[0022] Please see FIGS. 1 to 3. The present disclosure provides a flushing device, which comprises: a flushing valve 10 comprising a valve body 11 and a driving component 12, wherein the valve body 11 is arranged to be able to open under a driving action of the driving component 12; a pressing assembly 20 comprising a first housing 21, a first button 22, a first rocker 23 and a pull rope 241, wherein the first button 22 is movably arranged with respect to the first housing 21 and abuts against one end of the first rocker 23, the first rocker 23 is rotatably arranged with respect to the first housing 21, the other end of the first rocker 23 is connected to the pull rope 241, the pull rope 241 is connected to the valve body 11, and the first rocker 23 is arranged to be able to pull the pull rope 241 under the driving action of the first button 22, so as to drive the valve body 11 to open via the pull rope 241.

[0023] In this embodiment, the flushing valve 10 is provided with a driving component 12 as a flushing switch, and the valve body 11 can be driven to open by the driving component 12 for water flushing; the driving component 12 can be used as a hand-operated switch to facilitate the user to flush with water by pressing the switch by hand. The pressing assembly 20 may be used as a foot-operated switch to press the first button 22, the first button 22 pushes the first rocker 23 to rotate, the first rocker 23 pulls the pull rope 241, and the pull rope 241 drives the valve body 11 to open for water flushing, which is convenient for the user to flush with water by kicking the pressing assembly by foot. In addition, when either of the flushing switches fails, the other flushing switch can be used to accomplish timely flushing, which is to say, when the driving component 12 fails, the pressing assembly 20 can be used for flushing; and when the pressing assembly 20 fails, the driving component 12 can be used for flushing, so as to avoid an inconvenient situation.

[0024] Specifically, the center of rotation of the first rocker 23 is located between its two ends, wherein one end of the first rocker 23 abuts against the first button 22, and the other end of the first rocker 23 is connected to the pull rope 241, so that the stress direction of one end of the first rocker 23 is opposite to the movement direction of the other end, i.e., when the first button 22 is moved in a direction toward the first rocker 23, the first rocker 23 can be pushed to rotate around its center of rotation, while the pull rope 241 is pulled in a direction toward the first button 22.

[0025] Please see FIGS. 1 to 3. In some embodiments, the first button 22 comprises a button body 221 and an abutting block 222. An inclined plane is formed on the abutting block 222 at the end of the button body 221 facing the first rocker 23, the first rocker 23 is obliquely arranged in an initial state, and the inclination angle and direction of the first rocker 23 in this state are the same as those of the inclined plane, respectively.

[0026] In this embodiment, the first button 22 pushes the first rocker 23 to move by directly contacting with the first rocker 23, and there is no transmission component between them. Thus, on one hand, the structure of the pressing assembly 20 is compact, and the number of parts is reduced; on the other hand, after the first button 22 is moved, the power can be quickly transmitted to the first rocker 23, and the power of the first button 22 is prevented from being consumed by a transmission component between the first button 22 and the first rocker 23, for example, the power of the first button 22 may be consumed by the friction of the transmission component. Thus, the force required for pressing the first button 22 can be reduced.

[0027] Specifically, as described in the orientation shown in FIG. 2, the left lower part of the first rocker 23 is configured into a cambered surface, and the inclined surface of the abutting block 222 is tangent to the cambered surface. Thus, on one hand, the rotation torque of the first rocker 23 is high, and the first rocker 23 can be easily driven to rotate with small force, and the operation is labor-saving; on the other hand, the contact surface between the abutting block 222 and the first rocker 23 is small, thereby the friction between them is small, and the resistance encountered when the abutting block 222 pushes the first rocker 23 to rotate is small, and the first rocker 23 can rotate more smoothly. Continuing with the description in the orientation shown in FIG. 2, the abutting block 222 is a wedge-shaped block, and has a rounded tip formed at the right end. In the initial state, the first rocker 23 is arranged obliquely to the left from top to bottom, and the inclined plane of the abutting block 222 is also arranged obliquely to the left from top to bottom. When the button body 221 is subjected to acting force from left to right, the abutting block 222 is moved from left to right, so that it pushes the lower end of the first rocker 23 to move; the left lower part of the first rocker 23 is moved along the inclined plane of the abutting block 222 first, and the first rocker 23 rotates counterclockwise with respect to its center of rotation; when the first rocker 23 rotates to an extent that the rounded tip of the abutting block 222 abuts against the first rocker 23, the left lower part of the first rocker 23 is disengaged from the inclined plane of the abutting block 222, and the rounded tip of the abutting block 222 continues pushing the first rocker 23 to rotate counterclockwise, and the first rocker 23 pulls the pull rope 241 to move from right to left. With the arrangement of the inclined plane of the abutting block 222, on one hand, a high torque is provided for the rotation of the first rocker 23; on the other hand, when the rounded tip of the abutting block 222 abuts against the first rocker 23, the abutting block 222 pushes the first rocker 23 to rotate counterclockwise faster around its point of abutment against the first rocker 23.

