TECHNICAL FIELD
[0001] This application relates to the field of atomization technology, and specifically to an atomization device and an atomization assembly thereof.BACKGROUND
[0002] An atomization device refers to a device that converts stored atomizable medium into aerosol through methods such as heating or ultrasonication. Current atomization devices are usually equipped with an atomization module and a storage cavity for holding the atomization substrate. The atomization substrate in the storage cavity can enter the atomization module, and is heated and atomized to form aerosol. The aerosol mixes with air entering the atomization module and then flows out of an atomization cavity for a user to inhale.
[0003] Currently, in most atomization devices on the market, an e-liquid guide hole of the atomization module is in communication with the storage cavity, resulting in the atomization module being immersed in the atomization substrate for a long time. This causes an e-liquid guide body in the atomization module to remain in a saturated state for a long time, which easily leads to leakage of the atomization substrate through an atomization channel of the atomization module, resulting in contamination. Moreover, this leakage affects the taste of the aerosol generated by atomization. In addition, the leaked atomization substrate may even be inhaled into the user's mouth during use, bringing extremely poor experience to consumers. Therefore, there is an urgent need in the industry for a new atomization assembly structure to address the problem of storage and e-liquid leakage.SUMMARY
[0004] The main technical problem solved by this application is to provide an atomization device and its atomization assembly to address the issue of oil leakage during storage.
[0005] A first aspect of embodiments of this application provides an atomization assembly. The atomization assembly includes a housing, an atomization module, and a sliding member. The atomization module is disposed inside the housing, and an e-liquid guide hole is formed in a side wall of the atomization module. A storage cavity and a buffer cavity are arranged in the housing; and the storage cavity is used for storing an atomization substrate, and the buffer cavity is in communication with the e-liquid guide hole. The sliding member is slidably arranged in the housing and is movable between an open position and a closed position, so as to selectively connect or separate the storage cavity and or from the buffer cavity.
[0006] According to an embodiment of this application, the housing is provided with a partition plate having a through-hole. The partition plate divides space inside the housing into the storage cavity and the buffer cavity, which are communicated through the through-hole. The sliding member is inserted through the through-hole, and an e-liquid blocking part is provided at one end of the sliding member close to the storage cavity. When the sliding member is in the closed position, the e-liquid blocking part seals the through-hole, to separate the storage cavity from the buffer cavity.
[0007] According to an embodiment of this application, the sliding member includes a linkage member. The linkage member includes a main body part, and a first end part and a second end part located at both ends of the main body part. The first end part is connected to the e-liquid blocking part. The atomization assembly further includes a base, and the buffer cavity is located between the base and the housing. The second end part is at least partially inserted into the base and is slidable relative to the base, so that under driving by an external force, the linkage member is driven to slide along the base, so as to drive the e-liquid blocking part away from the through-hole.
[0008] According to an embodiment of this application, the atomization assembly further includes an elastic member disposed in the buffer cavity. Both ends of the elastic member are respectively connected to the sliding member and the housing. The elastic member is used to provide an elastic restoring force that drives the sliding member to move from the open position to the closed position.
[0009] According to an embodiment of this application, the base is provided with a through docking channel. The second end part of the linkage member is slidably disposed in the docking channel, and the second end part is able to be pushed to move toward the buffer cavity.
[0010] According to an embodiment of this application, the e-liquid blocking part and the first end part are detachably connected.
[0011] According to an embodiment of this application, a protruding part is provided between the main body part and the second end part of the linkage member. The elastic member is compressed between the protruding part and the housing to apply a force to the protruding part that is away from the housing, so that the e-liquid blocking part seals the through-hole.
[0012] According to an embodiment of this application, the sliding member is provided with a hollow channel, as well as an e-liquid inlet hole and an e-liquid outlet hole that are in communication with the hollow channel. When the sliding member is in the open position, the e-liquid inlet hole is located in the storage cavity and the e-liquid outlet hole is located in the buffer cavity, so that the atomization substrate in the storage cavity is able to reach the atomization module through the hollow channel.
[0013] A second aspect of embodiments of this application further provides an atomization device, which includes the atomization assembly described in any one of the above embodiments. The atomization device further includes a battery assembly, and the battery assembly is electrically connected to the atomization assembly to supply power to the atomization assembly.
[0014] According to an embodiment of this application, the battery assembly is convexly provided with an abutting part. When the atomization assembly is connected to the battery assembly, the abutting part abuts against the sliding member, so that the sliding member is in the open position.
