Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, specifically to a flushing switching device and a toilet. Background Technology

[0002] Toilet flushing involves direct connection of tap water to the toilet's auxiliary flush and the urinal flush, controlled by devices such as a reversing valve. However, the reversing valves in these technologies either rely on motors or have complex structures, resulting in low stability, reliability, and cost-effectiveness, as well as slow reversing speeds. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a flushing switching device and a toilet.

[0004] The flushing switching device of this utility model embodiment includes:

[0005] The housing has a first cavity, a first inlet, a first outlet, and a second outlet. The first inlet, the first outlet, and the second outlet are all in communication with the first cavity. The first inlet is used to introduce liquid into the first cavity, and the first outlet is located above the second outlet.

[0006] A movable frame is movably disposed within the first cavity such that the movable frame can move from a first position to a second position, the second position being above the first position. In the first position, the movable frame can cover at least a portion of the second outlet, and in the second position, the movable frame can cover at least a portion of the first outlet. Liquid introduced into the first cavity through the first inlet can impact the movable frame to drive it upward.

[0007] A limiting member is located within the first cavity. The limiting member is used to limit the movement of the frame. The limiting member cooperates with the housing to restrict the movement of the frame to the first position.

[0008] Therefore, the flushing switching device according to the embodiments of this utility model has the advantages of simple structure and high durability.

[0009] In some embodiments, when the liquid introduced into the first cavity continuously impacts the movable frame located at the first position, the limiting member cooperates with the housing to restrict the movable frame to the first position;

[0010] When the limiting member releases its restriction on the movable frame, the liquid introduced into the first cavity can drive the movable frame to move upward to the second position and restrict the movable frame to the second position;

[0011] After the liquid flow into the first cavity is stopped, the movable frame located in the second position falls.

[0012] In some embodiments, at least a portion of the limiting member is movable relative to the movable frame;

[0013] The movable frame has a third position within the first cavity, which is located below the first position. In the initial state, the movable frame is located in the third position. After the liquid is stopped flowing into the first cavity, the movable frame, which is located in the second position, falls to the third position.

[0014] In some embodiments, the limiting member is connected to the movable frame, and a slot is provided in the first cavity. When at least a portion of the limiting member extends into the slot, it can restrict the movable frame located at the first position from moving upward. After the limiting member extends out of the slot, it can release the restriction on the movable frame.

[0015] When the liquid introduced into the first cavity causes the movable frame located at the third position to move upward so that the movable frame causes the limiting member to move upward, at least a portion of the limiting member extends into the slot.

[0016] After the liquid is stopped flowing into the first cavity, the movable frame located at the first position can move downward and the limiting member extends out of the slot. When the liquid is flowed into the first cavity again after a first preset time, the liquid flowing into the first cavity can drive the movable frame to move upward to the second position and restrict the movable frame at the second position.

[0017] In some embodiments, the opening of the card slot faces the limiting member in a first direction, and the first direction is perpendicular to the vertical direction;

[0018] The limiting member includes a limiting body and a protrusion. The limiting body is movably disposed on the movable frame. The protrusion is located between the limiting body and the slot in the first direction, and the protrusion can extend into the slot.

[0019] The limiting member has a second preset buoyancy. When at least a portion of the limiting member moves upward relative to the moving frame using the buoyancy, the protrusion moves in the first direction away from the slot.

[0020] The slot has a third preset size in the vertical direction. During the process of the moving frame driving the limiting member to move from the third position to the first position, the protrusion moves upward in the slot.

[0021] The slot has a downward-facing limiting surface, and when the top surface of the protrusion abuts against the limiting surface, it can restrict the upward movement of the movable frame located in the first position.

[0022] In some embodiments, the limiting member is slidably connected to the movable frame.

[0023] In some embodiments, the movable frame has a first slide rail extending along a second direction, the second direction forming an angle with the first direction and the up-down direction, and the distance between the first slide rail and the slot in the first direction increases upward.

