Description

Technical Field

[0001] The utility model relates to the technical field of atomization, and particularly relates to an atomization component, an atomizer and an electronic atomization device. Background Art

[0002] In an atomization device, an atomization component can suck an atomization matrix in a sealed liquid storage cavity and heat it to form an aerosol. As the atomization matrix is consumed, a negative pressure will be formed in the liquid storage cavity. If the pressure in the liquid storage cavity cannot be balanced in time, it may cause the atomization matrix to not be smoothly conducted to the atomization component. To solve this problem, some atomization devices introduce a ventilation component.

[0032] The present utility model will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. 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, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. 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 descriptions in the specification and the general technical knowledge in the art.

[0033] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0034] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connections (couplings).

[0035] In one embodiment, an atomization assembly is provided. The atomization assembly includes a housing, a bracket, an atomization core, and a ventilation component. A receiving cavity is formed inside the housing. The receiving cavity has an air inlet and an air outlet that communicate with the outside atmosphere. The bracket is disposed in the receiving cavity, and a heating cavity is formed inside the bracket. The housing and the bracket together form a main air passage, a liquid inlet passage, and a receiving passage. The main air passage communicates with the air inlet and the air outlet. The liquid inlet passage is used to communicate with the liquid storage cavity of the atomizer. The receiving passage is located between the bracket and the housing. The atomization core is disposed in the main air passage and is used to adsorb the atomization matrix from the liquid inlet passage and atomize it to generate an aerosol. A ventilation passage that communicates with the liquid inlet passage and the main air passage is formed on the ventilation component. The ventilation component is disposed in the receiving passage and does not enter the liquid inlet passage. In this embodiment, a receiving passage is formed between the housing and the bracket, which can balance the pressure in the liquid storage cavity in a timely manner. The ventilation component is disposed between the housing and the bracket, does not directly contact the atomization core, and does not enter the liquid inlet passage, which can reduce the atomization matrix contacted by the ventilation component, improve the anti-corrosion performance, and does not affect the ventilation effect after long-term use.

[0036] Please refer to Figures 1 to 8 , in this embodiment, the atomization assembly 100 mainly includes a housing 10, a bracket 20, an atomization core 30, and a ventilation component 40.

[0037] As Figures 1 to 3 shown, the housing 10 may include components that can be understood as the overall external contour of the atomization assembly 100. A receiving cavity 11 is formed inside it. The receiving cavity 11 is used to accommodate other components of the atomization assembly 100. The receiving cavity 11 has an air inlet 12 and an air outlet 13 that communicate with the outside atmosphere. The air inlet 12 and the air outlet 13 will also communicate with the main air passage 101 of the atomization assembly 100. In some embodiments, the air outlet 13 of the receiving cavity 11 may also be the air outlet opening of the main air passage 101, and the air inlet 12 of the receiving cavity 11 may also be the air inlet opening of the main air passage 101.

[0038] The bracket 20 is located in the receiving cavity 11. The bracket 20 is a component for installing the atomization core 30. The heating cavity 21 of the bracket 20 is used to set the atomization core 30. During the production process, the atomization core 30 can be first installed on the bracket 20, and then the bracket 20 with the atomization core 30 installed is integrally set into the receiving cavity 11.

[0039] The atomization assembly 100 has a main air passage 101, a liquid inlet passage 102, and a receiving passage 103. The main air passage 101, the liquid inlet passage 102, and the receiving passage 103 are jointly formed by the housing 10 and the bracket 20.

[0040] Among them, the main airway 101 serves as the main flow channel for the gas driving the aerosol and the aerosol. The main airway 101 can be arranged to penetrate the atomizing component 100. The main airway 101 can include the area restricted by the inner wall of the bracket 20 and the area restricted by the inner wall of the remaining area of the outer shell 10 (i.e., the area where the bracket 20 is not provided). The heating chamber 21 of the bracket 20 can also be regarded as a part of the main airway 101; the gas entering from the air inlet 12 moves in the direction of the air outlet 13 and drives the generated aerosol to be discharged from the air outlet 13. Refer to Figure 4 As shown, the path of the main airway 101 is schematically shown by a dotted line with an arrow, where the arrow direction reflects the gas flow direction.

