Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol generating device technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology
[0002] Aerosol generating devices typically include a suction channel, a liquid storage chamber, and an atomizing core assembly. The liquid storage chamber contains an aerosol generating medium, and the atomizing core assembly is disposed in the liquid storage chamber to heat the aerosol generating medium to generate aerosol. The aerosol leaves the aerosol generating medium through the suction channel for the user to inhale.
[0003] In existing technologies, to ensure that the aerosol generating medium is rapidly heated by the atomizing core component to generate aerosol when the user inhales, the aerosol generating device is typically pre-filled with the aerosol generating medium in the reservoir before sale. This allows the aerosol generating medium to contact and wet the atomizing core component before inhalation. However, pre-filling the reservoir with the aerosol generating medium can cause leakage during transportation due to shaking. Furthermore, users cannot change to other flavors of the aerosol generating medium once it is pre-filled, resulting in a poor user experience. Alternatively, users may need to use / discard the pre-filled medium before changing to another flavor, leading to waste. Additionally, existing aerosol generating media require approximately 5-10 minutes after being injected into the reservoir to wet the atomizing core component, preventing immediate inhalation and further reducing the user experience.
[0004] In summary, existing aerosol generating devices suffer from problems such as easy leakage during transportation, poor user experience, and waste. Utility Model Content
[0005] The technical problem to be solved by the embodiments of this application is that existing aerosol generating devices are prone to leakage during transportation, have a poor user experience, and cause waste.
[0006] To solve the above-mentioned technical problems, the embodiments of this application adopt the following solutions:

[0012] When the base moves toward the liquid storage cavity, the buckle engages with the second buckle groove, and the accommodating space in the liquid storage cavity decreases.
[0013] Furthermore, the distance between the first snap-fit groove and the second snap-fit groove is 2mm to 5mm.
[0014] Furthermore, the buckle includes an inclined surface facing the inside of the liquid storage cavity, the inclined surface forming an obtuse angle with the outer wall of the base, and the shapes of the first buckle groove and the second buckle groove match the buckle.
[0015] Furthermore, the base has a protrusion at the end away from the liquid storage cavity. When the latch is in the second latching groove, the protrusion abuts against the end of the opening to restrict the base from moving into the liquid storage cavity; and / or,
[0016] Along the direction from the base to the liquid storage cavity, the liquid storage cavity includes a first liquid storage cavity and a second liquid storage cavity, and a step is formed between the first liquid storage cavity and the second liquid storage cavity. When the buckle is located in the second buckle groove, the end of the base facing the liquid storage cavity abuts against the step to restrict the base from moving towards the liquid storage cavity.
[0017] Furthermore, the diameter of the liquid inlet hole is 0.5 mm to 3 mm; and / or,
[0018] The liquid inlet has multiple holes.
[0019] Furthermore, the base has an installation groove at one end facing the liquid storage chamber, the atomizing core assembly passes through the installation groove, and the groove opening of the installation groove has a chamfer, which is used to guide the aerosol generating medium into the liquid inlet.

[0023] Compared with the prior art, the embodiments of this application have the following main advantages:
[0024] The storage chamber does not contain any aerosol generating medium, thus preventing leakage during transport. Users can inject different flavored aerosol generating media into the storage chamber according to their needs.

[0037] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.
[0038] To solve the above problems, please refer to... Figures 1-5 This application provides an atomizer, comprising:
[0039] The main body 100 has a liquid storage chamber 101 and an opening inside the main body 100, and the opening connects the liquid storage chamber 101 to the external environment.
[0040] The atomizing core assembly includes a housing 220 and an atomizing core 210. The atomizing core 210 is located inside the housing 220. The housing 220 is provided with a liquid inlet 221, which connects the atomizing core 210 and the liquid storage chamber 101.
[0041] The base 200 has a sealed opening and is used to move toward the liquid storage chamber 101 to compress the receiving space of the liquid storage chamber 101.
[0042] In this embodiment, in the initial state, such as Figure 1 As shown, the liquid storage chamber 101 does not store aerosol generating media, thus preventing leakage of aerosol generating media during transportation; at the same time, users can inject aerosol generating media of different flavors into the liquid storage chamber 101 according to their own needs.
