[0024] Please refer to Figures 1 to 7The figure shows a split-type electric saw with a filter installed, which is mainly designed with components such as a body 1, an inner lining 2, a filter 3, and an outer cover 4. The body 1 is used as an installation and fixing platform for other components. The inner lining 2 is used to be fixed on the body 1 to facilitate the fixation of the filter 3. The filter 3 is installed at the vent 5 of the inner lining 2 to play a filtering role. The outer cover 4 is used to cooperate with the body 1 to fix the lining 2. In actual applications, the shapes and structures of the above components can be optimized or other components can be added.

[0025] The main structure of the fuselage 1 in the figure is consistent with the existing ones, except that the positions matching the inner lining 2 and the outer cover 4 are optimized as shown in the figure. In the figure, the fuselage 1 has a convex fixing part 11, which has components such as a motor and a suction fan inside. The outer wall of the inner fixing part is punched at the position facing the filter 3 to form a vent 5. As shown in the figure, there are two groups of holes in each group, one on the upper and one on the left. The shape of the vent 5 is a trapezoidal structure, thereby expanding the air intake; the outer wall of the inner fixing part, that is, the side edge 12, keeps corresponding to the inner edge shape of the inner lining 2 at other positions. As shown in the figure, a straight edge 121 and other structures are designed to facilitate the positioning and installation of the inner fixing part and the inner lining 2.

[0026] The main body of the liner 2 in the figure is a structure similar to a round cover, and the same vent 5 is designed and aligned with the position of the vent 5 on the inner fixed part of the fuselage 1. The liner 2 is sleeved on the inner fixed part of the fuselage 1. The liner 2 is designed with an inwardly concave groove 21 structure at two symmetrical positions at the top and bottom. This shape corresponds to the filter 3 so that the filter 3 can be placed in the groove 21 and the mounting hole 31 of the filter 3 can be matched with screws to achieve mutual fixation. The above-mentioned liner 2 protrudes outward at the middle horizontal position to form a protrusion 22 structure, and the outer cover 4 is designed at the corresponding position with a hollow groove 41 that can be fixedly matched with the protrusion 22, so that the liner 2 is embedded in the outer cover 4 at this position, thereby strengthening the mutual assembly strength of the two components. In order to improve the assembly effect, the above-mentioned lining 2 is symmetrically designed with a total of four buckle grooves 23 structures on the upper and lower edges of the protrusion 22, and the outer shell 4 is correspondingly designed with four buckles 42 that can cooperate with the buckle grooves 23 to form buckles 42. In this way, a total of two groups of buckle grooves 23 and two groups of buckles 42 are assembled with each other.

[0027] The main body shape of the filter 3 in the figure is a conventional filter 3 structure, which has filter holes, and the shape remains corresponding to the shape of the vent 5. As shown in the figure, the filter 3 has two and is arranged symmetrically up and down.

[0028] The outer cover 4 in the figure is fixed on the fuselage 1 as a whole by screws, and a vent 5 is also designed thereon. At the same time, the protruding part in the figure corresponds to the shape of the inner fixing part on the fuselage 1 so as to accommodate the inner fixing part and the lining 2.
