Description

Technical Field

[0001] The present invention relates to the field of electronic atomization technology, and in particular to a power supply component and an electronic atomization device. Background Art

[0002] An electronic atomization device is a device that, when powered on, atomizes an aerosol-generating matrix to form an aerosol for the user to inhale; it is widely used in technical fields such as electronic cigarettes, medical treatment, and beauty.

[0003] An electronic atomization device typically includes an atomization assembly and a power supply assembly. The atomization assembly contains a liquid reservoir and an atomization core; the liquid reservoir is used to store the aerosol-generating matrix; the atomization core is used to atomize the aerosol-generating matrix. The power supply assembly houses a battery and an airflow sensor, which are electrically connected to the atomization core and the airflow sensor to power them. During use, when a user inhales through the nozzle of the atomization assembly, the resulting airflow triggers the airflow sensor, which in turn controls the battery to power the atomization core, causing it to atomize the aerosol-generating matrix.

[0004] However, when the aerosol generating matrix is ​​atomized, the liquid level in the liquid storage chamber storing the aerosol generating matrix drops, the air pressure decreases, and negative pressure is generated, which easily leads to the problem of poor liquid supply. At this time, the aerosol generating matrix cannot be quickly replenished to the atomizer core, causing the atomizer core to dry burn and overheat, which can easily cause damage to the atomizer core, and at this time, burnt smell and harmful substances will be produced. In order to solve the above technical problems, those skilled in the art have provided a ventilation channel connecting the liquid storage chamber with the external atmosphere in the atomizer assembly to replenish the liquid storage chamber.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0048] See also Figures 1 to 6 ;in, Figure 1 An exploded view of an electronic atomization device is provided for one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the electronic atomization device taken along the line AA; Figure 3 for Figure 1 A BB-section view of the electronic atomization device shown; Figure 4 A schematic structural diagram of an atomizing base under first-person perspective provided by an embodiment of the present application; Figure 5 A schematic structural diagram of an atomizing base under the second vision provided by an embodiment of the present application; Figure 6A schematic diagram of the structure of an atomizer base under the third perspective provided for an embodiment of the present application. In this embodiment, an electronic atomizer device is provided, which can be used in the technical fields of medical care, beauty, electronic cigarettes, home appliances, etc., and is used to heat and atomize an aerosol generating matrix to form an aerosol when powered on. The aerosol generating matrix can be a liquid medicine, smoke oil, or any other liquid suitable for electronic atomization formed by dispersing a certain medicine in a liquid solvent. The electronic atomizer device specifically includes a housing 1, an atomizer bracket 2, an atomizer core 3, an atomizer base 4, an airflow sensor 5, and a battery 6.

[0049] like Figures 1 to 3 As shown, the shell 1 includes a first shell 11 and a second shell 12. The first shell 11 has a first air inlet 111 and a receiving cavity with an opening at one end; the end of the receiving cavity facing away from the opening defines a battery receiving cavity, and the battery 6 is located in the battery receiving cavity. The atomizer base 4 is received in the first shell 11 through the opening of the first shell 11, and is located on the side of the battery receiving cavity facing the second shell 12; and the end wall of the atomizer base 4 facing the battery receiving cavity, that is, the end wall facing the battery 6 is sealedly connected to the inner wall surface of the first shell 11, and serves as the cavity wall of the battery receiving cavity. The cavity wall is defined as a partition 41 below. The partition 41 can isolate the battery 6 arranged in the battery receiving cavity from the liquid storage cavity 121 formed by the second shell 12, thereby preventing the aerosol generating matrix or aerosol condensate in the liquid storage cavity 121 from leaking into the battery receiving cavity and causing damage to the battery 6.

[0050] Specifically, the first housing 11 can be an integrally molded structure; of course, the first housing 11 can also be a hollow structure formed by snapping together front to back or left to right. The first housing 11 can also be made of a light-transmitting material to facilitate observation of the contents of the first housing 11. The light-transmitting material can be heat-resistant glass or plastic. Of course, the first housing 11 can also be made of a non-light-transmitting material, which is not specifically limited here.

[0051] The second housing 12 further includes a hollow cavity, a suction nozzle 120, and a first air outlet channel 122 (see FIG. Figure 2); the nozzle 120 is located at one end of the shell 1, and the second shell 12 is fixedly connected to the first shell 11 to achieve the non-detachable electronic atomization device, which can prevent the aerosol-generating matrix leaking when the electronic atomization device is disassembled from contaminating the user; and when the user is inhaling, it can reduce the proportion of the airflow from the gap between the first shell 11 and the second shell 12 in the formed airflow, thereby effectively improving the sensitivity of the airflow sensor 5. Specifically, the nozzle 120 is a part of the second shell 12, that is, the nozzle 120 and the second shell 12 are an integrally formed structure, and a snap-fit ​​groove may be provided on the first shell 11, and a snap-fit ​​buckle may be provided on the outer wall of the second shell 12. The first shell 11 and the second shell 12 can be snapped into the snap-fit ​​groove by the snap-fit ​​buckle to achieve a fixed connection between the two. Of course, the snap-fit ​​buckle can be provided on the first shell 11, and the snap-fit ​​groove can be provided on the second shell 12; or the first shell 11 and the second shell 12 can be fixed by other means such as welding. It is understandable that, in another embodiment, the suction nozzle 120 may be detachably connected to the second shell 12 .

