Description

Technical Field

[0001] The present application relates to the field of sanitary ware, and more particularly, to a toilet and a one-way valve for a jet hole of a toilet. Background Art

[0002] Currently, the flushing structure of a toilet usually forms a three-way structure by connecting a drain pipe to a water guide ring and a jet pipe. Since the drain pipe is interconnected with both the water guide ring and the jet pipe, during flushing, the air in the jet pipe escapes from the washing holes of the water guide ring, etc., resulting in a loss of flushing kinetic energy and making it difficult to achieve efficient water conservation.

[0003] In the prior art, to solve the above problems, the drain pipe is directly and separately connected to the jet pipe, and a jet chamber connected to the jet pipe is provided below the water storage surface. The jet holes are opened in the jet chamber located below the water storage surface, and the water guide ring is connected to the jet chamber located below the water storage surface to prevent the loss of flushing kinetic energy. However, the inventor found that in this design, the basin is easily contaminated by dirt during use, resulting in an unqualified dilution rate and a risk of cross-infection, affecting the use safety. Summary of the Invention

[0004] An object of the present application is to provide a toilet and a one-way valve for a jet hole of a toilet, which have better flushing kinetic energy and can effectively avoid the basin being contaminated by dirt during use.

[0005] The embodiments of the present application are implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a toilet, including a basin, a water guide ring, a washing pipe, a drain pipe, and a water tank. The toilet has a jet chamber located below the water storage surface of the basin. The drain pipe is connected between the drain outlet of the water tank and the jet chamber, the washing pipe is connected between the water guide ring and the jet chamber, the jet chamber is provided with jet holes communicating with the inner cavity of the basin, and a one-way valve is connected to the jet holes. The one-way valve is configured such that water can flow unidirectionally into the basin.

[0007] The inventor's research found that in the design of directly and separately connecting the drain pipe to the jet pipe and providing a jet chamber connected to the jet pipe below the water storage surface, during use, the dirt in the inner cavity of the basin easily enters the jet chamber through the jet holes. The dirt entering the jet chamber will be diluted into the washing pipe and then enter the water guide ring, causing the basin to be contaminated by dirt when the water guide ring supplies water to wash the inner wall of the basin, thus resulting in the problem of unqualified dilution rate.

[0008] In the above technical solution, the injection holes are opened in the injection chamber located below the water storage surface, and the water guide ring is communicated with the injection chamber located below the water storage surface through a washing pipe. During flushing, since the injection chamber is located below the water storage surface, the water supply from the drain pipe first sprays water into the inner cavity of the basin from the one-way valve at the injection hole, and the remaining water supply enters the water guide ring through the washing pipe by way of overflow for flushing the inner wall of the basin. Since the injection chamber is directly communicated with the drain outlet of the water tank through the drain pipe, and the washing pipe supplies water to the water guide ring by way of overflow, it can effectively avoid the loss of flushing kinetic energy caused by the escape of air in the pipeline, so that the water sprayed from the one-way valve at the injection hole has better flushing kinetic energy. Arranging the injection chamber at the water outlet end of the drain pipe facilitates the installation of the one-way valve; the setting of the one-way valve enables the water flow to flow into the basin unidirectionally, and the water in the water seal in the basin cannot flow into the injection chamber, which can avoid the backflow of the dirt in the inner cavity of the basin into the injection chamber and dilution into the washing pipe and then into the water guide ring when the drain pipe stops draining, and can effectively avoid the contamination of the basin by dirt during use.

[0009] In some possible embodiments, the one-way valve includes a valve body and a connecting portion, and the connecting portion is used for detachably connecting with the injection hole, and the valve body is configured to enable the water flow to flow into the basin unidirectionally.

[0010] In the above technical solution, the one-way valve is detachably connected with the injection hole through the connecting portion, which facilitates the installation of the one-way valve during production and also facilitates the replacement of the one-way valve as needed during use.

[0011] In some possible embodiments, the valve body includes a first housing, a first seal and a restoring member. The first housing is connected to the connecting portion, the first housing has a first water inlet communicated with the injection hole, the first seal has a first position for sealing the first water inlet and a second position for opening the first water inlet, and the restoring member is connected between the first housing and the first seal. The restoring member is configured to drive the first seal to be in the first position and allow the first seal to move from the first position to the second position under the impact of the water flow flowing into the basin.

[0012] In the above technical solution, the valve body is provided with a restoring member for driving the first seal to be in the first position. During flushing, the restoring force generated by the restoring member on the first seal has a buffering effect on the movement of the first seal, so that the first seal can move smoothly to the second position under the impact of the water flow; after flushing is completed, the restoring force generated by the restoring member on the first seal enables the first seal to automatically return to the first position, so that the reliability of the opening and closing of the one-way valve is good.

[0013] In some possible embodiments, the first seal is slidably sleeved within the first housing. The restoring member includes a guiding member and an elastic telescopic member. The first end of the guiding member is connected to the first seal, the second end of the guiding member is slidably connected to the first housing, and the elastic telescopic member abuts between the first seal and the first housing. Under the impact of the water flow flowing into the basin body, the first seal can slide from the first position to the second position.

