Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to a magnetic floor drain core. Background Technology

[0002] Odor-proof drain cores are bathroom accessories used in bathrooms. They are mainly used to guide water from the bathroom to the sewer, while also sealing off odors from the sewer to prevent them from spreading into the bathroom.

[0003] For example, utility model patent application number 202120882088.X specifically discloses a quick-assembly odor-proof floor drain core, combined with its disclosed technical content and appendix. Figure 4 It can be seen that by installing the rotating shaft of the sealing plate 2, the first magnetic unit 3, and the second magnetic unit 4 between the main body 1 and the base plate 5, the base plate 5 is provided with an installation groove 51, an installation buckle 52, and a magnetic unit placement groove 53 for placing the second magnetic unit 4.

[0004] The outer wall of body 1 is provided with mounting ribs 11 that mate with mounting grooves 51 and mounting recesses 12 that mate with mounting clips 52. From its attached... Figure 1 and 4 It is understood that the base plate 5 shields and fixes the rotating shaft of the sealing plate 2, the first magnetic unit 3, and the second magnetic unit 4, preventing the above structures from being directly exposed and causing an unsightly appearance of the drain core. During installation, the mounting groove 51 is aligned with the mounting rib 11 and inserted, and the mounting clip 52 is snapped into the mounting recess 12. At this time, the first magnetic unit 3 is fixed between the base plate 5 and the main body 1. However, the above installation method can only limit and fix the base plate 5 in the axial direction of the drain core, but it cannot limit and fix the base plate 5 in the radial direction of the drain core. This makes the base plate 5 prone to loosening and producing abnormal noise, and it is even easy to fall off due to external forces. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a magnetic drain core, which solves the problem that the base plate is easy to loosen and cause abnormal noise in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a magnetic drain core, comprising...

[0007] The core has a cavity with openings at both the top and bottom. The inner wall of the cavity is integrally formed with a partition plate, which protrudes radially along the cavity. The partition plate has a water outlet, and two spaced-apart support plates are fixed at the bottom of the partition plate. The two support plates protrude axially along the cavity.

[0008] A valve plate, one end of which is rotatably disposed between the two support plates, and one end of the valve plate is provided with a first magnetic suction element, and the other end of the valve plate is provided with a sealing element, which can seal the water outlet;

[0009] The base is connected to the two support plates by a snap-fit ​​structure. The base is sandwiched between the support plates and the inner wall of the cavity, and the base is provided with a second magnetic attractor that magnetically engages with the first magnetic attractor.

[0010] As a further embodiment, slots are provided on both support plates, and the two ends of the base are respectively inserted into the slots of the two support plates.

[0011] As a further embodiment, the buckle structure includes a slot provided on the inner wall of the slot or the side of the base, and a protrusion provided on the side of the base or the inner wall of the slot, wherein the protrusion engages with the slot.

[0012] As a further embodiment, one end of the valve plate is integrally formed with a rotating shaft, and both support plates are provided with shaft holes, the two ends of the rotating shaft being rotatably engaged with the shaft holes on the two support plates.

[0013] As a further embodiment, a first receiving groove is provided on the rotating shaft, and the first magnetic member is inserted into the first receiving groove;

[0014] The base has a second receiving groove, and the second magnetic component is inserted into the second receiving groove.

[0015] As a further embodiment, the side of the base is shaped like an arc to match the inner wall of the cavity.

[0016] As a further embodiment, the bottom of the base is integrally formed with a baffle, the baffle protruding radially along the cavity, and the baffle is located between the two support plates and below the rotating shaft.

[0017] As a further embodiment, the sidewalls of the two support plates are provided with guide grooves. One end of the guide groove extends to the bottom edge of the support plate, and the other end of the guide groove extends to the shaft hole.

[0019] A raised ridge is integrally formed along the edge of the water outlet. The raised ridge protrudes along the axial direction of the cavity, and the two ridges are connected end to end to form a circle. The raised ridge can abut against the plate surface of the sealing element.

[0020] As a further embodiment, the valve plate is provided with a positioning hole that penetrates the plate surface, and a positioning flange is integrally formed on the bottom surface of the seal, the positioning flange being engaged in the positioning hole;

[0021] Along the axial direction of the cavity, the diameter of the positioning flange gradually increases from top to bottom, and the diameter of the positioning hole gradually increases from top to bottom.

