Description

Technical Field

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

[0002] The atomizing device includes an atomizer and a power supply device electrically connected to the atomizer. The atomizer has an air inlet channel, a liquid storage chamber, an atomizing chamber, and an atomizing channel. The atomizing chamber is connected to the atomizing channel. The liquid storage chamber is used to store atomizing liquid. The atomizing liquid in the liquid storage chamber can enter the atomizing chamber and be heated to generate aerosol. The air inlet channel is connected to the atomizing chamber. Airflow enters the atomizing chamber from the air inlet channel. Under the suction action, the airflow and the aerosol generated in the atomizing chamber can be drawn out along the atomizing channel.

[0003] The temperature of the atomizing channel wall may be lower than the temperature of the aerosol. As the aerosol is discharged along the atomizing channel, it will come into contact with the channel wall and form condensate. Under the action of gravity, the condensate will flow out of the atomizer through the atomizing chamber and the air inlet channel, which may cause the atomizer to leak or cause the condensate to enter the power supply device, thus affecting the normal use of the atomizing equipment.

[0013] In one alternative embodiment, the atomizer has a mouthpiece channel communicating with the atomization channel, the mouthpiece channel extending in the extension direction of the atomization channel, the mouthpiece channel having an air inlet and an air outlet, and the cross-section of the mouthpiece channel perpendicular to its extension direction gradually increasing from the air inlet to the air outlet.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0026] 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).

[0027] This application discloses an atomizer used in atomizing equipment to heat the atomizing liquid to generate an aerosol for user use. By setting a liquid collection chamber 4 and a drainage section 532 inside the atomizer, the drainage section 532 guides the returned condensate into the liquid collection chamber 4, thereby collecting the returned condensate. This reduces the probability of condensate entering the air intake channel 534, thereby reducing the probability of atomizer leakage and helping to ensure the normal operation of the atomizing equipment.

[0028] Please refer to the atomizer in this embodiment of the application. Figure 1 and Figure 2 The atomizer has a liquid storage chamber 12, an atomizing chamber 21, an atomizing channel 22, and a liquid collection chamber 4. The liquid storage chamber 12 is used to store atomizing liquid. The atomizing chamber 21 is connected to the liquid storage chamber 12. The atomizing liquid in the liquid storage chamber 12 can enter the atomizing chamber 21 and be heated by the atomizing core 23 to generate aerosol in the atomizing chamber 21. The atomizing channel 22 extends in a first direction, which is also the up and down direction of the atomizer in use. The atomizing channel 22 is connected to the atomizing chamber 21 and can discharge the aerosol generated in the atomizing chamber 21.

[0029] The liquid collection chamber 4 is located on the side of the atomizing chamber 21 away from the atomizing channel 22 in the first direction. The liquid collection chamber 4 can be connected to the atomizing chamber 21 through the first channel 32. The first channel 32 extends in the first direction and has a cross-section perpendicular to its extension direction. The first channel 32 includes a small diameter section 321, and the cross-sectional dimension of the small diameter section 321 is the smallest among all the cross-sectional dimensions of the first channel 32.

[0030] In one embodiment, the cross-sectional shape of the first channel 32 is the same as that of the small-diameter segment 321, that is, the first channel 32 only includes the small-diameter segment 321. In another embodiment, the first channel 32 includes a large-diameter segment 322 in addition to the small-diameter segment 321. The large-diameter segment 322 is connected to the small-diameter segment 321, and the cross-sectional dimension of the large-diameter segment 322 is larger than that of the small-diameter segment 321.

[0031] In the atomizer of this application embodiment, the liquid collection chamber 4 has a first chamber wall 51 and a second chamber wall 33 arranged at intervals in a first direction. The first chamber wall 51 is located on the side of the second chamber wall 33 facing away from the atomization chamber 21 in the first direction. A boss 53 protruding towards the liquid collection chamber 4 is provided on the first chamber wall 51. The boss 53 extends in the first direction and has an air inlet channel 534 communicating with the liquid collection chamber 4. Gas from outside the atomizer can enter the liquid collection chamber 4 through the air inlet channel 534, enter the atomization chamber 21 along the first channel 32, and be discharged along the atomization channel 22 together with the aerosol generated in the atomization chamber 21.

