[0029] The negative ion generator 3 is fixedly installed on the outer side of the inner liner 1, and at least part of the negative ion generating end 31 is located in the hot air channel 21. During operation, it can generate negative ions, release them into the surrounding air, purify the air and play a role in sterilizing and removing odors.

[0030] Refer to Figure 2 、 Figure 5 As shown in the figure, a ring convex portion 12 is fixedly connected to the outer side of the inner liner 1, and the ring convex portion 12 is integrally formed with the inner liner 1. The ring convex portion 12 is located outside the hot air holes 11, and a plurality of hot air holes 11 are formed in the ring convex portion 12. The plurality of hot air holes 11 are arranged side by side to form a sieve-like structure. The air outlet 22 is adapted to the contour of the ring convex portion 12, and the ring convex portion 12 is sleeved with the air outlet 22 and sealed by a seal 221.

[0031] Furthermore, part of the hot air holes 11 are located at the lower side position of the inner circumference of the ring convex portion 12 and communicate with the lower side wall position of the ring convex portion 12. Through the lower side hot air holes 11, the water in the ring convex portion 12 can flow out, avoiding water accumulation in the ring convex portion 12 and the hot air module 2.
