Description

Technical Field

[0001] This utility model relates to the field of drainers, specifically to a drainer that facilitates the removal of the filter basket. Background Technology

[0002] Hair and other debris often fall into the drain of a sink, and over time, this mixture of hair and debris can clog the drain pipe and drain cylinder. Therefore, a filter basket is needed for collection and cleaning. However, because the filter basket is located inside the drain outlet and has a water storage and drainage switching structure at the top, the filter basket of existing drainers on the market is not easy to remove.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0004] The main purpose of this utility model is to provide a drain device that facilitates the removal of the filter basket, thereby solving the problem of inconvenient removal of the filter basket mentioned in the background art.

[0005] To achieve the above objectives, the solution of this utility model is: A drain device for easy removal of a filter basket includes a drain cylinder, a water storage / drainage switching structure, and a filter basket. The drain cylinder has an opening, and the filter basket is inserted into the inner cavity of the drain cylinder through the opening. The water storage / drainage switching structure is detachably mounted at the opening of the drain cylinder above the filter basket. A water-passing bracket is provided below the filter basket. The water-passing bracket is connected to the inner wall of the drain cylinder, and a lifting mechanism is provided between the filter basket and the water-passing bracket to lift the filter basket from a low position to a high position. When the water storage / drainage switching structure is installed, the filter basket is in a low position and the top of the filter basket abuts against the water storage / drainage switching structure. When the water storage / drainage switching structure is disassembled, the filter basket moves upward from the low position to the high position.

[0006] Furthermore, the lifting mechanism is disposed between the bottom of the filter basket and the water-passing bracket.

[0007] Furthermore, a first mounting seat with an upward opening is formed in the center of the water-passing bracket, and a second mounting seat with a downward opening is formed in the center of the bottom of the filter basket; the lifting mechanism is installed between the first mounting seat and the second mounting seat.

[0008] Furthermore, the filter basket is composed of a first basket and a second basket distributed on the left and right sides, and the first basket and the second basket can be separated when cleaning the filter basket.

[0009] Furthermore, the inner wall of the lower water cylinder is formed with internal threads, and the water-passing bracket is threadedly connected to the internal threads.

[0010] Furthermore, the water storage and drainage switching structure includes an outer ring body and a flip cover. The outer ring body is detachably installed at the opening of the drain cylinder, and the flip cover is rotatably located inside the outer ring body to switch between water sealing and drainage. A first sealing ring is provided on the outer wall of the outer ring body, and the outer ring body abuts against the inner wall of the drain cylinder body through the first sealing ring.

[0011] Furthermore, a limiting step is formed on the inner wall of the lower cylinder for the filter basket to overlap; the upper edge of the filter basket is located between the limiting step and the outer ring; and a handle is provided at the upper end of the filter basket.

[0012] Furthermore, a settling groove is provided at the upper end of the opening of the drain cylinder, and the outer peripheral edge of the outer ring body is embedded in the settling groove.

[0013] Furthermore, the lifting mechanism includes a first magnet mounted on the water-passing bracket and a second magnet formed on the filter basket, the first magnet and the second magnet repelling each other.

[0014] Furthermore, the lifting mechanism includes a spring, the upper end of which abuts against the filter basket, and the lower end of which abuts against the water-passing bracket; One end of the spring is a fixed end, and the other end is a movable abutment end; the lower end of the spring is fixed to the water-passing bracket, and the upper end can be detached from the filter basket; or, the upper end of the spring is fixed to the filter basket, and the lower end can be detached from the water-passing bracket.

[0015] With the above structure, the drain device of this utility model that facilitates the removal of the filter basket has at least the following beneficial effects: 1. When it is necessary to remove the filter basket, first remove the water storage and drainage switching structure; since the upper end of the filter basket is no longer limited by the water storage and drainage switching structure, the filter basket is pushed upward to a high position under the drive of the lifting mechanism, which makes it convenient for the user to pick up and remove the filter basket for cleaning.

[0016] After cleaning, the filter basket is put back, and then the water storage and drainage switching structure is reinstalled at the opening of the drain cylinder. During this process, the water storage and drainage switching structure presses down on the filter basket, causing the filter basket to move from a high position to a low position. The lifting mechanism continues to accumulate force to prepare for the next lifting of the filter basket.

[0017] 2. The friction between the outer ring of the water storage / drainage switching structure and the opening of the drain cylinder primarily resists the upward lifting force of the filter basket, ensuring a stable connection between the water storage / drainage switching structure and the drain cylinder. A detachable snap-fit ​​structure can also be used between the outer ring and the drain cylinder to limit the axial position of the installed outer ring.

[0018] 3. The lifting mechanism can be a magnetic repulsion mechanism or a spring-spring lifting mechanism. The downward movement of the filter basket is to accumulate energy, and the filter basket is lifted upward after the water storage and drainage switching structure is disassembled.

[0019] Compared with the prior art, this utility model has a lifting mechanism that allows the filter basket to be lifted a certain distance after the water storage and drainage switching structure is removed, making it convenient for users to take the filter basket. Attached Figure Description

[0034] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0035] like Figures 1 to 13 As shown, this utility model relates to a drain device that facilitates the removal of the filter basket, comprising a drain cylinder 1, a water storage and drainage switching structure 2, and a filter basket 3; the drain cylinder 1 has an opening 12, and the filter basket 3 is inserted into the inner cavity of the drain cylinder 1 through the opening 12; the water storage and drainage switching structure 2 is detachably disposed above the filter basket 3 at the opening 12 of the drain cylinder 1; a water-passing bracket 4 is disposed below the filter basket 3; the water-passing bracket 4 is connected to the inner wall of the drain cylinder 1, and a lifting mechanism 5 is provided between the filter basket 3 and the water-passing bracket 4 for lifting the filter basket 3 from a low position to a high position; when the water storage and drainage switching structure 2 is installed, the filter basket 3 is in a low position and the top of the filter basket 3 abuts against the water storage and drainage switching structure 2; when the water storage and drainage switching structure 2 is disassembled, the filter basket 3 moves upward from the low position to the high position.

