Description

Technical Field

[0002] An electronic atomizing device is a device that uses electricity to heat a liquid, causing it to atomize. The atomizing component, as the core of the electronic atomizing device, plays a crucial role, and its structural stability affects many aspects of the device. For example, whether leakage or coil burning occurs, as well as the flavor, are all determined by the quality of the atomizing component. The stability of the atomizing component is related to its own structure, assembly, and the precision of its components.

[0003] When the atomizing components of related technologies are working, gas may enter during the process of supplying the atomizing liquid to the heating element. This gas may occupy the liquid supply channel, causing insufficient liquid supply and leading to wick clogging. In addition, the size of the liquid inlet hole also affects leakage. If the liquid inlet hole is too large, leakage is likely to occur, and if the liquid inlet hole is too small, insufficient liquid supply will also occur. Summary of the Invention

[0038] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0039] like Figure 1 The diagram illustrates an embodiment of an electronic atomizing device. This device includes components for heating an atomized aerosol generating matrix. In this embodiment, the aerosol generating matrix can be a liquid aerosol generating matrix, i.e., an atomizing liquid. In some embodiments, the electronic atomizing device may include a generally columnar atomizer 100 and a power supply assembly (not shown) detachably connected to the atomizer 100. The atomizer 100 can be used to contain and heat the atomized aerosol generating matrix. The power supply assembly may include a battery for supplying power to the atomizer 100.

[0040] See also Figure 1 and Figure 2 The atomizer 100 includes a housing 10 and an atomizing component 20. The housing 10 may be a hollow structure, and the atomizing component 20 can be housed within the housing 10. The housing 10 may include a liquid storage structure to facilitate liquid supply to the atomizing component 20. A liquid storage chamber 40 for storing atomized liquid is formed within the housing 10. The atomizer 100 also includes a base 30 disposed within the housing 10. Specifically, the base 30 is detachably connected to the housing 10 and may be located at the bottom of the housing 10, defining the liquid storage chamber 40 between the base 30 and the housing 10. The atomizing component 20 can be installed on the base 30 and housed within the housing 10. The base 30 is also provided with an air inlet 301, which communicates with the outside environment and the gas of the atomizing component 20 to allow air to enter the atomizer 100 and participate in atomization. The housing 10 is provided with an air outlet 50 opposite to the air inlet 301 for discharging aerosol. In some embodiments, the atomizer 100 further includes a mouthpiece connected to the air outlet 50 for the user to inhale the aerosol. The atomizing component 20 is in communication with the liquid reservoir 40, allowing the atomized liquid to be stored in the liquid guide, reducing the likelihood of leakage. Furthermore, the modular design of the atomizing component 20 makes it simpler and more convenient to use, and easier to replace without needing to replace the liquid reservoir 40.

[0041] See also Figure 3 and Figure 4 The atomizing assembly 20 is used to heat the atomizing liquid. It includes a first mounting bracket 1 and a second mounting bracket 2, which may be tubular. The second mounting bracket 2 has a receiving space for mounting the first mounting bracket 1 and is sleeved on the outside of the first mounting bracket 1. The first mounting bracket 1 includes an air inlet end 101 and an air outlet end 102 opposite to the air inlet end 101. In some embodiments, the atomizer 100 further includes at least one first sealing member 60, which is disposed on the outer wall of the second mounting bracket 2 to achieve a seal between the atomizing assembly 20 and the liquid storage chamber 40. In some embodiments, the number of first sealing members 60 may be two, and they are respectively located on the outer walls of opposite axial ends of the second mounting bracket 2.

[0042] A heating element 3 is disposed inside the first mounting bracket 1, and a first liquid guiding component 11 is disposed outside the heating element 3. A second liquid guiding component 21 is disposed between the first mounting bracket 1 and the second mounting bracket 2. The second liquid guiding component 21 can be correspondingly disposed with the first liquid guiding component 11 and the heating element 3. The second liquid guiding component 21 is in liquid communication with the liquid storage tank 40 to form a liquid supply channel. In this way, the atomized liquid stored in the liquid storage tank 40 can be guided to the heating element 3 in sequence through the second liquid guiding component 21 and the first liquid guiding component 11. It can be understood that in this embodiment, the liquid supply channel can be formed by the liquid-conducting second liquid guiding component 21 and the first liquid guiding component 11 to achieve liquid supply to the heating element 3, so that the atomized liquid can be heated on the heating element 3.

