[0011] Optionally, the reset structure includes a first magnetic component and a second magnetic component. One of the first magnetic component and the second magnetic component is disposed on the filter element body, and the other is disposed on the baffle. The first magnetic component and the second magnetic component reset the baffle by means of the principle that opposite magnetic poles attract each other or like magnetic poles repel each other.
[0012] Optionally, the odor-blocking filter element further includes a sealing gasket disposed on the side of the baffle facing the filter element body, the sealing gasket being able to abut against the periphery of the bottom opening of the filter element body when the baffle seals the bottom opening of the filter element body.
[0013] Optionally, the odor-blocking filter element further includes a sealing ring, which is sleeved on the filter element body and sandwiched between the filter element body and the inner wall of the pipe below the drain outlet of the toilet body.

[0016] Optionally, the odor-blocking component further includes a drain plug, which has multiple water passage holes and is located at the top opening of the filter element body. The drain plug and the odor-blocking filter element are an integral structure.
[0017] Optionally, the water seal assembly further includes a drain pipe, and the outlet of the water seal bend is connected to the drain pipe.
[0018] According to another aspect of the present invention, a urinal is provided, comprising a urinal body and an odor-proof structure as described in any of the preceding claims.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides an odor-proof structure comprising a water seal component and an odor-blocking component. The water seal bend forms a trap after flushing, preventing air from rising from the sewer and creating the first odor barrier. Simultaneously, the water inlet of the water seal bend connects to the drain outlet of the toilet bowl. The odor-blocking component is located at the drain outlet of the toilet bowl and connects to the water seal bend. The side of the odor-blocking component facing the bowl is the inlet side, and the side facing the water seal bend is the drain side. The odor-blocking component allows fluid to flow from the inlet side to the drain side and prevents backflow. In other words, the odor-blocking component allows fluids (such as urine, flushing water, or odors) to flow in one direction, preventing backflow and thus creating a second odor barrier. With the combined effect of the odor-blocking component and the water seal bend, this odor-proof structure effectively prevents sewer odors from rising, providing excellent odor control, significantly reducing odor volatilization, creating a hygienic environment, and improving the user experience.
[0021] The urinal provided by this utility model adopts the above-mentioned odor-proof structure, which has a good odor-proof effect and a good user experience. Attached Figure Description

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0039] This embodiment provides a urinal, such as Figure 1 As shown, the urinal includes a toilet bowl body 100 and an odor-proof structure provided in this embodiment. The toilet bowl body 100 has a drain outlet 101 at its lowest point in the direction of gravity on its surface 103. The drain outlet 101 communicates with the sewer to facilitate the discharge of fluids (such as urine, flushing water, or odors). The odor-proof structure is located between the drain outlet 101 of the toilet bowl body 100 and the sewer, preventing odors from rising from the sewer and improving the user experience.
[0040] like Figure 1 and Figure 2As shown, the odor-proof structure provided in this embodiment includes a water seal assembly 1 and an odor-blocking assembly 2. The water seal assembly 1 includes a water seal bend 11, which has an inlet 111 and an outlet 112, forming a U-shaped water trap 113 between the inlet 111 and the outlet 112. The water trap 113 can form a water trap after the user flushes, preventing odors from rising from the sewer and forming the first odor-proof barrier.
[0041] Meanwhile, the water seal assembly 1 also includes a drain pipe 12, and the outlet 112 of the water seal bend 11 is connected to the drain pipe 12. The outlet 112 of the water seal bend 11 is connected to the sewage channel in the sewer through the drain pipe 12, thereby discharging fluid.
[0042] Continue to refer to Figures 1-2 The inlet 111 of the water seal bend 11 is connected to the drain outlet 101 of the toilet body 100. The odor-blocking component 2 is installed at the drain outlet 101 of the toilet body 100 and is connected to the water seal bend 11. The side of the odor-blocking component 2 facing the pot surface 103 of the toilet body 100 is the sewage inlet side, and the side of the odor-blocking component 2 facing the water seal bend 11 is the sewage outlet side. The odor-blocking component 2 enables fluid to flow from the sewage inlet side to the sewage outlet side and prevents fluid backflow. In other words, the odor-blocking component 2 enables fluid (such as urine, flushing water, or odor) to flow in one direction, forming a second odor barrier while preventing fluid backflow.
[0043] The odor-proof structure provided in this embodiment, under the dual action of the odor-blocking component 2 and the water trap 113, can effectively prevent the odor from the sewer from rising, has a good odor-proof effect, greatly reduces the volatilization of odor, creates a good sanitary environment, and improves the user experience.
[0044] like Figure 2 and Figure 3 As shown, the odor-blocking assembly 2 includes an odor-blocking filter element 21. The odor-blocking filter element 21 includes a filter element body 211, a baffle 212, and a reset structure. The filter element body 211 is vertically continuous and has a top opening 2111 and a bottom opening 2112. The baffle 212 is rotatably connected to the filter element body 211, and the reset structure is disposed between the filter element body 211 and the baffle 212. The baffle 212 can open the bottom opening 2112 of the filter element body 211 under the action of gravity of the fluid, and the baffle 212 can also be reset by the action of the reset structure to seal the bottom opening 2112 of the filter element body 211.
