[0048] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0049] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] As attached Figure 1 As shown, in the prior art, the assembly of the breathing circuit connector involves first inserting the fixing component into the threaded tube 1, then fitting two semi-circular bushings 4 onto the threaded tube 1, and finally forming the external connector 2 through a secondary injection molding process. However, after assembly, the threaded tube 1 needs to be manually or mechanically placed into the injection molding machine and allowed to wait for a certain period of time for injection molding, resulting in a long production time and hindering rapid production. Generally, the injection-molded external connector 2 completely encloses the fixing component, or sometimes it is injection-molded onto the outer wall of the fixing component. Then, an adhesive solvent is placed between the fixing component and the threaded tube 1 to seal them. However, the use of adhesive solvent can also cause its volatiles to accumulate in the semi-enclosed space, posing a safety risk.

[0052] In view of the shortcomings of the prior art, this embodiment provides a breathing circuit connector with a heating wire, as described below:

[0053] As attached Figure 2 Appendix Figure 3 and attached Figure 4As shown, a heating wire breathing circuit connector includes a threaded tube 1, an external connector 2, a soft rubber sleeve 3, two semi-circular bushings 4, and a locking sleeve 5. The threaded tube 1 is a connecting tube. The bottom of the external connector 2 is located inside the threaded tube 1 for connection with the threaded tube 1. The soft rubber sleeve 3 is fitted on the outside of the threaded tube 1, and its position corresponds to that of the external connector 2 located inside the threaded tube 1. Two semi-circular bushings 4 are fitted on the outside of the soft rubber sleeve 3. The two semi-circular bushings 4 cooperate to form a collar. The two semi-circular bushings 4 can move towards each other to compress the soft rubber sleeve 3 and the threaded tube 1, or they can move away from each other to detach from the soft rubber sleeve 3. An external locking sleeve 5 is provided, which abuts against two semi-circular bushings 4 to compress the semi-circular bushings 4 and the soft rubber sleeve 3, thereby fixing the threaded tube 1 to the external connector 2. By providing the soft rubber sleeve 3 inside the two semi-circular bushings 4 and allowing the two semi-circular bushings 4 to move relative to each other, the locking sleeve 5 compresses the two semi-circular bushings 4. The two semi-circular bushings 4 move towards each other, further compressing the soft rubber sleeve 3 and the threaded tube 1, so that the external connector 2 is firmly fixed inside the threaded tube 1. The above device is not only convenient and simple, but also, compared with the prior art, this breathing circuit connector does not require secondary injection molding and can be directly assembled and produced, effectively improving production efficiency.

[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 the appendix Figure 2 and attached Figure 3 As shown, 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 the appendix Figure 8 As shown, the semicircular bushing 4 has 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 the appendix Figure 8As shown, 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 the appendix Figure 5 As shown, an annular baffle 21 is provided on the outer side of the external connector 2. The annular baffle 21 abuts against the top wall of the threaded tube 1 and is connected to the locking sleeve 5. 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. The diameter of the first connecting cylinder is smaller than that of the second connecting cylinder, and the first connecting cylinder is connected to the second connecting cylinder. The first connecting cylinder is used to be placed inside the threaded pipe 1, and the annular baffle 21 abuts against the threaded pipe 1. The second connecting cylinder is used to connect with external components.

[0060] Further details are attached. Figure 6 As shown, 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.

[0062] In one embodiment of this application, a first positioning block 22 is provided at the bottom of the annular baffle 21, and a first positioning groove 51 is provided at the top of the locking sleeve 5. The first positioning block 22 and the first positioning groove 51 cooperate to facilitate the positioning between the external connector 2 and the locking sleeve 5 and to facilitate subsequent welding.

A conductive copper sheet 53 is provided inside the connecting part 52. The conductive copper sheet 53 is connected to the heating wire 12.

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.

[0065] In this embodiment, the connecting part 52 includes a positioning groove plate 521 and a positioning post 523.

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 the appendix Figure 7 As shown, 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 tool, but also connects to the connecting part 52. A second positioning block 542 is provided on the inner wall of the mating groove plate 541, and a first positioning groove 51 on the lock sleeve 5 penetrates the positioning groove plate 521. 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.

[0068] Furthermore, the inner wall of the mating groove plate 541 abuts against the positioning groove plate 521, and the mating groove plate 541 and the locking sleeve 5 are ultrasonically fixed; at the same time, the mating groove plate 541 and the positioning groove plate 521 can also be ultrasonically fixed to increase the stability of the plug 54 and the connecting part 52.

[0069] Furthermore, the top and bottom of the mating groove plate 541 are provided with clearance slots, which cooperate with the annular baffle 21 and the fixing plate of the locking sleeve 5.

[0075] Furthermore, a stop block is provided at the bottom of the annular baffle 21. The stop block cooperates with the conductive copper sheet 53 to limit the position of the conductive copper sheet 53 so as to prevent the conductive copper sheet 53 from shifting when the hot melt column 23 is in a molten state.