[0015] The atomization device and its atomization assembly provided by this application are configured by arranging a sliding member in the housing to control the connection or blocking between the storage cavity and the buffer cavity, thereby opening or closing the channel for the atomization substrate in the storage cavity to enter the atomization module, and further addressing the issue of oil leakage of the product during storage.BRIEF DESCRIPTION OF THE DRAWINGS

[0020] An embodiment of this application provides an atomization assembly 10. Please refer to FIG. 1 to FIG. 3 together. FIG. 1 is an axial cross-sectional view of an embodiment of the atomization assembly of this application, FIG. 2 is a cross-sectional schematic diagram of the atomization assembly shown in FIG. 1 when a sliding member is in a closed position, and FIG. 3 is a cross-sectional schematic diagram of the atomization assembly shown in FIG. 1 when the sliding member is in an open position. The atomization assembly 10 includes a housing 110, an atomization module 120, and a sliding member 130. Specifically, the atomization module 120 is disposed in the housing 110, and an e-liquid guide hole 1201 is formed in a side wall thereof. A storage cavity 1101 and a buffer cavity 1102 are arranged in the housing 110; and the storage cavity 1101 is used for storing an atomization substrate, and the buffer cavity 1102 is in communication with the e-liquid guide hole 1201. The sliding member 130 is slidably arranged in the housing 110 and is movable between the open position and the closed position to connect or separate the storage cavity 1101 and or from the buffer cavity 1102. When the sliding member 130 is in the open position, the atomization substrate in the storage cavity 1101 can enter the atomization module 120 through the buffer cavity 1102 and the e-liquid guide hole 1201, and the atomization module 120 can heat and atomize the atomization substrate to form aerosol. Specifically, the atomization module 120 may include an atomization tube 121 and an e-liquid guide member 122 inside the atomization tube 121. The e-liquid guide hole 1201 is provided on the side wall of the atomization tube 121, and the e-liquid guide member 122 wraps around a heating element (not shown in the figure). The e-liquid guide member 122 can guide the atomization substrate in the buffer cavity 1102 to a position close to the heating element through the e-liquid guide hole 1201, so that the atomization substrate is heated and atomized to form aerosol. The e-liquid guide member 122 may be made of ceramic or e-liquid guide cotton, and the heating element may be a heating wire or a heating sheet, etc.
[0021] Optionally, please refer to FIG. 4, which is a cross-sectional schematic diagram of the housing of the atomization assembly shown in FIG. 1. The housing 110 is provided with a partition plate 111 having a through-hole 1103. The partition plate 111 divides space inside the housing 110 into the storage cavity 1101 and the buffer cavity 1102, and the storage cavity 1101 and the buffer cavity 1102 can be communicated through the through-hole 1103. The sliding member 130 is inserted through the through-hole 1103, and one end of the sliding member 130 is provided with an e-liquid blocking part 131. The projection area of the e-liquid blocking part 131 along the normal direction of the through-hole 1103 is larger than the cross-sectional area of the through-hole 1103, so that it can completely cover the through-hole 1103. When the sliding member 130 is in the closed position, the e-liquid blocking part 131 can seal the through-hole 1103 to separate the storage cavity 1101 from the buffer cavity 1102. Further, the e-liquid blocking part 131 may be made of plastic, metal, metal alloy, etc., and its shape may be circular, square, or other shapes matching the through-hole 1103.
[0022] Optionally, please refer to FIG. 5, which is a schematic structural diagram of a linkage member of the atomization assembly shown in FIG. 1. The sliding member 130 further includes a linkage member 132. The linkage member 132 includes a main body part 1323, and a first end part 1321 and a second end part 1322 located at both ends of the main body part 1323, and the first end part 1321 is connected to the e-liquid blocking part 131. Optionally, the e-liquid blocking part 131 and the linkage member 132 may be of an integrated structure, which can be formed by integral injection molding. Further, the e-liquid blocking part 131 and the linkage member 132 may alternatively be of a split structure, and the e-liquid blocking part 131 and the first end part 1321 of the linkage member 132 are detachably connected. Specifically, the first end part 1321 and the e-liquid blocking part 131 can be connected together by means of clamping or interference fit. The linkage member 132 may be made of materials such as plastic, metal, or metal alloy, and the shape of the main body part 1323 may be cylindrical, prismatic, or other shapes adapted to the through-hole 1103. When the atomization assembly 10 is connected to a battery assembly 20, the sliding member 130 is in the open position, and the second end part 1322 is held against by the battery assembly 20, so that the linkage member 132 drives the e-liquid blocking part 131 away from the through-hole 1103. Specifically, when the sliding member 130 is in the open position, the e-liquid blocking part 131 and the first end part 1321 of the linkage member 132 are far away from the through-hole 1103 and enter the storage cavity 1101. The e-liquid blocking part 131 no longer seals the through-hole 1103, and the atomization substrate in the storage cavity 1101 can enter the buffer cavity 1102 through the through-hole 1103, and then enter the atomization module 120 through the e-liquid guide hole 1201.