[0028] Continuing with the description in the orientation shown in FIG. 2, in the initial state, the left end of the button body 221 protrudes from the left end of the first housing 21, thereby the user can press the button body 221 conveniently.

[0029] Please see FIGS. 1 to 3. In some embodiments, the pressing assembly 20 further comprises a first elastic member 25 and / or a second elastic member 26.

[0030] In this embodiment, when force is applied to the first button 22, the first elastic member 25 is compressed; when the force applied to the first button 22 disappears, the first elastic member 25 is restored to its original length by its own elastic force, thus, it drives the first button 22 to reset. As described in the orientation shown in FIG. 2, the direction of the force applied to the first button 22 is to the right, and the direction of movement of the first button 22 in the resetting process is to the left. The first elastic member 25 can reset the first button 22 by means of the elastic force, so as to avoid a problem that the first button 22 can't be pressed again after being pressed because it can't be reset to its original position. When the first button 22 is subjected to acting force, it transfers the acting force to the first rocker 23, so that the first rocker 23 rotates, and the second elastic member 26 is elastically deformed; when the acting force on the first button 22 disappears, the second elastic member 26 is restored by its own elastic force, and it drives the first rocker 23 to reset. As described in the orientation shown in FIG. 2, the direction of rotation of the first rocker 23 under the acting force of the first button 22 is counterclockwise, while the direction of rotation of the first rocker 23 in the resetting process is clockwise. The second elastic member 26 can reset the first rocker 23 by means of the elastic force. When the first button 22 is pressed next time, the first button 22 can push the first rocker 23 to rotate again, so as to avoid that the first rocker 23 can't be pushed to rotate by pressing the first button 22 again.

When the protrusion 282 is snapped into the inner wall of the hole, both the first vertical section of the first housing 21 and the first vertical section of the connecting sleeve 281 are located outside the hole, and the first vertical section of the connecting sleeve 281 can be attached to the peripheral end of the hole; with such an arrangement, on one hand, to remove the pressing assembly 20, the pressing assembly 20 can be pulled out of the hole by exerting force on the first vertical section of the first housing 21 and the first vertical section of the connecting sleeve 281, which is to say, the pressing assembly 20 can be removed conveniently; on the other hand, the button body 221 of the first button 22 can be exposed outside the hole, so that the user can use it conveniently. In the present application, both the driving component 12 and the pressing assembly 20 drive the valve body 11 to open in a non-powered driving approach without any electrical control component, and the valve body 11 is opened by means of mechanical transmission. Thus, the structure of the flushing device is simpler and more compact, and will not be damaged easily.

[0052] In the present application, the pressing assembly 20 and the driving component 12 are two separate flushing switches that do not interfere with each other, and there is no linkage between them. When the first button 22 of the pressing assembly 20 is pressed with force, the pull rope 241 pulls the pull rod 1132 for flushing, and the driving component 12 will not move in linkage; when the driving component 12 is pressed with force, the driving component 12 pushes down the second rocker 1131 to drive the pull rod 1132 for flushing, and the first button 22 of the pressing assembly 20 will not move in linkage. Therefore, the two flushing switches, i.e., the pressing assembly 20 and the driving component 12, are used independently from each other. When either flushing switch is damaged, the normal use of the other flushing switch will not be affected, which is to say, the two flushing switches will not be damaged at the same time owing to the interaction between them, and the flushing device has a simple structure and high reliability.

[0053] The present disclosure further provides a toilet bowl, which comprises a main body and the flushing device described above, wherein the flushing device is arranged on the main body.

[0054] In this embodiment, the flushing device of the toilet bowl has all the technical schemes and technical effects of the flushing device described above, and will not be further detailed here.

