[0041] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0042] In an embodiment of the present invention, a flushing valve assembly is provided for opening and closing corresponding pipes when a toilet is flushed, so that water flows through the opened water pipes to flush corresponding positions of the toilet. Figures 1 to 3 The flushing valve group includes a valve group 100 and a driving mechanism 200. The driving mechanism 200 is used to control the valve group 100 so that the valve group 100 controls the opening and closing of the corresponding pipeline. The valve group 100 includes a jet valve 110 and a scrubbing valve 120. The jet valve 110 is used to open and close the jet pipeline 410, and the scrubbing valve 120 is used to open and close the scrubbing pipeline 420. When the jet valve 110 is opened, water flows through the jet pipeline 410 to flush the dirt at the bottom of the toilet. When the scrubbing valve 120 is opened, water flows through the scrubbing pipeline 420 to flush the toilet skirt.

[0043] The driving mechanism 200 includes a first swing arm 210, a second swing arm 220, a driving shaft 230 and a driving element 240. The first swing arm 210 is movably connected to the injection valve 110, and the second swing arm 220 is movably connected to the scrubbing valve 120. The driving shaft 230 includes a first driving portion 231 and a second driving portion 232 arranged along its axial direction. The first swing arm 210 and the first driving portion 231 correspond to each other in the radial direction of the driving shaft 230, and the second swing arm 220 and the second driving portion 232 correspond to each other in the radial direction of the driving shaft 230; the driving element 240 is connected to the driving shaft 230 and is used to drive the driving shaft 230 to rotate. When the driving shaft 230 rotates, the first driving portion 231 cooperates with the first swing arm 210 to cause the first swing arm 210 to trigger the injection valve 110 to open or close, and the second driving portion 232 cooperates with the second swing arm 220 to cause the second swing arm 220 to trigger the scrubbing valve 120 to open or close.

[0044] Specific, combined Figure 4The first driving portion 231 has at least one first recessed portion 2311 recessed in the radial direction and at least one first protruding portion 2312 protruding in the radial direction, and the first recessed portion 2311 and the first protruding portion 2312 are alternately arranged along the circumference of the driving shaft 230; similarly, the second driving portion 232 has at least one second recessed portion 2321 recessed in the radial direction and at least one second protruding portion 2322 protruding in the radial direction, and the second recessed portion 2321 and the second protruding portion 2322 are alternately arranged along the circumference of the driving shaft 230.

[0045] When the flushing valve group is working, the driving element 240 drives the driving shaft 230 to rotate, and the first driving part 231 and the second driving part 232 rotate synchronously. When the driving shaft 230 rotates to the first recess 2311 and abuts against the first swing arm 210, the first swing arm 210 is not affected by the pressure of the first recess 2311, and the jet valve 110 is opened under the pressure of the water flow in the pipeline. At this time, the toilet performs jet flushing; when the driving shaft 230 rotates to the first protrusion 2312 and abuts against the first swing arm 210, the first swing arm 210 is pressurized and covers the jet valve 110, triggering the jet valve 110 to close, and the toilet stops jet flushing. When the drive shaft 230 rotates to the second recess 2321 and abuts the second swing arm 220, the second swing arm 220 is not pressed by the second recess 2321, and the washing valve 120 is opened under the pressure of the water flow in the pipeline. At this time, the toilet is washed and flushed; when the drive shaft 230 rotates to the second protrusion 2322 and abuts the second swing arm 220, the second swing arm 220 is pressurized and presses the washing valve 120, triggering the washing valve 120 to close, and the toilet stops washing and flushing.

[0046] Therefore, in the present invention, the opening and closing of the jet valve 110 and the scrubbing valve 120 are achieved by the abutment between the swing arm and the corresponding convex and concave parts on the first drive part 231 and the second drive part 232. The coordination of the actions between the swing arm and the drive part relies solely on the interaction between mechanical components, does not require the participation of magnetic force, and is not affected by water quality. The swing arm will not be corroded and stuck due to water quality problems. The opening and closing of the valve and the flushing of the toilet are more stable, and the opening and closing of the jet valve 110 and the scrubbing valve 120 are both achieved by the rotation of the drive shaft 230, which simplifies the structure of the flushing valve group and improves the flushing efficiency of the toilet.

