[0031] An atomizer and an electronic atomization device in this application are described below with reference to the accompanying drawings. For ease of description, the accompanying drawings only show structures related to this application.

[0032] Referring to FIG. 1 to FIG. 4, an electronic atomization device 1 disclosed in at least one embodiment of this application includes a power supply assembly 200 and an atomizer 100. The power supply assembly 200 is electrically connected to the atomizer 100. The atomizer 100 is configured to atomize an atomizable medium under an action of electric energy provided by the power supply assembly 200 and form an aerosol for a user to inhale.

[0033] The atomizer 100 includes a housing 10. The power supply assembly 200 includes a battery core 210 arranged in the housing 10. The battery core 210 is configured to provide electrical energy for the atomizer 100 to atomize the atomizable medium. It should be understood that, generally, a main control board configured to control turning on or turning off of the atomizer 100 and a lamp board configured to remind the user are further arranged in the housing 10. The battery core 210 is extremely prone to shaking during use. When the battery core 210 shakes, there is a risk that a tab of the battery core 210 is in contact with the main control board and the lamp board, resulting in a short circuit.

[0034] To prevent the battery core 210 from shaking inside the housing 10 and prevent the tab of the battery core 210 from being in mis-contact with the main control board and the lamp board, the power supply assembly 200 further includes a support member 220 arranged in the housing 10. The support member 220 performs support between at least one pole of the battery core 210 and the housing 10. Specifically, the support member 220 performs support between two poles of the battery core 210 and the housing 10, to support the battery core 210, so as to prevent the battery core 210 from shaking in the housing 10. More specifically, the support member 220 includes foam, and the foam is adhered to the two poles of the battery core 210 through an adhesive paper.

[0035] Referring to FIG. 5 and FIG. 6, the housing 10 of the atomizer 100 is provided with a first air inlet hole 11, and external air may enter the housing 10 through the first air inlet hole 11. To adjust inhalation resistance to satisfy a user requirement, the atomizer 100 further includes an inhalation resistance adjustment member 20 arranged in the housing 10, and the inhalation resistance adjustment member 20 is slidably connected to the housing 10. The inhalation resistance adjustment member 20 is provided with a plurality of second air inlet holes 21 with the same air inlet areas. When the inhalation resistance adjustment member 20 is operable to slide relative to the housing 10, at least part of the second air inlet holes 21 are controlled to communicate with the first air inlet hole 11.

[0036] During actual use, if the user needs large inhalation resistance, an area in which the second air inlet holes 21 communicate with the first air inlet hole 11 is reduced as much as possible. Alternatively, if the user needs small inhalation resistance, an area in which the second air inlet holes 21 communicate with the first air inlet hole 11 is increased as much as possible. In this way, requirements of the user for different inhalation resistance can be satisfied, so that inhalation experience of the user is improved.

[0037] Referring to FIG. 7, in some embodiments, a surface of the housing 10 facing the inhalation resistance adjustment member 20 is provided with a sliding groove 12, the inhalation resistance adjustment member 20 is slidably mated with the sliding groove 12, and the first air inlet hole 11 is provided on a bottom wall of the sliding groove 12 in a run-through manner. Specifically, the size of the sliding groove 12 along a sliding path of the inhalation resistance adjustment member 20 is larger than the size of the inhalation resistance adjustment member 20, so that the inhalation resistance adjustment member 20 is slidable.

[0038] Further, the sliding groove 12 is configured to limit sliding of the inhalation resistance adjustment member 20 between a first position and a second position, and as the inhalation resistance adjustment member 20 slides from the first position to the second position, the area in which the second air inlet holes 21 communicate with the first air inlet hole 11 gradually increases. Specifically, groove walls of the sliding groove 12 located at two opposite ends of the inhalation resistance adjustment member 20 along a sliding direction of the inhalation resistance adjustment member 20 can limit the inhalation resistance adjustment member 20 to the first position and the second position, respectively. Specifically, when the inhalation resistance adjustment member 20 is located at the first position, the area in which the second air inlet holes 21 communicate with the first air inlet hole 11 is the smallest, so that the inhalation resistance is the largest, when the inhalation resistance adjustment member 20 is located at the second position, the area in which the second air inlet holes 21 communicate with the first air inlet hole 11 is the largest, so that the inhalation resistance is the smallest.

[0039] In some embodiments, a first convex rib 13 protrudes from the bottom wall of the sliding groove 12 facing the inhalation resistance adjustment member 20. The first convex rib 13 is enclosed on an outer periphery of the first air inlet hole 11, and abuts between the bottom wall of the sliding groove 12 and the inhalation resistance adjustment member 20. Specifically, the first convex rib 13 and the bottom wall of the sliding groove 12 are integrally formed. During actual use, the first convex rib 13 may support the inhalation resistance adjustment member 20. In addition, compared with that the inhalation resistance adjustment member 20 directly slides on the bottom wall of the sliding groove 12, the arrangement of the first convex rib 13 can reduce a contact area between the inhalation resistance adjustment member 20 and the bottom wall of the sliding groove 12, so that the user slides smoother, and use comfort of the user is improved.

