Description
Electronic atomizing devices and atomizers Technical Field
[0001] This invention relates to the field of atomization technology, and more specifically, to an electronic atomization device and atomizer. Background Technology
[0002] Most large-capacity disposable electronic atomizing devices on the market currently employ a technical solution that simply increases the capacity of a small-capacity (e.g., 0.5 ml or 1 ml) reservoir without fully considering the secondary problems and technical incompatibilities that arise from this increased capacity. Leakage occurs when the aerosol-generating matrix in the reservoir is reduced to half its original capacity, and continued use will lead to severe leakage or blockage. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide an improved electronic atomizing device and atomizer, which addresses the above-mentioned deficiencies of the prior art.
[0004] The technical solution adopted by the present invention to solve its technical problem is: to construct an electronic atomizing device, including a first liquid storage chamber and a second liquid storage chamber arranged side by side, a connecting channel connecting the bottom of the first liquid storage chamber and the bottom of the second liquid storage chamber, an atomizing core that is fluidly connected to both the first liquid storage chamber and the second liquid storage chamber, and an air exchange channel connected to the first liquid storage chamber.
[0005] In some embodiments, the first liquid storage tank, the connecting channel, and the second liquid storage tank are sequentially connected to form a U-shaped tube connecting structure.
[0006] In some embodiments, the electronic atomizing device includes: a cylindrical liquid storage section; and a partition wall disposed within the liquid storage section to divide the space within the liquid storage section into a first liquid storage chamber and a second liquid storage chamber.
[0007] In some embodiments, the electronic atomizing device includes an atomizing base, which is at least partially embedded in the lower opening of the liquid storage section and covers the lower openings of the first and second liquid storage chambers.
[0008] In some embodiments, the ventilation channel is formed by a recess in the outer surface of the atomizing seat.
[0009] In some embodiments, the ventilation trough includes at least one ventilation inlet communicating with the outside atmosphere, at least one ventilation outlet communicating with the first liquid storage tank, and a main channel connecting the at least one ventilation inlet and the at least one ventilation outlet.
[0010] In some embodiments, a plurality of baffles are provided at intervals along the extension direction of the main channel.
[0011] The main channel has an upper side and a lower side that are arranged opposite to each other. One of the two adjacent baffles extends downward from the upper side and is spaced apart from the lower side, while the other extends upward from the lower side and is spaced apart from the upper side.
[0012] In some embodiments, there are at least two ventilation outlets.
[0013] In some embodiments, the communication channel is formed by a recess in the top surface of the atomizing seat.
[0014] In some embodiments, the atomizing seat has a first guide slope and a second guide slope.
[0015] The first flow-guiding slope defines at least a portion of the bottom wall surface of the first liquid storage tank, and the first flow-guiding slope has an inclination toward the communicating channel.
[0016] The second flow guide slope defines at least a portion of the bottom wall surface of the second liquid storage tank, and the second flow guide slope has an inclination toward the communicating channel.
[0017] The present invention also provides an atomizer, including a first liquid storage chamber and a second liquid storage chamber arranged side by side, a connecting channel connecting the bottom of the first liquid storage chamber and the bottom of the second liquid storage chamber, an atomizing core in fluid communication with both the first liquid storage chamber and the second liquid storage chamber, and an air exchange channel communicating with the first liquid storage chamber.
[0018] In some embodiments, the atomizer includes: a liquid storage shell having a first liquid storage compartment and a second liquid storage compartment internally separated; and an atomizing seat at least partially disposed in the liquid storage shell and defining at least a portion of the bottom wall surface of the first liquid storage compartment and at least a portion of the bottom wall surface of the second liquid storage compartment.
[0019] In some embodiments, the connecting channel and the ventilation channel are at least partially formed in the atomizing seat.
[0020] Implementing this invention has at least the following beneficial effects: the first liquid storage tank is directly connected to the ventilation channel, while the second liquid storage tank is indirectly connected to the first liquid storage tank and the ventilation channel in sequence through a connecting channel. When the negative pressure in the liquid storage tank increases due to the consumption of the aerosol generating matrix, outside air will directly enter the first liquid storage tank through the ventilation channel, and the aerosol generating matrix in the first liquid storage tank will flow to the second liquid storage tank through the connecting channel, thereby balancing the pressure change in the second liquid storage tank caused by the consumption of the aerosol generating matrix. This cycle continues until the aerosol generating matrix in the first liquid storage tank is completely consumed. After the aerosol generating matrix in the first liquid storage tank is completely consumed, the first liquid storage tank can serve as a pressure relief storage space for the second liquid storage tank, thereby reducing the risk of leakage.

