Description

Technical Field

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

[0002] An aerosol device generally consists of a main body and an aerosol cartridge. The aerosol cartridge contains an aerosol matrix, and the main body is used to form the aerosol matrix within the cartridge into an aerosol for the user to inhale. The main body typically has an air inlet that connects to an internal air passage to balance the air pressure inside and outside the air passage, allowing the aerosol formed within the air passage to flow to the outside of the aerosol device.

[0003] For aerosol inhalation devices, generally speaking, the larger the cross-sectional area of ​​the air inlet, the greater the inhalation resistance (hereinafter referred to as resistance). Different levels of resistance can provide users with different inhalation experiences. Currently, in order to experience different levels of resistance at any time, users have to carry multiple aerosol devices with different resistance levels, which is inconvenient. Utility Model Content

[0004] In view of this, this application provides an aerosol device body and an aerosol device, which can adjust the suction resistance level as needed and is easy to carry.

[0005] An embodiment of this application provides an aerosol device body, including a housing, an air passage inside the housing, and an air inlet in the housing, which communicates with the air passage. The aerosol device body also includes an air inlet switching component, which covers the air inlet and is rotatably connected to the housing. The air inlet switching component has at least a first adjustment hole and a second adjustment hole, with the cross-sectional area of ​​the first adjustment hole being larger than that of the second adjustment hole. When the air inlet switching component is rotated, the first adjustment hole and the second adjustment hole can communicate with the air inlet in sequence, so that the air inlet is connected to the outside of the housing.

[0006] In use, the main body of this aerosol device can be rotated to connect the first or second adjustment hole with the air inlet by rotating the air inlet switch as needed. Since the cross-sectional area of ​​the first adjustment hole is larger than that of the second adjustment hole, aerosol devices using this main body can have different levels of suction resistance. Therefore, by carrying only one aerosol device using this main body, one can experience different levels of suction resistance; carrying a single aerosol device using this main body is more convenient than carrying two or more aerosol devices.

[0007] In some embodiments of this application, along the rotation direction of the intake switching member, the intake switching member is adapted to adjust the overlap area between the first adjustment hole and the intake hole by rotation.

[0008] When the air intake switching component is rotated, the overlapping area between the first adjustment hole and the air intake hole can be adjusted to adjust the opening of the air intake hole, thereby adjusting the resistance of the gas flowing into the air intake hole, and thus achieving the effect of adjusting the suction resistance of the aerosol device body.

[0009] In some embodiments of this application, the first adjustment hole is provided through the axial direction of the intake switching component, and the first adjustment hole extends along the rotation direction of the intake switching component and is strip-shaped.

[0010] As the intake switching component rotates from a non-overlapping state to an overlapping state between the first adjusting hole and the intake hole, looking along the axial direction of the intake switching component's rotation axis towards the first adjusting hole, the overlapping area of ​​the first adjusting hole and the intake hole gradually increases. This causes the opening of the intake hole to gradually increase, thereby gradually reducing the resistance to gas flow into the intake hole, thus achieving the effect of adjusting the suction resistance. After the overlapping area of ​​the first adjusting hole and the intake hole reaches its maximum, and the intake switching component continues to rotate, the overlapping area of ​​the first adjusting hole and the intake hole gradually decreases. By aligning the strip-shaped first adjusting hole with the intake hole, the opening of the intake hole can be steplessly adjusted by the first adjusting hole, with a large adjustment range.

[0011] In some embodiments of this application, a plurality of second adjustment holes are arranged sequentially at intervals along the rotation direction of the air intake switching component. When the air intake switching component is rotated, one or more of the plurality of second adjustment holes can communicate with the air intake hole.

[0012] When the intake switching component is rotated, one or more of the several second adjusting holes can communicate with the intake hole. The intake volume of the intake hole can be adjusted by connecting several second adjusting holes of different diameters or different numbers of second adjusting holes with the intake hole. By connecting different or different numbers of second adjusting holes with the intake hole, the adjustment accuracy of the opening of the intake hole by the second adjusting holes is high.

[0013] In some embodiments of this application, the intake switching component is provided with a closed area. When the intake switching component is rotated, the closed area can move to the intake port and seal the intake port.

