Description

Technical Field

[0001] The present application relates to the field of toilets, and in particular to a steady-flow switching water outlet structure and a toilet. Background Art

[0002] The water system of a toilet includes a main flushing water circuit and a washing water circuit. In some applications, the switching between the main flushing water flow and the washing water circuit is achieved through a mechanical button; in other applications, the switching between the main flushing water circuit and the washing water circuit is achieved through electronic control.

[0003] However, none of the above methods can achieve the simultaneous opening of the two waterways, mainly because the two waterways are set up and controlled separately. Therefore, in some scenarios, the two waterways can be controlled simultaneously through a specific mode of the electronic control system, so that the two waterways can be opened at the same time. However, when the water pressure is high, the waterway has a chaotic water flow problem, and it is necessary to stabilize the waterway that needs to be stabilized by adding a flow stabilizing valve.

[0004] Therefore, the present application studies a steady flow switching water outlet structure which has a steady flow effect on the water channels when the water channels are opened at the same time. Utility Model Content

[0005] In order to have a stabilizing effect on the water channels when the water channels are opened at the same time.

[0006] On the one hand, the present application provides a steady flow switching water outlet structure, which adopts the following technical solution:

[0007] A steady flow switching water outlet structure, comprising a shunt pipe and a control member, wherein the shunt pipe is provided with a water inlet channel, a first water outlet channel and a second water outlet channel, wherein the water inlet channel is respectively connected with the first water outlet channel and the second water outlet channel, and the control member is used to open or close the second water outlet channel; or, the control member is used to open or partially close the second water outlet channel;

[0008] When the control member closes the second water outlet channel, water in the water inlet channel flows out from the first water outlet channel; when the control member opens the second water outlet channel, water in the water inlet channel flows out from the first water outlet channel and the second water outlet channel at the same time.

[0009] By adopting the above technical solution, when in use, one of the first water outlet channel and the second water outlet channel is connected to the main flushing water path of the toilet, and the other is connected to the washing water path of the toilet. When it is necessary to open the two water paths, the second water outlet channel is opened by the control component, and at this time, the water in the water inlet channel can flow out from the first water outlet channel and the second water outlet channel at the same time. Since the first water outlet channel and the second water outlet channel share one water inlet channel, when the water pressure is high, the first water outlet channel and the second water outlet channel realize water flow diversion, slowing down the turbulence of the water flow, thereby achieving a steady flow effect.

[0010] Optionally, the control member has a pre-tightening force, and the control member closes the second water outlet channel under the action of the pre-tightening force. When the water inlet pressure of the water inlet channel is greater than the pre-tightening force, the control member opens the second water outlet channel, and the water in the water inlet channel flows out from the first water outlet channel and the second water outlet channel at the same time.

[0011] By adopting the above technical solution, when the first water outlet channel and the second water outlet channel need to be opened at the same time, the water flow pressure is increased to be greater than the preload force. At this time, the first water outlet channel and the second water outlet channel are opened at the same time to divert the water flow, thereby achieving a steady flow effect.

[0012] Optionally, the control component is a one-way valve assembly, the one-way valve assembly includes a one-way valve core and a spring, and the preload force is the elastic force of the spring;

[0013] When the water inlet pressure of the water inlet channel is greater than the spring force, the one-way valve core opens the second water outlet channel; when the water inlet pressure of the water inlet channel is less than the spring force, the one-way valve core closes the second water outlet channel.

[0014] By adopting the above technical solution and setting the one-way valve, the second water outlet channel can be easily opened or closed.

[0015] Optionally, the one-way valve assembly also includes a guide rod, which is connected to the one-way valve core. The one-way valve assembly also includes a connecting piece fixedly installed in the second water outlet channel, and the connecting piece is penetrated by a sliding hole and is interconnected with the installation channel; the spring is sleeved on the guide rod, and the guide rod passes through the sliding hole and slides with the connecting piece guide.

