[0028] Please refer to Figures 2 to 4 The present application embodiment discloses an atomizer, comprising: a shell 1, an atomization assembly 2 and a liquid storage cavity 3 arranged in the shell 1, the atomization assembly 2 comprising an exhaust pipe 23, the atomization assembly 2 being provided with an air inlet hole 21 at the lower end, and the exhaust pipe 23 having an exhaust passage 22 for connecting the air inlet hole 21 and the liquid storage cavity 3.

[0029] Specifically, when the atomizer starts to work, the heating element in the atomization assembly 2 heats the liquid substance on the atomization core, causing it to evaporate rapidly to form an aerosol. At the same time, due to the heating and evaporation, a pressure difference is generated in the liquid storage cavity 3. At this time, external air enters the atomizer through the air inlet hole 21 and flows upward along the exhaust passage 22 of the exhaust pipe 23. In the process of flowing, the air gradually enters the liquid storage cavity 3 and exchanges with the gas in the liquid storage cavity 3, thereby balancing the pressure difference in the liquid storage cavity 3. In this way, the exhaust passage 22 ensures the stability of the pressure in the liquid storage cavity 3, prevents the phenomenon of liquid leakage caused by uneven pressure, and ensures the normal operation of the atomizer. At the same time, without the need to additionally set an atomization outer cover to balance the pressure in the liquid storage cavity 3, the cost of materials and assembly is greatly reduced.

[0030] As shown in Figures 2-4 , the exhaust pipe 23 is provided with at least two exhaust grooves 231 and at least two liquid injection holes 232. The inlet of the air inlet hole 21 communicates with the exhaust groove 231, the exhaust groove 231 communicates with the liquid injection hole 232, and the liquid injection hole 232 communicates with the liquid storage cavity 3.

[0031] Specifically, when the user inhales, external air enters the exhaust pipe 23 through the air inlet hole 21 and enters the liquid injection hole 232 through the exhaust groove 231 to enter the liquid storage cavity 3 for air exchange. At the same time, the aerosol substrate in the liquid storage cavity 3 enters the atomization assembly 2 and is heated and atomized into steam under the action of the heating element. The steam mixes with the entering air in the exhaust pipe 23 to form an aerosol, which is finally inhaled by the user. Under the action of this mode, not only can it help prevent the occurrence of liquid leakage and seepage, but also can improve the taste and smoking experience of the aerosol.

[0032] Specifically, in this embodiment, the number of exhaust grooves 231 and exhaust holes is two. In other embodiments, the corresponding number can be set according to the specific circumstances.

[0033] As shown in Figure 2 and Figure 4 , the at least two exhaust grooves 231 are uniformly distributed along the inner wall of the exhaust pipe 23.

[0034] Specifically, by uniformly distributing the exhaust grooves 231, the flow path and speed of the gas in the atomizer can be optimized, which helps to improve the atomization efficiency, reduce the noise and prolong the service life of the atomizer.

[0035] As shown in Figure 2 and Figure 4 , the exhaust groove 231 is a straight-line groove, and the exhaust groove 231 extends from the air inlet hole 21 to the liquid injection hole 232.

[0036] Specifically, the straight groove is simple and direct in design, which is conducive to the smooth flow of gas. In this embodiment, the cross-sectional shape of the straight groove can be rectangular, trapezoidal or other shapes suitable for gas flow, depending on the design requirements and processing capabilities.

[0037] In some embodiments, the exhaust groove 231 can also be designed as a spiral or multi-section to increase the flow path and residence time of the gas in the tube, thereby better achieving pressure differential balance.

[0038] As shown in Figures 2-3 , the bottom of the exhaust pipe 23 is provided with a gear part 24.

[0039] Specifically, the gear part 24 is connected with the heating element in the atomization assembly 2, which is used to fix the heating element to prevent the heating element from moving unstably in the atomizer, thereby improving the stability of the atomizer.

