[0052] Various specific embodiments of the present application will be described below with reference to the accompanying drawings which constitute a part of this specification. It should be understood that in the following drawings, the same parts use the same figure numbers.

[0053] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "upper", "lower", "left", "right", "inner", "outer", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description, and these terms are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0054] Figure 1A FIG. 1 is a perspective view of the first embodiment of the floor drain of the present application viewed from top to bottom, showing the external structure of the floor drain 100. Figure 1A As shown, the floor drain comprises a floor drain edge 102, a floor drain waist 104 and a weight bearing portion 106. The floor drain waist 104 is disposed between the floor drain edge 102 and the weight bearing portion 106, and connects the floor drain edge 102 and the weight bearing portion 106.

[0055] Specifically, Figure 1A As shown, the floor drain edge 102 is roughly annular. The floor drain edge 102 has an outer edge 112 and a circular inner edge 114. The floor drain waist 104 is roughly umbrella-shaped. The floor drain waist 104 extends inward and upward from the circular inner edge 114, and the far end of the floor drain waist 104 forms a waist edge 116. The weight bearing portion 106 is roughly disc-shaped. The weight bearing portion 106 is connected to the waist edge 116. The weight bearing portion 106 is located at the top of the floor drain. The weight bearing portion 106 is used to wrap the counterweight component 302 (see Figure 3 and Figure 6 ). The waist portion 104 of the floor drain extends upward to form a water leakage space 212 (see Figure 2 and Figure 6 ).

[0056] like Figure 1AAs shown, a leakage hole 123 is provided on the waist 104 of the floor drain. The leakage hole 123 is configured so that water can enter the leakage space 212 through the leakage hole 123. The leakage hole 123 includes a plurality of first waist through holes 124 and a plurality of second waist through holes 126. The first waist through holes 124 and the second waist through holes 126 penetrate the waist 104 of the floor drain in a vertical direction. In other words, the extension direction of the first waist through holes 124 and the second waist through holes 126 is approximately 90° to the lower surface of the floor drain edge 102. The cross-sectional area of ​​the first waist through hole 124 is different from the cross-sectional area of ​​the second waist through hole 126. In the first embodiment of the floor drain of the present application, the cross-sectional area of ​​the first waist through hole 124 is smaller than the cross-sectional area of ​​the second waist through hole 126. As Figure 1A As shown, a portion of the first waist through holes 124 is arranged near the floor drain edge 102 and is evenly arranged along the circumference of the floor drain. Another portion of the first waist through holes 124 is arranged into a plurality of groups 142. Each group 142 includes five first waist through holes 124. The plurality of groups 142 are evenly arranged along the circumference of the floor drain. The second waist through holes 126 are arranged between two adjacent groups 142. The first waist through holes 124 and the second waist through holes 126 enable the water flow outside the floor drain to flow downward along its gravity direction to enter the water leakage space 212, so as to be discharged as soon as possible.

[0057] It should be noted that, although the first embodiment of the floor drain of the present application shows that the water leakage hole 123 includes several first waist through holes 124 and several second waist through holes 126, those skilled in the art can understand that in other embodiments, the water leakage hole 123 may not include the second waist through hole 126. Those skilled in the art can also understand that at least one first waist through hole 124 and at least one second waist through hole 126 are within the protection scope of the present application.

[0058] In addition, if Figure 1A As shown, a groove 128 is also provided on the floor drain waist 104. The groove 128 is formed by being recessed downward from the upper surface of the floor drain waist 104 and is arranged around the weight bearing portion 106.

[0059] Figure 1B Yes Figure 1A The top view of the first embodiment of the floor drain of the present application is shown to better show Figure 1A The groove through hole 132 of the middle groove 128. Figure 1B As shown, a plurality of groove through holes 132 are also provided on the floor drain waist 104. The groove through holes 132 extend downward from the groove bottom (ie, the lower surface) of the groove 128 and penetrate the floor drain waist 104.

[0060] It should be noted that, although several groove through holes 132 are shown in the present application, at least one groove through hole 132 is within the protection scope of the present application.

[0061] Figure 2 Yes Figure 1A The first embodiment of the floor drain of the present application is shown in the bottom-up perspective view, showing the internal structure of the floor drain 100. Figure 2 As shown, the floor drain further includes a load-bearing reinforcement portion 204. The load-bearing reinforcement portion 204 is disposed on the floor drain waist portion 104 and the floor drain edge portion 102, and is located below the floor drain waist portion 104. The load-bearing reinforcement portion 204 is used to strengthen the connection strength between the floor drain waist portion 104 and the floor drain edge portion 102, thereby helping to maintain the water leakage space 212.

