[0051] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0052] It should be understood that terms such as "front," "rear," "left," "right," "upper," "lower," "first," and "second" are merely for the convenience of describing the technical solutions of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore should not be construed as limitations on the present invention. It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0053] Figure 1 and Figure 2 An electronic atomizing device according to a first embodiment of the present invention is shown. This electronic atomizing device can be applied to the atomization of liquid media such as e-liquids and drugs. It may include an atomizer 100 and a battery device 2 mechanically and electrically connected to the atomizer 100. The atomizer 100 is used to heat and atomize the liquid medium, and the battery device 2 is used to supply power to the atomizer 100. Preferably, the atomizer 100 and the battery device 2 are detachably connected.

[0054] See also Figure 3 and Figure 4In some embodiments, the atomizer 100 may include a cylindrical outer shell 110, a base 120, an atomizing assembly 130, a cylindrical liquid storage shell 140, a gas-liquid balance element 150, and a liquid guiding element 160. The base 120 is disposed on an open end of the outer shell 110. The atomizing assembly 130 is disposed on the base 120 and located inside the outer shell 110. One end of the liquid storage shell 140 is sleeved above the atomizing assembly 130 and located within the outer shell 110. The gas-liquid balance element 150 is disposed above the atomizing assembly 130 and located within the liquid storage shell 140. The liquid guiding element 160 passes through the gas-liquid balance element 150 and connects the atomizing assembly 130 to the liquid storage cavity 141 of the liquid storage shell 140.

[0055] In some embodiments, the cylindrical outer casing 110 may include an open end 111 at the bottom, a mouthpiece end 112 opposite to the open end 111, and a cylindrical sidewall 113 connecting the open end 111 and the mouthpiece end 112. The open end 111 is combined with the base 120, and the mouthpiece end 112 has an air outlet 1120 for the user to inhale the mist. The cylindrical sidewall 113 encloses a centrally located receiving cavity 1130 for housing components such as the atomizing assembly 130 and the liquid storage shell 140. An airflow duct 1131 and a window 1132 connecting the receiving cavity 1130 to the outside are also formed in the sidewall 113. The airflow duct 1131 extends from the open end 111 to the air outlet 1120 of the mouthpiece end 112, and the window 1132 exposes at least partially the liquid storage shell 140 to the outside.

[0056] In some embodiments, the base 120 may include an atomizing chamber 121 located below the atomizing assembly 130 and an air inlet 122 connected to the atomizing chamber 121. The atomizing chamber 121 is connected to an airflow duct 1131 on the outer casing 110, and the air inlet 122 is connected to the external environment. The air inlet 122, the atomizing chamber 121, the airflow duct 1131, and the air outlet 1120 are sequentially connected to form the mist channel of the atomizer 100 (e.g., ...). Figure 3 (As indicated by the arrow).

[0057] See also Figure 5In some embodiments, the atomizing component 130 can be mounted on a base 120. It may include a porous ceramic substrate 131 mounted on the base 120 and a heating element 132 mounted on the porous ceramic substrate 131. The porous ceramic substrate 131 includes a liquid-absorbing surface at the top and an atomizing surface at the bottom. The liquid-absorbing surface is connected to the lower end of a liquid-guiding element 160, and the atomizing surface is exposed in the atomizing chamber 121. The heating element 132 is mounted on the atomizing surface. Liquid in the storage chamber 141 is transferred to the liquid-absorbing surface via the liquid-guiding element 160, enters the porous ceramic substrate 131, and is then atomized by heating on the atomizing surface. The mist mixes with air in the atomizing chamber 121 and is then carried out. The atomizing component 130 is not limited to the form shown in the figure; other forms conventional in the industry can also be applied.

[0058] The liquid storage shell 140 may be cylindrical, including a bottom wall 142 and a cylindrical side wall 143 connected at one end to the periphery of the bottom wall 142, with an opening formed at the other end of the side wall 143. This opening is fitted onto the atomizing assembly 130. An air inlet 1430 is formed on the side wall 143, which corresponds to the gas-liquid balance element 150.

[0059] See also Figures 6 to 8 In some embodiments, the gas-liquid balance element 150 may be cylindrical, axially inserted into the liquid storage shell 140, with its outer wall surface tightly fitted against the inner wall surface of the side wall 143 of the liquid storage shell 140. That is, the liquid storage shell 140 has a cavity forming a housing for the gas-liquid balance element 150, and this cavity is connected to the liquid storage cavity 141, thereby connecting the gas-liquid balance element 150 to the liquid storage cavity 141. A gap exists between the gas-liquid balance element 150 and the bottom wall 142 of the liquid storage shell 140, forming the liquid storage cavity 141 of the liquid storage shell 140. The gas-liquid balance element 150 is disposed between the liquid storage cavity 141 and the atomizing assembly 130, and is connected to the air inlet 1430 on the liquid storage shell 140 to replenish the liquid storage cavity 141 with gas (e.g., air from the atomizing assembly 130). Figure 4 (As indicated by the arrow), it also has the function of storing liquid.

[0060] In some embodiments, the gas-liquid balance element 150 may include a central shaft 156 and a set of first fins 151 arranged in parallel and spaced along the axial direction and a set of second fins 152 arranged in parallel and spaced along the axial direction, with the first fins 151 close to the liquid storage chamber 141 and the second fins 152 far away from the liquid storage chamber 141.

