- One end of the flush-ring water supply component 4 is in communication with the flush-ring water delivery pipe 13, and another end of the flush-ring water supply component 4 is in communication with the water intake device 2.
- the flush-ring water supply component 4 is provided with an ejecting mechanism in communication with the water storage tank 11. When water flows from the water intake device 2 to the flush-ring water delivery pipe 13, negative pressure is generated in the ejecting mechanism, such that water stored in the water storage tank 11 is sucked towards the flush-ring water delivery pipe 13.
- the spraying-type water delivery pipe 14 is independently arranged in the toilet body 1, and the spraying-type water delivery pipe 14 is provided with only two openings, including a water inlet in communication with an output end of the drain valve 3 and a water spray opening 141 in communication with the bottom of the toilet bowl 12. That is, the spraying-type water delivery pipe 14 is a closed pipe, and the only two openings thereof are the water inlet and the water spray opening 141.
- the water inlet of the spraying-type water delivery pipe 14 is in communication with the output end of the drain valve 3, and the water spray opening 141 of the spraying-type water delivery pipe 14 is in communication with the bottom of the toilet bowl 12.
- the water intake device 2 is connected to a water supply system, and water provided by the water intake device 2 is directly delivered to the flush-ring water delivery pipe 13 through the flush-ring water supply component 4, and when the water passes through the ejecting mechanism of the flush-ring water supply component 4, negative pressure is generated in the ejecting mechanism. Since the ejecting mechanism is in communication with the water storage tank 11, the water stored in the water storage tank 11 flows into the ejecting mechanism, then flows to the flush-ring water delivery pipe 13 along the flush-ring water supply component 4, and then flows out from flushing holes 131 in the flush-ring water delivery pipe 13, to flush downward from the surface of the toilet seat of the toilet bowl 12.

- the drain valve 3 When the flushing process is finished, the drain valve 3 is closed, the water inlet of the spraying-type water delivery pipe 14 that is in communication with the output end of the drain valve 3 is closed, another end (where the water spray opening 141 is located) of the spraying-type water delivery pipe 14 is closed by the water in the toilet bowl 12.
- the spraying-type water delivery pipe 14 is an independent pipe, and the only two openings (the water inlet and the water spray opening 141) thereof are both closed, especially for the water inlet at a relatively high water level, when the drain valve 3 is closed (that is, in a non-draining state), the water inlet is closed, the drain valve 3 seals the water inlet of the spraying-type water delivery pipe 14 to isolate the end of the spraying-type water delivery pipe 14, where the water inlet is located, from the outside air; the water spray opening 141 is closed by the water in the toilet bowl 12, thus under the atmospheric pressure, the water in the spraying-type water delivery pipe 14 will not flow out from the water spray opening 141, but fills the spraying-type water delivery pipe 14, that is, the spraying-type water delivery pipe 14 is filled with water.
- a pipeline pressure of the water intake device 2 is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component 4, water is allowed to flow upward, therefore, the position of the bottom surface of the water storage tank 11 can be effectively lowered.
- the position of the water inlet of the spraying-type water delivery pipe 14 is lowered, which effectively reduces the height of the spraying-type water delivery pipe 14 in the vertical direction.
- a path length of the spraying-type water delivery pipe 14 is decreased, which reduces the energy loss in the spraying-type water delivery pipe 14.
- the spraying-type water delivery pipe 14 When the flushing process is performed again, because the spraying-type water delivery pipe 14 is filled with water, the water in the spraying-type water delivery pipe 14 directly flushes the bottom of the toilet bowl 12 through the water spray opening 141, an operation of discharging the air in the spraying-type water delivery pipe 14 is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency.
- the bottom surface of the water storage tank 11 is arranged to be lower than the surface of the toilet seat of the toilet bowl 12, so that under the condition that the water storage tank 11 has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs.

Description
- The present application relates to the technical field of sanitary wares, and particularly relates to a low water level toilet.
- At present, most toilets use ceramic materials, and with the increasing popularity and use of the toilets, the amount of generated ceramic waste is also increasing. Therefore, people are increasingly inclined to designs of toilets using less materials, so as to save resources and reduce pollution.
