The washing apparatus 300 washes the waste water generated from the washing of the workpiece to be washed and delivers the waste water into the tub 100. Specifically, the water collecting shell 1 is provided with a water receiving tank 11 and a water outlet 12 communicated with the water receiving tank 11, waste water generated by cleaning a piece to be cleaned is collected through the water receiving tank 11, the situation that the environment is dirty and messy due to random splashing of the water is avoided, and water in the water receiving tank 11 can be guided into the water tank basin 100 through the water outlet 12.

Optionally, referring to fig. 2, a third sealing ring 73 is provided between the water collecting housing 1 and the locking nut 30, so that water in the water receiving tank 11 is prevented from leaking between the water collecting housing 1 and the locking nut 30.

It is to be understood that the above examples of the present utility model are provided for clarity of illustration only and are not limiting of the embodiments of the present utility model. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the utility model are desired to be protected by the following claims.
