Pressure tank and water purifier with the pressure tank

Abstract

The invention discloses a pressure barrel and a water purifier with the same. The pressure barrel comprises a barrel, a diaphragm and a press ring, wherein the barrel is provided with an inner cavity, the peripheral wall of the inner cavity is provided with annular bosses raised to the inner part of the inner cavity, the diaphragm is provided with a first sealing part located all around the pressure barrel and the press ring is pressed on the first sealing part of the diaphragm so that the first sealing part is hermetically matched with the boss; the surface of the first sealing part which is in contact with the boss is provided with an annular first bulge matched with the surface of the boss so as to form a linear sealing structure. According to the pressure barrel and the water purifier with the same provided by the invention, the surface of the first sealing part of the pressure barrel diaphragm which is in contact with the bulge is provided with the annular first bulge matched with the surface of the boss to form the linear sealing structure, and air leakage points between the diaphragm and the barrel can be eliminated, therefore the reliable sealing between a water storage cavity and a pressure maintaining cavity can be realized.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a pressure tank and a water purifier with the pressure tank. Background technique [0002] The pressure tank is a key component of the water purifier system. Its function is to store the water that has been treated by the purification system, and reserve enough clean water with sufficient water pressure for the user, so that the user can turn on the switch at any time to drink clean water and ensure clean water. The comfort and convenience of using the whole water machine. [0003] Such as figure 1 As shown, the internal structure of the existing pressure tank is composed of three layers of rubber diaphragm 40, PP lining 20 and cylinder body 10 from inside to outside, wherein, rubber diaphragm 40-PP lining 20 is a water storage layer, and rubber diaphragm 40-PP lining 20 is a water storage layer, and the rubber diaphragm 40—the inner wall of the bottom of the cylinder body 10 is ...

AI Technical Summary

Problems solved by technology

When the steel ring has deformation, poor welding defects, coordination displacement between the three layers, and surface defects, the gaps between the layers will not be completely sealed, which will eventually lead to the failure of the water storage layer and the pressure-preserving layer. The seal fails, which in turn causes internal water leakage in the pressure tank, causing the water purifier to fail due to insufficient water pressure inside the pressure tank, affecting the normal use of the user
