[0039] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0040] As Figures 1 to 7 shown, the present invention provides a drainer, which includes a base body 1 and a plugging member 2. Among them, the base body 1 is provided with a circulation hole 11, the plugging member 2 is movably connected to the base body 1, a receiving cavity 211 is provided in the plugging member 2, the receiving cavity 211 is configured to receive a cleaning agent, a sealing portion 221 and a through hole 222 communicating with the receiving cavity 211 are provided on the outer peripheral wall of the plugging member 2. When the plugging member 2 closes the circulation hole 11, the sealing portion 221 abuts against the inner wall of the circulation hole 11, and the through hole 222 is closed. When the plugging member 2 is opened relative to the circulation hole 11, the through hole 222 is opened.

[0041] In the present invention, when the plugging member 2 closes the circulation hole 11 through the sealing portion 221, the through hole 222 is closed, which can ensure that the cleaning agent in the receiving cavity 211 does not flow out, prolonging the service life. When the plugging member 2 opens the circulation hole 11, the through hole 222 is opened, and water flows through the through hole 222 through the receiving cavity 211 to dissolve the solid cleaning agent to form an aqueous solution, and flows out to the outer peripheral wall of the plugging member 2 through the through hole 222. The aqueous solution can stay on the outer peripheral wall of the plugging member 2 for a long time to clean the outer peripheral wall of the plugging member 2.

[0042] Specifically, the cleaning agent is a solid, which is convenient for long-term dissolution. In this embodiment, the cleaning agent can be a scale inhibitor. At this time, water flows through the through hole 222 through the receiving cavity 211 to dissolve the solid scale inhibitor to form an aqueous solution, and flows out to the outer peripheral wall of the plugging member 2 through the through hole 222. The aqueous solution can stay on the outer peripheral wall of the plugging member 2 for a long time to form a protective film layer, effectively inhibiting the generation and attachment of scale crystals, avoiding the formation of scale and affecting the sealing performance of the sealing portion 221, so that the plugging member 2 can be smoothly adjusted relative to the base body 1 and reliably close the circulation hole 11.

[0043] In another embodiment, the cleaning agent can be other solid cleaning products such as deodorant, descaling agent, disinfectant, etc. When the cleaning agent is a deodorant, water flows through the through hole 222 through the receiving cavity 211 to dissolve the solid deodorant to form an aqueous solution, and flows out to the outer peripheral wall of the plugging member 2 through the through hole 222. The aqueous solution can stay on the outer peripheral wall of the plugging member 2 for a long time to achieve the purpose of deodorization.

[0044] In another embodiment, the cleaning agent can also be a mixture of at least two solid cleaning products. For example, the cleaning agent can be a mixture of a scale inhibitor and a deodorant, which can not only prevent the formation of scale but also eliminate odors.

[0045] Specifically, the plugging member 2 includes a plate body 21 and an elastic outer sleeve 22. Among them, a receiving cavity 211 is provided in the plate body 21, the elastic outer sleeve 22 is sleeved outside the plate body 21, and a sealing portion 221 and a through hole 222 are provided in the elastic outer sleeve 22. Based on the plate body 21, by providing the elastic outer sleeve 22, the sealing portion 221 can seal more reliably, and the through hole 222 can be closed more reliably.

[0046] More specifically, a communication port 212 communicating with the receiving cavity 211 is further provided on the plate body 21. The cross-sectional area of the communication port 212 is larger than that of the through hole 222, and the receiving cavity 211 communicates with the through hole 222 through the communication port 212. With the above settings, the assembly of the plate body 21 and the elastic outer sleeve 22 is simpler, and there is no need to align the through hole 222 with the communication port 212.

[0047] More specifically, the communication port 212 is a long strip hole, and the length direction of the communication port 212 is arranged along the circumferential direction of the outer peripheral wall of the plate body 21. With the above settings, the assembly difficulty of the plate body 21 and the elastic outer sleeve 22 is further reduced.

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

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

[0050] More specifically, an annular groove 213 is provided on the outer peripheral wall of the plate body 21, the communication port 212 is provided at the bottom of the annular groove 213, and an annular rib 223 is provided on the inner peripheral wall of the elastic outer sleeve 22 corresponding to the sealing portion 221. An annular communication cavity 23 is formed between the annular rib 223 and the annular groove 213. The cooperation of the annular rib 223 and the annular groove 213 makes the axial alignment assembly of the plate body 21 and the elastic outer sleeve 22 more accurate.