[0052] The atomizing bracket 2 is located between the liquid storage chamber 121 and the battery receiving chamber, and cooperates with the atomizing base 4 to form an atomizing chamber. Figure 1 The atomizing bracket 2 is formed with a liquid inlet 21 communicating with the liquid storage chamber 121, a second air outlet channel 22 communicating with the first air outlet channel 122, an aerosol flow groove 23 communicating with the second air outlet channel 22 and the atomizing chamber, and a fixing groove 25 (see FIG. Figure 3 The fixing groove 25 is located on the end surface of the atomizer bracket 2 facing the battery receiving chamber. The atomizer core 3 is accommodated in the fixing groove 25 and covers the liquid inlet hole 21, so that the aerosol-generating matrix flowing out of the liquid storage chamber 121 through the liquid inlet hole 21 directly reaches the surface of the atomizer core 3. Then, when the atomizer core 3 is powered, the aerosol-generating matrix is ​​atomized to form an aerosol. The formed aerosol flows out through the aerosol flow groove 23, the second air outlet channel 22, and the first air outlet channel 122 in sequence.

[0053] In the specific embodiment, please refer to Figure 2 The atomizing base 4 is located between the liquid storage chamber 121 and the battery receiving chamber along its axial direction D. Figure 1 and Figure 4 The atomizing base 4 specifically includes an atomizing tank 42, a leakage collecting chamber 43, a sealing cover 433, a sensor accommodating chamber 44 and a first exhaust hole 422. Figures 1 to 3 As shown, the atomizer tank 42 is located on the side of the atomizer base 4 facing the liquid storage chamber 121, and the atomizer bracket 2 is specifically covered at one end of the atomizer tank 42 away from the battery receiving chamber and extends into the atomizer tank 42. The bottom of the atomizer bracket 2 cooperates with the bottom of the atomizer tank 42 to form an atomizer chamber. In a specific embodiment, as shown in FIG. Figure 6As shown, the bottom wall of the atomizing tank 42 is further formed with a liquid locking tank 421 for storing the aerosol generating substrate or aerosol condensate in the atomizing chamber. Figure 4 As shown, the first exhaust hole 422 is opened on the bottom wall of the atomizing groove 42 and is located between the atomizing groove 42 and the leakage collecting chamber 43; the first exhaust hole 422 is connected with the atomizing groove 42 and the leakage collecting chamber 43 respectively; and when the electronic atomizing device is placed vertically and the suction nozzle 120 is facing upward, that is, along the axial direction D of the atomizing base 4, the height of the opening of the first exhaust hole 422 connected to the atomizing groove 42 is higher than the height of the notch of the locking groove 421, so as to prevent the aerosol generating matrix or aerosol condensate in the locking groove 421 from leaking through the first exhaust hole 422.

[0054] like Figures 4 to 6 As shown, the leakage collection chamber 43 and the sensor accommodating chamber 44 are both located between the partition 41 and the atomizing tank 42. The leakage collection chamber 43 is used to collect the aerosol-generating substrate and aerosol condensate leaking from the first exhaust hole 422 in the atomizing tank 42, so as to prevent the leaked aerosol-generating substrate and aerosol condensate from entering the battery accommodating chamber and causing damage to the battery 6.

[0055] Specifically, such as Figure 3 and Figure 4 As shown, the opening of the leakage collection chamber 43 is arranged toward the inner side wall of the first shell 11, and the sealing cover 433 is provided at the opening of the leakage collection chamber 43 and elastically abuts against the opening of the leakage collection chamber 43 to seal the leakage collection chamber 43; in this way, after the atomization is completed, the remaining aerosol diffused into the leakage collection chamber 43 can be prevented from diffusing to other places and condensing, thereby better preventing the aerosol condensate from leaking. A second air inlet hole 4331 is provided on the sealing cover 433, the first end of the second air inlet hole 4331 is connected to the first air inlet hole 111, and the second air inlet hole 4331 extends in the radial direction of the atomizer base 4; the second end of the second air inlet hole 4331 is connected to the leakage collection chamber 43; in a specific embodiment, when the user inhales the aerosol, the external air flow enters the leakage collection chamber 43 through the first air inlet hole 111, the second air inlet hole 4331, and then enters the atomization chamber through the first exhaust hole 422.

[0056] Furthermore, if Figure 2 As shown, in order to better seal the leakage collection chamber 43, the electronic atomization device may further include a first sealing ring 7a and a second sealing ring 7b, both of which are sleeved on the outer peripheral surface of the atomization base 4, and the leakage collection chamber 43 is located between the first sealing ring 7a and the second sealing ring 7b, so as to further seal the leakage collection chamber 43 through the first sealing ring 7a and the second sealing ring 7b. Specifically, as shown in FIG. Figure 5As shown, a sealing groove 429a and a sealing groove 429b are opened on the outer wall of the atomizing base 4, and the first sealing ring 7a is clamped in the sealing groove 429a for fixation; the second sealing ring 7b is clamped in the sealing groove 429b for fixation.

[0057] In order to further improve the liquid locking effect of the leakage collection chamber 43, the aerosol-generating matrix or aerosol condensate is prevented from leaking out of the leakage collection chamber 43. Figure 7 , Figure 7 This is a schematic diagram of the structure of the atomizer base provided in another embodiment of the present application; a plurality of capillary grooves 431 may be further provided on the wall of the leakage collection chamber 43 to lock the liquid through the capillary force of the capillary grooves 431. The wall of the leakage collection chamber 43 may include a bottom wall and / or side walls. In another specific embodiment, see Figure 8 , Figure 8 This is a schematic diagram of the structure of the atomizer base provided in another embodiment of the present application; an adsorbent 432 may be further provided in the leakage collection chamber 43 to absorb the aerosol-generating matrix or aerosol condensate that enters the leakage collection chamber 43. The adsorbent 432 may be a liquid-absorbing material such as cotton cloth or a sponge.

