Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] Currently, common nebulizers with reservoir bottles require replenishing the nebulizer's reservoir with the stored nebulizer fluid when it runs out or becomes too low, allowing the device to continue operating. However, the current design of the relative positions of the reservoir bottle and the nebulizer in these technologies cannot accurately control the replenishment of the appropriate amount of nebulizer fluid based on actual conditions. This often results in excessive replenishment, leading to nebulizer leakage and negatively impacting the user experience. Utility Model Content

[0008] Both the inductive switch and the atomizer are electrically connected to the electronic control component. The inductive switch is used to identify whether the liquid replenishment component is in a liquid replenishment state. The electronic control component is used to control the working state of the atomizer according to the information identified by the inductive switch. When the liquid replenishment component is in a liquid replenishment state, the atomizer does not work.

The inductive switch includes a magnetic induction element and a magnetic induction unit. The magnetic induction element is fixed at the end of the switch away from the seal, and the magnetic induction unit is fixed inside the housing at the end near the fluid replenishment assembly.

[0010] In one embodiment, when the liquid inlet hole and the liquid inlet channel coincide, the magnetic induction unit and the magnetic induction element are misaligned; when the liquid inlet hole and the liquid inlet channel are misaligned, the magnetic induction unit and the magnetic induction element can be aligned.

[0011] The magnetic induction unit is used to sense the position of the magnetic induction element, and the electronic control component is used to control the working state of the atomizer based on the position information sensed by the magnetic induction unit.

[0012] In one embodiment, the magnetic sensing element is a magnet, and the magnetic sensing unit is a Hall switch; and / or, the outer wall of the liquid replenishment container is provided with a first marking structure, and the outer wall of the outer shell is provided with two second marking structures, wherein the first marking structure is used to cooperate with the second marking structure to indicate the current status of the atomizing device.

[0013] In one embodiment, the end of the switch facing the seal is provided with a liquid passage hole, and the end facing the atomizer is provided with a protruding liquid supply column. The liquid passage hole is in liquid communication with the liquid supply column to form the liquid supply channel.

[0014] In one embodiment, the device further includes a replenishment base, which is fixedly connected to the opening. The replenishment base is located at the end of the switch component away from the seal, and the magnetic induction component is fixed to the end of the replenishment base away from the seal. A positioning blind hole is formed at the end of the seal facing the replenishment base, a first clearance channel is formed on the switch component, a positioning component is provided at the end of the replenishment base facing the seal, the positioning component passes through the first clearance channel and the positioning blind hole, a second clearance channel is formed on the replenishment base, and the liquid supply column is used to pass through the second clearance channel and then insert into the injection hole.

[0015] In one embodiment, the liquid replenishment base has an assembly groove at one end facing the atomizer, and the magnetic induction element is fixed in the assembly groove; and / or, the electronic control assembly further includes a battery cell, and the end of the battery cell facing the atomizer is provided with a liquid suction element.

[0016] In one embodiment, the replenishment container includes a first tube and a second tube that are fitted together, with the second tube located inside the first tube; the sealing element, the switching element, and the replenishment base are all annular plates, and the sealing element, the switching element, and the replenishment base are all fitted together with the second tube.

[0017] In one embodiment, the atomizer includes a liquid storage assembly and an atomizing core assembly. The liquid storage assembly has an atomizing channel, and the atomizing core assembly is located within the atomizing channel. The liquid storage assembly has an injection hole at its upper part. The atomizing core assembly includes an atomizing core, an inner atomizing tube, a liquid storage component, and an outer atomizing tube. The atomizing core is sleeved within the inner atomizing tube, and the liquid storage component is sleeved between the inner atomizing tube and the outer atomizing tube. An air passage is formed within the replenishment container, and both the liquid storage component and the outer atomizing tube extend into the air passage.

[0018] In one embodiment, the device further includes a suction nozzle, which is fitted into the air passage at the bottom of the liquid replenishment container. The suction nozzle and the end of the atomizing outer tube near the bottom are fitted together, and the suction nozzle and the liquid storage device are axially spaced upwards.

