The water tank 8 is located above and behind the bracket 2 and is fixedly connected to the two movable slide rails 5. A water inlet 6 is provided on one side of the upper end of the water tank 8 and a safety valve 7 is provided on the other side. The two flushing valves 12 are arranged in the basin ears 23 on both sides. The upper end of the flexible sewer pipe 1 is connected to the sewage outlet 24 of the basin body 10, and the lower end is connected to the upper end of the dynamic sewer pipe 13. The lower end of the dynamic sewer pipe 13 is inserted into the static sewer pipe 14 for sliding connection and a sealing ring is provided at the connection. The bottom of the water tank 8 is connected to the inside of the flushing valves 12 on both sides through the flushing pipe 3. When the basin body 10 moves from the 90° position to the 45° position, the flushing valve 12 is fully opened to achieve high-pressure water 45° When the basin body 10 moves from the 45° position to the 0° position, the flush valve 12 is completely closed. The two flow-limiting valves 15 in the flush pipe are circular sheet-shaped valve disc structures, which are respectively arranged in the flush pipe 3 below the water tank 8, and the two flow-limiting valves 15 in the flush pipe are connected by a connecting rod. The seat cushion 9 is located above the basin body 10, and the rear end of the seat cushion 9 is fixedly connected to the middle of the connecting rod between the two flow-limiting valves 15 in the flush pipe; the flow-limiting valve 15 in the flush pipe rotates synchronously with the seat cushion 9. When the seat cushion 9 is retracted and not in use at 90°, the valve disc of the flow-limiting valve 15 in the flush pipe forms a 45° angle with the inner wall of the flush pipe 3, and the water discharge flow is small. When the seat cushion 9 moves to 45° with the basin body, the valve disc of the flow-limiting valve 15 in the flush pipe is parallel to the inner wall of the flush pipe 3, and the water discharge flow is maximized, distinguishing between urination and defecation flushing, and further realizing water saving.
[0040] The flush valve 12 includes a flush valve moving valve disc 17, a flush valve static valve disc 18, a flush valve body, and a valve cover. The flush valve moving valve disc 17 is provided with two toggle holes. The flush valve moving valve disc 17 is placed in the basin ear 23, and two toggle claws 25 are inserted into the two toggle holes. The flush valve static valve disc 18 is coaxially arranged on the outside of the flush valve moving valve disc 17. A number of arc holes are provided on the flush valve moving valve disc 17 and the flush valve static valve disc 18. The flush valve body is buckled at the end of the basin ear 23, and the flush valve cover covers the end of the flush valve body. The flush valve moving valve disc 17 rotates synchronously with the basin body 10 through the drive of the toggle claws 25. The flush valve static valve disc 18 is fixed to the flush valve 12 housing. When the basin body 10 is at a 90° position, the arc holes on the flush valve moving valve disc 17 and the flush valve static valve disc 18 are completely staggered, and the flush valve 12 Closed, when the basin body 10 moves from 90° to 45°, the overlapping part of the arc-shaped holes on the flush valve movable valve plate 17 and the flush valve static valve plate 18 is small but gradually increases, and the flush valve 12 gradually opens. When the basin body 10 is at 45°, the arc-shaped holes on the flush valve movable valve plate 17 and the flush valve static valve plate 18 completely overlap, and the flush valve 12 is fully opened. When the basin body 10 moves from 45° to 0°, the overlapping part of the arc-shaped holes on the flush valve movable valve plate 17 and the flush valve static valve plate 18 is large but gradually decreases; the water tank opening design is a sliding valve to open the toilet, and the flush valve can be opened and closed when the toilet basin body is folded between 0°~45°~90°, and the flushing volume is controlled by the speed of the folding action. The flushing can be distinguished by urination or defecation by folding or lowering the seat cushion 9. The water tank is designed with a safety valve to effectively control the water tank pressure within a safe range.
[0041] The working process of this utility model:
[0042] The basin body 10 of the utility model can be folded and stowed at 0 to 90 degrees, which is much shorter than the existing toilet. At the same time, the wall-mounted design can effectively reduce the occupied space, better save the limited space of the bathroom and daily hygiene care, and protect this folding wall-mounted, liftable, and pressure-storage flushing toilet method.
