DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The present utility model provides a technical solution: Referring to Figure 1 - Figure 5 , an intelligent water-saving toilet disclosed by the present utility model includes a water tank 1 installed in the intelligent toilet sink. A drainage mechanism 2 is provided on the water tank 1, a water injection mechanism 4 is provided at the top of the water tank 1, and a limiting mechanism 3 is provided on the right side of the water tank 1;

[0026] The drainage mechanism 2 includes a piston plate 21 which is slidably installed in the water tank 1. High-pressure air is filled between the bottom side of the piston plate 21 and the inner wall of the water tank 1. The limiting mechanism 3 includes a plurality of limiting rods 32. A plurality of round holes 31 are opened on the inner wall of the right side of the water tank 1, and the limiting rods 32 are slidably installed in the corresponding round holes 31. The distance between adjacent two round holes 31 is equal. A sealing ring 33 is installed at the position of the water tank 1 corresponding to the round holes 31, and the inner ring wall of the sealing ring 33 is in contact with the outer peripheral wall of the corresponding limiting rod 32. A driving member 34 is provided on the right side of the water tank 1.

[0027] In this embodiment, when the improved intelligent water-saving toilet flushes, the driving member 34 will push the hemispherical end of the corresponding limiting rod 32 into the water tank 1 as needed. Due to the pushing of the gas in the water tank 1 on the piston plate 21, the piston plate 21 will inject the water in the water storage tank 1 into the feces tank through the water injection mechanism 4 to complete the flushing operation of the toilet. When the piston plate 21 moves to the position of the limiting rod 32, due to the mutual resistance between the limiting rod 32 and the piston plate 21, the piston plate 21 stops moving upward, and the corresponding amount of water in the water tank 1 is discharged from the water tank 1. The drainage volume is relatively accurate, reducing water waste. There are few electrical equipment in the device and it does not need to run continuously, reducing the power consumption of the intelligent toilet.

[0028] In a further preferred embodiment of the present utility model, as Figure 2 shown, a one-way valve 22 is provided at the bottom end of the front side of the water tank 1, and the exhaust end of the one-way valve 22 fixedly penetrates the tank wall of the water tank 1, and the one-way valve 22 is located below the piston plate 21;

[0029] In this embodiment, the setting of the one-way valve 22 enables the amount of gas in the water tank 1 to be replenished, avoiding the device being unable to work properly after some gas in the water tank 1 overflows.

[0030] In a further preferred embodiment of the present utility model, as Figure 2 shown, an electronically controlled water inlet valve 23 is provided at the top end of the front side of the water tank 1, and the drainage end of the electronically controlled water inlet valve 23 fixedly penetrates the tank wall of the water tank 1;

[0031] In this embodiment, after the water in the water tank 1 is completely discharged, the electronically controlled water inlet valve 23 opens. At this time, due to the pressure difference at both ends of the electronically controlled water inlet valve 23, the external water flows into the water tank 1 through the electronically controlled water inlet valve 23. And as the external water is injected into the water tank 1, the piston plate 21 descends accordingly to compress the air in the water tank 1, thereby making the pressure difference at both ends of the electronically controlled water inlet valve 23 equal, and the external water will not continue to flow into the water tank 1. A specific amount of water is always stored in the water tank 1 without requiring other operations from the operator, and the degree of automation of the device is high.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the opening wall at one end of the round hole 31 is arranged in an arc shape curved towards the axis direction. One end of the limiting rod 32 is arranged in a hemispherical shape. A soft ring 35 is slidably sleeved on the hemispherical end of the limiting rod 32, and the outer peripheral wall of the soft ring 35 is in contact with the inner wall of the corresponding round hole 31. One end of the soft ring 35 away from the corresponding limiting rod 32 is coplanar with the inner wall of the water tank 1;

[0033] In this embodiment, the arc-shaped arrangement of the round hole 31 can restrict and position the limiting rod 32, and the limiting rod 32 will not slide out of the round hole 31. When the hemispherical end of the above-mentioned limiting rod 32 extends out of the round hole 31, the soft ring synchronously expands and contracts deforms to expand the inner hole of the soft ring. The setting of the soft ring will not affect the hemispherical end of the limiting rod 32 from extending out of the round hole 31. After the limiting rod 32 retracts into the round hole 31, the soft ring expands and contracts deforms and automatically retracts into the round hole 31 to closely fit the hemispherical end of the limiting rod 32, automatically blocking the opening of the round hole 31 and will not affect the piston plate 21's pushing of the water in the water tank 1.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 - Figure 5 shown, the driving member 34 includes a housing 341. The housing 341 is fixedly installed at the position corresponding to the round hole 31 on the right side of the water tank 1 through bolts. A plurality of exciting coils 342 are arranged in the housing 341, and the limiting rod 32 is a magnetic rod. One end of the exciting coil 342 is fixedly connected to the inner wall of the housing 341;

[0035] In this embodiment, when the limiting rod 32 is pushed out of the round hole 31 again, the exciting coil 342 at the corresponding position is started. Due to the repulsive force between the exciting coil 342 and the limiting rod 32, the spherical end of the limiting rod 32 extends out of the round hole 31 until the spherical end of the limiting rod 32 abuts against the inner arc wall of the round hole 31 or the soft ring. The upward movement distance of the piston plate 21 is controlled by the limiting rods 32 at different positions, thereby controlling the discharge amount of the water in the water tank 1, and the discharge amount is relatively accurate.