[0024] The limiting body is slidably disposed in the first slide rail along the second direction. When the limiting body floats upward relative to the moving frame in the first slide rail, the protrusion moves in the first direction away from the slot.

[0025] In some embodiments, the angle between the second direction and the horizontal plane is greater than or equal to 70° and less than or equal to 80°.

[0026] In some embodiments, the limiting member is rotatably connected to the movable frame, and the extension direction of the rotation axis of the limiting member is a third direction, any two of the third direction, the first direction, and the up and down direction are perpendicular to each other.

[0027] In some embodiments, the lower part of the limiting body on the side away from the slot in the first direction is rotatably connected to the movable frame;

[0028] The upper part of the limiting body on the side facing the slot in the first direction is connected to the protrusion;

[0029] When the limiting body rotates upward relative to the moving frame using buoyancy, the protrusion moves in the first direction away from the slot.

[0030] In some embodiments, the first inlet is located at the bottom of the first cavity, the first outlet is located at the top of the first cavity, the second outlet is located at the side of the first cavity, and the second outlet faces the movable frame in the first direction;

[0031] The movable frame includes a first plate, a second plate, and a third plate. The thickness directions of the first plate and the second plate are both vertical. The first plate is located at the bottom of the movable frame, and liquid entering the first cavity can impact the bottom surface of the first plate. The second plate is located at the top of the movable frame, and the second plate of the movable frame at the second position can cover the first outlet. The thickness direction of the third plate is the first direction, and the third plate is located on the side of the movable frame adjacent to the second outlet in the first direction. During the process of the movable frame moving from the third position to the first position, the third plate covers the second outlet.

[0032] In some embodiments, the movable frame is movably disposed within the first cavity in the vertical direction.

[0033] In some embodiments, the first cavity is provided with a guide groove extending in the vertical direction, and the movable frame is provided with a guide post extending into the guide groove;

[0034] The movable frame is spaced apart from the wall of the first cavity on the side away from the second outlet in the first direction;

[0066] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0067] The flushing switching device of this utility model according to embodiments is described below with reference to the accompanying drawings. Figures 1 to 14 As shown, the flushing switching device according to an embodiment of the present invention includes a housing 1, a movable frame 2, and a limiting member 3.

[0068] The housing 1 has a first cavity 11, a first inlet 12, a first outlet 13, and a second outlet 14. The first inlet 12, the first outlet 13, and the second outlet 14 are all connected to the first cavity 11. The first inlet 12 is used to introduce liquid into the first cavity 11. The liquid in the first cavity 11 can be discharged from the first outlet 13 and the second outlet 14. The first outlet 13 is located above the second outlet 14.

[0069] The movable frame 2 is movably disposed within the first cavity 11 such that it can move from a first position to a second position, the second position being above the first position. In the first position, the movable frame 2 can cover at least a portion of the second outlet 14, thereby allowing the discharge volume of the first outlet 13 to be greater than that of the second outlet 14. In the second position, the movable frame 2 can cover at least a portion of the first outlet 13, thereby allowing the discharge volume of the second outlet 14 to be greater than that of the first outlet 13. That is, the first position is below the second position, and the movable frame 2 can move upward from the first position to the second position. Movement refers to any type of change of an object from one position to another, regardless of whether its trajectory is a straight line, a curve, or a composite path. Movement can be sliding (translation), rotation (rotation), or a combination of both. That is, movement includes sliding and rotation.

[0070] The first inlet 12 faces upward and is located below the movable frame 2. The liquid introduced into the first cavity 11 through the first inlet 12 impacts the movable frame 2, causing it to move upward. Thus, when liquid is introduced into the first cavity 11 through the first inlet 12, the thrust (impact force) of the liquid pushes the movable frame 2 upward from the first position, thereby moving it to the second position.

[0071] The limiting member 3 is located within the first cavity 11. The limiting member 3 is used to limit the movement of the movable frame 2. The limiting member 3, in conjunction with the housing 1, can restrict the movement of the movable frame 2 in the vertical direction, so that the movable frame 2 can stop at a preset position after rising. The limiting member 3 can be a locking member or a telescopic member. For example, the limiting member 3 is a telescopic rod, which allows the movable frame 2 to stop at the first position.

