[0012] Furthermore, the liquid locking part is a rectangular structure with a hollow middle, and a plurality of fins protruding inward are provided on the two long side walls of the liquid locking part. The two adjacent fins on the same long side wall and the long side wall form the liquid locking groove; there is a gap between the corresponding two fins on the two opposite long side walls.

[0013] Furthermore, the distance of the liquid locking gap in the direction of the line connecting the liquid locking member and the liquid absorbing surface is 0.5-1.0 mm.

[0014] Furthermore, the depth of the liquid locking groove is 0.1-0.6 mm, and the liquid locking groove (502) includes a lower opening and an upper opening located at opposite ends, and the lower opening is closer to the liquid absorption surface than the upper opening; the groove width of the liquid locking groove at the lower opening is 0.1-0.5 mm; in the extension direction from the upper opening to the lower opening, the opening angle range of the liquid locking groove is 3-15 degrees.

[0015] Furthermore, the two corresponding fins on the two relatively long side walls are connected.

[0016] Furthermore, the distance of the liquid locking gap in the direction of the line connecting the liquid locking member and the liquid absorbing surface is 0.4-1.5 mm.

[0017] Furthermore, the liquid locking member is fixedly connected to the atomizer seat via a snap-fit structure.

[0018] Furthermore, the heating element includes a sheet-shaped substrate and a heating element arranged on the surface of the substrate; the thickness of the substrate is 0.1-3.0 mm.

[0019] Furthermore, the heating element is arranged on the atomizing surface of the base, the liquid absorption surface is the other surface of the base facing away from the atomizing surface, and the base is provided with a liquid absorption channel running through the liquid absorption surface and the atomizing surface.

[0020] Furthermore, the liquid suction channel is a straight through hole, and the pore size of the straight through hole is 1-100 μm.

[0021] Furthermore, the atomizer seat includes an upper atomizer seat and a lower atomizer seat, the lower atomizer seat is sealed and connected to the open end of the shell, the upper atomizer seat is connected to the side of the lower atomizer seat facing the liquid storage chamber, and the liquid supply channel is arranged on the lower atomizer seat; the lower atomizer seat has an atomization chamber inside, and the lower atomizer seat is provided with an air inlet for external gas to enter the atomization chamber; the heating element is located between the upper atomizer seat and the lower atomizer seat, and the atomizing surface of the heating element is communicated with the atomization chamber.

[0022] Furthermore, the closed end of the shell is connected to an air guide pipe extending toward the liquid storage chamber and connected to the upper atomizer seat, and the upper atomizer seat is provided with an atomizing gas channel connecting the air guide pipe and the atomizing chamber.

[0023] Furthermore, the heating element is sealed and connected to the upper atomization seat via a first sealing member, and the liquid locking member is sealed and connected to the first sealing member.

[0024] The present application also provides an electronic atomization device, comprising a power supply and the atomizer as described above, wherein the power supply and the atomizer are electrically connected.

[0025] The technical solution provided by this application has the following advantages:

[0026] 1. The atomizer provided in the present application has a liquid locking member provided between the liquid supply channel of the atomizer seat and the liquid absorption surface of the heating element. The liquid locking member is provided with a liquid inlet communicating with the liquid supply channel and a liquid locking groove communicating with the liquid absorption surface. A liquid locking gap communicating with the liquid inlet and the liquid locking groove is formed between the end of the liquid locking member facing the heating element and the liquid absorption surface of the heating element. When the atomizer is placed in the forward direction, the liquid in the liquid storage chamber flows to the heating element through the liquid supply channel on the atomizer seat, the liquid inlet on the liquid locking member, and the liquid locking gap under the action of gravity, and remains in the liquid locking groove above the heating element. When the atomizer is tilted or inverted, although the liquid in the liquid storage chamber cannot flow to the liquid absorption surface of the heating element, the liquid absorption surface of the heating element can still absorb the liquid retained in the liquid locking groove under the capillary force, thereby avoiding the problem of dry burning of the heating element to produce a burnt smell or even burning the heating element on the heating element; in addition, the cross-sectional area of the liquid locking groove gradually decreases in the direction toward the liquid absorption surface. Such a setting can increase the capillary force of the liquid in the liquid locking groove, which helps the liquid in the liquid locking groove to flow to the liquid absorption surface of the heating element under the capillary force.

[0028] 3. The height of the liquid-locking gap in the atomizer provided herein is determined based on the installation angle. If the height of the liquid-locking gap is less than 0.5 mm, the liquid-locking component may easily come into contact with the liquid-absorbing surface during installation, thereby partially blocking the liquid-absorbing channel and easily crushing a very thin heating element. If the height of the liquid-locking gap is greater than 1.0 mm, bubbles may easily grow within the liquid-locking gap, thereby blocking the liquid-absorbing surface of the heating element.