[0038] Figure 1 shows a schematic diagram of the principle of an electronic atomizing device 1 in some embodiments of the present invention. The electronic atomizing device 1 includes a first liquid storage chamber 121, a second liquid storage chamber 122, a connecting channel 141 connecting the first liquid storage chamber 121 and the second liquid storage chamber 122, an atomizing core 20 in fluid communication with both the first liquid storage chamber 121 and the second liquid storage chamber 122, and a ventilation channel 142 connected to the first liquid storage chamber 121. The first liquid storage chamber 121 is directly connected to the ventilation channel 142, and the second liquid storage chamber 122 is indirectly connected to the first liquid storage chamber 121 and the ventilation channel 142 in sequence.
[0039] The first liquid storage chamber 121 and the second liquid storage chamber 122 are used to contain the aerosol generation matrix. The liquid storage spaces of the first liquid storage chamber 121 and the second liquid storage chamber 122 may be the same or different. The aerosol generation matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.
[0040] As shown by the arrows in Figure 1, the first liquid storage chamber 121 and the second liquid storage chamber 122 can supply liquid to the atomizing core 20 from both sides, respectively. After being energized, the atomizing core 20 heats and atomizes the aerosol to generate a matrix. The heating method of the atomizing core 20 is not limited; for example, it can use one or more of the following heating methods: resistance heating, electromagnetic heating, infrared heating, and chemical heating.
[0041] The first liquid storage tank 121 and the second liquid storage tank 122 can be arranged side by side and can have the same height. Of course, in other embodiments, the first liquid storage tank 121 and the second liquid storage tank 122 can also have different heights.
[0042] The bottom of the first liquid storage chamber 121 is connected to the bottom of the second liquid storage chamber 122 through a connecting channel 141, so that the first liquid storage chamber 121 and the second liquid storage chamber 122 can still be fluidly connected at the end of the aerosol generation matrix consumption.
[0043] The shape and structure of the connecting channel 141 are not limited. For example, as shown in Figure 1, a connecting port or connecting groove can be simply provided at the bottom junction of the first liquid storage tank 121 and the second liquid storage tank 122 to form the connecting channel 141. Alternatively, as shown in Figure 2, a curved connecting channel 141 can be provided below the first liquid storage tank 121 and the second liquid storage tank 122, so that the first liquid storage tank 121, the second liquid storage tank 122, and the connecting channel 141 together form a U-shaped tube connecting structure.
[0044] It should be noted that the U-shaped tube connection structure formed by the first liquid storage tank 121, the connecting channel 141, and the second liquid storage tank 122 does not necessarily have to be strictly "U". The core function of the U-shaped tube connection structure is to maintain liquid connectivity between the first liquid storage tank 121 and the second liquid storage tank 122 at the bottom. This connectivity allows the liquid to flow freely between the first liquid storage tank 121 and the second liquid storage tank 122, thereby achieving functions such as pressure balance. Therefore, the design of the U-shaped tube connection structure can be adjusted according to actual needs. For example, the first liquid storage tank 121 and the second liquid storage tank 122 can be connected at the bottom through a connecting channel 141 of a straight, V-shaped, S-shaped, or spiral shape.
[0045] The working principle of the electronic atomizing device 1 is as follows: During the atomization process, the consumption of the aerosol generating matrix increases the negative pressure in the storage chamber. When the internal and external pressures are unbalanced, outside air enters the first storage chamber 121 directly through the ventilation channel 142. The aerosol generating matrix in the first storage chamber 121 flows to the second storage chamber 122 through the connecting channel 141, thus balancing the pressure change in the second storage chamber 122 caused by the consumption of the aerosol generating matrix. This cycle continues until the aerosol generating matrix in the first storage chamber 121 is completely consumed. After the aerosol generating matrix in the first storage chamber 121 is consumed, the first storage chamber 121 can serve as a pressure relief storage space for the second storage chamber 122, thereby reducing the risk of leakage. When the aerosol generating matrix in the first storage chamber 121 is consumed, because the air capacity of the first storage chamber 121 is limited, the increase in air pressure can be resolved by a small amount of liquid overflowing into the ventilation channel 142.