[0058] See Figures 1 to 3 , the sensor accommodating cavity 44 is used to place the airflow sensor 5; compared with the existing solution, the airflow sensor 5 is installed on the atomizer base 4, rather than on the bracket for installing the battery 6, so the airflow sensor 5 is closer to the atomizer cavity, which can effectively improve the sensing sensitivity of the airflow sensor 5, and the overall structure is compact, which is conducive to the miniaturization of the electronic atomizer device and convenient for users to carry. In a specific embodiment, the cavity mouth of the sensor accommodating cavity 44 is arranged facing the inner wall of the first shell 11, and the airflow sensor 5 is detachably arranged in the sensor accommodating cavity 44; this facilitates the recycling of the airflow sensor 5, which is more environmentally friendly. Specifically, the radial direction of the airflow sensor 5 is inclined at a certain angle to the radial direction of the atomizer base 4, that is, the radial direction of the airflow sensor 5 is not parallel to the radial direction of the atomizer base 4; this can prevent the airflow sensor 5 from being soaked by the aerosol generating matrix or the aerosol condensate, thereby further protecting the airflow sensor 5. Among them, the inclination angle can be greater than 0° and less than or equal to 90°. As Figure 3 As shown, in a specific embodiment, the radial direction of the airflow sensor 5 is perpendicular to the radial direction of the atomizer base 4 .

[0059] In a specific embodiment, the linear distance between the leakage collection chamber 43 and the atomizer core 3 is not less than the linear distance between the sensor accommodating chamber 44 and the atomizer core 3. This allows aerosol condensate or aerosol-generating substrate to flow toward the leakage collection chamber 43 under the action of its own gravity when aerosol condensate or aerosol-generating substrate exists in the sensor accommodating chamber 44, thereby reducing the accumulation of aerosol condensate or aerosol-generating substrate in the sensor accommodating chamber 44, thereby protecting the airflow sensor 5 disposed in the sensor accommodating chamber 44. The linear distances between the leakage collection chamber 43 and the sensor accommodating chamber 44 and the atomizer core 3 are both measured along the axial direction D of the atomizer base 4, corresponding to the vertical distance between the side wall of the cavity away from the atomizer core 3 and the plane on which the atomizer core 3 lies.

[0060] In a specific embodiment, the leakage collection chamber 43 and the sensor accommodating chamber 44 are spaced apart along the circumferential direction of the atomizer base 4, and the straight-line distance between the two and the atomizer core 3 is the same, that is, the leakage collection chamber 43 and the sensor accommodating chamber 44 are arranged side by side along the radial direction of the atomizer base 4; this not only facilitates processing, but also makes the product structure compact and can reduce the product volume. For details, see Figure 4 and Figure 5 The bottom wall of the atomizing tank 42 is spaced apart from the partition 41 and connected by a baffle 45. The baffle 45 divides the space between the bottom wall of the atomizing tank 42 and the partition 41 into two parts. The first part serves as a leakage collection chamber 43, and the second part is used to accommodate a sensor accommodating chamber 44. The baffle 45 also serves as the side wall of the leakage collection chamber 43 and the bottom wall of the sensor accommodating chamber 44. It will be understood that in this embodiment, the straight-line distance between the leakage collection chamber 43 and the sensor accommodating chamber 44 and the atomizing core 3 refers to the perpendicular distance between the partition 41 and the plane where the atomizing core 3 is located.

[0061] In a specific embodiment, Figure 4 As shown, the baffle 45 is also provided with a second exhaust hole 451, which is connected to the leakage collection chamber 43 and the sensor accommodating chamber 44 and serves as an air pressure triggering channel for the airflow sensor 5 installed in the sensor accommodating chamber 44. Among them, the sensor accommodating chamber 44 is connected to the first exhaust hole 422 through the second exhaust hole 451 and the leakage collection chamber 43, and then connected to the atomization tank 42. Compared with the solution in which the first exhaust hole 422 directly connects the atomization tank 42 and the sensor accommodating chamber 44, it can not only trigger the airflow sensor 5 to work when the user inhales, but also prevent the aerosol generating substrate or aerosol condensate leaking through the first exhaust hole 422 from directly entering the sensor accommodating chamber 44, causing damage to the airflow sensor 5. Preferably, the first exhaust hole 422 extends along the axial direction D of the atomization base 4, and the second exhaust hole 451 extends along the radial direction of the atomization base 4, thereby preventing the leaked aerosol generating substrate or aerosol condensate from directly entering the sensor accommodating chamber 44.

[0062] Specifically, when the electronic atomization device is placed vertically, that is, along the axial direction D of the atomization base 4, the vertical distance between the second exhaust hole 451 and the plane where the atomization core 3 is located is less than the vertical distance between the bottom wall of the leakage collection chamber 43 (i.e., the partition 41) and the plane where the atomization core 3 is located; in this way, when the electronic atomization device is used, it is possible to effectively avoid the problem of aerosol-generating matrix or aerosol condensate collected in the leakage collection chamber 43 overflowing into the sensor accommodating chamber 44 through the second exhaust hole 451, thereby preventing the airflow sensor 5 from being damaged. Furthermore, the second exhaust hole 451 can be arranged close to the first exhaust hole 422; in this way, when air flows through the first exhaust hole 422, the airflow sensor 5 can be quickly triggered to work, thereby effectively improving the sensitivity of the airflow sensor 5.

