TECHNICAL FIELD

[0001] The present application relates to a squatting toilet for mobile toilet, in particular to a squatting toilet with negative pressure suction and crushing lifting function. BACKGROUND

[0002] In the emergency security accommodation and large-scale temporary meeting place, in order to solve the personnel toilet problem, while meeting the environmental protection requirements on site, usually adopt container type no support mobile toilet, mobile toilet is equipped with flushing water, power supply and excrement treatment device, uses squatting toilet, and the ground is not excavated septic tank and sewage pipe.

[0003] Usually, in order to ensure that the excrement is washed clean after defecation, the ordinary toilet adopts siphon type or vacuum pump suction type structure after the toilet flushing on the basis of the toilet excrement outlet. The height of the standard container is fixed, in order to ensure that the personnel can stand freely in the toilet, the overall height of the squatting toilet is limited, and the siphon type structure commonly used in ordinary toilets cannot be used. In addition, the mobile toilet is powered by solar energy and battery pack, and the power supply power is limited. The vacuum pump suction type needs to increase the vacuum pump, the interface valve and the gas storage tank and other equipment, so that the system is complex, the power supply power demand is increased, and the use reliability of the whole toilet is reduced.

[0014] The present application has the following beneficial effects:

[0015] 1. The present application integrates the crushing lifting pump into the bottom of the squatting toilet, so as to meet the height space limitation in the design of mobile toilets;

[0016] 2. The water inlet pipe is divided into two routes, including the crushing pool water inlet pipeline for pre-watering to the crushing pool and the squatting toilet water inlet pipeline; when flushing the toilet, one way of water enters the toilet pool through the small holes around the toilet; the other way of water is introduced into the crushing pool through the crushing pool water inlet pipe 8, and the pressure water reaches the crushing pool in advance due to the short pipeline of the crushing pool water inlet pipe 8, so that the crushing lifting pump 4 starts to work when the liquid level of the crushing pool exceeds the upper limit; since the crushing pool is a sealed structure, when the crushing lifting pump 4 discharges sewage into the sewage lifting pipe 7, a negative pressure is formed in the crushing pool, and the sewage in the toilet is sucked into the crushing pool more quickly and cleanly under the double action of flushing pressure water and negative pressure suction in the crushing pool.

[0017] 3. The present application adopts one-way exhaust design, which forms a negative pressure effect in the crushing pool at the bottom of the entire squatting toilet when the crushing lifting pump is working, and the negative pressure suction does not use a vacuum pump, so that the sewage in the toilet is sucked into the crushing pool more quickly and cleanly under the action of negative pressure suction in the crushing pool.