[0046] Figures 3 to 9 illustrate an electronic atomizing device 1 in some embodiments of the present invention. The shape of the electronic atomizing device 1 is not limited; for example, it can be various shapes such as square columnar, elliptical columnar, racetrack-shaped columnar, or cylindrical.
[0047] The electronic atomizing device 1 includes a housing 10 and an atomizing core 20, a battery 30, and a control circuit disposed within the housing 10. The control circuit is electrically connected to the atomizing core 20 and the battery 30, respectively, and is used to control the power supply and disconnection of the battery 30 to the atomizing core 20.
[0048] The housing 10 has a first liquid storage chamber 121 and a second liquid storage chamber 122 separated within it. The bottom of the first liquid storage chamber 121 and the bottom of the second liquid storage chamber 122 are connected by a connecting channel 141. The atomizing core 20 is in fluid communication with the first liquid storage chamber 121 and the second liquid storage chamber 122 respectively.
[0049] An air intake 103 is formed at one end of the housing 10 (shown as the upper end in the diagram), and an air inlet 101 is formed on the bottom wall of the housing 10. An airflow channel 102 is formed inside the housing 10, communicating with both the air intake 103 and the air inlet 101. The atomizing core 20 is in fluid communication with the airflow channel 102. When the user inhales through the air intake 103, the airflow enters through the air inlet 101, flows through the atomizing core 20, carries away the aerosol generated after atomization by the atomizing core 20, and further flows towards the air intake 103.
[0050] Of course, it is understood that the air inlet 101 is not limited to being located on the bottom wall of the housing 10, but can be located at any position on the housing 10, such as on the side wall or top wall of the housing 10.
[0051] In some embodiments, the electronic atomizing device 1 may further include an airflow sensor 40 disposed in the housing 10 and in fluid communication with the airflow channel 102. The airflow sensor 40 is electrically connected to the control circuit and is capable of detecting changes in the suction airflow within the airflow channel 102. The control circuit can control whether to activate the electronic atomizing device 1 based on the signal emitted by the airflow sensor 40.
[0052] The housing 10 may include an outer shell 11, a support 12 disposed within the outer shell 11, and a suction nozzle 13 disposed at the upper end of the outer shell 11. A first liquid storage chamber 121 and a second liquid storage chamber 122 are formed side by side within the support 12. The outer shell 11 is cylindrical and has an opening at the upper end to facilitate the insertion of components such as the support 12. The suction nozzle 13 covers the upper opening of the outer shell 11 and forms an air intake 103 thereon.
[0053] Of course, in other embodiments, the structure of the housing 10 can be arbitrarily modified. For example, an opening can be made at the bottom or side of the housing 11, so that the suction nozzle 13 can also be integrally formed with the housing 11. Alternatively, the bracket 12 can also be integrally formed with the housing 11 and / or the suction nozzle 13.
[0054] The support 12 includes a liquid storage section 123 and a partition wall 124 disposed within the liquid storage section 123. The liquid storage section 123 is cylindrical, and the partition wall 124 divides the space within the liquid storage section 123 to form a first liquid storage chamber 121 and a second liquid storage chamber 122. A longitudinally extending air outlet pipe 1240 may also be formed on the partition wall 124, with both ends of the air outlet pipe 1240 connected to an air intake port 103 and an air inlet port 101, respectively. The inner wall surface of the air outlet pipe 1240 defines a portion of the airflow channel 102.
[0055] In some embodiments, the electronic atomizing device 1 further includes a sealing cap 16 disposed in the housing 11. The sealing cap 16 may be made of an elastic sealing material such as silicone. The sealing cap 16 covers at least the liquid storage section 123 and seals the upper openings of the first liquid storage chamber 121 and the second liquid storage chamber 122, so that the first liquid storage chamber 121 and the second liquid storage chamber 122 are not connected at the upper end.
