Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular provides an outer cover component and an atomization device. Background Art

[0002] Traditional electronic atomizers do not have any protective measures for the lip contact part (mouthpiece). After using the electronic atomizer, consumers tend to put the electronic atomizer on the table, pocket or other places, which causes the mouthpiece to be directly exposed to the air and easily contaminated, resulting in bacteria or dust covering the mouthpiece of the atomizer, which affects the health of consumers. In addition, if consumers do not use the electronic atomizer for a long time, the atomizer liquid in the electronic atomizer will be connected and in contact with the outside air for a long time, which can easily cause the taste to decay and affect the user experience. Utility Model Content

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] The embodiment of the present application provides an outer cover component, which is used to cover an atomizing device; the outer cover component includes: a rotating sleeve, a top cover, a base and a rotating telescopic structure, the rotating sleeve is sleeved on the atomizing device, and the atomizing device has a suction nozzle; the rotating sleeve has a first end close to the suction nozzle and a second end away from the first end, and the rotating sleeve is formed with a avoidance opening at the first end; the top cover is movably arranged at the first end of the rotating sleeve and is used to open or cover the avoidance opening; the base is sleeved on the rotating sleeve by the second end, and the base and the rotating sleeve are rotatably matched; the rotating telescopic structure includes an adjusting member, an arc groove provided on the rotating sleeve, and a linear groove provided on the inner wall of the base and extending along a first direction, and the first direction is parallel to the axial direction of the rotating sleeve; the adjusting member is simultaneously inserted in the arc groove and the linear groove and is used to connect with the atomizing device; the rotating sleeve rotates relative to the base to drive the adjusting member to move in the arc groove, and the adjusting member moves along the linear groove at the same time.

[0006] The beneficial effect of the outer cover assembly of the present application lies in that the adjusting member is used to cooperate with the arc groove and the straight groove at the same time, and then the rotational motion of the rotating sleeve is converted into the straight motion of the atomizing device; when the atomizing device needs to be used, the rotating sleeve is controlled to rotate relative to the base, and the arc groove cooperates with the adjusting member to make the adjusting member move in the straight groove of the base along the first direction, thereby driving the atomizing device to move along the first direction; the top cover is controlled to open the avoidance port, and the atomizing device passes through the avoidance port and protrudes outside the rotating sleeve, so that the user can inhale and use the atomizing device; when the atomizing device is not needed, the rotating sleeve is controlled to rotate in the opposite direction, so that the atomizing device can be reset and moved to be retracted in the rotating sleeve again, and the top cover is controlled to close the avoidance port, so that the suction nozzle is isolated from the external air, thereby effectively protecting the atomizing device.

[0007] In some embodiments, the outer cover assembly also includes a rotation limiting structure, which includes a limiting ring groove provided on one of the base and the rotating sleeve, and a limiting block provided on the other of the base and the rotating sleeve; the limiting block can move along the limiting ring groove in a first plane, and the first plane is perpendicular to the first direction; the movement stroke of the limiting block in the limiting ring groove is the rotation stroke between the rotating sleeve and the base.

[0008] By adopting the above technical solution, the rotating sleeve can stably rotate relative to the base through the cooperation between the limiting block and the limiting ring groove, and the rotating sleeve can only rotate within a certain angle, which limits the excessive rotation of the rotating sleeve and improves the rotation stability.

[0013] In some embodiments, the base further includes at least two spaced-apart ridges provided on the inner wall surface of the bottom sleeve, and the ridges extend along the first direction; the adjacent two ridges and the inner wall surface of the bottom sleeve enclose to form the linear groove.

[0014] By adopting the above technical solution, the regulating member can be effectively restricted within the linear groove by forming the linear groove with the ridges on the inner wall of the bottom sleeve; no groove structure is formed on the outer wall surface of the bottom sleeve, making the outer wall surface of the outer cover assembly flat.

