DETAILED DESCRIPTION

[0020] The utility model provides a water channel structure of a 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.

[0021] 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.

[0022] 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.

[0023] Some existing smart toilets have a spray function. Since the water in the spray function needs to contact the user's skin, when the water quality is poor, it not only fails to achieve a cleaning effect, but also causes bacteria in the water to attach to the user's skin, affecting the user's health. Among them, the water outlet of the spray gun is relatively small to increase the water outlet pressure. When the water quality is poor, impurities in the water can easily cause the water outlet of the spray gun to be blocked.

[0024] See also Figure 1The present application provides a water circuit structure of a toilet, including a cleaning water tank 1, a water quality detection module 3, a control mechanism 4, a water passage 5 and a spray gun 2. The water quality detection module 3 is arranged inside the cleaning water tank 1 to detect the quality information of the cleaning water; the control mechanism 4 is connected to the cleaning water tank 1, and the water passage 5 connects the cleaning water tank 1 and the spray gun 2, so that the water inside the cleaning water tank 1 can flow to the spray gun 2 through the water passage 5. The control mechanism 4 is connected to the water passage 5. When the water quality is poor, the control mechanism controls the flow direction of the water in the water passage to avoid the blockage of the spray gun caused by the water of poor quality passing through the spray gun, and also avoids the use of water of poor quality for cleaning to affect the health of the user.

[0025] In one embodiment, the water quality detection module 3 is electrically connected to the control mechanism 4 , and the control mechanism 4 can control the on-off of the water pipeline 5 according to the quality information of the cleaning water, thereby realizing automatic control of the water pipeline 5 .

[0026] Furthermore, the water pipeline 5 includes a first water pipeline 51 and a second water pipeline 52, and the first water pipeline 51 and the second water pipeline 52 are both connected to the control mechanism 4. The control mechanism 4 can control the on-off of the first water pipeline 51 and the on-off of the second water pipeline 52, that is, the control mechanism 4 can switch to a state where the cleaning water tank 1 is connected to the first water pipeline or the cleaning water tank 1 is connected to the second water pipeline, and a filter 6 is connected in series on the first water pipeline 51.

[0027] When the water quality detection module 3 detects that the water quality is poor, the control mechanism 4 controls the water to flow to the spray gun 2 through the first water pipeline 51, so that the filter 6 can filter the water to meet the cleanliness requirements of the spray water, thereby avoiding pipeline blockage and affecting the health of the user. When the water quality detection module 3 detects that the water quality is good, the control mechanism 4 controls the water to flow to the spray gun 2 through the second water pipeline 52, reducing the frequency of use of the filter 6 and reducing maintenance costs. In addition, by connecting the filter 6 in series to the first water pipeline 51, the spray function of the toilet can still be used when the water quality is poor.

[0028] In other embodiments, when the water quality detection module 3 detects that the water quality is poor, the control mechanism 4 controls the water to be discharged into the flushing water tank to prevent the poor quality water from passing through the spray gun and causing the spray gun to be blocked.

[0029] Among them, the water from the water source will enter the cleaning water tank 1 in advance to prepare for the next use of the toilet. When the water quality is poor, some impurities in the water will settle to the bottom. Therefore, the water quality detection module 3 is set at the lower end of the cleaning water tank 1 to make the detection effect more accurate. Preferably, the lower end of the cleaning water tank 1 is provided with a water tank outlet for connecting the water pipeline 5, and the water quality detection module 3 and the water tank outlet of the cleaning water tank 1 are set at the same height, so that the water quality detection module 3 detects the water delivered to the spray gun 2.

[0030] In one embodiment, the water quality detection module 3 includes one or more of a conductivity sensor and a turbidity sensor. When the water quality deteriorates, the conductivity of the water will increase, and the water quality can be detected by the conductivity sensor. When the water quality deteriorates, the suspended particles in the water will increase, and the water quality can also be detected by the turbidity sensor. Among them, in the embodiment where the water quality detection module 3 includes a conductivity sensor and a turbidity sensor, as long as one of them detects that the water quality has deteriorated and reaches a level that requires filtration, the control mechanism 4 controls the first water pipeline 51 to be connected to the cleaning water tank 1. When the conductivity sensor and the turbidity sensor detect that the water quality reaches the requirement that filtration is not required, the control mechanism 4 controls the second water pipeline 52 to be connected to the cleaning water tank 1.

[0031] See also Figure 2 and Figure 3 In one embodiment, the control mechanism 4 includes a connecting member 41 and a control member 42, the connecting member 41 is connected to the cleaning water tank 1, the first water pipeline 51 and the second water pipeline 52 are connected to the connecting member 41, the control member 42 is movably connected to the connecting member 41, and can control the opening and closing of the first water pipeline 51 and the second water pipeline 52, thereby realizing the switching between the first water pipeline 51 being connected to the cleaning water tank 1 and the second water pipeline 52 being connected to the cleaning water tank 1.

[0032] Specifically, the connecting member 41 is provided with a water inlet 411, a first water outlet 412 and a second water outlet 413, the water inlet 411 is connected to the cleaning water tank 1, the first water pipeline 51 is connected to the first water outlet 412, and the second water pipeline 52 is connected to the second water outlet 413, so as to realize the connection between the first water pipeline 51 and the second water pipeline 52 and the control mechanism 4. The control member 42 can control the first water outlet 412 to be connected to the water inlet 411 or the second water outlet 413 to be connected to the water inlet 411.

[0033] Among them, the connecting member 41 is provided with an inner cavity 414, and the water inlet 411, the first water outlet 412 and the second water outlet 413 are all connected to the inner cavity 414, and the control member 42 includes a driving mechanism 421 and a valve core 422, the valve core 422 is movably arranged in the inner cavity 414, the driving mechanism 421 is connected to the valve core 422, and can drive the valve core 422 to move to a first position for blocking the first water outlet 412 and to a second position for blocking the second water outlet 413.

[0034] See also Figure 2 In one embodiment, the movement of the valve core 422 is linear movement, and the driving mechanism 421 is one of a telescopic cylinder, an electric cylinder, and an electromagnetic induction component. The driving mechanism 421 drives the valve core 422 to move, so that the valve core 422 can reach a first position for blocking the first water outlet 412 or reach a second position for blocking the second water outlet 413.

[0035] See also Figure 3 In one embodiment, the movement of the valve core 422 is a rotational movement, a channel is provided on the valve core 422, and the valve core 422 can rotate to a position where the water inlet 411 is connected to the first water outlet 412 or rotate to a position where the water inlet 411 is connected to the second water outlet 413. The driving mechanism 421 is one of a motor and a rotary cylinder.

[0036] In one embodiment, the driving mechanism 421 is electrically connected to the water quality detection module 3 , so that the driving mechanism 421 can automatically drive the valve core 422 to move according to the electrical signal of the water quality detection module 3 to achieve switching between the first water pipeline 51 and the second water pipeline 52 .

[0037] In one embodiment, the control mechanism 4 includes a first control valve and a second control valve, wherein the first control valve connects the cleaning water tank 1 and the first water pipeline 51, and controls the on-off of the first water pipeline 51, and the second control valve connects the cleaning water tank 1 and the second water pipeline 52, and controls the on-off of the second water pipeline 52. When water needs to flow through the first water pipeline 51, the first control valve is opened and the second control valve is closed; when water needs to flow through the second water pipeline 52, the second control valve is opened and the first control valve is closed.

[0038] See also Figure 1 In one embodiment, the water circuit structure of the toilet also includes a water pump 8, which is connected between the control mechanism 4 and the cleaning water tank 1. When the water pump 8 is working, it can push the water to flow toward the spray gun 2, thereby increasing the water pressure so that the water can be sprayed out from the spray gun 2 to the position to be cleaned.

[0039] The water circuit structure of the toilet also includes a three-way joint 9 and a connecting pipe 7. The end of the first water pipe 51 away from the control mechanism 4, the end of the second water pipe 52 away from the control mechanism 4 and the connecting pipe 7 are all connected to the three-way joint 9. The spray gun 2 is connected to the end of the connecting pipe 7 away from the three-way joint 9. Through the arrangement of the three-way joint 9 and the connecting pipe 7, the connection between the first water pipe 51, the second water pipe 52 and the spray gun 2 is realized, and the length of the first water pipe 51 and the second water pipe 52 can be shortened, thereby shortening the total length of the first water pipe 51, the second water pipe 52 and the connecting pipe 7, reducing the pipeline volume and reducing costs.

[0040] The filter 6 includes a filter layer, which is used to filter out impurities in the water so that the water flowing to the spray gun meets the cleanliness requirements and prevents the spray gun from being blocked. The filter layer can be composed of a filter mesh layer, a sponge, etc.

[0041] In one embodiment, the filter 6 includes a sterilization layer, which is used to kill bacteria and viruses in the water. The sterilization layer can be formed by an ultraviolet lamp. The sterilization layer is arranged between the filter layer and the control mechanism 4, so that the bacteria and viruses in the water are killed first, and the bacteria and viruses are prevented from continuing to grow and reproduce in the filter layer.

[0042] In a toilet provided with a spray function, it usually also has a sewage flushing function. In one embodiment, the toilet further includes a flushing water tank, which has an independent cavity, that is, the flushing water tank and the cleaning water tank 1 are both independently provided, so that the water storage requirement of the cleaning water tank 1 can be reduced, thereby reducing the volume of the cleaning water tank 1. Moreover, the water used for the sewage flushing function does not need to contact the user's skin, and the water quality requirements are relatively low. The filter 6 is provided between the cleaning water tank 1 and the spray gun 2, and is used to filter the water used for the spray function, reduce the use frequency of the filter 6, and reduce the maintenance cost.
