In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods.

[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that those skilled in the art can easily see. Therefore, the order in the specification and the drawings is only for the purpose of clearly describing a certain embodiment, and does not mean that it is the necessary order, unless otherwise stated that a certain order must be followed.

[0029] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. The "connection" and "coupling" in this application include direct and indirect connections (couplings) unless otherwise specified.

[0030] Please refer to Figures 1-7 In an embodiment of the present application, an atomization device is provided for heating and atomizing liquid into aerosol that can be inhaled by a user. For example, the atomization device heats and atomizes liquid into aerosol that can be inhaled by a user. The atomization device includes a liquid storage assembly 10, an atomization module 20, and an adapter 60.

[0031] The atomization channel 10a is formed in the liquid storage assembly 10. The atomization module 20 is at least partially disposed in the atomization channel 10a. The adapter 60 is sleeved with the end of the liquid storage assembly 10. The adapter 60 is tubular. The adapter 60 is provided with a partition plate 61. The partition plate 61 divides the adapter 60 into two spaces spaced in the axial direction. The partition plate 61 is provided with a ventilation hole 62. The ventilation hole 62 is in communication with the atomization channel 10a. The partition plate 61 is provided with a baffle 661 on the end surface away from the liquid storage assembly 10. The baffle 661 and the inner wall of the adapter 60 cooperatively wrap the ventilation hole 62. The baffle 661 encloses the airflow channel 60a in communication with the ventilation hole 62. The airflow channel 60a has two ends in the direction perpendicular to the axial direction of the adapter 60, which form a first airflow opening 60b and a second airflow opening 60c, respectively. The size of the first airflow opening 60b is larger than that of the second airflow opening 60c. The second airflow opening 60c is in communication with the airflow switch 80. That is, the position of the airflow switch 80 corresponds to the position of the second airflow opening 60c, or the second airflow opening 60c is arranged on the side close to the airflow switch 80.

[0032] The atomizing device in the above embodiment is adopted, and the baffle 661 is arranged on the partition plate 61 of the adapter 60, is located at an end face of the partition plate 61 away from the liquid storage assembly 10, and cooperates with the inner wall of the adapter 60 to surround the air hole 62. The baffle 661 surrounds to form an air flow channel 60a in communication with the air hole 62. Two ends of the air flow channel 60a form a first air passage 60b and a second air passage 60c, respectively. The size of the first air passage 60b is larger than that of the second air passage 60c, and the second air passage 60c is used in communication with the air flow switch 80. In this way, during the back blowing test, the mist flows reversely to the air hole 62 through the atomizing channel 10a, and then flows to the air flow channel 60a through the air hole 62. The size of the second air passage 60c is relatively small, which can reduce the flow amount of the mist at this position, that is, the amount of mist flowing to the air flow switch 80 connected with the second air passage 60c, thereby improving the corrosion phenomenon of the air flow switch 80 and prolonging the service life of the air flow switch 80. Similarly, the user subsequently uses the atomizing device, and the amount of mist flowing to the air flow switch 80 can be reduced through the second air passage 60c with a smaller size, thereby effectively prolonging the service life of the atomizing device and improving the product quality of the atomizing device.

[0033] Specifically, the baffle 661 is configured as two. The two baffles 661 are distributed on the two sides in the radial direction of the air hole 62, and the air flow channel 60a is formed between the two baffles 661. The air flow channel 60a is provided with a surrounding plate 67 at any one end, and the second air passage 60c is formed between the surrounding plate 67 and the baffle 661. The air flow channel 60a is provided with a surrounding plate 67 at any one end, and the second air passage 60c is formed between the surrounding plate 67 and the baffle 661. The end of the air flow channel 60a without the surrounding plate 67 forms the first air passage 60b through the space between the two baffles 661. The size of the first air passage 60b is relatively larger than that of the second air passage 60c. In this way, during the back blowing test, the mist flows reversely to the air hole 62 through the atomizing channel 10a, and then flows to the air flow channel 60a through the air hole 62. The surrounding plate 67 at the end of the air flow channel 60a can intercept part of the mist, and the second air passage 60c with a smaller size can also reduce the amount of mist passing through, so that the mist flows to the first air passage 60b as much as possible, thereby reducing the amount of mist flowing to the air flow switch 80, improving the corrosion phenomenon of the air flow switch 80, and prolonging the service life of the air flow switch 80.

