[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-Figure 4 As shown, the odor-proof drainage floor drain provided in the embodiment of the present application includes a floor drain housing 100, two cover plates 200 and a filter screen 300, wherein the floor drain housing 100 is the main structure of the floor drain, the floor drain housing 100 is installed on the indoor floor, a drain port 110 is provided on the floor drain housing 100, and the floor drain housing 100 is connected to a drain pipe through the drain port 110. Therefore, waste water flowing on the indoor floor can enter the drain pipe through the drain port 110 to realize waste water recycling.
[0028] Two cover plates 200 are hingedly connected to the side wall of the drain outlet 110 of the floor drain housing 100 through a hinged ear 210. The two cover plates 200 are symmetrically arranged on the drain outlet 110 along the center line of the drain outlet 110, and the two cover plates 200 have equal areas and consistent shapes. A torsion spring is also arranged between the two cover plates 200 and the hinged ear 210. When not under stress, the elastic force of the torsion spring abuts the two cover plates 200 to a position parallel to the ground, and the sum of the areas of the two cover plates 200 is equal to the area of the drain outlet 110. Therefore, when not under stress, the two cover plates 200 can close the drain outlet 110 under the elastic force of the torsion spring to prevent the odor in the drain pipe from emitting outward.
[0029] In this embodiment, a water tank 220 is further provided on the upper surface of each cover plate 200, and a drain port 230 is provided on the side of the water tank 220 away from the hinged ear 210, and the drain port 230 is connected to the water tank 220. In addition, a filter screen 300 is further provided just above the two cover plates 200, and the filter screen 300 can prevent foreign impurities from entering the drain pipe through the drain port 110 to cause the problem of clogging the drain pipe.
[0030] In the odor-proof drainage floor drain provided in the embodiment of the present application, when wastewater falls onto the cover plate 200 through the filter screen 300, the wastewater will enter the water storage tank 220 on the upper surface of the cover plate 200 for temporary storage. When the weight of the wastewater in the water storage tank 220 is greater than the elastic force of the torsion spring, the cover plate 200 will rotate downward to open the drain port 110, so that the wastewater can enter the drainage pipe through the drain port 230. When no wastewater passes through the floor drain, the two cover plates 200 will close the drain port 110 under the elastic force of the torsion spring, thereby effectively preventing the spread of odor.
[0031] In some embodiments, the upper surface of the floor drain housing 100 is provided with a hollow truncated cone structure 240, such as Figure 2 and Figure 3 As shown, in other words, the truncated cone structure 240 is placed upside down on the upper surface of the floor drain housing 100, and a hollow is provided at the axis of the truncated cone structure 240, so that the hollow of the truncated cone structure 240 coincides with the drain port 110. When waste water falls on the floor drain housing 100 through the filter screen 300, the waste water will gather at the hollow under the action of the truncated cone structure 240 to prevent the waste water from splashing outward.
[0032] In some embodiments, Figure 2-Figure 4 As shown, the bottom surface of the water storage tank 220 is provided with an inclined bottom surface 250, and the inclined bottom surface 250 is inclined from the side of the hinge ear 210 to the side of the drain port 230. Therefore, after the wastewater enters the water storage tank 220, it will flow to the drain port 110 through the drain port 230 under the structural effect of the inclined bottom surface 250, thereby improving the efficiency of discharging wastewater.
[0033] In some embodiments, Figure 2-Figure 4 As shown, a water retaining strip 260 is provided on one side of the drain port 230, and a plurality of water permeable holes 261 are provided along the thickness direction of the water retaining strip 260. With the above structural design, when the flow rate of wastewater is large, the speed of wastewater discharge can be slowed down by the water retaining strip 260 and the water permeable holes 261, so that the cover plate 200 can always be in an open state, so that wastewater can be directly discharged from the drain port 110 into the drain pipe.
[0034] In some embodiments, an outer edge of the water storage tank 220 is provided with an inclined surface 270 , and the inclined surface 270 is inclined toward one side of the drain outlet 110 , which can further facilitate the flow of wastewater into the drain outlet 110 .
[0035] In some embodiments, a retaining bar for installing the filter screen 300 is disposed at the drain outlet 110 . The outer diameter of the retaining bar is smaller than the outer diameter of the filter screen 300 . The retaining bar is used to support the filter screen 300 at the drain outlet 110 .