[0072] The flushing switching device according to this embodiment of the present invention uses a movable frame 2 installed within a first cavity 11. Liquid introduced into the first cavity 11 through a first inlet 12 impacts the movable frame 2, causing it to rise to a second position. The movable frame 2 then falls back down due to its own gravity. Compared to using a reversing valve or a motor, the flushing switching device according to this embodiment of the present invention utilizes the impact force of the liquid introduced through the first inlet 2 and the gravity of the movable frame 2 to drive its rise and fall. This results in a simple structure and high durability for the flushing switching device according to this embodiment of the present invention.

[0073] Therefore, the flushing switching device according to the embodiments of this utility model has the advantages of simple structure and high durability.

[0074] In some embodiments, when the liquid introduced into the first cavity 11 continuously impacts the movable frame 2 located at the first position, the limiting member 3 cooperates with the housing 1 to restrict the movable frame 2 to the first position. Specifically, the liquid introduced into the first cavity 11 through the first inlet 12 can impact the movable frame 2 to drive it upward. When the movable frame 2 is in the first position, the limiting member 3 can restrict the movable frame 2 to the first position. This allows the movable frame 2 to cover at least a portion of the second outlet 14, thereby making the discharge volume of the first outlet 13 greater than the discharge volume of the second outlet 14, thus facilitating the discharge of liquid from the first cavity 11 from the first outlet 13.

[0075] When the limiting member 3 releases its restriction on the movable frame 2, the liquid entering the first cavity 11 can move the movable frame 2 upward to the second position and restrict the movable frame 2 to the second position. Specifically, when the limiting member 3 does not restrict the movable frame 2, the liquid entering the first cavity 11 through the first inlet 12 can impact the movable frame 2 to move it to the second position, and the continuous impact of the liquid can restrict the movable frame 2 to the second position. This allows the movable frame 2 to cover at least a portion of the first outlet 13, thereby making the discharge volume of the second outlet 14 greater than that of the first outlet 13, thus facilitating the discharge of liquid from the first cavity 11 from the second outlet 14.

[0076] After the liquid supply to the first cavity 11 is stopped, the movable frame 2, which is located in the second position, falls. Specifically, when the liquid supply is stopped (the water source is turned off), the liquid in the first cavity 11 can be discharged from the second outlet 14, so that the movable frame 2 can fall back (to the initial position) by its own gravity.

[0077] In some embodiments, at least a portion of the limiting member 3 is movable relative to the movable frame 2. The movable frame 2 has a third position within the first cavity 11, located below the first position. In the initial state (to the initial position), the movable frame 2 is located in the third position. After the liquid flow into the first cavity 11 stops, the movable frame 2, which is in the second position, falls to the third position. Specifically, the movable frame 2 can move upwards from the third position to the first and second positions sequentially. When the movable frame 2 moves between the third and first positions, it can cover at least a portion of the second outlet 14. In the initial state (to the initial position), the liquid flowing into the first cavity 11 through the first inlet 12 can impact the movable frame 2, thereby causing the movable frame 2 to move upwards from the third position to the first position. When the movable frame 2 rises to the first position, the limiting member 3 engages with the housing 1 to restrict the movable frame 2 to the first position. This allows the movable frame 2 to cover at least a portion of the second outlet 14, resulting in a greater discharge volume from the first outlet 13 than from the second outlet 14, thus facilitating the discharge of liquid from the first cavity 11 from the first outlet 13.

[0078] like Figures 1 to 10 As shown, in some embodiments, housing 1 includes a first housing 17 and a second housing 18.

