Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generation, in particular, to an electronic atomization device. BACKGROUND

[0002] The electronic atomization device is an apparatus that can heat a liquid aerosol generating substrate to generate an aerosol. The electronic atomization device has an air flow sensor for sensing a puffing state. When the air flow sensor senses air flow movement, the air flow sensor generates a feedback signal to a control module. The control module controls the atomization module to heat the aerosol generating substrate based on the received feedback signal, so that the heated aerosol generating substrate is atomized to form an aerosol.

[0003] Since the atomized aerosol remains in the electronic atomization device and forms condensate after cooling down, the condensate aggregation may affect the service life of the air flow sensor. In the prior art, the detection air channel is usually designed as a winding extension structure to increase the difficulty of movement of the remaining aerosol to the air flow sensor and the difficulty of movement of the condensate to the air flow sensor. However, such an extension structure may increase the risk of condensate accumulation and block the detection air channel or condensate intrusion and damage the air flow sensor due to the increased amount of aerosol remaining in the air channel. In addition, the extended air channel may affect the response speed of the air flow sensor. Therefore, the existing detection air channel needs to be improved. CONTENT OF THE UTILITY MODEL

[0048] Referring to Figure 1 As shown in the drawings, the present application provides an electronic atomization device 100, which comprises a housing 1 and a mouthpiece 2 embedded on the housing 1 and at least partially protruding out of the housing 1.

[0049] Referring to Figures 2-4 As shown in the drawings, the electronic atomization device 100 further comprises a receiving member 3, a sealing member 4, an airflow sensor 5, an atomization member 6, a sealing seat 7, a liquid suction member 8, a sealing sleeve 9, a sealing rubber sleeve 10 and a control circuit board 11 respectively arranged in the housing 1.

[0050] The sealing member 4 is sealingly connected between the mouthpiece 2 and the receiving member 3, and cooperates with the mouthpiece 2 and the receiving member 3 to form a detection air channel, and the airflow sensor 5 is sealingly arranged on the receiving member 3 through the sealing sleeve 9 and located in the detection air channel.

[0051] The sealing seat 7 is sealingly arranged at an end of the receiving member 3 away from the sealing member 4, and cooperates with the receiving member 3, the sealing member 4 and the mouthpiece 2 to form an atomization air channel, and cooperates with the receiving member 3 and the sealing member 4 to form a liquid storage bin 12 for receiving liquid aerosol substrate.

[0052] The atomization member 6 is sealingly arranged on the receiving member 3 through the sealing rubber sleeve 10, and is used to heat the aerosol substrate under the condition of being powered on, so that the heated aerosol is atomized to form aerosol released to the atomization channel.

[0053] The liquid suction member 8 is arranged between the mouthpiece 2 and the sealing member 4, and is used to suck and lock the condensed liquid in the mouthpiece 2, which is formed after the aerosol remaining in the electronic atomization device 100 is cooled.

[0054] The control circuit board 11 is arranged in a mounting space 13 enclosed by the sealing seat 7 and the shell 1, and the control circuit board 11 is electrically connected with the atomizing element 6 and the airflow sensor 5 respectively, and receives the feedback signal of the airflow sensor 5 in the state of being powered on to control the atomizing element 6 to heat.

[0055] Further, the suction nozzle 2 is configured to form a first sub-detection air channel 21; the accommodation element 3 is configured to form a second sub-detection air channel 31 and a mounting cavity 32 which are in communication with each other. The accommodation element 3 and the suction nozzle 2 are sealingly connected to form the detection air channel, and the detection air channel includes the first sub-detection air channel 21, the second sub-detection air channel 31 and the mounting cavity 32 which are in communication in sequence.

[0056] Further, referring to Figure 4 As shown in the figure, the mounting cavity 32 includes a first cavity 321 and a second cavity 322. The first cavity 321 is in communication between the second sub-detection air channel 31 and the second cavity 322, and the airflow sensor 5 is sealingly arranged in the second cavity 322, and the detection surface 51 of the airflow sensor 5 faces the first cavity 321.

[0057] Referring to Figure 5 As shown in the figure, the accommodation element 3 includes a first enclosing part 33 and a second enclosing part 34. The first enclosing part 33 and the second enclosing part 34 are arranged in the first cavity 321 respectively and extend towards the second cavity 322 respectively. Among them, the first enclosing part 33 has a first opening, and the first opening faces away from the second sub-detection air channel 31; the second enclosing part 34 has a second opening 341, and the second opening 341 faces the second sub-detection air channel 31, and the part of the second enclosing part 34 close to the second opening 341 is located in the first opening, and the second enclosing part 34 is configured to form an enclosing space 326, and the detection surface 51 faces the enclosing space 326 of the second enclosing part 34, so that the airflow sensor 5 can only generate the feedback signal in the state that the airflow in the enclosing space 326 flows.

