Description

Technical Field

[0001] The present invention belongs to the technical field of atomization, and particularly relates to an atomization device and an aerosol generating device. Background Art

[0002] Existing aerosol generating devices include an oil storage cavity and an atomization core. The atomization core has an atomization channel which is respectively communicated with a mouthpiece and an air inlet. The atomization core heats and atomizes the oil injected from the oil storage cavity to generate aerosol in the atomization channel. Users suck through the mouthpiece to cause a negative pressure change, thereby sucking the generated aerosol into the mouth. However, the mouthpiece and the air inlet of existing aerosol generating devices or atomization devices are in an open state. After being placed for a long time, the oil at the atomization core is likely to absorb water, resulting in a change in the taste of the aerosol or an oil explosion phenomenon during heating. Moreover, after the conventional atomization core is filled with oil, it is very easy to leak oil due to air pressure changes and temperature changes. When the aerosol generating device is put into a bag or pocket after use, there is often more or less condensate and oil seeping out, resulting in contamination of the bag and clothes. Especially when taking a plane, the oil leakage is very serious. In addition, when there is oil stain on the surface of the aerosol generating device or the atomization device, the whole machine cannot be cleaned, and directly scrapping the atomization core may occur during cleaning.

[0028] An embodiment of the present invention provides an aerosol generating device. The aerosol generating device includes an atomizing device 100 as shown in Figure 1 and a battery rod (not shown) detachably assembled with the atomizing device 100. The battery rod supplies power to the atomizing core inside the atomizing device 100, so that the atomizing core heats and atomizes the atomizing liquid in the atomizing device 100 when in the working state, and the generated aerosol can be output through the mouthpiece on the atomizing device 100 for the user to inhale.

[0029] Please refer to Figure 2 and Figure 3 As shown, the atomizing device 100 of the embodiment of the present invention includes a housing 10, an atomizing core 20, a mouthpiece 30, and a closing member 40. The housing 10 has an oil storage chamber 14, an air outlet passage 15, and an air inlet passage 16. The atomizing core 20 is disposed in the oil storage chamber 14. The atomizing core 20 has an atomizing passage 21, and the atomizing passage 21 communicates with the air outlet passage 15 and the air inlet passage 16 respectively. The mouthpiece 30 is installed on the housing 10 and communicates with the air outlet passage 15. The closing member 40 is slidably connected to the housing 10 and can move between a first position and a second position to open or close the air outlet passage 15 and the air inlet passage 16.

[0030] In this embodiment, when the atomizing device 100 needs to be used, the closing member 40 is moved to the first position, so that the air outlet passage 15 and the air inlet passage 16 are in an open state, that is, the air inlet passage 16, the atomizing passage 21, the air outlet passage 15, and the mouthpiece 30 are sequentially connected. The aerosol generated when the atomizing core 20 works can be inhaled by the user through a sucking action, realizing the normal use function; when the atomizing device 100 does not need to be used, the closing member 40 is moved to the second position, so that the air outlet passage 15 and the air inlet passage 16 are in a closed state, that is, the atomizing passage 21 of the atomizing core 20 is in a completely closed state, thereby realizing the fully sealed waterproof function of the atomizing core 20, avoiding the phenomenon of water ingress or oil leakage of the atomizing core 20, ensuring the inhalation taste of the aerosol, and the whole machine can be cleaned, which is convenient to use.

[0031] Specifically, an air inlet cavity 17 and a communication cavity 18 are further formed in the housing 10. The air inlet cavity 17 and the communication cavity 18 are respectively located on the upper and lower sides of the oil storage cavity 14. The air outlet passage 15 is formed in the air inlet cavity 17. One end of the atomizing passage 21 is communicated with the air inlet passage 16, and the other end is communicated with the communication cavity 18. The air inlet passage 16 penetrates through the oil storage cavity 14 up and down and is respectively communicated with the air inlet cavity 17 and the communication cavity 18. The closing member 40 is slidably arranged in the air inlet cavity 17.

