[0031] Please refer to Figure 1 The embodiment of the present application provides an atomization device, which comprises a battery rod 10 and an atomizer 40.

[0032] The battery rod 10 comprises a first shell 11 and a pneumatic switch 13 arranged in the first shell 11, one end of the first shell 11 is provided with a receiving opening 111, and a communication member 12 is arranged in the receiving opening 111, the communication member 12 is internally provided with a communication air channel 121 which is in communication with a cavity 14 where the pneumatic switch 13 is arranged, and a communication hole 122 is arranged in the side wall of the communication member 12 and is in communication with the communication air channel 121; that is, one end of the communication air channel 121 is in communication with the cavity 14, and the other end is in communication with the communication hole 122. The pneumatic switch 13 in the embodiment can be an airflow sensor switch (microphone) or a gas pressure sensor switch.

[0033] The receiving opening 111 of the battery rod 10 is further provided with a sealing member 20 and an elastic member 30, the sealing member 20 is slidably arranged between an open position and a closed position to open or close the communication hole 122; the elastic member 30 is used to provide an elastic force for the sealing member 20 to slide from the open position to the closed position; that is, when the sealing member 20 is not subjected to external force, the elastic member 30 pushes the sealing member 20 to the closed position, thereby sealingly closing the communication hole 122.

[0034] One end of the atomizer 40 is detachably connected with the battery rod 10 through the receiving opening 111, when the atomizer 40 is loaded into the receiving opening 111, the atomizer 40 drives the sealing member 20 to slide from the closed position to the open position against the elastic force of the elastic member 30 to open the communication hole 122 on the communication member, so that the airflow can enter the atomizer 40 through the battery rod 10 when being sucked, and the pneumatic switch 13 in the battery rod 10 can be normally started due to sensing the airflow or gas pressure.

[0035] Specifically, the atomizer 40 comprises a second shell 41 and an atomizing core 42 arranged in the second shell 41, the second shell 41 is internally provided with an atomizing channel 43 which penetrates through the atomizing core 42, one end of the second shell 41 is formed with a suction nozzle 44 which is in communication with the atomizing channel 43, and the other end is provided with a receiving through hole 45 which is in communication with the atomizing channel 43; when the atomizer 40 is loaded into the receiving opening 111, the atomizer 40 drives the sealing member 20 to slide from the closed position to the open position against the elastic force of the elastic member 30, and the communication member 12 extends into the receiving through hole 45, so that the cavity 14 where the pneumatic switch 13 is arranged is in communication with the atomizing channel 43.

[0036] In actual application, the atomizer 40 is in an initial state, and the battery rod 10 and the atomizer 40 are in a separated state, at this time, the sealing member 20 in the battery rod 10 is in the closed position under the elastic force of the elastic member 30, thereby sealingly closing the communication hole 122, so that the cavity 14 where the pneumatic switch 13 is arranged is isolated from the receiving opening 111, thus the battery rod 10 can avoid impurities, water vapor and the like from entering the inside of the cavity 14 to cause damage to the pneumatic switch 13 during assembly, transportation and storage.

[0037] When the atomizer 40 is assembled in the receiving opening 111 of the battery rod 10 to form a complete atomization device, the atomizer 40 pushes the sealing piece 20 to slide from the closed position to the open position, and the communication piece 12 extends into the receiving through hole 45, so that the communication hole 122 on the communication piece 12 is exposed in the receiving through hole 45, so that the chamber 14 is in communication with the atomization channel 43, and the pneumatic switch 13 can normally work when the user performs a suction action.

[0038] When the atomizer 40 is removed from the receiving opening 111 of the battery rod 10, the sealing piece 20 is reset from the open position to the closed position under the elastic force of the elastic piece 30 to seal the communication hole 122, so that the chamber 14 where the pneumatic switch 13 is located is isolated from the receiving opening 111, so that the receiving opening 111 of the battery rod 10 can be washed with water, avoiding the cleaning water from entering the chamber 14 to contact the pneumatic switch 13, and ensuring the safety of the pneumatic switch 13.

