Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and more specifically to an atomizer and an atomization device. Background Art

[0002] Liquid storage tanks are widely used in electronic atomization devices. In electronic atomization devices, as the aerosol-generating matrix is ​​atomized, the air pressure in the liquid storage tank changes, resulting in different air pressures inside and outside the liquid storage tank, which causes the liquid storage tank to supply liquid to the atomization component unsmoothly, and the atomization component is prone to core burning. An existing solution is to use the design tolerance of the shell and the mounting bracket in the atomization component to form a gap, through which the liquid storage tank is exhausted or inhaled, so as to achieve a balance of air pressure inside and outside the liquid storage tank, so as to stably supply liquid to the atomization component. Then, due to the design tolerance between the two, there is a possibility of misalignment during assembly, so that the gap formed is uneven, resulting in the liquid storage tank being unable to evenly supply liquid to the atomization component, and the liquid entering the circumference of the atomization component is uneven. In the area with more liquid supply, the liquid may be directly sucked by the user because it is too late to atomize. In the area with less liquid supply, dry burning and burning will occur, affecting the user's experience. Utility Model Content

DETAILED DESCRIPTION

[0026] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0027] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0028] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0029] In a traditional atomizer, the atomizer shell and the mounting bracket utilize design tolerances so that an exhaust gap can be formed on one side close to the airflow channel. The exhaust gap is used to adjust the air pressure balance in the storage bin to ensure that the aerosol-forming matrix in the storage bin can flow smoothly and evenly to the atomizer core in the atomization space, and be heated by the atomizer core to form an aerosol for the user to inhale. However, due to the existence of this design, when assembling the atomizer assembly, there is a possibility of misalignment between the mounting bracket and the atomizer shell, which makes the exhaust gap around the outside of the mounting bracket uneven, making the storage bin uneven in supplying liquid to the atomizer core. In areas with more liquid supply, the atomizer core cannot be heated in time, and part of the aerosol-forming matrix is ​​flowed to the user along the airflow channel without being atomized. In areas with less liquid supply, the atomizer core is dry-burned and produces a burnt smell, which seriously affects the user's experience. In order to solve this problem. The present application proposes the following solution.

[0030] refer to Figure 1-10 The present application provides an atomizer, comprising an outer shell 100, a storage bin 200, an air flow channel 300 and an atomizer assembly 400, wherein the storage bin 200 is disposed in the outer shell 100 and is used to accommodate an aerosol-forming substrate, the air flow channel 300 is disposed in the storage bin 200, the atomizer assembly 400 is disposed in the storage bin 200 and is disposed at a position corresponding to the air flow channel 300, the atomizer assembly 400 comprises an atomizer housing 410, a mounting bracket 420 and a positioning member 430, the mounting bracket 420 is provided Placed in the atomizing shell 410, the mounting bracket 420 has an atomizing space 421, the positioning member 430 is arranged between the atomizing shell 410 and the mounting bracket 420, and the positioning member 430 is configured to position and install the mounting bracket 420 in the atomizing shell 410, and the positioning member 430 is provided with an exhaust channel 431, and the exhaust channel 431 is connected with the storage bin 200, the air flow channel 300 and the atomizing space 421, and the exhaust channel 431 is evenly arranged around the axis of the mounting bracket 420.

[0031] By setting a positioning piece 430 between the atomizing shell 410 and the mounting bracket 420, the positioning piece 430 can realize the positioning and installation of the mounting bracket 420 in the atomizing shell 410. Since the positioning piece 430 is provided with an exhaust channel 431, the exhaust channel 431 is evenly arranged around the axis of the mounting bracket 420, so that the exhaust around the mounting bracket 420 is uniform, which is convenient for the storage bin 200 to uniformly provide an aerosol-forming matrix into the atomizing space 421, thereby avoiding dry burning or insufficient heating, and improving the user experience.

[0032] It should be further explained that the exhaust mentioned in this article can include not only the storage bin 200 exhausting air to the outside through the exhaust channel 431, but also the outside taking air into the storage bin 200 through the exhaust channel 431, thereby achieving the air pressure balance inside and outside the storage bin 200, so as to ensure the stable supply of the aerosol forming matrix in the storage bin 200.

