Description

Technical Field

[0001] This application relates to, but is not limited to, the field of atomizing devices, and particularly to an electronic atomizing device. Background Technology

[0002] Electronic atomizing devices typically consist of a main body and an atomizing component. The main body powers the atomizing component, which atomizes the atomizing medium into an aerosol. The atomizing medium can be a liquid, paste, or other similar substance. When an electronic atomizing device is operating, outside air enters and mixes with the atomized medium to form an aerosol. However, the amount of outside air entering is difficult to control, which is detrimental to the use of electronic atomizing devices. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this application provides an electronic atomizing device. This application achieves this through the following technical solution:

[0004] This application provides an electronic atomizing device, including a device body, an atomizing component, and a first sealing member. The device body has a first airflow channel; the atomizing component has a second airflow channel and is connected to the device body; the first sealing member is sealed between the device body and the atomizing component, and the first sealing member has a third airflow channel to connect the first airflow channel and the second airflow channel.

[0005] The electronic atomizing device provided in this application embodiment includes a device body and an atomizing component. The device body has a first airflow channel, and the atomizing component has a second airflow channel. When the atomizing component is connected to the device body, airflow can flow in the first and second airflow channels. Furthermore, the electronic atomizing device also includes a first sealing element, which is sealed between the atomizing component and the device body to block the gap between them. The first sealing element has a third airflow channel, which connects the first and second airflow channels, providing a good sealing effect. Airflow is not easily leaked and is confined to a small space, resulting in a more uniform air pressure distribution, lower airflow resistance, easier control, and less noise generation. The design of the electronic atomizing device is less affected by the gap between the atomizing component and the device body, allowing for more flexible design. Airflow and resistance can also be controlled by flexibly designing the cross-sectional area of ​​the third airflow channel, contributing to an improved user experience.

[0006] In one possible implementation of this application, the first airflow channel includes an airflow cavity, and the first seal includes a first structural part, which is disposed in the airflow cavity and fits against the peripheral inner wall of the airflow cavity.

[0007] Here, the first structural part is placed inside the airflow cavity and is fitted against the inner wall of the airflow cavity. The two have a large contact area, thereby isolating the gap between the airflow cavity and the device body and the atomizing component to provide good sealing performance.

[0008] In one possible implementation of this application, the device body further includes a protruding structure disposed in the airflow cavity, and the first sealing member includes a relief groove disposed corresponding to the protruding structure, the relief groove being sleeved on the protruding structure.

[0009] Here, the device body also includes a protruding structure disposed in the airflow cavity. The first sealing member is provided with an avoidance groove corresponding to the protruding structure. On the one hand, it can avoid the protruding structure. On the other hand, the avoidance groove is sleeved on the protruding structure, and the two can limit each other to improve the connection stability between the first sealing member and the device body.

[0010] In one possible implementation of this application, the device body is provided with a first limiting surface, the first seal is provided with at least one elastic limiting portion, the elastic limiting portion has a second limiting surface, and when the first seal is assembled to the device body, the first limiting surface and the second limiting surface abut against each other at least along the assembly direction of the device body and the first seal.

[0011] Here, the device body is provided with a first limiting surface, and the first sealing member has an elastic limiting part. The second limiting surface of the elastic limiting part can abut against the second limiting surface, thereby restricting the first sealing member from coming out of the device body, improving the connection stability between the first sealing member and the device body, and thus improving the sealing effect.

[0012] In one possible implementation of this application, the first airflow channel includes an airflow cavity located on the side of the device body away from the atomizing component, the first limiting surface is the inner wall of the airflow cavity, and at least a portion of the elastic limiting portion is accommodated in the airflow cavity.

[0013] Here, at least part of the elastic limiting part is housed in the airflow cavity, which facilitates the contact between the first limiting surface and the second limiting surface, resulting in more balanced force distribution. The elastic limiting part is less likely to detach from the device body, and it also helps to reduce the volume of the airflow cavity, thereby optimizing the airflow distribution.

[0014] In one possible implementation of this application, the device body further includes a mounting groove located on the side of the device body near the atomizing component, and at least a portion of the first seal is accommodated in the mounting groove.

[0015] Here, by setting the mounting groove, on the one hand, it is convenient to assemble the first seal with the device body and to limit the mutual positioning of the two; on the other hand, at least part of the first seal is accommodated in the mounting groove, which also helps to reduce space occupation and facilitates the miniaturization of the device.

[0016] In one possible implementation of this application, at least a portion of the first seal is accommodated in the mounting groove, and the device body further includes a protrusion structure disposed in the mounting groove, with the first seal having an avoidance groove corresponding to the protrusion structure.

[0017] Here, the device body includes a protruding structure disposed in the mounting groove, and the first seal is provided with a relief groove corresponding to the protruding structure of the mounting groove. On the one hand, it can avoid the protruding structure, and on the other hand, the relief groove and the protruding structure can limit each other to improve the connection stability between the first seal and the device body.

[0018] In one possible implementation of this application, the first seal includes a second structural portion that extends into the second airflow channel and fits against the peripheral inner wall of the second airflow channel.

[0019] Here, the second structural part extends into the second airflow channel and fits against the inner wall of the second airflow channel. The two have a large contact area, thereby isolating the gap between the second airflow channel and the device body and the atomizing component to provide good sealing performance.

[0020] In one possible implementation of this application, the electronic atomizing device further includes a magnetic structure disposed between the device body and the atomizing component. The first sealing member cooperates with the magnetic structure to fix the atomizing component and the device body relatively.

[0021] Here, by setting up a magnetic attraction structure, the first seal and the magnetic attraction structure are combined to provide effective limiting for the atomizing component and the device body, thereby improving the connection stability of the atomizing component and the device body.

[0022] In one possible implementation of this application, the device body has a receiving cavity, at least a portion of the atomizing component extends into the receiving cavity, and the atomizing component is detachably connected to the device body.

[0023] Here, at least part of the atomizing component extends into the receiving cavity, which helps to improve space utilization, and the atomizing component is detachably connected to the device body, which facilitates the maintenance of the electronic atomizing device.

[0024] In one possible implementation of this application, the device body further includes a conductive element, and the first sealing element has a through hole through which the conductive element passes to connect to the atomizing component.

[0025] Here, the first seal has a through hole, which allows the conductive component to pass through and connect to the atomizing assembly. Furthermore, the conductive component can serve as a positioning or guiding member to facilitate the assembly of the first seal with the device body. The conductive component and the through hole can also cooperate to form a limiting mechanism, thereby improving the connection stability between the first seal and the device body.

[0026] In one possible implementation of this application, the first seal further includes a first sealing ring that surrounds the through hole and abuts against the atomizing assembly.

[0027] Here, the first sealing element is provided with a first sealing ring, which surrounds the periphery of the through hole and abuts against the atomizing component, thereby isolating the through hole from the gap between the atomizing component and the device body to improve sealing performance.

[0028] In one possible implementation of this application, the first seal further includes a first sealing ring, which abuts against the atomizing assembly, and the through hole and the third airflow channel are both located inside the first sealing ring.

[0029] Here, by setting a first sealing ring, the through hole and the third airflow channel are both located inside the first sealing ring. The isolation of multiple holes or channels is achieved by a single first sealing ring, which is simple in structure and easy to implement.

[0030] In one possible implementation of this application, the first airflow channel includes an airflow cavity, and the device body also has a sensing channel communicating with the airflow cavity, and the sensing channel is connected to an airflow sensor; a first protrusion is provided inside the airflow cavity, the first protrusion protrudes relative to the bottom wall of the airflow cavity, and the opening of the sensing channel is provided on the first protrusion.

[0031] Here, by setting the first protrusion, the opening of the sensing channel is located on the first protrusion, so that the opening of the sensing channel is higher than the bottom wall of the airflow cavity, which can prevent the liquid in the airflow cavity from flowing into the sensing channel and protect the airflow sensor.

