[0026] The inner shaft 8, the middle sleeve 7, and the outer sleeve 6 all extend into the inner cavity of the box body 1, and the inner shaft, the middle sleeve, and the outer sleeve are coaxially arranged, the middle sleeve 7 is inserted into the tube cavity of the outer sleeve 6 in a movable manner, the inner shaft 8 is inserted into the tube cavity of the middle sleeve 7 in a movable manner, and the inner shaft 8 is connected to the outer sleeve 6 through a same-direction transmission gear set 13, so that the inner shaft 8 and the outer sleeve 6 can rotate synchronously in the same direction, and the middle sleeve 7 is connected to the outer sleeve 6 through a reverse transmission gear 10, so that the middle sleeve 7 and the outer sleeve 6 can rotate synchronously in the opposite direction;

[0027] The lens tray 4 is fixed to the lower end of the middle sleeve 7. The lens tray 4 is provided with two lens receiving grooves 41 which are connected vertically. Each lens receiving groove 41 is provided with a lens clamp 42 for clamping a lens.

[0028] The lower brush plate 5 is fixed to the lower end of the inner shaft 8, and the upper plate surface of the lower brush plate 5 is provided with soft bristles 51 for brushing the lower surface of the lens clamped by the lens clamp, and the lower plate surface of the lower brush plate 5 is provided with blades 52 for stirring the cleaning liquid stored in the inner cavity of the box body;

[0029] The upper brush plate 3 is locked at the lower end of the outer sleeve 6 by a locking member 9, and after the locking member 9 is released, the upper brush plate 3 can slide up and down along the outer sleeve 6, and the lower plate surface of the upper brush plate 3 is provided with soft bristles 31 for brushing the upper surface of the lens clamped by the lens clamp, and the upper plate surface of the upper brush plate 3 is provided with blades 32 for stirring the cleaning liquid stored in the inner cavity of the box body;

[0030] A pull rope 11 is wound around the upper part of the outer sleeve 6 for pulling the outer sleeve to rotate, and a return torsion spring (not shown in the figure) is provided on the box cover 2 for driving the outer sleeve to return to its original position;

[0031] The box cover 2 is provided with a rope hole, the free end of the pull rope 11 is passed through the rope hole on the box cover to the outside of the box cover, and a pull ring 12 is fixed to the free end of the pull rope.

[0032] In the embodiment of the present invention, the lens clamp adopts an elastic soft rubber strip attached to the lens receiving groove. In other embodiments of the present invention, the lens clamp may also adopt other components capable of clamping the lens, such as semi-circular claws.

[0033] The embodiment of the present invention is used to clean hard corneal contact lenses, and the method of use is as follows:

[0034] Remove the box cover from the box body, and fill the box body with cleaning liquid or water, and release the lock of the locking piece 9 on the upper brush plate 3, then move the upper brush plate 3 up along the outer sleeve 6 for a distance (to facilitate the placement of the lens on the lens plate), and then put the lens to be cleaned (hard corneal contact lens) into the lens receiving groove on the lens plate, fix it with the lens clamp in the lens receiving groove, and then move the upper brush plate 3 down to the lower end of the outer sleeve 6, and re-lock the upper brush plate 3 with the locking piece 9, at this time, the soft bristles on the lower brush plate 5 and the upper brush plate 3 all touch the lens clamped by the lens clamp;

[0035] Then, the box cover is reassembled onto the box body, and the pull ring 12 is pulled again, and the pull rope 11 then pulls the outer sleeve 6 to rotate. Through the transmission of the same-direction transmission gear set 13 and the reverse transmission gear 10, the inner shaft 8 and the outer sleeve 6 rotate synchronously in the same direction, and the middle sleeve 7 and the outer sleeve 6 rotate synchronously in the opposite direction, so that the lower brush plate 5 and the upper brush plate 3 also rotate synchronously in the same direction, and the mirror plate 4 rotates synchronously in the opposite direction. The soft bristles on the lower brush plate 5 and the upper brush plate 3 immediately clean the upper and lower sides of the lens clamped by the lens clamp. After the pull ring 12 is released, the outer sleeve 6 rotates again driven by the return torsion spring, and the pull rope 11 is also wound back onto the outer sleeve 6. In this process, the soft bristles on the lower brush plate 5 and the upper brush plate 3 will also clean the upper and lower sides of the lens clamped by the lens clamp. The pull ring 12 is pulled back and forth, and the pull ring 12 is released, so that the lens can be cleaned reciprocally.

[0036] After cleaning, the box cover is removed from the box body, the lock of the locking member 9 on the upper brush plate 3 is released, and the upper brush plate 3 is moved up along the outer sleeve 6 for a distance, and then the cleaned lens can be removed from the lens plate.