[0056] In some embodiments, the bracket 12 may further include a mounting portion 125, on which a mounting space 1250 for mounting the battery 30 is formed. At least one side of the mounting space 1250 is open to facilitate the insertion of the battery 30.
[0057] The support 12 may have a length direction and a width direction. The mounting part 125 and the liquid storage part 123 may be arranged side by side in the length direction of the support 12. The first liquid storage chamber 121 and the second liquid storage chamber 122 may be arranged side by side in the width direction of the support 12.
[0058] In this embodiment, the support 12 is a one-piece molded structure. It can be understood that in other embodiments, the support 12 may also be a split structure. For example, the liquid storage part 123 and the partition wall 124 may be molded separately and then assembled together, or the liquid storage part 123 and the mounting part 125 may be molded separately and then assembled together.
[0059] The atomizing core 20 may include a liquid-absorbing element 21 and a heating element 22 in contact with the liquid-absorbing element 21. The liquid-absorbing element 21 is in fluid communication with the first liquid storage chamber 121 and the second liquid storage chamber 122, respectively, and can draw aerosol from the first liquid storage chamber 121 and the second liquid storage chamber 122 to generate a matrix and transfer it to the heating element 22.
[0060] The liquid absorption element 21 can adopt any structure that can transfer or deliver the aerosol generation matrix to the heating element 22. Typically, the liquid absorption element 21 can conduct liquid through capillary force.
[0061] In some embodiments, the liquid-absorbing element 21 may be made of a porous material with capillary force, including but not limited to cotton-like materials (including natural cotton and / or synthetic cotton) or inorganic porous materials (e.g., ceramics, glass fibers, etc.). Of course, in other embodiments, micropores or microgrooves with capillary force can also be formed on the liquid-absorbing element 21 through microfabrication processes. In this way, the liquid-absorbing element 21 is not limited to porous materials, and it can also be made of non-porous materials such as glass and metal.
[0062] The heating element 22 can be a resistance heating element, which can convert electrical energy into heat energy by utilizing the resistance heating effect generated when current passes through a conductive material. The specific structure of the resistance heating element is not limited. For example, it can be a mesh, array or fabric formed by metal conductive wires or conductive sheets, or it can be a resistance heating film formed on the liquid-absorbing element 21 by screen printing or other methods.
[0063] In some embodiments, the liquid-absorbing element 21 may be generally cylindrical (e.g., cylindrical), and an air passage 210 may be formed axially through its interior. The two ends of the air passage 210 are respectively connected to the air inlet 101 and the air outlet 1240. The heating element 22 may be disposed on the inner wall surface of the liquid-absorbing element 21.
[0064] In some embodiments, the atomizing core 20 may further include a support tube 24, which is sleeved on the liquid-absorbing element 21 to support and fix the liquid-absorbing element 21. Two liquid inlet holes 240 are provided on the side wall of the support tube 24 to allow the liquid-absorbing element 21 to be in fluid communication with the first liquid storage chamber 121 and the second liquid storage chamber 122, respectively.
[0065] The support tube 24 can be disposed at the lower end of the air outlet pipe 1240 and can be coaxially disposed with the air outlet pipe 1240. In some embodiments, the upper end of the support tube 24 and the lower end of the air outlet pipe 1240 can be tightly sleeved together, for example, the upper end of the support tube 24 can be tightly embedded in the lower end of the air outlet pipe 1240, which is beneficial to improving the airtightness of the joint between the two.
[0066] In some embodiments, the atomizing core 20 may further include a liquid guide 23 surrounding the liquid absorption element 21. The aerosol generating matrix flowing in through the two liquid inlets 240 is delivered to the liquid absorption element 21 via the liquid guide 23.
[0067] The liquid guide 23 has a stronger liquid absorption capacity than the liquid absorption element 21, enabling it to absorb liquid from the first liquid storage chamber 121 and the second liquid storage chamber 122 more quickly and guide it to the liquid absorption element 21. Preferably, the liquid guide 23 is made of a porous material such as cotton (including natural cotton and / or synthetic cotton). Of course, in other embodiments, the liquid guide 23 may also be made of other porous materials (e.g., ceramics, glass fibers, etc.).
