Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomization device and atomization equipment. Background Art

[0002] The aroma of the atomizer will be significantly attenuated in the latter part of the suction. One of the reasons is that the aroma substances (ester substances) inside the atomized liquid have a volatilization temperature of 70-150°C. During the use of the atomizer, the aerosol temperature after continuous atomization is relatively high, usually around 100°C. The aroma substances inside the atomized liquid, especially the atomized liquid close to the high-temperature aerosol, are easy to volatilize. Therefore, when the atomizer is sucked to the latter part, the aroma substances inside the atomized liquid will be completely volatilized, resulting in a significant attenuation of the aroma.

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] This application provides an atomizing device. In one embodiment, please refer to Figures 1 to 3 , Figure 1 is a three-dimensional schematic diagram of an embodiment of the atomization device provided by this application, Figure 2 yes Figure 1 Axial cross-sectional schematic diagram of the atomization device, Figure 3 yes Figure 1 The schematic diagram of the disassembled structure of the atomizing device is shown in FIG. 1 , wherein the atomizing device 100 includes a shell 110, an insulating sleeve assembly 121 and an elastic sleeve 122. The inner wall of the shell 110 is defined by a liquid storage chamber 111 for storing atomized liquid. The shell 110 includes a vent pipe 112. The liquid storage chamber 111 is arranged around the vent pipe 112. The atomized liquid in the liquid storage chamber 111 can be heated and atomized, and the atomized gas can enter the vent pipe 112 for the user to inhale. The insulating sleeve assembly 121 is located in the liquid storage chamber 111 and is sleeved on the outside of the vent pipe 112. The elastic sleeve 122 is sleeved on the outside of the insulating sleeve assembly 121 and elastically presses the insulating sleeve assembly 121 onto the vent pipe 112.

[0052] The atomizing device 100 provided in the present application has a high temperature of the ventilation tube 112 due to the circulation of the high-temperature gas after atomization in the ventilation tube 112. If the atomized liquid in the liquid storage chamber 111 is in direct contact with the ventilation tube 112, the temperature of the atomized liquid will be high. The present application reduces the heat transfer from the ventilation tube 112 to the atomized liquid, reduces the increase in the temperature of the atomized liquid, and thus reduces the volatilization of aroma substances in the atomized liquid by arranging the insulating sleeve assembly 121 outside the ventilation tube 112 to isolate the direct contact between the ventilation tube 112 and the atomized liquid in the liquid storage chamber 111, thereby reducing the heat transfer from the ventilation tube 112 to the atomized liquid, reducing the increase in the temperature of the atomized liquid, and thus reducing the volatilization of aroma substances in the atomized liquid. The elastic sleeve 122 can elastically press the insulating sleeve assembly 121 onto the vent pipe 112 through its own elasticity, thereby preventing the insulating sleeve assembly 121 from falling from the vent pipe 112, and because the elastic sleeve 122 is sleeved on the outside of the insulating sleeve assembly 121, the elastic sleeve 122 can also play a heat-insulating effect, further increasing the heat-insulating effect of the atomizing device 100 of the present application on the atomized liquid in the liquid storage chamber 111.

[0053] See again Figure 2 , and see also Figure 4 and Figure 5 , Figure 4 yes Figure 2 and Figure 3 A schematic diagram of the three-dimensional structure of the shell in the atomization device, Figure 5 yes Figure 4 The cross-sectional perspective schematic diagram of the shell, specifically, the shell 110 includes a main body tube 113 and the above-mentioned ventilation tube 112, the ventilation tube 112 is located inside the main body tube 113, both ends of the ventilation tube 112 are opened for the circulation of atomizing gas, and the main body tube 113 and the ventilation tube 112 are spaced apart in the radial direction of the atomizing device 100.

[0054] The atomizing device 100 further includes a nozzle 114, which is located at one end of the atomizing device 100 in the axial direction. The nozzle 114 can be integrally formed with the main tube 113, or can be separately provided with the main tube 113 and fixed to one end of the main tube 113. Figure 2 as well as Figure 4 and Figure 5 The suction nozzle 114 is shown as being integrally formed with the main body tube 113 , and the suction nozzle 114 is formed by bending one end of the main body tube 113 toward one end of the vent tube 112 and then sealing and connecting them.

[0055] One end of the main tube 113 away from the suction nozzle 114 is open and has a certain distance from the end of the ventilation tube 112 away from the suction nozzle 114 in the axial direction of the atomization device 100. The open end of the main tube 113 can be used for other components of the atomization device 100 (for example, it can be an atomization component for heating and atomizing the atomized liquid, or a liquid absorption component for adsorbing the liquid after the atomized gas is condensed, etc.) to be installed in the shell 110.

