For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0035] In the related art, in order to ensure the integrity of the internal structure and avoid the leakage of aerosol substrate during transportation, the existing atomizer usually adopts the method of using a silica gel plug to block the air inlet 202 and the air outlet 203 of the atomizer. However, this method actually faces a series of challenges, especially when it comes to disposable atomizers. Due to the structural characteristics of disposable atomizers, the airway design is often complex and delicate, which makes it difficult to achieve complete sealing of the upper and lower ends of the airway during blocking. It should be noted that the atomizing device provided in the present application can be a disposable atomizing device or a replaceable atomizing device.

[0036] The embodiment of the present application provides an atomizing device, relating to the technical field of electronic atomization, which is mainly used for atomizing aerosol substrate to form aerosol for user use.

[0037] In combination with FIGS. 1-3, Figure 2 Figure 3 As shown in the drawings, the atomizing device provided by the embodiment includes a shell 100, an atomizing assembly 200, a first sealing member 110, and a power supply assembly 300.

[0038] The atomizing assembly 200 is arranged in the shell 100, and the atomizing assembly 200 has an atomizing channel 201; the atomizing channel 201 has an air inlet 202 and an air outlet 203; the first sealing member 110 is located at the lower part of the air inlet 202 and is used for blocking the air inlet 202; in an embodiment, the air outlet 203 is also blocked by a second sealing member 120; the power supply assembly 300 is arranged in the shell 100 and located at the side of the atomizing assembly 200 close to the air inlet 202, and the power supply assembly 300 includes a breather pipe 310; the atomizing assembly 200 can move relative to the shell 100 towards the direction close to the breather pipe 310, so that the breather pipe 310 pierces the first sealing member 110, and the breather pipe 310 and the atomizing channel 201 are in communication.

[0039] ​The atomization device provided by the embodiment achieves effective isolation between the atomization assembly 200 and the power supply assembly 300 by arranging the first sealing member 110 at the air inlet 202 and the second sealing member 120 at the air outlet 203, and finally completely isolates the inside of the atomization assembly 200 from the outside. The main purpose of this design is to ensure that the aerosol substrate in the atomization assembly 200 does not leak due to external factors such as vibration or improper handling during transportation or storage of the atomization device. In this way, not only is the waste of aerosol substrate avoided, but more importantly, damage to the power supply assembly 300 and the like inside the atomization device caused by leakage is prevented, thereby ensuring the overall performance and service life of the atomization device.

[0040] When the user actually uses the atomization device, the operation process is also designed to be very simple. The user only needs to simply move the atomization assembly 200 relative to the shell 100 towards the direction of approaching the air tube 310. This action will cause the air tube 310 to come into contact with and pierce the first sealing member 110. Once the first sealing member 110 is pierced, the air tube 310 can smoothly communicate with the atomization channel 201, and the second sealing member 120 at the air outlet 203 is removed. In this way, the user can suck the atomization assembly 200 from the air outlet 203, and the air tube 310 can start to supply air to the atomization channel 201, so that the user can normally use the atomization device for atomization operation.

[0041] In some embodiments, the side wall of the air tube 310 is provided with a first air passage hole 311, and the power supply assembly 300 is further provided with an air inlet channel. The air inlet channel is in air communication with the first air passage hole 311, and the air tube 310 and the air inlet channel are arranged in different axes in the length direction of the atomization device. Through the movement of the atomization assembly 200, the atomization channel 201 communicates with the air inlet channel via the inside of the air tube 310 and the first air passage hole 311. Since the air inlet channel and the air tube 310 are arranged in different axes, even if liquid leakage occurs during use of the atomization device, the air inlet channel will not be contaminated. In some embodiments, the side of the air tube 310 close to the power supply assembly 300 can be sealingly arranged, and this side is not in air communication with the air inlet channel, so that even if liquid leaks from the atomization channel 201, it will not leak to the power supply assembly 300 when the air tube 310 and the atomization channel 201 are coaxially arranged.

