[0069] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0070] The flushing switching device according to the embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1 to 14 As shown, the flushing switching device according to the embodiment of the present invention includes a housing 1 , a moving frame 2 and a limiting member 3 .

[0071] 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 pass liquid into the first cavity 11, and the liquid in the first cavity 11 can be discharged from the first outlet 13 and the second outlet 14, and the first outlet 13 is located above the second outlet 14.

[0072] The movable frame 2 is movably disposed in the first cavity 11, and the movable frame 2 can sequentially move upward from the first position to the second position and the third position. In the first position and the second position, the movable frame 2 can cover at least part of the second outlet 14, so that the discharge amount of the first outlet 13 can be greater than the discharge amount of the second outlet 14. In the third position, the movable frame 2 can cover at least part of the first outlet 13, so that the discharge amount of the second outlet 14 can be greater than the discharge amount of the first outlet 13. That is, the first position is located below the second position, and the second position is located below the third position. The movable frame 2 can sequentially move upward to the second position and the third position, and when the movable frame 2 moves between the first position and the second position, it can cover at least part of the second outlet 14.

[0073] The first inlet 12 faces upward, and the first inlet 12 is located below the movable frame 2. The first inlet 12 faces the movable frame 2, and the liquid introduced into the first cavity 11 through the first inlet 12 can impact the movable frame 2 so as to drive the movable frame 2 to move upward. Therefore, when the liquid is introduced into the first cavity 11 through the first inlet 12, the thrust (impact force) of the liquid can push the movable frame 2 upward from the first position, so that the movable frame 2 can be moved to the second position and the third position.

[0074] The limiting member 3 is located in the first cavity 11, and at least a portion of the limiting member 3 can move relative to the moving frame 2. The limiting member 3 is used to limit the moving frame 2. Specifically, the limiting member 3 can limit the moving frame 2 in the up and down directions so that the moving frame 2 can stop at a preset position after rising. The limiting member 3 can be a snap-fit ​​member or a telescopic member. For example, the limiting member 3 is a telescopic rod, and the limiting member 3 can stop the moving frame 2 at the second position.

[0075] When the liquid introduced into the first cavity 11 drives the mobile rack 2 located at the first position to move upward and continuously impacts the mobile rack 2, the stopper 3 can limit the mobile rack 2 to the second position. Specifically, when the mobile rack 2 is located at the first position, the liquid introduced into the first cavity 11 through the first inlet 12 can impact the mobile rack 2 so as to drive the mobile rack 2 to move upward. When the mobile rack 2 rises to the second position, the stopper 3 can limit the mobile rack 2 to the second position. So that the mobile rack 2 can cover at least part of the second outlet 14, so that the discharge amount of the first outlet 13 is greater than the discharge amount of the second outlet 14, thereby facilitating the discharge of the liquid in the first cavity 11 from the first outlet 13.

[0076] The liquid introduced into the first cavity 11 can drive the movable frame 2 to move upward to the third position and restrict the movable frame 2 to the third position. Specifically, when the limiter 3 does not restrict the movable frame 2, the liquid introduced into the first cavity 11 through the first inlet 12 can impact the movable frame 2 so as to move the movable frame 2 to the third position, and the continuous impact of the liquid can restrict the movable frame 2 to the third position. So that the movable frame 2 can cover at least part of the first outlet 13, so that the discharge amount of the second outlet 14 can be greater than the discharge amount of the first outlet 13, thereby facilitating the discharge of the liquid in the first cavity 11 from the second outlet 14.

[0077] After the liquid is stopped from being introduced into the first cavity 11, the movable rack 2 located at the third position falls to the first position. Specifically, when the liquid 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 rack 2 can fall back to the first position (initial position) by its own gravity.

[0078] The flushing switching device according to the embodiment of the present invention is provided with a mobile frame 2 in the first cavity 11, and can use the liquid introduced into the first cavity 11 through the first inlet 12 to impact the mobile frame 2, so as to drive the mobile frame 2 to rise to the second position or the third position, and the mobile frame 2 can fall back to the first position by its own gravity. Compared with the reversing valve or the motor, the flushing switching device according to the embodiment of the present invention uses the impact force of the liquid introduced into the first inlet 2 and the gravity of the mobile frame 2 to drive the mobile frame 2 to rise and fall. This makes the flushing switching device according to the embodiment of the present invention simple in structure and strong in durability.

[0079] Therefore, the flushing switching device according to the embodiment of the present invention has the advantages of simple structure and high durability.

