Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment technology, and more specifically, it relates to a portable high-altitude oxygen generation device. Background Technology

[0002] High altitudes, with their low air pressure and thin oxygen, make breathing difficult, especially during high-intensity work and rescue operations. Workers typically need to be equipped with oxygen generators to maintain an oxygen supply.

[0003] Currently, the most common oxygen generating devices on the market are high-pressure gas cylinder oxygen supply type and chemical agent oxygen supply type. Gas cylinder type supplies oxygen by mixing pre-filled high-pressure pure oxygen cylinders with outside air. Its gas volume is limited, and attention must be paid to operational safety when transporting and using high-pressure gas cylinders. Chemical agent type produces oxygen through chemical reaction. Similarly, attention must be paid to operational safety, and chemical agents are relatively expensive. In other words, current oxygen generating devices have the disadvantages of high cost and high operational requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-cost, easy-to-use and portable high-altitude oxygen generation device.

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

[0006] A portable high-altitude oxygen generator includes a backpack containing a compression intake assembly. The output of the compression intake assembly is connected to a one-way valve, and the output of the one-way valve is connected to a high-pressure gas cylinder. A pressure gauge is installed inside the high-pressure gas cylinder. The compression intake assembly is activated or deactivated based on the reading of the pressure gauge. A constant-pressure valve is connected to the opening of the high-pressure gas cylinder, and the output of the constant-pressure valve is connected to a constant-pressure gas cylinder. A face mask is connected to the opening of the constant-pressure gas cylinder. An on / off valve is installed on the mask's air hose. A storage assembly is located on the outside of the backpack, through which the mask's air hose is stored.

[0007] The present invention is further configured such that: the compressed air intake assembly includes an air pump and a battery, the battery drives the air pump, the output end of the air pump is connected to a one-way valve, and the air intake pipe of the air pump passes through the backpack.

[0008] The present invention is further configured such that: a support frame is provided inside the opening of the air intake pipe, a filter screen is provided on the support frame, the inner wall of the opening of the air intake pipe is provided with a threaded opening, a pressure cap is threaded onto the threaded opening, the pressure cap is a hollow structure, and the pressure cap presses on the filter screen.

[0009] The present invention is further configured such that: the constant pressure valve includes a valve body, the valve body is a cylindrical structure, an air inlet and an air outlet are radially oppositely opened on the cylindrical wall of the valve body, the air inlet is connected to a high-pressure gas cylinder, the air outlet is connected to a constant pressure gas cylinder, a cap is sealed to the open end of the valve body, a sealing membrane is provided between the cap and the valve body, the sealing membrane can move between the cap and the valve body, a connecting rod is connected to the sealing membrane, a valve core is connected to the end of the connecting rod away from the sealing membrane, and an air hole is radially opened through the valve core, the air hole can connect the air inlet and the air outlet.

[0010] The present invention is further configured such that: a connecting pipe is connected to the cover, the other end of the connecting pipe is connected to the air outlet, a power chamber is formed between the cover and the sealing membrane, the valve core is slidably connected to the inner wall of the valve body, the valve core is covered on the air inlet and the air outlet, the valve body, the sealing membrane and the valve core together form an atmospheric pressure chamber, a balance air port is connected to the atmospheric pressure chamber, the balance air port is connected to the outside atmosphere, a sliding frame is provided in the valve body, and the connecting rod slides axially on the sliding frame.

[0011] The present invention is further configured such that: the storage component includes a storage box, the storage box is fixed to the outside of the backpack, the storage box has an opening at the top, the storage box has a sliding groove on the side, a pressure rod is slidably connected in the sliding groove, and the mask air tube extends into the storage box from the top, passes under the pressure rod, and then extends out from the top of the storage box.

[0012] The advantages of this utility model are:

[0013] 1. The low-pressure air is compressed into the high-pressure cylinder through the air compression intake component, and then delivered to the constant pressure cylinder through the constant pressure valve for buffering before being supplied to the user for breathing. By increasing the inhalation pressure, the user's breathing efficiency is ensured. The process only consumes the power in the battery and there are no other losses, thus reducing the cost of use.

[0014] 2. A storage component is provided on the outside of the backpack. The storage box is slidably connected by a pressure rod. The mask air tube passes through the storage box and is pressed down by the pressure rod. The pressure rod has a limited weight, so it does not compress the soft mask air tube and change its flow area. At the same time, it can apply a certain pressure to the mask air tube, causing it to be moved down. This allows the mask air tube of any length beyond what is needed to be stored in the storage box, making it convenient to use and carry. Attached Figure Description
