[0052] The 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 cannot be understood as limiting the present invention.

[0053] The flushing switching device of the present utility model embodiment is described below with reference to the accompanying drawings. Figures 1 to 13 As shown, the flushing switching device according to the embodiment of the utility model includes a housing 1 and a buoy 2 .

[0054] The housing 1 has a first cavity 11, a first inlet 12, a first outlet 13 and a second outlet 14, and 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. The first outlet 13 is located above the second outlet 14, and the first inlet 12 is located below the second outlet 14. A card slot 15 and a sliding slot 16 are provided in the housing 1, and the sliding slot 16 extends in the up-down direction.

[0055] A buckle 21 is provided at the top of the buoy 2, an eccentric shaft 22 is provided at the bottom of the buoy 2, a counterweight is provided on the eccentric shaft 22, and the eccentric shaft 22 is movably provided in the sliding groove 16 so that the buoy 2 can rotate in the first cavity 11 and can move in the first cavity 11 in the up and down directions. The buoy 2 can use the liquid (buoyancy) in the first cavity 11 to drive the buckle 21 to rotate in the horizontal direction in the direction adjacent to the eccentric shaft 22, and the buoy 2 can use its gravity to drive the buckle 21 to rotate in the horizontal direction in the direction away from the eccentric shaft. Specifically, the buoy 2 has a preset buoyancy, and the buoy 2 can rotate around the axis of the eccentric shaft 22. The buoyancy of the buoy 2 is greater than the gravity of the buoy 2, and the sum of the buoyancy of the buoy 2, the eccentric shaft 22 and the counterweight is less than the sum of the gravity of the buoy 2, the eccentric shaft 22 and the counterweight. That is to say, when there is liquid in the first cavity 11 and the first inlet 12 does not flow into the liquid (i.e., when the liquid does not impact the float 2), the eccentric shaft 22 and the counterweight can drive the float 2 to fall in the water. The float 2 can use the buoyancy (under the cover of the liquid in the first cavity 11) to rotate around the axis of the eccentric shaft 22, and drive the buckle 21 to rotate in the horizontal direction in the direction adjacent to the eccentric shaft 22, so that the buckle 21 is separated from or extends into the slot 15. When there is no liquid in the first cavity 11, the float 2 uses its own gravity to rotate around the axis of the eccentric shaft 22, and drives the buckle 21 to rotate in the horizontal direction in the direction away from the eccentric shaft, so that the buckle 21 is separated from or extends into the slot 15.

[0056] The float 2 can move upward from the first position to the second position. In the first position, the float 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 second position, the float 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. The liquid entering the first cavity 11 through the first inlet 12 can impact the float 2 so as to drive the float 2 to move upward. Specifically, the float 2 is located above the first inlet 12, and the liquid entering the first cavity 11 from the first inlet 12 can directly impact the float 2 so as to drive the float 2 to move upward. Therefore, when liquid is introduced into the first cavity 11 through the first inlet 12, the thrust (impact force) of the liquid can push the float 2 (as well as the eccentric shaft 22 and the counterweight) from the first position to the second position, thereby moving the float 2 to the second position, that is, the impact force of the liquid entering the first cavity 11 can be used to drive the movable part 2 to move from the first position to the second position.

[0057] The buckle 21 located in the slot 15 can limit the buoy 2 to the first position, and the slot 15 has a first preset size in the up and down direction. Specifically, the buckle 21 cooperates with the slot 15, and after the buckle 21 extends into the slot 15 and contacts the top surface of the slot, the slot 15 can limit the buoy 2 from moving upward to the second position. After the buckle 21 extends out of the slot 15, the slot 15 can release the limit on the buoy 2.

[0058] The flushing switching device according to the embodiment of the utility model utilizes the liquid introduced into the first cavity 11 through the first inlet 12 to impact the float 2, so as to drive the float 2 located at the first position to move upward to the second position. When no liquid is introduced into the first inlet 12, the eccentric rotating shaft 22 and the counterweight can drive the float 2 to move downward to the first position, so that the float 2 can seal the first outlet 13 and the second outlet 14 respectively.