[0019] According to the atomizing device in the above embodiments, a sealing element and a switching element are provided at the opening of the replenishment container. The sealing element has a liquid inlet hole, and the switching element has a liquid inlet channel extending through both ends. The liquid inlet channel connects to the injection hole located at the bottom of the replenishment assembly. Furthermore, the sealing element can rotate synchronously with the replenishment container. Thus, when it is necessary to inject replacement atomizing liquid into the atomizer, rotating the replenishment container will synchronously rotate the sealing element to align the liquid inlet hole and the liquid inlet channel, thereby completing the replenishment operation. The atomizer is located below the replenishment assembly, and the atomizing liquid can automatically flow from the replenishment assembly to the atomizer by gravity. After injecting the required amount of replacement atomizing liquid into the atomizer, rotating the replenishment container will synchronously rotate the sealing element, displacing the liquid inlet hole and the liquid inlet channel, thus ending the replenishment operation. The designed replenishment assembly is a replenishment structure that can rotate to open or close the liquid inlet channel at any time, facilitating control of the replenishment volume and effectively preventing leakage during replenishment. In addition, the nebulizer also includes a sensor switch and an electronic control component. The sensor switch can identify the current status of the liquid replenishment component, and the electronic control component controls the working status of the nebulizer based on the information identified by the sensor switch. When the liquid replenishment component is in the liquid replenishment state, the nebulizer cannot work. That is, the liquid replenishment component and the nebulizer in the designed nebulizer are used separately. This can avoid conflicts when the two are used at the same time and prevent the user from forgetting to turn off the liquid replenishment action. Attached Figure Description

At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] Please see Figures 1-4 In one embodiment of this application, an atomizing device is provided for replenishing the liquid storage chamber 21 in the atomizer. The atomizing device includes a liquid replenishment component 10, an atomizer 20 located below the liquid replenishment component 10, an electronic control component 60, and an inductive switch 70.

[0033] The fluid replenishment assembly 10 includes: a fluid replenishment container 11, a seal 12, and a switch 13.

[0034] The replenishment container 11 has a bottom 11a and an opening 11b, and the replenishment container 11 stores a replacement nebulizer fluid.

[0035] The sealing element 12 is disposed inside the opening 11b, and a liquid inlet 121 is provided on the sealing element 12.

[0036] The switch 13 is rotatably fixed inside the opening 11b. One end of the switch 13 is in contact with the end face of the seal 12 away from the bottom 11a. The switch 13 is provided with a liquid supply channel that runs through both ends of it. The upper part of the atomizer is provided with a liquid injection hole 221. The liquid supply channel of the switch 13 is connected to the liquid injection hole 221 and is restricted from rotation by the atomizer. The seal 12 is used to rotate synchronously with the replenishment container 11 so that the liquid supply hole 121 and the liquid supply channel are aligned or staggered.

[0037] It is understood that the seal 12 and the switch 13 are stacked, and in order to allow them to rotate relative to each other, one of them can be fixed while the other rotates. In some embodiments, the liquid supply channel of the switch 13 is connected to the liquid injection hole 221 and fixed relative to the atomizer, while the seal 12 rotates relative to the switch 13, so that the liquid supply channel coincides with or is offset from the liquid supply hole 121, thereby connecting or disconnecting the liquid supply channel.

[0038] The atomizer includes a liquid storage component 20 and an atomizing core component 30. The liquid storage component 20 has an atomizing channel, and the atomizing core component 30 is located in the atomizing channel. The upper part of the liquid storage component 20 has a liquid injection hole 221, and the liquid supply channel is connected to the liquid injection hole 221 located at the lower part of the liquid replenishment component 10.

[0039] Both the induction switch 70 and the atomizer core assembly 30 are electrically connected to the electronic control assembly 60. The induction switch 70 is used to identify whether the liquid replenishment assembly 10 is in the liquid replenishment state. The electronic control assembly 60 is used to control the working state of the atomizer core assembly 30 according to the information identified by the induction switch 70. When the liquid replenishment assembly 10 is in the liquid replenishment state, the atomizer core assembly 30 cannot work.