- Reference is made to
Figure 1 , which is a schematic view showing the structure of a toilet in the conventional technology. - The toilet includes a
water storage tank 01, atoilet bowl 02 and a subsequentsewage drain pipe 07 and so on. - A drain valve is provided in the
water storage tank 01, and when the drain valve is opened, water in thewater storage tank 01 flows into a commonsub water channel 03, and then flows into a flush-ringwater delivery pipe 04 and a spraying-typewater delivery pipe 05. The flush-ringwater delivery pipe 04 is arranged at a surface of a toilet seat, and the flush-ringwater delivery pipe 04 is provided with flushingholes 041 for flushing thetoilet bowl 02 from top to bottom. One end of the spraying-typewater delivery pipe 05 is a spraying opening 051 for flushing a bottom of thetoilet bowl 02. Because thewater storage tank 01 is required to supply water to the flush-ringwater delivery pipe 04, thewater storage tank 01 is required to be designed to have a height above the surface of the toilet seat, so that a working water level of thewater storage tank 01 can be ensured to be higher than the surface of the toilet seat, to provide enough potential energy to drive the water to flow into the flush-ringwater delivery pipe 04 to clean thetoilet bowl 02, and to generate siphonage at the same time. However, the higher thewater storage tank 01 is, the more the ceramic is used, thus, not only the production costs are increased, the resource consumption and environmental pollution are also increased. - In a case that the water storage tank of the toilet is designed to be flush with the surface of the toilet seat, the consumption of ceramic materials will be greatly reduced. It is estimated that with this design, the consumption of ceramic materials can be reduced about 12 kilograms for one toilet. However, since the working water level of the water storage tank is lower than the surface of the toilet seat, that is, the water in the water storage tank cannot flow into a pipe at the toilet seat to flush the toilet bowl, and with such low potential energy, the sewage drain pipe can hardly generate siphonage.
- Therefore, an issue to be addressed by those skilled in the art is to ensure flushing efficiency while reducing the resource consumption and the production costs.
- In view of this, a low water level toilet is provided according to the present application, to reduce resource consumption and production costs, as well as to ensure flushing efficiency.

- Preferably, in the low water level toilet, the switching device includes:
- a rotation shaft rotatably arranged on the ejecting pipe; and
- a baffle connected to the rotation shaft and configured to open or close an inner channel of the ejecting pipe.
- Preferably, the low water level toilet further includes a linkage device connected to the switching device and the drain valve, and a drain button of the low water level toilet is connected to the linkage device; and
when the drain button is pressed, the linkage device drives the rotation shaft to rotate, and the baffle opens the ejecting pipe; and
a water level in the water storage tank drops, a buoy of the drain valve falls, the drain valve is closed and drives the linkage device to reset, the rotation shaft is no longer limited by the linkage device, and under an action of water flow in the ejecting pipe, the baffle drives the rotation shaft to rotate to close the ejecting pipe. - Preferably, in the low water level toilet, the switching device further includes a switching floater connected to the rotation shaft; and
when a water level in the water storage tank is maintained at a rated water level, the switching floater remains stationary, and the baffle is in a state of opening the ejecting pipe; and
when the water level in the water storage tank drops, the switching floater falls to drive the rotation shaft to rotate, and the baffle closes the ejecting pipe. - Preferably, in the low water level toilet, the switching device further includes a water replenishment adjusting block arranged on an inner wall of the ejecting pipe;
a gap is provided between a free end of the baffle and an inner side face, facing an interior of the ejecting pipe, of the water replenishment adjusting block; and the water replenishment adjusting block is a movable block movable in an axial direction of the ejecting pipe;
the inner side face of the water replenishment adjusting block is obliquely arranged along the axial direction of the ejecting pipe, and the water replenishment adjusting block has a protruding end sticking out of an outer wall of the ejecting pipe; and
the outer wall of the ejecting pipe is provided with a dividing rule arranged corresponding to the protruding end. - Preferably, in the low water level toilet, the switching device includes a second communicating pipe in communication with the water storage tank, a first communicating pipe in communication with the flush-ring water supply component, a water intake tube in communication with the water outlet of the water intake device, and a water distribution switch configured to switch the water intake tube between two states, to allow the water intake tube to be in communication with the second communicating pipe or in communication with the first communicating pipe.
