[0039] The heating pipeline provided by the embodiment of the present utility model is connected to the heating wire in the heating component through the connecting part of the fixing component, and then the fixing component abuts against the inner wall of the pipeline body through the first abutting part and the second abutting part, so as to fix the heating wire in the air flow channel of the pipeline body. Such a heating pipeline structure is relatively simple, which can reduce the production cost, and it is convenient to assemble the various components in the heating pipeline; there is a gap between the heating wire and the inner wall of the pipeline body, which can avoid the heating wire directly contacting the pipeline body during heating as much as possible and slow down the aging of the pipeline.

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 10 , the embodiment of the present utility model provides a heating pipeline, including:

[0042] A pipeline body 1, one end of the pipeline body 1 is provided with a first opening 11, and the other end is provided with a second opening 12. An air flow channel is formed between the first opening 11 and the second opening 12; in this way, air flow can enter from the first opening 11 or the second opening 12 of the pipeline body 1 and discharge from the second opening 12 or the first opening 11. In this application, it is exemplified that the air flow enters from the first opening 11 and discharges from the second opening 12.

[0043] A heating component 2, the heating component 2 includes a heating wire 21, the heating wire 21 is arranged in the air flow channel through a fixing component 3, and the heating wire 21 extends from the first opening 11 to the second opening 12; in this way, the heating wire 21 is fixed in the pipeline body 1. The heating wire 21 extends from the first opening 11 to the second opening 12, that is, it is placed along the path of the air flow channel. Such a structure can heat the air flow more effectively.

[0044] A fixing component 3, the fixing component 3 includes a connecting part 31, a first abutting part 32 and a second abutting part 33 opposite to the first abutting part 32. The heating wire 21 is connected to the fixing component 3 through the connecting part 31, and the fixing component 3 abuts against the inner wall of the pipeline body 1 through the first abutting part 32 and the second abutting part 33; the fixing component 3 can be assembled or integrally formed. The material of the fixing component 3 can be selected as a material with elastic deformation, and more specifically, it can be plastic. Selecting such a material to make the fixing component 3 is more convenient for installation, and the stability during use may be better.

[0045] It can be understood that the first abutting part 32 and the second abutting part 33 are connected, and the two are integrally U-shaped or V-shaped.

[0046] There is a gap between the heating wire 21 and the inner wall of the pipeline body 1.

[0047] Specifically, when producing and assembling the heating pipeline, the heating wire 21 can be first connected to the fixed component 3 through the connecting part 31, thereby realizing the connection between the heating component 2 and the fixed component 3. More specifically, one end or one head of the heating wire 21 is generally connected to the connecting part 31 of the fixed component 3, wherein the heating wire 21 and the fixed component 3 can be fixedly connected, movably connected, or other common connection methods in the field.

[0048] After the heating component 2 is connected to the fixing component 3, the first abutting portion 32 and the second abutting portion 33 on the fixing component 3 abut against the inner wall of the pipe body 1, so that the fixing component 3 is installed in the pipe body 1. In addition, the first abutting portion 32 and the second abutting portion 33 of the fixing component 3 are arranged opposite to each other, so that the first abutting portion 32 and the second abutting portion 33 respectively abut against different positions of the inner wall of the pipe body 1, which can improve stability.

[0049] It can be understood that there is a gap between the heating wire 21 and the inner wall of the pipe body 1, which can effectively reduce the damage caused by the heating wire 21 to the inner wall of the pipe body 1 and improve the durability of the heating pipe.

[0050] The heating pipeline provided in this embodiment is connected to the heating wire 21 in the heating component 2 through the connecting portion 31 of the fixing component 3, and then the fixing component 3 abuts against the inner wall of the pipeline body 1 through the first abutting portion 32 and the second abutting portion 33, thereby fixing the heating wire 21 in the air flow channel of the pipeline body 1. Such a heating pipeline structure is relatively simple, which can reduce the production cost, and the various components in the heating pipeline are easy to assemble; there is a gap between the heating wire 21 and the inner wall of the pipeline body 1, which can minimize the direct contact of the heating wire 21 with the pipeline body 1 during heating, thereby slowing down the aging of the pipeline.

[0051] Embodiment 2

[0052] See also Figure 4 , Figure 9 and Figure 10 In the embodiment of the utility model, the fixing assembly 3 also includes a third abutting portion 34, a fourth abutting portion 35 and a connecting rod 36. The third abutting portion 34 and the fourth abutting portion 35 are arranged opposite to each other, and the third abutting portion 34 and the fourth abutting portion 35 are connected to the first abutting portion 32 and the second abutting portion 33 through the connecting rod 36.

