Abstract
Provided in the present invention are an atomizer and an aerosol generation device. In the structure of the atomizer, by disposing a sensing air cavity at the position inside an accommodating body close to an air outlet, a pneumatic trigger assembly is mounted in the sensing air cavity. When a user inhales an aerosol through the air outlet, under the action of a negative pressure formed by inhalation, air pressure difference is formed between two sides of the pneumatic trigger assembly, so that after sensing the air pressure difference, the pneumatic trigger assembly can trigger an atomization core to activate atomization work. Since the pneumatic trigger assembly is disposed at the position close to the air outlet, the length of an air passage connecting a second chamber and the air outlet is shortened, reducing inhalation resistance of the air passage, thereby significantly improving the sensitivity of the pneumatic trigger assembly being triggered by inhalation airflow. In addition, the pneumatic trigger assembly is arranged at the position close to the air outlet, preventing atomized liquid or condensate leaked from the bottom of the atomizer from corroding the pneumatic trigger assembly and causing malfunction or damage to the pneumatic trigger assembly, thereby prolonging the service life of the pneumatic trigger assembly.
Description
本发明属于雾化技术领域，特别地，涉及一种雾化器及气溶胶生成装置。The present invention belongs to the technical field of atomization, and in particular, relates to an atomizer and an aerosol generating device.

The atomizer can heat and atomize the atomized liquid stored in the atomizer to form an aerosol under the electric drive of the power supply device. At present, the aerosol generating device that starts working by sensing the airflow through a microphone switch generally sets the microphone switch at the bottom of the power supply device, and sets an airway on the power supply device. The airway connects the microphone switch and the air outlet on the atomizer. When the user inhales at the air outlet, a suction negative pressure is generated in the airway to trigger the microphone switch to start working. However, since the microphone switch is far away from the air outlet, there are defects such as a long airway and a large airway suction resistance, which not only easily reduces the sensitivity of the microphone switch to be triggered, but also causes the microphone switch to malfunction, affecting the normal start-up of the aerosol generating device.

本发明实施例中的雾化器及气溶胶生成装置，雾化器结构中，通过在雾化弹主体内部临近出气口的位置设有感应气腔，将气动触发组件安装于感应气腔中，并在气动触发组件的两侧分别形成第一腔室和第二腔室，第一腔室内的压强为标准大气压，第二腔室通过气道与出气口连通。用户通过出气口抽吸气溶胶时，在抽吸形成的负压作用下，第二腔室内形成负压，使得气动触发组件的两侧形成气压差，气动触发组件感应到气压差后便可触发雾化芯启动雾化工作。由于将气动触发组件设置在临近出气口的位置，缩短了连通第二腔室与出气口的气道的长度，减小了气道的吸阻，可显著提高气动触发组件被抽吸气流触发的灵敏度，有效防止气动触发组件失灵。此外，将气动触发组件设置在临近出气口的位置，可避免由雾化器底部泄漏的雾化液或冷凝液对气动触发组件产生侵蚀，造成气动触发组件失灵或损坏，从而可延长气动触发组件的使用寿命。The atomizer and aerosol generating device in the embodiment of the present invention, in the atomizer structure, a sensing air cavity is provided at a position near the air outlet inside the atomizer bomb body, a pneumatic trigger assembly is installed in the sensing air cavity, and a first chamber and a second chamber are formed on both sides of the pneumatic trigger assembly, respectively, the pressure in the first chamber is the standard atmospheric pressure, and the second chamber is connected to the air outlet through an airway.