- Preferably, in the low water level toilet, the switching device further includes:
- a switch linkage component connected to the water distribution switch;
- a switch buoy connected to the switch linkage component, wherein during a falling process of the switch buoy, the water distribution switch is driven to switch from a state that the water intake tube is in communication with the first communicating pipe to a state that the water intake tube is in communication with the second communicating pipe; and
- a time-delay cavity having an opening facing upward, wherein the switch buoy is located inside the time-delay cavity, and a bottom of the time-delay cavity is provided with a water leaking opening.
- Preferably, the low water level toilet is further provided with an overflow pipe mutually independent with respect to the spraying-type water delivery pipe, wherein the overflow pipe is integrally formed with the water storage tank or independently arranged inside the water storage tank, and the overflow pipe is in communication with the flush-ring water delivery pipe.
- It can be seen from the above technical solutions that, in the low water level toilet according to the present application, during a flushing process, the water intake device is connected to a water supply system, and water provided by the water intake device is directly delivered to the flush-ring water delivery pipe through the flush-ring water supply component, and when the water passes through the ejecting mechanism of the flush-ring water supply component, negative pressure is generated in the ejecting mechanism. Since the ejecting mechanism is in communication with the water storage tank, the water stored in the water storage tank flows into the ejecting mechanism, then flows to the flush-ring water delivery pipe along the flush-ring water supply component, and then flows out from flushing holes in the flush-ring water delivery pipe, to flush downward from the surface of the toilet seat of the toilet bowl. One end of the spraying-type water delivery pipe is in communication with the output end of the drain valve, the drain valve is opened, the water in the water storage tank flows from the water inlet of the spraying-type water delivery pipe into the spraying-type water delivery pipe through the drain valve, then flushes the bottom of the toilet bowl via the water spray opening of the spraying-type water delivery pipe, and then is drained out via a sewage drain pipe at the bottom of the toilet bowl. When the flushing process is finished, the drain valve is closed, the water inlet of the spraying-type water delivery pipe that is in communication with the output end of the drain valve is closed, another end, that is the water spray opening is closed by the water in the toilet bowl. Since the spraying-type water delivery pipe is an independent pipe, and the only two openings, that is the water inlet and the water spray opening, are both closed, especially for the water inlet at a relatively high water level, when the drain valve is closed, the water inlet is closed; the water spray opening is closed by the water in the toilet bowl, thus under the atmospheric pressure, the water in the spraying-type water delivery pipe will not flow out from the water spray opening, but fills the spraying-type water delivery pipe, that is, the spraying-type water delivery pipe is filled with water.
- With the above arrangements, a pipeline pressure of the water intake device is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component, water is allowed to flow upward, therefore, the position of the bottom surface of the water storage tank can be effectively lowered. The position of the water inlet of the spraying-type water delivery pipe is lowered, which effectively reduces the height of the spraying-type water delivery pipe in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-type water delivery pipe is unchanged, a path length of the spraying-type water delivery pipe is decreased, which reduces the energy loss in the spraying-type water delivery pipe. When the flushing process is performed again, because the spraying-type water delivery pipe is filled with water, the water in the spraying-type water delivery pipe directly flushes the bottom of the toilet bowl through the water spray opening, an operation of discharging the air in the spraying-type water delivery pipe is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency. The bottom surface of the water storage tank is arranged to be lower than the surface of the toilet seat of the toilet bowl, so that under the condition that the water storage tank has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs.

