Abstract
The utility model provides a ventilation cap, which comprises an arc-shaped top cover (10) and a support frame (20) which is connected with the arc-shaped top cover (10) and positioned below the arc-shaped top cover (10). The ventilation cap solves the problems of poor wind and sand resistance, rainwater resistance and poor ventilation effect of a ventilation pipe.
Description
Technical field
The utility model relates to technical field of buildings, in particular to a kind of ventilator.
Background technology
For a long time, the general pipeline of ventilation system pipeline that is usually used in civil buildings toilet (comprising the kitchen) and industrial building with straight-through outdoor deck.
As shown in Figure 1, the air draft sketch map of ventilation pipe on roof, owing to there is not the setting of ventilator, ventilation duct can't stop that wind, sand, rain and snow get into ventilation duct and causes normally air draft of ventilation duct, and can produce the infringement of ventilating system.
As shown in Figure 2, the ventilation duct on roof adopts the elbow shape, can solve the adverse effect that dust storm sleet causes roof ventilation simply.But through measuring, the ventilation duct of elbow shape has certain resistance at air outlet, be unfavorable for ventilating, and the maintenance cost of ventilation duct itself is higher.
The utility model content
The utility model aims to provide a kind of ventilator, to solve the problem of the anti-dust storm of ventilation duct, anti-rainwater, ventilation effect difference in the prior art.
To achieve these goals, an aspect according to the utility model provides a kind of ventilator, comprising: arc top cover and bracing frame; Bracing frame is connected with the arc top cover, and is positioned at the below of arc top cover.
Further, the arc top cover has along lower surface to first connector that extends below, and the arc top cover is connected with bracing frame through first connector.
Further, the ventilator of the utility model also comprises: the circular base and second connector; Its center of circular base has the through hole of dodging; First end of second connector is connected with the upper surface of circular base, and second end and first connector of second connector removably connect.
Further, first connector and second connector are spirally connected.
Further, the material of ventilator is the wire drawing stainless steel.
Further, second connector is a plurality of, and a plurality of second connectors circumferentially evenly distribute along circular base.
Further, the projection on the ground of arc top cover is greater than bracing frame projection on the ground.
Ventilator according to the technical scheme of the utility model comprises: arc top cover and bracing frame; Bracing frame is connected with the arc top cover, and is positioned at the below of arc top cover.Ventilator is arranged on corresponding ventilating opening place; Its shape of arc top cover can more effectively be kept out dust storm and stopped that rainwater gets into ventilating opening; The lower surface of arc top cover be shaped as circular arc, the wind of discharge spread to all sides through dome, thereby improves the efficient of ventilation.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the smoke evacuation view of the embodiment of ventilation duct in the prior art;
Fig. 2 shows the smoke evacuation view of the embodiment of 180 ° of elbow ventilation ducts in the prior art;
Fig. 3 shows the structural representation of embodiment of the ventilator of the utility model;
Fig. 4 shows the smoke evacuation view of the ventilator of Fig. 3; And
Fig. 5 shows the elevational schematic view of the ventilator of Fig. 3.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Like Fig. 3 and shown in Figure 4, the ventilator of present embodiment comprises: arc top cover 10 and bracing frame 20; Bracing frame is connected with arc top cover 10, and is positioned at the below of arc top cover 10.
Ventilator is arranged on corresponding ventilating opening place; The shape of arched top cover upper surface can more effectively be kept out dust storm and stopped that rainwater gets into ventilating opening; The lower surface of arc top cover be shaped as circular arc, the wind of discharge through dome to the side diffusion of dome week, thereby improve the efficient of ventilating.
Like Fig. 4 and shown in Figure 5, arc top cover 10 has along lower surface to first connector 13 that extends below, and arc top cover 10 is connected with bracing frame 20 through first connector 13.Bracing frame 20 comprises: the circular base 21 and second connector 23; Circular base 21 its centers have the through hole of dodging; First end of second connector 23 is connected with the upper surface of circular base 21; Second end of second connector 23 and first connector 13 removably connect, be spirally connected between first connector 13 of ventilator and second connector 23 in the present embodiment, and also can be that other removably connect.Like this, make the installation and removal of ventilator convenient.
Preferably, second connector 23 is a plurality of, and a plurality of second connectors 23 circumferentially evenly distribute along circular base 21.Be provided with the structural strength that helps strengthen ventilator like this.Preferably, the material of ventilator is the wire drawing stainless steel.The wire drawing stainless steel material can anticorrosion effectively prevent the ventilator rustization, has prolonged the service life of ventilator.Preferably, arc top cover 10 projection on the ground is greater than bracing frame 20 projection on the ground.Make the smoke discharging effect of ventilation duct better like this.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
