Description

Technical Field

[0001] The invention belongs to the field of oxygen generators, and in particular relates to a molecular sieve quick-disassembly assembly type oxygen generator. Background Art

[0002] Molecular sieve oxygen generator is a device that uses the adsorption characteristics of molecular sieves to separate and produce high-purity oxygen from the air. Its structure mainly includes air compression components, molecular sieve components and oxygen storage components. The air is filtered and compressed by the air compression component and enters the molecular sieve component with a double molecular sieve cylinder structure. The air is evenly distributed through the gas distribution valve and enters a molecular sieve cylinder equipped with molecular sieves. Nitrogen, carbon dioxide, etc. in the air are adsorbed, and the outflowing gas is high-purity oxygen. When the adsorption tower reaches a certain saturation, the gas distribution valve closes the air intake for backwashing and cleaning, and the adsorption tower enters the purge stage to discharge waste, and the other molecular sieve cylinder equipped with molecular sieves works, and this cycle is repeated for continuous oxygen supply.

[0003] At present, oxygen concentrators are used in the medical field and have gradually entered the home or outdoor fields. For example, people go to plateaus and other places to appreciate the unique scenery of nature. When people go from low altitudes to high altitudes, they will experience adverse symptoms such as altitude sickness. At this time, they need to use oxygen concentrators to help the body provide the required oxygen.

[0004] As oxygen generators have entered the consumer level and entered homes and outdoors, molecular sieves are consumables. Long-term use will reduce their oxygen production effect and affect user use. Therefore, the molecular sieves need to be replaced regularly. In existing traditional oxygen generators, the molecular sieve cylinder is set together with other components, and the structure is relatively complex. It is difficult for users to replace the molecular sieves by themselves. Usually, they need to return to the factory for processing by professional staff. However, returning to the factory not only increases the user's usage cost, but also increases the difficulty of the after-sales staff's work.

[0005] In order to reduce the difficulty of work for after-sales staff, Chinese patent CN 221788737 U discloses an oxygen concentrator layout structure, including a rear shell, a front shell, an upper shell, a base, a compressor, a compressor cover, an air intake silencer, an exhaust silencer, a molecular sieve cartridge, a fixed bracket, and an oxygen tank; the rear shell, the front shell, the upper shell and the base are combined together to form the shell of the oxygen concentrator; the rear shell and the compressor cover are fixedly arranged on the base, and the fixed bracket, the cooling fan and the molecular sieve cartridge are arranged on the top of the compressor cover; the cooling fan is arranged below the fixed bracket; the oxygen tank, the exhaust silencer and the two-position four-way valve are arranged above the fixed bracket; the molecular sieve cartridge is fixed on the side plate of the fixed bracket by a quick-release structure; the compressor and the exhaust silencer are arranged in the compressor cover, and the air intake silencer is arranged on the side of the compressor cover; the air inlet is arranged on the rear shell, and the air inlet corresponding to the air inlet on the inner side of the rear shell covers the air intake air path guide; the humidification bottle is arranged on the upper shell. In this solution, the molecular sieve cartridge is replaced as a whole, which reduces the difficulty for the staff to disassemble and install the molecular sieve cartridge. However, since the molecular sieve cartridge is closely connected to other components, it is difficult for the user to disassemble it by themselves, and returning it to the factory for repair will still increase the user's cost. Therefore, providing an oxygen concentrator with a reasonable design that is convenient for users to quickly disassemble and install the molecular sieve cartridge is an urgent problem to be solved by the present invention.

[0065] It should be noted that the oxygen generator is a device that physically separates oxygen through molecular sieves. Its principle is: first, the air intake of the equipment is filtered and compressed through the air compression component, and then the gas is distributed into the molecular sieve component through the gas distribution valve. The molecular sieve component includes two molecular sieve cylinders, which work alternately. The gas distribution valve passes the compressed gas into one of the molecular sieve cylinders. According to the different adsorption capacities of the molecular sieve for nitrogen and oxygen, the nitrogen is adsorbed and discharged, and then enters the oxygen storage tank; after working for a period of time, the gas distribution valve alternates with another molecular sieve cylinder to work, and the previous molecular sieve adsorption tower back-blows and discharges nitrogen, and so on. This is necessary for understanding the premise of this embodiment.

[0081] Then, a first mounting hole 11133 is provided on the connecting section 1113. Specifically, the first mounting hole 11133 is provided on the strip plate body 11131 of the connecting section 1113, and two or more holes can be vertically provided.

The mounting valve seat 132 has at least one second fitting concave surface 1322 that fits the convex surface of the arc-shaped plate body 11132 according to its size, so as to fit the convex surface of the arc-shaped plate body 11132 to form a tight fit, thereby making the best use of the installation space.

