Preferably, the blade maximum anglec of rotation is 45 °.
The beneficial effects of the utility model embody in the following areas：Row provided by the utility model with sand-proof function
Wind apparatus, effectively it can prevent sand and dust from entering interior by air exhausting device.
Brief description of the drawings
Fig. 1 is the air exhausting device longitudinal sectional view described in the utility model with sand-proof function.
Fig. 2 is shutter schematic diagram described in the utility model.
Fig. 3 is self hang down type blinds principle schematic described in the utility model.
Fig. 4 is separating layer structure schematic diagram described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, square exhaust outlet is offered on wall 110, it is provided by the utility model that there is refrigerating function
Air exhausting device be arranged on exhaust outlet at.
Air exhausting device provided by the utility model with refrigerating function, including along the steam vent of wall 110 from the outside to the core according to
Shutter 120, separating layer 130, screen pack 140, ventilating fan 160 and the motor 170 of secondary arrangement.
Fig. 2, Fig. 3 are referred in the lump, and the shutter 120 is self hang down type shutter, and it includes multiple vertically arranging
Blade 121, be provided with rotating shaft 122 at the upper edge of blade 121, the blade 121 122 is rotated around the shaft, make
The lower edge of the blade 121 is mobile to steam vent outside.It is connected between two blades 121, the bottom pressure of blade 121 above
The top of blade 121 below, makes under nature, and blade 121 is sagging, is arranged vertically, and will be arranged by the blade 121 of whole
The outside in air port seals, and prevents the air outside wall 110 to be flowed into wall 110., can be by air-flow certainly when air exhausting device works
Blow from inside to outside, blade 121 is blown open, the maximum rotation angle of blade 121 is 45 degree, i.e. the from-inner-to-outer of blade 121 forms one
Downward slope, when rainy day air exhausting device works, rainwater is beaten can flow to wall on blade 121 along blade 121
Outside 110, the inner side of wall 110 will not be entered.
Such as Fig. 1, as shown in figure 4, the separating layer 130 is provided with multiple fold-line-shaped airways 131 from top to bottom, pass through institute
Stating airway 131 makes the contact air of separating layer both sides.The separating layer 130 is by multiple S types point vertically arranged
Formed from plate 132, the S types separating plate 132 is sheet metal, the two neighboring interlaced arrangement of S types separating plate 132, i.e. the S of top
The position of the lower end of type separating plate 132 is lower than the position of the following upper end of S types separating plate 132, makes two neighboring S types separating plate
Fold-line-shaped airway 131 is formed between 132.Due to the presence of fold-line-shaped airway 131, when making strong wind occur outside wall, wall
Outer air flows from the outside to the core, when the solid such as grains of sand being mingled with air large particulate matter passes through fold-line-shaped airway 131, meeting
Separated by fold-line-shaped airway 131, large particulate matter is beaten in the side wall of fold-line-shaped airway 131, then in itself weight
Least significant end is slipped to downwards under power effect.
The surface of screen pack 140 is concavo-convex, to increase surface area, so as to strengthen filter effect.
Cross bracket is provided with the inside of exhaust outlet, the housing of motor 170 is fixed on cross bracket, is driven
The output axis connection ventilating fan 160 of dynamic motor 170, the work of motor 170 drive ventilating fan 160 to rotate, make air from wall
110 inner sides flow to the outside of wall 110 through exhaust outlet.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization.It can be applied to various suitable fields of the present utility model completely.For those skilled in the art,
Other modification is easily achieved.Therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