[0034] The number and quantity of the surrounding plates 67 are not specifically limited in the application, for example, as shown in Figure 4As shown, one baffle 67 is arranged at one end of the airflow switch 80, the baffle 67 and the baffle plate 661 are in one-piece structure, one side of the baffle 67 is connected with the baffle plate 661, and the other side of the baffle 67 is opposite to the gap between the other baffle 67, thereby forming the second airflow passage 60c. Alternatively, for example, two baffle plates 67 are arranged at the end of the airflow passage 60a, the second airflow passage 60c can be formed between the two baffle plates 67, or even the two baffle plates 67 are arranged at intervals with the baffle plate 661, and the second airflow passage 60c can also be formed between the baffle plate 661 and the baffle plate 67. The second airflow passage 60c is arranged to reduce the amount of mist when the mist flows in the reverse direction, and at the same time, a small amount of gas is allowed to pass through, so that the user can detect the pressure change when sucking the atomization device, and the normal use of the airflow switch 80 is not affected.

[0035] In other embodiments, in addition to the gap between the plates forming the second airflow passage 60c, the baffle plate 67 can be connected with the baffle plates 661 on both sides, but a plurality of small hole structures (for example, holes with a diameter of 1 mm) are arranged on the baffle plate 67 to form the second airflow passage 60c, or alternatively, a mesh material structure is arranged at the end of the airflow passage 60a, for example, a sponge block is arranged at the end of the airflow passage 60a, which can block and adsorb the mist flowing to this place, and also facilitate the subsequent use of the atomization device, so that there is airflow passing through this place, thereby playing the role of the airflow switch 80.

[0036] Please refer to Figure 1 and Figure 2 In the embodiment of the present application, the liquid storage assembly 10 includes a liquid storage cup 11, a top sealing cover 12, a bottom sealing cover 13, and a liquid storage member 14. The liquid storage cup 11 is tubular, the top sealing cover 12 and the bottom sealing cover 13 are tightly fitted and connected to the two ends of the liquid storage cup 11, and the liquid storage cup 11, the top sealing cover 12, and the bottom sealing cover 13 form a relatively closed liquid storage cavity. The liquid storage member 14, such as liquid storage cotton, is arranged in the liquid storage cavity, and the liquid storage cotton is used to absorb and store the atomization liquid. The liquid storage cotton forms an atomization passage 10a.

[0037] The atomization module 20 includes an atomization tube, a liquid guide member, a heating member, and a lead wire. The atomization tube is fixed in the atomization passage 10a. At least part of the liquid guide member is fixed in the atomization tube. The liquid guide member is in communication or contact with the liquid storage member 14. The liquid guide member is used to absorb and conduct the atomization liquid on the liquid storage member 14. The liquid guide member is, for example, a liquid guide ceramic or a liquid guide cotton. The heating member is fixed on the liquid guide member in the atomization tube. The heating member is connected with one end of the lead wire. The heating member is used to heat the atomization liquid on the liquid guide member after being electrified.

[0038] The bottom sealing cover 13 is provided with a butt joint column 131 at one end thereof facing the heating element, a passage in the butt joint column 131 is communicated with the atomizing pipe, and a first lead hole 132 is formed in the end face of the bottom sealing cover 13 at two sides of the butt joint column 131, so as to allow two leads connected with the heating element to pass through the first lead holes 132 respectively.

[0039] The atomizing device further comprises a first liquid suction element 30, a suction nozzle 40 and a suction nozzle plug 50. The suction nozzle 40 is connected to the end of the liquid storage cup 11 of the top sealing cover 12, for example, the suction nozzle 40 is snap connected to the liquid storage cup 11. The first liquid suction element 30 is fixed in the groove on the side of the top sealing cover 12 facing the suction nozzle 40. The suction nozzle plug 50 is sleeved with the end of the suction nozzle 40 away from the top sealing cover 12. It can be understood that the reverse flow refers to the flow of the mist generated after the atomizing liquid is heated away from the end of the suction nozzle 40.

