[0036] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0037] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0038] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0039] The atomization device usually consists of a liquid storage tank, an atomization assembly arranged inside the liquid storage tank, and a suction nozzle connected to the liquid storage tank. The liquid storage tank is usually provided with an atomization channel, one end of the atomization channel passes through one end of the liquid storage tank, the suction nozzle has a suction nozzle channel, the suction nozzle is installed at one end of the liquid storage tank, and the suction nozzle channel is connected to one end of the atomization channel. The atomization assembly includes an atomization tube and an atomization core, the atomization tube is connected to the atomization channel, the atomization core is installed in the atomization tube, and a liquid inlet hole is opened on the tube wall of the atomization tube, wherein the inner wall of the liquid storage tank, the outer wall of the atomization channel and the outer wall of the atomization tube enclose a liquid storage cavity for storing the atomized liquid.

[0040] The atomizer's storage chamber is already filled with atomizing liquid when the product is shipped. This atomizing liquid is supplied to the atomizer core through the liquid inlet on the atomizer tube, which then heats and atomizes the atomized liquid to produce an aerosol. During prolonged storage and transportation, the atomizer liquid is susceptible to leakage through the atomizer tube. This leaked atomized liquid can leak through the atomizer's air inlet to the exterior of the product, affecting its appearance. It can also leak through the atomizer tube onto the product's internal electronic components, causing malfunctions and posing a safety hazard.

[0041] At the same time, the atomizing liquid has a certain shelf life. If the atomizing device product that is filled with atomizing liquid during shipment is not used for a long time, the atomizing liquid will easily deteriorate during contact with the air, thereby affecting the taste of the aerosol.

[0042] In response to the above problems, the present application provides an atomizing device whose nozzle is detachable. The product is not filled with atomizing liquid when it leaves the factory. The user only needs to disassemble the nozzle and fill it with atomizing liquid when using the product, which can avoid leakage of atomizing liquid during production, transportation and storage.

[0043] This embodiment provides an atomizing device, see Figures 1-4 As shown, the atomizing device includes a nozzle 10 and a liquid storage tank 20.

[0044] A nozzle channel 110 is provided through the nozzle 10 , and a liquid injection sealing portion 111 and a pressure relief sealing portion 112 are provided at one end of the nozzle 10 .

[0045] The liquid storage tank 20 has a liquid storage chamber 21 for storing atomized liquid. A liquid storage element 211 is located within the liquid storage chamber 21. This element is typically made of a material such as fiber cotton. The atomized liquid is stored in the liquid storage element 211 through adsorption, and the atomized liquid can be atomized to produce an aerosol by heating. A connecting hole 22, a liquid injection hole 23, and a pressure relief hole 24 are provided at one end of the liquid storage tank 20. An atomization channel 25 is also located within the liquid storage chamber 21, communicating with the connecting hole 22.

[0046] Before use, the atomizing device provided in the present application can be filled with atomized liquid into the liquid storage chamber 21 through the liquid injection hole 23. During the process of filling the atomized liquid, the pressure relief hole 24 can smoothly discharge the air inside the liquid storage chamber 21 to ensure smooth filling of the atomized liquid.

[0047] like Figures 1-4 As shown, in this embodiment, one end of the suction nozzle 10 is detachably connected to one end of the liquid storage tank 20. When the suction nozzle 10 and the liquid storage tank 20 are connected as one, the suction nozzle channel 110 is connected to the connecting hole 22, the liquid injection sealing part 111 blocks the liquid injection hole 23, and the pressure relief sealing part 112 blocks the pressure relief hole 24.

[0048] The atomization device provided in this embodiment also includes an atomization assembly 30, wherein the atomization assembly 30 includes an atomization tube 31 and an atomization core 32. The atomization tube 31 is arranged inside the atomization channel 25, and the atomization core 32 is arranged inside the atomization tube 31. A liquid inlet is also provided on the atomization tube 31. The atomization core 32 is composed of a liquid guide member and a heating member. The heating member is arranged inside the liquid guide member. Part of the liquid guide member can extend to the outside of the atomization tube 31 through the liquid inlet and contact the liquid storage member 211. The atomized liquid stored in the liquid storage member 211 can be transferred to the liquid guide member, that is, the atomized liquid can be heated and atomized by the heating member to generate an aerosol. The generated aerosol is output to the outside of the nozzle 10 through the atomization channel 22 and the nozzle channel 110.

