[0053] Reference Figures 1-8 , an embodiment of the utility model main frame module 10 and oxygen generator. The oxygen generator of the embodiment is a modular oxygen generator, which comprises 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.

[0054] The main frame module 10 comprises a main support 11, an oxygen storage tank 14 arranged in the main support 11, a control assembly and a fan 13.

[0055] As Figure 3 , the main support 11 is composed of a base part 111, a vertical support part 112 and an upper support part 113.

[0056] The base part 111 is used for supporting 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 of the vertical support part 112, so as to form the top structure of the oxygen generator. Among them, the upper support part 113 is provided with an air inlet 1131 and an air outlet 1132, which can provide an air circulation channel.

[0057] In order to realize the modular installation of the core components of the oxygen generator, a first area A is formed between one side of the vertical frame part 112, the bottom surface of the upper frame part 113 and the base part 111, for installing the compressor module 20, and a second area B is formed between the other side of the vertical frame part 112 and the base part 111, for installing the molecular sieve module 30.

[0058] The main support 11 can realize independent disassembly and replacement of each functional unit through the layout of the partition, thereby simplifying the maintenance process and improving the operation convenience of the user.

[0059] As shown in Figure 4 and Figure 5 , the oxygen storage tank 14 is vertically arranged in the vertical frame part 112 of the main support 11, so that the oxygen storage tank 14 can be compactly arranged in the structure of the main support 11, saving the transverse space of the equipment.

[0060] The control assembly and the fan 13 are arranged in the upper frame part 113 of the main support 11.

[0061] 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, and the airflow flowing through the upper frame part 113 can also dissipate heat for the control assembly.

[0062] The above-mentioned main frame module 10 is provided with independent installation areas on both sides of the main support 11, realizing independent installation and quick disassembly of the molecular sieve module 30 and the compressor module 20, improving the independence of each module, simplifying the replacement and maintenance operation; at the same time, 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, further saving the internal space of the oxygen generator, making the equipment more compact, which helps to improve the overall performance and use convenience of the oxygen generator; the control assembly is arranged in the heat dissipation air duct of the upper frame, which can use the air flow in the air duct to take away the heat generated by the control assembly, improving the stability and reliability of the system.

[0063] In the present embodiment, the control assembly includes a main control board 12, which integrates a display and detection unit and an electronic control unit.

[0064] The display and detection unit is responsible for touch operation and data acquisition, so that the user can monitor the state of the oxygen generator in real time. Specifically, in the present embodiment, a display screen 16 is arranged at the top of the upper frame part 113, and the display screen 16 is located above the main control board 12. The display screen 16 is a touch screen, and the user can more conveniently check the equipment state information such as oxygen concentration, temperature, pressure and other important parameters through the display screen 16, and can realize simple equipment control through touch.

[0065] The electronic control unit controls the operation parameters of the oxygen generator, such as the electrical control of the fan 13, the compressor module 20, and the molecular sieve module 30, to ensure stable operation of the system under different working conditions.

[0066] In addition, the main control board 12 is arranged in the heat dissipation air duct of the upper frame, and the heat generated by the main control board 12 can be carried away by the air flow in the air duct, so as to effectively reduce the working temperature of the main control board 12, thereby prolonging the service life of the main control board 12 and improving the stability and reliability of the system.

[0067] Referring to Figure 8 , the main frame module 10 is further provided with an auxiliary oxygen storage tank 15, which is arranged in the base portion 111 and is in series communication with the oxygen storage tank 14. The connection between the two can be connected by a sealing rubber pad. The auxiliary oxygen storage tank 15 can not only make full use of the space of the existing structure of the equipment to increase the gas storage effect, but also can provide additional oxygen reserve under the condition of high load of the equipment or increased oxygen demand, thereby maintaining the stability of oxygen supply.

