Referring to fig. 1 and 2, the present embodiment provides a sterilization method for an oxygen generator 100, which includes:
s1: controlling the compressor 130 and the cooler 140 to start;
s2: receiving a temperature signal indicative of an internal temperature of oxygenerator 100;
s3: the power of the cooler 140 is adjusted and kept for a preset time in case that the internal temperature is a preset temperature.
Referring to fig. 1 and 2, the operating principle of the sterilization method of the oxygenerator 100 is as follows:
the sterilization method of the oxygenerator 100 comprises the following steps: controlling the compressor 130 and the cooler 140 to start; receiving a temperature signal indicative of an internal temperature of oxygenerator 100; adjusting the power of the cooler 140, and preserving the heat for a preset time when the internal temperature is a preset temperature;
the temperature of the gas after being compressed by the compressor 130 is increased by controlling the compressor 130, and after the compressed air flows through the cooler 140, the temperature inside the oxygenerator 100 can be adjusted by adjusting the power of the cooler 140, so that the internal temperature of the oxygenerator 100 reaches a proper sterilization temperature, that is, a preset temperature condition, and after the preset temperature condition is reached, the internal temperature of the oxygenerator 100 can be sterilized by preserving the heat for a preset time;
therefore, the sterilization method of the oxygenerator 100 controls the heat generated by the operation of the compressor 130, so that the interior of the equipment reaches the sterilization temperature, and after the sterilization temperature is maintained for a period of time, most of bacteria in the interior of the equipment are inactivated, so that the equipment is more sanitary, the sterilization effect is obvious, the sterilization efficiency is high, and the cost is low.
Further, in the present embodiment, when the internal temperature of the oxygenerator 100 is adjusted to reach the sterilization temperature, the power of the cooler 140 is adjusted, which specifically includes the following steps:
in case that the internal temperature is greater than the preset temperature, increasing the power of the cooler 140 until the internal temperature is the preset temperature;
in the case that the internal temperature is less than the preset temperature, the power of the cooler 140 is reduced until the internal temperature is the preset temperature.
In the embodiment, the preset temperature is 60-100 ℃; the preset time is 1min-40min. In this embodiment, the preset temperature is set to 80 ℃ and the preset time is set to 10min.
Further, in the present embodiment, in the process of sterilizing the interior of the oxygenerator 100 by using the above, the heat dissipation can be reduced by controlling the flow valve 170, so that, in the case that the internal temperature is within the preset temperature range, the steps of the sterilization method of the oxygenerator 100 further include:
the flow rate of the flow valve 170 is adjusted such that the operating flow rate of the flow valve 170 is less than the set flow rate of the flow valve 170.
Outside, the control of the flow valve 170 can be combined with the cooler 140 to reasonably control the temperature inside the oxygenerator 100; for example, in the process of adjusting the internal temperature, the cooler 140 is controlled to adjust the temperature thereof, and the flow valve 170 is also adjusted to increase the flow rate of the discharged air flow when the internal temperature is too high, so that the heat is rapidly dissipated, and the internal temperature is rapidly reached to a proper temperature; conversely, when the temperature is too low, the flow valve 170 may be controlled to reduce the flow of the discharged air flow so that the heat dissipation speed is slowed down to allow the internal temperature to quickly reach the proper temperature.
In this embodiment, after the sterilization step is completed, the normal operation state of the oxygenerator 100 needs to be restored, that is, the steps after the preset time of heat preservation include:
the flow of the flow valve 170 is adjusted such that the flow valve 170 operates at a set flow rate.
In addition, the power of the cooler 140 is adjusted until the internal temperature is the operating temperature.
Wherein, in this example, the operating temperature is 30 ℃ to 60 ℃.