[0047] It should be noted that the injection valve 110 and the washing valve 120 are set at the same height, and the first swing arm 210 and the second swing arm 220 are set at the same height. In this way, the drive shaft 230 can cooperate with the first swing arm 210 and the second swing arm 220 at the same time through the first drive part 231 and the second drive part 232, and control the opening and closing of the injection valve 110 and the washing valve 120.

[0048] It can be understood that since the first recess 2311 and the first convex portion 2312 are arranged at intervals along the circumference of the drive shaft 230, and the second recess 2321 and the second convex portion 2322 are arranged at intervals along the circumference of the drive shaft 230, when the drive shaft 230 rotates, the first recess 2311 and the first convex portion 2312 alternately abut against the first swing arm 210, so that the injection valve 110 is alternately opened and closed, and the second recess 2321 and the second convex portion 2322 alternately abut against the second swing arm 220, so that the washing valve 120 is alternately opened and closed; the timing of the injection flushing and washing flushing actions can be changed by adjusting the radial position relationship of the first recess 2311, the first convex portion 2312, the second recess 2321 and the second convex portion 2322. For example, the positions of one of the first recesses 2311 and one of the second recesses 2321 in the axial direction of the drive shaft 230 correspond to each other, that is, when the drive shaft 230 rotates to the point where the first swing arm 210 abuts the first recess 2311, the second swing arm 220 abuts the second recess 2321, the jet valve 110 and the scrub valve 120 are opened at the same time, and the toilet performs jet flushing and scrub flushing at the same time; or, the positions of one of the first protrusions 2312 and the second protrusion 2322 in the axial direction of the drive shaft 230 correspond to each other, that is, the projections formed by one of the first protrusions 2312 and one of the second protrusions 2322 along the circumferential direction of the drive shaft 230 overlap, and when the drive shaft 230 rotates to the point where the first swing arm 210 abuts the first protrusion 2312, the second swing arm 220 abuts the second protrusion 2322, the jet valve 110 and the scrub valve 120 are closed at the same time, and the toilet is in a non-flushing state.

[0049] In one embodiment, at least one first recess 2311 and a second recess 2321 are staggered in their projections along the axial direction of the drive shaft 230, and at least one first convex 2312 and a second convex 2322 are staggered in their projections along the axial direction of the drive shaft 230. Thus, when one of the first recesses 2311 abuts against the first swing arm 210, the second recess 2321 does not abut against the second swing arm 220. At this time, the toilet performs jet flushing alone. Similarly, when one of the second recesses 2321 abuts against the second swing arm 220, the first recess 2311 does not abut against the first swing arm 210. At this time, the toilet performs scrubbing flushing alone. When one of the first protrusions 2312 abuts the first swing arm 210, and the second protrusion 2322 does not abut the second swing arm 220, the jet valve 110 is closed and the scrub valve 120 is not closed, ensuring that the toilet can be scrubbed and flushed independently. Similarly, when one of the second protrusions 2322 abuts the second swing arm 220, the first protrusion 2312 does not abut the first swing arm 210. At this time, the scrub valve 120 is closed and the jet valve 110 is not closed, ensuring that the toilet can be jet-flushed independently. Therefore, the flush valve assembly has separate operating modes for scrub flushing and jet flushing, providing greater operational flexibility. The triggering timing of the first recess 2311 and the second recess 2321 can also be adjusted to coordinate scrub flushing and jet flushing, thereby improving the flushing effect of the toilet.

