[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A dual-purpose portable display case for automotive air filters includes:

[0027] A transparent box 1 with a rotating handle at the top is provided. Two first sealing covers 2 and two second sealing covers 4 are symmetrically distributed at the top of the transparent box 1. Each of the two first sealing covers 2 has an inlet plate 3 at the top and each of the two second sealing covers 4 has a detection plate 5 at the top. A fixing mechanism 8 for fixing the filter element is provided at the bottom of the transparent box 1.

[0028] For example, the front of the transparent box 1 is provided with a plurality of evenly distributed sealing doors 11. Opening the sealing doors 11 facilitates the installation and removal of the filter element. Acetic acid is sprayed into the interior of the transparent box 1 through the liquid inlet plate 3. After the airflow passes through the filter element, it passes through the detection plate 5 to smell the gas inside the transparent box 1 and detect the filtration effect of the filter element. The first sealing cover 2 and the second sealing cover 4 are both installed with bolts, which facilitates the removal of the first sealing cover 2 and the second sealing cover 4. When not in use, the filter element can be stored.

[0029] The fixing mechanism 8 includes a screw 81, a rotating ring 82, a lifting block 83, a rubber shell 85, a connecting rod 86, a lifting frame 87, a rubber frame 88, and an auxiliary support assembly 89;

[0030] The transparent box 1 has two symmetrically distributed screws 81 at its inner bottom. A rotating ring 82 is fixedly connected to the outer side of the screws 81. A lifting block 83 is threadedly connected to the upper end of the screws 81. Two symmetrically distributed telescopic rods 84 are provided at the lower end of the lifting block 83. The telescopic rods 84 are fixedly connected to the transparent box 1. A rubber shell 85 is fixedly connected to the outer side of the lifting block 83. Two symmetrically distributed connecting rods 86 are fixedly connected to the side wall of the rubber shell 85. A lifting frame 87 is provided at the upper end of the connecting rod 86. A rubber frame 88 is fixedly connected to the upper end of the lifting frame 87. An auxiliary support assembly 89 for supporting the filter element is provided on the outer side of the connecting rod 86.

[0031] For example, the screw 81 is rotated by the rotating ring 82. When the screw 81 rotates, a threaded motion occurs between it and the lifting block 83, controlling the lifting block 83 to rise and fall. The rubber shell 85 on the outside of the lifting block 83 cooperates with the transparent frame 9 to fix the cylindrical filter element. When the lifting block 83 rises and falls, the lifting frame 87 and the rubber frame 88 are driven to rise and fall through the connecting rod 86. The rubber frame 88 fixes the square filter element. When the lifting block 83 rises and falls, the telescopic rod 84 extends and retracts to guide the lifting block 83.

[0032] The auxiliary support assembly 89 includes a sliding frame 891, a fixing bolt 892, a fixing rod 893, a sliding rod 894, and a rubber strip 895;

[0033] A sliding frame 891 is slidably connected to the outer side of the connecting rod 86. A fixing bolt 892 is provided inside the sliding frame 891. The fixing bolt 892 contacts the connecting rod 86. A fixing rod 893 is fixedly connected to the upper end of the sliding frame 891. A sliding rod 894 is fixedly connected to the upper end of the fixing rod 893. Two symmetrically distributed sliders are fixedly connected to the side wall of the sliding rod 894. A sliding groove is provided on the inner wall of the lifting frame 87. The sliding groove is slidably connected to the slider. A rubber strip 895 is fixedly connected to the upper end of the sliding rod 894.

[0034] For example, by loosening the fixing bolt 892, the sliding frame 891 is slid on the outside of the connecting rod 86. The sliding frame 891 moves the sliding rod 894 and the rubber strip 895 through the fixing rod 893, which facilitates the fixing of square filter elements of different sizes. When the sliding frame 891 is fixed by the fixing bolt 892, the slider slides inside the slide groove when the sliding rod 894 moves, which guides and limits the sliding rod 894.

[0035] The transparent box 1 has two symmetrically distributed partitions 6 fixedly connected inside, and the partitions 6 have multiple symmetrically distributed ventilation holes 7 inside.

[0036] For example, two partitions 6 divide the transparent box 1 into multiple cavities. The cavities on both sides of the partitions 6 are connected by ventilation holes 7. The transparent box 1 without a fixing mechanism 8 has a smoke inlet hole on its side wall, and the transparent box 1 with a fixing mechanism has a wire inlet hole on its side wall to facilitate power supply to the fan 10.

[0037] The transparent box 1 has two symmetrically distributed transparent frames 9 fixedly connected inside, and a fan 10 is installed at the upper end of the transparent frame 9.

[0038] For example, the filtration effect of the filter element can be observed by observing the inside of the transparent frame 9. The fan 10 draws out the air inside the lower transparent frame 9. At the same time, two ventilation holes are opened inside the transparent frame 9. The recommended model of the fan 10 is DC centrifugal fan 10EBM-Papst 414F (24VDC, air volume 15CFM, noise 32dB).

[0039] Working principle: When using this utility model, the sealing door 11 is opened to facilitate the installation and removal of the filter element. The acetic acid is sprayed into the interior of the transparent box 1 through the liquid inlet plate 3. The airflow enters the cavity inside the transparent box 1 without the fixing mechanism 8. The fan 10 draws out the air inside the lower transparent frame 9 to form a negative air pressure. The airflow containing acetic acid enters the cavity where the fixing mechanism 8 is located through the ventilation hole 7 at the lower end of the partition 6. The filter element fixed at the upper end of the fixing mechanism 8 filters the airflow. After passing through the filter element, the airflow passes through the detection plate 5 to smell the gas inside the transparent box 1 to detect the filtration effect of the filter element. The airflow can also flow back into the cavity inside the transparent box 1 without the fixing mechanism 8 through the ventilation hole 7 at the upper end of the partition 6 to form an air circulation loop. Similarly, smoke is injected into the interior of the transparent box 1 through the smoke inlet to detect the filtration effect of the filter element on the smoke.

[0040] The screw 81 is rotated by the rotating ring 82. When the screw 81 rotates, a threaded motion occurs between it and the lifting block 83, controlling the lifting block 83 to rise and fall. The rubber shell 85 on the outside of the lifting block 83 cooperates with the transparent frame 9 to fix the cylindrical filter element. When the lifting block 83 rises and falls, the lifting frame 87 and the rubber frame 88 are driven to rise and fall through the connecting rod 86. The rubber frame 88 fixes the square filter element. Loosen the fixing bolt 892 and slide the sliding frame 891 on the outside of the connecting rod 86. The sliding frame 891 drives the sliding rod 894 and the rubber strip 895 to move through the fixing rod 893, which facilitates the fixing of square filter elements of different sizes.

[0041] The fan 10 in this application is controlled automatically by a controller. The controller circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect the structure, shape and its combination, the control method and circuit connection will not be explained in detail. The device is powered by a built-in power supply or an external power supply.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