[0061] In some embodiments, the gas-liquid balance element 150 may further include a first isolation portion 157 located above the central shaft 156, a second isolation portion 158 located in the middle of the central shaft 156, and a third isolation portion 159 located below the central shaft 156. A first fin 151 is disposed between the first isolation portion 157 and the second isolation portion 158, and a second fin 152 is disposed between the second isolation portion 158 and the third isolation portion 159. The thicknesses of the first isolation portion 157, the second isolation portion 158, and the third isolation portion 159 are all much greater than those of the first fin 151 and the second fin 152. In some embodiments, the gas-liquid balance element 150 may further include a fourth isolation portion 155 located below the third isolation portion 159, with a gap between the fourth isolation portion 155 and the third isolation portion 159. The top surface of the first isolation portion 157 is exposed in the liquid storage cavity 141.

[0062] The central shaft 156 has a central through-hole 1560 for the liquid guiding element 160 to pass through. A first liquid storage groove 1510 penetrating the outer circumferential surface is formed between adjacent first fins 151, and a second liquid storage groove 1520 penetrating the outer circumferential surface is formed between adjacent second fins 152. The thickness of the first fins 151 and the second fins 152, and the width of the first liquid storage groove 1510 and the second liquid storage groove 1520 are small enough to exert a capillary force on the liquid medium to achieve the liquid storage function. Furthermore, the width of the first liquid storage tank 1510 is smaller than that of the second liquid storage tank 1520, which makes the capillary force of the first liquid storage tank 1510 stronger. The purpose of this arrangement is that the liquid flowing out through the return gas tank 153 will preferentially enter the first liquid storage tank 1510. Only after the first liquid storage tank 1510 is full of liquid will the second liquid storage tank 1520, which is far away from the liquid storage chamber 141, take the lead in absorbing liquid. That is, the liquid is not evenly distributed on the entire gas-liquid balance element 150 at the beginning, which can reduce the probability of leakage.

[0063] In some embodiments, the thickness of the first fin 151 and the second fin 152, and the width of the first liquid storage tank 1510 are between 0.05 and 0.2 mm, preferably between 0.09 and 0.15 mm, and the width of the second liquid storage tank 1520 is approximately 0.17 mm. In some embodiments, the gas-liquid balance element 150 may also include a narrower return gas groove 153 and a wider surface tension isolation groove 154, which are respectively disposed on opposite sides of the gas-liquid balance element 150, and preferably at a 180-degree angle. In some embodiments, the width of the return gas groove 153 may be between 0.05 and 0.2 mm, preferably between 0.09 and 0.15 mm, and it transversely cuts through the first isolation portion 157, the first fin 151, the second isolation portion 158, and most of the second fin 152 along a direction parallel to the axis of the gas-liquid balance element 150, intersecting with the corresponding first liquid storage tank 1510 and second liquid storage tank 1520. The two fins 151 near the bottom of the gas-liquid balance element 150 shown in the figure are not cut off by the return gas groove 153. The two fins 151 serve to hold the return gas groove 153, increasing the resistance to the downward flow of liquid. If the liquid is to leak out, it can only flow through the second liquid storage groove 1520 to the surface tension isolation groove 154 and then leak downward. Due to the surface tension of the second fin 152, this leakage will be more difficult, thereby reducing the probability of leakage.

[0064] The return air groove 153 extends from the lower part of the second fin 152 to the top of the gas-liquid balance element 150, communicating with the liquid storage chamber 141, so that the liquid in the liquid storage chamber 141 can flow through the return air groove 153 to the first liquid storage tank 1510 and the second liquid storage tank 1520 of each layer. The surface tension isolation groove 154 is between 1 and 2 mm in some embodiments, preferably 1.2 to 1.7 mm. It also transversely cuts the second isolation portion 158 and all the first fins 151 and second fins 152 along a direction parallel to the axis of the gas-liquid balance element 150, and also intersects with the corresponding first liquid storage tank 1510 and second liquid storage tank 1520 to achieve tension isolation of the liquid in the first liquid storage tank 1510 and the second liquid storage tank 1520.

[0065] A first air inlet groove 1590 is formed on the third isolation section 159, on the same side as the return air groove 153. The first air inlet groove 1590 is connected to the surface tension isolation groove 154 through the gap between the third isolation section 159 and the second fin 152. A second air inlet groove 1550 is provided on the fourth isolation section 155, on the same side as the surface tension isolation groove 154. The second air inlet groove 1550 is connected to the third isolation section 159 and the fourth isolation section 155 through the gap. The second air inlet groove 1550 is then connected to the air inlet 1430 on the liquid storage shell 140, thereby connecting the surface tension isolation groove 154 to the air inlet 1430 on the liquid storage shell 140, and then connecting to the external environment through the window 1132 on the outer shell 110. Preferably, the air inlet 1430 is isolated from the mist channel of the atomizer 1, so that the air replenishment channel is isolated from the mist channel, preventing the negative pressure formed in the mist channel from having an adverse effect on the air replenishment.