[0056] In addition, an air flow channel 1140 is provided in the mouthpiece 114, and the air flow channel 1140 is connected to the ventilation tube 112. Therefore, when the user inhales through the mouthpiece 114, the air flow in the ventilation tube 112 can enter the air flow channel 1140 of the mouthpiece 114 and be inhaled by the user.

[0057] The vent pipe 112 can be integrally connected to the suction nozzle 114. Specifically, the vent pipe 112 can be integrally connected to the air flow channel 1140 of the suction nozzle 114. Further, the vent pipe 112, the air flow channel 1140 of the suction nozzle 114 and the main body pipe 113 can be integrally formed. Figure 5 The structure shown.

[0058] The vent tube 112 can also be separated from the air flow channel 1140 of the suction nozzle portion 114 in the axial direction of the atomizer device 100, and the suction nozzle portion 114 is located on the side of the liquid storage chamber 111 in the axial direction of the atomizer device 100. In this case, the air flow in the vent tube 112 can still enter the air flow channel 1140 of the suction nozzle portion 114, but because the vent tube 112 is separated from the air flow channel 1140 of the suction nozzle portion 114, it is necessary to provide a sealing element (not shown in the figure) between one end of the vent tube 112 and one end of the air flow channel 1140 of the suction nozzle portion 114 to prevent the atomized liquid in the liquid storage chamber 111 from entering the vent tube 112 or the air flow channel 1140 of the suction nozzle portion 114 through the gap between the vent tube 112 and the air flow channel 1140 of the suction nozzle portion 114.

[0059] The sealing element can be tightly fitted to the inner wall of the main tube 113. The sealing element separates the vent tube 112 from the mouthpiece 114 in the axial direction of the atomizing device 100, so that in the axial direction of the atomizing device 100, the mouthpiece 114 is located on one side of the sealing element, and the vent tube 112 and the liquid storage chamber 111 are located on the other side of the sealing element. The sealing element can be made of a material with a certain elasticity, such as silicone, to achieve a sealing effect. An airway is axially penetrated by the sealing element. The airflow channel 1140 of the vent tube 112 and the mouthpiece 114 are respectively connected to the airway in the sealing element. Therefore, the airflow in the vent tube 112 can enter the airflow channel 1140 of the mouthpiece 114 via the airway in the sealing element.

[0060] The vent tube 112 may be a metal vent tube or a plastic vent tube, or may be made of other dense materials other than metal and plastic to prevent the atomized liquid in the liquid storage chamber 111 from entering the vent tube 112 .

[0061] The heat-insulating sleeve assembly 121 can be made of hard materials such as aerogel and other materials with good heat-insulating effects. The elastic sleeve 122 can be made of silicone or polyethylene (PE), or other materials with elasticity and good heat-insulating effects.

[0062] According to the principle of heat insulation by the insulating sleeve assembly 121 of the present application, it can be understood that the insulating sleeve assembly 121 should cover the entire length of the vent tube 112 as much as possible to avoid direct contact between the vent tube 112 and the atomized liquid in the liquid storage chamber 111 as much as possible. In fact, since the capacity of the atomized liquid injected into the liquid storage chamber 111 is usually certain and the maximum injection volume should not be greater than the internationally specified capacity, such as 2ml, 5ml, 10ml, the capacity of the injection volume in the liquid storage chamber 111 is also limited, that is, after the atomized liquid is injected into the liquid storage chamber 111, the atomized liquid has a certain height in the liquid storage chamber 111. Therefore, the length of the insulating sleeve assembly 121 in the present application should be at least greater than the height of the atomized liquid in the liquid storage chamber 111.

[0063] See again Figure 2 , and also see Figure 6 , Figure 6 yes Figure 2 Schematic diagram of the structure of the heat-insulating sleeve assembly and the elastic sleeve in the atomization device ( Figure 6 The left part is an axial cross-sectional view, and the right part is a disassembled three-dimensional view). In one embodiment, the thermal insulation sleeve assembly 121 includes a first rigid thermal insulation sleeve 1211 and / or a second rigid thermal insulation sleeve 1212. The first rigid thermal insulation sleeve 1211 is a porous thermal insulation sleeve, and the second rigid thermal insulation sleeve 1212 has at least one thermal insulation cavity provided in its wall.

[0064] The meaning that the thermal insulation sleeve assembly 121 includes the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 is that the thermal insulation sleeve assembly 121 may include the first rigid thermal insulation sleeve 1211 but not the second rigid thermal insulation sleeve 1212, or the thermal insulation sleeve assembly 121 may include the second rigid thermal insulation sleeve 1212 but not the first rigid thermal insulation sleeve 1211, or the thermal insulation sleeve assembly 121 may include the first rigid thermal insulation sleeve 1211 and the second rigid thermal insulation sleeve 1212. Figure 6 and Figure 7 The heat-insulating sleeve assembly 121 includes a first rigid heat-insulating sleeve 1211 and a second rigid heat-insulating sleeve 1212 ; Figure 8 The figure shows a case where the thermal insulation sleeve assembly 121 includes a first rigid thermal insulation sleeve 1211 but does not include a second rigid thermal insulation sleeve 1212; Figure 9 The case where the thermal insulation sleeve assembly 121 includes the second rigid thermal insulation sleeve 1212 but does not include the first rigid thermal insulation sleeve 1211 is shown.