[0040] The atomizing device described in the above embodiment has a sealing element 12 and a switching element 13 in contact at the opening 11b of the replenishment container 11. The sealing element 12 has a liquid inlet hole 121, and the switching element 13 has a liquid inlet channel extending through both ends. The liquid inlet channel is connected to the liquid injection hole 221 located at the lower part of the replenishment assembly 10. The sealing element 12 can rotate synchronously with the replenishment container 11. Thus, when it is necessary to inject replacement atomizing liquid into the liquid storage assembly 20 of the atomizer, rotating the replenishment container 11 will synchronously rotate the sealing element 12 to align the liquid inlet hole 121 and the liquid inlet channel, thereby completing the replenishment operation. The atomizer is located below the replenishment assembly, and the atomizing liquid can automatically flow from the replenishment assembly 10 to the atomizer by gravity. After injecting the required amount of replacement atomizing liquid into the liquid storage assembly 20 of the atomizer, rotating the replenishment container 11 will synchronously rotate the sealing element 12 to displace the liquid inlet hole 121 and the liquid inlet channel, thus ending the replenishment operation. The designed liquid replenishment component 10 is a liquid replenishment structure that can be rotated to open or close the liquid supply channel at any time, facilitating control of the liquid replenishment volume and effectively preventing leakage during replenishment. In addition, the atomizing device includes a sensor switch 70 and an electronic control component 60. The sensor switch 70 can identify the current state of the liquid replenishment component 10, and the electronic control component 60 controls the working state of the atomizing core component 30 based on the information identified by the sensor switch 70. When the liquid replenishment component 10 is in the liquid replenishment state, the atomizing core component 30 cannot work. That is, the liquid replenishment component 10 and the atomizing core component 30 in the designed atomizing device are used in a staggered manner. This avoids conflicts when the two are used simultaneously and also prevents the user from forgetting to turn off the liquid replenishment.

[0041] It is understood that, after the replenishment component 10 in this application is assembled with the atomizer, the bottom 11a of the replenishment container 11 is located above the opening 11b.

[0042] Please see Figure 2 The switch element 13 has a liquid passage hole 131 at one end facing the seal element 12, and a protruding liquid supply column 132 at the other end facing the atomizer. The liquid passage hole 131 and the liquid supply column 132 are in liquid communication to form a liquid supply channel. The liquid supply column 132 is inserted into the injection hole 221. The outer diameter of the liquid supply column 132 can be equal to or slightly larger than the inner diameter of the injection hole 221 to ensure the sealing at the connection between the liquid supply column 132 and the injection hole 221.

[0043] Please see Figures 1-4The replenishment assembly 10 also includes a replenishment base 14, which is fixedly connected to the opening 11b. The replenishment base 14 is located at the end of the switch 13 away from the seal 12. A positioning blind hole 122 is provided at the end of the seal 12 facing the replenishment base 14. A first clearance track 133 is provided on the switch 13. A positioning element 141 is provided at the end of the replenishment base 14 facing the seal 12. The positioning element 141 passes through the first clearance track 133 and the positioning blind hole 122 and is sleeved thereon. A second clearance track 142 is provided on the replenishment base 14. The liquid supply column 132 is used to pass through the second clearance track 142 and then insert into the liquid injection hole 221 of the atomizer. The liquid supply hole 121 of the seal 122 and the liquid supply column 132 of the switch 13 form a channel for the atomized matrix stored in the replenishment container 11 to flow out.

[0044] The first avoidance track 133 is mainly designed to avoid the positioning component 141, and the second avoidance track 142 is mainly designed to avoid the liquid supply column 132, thus preventing interference with the rotation of the liquid replenishment base 14 (as well as the liquid replenishment container 11 and the seal 12). Based on the functions of the first avoidance track 133 and the second avoidance track 142, specifically, both the first avoidance track 133 and the second avoidance track 142 can be arc-shaped channels.

[0045] The positioning element 141 is, for example, a positioning post that matches the size of the positioning blind hole 122. By cooperating with the positioning element 141 on the liquid replenishment base 14 and the positioning blind hole 122 on the sealing element 12, the sealing element 12 and the liquid replenishment container 11 can rotate synchronously, thereby changing the position of the liquid inlet hole 121 on the sealing element 12 relative to the liquid passage hole 131 on the switch element 13, so that the user can freely control the liquid replenishment state.

