Description

Technical Field

[0001] This invention belongs to the field of combustion product removal or treatment technology, specifically relating to an integrated intelligent soldering iron smoke treatment device. Background Technology

[0002] During electronic soldering, the high-temperature fumes generated by the soldering iron tip contain harmful substances such as rosin volatiles and lead fumes, posing a threat to the health of operators. Related fume treatment equipment has evolved from traditional large-scale industrial purification equipment towards miniaturization and portability to suit small-scale soldering scenarios such as DIY and laboratories. Currently, the mainstream fume treatment solution is the use of a split-type soldering fume purifier. This type of equipment typically includes an independent fume extraction arm, a centrifugal fan, a multi-stage filtration chamber, and an independent control unit. The fume extraction arm is 500-800mm long and equipped with an independent fume collection hood. The filtration system consists of a pre-filter, a HEPA filter, and an activated carbon layer. It features fixed-speed fan adjustment and supports basic control modes such as timed shutdown. Fume collection relies on long-distance suction, and the response requires specific triggering. Although existing smart soldering irons (such as the ODGIRON open-source PD soldering iron) are very advanced in terms of temperature control and human-computer interaction, they do not integrate any fume treatment function themselves and must be used in conjunction with the aforementioned split-type purifier, forming a separate application model of "soldering equipment + independent fume treatment equipment".

[0003] Problems in the prior art: 1. The core shortcomings of split-type flue gas treatment solutions in this field; 1.1 The flue gas capture efficiency is low and the response is slow; Problems: When the smoke is drawn from a distance of 200-300mm, the actual collection efficiency is only 50-70%. There is a 3-5 second delay from smoke generation to purification activation, and a large amount of combustion products spread into the environment.

[0004] Cause analysis: Combustion products diffuse rapidly, long-distance capture is greatly affected by airflow, and there is an inherent time difference between fan start-up and acceleration, making it impossible to achieve real-time capture at the source.

[0005] Problems to be solved: Shortening the capture distance requires redesigning the equipment layout, but independent equipment design is difficult to overcome spatial limitations; improving the response speed requires optimizing the triggering mechanism, but there is a lack of linkage and perception with welding operations.

[0006] 1.2 Poor space occupancy and adaptability to usage scenarios; Problem: Split-type air purifiers require an additional 0.03-0.05㎡ of workspace, making them inflexible in small spaces such as dormitories and small laboratories.

[0007] Cause analysis: Independent flue gas treatment equipment requires separate structures such as fans and filter chambers, which inevitably creates additional space requirements, conflicting with the space constraints of miniaturized welding scenarios.

[0008] Problem to solve: Reducing the size of the equipment will directly lead to a decrease in air volume and a reduction in filter capacity, thereby reducing the filtration effect of combustion products, creating a contradiction between physical performance and space requirements.

[0009] 1.3 Insufficient coordination between energy efficiency and operating conditions; Problem: Standby power consumption is 5-8W, and operating power consumption is 50-80W. Regardless of whether soldering is being performed, it needs to run continuously or be manually started and stopped, resulting in energy waste.

[0010] Cause analysis: The independent control system cannot perceive the welding condition in real time, lacks a coordination mechanism with the working status of the soldering iron, and cannot dynamically adjust the purification power according to the amount of combustion products generated.

[0011] Overcoming difficulties: Achieving collaborative operation requires establishing a communication and status recognition mechanism between devices, but the interfaces of devices from different manufacturers are not standardized, and there is a lack of effective algorithm support for the rapid identification of welding conditions.

[0012] 1.4 Fragmented operational procedures; Problem description: The soldering iron needs to be started and stopped separately, the temperature needs to be adjusted, and the air purifier needs to be switched on and off and the fan speed needs to be adjusted, which interrupts the workflow and makes the operation very complicated.

[0013] Cause analysis: The separate design results in independent control logic for flue gas treatment and welding operations, failing to form an integrated operation system.

[0014] Overcoming difficulties: The integrated design needs to solve technical challenges such as structural interference and thermal management conflicts between the electric heating module and the flue gas treatment module.

