Description

Technical Field

[0001] The invention belongs to the technical field of boosters, and in particular relates to a booster device for a medical oxygen generator. Background Art

[0002] The oxygen generator booster is a device used to increase the pressure of oxygen or air. It compresses the inhaled oxygen or air through the internal compression mechanism to increase its pressure to meet specific usage requirements. In the oxygen production process, the main function of the booster is to increase the pressure of air or oxygen entering the oxygen generator, thereby ensuring the smooth progress of the oxygen production process. The device is widely used in various occasions that require high-pressure oxygen, such as medical, industrial, welding, cutting and other fields.

[0003] The patent with application number 202310973515.9 discloses an oxygen booster device for a medical oxygen concentrator. The application sets an oxygen storage mechanism and a booster mechanism. The user can fix the transmission pipe to the top of the air inlet pipe by a third fixing screw, and the air inlet pipe can be fixed to the mounting block by a second fixing screw, thereby completing the assembly of the device. By starting the second drive motor, the second drive motor drives the transmission belt to operate, the transmission belt drives the rotating shaft to operate, the rotating shaft drives the supercharger to operate, the supercharger collects oxygen through the air inlet pipe, and pressurizes the air in the air through the transmission pipe. The oxygen is filtered and transmitted to the booster, so that the device can boost oxygen. By setting an oxygen inlet connected to the transmission port, the oxygen inlet transmits the oxygen to the oxygen storage tank, thereby ensuring the applicability of the device.

[0028] Embodiment 1

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention provides a technical solution: a booster device for a medical oxygen concentrator, which uses a compressor to convert low-pressure oxygen or air into high-pressure oxygen or air. When the compressor inhales low-pressure oxygen or air, the pressure of the oxygen or air is increased to a required pressure level through the compression action of the compressor, and then the high-pressure oxygen or air is delivered to the required application scenario, including a gas storage tank 100, a driving motor 104 is installed on the top of the gas storage tank 100, a booster 105 is installed on one side of the driving motor 104, the gas storage tank 100 is used to store the gas pressurized by the booster 105, and a filter component; the filter component is arranged on the top front surface of the gas storage tank 100, and one end of the filter component An air inlet pipe 109 is provided, and the filter assembly includes a filter box 200. A dual-channel air inlet structure is provided on the inner side of the filter box 200. A mounting plate 202 is provided at the bottom of the filter box 200, and a molecular filter sieve 203 for filtering is installed on the mounting plate 202. When the booster device in the application is used for work, the gas enters from the booster 105 and is compressed and passed into the filter box 200. After the gas enters, it passes through the vent hole 208 opened on the partition 207, and then is filtered by the molecular filter sieve 203 installed at the inner bottom of the filter box 200. The filtered gas diffuses and passes through the air inlet groove 206 and the air inlet pipe 109, and then the compressed gas enters the gas storage tank 100 for storage.

[0030] Specifically, an inner tube 205 is fixedly installed on the inner side of the filter box 200, and an integrated partition 207 is installed on both sides of the inner tube 205. At the same time, an integrated vertical partition 2 is set at the bottom of the inner tube 205. The inner tube 205, the partition 207 and the partition 2 divide the inner side of the filter box 200 into a double-channel structure, and both sides can be used at the same time or one side can be used. The bottom of the inner tube 205 is symmetrically provided with air inlet grooves 206, and the partition 2 separates the symmetrical air inlet grooves 206, so that both channels can be connected. The partition 207 is provided with a vent hole 208, and the vent hole 208 is provided with a vent hole 208. 08 and is located on the upper surface of the partition 207. A sliding guide groove 209 is provided. Threaded rods 210 are installed at both ends of the inner top of the filter box 200. One end of the threaded rod 210 is located on the outer side of the filter box 200 and is provided with a knob 211. The knob 211 is used to drive the threaded rod 210 to rotate. A threaded seat 212 is also installed on the threaded rod 210. A sliding blocking block 213 is provided at the bottom of the threaded seat 212. The sliding blocking block 213 is arranged in the sliding guide groove 209 for sliding limit. At the same time, the vent hole 208 is also blocked and closed by the sliding blocking block 213. After the device has been used for a period of time, if the filtering performance of the molecular filter sieve 203 decreases and needs to be replaced, the bolts 204 at both ends of the mounting plate 202 can be directly unscrewed, and then the molecular filter sieve 203 can be taken out for replacement. At the same time, during the replacement process, in order to avoid the channel on one side of the molecular filter sieve 203 not being sealed when replaced, resulting in compressed gas leaking from the filter tank 201, the knob 211 on the side of the corresponding channel can be adjusted during replacement. When adjusting, the knob 211 is manually turned, and the knob 211 drives the threaded rod 210 at the corresponding position on the inner side of the filter box 200 to rotate. When the threaded rod 210 rotates, The threaded seat 212 is driven to move by the thread, and when the threaded seat 212 moves, it drives the sliding sealing block 213 to slide in the sliding guide groove 209 set on the top of the partition 207. When the sliding sealing block 213 moves to one end of the sliding guide groove 209, the vent 208 is blocked by the sliding blocking block 213, thereby blocking the vent 208 on one side of the corresponding channel to avoid gas leakage during the replacement process. At the same time, the device does not need to be shut down during the replacement process, and only the channel on one side needs to be closed. While improving the working efficiency of the device, it also ensures the practicality and functionality of the device.
