Embodiment

Fig. 1 is the structure diagram of the folding air filter 100 in the utility model embodiment；Fig. 2 is Fig. 1 along A- The sectional view of A lines.It refer to Fig. 1, Fig. 2, the folding air filter 100 in the present embodiment includes frame 10, first and filters Piece 20a and the second filter 20b.

Frame 10 includes indulging frame 12a, the second vertical frame 12b by the first of parallel interval and is vertically connected at the first vertical frame 12a and second indulges the rectangular outer frame 10a that two horizontal frames 11 between frame 12b are formed by connecting and two rows of parallel intervals are connected to the One vertical frame 12a and second indulges the supporting rod 13 between frame 12b.Two rows of supporting rods 13 stagger along the height of rectangular outer frame 10a to interval It sets, supporting rod 13 is made to be serrated distribution.First vertical frame 12a possesses the hollow structure of accommodating chamber Q1, accommodating chamber Q1 for inside For can opening and closing structure.Optionally, the one side of the first vertical frame 12a is that can open the shutter door M1 of accommodating chamber Q1, it is necessary to Shi Ketong The opening and closing of shutter door M1 is crossed to insert the first filter 20a or the second filter 20b.And first the width of vertical frame 12a set inwardly Put the first gap f1 of perforation accommodating chamber Q1.Second vertical frame 12b has wide the second gap f2 to perforation.Optionally, square is formed The horizontal frame 11, first of shape outline border 10a is indulged between frame 12a, the second vertical frame 12b by being welded together.

The first filter 20a fixations in the present embodiment, which are covered, to be connected within frame 10, empty on the inside of covering rectangular outer frame 10a Between.And first one end of filter 20a be through at the second gap f2, the other end passes through the first gap f1, and detachably connected the One end of two filter 20b.First filter 20a is successively from the high outward around each supporting rod 13, shape of rectangular outer frame 10a Toothing banded structure.Second filter 20b is contained in accommodating chamber Q1, and its one end is through at the first gap f1 and detachable Connect one end of the second filter 20b.

In an embodiment of the present embodiment, optionally, frame 10 is made of aluminium alloy or galvanized sheet.First filtering Piece 20a and the second filter 20b are made of activated carbon filtering cloth.

During 100 normal use of folding air filter in the present embodiment, the second filter 20b is contained in accommodating chamber Q1 In wouldn't be used to filter.First filter 20a, which covers to be connected in frame 10, excessively to be filtered.

When the first filter 20a using needing replacing for a period of time, the company of the first filter 20a and frame 10 is unclamped It connects, the first filter 20a is outwards extracted out from the second gap f2.On the one hand, the first filter 20a is extracted out from the second gap f2, On the other hand the second filter 20b is taken out of by the first filter 20a, the second filter 20b can be made to bypass each support successively Bar 13 forms zigzag banded structure, and at the space in covering framework 10.Then the second filter 20b is fixed on frame 10 On, and remove the first filter 20a and cleaned.

After the completion of first filter 20a cleanings, insert again in accommodating chamber Q1, and pass through first gap f1 the second mistakes of connection Filter disc 20b.When the second filter 20b needs cleaning, the first filter 20a is taken out of by the second filter 20b, it is so anti- Multiple, filter changes clothes that operation is very easy, and main actions are only simple extraction and connection.

With continued reference to Fig. 2, in an embodiment of the present embodiment, the second filter 20b builds up zigzag and is placed in appearance It receives in the Q1 of room.In other embodiments, the second filter 20b can be also placed in accommodating chamber Q1 around scroll, to facilitate second Filter 20b is subject to the first gap f1 pull-outs.Optionally, the first gap f1 is obliquely installed, and is connected along the first filter 20a The tangential direction at end is connect, further facilitates the smooth pull-out of the second filter 20b.

In an embodiment of the present embodiment, optionally, the second filter 20b includes several length and is equal to the first mistake The segment of filter disc 20a is detachably connected between each segment.By setting multiple segments being detachably connected, one is extracted out every time A segment uses, and is cleaned together after can repeatedly replacing, using more convenient time saving.

In an embodiment of the present embodiment, the both ends of the first filter 20a are detachable by fixing screws respectively It is connected to the first vertical frame 12a and second and indulges frame 12b.When needing replacing filter, fixing screws are first unclamped, are then carried out more It changes.

In summary describe, there is the folding air filter 100 in the present embodiment filter to change clothes easy to operate, energy The advantageous effect enough recycled.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
