[0051] As shown in Figure 1, the assembly of the breathing circuit connector in the prior art is to insert the fixing glue into the threaded pipe 1, then set the two half-round bushings 4 on the threaded pipe 1, and then form the appearance connector 2 through the process of secondary injection molding, but the appearance connector 2 needs to be put into the injection molding machine by manual or auxiliary mechanical after assembly, and wait for a certain time for injection molding, which leads to a long time and cannot be produced quickly; the general injection molding appearance connector 2 will completely wrap the fixing glue, and some will inject the appearance connector 2 on the outer wall of the fixing glue, and then set the adhesive solvent between the fixing glue and the threaded pipe 1 to seal the fixing glue and the threaded pipe 1, but the use of the adhesive solvent will also cause the volatile matter to accumulate in the semi-closed space, causing safety risks.

[0052] In view of the deficiencies of the prior art, the present embodiment provides a breathing circuit connector with heating wire, which can be specifically referred to as follows:

[0053] As shown in FIG. 2, FIG. 3 and FIG. 4, a breathing circuit joint with heating wire includes a threaded pipe 1, an appearance joint 2, a soft rubber sleeve 3, two half-round bushings 4 and a lock sleeve 5; the threaded pipe 1 is a connecting pipe, the bottom of the appearance joint 2 is arranged inside the threaded pipe 1, used for connecting with the threaded pipe 1, and the outside of the threaded pipe 1 is sleeved with the soft rubber sleeve 3, the position of the soft rubber sleeve 3 sleeved on the threaded pipe 1 corresponds to the appearance joint 2 inside the threaded pipe 1, the outside of the soft rubber sleeve 3 is sleeved with the two half-round bushings 4, the two half-round bushings 4 are matched to form a sleeve ring, the two half-round bushings 4 can relatively move to extrude the soft rubber sleeve 3 and the threaded pipe 1, and can move away from the soft rubber sleeve 3, the outside of the two half-round bushings 4 is sleeved with the lock sleeve 5, the lock sleeve 5 abuts against the two half-round bushings 4 to extrude the half-round bushings 4 and the soft rubber sleeve 3, so that the threaded pipe 1 fixes the appearance joint 2; by arranging the soft rubber sleeve 3 inside the two half-round bushings 4 and the two half-round bushings 4 being relatively movable, the extrusion of the lock sleeve 5 to the two half-round bushings 4 is realized, the two half-round bushings 4 move towards each other to further extrude the soft rubber sleeve 3 and the threaded pipe 1, so that the appearance joint 2 is fixed in the threaded pipe 1, the above device is not only convenient and simple, but also, compared with the prior art, the breathing circuit joint does not need to be secondarily injection molded, can be directly assembled and produced, and the production efficiency is effectively improved.

[0054] Specifically, first, the soft rubber sleeve 3 is fitted onto the threaded pipe 1. The soft rubber sleeve 3 can be either an interference fit or a transition fit with the threaded pipe 1, so that the soft rubber sleeve 3 is fitted onto one end of the threaded pipe 1 to correspond to the external connector 2 set inside the threaded pipe 1. Then, the locking sleeve 5 is fitted onto the threaded pipe 1, located at the bottom of the soft rubber sleeve 3. Next, one end of the external connector 2 is inserted into the threaded pipe 1. Then, two semi-circular bushings 4 are fitted onto the outer surface of the soft rubber sleeve 3. The two semi-circular bushings 4 have positioning components that can position the two semi-circular bushings 4. Under the action of the positioning components, the two semi-circular bushings 4 can move relative to each other. Finally, the locking sleeve 5 is pulled upward. In the initial state, the bottom of the two semi-circular bushings 4 is chamfered, and the top wall of the locking sleeve 5 is... Holding the chamfered edge, the two semi-circular bushings 4 are moved towards each other under the action of the chamfer until the locking sleeve 5 is fitted onto the outer wall of the two semi-circular bushings 4 and squeezes and limits the two semi-circular bushings 4. The two semi-circular bushings 4 fix the soft rubber sleeve 3 and the threaded sleeve, thereby achieving the function of fixing the appearance joint 2 and the threaded tube 1. At the same time, both the soft rubber sleeve 3 and the threaded tube 1 are made of soft material, and under the action of the soft rubber sleeve 3 and the semi-circular bushings 4, the threaded tube 1 and the appearance joint 2 can achieve a sealing effect. Compared with the sealing method of the prior art by adhesive solvent, the sealing method of this application can prevent the volatiles of adhesive solvent from accumulating in the semi-enclosed space, and reduce the risk of VOC (volatile organic compounds) and related E&L (extractable and leachable) during installation and secondary injection molding.

[0055] In this embodiment, as shown in Figures 2 and 3, a threaded post 11 is arranged around the outer side of the threaded tube 1. The hardness of the threaded post 11 is greater than the hardness of the inner wall of the threaded tube 1, and a heating wire 12 is arranged inside the threaded post 11. By connecting the heating wire 12 to an external power source, the threaded tube 1 can be heated through the heating wire 12 to achieve the effect during use.

