Description

Technical Field

[0001] The present invention relates to the field of electronic atomization, and in particular to an electronic atomization device and an atomizer thereof. Background Art

[0002] An electronic atomization device generally includes a liquid storage space, a porous heating element, a seal, and an air flow channel. The seal is used to prevent the liquid in the liquid storage space from flowing to places outside the heating element. During heating and atomization, the liquid in the liquid storage space decreases, the internal gas space increases, the air pressure decreases, and the resistance of the liquid to the heating element increases, which can easily lead to insufficient liquid supply and dry burning. In order to solve this problem, the relevant technology chooses to add a ventilation structure that connects the ambient gas and the liquid storage space. Driven by the pressure difference, the ambient gas replenishes the gas to the liquid storage space through the ventilation structure to balance the air pressure. At present, the ventilation port is generally located on the bottom wall or the surrounding wall of the liquid storage space, but bubbles easily adhere to the wall surface around the ventilation port, resulting in bubble jamming and hindering ventilation.

[0038] Figure 1 and Figure 2 The electronic atomization device in some embodiments of the present invention is shown. The electronic atomization device may be a hand-held rod-shaped structure for users to inhale aerosols. As shown in the figure, the electronic atomization device may include an atomizer 1 and a power supply device 2 that cooperates with the atomizer 1. The atomizer 1 can be used to store and heat atomize liquid aerosols such as liquid medicine to generate a matrix, and to guide the aerosol out. The power supply device 2 can be used to power the atomizer 1. In some embodiments, the atomizer 1 and the power supply device 2 may both be roughly elliptical cylindrical, and the two are mechanically and electrically connected together along the axial direction. In some embodiments, the atomizer 1 and the power supply device 2 can be detachably connected together by magnetic attraction. It can be understood that the atomizer 1 and the power supply device 2 are not limited to being elliptical cylindrical, and they can also be cylindrical with a circular, runway-shaped or irregular cross-section, or non-columnar.

[0039] Figures 3 to 6The nebulizer 1 in some embodiments of the present invention is shown. The nebulizer 1 may include an atomizing body 10 and a housing 20 sleeved on the atomizing body 10 along a longitudinal axis X. The atomizing body 10 and the housing 20 together define a liquid storage space for storing a liquid aerosol-generating substrate. The atomizing body 10 is used to heat the liquid aerosol-generating substrate in the liquid storage space to generate an aerosol. The housing 20 is used to protect the atomizing body 10 and to guide the aerosol-air mixture. In some embodiments, the liquid storage space may include a liquid storage tank 214 formed between the outer wall surface of the atomizing body 10 and the inner wall surface of the housing 20, and a liquid lowering channel formed in the atomizing body 10. The liquid storage tank 214 is used to store the liquid aerosol-generating substrate, and the liquid lowering channel is used to transport the liquid in the liquid storage tank 214 to the atomizing assembly 13.

[0040] In some embodiments, the housing 20 may include a flat shell 21 having an opening 212 at one end and an air outlet 210 at the other end, and an air guide duct 22 having one end connected to the air outlet 210 and the other end extending toward the opening 212 of the housing 21. The end of the air guide duct 22 is inserted into the atomizing body 10 to guide the mist generated when the atomizing body 10 is working. An annular liquid storage tank 214 is defined between the inner wall surface of the housing 21 and the outer wall surface of the air guide duct 22. The opening 212 allows the atomizing body 10 to be inserted into the housing 20. A snap-fit ​​structure 216 can also be provided on the inner side of the open end of the housing 21 to snap with the atomizing body 10 inserted into the open end of the housing 21.

[0041] See also Figures 7 to 9 , the atomizing body 10 may be symmetrical on the front and rear sides, and on the left and right sides in some embodiments, to facilitate molding and subsequent assembly. In some embodiments, the atomizing body 10 may include a lower seat 11, an upper seat 12 snap-connected to the lower seat 11, an atomizing assembly 13 sandwiched between the lower seat 11 and the upper seat 12, and a pair of electrodes 14 that are spaced apart and electrically connected to the atomizing assembly 13 respectively. It can be understood that the atomizing body 10 is not limited to a symmetrical structure, and an asymmetric structure may also be applicable. In some embodiments, the atomizing assembly 13 may be arranged horizontally, that is, it is arranged in a plane that is perpendicular to the longitudinal axis X of the atomizing body 10.

