Description

Atomizer and aerosol generating device having the same

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on June 12, 2023, with application number 202321486740.1 and application name “A nebulizer with an anti-sticking core and an aerosol generating device having the same,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure belongs to the field of aerosol generating devices, and particularly relates to an atomizer and an aerosol generating device having the same. Background Art

[0003] An aerosol generating device is an electronic product that utilizes an atomizing component to heat an aerosol matrix and atomize it into an aerosol state for users to use. At the same time, the aerosol generated by the aerosol generating device does not contain other harmful components such as tar and suspended particulate matter. Therefore, it has a wide range of application markets. In order to enhance explosive power and reduction, the aerosol generating devices currently on the market generally adopt the method of increasing the output power of the atomizing core. The problem caused by this is that the temperature in the atomizing area is high. If the heat in the atomizing area cannot be transferred out in time, the core will be burnt, which will greatly reduce the taste of the aerosol and seriously affect the user's smoking experience.

[0037] Please refer to Figure 1. The atomizer provided by the embodiment of the present disclosure includes a shell 1, a suction nozzle 11 is formed at the upper end of the shell 1, an oil cup 2 is provided in the shell 1, an atomization tube 3 connected to the suction nozzle 11 is provided in the oil cup 2, an oil inlet portion 31 is provided on the atomization tube 3, an atomization core 4 is provided in the atomization tube 3, and a phase change material layer 5 is provided on at least a portion of the outer side of the atomization tube 3 between the suction nozzle 11 and the atomization core 4. The phase change material layer 5 is used to adjust the temperature of the atomization tube 3.

[0038] With the above structure, in practical applications, using the atomizer of the disclosed embodiment, the oil cup 2 is used to store aerosol matrix. The aerosol matrix stored in the oil cup 2 can flow into the atomizer tube 3 through the oil inlet 31. When powered, the atomizer core 4 generates heat and heats the aerosol matrix flowing into the atomizer tube 3, atomizing it into a mist-like aerosol. When the user draws at the mouthpiece 11, the aerosol flows along the atomizer tube 3 to the mouthpiece 11, where it can be inhaled. Since the atomizer core 4 generates heat when powered, heat is transferred from the atomizer core 4 to the atomizer tube 3. The phase change material layer 5, located on at least a portion of the outer surface of the atomizer tube 3, absorbs the heat transferred to the atomizer tube 3, preventing the atomizer core 4 from burning due to heat accumulation. Furthermore, the heat absorption effect of the phase change material layer 5 effectively reduces the temperature of the aerosol entering the user's mouth, resulting in a milder taste and alleviating the problem of burning the mouth at the mouthpiece 11. Furthermore, reducing the heat can reduce the temperature difference between the inside and outside of the housing 1, thereby reducing the generation of condensation in the atomizing tube 3, and further ensuring the taste of the aerosol.

[0039] Specifically, an interlayer 32 is provided on at least a portion of the outer side of the atomizer tube 3. The phase change material layer 5 is disposed between the interlayer 32 and the atomizer tube 3. A receiving cavity 51 is formed between the interlayer 32 and the outer wall of the atomizer tube 3. This allows the phase change material layer 5 to be conveniently disposed within the receiving cavity 51 and allows for better contact between the phase change material layer 5 and the atomizer tube 3, thereby absorbing heat transferred to the atomizer tube 3.

[0040] As a preferred embodiment, in this embodiment, the interlayer 32 is arranged around the outer circumference of the atomizing tube 3. The phase change material layer 5 is arranged between the interlayer 32 and the atomizing tube 3 and is also arranged around the outer circumference of the atomizing tube 3. This ensures that the phase change material layer 5 can absorb heat from the atomizing tube 3 in all directions.

[0041] Specifically, one end of the interlayer 32 is connected to the atomizer tube 3, and a sealing ring 33 is provided between the other end of the interlayer 32 and the atomizer tube 3. The phase change material layer 5 can be loaded into the accommodating cavity 51 from the other end of the interlayer 32 and then sealed by the sealing ring 33, so that the phase change material layer 5 can be relatively firmly positioned in the accommodating cavity 51.