[0065] When the thermal insulation sleeve assembly 121 includes a first rigid thermal insulation sleeve 1211 and a second rigid thermal insulation sleeve 1212, the position distribution between the first rigid thermal insulation sleeve 1211 and the second rigid thermal insulation sleeve 1212 can be in various situations: the second rigid thermal insulation sleeve 1212 can be sleeved on the outside of the first rigid thermal insulation sleeve 1211 ( Figure 2 and Figure 6 As shown), or the first rigid heat-insulating sleeve 1211 is sleeved on the outside of the second rigid heat-insulating sleeve 1212 ( Figure 7 As shown), the first hard thermal insulation sleeve 1211 and the second hard thermal insulation sleeve 1212 may also be distributed along the axial direction of the atomization device 100.

[0066] The first hard thermal insulation sleeve 1211 can be a thermal insulation sleeve made of a porous material. Since the porous material has many pores and holes inside, it can dissipate the heat of the atomized liquid transferred from the ventilation tube 112 to the liquid storage chamber 111 to a great extent, and has a good thermal insulation effect. For example, the porous material can be aerogel or other porous materials.

[0067] An insulating cavity can be provided in the tube wall of the second rigid thermal insulation sleeve 1212. The thermal conductivity of the insulating cavity is small, and thus it can also achieve a good thermal insulation effect. This application does not specifically limit the shape and number of the insulating cavity, but it can be inferred that the larger the volume occupied by the insulating cavity, the better the thermal insulation effect. In some embodiments, the insulating cavity can also be filled with a cooling material to further improve the thermal insulation effect. In addition, the insulating cavity can also be vacuumed. The higher the vacuum degree in the insulating cavity, the better the thermal insulation effect. In other words, the second rigid thermal insulation sleeve 1212 is a vacuum insulating sleeve.

[0068] See again Figure 2 In one embodiment, the two ends of the elastic sleeve 122 respectively wrap the two ends of the first rigid thermal insulation sleeve 1211 to isolate the first rigid thermal insulation sleeve 1211 from the atomized liquid in the liquid storage chamber 111. Since the first rigid thermal insulation sleeve 1211 is made of a porous material, when the porous material contacts the atomized liquid, the porous material will absorb the atomized liquid. Therefore, in this embodiment, the two ends of the elastic sleeve 122 respectively wrap the two ends of the first rigid thermal insulation sleeve 1211, which can prevent the two ends of the first rigid thermal insulation sleeve 1211 from absorbing the atomized liquid. Since the elastic sleeve 122 itself is elastic, the length of the elastic sleeve 122 can be set to be longer than the length of the first rigid thermal insulation sleeve 1211. When the elastic sleeve 122 is sleeved outside the first rigid thermal insulation sleeve 1211, the two ends of the elastic sleeve 122 can elastically abut the outer wall of the ventilation pipe 112, thereby achieving that the two ends of the elastic sleeve 122 respectively wrap the two ends of the first rigid thermal insulation sleeve 1211. Figure 2 In the illustrated embodiment, both ends of the elastic sleeve 122 respectively wrap around both ends of the first rigid thermal insulation sleeve 1211 and the second rigid thermal insulation sleeve 1212 .

[0069] See again Figure 6 The first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 is provided with an assembly notch 1210, and the assembly notch 1210 passes through both ends of the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 along the axial direction of the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212, so that the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 constitute a non-closed sleeve. When the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 are made of a rigid material and have an axially extending notch 1210 therethrough, the first rigid thermal insulation sleeve 1211 and / or the second rigid thermal insulation sleeve 1212 can be slightly deformed during installation to more easily fit over the vent pipe 112. Preferably, both the first rigid thermal insulation sleeve 1211 and the second rigid thermal insulation sleeve 1212 have notches 1210. When actually installing the thermal insulation sleeve assembly 121, the first rigid thermal insulation sleeve 1211, the second rigid thermal insulation sleeve 1212, and the elastic sleeve 122 can be assembled into the thermal insulation sleeve assembly 121, and then the thermal insulation sleeve assembly 121 can be fitted as a whole over the vent pipe 112, making installation more convenient and quick.