[0043] When the toilet is not in use, the basin 10 is folded and retracted to a 90° position. At this time, the seat cushion 9 is also at a 90° position. The flow limiting valve 15 in the flush pipe is perpendicular to the inner wall of the flush pipe 3. At this time, when the basin is lowered to use the toilet, the vertical flushing volume is minimal. The arc-shaped holes on the flush valve movable valve plate 17 and the flush valve static valve plate 18 are completely offset, the flush valve is closed, and the flushing system is disconnected.
[0044] When the motor quickly drives the driving gear 19 to drive the driven gear 11 or the basin body 10 is quickly driven manually to rotate from a 90° to a 45° position, the basin ear 23 rotates and drives the flush valve movable valve plate 17 to rotate through the pusher claw 25. The overlapping portion of the arc-shaped holes on the flush valve movable valve plate 17 and the flush valve static valve plate 18 is small but gradually increases. At this time, the function of the flushing system is to wet the basin body 10, so that the basin body 10 is better flushed when draining sewage, and the water consumption is small.
[0045] When the basin body 10 is rotated from 0° to 45° simultaneously by the motor or manually at a slow speed, the arc-shaped holes on the flush valve moving valve disc 17 and the flush valve static valve disc 18 are completely overlapped, the flush valve 12 is fully opened, the valve disc of the flow limiting valve 15 in the flush pipe is parallel to the inner wall of the flush pipe 3, and the water discharge flow is maximum. At this time, the flushing volume of the flushing system is maximum, the basin body 10, the sewage outlet 24 and the center line of the flexible sewer pipe 1 are in a straight line, and the resistance is small. The pressurized water flows from the water tank 8 along the flush pipe 3 into the flush valve 12, passes through the arc-shaped holes on the flush valve moving valve disc 17 and the flush valve static valve disc 18, and flushes and discharges the dirt in the basin body 10 through the flush hole. The discharged dirt enters the dynamic sewer pipe 13 from the sewage outlet 24, and then is discharged along the static sewer pipe 14. A sealing ring is provided at the connection between the dynamic sewer pipe 13 and the static sewer pipe 14, which can effectively prevent leakage and sewer odor problems during the sewage discharge process;
[0046] During the rotation of the basin body 10 and the seat cushion 9 from 45° to 0°, the overlapping portion of the arc-shaped holes on the movable valve plate 17 and the static valve plate 18 of the flush valve is large but gradually decreases to complete misalignment, the flush valve is closed, and the flushing system is disconnected.
[0047] Flushing when the basin body 10 is folded at 45° is more conducive to flushing away waste, and the flushing volume can be manually controlled according to the flushing situation of waste. The speed of folding the basin body 10 is adjusted to achieve the purpose of saving water. The water-saving method of flushing the toilet at 45° using the toilet bowl body is protected, and the flushing form with a pressurized water tank is protected. The flow limiting valve 15 in the flush pipe can adjust the angle through the up and down movement of the seat cushion 9 to control the water volume. It can be used to distinguish between flushing for urination and defecation, thereby achieving further water saving.
[0048] When the toilet is in use, the basin body 10 and the seat cushion 9 are rotated to the 0° position, which can control the lifting and lowering of the telescopic rod of the lifting cylinder 16. Since the upper end of the telescopic rod is fixed, when the telescopic rod is extended, the barrel of the lifting cylinder 16 drives the bracket 2 to slide downward along the static slide rail 4 and the movable slide rail 5 through the cylinder body connecting plate 20, thereby lowering the height of the basin body 10, and at the same time, the dynamic sewer pipe 13 extends downward into the static sewer pipe 14. Conversely, when the telescopic rod is shortened, the height of the basin body 10 rises, and the dynamic sewer pipe 13 extends upward. Through the above operation, the function of adjusting the height of the toilet according to the user's height can be realized, and the air pressure inside the cylinder can be adjusted by the cylinder pressure regulating handle 22 to adjust the up and down movement of the cylinder.
