Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to atomizers and atomizing devices. Background Technology

[0002] Atomizers typically contain an atomizing core and a reservoir to store the atomizing matrix. The atomizing core can use the atomizing matrix in the reservoir to perform atomization operations. However, if the atomizing core and the atomizing matrix in the reservoir remain in contact even when not in use, problems such as oil leakage may occur, affecting the user experience of the atomizer. Summary of the Invention

[0003] In view of the above problems, an atomizer and atomizing device are proposed to overcome or at least partially solve the above problems, including:

[0004] An atomizer, comprising:

[0005] The housing assembly has a liquid storage chamber inside, which is used to store the atomizing matrix;

[0006] The atomizing component is disposed in the liquid storage chamber. The atomizing component includes an atomizing seat and an atomizing core. The atomizing seat has a communicating atomizing channel and a liquid inlet. The atomizing core is located in the atomizing channel and covers the liquid inlet.

[0007] A bottom cover assembly, movably connected to one end of a housing assembly, the bottom cover assembly being movable relative to the housing assembly and having a first position and a second position; and

[0008] When the bottom cover assembly is in the first position, there is a gap between the bottom cover assembly and the atomizing seat, and the liquid inlet is blocked by the housing assembly to prevent the liquid storage chamber from communicating with the atomizing channel; when the bottom cover assembly is switched to the second position, the bottom cover assembly pushes the atomizing seat to move relative to the housing assembly, so that the liquid inlet and the liquid storage chamber are connected to each other, thereby connecting the liquid storage chamber and the atomizing channel.

[0009] In some embodiments, the atomizing seat includes a sidewall portion and a base portion, an atomizing channel is formed inside the sidewall portion, a liquid inlet is disposed on the periphery of the sidewall portion, and the base portion is disposed on the side of the sidewall portion near the bottom cover assembly.

[0010] The bottom cover assembly includes a pusher portion, which is disposed opposite to the base portion;

[0011] When the bottom cover assembly is in the first position, the pushing part and the base part are spaced apart; when the bottom cover assembly is switched to the second position, the pushing part abuts against the base part to push the atomizing seat to move relative to the housing assembly.

[0012] In some embodiments, the base portion protrudes from the outer periphery of the sidewall portion, and a limiting groove is provided on the side of the base portion facing the pushing portion;

[0013] When the bottom cover assembly is in the second position, the pushing part is inserted into the limiting groove, and the pushing part abuts against the groove wall of the limiting groove.

[0014] In some embodiments, the atomizing core has a conductive wire, one end of which extends into a limiting groove, and an electrode assembly is provided on the pushing part.

[0015] The bottom cover assembly moves relative to the housing assembly and has a third position, which is located between the first position and the second position;

[0016] When the bottom cover assembly is in the first position, the conductive wire and the electrode assembly are separated. When the bottom cover assembly switches from the first position to the third position, the electrode assembly is housed in the limiting groove and the electrode assembly contacts the conductive wire to form an electrical connection.

[0017] In some embodiments, the bottom cover assembly includes a bottom shell component, and the housing assembly includes an outer shell component and a seal;

[0018] The outer shell has a first end and a second end, and the outer shell has an air outlet. The air outlet is disposed on the first end of the outer shell. The atomizing seat extends from the first end of the outer shell toward the second end of the outer shell. The end of the atomizing seat away from the base is movably connected to the air outlet. The bottom shell is movably connected to the second end of the outer shell. A sealing element is sealed between the outer shell and the atomizing seat to form a liquid storage cavity between the outer shell, the air outlet, the atomizing seat and the sealing element.

[0019] When the bottom shell moves relative to the outer shell, the pushing part cooperates with the base part to drive the atomizing seat to move relative to the sealing part, so that the sealing part blocks or opens the liquid inlet hole.

[0020] In some embodiments, the bottom shell has a mounting groove on the side facing the atomizing seat. The bottom shell has a peripheral wall and a bottom, which together form the mounting groove. A pushing part protrudes from the bottom into the mounting groove. A positioning part is provided on the side of the peripheral wall facing the outer shell. The outer shell has a first positioning hole and a second positioning hole. The first positioning hole is set at a first position, and the second positioning hole is set at a second position. The positioning part is snapped into the first positioning hole or the second positioning hole.

[0021] In some embodiments, the bottom shell is provided with a guide post, which is embedded in the bottom of the mounting groove. The guide post and the positioning part are integrally formed. The sealing part has a guide hole, and the guide post is slidably inserted into the guide hole.

