DETAILED DESCRIPTION

[0030] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] Example 1

[0032] See also Figures 1 to 3 As shown, the utility model discloses a three-dimensional box-type floor drain, including a body 1 and a cover plate assembly 2, the cover plate assembly 2 is covered on the top of the body 1, and the cover plate assembly 2 includes a water inlet recess 21, and the water inlet recess 21 is lower than the top of the body 1, so as to form a sunken water inlet structure. The bottom surface of the water inlet recess 21 is provided with a plurality of lower water inlets 211 arranged at intervals, and the side wall of the water inlet recess 21 is provided with a plurality of side water inlets 212 arranged at intervals. The bottom surface and side wall of the water inlet recess 21 are respectively provided with a plurality of lower water inlets 211 and side water inlets 212 arranged at intervals, so that the structure between each adjacent lower water inlet 211 can play a role in intercepting slender debris such as hair or fiber. When the lower water inlet 211 is blocked due to the accumulation of slender debris and affects the water inlet, the water can be inlet through the side water inlet 212 higher than the lower water inlet 211, so as to prevent the debris from blocking and affecting the drainage. In addition, when the sewage discharged from the floor drain contains a large amount of foam, the foam with a smaller density will float up, and the foam has a certain viscosity. The side wall of the water inlet recess 21 can adhere to a certain amount of foam so that more foam is retained in the water inlet recess 21, which helps the sewage to be quickly drained into the sewer, and the foam adhered to the water inlet recess 21 can gradually dissipate.

[0033] The biggest difference between the cover plate assembly 2 of the utility model and the flat structure in the prior art is that the cover plate assembly 2 is a three-dimensional structure, and the water inlet recess 21 is designed to be lower than the top of the body 1 to form a sunken water inlet, and the water inlet recess is provided with a lower water inlet 211 and a side water inlet 212, thereby forming a three-dimensional water inlet combining the lower water inlet and the side water inlet. The problem that the water inlet of the existing flat water inlet structure is easily blocked by slender debris and foam is overcome, the water inlet speed of the floor drain is increased, and the ground drainage is accelerated.

[0034] Furthermore, the bottom surface and side walls of the water inlet recess 21 are both grid structures, the gaps of the grids arranged on the bottom surface of the water inlet recess 21 form the lower water inlet 211, and the gaps of the grids arranged on the side walls of the water inlet recess 21 form the side water inlet 212. The grid structure can effectively divert the water flow flowing into the water inlet recess 21 in the width direction, thereby effectively intercepting the slender debris mixed in the water flow. In other embodiments, only the bottom surface or the side wall of the water inlet recess 21 can be set as a grid structure.

[0035] See also Figures 3 to 6 As shown, in this example, the cover assembly 2 includes a water inlet member 201, and the water inlet member 201 is provided with a connection portion 22, and the water inlet recess 21 is arranged around the connection portion 22. The body 1 is provided with a support portion 11 for supporting the cover assembly 2, and the water inlet recess 21 is provided on one side of the support portion 11, and the water outlet 12 for connecting to the sewer pipe is provided on the other side of the support portion 11, so that a drainage channel is formed between the water inlet recess 21 and the water outlet 12, and the drainage channel is provided with a one-way valve 3, and the one-way valve 3 is used to cut off the fluid connection between the water inlet recess 21 and the water outlet 12, so as to form a first deodorizing structure. When the one-way valve 3 is opened, the water in the water inlet recess 21 flows out along the water outlet 12. Figure 3 and Figure 4 The water flows in the direction indicated by the arrow to the water outlet 12 and is discharged to the sewer of the building.

[0036] The connection part 22 of the water inlet member 201 is a circular structure, the support part 11 is also a circular structure, the water outlet 12 is arranged on the inner side of the support part 11 and located below the support part 11, and the water inlet recess 21 is located outside the support part 11. The support part 11 is provided with a first drain port 111, and a water retaining part 13 is arranged on one side of the support part 11 close to the water inlet recess 21, and the water retaining part 13 is located below the water inlet recess 21, and the water retaining part 13 is provided with a second drain port 131, and the water inlet recess 21 is connected to the water outlet 12 through the first drain port 111 and the second drain port 131. The one-way valve 3 is arranged on one side of the second drain port 131, and the one-way valve 3 is used to cover the second drain port 131 to close the second drain port 131, thereby cutting off the fluid communication between the water inlet recess 21 and the water outlet 12.

