Description

Technical Field

[0001] This application relates to the field of aerosol device technology, and more specifically, to an aerosol bomb and an aerosol device. Background Technology

[0002] An aerosol device is a device used to form an aerosol from an aerosol matrix, which is generally a fluid liquid substance.

[0003] An aerosol device generally includes a main body and an aerosol cartridge mounted on the main body. The aerosol cartridge contains an atomizing core and a cotton core. The aerosol cartridge also has a cavity inside, which is used to hold the aerosol matrix. The cotton core is in contact with the atomizing core to conduct the aerosol matrix to the atomizing core. The main body of the aerosol device is used to supply power to the atomizing core so that the atomizing core can form an aerosol from the aerosol matrix.

[0004] To improve the efficiency of aerosol devices, aerosol cartridges are often designed to be replaceable; a new cartridge can be replaced after the aerosol matrix inside is depleted. Therefore, aerosol cartridges are generally packaged or sold individually before use. However, before use, due to the fluidity of the aerosol matrix, the aerosol matrix flowing to the atomizing core can easily flow along the surface of the atomizing core and detach from it, resulting in aerosol matrix loss. Utility Model Content

[0005] In view of this, this application provides an aerosol bomb and an aerosol device that can reduce the risk of aerosol matrix being depleted before the aerosol bomb is used.

[0006] This application provides an aerosol bomb, including a liquid storage shell, a sealing assembly, and an atomizing core assembly. The liquid storage shell has a liquid storage cavity and a mounting hole, the mounting hole communicating with the liquid storage cavity, and the liquid storage cavity is configured to hold an aerosol matrix. The sealing assembly is connected to the liquid storage shell and seals the mounting hole. The atomizing core assembly is configured to cause the aerosol matrix to form an aerosol. The sealing assembly includes a sealing member and a rotating member. The sealing member is inserted into the mounting hole and connected to the liquid storage shell, and has a connecting portion for the flow of the aerosol matrix, the connecting portion communicating with the liquid storage cavity. At least a portion of the rotating member is located outside the liquid storage shell and rotatably connected to the sealing member. The rotating member has a receiving cavity, a liquid inlet, and a sealing portion, the liquid inlet communicating with the receiving cavity, and the sealing portion configured to seal the connecting portion. The atomizing core assembly is located within the receiving cavity and connected to the rotating member. When the rotating member is configured to rotate, the connecting portion may communicate with the liquid inlet or be sealed by the sealing portion.

[0007] In use, this aerosol bomb can be rotated to connect the connecting part with the liquid inlet, allowing the aerosol matrix in the storage chamber to flow sequentially along the connecting part and the liquid inlet into the receiving chamber, where it contacts the atomizing core assembly. This allows the atomizing core assembly to atomize the aerosol matrix. Before use, the rotating part can be rotated to seal the connecting part, thus sealing the storage chamber. This reduces the risk of loss or leakage of the aerosol matrix from the connecting part and also reduces the possibility of contamination of the aerosol matrix.

[0008] In some embodiments of this application, the rotating component is provided with a rotating sleeve, the sealing component is provided with a rotating hole, the rotating sleeve is inserted into the rotating hole and rotates with the rotating hole, the rotating component is provided with a limiting part, and the sealing component is provided with a mating part. The limiting part and the mating part cooperate to constrain the position of the rotating component relative to the sealing component in the axial direction of the rotating hole.

[0009] When assembling this aerosol bomb, the rotating sleeve is inserted into the rotating hole, and the limiting part is engaged with the mating part. The engagement of the limiting part and the mating part can constrain the position of the rotating part relative to the sealing part in the axial direction of the rotating hole, thereby reducing the risk of the rotating sleeve dislodging from the rotating hole and causing the rotating part to fall off, thus improving the stability of the rotating connection between the rotating part and the sealing part.

[0010] In some embodiments of this application, the sealing member is provided with an extension sleeve coaxial with the rotating hole, and the mating part is in the shape of a convex ring and is located on the outer peripheral wall of the extension sleeve; the rotating member is provided with a receiving groove along the axial direction of the rotating hole, and the limiting part is in the shape of a groove and is located on the inner side wall of the receiving groove, the extension sleeve is inserted into the receiving groove and the mating part is inserted into the limiting part.

[0011] A convex ring-shaped mating part is inserted into a groove-shaped limiting part. The limiting part can constrain the position of the mating part in the axial direction of the rotating hole, thereby constraining the position of the rotating part relative to the sealing part in the axial direction of the rotating hole.

[0012] In some embodiments of this application, the extension sleeve is elastic, and the outer peripheral wall of the extension sleeve is provided with a deformation notch along its own radial direction. The deformation notch penetrates the inner peripheral wall of the extension sleeve and penetrates the end wall of the extension sleeve away from the seal along its own axial direction.

[0013] The deformation notch reduces the structural strength of the extension sleeve, allowing the extension sleeve to undergo elastic bending deformation toward its own axis. This facilitates the extension sleeve to drive the convex ring-shaped mating part into the receiving groove, so that the mating part can be inserted into the limiting part.