[0070] See again Figure 2In one embodiment, the atomizing device 100 further includes an atomizing assembly 130 located inside the shell 110. The atomizing assembly 130 is located on one side of the liquid storage chamber 111 in the axial direction of the atomizing device 100. The atomizing assembly 130 is used to heat and atomize the atomized liquid. The atomized gas after heating and atomization (for example, an aerosol) can enter the ventilation tube 112 and be inhaled by the user.

[0071] Specifically, please combine Figure 2 as well as Figures 10 to 13 , Figure 10 yes Figure 2 and Figure 3 A three-dimensional schematic diagram of the atomization component in the atomization device, Figure 11 yes Figure 10 Axial cross-sectional view of the atomization assembly, Figure 12 yes Figure 11 Axial cross-sectional view after removing the liquid storage component, Figure 13 yes Figure 10 Schematic diagram of the disassembled structure of the atomizer assembly. In one embodiment, the atomizer assembly 130 includes a sealing sleeve assembly 131, a liquid storage component 135 and an atomizer core 136. The sealing sleeve assembly 131 is sealed against the inner wall of the housing 110 and is sealed against the vent tube 112. The sealing sleeve assembly 131 and the inner wall of the housing 110 jointly define the liquid storage chamber 111. A mounting chamber is provided in the sealing sleeve assembly 131, and the liquid storage component 135 is accommodated in the mounting chamber. A connecting hole 1310 is provided on the side of the sealing sleeve assembly 131 facing the liquid storage chamber 111, so that the mounting chamber is connected to the liquid storage chamber 111 through the connecting hole 1310, so that the liquid storage component 135 can absorb the atomized liquid stored in the liquid storage chamber 111. The atomizer core 136 is the main component of the atomizer assembly 130 that performs a heating function. The atomizer core 136 is connected to the vent tube 112. The liquid storage component 135 surrounds the atomizer core 136 so that the atomizer core 136 can heat and atomize the atomized liquid adsorbed in the liquid storage component 135. The heated and atomized gas can enter the vent tube 112 from the atomizer core 136.

[0072] In this embodiment, the sealing sleeve assembly 131 is mainly used to install the liquid storage member 135. The atomized liquid stored in the liquid storage chamber 111 can enter the installation chamber of the sealing sleeve assembly 131 through the connecting hole 1310 on the sealing sleeve assembly 131 and be absorbed by the liquid storage member 135 in the installation chamber. In addition, because the sealing sleeve assembly 131 is sealed against the inner wall of the housing 110 and is in sealed contact with the vent pipe 112, the atomized liquid in the liquid storage chamber 111 will not leak from the gap between the outer wall of the sealing sleeve assembly 131 and the inner wall of the housing 110, nor will it enter the vent pipe 112 through the gap between the sealing sleeve assembly 131 and the vent pipe 112. This ensures that the atomized liquid in the liquid storage chamber 111 will only enter the installation chamber of the sealing sleeve assembly 131 through the connecting hole 1310 on the sealing sleeve assembly 131 and be absorbed by the liquid storage member 135.

[0073] This embodiment shows an atomization method in which the atomized liquid in the liquid storage chamber 111 first enters the liquid storage part 135 in the atomization assembly 130, and is then heated and atomized by the atomization core 136. The heated and atomized gas then enters the ventilation tube 112 from the atomization core 136, extending the journey of the atomized liquid from the liquid storage chamber 111 to the atomization core 136, avoiding the rapid saturation of the atomization core 136 and causing leakage. It can be understood that in other embodiments, the atomization assembly 130 can also adopt other structures and is not limited to the structure and heating atomization method of this embodiment. In addition, the liquid guide efficiency of the liquid storage part 135 is lower than the liquid guide efficiency of the liquid guide part in the atomization core 136, for example, the porosity of the liquid storage part 135 is less than the porosity of the liquid guide part in the atomization core 136, so as to avoid the rapid saturation of the atomization core 136 and causing leakage.

[0074] Continue reading Figures 10 to 13 In one embodiment, the sealing sleeve assembly 131 includes a partition 132, a first seal 133 and a second seal 134. The first seal 133 and the second seal 134 respectively seal the two ends of the partition 132 in the axial direction of the atomizing device 100. The first seal 133 and the second seal 134 can be made of elastic materials such as silicone to better seal the two ends of the partition 132, and can better seal and fit the inner wall of the shell 110 to prevent the atomized liquid in the liquid storage chamber 111 from leaking through the gap between the first seal 133 / the second seal 134 and the inner wall of the shell 110. In order to ensure that the liquid storage function of the liquid storage part 135 is not affected by the deformation of the partition 132 in the installation cavity, the partition 132 can be made of hard material. The first seal 133 and the second seal 134 can both be sealed and fit the inner wall of the shell 110, or one of the first seal 133 and the second seal 134 can be sealed and fit the inner wall of the shell 110. Figure 2 The diagram shows a situation where only the first sealing member 133 is sealed against the inner wall of the housing 110. In these embodiments, only the first sealing member 133 is sealed against the inner wall of the housing 110, and a certain distance between the second sealing member 134 and the inner wall of the housing 110 is provided to facilitate the assembly between the liquid suction component 140 and the atomization component 130 described later. The assembly structure of the two will be described in detail later.

