Description

Technical Field

[0001] This disclosure relates to the technical field of electronic cigarettes, and in particular to a regionally restricted electronic cigarette operating circuit and an electronic atomizer. Background Technology

[0002] With the increasing popularity of e-cigarette products and the growing demand for smoke-free environments in public places, traditional smoking bans relying on manual supervision or passive signage are no longer sufficient to meet the requirements of refined management. In special environments such as medical facilities, schools, gas stations, vehicles, or elevators, e-cigarette vapor may pose a potential threat to sensitive equipment, personnel health, or fire safety.

[0003] However, existing technological means (such as warning signs and manual patrols) have problems with regulatory blind spots and delayed implementation. Because manual patrols rely on personnel cooperation and consume a lot of human resources, and existing regulations lack the ability to punish those who violate the rules, smoking bans are difficult to implement efficiently, and may even lead to safety accidents due to loopholes in human management. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a regional restriction electronic cigarette operating circuit and electronic atomizer that automatically identifies no-smoking areas at the hardware level.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A regionally restricted electronic cigarette operating circuit includes a monitoring chip, a regional sensing module, and an atomization switch module. The regional sensing module receives an electromagnetic activation signal emitted by a reader via a wireless radio frequency tag embedded within it and outputs a sensing signal to the monitoring chip. The atomization switch module receives a control signal from the monitoring chip and controls the on / off state of the heating element power supply circuit according to the control signal. The sensing signal feedback terminal of the monitoring chip is connected to the sensing signal output terminal of the regional sensing module, and the control terminal of the atomization switch module is connected to the atomization signal control terminal of the monitoring chip.

The control terminal of the atomization control switch tube is connected to the atomization signal control terminal of the monitoring chip through the second current-limiting resistor.

[0011] In one embodiment, the atomization switch module further includes a first voltage divider resistor, the first end of which is connected to the battery power supply terminal, and the second end of which is connected to the first end of the atomization control switch tube.

[0012] In one embodiment, the atomization control switch is an NPN transistor.

[0013] In one embodiment, the area-restricted electronic cigarette operating circuit further includes an LED warning module, which includes a second voltage divider resistor and an LED light.

[0016] Compared with the prior art, this disclosure has at least the following advantages:

[0017] The aforementioned area-restricted e-cigarette operating circuit, through real-time interaction between a wireless radio frequency reader and an area sensing module, enables e-cigarettes to accurately identify the boundaries of no-smoking areas, achieving automated control over e-cigarette usage area restrictions. This avoids the lag of manual intervention, reduces the regulatory burden on public place managers, and stops illegal smoking behavior from a hardware perspective, thereby improving management efficiency and significantly enhancing the enforcement of public place smoking ban regulations.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0024] like Figure 1As shown, an embodiment of the area-restricted electronic cigarette operating circuit 10 of this disclosure includes a monitoring chip U1, an area sensing module 100, and an atomization switch module 200. The area sensing module 100 is used to receive electromagnetic activation signals emitted by a reader through a wireless radio frequency tag installed therein, and output sensing signals to the monitoring chip U1. The atomization switch module 200 is used to receive control signals from the monitoring chip U1, and control the on / off state of the heating element power supply circuit according to the control signals. The sensing signal feedback terminal RA1 of the monitoring chip U1 is connected to the sensing signal output terminal RW of the area sensing module 100, and the control terminal of the atomization switch module 200 is connected to the atomization signal control terminal Switch of the monitoring chip U1.

[0025] In this embodiment, when an e-cigarette is brought into a no-smoking area by a user and is within the effective identification range of a wireless RFID reader used for smoke control, the wireless RFID reader in that area sends an electromagnetic activation signal. The built-in wireless RFID tag then responds to the reader's RFID signal and outputs a corresponding sensing signal to the sensing signal feedback terminal RA1 of the monitoring chip U1. After receiving the sensing signal output by the area sensing module 100, the monitoring chip U1 analyzes the signal and determines that the e-cigarette is currently in a restricted smoking area. At this time, the atomization signal control terminal Switch of the monitoring chip U1 sends a shutdown control signal to the control terminal of the atomization switch module 200. Upon receiving this control signal, the atomization switch module 200 cuts off the power supply circuit to the heating element, thereby preventing current from flowing to the heating element for atomization by controlling the shutdown of the electronic switch tube inside the e-cigarette, thus achieving the function of mandatory smoke prohibition.

[0026] Furthermore, when the e-cigarette leaves the signal coverage area of ​​the RFID reader, the Switch terminal of the monitoring chip U1 sends a control signal allowing operation to the atomization switch module 200. Upon receiving this signal, the atomization switch module 200 drives the heating element to operate normally, enabling the e-cigarette to function properly. Specifically, during the above operation, the area sensing module 100 receives the RFID tag's response signal within the reader's signal coverage area and feeds it back to the monitoring chip U1. Based on the signal feedback from the area sensing module 100, the monitoring chip U1 dynamically controls the operating state of the atomization switch module 200, thereby restricting the e-cigarette's function in specific no-smoking areas.

