[0002] There are various styles of existing odor-proof floor drains, such as water-sealed floor drains, magnetic levitation floor drains, spring-suspended floor drains, flap-type floor drains, etc. Among them, the water-sealed floor drain will lose its odor-proof effect after the water used for the water seal evaporates when it is not used for a long time, and it is easy to cause impurities to precipitate and reduce the water flow; the magnetic levitation floor drain will also lose its odor-proof and anti-overflow functions after hair is entangled; the spring-suspended pull-type drain will also fail due to hair entanglement, and the sealing is not good; the flap-type floor drain will affect the odor-proof and lose its sealing under impurities such as dirt and hair.
[0003] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which resulted in the present case. Utility Model Content
[0004] The utility model aims to provide an anti-odor floor drain with good sealing performance and strong anti-odor, anti-insect and anti-overflow effects.
[0005] The utility model discloses an odor-proof floor drain core, comprising a core body, on which an odor-proof structure is arranged, the core body having a hollow tube body with upper and lower ends opened; the odor-proof structure having an outer sleeve and a sealing cover, the outer sleeve being a hollow tube body with an open upper end face and a closed lower end face, the lower end of the core body being suspended and extending into the outer sleeve, and being detachably connected with the core body, and a water outlet channel being formed between the outer side wall of the outer sleeve and the inner side wall of the core body, a water outlet hole connected with the water outlet channel being arranged on the outer side wall of the core body, the sealing cover being mounted on the outside of the core body in a manner capable of moving up and down and covering the upper end portion of the outer sleeve to seal the water outlet channel, and the sealing cover being in sealing cooperation with the core body.
[0006] The core body comprises an upper diameter-expanding section and a lower diameter-reducing section. The lower portion of the lower diameter-reducing section extends into the outer sleeve and is detachably connected to the outer sleeve. The sealing cover is sleeved outside the lower diameter-reducing section.
[0007] The outer sleeve has an upper pipe section and a lower pipe section, the outer diameter of the upper pipe section is larger than the outer diameter of the lower pipe section, the lower end of the lower reduced diameter section extends into the lower pipe section and is threadedly connected to the lower pipe section, and the outer side wall of the lower reduced diameter section is provided with a plurality of water outlet holes distributed around the circumference at intervals, and the water outlet holes are located above the lower pipe section.
[0008] The sealing cover is a rubber block.
[0009] The sealing cover is in the shape of a trumpet that expands gradually from top to bottom, the bottom surface of the sealing cover is superimposed on the top surface of the upper pipe section, and the sealing cover and the lower reduced diameter section are sealed by an O-ring embedded in the sealing cover.

[0016] Figure 3 It is a three-dimensional diagram of another structure of the utility model. DETAILED DESCRIPTION
[0017] The utility model discloses an anti-odor floor drain core, such as Figure 1 , 2 As shown, it includes a core body 1, on which is provided an anti-odor structure, the core body 1 having a hollow tube body with upper and lower ends opened; the anti-odor structure has an outer sleeve 2 and a sealing cover 3, the outer sleeve 2 is a hollow tube body with an open upper end face and a closed lower end face, the lower end of the core body 1 is suspended and extends into the outer sleeve 2, and is detachably connected to the core body 1, and a water outlet channel (not shown in the figure) is formed between the outer wall of the outer sleeve 2 and the inner wall of the core body 1, a water outlet hole 100 connected to the water outlet channel is opened on the outer wall of the core body 1, the sealing cover 3 is mounted on the outside of the core body 1 in a manner that it can move up and down and is covered at the upper end of the outer sleeve 2 to seal the water outlet channel, and the sealing cover 3 is sealed with the core body 1.
