The cleaning liquid supplied by rotation has a higher cleaning power than the cleaning fluid supplied in one direction, thereby improving cleaning efficiency.

The cleaning liquid and the cleaning gas supplied to the cleaning object can clean the cleaning object. During cleaning, the cleaning liquid and the cleaning gas obtained by first cleaning the object to be cleaned collide with the lower surface of the upper cover 210 and are supplied back to the object to be cleaned, thereby secondary cleaning the object to be cleaned.

Unlike the above-described example, when cleaning the object to be cleaned only with the cleaning gas, the opening/closing unit 350 may clean the object to be cleaned only with the high-pressure cleaning gas supplied from the outside while sealing the upper space and the lower space.

As described above, the ER collet washer according to an embodiment of the present invention can efficiently clean an object to be cleaned during cleaning. In addition, it is possible to maintain the cleanliness of the cleaning fluid by preventing foreign substances from flowing into the cleaning gas or the cleaning liquid.

In addition, the ER collet washer according to an embodiment of the present invention may improve cleaning efficiency by directly supplying a cleaning fluid in which a cleaning liquid and a cleaning gas are mixed to a hollow portion of a hollow shape so that the cleaning fluid comes into contact at the top and bottom. .

In addition, the ER collet washer according to an embodiment of the present invention can be cleaned with a cleaning gas or a fluid in which a cleaning gas and a cleaning liquid are mixed depending on the object to be cleaned, thereby improving cleaning efficiency.

In addition, according to an embodiment of the present invention, the ER collet cleaner may improve the cleaning efficiency of the cleaning object by applying a rotational force when the cleaning fluid is supplied to the cleaning object.

In the above-described example, the size of the support has been described as an example, but unlike this, it may be provided to change the size of the support according to the size of the object to be cleaned.

The detailed description above is illustrative of the present invention. In addition, the above description shows and describes preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications and environments. That is, changes or modifications may be made within the scope of the concept of the invention disclosed in the present specification, the scope equivalent to the disclosed contents, and/or the skill or knowledge of the art.