[0023] Optionally, the atomization assembly 10 further includes an elastic member 140. The elastic member 140 is connected to the sliding member 130, and the elastic member 140 is used to provide an elastic force that drives the sliding member 130 to move from the open position to the closed position. Further, the elastic member 140 is made of plastic or metal alloy with an elastic deformation capability. Specifically, the elastic member 140 may be a spring and is arranged around the linkage member 132.
[0024] Optionally, please refer to FIG. 6, which is a cross-sectional schematic diagram of a base of the atomization assembly shown in FIG. 1. The atomization assembly 10 further includes a base 150, and the buffer cavity 1102 is located between the base 150 and the housing 110. The base 150 is provided with a through docking channel 1501 and an air inlet channel 1502. The air inlet channel 1502 is in communication with the atomization tube 121 of the atomization module 120, and gas outside the atomization assembly 10 can enter the atomization tube 121 through the air inlet channel 1502. The second end part 1322 of the linkage member 132 is located in the docking channel 1501, and the second end part 1322 is adapted to the docking channel 1501, so that there is a small fitting gap between the second end part 1322 and the docking channel 1501, and they are slidable relative to each other, so that the linkage member 132 is driven to slide along the docking channel 1501 under driving by an external force. When the atomization assembly 10 is connected to the battery assembly 20, the battery assembly 20 can hold against the second end part 1322, so that the sliding member 130 as a whole slides away from the base 150 to the open position, thereby making the e-liquid blocking part 131 leave the through-hole 1103 and enabling the storage cavity 1101 and the buffer cavity 1102 to be communicated.
[0025] Further, the first end part 1321 of the linkage member 132 is clamped in the e-liquid blocking part 131. A protruding part 1324 is provided between the main body part 1323 and the second end part 1322 of the linkage member 132. One end of the elastic member 140 is connected to the protruding part 1324, and the other end is connected to the housing 110 around the through-hole 1103. The elastic member 140 is compressed between the protruding part 1324 and the housing 110 to apply a force to the protruding part 1324 that is away from the housing 110, so that the e-liquid blocking part 131 seals the through-hole 1103.
[0026] Optionally, the cross-sectional area of the main body part 1323 of the linkage member 132 is smaller than the area of the through-hole 1103, so that when the sliding member 130 is in the open position, there is a gap between the sliding member 130 and the through-hole 1103, and the atomization substrate in the storage cavity 1101 can enter the buffer cavity 1102 from the gap.
[0027] Further, please refer to FIG. 7 to FIG. 10 together. FIG. 7 is an axial cross-sectional view of another embodiment of the atomization assembly of this application, FIG. 8 is a cross-sectional schematic diagram of the atomization assembly shown in FIG. 7 when the sliding member is in the closed position, FIG. 9 is a cross-sectional schematic diagram of the atomization assembly shown in FIG. 7 when the sliding member is in the open position, and FIG. 10 is a schematic structural diagram of the linkage member of the atomization assembly shown in FIG. 7. One end of the elastic member 140 in this embodiment is connected to the protruding part 1324, and the other end is connected to the partition plate 111 around the through-hole 1103. When the sliding member 130 is in the closed position, the elastic member 140 is in a compressed state, and the protruding part 1324 is far away from the through-hole 1103 under an elastic force of the elastic member 140, so that the e-liquid blocking part 131 seals the through-hole 1103. In this case, the protruding part 1324 can abut against the base 150 and serve as a limit for downward movement of the linkage member 132 to an extreme position.
[0028] Optionally, the main body part 1323 is provided with a hollow channel 13231, as well as an e-liquid inlet hole 13232 and an e-liquid outlet hole 13233 that are in communication with the hollow channel 13231. When the atomization assembly 10 is connected to the battery assembly 20, the second end part 1322 of the linkage member 132 is held against by the battery assembly 20, so that the sliding member 130 moves from the closed position to the open position. The e-liquid inlet hole 13232 moves from the buffer cavity 1102 to the storage cavity 1101, and the e-liquid outlet hole 13233 is located in the buffer cavity 1102. The atomization substrate in the storage cavity 1101 can enter the hollow channel 13231 through the e-liquid inlet hole 13232 and then enter the buffer cavity 1102 from the e-liquid outlet hole 13233. Further, when the sliding member 130 is in the open position, the e-liquid outlet hole 13233 can be directly opposite to the e-liquid guide hole 1201, so that the atomization substrate in the hollow channel 13231 can directly enter the atomization module 120 through the e-liquid outlet hole 13233 and the e-liquid guide hole 1201.
