[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0027] Example 1: This utility model provides the following... Figures 1-7 As shown, an alcohol breathalyzer device includes: an alcohol detector 1, wherein the air inlet of the alcohol detector 1 is provided with a positioning ring 2;

[0028] Installation tube 3, one end of which has a threaded groove 4, and the other end of which is inserted into the air inlet 5;

[0029] A transparent tube 6 has a movable groove 7 on its inner side, a limit ring 25 at one end of the transparent tube 6, and an installation ring 8 at the other end of the transparent tube 6.

[0030] Mounting plate 9, a first bearing 10 is provided on the side of mounting plate 9, a rotating rod 11 is provided inside the first bearing 10, a fixed sleeve 12 is sleeved on the surface of the rotating rod 11, a paddle 13 is provided on the surface of the fixed sleeve 12, and a fluorescent strip 14 is provided on the surface of the paddle 13.

[0031] In use, a lever 13 is installed inside the transparent tube 6, and a fluorescent strip 14 is installed on the end face of the lever 13. When the driver blows into the air inlet 5, the lever 13 can rotate in conjunction with the first bearing 10 and the rotating rod 11, making it easy for inspectors to observe whether the driver is blowing seriously. Then, the alcohol detector 1 can be used to observe whether the driver has drunk driving problems. When checking for drunk driving at night, the fluorescent strip 14 on the surface of the lever 13 can be used to observe whether the lever 13 is rotating, so as to make it easy to judge whether the driver is blowing hard for the test.

[0032] Example 2: Figure 1-3 As shown, more specifically, in order to facilitate the protection of the air inlet of the alcohol detector 1 when it is not in use, a protective cover 17 is provided. The inner ring surface of the positioning ring 2 is threaded, and a damping bearing 15 is provided on the surface of the positioning ring 2. A positioning rod 16 is fixedly connected to the inner ring surface of the damping bearing 15. A protective cover 17 is provided on the surface of the positioning rod 16. The protective cover 17 can cover the surface of the positioning ring 2.

[0033] When the alcohol detector 1 is not needed, the limiting ring 25 can be screwed out from the inner screw of the positioning ring 2. Then, the protective cover 17 can be rotated in conjunction with the damping bearing 15. This allows the protective cover 17 to cover the top of the positioning ring 2, thus preventing large external objects from entering the alcohol detector 1. The damping bearing 15 also prevents the protective cover 17 from rotating arbitrarily.

[0034] To facilitate the connection between the transparent tube 6 and the alcohol detector 1, a limiting ring 25 is provided. The outer ring surface of the limiting ring 25 is also threaded. The limiting ring 25 can be screwed into the positioning ring 2. The outer ring surface of the mounting ring 8 is provided with a second thread. The mounting ring 8 is screwed into the threaded groove 4. The limiting ring 25 can be directly screwed into the positioning ring 2. Then, the mounting ring 8 is screwed into the threaded groove 4, which allows the mounting tube 3 to be connected to the transparent tube 6 and is also easy to disassemble. The air inlet 5 is a disposable product. After the driver uses it for testing, the air inlet 5 can be directly pulled out and replaced.

[0035] Example 3: Figure 1 and Figure 7As shown, more specifically, in order to facilitate the driver's use of air to avoid not blowing air during the test, a paddle 13 is provided. The rotating rod 11 is fixedly connected to the inner ring surface of the first bearing 10. Multiple sets of paddles 13 are provided, and the multiple sets of paddles 13 are arranged in a regular circular pattern about the fixing sleeve 12. The fluorescent strip 14 is glued to the surface of the paddle 13.

[0036] When the driver blows air into the air intake 5, the paddle 13 can rotate in conjunction with the first bearing 10, so that the inspection personnel can easily observe the rotation of the paddle 13 through the transparent tube 6 to determine whether the driver has blown air. The fluorescent strip 14 makes it convenient for the paddle 13 to be used at night.

[0037] Example 4: Figure 5 and Figure 6 As shown, more specifically, for the convenience of installing the paddle 13, a lifting rod 22 is provided. The moving groove 7 is in the shape of a "T" plate. A positioning groove 18 is opened on the surface of the moving groove 7. A moving block 19 is provided on the outer side of the mounting plate 9. The moving block 19 is in the shape of a "T" plate. The moving block 19 is inserted into the moving groove 7. A lifting groove 20 is opened on the side of the mounting plate 9. The lifting groove 20 passes through the side of the moving block 19. A base plate 21 is provided in the lifting groove 20. A through hole is opened on the surface of the base plate 21. The lifting rod 22 is inserted into the through hole. One end of the lifting rod 22 is inserted into the positioning groove 18. A return spring 23 is sleeved on the surface of the lifting rod 22. A pull plate 24 is provided on the end face of the lifting rod 22. One end of the return spring 23 is fixedly connected to the bottom of the pull plate 24. The other end of the return spring 23 is fixedly connected to the surface of the base plate 21.

[0038] In use, first pull the pull plate 24 to move the lifting rod 22 upward. Then, the moving block 19 can be moved along the moving groove 7. When the moving block 19 is moved to the appropriate position, the pull plate 24 can be released, so that the lifting rod 22 can be reset by the elastic force of the return spring 23. This makes it easy to insert one end of the lifting rod 22 into the positioning groove 18. The moving block 19 can then be fixed in conjunction with the positioning groove 18 and the moving groove 7, thus making it easy to fix and install the mounting plate 9.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