[0043] In some embodiments, the first liquid guiding element 11 and the second liquid guiding element 21 can be made of porous materials such as cotton. In this way, the atomizing liquid can enter the heating element 3 sequentially through the first liquid guiding element 11 and the second liquid guiding element 21, and the first liquid guiding element 11 and the second liquid guiding element 21 can store the atomizing liquid to facilitate rapid supply to the heating element 3 for heating, which can effectively improve the atomization efficiency.

[0044] The second mounting bracket 2 is provided with a limiting part 4, and a ventilation channel 41 for gas to pass through is formed between the limiting part 4 and the air outlet end 102 of the first mounting bracket 1. By setting the limiting part 4 and forming the ventilation channel 41, the gas brought in during the process of supplying the atomizing liquid to the heating element 3 can be discharged through the ventilation channel 41, thereby solving the problem of insufficient liquid supply caused by gas occupying the liquid supply channel, ensuring normal liquid supply to the heating element 3, and avoiding the occurrence of wick clogging.

[0045] Combination Figure 6 The heating element 3 includes a heating part 31 and an electrode lead part 32 electrically connected to the heating part 31. The heating part 31 can be a tubular structure. The first liquid guiding member 11 is provided with an axial perforation 111. The heating part 31 can be located in the axial perforation 111 and form an air guiding channel, in which airflow can flow. When the airflow enters the air guiding channel, it simultaneously carries away the aerosol generated by atomization and discharges it from the air outlet 102 for the user to inhale.

[0046] The outer circumferential surface of the first liquid guiding element 11 forms a liquid absorption surface, which can directly contact the atomized liquid. The inner circumferential surface of the first liquid guiding element 11 forms a liquid guiding surface. The heating element 3 can be embedded or attached to the liquid guiding surface. The side of the heating element 3 connected to the first liquid guiding element 11 is the atomizing surface, so that the atomized liquid is led to the heating element 3 for heating through the liquid absorption surface and the liquid guiding surface.

[0047] In some embodiments, the first liquid guiding element 11 can cover the atomizing surface of the heating element 3, that is, the area of ​​the liquid guiding surface can be greater than or equal to the area of ​​the atomizing surface; at the same time, the area of ​​the liquid guiding surface can also be greater than the opening area of ​​the first liquid inlet hole 12, so that the atomizing liquid can be fully supplied to the atomizing surface of the heating element 3 for heating, thereby improving the atomization efficiency.

[0048] See also Figure 5 and Figure 6 In some embodiments, the first mounting bracket 1 is conductive, and the air inlet 101 has a conductive extension 5 that extends from the outer wall of the air inlet 101 in a direction away from the axis of the first mounting bracket 1. In some embodiments, the outer diameter of the air outlet 102 is smaller than the outer diameter of the air inlet 101. In some embodiments, the first mounting bracket 1 can be made of a thin metal sheet by stretching and stamping, which results in higher manufacturing efficiency and more precise dimensions.

[0049] In some embodiments, the first mounting bracket 1 is further provided with an electrode shell 6, and the heating element 3 is electrically connected to the electrode shell 6 and the first mounting bracket 1. A receiving groove 14 is formed in the first mounting bracket 1 near the air outlet 102, and the heating element 3 can be installed in the receiving groove 14; the electrode shell 6 is installed at the air inlet 101. The mounting bracket can support the heating element 3 and the electrode shell 6, and can also serve as part of the electrode.

[0050] The electrode lead section 32 includes a first electrode lead 321 and a second electrode lead 322. The first electrode lead 321 is electrically connected to the electrode shell 6; the second electrode lead 322 is electrically connected to the extension section 5. At this time, the electrode shell 6 can form a first electrode contact and the extension section 5 can form a second electrode contact. The battery can be connected to the two electrode contacts in a contact manner, thus realizing circuit connection without the need to solder it to the battery with additional leads. Moreover, the atomizing component 20 is more convenient to replace by connecting to the battery in a contact manner.

