Description

Technical Field

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

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). The applicant has proposed an electronic atomizing device with an upper atomizing structure in patent CN221449912U, in which the atomizing surface of the atomizing component is arranged facing the outlet for the fastest possible aerosol output.

[0246] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figures 1 to 5 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply unit 200 that supplies power to the atomizer 100. Figures 1 to 5 In the illustrated embodiment, the atomizer 100 and power supply unit 200 of the electronic atomizing device are detachable from each other; electronic atomizing devices with such detachable atomizer 100 and power supply unit 200 are, for example, so-called "refillable" electronic atomizing devices. Alternatively, in some further variations, the atomizer 100 and power supply unit 200 of the electronic atomizing device are securely enclosed and fixed by a housing component of the electronic atomizing device, thereby preventing the atomizer 100 and power supply unit 200 from being detachable from each other from within the housing component. Electronic atomizing devices with such non-detachable atomizer 100 and power supply unit 200 are, for example, so-called "integrated or disposable" electronic atomizing devices.

[0247] In an alternative embodiment, for example Figures 1 to 5 As shown, the power supply unit 200 includes:

[0248] The first end 210 and the second end 220 are opposite to each other in the longitudinal direction;

When the atomizer 100 is received within the receiving cavity 250, the second electrical contact 162 of the atomizer 100 abuts against or contacts the first electrical contact 262 to form a conductive connection, thereby establishing a conductive connection between the atomizer 100 and the power supply unit 200.

[0282] In one embodiment, the first electrical contact 262 is at least partially located between the receiving cavity 250 and the second side 240. Alternatively, the first electrical contact 262 is at least partially located within the electronic cavity.

The outer shell is generally a flat, hollow cylinder containing necessary functional components for storing and atomizing the liquid matrix. In an embodiment, the outer shell includes a first housing 10 and a second housing 20 arranged longitudinally in sequence. A nozzle 11 is disposed on the first housing 10, proximal to and defining a proximal end 110; the second housing 20 proximal to and defines a distal end 120.

[0341] The liquid retaining element 40 is arranged in an annular shape around the support portion 61 of the bracket 60. In an embodiment, the liquid retaining element 40 may be made of flexible fibers such as flexible cotton fibers, nonwoven fabrics, or sponges.

[0342] In this embodiment, the liquid retaining element 40 is located between the support portion 61 and the second housing 20. The liquid retaining element 40 surrounds and covers the liquid guiding window 611 on the support portion 61; the liquid retaining element 40 is used to adsorb and retain the liquid matrix through capillary action when the liquid matrix is ​​filled into the liquid storage cavity 21, so as to prevent the positive pressure in the liquid storage cavity 21 from driving a large amount of liquid matrix to leak into the porous element 52 through the liquid guiding window 611 during the liquid filling process.

[0343] After the liquid is injected into the storage chamber 21 during production, the porous element 52 can draw the liquid matrix from the liquid holding element 40 faster than the first capillary element 32.

[0344] according to Figures 1 to 10 , Figure 13 and Figure 14 As shown, the atomizer 100 also includes:

[0345] The base 70 is configured as an annular shape with a receiving hole 72. After assembly, the connecting portion 62 of the bracket 60 is inserted into the base 70 and mechanically connected and secured to the base 70.

[0346] In the embodiments, the base 70 may be made of rigid materials such as polymer plastics and ceramics, or flexible materials such as silicone.

[0347] In one embodiment, the base 70 is provided with a plurality of spaced contact holes 71 facing the second side 140. Each of the second electrical contacts 162 extends from the second side 140 into each of the contact holes 71.

[0348] In this embodiment, a plurality of spaced-apart lead grooves 74 are also arranged on the base 70. The lead grooves 74 are at least partially formed or located on the surface of the base 70 facing the proximal end 110. After assembly, the first conductive lead 541, the second conductive lead 542, and the third conductive lead 543 extend from the connection portion 62 of the bracket 60 to the outside of the base 70, and respectively bend through the lead grooves 74 into the contact holes 71, so as to respectively contact or abut against the second electrical contact 162 for conductive connection.

[0349] In one embodiment, conductive leads, namely the first conductive lead 541, the second conductive lead 542, and the third conductive lead 543, extend from the end of the tubular element 51 toward the proximal end 110 to the outside of the tubular element 51, and are then connected to the second electrical contact 162. Also in another embodiment, the first conductive lead 541, the second conductive lead 542, and the third conductive lead 543 extend from the end of the first capillary element 32 toward the proximal end 110 to the outside of the first capillary element 32.

