[0036] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0037] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0040] As Figures 1 to 7 shown, the present utility model provides a flushing assembly, which includes a water delivery pipe 1 and a plugging assembly 2. The water delivery pipe 1 is used for delivering water; the plugging assembly 2 is arranged on the water delivery pipe 1. An exhaust port 3 is arranged on the water delivery pipe 1 or the plugging assembly 2. The water delivery pipe 1 is communicated with the outside through the exhaust port 3. The plugging assembly 2 further includes a plugging member, and the plugging member has a first state and a second state that can be switched with each other. When the plugging member is in the first state, the plugging member plugs the exhaust port 3; when the plugging member is in the second state, the plugging member opens the exhaust port 3; the flowing water in the water delivery pipe 1 can act on the plugging member to make it tend to maintain the first state, and after the flowing water disengages from the plugging member, the plugging member has a tendency to maintain the second state.

[0041] By arranging a plugging assembly 2 on the water delivery pipe 1, it is possible to control the plugging member to plug the exhaust port 3 during the water delivery process of the water delivery pipe 1, so that water can be normally delivered through the water delivery pipe 1; when the water in the water delivery pipe 1 separates from the plugging member, the exhaust port 3 is opened, and the water delivery pipe 1 is communicated with the outside through the exhaust port 3. If there is tail gas in the water delivery pipe 1, it can be discharged through the exhaust port 3.

[0042] Thus, when the flushing assembly is arranged on the toilet and the water delivery pipe 1 is connected to the water tank 5 and the pot surface, after the water in the water tank 5 normally and smoothly enters the pot surface through the water delivery pipe 1 for flushing, the tail gas in the water delivery pipe can be discharged, preventing it from entering the pot surface and generating a "gurgling" noise, thus ensuring the user experience.

[0043] As Figures 1 to 3 shown, in some embodiments, the plugging assembly 2 includes a connecting pipe 21 and a plug body 22, and the water delivery pipe 1 includes a first pipe 11 and a second pipe 12. The connecting pipe 21 is arranged between the first pipe 11 and the second pipe 12. That is to say, one of the first pipe 11 and the second pipe 12 is connected to the pot surface and the connecting pipe 21, and the other is connected to the water tank 5 and the connecting pipe 21. The first pipe 11 and the second pipe 12 are transferred through the connecting pipe 21. For the convenience of description, hereinafter, it is assumed that the first pipe 11 is connected to the pot surface and the second pipe 12 is connected to the water tank 5 for explanation. The exhaust port 3 is arranged on the connecting pipe 21, and the plug body 22 is connected inside the connecting pipe 21, and the connection position between the two is located upstream of the exhaust port 3. It should be noted that the upstream and downstream of the exhaust port 3 are based on the water delivery direction of the water delivery pipe 1. The plug body 22 can move relative to the connecting pipe 21. When the water delivery pipe 1 delivers water, the exhaust port 3 is plugged. Exemplarily, the plug body 22 rotates relative to the connecting pipe 21. When the flowing water acts on the plug body 22, the plug body 22 rotates relative to the connecting pipe 21, pressing the plug body 22 against the connecting pipe 21 to plug the exhaust port 3. Subsequently, after the flowing water passes, the plug body 22 loses the abutment of the flowing water, and the external atmospheric pressure is greater than the air pressure inside the water delivery pipe 1. The plug body 22 opens the exhaust port 3 to communicate with the outside, and the tail gas in the water delivery pipe 1 can be discharged. Exemplarily, to achieve the rotation of the plug body 22 relative to the connecting pipe 21, one way is to connect the plug body 22 to the connecting pipe 21 by means of a hinge shaft; another way is to rotate through the elastic deformation of the plug body 22 itself. In the current embodiment, for the sake of simplifying the structure, the plug body 22 realizes the above rotation by means of elastic deformation.

[0044] As Figure 2 and Figure 3As shown, in order to facilitate the connection of the plug body 22 to the connecting pipe 21, in some embodiments, the plugging assembly 2 further includes a plug ring 23. The plug ring 23 is sleeved on the connecting pipe 21, and the plug body 22 is arranged on the plug ring 23, so as to fix the plug body 22 by means of the plug ring 23. Exemplarily, the plug ring 23 can also be made of an elastic material. The plug ring 23 and the plug body 22 can be made of elastic materials such as rubber or silica gel, but are not limited thereto; the two are integrally formed, which is convenient for manufacturing. In addition, the plug ring 23 made of an elastic material can also be easily sleeved on the connecting pipes 21 of different sizes, and the plug body 22 made of an elastic material can also make the plug body 22 lose the resistance of flowing water, and has a tendency to return to the second state more stably, so that it can quickly disengage from the exhaust port 3.

[0045] More specifically, the port of the connecting pipe 21 located upstream of the exhaust port 3 is provided with an insertion groove 212 along the axial direction of the connecting pipe 21. A protruding insertion block 211 is arranged at the bottom of the insertion groove 212. The plug body 22 is connected to the inner ring side of the plug ring 23. An insertion port 24 is arranged at the connection between the plug body 22 and the plug ring 23. When the plug ring 23 is sleeved on the connecting pipe 21, the insertion port 24 can be inserted into the above-mentioned insertion block 211, so as to fix the plug ring 23 and the plug body 22 on the connecting pipe 21. Further, in order to prevent the plug ring 23 from moving on the connecting pipe 21, spaced limiting ribs 213 are arranged on the outer wall of the connecting pipe 21, and the plug ring 23 is clamped between the two spaced limiting ribs 213 to limit and stabilize it.

[0046] Further, a protrusion 25 is arranged on the plug body 22. The shape of the protrusion 25 matches the shape of the exhaust port 3. Thus, when the plug body 22 plugs the exhaust port 3, the protrusion 25 is embedded into the exhaust port 3, so as to ensure the tightness of the plugging to a certain extent.