[0080] like Figures 1 to 10 As shown, in some embodiments, the housing 1 includes a first housing 17 and a second housing 18 .

[0081] The opening of the first shell 17 faces downward, and the first shell 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 the first outlet 13, and the second cavity 171, the third cavity 172, and the fourth cavity 173 are connected in sequence. 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 in sequence. That is, the liquid in the first cavity 11 can be discharged from the shell 1 through the first outlet 13, the second cavity 171, the third cavity 172, and the fourth cavity 173 in sequence.

[0082] The opening of the second shell 18 faces upward, and the second shell 18 and the first shell 17 define a first cavity 11. The second shell 18 is connected to the first shell 17 by a buckle 181, and a sealing ring 182 is provided between the second shell 18 and the first shell 17. The first inlet 12 and the second outlet 14 are provided on the second shell 18.

[0083] Specifically, the inner and outer contours of the cross-sections of the first shell 17 and the second shell 18 in the up-down direction are (substantially) rectangular. The buckles 181 are provided at the tops of the four side panels of the second shell 18, and the bottoms of the four side panels of the first shell 17 are provided with convex portions respectively matched with the four buckles 181. A portion of the first shell 17 can extend into the second shell 18, and the sealing ring 182 is located between the first shell 17 and the second shell 18 in the inward and outward directions, so as to improve the sealing performance of the first cavity 11.

[0084] 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 shell 18), the first outlet 13 is located at the top of the first cavity 11 (first shell 17), and the second outlet 14 is located at the side of the first cavity 11 (second shell 18), and the second outlet 14 is facing the mobile frame 2 in the first direction. Specifically, the first inlet 12 faces the upper side, the first inlet 12 and the first outlet 13 are arranged opposite to each other, and the end surface of the first outlet 13 facing the lower side is a horizontal plane. The first direction is perpendicular to the up-down direction, and the first direction can be the left-right direction, and the up-down direction and the left-right direction are shown by the arrows in the figure. For example, the second outlet 14 faces the left side, and the second outlet 14 is opened on the right side of the shell 1.

[0085] like Fig.13 and Fig.14 As shown, in some embodiments, the flushing switching device further includes a pump body 5, which is connected to the first inlet 12 through a water inlet pipe 51, and the pump body 5 is used to control the liquid to pass into the first cavity 11 through the first inlet 12. That is, the pump body 5 can be started to control the liquid to pass into the first cavity 11 through the first inlet 12. For example, the pump body 5 is a water pump.

[0086] like Figures 1 to 10As shown, in some embodiments, the mobile frame 2 is movably arranged in the first cavity 11 along the up-down direction. Specifically, a guide groove 16 extending in the up-down direction is provided in the first cavity 11, and a guide column 26 extending into the guide groove 16 is provided on the mobile frame 2. The mobile frame 2 is provided with guide columns 26 on both sides in the third direction, and the guide columns 26 extend in the up-down direction. The first cavity 11 is provided with guide grooves 16 on two opposite wall surfaces in the third direction, and two guide columns 26 are movably arranged in the two guide grooves 16 in the up-down direction respectively. Any two of the third direction, the first direction and the up-down direction are perpendicular to each other. The third direction can be a front-to-back direction. For example, the mobile frame 2 is provided with guide columns 26 on both sides in the front-to-back direction.

[0087] like Figures 1 to 10 As shown, in some embodiments, the mobile frame 2 includes a first plate body 21 , a second plate body 22 and a third plate body 23 .

[0088] The thickness directions of the first plate body 21 and the second plate body 22 are both in the up-down direction. The first plate body 21 is located at the bottom of the moving frame 2, and the liquid entering the first cavity 11 can impact the bottom surface of the first plate body 21. The second plate body 22 is located at the top of the moving frame 2, and the second plate body 22 of the moving frame 2 located at the third position can cover the first outlet 13.

[0089] The thickness direction of the third plate 23 is the first direction. The third plate 23 is located on the side of the mobile frame 2 adjacent to the second outlet 14 in the first direction. When the mobile frame 2 moves from the first position to the second position, the third plate 23 covers the second outlet 14. Specifically, the mobile frame 2 has a cavity and an opening connected to the air. The second outlet 14 is located at the lower part of the housing 1 (the 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 mobile frame 2, and the second outlet 14 is located at the lower part of the right side of the housing 1 (the second housing 18).

[0090] like Figures 1 to 10 As shown, in some embodiments, the side of the mobile rack 2 away from the second outlet 14 in the first direction is spaced apart from the wall of the first cavity 11. This facilitates the liquid to pass through the space and be discharged from the first outlet 13. For example, the left side of the mobile rack 2 is spaced apart from the wall of the first cavity 11.