[0014] In the above technical solution, the elastic telescopic member is provided as the restoring member, so that the first seal moves between the first position and the second position in a sliding manner. Since the elastic telescopic member has good stability during the telescopic process and the sliding movement mode also has good stability, the first seal can stably move between the first position and the second position. During flushing, the first seal slides from the first position to the second position by compressing the elastic telescopic member. The water flow in the jet chamber can easily wash open the first seal, and the sensitivity of the valve body to open the water flow channel under the impact of the water flow flowing into the basin body is high. The elastic telescopic member also has a high number of impact resistance deformations, so that the valve body can have a long service life.

[0015] In some possible embodiments, the first water inlet is opened on the end face of the first housing away from the connecting portion. When the first seal is in the second position, there is a water flow gap for water flow to pass through between the first seal and the first housing.

[0016] In the above technical solution, the first water inlet is opened on the end face of the first housing, and the water flow gap between the first seal and the first housing when the first seal is in the second position is used for water flow to pass through. The water flow gap can reduce the sliding friction between the first seal and the first housing when the first seal moves between the first position and the second position, making it easier for the water flow in the jet chamber to wash open the first seal, and the sensitivity of the valve body to open the water flow channel under the impact of the water flow flowing into the basin body is higher.

[0017] In some possible embodiments, the valve body is configured to be able to extend through the jet hole into the jet chamber. The connecting portion includes a buckle member, an external threaded pipe, and a first sealing assembly. The external threaded pipe is communicated with the valve body. The buckle member is arranged at one end of the external threaded pipe close to the valve body. The buckle member is configured to be able to pass through the jet hole and abut against the inner wall of the jet chamber. The first sealing assembly is used for detachable connection with the external threaded pipe, and when the buckle member abuts against the inner wall of the jet chamber, it abuts against the outer wall of the jet chamber and closes the gap between the inner wall of the jet hole and the outer wall of the external threaded pipe.

[0018] In the above technical solution, the connecting part passes through the injection hole by a buckle and abuts against the inner wall of the injection chamber, and then through the detachable connection of the first sealing assembly with the external threaded pipe to abut against the outer wall of the injection chamber and seal the gap between the inner wall of the injection hole and the outer wall of the external threaded pipe. The connection between the one-way valve and the injection hole is convenient and has good sealing performance. The valve body is configured to be able to extend into the injection chamber through the injection hole, so that the valve body works in the injection chamber, which can effectively protect the valve body.

[0019] In some possible implementation schemes, the hole wall of the injection hole is recessed axially with a buckle chute for sliding cooperation with the buckle part, so that the buckle part can pass through the injection hole through the buckle chute.

[0020] In the above technical solution, the buckle part of the connecting part can conveniently pass through the injection hole through the buckle chute, making the installation and disassembly of the one-way valve in the injection hole more convenient.

[0021] In some possible implementation schemes, the restoring part includes a mounting shaft and an elastic torsion part arranged on the mounting shaft. The first seal is a plate body. The first housing and the first seal are rotatably connected through the mounting shaft. The elastic torsion part includes opposite first torsion arms and second torsion arms. The first torsion arm is connected to the first housing, and the second torsion arm is connected to the first seal. Under the impact of the water flow flowing into the basin, the first seal can rotate from the first position to the second position.

[0022] In the above technical solution, the elastic torsion part is set as the restoring part, so that the first seal moves between the first position and the second position by rotating. When the first seal is in the second position, the water inlet can reach a larger opening degree, so that the water flow flowing into the inner cavity of the basin can better meet the water spraying requirements for the sewage outlet of the basin.

[0023] In some possible implementation schemes, the valve body includes a second housing, a second sealing baffle and a connecting shaft. The second housing is connected to the connecting part. The second housing has a second water inlet communicating with the injection hole. The second sealing baffle has a third position for sealing the second water inlet and a fourth position for opening the second water inlet. The connecting shaft is connected between the top of the second housing and the second sealing baffle. The average density of the second sealing baffle is greater than the density of water. The second sealing baffle is configured to be able to press on the upper part of the second water inlet when in the third position and can rotate from the third position to the fourth position under the impact of the water flow flowing into the basin.

[0024] In the above technical solution, the second sealing baffle moves between the third position and the fourth position by rotating. When the second sealing baffle is in the fourth position, the water inlet can achieve a relatively large opening degree, so that the water flow flowing into the inner cavity of the basin can better meet the water spraying requirements for the sewage outlet of the basin. The average density of the second sealing baffle is greater than the density of water. When the second sealing baffle is in the third position, it presses on the second water inlet by its own gravity to close the second water inlet, and the structure of the valve body is simple. At the same time, the second sealing baffle is restored by gravity without being limited by the number of restoration times, so that the valve body can have a long service life.

[0025] In some possible implementation solutions, the valve body is located in the inner cavity of the basin. The connecting part includes a connecting sleeve and a second sealing gasket. The connecting sleeve is communicated with the valve body, and the second sealing gasket is sleeved between the outer wall of the connecting sleeve and the inner wall of the spraying hole.

[0026] In the above technical solution, the connecting part is sleeved in the spraying hole through the connecting sleeve and is sealed by the second sealing gasket. The connection between the one-way valve and the spraying hole is convenient and has good sealing performance.

[0027] In some possible implementation solutions, the water tank of the toilet is provided with an overflow communication channel. The water inlet valve of the water tank is provided with a make-up water pipe. The overflow communication channel is communicated between the water guide ring and the make-up water pipe of the water tank. An overflow hole communicated with the inner cavity of the water tank is also opened at the upper end of the overflow communication channel.

