically returns to its original position, and its left side fits against the right side of the outer wall of the protective plate 3, limiting the protective plate 3 and preventing it from falling off. The protective plate 3 covers the air inlet pipe 7 to prevent dust and liquid from entering. At the same time, the storage cavity 4 opened at the top left end of the slide block 2 has a regular spatial structure and can be used to store spare nozzles 13. Its relatively closed design can effectively prevent the spare nozzles 13 from being contaminated. When the detector needs to be used, push the slide plate 6 in the opposite direction. The slide plate 6 overcomes the elastic force of the spring 1702 and slides along the slide groove 5, releasing the limiting force on the protective plate 3. All structures work closely together to meet the detection requirements and provide a variety of convenience and protection functions.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
