Abstract
The utility model discloses a kind of door and window ventilator, comprise shell, bridge insulation thermal resistance connection strap, air door, acoustical cotton, indoor square, described bridge insulation thermal resistance connection strap is arranged in the middle of outer, the interior both sides of described shell, it is characterized in that: also comprise the first screen pack, the second screen pack.The utility model can play the effect of the outer mosquito of effective isolation ward, dust, noise reduction.
Description
Technical field
The utility model belongs to ventilation unit, is specifically related to a kind of building doors and windows ventilator.
Background technology
Generally, building, as needed ventilation, just need open the door and window of building, opens the external door and window of building and brings the problems such as outdoor noise, dust, safe antitheft.
In order to solve the problem, gone into circulation door and window ventilator on the market, these door and window ventilator are generally arranged on the top edge of door and window, and for connection door window frame body and door and window body, ventilator is generally made up of shell, bridge cut-off, air door (air channel guide plate) and other sound-absorbing material individual.
There is following shortcoming in existing door and window ventilator: 1, does not have airstrainer, enters that indoor air quality is poor, mosquito, dust easily enter indoor; 2, indoor square can not disassembly, cleaning; 3, acoustical cotton setting position is improper, and shape makes air channel formation right angle transposition, and wind loss is large, sound insulation and noise reduction weak effect; Air door is generally hard material, can make formation gap, air channel, can be formed " birdie " under high wind weather.
Utility model content
For above-mentioned existing issue, problem to be solved in the utility model is to provide a kind of door and window ventilator, solves existing Problems existing.
For achieving the above object, the utility model adopts following technical scheme:
Door and window ventilator, comprise shell, bridge insulation thermal resistance connection strap, air door, acoustical cotton, indoor square, described bridge insulation thermal resistance connection strap is arranged at outside described shell, in the middle of interior both sides, it is characterized in that: also comprise the first screen pack, second screen pack, described door and window ventilator sets gradually order outdoor for described first screen pack to indoor direction along air channel, described air door, described acoustical cotton, described second screen pack, described indoor square, described acoustical cotton is arranged on described air door balance staff end near indoor end side, the one side that described acoustical cotton contact enters wind is inner concave arc surface, because acoustical cotton is arranged on the balance staff end of air door, enter after wind is guided by air door and directly contact acoustical cotton, the very first time plays noise reduction, the one side that the contact of acoustical cotton contact simultaneously enters wind is arranged to cambered surface, eliminate right angle, air channel, reduce wind loss.First screen pack may be used for isolation big dust particle, winged insect; Second screen pack can molecule in air-isolation.
Particularly, described air door is PVC soft or hard adhesive tape, eliminates the gap with shell, stop birdie when air door is closed.
Particularly, described first screen pack is stainless steel filter screen.
Particularly, described second screen pack is active carbon or photo-catalytic filtering screen.
More preferably, described indoor square vertically has downwards and extends to form handle, cleaning for convenience detach.
The beneficial effects of the utility model are:
1, air door adopts soft-hard coextrusion, air-tightness when effectively ensureing in off position;
2, Duct design rounding, effectively organizes the flow direction of wind orderly, does not produce disorder, reduce the loss of air quantity simultaneously;
3, air channel adopts acoustical cotton, can attenuate external noise, can effectively prevent " birdie " to produce simultaneously.
4, overall structure adopts twice filter screen filtration, the preliminary Chalk-dust filtering of primary efficient filter screen, particle; Secondary filter net environmentally difference can select different screen pack (active carbon, photocatalyst etc.).
5, leave handle space between indoor square lower end and agent structure, be convenient to the dismounting of square, make the cleaning of screen pack and change convenient and easy.
Accompanying drawing explanation
Fig. 1 is the end face structure schematic diagram of door and window ventilator of the present utility model.
Wherein, 1, bridge insulation thermal resistance connection strap; 2, acoustical cotton; 3, air door; 4, the first screen pack; 5, the second screen pack; 6, indoor square.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, other embodiments that those skilled in the art obtain under the prerequisite not making creative work, all belong to the protection domain of this patent.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, door and window ventilator comprises shell (without mark on figure), bridge insulation thermal resistance connection strap 1, air door 3, acoustical cotton 2, indoor square 6, described bridge insulation thermal resistance connects 1 and is arranged at outside described shell, in the middle of interior both sides, it is characterized in that: also comprise the first screen pack 4, second screen pack 5, described door and window ventilator sets gradually order outdoor for described first screen pack 4 to indoor direction along air channel, described air door 3, described acoustical cotton 2, described second screen pack 5, described indoor square 6, described acoustical cotton 2 is arranged on described air door 3 balance staff end near indoor end side, the one side that described acoustical cotton 2 contact enters wind is inner concave arc surface, because acoustical cotton 2 is arranged on the balance staff end of air door 3, enter wind and guide rear direct contact acoustical cotton 2 by air door 3, the very first time plays noise reduction, the one side that acoustical cotton 2 contact simultaneously enters wind is arranged to cambered surface, eliminate right angle, air channel, reduce wind loss.First screen pack 4 may be used for isolation big dust particle, winged insect; Second screen pack 5 can molecule in air-isolation.
Particularly, described air door 3 is PVC soft or hard adhesive tape, eliminates the gap with shell, stop birdie when air door 3 is closed.
Particularly, described first screen pack 4 is stainless steel filter screen.
Particularly, described second screen pack 5 is active carbon or photo-catalytic filtering screen.
More preferably, described indoor square 6 vertically has downwards and extends to form handle, cleaning for convenience detach.
To one skilled in the art; can according to technical scheme described above and design; make other various corresponding change and deformation, and all these change and deformation, change all should belong within the protection domain of the utility model claim.
