[0043] See also Figure 2-Figure 4The embodiment of the present invention provides a flushing valve assembly 100, which can be used in a toilet and realize the functions of brush ring flushing and siphon flushing. The flushing valve assembly 100 includes a valve body 10, a valve core 20 and a driving motor 30. The valve core 20 is rotatably mounted on the valve body 10. The driving motor 30 is mounted on the valve body 10 and connected to the valve core 20. The valve core 20 is used to realize the switching of the water path in the valve body 10 to control the water outlet direction. The driving motor 30 is used to drive the valve core 20 to rotate relative to the valve body 10.

[0044] Please also read Figure 5 , wherein the valve body 10 comprises an inlet pipe 11 and at least two outlet pipes (12, 13), one end of the at least two outlet pipes being connected to one end of the inlet pipe 11 respectively, and a receiving cavity 101 is provided at the connection between the at least two outlet pipes and the inlet pipe 11. The valve core 20 comprises a valve core body 21, the valve core body 21 being rotatably mounted in the receiving cavity 101, the valve core body 21 being provided with a sealing arc surface 201, the arc length of the sealing arc surface 201 being adapted to the pipe opening of one end of the outlet pipe close to the receiving cavity 101, the valve core body 21 being used to rotate and switch between the at least two outlet pipes, and to close one of them with the sealing arc surface 201. wherein when the sealing arc surface 201 closes one of the at least two outlet pipes, the two ends of the sealing arc surface 201 along its own arc length direction are respectively fitted to the pipe opening edge of the corresponding outlet pipe close to the receiving cavity 101.

[0045] The flushing valve assembly 100 provided in the embodiment of the present invention is configured with a sealing arc surface 201 whose arc length is matched with the pipe mouth of the water outlet pipe on the valve core body 21, so that when the sealing arc surface 201 closes the pipe mouth of the water outlet pipe, the two ends of the sealing arc surface 201 along its own arc length direction are respectively fitted to the pipe mouth edge of the water outlet pipe, thereby avoiding the formation of a dead angle between the valve core body 21 and the inner wall of the valve body 10 and the precipitation of mud and impurities, thereby avoiding damage to the valve core 20 and / or the valve body 10 and causing the valve core 20 to rotate and leak, thereby ensuring the normal operation and service life of the flushing valve assembly 100.

[0046] For the valve body 10 described above, the valve body 10 includes an inlet pipe 11 and at least two outlet pipes, both of which are hollow tubular structures, one end of the at least two outlet pipes are respectively connected to one end of the inlet pipe 11, the at least two outlet pipes are both in communication with the inner cavity of the inlet pipe 11, and the connection between the at least two outlet pipes and the inlet pipe 11 forms a receiving chamber 101, and the receiving chamber 101 is used to receive the valve core 20. Among them, the connection between the pipe openings of two adjacent outlet pipes close to one end of the receiving chamber 101 is smoothly transitioned to form an arc-shaped side wall 102, and the pipe openings of the at least two outlet pipes close to one end of the receiving chamber 101 and the arc-shaped side wall 102 are connected to form an arc surface, and the sealing arc surface 201 can rotate around its own rotation axis along the arc surface, that is, the circular motion trajectory formed by the sealing arc surface 201 rotating around its own rotation axis is an arc surface.

[0047] In this embodiment, there are two water outlet pipes, namely the first water outlet pipe 12 and the second water outlet pipe 13. The water route of the valve body 10 is divided into two parts in the direction of the first water outlet pipe 12 and the second water outlet pipe 13 after the water inlet pipe 11 passes through the receiving chamber 101. The water inlet pipe 11 is used for external flushing water, and the first water outlet pipe 12 and the second water outlet pipe 13 are used for the water outlet of the brush ring flushing and the siphon flushing respectively. Among them, the first water outlet pipe 12, the second water outlet pipe 13 and the water inlet pipe 11 are connected to form a Y shape, that is, the valve body 10 is in a Y shape. In a specific embodiment, the valve body 10 can be an integrated structure.

[0048] In some other embodiments, the valve body 10 may also be other structural shapes, for example, a T-shape, or one end of the first water outlet pipe 12 and the second water outlet pipe 13 are respectively connected to one end of the water inlet pipe 11, and the first water outlet pipe 12 and the second water outlet pipe 13 are located on the same plane, and the water inlet pipe 11 is arranged perpendicular to the plane.

[0049] In some other embodiments, the number of water outlet pipes can be set according to actual needs, for example, three. The water path of the water inlet pipe 11 is divided into three parts in the direction of the three water outlet pipes after passing through the accommodating cavity 101. The valve core 20 rotates and switches between the three water outlet pipes and closes one of them, thereby realizing the switching of the water path in the valve body 10.

