Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes and smoking devices, and in particular to an electronic water pipe. Background Art

[0002] As a long-standing form of smoking, traditional hookah is mainly composed of a tobacco bowl, a charcoal fire layer, a water body in the pot, and a straw system. Its working principle is to heat the special tobacco (usually mixed with honey or syrup) in the top tobacco bowl through the charcoal fire layer, so that the tobacco releases steam with nicotine and fragrance. The steam flows through the metal tube into the water body of the pot and is filtered before being inhaled by the user through the straw. However, there are many inconveniences and health risks in the use of traditional hookah. First, the heating method of the charcoal fire layer is complicated to operate and inconvenient to carry; secondly, special tobacco or tobacco paste will produce tar during the combustion process, which will directly damage the alveoli and cilia, increasing the risk of lung cancer; in addition, because tobacco is mixed with a variety of spices, high-temperature decomposition may produce unknown toxic substances, further endangering human health.

[0003] Electronic cigarettes are mainly composed of components such as e-liquid, heating system, and power supply. They produce aerosols with a specific smell through heating and atomization for smokers to use. Although electronic cigarettes do not contain tar, they still contain many other carcinogens.

DETAILED DESCRIPTION

[0056] The present invention provides an electronic hookah, which adopts a modular structure design and has detachable connections between components, which is not only convenient for daily maintenance and cleaning, but also supports a variety of cigarette cartridges. At the same time, the device is equipped with interesting interactive functions to effectively enhance the user experience. Figure 1 To the attached Figure 29 , the specific implementation methods of the present invention are described in detail.

[0057] From an overall structural perspective, this electronic hookah consists of two main components: the cigarette cartridge and the main unit. The main unit includes the cigarette cartridge holder 16, the cigarette tube holder 17, the main unit housing, the battery assembly 35, the control panel 38, the straight tube 24, the filter device 37, the straw assembly 18, and other core components. These components are assembled using a scientific and rational detachable connection method, greatly facilitating user maintenance and cleaning.

[0058] The cartridge 2, also known as the e-cigarette atomizer (or e-liquid cartridge), is the core consumable component of the e-cigarette. It contains e-liquid (i.e., e-cigarette liquid) and integrates a heating element and a cotton wick. When the cartridge 2 is connected to the e-cigarette host, the host controls the heating element to heat the e-liquid inside, causing it to atomize and produce a vapor for inhalation. The cartridge 2 can be divided into two types based on usage: disposable cartridges and replaceable cartridges (refillable). Replacing the cartridge 2 allows for easy switching of flavors or nicotine concentrations, which is both convenient and hygienic.

[0059] The electronic cigarette main unit acts as the "heart" of the entire device, primarily responsible for providing power to the cigarette cartridge 2 and intelligently controlling the entire electronic cigarette's operation. Building on the functions of traditional electronic cigarette main units, this invention innovatively incorporates the filtering capabilities of traditional hookahs. The smoke generated by the atomization of the cigarette cartridge 2 is transported through internal pipes within the main unit to the filter device 37. The filtered smoke is then inhaled by the user, effectively reducing the harmful effects of the smoke on the user's health.

