Description

Technical Field

[0001] The utility model relates to the technical field of air breathing apparatus, in particular to a positive pressure fire fighting air breathing apparatus which reduces the use burden. Background Art

[0002] Positive pressure fire fighting air respirator is a kind of equipment used for firefighters and other workers to provide respiratory protection in smoke, toxic gas or oxygen-poor environment. Its working principle is to provide compressed air through high-pressure gas cylinders to keep the inside of the respirator in a positive pressure state to prevent the invasion of harmful gases. The respirator usually consists of a mask, an air supply system, a backpack gas cylinder and a breathing valve. When the user inhales, the respirator will send fresh air into the mask to keep breathing comfortable and safe. Positive pressure fire fighting air respirator is widely used in emergency situations such as fire rescue and chemical leak treatment to protect users from harmful gases and ensure that they can complete the task safely.

[0003] Current positive pressure firefighting air breathing apparatuses play a vital role in the work of firefighters, but their heavy weight has become a challenge. Usually, these breathing apparatuses are heavy due to internal compressed gas cylinders and other equipment, and the fixed belt on the back requires firefighters to carry this weight for a long time. This not only increases the weight of firefighters, but may also affect their flexibility and speed of movement. Over time, this weight will gradually cause firefighters to become tired, reducing their work efficiency and safety. Especially during long firefighting tasks, this fatigue may intensify, affecting firefighters' work performance and ability to respond to emergencies. Utility Model Content

[0014] Reduce equipment weight: By designing the bottom plate and back plate, and using lightweight materials and structures, this fire breathing apparatus may be lighter than traditional designs, reducing the burden on users. The lightweight design helps firefighters wear it for a long time without feeling tired.

[0015] Good fixation: The back panel adopts an arc-shaped design, which, together with the shoulder strap, fixing belt and other structures, can better fit the user's body curve, ensuring that the respirator is firmly fixed during use and not easy to shake. At the same time, the design of the limit card and limit plate can also ensure the correct position of the respirator and enhance fixation.

[0016] Reduce the burden of use: The design of components such as the back panel, straps and waist belt takes into account ergonomics and comfort, reducing pressure and friction on the user's body, thereby reducing the burden on the user. In addition, the breathable pads and multi-angle protective pads on the back panel can also provide additional comfort and protection.

[0017] Convenient for long-term work: All these designs and advantages together ensure the applicability and comfort of this fire breathing apparatus, allowing firefighters to wear it for a long time and perform efficient work. The breathability and heat dissipation design can effectively reduce heat accumulation and maintain the user's comfort and tolerance. BRIEF DESCRIPTION OF THE DRAWINGS