[0043] When the user is ready to aspirate the aerosol, they can first inject the aerosol generating medium into the storage chamber 101, and then move the base 200 toward the storage chamber 101 (Z direction in the figure). At this time, as... Figure 2 As shown, because the base 200 has a sealed opening, the space within the liquid storage chamber 101 decreases as the base 200 moves toward the liquid storage chamber 101. The aerosol generating medium within the liquid storage chamber 101 is then rapidly squeezed into the housing 220, allowing it to quickly wet the atomizing core assembly. The atomizing core 210 then heats the aerosol, rapidly producing aerosol. Compared to the aerosol generating medium wetting the atomizing core assembly through its own flow rate, this embodiment allows for easier manual control by the user to quickly promote the wetting of the atomizing core assembly, thus facilitating immediate aerosol inhalation.
[0044] In summary, the atomizer in this embodiment can prevent leakage during transportation, facilitate users to change different flavored aerosol generating media, and allow the aerosol generating media to quickly wet the atomizing core assembly, thereby improving the user experience.
[0045] It should be understood that the atomizer may also include a mouthpiece 103 and a suction channel 102. The suction channel 102 passes through the mouthpiece 103 and connects the atomizing core 210 with the external environment. The user can draw aerosol through the mouthpiece 103. At this time, the suction channel 102 and the liquid storage chamber 101 are indirectly connected through the liquid inlet 221. Therefore, after the space of the liquid storage chamber 101 is reduced, the liquid inlet 221 will guide the aerosol generating medium into the housing 220 to contact the atomizing core 210. The atomizing core assembly can be a single porous ceramic element, or a combination of an atomizing core 210 and a reservoir cotton 230. When the atomizing core assembly includes an atomizing core 210 and a reservoir cotton 230, the reservoir cotton 230 is disposed within the housing 220, and the suction channel 102 connects to the reservoir cotton 230. The reservoir cotton 230 is used to absorb liquid that quickly enters the housing 220 to prevent liquid from settling and accumulating at the bottom, and also assists the atomizing core 210 in achieving a uniform heating effect. In this case, the aerosol generating medium wetting the atomizing core assembly should be understood as follows: under the pressure of the reduced capacity of the reservoir cavity 101, the aerosol generating medium is quickly absorbed by the reservoir cotton 230 to achieve the function of wetting the reservoir cotton 230, and then the atomizing core 210, which is in contact with the reservoir cotton 230, heats the aerosol generating medium. In this case, the atomizing core 210 can be a heating wire or a porous ceramic element. When the atomizing core component is a single porous ceramic, the aerosol generating medium wetting the atomizing core component should be understood as the aerosol generating medium rapidly entering the pores of the porous ceramic and rapidly spreading to the surface of the porous ceramic, so as to be heated by the porous ceramic to generate aerosol.
[0046] Further, refer to Figures 2-4 Along the moving direction of the base 200, the inner wall of the liquid storage chamber 101 is provided with a first latching groove 106 and a second latching groove 107 in sequence, and the outer wall of the base 200 is provided with a latch 201, which is engaged with the first latching groove 106.
[0047] When the base 200 moves toward the liquid storage chamber 101, the buckle 201 engages with the second buckle groove 107, and the space inside the liquid storage chamber 101 decreases.
[0048] In this embodiment, the buckle 201 is engaged with the first buckle slot 106, at which time... Figure 2 As shown, the space inside the liquid storage chamber 101 is relatively large. The engagement between the first latching groove 106 and the latch 201 can prevent the base 200 from being accidentally touched and moving into the liquid storage chamber 101, thereby improving the stability of the atomizer during transportation.
[0049] When the user drives the base 200 to move into the liquid storage chamber 101, as Figure 3As shown, the latch 201 moves from the first latch groove 106 to the second latch groove 107. At this time, the second latch groove 107 is used to restrict the movement of the base 200, thereby preventing the aerosol generation medium from leaking through the gap between the base 200 and the liquid storage chamber 101 due to excessive changes in the space within the liquid storage chamber 101 in a short period of time. At the same time, the second latch groove 107 can also provide the user with a tactile feedback when driving the base 200, so that they know whether the atomizing core component has been successfully moistened.
