Abstract
Description
Technical Field
[0001] This application relates to the field of manufacturing jigs for breathing circuits, and in particular to a multi-wire heating wire processing mold and a multi-wire heating wire breathing circuit processing mold. Background Technology
[0002] Currently, multi-wire heating breathing circuits are widely used in the medical device field to heat and maintain the temperature of delivered gas, improving patient breathing comfort and treatment efficacy. In the production of multi-wire heating breathing circuits, multiple heating wires or auxiliary signal wires are typically pre-embedded in the spiral diaphragm of the circuit, requiring each wire to maintain a stable alignment to ensure reliable electrical connections and overall circuit flexibility. To achieve synchronous embedding of multiple wires, existing technologies commonly employ a mold insert located inside the spiral diaphragm's extrusion nozzle. This insert guides the wires and plastic diaphragm to be extruded synchronously, forming the multi-wire heating breathing circuit product.
[0003] However, most existing multi-wire positioning mold inserts adopt a single-hole centralized wire inlet and unguided arrangement, which makes it easy for multiple wires to become disordered and have uncontrollable spacing during the molding process. Since the wires cannot maintain a good distribution inside the helical bone, they are prone to contact with each other, leading to the risk of short circuits. In addition, some wires may detach from the periosteum and be exposed to the outside air during extrusion, affecting the mechanical performance and electrical safety of the breathing circuit.
[0004] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a multi-wire heating wire processing mold and a multi-wire heating wire breathing circuit processing mold, which aims to solve the problem in the prior art of ensuring that the wires are stably positioned in the spiral periosteum and avoiding short circuits between the wires.
[0006] The technical solution adopted by this application to solve the technical problem is as follows: a multi-wire heating wire processing mold for a breathing circuit, used to pre-embed wires in the breathing circuit, wherein the multi-wire heating wire processing mold includes a dispensing nozzle and a positioning insert detachably connected to the dispensing nozzle. The dispensing nozzle has a dispensing section with a glue inlet. The positioning insert has multiple spaced positioning channels. A dispensing channel communicating with the glue inlet is provided between the positioning insert and the dispensing section. Multiple wires pass through the multiple positioning channels one by one, enter the dispensing channel at preset intervals, and exit the dispensing channel after being wrapped with molten glue.
[0007] Optionally, the positioning insert includes an insert body, the insert body having an integrally formed fixed section and a reduced diameter section, a plurality of positioning channels passing through the fixed section and the reduced diameter section, the positioning channels having a wire inlet and a wire outlet, the wire inlet being located at one end of the fixed section away from the reduced diameter section, and the wire outlet being located at one end of the reduced diameter section away from the fixed section.
[0008] The hot nozzle includes a connecting section integrally formed with the dispensing section. The glue inlet is opened between the connecting section and the dispensing section. A through hole is opened in the dispensing section and the connecting section. The through hole has a fixing hole section and a dispensing hole section. The fixing section and the fixing hole section are detachably connected. The dispensing channel is formed by the fitting clearance between the dispensing hole section and the diameter reduction section.
[0009] Optionally, the lines connecting the cross sections of the plurality of positioning channels can form a trapezoid, rectangle, parallelogram, or straight line.
[0010] Optionally, the spacing between the plurality of positioning channels is set to be equidistant and / or unequal.

[0016] The technical solution adopted by this application to solve the technical problem is as follows: a multi-wire heating wire breathing circuit processing mold, which includes the multi-wire heating wire processing mold as described above.
