[0027] See also Figure 1-4 As shown, in this embodiment, an air heating filter for a photocurable 3D printing device is provided, comprising a housing 1, a honeycomb hole cover plate 8 clamped on the side of the housing 1, and an air heating component installed in the housing 1, wherein filter cotton 7 is placed in the honeycomb hole cover plate 8, and the filter cotton 7 is located between the honeycomb hole cover plate 8 and the housing 1, and an upper plug block 801 is provided on the upper side of the honeycomb hole cover plate 8, and two lower clamping blocks 802 are provided on the lower side;
[0028] A slot corresponding to the upper plug block 801 is provided on the shell 1, and a limiting groove 103 corresponding to the lower clamping block 802 is provided on one side of the shell 1. The lower clamping block 802 is located in the limiting groove 103. Two baffles 2 are elastically fitted in the shell 1. The upper part of the baffle 2 is located in the limiting groove 103. An extension plate 201 is installed at the lower part of one side of the baffle 2. The two extension plates 201 are located between the two baffles 2. A pull column 202 is installed at the end of the extension plate 201 away from the baffle 2.
[0029] The application of one aspect of this embodiment is as follows: when in use, the air heating component draws in outside air from the honeycomb hole cover plate 8, and after filtering it through the filter cotton 7, the air is heated by the air heating component, and finally the hot air is transported from the bottom of the shell 1 into the light-curing 3D printing device. When the filter cotton 7 needs to be replaced, the two pull columns 202 are pinched to move closer to each other, and the pull column 202 pulls the baffle 2 to slide through the extension plate 201, so that the part of the baffle 2 located in the limiting groove 103 is received into the shell 1, so that the baffle 2 cancels the limit on the lower block 802, and then force is applied to the lower part of the honeycomb hole cover plate 8, so that the honeycomb hole cover plate 8 drives the lower block 802 to tilt out of the limiting groove 103, and then the upper insert block 801 is drawn downward into the slot, so that the honeycomb hole cover plate 8 together with the filter cotton 7 is removed. After replacing the filter cotton 7, refer to the above operation to quickly install the honeycomb hole cover plate 8.
[0030] A placement groove 101 corresponding to the honeycomb hole cover plate 8 is provided on one side of the shell 1 of the present embodiment. The placement groove 101 passes through the shell 1 horizontally.

The width of the baffle 2 is greater than the width of the limiting groove 103 and less than the width of the receiving groove 104. When the pull column 202 is pulled, the pull column 202 pulls the baffle 2 to slide through the extension plate 201, so that the part of the baffle 2 located in the limiting groove 103 is completely received in the receiving groove 104. At the same time, the baffle 2 slides to squeeze the spring 203, so that after the pull column 202 is released, the baffle 2 drives the extension plate 201 and the pull column 202 to quickly reset.
