Description

TECHNICAL FIELD

[0001] The utility model relates to filter technical field, concretely is a kind of square tube type filter of air purifier. BACKGROUND

[0002] The filter of traditional air purifier is generally cylindrical due to different appearance designs and market positioning of various brands, and the air purifier matched with the cylindrical filter is generally square in shape. However, under the same parameter conditions, the performance of the cylindrical filter is slightly lower than that of the square filter. In order to improve the performance of the air purifier, the size and height of the filter must be increased, and finally the air purifier is very bulky and occupies a lot of space, which does not meet the general needs of modern customers. SUMMARY

[0003] The utility model provides a square tube type filter of air purifier to overcome the deficiencies of prior art, combines the original circular and square filters into a square tube type filter, the cross section is square, the four corners are rounded, the gas flow direction is from inside to outside, single-sided glue injection is adopted, and a metal mesh is added inside to ensure the shaping of the product and meet the strength requirements.

[0004] To achieve the above object, a square tube type filter of air purifier is designed, which comprises a filter. The filter comprises a metal mesh, filter glue, an edge covering, a coarse filter screen and a filter core. The filter is provided with an edge covering at both ends. The filter core is provided with a metal mesh inside. The metal mesh is connected at the head and tail to form a square tube shape. The four corners of the metal mesh are rounded. The filter core is provided with a coarse filter screen outside. The filter core is coated with filter glue inside.

[0005] The metal mesh material can be galvanized steel sheet or 304 stainless steel.

[0006] The head and tail connection of the metal mesh is connected by spot welding.

[0007] The filter core is a pleated filter core, which is connected at the head and tail to form a square tube shape. The four corners of the filter core are rounded. The inside of the filter core is injected with filter glue in multiple rows in the horizontal direction.

[0008] The edge covering can be a plastic frame or a paperboard frame.

[0009] Compared with the prior art, the utility model increases the filtering area in limited space, reduces the structural resistance of the filter, increases the air flow of the filter, improves the filtering and purifying effect, shapes the product by single-sided glue injection, ensures the strength by the metal mesh, increases the coarse filter screen at the outer ring to ensure the shape and filter large particles of hair, and prolongs the service life. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1The utility model discloses a structure schematic drawing.

[0011] Figure 2 It is the explosion drawing of the utility model.

[0012] Figure 3 It is the sectional view of the utility model.

[0013] Figure 4 It is filter core structure schematic drawing.

[0014] Referring to Figures 1 to 4 , 1 is metal net, 2 is filter rubber, 3 is edge covering, 4 is rough efficiency filter screen, 5 is filter core. Specific implementation

[0015] The utility model will be further explained according to the drawings.

[0016] As Figures 1 to 4 shown, the filter includes metal net 1, filter rubber 2, edge covering 3, rough efficiency filter screen 4, filter core 5, the filter both ends are equipped with edge covering 3, filter core 5 inside is equipped with metal net 1, metal net 1 head-to-tail connection surrounds square cylinder, the four corners of metal net 1 are rounded transition, and the material of metal net 1 can be galvanized steel sheet or 304 stainless steel, and the rust of the material can be prevented by the two kinds of materials, and metal net 1 head-to-tail connection is connected through spot welding, and the size of the mesh on the surface of metal net 1 is replaced according to product height and weight specification, and the higher the product height is, the heavier the weight is, so metal net 1 needs higher support strength, therefore the smaller the mesh of metal net 1 is selected, and conversely, the mesh of metal net 1 is not too large.

[0017] Filter core 5 is equipped with rough efficiency filter screen 4 outside, and rough efficiency filter screen 4 can adopt the material of PP or PET, and the PP material has excellent heat resistance, corrosion resistance and tensile strength, filter core 5 is coated with filter rubber 2 inside, and rough efficiency filter screen 4 can play a supporting role, and can also filter large-particle materials and hair, prolonging the service life of the filter.
