[0034] This application provides an atomizer 10, such as... Figures 1 to 3 As shown, the atomizer 10 includes a mouthpiece 110, a liquid storage chamber 120, an atomizing core 130, and a liquid blocking element 140. The mouthpiece 110 is connected to the atomization channel 1301 of the atomizer 10. The liquid storage chamber 120 is used to store the atomizing matrix. The atomizing core 130 is used to heat the atomizing matrix in the liquid storage chamber 120 to form an aerosol. The liquid blocking element 140 is located at the end of the atomization channel 1301 away from the mouthpiece 110, and is used to block the atomizing matrix that leaks from the atomizing core 130. The atomizer 10 provided in this application, by providing a liquid blocking element 140 at one end of the atomization channel 1301, blocks or prevents the atomizing matrix and other liquids that leak from the atomizing core 130, thus preventing the atomizing matrix from leaking to the outside of the atomizer 10, which is beneficial to improving the anti-leakage effect of the atomizer 10 and improving the reliability of the atomizer 10.

[0035] In one embodiment, such as Figure 3As shown, the first air guide tube 111 and the nozzle 110 are integrally formed. A portion of the atomizing tube 131 is inserted into the first air guide tube 111 and is sealed to the first air guide tube 111. A liquid blocking element 140 is provided at the end of the first air guide tube 111 (i.e., upstream in the air intake direction). The liquid blocking element 140 is configured to allow airflow to pass through, but can block or prevent liquid leakage. Since the liquid blocking element 140 is configured as a planar, porous plate structure in this embodiment, this structure cannot completely prevent liquid leakage, but can only play a blocking role. When liquid leaks, it will be absorbed by the liquid suction element 170 below, while the liquid accumulated above the liquid blocking element 140 may be reabsorbed and atomized by the atomizing core 130.

[0036] In some embodiments, such as Figure 5 As shown, the liquid blocking component 140 is provided with a plurality of vent holes 1401. The atomizing channel 1301 passes sequentially through the vent holes 1401 of the liquid blocking component 140, the atomizing core 130, and the nozzle 110. External air can flow along the atomizing channel 1301 and enter the atomizing core 130 through the vent holes 1401, mix with the aerosol formed inside the atomizing core 130, and be discharged from the nozzle 110. The vent holes 1401 are configured to allow gas to pass through while obstructing the passage of the atomizing matrix.

[0037] In some embodiments, the diameter of the vent 1401 is 0.15 mm to 0.3 mm. Due to surface tension, the atomizing matrix cannot pass through the vent 1401, while gas molecules, due to their small size and high kinetic energy, can pass through. If the diameter of the vent 1401 is too large, the atomizing matrix may directly penetrate into the vent 1401; if the diameter of the vent 1401 is too small, it may affect the passage of gas through the vent 1401. By setting the vent 1401 to a suitable diameter range, the liquid blocking component 140 can achieve the effect of allowing gas passage while blocking the atomizing matrix.

[0038] In some embodiments, the diameter of the vent 1401 is 0.15 mm, 0.156 mm, 0.2 mm, 0.25 mm, 0.276 mm, 0.3 mm, or any value between the above diameters.

[0039] In some embodiments, there are multiple vent holes 1401, and the ratio of the total area of ​​the multiple vent holes 1401 to the area of ​​the liquid blocking element 140 located in the atomizing channel 1301 is 80% to 90%. If the total area of ​​the vent holes 1401 is too small, it will affect the airflow efficiency of the atomizing channel 1301; if the total area of ​​the vent holes 1401 is too large, it will affect the blocking effect of the atomizing matrix.

[0040] In some embodiments, the ratio of the total area of ​​the vent 1401 to the partial area of ​​the liquid blocking element 140 located within the atomizing channel 1301 can be 80%, 82%, 85%, 87.5%, 90%, or any value between the above ratios.

[0041] In some embodiments, the total area of ​​the vent holes 1401 is greater than 0.75 mm. 2 Specifically, the total area of ​​the vent holes 1401 is larger than the area of ​​a circle with a diameter of 1mm to ensure breathability.

[0042] In some embodiments, the number of vent holes 1401 is multiple, and the multiple vent holes 1401 are evenly distributed, forming a circular outline in the array of vent holes 1401. In some other embodiments, the shape of the array of vent holes 1401 may also be square, elliptical, polygonal, or other shapes.

[0043] In some embodiments, the liquid blocking component 140 is made of corrosion-resistant plastic, composite material, metal, or metal alloy. Specifically, the liquid blocking component 140 can be made of metal alloys such as stainless steel and titanium alloy, plastics such as polyetheretherketone and polyphenylsulfone, or ceramic materials such as alumina ceramic and zirconium oxide ceramic.