[0053] It can be understood that the fixing assembly 3 in this embodiment includes a third abutment portion 34, a fourth abutment portion 35 and a connecting rod 36 in addition to the first abutment portion 32 and the second abutment portion 33 in the first embodiment. The third abutment portion 34 and the fourth abutment portion 35 are arranged opposite to each other. The third abutment portion 34 and the fourth abutment portion 35 are connected to the first abutment portion 32 and the second abutment portion 33 through the connecting rod 36.

[0054] As Figure 4 shown, the planes where the first abutting portion 32 and the second abutting portion 33 are located are not the same plane as the planes where the third abutting portion 34 and the fourth abutting portion 35 are located. It can be understood that the positions where the first abutting portion 32 and the second abutting portion 33 abut are close to the second opening 12, and the positions where the third abutting portion 34 and the fourth abutting portion 35 abut are close to the first opening 11. In this way, by providing the third abutting portion 34 and the fourth abutting portion 35, the fixing effect of the fixing component 3 is enhanced, so that the heating wire 21 can be more stably arranged in the pipeline body 1.

[0055] Of course, if it is necessary to further increase the fixing effect of the fixing component 3, more abutting portions can be considered to be added to the fixing component 3. The technical solution of adopting four abutting portions in this embodiment is a better choice after comprehensively considering the fixing effect, the convenience of production and assembly, and cost factors.

[0056] Embodiment Three

[0057] Please refer to Figure 4 、 Figure 9 and Figure 10 . In the embodiment of the present utility model, the fixing component 3 further includes a reinforcing member 37, and the reinforcing member 37 is arranged between the third abutting portion 34 and the connecting rod 36 or / and between the fourth abutting portion 35 and the connecting rod 36.

[0058] The main function of the reinforcing member 37 is to increase the strength and stability of the fixing component 3 or more specifically, the abutting portions in the fixing component 3, and prevent the fixing component 3, especially the abutting portions, from being deformed too much during assembly or use and resulting in fracture. The design of the reinforcing member 37 can be selected according to different requirements. For example, it can be selected according to factors such as materials, shapes, and sizes, and is not limited to the design of such cross bars in this embodiment.

[0059] Embodiment Four

[0060] Please refer to Figures 4 to 7 and Figure 9 . In the embodiment of the present utility model, a first engaging portion 38 is provided between the first abutting portion 32 and the connecting rod 36 in the fixing component 3, and a second engaging portion 39 is provided between the second abutting portion 33 and the connecting rod 36.

[0061] One of the purposes of providing the engaging portions on the fixing component 3 is to facilitate installation.

[0062] Specifically, during the production and assembly process, after connecting the fixing component 3 and the heating component 2, at this time, an assembly part 4 is used. The assembly part 4 is passed through the air flow channel, and the hook head 41 on the assembly part 4 hooks the first hooking part 38 or / and the second hooking part 39. Then, the assembly part 4 is pulled to drive the fixing component 3 into the pipeline body 1. After pulling to the desired position, the hook head 41 is released, and the assembly part 4 is taken out, thus completing the assembly.

[0063] It can be understood that in this embodiment, the first hooking part 38 and the second hooking part 39 are provided. In addition to being able to hook any one of the hooking parts to achieve assembly, it can also be to hook the first hooking part 38 and the second hooking part 39 simultaneously. In this way, the possibility of damage to the fixing component 3 during the assembly process can be reduced. Additionally, with two hooking parts, the convenience of assembly is also improved.

[0064] The assembly part 4 is mainly used in the production and assembly process and does not belong to a part of the heating pipeline of the present utility model. The assembly part 4 itself does not directly affect the technical solution of the heating pipeline of this application.

[0065] In addition to being in the form of a hook similar to that mentioned in this embodiment, the assembly part 4 can at least also be in the form of a rope.

[0066] Embodiment Five

[0067] Please refer to Figure 4 、 Figure 7 、 Figure 9 and Figure 10 In the embodiment of the present utility model, the connecting part 31 in the fixing component 3 includes a third opening 311, and a protrusion 312 is provided in the third opening 311.

[0068] It can be understood that the connecting part 31 is the main component involved in the connection between the fixing component 3 and the heating component 2. A third opening 311 is provided in the connecting part 31, which is mainly applicable to the scenario where the fixing component 3 and the heating component 2 need to be assembled.