[0050] Furthermore, the second driving portion 232 includes at least two second recesses 2321, wherein a second convex portion 2322 is provided between the two second recesses 2321, and the projection formed by the second convex portion 2322 along the axial direction of the driving shaft 230 covers the projection formed by one of the first recesses 2311 along the circumferential direction of the driving shaft 230, and the projection formed by the first convex portion 2312 along the axial direction of the driving shaft 230 covers the two second recesses 2321, so that the axial positions of the second convex portion 2322 and the first recess 2311 correspond to each other, and the axial positions of the two second recesses 2321 and the first convex portion 2312 correspond to each other. Thus, when the two second recesses 2321 in the second drive part 232 respectively abut against the second swing arm 220, the first convex part 2312 in the first drive part 231 abuts against the first swing arm 210. At this time, the scrubbing valve 120 is opened, the jet valve 110 is closed, and the toilet is scrubbed and flushed alone; when the second convex part 2322 in the second drive part 232 abuts against the second swing arm 220, the first recess 2311 in the first drive part 231 abuts against the first swing arm 210. At this time, the scrubbing valve 120 is closed, the jet valve 110 is opened, and the toilet is spray-cleaned alone. In this way, the toilet will perform scrubbing flushing, jet cleaning, and scrubbing flushing in sequence. The first scrubbing flushing can wash away the dirt remaining in the skirt area of the toilet, allowing the dirt to flow to the bottom of the toilet. During jet flushing, the water flow directly removes the dirt at the bottom of the toilet. During the second scrubbing flushing, the skirt area of the toilet is flushed again to further remove the dirt that may be splashed onto the side wall of the toilet during jet flushing, thereby improving the flushing effect. In addition, the automatic connection between jet flushing and scrubbing flushing is realized, thereby improving the degree of automation of toilet flushing.

[0051] It can be understood that by changing the length of the first concave portion 2311 and the second concave portion 2321 in the circumferential direction of the drive shaft 230, the flushing time of the jet flushing and the scrubbing flushing can be adjusted, or by changing the number of the first concave portion 2311 and the second concave portion 2321 arranged in the circumferential direction of the drive shaft 230, the flushing times of the jet flushing and the scrubbing flushing can be adjusted. In one embodiment of the present application, Figure 4 As shown, the first driving portion 231 includes a first recess 2311 and a first convex portion 2312, and the second driving portion 232 includes two second recesses 2321 and two second convex portions 2322, wherein one second convex portion 2322 is located between the two second recesses 2321, and the second convex portion 2322 corresponds to the first recess 2311 in the axial direction of the driving shaft 230, a part of the first convex portion 2312 corresponds to the two second recesses 2321 in the axial direction of the driving shaft 230, and the other part of the first convex portion 2312 corresponds to the other second convex portion 2322 in the axial direction of the driving shaft 230; thus, the flushing valve group has a non-flushing mode, a jet flushing mode and a scrubbing flushing mode, and the two scrubbing flushings and the jet flushing are performed alternately.

[0052] In one embodiment, the first swing arm 210 can move relative to the injection valve 110, and the second swing arm 220 can move relative to the washing valve 120. When the first swing arm 210 abuts against the first convex portion 2312, the first swing arm 210 approaches the injection valve 110, so that the injection valve 110 is pressurized and closed. When the first swing arm 210 abuts against the first concave portion 2311, the first swing arm 210 is moved away from the injection valve 110 by the water flow pressure, and the injection valve 110 is no longer pressurized and opened. Similarly, when the second swing arm 220 abuts against the second convex portion 2322, the second swing arm 220 approaches the washing valve 120, so that the washing valve 120 is pressurized and closed. When the second swing arm 220 abuts against the second concave portion 2321, the second swing arm 220 is moved away from the washing valve 120 by the water flow pressure, and the washing valve 120 is no longer pressurized and opened.

[0053] Specifically, such as Figure 2 The flushing valve group includes a bracket 300, the valve group 100 and the driving mechanism 200 are both installed on the bracket 300, the first swing arm 210 and the second swing arm 220 are both slidably connected to the bracket 300, and the first swing arm 210 is supported by the first protrusion 2312 or the water flow pressure and can move relative to the bracket 300, so as to realize the opening and closing control of the injection valve 110 by the first swing arm 210, and the second swing arm 220 is supported by the second protrusion 2322 or the water flow pressure and can move relative to the bracket 300, so as to realize the opening and closing control of the washing valve 120 by the second swing arm 220.

