Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0029] In this application, the terms "installed," "disposed," "provided with," "connected," "slidingly connected," and "fixed" should be interpreted broadly. For example, "connected" or "coupled" can refer to a fixed connection, a removable connection, or an integral structure; a mechanical connection or an electrical connection; a direct connection, an indirect connection through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the use of these terms in this application based on the specific circumstances.

[0030] The term "plurality" as used herein includes two or more.

[0031] The present application provides an atomizing device for heating an atomizing matrix to generate an aerosol. The atomizing device includes a power supply component (not shown in the figure) and an atomizer 1. The power supply component and the atomizer 1 are electrically connected to each other, which can increase the power supply required for the operation of the atomizer 1 and can control and adjust the operation of the atomizer 1. The power supply component and the atomizer 1 are detachably connected to each other, which can prevent the atomized matrix in the atomizer 1 from leaking and damaging or corroding the power supply component during transportation. The connection method between the power supply component and the atomizer 1 includes plug-in connection, threaded connection or magnetic connection.

[0032] The power supply assembly is prior art and will not be described in detail here. The focus of this application, namely the atomizer 1, will be specifically introduced below.

[0033] When explaining the atomizer 1 in detail, the object of its heating, namely the atomizing matrix, is first described in detail. The atomizing matrix refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols, such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as mono-, di-, or triacetate of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanoic acid. The atomizing matrix is typically in liquid form and stored in a container or stored by a porous structure such as liquid storage cotton or porous ceramics.

[0034] As used herein, an aerosol refers to a dispersion of solid or liquid particles in a gas. Aerosols are generally used to refer to substances that have been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form containing suspended solid or liquid drug particles.

[0035] See also Figures 1 to 7 The atomizer 1 includes a housing 11 , an atomizing assembly 12 , a movable part 13 and a driving part 14 .

[0036] The shell 11 can be a structure composed of a plurality of components, and a plurality of different cavities can be formed inside the shell 11 to facilitate the installation of different components. For example, the inside of the shell 11 has a liquid storage chamber 111 and a mounting chamber 112, the liquid storage chamber 111 is used to store the atomized matrix, the mounting chamber 112 is used to install the atomizing assembly 12, and the atomizing assembly 12 is used to heat the atomized matrix to form an aerosol, and the liquid storage chamber 111 and the mounting chamber 112 can be coaxially arranged and isolated from each other. Based on the use characteristics of the atomizer 1, the mounting chamber 112 is arranged inside the liquid storage chamber 111, that is, the liquid storage chamber 111 is arranged around the mounting chamber 112 and the atomizing assembly 12, and the liquid storage chamber 111 provides the atomizing matrix, which is the heating object when the atomizing assembly 12 is working. Therefore, under normal circumstances, the liquid storage chamber 111 should have a liquid path structure connected to the atomizing assembly 12, and the liquid path structure includes a liquid inlet 121 arranged on the atomizing assembly 12. There may be multiple liquid inlets 121 , which are evenly arranged so that the atomized matrix flows evenly into the atomizing assembly 12 .

[0037] When the atomizing device is in use, the mounting cavity 112 is in communication with the outside, and the atomized matrix may leak through the atomizing assembly 12 and the mounting cavity 112, or through the assembly gap between the atomizing assembly 12 and the liquid storage cavity 111, the housing 11, etc. At least part of the structure of the movable member 13 is arranged inside the housing 11 to block the liquid storage cavity 111, and at least part of the structure is movably sleeved on the outside of the atomizing assembly 12. The driving member 14 is connected to the movable member 13, and the driving member 14 can drive the movable member 13 to move relative to the atomizing assembly 12, so that the movable member 13 can cover or open the liquid inlet 121, so as to isolate or connect the liquid storage cavity 111 with the atomizing assembly 12. During the transportation of the atomizer 1, the driving member 14 drives the movable member 13 to block the liquid inlet 121, so that the liquid storage chamber 111 and the atomizing assembly 12 are isolated, that is, the liquid core is separated, thereby preventing the atomized matrix from entering the atomizing assembly 12 and preventing the atomized matrix from leaking through the atomizing assembly 12. When the atomizer 1 is in use, the driving member 14 drives the movable member 13 to open the liquid inlet 121, so that the atomizer 1 is activated to achieve liquid core contact, and the liquid storage chamber 111 can continuously provide the heating object, that is, the atomizing matrix, to the atomizing assembly 12, thereby ensuring the normal operation of the atomizer 1, thereby improving the user experience.

