Description

Composite filter element

Technical Field

The utility model relates to a composite filter element belongs to the water purification trade.

Background

The RO water purification principle is also called as RO reverse osmosis principle, RO reverse osmosis is a pure water machine (also called as terminal water purification equipment) which can be directly drunk by human without adding any compound after filtering raw water (physical method) by the current international popular methods such as reverse osmosis, so the current RO water purifier has been purchased by more and more consumers, but the volume of the current RO water purifier is larger, and occupies larger space for people living in cities, the front-arranged filter element and the rear-arranged scale inhibition filter element of the water purifier are both composed of two separated filter element components, the volume of the machine is larger, and occupies more space, so that the installation position in the home of the consumer cannot install the water purifier.

Disclosure of Invention

In order to solve the technical problem, an object of the utility model is to provide a composite filter element.

The utility model discloses a following technical scheme realizes:

the utility model provides a composite filter element, includes the casing, set up inhalant canal on the casing, the outlet pipe in the casing, outlet pipe periphery cover is equipped with the annular piece of being made by the filter media, form the water course between the periphery wall of annular piece internal perisporium and outlet pipe, be provided with the water inlet of UNICOM water course and outlet pipe inside on the outlet pipe, be provided with the anti-scaling filter core in the outlet pipe.

The embodiment of the utility model provides an in, be located the end of intaking of anti-scaling filter core and respectively be provided with the PP cotton in the play water end of play water end.

In the embodiment of the utility model provides an in, the water inlet sets up the lower extreme at the play water end.

In the embodiment of the utility model, be provided with the check valve on the inhalant canal.

The embodiment of the utility model provides an in, the outlet pipe is pegged graft in the casing from bottom to top, the lower extreme of outlet pipe is provided with the lug, be provided with on the casing with vertical recess of lug matched with, horizontal recess.

The utility model discloses a composite filter element has following beneficial effect: the composite filter element can greatly reduce the volume of a machine, the service life of the whole filter element is long, the service life of the rear scale inhibition filter element is short, and when the respective service life is reached, the composite filter element can be independently disassembled and replaced, so that the utilization rate of the filter element can be fully utilized, and the maximum service life of the filter element is reached.

Drawings

In order to more clearly illustrate the technical solution of the present invention, the drawings needed for the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is an exploded view of the present invention.

Fig. 2 is a cross-sectional view of the present invention.

Fig. 3 is a schematic view of the housing of the present invention.

Fig. 4 is a schematic view of the outlet pipe of the present invention.

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.

Referring to the attached drawings of the specification, the composite filter element comprises a shell 10, wherein a water inlet channel 11 is arranged on the shell, a water outlet pipe 20 is arranged in the shell, a ring-shaped block 30 made of a filter material is sleeved on the periphery of the water outlet pipe, a water passing channel 12 is formed between the inner peripheral wall of the ring-shaped block and the outer peripheral wall of the water outlet pipe, a water inlet 21 communicated with the water passing channel and the interior of the water outlet pipe is arranged on the water outlet pipe, a scale inhibiting filter element 40 is arranged in the water outlet pipe, and in one embodiment, the ring.

In one embodiment, the water inlet end and the water outlet end of the scale inhibition filter element are respectively provided with PP cotton 50, so that water filtered by the annular block passes through the PP cotton, the scale inhibition filter element and the PP cotton in sequence to perform scale inhibition water outlet, and the scale inhibition water is discharged from the water outlet at the upper end of the water outlet pipe.

In order to ensure that the structure is more reasonable and water can be fully subjected to scale inhibition treatment, the water inlet is arranged at the lower end of the water outlet end.

Furthermore, a check valve 60 is disposed on the water inlet passage.

In a preferred embodiment of the present invention, the outlet pipe is inserted into the housing from bottom to top, the lower end of the outlet pipe is provided with a lug 22, and the housing is provided with a vertical groove 13 and a horizontal groove 14 which are matched with the lug. When the utility model is installed, the lug is aligned with the vertical groove, the water outlet pipe is inserted into the shell, and then the water outlet pipe is rotated to enable the lug to be connected with the horizontal groove, so that the water outlet pipe and the shell can not be separated; when the filter element is required to be detached, the water outlet pipe is rotated, the lug is aligned with the vertical groove, the water outlet pipe is pulled out from the shell, and then the two filter elements can be detached, so that the filter element is convenient to replace.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
