Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, specifically a bathroom floor drain that can clean hair. Background Technology

[0002] Floor drains are often perceived as dirty and rarely receive attention. After a period of use, they tend to become clogged with hair, affecting floor cleanliness and making them difficult to remove. Over time, the hair accumulated in the drain bend can obstruct drainage or even cause blockages. Floor drains are drainage devices that connect the floor to the drainage pipe system. Most existing floor drains are traditional floor drains installed on the floor, which also have many problems, such as poor self-cleaning ability, easy clogging, and difficulty in cleaning. The items that easily clog are mostly solids that are difficult to drain, such as hair and water stains.

[0003] As disclosed in the authorization announcement number CN112031128B, an odor-proof floor drain core that facilitates debris cleaning includes a floor drain core, a baffle, an air cylinder, a filter mechanism, and an exhaust / suction pipe. The floor drain core is a through-tube structure with a filter cover at the top and an inwardly inclined edge in the middle. The baffle is movably connected to the lower end of the floor drain core, and the filter mechanism is detachably connected to the edge. The air cylinder is made of a compressible elastic material, with a connecting cap fixedly connected to the upper end and the connecting cap fixedly connected to the floor drain core. The lower end of the air cylinder is connected to the top of the baffle. The exhaust / suction pipe is fixedly connected to the right side inside the connecting cap and has an exhaust / suction channel. The exhaust / suction channel accelerates airflow in the forward direction and decelerates airflow in the reverse direction. This design solves the problem in the prior art where the surface of the floor drain is clogged with hair, water stains, and other solids that are difficult to drain and clean, thus affecting floor cleanliness. At the same time, odors or insects can enter the room through the floor drain, affecting people's lives.

[0004] However, the structure of an odor-proof floor drain core that is easy to clean is relatively complex in the existing technology CN112031128B, and it lacks a filter screen length adjustment mechanism. It is difficult to flexibly adapt to different lengths of connecting water pipes or usage environments, and it is not convenient to use. Therefore, we propose a bathroom floor drain that can clean hair, which solves the filter screen length adjustment problem of the utility model, improves the flexibility of use of the utility model, and expands its application scope. Utility Model Content

[0005] The purpose of this invention is to provide a bathroom floor drain that can clean hair, in order to solve the problem mentioned in the background art that the length of the filter screen cannot be adjusted in the existing odor-proof floor drain core that is easy to clean debris.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bathroom drain that can clean hair includes a pre-embedded ring, a first filter mechanism inserted inside the pre-embedded ring, and a second filter mechanism slidably sleeved inside the first filter mechanism. The first filter mechanism includes a first filter screen, a lifting ring at the top of the first filter screen, and a threaded rod fixedly connected to the bottom of the lifting ring. The lifting ring is rotatably connected to the first filter mechanism. A limiting slide is provided on the inner wall of the first filter screen. The second filter mechanism includes a second filter screen, a limiting slide groove corresponding to the limiting slide is opened on the outer side of the top of the second filter screen, and a fixing rod is fixedly provided at the top of the second filter screen. The threaded rod is threadedly connected to the fixing rod.

[0008] Preferably, the fixing rod has a threaded hole in the middle, the threaded rod is screwed into the threaded hole, and a limit piece is provided at the bottom end of the threaded rod.

[0009] Preferably, the second filtration mechanism further includes a cover, the inner wall of which is provided with internal threads, and the outer wall of the bottom end of the second filter screen is provided with external threads.

[0010] Preferably, the cover is screwed to the bottom end of the second filter screen, and the cover is provided with filter holes with the same density and diameter as the second filter screen.

[0011] Preferably, the pre-embedded ring is provided with a groove, and the top of the first filter screen is provided with a retaining ring that fits into the groove.

