[0003] In the atomizers currently on the market, the internal environment of the atomizer is relatively closed, which makes it easy for heat to accumulate inside the shell during the use of the atomizer. Therefore, when the atomizer is used for a long time, the atomizer component of the atomizer will continue to heat up to atomize the atomized material. The heating of the atomizer component will cause the outer surface of the shell to heat up. When the temperature outside the shell is too high, it will burn the user, thereby reducing the user's atomization experience. Utility Model Content

[0035] The present application provides an electronic atomization device 1000, which is used to generate heat to atomize an object to be atomized 000, so that the object to be atomized 000 is heated to form an atomized gas. The embodiment of the present application takes a portable atomization device as an example of the electronic atomization device 1000 to elaborate on the technical solution of the present application in detail. The portable atomization device has the characteristics of being easy to carry, strong applicability, and a wide range of applications. It should be understood that the electronic atomization device 1000 to which the technical solution of the present application is applicable includes but is not limited to medical atomizers, household atomizers, micro atomizers, etc., and the present application does not limit this.

[0036] In one embodiment, the electronic atomization device 1000 includes an atomizer 100 and a power supply 300. The atomizer 100 is electrically connected to the power supply 300. The atomizer 100 is used to carry the object to be atomized 000. The atomizer 100 is used to generate heat under the action of the electric energy of the power supply 300 so that the object to be atomized 000 carried on the atomizer 100 is heated and atomized.

[0037] See also Figure 2 , Figure 2 It is a cross-sectional view of an atomizer provided in one embodiment of the present application.

[0038] The present application provides an atomizer 100, taking the atomizer 100 as an electromagnetic heating non-combustion type atomizer 100 as an example. The atomizer 100 is used for electromagnetically heating and atomizing an object to be atomized 000, and the atomizer 100 includes a housing 10 and an atomizing assembly 30, the atomizing assembly 30 is accommodated in the housing 10, and the atomizing assembly 30 is used to carry and electromagnetically heat and atomize the object to be atomized 000.

[0039] In this embodiment, the housing 10 has a connected accommodating chamber 11 and a through hole 12. The housing 10 is cylindrical, and the accommodating chamber 11 extends along the axial direction of the housing 10. The through hole 12 is arranged at one end of the housing 10 along the axial direction. The through hole 12 is used for the atomizer assembly 30 to be provided with the atomizer 000. The gap between the through hole 12 and the atomizer 000 is used for inputting airflow. The atomizer assembly 30 is accommodated in the accommodating chamber 11. The atomizer assembly 30 is used for electromagnetic heating to atomize the atomizer 000 carried in the atomizer assembly 30. The outer wall of the atomizer assembly 30 and the inner wall of the housing 10 are spaced and form an airflow channel 50. The airflow channel 50 connects the through hole 12 and the inside of the atomizer assembly 30, so that the airflow input from the through hole 12 flows into the inside of the atomizer assembly 30, and the airflow entering the inside of the atomizer assembly 30 flows out through the atomizer 000.

[0040] The atomizer 100 provided by the present application is provided with an interval between the outer wall of the atomizer assembly 30 and the inner wall of the housing 10 to form an airflow channel 50, and the airflow channel 50 communicates with the through hole 12 and the inside of the atomizer assembly 30, so that the airflow outside the atomizer 100 flows into the inside of the atomizer assembly 30 through the airflow channel 50. On the one hand, the airflow flowing in the airflow channel 50 can cool and dissipate the inner wall of the housing 10, so that the temperature on the outer wall of the housing 10 of the atomizer 100 is relatively low, which is conducive to reducing the risk of scalding the user due to overheating of the outside of the housing 10, and is convenient for the user to hold. Moreover, the airflow flowing in the airflow channel 50 can cool and dissipate the inner wall of the housing 10 and the outer wall of the atomizer assembly 30, which can reduce the occurrence of overheating of the atomizer assembly 30, and is conducive to improving the stability of the operation of the atomizer assembly 30 and the service life of the atomizer assembly 30. On the other hand, after the airflow passes through the airflow channel 50 and the through hole 12, the airflow will absorb the temperature of the outer wall of the atomizer assembly 30. When the airflow enters the interior of the atomizer assembly 30, the temperature of the heating position of the atomizer assembly 30 will not drop too much, so that the atomizer assembly 30 does not need to consume more energy to increase the temperature of the heating position, which is beneficial to reducing the thermal power consumption of the atomizer assembly 30 when heating and atomizing the same type of atomized material 000.

[0041] See also Figure 2 In one embodiment, the housing 10 includes a heat-insulating material. By making the housing 10 of the heat-insulating material, the heat conduction from the atomizing assembly 30 to the outer wall of the housing 10 can be reduced, so that the temperature on the outer wall of the housing 10 of the atomizer 100 is relatively low, which is beneficial to reduce the risk of scalding the user due to overheating of the outer shell 10, and is convenient for the user to hold.