[0049] The atomizer device also includes a housing 40, with the liquid reservoir 20 disposed within it and the nozzle 10 located outside. The housing 40 also includes an air inlet 41. The other end of the atomizer tube 31 extends through the liquid reservoir 20 and communicates with the air inlet 41. During actual use, when the user inhales through the nozzle 10, external air enters the atomizer tube 31 through the air inlet 41. When the heater heats the atomized liquid, particles are generated, which mix with the external air to form an aerosol.

[0050] In the present application, during the storage and transportation period of the atomizing device after leaving the factory, the suction nozzle 10 and the liquid storage tank 20 are packaged separately, and no atomizing liquid is added to the liquid storage tank 20. Therefore, there is no problem of leakage of the atomizing device during storage and transportation. The atomizing liquid is not added to the liquid storage chamber 21 through the liquid filling hole 23 until the product is used, thereby avoiding the problem of deterioration of the atomizing liquid due to contact with the air. At the same time, fresh atomizing liquid stored in the liquid storage bottle within the shelf life can be provided.

[0051] The atomizing device provided in the present application is packaged separately with the nozzle 10 and the liquid storage tank 20 during product storage and transportation. When the atomizing device needs to be used, the atomizing liquid is added to the liquid storage chamber 21 through the liquid injection hole 23, and then one end of the nozzle 10 is connected to one end of the liquid storage chamber 21. The communicating hole 22 can be connected with the nozzle channel 110, and the liquid injection sealing part 111 blocks the liquid injection hole 23, and the pressure relief sealing part 112 blocks the pressure relief hole 24 to prevent the atomized liquid from leaking. Afterwards, after the liquid storage part 211 absorbs the atomized liquid and transmits the absorbed atomized liquid to the liquid guide part, the user can directly use the atomizing device.

[0052] In some embodiments, a blocking member 13 is further provided at the nozzle channel 110 of the nozzle 10. The blocking member 13 is detachably installed at the nozzle channel 110 to prevent foreign matter from entering the interior through the nozzle channel 110 and affecting the product performance when not in use.

[0054] like Figure 2 、 Figure 4 and Figure 6-Figure 8 As shown, the liquid injection sealing part 111 and the pressure relief sealing part 112 are both columnar structures. The liquid injection sealing part 111 can be inserted and sealed into the liquid injection hole 23, and the pressure relief sealing part 112 can be inserted and sealed into the pressure relief hole 24. There can be interference fit between the liquid injection sealing part 111 and the hole wall of the liquid injection hole 23, as well as between the pressure relief sealing part 112 and the hole wall of the pressure relief hole 24, so that the liquid injection sealing part 111 can seal the liquid injection hole 23, and the pressure relief sealing part 112 can seal the pressure relief hole 24.

[0055] like Figure 7As shown, in order to improve the sealing performance, at least one first liquid injection annular protrusion 1111 is provided on the outer periphery of the liquid injection sealing portion 111, and the at least one first liquid injection annular protrusion 1111 is sequentially arranged on the outer periphery of the liquid injection sealing portion 111 along the axial direction of the liquid injection sealing portion 111. It is a protrusion structure on the outer periphery of the liquid injection sealing portion 111 that can produce elastic deformation when squeezed, and can be interference fit with the hole wall of the liquid injection hole 23 after being inserted and sealed into the liquid injection hole 23, thereby achieving a sealing effect. Correspondingly, at least one first pressure relief annular protrusion 1121 is provided on the outer periphery of the pressure relief sealing portion 112. The at least one first pressure relief annular protrusion 1121 is sequentially arranged on the outer periphery of the pressure relief sealing portion 112 along the axial direction of the pressure relief sealing portion 112. It is a protrusion structure on the outer periphery of the pressure relief sealing portion 112 that can produce elastic deformation when squeezed. After being inserted and sealed into the pressure relief hole 24, it can have an interference fit with the hole wall of the pressure relief hole 24, thereby achieving a sealing effect.