[0042] In some embodiments, the lower base 11 can be integrally formed of a hard plastic material, and is preferably symmetrical on the front and rear sides, and on the left and right sides, for ease of manufacturing and subsequent assembly. In some embodiments, the lower base 11 may include a roughly elliptical base 111, a first support arm 112 erected at the first end of the top surface of the base 111 in the direction of the long axis, and a second support arm 113 erected at the second end of the top surface of the base 111. The first support arm 112 and the second support arm 113 together support the atomizer assembly 13 from the bottom side of the atomizer assembly 13, forming a lower side support portion (second support portion) of the atomizer assembly 13. There is a gap between the first support arm 112 and the second support arm 113 so that when the atomizer assembly 13 is horizontally mounted on the first support arm 112 and the second support arm 113, an atomizer chamber 110 is formed on the bottom side of the atomizer assembly 13. The atomizer chamber 110 is used to allow the aerosol atomized by the atomizer assembly 13 to mix with the air inhaled from the outside and be carried away by the airflow.

[0043] In some embodiments, the base 111 may include an air inlet passage 1110 located in the middle and extending vertically therethrough, and a pair of mounting holes 1112 extending vertically therethrough, wherein the pair of mounting holes 1112 are used to respectively allow the lower ends of the pair of electrodes 14 to pass through.

[0044] For example Figure 7 As shown, in some embodiments, the first support arm 112 may include a first support portion 1121 and a first stop portion 1122 extending upward from a top surface of the first support portion 1121 away from the second support arm 113. The first support portion 1121 is used to support one end of the atomizer assembly 13, and the first stop portion 1122 is formed with a first locking hole 1120 for locking with the upper base 12.

[0045] In some embodiments, the second support arm 113 may include a second support portion 1131 and a second retaining portion 1132 extending upward from a top surface of the second support portion 1131 away from the first support arm 112. The second support portion 1131 is used to support the other end of the atomizer assembly 13, and the second retaining portion 1132 is formed with a first latching hole 1130 for latching with the upper base 12.

[0046] In some embodiments, the first support portion 1121 and the second support portion 1131 may respectively include a pair of first ventilation grooves 1123 extending laterally formed on the top surface and a pair of second ventilation grooves 1125 extending longitudinally formed on the inner side surface. The pair of first ventilation grooves 1123 are respectively connected to the pair of second ventilation grooves 1125. One end of each first ventilation groove 1123 away from the atomization chamber 110 is exposed outside the atomization assembly 13 and is connected to the lower end of the corresponding third ventilation groove 1225 of the upper seat body 12.

[0047] In some embodiments, the upper body 12 may be integrally formed of a hard plastic material, and may be symmetrical in front and back, and symmetrical in left and right. In some embodiments, the upper body 12 may include a main body 121 and a pressing portion 122 disposed below the main body 121.

[0048] In some embodiments, the main body 121 may include a pair of lower liquid ports 1210 and an air outlet channel 1212. The air outlet channel 1212 may be located in the middle of the top of the main body 121 and arranged longitudinally. The pair of lower liquid ports 1210 may be respectively arranged on two opposite sides of the air outlet channel 1212 and arranged longitudinally. In some embodiments, the main body 121 may also include a collecting portion 1214. The collecting portion 1214 is located below the pair of lower liquid ports 1210 and is respectively connected to the pair of lower liquid ports 1210, so that the liquid aerosol generating matrix in the liquid storage tank 214 can be discharged as shown in FIG. Figure 3 The liquid flows into the collecting portion 1214 in the direction indicated by the arrow N. The gas outlet channel 1212 is used to communicate with the lower end of the gas guide pipe 22 of the housing 20. The collecting portion 1214 and the pair of lower liquid ports 1210 together form the lower liquid channel.

[0049] In some embodiments, the main body 121 may further include a pair of air guide grooves 1216 (eg, Figure 4 The pair of air guide grooves 1216 are formed on the outer wall surfaces of the two opposite sides of the main body 121 and extend from top to bottom. The pair of air guide grooves 1216 and the outer shell 21 define an air guide channel ( Figure 4 The arrow M in the middle shows the gas flow direction).

[0050] In some embodiments, the pressing portion 122 may include an annular supporting portion 1220, which presses against the upper side of the edge of the atomizer assembly 13, forming the upper side supporting portion (first supporting portion) of the atomizer assembly 13. Together with the lower side supporting portion (first supporting portion 1121 and second supporting portion 1131) of the atomizer assembly 13 on the lower seat, the atomizer assembly 13 is clamped and fixed. The middle portion of the supporting portion 1220 includes a lower liquid port 1222 that runs vertically through the main body 121 and directly faces the liquid suction surface of the atomizer assembly 13. The lower liquid port 1222 is connected to the collecting portion 1214 of the main body 121 and is located directly below the collecting portion 1214 to allow the liquid aerosol-generating matrix in the collecting portion 1214 to flow to the liquid suction surface of the atomizer assembly 13. In some embodiments, the lower liquid port 1222 may be rectangular and its size is adapted to the liquid suction surface of the atomizer assembly 13.