[0046] Understandably, since the liquid supply column 132 on the switch 13 is inserted into the liquid injection hole 221 of the atomizer during liquid replenishment, the switch 13 remains stationary relative to the atomizer, meaning it does not rotate synchronously with the liquid replenishment container 11. Because the liquid replenishment container 11 rotates relative to the switch 13, and the sealing element 12 is sealed within the opening 11b, the overall shape of the liquid replenishment container 11, the sealing element 12, and the switch 13 are all cylindrical or disc-shaped. To ensure the consistency of the overall shape of the liquid replenishment assembly 10, the liquid replenishment base 14 can also be cylindrical or disc-shaped. Correspondingly, the liquid replenishment assembly 10 is cylindrical in this case, and the outer diameter of the liquid replenishment assembly can be the same as or compatible with the outer diameter of the atomizer, allowing for the storage of more replacement atomized liquid within the liquid replenishment assembly.

[0047] Please see Figures 5-8 The atomizing device also includes a housing 50, a liquid storage component 20, and an electronic control component 60, all of which are fixed inside the housing 50.

[0048] The inductive switch 70 is a magnetic induction switch. Specifically, the inductive switch 70 includes a magnetic induction element 71 and a magnetic induction unit 72. The magnetic induction element 71 is fixed to the end of the liquid replenishment base 14 away from the seal 12, and the magnetic induction unit 72 is fixed inside the end of the housing 50 near the liquid replenishment assembly 10.

[0049] The magnetic induction unit 72 is used to sense the position of the magnetic induction element 71. The electronic control assembly 60 includes a circuit board 61. The magnetic induction unit 72 is fixed to one end of the circuit board 61 near the liquid replenishment assembly 10, for example. The circuit board 61 is used to control the working state of the atomizing core assembly 30 based on the position information sensed by the magnetic induction unit 72. When the liquid inlet 121 and the liquid outlet 131 coincide, the magnetic induction unit 72 and the magnetic induction element 71 are misaligned. When the liquid inlet 121 and the liquid outlet 131 are completely misaligned, the magnetic induction unit 72 and the magnetic induction element 71 are aligned.

[0050] After the magnetic induction unit 72 and the magnetic induction element 71 are aligned, the magnetic induction unit 72 can sense the magnetic signal (i.e., the position information). For example, the magnetic induction element 71 is a magnet, and the magnetic induction unit 72 is a Hall switch. The magnetic induction unit 72 sends the magnetic signal to the circuit board 61, and the circuit board 61 activates the heating element 312 in the atomizing core 31 according to the magnetic signal (e.g., providing electrical energy to the heating element 312 and controlling the power supplied to the heating element 312).

[0051] Please see Figure 8 The outer wall of the liquid replenishment container 11 is provided with a first marking structure 1112, and the outer wall of the outer shell 50 is provided with two second marking structures 52. The first marking structure 1112 is used in conjunction with the second marking structures 52 to indicate the current status of the atomizing device.

[0052] The first marking structure 1112 can be a raised area, a groove, or a shape that provides a hint. Similarly, the second marking structure 52 can also be a raised area, a groove, or a shape that provides a hint. For example, the first marking structure 1112 is an inverted triangular groove, and the two second marking structures 52 are the letters A and B, respectively.

[0053] For example, when the first marking structure 1112 on the side wall of the replenishment container 11 is aligned with A on the outer shell 50, the magnetic induction element 71 is aligned with the magnetic induction unit 72, and the magnetic induction unit 72 can detect the magnetic signal. At this time, the nebulizer can heat and atomize the liquid to be atomized. Simultaneously, the liquid inlet hole 121 on the sealing element 12 and the liquid passage hole 131 on the switching element 13 are completely misaligned, and the sealing element 12 and the switching element 13 are in a misaligned sealing state, preventing the replacement atomizing liquid in the replenishment container 11 from being injected into the storage chamber. When the first marking structure 1112 on the side wall of the replenishment container 11 is aligned with B on the outer shell 50, the magnetic induction element 71 is completely misaligned with the magnetic induction unit 72, and the magnetic induction unit 72 cannot detect the magnetic signal. At this time, the nebulizer cannot heat and atomize the liquid to be atomized, and the user cannot inhale or use the nebulizer. This prevents the user from forgetting to turn off the liquid inlet. Simultaneously, the liquid inlet 121 on the seal 12 and the liquid passage 131 on the switch 13 are aligned, allowing the replacement atomizing liquid in the replenishment container 11 to be injected into the storage chamber. Once the liquid volume reaches the user's required level, the replenishment container 11 or the outer casing 50 is screwed on again, causing the first marking structure 1112 to rotate from B back to A, thus stopping the replenishment operation. The atomizing liquid can then be heated and atomized to the liquid to be atomized.

