Technical Field
[0001] This utility model relates to a floor drain, specifically an odor-proof floor drain. Background Technology
[0002] Odor-proof floor drains are commonly used devices in the bathroom industry, mainly serving the function of drainage while also providing odor prevention. The structures of these products on the market vary widely, all focusing on drainage, odor prevention, and anti-clogging. There are floor drains that use magnetic force to close the drain channel, floor drains that use elastic force to close the drain channel, and others, etc. However, regardless of their functional effects, they all have one, two, or more problems in essence, namely: (1) the assembly and replacement of floor drains are relatively complicated, and many additional parts are required to increase functionality, which also increases costs accordingly; (2) the integrity of the function is achieved by occupying a larger volume, sacrificing volume to accommodate some functions.
[0003] To solve the above problems, it is necessary to develop an odor-proof floor drain that has high space utilization and is easy to assemble. Utility Model Content
[0004] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide an odor-proof floor drain.
[0005] The technical solution of this utility model is: an odor-proof floor drain, which includes a shell and a floor drain cover. The shell has a through hole that runs vertically through it. An odor-proof core is detachably installed in the through hole. The odor-proof core has a drain outlet that communicates with the through hole. A baffle for opening or closing the drain outlet is rotatably connected to the odor-proof core.
[0006] Furthermore, the odor-proof core includes a top plate and a boss protruding from the bottom of the top plate, with the drain outlet located on the outside of the boss, and the upper end of the baffle rotatably connected to the upper end of the boss.
[0007] Furthermore, the top plate has a through core hole that runs vertically through the top and bottom, and the core hole is connected to the through hole and the drain outlet.
[0008] Furthermore, a circular step is provided at the upper opening of the through hole, and the top plate of the odor-proof core is placed on the step.
[0009] Furthermore, a sealing ring is fitted between the outer wall of the top plate and the inner wall of the upper end of the through hole.
[0010] Furthermore, the outer wall of the top plate has an annular groove, into which the sealing ring is inserted.
[0011] Furthermore, the width of the boss gradually increases from top to bottom, and the baffle leans against the opening of the drain outlet at an angle.
[0012] Furthermore, the boss has a drain outlet on both the left and right sides, and the upper end of the boss has a bearing seat on both the left and right sides. The bearing seat has a shaft hole, and the upper end of the baffle has a rotating shaft. The rotating shaft is inserted into the shaft hole, so that the baffle is rotatably connected to the odor-proof core.
[0013] Furthermore, an auxiliary tube is connected to the lower end of the outer casing via a threaded connection.
[0014] Furthermore, the lower end of the outer shell is shaped like a frustum.
[0015] The beneficial effects of using the odor-proof floor drain provided by this utility model are as follows:
[0016] By detachably installing the odor-proof core inside the through hole of the outer shell and using the baffle to rotate to open or close the drain outlet, the odor-proof function is achieved. Compared with the complex structure and numerous parts of the floor drain on the market, the floor drain of this utility model has a simpler structure, is easier to assemble, and effectively reduces costs.
[0017] The odor-proof core is installed inside the through-hole of the outer casing, which effectively utilizes the internal space of the casing;
[0018] The baffle on the odor-proof core can close the drain outlet, effectively preventing foul odors from rising from the sewer.
[0019] Because the odor-proof core is removable, users can easily remove it for cleaning and maintenance, thereby extending the lifespan of the drain and maintaining its good performance. Attached Figure Description

Detailed Implementation
[0025] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:
[0026] like Figure 1 — Figure 4 As shown, an odor-proof floor drain includes a housing 1 and a drain cover 2. The housing 1 has a through hole 11 extending vertically, and an odor-proof core 3 is detachably installed inside the through hole 11. The odor-proof core 3 has a drain outlet 321 communicating with the through hole 11, and a baffle 4 for opening or closing the drain outlet 321 is rotatably connected to the odor-proof core 3. The drain cover 2 is placed on top of the odor-proof core 3.
[0027] like Figure 2 , Figure 4 As shown, the odor-proof core 3 includes a top plate 31 and a boss 32 protruding from the bottom of the top plate 31. The drain outlet 321 is located on the outside of the boss 32, and the upper end of the baffle 4 is rotatably connected to the upper end of the boss 32.
[0028] The top of the top plate 31 has a circular slot 313, into which the drain cover 2 is placed.
[0029] like Figure 3 As shown, the top plate 31 has a through hole 311 extending vertically. The through hole 311 is connected to the through hole 11 and the drain outlet 321.
[0030] like Figure 2 , Figure 3 As shown, in order to facilitate the installation of the odor-proof core 3, a circular step 111 is provided at the upper opening of the through hole 11, and the top plate 31 of the odor-proof core 3 is placed on the step 111.
[0031] like Figure 2 — Figure 4 As shown, in order to improve the side sealing effect between the odor-proof core 3 and the outer shell 1, a sealing ring 5 is fitted between the outer wall of the top plate 31 and the upper inner wall of the through hole 11. The outer wall of the top plate 31 has an annular groove 312, and the sealing ring 5 is fitted into the annular groove 312.
[0032] like Figure 2 As shown, the width of the boss 32 gradually increases from top to bottom, and the baffle 4 leans against the opening of the drain outlet 321 at an angle. The purpose of this design is to allow the baffle 4 to effectively lean against the opening of the drain outlet 321, thereby blocking the drain outlet 321.
[0033] like Figure 2 , Figure 4 As shown, the boss 32 has a drain outlet 321 on both the left and right sides. To facilitate the installation of the baffle 4, the upper left and right sides of the boss 32 have bearing seats 322, each with a shaft hole 3221. The upper end of the baffle 4 has a rotating shaft 41, which is inserted into the shaft hole 3221, allowing the baffle 4 to be rotatably connected to the odor-proof core 3. When water enters the outer casing 1, it flows into the odor-proof core 3, causing the baffle 4 to open. When there is no water, the baffle 4 rests against the opening of the drain outlet 321 by its own weight.
[0034] like Figure 2 As shown, an auxiliary pipe 6 is connected to the lower end of the outer casing 1 via a threaded connection. Considering the issues of the drain pipe's height above the ground or its misaligned installation in actual installation environments, such as when the drain pipe is very far from the ground and the outer casing 1 cannot reach it, the auxiliary pipe 6 can be installed to overcome this distance.
[0035] like Figure 2 As shown, the lower end of the outer casing 1 is shaped like a frustum, meaning that the width of the lower end of the outer casing 1 is "wider at the top and narrower at the bottom", which makes it easy to adapt to drain pipes of different diameters.
[0036] This utility model achieves odor prevention by detachably installing the odor-proof core 3 in the through hole 11 of the outer shell 1 and opening or closing the drain outlet 321 by rotating the baffle 4. Compared with the complex structure and numerous parts of the floor drain on the market, the floor drain structure of this utility model is simpler, easier to assemble, and effectively reduces costs.
[0037] The odor-proof core 3 of this utility model is installed in the through hole 11 of the outer shell 1, which effectively utilizes the internal space of the outer shell 1 and the odor-proof core 3 does not take up too much space.
[0038] The baffle 4 on the odor-proof core 3 of this utility model can close the drain outlet 321, effectively preventing the odor from rising from the sewer.
[0039] Because the odor-proof core 3 is detachable, users can easily remove it for cleaning and maintenance, thereby extending the service life of the floor drain and maintaining its good performance.
[0040] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
