Description

Technical Field

[0001] This utility model relates to the field of molecular sieve oxygen generator technology, specifically a molecular sieve oxygen generator with a dehumidification structure. Background Technology

[0002] Molecular sieve oxygen generators are common medical devices in hospitals. They can be used to produce oxygen at a certain concentration. When using molecular sieve oxygen generators, the air must not contain moisture when it is introduced, so a gas-water separator is used to dry the air.

[0003] Patent CN221107394U discloses a gas-liquid separator for a molecular sieve oxygen generator. By incorporating an airflow slowing structure, a pneumatic rotating component, and a pushing component, the separator achieves several improvements. First, the airflow slowing structure reduces gas flow rate, improving gas-liquid separation. Second, the pneumatic rotating component generates centrifugal force, further enhancing separation. Third, the cooperation between the pushing rod and the pushing block allows the inner shell to reciprocate, shaking off accumulated liquid from its inner wall. This effectively prevents water droplets from condensing inside the shell and failing to fall immediately, thus preventing them from re-recombining with the gas and ensuring efficient and effective dehumidification.

[0004] However, the airflow path in the above-mentioned steam-water separator is relatively short, and the dehumidification method is simple, relying only on centrifugation and shaking for primary dehumidification. In high humidity environments, dehumidification may be incomplete. If dehumidification is incomplete, residual water vapor may still enter the molecular sieve, affecting its lifespan and adsorption efficiency.

[0005] Based on this, a molecular sieve oxygen generator with a dehumidification structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a molecular sieve oxygen generator with a dehumidification structure to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A molecular sieve oxygen generator with a dehumidification structure includes an oxygen generator body, a molecular sieve module for separating oxygen within the oxygen generator body, a dehumidification mechanism for drying air on one side of the molecular sieve module, a centrifugal dehumidification chamber within the dehumidification mechanism, a condenser seat above the centrifugal dehumidification chamber, and an air drying filter element above the condenser seat.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the oxygen generator body has a support base at the lower end, a display screen at the upper end, a placement seat on one side, and an air outlet above the placement seat.

[0009] In one alternative: the dehumidification mechanism adopts a cylindrical structure, the lower end of the dehumidification mechanism is provided with an air inlet pipe, the bottom of the dehumidification mechanism is provided with a drain pipe with a valve, the top of the dehumidification mechanism is provided with a sealing plate, and the upper end of the sealing plate is provided with an air outlet pipe.

[0010] In one alternative: the sealing plate is bolted to the dehumidification mechanism, and the air outlet pipe is connected to the air inlet of the molecular sieve module.

[0011] In one alternative: the centrifugal dehumidification chamber has an air inlet connected to the air inlet pipe on one side, the air inlet being tangential to the centrifugal dehumidification chamber, and a liquid collection hopper at the bottom of the centrifugal dehumidification chamber, the bottom of the liquid collection hopper being connected to the drain pipe.

[0012] In one alternative: the condenser housing has multiple serpentine pipes inside, and the condenser housing has cooling fins on its side.

[0013] In one alternative: the condenser base is made of stainless steel.

[0014] In one alternative: the air drying filter element uses a filter element with a precision of 3μm to 1μm.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a three-stage dehumidification mechanism consisting of a tangentially inlet centrifugal dehumidification chamber, a combination of a serpentine pipe and a cooling plate in the condenser seat, and an air drying filter. This effectively removes droplets and water vapor from the air, ensuring that the air entering the molecular sieve module is dry and clean, extending the service life of the molecular sieve and improving the oxygen purity.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, a molecular sieve oxygen generator with a dehumidification structure includes an oxygen generator body 100, a support base 101 at the lower end of the oxygen generator body 100, a display screen 102 at the upper end of the oxygen generator body 100, a placement seat 103 on one side of the oxygen generator body 100, an air outlet 104 above the placement seat 103, a molecular sieve module 200 for separating oxygen generation inside the oxygen generator body 100, a dehumidification mechanism 300 for drying air on one side of the molecular sieve module 200, a centrifugal dehumidification chamber 400 inside the dehumidification mechanism 300, a condenser seat 500 above the centrifugal dehumidification chamber 400, and an air drying filter element 600 above the condenser seat 500. The air drying filter element 600 uses a filter element with a precision of 3μm to 1μm. In use, the air is dehumidified in three stages through the centrifugal dehumidification chamber 400, the condenser seat 500, and the air drying filter element 600 to ensure that the air entering the molecular sieve module is dry and clean.

[0023] In one embodiment, such as Figure 3 As shown, the dehumidification mechanism 300 adopts a cylindrical structure. The lower end of the dehumidification mechanism 300 is provided with an air inlet pipe 301, the bottom of the dehumidification mechanism 300 is provided with a drain pipe 304 with a valve, the top of the dehumidification mechanism 300 is provided with a sealing plate 302, the upper end of the sealing plate 302 is provided with an air outlet pipe 303, the sealing plate 302 is bolted to the dehumidification mechanism 300, and the air outlet pipe 303 is connected to the air inlet of the molecular sieve module 200. In use, air enters the dehumidification mechanism 300 through the air inlet pipe 301, and the air is dehumidified in three stages through the centrifugal dehumidification chamber 400, the condenser seat 500 and the air drying filter 600 in the dehumidification mechanism 300. The liquid droplets in the air are discharged through the drain pipe 304, and the dried air enters the molecular sieve module 200 through the air outlet pipe 303.

[0024] In one embodiment, such as Figure 4As shown, a gas inlet 401 connected to the air inlet pipe 301 is provided on one side of the centrifugal dehumidification chamber 400. The gas inlet 401 is tangentially arranged with the centrifugal dehumidification chamber 400. A liquid collection hopper 402 is provided at the lower part of the centrifugal dehumidification chamber 400. The bottom of the liquid collection hopper 402 is connected to the drain pipe 304. When in use, when air enters the centrifugal dehumidification chamber 400 tangentially through the gas inlet 401, the humid air rotates at high speed to generate centrifugal force, which throws large-diameter water droplets directly onto the wall and falls into the liquid collection hopper 402.

[0025] In one embodiment, such as Figure 4 As shown, the condenser seat 500 is equipped with multiple serpentine pipes 501, and cooling plates are provided on the side of the condenser seat 500. The condenser seat 500 is made of stainless steel. In use, the cooling plates cool the condenser seat 500, so that when the air passes through the serpentine pipes 501, the tiny water vapor in the air condenses and precipitates out.

[0026] The above embodiment discloses a molecular sieve oxygen generator with a dehumidification structure. In use, air enters the dehumidification mechanism 300 through the air inlet pipe 301, and first enters the centrifugal dehumidification chamber 400 tangentially through the air outlet 401, causing the humid air to rotate at high speed and generate centrifugal force, which throws large-diameter water droplets directly onto the wall and falls into the liquid collection hopper 402. Then, through the serpentine pipe 501, the tiny water vapor in the air is condensed and precipitated. Next, it is further dried through the air drying filter element 600. The dried air enters the molecular sieve module 200 through the air outlet pipe 303.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
