Description

Atomizers and aerosol generating equipment Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an atomization device and an aerosol generating device. Background Art

[0002] Cigarette smoke contains harmful substances such as tar. Long-term inhalation of these substances can cause serious harm to the human body. To overcome the harmful effects of cigarette smoke, low-risk alternatives such as e-cigarettes with e-liquids and heat-not-burn e-cigarettes have emerged. Traditional e-cigarettes typically consist of a cigarette holder and a cartridge. The cigarette holder powers the cartridge, which generates aerosol for the user to inhale.

[0003] However, some unscrupulous third-party manufacturers are now producing generic cartridges, considered knockoffs, that are compatible with genuine e-cigarette holders. These generic cartridges, often marketed as lower-priced, disrupt the market and harm the interests of legitimate e-cigarette manufacturers. Furthermore, generic cartridges are generally of questionable quality and contain excessive levels of harmful substances, which harms consumer health and can damage e-cigarettes.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Please refer to Figures 1, 2 and 3. In the first aspect, in some embodiments, the present application provides an aerosol generating device 10, which includes an atomizing device 11, a sealing member 12 and a power supply device 13. The power supply device 13 is electrically connected to the atomizing device 11, and the atomizing device 11 is used to generate an aerosol. As shown in Figures 2, 5 and 6, the atomizing device 11 is provided with a plug-in protrusion 810, and the power supply device 13 is provided with a plug-in recess 410. As shown in Figure 4, a second air channel 411 is provided in the plug-in recess 410, and the sealing member 12 is provided in the second air channel 411. As shown in Figures 2 and 3, a first air channel 812 is provided in the plug-in protrusion 810, and the plug-in protrusion 810 is used to be inserted into the plug-in recess 410 and puncture the sealing member 12 to achieve conduction between the second air channel 411 and the first air channel 812.

[0040] Please refer to Figures 7 and 8. In the second aspect, in some embodiments, the present application provides an aerosol generating device 10, which includes an atomizing device 11, a sealing member 12 and a power supply device 13. The power supply device 13 is electrically connected to the atomizing device 11, and the atomizing device 11 is used to generate an aerosol. As shown in Figure 7, the atomizing device 11 is provided with a plug-in recess 410, and as shown in Figure 8, the power supply device 13 is provided with a plug-in protrusion 810. A second air passage 411 is provided in the plug-in recess 410, and the sealing member 12 is provided in the second air passage 411. A first air passage 812 is provided in the plug-in protrusion 810, and the plug-in protrusion 810 is used to be inserted into the plug-in recess 410 and puncture the sealing member 12 to achieve conduction between the second air passage 411 and the first air passage 812.

[0041] The above-mentioned aerosol generating device 10 can at least achieve the following beneficial effects: when the atomizing device 11 is connected to the power supply device 13, the power supply device 13 can supply power to the atomizing device 11, and the atomizing device 11 can atomize the atomizing medium to generate an aerosol for the user to inhale. The realization of this process requires the second air channel 411 to be connected to the first air channel 812. In this application, a seal 12 is provided in the second air channel 411 of the plug-in recess 410. The seal 12 can seal the second air channel 411, and the aerosol generating device 10 of this application can be considered a genuine product. When the atomizing device 11 is connected to the power supply device 13, as shown in FIG3, the plug-in protrusion 810 is inserted into the second air channel 411 of the plug-in recess 410 and punctures the seal 12. At this time, the second air channel 411 can be connected to the first air channel 812, thereby allowing the atomizing device 11 to generate aerosol normally. On the contrary, if the atomizing device 11 of a copycat product is used in conjunction with the power supply device 13, the seal 12 cannot be punctured, and the seal 12 will still close the second air channel 411. The second air channel 411 and the first air channel 812 cannot be connected, and the atomizing device 11 cannot normally take in air, and the normal supply of aerosol cannot be achieved. In short, the aerosol generating device 10 of the present application has a role in preventing wildcards through its ingenious structural design, and has a simple structure and low implementation cost. Among them, the atomizing medium can refer to a material that can be atomized to provide aerosol components under certain conditions. For example, the atomizing medium can be one or more of smoke oil, smoke liquid, tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes.

[0042] Furthermore, in some embodiments, as shown in FIG2 , the atomizing device 11 is provided with the plug-in protrusion 810 and the atomizing chamber 910, and the atomizing chamber 910 is connected to the first air channel 812. As shown in FIG4 and FIG6 , the power supply device 13 is provided with the plug-in recess 410, and the sealing member 12 covers and seals the second air channel 411. As shown in FIG4 , the sealing member 12 covers the second air channel 411 to achieve a sealing effect. When the plug-in protrusion 810 is inserted into the second air channel 411 of the plug-in recess 410 and the sealing member 12 is punctured, the second air channel 411 is connected to the first air channel 812, and the gas can be transported to the atomizing chamber 910 connected to the first air channel 812, thereby achieving the normal supply of aerosol.

