[0002] Small oxygen concentrators are very useful for families in high-altitude areas or with lung disease patients. However, current small oxygen concentrators have the following problems during use: First, the usage scenarios of small oxygen concentrators often change, so the location of the oxygen concentrator needs to be moved frequently. Therefore, the power cord and air supply pipe need to be unplugged for relocation. Current oxygen concentrators lack storage space, and the power cord and air supply pipe are easily lost after disassembly, affecting the normal use of the oxygen concentrator next time, and thus affecting the user experience. Second, the compressor of the oxygen concentrator vibrates and makes noise during use, which also affects the user experience. Utility Model Content

[0059] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0060] like Figures 1 to 10 As shown, an oxygen concentrator that is easy to store includes:

[0061] The housing 1 has a roller at its lower end, a storage groove 103 on its upper surface, and a storage groove 106 on its side wall.

[0062] The oxygen generation unit is configured to produce a gas with a high oxygen concentration by adsorbing nitrogen.

[0063] Cover plate 2, which is detachably connected to housing 1, is used to close the upper opening of the storage slot;

[0064] Storage box 3 is installed inside storage slot 2 106, and the lower end of storage box 3 is hinged to housing 1.

[0065] The side wall of the housing 1 has a hand slot 105, which facilitates the movement of the oxygen generator; there are four rollers, with two universal wheels 102 installed at one end of the lower end face of the housing 1 and two ordinary rollers 101 installed at the other end. The universal wheels 102 and ordinary rollers 101 facilitate the movement of the oxygen generator.

[0066] A first vertical plate 20201 is fixedly mounted on both sides of the lower end of the cover plate 2, and a horizontal plate 202 is fixedly mounted on the first vertical plate 20201. A second vertical plate 10401 is fixedly mounted on both sides of the housing 1 on the receiving groove 103. A limiting plate 104 is fixedly mounted on the upper end of the second vertical plate 10401. The distance between the limiting plate 104 and the housing 1 matches the thickness of the horizontal plate 202. The horizontal plate 202 is installed between the limiting plate 104 and the housing 1. A limiting pin 203 is fixedly mounted on one end of the cover plate 2. A limiting boss 20301 is fixedly mounted on the upper end surface of the limiting pin 203 away from the cover plate 2. A limiting hole 107 corresponding to the limiting pin 203 is opened on the housing 1. The inner side of the limiting hole 107... The upper end face of the limit pin 203 corresponds to the upper end face of the limit pin 203. The limit pin 203 is a plastic structural component. When the limit pin 203 is inserted into the limit hole 107, one end of the limit boss 20301 of the limit pin 203 moves downward. After being inserted into the limit hole 107, the limit pin 203 is reset. The limit boss 20301 plays a limiting role to prevent the cover plate 2 from moving. When it is necessary to open the cover plate 2, press the cover plate 2 at one end of the limit pin 203. The limit pin 203 moves downward as a whole. Now the boss is released from the limit, and the cover plate 2 can be pulled out. The operation process is convenient. The storage slot 103 can hold the power cord or spare gas supply pipe, which improves the storage function of the oxygen concentrator.

[0067] An anti-slip protrusion 201 is fixed on the upper surface of the cover plate 2, which facilitates the movement of the cover plate 2; the edge of the limiting plate 104 away from the limiting hole 107 and near the first vertical plate 20201 is chamfered, which facilitates the alignment of the first vertical plate 20201 with the limiting plate 104, thereby allowing the horizontal plate 202 to be inserted between the limiting plate 104 and the housing 1.

[0068] A hinge shaft 301 is fixedly provided at the lower end of the storage box 3, and the storage box 3 is hinged to the housing 1 through the hinge shaft 301. The side wall of the storage box 3 away from the second storage slot 106 matches the opening of the second storage slot 106, and the side wall of the storage box 3 away from the second storage slot 106 is used to close the opening of the second storage slot 106. A strong magnetic block 302 is fixedly provided on the inner side of the side wall of the storage box 3 away from the second storage slot 106, and a strong magnetic block 2 corresponding to the strong magnetic block 302 is fixedly provided in the second storage slot. A handle 303 is fixedly provided on the outer side of the side wall of the storage box 3 away from the second storage slot 106. The handle 303 facilitates the rotation of the storage box 3. When the storage box 3 is closed, the strong magnetic block 302 and the strong magnetic block 2 are attracted tightly to prevent the storage box 3 from rotating. The power cord or spare gas supply pipe can be placed inside the storage box 3, which improves the storage function of the oxygen concentrator.

