[0027] The current water inlet method for smart toilets is fixed flow. If the pipe network pressure is high, the water inlet flow will be large, and the noise will also increase, which will affect sleep in the middle of the 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 silent toilet with adjustable water inlet. Figure 1-Figure 3 The adjustable water inlet silent 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 interior of the water tank 1 through the water inlet pipe 2. The flow regulating component 3 is connected to the water inlet pipe 2 and is connected to the water tank 1. The flow regulating component 3 can adjust the water flow from the water inlet pipe 2 into the interior of the water tank 1, thereby adjusting the noise of the water inlet.

[0028] The adjustable water inlet silent toilet also includes a clock module 5, which is electrically connected to the flow regulating component 3. The flow regulating component 3 can control the water flow from the water inlet pipe 2 into the water tank 1 according to the signal output by the clock module 5. 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 of water from the water inlet pipe 2 into the water tank 1, 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 of water from the water inlet pipe 2 into the water tank 1 to ensure the water demand of the toilet.

[0029] Specifically, 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.

[0030] The clock module 5 is connected to the driving mechanism 33 by electrical signals. The clock module 5 stores a relationship table between the water inlet time and the water inlet speed. The water inlet speed is obtained by the water inlet time signal of the clock module 5. The driving mechanism 33 can adjust the size of the water passage 34 according to the water inlet speed. The size of the water passage 34 corresponds to the water inlet speed, that is, the larger the water passage 34, the faster the water inlet speed.

[0031] For example, the drive mechanism 33 can automatically adjust the size of the water passage 34 according to the input time signal, that is, the relationship table between the water inlet time and the water inlet speed corresponds to multiple time periods, and the water inlet speed corresponding to each time period is different. When the clock module 5 triggers the signal to enter the corresponding time period, the drive mechanism 33 drives the adjustment member 32 to move and adjusts the water passage 34 to a size corresponding to the water inlet flow rate. For example, a small flow rate is set to be used for water inlet from 10 pm to 7 am, and a large flow rate is used for water inlet in the remaining 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.

[0032] For example, the clock module 5 is RX8803SA, RX-4803SA or RX-8900CE.

[0033] Specifically, the driving mechanism is fixed on the outside of the water tank, and the connecting member and the adjusting member are connected on the top of the water tank, so that the space occupied by the flow regulating component 3 inside the water tank is reduced, thereby making the water tank smaller and reducing costs.

[0034] 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 .

[0035] Implementation method 1 of the flow regulating component 3:

[0036] See also Figure 5 , the movement of the regulating member 32 relative to the connecting member 31 is a linear movement, for example: the regulating 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 between the valve stem and the first water through hole 341 decreases, thereby reducing the flow rate of water inlet. On the contrary, when the driving mechanism 33 drives the valve stem away from the first water through hole 341, the gap between the valve stem and the first water through hole 341 decreases and increases, thereby increasing the flow rate of water inlet. For another example, the regulating member 32 is a valve, and the direction of 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 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. Among them, the water outlet 344 of the water passage 34 can be set on the connecting member 31.

[0037] 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.

[0038] Implementation method 2 of flow regulating component 3:

[0039] See also Figure 4 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 disposed inside the connecting member 31 and forms a ball valve core. When the ball valve core rotates, the area of ​​the first water through hole 341 blocked by the valve can be adjusted, thereby changing the flow rate of water flowing out of the first water through hole 341.

[0040] 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 achieving control of different water inlet speeds.

[0041] In the embodiment where the movement of the adjusting member 32 relative to the connecting member 31 is a rotational movement, the water passage 34 further includes a second water passage hole 342 disposed on the adjusting member 32, the second water passage hole 342 corresponds to the position of the first water passage hole 341, and when the adjusting member 32 moves relative to the connecting member 31, the overlap area between the second water passage hole 342 and the first water passage hole 341 can be changed. In other embodiments, the second water passage 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 passage hole 341.

[0042] In a preferred embodiment of the present application, the surface on which the first water through hole 341 is arranged on the connecting member 31 is the first surface, and the surface on which the second water through hole 342 is arranged on the adjusting member 32 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, 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, the inner wall surface of the adjusting member 32 is the second surface, and a groove is provided on the inner wall of the adjusting member 32, and the groove forms the 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] In 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 interior of the water tank 1.

[0045] 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.

[0046] 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.

[0047] In one embodiment, the angle when the second water through hole 342 and the first water through hole 341 are completely overlapped or completely misaligned is 0°, and the water inlet time and noise level corresponding to the different angles of the adjustment member 32 are obtained by experiment or calculation. When in use, the frequency of use of the user in each time period is recorded, and the water inlet speed is adjusted according to the frequency of use of the user. For example, the angle when the second water through hole 342 and the first water through hole 341 are completely misaligned is 0°, and the angle when the second water through hole 342 and the first water through hole 341 are completely overlapped is 30°. It takes 30 minutes to fill the water tank with water at the minimum water inlet speed, and it takes 2 minutes to fill the water tank with water at the maximum water inlet speed. According to statistics, the frequency of users using the toilet in a certain period of time is about 14 minutes / time. Therefore, during this period of time, the adjustment member 32 is adjusted to a position where the angle between the second water through hole 342 and the first water through hole 341 is 15°, so that the water inlet demand within this period of time can be guaranteed and the water inlet noise can be reduced.

[0048] The water outlet 344 of the water passage 34 is arranged on the regulating member 32, so that the water of the water inlet pipe 2 reaches the inside of the water tank 1 after passing through the water passage 34 and the water outlet 344. Among them, 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 component 3, which reduces the use of parts and reduces the cost. 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 reverse into the water inlet pipe 2. In order to solve the problem that the water in the water tank 1 will reverse into the water inlet pipe 2, an anti-siphon valve is usually set 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 to prevent 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 negative pressure occurs in the water inlet pipe 2, the outside air enters the water inlet pipe 2, thereby solving the problem of water backflow in the water tank 1, and no anti-siphon valve is required, thereby reducing costs. In other embodiments, the water outlet 344 can also be set on the connecting member 31.

[0049] Preferably, a noise reduction head is installed on the water outlet 344, which can reduce the impact of water, thereby reducing the noise when water enters the water tank 1. Specifically, the noise reduction head has a buffer material, such as sponge or cloth, so that when water passes through the noise reduction head, the buffer material reduces the impact of water, thereby reducing noise.

[0050] A water level sensor 7 is provided inside the water tank 1 , and the water level sensor is electrically connected to the driving mechanism 33 and the control valve 4 . When the control valve 4 receives a signal that the water surface is lower than the lowest position of the water level sensor 7 , the control valve 4 is controlled to open to allow water to enter the water tank 1 .

[0051] 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 water level sensor 7 of the present application may be a probe-type water level sensor or an infrared sensor, which detects the water level in the water tank 1 and controls the water inlet through the control valve 4 disposed outside the water tank 1, that is, only the water level sensor 7 needs to be disposed in the water tank 1, thereby reducing the space in the water tank 1 for installing the water level controller structure, thereby enabling the water tank 1 to be designed to be smaller in volume and lower in height.

[0052] In one embodiment, the clock module 5 includes a signal processing circuit board and a clock chip, and the clock chip, the water level sensor 7, the control valve 4 and the driving mechanism 33 are all connected to the signal processing circuit board to realize the electrical signal connection between the clock module 5, the water level sensor 7, the control valve 4 and the driving mechanism 33. Among them, a control program is edited on the signal processing circuit board, and then the control chip executes the control program to realize the automatic control of the water inlet of the toilet.

[0053] 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.