[0033] In one embodiment, the positioning member 430 includes a plurality of positioning portions 432, and the plurality of positioning portions 432 are disposed between the atomization shell 410 and the mounting bracket 420. The plurality of positioning portions 432 are evenly arranged around the axis of the mounting bracket 420, and an installation gap is provided between two adjacent positioning portions 432 to form the exhaust channel 431.

[0034] refer to Figure 8 The positioning portion 432 includes a protruding structure 4321, which is evenly and spaced apart around the axis of the mounting bracket 420 to form a positioning member 430, which can not only realize the positioning installation between the mounting bracket 420 and the atomization shell 410, but also form an installation gap due to the interval between the protruding structures 4321, and the installation gap forms an exhaust channel 431 for exhaust.

[0035] In one embodiment, the positioning portion 432 includes at least two protruding structures 4321, and the two protruding structures 4321 are arranged along the axial direction of the mounting bracket 420 and can be evenly arranged. Since there are multiple positioning portions 432 and they are evenly arranged around the axis of the mounting bracket 420, on the circumference of the mounting bracket 420, at least two protruding structures 4321 do not affect the formation of the exhaust channel 431, nor do they affect the uniformity of the exhaust channel 431. At the same time, it can also further improve the installation stability between the mounting bracket 420 and the atomization shell 410, and avoid unstable installation and the resulting shaking affecting the exhaust channel 431.

[0036] refer to Fig.10 The positioning member 430 is provided with a plurality of air flow holes 433 along the axial direction of the mounting bracket 420 . The plurality of air flow holes 433 are evenly arranged around the axis of the air flow channel 300 to form the exhaust channel 431 .

[0037] In one embodiment, the positioning member 430 is disposed on the side wall of the atomizing housing 410 close to the mounting bracket 420, or is disposed on the side wall of the mounting bracket 420 close to the atomizing housing 410. When the positioning member 430 is composed of a plurality of positioning portions 432 (convex structures 4321), the positioning portions 432 are arranged at intervals, and the gaps between them form an exhaust channel 431. When the positioning member 430 is provided with an air flow hole 433, the air flow hole 433 forms an exhaust channel 431, which does not affect the gas discharge, and can also achieve stable installation of the mounting bracket 420 and the atomizing housing 410.

[0038] In other embodiments, the positioning member 430 is arranged on the side wall of the atomizing shell 410 close to the mounting bracket 420 and on the side wall of the mounting bracket 420 close to the atomizing shell 410. The positioning members 430 on the mounting bracket 420 and the atomizing shell 410 can abut in the direction perpendicular to the axis of the mounting bracket 420, or can overlap with each other along the direction of the mounting bracket 420.

[0039] Furthermore, the positioning member 430 may be elastic. For example, according to usage habits, the end of the atomizer shell 410 close to the air flow channel 300 is defined as the upper end, and the end away from the air flow channel 300 is defined as the lower end. When the mounting bracket 420 is installed from its lower end, the positioning member 430 on the mounting bracket 420 is arranged closer to the lower end, which may cause a hidden danger of unstable installation. The positioning member 430 is elastic and may rely on elastic deformation to bring the positioning member 430 on the mounting bracket 420 closer to the upper end. The positioning member 430 on the mounting bracket 420 and the positioning member 430 on the atomizer shell 410 may limit each other, thereby limiting the movement of the atomizer shell 410 toward the upper end and the movement of the mounting bracket 420 toward the lower end, thereby making the installation more stable.