[0059] When no liquid is introduced into the first inlet 12 and there is liquid in the first cavity 11, the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the horizontal direction along the direction adjacent to the eccentric shaft 22, thereby changing the matching relationship between the buckle 21 and the slot 15 (the buckle 21 is separated from or extends into the slot 15); when no liquid is introduced into the first inlet 12 and there is no (or less) liquid in the first cavity 11, the float 2 can use its gravity to drive the buckle 21 to rotate in the horizontal direction along the direction away from the eccentric shaft. Thereby changing the matching relationship between the buckle 21 and the slot 15 (the buckle 21 is separated from or extends into the slot 15). The buckle 21 located in the slot 15 can limit the float 2 in the first position, so that when the buckle 21 is located in the slot 15, when the liquid introduced into the first cavity 11 through the first inlet 12 impacts the float 2 located in the first position, the float 2 does not move upward. That is, the gravity and buoyancy of the float 2, the eccentric shaft 22 and the counterweight, as well as the matching relationship between the buckle 21 and the slot 15, are used to respectively achieve the effect of sealing the first outlet 13 and the second outlet 14. Compared with the reversing valve or the motor, the flushing switching device according to the embodiment of the utility model uses the impact force of the liquid entering the first inlet 12 and the buoyancy of the float 2 to drive the float 2 to rise, and the gravity of the float 2, the eccentric shaft 22 and the counterweight drives the float 2 to fall. The buckle 21 can be used to limit the float 2, so that the flushing switching device according to the embodiment of the utility model has a simple structure and strong durability.

[0060] Therefore, the flushing switching device according to the embodiment of the utility model has the advantages of simple structure and high durability.

[0061] In some embodiments, the flushing switching device further includes a pump body, which is connected to the first inlet 12 through a water inlet pipe, and the pump body is used to control the liquid to pass into the first cavity 11 through the first inlet 12. That is, the pump body can be started to control the liquid to pass into the first cavity 11 through the first inlet 12. For example, the pump body is a water pump.

[0062] like Figures 1 to 13 As shown, in some embodiments, the housing 1 includes a first housing 17 and a second housing 18 .

[0063] The opening of the first shell 17 faces downward, and the first outlet 13 is provided on the first shell 17. The opening of the second shell 18 faces upward, and the second shell 18 and the first shell 17 define a first cavity 11, and the second shell 18 and the first shell 17 are connected by a clamping portion, and a sealing ring 19 is provided between the second shell 18 and the first shell 17, and the first inlet 12 is provided at the bottom of the second shell 18, and the second outlet 14 is provided on the side of the second shell 18, and the first inlet 12 is located (directly) below the buoy 2.

[0064] Specifically, the clamping part is provided at the bottom of the side plate of the first shell 17, and the top of the side plate of the second shell 18 is provided with clamping holes respectively matched with the clamping parts. A part of the first shell 17 can extend into the second shell 18, and the sealing ring 19 is located between the first shell 17 and the second shell 18 in the inner and outer directions to improve the sealing of the first cavity 11. The first outlet 13 is opened at the top of the first shell 17.

[0065] like Figures 1 to 13 As shown, in some embodiments, the opening of the slot 15 faces the float 2 in the first direction, and the buckle 21 is located at one end of the float 2 facing the slot 15 in the first direction. When there is liquid in the first cavity 11 and the first inlet 12 is not filled with water, the float 2 can use the liquid (buoyancy) in the first cavity 11 to drive the buckle 21 to rotate in the first direction in the direction adjacent to the eccentric shaft 22. When there is no liquid (or less liquid) in the first cavity 11 and the first inlet 12 is not filled with water, the float 2 can use its gravity to drive the buckle 21 to rotate in the first direction in the direction away from the eccentric shaft 22. The eccentric shaft 22 is located at the end of the float 2 in the first direction, and the extension direction of the eccentric shaft 22 is the second direction, and any two of the first direction, the second direction and the up-down direction are perpendicular. The first direction can be the left-right direction, and the second direction can be the front-back direction, and the left-right direction, the front-back direction and the up-down direction are shown by the arrows in the figure.

[0066] For example, the card slot 15 is located on the right side of the float 2, the opening of the card slot 15 faces the left side, the buckle 21 is located at the upper part of the right end of the float 2, and the eccentric shaft 22 is located at the end in the left-right direction of the bottom of the float 2. The extension direction of the eccentric shaft 22 is the front-to-back direction. When there is liquid in the first cavity 11 and the first inlet 12 is not filled with water, the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the left-right direction in the direction adjacent to the eccentric shaft 22. When there is no liquid in the first cavity 11 (or when there is less liquid) and the first inlet 12 is not filled with water, the float 2 can use its gravity to drive the buckle 21 to rotate in the left-right direction in the direction away from the eccentric shaft 22.

