In addition, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0030] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] Please refer to Figures 1 to 3, this application provides an electronic atomization device 100, which includes a main body 10, a housing 20 and a display screen 30. An air flow channel 11 is formed inside the main body 10; the housing 20 is sleeved on the outer periphery of the main body 10, and an accommodation space 21 independent of the air flow channel 11 is formed between the inner surface of the housing 20 and the outer surface of the main body 10. The display screen 30 is arranged in the accommodation space 21, and at least a part of the housing 20 corresponding to the display screen 30 is arranged as a transparent structure. On the one hand, by using the inner surface of the housing 20 and the outer surface of the main body 10 to form the accommodation space 21 (see Figure 2 , Figure 2 , the display screen 30 is hidden, and the accommodation space 21 can be observed), so that a sandwich space structure continuously arranged along the outer periphery of the main body 10 can be formed between the two. The continuous display screen 30 can be arranged by using this continuous accommodation space 21, so that a display effect can be formed on the entire surface of the housing 20 of the electronic atomization device 100, ensuring the consistency of the appearance of the housing 20. Compared with the way of displaying by opening a window on the housing 20, the solution of this embodiment can achieve a continuous display effect, broaden the design space of the appearance design of the housing 20 of the electronic atomization device 100, and help to improve the appearance effect of the product. On the other hand, by independently arranging the air flow channel 11 and the accommodation space 21, the two are not connected to each other. In this way, when the user exhales smoke in the air flow channel 11, the generated water vapor or condensate will not enter the accommodation space 21, thus preventing the display screen 30 from being eroded by water vapor or covered by an oil film formed after being attached by water vapor, and ensuring the display integrity and use reliability of the display screen 30.

[0032] Optionally, in the above example, the display screen 30 can be continuously arranged in the accommodation space 21, or arranged in a whole circle around the outer periphery of the main body 10. Of course, in other examples, the display screen 30 can also be arranged only in one or several parts of the accommodation space 21, that is, the display screen 30 is not continuously arranged along the outer periphery of the main body 10. Correspondingly, the housing 20 can be entirely arranged as a transparent structure, or only the position where the display screen 30 is arranged is correspondingly arranged as a transparent structure. This is not limited here.

[0033] Exemplarily, the display screen 30 can be a flexible display screen, so that the flexible display screen can be bent according to the outer contour of the main body 10 to fit the main body 10. Or, the display screen 30 can also be a non-flexible display screen. For example, the shape of the display screen 30 is preset according to the shape of the accommodation space 21 to facilitate loading the display screen 30 into the accommodation space 21.

[0034] In some embodiments, one end of the housing 20 is provided with a mouthpiece 22 communicating with the air flow channel 11, and the other end is formed as a first opening (not shown). The accommodating space 21 communicates with the first opening. The electronic atomization device 100 further includes a base assembly 40. The base assembly 40 covers the first opening to seal the display screen 30 in the accommodating space 21. By forming the first opening, the main body 10 can be loaded into the housing 20 through the first opening, and the display screen 30 can be loaded into the accommodating space 21. By using the base assembly 40 to cover the first opening, the main body 10 can be fixed in the housing 20, and the accommodating space 21 can be sealed to prevent the gas and liquid in the air flow channel 11 from entering the accommodating space 21.