[0040] The specific structural design of the liquid storage assembly 10 and the atomizing module 20 is only an exemplary enumeration for more clearly and completely describing the structure of the atomizing device of the present application, and should not be understood as a limitation of the present application. In fact, as long as the liquid storage assembly 10 and the atomizing module 20 meet the requirements, they can be used, for example, in other embodiments, the liquid storage cup 11 and the bottom sealing cover 13 are integrated, and the liquid storage cup 11 and the bottom sealing cover 13 form a cylindrical structure.

[0041] Please refer to Figures 1-2 , Figure 4 and Figures 6-7 . More preferably, in the embodiment of the present application, the atomizing device further comprises a power supply assembly, the power supply assembly comprises a bracket 70, an air flow switch 80 and an electric core 110, and the bracket 70 is sleeved with the end of the adapter seat 60 away from the liquid storage assembly 10. The bracket 70 is provided with a first air pipe 721 and a second air pipe 722 on the end face thereof facing the adapter seat 60. The first air pipe 721 is located at the side of the air flow passage 60a close to the first air passage 60b, and the second air pipe 722 is located at the side of the air flow passage 60a close to the second air passage 60c. The length of the first air pipe 721 protruding from the end face of the bracket 70 is less than the length of the second air pipe 722 protruding from the end face of the bracket 70. The bracket 70 is provided with the electric core 110 and the air flow switch 80 communicated with the second air pipe 722 on the side thereof away from the adapter seat 60.

[0042] Specifically, the bracket 70 comprises a main body 71, a first support plate 72, a second support plate 73 and a sleeve 74 which are integrally connected. The two ends of the main body 71 are fixed with the first support plate 72 and the second support plate 73 respectively. The main body 71 is, for example, an arc-shaped plate, so that a mounting cavity, for example, a mounting cavity for assembling the battery cell 110, can be formed between the main body 71, the first support plate 72 and the second support plate 73. The sleeve 74 is fixed to an end face of the first support plate 72 away from the second support plate 73. After the sleeve 74 is sleeved with the adapter 60, a relatively closed chamber is formed between the first support plate 72 and the adapter 60, so as to avoid the mist flowing out of the adapter 60 from flowing everywhere when the mist flows reversely. The end face of the first support plate 72 facing the adapter 60 is provided with a first air pipe 721 and a second air pipe 722. The positions and lengths of the first air pipe 721 and the second air pipe 722 are distinguished, for example, as shown in Figure 1 so that the mist flowing out of the adapter 60 is relatively easier or more preferentially to flow to the shorter first air pipe 721, and the longer second air pipe 722 further increases the backflow path of the mist flowing out of the second air outlet 60c into the second air pipe 722, so that it is more difficult for the mist to flow to the air flow switch 80 at the assembly position, effectively reducing the amount of mist flowing to the assembly position and improving the corrosion of the mist on the air flow switch 80.

[0043] More preferably, the end face of the second air pipe 722 away from the bracket 70 (i.e., the end face of the first support plate 72) extends into the adapter 60 and is spaced apart from the partition plate 61. In this way, the second air pipe 722 located outside the second air outlet 60c is relatively higher, increasing the difficulty of the mist flowing into the second air pipe 722 during the reverse blowing test, and better improving the corrosion of the mist on the air flow switch 80.

[0044] Please refer to Figure 7 More preferably, the power supply assembly further comprises a second liquid absorbing member 90, and the bracket 70 further comprises a third air pipe 723 arranged on the end face of the first support plate 72 away from the adapter 60, i.e., the third air pipe 723 is arranged on the end face of the first support plate 72 away from the adapter 60. The third air pipe 723 is in communication with the first air pipe 721, and one end of the third air pipe 723 away from the adapter 60 is used to contact the second liquid absorbing member 90. The third air pipe 723 can guide and concentrate the mist flowing out of the first air pipe 721, so that the mist can flow directionally, thereby facilitating the second liquid absorbing member 90 to absorb the mist flowing out of the third air pipe 723. The second liquid absorbing member 90 is, for example, liquid absorbing cotton. Through the cooperation of the third air pipe 723 and the second liquid absorbing member 90, the contact amount of the mist with the air flow switch 80 can be further reduced, and the corrosion of the mist on the air flow switch 80 can be better improved.

