Description

Technical Field

[0001] This utility model relates to the field of electronic atomizers, specifically to an anti-self-starting device for electronic atomizers. Background Technology

[0002] Electronic atomizers rely on internal airflow sensors to detect whether the user is smoking or not. If smoking is detected, the power transistor is controlled to drive the heating coil, generating heat to atomize the e-liquid. Currently, the mainstream airflow sensors are capacitive sensors. When there is a smoking action, the sensor capacitance changes. When the backend MCU / ASIC detects that the capacitance change reaches a threshold, it determines that the user is smoking.

[0003] In practical applications, factors such as evaporation of e-liquid inside the product, oil leakage, and condensation of mist after inhalation can all cause changes in capacitance, which may be mistaken for smoking and trigger self-starting. Self-starting can pose safety hazards and is a pain point for the entire industry. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide an anti-self-starting device for electronic atomizers that can achieve dual detection to prevent self-starting.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] An anti-self-starting device for an electronic atomizer, characterized in that: it includes a housing, an oil-guiding cotton is sleeved inside the housing, an atomizing component is connected inside the oil-guiding cotton, a contact control component is fixedly connected to the output end of the atomizing component, an airflow control component is connected between the oil-guiding cotton and the housing, a first air chamber is formed between the airflow control component and the housing, a second air chamber is formed between the airflow control component and the oil-guiding cotton, a top cover is fixedly connected to the top of the housing, and the contact control component is disposed through the top cover.

[0007] As an improvement: the atomizing component includes an atomizing core tube, a main control chip is fixedly connected to the bottom of the atomizing core tube, a power tube is fixedly connected inside the atomizing core tube, the power tube is electrically connected to the main control chip, and an atomizing output port is opened at the output end of the atomizing core tube.

[0008] As an improvement: the airflow control component includes a first limiting mounting plate and a second limiting mounting plate, the first limiting mounting plate being disposed near the first air chamber, the second limiting mounting plate being disposed near the second air chamber, the first limiting mounting plate being fixedly connected to the inside of the outer casing, and the second limiting mounting plate being fixedly connected to the inside of the outer casing.

[0009] As an improvement: both the first and second limiting mounting plates are provided with main air passages, which are set to correspond to the atomizing components. An airflow sensor is clamped and connected between the first and second limiting mounting plates. Both the first and second limiting mounting plates are provided with auxiliary air intake passages, which are set to correspond to the airflow sensor. The airflow sensor is set to correspond to the main control chip.

[0010] As an improvement, an air inlet is provided at the bottom of the outer casing, and the air inlet is configured to correspond to the main air passage.

[0011] As an improvement: the contact control component includes an air intake guide tube, on which a contact capacitance sensor is fixedly connected. The contact capacitance sensor is electrically connected to the main control chip. A positioning mounting ring is sleeved on the air intake guide tube and is fixedly connected to the top cover plate.

[0012] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0013] The airflow control component, through an airflow sensor, detects the airflow passing through the auxiliary air intake, thereby determining whether a person is smoking. Airflow changes the capacitance of the airflow sensor. A contact capacitance sensor, through a contact control component, detects when the lips touch the mouthpiece during smoking, causing a change in the capacitance value of the contact capacitance sensor, thus identifying a contact action. These capacitance changes from the airflow sensor and the contact capacitance sensor are converted into electrical signals and transmitted to the main control chip. This allows the main control chip to control the power transistor's atomization of the e-liquid. This ensures that when the airflow sensor outputs a signal due to e-liquid evaporation, leakage, or condensation after inhalation, the contact capacitance sensor does not output a signal, preventing the main control chip from identifying a smoking action. This effectively avoids the risk of self-starting, addresses industry pain points, and improves product safety and reliability. Attached Figure Description

[0018] Example: As attached Figures 1 to 3 The device shown is an anti-self-starting device for an electronic atomizer, comprising a housing 1, an oil-guiding cotton 7 sleeved inside the housing 1, an atomizing component 8 connected inside the oil-guiding cotton 7, a contact control component 4 fixedly connected to the output end of the atomizing component 8, an airflow control component 3 connected between the oil-guiding cotton 7 and the housing 1, forming a first air chamber 5 between the airflow control component 3 and the housing 1, and a second air chamber 6 between the airflow control component 3 and the oil-guiding cotton 7, and a top cover plate 9 fixedly connected to the top of the housing 1, with the contact control component 4 penetrating through the top cover plate 9.

[0019] The atomizing component 8 includes an atomizing core tube 81, with a main control chip 82 fixedly connected to the bottom of the atomizing core tube 81. A power tube 83 is fixedly connected inside the atomizing core tube 81 and electrically connected to the main control chip 82. The atomizing core tube 81 has an atomization output port 84 at its output end. The power tube 83 atomizes the oil from the wicking cotton 7 into vapor. The main control chip 82 effectively controls the opening and closing of the power tube 83 based on the smoking action, avoiding the risk of self-starting. The atomizing core tube 81 prevents damage to the power tube 83.

[0020] The airflow control component 3 includes a first limiting mounting plate 31 and a second limiting mounting plate 32. The first limiting mounting plate 31 is disposed near the first air chamber 5, and the second limiting mounting plate 32 is disposed near the second air chamber 6. The first limiting mounting plate 31 and the second limiting mounting plate 32 are fixedly connected to the interior of the outer casing 1. The first air chamber 5 and the second air chamber 6 effectively facilitate the entry of gas, while the first limiting mounting plate 31 and the second limiting mounting plate 32 serve to limit the position of the gas.

[0021] Both the first limiting mounting plate 31 and the second limiting mounting plate 32 have main air passages 34, which are configured to correspond to the atomizing component 8. An airflow sensor 33 is clamped and connected between the first limiting mounting plate 31 and the second limiting mounting plate 32. Both the first limiting mounting plate 31 and the second limiting mounting plate 32 have auxiliary air intakes 35, which are configured to correspond to the airflow sensor 33. The airflow sensor 33 can change its capacitance according to the flow of air, thereby controlling the main control chip 82 and determining whether a smoking action is being performed.

[0022] The bottom of the outer casing 1 is provided with an air inlet 2, which is correspondingly arranged with the main air passage 34. The air inlet 2 ensures the normal introduction of gas, and the gas can effectively enter the main air passage 34 and the auxiliary air inlet 35 through the first air chamber 5, and then enter the second air chamber 6.

[0023] The contact control component 4 includes an air intake guide tube 41, on which a contact capacitance sensor 43 is fixedly connected. The contact capacitance sensor 43 is electrically connected to the main control chip 82. A positioning mounting ring 42 is fitted onto the air intake guide tube 41 and is fixedly connected to the top cover plate 9. The air intake guide tube 41 allows for the inhalation of atomized smoke. The contact capacitance sensor 43 detects whether the user's mouth is in contact with the air intake guide tube 41, thus determining whether the user is in a smoking state. The capacitance change is converted into an electrical signal and transmitted to the main control chip 82 to control the power transistor 83 to turn on and off.

[0024] This ensures that when the airflow sensor 33 sends a signal due to reasons such as e-liquid evaporation, oil leakage, or condensation of mist after inhalation, the contact capacitance sensor 43 does not output a signal. This prevents the main control chip 82 from judging it as a smoking action, effectively avoiding the risk of self-starting, solving industry pain points, and improving product safety and reliability.
