In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
As shown in fig. 1-5, an embodiment of the present invention provides an oxygen generator 10, including a device housing 11, a control circuit board 126, a power supply device 129, an oxygen storage tank 121, a compressor 112, a plurality of air filters 110 connected to an input end of the compressor 112, a plurality of molecular sieves 120 connected to an output end of the compressor 112 through a reversing valve 118, wherein the molecular sieves 120 are connected to the oxygen storage tank 121, and the oxygen storage tank 121 is connected to an oxygen interface 15 disposed on one side of the device housing 11 through an oxygen pipeline 123; an air flow sensor 111 is arranged on an air inlet pipeline 114 between the input end of the compressor 112 and the air filter 110, a temperature sensor 113 is arranged corresponding to the compressor 112, an oxygen sensor 125 is arranged on an oxygen pipeline 123 between the oxygen storage tank 121 and the oxygen interface 15, and the air flow sensor 111, the temperature sensor 113 and the oxygen sensor 125 are connected with the control circuit board 126.
As shown in fig. 5, the control circuit board 126 is connected to a speaker 139 and an LED indicator 138, and when one of the intake air flow data collected by the air flow sensor 111, the compressor temperature data collected by the temperature sensor 113, and the oxygen concentration data and the oxygen flow data obtained by the oxygen sensor 125 deviates from a preset interval, an audible and visual alarm is issued.
As shown in fig. 5, a timing device 140 is integrated on the control circuit board 126, and the timing device 140 is used for acquiring the accumulated usage time of the oxygen generator 10. Specifically, the timing device 140 may be a crystal oscillator or a processor integrated clock module.
The existing oxygen generator is usually integrated with an oxygen sensor and an operation state sensor for electrical elements such as a compressor and an electromagnetic valve, although the oxygen flow data and the oxygen concentration data can be monitored in real time through the oxygen sensor, so as to judge whether the compressor works normally, factors causing changes of the oxygen flow data and the oxygen concentration data are numerous, such as a molecular sieve failure, an oxygen storage tank failure, a compressor failure and the like, that is to say, the existing oxygen generator operation state monitoring parameters lack pertinence, and the monitoring effect is poor. The condition that the running state of the oxygen generator is abnormal is found in the long-term operation and use process and mainly comprises the following points: firstly, air inlet blockage, secondly, compressor failure, thirdly, molecular sieve failure and fourthly, devices such as a reversing valve and the like are damaged due to long-term use. Aiming at the discovery, the running state of the oxygen generator is monitored more accurately by monitoring the accumulated service time of the oxygen generator, the air inlet flow data, the temperature data of the compressor, the oxygen concentration data and the oxygen flow data, and when the data are abnormal, a user is prompted to solve or inform a manufacturer of maintenance service.
The oxygen sensor 125 is of a wide variety, such as an electrochemical oxygen sensor, a zirconia oxide sensor, a fluorescence quenching oxygen sensor, and the like.
The electrochemical (electrochemistry) sensor has the characteristics of low use cost and accurate measurement. Electrochemical (electrochemical) sensors, however, use semi-permeable membranes, and over time, both the membrane properties and the electrode properties change. These inherent characteristics result in electrochemical (electrochemical) sensors that need to be replaced frequently, and also require periodic calibration. The defect is that the working temperature is generally 0-50 degrees, the working effect is good under the environment of normal temperature (25 degrees), but the temperature exceeds 40 degrees, the service life is consumed very fast; when the device is used in different air pressure environments, recalibration is needed.
The zirconium oxide sensor is an oxygen sensor with stable performance and long service life. The zirconia oxide sensor has the advantage of faster response speed compared to the paramagnetic sensor, but since the zirconia oxide sensor is a high temperature sensor, the start-up warm-up time of the instrument is longer compared to the paramagnetic sensor. And, according to the principle of the zirconia sensor, this is not suitable for use in an environment where a reducing gas is present (e.g., hydrocarbon gas, hydrogen, carbon monoxide). The zirconia must be above 650 deg. to work, so the zirconia sensor needs to be considered for environmental safety when working.
Lox-02The fluorescent oxygen sensor is based on the principle that fluorescence encounters molecular oxygen quenching, and oxygen absorbs the spectrum of the blue part in light. Oxygen causes quenching of the fluorescence emitted by the particular ruthenium compound, so that the intensity of the emitted light changes, and the time for which the intensity of the fluorescence changes is related to the concentration of oxygen. The optical oxygen principle is performed every timeThe detection can not affect the detected environmental gas. The oxygen is not consumed during detection, which is different from other oxygen sensors, and the oxygen is consumed so as to change the component proportion of the detected gas. The light intensity variation time can be calibrated to obtain an accurate oxygen partial pressure value which is not influenced by the air pressure variation. When calibrating the oxygen concentration to obtain an accurate oxygen measurement, the sensor is completely inert and does not consume any oxygen to be measured. Meanwhile, the sensor is internally provided with an air pressure chip, and the built-in software calculates the oxygen concentration. When in use, the oxygen partial pressure value, the atmospheric pressure value and the oxygen concentration value can be read only by sending commands.
Optionally, the oxygen sensor 125 is an ultrasonic oxygen sensor, and is configured to collect oxygen concentration data and oxygen flow data in the oxygen pipeline. The ultrasonic oxygen sensor is used for measuring the gas flow and the oxygen concentration in binary gas, adopts an ultrasonic detection technology, is superior to electrochemistry and other oxygen sensors, has the functions of numerical value display, online monitoring, state alarm and the like, and is widely applied to occasions such as household and medical oxygenerators, oxygen production chambers and the like.

A temperature sensor is a sensor that senses temperature and converts it into a usable output signal.

The thermometer reaches thermal equilibrium through conduction or convection, so that the indication value of the thermometer can directly represent the temperature of the measured object. Generally, the measurement precision is higher; the thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range.
The sensing element of the non-contact temperature sensor is not contacted with the measured object, and is also called a non-contact temperature measuring instrument. Such a meter can be used to measure the surface temperature of moving objects, small targets and objects with small heat capacities or fast temperature changes (transients), and also to measure the temperature distribution of the temperature field.
