Description

Technical Field

[0001] This application relates to the technical field of sanitary ware, and particularly relates to a flushing switching device and a toilet bowl. Background Art

[0002] The flushing of the toilet bowl is directly connected to the auxiliary flushing and the bowl flushing of the toilet bowl by tap water. The flushing of the toilet bowl and the bowl flushing are implemented by controlling devices such as a reversing valve. The reversing valve in the prior art can achieve a quick switching of tap water, and has the advantages of high stability and reliability. However, in some cases, after the water path is switched by the reversing valve in the prior art, the water in the toilet tank will still continue to flow out. For example: when the toilet bowl is full of water and the toilet is flushed, in fact, only a very small part of the water is used. For example, the water level in the toilet tank only drops by 4 - 6 centimeters. At this time, even if the water supply is stopped, the water will still continue to flow out from the outlet of the toilet bowl, resulting in a waste of water resources. Summary of the Utility Model

[0044] Please refer to Figures 1 to 7 , a flushing switching device is provided in the first aspect of this application, including:

[0045] A housing 4, the housing 4 having a first cavity, a first inlet 18, a second inlet, a first outlet 5 and a second outlet 6, the first inlet 18, the second inlet, the first outlet 5 and the second outlet 6 all communicating with the first cavity, the first inlet 18 being for discharging external gas introduced into the first cavity into a water level maintaining pipe 3, the second inlet being for introducing liquid into the interior of the first cavity, the first outlet 5 being located above the second outlet 6;

[0046] A water level maintaining pipe 3, the water level maintaining pipe 3 being connected to a water tank 1 of a toilet via a pump body 2, the water level maintaining pipe 3 having a second cavity, a water outlet 12 and an air inlet 11, the water outlet 12 and the air inlet 11 both communicating with the second cavity, the air inlet 11 being connected to the first inlet 18 via a first connecting pipe 8 for introducing external gas into the second cavity, the water outlet 12 being connected to the second inlet via a second connecting pipe 7, the air inlet 11 being disposed above the water outlet 12 and above the second outlet 6;

[0047] A moving part, at least part of the moving part being movably disposed within the first cavity, the moving part being movable upward from a first position to a second position, at the first position, the moving part being capable of covering at least part of the second outlet 6, at the second position, the moving part being capable of covering at least part of the first outlet 5, the liquid introduced into the first cavity through the second inlet being capable of impinging on the moving part so as to drive the moving part upward;

[0048] A limiting member 10, the limiting member 10 being located within the first cavity, the limiting member 10 being for limiting the moving part; wherein the liquid introduced into the first cavity can, after the moving part is released from the limitation by the limiting member, drive the moving part upward to the second position and restrict the moving part at the second position; after stopping introducing liquid into the first cavity, the moving part located at the second position moves downward to the first position.

[0049] First, the functions of each component are introduced:

[0050] The housing 4 is provided with a first cavity, a first inlet 18, a second inlet, a first outlet 5 and a second outlet 6. Among them, the first cavity serves as the main container for the liquid and is also the area where the moving part moves; the first inlet 18 is for replenishing gas into the water level maintaining pipe 3 to adjust the water level and end the siphon effect, reducing water resource waste, the second inlet is for introducing liquid into the first cavity, the first outlet 5 serves as the main liquid discharge port when the moving part is in the first position; the second outlet 6 serves as the liquid discharge port when the moving part is in the second position, but the discharge of the second outlet 6 stops or significantly reduces after the siphon effect is interrupted by gas.

[0051] A second cavity, a water outlet 12 and an air inlet 11 are provided on the water level maintaining pipe 3. Among them, the second cavity is used to store water; the water outlet 12 is connected to the second inlet through a second connecting pipe 7, allowing the water in the second cavity to flow into the first cavity; the air inlet 11 is used to receive the gas entering through the first connecting pipe 8 from the first inlet 18, which is used to adjust the water level in the second cavity. After using a small amount of water, the gas is introduced into the second cavity, and after destroying the pressure balance in the second cavity, the siphon effect ends, avoiding waste of water resources.

