For example, children often cough, if treated with traditional medications or injected with needles, the mind of most children is discouraging and fear of taking medication. And the absorption of the medicine through muscles or blood is relatively slow, so that children are exposed to the decoction for a long time. The aerosol inhalation is characterized in that gas is suddenly decompressed through a narrow opening, the negative pressure generated at local part sucks out liquid medicine to form fog particles, the aerosol inhalation drug therapy is a common therapy method for children asthmatic diseases or acute asthma attacks, and the curative effect is rapid and reliable, so the aerosol inhalation drug therapy is increasingly popular with hospitals and parents. The medical atomizers commonly used at present mainly comprise a compression atomizer, an ultrasonic atomizer and a mesh atomizer. However, in practical use, several common atomizers have more or less defects. For example, for an ultrasonic atomizer, the particles generated by the ultrasonic atomizer are large and the atomization is fast, so that a patient inhales excessive water vapor, a respiratory tract is humidified, thick and dry secretions originally partially blocking a bronchus in the respiratory tract expand after absorbing water, respiratory tract resistance is increased, and an oxygen deficiency phenomenon may occur. The mesh type atomizer, which is constructed to spray through a nozzle-shaped mesh type spray head by vertical vibration of a vibrator, has both features of a compression type atomizer and an ultrasonic atomizer in a spray manner of spraying by using minute ultrasonic vibration and a mesh type spray head structure, and is an atomizer suitable for patients with asthma in children. However, the portable home entertainment system is small in size and convenient to carry, and accordingly the cruising time period is short in intelligentization degree, and therefore the portable home entertainment system is only suitable for the home environment.