[0063] In one embodiment, see Figure 4 and Figure 9 , Figure 9 A schematic diagram of the second exhaust hole and the connecting hole provided in one embodiment of the present application; the second exhaust hole 451 specifically includes a first exhaust section 451a and a second exhaust section 451b that are interconnected. The first exhaust section 451a is connected to the leakage collection chamber 43, and the second exhaust section 451b is connected to the sensor accommodating chamber 44; and the angle α formed by the first exhaust section 451a and the second exhaust section 451b is greater than 0° and less than 180°. Wherein, by making the second exhaust hole 451 include the first exhaust section 451a and the second exhaust section 451b set at a certain angle, the exhaust path of the second exhaust hole 451 can be extended, so that when the electronic atomization device is working, the aerosol diffused into the second exhaust hole 451 forms condensate in the second exhaust hole 451 as much as possible, thereby effectively reducing the damage rate of the airflow sensor 5 caused by the remaining aerosol diffusing to the sensor accommodating chamber 44. In a specific embodiment, the second exhaust section 451b is perpendicular to the first exhaust section 451a; and as Figure 5 and Figure 9 As shown, the second exhaust section 451 b continues to extend from one end facing away from the sensor accommodating cavity 44 and further forms a connecting hole 452 .

[0064] See also Figure 1 、 Figure 3 as well as Figures 10a to 10b ,in, Figure 10a A schematic structural diagram of a first vision sensor bracket provided in one embodiment of the present application; Figure 10b A schematic structural diagram of a second vision sensor bracket provided in one embodiment of the present application; Figure 11The electronic atomization device further includes a sensor bracket 8 , which is partially disposed within the sensor accommodating cavity 44 . The airflow sensor 5 is specifically detachably mounted on the sensor bracket 8 , so that the airflow sensor 5 can be detachably mounted within the sensor accommodating cavity 44 via the sensor bracket 8 .

[0065] like Figure 10a As shown, the sensor bracket 8 includes a sleeve portion 81 and a first connecting ear 82. Figure 3 As shown, the sleeve portion 81 is at least partially located in the sensor accommodating cavity 44, and as shown in FIG. Figures 10a to 11 As shown, the first end of the sleeve 81 is an open end, and the airflow sensor 5 is installed in the sleeve 81 through the open end; and the second end of the sleeve 81 has a blocking wall 812, and the blocking wall 812 is provided with a third exhaust hole 813, the third exhaust hole 813 is connected to the second exhaust section 451b of the second exhaust hole 451, so as to connect the airflow sensor 5 in the sleeve 81 and the second exhaust hole 451 through the third exhaust hole 813; at the same time, the blocking wall 812 can be used to limit the airflow sensor 5.

[0066] In a specific embodiment, Figure 11 As shown, the barrier wall 812 extends toward the wall of the sensor accommodating chamber 44 and is formed with at least two spaced-apart top posts 814. The barrier wall 812 abuts against the bottom wall of the sensor accommodating chamber 44 via the at least two top posts 814. The abutment of the top posts 814 against the bottom wall of the sensor accommodating chamber 44 allows the barrier wall 812 to be spaced apart from the sensor accommodating chamber 44. This not only ensures that the airway is not easily blocked, but also prevents aerosol-generating substrate or aerosol condensate that enters the sensor accommodating chamber 44 through the second exhaust hole 451 from directly contacting the airflow sensor 5 and damaging the airflow sensor 5. Figure 11 As shown, the barrier wall 812 can cooperate with the cavity wall and side wall of the sensor accommodating cavity 44 to form an air pressure cavity 815. The air pressure cavity 815 can not only store part of the aerosol generating substrate or aerosol condensate entering the sensor accommodating cavity 44, but also because the volume of the air pressure cavity 815 is relatively small, generally 20 cm 3 -200cm 3 Therefore, as long as the air pressure in the air pressure chamber 815 changes slightly, it can be sensed, thereby effectively avoiding the problem of the airflow sensor 5 being mistakenly believed to be damaged due to not receiving the trigger signal, and effectively improving the sensitivity of the airflow sensor 5.

[0067] like Figure 10a and Figure 10bAs shown, the first end of the first connecting ear 82 is connected to the sleeve body 81, and the second end of the first connecting ear 82 is provided with a fixing post 821 on the side surface facing the atomizer base 4. The fixing post 821 is plugged into the connecting hole 452 to achieve the fixation of the first connecting ear 82 to the atomizer base 4. The plug-in fixation of the fixing post 821 and the connection not only stabilizes the connection, but also simplifies the manufacturing process.

[0068] In one embodiment, please combine Figure 5 and Figure 10a The atomizer base 4 is further formed with a connecting groove 441, which is located on the first side of the sensor accommodating chamber 44, and a connecting hole 452 is located on the second side of the sensor accommodating chamber 44. The first side of the sensor accommodating chamber 44 and the second side of the sensor accommodating chamber 44 are respectively located on opposite sides of the sensor accommodating chamber 44. The sensor bracket 8 also includes a second connecting ear 83, a first end of the second connecting ear 83 is connected to the sleeve portion 81, and a second end of the second connecting ear 83 is plugged and connected to the connecting groove 441. In a specific embodiment, a card plate 441a is provided on the groove wall of the connecting groove 441, and the second connecting ear 83 is provided with a card slot 831. The card plate 441a is inserted into the card slot 831 to achieve the fixation of the second connecting ear 83 and the atomizer base 4, thereby increasing the connection reliability of the sensor bracket 8 and the atomizer base 4. Specifically, there are two card plates 441a, which are spaced apart. The slot wall of the card slot 831 elastically abuts against each card plate 441a to further enhance the connection reliability and avoid the problem of damage to the second connecting ear 83 or the connecting slot 441 caused by rigid contact between the slot wall of the card slot 831 and the card plate 441a.

