Description

Technical Field

[0001] This invention belongs to the field of electronic atomization technology, and particularly relates to an atomizer. Background Technology

[0002] Some atomizers have an elliptical cross-section, so the heating area of ​​the heating element is roughly rectangular, and the corresponding wicking body is also rectangular. It has two heating channels that are connected to the two ends of the wicking body along its length. This results in a slower wicking speed in the center of the wicking body. For conventional heating elements, the heat is most concentrated in the center when heating, and the wicking body is consumed the fastest in the center area. This can easily lead to dry burning due to poor wicking and insufficient wicking supply. Summary of the Invention

[0013] Optionally, the heating element further includes a support body stacked on the top of the base, and the heating element is clamped and positioned between the support body and the oil guide body; the two ends of the support body are respectively provided with second mounting holes, and the support body is provided with clearance holes corresponding to the atomizing part, and the clearance holes are correspondingly connected to the atomizing cavity at the top of the base; the top ends of the two electrodes pass through the two mounting holes and abut against the two fixing parts.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] This invention provides an electronic atomization device, which includes a battery rod (not shown) and an atomizer. The battery rod contains a power supply and a control circuit. The control circuit controls the power supply to provide power to the atomizer. The atomizer includes an oil cup and an atomizing component installed in the oil cup.

[0031] Please see Figure 1 As shown, the oil cup 10 has an opening at the lower end and an air inlet 11 at the upper end for the user to inhale. An air guide tube 12 extending into the oil cup 10 is formed on the upper inner wall of the air inlet 11 along its periphery, and the interior of the air guide tube 12 communicates with the air inlet 11. A liquid storage chamber 13 is formed between the air guide tube 12 and the inner wall of the oil cup 10 to store the atomizing liquid. In this embodiment, the air guide tube 12 and the oil cup 10 are integrally formed.

[0032] Combination Figures 2 to 5As shown, the atomizing assembly includes a bottom assembly, a bracket 20, and a heating assembly 30. The bracket 20 is installed inside the open end of the oil cup 10 and is sealed to the inner wall of the oil cup 10 through a sealing member 21. The bottom assembly includes a base 41 installed in the lower opening of the oil cup 10 and two electrodes 42 inserted from bottom to top into the base 41 to supply power to the heating assembly 30. The lower end of the bracket 20 is sleeved on the upper end of the base 41, thereby clamping and positioning the heating assembly 30 between the base 41 and the bracket 20. The bracket 20 has an inlet channel 22 for supplying the atomizing liquid in the liquid storage chamber 13 to the heating assembly 30.

[0033] Combination Figure 5 As shown, the lower end of the bracket 20 is fitted onto the top end of the base 41 to clamp and fix the heating element 30 between the bracket 20 and the base 41. Specifically, the bracket 20 includes a top wall 23 and a side wall 24 extending downward along the periphery of the top wall 23. The side wall 24 is fitted onto the upper end of the base 41, and the liquid inlet channel 22 is formed vertically through the top wall 23. The top surface of the oil guide 31 abuts against the bottom surface of the top wall 23. In practical applications, the side wall 24 is fixed to the base 41 by screwing, plugging, or snap-fit ​​connection. In this embodiment, a snap-fit ​​connection is preferred, thereby clamping and fixing the heating element 30 between the bottom surface of the top wall 23 and the top surface of the base 41, so that the oil guide 31 fits tightly against the bottom surface of the top wall 23 to cover the lower end of the liquid inlet channel 22 and prevent oil leakage. In addition, this structure allows the heating element 30 and the bracket 20 to be stacked and installed sequentially on the top of the base 41 to form a fixed whole during the assembly of the atomizing component in this embodiment. Then, the whole atomizing component is assembled into the lower opening of the oil cup 10, making the assembly more convenient and faster and improving production efficiency.

[0034] Specifically, the support 20 has two liquid inlet channels 22, and the bottom surface of the top wall 23 is recessed to form a connecting groove 25 connecting the two liquid inlet channels 22. The top surface of the connecting groove 25 gradually slopes downwards along the direction close to the center of the connecting groove 25. This structure facilitates the rapid conduction of the atomizing liquid to the center of the heating element 30, thereby preventing the phenomenon of dry burning in the central area of ​​the heating element 30 due to slow oil conduction through the connecting groove 25.

[0035] The base 41 has mounting channels 411 extending through its top and bottom ends. Two electrodes 42 are inserted into the mounting channels 411 from bottom to top for fixed installation. The top ends of the two electrodes 42 are electrically connected to the heating element 30. The two electrodes 42 are used to connect to the positive and negative terminals of the power supply. The bottom ends of the two electrodes 42 are flush with or protrude from the bottom surface of the base 41, so that the atomizer can connect to the conductive contacts on the battery rod through the bottom ends of the two electrodes 42.