[0022] And / or, the outer peripheral side of the peripheral wall is provided with a guide portion protruding outward, and the outer casing is provided with a guide groove on the side facing the peripheral wall, and the guide portion is slidably connected in the guide groove.

[0023] In some embodiments, the bottom shell is also provided with an air intake channel, and the side wall is provided with an air intake hole. The air intake channel, the air intake hole, the atomizing channel, and the air outlet are connected in sequence.

[0024] The outer surface of the side wall is also provided with a ventilation groove. The ventilation groove is located in the area between the liquid inlet and the base. One end of the ventilation groove is connected to the liquid inlet, and the other end of the ventilation groove bends and extends from the liquid inlet toward the base.

[0025] When the bottom shell is in the second position, one end of the air exchange groove is connected to the liquid storage chamber through the liquid inlet hole, and the other end of the air exchange groove is connected to the air inlet channel.

[0026] In some embodiments, the bottom cover assembly includes a bottom shell member, and the housing assembly includes an outer shell member, with the bottom shell member mounted at one end of the outer shell member;

[0027] The atomizer also includes a circuit board and an airflow sensor. The airflow sensor is mounted on the circuit board. A mounting structure is formed on the side of the bottom shell facing away from the outer shell. The circuit board and the airflow sensor are mounted on the mounting structure. The electrode assembly passes through the bottom shell and is electrically connected to the circuit board. A detection air passage is formed on the side of the bottom shell facing the outer shell. The atomization channel is connected to the airflow sensor through the detection air passage.

[0028] An atomizing device includes a power supply component and an atomizer as described above, wherein the atomizer is disposed on the power supply component and electrically connected to the power supply component.

[0029] The embodiments of this application have the following advantages:

[0030] In this embodiment, the atomizer includes a housing assembly, an atomizing assembly, and a bottom cover assembly. The housing assembly has a liquid storage chamber inside for storing the atomizing matrix. The atomizing assembly is disposed within the liquid storage chamber and includes an atomizing seat and an atomizing core. The atomizing seat has a communicating atomizing channel and a liquid inlet. The atomizing core is located within the atomizing channel and covers the liquid inlet. The bottom cover assembly is movably connected to one end of the housing assembly. The bottom cover assembly moves relative to the housing assembly and has a first position and a second position. When the bottom cover assembly is in the first position, there is a gap between the bottom cover assembly and the atomizing seat, and the liquid inlet is blocked by the housing assembly to prevent communication between the liquid storage chamber and the atomizing seat. The atomization channel is connected; the bottom cover assembly switches to the second position, and the bottom cover assembly pushes the atomizer base to move relative to the housing assembly, so that the liquid inlet and the liquid storage chamber are connected, thus connecting the liquid storage chamber and the atomization channel. This setting not only realizes the separation of the atomization matrix and the atomizer core in the liquid storage chamber when not in use, reducing the possibility of oil leakage, but also ensures that when the atomizer is not activated, that is, when the bottom cover assembly is in the first position and a safe distance is maintained between the bottom cover assembly and the atomizer base, the atomizer will not be easily activated even if the bottom cover assembly is subjected to a violent impact during transportation, thereby further preventing oil leakage and greatly improving the user experience.

[0054] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 The diagram shows a schematic of an atomizing device provided in some embodiments of this application. The atomizing device includes an atomizer 1 and a power supply component 2. The atomizer 1 is disposed on the power supply component 2 and is electrically connected to the power supply component 2. The power supply component 2 supplies power to the atomizer 1, enabling the atomizer 1 to perform atomization operations.

[0055] In some examples, the power supply component 2 may include a housing 21 and a battery 24, with the battery 24 and the atomizer 1 installed in the cavity formed by the housing 21, and the power supply component 2 may power the atomizer 1 through the battery 24.

[0056] In some examples, a switch button 22 is provided on the side of the housing 21 of the power supply component 2 facing out of the cavity, and the user can control the power supply to be turned on or off by operating the switch button 22.

[0057] In some examples, the power supply component 2 may also include a bottom cover 23, which may be located on the side away from the atomizer 1 and is movably connected to the housing 21.

[0058] The following combination Figures 2 to 11 Further explanation of the atomizer 1 in some embodiments of this application:

[0059] The atomizer 1 may include a housing assembly 10, an atomizing assembly 20, and a bottom cover assembly 30.

