Patent Description:
An electronic atomization device in the art generally includes an atomizer and a battery. An atomization core may be configured inside the atomizer. The atomization core may heat and atomize a substrate. The atomization core has a service life. When the user needs to replace the atomization core in the atomizer, the user may need to rotate to disengage a connection structure and remove the atomization core or directly pull out the atomization core.

However, this is a simple way to take out the atomization core, which may be easily operated by children. In this way, it is highly possible that children may open the atomizer and contact the substrate therein, even resulting in accidental ingestion of the substrate. Atomizers are known from <CIT>, <CIT> and <CIT>.

The present application provides an atomizer and an electronic atomization device to solve the problem that the atomization core may be easily disassembled from the atomizer and harmful to vulnerable people, such as children.

According to an aspect of the present disclosure, an atomizer is provided. The atomizer includes: a liquid storage assembly and a mouthpiece assembly. The atomizer includes an inner barrel, and the inner barrel defines a slide cavity for receiving an atomization core assembly. The mouthpiece assembly is disposed at an end of the inner barrel for pushing against the atomization core assembly, the atomization core assembly is capable of sliding relative to the inner barrel, and an end of the atomization core assembly is capable of being exposed to an outside of the atomizer.

According to another aspect of the present disclosure, an electronic atomization device is provided and includes a body assembly and the atomizer as described in the above. The body assembly is connected to the atomizer and is configured to supply power for the atomizer.

According to still another aspect of the present disclosure, an atomizer is provided and includes an atomization core assembly, a liquid storage assembly, and a mouthpiece assembly. The atomization core assembly is configured to atomize liquid. The liquid storage assembly defines a receiving channel, and the atomization core assembly is received in the receiving channel. The mouthpiece assembly is disposed at a first end of the liquid storage assembly. The mouthpiece assembly is configured to push the atomization core assembly to slide the atomization core assembly in the receiving channel, and an end of the atomization core assembly is capable of being exposed to an outside of the atomizer through a second end of the liquid storage assembly opposite to the first end.

The present disclosure provides an atomizer and an electronic atomization device. An atomization core assembly may be configured in a slide cavity of an inner barrel, and a mouthpiece assembly may be configured to abut against and push the atomization core assembly to slide the atomization core assembly along the slide cavity of the inner barrel, such that an end of the atomization core assembly may be exposed to an outside. The user may remove the atomization core assembly from the atomizer by holding the exposed end of the atomization core assembly. In this way, when the end of the atomization core assembly is not exposed, the user may not take out the atomization core assembly, which may effectively reduce the occurrence of children and other vulnerable people taking out the atomization core assembly, causing hazards to themselves. Therefore, special skills may be required to dissemble the atomization core assembly from the atomizer provided in the present disclosure, which increases difficulty for children and other vulnerable people to disassemble the atomization core assembly, and effectively reduce the occurrence of children and other vulnerable people easily taking out the atomization core assembly and causing hazards to themselves.

The atomizer <NUM> may be configured to store a liquid and atomize the liquid to generate smoke that can be inhaled by a user. The liquid may be liquid matrix, such as an e-liquid, a medicinal liquid, and the like. The body assembly <NUM> may be configured to supply power for the atomizer <NUM> to enable the atomizer <NUM> to atomize the e-liquid to generate the smoke.

In the present embodiment, the e-liquid may be taken as an example for illustration.

As shown in <FIG>, the atomizer <NUM> may include a liquid storage assembly <NUM>, a mouthpiece assembly <NUM>, an atomizer core assembly <NUM>, and an end cap assembly <NUM>.

The atomizer core assembly <NUM> may be configured to atomize the e-liquid to generate the smoke. The mouthpiece assembly <NUM> may be connected to the liquid storage assembly <NUM>. Cavities of the mouthpiece assembly <NUM>, the liquid storage assembly <NUM>, and the atomization core assembly <NUM> may be communicated with each other, such that the user may inhale the smoke generated by the atomization core assembly <NUM> through the mouthpiece assembly <NUM>. The end cap assembly <NUM> may be connected to an end of the liquid storage assembly <NUM> opposite to the mouthpiece assembly <NUM>. The end cap assembly <NUM> may cover the receiving channel <NUM>.

