[0038] The utility model will be further described below with specific examples in combination with the drawings, referring to Figure 1 — Figure 4 :

[0039] Example one:

[0040] A drain core, comprising a drain shell 1 with an upper mounting port, a water outlet hole 10 is formed in the center of the bottom of the drain shell 1, a drain basket 2 is arranged in the drain shell 1, a movable hole 20 is formed in the middle of the drain basket 2, a press cylinder 3 that can stretch up and down is arranged in the movable hole 20, an abutment port 30 is formed in the bottom of the press cylinder 3, a bounce core 4 is arranged below the press cylinder, an abutment ring 40 for abutting with the bottom of the press cylinder 3 is arranged on the side wall of the bounce core 4, a mounting ring groove 41 is arranged on the side wall of the bounce core 4, a sealing soft ring 5 is embedded in the mounting ring groove 41, and a connection end 6 for fixing with the bottom of the drain shell 1 is arranged on the bottom of the bounce core 4, when the press cylinder 3 is pressed and drives the bounce core 4 to move downwards, the sealing soft ring 5 on the side wall of the bounce core 4 is pressed downwards and seals the water outlet hole 10.

[0041] Specifically, during the process of pressing to seal the water outlet hole, the user presses the press cylinder 3 downwards, the abutment ring 40 is pressed downwards through the abutment port 30 in the bottom of the press cylinder, the bottom of the bounce core is fixed, the whole bounce core 4 is squeezed, and the sealing soft ring 5 on the side wall of the bounce core also moves downwards, at this time, the sealing soft ring blocks the water outlet, and the water sealing effect is realized.

[0042] The bounce core is squeezed again according to its structure principle, the outer shell part of the bounce core is moved upwards by the reset function inside the bounce core, the sealing soft ring 5 is moved upwards, so that the water outlet hole is no longer blocked, and the drain effect is realized.

[0043] In the above structure, the sealing soft ring is fixed in the embedded way on the side wall of the bounce core, compared with the traditional structure of arranging a mounting ring and then embedding, the diameter of the sealing soft ring is greatly reduced, so that the water sealing effect can be realized on the drain hole with a smaller diameter, such as a washbasin and a bathroom.

[0044] In addition, if the core is used for the sewer of a large-diameter drain outlet such as a kitchen vegetable basin, a larger sealing ring can be replaced by disassembly, so that the core has a wider application range.

[0045] Preferably, the connecting end 6 comprises a threaded hole 42 opened at the bottom of the bounce core 4, and the water outlet hole 10 is provided with a mounting bracket 100, the middle part of the mounting bracket 100 is provided with a mounting hole 101 corresponding to the threaded hole 42, and the mounting hole 101 and the threaded hole 42 are screwed to fix the bottom of the bounce core 4 to the bottom of the sewer shell 1.

[0046] In the above structure, the connecting end is used as the fixing form of the bottom of the bounce core 4, which is screwed through the mounting hole 101 to ensure that the inner core of the core does not move, and the outer wall moves with the pressing of the pressing cylinder.

[0047] Embodiment two:

[0048] Compared with embodiment one, the connecting end 6 comprises a connecting vertical rod 60, the water outlet hole 10 is provided with a mounting bracket 100, the middle part of the mounting bracket 100 is provided with a mounting hole 101, the connecting vertical rod 60 penetrates the mounting hole 101, the side wall of the connecting vertical rod 60 is provided with a limiting groove 600, and the limiting groove 600 is provided with a limiting part 601 driven by an elastic element. When the connecting vertical rod 60 is inserted into the mounting hole 101, the limiting part 601 is fixed to the bottom of the sewer shell 1 by limiting clamping.

[0049] In another embodiment, the connecting end is in the form of a connecting vertical rod 60 to fix the bottom of the core, and a limiting part 601 driven by an elastic element is arranged at the bottom to clamp and limit. The specific elastic element can be a spring or a spring piece, and the limiting part 601 can be a pin with inclined surfaces on the upper and lower parts or a ball. In this way, the core can be fixed in the mounting hole 101 in a plug-in and plug-out form, and the core and the connecting vertical rod 60 can be pulled out under a certain force of the user.

[0050] Preferably, the connecting vertical rod 60 is detachably connected to the bottom of the bounce core 4 by screwing.

[0051] Further, since the connecting vertical rod 60 has certain processing requirements, it can be independently processed and detachably fixed to the bottom of the bounce core 4 by screwing.

[0052] Preferably, the sealing ring 5 comprises an embedded ring 50 embedded in the mounting ring groove 41, the outer edge of the embedded ring 50 extends downward and forms a sealing cylinder 51, and the bottom of the sealing cylinder 51 extends outward and forms a sealing plug ring 52 for sealing the water outlet hole 10.

[0053] In the above structure, considering that there may be different depths in practice, since the sealing soft ring 5 can be conveniently disassembled, the sealing cylinder 51 of different sizes and the sealing plug ring 52 of different diameters have different application ranges, and actual users can replace them according to needs.

[0054] Preferably, the upper end of the mounting hole 101 is provided with an upper sealing soft ring 7 in the shape of a horn, and the horn opening of the upper sealing soft ring 7 is vertically upward. When the pressing cylinder 3 is pressed to the bottom, the upper sealing soft ring 7 seals the gap between the sealing cylinder 51 and the outer wall of the bounce core 4.

[0055] In the implementation process, water in the drain will seep from the inside of the bounce core, causing water leakage. The upper sealing soft ring 7 provided can seal the gap between the sealing cylinder 51 and the outer wall of the bounce core 4 when the sealing soft ring 5 moves downward, thereby reducing the seepage of water from the inside of the bounce core.

[0056] Preferably, the bounce core 4 includes an outer core 43 and an inner core 44 moving in the outer core 43 through a spring, and the abutting ring 40 and the mounting ring groove 41 are arranged on the outer wall of the outer core 43. The connecting end 6 is arranged at the bottom of the inner core 44.

[0057] It is worth mentioning that the bounce core is in an inverted form compared to the traditional one. In the traditional bounce core, the outer shell is fixed, and the inner core moves up and down. The above design fixes the inner core and inverts the outer core, allowing the outer core to move up and down. This way, the drain basket can be set deeper, and more kitchen or bathroom garbage can be stored.

[0058] Preferably, the inner hole of the movable hole 20 is provided with a sliding sleeve 21 in interference fit, and the pressing cylinder 3 slides up and down along the sliding sleeve 21. The sliding sleeve 21 can play a guiding role to prevent tilting.

[0059] Preferably, a soft ring gap 22 is arranged between the sliding sleeve 21 and the pressing cylinder 3.

[0060] In the above implementation process, when the drain basket is deep, the unsealed sealing soft ring 5 can extend into the soft ring gap 22 by deformation; and when sealing water, the sealing soft ring 5 is extruded out of the soft ring gap 22 to seal the water outlet hole. The soft ring gap 22 can provide a deeper drain basket.

[0061] Preferably, the outer wall of the drain housing 1 is provided with several layers of mounting rubber rings 11. This facilitates the fastening and installation of the drain housing.

[0062] The above embodiment is only a preferred embodiment of the utility model, and does not limit the protection scope of the utility model, so that: all equivalent changes made according to the structure, shape, principle of the utility model should be covered in the protection scope of the utility model.