[0042] In the case of a disposable atomization device, in one embodiment, at least a portion of the air tube 310 is pre-inserted into the inside of the atomization assembly 200, so that when the atomization assembly 200 is moved, the air tube 310 itself can serve as a guide, making the movement of the atomization assembly 200 smoother. In the case of a replaceable atomization assembly 200, the side of the atomization assembly 200 can be provided with a guide slider, and the inside of the shell 100 is provided with a corresponding guide sliding groove, so that when the atomization assembly 200 moves relative to the shell 100, the bottom of the atomization assembly 200 is aligned with the air tube 310.

[0043] In one embodiment, the power supply assembly 300 includes a power supply 320 and an induction bracket 330, which is arranged at the end of the power supply 320 close to the atomization assembly 200. The induction bracket 330 is provided with an airflow sensor 331, and one end of the air tube 310 is inserted into the induction bracket 330, so that the one end of the air tube 310 is sealingly fixed to the induction bracket 330. When a user inhales from the air outlet 203 of the present embodiment, airflow is quickly generated at the air tube 310, which is sensed by the airflow sensor 331, triggering the atomization assembly 200 to work, making the atomization assembly 200 fast and sensitive. The power supply 320 has an electrode column 321, and the atomization assembly 200 is close to the power supply assembly 300, which can drive the electrode column 321 to penetrate into the atomization assembly 200 and electrically connect with the electrode contact of the heating element 260, so that the atomization assembly 200 and the power supply assembly 300 are in a disconnected state during transportation of the present embodiment, effectively avoiding accidental activation of the atomization assembly 200 and ensuring the safety of the present embodiment. When a user uses the present embodiment, the electrode column 321 penetrates into the atomization assembly 200 and electrically connects with the electrode contact of the heating element 260 while the air tube 310 pierces the first sealing member 110, so that the atomization assembly 200 is powered on, which is convenient and fast.

[0044] In some embodiments, the atomization assembly 200 includes a liquid storage cup 210, an atomization bracket 220, and a base 230. The atomization bracket 220 is arranged in the liquid storage cup 210, and the liquid storage cup 210 and the atomization bracket 220 form a liquid storage cavity 211. In one embodiment, the base 230 is provided with a perforation 231, and the air tube 310 is pre-inserted through the perforation 231, facilitating the passage of the air tube 310.

[0045] In an embodiment, the upper portion of the induction bracket 330 is provided with an induction airway, which is in airway communication with the first air passing hole 311. The induction airway, the air vent tube 310 and the air inlet are arranged in different axes two by two. The three are communicated with the first air passing hole 311, so that after the air vent tube 310 pierces the first sealing member 110, the induction airway and the air inlet of the atomization device are activated.

[0046] In some embodiments, the first sealing member 110 is arranged between the atomization bracket 220 and the base 230, and the base 230 is arranged in the liquid storage cup 210 and pushes the first sealing member 110, so that the first sealing member 110 is tightly matched with the atomization bracket 220, thereby enabling the first sealing member 110 to reliably seal the air inlet 202 and ensuring the sealing effect of the first sealing member 110 on the air inlet 202.

[0047] In some embodiments, a sealing ring 212 is arranged between the outer side wall of the base 230 and the inner side wall of the liquid storage cup 210, so as to ensure the sealing cooperation between the base 230 and the inner side wall of the liquid storage cup 210 and avoid liquid leakage.

[0048] In some embodiments, the end portion of the atomization bracket 220 near the air inlet 202 is provided with a matching step 221, the end face of the first sealing member 110 near the atomization bracket 220 is provided with a sleeve 111, the sleeve 111 is sleeved outside the matching step 221, the end face of the base 230 near the atomization bracket 220 is provided with a matching groove 232, the matching groove 232 is sleeved outside the sleeve 111, the outer side wall of the sleeve 111 is provided with a sealing convex ring 112, and the perforation 231 is located at the groove bottom of the matching groove 232. Through the cooperation of the sleeve 111 and the matching step 221, the contact area of the first sealing member 110 and the atomization bracket 220 is improved, the cooperation reliability is improved, and assembly is facilitated. Through the close cooperation of the sealing convex ring 112 and the inner side wall of the matching groove 232, the close cooperation of the first sealing member 110 and the matching groove 232 is improved, so as to drive the close cooperation of the sleeve 111 and the matching step 221, and finally improve the sealing performance of the air inlet 202.