[0069] The oxygen generating assembly includes a compressor 9, with a filter 7 at the air inlet of the compressor 9. The air outlet of the compressor 9 is connected to the air inlet of the adsorption tower 5. The air outlet of the adsorption tower 5 is connected to the air inlet of the gas storage tank 8. The air outlet of the gas storage tank 8 is connected to the air inlet of the humidification bottle 12 through a gas flow regulating valve 11. The air outlet of the humidification bottle 12 is connected to the gas supply pipe.

[0070] There are two adsorption towers 5, namely a first adsorption tower and a second adsorption tower. The air inlets of both the first and second adsorption towers are connected to the air outlet of the compressor 9 through a two-position four-way valve 10. The air outlets of both the first and second adsorption towers are connected to the air inlet of the air storage tank 8. One-way valves are provided on the air outlets of the first and second adsorption towers. A silencer 6 is provided on the two-position four-way valve 10.

When the two-position four-way valve 10 is in the first working position, the air inlet of the first adsorption tower is connected to the air outlet of the compressor 9, and the air inlet of the second adsorption tower is connected to the air inlet of the silencer 6. When the two-position four-way valve 10 is in the second working position, the air inlet of the second adsorption tower is connected to the air outlet of the compressor 9, and the air inlet of the first adsorption tower is connected to the air inlet of the silencer 6. The easy-to-store oxygen concentrator also includes a frame 4, with the housing 1 fixedly installed on the outside of the frame 4. The frame 4 includes a base plate 402, a partition 403, and two vertical mounting plates 401. The lower ends of the two vertical mounting plates 401 are fixedly connected to the two ends of the base plate 402, and the two ends of the partition 403 are fixedly connected to the middle ends of the two vertical mounting plates 401, respectively.

The air blown by the cooling fan plays a role in cooling the gas storage tank 8.

[0071] The compressor 9 adopts, but is not limited to, the existing Zhejiang Weibang Compressor Technology Co., Ltd.'s dispersion-type oil-free air compressor vehicle-mounted small air compressor 9BST1800-4AF; the adsorption tower 5 adopts, but is not limited to, the existing zeolite molecular sieve type adsorption tower 5, which is equipped with zeolite molecular sieves inside. The zeolite is used to adsorb nitrogen under high pressure and release nitrogen under normal pressure; the flow regulating valve 11 adopts, but is not limited to, the existing kofloc gas cylinder regulator flow meter model RK4400.

[0072] The two-position four-way valve 10 uses, but is not limited to, the existing Rexroth solenoid directional valve with two-position four-way coil 4WE6D62 / EG24N9K4 solenoid valve; the silencer 6 is usually composed of a shell, sound-absorbing material, and internal structure. The shell is the outer protective shell of the entire silencer 6, which can prevent dust and debris from entering the silencer 6. The internal sound-absorbing material (such as foam, glass fiber cotton, etc.) is used to absorb the sound wave energy generated when the gas is discharged, thereby reducing the propagation of noise. The internal structure of the silencer 6 is usually designed as a labyrinth type or sound-absorbing plate type to increase the propagation path of sound waves in the sound-absorbing material and improve the sound absorption effect. The humidification bottle 12 uses, but is not limited to, the Changjing oxygen humidification bottle 12 hospital ward bedside oxygen inhaler oxygen inhalation device humidification device. The filter 7 uses, but is not limited to, the existing Langfang Sener Filter Material Co., Ltd. compressor 9 air filter 7 model A158 dryer filter element.

