Abstract
The utility model discloses a filter core, which comprises a housin, the casing includes body and bottom, be provided with raw water inlet on the body, pure water delivery port and waste water delivery port, be provided with reverse osmosis membrane in the casing, be provided with the switching cover between reverse osmosis membrane and the body, it crosses the mouth of a river and the mouth of a river is crossed to be provided with the pure water on the switching cover, through adhesive tape or glue fixed connection between switching cover and the reverse osmosis membrane, the utility model discloses a design of above-mentioned structure has avoided the use of waterstop to reduce the external diameter of casing, reduced the risk of crossing simultaneously.
Description
Technical Field
The utility model relates to a filter element.
Background
At present, the filter element in the prior art achieves a sealing effect by arranging the water stop belt between the adapter sleeve and the reverse osmosis membrane, and prevents the mixing of raw water and waste water. Because the setting of waterstop can increase the external diameter of filter core casing to make the filter core occupy bigger space, need more materials in the preparation, be unfavorable for practicing thrift the cost. Meanwhile, the water stop is a rubber product, so that the problem of water cross can be caused under the condition that the water stop is installed infirm or reversely.
Disclosure of Invention
In order to solve the technical problem, an object of the utility model is to provide a filter core specifically is directly sealed the sticking fixed connection through adhesive tape or glue between switching cover and the reverse osmosis membrane, makes the two become an organic whole.
The utility model discloses a following technical scheme realizes:
the utility model provides a filter core, includes the casing, the casing includes body and bottom, be provided with raw water inlet, pure water delivery port and waste water delivery port on the body, be provided with reverse osmosis membrane in the casing, be provided with the switching cover between reverse osmosis membrane and the body, it crosses the mouth of a river and the mouth of a river is crossed to be provided with the pure water on the switching cover, pass through adhesive tape or glue fixed connection between switching cover and the reverse osmosis membrane.
The embodiment of the utility model provides an in, be provided with first sealing washer between switching cover and the body, be provided with the second sealing washer between switching cover and the reverse osmosis membrane.
The utility model discloses a filter core has following beneficial effect:
the water stop is not used, the switching sleeve and the reverse osmosis membrane are fixedly connected in a sealing mode through the adhesive tape or the glue, the switching sleeve and the reverse osmosis membrane are integrated, the whole volume of the filter element is reduced, materials are saved, and the problem of water leakage is avoided.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
With reference to the figures of the specification, a filter cartridge comprises a casing (10), the casing (10) comprising a body (20) and a bottom cover (30), the body (20) is provided with a raw water inlet (21), a pure water outlet (22) and a waste water outlet (23), a reverse osmosis membrane (40) is arranged in the shell (10), a switching sleeve (50) is arranged between the reverse osmosis membrane (40) and the body (20), the adapter sleeve (50) is provided with a pure water passing port (51) and a waste water passing port (52), the adapter sleeve (50) is fixedly connected with the reverse osmosis membrane (40) through the adhesive tape or the glue, the adapter sleeve (50) is fixedly connected with the reverse osmosis membrane (40) in a sealing way through the adhesive tape or the glue, so that the adapter sleeve and the reverse osmosis membrane are integrated, the sealing performance is ensured, and meanwhile, the use of a water stop is avoided, so that the problem of water leakage caused by improper operation is avoided. Meanwhile, the diameter of the filter element is reduced without using a water stop, so that the compression size of the filter element is reduced, manufacturing materials are saved, and the cost is reduced.
Further, be provided with first sealing washer (61) between switching cover (50) and body (10), be provided with second sealing washer (62) between switching cover (50) and reverse osmosis membrane (40), more specifically, first sealing washer (61) set up on water mouth (52) is crossed to pure water (51) and waste water. The second sealing ring (62) is arranged on a water outlet nozzle on the reverse osmosis membrane (40).
In the production process, an operator only needs to attach sufficient glue or adhesive tape to the outer wall of the reverse osmosis membrane (40) or the inner wall of the adapter sleeve (50), and then assembly connection is carried out, so that the water stop is not required to be installed, and the complicated procedure of distinguishing the installation direction of the water stop is avoided.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