- Referring to
Figures 2 to 6 ,Figure 2 is a schematic view showing the structure of a low water level toilet according to a first embodiment of the present application;Figure 3 is a schematic view showing the low water level toilet in a first state according to the first embodiment of the present application;Figure 4 is a partially enlarged view of portion A inFigure 3 ;Figure 5 is a schematic view showing the low water level toilet in a second state according to the first embodiment of the present application; andFigure 6 is a partially enlarged view of portion B inFigure 5 . - A low water level toilet is provided according to an embodiment of the present application, which includes a toilet body 1, a
water intake device 2, adrain valve 3, a flush-ringwater supply component 4 and aswitching device 5. The toilet body 1 is provided with awater storage tank 11, atoilet bowl 12, a flush-ringwater delivery pipe 13 and a spraying-typewater delivery pipe 14. The flush-ringwater delivery pipe 13 is located near a surface of a toilet seat of thetoilet bowl 12, and is used to flush a peripheral wall of thetoilet bowl 12. The spraying-typewater delivery pipe 14 is in communication with both a bottom of thewater storage tank 11 and a bottom of thetoilet bowl 12, and is used to flush the bottom of thetoilet bowl 12. Thewater intake device 2, thedrain valve 3 and the flush-ringwater supply component 4 are all arranged inside thewater storage tank 11. One end of the flush-ringwater supply component 4 is in communication with the flush-ringwater delivery pipe 13, and another end of the flush-ringwater supply component 4 is in communication with thewater intake device 2. The flush-ringwater supply component 4 is provided with an ejecting mechanism in communication with thewater storage tank 11. When water flows from thewater intake device 2 to the flush-ringwater delivery pipe 13, negative pressure is generated in the ejecting mechanism, such that water stored in thewater storage tank 11 is sucked towards the flush-ringwater delivery pipe 13. - The spraying-type
water delivery pipe 14 is independently arranged in the toilet body 1, and the spraying-typewater delivery pipe 14 is provided with only two openings, including a water inlet in communication with an output end of thedrain valve 3 and awater spray opening 141 in communication with the bottom of thetoilet bowl 12. That is, the spraying-typewater delivery pipe 14 is a closed pipe, and the only two openings thereof are the water inlet and thewater spray opening 141. The water inlet of the spraying-typewater delivery pipe 14 is in communication with the output end of thedrain valve 3, and thewater spray opening 141 of the spraying-typewater delivery pipe 14 is in communication with the bottom of thetoilet bowl 12. - For the low water level toilet according to the embodiment of the present application, during a flushing process, the
water intake device 2 is connected to a water supply system, and water provided by thewater intake device 2 is directly delivered to the flush-ringwater delivery pipe 13 through the flush-ringwater supply component 4, and when the water passes through the ejecting mechanism of the flush-ringwater supply component 4, negative pressure is generated in the ejecting mechanism. Since the ejecting mechanism is in communication with thewater storage tank 11, the water stored in thewater storage tank 11 flows into the ejecting mechanism, then flows to the flush-ringwater delivery pipe 13 along the flush-ringwater supply component 4, and then flows out from flushingholes 131 in the flush-ringwater delivery pipe 13, to flush downward from the surface of the toilet seat of thetoilet bowl 12. One end of the spraying-typewater delivery pipe 14 is in communication with the output end of thedrain valve 3, thedrain valve 3 is opened, the water in thewater storage tank 11 flows from the water inlet of the spraying-typewater delivery pipe 14 into the spraying-typewater delivery pipe 14 through thedrain valve 3, then flushes the bottom of thetoilet bowl 12 via thewater spray opening 141 of the spraying-typewater delivery pipe 14, and then is drained out via asewage drain pipe 16 at the bottom of thetoilet bowl 12. When the flushing process is finished, thedrain valve 3 is closed, the water inlet of the spraying-typewater delivery pipe 14 that is in communication with the output end of thedrain valve 3 is closed, another end (where thewater spray opening 141 is located) of the spraying-typewater delivery pipe 14 is closed by the water in thetoilet bowl 12. Since the spraying-typewater delivery pipe 14 is an independent pipe, and the only two openings (the water inlet and the water spray opening 141) thereof are both closed, especially for the water inlet at a relatively high water level, when thedrain valve 3 is closed (that is, in a non-draining state), the water inlet is closed, thedrain valve 3 seals the water inlet of the spraying-typewater delivery pipe 14 to isolate the end of the spraying-typewater delivery pipe 14, where the water inlet is located, from the outside air; thewater spray opening 141 is closed by the water in thetoilet bowl 12, thus under the atmospheric pressure, the water in the spraying-typewater delivery pipe 14 will not flow out from thewater spray opening 141, but fills the spraying-typewater delivery pipe 14, that is, the spraying-typewater delivery pipe 14 is filled with water. - With the above arrangements, a pipeline pressure of the