[0012] Preferably, the embedded ring, the first filter screen, the second filter screen and the cover are all made of 304 stainless steel, and the inner diameter of the filter hole of the first filter screen is 1.5 times the inner diameter of the filter hole of the second filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This bathroom floor drain, designed to clean hair, rotates a lifting ring clockwise, causing a threaded rod to rotate synchronously. This moves a fixed rod downwards, further causing the second filter screen to move downwards along a limiting slide bar. This extends the length of the filter screen, increasing its internal volume or filtration area and preventing it from accumulating too quickly and becoming clogged. It is suitable for environments with a lot of hair or debris. Furthermore, its length can be adjusted to accommodate different lengths of drain pipes connected to the floor drain, making it more flexible and convenient to use.

[0015] 2. This bathroom floor drain, designed to clean hair, facilitates quick cleaning through a cap screwed to the bottom of the second filter. The inner diameter of the filter holes in the first filter is 1.5 times that of the second filter; the finer second filter helps to intercept smaller particles of hair or debris, preventing them from flowing into the pipe and causing blockages, thus improving the drain's practicality.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A bathroom drain that can clean hair includes a pre-embedded ring 100, a first filter mechanism inserted inside the pre-embedded ring 100, and a second filter mechanism slidably sleeved inside the first filter mechanism. The first filter mechanism includes a first filter screen 200, a lifting ring 201 at the top of the first filter screen 200, and a threaded rod 202 fixedly connected to the bottom of the lifting ring 201. The lifting ring 201 is rotatably connected to the first filter mechanism. A limiting slide strip 203 is provided on the inner wall of the first filter screen 200. The second filter mechanism includes a second filter screen 300, a limiting slide groove 301 corresponding to the limiting slide strip 203 is opened on the outer side of the top of the second filter screen 300, and a fixing rod 302 is fixedly provided at the top of the second filter screen 300. The threaded rod 202 is threadedly connected to the fixing rod 302.

[0024] In this embodiment, preferably, the fixing rod 302 has a threaded hole 303 in the middle, the threaded rod 202 is screwed to the threaded hole 303, and a limiting piece 304 is provided at the bottom end of the threaded rod 202.

[0025] In this embodiment, preferably, the second filtration mechanism further includes a cover 305, the inner wall of which is provided with an internal thread 306, and the outer wall of the bottom end of the second filter screen 300 is provided with an external thread 307.

[0026] In this embodiment, preferably, the cover 305 is screwed to the bottom end of the second filter screen 300, and the cover 305 is provided with filter holes 308 with the same density and diameter as the second filter screen 300.

[0027] In this embodiment, preferably, the pre-embedded ring 100 is provided with a groove 101, and the top of the first filter screen 200 is provided with a retaining ring 204 that fits into the groove 101.

[0028] In this embodiment, preferably, the embedded ring 100, the first filter screen 200, the second filter screen 300 and the cover 305 are all made of 304 stainless steel, and the inner diameter of the filter hole of the first filter screen 200 is 1.5 times the inner diameter of the filter hole of the second filter screen 300.

[0029] In this embodiment, a bathroom floor drain capable of cleaning hair is first installed by embedding a pre-embedded ring 100 below the floor level of the usage area. Then, a first filter screen 200 is inserted into the pre-embedded ring 100, so that the retaining ring 204 at the top of the first filter screen 200 engages with the groove 101 inside the pre-embedded ring 100. At this time, the operator can choose whether to adjust the length of the filter screen according to the actual usage environment. If the user has severe hair loss or the connecting pipe is long, the lifting ring 201 can be rotated clockwise, which drives the threaded rod 202 to rotate synchronously, thereby driving the fixed rod 302 to move downward, and further driving the second filter screen 300 to move downward along the limiting slide 203, thus achieving the effect of lengthening the filter screen, so as to increase the internal volume of the filter screen or the filtration working area, and avoid the accumulation of hair or debris too quickly, which would cause blockage. When the user has mild hair loss or the connecting pipe is short, the operation is reversed, so that the length of the filter screen is shortened. After the drain has been used for a period of time, the filter screen can be pulled out of the pre-embedded ring 100 by lifting the ring 201, then the cover 305 can be rotated to pour out the impurities inside, and then the cover 305 can be tightened and reinserted into the pre-embedded ring 100 for continued use. This cover 305 structure is more convenient for cleaning the impurities inside the filter screen than conventional fixed drains, which is beneficial for long-term use.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
