The pair of net parts 51 and 52 may include a first net part 51 disposed in the first washing space 10a and a second net part 52 disposed in the second washing space 10b. there is. One of a left eye contact lens and a right eye contact lens may be placed on the first mesh portion 51 , and the other of the left eye contact lens and the right eye contact lens may be placed on the second mesh portion 52 .

The grip part 53 may be formed by bending the metal wire so as to be convex upward. The grip part 53 may form a coupling groove 53a into which the upper end of the trellis holder 13c is inserted and coupled. That is, the yard chae 50 is formed by the holding part 53 and may include a coupling groove 53a into which the upper end of the yard chae holder 13c is inserted and coupled.

When the holding part 53 is pressed downward and the upper end of the yard chae holder part 13c is inserted into the coupling groove 53a, the yard chae 50 is the first and second net parts 51 and 52 all first and second. It may be mounted on the partition partition wall 13 (eg, the yard holder 13c) so as to be spaced apart from the pulsator 60 .

The pulsator 60 may be disposed in the washing space to stir the washing solution accommodated in the washing space. The pulsator 60 may be rotatably coupled to the bottom surface of the washing space. The pulsator 60 may include a plurality of pulsators. The plurality of pulsators may include a first pulsator 61 disposed in the first washing space 10a and a second pulsator 62 disposed in the second washing space 10b.

The pulsator 60 may include blades 61a and 62a and rotating shafts 61b and 62b. The blade may be fixed to the upper end of the rotating shaft and rotated together with the rotating shaft. The blades 61a and the rotation shaft 61b of the first pulsator may be referred to as the first blade and the first rotation shaft, respectively, and the blade 62a and the rotation shaft 62b of the second pulsator are the second blade and the second blade, respectively. 2 It can be referred to as the axis of rotation.

The blades 61a and 62a may be disposed in the washing space, and the rotation shafts 61 and 62b may be rotatably coupled through the bottom surface of the washing space (or the bottom surface of the washing space forming unit). The first rotating shaft may pass through the first washing space forming part, and the second rotating shaft may pass through the second washing space forming part. The lower ends of the first and second rotation shafts may be exposed to the gear space.

The gear train 40 may be disposed in the gear space 10c. Gear train 40 may be coupled to the pulsator 60 (eg, rotating shafts 61b and 62b) and transmit power to the pulsator 60 to rotate the pulsator. Gear train 40 When this is driven, the first and second pulsators 61 and 62 may be rotated.

The gear train 40 may include a plurality of gears. The plurality of gears may include a driving gear 41 and a driven gear 42 . The driven gear 42 may include a plurality of driven gears. The driving gear 41 may drive the gear train 40 by transmitting the rotational force formed by the user to the driven gear 42 .

The first pulsator 61 and the second pulsator 62 may be rotated by being coupled to the gears 41 and 42 of the gear train 40 .

For example, the first rotational shaft of the first pulsator 61 may be connected to the rotational shaft of the driving gear 41 and rotated together with the driving gear 41, and the second rotational shaft of the second pulsator 62 is It may be connected to the rotation shaft of the driven gear 42 , which is rotated by receiving rotational force directly or indirectly from the driving gear 41 , and rotated together with the driven gear 42 . However, it is not limited thereto, and the first rotational shaft of the first pulsator is connected to the rotational shaft of the first driven gear which is rotated by receiving rotational force directly or indirectly from the driving gear and can be rotated together with the first driven gear, The second rotation shaft of the second pulsator may be connected to the rotation shaft of the second driven gear which is rotated by receiving rotational force from the driving gear and/or the first driven gear and rotated together with the second driven gear.

A part of the driving gear 41 may be exposed to the outside of the housing through the slit 11a of the housing. Some of the plurality of teeth of the driving gear 41 may be exposed to the outside of the housing through the slit 11a of the housing.

A user may apply a rotational force to this portion by gripping a portion of the driving gear 41 exposed to the outside of the housing 10, and as the driving gear 41 is rotated by the rotational force applied by the user, the gear train 40 is can be driven

The user can immerse the contact lens in the cleaning solution contained in the washing space by mounting the tteulchae on the tteulchae holder 13c in a state in which the contact lens is seated on the tteulchae 50 . In this state, the user can operate the pulsator by rotating the drive gear. The user can remove dust and/or foreign substances from the contact lenses by using the water flow formed in the cleaning solution inside the cleaning space by the pulsator. When cleaning is complete, the user can easily remove the contact lens from the cleaning solution by holding the gripper and lifting the net. In the process of cleaning the contact lens, since the jigchae separates the contact lens from the pulsator, it is possible to prevent the contact lens from being damaged by the rotating pulsator.

When the washing solution in the washing space is insufficient, the user may replenish the washing solution in the washing space by using the washing solution tube (T) accommodated in the receiving unit.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that it can be done.
