Description

Technical Field

[0001] The utility model relates to a filter element, in particular to an upper and lower butt-jointed filter element structure. Background Art

[0002] A longer filter element is required for water purifiers larger than 10 inches. The defects and shortcomings of this type of filter element currently available on the market are mainly: 1. The filter element is too long as a whole, and its main carbon rod is easy to break and be scrapped during handling and transportation; 2. After the granular activated carbon filter element is used, carbon ash is easy to accumulate at the water outlet of the filter element, resulting in very small water flow or even water blockage. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a filter element structure with upper and lower butt joints in view of the deficiencies of the prior art.

[0004] In order to achieve the above purpose, the measures taken by the utility model are:

[0005] A top-bottom butted filter element structure, comprising a first filter element and a second filter element, wherein the first filter element and the second filter element are plug-connected together, a plug connector is provided on a first end cover of the first filter element close to one end of the second filter element, a plug hole is provided on a second end cover of the second filter element close to one end of the first filter element, the plug connector is plugged into the plug hole to realize the plug-connection of the first filter element and the second filter element together, a water outlet external connection hole is provided on a third end cover of the first filter element away from one end of the second filter element, and a water inlet external connection hole is provided on a fourth end cover of the second filter element away from one end of the first filter element;

[0006] The outer wall of the plug connector is provided with a plurality of sealing grooves along the circumferential direction, and the plurality of sealing grooves are each sleeved with a sealing ring;

[0007] After the plug connector is plugged into the plug hole, the cover surfaces of the first end cover and the second end cover are tightly attached together.

[0008] The beneficial effects of the utility model are as follows: the structure is novel, which avoids the accumulation of filter carbon at the water outlet end and the small water flow in large water purifiers, improves the quality of the product, and avoids the breakage of the filter element carbon rod during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the external structure of the utility model.

[0010] Figure 2 It is a schematic diagram of the exploded structure of the utility model. Implementation

[0011] A filter element structure for connecting up and down, comprising a first filter element 1 and a second filter element 2, wherein the first filter element 1 and the second filter element 2 are plug-connected together, a plug connector 301 is provided on a first end cover 3 of the first filter element 1 close to the second filter element 2, a plug hole 401 is provided on a second end cover 4 of the second filter element 2 close to the first filter element 1, the plug connector 301 is plugged into the plug hole 401 to realize the plug-connection of the first filter element 1 and the second filter element 2 together, a water outlet external connection hole 901 is provided on a third end cover 9 at an end of the first filter element 1 away from the second filter element 2, and a water inlet external connection hole is provided on a fourth end cover 8 at an end of the second filter element 2 away from the first filter element 1.

[0012] The first filter element 1 and the second filter element 2 are of equal design. The plug connector 301 and the plug hole 401 are both arranged at the center of the filter element.

[0013] When installed on the pipeline, external water flows into the second filter element 2 from the water inlet external connection hole, then flows into the first filter element 1 from the second filter element 2 through the plug hole 401 and the plug connector 301, and then flows out from the water outlet external connection hole 901 to obtain filtered water.

[0014] like Figure 1 and Figure 2 As shown, the filter element of the present application is particularly suitable for use in water purifiers larger than 10 inches. The entire filter element adopts a structure of upper and lower docking, which reduces the length of a single filter carbon rod in the filter element without affecting the filtering effect, avoiding the risk of carbon rod breakage and scrapping during handling and transportation. In addition, it also avoids the accumulation of carbon ash at the water outlet and the small water flow. The quality and quality of the filter element product are improved.

[0015] A plurality of sealing grooves are formed on the outer wall of the plug connector 301 along the circumferential direction, and sealing rings are sleeved in the plurality of sealing grooves.

[0016] Good sealing effect.

[0017] After the plug connector 301 is plugged into the plug hole 401, the cover surfaces of the first end cover 3 and the second end cover 4 are closely attached to each other, thereby improving the support and preventing the plug connector 301 from breaking or shaking.

[0018] In addition to being connected to the plug connector 301, the plug hole 401 also functions as a diversion hole, which guides the water in the second filter element 2 to the first filter element 1 through the plug hole 401 and the plug connector 301. The plug hole 401 connects the inside and outside of the second filter element 2, and the plug connector 301 is provided with a water flow hole connecting the inside and outside of the first filter element 1 along the axial direction.

[0019] In addition, the present application scheme can be more filter elements, which can be connected in series according to the present application structure to meet the needs of longer filter elements, such as 30 inches, 40 inches, etc. It can be extended indefinitely.