[0032] That is to say, the lower end of the atomizing passage 21 and the lower end of the air inlet passage 16 are communicated through the communication cavity 18. The upper end of the atomizing passage 21 is communicated with the mouthpiece 30 through the air outlet passage 15 passing through the air inlet cavity 17. When the closing member 40 is moved to the second position, the communication between the air inlet cavity 17 and the air inlet passage 16, and the communication between the atomizing passage 21 and the air outlet passage 15 are cut off, so that the atomizing passage 21 of the atomizing core 20 is in a closed state.

[0033] In one embodiment, the housing 10 includes a main body 11, an upper cover 12, and a lower cover 13. The main body 11 includes a bottom wall 111, a side wall 112 bent and extended along the bottom wall 111, and a partition 113 opposite to the bottom wall 111 and hermetically connected to the side wall 112. The bottom wall 111, the side wall 112, and the partition 113 jointly enclose the oil storage cavity 14. The bottom wall 111 protrudes and extends towards the partition 113 to form a communication pipe 114. The communication pipe 114 penetrates through the bottom wall 111. The partition 113 is provided with a first air inlet hole 1131 corresponding to the position of the communication pipe 114.

[0034] The upper cover 12 is hermetically covered on the upper end of the main body 11 and jointly encloses the air inlet cavity 17 with the side wall 112 and the partition 113; the closing member 40 can move horizontally between the side wall 112 and the partition 113 to open or close the air outlet passage 15 and the air inlet passage 16.

[0035] The lower cover 13 is hermetically covered on the lower end of the main body 11, and together with the side wall 112 and the bottom wall 111, it encloses a communication cavity 18; wherein, the bottom wall 111 is recessed away from the lower cover 13 to form a groove, and when the lower cover 13 is covered on the lower end of the main body 11, the groove is closed to form the communication cavity 18.

[0036] It should be noted that a step is formed at a position near the upper end on the inner side of the side wall 112, and the partition plate 113 is arranged on this step surface. When the upper cover 12 is covered on the upper end of the main body 11, the partition plate 113 is firmly pressed on this step surface, so as to form a sealed oil storage cavity 14 inside the main body 11.

[0037] In addition, the bottom wall 111 is also provided with an oil injection hole penetrating through the lower cover 13. Through this oil injection hole, oil can be added to the oil storage cavity 14, and it is blocked by a sealing plug 19. When the atomizing device 100 is assembled with the battery rod, the sealing plug 19 is located between the atomizing device 100 and the battery rod, ensuring the sealing performance of the oil injection hole.

[0038] Furthermore, as shown in Figure 4 the partition plate 113 protrudes and extends towards the upper cover 12 to form an annular protrusion 1132 abutting against the upper cover 12, and the partition plate 113 is provided with a through air outlet hole 1133 inside the annular protrusion 1132. The annular protrusion 1132 defines an air outlet channel 15; that is, the air outlet hole 1133 is respectively communicated with the air outlet channel 15 and the atomizing channel 21.

[0039] A through hole is opened on the upper cover 12 at a position corresponding to the air outlet channel 15, and a nozzle seat 122 is formed by protruding around the periphery of this through hole. The nozzle 30 is fixedly installed on the nozzle seat 122, so as to be communicated with the air outlet channel 15.

[0040] Preferably, a second air inlet hole 123 is penetrated through the upper cover 12 at a position near the nozzle 30. A protective sleeve 31 is also sleeved outside the nozzle 30. The protective sleeve 31 covers the second air inlet hole 123 and is provided with a third air inlet hole 32 communicated with the second air inlet hole 123.