[0028] In the above technical solution, the water guide ring is communicated with the make-up water pipe of the water inlet valve of the water tank through the overflow communication channel. When the water tank fills water through the water inlet valve, the water flow can flow into the water guide ring through the overflow communication channel and then replenish the inner cavity of the basin through the water guide ring and the washing pipe, so that the water tank can replenish the inner cavity of the basin when filling water, which is convenient for the restoration of the water seal of the basin; the overflow hole is communicated between the overflow communication channel and the inner cavity of the water tank, and also plays a role in preventing the overflow of the toilet.

[0029] In a second aspect, an embodiment of the present application provides a toilet, including a basin, a water guide ring, a washing pipe, a drain pipe and a water tank. The toilet has a spraying chamber located below the water storage surface of the basin. The drain pipe is communicated between the drain port of the water tank and the spraying chamber. The washing pipe is communicated between the water guide ring and the spraying chamber. The spraying chamber is provided with a spraying hole communicated with the inner cavity of the basin. The spraying hole is axially recessed with a snap groove for sliding cooperation with the snap member.

[0030] In the above technical solution, the injection holes are opened in the injection chamber located below the water storage surface, and the water guide ring is communicated with the injection chamber located below the water storage surface through a washing pipe. Since the injection chamber is directly communicated with the drain outlet of the water tank through a drain pipe, and the washing pipe supplies water to the water guide ring by means of overflow, it can effectively avoid the loss of washing kinetic energy caused by the escape of air in the pipeline, so that the injection holes have better washing kinetic energy. The injection chamber is arranged at the water outlet end of the drain pipe, which is convenient for opening the injection holes. The injection holes are axially recessed with snap grooves for sliding cooperation with the snap members, which is convenient for the installation and replacement of the one-way valve with snap members in the injection holes.

[0031] In a third aspect, an embodiment of the present application provides a one-way valve for an injection hole of a toilet. The toilet has an injection chamber located below the water storage surface of the basin body. The injection chamber is provided with an injection hole communicated with the inner cavity of the basin body. The one-way valve includes a valve body and a connecting portion. The valve body is configured to be able to pass through the injection hole and extend into the injection chamber so that water can flow unidirectionally into the basin body of the toilet; the connecting portion includes a snap member, an external threaded pipe, and a first sealing assembly. The external threaded pipe is communicated with the valve body. The snap member is arranged at one end of the external threaded pipe close to the valve body. The snap member is configured to be able to pass through the injection hole and abut against the inner wall of the injection chamber; the first sealing assembly is used for detachably connecting with the external threaded pipe, and when the snap member abuts against the inner wall of the injection chamber, it abuts against the outer wall of the injection chamber and closes the gap between the inner wall of the injection hole and the outer wall of the external threaded pipe.

[0032] In the above technical solution, the connecting portion of the one-way valve passes through the injection hole with a snap and abuts against the inner wall of the injection chamber, and then the first sealing assembly is detachably connected with the external threaded pipe to abut against the outer wall of the injection chamber and close the gap between the inner wall of the injection hole and the outer wall of the external threaded pipe. The connection between the one-way valve and the injection hole is convenient and has good sealing performance, and it can be well installed and used in the injection hole of the toilet. The valve body is configured to be able to pass through the injection hole and extend into the injection chamber, so that the valve body works in the injection chamber, which can effectively protect the valve body.

[0033] In some possible implementation schemes, the valve body includes a first housing, a first sealing member, and a return member. The first housing is connected to the connecting portion. The end surface of the first housing far from the connecting portion has a first water inlet for communicating with the injection hole. The first sealing member has a first position for sealing the first water inlet and a second position for opening the first water inlet. When the first sealing member is in the second position, there is a flowing water gap for water flow between the first sealing member and the first housing. The return member includes a guiding member and an elastic telescopic member. The first end of the guiding member is connected to the first sealing member, the second end of the guiding member is slidably connected to the first housing, and the elastic telescopic member abuts between the first sealing member and the first housing. Under the impact of the water flow flowing into the basin body, the first sealing member can slide from the first position to the second position.

[0034] In the above technical solution, an elastic telescopic member is provided as a restoring member, so that the first seal moves between the first position and the second position in a sliding manner, enabling the first seal to move stably between the first position and the second position. During flushing, the first seal slides from the first position to the second position by compressing the elastic telescopic member; the first water inlet is opened on the end face of the first housing, and the flowing water gap between the first seal and the first housing when the first seal is in the second position prevents sliding friction between the first seal and the first housing, and the water flow in the injection chamber can easily flush open the first seal, and the valve body has high sensitivity in opening the water flow channel under the impact of the water flow flowing into the basin body.

[0035] In a fourth aspect, an embodiment of the present application provides a one-way valve for a jet hole of a toilet. The toilet has an injection chamber located below the water storage surface of the basin body, and the injection chamber is provided with a jet hole communicating with the inner cavity of the basin body. The one-way valve includes a valve body and a connecting portion. The valve body is configured to enable water to flow unidirectionally into the basin body of the toilet. The connecting portion includes a connecting sleeve and a second sealing gasket. The connecting sleeve communicates with the valve body, and the second sealing gasket is used to be sleeved between the outer wall of the connecting sleeve and the inner wall of the jet hole.