[0075] See again Figure 2 as well as Figures 10 to 13 The following describes in detail the assembly structure between the partition member 132, the first sealing member 133 and the second sealing member 134.

[0076] The partition member 132 includes a partition body 1321, a partition end plate 1322, and a partition sleeve 1323. The partition body 1321, partition end plate 1322, and partition sleeve 1323 can be integrally formed. The partition body 1321 is a cylindrical shell structure, with one axial end connected to the partition end plate 1322 and the other end open. The partition sleeve 1323 protrudes from the partition end plate 1322 and is located on the side of the partition end plate 1322 facing away from the second sealing member 134. One end of the vent pipe 112 is inserted into the partition sleeve 1323 and abuts the partition end plate 1322, thereby positioning the partition member 132 within the housing 110, thereby positioning the sealing sleeve assembly 131 within the housing 110. A vent hole is formed on the partition end plate 1322 inside the partition sleeve 1323 , so that the gas heated and atomized by the atomizer core 136 can enter the ventilation pipe 112 through the vent hole on the partition end plate 1322 .

[0077] The first sealing member 133 is sealedly connected to the end of the partition member 132 facing the liquid storage chamber 111. The first sealing member 133 comprises a first sealing plate 1331, a first sealing end plate 1332, and a first sealing boss 1333. The first sealing plate 1331, the first sealing end plate 1332, and the first sealing boss 1333 can be integrally formed. The first sealing plate 1331 is a flat cylindrical shell structure. The first sealing plate 1331 is attached to the outer surface of the partition body 1321 of the partition member 132 and only covers a portion of the outer wall of the partition body 1321. The outer surface of the first sealing plate 1331 is sealed against the inner wall of the housing 110. The first sealing end plate 1332 is fixed to the end of the first sealing plate 1331 facing the liquid storage chamber 111 and is sealed against the partition end plate 1322. The first sealing boss 1333 is protruding from the side of the first sealing end plate 1332 facing away from the second sealing member 134. The interior of the first sealing boss 1333 is a hollow structure. The partition sleeve 1323 of the partition member 132 is located within the hollow structure of the first sealing boss 1333, so that the first sealing boss 1333 covers the surface of the partition sleeve 1323. The first sealing end plate 1332 defines a first through hole 13320 on the outside of the first sealing boss 1333. The partition end plate 1322 defines a second through hole 13220 on the outside of the partition sleeve 1323. The first through hole 13320 and the second through hole 13220 are aligned to form the communicating hole 1310 of the sealing sleeve assembly 131, through which the atomized liquid in the liquid storage chamber 111 flows into the sealing sleeve assembly 131.

[0078] The second sealing member 134 is sealingly connected to the end of the partition member 132 facing away from the liquid storage chamber 111. Specifically, the second sealing member 134 is sealingly connected to the open end of the partition member 132. After the liquid storage member 135 is installed in the installation cavity of the partition member 132, the second sealing member 134 can seal the open end of the partition member 132. The second sealing member 134 includes a second sealing panel 1341 and a second sealing end plate 1342. The second sealing panel 1341 and the second sealing end plate 1342 can be integrally formed. The second sealing panel 1341 is in the form of a flat cylindrical shell 110. It is attached to the outer surface of the partition body 1321 of the partition member 132 and only covers a portion of the outer wall of the partition body 1321.

[0079] A first convex ring 13211 and a second convex ring 13212 can also be provided on the outer wall of the partition body 1321, and the end of the first sealing plate 1331 of the first seal 133 abuts against the first convex ring 13211 to better achieve the positioning of the first seal 133 on the partition member 132, and the end of the second sealing plate 1341 of the second seal 134 abuts against the second convex ring 13212 to better achieve the positioning of the second seal 134 on the partition member 132.

[0080] When the atomizer assembly 130 is actually installed, the liquid storage component 135, the atomizer core 136, the partition component 132, the first seal 133 and the second seal 134 can be assembled into the atomizer assembly 130 first, and then the atomizer assembly 130 can be installed as a whole into the housing 110 to facilitate and quickly install the atomizer assembly 130.