[0040] In some embodiments, the inhalation resistance adjustment member 20 includes a body 22 and an operating portion 23 protruding from the side of the body 22. The body 22 is mated with the bottom wall of the sliding groove 12. The operating portion 23 is accommodated in the first air inlet hole 11, and is exposed to an air inlet side of the first air inlet hole 11. On the sliding path of the inhalation resistance adjustment member 20, the size of the first air inlet hole 11 is greater than the size of the operating portion 23, and the operating portion 23 is operable to drive the body 22 to slide relative to the bottom wall of the sliding groove 12.

[0041] During actual use, the user may push the operating portion 23 with a finger, so that the operating portion 23 moves in the first air inlet hole 11, and drives the body 22 to slide relative to the housing 10. In this way, it is convenient to adjust the quantity or the area in which the second air inlet holes 21 communicate with the first air inlet hole 11, to improve use experience of the user.

[0042] To adjust the area in which the second air inlet holes 21 communicate with the first air inlet hole 11, in some embodiments, all of the second air inlet holes 21 are provided on the body 22, and on the sliding path of the inhalation resistance adjustment member 20, all of the second air inlet holes 21 are distributed on two sides of the operating portion 23 with uneven quantities. The operating portion 23 is operable to drive the body 22 to slide relative to the bottom wall of the sliding groove 12, and the second air inlet holes 21 located on one side of the operating portion 23 communicate with the first air inlet hole 11. Specifically, there are five second air inlet holes 21. Two of the second air inlet holes 21 are distributed on one side of the operating portion 23, and the remaining three of the second air inlet holes 21 are distributed on the other side of the operating portion 23. When the operating portion 23 drives the body 22 to slide, two second air inlet holes 21 located on one side of the operating portion 23 communicate with the first air inlet hole 11, and three second air inlet holes 21 on the other side of the operating portion 23 are blocked by the bottom wall of the sliding groove 12; or three second air inlet holes 21 located on one side of the operating portion 23 communicate with the first air inlet hole 11, and two second air inlet holes 21 on the other side of the operating portion 23 are blocked by the bottom wall of the sliding groove 12.

[0043] It may be understood that, the foregoing descriptions are merely examples for description, and should not be understood as a limitation to this application. For example, there may alternatively be seven second air inlet holes 21, including three second air inlet holes 21 and four second air inlet holes 21 provided on two sides of the operating portion 23 respectively, which can also achieve a purpose of changing the area in which the second air inlet holes 21 communicate with the first air inlet hole 11 and adjusting the inhalation resistance.

[0044] Referring to FIG. 8 and FIG. 9, in some embodiments, the atomizer 100 further includes a first sealing member 30, and the first sealing member 30 includes a sealing silicone. The atomizer 100 further includes an airflow induction member 50 sealed by the first sealing member 30. The first sealing member 30 is provided with an activation airway for the airflow induction member 50. Specifically, the first sealing member 30 is provided with a fixing groove 33. The airflow induction member 50 is engaged and sealed in the fixing groove 33. The activation airway 34 enables the fourth air inlet hole 41 to communicate with the airflow induction member 50. More specifically, the airflow induction member 50 may be a microphone that can sense a negative pressure, so as to determine whether to turn on the battery core 210 to supply power to a heating element. The first sealing member 30 can seal the airflow induction member 50, to construct the activation airway 34; and fix the inhalation resistance adjustment member on the housing, so that a quantity of component parts is reduced, assembly difficulty is reduced, and costs are saved.

[0045] The atomizer 100 further includes a fixing base 40. The fixing base 40 is mated with the housing 10, and is located on an air outlet side of the first air inlet hole 11. The first sealing member 30 is sealed between the housing 10 and the fixing base 40. The first sealing member 30 is provided with a third air inlet hole 31, and the fixing base 40 is provided with a fourth air inlet hole 41 communicating with the third air inlet hole 31. The body 22 of the inhalation resistance adjustment member 20 is slidably connected to the side of the first sealing member 30 away from the fixing base 40, and the first air inlet hole 11, the part of the second air inlet holes 21 communicating with the first air inlet hole 11, the third air inlet hole 31, and the fourth air inlet hole 41 sequentially communicate with each other, to form an air inlet channel.

