Through making annular water tank 300 and shell main part 100 detachable connection, compare in annular water tank 300 and shell main part 100 structure as an organic whole for annular water tank 300 detachable makes, then reducible processing cost, and annular water tank 300 can dismantle, and the user of being convenient for more dismantle annular water tank 300 clean, effectively can reduce annular water tank 300's the clean degree of difficulty.

In an embodiment, referring to fig. 1 and fig. 4 to fig. 6 again, the mounting shell 120 is configured in a cylindrical shape, and the handle 110 includes a shank 111 and an arc-shaped section 112 connected between the shank 111 and the mounting shell 120; the shank 111 extends in the up-down direction, and the arc-shaped segment 112 extends in the circumferential direction of the annular tank 300;

the circular water tank 300 penetrates through the arc-shaped section 112, front and rear sides of the circular water tank 300, which are concavely arranged, respectively enclose with front and rear wall surfaces of the arc-shaped section 112 to form the front cavity 320 and the rear cavity 330, and the control board 500 is fixed on the concaved rear side wall of the circular water tank 300 and extends from the rear cavity 330 to the inner cavity of the handle 111; the side walls of the front cavity 320 and the rear cavity 330 in the circumferential direction of the annular water tank 300 are spliced with the two end surfaces of the arc-shaped section 112.

In the present embodiment, specifically, the mounting case 120 is provided in a cylindrical shape such that the above-described air duct 121 is formed inside the cylinder. The handle 110 includes a shank 111 and an arc segment 112, such that the arc segment 112 extends along the circumference of the annular water tank 300, and two end surfaces of the arc segment 112 in the circumference may be in limited abutment with and spliced with the left and right side walls of the front groove 380 and the rear groove 380 of the annular water tank 300. That is, the length of the arc-shaped segment 112 is adapted to the length of the front and rear grooves 380 of the ring-shaped water tank 300, and the arc-shaped segment 112 and the ring-shaped water tank 300 can be combined into a complete circle. In this way, while ensuring that the annular water tank 300 can surround the outer periphery of the entire mounting shell 120, the annular water tank 300 is prevented from rotating in the circumferential direction relative to the mounting shell 120, and the overall consistency of the annular water tank 300 and the handle 110 can be ensured, so that the overall appearance is more complete and attractive.
