Example 3

The embodiment discloses a bubble-sealed water-saving intelligent public toilet, which is further limited on the basis of the embodiment, and is specifically as follows.

Referring to fig. 7-9 of the specification, the center of gravity of the sealing plate 102 is offset, and the sealing plate 102 automatically rotates from an open state to a closed state by means of gravity force; when the sealing plate 102 rotates reciprocally, the center of gravity of the sealing plate does not reach the plumb line passing through the hinge point. After the dirt in the urinal 15 is discharged, the sealing plate 102 is of a gravity-biased integral structure, so that the sealing plate 102 can automatically rotate from an open state to a closed state under the action of gravity, the sealing plate 102 completely relies on the gravity to realize the automatic reset effect, and the water outlet 105 of the shell 1 is sealed to realize the deodorization. In addition, as the center of gravity of the sealing plate 102 does not reach the plumb line passing through the hinge point when the sealing plate reciprocally rotates between the open state and the closed state, the situation that the gravity cannot be reset if the center of gravity passes through the plumb line of the hinge point in the rotation process is avoided.

Because of the special structural design, the stress analysis of the sealing plate 102 proves that the sealing plate 102 can generate a moment on the sealing plate 102 completely by means of gravity of the sealing plate 102 under the condition of no external force, so that the sealing plate 102 rotates around the clamping shaft 104 towards the lower opening 108 of the water outlet 105, at least can just reset, and the water outlet 105 of the shell 101 is just closed.

Further, the sealing plate 2 is provided with a containing box 24, and the containing box 24 is used for placing a counterweight. In this embodiment, when the balancing weight is disposed in the accommodating box 24, the center of gravity of the structure formed by combining the balancing weight and the sealing plate 102 does not reach the plumb line of the hinge point during the reciprocating rotation of the sealing plate 102. In this embodiment, the sealing plate 102 is configured with the balancing weight, so that the sealing plate 102 is easier to reset, and because the balancing weight on the sealing plate 102 is placed in the accommodating box 24, the balancing weight is not fixed on the sealing plate 102, and the balancing weight can be detached, so that the balancing weight with proper weight can be flexibly selected according to actual needs. For example, when the flushing pressure of the toilet bowl 4 is small, a lightweight weight may be selected to be placed in the housing case 24 of the sealing plate 102 in order to smoothly open the sealing plate 102 of the deodorizing valve.

Further, in the closed state of the sealing plate 102, the included angle α between the sealing plate 102 and the lower opening 108 of the drain opening 105 is 45 degrees. This angular setting makes it easier to reset the sealing plate 102 by its own weight, and at the same time to open it.