[0062] like Figure 2 As shown, the load-bearing reinforcement portion 204 includes several reinforcing ribs 205. Each of the several reinforcing ribs 205 is formed by extending radially along the floor drain, thereby connecting the floor drain waist 104 and the floor drain edge 102. The reinforcing ribs 205 are evenly arranged along the circumference of the floor drain. In the first embodiment of the floor drain of the present application, the several reinforcing ribs 205 are staggered with the first waist through hole 124 and the second waist through hole 126. In other words, in the vertical direction, the arrangement of the several reinforcing ribs 205 will not reduce the cross-sectional area of ​​the first waist through hole 124 and the second waist through hole 126, thereby not hindering the flow of water into the leakage space 212.

[0063] In addition, if Figure 2 As shown, the lower surface of the weight bearing portion 106 is provided with a hole 206 for connecting with the weight component 302 (see Figure 3 )Cooperate.

[0064] Figure 3 Yes Figure 1A The exploded view of the first embodiment of the floor drain of the present application is shown to illustrate the installation relationship and specific structure of the weight component 302 in the floor drain 100. Figure 3 As shown, the floor drain also includes a counterweight component 302. The counterweight component 302 is arranged on the weight bearing portion 106 and is arranged above the water leakage space 212. In the first embodiment of the floor drain of the present application, the weight bearing portion 106 wraps the counterweight component 302. Specifically, the cross-section of the counterweight component 302 is circular. The counterweight component 302 includes a counterweight body 312 that is roughly disc-shaped and a positioning rod 314. The positioning rod 314 is arranged below the counterweight body 312 and is connected to the counterweight body 312. The cross-section of the weight bearing portion 106 is circular. The counterweight body 312 and the positioning rod 314 are coaxially arranged with the weight bearing portion 106. The positioning rod 314 can extend into the hole 206 on the lower surface of the weight bearing portion 106 (see Figure 2) so that the heavy object bearing part 106 and the counterweight member 302 are relatively positioned. It can be understood that in other embodiments, the counterweight member 302 may not include the positioning rod 314. The density of the counterweight member 302 is greater than the densities of the floor drain edge part 102, the floor drain waist part 104, and the heavy object bearing part 106, so that the counterweight member 302 can apply gravity to the floor drain edge part 102. The weight G of the counterweight member 302 ranges from: 50g < G < 100g. When the floor drain is installed on the ground 722 (refer to Fig. 7A ), the weight of the counterweight member 302 can effectively keep the floor drain in place (i.e., stationary relative to the ground 722). In this application, the floor drain edge part 102, the floor drain waist part 104, and the heavy object bearing part 106 of the floor drain are integrally formed. The floor drain edge part 102, the floor drain waist part 104, and the heavy object bearing part 106 of the floor drain can be secondarily injection-molded on the counterweight member 302. As an embodiment, the floor drain edge part 102, the floor drain waist part 104, and the heavy object bearing part 106 are made of flexible materials. The counterweight member 302 can be made of metal or alloy.

[0065] As Figure 3 shown, several edge part through holes 304 are provided on the floor drain edge part 102. The several edge part through holes 304 are evenly arranged along the circumferential direction of the floor drain. The edge part through holes 304 extend along the radial direction of the floor drain and penetrate the floor drain edge part 102 substantially along the horizontal direction, so that water can enter the water leakage space 212 substantially along the horizontal direction through the edge part through holes 304.

[0066] Figure 4 is the bottom view of the first embodiment of the floor drain of this application as Figure 1A shown, to show the adsorption grooves 402 on the outer edge 102 in FIG. 1.

[0067] As Figure 4 shown, several adsorption grooves 402 are provided on the floor drain edge part 102. The several adsorption grooves 402 are evenly arranged along the circumferential direction of the floor drain. The adsorption grooves 402 are recessed upward from the lower surface of the floor drain edge part 102.

[0068] Figure 5 is the front view of the first embodiment of the floor drain of this application as Figure 1A shown, to show the specific structure and specific dimensions of the floor drain edge part 102 and the floor drain waist part 104.