[0032] In one possible implementation of this application, the first airflow channel includes an airflow cavity, the device body forms a receiving cavity for receiving a battery and / or electronic control components, and the receiving cavity is connected to the airflow cavity; the device body also has a sensing channel, the sensing channel is connected to an airflow sensor, and the sensing channel is connected to the receiving cavity.

[0033] Here, the airflow cavity and the sensing channel are connected through the housing cavity. The airflow in the airflow cavity will drive the airflow in the housing cavity, thereby forming an airflow that can cool the battery and / or electronic control components in the housing cavity.

[0034] In one possible implementation of this application, the device body includes a housing and a support, the support being housed within the housing, and the first airflow channel includes a channel segment formed by the housing and the support; the electronic atomizing device further includes a second seal, which is sealed between the support and the housing, and the second seal is located on the side of the channel segment closer to the atomizing component.

[0035] Here, by setting a second seal between the housing and the bracket, the second seal is located on the side of the channel section closer to the atomizing component, thereby isolating the channel section from the gap between the atomizing component and the device body, providing good sealing performance.

[0036] In one possible implementation of this application, the electronic atomizing device further includes a third seal, which is sealed between the bracket and the housing, and the third seal is located on the side of the channel segment away from the atomizing component.

[0037] Here, by placing a third seal between the housing and the bracket, located on the side of the channel segment away from the atomizing assembly, the channel segment is isolated from other gaps between the bracket and the housing, thus providing good sealing performance.

[0038] In one possible implementation of this application, the channel segment surrounds the bracket circumferentially, and the channel segment includes a first opening in the bracket and a second opening in the housing, the first opening and the second opening being spaced apart circumferentially from the bracket.

[0039] Here, the channel section surrounds the circumference of the support, which facilitates the processing of the channel section. On the other hand, since the first opening and the second opening are spaced apart along the circumference of the support, and there is a long distance between them, the outflow of condensate and other substances in the channel section can be reduced.

[0040] In one possible implementation of this application, the first airflow channel includes an airflow cavity and a second opening. The second opening is disposed in the housing. At least one side of the airflow cavity passes through the support and extends into the housing. The second opening is connected to the airflow cavity through at least one channel segment.

[0041] Here, the airflow cavity is connected to the support, which facilitates the connection between the airflow cavity and the second opening. The second opening can be connected to the airflow cavity through one or more channel segments, which facilitates the flow of airflow between the second opening and the airflow cavity.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0067] This application provides an electronic atomizing device. By setting a first sealing element, when the atomizing component is connected to the device body, the first sealing element is sealed between the first surface and the second surface. The first airflow channel and the second airflow channel are connected through the third airflow channel of the first sealing element, which has a good sealing effect, the airflow is not easy to leak and is easy to control, and the space through which the airflow flows is small, the frictional resistance is small and it is not easy to generate noise. The air pressure distribution is relatively uniform, which helps to improve the user experience of the electronic atomizing device.

[0068] Reference Figure 1 , Figure 2 and Figure 3 The electronic atomizing device according to this application embodiment includes a device body 100, an atomizing component 200, and a first sealing member 300, as shown in the reference. Figure 4 and Figure 5 The device body 100 has a first airflow channel 160; the atomizing component 200 has a second airflow channel 210 and is connected to the device body 100; the first sealing member 300 is sealed between the device body 100 and the atomizing component 200, and the first sealing member 300 has a third airflow channel 310 to connect the first airflow channel 160 and the second airflow channel 210.

[0069] In this embodiment, the device body 100 may include power supply components, such as a battery and a conductive interface. The device body 100 may also include control components, such as a circuit board, a controller, and a sensor. For example, see reference to... Figure 5 The sensor may include an airflow sensor 400, which is used to sense the airflow in the first airflow channel 160. The controller responds to the sensing result of the airflow sensor 400 to control the electronic atomization device to start.

[0070] In this embodiment, the atomizing component 200 may include a receiving cavity for containing the atomizing medium, and the atomizing component 200 may also include an atomizer disposed in the atomizing cavity 230. The atomizer atomizes the atomizing medium under the drive of the power supply component and the control component. The atomizer may be ultrasonic, electrically heated, or the like.

[0071] In this embodiment, the connection between the atomizing component 200 and the device body 100 can be a non-detachable connection such as bonding, welding, or riveting; or a detachable connection such as snap-fit, threaded connection, fastener connection, or magnetic connection. It is understood that a detachable connection between the atomizing component 200 and the device body 100 allows for easy replacement of the atomizing component 200, which is a consumable, resulting in good environmental and economic benefits. For example, the atomizing component 200 and the device body 100 are magnetically connected.

[0072] In this embodiment, the device body 100 may include a first surface 110, and the first airflow channel 160 includes an opening disposed on the first surface 110; the atomizing component 200 may include a second surface 220, and the second airflow channel 210 includes an opening disposed on the second surface 220. When the atomizing component 200 is connected to the device body 100, the first surface 110 and the second surface 220 are opposite to each other, so that the first airflow channel 160 and the second airflow channel 210 are connected through the third airflow channel 310 of the first seal 300.

[0073] In this embodiment, the second airflow channel 210 is an airflow path connecting the air inlet and air outlet of the atomizing assembly 200. The air inlet of the second airflow channel 210 is located on the second surface 220, and the air outlet of the second airflow channel 210 is located at the end of the atomizing assembly 200 away from the device body 100. The portion of the atomizing assembly 200 with the air outlet can be used as the mouthpiece of an electronic atomizing device.

[0074] In this embodiment, the first sealing member 300 is sealed between the atomizing component 200 and the device body 100. That is, the first sealing member 300, through its tight fit with the atomizing component 200 and the device body 100, isolates the gap between the first surface 110 and the second surface 220 relative to the first airflow channel 160 and the second airflow channel 210. The first airflow channel 160 and the second airflow channel 210 cannot communicate with the outside world through the gap between the first surface 110 and the second surface 220.

[0075] In this embodiment, the first sealing member 300 can have multiple possible connection forms. The first sealing member 300 can be connected to the device body 100 and tightly fitted to the surface of the atomizing component 200; the first sealing member 300 can also be connected to the atomizing component 200 and tightly fitted to the surface of the device body 100; or, the first sealing member 300 can be connected to both the device body 100 and the atomizing component 200.

[0076] In this embodiment, the tight fit between the first sealing element 300 and the device body 100 can be either the first sealing element 300 fitting with the first surface 110 or the first sealing element 300 fitting with other parts of the device body 100; correspondingly, the tight fit between the first sealing element 300 and the atomizing component 200 can be either the first sealing element 300 fitting with the second surface 220 or the first sealing element 300 fitting with other parts of the atomizing component 200.

[0077] In this embodiment, the first sealing member 300 has various possible structural forms and placement positions. In one example, the first sealing member 300 is located between the first surface 110 and the second surface 220. The first sealing member 300 can also extend to the periphery of the device body 100 and / or the atomizing component 200 to be fitted onto the device body 100 and / or the atomizing component 200. In another example, the first sealing member 300 is housed in the device body 100, the second surface 220 of the atomizing component 200 is in contact with the first surface 110 of the device body 100, and the side of the first sealing member 300 near the atomizing component 200 is also in contact with the second surface 200, that is, the second surface 220 is in contact with both the first sealing member 300 and the first surface 110.

[0078] In another example, a portion of the first seal 300 is housed in the device body 100, while another portion protrudes from the first surface 110 and is combined with the atomizing assembly 200, i.e., both ends of the first seal 300 are connected to the device body 100 and the atomizing assembly 200, respectively.

[0079] In this embodiment, the first sealing element 300 can be a split structure or an integral structure. For example, the first sealing element 300 is integrally molded from an elastic material such as rubber. It is understood that the elastically configured first sealing element 300 can improve the tightness of its connection with the atomizing component 200 / device body 100 through elastic deformation, thereby enhancing the sealing effect.

