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.
