Referring toFIG. 4 , the two throughholes 65 have different shapes, respectively. One of the two throughholes 65 is configured to have a circular cross section, and the other one of the two throughholes 65 is configured to have a square cross section. In some examples, thesupport 60 can also serve as a section of themain housing 10, or is machined together with themain housing 10 to be integrally formed, and thesupport 60 can be used for defining theliquid storage cavity 12. - The first
air guiding element 80 is substantially in a circular column shape, and is assembled in the throughhole 65 with the circular cross section, so as to define a gap between the firstair guiding element 80 and the inner wall of the throughhole 65 to form the corresponding first air channel for the air to enter theliquid storage cavity 12. - The second