[0014] When the intake switching component is rotated, the sealing area can move to the intake port and seal the intake port, thereby sealing the air passage and keeping the air passage clean.

[0015] In some embodiments of this application, one of the housing and the air intake switching component is provided with an elastic protrusion, and the other of the housing and the air intake switching component is provided with a plurality of limiting grooves. The plurality of limiting grooves are arranged sequentially at intervals along the rotation direction of the air intake switching component. When the air intake switching component is rotated, the elastic protrusion can be aligned with all the limiting grooves in sequence and inserted into the corresponding limiting groove.

[0016] When the elastic protrusion is outside the limiting groove, the elastic protrusion undergoes elastic deformation. When the elastic protrusion is aligned with the limiting groove, the deformation of the elastic protrusion is restored, allowing the elastic protrusion to insert into the corresponding clearance groove, thereby limiting the rotation of the intake switching component relative to the housing. This improves the stability of the intake switching component after it has rotated to the predetermined position.

[0017] In some embodiments of this application, the outer casing is provided with a mounting hole, the air intake switching component is provided with a rotating sleeve, the rotating sleeve is rotatably disposed in the mounting hole, the aerosol device body also includes a circuit board and a button, the circuit board is provided with a button element, the button element is disposed facing the mounting hole, the button is inserted into the rotating sleeve and can slide along the axial direction of the rotating sleeve to press the button element.

[0018] The button element can be configured to adjust power or switch the display screen on / off, etc. Pressing the button element triggers the corresponding power adjustment or display screen switching function. By placing the button on the air intake switching component, the functionality of this aerosol device can be further enriched.

[0019] In some embodiments of this application, the button includes a pressing part, a contact part, and an abutting part. The contact part and the abutting part are both connected to the pressing part. The contact part is configured to abut against the button element. A stop part is provided on the rotating sleeve. The stop part is configured to face the stop abutting part of the button element along the axial direction of the rotating sleeve.

[0020] The button element and the stop work together to constrain the movement range of the button, thereby improving the stability of the connection between the button and the intake switching component.

[0021] In some embodiments of this application, the button further includes a limiting part connected to the pressing part, and the inner wall of the rotating sleeve is provided with a mating part along the axial direction of the rotating sleeve, and the limiting part and the mating part slide and engage along the axial direction of the rotating sleeve.

[0022] The limiting part and the mating part slide together, which allows the intake switching component to drive the button to rotate, thereby ensuring that the abutting part and the stop part are always aligned in the axial direction of the rotating sleeve, thus improving the stability of the stop part and the stop abutting part.

[0023] In some embodiments of this application, the air intake switching component is provided with a recess that communicates with the interior of the rotating sleeve, and the recess is configured to accommodate the pressing part.

[0024] The pressing part is housed in the sink, which reduces the space occupied by the pressing part on the outer shell, thereby reducing the size of the aerosol device body, so as to facilitate the storage or placement of the aerosol device body.

[0025] In some embodiments of this application, the outer casing is provided with a mounting hole, the air intake switching component is provided with a rotating sleeve, the rotating sleeve is rotatably disposed in the mounting hole, the rotating sleeve is provided with a limiting protrusion and a deformation notch, the deformation notch connects the inside and outside of the rotating sleeve, and the limiting protrusion is elastically engaged with the opening at the end of the mounting hole away from the air intake switching component.

[0026] The deformation notch reduces the structural strength of the rotating sleeve at the notch location, facilitating elastic deformation of the corresponding part of the rotating sleeve. During the installation of the intake switching component, the limiting protrusion can be squeezed, causing elastic deformation of the rotating sleeve. This allows the rotating sleeve and the limiting protrusion to be inserted into the mounting hole. After the limiting protrusion moves from the end of the mounting hole furthest from the intake switching component to the outside of the mounting hole, the deformation of the rotating sleeve returns to normal, and the limiting protrusion engages with the corresponding end of the mounting hole, thus ensuring a stable connection between the rotating sleeve and the outer shell.