[0038] Since the movable part 13 is arranged between the shell 11 and the atomizer assembly 12, the movable part 13 can not only block the liquid storage chamber 111, but also seal the space between the atomizer assembly 12 and the shell 11, and can seal the atomized matrix in the liquid storage chamber 111, and can also improve the sealing effect of the atomizer 1, further effectively preventing the atomized matrix from leaking from the assembly gap between the components.

[0039] In order to increase the capacity of the nebulizer 1 and realize multiple reuse of the nebulizer 1, a liquid injection port that can be communicated with the liquid storage chamber 111 can be provided on the shell 11, and the liquid storage chamber 111 can be replenished with aerosol matrix through an external container.

[0040] In some embodiments, the movable member 13 and the driving member 14 are detachably connected. After the liquid core is in contact, the driving member 14 can be removed to facilitate the installation of the power supply assembly. In this embodiment, the movable member 13 is arranged at one end of the housing 11, and the movable member 13 and the atomizing assembly 12 are wrapped, which can further enhance the sealing effect. The movable member 13 is made of silicone with good sealing performance. It has a certain elasticity and can seal the entire assembly gap, and is low in cost and easy to process, so that when the driving member 14 is used as a disposable consumable, it also has a relatively controllable cost. In this embodiment, the movable member 13 is coaxial with the atomizing assembly 12 and the housing 11, and the movable member 13 moves along the axis direction during the movement to avoid eccentricity (the movable member 13 is not coaxial with the atomizing assembly 12 and the housing 11) affecting the sealing effect.

[0041] Of course, in some other embodiments, the movable part 13 and the driving part 14 are fixedly connected and are an integrally formed structure. Through the driving part 14, not only can the movable part 13 be switched from blocking the liquid inlet 121 to opening the liquid inlet 121, but the reverse operation can also be performed to switch from opening the liquid inlet 121 to blocking the liquid inlet 121, which can facilitate the mutual switching between liquid core separation and liquid core contact, and effectively ensure that the atomizer 1 has good sealing during the entire use process (including the process of stopping use after the first activation).

[0042] See also Figure 4 and Figure 5 In some embodiments, the movable part 13 has a mounting portion 131, and the driving part 14 includes a connecting portion 141 and a driving portion 142. The driving portion 142 is connected to the connecting portion 141, and one end of the connecting portion 141 away from the driving portion 142 is detachably connected to the mounting portion 131. The connecting portion 141 and the driving portion 142 can be an integrally formed structure. Of course, the connecting portion 141 and the driving portion 142 can also be independent parts that are fixed into an integral structure by assembly. The mounting portion 131 is symmetrically provided with two along the axis of the movable part 13, and the connecting portion 141 is also correspondingly provided with two. Of course, in some other embodiments, the number of mounting portions 131 and connecting portions 141 is not limited to two. The mounting portion 131 is evenly arranged along the circumference of the movable part 13, and the connecting portion 141 corresponds to the mounting portion 131, so that the movable part 13 is evenly stressed, avoiding uneven stress that causes the movable part 13 to be eccentric with the atomizer assembly 12 and the housing 11 and affects the sealing.