[0017] Compared with existing technologies, this application provides a multi-wire heating wire processing mold and a multi-wire heating wire breathing circuit processing mold. The multi-wire heating wire processing mold for the breathing circuit achieves clear guidance and effective positioning of multiple wires before they enter the dispensing channel by setting a positioning insert with multiple spaced positioning channels inside the dispensing nozzle. Specifically, by threading the wires one-to-one into the multiple positioning channels, each wire maintains a stable preset spacing distribution before entering the molten adhesive coating. This overcomes the problems of chaotic arrangement and uncontrollable spacing caused by concentrated wire entry in existing technologies, ensuring that the wires are stably and orderly distributed inside the spiral membrane. This effectively prevents the risk of short circuits caused by contact between wires and avoids the phenomenon of wires detaching from the membrane and being exposed to the outside air, significantly improving the electrical safety and mechanical performance of the breathing circuit product. Simultaneously, the detachable structure of the positioning insert allows for flexible replacement according to wire specifications and functional requirements, facilitating effective zoning of different wires. This benefits subsequent processing and welding processes, thereby improving production efficiency and product consistency, reducing production costs, and enhancing overall product quality and market competitiveness.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] To prevent cold airflow from irritating patients' respiratory tracts, heated breathing tubing is often installed between medical equipment (such as ventilators, humidifiers, and oxygen concentrators) and the user's mouth to heat the airflow passing through it. To meet this requirement, heating wires need to be wound simultaneously during the fabrication of the breathing circuit. Multiple heating or communication wires are often required to ensure heating and communication needs are met. When insulation between multiple heating or communication wires is necessary, insulating glue must be filled between them, and the wires also need to be insulated to prevent electric shock to medical staff and patients. However, most existing multi-wire positioning mold inserts use a single-hole centralized wire entry method with no clear guidance, making it easy for multiple wires to become disordered and have uncontrollable spacing during the molding process. Because the wires cannot maintain a good distribution inside the spiral bone, they are prone to contact with each other, leading to a short circuit risk. Furthermore, some wires may detach from the periosteum and be exposed to external air during extrusion, affecting the mechanical performance and electrical safety of the breathing circuit. Furthermore, wires with different functions or specifications cannot be effectively arranged in partitions in existing molds, which is not conducive to subsequent processing and welding processes, and reduces production efficiency and product consistency.
[0032] Please refer to the following: Figures 1 to 6 The first embodiment of this application provides a multi-wire heating wire processing mold 10 for pre-embedding wires in a breathing circuit. The multi-wire heating wire processing mold 10 includes a dispensing nozzle 20 and a positioning insert 30. The positioning insert 30 is detachably connected to the interior of the dispensing nozzle 20. The positioning insert 30 has multiple spaced positioning channels 31, each positioning channel 31 used to position and guide a wire. The dispensing nozzle 20 has a dispensing section 21 with a glue inlet 22. A dispensing channel 40 communicating with the glue inlet 22 is provided between the positioning insert 30 and the dispensing section 21. Molten glue enters the dispensing section 21 from the glue inlet 22 and enters the dispensing channel 40. Multiple wires pass through the multiple positioning channels 31 one by one, enter the dispensing channel 40 at preset intervals, and are then wrapped and isolated by the molten glue. After being wrapped by the molten glue, they all exit the dispensing channel 40.
[0033] It is understandable that the multi-wire heating wire processing mold 10, by setting a positioning insert 30 with multiple spaced positioning channels 31 inside the glue dispensing nozzle 20, achieves clear guidance and effective positioning of multiple wires before entering the glue dispensing channel 40. Specifically, by threading the wires one-to-one into the multiple positioning channels 31, each wire maintains a stable preset spacing distribution before entering the molten glue encapsulation, thus overcoming the problems of chaotic arrangement and uncontrollable spacing caused by concentrated wire entry in the prior art. This ensures that the wires can be stably and orderly distributed inside the spiral membrane, effectively preventing the risk of short circuits caused by contact between wires, and avoiding the phenomenon of wires detaching from the membrane and being exposed to the outside air, significantly improving the electrical safety and mechanical performance of the breathing circuit product. At the same time, the detachable structure of the positioning insert 30 allows for flexible replacement according to wire specifications and functional requirements, facilitating the effective zoning arrangement of different wires, which is beneficial to subsequent processing and welding processes, thereby improving production efficiency and product consistency, reducing production costs, and enhancing the overall product quality and market competitiveness.
[0034] In some embodiments, the positioning insert 30 includes an insert body 32, which specifically includes an integrally formed fixed section 33 and a reduced-diameter section 34, with multiple positioning channels 31 extending through the fixed section 33 and the reduced-diameter section 34. Each positioning channel 31 is provided with a wire inlet 311 and a wire outlet 312, wherein the wire inlet 311 is located at the end of the fixed section 33 opposite to the reduced-diameter section 34, and the wire outlet 312 is located at the end of the reduced-diameter section 34 opposite to the fixed section 33. Through this structural design, multiple wires can be accurately introduced from the multiple wire inlets 311 on the end face of the fixed section 33, and then guided by the positioning channels 31 to be accurately exited from the multiple wire outlets 312 on the end face of the reduced-diameter section 34. This segmented guiding structure allows the wire to be clearly guided and positioned at a preset distance before entering the molten adhesive wrapping, effectively avoiding the chaotic wire arrangement and short circuit risks caused by single-hole centralized wire entry in the prior art. It ensures the stable and orderly distribution of the wire in the circuit and improves the electrical connection reliability and mechanical flexibility of the breathing circuit product.
