Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: in order to enable the shell 1 to be far away from the ground, four corners of the outer bottom of the shell 1 are respectively welded with supporting legs 14, the bottom ends of four groups of supporting legs 14 are respectively designed to be frustum-shaped, the bottoms of the four groups of supporting legs 14 are respectively connected with a first rubber sleeve 15 in a gluing mode, so that the supporting stability of the supporting legs 14 is improved, a handle 18 is welded to the outer top of the shell 1 in order to carry the device conveniently, and a second rubber sleeve 19 is connected to the handle 18 in a gluing mode and used for increasing the grasping friction of the hand;

placing blocks 3 are welded at the inner vertex angles of the shell 1, the vertex angles of the motor body 2 are in contact with the placing blocks 3 but not connected, in order to enhance the clamping tightness of the motor body 2 and the placing blocks 3, elastic rubber pads 16 are glued on the placing blocks 3, an output shaft of the motor body 2 penetrates through the side wall of the shell 1, a fan 5 is fixed on one side of the inner wall of the shell 1 through clamping blocks 4, the inner wall of the shell 1 is obliquely arranged close to one side of the fan 5, heat dissipation holes 6 are formed in the top and the bottom of the shell 1, dust filter nets 7 are embedded in the heat dissipation holes 6, a heat conduction plate 8 is embedded in the side wall of the shell 1, and the;

top and bottom symmetry are provided with fixed subassembly 9 in shell 1, fixed subassembly 9 includes first connecting rod 10, spring 11, second connecting rod 12 and fixed plate 13, first connecting rod 10 one end welds in shell 1 inner wall, second connecting rod 12 one end is passed through spring 11 and is connected with first connecting rod 10, fixed plate 13 welds in second connecting rod 12 one end, fixed plate 13 nevertheless does not connect with motor body 2 contact, the vibration energy that motor body 2 function produced can be absorbed in spring 11's setting, foam-rubber cushion 17 has still been glued on fixed plate 13, make motor body 2 and fixed plate 13 flexonics.
