It is used to pass through the air inlet hole so that the sealing part can be pulled into the air inlet hole during the assembly operation of the sealing part.

[0022] And a limiting part, connected to the end of the sealing part away from the traction part, and having an outer diameter larger than the inner diameter of the air inlet hole, for limiting the insertion depth of the sealing part;

[0023] The end of the traction part connected to the sealing part has a breakable portion, and the diameter of the breakable portion is smaller than the diameter of the portion of the traction part outside the breakable portion.

[0036] Furthermore, the liquid-locking groove does not increase the size of the atomizer or the manufacturing cost, which is beneficial for design and manufacturing. Attached Figure Description

[0048] 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. In some cases, certain operations related to the present application are not shown or described in the specification. 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.

[0049] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. 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.

[0050] 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).

[0051] To address the leakage issue of the atomizer 10 during storage and use, one approach in related technologies involves providing a recovery chamber 15 at the bottom of the atomizer 10 to absorb and store leaked condensate. The recovered condensate includes the atomizing matrix leaking through the atomizing assembly 16 and the liquid that condenses and flows back during the suction process. However, during long-term storage and use of the atomizer 10, leakage still occurs due to insufficient volume in the recovery chamber 15. Increasing the volume of the recovery chamber 15 would increase the overall size of the atomizer 10.

[0052] Another approach is to design the atomizer 10 with a liquid-core separation structure, which keeps the atomizing component 16 and the atomizing matrix isolated during the storage stage, reducing the risk of leakage of the atomizing matrix through the atomizing component 16. It is then activated when needed, allowing the atomizing component 16 to absorb the heated atomizing liquid. However, this type of atomizer 10 has a complex structure and high design and manufacturing costs.

[0053] Therefore, there is an urgent need for an atomizer 10 that can improve the problem of insufficient liquid recovery capacity.

[0054] In this embodiment, by modifying the positioning structure between the mounting bracket 12 and the base 13, a liquid-locking groove 154 communicating with the recovery chamber 15 is formed between the positioning protrusion 131 and the positioning groove 121, thereby expanding the volume of the recovery space of the recovery chamber 15. This makes the recovery chamber 15 less likely to fill up, which helps to reduce the risk of leakage of the atomizer 10 during long-term storage and use, and improves the problem of insufficient liquid recovery capacity of the atomizer 10.

[0055] An embodiment of the atomizer in this application:

[0056] In some embodiments, please refer to Figure 1 and Figure 2 The atomizer 10 includes a housing 11, a mounting bracket 12, and a base 13.

[0057] The housing 11 can be understood as the main component constituting the outer contour of the atomizer 10. Please refer to [reference needed]. Figure 2 and Figure 3 The housing 11 has a mounting port 111 on one side for mounting other components of the atomizer 10 (such as mounting bracket 12, base 13, etc.) into the housing 11. An aerosol outlet 112 may be provided on the side of the housing 11 away from the mounting port 111, so that the atomizer 10 has... Figure 3 The aerosol outlet 112 is shown at the top and the mounting port 111 is at the bottom in the usage state, viewed from a medium angle. In order to reduce the leakage of condensate from the aerosol outlet 112 to the outside of the atomizer 10, a sealing plug 113 can be installed at the aerosol outlet 112 to seal the aerosol outlet 112 during the storage process and usage intervals of the atomizer 10.

[0058] Please refer to Figure 2 and Figure 3 The mounting bracket 12 is disposed within the housing 11, and together with the housing 11, defines the liquid storage chamber 14 for storing the atomized matrix. Exemplarily, the cross-sectional dimensions of the mounting bracket 12 are adapted to the cross-sectional dimensions of the inner cavity of the housing 11, and the material of the mounting bracket 12 can be an elastic material such as silicone, so that after the mounting bracket 12 is inserted into the housing 11 through the mounting port 111, it can be sealed and locked in the housing 11, so as to form the liquid storage chamber 14 with the housing 11 on the side near the aerosol outlet 112.