[0043] To effectively connect the connecting portion 141 and the mounting portion 131, the connecting portion 141 is provided with a mounting groove 1411, into which the mounting portion 131 is mounted. The shape and size of the mounting groove 1411 can be consistent with those of the mounting portion 131, so that the mounting portion 131 can be positioned and fixed by the mounting groove 1411. After the driving member 14 drives the movable member 13 into position to achieve liquid core contact, the provision of the mounting groove 1411 also facilitates the removal of the driving member 14.

[0044] To further facilitate the detachment of the driving member 14 and the movable member 13, the connecting portion 141 has a break structure 1412. The wall of the mounting groove 1411 is recessed toward the side away from the driving member 142, and the end of the connecting portion 141 away from the driving member 142 is recessed toward the side closer to the driving member 142, forming the break structure 1412. The portion of the mounting portion 131 facing the break structure 1412 has a puncture structure 1311. The puncture structure 1311 can be broken by an external force, thereby facilitating the separation of the connecting portion 141 from the mounting portion 131. Specifically, after the driving member 14 drives the movable member 13 into position, the unique structural design of the break structure 1412 allows it to be easily broken by a sudden application of a large force, thereby achieving the removal of the driving member 14. In this embodiment, the puncture structure 1311 is a cone or a multi-sided pyramid. Preferably, the puncture structure 1311 is a triangular pyramid structure, and the cross-section of the puncture structure 1311 along the axial direction of the shell 11 can be a triangular structure. The breaking structure 1412 is two symmetrical triangular structures, so that the size of the middle part of the breaking structure 1412 (the size along the axial direction of the shell 11) is smaller, which is convenient for breaking.

[0045] A movable groove 113 is provided on the side wall of the housing 11. The mounting portion 131 is movably disposed within the movable groove 113. The movable groove 113 extends along the axial direction of the housing 11. The driving member 14 is capable of driving the movable member 13 to move along the axial direction of the housing 11. The provision of the movable groove 113 can guide the movement of the movable member 13, ensuring smooth movement of the movable member 13 and preventing the movement of the movable member 13 from affecting the sealing of the atomizer 1.

[0046] See also Figure 3 In some embodiments, the movable groove 113 is provided through the side wall of the housing 11, the mounting portion 131 extends to the outside of the housing 11 through the movable groove 113, and the connecting portion 141 is clamped in the movable groove 113 and connected to the mounting portion 131. Since the mounting portion 131 extends outside the housing 11, the connecting portion 141 is provided on the outside of the housing 11. On the one hand, the driving portion 142 and the connecting portion 141 cooperate to seal the housing 11 and achieve a sealing effect. On the other hand, it facilitates the removal and installation of the connecting portion 141. Of course, in some other embodiments, the movable groove 113 can also be provided on the inner wall of the housing 11, and the movable groove 113 only provides a guide for the movable member 13.

[0047] In order to further enhance the sealing effect, the atomizer 1 further comprises a housing base 15, at least part of which is inserted into the housing 11 and disposed on one side of the atomizer assembly 12. The movable member 13 is disposed between the housing 11 and the housing base 15. The housing base 15, the housing 11, the atomizer assembly 12 and the movable member 13 cooperate to define a well-sealed liquid storage chamber 111. In order to prevent the movable member 13 from slipping out of the housing 11 and causing the seal to fail, a first limiting portion 132 is provided on the movable member 13, and a second limiting portion 151 is provided on the housing base 15. When the movable member 13 moves to open the liquid inlet 121, the first limiting portion 132 and the second limiting portion 151 abut against each other.

[0048] Since the movable part 13 is sleeved on the outside of the atomizer assembly 12, there is a certain friction between the movable part 13 when it moves. This friction may drive the atomizer assembly 12 to move, which may damage the entire atomizer 1. The atomizer assembly 12 and the mounting cavity 112 have an interference fit, so that the atomizer assembly 12 and the mounting cavity 112 are tightly connected, preventing the atomizer assembly 12 from moving with the movable part 13.

