[0002] With the widespread application of smart wearable protective devices, especially in scenarios such as fall protection airbag suits for the elderly and protective equipment for special workers, rapid inflation systems integrating small high-pressure gas cylinders have become core safety components. However, existing gas cylinder structures generally suffer from problems such as inconvenient replacement, poor sealing performance, high starting noise, and scattered components. Especially in high-frequency usage scenarios, the high sound pressure generated during gas release may also cause secondary disturbance to users. Utility Model Content

[0003] The purpose of this invention is to provide an inflatable component for protective clothing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an inflatable component for protective clothing, comprising a bottle body and a trigger movably mounted on the bottle body; the bottle body has a diaphragm inside, and the trigger includes a piercing needle for piercing the diaphragm; after the bottle body and the trigger are connected, a cavity is formed between the bottle body and the trigger, and the high-pressure gas inside the bottle body is released into the protective clothing through an air hole provided on the cavity.

[0005] As a preferred technical solution of this utility model: the trigger includes a connecting part, and the connecting part is provided with an annular groove, which is connected to the outside through a groove; wherein, the bottle body enters the annular groove along the groove through a protrusion, and the bottle body is rotated to achieve the assembly of the bottle body and the trigger.

[0006] As a preferred technical solution of this utility model: the end of the connecting part away from the bottle body is connected to a bracket, and the bracket is provided with an electromagnetic chuck for fixing the piercing needle.

[0007] As a preferred embodiment of this utility model, a spring is also provided between the piercing needle and the facing surfaces of the electromagnetic chuck.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0020] Please see Figure 1-5 This utility model provides an embodiment of an inflatable component for protective clothing, comprising a bottle body 1 and a trigger 3 movably mounted on the bottle body 1; the bottle body 1 has a diaphragm 6 inside, and the trigger 3 includes a piercing needle 32 for piercing the diaphragm 6; after the bottle body 1 and the trigger 3 are connected, a cavity 7 is formed between the bottle body 1 and the trigger 3, and the high-pressure gas inside the bottle body 1 is released into the protective clothing through the air hole 33 provided on the cavity 7.

[0021] In summary, since the bottle body 1 and the trigger 3 are movably connected, the assembly of the bottle body 1 and the trigger 3 is simple and convenient, so that the bottle body can be quickly replaced after the trigger 3 is fixed on the protective clothing. In particular, since the bottle body 1 and the trigger 3 form a cavity 7 after assembly, when the diaphragm 6 is punctured and high-pressure gas enters the cavity 7, the cavity 7 slows down the gas flow rate, thereby reducing the noise generated when the airflow flows out.

[0022] To address the issue of loosening and leakage caused by tightening in traditional threaded connections, the trigger element 3 includes a connecting portion 30 with an annular groove 34. This annular groove 34 connects to the outside via a slot 35. The bottle body 1, through a protrusion 2, enters the annular groove 34 along the slot 35, and is assembled with the trigger element 3 by rotating the bottle body 1. Therefore, once the protrusion 2 enters the annular groove 34, and then the protrusion 2 is offset from the slot 35, assembly of the bottle body 1 and the trigger element 3 is achieved. This simplifies the assembly process and avoids the problem of weak connections that occur with threaded connections. Especially in high-frequency applications, this improves installation efficiency while reducing the likelihood of loose connections. Furthermore, a plug-in mechanical connection can be used to achieve quick assembly and disassembly of the bottle body 1.

[0023] To prevent the puncture needle 32 from puncturing the membrane 6 due to accidental contact or other factors, the end of the connecting part 30 away from the bottle body 1 is connected to the bracket 38. The bracket 38 is equipped with an electromagnetic chuck 36 for fixing the puncture needle 32. Therefore, under normal conditions, the puncture needle 32 can be attracted to the electromagnetic chuck 36. The electromagnetic chuck 36 is commercially available; any chuck that can hold the puncture needle 32 and prevent abnormal triggering of the device is acceptable.

[0024] When normal use is required, in order to increase the speed of piercing the membrane 6, a spring 31 is provided between the opposing surfaces of the piercing needle 32 and the electromagnetic chuck 36. Therefore, when the magnetic force of the electromagnetic chuck 36 disappears, the elastic force of the spring 31 is used to make the piercing needle 32 pierce the membrane 6. When the bottle body 1 is replaced, the piercing needle 32 can be manually pushed to connect with the electromagnetic chuck 36 to make the piercing needle 32 return to the initial state so that the piercing needle 32 can be fired again.

[0025] To ensure the piercing needle 32 can move in a directional manner and to guarantee its stable, reliable, and rapid piercing of the membrane 6, the bottle body 1 is also provided with a support portion 5. The support portion 5 contains a groove 8 for guiding the piercing needle 32 in a directional manner. Simultaneously, when the membrane 6 is pierced, the high-pressure gas pushes the piercing needle 32 to separate from the membrane 6. At this time, a pressure-reducing chamber is formed inside the groove 8, further reducing the noise generated during gas release. Additionally, the circumferential surface of the support portion 5 is provided with multiple circular holes 4 and multiple air holes 33, allowing airflow to pass through these holes and vents for rapid exhaust.

[0026] Since the support portion 5 abuts against the inner wall of the bracket 38 after the bottle body 1 is connected to the trigger 3, and the bracket 38 is welded to the connecting portion 30, the end of the connecting portion 30 away from the bottle body 1 is sealed. Therefore, the connection between the bottle body 1 and the trigger 3 is stable and reliable, and the connection between the bracket 38 and the connecting portion 30 is also stable and reliable, while ensuring the sealing of the cavity 7.

[0027] In addition, since the bracket 38 is connected to the fixed member 37, and the bracket 38 is fixed to the air nozzle connector of the protective clothing through the fixed member 37, specifically, the fixed member 37 and the bracket 38 are connected by a threaded engagement, and the material of the fixed member 37 is preferably rubber. Therefore, while fixing the trigger member 3, the fixed member 37 can also be used to seal the connection between the trigger member 3 and the protective clothing.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