[0059] Please refer to Figure 2 and Figure 3 The base 13 is fitted onto the mounting port 111 to close the mounting port 111, thereby forming the outer contour of the atomizer 10 together with the housing 11, and protecting the mounting bracket 12 and other components located inside the atomizer 10.

[0060] Please refer to Figures 3 to 5 One of the base 13 and the mounting bracket 12 is provided with a positioning protrusion 131, and the other is provided with a positioning groove 121. The positioning protrusion 131 is inserted into the positioning groove 121 so as to achieve mutual positioning of the base 13 and the mounting bracket 12 during assembly. In some embodiments, both the base 13 and the mounting bracket 12 may be provided with positioning protrusions 131 and positioning grooves 121, which can cooperate to perform positioning.

[0061] Since the main function of the atomizer 10 is to heat the atomizing substrate to generate an aerosol, the atomizer 10 also includes an atomizing component 16. The atomizing component 16 is mounted on the mounting bracket 12 and is in fluid communication with the liquid storage chamber 14. The atomizing component 16 has an atomizing air passage 162. The atomizing component 16 heats the atomizing substrate to form an aerosol, which is then output through the atomizing air passage 162. The inlet end of the atomizing air passage 162 can be connected to the external environment of the atomizer 10 to allow external gas to enter, while the outlet end of the atomizing air passage 162 can be connected to the aerosol outlet 112 to allow the generated aerosol to be discharged, thereby establishing a pressure-balanced aerosol transport system. During storage and use, condensate can easily leak from the atomizer 10 to the outside through the atomizing air passage 162.

[0062] To reduce the risk of condensate leakage to the outside of the atomizer 10, in some embodiments, please refer to Figure 3The base 13 and mounting bracket 12 form a recovery chamber 15, which communicates with the atomizing air passage 162 to recover the condensate flowing back from the atomizing air passage 162. The recovery chamber 15 can be located on the side of the liquid storage chamber 14 away from the aerosol outlet 112. A liquid-absorbing element 151, such as absorbent cotton or porous ceramic liquid absorber, can be installed in the recovery chamber 15 to absorb the condensate. Furthermore, the peripheral wall of the liquid-absorbing element 151 can fit against the side wall of the recovery chamber 15 to be positioned within the recovery chamber 15.

[0063] In some embodiments, the base 13 may have a positioning protrusion 131 on the side facing the mounting bracket 12. The positioning protrusion 131 is arranged in a ring to surround a receiving groove 1312 that forms an opening facing the mounting bracket 12. The mounting bracket 12 may include a mounting portion 128 facing the base 13. The positioning groove 121 is arranged in a ring on the mounting portion 128. The positioning protrusion 131 is positioned and mounted in the positioning groove 121 so that the mounting portion 128 is partially inserted into the receiving groove 1312. The mounting portion 128 and the groove wall of the receiving groove 1312 surround each other to form a recycling cavity 15.

[0064] With long-term storage and use of the atomizer 10, once the recovery chamber 15 is full, condensate will still leak out. However, directly enlarging the recovery chamber 15 would increase the size of the atomizer 10 and raise manufacturing costs.

[0065] In some embodiments, please refer to Figure 2 and Figure 3 At least one of the positioning protrusion 131 and the positioning groove 121 has a liquid-locking groove 154 on its sidewall, and the end of the liquid-locking groove 154 communicates with the recovery chamber 15. Figure 2 The end of the liquid-locking groove 154 refers to the end of the liquid-locking groove 154 near the base 13, and is configured to contain and lock the condensate overflowing from the recovery chamber 15. When the recovery chamber 15 is full, the condensate will come into contact with the liquid-locking groove 154 and be pulled upward by the capillary action of the liquid-locking groove 154, thereby achieving the liquid-locking effect. The liquid-locking groove 154 expands the volume of the recovery space of the recovery chamber 15 to accommodate the excess condensate that leaks into the recovery chamber 15, thereby improving the condensate recovery capacity of the atomizer 10.

