[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then further distilled to obtain oxygen.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a multifunctional oxygen concentrator to solve the problems existing in the above-mentioned prior art, which can fully screen out debris such as dust and cotton wool in the air and improve the air intake efficiency of the oxygen concentrator; and the air intake unit has the characteristics of self-cleaning and replaceability.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 2 As shown, the present invention provides a multifunctional oxygen concentrator, including a box body 1, an air intake unit is arranged in the box body 1, the end of the air intake unit is connected to the air compressor 7 through the air intake pipe 6, the output end of the air compressor 7 is provided with a molecular sieve 2, the output end of the molecular sieve 2 is connected to a gas storage bottle 10, a storage bin 8 is arranged on the box body 1, the oxygen inhalation equipment is stored in the storage bin 8, and the gas storage bottle 10 is connected to the oxygen inhalation equipment through an oxygen pipeline; the air intake unit includes a plurality of air intake filter mechanisms 5, the plurality of air intake filter mechanisms 5 are detachably installed on the air intake side of the box body 1, and the ends of the air intake filter mechanisms 5 are connected to the air intake pipe 6.

[0023] The air intake filter mechanism 5 includes an air intake channel 16, an air intake filter and an air intake fan. The air intake channel 16 is detachably installed on the air intake side of the housing 1, and the air intake filter and the air intake fan are sequentially assembled in the air intake channel 16 along the air flow direction.

[0024] In one embodiment, the air intake filter includes a primary filter 11 and a secondary filter 14 , the primary filter 11 and the secondary filter 14 are arranged at intervals along the air flow direction, and a plurality of spiral air intake pipes 12 are arranged between the primary filter 11 and the secondary filter 14 .

[0025] The primary filter 11 is mounted on the outermost side of the air inlet of the air inlet passage 16, the air inlets of the multiple spiral air inlet pipes 12 are spaced apart on the front mounting plate, and the air outlets of the multiple spiral air inlet pipes 12 are spaced apart on the rear mounting plate. After being initially filtered by the primary filter 11, the air enters the air inlet passage from the multiple spiral air inlet pipes 12; the front mounting plate and the rear mounting plate are fixed to the inner wall of the air inlet passage 16. The multiple spiral air inlet pipes 12 are staggered in the air inlet passage 16, the diameter of the front section of the spiral air inlet pipe 12 gradually decreases, and the diameter of the rear section of the spiral air inlet pipe 12 gradually increases.

[0026] During assembly, the air inlet and air outlet of the spiral air inlet pipe 12 are first assembled on the front mounting plate and the rear mounting plate respectively, and then the spiral air inlet pipe 12 is assembled as a whole into the air inlet passage 16, and finally the primary filter 11 is installed to the outermost side of the air inlet passage 16. The primary filter 11 performs preliminary filtration on the air, and the air after preliminary filtration enters from the air inlet of the spiral air inlet pipe 12. The inner wall of the spiral air inlet pipe 12 is evenly distributed with flexible fiber burrs. Impurities in the air and cotton wool that is not filtered out by the primary filter 11 will be blocked by the flexible fiber burrs. However, as the use time of the oxygen generator increases, impurities sticking to the flexible fiber burrs will easily cause blockage of the spiral air inlet pipe 12. Therefore, in the present embodiment, the spiral air intake pipe 12 is divided into a front section and a rear section. The diameter of the front section gradually decreases, which is beneficial to filtering impurities, and the diameter of the rear section gradually increases. Under the negative pressure of the air intake fan, the air flow rate of the rear section can be increased, thereby clearing the impurity blockage in the front section. The blocked impurities are filtered and collected again by the secondary filter 14 under the negative pressure of the rear section.

[0027] In one embodiment, the air intake fan includes a primary air intake fan 15 and a secondary air intake fan 17, and the primary air intake fan 15 and the secondary air intake fan 17 are arranged at intervals on the rear side of the air intake filter in the air intake channel 16. In order to prevent the spiral air intake pipe 12 from being blocked, two air intake fans are arranged in this embodiment, which can not only increase the air intake volume, but also provide effective air circulation pressure for the spiral air intake pipe 12 to prevent impurities from blocking the spiral air intake pipe 12.

[0028] In one embodiment, a vibration motor 13 is installed at the top of the air inlet channel 16, the diameter of the air inlet side of the air inlet channel 16 is larger than the diameter of the air outlet side, and the channel side wall of the air inlet channel 16 is inclined; the bottom of the air inlet channel 16 is a grille structure, and a dust collecting tank 18 is also provided at the bottom of the air inlet channel 16. When the oxygen generator is in a non-oxygen generating state, the oxygen generator can be cleaned regularly, and the vibration motor 13 is started. The vibration motor 13 will drive the first-level filter 11, the second-level filter 14, the first-level air inlet fan 15 and the second-level air inlet fan 17 to vibrate, thereby vibrating impurities and dust to fall, and the impurities fall into the dust collecting tank 18 through the grille, and then the dust collecting tank 18 is pulled out to clean the dust and impurities.

[0029] In one embodiment, an electrostatic precipitator chamber 3 is also provided in the air intake unit, and a plurality of air intake filter mechanisms 5 are detachably installed in the air intake filter cabin 4. The end of the air intake filter cabin 4 is connected to the electrostatic precipitator chamber 3. After the air is filtered by the air intake filter mechanism 5, it enters the electrostatic precipitator chamber 3, and the residual fine dust and static electricity are eliminated by the electrostatic precipitator. After the electrostatic precipitator, the air is transported to the air compressor 7 through the air intake pipe 6.

[0030] In one embodiment, a barometer is provided on the top of the gas cylinder 10, and an ultraviolet sterilization lamp is provided in the storage bin 8. When the oxygen concentrator needs to be used, the door of the storage bin 8 is opened, the oxygen mask 9 is taken out and worn, and then the gas cylinder 10 starts to deliver oxygen to the oxygen mask 9 through the switch on the oxygen mask 9 or the remote control (the switch of the oxygen mask 9, the remote control setting, and the gas outlet of the gas cylinder 10 are all conventional technologies in the field of oxygen concentrators, and will not be described in detail here). After oxygen inhalation is completed, the oxygen mask 9 is put back into the storage bin 8. At this time, the ultraviolet sterilization lamp in the storage bin 8 works to sterilize the oxygen mask 9 for a specified period of time.

[0031] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