[0051] In some embodiments, the atomizing assembly 20 further includes a fixing member 7 housed at the air inlet 101. This fixing member 7 can be used to fix the second electrode lead 322 to the mounting bracket, forming a conductive path. In this case, the extension 5 of the mounting bracket can form a second electrode contact. Simultaneously, the fixing member 7 can serve as an insulator between the first electrode lead 321 and the second electrode lead 322. The fixing member 7 may be generally columnar, with a through hole 71 extending through its axially opposite surfaces. The circumferential sidewall 74 of the fixing member 7 is provided with a positioning groove 72 through which the electrode lead portion 32 passes, and the second electrode lead 322 can pass through this positioning groove 72.

[0052] Combination Figure 3 and Figure 4In some embodiments, the fixing member 7 includes a top wall 73 and a side wall 74. The fixing member 7 has a protrusion 75 extending from the top wall 73 towards the air inlet end 101, and a through hole 71 penetrates the top wall 73 and communicates with the air inlet end 101. In some embodiments, the fixing member 7 further includes a mounting groove 76 for mounting the electrode housing 6. The mounting groove 76 is formed between the side wall 74 and the protrusion 75 and is circumferentially arranged around the through hole 71. The size of the mounting groove 76 can be adapted to the size of the electrode housing 6 so that the electrode housing 6 can be installed in the mounting groove 76.

[0053] like Figure 6 As shown, in some embodiments, the first electrode lead 321 is partially housed in the mounting groove 76 and abuts against the electrode housing 6. The end of the first electrode lead 321 away from the heating part 31 passes through the through hole 71 of the fixing member 7 and forms a bent structure to be housed in the mounting groove 76, and abuts against the electrode housing 6 to form a conductive connection, thus forming a first electrode contact.

[0054] The atomizing assembly 20 also includes a columnar second seal 8 disposed within the first mounting bracket 1, which separates the first electrode lead 321 and the second electrode lead 322. In some embodiments, the second seal 8 includes a mounting hole 81 extending through its axially opposite surfaces, through which the first electrode lead 321 passes, and the second electrode lead 322 abuts against the outer wall surface of the second seal 8 away from the mounting hole 81. The second seal 8 can be used to secure the electrode lead portion 32, preventing liquid from flowing downwards along the electrode lead portion 32.

[0055] In some embodiments, the end face of the extension 5 away from the vent end 102 and the end face of the electrode housing 6 away from the vent end 102 are on the same horizontal plane, so that the first electrode contact and the second electrode contact can form good contact when they contact the battery, which facilitates operation.

[0056] During assembly, firstly, the first liquid guiding component 11 is wrapped around the heating element 3 and installed into the first mounting bracket 1. Then, the second sealing component 8 is installed, separating the first electrode lead 321 and the second electrode lead 322 of the heating element 3. The first electrode lead 321 passes through the mounting hole 81 of the second sealing component 8, and the second electrode lead 322 is fixed between the outer wall of the second sealing component 8 and the inner wall of the mounting bracket. Thus, the extension 5 on the first mounting bracket 1 forms the second electrode contact. Next, the fixing component 7 is installed to fix the second electrode lead 322, ensuring good conductivity between the second electrode lead 322 and the first mounting bracket 1. The first electrode lead 321 passes through the central hole of the fixing component 7 and bends into the groove of the fixing component 7. Then, the electrode shell 6 is installed and fixed to secure the first electrode lead 321, forming the first electrode contact. Finally, the second liquid guiding component 21 is fitted onto the outside of the first mounting bracket 1 and installed into the second mounting bracket 2.

[0057] like Figure 4 As shown, in some embodiments, the second mounting bracket 2 includes a main body segment 24 and a constricted segment 25 connected to one end of the main body segment 24. The main body segment 24 is sleeved outside the first mounting bracket 1, and the constricted segment 25 is used to limit the first mounting bracket 1. The inner diameter of the constricted segment 25 is smaller than the inner diameter of the main body segment 24, and the inner diameter of the constricted segment 25 is smaller than the outer diameter of the first mounting bracket 1. The first mounting bracket 1 is located inside the main body segment 24, and the constricted segment 25 can restrict the axial movement of the first mounting bracket 1, preventing the first mounting bracket 1 from dislodging from the receiving space of the second mounting bracket 2 when it moves axially upward during installation.

