Traction blocks are rotationally connected to the two ends of the interior of the upper cover part, and one ends of the traction blocks on the two sides are buckled with the locking blocks on the two sides; when force is applied to enable the handle assembly to be in linkage with the upper cover piece to move upwards, the upwards-moving upper cover piece pulls the traction blocks on the two sides to drive the two locking blocks to retract into the cover base body through the locking openings. The elastic component has elastic potential energy; when the force applied to the handle assembly is cancelled, the elastic assembly releases elastic potential energy, and the locking blocks on the two sides extend out of the cover base body; by providing the lifting control locking structure, the upper cover piece can be lifted in a linkage manner when force is applied to the lifting handle assembly for extraction, so that the movable action of the locking blocks on the two sides is realized, and the application of unlocking a filter element structure in a filter element assembling system applying the lifting control locking structure is met.

Description

TECHNICAL FIELD

[0001] The utility model relates to filter core installation technical field, concretely relates to a lock joint structure and filter core system of lifting control. BACKGROUND

[0002] The water purifying device generally includes a filter core assembly and a body, the filter core assembly is installed in the body and is butted with a water circuit board, so that the filter core assembly can normally implement a filtering function. The filtering capacity of the filter core assembly will decrease with the increase of use time, so it needs to be replaced after being used for a period of time. Based on this, the filter core assembly and the body are generally detachably connected.