[0032] For the boss 53, the boss 53 also has a drainage portion 532. The drainage portion 532 is located at the end of the boss 53 facing the atomizing chamber 21 in the extension direction of the boss 53, that is, in the first direction. The drainage portion 532 is directly opposite the first channel 32 in the first direction. In the plane perpendicular to the first direction, the orthographic projection of the small diameter section 321 in the first channel 32 is located in the orthographic projection of the drainage portion 532. That is, the maximum cross-sectional area of ​​the drainage portion 532 in the vertical first direction is greater than the cross-sectional area of ​​the small diameter section 321. The drainage section 532 can block the small diameter section 321, so that the condensate flowing back in the atomizing chamber 21 and the atomizing channel 22 will flow along the cavity wall of the atomizing chamber 21 into the first channel 32, and drip onto the drainage section 532 under the action of gravity at the end opening of the small diameter section 321. The drainage section 532 can guide the condensate to the liquid collection chamber 4, thereby reducing the probability of condensate entering the air intake channel 534, thus reducing the probability of atomizer leakage and helping to ensure the normal operation of the atomizer and the entire atomizing device.

[0033] In some embodiments, for the drainage portion 532 and the air intake channel 534 on the boss 53, the drainage portion 532 can be staggered from the air intake channel 534 in a plane perpendicular to the first direction. The air intake channel 534 is a straight channel, and the outlet of the air intake channel 534 faces the first direction. The air intake channel 534 is staggered from the small diameter section 321 in a plane perpendicular to the first direction to reduce the probability of condensate dripping into the air intake channel 534 under the action of gravity.

[0034] In some embodiments, please refer to Figure 2 The guide portion 532 can also be located on the side of the air intake channel 534 facing the atomizing chamber 21 in the first direction. The guide portion 532 encloses and forms part of the channel wall of the air intake channel 534. In the plane perpendicular to the first direction, a part of the orthographic projection of the air intake channel 534 is located in the orthographic projection of the guide portion 532. The guide portion 532 blocks a part of the outlet of the air intake channel 534 in the plane perpendicular to the first direction, so that the air intake channel 534 forms a bent channel, and the angle between the outlet of the air intake channel 534 and the first direction is an acute angle, which can reduce the probability of condensate dripping directly into the air intake channel 534 under the action of gravity.

[0035] Alternatively, it can be set in a plane perpendicular to the first direction, with the orthographic projection of the intake channel 534 entirely within the orthographic projection of the guide section 532. The guide section 532 blocks the outlet of the intake channel 534 in a plane perpendicular to the first direction, so that the intake channel 534 forms a bent channel, and the outlet of the intake channel 534 is perpendicular to the first direction, which can directly prevent condensate from dripping directly into the intake channel 534 under the action of gravity.

[0036] In some embodiments, please continue to refer to Figure 2 To ensure air intake, two air intake channels 534 are provided, or three or more can be provided. Two air intake channels 534 are arranged at intervals in the second direction, which is perpendicular to the first direction. The boss 53 has a connecting part 531 that connects the drainage part 532 and the first cavity wall 51. The connecting part 531 is located between the two spaced air intake channels 534. This can increase the receiving area of ​​the drainage part 532 for condensate while reducing the size of the boss 53 and facilitating the drainage part 532 to block the outlets of the air intake channels 534 on both sides.

[0037] To ensure that the drainage section 532 has a good drainage function, a drainage groove 533 is also provided in the drainage section 532. The opening of the drainage groove 533 faces the first channel 32, that is, the opening of the drainage groove 533 faces the first direction. The drainage groove 533 extends upward in a third direction, and the third direction is perpendicular to the first direction and the second direction. That is, the first direction, the second direction and the third direction are mutually perpendicular. The two sidewalls of the drainage groove 533 are arranged at intervals in the second direction. In this way, the condensate received can be collected in the drainage groove 533 through the bottom wall of the drainage groove 533, so that the condensate can flow directly to the bottom wall of the liquid collection chamber 4, that is, to the first chamber wall 51.