[0040] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0041] The present application provides an atomizer, which is used to atomize liquid matrices such as flavor liquids and medicinal liquids. The atomizer 10 is used to store the liquid matrix and atomize the liquid matrix to form an aerosol that can be inhaled by a user.

[0042] like Figure 1-4As shown, the atomizer 10 includes a housing 1, an atomizer seat 20 and a heating element 4; the atomizer seat 20 includes an upper atomizer seat 2 and a lower atomizer seat 3. Among them, the housing 1 is a housing structure with an open end at one end and a liquid storage cavity 101 inside, and the liquid storage cavity 101 is used to store liquid matrix. The lower atomizer seat 3 is sealed and connected to the open end of the housing 1 and blocks the liquid storage cavity 101. The upper atomizer seat 2 is connected to the side of the lower atomizer seat 3 facing the liquid storage cavity 101, and a second sealing member 7 is provided between the upper atomizer seat 2 and the inner wall of the housing 1; the interior of the upper atomizer seat 2 is provided with a liquid supply channel 201 that communicates with the liquid storage cavity 101. The interior of the lower atomizing seat 3 is provided with an atomizing chamber 301, and the bottom of the lower atomizing seat 3 is provided with an air inlet for external gas to enter the atomizing chamber 301; the closed end of the housing 1 is connected with an air duct 102 extending to the liquid storage chamber 101 and connected to the upper atomizing seat 2, and the upper atomizing seat 2 is provided with an atomizing gas channel 202 connecting the air duct 102 and the atomizing chamber 301. The heating element 4 is located between the upper atomizing seat 2 and the lower atomizing seat 3, and the atomizing surface 402 of the heating element 4 is communicated with the atomizing chamber 301. The atomizing surface 402 of the heating element 4 generates an aerosol in the atomizing chamber 301, and the aerosol is introduced into the air duct 102 through the atomizing gas channel 202. The air duct 102 is used to guide the aerosol to the user's oral cavity through the aerosol outlet 103 on the housing 1.

[0043] like Figure 2-4 and Figure 6 As shown, the heating element 4 is in the form of a thin sheet, and the heating element 4 is sealed and connected to the bottom of the upper atomizing seat 2 through a first sealing member 6. The heating element 4 includes a thin sheet-shaped substrate and a heating element arranged on the substrate, and the thickness of the substrate is 0.1-3.0 mm; the atomizing surface 402 is a surface of the substrate, and the heating element is specifically a heating film 404 arranged on the atomizing surface of the substrate, and the heating film 404 is S-shaped in the middle part of the atomizing surface of the substrate. The substrate also has a liquid absorption surface that is connected to the liquid supply channel 201 in the upper atomizing seat 2, and the liquid absorption surface and the atomizing surface 402 are respectively the two opposite surfaces of the substrate; the liquid on the liquid storage chamber 101 can flow to the liquid absorption surface of the substrate through the liquid supply channel 201 and be absorbed by the substrate, and flow to the atomizing surface 402 of the substrate through the liquid absorption channel 403. The liquid aspiration channel 403 can be a microscopic pore provided on the substrate, with a pore size ranging from 1 to 100 μm. The substrate can be a dense substrate such as glass or ceramic, with the liquid aspiration channel 403 being a straight array of micropores extending through the liquid aspiration surface and the atomizing surface 402. Alternatively, the substrate itself can be a loose, porous structure such as porous ceramic or fiber cotton, allowing liquid to flow through the gaps in the porous structure into the atomizing surface 402 of the substrate. During operation, the heating film 404 heats the liquid on the atomizing surface 402 and atomizes it to form an aerosol.

[0044] A liquid-locking member 5 is further disposed between the liquid supply channel 201 and the liquid-absorbing surface of the heating element 4. This member is located directly above the liquid-absorbing surface and is sealed to the first sealing member 6. The member 5 comprises a liquid inlet 501 communicating with the liquid supply channel 201 and a liquid-locking groove 502 communicating with the liquid-absorbing surface. A liquid-locking gap 503 is formed between the end of the member 5 facing the heating element 4 and the liquid-absorbing surface of the heating element 4, connecting the liquid inlet 501 and the liquid-locking groove 502. The cross-sectional area of the liquid-locking groove 502 gradually decreases toward the liquid-absorbing surface.

