Description
Technical Field
[0001] The utility model belongs to the technical field of floor drains, and particularly relates to an anti-odor floor drain core. Background Art
[0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor, and is an important component of the drainage system. The floor drain core is the core component of the floor drain, which is used to ensure that the floor drain has functions such as drainage, odor prevention, anti-clogging and easy cleaning.
[0003] A Chinese patent with announcement number CN205314228U discloses a straight-through odor-proof floor drain, including a floor drain shell, a sealing cover and a reset device. The floor drain shell is through-through from top to bottom, and a guide plate is formed on one side of the interior of the floor drain shell. The lower edge of the guide plate is connected to the lower edge of the floor drain shell to form a water outlet. The sealing cover is hinged under the guide plate, and the shape of the sealing cover is adapted to the shape of the water outlet. The reset device is a torsion spring arranged at the hinge, and the torsion spring applies a torque to the sealing cover so that the sealing cover seals the water outlet.
[0004] The above technical solution has the following defects: the above floor drain drives the sealing cover to seal the water outlet through the reset device, and the water outlet can be automatically sealed in the absence of water to prevent odor from overflowing from the sewer into the room; when the gravity of the sewage in the water outlet is greater than the force of the reset device, the sealing cover is opened to achieve drainage. However, the guide plate occupies half of the space in the floor drain shell, resulting in a small drainage area of the water outlet, and the drainage speed of the above floor drain is slow. In addition, the above floor drain uses a torsion spring as a reset part, and the torsion spring is directly exposed under the sealing cover. The water vapor in the sewer pipe will adhere to the torsion spring. As the use time increases, the torsion spring is prone to rust and the torque is reduced, which eventually leads to a decrease in the sealing performance of the sealing cover. In actual applications, the performance of this type of floor drain is not ideal. Utility Model Content
[0005] The purpose of the utility model is to propose an anti-odor floor drain core in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is: how to improve the performance of the floor drain core.
[0006] The above technical objectives of the utility model can be achieved through the following technical solutions:
[0007] A deodorizing floor drain core comprises an outer shell, a sealing assembly, a sealing cover and a reset mechanism, wherein the outer shell has a water inlet, the sealing assembly is arranged in the outer shell, and the sealing assembly has a water outlet connected to the water inlet; the lower end of the outer shell has a support arm, the support arm is provided with a support, the sealing cover is located between the water outlet and the support, and the sealing cover is slidably connected to the support; the reset mechanism is arranged in the sealing cover and / or the support, and the reset mechanism can apply a pre-tightening force to the sealing cover, so that the sealing cover and the sealing assembly cooperate to seal the water outlet.
[0008] When the ground sewage flows from the water inlet into the water outlet and the weight of the sewage is greater than the preload of the reset mechanism, the sealing cover moves downward and opens the water outlet to achieve drainage of the local leakage core; after drainage, the reset mechanism pushes the sealing cover toward the sealing component again to close the water outlet, thereby ensuring the deodorization effect. The drainage area of the water outlet is larger, the drainage efficiency is high, and the reset mechanism is built-in, which can effectively ensure the service life of the reset mechanism, and the local leakage core has better performance in actual use.
[0009] In the above-mentioned odor-proof floor drain core, the support arm includes a connecting portion and a supporting portion connected to each other, the connecting portion is connected to the outer shell, and the supporting portion extends toward the center of the outer shell and is located below the sealing cover. The supporting portion is connected to the outer shell through the connecting portion, and after the support is connected to the supporting portion, the support can provide a stable supporting force for the reset mechanism.
[0010] In the above-mentioned odor-proof floor drain core, the side wall of the connecting part has a clearance groove for the sealing cover to slide, and the connecting part will not interfere with the normal sliding of the sealing cover.
[0011] In the above-mentioned odor-proof floor drain core, a plurality of reinforcing ribs are arranged at the connection between the connection part and the support part. The reinforcing ribs increase the structural strength of the connection between the connection part and the support part, making the support part more stable.
[0012] In the above-mentioned odor-proof floor drain core, the reinforcing ribs have guide surfaces, and at least one reinforcing rib extends toward the outer wall of the supporting portion. The guide surfaces can assist the local drain core to be inserted into the floor drain.