[0027] In some embodiments of this application, the housing is provided with a receiving groove for accommodating the intake switching component and a relief opening communicating with the receiving groove, and at least a portion of the outer peripheral wall of the intake switching component is exposed through the relief opening.

[0028] The intake switching component is housed within a receiving slot, reducing the space it occupies and thus decreasing the overall size of the aerosol device, making it easier to carry or place. When rotation of the intake switching component is required, its outer peripheral wall can be moved via the clearance port, making operation convenient and effortless.

[0029] In some embodiments of this application, the aerosol device body further includes a sealing gasket, which is disposed between the air inlet switching component and the outer shell. The sealing gasket has a connecting hole that connects the interior of the air inlet and the exterior of the outer shell. The outer shell has a plugging protrusion, and the sealing gasket has a plugging groove, into which the plugging protrusion is inserted.

[0030] The sealing gasket improves the seal between the intake switch and the housing at the intake port, thereby enhancing the accuracy of the intake switch in adjusting the intake volume and improving the sealing effect when the intake port is closed. The mating protrusion and groove of the insertion joint constrain the movement of the sealing gasket along the rotation direction of the intake switch, reducing the possibility of misalignment during rotation and ensuring that the connecting hole and the intake port remain aligned.

[0031] In some embodiments of this application, the sealing gasket is provided with a mating protrusion along the circumference of the connecting hole, and the mating protrusion abuts against the air intake switching component.

[0032] The mating convex ring can improve the sealing performance between the intake switching component and the sealing gasket, thereby further improving the sealing performance between the intake switching component and the housing.

[0033] This application also provides an aerosol device for forming an aerosol matrix. The aerosol device includes an aerosol bullet and an aerosol device body provided in any of the above embodiments. The aerosol bullet is disposed in the outer shell of the aerosol device body. The aerosol device body also includes an atomizing core, which is at least partially disposed in the air passage of the outer shell. The atomizing core is configured to form an aerosol matrix in the aerosol bullet into an aerosol.

[0034] The atomizing core causes the aerosol matrix inside the aerosol cartridge to form an aerosol. Gas from outside the outer shell flows into the air inlet through the first or second adjustment hole, causing the aerosol to be drawn out by the user along the airway away from the air inlet. The suction resistance of the aerosol device can be adjusted by rotating the air inlet switch. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0047] The terms "first," "second," and "third" used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "absorption resistance" refers to the resistance to aerosol inhalation.

[0048] The “cross section of the hole” described in this article refers to the cross section perpendicular to the direction of the hole’s penetration, and the “cross-sectional area” of the hole refers to the area of ​​the hole on the cross section of the hole.

[0049] The term "connected" in this article means that fluid in one hole can flow into the other hole.

[0050] An embodiment of this application provides an aerosol device body, including a housing, an air passage inside the housing, and an air inlet in the housing, which communicates with the air passage. The aerosol device body also includes an air inlet switching component, which covers the air inlet and is rotatably connected to the housing. The air inlet switching component has at least a first adjustment hole and a second adjustment hole, with the cross-sectional area of ​​the first adjustment hole being larger than that of the second adjustment hole. When the air inlet switching component is rotated, the first adjustment hole and the second adjustment hole can communicate with the air inlet in sequence, so that the air inlet is connected to the outside of the housing.

[0051] In use, the main body of this aerosol device can be rotated to connect the first or second adjustment hole with the air inlet by rotating the air inlet switch as needed. Since the cross-sectional area of ​​the first adjustment hole is larger than that of the second adjustment hole, aerosol devices using this main body can have different levels of suction resistance. Therefore, by carrying only one aerosol device using this main body, one can experience different levels of suction resistance; carrying a single aerosol device using this main body is more convenient than carrying two or more aerosol devices.