[0055] Specifically, the toilet bowl further comprises a water tank, a flushing valve 10 is arranged in the water tank, a pressing assembly 20 is detachably arranged on the main body of the toilet bowl, and the pressing assembly 20 and the flushing valve 10 are arranged at different positions. Therefore, it is unnecessary to disassemble the water tank when the pressing assembly 20 is to be repaired or replaced. The flushing valve 10 may be the original flushing component of a toilet bowl, and the pressing assembly 20 is added on that basis. Thus, a combination of two flushing switches can be realized by retrofitting an existing toilet bowl. That approach is easy to use widely and applicable to a variety of scenarios.

[0020] In the present disclosure, unless otherwise specified, the orientational terms “top”, “bottom”, “left”, and “right” usually refer to top, bottom, left and right indicated in corresponding drawings. “Inside”and “outside”refer to the inside and outside of the contour of the corresponding part.

[0021] Some embodiments of the present application will be detailed below with reference to the accompanying drawings. It may be understood that the embodiments described herein are only provided to describe and explain the present application, but are not intended to constitute any limitation on the present application.

[0022] Please see FIGS. 1 to 3. The present disclosure provides a flushing device, which comprises: a flushing valve 10 comprising a valve body 11 and a driving component 12, wherein the valve body 11 is arranged to be able to open under a driving action of the driving component 12; a pressing assembly 20 comprising a first housing 21, a first button 22, a first rocker 23 and a pull rope 241, wherein the first button 22 is movably arranged with respect to the first housing 21 and abuts against one end of the first rocker 23, the first rocker 23 is rotatably arranged with respect to the first housing 21, the other end of the first rocker 23 is connected to the pull rope 241, the pull rope 241 is connected to the valve body 11, and the first rocker 23 is arranged to be able to pull the pull rope 241 under the driving action of the first button 22, so as to drive the valve body 11 to open via the pull rope 241.

[0023] In this embodiment, the flushing valve 10 is provided with a driving component 12 as a flushing switch, and the valve body 11 can be driven to open by the driving component 12 for water flushing; the driving component 12 can be used as a hand-operated switch to facilitate the user to flush with water by pressing the switch by hand. The pressing assembly 20 may be used as a foot-operated switch to press the first button 22, the first button 22 pushes the first rocker 23 to rotate, the first rocker 23 pulls the pull rope 241, and the pull rope 241 drives the valve body 11 to open for water flushing, which is convenient for the user to flush with water by kicking the pressing assembly by foot. In addition, when either of the flushing switches fails, the other flushing switch can be used to accomplish timely flushing, which is to say, when the driving component 12 fails, the pressing assembly 20 can be used for flushing; and when the pressing assembly 20 fails, the driving component 12 can be used for flushing, so as to avoid an inconvenient situation.

[0024] Specifically, the center of rotation of the first rocker 23 is located between its two ends, wherein one end of the first rocker 23 abuts against the first button 22, and the other end of the first rocker 23 is connected to the pull rope 241, so that the stress direction of one end of the first rocker 23 is opposite to the movement direction of the other end, i.e., when the first button 22 is moved in a direction toward the first rocker 23, the first rocker 23 can be pushed to rotate around its center of rotation, while the pull rope 241 is pulled in a direction toward the first button 22.

[0025] Please see FIGS. 1 to 3. In some embodiments, the first button 22 comprises a button body 221 and an abutting block 222. An inclined plane is formed on the abutting block 222 at the end of the button body 221 facing the first rocker 23, the first rocker 23 is obliquely arranged in an initial state, and the inclination angle and direction of the first rocker 23 in this state are the same as those of the inclined plane, respectively.

[0026] In this embodiment, the first button 22 pushes the first rocker 23 to move by directly contacting with the first rocker 23, and there is no transmission component between them. Thus, on one hand, the structure of the pressing assembly 20 is compact, and the number of parts is reduced; on the other hand, after the first button 22 is moved, the power can be quickly transmitted to the first rocker 23, and the power of the first button 22 is prevented from being consumed by a transmission component between the first button 22 and the first rocker 23, for example, the power of the first button 22 may be consumed by the friction of the transmission component. Thus, the force required for pressing the first button 22 can be reduced.