[0060] like Figure 2 , Figure 3 The housing assembly 10 has a liquid storage chamber 110 inside, which can be used to store the atomizing matrix. The atomizing matrix is ​​in liquid form, such as oil, and can carry different odors. The atomizing matrix can be heated by the atomizing assembly 20 to perform atomization, thereby generating aerosol. The generated aerosol is discharged through the housing assembly 10.

[0061] In some examples, to meet the regulatory requirements of different regions, the content of the atomizing matrix stored in the reservoir 110 can be between 1 and 4 ml, specifically 1 ml, 2 ml, 3 ml, 3.5 ml, and 4 ml, etc., without specific limitations here.

[0062] In some examples, the material of the housing assembly 10 may be selected from any of the following: hard resin, metal and its alloys, glass, ceramics and synthetic materials, without specific limitations.

[0063] like Figure 2 , Figure 3 The atomizing component 20 is disposed in the liquid storage chamber 110. The atomizing component 20 may include an atomizing seat 210 and an atomizing core 220. The atomizing seat 210 has a communicating atomizing channel 211 and a liquid inlet 2121. The atomizing core 220 is located in the atomizing channel 211 and covers the liquid inlet 2121.

[0064] During atomization, the atomization channel 211 and the liquid storage chamber 110 can be connected through the liquid inlet 2121. The atomization matrix in the liquid storage chamber 110 can enter the atomization channel 211 through the liquid inlet 2121. The atomization core 220 in the atomization channel 211 can then perform atomization on the atomization matrix that has entered the atomization channel 211. The aerosol generated during the atomization operation is discharged through the atomization channel 211.

[0065] In some examples, the atomizing core 220 may include a liquid guiding element and a heating grid. The heating grid may be disposed on one side of the liquid guiding element, and the other side of the liquid guiding element covers the liquid inlet hole 2121. The area of ​​the liquid guiding element is larger than the area of ​​the liquid inlet hole 2121. The atomizing matrix enters the liquid guiding element through the liquid inlet hole 2121, and the heating grid atomizes the atomizing matrix in the liquid guiding element to generate an aerosol.

[0066] In some examples, the liquid-guiding component is liquid-guiding cotton, and the material of the liquid-guiding cotton can be selected from any of cotton or non-woven fabric, such as sponge, cotton, rayon, non-woven fabric, etc.

[0067] In some examples, one or more inlet holes 2121 can be provided. By providing multiple inlet holes 2121, the speed at which the atomizing matrix enters the atomizing channel can be increased.

[0068] The bottom cover assembly 30 is movably connected to one end of the housing assembly 10. The bottom cover assembly 30 can move relative to the housing assembly 10. For example, under the action of an external force, the housing assembly 10 can move toward the bottom cover assembly 30. When the bottom cover assembly 30 moves relative to the housing assembly 10, it has a first position and a second position. The second position is a position that is closer to the atomizing component 20 than the first position.

[0069] When the bottom cover assembly 30 is in the first position during non-operational states, such as Figure 4 The bottom cover assembly 30 and the atomizing seat 210 are spaced apart, meaning that the bottom cover assembly 30 and the atomizing seat 210 do not contact each other. The liquid inlet 2121 is blocked by the housing assembly 10 to prevent the liquid storage chamber 110 from communicating with the atomizing channel 211. The atomizing matrix in the liquid storage chamber 110 cannot enter the atomizing channel 211, and the atomizing core 220 cannot perform atomization operations.

[0070] When a user wants to use the atomizer 1 for atomization, the user presses the housing assembly 10 towards the side closest to the bottom cover assembly 30. Since the bottom cover assembly 30 and the housing assembly 10 are connected, during the process of switching the bottom cover assembly 30 to the second position, as... Figure 6 The bottom cover assembly 30 first moves a certain distance to contact the atomizing base 210, causing a portion of the bottom cover assembly 30 to abut against the bottom of the atomizing base 210. Then, the housing assembly 10 is pressed down further, causing the bottom cover assembly 30 to push the atomizing base 210 relative to the housing assembly 10, thus connecting the liquid inlet 2121 with the liquid storage chamber 110, thereby connecting the liquid storage chamber 110 with the atomization channel 211. At this point, the liquid inlet 2121 is no longer blocked by the housing assembly 10, and the liquid storage chamber 110 and the atomization channel 211 are connected through the liquid inlet 2121. The atomizing substrate in the liquid storage chamber 110 enters the atomization channel 211, and the atomizing core 220 then uses the atomizing substrate entering the atomization channel 211 to perform atomization. In other operating methods, the user can also achieve displacement between the bottom cover assembly 30 and the housing assembly 10 by rotating the bottom cover assembly 30, etc., which are not specifically limited here.

