Description

Technical Field

[0001] This invention relates to the field of electronic cigarettes, and more particularly to an atomizer and an electronic cigarette. Background Technology

[0002] Electronic cigarettes are products that heat and atomize a nicotine-containing liquid base into an aerosol for users to inhale. The atomizer is the part of an electronic cigarette that enables atomization, and its structure includes a reservoir for storing the liquid base, a porous body that draws the liquid base from the reservoir, and a heating element that heats and atomizes the liquid base drawn into the porous body. To facilitate aerosol transport during inhalation, the atomizer's outer shell, corresponding to the heating element, has an air intake port for airflow and a vapor delivery tube for aerosol output. During inhalation, external air enters the atomizer through the air intake port, carries the aerosol, and is output through the vapor delivery tube, forming a complete airflow cycle.

[0003] Due to the design of the airflow circulation structure, the liquid matrix that seeps out from the porous body during the use of the atomizer, as well as the condensate formed after cooling during the transmission of the heated aerosol, accumulate inside the atomizer and flow out from the air inlet, causing oil leakage and contamination.

[0004] Based on the above, as an improvement, prior art patent No. 201820119392.7 proposes an atomizer with an air inlet blocking structure. This atomizer uses a baffle that can project onto a plane along the atomizer's axial direction to cover the air inlet, thereby blocking the air inlet and preventing the liquid matrix from flowing out. However, adding the baffle structure increases suction resistance and causes the external airflow entering through the air inlet to diffuse, resulting in some of the generated aerosol being diffused and trapped in the corners, reducing smoke extraction efficiency. Summary of the Invention

[0032] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0033] This invention provides an electronic cigarette product for heating and atomizing a liquid matrix. In one embodiment, a conventional... Figure 1 and Figure 2 Taking the flat cigarette shown as an example, the device includes an atomizer 100 for atomizing a liquid matrix and a power supply device 200 for supplying power to the atomizer 100. The power supply device 200 is also provided with conductive spring pins 210 for connecting and conducting electricity to the atomizer 100, and magnets 220 for magnetically attracting magnetic elements on the atomizer 100.

[0034] For a detailed description of the structure of atomizer 100, please refer to [link / reference]. Figure 3 Schematic diagram of the decomposition and Figure 4 The cross-sectional schematic diagram shows that it includes:

[0035] The hollow cylindrical outer shell 10 has a proximal end and a distal end opposite each other in the axial direction; wherein, according to the needs of normal use, the proximal end is configured as the end for the user to inhale aerosol, and the distal end is configured as the end for assembly connection with the power supply device 200; for ease of description, the outer shell 10 also has a first sidewall 110 and a second sidewall 120 opposite each other in the thickness direction.

[0036] Based on the different uses mentioned above, a smoking port A is provided on the near end of the outer casing 10 for users to perform suction operations; the far end of the outer casing 10 is an open design, on which a detachable end cap 20 is installed. The open structure at the far end is used to install various necessary functional components inside the outer casing 10.

[0037] Furthermore, the interior of the outer casing 10 is provided with a liquid storage chamber 30 for storing a liquid matrix, and an atomizing component 40 for drawing the liquid matrix from the liquid storage chamber 30 and heating and atomizing it; specifically, in Figure 4 In the cross-sectional structural schematic diagram shown, the outer shell 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 outer shell 10 forms a liquid storage chamber 30 for storing the liquid matrix. The first end of the flue gas transmission pipe 11, which is relatively close to the smoking port A, is connected to the second end, which is relatively far from the smoking port A, thereby transmitting the aerosol generated by the atomizing liquid matrix by the atomizing component 40 to the smoking port A for inhalation.

[0038] See Figure 3The atomizing assembly 40 shown may include a porous body 41 for drawing a liquid matrix from the storage chamber 30, and a heating element 42 for heating and atomizing the liquid matrix drawn into the porous body 41. Figure 3 As shown, the porous body 41 in the embodiment may be generally, but is not limited to, a block structure. Depending on the application, it includes a liquid-absorbing surface 411 and an atomizing surface 412 that are opposite to each other along the axial direction of the outer shell 10. Figure 3 The upper and lower surfaces of the blocky porous body 41; wherein, the liquid-absorbing surface 411 is opposite to the liquid storage cavity 30, and absorbs the liquid matrix by directly or indirectly contacting the liquid matrix in the liquid storage cavity 30; the porous structure inside the porous body 41 then conducts the liquid matrix to the atomizing surface 412 for heating and atomization to form an aerosol, which is then released from the atomizing surface 412. Figure 3 In the porous body 41 structure shown, since the liquid absorption surface 411 and the atomizing surface 412 are parallel to each other, the movement direction of the liquid matrix and aerosol in the porous body 41 is perpendicular to the plane where the atomizing surface 412 is located. The movement of aerosol and liquid matrix in the porous body 41 will be smoother, and it is easier to manufacture.