[0037] More specifically, the connection portion 22 of the water inlet member 201 is a circular flat plate structure, and the side wall of the water inlet recess 21 extends downward from the periphery of the connection portion 22, so the side wall of the water inlet recess 21 is also a circular structure. The support portion 11 is located on the inner side of the side wall of the water inlet recess 21, and supports the water inlet member 201 from below. There is a certain gap between the support portion 11 and the side wall of the water inlet recess 21, so that the sewage can be discharged from the gap. A bottom wall is provided on the outer side of the support portion 11 of the body 1, and the bottom wall is lower than the water inlet recess 21, so that the sewage flows downward through the water inlet recess 21 to the first drain port 111.

[0038] The support portion 11 is located on the inner side of the side wall of the water inlet recess 21, and the support portion 11 is a circular cylindrical structure, so the one-way valve 3 is arranged at the second drain port 131, so that the second drain port 131 is opened or closed by the movement of the one-way valve 3, thereby opening or cutting off the fluid communication between the water inlet recess 21 and the water outlet 12. In other embodiments, the one-way valve 3 may also be arranged at the first drain port 111, and the one-way valve 3 closes the first drain port 111 to cut off the fluid communication between the water inlet recess 21 and the water outlet 12.

[0039] Two water retaining plates 112 are provided on the outside of the support portion 11, and each water retaining plate 112 is provided with a second drain port 131, and both water retaining plates 112 are flat plate structures, which are easier to cooperate with the one-way valve 3 to form a first deodorizing structure than the arc-shaped support portion side wall. A water retaining cover 101 is also provided above the two water retaining plates 112, and the two water retaining plates 112 and the water retaining cover 101 cooperate to form the water retaining portion 13, and the water retaining cover 101 is arranged at a position lower than the water inlet recess 21, so that the sewage from the water inlet recess 21 flows to both sides of the water retaining cover 101, and then enters the internal space of the water retaining portion 13 through the second drain port 131. The first drain port 111 on the support portion 11 is arranged corresponding to the water retaining portion 13, so that after the sewage enters the water inlet recess 21, it passes through the second drain port 131 and the first drain port 111 in sequence and then is discharged from the water outlet 12 to the sewer.

[0040] The one-way valve 3 includes a shaft portion 31 and a valve body portion 32. The lower side of the shaft portion 31 is placed on the arc groove 1121 of the support portion 11. The arc groove 1121 is specifically arranged on the top of the water retaining plate 112, so that the arc groove 1121 plays a role in supporting the shaft portion 31 of the one-way valve 3. The upper side of the shaft portion 31 is pressed against the water retaining cover 101. In order to facilitate the rotation of the one-way valve 3, the lower side of the water retaining cover 101 is also provided with an arc groove, so that the water retaining plate 112 of the support portion 11 and the water retaining cover 101 cooperate to form a limit of the shaft portion 31 to prevent the one-way valve 3 from being separated from the water retaining plate 112 during the rotation process. The structure of the water retaining cover 101 and the water retaining plate 112 in cooperation with the limiting rotating shaft portion 31 makes it easy to install the one-way valve 3. During installation, the one-way valve is placed in the arc groove 1121 on the water retaining plate 112 and then the water retaining cover 101 is placed on top of the water retaining plate 112. On the other hand, it is also easy to disassemble and repair the one-way valve 3. The one-way valve 3 can be disassembled and repaired by simply opening the water retaining cover 101.

[0041] The valve body 32 of the one-way valve 3 is used to close or open the second drain port 131, and the valve body 32 is provided with a thickened structure 320, so that the one-way valve 3 automatically closes the second drain port 131 under the action of gravity. When there is water flow in the drainage channel, the water flow can overcome the gravity of the one-way valve 3 and push the one-way valve 3 open, thereby opening the second drain port 131.

[0042] The one-way valve 3 can play an anti-odor function, preventing the odor of the sewer from flowing back to the space above the floor drain through the water outlet 12, the drainage channel, and the water inlet groove 21. In addition, the inner wall of the body 1 and the outer wall of the support part 11 are respectively provided with a matching part 113, which is arranged between the two water retaining plates 112, and the matching part 113 abuts against the lower surface of the water retaining cover 101, thereby forming an anti-odor airtight structure between the water retaining cover 101 and the body 1 and its support part 11.

[0043] See also Figure 3As shown, the cover plate assembly 2 is arranged on the support portion 11 and covers the water outlet 12 in the radial direction. More specifically, the connection portion 22 of the cover plate assembly 2 covers the water outlet 12, and the water inlet 201 of the cover plate assembly 2 cooperates with the support portion 11 to form a second odor-proof structure. This prevents the odor of the sewer from directly overflowing upward from the water outlet 12 to the outside of the floor drain. The second odor-proof structure is formed by the top surface of the support portion 11 abutting against the lower side surface of the water inlet 201.

[0044] See also Figure 7 As shown, in one embodiment, the connection portion 22 is further provided with a connection hole 221 for installing a drain pipe. The drain pipe here refers to the drainage pipe of a sink, a washing machine, and other washing facilities. The drain pipe can be plugged into the connection hole 221 to discharge sewage directly to the water outlet 12, so that the floor drain of the utility model can realize the two-in-one function of ground drainage and water pipe drainage.

