The traditional water seal type floor drain mainly comprises a floor drain main body and a water filtering cover, wherein a water drain port and a water trap are arranged on the floor drain main body, and sealing is realized by utilizing water flow in the water trap so as to prevent odor of a sewer from rising; however, the water sealing area of the water sealing floor drain is shallow and has little water storage capacity, and the water sealing effect is lost due to the dry water of the water storage trap caused by the factors of time, weather dryness and the like, so that the odor is returned.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the buoyancy opening and closing water seal deodorization floor drain, which realizes the functions of water drainage and water seal by utilizing buoyancy, and simultaneously ensures that the water seal has long effective time and better deodorization effect.
In order to achieve the above purpose, the buoyancy opening-closing water seal deodorization floor drain provided by the invention comprises a base and a water filtering cover arranged at the upper end of the base, wherein the base is a hollow cylinder with an opening at the upper end and a closed lower end, a circle of hooking grooves are formed in the base and positioned in the middle of the base, a floating body is arranged in the base, the floating body comprises a guide pipe with a central hole and a convex ring arranged at the periphery of the middle of the guide pipe, a first water outlet is formed in the side surface of the lower part of the base, and the position of the first water outlet is higher than the bottom of the base; the convex ring can be buckled in the hooking groove along with the downward movement of the floating body, so that a first water storage space is formed at the upper part of the base, and a second water storage space is formed at the bottom of the base. After water flow enters the first water storage space, the floating body is tightly buckled with the hooking groove under the action of self gravity and water flow gravity, the water flow forms a first water seal in the first water storage space, the sealing effect is ensured, water leakage is avoided, and odor of a sewer cannot enter a room; when the water flow is continuously increased, the water flow enters the second water storage space through the central hole of the guide pipe to form a second water seal, and the second water seal can ensure that the odor of the sewer cannot enter the room from the opening at the lower end of the guide pipe.
Further, the upper end opening of the conduit is lower than the upper end opening of the base, and the lower end opening of the conduit is lower than the lowest position of the first water outlet. The upper end opening of the guide pipe is lower than the upper end opening of the base so as to ensure that the floating body has a rising space under the action of buoyancy; the lower end opening of the guide pipe is lower than the lowest position of the first water outlet so as to ensure that a second water seal can be formed, and odor of a sewer cannot enter the room from the lower end opening of the guide pipe.
Further, the volume from the bottom of the first water storage space to the space flush with the upper end of the conduit is not smaller than the volume of the second water storage space; the design can ensure that when a large amount of water does not enter the water seal device, the floating body cannot float upwards due to too much water at the second water seal, so that the first water seal fails.
Further, the base includes base upper segment, base middle section and base hypomere, and base upper segment and base hypomere are cylindrical structure, and the base middle section is frustum shape structure, and the internal diameter of the cylindrical structure of base upper segment is the same with the internal diameter of frustum shape structure upper end, and the internal diameter of the cylindrical structure of base hypomere is less than the internal diameter of frustum shape structure hypomere, the base middle section links to each other through a support frame with the base hypomere, is equipped with the second delivery port that link up on this support frame. The shape of each section of the base is designed according to the design, so that the water flow volume of the first water seal and the second water seal can be guaranteed to meet the requirement, and meanwhile, the inclined surface of the conical table has a guiding function and is convenient to install on a sewer pipe.
Further, the hooking groove is arranged at the lower end of the frustum-shaped structure, a circle of groove is arranged at the middle position of the bottom of the hooking groove, and the convex ring is buckled in the groove. The groove can play a role in positioning the convex ring so as to ensure the sealing effect of the first water seal.
Further, the density of the material of which the floating body is made is smaller than that of water, so that when a large amount of water enters the floating body, the floating body can float upwards smoothly, and the drainage function is guaranteed.
Further, the periphery of the opening at the upper end of the base is provided with a step, so that the invention can be clamped on a sewer pipe without slipping.
Further, a plurality of water filtering holes are formed in the water filtering cover so as to ensure that water on the indoor ground can enter the water filtering cover.
The application principle and the acting process of the invention are as follows:
the invention is arranged on a sewer pipe through a step on the base, and after water flow enters the invention from the water filtering hole of the water filtering cover, the water flow is gathered in the first water storage space at first; when the water quantity entering the water storage device is more and more, water flow can enter the guide pipe from the upper end opening of the guide pipe so as to enter the second water storage space at the bottom of the base, and then is discharged from the first water outlet; however, when a large amount of rapid water flow enters the second water storage space, the water flow is not discharged quickly, the water quantity at the bottom of the base is enough to enable the floating body to float upwards, the convex ring of the floating body is separated from the hooking groove of the base, and most of the water flow entering the water storage device flows out from the separation position of the convex ring and the hooking groove and is discharged into the sewer pipeline through the second water outlet. In the process of reducing the water flow entering the water storage device to stop, the floating body sinks under the action of the gravity of the floating body and the gravity of the water flow in the first water storage space, the convex ring is matched with the hooking groove to form a first water seal, the bottom of the first water storage space is sealed, and odor entering a room is blocked; the second water storage space at the bottom of the base is also filled with water flow to form a second water seal, so that odor is prevented from entering the room through the opening at the lower end of the guide pipe.
In the evaporation and drying process of the water flow in the second water storage space, the water flow at the upper part of the first water storage space gradually supplements water quantity for the second water storage space, so that the effective time of the second water seal is prolonged; in addition, the volume from the bottom of the first water storage space to the space flush with the upper end of the conduit is not smaller than the volume of the second water storage space, and after the second water seal is completely dried, the first water seal is not dried yet, so that the water seal function is continuously exerted, and the effective time of the water seal is further prolonged.
By adopting the technical scheme, the buoyancy opening and closing water seal deodorization floor drain provided by the invention skillfully utilizes the cooperation of the convex ring of the floating body and the hooking groove of the base to realize the drainage of large water volume and the first water seal, has strong water flow passing capability and is not easy to block; meanwhile, the second water seal is realized by utilizing the guide pipe of the floating body and the inner wall of the base, and the first water seal is matched, so that the invention has strong evaporation resistance, long effective time of the water seal and good deodorization effect.