[0036] In the above technical solution, the connecting portion of the one-way valve is sleeved in the jet hole through the connecting sleeve and is sealed by the second sealing gasket. The connection between the one-way valve and the jet hole is convenient and has good sealing performance, and it can be well installed and used in the jet hole of the toilet.

[0037] In some possible implementation schemes, the valve body includes a second housing, a second sealing baffle and a connecting shaft. The second housing is connected to the connecting portion. The second housing has a second water inlet communicating with the jet hole. The second sealing baffle has a third position for sealing the second water inlet and a fourth position for opening the second water inlet.

The average density of the second sealing baffle is greater than the density of water. When the second sealing baffle is in the third position, it uses its own gravity to press on the upper part of the second water inlet to achieve the closure of the second water inlet, and the structure of the valve body is simple.

[0058] Embodiment

[0059] Please refer to Figures 1-2 , an embodiment of the present application provides a toilet 100, including a basin body 120, a water guide ring 130, a flushing pipe 140, a drain pipe 150, and a water tank 160. The toilet 100 has a jet chamber 110 located below the water storage surface of the basin body 120, and the drain pipe 150 communicates the drain port 161 of the water tank 160 with the jet chamber 110.

[0060] The jet chamber 110 is provided with a jet hole 111 communicating with the inner cavity of the basin body 120. The jet hole 111 is connected with a one-way valve 170, and the one-way valve 170 is configured to enable the water flow to flow unidirectionally into the basin body 120. The jet hole 111 is used to spray the water flow in the jet chamber 110 unidirectionally into the inner cavity of the basin body 120. Further, the jet hole 111 is disposed opposite to the sewage outlet 121 of the basin body 120, and can spray the dirt below the water storage surface of the basin body 120 towards the sewage outlet 121 of the basin body 120 to promote the faster discharge of the dirt from the inner cavity of the basin body 120.

[0061] The washing pipe 140 is connected between the water guiding ring 130 and the spraying chamber 110. The bottom end of the washing pipe 140 is connected to the spraying chamber 110, and the top end of the washing pipe 140 is connected to the water guiding ring 130. The water guiding ring 130 is provided with a plurality of washing holes 131 communicating with the inner cavity of the water guiding ring 130 along the circumferential direction. The washing holes 131 are used to spray the water in the water guiding ring 130 into the inner cavity of the basin body 120 and wash the inner wall of the basin body 120.

[0062] In the embodiment of the present application, the spraying holes 111 are opened in the spraying chamber 110 located below the water storage surface, and the water guiding ring 130 is connected to the spraying chamber 110 located below the water storage surface through the washing pipe 140. During flushing, since the spraying chamber 110 is located below the water storage surface, the water supply of the drain pipe 150 first sprays water into the inner cavity of the basin body 120 from the one-way valve 170 at the spraying holes 111, and the remaining water supply enters the water guiding ring 130 through the washing pipe 140 by means of overflow for flushing the inner wall of the basin body 120. Since the spraying chamber 110 is directly connected to the drain port 161 of the water tank 160 through the drain pipe 150, and the washing pipe 140 supplies water to the water guiding ring 130 by means of overflow, it can effectively avoid the loss of flushing kinetic energy caused by the escape of air in the pipeline, so that the water sprayed by the one-way valve 170 at the spraying holes 111 has better flushing kinetic energy. Arranging the spraying chamber 110 at the water outlet end of the drain pipe 150 facilitates the installation of the one-way valve 170; the setting of the one-way valve 170 enables the water flow to flow into the basin body 120 unidirectionally. When the drainage stops, it can prevent the dirt in the inner cavity of the basin body 120 from flowing back into the spraying chamber 110 and diluting into the washing pipe 140, and can effectively prevent the basin body 120 from being contaminated by dirt during use.

[0063] It can be understood that in the embodiment of the present application, the drainage method of the drain port 161 of the water tank 160 to the drain pipe 150 is not limited. It can be drained by setting a drain valve 162 with an overflow pipe at the drain port 161, or a drain valve 162 without an overflow pipe can be directly set at the drain port 161. Please refer to Figure 3 , for example, the drain port 161 of the water tank 160 is directly installed with a drain valve 162 without an overflow pipe. When the drain valve 162 drains water, no air enters the drain pipe 150 from the drain port 161, so that the drain pipe 150 can always maintain a state of being filled with water during use, and can realize the full-pressure flushing of the water storage potential energy of the water tank 160, making the water sprayed from the spraying holes 111 have a better spraying effect.

[0064] In the embodiments of the application, the connection manner between the washing pipe 140 and the water guide ring 130 is not limited. Exemplarily, a liquid outlet chamber 132 communicating with the water guide ring 130 is provided at the bottom of the water guide ring 130. The bottom of the liquid outlet chamber 132 is connected and communicated with the top end of the washing pipe 140. The top end of the washing pipe 140 is communicated with the water guide ring 130 through the liquid outlet chamber 132. The arrangement of the liquid outlet chamber 132 facilitates the molding of the washing pipe 140. It can be understood that in the embodiments of the present application, the top end of the washing pipe 140 can also be directly connected and communicated with the bottom of the water guide ring 130.

