Description
Technical field
This utility model relates to labor protection articles for use, is specifically related to a kind of filter box with foldable filter element.
Background technology
Face shield is a kind of air filter, for preventing the noxious substance in air, such as dust granule, cytotoxic chemical thing
Matter, antibacterial etc. enter the respiratory apparatus of human body.Suction-self filtering type against particle respirator have anti-dust, cigarette, mist, steam and
Tiny microorganism, installs activated carbon filter pulp additional and can protect abnormal flavour and effect of slight harmful gas.The anti-granule that people use at present
Thing respiratory organ, major part simple in construction only have filter pulp, filter effect is undesirable.Additionally, ventilation is little between filter pulp and filter box, long
Time wears hypopnea, symptom anoxia easily occur, feeling bad.Therefore, face shield should increase the filtration towards extraneous air
The surface area of device, in order to increase the air capacity being drawn into inside from outside, and slow down through the speed of air stream of filter.
Summary of the invention
This utility model, in order to solve conventional ventilators filter box simple in construction, poor filtration effect, the defect that ventilation is low, carries
For a kind of good filtration effect, increase the filter box with foldable filter element of extraneous air contact area.
This utility model realizes by the following technical solutions,
A kind of filter box with foldable filter element, including oval box body, the middle part of box body is provided with spiracle, in spiracle
It is provided with air valve, it is characterised in that described tray interior is provided with some cross support bodies, the fixing post that supporter is middle with spiracle
Fixing, it is provided with the top of some floors being connected with spiracle noncontact, described floor and supporter in the interval between supporter
End is generally aligned in the same plane, and the space between floor connects setting with spiracle；Arrange on the supporting surface that supporter and floor are formed
Foldable filter element with some folds.
For ease of fixing seal, the outside of described foldable filter element has been provided with sealing and the soft of fixing filter element effect is fixed
Limit.
Preferably, floor length is different, is crisscross arranged in the space between supporter.
Of the present utility model it is beneficial in that, utilizes the structure of floor and foldable filter element that filter filtration box within is filled
Put the contact area with air to increase, greatly improve ventilation, it is ensured that breathe smooth and easy during use, it is to avoid personnel's anoxia occurs
Phenomenon, simple in construction, with low cost, filter effect is better than plain filter, implements reliable, is suitable for promoting the use of.
Accompanying drawing explanation
The structural representation of Fig. 1 this utility model foldable filter element；
The cross-sectional view of Fig. 2 this utility model foldable filter element；
Fig. 3 this utility model supporting body structure schematic diagram；
1. fixed edge in figure, 2. foldable filter element, 3. supporter, 31. floors, 4. spiracle.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, this utility model provides a kind of filter box with foldable filter element, including oval box body,
The middle part of box body is provided with spiracle 4, is provided with air valve in spiracle, thes improvement is that tray interior is provided with some cross support bodies
3, the fixing post in the middle of supporter 3 and spiracle is fixed, and the middle part of spiracle 4 is provided with fixing post, and one end of supporter 3 is with fixing
Post is fixed, and the inwall of the other end and box body is fixed.
It is provided with some floors 31 being connected with spiracle noncontact, the top of floor 31 in the interval that supporter 3 is formed
It is generally aligned in the same plane with the top of supporter, forms a supporting surface.Space between floor 31 connects setting with spiracle；?
The foldable filter element 2 of some folds it is provided with on the supporting surface that support body and floor are formed.The filter paper of foldable filter element is that S-shaped is arranged,
Which increases filter area, improve ventilation.
In order to realize being in sealing contact of foldable filter element and box body, simultaneously working as the effect preventing it from deforming, described folding is filtered
The outside of core has been provided with sealing and the soft fixed edge 1 of fixing filter element effect.
In order to improve further, floor length is different, is crisscross arranged in the space between supporter.
When this utility model uses, the structure of floor and foldable filter element is utilized to make filter defecator within box and air
Contact area increase, greatly improve ventilation, it is ensured that breathe smooth and easy during use, it is to avoid the phenomenon of personnel's anoxia occurs, knot
Structure is simple, with low cost.