[0068] The housing 10 may further include an atomizing seat 14, which is disposed at the lower end of the bracket 12 and covers the lower openings of the first liquid storage chamber 121 and the second liquid storage chamber 122. The atomizing seat 14 may be made of an elastic sealing material such as silicone to improve its sealing performance. Of course, in other embodiments, the atomizing seat 14 may also be made of other materials such as plastic.
[0069] In some embodiments, the atomizing seat 14 may be at least partially embedded in the lower opening of the liquid storage section 123, and at least a portion of the outer wall surface of the atomizing seat 14 may be sealed to the lower inner wall surface of the liquid storage section 123, which is beneficial to improving the sealing effect.
[0070] The top surface of the atomizing seat 14 defines at least a portion of the bottom wall surface of the first liquid storage chamber 121 and at least a portion of the bottom wall surface of the second liquid storage chamber 122. In some embodiments, the top of the atomizing seat 14 has a first guide slope 1411 and a second guide slope 1412, which define at least a portion of the bottom wall surface of the first liquid storage chamber 121 and at least a portion of the bottom wall surface of the second liquid storage chamber 122, respectively. The first guide slope 1411 and the second guide slope 1412 can both be planes, curved surfaces, or a combination of planes and curved surfaces. The first guide slope 1411 and the second guide slope 1412 each have a slope inclined towards the corresponding liquid inlet 240, which facilitates the flow of the aerosol generating matrix on the first guide slope 1411 and the second guide slope 1412 away from the liquid inlet 240 towards the liquid inlet 240 under the action of gravity, thereby improving the utilization rate of the aerosol generating matrix. Of course, in other embodiments, the top of the atomizing seat 14 may not have a flow guide slope.
[0071] The top surface of the atomizer base 14 can be recessed to form a receiving cavity 143, and the lower part of the atomizer core 20 can be inserted into the receiving cavity 143. In some embodiments, the receiving cavity 143 can extend downward from the top surface of the atomizer base 14 but does not penetrate through the atomizer base 14, that is, the bottom of the receiving cavity 143 has a bottom wall 144, and an air inlet 1440 for connecting the air inlet 101 and the airflow hole 210 is formed on the bottom wall 144.
[0072] The bottom wall 144 serves two purposes: firstly, it supports and cushions the atomizing core 20; secondly, it prevents condensate from falling directly into the airflow hole 210 and the air outlet pipe 1240, thus preventing leakage. Furthermore, the cross-sectional area of the air inlet 1440 is smaller than that of the receiving cavity 143, which also helps reduce leakage.
[0073] In some embodiments, the upper surface of the air inlet 1440 may be higher than the bottom wall 144, thereby further reducing leakage. In addition, the space formed between the bottom wall 144 and the bottom surface of the liquid-absorbing element 21 can also store a certain amount of leakage. When the electronic atomizing device 1 is inverted or tilted, the leakage in this space can flow back to the liquid-absorbing element 21 for reuse.
[0074] The lower end of the partition wall 124 can abut against the atomizing base 14 and be sealed with the atomizing base 14. In some embodiments, the top surface of the atomizing base 14 may also be recessed to form a slot 145, and the lower end of the partition wall 124 is formed with a flange 1241, which is sealed and inserted into the slot 145. Of course, in other embodiments, the top surface of the atomizing base 14 may not be recessed to form a slot 145, and the lower end of the partition wall 124 may directly abut against the top surface of the atomizing base 14.
[0075] The connecting channel 141 can be formed on the atomizing seat 14, or on the partition wall 124, or it can be partially formed on the atomizing seat 14 and partially formed on the partition wall 124. Specifically, in this embodiment, a connecting groove 1410 is formed in the recessed top surface of the atomizing seat 14, and the connecting groove 1410 forms the connecting channel 141.
[0076] The connecting groove 1410 can extend approximately along the width direction of the atomizing seat 14, that is, the extension direction of the connecting groove 1410 is approximately consistent with the parallel direction of the first liquid storage chamber 121 and the second liquid storage chamber 122. The first guide slope 1411 and the second guide slope 1412 also have slopes facing the connecting groove 1410, so that the first liquid storage chamber 121, the connecting channel 141, and the second liquid storage chamber 122 are connected to form a U-shaped tube connecting structure. In this way, when the pressure in the liquid storage chamber increases, the aerosol generating matrix in the second liquid storage chamber 122 can flow smoothly to the first liquid storage chamber 121, and when the pressure in the liquid storage chamber recovers, the aerosol generating matrix in the first liquid storage chamber 121 can also be smoothly pushed back to the second liquid storage chamber 122.
