The specific working principle of the toilet 10 and the pressure storage pack 100 is as follows:
referring to fig. 4, the pressure storage pack 100 is in an initial state, water storage is not started, and the piston assembly 130 is in an initial position. The water inlet valve 300 is opened, water enters the second chamber 10b from the water inlet 121, and the piston assembly 130 is pushed to move away from the second housing 120 and toward the first housing 110 by the pressure of the water.
Referring to fig. 5, when the piston assembly 130 moves to the first predetermined position, the pull wire 153 straightens, and the valve core 151 does not start rotating. Continuing to feed water, the piston assembly 130 continues to move and the pull wire 153 begins to pull the valve core 151 to rotate relative to the second housing 120 about the rotation shaft 152.
Referring to fig. 6, when the piston assembly 130 moves to the second predetermined position, the water guide pipe 155 is aligned with the water outlet 122, and the water outlet 122 starts to discharge water. At this time, the piston assembly 130 moves to the top of the first housing 110, and the flushing can be performed through tap water, so as to ensure the flushing flow. Then, the water inlet 121 is closed, and the piston assembly 130 moves toward the second housing 120 away from the first housing 110 by the restoring force of the spring 140, forcing the water in the second chamber 10b to flow out of the water outlet 122 through the water guide pipe 155.
Referring to fig. 7, when the piston assembly 130 moves back under the restoring force of the spring 140, one end of the piston rod 132 abuts against the restoring rod 154. At this time, the water guide pipe 155 of the valve core 151 is still aligned with the water outlet 122, and the water outlet 122 can still discharge water.
Referring to fig. 8, the piston rod 132 continues to move under the restoring force of the spring 140, the piston rod 132 pushes the restoring rod 154, so that the valve core 151 is forced to reversely rotate around the rotation axis relative to the second housing 120 until the water guide pipe 155 is completely staggered from the water outlet 122, and the water outlet 122 is sealed. At this time, the piston assembly 130 returns to the initial position.
Because the toilet 10 and the pressure storage pack 100 thereof can be opened through the water inlet 121 and the water outlet 122 at the same time, the inner container of the toilet 10 is firstly washed or scrubbed, then the water inlet 121 is closed, and the water in the second cavity 10b is forced to flow out from the water outlet 122 under the action of the restoring force of the spring 140, so that the washing pressure and the washing flow can be effectively ensured.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention.