[0350] according to Figures 1 to 12 As shown, at least one positioning groove 73 is arranged on the inner surface of the receiving hole 72 of the base 70; a longitudinally extending positioning protrusion 66 may be arranged on the outer surface of the connecting portion 62 of the bracket 60. During assembly, the positioning protrusion 66 of the connecting portion 62 of the bracket 60 extends into the positioning groove 73 of the receiving hole 72 to provide positioning during their assembly. After assembly, the positioning protrusion 66 on the connecting portion 62 of the bracket 60 extends into the positioning groove 73 of the receiving hole 72 to prevent relative rotation between the base 70 and the connecting portion 62 of the bracket 60.

[0351] according to Figures 1 to 12 As shown, a retaining wall 12 extending toward the distal end 120 is arranged within the first housing 10; after assembly, the base 70 is mounted and positioned between the retaining wall 12 and the second side 140. The retaining wall 12 provides limiting and retention of the base 70 from the outside within the first housing 10.

[0352] In some embodiments, the bracket 60 is further provided with a plurality of buckles 65 arranged circumferentially around the connecting portion 62 at intervals; during assembly, the buckles 65 are used to extend into the slots on the first housing 10, thereby fastening the bracket 60 and the first housing 10 together.

[0353] In one embodiment, an air cavity 64 is further defined on the bracket 60 surrounding the connecting portion 62. In another embodiment, the air cavity 64 is at least partially formed or defined between the snap 65 and the connecting portion 62. After assembly, the air cavity 64 is longitudinally located between the base 70 and the bracket 60. Also after assembly, the air cavity 64 is located between the connecting portion 62 of the bracket 60 and the first housing 10.

[0354] according to Figures 1 to 12 As shown, an air groove 612 is also arranged on the inner surface of the support portion 61. In this embodiment, the air groove 612 communicates with the air cavity 64 through a communication port 661 arranged on the bracket 60. When the first segment 321 of the first capillary element 32 is inserted into the support portion 61 of the bracket 60, the air groove 612 forms or defines an air channel 34 between the first segment 321 of the first capillary element 32 and the support portion 61 of the bracket 60.

[0355] according to Figures 1 to 12 As shown, an air hole 323 is also arranged on the first section 321 of the first capillary element 32. The air hole 323 penetrates radially through the first section 321 of the first capillary element 32.

[0356] In this embodiment, the air hole 323 is closer to the distal end 120 than the atomizing assembly 50 / porous element 52. The distance between the air hole 323 and the porous element 52 is greater than 1 mm. Furthermore, the air hole 323 is located between the porous element 52 and the second capillary element 31.

[0357] In some embodiments, the diameter of the air hole 323 may be between 1.0 and 2.0 mm.

[0358] according to Figures 1 to 12 As shown, the atomizer 100 also includes:

[0359] The second air inlet 131 is arranged on the first side 130. When the atomizer 100 is received in the receiving cavity 250 of the power supply body 200, the second air inlet 131 of the atomizer 100 is aligned and connected with the first air inlet 231 of the power supply body 200.

[0360] according to Figures 1 to 12 As indicated by the middle arrow R2, the atomizer 100 also includes:

[0361] An airflow channel defines the airflow path from the second air inlet 131 through the atomizing component 50 / porous element 52 to the air outlet 111, for the purpose of outputting aerosol to the air outlet 111.

[0362] In this embodiment, the airflow channel is defined by multiple components. More specifically according to Figure 10 As shown by the middle arrow R2, the complete path of the airflow channel includes:

[0363] Air cavity 64 on bracket 60;

[0364] Air passage 34 defined by air slot 612;

[0365] Air vent 323;

[0366] The hollow cylindrical porous element 52;

[0367] Part of the tubular element 51 is hollow;

[0368] The connecting portion 62 of the bracket 60 is hollow;

[0369] The nozzle 11 is hollow.

[0370] As shown by arrow R2, the flow path within the airflow channel of the atomizer 100 during user inhalation is as follows: the air entering from the second air inlet 131 passes through the air chamber 64 in sequence and then flows from the air channel 34 defined by the air groove 612 toward the distal end 120 to the air hole 323. After entering the first capillary element 32, it carries the aerosol generated in the porous element 52 and passes through the tubular element 51, the connecting part 62 of the support 60 and the mouthpiece 11 in the direction toward the proximal end 110, and is output to the air outlet 111 for user inhalation.