The liquid storage assembly <NUM> may include an outer barrel <NUM>, an inner barrel <NUM>, a base <NUM> and a top cap <NUM>. The base <NUM> and the top cap <NUM> may be connected to the two ends of the outer barrel <NUM>. The outer barrel <NUM> may sleeve the inner barrel <NUM> and may be connected between the base <NUM> and the top cap <NUM>. A liquid storage cavity <NUM> may be defined between the outer barrel <NUM> and the inner barrel <NUM>. The liquid storage cavity <NUM> may be defined to store the e-liquid.

As shown in <FIG>, the inner barrel <NUM> defines a slide cavity <NUM>. An end of the inner barrel <NUM> away from the mouthpiece assembly <NUM> is provided with the base <NUM>. The base <NUM> may define an embedding channel <NUM>. The slide cavity <NUM> and the embedding channel <NUM> are communicated. The receiving channel <NUM> may include the slide cavity <NUM> and the embedding channel <NUM>. The atomization core assembly <NUM> may be entirely received in the slide cavity <NUM> and the embedding channel <NUM>.

In other embodiments, the base <NUM> sleeves an outer periphery of the inner barrel <NUM> and limits a position of the inner barrel <NUM> along an axial direction. The slide cavity <NUM> may serve as the receiving channel <NUM>, and the atomization core assembly <NUM> may be entirely received in the slide cavity <NUM>. Alternatively, the top cover <NUM> may define a receiving chamber, and the slide cavity <NUM> may be communicated with the receiving chamber. The slide cavity <NUM> and the receiving chamber may cooperatively serve as the receiving channel <NUM>. Alternatively, the embedding channel <NUM>, the slide cavity <NUM> and the receiving chamber of the top cover <NUM> may cooperatively serve as the receiving channel <NUM>.

In the present disclosure, the liquid storage assembly <NUM> defines the receiving channel <NUM>. The receiving channel <NUM> may be defined to receive the entire atomization core assembly <NUM>, that is, all components of the atomization core assembly <NUM> may be received in the receiving channel <NUM>. The atomization core assembly <NUM> is received in the receiving channel <NUM> in a drop-preventing manner. In other words, the atomization core assembly <NUM> may not slide in the receiving channel <NUM> arbitrarily to be released from the receiving channel <NUM>. A size of an end of the receiving channel <NUM> may match with a size of an end of the atomization core assembly <NUM>. That is, the size of the end of the receiving channel <NUM> may approximately be the same as the size of the end of the atomization core assembly <NUM>. Therefore, children may not be able to use fingers to reach an inside of the receiving channel <NUM> and pull the atomization core assembly <NUM>. The children may be prevented from accidentally separating the atomization core assembly <NUM> from the receiving channel <NUM>, causing the e-liquid to leak. The occurrence of the children accidentally contacting and ingesting the e-liquid may be reduced.

As shown in <FIG>, the atomization core assembly <NUM> may include a substrate <NUM>, an atomization element <NUM> and an electrode <NUM>. The atomization element <NUM> and the electrode <NUM> may be mounted on the substrate <NUM>. The electrode <NUM> may be electrically connected to the atomization element <NUM>. The atomization element <NUM> may include a liquid guiding member and an atomization member. The liquid guiding member may be liquid guiding cotton or liquid guiding fiber, and the like. The atomization member may be a heating mesh or a resistance wire, and the like. The atomization member may be electrically connected to the electrode. The atomization member may be configured to atomize the e-liquid guided by the liquid guiding member. The atomization element <NUM> may be porous ceramic silicon, which will not be limited by the present disclosure.

As shown in <FIG>, the end cap assembly <NUM> may be connected to the base <NUM>. The end cap assembly <NUM> may seal the receiving channel <NUM> to cover the atomization core assembly <NUM>, such that the children may be protected from contacting the atomization core assembly <NUM>.

