Intelligent atomizer control method

The invention relates to an optimal working frequency of the piezoelectric element automatically adjusted when assembling the spray head, and each spray program can easily obtain the same amount of flow agent to be sprayed, and can detect the abnormality of the working frequency at any time during the spraying process, and The use case can be used to record the control and management methods used by external resources, especially the control method of a smart atomizer.

Recently, the inhalation type nebulizer developed by the application of MEMS technology can produce fine mist droplets to make the medicine finer and improve the absorption efficiency of the medicine, and the atomizer is convenient to carry around, bringing great convenience to the patient. However, after long-term atomization of the liquid atomizer, the spray head is often prone to blockage. Because it is difficult to clean, the spray head of the atomizer can be disassembled and replaced, and also has patient medical care. Health and safety advantages.

Basically, the atomizer that can be disassembled and replaced with a spray head has the technical problem of replacing the spray head with the piezoelectric actuator of the spray head, due to the vibration of each component or the vibration of each porous metal orifice. The characteristics are different (and inconsistent), causing the operating frequency of the piezoelectric element to be adjusted, otherwise the normal atomization performance cannot be achieved; although the conventional technology has this problem, such as directly obtained from the piezoelectric element (vibration sensor) The method of feedback signal is used for frequency adjustment, but the accuracy of such feedback signal is not high and easy to be misjudged; for this reason, the new patent case of "Micro-atomizing device structure of detachable nozzle" of the Republic of China Announcement No. M378790 is used. It is through the (manual) adjustment of the variable resistor or the variable capacitor to achieve the frequency conversion or adjustment to set the piezoelectric element. The working frequency, however, the user of the atomizer (consumer), without the aid of electrical testing equipment, will have reference to the adjustment process without any scientific data for adjustment, and it is true that the optimal working frequency is called. Difficulties, and this improvement scheme, also caused the inconvenience of manual frequency modulation and the trouble of how to adjust the frequency after the replacement of the spray head; the inventor of the present invention invented Taiwan Invention Patent Publication No. 201325730 "Removable spray head resonance frequency of the atomizer" The adjustment method and structure" is to use the microcomputer frequency chasing technology to automatically adjust the resonance (optimal working) frequency of the piezoelectric element to avoid the inconvenience or error caused by the manual frequency adjustment, but this frequency chasing technology is in the new installation. The operating frequency adjusted when the spray head is applied and locked. During the subsequent spray application, the piezoelectric element is always operated at the locked frequency, even if the abnormality of the piezoelectric element or the orifice sheet has affected the fine mist droplets. The degree of the atomizer does not make timely detection that the operating frequency of the piezoelectric element must be readjusted.

That is to say, the fine mist droplets generated by the atomizer can affect the absorption effect of the drug. Generally, the user cannot judge the small difference in the degree of miniaturization from the appearance of the sprayed mist, and the difference is large. When it is found that the spray is not normal, it may have experienced an ineffective or poorly effective absorption treatment; for example, the obstruction of the orifice sheet is slowly blocked, rather than blocking the spray in a short period of time is obviously abnormal, generally In a case where the orifice sheet is slightly blocked, the natural frequency of the piezoelectric element combined with the orifice sheet may start to change or has changed abnormally. At this time, the operating frequency of the original adjustment lock of the microcomputer may or may not be an ideal resonance frequency. And the degree of micro-fog droplets should be slightly deteriorated; the degree of this deterioration is more and more obvious as the degree of obstruction of the orifice sheet becomes more and more serious, and the fineness of the micro-mist droplets becomes significantly changed. When it is necessary to replace the spray head, the piezoelectric element may or may have been operating at a non-resonant frequency for a period of time, and the user's use of the atomizer during this time is often due to absorption. Poor or poor, while reducing or losing Efficacy; if the atomizer itself can detect whether the working frequency of the piezoelectric element is the resonant frequency at any time during use, the above situation can be improved by timely re-frequency chasing and adjustment of the working frequency; The component is not abnormal at the resonant frequency state, except that the piezoelectric component or the orifice plate is severely deformed, broken, the wire is detached or the assembly is incorrect, and the resonance frequency cannot be adjusted by the microcomputer, if only the slight deformation In the case where the natural frequency is slightly changed, when the atomizer itself has a detecting function of whether the piezoelectric element operates in a resonance state, the normal fogging effect can be maintained by re-following and adjusting the operating frequency.

In addition to the above cases, the use of conventional nebulizers, due to each spray procedure, the user can only judge the amount of liquid ejected according to the scale or experience or feeling on the liquid tank, lack of scientific data as the spray amount As a result, it is easy to use too much or too little spray dose in one procedure, resulting in waste of medical resources or affecting the curative effect; and whether the user uses the nebulizer normally on time, because the conventional nebulizer does not have automatic record of history, resulting in The user usually uses the dictation or handwritten record of the memory to let the caregiver (family) know the usage, including the medical staff (doctor), and can only obtain medical information from the dictation or handwritten report of the user or the caregiver. Inappropriate medical treatment, assistance or assistance with errors or deficiencies, and medical insurance, dictation or handwritten reports, should be difficult to prove that the user has been obligated to use the liquid agent; and the pharmaceutical factory and or atomizer producers are even less able to The information used by the liquid or atomizer is thus obtained and utilized.
