Solution Overview
Problem
Current handheld cigarette purifiers are inconvenient, pose risks of scalding and ash falling, and have low efficiency in reducing second-hand smoke pollution.
Innovation Solution
A handheld automatic cigarette-lighting purifier with a cigarette holding chamber and integrated smoke purification device, featuring a cigarette-lighting device at one end and check valves to control airflow, ensuring automatic lighting and containment of smoke within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handheld cigarette purifier is designed with separate insertion steps (cigarette into holder, then holder into device), then the structure can be simple, but the operation becomes inconvenient and risks of scalding and ash falling increase
Solution Approach 1:
The cigarette holder and purification device are integrated into a single unified structure. The cigarette holding chamber is directly formed within the purification device housing, eliminating the need for separate holder and device components. This merging allows users to insert the cigarette directly into the chamber without intermediate steps, improving operational convenience while maintaining structural simplicity through functional integration.
2Object-generated harmful factors
If the cigarette is inserted into the purification device after being lit, then the device structure can be simpler, but smoke gas is generated and pollutes the environment before purification
Solution Approach 1:
The cigarette-lighting device is pre-positioned within the cigarette holding chamber at the opposite end from the chamber opening. This preliminary arrangement of the lighting component allows the cigarette to be lit automatically upon insertion, ensuring the burning cigarette remains contained within the purification device from the moment of ignition, thereby preventing unfiltered smoke release into the environment.
3Object-generated harmful factors
If check valves are added to control airflow direction, then smoke containment is improved, but device complexity increases
Solution Approach 1:
Check valves are integrated into the airflow pathways at the air intake port and air inlet of the smoke purification device. These valves utilize pneumatic pressure differential to automatically control airflow direction - allowing air to flow only toward the cigarette holding chamber and smoke purification device respectively, while preventing reverse flow. This pneumatic control mechanism ensures smoke containment without requiring complex mechanical or electronic control systems.
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
The solution allows for convenient, safe operation with reduced risk of scalding and ash falling, and effectively prevents the release of unfiltered second-hand smoke, improving upon the inefficiencies of prior designs.
Implementation Method 1
the cigarette-lighting member is resistance wire
Implementation Method 2
a first check valve is provided at the air intake port to allow air to only flow toward the cigarette holding chamber, and a second check valve is provided at the air inlet of the smoke purification device to allow air to only flow toward the smoke purification device
Implementation Method 3
a smoke purification device located around the cigarette holding chamber

AI summary
An automatic cigarette-lighting purifier includes a cigarette holding chamber and a smoke purification device, one end of the cigarette holding is provided with a chamber opening which is communicated with the smoke purification device and the cigarette holding chamber, and a cigarette positioning member is provided at the chamber opening. The automatic cigarette-lighting purifier further includes a ventilation end cap that is movable to cover the end of the cigarette holding chamber that is opposite to the chamber opening, and a cigarette-lighting member is at one side of the ventilation end cap. A cigarette can be lighted automatically by the cigarette-lighting device once it's placed in the automatic cigarette-lighting purifier, and the burned cigarette is always kept in the automatic cigarette-lighting purifier, thus no unfiltered second-hand smoke is produced. Furthermore, the structure of the automatic cigarette-lighting purifier according to the present invention is simple, the operation is convenient, and the possibilities of scalding and cigarette ash falling are prevented.