[0080] In this embodiment, the third airflow channel 310 connects the second airflow channel 210 and the first airflow channel 160. The third airflow channel 310 can be a constant diameter hole, a variable diameter hole, a stepped hole, etc. The radial cross-section of the third airflow channel 310 can be circular, elliptical, rectangular, square, triangular, rhomboid, regular hexagonal, trapezoidal, etc. The extending axis of the third airflow channel 310 can be a straight line, a curve, a spiral, etc. For example, the third airflow channel 310 is opened in the middle of the first sealing member 300, and its extending axis is arranged along the relative direction of the first surface 110 and the second surface 220. The radial cross-section of the third airflow channel 310 is elongated.

[0081] The technical solution provided in this application embodiment includes a device body 100 and an atomizing component 200. The device body 100 has a first airflow channel 160, and the atomizing component 200 has a second airflow channel 210. When the atomizing component 200 is connected to the device body 100, the first surface 110 of the device body 100 and the second surface 220 of the atomizing component 200 are opposite to each other, so that airflow flows through the first airflow channel 160 and the second airflow channel 210.

[0082] Based on this, the electronic atomizing device is provided with a first sealing element 300, which is sealed between the device body 100 and the atomizing component 200, thereby sealing the gap between the device body 100 and the atomizing component 200. The first sealing element 300 has a third airflow channel 310, and the first airflow channel 160 and the second airflow channel 210 are connected through the third airflow channel 310, which has a good sealing effect.

[0083] Compared to technical solutions where gaps may exist at the connection between the atomizing component 200 and the device body 100, leading to airflow leakage and uneven air pressure distribution, the setting of the first sealing element 300 reduces the possibility of airflow leakage and confines the airflow to a smaller space, resulting in a more uniform air pressure distribution.

[0084] Compared to the technical solution where the gap between the atomizing component 200 and the device body 100 is used as an airflow channel, the airflow has a large flow area, is subject to greater frictional resistance, is difficult to control, and is prone to generating narrow gap noise, the setting of the first sealing element 300 reduces the resistance to airflow and reduces the area of ​​the airflow channel, making the airflow easier to control and less likely to generate noise.

[0085] Furthermore, due to the setting of the first seal 300, the design of the electronic atomizing device is less affected by the gap between the atomizing component 200 and the device body 100, making the design more flexible. The airflow and resistance can also be controlled by flexibly designing the cross-sectional area of ​​the third airflow channel 310, which helps to improve the user experience of the electronic atomizing device.

[0086] To improve the sealing effect, refer to Figure 4 and Figure 5 In some possible embodiments of this application, the first airflow channel 160 includes an airflow cavity 120, and the third airflow channel 310 is located within the airflow cavity 120. This arrangement, with the airflow cavity 120 being the larger portion of the first airflow channel 160 and the third airflow channel 310 located within it, helps reduce the required assembly precision between the first seal 300 and the device body 100, facilitating the assembly of the first seal 300 with the device body 100.

[0087] Reference Figure 4 and Figure 5 In some possible embodiments of this application, the first seal 300 includes a first structural part 320, which is disposed in the airflow cavity 120 and fits against the peripheral inner wall of the airflow cavity 120.

[0088] In some examples, the airflow cavity 120 can be formed on the first surface 110 of the device body 100, that is, the airflow cavity 120 is formed by a recess in the first surface 110; in other examples, the airflow cavity 120 can also be disposed on the side of the device body 100 opposite to the first surface 110. In addition, the airflow cavity 120 can also be disposed inside the device body 100 and connected to the first surface 110 by the first airflow channel 160. In this technical solution, the first seal 300 is located outside the airflow cavity 120.

[0089] In this embodiment, the airflow cavity 120 can be used as the airflow sensing cavity of the electronic atomizing device to connect with the airflow sensor 400. When the user inhales through the second airflow channel 210, the airflow flows from the airflow cavity 120 to the second airflow channel 210 to form a negative pressure in the airflow cavity 120, thereby triggering the airflow sensor 400.

[0090] In this embodiment, the first seal 300 includes a first structural portion 320 extending into the airflow cavity 120 to mount the first seal 300 to the device body 100. On one hand, the first seal 300 improves the airtightness of the airflow cavity 120 and enhances the stability of the air pressure. On the other hand, the first structural portion 320 extending into the airflow cavity 120 can reduce the volume of the airflow cavity 120, which is beneficial for the uniform distribution of airflow. Both aspects can improve the air pressure and stability of the airflow, thus facilitating the triggering of the airflow sensor 400.

[0091] In this embodiment, the first structural portion 320 may be partially or entirely disposed within the airflow cavity 120. The first structural portion 320 and the bottom wall of the airflow cavity 120 (relative to the inner wall of the second surface 220) may be spaced apart or partially attached. For example, the first structural portion 320 is entirely disposed within the airflow cavity 120, and the surface of the first structural portion 320 near the second surface 220 is flush with the first surface 110.

[0092] In some possible embodiments, the first surface 110 of the device body 100 is attached to the second surface 220 of the atomizing component 200, and the surface of the first seal 300 is flush with the first surface 110 and the second surface 220, that is, the second surface 220 is attached to the first surface 110 and the first seal 300 respectively, so as to reduce the gap between the device body 100 and the atomizing component 200.

[0093] In this embodiment, the first structural portion 320 is fitted to the peripheral inner wall of the airflow cavity 120, that is, the peripheral outer wall of the first structural portion 320 and the peripheral inner wall of the airflow cavity 120 have similar structures and sizes, and can fit tightly together. For example, the outer peripheral contour of the first surface 110 and the outer peripheral contour of the airflow cavity 120 are both rectangular, and the two are fitted with an interference fit.

[0094] In this embodiment, an annular protrusion is provided on at least one of the peripheral outer wall of the first structural portion 320 and the peripheral inner wall of the airflow cavity 120 to further improve the sealing effect. The annular protrusion can be one or more, and multiple annular protrusions are spaced apart axially along the third airflow channel 310.

[0095] For example, a second sealing ring 370 is provided around the peripheral outer wall of the first structural part 320. The second sealing ring 370 is made of an elastic material, such as rubber. When the first structural part 320 is assembled to the airflow cavity 120, the second sealing ring 370 elastically deforms to fit tightly against the peripheral inner wall of the airflow cavity 120.

[0096] It is understandable that the tight connection between the first structural part 320 and the airflow cavity 120 can provide a good air seal to ensure stable airflow. On the other hand, it can also provide functions such as dust prevention, leakage prevention, and sound insulation, for example, preventing the atomizing medium of the atomizing component 200 from flowing into the device body 100.

[0097] The technical solution provided in this application embodiment involves placing the first structural part 320 inside the airflow cavity 120 and making the first structural part 320 fit against the peripheral inner wall of the airflow cavity 120, so that the two have a large contact area, thereby isolating the gap between the airflow cavity 120 and the device body 100 and the atomizing component 200, so as to provide good sealing performance.

[0098] To improve connection stability, refer to Figure 12 and Figure 13 In some possible embodiments of this application, the device body 100 is provided with a first limiting surface 154, and the first sealing member 300 is provided with at least one elastic limiting portion 380. The elastic limiting portion 380 has a second limiting surface 381. When the first sealing member 300 is assembled to the device body 100, the first limiting surface 154 and the second limiting surface 381 abut against each other at least along the assembly direction of the device body 100 and the first sealing member 300.

[0099] In this embodiment, the elastic limiting part 380 can be an elastic buckle, an elastic protrusion, etc. The elastic limiting part 380 can undergo elastic deformation under the action of external force, and restore its inherent shape by relying on elastic force when the external force is removed. Specifically, the elastic limiting part 380 undergoes elastic deformation during the process of the device moving to the device body 100, so as to pass through the first limiting surface 154; when the first sealing member 300 is installed in place relative to the device body 100, the elastic limiting part 380 restores its inherent shape and causes the second limiting surface 381 to abut against the first limiting surface 154, thereby restricting the movement of the first sealing member 300 relative to the device body 100.

[0100] In this embodiment, the first limiting surface 154 and the second limiting surface 381 can be perpendicular to the assembly direction of the first sealing member 300 relative to the device body 100, or they can form an acute or obtuse angle with the assembly direction. The first limiting surface 154 and the second limiting surface 381 can be arranged parallel to each other, and when the first sealing member 300 is assembled to the device body 100, the first limiting surface 154 and the second limiting surface 381 are in contact.

