Description
Technical Field
The utility model relates to a technical field of air purifier filter screen indicates a foldable filter screen very much.
Background
A wide variety of filter screens, particularly for air cleaners, are widely used in the fields of home, industry, medical care, and the like. However, the filter screen for the air purifier is usually of an integrated structure, cannot be folded, occupies a large space in the transportation process, and is high in storage and transportation cost and not beneficial to reducing the product cost. Meanwhile, the filter screen for the air purifier is mainly a flat filter screen with single-side air inlet and a cylindrical filter screen with multi-side air inlet. The former has the advantages of large air inlet area, uniform resistance, convenient production and transportation and the like, but can only be used for single-side air inlet. Although the latter realizes multi-surface air intake, the defects of uneven wind resistance, low production efficiency, large transportation occupied space and the like exist.
Therefore, it is necessary to provide a technical means to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a realize like this, a foldable filter screen, its characterized in that: the folding filter screen comprises n square filter screens; wherein n is an even number of 4 or more; the n square filter screens are connected end to end through a folding piece, so that the n square filter screens are integrally a foldable n prism.
Preferably, the folding member comprises a first connecting part and a second connecting part which are movably connected with each other; one end of the first connecting portion is connected with the previous square filter screen, and one end of the second connecting portion is connected with the next square filter screen.
Preferably, the number of the square filter screens is four, and the four square filter screens are integrally foldable quadrangular prisms.
Preferably, six square filter screens are arranged, and the six square filter screens are integrally foldable hexagonal prisms.
Preferably, a connecting member for connecting with the outside is provided on both sides of one of the square screens.
The utility model relates to a folding filter screen, through setting n square filter screens into a folding n prism, on one hand after the filter screen is folded, can pack many filter screens together, can effectively reduce the occupation space in transit, reduce and store and transport the cost, help to reduce the cost of the product; on the other hand, the advantages of multi-surface air inlet and large filtering expansion area of the cylindrical filter screen are also embodied, and the expansion area is larger than that of the cylindrical filter screen in the same adaptive space, so that the realized CADR (clean air volume) is larger.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
The following is a first embodiment disclosed in the present invention, as shown in fig. 1 and fig. 2, a foldable filter net 1, the foldable filter net 1 includes four square filter nets 11; the four square filter screens 11 are connected end to end through a folding piece 12, so that the four square filter screens 11 are integrally a foldable quadrangular prism. More specifically, the frame of the square filter screen 11 may be a paper frame, or may be a frame made of other materials, such as injection molding or plastic sheet or aluminum profile. In addition, the square filter screen 11 may be a single-effect HEPA filter screen, a single-effect activated carbon filter screen, a single-effect screen with a screen or other porous structures, a composite filter screen (including a primary effect HEPA and activated carbon filter layer), or the like. Further, the folding member 12 includes a first connecting portion 121 and a second connecting portion 122 movably connected to each other; one end of the first connection portion 121 is connected to the previous square screen 11, and one end of the second connection portion 122 is connected to the next square screen 11. Further, the folding member 12 may be formed integrally with the two adjacent square screens 11. Further, one of the square screens 11 is provided at both sides with a connector 13 for connection to the outside.
The following is a second embodiment disclosed in the present invention, which has substantially the same technical features as the first embodiment, and the differences are: six square filter screens 11 are arranged, and the six square filter screens 11 are integrally foldable hexagonal prisms.
The utility model relates to a folding filter screen 1, through setting n square filter screens 11 into a folding n prism, on one hand after the filter screen is folded, can pack many filter screens together, can effectively reduce the occupation space in transit, reduce and store and transport the cost, help to reduce the cost of the product; on the other hand, the advantages of multi-surface air inlet and large filtering expansion area of the cylindrical filter screen are also embodied, and the expansion area is larger than that of the cylindrical filter screen in the same adaptive space, so that the realized CADR (clean air volume) is larger.
The above description is only for the preferred embodiment of the present invention, and the structure is not limited to the above-mentioned shape, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
