Description

Technical Field

[0001] This utility model belongs to the technical field of aerosol conveying devices, and specifically relates to an aerosol conveying device. Background Technology

[0002] Current aerosol delivery devices employ a single heating element structure, which inherently suffers from drawbacks including thermal hysteresis (slow heating of the heating element, typically requiring 3-5 seconds), resulting in users inhaling unheated airflow in the first few breaths; low heat transfer efficiency (relying on natural convection and unable to force-deliver heated airflow); and uneven temperature distribution (single-point heating easily leads to localized overheating while the surrounding temperature remains insufficient). Therefore, to avoid these shortcomings, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to provide an aerosol delivery device that can reduce heating lag, improve heat conduction efficiency, and deliver heated warm airflow to the mouthpiece, ensuring that the user's first inhalation is a warm airflow, thus enhancing the user experience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An aerosol delivery device includes a housing, a heating device, a blower, a controller, and a power supply. One end of the housing has an end cap with a suction nozzle. The lower end of the end cap is a formulation chamber formed by a hollow cylindrical structure, which communicates with the suction nozzle. A perforated cover plate is provided at the bottom of the formulation chamber. The heating device is located at the bottom of the formulation chamber and is separated from it by the perforated cover plate. The heating device includes at least two heating elements. The blower is located inside the housing and below the heating device, with its outlet aligned with the suction nozzle. The controller is located inside the housing and is electrically connected to both the heating device and the blower. The power supply is located inside the housing and below the blower, supplying power to the heating device, the blower, and the controller.

[0006] As a preferred embodiment of the above-mentioned aerosol delivery device, the heating element is disposed at the bottom of the formulation chamber, and the heating element is evenly distributed along the bottom circumference of the formulation chamber.

[0007] As a preferred embodiment of the above-mentioned aerosol delivery device, a mounting base is provided below the formulation chamber, and the heating device and the air supply fan are sequentially arranged in the mounting base. Ventilation holes are provided at the bottom of the mounting base and the bottom of the casing.

[0024] Please refer to the following: Figures 1 to 3 The aerosol conveying device provided in the embodiments of this utility model will now be described.

[0025] like Figures 1 to 3As shown, the aerosol conveying device of this utility model includes a housing 100, a heating device 300, a blower 400, a controller 600, and a power supply device 500. One end of the housing 100 is provided with an end cap, on which a suction nozzle 110 is provided. The lower end of the end cap is a formula chamber 200 formed by a hollow cylindrical structure, which communicates with the suction nozzle 110. A perforated cover plate 220 is provided at the bottom of the formula chamber 200. The heating device 300 is located at the bottom of the formula chamber 200 and is separated from the formula chamber 200 by the perforated cover plate 220. The heating device 300 includes... At least two heating elements 310 are provided. The air supply fan 400 is disposed inside the housing 100 and located below the heating element 300. The air outlet of the air supply fan 400 is aligned with the suction nozzle 110. The controller 600 is disposed inside the housing 100 and is electrically connected to the heating element 300 and the air supply fan 400. The power supply device 500 is disposed inside the housing 100 and located below the air supply fan 400. The power supply device 500 supplies power to the heating element 300, the air supply fan 400, and the controller 600.

[0026] Specifically, this technical solution uses a power supply device 500 to supply power, which is then transmitted to a controller 600. The controller 600 then issues a command to release the current to the heating element 310 of the heating device 300. The heating element 310 provides heat to heat the airflow. The airflow is heated by the heating element 310, transforming into hot air that rises and passes through the formulation chamber 200, carrying out the components and aromas from the tobacco formulation and delivering them to the body for absorption. The tobacco formulation in the formulation chamber 200 can be in a solid, semi-solid, or liquid state, and its components can be nicotine, flavorings, pharmaceuticals, or health products. Simultaneously, the output current and the issued commands also reach the blower 400. The blower 400's fan rotates, delivering the hot airflow to the mouthpiece 110. This better heats the formulation, allowing the user to inhale a warm airflow with their first breath, enhancing the user experience.

[0027] For example, the heating element 310 is disposed at the bottom of the formulation chamber 200, and the heating element 310 is evenly distributed circumferentially along the bottom of the formulation chamber 200. The placement of the heating element 310 at the bottom of the formulation chamber 200 enables efficient heating of the airflow within the formulation chamber 200, and the even distribution of the heating element 310 along the bottom of the formulation chamber 200 ensures uniform heating, guaranteeing that all parts of the airflow within the formulation chamber 200 are heated.

[0028] For example, a mounting base 410 is provided below the formula compartment 200. The heating device 300 and the air supply fan 400 are sequentially arranged inside the mounting base 410. Ventilation holes 800 are provided at the bottom of the mounting base 410 and the bottom of the housing 100. An air passage is formed through the ventilation holes 800, the through holes 210 on the perforated cover plate 220, and the air outlet holes 111 on the suction nozzle 110, enabling the air supply fan 400 to draw and blow air, and ensuring that the heated airflow is accurately delivered to the direction of the suction nozzle 110. The mounting base 410 separates the heating device 300 and the air supply fan 400 from the power supply device 500, facilitating installation.

[0029] For example, the perforated cover plate 220 is provided with a plurality of through holes 210. By providing multiple through holes 210, it is convenient for the heated airflow to be transported upward through the formula chamber 200, so that the concentration of gas containing tobacco formula components after volatilization is more uniform, thereby improving the smoking experience.

[0030] For example, the mouthpiece 110 includes a plurality of evenly arranged air outlets 111. The multiple evenly arranged air outlets 111 allow the airflow to be distributed evenly, preventing the user from choking while inhaling.

[0031] For example, the power supply device 500 is a rechargeable lithium battery. Lithium batteries have high energy density, are easy to charge, and can stably provide power to the heating device 300, the blower 400, and the controller 600.

[0032] For example, a start button 700 is provided on the housing 100, and the start button 700 is electrically connected to the controller 600. The start button 700 is provided for controlling the start and stop of the aerosol delivery device.

[0033] The aerosol delivery device provided by this utility model has the following advantages compared with the prior art:

[0034] The formulation chamber 200 of this invention can hold formulations such as tobacco, flavorings, fragrances, and medicines. A heating device 300 located at the bottom of the formulation chamber 200 heats the airflow within it, causing the hot airflow to rise and carry the components and aromas of the tobacco formulation out through the chamber. The formulation chamber 200 is connected to the mouthpiece 110, allowing the heated air to flow to the mouthpiece for the user to inhale. The heating device 300 includes at least two heating elements 310. This multi-element structure not only increases heating efficiency but also ensures more even heating. A blower 400 is located in the middle of the heating device 300, delivering the heated airflow to the mouthpiece 110, ensuring that the user's first inhale is warm, heated air. The airflow reduces heating lag, improves heat transfer efficiency, and enhances the user experience. The blower 400 delivers the airflow heated by the heating element 310 to the mouthpiece 110, thus eliminating reliance on natural airflow and continuously delivering warm airflow from the heating element 310 to the mouthpiece 110, ensuring that every breath inhaled by the user remains warm. The power supply 500 provides power to both the heating element 300 and the blower 400, maintaining stable operation of the aerosol delivery device. The controller 600 is connected to the heating element 300, the blower 400, and the power supply 500, and can independently control the operation of each component. When the internal temperature of the aerosol delivery device is stable, it can control only one of the heating elements 310 of the heating element 300 to operate to maintain the internal temperature of the aerosol delivery device, thereby saving energy.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
