Description
Technical Field
[0001] The utility model relates to a floor drain, in particular to an anti-odor floor drain. Background Art
[0002] A floor drain is an important interface connecting a drainage pipe system and an indoor floor. As an important component of a drainage system in a residence, it can effectively achieve the drainage effect. The most common floor drain in life is the floor drain used in a bathroom. When a user takes a bath, water will fall on the ground and then be drained into the drainage pipe system through the floor drain. An anti-odor floor drain is a floor drain that can automatically close when not draining water, which can effectively prevent the odor in the drainage pipe from surging up to the ground.
[0003] During the actual use of an anti-odor floor drain, the water flowing on the ground will be mixed with impurities such as hair and dirt. In order to prevent hair and large-volume impurities from entering the drainage pipe system along with the water flow and causing pipe blockage, a filtering structure is provided at the drainage port of the floor drain. Since the floor drain itself is provided with an anti-odor structure, in order to avoid the situation that the internal structure of the floor drain is too large and the volume of the floor drain itself is too large, the anti-odor structure is a filter plate, and the filter plate is provided with a number of evenly distributed filter holes. Hair and large-volume impurities will be intercepted on the upper surface of the filter plate. Hair and large-volume impurities are extremely easy to accumulate on the upper surface of the filter plate, resulting in the blockage of the upper orifice of the filter hole. At this time, the water flow cannot normally pass through the floor drain and be drained into the drainage pipe system. At this time, only the hair and large-volume impurities accumulated on the upper surface of the filter plate can be cleaned. Since the upper surface of the traditional filter plate is flat, the interval time between each cleaning and blockage of the filter hole is extremely short, and the user needs to clean the floor drain frequently, which seriously increases the cleaning work of the user. Summary of the Invention

[0007] The anti-odor structure comprises a guiding rod arranged at the center of the upper surface of the anti-odor plate; the upper end of the guiding rod penetrates into the weight-reducing groove through the guiding hole; a screw hole is arranged at the center of the inner wall on the upper side of the weight-reducing groove; a screw joint screwed with the screw hole is arranged at the center of the upper end surface of the guiding rod; a spring sleeved outside the guiding rod is arranged between the inner wall on the upper side of the weight-reducing groove and the inner wall on the lower side of the opening and closing cover.
[0008] A ring-shaped screwing part extends downward from the edge of the lower end port of the shell, and the opening and closing cover is screwed outside the screwing part; the outer wall of the opening and closing cover is coplanar with the outer wall of the shell.

Therefore, the user can clean the floor drain once in a long time, effectively extending the interval between two cleaning operations and reducing the amount of cleaning work for the user.

