Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and particularly relates to a flushing structure and a toilet bowl. Background Art

[0002] In the related art, the existing usage scenarios have imposed more tests on the flushing effect of toilets. Since the gravitational potential energy of the water contained in the water tank is relatively low and cannot meet the flushing requirements, some toilets use a water pump to increase the pressure of the water flow during flushing to meet the requirements. During use, the pressurized water and the water in the water tank are output together to meet the requirements for water pressure and water flow rate during the flushing process. However, the above toilets generally control the water tank and the pressurized water, and it is often impossible to synchronize when outputting the water flow, so that good water pressure and water flow rate cannot be achieved at the beginning. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a flushing structure, which can achieve better water pressure and water flow rate at the beginning of flushing when the flushing structure is applied to a toilet, and reduce the waste of water resources.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0043] Refer to Figures 1 to 5, an embodiment of the first aspect of the present application provides a flushing structure, including a flushing assembly 100 and a first valve assembly 200. Among them, the flushing assembly 100 includes a first pipeline 110 and a second pipeline 120. The first pipeline 110 is provided with a first channel 111, and the second pipeline 120 is provided with a second channel 121. The first channel 111 is communicated with the second channel 121. The first channel 111 is used to introduce water flow into the second channel 121 to increase the pressure and flow rate of the water flow in the second channel 121. The first valve assembly 200 includes a first movable member 211 and a first valve 220. The first valve 220 is accommodated in the water tank 710 and movably connected to one end of the second pipeline 120. The other end of the second pipeline 120 is used to connect to the toilet main body 700 so that the second channel 121 is communicated with the toilet bowl 720. The first movable member 211 is movably connected to the first pipeline 110. The first movable member 211 can drive the first valve 220 to move relative to the second pipeline 120 under the action of the liquid in the first pipeline 110, so that the second channel 121 is communicated with the water tank 710.

[0044] Referring to Figure 2 , when using the flushing structure, the pressure of the liquid introduced into the first channel 111 is greater than the pressure of the liquid in the water tank 710, which can push the first movable member 211 to move, so that the first valve 220 moves synchronously, and the water in the water tank 710 is introduced into the second channel 121. The first channel 111 is communicated with the second channel 121, so that the water flow with a higher pressure in the first channel 111 and the water in the water tank 710 are output from the end of the second channel 121 away from the first valve 220 into the toilet bowl 720 to complete the flushing. When the flushing structure starts to flush, the water flow can reach a better flow rate and flow velocity, which can accelerate the flushing speed of the toilet bowl 720 and reduce the waste of water resources. Among them, the high-pressure water flow introduced into the first channel 111 can come from the pressurized water flow in the water tank 710, or it can be the water flow provided by an external water source such as a water pipe. Since the water flow output from the second channel 121 to the toilet bowl 720 is used for flushing, the inner diameter of the second channel 121 will be designed to be larger. Therefore, when only using the water in the water tank to rely on gravitational potential energy to flow into the toilet bowl 720 through the second channel 121 for flushing, the dynamic pressure of the water flow is small, it is difficult to wash away too much dirt, and it is easy to get blocked. However, in the present application, the high-pressure water flow in the first channel 111 is combined with the water in the water tank 710 and output from the second channel 121 to the toilet bowl 720, which can provide a larger water flow rate and water pressure, achieve a better flushing effect and is not easy to cause blockage.

[0045] Specifically, a part of the first pipeline 110 is accommodated in the second channel 121. Since the water flow introduced into the first channel 111 comes from the pressurized water flow of the water tank 710 or an external water flow, the pressure of the liquid in the first channel 111 is greater than the pressure of the liquid in the water tank 710. And the flow rate of the water flow flowing from the first channel 111 into the second channel 121 is greater than the flow rate of the water flow flowing from the water tank 710 into the second channel. Due to the Venturi effect, the overall flow rate of the water flow ejected from the second channel 121 can be increased, thereby improving the flushing effect on the urinal 720.

[0046] Refer to Figure 2 , in some embodiments, the second pipeline 120 is provided with a first opening 122. The first opening 122 communicates the second channel 121 and the water tank 710. The first valve 220 is rotatably connected to the second pipeline 120 and corresponds to the first opening 122. The first movable assembly 210 is partially accommodated in the first channel 111. Specifically, the first movable assembly 210 further includes a telescopic member 212. The first pipeline 110 is further provided with a second opening 112. The second opening 112 communicates the first channel 111 and the water tank 710. The telescopic member 212 is connected to the first pipeline 110 and covers the second opening 112. The first movable member 211 is fixedly connected to the side of the telescopic member 212 facing the water tank 710. The telescopic member 212 can move relative to the second opening 112 under the pressure difference between the liquid in the first channel 111 and the liquid in the water tank 710. In this embodiment, the telescopic member 212 is selected as an airbag. The accommodation space provided by the airbag communicates with the water tank 710. When the pressure provided by the water flow introduced into the first channel 111 is greater than the pressure of the water in the water tank 710, the telescopic member 212 can be compressed to push the first movable member 211 to move to open the first opening 122. Conversely, under the pressure of the water in the water tank 710, the airbag is filled with water and the telescopic member 212 expands, driving the first movable member to move to close the first opening 122. In other embodiments, the telescopic member 212 can be selected as a spring. Then, when acted upon by the water pressure in the first channel 111, the spring will be compressed to drive the first valve 220 to move. And when there is no water pressure, the first movable member 211 will re-abut against the inner wall of the first pipeline 110 under the action of the spring.

