A respiratory tube assembly includes a three-way connector having first to third connecting sections, a container defining a receiving chamber and having a container surrounding wall and a projection projecting into the receiving chamber, a cover connected to the third connecting section and including a tubular recess, a recess bottom wall having a water-discharge opening, and an outer surrounding wall engaged detachably to the container surrounding wall, a valve head disposed movably within the tubular recess, and a valve rod extending into the receiving chamber. The valve head abuts against the third connecting section when the valve rod abuts against the projection so that the tubular recess communicates fluidly with the receiving chamber through the water-discharge opening. An inner tubular unit extends through the first and second connecting sections.

1. A respiratory tube assembly comprising: an outer tubular unit and an inner tubular unit, said outer tubular unit including a first three-way connector, a first tubular sleeve, a second tubular sleeve, and a water-collecting device;said first three-way connector having a first main tubular section
1. A respiratory tube assembly comprising: an outer tubular unit and an inner tubular unit, said outer tubular unit including a first three-way connector, a first tubular sleeve, a second tubular sleeve, and a water-collecting device;said first three-way connector having a first main tubular section, first and second connecting sections extending outwardly and respectively from two opposite ends of said first main tubular section and extending in two opposite directions along an axis of said first main tubular section, and a third connecting section extending from said first main tubular section between said first and second connecting sections along a direction transverse to said axis, each of said first, second, and third connecting sections having a diameter smaller than that of said first main tubular section;said first tubular sleeve having a first end portion sleeved on said first connecting section, and a second end portion opposite to said first end portion;said second tubular sleeve having a third end portion sleeved on said second connecting section, and a fourth end portion opposite to said third end portion;said water-collecting device including a container, and a cover covering said container and connected to said third connecting section, said container being connected detachably to said cover and having a container bottom wall, a container surrounding wall extending upwardly from and cooperating with said container bottom wall to define a receiving chamber, and a projection projecting from said container bottom wall into said receiving chamber, said cover including a top wall that is recessed downwardly to form a tubular recess, a recess surrounding wall surrounding said tubular recess, a recess bottom wall connected to said recess surrounding wall oppositely of said top wall, and an outer surrounding wall extending downwardly from an outer end periphery of said top wall, surrounding said recess surrounding wall, and engaged detachably to said container surrounding wall, said recess bottom wall extending into said receiving chamber and having a water-discharge opening;said water-collecting device further including a valve member that has a valve head disposed movably within said tubular recess, and a valve rod extending downwardly from said valve head into said receiving chamber through said water-discharge opening to abut against said projection, said valve head being spaced apart from said recess bottom wall and abutting against said third connecting section when said valve rod abuts against said projection so that said tubular recess communicates fluidly with said receiving chamber through said water-discharge opening;said inner tubular unit extending from said first tubular sleeve into said second tubular sleeve through said first and second connecting sections and said first main tubular section of said first three-way connector, and having a fifth end portion proximate to said second end portion, and a sixth end portion proximate to said fourth end portion. 2. The respiratory tube assembly of claim 1, wherein said outer tubular unit further includes an air-discharge tube, and a second three-way connector having a second main tubular section aligned axially with said first main tubular section, first and second connecting sections extending outwardly and respectively from two opposite ends of said second main tubular section and extending in two opposite directions along an axis of said second main tubular section, a third connecting section extending from said second main tubular section between said first and second connecting sections of said second three-way connector along a direction transverse to said axis of said second main tubular section and connected to said air-discharge tube, and an inner tube connected to said first connecting section of said second three-way connector and extending into said second main tubular section, said second end portion being connected to said second connecting section of said second three-way connector, said fifth end portion extending into said second main tubular section and connecting said inner tube of said second three-way connector. 3. The respiratory tube assembly of claim 1, wherein said outer tubular unit further includes a coupling element having an outer tube connected to said fourth end portion, and an inner tube disposed coaxially in said outer tube and connected to said sixth end portion.