[0060] In this embodiment, the cigarette cartridge 2 specifically includes an upper cover 201, a cigarette cartridge shell 203, a cigarette cartridge base 15, a heating component, an oil storage chamber 204, and an oil storage cotton 10. The upper cover 201 is provided with an air inlet 202 and is detachably connected to the cigarette cartridge shell 203, which is convenient for users to add smoke oil. The heating component integrated in the middle of the cigarette cartridge shell 203 is a key part for realizing the atomization of smoke oil. It consists of an atomization tube 5, and an oil storage cotton 10 arranged in the atomization tube 5 in sequence and a heating wire finished core 8 sleeved in the oil storage cotton 10. A number of oil immersion through holes 501 are provided on the side of the atomization tube 5 to ensure that the smoke oil can be smoothly immersed into the oil storage cotton 10 from the oil storage chamber. The finished heating wire core 8 is preferably a resistance wire connected to the positive and negative conductive terminals 801. When current flows through, the resistance wire generates heat due to its own resistance, heating the tobacco oil on the oil storage cotton 10 to the atomization temperature. Generally, the tobacco oil can achieve the atomization effect when the temperature reaches the range of 200-350°C, thereby generating smoke or steam for the user to inhale. An oil storage chamber 204 is formed between the cigarette cartridge shell 203 and the atomization tube 5 for storing tobacco oil. An oil filling hole 301 is provided on the top of the cigarette cartridge shell 203 near the upper cover 201, through which the user can add tobacco oil to the oil storage chamber 204; to prevent tobacco oil leakage, an oil filling plug 3 is also specially provided on the oil filling hole. An annular groove 502 is provided at the top of the atomization tube 5. At the connection between the atomization tube 5 and the cigarette cartridge shell 203, an atomization tube sealing ring 9 that matches the annular groove 502 is provided to effectively prevent tobacco oil from overflowing from the oil storage chamber 204. To further prevent the oil in the oil storage chamber 204 from overflowing from the bottom, a silicone baffle 7 is installed at the bottom of the oil storage chamber 204. Below the silicone baffle 7 is a silicone annular oil cup plug 6. Together with the cartridge housing 203 and the heating element 18, the annular oil cup plug 6 forms a sealed oil storage chamber. The annular oil cup plug 6 also provides insulation and blocks the oil in the oil storage chamber 204 from flowing into the oil storage cotton 10, ensuring that the heating wire only heats the oil on the oil storage cotton 10 in the atomizer tube 5. Because the heating element needs to penetrate the cartridge housing 203 to form an air inlet channel, a matching air inlet hole 205 is provided at the top of the cartridge housing 203, and a smoke hole is provided at the bottom to facilitate connection with the electronic cigarette host. The heating component is fixed on the cigarette cartridge base 15 set below, and a heating wire fixing seat 11 is provided on the base. A cigarette cartridge heating wire silicone 12 is provided in the middle where the heating wire fixing seat 11 is connected to the cigarette cartridge base 15, and a groove is provided in the middle to match the lower end of the heating component, as well as a through hole for the passage of atomized smoke and the positive and negative conductive terminals 801.

[0061] The cigarette cartridge base 15 is movably connected to the cigarette cartridge shell 203, and the cigarette cartridge shell is provided with a process space 208. To avoid leakage of smoke oil, the annular oil cup plug 6 is used to block the through holes 501 distributed on the side of the atomizer tube 5 before use to prevent the smoke oil from seeping into the oil storage cotton 10; further, the smoke oil in the oil storage chamber is allowed to seep into the oil storage cotton during use. When in use, the cigarette cartridge base is used to push the heating component to move toward the top. When the through holes 501 distributed on the side of the atomizer tube 5 move to the oil storage chamber 204, the smoke oil can be seeped into the oil storage cotton 10 through the through holes 501 on the atomizer tube.

[0062] Specifically, a protruding slider 151 is symmetrically provided on the side of the cigarette cartridge base 15, and a spherical marble 152 is set on the slider for limiting the position; a slide groove 206 matching the slider 151 is provided in the cigarette cartridge shell, and at least two card slots for matching and fixing the spherical marble are provided on the slide groove; to further enhance stability, protruding limiting columns 153 are symmetrically provided on the side of the cigarette cartridge base, and are distributed on the side of the cigarette cartridge base at intervals with the slider 151, and a limiting column groove 207 matching the limiting column 153 is provided in the cigarette cartridge shell. Before use, the cartridge base is fixed to the cartridge housing via the spherical marble 152. A reserved heating component process space 208 is formed between the annular oil cup plug 6 and the heating wire fixing seat. At this time, the through hole 501 distributed on the side of the atomizer tube 5 is blocked by the annular oil cup plug 6, and the smoke liquid cannot penetrate the oil storage cotton. During use, an upward thrust is applied to the cartridge base to push the heating component to move. The spherical marble 152 on the cartridge base is forced to move from the initial position to the target position and re-fixed on the cartridge housing. The heating component process space 208 is squeezed by the cartridge base, pushing the heating component to move toward the top. At this time, the through hole 501 distributed on the side of the atomizer tube 5 is connected to the oil storage chamber, allowing the smoke liquid to penetrate the oil storage cotton. The cartridge base 15 and the heating wire silicone 12 are fixed by fixing screws 154. The fixing screws 154 pass through the cartridge base 15 to fix the cartridge heating wire silicone 12. To prevent the leakage of electronic cigarette smoke, oil-absorbing cotton 13 is further provided under the heating wire silicone 12 to prevent the leakage of smoke oil. In order to achieve the detachable fixation of the cigarette cartridge 2 on the host, this design preferably uses the principle of magnetic attraction and sets a magnet 155 on the cigarette cartridge base 15. The specific method is to open a corresponding groove on the cigarette cartridge base 15, embed the magnet 155 into the groove and fix it, and cooperate with the magnet on the host to achieve a convenient detachable connection, which is convenient for users to replace the cigarette cartridge 2 at any time. During transportation or when the equipment is out of use, in order to prevent dust from entering from the air inlet 202 of the upper cover, a cigarette cartridge dustproof sticker 1 is provided on the upper cover 201, which can be torn off when used; of course, it can also be set as a cover according to actual needs. The cigarette cartridge 2 in this embodiment is designed to be a cylindrical structure to adapt to the overall structure of the host. Similarly, other shapes that match the host interface design can be used. By opening an oil filling hole 301, it becomes a replaceable cigarette cartridge (refuelable) type; if there is a need to simplify the design, the detachable structure of the oil filling hole 301 and the upper cover 201 can also be cancelled, and it can be made into a disposable cigarette cartridge using an integrated molding process.

