Description

Technical Field

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

[0002] Aerosol generating devices are used to generate aerosols for users to inhale. Aerosol generating devices using aerosol generating liquid typically include an atomizer and a power supply component. The atomizer includes a housing, a liquid reservoir, and an atomizing component. The aerosol generating liquid enters the atomizing component from the liquid reservoir, causing the atomizing component to electrically heat the liquid, which then atomizes to generate aerosol. To replenish the liquid reservoir and extend usage time, current aerosol generating devices usually also include a replenishment container. The replenishment container is detachable from the atomizer. When replenishment is needed, the aerosol generating device is inverted or the replenishment container is squeezed, allowing the aerosol generating liquid in the container to enter the liquid reservoir, thus replenishing the liquid. However, current aerosol generating devices often suffer from the problem of liquid flowing back into the replenishment container during replenishment, resulting in poor replenishment efficiency.

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include direct connection, indirect connection, and contact connection (linkage).

[0041] In one embodiment, please refer to Figures 1 to 3 The aerosol generating device includes a liquid replenishment container 1, a power supply component 2, and an atomizer 3, wherein the power supply component 2 supplies power to the atomizer 3. In one embodiment, the liquid replenishment container 1 is a liquid replenishment bottle 10, which is detachably installed in the housing 31 of the atomizer 3.

[0042] In one embodiment, please refer to Figures 1 to 3 The atomizer 3 includes a housing 31, an atomizing component 32, and a guide structure 33. The housing 31 contains a liquid storage chamber 34 and a replenishment channel 35. The liquid storage chamber 34 stores the aerosol generating liquid. The replenishment channel 35 connects the replenishment container 1 to the liquid storage chamber 34, replenishing the liquid storage chamber 34 with the aerosol generating liquid. The atomizing component 32 communicates with the liquid storage chamber 34, allowing the aerosol generating liquid to enter the atomizing component 32. The atomizing component 32 includes a heating element 321 for atomizing the aerosol generating liquid.

[0043] The guiding structure 33 includes a guiding cylinder 331, with a liquid guiding hole 332 on its wall. The guiding cylinder 331 is at least partially movably mounted within the outer casing 31, with at least a portion of the guiding structure 33 protruding from the outer casing 31 for operator manipulation of the guiding cylinder 331. The guiding cylinder 331 has a replenishing state and a closed state during its movement. When the guiding cylinder 331 is in the replenishing state, the replenishing channel 35 is connected to the storage chamber 34 through the liquid guiding hole 332, allowing the aerosol-generating liquid in the replenishing container 1 to enter the storage chamber 34. When the guiding cylinder 331 is in the closed state, the liquid guiding hole 332 does not connect the replenishing channel 35 to the storage chamber 34, thus blocking the replenishing channel 35 and preventing the aerosol-generating liquid in the storage chamber 34 from flowing back into the replenishing container 1.

[0044] The atomizer 3 of this application uses a guide tube 331 to control the opening and closing of the replenishment channel 35. When it is necessary to replenish the aerosol generating liquid into the storage chamber 34, the guide tube 331 is moved to the replenishment state, so that the replenishment channel 35 and the storage chamber 34 are connected through the liquid guide hole 332 of the guide tube 331. In this way, the aerosol generating liquid in the replenishment container 1 can enter the storage chamber 34 through the replenishment channel 35. After replenishment is completed, the guide tube 331 is moved to the closed state, and the guide tube 331 blocks the replenishment channel 35. In this way, the aerosol generating liquid in the storage chamber 34 cannot flow back into the replenishment container 1, thus improving the replenishment effect of the storage chamber 34 and making the replenishment effect better.

[0045] Because the aerosol generating liquid is guided to the storage chamber 34 by the guide tube 331, and the inner hole of the guide tube 331 is relatively large, the aerosol generating liquid can pass through quickly, improving the replenishment speed. Since the liquid guiding hole 332 is located on the wall of the guide tube 331, the size of the liquid guiding hole 332 can be made larger as needed, resulting in higher liquid guiding efficiency.

[0046] In one embodiment, please refer to Figure 2 and Figure 3 The guide tube 331 is positioned above the replenishment container 1, and the guide tube 331 and the storage chamber 34 are arranged to the left and right. When replenishment is required, the aerosol generating device needs to be inverted so that the aerosol generating liquid in the replenishment container 1 flows into the storage chamber 34 through the replenishment channel 35.

[0047] It is understood that, unless otherwise specified, the directions described in this application, such as up, down, left, and right, are based on the state of using the aerosol generating device.