[0022] The beneficial effects of this utility model are as follows: A partition is integrally formed on the inner wall of the cavity, and two spaced-apart support plates are provided at the bottom of the partition. The base is connected to the two support plates via a snap-fit ​​structure, thus fixing the base to the two support plates.

Furthermore, the rotating structure between one end of the valve plate and the two support plates, as well as the base, can be hidden inside the cavity. Compared to traditional drain cores with rotating structures and bases exposed on the outer wall of the core, the drain core of this embodiment has a more aesthetically pleasing appearance, and the base, being inside the cavity, is protected from external forces that could cause it to fall off.

[0035] As attached Figure 1-3 As shown, this embodiment provides a magnetic drain core, including...

[0036] The core 1 has a cavity 11 with openings at both the top and bottom. A partition 12 is integrally formed on the inner wall of the cavity 11, protruding radially along the cavity 11. The partition 12 has a water outlet 13 for draining water from the cavity 11. Two spaced-apart support plates 14 are fixed to the bottom of the partition 12, specifically integrally formed with the partition 12, and protruding axially along the cavity 11.

[0037] Valve plate 2, one end of which is rotatably disposed between two support plates 14, and one end of valve plate 2 is provided with a first magnetic suction element 6, and the other end of valve plate 2 is provided with a sealing element 3, which can seal the water outlet 13.

[0038] The base 4 is connected to the two support plates 14 via a snap-fit ​​structure 5, thus fixing the base 4 to the two support plates 14. The base 4 can bear force and be fixed in the axial direction of the cavity 11, and is clamped between the support plates 14 and the inner wall of the cavity 11, allowing the base 4 to also bear force and be fixed in the radial direction of the cavity 11. Furthermore, the rotational structure between one end of the valve plate 2 and the two support plates 14, as well as the base 4, can be hidden inside the cavity 11, resulting in a more aesthetically pleasing appearance compared to traditional drain cores exposed on the outer wall of the core 1. The base 4 is equipped with a second magnetic element 7 that magnetically engages with the first magnetic element 6. The first magnetic element 6 and the second magnetic element 7 can be selected to be mutually magnetically attracted magnets.

[0039] When the water in the cavity 11 accumulates to a weight greater than the magnetic attraction between the first magnetic element 6 and the second magnetic element 7, one end of the valve plate 2 rotates around the support plate 14, and the seal 3 at the other end of the valve plate 2 disengages from the outlet 13, thereby allowing water to be discharged from the outlet 13. When the water in the cavity 11 is discharged to a certain extent, the first magnetic element 6 and the second magnetic element 7 attract each other magnetically, causing one end of the valve plate 2 to rotate around the support plate 14, and once again causing the seal 3 at the other end of the valve plate 2 to seal the outlet 13, preventing sewage backflow and small animals from crawling in.

[0040] In this embodiment, a partition 12 is integrally formed on the inner wall of the cavity 11, and two support plates 14 are spaced apart at the bottom of the partition 12. The base 4 is snapped to the two support plates 14 through a snap-fit ​​structure 5, thereby fixing the base 4 to the two support plates 14. The base 4 can bear force and be fixed in the axial direction of the cavity 11, and the base 4 is sandwiched between the support plates 14 and the inner wall of the cavity 11, so that the base 4 can also bear force and be fixed in the radial direction of the cavity 11. In summary, the base 4 can bear force in both the axial and radial directions of the cavity 11, thereby limiting and fixing the base 4 and preventing it from loosening and producing abnormal noise. In addition, the rotating structure between one end of the valve plate 2 and the two support plates 14 and the base 4 can be hidden inside the cavity 11. Compared with the traditional drain core with a rotating structure and the base 4 exposed on the outer wall of the core 1, the drain core of this embodiment has a more beautiful appearance, and the base 4 is also prevented from falling off due to external forces because it is inside the cavity 11.

[0041] For details, see attached. Figure 6-8 As shown, each of the two support plates 14 has a slot 141. Preferably, the slot 141 is located on the side of the support plate 14 near the inner wall of the cavity 11. The two ends of the base 4 are respectively inserted into the slots 141 of the two support plates 14, so that the base 4 is clamped between the support plate 14 and the inner wall of the cavity 11, which limits and fixes the base 4 in the radial direction of the cavity 11. The side of the base 4 is arc-shaped to match the inner wall of the cavity 11, so that the base 4 fits more closely to the inner wall of the cavity 11 and the base 4 is clamped more tightly.

