Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and more particularly to an atomizer and an 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, there are aerosol-providing articles, such as so-called electronic atomizing devices. These devices typically contain a vaporizable liquid that is heated to vaporize, thereby producing an inhalable aerosol. In the aforementioned electronic atomizing devices, the liquid delivery element delivers the liquid matrix to the heating element junction too much or too quickly, resulting in spitting during heating.

[0162] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.
[0163] This application proposes an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 100 that stores a liquid matrix and vaporizes it to generate an aerosol, and a power supply assembly 200 that supplies power to the atomizer 100.
[0164] In an alternative implementation, for example Figure 1 As shown, the power supply assembly 200 includes a receiving cavity 270 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and a first electrical contact 230 at least partially exposed on the surface of the receiving cavity 270 for supplying power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply assembly 200.
[0165] according to Figure 1 In the preferred embodiment shown, a second electrical contact 21 is provided on the end of the atomizer 100 opposite to the power supply assembly 200 along the length direction. When at least a portion of the atomizer 100 is received in the receiving cavity 270, the second electrical contact 21 becomes conductive by contacting and abutting against the first electrical contact 230.
[0166] A seal 260 is provided within the power supply assembly 200, and the seal 260 divides at least a portion of the internal space of the power supply assembly 200 to form the receiving cavity 270. Figure 1 In the preferred embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power assembly 200, and is preferably made of a flexible material, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing into components such as the controller 220 and sensor 250 inside the power assembly 200.
[0167] exist Figure 1 In the preferred embodiment shown, the power supply assembly 200 further includes a battery cell 210 for power supply located at the other end of the receiving cavity 270 along the length direction; and a controller 220 disposed between the battery cell 210 and the receiving cavity, the controller 220 being operable to guide current between the battery cell 210 and the first electrical contact 230.
[0168] In use, the power supply assembly 200 includes a sensor 250 for sensing the suction airflow generated when the atomizer 100 is inhaled, and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250.
[0169] Further in Figure 1 In the preferred embodiment shown, the power supply assembly 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210.
[0170] Figures 2 to 5 The embodiments are shown Figure 1 A schematic diagram of one embodiment of the atomizer 100 includes:
[0171] Main housing 10; according to Figures 2 to 3 As shown, the main housing 10 is generally flat and cylindrical, and its interior is hollow to store and atomize the necessary functional components of the liquid matrix. The main housing 10 has a proximal end 110 and a distal end 120 that are opposite each other along the length direction. The proximal end 110 is configured as the end for the user to inhale the aerosol, and a mouthpiece A for the user to inhale is provided at the proximal end 110. The distal end 120 is the end that is connected to the power supply assembly 200, and the distal end 120 of the main housing 10 is open, on which a removable end cap 20 is installed. The open structure is used to install the necessary functional components inside the main housing 10.
[0172] Further in Figures 2 to 3In the specific implementation shown, the second electrical contact 21 extends from the surface of the end cap 20 into the interior of the atomizer 100, thus at least partially exposed outside the atomizer 100, allowing it to contact the first electrical contact 230 and thus form an electrical connection. Simultaneously, the end cap 20 is also provided with a first air inlet 22 for allowing external air to enter the atomizer 100 during inhalation. Further details can be found in the following sections. Figure 3 As shown, after assembly, the second electrical contact 21 is flush with the surface of the end cap 20.
[0173] See further Figures 3 to 5 As shown, the main housing 10 has a liquid storage chamber 12 for storing a liquid matrix, and an atomizing assembly for drawing the liquid matrix from the liquid storage chamber 12 and heating and atomizing the liquid matrix. Among these, in... Figure 5 In the cross-sectional structural schematic diagram shown, the main housing 10 is provided with a flue gas transmission pipe 11 arranged along the axial direction. The space between the outer wall of the flue gas transmission pipe 11 and the inner wall of the main housing 10 forms a liquid storage chamber 12 for storing liquid matrix. The first end of the flue gas transmission pipe 11 relative to the proximal end 110 is connected to the mouthpiece A, thereby transmitting the generated aerosol to the mouthpiece A for inhalation.
[0174] As shown in the figure, the flue gas transmission pipe 11 and the main shell 10 are integrally molded using a moldable material, and the resulting liquid storage cavity 12 is open or open towards the distal end 120.
[0175] The main housing 10 also includes:
[0176] The second liquid guiding element 30 has a first portion 31 extending along the width direction of the main housing 10, and a second portion 32 extending from the first portion 31 along the longitudinal direction of the main housing 10; the second portion 32 is in fluid communication with the liquid storage cavity 12 through the sheet-like or block-like first liquid guiding element 50; wherein, the second liquid guiding element 30 is conventional flexible plant cotton, and the first liquid guiding element 50 is made of the above-mentioned oriented fibers and has a rigid form;
[0177] Heating element 40 surrounds at least a portion of the first part 31, thereby heating at least a portion of the liquid matrix within the first part 31 to generate an aerosol;
[0178] The support 70 is hollow, cup-shaped or cylindrical, and its interior is used to hold the second liquid guiding element 30 and defines an atomizing chamber surrounding the first part 31; the aerosol generated by the heating element 40 is released into the atomizing chamber and then output to the flue gas output pipe 11; at the same time, the upper end of the support 70 near the liquid storage chamber 12 provides support for the first liquid guiding element 50.