[0048] Regarding the atomizing component 32, its structure is a relatively mature existing technology. This application only provides a brief description of the structure of the atomizing component 32. Please refer to [link / reference needed]. Figure 2The atomizing component 32 includes a component housing 322 and a liquid guiding component 323. The liquid guiding component 323 is made of a porous material, such as porous absorbent cotton. The component housing 322 has a through hole communicating with the liquid storage chamber 34, through which the aerosol generating liquid can enter the liquid guiding component 323. The heating element 321 is located inside the liquid guiding component 323. The aerosol generating liquid enters the liquid guiding component 323 through the through hole, and then comes into contact with the heating element 321 and is heated and atomized to generate an aerosol. The atomizer 3 has a nozzle 302, through which the generated aerosol can be drawn.

[0049] Regarding the heating element 321, the heating element 321 can take any feasible form, such as a heating mesh (please refer to...). Figure 2 and Figure 3 (e.g., multiple heating wires connected in parallel).

[0050] In one embodiment, please refer to Figures 2 to 5 The guide cylinder 331 is rotatably mounted in the housing 31. The guide structure 33 includes a knob 333 that engages with the guide cylinder 331 to prevent rotation. The knob 333 is rotatably mounted on the housing 31. This facilitates the machining and installation of the guide cylinder 331 and the knob 333. In one embodiment, please refer to... Figure 5 The guide cylinder 331 is inserted into the knob 333 to prevent rotation. In some other embodiments, the guide cylinder 331 may be integrally formed with the knob 333. In some other embodiments, the guide cylinder 331 may be fixed to the knob 333 by means of clamping, magnetic attraction, or fasteners. In some other embodiments, the guide cylinder 331 may also be movably assembled in the housing, and its position can be changed by pressing and pulling the guide cylinder 331.

[0051] Regarding the structure of the guide tube 331, please refer to one embodiment. Figure 2 and Figure 3 The guide cylinder 331 includes a cylinder body 3311 and a cylinder cover 3312. The cylinder cover 3312 is located at one end of the cylinder body 3311, and the other end of the cylinder body 3311 is open. A knob 333 is fitted together with the cylinder cover 3312 to prevent rotation. This facilitates the rotation of the guide cylinder 331. In some other embodiments, in addition to using the knob 333 and the cylinder cover 3312, an operating handle can also be connected to the cylinder body 3311, so that the operating handle extends out of the outer casing 31, and the guide cylinder 331 can be rotated by operating the operating handle.

[0052] Specifically, in one embodiment, please refer to Figure 2 and Figure 5 The knob 333 is provided with a locking block 3331, and the cylinder cover 3312 is provided with a locking groove. The locking block 3331 engages with the locking groove to prevent the knob 333 and the cylinder cover 3312 from rotating. In one embodiment, please refer to... Figure 2 and Figure 5The cylinder cover 3312 is provided with an installation sleeve 3313, and the slot is located at the end of the installation sleeve 3313 away from the cylinder body 3311. The knob 333 has a positioning post 3332 that is inserted into the installation sleeve 3313, and the positioning post 3332 is rotatably assembled with the installation sleeve 3313.

[0053] In one embodiment, please refer to Figure 2 and Figure 4 The atomizer 3 includes a first bracket 36, which has a first bracket hole, and a mounting sleeve 3313 is inserted into the first bracket hole and seals with the first bracket hole.

[0054] In one embodiment, please refer to Figures 3 to 5 The outer casing 31 has a knob mounting hole, and the knob 333 includes an elastic buckle 3333. The knob 333 is held on the outer casing 31 by the elastic buckle 3333 to prevent the knob 333 from detaching from the outer casing 31.

[0055] In one embodiment, please refer to Figure 2 and Figure 3 The knob 333 is located at the top of the atomizer 3, and the liquid replenishment container 1 is located below the guide tube 331. The atomizing assembly 32 and the guide tube 331 are arranged at intervals to the left and right. In one embodiment, please refer to... Figure 2 and Figure 3 The housing 31 has a power supply component space 311 and a replenishment container space 312. At least a portion of the power supply component 2 is installed in the power supply component space 311, and the replenishment container 1 is installed in the replenishment container space 312. The replenishment container space 312 and the power supply component space 311 are arranged side by side. In one embodiment, please refer to... Figure 2 and Figure 3 The atomizing component 32 is located above the power supply component 2.

[0056] In one embodiment, please refer to Figure 2 and Figure 4 The cylinder body 3311 and the cylinder cover 3312 are integrally formed. In some other embodiments, the cylinder body 3311 and the cylinder cover 3312 can also be fixed together separately.