[0063] The main function of the cigarette cartridge holder 16 is to fix the cigarette cartridge, and in combination with the internal integrated control board, provide power and light source feedback to the cigarette cartridge. The overall shape is a trumpet copper bell, with a housing cavity for matching the cigarette cartridge 2 inside, and a cigarette cartridge pipe 162 connected to the inside of the cigarette cartridge at the bottom. One end 164 of the cigarette cartridge pipe receives the atomized smoke from the cigarette cartridge and outputs it through the other end 163 of the cigarette cartridge pipe, and the cigarette cartridge pipe is provided with screw threads at the end. The cigarette cartridge holder is also provided with a control board (PCBA), a cigarette cartridge light board 4, a sealing silicone 14 for the smoke guide pipe to achieve a sealing effect, and a light-transmitting part 161. The cigarette cartridge light board 4 integrates a light source - LED lamp beads 401, and protruding positive and negative electrodes 402. The lamp beads are arranged in a ring around the lamp board. The protruding positive and negative electrodes 402 are connected to the positive and negative conductive terminals 801 at the bottom of the cigarette cartridge 2 to ensure the stability of the electrical connection. The cigarette cartridge light board 4 is installed at the bottom of the housing cavity. The cigarette duct sealing silicone 14 is set above the cigarette cartridge light board 4, and is also provided with a through hole that matches the cigarette cartridge light board 4, and is inlaid with a magnet (or metal) 403, which is used to cooperate with the magnet 155 at the bottom of the cigarette cartridge 2 to achieve magnetic fixation and ensure that the cigarette cartridge 2 is firmly connected. The light-transmitting member 161 is set on the cigarette duct sealing silicone 14, and is also provided with a matching through hole. It is made of transparent material and installed inside the accommodating cavity to accommodate the cigarette cartridge 2. When the light source LED lamp bead 401 emits light, the light can pass through the light-transmitting member 161 and emit from the top of the cigarette cartridge holder 16 to the surrounding area, providing the user with an intuitive display of the cigarette cartridge working status and serving as an atmosphere light to enhance the fun. The coordination process between the cigarette cartridge holder 16 and the cigarette cartridge 2 is as follows: when the user uses it, the cigarette cartridge 2 is inserted into the accommodating cavity of the cigarette cartridge holder 16 with the bottom facing down, and the magnets at the bottom of the cigarette cartridge 2 and the accommodating cavity are attracted to each other to achieve fixation. At the same time, the positive and negative conductive ends at the bottom of the cigarette cartridge 2 are connected to the positive and negative electrodes 402 in the accommodating cavity to complete the electrical connection. The MCU integrated into the control board 38 intelligently controls the entire process. Upon detecting the cigarette cartridge 2, the control board (PCBA) cartridge light board 4 controls the LEDs to emit light signals of varying colors and brightness based on pre-set logic. The light is then transmitted through the light-transmitting element and scattered toward the top, not only alerting the user to the operating status of the cigarette cartridge 2 but also enhancing the overall product ambiance and user enjoyment. Furthermore, the cigarette cartridge holder 16 is provided with a pipe for the atomized airflow, through which the smoke generated by the atomization of the cigarette cartridge 2 can be smoothly transported.

