Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a filtering structure, a floor drain, a strainer, a draining basket and a sink filter. Background Art

[0002] In modern family life, the sink in the kitchen is an important facility for washing vegetables, fruits and tableware. In order to prevent solid wastes such as fruit and vegetable peels and food residues falling during the washing process from entering the sewer and causing blockage, people usually install a filter at the drain outlet of the sink to intercept the solid wastes.

[0003] The structures of many existing filters are similar to those shown in Chinese patents CN219879293U and CN213390395U. When in use, they have the following inconveniences: 1. The lifting rod and the handle for lifting are surrounded by solid wastes, and it is easy to get hands dirty when extracting; 2. When removing solid wastes, it is necessary to turn it over for dumping, which is rather troublesome, and it is inconvenient to take when turning it over; 3. Hindered by the lifting rod and the handle, it is not easy to clean the inside of the filter. When cleaning, it is necessary to turn it over and rinse it in the reverse direction to flush out the residues, and the operation is troublesome; 4. Solid wastes are easily stuck in the filtering holes and are not easy to take out.

[0004] Similar to the sink filter, the floor drain in the bathroom also has the functions of draining water and intercepting solid wastes. However, different from the sink filter, the solid wastes intercepted by the floor drain are mostly slender solid wastes such as fibers and hairs, and such solid wastes also have the problem of being easily entangled on the floor drain and not easy to clean.

DETAILED DESCRIPTION

[0041] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Embodiment 1

[0043] like Figures 1-9 As shown, the utility model discloses a filtering structure, comprising a first filter element 1 and a second filter element 2 which are rotatably connected, and the first filter element 1 and the second filter element 2 are switched between a spliced ​​state and an open state through relative rotation.

[0044] In the assembled state, the first filter element 1 and the second filter element 2 approach and fit together under the influence of their own weights. After fitting, the overall shape of the first filter element 1 and the second filter element 2 is cylindrical, bowl-shaped, basin-shaped, etc. A filter cavity 3 with an open top is formed by surrounding between the first filter element 1 and the second filter element 2, and the bottom and / or side of the filter cavity 3 has a plurality of filter through-holes 31. That is to say, in the assembled state, the first filter element 1 and the second filter element 2 cooperate to have a filtering function, allowing fluids to pass through and intercepting solids.

[0045] In the open state, the joint between the first filter element 1 and the second filter element 2 is separated from each other, and an opening is formed between the bottoms of the first filter element 1 and the second filter element 2. The position of this opening corresponds to the position of the bottom of the filter cavity bottom 3 in the assembled state. In the open state, the intercepted solids can directly fall through the bottom opening, achieving the purpose of quickly removing the solids. During the removal process, the hand is not easily in contact with the intercepted solids, and it is convenient to rinse after the solids are removed.

[0046] In this embodiment, two first connection parts 11 are oppositely arranged on the upper part of the first filter element 1, and two second connection parts 21 are oppositely arranged on the upper part of the second filter element 2. The first filter element 1 and the second filter element 2 are oppositely arranged, and the first connection part 11 and the second connection part 22 thereon are rotatably connected along the horizontal direction.

[0047] The above-mentioned filter through-holes 31 can be completely opened on the first filter element 1 and the second filter element 2, or can be formed by the fitting of the first filter element 1 and the second filter element 2. As one of the cases, a plurality of first comb teeth 12 can extend from the bottom of the first filter element 1 towards the second filter element 2. Each of the first comb teeth 12 is parallel and spaced. Corresponding grooves or other structures are provided on the second filter element 2 so that the second filter element 2 in the assembled state can avoid the first comb teeth 12 on the first filter element 1. At the same time, in the assembled state, at least one of the above-mentioned filter through-holes 31 is formed by the side walls of the first comb teeth 12 and the side walls of the second filter element 2 surrounding each other.

