Row and stopping, that is to say, that we can open aeration device 4 to realize the introducing of clean air in the case where not opening a window, reach
The purpose taken a breath to room ventilation avoids windowing ventilation and brings the pellets such as dust, pollen into interior to cause room
The generation of the phenomenon that interior air pollution.The pellets such as dust, pollen and toxic and harmful gas etc. due to mankind's activity or
Natural process causes Cucumber to cause air pollution.In the prior art, it when air being guided to interior from outdoor, needs in wall
Upper punching, or draw hole on window and then guide to interior using air hose, still, if the trepanning on building masonry wall, meeting
Building intensity is reduced, fabric structure is destroyed；If punched on glass, since current window-glass is mostly the double-deck glass
Glass will discharge vacuum once scratching glass, lose original heat insulating effect, and some glass trepannings can cause entire glass
Glass is broken, and certain influence is also resulted in the beauty of whole building.Not trepanning, and blower unit can not be installed.This practicality
The window of novel offer can remove on skin or window-glass trepanning to install aeration device 4, can not destroy original
Aeration device 4, particularly suitable family renovated rear later stage can be used to want to pacify again for replacement window on the basis of having Building Design
Fill the user of aeration device 4, the utility model is simple in structure, it is easy to disassemble, can install at any time as needed, dismantle at any time.
Specifically, as shown in Figure 3 and Figure 4, the first sash 21 includes the first sash frame 211 and transparent component 212, thoroughly
Bright component 212 can be paper, cloth, silk or the glass material that light can penetrate, it is contemplated that heat-insulating property and light transmission condition, generally
Material of the glass as transparent component 212 is all used, 4 installing port of aeration device, transparent component are equipped in the first sash frame 211
212 are installed in 2 frame of sash and are fixedly connected with 2 frame of sash, aeration device 4 be located on 4 installing port of aeration device and with
First sash frame 211 is connected, and transparent component 212 abuts against or is connected with aeration device 4.Usual window frame 1 is rectangle
Or square, 2 frame of sash are rectangle, aeration device 4 be installed in the first sash frame 211 and at least with the first window sash frame
Two vertical frames that frame 211 is oppositely arranged are connected, between aeration device 4 and the first sash frame 211, transparent component 212
It is preferable to be seamlessly connected and sealing between the first sash frame 211 and between transparent component 212 and aeration device 4, wherein
Aeration device 4 can be mounted on top, middle part or the lower part of the first sash frame 211.
Preferably embodiment, the second sash 22 can be casement window, or sliding window is opened flat with present
Window is as sliding sash structure, and the utility model is by taking sliding window as an example, as shown in Figure 1, the second sash 22 is sliding window, the second window
Fan 22 includes that interior sash 221 and outer leaf 222 are called interior window when interior sash 221 and the coincidence of outer leaf 222 close to indoor
Fan 221, another fan are outer leaf 222, interior sash 221 and outer leaf 222 is slidably connected respectively with window frame 1 so that interior sash 221
Opposite sliding can occur with outer leaf 222, wherein window frame 1 is sequentially connected end to end by left frame 11, upper ledge 12, right frame 13 and lower frame 14
Form, open up fluted in lower frame 14, be equipped with slideway in groove, slideway includes inner slide and external slideway, the first sash 21 with it is interior
Slideway/external slideway is fixedly connected or is slidably connected so that the first sash 21 can open or close, the second sash 22 and the first sash
When 21 closing, the second sash 22 and the first sash 21 can close air-flow port 3, naturally it is also possible to and it is hinged with the side of window frame 1, it is interior
Sash 221 is slidably connected and can be slided along inner slide level with inner slide, and outer leaf 222 is slidably connected with the external slideway and energy
It is slided along the external slideway level.Certainly, if the second sash 22 is casement window, the second sash 22 can be with window frame 1
Side (such as upper ledge 12 or lower frame 14) is hinged to open and close.
In view of in the prior art can only lock the sliding window in fully closed position, window is being opened into a fixed width
When spending, due to that can change the width of window opening by sash in push-and-pull 221 or outer interior sash 221, there are prodigious peaces
Full hidden danger, for example, especially in the case that no screen window or the openable robber of screen window may from getting in outside window and
Children climb to outside window and accident occur.But some people due to when the health demand of room ventilation is liked and open the window, such as
Where guarantee ventilation under the premise of, as much as possible ensure the person and property safely become urgent problem to be solved.
Preferably embodiment, the window provided by the utility model with fresh air function further include limiting device 5,
As shown in figure 5, the slide window lock namely described in us, there are locking and unlock two states, limiting devices for limiting device 5
5 be in lockup state when, limiting device 5 be fixed between outer leaf 222 and the lower frame 14 of window frame 1 so that outer leaf 222 fix
And the relative displacement in capable of controlling between sash 221 and outer leaf 222, when limiting device 5 is in the unlocked state, limiting device 5
Gap periphery and interior sash 221 and outer leaf 222 between outer leaf 222 and the side wall 6 of groove can be slided on slideway
It is dynamic.Limiting device 5 includes shell 51, screw rod 52, connector 53, fixed stop 54, active block stop 55 and key 56, in shell 51
It is provided with screw rod 52, fixed stop 54 is fixedly connected with shell 51, and keyhole 57 is provided on shell 51, and key 56 can be inserted into key
In keyhole 57, rotation key 56 can make key 56 that screw rod 52 be driven to rotate, and connector 53 is sheathed on screw rod 52 and 52 turns of screw rod
Kinetic energy is subjected to displacement that (screw rod 52 in the utility model is suitable with connector 53 along the axis direction of screw rod 52 with follower link 53
In lead screw transmission), screw rod 52 is connected by connector 53 with active block stop 55 and connector 53 can drive active blade to move.
In use, determining the open maximum width of window first, then screw rod 52 is driven to adjust active block stop 55 by key 56
The distance between fixed stop 54 so that active block stop 55 and fixed stop 54 can be put into outer leaf 222 and lower frame 14 simultaneously
On groove side wall 6 between gap in, the side wall 6 of groove belongs to a part for lower frame 14, it should be noted that living at this time
Dynamic the distance between block 55 and fixed stop 54 are less than on outer leaf 222 towards close indoor on indoor side and lower frame 14
Vertical groove side wall 6 between gap；It is inserted into keyhole 57 with key 56 after being put into and rotates key 56, drive screw rod
52 make active block stop 55 resist the side of the groove on lower frame 14 to adjust the distance between active block stop 55 and fixed stop 54
Wall 6, until key 56 twist it is motionless indicate that the limiting device 5 has installed at this time, outer leaf 222 has been lockable, and cannot be slided,
It is slided in the moving area that interior sash 221 can only be between window frame 1 and limiting device 5, the width of windowing can be controlled, prevented
Children climb out of outside window, safer, when window is in the completely closed state, the limiting device 5 can also be used, in addition existing
Sliding window also has locking device when being in fully closed position, plays the role of dual locking, safer.
