Internal portion's fitting is provided with filter core, and the side border of filter core is enclosed with seal, and filter core is bonded with the inner wall of seal and cavity
Connection.
As the improvement of such scheme, the seal is non-woven fabrics.
Further as such scheme is improved, and the non-woven fabrics is bonded by hot melt adhesive and the housing cavity.
As the improvement of such scheme, the material of the filter core is ultra-fine fibre glass filter paper.
, should present invention also offers a kind of method that can be used for making the lung ventilator filtration apparatus described in above-mentioned any one
Production method includes the following steps：
Make filter paper；
Hot melt adhesive liquid is heated, bonding edge sealing is carried out to filter core using seal；
The outlet air surface of housing is inserted in assembling device, by loading housing under filter core is put into assembling device gently；
Hot melt adhesive sealing is squeezed into the contact jaw of housing and filter core.
As the improvement of such scheme, filter paper complete after to connecting the filter core cutting formed by filter paper, concentration is put.
As the improvement of such scheme, before edge sealing, hot melt adhesive is squeezed into filter paper fold gap and is separated.
As the improvement of such scheme, using hot melt adhesive by before non-woven fabrics and filter core bonding edge sealing, hot melt adhesive is heated to
To 130 ± 5 DEG C.
Further as such scheme is improved, and gluing is carried out again after hot melt adhesive is heated to 170 DEG C ± 5 DEG C before sealing
Sealing.
As the improvement of such scheme, after the completion of hot melt adhesive sealing is squeezed into, in the outlet air face paste of lung ventilator filtration apparatus
Fill sealing joint strip.
The method have the benefit that：Pass through the side border environmental sealing part in filter core so that filter core with shell
Operation is easier during progress adhesive seal between body, and sealing is relatively reliable.
Brief description of the drawings
For the technical solution in the clearer explanation embodiment of the present invention, make required in being described below to embodiment
Attached drawing briefly describes.
Fig. 1 is a kind of schematic diagram of embodiment of lung ventilator filtration apparatus of the present invention；
Fig. 2 is a kind of schematic diagram of embodiment of strainer of the present invention；
Fig. 3 is the assembling schematic diagram of lung ventilator filtration apparatus of the present invention.
Embodiment
Carried out with reference to embodiments with the technique effect of design of the attached drawing to the present invention, concrete structure and generation it is clear,
It is fully described by, to fully understand the purpose of the present invention, scheme and effect.It should be noted that in the case where there is no conflict originally
The feature in embodiment and embodiment in application can be mutually combined.In addition upper and lower, left and right used in the present invention etc.
Describe in only opposite figure for the relation of each part mutual alignment of the invention.
Fig. 1 is a kind of schematic diagram of embodiment of lung ventilator filtration apparatus of the present invention, and Fig. 2, which is that filter core is a kind of in Fig. 1, to be implemented
The schematic diagram of mode, with reference to figure 1 and Fig. 2, lung ventilator filtration apparatus includes housing 1 and filter core 2, and housing 1 is the chamber of both ends open
Body, filter core 2 are ultra-fine fibre glass filter paper, and filter paper 11 is by folding, multiple are spaced connection and form multiple filtration structure,
Fold the filter paper fold gap formed and squeeze into hot melt adhesive liquid so that its unfolded state of filter core can be permanent holding, obtains best
Filter effect；By the sidepiece environmental sealing part in filter paper 11, multiple are spaced to the multiple filtration structure to be formed and passes through heat
Melten gel liquid is bonded as one, and improves the overall stability of structure, and ensures the close of filter paper 11 and 12 corner junction of seal
Reliability is sealed, more when filter core 2 is loaded 1 inside of housing, due to being enclosed with seal 12 in the outside of filter core 1 so that
Filter core 2 is bonded more smooth-going with the inner cavity of housing 1 closely, more during being bonded using hot melt adhesive, due to close
Filter core 2 is rolled into an overall structure by sealing 12 so that hot melt adhesive need to be only squeezed at 1 both ends open of housing makes its bonding close
It can ensure the reliability of Filter overall sealing installation, solve the problems, such as that multigroup filter paper bonding is illusive.
It is non-woven fabrics as preferred embodiment seal 12, the light easily setting of non-woven fabrics, drying is breathed freely, nontoxic stingless
Swash property, while also there is antibacterial, the characteristic of anti-chemical reagent, largely facilitate the setting of filter core, and in certain journey
The clean hygiene of filter paper is ensured on degree.
Present invention also offers a kind of lung ventilator filtration apparatus production method, specifically comprise the following steps：
The filter core that the filter paper being spaced apart by superfine fibre folded filter paper, multi-disc is formed is cut, concentration is put, just
In being uniformly processed, packaging efficiency is improved.
Hot melt adhesive liquid is heated to 130 ± 5 DEG C, glue is smeared in the installation position of seal and filter core, seal bag
It is rolled in filter core sidepiece border so that the filter paper that multi-disc is spaced apart is connected as one formula structure, completes the edge sealing operation of filter core, increases
The stability of strong filter cartridge construction, is non-woven fabrics as preferable seal.Then, the outlet air surface of housing 1 is inserted in assembling device
3, filter core 2 is put into assembling device 3 and gently loads enclosure interior by filter core down so that filter core 2 and the upper surface 31 of assembling device 3
Support and be installed in place.
Next, hot melt adhesive is heated to 170 DEG C of ± 5 DEG C of progress gluing sealings, beaten in the junction of filter core 2 and housing 1
Enter fluid sealant, after the gluing for completing one side, housing 1 is removed together with filter core 2 after glue bonding is firm, another side is beaten
Glue operates, and then completes the installation operation of filter core 2, since filter core by non-woven wraps forms overall structure, it is only necessary to by filter core 2
Air inlet and the sidepiece of air outlet and the inner cavity adhering and sealing of housing 1 it is firm, you can ensure filtration apparatus sealing reliability,
It is simple and efficient to handle.
Finally, sealing joint strip 32 is placed in assembling device 3, lung ventilator filtration apparatus outlet air surface is buckled in assembling device
The upper bonding for completing sealing joint strip 32.The making of lung ventilator filtration apparatus is ended herein.