[0048] Such filter through-holes 31 formed by the surrounding of the first comb teeth 12 and the second filter element 2 can play a filtering role in the assembled state of the first filter element 1 and the second filter element 2. In the open state, the interception effect on solids is greatly reduced, so that the solids originally intercepted in the filter cavity 3 can directly fall and be taken out, and are not easily stuck in the pores. Moreover, even if the intercepted solids are long and thin and intertwined with each other, they can be directly combed down, and the cleaning is convenient.

[0049] Preferably, the bottom of the second filter element 2 extends toward the first filter element 1 to form a plurality of second comb teeth 22, and the second comb teeth 22 are parallel and spaced apart. The structure of the second comb teeth 22 is similar to that of the first comb teeth 12, and the two are arranged in an interlaced manner. In the assembled state, the first comb teeth 12 and the second comb teeth 22 are interlaced with each other, and at least one filter through hole 31 is formed by the side wall of the first comb teeth 12 and the side wall of the second comb teeth 22. The filter through hole 31 formed by the encirclement is small, which is convenient for filtering small-sized solids.

[0050] In order to conveniently control the opening and closing of the first filter element 1 and the second filter element 2 to switch between the spliced ​​state and the open state, as shown in FIG. Figure 10 As shown, the top of the first filter element 1 extends upward to form an opening and closing paddle 13, which is located on the side of the first connecting portion 11. By turning the opening and closing paddle 13, the first filter element 1 can be driven to rotate, thereby adjusting the opening and closing degree, and the adjustment can be operated with one hand.

[0051] In addition to the opening and closing paddle 13, a first kneading portion 14 may be extended upward from the top of the first filter element 1, and a second kneading portion 23 may be extended upward from the top of the second filter element 2. The first kneading portion 14 is located between the two first connecting portions 11, and the second kneading portion 23 is located between the two second connecting portions 21, and the position corresponds to the first kneading portion 14. By kneading the first kneading portion 14 and the second kneading portion 23 to bring them closer to each other, the first filter element 1 and the second filter element 2 can be driven to rotate relative to each other and switch them to an open state. Conversely, by pushing the first kneading portion 14 and the second kneading portion 23 away from each other, the first filter element 1 and the second filter element 2 can be rotated to be spliced ​​together and switched to a spliced ​​state. In addition to the switching state, the first kneading portion 14, the second kneading portion 23 and the above-mentioned opening and closing paddle 13 can also serve as handles to facilitate the removal and placement of the filter structure.

[0052] The first filter element 1 and the second filter element 2 are rotatably connected via a rotating shaft 4, that is, the first connecting portion 11 and the second connecting portion 21 are rotatably connected via a rotating shaft 4. The rotating shaft 4 can be independently provided for easy disassembly, or can be integrally formed with the first connecting portion 11 or the second connecting portion 21.

[0053] Furthermore, Figure 11 As shown, a torsion spring 5 is sleeved horizontally on the outer side of the rotating shaft 4, and the two ends of the torsion spring 5 respectively abut against the first connecting portion 11 and the second connecting portion 21. Under the action of the torsion spring 5, the horizontal splicing state of the first filter element 1 and the second filter element 2 can be maintained until they are separated by an external force. When the first filter element 1 or the second filter element 2 is manually rotated to convert it to an open state, the torsion spring 5 can store energy to provide power for the automatic reset of the first filter element 1 and the second filter element 2, and turn the first filter element 1 and the second filter element 2 back to the splicing state after the external force is removed.

[0054] In addition to adding a torsion spring 5, the combined state of the first filter element 1 and the second filter element 2 can also be better maintained by magnetic attraction. As Figures 12-13 shown, the first filter element 1 has a first mating surface 15, and the second filter element 2 has a second mating surface 24. Magnets 6 are embedded on both the first mating surface 15 and the second mating surface 24. In the combined state, the first mating surface 15 and the second mating surface 24 are in close contact with each other, and the magnets 6 on the first mating surface 15 and the magnets 6 on the second mating surface 24 can attract each other to maintain the combined state.

