[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] After long-term research, the inventors of this application have found that: if the liquid storage component has a uniform density, the liquid conductivity of each position of the liquid storage component is the same; the farther the liquid storage component is from the atomizing component, the less likely it is that the atomizing medium stored there will be introduced into the atomizing component. If a low-density liquid storage component is used alone, the adsorption force of the liquid storage component on the atomizing medium will be reduced, causing the atomizing medium in the atomizing component to be oversaturated, causing the atomizer to leak during the suction process. On the contrary, if a high-density liquid storage component is used alone, the atomizing medium at a position far away from the atomizing component (the distal end) will be difficult to be introduced into the atomizing component, resulting in a low utilization rate of the atomizing medium.

[0033] To this end, an embodiment of the present application provides a nebulizer, wherein the liquid storage component of the nebulizer solves the problem that the atomizing medium at the far end of the liquid storage component is difficult to reach the atomizing medium and cannot be atomized by virtue of the difference in fluidity of the liquid inside the liquid storage component due to the different density of the fiber body of the liquid storage component, and solves the problem that only using a low-density liquid storage part leads to liquid leakage during suction and transportation. The liquid storage component of the nebulizer can supply liquid to the atomizing component more evenly, so as to reduce the residual amount of the atomizing medium in the liquid storage component, and reduce pollution and waste of the atomizing medium.

[0034] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0035] See also Figure 1 , Figure 1 A vertical cross-sectional view of an electronic atomization device provided in one embodiment of the present application; in this embodiment, an electronic atomization device 100 is provided, which can be used to atomize an atomization medium to form an aerosol for a user to inhale. The atomization medium can be a plant grass leaf matrix, a paste matrix, or a liquid matrix such as oils or liquid medicine with added aroma components. Specifically, the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20.

[0036] The atomizer 10 can be used in different fields, such as medical atomization, leisure smoking or hairdressing. The atomizer 10 is specifically used to heat and atomize the atomization medium to form an aerosol when powered on. Specifically, the atomizer 10 can be the atomizer 10 involved in any of the following embodiments, and its specific structure and function can refer to the description of the specific structure and function of the atomizer 10 in the following embodiments, and can achieve the same or similar technical effects, which can be specifically referred to below.

[0037] The power supply assembly 20 is electrically connected to the atomizer 10 for supplying power to the atomizer 10. The atomizer 10 and the power supply assembly 20 may be detachably connected to facilitate replacement of the atomizer 10 and improve the utilization of the power supply assembly 20. Of course, in other embodiments, the power supply assembly 20 and the atomizer 10 may also be integrally arranged, and the present application does not limit this.

[0038] The power supply assembly 20 may include a battery, a bracket, an airflow sensor (not shown), a control circuit board (not shown), etc. The battery is specifically used to power the atomizer 10, and the airflow sensor is used to detect the user's inhalation state and transmit the detection result to the control circuit board to control the start and stop of the atomizer 10. The battery, the airflow sensor (not shown), the control circuit board (not shown), etc. are all arranged on the bracket, and the bracket supports them.

[0039] In this embodiment, a housing 30 is provided outside the power assembly 20 and the atomizer 10 to connect and protect the power assembly 20 and the atomizer 10. The housing 30 defines a nozzle through which the user inhales the aerosol. The housing 30, the power assembly 20, and the atomizer 10 can be connected by means of a snap connection, a threaded connection, etc., which is not limited in this application.

[0040] See also Figure 2 , Figure 2 This is an embodiment of the present application Figure 1 A schematic diagram of the partial structure of an atomizer in the electronic atomization device shown; the atomizer 10 includes an atomization component 1 and a liquid storage component 2.

[0041] The atomizing assembly 1 is used to atomize the atomizing medium to form an aerosol. The liquid storage assembly 2 is used to supply liquid to the atomizing assembly 1; and the liquid storage assembly 2 includes a first liquid storage member 21 and a second liquid storage member 22; the first liquid storage member 21 and the second liquid storage member 22 are respectively arranged around the circumferential direction of the atomizing assembly 1, and the second liquid storage member 22 is located on the side of the first liquid storage member 21 away from the atomizing assembly 1; wherein the density of the first liquid storage member 21 is greater than the density of the second liquid storage member 22, so that the liquid absorption capacity of the first liquid storage member 21 is greater than the liquid absorption capacity of the second liquid storage member 22. In this way, during the liquid supply process, the atomizing medium in the liquid storage assembly 2 will be enriched from the low-density second liquid storage member 22 to the high-density first liquid storage member 21, so that the liquid storage assembly 2 can supply liquid to the atomizing assembly 1 more evenly, so as to reduce the residual amount of the atomizing medium in the liquid storage assembly 2, reduce pollution and waste of the atomizing medium.