water intake device 2 is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ringwater supply component 4, water is allowed to flow upward, therefore, the position of the bottom surface of thewater storage tank 11 can be effectively lowered. The position of the water inlet of the spraying-typewater delivery pipe 14 is lowered, which effectively reduces the height of the spraying-typewater delivery pipe 14 in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-typewater delivery pipe 14 is unchanged, a path length of the spraying-typewater delivery pipe 14 is decreased, which reduces the energy loss in the spraying-typewater delivery pipe 14. When the flushing process is performed again, because the spraying-typewater delivery pipe 14 is filled with water, the water in the spraying-typewater delivery pipe 14 directly flushes the bottom of thetoilet bowl 12 through thewater spray opening 141, an operation of discharging the air in the spraying-typewater delivery pipe 14 is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency. The bottom surface of thewater storage tank 11 is arranged to be lower than the surface of the toilet seat of thetoilet bowl 12, so that under the condition that thewater storage tank 11 has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs. - Further, a top surface of the
water storage tank 11 and a top surface of thetoilet bowl 12 lie in a same plane. With the above arrangement, the water storage tank 11 (at least a water surface inside the water storage tank 11) is not required to be higher than the surface of the toilet seat of thetoilet bowl 12. It should be understood that, the height of thewater storage tank 11 is not limited by the position of the flush-ringwater delivery pipe 13, thereby facilitating the production of the toilet body 1, effectively reducing the material consumption of the toilet body 1, reducing the volume of the low water level toilet, and further facilitating the installation of the low water level toilet. The top surface of thewater storage tank 11 may also be higher or lower than the top surface of thetoilet bowl 12. - The ejecting mechanism of the flush-ring
water supply component 4 includes an ejectingpipe 41 in communication with the flush-ringwater delivery pipe 13 and awater intake pipe 42 in communication with a water outlet of thewater intake device 2. The ejecting mechanism employs the Venturi principle, as long as a diameter of an end, facing thewater intake pipe 42, of the ejectingpipe 41 is greater than a diameter of an end, facing the ejectingpipe 41, of thewater intake pipe 42, when the water rapidly flows from thewater intake pipe 42 to the ejectingpipe 41, negative pressure is generated, which sucks the water stored in thewater storage tank 11 towards the ejectingpipe 41. In this embodiment, the end, facing thewater intake pipe 42, of the ejectingpipe 41 is an outwardly flaredopening 411, and an end, inserted into the outwardly flaredopening 411, of thewater intake pipe 42 is an inwardlynecked opening 421. The outwardly flaredopening 411 cooperates with the inwardlynecked opening 421, to form a Venturi structure. Since the flush-ringwater supply component 4 is located inside thewater storage tank 11, the outwardly flaredopening 411 is in communication with thewater storage tank 11. After the water delivered by thewater intake device 2 passes through the inwardlynecked opening 421, the pressure at a joint between the outwardly flaredopening 411 and the inwardlynecked opening 421 drops, thus the water in thewater storage tank 11 is driven to enter the ejectingpipe 41 from the outwardly flaredopening 411, and then flows toward the flush-ringwater delivery pipe 13 together with the water delivered by thewater intake device 2. With the above arrangements, a flush volume of the flush-ringwater delivery pipe 13 is effectively increased. - In this embodiment, an end, opposite to the
water intake pipe 42, of the ejectingpipe 41 is in communication with the flush-ringwater delivery pipe 13 through a connectinghose 43. - Further, the low water level toilet also includes a
switching device 5 configured to switch thewater intake device 2 between two states, to allow thewater intake device 2 to be in communication with the flush-ringwater supply component 4 or thewater storage tank 11. That is, through the switching of theswitching device 5, the communication between thewater intake device 2 and the flush-ringwater supply component 4 or the communication between thewater intake device 2 and thewater storage tank 11 is realized. One end of the flush-ringwater supply component 4 is in communication with the flush-ringwater delivery pipe 13, another end of the flush-ringwater supply component 4 is in communication with thewater intake device 2, thus in a case that thewater intake device 2 is in communication with the flush-ringwater supply component 4, the water delivered out of the water outlet of thewater intake device 2 passes through the flush-ringwater supply component 4 and then flows into the flush-ringwater delivery pipe 13; and in a case that thewater intake device 2 is in communication with thewater storage tank 11, the water delivered out of the water outlet of thewater intake device 2 flows into thewater storage tank 11. By operating theswitching device 5, the communication between thewater intake device 2 and the flush-ringwater supply component 4 and the communication between thewater intake device 2 and thewater storage tank 11 are regulated, which facilitates the regulation of an amount of the water supplied from thewater intake device 2 to the flush-ringwater delivery pipe 13 and thewater storage tank 11. - As shown in