[0041] The liquid inlet channel 102 is used to communicate with the liquid storage cavity 202 of the atomizer 200, and the atomizing matrix is stored in the liquid storage cavity 202 of the atomizer 200. The atomizing matrix will be provided to the atomizing core 30 through the liquid inlet channel 102. In this embodiment, the atomizing core 30 is arranged in the main airway 101. The atomizing core 30 is communicated with the liquid inlet channel 102, can adsorb the atomizing matrix entering from the liquid inlet channel 102, and heat the adsorbed atomizing matrix when powered on to generate aerosol. As the atomizing core 30 continuously works, the atomizing matrix adsorbed by the atomizing core 30 will be continuously consumed, and through the liquid inlet channel 102, the atomizing matrix stored in the liquid storage cavity 202 of the atomizer 200 can be replenished to the atomizing core 30.

[0042] The accommodating channel 103 communicates the liquid inlet channel 102 with the main airway 101 and is used to enable the gas to enter the liquid storage cavity 202 of the atomizer 200 through the liquid inlet channel 102. The accommodating channel 103 can enable the gas in the liquid inlet channel 102 to communicate with the outside atmosphere. As the atomizing matrix stored in the liquid storage cavity 202 of the atomizer 200 is consumed, a negative pressure will be formed in the liquid storage cavity 202 of the atomizer 200, and the gas can enter the liquid storage cavity 202 of the atomizer 200 in sequence through the accommodating channel 103 and the liquid inlet channel 102 to balance the pressure therein. The accommodating channel 103 is located between the bracket 20 and the outer shell 10, so that the air exchange member 40 is outside the heating chamber 21 and will not be in direct contact with the atomizing core 30. The air exchange member 40 is not in contact with the atomizing matrix adsorbed by the atomizing core 30, has better anti-corrosion performance, and also ensures the air exchange performance, and does not affect the air exchange effect after long-term use. Refer to Figure 4 , and the positions of the liquid inlet channel 102 and the accommodating channel 103 are schematically shown by a dotted line frame.

[0043] In some embodiments, the heating chamber 21 penetrates the bracket 20, and the heating chamber 21 has opposite ends, namely an air outlet end 22 and an air inlet end 23. The air outlet end 22 is the end closer to the air outlet 13, and the air inlet end 23 is the end farther from the air outlet 13. The bracket 20 can be tubular or other structures that can form a cavity inside as the heating chamber 21.

[0044] The heating chamber 21 can be the area defined by the inner wall of the bracket 20, and there is a gap between the outer wall of the bracket 20 and the inner wall of the housing 10, so as to cooperate to form a receiving channel 103. The receiving channel 103 has a first end 1031 and a second end 1032 that are connected and communicated. Among them, the first end 1031 is closer to the air outlet 13 than the second end 1032. Exemplarily, the first end 1031 of the receiving channel 103 can be formed by the cooperation of the inner wall of the housing 10 and the outer wall of the bracket 20 at the air outlet end 22 to communicate with the main air duct 101. The second end 1032 of the receiving channel 103 communicates with the liquid inlet channel 102. When a negative pressure is to be formed in the liquid storage chamber 202, the gas of the outside atmosphere can enter the receiving channel 103 through the first end 1031 of the receiving channel 103, enter the liquid inlet channel 102 through the second end 1032 of the receiving channel 103, and supplement the gas into the liquid storage chamber 202 through the liquid inlet channel 102 to achieve air pressure balance. By forming the receiving channel 103 through the cooperation of the outer wall of the bracket 20 and the inner wall of the housing 10, its structure is simple, and the receiving channel 103 can be naturally formed after the bracket 20 and the housing 10 are assembled, which is easy to manufacture.

[0045] In some embodiments, in combination with Figure 3 and Figure 5 , the bracket 20 includes an inner liquid inlet 24, and the inner liquid inlet 24 penetrates the side wall of the bracket 20 to communicate the atomization core 30 and the liquid inlet channel 102. The atomization core 30 can be arranged at the inner liquid inlet 24 and can cover the inner liquid inlet 24 to adsorb the atomization matrix entering from the inner liquid inlet 24 and prevent the atomization matrix from directly entering the heating chamber 21. The housing 10 includes an outer liquid inlet 14, and the outer liquid inlet 14 penetrates the side wall of the housing 10 for communicating the liquid inlet channel 102 and the liquid storage chamber 202 of the atomizer 200. There is a gap between the outer liquid inlet 14 and the inner liquid inlet 24, and this gap is also in the area between the bracket 20 and the housing 10. The gap between the outer liquid inlet 14 and the inner liquid inlet 24 can be regarded as a part of the liquid inlet channel 102. The atomization matrix stored in the liquid storage chamber 202 of the atomizer 200 can sequentially pass through the outer liquid inlet 14, the gap between the outer liquid inlet 14 and the inner liquid inlet 24, and the inner liquid inlet 24 to reach the atomization core 30. The second end 1032 of the receiving channel 103 communicates with the liquid inlet channel 102 at the gap between the outer liquid inlet 14 and the inner liquid inlet 24. After the gas for ventilation enters the liquid inlet channel 102, it can be supplemented into the liquid storage chamber 202 of the atomizer 200 through the outer liquid inlet 14. There is no additional blockage in this path, ensuring smooth ventilation. As Figure 5 shown, the path and direction of the gas flow for ventilation are indicated by arrows.

