[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 7 As shown, this utility model provides a drain device, including a base 1 and a sealing member 2. The base 1 has a flow hole 11, and the sealing member 2 is movably connected to the base 1. The sealing member 2 has a receiving cavity 211 configured to hold a cleaning agent. The outer peripheral wall of the sealing member 2 has a sealing part 221 and a through hole 222 communicating with the receiving cavity 211. When the sealing member 2 closes the flow hole 11, the sealing part 221 abuts against the inner wall of the flow hole 11, and the through hole 222 is closed. When the sealing member 2 is opened relative to the flow hole 11, the through hole 222 is opened.

[0041] In this invention, when the sealing member 2 closes the flow hole 11 through the sealing part 221, the through hole 222 is closed, which can ensure that the cleaning agent in the accommodating cavity 211 does not leak out and extend its service life. When the sealing member 2 opens the flow hole 11, the through hole 222 opens, and the water flows through the through hole 222 through the accommodating cavity 211 to dissolve the solid cleaning agent to form an aqueous solution, and flows out through the through hole 222 to the outer peripheral wall of the sealing member 2. The aqueous solution can remain on the outer peripheral wall of the sealing member 2 for a long time to clean the outer peripheral wall of the sealing member 2.

[0042] Specifically, the cleaning agent is solid, which facilitates long-term dissolution. In this embodiment, the cleaning agent can be a scale inhibitor. In this case, water flows through the through-hole 222 through the receiving cavity 211 to dissolve the solid scale inhibitor into an aqueous solution, and flows out through the through-hole 222 to the outer peripheral wall of the sealing member 2. The aqueous solution can remain on the outer peripheral wall of the sealing member 2 for a long time, forming a protective film layer, effectively inhibiting the formation and adhesion of scale crystals, avoiding the formation of scale that affects the sealing performance of the sealing part 221, so that the sealing member 2 can be smoothly adjusted relative to the seat 1, and reliably sealing the flow hole 11.

[0043] In one embodiment, the cleaning agent can be a deodorizer, descaling agent, disinfectant, or other solid cleaning products. When the cleaning agent is a deodorizer, water flows through the through hole 222 through the receiving cavity 211 to dissolve the solid deodorizer and form an aqueous solution. The aqueous solution then flows out through the through hole 222 to the outer peripheral wall of the sealing member 2. The aqueous solution can remain on the outer peripheral wall of the sealing member 2 for a long time, thereby achieving the purpose of deodorization.

[0044] In another embodiment, the cleaning agent may also be a mixture of at least two solid cleaning products. For example, the cleaning agent may be a mixture of a scale inhibitor and a deodorizer, which can both prevent the formation of scale and eliminate odors.

[0045] Specifically, the sealing component 2 includes a plate 21 and an elastic sleeve 22. A receiving cavity 211 is disposed on the plate 21, the elastic sleeve 22 is fitted over the outside of the plate 21, and a sealing part 221 and a through hole 222 are disposed on the elastic sleeve 22. Based on the plate 21, the elastic sleeve 22 allows the sealing part 221 to seal more reliably and the through hole 222 to be closed more reliably.

[0046] More specifically, the plate 21 is also provided with a connecting port 212 that communicates with the accommodating cavity 211. The cross-sectional area of ​​the connecting port 212 is larger than the cross-sectional area of ​​the through hole 222. The accommodating cavity 211 is connected to the through hole 222 through the connecting port 212. The above arrangement makes the assembly of the plate 21 and the elastic sleeve 22 simpler, eliminating the need to align the through hole 222 with the connecting port 212.

[0047] More specifically, the connecting opening 212 is an elongated hole, and the length direction of the connecting opening 212 is arranged along the circumferential direction of the outer peripheral wall of the plate 21. The above arrangement further reduces the assembly difficulty of the plate 21 and the elastic sleeve 22.

[0048] In this embodiment, the plate 21 is a circular plate, the connecting port 212 is provided on the outer peripheral wall of the plate 21, the elastic sleeve 22 is made of silicone and covers at least the outer periphery of the plate 21, and the sealing part 221 is an annular protrusion provided on the outer peripheral wall of the elastic sleeve 22. When the sealing part 221 abuts against the inner wall of the flow hole 11 in the circumferential direction, the sealing member 2 closes the flow hole 11.

[0049] Specifically, the outer peripheral wall of the plate 21 and / or the inner peripheral wall of the elastic sleeve 22 corresponding to the sealing part 221 are provided with an annular groove 213. The plate 21 and the elastic sleeve 22 form an annular connecting cavity 23 at the annular groove 213, and the connecting port 212 is connected to the through hole 222 through the annular connecting cavity 23. By providing the annular connecting cavity 23, space is provided for the deformation of the elastic sleeve 22, making the sealing of the sealing part 221 more reliable, and further reducing the assembly difficulty of the plate 21 and the elastic sleeve 22.

