[0048] Referring to Figures 1-8 , it is one embodiment of the utility model main frame module 10 and modular oxygen generator. As Figure 1 and Figure 2 shown, the oxygen generator of the embodiment is a modular oxygen generator, comprising a main frame module 10, and a compressor module 20, a molecular sieve module 30, a battery module 40 and other functional modules. The main frame module 10 is the main part of the modular oxygen generator, mainly used for connecting and supporting each functional module.

[0049] As Figures 3-8 shown, the main frame module 10 mainly comprises a main support 11, a circuit board 12, a fan 13, an oxygen storage tank 14 and an electric control board 15.

[0050] The main support 11 is composed of a base part 111, a vertical support part 112 and an upper support part 113.

[0051] The base part 111 is used to support the whole structure, the vertical support part 112 is vertically arranged on the base part 111, and the upper support part 113 is connected to the top end of the vertical support part 112 and located on one side thereof, so as to form the top structure of the oxygen generator. As Figure 4 and Figure 5 shown, the upper support part 113 is provided with an air inlet 1131 and an air outlet 1132, which can provide an air circulation channel.

[0052] In order to realize the modular installation of the core components of the oxygen generator, referring to Figure 2 , a first area A is formed between the vertical support part 112, the bottom surface of the upper support part 113 and the base part 111, which is used for installing the compressor module 20, and a second area B is formed between the other side of the vertical support part 112 and the base part 111, which is used for installing the molecular sieve module 30.

[0053] The main support 11 is arranged in sections, so that each functional module can be independently disassembled and replaced, thereby simplifying the maintenance process and improving the user's operation convenience.

[0054] The oxygen storage tank 14 is vertically arranged in the vertical support part 112 of the main support 11, so that the oxygen storage tank 14 can be compactly arranged in the main support 11 structure, thereby saving the transverse space of the equipment.

[0055] As shown in Figure 7 and Figure 8 , the circuit board 12 and the fan 13 are arranged in the upper support part 113 of the main support 11.

[0056] The circuit board 12 is mainly connected with the display screen 16, and is used to realize the touch display function. In addition, the circuit board 12 can further integrate electronic detection components such as pressure sensors and oxygen concentration sensors, to realize the sensing data acquisition function.

[0057] In this embodiment, as shown in Figure 4 , the display screen 16 is arranged at the top of the upper support part 113, and is located above the circuit board 12. The display screen 16 is a touch screen, and the user can more conveniently view the device state information such as oxygen flow, oxygen concentration, molecular sieve temperature and other important parameters through the display screen 16, and can also adjust the oxygen flow, breathing sensitivity and other data, and can realize simple device control through touch. The display screen 16 can also be a non-touch screen, and a plurality of operation buttons are arranged around the non-touch screen. The user can operate the operation buttons to make the non-touch screen display the corresponding device state information or adjust the oxygen flow, to realize the operation control of the oxygen generator.

[0058] The fan 13 drives the airflow to enter through the air inlet 1131 and is sent to the first area A through the air outlet 1132, to cool the airflow delivered to the compressor module 20 in the first area A. The airflow flowing through the upper support part 113 can also cool the circuit board 12.

[0059] The electric control board 15 is arranged in the base part 111, and is used to electrically control the oxygen generator. The electric control board 15 can control the operating parameters of the oxygen generator, such as electrically controlling the fan 13, the compressor module 20 and the molecular sieve module 30, to ensure the stable operation of the system under different working conditions.

[0060] The main frame module 10 is provided with independent mounting areas on both sides of the main support 11, so that the molecular sieve module 30 and the compressor module 20 can be independently mounted and quickly disassembled, the independence of each module is improved, and the replacement and maintenance operations are simplified; meanwhile, through the optimization of the space layout, not only efficient connection and support are provided for each functional module, but also the heat dissipation efficiency of the equipment is improved; in addition, the oxygen storage tank 14 is vertically arranged in the main support 11, so that the internal space of the oxygen generator is further saved, the equipment is more compact, and the overall performance and use convenience of the oxygen generator are improved.

[0061] In the embodiment, the circuit board 12 is supported at the top end of the oxygen storage tank 14, and the oxygen storage tank 14 can support the circuit board 12.

