Air inlet is communicated with room air；Cover board is additionally provided in the air outlet structure ontology；The cover board for block fresh air into
Air port or old wind air inlet；The cover board realizes rotation, outlet air by the motor driven being mounted on air outlet structure ontology
Controller is also equipped on mouth structure ontology；The controller is used to control the positive and negative rotation of motor；The air outlet structure ontology
Inside it is additionally provided with strainer.Motor rotation is controlled by controller, drives cover board rotation, blocks the fresh air of bottom when cover board turns to
When air inlet, the old wind air inlet at the back side is opened, and at this time from outdoor introducing fresh air, realizes outer circulation；It is blocked when cover board turns to
When the old wind air inlet at the back side, the fresh air air inlet of bottom is opened, and indoor air enters through old wind air inlet, passes through strainer pair
Indoor air is filtered, and realizes interior circulation.
The cover board is made of two block baffles and shaft, the two block baffles position with fresh air air inlet and old wind air inlet respectively
Corresponding, two block baffles composition " V " font is set, less than 90 degree, baffle is connected to the motor the angle between baffle by shaft
It connects.Since two block baffles are V-shaped, and the angle between baffle is less than 90 degree, when one of baffle and fresh air are entered the wind
When mouth contact, then there is a tilt angle between old wind air inlet in another baffle, opens old wind air inlet, thus, fresh air
Air inlet and old wind air inlet have one to be in opening, another state in closing always.
On the cover board with fresh air air inlet or the position that contacts of old wind air inlet be provided with sealant.Sealant is deposited
Baffle is being increased to the sealing effect of fresh air air inlet and old wind air inlet, is realizing the smooth switching between inner-outer circulation.
The sealant is rubber layer.The effect of sealing was not only ensure that as sealant using rubber material, but also can be right
Baffle plays the effect of buffering with the contact of fresh air air inlet and old wind air inlet.
The strainer uses HEPA filter screen set group.
The beneficial effects of the utility model are as follows:
1. a kind of fresh air system inner-outer circulation conversion equipment described in the utility model, the utility model passes through controller control
Motor rotation processed, drives cover board rotation, when cover board turns to the fresh air air inlet for blocking bottom, the old wind air inlet at the back side is beaten
It opens, at this time from outdoor introducing fresh air, realizes outer circulation；When cover board turns to the old wind air inlet for blocking the back side, bottom it is new
Wind air inlet is opened, and indoor air enters through old wind air inlet, is filtered by strainer to indoor air, followed in realization
Ring, being engaged in keeps conversion device structure simple and can satisfy requirement.
2. a kind of fresh air system inner-outer circulation conversion equipment described in the utility model, the utility model is by using rubber
Material not only ensure that the effect of sealing as sealant, but also can rise to baffle with the contact of fresh air air inlet and old wind air inlet
To the effect of buffering.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the main view of the utility model；
In figure: air outlet structure ontology 1, cover board 2.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines specific embodiment, and the utility model is further described.
As shown in Figure 1, a kind of fresh air system inner-outer circulation conversion equipment, including air outlet structure ontology 1, the air outlet
Going out for old wind air inlet and top is arranged in the back side of the bottom setting fresh air air inlet and outlet structural body 1 of structural body 1
Air port, fresh air air inlet are communicated with outdoor, and old wind air inlet is communicated with room air；It is also set in the air outlet structure ontology 1
It is equipped with cover board 2；The cover board 2 for block fresh air air inlet or old wind air inlet；The cover board 2 is by being mounted on air outlet
Motor driven in structural body 1 realizes rotation, is also equipped with controller on air outlet structure ontology 1；The controller is used for