In the present embodiment, a thread may be configured at an outer circumference of the base <NUM>. The end cap assembly <NUM> and the base <NUM> may be threadedly connected. The atomization core assembly <NUM> may be electrically connected to the end cap assembly <NUM>, and power may be supplied to the atomization core assembly <NUM> through the end cap assembly <NUM>. Specifically, the end cap assembly <NUM> may include an electrode. After the end cap assembly <NUM> is connected to the base <NUM>, the electrode of the end cap assembly <NUM> may be electrically connected to the electrode <NUM> of the atomization core assembly <NUM>.

Therefore, the end cap assembly <NUM> may further be configured to connect to the base <NUM> and cover the atomization core assembly <NUM> to further isolate the atomization core assembly <NUM>, such that the children may be protected from accidentally operating the device, causing the e-liquid to leak, and protected from accidentally ingesting the e-liquid.

In other embodiments, the atomizer <NUM> may not include the end cap assembly <NUM>, and the structure of the atomizer <NUM> shown in <FIG> may be applied.

In the present embodiment, as shown in <FIG>, both the base <NUM> and the top cover <NUM> may be detachably connected to the outer barrel <NUM>, and both the base <NUM> and the top cover <NUM> may be detachably connected to the inner barrel <NUM>. For example, the connection may be thread connection or buckled connection via a sealing member, and the like. In other embodiments, the top cover <NUM>, the outer barrel <NUM> and the inner barrel <NUM> may be configured as an integral overall structure. Alternatively, the base <NUM>, the outer barrel <NUM> and the inner barrel <NUM> may be configured as an integral overall structure. Alternatively, the top cover <NUM> and the inner barrel <NUM> may be configured as an integral overall structure. The present disclosure does not limit the integrity of the above components.

The top cover <NUM> may define a guide cavity <NUM>. An internal thread may be configured at an end of the top cover <NUM> facing the inner barrel <NUM>. An external thread may be configured on an outer circumference of the inner barrel <NUM>. The top cover <NUM> may be threadedly connected to the inner barrel <NUM>. The mouthpiece assembly <NUM> may be configured at an end of the inner barrel <NUM>, extend through the guide cavity <NUM>, and may be guided by the guide cavity <NUM>. A cavity of the mouthpiece assembly <NUM> may be communicated with an atomization chamber <NUM> in the atomization core assembly <NUM>, such that the user may inhale the smoke in the atomization chamber <NUM> through the mouthpiece assembly <NUM>.

In the present disclosure, the mouthpiece assembly <NUM> may further be configured to abut against and push the atomizer core assembly <NUM>, such that the atomizer core assembly <NUM> may slide relative to the inner barrel <NUM>, and an end of the atomizer core assembly <NUM> may be exposed to an outside from the end of the receiving channel <NUM>. In this way, the atomizer core assembly <NUM> may be released from the receiving channel <NUM> by pulling the exposed end of the atomizer core assembly <NUM>.

The atomizer <NUM> may further include an elastic member <NUM>. An end of the elastic member <NUM> may abut against the mouthpiece assembly <NUM>. The elastic member <NUM> may be elastically compressed while the mouthpiece assembly <NUM> pushes against the atomizer core assembly <NUM>. The compressed elastic member <NUM> may be configured to push against the mouthpiece assembly <NUM> to reset, after an external force applied on the mouthpiece assembly <NUM> is removed.

The elastic member <NUM> may be a spring or an elastic sleeve, and the like.

The mouthpiece assembly <NUM> may include a mouthpiece <NUM>, a stop sleeve <NUM> and a slide sleeve <NUM>. An end of the elastic member <NUM> may abut against the mouthpiece <NUM>. An end of the stop sleeve <NUM> may be connected to the mouthpiece <NUM>. The other end of the stop sleeve <NUM> may be configured to be stopped to limit a position of the stop sleeve <NUM> when the mouthpiece <NUM> is reset. The slide sleeve <NUM> may be received in the slide cavity <NUM> and may be detachably connected to the atomization core assembly <NUM>. The mouthpiece <NUM> may be driven by an external force to drive the stop sleeve <NUM> to push against the slide sleeve <NUM>, such that the end of the atomization core assembly <NUM> may be exposed to the outside from the end of the receiving channel <NUM>. After separating the atomization core assembly <NUM> and the slide sleeve <NUM>, the elastic member <NUM> may provide elasticity to reset the mouthpiece <NUM> and the stop sleeve <NUM>.

