Abstract
Description
Technical Field
[0001] This application relates to the technical field of electronic atomization, and particularly relates to an atomizer and an electronic atomization device. Background Art
[0002] As a substitute for traditional cigarettes, an electronic atomization device generally includes a power supply device and an atomizer, and the power supply device is used to supply power to the atomizer. Among them, the atomizer generally includes a hollow shell and an atomization core disposed inside the shell. An atomization channel and a liquid storage cavity for supplying atomization liquid to the atomization core are also provided inside the shell. The atomization core is used to heat and atomize the atomization liquid supplied by the liquid storage cavity to form an inhalable aerosol leading to the atomization channel. The upper part of the shell has a suction port communicating with the atomization channel, and the suction port is used for the user to inhale the formed aerosol.
[0003] In related technologies, the atomization core includes an oil guiding body and a heating element disposed on the oil guiding body. A lower oil hole communicating with the bottom of the liquid storage cavity is provided on the inner side wall of the atomization channel. The oil guiding body is disposed in the atomization channel and at the position of the lower oil hole. The lower oil hole is used to guide the atomization liquid in the liquid storage cavity to the oil guiding body, the oil guiding body is used to guide the atomization liquid to the heating element, and the heating element is used to heat and atomize the atomization liquid. However, the posture of the electronic atomization device during use depends on the user, that is, the posture of the atomizer during use is random. When the atomization liquid in the liquid storage cavity is consumed and no longer fills the entire liquid storage cavity, the atomization liquid in the liquid storage cavity is likely to fail to flow to the position of the lower oil hole due to the poor posture of the atomizer during use, so that the atomization liquid in the liquid storage cavity cannot flow to the oil guiding body through the lower oil hole, and further causes the heating element to dry burn due to insufficient liquid supply during user suction. This will not only produce a burnt smell and affect the user experience, but also affect the service life of the atomizer. Summary of the Utility Model

[0032] Referring to Figures 1 to 5 , the atomizer according to the embodiment of the present application includes a housing 100, an atomization core, and an oil guiding structure.
[0033] Specifically, the housing 100 has a hollow internal structure. An atomization channel 200 and a liquid storage cavity 300 for storing atomization liquid are provided inside the housing 100. A lower oil hole 400 communicating with the bottom of the liquid storage cavity 300 is provided on the inner side wall of the atomization channel 200. The atomization core includes an oil guiding body 510 and a heating body 520 disposed on the oil guiding body 510. The oil guiding body 510 is disposed in the atomization channel 200 and at the position of the lower oil hole 400. The lower oil hole 400 is used to guide the atomization liquid in the liquid storage cavity 300 to the oil guiding body 510. The oil guiding body 510 is used to guide the atomization liquid to the heating body 520. The heating body 520 is used to heat and atomize the atomization liquid to form an inhalable aerosol leading to the atomization channel 200. The oil guiding structure is a porous medium. The oil guiding structure includes an annular portion 610 and a convex portion 620. Both the annular portion 610 and the convex portion 620 are disposed in the liquid storage cavity 300. The shape of the cross-section of the annular portion 610 is adapted to the shape of the cross-section of the liquid storage cavity 300, so that the outer peripheral side wall of the annular portion 610 fits against the inner peripheral side wall of the liquid storage cavity 300. One end of the convex portion 620 is connected to the annular portion 610, and the other end of the convex portion 620 extends to the position of the lower oil hole 400. In addition, an inhalation port 110 communicating with the atomization channel 200 is provided at the upper part of the housing 100. The inhalation port 110 is used for the user to inhale the generated aerosol.
