Footpath is the 1/5 ~ 1/3 of main through-hole diameter, and the leaking hole set on the top cover is corresponding with the top of main through hole and sub-through hole.
Preferably, main through hole top is provided with support, and the support is integrally formed with positioning pipe, under cantilever tip and top cover
It is close on surface.
Preferably, water inlet one end diameter is more than bottom delivery port one end 5 ~ 10mm of diameter at the top of sub-through hole.
Preferably, it is provided with screw thread on the main through-hole wall immediately below sub-through hole delivery port.
Compared with prior art, the beneficial effects of the utility model are：
（1）The utility model is simple in construction, is improved on the architecture basics that traditional vacuum tail is taken over, utilizes physics
Principle carries out reasonable direction to current so as to produce bigger impulsive force, and then reduces the bending that solvent deposition is taken in vacuum tail
Place, is greatly reduced the cleaning difficulty after vacuum tail adapter use.
（2）Main through hole top is provided with support in the utility model, and the machinery that support effectively enhances integral device is strong
Degree, the power extruded to main through hole center can be produced when sub-through hole long-time draining, and the main function of support exactly squeezes this
Pressure is offset the service life with extension device, while the support that cradle top can be also aided in top cover.
（3）In utility model neutron via top water inlet one end, diameter is more than bottom delivery port one end 5 ~ 10mm of diameter,
Increase impulse force of the current after being drained by sub-through hole, further optimize the using effect of the equipment.
（4）Screw thread is provided with main through-hole wall immediately below sub-through hole delivery port, is realizing that increase is inhaled by sub-through hole
While power, aided in screw thread, the secondary suction size strengthened equipment and can be generated.
