As shown in fig. 1, the water collecting cup for the breathing machine pipeline comprises a three-way pipe 1 and a water collecting assembly, wherein the three-way pipe 1 comprises an air flow pipeline 11 and a condensation pipeline 12, the three-way pipe is of a Y-shaped or T-shaped structure, and preferably is a Y-shaped three-way pipe so as to collect condensed water. The subassembly that catchments is including dismantling cup 3 and the bowl cover 2 of connection, and cup 3 adopts the preparation of transparent rigid plastic material to form, conveniently observes inside 3 cups. The top of bowl cover 2 with condensation duct 12 connects, the top surface outside of bowl cover 2 be equipped with to the sunken water conservancy diversion chamber 23 that forms of 3 directions of cup, water conservancy diversion chamber 23's diameter is from last down reducing gradually, and water conservancy diversion chamber 23 can be that the frustum shape is hourglass hopper-shaped, taper or bowl cup, and in this embodiment, preferred water conservancy diversion chamber 23 is that the frustum shape is hourglass hopper-shaped. A through hole 231 is formed in the center of the bottom of the flow guide cavity 23; be equipped with mobilizable inner core 4 in the water conservancy diversion chamber 23, the inner core is including spring 41, movable plug 42 and the movable rod 43 that from top to bottom connects gradually the setting, spring 41's upper end with bowl cover 2 is connected, movable plug 42 with the bottom in water conservancy diversion chamber 23 matches movable butt, the lower extreme of movable rod 43 stretches out outside through-hole 231, the bottom activity of cup 3 is provided with the top and pushes away the thimble 5 of movable rod 43 and be equipped with control thimble 5 and push away the control assembly 6 of high, so that movable plug 42 with form the rivers clearance of adjustable size between the water conservancy diversion chamber 23. Because the diameter of the flow guide cavity 23 is gradually reduced from top to bottom, when the thimble 5 pushes the movable rod to drive the movable plug 42 to move upwards, the gap between the movable plug 42 and the flow guide cavity 23 is gradually increased along with the difference of the upward moving height of the movable plug 42, so that the size of the water flow gap between the two types is adjusted, and the condensed water in the connecting pipeline of the breathing machine is easy to flow into the cup quickly when more water is collected in the cup body.

The control assembly comprises a sleeve 61 and a sealing plug 62 arranged in the sleeve 61, the bottom of the cup body 3 is integrally formed with a connecting pipe 31, the inner wall of the sleeve 61 is integrally formed with an internal thread, the outer wall of the connecting pipe 31 is integrally formed with an internal thread screwed with the external thread, the lower end of the sealing plug 62 is connected with the sleeve 61, the upper end of the sealing plug 62 is movably and hermetically connected with the connecting pipe 31, and the top of the sealing plug 62 is fixed with the thimble 5. Preferably, the connecting tube 31 and the sleeve 61 are made of a transparent rigid plastic to facilitate the observation of the movement of the sealing plug. When pushing the movable rod 43, as shown in fig. 2, the sleeve 61 is rotated to move upward, so that the thimble 5 pushes the movable rod 43 to drive the movable plug 42 to move upward along with the upward movement, the spring 41 contracts, and the upward moving height of the movable plug 42 is controlled by controlling the upward moving height of the sleeve 61, thereby realizing the adjustment of the size of the water flow gap.

In order to facilitate the outflow of the condensed water in the cup body 3, as shown in fig. 4, a stepped groove 63 penetrating the interior of the sleeve 61 is formed at the lower end of the sleeve 61, three spokes 64 extending from the center to the peripheral wall and evenly distributed in the circumferential direction are fixedly arranged in the stepped groove 63, and the centers of the three spokes 64 are connected with the center of the bottom end of the sealing plug 62. When water in the cup body 3 needs to be drained, as shown in fig. 3, the sleeve 61 is rotated to move downwards to drive the sealing plug 62 and the ejector pin 5 to move downwards, so that the ejector pin 5 gradually moves from the state of pushing the movable rod 43 to the state of not pushing the movable rod 43 and then transitions to the state of separating from the movable rod 43, when the ejector pin 5 is separated from the movable rod 43 and the sealing plug 62 is separated from the connecting pipe 31, the movable plug 42 clings to the flow guide cavity 23 under the elastic force of the spring 41 without being pushed, so that the through hole 231 of the flow guide cavity 23 is sealed, and the connecting pipe 31 is communicated with the outside through the stepped groove 63, so that condensed water in the cup body 3 is drained, and because the through hole 231 is in a sealed state in the water draining process, air leakage of a breathing pipeline is avoided, and safety is improved. In addition, the outer side wall of the sleeve 61 is provided with vertical bar skidproof grains 611, so that the sleeve 61 can be rotated to avoid skidding in the rotating process.

The cup cover 2 is clamped with the cup body 3. In the novel use, the cup cover 2 comprises an inner layer 21 and an outer layer 22, a gap for clamping the cup body 3 is formed between the inner layer 21 and the outer layer 22, a plurality of clamping holes 221 are circumferentially formed in the outer layer 22, the inner wall of the outer layer 22 corresponds to the limiting protrusions 222 arranged below the clamping holes 221, and a clamping sheet 32 clamped with the clamping holes 221 is circumferentially arranged on the outer wall of the upper end of the cup body 3. When the cup body 3 is covered with the cup cover 2, the cup body 3 is inserted into the gap between the inner layer 21 and the outer layer 22 and then rotates for a certain angle, so that the clamping sheet 32 on the outer wall of the cup body 3 is clamped in the clamping hole 221 after rotating for a certain angle, and the cup body 3 and the cup cover 2 are clamped. The novel cup body 3 and the cup cover 2 can also be detachably connected in a threaded connection mode, and no specific limitation is made here.

The use principle of the utility model is as follows: the cup body 3 is inserted into the gap between the inner layer 21 and the outer layer 22 of the cup cover 2, and the clamping sheet 32 is clamped in the clamping hole 221 and clamped with the cup cover 2 after the cup body 3 is rotated for a certain angle. The sleeve 61 is rotated to move the sleeve 61 upwards, the thimble 5 is driven to push the movable rod 43 upwards, the movable plug 42 moves upwards, the spring 41 is compressed, a water flow gap is formed between the movable plug 42 and the inner wall of the diversion cavity 2, and the sleeve 61 controls the upward moving height of the movable plug 42, so that the size of the water flow gap can be adjusted. The condensed water produced on the breathing machine pipeline flows into the cup body 3 through the water flow gap, thereby realizing the collection of the condensed water. When the water flow gap is too small in use, and condensed water with slow water flow cannot effectively fall into the cup to cause water accumulation at the upper part, the thimble 5 pushes the movable rod 43 to drive the movable plug 42 to move upwards to enlarge the water flow gap by rotating the sleeve 61 to move upwards. When the condensed water in the cup body 3 needs to be discharged, the sleeve 61 is screwed to the lower end to separate the sealing plug 62 in the sleeve 61 from the connecting pipe 31, so that the connecting pipe 31 is communicated with the outside through the stepped groove 63, the condensed water can be discharged, and the through hole 231 is in a closed state in the water discharging process, so that the air leakage of a breathing pipeline is avoided, and the safety is improved.
