Abstract
The utility model discloses a kind of sealing structures of RO filter core, including shell, the pipe fitting for inflow and outflow is provided on the shell, the periphery set of the pipe fitting is provided with seal ring assembly, pipe fitting periphery in the utility model does not have spue line, influence of the spue line to sealing is avoided, guarantees the strainability of RO filter core.
Description
Technical field
The utility model relates to a kind of sealing structures of RO filter core, belong to water purification industry.
Background technique
RO filter core is the core element of water purifier, mainly water removal in large granular impurity, colloid, microorganism, organic matter,
Heavy metal etc., sealing performance directly affects filtration Quality.But the disengaging water nozzle in existing RO filter core be all using groove and
Sealing ring cooperation realize sealing, with specific reference to Figure of description Fig. 1, but this mode is in process of production, disengaging water nozzle at
There are spue line when type, spue line influences the risk of product hermeticity energy, and in every bacterium colony test such as Escherichia coli, there are bacterium
Fall the risk of precipitation.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of sealing structures of RO filter core.
The utility model is achieved through the following technical solutions:
A kind of sealing structure of RO filter core, including shell are provided with the pipe fitting for inflow and outflow, institute on the shell
The periphery set for stating pipe fitting is provided with seal ring assembly.
In the utility model embodiment, the pipe fitting is cylindrical tubular member.
In the utility model embodiment, the seal ring assembly includes the connection ring for being set in pipe fitting periphery, the connection
Ring top and bottom, which couple, the sealing ring for being set in pipe fitting periphery.
In the utility model embodiment, the pipe fitting lower end is provided with boss, and the seal ring assembly is located above boss,
Pipe fitting periphery above seal ring assembly has been located at compression ring.
A kind of sealing structure of RO filter core of the utility model, having the following beneficial effects: reduces production difficulty, keeps away
Exempt from influence of the spue line to sealing, guarantees the strainability of RO filter core.
Detailed description of the invention
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the schematic diagram of the prior art.
Fig. 2 is the schematic diagram of the utility model.
Fig. 3 is the explosive view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Reference book attached drawing, a kind of sealing structure of RO filter core, including shell 10, be provided on the shell for into
The periphery set of water and the pipe fitting of water outlet 20, the pipe fitting is provided with seal ring assembly 30.Specifically: the pipe fitting is column tube
Part, generally pylindrical pipe fitting, in production, the pipe fitting periphery do not carry out the processing of groove, that is to say, that outside the pipe fitting
Peripheral wall is smooth surface, without spue line.
Further, the seal ring assembly includes the connection ring 31 for being set in pipe fitting periphery, the connection ring upper end and
Lower end, which couples, the sealing ring 32 for being set in pipe fitting periphery, and in specific production process, connection ring and sealing ring are one
Manufacture uses soft material.
In one preferred embodiment of the utility model, the pipe fitting lower end is provided with boss 21, and the seal ring assembly is located at
Above boss, the pipe fitting periphery above seal ring assembly has been located at compression ring 40, in specific assembling process, will seal
Coil assembly is inserted in pipe fitting periphery, and boss plays the role of a limit, contacts underlying sealing ring with the surface of boss,
And compression ring is used in the top of seal ring assembly, guarantee that seal ring assembly will not move up and down, realizes positioning.
In the utility model: 1, the groove that original pipe fitting periphery is arranged being changed to sealing column sealing, improve sealing ring note
Moulding spue line influences sealing risk；2, two sealing rings change disjunctor；3, top increases compression ring.
The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new
Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups
Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein
Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then
It all should be in the protection scope of the appended claims for the utility model.