[0042] The first liquid storage member 21 and / or the second liquid storage member 22 may be liquid storage cotton of different densities.

[0043] According to experimental verification by the inventor, if the ratio of the density of the second liquid storage component 22 to the density of the first liquid storage component 21 is less than 0.3, it will lead to increased production costs and manufacturing difficulties. If the ratio of the density of the second liquid storage component 22 to the density of the first liquid storage component 21 is greater than 0.8, the density difference between the second liquid storage component 22 and the first liquid storage component 21 is too small, the enrichment effect of the liquid from the second liquid storage component 22 to the first liquid storage component 21 is not obvious, and the atomized medium stored in the liquid storage component 2 is difficult to be fully released, resulting in an excessive amount of atomized medium remaining in the liquid storage component 2, and the residual amount of atomized medium is too large, resulting in a waste of resources. Therefore, in some embodiments, the ratio of the density of the second liquid storage component 22 to the density of the first liquid storage component 21 is greater than or equal to 0.3 and less than or equal to 0.8. For example, the ratio can be 0.3, 0.4, 0.5, 0.6, 0.7 or 0.8.

[0044] The density of the first liquid storage member 21 may be 0.07 to 0.2 g / cm 3For example, the density of the first liquid storage member 21 may be 0.07 g / cm 3 , 0.09g / cm 3 , 0.1g / cm 3 , 0.15g / cm 3 or 0.2g / cm 3 When the density of the first liquid storage member 21 is less than 0.05 g / cm 3 When the density of the first liquid storage member 21 is greater than 0.1 g / cm 3 , making it difficult.

[0045] The density of the second liquid storage member 22 may be 0.03-0.07 g / cm 3 For example, the density of the second liquid storage member 22 may be 0.03 g / cm 3 , 0.05g / cm 3 , 0.06g / cm 3 or 0.07g / cm 3 When the density of the second liquid storage member 22 is less than 0.03 g / cm 3 When the density of the second liquid storage member 22 is greater than 0.77 g / cm 3 The second liquid storage component 22 has too strong a liquid absorption capacity. When the liquid is released, it is difficult for the liquid to be enriched from the second liquid storage component 22 to the first liquid storage component 21, resulting in too much residual atomized medium in the liquid storage component 2, leading to a waste of resources.

[0046] In one embodiment, in combination Figure 2 and Figure 3 , Figure 3 The schematic diagram of the overall structure of the atomizer provided in one embodiment of the present application. The first liquid storage part 21 and the second liquid storage part 22 are both in a closed loop shape, and the atomizing assembly 1 is arranged on the inner side of the first liquid storage part 21; the second liquid storage part 22 is sleeved on the outer wall surface of the first liquid storage part 21. Specifically, the second liquid storage part 22 and the first liquid storage part 21 are interference fit to ensure that the position where the second liquid storage part 22 contacts the first liquid storage part 21, and the atomized medium in the second liquid storage part 22 can be well diverted to the first liquid storage part 21, reducing the risk of leakage of the atomized medium at the position where the two contact.

[0047] The cross section of the first liquid storage member 21 can be a regular circular ring. The cross section of the second liquid storage member 22 can be set according to the shape of the actual atomizer 10, such as a circular ring, an elliptical ring or an irregular circular ring. Along the axial direction Y of the liquid storage component 2, the length of the first liquid storage member 21 and the length of the second liquid storage member 22 can be the same, so as to facilitate preparation and facilitate the atomization medium in the second liquid storage member 22 to be diverted to the first liquid storage member 21, thereby reducing leakage.

[0048] The thickness of the first liquid storage member 21 and the thickness of the second liquid storage member 22 can be set according to actual conditions, as long as the atomized medium in the second liquid storage member 22 can be well guided to the first liquid storage member 21 .