[0071] In this embodiment, the bottom cover assembly 30 is movably connected to one end of the housing assembly 10. The bottom cover assembly 30 moves relative to the housing assembly 10 and has a first position and a second position. When the bottom cover assembly 30 is in the first position, there is a gap between the bottom cover assembly 30 and the atomizing seat 210, and the liquid inlet 2121 is blocked by the housing assembly 10 to prevent communication between the liquid storage chamber 110 and the atomizing channel 211. When the bottom cover assembly 30 switches to the second position, the bottom cover assembly 30 pushes the atomizing seat 210 to move relative to the housing assembly 10, so that the liquid inlet 2121 and the liquid storage chamber 110 are connected. 10 is connected to the liquid storage chamber 110 and the atomizing channel 211. This design not only separates the atomizing matrix from the atomizing core 220 in the liquid storage chamber 110 when not in use, reducing the risk of oil leakage, but also ensures that the atomizer 1 is in an inactive state, i.e., the bottom cover assembly 30 is in the first position and a safe distance is maintained between the bottom cover assembly 30 and the atomizing base 210. During transportation, even if the bottom cover assembly 30 is subjected to a violent impact, the atomizer 1 will not be easily activated, thereby further preventing oil leakage and greatly improving the user experience.

[0072] like Figure 7 The atomizing base 210 may include a sidewall portion 212 and a base portion 213. An atomizing channel 211 is formed inside the sidewall portion 212, a liquid inlet 2121 is disposed on the periphery of the sidewall portion 212, and the base portion 213 is disposed on the side of the sidewall portion 212 near the bottom cover assembly 30. For example... Figure 9 The bottom cover assembly 30 may include a pusher portion 311, which is disposed opposite to the base portion 213.

[0073] In the non-operating state, when the bottom cover assembly 30 is in the first position, the pushing part 311 and the base part 213 are spaced apart, that is, the pushing part 311 and the base part 213 are not in direct contact. With the action of external force, the bottom cover assembly 30 moves continuously relative to the housing assembly 10. When the bottom cover assembly 30 switches to the second position, the pushing part 311 abuts against the base part 213 to push the atomizing seat 210 to move relative to the housing assembly 10.

[0074] Since the push part 311 in the bottom cover assembly 30 and the base part 213 in the atomizing seat 210 are arranged opposite to each other, under the action of external force, the bottom cover assembly 30 including the push part 311 and the atomizing seat 210 including the base part 213 move relative to each other. When the push part 311 moves to the second position, the push part 311 abuts against the base part 213. The push part 311 pushes the base part 213, thereby pushing the atomizing seat 210 to move relative to the housing assembly 10 until the liquid inlet 2121 is no longer blocked by the housing assembly 10, the liquid storage chamber 110 is connected to the atomizing channel 211, and the atomizing matrix in the liquid storage chamber 110 enters the atomizing channel 211.

[0075] In some examples, the pusher 311 can be one or more.

[0076] In some examples, a support portion (not shown in the figure) may be provided on the side wall portion 212 of the atomizer seat 20 facing the atomization channel 211, which can be used to support the atomizer core 220 in the atomization channel 211.

[0077] In some examples, the sidewall portion 212 of the atomizing seat 20 forms a cylindrical atomizing channel.

[0078] In some examples, the base portion 213 of the atomizer 20 may be located at the bottommost position 313 of the side wall portion 212 near the bottom cover assembly 30.

[0079] like Figure 10 The base portion 213 protrudes from the outer periphery of the side wall portion 212. A limiting groove 2131 is provided on the side of the base portion 213 facing the pushing portion 311. The shape of the pushing portion 311 can be adapted to the size of the limiting groove 2131. Since the base portion 213 has a limiting groove 2131 on the side facing the pushing portion 311, when the bottom cover assembly 30 is in the second position, the pushing portion 311 is inserted into the limiting groove 2131 and abuts against the groove wall of the limiting groove 2131 to achieve the pushing effect.

