Description

Technical Field

[0001] This utility model relates to a quick-release floor drain. Background Technology

[0002] Floor drains are an important interface connecting the drainage pipe system to the indoor floor. As an important component of the residential drainage system, the quality of the filter cartridge's sealing directly affects the cleanliness of indoor air and environment, and is very important for controlling odors in kitchens and bathrooms.

[0003] In existing technologies, filter cartridges are often installed by placing them directly on the outlet of the drain housing. The filter cartridge is held in place by its own weight through the convex ring on top of the drain housing. However, this method does not involve a fastening structure for fixation. After prolonged use, the filter cartridge is prone to displacement and loosening, which can lead to water leakage and other problems that affect the normal use of the drain. Utility Model Content

[0004] This invention provides a quick-release floor drain that can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A quick-release floor drain includes a drain housing with an inlet and an outlet, a cover placed in the inlet, a filter screen embedded inside the drain housing, and a filter element installed at the bottom outlet; the filter element is screwed and locked inside the outlet of the drain housing, and the top periphery of the filter element has a rest portion that extends into the drain housing; when the cover and filter screen are removed from the drain housing, an operating cavity is formed inside the drain housing for a human hand to reach in and rotate to unlock the filter element.

[0007] As a further improvement, an annular stepped groove is formed on the bottom circumference of the drain housing for the mounting of the support part. The outlet is coaxially located in the middle of the annular stepped groove. The outer diameter of the filter element is smaller than the outer diameter of the outlet, and the outer diameter of the support part is larger than the outer diameter of the outlet. Two "L-shaped" locking members are symmetrically fixed on the outer wall of the filter element near the support part. The inner wall of the outlet protrudes inward to form two spaced arc-shaped segments. A clearance hole is formed between the opposite ends of the two arc-shaped segments to allow the arc-shaped segments to pass. The locking member includes a horizontal part extending along the axial direction of the filter element and a hook anchor part vertically fixed at the end of the horizontal part. A locking groove is formed between the horizontal part and the hook anchor part for the end of the arc-shaped segment to be engaged.

[0008] As a further improvement, two operating handles are symmetrically fixed at the top of the stop to facilitate rotating the stop.

[0009] As a further improvement, a sealing ring is embedded on the periphery of the filter element. When the filter element is screwed and locked inside the drain housing, one side of the sealing ring is pressed and sealed with the support part, and the other side is pressed and sealed with the bottom of the annular stepped groove.

[0010] The beneficial effects of this utility model are:

[0011] This application installs the filter element inside the drain housing's outlet by setting a support at the top of the filter element and using a screw-on locking method. Users only need to remove the cover and filter screen from inside the drain housing to directly disassemble and replace the filter element. It has the advantages of simple structure and convenient disassembly and assembly. Furthermore, since the filter element is locked inside the drain housing's outlet, it is not easy for it to shift during use, which is conducive to the long-term stable use of the overall drain structure.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5 As shown, a quick-release floor drain includes a floor drain housing 10 with an inlet 101 and an outlet 102, a cover 20 placed in the inlet 101, a filter screen 30 embedded inside the floor drain housing 10, and a filter element 50 installed at the lower opening; the filter element 50 is screwed and locked inside the outlet 102 of the floor drain housing 10, and the top periphery of the filter element 50 has a stop portion 52 that extends into the floor drain housing 10; when the cover 20 and the filter screen 30 are removed from the floor drain housing 10, an operating cavity 103 is formed inside the floor drain housing 10 for a human hand to reach in and rotate to unlock the filter element 50.

[0023] The structure of each component of this utility model will be described below.

[0024] like Figures 3-5As shown, the bottom circumferential surface of the drain housing 10 has an annular stepped groove 11 for mounting the support part 52. The outlet 102 is coaxially positioned in the middle of the annular stepped groove 11. The outer diameter of the filter element 50 is smaller than the outer diameter of the outlet 102, and the outer diameter of the support part 52 is larger than the outer diameter of the outlet 102. Two L-shaped locking members 51 are symmetrically fixed on the outer wall of the filter element 50 near the support part 52. The inner wall of the outlet 102 protrudes inward to form two spaced arc-shaped segments 12. The two arc-shaped segments 12 are positioned between their opposite ends. An avoidance hole 120 is formed to allow space for the arc-shaped segment 12; the locking member 51 includes a horizontal part 511 extending axially along the filter element 50 and a hook anchor part 512 vertically fixed at the end of the horizontal part 511. A locking groove 510 is formed between the horizontal part 511 and the hook anchor part 512. When the arc-shaped segment 12 on the filter element 50 passes through the water outlet 102 and is located below the drain housing 10, the filter element 50 is rotated so that the end of the arc-shaped segment 12 is engaged in the locking groove 510 until it contacts the horizontal part 511, thus completing the quick locking installation of the filter element 50.

[0025] like Figure 5 As shown, two operating handles 521 are symmetrically fixed at the top of the support part 52 to facilitate rotating the support part 52. When removing the cover 20 and the filter screen 30 from the drain housing 10, you can directly put your hand into the operating cavity 103 and rotate the filter element 50 in the opposite direction by rotating the operating handle 521, so that the arc segment 12 is completely rotated out of the locking groove 510. At this time, the filter element 50 can be directly removed for replacement.

[0026] like Figure 3 As shown, a sealing ring 40 is embedded around the filter element 50. When the filter element 50 is screwed and locked inside the outlet 102 of the drain housing 10, one side of the sealing ring 40 is pressed and sealed with the support part 52, and the other side is pressed and sealed with the bottom of the annular stepped groove 11. This achieves a sealed installation between the filter element 50 and the drain housing 10, preventing water from seeping out through the gap between them and improving the sealing performance of the drain structure installation.

[0027] Combination Figures 1-5 The working principle of this utility model will be explained in detail below, as well as how to use this utility model to install and remove the filter element 50.

[0028] When installing filter element 50, first remove the cover 20 and filter screen 30, and align the hook anchor 512 on filter element 50 with the clearance hole 120, so that the hook anchor 512 passes through the outlet 102 and is located below the drain housing 10. At this time, hold the two operating handles 521 and rotate filter element 50 clockwise, so that the end of the arc-shaped section 12 is engaged in the locking groove 510 until it forms contact with the horizontal part 511. At this time, the sealing ring 40 is pressed between the rest part 52 and the annular stepped groove 11, thereby achieving quick and sealed installation of filter element 50 on drain housing 10. When replacing filter element 50, rotate filter element 50 counterclockwise, so that the arc-shaped section 12 is completely disengaged from the locking groove 510, and filter element 50 can be directly removed from drain housing 10.

[0029] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various modifications or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention, as defined by the claims.