[0015] 2. Core technological challenges of compact integration; 2.1 Performance balance of filtration systems under spatial constraints; Problem: High-efficiency filtration of combustion products requires sufficient filter volume, but the miniaturization of soldering irons limits the installation space of the filter module.

[0016] Analysis of the cause: The filtration efficiency and service life of HEPA filter cartridges and activated carbon layers depend on a certain thickness and contact area, which is fundamentally contradictory to the space requirements of portable devices.

[0017] The challenge lies in finding the optimal design that balances filtration efficiency, air resistance characteristics, service life, and size, thereby overcoming the performance bottlenecks of miniaturization and high-efficiency purification.

[0018] 2.2 Coordinated control of flue gas treatment and welding heating; Problem: The integrated heating system and purification system compete for power, and airflow may affect the stability of welding temperature.

[0019] Cause analysis: The USB PD power supply has limited power (65-100W) and cannot simultaneously meet the peak demand for rapid heating and high-volume purification; forced convection may disrupt the thermal balance of the soldering iron tip.

[0020] To address the challenges, an intelligent power distribution strategy and insulated airflow channels need to be designed to ensure both welding quality and the purification of combustion products.

[0021] Therefore, it is of great significance to develop a high-efficiency, compact smoke treatment device that can be deeply integrated with soldering irons and achieve intelligent linkage. Summary of the Invention

[0022] In view of the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide an integrated intelligent soldering iron smoke treatment device to solve the problems of low collection efficiency, large space occupation, poor operation coordination and inconvenient maintenance of traditional split solutions, and to achieve efficient source capture of smoke, compact device integration, intelligent linkage control and convenient maintenance.

[0032] Preferably, the control module is further configured with a filter life monitoring unit, which is used to record the usage time of the filter module and issue a replacement reminder.

[0033] The beneficial technical effects of this invention are as follows: 1. Highly efficient purification at the source, providing outstanding protection for environmental protection and health; Through a ring-shaped near-source suction structure, smoke is captured instantly within 15mm of the welding point, with a particulate matter filtration efficiency of ≥95% and a harmful gas removal rate of ≥90%, fundamentally changing the traditional situation of welding without purification or long-distance capture. The response time is <100ms, more than 30 times faster than split-type purifiers (3-5 seconds), effectively controlling PM2.5 concentration in enclosed spaces, significantly improving the working environment and protecting the health of operators.

[0034] 2. Highly integrated and compact, significantly improving space utilization efficiency; The suction, filtration, and control modules are all integrated into the soldering iron body, eliminating the need for external devices and saving 0.03-0.05㎡ of workbench space. The overall volume is only about 15% larger than that of traditional soldering irons, far less than the volume increase usually brought by separate solutions. It is especially suitable for space-constrained scenarios such as dormitories and laboratories, achieving efficient collaboration between the equipment and the space.

[0035] 3. Intelligent collaborative control significantly optimizes energy efficiency; Based on data from the soldering iron's built-in sensors, the system automatically identifies the soldering start / stop status and controls the purification system accordingly, achieving "on-demand switching on and off." Standby power consumption is ≤0.5W, reducing it by more than 90% compared to separate purifiers. During soldering, the purification intensity is dynamically adjusted according to the power change rate, avoiding ineffective high-energy-consumption operation, and improving the overall system energy efficiency by more than 30%.

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: The integrated intelligent soldering iron smoke removal device provided by this invention is built around core objectives such as efficient smoke capture, compact integration, intelligent linkage, convenient maintenance, and quiet operation. Specific solutions and embodiments are as follows: I. Source capture solutions for improving flue gas capture efficiency.

[0040] To overcome the shortcomings of separate devices, such as long capture distance and slow response, this invention innovatively integrates a ring-shaped air intake at the base of the soldering iron tip, forming an integrated structure of "near-source capture - instant air diversion".

[0041] The specific design includes: Annular close-range suction; the suction port adopts an annular design, closely surrounding the soldering iron tip, and the distance between its air inlet plane and the working surface of the soldering iron tip tip is controlled within 15 mm, realizing close-range closed capture of the point where welding fumes are generated.

