Solution Overview
Problem
Conventional heating inhalers lack the ability to adapt to different medications, making them inconvenient for various patient needs, as they can only simply heat medicine without adjusting for specific requirements.
Innovation Solution
A heating inhaler with a control circuit board, sensing element, and indicating element that detects suction action and adjusts power supply to the atomizer based on predetermined time periods, ensuring appropriate heating and indicating the operational state to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional heating inhalers simply heat the medicine without detection or control mechanisms, then the device structure remains simple, but the adaptability to different patient needs and medications is poor
Solution Approach 1:
The patent implements feedback control by using a sensing element to detect suction actions and feed this information back to the control circuit board, which then adjusts the power supply to the heating assembly accordingly. This closed-loop feedback mechanism enables the inhaler to adapt to different patient needs and medication types while maintaining reasonable device complexity through automated control.
Solution Approach 2:
The inhaler performs self-adjustment of heating parameters based on automatic detection of suction actions without requiring manual intervention from the user. The control circuit board automatically regulates power supply duration and intensity based on sensing element input, allowing the device to serve itself in adapting to different medication requirements.
2Loss of energy
If the heating inhaler operates without time control, then the operation is simple, but power is wasted and the service life is shortened
Solution Approach 1:
The patent implements periodic action by controlling the power supply to the heating assembly in discrete time periods based on detected suction actions. The control circuit board activates heating for predetermined durations (first and second time periods) rather than continuous operation, reducing energy waste while extending device service life through controlled intermittent heating cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the convenience of operation by ensuring the heating inhaler adjusts its operation according to the detected suction action and the type of medication, preventing waste and prolonging the device's service life by optimizing power usage and adherence to medication administration standards.
Implementation Method 1
electrically heating of tobacco, tobacco products or tobacco product analogues
Implementation Method 2
heating the medicine to release the effective substance contained in the medicine
Implementation Method 3
When an air flow flows into the housing through the air inlet hole and flows to the atomizing cavity, the sensing element senses a change of the air flow and detects a suction action
Implementation Method 4
atomizer...heating the medicine to release the effective substance contained in the medicine
Data Source
AI summary
The present disclosure relates to a heating inhaler and a controlling method thereof. The method includes: the sensing element detecting a suction action, and if the sensing element detects the suction action within a first predetermined time period, the control circuit board controlling the power source to supply power to the atomizer for a second predetermined time period then stop supplying, wherein the indicating element displays a first state within the second predetermined time period until the power source stops supplying power to the atomizer, then the indicating element displays a second state. If the sensing element detects no suction action within the first predetermined time period, the control circuit board controlling the power source to stop supplying the electric power to the atomizer, and the indicating element displaying the second state.
