Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically to a sink drain device. Background Technology

[0002] Current technology for washing sinks used for cleaning and laundry does not require the same level of filtration as kitchen sinks or basins. Washing sink drains prioritize the rapid removal of soapy water, clothing fibers, and other impurities, necessitating a high-volume drainage capacity. Therefore, current washing sink drains typically employ open drain outlets and built-in filter baskets to intercept large particles, allowing for the direct dumping of wastewater or rinse water during laundry.

[0003] Existing open-drainage sink drains have exposed drain outlets and filters, which affects visual neatness and pose a risk of small items falling during use. More importantly, during washing, socks, underwear, thin fabrics, and other clothing can easily be sucked into the drain or hooked around the edge of the drain outlet, making them difficult to remove or even damaging.

[0004] In view of this, this case conducts an in-depth study on the above-mentioned problems and proposes a sink drain device that can solve the aforementioned technical problems, thus giving rise to this case. Utility Model Content

[0005] The purpose of this invention is to provide a sink drain device that can effectively prevent the risk of clothes being sucked in or caught.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A sink drain assembly includes a base, a spring-loaded core installed in the base, a filter screen, and a seal; an overlapping edge is formed on the upper periphery of the base; a large cover located above the base is mounted on the spring-loaded core, and the projection of the large cover at least covers the inner periphery of the overlapping edge.

[0008] Furthermore, the projection of the periphery of the large cover completely covers the overlapping edge.

[0009] Furthermore, the back of the large cover has a sleeve portion for engaging with the bouncing core.

[0010] Furthermore, a plurality of guide strips extending along the axial direction of the sleeve are formed on the inner wall of the sleeve portion.

[0011] Furthermore, the large cover includes an upper cover and a lower cover, with the upper cover covering the outer edge of the lower cover through an edge-wrapping structure; the lower cover has an annular rib formed on its lower surface at a position corresponding to the edge-wrapping structure.

[0012] Furthermore, the upper and lower ends of the base are respectively formed with a drain outlet and a water outlet, and an annular guide groove is formed inside the base. The radial width of the annular guide groove at the drain outlet is greater than or equal to the radial width of the overlapping edge.

[0013] Furthermore, the inner surface of the large cover is formed with several radially distributed guide ribs.

[0014] Furthermore, the bouncing core includes an inner core and an outer shell that bounces up and down with the inner core; the lower end of the base is provided with a water outlet, a connecting arm located on the water outlet, and a mounting seat located on the connecting arm, and the inner core is mounted on the mounting seat.

[0015] Furthermore, a connecting seat is inverted at the upper end of the bouncing core, and the filter screen is disposed on the connecting seat.

[0016] Furthermore, the sealing element is located at the outer periphery of the bouncing core; or a connecting seat is inverted on the upper end of the bouncing core, and the sealing element is located on the connecting seat.

[0017] With the above solution, the new type of sink drainer is equipped with a large cover on the spring core. When in use, pressing the large cover drives the spring core to spring, thereby opening the drainer to drain water or closing it to stop water flow.

[0018] When the drain is shut off, the large cover sinks down with the spring core and latches onto the base. The projection of the large cover's perimeter covers at least the inner perimeter of the overlapping edge. All other parts of the drain, except for the large cover or the large cover and part of the overlapping edge, are hidden under the large cover. This effectively prevents the risk of clothes being sucked into the drain or caught inside or on the edge of the drain during washing and cleaning in the sink. Attached Figure Description

[0025] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] This case involves a sink drainer, which refers to a drainer applied to a sink. Sinks are usually balcony sinks located on balconies and are mainly used for washing clothes, mops, and other cleaning purposes.

[0027] like Figure 1-3 This is an embodiment of a sink drain assembly, comprising a base 1, a spring-loaded core 2 installed within the base 1, a filter screen 3, and a sealing element 4. Pressing the spring-loaded core 2 causes it to spring, and the sealing element 4 moves accordingly, having a first position where it seals against the base 1 to close the drain and cut off water, and a second position where it separates from the base 1 to open the drain and allow water to flow.

[0028] The upper periphery of the seat 1 of this invention has an overlapping edge 11. The bouncing core 2 is fitted with a large cover 5 located above the seat 1, and the projection of the large cover 5 covers at least the inner periphery of the overlapping edge 11.

[0029] Using the above technical solution, this novel sink drain is equipped with a large cover 5 on the spring-loaded core 2. In use, pressing the large cover 5 drives the spring-loaded core 2 to spring, thus opening the drain for drainage or closing it to stop water flow. The structure and working principle of the spring-loaded core 2 are existing known technologies.

[0030] When the drain is shut off, the large cover 5 sinks down with the spring core 2 and latches onto the base 1. The projection of the large cover 5 at least covers the inner periphery of the overlapping edge 11. All other parts of the drain except the large cover 5 or the large cover 5 and part of the overlapping edge 11 are hidden under the large cover 5. Thus, during the cleaning and washing process of the washing sink, the risk of small items such as the corners of clothes, especially socks, underwear, and thin fabrics, being sucked into the drain or hooked inside or on the edge of the drain can be effectively eliminated.