[0014] In some embodiments of this application, the inner wall of the liquid storage shell is provided with an output hole, and the end of the rotating sleeve away from the rotating component is provided with an elastic sealing ring. The elastic sealing ring abuts against the inner wall of the liquid storage shell, and the output hole is located inside the elastic sealing ring and communicates with the inside of the rotating sleeve. The accommodating cavity is located inside the rotating sleeve, the liquid inlet hole and the sealing part are located on the outer peripheral wall of the rotating sleeve, and the communicating part penetrates the inner wall of the rotating hole.

[0015] The atomizing core assembly allows the aerosol formed from the aerosol matrix to flow along the rotating sleeve to the output port and be discharged from the output port. When the rotating component is rotated, the elastic sealing ring maintains a sealed connection between the rotating sleeve and the inner wall of the liquid storage shell, reducing the risk of aerosol leakage.

[0016] In some embodiments of this application, one of the rotating member and the sealing member is provided with a positioning part, and the other of the rotating member and the sealing member is provided with a snap-fit ​​part. Two snap-fit ​​parts are provided at intervals along the rotation direction of the rotating member. When the rotating member is rotated, the positioning part can be snapped into the two snap-fit ​​parts in sequence. When the positioning part is snapped into one of the snap-fit ​​parts, the connecting part is connected to the liquid inlet hole. When the positioning part is snapped into the other snap-fit ​​part, the sealing part seals the connecting part.

[0017] The positioning part and the snap-fit ​​part cooperate to restrict the rotation of the rotating part, thereby improving the stability of the connection between the connecting part and the liquid inlet or the stability of the sealing part sealing the connecting part.

[0018] In some embodiments of this application, the rotating component is provided with a condensing chamber and an air inlet. The condensing chamber is connected to the accommodating chamber, and the air inlet is connected to the condensing chamber. The inner wall of the condensing chamber is provided with a liquid-retaining ring, and the air inlet is located inside the liquid-retaining ring.

[0019] The air inlet balances the internal and external air pressure of the containment chamber, facilitating the outward output of aerosols within the containment chamber. The condensation chamber collects un-atomized aerosol matrix or condenses aerosols into liquid form within the containment chamber. A liquid-blocking ring covers the air inlet, reducing the risk of liquid leakage from the condensation chamber through the air inlet.

[0020] In some embodiments of this application, the liquid storage shell is provided with an output nozzle, the interior of which is connected to the accommodating cavity, and the output nozzle is configured to output aerosol; the rotating component is provided with an air inlet channel, which is connected to the condensing cavity and the accommodating cavity, and the orthographic projection of the contour of the end of the air inlet channel connected to the condensing cavity and the inner contour of the liquid baffle ring on a plane perpendicular to the through direction of the output nozzle does not overlap.

[0021] The outline of the end of the air intake channel that connects to the condenser cavity and the outline of the air intake hole do not overlap on the orthographic projection of the plane perpendicular to the through direction of the outlet nozzle. This reduces the possibility of liquid flowing along the inner wall of the air intake channel to the condenser cavity falling into the air intake hole, thereby further reducing the risk of liquid leakage from the air intake hole.

[0022] In some embodiments of this application, the rotating component includes a rotating seat and a rotating housing. The rotating housing is sleeved on the rotating seat. The rotating seat is provided with a receiving cavity, a liquid inlet hole, and a sealing part. The rotating seat and the sealing part are rotatably connected. A condensation cavity is formed between the rotating housing and the rotating seat. The rotating housing is provided with an air inlet hole and a liquid-retaining ring. The peripheral wall of the rotating seat is provided with a sealing ring groove along its own circumference. A sealing ring is embedded in the sealing ring groove and abuts against the inner peripheral wall of the rotating housing.

[0023] The sealing ring can improve the sealing between the rotating seat and the rotating housing, thereby further reducing the possibility of leakage of aerosols or aerosol matrix.

[0024] In some embodiments of this application, the sealing element is provided with a vent hole that communicates with the liquid storage cavity. The sealing element also includes an elastic sealing strip inserted into the vent hole. The elastic sealing strip includes an operating part and a sealing part connected in sequence. The operating part is inserted into the vent hole and is in clearance fit with the vent hole. At least a portion of the sealing part is inserted into the interior of the vent hole near the liquid storage cavity and seals the vent hole. When the sealing part is located inside the liquid storage cavity and detached from the vent hole, the operating part is inserted into the vent hole and at least a portion of the operating part is located outside the vent hole at the end away from the liquid storage cavity.

[0025] When assembling this aerosol bomb, after the aerosol matrix is ​​injected into the storage chamber through the mounting hole, the gas or aerosol matrix in the storage chamber is compressed when the seal is installed on the storage shell, resulting in an increase in the pressure inside the storage chamber. The gas or excess aerosol matrix in the storage chamber can be discharged through the vent hole to balance the internal and external pressure of the storage chamber, thus facilitating the installation of the seal. After the seal is installed, the operating part is pulled to drive the sealing part into the vent hole to seal the vent hole, thereby reducing the risk of aerosol matrix leakage from the vent hole.

