It is typically used to deal with emergencies such as toxic gases, smoke, and lack of oxygen, such as fires, chemical leaks, or other hazardous environments.
[0003] Existing fully sealed self-rescue respirators generally only provide air purification and filtration protection for the wearer in fire scenarios. However, in fire scenes with dense smoke and low visibility, one-way protection is insufficient to ensure the escape of trapped personnel. Rescuers need to actively search for trapped individuals, which takes a long time and requires searching room by room. Therefore, the safety performance needs to be improved. Hence, there is a need for a fully sealed self-rescue respirator with a built-in audible warning function. Utility Model Content
[0004] The purpose of this invention is to solve the above-mentioned problems by proposing a fully sealed self-rescue respirator. This invention improves upon the existing fully sealed self-rescue respirators, which in fire scenarios generally only provide air purification and filtration protection for the wearer. However, in fire scenes with dense smoke and low visibility, the one-way protection is insufficient to ensure the escape of trapped personnel. Rescuers are required to actively search for trapped personnel, which takes a long time and requires searching room by room, thus compromising safety performance.
[0005] A fully sealed self-rescue respirator includes a fully sealed self-rescue respirator body, a position indicator component, a buckle adjustment component, and a rope adjustment component;
[0006] The location indicator component includes reflective strips, audible and visual alarm lights, and control buttons. Reflective strips are symmetrically sewn onto the outer side wall of the fully enclosed self-rescue respirator body located at the shoulder position. An audible and visual alarm light is fixedly installed on the cover of the fully enclosed self-rescue respirator body located at the top of the head.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In practical implementation: such as Figure 1-4 As shown, a fully sealed self-rescue respirator includes a fully sealed self-rescue respirator body 1, a position indicator component 2, a buckle adjustment component 3, and a rope adjustment component 4;
[0022] The location indicator component 2 includes a reflective strip 21, an audible and visual alarm light 22, and a control button 23. The reflective strip 21 is symmetrically sewn onto the outer side wall of the fully enclosed self-rescue respirator body 1 located at the shoulder position. The audible and visual alarm light 22 is fixedly installed on the cover of the fully enclosed self-rescue respirator body 1 located at the top of the head. The control button 23 for controlling the opening and closing of the audible and visual alarm light 22 is installed on the outer side wall of the fully enclosed self-rescue respirator body 1 located at the shoulder position.
[0023] The reflective strip 21 is designed to help rescuers locate the person in dense smoke by reflecting light through the reflective properties of the strip when using a high-powered flashlight. The control button 23 is used to control the activation and deactivation of the audible and visual alarm light 22. When the person being rescued is in a dense smoke environment, they can press the control button 23 to activate the audible and visual alarm light 22. Once activated, the alarm light 22 will automatically sound an alarm and illuminate the warning light, thus helping rescuers locate themselves through a combination of sound and light.
[0024] The buckle adjustment assembly 3 includes a button 31, a strap 32, and a fastening hole 33. The lower end of the cape of the fully enclosed self-rescue respirator body 1 is set as an open structure, and the two outer walls of the cape located at the opening are respectively sewn with a button 31 and a strap 32. The outer wall of the side of the strap 32 is equally spaced and has fastening holes 33 for passing through and installing with the button 31.
[0025] After the user puts on the fully enclosed self-rescue respirator body 1, the strap 32 can be tightened to a suitable length and the button 31 can be fastened into the corresponding hole 33. This design can effectively close the lower part of the cape of the fully enclosed self-rescue respirator body 1, and effectively reduce the amount of smoke entering the fully enclosed self-rescue respirator body 1 by reducing the contact area between the hem of the fully enclosed self-rescue respirator body 1 and the air.