[0056] Of course, in this embodiment, if Figure 2 、 Figure 4 as well as Figure 5 As shown, at least one second liquid injection annular protrusion 231 can be provided on the hole wall of the liquid injection hole 23, and at least one second pressure relief annular protrusion 241 can be provided on the hole wall of the pressure relief hole 24, wherein the second liquid injection annular protrusion 231 is provided on the hole wall of the liquid injection hole 23 around the axis of the liquid injection hole 23, and can generate a protrusion structure that is elastically deformed when squeezed, and the second pressure relief annular protrusion 241 is provided on the hole wall of the pressure relief hole 24 around the axis of the pressure relief hole 24, and can generate a protrusion structure that is elastically deformed when squeezed. The second liquid injection annular protrusion 231 can be deformed and interference fit with the liquid injection sealing part 111 after the liquid injection sealing part 111 is inserted into the liquid injection hole 23, and the second pressure relief annular protrusion 241 can be deformed and interference fit with the pressure relief sealing part 112 after the pressure relief sealing part 112 is inserted into the pressure relief hole 24, thereby achieving a sealing effect.

[0057] In some embodiments, a first liquid injection annular protrusion 1111 and a second pressure relief annular protrusion 1121 may be provided only on the periphery of the liquid injection sealing portion 111 and the pressure relief sealing portion 112, respectively; or a second liquid injection annular protrusion 231 and a second pressure relief annular protrusion 241 may be provided only on the hole wall of the liquid injection hole 23 and the hole wall of the pressure relief hole 24, respectively, both of which can achieve a sealing effect.

[0058] Of course, a first liquid injection annular protrusion 1111 and a second pressure relief annular protrusion 1121 may be respectively provided on the periphery of the liquid injection sealing portion 111 and the pressure relief sealing portion 112, and a second liquid injection annular protrusion 231 and a second pressure relief annular protrusion 241 may be respectively provided on the hole wall of the liquid injection hole 23 and the hole wall of the pressure relief hole 24, so as to achieve the same sealing effect.

[0059] See also Figure 2 and Figure 4As shown, the liquid storage tank 20 includes a tank body 26 and a first sealing member 27. A first mounting port 261 is provided at one end of the tank body 26. The first sealing member 27 is sealed and installed at the first mounting port 261. The connecting hole 22, the liquid injection hole 23 and the pressure relief hole 24 are arranged through the first sealing member 27.

[0060] In some embodiments, the liquid storage tank 20 also includes a second sealing member 28, and a second mounting port 262 is provided at the other end of the tank body 26. The second sealing member 28 is sealingly installed at the second mounting port 262. The first sealing member 27, the second sealing member 28 and the tank body 26 enclose a liquid storage cavity 21, and the atomization channel 22 is provided on the side of the first sealing member 27 facing the second sealing member 28. The liquid storage tank 26 is combined with the structure of the split combination of the tank body 26, the first sealing member 27 and the second sealing member 28, which can simplify the manufacturing steps of the liquid storage tank 26 and thereby reduce the difficulty of product manufacturing.

[0061] The first sealing member 27 and the second sealing member 28 are both made of materials such as silicone. After the first sealing member 27 and the second sealing member 28 are respectively installed at the first installation opening 261 and the second installation opening 262 at both ends of the warehouse body 26, the first installation opening 261 and the second installation opening 262 at both ends of the warehouse body 26 can be sealed.

[0062] During the use of the atomizer, the generated aerosol is output through the nozzle channel 110. During the aerosol output process, due to the long distance of the nozzle channel 110 for transmitting the aerosol, the aerosol is easily condensed due to temperature changes and forms condensate. The condensate can flow back into the atomization channel 22 through the nozzle channel 110. In order to prevent the condensate from flowing back and affecting the use of the atomizer core 32, see Figure 2 、 Figure 4 as well as Figure 7-Figure 9 As shown, the atomization device provided in this embodiment also includes a liquid absorption member 12. The liquid absorption member 12 is arranged at one end of the suction nozzle 10, so that the liquid absorption member 12 can be located between the suction nozzle 10 and the liquid storage tank 20. The liquid absorption member 12 is made of fiber cotton material, which can absorb condensed liquid by adsorption to prevent the condensed liquid from flowing back.

