Abstract
Description
Technical Field
[0001] The utility model relates to an oxygen concentrator, in particular to a power supply structure of a dual-purpose oxygen concentrator. Background Art
[0002] Currently, dual-use oxygen concentrators for both vehicle and home use have two power supply options: one uses 12V DC power, which is then converted to 220V AC power by a built-in inverter to start the concentrator; the other uses 220V household electricity directly for startup. However, because these two power supply options utilize different plug-in connectors, if the user mistakenly connects both connectors simultaneously, the power supply board may experience abnormal power supply and may even burn out, resulting in poor safety. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a power supply structure for a dual-purpose oxygen concentrator.

[0005] A power supply structure for a dual-purpose oxygen concentrator includes a base of the oxygen concentrator, a power connection bracket installed on the base, a vehicle interface and a home interface installed in the power connection bracket, a front plate extending vertically upward is provided on the front end surface of the base, and a power supply space is provided on the front end surface of the front plate to expose the vehicle interface and the home interface; a sliding groove is formed between the front plate and the power connection bracket, a baffle is installed in the sliding groove, and after assembly, the baffle slides in the sliding groove to close the vehicle interface or the home interface.
[0006] Both ends of the front plate extend inwardly to form limit plates.
[0007] A limiting portion extending laterally outward is provided on the front side of the upper end of the power connection bracket. After assembly, the upper end of the baffle abuts against the bottom of the limiting portion.
[0008] The bottom of the limiting portion is provided with two symmetrically downwardly protruding positioning portions, and the upper end of the baffle is provided with positioning grooves corresponding to the positioning portions. After assembly, the positioning portions are located in the positioning grooves.
[0009] The front end surface of the baffle is provided with two symmetrical toggle grooves, and after assembly, the toggle grooves are exposed in the power supply space.
[0010] A voltage mark is provided on the front end surface of the baffle.
[0011] Both ends of the power connection bracket are provided with fixing parts, and the fixing parts are provided with through holes. The base is provided with fixing columns corresponding to the fixing parts, and threaded holes are provided in the fixing columns. After assembly, screws pass through the through holes and are threadedly connected with the threaded holes.
[0012] The beneficial effects of the present invention are as follows: the present invention has a power connection bracket mounted on the base, the base is provided with a front plate, a sliding groove is formed between the front plate and the power connection bracket, and a baffle is mounted in the sliding groove. After assembly, the baffle slides in the sliding groove to close the vehicle interface or the household interface. Thus, one of the power interfaces remains exposed and the other remains closed, preventing the two power interfaces from being connected to power at the same time, preventing the occurrence of board burnout, and improving safety.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.
[0023] Some embodiments of the present invention are described below with reference to the accompanying drawings.
[0024] Reference Figures 1 to 6A power supply structure for a dual-purpose oxygen concentrator includes a base 1 of the oxygen concentrator, a power connection bracket 2 mounted on the base 1, a vehicle interface 21 and a home interface 22 mounted in the power connection bracket 2, a front panel 11 extending vertically upwards provided on the front end face of the base 1, a power supply space 12 exposing the vehicle interface 21 and the home interface 22; a sliding groove 13 is formed between the front panel 11 and the power connection bracket 2, a baffle 3 is mounted in the sliding groove 13, and after assembly, the baffle 3 slides in the sliding groove 13 to close the vehicle interface 21 or the home interface 22. This allows one of the power interfaces to be exposed and the other to be closed, preventing users from connecting both power interfaces to power at the same time, thereby preventing the occurrence of burnout and improving safety.
[0025] The ends of the front plate 11 extend inward to form limit plates 14, which are used to prevent the baffle 3 from sliding out of the left and right ends of the sliding groove 13. As a further improvement of the utility model, the front side of the upper end of the power connection bracket 2 is provided with a limit portion 23 extending laterally outward. After assembly, the upper end of the baffle 3 abuts the bottom of the limit portion 23, further preventing the baffle 3 from falling out of the upper end of the sliding groove 13.
[0026] In the present invention, the bottom of the stopper 23 is provided with two symmetrically downwardly projecting positioning portions 24. The upper end of the baffle 3 is provided with a positioning groove 31 corresponding to the positioning portions 24. After assembly, the positioning portions 24 are located within the positioning grooves 31. When the user slides the baffle 3, the positioning portions 24 slide into the positioning grooves 31, and the user can clearly feel the sliding resistance, clearly knowing that the baffle has slid into the appropriate position, which facilitates use. Moreover, during use, the baffle 3 can maintain a stable structure in its natural state.
[0027] The front face of the baffle 3 is provided with two symmetrical toggle grooves 32. After assembly, the toggle grooves 32 are exposed in the power supply space 12, facilitating user adjustment and sliding. In this embodiment, the front face of the baffle 3 is provided with a voltage indicator. The voltage indicator indicates the corresponding plug-in voltage of the vehicle interface 21 and the home interface 22, providing convenience for users and preventing misoperation.
[0028] The two ends of the power connection bracket 2 are provided with fixing parts 25, and the fixing parts 25 are provided with through holes. The base 1 is provided with fixing columns 15 corresponding to the fixing parts 25, and threaded holes are provided in the fixing columns 15. After assembly, the screws pass through the through holes and are threadedly connected with the threaded holes, which facilitates assembly.
[0029] Reference Figure 7The present invention uses a sliding baffle 3 to restrict one power port to an exposed state and the other to a closed state, preventing both ports from being connected to power at the same time. The home port is directly connected to the power board, while the vehicle port is connected to the power board via a voltage inverter, enabling a dual-use oxygen concentrator for both vehicle and home use, providing users with the freedom to choose.