[0027] The aforementioned area-restricting electronic cigarette operating circuit 10, through the technical means of real-time interaction between the wireless radio frequency reader and the area sensing module, enables the electronic cigarette to accurately identify the boundary of the no-smoking area, realize the automated control of the restriction of electronic cigarette use area, avoid the lag of manual intervention, reduce the supervision pressure of public place managers, and stop illegal smoking behavior from the hardware level, thereby improving management efficiency and significantly enhancing the enforcement of public place smoking ban regulations.

[0028] like Figure 1 As shown, in one embodiment, the area sensing module 100 includes a radio frequency (RF) sensing chip U2 and a first current-limiting resistor R3. The first end of the first current-limiting resistor R3 is connected to the battery power supply terminal, and the second end is connected to the power supply input terminal of the RF sensing chip. In this embodiment, during the operation of the RF sensing chip U2, the first current-limiting resistor R3 limits the current to the power supply input terminal of the RF sensing chip U2, preventing excessive current from damaging the RF sensing chip U2 and ensuring that the RF sensing chip U2 operates in a stable power environment. The RF sensing chip U2 has a built-in antenna for receiving electromagnetic activation signals emitted by a wireless RF reader. When an electronic cigarette is carried into a no-smoking area and is within the effective identification range of the reader, the reader emits an electromagnetic activation signal, which is captured by the antenna of the RF sensing chip U2. The RF sensing chip U2 uses a specific demodulation algorithm (such as ASK demodulation) to demodulate the information modulated on the carrier wave to obtain the baseband signal. Then, the decoding module inside the RF sensing chip U2 decodes the baseband signal according to a pre-set communication protocol. The decoded information is transmitted in the form of a digital signal through the output port of the radio frequency sensing chip U2 to the sensing signal feedback terminal RA1 of the monitoring chip U1. Then, the monitoring chip U1 outputs a corresponding control signal to the control terminal of the atomization switch module 200 according to the digital signal, thereby controlling the on / off of the power supply circuit of the heating element, and thus realizing the control of the working state of the electronic cigarette.

[0029] like Figure 1 As shown, in one embodiment, the area sensing module 100 further includes a first filter capacitor C1. The first end of the first filter capacitor C1 is connected to the power supply input terminal of the RF sensing chip, and the second end of the first filter capacitor C1 is grounded. In this embodiment, during the process of the battery supplying power to the RF sensing chip U2, the first filter capacitor C1 also begins to charge simultaneously. At this time, since the voltage across the first filter capacitor C1 cannot change abruptly, when the current suddenly increases, it can absorb the instantaneous current surge in the circuit, preventing excessive current and voltage from damaging the RF sensing chip U2. Specifically, when the power supply voltage rises slightly, the first filter capacitor C1 absorbs excess charge for charging; and when the power supply voltage drops slightly, the first filter capacitor C1 releases the previously stored charge, providing additional current to the circuit, thereby maintaining the relative stability of the power supply input voltage of the RF sensing chip. Furthermore, for high-frequency noise signals present in the power supply, the first filter capacitor C1 acts as a low-impedance path, allowing the high-frequency noise signal to flow into the ground terminal through the first filter capacitor C1, thereby ensuring that the RF sensing chip U2 obtains a stable operating current.

[0030] like Figure 1As shown, in one embodiment, the radio frequency sensing chip U2 is an RFID sensing chip. In this embodiment, the RFID sensing chip has a built-in miniature antenna. When the e-cigarette is carried into a no-smoking area and is within the effective identification range of the RFID reader, the electromagnetic activation signal emitted by the reader is captured by the chip's antenna. After receiving the signal, the RFID sensing chip processes it through its internal demodulation and decoding module. The processed information is transmitted in the form of a digital signal through the sensing signal output terminal RW of the RFID sensing chip to the sensing signal feedback terminal RA1 of the monitoring chip U1, thereby enabling the monitoring chip U1 to determine whether the e-cigarette is in a no-smoking area.