[0045] In other words, when fluid flows down into the toilet bowl body 100, the baffle 212 opens the bottom opening 2112 of the filter body 211 to allow the fluid to flow to the water seal bend 11 and the drain pipe 12. When there is no fluid in the toilet bowl body 100, the baffle 212 returns to its original position, preventing odors from rising from the pipe.
[0046] Specifically, in this embodiment, such as Figure 3 As shown, the reset structure includes a first magnetic element 213 and a second magnetic element 214. One of the two magnetic elements 213 and 214 is disposed on the filter element body 211, and the other is disposed on the baffle 212. The first magnetic element 213 and the second magnetic element 214 reset the baffle 212 through the principle of attraction between opposite magnetic poles or repulsion between like magnetic poles. Utilizing the magnetic properties of the magnetic elements themselves to form the reset structure reduces the likelihood of fatigue and failure to reset, thus helping to extend the service life of the odor-blocking filter element 21.
[0047] Of course, in other embodiments, the odor-blocking filter element 21 can also be a spring structure odor-blocking filter element, a gravity structure odor-blocking filter element, or a silicone structure odor-blocking filter element, etc., as long as it can play the role of allowing the fluid to flow in one direction and preventing the odor from flowing back. There is no limitation here.
[0048] More specifically, the odor-blocking filter element 21 also includes a sealing gasket 215, which is disposed on the side of the baffle 212 facing the filter element body 211. The sealing gasket 215 can abut against the periphery of the bottom opening 2112 of the filter element body 211 when the baffle 212 seals the bottom opening 2112, thereby improving the sealing performance between the baffle 212 and the filter element body 211, and further enhancing the odor-blocking effect of the odor-blocking filter element 21. For example, the sealing gasket 215 is made of silicone.
[0049] More specifically, the odor-blocking filter element 21 also includes a sealing ring 216, which is sleeved on the filter element body 211 and sandwiched between the filter element body 211 and the inner wall of the pipe below the drain outlet 101 of the toilet body 100. The sealing ring 216 can improve the sealing between the filter element body 211 and the pipe below the drain outlet 101 of the toilet body 100, preventing odors from escaping from the gap between the filter element body 211 and the pipe. For example, the sealing ring 216 is a silicone sealing ring.
[0050] Optionally, continue to refer to Figure 1 and Figure 2 The odor-blocking component 2 also includes a drain plug 22. The drain plug 22 has multiple water passage holes 221 and is detachably installed on the drain outlet 101 of the toilet body 100. Odor-blocking filter elements 21 are spaced below the drain plug 22. The drain plug 22 can perform simple filtration of large particulate impurities in the fluid before it enters the odor-blocking filter elements 21. This design helps prevent impurities from clogging the odor-blocking filter elements 21, thereby ensuring the service life and odor-blocking effect of the odor-blocking filter elements 21.
[0051] Specifically, an installation step 102 is provided circumferentially on the inner wall of the pipe below the drain outlet 101 of the toilet body 100, and the periphery of the top opening 2111 of the filter element body 211 extends outward to form an installation part 2113. The installation part 2113 can overlap the installation step 102 to achieve a detachable connection between the filter element body 211 and the pipe below the drain outlet 101 of the toilet body 100.
[0052] In this embodiment, the height of the odor-blocking filter element 21 is 30-40mm. The odor-blocking filter element 21 is installed 10-15mm below the drain plug 22 and 100-130mm above the water seal inside the pipe. The installation position of the odor-blocking filter element 21 has a single-sided slurry structure so that the sealing ring 216 of the odor-blocking filter element 21 can be secured to the inner wall of the pipe, preventing the odor-blocking filter element 21 from popping out and thus losing its odor-blocking function.
[0053] In other embodiments, the drain plug 22 is disposed at the top opening 2111 of the filter element body 211, and the drain plug 22 and the odor-blocking filter element 21 are an integral structure. This arrangement can improve the overall integrity of the odor-blocking assembly 2 and facilitate installation and subsequent disassembly and maintenance.
[0054] The odor-proof principle of the urinal's odor-proof structure provided in this embodiment is as follows (using urine as an example):
[0055] During use, urine is discharged onto the pot surface 103 and drain plug 22 of the toilet body 100. It flows quickly through the drain plug 22 to the odor-blocking filter element 21, and then through the baffle 212 to the water seal bend 11 and the sewage pipe 12, reducing the time that urine exists in the air and preventing the odor in the urine from evaporating.
[0056] Meanwhile, the water in the urinal water seal bend 11 is diluted sewage. The water in the water seal bend 11 will prevent the odor in the sewer from rising. However, the sewage will evaporate and produce odor. The baffle 212 of the odor-blocking filter 21 can prevent the odor from evaporating into the air.
[0057] When the pipe is unused for a long time, the water level in the water seal bend 11 will drop to the bottom of the pipe. At this time, the baffle 212 of the odor-blocking filter element 21 can prevent the odor in the sewer from rising.
[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
