[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] Example 1

[0042] Please refer to the following first. Figure 1 This utility model provides an odor-proof floor drain 10, which is used to prevent hair and other debris from clogging the sewer in the bathroom. The odor-proof floor drain 10 can quickly drain water into the sewer, prevent excessive water accumulation in the bathroom, and improve the air quality in the bathroom.

[0043] refer to Figure 2 and Figure 3 The odor-proof floor drain 10 includes a floor drain body 100, a water storage basket 200, and a water seal 300. The floor drain body 100 has a drainage chamber 110 inside. The water storage basket 200 and the water seal 300 are both located inside the drainage chamber 110. The floor drain body 100 has a drain outlet 120 on its side. The two opposite ends of the drain outlet 120 are connected to the drainage chamber 110 and the sewer, respectively. After the sewage generated in the bathroom enters the floor drain body 100, it exits from the water storage basket 200 and enters the sewer through the drain outlet 120.

[0044] refer to Figure 2 and Figure 3 It should be noted that the water storage basket 200 is provided with at least one first drain hole 210.

[0045] refer to Figure 2 and Figure 3 The water seal 300 has a first end 310 and a second end 320 opposite to each other. The first end 310 is connected to the drain body 100, and in the height direction of the drain body 100, the height of the second end 320 is higher than the height of the first drain hole 210.

[0046] In summary, in this application, the odor-proof floor drain 10 includes a floor drain body 100, a water storage basket 200, and a water seal 300. The water storage basket 200 is provided with at least one first drain hole 210. The water seal 300 has a first end 310 and a second end 320. The first end 310 is connected to the floor drain body 100, and in the height direction of the floor drain body 100, the height of the second end 320 is higher than the height of the first drain hole 210. When the floor drain body 100 discharges sewage, the sewage in the drain chamber 110 needs to accumulate to a level higher than the water seal 300 before the sewage can pass over the water seal 300 and be discharged into the sewer through the drain outlet 120. When the sewage in the drain chamber 110 is higher than the water seal 300, the sewage in the drain chamber 110 is also higher than the first drain hole 210. The sewage in the drain chamber 110 blocks the first drain hole 210. Therefore, the gas in the sewer cannot enter the bathroom through the first drain hole 210, which can effectively prevent odors and provide a good user experience.

[0047] refer to Figure 2 and Figure 3 It should be noted that in this embodiment, the water seal 300 is set as a flow interceptor 330, which is spaced apart from the drain outlet 120. The flow interceptor 330 has a first end 310 and a second end 320 along its height direction. The first end 310 is connected to the bottom of the drain body 100. When the water level in the drain body 100 is less than the height of the flow interceptor 330, the flow interceptor 330 can restrict the sewage in the drain body 100 from being discharged from the drain body 100. When the water level in the drain body 100 is higher than the height of the flow interceptor 330, the water in the drain body 100 passes over the second end 320 and flows into the sewer.

[0048] It should be noted that in this embodiment, the intercepting plate 330 and the drain body 100 are integrally formed. Since the drain body 100 is circular in shape and the intercepting plate 330 is rectangular, a gap may be created when the circular drain body 100 and the rectangular intercepting plate 330 are fitted together. If sewage flows out through the gap between the drain body 100 and the intercepting plate 330, the drain body 100 will not accumulate enough sewage to block the first drain hole 210, and sewer gas can enter the bathroom through the first drain hole 210. Therefore, by making the intercepting plate 330 and the drain body 100 integrally formed, this application minimizes the gap between them, enabling the odor-proof drain 10 to achieve its odor-proof effect. It is understandable that the interceptor plate 330 and the drain body 100 do not have to be set as an integral molded structure. Any scheme in which the water seal 300 is set as the interceptor plate 330 should be protected.

[0049] refer to Figure 2 and Figure 3The odor-proof drain 10 also includes a quick-cleaning structure 400, which is detachably connected to the drain body 100. The quick-cleaning structure 400 includes a decorative handle 410, an extraction rod 420, and a filter basket 430. At least part of the decorative handle 410 protrudes from the filter basket 430 in the height direction for extraction. The two ends of the extraction rod 420 are respectively connected to the decorative handle 410 and the filter basket 430. The filter basket 430 has at least one second drain hole 431, which connects to the first drain hole 210. When a certain amount of garbage accumulates in the quick-cleaning structure 400, the user can directly remove the quick-cleaning structure 400 and throw it into the trash can, then install a new quick-cleaning structure 400. Alternatively, the user can remove the quick-cleaning structure 400, clean the garbage from the filter basket 430, and reinstall the quick-cleaning structure 400 into the drain body 100, achieving a quick-cleaning effect. It's understandable that the quick-cleaning structure 400 doesn't have to be set up. Any solution that allows users to clean the garbage inside the odor-proof drain 10 should be protected.