[0026] In some embodiments of this application, the peripheral wall of the operating part is provided with a fracture groove, and the operating part can be fractured at the fracture groove.

[0027] During the pulling of the operating part, after the sealing part is inserted into the vent hole and seals the vent hole, the inner wall of the vent hole has a blocking effect on the sealing part, which increases the force on the operating part, causing the operating part to break at the fracture groove. This allows the excess part of the operating part to be removed, thereby reducing the possibility of interference when the operating part is installed into the aerosol device body.

[0028] The embodiments of this application also provide an aerosol device, including an aerosol device body and an aerosol bullet provided in any of the above embodiments. The aerosol device body includes a shell and a power supply disposed within the shell. The liquid storage shell of the aerosol bullet is connected to the shell, and the atomizing core assembly of the aerosol bullet is electrically connected to the power supply.

[0029] Different aerosol flavors can be experienced by replacing the aerosol cartridges. The rotating part of the replaced aerosol cartridge can be rotated to seal the connecting part, thereby reducing the risk of aerosol matrix inside the aerosol cartridge being damaged or leaking.

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] The terms “first”, “second”, etc., used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In this article, the term "connected" means that fluid can flow from one structure to the other. For example, "the inlet and the connecting part are connected" means that fluid in the connecting part can flow to the inlet and fluid in the inlet can flow to the connecting part.

[0047] An embodiment of this application provides an aerosol bomb, including a liquid storage shell, a sealing assembly, and an atomizing core assembly. The liquid storage shell has a liquid storage cavity and a mounting hole, the mounting hole communicating with the liquid storage cavity, and the liquid storage cavity is configured to hold an aerosol matrix. The sealing assembly is connected to the liquid storage shell and seals the mounting hole. The atomizing core assembly is configured to cause the aerosol matrix to form an aerosol. The sealing assembly includes a sealing member and a rotating member. The sealing member is inserted into the mounting hole and connected to the liquid storage shell, and has a connecting portion for the flow of the aerosol matrix, the connecting portion communicating with the liquid storage cavity. At least a portion of the rotating member is located outside the liquid storage shell and rotatably connected to the sealing member. The rotating member has a receiving cavity, a liquid inlet, and a sealing portion, the liquid inlet communicating with the receiving cavity, the sealing portion being configured to seal the connecting portion, and the atomizing core assembly being located within the receiving cavity and connected to the rotating member. When the rotating member is configured to rotate, the connecting portion may communicate with the liquid inlet or be sealed by the sealing portion.

[0048] In use, this aerosol bomb can be rotated to connect the connecting part with the liquid inlet, allowing the aerosol matrix in the storage chamber to flow sequentially along the connecting part and the liquid inlet into the receiving chamber, where it contacts the atomizing core assembly. This allows the atomizing core assembly to atomize the aerosol matrix. Before use, the rotating part can be rotated to seal the connecting part, thus sealing the storage chamber. This reduces the risk of loss or leakage of the aerosol matrix from the connecting part and also reduces the possibility of contamination of the aerosol matrix.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Reference Figure 1 and Figure 2 This application provides an aerosol device 100, which includes an aerosol device body 10 and an aerosol bullet 20. The aerosol device body 10 includes a housing 11 and a power supply (not shown) disposed within the housing 11. The aerosol bullet 20 is detachably disposed within the housing 11. Exemplarily, one end of the housing 11 is provided with a mounting groove 111, and the aerosol bullet 20 is inserted into the mounting groove 111 and snapped into and fixed to the housing 11. It is understood that the power supply is a battery.

[0051] Reference Figure 3 and Figure 4The aerosol bomb 20 includes a liquid storage shell 21, a sealing assembly 22, and an atomizing core assembly 23. The liquid storage shell 21 has a liquid storage cavity 211 and a mounting hole 212, the mounting hole 212 communicating with the liquid storage cavity 211. The liquid storage cavity 211 is configured to hold the aerosol matrix. Exemplarily, the liquid storage shell 21 is a hollow shell with an open end. The liquid storage cavity 211 is formed inside the liquid storage shell 21, and the opening of the liquid storage shell 21 forms the mounting hole 212. The aerosol matrix can be injected into the liquid storage cavity 211 through the mounting hole 212.

[0052] The sealing assembly 22 is connected to the liquid storage shell 21 and seals the mounting hole 212; the atomizing core assembly 23 is connected to the sealing assembly 22 and configured to form an aerosol matrix. In some embodiments, the atomizing core assembly 23 is disposed inside the sealing assembly 22, and includes an atomizing core 231, a liquid guide 232, and an electrode post 233. The electrode post 233 is connected to the sealing assembly 22 and is at least partially exposed. The atomizing core 231 is disposed inside the sealing assembly 22 and electrically connected to the electrode post 233. The liquid guide 232 is sleeve-shaped and is sleeved on and in contact with the atomizing core 231. The liquid guide 232 is configured to contact the aerosol matrix in the liquid storage chamber 211 to conduct the aerosol matrix to the atomizing core 231. In some embodiments, the liquid guide 232 is a cotton wick. In other embodiments, the liquid guiding component 232 may be a structural component such as a ceramic sleeve with capillary pores, as long as the liquid guiding component 232 can conduct the aerosol matrix.