[0052] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Reference Figures 1 to 3 This application provides an aerosol device 1000, including an aerosol bullet (not shown) and an aerosol device body 100. The aerosol device body 100 includes a shell 11, an air inlet switching component 12, and an atomizing core (not shown). The shell 11 includes a first shell 111 and a second shell 112. The first shell 111 is fitted onto the second shell 112, and the first shell 111 and the second shell 112 are interlocked. The interior of the first shell 111 and the interior of the second shell 112 together form a closed area. The interior of the first shell 111 and the second shell 112 are provided with an air passage 1121. The end of the first shell 111 away from the second shell 112 is provided with an output nozzle 1111, and the end of the second shell 112 away from the first shell 111 is provided with an air inlet 1122. The output nozzle 1111 and the air inlet 1122 are respectively connected to both ends of the air passage 1121 and are both connected to the outside of the shell 11. It is understood that the first housing 111 and the second housing 112 are arranged opposite to each other in the extending direction of the air passage 1121.

[0054] In some embodiments, both the aerosol bullet and the atomizing core are disposed inside the first housing 111. The atomizing core includes a guide and an atomizing element, the atomizing element contacting the guide, and the guide contacting the aerosol matrix within the aerosol bullet. At least a portion of the atomizing element and the guide is located within the air passage 1121. The guide guides the aerosol matrix to flow towards the atomizing element, and the atomizing element causes the aerosol matrix to form an aerosol. External gas flows into the air passage 1121 through the air inlet 1122, causing the aerosol to flow along the air passage 1121 to the outlet nozzle 1111 and be discharged from the outlet nozzle 1111. In other embodiments, the aerosol bullet and the atomizing core may also be disposed in the second housing 112. In other embodiments, the first housing 111 and the second housing 112 may also be disposed opposite each other in an extension direction perpendicular to the air passage 1121. In other embodiments, the outer shell 11 may also be other forms of internally hollow structures.

[0055] In some embodiments, the aerosol bullet is integrally injection molded with the first housing 111. In other embodiments, the aerosol bullet may also be a structure independent of the housing 11; for example, the aerosol bullet may be detachably connected to the housing 11 by snap-fit ​​or by screws. After the aerosol matrix inside the aerosol bullet is consumed, a new aerosol bullet can be replaced, thereby improving the utilization rate of the aerosol device body 100.

[0056] In some embodiments, the aerosol device 1000 is an electronic cigarette, the guide is a sponge, the atomizing element is a heating wire, and the corresponding aerosol matrix is ​​e-liquid. In other embodiments, the aerosol device 1000 can be a medical nebulizer, the atomizing element is an ultrasonic generator, and the corresponding aerosol matrix is ​​a liquid medicine. In still other embodiments, the aerosol device 1000 can also be other types of devices.

[0057] Reference Figure 2 and Figure 3 An intake switching component 12 is disposed on the second housing 112 and covers the intake port 1122, and is rotatably connected to the second housing 112. In some embodiments, the intake switching component 12 has a first adjustment area 121, a second adjustment area 122, and a closed area 123, which are arranged sequentially along the rotation direction of the intake switching component 12; the intake switching component 12 has at least a first adjustment hole 124 and a second adjustment hole 125, with the first adjustment hole 124 disposed in the first adjustment area 121 and the second adjustment hole 125 disposed in the second adjustment area 122. For ease of description, the rotation direction of the intake switching component 12 is defined as the rotation direction R, and the axial direction of the rotation axis of the intake switching component 12 is defined as the rotation axis Z.

[0058] When the air intake switching component 12 is rotated, the first adjustment hole 124 and the second adjustment hole 125 can sequentially communicate with the air intake hole 1122, so that the air intake hole 1122 is connected to the outside of the outer casing 11. When the first adjustment area 121 moves to the air intake hole 1122, the first adjustment hole 124 can communicate with the air intake hole 1122, so that the aerosol device 1000 has a suction resistance of a first preset range; when the second adjustment area 122 moves to the air intake hole 1122, the second adjustment hole 125 can communicate with the air intake hole 1122, so that the aerosol device 1000 has a suction resistance of a second preset range. Thus, by simply carrying one such aerosol device 1000, one can experience two different levels of suction resistance when inhaling aerosols. In some other embodiments, the air intake switching component 12 can also be provided with adjustment holes of other different cross-sectional areas, so that more different levels of suction resistance can be obtained when rotating the air intake switching component 12.