[0079] The opening of the first housing 17 faces downwards. The first housing 17 has a second cavity 171, a third cavity 172, and a fourth cavity 173. The second cavity 171 is connected to the first cavity 11 through a first outlet 13. The second cavity 171, the third cavity 172, and the fourth cavity 173 are sequentially connected. The second cavity 171, the third cavity 172, and the fourth cavity 173 are all cylindrical cavities, and the diameters of the third cavity 172, the second cavity 171, and the fourth cavity 173 increase sequentially. That is, the liquid in the first cavity 11 can be discharged from the housing 1 through the first outlet 13, the second cavity 171, the third cavity 172, and the fourth cavity 173 in sequence.

[0080] The opening of the second housing 18 faces upward, and the second housing 18 and the first housing 17 define the first cavity 11. The second housing 18 and the first housing 17 are connected by a snap fastener 181, and a sealing ring 182 is provided between the second housing 18 and the first housing 17. The first inlet 12 and the second outlet 14 are opened on the second housing 18.

[0081] Specifically, the inner and outer circumferential contours (generally) of the first housing 17 and the second housing 18 in the vertical direction are rectangular. Buckles 181 are located on the top of the four side plates of the second housing 18, and the bottom of the four side plates of the first housing 17 are provided with latching protrusions that respectively mate with the four buckles 181. A portion of the first housing 17 can extend into the second housing 18, and a sealing ring 182 is located between the first housing 17 and the second housing 18 in the inward and outward directions to improve the sealing performance of the first cavity 11.

[0082] like Figures 1 to 10 As shown, in some embodiments, the first inlet 12 is located at the bottom of the first cavity 11 (second housing 18), the first outlet 13 is located at the top of the first cavity 11 (first housing 17), and the second outlet 14 is located on the side of the first cavity 11 (second housing 18). The second outlet 14 faces the movable frame 2 in a first direction. Specifically, the first inlet 12 faces upward, and the first inlet 12 and the first outlet 13 are opposite each other. The downward-facing end face of the first outlet 13 is horizontal. The first direction is perpendicular to the vertical direction, and the first direction can be the horizontal direction, as shown by the arrows in the figure. For example, the second outlet 14 faces left and is located on the right side of the housing 1.

[0083] like Figure 13 and Figure 14 As shown, in some embodiments, the flushing switching device further includes a pump body 5, which is connected to the first inlet 12 via a water inlet pipe 51. The pump body 5 is used to control the flow of liquid into the first cavity 11 through the first inlet 12. That is, the flow of liquid into the first cavity 11 can be controlled by starting the pump body 5. For example, the pump body 5 is a water pump.

[0084] like Figures 1 to 10 As shown, in some embodiments, the movable frame 2 is movably disposed within the first cavity 11 in the vertical direction. Specifically, the first cavity 11 is provided with a guide groove 16 extending in the vertical direction, and the movable frame 2 is provided with a guide post 26 extending into the guide groove 16. The movable frame 2 is provided with guide posts 26 on both sides in the third direction, and the guide posts 26 extend in the vertical direction. The first cavity 11 is provided with guide grooves 16 on two opposite walls in the third direction, and the two guide posts 26 are respectively movably disposed within the two guide grooves 16 in the vertical direction. Any two of the third direction, the first direction, and the vertical direction are perpendicular to each other. The third direction can be the front-back direction. For example, the movable frame 2 is provided with guide posts 26 on both sides in the front-back direction.

[0085] like Figures 1 to 10 As shown, in some embodiments, the movable frame 2 includes a first plate 21, a second plate 22, and a third plate 23.

[0086] The thickness directions of the first plate 21 and the second plate 22 are both vertical. The first plate 21 is located at the bottom of the movable frame 2, and the liquid entering the first cavity 11 can impact the bottom surface of the first plate 21. The second plate 22 is located at the top of the movable frame 2, and the second plate 22 in the second position of the movable frame 2 can cover the first outlet 13.

[0087] The thickness direction of the third plate 23 is the first direction. The third plate 23 is located on the side of the movable frame 2 adjacent to the second outlet 14 in the first direction. During the movement of the movable frame 2 from the third position to the first position, the third plate 23 can seal the second outlet 14. Specifically, the movable frame 2 has a cavity and an opening communicating with the first cavity 11. The second outlet 14 is located at the lower part of the housing 1 (second housing 18). For example, the thickness direction of the third plate 23 is the left-right direction, the third plate 23 is located on the right side of the movable frame 2, and the second outlet 14 is located at the lower part of the right side of the housing 1 (second housing 18).

