[0004] The above-mentioned improved water dropper bouncing assembly and water dropper reduce the sliding gap, making it difficult for impurities to enter the bouncing core. However, the bouncing core provides elastic force through the bouncing hook, and there must be positions at both ends of the bouncing hook for hooking. Therefore, a hole must be opened in the top of the bouncing tube, and a connecting position for the bouncing hook to hook must be machined on the top of the bouncing tube. It is also necessary to machine a connecting position for the bouncing hook to hook on the matching guide protrusion. This is inconvenient to manufacture, and the volume is not small enough. In addition, impurities are easily introduced into the sliding gap, which will cause pressing jams. In severe cases, it will cause jamming and inability to rebound, and the service life is not long.

DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the water discharger includes a gland 1 and a bouncing core 2. The bouncing core 2 includes a top cover 3, a guide cylinder 4, a rotating body 5 and a limiting cylinder 6. The top cover 3 is fixedly connected to the bottom of the gland 1. The guide cylinder 4 is inserted into the top cover 3 from bottom to top and is fixedly connected to the top cover 3. The inner wall of the guide cylinder 4 has four circumferentially uniformly distributed guide edges 41 extending vertically from the bottom to the middle. The guide cylinder 4 is inserted into the limiting cylinder 6 and the lower end of the guide cylinder 4 has a radially inwardly convex shoulder 42. The upper end of the limiting cylinder 6 has a radially outwardly turned and circumferentially uniformly distributed limiting block 61. The guide edge 41 is inserted between the corresponding limiting blocks 61. The rotating body 5 is inserted into the limiting cylinder 6 from top to bottom. The rotating body 5 is inserted into the limiting cylinder 6 from top to bottom. The upper end of the body 5 has a radially outwardly protruding and circumferentially uniformly distributed positioning block 51, the number of the positioning blocks 51 is consistent with the number of the guide edges 41, and a slide groove 52 for the guide edges 41 to pass through is formed between adjacent positioning blocks 51. The bottom of each positioning block 51 has an inclined surface 1 53 inclined from the right end to the middle thereof, and the bottom of each positioning block 51 has an inclined surface 2 54 inclined from the middle to the left end thereof. The top of each limit block 61 has a pointed protruding convex tooth portion 611. A spring 7 is provided between the top cover 3 and the rotating body 5. The spring 7 provides elastic force to keep the inclined surface 1 53 and the inclined surface 2 54 in contact with the corresponding convex tooth portion 611.

[0021] The water discharger is usually in the water discharge state, that is, the guide edge 41 is arranged between the corresponding limit block 61 and the positioning block 51, and the elastic force of the spring 7 makes the inclined surface 1 53 and the inclined surface 2 54 contact the convex tooth portion 611 of the corresponding limit block 61. Because the inclined surface 1 53 and the inclined surface 2 54 are both inclined, the elastic force of the spring 7 makes the rotating body 5 maintain the rotation trend toward the guide edge 41, and the positioning block 51 is blocked by the guide edge 41 and cannot rotate. The elastic force of the spring 7 also makes the shoulder 42 contact the convex tooth portion 611 of the corresponding limit block 61. When the water is discharged, the pressure cover 1 is pressed downward, and the pressure cover 1 drives the top cover 3 and the guide cylinder 4 to move downward until each guide edge 41 exits the slide groove 52 between the adjacent positioning blocks 51, and each guide edge 41 is still located between the corresponding limit blocks 61 and will not exit the limit blocks 61. The elastic force of the spring 7 causes the rotating body 5 to rotate, and the inclined surface 53 of the positioning block 51 is moved downward. The convex tooth portion 611 of another adjacent limit block 61 in the rotation direction abuts against the convex tooth portion 611 of the inclined surface 2 54 of the positioning block 51, which originally abuts against the convex tooth portion 611 of the inclined surface 1 53, and the gland 1 is released. The elastic force of the spring 7 provides a restoring force, but each guide edge 41 abuts against the intersection of the inclined surface 1 53 and the inclined surface 2 54 at the bottom of the corresponding positioning block 51, and the guide cylinder 4 cannot be lifted upward, so that the top cover 3 and the gland 1 cannot be lifted, thereby achieving the purpose of closing the water discharge. When the water discharge is needed again, By pressing the pressure cover 1, the pressure cover 1 drives the top cover 3 and the guide cylinder 4 to move downward, and each guide edge 41 withdraws from the intersection of the inclined surface 1 53 and the inclined surface 2 54 at the bottom of the corresponding positioning block 51. The elastic force of the spring 7 cooperates with the inclined surface 1 53 and the inclined surface 2 54 to rotate the rotating body 5. During the rotation process, the elastic force of the spring 7 also makes each guide edge 41 touch the inclined surface 2 54 of the corresponding positioning block 51 until the guide edge 41 slides into the corresponding slide groove 52, and then the water discharger returns to the normal water discharge state.

[0022] The overall volume of the drain is small, the top cover 3 seals the top of the guide tube 4 to prevent impurities from entering the interior, the gap between the guide tube 4 and the limit tube 6 is small to avoid clogging by impurities, there is no problem of jamming and blocking, pressing is smooth, and the service life is long.

[0023] To be more specific, the top surface of the guide rib 41 is a guide surface 411 that matches the inclined surface 1 53. When the guide rib 41 contacts the intersection of the inclined surface 1 53 and the inclined surface 2 54 at the bottom of the corresponding positioning block 51, the guide surface 411 fits the corresponding inclined surface 1 53, and the side of the guide rib 41 is abutted by the interface between the inclined surface 1 53 and the inclined surface 2 54, so that the positioning is stable, the pressure cover 1, the top cover 3 and the guide cylinder 4 will not shake, and the use effect is good.

[0024] The top cover 3 has a limiting column 31 inserted into the spring 7, the top end of the spring 7 abuts against the top cover 3, the spring 7 is inserted into the rotating body 5, and the bottom end of the spring 7 abuts against the inwardly folded retaining edge 55 at the bottom end of the rotating body 5. In this way, the spring 7 is limited by the limiting column 31, and the working stability of the spring 7 is good.

[0025] The top cover 3 is threadedly connected to the gland 1. This makes the connection convenient. In this embodiment, the outer wall of the top cover 3 has an external thread, the bottom of the gland 1 has a cylindrical connecting portion, the inner wall of the connecting portion has an internal thread, and the top cover 3 is threadedly connected to the connecting portion through the external thread.

[0026] The inner wall of the top cover 3 has four circumferentially evenly distributed snap-in grooves, and the outer wall of the guide cylinder 4 has snap-in buckles 43 snapped into the corresponding snap-in grooves. The top cover 3 and the guide cylinder 4 are fixedly connected by snap-in, and the connection is stable. In this embodiment, the snap-in buckle 43 of the guide cylinder 4 is tilted and folded downward, so that the snap-in process is smooth. After being clamped, the bottom edge of the snap-in buckle 43 abuts against the bottom of the snap-in groove, and the top edge of the snap-in buckle 43 abuts against the top of the snap-in groove, and the connection is stable.

[0027] The outer wall of the top cover 3 is embedded with a sealing ring 8. The sealing ring 8 ensures a sealing effect and plays a role in isolating water.