As shown in <FIG>, the mouthpiece <NUM> may define a first smoke channel <NUM>, the stop sleeve <NUM> may define a second smoke channel <NUM>, and the slide sleeve <NUM> may define a third smoke channel <NUM>. The first smoke channel <NUM>, the second smoke channel <NUM>, the third smoke channel <NUM> and the atomization chamber <NUM> may be communicated. The smoke generated in the atomization chamber <NUM> may successively flow through the third smoke channel <NUM>, the second smoke channel <NUM> and the first smoke channel <NUM>, reaching an oral of the user.

As shown in <FIG>, in the present embodiment, a stop ring <NUM> may be configured on an inner wall of the guide cavity <NUM>. The elastic member <NUM> may be elastically compressed between the mouthpiece <NUM> and the stop ring <NUM>. The mouthpiece <NUM> may extend and retract along the guide cavity <NUM>. The stop sleeve <NUM> may extend through the stop ring <NUM>. The other end of the stop sleeve <NUM> may be disposed on a side of the stop ring <NUM> away from the elastic member <NUM> and may be engaged with the stop ring <NUM> for position-limiting.

As shown in <FIG>, the stop sleeve <NUM> may include a sleeve body <NUM> and a limitation ring <NUM> disposed on an outer circumference of the sleeve body <NUM>. An end of the sleeve body <NUM> may be connected to the mouthpiece <NUM>. The other end of the sleeve body <NUM> may be configured with the limitation ring <NUM>. The sleeve body <NUM> may extend through the stop ring <NUM>. The limitation ring <NUM> and the mouthpiece <NUM> may be disposed on two sides of the stop ring <NUM>, the limitation ring <NUM> and the stop ring <NUM> may be engaged for position-limiting.

In other embodiments, an end of the inner barrel <NUM> facing the mouthpiece <NUM> and located in the slide cavity <NUM> may be configured with the stop ring <NUM>, such that the end of the inner barrel <NUM> facing the mouthpiece <NUM> may stop and limit the position of the other end of the stop sleeve <NUM>.

As shown in <FIG>, in the present embodiment, a sealing member may be disposed between the slide sleeve <NUM> and the inner barrel <NUM>. The sealing member may be a seal ring or a seal rib. In this way, the slide sleeve <NUM> may be received in the slide cavity <NUM> in a drop-preventing manner. The atomization core assembly <NUM> may be connected to the slide sleeve <NUM>, such that the atomization core assembly <NUM> may be received in the slide cavity <NUM> through the slide sleeve <NUM> in a drop-preventing manner.

The stop sleeve <NUM> and the slide sleeve <NUM> may be independent of each other. The stop sleeve <NUM> may push against the slide sleeve <NUM> to slide along the slide cavity <NUM>. A position of the slide sleeve <NUM> relative to the inner barrel <NUM> may remain unchanged when the mouthpiece <NUM> and the stop sleeve <NUM> are reset.

A side wall of the inner barrel <NUM> may define a liquid inlet hole <NUM>. The slide sleeve <NUM> may be staggered with the liquid inlet hole <NUM> when the atomizer core assembly <NUM> is received in the receiving channel <NUM>, such that the e-liquid in the liquid storage cavity <NUM> may enter the atomizer core assembly <NUM> through the liquid inlet hole <NUM> to be atomized. When the slide sleeve <NUM> pushes the atomizer core assembly <NUM> to expose the end of the atomizer core assembly, an outer wall of the slide sleeve <NUM> may cover the liquid inlet hole <NUM> to prevent the e-liquid in the liquid storage cavity <NUM> from leaking into the slide cavity <NUM>. Therefore, the e-liquid in the liquid storage cavity <NUM> may not leak even when the atomizer core assembly <NUM> is detached from the receiving channel <NUM>. The outer wall of the slide sleeve <NUM> maintains covering the liquid inlet hole <NUM> while the mouthpiece <NUM> and stop sleeve <NUM> are reset.

