Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] Embodiment 1:
[0035] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides an odor-proof floor drain, including: a floor drain shell 1, a floor drain cover 2, a dirt filter basket 3, a flow guide cover 41, a flexible sealing edge 42, a fixing part 43, a flow guide pipe 51, a counterweight block 61, a sealing plate 62 and a rotating shaft 63.
[0036] The floor drain cover plate 2 is detachably arranged on the inner side of the upper water inlet of the floor drain housing 1 .
[0037] The dirt filter basket 3 is detachably arranged inside the upper water inlet of the floor drain housing 1 and is located at the lower side of the floor drain cover plate 2 .
[0038] The deflector 41 is disposed at the lower side of the dirt filter basket 3 , and the top of the deflector 41 is fixedly connected to the bottom of the dirt filter basket 3 via the fixing member 43 .
[0039] The upper edge of the flexible sealing edge 42 is sealed to the lower edge of the air guide cover 41 .
[0040] The upper inner wall of the flow guide tube 51 is in contact with the lower outer wall of the flexible sealing edge 42 , and the upper end of the flow guide tube 51 extends obliquely upward and outward and is fixedly connected to the inner wall of the floor drain housing 1 .
[0041] The counterweight block 61 is fixedly connected to the sealing plate 62 , and the connection between the counterweight block 61 and the sealing plate 62 is rotatably connected to the water outlet at the lower end of the floor drain housing 1 through the rotating shaft 63 .
[0042] The sealing plate 62 is adapted to the shape of the water outlet at the lower end of the floor drain housing 1 .
[0043] Specifically, the floor drain cover 2 is provided with a plurality of cover filter holes, and the dirt filter basket 3 is provided with a plurality of filter basket filter holes, and the aperture of the cover filter hole is larger than the aperture of the filter hole of the filter basket.
[0044] In this embodiment, the floor drain cover 2 is clamped with the inner side of the upper water inlet of the floor drain shell 1, the dirt filter basket 3 is clamped with the inner side of the upper water inlet of the floor drain shell 1 and is located at the lower side of the floor drain cover 2, the fixing member 43 is a bolt, the upper edge of the flexible sealing edge 42 is sleeved with the lower edge of the guide cover 41, the upper end extension part of the guide pipe 51 is welded to the inner wall of the floor drain shell 1, and the connection between the counterweight block 61 and the sealing plate 62 is hinged to the lower water outlet of the floor drain shell 1 through the rotating shaft 63.
[0045] In this embodiment, the working principle of the odor-proof floor drain is as follows:
[0046] The initial state of the odor-proof floor drain is as follows: Figure 2As shown, the lever force provided by the gravity of the counterweight block 61 is greater than the lever force provided by the gravity of the sealing plate 62, so that the sealing plate 62 fits with the lower water outlet of the floor drain shell 1; when the odor-proof floor drain is draining, the water flows downward through the cover plate filter holes of the floor drain cover 2 and the filter basket filter holes of the dirt filter basket 3 in sequence, wherein impurities larger than the aperture of the cover plate filter holes are excluded from the outside of the odor-proof floor drain, and impurities smaller than the aperture of the cover plate filter holes and larger than the aperture of the filter basket filter holes are collected by the dirt filter basket 3; at this time, the water flows along the upper end extension portion of the guide pipe 51 and the guide cover 41 to the outer wall of the flexible sealing edge 42; as shown in FIG. Figure 1 As shown, under the action of water flow pressure, the flexible sealing edge 42 is deformed inward and separated from the upper inner wall of the guide tube 51, so that the water continues to flow downward through the inside of the guide tube 51; when the water reaches the lower water outlet of the floor drain shell 1, the sealing plate 62 rotates downward around the rotating shaft 63 under the action of the impact force of the water flow, and the water flows out of the odor-proof floor drain from the opening between the sealing plate 62 and the lower water outlet of the floor drain shell 1. After the drainage is completed, the odor-proof floor drain returns to the state as shown in FIG. Figure 2 In the state shown, the sealing plate 62 fits with the lower water outlet of the floor drain housing 1 , and the upper inner wall of the flow guide tube 51 fits with the lower outer wall of the flexible sealing edge 42 .
[0047] Specifically, when the sealing plate 62 fails, such as being deformed and unable to completely seal the water outlet, the backflow gas or liquid will generate pressure from the inside to the outside on the flexible sealing edge 42, making the lower outer wall of the flexible sealing edge 42 fit more closely with the upper inner wall of the guide tube 51, thereby preventing odor leakage and sewage backflow.