[0057] In one embodiment, please refer to Figures 3 to 5 The liquid guiding holes 332 are arranged in pairs, with the two pairs of liquid guiding holes 332 arranged coaxially. This allows both liquid guiding holes 332 to be used as holes communicating with the liquid replenishment channel 35, reducing the installation requirements of the guide cylinder 331 during assembly and making its installation easier. In some other embodiments, only one liquid guiding hole 332 may be provided as needed. Of course, the number of liquid guiding holes 332 can also be increased as needed, such as by any number more than three. In some other embodiments, when the guide cylinder 331 is in the liquid replenishment state, two or more holes can simultaneously communicate with the liquid storage chamber 34 and the liquid replenishment channel 35.

[0058] To improve sealing performance, in one embodiment, please refer to... Figures 2 to 4 The atomizer 3 includes a seal 37, which blocks the liquid guide hole 332 in the closed state. In one embodiment, the seal 37 encloses the guide tube 331. In another embodiment, the seal 37 is made of sealing silicone. In some other embodiments, the liquid guide hole 332 may not be blocked by the seal 37 when the guide tube 331 is in the closed state, but the liquid guide hole 332 is separated from the liquid storage chamber 34.

[0059] To further improve the sealing effect, in one embodiment, please refer to... Figure 4 and Figure 5 An annular protrusion 3314 is provided at the opening where the liquid guiding hole 332 contacts the seal 37. The annular protrusion 3314 can compress the seal 37, resulting in greater deformation of the seal 37 and a better sealing effect.

[0060] In one embodiment, please refer to Figure 2 and Figure 4 The sealing element 37 is a sealing base, which seals with the atomizing assembly 32. At least a portion of the sealing base forms the bottom of the liquid storage chamber 34. In this way, the sealing element 37 not only seals the guide tube 331, but also seals the atomizing assembly 32, and also seals the liquid storage chamber 34, simplifying the sealing form in the atomizer 3, reducing the number of sealing components, and improving assembly efficiency.

[0061] In one embodiment, please refer to Figure 2 and Figure 4 The atomizer 3 includes a second bracket 38 located within the housing 31, a seal 37 sandwiched between the second bracket 38 and the guide tube 331, and the guide tube 331 sandwiched between the seal 37 and the first bracket 36. This design facilitates installation and ensures that the seal 37 provides a good seal.

[0062] In one embodiment, please refer to Figure 2 and Figure 4 At the location of the liquid storage chamber 34, the first bracket 36 and the second bracket 38 clamp the sealing element 37 to form the liquid storage chamber 34. By clamping the first bracket 36 and the second bracket 38, the liquid storage chamber 34 can be sealed, and the guide cylinder 331 can be installed at the same time, resulting in a simpler structure and more stable use.

[0063] It should be noted that the liquid replenishment channel 35 can be any form through which the aerosol generating liquid passes. For example, the liquid replenishment channel 35 can be formed by a liquid replenishment tube, or it can be a liquid replenishment hole surrounded by multiple parts. For example, in one embodiment, please refer to... Figure 2 and Figure 4The space inside the guide tube 331 forms part of the replenishment channel 35, and the second bracket 38 has a second bracket hole 381, which forms part of the replenishment channel 35.

[0064] In one embodiment, please refer to Figures 2 to 4 The replenishment container 1 is a replenishment bottle 10, and a sealing gasket 39 is provided between the replenishment bottle 10 and the second bracket 38. The second bracket 38 is also provided with a replenishment bottle fixing component 301. The bottle mouth of the replenishment bottle 10 is fixed to the replenishment bottle fixing component 301 by threads, and the replenishment bottle fixing component 301 is clamped and fixed on the second bracket 38.

[0065] In one embodiment, please refer to Figure 1 and Figure 2 In order to facilitate observation of the liquid volume in the replenishment bottle 10, the outer shell 31 has an observation window 313, which allows observation of the aerosol-generating liquid in the replenishment bottle 10.

[0066] In one embodiment, please refer to Figure 2 and Figure 3 The liquid replenishment container 1 and the power supply component 2 are both located inside the housing 31 of the atomizer 3. In some other embodiments, the power supply component 2 may also be a separate power supply module, which is fixed to the atomizer 3 by snap-fit ​​or magnetic attraction.

[0067] Regarding power supply component 2, in one embodiment, please refer to... Figure 2 and Figure 3 The power supply component 2 includes a power source 21, which supplies power to the atomizer 3. In some other embodiments, the aerosol generating device may also use a dry cell battery, in which case the power supply component 2 includes a battery mounting structure for mounting the dry cell battery.
