Description

Valveless vacuum floor drain lifter Technical Field The invention relates to a vacuum sanitary appliance, in particular to a valveless vacuum floor drain lifter for collecting ground sewage. Background The vacuum drainage technology has been widely used for collecting and draining indoor and outdoor sewage with unique advantages, the indoor vacuum drainage application occasions such as toilets, shops and kitchens have huge demands, the existing vacuum lifter generally comprises a sewage temporary storage box body, a liquid level detection mechanism and a vacuum interface valve, when sewage flows into the sewage temporary storage box body through gravity, the liquid level detection mechanism detects that the liquid level of the sewage in the box body reaches a high liquid level, the vacuum interface valve is opened, the sewage is pumped away through the vacuum interface valve until the liquid level of the sewage in the box body returns to a low liquid level, the vacuum lifter is complex in structure and high in failure rate, and a space occupied by the vacuum lifter is required to build a wall for setting the liquid level detection mechanism and the vacuum interface valve. Disclosure of Invention The invention aims to overcome the defects of the technology, and provides a valveless vacuum floor drain lifter which is not only free of a liquid level detection mechanism and a vacuum interface valve and free of a separate occupied space for arranging a wall, but also simple and reliable in structure and low in failure rate, and can be randomly arranged at any position of a water-using room such as a kitchen, a bathroom and the like a common floor drain to collect scattered surface sewage. The valveless vacuum floor drain lifter is characterized in that the floor drain box body is hollow, the top of the floor drain box body is open, a water outlet is transversely arranged at the bottom of the floor drain box body, a rubber ring is further arranged at the inner side of the water outlet, and the outer side of the water outlet is connected with a vacuum drainage pipeline. The center height of the water outlet is larger than the radius of the floating ball. The end face of the rubber ring and the floor drain the included angle of the bottom surface of the box body is 75-90 degrees. The floating ball is arranged in the floor drain box body and is in a free state. The floating ball is made of hollow stainless steel or plastic, and the buoyancy is far greater than the gravity. The surface of the floor drain cover is provided with a plurality of small holes, and the floor drain cover is buckled with the top end of the floor drain box body. The valveless vacuum floor drain lifter is embedded on the floor of water rooms such as kitchens, toilets and the like, and the upper end surface of the valveless vacuum floor drain lifter is slightly lower than the ground. The valveless vacuum floor drain lifter is characterized in that ground sewage flows into the floor drain box body from the floor drain cover, when the sewage liquid level in the floor drain box body is smaller than the starting liquid level, the floating ball clings to the rubber ring under the action of negative pressure to seal the vacuum drainage pipeline, and when the sewage liquid level is larger than the starting liquid level, the floating ball breaks away from the rubber ring under the action of buoyancy, and sewage in the floor drain box body is pumped out by the vacuum drainage pipeline. The vacuum drainage pipeline has the beneficial effects that the vacuum drainage pipeline is not required to be controlled by the vacuum interface valve, and the effects of opening at a high liquid level and closing at a low liquid level can be achieved by means of the interaction between the negative pressure in the vacuum drainage pipeline and the floating ball.
