Description

Technical Field

[0001] The utility model relates to the field of air filter leakage prevention, in particular to a leakage prevention mechanism for an air filter. Background Art

[0002] Air filters often use leak-proof mechanisms to ensure their effectiveness and performance. These leak-proof mechanisms are designed to prevent unfiltered air from bypassing the filter and entering. They are generally equipped with sealing gaskets, which are used at the filter edges or interfaces to ensure the seal between the filter and the installation location. They are also equipped with sliding clamps or limit devices to fix the filter by using clamps or card limit devices to ensure its tight fit and prevent air from bypassing the filter medium.

[0026] Reference Figure 1-Figure 4The utility model provides a technical solution: an anti-leakage mechanism for an air filter, comprising a limiting frame 2, an anti-leakage device 1 and a sealing tube 26. The anti-leakage device 1 is a mechanism that can make the air filter body 3 fully anti-leakage sealed, thereby realizing the self-sealing of the air filter body 3, and no deviation will occur. The anti-leakage device 1 comprises two groups of mounting blocks 11, a fixing rod 12 is inserted into the interior of the mounting block 11, a first gear 14 and two groups of second gears 17 are arranged on the surface of the fixing rod 12, a tooth plate 15 is arranged at the bottom of the first gear 14, and a mounting plate 18 is arranged above the two groups of second gears 17, a first air bag 16 is arranged on one side of the tooth plate 15, and a second air bag 19 is arranged on one side of the mounting plate 18, through the air filter body 3, the fixing rod 12, the first gear 14, the second gear 17, the first gear 14 and the second gear 17. The mutual cooperation of the first airbag 16, the second airbag 19 and the air pump 25 allows the operator to first turn the crank 28 when the operator needs to perform a leak-proof seal on the air filter body 3. The crank 28 drives the fixed rod 12 to rotate. When the fixed rod 12 rotates, it also drives the first gear 14 and the second gear 17 to rotate. The first gear 14 drives the tooth plate 15 to move inside the slide groove 32, and the second gear 17 drives the teeth 21 on the mounting plate 18 to rotate, so that the first airbag 16 and the second airbag 19 move toward each other. When the movement is completed, the operator can use the air pump 25 to inflate the first airbag 16 and the second airbag 19 to make the air filter body 3 fully leak-proof and sealed, thereby achieving self-sealing of the air filter body 3 without any deviation.

[0027] Reference Figure 1-Figure 4 In a preferred embodiment, a sealing tube 26 is arranged inside one side of the limiting frame 2, a sealing ring 29 is arranged inside the other side of the limiting frame 2, a tooth 21 is arranged at the bottom of the mounting plate 18, the tooth 21 is meshed and connected with the second gear 17, the tooth plate 15 is meshed and connected with the first gear 14, a mounting frame 13 is arranged at the top of the limiting frame 2, a slide groove 32 is opened inside the mounting frame 13, and the tooth plate 15 can slide inside the slide groove 32 by opening the slide groove 32, the tooth plate 15 is arranged inside the slide groove 32, an air filter body 3 is arranged inside the limiting frame 2, and the air filter body 3. The groove 31, the sealing ring 29, the limiting groove 23, the sealing tube 26, the first airbag 16 and the second airbag 19 cooperate with each other, so that when the operator needs to improve the leak-proof sealing effect of the air filter body 3, the operator sets the sealing ring 29 inside the groove 31 and the sealing tube 26 inside the limiting groove 23, so that when the first airbag 16 and the second airbag 19 inflate the air filter body 3, they can conflict with the sealing ring 29 and the sealing tube 26, which can improve the leak-proof sealing effect of the air filter body 3 and completely cover the gap at the joint, which is convenient for the operator to use.

[0028] Reference Figure 1-Figure 4 In a preferred embodiment, a limiting frame 22 is provided on the top of the limiting frame 2. By providing the limiting frame 22, the position of the mounting plate 18 can be limited. The mounting plate 18 is arranged inside the limiting frame 22. A limiting groove 23 is provided on one side of the limiting frame 2. A sealing tube 26 is provided inside the limiting groove 23. A groove 31 is provided on the other side of the limiting frame 2. A sealing ring 29 is provided inside the groove 31. An inflation tube 24 is provided on the opposite side of the mounting plate 18 and the tooth plate 15. By providing the inflation tube 24, the first air bag 16 and the second air bag 19 can be inflated with the air pump 25. An air pump 25 is provided on both sides of the limiting frame 2. A crank 28 is provided at one end of the fixing rod 12. By providing the crank 28, the operator can easily rotate the fixing rod 12. An observation window 27 is provided on one side of the limiting frame 2. By providing the observation window 27, the air filter body 3 inside the limiting frame 2 can be observed.

[0029] Specifically, the working process or working principle of the leakage prevention mechanism for an air filter is as follows: in the specific leakage prevention of the air filter, although the conventional air filter can perform leakage prevention operations, it lacks the ability to adjust its self-sealing properties, and the leakage prevention mechanism may become loose or offset during use, and cannot completely cover the gaps at the joints, making it inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to perform leakage prevention and sealing on the air filter body 3, the operator can first turn the crank 28, and the crank 28 drives the fixed rod 12 to rotate. When the fixed rod 12 rotates, it also drives the first gear 14 and the second gear 17 to rotate. The first gear 14 drives the tooth plate 15 to move inside the slide groove 32, and the second gear 17 drives the teeth 21 on the mounting plate 18 to rotate, so as to prevent the air filter body 3 from leaking. This causes the first airbag 16 and the second airbag 19 to move toward each other. When the movement is completed, the operator can use the air pump 25 to inflate the first airbag 16 and the second airbag 19 to make the air filter body 3 fully leak-proof and sealed, thereby achieving self-sealing of the air filter body 3 without deviation. When the operator needs to improve the leak-proof sealing effect of the air filter body 3, the operator sets a sealing ring 29 inside the groove 31 and a sealing tube 26 inside the limiting groove 23, so that when the first airbag 16 and the second airbag 19 inflate the air filter body 3, they can conflict with the sealing ring 29 and the sealing tube 26, thereby improving the leak-proof sealing effect of the air filter body 3 and completely covering the gap at the joint, which is convenient for the operator to use. At this point, all processes are completed.

[0030] It should be noted that the air filter body 3 and the air pump 25 are both electrically connected to an external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