[0058] Further, since the first opening and the second opening 341 are opposite to each other, and the second opening 341 is located in the first opening, when the user inhales, the airflow that triggers the airflow sensor 5 to generate a feedback detection signal will change direction from the surrounding space 326, pass through the second opening 341, pass through the space between the first surrounding part 33 and the second surrounding part 34, then change direction again to pass through the space between the first surrounding part 33 and the inner wall of the first cavity 321, enter the second sub-detection air passage 31, and finally flow out through the first sub-detection air passage 21 and diffuse to the first sub-detection air passage 21 and the second sub-detection air passage 31. The condensed liquid formed after the aerosol is condensed will gather in the space between the second surrounding part 34 and the first cavity 321 under the blocking and guiding of the first sub-surrounding part, thereby avoiding the condensed liquid from entering the surrounding space 326 to affect the normal use of the airflow sensor 5, and avoiding the condensed liquid from blocking the detection air passage.

[0059] Further, please continue to refer to Figure 5 As shown, the first outer side wall 332 of the first surrounding part 33 and the inner wall of the first cavity 321 are spaced apart to form a first space 323. The first inner side wall 333 of the first surrounding part 33 and the corresponding second outer side wall 342 of the second surrounding part 34 are spaced apart to form a second space 324. The second inner side wall 343 of the second surrounding part 34 forms the surrounding space 326. The second outer side wall 342 of the second surrounding part 34 and the corresponding inner wall of the first cavity 321 are spaced apart to form a liquid collecting space 325. The liquid collecting space 325, the second space 324 and the first space 323 are in communication.

[0060] When the user inhales, the detection airflow sensed by the detection surface 51 flows out in sequence through the surrounding space 326, the second space 324, the first space 323, the second sub-detection air passage 31 and the first sub-detection air passage 21.

[0061] When the condensed liquid is collected, it flows in sequence through the first sub-detection air passage 21, the second sub-detection air passage 31 and the first space 323 to the liquid collecting space 325.

[0062] Preferably, a liquid storage member can be further arranged in the liquid collecting space 325, and the liquid storage member is used to absorb and lock the condensed liquid. The liquid storage member can be sponge, cotton or other materials that can absorb condensed liquid.

[0063] Further, please refer to Figures 6-9As shown, the first enclosing part 33 is one of a semicircular structure, a V-shaped structure, a C-shaped structure, and a door-shaped structure, wherein the first opening is away from the second sub-detection air channel 31; the second enclosing part 34 is one of a semicircular structure, a V-shaped structure, a C-shaped structure, and a door-shaped structure, wherein the second opening 341 is towards the second sub-detection air channel 31.

[0064] Further, referring to Figures 10-11 As shown, the first enclosing part 33 can also be a structure in which the opening end is relatively close on the basis of the above-mentioned semicircular structure, V-shaped structure, C-shaped structure, and door-shaped structure; the second enclosing part 34 can also be a structure in which the opening end is relatively far away on the basis of the above-mentioned semicircular structure, V-shaped structure, C-shaped structure, and door-shaped structure.

[0065] Further, referring to Figures 2-4 As shown, the airflow sensor 5 is sealed in the second cavity 322 by the sealing sleeve 9. The sealing sleeve 9 includes an end part 91 and a ring part 92 which are integrally formed. The end part 91 and the ring part 92 are sealingly connected in a structure formed with a sealing groove 93. The ring part 92 is sealingly connected between the circumferential side of the airflow sensor 5 and the inner wall of the second cavity 322; the end part 91 is abutted between the detection face 51 and at least the second end face 344 of the second enclosing part 34 towards the second cavity 322, so that the detection face 51 is directly communicated with only the enclosing space 326, and is not directly communicated with the second space 324 and the liquid collecting space 325.

[0066] Preferably, the end part 91 is simultaneously abutted between the detection face 51 and the first end face 334 of the first enclosing part 33 towards the second cavity 322, and between the detection face 51 and the second end face 344.

[0067] Further, referring to Figure 2 As shown, the end part 91 is provided with at least one through hole 94, which is communicated between the enclosing space 326 and the detection face 51, and is used for communicating the detection face 51 with the enclosing space 326.

[0068] Further, referring to Figures 2-4 and Figure 12 As shown, the sealing member 4 is configured to form a third sub-detection air channel 41 which is communicated between the first sub-detection air channel 21 and the second sub-detection air channel 31. The detection air channel includes the first sub-detection air channel 21, the third sub-detection air channel 41, the second sub-detection air channel 31, and the mounting cavity 32 which are sequentially communicated.