[0067] like Figure 2 and Figure 8 As mentioned above, in some embodiments, the buoy 2 has a first through hole 27 penetrating therethrough along the second direction, and the eccentric shaft 22 is disposed in the first through hole 27. Specifically, the buoy 2 can rotate relative to the eccentric shaft 22. The counterweight can be integrally formed with the eccentric shaft 22, or the counterweight can be hung on the eccentric shaft 22. In this way, the counterweight and the eccentric shaft 22 can drive the cylinder 2 to fall.

[0068] In some embodiments, the slot 15 and the second outlet 14 are located on the same side of the first cavity 11 in the first direction. The second outlet 14 is located below the slot 15. For example, the slot 15 and the second outlet 14 are located on the right side of the first cavity 11.

[0069] In some embodiments, the buoy 2 has a first side surface 23 and a second side surface 24 facing away from each other in the first direction, wherein the first side surface 23 faces the second outlet 14 in the first direction, and the second side surface 24 faces away from the card slot 15 in the first direction. For example, the first side surface 23 faces the right side, and the second side surface 24 faces the left side.

[0070] In some embodiments, a limiting groove 28 is provided in the housing 1, which is directed toward the buoy 2 in the first direction, and the limiting groove 28 extends in the up-down direction. A limiting block 25 is provided on the upper part of the second side surface 24, and the limiting block 25 has a third preset size in the first direction. The limiting block 25 is movably provided in the limiting groove 28 in the up-down direction. Specifically, the limiting block 25 is located in the limiting groove 28, so that the limiting groove 28 limits the limiting block 25, thereby limiting the buoy 2 in the second direction. The limiting block 25 is located on the side of the buoy 2 that is away from the buckle 21, so that the buoy 2 can be abutted against the inner wall surface of the housing 1 through the limiting block 25, so that after the first cavity 11 is submerged in water, it is convenient to control the center of gravity of the buoy 2, so that when there is no liquid in the first cavity 11 and the first inlet 12 is not filled with water, the buoy 2 can use its gravity to drive the buckle 21 to rotate in the first direction away from the eccentric shaft 22.

[0071] In some embodiments, a sealing gasket 26 is disposed on the top of the buoy 2, and in the second position, the sealing gasket 26 abuts against the first outlet 13. For example, the sealing gasket 26 is made of elastic material.

[0072] In some embodiments, the slot 15 has a slot slope 151 facing the buoy 2 in the first direction, and the distance between the slot slope 151 and the sliding slot 16 increases downward. Therefore, when the buoy 2 falls and rotates toward the direction adjacent to the slot 15, the slot 15 has enough accommodation space so that the buckle 21 can extend into the slot 15.

[0073] In some embodiments, both sides of the buoy 2 in the second direction are provided with sliding grooves 16, and both ends of the eccentric shaft 22 in the second direction can be slidably and rotatably arranged in the sliding grooves 16. The eccentric shaft 22 is movably arranged in the sliding groove 16. For example, the front and rear walls of the housing 1 are provided with sliding grooves 16 extending in the up-down direction, and both the front and rear ends of the eccentric shaft 22 are movably located in the corresponding sliding grooves 16.

[0074] like Figures 2 to 7As shown, in some embodiments, the eccentric shaft 22 is located at the bottom of the buoy 2 away from the card slot 15 in the first direction, that is, the eccentric shaft 22 and the buckle 21 are located on both sides of the buoy 2 in the first direction. For example, the eccentric shaft 22 is located at the left end of the bottom of the buoy 2.

[0075] like Figure 3 As shown, in the initial state, the float 2 is located at the first position and covers at least part of the second outlet 14, and the buckle 21 on the float 2 is located in the slot 15. That is, in the initial state (when there is no liquid in the first cavity 11), the discharge amount of the first outlet 13 is greater than the discharge amount of the second outlet 14. The buckle 21 cooperates with the slot 15 to limit the cylinder 2.

