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.

[0040] 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.

[0041] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections.

[0042] Reference Figures 1 to 12 As shown in the figure, this application provides an atomizer for heating an aerosol generation matrix to form an aerosol.

[0043] In some embodiments, refer to Figure 1 and Figure 2 As shown, the atomizer includes a housing 1, a mouthpiece 3, and a first seal 4; further refer to Figure 3 and Figure 4 As shown, an oil reservoir 2 is formed inside the housing 1. An oil injection hole 121 is provided at the first end 12 of the first end of the housing 1. The oil reservoir 2 is connected to the oil injection hole 121. A first sealing member 4 is provided inside the housing 1. The first sealing member 4 is located between the oil reservoir 2 and the first end 12. The first sealing member 4 has an open state that allows the oil injection device to be inserted into the oil reservoir 2, and a closed state that returns from the open state. In the closed state, the first sealing member 4 seals the oil reservoir 2. A suction nozzle 3 is displaceably connected to the first end of the housing 1. In the displaced state, the first sealing member 4 and the oil injection hole 121 are exposed.

[0044] In this embodiment, the housing 1 protects the first seal 4 located within the housing 1 and forms the oil reservoir 2. The mouthpiece 3 is repositionably connected to the first end of the housing 1. The mouthpiece 3 has a repositioned state and a connected state. In the repositioned state, one scenario is that the mouthpiece 3 moves away from the housing 1, exposing the first seal 4 and the oil filling hole 121. In this case, the mouthpiece 3 and the housing 1 are separated, and the atomizer is divided into two parts: a separate mouthpiece 3 and a separate housing 1 (the oil reservoir 2 and the first seal 4 are both located inside the housing 1). This reduces the number of atomizer components, avoiding poor appearance quality and component loss caused by a large number of components. Another scenario is that the mouthpiece 3 and the housing 1 remain connected. The mouthpiece 3 and the housing 1 are exposed by translation or rotation. In the connected state, the mouthpiece 3 is connected to the housing 1 and can be used by the user, while the first seal 4 and the oil filling hole 121 are hidden.

[0045] In the displaced state, the first seal 4 and the oil filling hole 121 are exposed. Since the first seal 4 closes the oil filling hole 121, the aerosol generating matrix in the oil tank 2 will not flow out, thus avoiding leakage of the aerosol generating matrix from the oil filling hole 121 after it is exposed, which would affect user satisfaction. Moreover, the nozzle 3 is directly exposed at the oil filling hole 121 in the displaced state, without the need to disassemble other components, making it more convenient for users to replenish the aerosol generating matrix into the oil tank 2 through the oil filling hole 121. When it is necessary to inject the aerosol generating matrix into the oil tank 2, the oil bottle's nozzle can easily push open the first seal 4 and insert into the oil tank 2, realizing the injection of the aerosol generating matrix into the oil tank 2 through the oil filling hole 121; after the oil bottle's nozzle is pulled out of the oil filling hole 121, the first seal 4 returns from the open state to the closed state, and the first seal 4 closes the oil filling hole 121 again.

[0046] The atomizer of this embodiment includes a first sealing element 4 located within the housing 1, between the oil reservoir 2 and the first end 12. When open, the first sealing element 4 allows the filling device to be inserted into the oil reservoir 2, enabling the injection of the aerosol generation matrix into the oil reservoir 2 and ensuring normal replenishment of the aerosol generation matrix within the atomizer. When closed, the first sealing element 4 seals the oil reservoir 2, preventing leakage of the aerosol generation matrix even if the filling hole 121 is exposed. This is particularly effective in preventing leakage if a child accidentally disassembles the mouthpiece 3 from the housing 1, thus improving user satisfaction.

[0047] In some possible implementations, refer to Figure 5 As shown, the first sealing member 4 is provided with a sealing part 41, and the thickness of the sealing part 41 in the Z direction is in the range of 0.3mm-0.8mm. When the thickness of the sealing part 41 is within the above range, the sealing part 41 is relatively thin, which can better seal the oil tank 2 while allowing the oil injection equipment to be inserted into the oil tank 2 under external force.

[0048] It is understood that the thickness of the sealing part 41 can be set according to the usage requirements. For example, the thickness of the sealing part 41 in the Z direction is one of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, or any value between the above values.

[0049] Reference Figure 5 and Figure 6 As shown, the first sealing element 4 is a circular plate structure, and the thickness of the sealing part 41 is less than the rest of the first sealing element 4. The sealing part 41 is provided corresponding to the oil injection hole 121.