[0049] In one embodiment, see Figure 2 The atomizer 10 further includes a base 3, the base 3 having a bearing surface, and the liquid storage assembly 2 is disposed on the bearing surface of the base 3. In some specific embodiments, the bearing surface of the base 3 has a plurality of liquid storage tanks 31, the liquid storage assembly 2 is connected to the plurality of liquid storage tanks 31, and the liquid storage tanks 31 are used to recover the atomized medium flowing out of the liquid storage assembly 2, which helps to prevent the atomized medium from leaking out of the base 3 and contaminating other devices.

[0050] The liquid storage tanks 31 can be interconnected so that the atomized medium in the liquid storage tanks 31 can flow to each other, preventing leakage due to some liquid storage tanks 31 being full of atomized medium and some liquid storage tanks 31 having only a small amount of atomized medium. The base 3 can be made of materials such as silicone rubber and fluororubber.

[0051] In this embodiment, combined Figure 3 The outer wall surface of the second liquid storage member 22 may also be provided with a liquid guide groove 221, which may extend along the axial direction Y of the second liquid storage member 22 and communicate with a plurality of liquid storage grooves 31. In this way, the liquid storage assembly 2 may cause the atomized medium in the liquid storage groove 31 to flow back to the liquid storage assembly 2 through the liquid guide groove 221 through the capillary force of the guide vane groove for atomization, thereby improving the utilization rate of the atomized medium.

[0052] The number of the liquid-conducting grooves 221 may be multiple, and the multiple liquid-conducting grooves 221 may be arranged at intervals along the circumferential direction of the second liquid storage member 22. The number of the liquid-conducting grooves 221 may specifically be two.

[0053] See also Figure 4 , Figure 4 A schematic diagram of the assembly process of the first liquid storage component and the second liquid storage component is provided for one embodiment of the present application; during the assembly process, the atomizer assembly 1 and the first liquid storage component 21 are first fixed to the base 3, and then the second liquid storage component 22 is wrapped around the first liquid storage component 21 by interference fit.

[0054] In some embodiments, see Figure 2 and Figure 3 The atomizer 10 further includes a first sleeve 4 and a second sleeve 5. The first sleeve 4 is disposed on the side of the atomizer assembly 1 away from the base 3, and defines an air outlet channel, through which the aerosol formed by atomization of the atomizer assembly 1 flows out to the mouthpiece for inhalation by the user. The second sleeve 5 is disposed on the base 3, and is sleeved on the outside of the first sleeve 4 and the atomizer assembly 1, and cooperates with the first sleeve 4 to form a clamping cavity. The first liquid storage member 21 and the second liquid storage member 22 are sequentially disposed around the first sleeve 4 and clamped in the clamping cavity; to prevent the liquid storage assembly 2 from leaking.

[0055] The first sleeve 4 and / or the second sleeve 5 may be a hollow cylindrical structure. The first liquid storage member 21 and the second liquid storage member 22 are arranged around the first sleeve 4 and the atomizing assembly 1, and the first liquid storage member 21 is arranged in contact with the outer wall surface of the first sleeve 4. The first sleeve 4 may be a glass fiber tube, and the second sleeve 5 may be a liquid storage tube.

[0056] In some embodiments, see Figure 5 and Figure 6 , Figure 5 A schematic diagram of the overall structure of an atomizer provided in another embodiment of the present application; Figure 6 An embodiment of the present application provides Figure 2 The AA section view of the atomizer shown; the atomizer 10 also includes an end cover 6, which is disposed on the end of the second sleeve 5 away from the base 3, and cooperates with the base 3 to clamp the liquid storage component 2 along the axial direction Y of the liquid storage component 2; and the end cover 6 has an air outlet; the air outlet is connected to the air outlet channel.

[0057] The end cap 6 can be specifically threadedly connected with the second sleeve 5, and cooperate with the base 3 and the second sleeve 5 to form a sealed cavity, and the liquid storage component 2 is arranged in the sealed cavity to reduce the risk of leakage. At the same time, by clamping the liquid storage component 2 along the axial direction Y of the liquid storage component 2 by the base 3 and the end cap 6, on the one hand, it is conducive to the miniaturization of the atomizer 10; on the other hand, it can prevent the liquid storage component 2 from moving back and forth in the sealed cavity, and the atomized medium in the liquid storage tank 31 of the base 3 cannot effectively flow back to the liquid storage component 2, resulting in waste of atomized medium. The material of the end cap 6 can be the same as that of the base 3.