[0013] In the above-mentioned odor-proof floor drain core, the sealing assembly includes a pressure cap and a sealing member. The pressure cap is detachably connected to the housing. The water outlet is provided in the pressure cap. An installation groove for installing the sealing member is provided outside the pressure cap. The lower end of the sealing member has an elastically deformable sealing flap, which can abut against the upper end surface of the sealing cover. The pressure cap limits the seal, and after the sealing cover abuts against the sealing flap, the water outlet can be isolated from the sewer, thereby ensuring the odor-proof effect of the local drain core.
[0014] In the above-mentioned odor-proof floor drain core, the center of the sealing cover has an upwardly protruding dome, and the dome can extend into the water outlet. The dome guides the sewage in the water outlet, further accelerating the discharge speed of the sewage in the water outlet; moreover, the sealing cover with the dome is not easy to have solid impurities remaining on the upper end surface.
[0015] In the above-mentioned odor-proof floor drain core, the support is connected to the support part, the support has a central hole, and the lower end of the sealing cover has a guide tube that slides with the central hole. The sealing cover is slidably connected with the central hole through the guide tube, thereby ensuring the sliding direction of the sealing cover.
[0016] In the above-mentioned odor-proof floor drain core, the reset mechanism includes an annular magnet arranged in the support, a magnetic column arranged in the guide tube, and the magnetic column is located above the annular magnet, and the magnetic force between the magnetic column and the annular magnet is a repulsive force. The annular magnet and the magnetic column are in a built-in state, and the magnetism of the two is more durable; in a limited space, the volume and magnetic force of the annular magnet are larger, which effectively ensures the preload force provided by the reset mechanism.
[0017] In the above-mentioned odor-proof floor drain core, a plurality of convex ribs are arranged at intervals on the hole wall of the central hole, the convex ribs guide the guide tube, air grooves are formed between adjacent convex ribs, the support is provided with notches connecting the air grooves; the lower end of the support is provided with an air vent connecting the central hole. The convex ribs guide the guide tube, and the notches and air grooves are provided, so that even if the lower end of the sealing cover abuts against the upper end of the support, the sealing cover and the support will not adhere to each other, ensuring that the sealing cover can be reset normally.
[0018] In summary, the beneficial effects of the present invention compared with the prior art are as follows:
[0019] When drainage is needed, sewage can press the sealing cover down to open the water outlet. The area of the water outlet for sewage discharge is larger, which can effectively improve the drainage efficiency, and the support arm can limit the sliding stroke of the sealing cover; when drainage is not required, the pre-tightening force always applied to the sealing cover by the reset mechanism will press the sealing cover against the sealing petal, thereby sealing the water outlet, thereby ensuring the anti-odor performance of the local leakage core. The setting of the magnetic column and the annular magnet ensures the stability and durability of the pre-tightening force; the structure of the local leakage core is more reasonable. On the premise of ensuring drainage efficiency, the sealing performance is more stable, the service life is longer, and the performance in actual use is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0032] A deodorizing floor drain core, such as Figures 1 to 6 As shown, it includes a shell 100, a sealing assembly 200, a sealing cover 300 and a reset mechanism 400. The shell 100 has a water inlet 110, the sealing assembly 200 is arranged in the shell 100, and the sealing assembly 200 has a water outlet 211 connected to the water inlet 110; the upper end of the shell 100 is connected to a handle 120, the lower end of the shell 100 has a support arm 130, and the support arm 130 is provided with a support 500, the sealing cover 300 is located between the water outlet 211 and the support 500, and the sealing cover 300 is slidably connected to the support 500; the reset mechanism 400 is arranged in the sealing cover 300 and / or the support 500, and the reset mechanism 400 can apply a pre-tightening force to the sealing cover 300, so that the sealing cover 300 and the sealing assembly 200 cooperate to seal the water outlet 211.
[0033] The support arm 130 includes a connecting portion 131 and a supporting portion 132 connected to each other. The connecting portion 131 is integrally formed or clamped with the housing 100 . The supporting portion 132 is located at the lower end of the connecting portion 131 . The supporting portion 132 extends toward the center of the housing 100 and is located below the sealing cover 300 .