[0066] See also Figure 9 and Figure 10 In some embodiments, atmospheric pressure return gas can enter the liquid storage tanks 1510 of each layer through the surface tension isolation groove 154 and gather towards the return gas groove 153 (e.g., Figure 9 (As shown by the middle arrow). When negative pressure is generated in the liquid storage chamber 141, return air is drawn from the return air tank 153. Liquid in each layer of liquid storage tank 1510 enters through the surface tension isolation tank 154 and slowly flows back into the liquid storage chamber 141 through the return air tank 153 until the internal and external pressures are balanced. When the air pressure in the liquid storage chamber 141 is too high, liquid can also gradually flow downwards through the return air tank 153 into each layer of liquid storage tank 1510 (e.g., ...). Figure 10 (As indicated by the middle arrow) to balance the air pressure in the liquid storage chamber 141. This prevents liquid leakage through the atomizing component 130. In some embodiments, the liquid in the liquid storage tank 1510 can also be pushed back to the liquid storage chamber 141 via the return air tank 153 by gas to achieve pressure balance.

[0067] See also 11 and Figure 12 In some embodiments, the central shaft 156 further includes a through groove 1562 connecting the first liquid storage tank 1510 and the second liquid storage tank 1520 to the central through hole 1560, so that the first liquid storage tank 1510 and the second liquid storage tank 1520 can exchange liquid with the liquid guiding element 160. That is, when the liquid in the liquid guiding element 160 is insufficient, the liquid stored in the first liquid storage tank 1510 and the second liquid storage tank 1520 can enter the liquid guiding element 160 through the through groove 1562 (e.g., Figure 11 (As indicated by the arrow) to maintain a smooth liquid supply. Conversely, when the liquid in the liquid guiding element 160 is sufficient, but the liquid in the first liquid storage tank 1510 and the second liquid storage tank 1520 is insufficient, the liquid in the liquid guiding element 160 can enter the liquid storage tank 1510 through the channel 1562 (as shown by the arrow). Figure 12 (As indicated by the arrow) This prevents leakage caused by excessive liquid in the liquid guiding element 160, achieving liquid balance. The width of the through groove 1562 is 0.01-2 mm in some embodiments.

[0068] Figures 13 to 14 A second embodiment of the electronic atomizing device of the present invention is shown. This electronic atomizing device can be used in fields such as electronic cigarettes and medical atomization, and has the advantages of smooth liquid medium supply, high safety performance, and low leakage. The electronic atomizing device may include an atomizer 200 and a power supply device; the atomizer 200 can be used to heat and atomize the liquid medium, and the power supply device can be mechanically and electrically connected to the atomizer 200 to supply power to the atomizer 200, thereby facilitating atomization in the atomizer 200.

[0069] See also Figure 15 The atomizer 200 may include a liquid storage unit A and an atomizing unit B; the liquid storage unit A and the atomizing unit B are connected in a liquid-conducting connection. The liquid storage unit A is used to store the liquid medium and discharge the mist; the atomizing unit B can be used to heat and atomize the liquid medium.

[0070] like Figures 14 to 16 As shown, the liquid storage unit A may include a housing 210; the housing 210 may be fitted around the atomizing unit B, and its inner side may be used to form a liquid storage cavity 211 for containing the liquid medium. Specifically, a space is left between the housing 210 and the upper part of the atomizing unit B, and this space may form the liquid storage cavity 211. The inner side of the housing 210 is also provided with a mist channel 212, which may be arranged along the axial direction of the housing 210 and may be connected to the air guide of the atomizing unit B to output the mist formed by the atomizing unit B. The end of the mist channel 212 away from the atomizing unit B is provided with an air outlet, which may form a mouthpiece for the user to inhale the mist. A sealing element may be provided on the air outlet to seal the air outlet when the atomizer 210 is not in use, to prevent debris from entering the mist channel 212. A gap is provided between the mist channel 212 and the side wall of the outer casing 210 to facilitate liquid flow around the mist channel 212. The liquid storage chamber 211 may be located around the mist channel 212. An air inlet 213 is provided on the lower side wall of the outer casing 210. There may be two air inlets 213, which may be located on two opposite sides of the outer casing 210, allowing gas to enter the liquid storage chamber 211.

[0071] The atomizing unit B can be disposed within the housing 210, located at the lower part of the liquid storage chamber 211. Understandably, in some other embodiments, the atomizing unit B can also be located outside the housing 210, at the lower part of the housing 210. The atomizing unit B may include a base 220, an atomizing support 240, an atomizing assembly 230, a gas-liquid balance element 250, at least two liquid guiding elements 260, a first sealing structure 270, and an electrode assembly 290. The base 220 is for mounting the atomizing support 240 and the gas-liquid balance element 250. The housing 210 can be fitted onto the base 220. The atomizing support 240 is disposed on the base 220 and can be used to support the atomizing assembly 230. The atomizing assembly 230 can be housed within the gas-liquid balance element 250 and can be used to heat the liquid medium to form a mist that can be inhaled by the user. The gas-liquid balance element 250 is disposed between the liquid storage chamber 211 and the atomizing assembly 230. It can be sleeved around the atomizing assembly 230 and communicates with the air inlet 213, thereby connecting the liquid storage chamber 211 to the outside and balancing the gas pressure in the liquid storage chamber 211. At least two liquid guiding elements 260 can be inserted into the gas-liquid balance element 250, connecting the liquid storage chamber 211 and the atomizing assembly 230 at both ends to supply liquid medium to the atomizing assembly 230. The first sealing structure 270 can be disposed between the gas-liquid balance element 250 and the liquid storage chamber 211, sealing the gap formed between the outer ring of the gas-liquid balance element 250 and the liquid storage chamber 211. The motor assembly 290 can extend from the base 220 and be electrically connected to the atomizing assembly 230.