[0035] Furthermore, the hot nozzle 20 in this embodiment further includes a connecting section 23 integrally formed with the dispensing section 21. An inlet 22 is disposed between the connecting section 23 and the dispensing section 21, allowing molten adhesive to efficiently enter the dispensing channel 40 of the dispensing section 21 through the inlet 22. A through hole 24 is provided in both the connecting section 23 and the dispensing section 21. The through hole 24 has a fixing hole section 241 and a dispensing hole section 242. The fixing hole section 241 is detachably connected to the fixing section 33 of the insert body 32, making the assembly and disassembly of the insert simple and quick, greatly improving the convenience and flexibility of mold maintenance. The stable connection between the fixing section 33 and the fixing hole section 241 also ensures the stability of the positioning insert 30 within the mold, avoiding the risk of uneven or deviated wire arrangement due to accidental displacement of the positioning insert 30 during processing.
[0036] Meanwhile, the glue outlet channel 40 is achieved through the fitting gap formed between the glue outlet section 242 and the diameter reduction section 34. This fitting gap structure design ensures that the molten glue can evenly wrap the outgoing wire, so that each wire is evenly covered by molten glue in the glue outlet channel 40 and forms a stable and reliable embedding structure. This completely solves the safety hazard problem of wires being exposed or detached from the periosteum in the prior art, and ensures the electrical insulation performance and overall mechanical strength of the product.
[0037] Therefore, this embodiment, through the above-described structural design, achieves clear positioning and guidance of multiple wires, stable spacing arrangement, and efficient melt coating, effectively overcoming problems such as unstable wire arrangement, uncontrolled spacing, and exposed short circuits in existing technologies. Simultaneously, the modular design and detachable connection method of the structure significantly optimize the production efficiency and maintenance convenience of the mold, improving the processing quality, consistency, and market competitiveness of the breathing circuit products.
[0038] Please refer to further details. Figure 7 and Figure 8 In some embodiments, the connection of the cross sections of the respective positioning channels 31 can be specifically designed as trapezoidal (e.g., Figure 7 (c) and Figure 8 (i) in the middle), rectangle (e.g.) Figure 7 (b) and Figure 8 (h) in the middle), parallelogram (e.g.) Figure 7 (a) or linear (e.g.) Figure 7 (d) Figure 7 (e) Figure 7 (f) and Figure 8The (g) structure in the text. Through positioning channels 31 with different cross-sectional shapes, a more flexible and stable positioning guide structure can be provided according to the wire type, size, and processing requirements. For example, using trapezoidal or parallelogram cross-sections can better adapt to the outer contour of wires of different shapes, further ensuring that the wire maintains a stable position during positioning, preventing wire offset or flipping, thereby improving the accuracy and reliability of wire processing. Furthermore, the number of positioning channels 31 is set to 2 or 4 (e.g., Figure 7 (a) Figure 7 (b) Figure 7 (c) Figure 7 (d) Figure 7 (e) and Figure 7 (f) or 6 (e.g.) Figure 8 (g) in Figure 8 (h) and Figure 8 (i) etc.
[0039] In some preferred embodiments, the spacing between the positioning channels 31 can be set at equal intervals (e.g. Figure 7 (a) Figure 7 (b) Figure 7 (e) Figure 8 (h) and Figure 8 (i) and / or the distance setting ( Figure 7 (c) Figure 7 (d) in section 8 and (g) in section 8). When the spacing between the positioning channels 31 is the same, it helps to simplify the design of the wire layout, is suitable for parallel processing of multiple wires with the same specifications, and improves the versatility of the mold. When the spacing of the positioning channels 31 is set differently, it can provide a precise partitioned layout for wires of different specifications or functions to meet personalized processing needs, significantly improve the flexibility of product design and the adaptability of production processes, and effectively avoid the problems of wire crossing and mutual interference caused by traditional centralized layout. Furthermore, the spacing between multiple positioning channels 31 can be such that some positioning channels 31 have the same spacing and some positioning channels 31 have different spacing. For example, when the number of positioning channels 31 is set to 4 groups, the connection of the cross sections of each positioning channel 31 is in the form of a straight line, and the spacing between the first and second channels can be L1, the spacing between the third and fourth channels can be L1, and the spacing between the second channels can be L2, where L1 is less than L2.
[0040] In some embodiments, the glue inlet 22 is inclined toward the glue outlet section 21. The molten glue can flow more smoothly to the glue outlet channel 40 under pressure and evenly wrap the wire, avoiding the stagnation or uneven accumulation of molten glue at the glue inlet 22. This effectively improves the flow stability and wrapping uniformity of the molten glue, thereby enhancing the embedding effect of the wire and improving the quality stability of the finished product.
