Description
Technical field
The utility model relates to a kind of air freshening devices, particularly relate to fresh air purifier.
Background technique
New blower generally all has outdoor circulation path and indoor circulation access, and one end of outdoor circulation path is equipped with outdoor
Air inlet, the exterior objects such as leaf enter in order to prevent, usually filter screen are installed on outdoor air inlet, although this filter screen
Structure is simple, cost is very low, but it is when in use, and the effect is unsatisfactory.In order to be lifted into the air of outdoor circulation path
Quality, also occurs currently on the market, the filter device of structure of filter bag installs structure of filter bag additional near outdoor air inlet.I
Know that the mesh of filter bag is all very thin, therefore, this structure can cross most fugitive dust in air filtering.
Although the dust-proof effect of structure of filter bag is outstanding, since the mesh of filter bag is intensive, air passes through filter bag
When, it will receive biggish resistance, in order to overcome these resistances, it usually needs a powerful blower is cooperated, this just makes
Power consumption is obtained to obviously increase.
Utility model content
The utility model provides fresh air purifier, and its object is to overcome the above problem of the existing technology.
For the attainment of one's purpose, the technical scheme that the utility model is provided is as follows:
Fresh air purifier, it includes outdoor circulation path, which has outdoor air inlet, and the room
External circulation path is equipped with filter, and for the filter close to outdoor air inlet, it includes filter bag frame and multiple filter bags, the filter bag
Frame is fixed in indoor circulation access, and the filter bag frame is equipped with multiple mounting holes, and the upper end opening of the filter bag, lower end is closed
It closes, and the open end of each filter bag is individually fixed on the mounting hole of filter bag frame, the circular in cross-section of the filter bag, and is filtered
The diameter and length ratio of bag are less than or equal to 1/3.The filter bag of this ratio can reduce air by when the resistance that is subject to, so just
The power of blower can be reduced, to reduce power consumption.
Further, the diameter of the filter bag changes along the length direction of filter bag, is subject to the flow direction of air, described
Filter bag successively includes leading portion filter bag, middle section filter bag and back segment filter bag, and the leading portion filter bag is cylindrical, its diameter and filter bag
The diameter of open end is identical；The middle section filter bag is in cone, its reduced diameter；The back segment filter bag is spherical in shape,
Its diameter first increases, and is closed in rearmost end.The filter bag of this structure has clear advantage, it can take full advantage of air
Principle of dynamics when air is through filter bag, will ensure that the air drag of entire filter bag surface is equal, so that air be made equably to flow
The whole surface of filter bag, thereby it can be assured that dust is evenly distributed in the surface of filter bag.It is not in that dust concentrates on
Somewhere, the case where leading to dust local accumulation generation.
Further, the length ratio of the leading portion filter bag, middle section filter bag and back segment filter bag is 1:3:1.
Using technical solution provided by the utility model, compared with prior art, have the following beneficial effects:
The filter of structure of filter bag is arranged in the utility model at outdoor air inlet, can carry out to the air entered the room
Preliminary and effective dust removal and filtration；Meanwhile the circular in cross-section of filter bag, and the diameter of filter bag and length ratio, be less than etc.
In 1/3.The filter bag of this ratio can reduce air by when the resistance that is subject to, the power of blower can be reduced in this way, to subtract
Few power consumption.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one.
Fig. 2 is the schematic perspective view of one filter of embodiment.
Fig. 3 is the structural schematic diagram of preferred embodiment.
Fig. 4 is the filter structure schematic representation of preferred embodiment.
Fig. 5 is the structural schematic diagram of filter bag.
It illustrates: circulation path outside Room 1,2 filters, 21 filter bag frames, 22 filter bags, 23 mounting holes, 221 leading portion filter bags,
222 middle section filter bags, 223 back segment filter bags.
Specific embodiment
For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with the embodiments, it is real below
Example is applied for illustrating the utility model, but is not intended to limit the scope of the present invention.
Embodiment one
Referring to Fig.1, fresh air purifier, it includes outdoor circulation path 1, which has outdoor air inlet
(being not drawn into figure), and the outdoor circulation path 1 is equipped with filter 2, and close to outdoor air inlet, it is wrapped the filter 2
Filter bag frame 21 and multiple filter bags 22 are included, the filter bag frame 21 is fixed in indoor circulation access 1, and the filter bag frame 21 is equipped with more
A mounting hole 23, the upper end opening of the filter bag 22, lower end closure, and the open end of each filter bag 22 is individually fixed in filter bag frame
On 21 mounting hole 23, the circular in cross-section of the filter bag 22, and the diameter of filter bag 22 and length ratio, it is less than or equal to 1/3.
The filter bag 22 of this ratio can reduce air by when the resistance that is subject to, the power of blower can be reduced in this way, to reduce consumption
Electricity.
Preferred embodiment
Referring concurrently to Fig. 3, Fig. 4 and Fig. 5, the present embodiment is essentially identical with above structure, and the main distinction is this implementation
The filter 3 of example also includes filter frame 21 and filter bag 22, but the diameter of the filter bag 22 of the present embodiment is along the length direction of filter bag 22
Variation, is subject to the flow direction of air, and the filter bag 22 successively includes leading portion filter bag 221, middle section filter bag 222 and back segment filter
Bag 223, the leading portion filter bag 221 is cylindrical, its diameter is identical with the diameter of 22 open end of filter bag；The middle section filter bag
222 in cone, its reduced diameter；The back segment filter bag 223 is spherical in shape, its diameter first increases, and last
End closure.Preferably, the length ratio of the leading portion filter bag 221, middle section filter bag 222 and back segment filter bag 223 is 1:3:1.It is this
The filter bag 22 of structure has clear advantage, it can take full advantage of aerodynamic principle, will be true when air is through filter bag 22
The air drag for protecting entire 22 surface of filter bag is equal, therefore, can be with so that air be made to flow evenly through the whole surface of filter bag 22
Ensure that dust is evenly distributed in the surface of filter bag 22.Be not in that dust concentrates on somewhere, lead to dust local accumulation
It happens.
The utility model is described in detail in conjunction with the embodiments above, but the content be only the utility model compared with
Good embodiment, should not be considered as limiting the scope of the present invention.It is made according to the scope of application of this utility model
All the changes and improvements etc. should all be still fallen within the patent covering scope of the utility model.