[0018] The core body 1 comprises an upper enlarged diameter section 11 and a lower reduced diameter section 12, and the outer sleeve 2 comprises an upper tube section 21 and a lower tube section 22. The outer diameter of the upper tube section 21 is greater than the outer diameter of the lower tube section 22, and the inner diameter of the upper tube section 21 is also greater than the inner diameter of the lower tube section 22. The lower end of the lower reduced diameter section 12 extends into the lower tube section 22 and is screwed together with the lower tube section 22 by means of internal and external threads. The depth of the lower tube section 22 is about 5-10 cm, and the outer diameter of the lower reduced diameter section 12 is smaller than the inner diameter of the upper enlarged diameter section 11. The lower part of the lower reduced diameter section 12 is suspended in the upper part of the upper tube body 21, and there is a first distance between the lower outer wall of the lower reduced diameter section 12 and the upper inner wall of the upper tube body 21, and this first distance is the water outlet channel; the lower outer wall of the lower reduced diameter section 12 is located in the upper tube body and is provided with a plurality of through holes distributed around the circumferential direction, and two through holes are preferably arranged, and this through hole is the water outlet hole 100, and the water outlet hole 100 is located above the lower tube body 21.
[0019] The sealing cover 3 is sleeved on the outside of the lower reduced diameter section 12. The sealing cover 3 is preferably an elastic block, preferably a rubber block, or a mixed material of rubber and plastic. It can also be made of other materials. The sealing cover 3 is in the shape of a trumpet that gradually expands from top to bottom. The surface slope is used to prevent dust and insects from climbing up and affecting the normal upper and lower sealing and opening actions of the sealing cover; the lower bottom surface of the sealing cover 3 is superimposed on the top surface of the upper pipe section 21, and the sealing cover 3 and the lower reduced diameter section are sealed by an O-ring (not shown in the figure) embedded in the sealing cover 3.
[0020] The utility model provides an odor-proof floor drain core. When no water is discharged, the sealing cover 3 can always be covered on the top surface of the upper pipe section 21 by its own gravity, and the cover is arranged on the upper pipe body 21 to seal the water outlet channel. At this time, the floor drain core realizes a single seal. In addition, water flows down into the core body and then flows into the water outlet channel through the water outlet hole 100. At this time, the water stays in the water outlet channel to achieve a water seal effect. At this time, the floor drain core realizes a double seal. The entire floor drain core is doubly sealed, and the sealing effect is good. When the floor drain is not used for a long time, after the water in the water outlet channel (that is, the water in the water seal) evaporates and dries, the sealing cover 3 can still play a sealing effect under its own gravity, and the odor-proof, insect-proof and overflow-proof capabilities are excellent, and the sewer is completely isolated from the living space. At the same time, this structure can make the length of the outer shell not too long, reduce the water seal depth, make the water flow have a good scouring effect on the bottom surface of the outer shell, and avoid the generation of water seal sediment debris; when water is discharged, the water flows into the core and flows into the water outlet channel through the water outlet hole 100. At this time, when there is too much water in the water outlet channel, the water pressure will push the sealing cover upward, so that the water flows out from the outer sleeve 2 to achieve the water outlet function. When the core no longer discharges water, the water flow will not push the sealing cover 3 upward. The sealing cover 3 uses its own gravity to fall again to seal the outer sleeve 2 to achieve a single seal. A small amount of water is left in the water outlet channel to achieve the water seal function and double seal. The entire structure is simple, easy to disassemble and assemble, and easy to process and produce.
[0021] In the present invention, preferably, the lower bottom surface of the sealing cover 3 extends downward with a locking ring 31 which is locked in the water outlet channel. The locking ring 31 is used to make the sealing effect of the sealing cover 3 better, and the sealing cover 3 will not move up and down easily, and will not tilt to affect the normal upper and lower sealing and opening actions of the sealing cover.
[0022] In this new type, Figure 1 As shown, during installation, a sealing reducer rubber ring can be put on the outer side wall of the upper enlarged diameter section 11 and the floor drain body can be quickly plugged in and matched.
[0023] In this new type, Figure 3 As shown, an external screw thread 111 can be provided on the outer side wall of the upper diameter expansion section 11, and the external screw thread 111 can be used to realize the screw-in installation between the floor drain core and the floor drain body, which is convenient for installation. A closed annular convex ring 112 can also be provided on the upper end surface of the upper diameter expansion section 11 to protrude outward, and two oppositely arranged lugs 113 are protruded upward on the top surface of the closed annular convex ring 112, and a hanging hole is opened on the lug. A handle can be installed on the lug using the hanging hole on the lug, which facilitates the disassembly and assembly of the floor drain core on the floor drain.
[0024] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