[0052] The moving part can move up and down in the first cavity and adjust its position according to the water level change or the liquid impact force.

[0053] In the first position, at least part of the second outlet 6 is covered, allowing water to flow out through the first water outlet 12. In the second position, at least part of the first outlet 5 is covered, allowing water to flow out through the second outlet 6. It should be noted that when blocking one outlet through the moving part, there will also be some water flowing out of the blocked outlet, and it is not a completely sealed block. This is hereby explained.

[0054] The limiting member 10 is arranged in the housing 4 and is used to limit the moving range of the moving part to ensure that it moves between the correct positions.

[0055] Working principle:

[0056] In the initial state of the device, the moving part is located at the bottom of the first cavity. At this time, the moving part covers most or all of the area of the second outlet 6, while the first outlet 5 is in an open state. Among them, the limiting member 10 is usually integrally formed with the floating cylinder 9, and the floating cylinder and the limiting member are inclined to the right in the initial state.

[0057] When the liquid enters the first cavity through the second inlet, as the liquid continuously flows in, the water level in the first cavity gradually rises. As the water level rises, the impact force of the liquid on the bottom of the moving part gradually increases. When the impact force is sufficient to overcome the gravity of the moving part, the moving part begins to move upward. Among them, during the upward movement of the moving frame 14, the floating cylinder 9 will drive the limiting member 10 to rise together. At this time, since the floating cylinder 4 remains inclined to the right before forming buoyancy, during the upward movement following the moving frame 14, when the limiting member 10 moves to the card slot position, it will be stuck in the card slot, thereby restricting the further upward movement of the moving part, so that during the water inlet process, the moving part can remain in the position covering the second outlet 6.

[0058] After the water supply to the first cavity stops, the moving part starts to move downward under the action of its own gravity. However, due to the limiting effect of the limiting member 10, the moving part will not immediately drop to the initial position. At this time, the float 9 is still partially located in the water, so the float 9 has a certain buoyancy. Since the float 9 is surrounded by water to generate buoyancy, the float will rotate correspondingly to release the limit between the limiting member on the float and the corresponding card slot. At this time, the limiting member 10 is released from the limiting structure, and the moving part will continue to drop under the action of gravity until it returns to the initial position and re-covers the second outlet 6.

[0059] If water needs to be supplied again within a certain period of time after the water supply stops, since there is still a certain amount of liquid remaining in the first cavity and the limiting member 10 has been released from the limiting structure. Therefore, during the secondary water supply, as the water level further rises and the impact force increases, the movement of the moving part will not be hindered by the limiting member 10, and the moving part will continue to rise to cover the first outlet 5, so that the water in the first cavity flows out through the second outlet 6.

[0060] Among them, after using water, when the amount of water flowing out from the second outlet 6 is small, the water level in the water tank 1 drops less. At this time, external gas enters the first cavity through the first outlet 5 and enters the second cavity of the water level maintaining pipe 3 through the first communication pipeline 8. Due to the entry of external gas, when the water level drops to the same height as the first communication pipeline 8, the siphon effect can be ended in advance, and water cannot flow out from the second water outlet 12 of the toilet, thus effectively saving water resources and avoiding waste.

[0061] Optionally, the water level maintaining pipe 3 includes an outer sleeve 13 and an inner sleeve 16; the inner sleeve 16 is sleeved inside the outer sleeve 13, and a second cavity is formed by combining the outer wall of the inner sleeve 16 and the inner wall of the outer sleeve 13 for accommodating liquid; the outer sleeve 13 is provided with the water outlet 12 and the air inlet 11, the air inlet 11 is arranged above the water outlet 12, and the opening area of the water outlet 12 is larger than the opening area of the air inlet 11.