[0101] In this embodiment, the assembly direction of the device body 100 and the first seal 300 can be the direction in which the device body 100 approaches or moves away from the atomizing component 200; the assembly direction of the device body 100 and the first seal 300 can also be associated with the axial direction of the third airflow channel 310. For example, the assembly direction of the device body 100 and the first seal 300 is parallel to the axial direction of the third airflow channel 310, thereby reducing the possibility that the airflow will cause the first seal 300 to detach from the device body 100 under the action of the first limiting surface 154 and the second limiting surface 381.

[0102] The technical solution provided in this application embodiment includes a first limiting surface 154 on the device body 100 and an elastic limiting portion 380 on the first sealing member 300. The second limiting surface 381 of the elastic limiting portion 380 can abut against the second limiting surface 381, thereby restricting the first sealing member 300 from coming out of the device body 100, improving the connection stability between the first sealing member 300 and the device body 100, and thus improving the sealing effect.

[0103] To optimize the structure of the airflow cavity 120, refer to... Figure 13 , Figure 14 and Figure 15 In some possible embodiments of this application, the first airflow channel 160 includes an airflow cavity 120, which is located on the side of the device body 100 away from the atomizing component 200. The first limiting surface 154 is the inner wall of the airflow cavity 120, and at least a portion of the elastic limiting portion 380 is accommodated in the airflow cavity 120.

[0104] In some embodiments, the first seal 300 may not be located in the airflow cavity 120, or the portion of the first seal 300 located in the airflow cavity 120 may not be in contact with the peripheral inner wall of the airflow cavity 120. For example, a portion of the elastic limiting portion 380 of the first seal 300 may be located in the airflow cavity 120 and may not be in contact with the cavity wall of the airflow cavity 120.

[0105] In this embodiment, the first limiting surface 154 can be the inner wall of the device body 100 forming the airflow cavity 120, or the device body 100 may have a recess or protrusion formed on the inner side corresponding to the airflow cavity 120, and the first limiting surface 154 is the surface of the recess or protrusion. For example, the first limiting surface 154 is the surface of the device body 100 away from the atomizing component 200.

[0106] In this embodiment, the elastic limiting part 380 can be inserted into a portion of the structure of the device body 100. For example, the elastic limiting part 380 can be inserted from the side of the device body 100 near the atomizing device 200 into the airflow cavity 120. The device body 100 is provided with a through hole corresponding to the elastic limiting part 380, and the outer wall of the elastic limiting part 380 fits against the inner wall of the through hole to achieve a good sealing effect. The cross-sections of the elastic limiting part 380 and the through hole can be regular or irregular shapes such as circles, squares, and triangles.

[0107] In this embodiment, the periphery of the elastic limiting portion 380 may be provided with a protrusion or a recess, and the second limiting surface 381 is the surface of the protrusion or recess. (Refer to...) Figure 12 and Figure 16 In some examples, the first seal 300 includes a third structural portion 390 and an elastic limiting portion 380 extending from the third structural portion 390 toward the airflow cavity 120. The elastic limiting portion 380 includes a flange structure 382, ​​and a second limiting surface 381 is formed on the side of the flange structure 382 near the third structural portion 390. That is, the third structural portion 390 and the flange structure 382 clamp and fix the device body 100 from opposite sides.

[0108] In this embodiment, the radial dimension of the flange structure 382 can gradually decrease in the direction away from the third structural part 390, that is, the axial cross section of the flange structure 382 is an inverted trapezoid or triangle. On the one hand, this facilitates elastic deformation of the flange structure 382 during the assembly process with the device body 100, and on the other hand, it enhances the load-bearing capacity of the flange structure 382 on the side of the second limiting surface 381.

[0109] In this embodiment, an extension structure 383 may be provided at the end of the flange structure 382 away from the third structural part 390. On the one hand, the extension structure 383 can occupy the space of the airflow cavity 120, reducing the volume of the airflow cavity 120. On the other hand, the longer extension structure 383 facilitates the alignment of the elastic limiting part 380 and the corresponding through hole. In addition, the end of the extension structure 383 away from the flange structure 382 may adopt a conical structure or a hemispherical structure to guide the extension structure 383 into the through hole.

[0110] In this embodiment, there may be one or more elastic limiting portions 380, and the multiple elastic limiting portions 380 may be arranged in an array about the surface of the third structural portion 390, such as a rectangular array or a circular array. (Refer to...) Figure 12 and Figure 15 There are four elastic limiting parts 380, which are arranged in a rectangular array.

[0111] In this embodiment, the airflow cavity 120 is located on the side of the device body 100 away from the atomizing component 200. The airflow cavity 120 can be connected to the housing cavity 156 of the battery / electronic control component. The airflow in the airflow cavity 120 can also carry away the heat generated by the battery / electronic control component, thereby cooling the battery / electronic control component.

[0112] The technical solution provided in this application embodiment has at least a portion of the elastic limiting part 380 housed in the airflow cavity 120, which facilitates the contact between the first limiting surface 154 and the second limiting surface 381, resulting in more balanced force distribution. The elastic limiting part 380 is less likely to detach from the device body 100, and it also helps to reduce the volume of the airflow cavity 120, thereby optimizing the airflow distribution.

[0113] To facilitate the assembly of the first seal 300, refer to Figure 12 , Figure 13 and Figure 14 In some possible embodiments of this application, the device body 100 further includes a mounting groove 155 located on the side of the device body 100 near the atomizing component 200, and at least a portion of the first seal 300 is accommodated in the mounting groove 155.

[0114] In this embodiment, the mounting groove 155 can accommodate the third structural portion 390 of the first seal 300. In some examples, the contour of the mounting groove 155 is adapted to the contour of the third structural portion 390; in other words, the outer wall of the third structural portion 390 fits against the inner wall of the mounting groove 155. The third structural portion 390 may protrude or be recessed relative to the surface of the device body 100 near the atomizing component 200; or, the surface of the third structural portion 390 may be flush with the surface of the device body 100 near the atomizing component 200.

[0115] The technical solution provided in this application embodiment, by setting the mounting groove 155, facilitates the assembly of the first sealing member 300 and the device body 100, and facilitates mutual positioning between the two. On the other hand, the fact that at least a portion of the first sealing member 300 is accommodated in the mounting groove 155 also helps to reduce space occupation and facilitates the miniaturization of the device.

[0116] To improve the sealing effect, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 In some possible embodiments of this application, the first seal 300 includes a second structural portion 330 that extends into the second airflow channel 210 and fits against the peripheral inner wall of the second airflow channel 210.

[0117] In this embodiment, the second structural part 330 is attached to the inner peripheral wall of the second airflow channel 210, that is, the outer peripheral wall of the second structural part 330 and the inner peripheral wall of the second airflow channel 210 have similar structures and similar sizes, and can fit tightly together.

[0118] In this embodiment, an annular protrusion may be provided on at least one of the peripheral outer wall of the second structural part 330 and the peripheral inner wall of the second airflow channel 210 to further improve the sealing effect. The annular protrusion may be one or more, and multiple annular protrusions may be spaced apart axially along the third airflow channel 310.

[0119] It should be noted that the second structural portion 330 extends into the second airflow channel 210, and the opening of the third airflow channel 310 should also be provided in the second structural portion 330 so that the third airflow channel 310 is connected to the second airflow channel 210. For example, the airflow channel passes through the first structural portion 320 and the second structural portion 330 along the axial direction of the second airflow channel 210, and the inner contour of the airflow channel is similar to the outer contour of the second structural portion 330.

[0120] In some possible embodiments of this application, the second surface 220 of the atomizing component 200 is generally a flat surface, without any protruding structures, or with small protruding structures, to facilitate packaging and storage.

