Embodiment Construction
[0016] see figure 1 and figure 2 Shown is a device for flushing and cleaning toilets in negative pressure mode, which includes a toilet 1 and a sealed water tank 2. The sewage outlet 11 of the toilet 1 communicates with the sewage pipeline 8. There is a water tank body 10 on the sealed water tank 2. The upper cover 6, the conduit 3, the one-way valve 5, the sealing member 7, and the flushing control device 9, the sealing member 7 is located between the water tank main body 10 and the upper cover 6 to play a sealing role; the flushing control The device 9 is located on the sealed water tank 2 and is used to control the flushing mechanism; one end of the conduit 3 is equipped with a one-way valve 5 and the other end passes through the sealed water tank 2 and communicates with the sewage pipeline 8; the sewage pipeline 8 One end communicates with the sewage outlet 11 of the toilet 1 and the other end connects with the main sewage pipeline 12 .

The invention discloses a device for flushing and cleaning toilet bowls with a mode of negative pressure, which comprises a toilet bowl, a sealing water tank, a guide pipe, a sewage draining pipeline and the like. One end of the guide pipe is positioned in the sealing water tank, and the other end thereof is positioned at a pipeline arranged on the sewage draining pipeline, and the sealing water tank is communicated with the sewage draining pipeline through the pipeline. The device has the working mode as follows: when a flushing controlling device is started, a water component in the sealing water tank carries out water drainage, the water flow inside the sealing water tank leaks out downwards so as to lead liquid level to decline, and therefore the negative pressure is generated, the pressure inside the sewage draining pipeline is pumped into the sealing water tank and then instant negative pressure is formed inside the sewage draining pipeline while the pressure of the water flow flushing into the toilet bowl is positive pressure, by this way, the pressure leads the sewage to be pumped into the sewage draining pipeline firstly and finally the toilet bowl is cleaned by clean water; therefore, the device solves the problem of stronger attractive force on the sewage draining pipeline, which is resulted from the problem that the instant pressure and intensity of pressure inside the sewage draining pipeline are higher than those of the flushing water inside the toilet bowl during flushing process of the traditional flushing toilet, and solves the problem of the traditional flushing toilet bowl that the flushing method is carried out after dilution.
Description
technical field [0001] The invention mainly relates to urinals and urinals with water tanks and toilets in sanitary equipment, and is a device for flushing and cleaning the toilets in a negative pressure manner. Background technique [0002] Existing toilets generally adopt the direct flushing or siphon flushing method, or are divided into flushing type, siphon type, jet siphon type, vortex siphon type, volumetric direct discharge type, and flushing type toilet according to the flushing method. The flushing force directly discharges the toilet for cleaning, and in the process of flushing and cleaning, there are various benefits. The mandatory national standard for water-saving toilets has begun to be implemented, but when people are more interested in water-saving, it is inevitable I have doubts about the flushing power of the water-saving toilet; some people have used table tennis balls as an experimental tool when judging the flushing force of the toilet, that is, whether ...
