Description

Atomizer and aerosol generating device using the same

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 14, 2023, with application number 202321517567.7 and titled “A Nebulizer and Aerosol Generating Device Using the Same”. The entire contents of the above application are incorporated into this application by reference. Technical Field

[0002] The present application belongs to the technical field of aerosol generating devices, and relates to an atomizer and an aerosol generating device using the same. Background Art

[0003] In recent years, due to consumers' continued attention to health concepts, the development of electronic atomization devices has become increasingly rapid. Electronic atomization devices are electronic devices that use heating wires to heat the aerosol matrix and atomize it into an aerosol state for users to use. Because electronic atomization devices do not contain harmful substances, they have been deeply loved by people since their inception.

[0004] The nebulizer, the core structure of an aerosol generator, primarily consists of a liquid storage device and an atomizer. The aerosol matrix in the liquid storage device is introduced into the atomizer's atomizer chamber, where it is heated and atomized into a gas. The gas then passes through the atomizer chamber and the airway before flowing out for the user to inhale. Because the gas is hot, the temperature difference between the two is significant when it strikes the inner wall of the flow channel during its flow, forming condensate. This condensate easily flows upward along the airflow direction and creeps to the outer opening of the airway tube, causing the user to inhale the condensate into their mouth during inhalation, impacting the user experience. SUMMARY OF THE INVENTION

[0005] This application mainly addresses the technical problem that during the operation of the aerosol generating device, the condensed liquid generated easily flows upward along the airflow direction and crawls to the external tube opening of the airway tube, thereby causing the user to inhale the condensed liquid into the mouth when inhaling, affecting the user experience.

[0006] In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a nebulizer, which includes a liquid storage component, an atomization component and an air guide component. The liquid storage component is connected to the atomization component, and the air guide component is located inside the atomization component; the air guide component includes a channel for discharging mist, and a bone structure extends inward on the wall of the channel.

[0007] According to another aspect of the present application, an aerosol generating device is provided, comprising the aerosol generating device. Beneficial effects

[0008] The nebulizer provided in the present application has a liquid storage component for storing aerosol matrix, which is connected to the nebulization component. The nebulization component can atomize the aerosol matrix, and the atomized aerosol matrix is ​​discharged through the channel. In this process, due to the high temperature of the gas, when the gas hits the inner wall of the flow channel during the flow, the temperature difference between the two is large, thereby forming condensate. The condensate can easily flow upward along the direction of the airflow and crawl to the external tube mouth of the airway tube, thereby allowing the user to inhale the condensate into the mouth when inhaling.

[0022] Example 1

[0023] This embodiment provides a nebulizer, as shown in Figure 1-10, the nebulizer includes a liquid storage component 1, an atomization component 2 and an air guide component 3, the liquid storage component 1 is connected to the atomization component 2, and the air guide component 3 is located in the atomization component 2; the air guide component 3 includes a channel 31 for discharging mist, and a bone structure 32 extends inward from the wall of the channel 31.

[0024] Specifically, the liquid storage component 1 is provided with a liquid storage chamber, an oil guide hole and a through air outlet channel, and the atomization component 2 is provided with an atomization chamber, an oil inlet hole and an air inlet channel. The atomization component 2 is embedded in the liquid storage component 1 and is sealed with the liquid storage component 1; the liquid storage chamber, the oil guide hole, the oil inlet hole and the atomization chamber are connected in sequence to allow the aerosol in the liquid storage chamber to be introduced into the atomization chamber; the atomization component 2 is used to atomize the aerosol matrix in the atomization chamber into a gas form.

[0025] During specific use, the liquid storage component 1 is used to store the aerosol matrix, which is connected to the atomizing component 2. The atomizing component 2 can atomize the aerosol matrix, and the atomized aerosol matrix is ​​discharged through the channel. In this process, due to the high temperature of the gas, when the gas hits the inner wall of the flow channel during the flow, the temperature difference between the two is large, thereby forming condensate. The condensate can easily flow upward along the direction of the airflow and crawl to the external tube opening of the airway tube, thereby allowing the user to inhale the condensate into the mouth during inhalation. In this embodiment, the air guide component 3 is cleverly nested within the liquid storage component 1. The air guide component 3 includes a channel 31 for discharging mist. The wall surface of the channel 31 extends inwardly with a skeleton structure 32. In this way, when the condensate flows upward along the direction of the airflow, it is blocked by the skeleton structure 32 in the channel 31 and the effect of its own gravity, causing the condensate to flow back, improving the condensate inlet during the consumer's inhalation process and the condensate flowing out of the airway tube opening when the product is turned over after inhalation.

[0026] In a specific embodiment, along the axial direction of the channel 31 , the cross-section of the bone structure 32 is triangular.

[0027] Specifically, one side of the triangle (fixed side) is fixed on the inner wall of the channel 31, and the other two sides extend into the channel 31. Along the axial direction of the channel 31, the height of the extended end is lower than the height of the fixed side. In this way, on the one hand, the triangular skeleton structure 32 can be firmly set in the channel 31, and on the other hand, the lower height extended end is facing the inside of the channel 31 to avoid affecting the flow of gas.

[0028] In a specific embodiment, a plurality of the frame structures 32 are provided, and the plurality of frame structures 32 are evenly distributed along the circumference of the channel 31 at the same height. In addition, the ends of the plurality of frame structures 32 facing the interior of the channel 31 do not contact each other, leaving gaps for gas flow.

[0029] In a specific embodiment, the atomizing assembly 2 includes a ceramic heating element 21 , a bracket unit 22 and a base unit 23 . The ceramic heating element 21 is located in the bracket unit 22 , and the bracket unit 22 is assembled with the base unit 23 .

[0030] In a specific embodiment, the bracket unit 22 includes a silicone bracket 221 and a bracket body 222 . The silicone bracket 221 and the bracket body 222 are nested, and the ceramic heating element 21 is located inside the bracket body 222 .

[0031] Specifically, the silicone bracket 221 is first installed in the bracket body 222 , the silicone pad 223 is then installed in the bracket body 222 , and finally the ceramic heating element 21 is installed in the bracket body 222 to form the bracket unit 22 .

[0032] In a specific embodiment, the base unit 23 includes an electrode 231, a connecting piece 232, oil-absorbing cotton 233 and a sealing ring 234. The electrode 231 is pressed into the connecting piece 232, the oil-absorbing cotton 233 is assembled in the connecting piece 232, and the sealing ring 234 is sleeved on the connecting piece 232.

[0033] Specifically, the electrode 231 is first pressed into the connecting piece 232 , the oil-absorbing cotton 233 is then installed into the connecting piece 232 , and the sealing ring 234 is then inserted into the connecting piece 232 to form the base unit 23 .

[0034] In a specific embodiment, the liquid storage assembly 1 includes an oil bin 11 and a suction nozzle 12 located above the oil bin 11 , and the channel 31 is located in the oil bin 11 and communicates with the suction nozzle 12 .

[0035] In a specific embodiment, the sealing ring 234 is an O-ring.

[0036] In traditional atomizers, the condensate generated during the puffing process can easily flow upward along the direction of the airflow and crawl to the outer tube opening of the airway tube, causing the condensate to be easily inhaled into the mouth during puffing; while in the atomizer provided in this embodiment, when the user puffs, when the condensate flows upward along the direction of the airflow, it is blocked by the skeleton structure in the channel and the effect of its own gravity, so that the condensate flows back, improving the condensate inlet during the consumer's puffing process and the condensate flows out of the airway tube opening when the product is turned upside down after puffing, thereby preventing the consumer from inhaling the condensate into the mouth during the puffing process, creating a good experience.