[0371] In one embodiment, a portion of the airflow channel extends toward the distal end 120 between the first segment 321 of the first capillary element 32 and the support portion 61 of the bracket 60.

[0372] In one embodiment, a portion of the airflow channel flows over the outer surface of the first section 321 of the first capillary element 32. When the user draws air, the airflow channel generates a negative pressure outside the first section 321 of the first capillary element 32, which promotes the wetting and transfer of the liquid matrix from the second section 322 to the first section 321.

[0373] In one embodiment, the airflow channel avoids the liquid storage chamber 21 in the longitudinal direction. In another embodiment, the airflow channel avoids the second capillary element 31 in the longitudinal direction.

[0374] according to Figures 1 to 12 As shown, a porous absorbent element 80 is arranged between the base 70 and the first housing 10 to adsorb condensate in the airflow flowing towards the outlet 111. The porous absorbent element 80 may be made of a flexible fibrous material, such as fiber cotton. In some embodiments, the connecting portion 62 of the base 70 / support 60 has a gap after being longitudinally assembled with the first housing 10, so that the porous absorbent element 80 surrounds or encloses the gap, thereby absorbing condensate in the airflow. Alternatively, in some other embodiments, the base 70 / connecting portion 62 has a notch on its end or surface facing the proximal end 110, and the porous absorbent element 80 surrounds or encloses the notch, thereby absorbing condensate in the airflow.

[0375] according to Figures 1 to 12 As shown, the atomizer 100 also includes:

[0376] The ventilation channel 613 provides air communication between the airflow channel and the liquid storage chamber 21, thereby balancing the pressure between the liquid storage chamber 21 and the outside. Specifically, when the negative pressure inside the liquid storage chamber 21 gradually increases due to the consumption of the liquid matrix, air can enter the liquid storage chamber 21 through the ventilation channel 613 to alleviate and balance the negative pressure in the liquid storage chamber 21, such as... Figures 10 to 12 As indicated by the middle arrow R3.

[0377] In one embodiment, the ventilation channel 613 includes a slit or groove on the inner surface of the support portion 61 of the bracket 60. In another embodiment, the width and / or depth of the slit in the ventilation channel 613 may be between 0.2 and 2.0 mm. More specifically according to... Figures 1 to 12 As shown, the support portion 61 of the bracket 60 has an annular clamping structure 615 at the end near the distal end 120; the clamping structure 615 surrounds and clamps the first capillary element 32 from the outside to at least partially stably hold the first capillary element 32. Furthermore, an air exchange channel 613 is formed on the inner surface of the clamping structure 615.

[0378] In one embodiment, the ventilation channel 613 is formed between the support portion 61 of the bracket 60 and the first capillary element 32.

[0379] In this embodiment, the width or cross-sectional area of ​​the air trough 612 is greater than the width or cross-sectional area of ​​the ventilation channel 613. In this embodiment, the ventilation channel 613 is located between the air hole 323 and the liquid storage chamber 21.

[0380] according to Figures 1 to 12 As shown, the atomizer 100 also includes:

[0381] A first sensing port 143 is disposed on the second side 140. In an embodiment, the sensing port 143 is connected to the air cavity 64, and thus the first sensing port 143 is connected to the airflow channel of the atomizer 100.

[0382] according to Figure 13 and Figure 14 As shown, the power supply unit 200 also includes:

[0383] An airflow sensor 273, such as a microphone sensor or a MEMS sensor, is used to sense changes in airflow through the atomizer 100 during user inhalation. The airflow sensor 273 is securely soldered or mounted on the main circuit board 272.

[0384] according to Figure 13 and Figure 14 As shown, the power supply unit 200 also includes:

[0385] The second sensing port 274 is disposed on the inner surface of the receiving cavity 250 near the second side 240. When the atomizer 100 is received in the receiving cavity 250 of the power supply body 200, the first sensing port 143 of the atomizer 100 and the second sensing port 274 of the power supply body 200 are aligned and connected, thereby defining the sensing connection channel between the airflow sensor 273 and the air cavity 64 of the atomizer 100, so that the airflow sensor 273 can sense the change in airflow flowing through the atomizer 100 and thus determine the user's inhalation action.

