Description

Technical Field

[0001] This utility model belongs to the field of oxygen generators, and in particular relates to a power supply structure for an oxygen generator. Background Technology

[0002] A molecular sieve oxygen generator is a device that utilizes the adsorption properties of molecular sieves to separate and produce high-purity oxygen from the air. Its structure mainly includes an air compression assembly, a molecular sieve assembly, and an oxygen storage assembly. Air is filtered and compressed by the air compression assembly and enters the molecular sieve assembly with a double molecular sieve cylinder structure. The air is distributed through a gas distribution valve and enters one of the molecular sieve cylinders containing the molecular sieve. Nitrogen, carbon dioxide, and other gases in the air are adsorbed, and the outflowing gas is high-purity oxygen. When the molecular sieve cylinder reaches a certain saturation level, the gas distribution valve closes the air intake for backflushing and cleaning. The molecular sieve cylinder enters the cleaning stage to discharge waste gas, and the other molecular sieve cylinder begins operation. This cycle repeats continuously to provide oxygen.

[0003] While oxygen concentrators are currently used in the medical field, they are also gradually entering the home and outdoor market. For example, when people go to high-altitude areas to experience the unique scenery of nature, they may experience altitude sickness and other adverse symptoms when moving from low to high altitudes. In such cases, oxygen concentrators are needed to help the body provide the necessary oxygen.

[0004] In existing technologies, the power connection points of the control board and battery in oxygen concentrators are often concentrated in the locations of various electronic components, which poses safety hazards and is structurally unreasonable.

[0042] Please see Figures 1-5This embodiment provides a power supply structure for an oxygen concentrator, including a power module 2 and an oxygen concentrator body 1, which are snap-fitted together. The oxygen concentrator body 1 has at least two layers: an upper support 11 and a lower support 12. A first mounting area 110 is formed on the upper support 11, and a second mounting area 120 is formed on the lower support 12. Below the lower support 12, the oxygen concentrator body 1 has a mounting slot 10 for assembling the power module 2. A control mainboard 13 of the oxygen concentrator body 1 is positioned from the first mounting area 110 towards the second mounting area 120. At least one sensing unit is provided on the control mainboard 13 at the location corresponding to the first mounting area 110 for functional detection of the oxygen concentrator body 1. The control mainboard 13 extends at least into the mounting slot 10 at the location corresponding to the location of the control mainboard 13 in the second mounting area 120, forming a power connection terminal 130 for connecting to the power module 2. The second mounting area 120 is implemented as the mounting area for an air compression assembly 14. This utility model connects the power module 2 and the oxygen generator body 1 using a snap-fit ​​installation method, and designs the internal structure of the oxygen generator body 1 into upper and lower supports. The lower support 12 forms a space for assembling the power module 2, and the control motherboard 13 is designed to connect to the power module 2 across the layers. The first installation area for installing the sensor unit, the second installation area for installing the air compression component, and the power connection terminal for installing the power module are separated, thereby making the space utilization design and safety more reasonable.

[0043] The above constitutes the necessity for solving the technical problem of this application, and the following is a detailed description in conjunction with the accompanying drawings:

[0044] Please combine Figure 2 and Figure 3 In this embodiment, the internal space of the oxygen concentrator body 1 is arranged in layers by an upper bracket 11 and a lower bracket 12. A first mounting area 110 is formed on the upper bracket 11 for mounting components such as an oxygen concentration sensor and an oxygen flow controller after oxygen supply. A second mounting area 120 is formed on the lower bracket 12. A first mounting port 111 is provided on the upper bracket 11 facing the second mounting area 120, and a cooling fan is installed in the first mounting port 111. Furthermore, a heat dissipation vent 100 is provided on the casing of the oxygen concentrator body 1 at the location of the second mounting area 120, which works in conjunction with the cooling fan for heat dissipation. Since the fan itself has relatively low power, it can be located between the upper bracket 11 and the lower bracket 12 and electrically connected to the control main board 13.

[0045] The control board 13 is an integrated circuit board, serving as the circuit control board for the oxygen concentrator. In this embodiment, it is arranged across multiple layers. With the oxygen concentrator in its normal orientation as a reference, the control board 13 is vertically positioned. The control board 13 is mounted on the upper bracket 11 or the lower bracket 12, or partially mounted and fixed to the upper bracket 11 and partially fixed to the lower bracket 12; it can be installed using screws.