[0016] Optionally, the control member is a counterweight block, and the pre-tightening force is the gravity of the counterweight block. When the water inlet pressure of the water inlet channel is less than the gravity of the counterweight block, the counterweight block closes the second water outlet channel; when the water inlet pressure of the water inlet channel is greater than the gravity of the counterweight block, the counterweight block opens the second water outlet channel.

[0017] Optionally, a water pump connected to the water inlet channel is also included.

[0018] By adopting the above technical solution, the water flow pressure in the water inlet channel can be changed by the power of the water pump.

[0019] Optionally, the water inlet pressure of the water inlet channel is adjusted by adjusting the output power of the water pump. When the output power of the water pump exceeds a preset power, the water inlet pressure of the water inlet channel is greater than the preload force. When the output power of the water pump does not exceed the preset power, the water inlet pressure of the water inlet channel is less than the preload force.

[0020] On the other hand, the present application provides a toilet, which adopts the following technical solution:

[0021] A toilet comprises a water supply pipe, a main flushing pipe, a cleaning pipe and the above-mentioned steady flow switching water outlet structure, wherein the water inlet channel is connected to the water supply pipe, one of the first water outlet channel and the second water outlet channel is connected to the main flushing pipe, and the other is connected to the cleaning pipe.

[0022] Optionally, the first water outlet channel is connected to the washing pipe, and the second water outlet channel is connected to the main flushing pipe. During the toilet flushing process, the opening and closing of the second water outlet channel is controlled by adjusting the pressure difference between the water inlet pressure of the water inlet channel and the preload force.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In application, when a single water channel needs to be opened, the second water outlet channel is closed by the control component, and the water in the water inlet channel can flow out from the first water outlet channel; when two water channels need to be opened, the second water outlet channel is opened by the control component, and the water in the water inlet channel can flow out from the first water outlet channel and the second water outlet channel at the same time, thereby realizing the switching water supply of different functions. Since the first water outlet channel and the second water outlet channel share a water inlet channel, when the water pressure is high, the first water outlet channel and the second water outlet channel realize water flow diversion, slowing down the turbulence of the water flow, thereby achieving a steady flow effect;

[0025] 2. When the first water outlet channel and the second water outlet channel need to be opened at the same time, the water flow pressure is increased to be greater than the preload force, and the water supply can be easily switched by adjusting the water pressure of the water inlet channel. At this time, the first water outlet channel and the second water outlet channel are opened at the same time to divert the water flow, and the flow of the water outlet channel will not increase due to the increase in the water pressure of the water inlet channel, thereby achieving a steady flow effect;

[0026] 3. The toilet adopts a steady flow switching water outlet structure that can open two water channels at the same time and has a steady flow effect;

[0027] 4. It also includes a water pump connected to the water inlet channel, and the water inlet pressure of the water inlet channel is adjusted by adjusting the output power of the water pump. When the output power of the water pump exceeds the preset power, the water inlet pressure of the water inlet channel is greater than the preload force. When the output power of the water pump does not exceed the preset power, the water inlet pressure of the water inlet channel is less than the preload force. By adopting the above technical solution, the water flow pressure of the water inlet channel can be changed by the power of the water pump, thereby realizing the switching of the water path.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present application embodiment discloses a steady flow switching water outlet structure. Figure 1The steady-flow switching water outlet structure includes a shunt pipe 1 and a control component 2. The shunt pipe 1 is provided with a water inlet channel 3, a first water outlet channel 4 and a second water outlet channel 5. The water inlet channel 3 is respectively connected with the first water outlet channel 4 and the second water outlet channel 5. The control component 2 is used to open or close the second water outlet channel 5; or, the control component 2 is used to open or partially close the second water outlet channel 5. Partially closing the second water outlet channel means that the control component 2 is not completely sealed when closing the second water outlet channel 5, and water can penetrate into the second water outlet channel 5 through the gap, or the control component 2 does not completely close the second water outlet channel 5, that is, the closing position of the control component 2 is artificially controlled to leave part of the space of the second water outlet channel 5 so that water can penetrate.

