Description
Technical field
The utility model patent is related to a kind of blast cap, and particularly one kind is without airduct VMC exterior wall air port blast cap.
Background technology
VMC is the system for providing fresh air for the indoor environment of relative closure, mainly by air inlet, air-supply
Mouth and air outlet composition, air inlet are located at exterior wall and are located in the region of the ceiling void, and air outlet is installed on furred ceiling, and air outlet is set
On exterior wall below room furred ceiling.This VMC forms fresh air air intake passage using the ceiling void, without setting wind
Road pipeline, its resource consumption is few, and installation workload is few, low cost, reduced investment, has wide application prospect.But this germline
The requirement united to air inlet and air outlet is of a relatively high, and the air outlet and air inlet structure and function of prior art are simple, it is difficult to
Meet that air cleaning and purification require.For this reason, it may be necessary to it is improved.
The content of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, there is provided a kind of blast cap, the blast cap pass through sphere knot
Structure and downward opening air inlet, it can effectively prevent from entering on rainwater or blast cap and accumulate debris；By shutter and protection network with
Effectively prevent other meiofaunas such as insect or mouse from entering, it might even be possible to prevent granule foreign from entering VMC, its structure
Simply, dependable performance, cost are low.
To achieve the above object, the utility model adopts the following technical scheme that.
A kind of blast cap, including mounting disc and rainhat, the rainhat structure spherical in shape, the air intake mouth down on rainhat
And deviate the centre of sphere；The inducer of the mounting disc is formed with shutter, and shutter rear is formed with protection network.
Using the utility model of preceding solution, wind path passage is formed using the reserving hole on wall, passes through ball
Face structure and downward opening air inlet, it can effectively prevent from entering on rainwater or blast cap and accumulate debris；Pass through shutter and protection
Net is effectively to prevent other meiofaunas such as insect or mouse from entering, it might even be possible to prevent granule foreign from entering VMC, its
Simple in construction, dependable performance, cost are low.
Preferably, the shutter is integrally formed in the mounting disc by punching press；The protection network by welding or
Threaded fastener is fixedly connected in the mounting disc.Further ensure that simple in construction, easy to make；Obviously, protection network can be adopted
With sandwich construction, the mesh mesh number of each layer can also differ, preferably gradual by the order in air intake direction, the mesh mesh number of each layer
Increase, gradually to strengthen the separation purifying effect of air.
It is further preferred that the protection network rear is provided with blower fan.To form the independent air intake unit of drive, beneficial to list
Solely control, has reached the energy saver mode of default.
Preferably, the blower fan rear is provided with anion emission unit.It is further net to be carried out using anion to air
Change.
Wherein, blower fan and anion emission unit are set preferably by air duct, and air duct is fixed in mounting disc, and is installed in
In the hole of wall；Blast cap can be worn swell fixture by the multiple mounting holes being distributed thereon and be fixed on the wall, or pass through wind
Elastic card claw on cylinder is fixed with wall hole formation elastic engaging.
The beneficial effects of the utility model are that simple in construction, dependable performance, dedusting and purifying air effect is good, can fully be expired
The air intake requirement of sufficient VMC.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model Fig. 1 upward view.
Fig. 3 is A-A sectional views in the utility model Fig. 2.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not therefore limited in institute
Among the scope of embodiments stated.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of blast cap, including mounting disc 1 and rainhat 2, multiple installations are distributed with mounting disc 1
Hole 1c；2 structure spherical in shape of rainhat, air intake mouth down on rainhat 2 simultaneously deviate the centre of sphere；The import of the mounting disc 2
Section is stated shutter 2a and is integrally formed in by punching press in the mounting disc 2 formed with shutter 1a；Shutter 1a rears formed with
Protection network 1b；Protection network 2b is fixedly connected in the mounting disc 2 by welding or threaded fastener.
Wherein, the rear of blower fan 3 is provided with anion emission unit 4；Mounting disc 1 is provided with air duct 5, blower fan 3 and anion hair
Unit 4 is penetrated to be located in air duct 5, air duct 5 is provided with the elastic card claw 5a of three circumference uniform distributions, elastic card claw 5a from barrel it is circumferential to
Outer extension, and it is integral with tunnel wall type, receiving space when elastic card claw 5a is pushed back, three elastic card claws are additionally provided with barrel
5a simultaneously towards extending counterclockwise or clockwise, and when rotating air duct 5 by direction initialization to facilitate, three elastic card claw 5a are equal
Pushed back.
In the present embodiment, the elastic card claw 5a on mounting hole 1c and air duct 5 in mounting disc 1 may be selected one of them and set
Put；In addition, elastic card claw 5a quantity can also be 2,4 etc..
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks
