Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bathroom products, and in particular to a composite water inlet valve and an intelligent toilet. Background Art
[0002] As living standards improve, smart technology is becoming increasingly common in homes. More and more families are opting for smart toilets, such as those with a buttocks-cleaning function. After use, the cleaning mechanism sprays clean water, providing greater comfort than traditional toilet paper wiping, and the water flushing effectively removes dirt.
[0003] To ensure the purity of cleaning water, a separate cleaning water tank is typically installed. This tank is connected to the water inlet pipe via a pipeline. A level switch is installed to detect the water level in the cleaning water tank, and a solenoid valve is installed to control the flow of water into the cleaning water tank. When the water path is normally closed, the solenoid valve must continuously withstand the pressure of the tap water, which places high demands on the reliability of the solenoid valve. The water pump of the cleaning device draws water from the cleaning water tank for cleaning. Due to the limited size of the toilet, the cleaning water tank container is generally small. Water needs to be added during the cleaning process. The diverse cleaning modes cause the water flow rate to vary. Under such operating conditions, the solenoid valve and level switch are frequently opened and closed, affecting the service life of the components. The water inlet of the cleaning water tank uses the same water inlet pipe as the main water tank. When the cleaning device is operating, the main water tank is also filled with water. The water pressure entering the cleaning water tank is significantly reduced, and the output flow of the cleaning water tank may exceed the input flow, resulting in the occurrence of cleaning interruption, which leads to a poor user experience. Therefore, how to improve the water path structure of smart toilets with cleaning functions has become an urgent problem in the field. Summary of the Invention
[0004] In order to overcome the deficiencies in the prior art, the present invention provides a composite water inlet valve and an intelligent toilet that can ensure reliable use of the cleaning function and provide a better user experience.

The elastic force of the spring causes the second connecting rod to swing toward one side, and causes the second closing block to close the second pressure relief port. An electric-controlled presser is provided at one end of the second connecting rod. The electric-controlled presser presses the second connecting rod and overcomes the elastic force of the spring, causing the second connecting rod to swing toward the other side, and causing the second closing block to open the second pressure relief port. At the same time, the second connecting rod pushes the first connecting rod to swing, causing the first closing block to close the first pressure relief port.
[0016] Furthermore, the electrically controlled presser includes a motor and an eccentric wheel. The motor is connected to the eccentric wheel.

DETAILED DESCRIPTION
[0030] The present invention is further described below through specific embodiments.
[0031] Reference Figures 1 to 6 As shown, a composite water inlet valve includes a main body 1, a first valve body 11, a second valve body 12, a first connecting rod 2, a second connecting rod 3, a float assembly 4, an electric control presser 5, a cleaning assembly 6, and a controller.
[0032] The main body 1 is provided with a water inlet channel 13, a first water outlet channel 14, and a second water outlet channel 15;
[0033] The first valve body 11 is provided between the water inlet channel 13 and the first water outlet channel 14 , and the first water outlet channel 14 is connected to the main water tank 7 ;