[0069] Further, the sealing member 4 comprises a sealing body 42 and a third enclosing portion 43. The third enclosing portion 43 extends into the first sub-detection air channel 21, and the third enclosing portion 43 and the sealing body 42 jointly form the third sub-detection air channel 41. The third outer side wall 432 of the third enclosing portion 43 and the inner wall of the corresponding first sub-detection air channel 21 and the sealing body 42 jointly form a liquid collecting groove 14.

[0070] During liquid collection, the condensed liquid formed in the first sub-detection air channel 21 is collected in the liquid collecting groove 14. Thus, the condensed liquid in the first sub-detection air channel 21 can be effectively collected, and the condensed liquid in the first sub-detection air channel 21 can be effectively prevented from entering the liquid collecting space 325 through the third sub-detection air channel 41 and the second sub-detection air channel 31, and the influence of the condensed liquid generated in the first sub-detection air channel 21 on the airflow sensor 5 is further reduced.

[0071] Preferably, the liquid suction member 8 is arranged in the liquid collecting groove 14 and is used to suck and store the condensed liquid generated in the first sub-detection air channel 21. Thus, when the electronic atomization device 100 is in a side-down state, the condensed liquid in the liquid collecting groove 14 can be prevented from flowing into the liquid collecting space 325, and the influence of the condensed liquid generated in the first sub-detection air channel 21 on the airflow sensor 5 is further reduced.

[0072] Further, the liquid suction member 8 can be sponge, cotton or other materials that can absorb condensed liquid.

[0073] Further, referring to Figure 12 As shown, the third enclosing portion 43 has a third end face 431 and a third outer side wall 432. The third end face 431 faces away from the sealing body 42, and the third outer side wall 432 is connected between the third end face 431 and the sealing body 42. The third outer side wall 432 is at least partially inclined towards the inner wall of the corresponding first sub-detection air channel 21 from the connection position with the third end face 431 towards the sealing body 42, so that the condensed liquid generated on the third outer side wall 432 flows into the liquid collecting groove 14.

[0074] Further, referring to Figures 2-4 As shown, the atomization air channel comprises a first sub-atomization air channel 22, a second sub-atomization air channel 35 and a third sub-atomization air channel 46 which are sequentially connected. The suction member 2 forms the first sub-atomization air channel 22, the containing member 3 forms the second sub-atomization air channel 35, and the sealing member 4 forms the third sub-atomization air channel 46.

[0075] The one end of the first sub-atomization air channel 22 away from the second sub-atomization air channel 35 is communicated with the one end of the first sub-detection air channel 21 away from the second sub-detection air channel 31, and the one end of the first sub-detection air channel 21 and the first sub-atomization air channel 22 close to the sealing piece 4 is separated by the liquid suction piece 8. Therefore, the aerosol in the detection air channel can only be communicated at the one end of the suction nozzle piece 2 away from the sealing piece 4, and the amount of aerosol diffused into the detection air channel can be effectively controlled, and the amount of condensate formed in the detection channel is reduced.

[0076] Further, referring to FIGS. 1, 2 and 3, Figures 2-4 and Figure 12 As shown in FIGS. 1, 2 and 3, the sealing piece 4 further comprises a fourth blocking part 44 integrally formed with the sealing body 42. The fourth blocking part 44 extends into the first sub-atomization air channel 22, and the fourth blocking part 44 and the sealing body 42 jointly form the third sub-atomization air channel 46. The fourth blocking part 44 protrudes from the liquid collecting groove 14 and extends to the first sub-atomization air channel 22.

[0077] During liquid collection, the condensate formed in the first sub-atomization air channel 22 is gathered in the liquid collecting groove 14 and is sucked and locked by the liquid suction piece 8, so that the condensate in the first sub-atomization air channel 22 can be effectively prevented from flowing to the atomization piece 6 and blocking the atomization air channel.

[0078] Further, the sealing body 42 is configured to form a liquid collecting hole 45. The opening end of the liquid collecting hole 45 is communicated with the groove bottom of the liquid collecting groove 14, and the condensate gathered in the liquid collecting groove 14 will be preferentially collected in the liquid collecting hole 45. The liquid suction piece 8 covers the opening end of the liquid collecting hole 45, or the liquid suction piece 8 extends into the liquid collecting hole 45.

[0079] Further, referring to FIGS. 1, 2 and 3, Figures 2-4 As shown in FIGS. 1, 2 and 3, the sealing seat 7 and the containing piece 3 are configured to form an atomization cavity 15. The atomization piece 6 is arranged in the atomization cavity 15. The atomization air channel comprises the first sub-atomization air channel 22, the third sub-atomization air channel 46, the second sub-atomization air channel 35 and the atomization cavity 15 communicated in sequence. The aerosol formed by heating and atomization of the atomization piece 6 flows out in sequence through the atomization cavity 15, the second sub-atomization air channel 35, the third sub-atomization air channel 46 and the first sub-atomization air channel 22.

