Specific implementation

[0025] Below, some implementation of the utility model are explained in detail in combination with the drawings. In the case of no conflict, the following embodiment and the features in the embodiment can be combined mutually.

[0026] Please refer to Figures 1-6 The utility model embodiment provides a central air conditioning filter device, including air conditioner body 1 and air deflector 2 outside the air outlet of air conditioner body 1, the four corners at the air outlet of air conditioner body 1 are all provided with clamping hole 8, and the inside of air deflector 2 is provided with protruding block clamping cooperation, therefore, it is convenient to disassemble air deflector 2, thereby being convenient to clean filter screen 15 inside.

[0027] The symmetrical sliding groove 3 is set up on the inner wall of both sides of the air outlet of air conditioner body 1, and the positioning piece is slidably installed in each sliding groove 3, and the two symmetrical positioning pieces are fixed to the two sides of filter screen 15 respectively, and filter screen 15 is moved out of air conditioner body 1 by the downward sliding of positioning piece.

[0028] Specific, positioning member includes sliding in the sliding slot 3 sliding plate 9, the upper and lower ends of the sliding plate 9 are provided with through slot 10, two groups of through slot 10 are slidably installed with positioning plate 12, the lower side of the positioning plate 12 is provided with positioning block 13, the positioning block 13 passes through the recess 18 formed in the side wall of the filter screen 15, is inserted into the perforation 19, fixes the filter screen 15, improves the stability of the filter screen 15, the filter screen 15 can be moved out of the air conditioner body 1 by sliding the sliding plate 9 in the sliding slot 3.

[0029] In order to make the sliding plate 9 not separate from the sliding slot 3, the sliding block 11 is arranged on both sides of the upper end of the sliding plate 9, and the sliding block 11 is slidably arranged in the limiting groove 4 formed in the inner wall of the sliding slot 3 on both sides, and the movement distance of the sliding plate 9 is limited by the limiting groove 4.

[0030] In addition, the spring 14 is arranged in the through slot 10, one end of the spring 14 is connected with the positioning plate 12, in the natural state, the spring 14 abuts against the positioning plate 12, so that the positioning plate 12 is fixed more stably, and when the filter screen 15 is disassembled, the positioning plate 12 can be slid outward to extrude the spring 14, so that the positioning plate 12 is separated from the perforation 19, at this time, the filter screen 15 is convenient to disassemble, and the filter screen 15 can be cleaned or replaced.
