Referring to fig. 4, in an embodiment, the anti-dropping portion 120 includes an extending portion 121 and a clamping portion 122, the extending portion 121 is close to the electrode plate 200 relative to the clamping portion 122, and the thickness of the anti-dropping portion 120 decreases from the extending portion 121 to the clamping portion 122, so that the flexible casing 100 can expand uniformly when inflated, so that the treatment region (the region where the electrode plate 200 is located) of the treatment head 10 forms a cylinder with a uniform outer diameter to be attached to the surface of the cavity; if the retaining portion 120 is too thick, the flexible cover 100 near one end (first end 101) of the retaining portion is prevented from expanding to form an inverted conical column. Referring to fig. 4, in an embodiment, the thickness of the first end 101 of the flexible housing 100 increases from the clamping portion 122 to the first end 101, so that the first end 101 maintains its original shape when inflated, and does not deform, so as to prevent the mounting member 500 from coming out of the port 100 b.

To facilitate deformation of the flexible cover 100, in one embodiment, the thickness of the clamping portion 122 may be the same as the thickness of the bellows 110. Referring to fig. 4, in one embodiment, the thickness of the flexible casing 100 provided with the electrode sheet 200 is uniform, so as to further inflate the flexible casing 100 uniformly.

Referring to fig. 5 to 6, the extension cylinder 510 is cylindrical, may be square-cylindrical, and may be specifically provided according to the shape of the port 100 b. The extension cylinder 510 may extend along the direction of the second end 102 of the flexible housing 100, one end of the extension cylinder 510 extends into the inflation cavity 100a, and the other end protrudes from the port 100b of the flexible housing 100, so that the extension cylinder 510 is connected to the mounting seat 400 to mount the flexible housing 100 on the mounting seat 400. Referring to fig. 5, the extension cylinder 510 extends along the inner wall surface of the flexible casing 100, and the flexible casing 100 clamps the extension cylinder 510 for positioning.

Meanwhile, each user can use one treatment head 10 independently, namely a plurality of treatment heads 10 can use the same handle 20, and each treatment head 10 is not required to be provided with one handle 20, so that the treatment cost of the user is saved, and the handle 20 is prevented from being idle.

With continued reference to fig. 1, in one embodiment, the mounting base 400 is snap-fitted to the handle 20. Through mount pad 400 and handle 20 joint, can get up being connected of mount pad 400 and handle 20 high-efficiently fast, easy operation is convenient, the user's of being convenient for equipment operation.

Further, referring to fig. 1 and fig. 2, in an embodiment, one of the mounting seat 400 and the handle 20 is provided with a locking block 402, and the other is provided with a locking groove 20b, and the mounting seat 400 is connected to the handle 20 by locking the locking block 402 in the locking groove 20 b.

Referring to fig. 1 to fig. 2, in an embodiment, a fixture block 402 is disposed on an outer wall of the mounting seat 400, and a clamping groove 20b is disposed on the handle 20. The handle 20 is provided with a mounting groove 20a, the mounting groove 20a is used for accommodating the mounting seat 400, a slot 20b is arranged on a slot wall of the mounting groove 20a, and the flexible casing 100 is connected with the handle 20 through the matching of the latch 402 and the slot 20 b.

In order to facilitate the operation of the user, referring to fig. 1, in an embodiment, the card slot 20b includes a passage slot 20c into which the card 402 extends and a holding slot 20d extending along the circumference of the handle 20, and the passage slot 20c is communicated with the holding slot 20 d.

Referring to fig. 1 to 2, the latch 402 enters the slot 20b through the channel 20c, the mounting seat 400 is rotated, so that the latch 402 moves in the retaining groove 20d, and the retaining groove 20d retains the latch 402 to prevent the latch from being separated from the retaining groove 20d, and the flexible housing 100 is mounted on the mounting seat 400, thereby achieving the connection between the flexible housing 100 and the handle 20. The flexible housing 100 is removed in a manner opposite to the above, the flexible housing 100 is rotated, the latch 402 of the mounting seat 400 moves in the latching groove 20d, and exits the latching groove 20b through the passage groove 20c, so that the flexible housing 100 can be quickly separated from the handle 20. Referring to fig. 1, the structure of the engaging groove 20b not only facilitates the assembly and disassembly of the flexible housing 100 and the handle 20, but also improves the stability of the connection between the flexible housing 100 and the handle 20.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
