Abstract
The utility model provides an electric tool detachable air inlet dust-proof mesh structure. An opening on the rear portion of a machine outer shell, and a groove on the inner side of the large grid air inlet are used for fixing a dust-proof mesh of a small grid structure, a buckle arranged on one side of the mesh can buckle the opening on the rear portion of the machine outer shell, and the dust-proof mesh is stably arranged on the inner side of the large grid air inlet. Air inlet of a small gird air inlet is achieved, wool fiber type dust is effectively prevented from entering, the top of the dust-proof mesh is provided with a protrusion, the dust-proof mesh can be separated from the buckle on the opening of the rear portion of the machine outer shell by wrenching the protrusion, the dust-proof mesh is taken out from the opening of the rear portion of the machine outer shell, air inlet of the machine large grid air inlet is achieved, requirements of large air quantity of a machine are met, and the machine is protected effectively.
Description
Affiliated technical field
The utility model relates to a kind of dismountable air inlet Air Filter chip architecture of electric tool.
Technical field
The utility model relates to a kind of dismountable air inlet Air Filter chip architecture of electric tool, relates in particular to prevent that the fine class dust of hair from entering machine, also dismountable to guarantee the large air intake demand of machine under other operating modes.
Background technology
The air inlet of existing electric tool such as Fig. 1, machine is by 1 mouthful of air intake of air intake of large grid, and all kinds of dust can enter machine intimate easily in this case, and then machine is caused damage, particularly the fine class dust of hair can be piled up at machine intimate, stops up heat dissipation channel, causes machine overheated impaired.
Summary of the invention
Defects for existing electric tool air inlet existence, the utility model provides a kind of novel detachable net chip architecture, this structure is to add dismountable net sheet mechanism in the air inlet inside of large grid, add the networking sheet under the operating mode of the fine class dust of crinosity, allow machine by little grid air intake, effectively stop the fine class dust of hair to enter machine, thus the protection machine; In the situation that the large intake of machinery requirement is removed the net sheet, allow machine by large grid air intake, to guarantee the intake of machine, prevent that machine is overheated, thus the protection machine.
The technical scheme that its technical problem that solves the utility model adopts is: there is opening at the machine casing rear portion, be provided with groove in large grid air inlet inboard, opening by the machine casing oral area is along this groove, the Air Filter sheet of little grid can be close to large grid air inlet inboard and put into, Air Filter sheet one side has buckle to fasten machine casing, and with fixing Air Filter sheet, projection is arranged at Air Filter sheet top, in order to pull open the buckle that fastens machine casing on the Air Filter sheet, make the Air Filter sheet can be without the instrument dismounting.
The beneficial effects of the utility model are, by packing under different operating modes and removing the Air Filter sheet of little grid, can realize that the big or small grid of machine air inlet switches; The Air Filter sheet is contained in machine intimate, can prevent that in the machine use, the Air Filter sheet comes off and damages.The Air Filter sheet of packing into the time can prevent effectively that the fine class dust of hair from entering, and can guarantee the large intake of machine, thereby effectively protect machine when removing the Air Filter sheet.
Description of drawings
Fig. 1 is existing electric tool air inlet schematic diagram.
Fig. 2 is the detachable air inlet Air Filter sheet of the present utility model schematic diagram of packing into.
Fig. 3 is that detachable air inlet Air Filter sheet of the present utility model is removed schematic diagram.
The specific embodiment
Be described further below in conjunction with the accompanying drawing specific embodiment of the present utility model.
As shown in Figure 2, detachable Air Filter chip architecture of the present utility model, comprise the large grid air inlet 3 of opening 2, machine at machine casing 1 rear portion and the groove 4 of air inlet inboard, Air Filter sheet 5 has little lattice structure 6, the buckle 7 of Air Filter sheet one side makes the stable machine casing 1 of packing into of Air Filter sheet 5, realize the little grid air inlet of machine air intake, effectively stop the fine class dust of hair to enter.As shown in Figure 3, by pull Air Filter sheet 5 tops projection 8, buckle 7 is thrown off from machine casing rear aperture 2, take out Air Filter sheets 5 from machine casing rear aperture 2, realize the large grid air inlet of machine air intake, guarantee the large intake demand of machine.
Claims (1)
1. the detachable air inlet Air Filter of electric tool chip architecture comprises:
There is opening at the machine casing rear portion, is provided with groove in large grid air inlet inboard;
Opening by the machine casing oral area is along this groove, and the Air Filter sheet of little grid can be close to large grid air inlet inboard and put into, and Air Filter sheet one side has buckle to fasten machine casing, with fixing Air Filter sheet;