[0056] In this embodiment, as shown in Figure 8, the semicircular bushing 4 is provided with a threaded groove 41 inside. The two semicircular bushings 4 cooperate to form an annular coiled threaded groove 41, and the threaded groove 41 cooperates with the threaded post 11 to facilitate the fixing of the semicircular bushing 4. At the same time, it can also prevent the semicircular bushing 4 from detaching from the outer surface of the threaded tube 1 under the action of the locking sleeve 5.

[0057] In this embodiment, as shown in Figure 8, the two semicircular bushings 4 are the left bushing 42 and the right bushing 43, respectively. The left bushing 42 is provided with a positioning hole 421 on the side near the right bushing 43, and the right bushing 43 is provided with a positioning rod 431 on the side near the left bushing 42. When the left bushing 42 and the right bushing 43 are fitted on the outside of the soft rubber sleeve 3, the positioning rod 431 is inserted into the positioning hole 421, so that the left bushing 42 and the right bushing 43 cooperate, and under the action of the positioning rod 431 and the positioning hole 421, the two can move relative to each other.

[0058] In this embodiment, as shown in Figure 5, an annular baffle 21 is provided on the outer side of the external connector 2.

The two semi-circular bushings 4 are positioned by the threaded post 11, and the two semi-circular bushings 4 can limit the locking sleeve 5. At the same time, the annular baffle 21 abuts against the top wall of the threaded tube 1 and is connected to the locking sleeve 5 by the bottom wall of the annular baffle 21. This allows the external connector 2 to be firmly fixed inside the threaded tube 1, effectively preventing the external connector 2 from detaching from the threaded tube 1 under external force.

[0059] Furthermore, a first connecting cylinder is provided at the bottom of the annular baffle 21, and a second connecting cylinder is provided at the top of the annular baffle 21.

[0060] Furthermore, as shown in Figure 6, the locking sleeve 5 includes a sleeve and a fixing plate. The sleeve is fitted on the outside of the two semi-circular bushings 4, and the fixing plate is located at the bottom of the sleeve. The center of the fixing plate has a slot, which is smaller than the diameter of the sleeve and smaller than the diameter of the annular bushing formed by the two semi-circular bushings 4, so that the top wall of the fixing plate abuts against the bottom wall of the semi-circular bushing 4. The locking sleeve 5 is limited by the positioning of the semi-circular bushings 4 and the threaded post 11.

[0061] Furthermore, the top of the sleeve is provided with a conical support portion, which supports the annular baffle 21. The conical support portion and the annular baffle 21 are fused together by ultrasonic welding, and the locking sleeve 5 is fixed and sealed to the external connector 2.

A conductive copper sheet 53 is provided inside the connecting part 52. The conductive copper sheet 53 is connected to the heating wire 12, and a plug 54 is connected to one end of the connecting part 52. The PIN pin 544 inside the plug 54 is connected to the conductive copper sheet 53. The plug 54 is connected to an external power plug 54 to supply power to the heating wire 12.

[0064] Specifically, the top of the semi-circular bushing 4 corresponding to the connecting part 52 is provided with a slot, which can be used for the heating wire 12 to pass through, so as to facilitate the connection between the heating wire 12 and the conductive copper sheet 53.

The positioning post 523 is disposed in the receiving groove 522. One end of the positioning post 523 is disposed on the outer surface of the lock sleeve 5. The conductive copper sheet 53 is provided with a plurality of positioning holes 421. The positioning holes 421 cooperate with the positioning post 523 so that the conductive copper sheet 53 is disposed in the receiving groove 522, and it is also convenient for the PIN pin 544 to connect with the conductive copper sheet 53. At the same time, the positioning post 523 is a heat-fused post. By heating the positioning post 523 to a molten state, the conductive copper sheet 53 can be fixed to the connecting part 52.

[0066] In this embodiment, as shown in Figure 7, the plug 54 includes a mating groove plate 541 and a plug tube 543. The mating groove plate 541 is used to include a positioning groove plate 521, which not only serves as a guide and positioning but also connects to the connecting part 52.

The first positioning groove 51 penetrates the lock sleeve 5 and the positioning groove plate 521, thereby forming an opening at the top of the positioning groove plate 521. The second positioning block 542 cooperates with the first positioning groove 51 so that the mating groove plate 541 and the positioning groove plate 521 achieve a positioning function, which facilitates the installation and connection of the two. A plug tube 543 is also provided on the side of the mating groove plate 541 away from the lock sleeve 5. The plug tube 543 has two insertion holes inside, and a PIN pin 544 is provided in the insertion hole. One end of the PIN pin 544 is connected to the conductive copper sheet 53.

[0067] Furthermore, there are two conductive copper sheets 53, and the two conductive copper sheets 53 are respectively connected to two PIN pins 544.