[0047] Refer to Figure 2, when the first valve 220 is in the closed state, there is no water on the side of the first valve 220 facing the second channel 121, and buoyancy does not work. When the first valve 220 is lifted by the first movable member 211, there is water on both sides of the first valve 220. Under the action of buoyancy, the first movable member 211 drives the first valve 220 to quickly lift. When it is necessary to end the flushing, stopping the water supply to the first channel 111 will cause the first movable member 211 to retract into the first channel 111 under the pressure of the water in the water tank 710. The water below the first valve 220 will first flow away through the second channel 121, so that the first valve 220 quickly closes the first opening 122 under the combined action of its own weight and the water pressure above, separating the second channel 121 and the water tank 710.

[0048] Referring to Figure 2 , in some embodiments, the second pipeline 120 further includes an overflow channel 123. The overflow channel 123 communicates the water tank 710 and the second channel 121. The opening of the overflow channel 123 in the water tank 710 is higher than the highest liquid level position of the liquid in the water tank 710. When the first channel 111 and the water tank 710 inject water into the second channel 121, the gas in the second channel 121 can be discharged from the overflow channel 123, preventing the gas from staying in the second channel 121 and acting on the first valve 220, resulting in the first valve 220 being unable to correctly separate the water tank 710 and the second channel 121 when it is necessary to stop flushing.

[0049] Existing toilets need to use a cable to lift the corresponding valve to achieve drainage during power outage drainage. When assembling the toilet, it is necessary to add the assembly process between the corresponding valve and the cable, and the system complexity is also correspondingly increased. In addition, when performing power outage drainage operations on existing toilets, the action of lifting the corresponding valve is transmitted through a cable, and the operator needs to apply a relatively large pressing force, which will also affect the user experience.

[0050] Referring to Figures 3 to 5 , in some embodiments, the flushing structure further includes a second valve assembly 300. The second valve assembly 300 includes a second valve 310 and a second movable assembly 320. The second movable assembly 320 includes a second movable member 321 and a driving member 400. The second movable member 321 has a set first end 3211 and a second end 3212. The driving member 400 is connected to the first end 3211. An operating portion 3213 is provided at the second end 3212 for manual driving. The second movable member 321 is connected to the second valve 310. The second movable member 321 has a first state in which the first end 3211 is driven by the driving member 400 to switch the opening and closing of the second valve 310, and a second state in which the second end 3212 is driven to switch the opening and closing of the second valve 310.

[0051] When the second movable member 321 is in the first state, the second valve 310 can be connected and closed by driving the second movable member 321 to move through the driving member 400. Among them, the driving member 400 can be selected as a motor. When the second movable member 321 is in the second state, that is, when the driving member 400 cannot be used in the power failure state, the user can also manually drive the second movable member 321 to move to realize the connection or closing of the second valve 310. The above two states can both supply water to the first channel 111 without affecting the flushing function of the flushing structure.

[0052] In some embodiments, the driving member 400 includes a ratchet assembly. When the second movable member 321 is in the first state and the driving member 400 rotates in one direction, it can normally drive the second movable member 321 to rotate to realize the opening and closing of the second valve 310. When the second movable member 321 is in the second state and the second movable member 321 is manually driven to rotate, the motor does not move, and the ratchet assembly can realize tooth skipping, thus realizing the coaxial control of manual control and electric control.

[0053] Refer to Figure 3 , in some embodiments, the second valve 310 is provided with a water passing cavity 314. The second valve 310 is provided with a water inlet 311 and a water outlet 312. The water inlet 311 is used to connect to an external water source. The water passing cavity 314 communicates with the water inlet 311 and the water outlet 312. The second valve 310 further includes an adjusting member 315. The adjusting member 315 is accommodated in the water passing cavity 314. The adjusting member 315 is provided with a through hole 3151 penetrating in the thickness direction (refer to Figure 3 the left-right direction). The second valve 310 is further provided with a drain hole 313. The drain hole 313 communicates with the atmosphere. The drain hole 313 and the water outlet 312 are respectively arranged on both sides of the adjusting member 315. The adjusting member 315 can move relative to the water outlet 312 to divide the water passing cavity 314 into a first cavity 3141 and a second cavity 3142. The first cavity 3141 and the second cavity 3142 are respectively located at both ends of the thickness direction of the adjusting member 315. The first cavity 3141 communicates with the water inlet 311 and the water outlet 312. The second cavity 3142 communicates with the drain hole 313. Among them, when the drain hole 313 is opened, the water flow will be discharged from the drain hole 313 out of the water passing cavity 314. At this time, the pressure on the side of the adjusting member 315 facing the drain hole 313 decreases, while the pressure on the other side remains unchanged. Therefore, under the action of the water pressure, the adjusting member 315 will be driven to move, and a first cavity 3141 connecting the water inlet 311 and the water outlet 312 will be formed on the side of the adjusting member 315 facing the water outlet 312, so that the water flow can flow through the first cavity 3141. When the drain hole 313 is closed, the water flow can enter the second cavity 3142 through the through hole 3151 in the thickness direction of the adjusting member 315, so that the water pressure in the second cavity 3142 increases and drives the adjusting member 315 to move towards the water outlet 312 to close the water inlet 311 and the water outlet 312.

