Toilets in daily life are closely related to human life, and toilets can be divided into two main types, namely a toilet and a squatting pan. The toilet is divided into a connected type and a separated type according to the type, and is divided into a rear discharge type and a lower discharge type according to the sewage discharge direction, and is divided into a flushing type and a siphon type according to the water-pressing mode. The squatting pan is characterized by human body bending squatting type when in use, and can be divided into a water return bend and a water return bend free according to the structure, wherein the squatting pan with the water return bend utilizes a transverse S-shaped bent pipe to form a water seal, so that the odor of a sewer is prevented from flowing backwards; the most common toilet is the squatting pan, which has simple structure and convenient and quick use, but has potential safety hazards of insanitation, incomplete flushing, etc.
For squatting pan, the most important function is flushing, and the common flushing modes are classified into a push type and a pedal type; both flushing modes utilize the impulsive force of water flow to discharge dirt, so that a great amount of water is wasted when flushing is carried out under normal pressure, and the problem of incomplete flushing also exists. At present, a vacuum excrement collector is more and more common, and when flushing, dirt is conveyed into a dirt box through pressure difference generated between the excrement collector and the dirt box and then discharged into a sewer; the toilet bowl is clean to wash and saves water, but has a complex structure, high cost, easy failure and inconvenient maintenance. At present, the squatting pan of the public toilet is in a flushing mode, and vacuum excrement collection is not applied yet, and the main reasons are high cost, more faults and difficult maintenance. However, the public toilet is generally applied to an area with huge traffic, the number of people using the public toilet is huge, the simple flushing by water is unreasonable, the public toilet cannot be flushed cleanly, in addition, the individual quality is not high, the public toilet is unwilling to flush after the toilet is used, the public toilet is dirtied and malodorous with the continuous accumulation of the number of people, the hidden danger of sanitation is great, and the spread of bacteria and diseases is accelerated.
The semi-automatic toilet flushing device provided by the application well solves the problems, skillfully utilizes the thrust of the toilet door, when the toilet door is pushed open, the toilet door pulls the flexible rope to generate moment to drive a set of pulley block, a set of labor-saving mechanism is formed to drive a manual vacuum pump, the pulley block can save 5/6 of force, and the door can be easily pushed open; the manual vacuum pump generates vacuum in the vacuum transition box, forms a pressure difference with the toilet bowl, and quickly conveys dirt into the dirt box in a mode of combining the pressure difference with water flow impulse; the toilet flushing device has the advantages of simple structure, simplicity in operation, high reflection speed, high toilet flushing efficiency, lower cost, convenience in maintenance, water saving, thorough toilet flushing, avoidance of people unwilling to flush the toilet, and the like.