[0069] In one embodiment, if Figures 4 to 6 At least one ventilation cavity 46 is formed on the atomizing base 4, and a ventilation hole 24 is provided at a position of the atomizing bracket 2 corresponding to the ventilation cavity 46 (see Figure 1), the ventilation through-hole 24 connects the ventilation chamber 46 with the liquid storage chamber 121, so that the liquid storage chamber 121 maintains an air pressure balance with the outside world through the ventilation through-hole 24, which is convenient for liquid discharge. The ventilation chamber 46 extends along the axial direction D of the atomizer base 4, and the cavity mouth of the ventilation chamber 46 is located at the end face of the atomizer base 4 and is arranged facing the liquid storage chamber 121, and is used to collect the aerosol generating matrix leaked from the ventilation through-hole 24, to prevent it from clogging the ventilation through-hole 24 and affecting the ventilation effect, and to avoid these aerosol generating matrices from further leaking to the battery 6 or the airflow sensor 5, thereby causing damage to the battery 6 or the airflow sensor 5. In a specific embodiment, the cross-section of the ventilation chamber 46 along the axial direction of the atomizer base 4 is plate-shaped, and the length dimension of the ventilation chamber 46 along the axial direction D of the atomizer base 4 is greater than the width dimension perpendicular to the axial direction D of the atomizer base 4. Specifically, the cross section of the ventilation cavity 46 along the radial direction of the atomizer base 4 may be crescent-shaped, rectangular, or elliptical, etc.; the ventilation cavity 46 has a large storage capacity for aerosol-generating substrates or condensate.

[0070] In a specific embodiment, if Figure 6 As shown, the number of ventilation chambers 46 is specifically two, and the two ventilation chambers 46 are relatively arranged on both sides of the atomizing groove 42 along the radial direction of the atomizing base 4; and a first ventilation hole 461 is provided on the side wall of each ventilation chamber 46 facing away from the atomizing groove 42, and the first ventilation hole 461 connects the ventilation chamber 46 with the outside atmosphere. It can be understood that the outside atmosphere refers to the atmosphere outside the electronic atomizing device. In a specific embodiment, when the electronic atomizing device is placed vertically and the mouthpiece 120 is facing upward, that is, along the axial direction D of the atomizing base 4, the height of the position where the first ventilation hole 461 is located is higher than the height of the position where the bottom wall of the ventilation chamber 46 is located; in this way, when the electronic atomizing device is placed vertically, the aerosol generating matrix or aerosol condensate stored in the ventilation chamber 46 is prevented from leaking through the first ventilation hole 461, resulting in the loss of the battery 6 or the airflow sensor 5.

[0071] Specifically, the atomizing base 4 and the first shell 11 or the second shell 12 cooperate to form a first ventilation channel and / or a second ventilation channel. Figure 4 and Figure 5As shown, in a specific embodiment, a first ventilation groove 425 and a second ventilation groove 426 are formed on the outer wall of the atomizer base 4, and the first ventilation groove 425 is in contact with and cooperates with the inner wall surface of the first shell 11 or the second shell 12 to form a first ventilation channel, and the second ventilation groove 426 is in contact with and cooperates with the inner wall surface of the first shell 11 or the second shell 12 to form a second ventilation channel; the following embodiments are all taken as an example. Of course, in other embodiments, the first ventilation groove 425 and / or the second ventilation groove 426 can also be opened on the inner wall surface of the first shell 11, or the first ventilation groove 425 and / or the second ventilation groove 426 can also be opened on the inner wall surface of the second shell 12; or, the first shell 11 or the second shell 12 are both provided with ventilation grooves at positions corresponding to the atomizer base 4, and the ventilation grooves on the first shell 11 or the second shell 12 cooperate with the ventilation grooves on the outer wall of the atomizer base 4 to form a ventilation channel. This application is not limited to this.

[0072] In one embodiment, see Figure 12 and Figure 13 ; Figure 12 An exploded view of an electronic atomization device is provided for another embodiment of the present application; Figure 13 for Figure 12 The CC sectional view of the electronic atomization device shown; the first end of the first ventilation groove 425 is connected to the first ventilation hole 461, and the second end of the first ventilation groove 425 is connected to the outside atmosphere through the air inlet on the shell 1; the first end of the second ventilation groove 426 is connected to the first ventilation hole 461, and the second end of the second ventilation groove 426 is connected to the outside atmosphere through the air inlet on the shell 1; so that the first ventilation hole 461 can be connected to the outside atmosphere through the first ventilation groove 425 and / or the second ventilation groove 426; in this way, even if one of the first ventilation groove 425 and the second ventilation groove 426 is blocked, the first ventilation hole 461 can also be ventilated through the other ventilation groove, reducing the probability of blockage of the ventilation channel of the liquid storage chamber 121. At the same time, the second end of the first ventilation groove 425 is directly connected to the outside atmosphere, and the second end of the second ventilation groove 426 is also directly connected to the outside atmosphere. Compared with the scheme in which the second end of the ventilation groove is connected to the atomization chamber, the scheme in which the aerosol in the atomization chamber is connected to the outside atmosphere can avoid diffusing the aerosol in the atomization chamber to the ventilation groove or the ventilation hole, causing the ventilation channel of the liquid storage chamber 121 to be blocked.