[0050] It should be understood that multiple latches 201 can be provided. In this case, a third latch slot, a fourth latch slot, etc., can also be provided to ensure that after the base 200 moves toward the liquid storage chamber 101, multiple latches 201 can jump from one slot to another. For example, when there are two latches 201, a first latch slot 106, a second latch slot 107, and a third latch slot can be provided in sequence, and in the initial state, the two latches 201 are located in the first latch slot 106 and the second latch slot 107, respectively. When the buckle 201 is elastic, the number of slots can be equal to the number of buckles 201. For example, two buckles 201 and a first buckle slot 106 and a second buckle slot 107 are provided. In the initial state, the two buckles 201 are located in the first buckle slot 106 and the second buckle slot 107 respectively. When the base 200 moves toward the liquid storage cavity 101, one of the buckles 201 deforms to press against the inner wall of the liquid storage cavity 101, and the other buckle 201 moves from the first buckle slot 106 to the second buckle slot 107.
[0051] Further, please refer to Figures 2-4 The distance between the first buckle groove 106 and the second buckle groove 107 is 2mm to 5mm.
[0052] In this embodiment, the distance along the moving direction of the base 200 is the distance marked A in the figure. This distance design ensures precise control of the moving stroke of the base 200, avoids excessive compression that could cause deformation of the liquid storage chamber 101 or damage to the atomizing core assembly, and also ensures that the atomizing core 210 can be fully wetted by the atomizing medium after the base 200 is moved when the liquid storage chamber 101 is filled with the aerosol generating medium.
[0053] Further, please refer to Figure 4 The buckle 201 includes an inclined surface facing the inside of the liquid storage cavity 101, and the inclined surface forms an obtuse angle with the outer wall of the base 200. The shapes of the first buckle groove 106 and the second buckle groove 107 match the buckle 201.
[0054] In this embodiment, the obtuse angle is shown as angle B in the figure. The inclined surface facilitates the insertion of the base 200 into the opening, preventing the buckle 201 from breaking due to rigid contact with the bottom of the opening. At the same time, it also facilitates the buckle 201 from disengaging from the first buckle groove 106, thereby reducing the difficulty of use for the user.
[0055] Further, please refer to Figure 2 and Figure 3 The base 200 has a protrusion 202 at the end away from the liquid storage cavity 101. When the latch 201 is located in the second latch groove 107, the protrusion 202 abuts against the end of the opening to restrict the base 200 from moving toward the liquid storage cavity 101.
[0056] In this embodiment, the protrusion 202 can be used to limit the extent to which the base 200 enters the liquid storage chamber 101, so as to avoid excessive compression of the space inside the liquid storage chamber 101 in a short period of time and leakage; at the same time, the protrusion 202 can also change the angle of the gap formed between the base 200 and the main body 100, thereby preventing liquid leakage.
[0057] Furthermore, along the direction from the base 200 to the liquid storage chamber 101, the liquid storage chamber 101 includes a first liquid storage chamber and a second liquid storage chamber, and a step 104 is formed between the first liquid storage chamber and the second liquid storage chamber. When the latch 201 is located in the second latch groove 107, one end of the base 200 facing the liquid storage chamber 101 abuts against the step 104 to restrict the movement of the base 200 toward the liquid storage chamber 101.
[0058] In this embodiment, the step 104 is located on the inner wall of the liquid storage cavity 101 and can abut against the surface of the base 200 facing the inside of the liquid storage cavity 101, thereby limiting the extent to which the base 200 enters the liquid storage cavity 101 and preventing excessive compression of the space inside the liquid storage cavity 101 in a short period of time, which would cause leakage. At the same time, the step 104 can also change the angle of the gap formed between the base 200 and the inner wall of the liquid storage cavity, thereby preventing liquid leakage.
[0059] It should be understood that the protrusion 202 is an annular protrusion 202, and the step 104 can be an annular step 104, so as to reduce the contact area between the base 200 and the main body 100, thereby avoiding damage caused by excessive local stress on both.