[0091] In some embodiments, the bottom surface of the third plate body 23 is located below the bottom surface of the first plate body 21. Specifically, a portion of the third plate body 23 is located below the first plate body 21, so that in the first position, the first plate body 21 and the first inlet 12 (the bottom surface of the first cavity 11) have a preset size, so that the liquid is discharged from the first outlet 13 after impacting the first plate body 21.

[0092] In some embodiments, a sealing gasket 34 is provided on the top of the second plate body 22, and when the movable frame 2 reaches the first position, the sealing gasket 34 covers the first outlet 13. Specifically, the sealing gasket 34 is annular, and the fixing member on the top of the second plate body 22 passes through the sealing gasket 34 and fixes the sealing gasket 34 on the top of the second plate body 22. So that the top surface of the sealing gasket 34 can abut against the first outlet 13, thereby covering the first outlet 13. For example, the sealing gasket 34 is made of elastic material.

[0093] like Figures 6 to 10 As shown, in some embodiments, a counterweight 4 is provided on the mobile frame 2. Thus, when there is no liquid impacting the first plate 21 of the mobile frame 2, the mobile frame 2 can be quickly lowered, thereby increasing the flushing switching speed.

[0094] like Figures 1 to 11 As shown, in some embodiments, a card slot 15 is provided in the first cavity 11, the card slot 15 has a third preset size in the up and down direction, and the opening of the card slot 15 is oriented toward the stopper 3 in the first direction. Specifically, the first shell 17 and the second shell 18 define the card slot 15. For example, the opening of the card slot 15 is oriented toward the left side.

[0095] The limiting member 3 is connected to the moving frame 2 . When at least a portion of the limiting member 3 extends into the slot 15 , the moving frame 2 located at the second position can be restricted from moving upward. When the limiting member 3 extends out of the slot 15 , the limiting of the moving frame 2 can be released.

[0096] 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, the protrusion 32 is located between the limiting body 31 and the card slot 15 in the first direction, and the protrusion 32 can extend into the card slot 15. Specifically, the protrusion 32 is located on a side of the limiting body 31 adjacent to the card slot 15, so that the limiting body 31 can be engaged in the card slot 15 through the protrusion 32. For example, the protrusion 32 is disposed 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, and liquid can flow into the limiting body 31.

[0097] The stopper 3 has a second preset buoyancy, and when at least part of the stopper 3 moves upward relative to the mobile frame 2 by using the buoyancy, the protrusion 32 moves in the first direction away from the slot 15. Specifically, the second preset buoyancy of the stopper 3 is greater than the gravity of the stopper 3. Thus, when there is liquid in the first cavity 11, the stopper 3 can move relative to the mobile frame 2 by using the buoyancy, and when the stopper 3 moves relative to the mobile frame 2, the protrusion 32 moves in the first direction away from the slot 15, so that the stopper 3 is no longer limited to the mobile frame 2.

[0098] In some embodiments, the slot 15 has a limiting surface facing downward, and when the top surface of the protrusion 32 abuts against the limiting surface, the movable frame 2 located at the second position can be restricted from moving upward.

[0099] In the process that the moving frame 2 drives the limiting member 3 to move from the first position to the second position, the protrusion 32 moves upward in the slot 15. Specifically, when the liquid impacts the moving frame 2 and drives the moving frame 2 to rise, the moving frame 2 can drive the limiting member 3 to move upward and limit the limiting member 3 in the first direction, that is, at this moment, the limiting member 3 does not rise by buoyancy. So that the limiting member 3 can be located in the slot 15, so that it is convenient for the limiting member 3 to limit the moving frame 2 located in the second position.

[0100] like Figures 1 to 5 and Fig.12 As shown, in some embodiments, the stopper 3 is slidably connected to the mobile frame 2. Specifically, the mobile frame 2 has a first slide 24, the first slide 24 extends along the second direction, the second direction is at an angle with the first direction and the up-down direction, and the distance between the first slide 24 and the card 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 tilted upward and in the first direction away from the card slot 15. For example, the first slide 24 is tilted upward and leftward.

[0101] 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 slideway 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 slideway 24 and the horizontal plane is 75°.

