Abstract
The utility model discloses a suck-back device for a negative-pressure suction system. The suck-back device for the negative-pressure suction system comprises: a negative-pressure bottle is communicated with the negative-pressure suction system; a negative-pressure ventilating pipe is communicated with the negative-pressure bottle; the negative-pressure bottle is communicated with the negative-pressure suction system through the negative-pressure ventilating pipe; and a spill-proof plug is arranged in the negative-pressure bottle and on the end part of the negative-pressure ventilating pipe. The spill-proof plug of a floating plug component lifts under the action of buoyant force and blocks the negative-pressure ventilating pipe so as to prevent liquid in the negative-pressure bottle from overflowing into a negative-pressure branch pipe and solve the blockage problem of the negative-pressure system. The utility model discloses a negative-pressure system terminal component. The negative-pressure system terminal component comprises a negative-pressure branch pipe of the negative-pressure system, a negative-pressure bottle, a spill-proof plug and a mounting pipe, wherein the negative-pressure bottle is communicated with the end part of the negative-pressure branch pipe; the spill-proof plug is arranged in the negative-pressure bottle and on the end part of the negative-pressure branch pipe; and the mounting pipe is communicated with the negative-pressure bottle. The negative-pressure system terminal component adopts the negative-pressure bottle device with the spill-proof plug so as to effectively avoid pipeline blockage caused by the fact that the negative-pressure system terminal component sucks excessive liquid.