[0080] like Figure 5 The atomizing core 220 has a conductive wire 221, one end of which extends into the limiting groove 2131. The pushing part 311 may be provided with an electrode assembly 3111. The bottom cover assembly 30 has a third position relative to the housing assembly 10, and the third position is located between the first position and the second position.

[0081] When the bottom cover assembly 30 is in the first position, such as Figure 4 Since the pushing part 311 and the base part 213 are spaced apart, the electrode assembly 3111 on the pushing part 311 is not inserted into the limiting groove 2131 of the base part 213. The conductive wire 221 and the electrode assembly 3111 are separated, and no current flows to the atomizing core 220. Therefore, the atomizing core 220 cannot perform atomization.

[0082] The bottom cover assembly 30 switches from the first position to the third position, as follows: Figure 5 The electrode assembly 3111 is housed within the limiting groove 2131, and the electrode assembly 3111 contacts the conductive wire 221 to form an electrical connection. The current in the power supply assembly 2 then flows through the electrode assembly 3111 and the conductive wire 221 to the atomizing core 220, which can then perform atomization operations.

[0083] It should be noted that after the bottom cover assembly 30 is switched from the first position to the third position, and then from the third position to the second position, the electrode assembly 3111 is in contact with the conductive wire 221 to form an electrical connection.

[0084] In some examples, the heating mesh in the atomizing core 220 is connected to the conductive wire 221. Under the action of current, the heating mesh heats the atomizing matrix, thereby producing an atomization operation.

[0085] In some examples, the conductive wires 221 in the atomizer core 220 can be one or more.

[0086] In some examples, the electrode assembly 3111 is adapted to the shape of the limiting groove 2131, such as a column.

[0087] In this embodiment, when the bottom cover assembly 30 is in the first position, since the pushing part 311 in the bottom cover assembly 30 and the base part 213 in the atomizing seat 210 are spaced apart, the electrode assembly 3111 on the pushing part 311 is not inserted into the limiting groove 2131 in the base part 213. The conductive wire 221 in the limiting groove 2131 and the electrode assembly 3111 are in a separated state. Under the action of external force, the bottom cover assembly 30 moves relative to the housing assembly 10, and the bottom cover assembly 30 switches from the first position to the third position. The electrode assembly 3111 is housed in the limiting groove 2131, and the electrode assembly 3111 then contacts the conductive wire 221 in the limiting groove 2131 to form an electrical connection. This realizes that the conductive wire 221 in the atomizing core 220 is separated from the electrode assembly 3111 in the non-operating state, thereby avoiding the situation where the atomizing matrix in the liquid storage chamber 110 is separated from the atomizing core 220 and the atomizing core 220 is accidentally triggered and dry-burns.

[0088] like Figure 2 , Figure 3 The bottom cover assembly 30 includes a bottom shell 310, and the housing assembly 10 includes a housing shell 120 and a seal 130; the housing shell 120 has a first end and a second end opposite to each other. In some examples, the first end is the end closer to the bottom cover assembly 30, and the second end is the end farther away from the bottom cover assembly 30.

[0089] like Figure 2 , Figure 3 The outer casing 120 has an air outlet 121 disposed on the first end of the outer casing 120. The atomizing seat 210 extends from the first end of the outer casing 120 toward the second end of the outer casing 120. The end of the atomizing seat 210 away from the base portion 213 is movably connected to the air outlet 121. The bottom shell 310 is movably connected to the second end of the outer casing 120. The sealing member 130 is sealed between the outer casing 120 and the atomizing seat 210 to form a liquid storage cavity 110 between the outer casing 120, the air outlet 121, the atomizing seat 210 and the sealing member 130.

[0090] When the bottom shell 310 moves relative to the outer shell 120, the pushing part 311 cooperates with the base part 213 to drive the atomizing seat 210 to move relative to the sealing part 130, so that the sealing part 130 blocks or opens the liquid inlet hole 2121.

[0091] In some examples, the air outlet 121 is embedded in the end of the atomizing base 210 away from the base portion 213, and the cavity of the air outlet 121 is connected to the atomizing channel 211 of the atomizing base 210, thereby exporting the aerosol generated by the atomization operation in the atomizing channel 211.