Figures 7 to 10 , in a first embodiment, theswitching device 5 includes abaffle 51 and arotation shaft 52. Therotation shaft 52 is rotatably arranged on the ejectingpipe 41, thebaffle 51 is connected to therotation shaft 52 and is used for opening or closing an inner channel of the ejectingpipe 41. As shown inFigure 4 , when thebaffle 51 closes the inner channel of the ejectingpipe 41, the water delivered by thewater intake pipe 42 flows into thewater storage tank 11 through the opening (the outwardly flared opening 411) of the ejectingpipe 41. As shown inFigure 6 , when thebaffle 51 opens the inner channel of the ejectingpipe 41, the water delivered by thewater intake pipe 42 flows into the flush-ringwater delivery pipe 13 along the ejectingpipe 41. That is, it is only needed to control therotation shaft 52 to rotate, thus the structure is simple, and the control is convenient. - In order to allow the
switching device 5 to switch automatically, the low water level toilet further includes alinkage device 6 connected to theswitching device 5 and thedrain valve 3, and a drain button 8 of the low water level toilet is connected to thelinkage device 6. When the drain button 8 is pressed, thelinkage device 6 drives therotation shaft 52 to rotate, and thebaffle 51 opens the ejectingpipe 41. - The water level in the
water storage tank 11 drops, a buoy of thedrain valve 3 falls, thedrain valve 3 is closed and drives thelinkage device 6 to reset, therotation shaft 52 is no longer limited by thelinkage device 6, and thus under the action of the water flow in the ejectingpipe 41, thebaffle 51 drives therotation shaft 52 to rotate to close the ejectingpipe 41. - In this embodiment, the
rotation shaft 52 is provided with aswitch connecting block 53, thelinkage device 6 is provided with alinkage connecting block 61 connected to theswitch connecting block 53, and thelinkage connecting block 61 is insertedly connected to a connecting slot of theswitch connecting block 53. When it is required to flush the toilet, the drain button 8 is pressed, thedrain valve 3 is opened, and one end of thelinkage device 6 falls, another end of thelinkage device 6 that is provided with thelinkage connecting block 61 rises, thereby driving theswitch connecting block 53 to move in a trend of moving upward, to allow therotation shaft 52 to rotate. Taking the direction shown inFigure 8 as an example, therotation shaft 52 rotates anticlockwise, to drive thebaffle 51 to rotate, thereby opening the ejectingpipe 41. When the flushing process is finished, the water level in thewater storage tank 11 drops, the buoy of thedrain valve 3 falls, thedrain valve 3 is closed and drives thelinkage device 6 to reset, therotation shaft 52 is no longer limited by thelinkage device 6, and under the action of the water flow in the ejectingpipe 41, thebaffle 51 drives therotation shaft 52 to rotate to close the ejectingpipe 41. Taking the direction shown inFigure 8 as an example, thebaffle 51 drives therotation shaft 52 to rotate clockwise, thereby closing the ejectingpipe 41. The above arrangement facilitates the switching operation. - As shown in
Figure 9 , when it is required to flush the toilet, thelinkage connecting block 61 for driving thelinkage device 6 rises, and in turn drives theswitch connecting block 53 to move in the trend of moving upward, to allow therotation shaft 52 to rotate. When the flushing process is finished, thelinkage connecting block 61 of thelinkage device 6 falls, the downward movement of theswitch connecting block 53 is not limited; the water flow in the ejectingpipe 41 flows to impact thebaffle 51, and then drives thebaffle 51 to rotate. - The
switch connecting block 53 may also be embodied as a gear wheel, and thelinkage connecting block 61 may be embodied as a gear rack engaged with the gear wheel. - As shown in
Figures 11 and 12 , in a second embodiment, theswitching device 5 further includes a switchingfloater 55 connected to therotation shaft 52. When the water level in thewater storage tank 11 is maintained at a rated water level, the switching floater remains stationary, and thebaffle 51 is in a state of opening the ejectingpipe 41; and when the water level in thewater storage tank 11 drops, the switchingfloater 55 falls to drive therotation shaft 52 to rotate, and thebaffle 51 closes the ejectingpipe 41. As shown inFigure 12 , when water is not flushed, the switchingfloater 55 floats at the rated water level, thebaffle 51 attaches to an inner wall of the ejectingpipe 41 under the action of the switchingfloater 55, and the ejectingpipe 41 is opened. After thedrain valve 3 is opened, the water level in thewater storage tank 11 falls, the switchingfloater 55 falls with the falling of the water level, which drives therotation shaft 52 to rotate clockwise, to drive thebaffle 51 to rotate, thereby closing the ejectingpipe 41. With the above arrangement, theswitching device 5 and thedrain valve 3 are separately arranged, thereby facilitating repair and maintenance. - As shown in
