[0035] See also Figure 1-Figure 6, the electronic atomizer provided in this embodiment is now described. The electronic atomizer 100 in this embodiment includes an atomizer 1, a main control unit 3 and an airflow sensor 31. The main control unit 3 and the atomizer 1 are matched in a detachable manner, such as the main control unit 3 is fixed to the bottom or side of the atomizer 1 by snaps, threads, adhesives, or magnetic suction. The atomizer 1 includes a shell 11, a mounting seat 12, an atomization module 13 and a sealing silicone 18. The shell 11 can be a special-shaped oil cup with an opening at one end. A suction portion 111 extends upward from one end of the shell 11. The cross-section of the suction portion 111 is elliptical, which is adapted to the shape of the human mouth. The sealing silicone 18 is sealed at the opening, and the mounting seat 12 is embedded in the bottom of the sealing silicone 18. The mounting seat 12 has an upper surface and an oppositely arranged lower surface. The bottom surface of the mounting seat 12 exposed to the outside of the housing 11 is configured as the lower surface, and thus the surface opposite to the lower surface and embedded in the housing 11 is configured as the upper surface of the mounting seat 12. The upper surface of the mounting seat 12 is provided with a mounting groove 121. The atomization module 13 includes a central tube 131 and a heating component 132 arranged in the central tube 131. One end of the central tube 131 is fixed at the mounting groove 121 of the mounting seat 12, and the other end of the central tube 131 is connected to the suction part 111. The sealing silicone 18, the mounting seat 12, the housing 11 and the atomization module 13 define an oil storage cavity, and the oil storage cavity stores the atomization matrix.

[0036] like Figure 2As shown, the electronic atomizer 100 includes an air inlet channel 14 and an air flow sensing channel 15. The mounting base 12 is provided with an air inlet channel 14 from the mounting groove 121 to the surrounding side of the mounting groove 121, and the sealing silicone 18 is provided with an air inlet hole (not shown) connected to the air inlet channel 14. The air flow sensing channel 15 extends from the mounting base 12 to the direction of the main control unit 3. One end of the air flow sensing channel 15 is connected to the air inlet channel 14, and an air flow sensor 31 is fixed to the other end of the air flow sensing channel 15. It can be understood that the air flow sensing channel 15 is a branch of the air inlet channel 14, which is distributed on the side of the air inlet channel 14, and the air flow sensor 31 is arranged at one end of the air flow sensing channel 15 away from the air inlet channel 14. This can reduce the possibility of condensate corroding the air flow sensor 31 during the suction process, increase the service life of the air flow sensor 31 and the electronic atomizer 100, and enhance the user experience. During the specific inhalation process, the user inhales through the suction part 111, so that the central tube 131 generates negative pressure; the external air flows into the mounting base 12, and is automatically divided into two airflows in the mounting base 12, one of which flows into the airflow sensing channel 15 to start the airflow sensor 31 to trigger the start signal, and then flows back to the air intake channel 14; the other airflow flows into the central tube 131 and mixes with the atomized smoke, and brings the atomized smoke out of the atomization module 13 for the user to inhale. In order to further reduce the risk of condensate flowing back to the airflow sensor 31, at least part of the air path structure of the airflow sensing channel 15 or the intersection of the air intake channel 14 and the airflow sensing channel 15 has a bend or the intersection of the air intake channel 14 and the airflow sensing channel 15 is provided with a breathable oil-isolating structure that blocks the flow of condensate.

[0037] In one embodiment, see Figure 3 and Figure 4, an air inlet groove 141 is provided on one side of the mounting seat 12, and a curved groove 142 is provided on the mounting seat 12 from one side of the mounting groove 121 to the direction of the air inlet groove 141. The air inlet groove 141 and the curved groove 142 define an air inlet channel 14, and the air flow sensing channel 15 is located on one side of the curved groove 142 and is connected to the curved groove 142. Among them, the mounting seat 12 is provided with a guide block 123 at the connection between the curved groove 142 and the air flow sensing channel 15. The guide block 123 is similar to a baffle, which can gather most of the gas passing through the air inlet groove 141 to the central tube 131 of the atomization module 13. Of course, there is a gap between the guide block 123 and the air inlet channel 14, so that part of the gas can flow into the air guide channel. Due to the small gap, the condensate flowing out of the atomization module 13 is difficult to flow into the air flow sensor 31 through the gap, so as to prevent the condensate from entering the air flow sensor 31 and prevent the function of the air flow sensor 31 from being affected. Of course, a plurality of oil-absorbing cottons 19 can be provided at the connection between the air inlet channel 14 and the airflow sensing channel 15. Specifically, the oil-absorbing cotton 19 is provided with one side of the guide block 123. The oil-absorbing cotton 19 has good oil absorption and oil locking capabilities and can quickly absorb the outflowing condensate.

