Description

Technical Field

[0001] This utility model relates to the field of smoke generating devices, and in particular to an automated smoke generating system that supports WiFi networking. Background Technology

[0002] A smoke generator is a device that produces smoke or mist, widely used in various scenarios such as stage performances, agricultural pest control, fire drills, film and television shooting, and industrial testing. Currently, widely used smoke generators capable of continuously spraying smoke for over an hour primarily rely on external power supplies, which limits their outdoor use. Furthermore, their large size and weight make them inconvenient to move. On the other hand, while portable small smoke generators are easy to carry, their continuous working time is short, typically less than 15 minutes, the smoke distribution is uneven, and they are prone to oil spillage, further shortening the effective working time, and the amount of smoke produced is relatively small.

[0003] Meanwhile, traditional fogging machines mostly use wired control or simple remote control methods, which suffer from limited control distance, limited functionality, and inability to monitor device status in real time. While some existing fogging machines support temperature adjustment, they lack precise temperature control algorithms and fault protection mechanisms, making them prone to safety hazards due to overheating or insufficient e-liquid. Furthermore, most devices lack integrated IoT functionality, hindering remote monitoring and intelligent management. Therefore, a new and convenient fogging device is urgently needed to solve these problems. Utility Model Content

However, this should not be construed as limiting the scope of protection of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an automated smoke generation system supporting WiFi networking, including a housing 1, a liquid inlet 2, a reset button 3, a power switch and indicator light button 4, a peristaltic pump 5, an oil tank 6, an atomizing assembly 10, and a smoke outlet 12. It also includes a lithium battery pack 7, a main control board 8, a multi-point photoelectric liquid level sensor 9, and heat insulation cotton 11.

[0028] The peristaltic pump 5, the e-liquid tank 6, the lithium battery pack 7 and the main control board 8 are fixedly installed inside the housing 1;

[0029] The e-liquid tank 6 is fixedly equipped with a multi-point photoelectric liquid level sensor 9, and more than two monitoring points are preset to detect different liquid level thresholds.

[0030] The atomizing component 10 consists of a heating rod 1001, an atomizing spiral tube 1002, and a K-type thermocouple 1003. The heating rod 1001 is embedded in the atomizing spiral tube 1002, and the K-type thermocouple 1003 is attached to the surface of the atomizing spiral tube 1002. The atomizing component 10 is also wrapped with heat insulation cotton 11.

[0031] The e-liquid tank 6 is equipped with a flexible hose that extends to the inlet end of the peristaltic pump 5. The outlet end of the peristaltic pump 5 is connected to the atomizing spiral tube 1002 through the flexible hose, forming a smoke generation channel.

[0032] The upper end of the outer wall of the housing 1 is provided with a smoke outlet 12, and the smoke outlet 12 is fixedly connected to an atomizing spiral tube 1002 to form a smoke exhaust channel.

[0033] The main control board 8 is communicatively connected to the reset button 3, the switch and indicator light button 4, the peristaltic pump 5, the multi-point photoelectric liquid level sensor 9, the heating rod 1001, and the K-type thermocouple 1003.

[0034] The main control board 8 is used to receive real-time temperature signals from the K-type thermocouple 1003 and output power control commands to the heating rod 1001.

[0035] The main control board 8 is also used to receive the liquid level status signal from the photoelectric liquid level sensor 9 and output flow control commands to the peristaltic pump 5.

[0036] The main control board 8 is also used to receive key signals from the switch and indicator light key 4 and issue indicator light output status display instructions;

[0037] The main control board 8 is also used to receive operation command signals from smart devices and output switch, smoke generation and flow control commands.

[0038] The core component of the main control board 8 is the ESP32 chip. GPIO pins are evenly arranged around the ESP32 chip. The main control board 8 controls the operation of the entire device and interacts with the server and mobile phone through the built-in communication unit via the GPIO pins.

[0039] The ESP32 chip, developed by Espressif Systems, is a high-performance, low-power, and highly integrated Wi-Fi & Bluetooth dual-mode IoT chip widely used in smart homes, industrial control, wearable devices, and other fields. In this device, the ESP32 chip integrates a Wi-Fi control unit and an MQTT service node, used for connecting to a mobile phone via Wi-Fi and interacting with a server via the MQTT protocol.

[0040] The main control board 8 is designed with multiple functional areas, each executing different instructions. These functional areas include: a control area, which includes WiFi communication control, multi-sensor collaboration, and actuator driving; a power management and distribution area, which includes power management and distribution, multi-voltage domain power supply, and power consumption optimization; a safety protection mechanism area, which includes over-temperature protection, liquid level sensing, and short-circuit protection; and a user interaction interface area, which includes physical button control and status indicator control.

[0041] GPIO (General Purpose Input / Output) is a general purpose input / output pin, which is one of the core interfaces for microcontrollers to interact with external devices. It has programmable control and multi-functional multiplexing characteristics.

[0042] Furthermore, the multi-point photoelectric liquid level sensor 9 is fixedly mounted on the e-liquid tank 6, with the probe end of the multi-point photoelectric liquid level sensor 9 extending vertically into the interior of the e-liquid tank 6, and the signal output end fixedly mounted on the upper surface of the exterior of the e-liquid tank 6; the signal output end of the multi-point photoelectric liquid level sensor 9 communicates with the main control board 8 through an I2C interface for feedback of liquid level signals.

[0043] I2C is a widely used synchronous, multi-master, serial communication bus protocol suitable for short-distance, low-speed communication between devices such as sensors, EEPROMs, and displays.