[0015] In some embodiments, the arc-shaped groove includes a proximal end and a distal end that are opposite to each other, and the proximal end is closer to the first end in the first direction relative to the distal end; during the process that the regulating member moves from the distal end to the proximal end, the suction nozzle portion extends out of the rotary sleeve from the rotary sleeve.

[0016] By adopting the above technical solution, the regulating member moves within the arc-shaped groove, and the regulating member will displace relative to the rotary sleeve in the first direction, so that the atomizing device moves relative to the rotary sleeve in the first direction.

[0017] In some embodiments, the outer cover assembly includes at least two groups of the rotary telescopic structures circumferentially spaced apart around the first direction; each group of the rotary telescopic structures includes a regulating member, an arc-shaped groove and a linear groove that cooperate with each other; and the arc-shaped grooves are distributed in a circumferential array on the rotary sleeve.

[0049] For traditional e-cigarette devices, there are no protective measures for the lip contact part (mouthpiece). After consumers use the e-cigarette device, they habitually put the e-cigarette device on the table, in the pocket or other places casually; as a result, the mouthpiece is directly exposed to the air and is easily contaminated, causing bacteria or dust to cover the mouthpiece part of the atomization device, which has an impact on the health of consumers. In addition, if consumers do not use the e-cigarette device for a long time, the atomization liquid in the e-cigarette device is in direct contact with the external air for a long time, which is likely to cause attenuation of the taste and affect the use experience.

[0050] Based on this, in order to solve the above problems, this application designs a cover assembly for covering the outside of the atomization device; by using the adjusting member to cooperate with the arc-shaped groove and the straight groove at the same time, and then converting the rotational movement of the rotating sleeve into the linear movement of the atomization device; when the atomization device needs to be used, control the rotating sleeve to rotate relative to the base, and the arc-shaped groove cooperates with the adjusting member to make the adjusting member move in the straight groove of the base along the first direction, so as to drive the atomization device to move along the first direction; control the top cover to open the avoidance port, and the atomization device passes through the avoidance port and protrudes outside the rotating sleeve to meet the user's suction use of the atomization device; when the rotating sleeve rotates in the reverse direction, the atomization device can be reset and moved to shrink into the rotating sleeve again, and control the top cover to close the avoidance port to isolate the mouthpiece part from the external air, forming an effective protection for the atomization device.

[0051] Refer to Figure 1, Figure 2 , Figure 3 An embodiment of the present application provides an atomization device, including an atomization device 200 and an outer cover assembly 100 for covering the outside of the atomization device 200.

[0052] Specifically, the atomizing device 200 is a device for atomizing a liquid aerosol matrix to generate atomized gas. The atomizing device 200 has a mouthpiece 2001 , and a user inhales the atomized gas by inhaling the mouthpiece 2001 .

[0053] Please refer to Figure 3 , Figure 4 , Figure 5 In some embodiments, the outer cover assembly 100 includes a rotating sleeve 1, a top cover 2, a base 3 and a rotating telescopic structure 4; the rotating sleeve 1 is sleeved on the atomizing device 200, and the atomizing device 200 has a nozzle 2001; the rotating sleeve 1 has a first end 101 close to the nozzle 2001 and a second end 102 away from the first end 101, and the rotating sleeve 1 is formed with an avoidance opening 103 at the first end 101; the top cover 2 is movably arranged at the first end of the rotating sleeve 1 and is used to open or cover the avoidance opening 103; the base 3 is sleeved on the rotating sleeve 1 from the second end 102, and The base 3 is rotatably matched with the rotating sleeve 1; the rotating telescopic structure 4 includes an adjusting member 7, an arcuate groove 5 provided on the rotating sleeve 1, and a linear groove 6 provided on the inner wall of the base 3 and extending along a first direction X, wherein the first direction X is parallel to the axial direction of the rotating sleeve 1; the adjusting member 7 is simultaneously penetrated in the arcuate groove 5 and the linear groove 9 and is used to be connected with the atomizing device 200; the rotating sleeve 1 rotates relative to the base 3 to drive the adjusting member 7 to move in the arcuate groove 5, and the adjusting member 7 simultaneously moves along the linear groove 6 and drives the atomizing device 200 to move in the first direction X.

