Technical Field

[0001] The utility model relates to the technical field of oxygen generators, and particularly relates to a small molecular sieve oxygen generator. Background Art

[0002] An oxygen generator is a kind of machine for producing oxygen. Its principle is to use air separation technology. First, air is compressed at high density and then the components in the air are separated into gas and liquid at a certain temperature by using the different condensation points of each component in the air. Then, rectification is carried out to separate it into oxygen and nitrogen. Generally, since it is mostly used for producing oxygen, people are used to calling it an oxygen generator. In the oxygen generator, in order to ensure the purity of oxygen, a molecular sieve device is used to purify the air.

[0003] However, when the existing molecular sieve device installs the filter cartridge and the air outlet pipe, gas leakage in the filter cartridge may occur during the interface connection, and the installation process is cumbersome, increasing the installation time. Excessive gas leakage time may affect the use of patients. To solve this technical problem, the utility model provides a small molecular sieve oxygen generator. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a small molecular sieve oxygen generator, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A small molecular sieve oxygen generator includes a bottom plate. The upper surface of the bottom plate is connected with a box body. A filter cartridge is arranged inside the box body. One end of the filter cartridge is fixedly communicated with an outlet end. A first fixing plate is connected to the inner wall of the outlet end.

A first telescopic rod is connected to the outer surface of the first fixing plate. One end of the first telescopic rod is connected with the outer surface of the first conical interface. A first spring is sleeved on the outer surface of the first telescopic rod. One end of the first spring is connected with the outer surface of the first fixing plate, and the other end of the first spring is connected with the outer surface of the first conical interface. An interface end is arranged on one side of the outlet end.

[0007] Preferably, a second fixing plate is connected to the inner wall of the interface end. A second sliding rod is slidably connected inside the second fixing plate. One end of the second sliding rod is connected with a second conical interface. A second telescopic rod is connected to the outer surface of the second fixing plate.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a small molecular sieve oxygen generator includes a base plate 1. The upper surface of the base plate 1 is connected with a box body 2. A filter cylinder 3 is arranged inside the box body 2. One end of the filter cylinder 3 is fixedly communicated with a suction disc 20. An air inlet hole 21 is opened on the outer surface of the box body 2. A blower is arranged in the suction disc 20 for air extraction, and the gas enters from the air inlet hole 21.

[0024] One end of the filter cylinder 3 is fixedly communicated with an outlet end 4. The upper surface of the base plate 1 is connected with a placing rack 22. The upper surface of the placing rack 22 is connected with the bottom surface of the filter cylinder 3. The filter cylinder 3 can effectively remove impurities and harmful substances in the oxygen, ensuring that the output oxygen reaches the purity of medical grade. The inner wall of the outlet end 4 is connected with a first fixing plate 5. A first sliding rod 6 is slidably connected inside the first fixing plate 5. One end of the first sliding rod 6 is connected with a first conical interface 7. The first conical interface 7 is in contact with the outlet end 4 to seal the outlet end 4 and prevent gas leakage.

[0025] The outer surface of the first fixing plate 5 is connected with two first telescopic rods 8, which are symmetrically distributed on both sides of the first sliding rod 6. One end of the first telescopic rod 8 is connected with the outer surface of the first conical interface 7. A first spring 9 is sleeved on the outer surface of the first telescopic rod 8. One end of the first spring 9 is connected with the outer surface of the first fixing plate 5, and the other end of the first spring 9 is connected with the outer surface of the first conical interface 7.

[0026] One side of the outlet end 4 is provided with an interface end 10. There are two first springs 9, which are symmetrically distributed inside the outlet end 4. When it is necessary to separate the outlet end 4 from the interface end 10, at the moment when the outlet end 4 and the interface end 10 are separated, the first spring 9 resets and tightly contacts the first conical interface 7 with the outlet end 4 again to prevent gas leakage. The diameters of the outlet end 4 and the interface end 10 are the same, and gas can flow when the outlet end 4 is in contact with the interface end 10.

[0027] The inner wall of the interface end 10 is connected with a second fixing plate 11. A second sliding rod 12 is slidably connected inside the second fixing plate 11. One end of the second sliding rod 12 is connected with a second conical interface 13. The outer surface of the second fixing plate 11 is connected with a second telescopic rod 14. One end of the second telescopic rod 14 is connected with the outer surface of the second conical interface 13. A second spring 15 is sleeved on the outer surface of the second telescopic rod 14. One end of the second spring 15 is connected with the outer surface of the second fixing plate 11, and the other end of the second spring 15 is connected with the outer surface of the second conical interface 13. When the outlet end 4 is in contact with the interface end 10, the second spring 15 is compressed, the second telescopic rod 14 is shortened, and the second conical interface 13 is no longer in contact with the interface end 10.

[0028] The upper surface of the interface end 10 is connected with a clamping pipe 16. An inlaid circle 17 is formed on the inner wall of the clamping pipe 16. A rubber round head 18 is connected to the outer surface of the outlet end 4. The rubber round head 18 is finally clamped in the inlaid circle 17 to connect the interface end 10 and the outlet end 4. A through column 19 is formed on the inner wall of the inlaid circle 17. The through columns 19 are evenly distributed on the inner wall of the interface end 10. When the outlet end 4 is in contact with the interface end 10, the clamping pipe 16 slides on the outer surface of the outlet end 4, and the rubber round head 18 enters the inlaid circle 17 along the through column 19 on the inner wall of the clamping pipe 16.

[0029] It should be noted that during the actual use of the device, when installing the outlet end 4 and the interface end 10 together, press the first conical interface 7 against the second conical interface 13 until it reaches the position where the outlet end 4 is in contact with the interface end 10. At this time, the first spring 9 and the second spring 15 are compressed, the first telescopic rod 8 and the second telescopic rod 14 are shortened, the first conical interface 7 will not be in contact with the outlet end 4, and the second conical interface 13 will not be in contact with the interface end 10. A channel is formed between the interface end 10 and the outlet end 4, allowing gas to flow. When the outlet end 4 is in contact with the interface end 10, the clamping pipe 16 slides on the outer surface of the outlet end 4, and the rubber round head 18 enters the inlaid circle 17 along the through column 19 on the inner wall of the clamping pipe 16 to fix the outlet end 4 and the interface end 10 together. The suction disc 20 can suck air and send the gas into the filter cylinder 3 for treatment.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