[0092] In some examples, the seal 130 is provided with a guide surface on the side near the liquid storage cavity 110, and the guide surface is inclined toward the liquid inlet 2121. The liquid storage cavity 110 can be composed of two parts: one part is the cavity between the guide surface of the seal 130, the inner surface of the outer shell 120, and the outer surface of the atomizing seat 210, and the other part is the cavity between the inner surface of the outer shell 120 and the outer surface of the air outlet 121.

[0093] Under the action of external force, the pushing part 311 in the bottom cover assembly 30 and the base part 213 in the atomizing seat 210 come into contact with each other. The pushing part 311 pushes the base part 213, thereby pushing the entire atomizing seat 210 to move away from the bottom cover assembly 30. Since the outer shell 120 limits the periphery of the sealing member 130, the sealing member 130 is fixed relative to the outer shell 120, and the atomizing seat 210 moves relative to the sealing member 130.

[0094] When the bottom cover assembly 30 is in the first position, the seal 130 in the housing assembly 10 blocks the liquid inlet 2121 on the atomizing seat 210. As the bottom cover assembly 30 moves, the atomizing seat 210 moves relative to the seal 130. When the bottom cover assembly 30 moves to the second position, the liquid inlet 2121 is opened, and the atomizing matrix in the liquid storage chamber 110 then enters the atomizing channel 211 through the liquid inlet 2121.

[0095] like Figure 9 The bottom shell 310 has a mounting groove 314 on the side facing the atomizing base 210. The bottom shell 310 has a peripheral wall portion 312 and a bottom portion 313. The peripheral wall portion 312 of the bottom shell 310 is located at the end facing the atomizing base 210, and the bottom portion 313 of the bottom shell 310 is located at the end away from the atomizing base 210. The peripheral wall portion 312 and the bottom portion 313 enclose each other to form the mounting groove 314, which opens on the side facing the atomizing base 210.

[0096] like Figure 9The pushing part 311 protrudes from the bottom 313 into the mounting groove 314, and can then abut against the base part 213 of the atomizing seat 210. The length of the pushing part 311 can be less than the depth of the mounting groove 314. The mounting groove 314 can collect condensed material flowing out of the atomizing channel 211 (such as condensate from air and the tube wall of the atomizing seat, or un-atomized atomizing matrix). Furthermore, the mounting groove 314 contains a liquid suction element (not shown in the figure), which can adsorb the condensed material.

[0097] like Figure 11 A positioning part 3121 is provided on the side of the peripheral wall 312 facing the outer shell 120. If the positioning part 3121 is a positioning block, the outer shell is provided with a first positioning hole 122 and a second positioning hole 123. The first positioning hole 122 is set to a first position, and the second positioning hole is set to a second position. The first positioning hole 122 is closer to the bottom cover assembly 30 than the second positioning hole 123.

[0098] The positioning part 3121 is snapped into the first positioning hole 122 or the second positioning hole 123. When the bottom cover assembly 30 moves to the first position, the positioning part 3121 is snapped into the first positioning hole 122. When the bottom cover assembly 30 moves to the second position, the positioning part 3121 is snapped into the second positioning hole 123.

[0099] like Figure 3 The bottom shell 310 is provided with a guide post 315, which is embedded in the bottom 313 of the mounting groove 314. The length of the guide post 315 is greater than the depth of the mounting groove 314, that is, the guide post 315 extends out of the mounting groove 314. The guide post 315 and the positioning part 3121 are integrally formed. The sealing part 130 is provided with a guide hole 131, and the guide post 315 is slidably inserted into the guide hole 131.

[0100] Because the guide post 315 and guide hole 131 are provided, and the guide post 315 and positioning part 3121 are integrally formed, when the bottom cover assembly 30 moves relative to the atomizing seat 210, it can guide the bottom cover assembly 30 to move along the direction formed by the guide post 315 and guide hole 131. Thus, when the bottom cover assembly 30 is in the first position, the positioning part 3121 is snapped into the first positioning hole 122, and when it moves to the second position along the direction formed by the guide post 315 and guide hole 131, the positioning part 3121 is snapped into the second positioning hole 123.

[0101] In some examples, there can be multiple guide posts 315, such as two, and the number of guide holes 131 in the seal 130 can be the same as the number of guide posts 315.

[0102] like Figure 9The outer periphery of the peripheral wall portion 312 of the bottom cover assembly 30 is provided with a guide portion 3122 protruding outward. For example, the guide portion 3122 is elongated. Figure 2 The outer casing 120 is provided with a guide groove 124 on the side facing the peripheral wall 312. The shape of the guide groove 124 can be adapted to the shape of the guide part 3122, and the guide part 3122 is slidably connected in the guide groove 124.

