Description

Technical Field

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

[0002] Existing electronic atomizers using a planar heating element structure also have a flat wicking body. The planar heating element is located on the bottom surface of the wicking body. The aerosol produced after the heating element atomizes the aerosol must pass around both sides of the wicking body before merging and exiting through the air tube. This results in a long airflow path for the aerosol before it enters the air tube, which can lead to excessive condensation in the path. This condensation can easily accumulate and cause the condensate to be inhaled along with the aerosol during vaping, thus affecting the user's vaping experience. Summary of the Invention

[0046] This invention provides an electronic atomization device, including an atomizer and a battery rod (not shown). The atomizer and battery rod can be an integrated structure or a separate structure. The battery rod has a power supply and a control circuit inside. The control circuit is used to control the power supply to provide power to the atomizer.

[0047] The atomizer provided by the present invention will be described in detail below with reference to the accompanying drawings:

[0048] Please see Figure 1-4 The atomizer provided in this embodiment of the invention includes an oil cup 10 and an atomizing component installed in the oil cup 10.

[0049] The bottom of the oil cup 10 is open, and the top has an air inlet 11 for the user to inhale. An air guide tube 12 is formed on the inner wall of the top of the oil cup 10 at the edge of the air inlet 11, extending into the interior of the oil cup 10. 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.

[0050] The atomizing assembly includes a bottom assembly 40, a top assembly 20 installed on the top of the bottom assembly 40, and a heating assembly 30 clamped and positioned between the bottom assembly 40 and the top assembly 20. The atomizing assembly also has an airflow channel 50 that runs vertically through the top assembly 20 and the heating assembly 30 and is connected to the air duct 12. An atomizing chamber 411 is formed between the bottom assembly 40 and the heating assembly 30 and is connected to the air intake channel 412 provided at the bottom of the bottom assembly 40.

[0051] The top component 20 is installed inside the oil cup 10 and sealed to the inner wall of the oil cup 10. The top component 20 is provided with an inlet channel 221 for supplying the atomized liquid in the liquid storage chamber 13 to the heating component 30. When the user inhales through the inhalation port 11, the heating component 30 is manually or automatically controlled to heat and atomize the atomized liquid absorbed from the inlet channel 221, thereby generating an aerosol that can be inhaled by the user in the atomization chamber 411. At the same time, external air enters the atomization chamber 411 from the air intake channel 412 and mixes with the generated aerosol. After passing through the airflow channel 50 and the air guide tube 12, it is finally inhaled by the user through the inhalation port 11.

[0052] Combination Figure 5 As shown, the heating assembly 30 includes an oil guide body 31 and a heating element 32 stacked together. The oil guide body 31 is connected to the liquid inlet channel 221 and has a first airflow hole 53 forming part of the airflow channel 50. The heating element 32 is located on the side of the oil guide body 31 away from the top assembly 20 and bypasses the first airflow hole 53. The oil guide body 31 is a sheet-like body made of oil-absorbing cotton or porous ceramic body. Therefore, 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 guide 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.

[0053] The heating element 32 is sandwiched between the oil guide body 31 and the bottom component 40. With this structure, the aerosol generated in the atomization chamber 411 when the heating element 32 heats and atomizes can be directly discharged through the first airflow hole 53. The discharge process has no corners and the discharge path is short, which can reduce the generation of condensate and avoid the phenomenon of users sucking up condensate. In addition, this structure has a fast oil supply speed and a large atomization area, thus giving users a better suction experience.

[0054] In this embodiment, the heating element 32 is a sheet-like body, including two conductive parts 321 and several atomizing parts 322. The two conductive parts 321 are located at opposite ends of the oil guide body 31 and are electrically connected to the two electrodes 42 of the bottom component 40, so that the heating element 32 is powered by the power supply inside the battery rod.

[0055] For example, in this embodiment, the heating element 32 may further include a connecting part 323. The connecting part 323 is located on the side of the oil guide body 31 facing the atomizing chamber 411 and bypasses the first airflow hole 53. There are two atomizing parts 322, located on the side of the oil guide body 31 facing the atomizing chamber 411 and respectively located on both sides of the first airflow hole 53. The two atomizing parts 322 are respectively connected to both sides of the connecting part 323. The two conductive parts 321 are respectively connected to the side of the two atomizing parts 322 away from the connecting part.

[0056] The shape and size of the atomizing part 322 can be set according to actual needs. For example, the atomizing part 322 can be S-shaped, zigzag-shaped or rectangular, and the resistance value of the atomizing part 322 is greater than the resistance value of the conductive part 321. Preferably, the resistance value of the atomizing part 322 is also greater than the resistance value of the connecting part 323.

[0057] It should be understood that the heating element 32 and the oil guide 31 in this embodiment are separate structures, which are fixed to each other by clamping the top component 20 and the bottom component 40. The heating element 32 may also be bent to form a retaining part that is embedded in the oil guide 31 or clamped on the side wall of the oil guide 31. Of course, in other embodiments, the heating element 32 and the oil guide 31 may also be integrally sintered, or the heating element 32 may be formed on the oil guide 31 by printing, coating, etching or other methods.