[0066] In some embodiments, the liquid-locking groove 154 includes a capillary gap 152, formed by a spaced interval between the sidewall of the positioning protrusion 131 and the groove sidewall of the positioning groove 121. The capillary gap 152 communicates with the recovery chamber 15 and is used to absorb condensate through capillary force, reducing the risk of condensate leakage to the atomizer 10 due to excessive hydraulic pressure in the recovery chamber 15. In some embodiments, the thickness of the positioning protrusion 131 may be 0.2mm-0.3mm less than the width of the positioning groove 121, so that a capillary gap 152 with a width of 0.2mm-0.3mm is formed between the sidewall of the positioning protrusion 131 and the groove sidewall of the positioning groove 121. Exemplarily, the sidewall of the positioning protrusion 131 facing away from the recovery chamber 15 may fit against the groove sidewall of the positioning groove 121, so that a capillary gap 152 is formed between the sidewall of the positioning protrusion 131 facing the recovery chamber 15 and the other groove sidewall of the positioning groove 121. Since the capillary gap 152 can be formed by adjusting the size of the positioning groove 121 and / or the positioning protrusion 131, it helps to expand the volume of the recovery chamber 15 without increasing the volume and cost of the atomizer 10. Furthermore, since the capillary gap 152 is formed on the inner side of the annular positioning protrusion 131, it is also an annular structure, which helps to obtain a larger expanded capacity.

[0067] In some embodiments, a sealing ring may be provided on the sidewall of the positioning groove 121 away from the recovery chamber 15 to improve the sealing effect. In addition, in order to facilitate precise positioning between the positioning protrusion 131 and the positioning groove 121, a notch 1311 may be provided on the positioning protrusion 131, and a ridge 1211 may be provided in the positioning groove 121 at the position corresponding to the notch 1311, so as to improve the assembly accuracy and assembly stability by using the engagement of the ridge 1211 and the notch 1311.

[0068] In some embodiments, please refer to Figure 5 The liquid-locking groove 154 may further include a plurality of receiving sub-grooves 153 communicating with the capillary gap 152. The receiving sub-grooves 153 are used to retain the condensate absorbed by the capillary gap 152. The plurality of receiving sub-grooves 153 are disposed on the sidewall of the positioning groove 121 facing the capillary gap 152, and can be arranged at intervals along the extending direction of the capillary gap 152. The above-described arrangement of the receiving sub-grooves 153 facilitates integral processing with the capillary gap 152, helping to save processing costs. It is understood that in other embodiments, the location, number, and size of the receiving sub-grooves 153 are not limited, as long as they meet design and usage requirements.

[0069] In other embodiments, the liquid-locking groove 154 may also be provided at other locations on the cavity wall of the recovery chamber 15 to lock the condensate in the recovery chamber 15 and limit the movement of the condensate.

[0070] In some embodiments, please refer to Figure 6 and Figure 7 The base 13 is provided with an air inlet hole 132. The atomizer 10 also includes a sealing member 17 for sealing the air inlet hole 132. The sealing member 17 includes a sealing part 172, a traction part 171, and a limiting part 173. The sealing part 172 is used to insert into and seal the air inlet hole 132. The traction part 171 is connected to the insertion end of the sealing part 172 and has an outer diameter smaller than the inner diameter of the air inlet hole 132. It is used to pass through the air inlet hole 132 so that the sealing part 172 can be inserted into the air inlet hole 132 during the assembly operation of the sealing member 17. The limiting part 173 is connected to the end of the sealing part 172 away from the traction part 171 and has an outer diameter larger than the inner diameter of the air inlet hole 132. It is used to limit the insertion depth of the sealing part 172. The end of the traction part 171 connected to the sealing part 172 has a breakable part 1711. The diameter of the breakable part 1711 is smaller than the diameter of the part of the traction part 171 outside the breakable part 1711, so as to form a weakened structure that can be pulled off by the operator.