[0049] In some embodiments, the groove bottom of the matching groove 232 is provided with a liquid suction groove 233, the liquid suction groove 233 is provided with a liquid suction member 234, and the perforation 231 is arranged at the groove bottom of the liquid suction groove 233. The condensate generated by the user during use of the embodiment can be adsorbed and gathered, the probability of the condensate flowing out of the air outlet 203 is reduced, and the user experience is ensured.

[0050] In some embodiments, the atomization assembly 200 further comprises an atomization tube 240, a liquid guide 250, and a heating member 260. The liquid guide 250 is arranged in the atomization tube 240 and used to guide the aerosol substrate in the liquid storage cavity 211 into the atomization tube 240. The heating member 260 is arranged in the liquid guide 250 and used to atomize the aerosol substrate in the atomization tube 240. The liquid storage cup 210 is provided with an air passage 213, which is in communication with the atomization tube 240 to form an atomization channel 201, so as to mix and atomize the aerosol substrate and the airflow to generate an aerosol.

[0051] In some embodiments, the induction bracket 330 is provided with an air passage gap 332. The power supply member 320 comprises a power supply bracket 322, a power supply 323, and a circuit board 324. The power supply 323 and the circuit board 324 are arranged on the power supply bracket 322. The electrode column 321 is arranged on the circuit board 324. The circuit board 324 is provided with a second air passage hole 3241, which is used to ensure the installation reliability of each electrical component. The bottom of the shell 100 is provided with an air inlet hole. The second air passage hole 3241, the air inlet hole, the air passage gap 332, and the power supply bracket 322 jointly form an air inlet channel with the shell 100, which is used to reverse the airflow entering from the air inlet 202.

[0052] In some embodiments, the end of the shell 100 away from the atomization assembly 200 is provided with a bottom cover 130. The bottom cover 130 is provided with an air permeable hole 131 for the airflow to enter. The circuit board 324 is provided with an indicator light. The shell 100 is further provided with a light guide member 325. One side of the light guide member 325 is arranged close to the indicator light. The other end of the light guide member 325 extends to the air permeable hole 131. The light guide member 325 can guide the light emitted by the indicator light and emit the light from the air permeable hole 131. The user can determine the working state of the present embodiment according to the brightness of the indicator light, which ensures the user experience.

[0053] As Figure 1As shown, in some embodiments, the outer circumferential surface of the atomization assembly 200 is provided with a spacer 140 between one end of the shell 100 and the atomization assembly 200, which prevents the atomization assembly 200 from moving towards the power supply assembly 300. The spacer 140 is in particular a strip, which is arranged on the outside of the liquid storage cup 210 of the atomization assembly 200, between the end of the shell 100 close to the air outlet 203 and the liquid storage cup 210, to prevent the atomization assembly 200 from moving towards the power supply assembly 300. This avoids the relative movement between the atomization assembly 200 and the shell 100 during transportation due to external force, which causes the air tube 310 to pierce the first sealing member 110 and cause leakage of the aerosol substrate, thereby improving the reliability of the embodiment during transportation. When the user uses the embodiment, the spacer 140 can be removed or torn from the liquid storage cup 210 to remove the obstacle to the relative movement between the atomization assembly 200 and the shell 100, so that the user can use it normally, which is simple and fast.

[0054] As shown in the drawings, Figure 4 In some embodiments, the end of the air tube 310 close to the first sealing member 110 is provided with a piercing tip, which facilitates the quick piercing of the first sealing member 110 by the air tube 310.