[0076] like Figure 5 As shown, when the liquid introduced into the first cavity 11 drives the float 2 located at the first position to move upward and continuously impacts the float 2, the buckle 21 located in the clamping groove 15 can limit the float 2 to the first position. Specifically, when the liquid introduced into the first cavity 11 through the first inlet 12 impacts the float 2 to drive the float 2 to move upward, the buckle 21 located in the clamping groove 15 can limit the float 2 to the first position, so that the discharge amount of the first outlet 13 is greater than the discharge amount of the second outlet 14.

[0077] like Figure 6 and Figure 7 As shown, after the liquid is stopped from being introduced into the first cavity 11, the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the first direction along the direction adjacent to the eccentric shaft 22, so that the buckle 21 disengages from the slot 15. When liquid is introduced into the first cavity 11 again after a second preset time, the liquid introduced into the first cavity 11 can drive the float 2 to move to the second position.

[0078] Specifically, Figure 6 As shown, when the liquid is stopped from entering from the first inlet 12 and there is liquid in the first cavity 11, the liquid no longer impacts the float 2, that is, no upward thrust is generated on the float 2. While the eccentric shaft 22 and the counterweight drive the float 2 to fall, the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the first direction along the direction adjacent to the eccentric shaft 22, that is, the buckle 21 rotates in the first direction along the direction away from the slot 15 (to the left), so that the buckle 21 is separated from the slot 15.

[0079] After the second preset time (the buckle 21 is in the state of being out of the card slot 15), the liquid that enters the first cavity 11 from the first inlet 12 again directly impacts the float 2, so that the thrust (impact force) of the liquid can push the float 2 (as well as the eccentric shaft 22 and the counterweight) from the first position to the second position, thereby moving the float 2 to the second position. The continuous impact force of the liquid can make the float 2 stay in the second position, thereby making the discharge amount of the second outlet 14 greater than the discharge amount of the first outlet 13 (such as Figure 7 shown).

[0080] After the liquid is stopped from entering the first inlet 12, the float 2 located at the second position moves downward to the first position, and the float 2 can use its gravity to drive the buckle 21 to rotate in the first direction away from the eccentric shaft 22, so that the buckle 21 extends into the slot 15. Specifically, after the liquid is stopped, the liquid in the first cavity 11 is gradually discharged, and the float 2 can fall. When there is no liquid in the first cavity 11 and the first inlet 12 is not filled with water, the float 2 can use its gravity to drive the buckle 21 to rotate in the first direction away from the eccentric shaft 22. That is, the buckle 21 rotates in the direction adjacent to the slot 15 (to the right), so that the buckle 21 extends into the slot 15 (such as Figure 3 shown).

[0081] like Figure 3 As shown, in some embodiments, in the initial state, the bottom of the float 2 is connected to the bottom surface of the first cavity 11, the first side surface 23 covers at least part of the second outlet 14, the second side surface 24 is spaced from the inner wall surface of the housing 1, the second side surface 24 is tilted upward in the direction adjacent to the first side surface 23, and the top surface of the float 2 is tilted downward in the first direction in the direction adjacent to the first side surface 23. Thus, when water enters the first inlet 12, the liquid can drive the cylinder 2 to move upward, and the buckle 21 moves upward in the slot 15. When the buckle 21 abuts against the top surface of the slot 15, the cylinder 2 is restricted from moving upward. When the first inlet 12 stops entering water and there is water in the first cavity 11, the eccentric shaft 22 and the counterweight drive the float 2 to fall, and the float 2 can rotate (float) relative to the eccentric shaft 22 in the direction away from the slot 15 under the action of its buoyancy, so that the buckle 21 is separated from the slot 15. When the first cavity 11 is submerged in water, the buoy 2 can rotate relative to the eccentric shaft 22 in a direction adjacent to the slot 15 under the action of its gravity. For example, the eccentric shaft 22 is located at the bottom of the left side of the buoy 2. In the initial state, the second side surface 24 is tilted upward and rightward, and the top surface of the buoy 2 is tilted rightward and downward.

[0082] like Figures 8 to 13As shown, in some embodiments, the eccentric shaft 22 is located at the bottom of one side of the buoy 2 adjacent to the slot 15 in the first direction, that is, the eccentric shaft 22 and the buckle 21 are located on the same side of the buoy 2 in the first direction. For example, the eccentric shaft 22 and the buckle 21 are located at the right end of the buoy 2.