[0072] In some embodiments, the base 220 may include a seat 221, a positioning post 222, and an air intake channel 230. The shape and size of the seat 221 may be adapted to the shape and size of the opening end of the housing 210, and it can be used to seal the opening of the housing 210. The positioning post 222 may be disposed on the seat 221, and it can be used to cooperate with the atomizing bracket 240 for positioning. The air intake channel 230 may be axially disposed on the seat 221, and it is disposed opposite to the atomizing assembly 230, allowing gas to enter the atomizing assembly 230.

[0073] In some embodiments, the atomizing bracket 240 may include a mating portion 241 and a support portion 242 disposed on the mating portion 241; the mating portion 241 may be placed on the base 221, and its shape and size are adapted to the base 221; the support portion 242 may protrude toward the mating portion 241 and is used to support the atomizing assembly 230; the support portion 242 may be sleeved on the positioning post 222 and cooperate with the positioning post 222 for positioning.

[0074] In some embodiments, the atomizing assembly 230 may include an atomizing core 231 and a heating element 232. The atomizing core 231 may be a cotton wick, which may be placed on the atomizing support 240 and may be radially disposed in the gas-liquid balance element 250, with both ends of which may be connected to the at least two liquid guiding elements 260 for liquid guiding. The heating element 232 may be a heating wire, which may be wound around the atomizing core 231 and may be electrically connected to the electrode assembly 290 to heat the liquid medium in the atomizing core 231 to form mist.

[0075] See also Figures 15 to 17 In some embodiments, the gas-liquid balance element 250 may be cylindrical, specifically, it may be a cylindrical shape with an elliptical or rectangular cross-section, and its outer periphery may be joined to the inner wall of the outer casing 210 by an interference fit to seal the liquid storage cavity 211. The gas-liquid balance element 250 may serve as an atomizing housing, which may house the atomizing assembly 230.

[0076] In some embodiments, the gas-liquid balance element 250 may include at least two through holes 251, a liquid storage and ventilation structure 252, and an airflow channel. The at least two through holes 251 are correspondingly disposed with respect to the at least two liquid guiding elements 260, and the liquid guiding elements 260 can pass through them. In this embodiment, the at least two through holes 251 may include two through holes 251. It is understood that in some other embodiments, the at least two through holes 251 may not be limited to including two through holes. The liquid storage and ventilation structure 252 may be located around the two through holes 251, and it may be sleeved around the atomizing assembly 230. An atomizing chamber 527 may be formed on its inner side, and it can be used to connect the liquid storage chamber 211 to the outside to balance the gas pressure in the liquid storage chamber 211. The airflow channel may include an air outlet channel 253; the air outlet channel 253 communicates with the atomizing chamber 527 and is located between the two through holes 251, and it can output the mist formed after atomization by the atomizing assembly 230. The liquid storage and ventilation structure 252 can also be connected to the at least two liquid guiding elements 260 to balance the liquid supply of the liquid guiding elements 260.

[0077] In some embodiments, the liquid storage and ventilation structure 252 may include a plurality of fins 2521; the plurality of fins 2521 may be arranged parallel to each other along the axial direction. A liquid storage groove 2522 penetrating the outer peripheral surface of the liquid storage and ventilation structure 252 may be formed between each pair of adjacent fins 2521; the width of the liquid storage groove 2522 is small enough to generate capillary force on the liquid medium, so that when the liquid flows into the liquid storage groove 2522, a liquid film can be formed in the liquid storage groove 2522, and thus it can be stored in the liquid storage groove 2522 to prevent leakage. In some embodiments, the thickness of the fins 2521 and the width of the liquid storage groove 2522 are approximately 0.15 mm. The liquid storage groove 2522 can also be used to guide gas, which can lead the gas entering from the air inlet 213 into the liquid storage chamber 211, thereby reducing the negative pressure formed in the liquid storage chamber 211 and making the gas in the liquid storage chamber 211 flow out smoothly.

[0078] In some embodiments, the liquid storage and ventilation structure 252 may further include at least one return air groove 2523; the at least one return air groove 2523 may include at least two return air grooves 2523; the at least two return air grooves 2523 may be correspondingly arranged with the at least two through holes 251, specifically, it may include two return air grooves 2523. The two return air grooves 2523 may be arranged on the plurality of fins 2521 and may be transversely cut across the liquid storage groove 2522 along the direction of the axis of the liquid storage and ventilation structure 252, and extend all the way to the top of the gas-liquid balance element 250, connecting the liquid storage groove 2522 to the liquid storage chamber 211. The width of the return air groove 2523 may be less than or equal to the width of the liquid storage groove 2522, so that the liquid in the liquid storage chamber 211 can flow to each liquid storage groove 2522 through the return air groove 2523. In some embodiments, the width of the return air groove 2523 may be between 0.09 and 0.15.