[0044] In some other embodiments, the liquid blocking element 140 can also be a porous hydrophobic membrane or a breathable membrane, which can be made of hydrophobic materials (such as polytetrafluoroethylene PTFE, polyvinylidene fluoride PVDF, polypropylene PP) to form a porous membrane. Because the material is hydrophobic, the liquid cannot wet the membrane surface, and when the surface tension of the liquid is greater than the gas osmotic pressure, the liquid is blocked outside the membrane; while gas molecules can diffuse freely through the pores.

[0045] In some other embodiments, the liquid blocking element 140 may also be a porous metal (such as stainless steel, bronze) or ceramic (such as alumina, silicon carbide) filter element manufactured by powder metallurgy or ceramic sintering processes. Liquids cannot pass through the pores due to surface tension or pore size limitations, while gas molecules can flow through the pores.

[0046] In some embodiments, the liquid blocking member 140 includes a liquid blocking portion 141, at least a portion of which is formed by at least one narrow side between adjacent vent holes 1401.

[0047] In some embodiments, the liquid blocking part 141 is located inside the atomization channel 1301. When the atomization matrix leaks along the atomization channel 1301, it can be blocked by the liquid blocking part 141, so that the atomization matrix cannot leak to the outside of the atomizer 10.

[0048] In some embodiments, such as Figure 2 , Figure 4 and Figure 7As shown, the atomizer 10 also includes a first seal 150, which is configured to provide a seal around the liquid reservoir 120. The first seal 150 is provided with an air guide hole 1501. The atomization channel 1301 includes an air passage inside the air guide hole 1501. The liquid blocking member 140 includes a fixing part 142, which is fixedly connected to the first seal 150. The liquid blocking part 141 is disposed inside the air guide hole 1501.

[0049] In some implementations, the ratio of the total area of ​​the vent 1401 to the cross-sectional area of ​​the air guide 1501 is 80% to 90% to ensure the flow efficiency of the airflow in the air guide 1501 while blocking the liquid.

[0050] In some embodiments, the outline shape of the liquid blocking element 140 can be circular, while in other embodiments, the outline shape of the liquid blocking element 140 can also be triangular, elliptical, polygonal, or other shapes.

[0051] In some embodiments, the liquid-blocking portion 141 is located in the middle of the liquid-blocking member 140, and the fixing portion 142 is disposed around the liquid-blocking portion 141. The outline shape formed by the liquid-blocking portion 141 may be the same as the outline shape of the liquid-blocking member 140, and the outline shape formed by the liquid-blocking portion 141 may be circular, elliptical, square, or other shapes. In some other embodiments, the outline shape formed by the liquid-blocking portion 141 may also be different from the outline shape of the liquid-blocking member 140. For example, the outline shape formed by the liquid-blocking portion 141 may be circular, and the outline shape of the liquid-blocking member 140 may be square.

[0052] In some embodiments, the air guide hole 1501 may be cylindrical, and the fixing part 142 is embedded in the side wall of the air guide hole 1501. The shape of the air guide hole 1501 may be adapted to the contour shape formed by the liquid blocking part 141. In some other embodiments, the shape of the air guide hole 1501 may also be prismatic, frustum-shaped, or truncated pyramidal.

[0053] In some embodiments, the first seal 150 is made of elastic silicone or rubber.

[0054] In some embodiments, the fixing part 142 is embedded in the first seal 150, and the fixing part 142 can be embedded into the first seal 150 by insert injection molding.

[0055] In some other embodiments, the fixing part 142 can be fixedly connected to the first sealing member 150 by means of snap-fit, adhesive, or other methods. The fixing part 142 can also be fixedly connected to the end of the atomizing core 130 away from the nozzle 110.

[0056] In some other embodiments, there may be multiple fixing portions 142, and the multiple fixing portions 142 are arranged at intervals along the circumference of the liquid blocking member 140. The fixing portions 142 may be pointed to insert into the side wall of the air guide hole 1501 and be fixedly connected to the first sealing member 150.

[0057] In some embodiments, the first sealing member 150 has a base 160 at the end away from the mouthpiece 110. The base 160 has an air inlet 1601, which is connected to the air guide hole 1501. External air can enter the atomizer 10 through the air inlet 1601 and enter the atomizing core 130 through the air guide hole 1501. The aerosol formed by the heating of the atomizing matrix by the atomizing core 130 can mix with air in the atomizing channel 1301 and be discharged from the mouthpiece 110. The vent hole 1401 provided on the liquid blocking part 141 allows external air to enter the atomizing channel 1301, while preventing liquids such as atomizing matrix or condensate in the atomizing channel 1301 from leaking through the air guide hole 1501, effectively preventing the atomizing matrix or other liquids from leaking to the outside of the atomizer 10.