[0054] In another embodiment, the first swing arm 210 can rotate relative to the injection valve 110, and the second swing arm 220 can rotate relative to the washing valve 120. When the first swing arm 210 abuts against the first convex portion 2312, the first swing arm 210 rotates toward the injection valve 110, so that the injection valve 110 is pressurized and closed. When the first swing arm 210 abuts against the first concave portion 2311, the first swing arm 210 is rotated back toward the injection valve 110 by the water flow pressure, and the injection valve 110 is no longer pressurized and opened; similarly, when the second swing arm 220 abuts against the second convex portion 2322, the second swing arm 220 rotates toward the washing valve 120, so that the washing valve 120 is pressurized and closed. When the second swing arm 220 abuts against the second concave portion 2321, the second swing arm 220 is rotated back toward the washing valve 120 by the water flow pressure, and the washing valve 120 is no longer pressurized and opened.

[0055] Specifically, the flushing valve group includes a bracket 300, the valve group 100 and the driving mechanism 200 are both installed on the bracket 300, the first swing arm 210 and the second swing arm 220 are both rotatably connected to the bracket 300, the first swing arm 210 is supported by the first protrusion 2312 or the water flow pressure and can rotate relative to the bracket 300, so that the first swing arm 210 can control the opening and closing of the injection valve 110, and the second swing arm 220 is supported by the second protrusion 2322 or the water flow pressure and can rotate relative to the bracket 300, so that the second swing arm 220 can control the opening and closing of the washing valve 120.

[0056] Furthermore, the upper end of the first swing arm 210 is rotatably connected to the bracket 300, and the lower end of the first swing arm 210 is supported by the first protrusion 2312 and rotates toward the injection valve 110, thereby blocking the pressure relief hole of the injection valve 110 and closing the injection valve 110. The upper end of the second swing arm 220 is rotatably connected to the bracket 300, and the lower end of the second swing arm 220 is supported by the second protrusion 2322 and rotates toward the scrub valve 120, thereby blocking the pressure relief hole of the scrub valve 120 and closing the scrub valve 120. The first and second swing arms 210, 220 are configured so that their upper ends are rotatably connected to the bracket 300. The first and second swing arms 210, 220 naturally droop under their own weight, covering the pressure relief hole and preventing the flushing valve assembly from releasing pressure when the flushing operation is not being performed.

[0057] Combine Figure 3 and Figure 5 The first swing arm 210 has a first blocking portion 211 at its lower end. The first blocking portion 211 is positioned toward the injection valve 110. The cross-section of the first blocking portion 211 is no smaller than the diameter of the first pressure relief hole 111 of the injection valve 110. When the first swing arm 210 is supported by the first protrusion 2312, the first blocking portion 211 can completely block the first pressure relief hole 111 of the injection valve 110. Similarly, the second swing arm 220 has a second blocking portion 221 at its lower end. The second blocking portion 221 is positioned toward the flushing valve 120. The cross-section of the second blocking portion 221 is no smaller than the diameter of the second pressure relief hole 121 of the flushing valve 120. When the second swing arm 220 is supported by the second protrusion 2322, the second blocking portion 221 can completely block the second pressure relief hole 121 of the flushing valve 120.

[0058] Furthermore, a first limiting portion 212 is provided at the lower end of the first swing arm 210. The first limiting portion 212 is disposed toward the injection valve 110 and surrounds the exterior of the first blocking portion 211. The protruding length of the first limiting portion 212 toward the injection valve 110 is no less than the protruding length of the first blocking portion 211 toward the injection valve 110. When the first swing arm 210 is supported by the first protruding portion 2312, the first blocking portion 211 blocks the pressure relief hole of the injection valve 110. Simultaneously, the first limiting portion 212 abuts against a portion of the injection valve 110, preventing the first blocking portion 211 from excessively squeezing the pressure relief hole. Furthermore, the abutment between the first limiting portion 212 and the injection valve 110 positions the first blocking portion 211 within a sealed cavity, thereby enhancing the sealing effect of the first swing arm 210 on the pressure relief hole. Similarly, a second limiting portion 222 is provided at the lower end of the second swing arm 220. The second limiting portion 222 is disposed toward the wash valve 120 and surrounds the exterior of the second blocking portion 221. The protruding length of the second limiting portion 222 toward the wash valve 120 is no less than the protruding length of the second blocking portion 221 toward the wash valve 120. When the second swing arm 220 is supported by the second protruding portion 2322, the second blocking portion 221 blocks the pressure relief hole of the wash valve 120. Simultaneously, the second limiting portion 222 abuts against a portion of the wash valve 120, preventing the second blocking portion 221 from excessively squeezing the pressure relief hole. Furthermore, the abutment between the second limiting portion 222 and the wash valve 120 positions the second blocking portion 221 within a sealed cavity, thereby enhancing the sealing effect of the second swing arm 220 on the pressure relief hole.