[0034] An oil guiding structure is provided in the liquid storage cavity 300. When the posture of the atomizer during use is not good, the oil guiding structure can assist in guiding the atomization liquid. Specifically, since the shape of the cross-section of the annular portion 610 is adapted to the shape of the cross-section of the liquid storage cavity 300, so that the outer peripheral side wall of the annular portion 610 fits against the inner peripheral side wall of the liquid storage cavity 300. When the use posture of the atomizer is in a horizontal state or in an inclined state with the inhalation port 110 facing upward, the annular portion 610 can contact the atomization liquid in the liquid storage cavity 300 and guide the contacted atomization liquid to the lower oil hole 400 through the convex portion 620 extending to the position of the lower oil hole 400, thereby helping to prevent the heating body 520 from dry burning due to insufficient liquid supply.
[0035] Refer to Figures 1 to 3 , in some of the embodiments, an airway member 700 and an atomization bracket 800 are provided inside the housing 100. The airway member 700 and the atomization bracket 800 enclose to form the atomization channel 200. The lower oil hole 400 is formed on the atomization bracket 800. Of course, the atomization channel 200 can also be independently formed inside the housing 100, that is, the formation of the atomization channel 200 does not depend on components outside the housing 100, and this is not limited herein.
[0036] It should be noted that, in some of the embodiments, the number of the lower oil holes 400 is multiple, which is beneficial to improving the guiding effect.
[0037] It should be noted that in some of the embodiments, the oil guiding body 510 is a rigid porous medium, such as porous ceramic or porous glass.
[0038] It should be noted that in some other embodiments, the oil guiding body 510 can also be a soft porous medium, such as oil guiding cotton, which is not limited herein.
[0039] It should be noted that in some of the embodiments, the annular part 610 and the convex part 620 are rigid porous medium, such as porous ceramic or porous glass.
[0040] It should be noted that in some other embodiments, the annular part 610 and the convex part 620 can also be soft porous medium, such as oil guiding cotton, which is not limited herein.
[0041] It should be noted that in some of the embodiments, the heating element 520 is a heating wire or a heating film attached to the oil guiding body 510, which is not limited herein.
[0042] Refer to Figure 1 and Figure 5 , in some of the embodiments, the annular part 610 is arranged at the lower part of the liquid storage cavity 300, and the oil guiding structure further includes an extension part 630. One end of the extension part 630 is connected to the annular part 610, and the other end of the extension part 630 extends towards the top of the liquid storage cavity 300. By providing the extension part 630 extending towards the top of the liquid storage cavity 300, the acting range of the oil guiding structure can be increased. When the posture of the atomizer during use is not good, the oil guiding structure can better assist in guiding the atomized liquid, which is beneficial to further prevent the heating element 520 from dry burning due to insufficient liquid supply.
[0043] It should be noted that in some of the embodiments, the extension part 630 is a rigid porous medium, such as porous ceramic or porous glass.
[0044] It should be noted that in some other embodiments, the extension part 630 can also be a soft porous medium, such as oil guiding cotton, which is not limited herein.
[0045] It should be noted that in some of the embodiments, the extension part 630 extends to the top of the liquid storage cavity 300, which can further increase the acting range of the oil guiding structure.
[0046] Refer to Figure 5, in some of these embodiments, the cross-section of the extension portion 630 is annular, and the shape of the cross-section of the extension portion 630 is adapted to the shape of the cross-section of the liquid storage cavity 300, so that the outer peripheral side wall of the extension portion 630 fits against the inner peripheral side wall of the liquid storage cavity 300. Since the extension portion 630 extends to the top of the liquid storage cavity 300, and the shape of the cross-section of the extension portion 630 is adapted to the shape of the cross-section of the liquid storage cavity 300, so that the outer peripheral side wall of the extension portion 630 fits against the inner peripheral side wall of the liquid storage cavity 300, when the use posture of the atomizer is in an inverted state or an inclined state with the suction port 110 facing downwards, the extension portion 630 can contact the atomizing liquid in the liquid storage cavity 300, and guide the contacted atomizing liquid to the lower oil hole 400 through the annular portion 610 and the convex portion 620 extending to the lower oil hole 400, thereby facilitating preventing the heating element 520 from dry burning due to insufficient liquid supply. That is to say, at this time, regardless of the use posture of the atomizer, the oil guiding structure can contact the atomizing liquid in the liquid storage cavity 300 and guide the contacted atomizing liquid to the lower oil hole 400. It should be noted that there are a total of five cases for the use posture of the atomizer. The first case is that the use posture of the atomizer is in a horizontal state, the second case is that the use posture of the atomizer is in an inclined state with the suction port 110 facing upwards, the third case is that the use posture of the atomizer is in an inclined state with the suction port 110 facing downwards, the fourth case is that the use posture of the atomizer is in an inverted state with the suction port 110 facing downwards, and the fifth case is that the use posture of the atomizer is in a vertical state with the suction port 110 facing upwards.