[0058] In some embodiments, the projection plane of the air inlet 1601 toward the surface where the liquid blocking element 140 is located and the projection plane of the air guide 1501 toward the surface where the liquid blocking element 140 is located do not coincide. Liquids such as atomizing matrix that slide down from the air guide 1501 will not fall directly onto the air inlet 1601, further preventing the atomizing matrix from leaking to the outside of the atomizer 10.

[0059] In some embodiments, the air inlet 1601 and the vent 1401 are connected, and the projection surface of the air inlet 1601 toward the surface where the liquid blocking element 140 is located does not coincide with at least part of the vent 1401. When too much atomizing matrix accumulates on the side of the liquid blocking element 140 toward the nozzle 110, the atomizing matrix may seep through the vent 1401 under pressure. Since the projection surface of the air inlet 1601 toward the surface where the liquid blocking element 140 is located does not coincide with the vent 1401, the leakage of atomizing matrix can be effectively prevented from falling directly into the air inlet 1601.

[0060] In some embodiments, the projection surface of the air inlet 1601 toward the surface where the liquid blocking element 140 is located and the vent 1401 do not overlap at all, so that the leaked atomized matrix cannot fall directly onto the air inlet 1601.

[0061] In some other embodiments, the projection surface of the air inlet 1601 toward the surface where the liquid blocking element 140 is located coincides with a portion of the vent 1401, so that the airflow entering from the air inlet 1601 can flow directly to the vent 1401, thereby improving the air intake efficiency.

[0062] In some embodiments, such as Figure 6As shown, the first sealing element 150 has a connecting groove 1506 on the side opposite to the atomizing core 130, and the air inlet 1601 is connected to the air guide hole 1501 through the connecting groove 1506. The projection surface of the air inlet 1601 in its extending direction is located in the connecting groove 1506. The air entering the atomizer 10 from the air inlet 1601 can be guided to the air guide hole 1501 by the connecting groove 1506 to ensure smooth airflow.

[0063] In some embodiments, a liquid-absorbing member 170 is provided between the first sealing member 150 and the base 160. The liquid-absorbing member 170 can be used to absorb liquids such as atomizing matrix. The projection surface of the air guide hole 1501 in its extending direction is located on the liquid-absorbing member 170. Liquids such as atomizing matrix that slide down from the air guide hole 1501 can fall directly onto the liquid-absorbing member 170 and be absorbed by the liquid-absorbing member 170.

[0064] In some embodiments, such as Figure 7 As shown, the first sealing element 150 is provided with an installation groove 1502, the atomizing core 130 is provided with an atomizing tube 131, the air guide hole 1501 is provided on the bottom wall of the installation groove 1502, the atomizing tube 131 is inserted into the installation groove 1502, and the air guide hole 1501 and the atomizing tube 131 are connected.

[0065] In some embodiments, the side wall of the mounting groove 1502 is provided with an air guide groove 1503, which connects the liquid storage chamber 120 and the air guide hole 1501. During the operation of the atomizer 10, the atomizing matrix in the liquid storage chamber 120 is gradually consumed, causing the air pressure in the liquid storage chamber 120 to decrease. External air can enter the liquid storage chamber 120 through the air guide hole 1501 and the air guide groove 1503 to balance the air pressure in the liquid storage chamber 120.

[0066] In some embodiments, such as Figure 3 As shown, the atomizing core 130 includes a heating element 132 and a liquid guiding element 133. The liquid guiding element 133 is wrapped around the heating element 132, and the heating element 132 and the liquid guiding element 133 are installed inside the atomizing tube 131. The atomizing matrix in the liquid storage chamber 120 can enter the atomizing core 130 through the holes opened on the atomizing tube 131, and is guided to the heating element 132 by the liquid guiding element 133. The atomizing matrix is ​​heated and atomized by the heating element 132 to form an aerosol.

[0067] In some embodiments, the liquid guide 133 may be cylindrical in shape, the atomization channel 1301 may include an air passage formed by the liquid guide 133, the heating element 132 is disposed in the atomization channel 1301, and the aerosol formed by the heating element 132 heating the atomization matrix may be discharged from the nozzle 110 along the atomization channel 1301.

[0068] In some embodiments, the liquid guiding component 133 can be oil-guiding cotton; the heating component 132 can be made of heating wire or heating mesh made of materials such as iron-chromium-aluminum, stainless steel, or nickel-chromium alloy.

