For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] See also Figures 1 to 3The present application provides an electronic atomization device 1, which includes an atomizer 200 and a power supply device 100. The atomizer 200 is provided with an atomization channel 201. The power supply device 100 includes a shell. The shell 10 is formed with a plug-in cavity 11. At least a portion of the atomizer 200 can be plugged into the plug-in cavity 11. The shell 10 is also provided with an air inlet 12. The air inlet 12 is located on the side of the bottom wall of the plug-in cavity 11 away from the plug-in cavity 11. The bottom wall of the plug-in cavity 11 is convexly provided with an air guide boss 21 facing the plug-in cavity 11. The air guide boss 21 is provided with an air guide through hole 211. When the atomizer 200 is plugged into the plug-in cavity 11, the air guide boss 21 is plugged into the atomization channel 201 and is sealed and connected to the atomization channel 201 so that the air guide through hole 211 is connected to the atomization channel 201. By providing the gas-guiding protrusion 21, when the atomizer 200 is plugged into the plug-in cavity 11 of the power supply device 100, a part of the gas-guiding protrusion 21 is plugged into the atomizing channel 201 of the atomizer 200. The gas-guiding protrusion 21 can also increase the contact area between itself and the inner wall of the atomizing channel 201, and prevent the airflow from leaking from the gap between the gas-guiding protrusion 21 and the atomizing channel 201. In this way, the gas-guiding through hole 211 in the gas-guiding protrusion 21 can form an input channel for the external airflow together with the air inlet hole 12, and the gas-guiding through hole 211 can guide the airflow, thereby preventing the airflow from diffusing to the plug-in cavity 11. The airflow needs to enter the atomizing channel 201 of the atomizer 200 through the gas-guiding through hole 211, so that the airflow enters the atomizing channel 201 without passing through the surface of the atomizer 200. When the atomizer 200 leaks, the airflow cannot flow through the gap between the atomizer 200 and the plug-in cavity 11, so the condensed liquid or atomized medium carried by the airflow can be prevented from flowing to the mating surface of the atomizer 200 and the power supply device 100. In this way, the air guide protrusion 21 seals the leaking liquid, thereby solving the risk of leaking liquid or oil at the connection part between the atomizer 200 and the power supply device 100, and improving the reliability of the electronic atomizer 1 and the user experience. Figure 1 , Figure 2 and Figure 4It can be understood that the housing 10 of the power supply device 100 has an opening, and the housing 10 is generally cylindrical or rod-shaped, and a housing space is formed in the housing 10, in which electronic components such as the battery 50, the control circuit board, and the airflow sensor 40 can be placed, and a battery holder 30 can be provided in the housing 10 to facilitate fixing the battery 50. In addition to accommodating the battery 50, the housing space also reserves a certain space, which is connected to the opening of the housing 10 to facilitate plugging the atomizer 200. Therefore, the space for plugging the atomizer 200 is formed as a plug-in cavity 11. When the atomizer 200 is plugged into the plug-in cavity 11, the atomizer 200 can be electrically connected to the battery 50 or the control circuit board, so that the atomizer 200 is powered by the battery 50 to power it on. The depth of the atomizer 200 inserted into the plug-in cavity 11 can be flexibly set according to the product design of the electronic atomization device 1. For example, the atomizer 200 can be entirely set in the plug-in cavity 11, or a portion of the atomizer 200 can be set in the plug-in cavity 11, which is not limited here. Therefore, the mating surface of the atomizer 200 and the power supply device 100 includes the bottom surface of the atomizer 200, the outer wall surface of the atomizer 200 located in the plug-in cavity 11, the inner wall surface of the plug-in cavity 11, and the top surface of the battery holder 30.

[0033] In some embodiments, the power supply device 100 further includes a first seal 20, which is disposed at the bottom of the plug-in cavity 11 to seal the plug-in cavity 11, the air inlet 12 is located on the side of the first seal 20 away from the plug-in cavity 11, and the air guide protrusion 21 is disposed on the first seal 20. By providing the first seal 20, after the external air enters the housing 10 from the air inlet 12, on the one hand, the first seal 20 is used to seal the bottom of the plug-in cavity 11, thereby blocking the airflow from diffusing to the plug-in cavity 11, and the airflow needs to enter the atomization channel 201 of the atomizer 200 through the air guide through hole 211, so that the airflow can enter the atomization channel 201 without passing through the surface of the atomizer 200 located at the plug-in cavity 11. By adopting the solution provided in the present application, the bottom surface of the atomizer 200 can be separated from the top surface of the battery holder 30 by using the first seal 20, and the bottom surface of the plug-in cavity 11 can be sealed, so that after the airflow enters the shell 10 from the air inlet hole 12, it enters the atomization channel 201 through the air guide hole 211. Of course, in other examples, the air guide boss 21 may not use the first seal 20, but is directly set on the top end surface of the battery holder 30. After the external airflow enters the shell 10 through the air inlet hole 12, it can enter the air guide hole 211 through the battery holder 30. By setting the end surface of the battery holder 30 facing the plug-in cavity 11 to be interference-fitted with the inner wall of the shell 10, it can also play the effect of blocking the airflow from flowing into the gap between the inner wall of the plug-in cavity 11 and the surface of the atomizer 200, thereby guiding the airflow from the air guide hole 211 into the atomization channel 201.

