Description
Technical field
The present invention relates to vented exhaust equipment, a kind of specifically preventing air reverse flow air-valve.
Background technique
No duct type fresh air system is made of new blower and breathing treasured, by air outside new blower clean room and imports interior,
Then foul indoor air is discharged by breathing treasured.General new blower is placed on parlor, and breathing treasured is placed on bedroom.But in breathing treasured
Portion's not air draft constantly, if the wind-force outside room is larger and temperature is lower, such as the north winter, in this way outdoor cold wind can flow backward into
Interior substantially reduces the comfort of people, has noise and reduces clean-up effect.
The existing patented technology of our company, Authorization Notice No. are as follows: CN205717792U, the day for announcing are on November 23rd, 2016,
It discloses a kind of breathing treasured, and silica gel check apron is mounted at the air outlet of shell and is pressed on from the blinds that hangs down, in breathing treasured
When portion's not air draft, silica gel check apron is affixed on from vertical blinds and blinds fixed frame.It can slow down the generation of downdraught phenomenon, but silica gel
Simultaneously imprecision still has wind at the edge of silica gel check apron and pours into also without good fixed structure for the cooperation of check apron and air outlet,
Therefore it cannot accomplish the problem of being fully solved downdraught.
The existing treasured equipment that breathes is a kind of small-sized new wind devices of air interchange type, its integral installation can be connected on wall
The air circulation of two spaces, its structure mainly include being mounted on the air inlet of wall side, are mounted on the wall other side
Body, body is interior to be equipped with suction ventilator, and suction ventilator lower part is equipped with ventilating duct, and ventilating duct is fixedly connected with casing, ventilating duct and air draught
Mouth is connected to, and is additionally provided with filter core, filter disc etc. in body.
Summary of the invention
To solve the problems of the prior art, the present invention provides a kind of wind valve structure that can limit wind direction, effectively
Downdraught is stopped to enter in body.
To achieve the above object of the invention, the technical solution adopted by the present invention is that:
A kind of preventing air reverse flow air-valve, it includes that motor and motor fixing seat, wherein motor fixing seat and casing are affixed one
Body structure；Motor is mounted in motor fixing seat, and motor is in immediately below ventilating duct, and screw rod, screw rod are housed on motor output shaft
It is overlapped with ventilating duct center line；It is additionally provided with wind deflector and shaft, wind deflector center is equipped with screw, and wind deflector is mounted on screw rod,
The board diameter that keeps out the wind is more than or equal to diameter on the downside of ventilating duct.
This programme wind deflector and screw rod are cooperated in the form of screw-nut, motor just becoming a full member wind deflector claim to ventilating duct block lead
Air duct makes to realize radix saposhnikoviae, and baffle shifts to that motor is normal to cross wind when motor reversal.Motor is controlled by master controller, can be had when shutting down
Effect closes wind path, prevents downdraught.
Preferably, wind deflector periphery is equipped with sealing cotton.
Preferably, wind deflector medium design is the slot that can cover motor, and periphery is designed as the flange cooperated with ventilating duct.
Detailed description of the invention
Fig. 1 structure of the invention figure；
Fig. 2 present invention state diagram when breathing precious normal air draft；
Fig. 3 is present invention state diagram in the precious shutdown of breathing.
In figure, motor fixing seat 1, wind deflector 2, screw rod 3, motor 4, ventilating duct 5.
Specific embodiment
Wind valve structure provided by the invention is suitable for breathing treasured or similar devices, can effective closing machine in equipment downtime
Body prevents downdraught.The present invention is illustrated with reference to the accompanying drawing,
As shown in Figure 1-3, a kind of preventing air reverse flow air-valve, it includes motor 4 and motor fixing seat 1, wherein motor fixing seat 1
It is affixed integral structure with casing；Motor 4 is mounted in motor fixing seat 1, and motor 4 is in immediately below ventilating duct 5, and motor 4 is defeated
Screw rod 3 is housed, screw rod 3 is overlapped with 5 center line of ventilating duct on shaft；It is additionally provided with wind deflector 2, wind deflector center is equipped with screw, gear
Aerofoil is mounted on screw rod, and 2 diameter of wind deflector is more than or equal to 5 downside diameter of ventilating duct.
In conjunction with Fig. 2, Fig. 3, the working principle of this air-valve is:
A) affixed screw rod 3 on stepper motor output shaft, screw is equipped among wind deflector 2, and wind deflector 2 and motor output shaft are logical
Cross screw rod, screw is threadedly engaged, the axial rotation forces of motor output shaft are converted to the power that wind deflector moves up and down.
B) when starting breathing is precious, breathing is precious to when outdoor air draft, and wind deflector 2 is as shown in Fig. 2, be in and motor side, wind-guiding
To be open, air is discharged cylinder 5 by ventilating duct.
C) precious when closing breathing, when breathing is precious inoperative, wind deflector 2 is driven by motor 4 and is displaced, and is moved to such as Fig. 3
It is shown, it is close together with ventilating duct 5, closes ventilating duct 5, the air in outside is prevented to flow backward the hair of this phenomenon inwardly
It is raw.
Further, 2 periphery of wind deflector be equipped with sealing cotton, be bonded wind deflector with ventilating duct tighter, can completely every
From air.
Wind deflector medium design of the invention is the slot that can cover motor, and periphery is designed as the flange cooperated with ventilating duct.
When wind deflector is in motor side, centre covers on motor 4 in slot, and wind deflector bottom is adjacent to motor fixing seat 1.Flange can be with
It is whole to be made of sealing cotton.
This wind valve structure the utility model has the advantages that 1) can be completely isolated by air duct in equipment not air draft, thoroughly avoid flowing backward
The generation of wind phenomenon；2) air duct can be fully sealed, and reduce noise；3) total is simply easy to install, and the action of baffle passes through
Motor driven does not need human intervention, easily.