[0081] See again Figure 2 In one embodiment, the atomizing device 100 further includes a liquid suction component 140, which is combined with Figure 14 and Figure 15 , Figure 14 yes Figure 2 A three-dimensional schematic diagram of the liquid suction component in the atomization device, Figure 15 yes Figure 14 The disassembled structure diagram of the liquid absorption component. The liquid absorption component 140 is located on the side of the atomizer component 130 away from the liquid storage chamber 111 in the axial direction of the atomizer device 100. The liquid absorption component 140 includes a bracket 141 and a liquid absorption member 142. The bracket 141 is fixed to the housing 110. The bracket 141 is mainly used to install the liquid absorption member 142. The bracket 141 is provided with a receiving chamber 14110 facing the atomizer component 130. The liquid absorption member 142 is located in the receiving chamber 14110. The liquid absorption member 142 can absorb the atomized liquid leaked from the atomizer core 136 of the atomizer component 130, the air in the vent tube 112 of the atomizer, and the condensed liquid formed after the aerosol condenses.

[0082] In one embodiment, there are at least two liquid-absorbing parts 142, and the liquid-absorbing parts 142 are arranged at intervals. After a single liquid-absorbing part 142 absorbs condensate and expands, it can contact other liquid-absorbing parts 142. One of the liquid-absorbing parts 142 fills part of the space of the accommodating cavity 14110 along the height direction of the atomizing device 100. The unfilled space of the accommodating cavity 14110 along the height direction of the atomizing device 100 forms a channel for airflow. In order to increase the condensate receiving capacity as much as possible, the other liquid-absorbing parts 142 should occupy the height of the accommodating cavity 14110 as much as possible to avoid wasting the space in the accommodating cavity 14110.

[0083] Figure 2 as well as Figure 14-15 The figure shows a case where there are two liquid absorbent members 142, namely 142a and 142b. The liquid absorbent member 142a is the main liquid absorbent member for absorbing condensate. The liquid absorbent members 142a and 142b are spaced apart. For example, a partition or other structure may be provided between the two. However, the liquid absorbent members 142a and 142b are not completely isolated. When the liquid absorbent member 142a absorbs condensate, it expands. After expanding to a certain extent, the liquid absorbent member 142a contacts the liquid absorbent member 142b, so that the liquid absorbent member 142b can also absorb condensate.

[0084] The liquid absorption member 142a fills part of the space of the accommodating chamber 14110 along the height direction of the atomizing device 100. The space of the accommodating chamber 14110 not filled by the liquid absorption member 142a along the height direction of the atomizing device 100 forms a channel for air flow. In order to increase the capacity of collecting condensate as much as possible, the liquid absorption member 142b basically occupies the entire height of the accommodating chamber 14110.

[0085] In this embodiment, the wick 136 is provided in multiple pieces because the wiring of the atomizer core 136 needs to pass through the wick 142 to connect to other components of the atomizer device, such as the control circuit board. Therefore, a hole needs to be opened in the wick 142. In addition, the heights of the two wicks 142a and 142b are different. Providing multiple pieces of the wick 142 makes it easier to cut and process the shapes of the two wicks 142a and 142b. It is understood that in other embodiments, the wick 142 can also be a single piece.

[0086] Furthermore, the atomizing device 100 of the present application can be a product that can be filled with oil or not. For a product that cannot be filled with oil, since the number of uses is limited, less condensate is formed inside the atomizing device 100, so the size of the liquid absorbing member 142 for absorbing the condensate can be set to be relatively small. For a product that can be filled with oil, since the atomized liquid can be repeatedly injected into the liquid storage chamber 111, more condensate will be formed after long-term use, and a larger storage space is required for the condensate. The size of the liquid absorbing member 142 can be set to be larger to accommodate more condensate, for example, it can be like Figure 2As shown, the height of the liquid-absorbing member 142 is set to be close to the thickness of the liquid-storage member 135, or even greater than the thickness of the liquid-storage member 135. The present application does not limit the specific height of the liquid-absorbing member 142, which can be determined according to the design of the actual product.

[0087] The bracket 141 can be fixed to the housing 110 by means of snap-fitting or other methods. Specifically, the bracket 141 includes a bracket body 1411, which is a cylindrical housing. The bracket body 1411 is located within the housing 110, and a receiving cavity 14110 is formed within the bracket body 1411. The bracket body 1411 is open at one end of the receiving cavity 14110, so that the absorbent member 142 can be installed into the receiving cavity 14110 through the opening. The outer wall of the bracket body 1411 is provided with a first snap-fitting protrusion 14111. The housing 110 is provided with a first snap-fitting hole 117. The first snap-fitting protrusion 14111 snaps into the first snap-fitting hole 117, thereby achieving a fixed connection between the bracket body 1411 and the housing 110. It will be understood that in other embodiments, the bracket 141 can also be fixed to the housing 110 by other means besides snap-fitting.

