[0030] Embodiment 1:

[0031] The current water inlet method for smart toilets is fixed flow. If the pipe network pressure is high, the water flow will be large, and the noise will also increase, which will affect sleep late at night. In order to solve the problem that the sound of toilet water inlet is affected by the water pressure of the water inlet pipe network, this application provides a toilet with adjustable water inlet. Figure 2 and Figure 3The adjustable water inlet toilet includes a water tank 1, a water inlet pipe 2 and a flow regulating component 3. The water tank 1 is used to store water for cleaning the toilet. The water inlet pipe 2 is connected to an external water source. Water from the external water source can enter the water tank 1 through the water inlet pipe 2. The flow regulating component 3 is connected to the water inlet pipe 2 and communicates with the interior of the water tank 1. The flow regulating component 3 can adjust the flow of water entering the water tank 1 from the water inlet pipe 2, thereby adjusting the noise of the water inlet.

[0032] Among them, when the water pressure of the water inlet pipe 2 is high, the flow rate of water entering the water tank 1 from the water inlet pipe 2 is reduced through the flow regulating component 3, that is, a small flow of water is inflowed, thereby reducing the noise. When rapid water inflow is required, the flow regulating component 3 increases the flow rate of water entering the water tank 1 from the water inlet pipe 2, so as to meet the needs of different scenarios. For example, when the toilet is in a time period with low frequency of use, such as at night, the flow regulating component 3 reduces the flow rate of water entering the water tank 1 from the water inlet pipe 2, thereby reducing noise and avoiding affecting the user's rest. When the toilet is in a time period with high frequency of use, such as during the day, the flow regulating component 3 increases the flow rate of water entering the water tank 1 from the water inlet pipe 2 to ensure the water demand of the toilet.

[0033] See also Figures 4 to 9 The flow regulating assembly 3 includes a connecting member 31, a regulating member 32 and a driving mechanism 33. The connecting member 31 is connected to the water inlet pipe 2. The regulating member 32 is movably connected to the connecting member 31. A water passage 34 is formed between the connecting member 31 and the regulating member 32. The water passage 34 connects the water inlet pipe 2 and the water tank 1, so that water from the water source can pass through the water inlet pipe 2 and the water passage 34 to reach the inside of the water tank 1 to replenish the water of the water tank 1. The driving mechanism 33 is connected to the regulating member 32 and can drive the regulating member 32 to move so as to adjust the size of the water passage 34.

[0034] In one embodiment, a water pressure detector can be provided in the water inlet pipe 2, and the flow regulating component 3 controls the water inlet speed according to the water pressure detected by the water pressure detector, so that less noise is generated during water inlet to avoid affecting the user's sleep.

[0035] In one embodiment, the flow regulating component 3 can also control different water inlet speeds according to different time periods. For example, a small water flow rate is used from 10 pm to 7 am, and a large water flow rate is used for the rest of the time periods. Whenever the set time period is reached, the corresponding time signal is automatically triggered and automatically switched to the corresponding water inlet flow rate.

[0036] In one embodiment, the drive mechanism 33 can automatically adjust the size of the water passage 34 according to the input usage signal. For example, the toilet is set to a low-flow water inlet mode by default. When the toilet radar detects that the user is using the toilet and needs water inlet, the drive mechanism 33 automatically switches to a high-flow water inlet state.

[0037] Specifically, the water passage 34 includes a first water passage hole 341 provided on the connecting member 31 . When the adjusting member 32 moves relative to the connecting member 31 , it can cover the first water passage hole 341 , thereby adjusting the size of the water passage 34 .

[0038] See also Fig. 9 In one embodiment, the movement of the adjusting member 32 relative to the connecting member 31 is a linear movement. For example, the adjusting member 32 is a valve stem, and the movement of the valve stem is in the direction of approaching or moving away from the first water through hole 341. When the driving mechanism 33 drives the valve stem to approach the first water through hole 341, the gap 343 between the valve stem and the first water through hole 341 decreases, thereby reducing the flow rate of the incoming water. On the contrary, when the driving mechanism 33 drives the valve stem away from the first water through hole 341, the gap 343 between the valve stem and the first water through hole 341 decreases and increases, thereby increasing the flow rate of the incoming water. For another example, the adjusting member 32 is a valve, and the direction of the valve movement is the radial direction of the first water through hole 341. When the driving mechanism 33 drives the valve to move, the area of ​​the valve blocking the first water through hole 341 can be adjusted, thereby changing the flow rate of water flowing out of the first water through hole 341.