[0058] Combine Figure 7 and Figure 8 In some embodiments, the constricted section 25 includes a first end 251 connected to the main body section 24 and a second end 252 opposite to the first end 251. A limiting portion 4 is formed on the end face of the first end 251 to limit the first mounting bracket 1 and form a ventilation channel 41. In some embodiments, the limiting portion 4 may include a plurality of protrusions 42, which are spaced apart on the end face of the first end 251. In some embodiments, the plurality of protrusions 42 may be arranged at equal intervals. Understandably, a groove is formed between two adjacent protrusions 42, so a plurality of spaced protrusions 42 can form a plurality of grooves, which form a ventilation channel 41 through which gas can pass.

[0059] See also Figure 5 In some embodiments, the first mounting bracket 1 is provided with a longitudinally elongated first liquid inlet hole 12, which penetrates the inner and outer surfaces of the first mounting bracket 1 and can extend along the height direction of the first mounting bracket 1. See also... Figure 7 The second mounting bracket 2 is provided with a second liquid inlet 22 corresponding to the first liquid inlet 12. The second liquid inlet 22 can be longitudinally elongated, penetrating the inner and outer surfaces of the second mounting bracket 2, and can extend along the height direction of the second mounting bracket 2. The second liquid inlet 22 is directly connected to the atomizing liquid in the liquid storage tank 40. The atomizing liquid is first guided through the second liquid inlet 22 to the second liquid guide 21, then through the first liquid inlet 12 to the first liquid guide 11, and finally to the heating element 3. The positions of the first liquid inlet 12 and the second liquid inlet 22 can be correspondingly arranged to facilitate liquid inlet.

[0060] The diameters of the first liquid inlet 12 and the second liquid inlet 22 can be adjusted according to actual conditions. In some embodiments, the diameter of the first liquid inlet 12 can be larger than the diameter of the second liquid inlet 22. Relatively speaking, the first liquid inlet 12 is larger and the second liquid inlet 22 is smaller, so that when the atomizing liquid enters from the second liquid inlet 22, it is first evenly distributed by the second liquid guide 21 before being supplied to the first liquid guide 11. The second liquid guide 21 effectively decomposes the pressure of the atomizing liquid, reducing the liquid pressure at the first liquid guide 11, thus making leakage less likely.

[0061] Furthermore, in some embodiments, the thickness of the second liquid guide 21 can be less than the thickness of the first liquid guide 11. When the atomizing liquid is consumed by heating, the gas pressure in the storage chamber 40 decreases, and external gas enters the storage chamber 40. Since the second liquid guide 21 is thinner, the gas preferentially passes through the second liquid guide 21 and does not occupy the microporous liquid supply channel of the first liquid guide 11. Therefore, it is less likely to cause core clogging, which is beneficial to improving the stability of the structure.

[0062] See also Figure 5 In some embodiments, the first mounting bracket 1 is further provided with a first air inlet 13, which is located below the first liquid inlet 12, that is, the first air inlet 13 is closer to the air inlet end 101 than the first liquid inlet 12. See also Figure 7 The second mounting bracket 2 is also provided with a second air inlet 23, which is located below the second liquid inlet 22. That is, the second air inlet 23 is closer to the air inlet end 101 than the second liquid inlet 22, so as to facilitate control of the amount of gas entering.

[0063] In some embodiments, the second air inlet 23 is closer to the air inlet end 101 than the first air inlet 13, meaning the second air inlet 23 is lower than the first air inlet 13 in the gas flow direction. When the user inhales, the gas enters from the air inlet 301 at the bottom of the atomizing component 20, flows upward in the airflow direction, first passes through the first annular space 201 formed in the second mounting bracket 2, then enters the second annular space 202 formed between the first mounting bracket 1 and the second mounting bracket 2 through the second air inlet 23, then enters the air guide channel through the first air inlet 13, and finally exits through the air outlet 50 through the air outlet channel of the housing 10. Since the airflow direction is upward, setting the second air inlet 23 closer to the air inlet end 101 than the first air inlet 13 makes the airflow smoother. The multi-level annular space formed by the first annular space 201 and the second annular space 202 can better prevent leakage of atomizing liquid and condensate.

[0064] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
