Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The embodiment provides a high-performance primary filter, as shown in fig. 1 and 3, which comprises an outer frame and a filter element, and is characterized in that the filter element is a three-layer composite filter material; the first layer 1 of the three-layer composite filter material is a socket-hole type filter material, the middle layer 2 is a fiber filter layer, and the bottom layer 3 is an anti-wind resistance protective layer; the three layers are bonded through high temperature.

The working principle of the technical scheme is as follows: the hole-shaped filtering material is a filtering material with a plurality of holes inside, can filter large particles and has a large space for containing dust particles in the thickness direction; the fiber filter layer is a commonly used fiber filter material and mainly aims at small particles; the wind resistance protective layer is a finger-shaped filter material which is reduced and is aimed at smaller particles, and because the first layer and the middle layer of the filter material can be inwards sunken under the action of wind power, the gap of the filter material is increased, so that blocked dust particles are separated from constraint and pass through the filter material, and therefore, the wind resistance protective layer can reduce the deformation of the first layer and the middle layer and simultaneously filter smaller particles.

The beneficial effects of the above technical scheme are: by using the three-layer composite filter material, not only the particles of the dust particles are filtered layer by layer, but also the particles of the dust particles are not only attached to the surface of the filter material but also adsorbed in the space of the filter material in the thickness direction, so that the filter material can adsorb more dust particles, the wind resistance of the filter material is increased slowly, and the dust particles attached to the filter material are not easy to be deformed and separated from the constraint to pass through the filter material. Thereby prolonging the service life of the filter material and reducing the replacement frequency of the filter material.

In one embodiment, the cellular filter material is an open cell sponge; the fiber filtering layer is made of fiber filtering cotton; the wind resistance protective layer is made of single-side lustre-finishing filter cotton.

The embodiment provides a specific composition of a three-layer composite filter material, and the open-pore sponge has light weight, low cost and more pores in the filter material; the fiber filter cotton is a common filter material, has stable performance and low price, and the fiber filter cotton containing low-melting-point fibers is used in the embodiment, so that the filter materials of the first layer and the bottom layer can be better bonded together through heating; the single-side lustre finishing filter cotton is fiber cotton subjected to single-side lustre finishing treatment, the fibers of the single-side lustre finishing filter cotton are more compact, smaller particles can be filtered, and the deformation of the single-side lustre finishing filter cotton in the plane direction of the filter material is small.

In one embodiment, the thickness of the first layer is 15mm, the thickness of the middle layer is 10mm, and the thickness of the bottom layer is 1 mm.

Because the dust particles filtered from the bottom layer 3 to the first layer 1 are from small to large, and the three-layer composite filter material can fully utilize the space in the filter material and prolong the service life of the three-layer composite filter material under the thickness of the three layers according to the proportion of different dust particles in the air under the current common condition.

In one embodiment, as shown in fig. 2, a strong magnet 4 is disposed between the first layer 1 and the middle layer 2.

In public places such as subways and high-speed railways, dust adsorbed in the filter material often shows black color because the composition of dust particles in the air in these places is different from that in the atmospheric environment, and it contains iron metal dust. This embodiment is through setting up strong magnet 4, can directly adsorb iron metal dust on the one hand, and on the other hand can make originally should be the iron metal dust according to inertial motion because strong magnet 4's appeal and deviate from former movement track to increase the route that iron metal dust moved in the filter media, thereby reinforcing adsorption effect.

In one embodiment, as shown in fig. 3 and 4, the outer frame includes: the first frame body 5, the middle part of the first frame body 5 is provided with a metal net 6; the first frame body 5 and the second frame body 7 are hinged through a hinge 8 on one side and detachably connected on the other opposite side; magic tapes 9 are arranged on the upper side and the lower side of the second frame body 7, corresponding magic tapes 9 are arranged on two opposite side edges of the bottom layer 3, and the three-layer composite filter material can be attached to the second frame body through the magic tapes after being unfolded and tensioned.

The working principle of the technical scheme is as follows: in public places with large flow of people and complex environment, the filter element has more dust particles, the service life of the filter element is low, and the replacement frequency is higher, so the embodiment provides the outer frame with the filter material easy to replace. A user can conveniently attach the filter material to the second frame body 7 through the magic tape by a single person, then the first frame body 5 and the second frame body 7 are closed around the hinge 8 and then locked on the opposite side frames, so that the filter element is conveniently and quickly replaced, and the replaced filter element is very flat due to the fact that the magic tape is used for fixing; meanwhile, the metal net is arranged on the first frame body 5, so that the filter element can be protected from collision, and large particles or suspended matters such as mosquitoes, leaves, poplar catkins and the like can be intercepted.

The beneficial effects of the above technical scheme are: the utility model provides a can the quick replacement filter core frame technical scheme, and the metal mesh can intercept big particulate matter or suspended solid when protecting inside filter core.

In one embodiment, as shown in fig. 5, the middle of each frame of the second frame body facing one side of the first frame body is provided with an adhesive tape 10.

Because, the filter core is easy to compress in the thickness direction generally, so under long-time wind-force effect, the edge of filter core can slowly move to the frame is interior, breaks away from the centre gripping of first framework 5 and second framework 7 even, through setting up adhesive tape 10, can make the filter core cross-section of adhesive tape 10 outside in the frame be greater than the cross-section of adhesive tape 10 centre gripping to make the difficult inward shift of filter core, thereby press from both sides tight filter core.

In one embodiment, the detachable connection is a snap-fit connection.

This embodiment provides a can dismantle the mode of connection, and the hasp opens and shuts easily and connect stably, is of value to quick replacement filter core.

In one embodiment, the outer frame is made of iron.

The outer frame is made of metal, so that the frame is more durable.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