[0051] Specifically, one of the plate surface of the plate body 21 and the inner wall of the elastic outer sleeve 22 is provided with a positioning ring groove 214, and the other is provided with a positioning rib 224. The positioning rib 224 extends into the positioning ring groove 214. The cooperation between the positioning rib 224 and the positioning ring groove 214 makes the radial alignment and assembly of the plate body 21 and the elastic outer sleeve 22 more precise.

[0052] More specifically, positioning ring grooves 214 are respectively provided on both side plate surfaces of the plate body 21, and two positioning ribs 224 are provided on the inner wall of the elastic outer sleeve 22. The two positioning ribs 224 respectively extend into the two positioning ring grooves 214 in a one-to-one correspondence.

[0053] In this embodiment, the projection of the through hole 222 on the plate body 21 along the axial direction does not overlap with the communication port 212, so that the water flow can be prevented from directly flushing the cleaning agent in the accommodating cavity 211 through the through hole 222, reducing the consumption speed of the cleaning agent. The water flow slowly passes through the through hole 222, the annular communication cavity 23, and the communication port 212 in sequence and then flows into the accommodating cavity 211 to dissolve the cleaning agent to form an aqueous solution. And the aqueous solution can slowly flow out through the through hole 222 after passing through the communication port 212 and the annular communication cavity 23 in sequence, and stays on the outer peripheral wall of the plugging member 2 for a long time.

[0054] Specifically, when the plugging member 2 closes the flow hole 11, the elastic outer sleeve 22 elastically deforms to close the through hole 222. The above setting makes the closing of the through hole 222 more stable and reliable.

[0055] More specifically, there are two groups of through holes 222. In the thickness direction of the plugging member 2, the sealing portion 221 is located between the two groups of through holes 222. The multiple through holes 222 in each group are evenly distributed on the outer peripheral wall of the plugging member 2. The above setting enables the aqueous solution to flow to multiple positions on the outer peripheral wall of the plugging member 2 through the through holes 222, spread from both sides to the sealing portion 221, and cover the outer peripheral wall of the plugging member 2 more comprehensively.

[0056] More specifically, the plugging member 2 is rotatably connected to the seat body 1, and the rotation axis is parallel to the radial direction of the flow hole 11. The above setting makes the opening and closing of the plugging member 2 more convenient.

[0057] In this embodiment, each group of through holes 222 is provided with six. The six through holes 222 in each group are evenly distributed on the outer peripheral wall of the plugging member 2. The rotation axis of the plugging member 2 is located in the symmetry plane of two adjacent through holes 222. The multiple through holes 222 in the two groups are arranged in a one-to-one correspondence in the axial direction of the plugging member 2.

[0058] In other embodiments, each group of through holes 222 can also be provided with other numbers, the multiple through holes 222 in the two groups can also be arranged in a staggered manner in the axial direction of the plugging member 2, and the closing of the through hole 222 can also be achieved by the abutment of the inner wall of the flow hole 11.

[0059] In this embodiment, the drainer is a flip-up drainer. A rotating shaft is provided between the plate body 21 and the base body 1, and the rotating shaft is rotatably connected to the plate body 21 and / or the base body 1. The aperture of the through hole 222 is small to form a micro-permeation hole. When the plug 2 rotates to the closed state to seal the flow hole 11, the sealing portion 221 abuts against the inner wall of the flow hole 11, and the elastic outer sleeve 22 deforms to close the through hole 222, preventing water from seeping into the accommodating cavity 211 through the through hole 222 and blocking the vertical water flow from penetrating through the flow hole 11. When the plug 2 rotates to the open state to open the flow hole 11, the water enters the accommodating cavity 211 through the through hole 222 and contacts the scale inhibitor to generate an aqueous solution with scale-inhibiting properties. When the faucet is in the closed state, the treated aqueous solution can stay in the sealing interface area of the outer peripheral wall of the plug 2 for a long time, and its scale-inhibiting components can form a protective film layer in the sealing interface area, effectively inhibiting the generation and attachment of scale crystals.

[0060] In other embodiments, the plug 2 is adjustably connected to the base body 1 along the axial direction of the flow hole 11. The drainer is a pop-up drainer or a lift-up drainer. The specific connection structure and adjustment method of the plug 2 in the pop-up drainer or the lift-up drainer are prior arts and will not be elaborated here.

[0061] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
