PRIORITY INFORMATION

[0002] The present disclosure relates to the field of atomization device technologies, and more particularly, to an atomizer.BACKGROUND

[0003] In the related art, an atomization core of an atomizer is generally manufactured by winding a metallic heating element around ceramic. Limited by miniaturization requirements of the atomizer, the atomization core generally has a small volume. Consequently, the atomization core has a small heating area, which results in a low atomization efficiency and constrained atomization performance. However, when heating power is increased, an energy density of an atomization surface is high due to a small area of the atomization surface, in such a manner that an atomization temperature is easy to be too high. As a result, a risk of burnt core due to overheating of the atomization core is likely to occur, which affects a service life of the product.SUMMARY

The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limit, the present disclosure.

[0025] A number of embodiments or examples are provided in the disclosure of the present disclosure to implement different structures of the embodiments of the present disclosure. To simplify the disclosure of the embodiments of the present disclosure, components and arrangements of particular examples will be described below, which are, of course, examples only and are not intended to limit the present disclosure. Further, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present disclosure. Such repetition is for the purpose of simplicity and clarity and does not indicate any relationship between various embodiments and / or arrangements in question. In addition, various examples of specific processes and materials are provided in the embodiments of the present disclosure. However, those of ordinary skill in the art may be aware of applications of other processes and / or the use of other materials.

[0026] As illustrated in FIG. 1 to FIG. 3, according to an embodiment of the present disclosure, an atomizer 100 is provided. The atomizer 100 includes a base 10, an atomization cover 20, and a heating assembly 30.

[0027] The atomization cover 20 is mounted at the base 10. An atomization cavity 50 is formed between the atomization cover 20 and the base 10. The heating assembly 30 is fixed to the base 10 and located in the atomization cavity 50. The heating assembly 30 includes an atomization core 304 and a heating member 301. The atomization core 304 includes two atomization surfaces 3044 that are opposite to each other. The heating member 301 is arranged at each of the two atomization surfaces 3044.

[0028] In the above atomizer 100, the atomization core 304 has the two atomization surfaces 3044 that are opposite to each other, which enlarge a heating area and make the atomizer 100 suitable for high heating power. In addition, the two atomization surfaces 3044 enable uniform heating, which can avoid a risk of burnt core to a great extent and improve a heating efficiency of the heating assembly 30, achieving satisfactory atomization performance.

[0029] Specifically, the atomization cover 20 is mounted at the base 10. The atomization cavity 50 is formed between the atomization cover 20 and the base 10. The heating assembly 30 is fixed to the base 10 and located in the atomization cavity 50. The heating assembly 30 includes the atomization core 304 and the heating member 301. The atomization core 304 includes the two atomization surfaces 3044 that are opposite to each other. The heating member 301 is arranged at each of the two atomization surfaces 3044. In this way, the heating area of the atomization core 304 is enlarged, which improves a heating efficiency, making the atomizer 100 suitable for high heating power. In addition, arranging the heating member 301 at each of the two atomization surfaces 3044 enables the uniform heating of the two atomization surfaces 3044, which can effectively avoid the risk of burnt core and improve the heating efficiency of the heating assembly 30, achieving the satisfactory atomization performance.

[0030] In some embodiments, the base 10 has an atomization cavity inlet 501. The atomization cover 20 has an atomization cavity outlet 502. Each of the two atomization surfaces 3044 is substantially parallel to a line connecting a center point of the atomization cavity inlet 501 and a center point of the atomization cavity outlet 502.

[0031] In this way, a flow path of an atomized gas can be shortened to improve a gas exhaust efficiency of the atomizer 100.

[0032] Specifically, as illustrated in FIG. 1 and FIG. 2, the heating assembly 30 is located in the atomization cavity 50 and includes the atomization core 304. The atomization core 304 includes the two atomization surfaces 3044. The heating member 301 is arranged at each of the two atomization surfaces 3044. The atomization cover 20 has the atomization cavity outlet 502. Each of the two atomization surfaces 3044 is substantially parallel to the line connecting the center point of the atomization cavity inlet 501 and the center point of the atomization cavity outlet 502. After an atomization liquid is atomized by the atomization surfaces 3044 into the atomized gas, the atomized gas may flow directly towards the atomization cavity outlet 502. As illustrated in FIG. 1, the dotted line in the figure illustrates a gas path in the atomizer 100, and the arrow of the dotted line illustrates a flow direction of the atomized gas. The atomized gas may flow directly upwards, which shortens the flow path of the atomized gas. In this way, large aerosol particles in the atomized gas can be retained, and the gas exhaust efficiency of the atomizer 100 can be improved.