[0042] It is understandable that the thermal insulation materials include but are not limited to ceramic fiber blanket, aluminum silicate felt, alumina, silicon carbide fiber, aerogel felt, glass wool, expanded perlite, micro-nano thermal insulation, etc., and the present application does not impose any restrictions on this.

[0043] See also Figure 2In one embodiment, the atomization assembly 30 includes a bracket 31 and a heating component 33. The bracket 31 is accommodated in the accommodating chamber 11, and the outer wall of the bracket 31 and the inner wall of the housing 10 are spaced to form an airflow channel 50. The heating component 33 is installed on the bracket 31, and the heating component 33 is used to carry the atomized object 000 passing through the through hole 12 of the housing 10, and the heating component 33 is also used for electromagnetic heating to atomize the atomized object 000. The bracket 31 is provided with an air inlet 311 and a mounting port 312, the air inlet 311 is used to communicate with the airflow channel 50, and the mounting port 312 is used for the atomized object 000 passing through the through hole 12 of the housing 10 to pass through the heating component 33. Among them, part of the heating component 33 is arranged on the outer wall of the bracket 31, and part of the heating component 33 is arranged in the bracket 31, and the heating component 33 arranged in the bracket 31 is used to generate heat to atomize the atomized object 000. The airflow outside the shell 10 enters the airflow channel 50 through the through hole 12, then enters the heating component 33 arranged in the bracket 31 through the air inlet 311, and finally flows out through the atomized object 000, so that the atomizer 100 atomizes the atomized object 000 and forms atomized gas.

[0044] The atomizer 100 provided in this embodiment forms an airflow channel 50 by setting the outer wall of the bracket 31 and the inner wall of the shell 10 at intervals, and the heating component 33 is installed on the bracket 31. The heating component 33 is used to carry the object to be atomized 000 passing through the through hole 12 of the shell 10. The heating component 33 is also used for electromagnetic heating to atomize the object to be atomized 000. The airflow outside the shell 10 enters the airflow channel 50 through the through hole 12, and then enters the heating component 33 through the air inlet 311, and finally flows out through the object to be atomized 000. In this process, after the airflow flows through the airflow channel 50 and the air inlet 311, the airflow will absorb the temperature of the outer wall of the bracket 31. When the airflow enters the interior of the heating component 33, the temperature at the heating position of the heating component 33 will not drop too much, so that the heating component 33 does not need to consume more energy to increase the temperature at the heating position, which is conducive to reducing the overall thermal power consumption of the atomizer 100 when heating and atomizing the same type of object to be atomized 000.

[0045] See also Figure 2 In one embodiment, the air inlet 311 and the mounting port 312 are arranged at opposite ends of the bracket 31 in the axial direction, and the mounting port 312 is arranged near the through hole 12 relative to the air inlet 311. The through hole 12 is used for the atomized object 000 to pass through the mounting port 312, and the opening size of the through hole 12 is larger than the opening size of the mounting port 312, so that the outer wall of the atomized object 000 and the inner wall of the through hole 12 are arranged at intervals.

[0046] The atomizer 100 provided in this embodiment is provided at opposite ends of the axial direction of the bracket 31 through the air inlet 311 and the mounting port 312. The mounting port 312 is provided near the through hole 12 relative to the air inlet 311, so that the airflow outside the housing 10 enters the airflow channel 50 through the through hole 12, then enters the heating component 33 through the air inlet 311, and finally flows out through the atomized object 000, so that the airflow flow path of the atomizer 100 is shorter, which can reduce the occurrence of the breath holding phenomenon. Moreover, the opening size of the through hole 12 is larger than the opening size of the mounting port 312, so that after the atomized object 000 passes through the through hole 12 and the mounting port 312, the atomized object 000 is spaced apart from the inner wall of the through hole 12, so that the airflow outside the housing 10 enters the airflow channel 50 through the gap between the inner wall of the through hole 12 and the outer wall of the atomized object 000.

[0047] See also Figure 2 , Figure 3 and Figure 4 , Figure 3 This is a diagram showing the effect of an atomizer provided in one embodiment of the present application atomizing an object to be atomized and an atomizer provided in the prior art atomizing an object to be atomized. Figure 4 This is a structural diagram of a coil wound around a bracket provided in the first embodiment of the present application.

