Description
Technical field
The utility model relates to air-treatment fields, and in particular to a kind of for fixing the fixed structure of new blower.
Background technique
New blower is a kind of effective air cleaning facility, and room air can be made to generate circulation, on the one hand indoor dirty
Outdoor is discharged in turbid air, on the other hand outdoor ozone by sterilizing, after the measures such as disinfection, filtering, then is input to
Interior, allow all be all the time in room fresh clean air.New blower uses fresh air convection current patented technology, so that in room
In slight positive pressure state, to prevent outdoor airflow from entering from other mouthfuls, by independently blowing and air inducing, realize room air
Convection current, thus the carry out room air displacement utmostly changed, the guarantee of multifunctional purifying system is entered the room built in new blower
Air cleaning health.
Fresh air machine is broadly divided into the new blower of air-exhaust type and the new blower two types of blast type, in the new blower of fresh air formula again
It is divided into duct type fresh air and wall-mounted fresh air, comparatively duct type fresh air system is more suitable for greatly industry or big due to project amount
Area Office Area uses, and exists simultaneously duct type fresh air and wall-mounted fresh air in family at present, the new blower of duct type is long-term
When after can form dust stratification in the duct, and difficulty is cleaned, thus forming secondary pollution to room when used for a long time.Cause
This, more uses wall-mounted fresh air system in the family at present.
Wall-mounted new blower needs the fresh air outside sucking, it is therefore desirable to the aperture on wall, and aperture on wall
Consequent is external noise and pollution later.
Utility model content
Utility model aims to solve the external noise factors of new blower.
It provides first a kind of for fixing the fixed structure of new blower, is fixed on consolidating on wall including backboard and by backboard
Determine frame, is provided with mute cotton between the backboard and wall.The utility model not only utilizes the fixed function of backrest, while benefit
With the thickness of backrest, so that mute cotton can be put between wall and backboard, to realize while being fixedly secured of new blower
Noise-decreasing problem, and the problem that exterior object is entered by the gap of backrest in room has been isolated.
Between the mute cotton-wadded quilt pressure and backboard and wall.Mute cotton under compression, not only can solve sound insulation
Problem, while also acting and external particle object is prevented to enter in room by the gap of backrest, and reducing new blower and open
Vibrating noise when state, so that vibration problems caused by being rotated due to blower, are played slow by the mute cotton of backrest and compression
The effect of punching, reduces the Micro-friction of new blower and wall, to extend the service life of wall-mounted new blower.
2-6 times with a thickness of back plate thickness of the mute cotton under soft fluffy state.Mute cotton under this multiple
Effect be it is best, will not will not can not play original effect very little because of compression cotton because of too tight and bad dress is compressed.
It is provided in the backboard for the first opening by intake stack, the mute cotton is equipped with and the
The matched third opening of one opening.
The third opening is slightly less than the diameter of intake stack.When third opening is slightly less than intake stack, just have
A tensile force enables mute cotton preferably to wrap up pipeline.
Described first is open the cylinder being provided with to wall side with backboard uniform thickness.Cylinder can further be isolated
Block objects.
The diameter of the cylinder is slightly larger than the diameter of intake stack.Facilitate the set between cylinder and intake stack
It connects.
The third opening of the mute cotton is slightly less than drum diameter.
The utility model has the beneficial effects that
1. the utility model passes through the cooperation for cleverly utilizing mute cotton and backboard, so that extraneous noise will not pass through
Pipeline is transmitted in room, substantially increases the soundproof effect of blower；
2. the utility model accurately using the mute cotton of compression, not only solves noise problem, while utilizing compression shape
The damping effect of the mute cotton of state, so that microseismic activity when new fan operation is not transferred on wall, to extend fresh air
The service life of machine；
3. the utility model has certain elasticity using mute cotton, it is allowed to preferably wrap up intake stack, increases substantially
Soundproof effect.