[0050] For the above-mentioned valve core 20, the valve core 20 is rotatably installed in the receiving chamber 101, and the valve core 20 can rotate relative to the valve body 10 around its own rotation axis. The valve core 20 rotates and switches between the first water outlet pipe 12 and the second water outlet pipe 13, and closes one of them, thereby realizing the switching of the water path in the valve body 10, so that the brush ring flushing and siphon flushing can be carried out in sequence according to a preset order. Among them, when the valve core 20 closes the pipe opening of the first water outlet pipe 12 close to one end of the receiving chamber 101, the second water outlet pipe 13 is connected to the water inlet pipe 11; when the valve core 20 closes the pipe opening of the second water outlet pipe 13 close to one end of the receiving chamber 101, the first water outlet pipe 12 is connected to the water inlet pipe 11. It should be noted that in actual application, the valve core 20 can be rotated around the rotation axis to a position where the water inlet pipe 11 is connected to the first water outlet pipe 12 and the second water outlet pipe 13, so as to allow the brush ring flushing and siphon flushing to be carried out simultaneously.

[0051] The valve core 20 includes a valve core body 21 and a support shaft 22. The valve core body 21 and the support shaft 22 are fixedly connected. The valve core body 21 can rotate around the central axis of the support shaft 22. The above-mentioned rotation axis is the central axis of the support shaft 22. The support shaft 22 is used to support the structure of the valve core body 21 and serve as the rotation axis of the valve core body 21.

[0052] The valve core body 21 is provided with a sealing arc surface 201, the arc length of the sealing arc surface 201 is adapted to the pipe openings of the first water outlet pipe 12 and the second water outlet pipe 13 at one end close to the receiving chamber 101, and the valve core body 21 is used to rotate and switch between the first water outlet pipe 12 and the second water outlet pipe 13, and close one of them with the sealing arc surface 201. Among them, when the valve core body 21 rotates to the sealing arc surface 201 to close the first water outlet pipe 12, the entire sealing arc surface 201 is located at the pipe opening of the first water outlet pipe 12 at one end close to the receiving chamber 101, and the two ends of the sealing arc surface 201 along its own arc length direction are respectively attached to the edge of the pipe opening of the first water outlet pipe 12 at one end close to the receiving chamber 101, and the flushing water can directly flow to the second water outlet pipe 13 along the side wall of the receiving chamber 101 close to the first water outlet pipe 12 and the side wall of the sealing arc surface 201 facing the water inlet pipe 11, as shown in FIG. Figure 3 As shown; when the valve core body 21 rotates to the sealing arc surface 201 to close the second water outlet pipe 13, the entire sealing arc surface 201 is located at the pipe opening of the second water outlet pipe 13 close to the accommodating chamber 101, and the two ends of the sealing arc surface 201 along its own arc length direction are respectively attached to the pipe opening edge of the second water outlet pipe 13 close to the accommodating chamber 101, and the flushing water can directly flow to the second water outlet pipe 13 along the side wall of the accommodating chamber 101 close to the second water outlet pipe 13 and the side wall of the sealing arc surface 201 facing the water inlet pipe 11, as shown in FIG. Figure 4 shown.

[0053] Please combine Figure 5 and Figure 6Further, the first middle section of the valve core body 21 is a fan ring, and based on the first middle section, the fan ring extends symmetrically in two opposite directions away from the first middle section to form the above-mentioned sealing arc surface 201, and the arc length of the fan ring is adapted to the pipe opening of the water outlet pipe at one end close to the receiving cavity 101. The first middle section and the support shaft 22 are arranged perpendicular to each other.

[0054] It is understandable that the width of the fan ring should not be too large to prevent the formation of dead angles between the side walls at both ends of the sealing arc surface 201 along the first mid-section direction and the inner wall of the valve body 10 .

[0055] Please also read Figure 7 Furthermore, the second middle section of the valve core body 21 is a semi-enclosed structure, and the second middle section is perpendicular to the first middle section. The two ends of the sealing arc surface 201 extend symmetrically to the two ends of the support shaft 22, and are fixedly connected to the support shaft 22, that is, the two ends of the support shaft 22 are fixedly connected to the two ends of the valve core body 21 away from the first middle section. Through the above arrangement, a hollow structure 202 is formed between the valve core body 21 and the support shaft 22. When the valve core body 21 closes the first water outlet pipe 12 or the second water outlet pipe 13 near one end of the receiving chamber 101, the flushing water can directly flow to the second water outlet pipe 13 or the first water outlet pipe 12 through the hollow structure 202 between the valve core body 21 and the support shaft 22, thereby avoiding the valve core 20 as a whole from blocking the flushing water and affecting the water outlet.