[0065] In some possible implementation manners, an overflow communication channel 165 is provided in the water tank 160 of the toilet 100. The water tank 160 is provided with a water inlet pipe 163 and a water inlet valve 164 connected to the water inlet pipe 163 to realize the water inlet and water stop of the water tank 160. The water inlet valve 164 is connected with a make-up water pipe 166. The overflow communication channel 165 is communicated between the water guide ring 130 and the make-up water pipe 166 of the water inlet valve 164 of the water tank 160. When the water tank 160 is filled with water through the water inlet valve 164, a part of the water flow flows into the inner cavity of the water tank 160 through the water inlet valve 164; another part of the water flow flows into the make-up water pipe 166 and can flow into the water guide ring 130 through the overflow communication channel 165, and then the inner cavity of the basin body 120 is filled with water through the water guide ring 130 and the washing pipe 140, so that the inner cavity of the basin body 120 can be filled with water when the water tank 160 is filled with water, which is convenient for the restoration of the water seal of the basin body 120.

[0066] An overflow hole 167 communicating with the inner cavity of the water tank 160 is further opened on the upper side wall of the overflow communication channel 165, which is used to communicate the overflow communication channel 165 and the inner cavity of the water tank 160, so that when the liquid level in the water tank 160 exceeds the safety water level, overflow occurs through the overflow hole 167.

[0067] It can be understood that in the embodiments of the present application, the positional relationship between the make-up water pipe 166 and the overflow hole 167 can be set as required. In an exemplary implementation manner, the inner cavity of the overflow hole 167 is larger than the outer wall of the make-up water pipe 166. The overflow hole 167 is, for example, set as a long strip hole. The make-up water pipe 166 is installed in the overflow hole 167, and there is a gap between the make-up water pipe 166 and the overflow hole 167, so that the overflow hole 167 has an overflow function, so that when the water level in the water tank 160 exceeds the overflow hole 167, the water flow can overflow through the gap between the overflow hole 167 and the make-up water pipe 166. In another exemplary implementation manner, an installation opening (not shown in the figure) is further opened on the upper side wall of the overflow communication channel 165, and the make-up water pipe 166 is in sealing fit with the installation opening to realize the installation of the make-up water pipe 166 in the overflow communication channel 165, so that when the water level in the water tank 160 exceeds the overflow hole 167, the water flow directly overflows through the overflow hole 167.

[0068] Exemplarily, an overflow water replenishment channel 122 is provided inside the basin body 120. The top of the overflow water replenishment channel 122 communicates with the bottom end of the overflow connection channel 165, and the bottom of the overflow water replenishment channel 122 communicates with the liquid outlet chamber 132. When the water tank 160 fills with water through the water inlet valve 164, the water flow in the overflow connection channel 165 enters the liquid outlet chamber 132 through the overflow water replenishment channel 122 and then flows into the water guide ring 130 and the washing pipe 140. It can be understood that in the embodiments of the application, the bottom end of the overflow water replenishment channel 122 can also directly communicate with the bottom of the water guide ring 130.

[0069] Since the service life of the toilet 100 is relatively long, and the check valve 170 may be damaged due to frequent changes in its state during the long-term use of the toilet 100, it may be necessary to replace the check valve 170 separately.

[0070] Please refer to Figures 4-9 , exemplarily, the check valve 170 includes a valve body 1701 and a connecting portion 1702. The valve body 1701 is configured such that water flow can flow unidirectionally into the basin body 120; the connecting portion 1702 is used for detachably connecting with the injection hole 111, which facilitates the installation of the check valve 170 during production and also facilitates the replacement of the check valve 170 as needed during use.

[0071] It can be understood that in the embodiments of the present application, the setting manner in which the valve body 1701 enables water flow to flow unidirectionally into the basin body 120 is not limited. When the drain pipe 150 supplies water to the injection chamber 110 and the water flow impacts the valve body 1701 in the positive direction, it can open the water flow channel by sliding or rotating; after the drain pipe 150 stops supplying water to the injection chamber 110 and the positive impact of the water flow on the valve body 1701 disappears, it can keep the water flow channel closed by elastic force or gravity.

[0072] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 10 , in some possible implementation schemes, the valve body 1701 includes a first housing 171, a first seal 172 and a restoring member. The first housing 171 is connected to the connecting portion 1702, and the first housing 171 has a first water inlet 1711 communicating with the injection hole 111. The first seal 172 has a first position for sealing the first water inlet 1711 and a second position for opening the first water inlet 1711. When the first seal 172 is in the first position, the check valve 170 is in the first working state, as shown in Figure 4 ; when the first seal 172 is in the second position, the check valve 170 is in the second working state, as shown in Figure 5As shown. The return member is connected between the first housing 171 and the first seal 172. The return member is configured to drive the first seal 172 to a first position and allow the first seal 172 to move from the first position to a second position under the impact of the water flow flowing into the basin 120. During flushing, the restoring force generated by the return member on the first seal 172 buffers the movement of the first seal 172, so that the first seal 172 can move smoothly to the second position under the impact of the water flow; after flushing is completed, the restoring force generated by the return member on the first seal 172 enables the first seal 172 to automatically return to the first position, making the reliability of opening and closing the one-way valve 170 good.

[0073] It can be understood that in the embodiments of the present application, the setting manner of the return member is not limited. The return member can be provided with an elastic telescopic member 1732, such as a telescopic spring; the return member can also be provided with an elastic torsion member, such as a torsion spring; the return member can also be provided with an elastic member made of an elastic material, such as an elastic column.

[0074] In a first type of embodiment, the return member is provided with an elastic telescopic member 1732 and enables the first seal 172 to slide between the first position and the second position.