[0038] In some embodiments, the small diameter section 321 can be positioned in a plane perpendicular to the first direction, with its orthographic projection completely within the orthographic projection of the drainage groove 533. That is, in a plane perpendicular to the first direction, the small diameter section 321 is entirely located within the drainage groove 533. Alternatively, it can be understood that the maximum dimension of the small diameter section 321 in the second direction is smaller than the width of the drainage groove 533. This can prevent the condensate adhering to the channel wall of the small diameter section 321 from dripping directly onto the side wall of the drainage groove 533, and helps to ensure that all the condensate adhering to the channel wall of the small diameter section 321 can drip into the drainage groove 533 and flow to the first cavity wall 51 under the drainage effect of the drainage groove 533.

[0039] In other embodiments, the two sidewalls of the drainage channel 533 have two outer wall surfaces arranged opposite to each other, and the maximum dimension of the small diameter section 321 in the second direction can be smaller than the distance between the two outer wall surfaces; in addition, to prevent the condensate dripping on the sidewall of the drainage channel 533 from flowing along the outer wall surface to the air intake channel 534, the wall of the drainage channel 533 is provided with an end face facing the first channel 32, which is inclined inward toward the drainage channel 533 to form a guiding surface. This guiding surface is used to guide the condensate dripping on the sidewall of the drainage channel 533 into the drainage channel 533, so as to further reduce the probability of condensate entering the air intake channel 534.

[0040] In some embodiments, please refer to Figure 3 and Figure 4 For the boss 53, the boss 53 has two sides arranged opposite each other in the third direction. At least one of the two sides is provided with a drainage recess 535. The drainage recess 535 extends in the first direction and is connected to the drainage groove 533. In this way, the drainage recess 535 can guide the condensate in the drainage groove 533 to the bottom of the liquid collection chamber 4 under the action of gravity, that is, to the first chamber wall 51. This improves the drainage effect of the boss 53 on the condensate and further reduces the probability of the condensate entering the air intake channel 534.

[0041] In one embodiment, drainage recesses 535 can be provided on both sides, and the drainage recesses 535 on both sides in the third direction have a drainage function for condensate. In another embodiment, drainage recesses 535 can be provided on only one side, and the bottom wall of the drainage channel 533 can be inclined towards the drainage recess 535 in the first direction to facilitate the condensate in the drainage channel 533 to flow directly to the drainage recess 535 under the action of gravity.

[0042] In some embodiments, please refer to Figure 2 For the first channel 32, the first channel 32 has a first opening 323 communicating with the liquid collection chamber 4, and the air intake channel 534 has a second opening communicating with the liquid collection chamber 4. This second opening is the outlet of the air intake channel 534, and the orientation of the second opening is arranged at an acute angle to the first direction. In the plane perpendicular to the first direction, the edge of the first opening 323 is located outside the edge of the second opening and is spaced apart from the edge of the second opening. It can be understood that in the plane perpendicular to the first direction, the orthographic projection of the second opening is located within the orthographic projection of the first opening 323. In this way, the first opening 323 has a larger size, which can satisfy the requirement that the condensate that accumulates at the edge of the first opening 323 along the channel wall of the first channel 32 under the action of gravity can drip directly outside the second opening, that is, drip outside the air intake channel 534. This can prevent the condensate that accumulates at the edge of the first opening 323 from directly entering the air intake channel 534, which can further reduce the probability of atomizer leakage and help ensure the normal operation of the atomizer and atomization device. The rim of the first opening 323 can be understood as the edge or edge of the channel wall of the first channel 32 at the first opening 323, and the rim of the second opening can be understood as the edge or edge of the channel wall of the air intake channel 534 at the second opening.