[0179] Specifically, the second liquid-conducting element 30 is a capillary element with internal capillary channels, absorbing and transferring the liquid matrix through capillary wetting. For example, in some embodiments, the second liquid-conducting element 30 is a capillary element made of flexible strip or rod-shaped fibrous material, such as cotton fiber, non-woven fiber, sponge, etc. Or in some other variations, the second liquid-conducting element 30 is a capillary element with internal capillary channels such as porous ceramic body, foam metal, etc. In use, the second portion 32 of the second liquid-conducting element 30 is used to absorb the liquid matrix and then transfer it to the first portion 31 through capillary wetting; the heating element 40 is configured to at least partially surround the first portion 31 and heat at least a portion of the liquid matrix in the first portion 31 to generate an aerosol. Figures 3 to 5 As shown, the heating element 40 has a spiral heating wire structure, and the material can be a resistive metal such as iron-chromium-aluminum alloy, nickel-chromium alloy, etc.
[0180] In the optional implementation, Figure 5 The first portion 31 of the second liquid guiding element 30 has an extension length of approximately 9 mm, and the second portion 32 has an extension length of approximately 7.5 mm. The inner diameter of the heating element 40 is approximately in the range of 2.3 to 2.6 mm.
[0181] In implementation, the first liquid guiding element 50 is a sheet-like or block-like organic porous fiber extending along the cross-sectional direction of the main housing 10. After assembly, the upper surface of the first liquid guiding element 50, near the liquid storage cavity 12, faces the liquid storage cavity 12 and is used to absorb the liquid matrix, while the lower surface, away from the liquid storage cavity 12, transfers the liquid matrix to the second portion 32 of the contacting second liquid guiding element 30, such as... Figure 5 As indicated by the middle arrow R1. Furthermore, the first liquid guiding element 50 is provided with a first insertion hole 51 through which the flue gas transmission pipe 11 passes.
[0182] In specific implementation, the first liquid guiding element 50 is made of 138# rigid synthetic organic polymer fiber cotton, with a viscosity of 0.1~0.9mg / mm. 3 The density is [not specified]; the overall weight of the first liquid-conducting element 50 is approximately 0.04–0.06 g. The first liquid-conducting element 50 is prepared from oriented fibers that are substantially oriented along their length. For example, [not specified]. Figure 6 The image shows a microscopic morphology of polypropylene fibers with oriented arrangement in one embodiment. The oriented fibers are arranged along the length of the first liquid guiding element 50, which makes the first liquid guiding element 50 exhibit strong bending resistance and thus a rigid characteristic.
[0183] See further Figure 7 and Figure 8 As shown, the retaining structure inside the support 70 for holding the second fluid guiding element 30 includes:
[0184] A retaining cavity 71, which extends along the width direction of the main housing 10 and is disposed on the inner bottom wall, is used to retain the first portion 31 of the second liquid guiding element 30; and a retaining cavity 72, which extends along the longitudinal direction of the main housing 10, is used to retain the second portion 32 of the second liquid guiding element 30.
[0185] exist Figure 7 and Figure 8 In the preferred embodiment shown, the bracket 70 is preferably made of a flexible material such as silicone or thermoplastic elastomer, and a first rib 76 extending circumferentially is provided on the outer wall of the first support portion 71; and / or, a second rib 75 extending axially is provided on the outer wall of the retaining cavity 72. In this embodiment, the first rib 76 and the second rib 75 are used to seal the gap between the bracket 70 and the main housing 10.
[0186] Regarding the airflow path design during the suction process, see [reference needed]. Figure 3 In the embodiment shown, the bracket 70 is also provided with a second air inlet 77 facing the end cap 20, which is used to allow external air entering from the first air inlet 22 to enter the atomizing chamber inside the bracket 70; and then carry the aerosol in the atomizing chamber out through the flue gas transmission pipe 11 that passes through the first insertion hole 51.
[0187] Further according to Figure 7 and Figure 8 As shown, the inner wall of the support 70 is provided with a plurality of longitudinally extending protrusions 73, and capillary grooves 731 are formed between the protrusions 73 to adsorb and retain the aerosol condensate in the atomization chamber. In practice, the protrusions 73 have a width of approximately 0.5 to 1.5 mm, and the width of the capillary grooves 731 is less than 2 mm.
[0188] See further Figure 7 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the flue gas output pipe 11 has a first notch 111 at the air inlet end opposite to the nozzle port A; preferably, there are two first notches 111, which are arranged opposite each other along the thickness direction of the main housing 10. In conjunction with the first notch 111, the bracket 70 has a protruding rib 74 that extends at least partially into the first notch 111. After assembly, the two side surfaces of the protruding rib 74 do not contact the two side surfaces of the first notch 111, and according to... Figure 12 A certain distance is maintained between the central convex ridge 74 and the two side surfaces of the first notch 111. This distance is further controlled to be less than 2mm, thereby forming a capillary channel between them. The capillary force of this channel adsorbs and guides the condensate falling or flowing to the inlet end of the flue gas outlet pipe 11 into the atomizing chamber of the support 70, such as... Figure 12As indicated by the middle arrow R4, this prevents condensate from accumulating inside the flue gas outlet pipe 11 and forming a liquid column, thus alleviating or eliminating the problem of condensate being drawn in.