[0063] When the adsorption capacity of the liquid absorbing member 12 reaches saturation, if the user continues to inhale through the mouthpiece 10, part of the condensed liquid may be discharged through the mouthpiece channel 110, thereby affecting the taste of the aerosol. Figure 4 and Figure 5 As shown, at least one liquid guide groove 221 is provided on the side of the first sealing member 27 facing away from the second sealing member 28. The at least one liquid guide groove 221 is connected to the connecting hole 22, and the refluxed condensate can be guided into the connecting hole 22 and absorbed by the liquid storage member 21 through the connecting hole 22, the atomization channel 25, and the atomization tube 31.

[0064] In particular, the liquid absorbing member 12 can absorb most of the condensed liquid, while only a small portion of the condensed liquid flows back to the communicating hole 22 through the liquid guiding groove 221 and is absorbed by the liquid storage member 21 .

[0065] In this embodiment, a plurality of liquid guiding grooves 221 are provided. The plurality of liquid guiding grooves 221 are arranged in a manner of surrounding the communication hole 22 , and the liquid guiding grooves 221 are preferably inclined groove-shaped structures for easy liquid conduction.

The connecting hole 22, the liquid injection hole 23 and the pressure relief hole 24 are all provided at the bottom of the slot 271, and the liquid guide groove 221 is provided at the bottom of the slot 271.

[0067] When connecting one end of the nozzle 10 to one end of the liquid storage tank 20, in order to achieve a quick-release connection, a snap-on connection is used in this embodiment. Figure 5-Figure 9 As shown, a first clamping portion 272 is provided on the side wall of the slot 271, and a second clamping portion 113 is provided on the outer periphery of one end of the suction nozzle 10. One end of the suction nozzle 10 is inserted into the slot 271, and the first clamping portion 271 is clamped and connected with the second clamping portion 113, thereby detachably connecting the suction nozzle 10 to the liquid storage tank 20.

[0068] Of course, in other embodiments, one end of the suction nozzle 10 and one end of the liquid storage tank 20 can also be quickly connected by means of magnetic connection, interference fit, clamp connection, etc. The specific connection can be selected according to actual needs and is not limited here.

[0069] The connecting hole 22, the liquid injection hole 23 and the pressure relief hole 24 are all arranged at the bottom of the slot 271, and the liquid injection sealing part 111 and the pressure relief sealing part 112 are both arranged at one end of the suction nozzle 10, that is, after one end of the suction nozzle 10 is inserted into the slot 271, the suction nozzle channel 110 can be connected with the connecting hole 22, the liquid injection sealing part 111 can be inserted into the liquid injection hole 23, and the pressure relief sealing part 112 can be inserted into the pressure relief hole 24.

[0070] After one end of the nozzle 10 is inserted into the slot 271, there is also a certain gap between the nozzle 10 and the inner wall of the slot 271. Figure 4 and Figure 5 As shown, at least one slot annular protrusion 273 is provided on the inner side wall of the slot 271. The slot annular protrusion 273 is arranged around the inner side wall of the slot 271 to cooperate with the outer periphery of one end of the suction nozzle 10 for sealing, thereby sealing the gap between the suction nozzle 10 and the slot 271 to further prevent leakage of the atomized liquid.

[0071] See also Figure 7 and Figure 9 As shown, a mounting groove 14 is provided at one end of the suction nozzle 10 . The mounting groove 14 is recessed from one end of the suction nozzle 10 , wherein the liquid absorbing member 12 is fixed in the mounting groove 14 .

[0072] In one embodiment of the present application, the liquid absorbing member 12 is provided with a liquid absorbing through hole 120 , which is connected to the nozzle channel 110 , thereby ensuring smooth passage of aerosol and airflow.

For example, the energy supply unit 50 uses a lithium battery cell, and a charging interface 51 is further provided on the housing 40 to replenish the energy supply unit 50 with electricity.

[0076] To sum up, in the atomizing device provided by the present application, the suction nozzle and the liquid storage tank are packaged separately during the storage and transportation period after the atomizing device leaves the factory, and the liquid storage tank is not filled with atomizing liquid. Therefore, there is no problem of leakage of the atomizing device during storage and transportation. The atomizing liquid is not added to the liquid storage cavity through the liquid filling hole until the product is in use, thereby avoiding the problem of deterioration of the atomizing liquid due to contact with the air. At the same time, fresh atomizing liquid stored in the liquid storage bottle within the shelf life can be provided.
