Description

Technical Field

[0001] The present application relates to the technical field of drainage, and in particular to a floor drain cover and an anti-odor floor drain. Background Art

[0002] Floor drains are common drainage components and are installed in many places where water is frequently used. Because floor drains are installed on drain pipes, and sewage inside the drain pipes may flow back and return air, many floor drains are currently designed to prevent odor from backflow and return air from causing adverse effects on the environment.

[0003] At present, odor-proof floor drains mainly use floats, one-way valves and water seals. Among them, the float-type floor drain has the simplest structure and is therefore least likely to fail. After a float is set in the floor drain, the water flowing down from above will lift the float, exposing the drain outlet. However, when backflow or backgas occurs, the float will also be lifted up under pressure or buoyancy, resulting in a significant reduction in the sealing effect. For this reason, CN106638911A sets a floor drain cover above the float, and the float is pressed tightly by the weight of the floor drain cover to achieve a good seal of the float.

[0004] However, the floor drain cover in the above patent needs to be turned over to achieve a sealing effect, and the floor drain cover is generally dirty, so the turning operation is very inconvenient. Utility Model Content

[0005] The embodiments of the present application provide a floor drain cover and an odor-proof floor drain, which are used to solve the problem of the inconvenience of flipping over the floor drain cover in the prior art.

[0006] On the one hand, an embodiment of the present application provides a floor drain cover, including a cover body, and further comprising:

[0007] A connecting ring is sleeved on the outside of the cover body, and the outer side of the connecting ring is used to connect with the floor drain;

[0008] A flap is vertically rotatably arranged on the top surface of the connecting ring, and when the flap is rotated to a horizontal position, it is above the cover body, and the flap is in contact with the cover body;

[0009] The floating plate is arranged at the end of the flap. The floating plate is made of a material with a density less than that of water. When draining water, the floating plate drives the flap to rotate upward, so that the cover body can be lifted up under the buoyancy of the float in the floor drain.

[0010] In a possible implementation, a drainage hole is provided on the cover body.

[0011] In a possible implementation, drainage holes are also provided on the flap and the floating plate.

[0012] In a possible implementation, an external thread is provided on the outer side surface of the connecting ring, and the external thread is used to be threadedly connected with the internal thread on the side surface of the floor drain.

[0013] On the other hand, an embodiment of the present application also provides an odor-proof floor drain, including a top plate and a drainage cylinder, a float is arranged inside the drainage cylinder, and also includes the above-mentioned floor drain cover. The odor-proof floor drain also includes a placement cylinder, which is connected between the top plate and the drainage cylinder, and the floor drain cover is arranged in the placement cylinder.

[0014] In a possible implementation, in a sealed state, the top surface of the top plate is flush with the top surface of the flap in the floor drain cover.

[0015] In a possible implementation, a water retaining ring is provided on the inner side of the drainage tube, and the float is inserted into the water hole in the center of the water retaining ring.

[0016] A floor drain cover and an anti-odor floor drain in the present application have the following advantages:

[0017] A flap is arranged above the cover body, and a floating plate is arranged at the end of the flap. When draining water, the floating plate can drive the flap to rotate upward under the action of buoyancy, thereby increasing the activity space of the cover body, so that the float together with the cover body can move upward under the buoyancy of water to expose the water hole; when air or water return occurs, the flap can exert sufficient pressure on the cover body to prevent the cover body and the float from moving upward, thereby effectively improving the sealing of the floor drain, and the drainage and sealing states do not need to be switched manually.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. 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.

[0024] Figure 1-3 A schematic diagram of the structure of an odor-proof floor drain with a floor drain cover provided in an embodiment of the present application. The embodiment of the present application provides a floor drain cover, including a cover body 500, and also including:

[0025] The connecting ring 420 is sleeved on the outside of the cover body 500, and the outer side of the connecting ring 420 is used to connect with the floor drain;

[0026] The flap 400 is vertically rotatably arranged on the top surface of the connecting ring 420. When the flap 400 rotates to a horizontal position, it is above the cover 500, and the flap 400 contacts the cover 500.

[0027] The floating plate 410 is arranged at the end of the flap 400. The floating plate 410 is made of a material with a density less than that of water. When draining water, the floating plate 410 drives the flap 400 to rotate upward, so that the cover body 500 can be lifted up under the buoyancy of the float 600 in the floor drain.

[0028] Exemplarily, the connecting ring 420 is preferably a circular ring, whose outer diameter is equivalent to the inner diameter of the floor drain, and the inner diameter is equivalent to the outer diameter of the cover body 500. During installation, the connecting ring 420 is first installed on the top of the floor drain, and then the cover body 500 is installed. After the installation is completed, the flap 400 and the floating plate 410 are a whole, and the cover body 500 is covered to apply pressure to the cover body 500 to prevent the float 600 and the cover body 500 from being easily lifted up during return air or backflow.