[0039] In this embodiment, the driving mechanism 33 is an electric telescopic rod, or the driving mechanism 33 includes a motor 331, a gear 332 and a rack 333. The motor 331 is fixed to the outer surface of the water tank 1, the gear 332 is fixed to the rotating shaft of the motor 331, and the rack 333 is fixed to the adjusting member 32 and meshes with the gear 332, so that the motor 331 can drive the adjusting member 32 to move linearly. Among them, the motor 331, as an action actuator, can control the position of the adjusting member 32 relative to the connecting member 31 by controlling the rotation angle of the rotating shaft of the motor 331, thereby realizing the control of different water inlet speeds.

[0040] See also Figure 5 and Figure 8 In one embodiment, the movement of the adjusting member 32 relative to the connecting member 31 is a rotational movement. For example, the adjusting member 32 is arranged inside the connecting member 31 and forms a ball valve core. When the ball valve core rotates, the area of ​​the valve covering the first water through hole 341 can be adjusted, thereby changing the flow rate of water flowing out of the first water through hole 341. In this embodiment, the driving mechanism 33 is a motor 331, and the position of the adjusting member 32 relative to the connecting member 31 can be controlled by controlling the rotation angle of the rotating shaft of the motor 331, thereby realizing the control of different water inlet speeds.

[0041] In one embodiment, the water passage 34 further includes a second water through hole 342 disposed on the adjusting member 32, the second water through hole 342 corresponds to the position of the first water through hole 341, and when the adjusting member 32 moves relative to the connecting member 31, the overlap area between the second water through hole 342 and the first water through hole 341 can be changed. In other embodiments, the second water through hole 342 may not be disposed on the adjusting member 32, but the size of the water passage 34 is formed by the outer side wall of the adjusting member 32 and the first water through hole 341.

[0042] In a preferred embodiment of the present application, the connecting member 31 and the adjusting member 32 are rotatably connected, the surface of the connecting member 31 on which the first water through hole 341 is arranged is the first surface, and the surface of the adjusting member 32 on which the second water through hole 342 is arranged is the second surface, the second surface is opposite to the first surface, and when the adjusting member 32 is rotated, the overlapping area between the first water through hole 341 and the second water through hole 342 changes.

[0043] For example, see Figure 5 The connecting member 31 and the adjusting member 32 are both pipe fittings. The adjusting member 32 is sleeved on the end of the connecting member 31 away from the water inlet pipe 2. The circumferential outer surface of the connecting member 31 is the first surface, and the inner wall surface of the adjusting member 32 is the second surface. A groove is provided on the inner wall of the adjusting member 32, and the groove forms a second water through hole 342. When the driving mechanism 33 drives the adjusting member 32 to rotate relative to the axis of the connecting member 31, the position of the second water through hole 342 relative to the first water through hole 341 changes, so that the second water through hole 342 and the first water through hole 341 are overlapped or misaligned, thereby adjusting the flow rate entering the water tank 1.

[0044] For example, see Figure 8 The connecting member 31 and the adjusting member 32 are both pipe fittings, the end surface of the connecting member 31 close to one end of the adjusting member 32 is the first surface, the first water through hole 341 is arranged at a position deviated from the axis of the connecting member 31, the end surface of the adjusting member 32 close to one end of the connecting member 31 is the second surface, and the second water through hole 342 is arranged at a position deviated from the axis of the adjusting member 32, so that when the driving mechanism 33 drives the adjusting member 32 to rotate relative to the axis of the connecting member 31, the position of the second water through hole 342 relative to the first water through hole 341 changes, so that the second water through hole 342 and the first water through hole 341 overlap or are misaligned, thereby adjusting the flow rate entering the water tank 1.

[0045] See also Figure 4 , Figure 5 and Figure 8In one embodiment, there is a gap 343 between the second surface and the first surface, the gap 343 connects the first water through hole 341 and the second water through hole 342, the water passage 34 also includes the gap 343, and the cross-sectional area of ​​the gap 343 is smaller than the cross-sectional area of ​​the first water through hole 341, so that when the adjusting member 32 rotates to a position where the second water through hole 342 is completely misaligned with the first water through hole 341, the water in the water inlet pipe 2 can still pass through the water passage 34 and enter the water tank 1.

[0046] In the above, when the second water through hole 342 is completely misaligned with the first water through hole 341, the cross-sectional area of ​​water flowing through the flow regulating component 3 is only the cross-sectional area of ​​the gap 343, so the water passage 34 is in the minimum state. When the regulating member 32 rotates to the position where the second water through hole 342 and the first water through hole 341 completely overlap, the cross-sectional area of ​​water flowing through the flow regulating component 3 is the sum of the cross-sectional area of ​​the gap 343 and the cross-sectional area of ​​the second water through hole 342, so the water passage 34 is in the maximum state. When the second water through hole 342 partially overlaps with the first water through hole 341, the water passage 34 is between the minimum state and the maximum state.