[0029] Optionally, the atomization assembly 10 further includes a mouthpiece 160. The aerosol generated by the atomization module 120 heating and atomizing the atomization substrate can be discharged from the mouthpiece 160 through the atomization tube 121. Sealing rings 170 are arranged between the mouthpiece 160 and the housing 110, between the mouthpiece 160 and the atomization module 120, between the base 150 and the housing 110, and between the second end part 1322 and the docking channel 1501, to prevent the atomization substrate in the storage cavity 1101 and the buffer cavity 1102 from leaking. Further, a metal electrode 180 is further installed on the base 150. The metal electrode 180 is riveted with a heating wire of the atomization module 120 and can be electrically connected to the battery assembly 20 to supply power to the atomization module 120.
[0030] Further, please refer to FIG. 11 to FIG. 13 together. FIG. 11 is a cross-sectional schematic diagram of an embodiment of an atomization device of this application, FIG. 12 is a cross-sectional schematic diagram of the atomization device shown in FIG. 11 from another angle, and FIG. 13 is a cross-sectional schematic diagram of a fixing bracket of the atomization device shown in FIG. 11. An embodiment of this application further provides an atomization device, which includes the atomization assembly 10 in the above embodiment and a battery assembly 20. The battery assembly 20 is electrically connected to the atomization assembly 10 to supply power to the atomization assembly 10.
[0031] Optionally, the battery assembly 20 includes a fixing bracket 210. The fixing bracket 210 is provided with an abutting part 211. When the atomization assembly 10 is connected to the battery assembly 20, the abutting part 211 abuts against the sliding member 130, so that the sliding member 130 is in the open position. Specifically, the abutting part 211 can extend into the docking channel 1501 of the base 150 and abut against the second end part 1322 of the linkage member 132, so that the linkage member 132 drives the e-liquid blocking part 131 to leave the through-hole 1103. Optionally, in some other embodiments, the fitting relationship between the abutting part 211 and the docking channel 1501 can also play a role in preventing the atomization assembly 10 from being universally matched with the battery assembly 20.
[0032] Optionally, the battery assembly 20 further includes a spring electrode 220. The spring electrode 220 can be electrically connected to the metal electrode 180 of the atomization assembly 10 to conduct the current of a battery 250 and supply power to the atomization module 120. Further, the battery assembly 20 is further provided with a magnet 230. The magnet 230 can attract the metal electrode 180 to ensure that the spring electrode 220 and the metal electrode 180 are not disconnected during a connection process of the atomization assembly 10 and the battery assembly 20. Further, the battery assembly 20 further includes a microphone 240. When a user inhales through the mouthpiece 160, the microphone 240 can sense changes in air flow and provide a signal to the battery 250, so that the battery outputs current to supply power to the atomization assembly 10, and the atomization module 120 further heats and atomizes the atomization substrate to form aerosol.
[0033] When the atomization assembly 10 is connected to the battery assembly 20, the sliding member 130 is in the open position, the storage cavity 1101 and the buffer cavity 1102 are communicated, and the atomization substrate can quickly enter the atomization module 120 to be heated and atomized. When the atomization device is not in use, the atomization assembly 10 and the battery assembly 20 can be separated, and the sliding member 130 automatically resets to the closed state under an elastic force of the elastic member 140, and the storage cavity 1101 is separated from the buffer cavity 1102, which prevents the atomization substrate from entering the atomization module 120 and causing e-liquid leakage.
[0034] In the atomization device and the atomization assembly thereof provided by this application, the sliding member 130 is arranged in the housing 110 to control the connection or separation between the storage cavity 1101 and the buffer cavity 1102, thereby opening or closing the channel for the atomization substrate in the storage cavity 1101 to enter the atomization module 120. This avoids the atomization module 120 being immersed in the atomization substrate for a long time when the atomization device is not in use, and alleviates the problem of e-liquid leakage during product storage.
[0035] The above are only partial embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the content of the description and drawings of the present application, or directly or indirectly applied in other related technical fields, shall similarly be included in the patent protection scope of the present application.