[0053] One end of the liquid storage housing 21, where the sealing assembly 22 is installed, is inserted into the mounting groove 111 (see...). Figure 2 Inside the atomizing core 231, the electrode post 233 is electrically connected to the power supply, enabling the power supply to supply power to the atomizing core 231, thereby allowing the atomizing core 231 to form an aerosol from the aerosol matrix. It is understood that the liquid storage housing 21 is snapped into the outer casing 11. Exemplarily, the mounting groove 111 is provided with contacts, which are electrically connected to the electrodes of the power supply; when the liquid storage housing 21 is installed in the mounting groove 111, the electrode post 233 contacts the contacts, thereby electrically connecting the electrode post 233 to the power supply.

[0054] In some embodiments, the aerosol device 100 (see Figure 2 In some embodiments, the aerosol device 100 can be an electronic cigarette, with the corresponding aerosol matrix being e-liquid and the corresponding atomizing core 231 being a heating wire. In other embodiments, the aerosol device 100 can be a medical atomizer, with the corresponding aerosol matrix being a drug solution and the corresponding atomizing core 231 being an ultrasonic atomizer. In still other embodiments, the aerosol device 100 can also be other types of devices.

[0055] Reference Figure 4 and Figure 5The sealing assembly 22 includes a sealing element 221 and a rotating element 222. The sealing element 221 is inserted into the mounting hole 212. In some embodiments, the sealing element 221 includes a fixing seat 2211 and an elastic sealing sleeve 2212, the elastic sealing sleeve 2212 being sleeved on the end of the fixing seat 2211 near the liquid storage cavity 211. In some embodiments, the elastic sealing sleeve 2212 covers the end of the fixing seat 2211 facing the liquid storage cavity 211 and the peripheral wall of the fixing seat 2211, such that the elastic sealing sleeve 2212 fills the gap between the inner peripheral wall of the liquid storage shell 21 and the peripheral wall of the fixing seat 2211, thereby improving the sealing performance of the connection between the fixing seat 2211 and the liquid storage shell 21. In some embodiments, the elastic sealing sleeve 2212 is made of silicone; in other embodiments, the elastic sealing sleeve 2212 is made of rubber or other materials with elasticity and sealing properties. In other embodiments, the elastic sealing sleeve 2212 may be provided only on the peripheral wall of the fixing base 2211 or the elastic sealing sleeve 2212 may be omitted, as long as it can be ensured that the aerosol matrix in the liquid storage cavity 211 cannot leak from the mounting hole 212.

[0056] In some embodiments, the fixing base 2211 is snapped into the liquid storage shell 21, which can improve the stability of the connection between the fixing base 2211 and the liquid storage shell 21.

[0057] For ease of description, the through direction of the mounting hole 212 is defined as the first direction Z. In some embodiments, the fixing base 2211 is provided with a rotating hole 2211a, which is disposed along the first direction Z and penetrates the end walls of both ends of the fixing base 2211 along the first direction Z. It can be understood that the axial direction of the rotating hole 2211a is parallel to the first direction Z.

[0058] The rotating component 222 and the fixed base 2211 are arranged sequentially along the first direction Z, with the rotating component 222 located outside the liquid storage chamber 211. A rotating sleeve 2221 is provided on the end wall of the rotating component 222 facing the fixed base 2211 along the first direction Z. The rotating sleeve 2221 extends along the first direction Z and is inserted into the rotating hole 2211a. The outer peripheral wall of the rotating sleeve 2221 fits against the inner peripheral wall of the rotating hole 2211a, allowing the rotating sleeve 2221 to rotatably engage with the rotating hole 2211a, thus rotatably connecting the rotating component 222 to the fixed base 2211. The rotating component 222 is provided with a limiting part 2222, and the fixed base 2211 is provided with a mating part 2211b. The limiting part 2222 and the mating part 2211b engage to constrain the position of the rotating component 222 relative to the fixed base 2211 in the axial direction of the rotating hole 2211a, thereby ensuring a stable connection between the rotating component 222 and the fixed base 2211.