[0071] When assembling the atomizer 10, the sealing part 17 can be pre-installed on the base 13. During assembly, first insert the traction part 171 from one side of the bottom surface of the base 13 into the air inlet hole 132, and then extend the traction part 171 from the other side of the air inlet hole 132. Then pull the traction part 171 to pull the sealing part 172 into the air inlet hole 132 until the limiting part 173 and the bottom surface of the base 13 abut. Then continue to pull the traction part 171 so that the traction part 171 breaks from the easily broken part 1711, and the sealing part 172 seals the air inlet hole 132. After that, the base 13 is assembled into the mounting port 111 of the housing 11.

[0072] By providing the traction part 171 to assist in the assembly of the sealing part 172, the assembly difficulty of the sealing part 17 is reduced, and the assembly quality is maintained, allowing the sealing part 17 to achieve the designed sealing effect. The inclusion of the breakable part 1711 facilitates the removal of the traction part 171, preventing it from occupying the internal space of the atomizer 10, and also helps to avoid interference between the traction part 171 and the assembly of the base 13.

[0073] It is understandable that the same sealing element 17 can be provided with multiple sealing parts 172 and traction parts 171. Please refer to [reference needed]. Figure 6 The sealing member 17 has two sealing portions 172, each connected to a traction portion 171, so that the same sealing member 17 can be used to seal two air intake holes 132. Alternatively, it can be understood that the two sealing members 17 share the same traction portion 171. In short, the number of sealing portions 172 on the sealing member 17 is not limited, as long as it can seal the air intake holes 132.

[0074] In some embodiments, please refer to Figure 7The air inlet 132 may also be provided with a stepped surface 1321. The distance from the stepped surface 1321 to the air inlet end of the air inlet 132 is adapted to the length of the sealing part 172. The stepped surface 1321 is configured to limit the displacement of the sealing part 172 when the traction part 171 is pulled off, thereby reducing the risk of excessive deformation of the sealing part 172 due to the pulling of the traction part 171, which could lead to seal failure. Here, "the distance from the stepped surface 1321 to the air inlet end of the air inlet 132 is adapted to the length of the sealing part 172" can be understood as: the distance from the stepped surface 1321 to the air inlet end of the air inlet 132 is equal to or slightly greater than the length of the sealing part 172, thereby avoiding excessive deformation of the sealing part 172.

[0075] In some embodiments, please refer to Figure 8 The mounting bracket 12 is provided with an air passage 122 for communicating with the gas through the air inlet 132. The atomizer 10 also includes an atomizing tube 161 for mounting the atomizing assembly 16. One end of the atomizing tube 161 can be mounted on the mounting bracket 12 and coaxially arranged with and communicating with the air passage 122; the other end is located in the liquid storage chamber 14 and communicates with the gas through the aerosol outlet 112. The atomizing tube 161 is provided with a communication port 1613 corresponding to the atomizing assembly 16, through which the atomizing assembly 16 can absorb and heat the atomizing matrix stored in the liquid storage chamber 14.

[0076] In some embodiments, please refer to Figure 3 and Figure 8 The housing 11 includes a tube portion 114 located within the housing 11. One end of the tube portion 114 has an aerosol outlet 112, and the other end has a connection port 1141. The atomizing tube 161 has a plug section 1611, which is inserted into the connection port 1141, so that the plug section 1611 and the cavity of the tube portion 114 form an air outlet channel for aerosol output. A sealing sleeve 164 is fitted on the outer side of the plug section 1611 to seal the gap between the plug section 1611 and the connection port 1141. A protruding structure 1612 is provided on the outer wall of the plug section 1611 to restrict the position of the sealing sleeve 164, so that the sealing sleeve 164 can be inserted into the connection port 1141 along with the plug section 1611, which helps to reduce the risk of sealing failure caused by displacement of the sealing sleeve 164 due to friction during assembly.