[0088] like Figures 1 to 10 As shown, in some embodiments, the movable frame 2 is spaced apart from the wall of the first cavity 11 on the side away from the second outlet 14 in a first direction. This facilitates the passage of liquid through this gap and its discharge from the first outlet 13. For example, the left side of the movable frame 2 is spaced apart from the wall of the first cavity 11.

[0089] In some embodiments, the bottom surface of the third plate 23 is located below the bottom surface of the first plate 21. Specifically, a portion of the third plate 23 is located below the first plate 21, thereby allowing the first plate 21 and the first inlet 12 (bottom surface of the first cavity 11) to have a predetermined size in the third position, so that liquid can be discharged from the first outlet 13 after impacting the first plate 21.

[0090] In some embodiments, a sealing gasket 34 is provided on the top of the second plate 22. When the movable frame 2 reaches the second position, the sealing gasket 34 seals the first outlet 13. Specifically, the sealing gasket 34 is annular, and a fixing member on the top of the second plate 22 passes through the sealing gasket 34 and fixes the sealing gasket 34 to the top of the second plate 22. This allows the top surface of the sealing gasket 34 to abut against the first outlet 13, thereby sealing the first outlet 13. For example, the sealing gasket 34 is made of an elastic material.

[0091] like Figures 6 to 10 As shown, in some embodiments, the movable frame 2 is equipped with a counterweight 4. This allows the movable frame 2 to descend quickly when there is no liquid impacting the first plate 21, thereby improving the flushing switching speed.

[0092] like Figures 1 to 11 As shown, in some embodiments, a slot 15 is provided within the first cavity 11. The slot 15 has a third preset size in the vertical direction, and the opening of the slot 15 faces the limiting member 3 in the first direction. Specifically, the first housing 17 and the second housing 18 define the slot 15. For example, the opening of the slot 15 faces to the left.

[0093] The limiting member 3 is connected to the movable frame 2. When at least a part of the limiting member 3 extends into the slot 15, it can restrict the movable frame 2 located in the first position from moving upward. After the limiting member 3 extends out of the slot 15, it can release the restriction on the movable frame 2.

[0094] In some embodiments, the limiting member 3 includes a limiting body 31 and a protrusion 32. The limiting body 31 is movably disposed on the movable frame 2, and the protrusion 32 is located between the limiting body 31 and the slot 15 in a first direction, and the protrusion 32 can extend into the slot 15. Specifically, the protrusion 32 is located on the side of the limiting body 31 adjacent to the slot 15, so that the limiting body 31 can be engaged in the slot 15 by the protrusion 32. For example, the protrusion 32 is located on the right side of the limiting body 31. The limiting body 31 is a cavity, and the bottom of the limiting body 31 is open, allowing liquid to enter the limiting body 31.

[0095] The limiting member 3 has a second preset buoyancy. When at least a portion of the limiting member 3 moves upward relative to the moving frame 2 using the buoyancy, the protrusion 32 moves in a direction away from the slot 15 in a first direction. Specifically, the second preset buoyancy of the limiting member 3 is greater than the weight of the limiting member 3. This allows the limiting member 3 to move relative to the moving frame 2 using the buoyancy when liquid is present in the first cavity 11. Furthermore, when the limiting member 3 moves relative to the moving frame 2, the movement of the protrusion 32 in the first direction away from the slot 15 allows the limiting member 3 to disengage from the slot 15, so that the limiting member 3 no longer limits the moving frame 2.

[0096] In some embodiments, the slot 15 has a limiting surface facing downwards, and when the top surface of the protrusion 32 abuts against the limiting surface, it can restrict the upward movement of the movable frame 2 located in the first position.