In some embodiments, the slide sleeve <NUM> may be connected to the stop sleeve <NUM>. That is, the slide sleeve <NUM> moves as the stop sleeve <NUM> moves. The atomization core assembly <NUM> may be connected to the slide sleeve <NUM>, thus the atomization core assembly <NUM> may be received in the slide cavity <NUM> in a relatively drop-preventing manner. Alternatively, the slide sleeve <NUM> and the stop sleeve <NUM> may be configured as an integrated connective structure, which is not limited by the present disclosure.

As shown in <FIG>, in the present embodiment, a protrusion <NUM> may be configured at an inner wall of an end of the slide cavity <NUM> of the inner barrel <NUM> away from the mouthpiece assembly <NUM>. The protrusion <NUM> may be configured to resist the slide sleeve <NUM>, preventing the slide sleeve <NUM> from being released from the slide cavity <NUM> and facilitating the atomizer assembly <NUM> to separate from the slide sleeve <NUM>.

In another embodiment, as shown in <FIG>, an end of the inner barrel <NUM> may be inserted into the base <NUM>, and the base <NUM> covers the end of the inner barrel <NUM>. In this way, the base <NUM> may further be configured to resist the slide sleeve <NUM> to prevent the slide sleeve <NUM> from being released from the slide cavity <NUM> through the end of the receiving channel <NUM>. Further, the base <NUM> may provide a pushing force to the slide sleeve <NUM> to facilitate the atomizer assembly <NUM> to separate from the slide sleeve <NUM>.

As shown in <FIG> and <FIG>, in the present embodiment, the mouthpiece assembly <NUM> may further include a connection sleeve <NUM>, and the mouthpiece <NUM> and the stop sleeve <NUM> may be indirectly connected through the connection sleeve <NUM>. The connection sleeve <NUM> may include a guide sleeve body <NUM> and a connection sleeve body <NUM> sleeving the guide sleeve body <NUM>. The guide sleeve body <NUM> and the connection sleeve body <NUM> may be connected through an end plate <NUM>. The mouthpiece <NUM> and the stop sleeve <NUM> may be received in two ends of the connection sleeve body <NUM>. An end of the elastic member <NUM> may abut against the end plate <NUM>. The elastic member <NUM> may be elastically compressed between the end plate <NUM> and the stop ring <NUM>. The guide sleeve body <NUM> may be slidably guided and received in the guide cavity <NUM> to ensure that the mouthpiece assembly <NUM> slides in a straight line along the guide cavity <NUM>.

As shown in <FIG>, the connection sleeve body <NUM> may be in a shape of a straight barrel.

As shown in <FIG>, in another embodiment, the connection sleeve body <NUM> may include a first barrel section <NUM> and a second barrel section <NUM>, connected to each other. An inner diameter of the first barrel section <NUM> may be greater than an inner diameter of the second barrel section <NUM>. The mouthpiece <NUM> may be received in the first barrel section <NUM>, and the stop sleeve <NUM> may be embedded in the second barrel section <NUM>, such that a radius of the stop sleeve <NUM> may be reduced along a radial direction. Correspondingly, a radius of the slide sleeve <NUM> may be reduced along the radial direction. Further, a radius of the inner barrel <NUM> may also be reduced along the radial direction. In this way, a volume of the liquid storage cavity <NUM> may be relatively increased, such that more e-liquid may be stored in the liquid storage cavity <NUM>.

In other embodiments, the mouthpiece <NUM> and the stop sleeve <NUM> may be directly connected without the connection sleeve <NUM>, such that the elastic member <NUM> may be directly elastically compressed between the mouthpiece <NUM> and the stop ring <NUM>.

As shown in <FIG>, an end of the slide sleeve <NUM> facing the atomization core assembly <NUM> may define an insertion slot <NUM>. An end of the atomization core assembly <NUM> may be inserted in the insertion slot <NUM>. In this way, the atomization core assembly <NUM> may be assembled in a drop-preventing manner by being received in the receiving channel <NUM>. The atomization core assembly <NUM> may also be inserted to the slide sleeve <NUM> or connected to the slide sleeve <NUM> via a buckle, and the like.