[0102] The limiting body 31 is slidably disposed in the first slideway 24 along the second direction. When the limiting body 31 floats upward relative to the moving frame 2 in the first slideway 24, the protrusion 32 moves in the first direction away from the slot 15. For example, the moving frame 2 has a second slideway 25. The size of the second slideway 25 in the third direction (front-rear direction) is smaller than the size of the first slideway 24 in the third direction (front-rear direction), and the protrusion 32 is slidably located in the second slideway 25. When the limiting body 31 floats upward relative to the moving frame 2 in the first slideway 24, the protrusion 32 moves to the left.

[0103] like Figure 2 and Figure 3As shown, the liquid introduced into the first cavity 11 drives the mobile frame 2 located at the first position to move upward so that when the mobile frame 2 drives the stopper 3 to move upward, at least part of the stopper 3 extends into the card slot 15. Specifically, when the mobile frame 2 moves upward and drives the stopper 3 to move upward, the bottom of the first slideway 24 abuts against the bottom of the stopper body 31, that is, the stopper 3 does not move relative to the mobile frame 2, and the stopper 3 does not separate from the card slot 15. Therefore, when the mobile frame 2 moves upward to the second position, the stopper 3 is located in the card slot 15, and the protrusion 32 abuts against the stopper surface of the card slot 15. So that the stopper 3 limits the upward movement of the mobile frame 2, and at this moment, the liquid continues to impact the first plate 21 of the mobile frame 2, so that the mobile frame 2 can stay in the second position under the impact force of the liquid and the limitation of the stopper 3, and then the liquid can be discharged from the first outlet 13.

[0104] like Figure 4 and Figure 5 As shown, after the liquid is stopped from being introduced into the first cavity 11, the movable frame 2 located at the second position can move downward and the stopper 3 extends out of the card slot 15. When the liquid is introduced into the first cavity 11 again after the first preset time, the liquid introduced into the first cavity 11 can drive the movable frame 2 to move upward to the third position and limit the movable frame 2 to the third position. Specifically, after the liquid is stopped from being introduced into the first cavity 11, the movable frame 2 moves downward under its own gravity. At this moment, there is liquid in the first cavity 11, so that the stopper 3 can float upward in the first slide 24 by its own buoyancy. That is, at this moment, the stopper 3 floats upward relative to the movable frame 2 and is separated from the card 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 moment, the limit member 3 located outside the card slot 15 does not restrict the movable frame 2, so that the movable frame 2 can continue to move upward to the third position, so that the liquid can continue to impact the first plate 21 of the movable frame 2 when being discharged from the second outlet 14, so as to limit the movable frame 2 to the third position.

[0105] like Figures 6 to 10 As shown, in some embodiments, the limit member 3 is rotatably connected to the mobile frame 2, and the extension direction of the rotation axis of the limit member 3 is the third direction. Specifically, the limit body 31 is located in the mobile frame 2, and the top of the third plate 23 of the mobile frame can be used to limit the downward movement (rotation) of the protrusion 32. The limit body 31 is rotatably connected to the mobile frame 2 (through the first rotating shaft 33) at the lower part of the side away from the card slot 15 in the first direction. The limit body 31 is connected to the protrusion 32 at the upper part of the side facing the card slot 15 in the first direction. When the limit body 31 and the protrusion 32 rotate upward relative to the mobile frame 2 using buoyancy, the protrusion 32 moves in the first direction in the direction away from the card slot 15.

[0106] For example, the extension direction of the rotation axis of the first rotating shaft 33 of the limiting member 3 is the front-to-back direction. The moving frame 2 is provided with a counterweight 4 (counterweight column) adjacent to the rotating shaft of the limiting member 3. The lower portion of the left side of the limiting body 31 is rotationally connected to the moving frame 2 (through the rotating shaft). The upper portion of the 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 moving frame 2 using buoyancy, the protrusion 32 moves to the left.

[0107] like Figure 7 and Figure 8 As shown, the liquid introduced into the first cavity 11 drives the mobile frame 2 located at the first position to move upward so that when the mobile frame 2 drives the stopper 3 to move upward, at least part of the stopper 3 extends into the card slot 15. Specifically, when the mobile frame 2 moves upward and drives the stopper 3 to move upward, the stopper 3 is located in the mobile frame 2, and the top of the third plate 23 abuts against the bottom of the protrusion 32, that is, the stopper 3 does not move relative to the mobile frame 2, and the stopper 3 does not separate from the card slot 15. Therefore, when the mobile frame 2 moves upward to the second position, the stopper 3 is located in the card slot 15, and the protrusion 32 abuts against the limit surface of the card slot 15. So that the stopper 3 limits the upward movement of the mobile frame 2, and at this moment, the liquid continues to impact the first plate 21 of the mobile frame 2, so that the mobile frame 2 can stay in the second position under the impact force of the liquid and the limitation of the stopper 3, and then the liquid can be discharged from the first outlet 13.

