Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the present embodiment provides a partition structure of a filter element assembly, which includes a central tube 1, a housing 2 and a reinforcing rib structure.

The shell 2 is sleeved outside the central tube 1, and a water passing cavity is formed between the shell and the central tube 1.

The strengthening rib structure is arranged in the water passing cavity and on the peripheral wall of the central tube 1, the central tube 1 extends out to the shell 2, and the inner peripheral wall of the shell 2, the peripheral wall of the central tube 1 and the strengthening rib structure jointly form a water flowing channel 3.

When the filter element assembly with the partition structure is applied to a water purifier, the shell 2 is used for partitioning a raw water branch and a pure water branch, the central tube 1 is used for partitioning a pure water branch water channel which does not pass through the composite filter element and a pure water branch water channel which passes through the composite filter element, namely, the shell 2 is used for containing raw water, the shell 2 is used for containing pure water which does not pass through the composite filter element in the water flowing channel 3 between the central tube 1, and the central tube 1 is used for containing pure water which passes through the composite filter element. Because the two sides of the shell 2 are respectively provided with the raw water channel and the filtered pure water channel, the water channels at the two sides have great concentration difference, and the pressure difference generated by the concentration difference between the liquids easily causes the two sides of the middle shell 2 to be unbalanced in stress and generate severe deformation. In the embodiment, the reinforcing rib structure is arranged in the water passing cavity and extends from the central pipe 1 to the shell 2, so that on one hand, the stress strength of the outer surface of the central pipe 1 provided with the reinforcing rib structure can be enhanced; on the other hand, locate the strengthening rib structure in the water cavity and can play the effect of supporting casing 2 when casing 2 is because of inside and outside pressure differential atress warp to the 1 side of center tube dent, make the inside and outside both sides atress of casing 2 reach balanced can not produce excessive deformation and break, promptly, when the inner shell dent, the strengthening rib structure can give casing 2 through the mode of supporting and balance too big pressure differential with the holding power, in case the atress of casing 2 is in balanced state, casing 2 will stop deformation, the damaged problem of inner casing wall has just no longer existed. Simultaneously, locate the periphery wall of center tube 1 with the strengthening rib structure on, still have easy machine-shaping's advantage.

Alternatively, the rib structure may be provided on the inner peripheral wall of the housing 2 and extend from the housing 2 to the center tube 1.

In the present embodiment, the rib structure abuts against the inner peripheral wall of the housing 2. This allows the housing 2 to be supported by the stiffener structure when it is initially stressed and deformed with a tendency to bend towards the central tube 1, making the housing 2 less prone to deformation. As an alternative embodiment, the ribs may have a fine pitch with the inner peripheral wall of the housing 2, so that the rib structure can support the housing 2 after the housing 2 is slightly deformed, thereby preventing the housing 2 from being further deformed and broken.

The concrete structural style of the reinforcing rib structure can be various, and in the embodiment, the reinforcing rib structure comprises a plurality of ribs which are distributed on the peripheral wall of the central tube 1 at intervals.

Specifically, the plurality of ribs is configured as a plurality of reinforcing rib groups distributed at intervals in the axial direction of the base pipe 1, and each reinforcing rib group includes at least two ribs distributed at intervals in the circumferential direction of the base pipe 1. Can promote the holistic atress intensity of center tube 1 like this, can support 2 wholly simultaneously to each position that makes casing 2 all is difficult for taking place to warp when receiving the pressure that inside and outside pressure differential brought, makes casing 2 more difficult emergence fracture.

As an alternative embodiment, the plurality of ribs may be randomly distributed on the outer circumferential wall of the center tube 1.

In order to obtain a better supporting effect on the housing 2, in the present embodiment, the respective sets of reinforcing ribs are uniformly distributed along the axial direction of the central tube 1, and the respective ribs in each set of reinforcing ribs are uniformly distributed along the circumferential direction of the central tube 1.

In order to facilitate the processing and forming, in the embodiment, the ribs in each reinforcing rib group are arranged in one-to-one correspondence with the ribs in the adjacent reinforcing rib group. Alternatively, the ribs of each rib group may be staggered with respect to the ribs of the adjacent rib group.

The extending direction of the ribs is not limited, and in this embodiment, the ribs are transverse ribs 4 perpendicular to the axial direction of the center pipe 1. Therefore, the supporting strength of the shell 2 can be ensured, and the advantages of material saving and convenience in molding are also achieved. As an alternative embodiment, the ribs can also be vertical ribs extending in the axial direction of the base pipe 1.

The embodiment also provides a filter element assembly, which comprises the partition structure of the filter element assembly and a filter element arranged in the central tube 1.

The embodiment also provides a water purifier, which comprises the filter element assembly.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications can be made without departing from the scope of the invention.