Figures 10 and12 , in both the first embodiment and the second embodiment, theswitching device 5 is further provided with a waterreplenishment adjusting block 54. The waterreplenishment adjusting block 54 is arranged on the inner wall of the ejectingpipe 41. A gap is provided between a free end of thebaffle 51 and an inner side face of the waterreplenishment adjusting block 54. The arrangement of the waterreplenishment adjusting block 54 facilitates the adjustment of the gap between the free end of thebaffle 51 and the inner side face, facing an interior of the ejectingpipe 41, of the waterreplenishment adjusting block 54. In a case that theswitching device 5 allows thewater intake device 2 to be in communication with thewater storage tank 11, due to the above gap structure, water can still flow from thewater intake device 2 to the flush-ringwater supply component 4, so that water can be replenished into thetoilet bowl 12 to function as water seal. The arrangement of the waterreplenishment adjusting block 54 facilitates the adjustment of the size of the gap. - In this embodiment, the water
replenishment adjusting block 54 is movable in an axial direction of the ejectingpipe 41, and the inner side face of the waterreplenishment adjusting block 54 is obliquely arranged along the axial direction of the ejectingpipe 41. In a process that the waterreplenishment adjusting block 54 moves in the axial direction of the ejectingpipe 41, a distance (that is, the size of the gap) between the inner side face of the waterreplenishment adjusting block 54 and the free end of thebaffle 51 is adjusted. - The water
replenishment adjusting block 54 may also be allowed to move in a radial direction of the ejectingpipe 41, or water replenishment adjusting blocks 54 having different thicknesses may also be used for substitution, which will not be described in detail herein. - In this embodiment, the water
replenishment adjusting block 54 is provided with a serrated face cooperating with the ejectingpipe 41, to improve the positioning effect of the waterreplenishment adjusting block 54. - Further, the water
replenishment adjusting block 54 is provided with a protruding end sticking out of an outer wall of the ejectingpipe 41; and the outer wall of the ejectingpipe 41 is provided with a dividing rule corresponding to the protruding end. By adjusting the protruding end corresponding to the dimension of the dividing rule, the distance between the inner side face of the waterreplenishment adjusting block 54 and the free end of thebaffle 51 is adjusted. - As shown in
Figures 13 to 17 , in a third embodiment, the water inletting of thewater intake device 2 is controlled by a switch lifting rod 58' and a water intake buoy 52' controlling the switch lifting rod 58'. Theswitching device 5 includes a second communicating pipe 56', a first communicating pipe 57', a water intake tube and a water distribution switch 51'. The second communicating pipe 56' is in communication with thewater storage tank 11, the first communicating pipe 57' in communication with the flush-ringwater supply component 4, the water intake tube is in communication with the water outlet of thewater intake device 2, and the water distribution switch 51' is configured to switch the water intake tube between two states, to allow the water intake tube to be in communication with the second communicating pipe 56' or the first communicating pipe 57', that is, through the switching of the water distribution switch 51', the communication between the water intake tube and the second communicating pipe 56' or the communication between the water intake tube and the first communicating pipe 57' is realized. - As shown in
Figure 18 , in this embodiment, similarly an ejecting mechanism is provided in the flush-ringwater supply component 4, the ejecting mechanism includes an ejectingpipe 41 and awater intake pipe 42, and a diameter of thewater intake pipe 42 is smaller than a diameter of the ejectingpipe 41. In this embodiment, preferably, the ejectingpipe 41 and thewater intake pipe 42 are embodied as an integral structure, and this position is provided with an opening (not shown in the figure) in communication with thewater storage tank 11. The ejecting mechanism forms a Venturi structure having one end connected to thewater intake device 2 through awater intake hose 7 and another end connected to the flush-ringwater delivery pipe 13 through the connectinghose 43. - Further, in order to realize automatic switching of the