[0121] Reference Figure 1 In some possible embodiments of this application, the device body 100 has a receiving cavity 144, at least a portion of the atomizing component 200 extends into the receiving cavity 144, and the atomizing component 200 is detachably connected to the device body 100. The detachable connection between the atomizing component 200 and the device body 100 can be a snap-fit ​​connection, a threaded connection, a fastener connection, a magnetic connection, etc.

[0122] The technical solution provided in this application embodiment has at least a portion of the atomizing component 200 extending into the receiving cavity 144, which helps to improve space utilization. Furthermore, the atomizing component 200 is detachably connected to the device body 100, which facilitates the maintenance of the electronic atomizing device.

[0123] In some possible embodiments of this application, the device body 100 further includes a housing 140, which extends to form a receiving cavity 144. The atomizing component 200 extends into the receiving cavity 144 to connect with the device body 100. Optionally, the second structural part 330 is located in the receiving cavity 144, which does not easily affect the overall shape of the device body 100.

[0124] In some possible embodiments of this application, the atomizing component 200 is formed with an atomizing chamber 230 for mixing the atomized medium with air. A second protrusion 240 is provided in the atomizing chamber 230, and a second airflow channel 210 is opened in the second protrusion 240, that is, the first sealing member 300 is inserted into the second protrusion 240, and the second protrusion 240 protrudes relative to the bottom wall of the atomizing chamber 230, so that liquids such as condensate in the atomizing chamber 230 are not easily leaked through the air inlet of the second airflow channel 210.

[0125] The technical solution provided in this application embodiment extends the second structural part 330 into the second airflow channel 210 and makes the second structural part 330 fit against the peripheral inner wall of the second airflow channel 210. The two have a large contact area, thereby isolating the gap between the second airflow channel 210 and the device body 100 and the atomizing component 200, so as to provide good sealing performance.

[0126] To improve the connection stability between the atomizing component 200 and the device body 100, refer to Figure 1 , Figure 2 and Figure 3 In some possible embodiments of this application, the device body 100 forms a limiting structure 143, which is at least used to limit the radial movement of the atomizing component 200 relative to the device body 100 along the third airflow channel 310. The limiting structure 143 may form the aforementioned receiving cavity 144.

[0127] In this embodiment, the first sealing member 300 can also cooperate with the limiting structure 143 to limit the movement of the device body 100 and the atomizing component 200. Specifically, the first structural part 320 cooperates with the device body 100 to restrict the movement of the first sealing member 300 relative to the device body 100; the second structural part 330 cooperates with the atomizing component 200 to restrict the movement of the first sealing member 300 relative to the atomizing component 200. By using the first sealing member 300 as an intermediate bridge, the movement of the atomizing component 200 relative to the device body 100 can be restricted.

[0128] In this embodiment of the application, the structure of the first sealing member 300 for limiting may also include other structures provided on the first sealing member 300, such as the second sealing ring 370; or, for example, ribs or grooves provided on the surface of the first sealing member 300. The first sealing member 300 may include multiple identical or different structures for limiting.

[0129] In this embodiment, the first seal 300 can restrict the radial movement of the atomizing component 200 relative to the device body 100 along the third airflow channel 310; it can also limit the axial movement of the atomizing component 200 relative to the device body 100 along the third airflow channel 310. For example, the first structural part 320 is interference-fitted with the airflow cavity 120; the second structural part 330 is interference-fitted with the second airflow channel 210; or, the first seal 300 restricts the relative rotation of the atomizing component 200 and the device body 100 along the central axis of the third airflow channel 310. For example, both the first structural part 320 and the second structural part 330 are configured as square structures.

[0130] In this embodiment, the limiting structure 143 can be an annular limiting structure 143 provided on the device body 100, forming a receiving cavity 144. The atomizing component 200 can extend into the receiving cavity 144 to achieve assembly of the two. The inner peripheral wall of the limiting structure 143 and the outer peripheral wall of the atomizing component 200 can also be provided with locking structures such as snap-fits to improve the stability of the connection. It should be noted that the limiting structure 143 can also be provided on the atomizing component 200 to form the receiving cavity 144, and the device body 100 can extend into the receiving cavity 144 to form a mating structure. In one embodiment, the limiting structure 143 is part of the housing 140 of the device body 100.

[0131] The technical solution provided in this application embodiment allows the first sealing member 300 to cooperate with the limiting structure 143 of the device body 100 to at least restrict the relative movement of the atomizing component 200 and the device body 100 along the radial direction of the third airflow channel 310, thereby improving the connection stability of the atomizing component 200 and the device body 100.

[0132] To improve connection stability, refer to Figure 4 , Figure 9 and Figure 10 In some possible embodiments of this application, the device body 100 further includes a protrusion structure 151, which is disposed in the airflow cavity 120. The first sealing member 300 includes a relief groove 340 corresponding to the protrusion structure 151, which is sleeved on the protrusion structure 151.

[0133] In this embodiment, the protruding structure 151 of the device body 100 can be a reinforcing structure, such as a reinforcing rib or reinforcing brace. The protruding structure 151 can also be a connecting structure, such as a positioning post or positioning protrusion. For example, the protruding structure 151 is a mounting structure for mounting the conductive component 130; or, for another example, the protruding structure 151 is a first protrusion 153 providing the sensing channel 152. It should be noted that the clearance groove 340 also corresponds to an airflow channel to facilitate airflow.

[0134] In this embodiment, the clearance groove 340 is sleeved on the protrusion structure 151. The two can be spaced apart to facilitate assembly; they can also be fitted together to improve the connection stability of the first seal 300 and serve as a first limiting structure to restrict the movement of the atomizing component 200 relative to the device body 100.

[0135] In this embodiment, the clearance groove 340 corresponds to the position of the protrusion 151. The clearance groove 340 can be disposed on the peripheral outer wall of the first structural portion 320, or it can be disposed on the side of the first structural portion 320 away from the atomizing component 200. For example, the side of the first structural portion 320 away from the atomizing component 200 is provided with a clearance groove 340 corresponding to the conductive member 130 and a clearance groove 340 corresponding to the first protrusion 153.

[0136] The technical solution provided in this application embodiment includes a protruding structure 151 disposed in the airflow cavity 120. The first sealing member 300 is provided with an avoidance groove 340 corresponding to the protruding structure 151. On the one hand, it can avoid the protruding structure 151. On the other hand, the avoidance groove 340 is sleeved on the protruding structure 151, and the two can limit each other to improve the connection stability between the first sealing member 300 and the device body 100.

[0137] To improve connection stability, refer to Figure 12 and Figure 14 In some possible embodiments of this application, the device body 100 includes a mounting groove 155, at least a portion of the first seal 300 is accommodated in the mounting groove 155, and the device body 100 also includes a protrusion structure 151 disposed in the mounting groove 155, and the first seal 300 is provided with an avoidance groove 340 corresponding to the protrusion structure 151.

[0138] In this embodiment, the outlines of the mounting groove 155 and the third structural portion 390 can be regular or irregular shapes such as circles, squares, and ellipses. For example, the outline of the third structural portion 390 is approximately rectangular, with chamfered corners. The two ends of the third structural portion 390 along the length direction have concave arc-shaped structures, thereby forming clearance grooves 340 at both ends of the third structural portion 390 along the length direction. The clearance grooves 340 are used to avoid the protruding structure 151 of the device body 100.

[0139] In this embodiment of the application, the protruding structure 151 of the device body 100 can be used as a limit, and the protruding structure 151 can also be used to enhance the structural strength, such as a rib. The protruding structure 151 can also be formed by the device body 100 to avoid other components. For example, an atomizing component 200 is installed in the device body 100, and the device body 100 forms a protruding structure 151 to avoid the atomizing component 200.

[0140] The technical solution provided in this application embodiment includes a device body 100 with a protruding structure 151 disposed in the mounting groove 155. The first sealing member 300 is provided with a relief groove 340 corresponding to the protruding structure 151 in the mounting groove 155. On the one hand, it can avoid the protruding structure 151. On the other hand, the relief groove 340 and the protruding structure 151 can limit each other to improve the connection stability between the first sealing member 300 and the device body 100.

