Description

Technical Field

[0001] The invention relates to the field of oxygen configuration, and in particular to a portable oxygen generator. Background Art

[0002] Oxygen is an indispensable element of life for the human body and the basis for human survival. It has been widely used in medical and health care and family health care. Oxygen inhalation is extremely beneficial to physical and mental health. With sufficient oxygen supply, our work efficiency and mental state will improve. However, in some special cases, the human body will be hypoxic, which will threaten health. However, at present, portable oxygen concentrators are relatively simple, most of which are powered by electricity, and are often large in size and weight, with a single oxygen supply method, which cannot meet the oxygen needs of different hypoxic groups. In the event of sudden natural disasters, emergencies or accidents, the wounded are concentrated, the space for use is small, and the power supply is insufficient, so that the oxygen concentrator cannot play its maximum role, seriously affecting the efficiency of treatment.

[0003] Therefore, it is necessary to design a small portable oxygen concentrator that does not require power supply to solve the above technical problems. Summary of the invention

[0004] In view of the deficiencies of the above-mentioned technology, the object of the present invention is to provide a handheld portable oxygen concentrator to solve the problems in the prior art that the oxygen concentrator is inconvenient to carry, the usage steps are not simple, and the oxygen production effect is not ideal in emergency situations.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A handheld portable oxygen concentrator includes a switch part on the left side of the device, a gear set part on the top of the device, a reaction chamber below the device and an air outlet pipe part on the right side of the device. The switch part is composed of a button, a rack and a spring from top to bottom. The gear set is composed of two gears of the same size, a "T"-shaped rod and a rectangular block filled with manganese dioxide. The end of the "T"-shaped rod is connected to the gear on the lower right side, and the left and right ends of the "T"-shaped rod are respectively connected to the rectangular block filled with manganese dioxide and the inside of the air outlet pipe. The contact surface between the "T"-shaped rod and the air outlet pipe is open rubber. The left end of the "T"-shaped rod that is in communication with the rectangular block is provided with a longitudinal protrusion. A compartment is provided in the reaction chamber, and the compartment is open on both sides. A heavy block is installed in the compartment, and the reaction chamber is in communication with the air outlet pipe.

[0007] The working principle of this technical solution is:

[0008] The rectangular block is connected to the reaction chamber, and the contact surfaces of the two are in contact. A weight block is set in the compartment in the reaction chamber to block the hydrogen peroxide. Therefore, when the device is tilted or used upside down, the weight block can ensure that the hydrogen peroxide will not leak and the device can be used normally. At the same time, because the right end of the "T"-shaped rod is connected to the exhaust pipe, when the device is not in use, the hydrogen peroxide will not leak out of the device.

[0009] It is further defined that when the switch part is in a pressed state, the gear is driven to rotate, so that the "T"-shaped rod connected to the gear moves, thereby controlling the lifting and lowering of the rectangular block and the closing of the air outlet pipe. The benefit is that when the switch part is in a pressed state, the device can be driven, avoiding the complication of operation and the inconvenience of use.

[0010] It is further defined that a partition is provided at the lower end of the rectangular block, manganese dioxide is contained in the partition, and the partition is surrounded by a filter screen with a hole diameter smaller than the diameter of manganese dioxide. The rectangular block is in communication with the reaction chamber, and an opening that fits the rectangular block is provided on the contact surface between the reaction chamber and the rectangular block, and when the switch portion is not pressed, a portion of the lower end of the rectangular block is already submerged in the reaction pool. The benefit is that when the device is not in use, the hydrogen peroxide in the reaction chamber will not leak, making it convenient to carry the device; when the device is in use, the rectangular block can accurately enter the reaction chamber, avoiding the problem of the rectangular block getting stuck and unable to enter the reaction chamber.

[0011] Further defined, the portable handheld oxygen concentrator is characterized in that holes are opened on the upper and lower sides of the compartment in the reaction chamber, and a smooth weight block is provided in the compartment to fit the interior of the compartment. The benefit is that even if the device is turned upside down, the weight block can still block the hydrogen peroxide, does not affect normal use, and avoids the problem of being unable to use due to direction.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the portable oxygen concentrator;

[0013] (1) Under the action of gravity, the weight block in the reaction chamber compartment will move to block the outflow of hydrogen peroxide, so that the device can be used normally at all angles. (2) Oxygen is produced by pressing the switch part, without the need for electricity, solar energy or other energy sources, so that the use restrictions of this device are less than those of previous oxygen production devices. (3) The internal parts of this device are fewer than those of previous oxygen production devices, which reduces the size of the device and makes it easier to carry and use.

[0021] A portable handheld oxygen concentrator includes a switch part on the left side of the device, a gear set part on the top of the device, a reaction chamber on the bottom of the device and an air outlet pipe part on the right side of the device. The switch part is composed of a button, a rack and a spring from top to bottom. The specific composition method can be a bonding or mortise and tenon structure. The rack fits with the gear, and the gear set is composed of two gears of the same size, a "T"-shaped rod and a rectangular block containing manganese dioxide. The gears are arranged in a manner of one on the upper left and one on the lower right. The end of the "T"-shaped rod is connected to the gear on the lower right, and the left and right ends of the "T"-shaped rod are respectively connected to the rectangular block containing manganese dioxide and the inside of the air outlet pipe. The contact surface between the "T"-shaped rod and the air outlet pipe can be composed of open rubber, plastic and other materials. After pressing the switch part, the rack will drive the gear and the "T"-shaped rod to move, thereby opening the air outlet pipe and starting the reaction process. The left end of the "T"-shaped rod that is connected to the rectangular block is provided with a longitudinal protrusion. The purpose is to prevent the rectangular block from sliding off. The reaction chamber stores hydrogen peroxide and is provided with a compartment, which has openings on both sides, and a weight block is installed in the compartment. Therefore, when the device is used at an angle, the weight block can block one side of the openings on both sides to prevent hydrogen peroxide from leaking. The reaction chamber is connected to the air outlet pipe.

[0022] The principle of oxygen production is to connect the switch part with the gear, and the gear can be controlled by the switch part. The "T"-shaped rod is connected to the air outlet pipe, and the contact surface is open rubber, which can improve the air tightness of the air outlet pipe under the premise of ensuring the normal use of the device. The left end of the "T"-shaped rod that is in communication with the rectangular block is provided with a longitudinal protrusion, so it can play a role in fixing the rectangular block. A compartment is provided in the reaction chamber, and the upper and lower sides of the compartment are open. The weight block inside blocks the hydrogen peroxide. Of course, when the device is tilted, the weight block blocks the hole on one side of the compartment under the action of gravity, blocks the hydrogen peroxide, and ensures that the oxygen produced by the reaction can be discharged into the air outlet pipe.