[0027] Specifically, as described in the orientation shown in FIG. 2, the left lower part of the first rocker 23 is configured into a cambered surface, and the inclined surface of the abutting block 222 is tangent to the cambered surface. Thus, on one hand, the rotation torque of the first rocker 23 is high, and the first rocker 23 can be easily driven to rotate with small force, and the operation is labor-saving; on the other hand, the contact surface between the abutting block 222 and the first rocker 23 is small, thereby the friction between them is small, and the resistance encountered when the abutting block 222 pushes the first rocker 23 to rotate is small, and the first rocker 23 can rotate more smoothly. Continuing with the description in the orientation shown in FIG. 2, the abutting block 222 is a wedge-shaped block, and has a rounded tip formed at the right end. In the initial state, the first rocker 23 is arranged obliquely to the left from top to bottom, and the inclined plane of the abutting block 222 is also arranged obliquely to the left from top to bottom. When the button body 221 is subjected to acting force from left to right, the abutting block 222 is moved from left to right, so that it pushes the lower end of the first rocker 23 to move; the left lower part of the first rocker 23 is moved along the inclined plane of the abutting block 222 first, and the first rocker 23 rotates counterclockwise with respect to its center of rotation; when the first rocker 23 rotates to an extent that the rounded tip of the abutting block 222 abuts against the first rocker 23, the left lower part of the first rocker 23 is disengaged from the inclined plane of the abutting block 222, and the rounded tip of the abutting block 222 continues pushing the first rocker 23 to rotate counterclockwise, and the first rocker 23 pulls the pull rope 241 to move from right to left. With the arrangement of the inclined plane of the abutting block 222, on one hand, a high torque is provided for the rotation of the first rocker 23; on the other hand, when the rounded tip of the abutting block 222 abuts against the first rocker 23, the abutting block 222 pushes the first rocker 23 to rotate counterclockwise faster around its point of abutment against the first rocker 23.

[0028] Continuing with the description in the orientation shown in FIG. 2, in the initial state, the left end of the button body 221 protrudes from the left end of the first housing 21, thereby the user can press the button body 221 conveniently.

[0029] Please see FIGS. 1 to 3. In some embodiments, the pressing assembly 20 further comprises a first elastic member 25 and / or a second elastic member 26. The first elastic member 25 is connected to or abuts against the first housing 21 and the first button 22, the first button 22 can be reset under the elastic force of the first elastic member 25, the second elastic member 26 is connected to the first rocker 23 and abuts against or is connected to the first housing 21, and the first rocker 23 can be reset under the elastic force of the second elastic member 26.

[0030] In this embodiment, when force is applied to the first button 22, the first elastic member 25 is compressed; when the force applied to the first button 22 disappears, the first elastic member 25 is restored to its original length by its own elastic force, thus, it drives the first button 22 to reset. As described in the orientation shown in FIG. 2, the direction of the force applied to the first button 22 is to the right, and the direction of movement of the first button 22 in the resetting process is to the left. The first elastic member 25 can reset the first button 22 by means of the elastic force, so as to avoid a problem that the first button 22 can't be pressed again after being pressed because it can't be reset to its original position. When the first button 22 is subjected to acting force, it transfers the acting force to the first rocker 23, so that the first rocker 23 rotates, and the second elastic member 26 is elastically deformed; when the acting force on the first button 22 disappears, the second elastic member 26 is restored by its own elastic force, and it drives the first rocker 23 to reset. As described in the orientation shown in FIG. 2, the direction of rotation of the first rocker 23 under the acting force of the first button 22 is counterclockwise, while the direction of rotation of the first rocker 23 in the resetting process is clockwise. The second elastic member 26 can reset the first rocker 23 by means of the elastic force. When the first button 22 is pressed next time, the first button 22 can push the first rocker 23 to rotate again, so as to avoid that the first rocker 23 can't be pushed to rotate by pressing the first button 22 again.

[0031] Specifically, the first elastic member 25 may be a spring, and the abutting block 222 is located in the first elastic member 25.

[0036] In this embodiment, when the pull rope 241 is moved under the action of the first rocker 23, the bushing 242 ensures that the pull rope 241 can be moved only inside the bushing 242. The mounting fitting 27 is used to mount the bushing 242 to the first housing 21 to prevent the bushing 242 from being moved owing to the movement of the pull rope 241.

[0037] Specifically, the mounting fitting 27 comprises a nut 271 and a C-shaped ferrule 272, wherein the nut 271 is fitted around a part of the bushing 242, the pull rope 241 can be moved with respect to the bushing 242, and the mounting fitting 27 is connected to an inner wall of the mounting hole and fixes the bushing 242 to the first housing 21.