[0082] The gas distribution valve body 131 is located as a whole on the second bracket section 1112. Specifically, a mounting area 11121 of the gas distribution valve 13 is formed on the second bracket section 1112 near the connecting section 1113. The mounting area 11121 can be formed into a shallow groove area through a rib frame selection, which is used to limit the positioning of the gas distribution valve body 131. A limiting slot 11122 is also provided on the second bracket section 1112. Specifically, the limiting slot 11122 is arranged in the mounting area 11121.

A heat dissipation port 1120 is provided on the lower bracket 112 facing the quick-release docking port 10.

The air intake grille 213 is provided with an air intake filter on the inner side and / or the outer side. In this embodiment, the air intake grille 213 is preferably provided with an air intake filter on both the inner side and the outer side.

[0094] The first housing 211 and the second housing 212 are respectively assembled on both sides of the air intake grille 213. Specifically, air intake grille assembly holes 2130 are provided on both sides of the air intake grille 213, a first housing assembly hole 2110 is provided on one side of the first housing 211 close to the air intake grille 213, and a second housing assembly hole 2120 is provided on one side of the second housing 212 close to the air intake grille 213.

After the molecular sieve cartridge 24 separates oxygen, it returns to the first integrated docking support 12 from the equalizing valve 230 of the lower sieve seat 23 in conjunction with the air guide extension pipe 26, and then returns to the oxygen generator body 1 through the molecular sieve oxygen connector 252 docking the oxygen adapter 122, and finally passes through the oxygen injection valve 19 and the sensor assembly 16 as described above and enters the oxygen storage assembly 15. The gas distribution valve 13 is a two-position four-way solenoid valve, and it can also perform backwashing and exhaust of the molecular sieve cartridge 24 in turn through the air intake adapter 121 and the molecular sieve air intake connector 251 .

[0099] As mentioned above, see Fig.10 , the positions of the first assembly hole 120 and the second assembly hole 250 correspond, and the two can be assembled by screw through holes.

The above connectors can also correspond to the middle position of the quick-release docking interface 10 of the oxygen concentrator 1 as the height of the molecular sieve cylinder becomes lower, which is not considered as a limitation of this embodiment.

[0101] Beneficial effects of this embodiment: The present invention modularizes the molecular sieve and designs a quick-release interface, making it more convenient and efficient to replace the molecular sieve of the traditional oxygen concentrator; by integrating the air inlet and oxygen outlet mechanisms of the oxygen concentrator body and the molecular sieve module and docking them in a pluggable assembly manner, the time for replacing the molecular sieve is shortened, the convenience of replacement for users is improved, and the overall integration of the oxygen concentrator is improved, making the device more compact and beautiful.

[0102] A unique installation structure is designed, in which the upper bracket is set as a high-low spatial staggered structure, the molecular sieve cartridge is accommodated under the relatively high first bracket section, and the gas distribution valve is set in the relatively low second bracket section, thereby realizing a compact structural design, improving space utilization, and facilitating the replacement and docking of the molecular sieve cartridge as an integral module.

[0103] The interfaces of the oxygen generator body and the molecular sieve module are integrated with the gas distribution valve in one area for convenient and efficient docking.

[0104] The specific design of the upper bracket, combined with the structure for installing the valve seat and the molecular sieve cartridge, allows the molecular sieve cartridge, the upper bracket and the gas distribution valve to fit tightly together, further enhancing the stability and ease of installation of the device.

[0105] The gas distribution valve body is installed by installing the valve seat and the connecting section, and the bottom and the second bracket section are plugged and limited. The installation is carried out in a manner of first positioning and then assembling, which is stable and simple.

[0106] The nitrogen exhaust socket on the second bracket section is used for inserting the nitrogen exhaust pipe for installing the valve seat, so that the exhaust gas of the gas distribution valve body is discharged to the bottom of the upper bracket through the structure, and then discharged out of the oxygen generator. The nitrogen exhaust socket plays the role of nitrogen exhaust and can also be used to install the valve seat through the nitrogen exhaust pipe.

[0107] By designing the molecular sieve shell and the molecular sieve cylinder into a modular structure, users can quickly replace them, thereby reducing the downtime and maintenance costs of the oxygen generator and extending its service life; and the molecular sieve shell is hidden under the panel, making the overall structure more beautiful and integrated.

[0108] Through modular design, the molecular sieve cartridge can be quickly disassembled and installed, and the molecular sieve shell can be fully assembled and fixed after assembly through the slot, which facilitates overall disassembly and assembly.

[0109] Improve the convenience of molecular sieve replacement: The molecular sieve module is designed with a quick plug-in interface to facilitate users to quickly replace or maintain it.

[0110] Extend the service life of the equipment: Through independent modular design, ensure that the molecular sieve can be replaced in time, avoiding the failure of the molecular sieve in the pure integrated design and causing the overall failure of the equipment.

[0111] Improve maintenance efficiency: Quick docking and disassembly simplify the maintenance process and reduce user maintenance costs.

[0112] Furthermore, the present invention is described in detail above in conjunction with the embodiments of the accompanying drawings, and a person skilled in the art can make various variations of the present invention according to the above description.