[0043] The cavity wall of the liquid collection chamber 4 also includes a side cavity wall 52 connecting the first cavity wall 51 and the second cavity wall 33. In an embodiment where the boss 53 and the side cavity wall 52 are spaced apart, the minimum dimension of the first opening 323 in the second direction is set to be greater than the maximum dimension of the boss 53 in the second direction. This ensures that the condensate collected at the edge of the first opening 323 can drip directly into the liquid collection chamber 4, preventing the condensate from directly entering the air intake channel 534. Alternatively, in other embodiments, it is sufficient to ensure that the edge of the first opening 323 is not directly aligned with the second opening of the air intake channel 534 in the first direction.

[0044] In some embodiments, please continue to refer to Figure 2The liquid collection chamber 4 contains a liquid absorption element 6, which can be absorbent cotton. The liquid absorption element 6 is arranged around the boss 53 in a plane perpendicular to the first direction. The liquid absorption element 6 is used to absorb the condensate flowing into the liquid collection chamber 4 under the action of gravity. For example, the liquid absorption element 6 can absorb the condensate flowing into the liquid collection chamber 4 under the guidance of the drainage part 532 and under the action of gravity. In embodiments where the distance between the liquid absorption element 6 and the edge of the first opening 323 is small or the liquid absorption element 6 is in contact with the edge of the first opening 323, the liquid absorption element 6 can also absorb the condensate gathered at the edge of the first opening 323 under capillary action.

[0045] In some embodiments, please refer to Figure 2 The liquid collecting cavity 4 has a groove 536 arranged around the boss 53. The groove 536 can be an annular groove or a U-shaped groove. The first cavity wall 51 of the liquid collecting cavity 4 forms the bottom wall of the groove 536, and the side cavity wall 52 of the liquid collecting cavity 4 and the boss 53 form the side wall of the groove 536. The opening of the groove 536 faces the atomizing cavity 21 in the first direction. Part of the liquid suction member 6 or the entire liquid suction member 6 is located in the groove 536. The liquid suction member 6 and the bottom wall of the groove 536 are arranged at intervals in the first direction. After the liquid suction member 6 absorbs liquid, it can fill the atomizing cavity. The recess 535 allows the liquid suction member 6 to be interference-fitted with the side wall of the groove 536, so that after the liquid suction member 6 absorbs liquid, it can form a closed cavity 537 with the groove wall of the groove 536. The condensate absorbed by the liquid suction member 6 can flow to the closed cavity 537 under the action of gravity. The liquid suction member 6 can seal the closed cavity 537. During the shaking of the atomizer, the probability of the condensate in the closed cavity 537 flowing to the air intake channel 534 can be reduced. This can further reduce the probability of liquid leakage of the atomizer and ensure the normal operation of the atomizer and atomization equipment.

[0046] Of course, in other embodiments, the liquid suction member 6 can also be filled in the groove 536, and the liquid suction member 6 contacts the bottom wall of the groove 536. By increasing the volume of the liquid suction member 6, the liquid suction amount of the liquid suction member 6 can be increased, and the probability of condensate flowing to the air inlet channel 534 can be reduced.

[0047] In some embodiments, please refer to Figure 2 The atomizer comprises a shell 1, a tube 2, a bracket 3, and a base 5. The shell 1 extends in a first direction and has openings at both ends therein. The base 5 is sealed and installed at one end of the opening of the shell 1. The base 5 is connected to the shell 1 by a snap-fit. When the atomizer is in use, the base 5 is located at the bottom of the shell 1. The tube 2 and the bracket 3 are both located inside the shell 1. The tube 2 extends in the first direction, with one end sealingly fitted to the other end opening of the shell 1 and the other end sealingly fitted to the bracket 3. The bracket 3 and the base 5 are connected by a snap-fit ​​in the first direction. In this way, the tube 2 is clamped and fixed between the shell 1 and the bracket 3 in the first direction, thus ensuring the stability of the overall structure of the atomizer.