[0033] In an embodiment, the atomization core 304 may be made of ceramic. The atomization core 304 made of ceramic is sintered integrally with the heating member 301. The ceramic not only enables the atomization core 304 to have satisfactory thermal conductivity and satisfactory atomization performance, but also provides guiding and storage for the atomization liquid. In other embodiments, the atomization core 304 may also be made of any one or any combination of ceramic, semiconductor ceramic, and silicon carbide.

[0034] In some embodiments, the atomization core 304 is in a substantially rectangular shape, includes a top surface facing the atomization cover 20, and has a liquid storage groove 3041 at the top surface of the atomization core 304. The two atomization surfaces 3044 are arranged at two sides of the liquid storage groove 3041, respectively.

[0035] In this way, the liquid storage groove 3041 is configured to store and guide the atomization liquid, which can improve an atomization efficiency.

[0036] Specifically, as illustrated in FIG. 3 and FIG. 4, the atomization core 304 is in the substantially rectangular shape. The top surface of the atomization core 304 faces the atomization cover 20. The liquid storage groove 3041 is defined at the top surface of the atomization core 304 and configured to store and guide the atomization liquid. The two atomization surfaces 3044 are arranged at the two sides of the liquid storage groove 3041, respectively, which enables the atomization liquid to be in full contact with the atomization surfaces 3044 to further avoid an occurrence of the burnt core caused by inadequate guiding of the atomization liquid, facilitating an improvement of the atomization efficiency of the atomization core 304.

[0037] In some embodiments, the atomization core 304 further includes two side end faces 3042 that are opposite to each other. Each of the two side end faces 3042 is connected substantially perpendicularly to the top surface and the two atomization surfaces 3044. The liquid storage groove 3041 is a through groove in a substantially rectangular shape and extends through the two side end faces 3042 in a direction substantially parallel to the two atomization surfaces 3044.

[0038] In this way, the liquid storage groove 3041 provides uniform liquid guiding.

[0039] Specifically, as illustrated in FIG. 4, the atomization core 304 further includes the two side end faces 3042 that are opposite to each other. Each of the two side end faces 3042 is connected substantially perpendicularly to the top surface and the two atomization surfaces 3044. The liquid storage groove 3041 is the through groove in the substantially rectangular shape and extends through the two side end faces 3042 in the direction substantially parallel to the two atomization surfaces 3044. The structure of the through groove can enlarge a liquid storage area and make the atomization liquid flow uniformly within the liquid storage groove 3041, in such a manner that the atomization liquid is uniformly distributed at the atomization core 304 for atomization, improving the atomization performance.

[0040] In some embodiments, the atomization core 304 includes a connection bridge 3043 connected to two sides of the through groove.

[0041] In this way, mechanical strength of the atomization core 304 is strengthened.

[0042] Specifically, the atomization core 304 includes a connection bridge 3043 configured to connect two sides of the through groove where the two atomization surfaces 3044 are located. As illustrated in FIG. 5, the connection bridge 3043 can strengthen the mechanical strength of the atomization core 304 and reduce a risk of the atomization core 304 fracturing during use.

[0043] In some embodiments, the atomizer 100 further includes a conductive assembly 40. The conductive assembly 40 includes a conductive post 401 and an elastic sheet 402. The conductive post 401 is configured to be connected to a power source of the atomizer 100. The conductive post 401 is fixed to the base 10. A part of the conductive post 401 extends into the atomization cavity 50. The elastic sheet 402 includes a first free end 4021 and a mounting portion 4023. The mounting portion 4023 is fixed to the conductive post 401. The first free end 4021 elastically abuts with the heating member 301.

[0044] In this way, the first free end 4021 abuts with the heating member 301 and a fixation is realized through the mounting portion 4023, realizing easy mounting and a stable connection.

[0045] Specifically, as illustrated in FIG. 6, the conductive assembly 40 includes the conductive post 401 and the elastic sheet 402. The conductive post 401 is fixed to the base 10. When the base 10 is connected to the power source of the atomizer 100, the conductive post 401 can be connected to the power source. The elastic sheet 402 is fixed to the part of the conductive post 401 extending into the atomization cavity 50. Two first free ends 4021 of the elastic sheet 402 are capable of connecting the heating members 301 at the two atomization surfaces 3044 in parallel and being energized through contact with the conductive post 401 to realize an electrical connection of the heating member 301 to the power source. During mounting, the conductive post 401 is fixed to the base 10, the elastic sheet 402 is fixed to the conductive post 401, and the atomization core 304 is mounted towards the base 10 to elastically abut with the elastic sheet 402. Therefore, the mounting is completed, which is simple and convenient and provides the stable connection.

[0046] In some embodiments, the elastic sheet 402 includes a first bent portion 4024. The first bent portion 4024 bends from the mounting portion 4023 towards a center of the atomization cavity 50. An end of the first bent portion 4024 close to the atomization cover 20 is formed as the first free end 4021.

[0047] In this way, manufacturing and molding of the elastic sheet 402 can be facilitated.