[0059] In some embodiments, the inner wall of the liquid storage housing 21 is provided with an output hole 213, which is arranged along the first direction Z and penetrates the outer wall of the liquid storage housing 21. One end of the rotating sleeve 2221 away from the rotating member 222 extends to the outside of the rotating hole 2211a, and an elastic sealing ring 2221a is fitted onto the end of the rotating sleeve 2221 away from the rotating member 222. The elastic sealing ring 2221a abuts against the liquid storage housing 21, and the output hole 213 is located inside the elastic sealing ring 2221a and communicates with the interior of the rotating sleeve 2221. Exemplarily, the inner wall of the liquid storage housing 21 is provided with a fixing tube 214 extending along the first direction Z toward the mounting hole 212. The fixing tube 214 is coaxial with the rotating sleeve 2221, and the output hole 213 is formed inside the fixing tube 214. The elastic sealing ring 2221a abuts against the end wall of the fixing tube 214. When the aerosol matrix is ​​injected into the storage chamber 211 through the mounting hole 212, the fixing tube 214 can prevent the aerosol matrix from leaking out of the output hole 213.

[0060] In some embodiments, the rotating sleeve 2221 forms a receiving cavity 2221b inside, and the atomizing core 231 and the liquid guiding element 232 are disposed in the receiving cavity 2221b. The outer peripheral wall of the rotating sleeve 2221 is provided with a liquid inlet hole 2221c, which communicates with the interior of the rotating sleeve 2221, that is, the liquid inlet hole 2221c communicates with the receiving cavity 2221b. The inner wall of the rotating hole 2211a is provided with a communicating portion 2211c, which is notched and communicates with the liquid storage cavity 211. The liquid inlet 2221c is located inside the rotating hole 2211a. When the rotating component 222 is rotated, the rotating component 222 drives the rotating sleeve 2221 to rotate, so that the liquid inlet 2221c is aligned with the connecting part 2211c, thereby connecting the liquid inlet 2221c with the connecting part 2211c, so that the accommodating cavity 2221b is connected with the liquid storage cavity 211. At this time, the aerosol matrix in the liquid storage cavity 211 can flow along the connecting part 2211c and the liquid inlet 2221c to the accommodating cavity 2221b and contact the liquid guide component 232. The aerosol matrix is ​​conducted to the atomizing core 231 through the liquid guide component 232, so that the aerosol matrix forms an aerosol. The aerosol can flow along the accommodating cavity 2221b to the output hole 213 and be output from the output hole 213.

[0061] The outer peripheral wall of the rotating sleeve 2221 is also provided with a sealing portion 2221d; exemplarily, the sealing portion 2221d is a part of the outer peripheral wall of the rotating sleeve 2221. In other embodiments, the sealing portion 2221d may be an elastic gasket, which may be adhered to or embedded in the outer peripheral wall of the rotating sleeve 2221. Figure 4 and Figure 5 The dashed frame on the rotating sleeve 2221 is used to separate the sealing part 2221d.

[0062] The sealing part 2221d and the connecting part 2211c are arranged sequentially along the rotation direction R of the rotating sleeve 2221. With the liquid inlet 2221c connected to the connecting part 2211c, rotating the rotating component 222 causes the rotating sleeve 2221 to rotate the sealing part 2221d to align with the connecting part 2211c, thus sealing the connecting part 2211c and keeping the liquid storage chamber 211 closed. This reduces the possibility of leakage of the aerosol matrix from the liquid storage chamber 211 through the connecting part 2211c and also reduces the risk of contamination of the aerosol matrix in the liquid storage chamber 211. For example, the aerosol bomb 20 can be installed on the aerosol device body 10 (see...). Figure 2 Before using the aerosol bullet 20, the aerosol bullet 20 should be in the closed state.

[0063] In some embodiments, multiple connecting portions 2211c, liquid inlet holes 2221c, and sealing portions 2221d are provided one-to-one along the rotation direction R. It is understood that the aerosol bomb 20 has an open state and a closed state, and the aerosol bomb 20 can be switched between the open and closed states by rotating the rotating member 222. When the aerosol bomb 20 is in the open state, each connecting portion 2211c is connected to the corresponding liquid inlet hole 2221c; when the aerosol bomb 20 is in the closed state, each sealing portion 2221d seals the corresponding connecting portion 2211c.

[0064] In some embodiments, the inner peripheral wall of the rotating hole 2211a is further provided with a shielding portion 2211d, and the shielding portion 2211d and the communicating portion 2211c are arranged sequentially along the rotation direction R. The shielding portion 2211d is configured to seal the liquid inlet hole 2221c when the sealing portion 2221d seals the communicating portion 2211c. In some embodiments, the shielding portion 2211d is an elastic gasket. Exemplarily, the elastic sealing sleeve 2212 is provided with an extension portion 2212a, which extends into the rotating hole 2211a and covers the inner wall of the rotating hole 2211a; it can be understood that the extension portion 2212a is an elastic gasket and a portion of the extension portion 2212a forms the shielding portion 2211d. Figure 4 and Figure 5 The portion within the dashed box on the extension 2212a is used to separate the shielding portion 2211d.

[0065] In some other embodiments, the extension 2212a may be omitted, and the shield 2211d may be a portion of the inner wall of the rotating hole 2211a.