[0045] The atomizer 10 is provided with a liquid locking member 5 above the liquid absorption surface of the heating element 4, a liquid inlet 501 communicating with the liquid supply channel 201 and a liquid locking groove 502 communicating with the liquid absorption surface are provided on the liquid locking member 5, and a liquid locking gap 503 communicating with the liquid inlet 501 and the liquid locking groove 502 is formed between the end of the liquid locking member 5 facing the heating element 4 and the liquid absorption surface of the heating element 4; when the atomizer 10 is placed in the forward direction, the liquid in the liquid storage chamber 101 passes through the liquid supply channel 201 on the upper atomizing seat 2 under the action of gravity. The liquid flows through the channel 201, the liquid inlet 501 on the liquid locking member 5, and the liquid locking gap 503 toward the heating element 4 and remains in the liquid locking groove 502 above the heating element 4; when the atomizer 10 is tilted or inverted, although the liquid in the liquid storage chamber 101 cannot flow to the liquid absorption surface of the heating element 4, the liquid absorption surface of the heating element 4 can still absorb the liquid retained in the liquid locking groove 502 under the capillary force, thereby avoiding the problem of dry burning of the heating element 4 to produce a burnt smell or even burning the heating element on the heating element 4.

[0046] Specifically, the liquid-locking groove 502 includes a lower opening and an upper opening at opposite ends, with the lower opening being closer to the liquid-absorbing surface than the upper opening. The cross-sectional area of the liquid-locking groove 502 gradually decreases as it extends from the upper opening to the lower opening. This arrangement enhances the capillary force of the liquid within the liquid-locking groove 502, helping it flow toward the liquid-absorbing surface of the heating element 4 under capillary action. In alternative embodiments, the liquid-locking groove 502 can also be configured with an open lower end and a closed upper end.

[0047] Combine Figure 5-6 As shown, in some embodiments, the liquid-locking member 5 is a rectangular parallelepiped structure with a hollow center. A plurality of inwardly protruding fins 504 are provided on two long side walls 506 of the liquid-locking member 5. Two adjacent fins 504 on the same long side wall 506 and the long side wall form a liquid-locking groove 502. A gap is provided between corresponding fins 504 on two opposing long side walls 506. The gap between the fins 504 facilitates the removal of bubbles generated on the liquid absorption surface of the heating element 4 and provides a larger liquid inlet area.

[0048] Specifically, the distance between the liquid-locking gap 503 and the liquid-absorbing surface is 0.5-1.0 mm. The height of the liquid-locking gap 503 is determined based on the installation angle. If the height of the liquid-locking gap 503 is less than 0.5 mm, the liquid-locking gap 503 may easily clash with the liquid-absorbing surface during installation, thereby partially blocking the liquid-absorbing channel 403 and easily crushing the thin heating element 4. When the height of the liquid-locking gap 503 is greater than 1.0 mm, bubbles may easily grow within the liquid-locking gap 503, thereby blocking the liquid-absorbing surface of the heating element 4.

[0049] Specifically, the depth of the liquid locking groove 502 is 0.1-0.6 mm, and the width of the liquid locking groove 502 at the lower opening is 0.1-0.5 mm; in the extension direction from the upper opening to the lower opening, the opening angle range of the liquid locking groove 502 is 3-15 degrees.

[0050] In some embodiments, the first sealing member 6 is annular, and an outer side of the first sealing member 6 is provided with a flange extending toward the outer wall of the heating element 4 to limit the heating element 4 .

[0051] In other embodiments, the two corresponding fins 504 on the two long side walls 506 are connected as a whole, and the distance between the liquid locking gap 503 and the line connecting the liquid locking member 5 and the liquid absorbing surface is 0.4-1.5 mm. This configuration can reduce the requirement for the distance of the liquid locking gap 503, allowing the distance of the liquid locking gap 503 to be selected within a relatively wider range, and also helps to retain more liquid in the liquid locking groove 502.

[0052] In some embodiments, the outer sides of the two long side walls 506 of the liquid locking member 5 are provided with outwardly protruding buckles 505, and the buckles 505 are provided with inclined guide surfaces. The liquid locking member 5 is snap-fitted with the upper atomizer seat 2 through the inclined guide surfaces on the buckles 505.

[0053] The present application also provides an electronic atomization device, comprising a power supply and an atomizer 10 connected to each other, wherein the power supply is used to power the atomizer so that the atomizer 10 can atomize a liquid matrix to form an aerosol.

[0054] To sum up, the atomizer and electronic atomization device provided by the present application are configured to provide a liquid locking component 5 having a liquid locking groove 502 above the liquid absorption surface of the heating element 4, and to form a liquid locking gap 503 between the liquid locking component 5 and the liquid absorption surface of the heating element 4. When the atomizer 10 is tilted or inverted, the liquid is cut off in the liquid locking gap 503, thereby locking the liquid in the liquid locking groove 502. The liquid absorption surface of the heating element 4 can absorb the liquid in the liquid locking groove 502, thereby avoiding the problem of the heating element 4 burning dry to produce a burnt smell or even burning the heating element on the heating element 4.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