[0077] In some embodiments, the communication channel 141 may be disposed on one side of the receiving cavity 143 and communicate with the receiving cavity 143. Of course, in other embodiments, the communication groove 1410 may also be disposed at other positions of the atomizing seat 14 and not communicate with the receiving cavity 143.
[0078] The slot 145 can extend generally along the length of the atomizing base 14, and can extend inward from one side of the atomizing base 14 to connect with the communication channel 141. The bottom wall surfaces of the slot 145 and the communication channel 141 can be generally located on the same horizontal plane, which facilitates manufacturing and assembly. Of course, in other embodiments, the bottom wall surface of the slot 145 can also be higher or lower than the bottom wall surface of the communication channel 141.
[0079] The lower end of the partition wall 124 does not have a flange 1241 at the position corresponding to the connecting groove 1410, so that the lower end of the partition wall 124 forms a notch 1242 at that position. The notch 1242 and the connecting groove 1410 cooperate to define the connecting channel 141.
[0080] The electronic atomizing device 1 also includes a ventilation channel 142 that connects the first liquid storage chamber 121 to the outside atmosphere. In this embodiment, the ventilation channel 142 is formed between the outer wall surface of the atomizing seat 14 and the inner wall surface of the liquid storage section 123.
[0081] Specifically, the outer wall surface of the atomizing seat 14 is recessed to form a ventilation groove 1420. After the atomizing seat 14 is embedded in the liquid storage part 123, the ventilation groove 1420 is covered by the liquid storage part 123 to form a ventilation channel 142. Of course, in other embodiments, the ventilation channel 142 may also be formed by the recess of the inner wall surface of the liquid storage part 123, or by the joint recess of the inner wall surface of the liquid storage part 123 and the outer wall surface of the atomizing seat 14.
[0082] The ventilation trough 1420 (or ventilation channel 142) has at least one ventilation inlet 1421 that communicates with the outside atmosphere, at least one ventilation outlet 1422 that communicates with the first liquid storage tank 121, and a main channel 1423 that connects the at least one ventilation inlet 1421 and the at least one ventilation outlet 1422.
[0083] The main channel 1423 is generally S-shaped. The S-shaped design can utilize the outer space of the atomizing seat 14, which is beneficial for fully accommodating the aerosol generation matrix that leaks into the main channel 1423. In addition, the ventilation inlet 1421 and the ventilation outlet 1422 can be located on different sides of the atomizing seat 14 (e.g., two opposite sides), and the main channel 1423 is arranged around the outer periphery of the atomizing seat 14 in a generally U-shaped or C-shaped manner, which is also beneficial for increasing the length of the main channel 1423 extending between the ventilation inlet 1421 and the ventilation outlet 1422.
[0084] Specifically, the air outlet 1422 may be located on one side of the atomizing seat 14 along the width direction and penetrate through the top surface of the atomizing seat 14, thereby communicating with the first liquid storage chamber 121. The air inlet 1421 may be located on the other side of the atomizing seat 14 along the width direction and penetrate through the bottom surface of the atomizing seat 14.
[0085] The number of ventilation outlets 1422 can be one or more. Preferably, there are at least two ventilation outlets 1422. By increasing the number of ventilation outlets 1422 and reducing the size of a single ventilation outlet 1422, it is beneficial to ensure that the ventilation outlet 1422 is always in a relatively liquid-sealed state, thus preventing the device from being connected to the atmosphere when placed on its side.
[0086] In some embodiments, a plurality of baffles 1424 may be spaced apart within the main channel 1423, and these baffles 1424 may be evenly spaced along the extension direction of the main channel 1423. The vertical orientations of adjacent baffles 1424 are opposite, causing the fluid (air or aerosol generating matrix) to exhibit an S-shaped flow trajectory within the main channel 1423. Specifically, the main channel 1423 has an upper side 1425 and a lower side 1426 disposed opposite to each other. One of the two adjacent baffles 1424 extends downward from the upper side 1425 of the main channel 1423 and is spaced apart from the lower side 1426, while the other extends upward from the lower side 1426 of the main channel 1423 and is spaced apart from the upper side 1425. This design allows the main channel 1423 to have a larger height h (i.e., the distance between the upper side 1425 and the lower side 1426) in the part without the baffle 1424, which helps to increase the liquid storage space of the main channel 1423, while the baffle 1424 can prevent leakage.