[0386] Figure 15 A schematic diagram of some components of an atomizer 100 according to another embodiment is shown. In this embodiment, at least one liquid guiding slit 611a is arranged on the support portion 61a of the bracket 60a of the atomizer 100; in this embodiment, the liquid guiding slit 611a has a width of approximately 0.5 to 5 mm. After assembly, a first segment 321 of the first capillary element 32 extends into the support portion 61a; and the outer surface of the first segment 321 of the first capillary element 32 abuts against the inner surface of the support portion 61a and covers the liquid guiding slit 611a.

[0387] In the manufacturing process of the atomizer 100, when the atomizer 100 is in an inverted or flat position and the injection plug 142 is removed to fill the liquid matrix into the reservoir 21, the liquid guiding slit 611a can limit the speed or rate at which the liquid matrix flows through the liquid guiding slit 611a to the porous element 52. This prevents the positive pressure in the reservoir 21 from driving a large amount of liquid matrix to leak into the porous element 52 through the liquid guiding slit 611a during the injection process. In this embodiment, the width of the liquid guiding slit 611a is smaller than the width of the liquid guiding window 611. Therefore, during use, the smaller width of the liquid guiding slit 611a itself can prevent seepage during the injection process, which is beneficial for reducing the use of components in the liquid holding element 40 and lowering product costs.

In an embodiment, the inner shell 12b may be cylindrical. Furthermore, the end of the inner shell 12b facing the distal end 220b is connected to a support element 280b, thereby closing the end of the inner shell 12b facing the distal end 220b by the support element 280b.

In an embodiment, both the cell slot 281b and the cell 271b have a non-circular cross-sectional shape to prevent the cell 271b from rotating within the cell slot 281b.

[0410] according to Figures 16 to 25As shown, the porous element 52b is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the porous element 52b is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the electronic atomizing device.

The outer surface of the porous element 52b is in liquid communication with the first segment 321b of the first capillary element 32b, thereby the outer surface of the porous element 52b is used to absorb the liquid matrix, such as... Figure 21 As indicated by the middle arrow R1.

[0411] In some embodiments, the inner surface of the porous element 52b in the radial direction is configured as an atomizing surface, which is combined / adhered / abutted against the first heating element 531b and / or the second heating element 532b; subsequently, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the first heating element 531b and / or the second heating element 532b to generate an aerosol and release it.

Then, the first conductive lead 541b, the second conductive lead 542b, and the third conductive lead 543b are connected to the circuit board 272b. Thus, in use, the first conductive lead 541b, the second conductive lead 542b, and the third conductive lead 543b can be connected in parallel to guide current through the first heating element 531b and the second heating element 532b, thereby enabling the first heating element 531b and the second heating element 532b to operate simultaneously in parallel.

[0415] according to Figures 16 to 25 As shown, the electronic atomizing device also includes:

[0416] A tubular element 51b is arranged extending longitudinally along the electronic atomizing device. The tubular element 51b may be made of rigid ceramic, metal, or alloy, for example, it may be made of stainless steel; the tubular element 51b is used to surround or hold the porous element 52b. The porous element 52b is housed and held within the tubular element 51b.

[0423] After assembly, the atomizing assembly / porous element 52b is housed and held within a first section 321b of the first capillary element 32b. In some embodiments, the first capillary element 32b is configured to transfer a liquid matrix from the reservoir 21b toward the proximal end 210b to the atomizing assembly / porous element 52b along the longitudinal direction of the electronic atomizing device.

Alternatively, the porous element 52b is located within the first segment 321b of the first capillary element 32b and does not extend beyond or protrude from the first capillary element 32b. In this embodiment, the distance between the end of the first capillary element 32b towards the proximal end 210b and the porous element 52b is greater than or equal to 2 mm. Therefore, during suction, gravity accelerates the liquid supply from the first segment 321b to the porous element 52b, which helps to increase the replenishment of the liquid matrix in the porous element 52b during suction.

[0456] In one embodiment, the support 60b is annular; the first capillary element 32b is inserted into the support 60b with its proximal end 210b facing towards it, and is thus supported by the support 60b.

More specifically, a portion of the airflow channel flows over the outer surface of the first segment 321b of the first capillary element 32b in a direction from the proximal end 210b to the distal end 220b.

[0484] In one embodiment, the airflow channel extends from outside the first section 321b of the first capillary element 32b to inside the first section 321b via the air hole 323b.