[0062] Further, the fan 13 is arranged below the circuit board 12 and directly above the first area A. The circuit board 12 is located in the heat dissipation air duct of the upper frame part 113, and the heat generated by the circuit board 12 can be carried away by the air flow in the air duct, so that the working temperature of the circuit board 12 can be effectively reduced, thereby prolonging the service life of the circuit board 12 and improving the stability and reliability of the system. The fan 13 directly blows air downward to the first area A, thereby improving the heat dissipation effect of the compressor module 20. The installation position of the fan 13 ensures that the compressor module 20 can directly receive the cooling air flow of the fan 13, thereby effectively reducing the operating temperature of the compressor and prolonging the service life of the compressor.

[0063] In the embodiment, as shown in Figure 7 and Figure 8 , the base part 111 is protruded upward at the lower end of the second area B to form a boss structure 1111. The boss structure 1111 is higher than the other side of the base part 111 and internally installs the electric control board 15. The arrangement of the boss structure 1111 not only can reasonably support the molecular sieve module 30, but also can make full use of the internal space of the boss structure 1111 by arranging the electric control board 15 in the boss structure 1111, so that the overall layout of the equipment is more reasonable.

[0064] Further, referring to Figure 4 , a gap a is arranged between the oxygen storage tank 14 and the inner wall of the vertical frame part 112, and the first area A is communicated with the second area B through the gap a. The gap a between the oxygen storage tank 14 and the vertical frame part 112 enables the first area A (for mounting the compressor module 20) and the second area B (for mounting the molecular sieve module 30) to be in air flow communication, so that the heat dissipation air flow generated during the operation of the compressor can flow to the molecular sieve module 30 through the gap a, thereby preheating and temperature compensating the molecular sieve module 30 and improving the working efficiency of the molecular sieve module 30. In addition, the gap a can also improve the heat dissipation effect of the compressor through natural air flow.

[0065] In order to facilitate the installation and disassembly of the compressor module 20, the base part 111 is provided with a first clamping groove limiting piece 1112, which can be clamped and limited with the compressor module 20. In the embodiment, the compressor module 20 can slide horizontally along the length direction of the base part 111, and the first clamping groove limiting pieces 1112 are oppositely arranged on both sides of the base part 111 in the width direction, so as to form a sliding groove structure, which plays a role of positioning and guiding when the compressor module 20 is installed and disassembled, and plays a role of limiting after the compressor module 20 is installed in place, thereby effectively preventing vibration and displacement of the compressor module 20 during operation.

[0066] Similarly, in order to facilitate the installation and disassembly of the molecular sieve module 30, the vertical frame part 112 is provided with a second clamping groove limiting piece 1121, which can be clamped and limited with the molecular sieve module 30. In the embodiment, the molecular sieve module 30 can slide vertically along the length direction of the vertical frame part 112, and the second clamping groove limiting pieces 1121 are oppositely arranged on both sides of the vertical frame part 112, so as to form a sliding groove structure, which plays a role of positioning and guiding when the molecular sieve module 30 is installed and disassembled, and plays a role of limiting after the molecular sieve module 30 is installed in place, thereby effectively preventing vibration and displacement of the molecular sieve module 30 during operation.

[0067] In the embodiment, as shown in Figure 4 , the base part 111 located at the lower side of the first area A is provided with a first interface assembly 1113, which is a quick connection electric module of the compressor module 20, so as to realize the purpose of compressing air by the compressor module 20 and delivering pressurized air to the molecular sieve module 30. Figure 7 As shown in , the base part 111 located at the lower side of the second area B is provided with a second interface assembly 1114, which is a quick connection electric module of each valve group of the molecular sieve module 30. The circuit board 12 and the electric control board 15 can be connected through wires.

[0068] Figure 6 In order to facilitate the installation of each component in the main support 11 and simplify the production and manufacturing, the main support 11 is designed as a three-part structure: a support main body 1101, a support bottom cover 1102 and a support upper cover 1103. The support bottom cover 1102 and the support upper cover 1103 are tightly buckled at the bottom and the top of the support main body 1101, respectively.