[0036] When in use, the water inlet channel 3 is connected to the water supply pipe of the toilet, one of the first water outlet channel 4 and the second water outlet channel 5 is connected to the main flushing pipe of the toilet, and the other is connected to the cleaning pipe of the toilet.

[0037] When the control component 2 closes the second water outlet channel 5, the water in the water inlet channel 3 flows out from the first water outlet channel 4; when the control component 2 opens the second water outlet channel 5, the water in the water inlet channel 3 flows out from the first water outlet channel 4 and the second water outlet channel 5 at the same time. When the water pressure is increased, that is, the water flow rate is increased, the first water outlet channel 4 and the second water outlet channel 5 divert the water, slowing down the water flow into the first water outlet channel 4, so that it can play a role in stabilizing the flow.

[0038] In some embodiments, the control member 2 has a preload force, and the control member 2 closes the second water outlet channel 5 under the action of the preload force. When the water inlet pressure of the water inlet channel is greater than the preload force, the control member 2 opens the second water outlet channel 5, and the water in the water inlet channel 3 flows out from the first water outlet channel 4 and the second water outlet channel 5 at the same time. When the water pressure increases, the second water outlet channel 5 can be directly opened to divert the water in the first water outlet channel 4, which plays a role in stabilizing the flow of the first water outlet channel 4. At the same time, the structure is simple, the manufacturing cost is low, it is safe and reliable, and the maintenance cost is low.

[0039] In some embodiments, the control component 2 is a one-way valve assembly, which includes a one-way valve body 21 , a connecting component 22 , a one-way valve cover 23 , a one-way valve core 24 and a spring 25 .

[0040] Reference Figure 2The one-way valve body 21 is provided with an installation channel 6, and the connector 22 is installed in the installation channel 6. In this embodiment, the connector 22 is integrally formed with the one-way valve body 21. In other embodiments, the connector 22 can also be connected by interference fit, snap connection, screw connection, etc.; the connector 22 can also be fixedly installed in the second water outlet channel 5. The connector 22 is provided with a flow hole 7, which is interlinked with the installation channel 6. In this embodiment, four flow holes 7 are evenly spaced around the connector 22, even if the connector 22 is a cross-shaped structure, so that water can flow out of the flow hole 7 through the installation channel 6.

[0041] Reference Figure 3 The one-way valve cover 23 is provided with a connecting hole 8. The one-way valve cover 23 can be detachably mounted on the one-way valve body 21. In this embodiment, the one-way valve cover 23 is connected to the one-way valve body 21 by means of interference fit. In other embodiments, it can also be fixed by means of clamping, screwing, etc. The connecting hole 8 and the installation channel 6 are interconnected. The one-way valve core 24 is arranged in the installation channel 6, and is used to close or open the one-way valve assembly. The two ends of the spring 25 are respectively connected to the one-way valve core 24 and the connecting member 22. When the pressure applied to the one-way valve core 24 is greater than the elastic force of the spring 25, the spring 25 compresses the one-way valve core 24 away from the one-way valve cover 23, and the one-way valve assembly is opened. When the pressure applied to the one-way valve is less than the elastic force of the spring 25, the spring 25 recovers, the one-way valve core 24 blocks the one-way valve cover 23, and the one-way valve assembly is closed.

[0042] When the water inlet pressure of the water inlet channel 3 is greater than the elastic force of the spring 25, the one-way valve core 24 moves away from the one-way valve cover 23, the one-way valve assembly opens, the second water outlet channel 5 opens, water flows in from the connecting hole 8 and flows out from the flow hole 7, and at the same time the first water outlet channel 4 is also in an open state, so that when the first water outlet channel 4 and the second water outlet channel 5 are opened at the same time, they can divert the water inlet, thereby achieving a steady flow effect.

[0043] Reference Figure 4 When the water inlet pressure of the water inlet channel 3 is less than the elastic force of the spring 25 , the second water outlet channel 5 is closed. At this time, the spring 25 returns to its original state, and the one-way valve core 24 approaches the one-way valve cover 23 and abuts against the one-way valve cover 23 .