[0075] Exemplarily, the first housing 171 has a flowing water cavity communicating with the first water inlet 1711. The first seal 172 is slidably sleeved in the flowing water cavity of the first housing 171. The return member includes a guiding member 1731 and an elastic telescopic member 1732. The axial direction of the guiding member 1731 is parallel to the axial direction of the first housing 171. The first end of the guiding member 1731 is connected to the first seal 172, the second end of the guiding member 1731 is slidably connected to the first housing 171, and the elastic telescopic member 1732 abuts between the first seal 172 and the first housing 171. Optionally, an installation seat 1712 is provided in the flowing water cavity of the first housing 171. The second end of the guiding member 1731 is slidably connected to the installation seat 1712 along the axial direction of the first housing 171, and the elastic telescopic member 1732 abuts between the seal and the installation seat 1712.

[0076] In the above embodiments, the elastic expansion member 1732 is provided as a return member. Under the impact of the water flow flowing into the basin 120, the first seal 172 can slide from the first position to the second position. Due to the good stability of the elastic expansion member 1732 during the expansion and contraction process and the good stability of the sliding movement mode, the first seal 172 can move stably between the first position and the second position. Since the water pressure in the toilet 100 is limited, during flushing, the first seal 172 slides from the first position to the second position by compressing the elastic expansion member 1732, and the water flow in the injection chamber 110 can easily wash away the first seal 172, and the valve body 1701 has high sensitivity to open the water flow channel under the impact of the water flow flowing into the basin 120. At the same time, since the toilet 100 will perform flushing operations frequently during use, the elastic expansion member 1732 has a high number of impact deformation resistances, so that the valve body 1701 can have a long service life.

[0077] In an exemplary embodiment, the valve body 1701 works in the injection chamber 110 through the injection hole 111. One end of the first housing 171 away from the connecting portion 1702 is located in the inner cavity of the injection chamber 110. The first water inlet 1711 is opened on the end surface of the first housing 171 away from the connecting portion 1702. When the first seal 172 is in the second position, there is a water flow gap 1713 for water flow to pass through between the first seal 172 and the first housing 171. The water flow gap 1713 can reduce the sliding friction between the first seal 172 and the first housing 171 when the first seal 172 moves between the first position and the second position, so that the water flow in the injection chamber 110 can more easily wash away the first seal 172, and the valve body 1701 has higher sensitivity to open the water flow channel under the impact of the water flow flowing into the basin 120.

[0078] Optionally, the first seal 172 is a first seal baffle. The end surface of the first housing 171 away from the connecting portion 1702 has a flanging inner edge, and the flanging inner edge is arranged along the circumference of the first housing 171 and encloses the first water inlet 1711. When the first seal 172 is in the first position, the first seal 172 abuts against the flanging inner edge and seals the first water inlet 1711. Exemplarily, a first seal gasket is provided on one side of the first seal baffle close to the flanging inner edge for the first seal 172 to abut against the flanging inner edge to seal the first water inlet 1711 when the first seal 172 is in the first position, so that the first seal 172 has good sealing performance when cooperating with the first water inlet 1711.

[0079] Exemplarily, in an implementation scheme in which the first shell 171 is provided with a flanged inner edge, the outer diameter of the first sealing baffle is smaller than the inner diameter of the first shell 171, and the entire side wall of the first sealing baffle in the circumferential direction has a gap with the inner wall of the first shell 171. When the first sealing baffle is in the second position, the water flow gap 1713 is distributed around the entire circumference of the first sealing baffle, which can avoid sliding friction between the first sealing baffle and the first shell 171 when the first sealing baffle moves between the first position and the second position, thereby making the sliding resistance of the first sealing baffle smaller.

[0080] It can be understood that in the embodiment of the present application, in the implementation scheme where the first shell 171 is provided with a flanged inner edge, the water flow gap 1713 is not limited to being distributed around the entire circumference of the first sealing baffle. For example, at least one water flow groove for water flow can be recessed on the edge of the first sealing baffle in the circumferential direction, and the groove wall of the water flow groove and the inner wall of the first shell 171 form the water flow gap 1713. In addition, in the implementation scheme where the water flow gap 1713 is distributed around the entire circumference of the first sealing baffle, it is not limited to the method where the first shell 171 is provided with a flanged inner edge. For example, the first shell 171 can be provided in a method where the inner diameter gradually decreases from the end close to the first water inlet 1711 to the end away from the first water inlet 1711.

[0081] Furthermore, the mounting seat 1712 is provided with a channel (not shown) that allows water to flow from the side close to the first water inlet 1711 to the side away from the first water inlet 1711, so that the water flowing through the water flow gap 1713 can be sprayed into the basin body 120 through the channel opened by the mounting seat 1712.

[0082] It should be noted that in the first type of implementation scheme in which the return member is provided with an elastic telescopic member 1732 and the first sealing member 172 is slidable between the first position and the second position, the first sealing member 172 is not limited to being a plate-like structure provided as the first sealing baffle, and the first water inlet 1711 is not limited to being opened on an end face of the first shell 171 away from the connecting portion 1702.