[0036] In one embodiment, the heating component 30 includes an oil guide body 31 and a heating element 32 stacked on top of the base 41. The oil guide body 31 and the heating element 32 are installed on the top of the base 41, and the oil guide body 31 is in close contact with the bottom surface inside the bracket 20, thereby connecting with the liquid inlet channel 22. The oil guide body 31 is a sheet made of oil-absorbing cotton, so the oil guide body 31 contains a large number of microporous structures and has a certain porosity, which can draw in the atomized liquid in the liquid storage chamber 13 and transfer it to the bottom surface in contact with the heating element 32, so that the heating element 32 heats and atomizes the contacted atomized liquid.

[0037] The top of the base 41 is provided with an atomizing cavity 412 corresponding to the atomizing part 322 of the heating element 32. Specifically, the top of the base 41 is recessed to form a space, which forms an atomizing cavity 412 between the base 41 and the oil guide body 31. The heating element 32 is preferably located on the side of the oil guide body 31 facing the atomizing cavity 412, so that the tops of the two electrodes 42 can be easily electrically connected to the two ends of the heating element 32 respectively.

[0038] It should be noted that the atomizing chamber 412 is connected to the air guide tube 12 of the oil cup 10 and the air inlet channel 414 at the bottom of the base 41. When the user inhales into the inlet 11, the heating element 32 heats and atomizes the atomized liquid absorbed in the oil guide body 31 to generate an aerosol that can be inhaled by the user in the atomizing chamber 412. At the same time, the air outside the atomizer enters into the atomizing chamber 412 through the air inlet channel 414 and mixes with the generated aerosol. After mixing, the air is finally inhaled by the user through the air guide tube 12 and the inlet 11.

[0039] Specifically, an air inlet pipe 413 extends protruding from the bottom of the atomizing chamber 412 towards the atomizing chamber 412, and an air inlet channel 414 communicating with the atomizing chamber 412 is formed inside the air inlet pipe 413. The air inlet pipe 413 and the base 41 are integrally formed. The air inlet pipe 413 is open at the bottom and has several air inlet holes 4131 at the top so that the air inlet channel 414 communicates with the atomizing chamber 412. Furthermore, since an annular collection groove (i.e., the bottom of the atomizing chamber 412) can be formed between the outer side of the air inlet pipe 413 and the inner side of the atomizing chamber 412, the atomizing liquid leaked from the heating element 30 and the condensate formed inside the atomizer can be stored through the annular collection groove, which can prevent the atomizing liquid or condensate from entering the atomizing chamber 412 and flowing out from the air inlet channel 414.

[0040] In one embodiment, a first return air groove 291 is formed on the inner side of the sidewall 24, and a second return air groove 292 connected to the first return air groove 291 is formed on the bottom surface of the top wall 23. The end of the second return air groove 292 away from the first return air groove 291 extends to the liquid inlet channel 22. The first return air groove 291 and the second return air groove 292 together form a return air channel 29. One end of the return air channel 29 is connected to the atomizing chamber 412, and the other end is connected to the liquid inlet channel 22. When the user inhales, the atomizing liquid in the liquid storage chamber 13 is absorbed and heated by the heating component 30, resulting in a negative pressure inside the liquid storage chamber 13. When the external air mixes with the aerosol, a portion of the gas enters the liquid storage chamber 13 from the formed return air channel 29 and through the liquid inlet channel 22, thereby balancing the air pressure inside the liquid storage chamber 13 and preventing poor oil flow.

[0041] Preferably, a mounting position 26 is formed in the middle of the top surface of the top wall 23, which is connected to the air guide tube 12 provided in the oil cup 10. An air passage chamber 27 is provided at the bottom of the top wall 23, and a through groove 28 is formed on the inner and outer surfaces of the side wall 24. The lower end of the through groove 28 extends to communicate with the atomizing chamber 412, and the upper end extends to communicate with the air passage chamber 27. It should be understood that the upper end of the base 41 has openings on opposite sides of the atomizing chamber 412 to allow the atomizing chamber 412 to communicate with the through groove 28 when the bracket 20 is fitted onto the base 41. Preferably, there are two through grooves 28, respectively located on opposite sides of the side wall 24 and respectively communicating with the air passage chamber 27. In this way, after outside air enters the atomizing chamber 412 and mixes with the aerosol, it enters the air passage chamber 27 through the through groove 28 and is then inhaled by the user through the air guide tube 12.