[0040] As shown in Figure 2 , the atomizer also includes a suction nozzle 4, which is connected with the upper end of the atomization assembly 2, and a sealing part 5 is arranged at the connection between the suction nozzle 4 and the atomization assembly 2.

[0041] Specifically, the sealing part 5 is located at the connection between the suction nozzle 4 and the atomization assembly 2, and its main function is to prevent the aerosol from leaking during transmission. This not only improves the use efficiency of the atomization device, but also avoids the user from inhaling too much air or impurities; the sealing part 5 is usually made of soft, high-temperature-resistant and corrosion-resistant materials, such as silica gel or rubber, and its shape matches the shape of the connection to ensure the sealing effect.

[0042] As shown in Figures 2-3 , the atomization assembly 2 is provided with an air inlet 25 below, which is in communication with the air inlet hole 21.

[0043] Specifically, when the user inhales, the external air enters the inside of the atomization device through the air inlet 25 and the air inlet hole 21, providing necessary air supplement for the atomization process, which helps to promote the evaporation and atomization of the liquid, forming an aerosol for inhalation.

[0044] As shown in Figure 2 , the atomization assembly 2 is provided with a bracket 6 outside, and the bracket 6 is provided with a mounting groove 61, and the atomization assembly 2 is mounted in the mounting groove 61.

[0045] Specifically, the bracket 6 serves as an external support structure of the atomization assembly 2, mainly playing a role of fixing, protecting and connecting, ensuring that the atomization assembly 2 can be stably installed at the required position and preventing it from being impacted or damaged externally. The shape of the bracket 6 is usually designed according to the specific size and installation requirements of the atomization assembly 2 to ensure that it can tightly wrap and fix the atomization assembly 2, and in terms of material, a solid, corrosion-resistant and high-temperature-resistant material such as metal (such as stainless steel, aluminum alloy) or high-strength plastic should be selected.

[0046] As shown in Figure 2 The bottom of the shell 1 is provided with a base 7, and the base 7 is located below the bracket 6. The base 7 and the inner side of the bracket 6 are provided with a power supply assembly 8, the power supply assembly 8 is connected with the atomization assembly 2, and the power supply assembly 8 includes two electrodes 81. The bracket 6 is also provided with at least two insertion slots 62, and the electrodes 81 are inserted into the insertion slots 62.

[0047] Specifically, in this embodiment, the number of insertion slots 62 is two, and in other embodiments, the position and number of insertion slots 62 are arranged according to the design requirements of the power supply assembly 8. The electrodes 81 are fixed in the insertion slots 62 by insertion, ensuring tight connection with other parts of the power supply system, so as to realize stable transmission of electric energy. When the atomization device is started, the power supply assembly 8 starts to work, and the electric energy is transmitted to the atomization assembly 2 through the electrodes 81. After receiving the electric energy, the atomization assembly 2 converts the liquid into aerosol by using the heat energy or other effects generated by the electric energy, and the aerosol is then inhaled by the user through the mouthpiece 4 and other components.

[0048] According to another aspect of the present application, the utility model embodiment also provides an aerosol generating device, which comprises the above-mentioned atomizer.

[0049] Specifically, the aerosol generating device is a device that converts liquid or solid particles into tiny particles (i.e. aerosol) suspended in gas in a specific way. The aerosol generating device contains the atomizer as its core component, and in other embodiments, other necessary components can also be equipped to complete the generation and output of aerosol, including power supply system, control system and safety protection components, etc. When the user starts the aerosol generating device, the power supply system provides electric energy for the atomizer, and the control system controls the atomization assembly 2 to start working according to the preset parameters, heats and converts the liquid in the liquid storage cavity into aerosol, which is then inhaled by the user through the mouthpiece 4 component. During the whole process, the safety protection component continuously monitors the working state to ensure the safe operation of the equipment.

[0050] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the protection scope of the present application.