[0042] Optimize the flow channel design; adopt a near-straight airflow channel to minimize the path of smoke from the generation point to the filter module, effectively reducing the diffusion loss of smoke during transmission.

[0043] High-efficiency negative pressure source; matched with a small, high-efficiency diaphragm pump as the negative pressure generating device, ensuring that sufficient suction can be provided to quickly draw smoke into the treatment system within limited space and power consumption.

[0044] II. Compact integrated solutions for space-saving purposes.

[0045] To address the issue of large size and space occupation of standalone devices, this invention highly integrates the flue gas treatment module inside the soldering iron body.

[0046] The specific design includes: Miniature power unit; an ultra-thin brushless diaphragm pump with an external dimension of only Φ25mm×15mm is selected to replace the traditional centrifugal fan, which greatly reduces the space occupied by the power unit.

[0047] Miniaturized filtration system; designed with a compact filtration module of approximately 8 cm³, integrating a multi-stage composite filtration structure of "electret high-efficiency filter media (physical filtration) + activated carbon (chemical adsorption)" to achieve high-efficiency purification in a very small space.

[0048] Integrated structural layout; through meticulous mechanical structure design, the air intake duct, filter module, diaphragm pump and control circuit are seamlessly integrated with the heating handle of the soldering iron, so that the overall size of the soldering iron with integrated smoke treatment function is only 15% larger than that of traditional models.

[0049] III. Intelligent linkage solutions for collaborative control.

[0050] To achieve adaptive coordination between the purification system and welding operations, this invention introduces an intelligent control strategy based on multi-sensor information fusion.

[0051] The specific design includes: Multimodal working condition sensing: The LIS3DHTR triaxial accelerometer built into the soldering iron senses the device's pickup / movement status, while the INA226 power monitoring chip accurately collects the real-time power of the heating circuit. The dual signals are fused to accurately determine the start and stop of the soldering process.

[0052] Main control and linkage logic: Using the GD32 series microcontroller as the core controller, the following linkage control is programmed to achieve: when welding is detected to start, the diaphragm pump is automatically started; after welding is completed, the diaphragm pump is controlled to run for a period of time and then automatically shut down to remove residual smoke.

[0053] Adaptive power regulation: The controller analyzes real-time power and its rate of change to predict the intensity of the current welding activity (amount of smoke generated), and dynamically adjusts the PWM (pulse width modulation) signal output to the diaphragm pump accordingly, so that its speed is intelligently matched within the range of 10% to 100%, achieving a precise correspondence between purification capacity and demand.

[0054] IV. Optimized design for filtration efficiency and thermal management.

[0055] Ensuring filtration efficiency and minimizing thermal interference with welding within a compact space are key challenges.

[0056] The specific design includes: High-efficiency, low-resistance filter media; the core of the filtration module uses high-efficiency, low-air-resistance HEPA-grade filter paper to ensure low air resistance while maintaining a high capture rate. Combined with activated carbon with high adsorption performance, it improves the overall filtration efficiency per unit volume.

[0057] Drive circuit optimization: An H-bridge drive circuit consisting of an S8550 PNP transistor and a DMN3032LE-13 MOSFET is used to precisely control the diaphragm pump. This circuit is highly efficient and can optimize overall power consumption while providing sufficient drive force.

[0058] V. Designed for ease of operation and maintenance.

[0059] To enhance user experience, this invention has been specifically optimized in terms of operation interaction and maintenance methods.

[0060] The specific design includes: Integrated human-computer interaction: The soldering iron body integrates an OLED display screen and multi-function buttons, which can display information such as the working status of the smoke treatment system and the remaining life of the filter in real time, and supports user settings of key parameters.

[0061] Modular quick-release maintenance; the filter module adopts an overall plug-in design, allowing users to replace the filter element within 30 seconds through a special opening on the device housing without tools.

[0062] Intelligent lifespan reminder: The control system has a built-in filter usage time accumulation function, which can actively remind users to replace the filter through the display screen or indicator light based on the preset lifespan threshold (e.g., 50 hours of cumulative operation).

[0063] VI. Noise reduction optimization solutions for operation.

[0064] To create a quiet operating environment, this invention implements systematic noise control.