[0054] The state of the atomizing device can be switched by twisting the liquid replenishment container 11 or the outer shell 50. The state of the atomizing device can be switched quickly by the cooperation of the first marking structure 1112 and the second marking structure 52.

[0055] Please see Figure 1 and Figure 3 An assembly groove 144 is provided at one end of the liquid replenishment base 14 facing the liquid storage component 20, and the magnetic induction element 71 is fixed in the assembly groove 144. The assembly groove 144 can increase the assembly area of ​​the magnetic induction element 71 and ensure the assembly strength of the magnetic induction element 71.

[0056] Specifically, the side wall of the replenishment container 11 is provided with either a slot or a snap-fit ​​part, and the side wall of the replenishment base 14 is provided with the other slot or a snap-fit ​​part, and the slot and the snap-fit ​​part are connected by a snap-fit. For example, Figure 3As shown, two opposing slots 1111 are provided on the side wall of the opening 11b of the replenishment container 11, and two opposing engaging parts 143 are provided on the side wall of the replenishment base 14. The engaging parts 143 are blocks with guide engaging slopes. The two engaging parts 143 and the two slots 1111 are connected in a one-to-one snap-fit ​​connection to achieve a detachable fixed connection between the replenishment base 14 and the replenishment container 11. The detachable structural design between the replenishment base 14 and the replenishment container 11 facilitates the assembly of the replenishment component 10 and the replenishment of replacement atomizing fluid into the replenishment container 11, making the replenishment component 10 a reusable structure. In other embodiments, the replenishment base 14 can also be fixedly connected to the replenishment container 11 in a non-detachable manner, such as by adhesive bonding or welding.

[0057] Please see Figure 1 and Figure 3 Specifically, the replenishment container 11 includes a first tube 111 and a second tube 112 that are nested together, with the second tube 112 located inside the first tube 111. The first tube 111 and the second tube 112 are connected at one end of the bottom 11a to form a closed end, and the first tube 111 and the second tube 112 are nested together at one end of the opening 11b to form an open opening 11b.

[0058] The sealing element 12, the switching element 13, and the liquid replenishment base 14 are all annular plates, and they are all sleeved on the outer wall of the second tube 112. The sealing element 12 abuts against the inner wall of the first tube 111 and the outer wall of the second tube 112, respectively, that is, the sealing element 12 is tightly fitted to the inner wall of the first tube 111 and the outer wall of the second tube 112 to perform the sealing function of the sealing element 12.

[0059] The annular plate-shaped sealing element 12 and the switching element 13 are in surface-to-surface contact. When the liquid inlet hole 121 and the liquid outlet hole 131 are misaligned, the sealing element 12 and the switching element 13 are in a misaligned sealing state, thus preventing the replacement atomizing liquid in the replenishment container 11 from flowing out. The replenishment base 14 and the switching element 13 can be in surface-to-surface contact, partial contact, or spaced apart; this application does not impose specific limitations.

[0060] A stop portion 1121 is provided on the outer wall of the second tube 112, and the seal 12 abuts against the stop portion 1121. For example, Figure 3As shown, the stop portion 1121 is an annular stop surface formed by two cylindrical surfaces of different diameters on the outer wall of the second tube 112, which abuts against the axial end face of the seal 12. Alternatively, the stop portion 1121 may be a protruding plate, protruding ring, or other structure provided on the outer wall of the second tube 112, abutting against the axial end face of the seal 12. Yet another example is a protruding post provided on the outer wall of the second tube 112, with a groove formed at the end of the seal 12 facing the bottom 11a. The protruding post and the groove fit together, which better ensures the synchronous rotation of the seal 12 and the replenishment container 11. The designed stop portion 1121 restricts the installation position of the seal 12, preventing over-installation and ensuring the consistency of the replenishment assembly 10's manufacturing process.