[0059] In one embodiment, the lower end of the first swing arm 210 is further provided with a first support rib 213 that protrudes toward the first driving portion 231. The first support rib 213 corresponds to the position of the first driving portion 231 and can abut against the first protrusion 2312 or the first recess 2311. This facilitates the cooperation between the first swing arm 210 and the first driving portion 231 and prevents interference between the first driving portion 231 and the first swing arm 210 when the driving shaft 230 rotates. Similarly, the lower end of the second swing arm 220 is further provided with a second support rib 223 that protrudes toward the second driving portion 232. The second support rib 223 corresponds to the position of the second driving portion 232 and can abut against the second protrusion 2322 or the second recess 2321. This facilitates the cooperation between the second swing arm 220 and the second driving portion 232 and prevents interference between the second driving portion 232 and the second swing arm 220 when the driving shaft 230 rotates.

[0060] It can be understood that the driving element 240 can be a non-powered component, that is, the user manually rotates the driving element 240 so that the driving element 240 drives the driving shaft 230 to rotate, thereby achieving toilet flushing; or, the driving element 240 is configured as a power component, such as a motor, a servo, a motor, etc., and the driving element 240 can output power after being energized, and drive the driving shaft 230 to rotate, thereby achieving toilet flushing.

[0061] In order to prevent the flush valve group from being unable to flush the toilet when the power is off, in one embodiment, the flush valve group is also provided with a manual flushing mode, so that the flush valve group can also be manually operated to flush the toilet when the power is off. Figure 2 As shown, the drive mechanism 200 further includes a manual member 250, which is connected to the drive shaft 230 and can drive the drive shaft 230 to rotate. The drive element 240 is movably connected to the drive shaft 230. The drive element 240 is configured to drive the drive shaft 230 to rotate when powered. When powered, the user can directly trigger the drive element 240, which transmits power to the drive shaft 230, causing the drive shaft 230 to rotate and flush the toilet. When the power is off, the user rotates the manual member 250, which drives the drive shaft 230 to rotate and flush the toilet. During this process, the drive shaft 230 can disengage from the drive element 240, overcoming the obstruction of the drive element 240 to the rotation of the drive shaft 230.

[0062] Therefore, in a power outage, the user can also manually flush the toilet by operating the manual part 250, and when the drive shaft 230 rotates under the drive of the manual part 250, it can also open and close the spray valve 110 and the flushing valve 120, so that the toilet can be flushed and sprayed.

[0063] It should be noted that in the present application, the jet valve 110, the flushing valve 120 and the driving mechanism 200 are all located above the liquid level of the toilet water tank. On the one hand, the pressure relief holes of the jet valve 110 and the flushing valve 120 can be directly connected to the external atmosphere, which can increase the pressure difference of the pressure relief holes and ensure that the jet valve 110 and the flushing valve 120 can be fully opened or closed; on the other hand, the driving mechanism 200 does not contact the water in the water tank, and can also avoid the corrosion of the driving mechanism 200 by the water in the water tank, so that the driving mechanism 200 is not affected by the water quality in the water tank, and the flushing of the flushing valve group is more stable.

[0064] The drive shaft 230 is rotatably connected to the bracket 300, and the bracket 300 supports the drive shaft 230. One end of the drive shaft 230 is connected to the manual member 250, and the other end is connected to the driving element 240. The manual member 250 and the driving element 240 can both drive the drive shaft 230 to rotate simply by rotating, making it more convenient for the driving element 240 and the manual member 250 to drive the drive shaft 230.