The extension tube 211 and the first housing 21 are integrally formed, and the inner wall of the extension tube 211 is composed of two sections, the first section is an equal-diameter inner wall, and the second section is an inclined inner wall, the equal-diameter inner wall and the inclined inner wall are sequentially arranged in a direction toward the mounting hole. The bushing 242 is fitted around the pull rope 241; the mounting fitting 27 comprises a nut 271 and a C-shaped ferrule 272, wherein the nut 271 is hollow inside, the bushing 242 is inserted through the nut 271, and the first section of the inner wall of the extension tube 211 is threaded for threaded connection with the nut 271; the C-shaped ferrule 272 has a notch and is fitted around the bushing 242, the C-shaped ferrule 272 is located in the extension tube 211 and has a frustum-shaped structure; the nut 271 pushes the C-shaped ferrule 272 into the second section of the extension tube 211, and the frustum-shaped structure of the C-shaped ferrule 272 is fitted with the inclined inner wall of the second section of the extension tube 211; under the pressure of the nut 271, the C-shaped ferrule 272 holds the bushing 242 firmly, so as to fix the bushing 242 to the extension tube 211. The bushing 242 may be made of rubber.

[0038] Please see FIGS. 1 to 3. In some embodiments, the valve body 11 comprises a second housing 111, a flushing cover 112 and a transmission component 113, wherein a bottom end of the second housing 111 has an opening, the flushing cover 112 is arranged on the opening, the transmission component 113 is connected to the flushing cover 112 and the pull rope 241 and is drivingly fitted with the driving component 12, and the transmission component 113 is arranged to be able to move the flushing cover 112 for water flushing under the driving action of the driving component 12 or the pull rope 241.

[0039] In this embodiment, both the driving component 12 and the pressing assembly 20 can drive the flushing cover 112 to move via the transmission member 113 for water flushing.

[0040] Specifically, a second cavity is formed inside the second housing 111, and the transmission member 113 is located in the second cavity. The driving component 12 comprises a second button, a third button, a third elastic member and a fourth elastic member, wherein the second button and the third button are arranged side by side, and both of them are in sliding fit with the inner wall of the second housing 111, the second button is connected to the inner wall of the second housing 111 via the third elastic member, and the third button is connected to the inner wall of the second housing 111 via the fourth elastic member. When the second button is pressed, the second button is moved into the second cavity, and, at the same time, the third elastic member is compressed and pushes the transmission member 113 for transmission to drive the flushing cover 112 to move for water flushing; when the force applied to the second button disappears, the third elastic member is restored by its own elastic force to drive the second button to reset; when the third button is pressed, the third button is moved into the second cavity, and, at the same time, the fourth elastic member is compressed and pushes the transmission member 113 for transmission to drive the flushing cover 112 to move for water flushing; when the force applied to the third button disappears, the fourth elastic member is restored by its own elastic force to drive the third button to reset. The length of the third button extending into the second cavity is greater than the length of the fourth button extending into the second cavity, and the amount of flushing water discharged when the third button is pressed is greater than the amount of flushing water discharged when the second button is pressed, so that high-water flushing and low-water flushing are realized with the two buttons respectively. As described in the orientation shown in FIG. 3, the direction of the force exerted on the first button and the second button is downward, and the direction of the movement of the first button and the second button in the resetting process is upward.

Thus, the reparation is convenient and quick.

[0049] Please see FIGS. 1 to 3. In some embodiments, the connector 28 comprises a connecting sleeve 281 fitted around the first housing 21 and a protrusion 282 arranged on the periphery of the connecting sleeve 281, and the protrusion 282 is arranged to be elastically deformed so that it can be snapped into a hole formed in the main body of the toilet bowl by elastic force.

[0050] In this embodiment, when the pressing assembly 20 is forced to enter the hole in the main body of the toilet bowl, the protrusion 282 is elastically deformed by a squeezing action of the inner wall of the hole. When the force applied to the pressing assembly 20 disappears, the protrusion 282 abuts against the inner wall of the hole firmly owing to its elastic property, so that it is snap-fitted with the hole to mount the pressing assembly 20 to the main body of the toilet bowl; to detach the pressing assembly 20 from the main body of the toilet bowl, the pressing assembly 20 can be pulled out of the hole by means of the elastic deformation of the protrusion 282 without disassembling the main body of the toilet bowl. Thus, the operation is convenient, and the reparation is convenient and quick.

