Both the inner sleeve 220 and the outer sleeve 230 form the part of the atomization chamber 210 located in the resonant cavity 110, which can be generally understood as that the atomization chamber 210 is relatively independently arranged in the resonant cavity 110, so that the atomization chamber 210 The atomizing medium is also located in the resonant cavity 110, so that the atomizing medium can effectively absorb microwaves in the resonant cavity 110, thereby generating heat and atomizing. Along the direction perpendicular to the axial direction of the atomizer 20 , that is, along the radial direction of the resonator 100 , the part of the outer sleeve 230 located inside the resonator cavity 110 is spaced apart from the resonator 100 , so that the outer sleeve 230 and the resonator 120 form a non-contact relationship.

The atomized medium in the liquid storage chamber 311 is input into the atomized chamber 210 through the transmission hole 3131 .

In some embodiments, the generator 520 is connected to the lower end of the resonator 100 and is located outside the resonator 110 . The generator 520 is used to generate microwaves, and the frequency of the microwaves can be 915MHZ, 2450MHZ or 5800MHZ, etc. When the frequency of the microwaves is 915MHZ, the wavelength of the microwaves is 327.8mm; when the frequency of the microwaves is 2450MHZ, the wavelength of the microwaves is 122.4mm ; When the microwave frequency is 5800MHZ, the microwave wavelength is 51.7mm. The transmission body 510 is used to transmit microwaves generated by the generator 520. The transmission body 510 may be a columnar structure, such as a cylinder or a prism. The transmission body 510 may also be a hollow structure or a solid structure. The lower part of the transmission body 510 is electrically connected to the generating body 520, and the upper part of the transmission body 510 passes through the resonator 100 and is arranged in the resonant cavity 110 and the flow guide cavity 221. The central axes of the resonant cavity 110, the atomization cavity 210 and the transmission body 510 coincide, and along the radial direction of the guide cavity 221, the transmission body 510 and the inner sleeve 220 are spaced apart, that is, the transmission body 510 and the inner sleeve 220 form a non-contact relationship. The length of the part of the transmission body 510 inside the resonant cavity 110 is 8 mm to 70 mm, for example, the specific value of the length may be 8 mm, 50 mm or 70 mm. The diameter of the transmission body 510 is 2mm to 20mm, for example, the specific value of the diameter may be 2mm, 10mm or 20mm.

If the microwave of the generator 520 is directly transmitted into the resonant cavity 110 without the transmission body 510, on the one hand, in order to meet the propagation conditions of the microwave, the diameter of the resonant cavity 110 will be appropriately increased, thereby increasing the size of the resonant body 100. And the size of the whole atomizer is not conducive to the miniaturization design of the atomizer. On the other hand, even though the microwave energy propagates in the resonant cavity 110, the attenuation of the microwave energy along the axial direction of the resonant cavity 110 is relatively large, so that the transmission distance of the microwave along the axial direction of the resonant cavity 110 is extremely limited, resulting in the microwave being confined near the resonant cavity 110. The position of the generating body 520 is not conducive to the effective transmission of microwaves into the atomizing chamber 210 .

In the above-mentioned embodiment, by setting the transmission body 510 pierced in the resonant cavity 110, first, the resonant cavity 110 with a smaller diameter can also meet the microwave propagation conditions, thereby realizing the miniaturization of the nebulizer 20 and ensuring the mist The carburetor 20 is easy to carry and store. The second is that the microwave energy is transported to the end of the transmission body 510 along the transmission body 510, so by setting the length of the transmission body 510 reasonably, the restriction of microwave energy attenuation is eliminated, so that the microwave can reach any position in the axial direction of the resonant cavity 110, ensuring that the microwave effectively transported into the atomization chamber 210.

Referring to FIG. 4 , in some embodiments, taking the axial direction of the atomizer 20 as a reference, the end of the transmission body 510 located in the resonant cavity 110 is marked as the first end 511 , and the end of the resonator 100 away from the generating body 520 (that is, the upper end) is denoted as the second end portion 132, and the first end portion 511 and the second end portion 132 are set apart along the axial distance, that is, the first end portion 511 and the second end portion 132 are on the axis. There is a set distance L upward. The wavelength of the microwave is denoted as λ, the diameter of the resonant cavity 110 is denoted as a, and the diameter of the transmission body 510 is denoted as b, where λ>π(a+b). Through the setting of the above-mentioned set distance L and the relationship between the microwave wavelength and the diameter of the resonant cavity 110 and the diameter of the transmission body 510, it is difficult for the microwave to reach from the first end 511 of the transmission body 510 through the space within the above-mentioned set distance. The second end 132 , that is, the space where it is difficult for microwaves to enter the resonant cavity 110 is located at the set interval, so as to further prevent the microwave in the resonant cavity 110 from leaking from the second end 132 .