[0083] like Fig. 9 As shown, in the initial state, the float 2 is located at the first position and covers at least part of the second outlet 14, and the buckle 21 on the float 2 is located outside the slot 15. That is, in the initial state (when there is no liquid in the first cavity 11), the discharge amount of the first outlet 13 is greater than the discharge amount of the second outlet 14. The buckle 21 is spaced apart from the slot 15 and does not limit the cylinder 2.

[0084] like Fig.11 As shown, the liquid entering the first cavity 11 drives the float 2 located at the first position to move upward to the second position and continuously impacts the float 2. Specifically, the buckle 21 is spaced apart from the card slot 15, and does not limit the cylinder 2, so that the impact force of the liquid entering the first cavity 11 from the first inlet 12 can push the float 2 to move upward to the second position, and continuously impact the float 2, so as to limit the float 2 at the second position, so that the discharge amount of the second outlet 14 is greater than the discharge amount of the first outlet 13.

[0085] like Fig.12 and Fig.13 As shown, after the liquid is stopped from being introduced into the first cavity 11, the eccentric shaft 22 and the counterweight drive the float 2 to move downward to the first position, and the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the first direction along the direction adjacent to the eccentric shaft 22, so that the buckle 21 extends into the slot 15. When liquid is introduced into the first cavity 11 again after the fourth preset time, the buckle 21 located in the slot 15 can limit the float 2 to the first position.

[0086] Specifically, Fig.12 As shown, when the liquid is stopped from entering from the first inlet 12 and there is liquid in the first cavity 11, the liquid no longer impacts the float 2, that is, no upward thrust is generated on the float 2. While the eccentric shaft 22 and the counterweight drive the float 2 to fall, the float 2 can use the liquid in the first cavity 11 to drive the buckle 21 to rotate in the first direction along the direction adjacent to the eccentric shaft 22, that is, the buckle 21 rotates in the first direction along the direction adjacent to the eccentric shaft 22 (rightward), so that the buckle 21 extends into the slot 15.

[0087] After the fourth preset time (the buckle 21 is in the state of being inserted into the slot 15), the liquid entering the first cavity 11 from the first inlet 12 again directly impacts the float 2, and the buckle 21 located in the slot 15 can restrict the float 2 to the first position, so that the discharge amount of the first outlet 13 is greater than the discharge amount of the second outlet 14 (such as Fig.13 shown).

[0088] like Fig. 9 As shown, after the liquid is stopped from entering the first inlet 12, the float 2 can use its gravity to drive the buckle 21 to rotate in the first direction away from the eccentric shaft 22, so that the buckle 21 is separated from the slot 15. Specifically, after the liquid is stopped, the liquid in the first cavity 11 is gradually discharged, and the float 2 can fall. When there is no liquid in the first cavity 11 and the first inlet 12 is not filled with water, the float 2 can use its gravity to drive the buckle 21 to rotate in the first direction away from the eccentric shaft 22. That is, the buckle 21 rotates in the direction away from the slot 15, so that the buckle 21 is separated from the slot 15.

[0089] like Fig. 9 As shown, in the initial state, the bottom of the float 2 is connected to the bottom surface of the first cavity 11, the first side surface 23 covers at least part of the second outlet 14, the distance between the first side surface 23 and the slot 15 in the first direction increases upward, and the first side surface 23 of the float 2 is tilted upward in the direction away from the slot 15, so that the buckle 21 is located outside the slot 15. The bottom surface of the float 2 is tilted downward in the first direction away from the first side surface 23. Thus, when water enters the first inlet 12, the liquid can drive the cylinder 2 to move to the second position. When the first inlet 12 stops entering water and there is water in the first cavity 11, the eccentric shaft 22 and the counterweight drive the float 2 to fall, and the float 2 can rotate (float) relative to the eccentric shaft 22 in the direction adjacent to the slot 15 under the action of its buoyancy, so that the buckle 21 extends into the slot 15. After the buckle 21 extends into the slot 15, when the first inlet 12 is filled with water again, the buckle 21 moves upward in the slot 15, and when the buckle 21 abuts against the top surface of the slot 15, the cylinder 2 is restricted from moving upward. For example, the eccentric shaft 22 is located at the bottom of the right side of the buoy 2. In the initial state, the distance between the first side surface 23 and the slot 15 in the left-right direction increases upward, and the first side surface 23 of the buoy 2 is tilted upward and leftward so that the buckle 21 can be separated from the slot 15. The bottom surface of the buoy 2 is tilted downward and leftward.
