CONCRETE IMPLEMENTING METHOD

[0021] ​The application will be described in further detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application, and those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0022] With reference to the drawings accompanying the specification Figures 1-5 An oil fume filter screen comprises an inner oil screen 1, a middle oil screen 2 and an outer oil screen 3 installed in sequence, and a plurality of oil blocking strips one 11, oil blocking strips two 21 and oil blocking strips three 31 are arranged side by side on the inner oil screen 1, the middle oil screen 2 and the outer oil screen 3 respectively, the oil blocking strips one 11 and the oil blocking strips two 21 are arranged alternately, and the oil blocking strips two 21 and the oil blocking strips three 31 are arranged alternately.

[0023] As Figure 5 shown is the arrangement form of the oil blocking strips one 11, the oil blocking strips two 21 and the oil blocking strips three 31, and the arrow shown is the oil fume flow path, that is, the oil fume first flows into the position between the oil blocking strips two 21 and the oil blocking strips three 31 from the gap between the oil blocking strips three 31, then flows into the position between the oil blocking strips one 11 and the oil blocking strips two 21 from the gap between the oil blocking strips two 21, and finally flows out from the gap between the oil blocking strips one 11. In Figure 5 the direction, A is the lower surface of the oil blocking strips three 31, B is the lower surface of the oil blocking strips two 21, C is the upper surface of the oil blocking strips three 31, D is the lower surface of the oil blocking strips one 11, and E is the upper surface of the oil blocking strips two 21. When the oil fume flows, it collides with A, B, C, D and E in sequence, that is, the oil fume flow can collide five times.

[0024] The above technical solution adopts the three-layer structure of the inner oil screen 1, the middle oil screen 2 and the outer oil screen 3, so that when filtering the oil fume, the oil fume can collide with the filter screen five times, the collision times are more, the oil blocking strips one 11, the oil blocking strips two 21 and the oil blocking strips three 31 are arranged side by side, so there is no cleaning dead angle when disassembling and cleaning, which is more convenient.

[0025] With reference to the drawings accompanying the specification Figure 5 , the two side edges of the oil blocking strips three 31 are provided with edge edges four 311 protruding to the side of the oil blocking strips two 21, and the two side edges of the oil blocking strips two 21 are provided with edge edges three 212 protruding to the side of the oil blocking strips three 31.

[0026] Further, the two side edges of the oil blocking strips one 11 are provided with edge edges one 111 protruding to the side of the oil blocking strips two 21, and the two side edges of the oil blocking strips two 21 are provided with edge edges two 211 protruding to the side of the oil blocking strips one 11.

[0027] It should be noted that the setting of the edge two 211 and the edge three 212 makes the cross section of the oil baffle two 21 form a H-shaped structure, and through the setting of the edge four 311 and the edge three 212, the oil fume flowing out from the gap between the oil baffle three 31 can be guided to directly collide with C. Similarly, through the setting of the edge one 111 and the edge two 211, the oil fume flowing out from the gap between the oil baffle two 21 can be guided to directly collide with E.

[0028] Referring to the description attached Figures 1-5 The bottom of the outer oil net 3 is provided with a positioning groove 302 with an upward opening, and the bottom of the middle oil net 2 is provided with an insertion block 201. When the middle oil net 2 and the outer oil net 3 are installed, the insertion block 201 is inserted into the positioning groove 302.

[0029] Further, the upper end of the middle oil net 2 is provided with a collision bead one 4, and the upper end of the outer oil net 3 is provided with a positioning hole two 301. When the middle oil net 2 and the outer oil net 3 are installed, the collision bead one 4 is clamped into the positioning hole two 301 from the bottom of the positioning hole two 301.

[0030] Further, the bottom of the outer oil net 3 is provided with a positioning hole 303, and the bottom of the inner oil net 1 is provided with a positioning plate 102. When the inner oil net 1 and the outer oil net 3 are installed, the positioning hole 303 is inserted into the positioning plate 102.

[0031] Further, the upper end of the outer oil net 3 is provided with a collision bead two 5, and the upper end of the inner oil net 1 is provided with a positioning hole one 101. When the inner oil net 1 and the outer oil net 3 are installed, the collision bead two 5 is clamped into the positioning hole one 101 from the bottom of the positioning hole one 101.

[0032] It should be noted that when the inner oil net 1, the middle oil net 2 and the outer oil net 3 are installed, first, the middle oil net 2 and the outer oil net 3 are taken, the insertion block 201 is inserted into the inside of the positioning groove 302 for positioning, then the upper end of the middle oil net 2 is pushed towards the outer oil net 3, so that the collision bead one 4 is clamped into the positioning hole two 301, that is, the installation of the middle oil net 2 and the outer oil net 3 is completed. Then the outer oil net 3 and the inner oil net 1 are installed together, specifically, one side of the middle oil net 2 faces the inner oil net 1, then the positioning hole 303 is inserted into the positioning plate 102 for positioning, and then the upper end of the outer oil net 3 is pushed towards the inner oil net 1, so that the collision bead two 5 is clamped into the positioning hole one 101, that is, the installation of the inner oil net 1 and the outer oil net 3 is completed. In this way, the installation of the inner oil net 1, the middle oil net 2 and the outer oil net 3 is completed. When used, the filter net is installed on the range hood, specifically, the inner oil net 1 is installed on the range hood.

[0033] In the above technical solution, when the middle oil net 2 and the outer oil net 3 and the inner oil net 1 and the middle oil net 2 are installed, the bottom is clamped and positioned first, and the upper end is positioned by the collision bead, so that the installation and disassembly are more convenient.

[0034] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
