[0022] The following will be combined with the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 The hydrogen-oxygen mixed concentration detection device described in this embodiment includes a detector body 1 and a collection part 2 arranged on the surface of the detector body 1. A protective component for sealing and protecting the collection part 2 is provided on the outside of the detector body 1 and on one side of the collection part 2. The protective component includes a frame 3 fixedly connected to the detector body 1, two sliders 5 symmetrically slidably connected inside the frame 3, a baffle 4 fixedly connected between the two sliders 5, and four first magnet members 6, wherein two first magnet members 6 are respectively fixedly connected to the tops of the two sliders 5, and the other two first magnet members 6 are symmetrically fixedly connected to the top of the inner wall of the frame 3. The baffle 4 can be upward. The sliding drives the first magnet part 6 on the slider 5 to cooperate with the first magnet part 6 on the top of the inner wall of the frame 3 to be adsorbed; specifically, the closed structure formed by the detector body 1, the frame 3 and the baffle 4 can protect the collection part 2 to prevent the dust and impurities accumulated in the collection part 2 from affecting the normal entry of the hydrogen-oxygen mixed gas. When detection is required, the baffle 4 can be pushed upward to make the slider 5 slide inside the frame 3. The slider 5 moves upward so that the first magnet part 6 on the top is attracted to the first magnet part 6 inside the frame 3 to position the baffle 4, so that the hydrogen-oxygen mixed gas can be introduced through the collection part 2 for detection. The operation is simple and easy to use.

[0024] Reference Figure 1 , Figure 5 and Figure 6 A support plate 9 is rotatably connected to the rear side of the detector body 1 near the middle, and the support plate 9 can be rotatably connected to the detector body 1 to form a triangular structure. The support plate 9 is rotated to a certain angle to support the detector body 1, so that the detector body 1 can be placed at an angle, which is beneficial for users to observe the detection data. Two third magnet members 12 are symmetrically fixedly connected to the side of the support plate 9 close to the detector body 1 and the outside of the detector body 1; specifically, when the support plate 9 is in contact with the detector body 1, the third magnet member 12 on one side is driven to be attracted and connected to the third magnet member 12 of the detector body 1, which can ensure the stability of the connection between the support plate 9 and the detector body 1 and avoid shaking of the support plate 9.

[0025] Reference Figure 3 The bottom of the two sliders 5 and the bottom of the inner wall of the frame 3 are fixedly connected with second magnets 7 that attract each other. Specifically, when the baffle 4 covers the front of the collecting part 2, the second magnet 7 at the bottom of the slider 5 and the second magnet 7 located directly below are attracted to each other, so that the slider 5 can be more tightly connected to the frame 3, thereby ensuring the stability of the connection between the slider 5 and the frame 3.

[0026] Reference Figure 1 , Figure 4 and Figure 5Two anti-slip parts 10 are symmetrically fixedly connected on both sides of the detector body 1. The anti-slip parts 10 can be made of rubber with protrusions to facilitate the user to better hold the detector body 1 for use. A connecting rope 11 is connected to the top of the detector body 1. The set connecting rope 11 can be convenient for the user to hold and carry. A pull block 8 is fixedly connected to the outer side of the baffle 4 near the top and on the side opposite to the collection part 2. The raised pull block 8 facilitates the operation of the baffle 4 to move upward.

[0027] The working principle of the utility model is as follows: the closed structure formed by the detector body 1, the frame 3 and the baffle 4 can protect the collection part 2 to prevent the dust and impurities accumulated in the collection part 2 from affecting the normal entry of the hydrogen-oxygen mixed gas. When detection is required, the baffle 4 can be pushed upward to make the slider 5 slide inside the frame 3. The slider 5 moves upward to make the first magnet part 6 on the top attract the first magnet part 6 inside the frame 3 to position the baffle 4, so that the hydrogen-oxygen mixed gas can be introduced through the collection part 2 for detection. The operation is simple and easy to use.
