Description

Technical Field

[0001] This utility model belongs to the field of oxygen generator technology, and in particular relates to a molecular sieve fixing structure for an oxygen generator. Background Technology

[0002] An oxygen concentrator is a device that separates oxygen from the air using physical or chemical methods to provide high-concentration or oxygen-enriched air. The molecular sieve in an oxygen concentrator is the core component that enables oxygen separation. Its function is to extract high-purity oxygen from the air by utilizing the adsorption properties of the molecular sieve. The molecular sieve in an oxygen concentrator is usually a cylindrical metal or engineering plastic container filled with a large number of molecular sieve particles (such as zeolite molecular sieves). It has air inlet and outlet and gas distribution devices at both ends to ensure that the air passes through the molecular sieve layer evenly.

[0003] Most molecular sieves in oxygen concentrators are cylindrical and are typically installed on a mounting base inside the machine. This mounting base usually has a groove that fits the molecular sieve, securing it in place. However, during use, the oxygen concentrator may be subjected to impacts, causing the molecular sieve to detach from the groove. Therefore, a molecular sieve fixing structure is needed to secure the molecular sieve within the oxygen concentrator, preventing it from detaching and ensuring its stability. Utility Model Content

[0004] The purpose of this invention is to provide a molecular sieve fixing structure for an oxygen generator, which can fix the molecular sieve through a clamping structure, preventing the molecular sieve from detaching inside the oxygen generator and ensuring the firmness of the molecular sieve inside the oxygen generator, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A molecular sieve fixing structure for an oxygen generator includes a fixing base disposed in the inner cavity of the oxygen generator body. The top of the fixing base is provided with two symmetrical tanks. The top of the fixing base has two symmetrical positioning grooves. The bottom of the tanks is adapted to the positioning grooves. Limiting strips are fixedly connected to the opposite sides of the two tanks. The side of the limiting strip away from the tank has a slot. Limiting block one is fixedly connected to the top of the fixing base. Fixing plates are fixedly connected to the front and back of the fixing base. The top of the fixing plate has a limiting groove. The slot is adapted to the limiting groove. A sleeve is fixedly connected to the side of the fixing plate away from the tank. A locking rod is slidably connected to the inner cavity of the sleeve. The locking rod is adapted to the locking groove. Limiting block two is fixedly connected to the side of the fixing plate away from the tank.

[0006] Preferably, anti-slip pads are fixedly connected to both the front and back of the limiting block one, and the side of the anti-slip pad closest to the tank body is curved.

[0007] Preferably, a power supply is provided at the bottom of the oxygen generator body, the positioning groove is elliptical, and the limiting strip is strip-shaped.

[0008] Preferably, the slot is a rectangular slot, the slot is located between the limiting block two and the sleeve, and the locking rod is L-shaped.

[0009] Preferably, the second limiting block is rectangular, and the anti-slip pad has anti-slip patterns on the side closest to the tank.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model places two symmetrical tanks in the inner cavity of the positioning groove. At this time, the limiting strip will enter the inner cavity of the limiting groove. The locking rod is moved so that the locking rod passes through the locking groove and fits against the limiting block. At this time, the locking rod will limit the tank through the locking groove and the limiting strip. This can achieve the goal of fixing the molecular sieve through the locking structure, preventing the molecular sieve from detaching inside the oxygen generator and ensuring the firmness of the molecular sieve inside the oxygen generator.

[0012] 2. By setting an anti-slip pad, the anti-slip pad will fit against the can when the can is placed in the inner cavity of the positioning groove, increasing the friction between the limiting block and the can, preventing the can from shaking in the inner cavity of the positioning groove, and improving the stability of the can in the inner cavity of the positioning groove.

Anti-slip pads 13 are fixedly connected to both the front and back of the limiting block 7, with the anti-slip pads 13 close to the canisters. One side of the can 3 is curved. With the anti-slip pad 13, when the can 3 is placed in the inner cavity of the positioning groove 4, the anti-slip pad 13 will fit against the can 3, increasing the friction between the limiting block 1 7 and the can 3, preventing the can 3 from shaking in the inner cavity of the positioning groove 4, and improving the firmness of the can 3 in the inner cavity of the positioning groove 4. The front and back of the fixed base 2 are fixedly connected to the fixed plate 8. The top of the fixed plate 8 starts with the limiting groove 9. The slot 6 is adapted to the limiting groove 9. The side of the fixed plate 8 away from the can 3 is fixedly connected to the sleeve 10. The inner cavity of the sleeve 10 is slidably connected to the locking rod 11. The locking rod 11 is adapted to the locking groove 6. The side of the fixed plate 8 away from the can 3 is fixedly connected to the limiting block 2 12.

[0023] Example 2:

[0024] Figure 1-4 This invention illustrates a molecular sieve fixing structure for an oxygen concentrator according to an embodiment of the present invention. It includes a fixing base 2 disposed within the inner cavity of the oxygen concentrator body 1. Two symmetrical canisters 3 are disposed on the top of the fixing base 2. Two symmetrical positioning grooves 4 are located at the top of the fixing base 2. The bottom of each canister 3 is fitted into the positioning grooves 4. Limiting strips 5 are fixedly connected to opposite sides of each canister 3. A slot 6, rectangular in shape, is formed on the side of the limiting strip 5 away from the canister 3. The slot 6 is located between the limiting block 12 and the sleeve 10. The locking rod 11 is L-shaped. The fixed base 2 has a limiting block 7 fixedly connected to its top. The fixed base 2 has a fixed plate 8 fixedly connected to both its front and back sides. The fixed plate 8 has a limiting groove 9 at its top. The slot 6 is adapted to the limiting groove 9. A sleeve 10 is fixedly connected to the side of the fixed plate 8 away from the tank 3. A locking rod 11 is slidably connected to the inner cavity of the sleeve 10.

The anti-slip pad 13 has anti-slip texture on the side near the tank 3.

[0025] Working principle: When using this utility model, the user places two symmetrical canisters 3 into the inner cavities of the two positioning slots 4 respectively. At this time, the limiting strip 5 will enter the inner cavity of the limiting slot 9. By moving the locking rod 11, the locking rod 11 passes through the slot 6 and is in contact with the limiting block 12. The locking rod 11 can limit the canister 3 through the limiting strip 5 and the slot 6, preventing the molecular sieve from detaching inside the oxygen generator and ensuring the firmness of the molecular sieve inside the oxygen generator. With the setting of the anti-slip pad 13, when the canister 3 is placed in the inner cavity of the positioning slot 4, the anti-slip pad 13 will be in contact with the canister 3, increasing the friction between the limiting block 7 and the canister 3, preventing the canister 3 from shaking in the inner cavity of the positioning slot 4, and improving the firmness of the canister 3 in the inner cavity of the positioning slot 4.

[0026] In summary, the molecular sieve fixing structure of this oxygen concentrator, by placing two symmetrical tanks 3 in the inner cavity of the positioning groove 4, allows the limiting strip 5 to enter the inner cavity of the limiting groove 9. Moving the locking rod 11 causes it to pass through the locking groove 6 and abut against the limiting block 12. The locking rod 11 then limits the tanks 3 through the locking groove 6 and the limiting strip 5, thus fixing the molecular sieve and preventing it from detaching inside the oxygen concentrator, ensuring its stability within the oxygen concentrator.