[0047] Referring to Figure 4 and Figure 5 , in some of these embodiments, a plurality of raised ribs 120 are spaced apart on the inner peripheral side wall of the liquid storage cavity 300, the ribs 120 extend towards the top of the liquid storage cavity 300, and a plurality of avoidance notches 631 corresponding to the plurality of ribs 120 are provided on the extension portion 630. When assembling the oil guiding structure, through the cooperation and positioning of the ribs 120 on the inner peripheral side wall of the liquid storage cavity 300 and the avoidance notches 631 on the extension portion 630, the position of the oil guiding structure can be prevented from shifting during the working process, which is beneficial to improving the stability and reliability of the oil guiding structure.
[0048] It should be noted that in some other embodiments, at least two spaced-apart extension portions 630 are connected to the annular portion 610. A filling portion (not shown in the figure) is provided at one end of the extension portion 630 away from the annular portion 610. All the filling portions completely fill the top region of the liquid storage cavity 300. Since all the filling portions completely fill the top region of the liquid storage cavity 300, when the use posture of the atomizer is in an inverted state or an inclined state with the suction port 110 facing downwards, the filling portions can all contact the atomizing liquid in the liquid storage cavity 300, and guide the contacted atomizing liquid to the lower oil hole 400 through the extension portion 630, the annular portion 610, and the protrusion portion 620 extending to the lower oil hole 400, thereby facilitating preventing the heating element 520 from dry burning due to insufficient liquid supply. Similarly, at this time, regardless of the use posture of the atomizer, the oil guiding structure can contact the atomizing liquid in the liquid storage cavity 300 and guide the contacted atomizing liquid to the lower oil hole 400.
[0049] It should be noted that in some of these embodiments, at least one of the extension portion 630 and the protrusion portion 620 is integrally formed on the annular portion 610. Specifically, it can be that both the extension portion 630 and the protrusion portion 620 are integrally formed on the annular portion 610, or only the extension portion 630 is integrally formed on the annular portion 610, or only the protrusion portion 620 is integrally formed on the annular portion 610, which is not limited herein.
[0050] It should be noted that in some of these embodiments, at least one of the extension portion 630 and the protrusion portion 620 is detachably connected to the annular portion 610. Specifically, it can be that both the extension portion 630 and the protrusion portion 620 are detachably connected to the annular portion 610, or only the extension portion 630 is detachably connected to the annular portion 610, or only the protrusion portion 620 is detachably connected to the annular portion 610, which is not limited herein.
[0051] In the above structure, the detachable connection can be achieved through a snap structure, or through screws or other structures, which is not limited herein.
[0052] It should be noted that in some of these embodiments, the volume of the oil guiding structure is smaller than the volume of the liquid storage cavity 300. Compared with the integrated oil storage cotton in the related art, less material is used, which is beneficial to reducing costs.
[0053] It should be noted that in some of these embodiments, the protrusion portion 620 is made of oil guiding cotton. There is a gap for accommodating the protrusion portion 620 between the inner side wall of the liquid storage cavity 300 and the outer side wall of the atomization channel 200. The protrusion portion 620 is in interference fit with this gap, so that the protrusion portion 620 is squeezed and contacts the oil guiding body 510 through the lower oil hole 400, which is beneficial to improving the effect of the oil guiding structure assisting in guiding the flow.