[0103] When the bottom cover assembly 30 moves relative to the atomizer base 210, the guide portion 3122 in the bottom cover assembly 30 is connected to the guide groove 124 in the outer shell 120, which makes the movement of the bottom cover assembly 30 more stable and prevents it from shifting. As a result, the pushing portion 311 in the bottom cover assembly 30 can contact the base portion 213 in the atomizer base 210 after the movement and push the atomizer base 210 containing the base portion 213.

[0104] like Figure 10 The bottom shell component 310 of the bottom cover assembly 30 is also provided with an air intake channel 316, such as... Figure 7 An air inlet 2122 is provided on the side wall 212 of the base portion 213 in the atomizing seat 210, and the air inlet channel 316, the air inlet 2122, the atomizing channel 211 and the air outlet 121 are connected in sequence.

[0105] During atomization, gas enters the atomizer 1 through the air inlet channel 316 of the bottom cover assembly 30, and then enters the atomization assembly 20 through the air inlet 2122. In the atomizing core 220 of the atomization assembly 20, gas atomizes with the atomizing matrix. The aerosol generated during atomization enters the air outlet 121 of the housing assembly 10 through the atomization channel 211 in the atomizing base 210, and is then discharged through the air outlet 121. Furthermore, by changing the air inlet 2122 from the bottom 313 to the side, the risk of the air inlet 2122 being blocked by condensate collected in the mounting groove 314 is reduced, ensuring the normal operation of the atomizer and improving its e-liquid collection function.

[0106] like Figure 8 The outer surface of the side wall portion 212 in the atomizing base 210 is also provided with a ventilation groove 2123. The ventilation groove 2123 is located in the area between the liquid inlet hole 2121 and the base portion 213. One end of the ventilation groove 2123 is connected to the liquid inlet hole 2121, and the other end of the ventilation groove 2123 bends and extends from the liquid inlet hole 2121 toward the base portion 213. When the bottom shell 310 is in the second position, one end of the ventilation groove 2123 is connected to the liquid storage chamber 110 through the liquid inlet hole 2121, and the other end of the ventilation groove 2123 is connected to the air inlet channel 316.

[0107] Since the atomization operation requires the user to press the housing to start, different pressing pressures during the pressing process will cause different instantaneous pressures inside the liquid storage chamber 110. The pressure inside the liquid storage chamber 110 is difficult to release and may cause adverse phenomena such as the atomization mechanism overflowing from the atomizing core 220. By setting the ventilation groove 2123 to a curved structure, effective ventilation can be achieved, and it can also play a role in relieving pressure when the instantaneous pressure inside the liquid storage chamber 110 is high.

[0108] like Figure 2 , Figure 3 The bottom cover assembly 30 includes a bottom shell component 310, and the housing assembly 10 includes a housing component 120. The bottom shell component 310 is mounted on one end of the housing component 120, such as... Figure 9 The peripheral wall portion 312 of the bottom shell 310 can be inserted into the cavity of the outer shell 120, and the bottom portion 313 of the bottom shell 310 is limited to the cavity of the outer shell 120.

[0109] like Figure 10 The atomizer 1 also includes a circuit board 40, such as Figure 4 , Figure 5 , Figure 6 The atomizer 1 also includes an airflow sensor 50 (also known as a microphone). The airflow sensor 50 is disposed on the circuit board 40. The bottom shell 310 has a mounting structure 318 on the side opposite to the outer shell 120. The circuit board 40 and the airflow sensor 50 are mounted on the mounting structure 318.

[0110] Electrode assembly 3111 is inserted through bottom shell 310 and electrically connected to circuit board 40. Circuit board 40 is electrically connected to power supply assembly 2. Power supply assembly 2 can then supply power to electrode assembly 3111 through circuit board 40. When electrode assembly 3111 comes into contact with conductive wire 221 in atomizing core 220, current flows through conductive wire 221 to atomizing core 220, thereby enabling atomization.

[0111] like Figure 9 The bottom shell 310 has a detection air passage 317 on the side facing the outer shell 120. The atomization channel 211 is connected to the airflow sensor 50 through the detection air passage 317. When the user inhales through the air outlet, the air enters the airflow sensor 50 through the detection air passage 317, generating a certain pressure on the diaphragm of the airflow sensor 50. The airflow sensor 50 can detect the airflow pressure and thus control the atomizing core 220 to start or stop the atomization operation.

