The proportion of the gas and the water can be adjusted by adjusting the flow proportion of the 3 water supply system and the 4 air supply system, thereby adjusting the foaming amount.
The invention has the following beneficial effects:
1. the drag reduction wall surface structure improves the sewage discharge flushing principle, and if the conventional excrement collector adopts a high-pressure water column to perform pre-wetting and post-defecation flushing, the mode has no lubrication in the excrement discharging process, adhesion occurs, more water is needed to flush, and the water consumption of a typical vacuum excrement collecting system is 0.4-0.6L per time. The invention realizes micro water outlet and air bubbles through the micro flow channel and the surface micropores, the air bubbles are discharged from the micropores, the surface tension is larger, the micro water can cover a larger surface area, and meanwhile, the vibration and the impact when the micro bubbles are broken are beneficial to removing dirt. The surface can be continuously wetted in a trace water foaming mode in the whole using process, and the adhesion is radically reduced by isolating and supporting the dirt through the micro bubbles covered on the wall surface, so that the flushing water is reduced. Meanwhile, the micropores enable the surface of the closestool to form a layer of bubble water film in a surface sweating mode, the continuous bubble water film avoids vacuum leakage during vacuum pollution discharge, the resistance of vacuum suction is reduced through lubrication, and the pollution discharge is more efficient and thorough.
2. The high-pressure water washing in the prior art has the problem of water splashing, and the sanitation and the use experience are not good. The surface of polytetrafluoroethylene and the microporous structure through not being stained with make this excrement collector need not high-pressure water column and wash by water, use atomizing nozzle or low pressure nozzle can, this moment mouth function be drenched and wash, rather than lean on water column pressure to carry out the physical impact to the filth of adhesion on the inner wall, consequently can reduce the water, still avoid the sputtering problem simultaneously. Meanwhile, the surface micro bubbles have larger surface tension, so that the dirt is not easy to splash when falling.
3.