[0189] according to Figure 7 and Figure 8 As shown, in order to ensure that the convex rib 74 can extend into the first notch 111 of the flue gas outlet pipe 11, the convex height of the convex rib 74 is greater than the convex height of the convex rib 73, and the width is the same as that of the convex rib 73. Further in... Figure 8 In the preferred embodiment shown, the protrusion height of the convex ridge 74 is variable, specifically, the upper part along the longitudinal direction is higher than the other part.
[0190] exist Figure 9 In the embodiment shown, the cross-sectional shape of the flue gas output pipe 11 is elliptical. This elliptical shape has its major axis B1 along the width direction of the main housing 10 and its minor axis B2 along the thickness direction of the main housing 10. Consequently, condensate in the flue gas output pipe 11 tends to accumulate at the end with a larger curvature along the major axis B1. Furthermore, the end of the flue gas output pipe 11 is provided with a second notch 112 near at least one side along the width direction of the main housing 10. This second notch 112 creates a hollow space at the end with a larger curvature along the major axis B1, thereby eliminating condensate accumulation there and directing it to accumulate more near the first notch 111. This facilitates the guidance of the condensate into the atomizing chamber with the cooperation of the protrusion 74.
[0191] exist Figure 9 In the preferred embodiment shown, the first notch 111 has a width greater than that of the second notch 112; the width of the first notch 111 in the embodiment is approximately 2.4 mm, and the width of the second notch 112 is approximately 1 mm.
[0192] exist Figure 11 and Figure 12 In the embodiment shown, the flue gas outlet pipe 11 has an inclined pipe wall 113 near the first notch 111; in use, the aerosol condensate on the inner wall of the flue gas outlet pipe 11 flows along... Figure 12 As indicated by the middle arrow R4, the fluid is guided from the inclined tube wall 113 towards the first notch 111, and then adsorbed onto the surface of the protrusion 74 by the capillary channel formed by the protrusion 74 and the first notch 111, before flowing downwards into the atomizing chamber within the support 70. Furthermore... Figure 5 and Figure 12 As can be seen from the above, the protruding ridge 74 and the surface of the first notch 111 are not in contact.
[0193] During use, as the liquid matrix is consumed, the negative pressure inside the storage chamber 12 gradually increases, affecting the smooth flow of the liquid matrix from the storage chamber 12 to the second liquid guiding element 30. Therefore, the atomizer 100 is equipped with a pressure balancing channel to replenish air into the storage chamber 12, reducing the negative pressure and ensuring smooth flow of the liquid matrix. See details... Figures 7 to 10 The pressure balance channel consists of two sequentially connected channel sections, namely... Figure 7 and Figure 8 The first channel section indicated by the middle arrow R31 and Figure 10 The second channel section indicated by the middle arrow R32; specifically:
[0194] At least one protruding rib 14 is provided on the inner wall of the main housing 10 near both sides in the width direction, specifically in Figure 9 and Figure 10 There are two central convex ribs 14, with a certain distance 141 between them. This distance 141, in conjunction with the structural arrangement... Figure 3 The peripheral sidewall of the medium-hard first fluid guiding element 50 has a flat portion 52, which abuts against the protrusion 14 after assembly, thereby defining and keeping the gap 141 from being filled or blocked.
[0195] Furthermore, an air groove 79 is provided on the surface of the support 70 near the first liquid guiding element 50. Figure 7 and Figure 8 The air groove 79 is located at both ends of the support 70 near its width; one side of the air groove 79 communicates with the space inside the support 70, i.e., the atomizing chamber, and the other side communicates with the aforementioned spacing 141, thus allowing the air in the atomizing chamber to move along... Figure 7 and Figure 8 After the middle arrow R31 passes through the air groove 79, it continues along... Figure 10 As indicated by the middle arrow R32, the liquid enters the reservoir 12 of the main housing 10 through the gap 141, relieving or eliminating the negative pressure in the reservoir 12.
[0196] exist Figure 8 and Figure 9 In the preferred embodiment shown, the main housing 10 is further provided with a few protruding ridges 13, which are used to abut against and press against the first liquid guiding element 50 from the upper surface of the first liquid guiding element 50 after assembly.
[0197] Similarly, a groove 711 extending along the thickness direction of the main housing 10 is provided on the wall of the retaining cavity 71. This groove 711 is located on both sides of the portion of the heating element 40 or the first portion 31 surrounded by the heating element 40 along the width direction of the main housing 10. Ultimately, a gap or space is formed between the portion near the atomization area heated by the heating element 40 and the first portion 31 to buffer the liquid matrix and prevent the liquid matrix from flowing directly and quickly to or being transferred to the portion surrounded by the heating element 40, thus slowing down oil splattering.
