Fig. 3 is a partial enlarged view at a of fig. 2.

As shown in fig. 1-2, the drain plug 100 includes a housing 10 and a bounce filter assembly removably disposed in the housing 10, wherein the bounce filter assembly includes a bounce core 20, a press cover 30, and a filter frame 40. The shell 10 is used for being arranged in the drainer in a removable way, and the bouncing core 20 and the filtering frame 40 are arranged in the shell 10; the pressing cover 30 is connected to the upper end of the bouncing core 20 through threads, and a user drives the bouncing core 20 to bounce by pressing the pressing cover 30; one of the bouncing core 20 and the filtering frame 40 is provided with a plug-in part, and the other is provided with a plug-in matching part, so that the bouncing core 20 and the filtering frame 40 are detachably connected through the mutual matching of the plug-in part and the plug-in matching part.

The present embodiment will be described in detail taking the example in which the insertion and extraction portion 21 is provided on the bouncing core 20. As shown in fig. 2, the bottom end of the bouncing core 20 has a plug portion 21, the middle of the filtering frame 40 has a plug mating portion, in this embodiment, the plug mating portion is a socket 41, the plug portion 21 is detachably inserted into the socket 41, and the plug portion 21 deforms during the process of inserting into the socket 41 and pulling out from the socket 41.

As shown in fig. 3, the plug portion 21 includes at least two limiting abutments 212 (two limiting abutments 212 located at the bottom of the plug portion 21 in the present embodiment in the drawing) extending in the direction of the socket 41 and capable of being inserted into the socket 41, and an open slot 211 (the open slot is in a straight shape when the number of the limiting abutments 212 is two) extending outward from top to bottom is formed between the limiting abutments 212.

The upper portion of the inner side surface of the socket 41 toward one end of the insertion/extraction portion 21 is a guide surface 42, the guide surface 42 having a shape gradually shrinking inward along the insertion direction of the insertion/extraction portion 21 (i.e., the shape in which the upper portion of the socket 41 is shrunk inward from top to bottom as shown in fig. 3); the other end of the socket 41 has a limiting surface 43 on the inner surface thereof, and the limiting surface 43 has a gradually expanding shape along the insertion direction of the insertion/extraction portion 21 (i.e., a shape in which the lower portion of the socket 41 expands outwardly from top to bottom as shown in fig. 3).

When the plug 21 is to be inserted into the socket 41, the sliding surface 216 contacts the guiding surface 42, moves downward along the guiding surface 42, and the two limiting abutments 212 approach each other during the movement, and the sliding surface 216 cooperates with the guiding surface 42 to perform guiding function. As shown in fig. 3, when the insertion/extraction portion 21 is inserted into the insertion hole 41, the first contact surface 213 contacts the guide surface 42, and the second contact surface 215 contacts the stopper surface 43. And the width of the position with the largest distance between the outer walls of the second abutting surfaces 215 on the two sides is larger than the width of the position with the smallest distance between the top ends of the limiting surfaces 43, so that the protruding part 214 can be clamped in the limiting surfaces 43 under the action of no external force, and firm connection between the bouncing core and the filter frame is ensured.
