AI Technical Summary
Electronic cigarettes may experience issues such as dry burning, scorching, or breakage of the atomizing chamber during transportation, especially if the device starts automatically when it is not filled with e-liquid, or if the atomizing chamber is filled with e-liquid but the e-liquid bottle is not connected, which can damage the product.
A control module and switch circuit are installed inside the e-cigarette device. A Hall chip is used to sense the magnetic force of the magnet to control the working state of the atomizer. The control module only allows the atomizer to work normally when the device and the bottle are correctly connected; otherwise, it remains in the off state.
This effectively avoids the problems of dry burning or self-starting when the e-cigarette rod is not connected to the oil bottle, ensuring product safety and reliability and extending the product's service life.

Abstract
Description

[0001] This utility model relates to an electronic cigarette circuit and an electronic cigarette with an anti-smoking rod that can be turned on by itself, and belongs to the field of electronic cigarette technology. Background Technology
[0002] E-cigarettes are electronic products that mimic traditional cigarettes. Some e-cigarettes are shipped with the device and e-liquid bottle separate, requiring the user to assemble them for proper function. However, during transportation, e-cigarettes are subject to bumps and vibrations. For e-cigarettes with an empty atomizer chamber, starting them before assembling the e-liquid bottle may result in dry burning, scorching, or breakage. For e-cigarettes with an e-liquid chamber, self-starting may occur during transportation or storage, leading to e-liquid depletion or even dry burning. Utility Model Content