[0064] The pipe holder 17 primarily houses and secures the straw assembly. It is located at the bottom of the cartridge holder 16 and is connected to the main unit. It features a pipe holder annular sleeve 172, ensuring smooth passage of the pipe within the chamber. A side-mounted pipe holder slot 171 secures the straw assembly 18, ensuring its secure installation. The pipe holder primarily houses and secures the straw assembly, making it easy for the user to remove the straw from the slot. Alternatively, the pipe holder can be eliminated, with the slot 171 located directly on the side of the cartridge holder or main unit housing.

[0065] The main body shell is composed of an outer shell 36 and a battery fixing bracket 25. The outer shell 36 is trumpet-shaped as a whole, and a smoke airflow pipe is provided inside. The upper and middle ends are thinner, and the diameter of the middle and lower parts gradually increases. A shell pipe interface 361 is provided on the top of the outer shell 36, and an internal thread is provided at the interface, which can be detachably connected to the external thread of the cartridge holder pipe 162, and is used to receive the atomized smoke (airflow) from the other end 163 of the cartridge pipe and output it from the other end of the outer shell pipe interface 361. The battery fixing bracket 25 includes an opening 363 arranged in the center, and the battery pipe interface 364 is connected to the outer shell pipe interface 361. A U-shaped base 362 for accommodating the battery assembly 35 is provided on the bottom side of the battery fixing bracket 25. A groove is provided on the side of the outer shell 36, and the battery fixing bracket 25 is fixed in the groove, and the base 362 is exposed outside the groove. Magnets and buckles are provided in the base 362 for firmly fixing the battery assembly 35. The battery fixing bracket 25 is also provided with a power button 27 and a light guide bar 28, and the housing 36 is provided with corresponding through holes to ensure that the installation position of each component is accurate and the function is normal.

[0066] The battery assembly 35 in this solution adopts a detachable modular design, including a charging port 351 and a power status indicator 352 on the surface of the housing. A battery is housed inside the housing and can be charged through the charging port. To facilitate disassembly, anti-slip pads 353 are provided on both sides. Furthermore, a magnet 355 is provided that fits on the base 362, and a groove 354 that matches the pipe inside the battery mounting bracket 25 ensures that the battery assembly 35 is securely installed and easy to remove and replace. The overall shape of the battery assembly 35 matches the U-shaped base 362 design, and the magnetic principle is used to achieve a detachable connection, allowing users to quickly replace spare batteries.

[0067] The control board 38 is fixed within the main body housing. Specifically, it is located at the bottom of the battery mounting bracket 25 and is electrically connected to the cartridge holder 16, battery assembly 35, power button 27, and light guide strip 28. The airflow sensor integrated on the control board 38 is one of the key components for the device to achieve intelligent control. It uses a silicon-based airflow monitoring sensor (MSPC01-GDLS35). When the airflow sensor detects airflow in the pipe, it converts it into an electrical signal and sends it to the control board 38. The control board's main control MCU controls the input of high-voltage current to the cartridge 2 based on this electrical signal, thereby achieving the atomization effect of the e-liquid. At the same time, the main control MCU controls the remaining circuits to complete their respective tasks.

[0068] The function of the straight tube 24 is to connect the smoke generated by the cigarette cartridge through the cigarette cartridge holder to the smoke duct inside the main body housing. The internal smoke duct is connected to the straight tube and transports the smoke to the filter device 37. Specifically, one end of the straight tube 24 is connected to the duct inside the battery fixing bracket 25, and the other end is detachably connected to the one-way flow smoke pipe 30 inside the filter device 37. The one-way flow smoke pipe 30 is equipped with a one-way valve at one end near the filter device 37, which only allows one-way flow of smoke. The valve includes a floating bead 31, a smoke pipe plug 32, and a through hole on the side of the end. Under normal pressure, the floating bead 31 rises due to buoyancy and blocks the pipe, effectively preventing liquid in the filter device container from entering the pipe. When the smoke holding chamber 371 is under negative pressure, the floating bead 31 is sucked down, and the smoke is discharged into the liquid through the through hole on the side. The smoke pipe plug 32 is used to block the end of the one-way flow smoke pipe, restricting the flow of liquid into the pipe and preventing the floating bead 31 from being misplaced, ensuring the normal operation of the one-way flow smoke pipe.