[0088] In addition, one end of the bracket body 1411 facing the liquid storage chamber 111 also abuts against the second convex ring 13212 on the partition piece 132 and surrounds the second sealing piece 134, so that the two ends of the atomizer assembly 130 in the axial direction of the atomizer device 100 respectively abut against the ventilation pipe 112 and the bracket 141, that is, the atomizer assembly 130 is clamped between the ventilation pipe 112 and the bracket 141 to achieve the fixed installation of the atomizer assembly 130 in the shell 110, and the end of the bracket body 1411 facing the liquid storage chamber 111 is also provided with a hanging ring, and a second snap-fitting hole 14112 is provided in the hanging ring, and the outer wall of the partition piece 132 is provided with a second snap-fitting protrusion 13213, and the second snap-fitting protrusion 13213 is snap-fitted into the second snap-fitting hole 14112 to strengthen the fixed connection between the atomizer assembly 130 and the liquid suction assembly 140.

[0089] In order to facilitate the entry of gas outside the atomization device 100 into the atomization device 100 so as to form an aerosol after the atomization core 136 heats the atomized liquid, the bracket 141 also includes an air inlet portion 1412, a portion of the air inlet portion 1412 is located inside the bracket body 1411, and the other portion is located outside the bracket body 1411. An air inlet cavity is provided in the air inlet portion 1412, an air inlet end 14121 of the air inlet cavity is located outside the bracket body 1411, and an air outlet end 14122 of the air inlet cavity is located inside the bracket body 1411. Specifically, the air outlet end 14122 of the air inlet cavity is located in the space of the accommodating cavity 14110 that is not filled by the liquid absorption component 142a at its height. External air can enter the air inlet cavity through the air inlet end 14121 of the air inlet cavity, and enter the accommodating cavity 14110 of the bracket 141 from the air outlet end 14122 of the air inlet cavity, and enter the atomization core 136 through the accommodating cavity 14110.

[0090] See again Figure 2 and Figure 3 In one embodiment, the atomizer device 100 further includes a power supply module 150. The power supply module 150 is located on a side of the atomizer assembly 130 that is axially away from the liquid storage chamber 111 of the atomizer device 100. The power supply module 150 is connected to the atomizer core 136 for supplying power to the atomizer core 136. It is understood that in other embodiments, the atomizer device 100 may not be provided with the power supply module 150, but may directly power the atomizer core 136 of the atomizer device 100 through an external device, such as a charging device.

[0091] Specifically, the power supply module 150 includes a power supply 151 and a control circuit board 152. The control circuit board 152 is electrically connected to the power supply 151 and the atomizer core 136. The power supply 151 is used to provide electricity. When the atomizer device 100 includes a liquid suction component 140, the liquid suction component 140 can be arranged between the atomizer component 130 and the power supply module 150 along the axial direction of the atomizer device 100 to prevent the atomized liquid leaked from the atomizer component 130 from contacting the power supply module 150 and affecting the normal operation of the power supply module 150. The pins of the atomizer core 136 can be connected to the control circuit board 152 through a wire passing through the liquid suction component 140 to achieve electrical connection between the atomizer core 136 and the control circuit board 152. The control circuit board 152 can be abutted against the end of the bracket body 1411 away from the atomizer assembly 130 and clamped on the shell 110. For example, the edge of the control circuit board 152 can be clamped into the third clamping hole 118 provided on the end of the shell 110 facing the power supply module 150 to achieve the control circuit board 152 being clamped to the shell 110, thereby achieving the fixed installation of the control circuit board 152 in the shell 110. The power supply 151 is located on the side of the control circuit board 152 away from the atomizer assembly 130 in the axial direction of the atomizer device 100, and is located on the side of the air inlet part 1412 in the radial direction of the atomizer device 100, so that the structural arrangement in the atomizer device 100 is more compact.

[0092] See again Figure 2 and Figure 3 In this embodiment, the atomizing device 100 may further include a bottom cover 160, see Figure 16 , Figure 16 yes Figure 3 The bottom cover 160 can be fixed to the housing 110 to cover the power supply module 150 to prevent the power supply module 150 from being exposed.

[0093] See again Figure 3 and Figure 4 In one embodiment, to facilitate the injection of atomized liquid into the liquid storage chamber 111, the housing 110 is further provided with an injection hole 119. The injection hole 119 is located on a side of the housing 110 away from the atomizer assembly 130 and can be sealed with a liquid injection silicone 190. After the atomizer assembly 130 is installed in the housing 110, atomized liquid can be injected into the liquid storage chamber 111 through the injection hole 119, and then the injection silicone 190 can be used to seal the injection hole 119 to prevent the atomized liquid from leaking.

[0094] See again Figure 2 In one embodiment, the atomizing device 100 further includes a housing 170, which is sleeved over the housing 110 and has openings at both ends. The housing 170 covers a portion of the outer surface of the housing 110 and exposes the mouthpiece 114 of the housing 110 for the user to inhale. The housing 170 extends to connect to the bottom cover 160 and covers the air inlet 1412 of the bracket 141 and the control circuit board 152. The housing 170 can also cover the liquid-injected silicone 190 on the housing 110. In this embodiment, the atomizing device 100 has a simpler appearance by providing the housing 170.