[0068] This double oxygen storage design greatly enhances the continuous oxygen supply capacity of the oxygen generator through the linkage work of the oxygen storage tank 14 and the auxiliary oxygen storage tank 15, effectively reduces the problem of insufficient oxygen supply of the equipment under high demand. At the same time, the auxiliary oxygen storage tank 15 is arranged in the base portion 111, so that the structure of the equipment is more compact and reasonable, and the space utilization rate of the main frame module 10 is further improved.

[0069] In the embodiment, as shown in Figure 7 and Figure 8 , the base portion 111 is raised in the lower direction of the second region B to form a boss structure 1111. The boss structure 1111 is higher than the other side of the base portion 111 and internally installs the auxiliary oxygen storage tank 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 auxiliary oxygen storage tank 15 in the boss structure 1111, so that the overall layout of the equipment is more reasonable.

[0070] In the embodiment, as shown in Figure 7 , one end of the main control board 12 is located above the oxygen storage tank 14. Since electronic components need to be installed on the main control board 12, a certain gap b is left between the top of the gas tank and the main control board 12. At the same time, the upper part of the molecular sieve module 30 is provided with an auxiliary air inlet, and the outer shell of the molecular sieve module 30 is provided with an auxiliary air inlet 31 which is in communication with the auxiliary air inlet. The auxiliary air inlet is in communication with the gap b, and a certain heat dissipation effect is achieved by using the auxiliary air inlet.

[0071] In order to improve the heat dissipation effect of the compressor module 20 and the control assembly, the fan 13 of the present embodiment is arranged below the control assembly and directly above the first area A. 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.

[0072] Further, referring to Figure 4 , the oxygen storage tank 14 and the inner wall of the vertical frame part 112 are provided with a gap a, 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 installing the compressor module 20) to be in air flow communication with the second area B (for installing the molecular sieve module 30). 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 also improves the heat dissipation effect of the compressor through natural air flow.

[0073] In order to facilitate the installation and removal of the compressor module 20, at least one first clamping groove limiting part 1112 is arranged on the base part 111 and can be clamped and limited with the compressor module 20. In the present embodiment, the compressor module 20 can slide horizontally along the length direction of the base part 111, and the first clamping groove limiting parts 1112 are arranged on the two opposite sides of the base part 111 in the width direction to form a sliding groove structure, thereby playing a positioning and guiding role when the compressor module 20 is installed and removed, and also playing a limiting role after the compressor module 20 is installed in place, thereby effectively preventing the vibration and displacement of the compressor module 20 during operation.

[0074] Similarly, in order to facilitate the installation and removal of the molecular sieve module 30, at least one second clamping groove limiting part 1121 is arranged on the vertical frame part 112 and can be clamped and limited with the molecular sieve module 30. In the present 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 parts 1121 are arranged on the two opposite sides of the vertical frame part 112 to form a sliding groove structure, thereby playing a positioning and guiding role when the molecular sieve module 30 is installed and removed, and also playing a limiting role after the molecular sieve module 30 is installed in place, thereby effectively preventing the vibration and displacement of the molecular sieve module 30 during operation.

[0075] In the present embodiment, as shown in Figure 5 , the upper frame part 113 located on the upper side of the first area A is provided with a first interface assembly 1113, which is a quick connection electrical module of the compressor module 20, so as to achieve the purpose of compressing air by the compressor module 20 and delivering pressurized air to the molecular sieve module 30. As shown in Figure 8As shown, the base part 111 under 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.

[0076] Referring to Figure 7 In order to facilitate the installation of each component in the main support 11 and simplify the production and manufacturing thereof, 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 to the bottom and the top of the support main body 1101, respectively.

[0077] The utility model also includes a kind of modular oxygen generator, including compressor module 20, molecular sieve module 30, battery module 40 and above-mentioned main frame module 10. Compressor module 20 and molecular sieve module 30 are respectively with main frame module 10 detachably connected;Battery module 40 is located at the bottom of main frame module 10, and is fixedly connected or detachably connected with main frame module 10.

[0078] The above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, for those skilled in the art, the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the utility model.