[0069] As Figure 5 shown, the radius A of the outer edge 112 of the floor drain edge part 102 ranges from: 55mm < A < 100mm. The floor drain waist part 104 extends obliquely upward and inward from the circular inner edge 114 of the floor drain edge part 102, and the obliquely upward extension of the floor drain waist part 104 forms a water leakage space 212 that contracts upward (see Figure 2). Upward contraction refers to the tilted setting of the waist 104 of the floor drain, so that the water leakage space 212 shrinks upward, roughly in the shape of a trumpet. In other words, the inner edge of the waist 104 of the floor drain constitutes the outer edge of the water leakage space 212, so when the waist 104 of the floor drain is tilted, the outer edge of the water leakage space 212 gradually shrinks upward. More specifically, in the present embodiment, the waist 104 of the floor drain extends inward from the circular inner edge 114 of the floor drain edge 102 and is formed in the shape of an arc arch, and the waist 104 of the floor drain forms the upward contracted water leakage space 212 in the shape of an arc arch. The cross section of the waist 104 of the floor drain is an arc, and the arc has a center O. The center O is located below the floor drain, so that the waist 104 of the floor drain forms an arch away from the edge 102 of the floor drain. The value range of the radius R of the arc is: 60mm≤R≤90mm. The value range of the angle φ formed by the waist 104 of the floor drain and the horizontal plane is: 12°≤φ≤20°. More specifically, the value range of the angle φ formed by each point on the waist 104 of the floor drain and the horizontal plane (i.e., the lower surface of the floor drain edge 102) is: 12°≤φ≤20°. The value range of the total height K of the floor drain is: 15mm≤K≤20mm. The angle φ and the total height K of the floor drain can make the floor drain set on the ground 722 (see Fig. 7A ), while ensuring the water leakage space 212, the waist 104 of the floor drain has a slope, the total height of the floor drain is low, and the weight of the counterweight component 302 is heavy, thereby preventing people from kicking the floor drain.

[0070] Figure 6 Yes Figure 1A The cross-sectional view of the first embodiment of the floor drain of the present application is shown to illustrate the specific structures of the weight bearing portion 106 , the floor drain edge 102 and the floor drain waist 104 .

[0071] like Figure 6 As shown, the top surface of the weight bearing portion 106 is a cone protruding upward. When water drops on the top surface of the weight bearing portion 106, the water is guided downward by the inclined surface of the cone and slides outward into the groove 128, and then passes through the groove through hole 132 (see Figure 1B ) enters the water leakage space 212. The height H of the water leakage space 212 has a value range of 2mm≤H≤9mm. The height h of the counterweight component 302 has a value range of 5mm≤h≤7mm. It should be noted that the "height h of the counterweight component 302" in this application refers to the "height h of the counterweight body 312". The thickness T of the floor drain waist 104 has a value range of 2.3mm≤T≤2.6mm. In addition, the inner edge of the floor drain edge 102 (for example, the circular inner edge 114, see Figure 1A )The value range of radius B is: 48mm≤B≤85mm.

[0072] Fig. 7A702 is a schematic diagram of an application scenario of the first embodiment of the floor drain of the present application. The floor drain of the present application can be used in a shower room 702. Fig. 7A As shown, a faucet 712 is provided in the shower room 702. Water can flow out of the faucet 712. A drain hole 704 is provided on the floor 722 of the shower room 702. The faucet 712 is generally arranged above one side of the shower room 702 (for example, on a vertical wall). The drain hole 704 is generally arranged in the middle of the floor 722 of the shower room 702. In other words, the drain hole 704 is staggered with the faucet 712. In other words, the water flowing out of the faucet 712 will not directly flush the drain hole 704.

[0073] Figure 7B yes Fig. 7A The cross-sectional view of the ground 722 and the drain hole 704 is shown to illustrate the structure of the ground 722 and the drain hole 704. Figure 7B As shown, the ground 722 is inclined toward the drain hole 704, so that the water flowing out of the faucet 712 has a tendency to flow toward the drain hole 704. As an example, the drain hole 704 is a through hole. In other words, the drain hole 704 is the inlet of the drain pipe.

[0074] Figure 7C-7E is a perspective view of three types of cover plates, wherein the cover plates can be placed on Fig. 7A On the drain hole 704 shown. Figure 7C As shown, the first type of cover plate 771 is circular and covers the drain hole 704. The cover plate 771 is provided with a plurality of holes 781 of different sizes. The plurality of holes 781 are evenly arranged along the circumferential direction and roughly form two circles along the radial direction. The holes in the outer circle are larger and roughly petal-shaped. The holes in the inner circle are smaller and circular.