[0035] The main body 10 of the electronic atomization device 100 usually further includes an air flow sensor 14 (microphone). The air flow sensor 14 is used to sense the air pressure change in the air flow channel 11 to control the start and stop of the electronic atomization device 100. However, in the air flow channel 11, the starting hole 4111 of the air flow sensor 14 is easily blocked by condensate, thus affecting the sensitivity of the air flow sensor 14. Therefore, in some embodiments, the electronic atomization device 100 further includes a base assembly 40. The main body 10 includes an oil cup 12 and an atomization assembly 13. The outer surface of the oil cup 12 and the inner surface of the housing 20 form an accommodating space 21. The oil cup 12 is internally formed with an independent liquid storage cavity 121 and an accommodating cavity 122. The ends of the liquid storage cavity 121 and the accommodating cavity 122 away from the mouthpiece 22 are respectively formed with a second opening (not shown) and a third opening (not shown). The base assembly 40 is connected to the oil cup 12 to cover the second opening and the third opening. The air flow channel 11 includes an atomization channel 111 and a sensing air duct 112. The atomization channel 111 is formed in the liquid storage cavity 121, and the atomization assembly 13 is arranged in the atomization channel 111. The sensing air duct 112 is formed in the accommodating cavity 122. The atomization channel 111 and the sensing air duct 112 both communicate with the mouthpiece 22. It can be understood that the liquid storage cavity 121 is used to store the atomization medium. The atomization medium can be atomized into aerosol through the absorption and heating of the atomization assembly 13. The aerosol is transmitted to the mouthpiece 22 through the atomization channel 111 for the user to inhale. The sensing air duct 112 communicates with the mouthpiece 22. When the user inhales using the mouthpiece 22, the air flow sensor 14 can sense the air pressure change through the sensing air duct 112. By independently arranging the liquid storage cavity 121 and the accommodating cavity 122 and using the base assembly 40 to cover the second opening and the third opening, in this way, the atomization channel 111 located in the liquid storage cavity 121 and the sensing air duct 112 located in the accommodating cavity 122 can be independent of each other in the structure of the oil cup 12. During use, the atomization channel 111 and the sensing air duct 112 do not interfere with each other, thus preventing the condensate generated in the atomization channel 111 from entering the sensing air duct 112 and affecting the sensitivity of the air flow sensor 14.

[0036] Optionally, the accommodating cavity 122 can also be used to place a battery. When the battery is placed in the accommodating cavity 122, the gap formed between the outer periphery of the battery and the inner wall of the accommodating cavity 122 constitutes the induction air duct 112. When the user sucks through the suction nozzle 22, the change in negative pressure can be detected by the airflow sensor 14 through the induction air duct 112.

[0037] In some embodiments, referring to Figure 3 and Figure 5 , one end of the liquid storage cavity 121 facing the suction nozzle 22 is provided with a ventilation hole 1212. The ventilation hole 1212 communicates with the liquid storage cavity 121. A first oil-absorbing cotton 221 is arranged in the suction nozzle 22, and the first oil-absorbing cotton 221 covers at least a part of the ventilation hole 1212. By providing the ventilation hole 1212, the liquid storage cavity 121 can perform air return and exhaust through the ventilation hole 1212 to balance the air pressure inside and outside the liquid storage cavity 121. Specifically, when the user uses the electronic atomization device 100, through the suction effect, the atomization medium in the liquid storage cavity 121 is continuously consumed and reduced. In order to ensure that the atomization medium can be continuously and smoothly absorbed from the liquid storage cavity 121 to the atomization core, at this time, it is necessary for the liquid storage cavity 121 to be able to communicate with the external air pressure. At this time, the ventilation hole 1212 can be used to communicate the liquid storage cavity 121 and the external air pressure to realize the air return of the liquid storage cavity 121 and ensure the balance of the air pressure inside and outside the liquid storage cavity 121. During the process of injecting the atomization medium into the liquid storage cavity 121, the ventilation hole 1212 can be used to timely discharge the air in the liquid storage cavity 121, thereby balancing the air pressure inside and outside the liquid storage cavity 121 and avoiding the problem of squeezing oil where the atomization medium sprays out from the oil injection port due to untimely exhaust. In addition, when used in a high-temperature environment, since the liquid expands thermally in a high-temperature environment, the internal pressure of the liquid storage cavity 121 may increase, and the air can also be exhausted through the ventilation hole 1212, thereby reducing the problem of liquid leakage caused by excessive internal pressure. On this basis, in order to prevent the atomization medium from flowing out of the ventilation hole 1212 during the transportation or use of the electronic atomization device 100, the first oil-absorbing cotton 221 is provided to cover a part of the ventilation hole 1212. In this way, it can ensure that the air return or exhaust function of the ventilation hole 1212 is not affected (for example, when the negative pressure in the liquid storage cavity 121 is relatively large, air can enter the liquid storage cavity 121 through the pores of the first oil-absorbing cotton 221 to balance the internal and external air pressures), and it can also use the first oil-absorbing cotton 221 to adsorb and lock the atomization medium to prevent the atomization medium from overflowing to other areas and ensure the use reliability of the main unit 10. Optionally, the first oil-absorbing cotton 221 can only cover a part of the area of the ventilation hole 1212 (as shown in Figure 5 ), or can completely cover the entire ventilation hole 1212, and no limitation is made here.