[0069] Specifically, one end of the heating wire 21 in the heating component 2 enters the connecting piece from the third opening 311, and then is movably connected to the fixing component 3 in a clamping, buckling or similar manner. Then, protrusions 312 are provided on one side or both sides of the third opening 311, so as to reduce the occurrence of shaking or other factors during use, resulting in the heating wire 21 detaching from the fixing component 3.

[0070] Embodiment Six

[0071] Please refer to Figure 1 、 Figure 9 and Figure 10, in the embodiment of the present utility model, the pipeline body 1 is a corrugated pipe. Grooves 13 are arranged at intervals on the inner wall of the pipeline body 1. The shapes, sizes or / and of the first abutting portion 32 and the second abutting portion 33 are adapted to the shapes and sizes of the grooves 13. Additionally, the shapes, sizes or / and of the third abutting portion 34 and the fourth abutting portion 35 are also adapted to the shapes and sizes of the grooves 13.

[0072] It can be understood that the pipeline body 1 is a corrugated pipe. Generally, a corrugated pipe can play a role in increasing strength and improving toughness, enabling the pipeline to remain stable when subjected to certain pressures or bends. Generally, annular grooves 13 are arranged on the inner side of the pipe wall of the corrugated pipe. The abutting portions of the fixing component 3 are set to be shaped like the grooves 13 of the corrugated pipe. Relying on the elastic deformation of the plastic, the abutting portions can be firmly and unidirectionally clamped into the grooves 13 of the corrugated pipe. The corrugated pipe in this embodiment can be other types of corrugated pipes in addition to the parallel corrugated pipes with parallel corrugations.

[0073] Embodiment Seven

[0074] Please refer to Figure 1 and Figure 8 , in the embodiment of the present utility model, the connecting portion 31 is detachably connected to one end of the heating wire 21.

[0075] It can be understood that the detachable connection between the connecting portion 31 and one end of the heating wire 21 means that the connecting portion 31 and the heating wire 21 can be disassembled and assembled repeatedly in a certain way. This design is beneficial to the replacement and maintenance of the heating wire 21.

[0076] During actual use, the heating wire 21 may be worn or malfunction due to long-term use and needs to be replaced regularly. Through the detachable connection design, the connecting portion 31 can be conveniently removed, so that the heating wire 21 can be taken out of the pipeline for replacement or repair.

[0077] This design not only improves the service life and reliability of the heating pipeline, but also reduces the maintenance cost and operation difficulty.

[0078] Embodiment Eight

[0079] Please refer to Figure 4 , Figure 7 , Figure 9 and Figure 10 , in the embodiment of the present utility model, the heating component 2 further includes an interface 22, and the interface 22 is hermetically connected to the first opening 11.

[0080] Specifically, one end of the heating component 2 is the heating wire 21, and the other end is the interface 22.

[0081] The interface 22 may be a plug or a connector for connecting with other equipment or pipelines. It is understandable that the interface 22 can prevent gas leakage by being sealed with the first opening 11 .

[0082] More specifically, the interface 22 may be sealed and connected to the first opening 11 by glue dispensing or other connection methods that can achieve sealing.

[0083] The sealed connection between the interface 22 and the first opening 11 helps to achieve a reliable connection and prevent potential leakage.

[0084] Embodiment 9

[0085] See also Figure 2 , Figure 3 , Figure 9 as well as Figure 10 In the embodiment of the utility model, the heating wire 21 of the heating component 2 is a spiral heating wire.

[0086] The spiral heating wire inside the pipe increases the area of ​​direct contact between the heating wire 21 and the gas in the airflow channel, transferring more heat to the gas through heat conduction. The spiral heating wire can improve heating efficiency and heating speed

[0087] Embodiment 10

[0088] See also Figures 1 to 10 , the utility model embodiment also provides a ventilator, including the heating pipeline in the above embodiment. In this embodiment, a heating pipeline is installed on the ventilator, and the heating pipeline is connected to the heating wire in the heating component through the connecting part of the fixing component, and then the fixing component abuts against the inner wall of the pipeline body through the first abutting part and the second abutting part, thereby fixing the heating wire in the air flow channel of the pipeline body. Such a heating pipeline structure is relatively simple, which can reduce the production cost, and the various components in the heating pipeline are easy to assemble; there is a gap between the heating wire and the inner wall of the pipeline body, which can avoid the heating wire directly contacting the pipeline body during heating as much as possible, and slow down the aging of the pipeline. Thereby, it is better to let the patient breathe mild fresh gas.

[0089] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.