[0075] like Fig.7D As shown, the second type of cover plate 772 is circular and is disposed on the drain hole 704. The cover plate 772 is provided with a plurality of holes 782 of different sizes. The holes 782 are all circular holes. The plurality of holes 782 are evenly arranged along the circumferential direction and roughly form four circles along the radial direction. The holes in the three outer circles are larger than the holes located on the innermost side.

[0076] like Fig. 7E As shown, the third type of cover plate 773 is circular and covers the drain hole 704. The cover plate 773 is provided with a plurality of holes 783 of different sizes. The plurality of holes 783 are all strip-shaped, arranged substantially in parallel, and evenly spaced.

[0077] like Figure 7C-7E As shown, the cover plates on the drain hole 704 are generally in the shape of a flat plate. The holes provided on the cover plates allow water to flow into the drain hole 704. It is understood that any cover plate with any hole is within the protection scope of the present application.

[0078] The floor drain of the present application has good adaptability, and can be covered on various types of cover plates, or directly covered on the drain hole 704. When the floor drain is covered on the cover plate or the drain hole 704, the floor drain edge 102 can surround the cover plate or the drain hole 704 and contact the ground 722 around the drain hole 704.

[0079] It should be noted that the drain hole 704 of the present application is not provided with or does not have a protrusion protruding from the ground 722. For example, the drain hole 704 is not provided with a drain (not shown). The drain described herein refers to a drain including an openable portion. The openable portion has a drain in a closed state and an open state. For example, when the openable portion is in a closed state, the openable portion is roughly flush with the ground 722 and covers the drain hole 704, thereby realizing a water storage function. When the openable portion is in an open state, at least a portion of the openable portion protrudes from the ground 722 (for example, the openable portion can rotate relative to the ground 722 or move relative to the ground 722), and the drain hole 704 is opened, thereby realizing a drainage function.

[0080] Figure 7F The first embodiment of the floor drain of the present application covers Fig. 7A The schematic cross-sectional view of the drain hole 704 of the shower room 702 is shown to illustrate the matching relationship between the floor drain and the drain hole 704 .

[0081] like Figure 7FAs shown, when the floor drain covers the drain hole 704 of the shower room 702, the weight component 302 is approximately located in the middle of the drain hole 704 of the shower room 702. The waist portion 104 of the floor drain forms an arch away from the drain edge portion 102 and the load-bearing reinforcement portion 204 is arranged so that the gravity of the weight component 302 can be well transmitted to the drain edge portion 102, so that the drain edge portion 102 is attached to the ground 722 around the drain hole 704. In other words, the radius A of the outer edge 112 of the drain edge portion 102 is greater than the radius of the drain hole 704, so that the water leakage space 212 is arranged above the drain hole 704. The water leakage space 212 will not block the drain hole 704 or the hole on the cover plate, so that water can enter the drain hole 704 through the water leakage space 212 to ensure the drainage speed. When the floor drain covers the drain hole 704 of the shower room 702, since the drain hole 704 and the faucet 712 are staggered, the water flowing out of the faucet 712 will not directly flush the floor drain, but will form a layer of water surface on the ground 722. The water surface submerges the floor drain edge 102, thereby exerting a downward force on the floor drain edge 102 to keep the floor drain in place. In addition, since the floor drain edge 102 is made of a flexible material, when the water surface exerts a force on the floor drain edge 102, the floor drain edge 102 may undergo a certain deformation. While the lower surface of the floor drain edge 102 better fits the ground 722, the adsorption groove 402 (see Figure 4 ) is squeezed out of the adsorption groove 402. A vacuum is formed in the adsorption groove 402 so that the lower surface of the floor drain edge 102 adsorbs the ground 722. When the water flow is too large and the depth of the water surface increases, the water can be drained through the leakage holes 123 (for example, the first waist through hole 124 and the second waist through hole 126) on the floor drain waist 104. In more detail, since the leakage holes 123 (for example, the first waist through hole 124 and the second waist through hole 126) penetrate the floor drain waist 104 in the vertical direction, with the help of gravity, water can enter the leakage space 212 through the leakage holes 123 faster.