[0048] In one embodiment, the heating component 33 includes a heating tube 331 and a coil 333. The coil 333 is used to generate a variable current after being powered on, and the heating tube 331 is used to generate heat through electromagnetic induction in the variable current formed by the coil 333. The heating tube 331 is a magnetic part, and the heating tube 331 is accommodated in the bracket 31. The coil 333 is wound outside the bracket 31. The coil 333 is used to circulate a variable current. The variable current circulated in the coil 333 is used to heat the magnetic heating tube 331 to atomize the atomized object 000.

[0049] The atomizer 100 provided in this embodiment is provided with a coil 333 of the heating component 33 wound outside the bracket 31, and a heating tube 331 of the heating component 33 is accommodated in the bracket 31, so that the magnetic heating tube 331 is heated and atomized by the changing current flowing in the coil 333. When the airflow outside the housing 10 flows through the airflow channel 50, the airflow will take away the heat generated by the coil 333 and the heat transferred to the bracket 31 by the heating tube 331. On the one hand, the surface temperature of the outer wall of the housing 10 can be reduced, which is conducive to reducing the risk of scalding the user due to overheating of the outer shell 10. On the other hand, after the airflow takes away the heat generated by the coil 333 and the heat transferred to the bracket 31 by the heating tube 331, the airflow with a certain temperature flows into the heating tube 331 through the airflow inlet, and the airflow will not cause the temperature in the heating tube 331 to drop sharply, so that the heating tube 331 does not need to consume more energy to increase the temperature at the heating position, which is conducive to reducing the overall thermal power consumption of the atomizer 100 when heating and atomizing the same type of atomized object 000. Further reading Figure 3 It can be seen that, in the atomizer 100 provided in this embodiment, when the user inhales, the temperature in the heating tube 331 drops sharply, which is smaller than the axial amplitude of the temperature of the atomizer 100 provided in the prior art when the user inhales. That is, when heating and atomizing the same type of atomized object 000, the heating tube 331 in the atomizer 100 provided in this embodiment needs less power consumption to generate heat to the temperature required for atomization, which can reduce the heat power consumption of the heating tube 331, and further reduce the overall heat power consumption of the atomizer 100.

[0050] See also Figure 2 and Figure 4 In one embodiment, the outer wall of the heating tube 331 is spaced apart from the inner wall of the bracket 31, and the heating tube 331 has a heating cavity 3311, which is used to accommodate the atomized object 000. The heating cavity 3311 penetrates the heating tube 331, and the heating cavity 3311 is connected to the air inlet 311 and the mounting port 312. The airflow outside the housing 10 enters the airflow channel 50 through the through hole 12, and then enters the heating cavity 3311 of the heating tube 331 arranged in the bracket 31 through the air inlet 311, and finally flows out through the atomized object 000.

[0051] In the atomizer 100 provided in this embodiment, the heating tube 331 will generate heat to atomize the atomized substance 000 under the action of the energized coil 333. By setting the outer wall of the heating tube 331 and the inner wall of the bracket 31 at a distance, the heat transfer from the heating tube 331 to the bracket 31 can be reduced, the temperature of the bracket 31 can be reduced, and the heat transfer from the bracket 31 to the shell 10 can be reduced, so that the temperature on the outer wall of the shell 10 of the atomizer 100 is relatively low, which is beneficial to reducing the risk of scalding the user due to overheating of the outer side of the shell 10, and is convenient for the user to hold.

[0052] See also Figure 2 In one embodiment, the side of the coil 333 facing away from the bracket 31 is spaced from the inner wall of the housing 10. The spacing between the coil 333 and the inner wall of the housing 10 can reduce the heat conduction to the housing 10 caused by the heating of the coil 333 after being energized, so that the temperature on the outer wall of the housing 10 of the atomizer 100 is relatively low, which is conducive to reducing the risk of scalding the user due to overheating of the outer shell 10, and is convenient for the user to hold.

[0053] See also Figure 2 and Figure 5 , Figure 5 This is a structural diagram of a coil wound around a bracket provided in the second embodiment of the present application.

[0054] In one embodiment, a spiral winding groove 313 is provided on the outer wall of the bracket 31, and the coil 333 is wound in the winding groove 313. By providing the spiral winding groove 313 on the outer wall of the bracket 31, the stability of the coil 333 wound on the bracket 31 is improved. Moreover, the coil 333 is wound in the spiral winding groove 313, so that the distance between the coil 333 and the inner wall of the shell 10 is larger, which is conducive to further reducing the heat conduction of the coil 333 to the shell 10 after the coil 333 is powered on, so that the temperature on the outer wall of the shell 10 of the atomizer 100 is relatively low, which is conducive to reducing the risk of scalding the user due to overheating of the outer shell 10, and is convenient for the user to hold.

[0055] See also Figure 2 and Figure 6 , Figure 6 This is a structural diagram of a coil wound around a bracket provided in the third embodiment of the present application.