[0041] It should be understood that an annular cavity 33 is formed jointly by the inner side surface of the protective sleeve 31, the outer side surface of the nozzle 30 and the outer side surface of the upper cover 12. The third air inlet hole 32 on the protective sleeve 31 is communicated with the second air inlet hole 123 on the upper cover 12 through this annular cavity 33. When the closing member 40 is in the first position and the user sucks, the air outside the atomizing device 100 sequentially passes through the third air inlet hole 32, the annular cavity 33, the second air inlet hole 123, the air inlet cavity 17, the first air inlet hole 1131, the air inlet channel 16 and the communication cavity 18, and then enters the atomizing channel 21 to be mixed with the aerosol and is output from the nozzle 30 through the air outlet channel 15 for the user to inhale.

[0042] In one embodiment, a guiding hole 121 is formed in the upper cover 12. The closing member 40 includes a sliding plate 41 that slides between the upper cover 12 and the partition plate 113, and a dial block 42 connected to the sliding plate 41, and the dial block 42 extends out of the guiding hole 121. By moving the dial block 42 in the guiding hole 121, the closing member 40 is moved between a first position and a second position to open or close the air outlet channel 15 and the air inlet channel 16.

[0043] Specifically, the sliding plate 41 includes a first closing portion 411 and a second closing portion 412. The first closing portion 411 is a strip-shaped structure, and its width is smaller than the width of the second closing portion 412. One end of the first closing portion 411 away from the second closing portion 412 penetrates into the annular protrusion 1132, and the other end is connected to the second closing portion 412. The dial block 42 is arranged on the second closing portion 412. The number of the first air inlet holes 1131 is two, and they are respectively located on both sides of the width direction of the first closing portion 411. Correspondingly, two communication pipes 114 are also formed in the main body 11, and the two communication pipes 114 are respectively and hermetically communicated with the two first air inlet holes 1131. In this embodiment, the width of the second closing portion 412 is adapted to the width of the air inlet cavity 17, which improves the stability of the sliding of the closing member 40.

[0044] When the closing member 40 moves from the first position to the second position, the end of the first closing portion 411 extends into the annular protrusion 1132 to cover the air outlet hole 1133, so as to cut off the air outlet channel 15 and the atomization channel 21. At the same time, the second closing portion 412 covers the two first air inlet holes 1131 to cut off the connection between the air inlet cavity 17 and the two air inlet channels 16.

[0045] In one embodiment, the atomization core 20 is fixedly arranged through the lower cover 13 and the bottom wall 111, the upper end is hermetically communicated with the air outlet hole 1133, the lower end is exposed outside the lower cover 13, and the part of the atomization core 20 located in the communication cavity 18 is provided with fourth air inlet holes 22 respectively, so that the communication cavity 18 is communicated with the atomization channel 21 through the fourth air inlet holes 22. Thus, when the external space enters the communication cavity 18 through the air inlet channel 16, it enters the atomization channel 21 through the fourth air inlet holes 22, and then is mixed with the aerosol generated by the atomization core 20 and output through the air outlet channel 15 and the mouthpiece 30.

[0046] It should be noted that the part of the atomization core 20 leaking out of the lower cover 13 includes a conductive contact 23 electrically connected to its heating element. When the atomization device 100 is assembled with the electronic rod to form an aerosol generating device, the conductive contact 23 is electrically connected to the battery rod, so as to realize the electrical connection between the atomization core 20 and the battery rod.

[0047] Further, in order to avoid oil leakage at the connection between the atomizing core 20 and the housing 10 and ensure the sealing performance of the oil storage cavity 14, a sleeve pipe is formed by the partition plate 113 protruding and extending towards the bottom wall 111 along the periphery of the air outlet hole 1133. The upper end of the atomizing core 20 is hermetically sleeved in the sleeve pipe through a first sealing plug. A second sealing ring is provided between the atomizing core 20 and the bottom wall 111, and a third sealing ring is provided between the atomizing core 20 and the lower cover 13.

[0048] In the above embodiments, the descriptions of the respective embodiments have their own focuses. For the parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0049] The above is the description of the technical solution provided by the present invention. For those skilled in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