[0042] Optionally, the phase change material layer 5 is made of graphite oxide, a reducing agent and an organic phase change material. In this way, the phase change material layer 5 has a good heat storage and heat absorption capacity through phase change, and can better absorb the heat at the atomizing tube 3.

[0043] Generally, when the ambient temperature is higher than the phase change temperature of the organic phase change material, the organic phase change material stores heat. When the ambient temperature is lower than the phase change temperature of the organic phase change material, the organic phase change material releases the stored energy.

[0044] Specifically, the oil inlet 31 is located at the lower end of the interlayer 32. The atomizer core 4 is located within the oil inlet 31. Because heat is transferred upward, the atomizer core 4 is located within the oil inlet 31 and at the lower end of the interlayer 32. This means that the phase change material layer 5 is located at the upper end relative to the atomizer core 4, allowing the phase change material layer 5 to better absorb the heat transferred from the atomizer core 4 to the atomizer tube 3.

[0045] Specifically, a liquid guide 41 is provided within the oil inlet 31. The atomizer core 4 is housed within this guide 41. This guide 41 absorbs and stores the aerosol matrix that flows from the oil inlet 31 into the atomizer tube 3. The heat generated by the atomizer core 4 heats and atomizes the aerosol matrix absorbed and stored within the guide 41 into a mist-like aerosol. The phase change material layer 5 absorbs the heat transferred to the atomizer tube 3, reducing heat accumulation in the guide 41 and preventing the core from becoming sticky.

[0046] Specifically, the housing 1 includes an outer shell 12 and a bottom cover 13 provided at the lower end of the outer shell 12. The nozzle 11 is formed at the upper end of the outer shell 12. The outer shell 12 and the bottom cover 13 together constitute the housing 1, which is convenient for disassembly and installation of the atomizer.

[0047] Specifically, an upper sealing gasket 21 is provided at the upper end of the oil cup 2. A lower sealing gasket 22 is provided at the lower end of the oil cup 2. The upper sealing gasket 21 and the lower sealing gasket 22 provide a seal at the upper and lower ends of the oil cup 2 to prevent leakage of the aerosol matrix stored in the oil cup 2.

[0048] Specifically, a liquid absorption pad 23 is provided at the lower end of the suction nozzle 11. The liquid absorption pad 23 can absorb the condensation formed at the lower end of the suction nozzle 11, preventing the condensation from being inhaled into the mouth of the user and choking the user, thereby ensuring the health and safety of the user.

[0049] 1-3 , the aerosol generating device provided in this embodiment includes the atomizer as in the embodiment of this case, and also includes a host. The host is arranged at the lower end of the shell 1, and the atomizing core 4 is electrically connected to the host.

[0050] In one embodiment, the main unit includes a bottom shell 61, a bracket 62 provided on the bottom shell 61, a battery cell 63 provided on the bracket 62, and a main board 64 electrically connected to the battery cell 63. The atomizer core 4 is electrically connected to the main board 64. The battery cell 63 supplies power to the atomizer core 4. The main board 64 controls the working state of the atomizer core 4.

[0051] Specifically, an air inlet 65, an indicator hole 66 and a socket 67 are also provided on the bottom shell 61. The air inlet 65 is connected to the outside of the aerosol generating device. The air inlet 65 is connected to the atomizing tube 3. The air inlet 65 is used to realize the internal and external gas exchange of the aerosol generating device. An indicator light 68 and a socket 69 are respectively provided in the indicator hole 66 and the socket 67. The indicator light 68 and the socket 69 are both electrically connected to the main board 64. The indicator light 68 is used to display the working status of the aerosol generating device, and the socket 69 is used to connect an external charger, so that the battery cell 63 can be charged, thereby realizing the recyclable use of the aerosol generating device.

[0052] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present disclosure, and such modifications or substitutions should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