[0042] Further details are attached. Figure 4 , 6 As shown, the snap-fit ​​structure 5 includes a slot 51 disposed on the inner wall of the slot 141 or the side of the base 4, and a protrusion 52 disposed on the side of the base 4 or the inner wall of the slot 141, the protrusion 52 engaging with the slot 51. There are two embodiments: one where the snap-fit ​​structure 5 includes a slot 51 disposed on the inner wall of the slot 141 and a protrusion 52 disposed on the side of the base 4, the protrusion 52 engaging with the slot 51, this embodiment is preferred; the other where the snap-fit ​​structure 5 includes a slot 51 disposed on the side of the base 4 and a protrusion 52 disposed on the inner wall of the slot 141, the protrusion 52 engaging with the slot 51. In the axial direction of the cavity 11, both embodiments of the snap-fit ​​structure 5 can fix the base 4 between the support plate 14 and the inner wall of the cavity 11. Inserting the base 4 into the slot 141 and fixing it with the snap-fit ​​structure 5 facilitates installation.

[0043] As a further option, see attached Figure 6-8 As shown, one end of the valve plate 2 is integrally formed with a rotating shaft 21, and both support plates 14 are provided with shaft holes 142. The two ends of the rotating shaft 21 are rotatably engaged with the shaft holes 142 on the two support plates 14, so that the valve plate 2 can rotate relative to the two support plates 14.

[0044] Among them, as attached Figure 3 As shown, the rotating shaft 21 has a first receiving groove 211, and the first magnetic member 6 is inserted into the first receiving groove 211 to support the first magnetic member 6. The base 4 has a second receiving groove 41, and the second magnetic member 7 is inserted into the second receiving groove 41 to support the second magnetic member 7. The first magnetic member 6 and the second magnetic member 7 magnetically engage, thereby driving the sealing member 3 on the valve plate 2 to seal the water outlet 13.

[0045] As attached Figure 3 , 7 As shown in Figure 8, a baffle 42 is integrally formed on the bottom of the base 4. The baffle 42 protrudes radially along the cavity 11 and is located between the two support plates 14 and below the rotating shaft 21. The baffle 42 serves to shield the rotating shaft 21 on the one hand, and on the other hand, the baffle 42 can bear force, making it convenient to manually insert the base 4 between the support plate 14 and the inner wall of the cavity 11.

[0046] Additionally, as attached Figure 3 , 7As shown in Figure 8, during installation, guide grooves 143 are provided on the side walls of the two support plates 14. One end of the guide groove 143 extends to the bottom edge of the support plate 14, and the other end of the guide groove 143 extends to the shaft hole 142. Along the axial direction of the shaft hole 142, the groove depth of the guide groove 143 gradually decreases from the bottom end near the support plate 14 to the end near the shaft hole 142, so as to facilitate pressing the two ends of the rotating shaft 21 into the shaft hole 142 of the two support plates 14 through the guide groove 143.

[0047] In some embodiments, as shown in Appendix 9, the sealing element 3 is plate-shaped, and the top surface of the valve plate 2 is provided with a limiting groove 22. The sealing element 3 is placed in the limiting groove 22, thereby limiting and fixing the plate-shaped sealing element 3. A protruding rib 131 is integrally formed along the edge of the outlet 13. The protruding rib 131 protrudes along the axial direction of the cavity 11, and the protruding rib 131 is connected end to end to form a circle. The protruding rib 131 can abut against the plate surface of the sealing element 3. Compared with the flat edge of the outlet 13, which is prone to gaps between itself and the plate-shaped sealing element 3, the sealing element 3 is more easily indented due to the small contact area between the protruding rib 131 and the plate-shaped sealing element 3, resulting in better sealing performance and sealing effect. Generally, the sealing element 3 can be a silicone gasket.

[0048] As attached Figure 5 As shown, the valve plate 2 has a positioning hole 23 that penetrates the plate surface, and a positioning flange 31 is integrally formed on the bottom surface of the seal 3. The positioning flange 31 is engaged in the positioning hole 23, which can fix the seal 3 on the valve plate 2. Furthermore, along the axial direction of the cavity 11, the diameter of the positioning flange 31 gradually increases from top to bottom, and the diameter of the positioning hole 23 gradually increases from top to bottom. This increases the force between the positioning flange 31 and the positioning hole 23 after the positioning flange 31 is engaged in the positioning hole 23, thereby increasing the resistance and making it difficult for the seal 3 to loosen from the valve plate 2.

[0049] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