[0073] The air inlet on the housing 1 may be the same through hole as the first air inlet hole 111, or may be a through hole different from the first air inlet hole 111. Figure 12As shown, first housing 11 has first ventilation inlet slots 112 at the second ends corresponding to first ventilation slots 425 and second ventilation slots 426, respectively. Second housing 12 has second ventilation inlet slots 123 at positions corresponding to first ventilation inlet slots 112. First ventilation inlet slots 112 communicate with the outside atmosphere, while second ventilation inlet slots 123 communicate with the first ventilation slots 425 or the second ventilation slots 426. This allows first ventilation slots 425 and second ventilation slots 426 to communicate with the outside atmosphere via corresponding second ventilation inlet slots 123 and first ventilation inlet slots 112. The first ventilation inlet slots 112 and second ventilation inlet slots 123 together define an air inlet on housing 1.

[0074] In another embodiment, if Figure 3 、 Figure 5 as well as Figure 7 As shown, the atomizer base 4 also includes a second ventilation hole 427 and a third ventilation hole 428. The first end of the second ventilation hole 427 is connected to the second end of the first ventilation groove 425, and the second end of the second ventilation hole 427 is connected to the atomizing chamber; the first end of the third ventilation hole 428 is connected to the second end of the second ventilation groove 426, and the second end of the third ventilation hole 428 is connected to the atomizing chamber. That is, the second ventilation groove 426 of this embodiment is connected to the outside atmosphere through the atomizing chamber. In this way, during the process of atomizing the aerosol-generating matrix by the atomizing core 3, even if part of the aerosol diffuses into the first ventilation groove 425 or the second ventilation groove 426 to form aerosol condensate, the air pressure in the atomizing chamber gradually increases, and the negative pressure is formed in the liquid storage chamber 121 as the aerosol-generating matrix continues to flow out. Under the action of this pressure difference, the aerosol condensate in the first ventilation groove 425 or the second ventilation groove 426 gradually flows into the ventilation chamber 46, thereby effectively preventing the aerosol condensate from clogging the first ventilation groove 425 or the second ventilation groove 426, or preventing the ventilation from being delivered quickly and affecting the ventilation effect. Specifically, an inner ventilation groove (not shown in the figure) is formed between the side wall of the atomizing bracket 2 and the inner wall of the atomizing groove 42, and the second ventilation hole 427 and the third ventilation hole 428 are respectively connected to the atomizing chamber through the inner ventilation groove.

[0075] In this embodiment, Figure 5 As shown, the first ventilation groove 425 is located on the first side of the first ventilation hole 461, and the second ventilation groove 426 is located on the second side of the first ventilation hole 461. The first side of the first ventilation hole 461 and the second side of the first ventilation hole 461 are arranged opposite to each other. This can prevent the aerosol condensate in the first ventilation groove 425 and the second ventilation groove 426 from interfering with each other.

[0076] Further, see Figure 14 , Figure 14This is an orthographic projection of the first ventilation hole 461, the second ventilation hole 427, the third ventilation hole 428, the ventilation groove and the atomizer core on the AA plane provided in an embodiment of the present application; in order to further promote the aerosol condensate in the first ventilation groove 425 and / or the second ventilation groove 426 to flow into the ventilation chamber 46, the height of the second ventilation hole 427 and / or the third ventilation hole 428 along the axial direction D of the atomizer base 4 can be made higher than the height of the first ventilation hole 461, so that the aerosol condensate in the first ventilation groove 425 and / or the second ventilation groove 426 can flow into the ventilation chamber 46 through the first ventilation hole 461 under the action of its own gravity.

[0077] Specifically, such as Figure 14 As shown, the height of the second ventilation hole 427 and / or the third ventilation hole 428 along the axial direction D of the atomizer base 4 is higher than the height of the bottom wall of the atomizer chamber, that is, higher than the bottom wall of the atomizer groove 42, so as to prevent the aerosol-generating substrate or aerosol condensate in the atomizer chamber from flowing into the second ventilation hole 427 and / or the third ventilation hole 428. Furthermore, the height of the second ventilation hole 427 along the axial direction D of the atomizer base 4 is the same as the height of the third ventilation hole 428 along the axial direction D of the atomizer base 4; that is, the first ventilation hole 461 and the second ventilation hole 427 are located at the same radial position of the atomizer base 4; and the second ventilation hole 427 and the third ventilation hole 428 are arranged opposite each other along the radial direction of the atomizer base 4.

[0078] In this embodiment, Figure 14 As shown, the orthographic projection of the atomizer core 3 on the cavity wall of the atomizer groove 42 facing the ventilation cavity 46, that is, the orthographic projection of the atomizer core 3 on the AA plane is at least partially located between the second ventilation hole 427 and the third ventilation hole 428. In this way, ventilation can be driven quickly according to the pressure change when the atomizer core 3 is working. Specifically, the second ventilation hole 427 and the third ventilation hole 428 are located at the same radial position as the side surface of the atomizer core 3 facing the bottom wall of the atomizer groove 42; that is, along the axial direction D of the atomizer base 4, the height of the position of the second ventilation hole 427 and the third ventilation hole 428 is the same as the height of the position of the side surface of the atomizer core 3 facing the bottom wall of the atomizer groove 42. In this way, ventilation can be further driven quickly according to the pressure change when the atomizer core 3 is working.

[0079] In the specific embodiment, please refer to Figure 1 and Figure 2 The electronic atomization device further includes an electrode 91, an electronic wire 92, a sealing cover 93, a sealing seat 94, and a third sealing ring 7c. The electrode 91 is fixed in the atomization groove 42 of the atomization base 4 and abuts against the atomization core 3. The electrode 91 is connected to the battery 6 through the electronic wire 92 to supply power to the atomization core 3. Specifically, Figure 2As shown, the electrode 91 includes a conductive column and a blocking ring; the first end of the conductive column is connected to the bottom wall of the atomizing groove 42, and the second end of the conductive column is in contact with the atomizing core 3; the blocking ring is arranged around the outer circumference of the conductive column and is connected to the conductive column; and is located on the bottom wall of the atomizing groove 42, for limiting the electrode 91 to avoid poor contact between the electrode 91 and the atomizing core 3.