[0043] Furthermore, in some embodiments, the seal 12 is made of silicone, that is, the seal 12 is a silicone sealing sheet, that is, a sheet-shaped seal 12 made of silicone, which has low material cost, light and thin structure, can meet the sealing requirements, and is easily punctured by the plug-in protrusion 810.

[0044] Furthermore, in some embodiments, the thickness of the silicone sealing sheet is 0.01 mm-0.1 mm.

[0045] Furthermore, in some embodiments, the thickness of the silicone sealing sheet is 0.05 mm.

[0046] 2 , in some embodiments, the end edge of the plug-in protrusion 810 is chamfered. This structural setting allows the end of the plug-in protrusion 810 to be sharper, making it easier to pierce the seal 12.

[0047] Referring to Figure 4 , in some embodiments, the inner circumference of the second air passage 411 is provided with abutting ribs 412, which are configured to abut against the outer circumference of the plugging protrusion 810. When the plugging protrusion 810 is inserted into the second air passage 411 of the plugging recess 410, the abutting ribs 412 abut against the outer circumference of the plugging protrusion 810, creating a sealing effect and increasing the friction between the two, thereby ensuring a more secure connection.

[0048] Furthermore, in some embodiments, the abutment rib 412 can be an elastic abutment rib 412, that is, it can have a certain elastic deformation ability. When the plug-in protrusion 810 is inserted, the abutment rib 412 can be deformed to adapt to the shape and size of the plug-in protrusion 810.

[0049] 4 , in some embodiments, the abutting rib 412 is provided in a ring shape along the circumference of the plug-in protrusion 810. Such a structural arrangement can further enhance the connection reliability and sealing effect between the plug-in protrusion 810 and the plug-in recess 410.

[0050] Furthermore, as shown in Figure 4 , in some embodiments, the number of the abutting ribs 412 is set to multiple, and the multiple abutting ribs 412 are spaced apart. For example, in the embodiment shown in Figure 4 , the multiple abutting ribs 412 are spaced apart along the axial direction of the second air channel 411. This structural arrangement can further improve the connection reliability and sealing effect between the plug-in protrusion 810 and the plug-in recess 410.

[0051] Referring to FIG. 1 , in some embodiments, the power supply device 13 includes a tube body 100, a circuit board 200, a control assembly, and a power supply assembly 500. The power supply assembly 500 is disposed within the tube body 100 and is used to power the atomization device 11.

The control assembly includes a microphone 300 and a bracket 400. The circuit board 200 and the microphone 300 are both disposed within the bracket 400. The circuit board 200 and the microphone 300 are electrically connected. The microphone 300 is used to detect changes in air pressure or airflow to determine whether the user has performed a puffing operation. The side of the bracket 400 facing away from the power supply assembly 500 is provided with the insertion recess 410. The side of the bracket 400 provided with the insertion recess 410 and the inner peripheral surface of the tube body 100 form an insertion slot 710. The insertion slot 710 is used to receive the atomizing device 11. The insertion slot 710 can accommodate the atomizing device 11 and restrain the atomizing device 11, thereby improving the connection reliability between the atomizing device 11 and the power supply device 13.

[0052] Referring to FIG. 2 , in some embodiments, the atomizer device 11 includes a mouthpiece 600, a housing 700, a base 800, and an atomizer core 900. The atomizer core 900 is disposed within the housing 700 and surrounds an atomizer chamber 910. The base 800 and the mouthpiece 600 are disposed at opposite ends of the housing 700. The base 800 is provided with a plug-in protrusion 810 on a side of the base 800 facing away from the atomizer core 900. The mouthpiece 600 is provided with a suction port 610, which communicates with one end of the atomizer chamber 910, and the other end of the atomizer chamber 910 communicates with the first airway 812. A user can inhale aerosol from the atomizer chamber 910 through the suction port 610.

[0053] In some embodiments, the aerosol generating device 10 is a split-type electronic cigarette. In other words, the aerosol generating device 10 can be considered a cartridge-type electronic cigarette, the atomizing device 11 can be a cigarette cartridge, and the power supply device 13 can be a cigarette rod with a power supply. The atomizing device 11 can be separated from the power supply device 13 by an external force. The atomizing device 11 can be directly pulled out from one end of the power supply device 13, that is, the cigarette cartridge can be pulled out from one end of the cigarette rod. For the user, the atomizing device 11 and the power supply device 13 can be easily disassembled and assembled, and the atomizing device 11 can be replaced.
