Instantaneous Smoke Heater with Direct Heating Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smoke generators require a longer preheating time due to indirect heating, leading to inefficient vaporization and increased electricity consumption, and they cannot continuously operate for extended periods without overheating, which poses risks to electronic components and increases volume and material costs.
Innovation Solution
The design incorporates a heating rod with a flow guiding member and outer tube configuration that allows for direct heating and rapid vaporization of oil, eliminating the need for heat accumulators and reducing standby heat maintenance, featuring shallow, rectilinear heating passages and annular grooves to enhance heat transfer and reduce heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If indirect heating through helical tube is used, then heat transmission is achieved, but preheating time increases to 5-10 minutes
Solution Approach 1:
The patent removes the helical tube intermediary component and directly contacts the heating rod with the oil in the heating chamber, eliminating the indirect heating path and reducing preheating time from 5-10 minutes to instantaneous heating
Solution Approach 2:
The heating chamber uses an asymmetric design where the heating rod directly penetrates into the oil reservoir area, creating unequal heat distribution paths that favor rapid heating of the oil surface and interface areas first
2Loss of energy
If helical tube with large contact area is used, then heat transmission surface is increased, but heat dissipation increases rapidly
Solution Approach 1:
The patent employs a thin-walled heating chamber that provides adequate heat transmission surface area while minimizing thermal mass and heat storage capacity, reducing the energy required to maintain temperature and lowering heat dissipation losses
Solution Approach 2:
The heating chamber wall thickness is optimized to change the thermal parameters, providing sufficient heat transmission area while maintaining low thermal inertia and reducing the energy required for heating and temperature maintenance
3Reliability
If heating rod maintains high temperature for standby, then timely smoke provision is ensured, but electronic components may be damaged
Solution Approach 1:
The heating chamber is pre-filled with oil that acts as a thermal buffer, allowing the heating rod to heat the oil rapidly when needed without requiring the rod itself to maintain extreme temperatures during standby, thereby protecting electronic components
Solution Approach 2:
The oil in the heating chamber serves as an intermediary thermal medium between the heating rod and the environment, absorbing and releasing heat as needed, which allows the heating rod to operate at lower temperatures during standby while still ensuring rapid smoke generation when activated
4Use of energy by stationary object
If heating rod operates intermittently to maintain temperature, then standby temperature is maintained, but electricity consumption increases
Solution Approach 1:
The heating rod operates continuously at a low power level rather than intermittently at high power, maintaining a stable temperature in the heating chamber with minimal electricity consumption, eliminating the energy losses associated with repeated heating cycles

AI summary
An instantaneous heater (51) is mounted in a casing (20) of a smoke machine (10). The instantaneous heater (51) includes a heating rod (52), a flow guiding member (131) mounted around the heating rod (52), and an outer tube (64) mounted around the flow guiding member (131). The flow guiding member (131) includes an inner periphery (137) abutting an outer periphery (58) of the heating rod (52). A shallow, rectilinear heating passage (151) is defined in the inner periphery (137) of the flow guiding member (131) to permit a small amount of oil to pass therethrough. The oil can be directly and completely heated and vaporized by the heating rod (52) into smoke.