[0050] More specifically, the outer peripheral wall of the plate 21 is provided with an annular groove 213, and the connecting port 212 is provided at the bottom of the annular groove 213. The elastic sleeve 22 is provided with an annular protrusion 223 corresponding to the inner peripheral wall of the sealing part 221. An annular connecting cavity 23 is formed between the annular protrusion 223 and the annular groove 213. The annular protrusion 223 and the annular groove 213 cooperate to make the axial alignment and assembly of the plate 21 and the elastic sleeve 22 more precise.

[0051] Specifically, the plate surface of the plate 21 and the inner wall of the elastic outer sleeve 22 are provided with a positioning ring groove 214 and a positioning protrusion 224, respectively, which extends into the positioning ring groove 214. The positioning protrusion 224 and the positioning ring groove 214 cooperate to make the radial alignment and assembly of the plate 21 and the elastic outer sleeve 22 more precise.

[0052] More specifically, the two sides of the plate 21 are respectively provided with positioning ring grooves 214, and the inner wall of the elastic outer sleeve 22 is provided with two positioning protrusions 224, which extend into the two positioning ring grooves 214 in a corresponding manner.

[0053] In this embodiment, the projection of the through hole 222 on the plate 21 along the axial direction does not overlap with the connecting port 212, thereby preventing water from flowing directly through the through hole 222 to the detergent in the receiving cavity 211, reducing the consumption rate of the detergent, and allowing the water to slowly flow through the through hole 222, the annular connecting cavity 23 and the connecting port 212 in sequence before flowing into the receiving cavity 211 to dissolve the detergent and form an aqueous solution. Furthermore, the aqueous solution can slowly flow out through the through hole 222 after passing through the connecting port 212 and the annular connecting cavity 23 in sequence, and remain on the outer peripheral wall of the sealing member 2 for a long time.

[0054] Specifically, when the sealing component 2 closes the flow hole 11, the elastic sleeve 22 elastically deforms to close the through hole 222. This configuration makes the closure of the through hole 222 more stable and reliable.

[0055] More specifically, two sets of through holes 222 are provided, with the sealing part 221 located between the two sets of through holes 222 along the thickness direction of the sealing member 2. Multiple through holes 222 in each set are evenly distributed on the outer peripheral wall of the sealing member 2. This arrangement allows the aqueous solution to flow through the through holes 222 to multiple locations on the outer peripheral wall of the sealing member 2, spreading from both sides towards the sealing part 221, thus providing more comprehensive coverage of the outer peripheral wall of the sealing member 2.

[0056] More specifically, the sealing element 2 is rotatably connected to the base 1, with its rotation axis parallel to the radial direction of the flow hole 11. This configuration makes the opening and closing of the sealing element 2 more convenient.

[0057] In this embodiment, each group of through holes 222 is provided with six holes, and the six through holes 222 in each group are evenly distributed on the outer peripheral wall of the sealing member 2. The rotation axis of the sealing member 2 is located on the symmetrical plane of two adjacent through holes 222, and the multiple through holes 222 in the two groups are arranged facing each other in the axial direction of the sealing member 2.

[0058] In other embodiments, each group of through holes 222 may be provided with other numbers, and the multiple through holes 222 in the two groups may be staggered in the axial direction of the sealing member 2. The closure of the through holes 222 may also be achieved by the abutment of the inner wall of the flow hole 11.

[0059] In this embodiment, the drain is a flip-top drain. A rotating shaft is provided between the plate 21 and the base 1. The rotating shaft is rotatably connected to the plate 21 and / or the base 1. The aperture of the through hole 222 is small, forming a micro-permeable hole. When the sealing member 2 rotates to the closed state to close the flow hole 11, the sealing part 221 abuts against the inner wall of the flow hole 11. The elastic sleeve 22 deforms to close the through hole 222, preventing water from seeping into the accommodating cavity 211 through the hole 222 and blocking the vertical water flow from penetrating through the flow hole 11. When the sealing member 2 rotates to the open state to open the flow hole 11, the water flows through the through hole 222 into the accommodating cavity 211 and reacts with the scale inhibitor to generate an aqueous solution with scale inhibitory properties. When the faucet is closed, the treated aqueous solution can remain in the sealing interface area of ​​the outer peripheral wall of the sealing member 2 for a long time. Its scale inhibitory components can form a protective film layer in the sealing interface area, effectively inhibiting the formation and adhesion of scale crystals.

[0060] In other embodiments, the sealing element 2 is adjustablely connected to the seat 1 along the axial direction of the flow hole 11, and the drain is a pop-up drain or a pull-up drain. The specific connection structure and adjustment method of the sealing element 2 in the pop-up drain or the pull-up drain are existing technologies and will not be described in detail here.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