[0048] Exemplarily, the air deflector 41 is a curved surface structure whose diameter gradually increases from top to bottom, and the curved surface structure includes: an inverted cone surface, an inverted table surface, and a hemispherical surface.
[0049] Specifically, in this embodiment, the air deflector 41 adopts an inverted cone structure.
[0050] Exemplarily, the flexible sealing edge 42 is made of silicone or rubber material.
[0051] Specifically, in this embodiment, the flexible sealing edge 42 is made of silicone material.
[0052] Embodiment 2:
[0053] Exemplarily, the lower outer wall of the flow guide pipe 51 is fixedly connected to the water seal seat 52 via a plurality of connecting columns 53 .
[0054] The upper edge of the water seal seat 52 is higher than the lower edge of the flow guide pipe 51 .
[0055] Specifically, the difference between Example 2 and Example 1 is that Example 2 adds a water seal structure between the double reverse seals of the flexible sealing edge 42 and the sealing plate 62. When the water flows downward through the interior of the guide tube 51, it first reaches the interior of the water seal seat 52, then overflows from the upper edge of the water seal seat 52, and then reaches the lower water outlet of the floor drain shell 1. After the drainage is completed, the water seal seat 52 will store a water column of a certain height to prevent odor leakage and sewage backflow. At the same time, when the sealing plate 62 fails, such as deformation and unable to completely seal the water outlet, the water column in the water seal seat 52 can resist the change in the air pressure difference in the drainage pipe, and slow down the impact force of the reflux gas or liquid on the flexible sealing edge 42. The rest of the working principle of Example 2 is the same as that of Example 1.
[0056] Embodiment 3:
[0057] Exemplarily, a filter basket handle 31 is fixedly provided inside the dirt filter basket 3 .
[0058] Specifically, the difference between Example 3 and Example 1 is that a filter basket handle 31 is fixedly provided inside the dirt filter basket 3 in Example 3, which improves the convenience of cleaning the dirt filter basket. The rest of the working principle of Example 3 is the same as that of Example 1.
[0059] Exemplarily, a sealing ring 7 is provided at the lower side of the outer edge of the upper end of the floor drain housing 1 and at the outer wall of the floor drain housing 1 .
[0060] Specifically, in this embodiment, the sealing ring 7 is made of rubber material and is provided in a sleeve connection manner.
[0061] Embodiment 4:
[0062] Exemplarily, the contact parts between the floor drain cover plate 2 and the inner side of the upper water inlet of the floor drain housing 1 are both made of magnetic material.
[0063] Exemplarily, the contact parts between the dirt filter basket 3 and the inner side of the upper water inlet of the floor drain housing 1 are both made of magnetic material.
[0064] Specifically, the difference between Example 4 and Example 1 is that the contact part between the floor drain cover plate 2 of Example 4 and the inner side of the upper water inlet of the floor drain housing 1, and the contact part between the dirt filter basket 3 and the inner side of the upper water inlet of the floor drain housing 1 are all made of magnetic materials, so that the positions of the floor drain cover plate 2 and the dirt filter basket 3 will not shake easily, thereby improving the structural stability of the floor drain. The rest of the working principle of Example 4 is the same as that of Example 1.
[0065] The embodiment of the present application performs double sewage filtering through a floor drain cover and a sewage filter basket, and performs double reverse sealing through a flexible sealing edge and a sealing plate, thereby avoiding drainage blockage while improving the effect of preventing odor and sewage backflow.
[0066] The proposed deflector is a curved structure with a diameter that gradually increases from top to bottom, thereby improving drainage fluidity.
[0067] The lower outer wall of the proposed guide pipe is fixedly connected to a water seal seat by a plurality of connecting columns, and the upper edge of the water seal seat is higher than the lower edge of the guide pipe. By adding a water seal structure between the double reverse seal of the flexible sealing edge and the sealing plate, odor leakage and sewage backflow are further prevented. At the same time, when the sealing plate is damaged, the pressure difference change in the drainage pipe can be resisted, and the impact force of the reflux gas or liquid on the flexible sealing edge can be reduced.
[0068] The proposed dirt filter basket is fixedly provided with a filter basket handle inside, thereby improving the convenience of cleaning the dirt filter basket.
[0069] The proposed floor drain cover and the inner contact part of the upper water inlet of the floor drain shell are both made of magnetic material, and the dirt filter basket and the inner contact part of the upper water inlet of the floor drain shell are both made of magnetic material, thereby improving the structural stability of the floor drain.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
[0071] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