[0069] The filter device is primarily used to improve the inhalation experience, reduce the intake of harmful substances, or enhance the taste. In this embodiment, a water filter device is incorporated, incorporating the principles of traditional hookah filtration. Its purpose is to physically filter and cool the smoke generated by the e-cigarette through water, improving the inhalation experience and removing some impurities. In this embodiment, water is used as the primary filtration medium. The filter device 37 is essentially a container for storing liquid, and can be made of glass. Liquid (such as water) can be added to the container, and other materials, such as activated carbon, can also be added depending on the harmful substances in the smoke to achieve better filtration. Adding ice cubes can also improve the taste of the smoke, for example. When the atomized smoke passes through the filter device, it effectively removes some harmful substances from the smoke before it is available for inhalation. The filtered water enhances the e-cigarette experience, improves the taste, cools the smoke, and captures most particulate impurities. The filter device includes a glass container for holding the liquid. The transparent glass material facilitates observation of the internal liquid and smoke filtration status. The glass container is equipped with a snap fastener for detachable connection to the bottom of the main body shell. For aesthetic purposes, the surface of the glass container is also decorated with a diamond pattern. When in use, two-thirds of the glass tank is filled with pure water. When it is fixed on the main unit, the straight one-way flow smoke pipe 30 on the main unit is submerged in the pure water, and the smoke is sucked into the pure water, and then emerges from the water and is temporarily stored in the smoke receiving chamber.

[0070] The filter device 37 is removably fixed to the bottom of the main housing. The main housing is equipped with a liner 26 and a sealing ring 33, an internal interface for securing the filter device 37 container, and a container sealing ring 33 that fits over the liner interface. The interface between the filter device and the liner is removably connected, and the sealing ring 33 inside the interface ensures a tight connection between the filter device 37 and the main housing, preventing smoke leakage. When the filter device 37 is connected to the main housing, a sealed smoke chamber 371 is formed, which is used to temporarily store filtered smoke. The interface between the main housing and the filter device 37 is equipped with a gas guide plug 29 for unidirectionally discharging the smoke chamber 371 and an elastic clip 23 for connecting the straw assembly. To facilitate the user's emptying of the smoke temporarily stored in the smoke chamber, the end of the smoke guide plug 29 is equipped with a one-way valve seat 34. Its unique structural design only allows gas to flow in a fixed direction and prevents reverse flow. In this embodiment, when the user needs to expel smoke from the smoke chamber 371, they simply turn off the power and reversely pressurize (blow air) the chamber 371 through the suction tube assembly. The smoke will then be smoothly expelled from the smoke guide plug 29. The elastic clip 23 is connected to the hose connector 211, which is connected to the hose, allowing the user to inhale the filtered smoke temporarily stored in the smoke chamber. The elastic clip 23 also has an airflow monitoring sensor 231 integrated into the control board at the end of the smoke chamber to detect the airflow within the pipe and provide feedback to the control board.

[0071] The following are experimental test results for filter device 37, testing the changes in the content of harmful substances such as particulate matter, nicotine, and formaldehyde in the e-cigarette smoke before and after passing through the filter device, as well as the improvement in the user's inhalation experience and taste.

[0072] Test items Unfiltered (mean) After water filtration (average) Improvement rate / change <![CDATA[Particulate matter (μg / m 3 )]]> 120 35 ↓71％ <![CDATA[Nicotine (mg / m 3 )]]> 2.5 1.7 ↓32％ <![CDATA[Formaldehyde (mg / m 3 )]]> 0.18 0.09 ↓50％ Smoke temperature (℃) 38 26 ↓12℃ Taste rating (1-10) 5.2 8.3 ↑59％ Stimulation score (1-10) 6.8 3.1 ↓54％

[0073] The experimental method involved collecting e-cigarette smoke samples, both unfiltered and filtered, and analyzing them using instruments such as a particle detector and gas chromatograph. Ten volunteers were then invited to provide subjective experience ratings. Volunteers generally reported that the filtered smoke was significantly cooler, had a softer taste, less irritation, and a more comfortable inhalation experience. The transparent glass tank facilitates observation of the filtering effect and enhances the overall aesthetics. In summary, the filtration device can effectively reduce the content of harmful substances such as particulate matter, nicotine, and formaldehyde in e-cigarette smoke, significantly improving the inhalation experience and taste, and enhancing product safety and user satisfaction.