[0079] In some embodiments, the liquid storage and ventilation structure further includes at least one surface tension isolation groove 2524; the at least one surface tension isolation groove 2524 may be disposed on the plurality of fins 2521 and transversely cuts the liquid storage tank 2522 along a direction parallel to the axis of the liquid storage and ventilation structure 252, which can be used to achieve tension isolation of the liquid in these liquid storage tanks 2522. In some embodiments, the at least one surface tension isolation groove 2524 may include at least two surface tension isolation grooves 2524 corresponding to the at least two through holes 251; specifically, it may include two surface tension isolation grooves 2524, which may be corresponding to the two return air grooves 2523, and are respectively located on two opposite sides of the through hole 251 and at a 180-degree position, both transversely cutting the liquid storage tank 2522 along a direction parallel to the axis of the liquid storage and ventilation structure 252, so as to achieve tension isolation of the liquid in each liquid storage tank 2522.

[0080] In some embodiments, atmospheric pressure return air can enter the liquid storage tanks 2522 of each layer through the surface tension isolation groove 2524 and accumulate towards the return air groove 2523. When a negative pressure is generated in the liquid storage chamber 211, it can only draw in air from the return air groove 2523, while the gas entering through the air inlet 213 can enter each layer of liquid storage tank 2522 through the liquid isolation groove 524 and slowly flow into the liquid storage chamber 211 from the return air groove 2523 until gas-liquid balance is reached. When the gas pressure in the liquid storage chamber 211 is balanced, liquid can also gradually flow downward into the liquid storage tanks 2522 of each layer through the return air groove 2523, thus preventing liquid leakage through the atomizing component 211. In some embodiments, the width of the surface tension isolation groove 2524 is between 1.2 and 1.7 mm.

[0081] In some embodiments, the liquid storage and ventilation structure further includes an air inlet groove 2525, which may be disposed at the lower part of the liquid isolation groove 524 and may be disposed opposite to the return air groove 2523. It may be a wide groove and communicates with the air inlet 213, allowing gas to enter the liquid isolation groove 524.

[0082] In some embodiments, the liquid storage and ventilation structure further includes at least one through groove 2526; the at least one through groove 2526 can be one or more; in some embodiments, the at least one through groove 2526 is correspondingly provided with the return air groove 2523, and there can be two of them, which can be used to connect the through hole 251 and the liquid storage tank 2522; thereby enabling the liquid storage tank 2522 to exchange liquid with the liquid guiding element 260, that is, when the liquid guiding element 260 is insufficient, the liquid stored in the liquid storage tank 2522 can enter the liquid guiding element 260 through the through groove 2526, thereby maintaining a smooth liquid supply and preventing the atomizing core 231 from dry burning. Conversely, when the liquid guiding element 260 is sufficient and the liquid storage tank 2522 is insufficient, the liquid in the liquid guiding element 260 can be returned to the liquid storage tank 2522 by the through groove 2526. In some embodiments, the width of the through groove can be 0.01mm-2mm.

[0083] In some embodiments, the liquid storage and ventilation structure 252 further includes at least one isolation portion 2528; the isolation portion may be disposed between the plurality of fins 2521, and the at least one isolation portion 2528 may also be provided with one or more isolation portions 2528, which can divide the plurality of fins into at least two liquid storage and ventilation units arranged axially. In this embodiment, there may be one isolation portion, which can divide the plurality of fins 2521 into liquid storage and ventilation units at both ends. When the liquid storage tank in the liquid storage and ventilation unit near one end of the liquid storage cavity 211 is full of liquid, it can sequentially enter the next liquid storage and ventilation unit. The isolation portion 2528 may be provided with a cut surface 25281; the cut surface 25281 may be located on one side of the surface tension isolation groove 2524 to facilitate the flow of gas and liquid. In some embodiments, the width of the liquid storage tank 2522 in the liquid storage and ventilation unit near the liquid storage cavity is greater than the width of the liquid storage tank 2522 away from the liquid storage cavity 211, thereby preventing leakage. In some embodiments, the gas-liquid balance element 250 may further include a positioning structure 254; the positioning structure 254 may be a positioning post, which may be disposed at one end of the liquid storage and ventilation structure 252 away from the liquid storage chamber 211, and may be used to position the gas-liquid balance element 250.

[0084] In some embodiments, the at least two liquid guiding elements 260 are correspondingly disposed with at least two through holes 251. The at least two liquid guiding elements 260 may be disposed through the through holes 251 and located at both ends of the atomizing core 231, connecting to the atomizing core 231 for liquid guiding. The liquid guiding element 260 may be a cotton wick; however, it is understood that in other embodiments, the liquid guiding element 260 may not be limited to a cotton wick.

[0085] In some embodiments, the first sealing structure 270 can be a sealing sleeve, which can be fitted onto the gas-liquid balance element 250, and can be provided with clearance holes corresponding to the liquid guiding element 260, the gas return groove 2523, and the gas outlet channel 253. The first sealing structure 270 can be a silicone sleeve or a rubber sleeve.