[0066] Reference Figure 6In some embodiments, the rotating component 222 includes a rotating seat 2223 and a rotating housing 2224. A rotating sleeve 2221 is connected to the end wall of the rotating seat 2223 along the first direction Z, facing the fixed seat 2211. The rotating housing 2224 is sleeved on the rotating seat 2223. A condensation chamber 2223a is formed between the end wall of the rotating seat 2223 along the first direction Z, away from the rotating sleeve 2221, and the rotating housing 2224. The rotating seat 2223 is provided with an air intake channel 2223b along the first direction Z, which connects the accommodating cavity 2221b and the condensation chamber 2223a. Exemplarily, the end of the air intake channel 2223b near the rotating sleeve 2221 is located inside the rotating sleeve 2221.

[0067] In some embodiments, the end wall of the rotating seat 2223 facing the fixed seat 2211 along the first direction Z is provided with a mounting protrusion 2223c. The mounting protrusion 2223c is arranged around the air intake channel 2223b. The rotating sleeve 2221 is sleeved on the mounting protrusion 2223c and is interference-fitted with the mounting protrusion 2223c, so that the rotating sleeve 2221 is stably connected to the rotating seat 2223. In other embodiments, the rotating sleeve 2221 may be integrally injection molded with the rotating seat 2223 or connected by means of bonding or other methods.

[0068] In some embodiments, the peripheral wall of the rotating seat 2223 is provided with a sealing ring groove 2223d along its circumference, and a sealing ring 2223e is embedded in the sealing ring groove 2223d, the sealing ring 2223e abutting against the inner peripheral wall of the rotating housing 2224. Exemplarily, the sealing ring 2223e is made of silicone. The sealing ring 2223e can improve the sealing performance between the rotating seat 2223 and the rotating housing 2224, thereby reducing the possibility of leakage of aerosols or aerosol matrix in the condensation chamber 2223a.

[0069] In some embodiments, the rotating housing 2224 may be omitted, and the condensing cavity 2223a may be located inside the rotating base 2223. An air inlet 2224a is provided on the outer wall of the rotating housing 2224, and the air inlet 2224a communicates with the condensing cavity 2223a. In some embodiments, the air inlet 2224a is located on the bottom wall of the condensing cavity 2223a; the bottom wall of the condensing cavity 2223a is the inner wall of the condensing cavity 2223a facing the air inlet channel 2223b along the first direction Z. The air inlet 2224a can balance the internal and external air pressures of the condensing cavity 2223a and the internal and external air pressures of the accommodating cavity 2221b, so that the aerosol in the accommodating cavity 2221b can be discharged through the outlet 213 (see...). Figure 4 Output. In some other embodiments, the air inlet 2224a may be located on the peripheral wall or top wall of the condenser cavity 2223a.

[0070] The condensation chamber 2223a is used to collect un-atomized aerosol matrix or condensed liquid aerosol within the accommodating chamber 2221b. In some embodiments, the air inlet 2224a is arranged along the first direction Z. The inner wall of the condensation chamber 2223a is provided with a liquid-retaining ring 2224b, the axial direction of which is arranged along the first direction Z; the air inlet 2224a is located inside the liquid-retaining ring 2224b, such that the liquid inlet 2221c is covered by the liquid-retaining ring 2224b, thereby reducing the possibility of leakage of the aerosol matrix within the condensation chamber 2223a through the air inlet 2224a.

[0071] Reference Figure 4 and Figure 6 In some embodiments, the end of the liquid storage housing 21 with the output hole 213 forms an output nozzle 215. It is understood that the interior of the output nozzle 215 is through-type along the first direction Z. Aerosol device 100 (see...) Figure 2 When in use, the output nozzle 215 is inserted into the user's mouth. At this time, the through-path of the output nozzle 215 is approximately vertical, meaning the first direction Z is approximately parallel to the vertical direction. The condensation chamber 2223a is located below the receiving chamber 2221b. For ease of description, a plane perpendicular to the through-path of the output nozzle 215 can be defined as the reference plane 101. It can be understood that the reference plane 101 is perpendicular to the first direction Z. The orthographic projections of the end of the intake channel 2223b that connects to the condenser chamber 2223a and the inner contour of the baffle ring 2224b on the reference plane 101 do not overlap. That is, the end of the intake channel 2223b that connects to the condenser chamber 2223a and the baffle ring 2224b are misaligned in the first direction Z. This makes it difficult for the aerosol matrix flowing into the condenser chamber 2223a along the inner wall of the intake channel 2223b to fall into the baffle ring 2224b under the action of gravity, thereby further reducing the risk of leakage of the aerosol matrix from the intake port 2224a.

[0072] Reference Figure 2 and Figure 3 In other embodiments, the output nozzle 215 may be disposed at one end of the housing 11, and the interior of the output nozzle 215 is provided through the first direction Z; the mounting groove 111 may be disposed on the peripheral wall of the housing 11, and the inner side wall of the mounting groove 111 is provided with a connecting hole, which is connected to the output nozzle 215; after the aerosol bullet 20 is installed in the mounting groove 111, the output hole 213 is connected to the connecting hole, so that the aerosol output from the output hole 213 flows along the connecting hole to the output nozzle 215 and is output from the output nozzle 215.