[0041] In some embodiments, a guide bevel 35 is provided on the fixed section 33 corresponding to the glue inlet 22. The cutting depth of the guide bevel 35 gradually increases along the direction approaching the reduced diameter section 34. This structural design can smoothly guide the molten glue as it enters the glue outlet channel 40, reducing resistance and turbulence when the molten glue enters. This allows the molten glue to be more evenly distributed at the wire outlet of the reduced diameter section 34, further enhancing the effect of the wire being uniformly wrapped by the molten glue, avoiding the problem of uneven thickness caused by molten glue accumulation, and improving the consistency of product quality.
[0042] In some embodiments, the connecting section 23 has several limiting notches 231 at its opening opposite to the dispensing section 21, and several positioning blocks 331 are provided on the fixing section 33. The positioning blocks 331 and the limiting notches 231 are engaged one-to-one. This structure ensures accurate and secure assembly between the positioning insert 30 and the dispensing nozzle 20, preventing rotation or axial displacement of the insert during processing. This ensures the positioning accuracy of the wire and the processing stability of the mold, improves the reliability of the overall structure and production efficiency, and reduces maintenance and adjustment costs.
[0043] In some implementations, the multiple positioning channels 31 can be set with the same color, different colors, or a combination of both. For example, by setting different color markings on the positioning insert 30 body for positioning channels 31 with different functions or specifications, the wire type or purpose corresponding to different channels can be clearly distinguished intuitively, facilitating operators to quickly and accurately install and replace wires, significantly improving assembly efficiency and reducing the probability of assembly errors. Meanwhile, positioning channels 31 with the same color are suitable for batch processing of wires of the same specification, helping to unify visual identification and simplify operation steps, effectively improving consistency and production efficiency during processing. Therefore, by differentiating colors, the entire processing process becomes more convenient and reliable, further enhancing the usability of the mold and production efficiency, ensuring product quality and market competitiveness.
[0044] In a preferred embodiment of this invention, the apertures of each positioning channel 31 can be set to be the same or different. When the apertures are the same, it is suitable for batch processing of wires with consistent specifications, effectively improving production efficiency. When the apertures are set differently, the size of the positioning holes can be optimized for wires of different diameters or specifications, accurately adapting to wires of different sizes. At the same time, different functional wire harnesses can be precisely configured, further improving the stable positioning effect of the wires and the consistency of finished product quality. This significantly improves the applicability and flexibility of the mold, effectively solving the problem of inaccurate wire positioning in the prior art, and enhancing product quality and market competitiveness.
[0045] A second embodiment of this application provides a multi-wire heating wire breathing circuit processing mold, including the multi-wire heating wire processing mold 10 as provided in the first embodiment of this application. This ensures that a plurality of wires can be arranged on the breathing circuit, and that each wire is uniformly wrapped with insulating adhesive.
[0046] In summary, this application provides a multi-wire heating wire processing mold and a multi-wire heating wire breathing circuit processing mold. The multi-wire heating wire processing mold is used to pre-embed wires in the breathing circuit. The multi-wire heating wire processing mold includes a dispensing nozzle and a positioning insert detachably connected to the dispensing nozzle. The dispensing nozzle has a dispensing section with a glue inlet. The positioning insert has multiple spaced positioning channels. A dispensing channel communicating with the glue inlet is provided between the positioning insert and the dispensing section. Multiple wires pass through the multiple positioning channels one by one, enter the dispensing channel at preset intervals, and exit the dispensing channel after being wrapped with molten glue. By incorporating a positioning insert with multiple spaced positioning channels within the hot nozzle, clear guidance and effective positioning of multiple wires are achieved before they enter the dispensing channel. Specifically, by threading each wire one-to-one into the multiple positioning channels, the wires maintain a stable, pre-set spacing distribution before entering the molten adhesive coating. This overcomes the problems of chaotic arrangement and uncontrollable spacing caused by concentrated wire entry in existing technologies. It ensures stable and orderly distribution of the wires within the spiral membrane, effectively preventing short circuits caused by contact between wires and avoiding wires detaching from the membrane and being exposed to external air. This significantly improves the electrical safety and mechanical performance of the breathing circuit product. Furthermore, the detachable structure of the positioning insert allows for flexible replacement according to wire specifications and functional requirements, facilitating effective zoning of different wires. This benefits subsequent processing and welding, thereby improving production efficiency and product consistency, reducing production costs, and enhancing overall product quality and market competitiveness.
