[0054] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0055] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] Please see Figure 1 and Figure 2 This utility model provides an air nozzle assembly 100, including an air nozzle 10 and a structural part 20. The air nozzle 10 is used to communicate with an inflation device 1000. The structural part 20 is adapted to the air nozzle 10 to reduce the heat transfer of the air nozzle 10 to the outside. The air nozzle 10 and the structural part 20 are separately provided.

[0057] The air nozzle assembly 100 of the above embodiment, due to the air nozzle 10 of the air nozzle assembly 100 being adapted with the structure part 20, the structure part 20 can reduce the heat of the air nozzle 10 from being transferred outward to other structural parts (such as the shell 200 of the inflator 1000 or other components, etc.) of the inflator 1000, reduce the heat transfer at the air nozzle 10 to other structural parts, cause the other structural parts to be greatly heated to cause the probability of the other structural parts being damaged, be beneficial to prolong the service life of the other structural parts, ensure that the other structural parts can work reliably and stably, and provide a guarantee for the inflator 1000 including the air nozzle assembly 100 to have good performance. In addition, if the air nozzle 10 and the structure part 20 are integrally formed by insert injection molding process, the structure of the mold will be complicated due to the need to place the insert in the mold during the forming process, prolong the injection molding cycle, increase the manufacturing cost, and increase the processing difficulty. If the insert injection molding produces defective products due to poor injection, poor position, etc., the air nozzle assembly 100 will be scrapped, which is costly. The air nozzle 10 and the structure part 20 of the embodiment are separately arranged, that is, the air nozzle 10 and the structure part 20 are two independent components before assembly. The air nozzle 10 and the structure part 20 are separately processed and formed, and then the structure part 20 is adapted with the air nozzle 10 to form an assembly. The mold for processing the structure part 20 is simple, the cycle for processing the structure part 20 is short, and the mold cost for processing the assembly can be reduced to a certain extent, thereby reducing the manufacturing cost and processing difficulty of the air nozzle assembly 100. The air nozzle assembly 100 of the embodiment has reasonable structure design and strong practicability, and provides a guarantee for the inflator 1000 including the air nozzle assembly 100 to have good performance.

[0058] Exemplarily, the structure part 20 is sleeved outside the air nozzle 10, so that the structure part 20 can play a certain heat insulation role and reduce the probability of the heat of the air nozzle 10 being transferred outward to other structural parts of the inflator 1000. The structure part 20 can be in contact with the air nozzle 10 or not.

[0059] Exemplarily, the structure part 20 is made of a material with low thermal conductivity, such as plastic, rubber or other materials with low thermal conductivity.

[0060] Please refer to Figure 2 and Figure 3In some embodiments, the structure part 20 comprises a first structure member 21 and a second structure member 22, the second structure member 22 is connected with the first structure member 21 so that the structure part 20 is sleeved outside the gas nozzle 10 or the structure part 20 is built-in in the gas nozzle 10, thereby reducing the heat transfer of the gas nozzle 10 to the outside; the gas nozzle 10, the first structure member 21 and the second structure member 22 are separately arranged. The structure part 20 comprises the first structure member 21 and the second structure member 22 which are separately arranged, so that the assembly of the gas nozzle 10 and the structure part 20 is easier, more convenient and faster. Exemplarily, the structure part 20 is sleeved outside the gas nozzle 10, so as to balance the convenience of the connection between the structure part 20 and the gas nozzle 10 and the air tightness of the gas nozzle 10, and effectively reduce the heat transfer of the gas nozzle 10 to the outside.

[0061] Referring to Figure 2 In some embodiments, the gas nozzle 10 comprises a first section 11, a second section 12 and a protruding structure 13, the second section 12 and the first section 11 are sequentially connected along the gas conveying direction, and the protruding structure 13 is arranged at the connection between the first section 11 and the second section 12. The first structure member 21 and the second structure member 22 cover at least part of the protruding structure 13, and at least one of the first structure member 21 and the second structure member 22 covers the first section 11. The arrangement of the protruding structure 13 is conducive to the rapid positioning of the gas nozzle 10 and the structure part 20, and facilitates the rapid assembly of the gas nozzle 10 and the structure part 20.

