Description

Indoor air changer

Technical field:

The utility model relates to a kind of ventilation equipment, particularly relates to a kind of indoor air changer that can in good time change room air.

Technical background:

Along with the high speed development of society, make that the construction of various infrastructure is more complete, and building is wherein a kind of, existing building is owing to density height, space are little, so ventilation effect is poor.It is reported: for satisfying consumer's check needs, the raising consumer knows vacation and distinguishes false ability, strengthens manufacturing enterprise's quality responsibility consciousness simultaneously, Suzhou Department of Qulity Supervision has carried out large-scale free detected activity, and announced the final result of free detection, think that nearly four one-tenth resident family's IAQs are defective.Analytical structure draws following reason: 1, finishing reason, and at present the building materials market quality of materials is uneven, and citizen select the improper meeting of material to cause organic volatile etc. to exceed standard; 2, furniture density is bigger, and part is used low-grade half furniture; 3, the airtight time was longer before part resident family was detected; 4, part resident family has just fitted up end or has fitted up, and causes burst size of methanal to exceed standard; 5, owing to moisture, peculiar smell and the dust etc. of the many indoor generations of waste gas, the especially people of body metabolism and the release of each internal organs, these pollution sources are to exist forever, must go its eliminating after door and window is closed.

Based on above report, present room, office etc. are because ventilation effect is poor, and people after going out close door and window, when going home owing to close for a long time, air quality is relatively poor within doors, thereby can cause serious discomfort to people, give healthy working the mischief, cause that the people's dizziness that is within doors is uncomfortable in chest, vomiting etc.

The utility model content:

The purpose of this utility model provides a kind of air quality that can improve in the room, environmental protection, simple in structure and practical indoor air changer.

For achieving the above object, the technical solution of the utility model is: the indoor air changer of design, its main points are: comprise cylindrical case, in this shell, be set with the tubular movement, described movement one end is provided with filter screen, in this movement, be provided with circular-arc on light barrier and following light barrier, leave distance between light barrier and the following light barrier this on, and upward the surface area sum of light barrier and following light barrier is amassed more than or equal to the axial cross section of described shell.

The utility model is at creatively designing on the basis of shortcomings such as present IAQ difference, one of the utility model is installed in the below of an indoor side, another is installed in the top on opposite, because a lot of pernicious gases all are lighter than air, thereby it is indoor to make these pernicious gases discharge from superincumbent indoor air changer is installed, and utilize the formed air-flow rising principle of atmospheric difference, the indoor air changer of outdoor fresh air below being installed in the inlet chamber, the convection current of the existing room air of historical facts or anecdotes is changed, and makes indoor the pure and fresh of air that remain all the time.It is for the reliable installation of convenient realization the utility model and body of wall that cylindrical case is set in the above structure, can effectively avoid in short grained material or the inlet chambers such as small worm and mosquito and be provided with filter screen at movement one end; In movement, be provided with in the utility model circular-arc on light barrier and following light barrier can play the effect of protecting privacy, shutting out the light; The surface area sum of light barrier and following light barrier is long-pending more than or equal to the axial cross section of described shell in the design, can either allow pass through in the utility model in the air, realizes replacing; Can allow the people of outside can't see indoor situation again.

In order to realize the utility model intake and exhaust size and the adjusting of closing, radially be fixed with back shaft in described movement other end end, on this back shaft air door is housed, described air door is made of left and right air door, and this left and right air door is installed on the described back shaft through loose-leaf.It is folding for the ease of air door that above structure is designed to left and right air door with air door.

For the ease of spurring left and right air door, on described left and right air door, all be fixed with handle.

Be fixed with stop screw in the movement end that air door one end is installed, this stop screw retaining is outside described air door.

Described air door is a circular configuration, and the surface area of this air door to equal the axial cross section of shell long-pending, above structure can realize when air door is closed stuffy.

Describedly go up light barrier and following light barrier is semi-circular structure, and the axial cross section that the surface area sum that should go up light barrier and following light barrier equals described shell amasss the smooth and easy convection current that above structure both can realize indoor-outdoor air, also can with the protection privacy that OK.

In order to prevent in the indoor large object inlet chamber, be fixed with a gear thing post near on the outer casing end of described filter screen one end.

Have effluent trough at the outer casing underpart near described filter screen one side, above structure can be discharged water when water droplet occurring in the utility model timely.

Effect of the present utility model: the utility model novelty simple in structure, the utility model is installed on the body of wall, can realize the renewal often of room air, thereby effectively avoid the infringement of pernicious gas health; An advantage of the present utility model is to realize by any power the having characteristics of environmental protection and energy saving.