[0080] like Figure 1 、 Figure 2 and Figure 15 , Figure 15 The sealing cover 93 is provided on the side of the atomizer support 2 facing the liquid storage chamber 121, and wraps the end of the atomizer base 4 facing the liquid storage chamber 121, which is used to prevent the aerosol-generating matrix in the liquid storage chamber 121 from leaking into the ventilation chamber 46 and improve the sealing performance of the atomizer chamber. Specifically, the sealing cover 93 is made of elastic material. Figure 15 As shown, the sealing cover 93 includes an end wall 931 and an annular side wall 932; wherein the side wall 932 is sleeved on the outer peripheral surface of the atomizer bracket 2 and the atomizer base 4; the end wall 931 is located at the end surface of the side wall 932 and is connected to the side wall 932. The end wall 931 is covered at the end surface of the atomizer bracket 2 facing the liquid storage chamber 121 and covers the opening of the ventilation hole 24 to prevent the aerosol-generating matrix in the liquid storage chamber 121 from flowing out of the ventilation hole 24 to the ventilation chamber 46. It can be understood that when a negative pressure is formed in the liquid storage chamber 121, the elastic sealing cover 93 is lifted toward the liquid storage chamber 121 under the action of the pressure difference, so that the ventilation hole 24 is connected to the liquid storage chamber 121 and ventilation is performed.

[0081] Specifically, the sealing cover 93 has a first opening 933 at a position corresponding to the liquid inlet 21 of the atomizer bracket 2 to ensure that the aerosol-generating substrate in the liquid storage chamber 121 can smoothly enter the liquid inlet 21. The sealing cover 93 has a second opening 934 corresponding to the second air outlet channel 22 of the atomizer bracket 2 to ensure that the first air outlet channel 122 can communicate with the second air outlet channel 22 through the second opening 934.

[0082] like Figures 1 to 3 As shown, the sealing seat 94 is arranged in the fixing groove 25 and wraps the circumferential side of the atomizer core 3, and is located between the atomizer core 3 and the liquid inlet 21, and is used to prevent the aerosol-generating matrix flowing out of the liquid inlet 21 from directly flowing out of the gap between the atomizer core 3 and the atomizer bracket 2 into the atomizer chamber. Specifically, as Figure 1 As shown, the sealing seat 94 is provided with a liquid guide hole 941 at a position corresponding to the liquid inlet hole 21 to guide the aerosol-generating matrix flowing out of the liquid inlet hole 21 to the surface of the atomizing core 3. Figure 1 As shown, combined with Figure 16 , Figure 16This is a schematic diagram of the abutment between the sealing seat and the atomizer bracket. The end surface of the sealing seat 94 facing away from the battery compartment is provided with a plurality of spaced elastic abutments 942. The elastic abutments 942 elastically abut against the walls of the fixing groove 25. By providing the elastic abutments 942, when the atomizer core 3 is installed in the atomizer bracket 2, the elastic abutments 942 can abut relatively smoothly against the walls of the fixing groove 25. This allows the elastic deformation of the sealing seat 94 in the area located near the elastic abutments 942 to be more uniform, thus preventing the atomizer core 3 in the sealing seat 94 from cracking due to uneven force.

[0083] The third sealing ring 7c is embedded in the sealing groove 429c on the outer periphery of the atomizer base 4 and is located between the liquid storage chamber 121 and the leakage collection chamber 43 along the axial direction D of the atomizer base 4 to prevent the aerosol-generating substrate and / or aerosol condensate in the liquid storage chamber 121 from leaking into the battery accommodating chamber or the sensor accommodating chamber 44 through the gap between the atomizer base 4 and the first housing 11. The first sealing ring 7a, the second sealing ring 7b, the third sealing ring 7c, the sealing cover 93, and the sealing seat 94 can all be made of materials such as silicone or rubber.

[0084] Of course, in a specific embodiment, the electronic atomization device also includes other existing structures such as fixing parts and sealing parts in the existing electronic atomization device. For details, please refer to the existing technology, and the same or similar technical effects can be achieved, which will not be repeated here.

[0085] The electronic atomization device provided in this embodiment, by providing a leakage collection chamber 43, which is connected to the atomizer core 3 through the first exhaust hole 422, can use the leakage collection chamber 43 to store leaked aerosol-generating substrate and / or aerosol condensate, thereby preventing the aerosol-generating substrate and / or aerosol condensate from leaking into the battery 6 of the power supply assembly or the airflow sensor 5 and damaging the battery 6 or the airflow sensor 5. At the same time, by ensuring that the straight-line distance between the leakage collection chamber 43 and the atomizer core 3 is no less than the straight-line distance between the sensor accommodating chamber 44 and the atomizer core 3, when aerosol condensate or aerosol-generating substrate is present in the sensor accommodating chamber 44, the aerosol condensate or aerosol-generating substrate can flow toward the leakage collection chamber 43 due to gravity, reducing the accumulation of aerosol condensate or aerosol-generating substrate in the sensor accommodating chamber 44, thereby protecting the airflow sensor 5 disposed therein. Furthermore, by making the airflow sensor 5 detachable and disposed within the sensor accommodating chamber 44, the airflow sensor 5 can be easily recycled, which is more environmentally friendly. Furthermore, by making the end wall of the atomizer base 4 facing the battery accommodating chamber sealedly connected to the first housing 11 and serving as the wall of the battery accommodating chamber, the battery 6 disposed within the battery accommodating chamber can be isolated from the liquid storage chamber 121 by this wall, preventing the aerosol-generating substrate or aerosol condensate within the liquid storage chamber 121 from leaking into the battery accommodating chamber and damaging the battery 6. Furthermore, by making the sensor bracket 8 abut against the bottom wall of the sensor accommodating chamber 44 through the top column 814, not only can the airway be ensured to be not easily blocked, but also the problem of the aerosol generating matrix or aerosol condensate directly contacting the airflow sensor 5 and damaging the airflow sensor 5 can be avoided; at the same time, the blocking wall 812 can cooperate with the cavity wall and side wall of the sensor accommodating chamber 44 to form an air pressure chamber 815, which can not only store part of the aerosol generating matrix or aerosol condensate entering the sensor accommodating chamber 44, but also can effectively avoid the problem of the airflow sensor 5 being mistakenly thought to be damaged due to not receiving the trigger signal, thereby effectively improving the sensitivity of the airflow sensor 5.

