Background technique
Fig. 1 is the schematic diagram of reverse-osmosis membrane element in existing plug-in household reverse osmosis membrane filter.As shown in Fig. 1, instead
Converter 101, white glue cloth 102, reverse osmosis membrane body 103 form permeable membrane device by water, and reverse osmosis membrane body 103 is usually by center
Multiple film bags and outer layer glue the band composition manage, being spirally wound on central tube.The purposes of outer layer glue band, which is wound around, seals up spiral shell
The film bag for revolving shape forms spiral helicine water inlet flow channel and produces water flow passage, and the purposes of white glue cloth 102 is fixed waterway converter 101,
Raw water and concentrated water are strictly distinguished.One of glue raw material of 102 backside coating of outer layer glue band and white glue cloth are volatile phenol,
In safe and healthy Soak Test, cause volatile phenol exceeded；If in addition the winding of white glue cloth 102 bonding is not tight, there are in filter core
It leaks out danger.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of without coating glue, safe and healthy reverse osmosis
Membrane component and its sealing shroud.
In order to solve the above technical problems, the utility model uses technical solution as described below:
A kind of sealing shroud of reverse-osmosis membrane element comprising have the sealing shroud main body of a hollow cylinder shape, the sealing shroud
Body top periphery is provided with O-ring seal, and the sealing shroud main body and the O-ring seal use macromolecule food grade materials
It is integrally formed.
Preferably, the macromolecule food grade materials are solid silicone, liquid silica gel or polyurethane.
Preferably, the top of the sealing shroud main body is provided with an end face, and it is reverse osmosis for avoiding which offers one
The avoid holes of the central tube of membrane body.
Preferably, the number of the O-ring seal is 2.
A kind of reverse-osmosis membrane element includes a reverse osmosis membrane body, a water route connecting with described reverse osmosis membrane body one end
Converter and one be socketed on the reverse osmosis membrane external surface sealing shroud, which includes a hollow cylinder shape
Sealing shroud main body, the sealing shroud body top periphery are provided with O-ring seal, the sealing shroud main body and the O-ring seal
It is integrally formed using macromolecule food grade materials.
Preferably, the reverse osmosis membrane body includes a central tube and multiple films being spirally wound on the central tube
Bag.
The advantageous effects of the utility model are: above-mentioned reverse-osmosis membrane element by macromolecule food grade materials one
Molding sealing shroud is not necessarily to the glue of backside coating, is lived reverse osmosis membrane body surface face fit sealing using the elasticity of itself, makes anti-
The wholesomeness of permeable membrane device is effectively ensured；In addition, the O-ring seal that sealing shroud is included, auxiliary without white glue cloth
Sealing is helped, assembling technology procedure is simplified, while having prevented to produce due to the bonding of white glue cloth, outer layer glue band is not tight in the prior art
It leaks out in raw reverse osmosis filter core danger.

Specific embodiment
To make those skilled in the art that the purpose of this utility model, technical solution and excellent be more clearly understood
Point is further elaborated the utility model below in conjunction with drawings and examples.
As shown in Figures 2 and 3, in the utility model one embodiment, reverse-osmosis membrane element includes a reverse osmosis membrane body
10, a waterway converter 20 and a sealing shroud 30, the reverse osmosis membrane body 10 include that a central tube 101 and multiple spirals twine
The film bag being wound on the central tube 101.The sealing shroud 30 is socketed on the outer surface of the reverse osmosis membrane body 10, the water route
Converter 20 is connect with one end of the reverse osmosis membrane body 10.
As shown in figure 4, the sealing shroud 30 includes the sealing shroud main body 301 of a hollow cylinder shape, sealing shroud master
301 upper periphery of body is provided with 2 O-ring seals 302, and the top of the sealing shroud main body 301 is provided with an end face 303, should
End face 303 offers the avoid holes 304 of a central tube 101 for avoiding reverse osmosis membrane body 10.The sealing shroud main body 301,
O-ring seal 302 and end face 303 are integrally formed using macromolecule food grade materials, and the macromolecule food grade materials are solid
Any one in body silica gel, liquid silica gel and polyurethane.
Multiple film bags are spirally wound on rolled anti-on central tube 101 by the reverse-osmosis membrane element first in assembly
Membrane body 10 is permeated, then the sealing shroud 30 of macromolecule food-grade is sleeved on to the surface of reverse osmosis membrane body 10, sealing shroud main body 301
Reverse osmosis 10 surface fit sealing of membrane body is lived using the elasticity of own material, it is safe and healthy without the glue of backside coating；Institute
The inner wall compression seal for stating O-ring seal 302 Yu waterway converter 20 allows raw water all to flow into reverse osmosis membrane body 10 and side does not occur
Stream avoids the interior danger of leaking out of reverse osmosis filter core.Since 301 own material of sealing shroud main body has certain shrinkage and softness
Degree, during assembling with waterway converter 20, the phenomenon that being also easy to produce downslide, end face 303 is sealing shroud main body in order to prevent
The limit design that 301, which glide, uses, avoids the risk leaked in reverse osmosis filter core from occurring.
The above is only the preferred embodiment of the present invention, rather than does limit in any form to the utility model
System.Those skilled in the art can impose various equivalent changes and improvement on the basis of the above embodiments, all to want in right
The equivalent variations or modification done in range are sought, should fall within the protection scope of this utility model.