[0087] In this embodiment, the upper side 1425 and the lower side 1426 are parallel to each other, and the baffle 1424 is perpendicular to the upper side 1425 and the lower side 1426. Of course, in other embodiments, the structure of the main channel 1423 can be arbitrarily changed as needed. For example, the upper side 1425 and the lower side 1426 may not be parallel, and / or the baffle 1424 may not be perpendicular to the upper side 1425 and the lower side 1426.
[0088] This invention designs two parallel large-capacity storage chambers. When the first storage chamber 121 contains a large amount of aerosol generating matrix, if the pressure inside the storage chamber increases due to a rise in temperature, the aerosol generating matrix can flow smoothly through the ventilation channel 142, quickly balancing the pressure inside the storage chamber and preventing leakage of the aerosol generating matrix from the atomizing core 20. The S-shaped design of the ventilation channel 142 ensures that any leaked aerosol generating matrix can be fully contained, and when the pressure in the storage chamber drops, the aerosol generating matrix can be smoothly pushed back into the storage chamber.
[0089] When the aerosol-generating matrix in the first storage chamber 121 is low or depleted, the space in the first storage chamber 121 where the aerosol-generating matrix has been consumed can be used as the pressure relief storage space for the second storage chamber 122. At this time, the pressure change caused by the temperature rise in the storage chamber is balanced by the first storage chamber 121 and the ventilation channel 142, thereby increasing the pressure relief storage space during large-capacity pressure relief and preventing the aerosol-generating matrix from leaking out of the storage chamber. When the temperature in the storage chamber rises, causing an increase in pressure, the aerosol-generating matrix in the second storage chamber 122 can enter the first storage chamber 121 through the connecting channel 141, and when the temperature drops, it can be effectively pushed back into the second storage chamber 122.
[0090] During the suction process, as the aerosol-generating matrix is consumed, the negative pressure inside the storage chamber increases. When the internal and external pressures are unbalanced, outside air enters the first storage chamber 121 directly through the ventilation channel 142. The aerosol-generating matrix in the first storage chamber 121 flows to the second storage chamber 122 through the connecting channel 141, thus balancing the pressure changes in the second storage chamber 122. This cycle continues until the aerosol-generating matrix in the first storage chamber 121 is completely consumed. Since leakage during large-cavity suction and high-temperature storage usually occurs after about 3 / 4 of the aerosol-generating matrix in the device has been consumed, the first storage chamber 121 can be used as a leakage storage space for the large cavity of the second storage chamber 122. When the temperature drops, it can effectively push the aerosol-generating matrix back into the second storage chamber 122, thereby achieving the leakage prevention function.
[0091] The distance 'a' between two adjacent baffles 1424 and the height 'b' of the main channel 1423 in the section with the baffles 1424 can be adjusted appropriately based on the viscosity of the aerosol generating matrix. Generally, the higher the viscosity of the aerosol generating matrix, the larger the dimensions of 'a' and 'b' should be. For example, for a high-viscosity aerosol generating matrix with a viscosity of 55 W CP, considering the efficiency of pressure relief and backfilling of the aerosol generating matrix, the values of 'a' and 'b' are usually around 2 mm to 3 mm.
[0092] Of course, in other embodiments, the specific shape and structure of the ventilation slot 1420 are not limited and can be adopted according to any existing ventilation structure.
[0093] In some embodiments, the housing 10 may further include a support 15 disposed within the outer casing 11. The atomizing seat 14 is supported on the support 15 and abuts against the partition wall 124 via the support 15. Furthermore, the support 15 can also be used to support the battery 30 and for mounting and securing the airflow sensor 40.
[0094] It should be noted that the electronic atomizing device 1 in this invention can be in the form of an electronic cigarette, or it can be an atomizing device used in medical or beauty fields. Furthermore, the electronic atomizing device 1 can be liquid-filled or non-liquid-filled; it can be entirely non-removable or partially removable.