[0086] In one embodiment, please continue to refer to Figures 1 to 16A power supply assembly is also provided, which is used to connect to the atomizer assembly.

The first housing 11 defines a battery receiving chamber; the battery 6 is located within the battery receiving chamber; the atomizer base 4 is housed within the first housing 11 and is located between the liquid storage chamber 121 and one side of the battery receiving chamber; the atomizer base 4 includes an atomizer tank 42, a first exhaust hole 422, a leaked liquid collection chamber 43, a sensor receiving chamber 44, a ventilation chamber 46, and a first ventilation hole 461. The atomizing tank 42 is used to cooperate with the atomizing assembly to form an atomizing chamber; the first exhaust hole 422 is located between the atomizing tank 42 and the leakage collection chamber 43 and is connected to the atomizing tank 42 and the leakage collection chamber 43; the straight-line distance between the leakage collection chamber 43 and the atomizing tank 42 is not less than the straight-line distance between the sensor accommodating chamber 44 and the atomizing tank 42; the cavity opening of the sensor accommodating chamber 44 is arranged to face the inner wall of the first shell 11; the airflow sensor 5 is detachably arranged in the sensor accommodating chamber 44; and the battery 6 is located in the battery accommodating chamber. The straight-line distances between the leakage collection chamber 43 and the sensor accommodating chamber 44 and the atomizing tank 42 are both perpendicular to the plane where the partition 41 and the bottom wall of the atomizing tank 42 are located. The ventilation chamber 46 extends along the axial direction D of the atomizer base 4, and the cavity mouth of the ventilation chamber 46 is located at the end face of the atomizer base 4 and is arranged facing the liquid storage chamber 121; the first ventilation hole 461 is located at the cavity wall of the ventilation chamber 46 and is connected to the ventilation chamber 46 and the outside atmosphere; when the power supply assembly is placed vertically and the suction nozzle 120 is facing upward, the height of the position of the first ventilation hole 461 is higher than the height of the bottom wall of the ventilation chamber 46.

[0087] Specifically, the specific structure and function of the first housing 11, battery 6, atomizer base 4, airflow sensor 5, and sensor bracket 8 involved in this embodiment can refer to the specific structure and function of the first housing 11, battery 6, atomizer base 4, airflow sensor 5, and sensor bracket 8 in the electronic atomizer device provided in the above embodiment, and can achieve the same or similar technical effects, which will not be repeated here. Of course, the power supply assembly also includes other components that cooperate with the atomizer base 4, such as the sealing cover 433, the first to third sealing rings 7c, etc., which can be specifically referred to the above-mentioned related text description and will not be repeated here.

[0088] The atomizer assembly includes a second shell 12, an atomizer bracket 2, an atomizer core 3, a sealing cover 433, an atomizer seat and an electrode 91; wherein, the specific structure and function of the second shell 12, the atomizer bracket 2, the atomizer core 3, the atomizer sleeve, the atomizer seat and the electrode 91 can refer to the specific structure and function of the second shell 12, the atomizer bracket 2, the atomizer core 3, the sealing cover 433, the atomizer seat and the electrode 91 in the electronic atomizer device provided in the above embodiment, and can achieve the same or similar technical effects, which will not be repeated here.

[0089] The power supply assembly provided in this embodiment, by providing a ventilation chamber 46 communicating with the liquid storage chamber 121 and a first ventilation hole 461 communicating with the ventilation chamber 46 and the outside atmosphere, not only ventilates the liquid storage chamber 121 to ensure pressure balance within the liquid storage chamber 121 and facilitate liquid discharge, but also utilizes the ventilation chamber 46 to collect aerosol-generating substrate leaking from the liquid storage chamber 121, preventing the leaked aerosol-generating substrate from clogging the ventilation hole and affecting the ventilation effect, and further preventing the leaked aerosol-generating substrate from further leaking into the battery 6 or the airflow sensor 5, thereby damaging the battery or airflow sensor 5. Furthermore, when the electronic atomizer device is placed vertically, the height of the first ventilation hole 461 is higher than the height of the bottom wall of the ventilation chamber 46, thereby preventing the aerosol-generating substrate stored in the ventilation chamber 46 from flowing out of the first ventilation hole 461. In addition, by providing a sealing cover 93 and positioning the sealing cover 93 at the end of the atomizer base 4 facing the liquid storage chamber 121, the negative pressure in the liquid storage chamber 121 can prevent the aerosol-generating matrix in the liquid storage chamber 121 from flowing into the ventilation chamber 46 within a certain range, thereby avoiding damage to the battery 6 or the airflow sensor 5, thereby effectively extending the service life of the electronic atomizer device and saving resources.