[0050] refer to Figure 2 and Figure 4 The filter basket 430 has a third end 432 and a fourth end 433 along its height. The third end 432 is close to the extraction rod 420, and the fourth end 433 is provided with multiple first magnetic suction elements 434. The odor-proof drain 10 also includes an odor-proof core 500, which is provided with multiple second magnetic suction elements 510 and is connected to the fourth end 433. The first magnetic suction elements 434 are magnetically attracted to the second magnetic suction elements 510 to limit the movement of the filter basket 430 relative to the extraction rod 420. By the first magnetic suction elements 434 being magnetically attracted to the second magnetic suction elements 510, the filter basket 430 and the odor-proof core 500 can be magnetically attracted to each other, which can effectively prevent the filter basket 430 from being displaced by the water flow when the water flow is too large, thus preventing the filter basket 430 from failing to filter properly. It is understandable that, without considering inadequate filtration, the first magnetic suction component 434 and the second magnetic suction component 510 may not be required. Any solution that allows the filter basket 430 to filter waste should be protected.

[0051] It should be noted that the number of the first magnetic components 434 is matched with the number of the second magnetic components 510. In this embodiment, the number of both the first magnetic components 434 and the second magnetic components 510 is set to two. It can be understood that in other embodiments, the number of the first magnetic components 434 and the second magnetic components 510 can also be set to one or three. This utility model does not specifically limit the number of the first magnetic components 434 and the second magnetic components 510.

[0052] refer to Figure 2It should be noted that in this embodiment, the odor-proof core 500 is provided with a receiving groove 520, in which the aforementioned second magnetic member 510 is received. The odor-proof core 500 is also provided with a snap-fit ​​member 530, which snaps onto the wall of the receiving groove 520 to prevent the second magnetic member 510 from detaching from the receiving groove 520. It can be understood that, if the possibility of the second magnetic member 510 detaching from the receiving groove 520 is not considered, the snap-fit ​​member 530 may not be provided. Any scheme in which the odor-proof core 500 is provided with a second magnetic member 510 should be protected.

[0053] It should be noted that in this embodiment, the number of the first magnetic 434, the second magnetic 510, and the snap-fit ​​530 is set to two. It is understood that in other embodiments, the number of the first magnetic 434, the second magnetic 510, and the snap-fit ​​530 can also be set to one. Any scheme where the number of the first magnetic 434 corresponds to the number of the second magnetic 510, and the number of the snap-fit ​​530 corresponds to the number of the second magnetic 510, should be protected.

[0054] refer to Figure 2 It should be noted that in this embodiment, the decorative handle 410 and the extraction rod 420 are threadedly connected. The user can detach the decorative handle 410 from the extraction rod 420 by unscrewing it. Then, the user can flip the filter basket 430 and the extraction rod 420 to empty the waste from the filter basket 430. It is understood that the decorative handle 410 and the extraction rod 420 may not be threadedly connected. For example, they can be plugged in, snap-fitted, or integrally molded. Any solution that includes the decorative handle 410 and the extraction rod 420 in the quick-cleaning structure 400 should be protected.

[0055] It should be noted that the shape of the decorative handle 410 includes, but is not limited to, circles, squares, etc.

[0056] refer to Figure 2The quick-cleaning structure 400 also includes a connector 440, a third magnetic 450, and a fourth magnetic 460. The connector 440 is positioned between the filter basket 430 and the extraction rod 420. The opposite ends of the third magnetic 450 are magnetically attached to the extraction rod 420 and the connector 440, respectively. The opposite ends of the fourth magnetic 460 are magnetically attached to the filter basket 430 and the connector 440, respectively, thus enabling a detachable connection between the filter basket 430 and the extraction rod 420 for convenient operation. Users can flip the filter basket 430 by detaching it from the extraction rod 420 to remove the waste. It is understood that the connector 440, the third magnetic 450, and the fourth magnetic 460 can also be omitted; for example, the filter basket 430 and the extraction rod 420 can be threaded together. Any detachable connection scheme between the filter basket 430 and the extraction rod 420 should be protected.

[0057] By providing a detachable connection between the decorative handle 410 and the extraction rod 420, and a detachable connection between the extraction rod 420 and the filter basket 430, users can choose to detach the decorative handle 410 from the extraction rod 420 or detach the filter basket 430 from the extraction rod 420 when cleaning the garbage in the filter basket 430. This provides multiple options and makes operation convenient.

[0058] Example 2

[0059] refer to Figure 5 and Figure 6 The odor-proof floor drain 10 of this embodiment has a basically the same structure as the odor-proof floor drain 10 of Embodiment 1, the difference being the structure of the water seal 300. (See reference...) Figure 6 and Figure 7 The water seal 300 is configured as a sleeve 340, which is accommodated in the drain outlet 120. The sleeve 340 has a first end 310 and a second end 320 along its thickness direction. The first end 310 is connected to the inner wall of the drain outlet 120, and the second end 320 has a protrusion 321. In the height direction of the drain body 100, the height of the protrusion 321 is higher than the height of the first drain hole 210. When the water level in the drain body 100 is less than the height of the protrusion 321, the protrusion 321 can restrict the sewage from being discharged from the drain body 100. When the water level in the drain body 100 is higher than the height of the protrusion 321, the water in the drain body 100 passes over the second end 320 and flows into the sewer.