[0141] To improve the stability of the connection between the device body 100 and the atomizing component 200, refer to Figure 1 and Figure 10 In some possible embodiments of this application, the electronic atomizing device further includes a magnetic structure 600, which is disposed between the device body 100 and the atomizing component 200. The first sealing member 300 cooperates with the magnetic structure 600 to fix the atomizing component 200 and the device body 100 relative to each other.

[0142] In this embodiment, the magnetic structure 600 may include a magnetic attraction part, which can magnetically attract magnetic components. For example, the device body 100 and the atomizing component 200 are respectively provided with magnetic attraction parts, and the two magnetic attraction parts have opposite polarities, so that the device body 100 and the atomizing component 200 can be magnetically attracted and fixed by the magnetic attraction parts. Alternatively, one of the device body 100 and the atomizing component 200 is provided with a magnetic attraction part, and the other is provided with a magnetic component containing magnetic materials such as iron and nickel (e.g., the outer shell of the atomizing component 200). The magnetic attraction part attracts the magnetic component, thereby magnetically fixing the device body 100 and the atomizing component 200.

[0143] In this embodiment, the first sealing member 300 can be used in conjunction with the magnetic attraction structure 600 to limit the movement of the atomizing component 200 relative to the device body 100 along the third airflow channel 310. The first sealing member 300 restricts the radial movement of the atomizing component 200 relative to the device body 100 along the third airflow channel 310 through the first structural part 320 and the second structural part 330, so as to limit the shaking of the atomizing component 200 relative to the device body 100.

[0144] In this embodiment, the magnetic attraction structure 600, the limiting structure 153, and the first sealing member 300 can be combined to work together to limit the atomizing component 200 relative to the device body 100, reduce shaking, and improve connection stability.

[0145] The technical solution provided in this application embodiment provides effective limiting for the atomizing component 200 and the device body 100 by setting up a magnetic attraction structure 600, and the combination of the first sealing member 300 and the magnetic attraction structure 600, thereby improving the connection stability of the atomizing component 200 and the device body 100.

[0146] To facilitate the assembly of the first seal 300 and improve connection stability, refer to Figure 4 , Figure 6 ,and Figure 8 In some possible embodiments of this application, the device body 100 further includes a conductive element 130, and the first sealing element 300 has a through hole 350 through which the conductive element 130 passes to connect to the atomizing assembly 200.

[0147] In this embodiment, the conductive element 130 can be an elastic electric needle that supplies power from the device body 100 to the atomizing component 200. The peripheral outer wall of the conductive element 130 and the peripheral inner wall of the through hole 350 can be spaced apart to facilitate assembly; they can also be fitted together to improve the connection stability of the first sealing element 300, and serve as a first limiting structure to restrict the movement of the atomizing component 200 relative to the device body 100.

[0148] In this embodiment, multiple conductive elements 130 may be provided, and the first sealing element 300 is provided with a through hole 350 for each conductive element. The multiple through holes 350 can be evenly distributed. For example, the first sealing element 300 is provided with two through holes 350, and the two through holes 350 are symmetrically distributed on both sides of the third airflow channel 310 along the length direction of the first structural part 320.

[0149] The technical solution provided in this application embodiment includes a through hole 350 in the first sealing member 300, which facilitates the conductive member 130 to pass through the through hole 350 and connect to the atomizing assembly 200. Furthermore, the conductive member 130 can serve as a positioning or guiding component to facilitate the assembly of the first sealing member 300 with the device body 100. The conductive member 130 and the through hole 350 can cooperate to form a limiting mechanism, thereby improving the connection stability between the first sealing member 300 and the device body 100.

[0150] To improve sealing performance, refer to Figure 6 and Figure 8 In some possible embodiments of this application, the first seal 300 further includes a first sealing ring 360, which surrounds the through hole 350 and abuts against the atomizing assembly 200, for example, the first sealing ring 360 abuts against the second surface 220.

[0151] In this embodiment, the through hole 350 can be formed in the first structural portion 320, and the first sealing ring 360 is also a protruding portion of the first structural portion 320 facing the second surface 220. The outline of the first sealing ring 360 and the outline of the through hole 350 can be the same or different. For example, the outline of the first sealing ring 360 and the radial outline of the through hole 350 are both circular.

[0152] In this embodiment, the first sealing ring 360 can be made of an elastic material similar to the second sealing ring 370. When the atomizing component 200 is assembled to the device body 100, the first sealing ring 360 elastically deforms to tightly fit the second surface 220. In addition, each through hole 350 may correspond to multiple first sealing rings 360, and the multiple first sealing rings 360 have different sizes to form a nested structure to further improve the sealing performance.

[0153] Understandably, the tight fit between the first sealing ring 360 and the atomizing component 200 can provide a good airtight seal to ensure stable airflow. On the other hand, it can also provide functions such as dust prevention, leakage prevention, and sound insulation. For example, it can prevent the atomizing medium of the atomizing component 200 from flowing into the device body 100 through the hole 350, thereby protecting the power supply components, control components, etc. in the device body 100.

[0154] The technical solution provided in this application embodiment includes a first sealing ring 360 on the first sealing member 300. The first sealing ring 360 surrounds the periphery of the through hole 350 and abuts against the atomizing component 200, thereby isolating the gap between the through hole 350 and the device body 100 and the atomizing component 200 to improve the sealing performance.

[0155] To improve sealing performance, refer to Figure 12In some possible embodiments of this application, the first seal 300 further includes a first sealing ring 360, which abuts against the atomizing assembly 200. The through hole 350 and the third airflow channel 310 are both located inside the first sealing ring 360.

[0156] In this embodiment, the first sealing ring 360 is an annular structure surrounding the through hole 350 and the third airflow channel 310. The first sealing ring 360 can be a regular or irregular shape such as a circle, square, or ellipse.

[0157] The technical solution provided in this application embodiment, by setting a first sealing ring 360, with the through hole 350 and the third airflow channel 310 all located inside the first sealing ring 360, achieves isolation of multiple holes or channels with a single first sealing ring 360, which is simple in structure and easy to implement.

[0158] To facilitate triggering the airflow sensor 400, refer to Figure 5 In some possible embodiments of this application, the device body 100 is further provided with a sensing channel 152, which is connected to the airflow cavity 120 and is connected to the airflow sensor 400; a first protrusion 153 is provided in the airflow cavity 120, which protrudes relative to the bottom wall of the airflow cavity 120, and the opening of the sensing channel 152 is provided in the first protrusion 153.

[0159] In this embodiment, the sensing channel 152 is connected to the airflow cavity 120. The opening of the sensing channel 152 can be disposed on the inner wall of the peripheral side of the airflow cavity 120 or on the first protrusion 153. The opening of the sensing channel 152 can be disposed in the middle or at the edge of the airflow cavity 120. For example, the opening of the sensing channel 152 is disposed on the side of the first protrusion 153 near the first surface 110. In other words, the opening of the sensing channel 152 is located on the top surface of the first protrusion 153 relative to the airflow cavity 120.

[0160] In this embodiment, the airflow sensor 400 can be used as the start-up sensor of the electronic atomization device. That is, the airflow sensor 400 is used to detect the air pressure of the airflow chamber 120. When the negative pressure of the airflow chamber 120 reaches the preset pressure, the airflow sensor 400 is triggered, and the controller provides power to the atomization component 200 based on the triggering control of the airflow sensor 400.

[0161] The technical solution provided in this application embodiment, by setting a first protrusion 153, sets the opening of the sensing channel 152 on the first protrusion 153, so that the opening of the sensing channel 152 is higher than the bottom wall of the airflow cavity 120. On the one hand, the opening of the sensing channel 152 is closer to the inlet of the second airflow channel 210, making the airflow sensor 400 more sensitive. On the other hand, it can prevent the liquid (such as e-liquid) in the airflow cavity 120 from flowing into the sensing channel 152, so as to protect the airflow sensor 400.

