[0023] The application will be described in further detail below with reference to the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustration of the application and do not limit the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0024] Reference to "embodiments" in this application means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the application can be combined with other embodiments.

[0025] In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the fact that they can be realized by those skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection claimed by the application.

[0026] The application describes an electronic atomizer that can be used to atomize an aerosol generating substrate by an energy conversion member. The aerosol generating substrate is a material used to generate an aerosol. It can generally consist of at least one chemical substance capable of generating an aerosol, such as a flavorant, a drug or other active ingredient. The aerosol generating substrate can be activated by the energy conversion member through heating or other means, thereby releasing an aerosol for various applications, such as medical, cosmetic, cleaning, etc.

[0027] In some embodiments, the aerosol generating substrate can be water or at least include water.

[0028] Please refer to Figure 1 , Figure 1 A schematic diagram of the frame of an electronic atomizer in some embodiments of the application is shown. The electronic atomizer 100 can include an atomization control circuit 101. It can be understood that the electronic atomizer 100 can also include other structures such as a housing, etc., and is not limited to the embodiments listed here. The electronic atomizer 100 can carry other structures in the electronic atomizer 100 through the housing, etc., and can be held by the user to achieve use, or can be used to hold the aerosol generating substrate through the housing, etc. The specific structure and composition of the electronic atomizer 100 are not described here.

[0029] The atomization control circuit 101 can include energy conversion pieces, such as the heating atomization piece 10 and the ultrasonic atomization piece 20. The heating atomization piece 10 can perform an atomization process on the first aerosol generating substrate by heating, and the ultrasonic atomization piece 20 can perform an atomization process on the second aerosol generating substrate using ultrasonic waves. The electronic atomizer 100 can be used to mix the atomized first aerosol generating substrate and the atomized second aerosol generating substrate to form an aerosol to be output.

[0030] The present application can meet various needs of users by performing atomization processes on the first aerosol generating substrate and the second aerosol generating substrate, respectively, and mixing them.

[0031] In addition, compared to the heating atomization process, the ultrasonic atomization process has lower energy consumption. Furthermore, in cooperation with the heating atomization piece 10 and the ultrasonic atomization piece 20, the ultrasonic atomization piece 20 performs an atomization process on the second aerosol generating substrate using ultrasonic waves, which can reduce the energy consumption of the atomization process using heating and improve the endurance of the electronic atomizer 100.

[0032] In some embodiments, the aerosol generating substrate after the heating atomization process has a unique smell compared to the aerosol generating substrate after the ultrasonic atomization process, which can further make it necessary to perform the heating atomization process using the heating atomization piece 10, but can not make it necessary to perform the ultrasonic atomization process using both the heating atomization piece 10 and the ultrasonic atomization piece 20.

[0033] In some embodiments, the heating atomization piece 10 can include a heating resistor to generate heat by the heating resistor and perform a heating atomization process on the aerosol generating substrate.

[0034] In some embodiments, the ultrasonic atomization piece 20 can be an electronic component using the principle of ultrasonic atomization (a technology for atomizing a liquid into small molecule gas mist using ultrasonic wave energy), which can perform an atomization process on the aerosol generating substrate using ultrasonic waves. In some embodiments, the ultrasonic atomization piece 20 can include at least a component capable of generating high-frequency mechanical vibrations under the action of a high-frequency electrical signal. For example, a structure made of piezoelectric ceramic material, of course, it can also be other, not described here.

[0035] In some embodiments, in the electronic atomizer 100, the first aerosol generating substrate and the second aerosol generating substrate can be respectively stored in two chambers, and the electronic atomizer 100 can have a mixing chamber or a mixing channel, and the atomized first aerosol generating substrate and the atomized second aerosol generating substrate can be mixed in the mixing chamber or the mixing channel. In some scenarios, the mixing channel can be directly communicated with the outside of the electronic atomizer 100, and thus the aerosol to be output can be directly delivered to the outside of the electronic atomizer 100. In some scenarios, the mixing channel can be directly communicated with the outside of the electronic atomizer 100, and the aerosol to be output formed in the mixing chamber can be delivered to the outside of the electronic atomizer 100 through the mixing channel. In some scenarios, both ends of the mixing channel are communicated with the outside of the electronic atomizer 100, and when a negative pressure is generated at one end of the mixing channel, gas at the other end of the mixing channel will rush into the mixing channel and push the aerosol to be output to the end where the negative pressure is generated. In some scenarios, the electronic atomizer 100 has an air inlet channel, and the air inlet channel can be communicated with the two chambers, and the two chambers can also be communicated with the mixing channel.

[0036] When a negative pressure is generated at one end of the mixing channel, gas enters from the air inlet channel, pushes the atomized first aerosol generating substrate and the atomized second aerosol generating substrate to the mixing channel, and then pushes the aerosol to be output to the end where the negative pressure is generated. In some scenarios, the electronic atomizer 100 has an air inlet channel, and the air inlet channel can be communicated with the mixing chamber, and the mixing chamber can also be communicated with the mixing channel, and when a negative pressure is generated at one end of the mixing channel, gas enters from the air inlet channel, pushes the atomized first aerosol generating substrate and the atomized second aerosol generating substrate to the mixing channel, and then pushes the aerosol to be output to the end where the negative pressure is generated.