[0058] Combination Figure 2 The atomizing assembly 1 includes a heating seat 11, a liquid guide 12, a heating element 13, a heating lead 14 and a fixing element 15. The heating seat 11 is arranged on the base 3. The heating seat 11 can be a hollow cylindrical structure. The heating seat 11 has an annular side wall. A plurality of liquid guide holes are opened on the annular side wall. The shape of the liquid guide holes can be rectangular or circular.

[0059] The liquid guide 12 is arranged on the heating seat 11, specifically on the inner surface of the hollow cylinder of the heating seat 11, and the liquid guide 12 can be connected with the atomized medium of the liquid storage assembly 2 through the liquid guide hole. The liquid guide 12 is preferably arranged in multiple layers, and a plurality of liquid guides 12 are stacked to form an arc-shaped liquid guide 12, preferably a superior arc structure, to enhance the liquid guide efficiency of the liquid guide 12.

[0060] The liquid guide member 12 can extend from one of the liquid guide holes of the heating seat 11 and contact the first liquid storage member 21, so that the liquid guide member 12 absorbs the atomized medium and better guides the atomized medium to the heating element 13, thereby improving the liquid guide effect. In this embodiment, the liquid guide member 12 can be a liquid guide cotton, so that the liquid guide member 12 can absorb more atomized medium to guide it to the heating element 13.

[0061] The heating element 13 is arranged on the liquid guiding element 12, specifically on the inner surface of the liquid guiding element 12, and is arranged in close contact with the liquid guiding element 12, and is used to heat the atomized medium to generate an aerosol. In this embodiment, the heating element 13 can be a heating net or a heating wire, etc. A heating lead 14 is arranged at one end of the heating element 13 close to the power supply component 20, and the heating lead 14 is electrically connected to the heating element 13, and the heating lead 14 extends to the power supply component 20, and is electrically connected to the power supply component 20, so that the power supply component 20 can supply power to the heating element 13, so that the heating element 13 can heat the atomized medium to generate an aerosol for the user to inhale.

[0062] In one embodiment, the fixing member 15 is disposed in the heating seat 11, specifically, at one end of the liquid guide member 12 away from the first sleeve 4. The outer wall of the fixing member 15 has a plurality of flanges, and the flanges abut against the inner surface of the heating seat 11. The heating lead 14 is riveted to the heating seat 11 through the fixing member 15, and extends from the heating seat 11 through the gap between adjacent flanges, so that the adjacent flanges and the heating seat 11 can limit the heating lead 14 in the horizontal direction. Furthermore, the adjacent flanges and the inner wall of the heating seat 11 can be completely fitted with the heating lead 14, thereby improving the limiting effect.

[0063] The fixing member 15 may be in a hollow cylindrical shape and may be made of insulating materials such as plastic and ceramic to prevent a short circuit between the fixing member 15 and the heating lead 14 .

[0064] The atomizer 10 provided in this embodiment includes an atomizing assembly 1 and a liquid storage assembly 2; the atomizing assembly 1 is used to atomize the atomizing medium to form an aerosol; the liquid storage assembly 2 is used to supply liquid to the atomizing assembly 1; and the liquid storage assembly 2 includes a first liquid storage member 21 and a second liquid storage member 22; the first liquid storage member 21 and the second liquid storage member 22 are respectively arranged around the circumferential direction of the atomizing assembly 1, and the second liquid storage member 22 is located on the side of the first liquid storage member 21 away from the atomizing assembly 1; the density of the first liquid storage member 21 is greater than the density of the second liquid storage member 22, so that the liquid absorption capacity of the first liquid storage member 21 is greater than the liquid absorption capacity of the second liquid storage member 22. In this way, during the liquid supply process, the atomizing medium in the liquid storage assembly 2 will be enriched from the low-density second liquid storage member 22 to the high-density first liquid storage member 21, so that the liquid storage assembly 2 can supply liquid to the atomizing assembly 1 more evenly, so as to reduce the residual amount of the atomizing medium in the liquid storage assembly 2, reduce pollution and waste of the atomizing medium.