[0031] like Figure 1 As shown, in one embodiment, the atomization switch module 200 includes an atomization control switch Q1 and a second current-limiting resistor R1. The first end of the atomization control switch Q1 is connected to the battery power supply terminal, and the second end is connected to the heating element. The control terminal of the atomization control switch Q1 is connected to the atomization signal control terminal Switch of the monitoring chip U1 via the second current-limiting resistor R1. In this embodiment, when the electronic cigarette is in a permitted smoking area, i.e., outside the effective identification range of the wireless radio frequency reader, the atomization signal control terminal Switch of the monitoring chip U1 sends a control signal allowing operation to the control terminal of the atomization control switch Q1, thereby turning on the atomization control switch Q1 and forming a complete power supply circuit between the battery power supply terminal and the heating element. The battery current flows to the heating element through the turned-on atomization control switch Q1. Meanwhile, the second current-limiting resistor R1 limits the current flowing to the control terminal of the atomization control switch Q1, ensuring that the current flowing to the control terminal of the atomization control switch Q1 is within a safe and appropriate range, and avoiding damage to the atomization control switch Q1 due to excessive current.

[0032] Furthermore, when an e-cigarette is brought into a no-smoking area and is within the effective identification range of the RFID reader, the RFID sensing chip in the area sensing module 100 receives and processes the electromagnetic activation signal emitted by the reader, and then transmits the sensing signal containing area information to the monitoring chip U1. After analyzing the signal, the monitoring chip U1 determines that the e-cigarette is in a restricted smoking area. At this time, the atomization signal control terminal Switch of the monitoring chip U1 sends a shutdown control signal to the control terminal of the atomization control switch Q1, causing the atomization control switch Q1 to turn off and cut off the power supply circuit between the battery power supply terminal and the heating element. This prevents current from flowing to the heating element, the heating element stops heating, and thus atomization cannot be performed, achieving the function of mandatory smoking ban.

[0033] like Figure 1As shown, in one embodiment, the atomization switch module 200 further includes a first voltage divider resistor R2. The first end of the first voltage divider resistor R2 is connected to the battery power supply terminal, and the second end of the first voltage divider resistor R2 is connected to the first end of the atomization control switch Q1. In this embodiment, when the electronic cigarette is in a permitted smoking area, the atomization signal control terminal Switch of the monitoring chip U1 sends a control signal to the control terminal of the atomization control switch Q1, enabling the atomization control switch Q1 to conduct. At this time, the voltage from the battery power supply terminal reaches the heating element through the first voltage divider resistor R2 and the conducting atomization control switch Q1. The first voltage divider resistor R2 divides the voltage from the battery power supply terminal, preventing excessively high voltage from being directly applied to the heating element, thus preventing damage to the heating element due to excessive voltage and ensuring it operates at a suitable voltage. When the electronic cigarette enters a prohibited smoking area, the monitoring chip U1 sends a shutdown control signal to turn off the atomization control switch Q1.

[0034] like Figure 1 As shown, in one embodiment, the atomization control switch Q1 is an NPN transistor. In this embodiment, the first terminal of the atomization control switch Q1 is the collector of the NPN transistor, the second terminal of the atomization control switch Q1 is the emitter of the NPN transistor, and the control terminal of the atomization control switch Q1 is the base of the NPN transistor. When the e-cigarette is in a permitted smoking area, the atomization signal control terminal Switch of the monitoring chip U1 outputs a high-level signal to the base of the atomization control switch Q1. Due to the characteristics of the NPN transistor, when sufficient current flows into the base, the collector and emitter of the transistor will conduct. At this time, the current from the battery power supply flows from the collector, passes through the emitter, and flows to the heating element, thereby providing operating current for the heating element, causing the heating element to heat up and atomize the e-liquid in the e-cigarette. Furthermore, when the e-cigarette enters a no-smoking area, the Switch terminal of the monitoring chip U1 outputs a low-level signal to the base of the atomization control switch Q1. According to the working principle of the NPN transistor, when the base current cannot reach the conduction threshold, the collector and emitter are cut off, thereby cutting off the current loop between the battery power supply terminal and the heating element to limit the atomization of the e-liquid.

[0035] like Figure 1As shown, in one embodiment, the area-restricted electronic cigarette operating circuit 10 further includes an LED warning module. The LED warning module includes a second voltage divider resistor R4 and an LED light. The first end of the second voltage divider resistor R4 is connected to the battery power supply terminal, the second end of the second voltage divider resistor R4 is connected to the positive terminal of the LED light, and the negative terminal of the LED light is connected to the indicator light signal terminal of the monitoring chip U1. In this embodiment, when the electronic cigarette is outside the signal coverage range of the wireless radio frequency reader, the monitoring chip U1 does not receive the prohibition signal from the area sensing module 100, and its indicator light signal terminal outputs a high-level signal. At this time, the negative terminal of the LED light receives a high level, causing the LED light to be reverse-biased and cut off, i.e., the LED light is in an off state. In this state, the second voltage divider resistor R4 forms a voltage divider circuit with the internal resistance of the LED light, ensuring that the battery voltage is not directly applied to the two ends of the LED, avoiding damage to the LED due to excessive forward overvoltage. When the e-cigarette enters the effective identification range of the RFID reader, the RFID sensing chip of the area sensing module 100 transmits the no-smoking zone signal to the monitoring chip U1. After parsing, the monitoring chip U1 confirms that it is in a restricted area, and its indicator light signal terminal switches to a low-level output. The low-level signal lowers the negative potential of the LED. When the voltage difference between the positive and negative terminals reaches the LED's conduction voltage, the LED conducts in the forward direction and lights up. The second voltage divider resistor R4 acts as a current limiter in this process, limiting the current to the LED's rated operating current range to prevent overcurrent from burning out the LED. The visual status warning LED provides real-time feedback to the user on the restricted area status of the e-cigarette by its on / off state, eliminating the need for the user to actively check the device status, thus improving ease of use.