[0054] The first direction X in the embodiment of the present application is the axial direction of the rotating sleeve 1, which is the X direction shown in the figure. The adjusting member 7 drives the atomizing device 200 to reciprocate along the first direction X relative to the rotating sleeve 1 so that the suction nozzle 2001 extends out of the rotating sleeve 1 or retracts into the rotating sleeve 1.

[0055] During the process of the user rotating the rotating sleeve 1 relative to the base 3, the adjusting member 7 is utilized to cooperate with the arc-shaped groove 5 and the linear groove 6 simultaneously, and then the rotational motion is converted into linear motion. Specifically, when the rotating sleeve 1 rotates, the arc-shaped groove 5 rotates and moves around the atomizing device 200. The inner wall of the arc-shaped groove 5 will exert a force on the adjusting member 7 in the first direction X and a force perpendicular to the first direction X; while the linear groove 6 can limit the displacement of the adjusting member 7 in the direction perpendicular to the first direction X; then the adjusting member 7 will move along the linear groove 6 in the first direction X under the action of the force, thereby driving the atomizing device 200 to move in the first direction X. By controlling the clockwise or counterclockwise movement of the rotating sleeve 1 relative to the base 3, the atomizing device 200 can be driven to perform telescopic motion in the first direction X, so that the nozzle portion 2001 extends out of the rotating sleeve 1 or contracts into the rotating sleeve 1. The adjusting member 7 can specifically be a cylindrical body, a sleeve body or other structures.

[0056] It can be understood that the arc-shaped groove 5 can be a short groove, that is, the arc-shaped groove 5 is formed at a partial position of the rotating sleeve 1; the arc-shaped groove 5 can also be a spiral groove surrounding the rotating sleeve 1; as long as the movement stroke of the adjusting member 7 in the arc-shaped groove 5 is sufficient to drive the nozzle portion 2001 of the atomizing device 200 to extend from the inside of the rotating sleeve 1 to the outside.

[0057] The structural shape of the top cover 2 is not limited herein, as long as the top cover 2 can open or cover the avoidance opening 103. For example, the top cover 2 can be a cover plate structure, and the top cover 2 is hinged to the first end 101 of the rotating sleeve 1, and the top cover 2 is flipped to open or cover the avoidance opening 103; alternatively, the top cover 2 can be a sleeve structure, and the top cover 2 is detachably sleeved on the first end 101 of the rotating sleeve 1.

[0058] The specific assembly steps of the outer cover assembly 100 and the atomizing device 200 are as follows: First, the rotating sleeve 1 is sleeved outside the atomizing device 200, then the adjusting member 7 is passed through the arc-shaped groove 5 from outside the rotating sleeve 1 and connected and fixed to the outer wall of the atomizing device 200; finally, the base 3 is sleeved on the rotating sleeve 1 and the adjusting member 7 is passed through the linear groove 6. It can be understood that the adjusting member 7 is initially separated from the atomizing device 200, and the adjusting member 7 can be arranged on the outer wall of the atomizing device 200 by but not limited to riveting, welding, plugging, bonding and other methods, so as to ensure that the adjusting member 7 and the atomizing device 200 move synchronously in the first direction X.

[0059] In some embodiments, an installation positioning hole (not shown) for connecting with the adjusting member 7 is provided on the outer wall of the atomizing device 200; the adjusting member 7 can be installed in the installation positioning hole by but not limited to threaded connection, riveting and other methods.

