[0025] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] As attached Figure 1-12 A flip-top quick-ventilation filter shown in the figure comprises a bottom box 1, a cover 2 and a filter structure 3, wherein the outer side surfaces on the left and right sides of the bottom box 1 are symmetrically provided with front clamping columns 4 and rear clamping columns 5, which are respectively arranged at the front end and the rear end of the outer side surface of the bottom box 1, and the thickness of the upper half of the rear clamping column 5 gradually increases from top to bottom, so that the upper half of the rear clamping column 5 forms a guiding inclined surface 6, which can facilitate the rear clamping column 5 to be clamped into the rear clamping groove 8; the inner side surfaces on the left and right sides of the cover 2 are symmetrically provided with front clamping grooves 7 and rear clamping grooves 8, and the front clamping grooves 7 and the rear clamping grooves 8 are both "7". shaped structure; the front clamping column 4 and the front clamping groove 7 on the same side are slidably matched, one end of the front clamping groove 7 is parallel to the bottom edge of the face cover 2 and extends forward, and the other end of the front clamping groove 7 extends to the bottom edge of the face cover 2 and is provided with an opening 9; the rear clamping column 5 and the rear clamping groove 8 on the same side are slidably matched, one end of the rear clamping groove 8 is parallel to the bottom edge of the face cover 2 and also extends forward, and the other end of the rear clamping groove 8 extends to the bottom edge of the face cover 2 and is provided with an arc seal 10 that rotates matching the rear clamping column 5, the filter structure 3 is a dense metal mesh that is bent back and forth up and down and is arranged in the bottom box 1, and the edges of the filter structure 3 are in contact with the inner wall of the bottom box 1. The front end of the base box 1 is provided with two locking blocks 11 extending forward, and the two locking blocks 11 are symmetrical to each other. The front end of the surface cover 2 is provided with two locking slots 12 which correspond to the locking blocks 11 one by one and are inserted in a matching manner. The locking slots 12 and the locking blocks 11 cooperate to fix the front end of the surface cover 2 to the front end of the base box 1.
[0027] As a preferred embodiment, the outer side surfaces on the left and right sides of the cover 2 are symmetrically provided with concave and convex patterns 13 protruding outward and extending up and down, so that the cover 2 can be easily slid out through the concave and convex patterns 13. The outer side surfaces on the left and right sides of the bottom box 1 are respectively provided with two mounting buckles 14 for fixing the bottom box 1 to the cabinet. The mounting buckles 14 protrude outward and the upper surface of the mounting buckles 14 is provided with four steps 15 gradually descending outward. The mounting steps 15 can adapt to cabinet cover plates of different thicknesses, thereby improving the versatility of the filter screen; the left and right sides of the lower surface of the cover 2 are provided with leakproof baffles 16 for covering the gap at the mounting buckles 14, so as to prevent airflow from flowing out or in from the mounting buckles 14 and affecting the filtering effect.
[0028] The ventilation filter provided in this embodiment is installed on the top of the electrical cabinet and used in conjunction with the exhaust fan. When the cover 2 needs to be opened, the cover 2 is moved forward by hand to disengage the locking block 11 from the locking slot 12. At the same time, the front clamping column 4 and the rear clamping column 5 move to the turning point of the front clamping slot 7 and the rear clamping slot 8, and the cover 2 can be flipped open.