[0038] In some alternative embodiments, the ventilation hole 1212 can be a capillary hole.

[0039] Optionally, in order to prevent the atomization medium from leaking or overflowing from the liquid storage chamber 121, a second oil-absorbing cotton can also be provided in the liquid storage chamber 121, and the second oil-absorbing cotton can be flexibly arranged according to the shape and capacity of the liquid storage chamber 121. By using the second oil-absorbing cotton, the atomization medium in the liquid storage chamber 121 can be locked, further reducing the risk of liquid leakage from the oil cup 12.

[0040] In some embodiments, an oil injection hole 1213 is further provided at one end of the liquid storage chamber 121 facing the nozzle 22. The oil injection hole 1213 and the ventilation hole 1212 are arranged at intervals. The nozzle 22 is further provided with a seal 222, and the seal 222 covers the oil injection hole 1213. By using the oil injection hole 1213, the oil cup 12 can inject the atomization medium into the liquid storage chamber 121 before installing the seal 222. In order to prevent oil leakage during the use of the electronic atomization device 100, the seal 222 can be used to seal the oil injection hole 1213 to ensure that the atomization medium does not flow out of the oil injection hole 1213. Exemplarily, as Figure 5 shown, two ventilation holes 1212 and two oil injection holes 1213 can be provided on the surface of one end of the oil cup 12 facing the nozzle 22, and the ventilation holes 1212 and the oil injection holes 1213 are alternately arranged at intervals along the circumference of the outlet of the atomization channel 111 of the oil cup 12. Optionally, the seal 222 can be a flexible member, such as a silicone member, etc. By using its flexible characteristics, the fitting effect between the seal 222 and the oil cup 12 can be improved, so as to achieve a better sealing effect.

[0041] In some specific embodiments, the aperture of the oil injection hole 1213 is greater than or equal to the aperture of the ventilation hole 1212.

[0042] In some embodiments, an air outlet 1222 is provided at one end of the accommodation cavity 122 facing the nozzle 22, and a conduction groove 2221 communicating with the air outlet 1222 is provided on the outer surface of the seal 222. The air outlet 1222 is communicated with the nozzle 22 through the conduction groove 2221. By using the air outlet 1222, the induction channel located in the accommodation cavity 122 can be communicated to the nozzle 22. When the user sucks using the nozzle 22, the airflow sensor 14 can sense the negative pressure change through the induction channel, thereby controlling the start and stop of the electronic atomization device 100. Since openings (air outlet 1222, ventilation hole 1212) are provided at one end of both the accommodation cavity 122 and the liquid storage cavity 121 facing the nozzle 22, in order to ensure the mutual independence of the atomization channel 111 and the induction air channel 112, by providing the seal 222, the seal 222 can be used to separate the air outlet 1222 and the ventilation hole 1212, further ensuring that the atomization channel 111 and the induction air channel 112 cannot communicate with each other at one end facing the nozzle 22, so as to prevent the condensate generated in the atomization channel 111 from flowing into the induction air channel 112. By providing the conduction groove 2221 on the outer surface of the seal 222, the conduction groove 2221 can communicate the nozzle 22 with the air outlet 1222, thereby ensuring that the induction air channel 112 can be communicated to the nozzle 22. Optionally, the nozzle 22 includes a main channel 223 and a bypass port 224 provided on the inner wall of the main channel 223. The main channel 223 is communicated with the atomization channel 111, and the bypass port 224 is communicated with the air conduction groove, so as to realize the simultaneous communication of the nozzle 22 with both the atomization channel 111 and the induction air channel 112.

[0043] In some embodiments, an installation groove 123 is further provided at one end of the oil cup 12 facing the nozzle 22. The installation groove 123 is recessed towards the liquid storage cavity 121. The ventilation hole 1212, the oil injection hole 1213 and the air outlet 1222 are all provided at the bottom of the installation groove 123. At least a part of the first oil absorption cotton 221 and the seal 222 are accommodated in the installation groove 123. By using the installation groove 123 to accommodate a part of the first oil absorption cotton 221 and the seal 222, on the one hand, it can improve the installation stability and accuracy of the first oil absorption cotton 221 and the seal 222, and prevent relative shaking between the first oil absorption cotton 221 and the seal 222 and the oil cup 12. On the other hand, it can also reduce the size of the main body 10 in the axial direction of the atomization channel 111, making the structure of the main body 10 more compact. Optionally, when the main body 10 is assembled with the outer shell 20, the seal 222 can abut between the inner wall of the outer shell 20 and the inner wall of the main body 10 to ensure stable installation of the structure.