[0047] The water inlet pipe 2 is provided with a control valve 4, which can control the on and off of the water inlet pipe 2. When the water tank 1 needs to take in water, the control valve 4 is opened, so that the water from the water source passes through the water inlet pipe 2 and the flow regulating component 3 to enter the water tank 1. When the water tank 1 does not need to take in water, the control valve 4 is closed, so that the water from the water source cannot pass through the water inlet pipe 2 and the flow regulating component 3 to enter the water tank 1.

[0048] In other embodiments, the second surface is completely fitted with the first surface, so that when the second water through hole 342 is completely misaligned with the first water through hole 341, water in the water inlet pipe 2 cannot enter the water tank 1. In this embodiment, the control valve 4 may not be provided.

[0049] In the above, the water tank 1 has at least one water storage cavity, and the water outlet 344 of the water passage 34 faces at least one water storage cavity inside the water tank 1. The water outlet 344 of the water passage 34 can be set on the adjusting member 32 or on the connecting member 31.

[0050] Embodiment 2:

[0051] See also Figure 2 and Figure 3The difference between the second embodiment and the first embodiment is that the water tank 1 has two water storage cavities, that is, the water tank 1 includes a first water tank 12 and a second water tank 13, and the water outlet 344 of the water passage 34 is arranged on the adjusting member 32, and the connecting member 31 and the adjusting member 32 are rotatably connected, so that when the size of the water passage 34 is adjusted, the position of the water outlet 344 can be adjusted at the same time, so that water can be supplied to the two water tanks 1.

[0052] Specifically, a middle partition 11 is provided inside the water tank 1, and the middle partition 11 divides the water tank 1 into a first water tank 12 and a second water tank 13. In a smart toilet with flushing and jet cleaning functions, there are usually two water tanks 1, one water tank 1 (i.e., the first water tank 12) stores water required for flushing the toilet, and the other water tank 1 (i.e., the second water tank 13) stores water required for jet cleaning. The water consumption of the flushing function is greater than that of the jet cleaning function, so the volume of the first water tank 12 is greater than that of the second water tank 13.

[0053] The water passage 34 also includes a water outlet 344 arranged on the adjusting member 32, and the water outlet 344 is arranged along the radial direction of the adjusting member 32. When the adjusting member 32 is in a position where the second water through hole 342 coincides with the first water through hole 341, the water outlet 344 faces the first water tank 12. When the adjusting member 32 is in a position where the second water through hole 342 and the first water through hole 341 are misaligned, the water outlet 344 faces the second water tank 13 to ensure the water inlet speed of the first water tank 12 and the second water tank 13.

[0054] In which, during the process of the second water through hole 342 being adjusted from a position completely overlapping with the first water through hole 341 to a position completely misaligned with the first water through hole 341, that is, when the second water through hole 342 partially overlaps with the first water through hole 341, the water outlet 344 can always be directed toward the first water tank 12; or, when the second water through hole 342 mostly overlaps with the first water through hole 341, the water outlet 344 is directed toward the first water tank 12, and when the second water through hole 342 partially overlaps with the first water through hole 341, the water outlet 344 is directed toward the second water tank 13.

[0055] In a preferred embodiment of the present application, when the water passage 34 is in the minimum state, the water inlet speed of the second water tank 13 can be guaranteed, and the water outlet 344 is toward the second water tank 13. When the second water through hole 342 overlaps with the first water through hole 341 (including partial overlap and complete overlap), the water outlet 344 is toward the first water tank 12, thereby realizing the adjustment of the water inlet flow rate of the first water tank 12.

[0056] Embodiment three:

[0057] Embodiment 3 is based on Embodiment 1 or Embodiment 2, and the water outlet 344 is separated from the water surface of the water tank 1 , so that when negative pressure occurs in the water inlet pipe 2 , the water inside the water tank 1 will not flow back into the water inlet pipe 2 .