[0061] Specifically, multiple liquid inlet holes 121 are configured, with liquid inlet holes 121, liquid passage holes 131, liquid inlet columns 132, and second clearance tracks 142 arranged in a one-to-one correspondence. Multiple positioning blind holes 122 are configured, with positioning blind holes 122, first clearance tracks 133, and positioning elements 141 arranged in a one-to-one correspondence. The number of liquid inlet holes 121 and positioning blind holes 122 can be the same or different.

[0062] For example, Figures 2-3 As shown, the liquid inlet 121, liquid passage 131, liquid inlet column 132 and second clearance track 142 are each configured in pairs. Taking the liquid inlet 121 as an example, the two liquid inlet 121 are symmetrically distributed about the axis of the liquid replenishment container 11. The positioning blind hole 122, the first clearance track 133 and the positioning element 141 are also each configured in pairs. Taking the positioning blind hole 122 as an example, the two positioning blind holes 122 are also symmetrically distributed about the axis of the liquid replenishment container 11.

[0063] When the liquid inlet hole 121 on the seal 12 and the liquid passage hole 131 on the switch 13 switch ... It is understandable that the term "overlapping" refers to the fact that the axes of the liquid supply hole 121 and the liquid passage hole 131 are aligned, while the term "completely offset" refers to the point where the liquid supply hole 121 and the liquid passage hole 131 are at their furthest circumferential distance.

[0064] In other embodiments, the number of liquid inlet holes 121 and liquid passage holes 131 can also be different, as can the number of liquid inlet columns 132 and the number of second clearance tracks 142. For example, four liquid inlet holes 121 can be configured, two liquid passage holes 131 and two liquid inlet columns 132 can be configured, and one second clearance track 142 can be configured. In this case, the arc angle of the second clearance track 142 needs to be increased to provide sufficient clearance space for the two liquid inlet columns 132 within it. Similarly, the configuration number of positioning blind holes 122, first clearance tracks 133, and positioning elements 141 can also be non-one-to-one, which will not be detailed here. Regarding the specific arrangement of liquid inlet holes 121, liquid passage holes 131, liquid inlet columns 132, second clearance tracks 142, positioning blind holes 122, first clearance tracks 133, and positioning elements 141, this application does not impose specific restrictions, as long as the liquid replenishment component 10 can control the liquid replenishment amount.

[0065] Specifically, multiple liquid inlet holes 121 and multiple positioning blind holes 122 are evenly distributed around the axis of the seal 12. By rotating the liquid replenishment container 11 at a preset angle, the multiple liquid inlet holes 121 and multiple liquid passage holes 131 can be aligned or completely offset. The preset angle of rotation of the liquid replenishment container 11 is determined based on the arc angle between the liquid inlet hole 121 and the adjacent positioning blind hole 122.

[0066] In other embodiments, the multiple liquid inlet holes 121 may also be located at different positions on the same radial line. In this case, the preset angle can be increased. For example, the preset angle of rotation of the liquid replenishment container 11 can be approximately 360 degrees.

[0067] Specifically, to facilitate liquid replenishment and control the replenishment volume, the diameter of the liquid inlet 121 is larger than that of the liquid passage 131, and the radial dimension within the liquid inlet column 132 can be equal to or smaller than the radial dimension of the liquid passage 131. For example, the diameter of the liquid inlet 121 is 1mm-10mm, and the diameter of the liquid passage 131 is 2mm-8mm.

[0068] The liquid storage assembly 20 includes a liquid storage chamber 21 and a sealing cap 22. The sealing cap 22 is fixed to the opening of the liquid storage chamber 21. The liquid storage chamber 21 and the sealing cap 22 together form a liquid storage cavity for storing the liquid to be atomized. The sealing cap 22 has an injection hole 221, which corresponds to the liquid supply column 132. The atomizing core assembly 30 is placed inside the liquid storage chamber 21 and is used to heat and atomize the liquid to be atomized.