[0051] In some embodiments, the pressing portion 122 may include an inner frame 1224 formed on the bottom surface of the supporting portion 1220 and surrounding the lower liquid port 1222, and an outer frame 1226 formed on the periphery of the bottom surface of the supporting portion 1220. The inner frame 1224 is used to laterally support the inner side of the seal 132 of the atomizing assembly 13, and the outer frame 1226 is used to laterally support the outer side of the seal 132.

[0052] In some embodiments, the abutting portion 1220 may include a pair of ventilation holes 1221 extending vertically therethrough. The pair of ventilation holes 1221 are aligned with the seal 132 of the atomizing assembly 13 and connect the lower side of the abutting portion 1220 to the collecting portion 1214 located on the upper side of the abutting portion 1220. This allows ventilation into the liquid storage space when the liquid pressure in the liquid storage space is too low, thereby achieving gas-liquid balance within the liquid storage space. The upper surface of the abutting portion 1220 constitutes a bottom wall of the liquid storage space, and in some embodiments, a pair of ventilation tubes 1223 are provided thereon, corresponding to the pair of ventilation holes 1221. The pair of ventilation tubes 1223 are respectively connected to the pair of ventilation holes 1221, and the axes of the ventilation tubes 1223 are perpendicular to the liquid absorption surface of the heating element 131, so that the ventilation port 1229 at the end of the ventilation tube 1223 protrudes a distance from the upper surface of the supporting portion 1220 (i.e., a bottom wall surface of the liquid storage space), thereby preventing or reducing bubbles from adhering to the upper surface of the supporting portion 1220 and the liquid absorption surface of the heating element 131 during the ventilation process. In some embodiments, the vertical distance from the ventilation port 1229 to the liquid absorption surface of the heating element 131 is preferably greater than the vertical distance from the ventilation port to the upper surface of the supporting portion 1220. In some embodiments, the upper surface of the supporting portion 1220 can be a horizontally arranged flat surface. It is understandable that the ventilation tube 1223 is not limited to being set on the surface of the collecting portion 1214. In some embodiments, as the position of the ventilation hole 1221 changes, it can also be set on the inner wall surface of the lower liquid port 1210 or the liquid storage tank 214.

[0053] like Figure 8 As shown, in some embodiments, the ventilation tube 1223 can be integrally formed with the abutment portion 1220. In some embodiments, the central through hole of the ventilation tube 1223 employs a stepped hole design, with the diameter of the first hole section on the side closer to the abutment portion 1220 being larger than the diameter of the second hole section on the side farther from the abutment portion 1220. In some embodiments, the diameter of the first hole section is 0.5-1 mm, and the diameter of the second hole section is 0.2-0.6 mm. In some embodiments, the length of the ventilation tube 1223 is 0.8-1.5 mm.

[0054] like Figure 9As shown, in some embodiments, a pair of longitudinally extending third ventilation grooves 1225 may be formed on the inner wall surface of the outer frame 1226 near each ventilation hole 1221, and a fourth ventilation groove 1227 is correspondingly formed on the lower surface of the abutting portion 1220 to connect the ventilation hole 1221 with the third ventilation groove 1225. In this way, the second ventilation groove 1125, the first ventilation groove 1123, the third ventilation groove 1225, the fourth ventilation groove 1227, the ventilation hole 1221, and the ventilation tube 1223 are sequentially connected to form the ventilation channel of the atomizer 1. It can be understood that although the ventilation channels of the atomizer 1 shown in the figure include four distributed near the four corners of the atomizing assembly 13, they are not limited to four. Fewer than four or more than four are also applicable, and can be increased or decreased according to specific circumstances.

[0055] The outer frame 1226 extends downwardly from the lower end surfaces of the two opposite side walls close to the pair of ventilation holes 1221 to respectively embed into the upper surfaces of the first support portion 1121 and the second support portion 1131 of the lower seat body 11. The upper surfaces of the first support portion 1121 and the second support portion 1131 are respectively formed with a pair of arc-shaped embedding grooves 1126 for the ends of the embedding portions 1228 to embed into, and the two ends of each embedding groove 1126 are respectively connected to the corresponding pair of first ventilation grooves 1123 (as shown in FIG. Figure 7 shown).