[0086] In some embodiments, the electrode assembly 290 may include two electrode posts, a positive electrode post and a negative electrode post, which are arranged side by side on the base 221 and located on both sides of the air intake channel 230. One end of the electrode post, which passes through the base 220, can be electrically connected to the heating element 232 of the atomizing assembly 230 by means of a lead wire, and the other end can be electrically connected to a power supply device.

[0087] Figures 15 to 17Some preferred embodiments of the atomizing housing of the present invention are also shown. The atomizing housing of the present invention forms the gas-liquid balance element 250 of the present invention. The atomizing housing may include a body; the atomizing chamber 2527 may be formed inside the body; the body may be cylindrical, and may include at least one through hole 251, a liquid storage and ventilation structure 252, and an airflow channel; the at least one through hole 251 may be arranged longitudinally, and may be used for mounting the liquid guiding element 260. In some embodiments, the at least one through hole 251 may include at least two through holes 251, and the at least two through holes 251 may be arranged on both sides of the airflow channel. It is understood that in some other embodiments, the number of through holes 251 may not be limited to two. The liquid storage and ventilation structure 252 may be arranged around the at least one through hole 251, and its specific structure has been discussed above and will not be repeated here. The airflow channel may be arranged on the body, and may communicate with the atomizing chamber 2527, and may allow the mist in the atomizing chamber 2527 to be output.

[0088] Figures 18 to 19 The third embodiment of the electronic atomizing device of the present invention is shown. This electronic atomizing device can be used in the fields of electronic cigarettes and medical atomization. It has the advantages of smooth liquid medium supply, high safety performance and low leakage.

[0089] The electronic atomizing device may include an atomizer 300 and a power supply device; the power supply device may be electrically connected to the atomizer 300 to supply power to the atomizer 300, thereby facilitating atomization in the atomizer 300.

[0090] like Figure 18 and Figure 19 As shown, in some embodiments, the atomizer 300 may include a liquid storage unit A and an atomizing unit B; the liquid storage unit A and the atomizing unit B are connected in a liquid-conducting connection. The liquid storage unit A is used to store the liquid medium and discharge the mist; the atomizing unit B can be used to heat and atomize the liquid medium.

[0091] like Figures 19 to 20As shown, the liquid storage unit A may include a housing 310; the housing 310 may be fitted around the atomizing unit B, and its inner side may be used to form a liquid storage cavity 311 for containing the liquid medium. Specifically, a space is left between the housing 310 and the upper part of the atomizing unit B, and this space may form the liquid storage cavity 311. The inner side of the housing 310 is also provided with a mist channel 312, which may be arranged along the axial direction of the housing 310 and may be connected to the air guide of the atomizing unit B to output the mist formed by the atomizing unit B. The end of the mist channel 312 away from the atomizing unit B is provided with an air outlet, which may form a mouthpiece for the user to inhale the mist. A sealing element may be provided on the air outlet to seal the air outlet when the atomizer 10 is not in use, to prevent debris from entering the mist channel 12. A gap is provided between the mist channel 312 and the side wall of the outer casing 310 to facilitate liquid flow around the outer periphery of the mist channel 312. The liquid storage chamber 311 may be located around the outer periphery of the mist channel 312.

[0092] In some embodiments, the atomizing unit B may be disposed within the housing 310. It is understood that in other embodiments, the atomizing unit B may also be located outside the housing 310 and at its lower part. The atomizing unit B may include a base 320, an atomizing assembly 330, an atomizing shell 340, and at least one gas-liquid balance element 350. The base 320 is for mounting the atomizing assembly 330, the atomizing shell 340, and the gas-liquid balance element 350, and the housing 310 may be fitted onto the base 320. The atomizing assembly 330 is mounted on the base 320 and housed within the atomizing shell 340, and can be used to heat a liquid medium to form a mist that can be inhaled by a user. The atomizing shell 340 is disposed on the base 320, one end of which can be inserted into the base 320 and detachably connected to the base 320, and can be used to cooperate with the base 320 to mount the atomizing assembly 330. The at least one gas-liquid balance element 350 may include two gas-liquid balance elements. These two gas-liquid balance elements may be located on the first and second sides of the atomizing assembly 330, respectively, and are mounted in the base 320 and pass through the atomizing housing 340, extending towards the outer shell 310. They may be disposed at the lower part of the liquid storage chamber 311, communicating with the liquid storage chamber 311, and can be used to adjust the gas-liquid balance within the liquid storage chamber 311. In some embodiments, the first and second sides of the atomizing assembly 330 are two opposite sides of the atomizing assembly 330.

[0093] In some embodiments, the atomizing unit B may further include a first sealing structure 370, a second sealing structure 380, and an electrode assembly 390. The first sealing structure 370 may be disposed between the atomizing housing 340 and the liquid storage chamber 311, and can be used to seal the gap formed between the housing 310 and the atomizing unit B to prevent leakage. The second sealing structure 380 may be sleeved on the base 320, and can seal the housing 310 to the base 320. The electrode assembly 390 may extend from the base 320 and be electrically connected to the atomizing assembly 330.

