Problems solved by technology

But these atomizing devices all have the following disadvantages: the rate of atomization (the amount of mist sprayed per unit time) is slow about 2-3mg / s, resulting in long administration time, continuous atomization for 3-5 minutes; inhalation administration The operation is cumbersome and the compliance is poor; during the administration process, no matter whether the user inhales the mist, the device is spraying, so that the user inhales too much medicine, and the medicine is wasted seriously; due to the limitation of the atomization principle, these devices increase the size of the mist After the speed is increased, the proportion of 1-5 micron droplets in the mist droplets will be greatly reduced, the proportion of drugs entering the lungs will be small, and the waste of drugs will increase.
In addition, the existing net-type atomization device lasts for a long time. If the atomizer works continuously for a long time (several minutes) at a high voltage greater than 70 volts, the ceramic on the atomizer will heat up, and it is difficult to ensure the adhesion of the glue on the atomizer. performance, it is also difficult to guarantee the stability of atomized ceramic performance

Embodiment 1

[0083] An atomizing device, comprising:

[0084] Atomizing tablet, used for atomizing medicine, with rated voltage;

[0085] The voltage control element is electrically connected with the atomizing sheet, and is used to provide the atomizing sheet with a working voltage, the working voltage is not less than 70V, and the working voltage is 60% to 150% of the rated voltage of the atomizing sheet.

[0086] When the working voltage is not less than 70V and is 60% to 150% of the rated voltage of the atomized tablet, the atomization rate can be significantly improved, and the time of drug administration can be shortened from a few minutes to a few seconds in combination with the synchronization of the spray and the patient's inhalation Clock, can be used with great convenience. And a few seconds of high-voltage work every day will not make the atomizer heat up, nor will it shorten the service life too much. When the working voltage exceeds the rated voltage too much, there will be...

Embodiment 2

[0104] An atomizing device, comprising:

[0105] Atomizing tablet, used for atomizing medicine, with rated voltage;

[0106] The voltage control element is electrically connected to the atomizing sheet, and is used to provide the atomizing sheet with an operating voltage, and the ratio of the operating voltage to the rated voltage of the atomizing sheet is greater than 100% and not greater than 150%.

[0107] When the ratio of the working voltage to the rated voltage of the atomizing sheet is greater than 100% and not greater than 150%, the atomizing sheet can work under overload, thereby increasing the atomization rate. The rated voltage of the atomizer can be known from the product manual of the atomizer. When the working voltage exceeds the rated voltage too much, there will be liquid droplets sprayed from the atomizing sheet and the atomizing sheet will become hot, the proportion of 1-5 micron droplets will decrease, the atomization effect will be poor, and the working vo...

Embodiment 3

[0125] Using the atomization device and rapid atomization method in Example 1 or Example 2, the commonly used atomizing sheet with a rated voltage of 90V on the market was tested, and the results are shown in Table 1 below:

[0126] Table 1

[0127]

[0128] The atomizers used in the above table are commonly used in the market with a rated voltage of 90V. From the test results in the above table, it can be seen that when the working voltage provided to the atomizer is not less than 70V, and the working voltage is fog The rated voltage of the atomizing tablet is 60% to 150%, or when the ratio of the working voltage supplied to the atomizing tablet to the rated voltage of the atomizing tablet is greater than 100% and not greater than 150%, the atomization rate and atomization rate of the drug are effectively improved. The speed of movement, especially the atomization rate is significantly improved, and the proportion of 1-5 micron droplets is almost unchanged. When the ratio o...