[0034] The side wall of the connecting portion 131 has a relief groove 1311 to prevent the connecting portion 131 from interfering with the sliding of the sealing cover 300. In some embodiments, the relief groove 1311 is flush with the inner wall of the housing 100.
[0035] A plurality of reinforcing ribs 133 are provided at intervals at the connection between the connecting portion 131 and the supporting portion 132. The reinforcing ribs 133 have guide surfaces 1331. Figure 1 As shown, at least one reinforcing rib 133 extends toward the outer wall of the supporting portion 132 to increase the structural strength of the supporting portion 132 itself.
[0036] like Figure 3 , Figure 5 As shown, the sealing assembly 200 includes a pressing cap 210 and a sealing member 220. The pressing cap 210 is snap-fitted or threadedly connected to the outer shell 100. The water outlet 211 is opened in the pressing cap 210. The outer wall of the pressing cap 210 is provided with an installation groove 212 for installing the sealing member 220. The lower end of the sealing member 220 has an elastically deformable sealing flap 221. The sealing flap 221 is used to fit tightly against the upper end surface of the sealing cover 300, thereby sealing the lower end of the water outlet 211.
[0037] The sealing cover 300 has an upwardly protruding dome 310 at its center, and the dome 310 can extend into the water outlet 211 .
[0038] like Figure 3 , Figure 4 As shown, the support 500 is coaxially arranged with the support part 132 and is threadedly connected. The support 500 has a central hole 510, and the lower end of the sealing cover 300 has a guide tube 320 that slides with the central hole 510. In order to further ensure the stable sliding of the sealing cover 300, a plurality of convex ribs 511 are arranged at intervals on the hole wall of the central hole 510, and the guide tube 320 is guided by each convex rib 511 to avoid the guide tube 320 from deflecting when sliding. An air groove 512 is formed between adjacent convex ribs 511, and a notch 520 connecting each air groove 512 is provided on the support 500. A vent hole 1321 connecting the central hole 510 is provided at the lower end of the support part 132, so that the air pressure below the central hole 510 and the sealing cover 300 tends to be balanced, and the sealing cover 300 and the support 500 are prevented from sticking due to the air pressure difference.
[0039] The reset mechanism 400 includes an annular magnet 410 disposed in the support 500 and a magnetic column 420 disposed in the guide tube 320, and the magnetic column 420 is always located above the annular magnet 410. The magnetic force between the magnetic column 420 and the annular magnet 410 is a repulsive force, which can always apply a pre-tightening force directed toward the water outlet 211 to the sealing cover 300, thereby ensuring that the water outlet 211 remains sealed by the sealing cover 300 when water is not discharged. As another solution, the reset mechanism 400 can also be a spring sleeved outside the guide tube 320.
[0040] Furthermore, the annular magnet 410 abuts against the support portion 132 via a gasket 411 , and a plug 321 is provided in the guide tube 320 to limit the magnetic column 420 ; the cross-sectional area of the annular magnet 410 is larger than the cross-sectional area of the magnetic column 420 .
[0041] The working principle of the utility model is as follows:
[0042] The local drain core is installed in the floor drain. When sewage flows from the water inlet 110 into the water outlet 211 and the weight of the sewage is greater than the magnetic repulsion between the annular magnet 410 and the magnetic column 420, the sealing cover 300 and the magnetic column 420 move downward synchronously. The sealing cover 300 moves away from the sealing flap 221 to open the water outlet 211, and the local drain core can drain water normally. The arch 310 accelerates the discharge of sewage from the edge of the sealing cover 300. At this time, the magnetic column 420 is still located above the annular magnet 410.
[0043] After drainage is completed, the magnetic repulsion between the annular magnet 410 and the magnetic column 420 will push the sealing cover 300 toward the sealing member 220. After the sealing cover 300 abuts against the sealing flap 221, the water outlet 211 is resealed. Since the annular magnet 410 and the magnetic column 420 are both built-in, they are prevented from contacting with water vapor, thereby ensuring the stability and durability of the magnetic repulsion between them. The annular magnet 410 and the magnetic column 420 will not be adsorbed by metal impurities mixed in the sewage, and the sealing performance of the sealing cover 300 and the sealing flap 221 is more stable.