[0046] In some embodiments, the bracket 20 includes a mounting portion 25. The mounting portion 25 may be located on the outer wall of the end of the bracket 20 close to the air inlet 12, that is, on the outer wall at the air inlet end 23. The mounting portion 25 abuts against the inner wall of the housing 10 to mount the bracket 20 within the housing 10, and an interference fit may be formed between the mounting portion 25 and the air inlet end 23. The mounting portion 25 is used to connect the bracket 20 to the housing 10 so that the bracket 20 is fixed to the housing 10.

[0047] In this embodiment, there is a gap between the bracket 20 and the housing 10, but a seal can be formed at the position of the mounting portion 25. This makes the gap between the bracket 20 and the housing 10 not vertically through (i.e., through in the direction of the air outlet end 22 and the air inlet end 23 of the heating chamber 21). The mounting portion 25 seals the gap between the outer wall at the air inlet end 23 and the housing 10, which can prevent the atomization matrix from directly leaking through the gap between the bracket 20 and the housing 10. Moreover, this enables the accommodation channel 103 to be formed at a position close to the air outlet end 22. When the atomization assembly 100 is in use, the air outlet 13 generally faces upward in the direction of gravity. Under the action of gravity, it can better prevent the atomization matrix from leaking from the accommodation channel 103, and the gas can also easily pass through the accommodation channel 103 to ensure smooth air exchange.

[0048] In other embodiments, the gap between the outer wall of the bracket 20 at the air inlet end 23 of the heating chamber 21 and the housing 10 can also be used as the accommodation channel 103 or a part of the accommodation channel 103. The inner wall of the air inlet 12 of the housing 10 and the outer wall of the bracket 20 at the air inlet end 23 of the heating chamber 21 cooperate to form one end of the accommodation channel 103 for air intake. In these embodiments, the air exchange member 40 can be used to block the accommodation channel 103 to prevent the atomization matrix from directly leaking.

[0049] In some embodiments, the accommodation channel 103 has a mounting and positioning structure 26. The mounting and positioning structure 26 is used to limit the position of the air exchange member 40, which is used to ensure the accurate installation position of the air exchange member 40, thereby ensuring its air exchange performance and facilitating production. In the process of automated production, setting the mounting and positioning structure 26 can assist in positioning the installation of the air exchange member 40, which is beneficial to production. The mounting and positioning structure 26 is arranged inside the accommodation channel 103, and it can contact the air exchange member 40 to prevent the air exchange member 40 from shifting out of its position and entering the liquid inlet channel 102 or other positions. The air exchange member 40 is arranged on the side of the mounting and positioning structure 26 away from the liquid inlet channel 102, which can prevent the air exchange member 40 from shifting towards the side of the liquid inlet channel 102. The mounting and positioning structure 26 is closer to the first end 1031 than the liquid inlet channel 102, so that the air exchange member 40 is arranged in a direction closer to the first end 1031. Since the first end 1031 generally faces upward in the direction of gravity during use, it can reduce the contact between the air exchange member 40 and the atomization matrix to a greater extent and has better anti-corrosion performance.

[0050] In some embodiments, the installation and positioning structure 26 is provided on the outer wall of the bracket 20. As shown in combination with Figure 3 and Figure 6 , the installation and positioning structure 26 protrudes towards the inner wall of the housing 10 to form a tabletop, and together with the inner wall of the housing 10, it defines the second end 1032 of the accommodation channel 103. The ventilation member 40 has opposite ends. One end of the ventilation member 40 is close to the air outlet 13, and the other end of the ventilation member 40 contacts the tabletop. The outwardly protruding installation and positioning structure 26 is easy to manufacture, and the structure is simple and reliable. During the production process, the ventilation member 40 can be first installed on the bracket 20. At this time, the installation and positioning structure 26 can ensure the accurate installation position of the ventilation member 40, which is beneficial to the automated production process.