[0074] The straw assembly 18 includes a hose 21 and a metal tube 20 connected to the hose 21. One end of the hose 21 is connected to a hose connector 211, with a snap fastener for easy removal. The other end is connected to the metal tube 20. The metal tube 20 is equipped with a non-slip grip 22 and a nozzle head 19 for user convenience. It's worth noting that multiple straw assemblies 18 can be configured as needed. Simply by providing multiple matching through-holes in the main body housing near the smoke chamber 371, multiple straw assemblies 18 can be connected, allowing for simultaneous use by multiple people.

[0075] like Figures 25 to 29 The figure shows the schematic diagram of the electronic cigarette control circuit in this scheme, which mainly includes the main control MCU control unit, power management unit, cigarette cartridge control unit, cigarette cartridge light board control unit, and inhalation detection unit.

[0076] The main control MCU uses a PY32C642F15U6-C microcontroller, serving as the core control unit of the e-cigarette motherboard. This chip receives 5V power from the VDD pin, which is filtered by resistors and capacitors to ensure stable power supply. The MCU is responsible for detecting user keystrokes and inhalation. Signals from the K1 button and the airflow sensor are connected to the PB7 pin via a resistor, enabling real-time response to user actions. The main control chip also collects battery and output voltages via a voltage divider resistor and feeds them into the BAT_AD and OUT_AD pins for ADC sampling, enabling monitoring of battery charge and output status. The chip's multiple IO ports are also used to control peripherals such as cartridge 2, the cartridge holder LED, and the buzzer. For example, PCL1 is used to turn cartridge 2 on and off, while HC1 and HC2 indicate the status of the cartridge holder LED or buzzer. The main control also features a microphone input for collecting audio signals for intelligent functions such as inhalation detection. Overall, the main control MCU, through input signal acquisition and peripheral control, implements the basic functions of the e-cigarette and multiple safety measures, ensuring device stability and user safety.

[0077] The power management unit (PMU) uses batteries (BAT1 and BAT2) as its energy source, with VBAT serving as the main power input. Large-capacity capacitors such as C1 (220μF / 10V), C4 (4.7μF), and C5 (4.7μF) provide input and output filtering to suppress power supply noise and voltage fluctuations. U1 (HT7550-1), a low-dropout linear voltage regulator, regulates VBAT to a 5V output, powering the main MCU and other low-voltage modules. MOS transistors Q1 and Q2 (such as the RHMN7421 or RHMN2700K) work with D1 and D2 (1N5819 Schottky diodes) to form the main power switching circuit, controlling the atomizer's on / off state. R1, R2, R3, R4, and R5 serve as voltage divider and current-limiting resistors, providing both voltage sampling and protection for downstream circuitry. F1 is a 5A / 40V fuse to prevent overcurrent damage. Capacitors such as C2, C3, C6, C7, and C8 are distributed at key nodes to further improve the stability and anti-interference capability of the power supply.

[0078] The cartridge control unit primarily consists of MOSFETs Q1 and Q2, Schottky diodes D1 and D2, voltage divider resistors R1 and R5, and fuse F1. The main MCU outputs a control signal through pin PCL1, turning the MOSFETs on and off, thereby controlling the atomizer's heating. D1 and D2 prevent reverse current flow and protect the circuit. R1 and R5 are used for current detection and voltage sampling, while fuse F1 provides overcurrent protection for the atomizer, preventing damage to the atomizer or motherboard under abnormal conditions.

[0079] The control unit for the cartridge light board is the schematic diagram of the control circuit for the cartridge holder and light board 4 in this solution. It uses the 3528RGB 2815B chip, a mainstream intelligent RGB LED control chip. Each component uses decoupling capacitors (such as C17, C18, C19, and C20) to filter power supply noise. It is powered by a 5V power supply. The LED control signal is input from "HC2_YDLED," which cascades and drives multiple 2815B chips to achieve series control of multiple LED lights. "HC2_YDLED" is the digital control signal sent from the main control board and connected to the first 2815B chip (HC16). The DO (data output) of each 2815B chip is connected to the DI (data input) of the next chip, forming a complete data link. The main control board controls the color and on / off of each LED via the power and data lines, achieving a colorful display and status feedback for the LED lights on the cartridge light board 4 on the cartridge holder. For example: when the user inserts or removes the cigarette cartridge, the LED light uses different lighting effects to prompt the user whether the operation is successful; when the user smokes, the light strip lights up or produces a breathing light effect, increasing the product's sense of technology and user experience; when the battery is low or the cigarette cartridge fails, the LED light flashes in different colors to warn, etc., which can be controlled by the main control board to achieve diverse changes in light color, brightness, and dynamic effects.