[0112] In some examples, the airflow sensor 50 can detect at preset time intervals, such as 3 to 25 seconds, or 25 seconds, 20 seconds, 16 seconds, 15 seconds, 10 seconds, 5 seconds, 3 seconds, etc. By setting the detection time interval, the power of the atomizer device can be saved.

[0113] The following is an illustrative description of the operation process of the atomizing device in this application:

[0114] 1. In the non-operating state, the bottom cover assembly 30 is in the first position, and the pushing part 311 in the bottom cover assembly 30 and the base part 213 of the atomizing seat 210 in the atomizing assembly 20 are spaced apart, and the electrode assembly 3111 on the pushing part 311 is not inserted into the limiting groove 2131 of the base part 213.

[0115] At this time, the seal 130 in the housing assembly 10 blocks the liquid inlet 2121 of the atomizer seat 210, blocking the connection between the liquid storage chamber 110 and the atomization channel 211 in the atomizer seat 210. This achieves the separation of the atomization matrix and the atomizing core 220 in the liquid storage chamber 110 when not in operation, i.e., "oil-core separation", reducing the occurrence of oil leakage problems. In addition, a safe distance is maintained between the bottom cover assembly 30 and the atomizer seat 210. During transportation, even if the bottom cover assembly 30 is subjected to a violent impact, the atomizer 1 will not be easily activated, thereby further preventing the occurrence of oil leakage problems and greatly improving the user experience.

[0116] Furthermore, since the electrode assembly 3111 on the pushing part 311 is not inserted into the limiting groove 2131 of the base part 213, the conductive wire 221 in the atomizing core is separated from the electrode assembly 3111, and no current flows to the atomizing core 220. The atomizing core 220 cannot perform atomization operations, thereby avoiding the situation where the atomizing matrix and the atomizing core 220 are separated in the liquid storage chamber 110 and the atomizing core 220 is accidentally triggered and dry-burned, i.e., "oil-electric separation".

[0117] 2. When the user wants to use the atomizing device for atomization, the user presses the housing assembly 10 towards the side of the bottom cover assembly 30. Since the bottom cover assembly 30 and the housing assembly 10 are connected, the bottom cover assembly 30 switches to the third position under the action of external force.

[0118] At this time, the electrode assembly 3111 on the pushing part 311 is inserted into the limiting groove 2131 in the base part 213. The electrode assembly 3111 then contacts the conductive wire 221 in the limiting groove 2131 to form an electrical connection. The current of the battery 24 in the power supply assembly 2 flows to the atomizing core 220 through the electrode assembly 3111 and the conductive wire 221, supplying power to the atomizing core 220. The atomizing core 220 then has the ability to perform atomization operations.

[0119] However, although the atomizing core 220 is powered and has the ability to perform atomization, the sealing element 130 in the housing assembly 10 still blocks the liquid inlet 2121 of the atomizing seat 210. The connection between the liquid storage chamber 110 and the atomization channel 211 in the atomizing seat 210 is still blocked. The atomizing matrix in the liquid storage chamber 110 is atomized into the atomization channel 211, and the atomizing core 220 cannot perform atomization.

[0120] 3. As the user continues to press the housing assembly 10 toward the side closer to the bottom cover assembly 30, the bottom cover assembly 30 gradually switches from the third position to the second position. When the bottom cover assembly 30 switches to the second position, the pushing part 311 in the bottom cover assembly 30 abuts against the base part 213 in the atomizer seat 210, thereby pushing the atomizer seat 210 to move relative to the housing assembly 10.

[0121] As the atomizing seat 210 moves relative to the housing assembly 10, the liquid inlet hole 2121 in the atomizing seat 210 is no longer blocked by the housing assembly 10. That is, the sealing element 130 opens the liquid inlet hole 2121, and the liquid storage chamber 110 is connected to the atomizing channel 211. The atomizing matrix in the liquid storage chamber 110 enters the atomizing channel 211, and the atomizing core 220 then uses the atomizing matrix that has entered the atomizing channel 211 to perform atomization.

[0122] The aerosol generated during the atomization operation enters the air outlet 121 in the housing assembly 10 through the atomization channel 211 in the atomizing seat 210, and is then discharged from the air outlet 121.

[0123] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