[0049] In order to increase the friction between the atomizer assembly 12 and the mounting cavity 112 and at the same time improve the sealing between the atomizer assembly 12 and the mounting cavity 112, the atomizer 1 also includes a sealing top cover 16, which is arranged between the atomizer assembly 12 and the mounting cavity 112. The sealing top cover 16 is made of silicone and can not only seal the gap between the mounting cavity 112 and the atomizer assembly 12, but also use the friction between it and the atomizer assembly 12 to fix the atomizer assembly 12 to prevent the atomizer assembly 12 from moving or even falling.

[0050] The atomizer 1 also includes a mouthpiece 114, which is formed on the housing 11 and is in communication with the mounting cavity 112. The mounting cavity 112 can not only be used to install and fix the atomizer assembly 12, but also enables the mouthpiece 114 to communicate with the inside of the atomizer assembly 12, forming a communicating air path inside the mouthpiece 114, the mounting cavity 112, and the atomizer assembly 12, so that the aerosol flows along the air path to the mouthpiece 114. Since the mouthpiece 114 is in communication with the atomizer assembly 12, there is a possibility that the atomized matrix will leak from the mouthpiece 114. The atomizer 1 also includes a sealing plug 17, which is detachably provided on the mouthpiece 114 for sealing the mouthpiece 114. Since the sealing plug 17 is detachably connected to the mouthpiece 114, the sealing plug 17 can be removed when the atomizer 1 is activated for use. When the movable member 13 moves relative to the atomizer assembly 12 along the axis of the housing 11 and relatively away from the mouthpiece 114, it can switch from blocking the liquid inlet 121 to opening the liquid inlet 121, so that the atomizer 1 is activated and in the liquid core contact state. In some other embodiments, the movable member 13 can also move in the opposite direction, that is, relative to the atomizer assembly 12 along the axis of the housing 11, relatively close to the mouthpiece 114, so that the atomizer 1 is in the liquid core separation state, thereby realizing the free switching of the atomizer 1 between the liquid core separation and the liquid core contact state.

[0051] Furthermore, the housing base 15 is arranged at one end of the housing 11 away from the suction nozzle 114, and a liquid-absorbing cotton 18 is also provided between the housing base 15 and the atomizing assembly 12 for collecting the atomized matrix. At least part of the structure of the driving member 14 is sleeved on the outside of the housing base 15. In order to further improve the sealing effect, a sealing member 19 is provided on the outside of the housing base 15. The sealing member 19 is an O-ring. When the liquid core contacts, the sealing member 19 is arranged between the housing base 15 and the movable member 13 to provide a sealing effect. The side of the O-ring is a smooth arc surface, which can reduce friction and avoid interfering with the relative movement of the movable member 13 and the housing base 15.

[0052] The atomizer assembly 12 includes an atomizer tube 122, a heating element 123, an atomizer base 124, an inner cotton packing 125 and a liquid storage part 126. At least part of the structure of the atomizer tube 122 is arranged in the installation cavity 112 and is connected to the suction nozzle part 114. The liquid inlet 121 is formed on the side wall of the atomizer tube 122. The heating element 123 is arranged in the atomizer tube 122. The atomizer base 124 is arranged at the end of the atomizer tube 122 away from the suction nozzle part 114, and is used to seal the end of the atomizer tube 122 away from the suction nozzle part 114. At least part of the structure of the movable part 13 is movably sleeved on the outside of the atomizer tube 122. The liquid reservoir 126 is disposed on the inner wall of the atomizing tube 122. The inner cotton 125 is disposed on the side of the liquid reservoir 126 away from the inner wall of the atomizing tube 122. The heating element 123 is disposed on the inner cotton 125. The atomized substrate enters the liquid reservoir 126 through the liquid inlet 121, passes through the inner cotton 125, and is heated by the heating element 123 thereon. The heating element 123 can be a mesh heating sheet, or alternatively, a heating tube or heating wire.

For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