[0198] See Figure 7 and Figure 8 The inner wall of the cavity 72 has a groove 722 extending longitudinally from the upper end to the groove 711; this groove 722 is used to adsorb and buffer the liquid matrix that seeps out from the second channel portion of the pressure balance channel during air compensation, and can also regulate the efficiency of the liquid matrix flowing on the surface of the second portion 32. Figure 8 It can be seen that the upper end of the groove 722 is connected to the air groove 79; therefore, when the liquid matrix in the liquid storage chamber 12 seeps into the air groove 79 in the direction indicated by arrow R32, it can be adsorbed into the groove 722 and flow downwards, as shown in the image. Figure 13 As indicated by the middle arrow R4.
[0199] In a preferred embodiment, the groove 722 is a capillary groove with a width and / or depth of less than 2 mm, which adsorbs and transfers the liquid matrix through capillary wetting. In a more preferred embodiment, the groove 722 has a width and / or depth of approximately 0.5 mm to 1.5 mm.
[0200] Further according to Figure 8 As shown, the retaining cavity 72 and the retaining cavity 71 are separated by a groove 711, thus making them discontinuous. Furthermore, the surface of the retaining cavity 72 is divided into at least two discontinuous portions by the groove 722. Similarly, the surface of the retaining cavity 71 is divided into at least two discontinuous portions by the groove 711.
[0201] In this implementation, the extension length of the groove 722 is greater than that of the second portion 32, extending at least from the air groove 79 into the retaining cavity 71, and is at least partially adjacent to the surface of the first portion 31. Therefore, in use, the groove 722 can directly supply the liquid matrix to the first portion 31.
[0202] See further Figure 7 and Figure 8 As shown, the air recess 79 is defined by the protrusion 721 surrounding the retaining cavity 72 at the upper end of the support 60. As shown in the figure, the air recess 79 is at least partially curved and surrounds the protrusion 721 of the retaining cavity 72.
[0203] Figure 14Another perspective view of the heating element 40 is shown, including a first electrical pin 41 and a second electrical pin 42 arranged opposite each other along the length direction, and a first spiral coil 410 and a second spiral coil 420 extending between the first electrical pin 41 and the second electrical pin 42. In an embodiment, the first spiral coil 410 and the second spiral coil 420 are simultaneously powered by the first electrical pin 41 and the second electrical pin 42, and are thus connected in parallel. Structurally, the first spiral coil 410 and the second spiral coil 420 are arranged close together side by side. In an optional embodiment, the first spiral coil 410 and the second spiral coil 420 have approximately 3 to 10 turns or windings, and an extension length of approximately 4 to 7 mm. Figure 13 They have 5 turns or windings and a design length of 6.5 mm.
[0204] according to Figure 14 As shown, the first spiral coil 410 and the second spiral coil 420 are not arranged to overlap in the radial direction, but are arranged side by side or staggered in the axial direction. At least after assembly, they are each positioned differently relative to the first part 31 along the extension direction of the first part 31, thus having a larger contact area with the first part 31 and higher heating efficiency.
[0205] The wire material used for the first electrical pin 41 and the second electrical pin 42 has a larger diameter than the wire material used for the first spiral coil 410 and the second spiral coil 420; that is, the first electrical pin 41 and the second electrical pin 42 are made of relatively thick wire, while the first spiral coil 410 and the second spiral coil 420 are made of relatively thin wire, thus facilitating the connection of their two ends to the first electrical pin 41 and the second electrical pin 42. In a specific implementation, the first electrical pin 41 and the second electrical pin 42 are made of wire with a diameter of approximately 0.25 mm, while the first spiral coil 410 and the second spiral coil 420 are made of wire with a diameter of 0.15 mm.
[0206] In an optional implementation, the first helical coil 410 and the second helical coil 420 are made of a suitable resistive metal or alloy, such as iron-chromium-aluminum, nickel-chromium alloy, etc., and have a relatively large temperature coefficient of resistance; the first electrical pin 41 and the second electrical pin 42 provide the function of electrical pins and are made of a metal or alloy with high conductivity and low resistivity, such as gold, silver, copper, etc., or are slender pins made by forming the aforementioned metal plating on the outer surface of the filamentary substrate.
[0207] See further Figure 14 As shown, the first electrical pin 41 includes an annular support portion 411 and an electrical connection portion 412; wherein,
[0208] The annular support portion 411 is connected to the first helical coil 410 and the second helical coil 420, and their helical dimensions, such as the outer or inner diameter, are substantially the same; furthermore, during assembly, the annular support portion 411 can also surround the first portion 31 of the second liquid guiding element 30, and thus, after assembly, the annular support portion 411 of the first electrical pin 41 provides support for the first portion 31 of the second liquid guiding element 30. The electrical connection portion 412 extends through the bracket 70 for contact or welding with the second electrical contact 21.
[0209] See further Figure 13 As shown, after assembly, the first spiral coil 410 and the second spiral coil 420 of the heating element 40 do not contact the inner wall of the bracket 70 and / or the wall of the retaining cavity 71; instead, they are held on the inner wall of the bracket 70 and / or the wall of the retaining cavity 71 by the annular support portion 411 of the first electrical pin 41, thereby supporting the heating element 40; during operation, the first electrical pin 41 and the second electrical pin 42 have a lower temperature than the first spiral coil 410 and the second spiral coil 420, avoiding thermal damage to the bracket 70.