[0047] In some embodiments, the connecting pipe 21 can rotate relative to the first pipe 11 and the second pipe 12, so as to adjust the position of the exhaust port 3 by rotating the connecting pipe 21; Exemplarily, the first pipe 11, the second pipe 12 and the connecting pipe 21 are all connected by insertion, and the above-mentioned insertion connection method can also more conveniently adjust the angle of the connecting pipe 21. It can be understood that the form of the connecting pipe 21 is not specifically limited. It can be a bent pipe or a straight pipe, and can be selected according to different installation environments.

[0048] Such as Figure 4 and Figure 5As shown, in some alternative embodiments, the water delivery pipe 1 also includes a first pipe 11 and a second pipe 12, and the plugging assembly 2 includes a vacuum breaker 26. The vacuum breaker 26 is a prior art, and its structure mainly includes a housing 265 and a movable plug 263. An inlet 261 and an outlet 262 are provided at the bottom of the housing 265. The movable plug 263 is slidably installed in the housing 265. A vent 264 is provided at the top of the housing 265 corresponding to the position of the movable plug 263. When using the vacuum breaker 26, the plugging member is the above-mentioned movable plug 263, and the exhaust port 3 is the above-mentioned vent 264. The first pipe 11 can be connected to the outlet 262 of the vacuum breaker 26, and the second pipe 12 can be connected to the inlet 261 of the vacuum breaker 26. Thus, during the movement of the movable plug 263, the vent 264 can be opened or closed. That is to say, when the flowing water enters the vacuum breaker 26, the movable plug 263 is pushed by the flowing water to move and block the vent 264, so that the flowing water can flow out from the outlet 262. When the flowing water enters the outlet 262, the movable plug 263 loses support and returns to its original position, and then the vent 264 can be opened to communicate with the outside to discharge the tail gas.

[0049] As Figure 6 and Figure 7 shown, in some other alternative embodiments, the plugging assembly 2 includes an air outlet valve 27, and the above-mentioned exhaust port 3 is provided on the water delivery pipe 1. The air outlet valve 27 is arranged in the exhaust port 3. When the air outlet valve 27 is adopted, the plugging member is the valve core 274 of the air outlet valve 27, so as to open or close the exhaust port 3 through the movement of the valve core 274. Specifically, the air outlet valve 27 includes a valve seat 271, a sealing ring 272, a stop portion 273 and a valve core 274. The valve seat 271 is hermetically arranged in the exhaust port 3 through a sealing ring arranged outside the valve seat 271. The valve seat 271 has a through cavity. The stop portion 273 and the sealing ring 272 are arranged at intervals in the through cavity of the valve seat 271. The sealing ring 272 is arranged around the inner cavity wall of the through cavity, and the stop portion 273 is arranged upstream of the sealing ring 272. The stop portion 273 has a flow-through hole 275, which can enable the air flow to pass through the stop portion 273 and be discharged from the air outlet valve 27. It should be noted here that the upstream and downstream of the sealing ring 272 are based on the direction of the air flow discharged from the air outlet valve 27. The above-mentioned valve core 274 is also arranged in the through cavity. The valve core 274 moves between the stop portion 273 and the sealing ring 272 to limit the movement range of the valve core 274. Thus, through the above structure, the exhaust port 3 can be blocked when the valve core 274 abuts against the sealing ring 272, and the exhaust port 3 can be opened when the valve core 274 is separated from the sealing ring 272.

[0050] As Figure 7As shown, more specifically, the blocking portion is provided with a perforation 276, and the valve core 274 is umbrella-shaped. The end of the umbrella rod is inserted into the perforation 276, with the top of the umbrella facing the sealing ring 272. The maximum diameter of the top of the umbrella is greater than the inner diameter of the sealing ring 272 and less than the inner diameter of the through cavity. When the flowing water acts on the valve core 274, it pushes the valve core 274 away from the stop portion 273 and moves towards the sealing ring 272. The insertion of the end of the umbrella rod into the perforation 276 can keep the movement of the valve core 274 stable. When the valve core 274 contacts the sealing ring 272, the two are abutted and closed to prevent the flowing water from passing through. When the valve core 274 loses the abutment of the flowing water, the atmospheric pressure outside is greater than the air pressure in the water delivery pipe 1, so that the valve core 274 is separated from the sealing ring 272. Thus, the outside communicates with the water delivery pipe 1 through the gap between the valve core 274 and the inner wall of the through cavity and the overflow hole 275 on the stop portion 273, and the exhaust gas can be discharged. In the current embodiment, in order to enable the valve core 274 to quickly return to its original position when it loses the abutment of the flowing water, the exhaust hole in this embodiment is a vertical exhaust hole, and the valve core 274 can also return to its original position by its own gravity. Exemplarily, the sealing ring 272 is an annular sealing ring.

[0051] As Figure 1 shown, since during the exhaust process, the exhaust gas will carry some water and overflow from the water delivery pipe 1. In order to reduce the impact of the overflow water on other components in the toilet, in some embodiments, the flushing assembly further includes an overflow pipe 4. One end of the overflow pipe 4 is connected to the exhaust port 3, and the other end of the overflow pipe 4 is connected to the water tank 5, so as to divert the overflow water into the water tank 5 for concentration.

[0052] The present utility model also provides a toilet, which includes a water tank 5, a pot surface, and the above-mentioned flushing assembly. The water delivery pipe 1 is connected to the water tank 5 and the pot surface, so that after the water tank 5 delivers water to the pot surface, the exhaust gas in the water delivery pipe 1 can be discharged, avoiding the "gurgling" noise and ensuring the user experience.

[0053] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly explaining the present utility model, and are not intended to limit the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