[0048] Specifically, as illustrated in FIG. 4, the elastic sheet 402 includes the first bent portion 4024 and the mounting portion 4023. The first bent portion 4024 bends from the mounting portion 4023 towards the center of the atomization cavity 50. The end of the first bent portion 4024 close to the atomization cover 20 is formed as the first free end 4021. In this way, the elastic sheet 402 can be integrally formed, which facilitates the manufacturing.

[0049] In some embodiments, the heating member 301 includes a heating segment 3011 and an electrode segment 3012 located at each of two ends of the heating segment 3011. The elastic sheet 402 is configured such that the mounting portion 4023 is fixedly connected to the conductive post 401 and the first free end 4021 elastically abuts with the electrode segment 3012 when the atomization cover 20 is mounted at the base 10.

[0050] In this way, the electrode segment 3012 is configured to be connected to the power source, and the heating segment 3011 is in contact with the atomization surface 3044 and configured to heat the atomization surface 3044, to realize an electrical connection between the heating member 301 and the power source.

[0051] Specifically, as illustrated in FIG. 6, the heating member 301 includes the heating segment 3011 and the electrode segment 3012 located at each of the two ends of the heating segment 3011. The electrode segment 3012 is configured to abut with the first free end 4021 when the atomization core 304 is mounted at the conductive assembly 40. Therefore, the electrical connection between the heating member 301 and the power source is realized. The heating segment 3011 is in contact with the atomization surface 3044 and is configured to heat the atomization surface 3044 for atomization.

[0052] In some embodiments, the heating segment 3011 is in a serpentine shape.

[0053] In this way, a contact area between the heating member 301 and the atomization core 304 can be enlarged.

[0054] Specifically, as illustrated in FIG. 6, the two ends of the heating segment 3011 are connected to the electrode segments 3012, respectively. The heating segment 3011 may be in a serpentine shape to enlarge the contact area with the atomization surface 3044, improving a heat transfer efficiency. In other embodiments, the heating segment 3011 may be designed in other shapes that can enlarge the contact area with the atomization surface 3044. For example, the heating segment 3011 may be designed in an "N" shape or an "S" shape.

[0055] In some embodiments, the heating assembly 30 includes a silicone seal 306 located between the atomization cover 20 and the base 10 and wrapping the atomization core 304. The silicone seal 306 has a hollow part to expose the two atomization surfaces 3044.

[0056] In this way, the atomization cavity 50 can be ensured to have satisfactory sealing performance to prevent leakage of the atomization liquid.

[0057] Specifically, as illustrated in FIG. 1 and FIG. 2, the heating assembly 30 includes the silicone seal 306 located between the base 10 and the atomization cover 20 and wrapping the atomization core 304. In this way, an empty space between the atomization core 304 and the atomization cover 20 and the base 10 is filled with the silicone seal 306 to ensure the sealing performance of the atomization cavity 50. The silicone seal 306 has the hollow part to expose the two atomization surfaces 3044 to the atomization cavity 50, which facilitates atomization of the atomization liquid by the atomization surface 3044.

[0058] In some embodiments, the hollow part is in a rectangular shape.

[0059] In this way, a large area of the atomization surface 3044 can be exposed while maintaining the sealing performance.

[0060] Specifically, the hollow part of the silicone seal 306 is in the rectangular shape. That is, the silicone seal 306 wraps around corners of the atomization core 304 between the atomization cover 20 and the base 10 to improve the sealing performance of the atomization cavity 50, and to allow a large part of the atomization surface 3044 to be exposed to the atomization cavity 50, improving the atomization efficiency.

[0061] In some embodiments, the atomizer 100 further includes an upper housing 60. The upper housing 60 is connected to the base 10 and configured to enclose the atomization cover 20 between the upper housing 60 and the base 10. The atomization cavity 50 is defined by a bottom of the atomization cover 20 and a top of the base 10. The upper housing 60 has an air outlet 601 and an air outlet segment 602. The atomization cover 20 has an atomization cover gas passage 201 in communication with an atomization cavity outlet 502 and the air outlet segment 602. The base 10 has an air inlet 101 and an air inlet segment 102. The air inlet segment 102 is in communication with the air inlet 101 and the atomization cavity 50.

[0062] In this way, the atomization cavity 50, the air inlet 101, and the air outlet 601 are in communication with each other to form the gas path in the atomizer 100.