[0094] For example Figure 20 and Figure 21 As shown, the base 320 may include a base body 321 and two mounting seats 324 spaced apart on the base body 321. The shape and size of the base body 321 are adapted to the shape and size of the opening end of the housing 310, and it can be used to seal the opening of the housing 310. The two mounting seats 324 are separately arranged and can be used to support the atomizing assembly 330 and to mount the gas-liquid balance element 350.

[0095] At least one air inlet 3211 may be provided on the base 320; the at least one air inlet 3211 may include two air inlets 3211; the two air inlets 3211 may be located at the bottom of the base 321 and respectively on both sides of the central axis of the base 321. An air intake channel 323 may also be provided on the base 320; the air intake channel 323 is located at the bottom of the base 321 and between the two air inlets 3211, and is axially arranged to communicate with the atomizing component 330, so as to allow gas to enter the atomizing component 330. The two air inlets 3211 may be located on opposite sides of the air intake channel 323, thereby preventing the gas-liquid balance element 350 from communicating with the air intake channel 323, and thus preventing the negative pressure generated in the mist channel during mist extraction from causing liquid medium leakage. Of course, it is understood that in some other embodiments, when there is only one air inlet 3211, it may be located on one side of the air intake channel 323. A mesh 3231 can be installed on the air intake channel 323; the mesh 3231 can be integrally formed with the base 320. Since the mesh aperture is small, the liquid medium can form a liquid film in each mesh hole, thereby preventing the liquid medium from leaking out.

[0096] Each mounting base 324 may include a boss 3241 and a mounting hole 3242 provided on the boss 3241. The boss 3241 can cooperate with the boss 3241 of another mounting base 324 to support the atomizing assembly 330, and the gap between the two bosses 3241 can form an atomizing chamber communicating with the air intake channel 323. The mounting hole 3242 is correspondingly provided with the air inlet 3211 and communicates with the air intake channel 323. The mounting hole 3242 is provided in the axial direction, and it allows the gas-liquid balance element 350 to be inserted and installed in the base 320. The outer peripheral sidewall of the boss 3241 extends toward the liquid storage chamber 311, and a buckle 243 can be provided on the sidewall opposite to the atomizing chamber 23 to cooperate with the outer atomizing housing 340 for installation.

[0097] In some embodiments, the atomizing component 330 can rest on the protrusions 3241 of the two mounting bases 324, and can abut against the protrusions 3241 respectively. The atomizing component 330 includes a porous ceramic substrate and a heating element; the porous ceramic substrate can be disposed opposite to the base 320, and can be used to absorb liquid. The heating element can be disposed on the porous ceramic substrate, and can be used to heat the liquid medium in the pores to form a mist. For example... Figures 19 to 21 As shown, in some embodiments, an elastic element 333 is also fitted onto the porous ceramic substrate; one end of the elastic element 333 abuts against the top wall of the cover 342 of the atomizing housing 340, and the other end abuts against the porous ceramic substrate. It can be used to prevent the porous ceramic substrate from being crushed, and also serves as a cushioning effect. The elastic element 333 can be a silicone sleeve or a rubber sleeve; it is understood that in some other embodiments, the elastic element 333 is not limited to a silicone sleeve or a rubber sleeve, and in some other embodiments, it can be omitted.

[0098] In some embodiments, the atomizing housing 340 may include a sleeve 341, a cover 342, a positioning part 343, and a buckle 344. The sleeve 341 may be fitted around the gas-liquid balance element 350, and has an air outlet 3411 thereon, which communicates with the atomizing chamber 23 and the mist channel 312 for mist output. The atomizing housing 340 may have at least two liquid outlets 3412; the at least two liquid outlets 3412 may be formed on the sleeve 341 and located on both sides of the air outlet 3411, specifically, they are located on the first side and the second side of the atomizing assembly 330, and are connected to the liquid guide of the atomizing assembly 330 to supply liquid medium to the atomizing assembly 330. The sleeve 341 is also provided with through holes 3413, the number and position of which correspond to the gas-liquid balance element 350. These through holes are located on the first and second sides of the atomizing assembly 330, allowing the gas-liquid balance element 350 to pass through. The cover 342 is disposed inside the sleeve 341, below the air outlet 3411, and is spaced from the air outlet 3411 to form a through groove penetrating both opposite sides of the sleeve 341. This through groove communicates with the air outlet 3411 to facilitate gas output. The inner side of the cover 342 can form a receiving space to accommodate the atomizing assembly 330. The positioning part 343 is disposed on the sleeve 341, and there can be two sets of positioning parts. The two sets of positioning parts can be located on two opposite sides in the long axis direction of the sleeve 341. Each set of positioning parts can include two positioning parts 343, which are spaced apart and located on both sides of the cover 342, extending toward the base 320 to connect with the boss 3241. The buckle 344 can be disposed on two opposite sides in the short axis direction of the sleeve 341, extending toward the base 320 to fasten in the buckle hole 223 of the base 320.