[0039] In some embodiments, the porous body 41 can be made of a hard capillary structure such as porous ceramic, porous glass ceramic, or porous glass. The heating element 42 is preferably formed on the atomizing surface 412 by mixing conductive raw material powder with printing additives to form a slurry, followed by sintering after printing. This ensures that all or most of its surface is tightly bonded to the atomizing surface 412, resulting in high atomization efficiency, low heat loss, and prevention or significant reduction of dry burning. In some embodiments, the heating element 42 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium.

[0040] See further Figures 2 to 4 To facilitate the installation and fixing of the atomizing component 40 and the sealing of the liquid storage chamber 30, a sealing mechanism 50 is also provided inside the outer casing 10. The sealing mechanism 50 includes a silicone sleeve 51, a rigid support sleeve 52, and a silicone seat 53, which both seals the port of the liquid storage chamber 30 and fixes the atomizing component 40 inside.

[0041] In terms of specific structure and shape, the silicone sleeve 51 is generally ring-shaped, with a hollow interior 511 for accommodating the atomizing component 40, and is fitted onto the atomizing component 40 in a flexible and tight manner.

[0042] The support sleeve 52 holds the atomizing assembly 40, on which the silicone sleeve 51 is fitted, and in some embodiments may include a generally elliptical cylindrical main body 521 and a clamping wall 522 extending downward from the bottom surface of the main body 521. The clamping wall 522 is C-shaped, thereby forming a holding cavity 523 within the clamping wall 522 for accommodating and holding the silicone sleeve 51 and the atomizing assembly 40. An airflow channel 524 is provided on the side of the support sleeve 52 opposite to the first sidewall 110 of the outer shell 10 for outputting the aerosol generated by the atomizing surface 412; a first liquid guiding hole 525 is formed on the support sleeve 52 for transferring the liquid matrix to the liquid absorption surface 411.

[0043] The silicone seat 53 is located at the distal end of the liquid storage cavity 30, and its shape is adapted to the cross-section of the inner contour of the outer shell 10, thereby sealing the liquid storage cavity 30 to prevent the liquid matrix from leaking out of the liquid storage cavity 30. Furthermore, to prevent the shrinkage and deformation of the flexible silicone seat 53 from affecting the tightness of the seal, the rigid support sleeve 52 is accommodated within the silicone seat 53 to provide support. Structurally, the silicone seat 53 has two opposing second clamping walls 531 extending downward from the bottom surface, and a receiving cavity 532 is formed between the two second clamping walls 531 to accommodate the main body 521 of the support sleeve 52. Meanwhile, two second liquid guiding holes 533 and one tracheal insertion hole 534 are formed on the silicone base 53; the two second liquid guiding holes 533 correspond to the two first liquid guiding holes 525 on the support sleeve 52, so that the liquid matrix in the liquid storage chamber 30 can flow to the liquid absorption surface 411 of the porous body 41 after passing through the second liquid guiding holes 533 and the first liquid guiding holes 525 and be absorbed; the tracheal insertion hole 534 is used for the lower end of the flue gas transmission pipe 11 to be inserted, and after installation, the flue gas transmission pipe 11 and the airflow channel 524 are in airflow communication, so that the generated aerosol is output to the smoking port A.

[0044] Furthermore, in order to stably fix the sealing mechanism 50 within the atomizer 100, the end cap 20 has two first support arms 21 standing on the top surface of the cap body 21 to support the sealing mechanism 50.

[0045] Meanwhile, the end cap 20 is provided with a first mounting hole 22, a second mounting hole 23, and an air inlet 24. The first mounting hole 22 houses a magnetic element 25, such as a magnet or ferromagnetic material, that can be magnetically attracted to the magnet 220 of the power supply device 200. The second mounting hole 23 houses an electrode post 26, which connects to the conductive spring pin 210 of the power supply device 200 and serves as a power supply electrode to supply power to the heating element 42. The air inlet 24 allows external air to enter the atomizer 10 during the inhalation process.

[0046] For those currently in use, please refer to [link / reference]. Figure 4As shown by the middle arrow R1, the liquid matrix enters the annular space of the silicone sleeve 51 from the liquid storage chamber 30 through the second liquid guide hole 533 and the first liquid guide hole 525, and is absorbed by the liquid absorption surface 411 of the porous body 41. It is then transferred to the atomizing surface 412 and heated and atomized by the heating element 42 to form an aerosol for release.

[0047] To further facilitate the release and transport of aerosols, see [link to relevant documentation]. Figure 3 and Figure 4 As shown, a receiving seat 60 is provided between the end cap 20 and the atomizing surface 412; the receiving seat 60 and the atomizing surface 412 maintain a certain distance to form an atomizing chamber 70 for aerosol release.