[0083] In another exemplary embodiment, the valve body 1701 works in the inner cavity of the basin body 120. The first sealing member 172 is set as a cylindrical structure, and the first water inlet 1711 is opened on the side wall of the first shell 171. The side wall of the first sealing member 172 and the inner wall of the first shell 171 are slidably sealed. When the first sealing member 172 is located in the first position, the side wall of the first sealing member 172 corresponds to the first water inlet 1711 and closes the first water inlet 1711; when the second sealing member is located in the second position, the side wall of the first sealing member 172 is staggered with the first water inlet 1711, so that the water flow in the first shell 171 can be sprayed into the basin body 120 from the first water inlet 1711.

[0084] In a second type of implementation, the reply member is provided with an elastic expansion member 1732 and the first seal 172 is rotated between a first position and a second position.

[0085] Exemplarily, the valve body 1701 operates within the inner cavity of the basin body 120. The reply member includes a mounting shaft and an elastic torsion member provided on the mounting shaft. The first seal 172 is a plate body. The first housing 171 and the first seal 172 are rotatably connected through the mounting shaft. The elastic torsion member includes opposite first and second torsion arms. The first torsion arm is connected to the first housing 171, and the second torsion arm is connected to the first seal 172. Under the impact of the water flow flowing into the basin body 120, the first seal 172 can rotate from the first position to the second position. Optionally, a second gasket is provided on one side of the first seal 172 close to the first water inlet 1711 for abutting against the opening edge of the first water inlet 1711 when the first seal 172 is in the first position to seal the first water inlet 1711, so that the first seal 172 has better sealing performance when cooperating with the first water inlet 1711.

[0086] In the above implementation, the elastic torsion member is provided as the reply member, so that the first seal 172 moves between the first position and the second position by rotating. When the first seal 172 changes from the first position to the second position, it flips towards the inside of the basin body 120. When the first seal 172 is in the second position, the water inlet can reach a larger opening degree, so that the water flow flowing into the inner cavity of the basin body 120 can better meet the water spraying requirements for the sewage outlet 121 of the basin body 120.

[0087] Please refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 11 , in some other possible implementations, the valve body 1701 includes a second housing 174, a second sealing baffle 175 and a connecting shaft 176. The second housing 174 is connected to the connecting portion 1702. The second housing 174 has a second water inlet 1741 communicating with the injection hole 111. The second sealing baffle 175 is rotatably connected to the second housing 174 through the connecting shaft 176. The second sealing baffle 175 has a third position for sealing the second water inlet 1741 and a fourth position for opening the second water inlet 1741. When the second sealing baffle 175 is in the third position, the check valve 170 is in the third working state, as shown in Figure 7 ; when the second sealing baffle 175 is in the fourth position, the check valve 170 is in the fourth working state, as shown in Figure 8 . The second sealing baffle 175 moves between the third position and the fourth position by rotating. When the second sealing baffle 175 is in the fourth position, the water inlet can reach a larger opening degree, so that the water flow flowing into the inner cavity of the basin body 120 can better meet the water spraying requirements for the sewage outlet 121 of the basin body 120.

[0088] The connecting shaft 176 is connected between the top of the second housing 174 and the second sealing baffle 175. The average density of the second sealing baffle 175 is greater than the density of water. The second sealing baffle 175 is configured to be able to press on top of the second water inlet 1741 when in the third position, and can rotate from the third position to the fourth position under the impact of the water flow flowing into the basin body 120. When the second sealing baffle 175 is in the third position, it presses on top of the second water inlet 1741 by its own gravity to close the second water inlet 1741. The structure of the valve body 1701 is simple and is convenient to use at the injection hole 111 of the toilet 100. At the same time, since the toilet 100 will frequently perform flushing operations during use, the second sealing baffle 175 is not limited by the number of return times for gravity return, so that the valve body 1701 can have a long service life.

[0089] Optionally, a third sealing gasket is provided on one side of the second sealing baffle 175 close to the second water inlet 1741 for abutting against the opening edge of the second water inlet 1741 when the second sealing baffle 175 is in the third position to seal the second water inlet 1741, so that the second sealing baffle 175 has good sealing performance when cooperating with the second water inlet 1741.

[0090] It should be noted that in the embodiments of the present application, the average density of the second sealing baffle 175 refers to the ratio between the weight of the second sealing baffle 175 and the drainage volume of the second sealing baffle 175. It can be understood that when the second sealing baffle 175 is provided with a third sealing gasket, the weight of the second sealing baffle 175 refers to the sum of the weight of the plate body itself and the weight of the third sealing gasket, and the drainage volume of the second sealing baffle 175 refers to the sum of the volume of the plate body itself and the volume of the third sealing gasket. In addition, when the second sealing baffle 175 presses on top of the second water inlet 1741 in the third position, it does not mean that the second sealing baffle 175 must be directly above the second water inlet 1741, that is, it does not mean that the second sealing baffle 175 does not have to be in a horizontal state when in the third position; the second sealing baffle 175 can also be obliquely above the second water inlet 1741, that is, the second sealing baffle 175 can also be in an inclined state when in the third position. As Figure 11 shown, when the second sealing baffle 175 presses on top of the second water inlet 1741 in the third position, it only requires that the second sealing baffle 175 is not in a vertical state, and the inclination angle α of the second sealing baffle 175 is greater than 90°, so that at least a part of the gravity of the second sealing baffle 175 can be applied to the second water inlet 1741.

[0091] It can be understood that in the embodiment of the present application, the detachable connection method between the connection portion 1702 and the injection hole 111 is not limited, for example but not limited to at least one of a snap connection, a pin connection, a threaded connection and an interference fit.

