Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment technology, and in particular to a gas filter for an oxygen generator. Background Technology

[0002] Oxygen is a crucial substance for human metabolism and is essential for human life. Inhaling oxygen can alleviate discomfort caused by hypoxia, promote recovery, and prevent the condition from worsening. Supplementing with oxygen in the hypoxic environment of high altitudes can alleviate various illnesses caused by high-altitude hypoxia, such as poor sleep, endocrine disorders, weakened immunity, and myocardial hypertrophy.

[0003] Existing small oxygen concentrators require compressed air purification during oxygen production, currently achieved by placing filters at the air compressor inlet. However, this method fails to dry the moisture in the gas, resulting in high moisture content in the gas entering the molecular sieve. This affects the molecular sieve's lifespan and adsorption capacity, consequently impacting the oxygen concentrator's performance. Maintaining a consistent oxygen concentration necessitates frequent molecular sieve replacements, increasing costs. Furthermore, the existing oxygen concentrator filters are inconvenient to clean regularly and require cumbersome replacement, causing inconvenience during use.

[0004] For example, an oxygen generator with patent application number 202020296305.2 discloses "a device housing, a compressor disposed at the lower end of the housing, the housing and the compressor being connected by bolts, a silencer disposed at the upper end of the compressor, the compressor and the silencer being connected by bolts, a secondary filter disposed at the upper end of the silencer, the secondary filter and the compressor being connected by pipe fittings, a solenoid valve disposed on one side of the secondary filter, the secondary filter and the solenoid valve being connected by pipe fittings, a molecular sieve tower disposed on one side of the solenoid valve, the solenoid valve and the molecular sieve tower being connected by pipe fittings. The advantages are: this utility model has a high level of intelligence, high safety for users, good quality oxygen produced, and the design of handles and silent casters makes the device easier to move, making it highly practical." While the above structure can filter gas, it still suffers from inconvenience in cleaning and disassembling the filter, and cannot dry the moisture in the gas.

[0005] To address the aforementioned issues, we provide an oxygen generator gas filter that can filter dust and impurities from the gas entering the oxygen generator, dry the gas, and facilitate the replacement and cleaning of the filter mechanism. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a gas filter for oxygen generators.

[0007] The purpose of this utility model is achieved as follows: an oxygen generator gas filter includes a housing, a grille is provided on the right side of the housing, an air inlet pipe is provided on the left side of the housing, and a first filter mechanism and a second filter mechanism are provided inside the housing. The first filter mechanism filters impurities in the air, and the second filter mechanism dries moisture in the gas.

[0008] Furthermore, a fan is provided between the first filter mechanism and the second filter mechanism, and a second fan is provided inside the housing on the left side of the second filter mechanism.

[0009] Furthermore, at least one air inlet is provided on the left side of the housing, and a one-way valve is provided at the air inlet.

[0010] Furthermore, a solenoid valve is installed on the intake pipe.

[0011] Furthermore, both the first and second filtering mechanisms include a fixed frame, which is fixedly connected to the housing. A slot is provided in the middle of the fixed frame, and a movable frame is provided in the slot that can move up and down.

[0012] Furthermore, filter cotton is provided inside the movable frame of the first filtering mechanism.

[0013] Furthermore, a desiccant is provided inside the movable frame of the second filtration mechanism.

[0014] Furthermore, the bottom of the fixed frame is provided with multiple pin slots, and each pin slot contains a pin that can move up and down.

[0015] Furthermore, a spring is provided inside the pin, with the bottom of the spring fixedly connected to the bottom of the pin groove and the upper end of the spring fixedly connected to the top of the inner side of the pin.

[0016] Furthermore, the top of the box is equipped with an openable cover.

[0017] In use, when the second fan is turned on, its rotation causes the airflow to move to the left. The gas enters the housing through the grille and then passes through the first filter mechanism, which filters out dust and impurities using filter cotton. The gas then passes through the second filter mechanism, where a desiccant absorbs moisture, thus drying the gas. Finally, the gas enters the intake pipe to supply the oxygen generator.

[0018] When cleaning of the filter mechanism is required, the controller stops the second fan and closes the solenoid valve. Then, the first fan is restarted. The rotation of the first fan causes the airflow to move to the right. The suction force of the first fan opens the one-way valve, allowing air to enter the housing. The air then blows in the opposite direction towards the second and first filter mechanisms. This reverse airflow blows away a large amount of dust and impurities adhering to the first filter mechanism, expelling them from the grille and thus cleaning the filter mechanism to a certain extent. The large amount of dust adhering to the first filter mechanism over time can be effectively cleaned by the reverse airflow without affecting the airflow into the filter mechanism. Clean air can be supplied to the one-way valve position in the housing as needed, or a corresponding filter mechanism can be installed to prevent dust from entering the housing during reverse airflow. Supplying clean air to the one-way valve position is existing technology and is not technically limited; it can be configured as needed.