[0056] Optionally, the second middle section of the valve core body 21 is an arc structure, a rectangular structure or a trapezoidal structure, that is, the semi-enclosed structure can be one of an arc structure, a rectangular structure and a trapezoidal structure, wherein the arc structure can be a circular arc structure or an elliptical arc structure, and correspondingly, the circular motion trajectories of the circular arc structure, the elliptical arc structure, the rectangular structure and the trapezoidal structure are a sphere, an ellipsoid cylinder and a shuttle body respectively. In this embodiment, the second middle section of the valve core body 21 is an arc structure. For details, please refer to Figure 7-Figure 9 , Figure 7 The second middle cross section of the valve core body 21 is a circular arc structure. Figure 8 In other embodiments, Figure 8 The rectangular structure of the second middle cross section of the valve core body 21a of the valve core 20a is shown. Fig. 9 The trapezoidal structure of the second middle cross section of the valve core body 21 b of the valve core 20 b is shown.

[0057] In some other embodiments, the support shaft 22 may be omitted.

[0058] Please refer to Figure 7In order to enable the valve core 20 as a whole to rotate stably around the central axis of the support shaft 22, the valve core body 21 is respectively provided with a first matching structure 211 and a second matching structure 212 at both ends facing away from the support shaft 22. The first matching structure 211 and the second matching structure 212 are arranged along the central axis of the support shaft 22. The first matching structure 211 is used to connect the drive motor 30, and the second matching structure 212 is used to connect the valve body 10.

[0059] In this embodiment, the first matching structure 211 is a flat hole, and the second matching structure 212 is a round hole. The output shaft of the drive motor 30 is provided with a shaft flat position, and the output shaft of the drive motor 30 passes through the side wall of the valve body 10 and enters the receiving cavity 101, and the shaft flat position is matched with the flat hole. The side wall of the receiving cavity 101 is provided with a cylindrical protrusion, and the cylindrical protrusion is inserted into the round hole.

[0060] In some other embodiments, the first matching structure 211 is a shaft flattened part, and the second matching structure 212 is a cylindrical protrusion. The output shaft of the driving motor 30 is provided with a flattened part hole, and the output shaft of the driving motor 30 passes through the side wall of the valve body 10 and enters the receiving cavity 101, and the flattened part hole is matched with the shaft flattened part. The side wall of the receiving cavity 101 is provided with a circular hole, and the cylindrical protrusion is inserted into the circular hole.

[0061] Please refer to 10. The flushing valve assembly 100 provided in the embodiment of the present invention also includes a brush ring nozzle 40 and a siphon nozzle 50, which are respectively connected to two water outlet pipes, wherein the brush ring nozzle 40 is connected to the first water outlet pipe 12, the brush ring nozzle 40 is used to communicate with the brush ring pipe of the toilet, and spray flushing water to perform brush ring flushing on the side wall of the toilet bowl, and the flushing nozzle 41 is connected to the second water outlet pipe 13, and the siphon nozzle 50 is used to communicate with the siphon pipe of the toilet, and spray flushing water to perform siphon flushing on the bottom of the toilet bowl.

[0062] The flushing valve assembly 100 provided in the embodiment of the present invention further includes a one-way valve 60, which is connected to the valve body 10 and is used to prevent water leakage in the waterway. When the water pressure in the valve body 10 is high, that is, when the front water source supplies water, the one-way valve 60 is open; when the water pressure in the valve body 10 is low, that is, after the front water source stops supplying water, the one-way valve 60 is normally closed.

[0063] Optionally, the one-way valve 60 is disposed between the brush ring nozzle 40 and a water outlet pipe corresponding to the brush ring nozzle 40, and in a non-working state, the valve core body 21 closes a water outlet pipe corresponding to the siphon nozzle 50, or the one-way valve 60 is disposed between the siphon nozzle 50 and a water outlet pipe corresponding to the siphon nozzle 50, and in a non-working state, the valve core body 21 closes a water outlet pipe corresponding to the brush ring nozzle 40. That is, when the one-way valve 60 is connected between the brush ring nozzle 40 and the first water outlet pipe 12, in a non-working state, the one-way valve 61 normally closes the brush ring nozzle 40, and the valve core body 21 normally closes the pipe opening of the second water outlet pipe 13 at one end close to the receiving chamber 101; when the one-way valve 60 is connected between the siphon nozzle 50 and the second water outlet pipe 13, in a non-working state, the one-way valve 61 normally closes the siphon nozzle 50, and the valve core body 21 normally closes the pipe opening of the first water outlet pipe 12 at one end close to the receiving chamber 101.

