Embodiment 1

[0047] Example 1, as figure 2 , 4, in some embodiments, the support member is the structure of the central tube 5, the central tube 5 is a cylindrical tube with a hollow cavity, and the tube wall is provided with a guide hole running through the inner and outer walls , the guide holes include a first guide hole 61 opposite to the position of the first filter element 1 and a second guide hole 62 opposite to the position of the second filter element 2 , passing through the first filter element 1 The filtered pure water can enter the interior of the central pipe 5 through the first guide hole 61 , and the pure water filtered through the second filter element 2 can enter the center through the second guide hole 62 . Inside of tube 5.

[0048] This is the preferred structural form of Embodiment 1 of the present invention. In the present invention, the support member is preferably arranged as a central tube structure (the whole is an injection molded part), which can effectively s...

Embodiment 3

[0056] Example 3, in some embodiments, the central tube 5 further includes a fourth shaft section 54 and a fifth shaft section 55, and the fifth shaft section 55 is further provided with a third guide hole 63, The segment filter also includes a third filter element, the first filter element 1 is wound around the outer periphery of the first shaft section 51, and the concentrated water filtered by the second filter element 2 can reach the third filter element for filtration, The pure water filtered by the third filter element can also enter the interior of the central pipe and be discharged along the central pipe, and the concentrated water filtered by the third filter element can pass through the concentrated water outlet 4 and be discharged along the central pipe. be discharged. This is the preferred structural form of Embodiment 3 of the present invention, such as Image 6 As shown in the figure, that is, it is set to five shaft sections in the axial direction, and there ar...

Embodiment 2

[0057] Example 2, as image 35. In some embodiments, the support member includes an end cap assembly 9, a first rear filter element 10 and a second rear filter element 11, the interior of the first rear filter element 10 having a first hollow cavity, The second rear filter element 11 has a second hollow cavity inside, the first rear filter element 10 is opposite to the first filter element 1, and the pure water filtered by the first filter element 1 can pass through the first filter element 1. After a rear filter element 10 is further filtered and enters the first hollow cavity, the pure water filtered by the second filter element 2 can be further filtered through the second rear filter element 11 and enter the second intermediate In the hollow cavity, the first hollow cavity communicates with the second hollow cavity. In the present invention, the support member includes an end cap assembly and two rear filter elements, so that the fine filter element can play a stage-type f...

Abstract

The invention provides a stage type filter element and a water purifying device.The stage type filter element comprises a first filter element body, a second filter element body and a supporting component, the supporting component can support the first filter element body and the second filter element body at the same time, raw water can be filtered through the first filter element body, and the second filter element body can be filtered through the second filter element body; pure water filtered by the first filter element can enter the supporting component and is discharged along the supporting component, and concentrated water filtered by the first filter element can reach the second filter element to be filtered; pure water filtered by the second filter element can also enter the supporting component and is discharged along the supporting component, and concentrated water filtered by the second filter element can pass through the concentrated water outlet and is discharged. According to the invention, the stage type filtering technology can be realized, the stage type filter element filtering function on the same central pipe is realized, the volume can be reduced while the recovery rate is improved, and the problem of whole machine volume control caused by series connection of a plurality of filter elements is solved.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a stage-type filter element and a water purification device. Background technique [0002] The core component of the water purifier is the filter element, of which the main purification effect is the fine filter element used. The roll-type diaphragm is rolled on the central tube with the gluing process to realize the single-stage high-precision filtration function. With the development of water purifiers, high water yield has become a development trend of water purifiers in recent years. In order to achieve this trend in the field of household water purification, the existing technical means include adding a chemical anti-scale filter element before the fine filter element to effectively inhibit the scaling trend of divalent ions and improve the water production rate; it also includes using two fine filter elements in series. , the concentrated water of t...
