Description

Technical Field

[0001] This utility model belongs to the technical field of air filter replacement mechanism, specifically a mechanism for quickly replacing the air filter of an oxygen generator. Background Technology

[0002] Oxygen generators are devices used to separate oxygen from the air and are widely used in medical, industrial, aerospace and other fields. Their core principle is to enrich oxygen from the air through physical or chemical methods. Common technologies include molecular sieve pressure swing adsorption, membrane separation and cryogenic distillation.

[0003] Oxygen generators require air filters to be used when drawing in air through a compressor. These air filters are usually fixed inside the oxygen generator as a core component, which makes it difficult for staff to disassemble and replace them, thus affecting their use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a mechanism for quickly replacing the air filter of an oxygen generator, which solves the problem that air filters are usually fixed inside the oxygen generator as one of the core components, which makes it difficult for staff to disassemble and replace them, thus affecting their use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanism for quickly replacing the air filter of an oxygen generator, comprising an oxygen generator body, two connecting chambers fixedly installed on the oxygen generator body, an air outlet pipe connected to the bottom of the connecting chamber, an air inlet pipe connected to one side of the connecting chamber, an air filter disposed inside the connecting chamber, a cover installed on the top of the connecting chamber, a connecting end connected to the air filter, multiple convex holes formed on the connecting end, and a handle connected to the top of the cover;

[0006] A spring is connected to the bottom of the cover, and a threaded sleeve is connected to the cover via the spring. A rotating rod is rotatably connected inside the cover. One end of the rotating rod passes through the cover and is connected to a handwheel. A main gear is connected to the rotating rod, and multiple secondary gears are meshed on the main gear. An insert rod is connected to the secondary gear, and one end of the insert rod passes through the cover and is connected to a protrusion.

[0007] As a further embodiment of this utility model: the shape of one end of the plug connecting protrusion is the same as the overall shape of the convex hole, and one end of the plug is inserted into the convex hole, and the gas outlet pipe is connected to the oxygen generating equipment body.

[0008] As a further embodiment of this utility model: a plurality of first blocks and a plurality of second blocks are connected below the connecting end, the positions of the first blocks and the second blocks correspond to the positions of the convex holes, and the first blocks are disposed on one side of the convex portion of the convex hole, and the directions of the second blocks and the first blocks are perpendicular to each other.

[0009] As a further embodiment of this utility model: the cover has a cavity design, and both the main gear and the auxiliary gear are located inside the cover. There are four auxiliary gears in total, and the four auxiliary gears are arranged in a centrally symmetrical manner.

[0010] As a further embodiment of this utility model: a rotating ring is rotatably connected above the threaded sleeve, and the rotating ring is connected to the spring. The rotating ring is designed in an I-shape and is fitted with the threaded sleeve. The outer wall of the connecting chamber is provided with threads that are threadedly engaged with the threaded sleeve.

[0011] As a further embodiment of this utility model: a damping sleeve is provided at the contact point between the rotating rod and the cover, and the damping sleeve is sleeved on the rotating rod and fixedly connected to the cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This quick-change mechanism for the air filter of an oxygen generator consists of a handwheel, a rotating rod, a main gear, a secondary gear, an insert rod, a protrusion, a convex hole, a first stop, and a second stop. After inserting the insert rod into the convex hole, turning the handwheel rotates the rotating rod, causing the main gear to synchronously drive multiple secondary gears to rotate. This causes the secondary gears to drive the insert rod to rotate. At this time, the protrusion at one end of the insert rod will misalign with the convex hole and abut against the second stop, thus connecting the air filter's connection end to the cover. This allows the air filter to be pulled out together when the cover is removed. To separate the filter, simply rotate the main gear in the opposite direction, causing the protrusion to contact the first stop. The insert rod can then be pulled out of the convex hole, completing the separation. No operation inside the oxygen generator body is required, making it convenient for staff to disassemble and replace the filter.

[0014] This quick-change air filter replacement mechanism for oxygen generators uses a connecting chamber, threaded sleeve, rotating ring, and spring. When the cover is inserted into the connecting chamber port, the operator pulls down the threaded sleeve to make it contact the threads on the outer wall of the connecting chamber. Then, by turning the threaded sleeve, the rotating ring is held in place by the spring, allowing the threaded sleeve to connect with the threads of the connecting chamber. Compared to fixing with bolts and screws, this reduces the number of turning operations, simplifies the process, and improves disassembly and assembly efficiency. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a mechanism for quickly replacing the air filter of an oxygen generator, including an oxygen generator body 1, two connecting chambers 2 fixedly installed on the oxygen generator body 1, an air outlet pipe 3 connected to the bottom of the connecting chamber 2, an air inlet pipe 4 connected to one side of the connecting chamber 2, an air filter 5 installed inside the connecting chamber 2, and a cover 6 installed on the top of the connecting chamber 2. The cover 6 has a cavity design, and the main gear 14 and the auxiliary gear 15 are both located inside the cover 6. There are four auxiliary gears 15 in total, and the four auxiliary gears 15 are arranged in a centrally symmetrical manner. Through the meshing of the main gear 14 and the multiple auxiliary gears 15, the operator can synchronously control the rotation of multiple insertion rods 16, while the cover 6 can protect the main gear 14 and the auxiliary gears 15, reducing contact with the outside world.