[0038] In one embodiment, Figure 4 As shown, the mounting seat 12 is provided with a groove 16 on one side of the air inlet channel 14, the mounting seat 12 is located at the bottom of the groove 16 and a first air guide channel 151 extends toward the lower surface of the mounting seat 12, and the main control unit 3 is provided with a second air guide channel 152 at one end close to the atomizer 1, and the first air guide channel 151 and the second air guide channel 152 form an air flow sensing channel 15, and the air flow sensor 31 is installed in the second air guide channel 152, and one side of the groove 16 is connected to the middle of the air inlet channel 14. In this way, the air flow sensor 31 is arranged in the main control unit 3, and the upper surface of the mounting seat 12 is provided with a groove 16 on one side of the air inlet channel 14, and one side of the groove 16 is connected to the air inlet channel 14, so as to enclose and form an air guide cavity, and the air flow sensing channel 15 extends from the bottom of the air guide cavity toward the main control unit 3 and is arranged in a straight cylindrical shape, and the gas can flow freely in the air guide cavity, and the air flow sensor 31 can sensitively detect the change of air pressure in the airway.

[0039] More specifically, an air guide column 17 protrudes from the bottom of the groove 16, and the first air guide channel 151 passes through the top of the air guide column 17 to the lower surface of the mounting base 12, that is, the first air guide channel 151 is arranged higher than the end surface of the groove 1, and the groove 16 can form a liquid storage tank, which can store condensed liquid flowing out of the atomization module 13, thereby reducing the risk of condensed liquid sliding onto the airflow sensor 31.

[0040] In another embodiment, see Figure 5-Figure 8, the airflow sensing channel 15 includes a first air guide channel 151 and a second air guide channel 152. The first air guide channel 151 extends from the bottom of the mounting groove 121 corresponding to the mounting seat 12 along the height direction of the mounting seat 12 to the middle of the mounting seat 12, and the second air guide channel 152 extends from the middle of the mounting seat 12 toward one side of the mounting seat 12. The airflow sensor 31 is fixed to one end of the second air guide channel 152 away from the first air guide channel 151. Figure 5 As shown, the first air guiding channel 151 is vertically distributed in the middle of the mounting base 12, and the second air guiding channel 152 is horizontally distributed on the mounting base 12. The free end of the second air guiding channel 152 passes through the side wall of the mounting base 12 and extends into the main control unit 3. The second air guiding channel 152 and the first air guiding channel 151 are perpendicular to each other. The condensate sliding down from the central tube 131 is difficult to flow into the second air guiding channel 152, thereby reducing the influence of the condensate on the airflow sensor 31.

[0041] In one embodiment, Figure 2 As shown, the mounting seat 12 has a lead groove 122 extending downward from the bottom of the mounting groove 121, and the lead groove 122 is for the conductive member 133 of the atomizing module 13 to pass through. The end of the mounting seat 12 located at the lead groove 122 is formed with a retaining groove 124 toward the outer peripheral side of the mounting seat 12, and a first conductive part (not shown) is provided in the retaining groove 124, and the main control unit 3 is correspondingly provided with a second conductive part 32 adapted to the first conductive part. In this way, the conductive member 133 in the atomizing module 13 does not need to be treated in any special way, and is directly extended through the lead groove 122 to connect with the first conductive member 133, which is quick and easy to assemble and saves installation space, and effectively eliminates the winding problem.

[0042] In a possible embodiment, please also refer to Figure 1 and Figure 2 The electronic atomizer 100 includes a shell 4 and an oil bottle 2. The upper part of the shell 4 is provided with a receiving groove, and the lower part of the shell 4 is provided with a first receiving cavity (not shown) and a second receiving cavity (not shown) side by side. The main control unit 3 and the oil bottle 2 are fixed in the first receiving cavity and the second receiving cavity respectively. The atomizer 1 is installed in the receiving groove, and the mounting seat 12 is provided with an oil inlet channel 125 connecting the oil bottle 2 and the atomizer 1. Here, the oil bottle 2 is added to the electronic atomizer 100. A large amount of smoke oil can be stored in the oil bottle 2, and the atomizer 1 can be replenished in time to meet the user's demand for large capacity. In addition, the electronic atomizer 100 is modularly arranged according to the function, and each functional module is independent of each other. The oil bottle 2 and the main control unit 3 are not blocked, and can be quickly disassembled and assembled to achieve classified recycling to meet environmental protection requirements.

[0043] More specifically, a plurality of vents 41 are provided on one side of the housing 4, the mounting base 12 is provided with an air inlet channel 14, the two ends of the air inlet channel 14 are respectively connected to the vents 41 and the atomization module 13, and an air regulating valve 42 is slidably mounted on the housing 4 at the vents 41. The air regulating valve 42 controls the air intake volume by controlling the shielding area of ​​the vents 41, thereby achieving the purpose of controlling the amount of smoke.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