[0058] As an alternative embodiment of the heating element 32, such as Figure 6 As shown, the heating element 32 includes two conductive parts 321, two atomizing parts 322, and an annular connecting part 324. The annular connecting part 324 is located on the side of the oil guide body 31 facing the atomizing cavity 411 and is coaxially arranged with the first airflow hole 53. The two atomizing parts 322 are symmetrically connected to both sides of the annular connecting part 324 on the side of the oil guide body 31 facing the atomizing cavity 411. The two conductive parts 321 are respectively connected to the side of the two atomizing parts 322 away from the connecting part.

[0059] In one embodiment, the top component 20 is also provided with a ventilation channel 60. The two ends of the ventilation channel 60 are connected to the airflow channel 50 and the liquid inlet channel 221, respectively. When the user draws in air, the atomized 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. After the external gas mixes with the aerosol, some of the airflow enters the liquid storage chamber 13 through the ventilation channel 60 when passing through the airflow channel 50, thereby achieving ventilation to balance the internal and external air pressure of the liquid storage chamber 13.

[0060] In this embodiment, by having the airflow channel 50 pass through the heating component 30, the path of the ventilation channel 60 is shortened, the number of components involved in the ventilation path is reduced, and the adverse problems caused by the manufacturing tolerance / assembly cumulative tolerance of components, such as airway blockage and excessively large airway, are effectively reduced, thereby improving ventilation reliability and enhancing the user's suction experience.

[0061] In one embodiment, the top assembly 20 includes a seal 21 and a bracket 22. The seal 21 is installed inside the oil cup 10 and is sealed to the inner wall of the oil cup 10. Specifically, the seal 21 is made of elastic sealing materials such as silicone or rubber. The outer wall of the seal 21 has a plurality of annular protrusions 212 formed along its axial direction. The plurality of protrusions 212 elastically abut against the inner wall of the opening end of the oil cup 10, thereby achieving a sealed connection between the seal 21 and the inner wall of the oil cup 10 to form a sealed liquid storage cavity 13.

[0062] The top end of the bracket 22 is installed inside the seal 21, and the bottom end is fitted onto the top end of the bottom assembly 40. The bracket 22 is provided with a second airflow hole 52 and a liquid inlet channel 221, and the seal 21 is provided with a third airflow hole 51 and a liquid inlet 211. The third airflow hole 51 communicates with the second airflow hole 52 and is sleeved and connected to the lower end of the air guide tube 12. The liquid inlet 211 communicates with the interior of the oil cup 10 and the liquid inlet channel 221. Through the liquid inlet channel 221 and the liquid inlet 211, the heating element 30 is connected to the liquid storage chamber 13 of the oil cup 10, so that the atomized liquid in the liquid storage chamber 13 can be guided to the heating element 30 through the liquid inlet channel 221.

[0063] In one embodiment, combined Figure 7 As shown, the bracket 22 includes a top wall 222 and a first side wall 223 extending downward along the periphery of the top wall 222. The first side wall 223 is fitted onto the upper end of the bottom component 40. The second airflow hole 52 and the liquid inlet channel 221 are both formed in the top wall 222. The top surface of the oil guide body abuts against the bottom surface of the top wall 222, and the air exchange channel 60 is formed between the oil guide body and the top wall 222. In practical applications, the first side wall 223 is fixed to the bottom component 40 by screwing, plugging, or snap-fit ​​connection, thereby clamping and fixing the heating component 30 between the top wall 222 and the bottom component 40, making the assembly of the atomizing component more convenient and reliable. The oil guide body is a porous ceramic body or oil-absorbing cotton, and its shape is roughly adapted to the top wall 222. The periphery of the oil guide body abuts against the inner side of the first side wall 223. In this embodiment, the heating component 30 is firmly fixed to the upper end of the bottom component 40 by the bracket 22, and the top wall 222 and the oil guide body are tightly fitted to cover the lower end of the liquid inlet channel 221 to avoid oil leakage.

[0064] Specifically, in this embodiment, the ventilation channel 60 is formed between the oil guide body and the top wall 222. Specifically, the bottom surface of the top wall 222 has a ventilation groove 224 communicating with the second airflow hole 52 and the liquid inlet channel 221. The ventilation groove 224, in cooperation with the oil guide body, forms the ventilation channel 60. This not only simplifies the structure of the support 22, but also ensures that the ventilation channel 60 is short and straight from the airflow channel 50. Of course, in other embodiments, the ventilation channel 60 can also be located between the top wall 222 and the sealing member 21, that is, the ventilation groove 224 can be opened on the top surface of the top wall 222, forming the ventilation channel 60 in cooperation with the sealing member 21.

[0065] It should be noted that the airflow channel 50 is located in the middle of the top component 20 and the heating component 30, and there are two liquid inlet channels 221, which are symmetrically arranged relative to the airflow channel 50. That is, the two atomizing parts of the heating element correspond to the two liquid inlet channels 221 respectively. This structure ensures that the oil guide can smoothly guide the oil while also ensuring that the path of the ventilation channel 60 is short. The cross-sectional shape of the ventilation groove 224 can be semi-circular, triangular, or polygonal. In practical applications, the number of ventilation grooves 224 can be selected according to their cross-sectional size. In this embodiment, two ventilation grooves 224 are provided between each liquid inlet channel 221 and the airflow channel 50.