[0060] Further, please refer to Figures 1-5 The diameter of the liquid inlet hole 221 is 0.5mm to 3mm.
[0061] In this embodiment, the lower limit of the aperture range of the liquid inlet 221 allows for a suitable flow rate of the aerosol generating medium entering the housing 220, avoiding excessively low flow rates that could affect the user experience; the upper limit prevents excessive aerosol generating medium from instantly entering the atomizing core assembly, thus avoiding leakage. Furthermore, the liquid inlet 221 has multiple apertures.
[0062] In this embodiment, when there are multiple liquid inlet holes 221, they can contact the atomizing core 210 from multiple angles to make full use of the atomizing core 210 to complete the heating, thereby improving the heating efficiency of the aerosol generating medium.
[0063] Further, please refer to Figure 4 and Figure 5 The base 200 has an installation groove at one end facing the liquid storage chamber 101. The atomizing core assembly passes through the installation groove. The groove opening is provided with a chamfer 204, which is used to guide the aerosol generating medium into the liquid inlet 221.
[0064] In this embodiment, the chamfer 204 can guide the aerosol generating medium into the housing 220 to improve the wetting speed of the atomizing core 210; at the same time, when the residual amount of aerosol generating medium is small, it can guide the aerosol generating medium located on the base 200 to flow into the liquid inlet hole 221 along the chamfer 204.
[0065] Further, please refer to Figure 4 and Figure 5 The base 200 is provided with a mounting surface 203, and a mounting groove is provided on the mounting surface 203. Along the direction from the base 200 to the liquid storage chamber 101, the mounting surface 203 is perpendicular to the liquid inlet hole 221, and the bottom of the liquid inlet hole 221 is aligned with the bottom of the chamfer 204.
[0066] In this embodiment, the fact that the mounting surface 203 is perpendicular to the liquid inlet hole 221 should be understood as meaning that, along the Z direction in the figure, the distance from the upper and lower ends of the mounting surface 203 to the liquid inlet hole 221 is the same. At this time, the gap range between the chamfer 204 and the housing 220 is appropriate, which can avoid the gap being too large and some aerosol generating medium remaining in the gap, while also allowing the chamfer 204 to fully guide the aerosol generating medium through the liquid inlet hole 221.
[0067] Further, please refer to Figures 1-3 The main body 100 is provided with an injection hole 105 and a plug 300. The plug 300 plugs the injection hole 105 and is detachably connected to the injection hole 105.
[0068] In this embodiment, the injection hole 105 allows the user to easily add aerosol generating medium into the liquid storage chamber 101, and the blocking component 300 can be disassembled or connected to the injection hole 105 to control the opening and blocking of the injection hole 105.
[0069] Further, please refer to Figures 1-5 The base 200 is provided with a handle groove (not shown in the figure) at the end away from the liquid storage cavity 101. The handle groove is a single-sided narrow groove that allows the user to insert their fingers into the handle groove and abut against the inner top wall of the handle groove to separate the base 200 from the main body 100, thereby realizing the reset of the base 200.
[0070] Accordingly, please refer to Figures 1-5This application also provides an aerosol generating device, which includes a main unit and an atomizer according to any of the above embodiments. The main unit is electrically connected to the atomizing core assembly in the atomizer and is used to provide electrical energy to the atomizing core.
[0071] In this embodiment, since the aerosol generating medium includes any of the atomizers in the above embodiments, the liquid storage chamber 101 does not store any aerosol generating medium. Therefore, leakage of the aerosol generating medium during transportation can be avoided. Simultaneously, users can inject different flavored aerosol generating media into the liquid storage chamber 101 according to their needs. Furthermore, by moving the drive base 200 towards the liquid storage chamber 101, the space within the liquid storage chamber 101 can be compressed, allowing the aerosol generating medium to quickly pass through the inlet hole 221 and saturate the atomizing core assembly. It is then heated by the atomizing core 210 to rapidly generate aerosol. The main unit can be equipped with a battery or other power supply components, enabling the main unit to be electrically connected to the atomizing core via the battery, thereby providing power to the atomizing core 210, allowing the atomizing core 210 to heat the aerosol generating medium.