[0035] The first connecting rod 2 is used to control the opening and closing of the first valve body 11;
[0036] The second connecting rod 3 is used to control the opening and closing of the second valve body 12. When the second connecting rod 3 opens the second valve body 12, it drives the first connecting rod 2 to close the first valve body 11.
[0037] The float assembly 4 is disposed in the main water tank 7, and the float assembly 4 is connected to the first connecting rod 2 and drives the first connecting rod 2 to move;
[0038] The electric-controlled presser 5 is used to drive the second connecting rod 3 to move;
[0039] The cleaning component 6 pipeline is connected to the cleaning water tank 8, and the cleaning component 6 includes a water pump 61, a heating module 62, and a flushing structure 63; the water pump 61 draws out the water in the cleaning water tank 8, and after being heated to a temperature suitable for the human body by the heating module 62, it is sprayed out by the flushing structure 63 to comfortably clean the user's buttocks.
[0040] The controller electrically connects the cleaning component 6 and the electrically controlled presser 5 .
[0041] The cleaning water tank 8 is arranged in the main water tank 7. An overflow pipe 81 is provided in the cleaning water tank 8. The outlet of the overflow pipe 81 is connected to the main water tank 7. A water level sensor 82 is provided in the cleaning water tank 8. The water level sensor 81 is connected to the controller signal.
[0042] The first valve body 11 is provided with a first pressure relief port 111. The first connecting rod 2 is a swing arm structure. The first connecting rod 2 is provided with a first closing block 21 on one side of the rotating shaft and is connected to the float assembly 4 on the other side. The float assembly 4 is driven to rise and fall by the water level of the main water tank 7. The first closing block 21 corresponds to the position of the first pressure relief port 111. When the float assembly 4 floats up, the first connecting rod 2 swings toward one side and the first closing block 21 closes the first pressure relief port 111. When the float assembly 4 descends, the first connecting rod 2 swings toward the other side and the first closing block 21 opens the first pressure relief port. The second valve body 12 is provided with a second pressure relief port 121. The second connecting rod 3 is a swing arm structure. The second connecting rod 3 is provided with a second closing block 31 on one side of the rotating shaft and a spring 32 on the other side. The elastic force of the spring 32 causes the second connecting rod 3 to swing toward one side and causes the second closing block 31 to close the second pressure relief port 121. The electric-controlled presser 5 is provided at one end of the second connecting rod 3. The electric-controlled presser 5 presses the second connecting rod 3 and overcomes the elastic force of the spring 32, causing the second connecting rod 3 to swing toward the other side and causing the second closing block 31 to open the second pressure relief port 121. At the same time, the second connecting rod 3 pushes the first connecting rod 2 to swing, causing the first closing block 21 to close the first pressure relief port 111. The electric-controlled presser 5 includes a motor and an eccentric wheel 52. The motor can be a servo motor 51 or a stepper motor. The motor is connected to the eccentric wheel 52. The eccentric wheel 52 is located above one end of the second connecting rod 3 and rotates to press the second connecting rod 3 downward.
[0043] refer to Figure 7 As shown, an intelligent toilet includes the above-mentioned composite water inlet valve and a flushing assembly 9, including a submersible pump 91, a water diverter valve 92, a ring flushing pipeline 93, and a bottom spray pipeline 94. The submersible pump 91 is arranged in the main water tank 7, and its output port is connected to the water diverter valve 92. The water diverter valve 92 has two output ports and is respectively connected to the ring flushing pipeline 93 and the bottom spray pipeline 94. The submersible pump 91 is connected to the controller signal.
[0044] The following further illustrates this solution with reference to the specific working principle of the smart toilet.
[0045] In the present application, the water inlet priority of the cleaning water tank 8 is higher than that of the main water tank 7. For example, when both the main water tank 7 and the cleaning water tank 8 need to be filled with water, the water level sensor 82 in the cleaning water tank 8 detects a water shortage signal and transmits it to the controller, which controls the electric presser 5 to work, and the servo motor 51 drives the eccentric wheel 52 to rotate a certain angle, so that the eccentric wheel 52 presses down one end of the second connecting rod 3. At this time, the second connecting rod 3 swings to separate the second closing block 31 from the second pressure relief port 121, the second valve body 12 opens, the water inlet channel 13 is connected to the second water outlet channel 15, and clean water enters the cleaning water tank 8. When the second connecting rod 3 swings to this state, it will simultaneously push the first connecting rod 2 to swing, causing the first closing block 21 to close the first pressure relief port 121. At this time, all the water in the water inlet channel 13 will enter the cleaning water tank 8 through the second water outlet channel 15. Until the cleaning water tank 8 is full, the water level sensor 82 detects the full water signal and transmits it to the controller. The controller controls the electric presser 5 to work, and the servo motor 51 drives the eccentric wheel 52 to rotate a certain angle to disengage from the second connecting rod 3, so that the second connecting rod 3 is reset under the action of the spring 32, and the second closing block 32 closes the second pressure relief port 121 and then closes the second valve body 12; when the first connecting rod 2 loses the push of the second connecting rod 3, it will swing under the drive of the float assembly 4, and the first closing block 21 opens the first pressure relief port 111 to open the first valve body 11, and the water inlet channel 13 is connected to the first water outlet channel 15, filling the main water tank 7 with water until the float assembly 4 floats to drive the first closing block 21 of the first connecting rod 2 to close the first pressure relief port 111. At this time, the main water tank 7 is full.
[0046] The purpose of giving the cleaning water tank 8 a higher water inlet priority than the main water tank 7 is that when the user goes to the toilet, the main water tank 7 flushes and the float assembly 4 descends to fill the water. At this time, if the cleaning function is used, in order to ensure that the cleaning function has sufficient water flow, the composite water inlet valve structure of the present application can close the first water outlet channel 14, so that all the water in the water inlet channel 13 is supplied to the cleaning water tank 8 through the second water inlet channel 15. When the cleaning water tank 8 is filled, the excess water in it will also enter the main water tank 7 through the overflow pipe 81. Therefore, during the use of the cleaning function, there is no need to frequently open and close the second valve body 12 and there can be sufficient water inlet flow, which improves the service life of the equipment. Since the outlet of the overflow pipe 81 enters the main water tank 7, the drop is small and it is directly injected into the water body, so the overflow sound is small and the user experience is good.
[0047] Since the cleaning water tank 8 is arranged in the main water tank 7, a larger cleaning water tank 7 can be set, which can accommodate sufficient cleaning water. The water level sensor 82 is set to open the water intake only when a lower water level is detected, which can also meet the flushing water demand. Therefore, the number of times the second valve body 12 is opened can also be reduced.
[0048] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