[0060] refer to Figure 5 and Figure 6It should be noted that in this embodiment, the water seal 300 also includes a threaded connector 350, which is engaged with the sleeve 340 to restrict movement of the threaded connector 350 relative to the sleeve 340. Simultaneously, the threaded connector 350 provides a sealing function between the inner wall of the drain outlet 120 and the sleeve 340, effectively reducing the gap between the sleeve 340 and the drain outlet, and effectively preventing the sleeve 340 from falling off, thus preventing water seal failure. It is understood that the threaded connector 350 can be omitted; any solution where the odor-proof drain 10 includes a sleeve 340 should be protected.

[0061] refer to Figure 7 It should be noted that in this embodiment, the sleeve fitting 340 is provided with a first locking block 341 and a second locking block 342. Both the first locking block 341 and the second locking block 342 extend circumferentially along the sleeve fitting 340. The first locking block 341 and the second locking block 342 are spaced apart, and the distance between the first locking block 341 and the second locking block 342 is set to the axial distance of the threaded connector 350, so as to restrict the threaded connector 350 from detaching from the sleeve fitting 340. It can be understood that if the detachment of the threaded connector 350 from the sleeve fitting 340 is not considered, the first locking block 341 and the second locking block 342 may not be provided. Any solution that allows the sleeve fitting 340 to be installed at the drain outlet 120 should be protected.

[0062] Example 3

[0063] refer to Figure 8 and Figure 9 The odor-proof floor drain 10 of this embodiment has a basically the same structure as the odor-proof floor drain 10 of Embodiment 1, the difference being the structure of the floor drain body 100. (See reference...) Figure 9 and Figure 10 In this embodiment, the odor-proof floor drain 10 is not designed as a concealed floor drain.

[0064] Example 4

[0065] refer to Figure 9 and Figure 11The odor-proof floor drain 10 of this embodiment has a basically the same structure as the odor-proof floor drain 10 of Embodiment 1, except that the structure of the filter basket 430 is different. The filter basket 430 is provided with two protrusions 435, which are spaced apart. The odor-proof core 500 is provided with a limiting part 540, and the two protrusions 435 are engaged with the opposite ends of the limiting part 540 in the width direction to limit the movement of the filter basket 430 relative to the extraction rod 420. By engaging the two protrusions 435 with the opposite ends of the limiting part 540, it is possible to effectively prevent the filter basket 430 from being displaced by the water flow when the water flow is too large, thereby preventing the filter basket 430 from failing to filter properly. It can be understood that, if inadequate filtration is not a concern, the protrusions 435 and the odor-proof core 500 can be omitted, as long as the filter basket 430 can filter garbage, the solution should be protected.

[0066] Example 5

[0067] refer to Figure 12 and Figure 13 The odor-proof floor drain 10 of this embodiment has a basically the same structure as the odor-proof floor drain 10 of Embodiment 1, except that the structures of the water storage basket 200 and the quick-cleaning structure 400 are different. The water storage basket 200 has a recessed locking groove 220, and the extraction rod 420 is locked in the locking groove 220. Since the water storage basket 200 has a recessed locking groove 220, that is, the side of the water storage basket 200 away from the extraction rod 420 is provided with a protrusion, the user can grasp the protrusion to extract the water storage basket 200, which is convenient to operate.

[0068] refer to Figure 12 and Figure 13 Because the side of the water storage basket 200 away from the extraction rod 420 has a protrusion, this side is uneven, affecting the aesthetics of the bathroom and making it inconvenient for users, as their feet may easily get stuck in the water storage basket 200. Therefore, the odor-proof floor drain 10 also includes a mounting cover 600, which is housed in the drain chamber 110. The floor drain body 100 is provided with a floor drain panel 130, which is arranged circumferentially along the floor drain body 100. The upper surface of the mounting cover 600 is flush with the surface of the floor drain panel 130, increasing the overall aesthetics of the bathroom and enhancing user safety. It is understandable that the mounting cover 600 could be omitted; any design in which the odor-proof floor drain 10 includes a water storage basket 200 should be protected.

[0069] refer to Figure 1 It should be noted that in other embodiments, the upper surface of the decorative handle 410 is flush with the upper surface of the drain panel 130.

[0070] refer to Figure 8 It should be noted that in other embodiments, the upper surface of the decorative handle 410 is flush with the upper surface of the mounting cover 600.

[0071] Example 6

[0072] refer to Figure 9 and Figure 11 The odor-proof floor drain 10 of this embodiment has a basically the same structure as the odor-proof floor drain 10 of Embodiment 1, except that the structure of the extraction rod 420 is different. The extraction rod 420 has a through hole 421 along its axial direction. The quick-cleaning structure 400 also includes an aromatherapy strip 470, which is accommodated in the through hole 421. The third magnetic member 450 abuts against the end of the aromatherapy strip 470 to prevent the aromatherapy strip 470 from detaching from the extraction rod 420.

[0073] Example 7

[0074] refer to Figure 14 The odor-proof floor drain 10 in this embodiment has a basically the same structure as the odor-proof floor drain 10 in Embodiment 3, the difference being the specific arrangement of the extraction rod 420 and the filter basket 430. In other embodiments, the extraction rod 420 and the filter basket 430 are configured as an integrally formed structure.

[0075] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