[0051] In other embodiments, the installation and positioning structure 26 can also be formed as a groove. When the ventilation member 40 is installed, it partially enters the groove to achieve positioning. Or the installation and positioning structure 26 can also be set in other forms. And in other embodiments, the installation and positioning structure 26 can also be provided on the inner wall of the housing 10, or formed by the cooperation of the outer wall of the bracket 20 and the inner wall of the housing 10. For example, the installation and positioning structure 26 is formed on the inner wall of the housing 10 and protrudes towards the side of the bracket 20 to form a tabletop, and together with the outer wall of the bracket 20, it defines the second end 1032 of the accommodation channel 103.

[0052] It can be understood that the installation and positioning structure 26 is located within the accommodation channel 103, and it can occupy the internal space of the accommodation channel 103, thereby changing the internal structure of the accommodation channel 103. In some embodiments, the second end 1032 of the accommodation channel 103 is formed by the cooperation of the installation and positioning structure 26 with the housing 10 or the bracket 20, and is used to communicate with the liquid inlet channel 102. That is, the installation and positioning structure 26 can serve as a part of the accommodation channel 103. The protruding installation and positioning structure 26 can make the second end 1032 of the accommodation channel 103 narrower. In this embodiment, the cross-sectional area of the second end 1032 of the accommodation channel 103 is smaller than the cross-sectional area of its first end 1031. The second end 1032 of the accommodation channel 103 is the end that communicates with the liquid inlet channel 102. By reducing the cross-sectional area of the second end 1032 of the accommodation channel 103, it is possible to hinder the atomization matrix from entering the accommodation channel 103 to a certain extent and reduce the possibility of atomization matrix leakage. At the same time, hindering the atomization matrix from entering the accommodation channel 103 can also reduce the atomization matrix contacted by the ventilation member 40 and improve the anti-corrosion performance. It can be understood that gas is more likely to pass through various narrow gaps than liquid. In practical applications, the cross-sectional area of the second end 1032 of the accommodation channel 103 can be controlled within a suitable range to hinder the atomization matrix from entering the accommodation channel 103 without affecting the ventilation performance.

[0053] Inside the atomization core 30 in this embodiment, an air flow channel for the entry and exit of air flow and aerosol can be formed, and this air flow channel can also be regarded as a part of the main air duct 101. By using the atomization core 30 to heat and atomize the atomization matrix to produce aerosol, the generated aerosol can be discharged from the air flow channel along with the air flow for use.

[0054] The atomization core 30 can include a liquid guiding member 31 and a heating member 32. The liquid guiding member 31 is used to guide the atomization matrix and has a certain liquid storage function. The liquid guiding member 31 can be a porous matrix such as liquid guiding cotton, and the porous structure therein is used to guide the atomization matrix; the liquid guiding member 31 can also be other structures capable of guiding the atomization matrix. The air flow channel is formed by surrounding the liquid guiding member 31 and penetrates through the liquid guiding member 31. The heating member 32 can be arranged in the air flow channel, and the heating member 32 is used to heat the atomization matrix adsorbed by the liquid guiding member 31 when powered on to generate aerosol.

[0055] The air exchange member 40 is arranged in the accommodation channel 103. In some embodiments, the air exchange member 40 forms a blockage for the accommodation channel 103 to prevent direct communication between the liquid inlet channel 102 and the main air duct 101, thereby preventing the atomization matrix from directly leaking from the liquid inlet channel 102 to the main air duct 101 or the outside through the accommodation channel 103. It should be noted that the blockage of the accommodation channel 103 by the air exchange member 40 is air-permeable, and an air exchange channel 41 is formed on the air exchange member 40, and the air exchange channel 41 connects the accommodation channel 103 and the main air duct 101. That is to say, the air exchange member 40 is used to block the atomization matrix from passing through, but allows gas to pass through. It should be noted that the obstruction of the atomization matrix by the air exchange member 40 can completely prevent the atomization matrix from passing through, or can slow down the passing speed of the atomization matrix or increase the difficulty of the atomization matrix passing through.

[0056] In addition, the air exchange member 40 of this embodiment does not enter the liquid inlet channel 102, that is, as Figure 3 shown, the air exchange member 40 is arranged to avoid the outer liquid inlet 14 and the inner liquid inlet 24, and does not cover and block the outer liquid inlet 14, the inner liquid inlet 24 and the area between them. This enables the atomization matrix to flow more smoothly in the liquid inlet channel 102, ensuring the smooth supply of the atomization matrix. And it is beneficial to reduce the atomization matrix contacted by the air exchange member 40, and it will have good anti-corrosion performance.