[0036] Thus, the drain device of this utility model that facilitates the removal of the filter basket allows the user to first remove the water storage and drainage switching structure 2 when the filter basket 3 needs to be removed. Since the upper end of the filter basket 3 is no longer limited by the water storage and drainage switching structure 2, the filter basket 3 is pushed upward to a high position under the drive of the lifting mechanism 5, making it convenient for the user to pick up and remove the filter basket 3 for cleaning.

[0037] After cleaning, the filter basket 3 is put back, and then the water storage and drainage switching structure 2 is installed back into the cylinder opening 12 of the drain cylinder 1. During this process, the water storage and drainage switching structure 2 presses down on the filter basket 3, causing the filter basket 3 to move from a high position to a low position. The lifting mechanism 5 continues to store force to prepare for the next lifting of the filter basket 3.

[0038] Preferably, the lifting mechanism 5 is disposed between the bottom of the filter basket 3 and the water-passing bracket 4. Specifically, the water-passing bracket 4 has a first mounting seat 541 with an upward opening at its center, and the filter basket 3 has a second mounting seat 542 with a downward opening at its bottom center; the lifting mechanism 5 is installed between the first mounting seat 541 and the second mounting seat 542.

[0039] Preferably, the filter basket 3 is composed of a first basket 31 and a second basket 32 ​​arranged on the left and right sides, and the first basket 31 and the second basket 32 ​​can be separated when cleaning the filter basket 3. The opening method can be that the left and right sides are completely separated (fixed to each other by magnetic attraction when assembled), or they can be opened by rotating around a rotation axis and opening up to each other (fixed to each other by magnetic attraction when assembled).

[0040] Preferably, such as Figure 5 As shown, the inner wall of the drain cylinder 1 has an internal thread 13, and the water-passing bracket 4 is threadedly connected to the internal thread 13. Alternatively, as shown... Figure 13 As shown, one end of the water-passing bracket 4 is integrally connected to the inner wall of the drain cylinder 1. Furthermore, for ease of processing, the drain cylinder 1 is divided into upper and lower parts with threaded connections.

[0041] Preferably, the water storage and drainage switching structure 2 includes an outer ring body 21 and a flip cover 22. The outer ring body 21 is detachably disposed at the opening 12 of the drain cylinder 1, and the flip cover 22 is rotatably located inside the outer ring body 21 to switch between water sealing and drainage. A first sealing ring 211 is provided on the outer wall of the outer ring body 21, and the outer ring body 21 abuts against the inner wall of the drain cylinder 1 through the first sealing ring 211.

[0042] The friction between the outer ring 21 of the water storage and drainage switching structure 2 and the opening 12 of the drain cylinder 1 mainly resists the upward lifting force of the filter basket 3, thus maintaining a stable connection between the water storage and drainage switching structure 2 and the drain cylinder 1. A detachable snap-fit ​​structure can also be used between the outer ring 21 and the drain cylinder 1 to limit the axial position of the installed outer ring 21.

[0043] like Figure 12 and Figure 13 As shown, the water storage and drainage switching structure 2 may also include an outer ring body 21, a spring switch 23 and a water sealing plate 24. The spring switch 23 is installed on the central frame of the outer ring body 21, and the water sealing plate 24 is set on the top of the spring switch 23.

[0044] Preferably, a limiting step 11 is formed on the inner wall of the drain cylinder 1 for the filter basket 3 to overlap; the upper edge of the filter basket 3 is located between the limiting step 11 and the outer ring 21; a handle 33 is provided at the upper end of the filter basket 3. The limiting step 11 restricts the lowest position of the filter basket 3, and the outer ring 21 and the limiting step 11 clamp each other, so that the filter basket 3 remains stable.

[0045] The handle 33 can be integrally formed on the filter basket 3, such as a lug formed on the upper end of the filter basket 3, or it can be a rotatable and foldable semi-circular handle (e.g. Figure 8 (As shown).

[0046] Preferably, a settling groove is provided at the upper end of the cylinder opening 12 of the drain cylinder 1, and the outer peripheral edge of the outer ring 21 is embedded in the settling groove.

[0047] The lifting mechanism 5 can be a magnetic repulsion mechanism or a spring 53 springing mechanism. The filter basket 3 moves downward to accumulate energy, and after the water storage and drainage switching structure 2 is disassembled, the filter basket 3 is lifted upward.

[0048] Specifically, the lifting mechanism 5 includes a first magnet 51 mounted on the water-passing bracket 4 and a second magnet 52 formed on the filter basket 3, the first magnet 51 and the second magnet 52 repelling each other. The magnetic force of the magnets causes the filter basket 3 to accumulate energy when pressed down, and when the outer ring 21 is removed, the magnetic repulsion force lifts the filter basket 3 upward.

[0049] Alternatively, the lifting mechanism 5 includes a spring 53, the upper end of which abuts against the filter basket 3, and the lower end of which abuts against the water-passing bracket 4; one end of the spring 53 is a fixed end, and the other end is a movable abutting end; the lower end of the spring 53 is fixed to the water-passing bracket 4, and the upper end is detachable from the filter basket 3; or, the upper end of the spring 53 is fixed to the filter basket 3, and the lower end is detachable from the water-passing bracket 4.

[0050] Compared with the prior art, this utility model has a lifting mechanism 5, which allows the filter basket 3 to be lifted up a certain distance after the water storage and drainage switching structure 2 is removed, making it convenient for users to take the filter basket 3.

[0051] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