[0036] Figure 3 This is a schematic diagram of the self-starting electronic cigarette module of the smoke-proof rod according to an embodiment of the present invention. Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0038] Example:
[0039] Firstly, reference Figure 1This utility model embodiment provides an electronic cigarette circuit that prevents the cigarette holder from automatically starting, which is installed inside the cigarette holder of the electronic cigarette. The electronic cigarette includes the cigarette holder and the cigarette bottle, and the cigarette bottle is provided with a magnet.
[0040] Includes: a control module 10, a switching circuit 20, and an atomizer 30 connected in sequence;
[0041] The control module 10 controls whether the switching circuit 20 is working properly based on whether the magnetic force of the magnet is sensed, thereby controlling whether the atomizer 30 is working properly.
[0042] In this embodiment of the invention, when the control module 10 senses the magnetic force of the magnet, the switching circuit 20 can work normally, thereby controlling the atomizer 30 to work normally. The switching circuit can be turned on or off according to the inhalation action, thereby controlling the atomizer to turn on or off. Conversely, if the control module 10 does not sense the magnetic force of the magnet, the switching circuit will not work normally and will always remain in the off state, thereby keeping the atomizer in the off state. Even if inhalation or self-starting is performed, the atomizer cannot be turned on, thereby avoiding the self-starting of the electronic cigarette.
[0043] Through the above-described settings, this embodiment of the utility model can achieve the following:
[0044] 1) For e-cigarettes shipped without filling the atomizing chamber with e-liquid, this avoids the problem of the heating element burning dry, scorching, or breaking when consumers start vaping without connecting the e-liquid bottle. Normal vaping can only be performed after connecting the e-liquid bottle.
[0045] 2) For e-cigarette atomizing chamber filling and shipping products, the risk of self-starting during transportation or warehouse storage can be eliminated when the oil bottles are not spliced.
[0046] In addition, according to design requirements, the e-cigarette can be used to draw in directly after the oil bottle is installed, or it can be used to draw in normally after a certain period of time (the time is adjustable). During the delay, the user can be prompted by LED lights or displays on the e-cigarette or by vibration from the motor to pour the oil from the oil bottle into the atomizing chamber on the e-cigarette. This provides a clearer and more specific reminder.
[0047] As a preferred embodiment of this utility model, refer to Figure 1-2 The control module includes a Hall chip U1 and an MCU chip U2 connected in sequence;
[0048] When the Hall chip U1 senses the magnetic force of the magnet, it determines that the oil bottle has been assembled, and then sends a first signal to the MCU chip U2, so that the MCU chip U2 is connected to the output interface of the switching circuit normally.
[0049] When the Hall chip U1 does not sense the magnetic force of the magnet, it determines that the oil bottle is not connected, and sends a second signal to the MCU chip U2, so that the MCU chip U2 is locked to the output interface of the switch circuit.
[0050] It uses a built-in Hall element, which can be separated from the magnet by a plastic shell or other materials that do not affect the magnetic force, so as not to affect the product appearance and avoid accidental touch.
[0051] As a preferred embodiment of this utility model, refer to Figure 2 The first pin of the Hall chip U1 is connected to the positive power input terminal BAT+;
[0052] The second pin of the Hall chip U1 is grounded;
[0053] The third pin of the Hall chip U1 is connected to the third pin of the MCU chip U2.
[0054] In a preferred embodiment of this utility model, the third pin of the Hall chip U1 is also connected to a resistor R1.
[0055] Among them, resistor R1 can play an isolation role, avoiding the damage to the MCU chip caused by high voltage and high current when there is a problem with the placement of the Hall chip, and at the same time reducing the static current loss of the circuit.
[0056] In a preferred embodiment of this utility model, the fifth pin of the MCU chip U2 is connected to the switching circuit;
[0057] After receiving the first signal, the fifth pin of the MCU chip U2 normally switches between high and low potentials.
[0058] After receiving the second signal, the MCU chip U2 locks its fifth pin, keeping the fifth pin of the MCU chip U2 at a high potential output at all times.
[0059] Preferably, the second signal is a high level, that is, when the Hall chip U1 does not sense the magnetic force of the magnet, the third pin of the Hall chip U1 outputs a high level, and when the MCU chip U2 detects that the Hall chip U1 outputs a high level, it locks the fifth pin of the MCU chip U2 so that the fifth pin always maintains a high potential output.
[0060] The first signal is preferably low level. That is, when the Hall chip U1 senses the magnetic force of the magnet, the output of the third pin of the Hall chip U1 changes from high level to low level. When the MCU chip U2 detects that the output of the Hall chip U1 is low level, it unlocks the fifth pin of the MCU chip U2 (or performs delayed unlocking). At this time, the fifth pin can work normally. For example, when inhaling, it can output a low level to control the switch circuit to open, thereby powering the atomizer and performing normal inhalation.
[0061] In a preferred embodiment of this utility model, the switching circuit includes: a voltage divider circuit and a MOSFET Q1.
[0062] In a preferred embodiment of the present invention, the voltage divider circuit includes resistors R3, R2, and R5.
[0063] The fifth pin of the MCU chip, resistors R3, R2, and R5, and one end of the atomizer L1 are connected in series.
[0064] The resistor R3 has a resistance of 100 ohms; the resistor R2 has a resistance of 10K ohms; and the resistor R5 has a resistance of 1M ohms.
[0065] In a preferred embodiment of this utility model, the MOS transistor Q1 is a PMOS transistor;
[0066] The drain of the MOS transistor Q1 is connected between the resistor R5 and one end of the atomizer L1.
[0067] The source (S) terminal of the MOSFET Q1 is connected between resistors R2 and R5, and to the positive power input terminal.
[0068] The gate (G) of the MOSFET Q1 is connected between resistors R3 and R2.
[0069] In a preferred embodiment of this utility model, the other end of the atomizer L1 is grounded.
[0070] Preferably, when the fifth pin of the MCU chip U2 is always kept at a high potential output, the MOS transistor Q1 is turned off, thereby preventing the atomizer L1 from being powered and thus unable to work properly.
[0071] When the MCU chip U2 detects that the Hall chip U1 outputs a low level, the fifth pin of the MCU chip U2 is unlocked (or a delayed unlock is performed). At this time, the fifth pin can work normally. For example, when inhaling, it can output a low level to control the MOS transistor Q1 to conduct, thereby supplying power to the atomizer L1 normally, and normal inhalation can be performed.
[0072] Secondly, this utility model also provides an electronic cigarette with an anti-smoking mechanism that automatically starts, including a cigarette rod 1 and a cigarette bottle 2;
[0073] The cigarette bottle 2 is equipped with a magnet 3;
[0074] The cigarette rod 1 is equipped with an electronic cigarette circuit 4 that prevents the cigarette rod from starting automatically, as in any embodiment of this utility model.
[0075] When the cigarette bottle 2 is correctly assembled into the cigarette rod 1, the Hall chip 5 of the electronic cigarette circuit 4 that prevents the cigarette rod from starting automatically is positioned close to the magnet 3.
[0076] The above description is only a preferred embodiment of this utility model patent, but the protection scope of this utility model patent is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in this utility model patent, based on the technical solution and utility model concept of this utility model patent, shall fall within the protection scope of this utility model patent.