[0062] Referring to Figures 2 to 5 In some embodiments, the gas nozzle 10 comprises a protruding structure 13, the first structure member 21 comprises a first slotted part 211, the second structure member 22 comprises a second slotted part 221, and the first slotted part 211 and the second slotted part 221 are arranged along the circumference of the gas nozzle 10 to cover at least part of the protruding structure 13. In this way, during the assembly of the gas nozzle assembly 100, the protruding structure 13 of the gas nozzle 10 can be matched with at least one of the first slotted part 211 and the second slotted part 221 to quickly and accurately achieve positioning, such as the positioning of the gas nozzle 10 and the first structure member 21 by matching the protruding structure 13 with the first slotted part 211, or the positioning of the gas nozzle 10 and the second structure member 22 by matching the protruding structure 13 with the second slotted part 221, thereby facilitating and quickly achieving the assembly of the gas nozzle 10, the first structure member 21 and the second structure member 22. Exemplarily, the protruding structure 13 comprises a circumferential side wall 131 located at the outermost side of the protruding structure 13, and the first slotted part 211 and the second slotted part 221 can cover the entire circumferential side wall 131 of the protruding structure 13. Exemplarily, the first slotted part 211 and the second slotted part 221 can cover part of the circumferential side wall 131, and another part of the circumferential side wall 131 is not covered by the first slotted part 211 and the second slotted part 221.

[0063] Referring to Figure 4 andFigure 5 In some embodiments, the second slotted portion 221 and / or the first slotted portion 211 has two spaced and opposite slotted side walls 2211 capable of limiting the position of the gas nozzle 10 along the conveying direction of the gas, and the slotted bottom wall of the first slotted portion 211 and the slotted bottom wall of the second slotted portion 221 cover at least part of the side wall of the protruding structure 13, i.e. the slotted bottom wall of the first slotted portion 211 and the slotted bottom wall of the second slotted portion 221 cover at least part of the circumferential side wall 131. In this way, after the gas nozzle 10, the first structural member 21 and the second structural member 22 are assembled, the two slotted side walls 2211 can limit the position of the gas nozzle 10 along the axial direction of the gas nozzle 10, preventing the relative movement of the gas nozzle 10 and the structural portion 20 in the conveying direction of the gas, and facilitating the reliable connection of the gas nozzle 10 and the structural portion 20. For example, the first slotted portion 211 has two spaced and opposite slotted side walls 2211. For example, the second slotted portion 221 has two spaced and opposite slotted side walls 2211. For example, one of the two slotted side walls 2211 can be provided on the first slotted portion 211, and the other one of the two slotted side walls 2211 can be provided on the second slotted portion 221.

[0064] The shape of the protruding structure 13 can be designed according to actual needs, such as the shape of the circumferential side wall 131 of the protruding structure 13 being a circular ring or a non-circular ring. Please refer to Figure 2 In some embodiments, the shape of the protruding structure 13 includes a polygon, and the shape of the slotted bottom wall of the first slotted portion 211 and the shape of the slotted bottom wall of the second slotted portion 221 are adapted to the shape of the protruding structure 13. The shape of the protruding structure 13 includes a polygon, which can prevent the relative rotation of the gas nozzle 10 and the structural portion 20 after assembly, and also facilitates material saving. In other embodiments, the shape of the protruding structure 13 can also be an elliptical shape or other non-circular ring shape. For example, the shape of the slotted bottom wall of the first slotted portion 211 and the shape of the slotted bottom wall of the second slotted portion 221 are adapted to the shape of the circumferential side wall 131 of the protruding structure 13.

[0065] In some embodiments, the first slotted portion 211 and the second slotted portion 221 cooperate to form a ring structure, and the cross-sectional dimension of the ring structure is greater than the cross-sectional dimension of other parts of the structural portion 20, i.e. the cross-sectional dimension of the ring structure is greater than the cross-sectional dimension of the parts of the structural portion 20 other than the ring structure, so that the first slotted portion 211 and the second slotted portion 221 can cooperate with the protruding structure 13, thereby achieving the positioning of the gas nozzle 10 and the first structural member 21, and achieving the positioning of the gas nozzle and the second structural member 22, facilitating the quick and convenient positioning and installation of the gas nozzle 10 and the structural portion 20.