[0082] It should be noted that although the present application shows that the radius A of the outer edge 112 of the floor drain edge 102 is greater than the radius of the drain hole 704 so that the floor drain edge 102 is attached around the drain hole 704, in other embodiments, the radius A of the outer edge 112 may be equal to the radius of the drain hole 704 so that the floor drain edge 102 is attached to the drain hole 704.

[0083] In the prior art, existing floor drains include non-weighted floor drains and cap-type floor drains. Non-weighted floor drains are roughly in the shape of a piece of paper and are suitable for the drain hole in the shower room. Cap-type floor drains are roughly in the shape of a cap with a hollow portion and are used in basins or bathtubs with protrusions (e.g., drains). However, the inventors of the present application have found that, on the one hand, non-weighted floor drains cannot be applied to various types of cover plates, because no matter what kind of holes are provided on the non-weighted floor drain, they will overlap with at least a part of the holes on a certain type of cover plate, thereby reducing the flow area of ​​the water and slowing down the drainage speed. On the other hand, non-weighted floor drains cannot fit the ground well and are easily washed away by water flow, resulting in a large displacement. The inventors of the present application have also found that although the cap-type floor drain has a hollow portion to accommodate the protrusion, it is not suitable for the shower room. On the one hand, the cap-type floor drain is easily washed away by water flow, resulting in a large displacement. On the other hand, due to the high height of the cap-type floor drain, people in the shower room can easily kick the cap-type floor drain.

[0084]

[0085] Table 1

[0086] Table 1 shows the experimental comparison results of the floor drain of the present application relative to the unweighted floor drain and the cap-type floor drain. The water flow rate of the existing shower head is approximately 2-25.GPM (i.e., gallons per minute). At this speed, both the unweighted floor drain and the cap-type floor drain produce a large displacement, while the floor drain of the present application can remain in place relative to the drain hole 704. The maximum amount of water stored in the existing shower room is 1.9 liters. At this water storage, both the unweighted floor drain and the cap-type floor drain require a long time to start draining, while the floor drain of the present application reduces the time by nearly 3 seconds compared to the existing floor drain.

[0087] Figures 8A-8E The second embodiment of the floor drain of the present application is shown. Fig. 8A It is a three-dimensional view from top to bottom of the second embodiment of the floor drain of the present application. Figure 8B Yes Fig. 8A An exploded view of a second embodiment of a floor drain of the present application is shown. Figure 8C Yes Fig. 8A A top view of a second embodiment of a floor drain of the present application is shown. Fig.8D Yes Fig. 8A A front view of a second embodiment of the floor drain of the present application is shown. Fig. 8E Yes Fig. 8A A cross-sectional view of a second embodiment of a floor drain of the present application is shown. Figures 8A-8E The second embodiment shown is Figure 1A-Figure 6 The same points as the first embodiment shown will not be described in detail. Figures 8A-8E The second embodiment shown is Figure 1A-Figure 6 The main differences of the first embodiment shown are: first, Figure 1A-Figure 6The floor drain waist 104 of the floor drain shown in the figure forms an arch away from the floor drain edge 102, and Figures 8A-8E The drain waist 104 of the drain shown forms an arch toward the drain edge 102. Figures 8A-8E The floor drain shown also includes a blocking portion. Figures 8A-8E The water leakage hole 123 of the floor drain shown also includes a plurality of third waist through holes 812 .

[0088] Specifically, Fig. 8E As shown, the floor drain waist 104 extends inward from the circular inner edge 114 of the floor drain edge 102 and is formed in the shape of an arc arch, and the floor drain waist 104 forms a water leakage space 212 that shrinks upward in the shape of an arc arch. The value range of the height H of the water leakage space 212 is: 2mm≤H≤9mm. The cross section of the floor drain waist 104 is a circular arc, and the circular arc has a center O. The center O is located above the floor drain, so that the floor drain waist 104 forms an arch toward the floor drain edge 102. The value range of the radius R of the circular arc is: 60mm≤R≤90mm. The value range of the angle φ formed by the floor drain waist 104 and the horizontal plane is: 12°≤φ≤20°. More specifically, the value range of the angle φ formed by each point on the floor drain waist 104 and the horizontal plane (that is, the lower surface of the floor drain edge 102) is: 12°≤φ≤20°.

