Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter elements, in particular to a composite filter element for a water purifier. Background Art
[0002] The filter element of a water purifier generally contains KDF and activated carbon. The filter element purifies contaminated water to the state required for production and life, that is, it makes the water reach a certain degree of cleanliness.
[0003] When the filter element is installed in the filter cartridge, a sealing ring needs to be installed to ensure the sealing between the filter cartridge and the filter cartridge. By installing the sealing ring, water can only flow through the filter element, thereby purifying the water. However, after the current filter element is installed in the filter cartridge, the friction between the sealing ring and the filter cartridge makes it inconvenient to remove the filter element. For this reason, the present application proposes a composite filter element for a water purifier. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a composite filter element for a water purifier.
[0005] The embodiment of the present utility model provides a composite filter element for a water purifier, comprising:
[0006] A filter element body, wherein a short water inlet pipe is installed at the upper end of the filter element body and a short water outlet pipe is installed at the lower end;
[0007] An adjustable filter element sealing assembly; the filter element sealing assembly includes a rubber ring that is sleeved on the filter element body, a V-shaped sealing ring that is fixed on the rubber ring and arranged in an inclined and annular manner, a connecting ring is sleeved on the water inlet short pipe, the connecting ring is connected to the V-shaped sealing ring through two pull ropes, and a tightening ring is installed on the rubber ring.
[0008] Furthermore, the outer wall of the water outlet short pipe is provided with two annular grooves, and rubber sealing rings are installed in the annular grooves.
[0009] Furthermore, the rubber ring and the V-shaped sealing ring are both made of rubber material, and the rubber ring and the V-shaped sealing ring are integrally formed.
[0010] Furthermore, the connecting ring is slidably connected to the outer wall of the water inlet short pipe, and the connecting ring abuts against the upper end of the filter element body.
[0011] Furthermore, the two pull ropes are symmetrically distributed on the connecting ring.
[0012] Furthermore, the tightening ring is sleeved on the outside of the rubber ring so that the rubber ring is pressed against the filter element body.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The utility model can not only ensure the sealing of the filter element after being installed in the filter element barrel, but also facilitate the subsequent removal and replacement of the filter element body, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0020] like Figure 1-Figure 3 As shown, the embodiment of the present utility model provides a composite filter element for a water purifier, comprising:
[0021] The filter element body 1 has a water inlet short pipe 3 installed at the upper end and a water outlet short pipe 2 installed at the lower end. The outer wall of the water outlet short pipe 2 is provided with two annular grooves 9, and a rubber sealing ring 10 is installed in the annular groove 9. When the filter element body 1 is installed, the water outlet short pipe 2 is located in the pipe at the lower end of the filter element barrel. The provision of the rubber sealing ring 10 can make the water outlet short pipe 2 and the pipe at the lower end of the filter element barrel sealed and also realize the limitation of the filter element body 1, so that it is not easy to shake in the filter element barrel.
[0022] An adjustable filter element sealing assembly; the filter element sealing assembly includes a rubber ring 6 that is sleeved on the filter element body 1, and a V-shaped sealing ring 7 that is tilted and annularly arranged is fixed on the rubber ring 6. The rubber ring 6 and the V-shaped sealing ring 7 are both made of rubber, and the rubber ring 6 and the V-shaped sealing ring 7 are integrally formed. A connecting ring 8 is sleeved on the water inlet short pipe 3, and the connecting ring 8 is slidingly connected to the outer wall of the water inlet short pipe 3. The connecting ring 8 is against the upper end of the filter element body 1, and the connecting ring 8 is connected to the V-shaped sealing ring 7 through two pull ropes 5. The two pull ropes 5 are symmetrically distributed on the connecting ring 8. A tightening ring 4 is installed on the rubber ring 6, and the tightening ring 4 is sleeved on the outside of the rubber ring 6 to make the rubber ring 6 against the filter element body 1, so that the rubber ring 6 and the V-shaped sealing ring 7 can be fixed on the filter element body 1.
[0023] During installation, the filter element body 1 is installed in the filter element barrel. At this time, the V-shaped sealing ring 7 is against the inner wall of the filter element barrel. Due to the limit of the filter element barrel, the V-shaped sealing ring 7 is retracted, and the filter element body 1 and the filter element barrel can be sealed by the V-shaped sealing ring 7. When water enters the filter element barrel, some water will enter the V-shaped sealing ring 7. Since the rubber ring 6 is tightened by the tightening ring 4, the rubber ring 6 and the filter element body 1 are sealed. The clean water will remain in the V-shaped sealing ring 7 and cause it to expand to a certain extent, thereby improving the sealing effect between the V-shaped sealing ring 7 and the filter element barrel.
[0024] When the filter element body 1 needs to be removed, the staff can pull the connecting ring 8 by hand. The movement of the connecting ring 8 drives the pull rope 5 to move. The movement of the pull rope 5 causes the connection between the V-shaped sealing ring 7 and the pull rope 5 to deform. This deformation radiates to the part of the V-shaped sealing ring 7 close to the filter element barrel, so that the V-shaped sealing ring 7 is deformed and the filter element body 1 can be removed by pulling it, which greatly reduces the difficulty of removing the filter element body 1.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