[0066] Please refer to Figure 2 , Figure 4 andFigure 5 In some embodiments, the air nozzle 10 comprises the first section 11, the first structural member 21 further comprises a first open groove portion 212 connected with the first slotted portion 211, and the second structural member 22 further comprises a second open groove portion 222 connected with the second slotted portion 221. The first open groove portion 212 and the second open groove portion 222 are arranged along the circumference of the first section 11 to cover at least part of the first section 11, so as to increase the area of the structural portion 20 covering the air nozzle 10 and effectively reduce the probability of damage to other structural members of the inflating device 1000 caused by heat dissipation from the air nozzle 10.

[0067] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the air nozzle 10 comprises the first section 11, the first structural member 21 further comprises a ring-shaped portion 213 connected with the first slotted portion 211 or the first open groove portion 212 of the first structural member 21, and the ring-shaped portion 213 is arranged outside or inside the first section 11. For example, the ring-shaped portion 213 is arranged outside the first section 11, which can increase the area of the structural portion 20 covering the air nozzle 10 and effectively reduce the probability of damage to other structural members of the inflating device 1000 caused by heat dissipation from the air nozzle 10. In addition, the arrangement of the ring-shaped portion 213 can also limit the relative movement between the air nozzle 10 and the first structural member 21 to some extent, which is beneficial to improve the assembly reliability of the structural portion 20 and the air nozzle 10.

[0068] In some embodiments, the first structural member 21 and the second structural member 22 are detachably connected. In this way, the first structural member 21 and the second structural member 22 are easy and convenient to disassemble, and the structural portion 20 and the air nozzle 10 are easy and convenient to disassemble, which is beneficial to replace the first structural member 21, the second structural member 22 or the structural portion 20. When one or more of the first structural member 21, the second structural member 22 and the air nozzle 10 are damaged, only the damaged part needs to be replaced, without the need to replace the assembly formed by the structural portion 20 and the air nozzle 10, which is simple in structure, convenient in assembly and effective in reducing the cost.

[0069] For example, the detachable connection mode of the first structural member 21 and the second structural member 22 comprises at least one of the following: magnetic attraction connection, plug-in connection, screw locking connection, adhesive connection, threaded connection, etc.

[0070] Please refer to Figure 4 and Figure 5In some embodiments, the first structure 21 comprises a first connecting part 214, the second structure 22 comprises a second connecting part 223, one of the first connecting part 214 and the second connecting part 223 comprises a positioning slot, and the other comprises a positioning column which is adapted to the positioning slot. In this way, the first structure 21 and the second structure 22 are assembled conveniently, quickly and easily, and the structure 20 has a simple structure. For example, the first connecting part 214 comprises the positioning slot, and the second connecting part 223 comprises the positioning column which is adapted to the positioning slot. For another example, the first connecting part 214 comprises the positioning column, and the second connecting part 223 comprises the positioning slot which is adapted to the positioning column.

[0071] The number of the first connecting part 214 can be designed according to actual needs, such as one, two, three or more. The number of the first connecting part 214 comprises a plurality, and the shape of the second connecting part 223 is adapted to the shape of the first connecting part 214 to improve the positioning reliability and facilitate the reliable connection of the first structure 21 and the second structure 22. For example, the number of the first connecting part 214 is correspondingly arranged with the number of the second connecting part 223. The number of the first connecting part 214 can be the same as or different from the number of the second connecting part 223. For example, the number of the first connecting part 214 is one-to-one correspondingly arranged with the number of the second connecting part 223.

[0072] For example, the shapes of the first connecting parts 214 are different, such as the shapes of at least two of the first connecting parts 214 are different, so that the structure 20 can be compatible with multiple different models of the air nozzle 10, improve the compatibility of the structure 20, and expand the application range. For example, one of the plurality of first connecting parts 214 is a cylindrical column, and another of the plurality of first connecting parts 214 is a square column. For example, the shapes of the first connecting parts 214 can also be the same.