[0162] To improve sensing sensitivity, refer to Figure 17 In some possible embodiments of this application, the first airflow channel 160 includes an airflow cavity 120, the device body 100 forms a receiving cavity 156 for receiving a battery and / or electronic control components, and the receiving cavity 156 is connected to the airflow cavity 120; the device body 100 also has a sensing channel 152, the sensing channel 152 is connected to an airflow sensor 400, and the sensing channel 152 is connected to the receiving cavity 156.

[0163] In this embodiment, the accommodating cavity 156 may be disposed in the part of the device body 100 away from the atomizing component 200. The accommodating cavity 156 may be formed by the bracket 150, or the accommodating cavity 156 may be formed by the bracket 150 and the housing 140.

[0164] In some examples, the accommodating cavity 156 is located between the airflow cavity 120 and the sensing channel 152. For example, the airflow cavity 120 is provided at one end of the accommodating cavity 156 near the atomizing assembly 200, and the sensing channel 152 is provided at the other end of the accommodating cavity 156 away from the atomizing assembly 200.

[0165] In the technical solution provided in this application embodiment, the airflow cavity 120 and the sensing channel 152 are connected through the accommodating cavity 156. The airflow in the airflow cavity 120 will drive the airflow in the accommodating cavity 156, thereby forming an airflow that can cool the battery and / or electronic control components in the accommodating cavity 156.

[0166] To improve sealing performance, refer to Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11 In some possible embodiments of this application, the device body 100 includes a housing 140 and a support 150, the support 150 being housed within the housing 140, the first airflow channel 160 including a channel segment 163 formed by the housing 140 and the support 150, and the electronic atomizing device further includes a second seal 500, the second seal 500 being sealed between the support 150 and the housing 140, and the second seal 500 being located on the side of the channel segment 163 near the atomizing assembly 200.

[0167] In this embodiment, the housing 140 of the device body 100 is used to accommodate the bracket 150, the first seal 300, the power supply component, the electronic control component, etc., to provide protection. The housing 140 may include a first outer peripheral surface 141, a second outer peripheral surface 142, a limiting structure 143, etc.

[0168] In this embodiment, the bracket 150 can be a battery bracket 150 of a power supply component, a circuit board bracket 150 of an electronic control component, etc. The bracket 150 may include a protruding structure 151, a sensing channel 152, etc.; the airflow cavity 120 may be formed on the bracket 150, and the first opening 161 passes through the bracket 150 and communicates with the airflow cavity 120; the first surface 110 may also be the side of the bracket 150 facing the atomizing component 200.

[0169] In this embodiment, the channel segment 163 may include a groove formed on the outer periphery of the bracket 150. The groove and the inner periphery of the housing 140 enclose the channel segment 163. Since there may be a gap between the outer periphery of the bracket 150 and the inner periphery of the housing 140, air leakage may occur. Providing a second sealing element 500 can alleviate this problem.

[0170] In this embodiment, the second sealing member 500 can be an annular structure surrounding the bracket 150. A receiving groove is formed on the outer peripheral wall of the bracket 150. The second sealing member 500 is disposed within the receiving groove and conforms to the inner wall of the receiving groove, thus limiting the position of the second sealing member 500. The other side of the second sealing member 500 conforms to the inner peripheral wall of the housing 140. An elastic annular protrusion can also be provided between the second sealing member 500 and the housing 140 to further enhance the sealing effect. There can be one or more annular protrusions, and multiple annular protrusions are spaced apart along the axial direction of the device body 100.

[0171] It should be noted that the second seal 500 and the first seal 300 can also be integrated into a single structure and fitted onto the end of the bracket 150 to provide a more comprehensive sealing effect.

[0172] The technical solution provided in this application embodiment provides a good sealing performance by setting a second sealing element 500 between the housing 140 and the bracket 150. The second sealing element 500 is located on the side of the channel section 163 near the atomizing component 200, thereby isolating the gap between the channel section 163 and the device body 100 and the atomizing component 200.

[0173] To improve sealing performance, refer to Figure 17In some possible embodiments of this application, the electronic atomizing device further includes a third seal 700, which is sealed between the bracket 150 and the housing 140, and the third seal 700 is located on the side of the channel segment 163 away from the atomizing assembly 200.

[0174] In this embodiment, the third seal 700 can be an annular structure surrounding the bracket 150. The outer peripheral wall of the bracket 150 is provided with a receiving groove. The third seal 700 is disposed in the receiving groove and fits against the inner wall of the receiving groove. The receiving groove can limit the third seal 700. The other side of the third seal 700 fits against the inner peripheral wall of the housing 140.

[0175] In this embodiment, an elastic annular protrusion may be provided between the third seal 700 and the housing 140 to further improve the sealing effect. The annular protrusion may be one or more, and multiple annular protrusions may be spaced apart along the axial direction of the device body 100.

[0176] The technical solution provided in this application embodiment provides good sealing performance by setting a third seal 700 between the housing 140 and the bracket 150. The third seal 700 is located on the side of the channel segment 163 away from the atomizing component 200, thereby isolating the channel segment 163 relative to other gaps between the bracket 150 and the housing 140.

[0177] To improve the user experience, refer to Figure 10 and Figure 11 In some possible embodiments of this application, the channel segment 163 surrounds the bracket 150 circumferentially. The channel segment 163 includes a first opening 161 opened in the bracket 150 and a second opening 162 opened in the housing 140. The first opening 161 and the second opening 162 are spaced apart circumferentially from the bracket 150.

[0178] In this embodiment, channel segment 163 can serve as the air intake channel of the electronic atomizing device. When the user acts on the second airflow channel 210, the external airflow can flow in through the second opening 162 of channel segment 163, and then flow into the airflow chamber 120 through the first opening 161, and then flow to the second airflow channel 210 through the third airflow channel 310, thereby forming a negative pressure in the airflow chamber 120.

[0179] The technical solution provided in this application embodiment has a channel segment 163 surrounding the circumference of the bracket 150. On the one hand, this facilitates the processing of the channel segment 163. On the other hand, since the first opening 161 and the second opening 162 are spaced apart along the circumference of the bracket 150, and there is a long distance between them, the outflow of condensate and other liquids in the channel segment 163 can be reduced (i.e., condensate is prevented from flowing out of the second opening 162 to the outside of the housing 140), thereby improving the user experience.

[0180] Furthermore, the channel segment 163 is located on the periphery of the bracket 150, which can also prevent airflow from passing through the power supply components (such as batteries), thereby protecting the power supply components and improving safety. It should be noted that the second opening 162 can be located on the periphery surface of the housing 140, or it can be located on the bottom surface of the housing 140 (the side surface away from the atomizing component 200).

[0181] To facilitate airflow control, refer to Figure 10 and Figure 11 In some possible embodiments of this application, the first opening 161 of the channel segment 163 is disposed on the inner wall of the airflow cavity 120; the device body 100 includes a first outer peripheral surface 141 and a second outer peripheral surface 142, the size of the first outer peripheral surface 141 is smaller than the size of the second outer peripheral surface 142, and the second opening 162 of the channel segment 163 is disposed on the first outer peripheral surface 141.

[0182] In this embodiment, the first outer peripheral surface 141 and the second outer peripheral surface 142 are peripheral surfaces of the device body 100, which can be used for user gripping. For example, the device body 100 includes two opposing first outer peripheral surfaces 141 and two opposing second outer peripheral surfaces 142, which together enclose and form the peripheral outer wall of the device body 100.

[0183] In this embodiment, the size of the first outer peripheral surface 141 is smaller than the size of the second outer peripheral surface 142. Specifically, the area of ​​the first outer peripheral surface 141 is smaller than the area of ​​the second outer peripheral surface 142. It can be understood that when the lengths of the first outer peripheral surface 141 and the second outer peripheral surface 142 along the axial direction of the device body 100 are similar, the size of the first outer peripheral surface 141 along the circumferential direction of the device body 100 is smaller than the size of the second outer peripheral surface 142 along the circumferential direction of the device body 100. That is, the first outer peripheral surface 141 is the narrow side surface of the device body 100, and the second outer peripheral surface 142 is the wide side surface of the device body 100.