[0089] In addition, if Figures 8A-8E As shown, the floor drain also includes a blocking portion 802 for blocking foreign matter (for example, hair). The blocking portion 802 is arranged on the floor drain edge 102 and the floor drain waist 104, and is located above the floor drain edge 102 and the floor drain waist 104. More specifically, the blocking portion 802 includes a plurality of blocking ribs 803. The plurality of blocking ribs 803 are evenly arranged along the circumference of the floor drain. The blocking ribs 803 are formed to extend radially along the floor drain, thereby connecting the floor drain edge 102 and the floor drain waist 104. As a result, the blocking portion 802 can strengthen the connection strength between the floor drain waist 104 and the floor drain edge 102 while blocking foreign matter, thereby helping to maintain the water leakage space 212 (see Fig. 8E ).

[0090] In addition, if Figures 8A-8C As shown, the floor drain waist 104 of the floor drain is also provided with a plurality of third waist through holes 812. The plurality of third waist through holes 812 are arranged outside the plurality of first waist through holes 124 and the plurality of second waist through holes 126, and are evenly arranged along the circumference of the floor drain. The third waist through holes 812 penetrate the floor drain waist 104 in the vertical direction. In other words, the extension direction of the third waist through holes 812 is approximately 90° with the lower surface of the floor drain edge 102. Figures 8A-8EThe floor drain edge 102 of the second embodiment shown is not provided with a plurality of edge through holes 304, but is provided with a plurality of edge grooves 822. Specifically, a plurality of edge grooves 822 are provided on the floor drain edge 102. The edge grooves 822 are formed to be recessed downward from the upper surface of the floor drain edge 102, and the edge grooves 822 are provided to extend radially. The plurality of edge grooves 822 are provided corresponding to the plurality of third waist through holes 812. In other words, the edge grooves 822 are communicated with the third waist through holes 812, so that the water in the edge grooves 822 can enter the water leakage space 212 through the third waist through holes 812.

[0091] It should be noted that, although the blocking portion 802 is not provided in the first embodiment of the floor drain of the present application, those skilled in the art can understand that the blocking portion 802 can also be provided on the waist portion 104 of the floor drain of the first embodiment of the floor drain of the present application.

[0092] Fig. 9 The second embodiment of the floor drain of the present application covers Fig. 7A The schematic cross-sectional view of the drain hole 704 of the shower room 702 is shown to illustrate the matching relationship between the floor drain and the drain hole 704 .

[0093] like Fig. 9 As shown, when the floor drain covers the drain hole 704 of the shower room 702, the weight component 302 is approximately located in the middle of the drain hole 704 of the shower room 702. The weight component 302 applies gravity to the floor drain edge 102 so that the floor drain edge 102 is attached around the drain hole 704. That is, the radius A of the outer edge 112 of the floor drain edge 102 is greater than the radius of the drain hole 704, so that the water leakage space 212 is arranged above the drain hole 704. When the floor drain covers the drain hole 704 of the shower room 702, since the drain hole 704 and the faucet 712 are staggered, the water flowing out of the faucet 712 will not directly flush the floor drain, but will form a layer of water surface on the ground 722. The water surface submerges the floor drain edge 102, thereby applying a downward force to the floor drain edge 102 to keep the floor drain in place. Water flows through the edge groove 822 to the third waist through hole 812 , and enters the water leakage space 212 through the third waist through hole 812 .

[0094] It should be noted that although the cross-section of the waist 104 of the floor drain of the present application is an arc, in other embodiments, the cross-section of the waist 104 of the floor drain can be a plurality of smoothly connected arcs, or a plurality of smoothly connected curves, so that the waist 104 of the floor drain is configured to extend inward and obliquely upward to form a water leakage space that shrinks upward.

[0095] According to the application, it is understandable that, due to the floor drain waist 104 that is roughly flared and shrinks upwards, the circular counterweight component 302 can be suitably installed on the top of the floor drain. In addition, to the weight of the counterweight component 302, the height of the water-leaking space 212, the selection of the oblique angle of the floor drain waist 104, and the setting of the load-bearing reinforcement 204 on the floor drain 100, the floor drain 100 made of flexible material can stably cover the water-falling hole 704, the floor drain edge 102 is stably adsorbed on the periphery covering the water-falling hole 704, and the floor drain 100 made of flexible material is not deformed or produces slight deformation. Like this, although there is no water-leaking hole on the counterweight component 302 tops, water can still smoothly flow into the water-leaking space 212 through the hole of the leaking waist 104, and then flow into the water-falling hole 704.