Based on the above, please refer to fig. 1 and 2, the present embodiment further provides an oxygen generator 100 for implementing the above-mentioned sterilization method of the oxygen generator 100, which includes a main body 110, a filtering unit 120, a compressor 130, a cooler 140, an adsorption component 150, an oxygen tank 160, a flow valve 170 and a temperature sensor 180;
the filtering unit 120, the compressor 130, the cooler 140, the adsorption assembly 150, the oxygen tank 160 and the flow valve 170 are all connected with the main body 110 and are sequentially communicated through pipelines; the main body 110 is provided with an air inlet 111 and an oxygen outlet 112, the air inlet 111 is communicated with the filtering unit 120, and the oxygen outlet 112 is communicated with the outlet of the flow valve 170; the temperature sensor 180 is connected to the main body 110, and serves to detect an internal temperature of the main body 110.
Referring to fig. 1 and 2, the working principle of the oxygenerator 100 is as follows:
the filtering unit 120, the compressor 130, the cooler 140, the adsorption assembly 150, the oxygen tank 160 and the flow valve 170 of the oxygenerator 100 are all connected with the main body 110 and are sequentially communicated through pipelines; the working flow is as follows: air entering through the air inlet 111 enters the device through the filtering device, the compressor 130 pressurizes the air, the cooler 140 cools the pressurized air, the cooled air is adsorbed by the adsorption component 150, and the adsorbed oxygen is discharged from the oxygen outlet 112 through the oxygen tank 160 and the flow valve 170; in this process, the flow valve 170 may be used to adjust the flow of oxygen from the oxygen tank 160 to a suitable flow for use by the user.
On the basis of the above structure, referring to fig. 1 and 2, the adsorption assembly 150 includes an on-off control valve 151, a first adsorption tower 152 and a second adsorption tower 153; the on-off control valve 151 is communicated with the cooler 140, the air inlet ends of the first adsorption tower 152 and the second adsorption tower 153 are communicated with the on-off control valve 151, and the air outlet ends of the first adsorption tower 152 and the second adsorption tower 153 are communicated with the oxygen tank 160; the main body 110 is also provided with an exhaust port 113 communicating with the on-off control valve 151.
By the arrangement mode, the first adsorption tower 152 and the second adsorption tower 153 are communicated with the cooler 140 through the on-off control valve 151, and the on-off control valve 151 can control the conduction state of the first adsorption tower 152 and the second adsorption tower 153 and the cooler 140 to be communicated with the cooler 140 alternatively; therefore, when the first adsorption tower 152 is communicated with the cooler 140 through the on-off control valve 151, the second adsorption tower 153 is blocked from the cooler 140, pressurized air is input into the first adsorption tower 152, the pressurized air is adsorbed by the molecular sieve in the first adsorption tower 152, and then enters the oxygen tank 160 after passing through the first adsorption tower 152, when the first adsorption tower 152 works for a period of time, the on-off control valve 151 switches the gas path to be communicated with the second adsorption tower 153, the gas path generates oxygen through the second adsorption tower 153, at the moment, the air inlet end of the first adsorption tower 152 is communicated to the air outlet 113, the air outlet 113 is connected with the atmosphere, the pressure in the first adsorption tower 152 is released for desorption and exhaust, and thus, continuous oxygen generation is realized through the work switching of the first adsorption tower 152 and the second adsorption tower 153, so that the oxygen generation efficiency is improved;
referring to fig. 1 and 2, when the oxygenerator 100 is operated for a period of time or needs to be sterilized, the method can be adopted, and the compressor 130, the cooler 140 and the flow valve 170 are controlled, and the on-off control valve 151 is combined to control the conduction of the first adsorption tower 152 and the second adsorption tower 153, so that the temperature inside the oxygenerator 100 is increased, and after reaching the preset temperature, the temperature is kept for a preset time, so that the interior of the oxygenerator 100 is sterilized, and the specific steps are not repeated herein.
In summary, the sterilization method of the oxygenerator 100 provided in this embodiment may be completed by using the oxygenerator 100, so that the oxygenerator 100 does not need to be structurally upgraded and reformed in the sterilization process, and thus, sterilization can be performed by using the internal structure of the oxygenerator 100, thereby reducing sterilization cost, and the sterilization effect is obvious and the sterilization efficiency is high.
The present invention is not limited to the above embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