[0042] It should be noted that the sealing element 21 is made of sealing materials such as silicone or rubber. Its top wall 23 has a protruding bottom surface forming a sleeve part 211 that extends into the mounting position 26. The lower end of the air guide tube 12 is inserted into the sleeve part 211. The sleeve part 211 is used to achieve a sealed connection between the outer side of the air guide tube 12 and the inner side of the mounting position 26, so as to prevent the atomized liquid in the liquid storage chamber 13 from leaking into the air passage chamber 27. Of course, the sleeve part 211 can also be a separate sealing ring body that is separate from the sealing element 21.

[0043] In one embodiment, the heating element 32 is a sheet-like body, including two fixing parts 321 and an atomizing part 322 connected in series between the two fixing parts 321. The top ends of the two electrodes 42 respectively abut against the two fixing parts 321, thereby realizing the electrical connection between the two electrodes 42 and the heating element 32.

[0044] In order to improve the installation strength of the heating element 32 and prevent the heating element 32 from displacing due to the vibration of the atomizer and causing it to separate from the electrode 42, a positioning hole adapted to the diameter of the top end of the electrode 42 can be opened on the fixing part 321. The top end of the electrode 42 extends into the positioning hole, so that the electrode 42 is electrically connected to the fixing part 321, while preventing the heating element 32 from separating from the electrode 42 due to vibration, thus ensuring the reliability of the atomizer.

[0045] Because the embodiment of the present invention provides a connecting groove 25 between the two liquid inlet channels 22 of the support 20, allowing the atomized liquid to be quickly conducted to the central area of ​​the oil guide body 31, the atomizing part 322 of the heating element 32 between the two fixing parts 321 in this embodiment of the present invention can adopt an existing structure with relatively uniform heating across the entire plane. For example, the atomizing part 322 can adopt a grid-like, striped, S-shaped, zigzag, wavy, sawtooth, spiral, circular, or rectangular shape. In this embodiment, the atomizing part 322 adopts an S-shape and has multiple fixing strips 323 extending to both sides. The ends of the fixing strips 323 away from the atomizing part 322 can be bent and clamped to the top of the base 41, thereby improving the fixing strength of the heating element 32. At the same time, the fixing strips 322 can also play a partial heat conduction role, so that the heat generated by the atomizing part 322 is more evenly distributed. In this embodiment, the resistance value of the atomizing part 322 of the heating element 32 is greater than the resistance value of the fixing part 321.

[0046] In one embodiment, the heating element 30 further includes a support 33 stacked on top of the base 41, with the heating element 32 clamped and positioned between the support 33 and the oil guide 31. The support 33 has a clearance hole 331 corresponding to the atomizing part 322, which is connected to the atomizing chamber 412 at the top of the base 41. When the atomizing part 322 of the heating element 32 is heated, the aerosol generated enters the atomizing chamber 412 through the clearance hole 331. External air enters the atomizing chamber 412 through the air intake channel 414 and mixes with the aerosol. Then, it passes through the through groove 28, the air passage 27, and the air guide tube 12 in sequence, and is finally output from the air intake hole for the user to inhale. In this embodiment, the end of the fixing strip 323 away from the atomizing part 322 can be bent and clamped to the outside of the support 33, which can effectively prevent the heating element 32 from deforming during use.

[0047] Preferably, the support 33 can be a rigid sheet made of insulating material such as a dense ceramic part or a silicone part, or it can be a metal part with a non-conductive outer surface or a conductive part with an insulating layer on the top surface. For example, a sheet-like support 33 can be formed by coating the top or both sides of a metal sheet such as stainless steel to isolate the metal sheet from the heating element 32.

[0048] In this embodiment, the support body 33 supports the heating element 32. The two fixing parts 321 at both ends of the heating element 32 are respectively supported on the top surfaces of the two ends of the support body 33. The two ends of the support body 33 are respectively provided with mounting holes 332, and the two mounting holes 332 on the support body 33 correspond one-to-one with the two mounting channels 411 on the base 41. The top ends of the two electrodes 42 pass through the two mounting holes 332 and abut against the two fixing parts 321 to achieve electrical connection. It should be noted that the support body 33 may not have two mounting holes 332. In this case, the clearance hole 331 on the support body 33 covers the two mounting channels 411, that is, the top ends of the two electrodes 42 extend from the mounting channels 411 and pass through the clearance hole 331 to abut against the two fixing parts 321.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0050] The above is a description of the technical solution provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