[0036] In a further preferred embodiment of the present utility model, as Figure 4 andFigure 5 As shown, at the other end of the excitation coil 342, a plugging block 343 with a T-shaped cross-section is fixedly installed. One end of the plugging block 343 away from the inner wall of the outer shell 341 is inserted into the opening at the other end of the corresponding round hole 31 and is in interference fit with the inner wall of the opening at the other end of the corresponding round hole 31, the outer wall of the water tank 1, and the other end of the limit rod 32;

[0037] In this embodiment, when replacing and repairing the excitation coil 342, the operator screws out the bolts inside the outer shell 341, and then the excitation coil 342 can be directly removed from the water tank 1 by moving the outer shell 341 for inspection and replacement of the excitation coil 342. After the inspection or replacement of the excitation coil 342 is completed, the operator fixes the outer shell 341 on the water tank 1 again through the bolts and makes the plugging block 343 re-inserted into the round hole 31 to plug the opening of the round hole 31;

[0038] When disassembling the outer shell 341 as described above, the plugging block 343 can be directly taken out from the round hole 31. At this time, the limit rod 32 can be taken out from the round hole 31 through the opening of the round hole 31 for replacement, which facilitates the maintenance of the device.

[0039] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, the water injection mechanism 4 includes a water pipe 42. An electric control drain valve 41 is provided at the central position on the top side of the water tank 1, and the water inlet end of the electric control drain valve 41 fixedly penetrates the tank wall of the water tank 1. The water inlet end of the water pipe 42 is connected and installed with the drain end of the electric control drain valve 41;

[0040] In this embodiment, when draining the water in the water tank 1 as described above, the electric control inlet valve 23 is closed, and the electric control drain valve 41 is opened for a specific duration. Due to the pushing of the gas in the water tank 1 on the piston plate 21, the piston plate 21 automatically moves upward, and the water in the water tank 1 is discharged into the water pipe 42 from the electric control drain valve 41 until the limiting plate abuts against the hemispherical end of the limit rod 32. The water discharged from the electric control drain valve 41 is introduced into the manure tank through the water pipe 42. After the electric control drain valve 41 is closed, the electric control inlet valve 23 is opened to complete the above-mentioned water injection operation of the water tank 1. The device has a high degree of automation and does not require more electrical equipment.

[0041] Working principle: When the improved intelligent water-saving toilet is in use, first, the excitation coil at the corresponding position starts. Due to the repulsive force between the excitation coil 342 and the limit rod 32, the spherical end of the limit rod 32 extends out of the round hole 31 until the spherical end of the limit rod 32 abuts against the inner arc wall of the round hole 31. At the same time, the electric control water inlet valve 23 closes, and the electric control drain valve 41 opens for a specific duration. Due to the push of the gas in the water tank 1 on the piston plate 21, the piston plate 21 automatically moves upward, and the water in the water tank 1 is discharged into the water pipe 42 through the electric control drain valve 41 until the limit plate abuts against the hemispherical end of the limit rod 32. The water discharged from the electric control drain valve 41 is introduced into the feces tank through the water pipe 42;

[0042] It should be noted that due to the limited water flow rate at the electric control drain valve 41, the upward movement rate of the piston plate 21 will not be too fast, thus greatly reducing the inertial force when the piston plate 21 moves upward, and further avoiding the impact force when the piston plate 21 contacts the hemispherical end of the limit rod 32;

[0043] After the above-mentioned electric control drain valve 41 closes, the electric control water inlet valve 23 opens. At this time, due to the pressure difference at both ends of the electric control water inlet valve 23, the external water flow passes through the electric control water inlet valve 23 and flows into the water tank 1. And as the external water is injected into the water tank 1, the piston plate 21 descends accordingly to compress the air in the water tank 1, thereby making the pressure difference at both ends of the electric control water inlet valve 23 equal, and the external water will not continue to flow into the water tank 1. A specific amount of water is always stored in the water tank 1;

[0044] It should be noted that after the above-mentioned electric control drain valve 41 closes and the electric control water inlet valve 23 opens, the excitation coil stops being powered.

[0045] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