When the atomizer 20 is working, the liquid supply pump can be started first, so that the liquid supply pump inputs a set amount of atomizing medium from the liquid storage chamber 311 to the atomization chamber 210 . Then the user can inhale at the upper end of the inhalation channel 411 , and the generating body 520 will automatically start immediately after sensing the suction force of the user, and the microwave generated by the generating body 520 will propagate in the resonant cavity 110 through the transmitting body 510 . After the microwave enters the atomizing cavity 210 through the inner sleeve 220 , there is high-frequency friction between the polar molecules in the atomizing medium to generate heat, so that the atomizing medium is atomized to form an aerosol. During the suction process, the external air enters the atomization chamber 210 through the air intake channel 421 to carry the aerosol, so that the aerosol enters the inhalation channel 411 from the atomization chamber 210 through the vent hole 222 and the flow guide chamber 221 in turn, and finally makes the The aerosol in the inhalation channel 411 is absorbed by the user.

If the heating resistor is used to directly heat the atomizing medium, there will be at least the following defects: First, the part of the atomizing medium closer to the heating resistor will form a high-temperature area due to more heat absorbed, while the atomizing medium is farther away from the heating resistor. The far part forms a low-temperature area due to less heat absorption, so that there is a certain gradient in the heat distribution on the atomizing medium, which eventually leads to uneven heating of the atomizing medium. At the same time, the existence of the high-temperature area will cause the atomization medium to carbonize and form a burnt smell, and the existence of the low-temperature area will make the atomization medium unable to atomize because the atomization temperature has not been reached. The second is that the heating resistor will continue to heat up, and the heating resistor will be cracked in a high-temperature environment to produce harmful substances. At the same time, the heating resistor will also have the risk of fusing under high-temperature operation, thereby affecting the service life of the heating resistor. The third is that the heating resistor is in direct contact with the atomizing medium, so that there is carbon deposit on the surface of the heating resistor, which will generate odorous gas during repeated heating, thus affecting the taste of the pump. Moreover, the heating resistor is usually made of metal material, so that the heavy metal elements in the heating resistor are not absorbed by the user, so as to affect the safety of suction.

For the atomizer 20 in the above embodiment, one is to heat the atomizing medium by microwaves, and the polar molecules of the atomizing medium in each area of the atomizing chamber 210 simultaneously generate heat and atomize through high-frequency friction, and the atomizing medium All parts are heated evenly, eliminating the gradient distribution of heat, ensuring that the temperature of each part of the atomization medium is consistent, avoiding carbonization of the atomization medium due to high temperature, and improving the aerosol suction taste. The second is that the generating body 520 has the function of generating microwaves, and the transmitting body 510 has the function of transmitting microwaves, so that the transmitting body 510 and the generating body 520 themselves will not generate heat, thereby preventing high temperature from forming fusing damage to the transmitting body 510 and the generating body 520, improving The service life of the transmission body 510 and the generation body 520; also prevent the transmission body 510 from producing harmful substances under the action of high temperature, and improve the taste and safety of the aerosol inhalation. The third is that the transmission body 510 and the generator 520 do not form direct contact with the atomization medium, which prevents the formation of carbon deposits on the surface of the transmission body 510 and the generation of odorous gases, and also prevents the heavy metal elements in the transmission body 510 from entering the aerosol, further improving the aerosol. Smoking taste and safety of sol.

The present invention also provides an electronic atomization device 10, the electronic atomization device 10 includes an atomizer 20 and a power supply assembly 30, the atomizer 20 can be detachably connected to the power supply assembly 30, so that the power supply assembly 30 can be cycled multiple times use. The power supply assembly 30 includes a battery 31 and a control circuit board 32. The battery 31 is electrically connected to the control circuit board 32 and the generator 520. The battery 31 is used to supply power to the generator 520, so as to provide energy for the generator 520 to generate microwaves. The control circuit board 32 is used to control the power supply of the battery 31 to the generating body 520. When the control circuit board 32 stops the battery 31 from supplying power to the generating body 520, the generating body 520 will not be able to generate microwaves, so the atomizing medium will not be atomized. When the user sucks on the nozzle part 410, the control circuit board 32 can make the battery 31 supply power to the generating body 520, so that the atomized base is atomized to form an aerosol.