[0108] like Fig. 9 and Fig.10 As shown, after the liquid is stopped from being introduced into the first cavity 11, the movable frame 2 located at the second position can move downward and the stopper 3 extends out of the card slot 15. When the liquid is introduced into the first cavity 11 again after the first preset time, the liquid introduced into the first cavity 11 can drive the movable frame 2 to move upward to the third position and restrict the movable frame 2 to the third position. Specifically, after the liquid is stopped from being introduced into the first cavity 11, the movable frame 2 moves downward under its own gravity. At this moment, there is liquid in the first cavity 11, so that the stopper 3 can rotate upward relative to the movable frame 2 by using its own buoyancy. That is, at this moment, the stopper 3 floats upward relative to the movable frame 2 and is separated from the card 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 moment, the limit member 3 located outside the card slot 15 does not restrict the movable frame 2, so that the movable frame 2 can continue to move upward to the third position, so that the liquid can continue to impact the first plate 21 of the movable frame 2 when being discharged from the second outlet 14, so as to limit the movable frame 2 to the third position.

[0109] like Fig.13 and Fig.14As shown, the present invention further proposes a toilet. The toilet according to an embodiment of the present invention includes a flushing switching device according to an embodiment of the present invention, a water tank 6 and a toilet body 61.

[0110] The first inlet 12 of the housing 1 of the flushing switching device is connected to the water tank 6 (through the pump body 5), the first outlet 13 of the flushing switching device is connected to the face flushing port 62 of the toilet body 61, and the second outlet 14 of the flushing switching device is connected to the auxiliary flushing port 63 of the toilet body 61.

[0111] Therefore, the toilet according to the embodiment of the present invention has the advantages of simple structure and high durability.

[0112] The present invention further proposes a control method for a flushing switching device according to an embodiment of the present invention. The control method for a flushing switching device according to an embodiment of the present invention comprises the following steps:

[0113] In the initial state, the mobile frame 2 is located at the first position of the first cavity 11 of the housing 1 (eg Figure 2 and Figure 7 shown).

[0114] Liquid is introduced into the first cavity 11 through the first inlet 12, and the liquid can impact the movable rack 2 located at the first position and drive the movable rack 2 to move upward. The limit member 3 can limit the movable rack 2 moving upward to the second position, so that the liquid flow discharged from the first outlet 13 in the first cavity 11 is greater than the liquid flow discharged from the second outlet 14.

[0115] Specifically, the pump body 5 is started to allow liquid to flow into the first cavity 11 through the water inlet pipe 51 and the first inlet 12. Figure 3 and Figure 8 As shown, the liquid exerts a thrust (F 水 ), the movable rack 2 moves upward to the second position, and in the process of the movable rack 2 rising to the second position, the limiting member 3 is driven, and the limiting member 3 is located in the card slot 15, so that the limiting member 3 can limit the movable rack 2 in the second position, so that the liquid flow discharged from the first outlet 13 in the first cavity 11 is greater than the liquid flow discharged from the second outlet 14.

[0116] After the liquid is stopped from being introduced into the first cavity 11, the movable frame 2 located at the second position can move downward and the stopper 3 extends out of the card slot 15. When the liquid is introduced into the first cavity 11 again after the first preset time, the liquid introduced into the first cavity 11 can drive the movable frame 2 to move upward to the third position and limit the movable frame 2 to the third 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, Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown. After the liquid is stopped from being introduced into the first cavity 11, the mobile frame 2 moves downward under its own gravity. At this moment, there is liquid in the first cavity 11, so that the limiter 3 can use its own buoyancy to move upward (rotate or slide) relative to the mobile frame 2. That is, at this moment, the limiter 3 floats upward relative to the mobile 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 mobile frame 2 to move upward. At this moment, the limiter 3 located outside the slot 15 does not restrict the mobile frame 2, so that the mobile frame 2 can continuously move upward to the third position, so that the liquid can continue to impact the first plate 21 of the mobile frame 2 when it is discharged from the second outlet 14, so as to limit the mobile frame 2 to the third position.

[0117] After the liquid is stopped from entering the first inlet 12, the movable frame 2 located at the third position falls to the first position. The liquid in the first cavity 11 can be discharged from the second outlet 14 or fall back into the first inlet 12. The stopper 3 also goes deep into the slot 15 again. Thus, one movement cycle is completed.