[0031] Furthermore, such as Figure 1-3 As shown, the projection of the periphery of the large cover 5 completely covers the overlapping edge 11, meaning the projection of the periphery of the large cover 5 covers at least to the outer periphery of the overlapping edge 11. In this closed drain state, all other components of the drain, except for the large cover 5, are hidden beneath it, further reducing the risk of snagging or damaging clothing.

[0032] When the drain is in the draining state, the large cover 5 bounces upward with the spring core 2, forming an annular drainage channel between the large cover 5 and the overlapping edge 11. The water flows through the annular drainage channel before flowing into the seat 1. Compared with the prior art, the annular drainage channel can rectify the water flow to speed up the drainage flow, and can stop objects that accidentally flow into the drain with the water flow. It can also block dirt and garbage that flow back onto the filter screen 3 inside the drain due to water scouring.

[0033] like Figure 3 As shown, the back of the large cover 5 has a sleeve portion 51 for receiving and engaging with the bouncing core 2. The large cover 5 is received and engaged by the sleeve portion 51, making it very simple and convenient to remove the large cover 5 from the bouncing core 2 or to install the large cover 5 onto the bouncing core 2.

[0034] Furthermore, a plurality of guide strips 511 extending along the sleeve axis are formed on the inner wall of the sleeve portion 51, which guide and reduce friction, thus making the disassembly and assembly of the large cover 5 easier and providing a better user experience.

[0035] like Figure 2 As shown, the large cover 5 includes an upper cover 53 and a lower cover 54. The upper cover 53 covers the outer edge 54 of the lower cover through an edge-wrapping structure. An annular rib 541 is formed on the lower surface of the lower cover 54 near the edge-wrapping structure. The upper cover 53 and the lower cover 54 can be made of different materials according to actual needs. The annular rib 541 reduces contact, collision, or friction between the large cover 5 and the overlapping edge 11 of the base 1 when they are fastened together, improving structural durability and user experience.

[0036] like Figure 2 As shown, the upper and lower ends of the base 1 are respectively formed with a drain outlet 121 and a drain inlet 122. An annular guide groove 12 is formed inside the base 1. The radial width of the annular guide groove 12 corresponding to the drain outlet 121 is greater than or equal to the radial width of the overlapping edge 11; in a preferred embodiment, the two widths are approximately equal. Thus, the overlapping edge 11 forms an annular guide platform, and the annular drainage channel formed between the large cover 5 and the overlapping edge 11 is an extended channel. This makes the effects of accelerating drainage flow, interception, and blocking more prominent and effective.

[0037] like Figure 3 As shown, the inner surface of the large cover 5 is formed with several radially distributed guide ribs 52, which are beneficial for the annular drainage channel to guide and rectify the water flow, and further facilitate the drainage flow rate.

[0038] like Figure 2As shown, the bouncing core 2 includes an inner core 21 and an outer shell 22 that bounces vertically and vertically connected to the inner core 21. The lower end of the base 1 is provided with a water outlet 122, a connecting arm 123 located on the water outlet 122, and a mounting seat 124 located on the connecting arm 123. The inner core 21 is mounted on the mounting seat 124. The outer diameter of the inner core 21 is smaller than the outer diameter of the outer shell 22. In this invention, the inner core 21 serves as the connecting end to the base 1. Therefore, the mounting seat 124 used to mount the inner core 21 occupies less drainage area of ​​the water outlet 122 compared to existing technologies. Combined with the arm-like structure of the connecting arm 123, the drainage area formed by the water outlet 122 is larger. Together with the extended flow channel, this ensures that the new type of sink drain has a large drainage volume and efficiency.

[0039] like Figure 2 As shown, a connecting seat 6 is inverted at the upper end of the spring core 2, and the filter screen 3 is located on the connecting seat 6. When cleaning the filter screen 3, simply remove the connecting seat 6 from the seat body 1. In use, the large cover 5 and the connecting seat 6 can be disassembled separately in sequence, or the large cover 5 and the connecting seat 6 can be removed from the drain together, and then the large cover 5 and the connecting seat 6 can be separated as needed for easy cleaning.

[0040] like Figure 2 As shown, a connecting seat 6 is inverted on the upper end of the spring-loaded core 2, and a sealing element 4 is provided on the connecting seat 6. The large cover 5 is engaged with the connecting seat 6. When the large cover 5 is pressed, the connecting seat 6 and the sealing element 4 move with the spring-loaded core 2, and the sealing element 4 switches between a first position and a second position, realizing the opening or closing operation of the drain. When both the filter screen 3 and the sealing element 4 are provided on the connecting seat 6, the filter screen 3 is arranged on top and the sealing element 4 is on the bottom.

[0041] Of course, the seal 4 can also be directly installed on the outer periphery of the spring core 2, which can also switch between the first position and the second position as the spring core 2 moves. Under normal circumstances, when the large cover or connecting seat and its filter screen are disassembled and cleaned, the seal 4 remains on the spring core 2 and does not need to be disassembled.

[0042] like Figure 4 This is Embodiment 2 of the new type of sink drainer. The difference from Embodiment 1 is that the main body of the drainer base 1 located at the center of the overlapping edge 11 can have different structural shapes to adapt to the drainage connection of different sinks.