[0064] It should be noted that after the flushing valve assembly 100 completes the flushing work, there is a delayed small flow of residual water inside the valve body 10 and in the pipe of the front-end water source connected to the water inlet pipe 11. The residual water flows to the outside through an outlet pipe that is not closed by the valve core 20, and since the residual water flow is small, it cannot achieve the flushing effect, resulting in a waste of water. If the residual water flows from the first outlet pipe 12 to the brush ring pipe of the toilet, it is easy to give users a bad impression that the product is leaking. In addition, if the front-end water source is not closed tightly, there will be continuous micro-leaks in the outlet pipe that is not closed by the valve core 20, resulting in a waste of water. Therefore, a one-way valve 60 needs to be set on the outlet pipe corresponding to the normally open water circuit to prevent water leakage in the water circuit.

[0065] See also Fig.11 In this embodiment, the one-way valve 60 is connected to the brush ring nozzle 40 , and in a non-working state, the valve core 20 closes a water outlet pipe corresponding to the siphon nozzle 50 .

[0066] See also Figure 12-14 The brush ring nozzle 40 includes a nozzle 41, which is provided with a flow channel 4101. The side wall of the flow channel 4101 is provided with a first step portion 4102. The two ends of the flow channel 4101 are respectively the water inlet end and the water outlet end of the brush ring nozzle 40. When water is supplied, the water flows from the water inlet end to the water outlet end.

[0067] The one-way valve 60 is accommodated in the flow channel 4101, and includes a shutoff valve 61 and an elastic member 62. The shutoff valve 61 is movably arranged in the flow channel 4101, and the shutoff valve 61 can move toward or away from the first step portion 4102 along its own axis relative to the first step portion 4102. The shutoff valve 61 is used to cut off or conduct the flow channel 4101 during the movement relative to the first step portion 4102. The elastic member 62 has an elastic restoring force, which elastically connects the shutoff valve 61 and the brush ring nozzle 40, and provides the shutoff valve 61 with an elastic force that causes the shutoff valve 61 to press against the first step portion 4102. The elastic member 62 is used to cause the shutoff valve 61 to press against the first step portion 4102 to cut off the flow channel 4101, so that water cannot flow therethrough. When the water supply pressure in the flow channel 4101 is greater than the elastic force of the elastic member 62 and overcomes the elastic force to do work, the shutoff valve 61 moves away from the first step 4102, the flow channel 4101 is open, and the elastic member 62 is elastically deformed, such as Fig.13 As shown in FIG. 4 , when the water supply pressure in the flow channel 4101 is less than the elastic force of the elastic member 62, the shutoff valve 61 is pressed against the first step portion 4102 under the action of the elastic member 62 and the flow channel 4101 is cut off, that is, the elastic member 62 recovers its elastic deformation and causes the shutoff valve 61 to move toward the first step portion 4102 and abut against the first step portion 4102, as shown in FIG. Fig.12 shown.

[0068] The brush ring nozzle 40 also includes a first locking nut 42. The outer wall of the nozzle 41 is provided with an external thread 4103. The first locking nut 42 is threadedly matched with the external thread 4103 of the brush ring nozzle 40. The outer wall of the nozzle 41 is also provided with a stop portion 4104. The first locking nut 42 can move along the external thread 4103 toward or away from the stop portion 4104. In the specific implementation process, the first locking nut 42 and the stop portion 4104 are used to cooperate together and fix the brush ring nozzle 40 to the outside. For example, when the brush ring nozzle 40 is installed on the brush ring pipe of the toilet, a mounting hole is provided on the side wall of the brush ring pipe, and one end of the nozzle 41 provided with an external thread 4103 passes through the mounting hole, and then the first locking nut 42 is threadedly matched with the external thread 4103 of the nozzle 41, and the first locking nut 42 is tightened so that the stop portion 4104 and the first locking nut 42 are respectively tightened against the two ends of the mounting hole, thereby fixing the brush ring nozzle 40 on the side wall of the brush ring pipe of the toilet.

[0069] Furthermore, in order to ensure that the brush ring nozzle 40 is fastened to the outside, the brush ring nozzle 40 also includes a first washer 43 and a second washer 44. The first washer 43 and the second washer 44 are respectively sleeved on the outer wall of the nozzle 41, and the first washer 43 abuts against the side of the stop portion 4104 opposite to the first locking nut 42, and the second washer 44 abuts against the side of the first locking nut 42 opposite to the stop portion 4104.
