Description
Technical field
The utility model relates to a kind of filter, in particular to a kind of light-duty primary filters.
Background technique
Primary filter is chiefly used in the primary filter of air-conditioning, ventilating system, is mainly used for the dust grain of 5 μm of filtering or more
Son, is typically provided the outline border for installing filter core, and common filter core is then the fiber filter material being packed into outline border with folded form
Expect, the dust particle in the air of inflow is effectively blocked between pleat and pleat by filter core.
As shown in Figure 1, primary filter in the prior art mostly makes filter core using softer fiber filter material, therefore
It can be using the outline border 1 ' of the production larger area of the hard material such as hardboard, plastics, metal, so as to filter core 2 ' and the use of being formed
Installation, and it also requires setting is used to enhance the iron net or bracket 3 ' of 2 ' stiffness of filter core in outline border 1 '.
As described above, the structure of primary filter in the prior art is more complicated, cause its volume and weight all excessive,
And production cost is excessively high.
Utility model content
The utility model provides a kind of light-duty primary filter, master to overcome above-mentioned prior art shortcoming
To use the following technical solution.
A kind of light-duty primary filter, including outline border and the filter core being fixed in outline border, filter core is using folded form
The fiber filter material being packed into outline border, the outline border are laminated using material identical with filter core, and inner wall is equipped with and is used for
Hot melt adhesive is perfused in the encapsulating portion of connection and enhancing and the junction stiffness of filter core, encapsulating portion.
Preferably, the outer wall of the outline border is equipped with the encapsulating portion for enhancing the stiffness of itself, the perfusion of encapsulating portion for one week
Hot melt adhesive.
Optionally, the encapsulating portion for enhancing the stiffness of itself, encapsulating portion perfusion hot melt are equipped at the folding line of the filter core
Glue.
Optionally, the surface of the filter core is equipped with the encapsulating portion of a plurality of stiffness for enhance itself orthogonal with folding line,
Hot melt adhesive is perfused in encapsulating portion.
Compared with prior art, the utility model has the beneficial effects that: outline border is made of material identical with filter core
Thin slice, and it is equipped with the encapsulating portion of enhancing stiffness, hot melt adhesive, the dry and hard after-hardening of hot melt adhesive, so that primarily efficient filter is perfused in encapsulating portion
The frame structure of device realizes lightness, while keeping preferably support stiffness to filter core, significantly reduces primarily efficient filter
The volume and weight of device, saves production cost.
The utility model is described further with embodiment with reference to the accompanying drawings of the specification.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of primary filter in the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the structural schematic diagram of the filter core of the utility model.
Specific embodiment
As shown, a kind of light-duty primary filter, including outline border 1 and the filter core being fixed in outline border 12, filter core 2 is
Fiber filter material in outline border 1 is packed into using folded form, the outline border 1 is laminated using material identical with filter core 2,
Its inner wall is equipped with for connecting and enhancing the encapsulating portion 31 with the junction stiffness of filter core 2, and hot melt adhesive is perfused in encapsulating portion.
Preferably, the outer wall of the outline border 1 is equipped with the encapsulating portion 32 for enhancing the stiffness of itself for one week, encapsulating portion is filled
Heat injection melten gel.
Optionally, the encapsulating portion 33 for enhancing the stiffness of itself, the perfusion of encapsulating portion are equipped at the folding line 21 of the filter core 2
Hot melt adhesive.
Optionally, the surface of the filter core 2 is equipped with the encapsulating of a plurality of stiffness for enhance itself orthogonal with folding line 21
Hot melt adhesive is perfused in portion 34, encapsulating portion.
The light-duty primary filter of one of above embodiment, its working principle is that:
(1) outline border 1 is laminated using material identical with filter core 2, so that 1 structure of outline border of primary filter realizes
Lightness significantly reduces the volume and weight of primary filter, saves production cost.
(2) 1 inner wall of outline border is equipped with for connecting and enhancing the encapsulating portion 31 with the junction stiffness of filter core 2, outline border 1 it is outer
It is equipped within wall one week the encapsulating portion 32 for enhancing the stiffness of itself, encapsulating portion is perfused hot melt adhesive, the dry and hard after-hardening of hot melt adhesive, because
This can keep filter core 2 preferably to support stiffness.
(3) the encapsulating portion 33 for enhancing the stiffness of itself is equipped at the folding line 21 of filter core 2, it is also an option that in the filter
The encapsulating portion 34 of a plurality of stiffness for enhance itself orthogonal with folding line 21 is arranged in the surface of core 2, and hot melt adhesive is perfused in encapsulating portion,
The dry and hard after-hardening of hot melt adhesive can effectively promote the stiffness of filter core 2 itself.
For those skilled in the art, it can be obtained according to the revealed structure of the utility model and principle other each
Kind is corresponding to be changed and deforms, and all these change and deform the protection category for belonging to the utility model.
