An opening 241 is integrally formed in a side wall of the sealing lid 124, and the opening 241 protrudes from a side wall of the mounting portion 121. The sealing cover 124 seals the notch of the bearing groove 123, so that liquid in the water bag 1 is in a sealed cavity, the probability of liquid scattering due to transportation is reduced, the opening part 241 protrudes out of the side wall of the mounting part 121, the opening part 241 can be pulled by fingers during use, and the water bag 1 is convenient to use.

Referring to fig. 3 and 4, the fixing member 2 includes a base 4 and a cover 5. The top of the base 4 is provided with an installation groove 41 for inserting the water bag 1, and the water bag 1 protrudes out of the notch of the installation groove 41. The cover 5 covers the notch of the mounting groove 41, and one end of the cover 5 close to the base 4 is provided with a yielding groove 51 for inserting the water bag 1. The water bag 1 covers the base 4, so that the water bag 1 is in a sealed cavity, and the probability that the water bag 1 falls off during transportation is reduced.

Referring to fig. 3, a first magnetic block 42 is embedded in one end of the base 4 close to the sealing cover 5, and a second magnetic block 52 opposite to the first magnetic block 42 is embedded in one end of the sealing cover 5 close to the base 4. The first magnetic block 42 and the second magnetic block 52 are mutually attracted, so that the sealing cover 5 is fixed on the base 4, and the probability that the sealing cover 5 falls off during transportation is reduced.

The implementation principle of the water bag 1 component in embodiment 2 of the application is as follows: during transportation, the sealing cover 124 needs to be adhered to the notch of the bearing groove 123 of the water sac 1 to seal the liquid. Subsequently, the water bag 1 is inserted into the mounting groove 41 in the base 4 in an aligning manner, the sealing cover 5 covers the mounting groove 41 in the base 4, the second magnetic block 52 on the sealing cover 5 and the first magnetic block 42 on the base 4 are magnetically attracted with each other, so that the sealing cover 5 is fixed on the base 4, the water bag 1 is fixed, and the risk that the water bag 1 drops due to vibration generated in transportation is reduced.

Example 3:

the application 3 discloses a contactless hand-held ultrasonic knife, refer to fig. 5, and include water bag 1, water bag 1 subassembly and water supply bag 1 install casing 6.