[0069] To facilitate the connection between the replenishment component 10 and the storage component 20, the liquid column 132 and the injection hole 221 are tightly fitted or interference-fitted. Furthermore, a magnetic attraction structure can be provided between the replenishment base 14 and the sealing cap 22 to enhance the connection strength between the replenishment component 10 and the storage component 20. At the same time, it also facilitates the disassembly of the replenishment component 10 and the storage component 20 to facilitate the replacement of a new replenishment component 10.

[0070] It is understandable that the substitute atomizing liquid in the replenishment container 11 and the liquid to be atomized in the storage tank 21 are the same liquid, and the difference in their names is only for the convenience of describing and understanding the scheme.

[0071] The designed atomizing device is an electronic atomizing device with an upper-mounted replenishment container. Compared to a lower-mounted replenishment container, the upper-mounted container facilitates replenishment operations. Furthermore, by adopting the replenishment component 10 in the above embodiment, the replenishment operation can be started or stopped as needed when using the atomizing device.

[0072] Please see Figure 5 The atomizing core assembly 30 includes an atomizing core 31, an inner atomizing tube 32, a liquid storage component 33 (e.g., a liquid storage cotton), and an outer atomizing tube 34. The atomizing core 31 is fitted inside the inner atomizing tube 32, and the liquid storage component 33 is fitted between the inner atomizing tube 32 and the outer atomizing tube 34. An air passage is formed within the replenishment container 11 (second tube 112), and both the liquid storage component 33 and the outer atomizing tube 34 extend into the air passage. The liquid storage component 33 is annular cylindrical in shape, and its extension into the air passage allows for the absorption of more liquid to be atomized while effectively preventing leakage. The outer atomizing tube 34 extends into the air passage, providing support for the liquid storage component 33. The air passage is formed within the space of the second tube 112 of the replenishment container 11.

[0073] The atomizing core 31 includes a liquid guiding component 311 (e.g., a liquid guiding ceramic), a heating element 312, and a lead wire 313. The liquid guiding component 311 is annular and cylindrical, and is inserted into the inner wall of the atomizing inner tube 32. The heating element 312 is inserted into the inner wall of the liquid guiding component 311 and is a resistance heating structure such as mesh, filament, or sheet. The lead wire 313 is used to electrically connect the heating element 312 and the circuit board 61.

[0074] Please see Figures 5-6The atomizing device also includes a nozzle 40, which is fitted into the air passage at the bottom 11a of the liquid replenishment assembly 10. The nozzle 40 and the liquid storage container 33 are axially spaced upwards. This prevents the liquid from flowing out of the nozzle 40 if too much liquid is absorbed on the liquid storage container 33, thus preventing leakage, especially when the atomizing device is inverted. The structure is also more compact. In one embodiment, since the liquid replenishment assembly 10 and the atomizer are positioned vertically, the aerosol generated in the atomizer needs to flow out of the atomizing device from the top for user use. The air passage in the liquid replenishment assembly 10 connects to the atomizing air passage, and the outer wall of the bottom 11a of the liquid replenishment container 11 can also serve as the nozzle 40.

[0075] Please see Figures 5-6 The atomizer also includes an atomizing base 35 and a sealing base 36. The sealing base 36 is fixed to the bottom of the liquid storage chamber 21 to prevent leakage of the liquid to be atomized in the liquid storage chamber 21 at the bottom. For example, a recessed groove is opened in the bottom of the liquid storage chamber 21, and the sealing base 36 is tightly fitted into the recessed groove. The atomizing base 35 is sleeved inside the sealing base 36, and both the inner atomizing tube 32 and the outer atomizing tube 34 are sleeved with the atomizing base 35. For example, the atomizing base 35 includes an inner column and an outer column. The inner atomizing tube 32 is sleeved with the outer wall of the inner column, and the outer atomizing tube 34 is sleeved with the outer wall of the outer column. The lead wire 313 passes through the inner column and is electrically connected to the circuit board 61.