[0059] Additionally, when the intake switching component 12 is rotated, the sealing area 123 can move to the intake port 1122 and seal the intake port 1122, thereby closing the air passage 1121 and keeping the air passage 1121 clean. At this time, the aerosol device 1000 is in an unusable closed mode. In some other embodiments, the sealing area 123 may be omitted. Figure 2 The first adjustment area 121, the second adjustment area 122, and the closed area 123 are respectively outlined using fan-shaped dashed frames. In other embodiments, the shape of the dashed frames used to represent the first adjustment area 121, the second adjustment area 122, and the closed area 123 may also be circular, square, or elliptical, and the positions of each dashed frame may be in other locations.

[0060] In some embodiments, along the rotation direction R, the air intake switching member 12 is adapted to adjust the overlap area of ​​the first adjustment hole 124 and the air intake hole 1122 by rotation. The overlap area of ​​the first adjustment hole 124 and the air intake hole 1122 can be understood as the area of ​​the air intake hole 1122 within the region enclosed by the first adjustment hole 124; the overlap area of ​​the first adjustment hole 124 and the air intake hole 1122 can also be understood as the overlap area of ​​the orthographic projection of the openings of the first adjustment hole 124 and the air intake hole 1122 at their closest ends in a plane perpendicular to the rotation axis Z.

[0061] In some embodiments, the first adjusting hole 124 is disposed through the rotation axis Z, and the first adjusting hole 124 extends along the rotation direction R of the air intake switching member 12 and is strip-shaped. For example, the first adjusting hole 124 is approximately waist-shaped. When the air intake switching member 12 is rotated along the rotation direction R, and the first adjusting hole 124 and the air intake hole 1122 switch from not communicating to becoming communicating, after the air intake switching member 12 is rotated further along the rotation direction R, the overlapping area of ​​the first adjusting hole 124 and the air intake hole 1122 gradually increases when viewed along the rotation axis Z, so that the opening of the air intake hole 1122 gradually increases, thereby gradually increasing the air intake volume of the air intake hole 1122. It can be understood that during the rotation of the air intake switching member 12, after the overlapping area of ​​the first adjusting hole 124 and the air intake hole 1122 increases to the maximum, the overlapping area of ​​the first adjusting hole 124 and the air intake hole 1122 gradually decreases until the first adjusting hole 124 and the air intake hole 1122 no longer overlap. For example, when the air inlet 1122 is completely moved into the area enclosed by the first adjustment hole 124, the overlap area between the first adjustment hole 124 and the air inlet 1122 is maximized.

[0062] In other embodiments, the cross-section of the first adjustment hole 124 may also be circular, elliptical, or square.

[0063] In some embodiments, the cross-section of the air inlet 1122 is generally waist-shaped, and the length direction of the cross-section of the air inlet 1122 is arranged along the rotation direction R. In other embodiments, the cross-section of the air inlet 1122 may be rectangular, elliptical, or circular.

[0064] In some embodiments, the second adjustment hole 125 is disposed through the rotation axis Z, and a plurality of second adjustment holes 125 are sequentially spaced along the rotation direction R. When the intake switching component 12 is rotated, one or more of the plurality of second adjustment holes 125 can communicate with the intake hole 1122. In some embodiments, the number of second adjustment holes 125 can be two, three or more. Taking three second adjustment holes 125 as an example, the three second adjustment holes 125 are sequentially renamed as first hole, second hole and third hole along the rotation direction R. The diameter of the first hole is smaller than the diameter of the second hole, and the diameter of the second hole is equal to the diameter of the third hole. When the intake switching component 12 is rotated, the first hole, the combination of the first hole and the second hole, the combination of the second hole and the third hole, and the third hole can sequentially communicate with the intake hole 1122, so that the intake hole 1122 is at different opening degrees. For example, the first hole communicating with the air inlet 1122 can be selected such that, when viewed along the rotation axis Z, the first hole is completely located within the area enclosed by the air inlet 1122; the combination of the first hole and the second hole communicating with the air inlet 1122 can be selected such that, when viewed along the rotation axis Z, the first hole and the second hole are completely located within the area enclosed by the air inlet 1122.