[0066] In one embodiment, the bottom component 40 includes a base 41 mounted to the bottom of the oil cup 10 and two electrodes 42 inserted into the base 41 from the direction of the top component 20. The base 41 is inserted and fixed into the open end of the oil cup 10 by a snap-fit ​​connection, so that the heating component 30 is clamped and positioned between the bracket 22 and the base 41, and an atomizing chamber 411 communicating with the airflow channel 50 is formed between the heating component 30 and the base 41. The heating element of the heating component 30 is located on the side of the oil guide body facing the atomizing chamber 411, and the top ends of the two electrodes 42 are electrically connected to the two ends of the heating element, respectively.

[0067] Furthermore, combined Figure 8As shown, the bottom assembly 40 also includes a support body 43 installed on the top of the base 41. The support body 43 includes a partition 431 that extends into the atomizing chamber 411 and divides the atomizing chamber 411 into an upper chamber 411A and a lower chamber 411B. A connecting hole 434 is provided at the periphery of the partition 431 to connect the upper chamber 411A and the lower chamber 411B. Two electrodes 42 pass through the two connecting holes 434 respectively and abut against the bottom of both ends of the heating element assembly. The top of the partition 431 is recessed downward to form a collection groove 432. The axial projection of the collection groove 432 on the atomizer covers the cross-section of the airflow channel 50. In this embodiment, the collection tank 432 is used to collect leaked atomizing liquid and condensate in the recirculated gas. Specifically, the airflow channel 50 and the air intake channel 412 are located above and below the partition 431, respectively, and the air intake channel 412 is coaxially arranged with the airflow channel 50. The partition 431 prevents condensate or atomizing liquid from entering the atomizing chamber 411 and flowing out through the air intake channel 412. Preferably, the bottom of the collection tank 432 has several first grooves 433. When the recirculated gas comes into contact with the partition 431, the first grooves 433 in the collection tank 432 use capillary suction to adsorb the condensate in the recirculated gas.

[0068] Preferably, there are two connecting holes 434, which are respectively opened at both ends of the partition 431. That is, the two connecting holes 434 correspond to the two electrode holes of the base 41, and the two electrodes 42 pass through the two connecting holes 434 and abut against the heating element to achieve electrical connection. With this structure, in this embodiment, when assembling the atomizing component, the support 43, the heating component 30 and the top component 20 can be stacked and installed on the top of the base 41 in sequence to form a fixed whole. Then the whole atomizing component is assembled into the lower opening of the oil cup 10, which makes the assembly more convenient and faster and improves production efficiency.

[0069] It should be noted that the diameter of the connecting hole 434 is larger than the diameter of the electrode 42. Even if the electrode 42 is inserted into the connecting hole 434, it will not affect the connection between the upper cavity 411A and the lower cavity 411B. That is, after the external air enters the lower cavity 411B from the air intake channel 412, it can enter the upper cavity 411A through the connecting hole 434 without hindrance, thereby mixing with the aerosol and finally being inhaled by the user.

[0070] In one embodiment, combined Figure 9 and Figure 10As shown, the base 41 includes a bottom wall 413 and a second side wall 414 extending upward along the periphery of the bottom wall 413. The bottom wall 413, the second side wall 414, and the heating element 30 together form an atomizing chamber 411, and an air intake channel 412 is opened in the bottom wall 413. Specifically, the first side wall 223 of the bracket 22 is sleeved and fixed to the upper end of the second side wall 414 by a snap-fit ​​connection, so that the top component 20, the heating element 30, and the bottom component 40 are fixed to each other; while the outer periphery of the second side wall 414 has an annular groove, in which a sealing ring is embedded. The base 41 is fixed to the opening end of the oil cup 10 by a snap-fit ​​connection, and the sealing ring is used to achieve a sealed connection with the opening end of the oil cup 10.

[0071] Furthermore, the bottom wall 413 extends protruding towards the atomizing chamber 411 with an air inlet pipe 415 forming an air inlet channel 412, and the top surface of the bottom wall 413 has multiple protrusions 416 for adsorbing condensate. In this way, after the return gas is blocked and diverted by the partition 431, it enters the lower cavity 411B through the two connecting holes 434 respectively. Then, the multiple protrusions 416 on the bottom wall 413 adsorb the condensate in the return gas. At the same time, in conjunction with the protruding air inlet pipe 415, it can prevent condensate or atomized liquid from flowing out of the air inlet channel 412.

[0072] Preferably, the inner side of the second sidewall 414 protrudes towards the central axis from the position corresponding to the connecting hole 434 to form an arc surface 417, and the arc surface 417 is provided with a plurality of second grooves 418 extending axially. When the return gas enters the lower cavity 411B from the connecting hole 434, the plurality of second grooves 418 on the arc surface 417 can be used to absorb the condensate in the return gas.

[0073] 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.

[0074] 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.