[0065] In one embodiment, the driving element 240 can move relative to the driving shaft 230 along the axial direction of the driving shaft 230 to connect or disconnect with the driving shaft 230. When the driving element 240 moves toward the driving shaft 230, the driving shaft 230 is connected to the driving element 240. At this time, the driving element 240 can drive the driving shaft 230 to rotate. When the driving element 240 moves away from the driving shaft 230, the driving shaft 230 is disengaged from the driving element 240. At this time, the driving element 240 no longer interferes with the rotation of the driving shaft 230. Specifically, one of the driving element 240 and the driving shaft 230 is provided with a plug-in portion, and the other is provided with a plug-in hole. When the driving element 240 moves toward the driving shaft 230, the plug-in portion is plugged into the plug-in hole, and the hole wall of the plug-in hole and the plug-in portion are limited to each other in the circumferential direction of the driving shaft 230. At this time, the driving element 240 can drive the driving shaft 230 to rotate to flush the toilet; when the driving element 240 moves away from the driving shaft 230, the plug-in portion withdraws from the plug-in hole, and the driving element 240 is separated from the driving shaft 230.

[0066] In another embodiment, combined Figure 2 and Figure 6 The driving mechanism 200 further includes an elastic member 260, a fixing seat 270, a first engaging tooth 280 and a second engaging tooth 290. The first engaging tooth 280 is connected to the driving element 240. The fixing seat 270 is connected to one end of the driving shaft 230 facing the driving element 240. The two ends of the elastic member 260 are respectively connected to the fixing seat 270 and the second engaging tooth 290, so that the second engaging tooth 290 can float relative to the driving shaft 230 along the axial direction of the driving shaft 230. Figure 6 and Figure 7 The first engaging tooth 280 is provided with a first abutting surface 281 and a first guide surface 282 on both sides along the circumference of the driving shaft 230, and the second engaging tooth 290 is provided with a second abutting surface 291 and a second guide surface 292 on both sides along the circumference of the driving shaft 230. The first abutting surface 281 and the second abutting surface 291 abut against each other along the circumference of the driving shaft 230, and the first guide surface 282 and the second guide surface 292 can slide relative to each other.

[0067] When the driving shaft 230 is driven to rotate by the driving element 240, the second engaging tooth 290 is held by the elastic member 260 and has a tendency to move toward the first engaging tooth 280, so that the first abutting surface 281 of the first engaging tooth 280 and the second abutting surface 291 of the second engaging tooth 290 maintain an abutting state, and the first engaging tooth 280 and the second engaging tooth 290 are mutually limited in the circumferential direction of the driving shaft 230. The driving element 240 can drive the driving shaft 230 to rotate to achieve toilet flushing; when the driving shaft 230 is driven to rotate by rotating the manual member 250, the second engaging tooth 290 rotates toward the direction away from the first abutting surface 281 and the second abutting surface 291. At this time, the first engaging tooth 280 and the second engaging tooth 290 are mutually limited in the circumferential direction of the driving shaft 230. The first abutment surface 281 gradually moves away from the second abutment surface 291, and the first guide surface 282 gradually approaches the second guide surface 292. When the first guide surface 282 contacts the second guide surface 292, driven by the manual member 250, the first guide surface 282 and the second guide surface 292 move relative to the axial direction of the drive shaft 230, the elastic member 260 is compressed, and the second engaging tooth 290 moves away from the second engaging tooth 290 along the axial direction of the drive shaft 230 until the second engaging tooth 290 jumps over the first engaging tooth 280. Then the elastic member 260 recovers, and the second engaging tooth 290 moves toward the first engaging tooth 280, and the first engaging tooth 280 and the second engaging tooth 290 abut against each other again. In this way, when the manual part 250 drives the drive shaft 230 to rotate, the drive shaft 230 cooperates with the first swing arm 210 and the second swing arm 220 to achieve toilet flushing in a power outage state; and, since the second engaging tooth 290 can move relative to the first engaging tooth 280 under the elastic force of the elastic part 260, the first engaging tooth 280 and the second engaging tooth 290 can separate and abut each other during the rotation of the drive shaft 230, thereby avoiding the connection between the driving element 240 and the drive shaft 230 from interfering with the rotation of the drive shaft 230.