[0095] In this embodiment, the housing 170 can be snap-fitted to the housing 110 to achieve relative fixation between the housing 170 and the housing 110. Specifically, the outer wall of the housing 110 is provided with a third snap-fitting protrusion 115 and a fourth snap-fitting protrusion 116, and the inner wall of the housing 170 is provided with a fifth snap-fitting protrusion 171 and a sixth snap-fitting protrusion 172. The fifth snap-fitting protrusion 171 abuts against the third snap-fitting protrusion 115, and the fourth snap-fitting protrusion 116 abuts against the sixth snap-fitting protrusion 172, thereby achieving a fixed connection between the housing 170 and the housing 110. It will be understood that in other embodiments, other methods besides snap-fitting can be used to achieve relative fixation between the housing 170 and the housing 110.

[0096] The bottom cover 160 can be snapped onto the outer shell 170, thereby realizing a fixed connection between the bottom cover 160 and the shell 110. Specifically, the outer shell 170 covers a portion of the outer surface of the bottom cover 160, and the bottom cover 160 is provided with a seventh snapping protrusion 161 at a position covered by the outer shell 170. The inner wall of the outer shell 170 is provided with an eighth snapping protrusion corresponding to the seventh snapping protrusion 161. The seventh snapping protrusion 161 can abut against the end of the eighth snapping protrusion facing the liquid storage chamber 111, and the end of the bottom cover 160 facing the control circuit board 152 abuts against the control circuit board 152. Therefore, when the outer shell 170 is fixed on the shell 110, the bottom cover 160 can achieve a fixed connection between the bottom cover 160 and the outer shell 170 through the abutment between the seventh snapping protrusion 161 and the eighth snapping protrusion, that is, achieve a fixed connection between the bottom cover 160 and the shell 110.

[0097] In one embodiment, the atomizing device 100 further includes a magnetic component 180, which can be used for magnetic fixation between the atomizing device 100 and an external device. For example, the external device can be a charging device 200 capable of charging the power supply module 150 of the atomizing device 100. The magnetic component 180 can be provided on the housing 170 of the atomizing device 100 to facilitate magnetic connection between the external device and the atomizing device 100. Correspondingly, the external device can also be provided with a magnetic component or made of a metal material that can be magnetically attracted by the magnetic component 180, so as to achieve a magnetic connection between the atomizing device 100 and the external device, so that the atomizing device 100 and the external device are connected as a whole.

[0098] The power supply module 150 also includes an electrode for electrically connecting to the charging device 200, and the electrode is electrically connected to the control circuit board 152. When the charging device 200 and the atomization device 100 are fixed by the magnetic attraction component 180, the electrodes of the charging device 200 and the atomization device 100 are in contact and conductive, so that the charging device 200 charges the power supply module 150 of the atomization device 100, specifically, charges the power supply 151 of the power supply module 150.

[0099] This application also provides a nebulizer device, please refer to Figure 17 , Figure 17It is a schematic diagram of the three-dimensional structure of an embodiment of the atomizing device provided in the present application. The atomizing device 10 includes an atomizing device 100 and a charging device 200. The specific structure of the atomizing device 100 refers to the above embodiment. The charging device 200 is electrically connected to the atomizing device 100, and the charging device 200 is used to charge the atomizing device 100. Specifically, when the atomizing device 100 is provided with a power supply module 150, the charging device 200 is used to charge the power supply module 150 of the atomizing device 100, and more specifically, to charge the power supply 151 of the power supply module 150. Of course, the charging device 200 may not be provided with a power supply module 150, and the atomizing core 136 of the atomizing device 100 may be powered directly through the charging device 200 to heat the atomized liquid.

[0100] The charging device 200 is detachably connected to the atomizer 100. Specifically, the charging device 200 is provided with a magnetic component or is made of a metal material that can be magnetically attracted by the magnetic component 180 on the atomizer 100, thereby achieving a magnetic connection between the charging device 200 and the atomizer 100, so that the charging device 200 and the atomizer 100 are connected as a whole. When the charging device 200 and the atomizer 100 are fixed by the magnetic component 180, the electrodes of the charging device 200 and the atomizer 100 are in contact and conductive, so that the charging device 200 can charge the power supply module 150 of the atomizer 100.

[0101] The charging device 200 includes at least a rechargeable battery. The charging device 200 can use an external power source to charge the rechargeable battery, which in turn charges the power supply device. For example, the charging device 200 can be provided with a USB port for connecting to an external power source. It is understood that in other embodiments, the rechargeable battery can also provide power for other functional modules of the atomization device 100.