[0034] In some embodiments, see Figure 7 The first sealing member 20 includes a main body 22, an air guide protrusion 21 is protruding from the main body 22, and an extension portion 23 is further provided on the periphery of the main body 22. The extension portion 23 extends in a direction opposite to the protrusion direction of the air guide protrusion 21, and the extension portion 23 abuts against the inner wall of the housing 10. By abutting the extension portion 23 against the inner wall of the housing 10, the contact area between the first sealing member 20 and the inner wall of the housing 10 can be increased, thereby improving the sealing effect of the first sealing member 20. Optionally, the extension portion 23 can be continuously provided along the circumference of the main body 22.

[0035] In some embodiments, a sealing lip 231 is also provided on the periphery of the extension 23, and the sealing lip 231 is extended in a direction away from the plug-in cavity 11. By providing the sealing lip 231 protruding from the periphery of the extension 23, the mutual abutment force between the extension 23 and the housing 10 can be increased, and the sealing effect can be further improved. Of course, in other examples, an annular protrusion can also be provided on the inner wall of the housing 10 to increase the mutual abutment force between the inner wall of the housing 10 and the extension 23, which can also play a role in improving the sealing effect.

[0036] In some embodiments, the first seal 20 is a flexible member. For example, the first seal 20 can be made of silicone or other polymer materials to have a certain elasticity. In this way, the first seal 20 can better adapt to the size and shape of the housing 10. By utilizing the flexible characteristics of the first seal 20, the first seal 20 and the inner wall of the housing 10, the atomization channel 201 and the battery holder 30 can form an interference fit to ensure the sealing effect.

[0037] In some embodiments, the battery holder 30 is located on the side of the first seal 20 away from the plug-in cavity 11, and the end of the battery holder 30 close to the first seal 20 is provided with a first mounting groove 31, and the extension 23 is clamped in the first mounting groove 31. By using the first mounting groove 31, the contact area between the battery holder 30 and the first seal 20 can be increased, the stability of the first seal 20 installed on the top of the battery holder 30 can be improved, and the sealing effect can be improved. It can be understood that the extension 23 of the first seal 20 is arranged in the gap between the first mounting groove 31 and the inner wall of the shell 10, and the extension 23 is simultaneously abutted against the inner wall of the shell 10 and the battery holder 30, so as to achieve a sealing effect. Specifically, the first mounting groove 31 and the inner wall of the shell 10 can squeeze the extension 23, and the extension 23 has a sealing effect through the squeezing deformation. In particular, when the extension 23 is provided with a sealing lip 231, the sealing lip 231 can improve the sealing effect through the squeezing deformation.

[0038] See also Figures 4 to 6 and Figure 8In some embodiments, the battery holder 30 includes a main body 32, a first mounting groove 31 is arranged on the outer peripheral side of the main body 32, a guide groove 321 is further arranged on the outer peripheral side of the main body 32, the guide groove 321 and the first mounting groove 31 are not connected to each other, the main body 32 is further provided with a guide cavity 322, the guide cavity 322 is connected to the air guide hole 211, one end of the guide groove 321 is connected to the air inlet 12, and the other end is connected to the guide cavity 322. Exemplarily, the guide cavity 322 can be arranged in the middle of the main body 32, the guide cavity 322 can be arranged coaxially with the main body 32, or the guide cavity 322 is eccentrically arranged in the main body 32. This is not limited here. By using the guide groove 321, the gas can be guided to flow along the outer peripheral surface of the main body 32 to reach the guide cavity 322, and the conduction effect between the guide cavity 322 and the air guide hole 211 is used to make the air flow finally flow into the air guide hole 211. On the one hand, the guide groove 321 is provided on the outer peripheral surface of the main body 32, which can make full use of the space of the battery holder 30, making the structure of the battery holder 30 more compact, thereby saving space in the shell 10, which is conducive to the simplification and miniaturization design of the power supply device 100. On the other hand, the air inlet 12 is not directly connected to the air guide hole 211, but is indirectly connected by the guide groove 321 and the guide cavity 322. In this way, even if leakage occurs in the atomization channel 201, when the condensed liquid or the atomized medium leaks along the air guide channel, the buffer storage function of the guide cavity 322 can be used to prevent the condensed liquid from directly leaking to the air inlet 12, thereby improving the reliability and experience of the user when using the electronic atomization device 1.