[0065] In some embodiments, the diameter of the plurality of second adjusting holes 125 may gradually increase or decrease along the rotation direction R. In some embodiments, three or more of the plurality of second adjusting holes 125 may simultaneously communicate with the air inlet 1122. In some embodiments, only one second adjusting hole 125 may be provided.

[0066] Currently, based on different levels of inhalation resistance, inhalation aerosol devices 1000 can be divided into lung-inhalation aerosol devices 1000 and mouth-inhalation aerosol devices 1000. The inhalation resistance of the lung-inhalation aerosol device 1000 is greater than that of the mouth-inhalation aerosol device 1000. Furthermore, compared to the mouth-inhalation aerosol device 1000, the lung-inhalation aerosol device 1000 has a larger adjustment range for its inhalation resistance and requires lower adjustment precision. By cooperating the first adjustment hole 124 with the air inlet hole 1122, the opening of the first adjustment hole 124 to the air inlet hole 1122 can be steplessly adjusted, resulting in a large adjustment range. It can be understood that at this time, the aerosol device 1000 is in lung-inhalation mode, and the aerosol device 1000 is a lung-inhalation aerosol device 1000. By connecting the second adjustment holes 125 of different sizes or different numbers to the air inlet 1122, the adjustment accuracy of the opening of the air inlet 1122 by the second adjustment holes 125 is higher. It can be understood that the aerosol device 1000 is in mouth-inhalation mode and the aerosol device 1000 is a mouth-inhalation aerosol device 1000.

[0067] Reference Figure 4 and Figure 5 In some embodiments, the second housing 112 is provided with a mounting hole 1123, and the intake switching component 12 is provided with a rotating sleeve 126. The rotating sleeve 126 is rotatably disposed in the mounting hole 1123, so that the intake switching component 12 is rotatably connected to the second housing 112. The rotating sleeve 126 can be understood as the rotating shaft of the intake switching component 12, and the axial direction of the rotating sleeve 126 is the rotation axis Z. In some embodiments, the rotating sleeve 126 and the intake switching component 12 are integrally injection molded, and both ends of the rotating sleeve 126 are open. In other embodiments, the intake switching component 12 can also be rotatably connected to the second housing 112 by a pin.

[0068] In some embodiments, the aerosol device body 100 further includes a circuit board 13 connected to a second housing 112. The circuit board 13 is disposed inside the second housing 112, and the second housing 112 is provided with a button element 131, which is disposed facing the mounting hole 1123. It is understood that the button element 131 is disposed on the side of the circuit board 13 facing the mounting hole 1123, and in the rotational axis Z, the button element 131 is aligned with the mounting hole 1123.

[0069] In some embodiments, the rotating sleeve 126 is provided with a limiting protrusion 1261 and a deformation notch 1262. The deformation notch 1262 connects the interior and exterior of the rotating sleeve 126, and the limiting protrusion 1261 protrudes from the outer peripheral wall of the rotating sleeve 126. The deformation notch 1262 can reduce the structural strength of the rotating sleeve 126 at the deformation notch 1262, facilitating elastic deformation of the corresponding part of the rotating sleeve 126. When installing the air intake switching component 12, the limiting protrusion 1261 can be squeezed to cause the rotating sleeve 126 to undergo elastic deformation, so that the rotating sleeve 126 and the limiting protrusion 1261 can be inserted into the mounting hole 1123. After the limiting protrusion 1261 moves from the end of the mounting hole 1123 away from the air intake switching component 12 to the outside of the mounting hole 1123, the deformation of the rotating sleeve 126 is restored, and the limiting protrusion 1261 is engaged with the opening at the corresponding end of the mounting hole 1123, thereby enabling a stable connection between the rotating sleeve 126 and the outer shell 11. In some embodiments, the deformable notch 1262 penetrates the end wall of the rotating sleeve 126 near the end of the button element 131.

[0070] Reference Figure 3 and Figure 6 In some embodiments, the aerosol device body 100 further includes a sealing gasket 14, which is disposed between the air intake switching member 12 and the second housing 112. The second housing 112 is provided with a plugging protrusion 1124, and the sealing gasket 14 is provided with a plugging groove 141 and a connecting hole 142. The plugging protrusion 1124 is inserted into the plugging groove 141, and the connecting hole 142 connects the interior of the air intake port 1122 and the exterior of the housing 11. In some embodiments, the sealing gasket 14 is provided with a mating protrusion 143 along the circumference of the connecting hole 142, and the mating protrusion 143 abuts against the air intake switching member 12.