[0056] like Figure 10 As shown, in some embodiments, the atomization assembly 13 may include a sheet-like heating element 131 and a soft sealing member 132 coupled to the edge of the heating element 131. The heating element 131 may include a liquid absorption surface located on the upper side 133 and an atomization surface located on the lower side 134 and opposite to the liquid absorption surface. When the sealing member 132 is coupled to the edge of the heating element 131, both the liquid absorption surface and the atomization surface are exposed.

[0057] In some embodiments, the heating element 131 may include a sheet-like substrate 1311 and a heating layer 1312 formed on the bottom surface of the substrate 1311. The substrate 1311 may be glass or dense ceramic with a micropore array, or a sheet-like porous ceramic.

[0058] In some embodiments, the substrate 1311 may include a flat upper surface and a lower surface that are parallel to each other, wherein the middle area of ​​the upper surface forms a liquid absorption surface, and the middle area of ​​the lower surface forms an atomization surface. The thickness of the substrate 1311 may be 0.1 to 10 mm in some embodiments. In some cases, the thickness of the substrate 1311 may be 0.1 to 1 mm. The porosity range of the substrate 1311 may be 0.2 to 0.8 in some embodiments, and the surface tension range of the aerosol generating matrix adapted thereto may be 38 to 65 mN / m in some embodiments. It is understandable that the heating element 131 is not limited to being a rectangular sheet, and in some embodiments it may also be in other shapes such as a square sheet, a circular sheet, an elliptical sheet, a racetrack-shaped sheet, or a special-shaped sheet.

[0059] In some embodiments, the soft seal 132 may be in the shape of a rectangular ring so that the upper liquid absorption surface and the lower atomization surface of the heating element 131 are exposed. In some embodiments, the soft seal 132 may be wrapped around the periphery of the heating element 131, and a groove 1320 is formed on the inner wall surface for the edge of the heating element 131 to be embedded, so that the upper side, lower side and outer side of the edge of the heating element 131 are all covered by the seal 132, which can prevent liquid leakage on the one hand and protect the heating element 131 from being crushed on the other hand. In some embodiments, the soft seal 132 also includes a slot 1322 formed on a frame so that the heating element 131 can be inserted into the seal 132. In some embodiments, the soft seal 132 can also be integrally injection molded with the heating element 131. In other embodiments, the seal 132 can also be formed by splicing two or more structures.

[0060] In some embodiments, the atomizing body 10 further includes a reinforcement 15, which may include a rectangular annular body. In some embodiments, a material that is not easily broken and can withstand greater force may be used, which may be a metal sheet, a dense ceramic, or a hard plastic, preferably a metal sheet, such as a steel sheet SUS-316L (food grade), with a thickness range of 0.1-0.5 mm (preferably, the thinner the better as long as the strength meets the requirements). The two ends of the annular body of the reinforcement 15 are supported by the first support arm 112 and the second support arm 113 respectively to support the atomizing assembly 13. The four frames of the annular body of the reinforcement 15 are respectively supported under the four frames of the seal 132 of the atomizing assembly 13, so that the heating element 131 of the atomizing assembly 13 is evenly stressed all around to avoid breakage due to excessive stress. When the soft seal 132 of the atomizing assembly 13 is evenly stressed, the sealing is better. The central through hole 150 of the annular body of the reinforcement 15 forms an opening that exposes the atomizing surface of the heating element 131.

[0061] In some embodiments, the soft seal 132 may include a pair of arc-shaped first limiting protrusions 1321, each formed on the outer wall surfaces of two opposing sides of the seal 132. Accordingly, a pair of arc-shaped second limiting protrusions are provided on the outer sides of two opposing sides of the reinforcement 15. The inner sides of the two opposing sides of the reinforcement 15 are each concave to form an arc-shaped avoidance groove 152, which provides clearance for the installation of the pair of electrodes 14.

[0062] In some embodiments, the atomizing body 10 may further include a sealing sleeve 16, which is sleeved on the upper portion of the upper body 12 to achieve a liquid-tight seal between the upper body 12 and the inner wall of the housing 20. In some embodiments, a pair of lower liquid holes 160 and an air hole 162 may be formed on the top wall of the sealing sleeve 16. The pair of lower liquid holes 160 are respectively connected to the pair of lower liquid ports 1210 of the upper body 12, and the air hole 162 is respectively connected to the air outlet channel 1212 of the upper body 12.

[0063] It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several variations and improvements can be made, all of which fall within the scope of protection of the present invention.