[0080] The inhalation detection unit includes components such as an airflow sensor interface (PDA), button K1, and a microphone (MIC). The airflow sensor signal is connected to the MCU's PB7 pin via R14 (10Ω), and button K1 is similarly connected to PB7, enabling detection of the user's inhalation and button presses. The microphone signal is connected to the MCU's MIC pin via R15 (100K). The main control MCU can further determine inhalation by collecting sound signals. Through these detection methods, the main control MCU can accurately identify the user's smoking behavior, implementing intelligent start-stop and safety control.

[0081] Overall, this circuit realizes the core functions of the electronic cigarette host, such as power supply management, intelligent control, atomization control by cigarette cartridges, light prompts and inhalation detection, through the coordinated work of various modules, and ensures the safety and reliability of the equipment through multiple protection measures.

[0082] The working principle is as follows: First, the user injects an appropriate amount of tobacco oil into the cigarette cartridge 2 through the oil filling plug 3 and inserts the cigarette cartridge into the cigarette cartridge base 15 on the top of the main unit, and adds pure water and activated carbon to the filter device. When the user presses the power button 27 to start the device, the control main board will immediately detect the status of the cigarette cartridge 2, and trigger the cigarette cartridge light board 4 to light up the LED lamp bead 401. The light passes through the light-transmitting part 161 to feedback the status of the cigarette cartridge 2, allowing the user to understand the working status of the cigarette cartridge at the first time. The user inhales through the mouthpiece 19, and the airflow passes through the straw assembly in turn. The airflow monitoring sensor 231 set in the elastic buckle 23 detects the airflow and transmits the signal to the control board. The main control MCU accurately recognizes the user's inhalation action and drives the cigarette cartridge 2 heating component to atomize the tobacco oil on the oil storage cotton into smoke. At the same time, a negative pressure is generated in the smoke holding chamber 371, and the negative pressure pushes the floating water beads 31 in the one-way flow tube 30 to descend, thereby opening the channel to connect with the cigarette cartridge. Air is smoothly drawn into the pipe through the air inlet at the top of the cartridge. The smoke generated by the cartridge 2 is connected to the cartridge holder at the bottom. The cartridge holder, main body housing, battery mounting bracket, and straight tube together form a smoke pipe connected to the cartridge. The atomized smoke from the cartridge 2 is transported through the smoke pipe to the filter device 37 for filtration. The filtered smoke is temporarily stored in the smoke holding chamber and is then inhaled by the user through the straw assembly. During device operation, the main control unit (MUC) adjusts the light color, brightness, and dynamic effects based on the status of the cartridge through the cartridge light board control unit, providing intuitive signal feedback and interaction to the user. The light guide bar 28 adjusts the light color in real time based on the remaining battery power, allowing the user to keep track of the device's power level. After use, the user can easily remove various components for cleaning or replacement. For example, the filter device 37 can be removed to clean the interior of the glass jar and the straight tube, or the cartridge 2 can be removed from the cartridge holder 16 for maintenance. Furthermore, the snap-on detachable battery assembly 35 allows for quick replacement, allowing users to continue using the device without having to wait for a long time for charging, greatly improving user convenience.

[0083] To sum up, the structural design of the present invention is modular and the components are detachably connected, which is convenient for users to maintain and clean; the cigarette cartridge 2 allows users to change flavors or nicotine concentrations, and is convenient and hygienic to use; the cigarette cartridge holder fixes the cigarette cartridge through magnetic attraction and uses LED light beads to display the cigarette cartridge status, thereby enhancing the overall atmosphere and fun of the product; the host is combined with a filtering function to reduce the harm of smoke to the user's body; the light guide bar adjusts the light color in real time according to the remaining battery power, providing users with intuitive power feedback; the snap-on detachable battery assembly supports quick replacement, and users can continue to use it without waiting for a long time to charge; multiple sets of straw assemblies can be set up to meet the needs of multiple people at the same time.
