Embodiment 1

[0051] Such as Figure 1 to Figure 5As shown, a nozzle sealing structure provided in this embodiment includes: a substrate, on which a nozzle is formed, and a sealing groove 11 and a guide groove 12 formed at the nozzle, the sealing groove 11 and the guide groove 12 are arranged in communication; The water rod 2 is set on the guide groove 12 in a linear reciprocating manner under the action of the driving member 3; the sealing member 4 is arranged on the sealing groove 11; Under the action of the sealing part 21 abuts on the sealing member 4 .

[0052] In the sealing structure of the nozzle in this embodiment, the sealing member 4 is installed in the sealing groove 11. When the water stop rod is reciprocating, the sealing part 21 on it abuts against the sealing member 4 to realize the sealing at the nozzle. This design In this way, the seal 4 will not move together with the water stop rod 2, avoiding the wear of the seal 4, and the same water stop rod 2 is not installed with ...

Embodiment 2

[0065] Such as Figure 6 As shown, a filter element provided in this embodiment includes the nozzle sealing structure described in the above-mentioned embodiment 1, and a filter element body 6, the filter element body 6 is provided with a pure water channel 61, and the central rod 1 is set on the pure water On the water channel 61, the central rod 1 is inserted in the end of the pure water channel near its outlet in an interference fit manner, and a sealing ring structure is installed at the contact between the outer peripheral surface of the central rod 1 and the inner wall of the pure water channel to prevent water leakage .

Embodiment 3

[0067] This embodiment provides a water purification device, specifically a drinking water purifier commonly used in daily life, which includes the filter element in the above-mentioned embodiment 2, and has all its technical advantages, which will not be repeated here.

Abstract

The invention relates to the technical field of water purification equipment, in particular to a water gap sealing structure, a filter element and water purification equipment. The water gap sealing structure comprises a base body, a water gap is formed at the base body, a sealing groove and a guide groove are formed in the base body, the sealing groove and the guide groove are formed in the watergap, and the sealing groove communicates with the guide groove; a water stop rod is arranged on the guide groove in a linear reciprocating motion manner under the action of the driving piece; a sealing part is arranged on the sealing groove; and the sealing part is formed on the water stop rod, and the sealing part abuts against the sealing part under the action of a driving piece. According to the water gap sealing structure disclosed by the invention, the sealing part is mounted in the sealing groove; when the water stop rod moves in the reciprocating mode, the sealing part on the water stop rod abuts against the sealing part to achieve sealing of the water gap, due to the design mode, the sealing part cannot move along with the water stop rod, the abrasion problem of the sealing ring is avoided, meanwhile, the sealing ring is not installed on the water stop rod, the movement resistance of the water stop rod is reduced, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water outlet sealing structure, a filter element and water purification equipment. Background technique [0002] At present, due to the increasingly serious water quality problems and the gradual improvement of people's living standards, water purifiers have gradually become one of the important household appliances in life. In the existing water purifiers, in order to facilitate the user to use and change the filter element, the rotary snap-in filter element has gradually become the mainstream filter element structure. In addition to the convenience of changing the element, the rotary snap-in filter element also needs to simultaneously solve the problem of the waterway card seat and the filter element when changing the element. There is a water sealing problem at the water outlet of the filter element. [0003] The common water sealing structure of the fi...