[0019] When it is necessary to replace or deeply clean the filter cotton and desiccant in the first and second filter mechanisms, the cover can be opened. After the cover is opened, the moving frame, under the elastic force of the spring, moves upward along the slot on the fixed frame via the pin. At this time, the pull groove above the moving frame is exposed above the fixed frame, and the moving frame can be easily pulled out through the pull groove. This allows for the replacement or cleaning of the filter cotton and desiccant.

[0020] Beneficial effects: This application supplies clean gas to the oxygen generator, which can filter and dry the gas; at the same time, it is equipped with a technical solution that can reverse the airflow to clean the filter cotton, so that the filter cotton can be cleaned as needed; and it is also equipped with a movable frame that can be easily disassembled, so that the filter cotton and desiccant can be easily replaced or cleaned.

[0029] Example 1, as Figure 1 As shown in Figure 6, the purpose of this utility model is achieved as follows: an oxygen generator gas filter includes a housing 1, a grille 2 is provided on the right side of the housing 1, an air inlet pipe 4 is provided on the left side of the housing 1, and a first filter mechanism and a second filter mechanism are provided inside the housing 1. The first filter mechanism filters impurities in the air, and the second filter mechanism dries the moisture in the gas.

[0030] A fan 10 is installed between the first and second filter mechanisms, and a second fan 8 is installed inside the housing 1 on the left side of the second filter mechanism. At least one air inlet is provided on the left side of the housing 1, and a one-way valve 5 is provided at the air inlet.

[0031] A solenoid valve 6 is installed on the air intake pipe 4. Both the first and second filter mechanisms include a fixed frame, which is fixedly connected to the housing 1. A slot is provided in the middle of the fixed frame, and a movable frame 9 is installed in the slot, which can move up and down. Filter cotton is installed in the movable frame 9 of the first filter mechanism. Desiccant is installed in the movable frame 9 of the second filter mechanism.

[0032] The bottom of the fixed frame has multiple pin slots, and each pin slot contains a pin 14 that can move up and down. A spring 11 is installed inside the pin 14. The bottom of the spring 11 is fixedly connected to the bottom of the pin slot, and the top of the spring 11 is fixedly connected to the top of the inner side of the pin 14. The top of the housing 1 is equipped with an openable cover plate 3.

[0033] In use, when the second fan 8 is turned on, the fan rotates, causing the airflow to move to the left. The gas enters the housing 1 through the grille 2, and then passes through the first filter mechanism, which filters out dust and impurities through filter cotton. The gas then passes through the second filter mechanism, where a desiccant absorbs moisture, thus drying the gas. The gas then enters the inlet pipe 4 to supply gas to the oxygen generator. The control of the fan and the solenoid valve 6 in this application are existing technologies and are not intended to limit the application; any implementation that achieves the required functions is acceptable.

[0034] When cleaning of the filter mechanism is required, the controller stops the second fan and closes the solenoid valve 6. Then, the first fan is restarted. The rotation of the first fan (10) moves the airflow to the right. The suction force of the first fan opens the one-way valve 5, allowing gas to enter the housing 1 through the one-way valve 5. The gas then blows in the opposite direction towards the second and first filter mechanisms. This reverse airflow blows away a large amount of dust and impurities adhering to the first filter mechanism, expelling them from the housing 1 through the grille 2, thus cleaning the filter mechanism to a certain extent. The large amount of dust adhering to the first filter mechanism over time can be effectively cleaned by the reverse airflow without affecting the airflow into the filter mechanism. Clean airflow can be supplied to the one-way valve 5 in the housing 1 as needed, or a corresponding filter mechanism can be installed to prevent dust from entering the housing 1 during reverse airflow. Supplying clean air to the one-way valve 5 is existing technology and is not subject to technical limitations; it can be configured as needed.

[0035] When it is necessary to replace or deeply clean the filter cotton and desiccant in the first and second filter mechanisms, the cover plate 3 can be opened. After the cover plate 3 is opened, the moving frame 9, under the elastic force of the spring 11, moves upward along the slot on the fixed frame via the pin 14. At this time, the pull groove 13 above the moving frame 9 is exposed above the fixed frame, and the moving frame 9 can be easily pulled out through the pull groove 13. This allows for the replacement or cleaning of the filter cotton and desiccant.
