Description

Technical Field

[0001] The invention relates to the technical field of drainers, and in particular to a bouncing core with a shearing function. Background Art

[0002] Most of the commonly used drains on bathtubs and basins are pop-up drains, which are convenient to use. When using them, you only need to press the pop-up pressure plate on the pop-up drain to switch the pop-up pressure plate to the pop-up state. When the pop-up pressure plate is in the pop-up state, the pop-up drain is opened and water can be discharged; when the pop-up pressure plate on the pop-up drain is in the pressed state, the pop-up drain is in the closed state and water cannot be discharged.

[0003] However, the existing bouncing drain has the following problems: since the leakage hole area inside the bouncing drain is small, some solid objects such as hair and debris in the water can easily block the bouncing drain during the draining process, resulting in poor draining.

Therefore, the above terms should not be understood as limiting the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] like Figures 1 to 11 As shown, a bouncing core with shearing function comprises a launching jacket 1, a bouncing component 3, an upper cutting piece 4, and a lower cutting piece 8. The upper end of the launching jacket 1 is provided with an opening, and the lower end of the launching jacket 1 is provided with an exhaust port. The bouncing component 3 is arranged in the launching jacket 1, and the upper end of the bouncing component 3 is connected with a bouncing pressure plate 2; the bouncing pressure plate 2 is switched between a pressed state and a popped state by pressing the bouncing pressure plate 2;

[0033] The lower cutting piece 8 is slidably arranged in the launching jacket 1, and a spring 9 is arranged between the lower cutting piece 8 and the bouncing part 3; the upper cutting piece 4 is connected to the bouncing pressure plate 2, and the upper cutting piece 4 is correspondingly arranged above the lower cutting piece 8; by pressing the bouncing pressure plate 2, the upper cutting piece 4 is driven to move relative to the lower cutting piece 8 to achieve cutting of solid objects.

[0034] Among them, when the bouncing pressure plate 2 is in a downward pressed state, the bouncing pressure plate 2 is just located in the opening at the upper end of the launching jacket 1, and the bouncing pressure plate 2 blocks the opening. At this time, the bouncing core is in a closed state, and water cannot be discharged through the bouncing core; when the bouncing pressure plate 2 is in a bouncing state, the bouncing pressure plate 2 moves to the top of the opening. At this time, the bouncing core is in an open state, and water can be discharged through the bouncing core.

[0035] In the present invention, a lower cutting piece 8 and an upper cutting piece 4 are provided inside, and the upper cutting piece 4 is driven to move by pressing the bouncing pressure plate 2, thereby realizing relative movement between the upper cutting piece 4 and the lower cutting piece 8; if there are solid objects such as hair and debris in the bouncing core, the upper cutting piece 4 and the lower cutting piece 8 can cut or chop the solid objects such as hair and debris by pressing the bouncing pressure plate 2. For filamentary solid objects such as hair, the hair can be cut into strips of shorter length by the cutting action, which can promote the discharge of filamentary solid objects such as hair, and avoid the filamentary objects 12 such as hair being entangled in the bouncing core and causing blockage; and for granular solid objects such as debris, the debris can be cut into particles of smaller diameter by the cutting action, which is also more conducive to the discharge of the debris, thereby avoiding blockage in the bouncing core.

[0036] The present invention effectively solves the problem that the traditional bouncing drain is easily blocked, and ensures smooth drainage.

[0037] The lower end of the bouncing component 3 is provided with a first connecting thread 3-3, the lower end of the launching jacket 1 is provided with a through hole 1-2, the lower end of the bouncing component 3 passes through the through hole 1-2, and the first connecting thread 3-3 at the lower end of the bouncing component 3 is connected with a nut 10, and the bouncing component 3 is fixed by the nut 10. The bouncing component 3 is provided with a positioning plate 3-2, and the positioning plate 3-2 contacts the bottom of the launching jacket 1 to achieve axial positioning of the bouncing component 3. One end of the spring 9 contacts the positioning plate 3-2.