[0060] The outer cover assembly 100 of the present application utilizes the adjusting member 7 to cooperate with the arc-shaped groove 5 and the linear groove 6 at the same time, and then converts the rotational motion of the rotating sleeve 1 into the linear motion of the atomizing device 200; when the atomizing device 200 needs to be used, control the rotating sleeve 1 to rotate relative to the base 3, and the arc-shaped groove 5 cooperates with the adjusting member 7 to make the adjusting member 7 move along the first direction X in the linear groove 6 of the base 3, thereby driving the atomizing device 200 to move along the first direction X; control the top cover 2 to open the avoidance port 103, and the atomizing device 200 passes through the avoidance port 103 and protrudes outside the rotating sleeve 1 to meet the user's suction use of the atomizing device 200; when the rotating sleeve 1 rotates in the reverse direction, the atomizing device 200 can be reset and moved to shrink inside the rotating sleeve 1 again, and control the top cover 2 to close the avoidance port 103 to isolate the nozzle part 2001 from the external air and form an effective protection for the atomizing device 200.

[0061] In addition, according to the specification size of the atomizing device 200, an outer cover assembly 100 adapted thereto can be set. After the rotating sleeve 1 is sleeved outside the atomizing device 200, the adjusting member 7 can be connected to the outer wall surface of the atomizing device 200 through the arc-shaped groove 5. Then, the assembly between the outer cover assembly 100 and the atomizing device 200 is convenient and fast, and the adaptability of the outer cover assembly 100 is wide.

[0062] Reference Figure 3 、 Figure 6 、 Figure 7 In some embodiments, the outer cover assembly 100 further includes a rotation limiting structure 8. The rotation limiting structure 8 includes a limiting ring groove 801 provided on one of the base 3 and the rotating sleeve 1, and a limiting block 802 provided on the other of the base 3 and the rotating sleeve 1; the limiting block 802 can move along the limiting ring groove 801 in the first plane, and the first plane is perpendicular to the first direction X; the movement stroke of the limiting block 802 in the limiting ring groove 801 is the rotation stroke between the rotating sleeve 1 and the base 3.

[0063] It can be understood that the rotation between the rotating sleeve 1 and the base 3 is limited by the limiting block 802 and the limiting ring groove 801; when the limiting block 802 moves to both ends of the limiting ring groove 801, the inner wall of the limiting ring groove 801 will abut against the limiting block 802 to limit the movement of the limiting block 802, thereby restricting the rotation of the rotating sleeve 1. The rotating sleeve 1 can only rotate within a certain angle, restricting the excessive rotation of the rotating sleeve 1 and improving the rotation stability. The limiting block 802 can move along the limiting ring groove 801 in the first plane. Then, during the rotation of the rotating sleeve 1 relative to the base 3, there is no relative displacement between the rotating sleeve 1 and the base 3 in the first direction X.

[0064] It can be understood that the limiting block 802 being embedded in the limiting ring groove 801 can also limit the rotating sleeve 1 from detaching from the base 3 in the first direction X, playing a role in structural limitation.

[0065] refer to Figure 6 , Figure 7 In some embodiments, the base 3 is a sleeve structure, a limit block 802 protruding outward is provided on the outer wall of the rotating sleeve 1, and a limit ring groove 801 is provided on the inner wall of the base 3; the base 3 is sleeved outside the rotating sleeve 1 so that the limit block 802 is embedded in the limit ring groove 801.

[0066] In some other embodiments, the base 3 is a sleeve structure, a limiting ring groove 801 is provided on the outer wall of the rotating sleeve 1 , and a protruding limiting block 802 is provided on the inner wall of the base 3 .

[0067] In some embodiments, at least two pairs of matching limiting blocks 802 and limiting ring grooves 801 are provided between the rotating sleeve 1 and the base 3 , so that the limiting structure is stable and the rotating sleeve 1 can rotate stably and smoothly relative to the base 3 .

[0068] refer to Figure 1 , Figure 3 , Figure 6 In some embodiments, the rotating sleeve 1 includes a first sleeve body 11 and a second sleeve body 12 connected along a first direction X; the outer diameter of the first sleeve body 11 is greater than the outer diameter of the second sleeve body 12; the base 3 is sleeved on the outside of the second sleeve body 12 and abuts against the first sleeve body 11 in the first direction X; an arc groove 5 is provided on the second sleeve body 12.

