Technical Field

[0001] The utility model relates to the field of floor drains, in particular to a floor drain with a filter screen that can be conveniently disassembled. Background Art

[0002] A floor drain is an important interface connecting the drainage pipe system and the indoor ground. As an important component of the drainage system in a residence, its performance directly affects the indoor air quality and is very important for controlling the odor in the bathroom.

[0003] The current floor drain consists of a floor drain body, a bouncing core, and an external filter screen. The bouncing core controls the opening and closing of the floor drain, and the filter screen filters and blocks foreign objects. However, to prevent the existing filter screen from falling into the drainage pipe, the filter screen is usually directly fixed to the outside of the floor drain body. Although this increases the connection stability of the filter screen, it is also difficult to replace the filter screen separately, so replacing the filter screen requires replacing the floor drain synchronously.

[0004] At the same time, when installing the current floor drain, it usually needs to be installed at the floor drain panel. If the outer surface of the floor drain panel is not smooth enough, it is easy to cause leakage problems between the floor drain and the floor drain panel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a floor drain with a filter screen that can be conveniently disassembled, which can improve the disassembly convenience of the floor drain and the filter screen to ensure stable filtration and smooth water flow during daily use.

[0006] To solve the above technical problems, the utility model provides a floor drain with a filter screen that can be conveniently disassembled, including a floor drain body and a filter cylinder detachably connected to the bottom of the floor drain body. A plurality of limiting rods are arranged on the side of the floor drain body, and a plurality of limiting grooves are opened on the side of the filter cylinder. The limiting grooves are arranged in an L-shaped structure, and the limiting rods are matched with the limiting grooves so that when the limiting rods are buckled in the limiting grooves, the filter cylinder is connected to the floor drain body; one end of the floor drain body away from the filter cylinder is connected with a floor drain sticker, and the floor drain sticker is arranged circumferentially along the end of the floor drain body.

[0007] Further, convex points are arranged on the inner side of the corner position of the limiting groove so that when the limiting rods are buckled in the limiting grooves, the convex points limit the limiting rods.

[0008] Further, a guiding annular surface is arranged circumferentially at the bottom of the floor drain body, and the guiding annular surface is inclined.

[0009] Further, a clamping groove is arranged circumferentially on the floor drain body so that when the filter cylinder is installed at the floor drain body, the end of the filter cylinder is clamped in the clamping groove.

[0010] Further, one end of the floor drain body away from the filter cylinder has a limiting plate.

[0011] Further, a connection hole is formed at one end of the floor drain body close to the filter cylinder, and threads are provided inside the connection hole so that the bouncing core is connected to the floor drain body through the connection hole.

[0012] Further, a plurality of drainage grooves are formed in the circumferential direction at one end of the floor drain body close to the filter cylinder, and the drainage grooves are located inside the filter cylinder.

[0013] Further, reinforcing ribs are provided between two adjacent drainage grooves, and both ends of the reinforcing ribs are inclined.

[0014] The beneficial effects of the present utility model are as follows: The floor drain body is connected to the filter cylinder, so that the limiting rod is snapped into the limiting groove.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0024] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as limiting the quantity.

[0025] As Figures 1-5 described, the present invention provides a floor drain with a filter screen that can be conveniently disassembled, including a floor drain body 1 and a filter cylinder 2 detachably connected to the bottom of the floor drain body 1. A plurality of limiting rods 3 are arranged on the side of the floor drain body 1, and a plurality of limiting grooves 4 are opened on the side of the filter cylinder 2. The limiting grooves 4 are arranged in an L-shaped structure, and the limiting rods 3 are matched with the limiting grooves 4 so that when the limiting rods 3 are buckled in the limiting grooves 4, the filter cylinder 2 is connected to the floor drain body 1; one end of the floor drain body 1 away from the filter cylinder 2 is connected with a floor drain sticker 12, and the floor drain sticker 12 is arranged circumferentially along the end of the floor drain body 1.

[0026] Connect the floor drain body and the filter cylinder so that the limiting rod is snapped into the limiting groove. Then, rotate the filter cylinder relative to the floor drain body by a certain angle so that the limiting rod is buckled to the innermost side of the L-shaped limiting groove to ensure the matching of the limiting rod and the limiting groove, thereby ensuring the stable connection between the filter screen and the floor drain body. Then, install the floor drain body at the position of the drainage pipe to facilitate filtering and draining the drainage pipe through the floor drain body and the filter cylinder. When it is necessary to replace the filter cylinder, only need to take out the floor drain body from the drainage pipe and rotate the filter cylinder in the reverse direction to disassemble the filter cylinder, thereby conveniently replacing the filter cylinder.