[0051] Specifically, the connecting sleeve 281 and the protrusion 282 are formed into an integral structure. The protrusion 282 protrudes in the radial direction of the connecting sleeve 281 and extends in the circumferential direction of the connecting sleeve 281. The protrusion 282 may be an arc section formed by a plurality of segments spaced apart from each other at an interval. Alternatively, the protrusion 282 may be a C-shaped structure, or an annular structure. The diameter of the protrusion 282 is greater than the inner diameter of the hole in the toilet bowl body, so that the protrusion 282 can be firmly fitted with the inner wall of the hole. As described in the orientation shown in FIG. 2, the first housing 21 is divided into two sections, namely, a first horizontal section and a first vertical section, wherein the first horizontal section is a cylindrical structure, while the first vertical section is a circular plate structure, and the two sections are coaxial with and perpendicular to each other; the connecting sleeve 281 is also divided into two sections, namely, a second horizontal section and a second vertical section, wherein the second horizontal section is a cylindrical structure, while the second vertical section is a circular plate structure, and the two sections are coaxial with and perpendicular to each other; the first horizontal section of the first housing 21 is parallel to the first horizontal section of the connecting sleeve 281, and the first horizontal section of the connecting sleeve 281 is fitted around and attached to the first horizontal section of the first housing 21; the first vertical section of the first housing 21 is parallel to the first vertical section of the connecting sleeve 281, and the first vertical section of the connecting sleeve 281 is attached to the first vertical section of the first housing 21; both the outer diameter of the first vertical section of the first housing 21 and the outer diameter of the first vertical section of the connecting sleeve 281 are greater than the diameter of the hole in the main body of the toilet bowl. When the protrusion 282 is snapped into the inner wall of the hole, both the first vertical section of the first housing 21 and the first vertical section of the connecting sleeve 281 are located outside the hole, and the first vertical section of the connecting sleeve 281 can be attached to the peripheral end of the hole; with such an arrangement, on one hand, to remove the pressing assembly 20, the pressing assembly 20 can be pulled out of the hole by exerting force on the first vertical section of the first housing 21 and the first vertical section of the connecting sleeve 281, which is to say, the pressing assembly 20 can be removed conveniently; on the other hand, the button body 221 of the first button 22 can be exposed outside the hole, so that the user can use it conveniently. In the present application, both the driving component 12 and the pressing assembly 20 drive the valve body 11 to open in a non-powered driving approach without any electrical control component, and the valve body 11 is opened by means of mechanical transmission. Thus, the structure of the flushing device is simpler and more compact, and will not be damaged easily.

[0052] In the present application, the pressing assembly 20 and the driving component 12 are two separate flushing switches that do not interfere with each other, and there is no linkage between them. When the first button 22 of the pressing assembly 20 is pressed with force, the pull rope 241 pulls the pull rod 1132 for flushing, and the driving component 12 will not move in linkage; when the driving component 12 is pressed with force, the driving component 12 pushes down the second rocker 1131 to drive the pull rod 1132 for flushing, and the first button 22 of the pressing assembly 20 will not move in linkage. Therefore, the two flushing switches, i.e., the pressing assembly 20 and the driving component 12, are used independently from each other. When either flushing switch is damaged, the normal use of the other flushing switch will not be affected, which is to say, the two flushing switches will not be damaged at the same time owing to the interaction between them, and the flushing device has a simple structure and high reliability.

[0053] The present disclosure further provides a toilet bowl, which comprises a main body and the flushing device described above, wherein the flushing device is arranged on the main body.

[0054] In this embodiment, the flushing device of the toilet bowl has all the technical schemes and technical effects of the flushing device described above, and will not be further detailed here.

[0055] Specifically, the toilet bowl further comprises a water tank, a flushing valve 10 is arranged in the water tank, a pressing assembly 20 is detachably arranged on the main body of the toilet bowl, and the pressing assembly 20 and the flushing valve 10 are arranged at different positions. Therefore, it is unnecessary to disassemble the water tank when the pressing assembly 20 is to be repaired or replaced. The flushing valve 10 may be the original flushing component of a toilet bowl, and the pressing assembly 20 is added on that basis. Thus, a combination of two flushing switches can be realized by retrofitting an existing toilet bowl. That approach is easy to use widely and applicable to a variety of scenarios.