[0036] like Figure 1As shown, in one embodiment, the monitoring chip U1 is model SC8F5775. In this embodiment, when it is determined that the electronic cigarette is in a no-smoking area, the atomization signal control terminal Switch of the SC8F5775 monitoring chip U1 outputs a low-level shutdown control signal to the base of the NPN transistor in the atomization switch module 200. Due to the characteristics of the NPN transistor, the low-level signal will cut off the collector and emitter of the transistor, thereby cutting off the power supply circuit between the battery power supply terminal and the heating element, preventing current from flowing to the heating element, and realizing the function of forcibly prohibiting smoking. When the electronic cigarette leaves the no-smoking area, and the SC8F5775 monitoring chip U1 determines that it is in a permitted smoking area, the atomization signal control terminal Switch outputs a high-level permitted operation control signal, turning on the transistor and restoring the power supply to the heating element. On the other hand, the indicator light signal terminal of the SC8F5775 monitoring chip U1 will also output a corresponding level signal to control the LED warning module according to the judgment result. When in a permitted smoking area, the indicator light outputs a high-level signal, turning off the LED. When entering a prohibited smoking area, the indicator light outputs a low-level signal, turning on the LED and providing a visual status warning. Specifically, the high-performance signal processing capabilities of the SC8F5775 monitoring chip U1 ensure that the e-cigarette can accurately identify the boundaries of prohibited smoking areas. Its fast signal analysis and comparison speed allows the e-cigarette to respond quickly when entering or leaving a prohibited smoking area, achieving automated control of e-cigarette usage area restrictions. Compared with traditional mechanical or manual intervention methods, this significantly improves the accuracy and response speed of area identification, avoiding violations caused by the lag in manual intervention.

[0037] This application also provides an electronic atomizer, including a zone-restricted electronic cigarette operating circuit 10 according to any embodiment. In this embodiment, when an electronic cigarette is carried by a user into a no-smoking area and is within the effective identification range of a wireless radio frequency reader for smoke-free purposes, the wireless radio frequency reader in that area sends an electromagnetic activation signal. The built-in wireless radio frequency tag then responds to the reader's radio frequency signal and outputs a corresponding sensing signal to the sensing signal feedback terminal RA1 of the monitoring chip U1. After receiving the sensing signal output by the zone sensing module 100, the monitoring chip U1 analyzes the signal and determines that the electronic cigarette is currently in a restricted smoking area. At this time, the atomization signal control terminal Switch of the monitoring chip U1 sends a shutdown control signal to the control terminal of the atomization switch module 200. After receiving this control signal, the atomization switch module 200 cuts off the power supply circuit to the heating element, thereby preventing current from flowing to the heating element for atomization by controlling the shutdown of the electronic switch tube inside the electronic cigarette, thus achieving the function of mandatory smoke-free prohibition. Furthermore, when the e-cigarette leaves the signal coverage area of ​​the RFID reader, the Switch terminal of the monitoring chip U1 sends a control signal allowing operation to the atomization switch module 200. Upon receiving this signal, the atomization switch module 200 drives the heating element to operate normally, enabling the e-cigarette to function properly. Specifically, during the above operation, the area sensing module 100 receives the RFID tag's response signal within the reader's signal coverage area and feeds it back to the monitoring chip U1. Based on the signal feedback from the area sensing module 100, the monitoring chip U1 dynamically controls the operating state of the atomization switch module 200, thereby restricting the e-cigarette's function in specific no-smoking areas.

[0038] Compared with the prior art, this disclosure has at least the following advantages:

[0039] The aforementioned area-restricting electronic cigarette operating circuit 10, through the technical means of real-time interaction between the wireless radio frequency reader and the area sensing module, enables the electronic cigarette to accurately identify the boundary of the no-smoking area, realize the automated control of the restriction of electronic cigarette use area, avoid the lag of manual intervention, reduce the supervision pressure of public place managers, and stop illegal smoking behavior from the hardware level, thereby improving management efficiency and significantly enhancing the enforcement of public place smoking ban regulations.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