[0055] For convenient installation, a first support step 16 extends outward from the upper part of the first filter element 1, and a second support step 25 extends outward from the upper part of the second filter element 2. Both the first support step 16 and the second support step 25 are semi-circular, and their bottom end faces are usually flush. The stable installation of the filter structure can be achieved through the outwardly protruding first support step 16 and the second support step 25.

[0056] The above-mentioned first connecting portion 11 is correspondingly arranged at both ends of the first support step 16, and the second connecting portion 21 is correspondingly arranged near both ends of the second support step 25. By changing the shapes of the first connecting portion 11 and the second connecting portion 21, changing the position of the opening and closing flap 13, etc., the rotation angle and the stop position of the first filter element 1 and the second filter element 2 can be correspondingly set.

[0057] Embodiment 2

[0058] On the basis of the above Embodiment 1, the present utility model also discloses a sink filter, including the above-mentioned filter structure. When this sink filter is used for a sink, it can be directly snapped in and horizontally installed at the drain outlet of the sink, or can be used in cooperation with fixed collars of different inner diameters, so as to intercept solid substances such as food residues and fruit and vegetable peels.

[0059] Embodiment 3

[0060] On the basis of the above Embodiment 1, the present utility model also discloses a floor drain, including the above-mentioned filter structure. As Figures 14-16 shown, since there are usually more hairs and fiber substances on the ground, the first filter element 1 and the second filter element 2 in this floor drain are preferably provided with a first comb tooth 12 and a second comb tooth 22, and substantially all the filter through holes 31 are formed by the side walls of the first comb tooth 12 and the side walls of the second comb tooth 22, which is convenient for removing the intercepted slender solid substances. The overall floor drain can be flat to be installed above the drain pipe, or can be cylindrical to be partially inserted into the drain pipe and used in cooperation with a floor drain cover.

[0061] Embodiment 4

[0062] On the basis of the above Embodiment 1, asFigure 17 , 18 As shown, the utility model also discloses a drain basket, including the above-mentioned filter structure and a liquid holding basin 7. The above-mentioned first support step 16 and the second support step 25 are detachably clamped on the upper edge of the liquid holding basin 7, and then the first filter element 1 and the second filter element 2 are mounted in the liquid holding basin 7. The liquid holding basin 7 can receive clean water for washing and intercept sewage flowing through the filter through hole 31. Similar to the floor drain, the filter through hole 31 in the drain basket is basically formed by the side wall of the first comb tooth 12 and the side wall of the second comb tooth 22. When the first filter element 1 and the second filter element 2 are completely assembled, there is basically no gap between the two, which is convenient for soaking and cleaning. When the first filter element 1 and the second filter element 2 are partially assembled, the filter through hole 31 can be formed to filter out sewage.

[0063] Embodiment 5

[0064] Based on the above embodiment 1, Figure 19 As shown, the utility model also discloses a colander, including the above-mentioned filtering structure and a hand-held handle 8. One end of the hand-held handle 8 is fixedly connected to the outside of the first filter element 1, and an adjusting rotating rod 9 is installed in the hand-held handle 8. One end of the adjusting rotating rod 9 is fixedly connected to the second filter element 2, and can rotate coaxially with the second filter element 2, that is, it is coaxially arranged with the above-mentioned rotating shaft 4. By rotating the adjusting rotating rod 9, the second filter element 2 can be driven to rotate, thereby controlling the opening and closing of the filtering structure to switch the state. When controlling the opening and closing, the hand does not need to be turned over, nor does it need to be close to the first filter element 1 and the second filter element 2, and the operation is convenient. On this basis, the middle part of the adjusting rotating rod 9 is also protrudingly provided with a toggle portion 91, and the adjusting rotating rod 9 can be rotated by the toggle portion 91 to improve the convenience of opening and closing control.