[0076] Specifically, multiple liquid inlet holes are provided on the side wall of the atomizing outer tube 34. These holes allow the liquid to be atomized in the storage tank 21 to flow into the storage component 33. Liquid outlet holes are provided at corresponding positions on the atomizing inner tube 32 and the atomizing core 31. These outlet holes are used to bring the storage component 33 and the liquid guiding component 311 into contact. To facilitate full utilization of the liquid to be atomized in the storage tank 21, the liquid inlet holes, liquid outlet holes, and atomizing core 31 are all located on the side near the bottom of the storage tank 21.

[0077] In other embodiments, the liquid storage component 33 can also be directly installed inside the entire liquid storage chamber. In this case, the atomizing outer tube 34 can be omitted, and the atomizing inner tube 32 can be retained. The suction nozzle 40 can be fixed to the second tube 112 of the replenishment container 11, or the suction nozzle 40 can be fixed to the sealing cap 22 corresponding to the atomizing inner tube 32.

[0078] Preferably, the atomizing device also includes a liquid level feedback structure, which is used to provide feedback on the content of the liquid to be atomized in the liquid storage tank 21. By providing timely feedback on the liquid level in the liquid storage tank 21 through the liquid level feedback structure, the phenomenon of clogging due to lack of timely liquid replenishment can be avoided, or the phenomenon of leakage due to excessive liquid replenishment and failure to stop the leakage in time can be avoided.

[0079] Specifically, the liquid level feedback structure is a viewing window 51 on the outer casing 50. The liquid storage tank 21 is made of transparent material. The viewing window 51 and the liquid storage tank 21 are positioned correspondingly. The user can directly see the content of the liquid to be atomized in the liquid storage tank 21 through the viewing window 51, and then decide whether to add liquid or stop adding liquid. Alternatively, the liquid level feedback structure includes a liquid level detection element and an alarm element, which are electrically connected to the electronic control component 60. The liquid level detection element is placed at the bottom of the liquid storage tank 21, and the alarm element is used to indicate the content of the liquid to be atomized in the liquid storage tank 21. For example, the liquid level detection element is a liquid level detection sensor, and the alarm element is an alarm light or an alarm horn.

[0080] Please see Figures 5-6 The electronic control assembly 60 also includes a battery cell 62 and an airflow detection element 63. The battery cell 62 and the airflow detection element 63 are electrically connected to the circuit board 61. The battery cell 62 is used to provide power to the heating element 312, and the airflow detection element 63 is used to detect air pressure to assist the circuit board 61 in controlling the working state of the heating element 312.

[0081] Specifically, the atomizing device also includes a bottom cover 80, a tubular outer shell 50, a sealing cap 22 abutting one end of the outer shell 50, and a bottom cover 80 abutting the other end of the outer shell 50. A sleeve is provided on the side of the bottom cover 80 facing the liquid storage tank 21, and the sleeve is sleeved onto the end of the liquid storage tank 21 away from the replenishment component 10. A battery cell 62 is fixed between the liquid storage tank 21 and the bottom cover 80 within the sleeve. A liquid suction element 621 is attached to the end of the battery cell 62 facing the liquid storage component 20, and the liquid suction element 621 is used to prevent the liquid to be atomized from leaking onto the battery cell 62. A first stop surface 211 is provided on the outer wall of the bottom of the liquid storage tank 21, and the sleeve abuts against the first stop surface 211. A second stop surface 222 is provided on the sealing cap 22, and the sealing cap 22 abuts against the end of the outer shell 50 through the second stop surface 222. An air inlet 81 is provided on the bottom cover 80, and an mounting sleeve 631 is provided inside the bottom cover 80 corresponding to the air inlet 81. The airflow detection element 63 is fixed inside the mounting sleeve 631. An insertion space is formed between the side wall of the outer shell 50, the side wall of the liquid storage tank 21, and the side wall of the battery cell 62. The circuit board 61 is inserted into the insertion space. For example, a first snap-fit ​​position 53 is provided on the side wall of the outer shell 50, and a second snap-fit ​​position 82 is provided inside the bottom cover 80. The circuit board 61 is snapped into the first snap-fit ​​position 53 and the second snap-fit ​​position 82 respectively.

[0082] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