[0046] Please combine Figure 4 and Figure 5 In this embodiment, a sensing unit is provided in the upper half of the control motherboard 13, specifically in the first mounting area 110, for sensing and detecting the oxygen generator's functions. Further, this sensing unit includes an oxygen concentration sensor 1321, a respiration sensor 1322, and a pressure sensor 1323. Specifically, the respiration sensor 1322 and pressure sensor 1323 are located on the side of the control motherboard facing the first mounting area; the oxygen concentration sensor 1321 is located on the side of the control motherboard facing away from the first mounting area, with its inlet end 13211 and outlet end 13212 extending into the first mounting area. The sensing unit is integrated into a single area of ​​the control motherboard, facilitating integration and improving space utilization. Simultaneously, the inlet end 13211 and outlet end 13212 of the oxygen concentration sensor 1321 extend into the first mounting area through the gap between the control motherboard and the upper structure, improving the ease of connection and installation.

[0047] In this embodiment, the sensing unit on the control motherboard 13 is integrated in the first mounting area 110, thus it can be located away from the second mounting area 120 where the air compression assembly 14 is located, preventing damage caused by factors such as heat aging. Furthermore, the control motherboard 13 is also provided with a charging module 131, which has an externally positioned charging port that can be directly used to power the oxygen concentrator or to charge multiple power modules 2.

[0048] Furthermore, the control motherboard also features a program programming interface 1324, with its connector extending into the mounting slot to prevent contamination. Preferably, the program programming interface 1324 is a TYPE-C interface, located near the bottom of the control motherboard, with the connector facing downwards towards the mounting slot. This allows it to be sealed during battery installation to prevent dust contamination, eliminating the need for a dust cover and facilitating program reading and writing.

[0049] Please see Figure 3 In a preferred embodiment of this invention, the power module 2 has a snap-fit ​​groove 21 and is installed with the lower bracket 12 via a snap-fit ​​assembly 3. The snap-fit ​​assembly 3 includes a pivot seat 31, an elastic reset member 32, and a button 33. The pivot seat 31 is pivotally connected to the lower bracket 12 and forms a rotating pivot point.

The snap-fit ​​protrusion 311 extends into the mounting slot 10 and snaps into the snap-fit ​​groove 21 of the power module 2. The elastic reset member 32 is supported on the press-reset portion. The button 33 is located in the press-reset portion. Furthermore, a pivot groove 1230 is formed on the lower bracket 12, and a pivot shaft 310 is provided on the pivot seat 31, with the pivot shaft 310 installed within the pivot groove 1230.

[0050] In a preferred embodiment of this invention, the lower bracket 12 includes a horizontal section 121, two vertical support sections 122, and two extension sections 123. The vertical support sections 122 are located at the top of the horizontal section 121 and support the upper bracket 11. A second mounting area 120 is formed between the horizontal section 121 and the upper bracket 11. The two extension sections 123 are located at the bottom of the horizontal section 121 and form a mounting slot 10. The outward-facing extension section 123 has an opening for a mounting protrusion 311 to extend into the mounting slot 10. Furthermore, a pivot groove 1230 is formed on the extension section 123. A pivot shaft 310 on the pivot seat 31 is installed in the pivot groove 1230. An elastic reset member 32 is supported between the extension section 123 and the press-to-reset part. A button 33 is located on the press-to-reset part. Preferably, the elastic reset member 32 is a spring.

[0051] It should be noted that the lower support 12 can be composed of a plate, which can be a flat plate, an irregularly shaped plate, etc. Similarly, the horizontal section 121, the vertical support section 122, and the extension section 123 of the lower support can also be implemented as plate structures.

[0052] Furthermore, please combine Figure 1 and Figure 3 To facilitate the assembly of the power module 2, a guide groove 20 is provided on the side of the power module 2, and a guide protrusion 1231 that cooperates with the guide groove 20 is provided in the mounting slot 10 of the oxygen generator body 1. Furthermore, the guide protrusion 1231 can be provided on the side of the extension section 123 facing the mounting slot 10, and the guide protrusion 1231 can be a single-segment or multi-segment structure.

[0053] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