switching device 5, theswitching device 5 further includes a switch linkage component 55' and a switch buoy 53'. The switch lifting rod 58' is connected to thewater intake device 2 and the water intake buoy 52', and when the water intake buoy 52' falls, thewater intake device 2 is opened for inletting water. A time-delay cavity 54' has an opening facing upward, the switch buoy 53' is located inside the time-delay cavity 54', and the time-delay cavity 54' is provided with a water leaking opening at its bottom. In a process of water descending in thewater storage tank 11, the water in the time-delay cavity 54' flows out from the water leaking opening, and the delayed duration depends on the size of the water leaking opening. The switch buoy 53' falls with the increase of the amount of water leaked from the time-delay cavity 54', thereby driving the switch linkage component 55' to rotate. As shown inFigures 16 and17 , in this embodiment, the switch linkage component 55' drives the water distribution switch 51' to rotate anticlockwise, thereby driving the water distribution switch 51' to switch from a state that the water intake tube is in communication with the first communicating pipe 57' to a state that the water intake tube is in communication with the second communicating pipe 56'. After the time-delay cavity 54' is emptied, the switch buoy 53' falls to the lowest point. - In this embodiment, the low water level toilet is further provided with an
overflow pipe 15 mutually independent with respect to the spraying-typewater delivery pipe 14. Theoverflow pipe 15 is integrally formed with thewater storage tank 11 or independently arranged inside thewater storage tank 11, and theoverflow pipe 15 is in communication with the flush-ringwater delivery pipe 13. - According to the embodiment in which the
overflow pipe 15 is integrally formed with thewater storage tank 11, an overflow inlet of theoverflow pipe 15 is located at a side wall of thewater storage tank 11. The above arrangement effectively facilitates overflow draining. That is, an overflow opening is directly machined in an inner wall of thewater storage tank 11, so that water will flow out from the overflow opening when there is too much water in thewater storage tank 11. - Preferably, the
overflow opening 15 is in communication with the flush-ringwater delivery pipe 13. It is also possible that an independent channel is provided in an entity portion of the toilet body 1 of the toilet, so that the water from theoverflow pipe 15 can flow into thetoilet bowl 12. - According to the embodiment in which the
overflow pipe 15 is independently arranged inside thewater storage tank 11, one end of theoverflow pipe 15 is in communication with thetoilet bowl 12, another end of theoverflow pipe 15 is fixed inside thewater storage tank 11. An opening at an end portion of the end, located inside thewater storage tank 11, of theoverflow pipe 15 is the overflow inlet, and the end, in communication with thetoilet bowl 12, of theoverflow pipe 15 is a water outlet. Theoverflow pipe 15 may be located inside the toilet body 1, or may also be located outside the toilet body 1. - It should be understood that, the spraying-type
water delivery pipe 14 and theoverflow pipe 15 are mutually independent, and are not in communication with each other. - The above embodiments in this specification are described in a progressive manner. Each of the embodiments is mainly focused on describing its differences from other embodiments, and references may be made among these embodiments with respect to the same or similar portions among these embodiments.
- Based on the above description of the disclosed embodiments, those skilled in the art are capable of carrying out or using the present application. It is obvious for those skilled in the art to make many modifications to these embodiments. The general principle defined herein may be applied to other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments illustrated herein, but should be defined by the broadest scope consistent with the principle and novel features disclosed herein.
- With the above arrangements, a pipeline pressure of the water intake device is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component, water is allowed to flow upward, therefore, the position of the bottom surface of the water storage tank can be effectively lowered. The position of the water inlet of the spraying-type water delivery pipe is lowered, which effectively reduces the height of the spraying-type water delivery pipe in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-type water delivery pipe is unchanged, a path length of the spraying-type water delivery pipe is decreased, which reduces the energy loss in the spraying-type water delivery pipe. When the flushing process is performed again, because the spraying-type water delivery pipe is filled with water, the water in the spraying-type water delivery pipe directly flushes the bottom of the toilet bowl through the water spray opening, an operation of discharging the air in the spraying-type water delivery pipe is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency. The bottom surface of the water storage tank is arranged to be lower than the surface of the toilet seat of the toilet bowl, so that under the condition that the water storage tank has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and
the production costs.
