Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, and in particular relates to an oxygen concentrator with a pressure regulating function. Background Art

[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature. Then, it is distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen generator.

[0003] When using an oxygen concentrator, a humidifying mechanism is set up to prevent the oxygen inhaled into the body from being too dry. When the user lowers the pressure of the valve body, the oxygen pressure before the valve body will increase, which will cause the pressure inside the humidifying mechanism to increase. If the pressure in the humidifying mechanism cannot be adjusted in time, when the pressure is too high, it will easily cause certain damage to the humidifying mechanism, thereby reducing the stability and safety of the user during use. Utility Model Content

[0004] The purpose of the utility model is to provide an oxygen concentrator with a simple structure and reasonable design and a pressure regulating function in order to solve the above problems.

[0008] As a further optimization solution of the utility model, the exterior of the water storage cylinder is provided with an external thread, and the inner wall of the sealing cover is provided with an internal thread used in conjunction with the external thread.

[0009] As a further optimization scheme of the utility model, the oxygen supply mechanism includes a connecting pipe installed on the inner wall of the top of the sealing cover and connected to the oxygen inlet pipe, an air outlet tube installed at the bottom of the connecting pipe, and multiple air outlets opened at the bottom of the air outlet tube.

[0010] As a further optimization solution of the utility model, an oxygen outlet pipe is installed on the top of the sealing cover, and a pressure regulating valve is installed outside the oxygen outlet pipe.

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] like Figure 1 - Figure 3As shown, an oxygen concentrator with a pressure regulating function comprises an oxygen concentrator body 1, and a sealing cover 2 installed on one side of the oxygen concentrator body 1 through a fixing mechanism, an oxygen outlet pipe 5 is installed on the top of the sealing cover 2, and a pressure regulating valve 6 is installed on the outside of the oxygen outlet pipe 5, the fixing mechanism comprises a fixing ring 14 installed on one side of the oxygen concentrator body 1, the sealing cover 2 is fixed inside the fixing ring 14, a water storage cylinder 9 is threadedly connected to the bottom of the sealing cover 2, an external thread is arranged on the outside of the water storage cylinder 9, and an internal thread used in conjunction with the external thread is arranged on the inner wall of the sealing cover 2. When the pure water in the water storage cylinder 9 is used up, the water storage cylinder 9 can be directly unscrewed from the sealing cover 2 for convenient water filling, an oxygen inlet pipe 3 connected with the sealing cover 2 is installed at the oxygen outlet of the oxygen concentrator body 1, an oxygen supply mechanism for supplying oxygen to the pure water in the water storage cylinder 9 is installed inside the sealing cover 2, the oxygen supply mechanism comprises a connecting pipe 7 installed on the inner wall of the top of the sealing cover 2 and connected with the oxygen inlet pipe 3, and a connecting pipe 7 is installed on the inner wall of the top of the sealing cover 2 and connected with the oxygen inlet pipe 3. At the air outlet tube 8 at the bottom of the connecting tube 7, and multiple air outlets opened at the bottom of the air outlet tube 8, when the oxygen generator body 1 is started, oxygen will enter the interior of the connecting tube 7 from the oxygen inlet tube 3, and the oxygen entering the connecting tube 7 will enter the pure water in the water storage tube 9 through the multiple air outlets opened at the bottom of the air outlet tube 8. At this time, the oxygen will be discharged through the oxygen outlet tube 5. The oxygen passes through the pure water to increase the humidity in the oxygen, so that the patient's trachea remains moistened, which improves the safety of use. A pressure regulating mechanism for regulating the pressure in the water storage tube 9 is installed on the top of the sealing cover 2. The pressure regulating mechanism includes a pressure regulating tube 4 installed on the top of the sealing cover 2, a sealing tube 11 sleeved inside the pressure regulating tube 4, a spring 10 installed on the top of the sealing tube 11, a first pressure regulating port 12 opened outside the pressure regulating tube 4, and a second pressure regulating port 13 opened outside the sealing tube 11 and used in conjunction with the first pressure regulating port 12. The top of the spring 10 is fixedly connected to the top inner wall of the pressure regulating tube 4.

[0019] It should be noted that, when the user lowers the pressure of the regulating valve 6 during use, the oxygen pressure before the pressure regulating valve 6 will increase, and the oxygen pressure in the water storage cylinder 9 will increase. When the pressure in the water storage cylinder 9 increases, the sealing tube 11 will move upward under the action of pressure, and the spring 10 will undergo elastic deformation. During the upward movement of the sealing tube 11, the second pressure regulating port 13 will also move upward. When the second pressure regulating port 13 moves to one side of the first pressure regulating port 12, oxygen will be discharged from the opening of the first pressure regulating port 12 and the second pressure regulating port 13. When the pressure in the water storage cylinder 9 is greater, the sealing tube 11 will continue to move upward, thereby enlarging the opening formed between the first pressure regulating port 12 and the second pressure regulating port 13, and the discharged oxygen will increase, which is convenient for quickly adjusting the air pressure in the water storage cylinder 9, thereby improving the stability and safety of user use.

[0020] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