[0038] Further, the lower cutting member 8 includes a first ring body 4-1 and a first cutting portion 4-2 disposed at the upper end of the first ring body 4-1, and the upper cutting member 4 includes a second ring body 8-1 and a second cutting portion 8-2 disposed at the lower end of the second ring body 8-1; the first cutting portion 4-2 is provided with a cutting surface 4-2a, and the first cutting portion 4-2 is provided with a cutting edge 8-2a. The present invention also includes a directional rotating sleeve 7, the directional rotating sleeve 7 is connected to the spring pressure plate 2, the directional rotating sleeve 7 is provided with an inclined groove 7-1, and the outer side of the spring component 3 is provided with a convex pin 3-1, and the convex pin 3-1 is connected to the inclined groove 7-1 on the directional rotating sleeve 7.

[0039] Among them, the directional rotating sleeve 7, the bouncing pressure plate 2 and the upper cutting piece 4 are connected as a whole. The directional rotating sleeve 7 is connected to the bouncing pressure plate 2. The bouncing pressure plate 2 drives the directional rotating sleeve 7 to move synchronously when moving; during the downward pressing process, the bouncing pressure plate 2 drives the directional rotating sleeve 7 and the upper cutting piece 4 to move downward synchronously; during the downward movement of the directional rotating sleeve 7, due to the cooperation between the convex pin 3-1 and the inclined groove 7-1, the directional rotating sleeve 7 rotates while moving downward, and the directional rotating sleeve 7 drives the upper cutting piece 4 to rotate. Therefore, the upper cutting piece 4 rotates relative to the lower cutting piece 8 while moving downward relative to the lower cutting piece 8, so that the cutting edge 8-2a on the first cutting part 4-2 approaches the cutting surface 4-2a on the second cutting part 8-2 at an inclined angle until the cutting edge 8-2a contacts the cutting surface 4-2a, and cuts or shreds the solid matter. This method can not only provide a shear force in the vertical direction, but also provide a shear force in the horizontal direction, thereby improving the shearing effect, especially for some filaments 12 (such as hair, etc.). The cutting surface 4-2a is an inclined surface, and the cutting surface 4-2a forms an angle with the plane where the second ring body is located, and the angle is between 70° and 80°.

[0040] The first ring body 4-1 and the second ring body 8-1 are provided with hollow grooves. By providing the hollow grooves on the first ring body 4-1 and the second ring body 8-1, the hollow grooves are used to allow water to pass through.

[0041] The inner side of the launching jacket 1 is provided with a guide groove 1-4, and the outer side of the lower cutting member 8 is provided with a guide boss 8-3, and the guide boss 8-3 is arranged in the guide groove 1-4. The guide groove 1-4 is arranged along the axial direction of the launching jacket 1, and the lower cutting member 8 can move along the direction of the guide groove 1-4 through the cooperation between the guide boss 8-3 and the guide groove 1-4, and the rotation of the lower cutting member 8 is restricted.

[0042] The lower end of the launching jacket 1 is provided with a lower discharge port 1-3.

[0043] The upper end of the bouncing component 3 is provided with a second connecting thread 3-4, and the bouncing pressure plate 2 is provided with a threaded hole, and the upper end of the bouncing component 3 is connected to the threaded hole on the bouncing pressure plate 2 through the second connecting thread 3-4. A positioning pressure cap 6 is also provided between the bouncing pressure plate 2 and the directional rotating sleeve 7.

[0044] A first sealing ring 5 is arranged on the outer side of the spring pressure plate 2, and a second sealing ring 11 is arranged on the outer side of the launching jacket 1. A sealing ring positioning groove 1-1 is arranged on the outer side of the launching jacket 1, and the second sealing ring 11 is embedded in the sealing ring positioning groove 1-1. The second sealing ring 11 is used for sealing contact with the sewer pipe. The first sealing ring 5 is used for sealing cooperation with the opening at the upper end of the launching jacket 1.

[0045] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