[0050] In this embodiment, the thickness of the sealing part 41 is less than the rest of the first sealing member 4, so the sealing part 41 is relatively thin. Thus, the sealing part 41 can deform under force to open the oil injection hole 121, ensuring that aerosol matrix can be injected into the oil tank 2.

[0051] In some possible implementations, refer to Figure 6 As shown, the surface of the first sealing member 4 facing the oil tank 2 has a first groove 42. The first groove 42 is located at the edge of the first sealing member 4, and the bottom of the first sealing member 4 at the groove 42 forms a sealing part 41. Thus, the method and structure of forming the sealing part 41 are relatively simple. When it is necessary to inject aerosol into the oil tank 2 to generate a matrix, the oil bottle's nozzle pushes open the sealing part 41, and the sealing part 41 deforms into the first groove 42. The first groove 42 provides space for the deformation of the sealing part 41 and avoids the sealing part 41 from extending into the oil tank or extending too much into it and interfering with the components inside the oil tank 2, thus affecting the normal use of the components inside the oil tank 2.

[0052] Reference Figure 5 and Figure 6 As shown, the surface of the first seal 4 facing the first end 12 of the housing 1 is a complete surface.

[0053] In some possible implementations, refer to Figure 6 As shown, around the circumference of the first seal 4, the first groove 42 has two opposing groove walls 421; the distance between the two opposing groove walls 421 decreases from the outer periphery of the first seal 4 toward the center of the first seal 4.

[0054] In this embodiment, around the circumference of the first seal 4, the portion of the sealing part 41 near the middle of the first seal 4 is smaller than the portion of the sealing part 41 located at the edge of the first seal 4. This smaller portion near the middle of the first seal 4 provides better support for the sealing part 41, allowing it to seal the oil filling hole 121 in its natural state. When the oil bottle's nozzle pushes open the sealing part 41, the portion of the sealing part 41 located at the edge of the first seal 4 is more prone to deformation, allowing the nozzle to insert into the oil tank 2 and inject aerosol to form a matrix. Therefore, the change in distance between the two opposing groove walls 421 in this embodiment allows the sealing part 41 to effectively and elastically seal the oil filling hole 121.

[0055] In some other possible implementations, refer to Figure 7 As shown, the occlusion portion 41 includes at least two valves 43, one end of which is connected to the edge of the occlusion portion 41, and the other end of which extends into the center of the occlusion portion 41. Wherein, Figure 7In the diagram, the dashed line indicates the edge of the sealing part 41. This dashed line is only used to illustrate the edge of the sealing part 41 and does not limit the specific shape of the edge of the sealing part 41. For example, in... Figure 7 In the middle, the edge of the sealing part 41 is fan-shaped. Of course, the edge of the sealing part 41 can also be a circle, an ellipse, a square or other polygon, as long as it meets the usage requirements.

[0056] At least two valves 43 are located on the same plane and form a movable sealing portion 41 that closes the oil injection hole 121. The shapes of the at least two valves 43 may be the same or different. There may be two, three, or more valves 43. The edge shape of the sealing portion 41 is adapted to the shape of the oil injection hole 121. For example, when the oil injection hole 121 is circular, the shapes of the at least two valves 43 may be fan-shaped or semi-circular, and the fan-shaped valves 43 or semi-circular valves 43 form a circular sealing portion 41; when the oil injection hole 121 is square, the shapes of the at least two valves 43 may be square and / or triangular to form a square sealing portion 41. In this way, when the valves 43 are not pushed open, the sealing portion 41 can prevent the aerosol generation matrix from flowing out of the oil injection hole 121, so that when the nozzle 3 is separated from the housing 1 and the housing 1 is tilted, it is difficult for the aerosol generation matrix to flow out of the oil injection hole 121. In this way, when children or users misunderstand the locking nozzle 3, it can effectively prevent the aerosol generation matrix from leaking out of the oil filling hole 121 and affecting user satisfaction.

[0057] In some possible implementations, refer to Figure 4 , Figure 5 and Figure 8 As shown, the first sealing element 4 has a first through hole 44; the housing 1 has an air outlet 122 and a housing air guide 11. The air outlet 122 is located at the first end 12, and the housing air guide 11 extends from the first end 12 into the oil tank 2, passing through the first through hole 44. The housing air guide 11 has a first air passage 17 inside; the suction nozzle 3 has a second air passage 31, and the first air passage 17, the air outlet 122, and the second air passage 31 are sequentially connected. In this way, the aerosol formed by the aerosol generation matrix in the oil tank 2 can flow out sequentially through the first air passage 17, the air outlet 122, and the second air passage 31.