[0068] It should be noted that, along the driving direction of the driving element 240 on the driving shaft 230, the second abutment surface 291 is located on the front side of the first abutment surface 281, so that the first abutment surface 281 can provide a forward supporting force to the first abutment surface 281, so that the second engaging tooth 290 rotates following the first engaging tooth 280; and, the manual member 250 and the driving element 240 have the same driving direction on the driving shaft 230. When the manual member 250 drives the driving shaft 230 to rotate, the second engaging tooth 290 rotates forward and away from the first engaging tooth 280, which is in line with the movement trend that the first abutment surface 281 and the second abutment surface 291 gradually move away from each other, and the first guide surface 282 and the second guide surface 292 gradually approach each other.

[0069] It will be appreciated that to facilitate relative sliding between the first guide surface 282 and the second guide surface 292, and to facilitate the second engaging tooth 290 jumping over the first engaging tooth 280, the first guide surface 282 and the second guide surface 292 are configured as arcuate or curved surfaces to reduce resistance encountered by the second engaging tooth 290 when jumping. Furthermore, a plurality of first engaging teeth 280 and a plurality of second engaging teeth 290 may be provided, and the plurality of first engaging teeth 280 and the plurality of second engaging teeth 290 are arranged at intervals along the circumference of the drive shaft 230.

[0070] In one embodiment, the second engaging tooth 290 is connected to the fixed seat 270 in an axial sliding manner along the drive shaft 230, and the fixed seat 270 guides the movement of the second engaging tooth 290, so that the cooperation between the first engaging tooth 280 and the second engaging tooth 290 is more stable, and the first engaging tooth 280 and the drive seat are limited to each other in the circumferential direction of the drive shaft 230, and the first engaging tooth 280 can rotate synchronously with the fixed seat 270 and the drive shaft 230.

[0071] Reference Figure 3 In the present invention, valve assembly 100 also includes a water replenishment valve 130, which is used to open and close the water replenishment pipeline 430. Located above jet valve 110 and flush valve 120, water replenishment valve 130, when opened, replenishes water into the water tank through the water replenishment pipeline 430. Thus, jet valve 110, flush valve 120, and water replenishment valve 130 are all integrated into valve assembly 100. After the toilet completes both a flush and jet flush, if the liquid level in the water tank is low, water replenishment valve 130 opens to replenish the water tank, improving the automation of the toilet flushing process.

[0072] The present invention also provides a flushing system, comprising the flushing valve assembly described above, and a flushing pipe assembly, the flushing pipe assembly comprising a jetting pipe 410, a scrubbing pipe 420, and a water inlet pipe 440. The jetting pipe 410 is connected to the jetting valve 110, and the scrubbing pipe 420 is connected to the scrubbing valve 120. The jetting valve 110 and the scrubbing valve 120 are both connected to the water inlet pipe 440, so that the water inlet pipe 440 can simultaneously supply water to the jetting pipe 410 and the scrubbing pipe 420. The water inlet pipe 440 is connected to an external tap water pipe. When the jetting valve 110 is opened, water in the water inlet pipe 440 enters the jetting pipe 410 to jet-flush the toilet. When the scrubbing valve 120 is opened, water in the water inlet pipe 440 enters the scrubbing pipe 420 to scrub and flush the toilet.

[0073] It should be noted that the water supply valve 130 is connected to the water inlet pipe 440. When the water supply valve 130 is opened, the water in the water inlet pipe 440 enters the water supply pipe 430 to replenish the water tank. In this way, the wash pipe 420, the spray pipe 410, and the water supply pipe 430 share the water supply pipe 440. By controlling the opening and closing of the water supply valve 130, the spray valve 110, and the wash valve 120, the water in the water supply pipe 440 can be diverted to different pipes, thereby achieving water tank replenishment, toilet jet flushing, and toilet wash flushing.

[0074] It is understood that a water inlet valve should also be provided within the valve assembly 100. When the water inlet valve is opened, water from the external tap water pipe enters the water inlet pipe 440. In the present invention, the water supply valve 130, the flushing valve 120, the spray valve 110, and the water inlet valve are combined to form a one-inlet, three-outlet control valve, which has a higher valve integration level and helps reduce the production cost of the flushing system; for example, the valve assembly 100 is configured as a diaphragm valve.

[0075] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