[0097] During the process of the movable frame 2 moving the limiting member 3 from the third position to the first position, the protrusion 32 moves upward within the slot 15. Specifically, when the liquid impacts the movable frame 2 and causes it to rise, the movable frame 2 can move the limiting member 3 upward and limit its movement in the first direction; that is, at this moment, the limiting member 3 does not rise using buoyancy. This allows the limiting member 3 to be positioned within the slot 15, thus facilitating its limitation of the movable frame 2 in the first position.

[0098] like Figures 1 to 5 and Figure 12As shown, in some embodiments, the limiting member 3 is slidably connected to the movable frame 2. Specifically, the movable frame 2 has a first slide 24 extending along a second direction, which forms an angle with the first direction and the vertical direction. The distance between the first slide 24 and the slot 15 in the first direction increases upward. The second direction is perpendicular to the third direction. The top of the first slide 24 is open, and the bottom of the first slide 24 is closed. The first slide 24 is inclined upward and in the first direction away from the slot 15. For example, the first slide 24 is inclined upward and to the left.

[0099] In some embodiments, the angle between the second direction and the horizontal plane is greater than or equal to 70° and less than or equal to 80°. That is, the angle between the extension direction of the first slide 24 and the horizontal plane is greater than or equal to 70° and less than or equal to 80°. For example, the angle between the first slide 24 and the horizontal plane is 75°.

[0100] The limiting body 31 is slidably disposed within the first slide rail 24 in a second direction. When the limiting body 31 floats upward relative to the movable frame 2 within the first slide rail 24, the protrusion 32 moves in the first direction away from the slot 15. For example, the movable frame 2 has a second slide rail 25. The dimension of the second slide rail 25 in a third direction (front-back direction) is smaller than the dimension of the first slide rail 24 in a third direction (front-back direction), and the protrusion 32 is slidably located within the second slide rail 25. When the limiting body 31 floats upward relative to the movable frame 2 within the first slide rail 24, the protrusion 32 moves to the left. The second slide rail 25 is an opening of the first slide rail 24.

[0101] like Figure 2 and Figure 3 As shown, when the liquid entering the first cavity 11 moves the movable frame 2, located in the third position, upward so that the movable frame 2 moves the limiting member 3 upward, at least a portion of the limiting member 3 extends into the slot 15. Specifically, when the movable frame 2 moves upward and moves the limiting member 3 upward, the bottom of the first slide 24 abuts against the bottom of the limiting body 31, that is, the limiting member 3 does not move relative to the movable frame 2, and the limiting member 3 does not disengage from the slot 15. Thus, when the movable frame 2 moves upward to the first position, the limiting member 3 is located in the slot 15, and the protrusion 32 abuts against the limiting surface of the slot 15. This allows the limiting member 3 to restrict the upward movement of the movable frame 2, and at this moment, the liquid continuously impacts the first plate 21 of the movable frame 2, so that the movable frame 2 can remain in the first position under the impact force of the liquid and the restriction of the limiting member 3, thereby allowing the liquid to be discharged from the first outlet 13.

[0102] like Figure 4 and Figure 5As shown, after the liquid flow into the first cavity 11 stops, the movable frame 2, located in the first position, can move downwards and the limiting member 3 extends out of the slot 15. When liquid is flowed into the first cavity 11 again after a first preset time, the liquid flowing into the first cavity 11 can drive the movable frame 2 upwards to the second position and restrict the movable frame 2 to the second position. Specifically, the weight of the movable frame 2 is greater than its buoyancy. After the liquid flow into the first cavity 11 stops, the movable frame 2 moves downwards under its own weight, causing the limiting member 3 to move downwards so that the limiting member 3 disengages from the slot 15. Since there is liquid in the first cavity 11, the limiting member 3 can float upwards within the first slide 24 using its own buoyancy. That is, at this moment, the limiting member 3 floats upwards relative to the movable frame 2 to move away from the slot 15 in the first direction (the limiting member 3 can be located above the slot 15). After the first preset time, when liquid is introduced into the first cavity 11 again, the liquid introduced into the first cavity 11 can impact and drive the moving frame 2 to move upward. At this time, the limiting member 3 located outside the slot 15 does not restrict the moving frame 2 (there is already a certain amount of water in the first cavity 11, and under the action of buoyancy, the limiting member 3 will not move downward with the moving frame 2 when the water is stopped, and its position is higher than the slot 15, so the limiting member 3 will no longer function when water is introduced again). This allows the moving frame 2 to continue to move upward to the second position, so that when the liquid is discharged from the second outlet 14, it can continuously impact the first plate 21 of the moving frame 2, so as to restrict the moving frame 2 to the second position.