[0058] See also Figure 2 and Figure 3 , the water outlet 344 is arranged at the upper part of the water tank 1 and is separated from the water surface of the water tank 1, so it is not necessary to set an anti-siphon valve on the water inlet pipe 2 or the flow regulating assembly 3, thereby reducing the use of parts and reducing costs. Among them, the existing toilet water inlet pipe 2 usually extends to the bottom of the water tank 1. When the water inlet pipe 2 has a negative pressure, the water in the water tank 1 will reversely enter the water inlet pipe 2. In order to solve the problem that the water in the water tank 1 will reversely enter the water inlet pipe 2, an anti-siphon valve is usually arranged on the water inlet pipe 2. When the water inlet pipe 2 has a negative pressure, the air inlet of the anti-siphon valve connected to the outside is opened, so that the outside air enters the water inlet pipe 2, thereby preventing the water in the water tank 1 from flowing back. In this embodiment, by separating the water outlet 344 from the water surface of the water tank 1, when the water inlet pipe 2 has a negative pressure, the outside air enters the water inlet pipe 2, thereby solving the problem of water backflow in the water tank 1, and it is not necessary to set an anti-siphon valve, thereby reducing costs.

[0059] Preferably, a noise reduction head 5 is installed on the water outlet 344, and the noise reduction head 5 can reduce the impact of water, thereby reducing the noise when water enters the water tank 1. Specifically, the noise reduction head 5 has a buffer material inside, such as sponge or cloth, so that when water passes through the noise reduction head 5, the buffer material reduces the impact of water, thereby reducing noise.

[0060] In one embodiment, an anti-spoiler baffle 14 is provided in the water tank 1, and the anti-spoiler baffle 14 divides the inside of the water tank 1 into a first cavity and a second cavity. A third water through hole 141 is provided at the lower part of the anti-spoiler baffle 14, and the third water through hole 141 communicates with the first cavity and the second cavity. The first cavity is communicated with the water passage 34, and a pipe interface 15 is provided at the bottom of the water tank 1 and located in the second cavity. Among them, by providing the anti-spoiler baffle 14 in the water tank 1, the water surface fluctuation in the water tank 1 can be reduced, so that when the flushing function or the jet cleaning function is used, the water surface is always in a state of covering the pipe interface 15, and air enters the sewage pipe or the nozzle to affect the use effect, and the noise generated by the water surface fluctuation can also be reduced.

[0061] For example, when the anti-spoiler baffle 14 is disposed in the second water tank 13, the pipe interface 15 is connected to the booster pump and the nozzle through a pipe, and the anti-spoiler baffle 14 slows down the fluctuation of the water surface, so as to prevent the water surface from being lower than the pipe interface 15 and causing air to enter the pipe, thereby affecting the effect of the water sprayed from the nozzle. In other embodiments, the anti-spoiler baffle 14 may be disposed in the first water tank 12, or both the first water tank 12 and the second water tank 13 may be provided with the anti-spoiler baffle 14.

[0062] See also Figure 1 A box cover 7 is fixed on the top surface of the water tank 1, which covers the top of the water tank 1 and surrounds the water outlet 344 inside the water tank 1. The arrangement of the box cover 7 can prevent dust from entering the water tank 1 and reduce the transmission of water inlet noise inside the water tank 1 to the outside. The box cover 7 is connected to the water tank 1 by buckling or fixed by screws.

[0063] Embodiment 4:

[0064] Embodiment 4 Based on Embodiment 1, Embodiment 2 or Embodiment 3, a water level sensor is arranged inside the water tank 1 to realize automatic water inflow and to lower the height of the water tank 1 .

[0065] See also Figure 2 and Figure 3 Specifically, a water level sensor (not shown in the figure) is provided inside the water tank 1, and the water level sensor is connected to the driving mechanism 33 and the control valve 4 by electrical signals. When the control valve 4 receives that the water surface is lower than the lowest position of the water level sensor, the control valve 4 is controlled to open so that water can enter the water tank 1. Specifically, in the embodiment where the water tank 1 includes a first water tank 12 and a second water tank 13, water level sensors are provided inside the first water tank 12 and the second water tank 13. When the water level sensor in the first water tank 12 detects that water needs to enter, the driving mechanism 33 drives the water outlet 344 toward the first water tank 12 and controls the valve 4 to open, so that water can be added to the first water tank 12. When the water level sensor in the second water tank 13 detects that water needs to enter, the driving mechanism 33 drives the water outlet 344 toward the second water tank 13 and controls the valve 4 to open, so that water can be added to the second water tank 13.

[0066] The existing toilet water level controller structure is an anti-siphon water inlet valve, which has a large height dimension, thus resulting in a large height of the water tank 1. The present application detects the water level in the water tank 1 through a water level sensor, and controls the water inlet through a control valve 4 arranged outside the water tank 1, that is, only the water level sensor needs to be arranged in the water tank 1, thereby reducing the space in the water tank 1 for installing the water level controller structure, thereby being able to design the volume of the water tank 1 to be smaller and the height to be lower.

[0067] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