[0210] See further Figure 3 and Figure 13 As shown, the electrical connection portion 412 of the first electrical pin 41 is bent into a hook shape; in the assembly structure, the bracket 70 has a lead hole 781 extending from the inner wall to the surface facing the end cover 20, and a contact hole 782 provided facing the end cover 20 for at least partially accommodating the second electrical contact 21; after assembly, the electrical connection portion 412 extends or bends into the contact hole 782 after passing through the lead hole 781 to form a conductive connection with the second electrical contact 21.
[0211] Of course, the second electrical pin 42 has the same construction, connection and assembly as the first electrical pin 41.
[0212] In an optional embodiment, the heating element 40 has an inner diameter of about 2 to 4 mm, preferably 2.3 mm to 2.6 mm; and the heating element 40 has a resistance of about 0.5 to 2 ohms.
[0213] In a more preferred embodiment, the spiral coil portion of the heating element 40, consisting of a first spiral coil 410 and a second spiral coil 420 arranged side-by-side, has a length of approximately 4.2 to 5 mm; Figure 14 It includes 5 turns or windings, each with a length of approximately 1 mm.
[0214] See further Figures 15 to 17 An exploded view and a cross-sectional view of an atomizer 100a according to another embodiment are shown; the atomizer 100a includes:
[0215] The main housing 10a has a longitudinally extending flue gas outlet pipe 11a and a liquid storage chamber 12a defined by the flue gas outlet pipe 11a and the inner wall of the main housing 10a.
[0216] The second liquid guiding element 30a has a first portion 31a extending along the width direction of the main housing 10a, and a second portion 32a extending from the first portion 31a along the longitudinal direction of the main housing 10a; the second portion 32a is in fluid communication with the liquid storage cavity 12a through the sheet-like or block-like first liquid guiding element 50a; wherein, the first liquid guiding element 50a is made of the above-mentioned oriented fibers and has a rigid form; the second liquid guiding element 30a is a rigid porous body, such as porous ceramic;
[0217] A heating element 40a is formed on the first portion 31a, thereby heating at least a portion of the liquid matrix in the first portion 31a to generate an aerosol;
[0218] The support 70a is hollow, cup-shaped or cylindrical, and its interior is used to hold the second liquid guiding element 30a and defines an atomizing chamber surrounding the first part 31a; the aerosol generated by the heating element 40a is released into the atomizing chamber and then output to the flue gas output pipe 11a; at the same time, the upper end of the support 70a near the liquid storage chamber 12a provides support for the first liquid guiding element 50a;
[0219] End cap 20a is used to seal the open end of the main housing 10a, and a second electrical contact 21a and a first air inlet 22a are provided thereon;
[0220] The second electrical contact 21a extends from the end cap 20a through the contact hole 78a on the bracket 70a and abuts against the heating element 40a, and is used to supply power to the heating element 40a.
[0221] See further Figure 18 and Figure 19 As shown, the second liquid-conducting element 30a, made of porous ceramic body, is generally U-shaped. The second liquid-conducting element 30a has an approximate length dimension d1 of 13 mm, a width dimension d2 of approximately 3 mm, and a height dimension d4 of approximately 5 mm. The first part 31a of the second liquid-conducting element 30a has a length dimension d11 of approximately 7 mm, meaning the U-shaped opening is also 7 mm in size; the height dimension d41 of the first part 31a is approximately 2 mm. The second part 32a of the second liquid-conducting element 30a has a length dimension d3 of approximately 3 mm.
[0222] The first portion 31a of the second liquid guiding element 30a, facing away from the outer surface 310a of the U-shaped opening, is constructed in a generally planar shape, and this outer surface 310a is configured as an atomizing surface 310a for atomizing the liquid matrix. A heating element 40a is configured to be attached to this atomizing surface 310a. In practice, the liquid matrix drawn in by the second portion 32a is transferred to the atomizing surface 310a, heated and atomized by the heating element 40a to generate an aerosol, which is then released from the atomizing surface 310a into the atomizing chamber within the support 70a, and subsequently output with the suction airflow.
[0223] Heating element 40a in Figure 19 The device has conductive portions 41a at both ends and a resistive heating trajectory portion 42a that meanders and extends along the length of the first portion 31a. In use, a second electrical contact 21a abuts against the conductive portion 41a to supply power to the resistive heating trajectory portion 42a. In some embodiments, the resistive heating trajectory portion 42a is a trajectory formed by printing, etching, or other methods. In still other embodiments, the resistive heating trajectory portion 42a is a patterned trajectory.
[0224] In this implementation, the second liquid guiding element 30a is a rigid porous body. After assembly, the front end of the second part 32a of the second liquid guiding element 30a abuts against the lower surface of the first liquid guiding element 50a, thereby providing support for the first liquid guiding element 50a and receiving the liquid matrix from the first liquid guiding element 50a.
[0225] further Figure 20 and Figure 21 A schematic diagram of the structure of an atomizer 100b according to another embodiment is shown. In this atomizer 100b, a hole 53b extending along the thickness direction is provided on the first liquid guiding element 50b; and the second part 321b of the second liquid guiding element 30b is exposed in the liquid storage chamber 12b through the hole 53b on the lower surface of the first liquid guiding element 50b, thus directly absorbing the liquid matrix in the liquid storage chamber 12b. Specifically:
[0226] The second portion 321b of the second liquid guiding element 30b has an insertion section 321b with a relatively small outer diameter. This insertion section 321b passes through the hole 53b of the first liquid guiding element 50b and communicates with the liquid storage chamber 12b. Simultaneously, the cross-sectional width or length of the insertion section 321b is 2 mm. This creates a step at the joint of the second portion 321b of the insertion section 321b during implementation. This step abuts against the lower surface of the first liquid guiding element 50b, thereby providing support and retention for the first liquid guiding element 50b.