[0039] In one embodiment, in combination with Figure 2 As shown, the battery rod 10 further includes a power supply 15, a main control board 16 and a mounting bracket 17, the power supply 15, the main control board 16 and the pneumatic switch 13 are fixedly arranged inside the first shell 11 through the mounting bracket 17, the main control board 16 is electrically connected with the power supply 15 and the pneumatic switch 13 respectively, and the atomization core 42 is electrically connected with the main control board 16 when the atomizer 40 is installed with the battery rod 10. It should be noted that an oil storage cavity is formed between the second shell 41 of the atomizer 40 and the atomization core 42, and atomization liquid is stored in the oil storage cavity. The atomization liquid can penetrate into the atomization core 42 and contact the heating body in the atomization core 42. When the user sucks through the suction nozzle 44, since the atomization channel 43 and the chamber 14 where the pneumatic switch 13 is located are in communication, the pneumatic switch 13 can generate a trigger signal to the main control board 16 according to the change of the air pressure or airflow in the chamber 14, and the heating body in the atomization core 42 is controlled by the main control board 16 to be powered and heated, so as to heat and atomize the atomization liquid in contact with the heating body.

[0040] Specifically, the mounting bracket 17 comprises a mounting plate 171, the mounting plate 171 forms the receiving opening 111 together with the first shell 11, and the communication member 12 and the elastic member 30 are mounted on the mounting plate 171. The mounting bracket 17 is integrally made of insulating material, and the mounting plate 171 separates the inside of the first shell 11 and the receiving opening 111, and only the communication air channel 121 in the inside of the communication member 12 penetrates through the communication receiving opening 111 and the chamber 14 in the inside of the first shell 11; thus, when the atomizer 40 is removed from the receiving opening 111, after the sealing member 20 slides to the closed position to close the communication hole 122, the inside of the first shell 11 and the receiving opening 111 can be completely isolated, so that the area of the receiving opening 111 can be washed with water, and the situation that too much atomized liquid and dust and other substances accumulated in the receiving opening 111 cause short circuit can be avoided.

[0041] In combination with Figure 5 As shown in the figure, two spring needle connectors 18 are further arranged on the mounting plate 171, and the other end (lower end) of the second shell 41 is provided with two conductive electrodes 46 electrically connected with the atomizing core 42; when the atomizer 40 is mounted in the receiving opening 111, the atomizing core 42 is electrically connected with the main control board 16 through the abutment of the two conductive electrodes 46 and the two spring needle connectors 18.

[0042] In the embodiment, the atomizer 40 and the battery rod 10 are connected in the direction of the central axis by plug-in connection, mainly to make the lower end of the atomizer 40 in interference fit with the receiving opening 111 of the battery rod 10, so as to realize the detachable connection of the atomizer 40 and the battery rod 10; of course, in other embodiments, other ways such as buckle connection, magnetic attraction connection and the like can also be used to realize the detachable connection of the atomizer 40 and the battery rod 10.

[0043] In one embodiment, in combination with Figure 4 As shown in the figure, the communication member 12 comprises a main body and a stop portion 123 radially protruding from the top end of the main body, and the communication hole 122 is arranged on the side wall of the main body adjacent to the stop portion 123 and is higher than the upper surface of the mounting plate 171; the sealing member 20 and the elastic member 30 are sleeved on the main body, and one end of the elastic member 30 abuts against the mounting plate 171 and the other end abuts against the sealing member 20, so that the sealing member 20 elastically abuts against the stop portion 123. The outer diameter of the sealing member 20 is greater than the outer diameter of the stop portion 123, so that when the atomizer 40 is inserted into the receiving opening 111, the sealing member 20 can be pushed to move downward, so that the communication hole 122 on the side wall of the main body is exposed to the receiving through hole 45, and the communication of the atomizing channel 43 and the chamber 14 is realized.

[0044] Specifically, the hole diameter of the receiving through hole 45 is greater than the outer diameter of the connecting member 12 and less than the outer diameter of the sealing member 20, that is, the hole diameter of the receiving through hole 45 is greater than the outer diameter of the stop portion 123. In this way, when the atomizer 40 is inserted into the receiving opening 111, the connecting member 12 can enter the receiving through hole 45, and the lower end of the receiving through hole 45 is used to abut against the upper end of the sealing member 20 to drive the sealing member 20 to slide downward, so that the connecting hole 122 is exposed.