[0057] As an example, see Figure 8, micropores are formed in the air exchange member 40, and the micropores can serve as an air exchange channel 41 to allow gas to pass through. When the atomization matrix contacts the air exchange member 40, the atomization matrix can enter the micropores, and the atomization matrix forms a liquid film on the surface of the micropores, which can form an obstacle to the passage of the atomization matrix. When a negative pressure is formed in the liquid storage cavity 202 of the atomizer 200, the liquid film on the surface of the micropores breaks, enabling the gas to pass through. The air exchange channel 41 in the air exchange member 40 can be an irregular air-permeable structure composed of a large number of micropores, or a channel that penetrates along the directions of the first end 1031 and the second end 1032 of the accommodation channel 103.

[0058] In the related art, the air exchange member 40 can be a cotton sheet coil, that is, a multi-layer structure formed by coiling a cotton sheet, and the gaps between the cotton sheets are used for air permeability, and can adsorb and obstruct the passage of the atomization matrix to a certain extent. In some embodiments, the air exchange member 40 is an integrally formed structure. The integrally formed structure replaces the cotton sheet coil, which is more conducive to automated assembly, and the stability and consistency of the structure of the air exchange member 40 itself are better, thereby ensuring the air exchange performance and quality of the atomization assembly 100.

[0059] In some embodiments, the air exchange member 40 can be made of a plastic material such as plastic and formed into an integrally formed structure. The plastic material has a weak adsorption property for the atomization matrix and less contact with the atomization matrix, so it has good anti-corrosion properties. In some embodiments, the air exchange member 40 uses an integrated cotton, which can be formed according to the required shape without manual winding. The material of the integrated cotton can specifically be existing composite materials such as PA (polyamide) + PET (polyester) or PE (polyethylene) + PET (polyester).

[0060] In some embodiments, as Figure 8 shown, the air exchange member 40 can be a hollow tubular structure, which is simple and easy for automated production. During installation, the air exchange member 40 can be directly sleeved on the bracket 20, which is conducive to the automated assembly process. The accommodation channel 103 can surround the outer wall of the bracket 20. Taking the bracket 20 as a cylindrical tube, the shape of the accommodation channel 103 is annular. For example, except for the parts that need to be connected and fixed such as the installation part 25, the outer wall of the bracket 20 and the inner wall of the housing 10 may not be in contact.

[0061] In some embodiments, the air exchange member 40 and the outer wall of the bracket 20 can be in interference fit, that is, the inner diameter of the air exchange member 40 is slightly smaller than the outer diameter of the bracket 20. The stable installation of the air exchange member 40 and the bracket 20 can avoid position deviation during subsequent processing, facilitate automated processing, and ensure product quality. In addition, there can also be an interference fit between the air exchange member 40 and the inner wall of the housing 10, that is, the outer diameter of the air exchange member 40 is slightly larger than the inner diameter of the outer diameter. Ensure that the air exchange member 40 can effectively block the accommodation channel 103, and avoid forming a gap between the air exchange member 40 and the inner wall of the housing 10, thereby preventing the atomization matrix from leaking directly to the outside.

[0062] In some embodiments, an atomizer 200 is also provided. Refer to Figure 9 As shown, it mainly includes an atomizer housing 201 and an atomization assembly 100.

[0063] The atomizer housing 201 is provided with a liquid storage cavity 202 inside, and the liquid storage cavity 202 is used to store the atomization matrix. The atomization assembly 100 is the atomization assembly 100 provided in any of the foregoing embodiments. It is disposed inside the atomizer housing 201, and the liquid inlet channel 102 communicates with the liquid storage cavity 202.

[0064] In some embodiments, an electronic atomization device is also provided, including the atomizer 200 and a power supply assembly in the above embodiments. The atomization assembly 100 is electrically connected to the power supply assembly.

[0065] The power supply assembly is used to supply electrical energy to the atomization core 30 in the atomization assembly 100. The atomization core 30 and the power supply assembly can be fixedly connected or detachably connected. The above electronic atomization device is only one embodiment of the present application, and the specific internal structure of the electronic atomization device will not be elaborated.

[0066] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art of the present invention, several simple deductions, deformations or substitutions can be made according to the idea of the present invention.
