In some embodiments, as shown in fig. 3 and 4, the side wall of the recess 21 remote from the central axis of the bore seal 20 abuts the outer circumferential surface of the extension 114. When groove 21 is fitted with drain hole 12, the side wall of groove 21 adjacent to the central axis abuts against the inner peripheral surface of extension portion 114, the side wall of groove 21 away from the central axis abuts against the outer peripheral surface of extension portion 114, the inner peripheral surface and the outer peripheral surface of extension portion 114 abut against two side walls of groove 21 in the radial direction, the two side walls of groove 21 can form a clamp for extension portion 114, and the inner peripheral surface and the outer peripheral surface of groove 21 and extension portion 114 are both in interference fit. Therefore, the two radial side walls of the groove 21 along the sealing plug 20 are respectively abutted against the inner and outer peripheral surfaces of the extension portion 114, so that the sealing performance of the groove 21 and the extension portion 114 can be improved, only one side is abutted against to realize a sealing mode, the sealing of the sealing plug 20 to the liquid discharge hole 12 can be improved by abutting both sides of the liquid discharge hole 12 against the sealing plug 20, the flow path of liquid at the joint of the groove 21 and the extension portion 114 is increased, and the sealing performance of the liquid discharge hole 12 of the machine body 10 is improved.

That is, only the first sidewall 211 extends obliquely along the direction of the central axis of the liquid discharge hole 12 toward the center of the machine body 10 and gradually away from the central axis, and the second sidewall 212 also extends obliquely along this direction, at this time, the slope of the generatrix on the inner circumferential surface of the second sidewall 212 may be smaller than the slope of the generatrix on the inner circumferential surface of the first sidewall 211, so as to ensure that the liquid discharge hole 12 at least abuts against the second sidewall 212 when being matched with the groove 21, so that the sealing plug 20 is matched with the liquid discharge hole 12 more tightly. Therefore, the slope of the second sidewall 212 is smaller than that of the first sidewall 211, so that the second sidewall 212 has certain guidance, the liquid discharge hole 12 can conveniently penetrate through the first sidewall 211 to be matched with the second sidewall 212, the difficulty in installing the sealing plug 20 is reduced, and the sealing plug 20 and the liquid discharge hole 12 can be matched more conveniently and more easily in a labor-saving manner.

When the plug 20 is fitted to the drain hole 12, the first circumferential section 1141 abuts against the inner circumferential surface of the sidewall of the recess 21 in the direction away from the central axis of the plug 20, and the second circumferential section 1142 is spaced apart from the inner circumferential surface of the sidewall of the recess 21 in the direction away from the central axis. The inner circumferential surface of the extension 114 faces away from the center of the body 10 along the central axis of the sealing plug 20, and the cross-sectional area of the inner circumferential surface may gradually increase, increasing the flow rate of the liquid flowing from the discharge hole 12 into the extension 114 and increasing the outflow rate of the liquid. Therefore, the second peripheral section 1142 extends obliquely in the direction toward the central axis with respect to the first peripheral section 1141, so that the drainage hole 12 has a guiding function, when the drainage hole 12 is matched with the groove 21, the drainage hole 12 can conveniently extend into the groove 21, and the mounting efficiency of the sealing plug 20 and the drainage hole 12 is improved.
In some embodiments, the first perimeter section 1141 extends obliquely in a direction from the extension 114 toward the center of the body 10 and toward the central axis of the sealing plug 20, and the absolute value of the slope of the first perimeter section 1141 is smaller than the absolute value of the slope of the second perimeter section 1142. It will be appreciated that the outer circumferential surface of the extension 114 comprises a first circumferential surface section 1141 and a second circumferential surface section 1142 each extending obliquely in the circumferential direction of the extension 114 towards the central axis of the sealing plug 20, the slope of the inclination of the first circumferential surface section 1141 being less than the slope of the inclination of the second circumferential surface section 1142. Therefore, by making the slope of first peripheral section 1141 smaller than the slope of second peripheral section 1142, it is convenient to increase the convenience when extending portion 114 is engaged with groove 21, and at the same time, it is ensured that extending portion 114 and groove 21 stop against each other to form a seal for discharge hole 12.
In some embodiments, referring to fig. 6 and 7, the surface of the side of the sealing plug 20 facing the center of the body 10 is provided with a first annular structure and a second annular structure which are radially spaced apart, the first annular structure is located radially inside the second annular structure, a groove 21 is defined between the first annular structure and the second annular structure, and the length of the first annular structure in the axial direction of the sealing plug 20 is greater than that of the second annular structure in the axial direction of the sealing plug 20. The first and second annular formations are spaced radially of the sealing plug 20 and define a recess 21, the recess 21 being adapted to engage with the extension 114. The axial length of the first annular structure is greater than the axial length of the second annular structure, so that the first annular structure extends into the extension portion 114 to be matched with the extension portion 114, the sealing performance of the extension portion 114 is improved, the first annular structure can be made of rubber, the second annular structure can be made of plastic, and when the groove 21 is matched with the extension portion 114, at least part of the first annular structure can elastically deform to abut against the inner circumferential surface of the extension portion 114.