[0044] In some embodiments, please refer to Figure 4The outer periphery of the oil cup 12 is also provided with a limiting flange 124, which abuts against the inner surface of the housing 20 to seal the accommodating space 21. When the display screen 30 is installed in the accommodating space 21, the top edge of the display screen 30 can abut against the limiting flange 124, so that the installation height of the display screen 30 can be controlled by the position of the limiting flange 124 to prevent the display screen 30 from sliding into one end of the suction nozzle 22. In addition, the limiting flange 124 can also be used to seal the accommodating space 21 to prevent the airflow generated by the suction nozzle 22 from entering the accommodating space 21.

[0045] In some embodiments, the base assembly 40 includes a base bracket 41 and a control circuit board 42 which are arranged in sequence. The base bracket 41 is used to seal the second opening and the third opening. The airflow sensor 14 is arranged on the surface of the control circuit board 42 facing the base bracket 41. The base bracket 41 is provided with an installation cavity corresponding to the airflow sensor 14. The installation cavity is provided with a start hole 4111 which is connected to the sensing airway 112. When the control circuit board 42 is installed to the base bracket 41, the airflow sensor 14 is accommodated in the installation cavity. By providing the base bracket 41 and the installation cavity formed by the base bracket 41, the control circuit board 42 can be separated from the accommodating cavity 122 to avoid mutual interference between the accommodating cavity 122 and the circuit board. It can also be connected to the accommodating cavity 122 through the start hole 4111 to ensure that the airflow sensor 14 can be connected to the sensing airway 112.

[0046] Optionally, the airflow sensor 14 can be mounted on the control circuit board 42 in the form of a patch, which can avoid pulling of the production assembly connection wires, reduce the assembly process steps, and improve assembly efficiency.

[0047] Optionally, the base assembly 40 also includes a bottom cover 43, which is arranged on the side of the control circuit board 42 away from the base bracket 41, and the bottom cover 43 is slightly larger than the base bracket 41. When the base assembly 40 is connected to the oil cup 12, the base bracket 41 covers the second opening and the third opening to form a seal at the end of the oil cup 12 away from the suction nozzle 22. At the same time, the bottom cover 43 covers the first opening of the outer shell 20 to form a closed structure at the bottom of the outer shell 20.

[0048] In some embodiments, please refer to Figure 3 The base assembly 40 includes a control circuit board 42 and a flexible circuit board 44, and the display screen 30 is connected to the control circuit board 42 via the flexible circuit board 44. The flexible circuit board 44 has good bending properties, and can improve the adaptability and connection stability of the display screen 30 during installation.

[0049] Optionally, the display screen 30 can be adhered to the outer peripheral side of the oil cup 12 by setting adhesive tape, thereby further improving the installation stability of the display screen 30 in the accommodation space 21. The flexible circuit board 44 can be integrally provided with the display screen 30, and before installation, the flexible circuit board 44 and the display screen 30 are substantially in a flattened state. Specifically, the display screen 30 can be assembled into the accommodation space 21 in the following manner:

[0050] In one example, after the base assembly 40 is assembled in sequence first, the flexible circuit board 44 is connected to the display interface on the control circuit board 42. Then, the main body 10 and the housing 20 are assembled. Finally, the display screen 30 is folded by 90°, so that the display screen 30 and the flexible circuit board 44 are in a mutually bent state, and then the display screen 30 is loaded into the accommodation space 21, and the display screen 30 is adhered to the outer wall of the oil cup 12 by using adhesive tape.

[0051] In another example, first, the display screen 30 is attached to the outer peripheral side of the main body 10, and the flexible circuit board 44 is bent. Then, the flexible circuit board 44 is connected to the display interface of the control circuit board 42. Finally, the base assembly 40 is assembled with the main body 10 and the housing 20.

[0053] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments.