[0065] The specific design includes: Ultrasonic drive; the frequency of the PWM signal controlling the diaphragm pump is set to around 25kHz, so that its main operating frequency is outside the range of human ear sensitivity, thereby reducing audible noise at the source.

[0066] Acoustic encapsulation and dissipation: Sound-absorbing cotton is filled around the diaphragm pump, and the air outlet is designed with a diffusion pattern to effectively absorb and attenuate mechanical vibration and airflow noise.

[0067] Overall noise control: Through the above comprehensive measures, ensure that the operating noise measured at a distance of 30 cm when the equipment is working normally does not exceed 40 decibels (dB(A)).

[0068] This embodiment uses a smart soldering iron powered by USB PD as the application platform.

[0069] Example: Implementation of an integrated intelligent soldering iron smoke treatment device.

[0070] Reference Figure 1 The integrated intelligent soldering iron smoke treatment device of this embodiment integrates all functional modules into the streamlined handle formed by the upper shell 1 and the lower shell 3 of the soldering iron. The overall appearance is similar to that of a traditional soldering iron, except that the lower half of the grip is slightly thickened.

[0071] 1. Specific implementation of the suction module: This module includes suction approaching the flue 4 and a miniature diaphragm pump 5.

[0072] The suction port 4, made of high-temperature resistant PEEK material, is precision-machined. Its front end is a ring-shaped suction port with an inner diameter of Φ6.5mm, which wraps around the Φ5mm soldering iron tip 14. The suction port plane is 12mm away from the tip of the soldering iron tip. It is fastened to the upper housing 1 by threads, and the airtightness of the interface is ensured by the suction port approaching the flue sealing ring 7.

[0073] Miniature diaphragm pump 5: Select a miniature pump of model FZ4002 (size Φ25mm×15mm, 5V power supply), which is fixed to the special chamber at the bottom of the handle by a shock-absorbing pad, and its exhaust port is aligned with the grille at the tail of the handle.

[0074] 2. Specific implementation of the filter module: The module adopts a drawer-type design that can be quickly disassembled and assembled.

[0075] The filter base 8 and filter top cover 12 are made of ABS plastic and are connected by four screws to form a sealed cavity with a volume of approximately 8 cm³. The bottom of the filter base 8 has an air inlet, which is interference-fitted with the air inlet of the micro diaphragm pump 5 through a silicone first filter sealing ring 6 to ensure airtightness.

[0076] Micro filter element 10: Features a multi-layered composite structure. The core filter layer is a folded electret meltblown fabric used to capture particles larger than PM0.3; its outer layer is wrapped with approximately 2 grams of a mixture of high-iodine-value activated carbon particles and zeolite filler to adsorb volatile organic compounds and odors. A second filter element sealing ring 9 and a third filter element sealing ring 11, made of polyurethane foam, are attached to the upper and lower ends of the filter element to ensure no side leakage within the cavity.

[0077] Connection and Replacement: The filter top cover 12 is connected to the side outlet of the suction duct 4 via a heat-resistant flexible silicone tube (150°C resistant) to the flue 13 (inner diameter Φ4mm). The entire filter module (including base, filter element, and top cover) can be pushed in or pulled out as a whole through an opening with a snap-fit ​​on the side of the lower housing 3 of the soldering iron. The replacement process requires no tools and takes less than 30 seconds.

[0078] 3. Specific implementation of control module and intelligent algorithm: The hardware and software of the control module are fully integrated on the main control board 2 of the soldering iron, and the main control chip adopts GD32F103C8T6 microcontroller.

[0079] Sensor signal input: The original LIS3DHTR triaxial accelerometer on the main control board 2 is used to detect the attitude and movement of the soldering iron; the original INA226 power monitoring chip is used to read the input power of the soldering iron heating circuit in real time (accuracy ±0.5%).

[0080] Intelligent control logic: The control program running within the microcontroller implements the following algorithms; Operating condition identification; set a power threshold (e.g., 5W) and a power rise rate threshold. When the accelerometer detects that the soldering iron is picked up from a horizontal stationary state (accelerometer change), and the INA226 detects that the power jumps from the standby state (<1W) and exceeds the threshold within 100ms, it is determined as a soldering start event.