An induction air cavity is provided inside the atomizer bomb body 1 near the air outlet 16. The pneumatic trigger assembly 3 is installed in the induction air cavity. The pneumatic trigger assembly 3 is used to trigger the atomizer core 2 to start the atomization work when negative pressure is sensed. A first chamber 18 is formed on one side of the pneumatic trigger assembly 3. The pressure in the first chamber 18 is the standard atmospheric pressure. A second chamber 33 is formed on the other side of the pneumatic trigger assembly 3. An airway 34 is provided on the pneumatic trigger assembly 3. The airway 34 connects the second chamber 33 with the air outlet 16. When the user inhales the aerosol through the air outlet 16, under the action of the negative pressure formed by the suction, the external air is introduced into the atomizer chamber 14 through the air inlet 17. At the same time, the second chamber 33 is connected to the air outlet 16 through the airway 34, and negative pressure is also formed in the second chamber 33. At this time, since the pressure in the first chamber 18 is the standard atmospheric pressure, a pressure difference can be formed on both sides of the pneumatic trigger component 3. After the pneumatic trigger component 3 senses the pressure difference, it starts working, thereby triggering the atomizer core 2 to start atomization. It should be noted that the pneumatic trigger component 3 can trigger the start of the work when the pressure difference formed on both sides is about -200 Pa.
本发明实施例提供的雾化器，与现有技术相比，通过在雾化弹主体1内部临近出气口16的位置设有感应气腔，将气动触发组件3安装于感应气腔中，并在气动触发组件3的两侧分别形成第一腔室18和第二腔室33，第一腔室18内的压强为标准大气压，第二腔室33通过气道34与出气口16连通。用户通过出气口16抽吸气溶胶时，在抽吸形成的负压作用下，第二腔室33内形成负压，使得气动触发组件3的两侧形成气压差，气动触发组件3感应到气压差后便可触发雾化芯2启动雾化工作。由于将气动触发组件3设置在临近出气口16的位置，缩短了连通第二腔室33与出气口16的气道34的长度，减小了气道34的
吸阻，可显著提高气动触发组件3被抽吸气流触发的灵敏度，有效防止气动触发组件3失灵。此外，将气动触发组件3设置在临近出气口16的位置，可避免由雾化器底部泄漏的雾化液或冷凝液对气动触发组件3产生侵蚀，造成气动触发组件3失灵或损坏，从而可延长气动触发组件3的使用寿命。Compared with the prior art, the atomizer provided in the embodiment of the present invention is provided with a sensing air cavity at a position near the air outlet 16 inside the atomizer bomb body 1, and the pneumatic trigger assembly 3 is installed in the sensing air cavity, and a first chamber 18 and a second chamber 33 are formed on both sides of the pneumatic trigger assembly 3, respectively. The pressure in the first chamber 18 is the standard atmospheric pressure, and the second chamber 33 is connected to the air outlet 16 through an airway 34. When the user inhales the aerosol through the air outlet 16, a negative pressure is formed in the second chamber 33 under the action of the negative pressure formed by the suction, so that an air pressure difference is formed on both sides of the pneumatic trigger assembly 3. After the pneumatic trigger assembly 3 senses the air pressure difference, it can trigger the atomizer core 2 to start the atomization work. Since the pneumatic trigger assembly 3 is arranged at a position near the air outlet 16, the length of the airway 34 connecting the second chamber 33 and the air outlet 16 is shortened, and the airway 34 is reduced. The suction resistance can significantly improve the sensitivity of the pneumatic trigger component 3 to be triggered by the suction airflow, and effectively prevent the pneumatic trigger component 3 from malfunctioning. In addition, the pneumatic trigger component 3 is arranged near the air outlet 16 to prevent the atomized liquid or condensed liquid leaking from the bottom of the atomizer from corroding the pneumatic trigger component 3, causing the pneumatic trigger component 3 to malfunction or be damaged, thereby extending the service life of the pneumatic trigger component 3.

Since the air outlet 16 is arranged at the top of the atomizer bomb body 1, and the pneumatic trigger assembly 3 is arranged at a position on the atomizer bomb body 1 near the air outlet 16, on the one hand, the distance between the pneumatic trigger assembly 3 and the air outlet 16 can be greatly shortened, the length of the airway 34 can be reduced, and the sensitivity of the pneumatic trigger assembly 3 can be significantly improved. On the other hand, the atomized liquid or condensate leaked from the bottom of the atomizer can be prevented from eroding the pneumatic trigger assembly 3. In addition, the air outlet 16 and the pneumatic trigger assembly 3 are arranged at the top of the atomizer bomb body 1, and the air inlet 17 is arranged at the bottom of the atomizer bomb body 1, so that the distance between the air inlet 17 and the air outlet 16 is much larger than the distance between the pneumatic trigger assembly 3 and the air outlet 16, so that the air in the airway 34 is preferentially sucked into the air outlet 16 by the suction negative pressure, which is beneficial to improve the sensitivity of the pneumatic trigger assembly 3.

Under the negative pressure caused by the user's suction, part of the air in the second chamber 33 is sucked to the air outlet 16 through the air passage 34, and negative pressure can be formed in the second chamber 33. At this time, since the pressure in the first chamber 18 is the standard atmospheric pressure, a pressure difference can be formed on both sides of the pneumatic trigger assembly 3, and the pneumatic trigger assembly 3 is After the component 3 senses the air pressure difference, it starts the working state, thereby triggering the atomizer core 2 to start the atomization work.

When the user inhales the aerosol through the air outlet 16, a suction negative pressure can be formed in the air guide channel 19. Under the action of the suction negative pressure, the air in the airway 34 and the aerosol in the atomizing chamber 14 can be sucked to the air outlet 16, thereby ensuring that the second chamber 33 can form a negative pressure quickly, speeding up the response time of the pneumatic trigger assembly 3, and quickly starting the atomizing core of the atomizer.