[0048] See further Figure 3 and Figure 7 As shown, the air inlet 24 is configured to be located near the second side wall 120 of the outer casing 10, so that it and the airflow channel 524 are located on opposite sides of the atomizing chamber 70. Further details regarding the direction of the suction airflow can be found in [reference needed]. Figure 3 , Figure 5 and Figure 7 As shown, air entering through the air inlet 24 enters the atomizing chamber 70 near the second sidewall 120, then passes through the atomizing chamber 70 along the thickness direction of the outer shell 10 and is output to the smoke transmission pipe 11 through the airflow channel 524 near the first sidewall 110. When the user inhales, the airflow can pass through the entire atomizing chamber 70, thereby maximizing the outflow of aerosols within the atomizing chamber 70 with the airflow and reducing stagnation, thereby improving smoke extraction efficiency and preventing the formation of condensate within the atomizing chamber 70.

[0049] See further Figure 5 , Figure 6 and Figure 7 As shown, the receiving seat 60 is generally block-shaped and has opposing upper surfaces 61 and lower surfaces 62. The upper surface 61 is opposite to the atomizing surface 412 and maintains a gap to form the atomizing cavity 70. In the design, the upper surface 61 is inclined, specifically inclined upwards along the direction close to the first sidewall 110. One function of this is to guide the airflow through the inclined design, such as... Figure 6 The airflow indicated by the middle arrow R2 flows out at an angle under the guidance of the upper surface 61; on the other hand, the condensate formed by the aerosol in the atomizing chamber 70 after encountering cold air, and the liquid matrix leaking downward from the atomizing component 40, can be received by the upper surface 61 and flow along the inclined upper surface 61. Figure 6 The flow gradually moves in the direction of the middle arrow R3 and falls off the drainage sidewall 64.

[0050] Furthermore, the receiving base 60 is also provided with a through hole 63 extending through the length of the atomizer 100, which is used to allow the electrode post 26 to pass through the through hole 63 and abut against the two ends of the heating element 42 on the atomizing surface 412 for conduction.

[0051] exist Figure 7 In the preferred embodiment shown, the condensate flowing down from the receiving seat 60 gradually flows into the gap between the lower surface 62 and the end cap 20, and the height of the port of the air inlet 24 located inside the end cap 20 is between the highest and lowest points of the inclined upper surface 61, so that the air flowing out from the port of the air inlet 24 is directed toward a certain middle part of the upper surface 61, so that the upper surface 61 can at least partially guide the airflow passing through the atomizing chamber 70.

[0052] Furthermore, to prevent condensate dripping from the receiving seat 60 onto the end cap 20 from seeping out from the first mounting hole 22 and the second mounting hole 23 of the end cap 20. Figure 8 A schematic diagram of another preferred embodiment of the receiving seat 60 is shown, in which a plurality of grooves 621a are provided on the lower surface 62a opposite to the end cap 20. These grooves 621a utilize capillary action to absorb and retain condensate, further preventing leakage of condensate or the received liquid matrix. Figure 8 It can also be seen that the grooves 621a extend along the thickness direction of the atomizer 100, that is, parallel to the direction in which the airflow passes through the atomizing chamber 70, thereby promoting adsorption through the hydrodynamic force of the airflow. In other variations, these grooves 621a can also be arranged in a bent, intersecting, or other manner. Alternatively, in other variations, the grooves 621a can be replaced with other capillary structures that can adsorb condensate or liquid matrix through capillary action, such as structures with capillary pores or irregularities.

[0053] Or in yet another preferred implementation, see Figure 9 As shown, the receiving seat 60b is composed of two parts, specifically including:

[0054] The housing 610b has an upper surface 61b and a lower surface 62b. The upper surface 61b is an inclined arc surface used to guide airflow and collect condensate. The housing 610b has an open chamber located on the lower surface 61b. A liquid-absorbing component 620b is installed in this chamber to absorb and retain condensate. The liquid-absorbing component 620b is made of materials such as sponge, porous ceramic, or foam, or has a material that can absorb liquid through capillary action. When the collected condensate flows from the drainage sidewall 64b into the gap between the end cap 20, it can be absorbed by the surface of the liquid-absorbing component 620b exposed on the open surface of the housing 610b, thereby eliminating leakage of condensate or liquid matrix.

[0055] In a further preferred embodiment, the area of ​​the upper surface 61 of the receiving seat 60, preferably projected along the axial direction of the atomizer 100, is larger than that of the atomizing surface 412, and completely covers the atomizing surface 412. Meanwhile, from... Figure 5 and Figure 7 It can be seen that the part of the end cap 20 that forms the air inlet 24 does not contact the flow-guiding side wall 64 of the receiver 60 along the thickness direction of the atomizer 100 and maintains a certain distance of about 5mm, so that the condensate can be smoothly guided from the flow-guiding side wall 64 of the receiver 60 to the lower surface 62 for absorption.

[0056] The above electronic cigarette atomizer forms an atomization chamber between the atomizing surface and the receiving seat. During the inhalation process, the airflow passes through the entire atomization chamber, thereby maximizing the outflow of aerosols within the atomization chamber with the airflow and reducing stagnation. Furthermore, the receiving seat can receive and guide the condensate to the lower surface for retention, thus effectively preventing the condensate from being drawn in or seeping out with the airflow.

[0057] It should be noted that the preferred embodiments of the present invention are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