[0080] Further, the movement direction of the aerosol in the atomization cavity 15 is different from the movement direction of the aerosol in the second sub-atomization air channel 35, so that the aerosol needs to change the movement direction when moving from the atomization cavity 15 to the second sub-atomization air channel 35.

[0081] In one embodiment, the direction of the aerosol movement in the atomization cavity 15 is perpendicular to the direction of the aerosol movement in the second sub-atomization air passage 35.

[0082] Therefore, referring to Figures 2-4 In the first embodiment, the sealing seat 7 is provided with a first guide surface 71 corresponding to the atomization cavity 15 near the second sub-atomization air passage 35. The first guide surface 71 is used to guide the aerosol in the atomization cavity 15 to turn to the second sub-atomization air passage 35. The first guide surface 71 can be but is not limited to a slope, a curved surface, or other guide surface structures that can guide the aerosol in the atomization cavity 15 to smoothly change the flow direction to enter the second sub-atomization air passage 35.

[0083] In the second embodiment, the receiving member 3 is provided with a second guide surface 36 corresponding to the second sub-atomization air passage 35 at least near the atomization cavity 15. The second guide surface 36 is used to guide the aerosol in the atomization cavity 15 to turn to the second sub-atomization air passage 35. The first guide surface 71 can be but is not limited to a slope, a curved surface, or other guide surface structures that can guide the aerosol in the atomization cavity 15 to smoothly change the flow direction to enter the second sub-atomization air passage 35.

[0084] In the third embodiment, the sealing seat 7 is provided with a first guide surface 71 corresponding to the atomization cavity 15 near the second sub-atomization air passage 35, and the receiving member 3 is provided with a second guide surface 36 corresponding to the second sub-atomization air passage 35 at least near the atomization cavity 15. The first guide surface 71 and the second guide surface 36 are connected to each other, so that the aerosol in the atomization cavity 15 can smoothly flow to the second sub-atomization air passage 35.

[0085] Further, referring to Figures 2-4 In one embodiment, the cross section of the second sub-atomization air passage 35 along the flow direction of the aerosol gradually decreases, so as to effectively improve the flow rate of the aerosol entering the third sub-atomization air passage 46 and the first sub-atomization air passage 22 through the second sub-atomization air passage 35, and thus improve the user experience.

[0086] In the second embodiment, the cross section of the third sub-atomization air passage 46 along the flow direction of the aerosol gradually decreases, so as to effectively improve the flow rate of the aerosol entering the first sub-atomization air passage 22 through the third sub-atomization air passage 46, and thus improve the user experience.

[0087] In the third embodiment, the cross section of the second sub-atomization air passage 35 along the flow direction of the aerosol gradually decreases; and the cross section of the third sub-atomization air passage 46 along the flow direction of the aerosol gradually decreases.

[0088] In other embodiments, the first sub-atomization air passage 22 can also gradually decrease in cross-section along the flow direction of the aerosol.

[0089] Further, referring to Figures 2-4 As shown, the atomization member 6 is a ceramic heating element, which is sealingly connected at the liquid outlet of the liquid storage 12 by the sealing sleeve 10.

[0090] Further, the ceramic heating element includes a heating surface 61 and a liquid guide groove 62. The opening of the liquid guide groove 62 faces and communicates with the liquid storage 12, for increasing the contact area between the ceramic heating element and the aerosol substrate, thereby increasing the amount of liquid guided. The heating surface 61 faces the atomization cavity 15, for heating and atomizing the aerosol substrate to form aerosol, which is released into the atomization cavity 15.

[0091] Further, referring to Figures 2-4 As shown, the housing 1 is further provided with an air inlet hole 16, which communicates the mounting space 13 with the outside of the housing 1. The accommodation member 3 is provided with an air passing hole 37, which communicates the mounting space 13 with the atomization cavity 15. During suction, the external airflow flows into the atomization cavity 15 through the air inlet hole 16, the mounting space 13 and the air passing hole 37 in sequence, and then flows out through the second sub-atomization air passage 35, the third sub-atomization air passage 46 and the first sub-atomization air passage 22 in sequence after mixing with the generated aerosol in the atomization cavity 15.

[0092] Further, the external airflow flowing through the mounting space 13 can effectively cool the control circuit board 11 mounted in the mounting space 13.

[0093] In one embodiment, the airflow sensor 5 can send a feedback signal to the control circuit board 11 based on negative pressure sensing.

[0094] In another embodiment, the mounting space 13 also communicates with the second cavity 322, so that when the external airflow passes through the airflow sensor 5 after flowing through the air inlet hole 16 and the mounting space 13, the airflow sensor 5 is triggered to send a feedback signal to the control circuit board 11.