Specifically, as shown in <FIG>, the end of the slide sleeve <NUM> facing the atomization core assembly <NUM> may be provided with an inner barrel wall <NUM> and an outer barrel wall <NUM>, and an axis of the inner barrel wall <NUM> may be parallel to an axis of the outer barrel wall <NUM>. The insertion slot <NUM> may be defined between the inner barrel wall <NUM> and the outer barrel wall <NUM>. An end of the atomization core assembly <NUM> may be received between the inner barrel wall <NUM> and the outer barrel wall <NUM>. The atomization core assembly <NUM> may be embedded between the inner barrel wall <NUM> and/or the outer barrel wall <NUM> with an elastic seal member, thereby enabling the atomization core assembly <NUM> to be connected to the slide sleeve <NUM>.

In other embodiments, the atomization core assembly <NUM> may be inserted into the slide sleeve <NUM> or connected to the slide sleeve <NUM> through a buckle. Alternatively, the atomization core assembly <NUM> may be threaded to the slide sleeve <NUM>. The present disclosure does not limit the connection therebetween.

As shown in <FIG>, the slide sleeve <NUM> may be in a shape of a straight barrel.

As shown in <FIG>, in another embodiment, the slide sleeve <NUM> may include a first slide sleeve section <NUM> and a second slide sleeve section <NUM>, connected to each other. An outer diameter of the first slide sleeve section <NUM> may be less than an outer diameter of the second slide sleeve section <NUM>. An end of the second slide sleeve section <NUM> away from the first slide sleeve section <NUM> may define the insertion slot <NUM>. Therefore, a radius of the slide sleeve <NUM> may be reduced gradually, such that the radius of the inner barrel <NUM> may be reduced, and the volume of the liquid storage cavity <NUM> may be increased.

As shown in <FIG> is another cross-sectional view of the atomizer shown in <FIG>. The atomizer <NUM> shown in <FIG> may be obtained by optimizing the atomizer <NUM> shown in <FIG>. <FIG> is a structural schematic view of the connection sleeve of the atomizer shown in <FIG>. <FIG> is a structural schematic view of the slide sleeve of the atomizer shown in <FIG>.

By optimizing the stop sleeve <NUM>, the connection sleeve <NUM> and the slide sleeve <NUM>, the volume of the liquid storage cavity <NUM> may be effectively increased, such that increased amount of e-liquid may be stored in the liquid storage cavity <NUM>.

As shown in <FIG> is another structural schematic view of the atomizer of the electronic atomization device shown in <FIG>. <FIG> is a structural schematic view of a stop sleeve and a slide sleeve of the atomizer shown in <FIG> configured as an integral overall structure. The atomizer <NUM> does not include the end cap assembly <NUM>, and the entire atomization core assembly <NUM> is received in the receiving channel <NUM>.

In the atomizer <NUM>, the inner barrel <NUM> may be inserted into the guide cavity <NUM> of the top cover <NUM> and may abut against an end of the guide cavity <NUM>. The mouthpiece <NUM> may be slidably received into the guide cavity <NUM> and sealed by a seal member. The elastic member <NUM> may be elastically compressed between the mouthpiece <NUM> and the inner barrel <NUM>. The stop sleeve <NUM> and the slide sleeve <NUM> may be connected integrally, that is, the stopper sleeve <NUM> and the slide sleeve <NUM> may be an integral overall structure. An end of the stop sleeve <NUM> may be inserted with the mouthpiece <NUM>.

Specifically, the inner barrel <NUM> may include a barrel body <NUM> and a ring stop portion <NUM> disposed at an end of the barrel body <NUM>. The ring stop portion <NUM> may further extend into the guide cavity <NUM>. The ring stop portion <NUM> may be sealed with the guide cavity <NUM>. The elastic member <NUM> may be elastically compressed between the mouthpiece <NUM> and the ring stop portion <NUM>. The other end of the stop sleeve <NUM> may be arranged on a side of the ring stop portion <NUM> away from the elastic member <NUM> and may be engaged with the ring stop portion <NUM> in a position-limiting manner.

By configuring the stop sleeve <NUM> and the slide sleeve <NUM> as an integral overall structure, a process of manufacturing the stop sleeve <NUM> and the slide sleeve <NUM> may be simplified, and manufacturing costs may be reduced. A process of assembling the atomizer <NUM> may be further simplified.