[0029] The flap 400 can be rotatably connected to the top surface of the connecting ring 420 via a rotating shaft, so that the flap 400 can rotate vertically above the cover 500. In the embodiment of the present application, the connection between the flap 400 and the connecting ring 420 is located at a position close to the outer side of the connecting ring 420, so when the cover 500 is installed inside the connecting ring 420, the contact point between the cover 500 and the flap 400 when the cover 500 moves upward is the top of the outer side of the cover 500, and the distance between the contact point and the rotating shaft is less than the sum of the lengths of the flap 400 and the floating plate 410, so when the cover 500 pushes the flap 400 upward, a lever will be formed, and the cover 500 needs to apply a large force to push up the flap 400, which effectively improves the sealing performance of the float 600. During normal drainage, water first submerges the flap 400 and the float 410. Since the float 410 is made of a material with a density less than that of water, the float 410 will float upward under the buoyancy, thereby driving the flap 400 to rotate upward. At this time, the activity space of the cover 500 is increased. After the water flows to the bottom of the cover 500, the float 600 will be affected by the buoyancy of the water and float upward, driving the cover 500 to move upward together, thereby exposing the water hole and allowing water to flow out from the water hole.

[0030] Furthermore, since the floor drain cover in the present application is usually installed on the ground, there is a possibility of being stepped on, and the density of the floating plate 410 is relatively small, in order to prevent the floating plate 410 from being stepped on, a protective layer can be wrapped on the outside of the floating plate 410. The thickness of the protective layer needs to be relatively small, but the strength should be large enough to allow the floating plate 410 to be filled in the protective layer as much as possible, thereby reducing the influence of the weight of the protective layer on the buoyancy of the floating plate 410.

[0031] In the embodiment of the present application, a drainage hole is provided on the cover 500. It should be understood that the density of the float 600 in the present application is less than that of water, and the density of the cover 500 and the flap 400 should not be too large. On the premise of ensuring sufficient strength, the density of the cover 500 and the flap 400 also needs to be relatively small. It is preferred that materials such as PPR or PVC can be used. Even if the density is slightly greater than that of water, under the action of the large buoyancy provided by the float 600, the cover 500 and the flap 400 will move upward or rotate during the drainage process. During the drainage process, the water on the ground can flow to the bottom of the cover 500 through the drainage hole on the cover 500, thereby generating buoyancy on the float 600.

[0032] Furthermore, drainage holes are also provided on the flap 400 and the floating plate 410. Since the flap 400 and the floating plate 410 will rotate upward during drainage, so that water will flow directly to the bottom of the flap 400 and then continue to flow downward from the drainage holes on the cover 500, the drainage holes on the flap 400 and the floating plate 410 are not necessary, but after the drainage holes are provided, it can be ensured that water can be discharged smoothly at the beginning of drainage before the floating plate 410 and the flap 400 start to rotate upward, thereby avoiding water accumulation.

[0033] Further, the outer surface of the connecting ring 420 is provided with an external thread, which is used to be screwed with the internal thread on the side of the floor drain. In addition to the threaded connection, for the connecting ring 420 and the floor drain with a quadrilateral horizontal cross section, the connecting ring 420 can also be installed in the floor drain by a clamping method.

[0034] Based on the above floor drain cover, an embodiment of the present application also provides an odor-proof floor drain, including a top plate 100 and a drainage tube 300, a float 600 is arranged inside the drainage tube 300, and also includes the above-mentioned floor drain cover. The odor-proof floor drain also includes a placement tube 200, which is connected between the top plate 100 and the drainage tube 300, and the floor drain cover is arranged in the placement tube 200.

[0035] Exemplarily, the diameter of the top plate 100 is larger than that of the placing tube 200, and the outer diameter of the placing tube 200 is the same as the inner diameter of the top plate 100. When the top of the outer side surface of the placing tube 200 is connected to the bottom end of the inner circle of the top plate 100, a space for placing the connecting ring 420 and the cover body 500 is formed under the top plate 100. After the cover body 500, the connecting ring 420, the flap 400 and the floating plate 410 are all installed inside the placing tube 200, the top surface of the flap 400 is flush with the top surface of the flap 400, or even slightly lower than the top plate 100, so that water can flow normally to the top of the flap 400.

[0036] Furthermore, the outer diameter of the drainage tube 300 is the same as the inner diameter of the placement tube 200. When the top of the outer side surface of the drainage tube 300 is connected to the bottom of the inner side surface of the placement tube 200, a space for water flow is formed inside the drainage tube 300.

[0037] Furthermore, a water retaining ring 310 is provided on the inner side of the drain cylinder 300, and the float 600 is inserted into the water hole in the center of the water retaining ring 310. The water retaining ring 310 is a ring-shaped structure connected to the inner side of the drain cylinder 300, and a water hole is provided in the center thereof. The float 600 adopts a structure that is larger at the top and smaller at the bottom, and the cross section of the position where it contacts the water hole is the same shape and size as the water hole, so when the float 600 is inserted into the water hole, the float 600 can completely block the water hole to avoid backflow or return of air due to poor sealing.

[0038] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. 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.

[0039] 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.
