In an embodiment, fig. 4 is a schematic top view of a base according to an exemplary embodiment; fig. 5 is a schematic cross-sectional view of a seat along the direction B-B according to an exemplary embodiment. As shown in fig. 4 and 5, the second fastening portion 21 is an annular boss 202 located on the inner wall of the tubular main body 20, and the annular boss 202 is provided with axial sliding grooves 203 having the same number as the hook portions of the fastening hook 11. When the cover body 1 is clamped with the base body 2, the clamping hook 11 passes through or slides through the axial sliding groove 203 along with the movement of the cover body 1 from top to bottom along the axial direction of the cylindrical main body 20, and then the cover body 1 is rotated along the circumferential direction of the cylindrical main body 20, so that the annular boss 202 and the clamping groove 14 are clamped with each other, and the clamping is completed. Here, when the annular projection 202 is engaged with the slot 14, the top surface of the hook (i.e., the protrusion) of the hook 11 contacts the bottom surface of the annular projection 202, as shown in fig. 2. Here, the tubular main body 20 may have a straight tubular structure with the inner diameters of the upper and lower ends being the same, or may have a tubular structure with the inner diameters of the upper and lower ends being different, for example, as shown in fig. 1, 2, and 5, the inner diameter of the tubular portion of the tubular main body 20 located above the annular boss 202 is larger than the inner diameter of the tubular portion located below the annular boss 202; thus, partial gas at the upper end of the tubular main body 20 is not easy to enter the lower end of the tubular main body 20 and further enter the steam outlet of other devices. For example, as shown in fig. 5, the outer surface of the annular boss 202 is a smooth surface, so that when the cover 1 and the base 2 are assembled and disassembled, the frictional resistance between the contact surfaces of the annular boss 202 and the hook 11 is reduced, thereby facilitating the sliding of the hook 11 along the circumferential direction of the cylindrical body 20.