[0026] The rope adjustment assembly 4 includes an elastic rope 41, a hollow column 42, an I-shaped column 43, and a limiting groove 44. The elastic rope 41 is threaded and installed inside the neck area of the fully enclosed self-rescue respirator body 1, with the end of the elastic rope 41 located outside the neck area of the fully enclosed self-rescue respirator body 1. The top outer wall of the hollow column 42 is designed as an open structure, and the I-shaped column 43 is slidably installed inside the hollow column 42. The elastic rope 41 is wound around the I-shaped column 43. On the outer side, four sets of limiting grooves 44 for threading elastic ropes 41 are provided through the outer wall of the side of the cavity column 42. The end of the elastic rope 41 is sleeved on the outer side of the shell of two adjacent sets of limiting grooves 44 of the cavity column 42. A contact spring 45 is connected and installed between the bottom outer wall of the I-shaped column 43 and the bottom inner wall of the cavity column 42. A positioning column 46 is fixedly installed on the bottom inner wall of the cavity column 42 at the center position. The positioning column 46 is located in the inner ring position of the contact spring 45.
[0027] After the user puts on the fully enclosed self-rescue respirator body 1, they can press down on the I-shaped column 43 directly. As the I-shaped column 43 is pressed down, it loses its resistance to the elastic rope 41. At this time, the contact spring 45 is compressed by the compression of the I-shaped column 43. Then, the elastic rope 41 can be pulled out or put back to the appropriate length. After adjustment, the I-shaped column 43 is released. At this time, the reaction force generated by the compression of the contact spring 45 will automatically push the I-shaped column 43 upward and reposition the elastic rope 41 in the middle of the housing between the limiting groove 44 and the cavity column 42. This allows for quick adjustment of the length of the elastic rope 41. The positioning column 46 here provides a limiting and auxiliary support for the contact spring 45, preventing it from being pressed down too hard and deformed excessively.
[0028] The fastening hole 33 is designed in the shape of a straight line; with this design, when the fastening button 31 is fastened into the fastening hole 33, it will change from the initial straight line shape to a circle, thereby better positioning the fastening button 31 inside the fastening hole 33.
[0029] The overall height of the positioning post 46 is lower than the height of the contact spring 45 when it is in the compressed state, and there is a certain gap between the positioning post 46 and the I-shaped post 43; this design ensures that the I-shaped post 43 will not be blocked by the positioning post 46 when it is pressed down, thus preventing it from moving down.
[0030] When using this utility model, after the user puts on the fully enclosed self-rescue respirator body 1, they can directly press down on the I-shaped column 43. As a result, the I-shaped column 43 loses its resistance to the elastic rope 41. At this time, the contact spring 45 is compressed by the compression of the I-shaped column 43. Then, the elastic rope 41 can be pulled out or put back to the appropriate length. After adjustment, the I-shaped column 43 is released. At this time, the reaction force generated by the compression of the contact spring 45 will automatically push the I-shaped column 43 upward and reposition the elastic rope 41 in the middle of the housing between the limiting groove 44 and the cavity column 42. Thus, the length adjustment of the elastic rope 41 can be quickly achieved. The positioning column 46 here plays a limiting and auxiliary support role for the contact spring 45, preventing it from being pressed down too hard and deformed excessively.
[0031] Then tighten the strap 32 to a suitable length and fasten the button 31 into the corresponding hole 33. This design can effectively close the lower end of the cape of the fully enclosed self-rescue respirator body 1, and effectively reduce the amount of smoke entering the fully enclosed self-rescue respirator body 1 by reducing the contact area between the hem of the fully enclosed self-rescue respirator body 1 and the air.
[0032] The reflective strip 21 is designed to help rescuers locate the person in dense smoke by reflecting light through the reflective properties of the strip when using a high-powered flashlight. The control button 23 is used to control the activation and deactivation of the audible and visual alarm light 22. When the person being rescued is in a dense smoke environment, they can press the control button 23 to activate the audible and visual alarm light 22. Once activated, the alarm light 22 will automatically sound an alarm and illuminate the warning light, thus helping rescuers locate themselves through a combination of sound and light.
[0033] The internal structure of the fully enclosed self-rescue respirator body 1 is described here. For the specific composition of the fully enclosed self-rescue respirator, please refer to the existing fully enclosed self-rescue respirators. As for how to wear it, please follow the existing operating instructions. It is a conventional operating technique and will not be described in detail here.
[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