[0071] The mating protrusion 143 improves the sealing performance between the intake switching component 12 and the sealing gasket 14, thereby further enhancing the sealing performance between the intake switching component 12 and the housing 11. The insertion protrusion 1124 engages with the insertion groove 141 to constrain the movement of the sealing gasket 14 along the rotation direction R, thereby reducing the possibility of the sealing gasket 14 shifting when the intake switching component 12 rotates, and ensuring that the connecting hole 142 and the intake hole 1122 remain aligned. In addition, by filling the gap between the intake switching component 12 and the second housing 112 with the sealing gasket 14, the limiting protrusion 1261 and the opening of the mounting hole 1123 remain engaged, thereby improving the stability of the intake switching component 12's rotation relative to the second housing 112.

[0072] Reference Figure 1 and Figure 4In some embodiments, the second housing 112 is provided with a receiving groove 1125 for accommodating the air intake switching component 12 and a relief opening 1126 communicating with the receiving groove 1125, with at least a portion of the outer peripheral wall of the air intake switching component 12 exposed through the relief opening 1126. By accommodating the air intake switching component 12 within the receiving groove 1125, the space occupied by the air intake switching component 12 can be reduced, thereby reducing the volume of the aerosol device body 100 for easy carrying or placement. When it is necessary to rotate the air intake switching component 12, the outer peripheral wall of the air intake switching component 12 can be moved through the relief opening 1126 to rotate the air intake switching component 12, making the operation convenient and effortless.

[0073] Reference Figure 3 and Figure 7 In some embodiments, the aerosol device body 100 further includes a button 15, which is inserted into the rotating sleeve 126 and can slide along the rotation axis Z. When the button 15 slides toward the button element 131, the button 15 can press the button element 131 to trigger it. In some embodiments, the button element 131 is configured to adjust the power of the atomizing element of the atomizing core. Exemplarily, by continuously pressing the button 15, the power of the atomizing element gradually increases. When the power of the atomizing element reaches its maximum value, pressing the button 15 again changes the power of the atomizing element to its minimum value. In other embodiments, the aerosol device body 100 is provided with a display screen, and the button element 131 can be configured to turn the display screen on or off by pressing the button 15. In other embodiments, the button element 131 can also be configured for other functions.

[0074] In some embodiments, the button 15 includes a pressing portion 151, a contact portion 152, an abutting portion 153, and a connecting portion 154. The connecting portion 154 is inserted into the rotating sleeve 126. The contact portion 152 is connected to one end of the connecting portion 154 near the button element 131. The pressing portion 151 is connected to the other end of the connecting portion 154. The abutting portion 153 is disposed between the contact portion 152 and the pressing portion 151 and is connected to the connecting portion 154. The rotating sleeve 126 is provided with a stop portion 1263, which is configured to stop the abutting portion 153 of the button element 131 along the rotation axis Z. When installing button 15, after inserting one end of connecting part 154 near contact part 152 into rotating sleeve 126, press pressing part 151 firmly, and abutting part 153 can abut against the inner wall of rotating sleeve 126 and push rotating sleeve 126, so that rotating sleeve 126 elastically bends and deforms in a direction away from its own axis, so that abutting part 153 protrudes from one end of rotating sleeve 126 near button element 131.

[0075] When the pressing part 151 is pressed, the connecting part 154 causes the contact part 152 to move, so that the contact part 152 abuts against the button element 131 to trigger the button element 131. After the pressing part 151 is released, when the connecting part 154 moves away from the button element 131, the stop part 1263 abuts against the abutting part 153 to limit the movement of the connecting part 154. The button element 131 and the stop part 1263 work together to constrain the movement range of the button 15, thereby improving the stability of the connection between the button 15 and the air intake switch 12. In some embodiments, the connecting part 154 may be omitted, and the abutting part 153 and the contact part 152 are connected to the pressing part 151.

