According to the water purifying device 10 provided by the scheme, during assembly, the filter element assembly 13 is inserted into the filter element installation cavity 111, then the handle 14 is rotated forward, so that the first matching part 141 and the limiting part 114 are in limit matching to prevent the filter element assembly 13 from being taken out of the filter element installation cavity 111, meanwhile, the locking assembly 12 and the second matching part 1421 are locked together to prevent the handle 14 from rotating reversely, as shown in fig. 2 and 3, and therefore the filter element assembly 13 is reliably located in the machine body 11. When disassembly is required, the locking assembly 12 is adjusted to an unlocked state, then, as shown in fig. 4 and 5, the handle 14 is turned reversely so that the first matching portion 141 is separated from the limiting portion 114, and then the filter element assembly 13 is pulled out from the filter element installation cavity 111. Based on locking Assembly 12 sets up on organism 11 to only when changing filter element group spare 13 handle 14 need follow the replacement, and locking Assembly 12 can remain and continue to use, and then has reduced filter element replacement cost.

Specifically, as shown in fig. 2 to 5, in one embodiment, the filter element assembly 13 is a cylindrical structure, and a rotation axis of the handle 14 rotatably engaged with the filter element assembly 13 is opposite and perpendicular to an axis of the filter element assembly 13.

As shown in fig. 2 and 3, when the locking assembly 12 is locked with the second engaging portion 1421, the handle 14 cannot be reversed relative to the filter element assembly 13, so that the first engaging portion 141 and the limiting portion 114 are always in limiting engagement, the filter element assembly 13 cannot move in the axial direction of the filter element assembly 13 relative to the housing 11, and the filter element assembly 13 is reliably locked in the filter element installation cavity 111.

Under the condition that the limiting part 114 does not exit the abdicating groove 1411, the handle 14 and the filter element assembly 13 cannot exit the filter element installation cavity 111.

As shown in fig. 5, after the handle 14 is turned upside down by a certain angle, the jacking portion 1412 abuts against the second stopper surface 1142. Continuing to reverse the handle 14, the limiting portion 114 provides a force for the jacking portion 1412 to move in a direction away from the bottom wall of the filter element installation cavity 111.

As shown in fig. 2, the power arm M1 is related to the distance between the portion of the middle holding portion 142 pressed down by the operator and the rotation shaft, and the resistance arm M2 is related to the distance between the position of the first position-limiting surface 1141 abutting against the locking portion 1413 and the rotation shaft. The power arm M1 is larger than the resistance arm M2, and can play a role of saving power.

During the process of reversely taking out the filter element assembly 13, the operator still holds the middle holding portion 142 by hand, and the limiting portion 114 gradually exits from the receding groove 1411. After the locking assembly 12 is unlocked from the second mating portion 1421, the handle 14 is automatically reversed by a small angle, and then the operator can continue to reverse the handle 14, and the lifting portion 1412 abuts against the second position-limiting surface 1142. As shown in fig. 5, in the process, the power arm M3 is related to the distance between the part of the middle holding portion 142 provided for the operator to the rotating shaft, and the resistance arm M4 is related to the position of the second position-limiting surface 1142 abutting against the jacking portion 1412 and the distance between the rotating shafts.