[0046] Further, a second convex rib 32 protrudes from the surface of the first sealing member 30 facing the body 22 of the inhalation resistance adjustment member 20. The second convex rib 32 is enclosed on the edge of the end surface of the third air inlet hole 31, and abuts against the first sealing member 30 and the body 22. Specifically, the second convex rib 32 and the first sealing member 30 may be integrally injection molded. During actual use, the second convex rib 32 can seal a gap between the third air inlet hole 31 and the second air inlet holes 21 currently communicating with the first air inlet hole 11, so as to prevent a problem of poor inhalation resistance consistency caused by air leakage. In addition to a sealing function, the second convex rib 32 can support the body 22. Compared with a manner that the first sealing member 30 directly supports the body 22, a contact area between the body 22 and the first sealing member 30 can be reduced, so that sliding of the body 22 is smoother, thereby improving the user experience.

[0047] In some embodiments, the first sealing member 30 is sequentially provided with a first opening 311, an intermediate opening 313, and a second opening 312 along the sliding path of the inhalation resistance adjustment member 20. The intermediate opening 313 enables the first opening 311 to communicate with the second opening 312, and the first opening 311, the second opening 312, and the intermediate opening 313 are jointly constructed to form the third air inlet hole 31. The support portion 24 is slidably accommodated in the intermediate opening 313, and drives the second air inlet holes 21 located on one side of the operating portion 23 to communicate with the corresponding first opening 311 or the second opening 312.

[0048] Specifically, when the inhalation resistance adjustment member 20 is located at the first position, two second air inlet holes 21 on one side of the operating portion 23 of the inhalation resistance adjustment member 20 communicate with the first opening 311, air inlet ends of three second air inlet holes 21 on the other side of the operating portion 23 are blocked by the bottom wall of the sliding groove 12, and air outlet ends are blocked by the surface of the first sealing member 30. When the inhalation resistance adjustment member 20 is located at the second position, three second air inlet holes 21 on one side of the operating portion 23 of the inhalation resistance adjustment member 20 communicate with the second opening 312, air inlet ends of two second air inlet holes 21 on the other side of the operating portion 23 are blocked by the bottom wall of the sliding groove 12, and air outlet ends are blocked by the surface of the first sealing member 30.

[0049] In some embodiments, the housing 10 is provided with an air outlet hole 14. The atomizer 100 further includes a central tube 60 arranged in the housing 10. The central tube 60 enables the fourth air inlet hole 41 to communicate with the air outlet hole 14. During actual use, the user inhales through the air outlet hole 14, external air can enter from the first air inlet hole 11 under an action of an inhalation force, is sequentially transmitted through the air inlet channel and the central tube 60 to the air outlet hole 14, and enter the mouth of the user.

[0050] In some embodiments, the atomizer 100 further includes a liquid absorbing member 70. The liquid absorbing member 70 is provided with a fifth air inlet hole 71. The fifth air inlet hole 71 enables the central tube 60 to communicate with the fourth air inlet hole 41. Specifically, the liquid absorbing member 70 is mounted directly above the fourth air inlet hole 41 of the fixing base 40. When airflow exits from the fourth air inlet hole 41, the airflow enters the liquid absorbing member 70, and the liquid absorbing member 70 may perform velocity reduction and noise reduction processing on the airflow. The liquid absorbing member 70 includes liquid absorbing cotton. The liquid absorbing cotton is in a porous structure, and has a strong liquid absorbing capacity and a strong liquid storage capacity. Further, a flow guide groove is further formed on the surface of the fixing base 40, and condensate can be flow guided by the flow guide groove to the liquid absorbing member 70, and is absorbed, to prevent leakage.

[0051] Referring to FIG. 10, in some embodiments, the atomizer 100 further includes a second sealing member 80 mated with the fixing base 40, and the second sealing member 80 is provided with a sixth air inlet hole 81. An air inlet end of the central tube 60 fixedly communicates with an air outlet end of the sixth air inlet hole 81, and the fourth air inlet hole 41 communicates with an air inlet end of the sixth air inlet hole 81. Specifically, the second sealing member 80 includes a sealing silicone, to prevent leakage of the atomizable medium and affect the inhalation experience.

[0052] Further, a third convex rib 82 protrudes from the surface of the second sealing member 80 facing the fixing base 40. The third convex rib 82 is enclosed on an outer periphery of the sixth air inlet hole 81, and abuts between the fixing base 40 and the second sealing member 80. Specifically, the third convex rib 82 and the second sealing member 80 are integrally injection molded. During actual use, the third convex rib 82 can seal a gap between the fixing base 40 and the second sealing member 80, to prevent external air from entering. More specifically, the second sealing member 80 is further provided with a cable hole 83, and the cable hole 83 is spaced apart from the sixth air inlet hole 81. The third convex rib 82 includes a sealing horizontal rib 821 and a sealing vertical rib 822. The sealing horizontal rib 821 is configured to prevent external air from entering the sixth air inlet hole 81. The sealing vertical rib 822 is configured to isolate the sixth air inlet hole 81 from the cable hole 83, to prevent air in the cable hole 83 from entering the sixth air inlet hole 81. In this way, insensitive activation and unstable inhalation resistance caused by air leakage can be avoided.
