DETAILED DESCRIPTION

[0023] The utility model provides a silent toilet. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] See also Figure 1-Figure 3 A 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 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 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 water inlet.

[0027] A water level sensor 8 is provided inside the water tank 1, and the water level sensor 8 is electrically connected to the driving mechanism 33 and the control valve 4. When the control valve 4 receives a signal that the water level is lower than the lowest position of the water level sensor 8, the control valve 4 is controlled to open to allow water to enter the water tank 1. The existing water level controller structure for toilets is an anti-siphon water inlet valve, which has a large height dimension, resulting in a large height of the water tank 1. The water level sensor of the present application can be a probe-type water level sensor or an infrared sensor, which detects the water level in the water tank 1 through the water level sensor 8, and controls the water inlet through the control valve 4 arranged outside the water tank 1, that is, only the water level sensor 8 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, and thus the volume of the water tank 1 can be designed to be smaller and the height lower.

[0028] 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.

[0029] Among them, the control valve 4 is connected to the water level sensor 8 by electrical signals, and the control valve 4 controls the on and off of the water inlet pipe 2 according to the electrical signal of the water level sensor 8, thereby realizing automatic water inlet. When the water level sensor 8 detects that the water level in the water tank 1 is lower than the set minimum water level, the control valve 4 opens to allow the water from the water source to enter the water tank. When the water level sensor 8 detects that the water level in the water tank 1 is higher than the set maximum water level, the control valve 4 closes to stop water inlet. Therefore, by setting the control valve 4 and the water level sensor 8, the automatic water inlet of the water tank 1 is realized to prepare for the user's next water use.

[0030] The silent toilet also includes a detector 6, which is used to detect whether someone is using or approaching. The detector 6 is connected to the flow regulating component 3 by electrical signals, and the flow regulating component 3 can control the water inlet speed from the water inlet pipe 2 to the water tank 1 according to the signal of the detector 6. When no one is using the toilet, the toilet uses the first water inlet speed for water inlet. When the radar of the toilet detects that the user is using the toilet and needs water inlet, the flow regulating component 3 automatically switches to the second water inlet speed for water inlet, and the first water inlet speed is lower than the second water inlet speed. Therefore, when no one is using the toilet, the first water inlet speed with a smaller flow rate is used for water inlet, which reduces the noise of water inlet and avoids affecting the user's rest. When the user is using the toilet and needs water inlet, the second water inlet speed with a larger flow rate is used for water inlet to ensure the user's water demand.

[0031] Among them, when no one is using the toilet, the electrical signal output by the detector 6 is the first signal, that is, the output code is "0"; when the detector 6 detects that the user is using the toilet, the electrical signal output by the detector 6 is the second signal, that is, the output code is "1".

[0032] In one embodiment, the detector 6 includes a radar 61, which is connected to the toilet body. When the radar 61 detects a person, it outputs a second signal; when the radar 61 does not detect a person, it outputs a first signal. The radar 61 can identify obstacles within a certain range around the toilet. That is, when a user approaches the toilet, the radar 61 can detect the direction and distance of the user. When it is detected that the user is in a set direction and a set distance, and the stay time exceeds a set time, it is determined that the user is using the toilet and the second signal is output. When no user is detected, the first signal is output.

[0033] For example: the radar 61 is set at the rear end of the toilet, and the detection direction is toward the front end. When an obstacle is detected in the 0-30° angle range in front of the toilet, and the distance between the obstacle and the radar does not exceed 1 meter, when the obstacle stays in the range for more than 3 seconds, it is determined that the user is using the toilet. When the obstacle stays in the range for no more than 3 seconds, it will not be determined that the user is using the toilet, avoiding the user passing by the toilet and determining that the user is using the toilet, thereby improving the accuracy of detection.

[0034] In one embodiment, the detector 6 includes a pressure sensor 62, which is disposed on the seat of the toilet. When the pressure sensor 62 detects that the pressure is greater than the set pressure value, the second signal is output; when the pressure sensor 62 detects that the pressure is less than the set pressure value, the first signal is output. The set pressure value is slightly greater than the pressure of the toilet cover. When the toilet cover is closed, since the pressure of the toilet cover is less than the set pressure value, it is not determined that the user is using the toilet. When the user sits on the toilet seat, the pressure detected by the pressure sensor 62 is greater than the set pressure value, so it is determined that the user is using the toilet.

[0035] In one embodiment, the detector 6 includes a radar 61 and a pressure sensor 62. When one of them outputs a second signal or both output a second signal, it is determined that the user is using the toilet. In this embodiment, by simultaneously providing the radar and the pressure sensor, when one of the radar and the pressure sensor fails, the toilet can still be used normally.

[0036] See also Figure 4 and Figure 5Specifically, 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 in 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.

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

[0039] 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 343 between the valve stem and the first water through hole 341 is reduced, 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 is reduced and enlarged, thereby increasing the flow rate of the incoming water. For another example, the regulating 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 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.

[0040] 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.

[0041] Implementation method 2 of flow regulating component 3:

[0042] See also Figure 4In 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.

[0043] 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.

[0044] See also Figure 4 In one embodiment, there is a gap 343 between the adjusting member 32 and the connecting member 31, and the water passage 34 also includes the gap 343. The cross-sectional area of ​​the gap 343 is smaller than the cross-sectional area of ​​the first water passage hole 341, so that when the adjusting member 32 rotates to a position where the second water passage hole 342 is completely misaligned with the first water passage hole 341, the water in the water inlet pipe 2 can still pass through the water passage 34 and enter the water tank 1.

[0045] In the above, when the second water-passing hole 342 is completely misaligned with the first water-passing 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-passing channel 34 is in the minimum state. When the regulating member 32 rotates to the position where the second water-passing hole 342 and the first water-passing 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-passing hole 342, so the water-passing channel 34 is in the maximum state.

[0046] In other embodiments, there is no gap 343 between the regulating member 32 and the connecting member 31, and in this embodiment, the control valve 4 may not be provided. That is, the detector 6 and the water level sensor are connected to the driving mechanism 33, and the flow regulating assembly 3 has at least three positions, which are a first position for water inlet at a first water inlet speed, a second position for water inlet at a second water inlet speed, and a third position in a closed state.

[0047] See also Figure 4 and Figure 5In one embodiment, 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 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 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.

[0048] 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.

[0049] In a smart toilet, a control chip (such as a single chip microcomputer) is usually provided inside, and the water level sensor 8, the detector 6, the control valve 4 and the driving mechanism 33 are all connected to the control chip to realize the electrical signal connection between the water level sensor 8, the detector 6, the control valve 4 and the driving mechanism 33. Among them, a control program is edited on the control chip, and then the automatic control of the water inlet of the toilet is realized by executing the control program through the control chip.

[0050] 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.