[0076] Reference Figure 6 and Figure 7 In some embodiments, the button 15 further includes a limiting portion 155, which is disposed between the abutting portion 153 and the pressing portion 151, and is connected to the connecting portion 154. The inner wall of the rotating sleeve 126 is provided with a mating portion 1264 along the rotation axis Z, and the limiting portion 155 and the mating portion 1264 slide in engagement along the rotation axis Z. This sliding engagement of the limiting portion 155 and the mating portion 1264 allows the air intake switching component 12 to rotate the button 15, thereby ensuring that the abutting portion 153 and the stop portion 1263 remain aligned along the rotation axis Z, thus improving the stability of the stop portion 1263 against the abutting portion 153. In some embodiments, the limiting portion 155 is protruding, and the mating portion 1264 is recessed. In other embodiments, the limiting portion 155 may be recessed, and the mating portion 1264 may be protruding. In other embodiments, the limiting part 155 may be connected to the pressing part 151. Figure 6 The dashed line in the figure is used to separate the connecting portion 154 and the limiting portion 155. In other embodiments, the dashed line used to separate the connecting portion 154 and the limiting portion 155 may also be of other shapes or located in other positions.

[0077] In some embodiments, the air intake switching member 12 is provided with a recess 127 communicating with the interior of the rotating sleeve 126. The recess 127 extends through the sidewall of the air intake switching member 12 on the side away from the button element 131 along the rotation axis Z. The recess 127 is configured to accommodate the pressing part 151. The pressing part 151 is accommodated in the recess 127, which reduces the space occupied by the pressing part 151 on the exterior of the housing 11, thereby reducing the size of the aerosol device body 100, so as to facilitate the storage or placement of the aerosol device body 100.

[0078] Reference Figure 5 and Figure 8In some embodiments, the second housing 112 is provided with an elastic protrusion 1127. The elastic protrusion 1127 is elastic and undergoes elastic deformation after being subjected to force. The intake switching component 12 is provided with an operating ring 128 and a plurality of limiting grooves 129. The operating ring 128 covers the elastic protrusion 1127, and the inner peripheral wall of the operating ring 128 is provided with a clearance groove 1281. The elastic protrusion 1127 is located in the clearance groove 1281. The inner sidewall of the clearance groove 1281 is provided with a plurality of mating protrusions 1281a at intervals along the rotation direction R. The mating protrusions 1281a correspond one-to-one with the limiting grooves 129. Each limiting groove 129 is provided on the sidewall of the corresponding mating protrusion 1281a facing the rotation axis of the intake switching component 12. The clearance groove 1281 has a certain limiting effect on the elastic protrusion 1127, which can constrain the rotation range of the intake switching component 12.

[0079] In some embodiments, the elastic protrusion 1127 is bent towards the rotation axis of the intake switching member 12 on both sides along the rotation direction R. When the intake switching member 12 is rotated, the elastic protrusion 1127 can abut against the mating protrusion 1281a. Under the action of the reverse force of the mating protrusion 1281a, the elastic protrusion 1127 undergoes elastic deformation towards the rotation axis of the intake switching member 12, so that the elastic protrusion 1127 abuts against the side wall of the mating protrusion 1281a towards the rotation axis of the intake switching member 12. When the elastic protrusion 1127 is aligned with the limiting groove 129, the deformation of the elastic protrusion 1127 is restored, so that the elastic protrusion 1127 is inserted into the corresponding limiting groove 129 to limit further rotation of the intake switching member 12, thereby making the first adjusting hole 124 or the second adjusting hole 125 stably cooperate with the intake hole 1122.

[0080] In some embodiments, the operating ring 128 may be omitted, the limiting groove 129 may be provided on the side wall of the intake switching member 12 along the rotation axis Z and facing the second housing 112, and the elastic protrusion 1127 may be provided on the side wall of the second housing 112 along the rotation axis Z and facing the intake switching member 12. In some other embodiments, the elastic protrusion 1127 may be provided on the intake switching member 12, and the limiting groove 129 may be provided on the second housing 112.

Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