[0063] Specifically, as illustrated in FIG. 2 and FIG. 3, the atomizer 100 further includes the upper housing 60. The upper housing 60 is connected to the base 10 and configured to enclose the atomization cover 20 between the upper housing 60 and the base 10. The atomization cavity 50 is defined by the bottom of the atomization cover 20 and the top of the base 10. The upper housing 60 has the air outlet 601 and the air outlet segment 602. The atomization cover 20 has the atomization cover gas passage 201. As illustrated in FIG. 2 and FIG. 3, the atomization cover gas passage 201 is in communication with the atomization cavity outlet 502 and the air outlet segment 602. The base 10 has the air inlet 101 and the air inlet segment 102. The air inlet segment 102 is in communication with the air inlet 101 and the atomization cavity 50. In this way, the gas path in the atomizer 100 is formed. Air enters the atomizer 100 from the air inlet segment 102. The atomization liquid is heated in the atomization cavity 50 through the heating assembly 30 to generate the atomized gas. The atomized gas in the atomization cavity 50 flows upwardly out of the atomization cavity outlet 502, passes through the atomization cover gas passage 201 and the air outlet segment 602, and finally flows out from the air outlet 601. Therefore, an atomization process of the atomization liquid is completed.

[0064] In some embodiments, the upper housing 60 has a liquid storage cavity 603 and a liquid discharge hole 604 in communication with the liquid storage cavity 603. The liquid storage cavity 603 is configured to store an atomization liquid. The heating assembly 30 includes the atomization core 304. The atomization cover 20 has a liquid inlet hole 202 in communication with the liquid discharge hole 604 and the atomization core 304.

[0065] In this way, the atomization liquid is stored and supplied to the atomization core 304 via the liquid storage cavity 603.

[0066] Specifically, as illustrated in FIG. 1 and FIG. 3, the upper housing 60 has the liquid storage cavity 603 and the liquid discharge hole 604 in communication with the liquid storage cavity 603. The atomization cover 20 has the liquid inlet hole 202. The liquid discharge hole 604 and the liquid inlet hole 202 are formed at positions corresponding to each other. The atomization liquid flows downwardly from the liquid storage cavity 603, and is capable of flowing onto the atomization core 304 for atomization through the liquid discharge hole 604 and the liquid inlet hole 202.

[0067] In some embodiments, the atomizer 100 further includes a silicone atomization cover pad 80 arranged between the upper housing 60 and the atomization cover 20.

[0068] In this way, sealing between the upper housing 60 and the atomization cover 20 can prevent leakage of the atomization liquid when the atomization liquid flows into the atomization cavity 50.

[0069] Specifically, as illustrated in FIG. 1 to FIG. 3, the atomizer 100 further includes the silicone atomization cover pad 80 arranged between the upper housing 60 and the atomization cover 20. The silicone atomization cover pad 80 is located on the atomization cover 20 and has a hole at a position corresponding to the liquid storage cavity 603. The silicone atomization cover pad 80 is used for sealing between a periphery of the liquid discharge hole 604 formed at the upper housing 60 and a periphery of the liquid inlet hole 202 formed at the atomization cover 20 to prevent the leakage of the atomization liquid.

[0070] In some embodiments, the atomizer 100 further includes a silicone base pad 70 arranged between the base 10 and the atomization cover 20.

[0071] In this way, a connection between the base 10 and the atomization cover 20 can be sealed to ensure the sealing performance of the atomization cavity 50.

[0072] Specifically, as illustrated in FIG. 1 to FIG. 3, the atomizer 100 further includes the silicone base pad 70 arranged between the base 10 and the atomization cover 20. The silicone base pad 70 is arranged around the base 10 during the mounting. As illustrated in FIG. 1, during the mounting, the upper housing 60 is tightly pressed downwards against the atomization cover 20. The atomization cover 20 is fixed between the upper housing 60 and the base 10. A bottom surface of the atomization cover 20 is tightly pressed against the silicone base pad 70. Therefore, the atomization cavity 50 can be ensured to have the satisfactory sealing performance to prevent leakage of the atomized gas or the leakage of the atomization liquid.

[0073] In summary, for the atomizer 100 according to the embodiments of the present disclosure, the two atomization surfaces 3044 opposite to each other are provided for fixing the heating member 301, which enlarges the heating area of the atomization core 304, effectively improving the heating efficiency. Therefore, the atomization efficiency is improved. In addition, the atomization core 304 has the liquid storage groove 3041. The liquid storage groove 3041 provides liquid storage and liquid guiding, which can enable the atomization liquid to be in full contact with the atomization surface 3044 to be converted into the atomized gas, enhancing the atomization efficiency.

[0074] Further, by setting the atomization surface 3044 substantially parallel to a direction of the gas path of the atomizer 100, circuitousness of the gas path can be effectively reduced to improve a gas exhaust efficiency. After the atomization surfaces 3044 and the heating members 301 are arranged at side surfaces of the atomization core 304, the elastic sheets 402 elastically abut with the heating members 301 at two sides of the atomization core 304 through. During the mounting, the atomizer 100 may be mounted through performing stacking in a bottom-to-top direction illustrated in FIG. 1, which makes the processing and the mounting of the atomizer 100 convenient, facilitating automated manufacturing and an improvement of a manufacturing efficiency.