[0039] In some embodiments, the shell 10 is provided with two air inlet holes 12, and the two air inlet holes 12 are symmetrically arranged along the axis of the shell 10. The guide groove 321 is arranged around the outer peripheral side of the main body and is connected to the two air inlet holes 12 respectively. The side wall of the guide cavity 322 is provided with two guide inlets 3221, and the guide inlet 3221 is connected to the guide cavity 322 and the guide groove 321. The two guide inlets 3221 are symmetrically arranged along the axis of the main body 32, and the guide inlet 3221 is staggered with the air inlet 12, and the connecting line of the two guide inlets 3221 intersects with the connecting line of the two air inlets 12. By providing two air inlet holes 12, the air intake area of ​​the electronic atomization device 1 can be increased, the mixing effect of the air and the aerosol after the atomization medium is atomized is improved, and it is ensured that the electronic atomization device 1 has a good taste. The two air inlet holes 12 are symmetrically arranged along the axis of the shell 10, which can improve the uniformity and stability of the air intake. By setting the guide inlet 3221 and the air inlet 12 to be staggered, the external air needs to pass through a section of the guide groove 321 in the process from the air inlet 12 to the guide inlet 3221, so as to control the air intake speed within a reasonable range. When the atomization channel 201 leaks, the condensate or atomized medium also needs to pass through a section of the guide groove 321 in the process of leaking from the guide cavity 322 to the air inlet, which extends the path of the leaked liquid flow and further reduces the risk of leakage. The line connecting the two air inlets 12 intersects with the line connecting the two guide inlets 3221, so that no matter which air inlet 12 the air flow enters the housing 10, it can flow roughly evenly from the guide grooves 321 on both sides of the air inlet to the corresponding guide inlet 3221, thereby improving the uniformity of the air flow. Exemplarily, the line connecting the two air inlets 12 and the line connecting the two guide inlets 3221 can be arranged perpendicular to each other.

[0040] In some embodiments, the power supply device 100 further includes a second seal 70, which is disposed on the outer peripheral side of the main body 32, and along the axial direction of the main body 32, the second seal 70 is located on the side of the air inlet 12 away from the first seal 20. The power supply device 100 further includes an airflow sensor 40, and the main body 32 is provided with a mounting cavity 324, and the airflow sensor 40 is disposed in the mounting cavity 324, and the mounting cavity 324 is connected to the guide cavity 322 through the guide groove 321. The airflow sensor 40 is used to sense the change of the airflow pressure in the housing 10, so as to control the start and stop of the atomizer 200. Specifically, the mounting cavity 324 is connected to the guide cavity 322 through the guide groove 321, and then connected to the atomization channel 201. When the user inhales through the atomization channel 201, a negative pressure is formed in the mounting cavity 324, and when the airflow sensor 40 detects that the negative pressure reaches a preset value, the atomizer 200 is controlled to start. There is a certain gap between the battery holder 30 and the shell 10, and the shell 10 also has a certain gap after the battery holder 30 and the battery 50 are set. The second seal 70 can be used to seal the space below the air inlet 12, thereby avoiding the installation cavity 324 from being connected to the space in these gaps. The installation cavity 324 is connected to the guide cavity 322 only through the guide groove 321. In this way, the volume of the space connected to the installation cavity 324 can be reduced, and the effect of the installation cavity 324 detecting negative pressure can be improved, thereby improving the startup sensitivity of the airflow sensor 40 and improving the performance of the electronic atomization device 1.

[0041] Exemplarily, the second sealing member 70 may be a flexible silicone ring.

[0042] In some embodiments, the main body 32 is further provided with a second mounting groove 323, and the second sealing member 70 is arranged in the second mounting groove 323. The first mounting groove 31, the guide groove 321, and the second mounting groove 323 are arranged in parallel with each other and are arranged in sequence along the axial direction of the main body 32. The second sealing member 70 is installed by using the second mounting groove 323, which can play a good fixing role on the second sealing member 70 and improve the reliability of the use of the second sealing member 70. By arranging the three grooves of the first mounting groove 31, the guide groove 321, and the second mounting groove 323 in parallel, the space of the main body 32 of the battery holder 30 can be fully utilized, making its structure simpler and more compact.

[0043] In some embodiments, the power supply device 100 further includes a battery 50 and a probe 60, the battery 50 is arranged on the battery holder 30, one end of the probe 60 is electrically connected to the battery 50, the first sealing member 20 is provided with a probe through hole 24, the other end of the probe 60 is penetrated through the probe through hole 24, so as to be electrically connected to the electrode 202 of the atomizer 200, and the probe through hole 24 and the air guide through hole 211 are not connected to each other. By providing the probe 60, it is possible to ensure that the atomizer 200 and the power supply device 100 are stably electrically connected. The probe through hole 24 is provided on the first sealing member 20, and the sealing performance of the first sealing member 20 is not destroyed while ensuring that the probe 60 can be exposed to the first sealing member 20, so as to avoid leakage of airflow from the position of the probe through hole 24. It is understandable that the probe through hole 24 and the probe 60 can also be fitted by interference fit to ensure the sealing performance of the first sealing member 20.