[0058] In this embodiment, the air guide portion 11 of the housing passes through the first through hole 44 of the first seal 4, so the first seal 4 will not block the output of aerosol, and the aerosol in the atomizer can flow out smoothly.

[0059] In some possible implementations, in order to achieve the installation of the first seal 4 and ensure that the first seal 4 does not move in its natural state or when pushed down by the oil bottle's nozzle, refer to Figure 4 and Figure 5As shown, the first sealing element 4 is provided with a positioning hole 45, and the first end 12 of the housing 1 is provided with a positioning post 13, which is inserted into the positioning hole 45.

[0060] In some possible implementations, refer to Figure 4 and Figure 10 As shown, the atomizer also includes a second seal 5, further referencing Figure 11 As shown, the suction nozzle 3 is provided with a receiving cavity 32, and the second sealing member 5 is assembled in the receiving cavity 32. When the suction nozzle 3 is connected to the first end of the housing 1, the second sealing member 5 seals the oil injection hole 121.

[0061] In the atomizer of this application embodiment, in the connected state, the second sealing member 5 covers the oil filling hole 121. At this time, the first sealing member 4 covers the side of the oil filling hole 121 facing the oil tank 2, and the second sealing member 5 covers the side of the oil filling hole 121 facing the mouthpiece 3. That is, the first sealing member 4 and the second sealing member 5 jointly cover the oil filling hole 121, effectively preventing the aerosol generation matrix from leaking out of the oil filling hole 121, thereby improving user satisfaction.

[0062] In some possible implementations, refer to Figure 4 , Figure 10 , Figure 11 , Figure 12 As shown, the nozzle 3 also has a nozzle air guide 33, which extends from the end of the nozzle 3 away from the housing 1 into the accommodating cavity 32. A second air passage 31 is formed within the nozzle air guide 33. A second through hole 51 is provided in the middle of the second sealing member 5. The first end of the housing 1 is inserted into the accommodating cavity 32. A portion of the second sealing member 5 is located between the nozzle air guide 33 and the first end 12. The air outlet 122, the second through hole 51, and the second air passage 31 of the housing 1 are sequentially connected. In this way, the second sealing member 5 can seal the gap between the air outlet 122 of the housing 1 and the second air passage 31 of the nozzle 3 while sealing the oil filling hole 121, thus preventing aerosol leakage.

[0063] In some possible implementations, the atomizing device is radial, as referenced. Figure 8 As shown, the first end of the housing 1 is provided with a contraction portion 14 that tapers radially inward towards the inside of the housing 1, and the end of the contraction portion 14 is the first end portion 12. The sidewall of the contraction portion 14 is provided with a second annular groove 143 and a locking protrusion 141. The second annular groove 143 is recessed radially inward from the sidewall of the contraction portion 14 towards the inside of the housing 1, and the locking protrusion 141 protrudes radially away from the sidewall of the contraction portion 14 towards the direction away from the housing 1. The first end portion 12 is provided with a first locking protrusion 142 corresponding to the position of the second annular groove 143. The sidewall of the first locking protrusion 142 is flush with the sidewall of the contraction portion 14, and the first locking protrusion 142 extends circumferentially from the first end portion 12 towards the second annular groove 143. The radial direction can be referenced... Figure 8 The direction indicated by the middle arrow X.

[0064] Reference Figure 11 As shown, the cavity wall of the receiving cavity 32 of the suction nozzle 3 is provided with a second snap-fit ​​protrusion 36, a first annular groove 34 and a locking groove 35. The first annular groove 34 and the locking groove 35 are arranged adjacent to each other. The curvature of the first annular groove 34 is greater than the curvature of the locking groove 35. The shape of the locking groove 35 is adapted to the shape of the snap-fit ​​protrusion 141.

[0065] During the connection process between the nozzle 3 and the housing 1, the second locking protrusion 36 moves axially toward the housing 1, and the second locking protrusion 36 passes through the position where the first locking protrusion 142 is not provided and inserts into the second annular groove 143. The locking protrusion 141 is inserted into the first annular groove 34. When the nozzle 3 and the housing 1 are rotated relative to each other, when the second locking protrusion 36 rotates to the second annular groove 143 below the first locking protrusion 142, the first locking protrusion 142 prevents the second locking protrusion 36 from disengaging axially. At the same time, the locking protrusion 141 moves out of the first annular groove 34 and into the locking groove 35. The cooperation between the locking protrusion 141 and the locking groove 35 can prevent the nozzle 3 and the housing 1 from rotating relative to each other. In this way, a reliable connection between the nozzle 3 and the housing 1 can be achieved.