[0040] In one embodiment, a suction piece 500 is provided on a side of the airflow channel 300 away from the atomization assembly 400, and a liquid inlet hole 411 is provided on the side wall of the atomization shell 410. The liquid inlet hole 411 is configured to supply an aerosol-forming matrix to the atomization space 421. An atomization core 450 is provided in the atomization space 421. The atomization core 450 can heat the aerosol-forming matrix to form an aerosol, so that when a user uses it, the aerosol can flow along the airflow channel 300 to the suction piece 500 for the user to inhale. The liquid inlet hole 411 can also guide air, so as to adjust the air pressure inside and outside the storage bin 200. The liquid inlet hole 411 is connected with the airflow channel 300 and the atomization space 421 through the exhaust channel 431. When the air pressure inside the storage bin 200 is lower than the external air pressure, the storage bin 200 is in a negative pressure or vacuum, and the aerosol-forming matrix cannot be guided to the atomization core 450. At this time, the liquid inlet hole 411 is used to guide air into the storage bin 200. The outside air can enter the storage bin 200 through the atomization space 421, the airflow channel 300, the exhaust channel 431 and the liquid inlet hole 411 in turn, thereby increasing the air inside the storage bin 200, balancing the air pressure, and the storage bin 200 stably provides the aerosol-forming matrix to the atomization core 450. When the air pressure in the storage bin 200 is greater than the external air pressure, on the one hand, the aerosol matrix is ​​supplied too quickly, and the aerosol-forming matrix is ​​used by the user through the suction piece 500 before it is heated and atomized. On the other hand, it may also cause an aerosol matrix leakage accident in the entire atomizer. At this time, the liquid inlet hole 411 is used to guide the air in the storage bin 200 to pass through the exhaust channel 431 and the airflow channel 300 in sequence and discharge from the outer shell 100, thereby reducing the air pressure in the storage bin 200 to ensure a stable supply of the aerosol-forming matrix.

[0041] In order to avoid leakage accidents of the aerosol forming matrix, along the axial direction of the mounting bracket 420, the distance from the liquid inlet hole 411 to the air flow channel 300 is greater than the distance from the exhaust channel 431 to the air flow channel 300, so that the gas is discharged from the upper end without affecting the guidance of the aerosol forming matrix.

[0042] In one embodiment, along the axial direction of the mounting bracket 420, the mounting bracket 420 has a first end 422 and a second end 423, the positioning member 430 is provided between the first end 422 and the atomizing shell 410, and the first end 422 is respectively connected to the airflow channel 300 and the exhaust channel 431, and the second end 423 is tightly connected to the atomizing shell 410, which can also further prevent the aerosol-forming matrix from leaking from the second end 423 (lower end).

[0043] It should be further explained that the axis of the mounting bracket 420 mentioned herein is a line connecting the midpoints of the first end 422 and the second end 423 , and the direction of the axis is parallel to the direction of the line connecting the midpoints of the first end 422 to the second end 423 .

[0044] refer to Figure 2 The atomizer also includes a mounting base 600, the outer shell 100 is arranged on the mounting base 600, the atomizer assembly 400 and the storage bin 200 are arranged on the mounting base 600; the mounting base 600 is provided with a mounting groove 610, and the atomizer assembly 400 is arranged in the mounting groove 610; it also includes a power supply base 700, and the power supply base 700 is arranged on a side of the mounting base 600 away from the outer shell 100. A liquid storage part 440 is provided in the atomization space 421, and an atomizer core 450 is arranged in the liquid storage part 440. The liquid storage part 440 can store and guide the aerosol-forming matrix flowing out of the storage bin 200 to the atomizer core 450. The atomizer core 450 is used to heat the aerosol matrix to generate an aerosol, and the atomizer core 450 is electrically connected to the power supply base 700.

[0045] In one embodiment, an injection plug 800 is further provided on the outer shell 100, and the injection plug 800 is connected to the storage bin 200, and is used to replenish the aerosol-forming matrix into the storage bin 200. At this time, the exhaust channel 431 can discharge the gas in the storage bin 200 out of the outer shell 100 through the airflow channel 300, so as to avoid leakage or injection inconvenience due to air pressure during the injection of the aerosol-forming matrix. When the user uses it, heat is also generated during the heating process of the atomizer core 450. When the heat is conducted to the storage bin 200, the aerosol-forming matrix inside it will expand due to the heat, so that part of the gas is discharged from the storage bin 200. The exhaust channel 431 can also discharge this part of the gas from the airflow channel 300 out of the outer shell 100, so as to avoid the thermal expansion of the aerosol-forming matrix affecting the air pressure balance in the storage bin 200, thereby ensuring that the storage bin 200 stably supplies the aerosol-forming matrix to the atomizer core 450.

[0046] The present application also provides an atomization device including the above-mentioned atomizer, and also including a power supply component. A power supply electrode 710 is provided on the power supply base 700. The power supply component is electrically connected to the power supply electrode 710 and can provide power for the atomization core 450 to work.

[0047] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