[0023] The air filter 5 is connected to a connecting end 7, and below the connecting end 7 are multiple first stops 18 and multiple second stops 19. The positions of the first stops 18 and the second stops 19 correspond to the positions of the convex holes 8. The first stops 18 are located on one side of the convex part of the convex hole 8, and the second stops 19 are perpendicular to the first stops 18. By having a protrusion 17 at one end of the insertion rod 16 abut against the first stops 18 and the second stops 19 respectively, it is easy for the staff to determine whether the end of the insertion rod 16 connected to the protrusion 17 coincides with or is misaligned with the convex hole 8, thereby facilitating the removal or locking of the insertion rod 16.

[0024] Multiple convex holes 8 are provided on the connecting end 7. A handle 9 is connected to the top of the cover 6, and a spring 10 is connected to the bottom of the cover 6. The cover 6 is connected to a threaded sleeve 11 through the spring 10. A rotating ring 20 is rotatably connected to the top of the threaded sleeve 11 and is connected to the spring 10. The rotating ring 20 is designed in an I-shape and fits into the threaded sleeve 11. The outer wall of the connecting chamber 2 is provided with threads that are threaded into the threaded sleeve 11. Through the I-shaped design of the rotating ring 20, the rotating ring 20 can be axially limited while rotating on the threaded sleeve 11 to prevent the rotating ring 20 from disengaging from the threaded sleeve 11.

[0025] A rotating rod 12 is rotatably connected inside the cover 6. One end of the rotating rod 12 passes through the cover 6 and is connected to a handwheel 13. A damping sleeve 21 is provided at the contact point between the rotating rod 12 and the cover 6. The damping sleeve 21 is sleeved on the rotating rod 12 and fixedly connected to the cover 6. The damping sleeve 21 increases the friction with the rotating rod 12, thereby preventing the rotating rod 12 from rotating accidentally when no force is applied.

[0026] A main gear 14 is connected to the rotating rod 12. Multiple secondary gears 15 are meshed on the main gear 14. A plug rod 16 is connected to the secondary gear 15. One end of the plug rod 16 passes through the cover 6 and is connected to a protrusion 17. The shape of the end of the plug rod 16 connected to the protrusion 17 is the same as the overall shape of the convex hole 8. The end of the plug rod 16 is inserted into the convex hole 8. The air outlet pipe 3 is connected to the oxygen generator body 1. Through the protrusion 17 at one end of the plug rod 16, it can be misaligned with the convex hole 8 and contact the bottom of the connecting end 7 when the plug rod 16 rotates, thereby connecting the cover 6 and the connecting end 7 together. This allows the staff to remove the air filter 5 by pulling the cover 6 without having to reach in and pull out the air filter 5.

[0027] The working principle of this utility model is as follows:

[0028] During installation, the insert rod 16 is inserted into the convex hole 8. Then, the handwheel 13 is used to rotate the rotating rod 12, causing the main gear 14 to synchronously drive multiple auxiliary gears 15 to rotate. This causes the auxiliary gears 15 to drive the insert rod 16 to rotate. At this time, the protrusion 17 at one end of the insert rod 16 will be misaligned with the convex hole 8 and abut against the second stop 19, thereby connecting the connecting end 7 of the air filter 5 to the cover 6. Then, the air filter 5 and the cover 6 are pushed into the connecting chamber 2 together. At this time, by pulling down the threaded sleeve 11, the threaded sleeve 11 is made to engage with the outer wall of the connecting chamber 2. After the threaded part contacts, the operator screws the threaded sleeve 11 so that it can be threadedly connected to the connecting chamber 2, thus completing the fixation. When disassembling, the operator reverses the screwed sleeve 11 to disengage it from the threaded part of the connecting chamber 2, and the spring 10 will rebound and pull the threaded sleeve 11 upward. At this time, the air filter 5 can be pulled out by pulling the cover 6. Then, the main gear 14 is rotated in the opposite direction so that the protrusion 17 contacts the first stop 18. At this time, the insertion rod 16 can be pulled out from the convex hole 8, thus completing the separation work.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