[0077] It is understood that the specific formation method of the protrusion structure 1612 is not limited, as long as it can limit the sealing sleeve 164. For example, the atomizing tube 161 can be a metal tube, and the protrusion structure 1612 can be formed by a portion of the middle section of the atomizing tube 161 protruding outward after the two sides of the atomizing tube 161 are compressed towards each other.

[0078] In some embodiments, please refer to Figure 8The atomizer 10 also includes an electrode 133, and the mounting bracket 12 is provided with a wire-through blind hole 123 and an electrode hole 125. The atomizing assembly 16 has a pin 163, which passes through the wire-through blind hole 123 and extends to the electrode hole 125. The electrode 133 is disposed on the base 13 and passes through and extends to the electrode hole 125 to be electrically connected to the pin 163.

[0079] For example, the mounting bracket 12 has a blind hole 123 near the base 13 for the pin 163 to pass through. The bottom wall of the blind hole 123 can be elastic so that after the pin 163 pierces through the bottom wall of the blind hole 123, the bottom wall of the blind hole 123 can seal the gap created by the pin 163 piercing through, which helps to reduce the risk of condensate leakage through the blind hole 123.

[0080] Please refer to Figure 8 The electrode 133 has a power receiving end 1331 and a connecting end 1332. The power receiving end 1331 is exposed outside the base 13, and the connecting end 1332 protrudes from the base 13 and is inserted into the electrode hole 125. One end of the lead 163 that passes through the blind hole 123 can extend into the electrode hole 125 and be sandwiched between the hole wall of the electrode hole 125 and the connecting end 1332 to make contact and conduct electricity with the connecting end 1332.

[0081] In one embodiment, a wire groove 124 may be provided between the blind hole 123 and the electrode hole 125, and the lead 163 passes through the blind hole 123 and extends into the electrode hole 125 through the wire groove 124. The blind hole 123, the wire groove 124 and the electrode hole 125 may each be provided in two sets symmetrically relative to the airway hole 122.

[0082] When the atomizer 10 is in use, as the atomizing matrix in the reservoir 14 is consumed, the pressure inside the reservoir 14 will gradually decrease. If it is not replenished in time, it will affect the supply of the atomizing matrix. Therefore, in some embodiments, please refer to... Figure 8 and Figure 9 The mounting bracket 12 may be provided with an insertion hole 126 for inserting and fixing the atomizing tube 161. The wall of the insertion hole 126 may be provided with an air guide groove 127. One end of the air guide groove 127 is connected to the gas inlet 132, and the other end extends to the wall of the liquid storage chamber 14 to communicate with the liquid storage chamber 14, so that external gas can enter the liquid storage chamber 14 through the air guide groove 127 to supplement the pressure in the liquid storage chamber 14.

[0083] In order to limit the leakage of the atomized matrix in the liquid storage chamber 14 through the air guide groove 127, the air guide groove 127 can be designed with a meandering bend, such as a serpentine shape, to reduce the risk of the atomized matrix leaking from the air guide groove 127.

[0084] For example, one end of the air guide groove 127 extends to the cavity wall of the liquid storage chamber 14, and the other end extends to the side wall of the wire-through blind hole 123, so that the air guide groove 127 communicates with the air inlet hole 132 through the wire-through blind hole 123, so that external gas is replenished into the liquid storage chamber 14 through the air guide groove 127.

[0085] Examples of electronic atomizing devices in this application:

[0086] In some embodiments, please refer to Figure 10 The electronic atomizing device includes the atomizer 10 and the power supply component 20 in any of the above embodiments. The power supply component 20 is electrically connected to the atomizer 10 and is used to supply power to the atomizer 10.

[0087] The power supply component 20 and the atomizer 10 can be either fixedly connected or detachably connected. When the atomizer 10 and the power supply component 20 are detachably connected, the atomizer 10 and the power supply component 20 can be replaced depending on the usage.

[0088] 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.
