More and more industrial waste gas, vehicle exhaust, and harmful substances from the combustion of various fuels are being emitted into the atmosphere, making the air environment on which we depend for survival increasingly worrying. Among them, odor pollution has become increasingly serious in my country.

[0003] When detecting odor pollution, portable odor detectors are usually used to detect the gas. However, most portable odor detectors need to be moved around for testing, and they are easily bumped and knocked during transportation, resulting in poor protection. After being bumped and knocked, the accuracy of the detection is easily affected, which is not conducive to use. Therefore, a portable odor detector is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 This embodiment of a portable odor detector includes a protective box 1. The top of the protective box 1 is hinged to a cover plate 2. The protective box 1 can protect the detector 9 inside, thereby making the whole more stable. A sealing strip is fixed to the front of the protective box 1. A sealing groove adapted to the sealing strip is opened at the bottom of the cover plate 2. The sealing strip and sealing groove can improve the sealing performance of the connection between the protective box 1 and the cover plate 2, thereby further improving the overall stability. A hinge block 3 is fixed to the front of the cover plate 2. A fixing component is hinged inside the hinge block 3. The fixing component includes a fixing block 4 hinged to the hinge block 3. A rotating rod 5 is threaded inside the fixing block 4. A threaded strip is fixed to the outer surface of the rotating rod 5. A threaded hole adapted to the threaded strip is opened inside the fixing block 4. Because the rotation of the fixing block 4 is restricted, when the rotating rod 5 is rotated, the rotating rod 5 will move due to the compression of the thread, thereby making the engagement between the fixing hook 6 and the support block 7 more stable.

[0022] In addition, a fixed hook 6 is rotatably connected to the bottom of the rotating rod 5. A bearing is fixed to the bottom of the rotating rod 5, and the inside of the bearing is fixed to the fixed hook 6. The fixed hook 6 can rotate through the bearing, so that after the fixed hook 6 and the rotating rod 5 rotate, the fixed hook 6 can be reset, thus ensuring the stability of the fixation. A control block is fixed to the top of the rotating rod 5. The control block makes it easier to push the rotating rod 5 to rotate, thus making the whole more practical. A support block 7 is fixed to the bottom of the protective box 1. The support block 7 is inserted into the fixed hook 6 to fix the cover plate 2 and the protective box 1. The fixing assembly is used to fix the cover plate 2 and the protective box 1.

[0023] Furthermore, a shock-absorbing assembly 8 is installed between the left and right side walls of the inner cavity of the protective box 1. A detector 9 is fixed to the front of the shock-absorbing assembly 8. The detector 9 is used to analyze the gas. In addition, a storage battery is fixed inside the detector 9. A caster wheel 10 is fixed to the top of the protective box 1. The caster wheel 10 makes the whole unit easy to move. A sensor gun 11 is fixed to the inner bottom wall of the protective box 1. The sensor gun 11 includes a gun handle fixed to the protective box 1. A gas tube is connected to the right side of the gun handle, and a flexible tube is connected to the left side of the gun handle. The sensor gun 11 makes it easier to draw the gas to the detector 9.

[0024] In summary, by attaching the cover plate 2 and the protective box 1 together, and by rotating the fixing block 4, the hook of the fixing hook 6 can be positioned below the support block 7. By holding the fixing hook 6 and rotating the rotating rod 5, the fixing hook 6 and the rotating rod 5 can be moved together, thereby engaging the fixing hook 6 with the support block 7, thus effectively fixing the cover plate 2 and the protective box 1, making the internal detector 9 more stable.

[0025] Please see Figure 2-3 To improve overall protection, the shock absorption assembly 8 in this embodiment includes two movable plates 801 fixed to the protective box 1. Each movable plate 801 has a shock-absorbing spring 802 fixed on one side opposite to the other. The shock-absorbing springs 802 are used to buffer vibrations, thereby making the whole more stable. Each movable plate 803 is fixed on one side opposite to the other and is slidably connected to the movable plate 801. The slidable plate 803 is fixed to the detector 9, and the detector 9 is fixed to the slidable plate 803, so that the detector 9 is not easy to shake. Each slidable plate 804 is fixed on one side opposite to the other. A connecting block 805 is fixed between the two connecting plates 804. A sliding block is fixed on the top of the detector 9. A sliding groove is opened at the bottom of the connecting block 805 and is slidably connected to the sliding block.

[0026] In summary, when vibration occurs, the movable plate 801 slides inside the stabilizing plate 803, allowing the shock-absorbing spring 802 to buffer the vibration. The overall structure is simple, effectively improving the overall protection and making the whole system more stable.

[0027] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply provided by the storage battery is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0028] The working principle of the above embodiments is as follows:

[0029] By attaching the cover plate 2 to the protective box 1, the protective box 1 can effectively protect the detector 9, thereby making the internal detector 9 more stable. When it encounters an impact and vibration, the moving plate 801 will slide inside the stabilizing plate 803, so that the shock-absorbing spring 802 can effectively buffer the vibration. The connecting plate 804 can fix the two stabilizing plates 803 together, so that the two shock-absorbing springs 802 assist each other in buffering. The overall structure is simple and effectively improves the overall protection, thus making the whole more stable.