[0056] In one embodiment, a ventilation groove 314 is provided on the outer wall of the bracket 31, and the ventilation groove 314 extends along the axial direction of the bracket 31. By providing the ventilation groove 314 extending along the axial direction on the outer wall of the bracket 31, the airflow channel 50 can be made larger, and the problem of suffocation caused by the airflow channel 50 being too small can be reduced. At the same time, by providing the ventilation groove 314, the contact area between the airflow in the airflow channel 50 and the outer wall of the bracket 31 is larger, which is conducive to improving the cooling and heat dissipation effect of the bracket 31.

[0057] See also Figure 2 and Figure 4In one embodiment, the coil 333 is a spiral coil 333, and the side of the coil 333 facing away from the bracket 31 contacts the inner wall of the shell 10, and the outer wall of the bracket 31, the coil 333 and the inner wall of the shell 10 form an airflow channel 50, and the airflow channel 50 is spiral. The spiral coil 333 is wound around the bracket 31, and the coil 333 is sandwiched between the inner wall of the shell 10 and the outer wall of the bracket 31, and the outer wall of the bracket 31, the coil 333 and the inner wall of the shell 10 form a spiral airflow channel 50. On the one hand, the airflow flowing in the airflow channel 50 can cool and dissipate the inner wall of the shell 10, so that the temperature on the outer wall of the shell 10 of the atomizer 100 is relatively low, which is conducive to reducing the risk of scalding the user due to overheating of the outer shell 10, and is convenient for the user to hold. Moreover, the airflow flowing in the airflow channel 50 can cool down and dissipate the inner wall of the housing 10 and the outer wall of the atomizer assembly 30, which can reduce the occurrence of overheating of the atomizer assembly 30, and is beneficial to improving the working stability of the atomizer assembly 30 and the service life of the atomizer assembly 30. On the other hand, after the airflow flows through the airflow channel 50 and the through hole 12, the airflow will absorb the temperature of the outer wall of the atomizer assembly 30. When the airflow enters the interior of the atomizer assembly 30, the temperature of the heating position of the atomizer assembly 30 will not be reduced too much, so that the atomizer assembly 30 does not need to consume more energy to increase the temperature of the heating position, which is beneficial to reduce the thermal power consumption of the atomizer assembly 30 when heating and atomizing the same type of atomized object 000.

[0058] See also Figure 2 and Figure 7 , Figure 7 This is a structural diagram of a coil wound around a bracket provided in the fourth embodiment of the present application.

[0059] In one embodiment, there are multiple coils 333, and the multiple coils 333 are wound outside the bracket 31. For example, the number of coils 333 is two, and the two coils 333 are wound on the bracket 31 along the axial direction of the bracket 31. Through the arrangement of multiple coils 333, the positions of the heating tube 331 corresponding to different coils 333 can heat and atomize the atomized object 000 separately, which is conducive to improving the heating and atomization control effect of the heating tube 331 on the atomized object 000.

[0060] It can be understood that in some other embodiments, the coils 333 can be radially stacked. By controlling the number of different coils 333 that are energized, the heating power of the heating tube 331 can be adjusted, which is beneficial for the user to control the atomizer 100 to perform heating and atomization of different types of atomized objects 000 with different heating powers, which is beneficial to improving the atomization effect of the atomized object 000 in the atomizer 100.

[0061] See also Figure 8 , Figure 8 It is a cross-sectional view of another atomizer provided in one embodiment of the present application.

[0062] In one embodiment, the coil 333 is formed by winding a heating wire, the heating wire has a hollow cavity 3331, one end of the heating wire passes through the housing 10 and is exposed to the outside of the housing 10, and the other end of the heating wire is arranged in the airflow channel 50 and communicates with the airflow channel 50. Specifically, one end of the heating wire passes through the housing 10 and is exposed to the outside of the housing 10, and the other end of the heating wire first passes through the housing 10 and is exposed to the outside of the housing 10, and then the other end of the heating wire passes through the housing 10 again, enters the inside of the housing 10, and communicates with the airflow channel 50.

[0063] The atomizer 100 provided in this embodiment forms a hollow tube shape by forming the heating wire of the coil 333, so that a part of the airflow can enter the airflow channel 50 through the hollow cavity 3331 of the coil 333. Since the airflow flows inside the hollow cavity 3331 of the coil 333, the airflow can cool down and dissipate the heat of the coil 333 that is powered on and heated. In addition, the heat transfer from the coil 333 to the housing 10 is reduced, so that the temperature on the outer wall of the housing 10 of the atomizer 100 is relatively low, which is conducive to reducing the risk of scalding the user due to overheating of the outer shell 10, and is convenient for the user to hold.

[0064] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