[0081] Automatic start / stop: Once welding is detected to have begun, the program immediately outputs a high level through a GPIO port to drive an S8550 PNP transistor, thereby turning on the DMN3032LE-13 MOSFET that powers the miniature diaphragm pump 5. The diaphragm pump starts at 50% of its initial speed. When welding ends (power drops below the threshold and remains below for 2 seconds, and the accelerometer signal stabilizes), the program starts a 15-second delay shutdown timer, which shuts down the diaphragm pump after the timer expires.

[0082] Power adaptive adjustment: The program continuously calculates the sliding average of the power change rate. When this value is high, it indicates that large solder joints or drag soldering may be in progress, predicting a large amount of smoke generation. The program linearly increases the duty cycle of the PWM signal output to the diaphragm pump drive circuit from 50% to a maximum of 95% (corresponding to the maximum flow rate). When the power stabilizes, the PWM duty cycle automatically drops back to 30%-40% to maintain the speed, achieving quiet operation and energy saving.

[0083] Lifespan reminder: A built-in timer in the microcontroller accumulates the operating time of the diaphragm pump. When the accumulated operation reaches 50 hours (approximately equivalent to the filter element's saturation life), an icon prompting "Please replace the filter element" will be displayed on the OLED screen driven by the main control board 2.

[0084] 4. Equipment operation process and effects.

[0085] When a user picks up a soldering iron to solder; Instant response: The diaphragm pump starts almost simultaneously (delay <100ms) the moment the soldering iron tip is powered on and heated, forming a stable negative pressure flow field above the solder joint.

[0086] Highly efficient capture: The generated smoke is captured by the annular air intake at 12mm before it diffuses, with a measured capture efficiency of ≥96%.

[0087] Clean emissions: Smoke passes sequentially through a heat-resistant hose, a HEPA filter, and an activated carbon layer, effectively filtering particulate matter and harmful gases, and finally the clean air is discharged from the diaphragm pump outlet.

[0088] Intelligent energy saving: During welding intervals, the diaphragm pump automatically reduces to a low speed; after welding is completed and the soldering iron is placed down, the diaphragm pump automatically shuts off after removing residual fumes. The standby power consumption of the equipment is determined by the main control board, and the additional power consumption of the purification module is almost zero.

[0089] Quiet operation: The diaphragm pump operates at a drive frequency of 25kHz, which is perceived by the human ear as a slight airflow sound. After being isolated by the shell and absorbed by the sound-absorbing cotton, the noise level was measured at a distance of 30cm as 38dB(A).

[0090] This embodiment fully demonstrates how the present invention, through ingenious structural design, modular integration, and intelligent algorithms based on multi-sensor fusion, seamlessly integrates efficient smoke purification functions into an electric soldering iron, achieving excellent comprehensive performance in source capture, automatic operation, energy saving and low noise, and convenient maintenance.

[0091] Summary of the innovative points of this invention: 1. Innovative Structural Integration: The design integrates flue gas treatment with an electric soldering iron, pioneering a ring-shaped near-source air intake structure to achieve immediate capture of welding combustion products at the source; 2. Control collaborative innovation; based on a welding condition recognition algorithm using multi-sensor data fusion, adaptive linkage control between the flue gas treatment system and welding operation is achieved; 3. Compact design innovation; the integrated application of an 8cm³ miniaturized multi-stage filtration module and an ultra-thin diaphragm pump breaks through the contradiction between space constraints and purification efficiency; 4. Energy efficiency optimization and innovation; based on a dynamic power adjustment strategy that adjusts the power based on the intensity of combustion byproducts, a balance is achieved between ultra-low standby power consumption and high-efficiency purification. 5.

Thermal management innovation; the design of the heat-insulated airflow channel solves the problem of mutual interference between integrated flue gas treatment and welding temperature stability.

[0092] The comprehensive advantages of this invention are reflected in multiple dimensions such as environmental performance, space utilization, control precision, energy efficiency optimization, ease of use, and cost-effectiveness. It solves the technical problems existing in the prior art and provides an innovative intelligent and environmentally friendly solution for the field of electronic welding.
