At present, the PSA molecular sieve adsorption oxygen production technology is relatively mature, and the oxygen production efficiency and purity are relatively high, and the continuous oxygen production requirement can be met.

[0003] In recent years, with the rapid development of large-scale industrial oxygen production equipment technology, small oxygen production equipment has also gradually developed, and plays a positive role in household use or in the treatment of cardiovascular and cerebrovascular diseases, respiratory system diseases and chronic obstructive pulmonary diseases. Patent application number "202322477780.6" introduces a mobile oxygen generator, which mainly improves the support and effectively improves the practicability and stability of the mobile oxygen generator and increases the service life of the pulley.

However, the oxygen generator structures introduced in the above patents are relatively complex, high in cost and large in size, and simplifying the internal structure of the oxygen generator can reduce the cost, so that the small oxygen generator has greater development and application prospects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a small portable oxygen generator, comprising a housing, wherein an air pump is provided at the bottom of the housing; the air pump is connected to the bottom of a first adsorption tower and a second adsorption tower via an air inlet pipe, and a first lower solenoid valve and a second lower solenoid valve are respectively provided on the air inlet pipe; an air outlet pipe is provided at the top of the first adsorption tower and the second adsorption tower, and a first upper solenoid valve and a second upper solenoid valve are respectively provided on the air outlet pipe, and an oxygen outlet is provided at the end of the air outlet pipe; a control cabinet is provided on the surface of the housing, and a touch screen is provided on the control cabinet; and casters are also provided at the bottom of the housing.

[0006] As an improvement, the enclosure has a square, detachable, and sealed structure and consists of six panels.

[0007] As an improvement, a heat dissipation grille is provided below one side panel of the enclosure.

[0008] As an improvement, both the first adsorption tower and the second adsorption tower are cylindrical structures with equal diameters, and both are sealed with flange covers at the top and bottom.

[0009] As an improvement, both the first and second adsorption towers are filled with oxygen-generating molecular sieves.

[0010] As an improvement, a pressure equalization pipeline is provided in the middle of the gas outlet pipeline, and a pressure equalization regulating valve is provided on the pressure equalization pipeline.

[0011] As an improvement, the control cabinet is equipped with a PLC control system, which connects to various solenoid valves to realize the cyclic operation of adsorption and regeneration between the first adsorption tower and the second adsorption tower.

[0012] As an improvement, the casters are omnidirectional wheels, and there are four in total, evenly distributed at the four corners of the bottom of the box, with the two rear casters equipped with brake devices.

[0013] The beneficial effects of this utility model are as follows: A small, portable oxygen generator features a simple structure, small footprint, easy mobility, stable gas production, and low production cost. By installing an air pump inside the housing, the compressed gas directly enters two adsorption towers for adsorption and regeneration, eliminating the need for filtration and dehydration equipment, greatly simplifying the PSA oxygen generation process, resulting in a small-sized oxygen generator with low production costs. By installing an equalizing pipeline at the top of the adsorption tower and cooperating with a PLC control system for automatic control, continuous oxygen production can be achieved. In addition, four omnidirectional casters at the bottom facilitate the movement of the small oxygen generator, and a braking device ensures that the oxygen generator can be easily fixed to prevent slippage.

[0016] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a small portable oxygen generator according to this embodiment includes a housing 1, with an air pump 2 located at the bottom of the housing 1. The air pump 2 is connected to the bottom of a first adsorption tower 4 and a second adsorption tower 5 via an air inlet pipe 3, and a first lower solenoid valve 6 and a second lower solenoid valve 7 are respectively provided on the air inlet pipe 3. An air outlet pipe 8 is provided at the top of the first adsorption tower 4 and the second adsorption tower 5, and a first upper solenoid valve 9 and a second upper solenoid valve 10 are respectively provided on the air outlet pipe 8. An oxygen outlet 11 is provided at the end of the air outlet pipe 8. A control cabinet 12 is provided on the surface of the housing 1, and a touch screen 13 is provided on the control cabinet 12. Casters 14 are also provided at the bottom of the housing 1.

[0018] Furthermore, the housing 1 has a square, detachable, and sealed structure, consisting of six panels. The detachable structure facilitates the installation and connection of the internal air pump and pipelines, while the overall sealing allows for easy movement and enhances the aesthetics. Specifically, a heat dissipation grille 15 is provided below one side panel of the housing 1. The height of the heat dissipation grille 15 corresponds to the position of the air pump 2, thereby dissipating the heat generated by the air pump during operation in a timely manner and ensuring good heat dissipation inside the housing.

[0019] Furthermore, both the first adsorption tower 4 and the second adsorption tower 5 are cylindrical structures with equal diameters, and are sealed with flange covers at the top and bottom, which facilitates production and molecular sieve filling. Specifically, both the first adsorption tower 4 and the second adsorption tower 5 are filled with oxygen-generating molecular sieves, which are used to achieve nitrogen and oxygen separation.

[0020] Furthermore, a pressure equalization pipeline 16 is provided in the middle of the air outlet pipeline 8, and a pressure equalization regulating valve 17 is provided on the pressure equalization pipeline 16; specifically, the pressure equalization regulating valve 17 is a manual regulating valve or an automatic regulating valve.

[0021] Furthermore, the control cabinet 12 is equipped with a PLC control system, which connects to various solenoid valves to realize the cyclic operation of adsorption and regeneration between the first adsorption tower 4 and the second adsorption tower 5. The overall gas production of the equipment is relatively small, but it can achieve continuous gas production.

[0022] Furthermore, the movable wheels 14 are omnidirectional wheels, and there are four in total, evenly distributed at the four corners of the bottom of the housing 1. The two rear movable wheels are equipped with brake devices. The omnidirectional wheels facilitate the movement of the small oxygen concentrator, while the brake devices keep the oxygen concentrator fixed and prevent slippage.

[0023] This utility model discloses a small, portable oxygen generator, which features simple structure, small footprint, easy mobility, stable gas production, and low production cost. Its working principle is as follows: First, turn on the power switch of the control cabinet 12 and start the oxygen production operation through the touch screen 13; then, the air pump 2 inside the lower part of the housing 1 starts to work, and the compressed air source is directly introduced into the first adsorption tower 4 for adsorption through the air inlet pipe 3, while the second adsorption tower 5 is regenerating at the same time. The adsorption and regeneration cycle is realized by the opening and closing of the electronic valve controlled by the PLC. The continuously qualified oxygen produced is transported to the oxygen outlet 11 through the air outlet pipe 8, and then transported to the gas-using terminal through the oxygen outlet 11.

[0024] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