[0062] In the embodiment of the present application, the inner sleeve 16 is sleeved inside the outer sleeve 13, and the gap between the two forms the second cavity. When the water outlet 12 on the outer sleeve 13 starts to drain water, the water level in the second cavity will gradually drop. Since the air inlet 11 is arranged above the water outlet 12, as the water level drops, air enters the second cavity through the air inlet 11, thereby slowing down or stopping the drainage. When the water level rises back to the same height as the air inlet 11, the siphon effect can be ended earlier to avoid wasting water resources.

[0063] Optionally, the first inlet 18 is located on one side of the top of the first cavity, and the second inlet 17 is located on one side of the bottom of the first cavity; the first outlet 5 is located on the other side of the top of the first cavity, and the second outlet 6 is located on the other side of the upper end of the bottom of the first cavity, and the opening direction of the second outlet 6 is inclined downward. The housing 4 includes a first housing and a second housing. The opening of the first housing faces downward, and the opening of the second housing faces upward. The second housing and the first housing define the first cavity. The second housing and the first housing are connected by a buckle, and a sealing ring is provided between the second housing and the first housing. The first inlet 18 and the first outlet 5 are opened on the first housing 4, and the second inlet 17 and the second outlet 6 are opened on the second housing 4.

[0064] In the embodiment of the present application, the second inlet 17 is located on one side of the bottom of the first cavity, so that the water flow enters from the bottom, which can more effectively push the moving part in the first cavity to move upward, and the bottom water inlet also helps to reduce air retention and improve the impact force of the water flow. The first inlet 18 is located on one side of the top of the first cavity. The first inlet 18 is connected to the air inlet 11 on the water level maintaining pipe 3 through the first communication pipeline 8, and is used for when using part of the water, the external gas enters the second cavity through the first inlet 18 and the air inlet 11. When the water level inside the second cavity drops to the same height as the first communication pipeline 8, the siphon effect can be ended earlier to avoid the water from continuing to flow out through the second outlet 6, effectively saving water resources.

[0065] Among them, the housing 4 is divided into a first housing and a second housing and is connected by a buckle. This split design is convenient for assembly and maintenance. At the same time, the buckle connection ensures the stability of the housing 4, and a sealing ring is provided between the second housing and the first housing. The sealing ring can effectively prevent water leakage and improve the sealing performance of the whole device, so as to ensure the normal operation of the flushing switching device and extend its service life.

[0066] Optionally, the moving part includes a moving frame 14 and a floating cylinder 9. The moving frame 14 is movably installed in the first cavity, the floating cylinder 9 is arranged in the moving frame 14, and the floating cylinder 9 is rotatably connected to the moving frame 14.

[0067] In the embodiment of the present application, by arranging the limiting member 10 on the floating cylinder 9, when the floating cylinder 9 moves upward along with the moving frame 14, the limiting member 10 can automatically be stuck into the card slot, thereby restricting the upward movement of the moving part and realizing the automatic limiting function. On the contrary, when the water supply to the first cavity is stopped, the floating cylinder 9 generates buoyancy, and the floating cylinder 9 moves downward relative to the moving frame 14, driving the limiting member 10 to disengage from the card slot, releasing the limit on the moving part, and when the water is supplied again, the limiting member will not be stuck into the card slot, so that the moving part rises to the second position.

[0068] Optionally, the limiting member 10 and the floating drum 9 are integrally formed, and the limiting member 10 is obliquely arranged on one side of the floating drum 9.

[0069] In the embodiment of the present application, the fact that the limiting member 10 and the floating drum 9 are integrally formed means that the connection manner between the limiting member 10 and the floating drum 9 is a non-detachable connection manner, such as integral casting molding, which is not specifically limited herein. The connection manner between the limiting member 10 and the floating drum 9 avoids problems such as looseness, detachment or poor sealing that may be caused by component separation, and improves the overall reliability and durability. At the same time, integral molding also reduces the friction and wear between components and extends the service life of the equipment.