[0227] Figure 22A schematic diagram of a second liquid guiding element 30f, which can be used in an atomizer 100b, is shown in yet another embodiment. In this embodiment, the upper surface of the first portion 31f of the second liquid guiding element 30f is configured as an atomizing surface 310f; a heating element 40f is formed on the atomizing surface 310f defined by the upper surface. Meanwhile, after assembly, the heating element 40f and / or the atomizing surface 310f face the first liquid guiding element 30b.
[0228] In the corresponding implementation, the heating element 40f is formed on the atomized surface 310f by means of printing, deposition, etching, mounting, etc. The conductive part 41f of the heating element 40f is connected to the second electrical contact 21b through spring contacts, wire bonding, etc., thereby supplying power to the heating element 40f.
[0229] Alternatively, in other variations, the second liquid guiding element 30f may have other shapes or configurations, such as an L-shape.
[0230] Figures 23 to 25 A schematic diagram of the structure of an atomizer 100c according to yet another embodiment is shown; in this embodiment, the atomizer 100c includes:
[0231] The main housing 10c has a suction nozzle A at its proximal end; the main housing 10c has a smoke output pipe 11c inside and a liquid storage chamber 12c defined by the smoke output pipe 11c; of course, the liquid storage chamber 12c is open at its distal end.
[0232] The end cap 20c is attached to the opening at the far end of the main housing 10c, thereby defining the outer housing of the atomizer 100c with the main housing 10c.
[0233] The first liquid guiding element 50c is in the shape of a sheet or block perpendicular to the main housing 10c. After assembly, it spans or covers the opening of the liquid storage cavity 12c, thereby sealing the liquid storage cavity 12c so that the liquid matrix in the liquid storage cavity 12c can leave substantially only through the first liquid guiding element 50c. In a preferred embodiment, the first liquid guiding element 50c is generally elliptical in shape. In a preferred embodiment, the first liquid guiding element 50c uses the same rigid organic cotton as the first liquid guiding element 50c used in the above embodiments.
[0234] The atomizer 100c also includes:
[0235] Second liquid guiding element 30c, see Figure 24As shown, the whole has a first sidewall 31c and a second sidewall 32c opposite each other along the thickness direction, and a notch located between the first sidewall 31c and the second sidewall 32c; the second liquid guiding element 30c also has an atomizing surface 310c that is opposite to the first sidewall 31c and / or the second sidewall 32c and / or the notch along the longitudinal direction. In this preferred embodiment, the second liquid guiding element 30c is rigid and adopts a porous body, such as a porous ceramic body, as described in the above embodiments.
[0236] Heating element 40c is attached to atomizing surface 310c to heat at least a portion of the liquid matrix within the second liquid guiding element 30c to generate an aerosol, which is then released from atomizing surface 310c.
[0237] The third liquid guiding element 80c transfers the liquid matrix between the first liquid guiding element 50c and the second liquid guiding element 30c, transferring the liquid matrix absorbed by the first liquid guiding element 50c to the second liquid guiding element 30c. In a preferred embodiment, the third liquid guiding element 80c is flexible, such as a sponge. (See attached image for assembly details.) Figure 26 As shown, the third liquid-conducting element 80c is at least partially accommodated and held within the notch 33c of the second liquid-conducting element 30c, and is in contact with both the first liquid-conducting element 50c and the second liquid-conducting element 30c, thereby forming fluid communication with them to transfer the liquid matrix between them. As shown in the figure, the third liquid-conducting element 80c is generally block-shaped, columnar, or strip-shaped, with its upper end abutting against the first liquid-conducting element 50c and its lower end abutting against the second liquid-conducting element 30c, thereby facilitating liquid transfer between them.
[0238] In some variable embodiments, for example Figure 30 The second liquid guiding element 30e shown has a groove 33e on its upper surface, and the groove 33e at least partially accommodates and holds the third liquid guiding element 80c; and after assembly, the surface of the third liquid guiding element 80c and the second liquid guiding element 30e defining the groove 33e are in contact or abut against each other to form fluid communication, thereby transferring the liquid matrix.
[0239] Alternatively, in other variations, the second liquid guiding element 30c / 30e may have a clamping port, a retaining cavity, a recess, or other accommodating or supporting structures, thereby at least partially accommodating the third liquid guiding element 80c and providing support or retention for the third liquid guiding element 80c.
[0240] The bracket 70c is used to accommodate and hold the second liquid guiding element 30c and the third liquid guiding element 80c; and at least partially defines an atomizing chamber for aerosol release with the atomizing surface 310c. The bracket 70c also has an electrode hole 78c through which a second electrical contact 21c passes and abuts against the heating element 40c, and a second air inlet 77c for allowing external air entering through the first air inlet 22c to enter the atomizing chamber. The bracket 70c also provides at least partial support and holding for the first liquid guiding element 50c by abutting against its lower surface. After assembly, the flue gas outlet pipe 11c passes through the first insertion hole 51d on the first liquid guiding element 50c and communicates with the airflow of the atomizing chamber within the bracket 70c to output aerosol.
