[0034] As Figures 1 to 8 shown, a combined odor-proof floor drain in this embodiment includes an upper floor drain body 1 and a lower floor drain body 2. The upper end of the lower floor drain body 2 is sleeved and threadedly connected to the lower end of the upper floor drain body 1. A water leakage port with an opening direction facing obliquely downward is provided at the lower end of the lower floor drain body 2. A partition board 11 covers the water leakage port. The upper end of the partition board 11 is hinged to the upper end of the water leakage port through a reset assembly. A vertically arranged drip plate 3 is provided at the lower end of the water leakage port. The lower end of the partition board 11 abuts against one side of the upper end of the drip plate 3.
[0035] AsFigure 1 and Figure 2 As shown in Figure 2 , the reset component of this embodiment includes a hinge block 12 and a torsion spring 13. A hinge block 12 is provided on the lower floor drain body 2 outside the water leakage port. One end of the partition plate 11 is provided with a hinge shaft 14. The hinge shaft 14 is rotatably connected to the hinge block 12. A torsion spring 13 is sleeved on the hinge shaft 14. One end of the torsion spring 13 abuts against the lower floor drain body 2 outside the water leakage port, and the other end of the torsion spring 13 abuts against the outer side wall of the partition plate 11. By providing the hinge block and the torsion spring, it is convenient for the partition plate to open and close automatically. The protruding hinge shafts 14 can be provided on both sides at one end of the partition plate 11, two hinge blocks 12 can be provided, and the two hinge shafts are respectively rotatably connected in the two hinge blocks 12. A gap is reserved between the partition plate 11 and the corresponding hinge block 12 for installing the torsion spring.
[0036] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , the hinge shaft 14 of this embodiment is arranged perpendicular to the central axis of the lower floor drain body 2, and the hinge shaft 14 is arranged parallel to the partition plate 11.
[0037] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , the lower floor drain body 2 of this embodiment includes a bowl-shaped pipe section 21, a straight pipe section 22, and a bent pipe section 23 that are integrally connected in sequence. An external thread 24 is provided on the outer side wall of the bowl-shaped pipe section 21, and an internal thread adapted to the external thread 24 is provided on the inner side wall at the lower end of the upper floor drain body 1; the lower end end face of the straight pipe section 22 has an installation area, and the other part of the lower end end face of the straight pipe section 22 is integrally connected to the bent pipe section 23, and the hinge block 12 is fixed on the outer side wall of the installation area. The use of the bent pipe section can effectively prevent odors.
[0038] As Figure 3 shown in Figure 3 , a preferred solution of this embodiment is that the length of the drip plate 3 is not less than the outer diameter of the water leakage port, and the upper end of the drip plate 3 is a circular arc structure adapted to the outer side wall at the bottom of the bent pipe section 23. It can facilitate the effective dripping of the water at the water leakage port.
[0039] Preferably, a leak-proof rubber ring is provided in the groove of the external thread 24. The setting of the leak-proof rubber ring is beneficial to the sealed connection between the upper floor drain body and the lower floor drain body.
[0040] An alternative solution of this embodiment is that the inclination angle of the partition plate 11 is 45°, and a filter plate 25 is further provided at the upper end of the lower floor drain body 2.
[0041] Optionally, the partition plate 11 of this embodiment is a circular plate, a rubber pad is provided on the inner side surface of the partition plate 11, and the partition plate 11 can completely block the water leakage port.
[0042] As Figure 1 and Figure 4 shown, a specific solution of this embodiment is that the upper floor drain body 1 includes a first pipe body 15 and a second pipe body 16. The inner diameter of the first pipe body 15 is larger than the outer diameter of the second pipe body 16. The lower end of the first pipe body 15 is a closed-end structure, and the lower end of the second pipe body 16 is a closed-end structure. The upper end of the second pipe body 16 is hermetically fixed to the lower end of the first pipe body 15. The upper end of the lower floor drain body 2 is sleeved and threadedly connected to the lower end of the second pipe body 16, and the upper end of the lower floor drain body 2 is lower than the lower end of the first pipe body 15.
[0043] As Figure 5 and Figure 6 shown, a grate 17 covers the upper end of the first pipe body 15 of this embodiment, and a filter net 18 covers the upper end of the second pipe body 16. Adopting a multi-layer filtering structure can effectively filter and prevent the drain pipe from being blocked.
[0044] The filter plate 25 of this embodiment can adopt a structural form in which a plurality of petal-shaped structures are arranged in the middle of an annular plate, as Figure 7 shown.
[0045] Specifically, a first step can be provided on the inner side of the upper end of the first pipe body 15 to place the grate 17 on the first step; a second step can be provided on the inner side of the upper end of the second pipe body 16 to place the filter net 18 on the second step.
[0046] An outer edge of the upper end surface of the first pipe body 15 of this embodiment is provided with a panel 19 to facilitate adaptation to the top opening of the sewer.
[0047] The upper floor drain body 1 of this embodiment is made of SUS304 stainless steel, the lower floor drain body 2 is made of plastic, and the torsion spring is made of corrosion-resistant stainless steel. The panel thickness is 2 mm, the grating thickness is 1 mm, and the filter screen thickness is 1 mm. The upper structure is integrally die-cast, the grating and the filter screen are rolled, and the lower structure is integrally formed by plastic casting. The top is provided with a filter plate, and the bottom of the lower floor drain body is provided with a drip plate, which is mainly used for draining water and removing the remaining water droplets. When installing this device, the lower floor drain body is sleeved into the bottom through-hole position of the upper floor drain body, and the threaded part of the lower floor drain body is screwed into the upper floor drain body so that its rubber ring and thread are closely attached to the bottom through-hole. Then, the device is installed at a position with a drain pipe 4, and ceramic tiles are pasted around for fixation. When in use, the flowing water will flow into the anti-odor floor drain through the grating, and then flow through the grating, the filter screen, and the filter plate to the drain pipe 4. When the water flows to the partition plate position, the partition plate of the anti-odor floor drain will automatically open with the gravity of the flowing water during drainage. After the water is drained, the partition plate will be automatically closed with the assistance of the torsion spring. During this period, the drained water and the remaining flowing water will flow to the drain pipe 4 along the drip plate. After the overall drainage is completed, the partition plate closes to automatically block the odor in the drain pipe 4 from returning to the room along the floor drain. This device is equipped with three filter screens, which can effectively block sundries and other things from entering the drainage pipe and affecting the drainage performance. The whole device is easy and flexible to install, effectively blocks the return of odor, and the device itself is relatively long, which can be well inserted into the bottom drain pipe, effectively solving the problem of the formation of a fault due to the low elevation of the drain pipe.
[0048] In this embodiment, by using the combined structure of the upper floor drain body 1 and the lower floor drain body 2, the problems of easy odor return and insufficient length to form a fault of the floor drain are solved and optimized by its flexible and convenient operation.
[0049] The combined anti-odor floor drain of this embodiment, during the decoration and construction, effectively and perfectly solves the problems of easy odor return and insufficient length to form a fault of the floor drain through its own advantages. At the same time, by optimizing the construction process, the installation speed, reliability, and stability of the floor drain are improved.
