Description

Technical Field

[0001] This utility model relates to the field of personal breathing device technology, and more specifically, it relates to a wearable oxygen generator for use at high altitudes. Background Technology

[0002] Wearable oxygen generators are typically shoulder bags worn on the back or waist, and are widely used in high-altitude activities, mine rescue, hazardous chemical accident handling, and fire rescue due to their portability.

[0003] Oxygen generators are typically heavy due to their high-pressure sealing and long-term battery life requirements. Currently, wearable devices on the market are usually secured directly with shoulder straps or waist belts. The weight of the device is directly applied to the user through these straps. During prolonged use, the straps exert significant pressure on the areas in contact with the user, which can easily cause fatigue or even blood stasis, resulting in poor usability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wearable oxygen generator for high-altitude use that is less tiring.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wearable oxygen generator for high-altitude use includes a gas canister with a flow regulating valve connected to it. The outlet of the flow regulating valve is connected to a breathing mask. A mounting frame is installed on the outside of the gas canister. A back panel is connected to the side of the mounting frame away from the gas canister. The back panel is curved to fit the user's back. The bottom end of the back panel extends to the user's waist, and the top end extends to the user's neck. Waist belts are connected to both sides of the bottom end of the back panel, and shoulder straps are connected to both sides of the mounting frame.

[0007] The present invention is further configured such that: the waist belt is trapezoidal, one long side of the waist belt is connected to the back panel, the upper end of one long side of the waist belt extends to the middle of the user's back, and the lower end of one long side of the waist belt is flush with the bottom end of the back panel.

[0008] The present invention is further configured such that: a lock is installed on one of the short sides of the trapezoidal waist belt, a restraint strap is provided on the waist belt, and buckles are connected to the restraint straps on both sides and the two back straps, and the buckles can be engaged with the lock.

[0009] The present invention is further configured such that both the restraint strap and the back strap are adjustable in length.

[0010] The present invention is further configured such that: the fixing frame includes an upper bracket and a lower bracket, the upper bracket is positioned at a position not lower than the user's shoulder, and the lower bracket is positioned at the same height as the waist belt.

[0011] The advantages of this utility model are:

[0012] 1. It features a curved back panel that conforms to the user's back, providing additional support and relieving back fatigue. The weight of the gas canister is also distributed along the panel surface when it is applied to the user, improving comfort.

[0013] 2. The gas canister is fixed to the back panel by a mounting bracket. The bottom of the back panel is fixed to the user's waist by a waist belt. The top of the mounting bracket is fixed to the waist belt by a shoulder strap. The shoulder strap fits the user's shoulders and chest. The connection between the lower support and the back panel can be regarded as a fulcrum. The upper support, which is not lower than the user's shoulders, can be regarded as the movable end and fixed by the shoulder strap. That is, the upper support is the force point, which increases the length of the lever arm, saves effort, and makes the user less tired. Attached Figure Description

[0021] Please see Figure 1-3The present invention provides the following technical solution:

[0022] A wearable oxygen generator for high-altitude use includes a gas tank 1, a flow regulating valve 2 connected to the gas tank 1, and a breathing mask 3 connected to the outlet of the flow regulating valve 2, forming the main body of the oxygen generator; a fixing frame 4 is installed on the outside of the gas tank 1, and a back plate 5 is connected to the side of the fixing frame 4 away from the gas tank 1. The bottom end of the back plate 5 extends to the user's waist, and the top end of the back plate 5 extends to the user's neck. Waist belts 6 are connected to both sides of the bottom end of the back plate 5, and shoulder straps 7 are connected to both sides of the fixing frame 4. The user carries the oxygen generator through the waist belts 6 and shoulder straps 7 for use.

[0023] The fixing frame 4 includes an upper bracket 41 and a lower bracket 42. The upper bracket 41 is set at a position no lower than the user's shoulder, and the lower bracket 42 is set at the same height as the waist belt 6. When in use, the gas canister 1 is fixed to the user's waist through the lower bracket 42 and the waist belt 6. The shoulder strap 7 pulls the upper end of the gas canister 1 and fixes it, so that the gas canister 1 is fixed to the user's body and will not fall off.

[0024] The connection point between the lower support 42 and the back panel 5 can be considered as a fulcrum, and the connection point between the upper support 41 and the shoulder strap 7 is the force-bearing point. Compared with the existing technology that uses shoulder lifting, this application has a longer lever arm, requires less effort, relieves pressure on the shoulders and back, and reduces user fatigue.

[0025] The back panel 5 is curved to fit the user's back. When it is tied to the user's back by the waist belt 6 and the back strap 7, it provides some auxiliary support to the back and can relieve the user's back fatigue. In addition, the back panel 5 has a large area, so the force exerted by the air tank 1 on the user is directly applied to the back panel 5 and the force is distributed along the surface of the back panel 5, which improves the user's comfort.

[0026] The waist belt 6 is trapezoidal, with one long side of the waist belt 6 connected to the back panel 5. The upper end of one long side of the waist belt 6 extends to the middle of the user's back, and the lower end of one long side of the waist belt 6 is flush with the bottom of the back panel 5. When the waist belt 6 is fixed, it is tightly wrapped around the user's waist. The waist belt 6 is wider on one side of the back, thus providing good support and reducing the burden on the waist.

[0027] One of the waist belts 6 has a lock head 8 installed on one of the short sides of the trapezoid. The waist belt 6 is equipped with a restraint strap 61. Buckles are connected to the restraint straps 61 on both sides and the two back straps 7. The buckles can be engaged with the lock head 8 to achieve fixation. The restraint straps 61 and the back straps 7 can be adjusted in length according to usage requirements.

[0028] Specifically, a curved back panel 5 is provided, which can fit against the user's back. The curved back panel 5 has a certain auxiliary support function, which can relieve the user's back fatigue. When the weight of the gas canister 1 is applied to the user through the back panel 5, it is distributed along the panel surface, which improves the comfort of use.

[0029] The gas canister 1 is fixed to the back panel 5 by the fixing bracket 4. The bottom end of the back panel 5 is fixed to the user's waist by the waist belt 6. The upper end of the fixing bracket 4 is fixed to the waist belt 6 by the back strap 7. The back strap 7 fits the user's shoulders and chest. The lower support 42 can be regarded as a fulcrum when it is connected to the back panel 5. The upper support 41 can be regarded as a movable end when it is not lower than the user's shoulders and is fixed by the back strap 7. That is, the upper support 41 is the force point, which increases the length of the lever arm, saves more effort, and makes it less tiring for the user.