[0184] In this embodiment, the channel segment 163 can be disposed on one side of the bracket 150 or it can be a ring structure surrounding the bracket 150. One or more first openings 161 and one or more second openings 162 can be disposed along the line of the channel segment 163. Multiple second openings 162 can reduce the possibility of users holding and blocking the air, while multiple first openings 161 facilitate stable airflow distribution. In addition, the first openings 161 also have a gas-saving function.

[0185] The technical solution provided in this application embodiment includes a first airflow channel 160 in the device body 100, which communicates with the outside. Due to the presence of the first sealing member 300, the gap between the first surface 110 and the second surface 220 is blocked. Airflow must pass through the first airflow channel 160 to the second airflow channel 210. The first airflow channel 160 can be designed according to requirements to facilitate airflow control and provide stable air pressure. In addition, the second opening 162 is located on the first surface, which not only improves the structural aesthetics but also prevents it from being blocked by the user's grip.

[0186] To improve sealing performance, refer to Figure 12 , Figure 13 and Figure 15 In some possible embodiments of this application, the first airflow channel 160 includes an airflow cavity 120 and a second opening 162. The second opening 162 is disposed in the housing 140. At least one side of the airflow cavity 120 passes through the bracket 150 and extends to the housing 140. The second opening 162 is connected to the airflow cavity 120 through at least one channel segment 163.

[0187] In this embodiment, at least one side of the airflow cavity 120 passes through the support 150. In other words, the support 150 is provided with a channel on the corresponding side of the airflow cavity 120, or the support 150 is not provided with a solid structure on the corresponding side of the airflow cavity 120, and the corresponding side wall of the airflow cavity 120 is defined by the inner wall of the housing 140.

[0188] In this embodiment of the application, the airflow cavity 120 may pass through the support 150 on one or more sides. For example, the airflow cavity 120 passes through the support 150 on both sides parallel to its length direction, and the airflow cavity 120 is provided with protrusions 156 and second openings 162 on both sides parallel to its width direction.

[0189] In this embodiment of the application, the second opening 162 can be connected to the airflow cavity 120 through one or more channel segments 163. For example, each second opening 162 is connected to two channel segments 163, and the two channel segments 163 are respectively connected to the two ends of the corresponding through hole 1521.

[0190] The technical solution provided in this application embodiment is that the airflow cavity 120 passes through the support 150, which facilitates the communication between the airflow cavity 120 and the second opening 162. The second opening 162 can be connected to the airflow cavity 120 through one or more channel segments 163, which facilitates the flow of airflow between the second opening 162 and the airflow cavity 120.

[0191] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 In one possible embodiment of this application, the electronic atomizing device includes a device body 100 and an atomizing component 200. The device body 100 includes a housing 140 and a support 150. The support 150 is housed within the housing 140 and is used to support a battery, electronic control components, etc. The support 150 includes a first surface 110. The housing 140 extends beyond the first surface 110 to form a limiting structure 143. The atomizing component 200 can be inserted into the limiting structure 143 to connect to the device body 100, and the second surface 220 of the atomizing component 200 is opposite to the first surface 110.

[0192] The first airflow channel 160 includes an airflow cavity 120 formed on the first surface 110. The airflow cavity 120 is connected to the airflow sensor 400 through the sensing channel 152. The airflow cavity 120 is used as a negative pressure sensing cavity. The atomizing assembly 200 is provided with a second airflow channel 210.

The channel segment 163 is connected to the airflow cavity 120, and the airflow cavity 120 is connected to the second airflow channel 210.

[0193] Based on this, the electronic atomizing device is further provided with a first seal 300 and a second seal 500. The second seal 500 is disposed between the bracket 150 and the housing 140, and is located on the side of the channel section 163 near the atomizing assembly 200, to isolate the gap between the first airflow channel 160 and the first surface 110 and the second surface 220. The first seal 300 is disposed between the atomizing assembly 200 and the bracket 150, and is used to connect the second airflow channel 210 and the airflow chamber 120 through the third airflow channel 310, and to isolate the gap between the second airflow channel 210 and the airflow chamber 120 and the first surface 110 and the second surface 220.

[0194] Specifically, the first sealing element 300 includes a first structural portion 320 and a second structural portion 330. The first structural portion 320 extends into the airflow cavity 120 and seals with it. The second structural portion 330 extends into the second airflow channel 210 and seals with it. The first structural portion 320 has a through hole 350 and a clearance groove 340 to allow the conductive element 130 of the device body 100 to pass through the first sealing element 300 and connect to the atomizing assembly 200. The first sealing element 300 also includes a second sealing ring 370 disposed on the outer wall of the periphery of the first structural portion 320, and a first sealing ring 360 disposed around the through hole 350 to further improve the sealing effect.

[0195] Reference Figure 1 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 In another possible embodiment of this application, the electronic atomizing device includes a device body 100 and an atomizing component 200. The device body 100 includes a housing 140 and a support 150. The support 150 is housed within the housing 140 and is used to support a battery, electronic control components, etc. The support 150 includes a first surface 110. The housing 140 extends beyond the first surface 110 to form a limiting structure 143. The atomizing component 200 can be inserted into the limiting structure 143 to connect to the device body 100, and the second surface 220 of the atomizing component 200 is opposite to the first surface 110.

[0196] The first airflow channel 160 includes an airflow cavity 120, which is located on the side of the bracket 150 opposite to the first surface 110. The airflow cavity 120, the bracket 150, and the housing 140 also enclose a receiving cavity 156, in which the battery / electronic control assembly is located. A sensing channel 152 is provided at the end of the receiving cavity 156 away from the airflow cavity 120, and is connected to the airflow sensor 400 via the sensing channel 152. The airflow cavity 120 serves as a negative pressure sensing cavity. The first airflow channel 160 also includes a second opening 162, each of which is connected to the airflow cavity 120 via two channel segments 163. The atomizing assembly 200 has a second airflow channel 210, which is connected to the airflow cavity 120 via a first sealing member 300.

[0197] Based on this, the electronic atomizing device is further provided with a first seal 300, a second seal 500, and a third seal 700. The second seal 500 and the third seal 700 are disposed between the bracket 150 and the housing 140, respectively located on both sides of the first airflow channel 160, to isolate the gap between the first airflow channel 160 and the first surface 110 and the second surface 220, and the gap between the first airflow channel 160 and the bracket 150 and the housing 140. The first seal 300 is disposed between the atomizing assembly 200 and the bracket 150, and is used to connect the second airflow channel 210 and the airflow chamber 120 through the third airflow channel 310, and to isolate the gap between the second airflow channel 210 and the airflow chamber 120 and the first surface 110 and the second surface 220.

[0198] Specifically, the first sealing element 300 includes a third structural part 390 and a second structural part 330. The third structural part 390 is located in the mounting groove 155 and is sealed to the mounting groove 155. The second structural part 330 extends into the second airflow channel 210 and is sealed to the second airflow channel 210.

A first limiting surface 154 is formed on the side of the bracket 150 away from the first surface 110. The first limiting surface 154 abuts against the second limiting surface 381. The second limiting surface 381 is formed by a flange structure 382. The radial dimension of the flange structure 382 gradually decreases in the direction away from the third structural portion 390. An extension structure 383 is also provided at the end of the flange structure 382 away from the third structural portion 390. The end of the extension structure 383 is hemispherical.

[0200] During use, the user applies negative pressure to the second airflow channel 210, causing airflow to flow in from the channel section 163, enter the airflow chamber 120 to act on the airflow sensor 400, and then flow back into the second airflow channel 210 to fuse with the atomizing medium to form an aerosol for the user. Due to the first sealing element 300, the airflow path is isolated relative to the gap between the first surface 110 and the second surface 220, thus controlling the overall airflow. This facilitates the formation of a stable and uniform negative pressure, making it easier to start the electronic atomizing device, while also reducing noise, providing stable limiting, and preventing the atomizing medium from entering the device body 100.
