[0048] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] As attached Figure 1 As shown, the assembly of the breathing circuit connector in the prior art is to first insert the fixed rubber part into the threaded tube 1, and then sleeve it on the threaded tube 1 through two semicircular bushings 4, and then form the appearance connector 2 through a secondary injection molding process. However, after the appearance connector 2 is assembled, the threaded tube 1 needs to be placed in the injection molding machine manually or with an auxiliary machine, and wait for a certain period of time for injection molding, resulting in a long time and inability to produce quickly. Generally, the injection molded appearance connector 2 will completely wrap the fixed rubber part, and some will injection mold the appearance connector 2 on the outer wall of the fixed rubber part, and then set an adhesive solvent between the fixed rubber part and the threaded tube 1 to seal the fixed rubber part and the threaded tube 1. However, the use of the adhesive solvent will also cause its volatiles to accumulate in the semi-enclosed space, causing safety risks.

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

[0053] As attached Figure 2 , Attachment Figure 3 and attached Figure 4As shown, a breathing circuit connector with a heating wire comprises a threaded tube 1, an appearance connector 2, a soft rubber sleeve 3, two semicircular bushings 4 and a locking sleeve 5; the threaded tube 1 is a connecting tube, the bottom of the appearance connector 2 is arranged inside the threaded tube 1, and is used to connect with the threaded tube 1, and the outer side of the threaded tube 1 is sleeved with a soft rubber sleeve 3, and the position of the soft rubber sleeve 3 sleeved on the threaded tube 1 corresponds to the appearance connector 2 located in the threaded tube 1, and the outer side of the soft rubber sleeve 3 is sleeved with two semicircular bushings 4, and the two semicircular bushings 4 cooperate to form a ring, and the two semicircular bushings 4 can move relative to each other to squeeze the soft rubber sleeve 3 and the threaded tube 1, and can also move away from the soft rubber sleeve 3, and the two semicircular bushings 4 The outer sleeve is provided with a locking sleeve 5, which abuts against the two semicircular bushings 4 to squeeze the semicircular bushings 4 and the soft rubber sleeve 3, so that the threaded tube 1 fixes the appearance joint 2; by arranging the soft rubber sleeve 3 inside the two semicircular bushings 4, and the two semicircular bushings 4 can move relatively, so that the locking sleeve 5 squeezes the two semicircular bushings 4, and the two semicircular bushings 4 move toward each other, further squeezing the soft rubber sleeve 3 and the threaded tube 1, so that the appearance joint 2 is firmly fixed in the threaded tube 1.
