Abstract
A kind of RO film leakage-proof Sealing, comprise the ring body and the guide ring that are provided with center hole, the lower end of ring body is connected with the upper end of guide ring, the sidewall of guide ring is to the direction projection away from ring body axis, and form annular groove in the inner side of guide ring, the lower end of ring body extends to form annular wall downwards along the direction of axis, and annular wall is positioned at the inside of guide ring.The utility model is owing to having adopted annular wall, when RO film leakage-proof Sealing is arranged on RO film, the former water flowing between guide ring and RO film applies a power to the sidewall of annular wall under the effect of pressure, thereby annular wall is more closely arranged on the outer surface of RO film, and the lower end surface of annular wall is that conical surface or lower end surface are vertical with axis, the former water that is positioned at like this annular wall lower end just can not make annular wall occur channeling water point, has the advantages such as simple in structure, easy to use and good sealing effect.
Description
Technical field
the utility model relates to household water filter technical field, relates in particular to a kind of RO film leakage-proof Sealing being applied in water purifier.
Background technique
Sealing is to prevent that fluid or solid particle from leaking between adjacent junction plane, and prevents material or part that introduced contaminants is invaded machinery equipment inside as dust and moisture etc.There is at present the RO membrane seal of a kind of use in household water filter, its structure refers to Fig. 1, this structure RO membrane seal comprises ring body 1 and guide ring 2, the lower end of ring body 1 is connected with the upper end of guide ring 2, the sidewall of guide ring 2 is protruding to the direction away from ring body 1 axis, and forms annular groove 21 in the inner side of guide ring 2.Because the transitional surface between guide ring 2 and ring body 1 is inclined-plane, when this structure RO membrane seal is arranged on RO film 4, the former water flowing between guide ring 2 and RO film 4 applies a power to inclined-plane under the effect of pressure, make ring body 1 deform and occur channeling water point to the direction away from RO film 4, thereby cause channeling water phenomenon, reduced the sealing effect of RO membrane seal, make the former water that enters into water purifier through filter assemblies, directly not arrive pure water water outlet, affected the purifying effect of water purifier.
Model utility content
In order to overcome the problems referred to above, the utility model provides a kind of good sealing effect, there will not be the RO film leakage-proof Sealing of channeling water phenomenon to society.
The technical solution of the utility model is: a kind of RO film leakage-proof Sealing is provided, comprise the ring body and the guide ring that are provided with center hole, the lower end of described ring body is connected with the upper end of described guide ring, the sidewall of described guide ring is to the direction projection away from described ring body axis, and form annular groove in the inner side of described guide ring, the lower end of described ring body extends to form annular wall downwards along the direction of axis, and described annular wall is positioned at the inside of described guide ring.
As to improvement of the present utility model, the lower end surface of described annular wall is vertical with the axis of described ring body.
As to improvement of the present utility model, between the lower end surface of described annular wall and the sidewall of described annular wall, be provided with chamfering.
As to improvement of the present utility model, the rear surface of described annular wall is conical surface.
As to improvement of the present utility model, described annular wall funneling.
The utility model is owing to having adopted annular wall, when RO film leakage-proof Sealing is arranged on RO film, the former water flowing between guide ring and RO film applies a power to the sidewall of annular wall under the effect of pressure, thereby annular wall is more closely arranged on the outer surface of RO film, and the lower end surface of annular wall is that conical surface or lower end surface are vertical with axis, the former water that is positioned at like this annular wall lower end just can not make annular wall occur channeling water point, thereby affect the purifying effect of water purifier, there is the advantages such as simple in structure, easy to use and good sealing effect.

Embodiment
In description of the present utility model, it will be appreciated that, in term, orientation or the position relationship of the indication such as " " center ", " on ", D score, 'fornt', 'back', " left side ", " right side " be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; rather than the device of indication or hint indication or element must have specific orientation, with specific orientation structure and operation, so can not be interpreted as restriction of the present utility model.
Refer to Fig. 2 to Fig. 5, what Fig. 2 to Fig. 5 disclosed is a kind of RO film leakage-proof Sealing, comprise the ring body 1 and the guide ring 2 that are provided with center hole, the lower end of described ring body 1 is connected with the upper end of described guide ring 2, the sidewall of described guide ring 2 is to the direction projection away from described ring body 1 axis, and in the inner side of described guide ring 2, form annular groove 21, from guide ring described in sectional view 2 cross section become barb shape.
In the present embodiment, the lower end of described ring body 1 extends to form annular wall 3 downwards along the direction of axis, and described annular wall 3 is positioned at the inside of described guide ring 2.When described ring body 1 is arranged on RO film 4, the former water flowing between described guide ring 2 and described RO film 4 applies a power to the sidewall of described annular wall 3 under the effect of pressure, this power is more closely arranged on the outer surface of described RO film 4 described annular wall 3, make to there will not be channeling water point between described RO film leakage-proof Sealing and described RO film 4, also there will not be channeling water phenomenon.
In in the present embodiment, the sealing contact surface that described annular wall 3 has not only increased described RO film leakage-proof Sealing and described RO film 4 amasss, also overcome the technology prejudice of prior art, the pressure producing in described annular wall 3 by the former water flowing between described guide ring 2 and described RO film 4, described annular wall 3 is more closely arranged on the outer surface of described RO film 4, has improved the sealing effect of described RO film leakage-proof Sealing.
In the present embodiment, the lower end surface of described annular wall 3 is vertical with axis, the lower end surface that is described annular wall 3 is right angle face, and be provided with chamfering between the lower end surface of described annular wall 3 and the sidewall of described annular wall 3, the benefit of design is like this, when former water produces pressure on the lower end surface of described annular wall 3, can not make described annular wall 3 occur channeling water point, make on the contrary described annular wall 3 more closely be arranged on described RO film 4.The lower end surface of described annular wall 3 can also be conical surface, and the benefit of design is like this, has improved the utilization ratio that former water acts on the pressure on described conical surface, utilizes the pressure of former water that annular wall 3 is more closely arranged on described RO film 4.The sidewall thickness of described annular wall 3 is even, all right funneling of described annular wall 3, and the sidewall thickness of described annular wall 3 reduces from top to bottom successively.The utlity model has the advantages such as simple in structure, easy to use and good sealing effect.
