Abstract: A constant power control device of an active vaporization suction apparatus includes a power unit, a first load matching unit, a matching control unit, a second load matching unit, and a constant current generation unit. To replace a medication box along with a liquefied medication within, a new medication box is mounted on the constant power control device, and the first load matching unit is electrically connected to a load unit of the replaced medication box. The first load matching unit determines a load value of the load unit. The second load matching unit and the constant current generation unit generate a constant current signal according to the load value, and transmit the constant current signal to the load unit, thus allowing the load unit to vaporize the liquefied medication with a constant power. The present invention prevents the constant power from changing due to medication box replacements.

Abstract: The invention discloses a method and a device for producing a medicine particle flow, belonging to medical health care instruments. The device is characterized by comprising a water mist production device equipped with an ultrasonic atomization device and a fan, and a first closed channel equipped with a heating device, wherein a water mist guide outlet of the water mist production device is connected with a water mist inlet of the first closed channel. Compared with the prior art, the method and the device of the invention have the advantage that effective components of Chinese herbal medicines without volatility can reach the skin together with steam in the form of fine particles, or even molecules, so as to be conveniently absorbed by the skin.

Abstract: The present invention is an active vaporization suction system and a controlling method thereof. The system includes a medication device and an active suction device. The medication device is detachably mounted on the active suction device. When a suction module is suctioned, a flow module outputs a launching signal to a control module. The control module outputs a vaporization current control signal to a power supply module according to the launching signal. The power supply module generates and outputs a Joule vaporization current to a Joule vaporizer of the medication device according to the vaporization current control signal, so that the Joule vaporizer vaporizes a liquefied medication in a vaporization chamber into a vapor medication. In this way, when the user actively sucks the suction module, the user can take the vapor medication for medical treatment, which increases an absorption rate of the vapor medication.