[0073] The flow regulating valve 11, compressor 9, filter 7, adsorption tower 5, two-position four-way valve 10, silencer 6, gas storage tank 8, gas-liquid separator, and humidification bottle 12 are all existing technologies, and their specific structures and connection methods will not be described here.

[0074] In some other embodiments, the oxygen generation component uses a single zeolite adsorption tower 5 to prepare gas with a high oxygen concentration. The use of a single zeolite adsorption tower 5 to prepare gas with a high oxygen concentration is prior art and will not be described in detail here.

[0075] The vibration damping assembly 13 includes: a mounting plate 1301, which is fixedly connected to the base plate 402; a guide bolt 1304, which passes through the mounting plate 1301 and the mounting seat 901 in sequence and is threadedly connected to a nut 1305; and a compression spring 1306, which is located between the mounting plate 1301 and the mounting seat 901. The vibration damping assembly 13 also includes an upper damping ring 1303 and a lower damping ring 1307. The upper damping ring 1303 is installed between the compression spring 1306 and the mounting seat 901, and a positioning tube is fixedly provided at the lower end of the upper damping ring 1303. The positioning tube is located inside the compression spring 1306, and the guide bolt 1304 is located inside the positioning tube. The lower damping ring 1307 is installed between the compression spring 1306 and the mounting plate 1301, and the lower damping ring 1307 is fixedly connected to the mounting plate 1301. The upper end face of the damping ring has an annular groove, and the lower end of the compression spring 1306 is installed inside the annular groove. A washer is provided between the lower damping ring 1307 and the head of the guide bolt 1304. A second washer is fixed to the lower end of the upper damping ring 1303, and a limiting tube 1302 corresponding to the first washer is fixed to the lower end of the second washer. The limiting tube 1302 is installed on the outside of the guide bolt 1304. Both the upper damping ring 1303 and the lower damping ring 1307 are made of rubber. When the compressor 9 vibrates during rotation, and there is relative displacement between the mounting base 901 and the mounting plate 1301, the compression spring 1306 is further compressed. The rubber upper damping ring 1303 and the lower damping ring 1307 act as dampers, reducing noise and vibration during the operation of the oxygen concentrator. The limiting tube 1302 acts as a limiter, preventing the mounting base 901 from getting too close to the mounting plate 1301.

[0076] Work process:

[0077] When this scheme is implemented, external air enters the compressor 9 through the filter 7. The filter 7 filters out the dust in the air. The compressor 9 compresses the air into high-pressure air. The high-pressure air enters the adsorption tower 5, where nitrogen in the high-pressure air is adsorbed to become a gas with a high oxygen concentration. The gas with a high oxygen concentration enters the gas storage tank 8 for storage. Then, after the flow rate is regulated by the gas flow regulating valve 11, it is humidified and cooled by the humidification bottle 12 and then supplied to people for breathing through the gas supply pipe.

[0078] The setup of two adsorption towers 5 ensures a timely oxygen supply. The specific method is as follows: When the two-position four-way valve 10 is in the first working position, the inlet of the first adsorption tower is connected to the outlet of the compressor 9, and the inlet of the second adsorption tower is connected to the inlet of the silencer 6. At this time, compressed gas enters the first adsorption tower to adsorb nitrogen, and the high-oxygen-concentration gas enters the storage tank 8 for storage. Due to the one-way valve, the second adsorption tower releases the adsorbed nitrogen at atmospheric pressure, and the nitrogen is discharged to the outside through the silencer 6, which reduces the noise of the gas discharge. When the two-position four-way valve 10 is in the second working position, the inlet of the second adsorption tower is connected to the outlet of the compressor 9, and the inlet of the first adsorption tower is connected to the inlet of the silencer 6. The process is similar to the above. By alternating the use of the first and second adsorption towers, an uninterrupted oxygen supply can be achieved, improving the stability of the oxygen supply.

[0079] By setting up storage slot 103 and storage slot 2 106, it is convenient to store the power cord and spare gas supply pipe, avoiding the loss caused by inconvenient storage of the power cord and spare gas supply pipe, and improving the user experience.