[0073] Reference Figure 7In some embodiments, the fixed base 2211 is provided with an extension sleeve 2211e coaxial with the rotating sleeve 2221, and the extension sleeve 2211e is provided on the end wall of the fixed base 2211 facing the rotating base 2223 along the first direction Z. The mating part 2211b is in the shape of a convex ring and is provided on the outer peripheral wall of the extension sleeve 2211e. The rotating base 2223 is provided with a receiving groove 2223f along the first direction Z, and the receiving groove 2223f is provided on the end wall of the rotating base 2223 facing the fixed base 2211 along the first direction Z. The limiting part 2222 is in the shape of a groove and is provided on the inner sidewall of the receiving groove 2223f. The extension sleeve 2211e is inserted into the receiving groove 2223f and the mating part 2211b is inserted into the limiting part 2222. It is understood that the end of the rotating sleeve 2221 near the rotating seat 2223 is located in the receiving groove 2223f, and the extension sleeve 2211e is sleeved on the rotating sleeve 2221.

[0074] In some embodiments, the receiving groove 2223f is provided through the second direction X in a through-groove shape, and the limiting part 2222 is provided through the second direction X in a through-groove shape, wherein the second direction X is perpendicular to the first direction Z. The receiving groove 2223f and the limiting part 2222 are through-grooves, which facilitates the injection molding of the receiving groove 2223f and the limiting part 2222.

[0075] A convex ring-shaped mating part 2211b is inserted into a groove-shaped limiting part 2222. The limiting part 2222 can constrain the position of the mating part 2211b in the axial direction of the rotating hole 2211a, thereby constraining the position of the rotating member 222 relative to the sealing member 221 in the axial direction of the rotating hole 2211a.

[0076] In some embodiments, the extension sleeve 2211e is elastic, and its outer peripheral wall is provided with a deformation notch 2211f along its radial direction. The deformation notch 2211f penetrates the inner peripheral wall of the extension sleeve 2211e and also penetrates the end wall of the extension sleeve 2211e at the end away from the fixing seat 2211 along its own axial direction. Exemplarily, the extension sleeve 2211e is made of plastic, which makes the extension sleeve 2211e elastic and possessing a certain structural strength. In some embodiments, multiple deformation notches 2211f are provided, and the multiple deformation notches 2211f are arranged sequentially at intervals along the circumference of the extension sleeve 2211e.

[0077] The deformation notch 2211f reduces the structural strength of the extension sleeve 2211e, allowing it to elastically bend towards its own axis. This facilitates the insertion of the convex ring-shaped mating part 2211b into the receiving groove 2223f, enabling the mating part 2211b to insert into the limiting part 2222. The limiting part 2222, in conjunction with the mating part 2211b, constrains the position of the rotating member 222 relative to the seal 221 in the axial direction of the rotating hole 2211a. This reduces the risk of the rotating sleeve 2221 disengaging from the rotating hole 2211a and causing the rotating member 222 to fall off, thereby improving the stability of the rotational connection between the rotating member 222 and the seal 221.

[0078] In some embodiments, one of the rotating member 222 and the sealing member 221 is provided with a positioning portion 2223g, and the other of the rotating member 222 and the sealing member 221 is provided with a locking portion 2211g. Two locking portions 2211g are spaced apart along the rotation direction R of the rotating member 222. When the rotating member 222 is rotated, the positioning portion 2223g can sequentially engage with the two locking portions 2211g to restrict the rotation of the rotating seat 2223. Exemplarily, the locking portion 2211g is protruding and is located on the outer peripheral wall of the extension sleeve 2211e; the positioning portion 2223g is recessed and is located on the inner wall of the receiving groove 2223f.

[0079] When the positioning part 2223g is engaged with one of the engagement parts 2211g, the aerosol bullet 20 (see...) Figure 4 When the positioning part 2223g is inserted into another locking part 2211g, the aerosol bullet 20 is in the open state; when the positioning part 2223g is inserted into another locking part 2211g, the aerosol bullet 20 is in the closed state. By cooperating with the locking part 2211g, the rotation of the rotating part 222 can be restricted, thereby improving the stability of the aerosol bullet 20 in maintaining the open or closed state.

[0080] In other embodiments, the snap-fit ​​portion 2211g may be in the shape of a groove, and the positioning portion 2223g may be in the shape of a protrusion. The positioning portion 2223g may be provided on the end wall of the fixed seat 2211 along the first direction Z towards the rotating seat 2223, and the snap-fit ​​portion 2211g may be provided on the end wall of the rotating seat 2223 along the first direction Z towards the fixed seat 2211.

[0081] Reference Figure 8 and Figure 9In some embodiments, the mounting base 2211 is provided with a vent 2211h, which communicates with the liquid storage chamber 211. In some embodiments, the vent 2211h extends through the mounting base 2211 along the first direction Z. When assembling the aerosol bomb 20, the aerosol matrix is ​​injected into the liquid storage chamber 211 through the mounting hole 212, and then the mounting base 2211 is installed in the mounting hole 212. The gas or excess aerosol matrix in the liquid storage chamber 211 can be discharged through the vent 2211h to balance the internal and external pressures of the liquid storage chamber 211, thereby facilitating the installation of the mounting base 2211.