[0241] See further Figure 25 and Figure 26 As shown, after assembly, the third liquid guiding element 80c has an exposed portion 81c that is exposed outside the notch of the second liquid guiding element 30c along the length direction of the second liquid guiding element 30c; after assembly, the exposed portion 81c is supported by the bracket 70c.
[0242] In the atomizer 100c of this embodiment, the airflow structure or path is further described below. Figure 27 As indicated by the middle arrow R2: After assembly, gaps are maintained between the first sidewall 31c of the second liquid guiding element 30c and the inner wall of the support 70c along the thickness direction, and between the second sidewall 32c of the second liquid guiding element 30c and the inner wall of the support 70c, thereby forming a channel 71c; during the suction process, after entering the atomizing chamber defined by the atomizing surface 310c through the second air inlet 77c, it carries the aerosol across the second liquid guiding element 30c through the channel 71c, and then outputs to the flue gas output pipe 11c at the central part near the flue gas output pipe 11c.
[0243] according to Figure 24 , Figure 27 and Figure 30 As shown, the inner wall of the bracket 70c is provided with a locking protrusion 72c for fixing and holding the second liquid guiding element 30c; after assembly, the upper end face of the first side wall 31c and / or the second side wall 32c of the second liquid guiding element 30c abuts against the locking protrusion 72c, thereby making the second liquid guiding element 30c stably held in the bracket 70c.
[0244] See further Figure 27 As shown, in order to alleviate the negative pressure in the liquid storage chamber 12c, the support 70c has grooves 79c on both sides along the width direction, which are connected to the airflow in the space inside the support 70c. This allows the air entering the atomizing chamber from the outside to enter the grooves 79c along the arrow R3, and then enter the liquid storage chamber 12c through the gap between the straight part 52c on the peripheral side wall of the first liquid guiding element 50c and the main housing 10c.
[0245] Further participation Figure 28 and Figure 29 As shown, in this embodiment, the second liquid guiding element 30c further includes the following components:
[0246] The base portion 34c is located at the lower end of the second liquid guiding element 30c in the longitudinal direction and extends between the first sidewall 31c and the second sidewall 32c; at the same time, the extension length of the base portion 34c in the length direction of the second liquid guiding element 30c is the same as the extension length of the first sidewall 31c and / or the second sidewall 32c; as shown in the figure, the lower surface of the base portion 34c is used as the atomizing surface 310c, and the lower end of the third liquid guiding element 80c abuts against the upper surface of the base portion 34c;
[0247] The connecting portion 35c is located on the upper end side of the second liquid guiding element 30c in the longitudinal direction and is arranged close to the central part of the second liquid guiding element 30c; similarly, the connecting portion 35c extends between the first sidewall 31c and the second sidewall 32c; and the extension length of the connecting portion 35c in the length direction of the second liquid guiding element 30c is less than the extension length of the first sidewall 31c and / or the second sidewall 32c and / or the base portion 34c; thus, a notch 33c is formed in the area not covered by the connecting portion 35c.
[0248] Meanwhile, a space 36c extending along the length direction is defined between the connecting portion 35c and the base portion 34c; after assembly, the space 36c is surrounded or shielded by the third liquid guiding element 80c; thus, the space 36c can be used to receive or buffer the liquid matrix seeping from the surface of the third liquid guiding element 80c, thereby adjusting the amount or efficiency of the liquid matrix supplied to the atomizing surface 310c.
[0249] Further according to Figure 29 As shown, after assembly, the connection portion 35c of the second liquid guiding element 30c is at least partially opposite to the first insertion hole 51c of the first liquid guiding element 50c along the longitudinal direction of the main housing 10c. Thus, in practice, the connection portion 35c can be configured to receive aerosol condensate falling from the flue gas output pipe 11c.
[0250] See further Figure 31 The diagram shows a cross-sectional view of the bracket 70c from one perspective. The bracket 70c has the following internal features or structures:
[0251] The first step 73c is used to support the second liquid guiding element 30c. Specifically, after assembly, at least a portion of the longitudinal end of the atomizing surface 310c of the second liquid guiding element 30c abuts against the first step 73c. At the same time, the electrode hole 78c also extends or penetrates into the first step 73c, so that the second electrical contact 21c can abut against the conductive portion of the heating element 40c on the atomizing surface 310c after penetrating the electrode hole 78c, thereby supplying power to the heating element 40c.
[0252] The second step 74c is used to support the exposed portion 81c of the third liquid guiding element 80c that protrudes from the notch 33c of the second liquid guiding element 30c.
[0253] from Figure 31 As can be seen, the first step 73c and the second step 74c have different heights along the longitudinal direction. The first step 73c and the second step 74c are arranged on both sides of the inner surface of the support 70c near the width direction.
