Water purifier and pressure stabilizing pump thereof

Abstract

The invention discloses a water purifier and a pressure stabilizing pump thereof. The pressure stabilizing pump comprises a pump shell and a water outlet pressure plate located below the pump shell. Protruding rings protruding downwards are arranged on the lower side of the pump shell. Grooves are formed in the upper side of the water outlet pressure plate. Sealing rings are arranged in the grooves. Protrusions and first abutting faces capable of abutting against the upper end face of the water outlet pressure plate are arranged at the lower ends of the protruding rings. The protrusions can stretch into the grooves and abut against the upper sides of the sealing rings. The first abutting faces are higher than the lower ends of the protrusions. The depth of the parts, stretching into the grooves, of the protrusions is limited by the first abutting faces, and therefore it is guaranteed that the sealing rings cannot excessively deform, the situation that the elasticity of the sealing rings becomes small is avoided, and it is guaranteed that in the product life cycle, the sealing rings have good elasticity so as to meet the long-term sealing requirement. In addition, the soft contact in the prior art is replaced with hard contact, the positioning of the pump shell in the vertical direction is achieved, and the situation that the pump shell slightly swings in the vertical direction is avoided.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, more specifically, to a water purifier and a pressure stabilizing pump thereof. Background technique [0002] At present, with the improvement of people's living standards and the development of water purification technology, the health of drinking water has become a focus of attention, and more and more water purifiers have entered ordinary families. In the structural design of the water purifier, the pressure stabilizing pump is its key component, such as Figure 1-2 As shown, the structure of the stabilizing pump includes a pump casing 01 and a water outlet pressure plate 04 arranged under the pump casing 01, wherein the lower side of the pump casing 01 is provided with a downwardly protruding convex ring 01a, and the upper side of the water outlet pressure plate 04 There is a groove matching the convex ring, and a sealing ring 02 is arranged in the groove. After the pump ...

Problems solved by technology

Additionally, if Figure 2-4 As shown, the sealing ring 02 has been squeezed for a long time, the material is aging, and the elasticity becomes smaller, which will easily lead to a gap between the convex ring and the groove, and then cause the water in the high pressure chamber to leak into the pipe pressure chamber, causing the outlet water pressure and flow Reduced etc.