[0044] When the one-way valve core 24 abuts against the one-way valve cover 23 and covers the communicating hole 8 , the one-way valve assembly is closed, and the second water outlet channel 5 is closed. At this time, water flows out along the first water outlet channel 4 .

[0045] In some embodiments, the one-way valve assembly further includes a guide rod 26, which is connected to the one-way valve core 24. In this embodiment, the guide rod 26 is integrally formed with the one-way valve core 24. The connecting member 22 is provided with a sliding hole 9, which is interlinked with the installation channel 6; the spring 25 is sleeved on the guide rod 26, which passes through the sliding hole 9 and is slidably connected with the connecting member 22. The guide rod 26 guides the one-way valve core 24 in the process of moving away from or approaching the one-way valve cover 23, and can support the spring 25.

[0046] In this embodiment, the one-way valve assembly is connected to the wall surface of the second water outlet channel 5 by means of a snap fit or an interference fit. In this embodiment, the one-way valve body 21 is connected to the wall surface of the second water outlet channel 5 by means of an interference fit, that is, the one-way valve body 21 is connected to the inner wall surface of the diversion pipe 1 corresponding to the second water outlet channel 5 by means of an interference fit.

[0047] In some embodiments, the control member 2 can also be a counterweight block (not shown in the figure), and the preload force is the gravity of the counterweight block. When the water inlet pressure of the water inlet channel 3 is less than the gravity of the counterweight block, the counterweight block closes the second water outlet channel 5; when the water inlet pressure of the water inlet channel 3 is greater than the gravity of the counterweight block, the counterweight block opens the second water outlet channel 5.

[0048] In some embodiments, the steady flow switching water outlet structure further includes a water pump connected to the water inlet channel 3. The water inlet flow pressure can be changed by the power of the water pump.

[0049] The implementation principle of a steady flow switching water outlet structure in the embodiment of the present application is: when in use, one of the first water outlet channel 4 and the second water outlet channel 5 is connected to the main flushing water path of the toilet, and the other is connected to the washing water path of the toilet. When it is necessary to open the two water paths, the second water outlet channel 5 is opened through the control member 2, and at this time, the water in the water inlet channel 3 can flow out from the first water outlet channel 4 and the second water outlet channel 5 at the same time. Since the first water outlet channel 4 and the second water outlet channel 5 share a water inlet channel 3, when the water pressure is high, the first water outlet channel 4 and the second water outlet channel 5 realize water flow diversion, slowing down the turbulence of the water flow, thereby achieving a steady flow effect.

[0050] In some embodiments, the water inlet pressure of the water inlet channel 3 is adjusted by adjusting the output power of the water pump. When the output power of the water pump exceeds the preset power, the water inlet pressure of the water inlet channel 3 is greater than the preload force. When the output power of the water pump does not exceed the preset power, the water inlet pressure of the water inlet channel 3 is less than the preload force.

[0051] The present application also discloses a toilet. Figure 5The toilet includes a water supply pipe, a main flushing pipe 10, a cleaning pipe 11 and the above-mentioned steady flow switching water outlet structure. The water inlet channel 3 is connected to the water supply pipe, and one of the first water outlet channel 4 and the second water outlet channel 5 is connected to the main flushing pipe 10, and the other is connected to the cleaning pipe 11. In some embodiments, the first water outlet channel 4 is connected to the cleaning pipe 11, and the second water outlet channel 5 is connected to the main flushing pipe 10. During the flushing process of the toilet, the opening and closing of the second water outlet channel 5 is controlled by adjusting the pressure difference between the water inlet pressure and the preload force of the water inlet channel 3. This example also includes a water pump 12, which supplies water to the water inlet channel 3 through the water supply pipe, so that the water inlet pressure can be changed.

[0052] The implementation principle of a toilet in an embodiment of the present application is: the toilet adopts a steady-flow switching water outlet structure to open two water channels at the same time, and has a steady-flow effect.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