[0045] Preferably, the first air pipe 721 extends into the adapter 60 from the end face of the support 70 (i.e. the end face of the first support plate 72), and is spaced apart from the partition plate 61. In this way, the first air pipe 721 located outside the first air passage 60b is relatively higher, and the difficulty of the mist flowing into the first air pipe 721 during the back blowing test is appropriately increased, so as to avoid too much mist or condensate flowing into the first air pipe 721, and further avoid too much mist or condensate flowing into the second liquid suction member 90.

[0046] Please refer to Figure 7 Preferably, the side wall of the third air pipe 723 is provided with an air inlet 7231. The air inlet 7231 can be a strip-shaped gap formed on the side wall of the third air pipe 723, or the air inlet 7231 can also be a plurality of hole structures formed on the side wall of the third air pipe 723. Through the air inlet 7231, the external airflow can pass through the third air pipe 723, the first air pipe 721, the air passage 62, the connecting column 131, the atomizing pipe and the suction nozzle 40 in sequence with lower suction resistance when the user smokes the atomizing device.

[0047] The support 70 further comprises a mounting groove 724 arranged away from the end face of the adapter 60, and the airflow switch 80 is mounted in the mounting groove 724. The mounting groove 724 is arranged to mount or sleeve the airflow switch 80. Specifically, the mounting groove 724 can be annular or a clamping groove. Specifically, the mounting groove 724 is limited by an annular flange. For example, as shown in Figure 7 The mounting groove 724 is a flange, and the airflow switch 80 is sleeved in the flange. The flange provides a relatively small space for the airflow switch 80, so that the airflow switch 80 is more easily or more sensitive to detect the change of air pressure.

[0048] Please refer to Figure 1 The axial length of the mounting groove 724 is smaller than the axial length of the third air pipe 723. In this way, the mounted airflow switch 80 is relatively closer to the suction nozzle 40 than the second liquid suction member 90, so as to facilitate the axial spacing distribution of the second liquid suction member 90 and the airflow switch 80, and avoid the contact between the mist condensed on the second liquid suction member 90 and the airflow switch 80.

[0049] Please refer to Figure 7The end face of the support 70 away from the adapter seat 60 is provided with a limiting portion 725, the limiting portion 725 is used to abut against the circuit board 100, and the axial length of the limiting portion 725 is less than the axial length of the third air pipe 723. In this way, by using the designed atomization device, when the air flow switch 80, the second liquid absorbing member 90 and the circuit board 100 are assembled and used later, the air flow switch 80 and the circuit board 100 are relatively closer to the suction nozzle 40 than the second liquid absorbing member 90, so that the second liquid absorbing member 90 is prevented from corroding the air flow switch 80 and the circuit board 100 by mist. In addition, the air flow switch 80, the circuit board 100 and the second liquid absorbing member 90 are sequentially distributed in the axial direction, the space in the atomization device can be reasonably utilized, and the structure of the atomization device is compact.

[0050] Please refer to Figures 1-2 The atomization device further comprises a circuit board 100, and the atomization module 20 and the air flow switch 80 are electrically connected with the circuit board 100. The air flow switch 80 is, for example, a microphone or an air flow detection sensor, and the second liquid absorbing member 90 is, for example, EVA foam.

[0051] The atomization device further comprises an electric core 110, the electric core 110 is fixed in the mounting cavity formed between the main body frame 71, the first support plate 72 and the second support plate 73 of the support 70, and the second liquid absorbing member 90 is fixed between the third air pipe 723 and the electric core 110.

[0052] As shown in Figure 1 When the back-blowing test or the mist flows in the reverse direction, the mist generated at the atomization core flows into the air flow channel 60a through the butt joint column 131 and the air hole 62 in sequence. Since the size of the first air passage 60b is greater than the size of the second air passage 60c, the narrow second air passage 60c increases the difficulty of the mist passing through. The air flow channel 60a is provided with a relatively low first air pipe 721 and a relatively high second air pipe 722 at both ends, and the second air pipe 722 also prolongs the backflow path of the mist, thereby also increasing the difficulty of the mist passing through. Finally, the mist in the air flow channel 60a flows into the relatively low first air pipe 721, and is collected by the second liquid absorbing member 90 through the third air pipe 723.
