Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

The first embodiment of the present invention relates to a hair dryer body, as shown in fig. 1 and 2, comprising an outer wall 1, an inner wall 2 and a plurality of grills 3 disposed between the outer wall 1 and the inner wall 2. Wherein, inner wall 2 sets up in outer wall 1 to with outer wall 1 coaxial fixed, and separate each other and form an annular air-out district between inner wall 2 and the outer wall 1, and the end in this annular air-out district is the air outlet 5 of air current. Each grid 3 all sets up in air outlet 5 department, and the width of each grid 3 and outer wall 1 and inner wall 2 junction increases along the air-out direction in the annular air-out district gradually, and further, each grid 3 all is greater than or equal to 2 millimeters along the terminal width of air-out direction. And when the width of the tail end of each grid 3 along the air outlet direction is less than 2 millimeters, because the size of the grid 3 is too small, the airflow flowing to the middle area of the air outlet through the wall attachment effect is fused into a stable annular vortex outside the air outlet, and then noise is generated, so that the hair dryer has higher noise during working.

Through the above, it can be easily found that, because the body of the hair dryer comprises an inner wall 2, an outer wall 1 and a plurality of grilles 3, wherein, the inner wall 2 is arranged in the outer wall 1 and is coaxially fixed with the outer wall 1, and an annular air-out area is formed between the inner wall 2 and the outer wall 1, meanwhile, the inner wall 2 and the outer wall 1 form an air outlet 5 at the tail end of the annular air-out area, each grille 3 is arranged at the air outlet 5, meanwhile, the width of the joint of each grille 3 and the outer wall 1 and the inner wall 2 is gradually increased along the air-out direction in the annular air-out area, and the width of each grille 3 at the tail end of the air-out direction is more. Specifically speaking, because the width of each grid 3 is crescent along the air-out direction of annular air-out district, therefore can carry out the water conservancy diversion to hair-dryer air current, and the width of each grid 3 along the end of air-out direction all is more than or equal to 2 millimeters, and the air current of flowing to air outlet middle zone by the coanda effect is separated, can not fuse into the annular vortex of a steady state, and then eliminate the noise that is produced by steady state torrent, and then reduce the noise of hair-dryer during operation, promote user experience. The coanda effect is a coanda effect, and specifically, a fluid has a tendency to flow along a convex object surface instead of an original flow direction, and when surface friction exists between the fluid and the object surface through which the fluid flows, the fluid flows along the object surface.