[0103] like Figures 6 to 10 As shown, in some embodiments, the limiting member 3 is rotatably connected to the movable frame 2, and the extension direction of the rotation axis of the limiting member 3 is the third direction. Specifically, the limiting body 31 is located inside the movable frame 2, and the top of the third plate 23 of the movable frame 2 has a mating groove that can lock the protrusion 32. The top of the third plate 23 of the movable frame can be used to restrict the downward movement (rotation) of the protrusion 32. The lower part of the limiting body 31 on the side away from the slot 15 in the first direction (via the first rotating shaft 33) is rotatably connected to the movable frame 2. The upper part of the limiting body 31 on the side facing the slot 15 in the first direction is connected to the protrusion 32. When the limiting body 31 and the protrusion 32 rotate upward relative to the movable frame 2 by buoyancy, the protrusion 32 moves in the first direction away from the slot 15.

[0104] For example, the rotation axis of the first rotating shaft 33 of the limiting member 3 extends in the front-to-back direction. The movable frame 2 is provided with a counterweight 4 (counterweight column) adjacent to the rotating shaft of the limiting member 3. The lower left side of the limiting body 31 (via the rotating shaft) is rotatably connected to the movable frame 2. The upper right side of the limiting body 31 is connected to the protrusion 32. When the limiting body 31 and the protrusion 32 rotate upward relative to the movable frame 2 using buoyancy, the protrusion 32 moves to the left.

[0105] like Figure 7 and Figure 8 As shown, when the liquid entering the first cavity 11 moves the movable frame 2, located in the third position, upward so that the movable frame 2 moves the limiting member 3 upward, at least a portion of the limiting member 3 extends into the slot 15. Specifically, when the movable frame 2 moves upward and moves the limiting member 3 upward, the limiting member 3 is located inside the movable frame 2, and the top of the third plate 23 abuts against the bottom of the protrusion 32, that is, the limiting member 3 does not move relative to the movable frame 2, and the limiting member 3 does not disengage from the slot 15. Thus, when the movable frame 2 moves upward to the first position, the limiting member 3 is located inside the slot 15, and the protrusion 32 abuts against the limiting surface of the slot 15. This allows the limiting member 3 to restrict the upward movement of the movable frame 2, and at this moment, the liquid continuously impacts the first plate 21 of the movable frame 2, so that the movable frame 2 can remain in the first position under the impact force of the liquid and the restriction of the limiting member 3, thereby allowing the liquid to be discharged from the first outlet 13.

[0106] like Figure 9 and Figure 10 As shown, after the liquid flow into the first cavity 11 stops, the movable frame 2, located in the first position, can move downwards and the limiting member 3 extends out of the slot 15. When liquid is flowed into the first cavity 11 again after a first preset time, the liquid flowing into the first cavity 11 can drive the movable frame 2 upwards to the second position and restrict the movable frame 2 to the second position. Specifically, after the liquid flow into the first cavity 11 stops, the movable frame 2 moves downwards under its own weight. At this time, there is liquid in the first cavity 11, which allows the limiting member 3 to rotate upwards relative to the movable frame 2 using its own buoyancy. That is, at this time, the limiting member 3 floats upwards relative to the movable frame 2 as it moves downwards with the movable frame 2, and disengages from the slot 15 in the first direction. After the first preset time, when liquid is introduced into the first cavity 11 again, the liquid introduced into the first cavity 11 can impact and drive the movable frame 2 to move upward. At this time, the limiting member 3 located outside the slot 15 does not restrict the movable frame 2, so that the movable frame 2 can continue to move upward to the second position, so that when the liquid is discharged from the second outlet 14, it can continuously impact the first plate 21 of the movable frame 2, so as to restrict the movable frame 2 to the second position.