[0054] Thus, the above-mentioned water outlet structure can achieve the connection between the second valve 310 and the first valve 220 even in a power-off state, so that the water flow during flushing comes from the water in the water tank 710 and the water from an external water source. While ensuring the water volume, it can have a certain flushing pressure on the toilet 720, improving the flushing effect. It can be understood that when the drain hole 313 corresponds to the water tank 710 and the water flow flows out from the drain hole 313, the water flow can flow into the water tank 710 and be reused, preventing water splashing and reducing water resource waste at the same time.

[0055] Specifically, the water inlet 311 and the water outlet 312 are arranged at intervals along the water flow direction and are both arranged facing the drain hole 313. The adjusting member 315 can abut against the inner wall of the second valve 310 on the side close to the water outlet 312 to separate the water inlet 311 from the water outlet 312, and move to abut against the inner wall of the second valve 310 on the side close to the drain hole 313 to connect the water inlet 311 and the water outlet 312.

[0056] The adjusting member 315 can be movable relative to the water passing cavity 314 in at least the following two ways. The adjusting member 315 can be slidably connected to the cavity wall of the water passing cavity 314. The adjusting member 315 is made of a material with relatively high rigidity and can move relative to the water outlet 312 under the action of water pressure to separate the water passing cavity 314 to form a first cavity 3141 for connecting the water inlet 311 and the water outlet 312. Conversely, after closing the drain hole 313, the adjusting member 315 can also separate the water inlet 311 and the water outlet 312 under the action of water pressure. Or, the adjusting member 315 is made of a deformable material such as a deformable membrane. The adjusting member 315 is directly fixedly connected to the second valve 310 and separates the water inlet 311 and the water outlet 312. Under the action of water pressure, the adjusting member 315 can deform to separate the water passing cavity 314 into a first cavity 3141 and a second cavity 3142. Conversely, after closing the drain hole 313, the adjusting member 315 can also return to its original state under the action of water pressure to re-separate the water inlet 311 and the water outlet 312.

[0057] Refer to Figure 4 and Figure 5, in some embodiments, the second movable component 320 further includes a blocking member 322 disposed between the second movable member 321 and the second valve 310. The blocking member 322 is provided with a blocking portion 3221 corresponding to the drain hole 313. The second movable member 321 can drive the blocking member 322 to move, and the blocking portion 3221 can move relative to the second valve 310 to block or open the drain hole 313. Among them, the blocking portion 3221 is generally spherical and has a diameter larger than the aperture of the drain hole 313. The blocking portion 3221 can be made of a deformable material such as latex. When blocking the drain hole 313, it can abut against the second valve 310 and deform to block the drain hole 313, having good sealing performance.

[0058] Further, an adjusting portion 3222 is provided on a side of the blocking member 322 facing away from the blocking portion 3221. The adjusting portion 3222 abuts against the outer periphery of the second movable member 321. At least one groove 3216 is provided on the second movable member 321 in the circumferential direction. When the adjusting portion 3222 rotates to correspond to the groove 3216, the blocking member 322 will swing relative to the second valve 310 under the action of gravity, and the adjusting portion 3222 will be received in the groove 3216, so that the blocking portion 3221 opens the drain hole 313. Since the first end 3211 and the second end 3212 of the second movable member 321 are respectively connected to the driving member 400 and for manual driving use.

[0059] When the second movable member 321 is in the first state, the driving member 400 can drive the second movable member 321 to rotate to supply water to the first channel 111, and the driving member 400 can be driven by a set computer program to make the adjusting portion 3222 stay in the groove 3216 for a set time to meet the water supply volume to the first channel 111. When the second movable member 321 is in the second state, the second movable member 321 can be manually driven to rotate to make the adjusting portion 3222 rotate to be received in the groove 3216. The operator can control the duration of the adjusting portion 3222 received in the groove 3216 to adaptively control the flushing duration. After the flushing is completed, the adjusting portion 3222 is moved out of the groove 3216 to make the blocking portion 3221 re-close the drain hole 313.

[0060] Specifically, the second movable member 321 is generally cylindrical, and the groove 3216 is smoothly transitioned with the rest of the outer wall surface of the second movable member 321, so that the adjusting portion 3222 can slide into and out of the groove 3216 more smoothly.