[0069] It can be understood that the outer diameter of the first sleeve 11 is larger than the outer diameter of the second sleeve 12, and then a step is formed at the connection between the first sleeve 11 and the second sleeve 12; the base 3 is sleeved outside the second sleeve 12, and the end of the base 3 close to the first sleeve 11 abuts on the step; the rotating sleeve 1 can be controlled to rotate relative to the base 3 by acting on the first sleeve 11, and the handheld operation is convenient; and there is good structural support between the base 3 and the rotating sleeve 1, and the rotating sleeve 1 can rotate stably relative to the base 3.

[0070] refer to Figure 7 In some embodiments, the base 3 includes a bottom plate 301 and a bottom sleeve 302 disposed on the bottom plate 301, and the bottom sleeve 302 is formed with a linear groove 6; the bottom sleeve 302 is sleeved outside the second sleeve 12; and the outer diameter of the bottom sleeve 302 is equal to the outer diameter of the first sleeve 11.

[0071] It can be understood that the outer diameter of the bottom sleeve 302 is equal to the outer diameter of the first sleeve 11. After the bottom sleeve 302 is sleeved on the outside of the second sleeve 12 and connected to the first sleeve 11, the connection between the bottom sleeve 302 and the first sleeve 11 is smooth, which can improve the structural integrity of the outer cover assembly 100; it is convenient for users to grasp the bottom sleeve 302 and the first sleeve 11, and improves the feel of use.

[0072] It is understandable that the bottom of the atomizing device 200 is usually provided with a charging interface, seeFigure 7 An opening 3011 is correspondingly provided on the bottom plate 301 , which does not affect the charging of the atomizing device 200 .

[0073] refer to Figure 7 In some embodiments, the base 3 further includes at least two spaced-apart convex strips 10 disposed on the inner wall surface of the bottom sleeve 302, and the convex strips 10 extend along the first direction X; two adjacent convex strips 10 and the inner wall surface of the bottom sleeve 302 enclose a linear groove.

[0074] It can be understood that by providing a convex strip 10 on the inner wall surface of the bottom sleeve 302 to enclose a linear groove 6, the adjustment member 7 can be effectively restricted within the linear groove 6; and no groove structure will be formed on the outer wall surface of the bottom sleeve 302, so that the outer wall of the outer cover assembly 100 is flat.

[0075] refer to Figure 4 , Figure 5 In some embodiments, the arc groove 5 includes a proximal end 501 and a distal end 502 that are opposite to each other, and the proximal end 501 is closer to the first end 101 in the first direction X relative to the distal end 502; when the adjustment member 7 moves from the distal end 502 to the proximal end 501, the suction nozzle portion 2001 extends from the rotating sleeve 1 to the outside of the rotating sleeve 1.

[0076] It can be understood that there is a height difference between the proximal end 501 and the distal end 502 of the arc-shaped groove 5 in the first direction X. During the rotation of the rotating sleeve 1 relative to the base 3, the adjusting member 7 moves between the proximal end 501 and the distal end 502 of the arc-shaped groove 5 to move in the first direction X, so that the atomizing device 200 telescopically moves relative to the rotating sleeve 1 along the first direction X; during the movement of the adjusting member 7 from the distal end 502 to the proximal end 501, the atomizing device 200 extends from the inside to the outside relative to the rotating sleeve 1; during the movement of the adjusting member 7 from the proximal end 501 to the distal end 502, the atomizing device 200 contracts from the outside to the inside relative to the rotating sleeve 1. Therefore, the movement stroke of the adjusting member 7 in the arc-shaped groove 5 is the telescopic stroke of the atomizing device 200 relative to the rotating sleeve 1.

[0077] refer to Figure 3 , Figure 6 , Figure 7 In some embodiments, the outer cover assembly 100 includes at least two groups of rotating telescopic structures 4 arranged circumferentially around the first direction X; each group of rotating telescopic structures 4 includes a matching adjustment member 7, an arc groove 5 and a straight groove 6; and each arc groove 5 is distributed in a circumferential array on the rotating sleeve 1.