[0045] See also Figure 7 As shown, the cover assembly 3 also includes a decorative cover 202 arranged above the water inlet 201, and the decorative cover 202 is arranged above the connecting hole 221, and the water inlet 201 and the decorative cover 202 form a third deodorizing structure. For some places of use with only floor drainage, such as bathroom floor drainage, the connecting hole is not needed, and the odor from the sewer may overflow to the top of the floor drain through the water outlet 12 and the connecting hole 221. The third deodorizing structure between the water inlet 201 and the decorative cover 202 can prevent the odor from overflowing from the connecting hole 221, thereby achieving a deodorizing effect. The decorative cover 202 in this example is arranged on the periphery of the connecting portion 22 of the water inlet 201, and the third deodorizing structure is formed by the skirt at the side wall of the decorative cover 202 cooperating with the side wall of the water inlet 201. A step is arranged outside the connection hole 221 of the water inlet 201, and a groove is arranged on the lower surface of the decorative cover 202, thereby reducing the mating surface area between the water inlet 201 and the decorative cover 202, and preventing the formation of a water film between the water inlet 201 and the decorative cover 202, which makes it difficult to open the decorative cover 202. Fig.10 As shown, in other embodiments, the decorative cover 202 can cooperate with the step of the water inlet member 201, and a step is provided outside the connecting hole 221 of the water inlet member 201 to cooperate with the decorative cover 202 to form a third deodorizing structure.

[0046] It should be noted that the connection hole 221 is not necessary. For occasions where only ground drainage is required, it can be selected. Figure 3 The floor drain structure shown is not provided with a connecting hole 221.

[0047] See also Figures 1 to 10As shown, the water inlet part 201 of the cover assembly 2 is usually made of metal, so when the cover assembly 2 is taken in and placed, the metal collides with the ground and makes noise. In order to reduce the noise, a matching column 23 is provided at the bottom of the cover assembly 2. The matching column 23 is arranged at the bottom of the water inlet part 201, more specifically, at the bottom of the water inlet groove 21 and located at the outer edge of the water inlet groove 21. The matching column 23 is made of a softer material such as plastic, rubber or silicone, so as to reduce noise when the cover assembly 2 is taken in and placed.

[0048] See also Figure 3 and Figure 7 As shown, the bottom end of the body 1 is provided with a matching flange 14, the inner wall of the matching flange 14 is used to connect and cooperate with a small-diameter sewer pipe, and the outer wall of the matching flange 14 is used to connect and cooperate with a large-diameter sewer pipe. In order to facilitate plugging, a guide flange 15 is provided on the inner side of the matching flange 14, the space between the matching flange 14 and the guide flange 15 is used to plug in a small-diameter sewer pipe, and the outer side of the matching flange 14 is used to plug in a large-diameter sewer pipe, so as to adapt to sewer pipes of different specifications.

[0049] The main body 1 is a square box-shaped structure, with a water outlet 12 arranged in the middle and a water inlet groove 21 arranged around the water outlet 12, thereby forming a structure in which water flows in from all sides to the middle, and the overall layout is more reasonable.

[0050] Example 2

[0051] See also Figures 8 to 9 As shown, the difference between this embodiment and embodiment 1 is that the connection portion 22 of the cover plate assembly 2 is a square structure, and the support portion 11 is also a square structure. Therefore, the side wall of the support portion 11 is a flat plate structure, which is easy to cooperate with the one-way valve 3 to form a first deodorizing structure. Specifically, the support portion 11 is provided with a first drain port 111 for connecting the water inlet recess 21 and the water outlet 12, and the one-way valve 3 is arranged on one side of the support portion 11, and the one-way valve 3 is used to cover the first drain port 111 to close the first drain port 111, thereby cutting off the fluid communication between the water inlet recess 21 and the water outlet 12. Among them, the two opposite side walls of the support portion 11 are respectively provided with a first drain port 111, and each first drain port 111 is respectively provided with a one-way valve 3 for opening or closing the first drain port 111. The rotating shaft portion 31 of the one-way valve 3 relies on the arc groove of the support portion 11 and the water inlet member 201 of the cover plate assembly 2 to achieve position limiting.

[0052] See also Figures 9 and 10 As shown, the structure of the cover plate assembly 3 is the same as that of the embodiment 1 in that it can be used only for floor drainage without a connection hole, or it can be used for floor drainage and water pipe drainage with a connection hole 221, and a decorative cover 202 is provided to close the connection hole. The decorative cover 202 cooperates with the water inlet 201 to form a third deodorizing structure.