[0082] The seal 221 also includes an elastic sealing strip 2213, which is inserted into the vent 2211h and configured to seal the vent 2211h. For example, the elastic sealing strip 2213 is made of silicone.

[0083] The elastic sealing strip 2213 includes an operating part 2213b and a sealing part 2213a connected in sequence. The end of the operating part 2213b away from the sealing part 2213a is separated from the rotating seat 2223 by the fixed seat 2211 (see...). Figure 7 One side of the sealing part 2213a is inserted into the exhaust hole 2211h, and the operating part 2213b is clearance-fitted with the exhaust hole 2211h. The sealing part 2213a is configured to seal the exhaust hole 2211h. It can be understood that both the sealing part 2213a and the operating part 2213b are elongated, and the area of ​​the cross-section of the sealing part 2213a perpendicular to its own length direction is larger than the area of ​​the cross-section of the operating part 2213b perpendicular to its own length direction, that is, the sealing part 2213a and the operating part 2213b are thicker.

[0084] During the installation of the mounting base 2211, the gas or excess aerosol matrix in the liquid storage chamber 211 can be discharged through the gap between the inner wall of the vent hole 2211h and the operating part 2213b. When the mounting base 2211 is inserted into the mounting hole 212, the sealing part 2213a is located in the liquid storage chamber 211 and at least part of the operating part 2213b is located outside the end of the vent hole 2211h away from the liquid storage chamber 211. At this time, the operating part 2213b is pulled in the first direction Z away from the liquid storage chamber 211. The operating part 2213b can drive the sealing part 2213a to be inserted into the interior of the vent hole 2211h near the end of the liquid storage chamber 211 to seal the vent hole 2211h.

[0085] In some embodiments, the peripheral wall of the operating part 2213b is provided with a fracture groove 2213c, which is located at one end of the operating part 2213b near the sealing part 2213a. For example, when the sealing part 2213a is inserted into the vent hole 2211h, the fracture groove 2213c is located inside the vent hole 2211h. During the pulling of the operating part 2213b, after the sealing part 2213a is inserted into and seals the vent hole 2211h, the inner wall of the vent hole 2211h provides resistance to the sealing part 2213a, increasing the force on the operating part 2213b. This causes the operating part 2213b to break at the fracture groove 2213c, allowing the excess portion of the operating part 2213b to be removed. In some other embodiments, the fracture groove 2213c may be omitted, and the fixing seat 2211 may be provided with a receiving groove 2211j, which can be bent and stored in the receiving groove 2211j. Alternatively, a tool can be used to cut off the excess part outside the external vent hole 2211h of the operating part 2213b.

[0086] In some embodiments, the elastic sealing strip 2213 further includes a blocking portion 2213d, which is connected to the end of the sealing portion 2213a away from the operating portion 2213b. The area of ​​the cross-section of the blocking portion 2213d perpendicular to the length direction of the sealing portion 2213a is larger than the area of ​​the cross-section of the sealing portion 2213a perpendicular to its own length direction. During the movement of the sealing portion 2213a toward the vent hole 2211h, the blocking portion 2213d can abut against the end wall of the fixed seat 2211 toward the liquid storage chamber 211, thereby reducing the possibility that the sealing portion 2213a will be pulled out of the vent hole 2211h and detach from the vent hole 2211h.

[0087] Reference Figure 10 and Figure 11 In some embodiments, the rotating member 222 may be a hollow shell, and the interior of the rotating member 222 forms a receiving cavity 2221b, in which the atomizing core assembly 23 is disposed. The liquid inlet 2221c and the sealing portion 2221d are disposed on the end wall of the rotating member 222 along the first direction Z toward the fixed base 2211; it is understood that the sealing portion 2221d may be a portion of the end wall of the rotating member 222 or a gasket embedded in the end wall of the rotating member 222. The connecting portion 2211c is a through hole, and the connecting portion 2211c penetrates the end walls of both ends of the sealing member 221 along the first direction Z, so that the connecting portion 2211c communicates with the liquid storage cavity 211.

[0088] The rotating member 222 can be rotated to a state where the connecting portion 2211c is aligned with the liquid inlet 2221c, so that the connecting portion 2211c and the liquid inlet 2221c are connected, allowing the aerosol matrix in the storage chamber 211 to flow along the connecting portion 2211c and the liquid inlet 2221c into the receiving chamber 2221b. When the rotating member 222 is rotated in the state where the connecting portion 2211c is connected to the liquid inlet 2221c, the liquid inlet 2221c can be misaligned with the liquid inlet 2221c, and the sealing portion 2221d is aligned with the connecting portion 2211c in the first direction Z, so that the sealing portion 2221d seals the connecting portion 2211c, thereby keeping the storage chamber 211 in a closed state.

[0089] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