[0096] It should be noted that the structure designed in this application is generally low in height and has sufficient drainage holes and drainage space. When selecting specific parameters for the structure designed in this application, the factors to be considered include the following:

[0097] (1) The floor drain 100 needs good drainage performance, but the inventor of the present application has observed that there are restrictions on the height of the floor drain 100 in some usage scenarios. For example, the floor drain 100 needs to be not easily washed away by running water, and the floor drain 100 needs to be prevented from being easily kicked by a bather and moved. Therefore, due to the height restriction of the floor drain 100, the present application will consider reasonably arranging the structure and area for drainage on the floor drain 100 under the condition of height restriction to maintain an optimized floor drain drainage space and drainage channel.

[0098] (2) Since the counterweight component 302 made of metal material is set on the top of the floor drain 100, and there is no drainage hole on the counterweight component 302, the present application needs to consider the limitation that there is no drainage hole on the top of the floor drain 100, and reasonably arrange the drainage structure and area on the floor drain 100 to maintain an optimized floor drain drainage space and drainage channel.

[0099] (3) Since the floor drain 100 is made of a flexible material (including at least one of silicone, rubber, TPE or ERP), and the thickness of the floor drain 100 shell is limited, the gravity of the weight component 302 will cause the floor drain 100 to have a tendency to deform. The present application will consider the reasonable arrangement of the structure of the floor drain 100 in the case of a flexible material and a weight component 302 on the top to maintain an optimized floor drain drainage space and drainage channel.

[0100] (4) In order to have a certain resistance to the impact of water flow, a counterweight component 302 is provided on the top of the floor drain 100 so that the floor drain 100 can be firmly attached to the supporting surface. However, an overweight counterweight component 302 will cause the floor drain 100 to deform. Therefore, the selection of the weight of the counterweight component 302 must take into account the impact on other structures of the floor drain 100. Therefore, the present application must consider optimizing the weight of the counterweight to maintain an optimized floor drain drainage space and drainage channel.

[0101] (5) In order to reduce the impact of water flow on the floor drain and increase the area of ​​the water flow hole, the present application should appropriately select the structure of the floor drain waist 104. For example, the arc radius R of the floor drain waist 104 is selected.

[0102] (6) In order to resist the impact of the water flow, the present application will appropriately design the shape of the outer edge of the floor drain. For example, the angle φ formed by each point on the waist 104 of the floor drain and the horizontal plane is selected.

[0103] Based on the above considerations, the present application selects several parameters of the floor drain 100 (including the floor drain material, the total height of the floor drain, the weight of the counterweight component, the thickness of the floor drain waist, the height of the counterweight component, the angle formed by the floor drain waist and the horizontal plane, the radius of the arc of the floor drain waist 104, and the radius of the inner edge of the floor drain edge). The ranges of these parameters are as follows:

[0104] The floor drain edge 102, the floor drain waist 104 and the weight bearing portion 106 of the floor drain 100 of the present application are made of flexible materials, which include at least one of silicone, rubber, TPE or ERP.

[0105] The weight component 302 may be made of metal or alloy. The alloy includes at least two of stainless steel, iron, and lead.

[0106] The value range of the total height K of the floor drain is: 15mm≤K≤20mm.

[0107] The weight G of the weight component 302 has a value range of: 50g <G<100g。

[0108] The thickness T of the floor drain waist 104 has a value range of 2.3 mm ≤ T ≤ 2.6 mm.

[0109] The height h of the weight component 302 has a value range of 5 mm ≤ h ≤ 7 mm.

[0110] The value range of the angle φ formed by the waist portion 104 of the floor drain and the horizontal plane is: 12°≤φ≤20°.

[0111] The value range of the radius R of the arc of the floor drain waist 104 is: 60mm≤R≤90mm.

[0112] The value range of the radius B of the inner edge of the floor drain edge 102 is: 48mm≤B≤85mm.

[0113] The parameters of the floor drain 100 in this application are as follows:

[0114] The total height K of the floor drain is 17 mm.

[0115] The weight G of the weight member 302 is 90 g.

[0116] The thickness T of the floor drain waist 104 is 2.4 mm.

[0117] The height h of the weight member 302 is 6 mm.

[0118] The angle φ formed between the floor drain waist 104 and the horizontal plane is 20°.

[0119] The radius R of the arc of the floor drain waist 104 is 80 mm.

[0120] The radius B of the inner edge of the floor drain edge 102 is 63 mm.

[0121] The radius A of the outer edge 112 of the floor drain edge 102 is 70 mm.