[0044] Furthermore, the upper surface of the housing 1 is provided with an inlet 2 opening, which extends vertically into the interior of the housing 1; the upper surface of the housing 1 is also provided with a reset button 3 and a switch and indicator light button 4.

[0045] Furthermore, the atomizing component 10 is horizontally fixed to the upper end of the inner wall of the housing 1.

[0046] Furthermore, the lithium battery pack 7 is electrically connected to the reset button 3, the switch and indicator light button 4, the peristaltic pump 5, the main control board 8, the multi-point photoelectric liquid level sensor 9, and the atomizing component 10.

[0047] In this invention, the smoke generation has three modes: low, medium, and high. The heating rod 1001 has three heating powers: 20W, 40W, and 60W, which correspond one-to-one with the three flow rates of the peristaltic pump 5: 0.5ml / min, 1ml / min, and 1.5ml / min. The power and flow rate of the atomized smoke are controlled by the PWM signal output from the main control board 8, which controls the heating rod 1001 and the peristaltic pump 5.

[0048] The indicator light on switch and indicator light button 4 has six colors: red, green, yellow, blue, orange, and white.

[0049] Multi-color LED indicators display the device status (e.g., solid red indicates no network connection, flashing green indicates charging). The state machine logic supports 10 state transitions (e.g., normal standby, emitting smoke, device malfunction, etc.), ensuring users can intuitively understand the device's operating status.

[0050] In this utility model, according to its function, it can be divided into multiple functional modules, each executing different commands. These are:

[0051] The core control function module, with the main control board 8 as its core component, is used to control the operation of the entire device and communicate with the mobile phone.

[0052] The power and heating module consists of a peristaltic pump 5 and a heating rod 1001, and its function is to extract, heat, and generate smoke from the e-liquid.

[0053] The sensing module consists of a K-type thermocouple 1003 and a multi-point photoelectric liquid level sensor 9, and its function is to detect the e-liquid liquid level data and atomization temperature.

[0054] The human-computer interaction module consists of a reset button 3 and a power switch and indicator light button 4. Its function is to power on / off, reset, and display the working status.

[0055] The power module, consisting of a lithium battery pack 7, supplies power to the entire device and integrates overcurrent, overvoltage, and short-circuit protection circuits. These functions are performed by chips located within the battery, which is common knowledge in the field and will not be elaborated upon further.

[0056] The working process of the device of this utility model is as follows:

[0057] Press and hold the power button for 3 seconds to turn on the device. After powering on, the ESP32 chip inside the device will automatically connect to WiFi and enter standby mode.

[0058] Users can select the smoke emission mode (divided into three levels: large, medium, and small) through the backend, web page, or mobile APP. The device will then perform the corresponding operation according to the instructions and provide feedback on the status.

[0059] At the device end, after power-on, it first enters the preheating stage. The heating rod 1001 initially heats up to 200℃ at a power of 60W. If the waiting time for smoke emission is too long and the temperature inside the atomizing spiral tube 1002 drops below the target temperature, the core control module automatically switches the power of the heating rod 1001 to 20W for cyclic preheating. During the smoke emission stage, the core control module controls the peristaltic pump 5 to extract e-liquid from the e-liquid tank 6 and deliver it to the atomizing spiral tube 1002. In the atomizing spiral tube 1002, it is heated and atomized by the heating rod 1001. The atomized smoke is then discharged through the smoke outlet 12, completing the smoke generation process. Throughout the smoke atomization process, the core control module dynamically adjusts the heating power using a PID algorithm to maintain the temperature between 250℃ and 280℃ and ensures that the temperature fluctuation is ≤±5℃, thus enabling continuous smoke emission.

[0060] The K-type thermocouple 1003 is used to detect the atomization temperature. When the detected temperature is ≥300℃ for more than 20 seconds, it feeds the signal back to the core control module, which then controls a forced shutdown and triggers an alarm. The alarm can be triggered via a mobile app or by displaying a red indicator light. The multi-point photoelectric liquid level sensor 9 is used to detect the liquid level inside the e-liquid tank 6. When the liquid level is below 20%, it prompts the user to add e-liquid.

[0061] Under current technological conditions, while large smoke generators offer extended smoke production durations, their portability is limited by their reliance on fixed power sources, bulky size, and heavy weight. In contrast, existing small, portable smoke generators on the market generally produce smoke for no more than 15 minutes. Furthermore, current products lack devices capable of connecting to smart devices (such as mobile phones) via chips for intelligent control of smoke generation. This invention aims to fill this market gap by integrating Internet of Things (IoT) technology and adding rich human-computer interaction functions, thereby improving the convenience and efficiency of use.

[0062] This invention adopts an advanced modular hardware design concept. By highly integrating and optimizing the layout of various functional modules, the overall size of the smoke device is effectively reduced, making it lighter and more portable. Simultaneously, leveraging a high-performance ESP32 chip, the device successfully integrates advanced IoT technology, enabling not only remote control but also intelligent temperature control and switching between multiple smoke emission modes according to different needs, greatly enhancing its flexibility and practicality. This multifunctional smoke device is widely used in fire drills, stage special effects production, film and television shooting sets, and industrial testing, significantly expanding its application scenarios and meeting the diverse needs of different users. Furthermore, the device also features a built-in fault warning function, which can promptly issue alarms when abnormal conditions occur, further improving safety and reliability during use and providing users with more comprehensive safety protection.
