[0025] Further, the reset assembly 8 includes a fixed column 801, a movable column 802 and a spring 803. The outer side of the first filter plate 601 is located on the inner wall of the sleeve 1 and is fixedly connected to the fixed column 801. The movable column 802 is movably connected inside the fixed column 801. The upper end of the movable column 802 is fixedly connected to the second filter plate 605.

Figure 3 As shown, the structure is used to drive the connecting plate 701 to rotate through the movable sleeve 604, and to clean the impurities remaining on the surfaces of the first filter plate 601 and the second filter plate 605 through the first scraper 702 and the second scraper 703.

[0028] Furthermore, two sets of guide grooves 9 are provided on both sides of the movable rod 602, and a hole matching the movable rod 602 is provided on the inner side of the second filter plate 605. Two sets of protrusions are fixedly connected to the inner wall of the hole, and the diameter of the protrusions matches the guide grooves 9. Figure 3 As shown, this structure is used through the cooperation of the guide groove 9 and the protrusion. When the movable sleeve 604 drives the second filter plate 605 to move downward, the second filter plate 605 moves stably downward in the guide groove 9 through the protrusion, thereby improving the stability of the device.

[0029] Furthermore, the filter holes 606 on the surfaces of the first filter plate 601 and the second filter plate 605 are staggered, the latch 607 is conical, the latch 607 on the upper surface of the first filter plate 601 corresponds to the filter hole 606 on the second filter plate 605, and the latch 607 at the lower end of the second filter plate 605 corresponds to the filter hole 606 on the surface of the first filter plate 601. Figure 3 As shown, the structure is used to insert the pin 607 at the lower end of the second filter plate 605 into the filter hole 606 at the first filter plate 601, keeping the filter hole 606 clean and unblocked, and the operation is simple and convenient, reducing the impact of impurities on the normal use of the flame arrester.

[0030] Furthermore, the edge of the knob 603 is provided with a 2 mm anti-slip groove, and the center of the knob 603 is provided with a connection groove. Figure 3 As shown, this structure is used to enhance the anti-slip effect through the anti-slip grooves at the edge of the knob 603, and the depth of two millimeters can be used to ensure that the anti-slip grooves still have an anti-slip effect after a certain degree of wear. The connecting groove is convenient for connection with external devices, thereby facilitating driving of the knob 603.

[0031] Working principle: When used, Figure 1 and Figure 2 As shown, when air circulates inside the sleeve 1, the air first contacts the first filter plate 601 and the second filter plate 605, and most of the impurities in the air are blocked by the first filter plate 601 and the second filter plate 605, thereby reducing the probability of impurities entering the sleeve 1. When the first filter plate 601 and the second filter plate 605 are blocked particularly severely, as shown in FIG. Figure 2 and Figure 4 As shown, the knob 603 is turned to make the movable sleeve 604 push the second filter plate 605 to move downward and fit with the first filter plate 601. The second filter plate 605 moves downward stably in the guide groove 9 through the protrusion. When the second filter plate 605 moves downward, it drives the movable column 802 to move in the fixed column 801, squeezes the spring 803, and deforms the spring 803. At this time, the latch 607 at the lower end of the second filter plate 605 is inserted into the filter hole 606 at the first filter plate 601, and the latch 607 at the upper end of the first filter plate 601 is inserted into the filter hole 606 at the second filter plate 605 to keep the filter hole 606 clean and not blocked. Figure 3As shown, while the knob 603 is rotated, the movable sleeve 604 drives the connecting plate 701 to rotate, and the impurities remaining on the surfaces of the first filter plate 601 and the second filter plate 605 are cleaned by the first scraper 702 and the second scraper 703. After cleaning, the knob 603 is rotated in the opposite direction. When the movable sleeve 604 rises, the second filter plate 605 is pushed to fit the lower side of the movable sleeve 604 under the rebound action of the spring 803, so that the second filter plate 605 is restored to its original position, which is convenient for strengthening the connection between the second filter plate 605 and the movable sleeve 604 and forming a double-layer filtering mechanism at the same time, so that the filtering effect is better. The above is the entire working principle of the utility model.