[0095] The electronic atomizing device 1 can be configured for single use or reusable use. If a single-use design is adopted, the aerosol generating matrix can be directly replaced after use. If a reusable design is adopted, when the aerosol generating matrix is nearly depleted or completely used up, it can be added to the storage tank through the injection port to achieve reuse.
[0096] If the electronic atomizing device 1 adopts a partially detachable structure, it typically includes a detachably connected atomizer 100 and power supply 200. The atomizer 100 is primarily used to store the aerosol generation matrix and atomize it after power is applied. Accordingly, the atomizer 100 may include a first liquid reservoir 121, a second liquid reservoir 122, and an atomizing coil 20. The power supply 200 is primarily used to supply power to the atomizer 100 and control the entire electronic atomizing device 1 to turn on or off. Accordingly, the power supply 200 may include a control circuit, a battery 30, and an airflow sensor 40.
[0097] Figures 10 and 11 show electronic atomizing device 1 in some other embodiments of the present invention. The main difference between the electronic atomizing device 1 in this embodiment and the previous embodiment is that the electronic atomizing device 1 includes an atomizer 100 and a power supply device 200. The atomizer 100 and the power supply device 200 can be detachably connected together by means of magnetic connection, threaded connection or snap-fit connection.
[0098] In this embodiment, the atomizer 100 may include a liquid storage shell 1230, an atomizing core 20, an atomizing base 14, and a base 17. The liquid storage shell 1230 is cylindrical, and its interior is divided into a first liquid storage chamber 121 and a second liquid storage chamber 122. The first liquid storage chamber 121 and the second liquid storage chamber 122 are connected at the bottom. The partition structure inside the liquid storage shell 1230 can refer to the partition wall 124 in the previous embodiment. The communication channel for connecting the first liquid storage chamber 121 and the second liquid storage chamber 122 can be formed on the partition wall and / or on the atomizing base 14. The specific structure can be referred to the relevant description in the previous embodiment, and will not be repeated here.
[0099] A vent pipe 1240 is arranged longitudinally inside the liquid storage shell 1230. The vent pipe 1240 can be integrally formed by extending downward from the top wall of the liquid storage shell 1230, or the vent pipe 1240 and the liquid storage shell 1230 can be formed separately and then assembled together.
[0100] The atomizing seat 14 is disposed in the liquid storage shell 1230, and the atomizing seat 14 defines at least a portion of the bottom wall surface of the first liquid storage chamber 121 and at least a portion of the bottom wall surface of the second liquid storage chamber 122.
[0101] Compared with the previous embodiment, the relative positions of the atomizing core 20 and the atomizing base 14 are also different in this embodiment. In the previous embodiment, the atomizing core 20 was disposed on the upper side of the atomizing base 14, that is, the atomizing core 20 was disposed on the side of the atomizing base 14 facing the first liquid storage chamber 121 and the second liquid storage chamber 122. In this embodiment, the atomizing core 20 was disposed on the lower side of the atomizing base 14, that is, the atomizing core 20 was disposed on the side of the atomizing base 14 away from the first liquid storage chamber 121 and the second liquid storage chamber 122. Accordingly, the atomizing base 14 has a first liquid discharge channel 1461 connecting the atomizing core 20 to the first liquid storage chamber 121 and a second liquid discharge channel 1462 connecting the atomizing core 20 to the second liquid storage chamber 122.
[0102] The base 17 is disposed at the lower opening of the liquid storage shell 1230 and is used to support the atomizer coil 20 and the atomizer base 14. The base 17 and the atomizer base 14 cooperate to define a receiving space for accommodating the atomizer coil 20. The atomizer coil 20 is accommodated in the receiving space formed between the base 17 and the atomizer base 14.
[0103] The atomizer 100 also includes a ventilation channel 142 that connects the first liquid storage chamber 121 to the outside atmosphere. The ventilation channel 142 may be at least partially formed in the atomizing base 14. For example, the ventilation channel 142 may include a ventilation groove formed on the outer wall of the atomizing base 14 and / or a ventilation hole formed in the atomizing base 14.
[0104] Understandably, the above-mentioned technical features can be used in any combination without restriction.
[0105] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
