Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to an oxygen production machine without water humidification. Background Art

[0002] An 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, distillation is performed 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] The oxygen produced by traditional oxygen concentrators is dry, which can irritate the upper respiratory tract and cause discomfort. Therefore, the oxygen needs to be humidified and can only be used by patients after being connected to an external humidification cup. The existing humidification cup is usually a small bottle. Pure water is passed into the bottle. The oxygen is humidified after being filtered by the pure water. The humidification cup will produce a certain amount of dirt inside after long-term use. This dirt will affect the quality of the oxygen. In addition, since the structure of the oxygen concentrator and the humidification cup is not easy to clean, it will cause trouble for the existing oxygen concentrator to produce oxygen.

[0021] Reference Figure 1-3 The utility model provides an embodiment: an oxygen concentrator without water humidification, comprising an oxygen concentrator box 1, an air inlet 2 is provided on the left side of the oxygen concentrator box 1, a high-pressure fan 3 is installed in the oxygen concentrator box 1, the high-pressure fan 3 corresponds to the position of the air inlet 2, a coarse filter 4 is installed on the right side of the high-pressure fan 3, a compressor 5 is installed on the right side of the coarse filter 4, a condenser 6 is connected to the right side of the compressor 5, an atomizer 7 is installed on the right side of the condenser 6, the atomizer 7 is connected to the air outlet pipe 8, a controller 9 is installed on the oxygen concentrator box 1, and the high-pressure fan 3, the compressor 5, and the condenser 6 are connected to the controller 9.

[0022] The lower end of the condenser 6 is connected to a water pipe 10, and a pressure pump 11 is installed on the water pipe 10. The pressure pump 11 is connected to the controller 9. The other end of the water pipe 10 is connected to the atomizer 7 to pressurize the condensed water to facilitate its faster atomization. The oxygen generator 1 is provided with an air outlet 12, and the air outlet 12 corresponds to the position of the air outlet pipe 8 and cooperates with each other. The rear side of the oxygen generator 1 is provided with a heat dissipation port 13. The right end of the condenser 6 is connected to a molecular sieve 14, and the molecular sieve 14 corresponds to the position of the air outlet pipe 8. The molecular sieve 14 separates the nitrogen in the high-pressure and low-temperature air from the oxygen. The gas molecules are adsorbed in the sieve holes of the molecular sieve 14, and the separated oxygen is discharged from the outlet pipe 8. A cooling pipe 15 is connected between the coarse filter 4 and the compressor 5. The temperature of the air after extraction and filtration is relatively high. After cooling, it is convenient to improve the efficiency of subsequent compression and molecular sieve adsorption.

An impurity collection tank 18 is installed at the corresponding position of the lower end of the coarse filter 4. The impurity collection tank 18 is connected to the oxygen production box 1 to collect dust and impurities filtered out by the coarse filter 4 in the tank.

[0023] Working principle: the controller 9 controls the oxygen generator to work, the high-pressure fan 3 draws the outside air from the air inlet 2 into the oxygen generator box 1, and after filtering by the coarse filter 4, the large particles, dust and other impurities in the air are filtered out, and the air after preliminary filtration is cooled by the cooling pipe 15 and enters the compressor 5. The compressor 5 reduces the volume of the air and increases the pressure by mechanical work, and transports the pressurized air to the condenser 6 to separate the gas and liquid first, and the condensed water is retained at the bottom of the condenser 6. The pressure pump 11 is controlled to pressurize the condensed water, and the condensed water is atomized by the atomizer 7. Then, the molecular sieve 14 adsorption technology is used to separate the oxygen molecules in the gas after the gas-liquid separation, and finally pure oxygen is obtained, which is output outward along the outlet pipe 8 together with the atomized water, thereby improving the problem of drying the oxygen prepared by the oxygen generator. At the same time, there is no need to connect an external humidification cup to prevent the water in the humidification cup from being left with dirt after treatment, thereby reducing the cleaning cost, avoiding the fluctuation of equipment performance caused by water evaporation or temperature change, and improving the stability of the oxygen generator operation.