[0092] See also Figure 4 and Figure 5 In some possible implementations, the connection portion 1702 can be arranged to better adapt the valve body 1701 to work in the injection chamber 110. The valve body 1701 is configured to extend into the injection chamber 110 through the injection hole 111, which can effectively protect the valve body 1701. The connecting part 1702 includes a snap-fitting part 1771, an externally threaded tube 1772 and a first sealing assembly. The externally threaded tube 1772 is connected to the valve body 1701. The snap-fitting part 1771 is arranged at one end of the externally threaded tube 1772 close to the valve body 1701. The snap-fitting part 1771 is configured to be able to pass through the injection hole 111 and abut against the inner wall of the injection chamber 110. The first sealing assembly is used for detachable connection with the externally threaded tube 1772, and when the snap-fitting part 1771 abuts against the inner wall of the injection chamber 110, it abuts against the outer wall of the injection chamber 110 and closes the gap between the inner wall of the injection hole 111 and the outer wall of the externally threaded tube 1772. The connection between the one-way valve 170 and the injection hole 111 is convenient and has good sealing performance.

[0093] Exemplarily, the first sealing assembly includes a first sealing gasket 1773 and a locking nut 1774. The first sealing gasket 1773 is slidably sleeved on the external threaded tube 1772, and is used to abut against the outer wall of the injection chamber 110 and close the gap between the inner wall of the injection hole 111 and the outer wall of the external threaded tube 1772. The locking nut 1774 is threadedly connected to the external threaded tube 1772, and is used to tighten the first sealing gasket 1773 against the outer wall of the injection chamber 110.

[0094] See also Figure 6 Furthermore, the wall of the injection hole 111 is axially recessed with a buckle slot 112 for slidingly cooperating with the buckle 1771, so that the buckle 1771 can pass through the injection hole 111 through the buckle slot 112; after passing through the injection hole 111 through the buckle slot 112, the buckle 1771 is rotated to stagger with the buckle slot 112 so that the buckle 1771 abuts against the inner wall of the injection chamber 110. The buckle 1771 can easily pass through the injection hole 111 through the buckle slot 112, making it more convenient to install and remove the one-way valve 170 in the injection hole 111.

[0095] It can be understood that in the embodiments of the present application, it is not limited to providing a snap chute 112 in the injection hole 111 for the snap member 1771 to pass through the injection hole 111. For example, the snap member 1771 can also be set as an elastic member that can be in interference fit with the injection hole 111. When the snap member 1771 passes through the injection hole 111, it undergoes extrusion deformation so that the snap member 1771 can move within the injection hole 111; after the snap member 1771 passes through the injection hole 111, the deformation disappears.

[0096] Please refer to Figures 7-9 , in some other possible implementation schemes, the setting of the connecting portion 1702 can be well adapted to the operation of the valve body 1701 within the basin body 120. The valve body 1701 is located in the inner cavity of the basin body 120. The connecting portion 1702 includes a connecting sleeve 1781 and a second sealing washer 1782. The connecting sleeve 1781 communicates with the valve body 1701, and the second sealing washer 1782 is sleeved between the outer wall of the connecting sleeve 1781 and the inner wall of the injection hole 111. The connection between the one-way valve 170 and the injection hole 111 is convenient and has good sealing performance; the structure of the connecting portion 1702 is simple and is convenient to use in the injection hole 111 of the toilet 100.

[0097] In the toilet 100 provided by the embodiments of the present application, the injection hole 111 is opened in the injection chamber 110 located below the water storage surface, and the water guiding ring 130 is communicated with the injection chamber 110 located below the water storage surface through the washing pipe 140, which can effectively avoid the loss of the flushing kinetic energy caused by the air escaping from the pipeline, so that the injection hole 111 has better flushing kinetic energy. The injection chamber 110 is provided at the water outlet end of the drain pipe 150, which is convenient for the installation of the one-way valve 170; when the drainage stops, the setting of the one-way valve 170 can prevent the dirt in the inner cavity of the basin body 120 from flowing back into the injection chamber 110 and diluting into the washing pipe 140, and can effectively prevent the basin body 120 from being contaminated by dirt during use. When the toilet 100 is provided with a snap chute 112 for slidingly cooperating with the snap member 1771 along the axial direction of the injection hole 111, it is convenient for the installation and replacement of the one-way valve 170 having the snap member 1771 in the injection hole 111.

[0098] A one-way valve 170 for the injection hole 111 of the toilet 100 provided by the embodiments of the present application is convenient for the valve body 1701 to operate within the injection chamber 110 and can effectively protect the valve body 1701. The connecting portion 1702 of the one-way valve 170 passes through the injection hole 111 by means of a snap and abuts against the inner wall of the injection chamber 110, and then is sealed and fixed on the outer wall of the injection chamber 110. The connection between the one-way valve 170 and the injection hole 111 is convenient and has good sealing performance.

[0099] Another one-way valve 170 for the injection hole 111 of the toilet 100 provided by the embodiment of the present application facilitates the operation of the valve body 1701 in the basin body 120 and is convenient to install. The connection part 1702 of the one-way valve 170 is sealed through the connection sleeve 1781 and the second sealing washer 1782, and the connection between the one-way valve 170 and the injection hole 111 is convenient and has good sealing performance.

[0100] The foregoing is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
