Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

Example 1

As shown in fig. 1-4, a high-protection ventilation device comprises a cabinet body shell 1, a housing 2, a mesh plate 3, dustproof cotton 4 and a grid plate 5;

the cabinet body shell 1 is provided with a rectangular hole 101 for ventilation, the inner side of the rectangular hole 101 is sealed by a housing 2, the housing 2 is welded and fixed on the inner side of the cabinet body shell 1, and an air channel is formed between the housing 2 and the cabinet body shell 1;

the upper end surface of the housing 2 is provided with an inside and outside ventilated screen plate 3, and dustproof cotton 4 is arranged above the screen plate 3;

grid plate 5 sets up inside housing 2, the separation is between the wind channel of long square hole 101 and otter board 3, grid plate 5 forms the V-arrangement board along the axis bending type, the both sides of V-arrangement board are all fixed on 1 inner wall of cabinet body shell, the both sides of V-arrangement board are rolled over outwards and are formed fixed sideboard, fixed sideboard passes through fix with rivet on 1 inner wall of cabinet body shell, the bellied axis one side of V-arrangement board and 2 inner wall in close contact with of housing, the V-arrangement board is separated into upper plate 501 and lower floor's board 502 by the axis, a plurality of upper strata waist hole 503 have been seted up on the upper plate 501, a plurality of lower floor's waist hole 504 have been seted up on the lower floor's board 502, upper strata waist hole 503 and lower floor's waist hole 504 dislocation set. The upper plate 501 and the lower plate 502 are both obliquely arranged, so that water drops can flow downwards conveniently, and water accumulation cannot be formed.

As shown in fig. 1 and 3, the upper layer waist hole 503 is disposed at the interval between the lower layer waist holes 504 corresponding to the insertion slot, and the two holes are staggered to keep the upper layer plate 501 blocking the outlet of the lower layer waist hole 504 all the time, after the grid plate 5 is installed, the upper layer waist hole 503 and the lower layer waist hole 504 are not in the same vertical line, so that water drops can be prevented from splashing upwards better. In the sectional structure view of fig. 1, only the lower layer waist hole 504 is present, and the upper layer waist hole 503 is not present.

The working principle is as follows:

(1) the ventilation device has better waterproof performance, when water splashes into the cabinet body shell 1 along the rectangular holes 101, only a small part of water penetrates through the lower layer waist holes 504 of the grid plate 5 through reflection and reaches a triangular area formed by the grid plate 5 and the cabinet body shell 1, because the upper layer waist holes 503 and the lower layer waist holes 504 of the grid plate 5 are arranged in a staggered mode, the splashed water is basically blocked by the upper layer plate 501 of the grid plate 5, even if a small amount of liquid drops penetrate through the upper layer waist holes 503 of the grid plate 5, the liquid drops need to be blocked by the screen plate 3 and the dustproof cotton 4, and finally the liquid flows out of the rectangular holes 101 in the bottom of the cabinet body shell 1 under the action of gravity, so that the waterproof grade is obviously improved;

(2) the ventilating device can better prevent solid sundries from entering, can prevent sundries larger than meshes 301 from entering through selecting the sizes of the meshes 301 of the screen plate 3, and additionally adds dustproof cotton 4 on the screen plate 3 to further improve the protection grade.