[0070] Optionally, the moving frame 14 is slidably arranged in the first cavity in the up-and-down direction. In the first position, the moving frame 14 can cover at least part of the second outlet 6. In the second position, the moving frame 14 can cover at least part of the first outlet 5; a clamping groove is arranged in the first cavity. When at least part of the limiting member 10 extends into the clamping groove, the upward movement of the moving frame 14 located in the first position can be restricted. After the limiting member 10 extends out of the clamping groove, the limit on the moving frame 14 can be released; the opening of the clamping groove faces the limiting member 10. The limiting member 10 is located between the floating drum 9 and the clamping groove. The clamping groove has a limiting surface facing downward. When the top surface of the limiting member 10 abuts against the limiting surface, the upward movement of the moving frame 14 located in the first position can be restricted.

[0071] In the embodiment of the present application, the moving frame 14 is slidably arranged in the first cavity in the up-and-down direction, so that the moving frame 14 can move in the vertical direction according to the impact force of the liquid entering the first cavity. Among them, the moving frame 14 can switch between two different positions, covering different parts of the second outlet 6 and the first outlet 5 respectively. In the first position, it mainly covers the second outlet 6 to ensure that more water flows out through the first outlet 5; in the second position, it covers the first outlet 5 to make the water flow mainly through the second outlet 6, thereby realizing the switching of the water flow direction.

[0072] Among them, the combined use of the clamping groove and the limiting member 10. When at least part of the limiting member 10 extends into the clamping groove, the top of the limiting block abuts against the limiting surface of the clamping groove, thereby restricting the upward movement of the moving frame 14 and ensuring that the moving frame 14 remains in the first position. When it is necessary to change the water outlet position, only by controlling the inflow and stop of the liquid can the position of the moving frame 14 be changed. For example, when the limiting member 10 extends out of the clamping groove, the limit on the moving frame 14 is released, and the moving frame 14 can move upward to the second position under the impact of the liquid.

[0073] Optionally, a guiding groove extending in the vertical direction is provided in the first cavity, and a guiding post extending into the guiding groove is provided on the moving frame 14; a counterweight 15 is provided on the moving frame 14, and a sealing gasket is provided on the top of the moving frame 14. When the moving frame 14 reaches the first position, the sealing gasket is away from the first outlet 5. When the moving frame 14 reaches the second position, the sealing gasket seals the first outlet 5.

[0074] In the embodiment of the present application, the guiding groove extending in the vertical direction provided in the first cavity cooperates with the guiding post extending into the moving frame 14 to provide an accurate vertical movement path for the moving frame 14, ensuring the stability and accuracy of the moving frame 14 during the up and down movement, and avoiding shaking or deviation during the movement.

[0075] The tight cooperation between the guiding groove and the guiding post also enhances the connection strength between the moving frame 14 and the housing 4, making the entire flushing switching device more stable and reliable during operation.

[0076] The counterweight 15 provided on the moving frame 14 helps to balance the center of gravity of the moving frame 14 and increase its stability in the stationary state. At the same time, during the downward movement of the moving frame 14, the presence of the counterweight 15 can accelerate its falling speed, improve the response speed of the flushing switching, and the presence of the counterweight 15 also shares the impact force during the movement of the moving frame 14, reducing the wear on other components, thereby extending the service life of the entire flushing switching device.

[0077] The sealing gasket provided on the top of the moving frame 14 plays a key sealing role when the moving frame 14 reaches different positions. When the moving frame 14 reaches the first position, the sealing gasket is away from the first outlet 5, which does not affect the drainage of the first outlet 5; when the moving frame 14 reaches the second position, the sealing gasket tightly seals the first outlet 5, ensuring that the water flow mainly discharges through the second outlet 6, and the good sealing performance of the sealing gasket also prevents possible leakage problems during the flushing process, improving the overall performance and user experience of the flushing switching device.

[0078] Wherein, the flushing switching device further includes a pump body 2. The pump body 2 is communicated with the bottom of the inner sleeve 16 through a water inlet pipe. The pump body 2 is used to control the liquid to be introduced into the first cavity through the water outlet 12 on the water level maintaining pipe 3.

[0080] a water tank 1 and a toilet body;