[0027] Meanwhile, through the setting of the floor drain sticker, the floor drain body is connected to the floor drain sticker. Subsequently, the floor drain sticker is adhered to the drainage pipe to be connected. Then, through the direct connection between the floor drain body and the floor drain sticker, the drainage stability of the floor drain is ensured, and the problem of leakage between the floor drain and the floor drain panel is avoided.

[0028] Among them, when connecting the floor drain sticker, it can be fixedly connected by means such as gluing or screw fixing.

[0029] Preferably, convex points 5 are arranged inside the corner positions of the limiting groove 4 so that when the limiting rod 3 is buckled in the limiting groove 4, the convex points 5 limit the limiting rod 3.

[0030] Specifically, after rotating the filter cartridge to buckle the limiting rod to the innermost end of the limiting groove, the limiting rod is limited by the convex points to prevent the filter cartridge from rotating by itself due to the impact of water flow, and further avoid the situation that the filter cartridge detaches from the floor drain body by itself.

[0031] Preferably, a guiding ring surface 6 is arranged along the circumference at the bottom of the floor drain body 1, and the guiding ring surface 6 is inclined.

[0032] Specifically, when installing the filter cartridge, due to the setting of the guiding ring surface, the guiding ring surface can conduct inclined guiding on the installation direction of the filter cartridge, improving the installation convenience and accuracy of the filter cartridge, and avoiding the situation of installation failure caused by the filter cartridge being stuck.

[0033] Preferably, a clamping groove 7 is formed along the circumference of the floor drain body 1 so that when the filter cartridge 2 is installed at the floor drain body 1, the end of the filter cartridge 2 is clamped in the clamping groove 7.

[0034] Specifically, when installing the filter cartridge, the axial installation of the filter cartridge can be limited through the clamping groove to ensure that the limiting rod will not be damaged due to excessive thrust. At the same time, through the clamping fit between the clamping groove and the end of the filter cartridge, the filtering effect of the filter cartridge can be improved, and the situation of water flow directly leaking out from the end of the filter cartridge can be avoided.

[0035] Preferably, one end of the floor drain body 1 away from the filter cartridge 2 has a limiting plate 8.

[0036] Specifically, when installing the floor drain body, the installation position of the floor drain body can be limited through the limiting plate to ensure that the relative position between the floor drain body and the floor drain sticker is accurate enough.

[0037] It is worth mentioning that a sealing ring is arranged at the connection between the limiting plate and the floor drain sticker to facilitate improving the drainage stability of the floor drain.

[0038] Preferably, a connection hole 9 is formed at one end of the floor drain body 1 close to the filter cartridge 2, and threads are arranged inside the connection hole 9 so that the bouncing core 13 is connected to the floor drain body 1 through the connection hole 9.

[0039] Specifically, through the setting of the connection holes, the bouncing core 13 can be stably connected to the floor drain body. And because the inside of the connection holes has threads, the bouncing core 13 can be threadedly connected to the connection holes, so that the bouncing core 13 can be conveniently disassembled and replaced from the connection holes.

[0040] Preferably, a plurality of drain grooves 10 are circumferentially formed at one end of the floor drain body 1 close to the filter cylinder 2, and the drain grooves 10 are located inside the filter cylinder 2.

[0041] Specifically, through the setting of the plurality of drain grooves, the water flow discharged from the floor drain can be respectively discharged to different positions of the filter cylinder through each drain groove, improving the filtering effect of the filter cylinder and preventing the water flow from being discharged to the same position of the filter cylinder, which may cause blockage at that position.

[0042] Among them, after installing the bouncing core to the connection holes, the opening and closing state of the floor drain is switched by pressing the bouncing core. When the bouncing core is in the open state, the water flow flows from the outside of the floor drain body through the bouncing core, then flows out through the drain grooves to the filter cylinder, and is discharged into the drainage pipe after being filtered by the filter cylinder.

[0043] Preferably, a reinforcing rib 11 is arranged between two adjacent drain grooves 10, and both ends of the reinforcing rib 11 are inclined.

[0044] Specifically, when installing the bouncing core, the installation of the bouncing core is guided by the inclined structures at both ends of the reinforcing rib, improving the installation accuracy of the bouncing core. When the floor drain body is in use, the structural strength of the drainage position can be increased through the reinforcing rib, thereby ensuring stable drainage.

[0045] The present utility model is not limited to the above best implementation manner. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as this application, they all fall within the protection scope of the present utility model.