[0045] Further, in order to make the structure more compact and reasonable, and to better push the sealing member 20 to slide, the receiving through hole 45 in the embodiment is provided with a second stepped hole 451 at one end away from the suction nozzle 44, and the hole diameter of the second stepped hole 451 is greater than the outer diameter of the sealing member 20. In this way, when the atomizer 40 is inserted into the receiving opening 111, the upper end of the sealing member 20 is accommodated in the second stepped hole 451.

[0046] In one embodiment, the battery rod 10 further comprises a sealing cover 19, the sealing cover 19 is fixedly arranged on one side of the main control plate 16 and forms a chamber 14 with the main control plate 16, the pneumatic switch 13 is fixed on the main control plate 16 and located in the chamber 14, the lower end of the main body is fixed through the installation horizontal plate 171 and connected with the sealing cover 19, and the chamber 14 is communicated. That is to say, the upper end of the main body protrudes from the upper surface of the installation horizontal plate 171 and is sleeved with the sealing member 20 and the elastic member 30, the lower end of the main body protrudes from the lower surface of the installation horizontal plate 171 and is fixedly connected with the sealing cover 19, so that the connecting air channel 121 in the main body is communicated with the chamber 14.

[0047] In the embodiment, as shown in Figure 2 , the elastic member 30 is a compression spring, the sealing member 20 is formed with a first stepped hole 21 at one end away from the stop portion 123, and at least a part of the elastic member 30 is accommodated in the first stepped hole 21. In the embodiment, the compression spring is used to provide the sealing member 20 with the force for abutting against the stop portion 123 by using the elastic force of the compression spring itself. Of course, in other embodiments, as shown in Figure 6 , the sealing member 20 and the elastic member 30 can also be an integrally formed structure, which is made of a flexible gel material, and the wall thickness of the elastic member 30 is less than that of the sealing member 20. When the atomizer 40 is inserted into the receiving opening 111, the sealing member 20 is pushed to move downward to the open position, and because the wall thickness of the elastic member 30 is thin, the elastic member 30 is in a compressed state. When the atomizer 40 is pulled out of the receiving opening 111, the elastic member 30 is restored to the original state from the compressed state, so as to push the sealing member 20 to move upward to the closed position.

[0048] In one embodiment, in combination with Figure 3 and Figure 5As shown, the receiving holes 45 in the atomizer 40 are at least two, and in the embodiment, two receiving holes 45 are exemplified, which are symmetric to the central axis of the atomizer 40. In actual use, the side wall of the first shell 11 and / or the second shell 41 is further provided with an air inlet hole 47. When the atomizer 40 is installed with the battery rod 10, one of the receiving holes 45 is used to receive the connecting piece 12 to make the atomization channel 43 communicate with the chamber 14, and the air outside the atomization device can enter the atomization channel 43 through the air inlet hole 47, and after mixing with the aerosol generated in the atomization core 42, it is sucked out from the suction nozzle 44 by the user. The symmetric arrangement of the two receiving holes 45 makes the insertion of the atomizer 40 and the battery rod 10 more convenient.

[0049] As shown above, by arranging the connecting piece 12 with the communication hole 122, the sealing piece 20 and the elastic piece 30 in the receiving opening 111, when the atomizer 40 is installed in the receiving opening 111 of the battery rod 10, the sealing piece 20 can be pushed to move to the open position to expose the communication hole 122, so that the atomization channel 43 in the atomizer 40 communicates with the chamber 14 in the battery rod 10, and the normal use of the pneumatic switch 13 is realized; when the atomizer 40 is taken out from the receiving opening 111 of the battery rod 10, the sealing piece 20 can move to the closed position under the action of the elastic piece 30 to seal the communication hole 122, so that the receiving opening 111 can be washed, without worrying about the cleaning water entering the chamber 14 to contact the pneumatic switch 13, so as to ensure the safety of the pneumatic switch 13.

[0050] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0051] The above is the description of the technical solutions provided by the present application.