[0254] See further Figure 31 As shown, the first step 73c and the inner bottom wall 76c of the support 70c have different heights in the longitudinal direction. Therefore, after assembly, the atomizing surface 310c of the second liquid guiding element 30c and the inner bottom wall 76c of the support 70c can have a gap space 340c, thereby forming an atomizing chamber to accommodate aerosols. In this embodiment, according to... Figure 31 As shown, capillary grooves 75c are provided on the side wall of the spacing space 340c and the inner bottom wall 76c. The capillary grooves 75c have a width of about 0.5 to 2 mm to absorb the aerosol condensate in the atomization chamber.
[0255] Figures 32 to 35 A schematic diagram of the structure of an atomizer 100d according to yet another embodiment is shown; the atomizer 100d in this embodiment includes:
[0256] The main housing 10d has a suction nozzle A at its proximal end; the main housing 10d has a flue gas outlet pipe 11d inside, and a liquid storage chamber 12d defined by the flue gas outlet pipe 11d; of course, the liquid storage chamber 12d is open at its distal end.
[0257] The end cap 20d is attached to the opening at the far end of the main housing 10d, thereby defining the outer housing of the atomizer 100d with the main housing 10d;
[0258] The first liquid guiding element 50d is in the shape of a sheet or block perpendicular to the main housing 10d; in a preferred embodiment, the first liquid guiding element 50d is generally elliptical in shape; in a preferred embodiment, the first liquid guiding element 50d is made of the same hard organic cotton used in the first liquid guiding element 50d of the above embodiments.
[0259] Second liquid guiding element 30d, see [reference] Figure 35 As shown, the overall shape is a sheet or plate-like form perpendicular to the longitudinal direction of the main housing 10d; its upper surface along the thickness direction is in fluid communication with the first liquid guiding element 50d to receive the liquid matrix; its lower surface along the thickness direction is configured as an atomizing surface 310d. In this preferred embodiment, the second liquid guiding element 30c is rigid and adopts a porous body, such as a porous ceramic body, as described in the above embodiments.
[0260] The heating element 40d is formed on the atomizing surface 310d and is used to heat at least a portion of the liquid matrix within the second liquid guiding element 30d to generate an aerosol.
[0261] The third liquid guiding element 80d is positioned between the first liquid guiding element 50d and the second liquid guiding element 30d along the longitudinal direction of the main housing 10d to transfer the liquid matrix between them.
[0262] See further Figure 33 and Figure 35 As shown, the third liquid guiding element 80d is generally U-shaped, including a third portion 81d along the longitudinal direction perpendicular to the main housing 10d, and a fourth portion 82d extending from the third portion 81d toward the first liquid guiding element 50d; after assembly, the third portion 81d contacts and abuts against the upper surface of the second liquid guiding element 30d, thereby forming fluid communication with the second liquid guiding element 30d, and the fourth portion 82d extends to the lower surface of the first liquid guiding element 50d, thereby forming fluid communication with the first liquid guiding element 50d.
[0263] exist Figure 34 and Figure 35 In the preferred embodiment shown, the extension length of the third portion 81d is greater than the length of the second liquid guiding element 30d, so that after assembly, the third portion 81d at least partially protrudes relative to the second liquid guiding element 30d, and the protruding portion abuts against the bracket 70d and is at least partially supported by the bracket 70d. Similarly, the third portion 81d is also at least partially supported by the second liquid guiding element 30d by abutting against it.
[0264] See further Figure 36 As shown, the support 70d has longitudinally extending windows 76d on both side walls along its thickness direction. After assembly, these windows 76d define an output channel between themselves and the inner wall of the main housing 10d. Specifically, the longitudinal length of these windows 76d at least covers the atomizing chamber 340d defined by the atomizing surface 30d of the second liquid guiding element 30d, thereby allowing air entering the atomizing chamber 340d from the second air inlet 77d to enter the channel through the window 76d; and then outputs to the flue gas output pipe 11d through the U-shaped opening across the third liquid guiding element 80d as shown by arrow R2 in the figure.
[0265] See further Figure 36 In this embodiment, a groove 79d is provided on the surface of the support 70c adjacent to the first liquid guiding element 50d. This groove is in airflow communication with the output channel indicated by arrow R2. Therefore, after assembly, when the negative pressure in the liquid storage chamber 12d exceeds a certain threshold range, air can sequentially pass through... Figure 36 The first channel portion, defined by the groove 79d, and the second channel portion, defined by the straight portion 52d of the peripheral sidewall of the first liquid guiding element 50d and the inner wall of the main housing 10d, as indicated by the middle arrow R31, enter the liquid storage chamber 12d to relieve the negative pressure.
[0266] See further Figure 37 As shown, the interior of the support 70d in this embodiment has:
[0267] The first protrusion 73d is used to abut against the atomizing surface 310d of the second liquid guiding element 30d, thereby supporting the second liquid guiding element 30d;
[0268] The second protrusion 74d is used to abut against the part of the third liquid guiding element 80d that protrudes or protrudes from the second liquid guiding element 30d, thereby supporting the third liquid guiding element 80d.
[0269] The electrode hole 78d is used to allow the second electrical contact 21d to pass through and abut against the atomizing surface 310d to supply power to the heating element.
[0270] Capillary grooves 75d are formed on the inner bottom wall of the support 70d and on the surface of the space between the first protrusion 73d and the inner bottom wall to adsorb aerosol condensate in the atomization chamber.