[0069] In some embodiments, the base 160 is provided with an electrode 161, and the bottom wall of the mounting groove 1502 is provided with a conductive hole 1504. The pins of the heating element 132 are inserted into the conductive hole 1504 and electrically connected to the electrode 161. The power supply assembly 20 can supply power to the heating element 132 through the electrode 161. The electrode 161 is located on the side of the first sealing member 150 away from the liquid storage chamber 120. The atomizing matrix leaking from the liquid storage chamber 120 and the atomizing core 130 can be blocked by the liquid blocking member 140, which can effectively prevent the atomizing matrix from contacting the electrode 161, avoid the risk of short circuit, and improve the reliability of the atomizer 10.

[0070] In some embodiments, the electrode 161 may be an electrode nail, and the material of the electrode 161 may be a metal or metal alloy material with conductive properties such as copper, aluminum, nickel, stainless steel, or nickel alloy.

[0071] In some embodiments, such as Figures 5 to 7 As shown, there are two conductive holes 1504, which are respectively provided on both sides of the air vent 1501. The liquid blocking member 140 may also be provided with through holes 1402 on both sides of the liquid blocking part 141. The through holes 1402 are opened in the fixing part 142. The position of the through holes 1402 corresponds to the position of the conductive holes 1504, so that when the liquid blocking member 140 is embedded in the first sealing member 150, the liquid blocking member 140 will not block the conductive holes 1504. The pins of the heating member 132 can pass through the conductive holes 1504 and the through holes 1402.

[0072] In some embodiments, the pins of the heating element 132 are embedded in the conductive hole 1504, and the sidewall of the conductive hole 1504 can fit with the pins of the heating element 132, so that the atomizing matrix cannot leak from the gap between the pins of the heating element 132 and the sidewall of the conductive hole 1504.

[0073] In some embodiments, the conductive hole 1504 is provided with a groove 1505 at one end near the atomizing tube 131, and the air guide groove 1503 is connected to the atomizing tube 131 through the groove 1505.

[0074] In some embodiments, the conductive hole 1504 is located on the bottom wall of the mounting groove 1502, the groove 1505 is arranged around the conductive hole 1504, the groove wall of the groove 1505 is inclined, and one end of the air guide groove 1503 extends along the side wall of the mounting groove 1502 to the groove 1505. One end of the atomizing tube 131 can abut against the bottom wall of the mounting groove 1502. The arrangement of the groove 1505 can prevent the air guide groove 1503 and the air guide hole 1501 from being completely separated by the side wall of the atomizing tube 131, so that the air guide groove 1503 can bypass the side wall of the atomizing tube 131 through the groove 1505 and communicate with the internal space of the atomizing tube 131, so that external air can enter the atomizing tube 131 through the air guide hole 1501, and enter the liquid storage chamber 120 through the groove 1505 and the air guide groove 1503.

[0075] In some embodiments, such as Figure 3 As shown, the mouthpiece 110 is connected to a first air guide tube 111 on the side facing the atomizing core 130, and the atomizing tube 131 is connected to a second air guide tube 134 at the end near the mouthpiece 110. The first air guide tube 111 and the second air guide tube 134 are connected, and the aerosol generated by the atomizing core 130 can be discharged from the mouthpiece 110 through the second air guide tube 134 and the first air guide tube 111.

[0076] In some embodiments, the atomizing channel 1301 includes an air passage inside the air guide hole 1501, an air passage formed by the liquid guide member 133, an air passage inside the second air guide tube 134, and an air passage inside the first air guide tube 111. The liquid blocking member 140 is used to block the atomizing matrix that leaks along the atomizing channel 1301.

[0077] In some embodiments, a first air guide tube 111 is inserted into a liquid storage tank 120, and a second air guide tube 134 is inserted into the first air guide tube 111. A second sealing member 180 is sealingly connected between the first air guide tube 111 and the second air guide tube 134. The side wall of the second air guide tube 134 is provided with a protrusion for supporting the second sealing member 180, so that the second sealing member 180 can be inserted into the first air guide tube 111 during assembly, and the second sealing member 180 is press-fitted with the inner wall of the first air guide tube 111 and the outer wall of the second air guide tube 134.

[0078] In some embodiments, the cross-sectional area of ​​the second air guide tube 134 is smaller than the cross-sectional area of ​​the atomizing tube 131. The second air guide tube 134 and the atomizing tube 131 can be an integral structure formed by injection molding.

[0079] In some embodiments, the first air guide tube 111, the nozzle 110, and the liquid storage tank 120 can be an injection-molded integral structure, which makes the structure of the atomizer 10 simpler, reduces the formation of connection gaps, and helps to improve the sealing performance.

[0080] This application embodiment also provides an atomizing device, which includes the atomizer 10 of the above embodiment, and the atomizing device also includes a power supply component 20, which is electrically connected to the atomizer 10 to supply power to the atomizer 10.