[0020] The anti-odor structure includes a guiding rod 18 provided at the center of the upper surface of the anti-odor plate 6; the upper end of the guiding rod 18 penetrates into the weight-reducing groove 16 through the guiding hole 5; a threaded hole 19 is provided at the center of the inner wall on the upper side of the weight-reducing groove 16; a threaded joint 20 that is screwed to the threaded hole 19 is provided at the center of the upper end surface of the guiding rod 18; a spring 21 that sleeved outside the guiding rod 18 is provided between the inner wall on the upper side of the weight-reducing groove 16 and the inner wall on the lower side of the opening and closing cover.
[0021] A ring-shaped screwing portion 22 extends downward from the edge of the lower end port of the housing 1, and the opening and closing cover 3 is screwed outside the screwing portion 22; the outer wall of the opening and closing cover 3 is coplanar with the outer wall of the housing 1.
[0022] The guiding arc surface 15 is located inside the temporary storage groove 10; an outer guiding conical surface 23 with a narrow upper part and a wide lower part is provided on the outer wall of the upper end of the central tube 13.
[0023] An inner guiding conical surface 24 with a wide upper part and a narrow lower part is provided on the inner wall of the upper side orifice of the temporary storage groove 10.
[0024] Several auxiliary holes 25 that communicate with its internal space are provided on the outer wall of the central tube 13; several long circular holes 26 that communicate with its internal space are provided on the outer wall of the guiding head 14.
[0025] On the inner walls of the left and right sides of the temporary storage tank 10, there are symmetrically arranged force application grooves 27; on the upper inner wall of the force application groove 27, there are several uniformly distributed anti-slip grooves 28.
[0026] On the upper surface of the limiting block 9, there is a fixing hole 29; a pull rod 30 matching it is screwed in the fixing hole 29; the upper end of the pull rod 30 extends upward out of the fixing hole 29 and is provided with a rotating handle 31.
[0027] The usage method of the utility model is as follows:
[0028] When water needs to be discharged, the water flow will flow into the temporary storage tank 10 through the upper notch of the temporary storage tank 10. The water flow entering the temporary storage tank 10 is divided into two parts. One part directly impacts on the guiding arc surface 15, and the other part directly enters the bottom of the temporary storage tank 10. The water flow entering the bottom of the temporary storage tank 10 will flow into the lower space of the housing 1 through the lower filtering holes 11. The water flow impacting on the guiding arc surface 15 will flow into the weight reduction groove 16 through the upper filtering holes 17 and then immediately flow into the lower space of the housing 1. The water flow entering the lower space of the housing 1 will be discharged downward through the drain holes 4. At this time, under the action of water pressure, the odor prevention plate 6 is pushed downward, and the lower orifice of the drain hole 4 is no longer shielded and sealed. The water flow is discharged into the drainage pipe through the gap between the lower surface of the opening and closing cover 3 and the upper surface of the odor prevention plate 6 to achieve the drainage effect. When the odor prevention plate 6 moves downward, the guiding head 14 moves downward accordingly. At this time, the spring 21 is compressed and generates elasticity. When the water flow discharge ends, without the impact of water flow pressure, the odor prevention plate 6 will move upward and reset under the elastic action of the spring 21, and once again shield and seal the lower orifice of the drain hole 4, thus effectively avoiding the situation that the odor in the drainage pipe surges to the ground through the floor drain.
[0029] If the water flow is mixed with hair and large-volume impurities, since the guiding arc surface 15 is a smooth arc surface, under the scouring of the water flow, the impurities on the guiding arc surface 15 are extremely easy to enter the space formed by enclosing the inner wall of the temporary storage tank 10 and the outer wall of the central pipe 13 along the outer guiding conical surface 23. The space formed by enclosing the inner wall of the temporary storage tank 10 and the outer wall of the central pipe 13 can be used to accumulate hair and large-volume impurities. Even if the lower filtering holes 11 are blocked by hair and large-volume impurities, the water flow on the ground can still be discharged into the drainage pipe system through the upper filtering holes 17, so as to ensure normal drainage while prolonging the time for cleaning impurities. And when the odor prevention plate 6 is pressed downward by the discharged water flow, the guiding head 14 moves downward synchronously with the odor prevention plate 6. At this time, if there are impurities at the edge of the guiding arc surface 15, they will be scraped off by the upper end of the outer guiding conical surface 23 to realize the cleaning of impurities and avoid the situation that the impurities adhere to the edge of the guiding arc surface 15 to form resistance, resulting in the difficulty of scouring the impurities on the guiding arc surface 15 by the water flow.
[0030] A ring-shaped screwing part 22 extends downward from the edge of the lower end port of the housing 1. The opening and closing cover 3 is screwed outside the screwing part 22, and the outer wall of the opening and closing cover 3 is coplanar with the outer wall of the housing 1. This structural design can effectively avoid the situation that the outer wall of the opening and closing cover 3 protrudes too much and affects the installation of the floor drain.
[0031] An inner diversion conical surface 24 with a wider upper part and a narrower lower part is provided on the inner wall of the upper side notch of the temporary storage groove 10. The inner diversion conical surface 24 can guide the ground water flow to make it enter the temporary storage groove 10 faster.
[0032] A number of auxiliary holes 25 communicating with its internal space are provided on the outer wall of the central pipe 13, and a number of oblong holes 26 communicating with its internal space are provided on the outer wall of the diversion head 14. Since the length of the oblong holes 26 is relatively long, even if the diversion head 14 moves downward along the track of the central pipe 13, some of the auxiliary holes 25 can still be in a state of mutual communication with the oblong holes 26. Even if the upper orifice of the lower filtering hole 11 is blocked by impurities at this time, the water flow can flow into the weight reduction groove 16 through the auxiliary holes 25 and the oblong holes 26 in sequence, and finally be discharged through the drain hole 4, playing an auxiliary drainage effect.
[0033] Force application grooves 27 that are symmetrical to each other are provided on the inner walls on the left and right sides of the temporary storage groove 10. A number of uniformly distributed anti-slip grooves 28 are provided on the upper inner wall of the force application grooves 27. When the user needs to clean the impurities in the space formed by the enclosure of the inner wall of the temporary storage groove 10 and the outer wall of the central pipe 13, the user can hold the force application grooves 27 on the left and right sides and lift the temporary storage seat 7 upward to realize the separate disassembly of the temporary storage seat 7, which is convenient for the cleaning work. The existence of the anti-slip grooves 28 can effectively increase the friction when the hand is buckled in the force application grooves 27, which is convenient for applying force.
[0034] A fixing hole 29 is provided on the upper surface of the limit block 9. A pull rod 30 that matches it is screwed in the fixing hole 29. The upper end of the pull rod 30 passes upward out of the fixing hole 29 and is provided with a rotating handle 31. Considering the hygiene problem of the hand, the user can hold the rotating handle 31 and then pull the temporary storage seat 7 upward through the pull rod 30, which can also realize the disassembly of the temporary storage seat 7. In order to avoid the protruding pull rod 30 from causing injury to the user's feet, the pull rod 30 can be screwed out of the fixing hole 29 without disassembling the temporary storage seat 7.