[0099] like Figures 20 to 23 As shown, in some embodiments, the overall height of each gas-liquid balance element 350 can be adapted to the overall height of the atomizing unit B. The two gas-liquid balance elements 350 can be located on the side opposite to the air outlet 3411 of the two liquid outlets 3412, respectively. They are used to balance the gas and liquid in the liquid storage chamber 311, thereby reducing the negative pressure in the liquid storage chamber 311, allowing gas to flow smoothly from the liquid outlets 3412 to the atomizing assembly 330. This prevents the atomizing assembly 330 from being damaged by overheating due to dry burning and avoids the generation of burnt smells and harmful substances; additionally, it can store liquid to prevent leakage. In some embodiments, each gas-liquid balance element 350 may include a column 351 and a liquid storage and ventilation structure 352 disposed around the column. The column 351 may be longitudinally elongated, allowing the liquid storage and ventilation structure 352 to be installed. The liquid storage and ventilation structure 352 can be connected to the liquid storage chamber 311, and can be used to adjust the gas-liquid balance in the liquid storage chamber 311.

[0100] In some embodiments, the liquid storage and ventilation structure 352 may include a plurality of fins 3521; the plurality of fins 3521 may be arranged parallel to each other along the axial direction. A liquid storage groove 3522 penetrating the outer peripheral surface of the liquid storage and ventilation structure 352 may be formed between each pair of adjacent fins 3521; the width of the liquid storage groove 3522 is small enough to generate capillary force on the liquid medium, so that when the liquid flows into the liquid storage groove 3522, a liquid film can be formed in the liquid storage groove 3522, and thus it can be stored in the liquid storage groove 3522 to prevent leakage. In some embodiments, the thickness of the fins 3521 and the width of the liquid storage groove 3522 are approximately 0.15 mm. The liquid storage groove 3522 can also be used to guide gas, which can lead the gas entering from the air inlet 3211 into the liquid storage chamber 311, thereby reducing the negative pressure formed in the liquid storage chamber 311 and making the gas in the liquid storage chamber 311 flow out smoothly.

[0101] In some embodiments, the liquid storage and ventilation structure may further include a return air groove 3523. The return air groove 3523 may be disposed on the plurality of fins 3521 and may transversely cut through the liquid storage groove 3522 along the axis of the liquid storage and ventilation structure 352, extending to the top of the gas-liquid balance element 350, connecting the liquid storage groove 3522 to the liquid storage chamber 311. The width of the return air groove 3523 may be less than or equal to the width of the liquid storage groove 3522, thereby allowing the liquid in the liquid storage chamber 311 to flow through the return air groove 3523 to each liquid storage groove 3522. In some embodiments, the width of the return air groove 3523 may be between 0.09 and 0.15 mm.

[0102] In some embodiments, the liquid storage and ventilation structure further includes a surface tension isolation groove 3524. The surface tension isolation groove 3524 can be disposed on the plurality of fins 3521 and transversely cuts the liquid storage tank 3522 along a direction parallel to the axis of the liquid storage and ventilation structure 352, thereby achieving tension isolation of the liquid in these liquid storage tanks 3522. In some embodiments, the surface tension isolation groove 3524 and the return air groove 3523 are respectively located on two opposite sides of the column 351 at a 180-degree angle, and both transversely cut the liquid storage tank 3522 along a direction parallel to the axis of the liquid storage and ventilation structure 352, so as to achieve tension isolation of the liquid in each liquid storage tank 3522.

[0103] In some embodiments, atmospheric pressure return air can enter the liquid storage tanks 3522 of each layer through the surface tension isolation groove 3524 and accumulate towards the return air groove 3523. When a negative pressure is generated in the liquid storage chamber 311, it can only draw in air from the return air groove 3523, while the gas entering through the air inlet 3211 can enter each layer of liquid storage tank 3522 through the surface tension isolation groove 3524 and slowly flow into the liquid storage chamber 311 from the return air groove 3523 until gas-liquid balance is reached. When the gas pressure in the liquid storage chamber 311 is balanced, the liquid can also gradually flow downward into the liquid storage tanks 3522 of each layer through the return air groove 3523, thus preventing liquid leakage through the atomizing component 11. In some embodiments, the width of the surface tension isolation groove 3524 is between 1.2 and 1.7 mm.

[0104] In some embodiments, the liquid storage and ventilation structure further includes an air inlet groove 3525, which may be disposed at the lower part of the surface tension isolation groove 3524 and may be disposed offset from the return air groove 3523. It may be a wide groove and communicates with the air inlet 3211, allowing gas to enter the surface tension isolation groove 3524.

[0105] In some embodiments, the liquid storage and ventilation structure further includes at least one isolation section 3528; the isolation section may be disposed between the plurality of fins 3521, and the at least one isolation section 3528 may also be provided with one or more isolation sections 3528, which can divide the plurality of fins into at least two liquid storage and ventilation units arranged axially. In this embodiment, there may be one isolation section, which can divide the plurality of fins 3521 into liquid storage and ventilation units at both ends. When the liquid storage tank in the liquid storage and ventilation unit near one end of the liquid storage cavity 311 is full of liquid, it can sequentially enter the next liquid storage and ventilation unit. The isolation section 3528 may be provided with a cross-section 5281; the cross-section 5281 may be located on one side of the surface tension isolation groove 3524 to facilitate the flow of gas and liquid. In some embodiments, the width of the liquid storage tank 3522 in the liquid storage and ventilation unit near the liquid storage cavity is greater than the width of the liquid storage tank 3522 away from the liquid storage cavity 311, thereby preventing leakage.