[0107] like Figure 13 and Figure 14 As shown, the present invention also proposes a toilet, which includes a flushing switching device, a water tank 6 and a toilet body 61 according to an embodiment of the present invention.

[0108] The first inlet 12 of the housing 1 of the flushing switching device (via the pump body 5) is connected to the water tank 6, the first outlet 13 of the flushing switching device is connected to the front flush port 62 of the toilet body 61, and the second outlet 14 of the flushing switching device is connected to the auxiliary flush port 63 of the toilet body 61.

[0109] Therefore, the toilet according to the present invention has the advantages of simple structure and high durability.

[0110] This utility model also proposes a control method for a flushing switching device according to an embodiment of this utility model. The control method for the flushing switching device according to an embodiment of this utility model includes the following steps:

[0111] In the initial state, the movable frame 2 is located in the third position of the first cavity 11 of the housing 1 (e.g., Figure 2 and Figure 7 (As shown).

[0112] Liquid is introduced into the first cavity 11 through the first inlet 12. The liquid can impact the movable frame 2 located in the third position and drive the movable frame 2 to move upward. The limiting member 3 can restrict the upward moving movable frame 2 to the first position so that the liquid flow rate discharged from the first outlet 13 in the first cavity 11 is greater than the liquid flow rate discharged from the second outlet 14.

[0113] Specifically, the pump body 5 is activated to allow liquid to be introduced into the first cavity 11 through the inlet pipe 51 and the first inlet 12. For example... Figure 3 and Figure 8 As shown, the liquid applies a thrust (F) to the moving frame 2. 水 The movable frame 2 is moved upward to the first position. During the process of the movable frame 2 rising to the first position, the limiting member 3 is driven and the limiting member 3 is located in the slot 15. Thus, the limiting member 3 can limit the movable frame 2 at the first position so that the liquid flow rate discharged from the first outlet 13 in the first cavity 11 is greater than the liquid flow rate discharged from the second outlet 14.

[0114] After the liquid flow into the first cavity 11 is stopped, the movable frame 2, located at the first position, can move downwards and the limiting member 3 extends out of the slot 15. When liquid is flowed into the first cavity 11 again after a first preset time, the liquid flowing into the first cavity 11 can drive the movable frame 2 upwards to the second position and restrict the movable frame 2 to the second position, so that the liquid flow rate discharged from the first outlet 13 in the first cavity 11 is less than the liquid flow rate discharged from the second outlet 14. Specifically, as shown in the figure... Figure 4 , Figure 5 , Figure 9 and Figure 10As shown. After the liquid flow into the first cavity 11 stops, the movable frame 2 moves downward under its own weight. At this time, there is liquid in the first cavity 11, which allows the limiting member 3 to move upward relative to the movable frame 2 by its own buoyancy (rotation or sliding). That is, at this time, the limiting member 3 floats upward relative to the movable frame 2 and disengages from the slot 15 in the first direction. After a first preset time, when liquid is flowed into the first cavity 11 again, the liquid flowing into the first cavity 11 can impact and drive the movable frame 2 to move upward. At this time, the limiting member 3 located outside the slot 15 does not restrict the movable frame 2, so that the movable frame 2 can continue to move upward to the second position, so that when the liquid is discharged from the second outlet 14, it can continuously impact the first plate 21 of the movable frame 2, so as to limit the movable frame 2 to the second position.

[0115] After the liquid flow into the first inlet 12 stops, the movable frame 2, which was in the second position, falls to the third position. The liquid in the first cavity 11 can either be discharged from the second outlet 14 or fall back into the first inlet 12. The limiting member 3 also re-enters the slot 15. Thus, one motion cycle is completed.