[0066] During the disassembly of the nozzle 3 and the housing 1, the nozzle 3 and the housing 1 are rotated in opposite directions. When the second locking protrusion 36 rotates to the second annular groove 143 where the first locking protrusion 142 is not located, the locking protrusion 141 moves out of the locking groove 35 and into the first annular groove 34. Since there is no obstruction from the first locking protrusion 142, the nozzle 3 can be moved away from the housing 1 along the axial direction of the atomizer, thus separating the nozzle 3 and the housing 1. The axial direction can be referenced... Figure 8 The direction indicated by the middle arrow Z.

[0067] The connection and disassembly process of the nozzle 3 and the housing 1 in this embodiment is simple and convenient, and has the advantage of reliable connection.

[0068] In some possible implementations, refer to Figure 2 As shown, the atomizer also includes an atomizing component 6, a third seal 71, a fourth seal 72, a bracket 73, oil-absorbing cotton 74, and a sealing ring 76.

[0069] Further reference Figure 4 and Figure 10As shown, the atomizing component 6, the third seal 71, the fourth seal 72, the bracket 73, the oil-absorbing cotton 74, and the sealing ring 76 are respectively disposed inside the housing 1. One end of the atomizing component 6 is inserted into the oil tank 2, and the other end of the atomizing component 6 is connected to the air guide part 11 of the housing. A third seal 71 is provided at the connection point. A third through hole 711 is provided in the middle of the third seal 71. The third through hole 711 connects the first air passage 17 and the atomizing component 6, so that the generated aerosol can flow out from the atomizing component 6 through the third through hole 711, the first air passage 17, the air outlet 122, the second through hole 51, and the second air passage 31 from the mouthpiece outlet 37 of the mouthpiece 3. A mouthpiece plug 75 can also be provided to block the mouthpiece outlet 37 when the atomizer is not in use.

[0070] The atomizing component 6 is connected to an external power supply component via a conductive sheet 61 and a connecting piece 62. The conductive sheet 61 is disposed inside the housing, and the connecting piece 62 is connected to the conductive sheet 61. The connecting piece 62 is located at the bottom of the housing 1. (Refer to...) Figure 13 As shown, the connecting piece 62 is exposed at the bottom of the housing 1.

[0071] The fourth seal 72 is located at the end of the oil tank 2 opposite to the first seal 4. The fourth seal 72 has a fourth through hole 721, through which the atomizing component 6 is inserted into the oil tank 2. In this embodiment, the first seal 4, the fourth seal 72, and the side wall of the shell together enclose the oil tank 2. The first seal 4 and the fourth seal 72 are used to prevent leakage of the aerosol generation matrix in the oil tank 2.

[0072] The bracket 73 is located on the side of the fourth seal 72 away from the oil tank 2. The bracket 73 is mainly used for support, such as supporting the fourth seal 72, so that the components inside the housing are stably installed.

[0073] Oil-absorbing cotton 74 is placed between the support 73 and the bottom of the housing 1. Oil-absorbing cotton 74 is used to absorb the condensed aerosol and prevent aerosol leakage from affecting user satisfaction.

[0074] In this embodiment, the housing 1 includes a first housing 15 and a second housing 16. One end of the first housing 15 is provided with a first end cap 12, and the other end is connected to the second housing 16. A sealing ring 76 is provided at the connection between the first housing 15 and the second housing 16. The housing 1 is configured as separate units through the first housing 15 and the second housing 16 to facilitate and realize the assembly of the internal components of the housing 1.

[0075] In some embodiments, an atomizing device is provided, which includes an atomizer as described above and a power supply component connected to the atomizer. Since the aerosol generation matrix will not leak from the atomizer hole 121 after the mouthpiece 3 is exposed in the displaced state, the leakage of the aerosol generation matrix caused by accidentally opening the mouthpiece 3 is avoided. Thus, the user's satisfaction with the atomizing device can be effectively improved.

[0076] The power supply unit provides electrical energy to the atomizer, which heats the atomizing medium into an aerosol. This atomizing device can be a disposable or refillable product. For disposable atomizing devices, the atomizer and power supply unit are fixedly connected; for refillable atomizing devices, the atomizer (refer to [reference needed])... Figure 4 The atomizer (as shown) is detachably connected to the power supply assembly, and the atomizer and power supply assembly can be replaced depending on the usage. The above-described atomizing device is only one embodiment of this application; other atomizing devices with atomizers are also within the protection scope of this application. The specific internal structure of the atomizing device will not be described in detail.

[0077] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