[0048] The outer shell 1, the tube body 2 and the support 3 enclose a liquid storage chamber 12. The atomizing channel 22 and the atomizing chamber 21 are both located inside the tube body 2. An atomizing core 23 is provided inside the atomizing chamber 21. The atomizing core 23 can absorb the atomized liquid in the liquid storage chamber 12 and heat the atomized liquid in the atomizing chamber 21 to generate an aerosol.

[0049] Please continue to refer to this. Figure 2 In some embodiments, the bracket 3 has a mounting ring groove 31 with a notch facing the atomizing chamber 21 in the first direction. The tube 2 is sealed and inserted into the mounting ring groove 31. The bracket 3 has a portion located inside the tube 2. The portion of the bracket 3 located inside the tube 2 and the portion of the bracket 3 located in the first direction facing the base 5 of the tube 2 together form a first channel 32. In addition to the small diameter section 321, the first channel 32 on the bracket 3 also includes a large diameter section 322. The large diameter section 322 is located on the side of the small diameter section 321 facing away from the atomizing chamber 21 in the first direction. The large diameter section 322 and the small diameter section 321 are connected by the channel wall and the chamfered surface in the first channel 32 perpendicular to the first direction. The large diameter section 322 is located at the end of the bracket 3 facing away from the tube 2 in the first direction. The edge of the first opening 323 is located on the end face of the bracket 3 facing away from the liquid storage chamber 12 in the first direction.

[0050] In other embodiments, the bracket 3 may be positioned outside the tube body 2, and the portion of the bracket 3 facing the base 5 in the tube body 2 in the first direction may form a first channel 32. The bracket 3 may include only the small diameter section 321, or it may include both the large diameter section 322 and the small diameter section 321. The edge of the first opening 323 is located on the end face of the bracket 3 facing away from the liquid storage cavity 12 in the first direction.

[0051] The liquid collection chamber 4 is located between the support 3 and the base 5 in the first direction. The first cavity wall 51 of the liquid collection chamber 4 is disposed on the base 5, the second cavity wall 33 is disposed on the support 3, the side cavity wall 52 is disposed on the base 5, and the boss 53 and the groove 536 are both disposed on the base 5.

[0052] In other embodiments, the bracket 3 and the base 5 can be integrally formed, or the outer shell 1 and the tube body 2 can be integrally formed.

[0053] In some embodiments, the atomizer has a mouthpiece channel 11 communicating with the atomization channel 22. The mouthpiece channel 11 is located at the opening at the other end of the housing 1 in the first direction. The mouthpiece channel 11 extends in the first direction and has an air inlet and an air outlet. The air outlet of the mouthpiece channel 11 communicates with the atomization channel 22 through the air inlet. The cross-sectional area of ​​the mouthpiece channel 11 in the vertical first direction gradually increases from the air inlet to the air outlet. When the atomizer is in use, the user's lips cover the mouthpiece. Under the action of suction, the aerosol in the atomization chamber 21 is discharged along the atomization channel 22 and the mouthpiece channel 11. Setting the cross-sectional area of ​​the mouthpiece channel 11 to gradually increase from the air inlet to the air outlet helps to increase the flow rate of the aerosol in the mouthpiece channel 11 and reduce the contact time between the aerosol and the channel wall of the mouthpiece channel 11. This reduces the probability of condensation due to contact between the aerosol and the channel wall of the mouthpiece channel 11, thereby reducing the generation of condensation from the source and reducing the probability of atomizer leakage.

[0054] Of course, in other embodiments, the cross-sectional dimensions of the suction channel 11 can be set to be equal everywhere, and the condensate can be recovered only through the liquid collection chamber 4 and the liquid suction element 6 to reduce the probability of atomizer leakage.

[0055] This application also discloses an atomizing device, which includes a power supply device and an atomizer as described in any of the above embodiments. The power supply device can be assembled together with the atomizer in the cylinder, or the atomizer can be inserted into the slot of the power supply device. The power supply device is electrically connected to the atomizer so as to supply power to the atomizer through the power supply device.
