ELECTRONIC ATOMIZATION ARRANGEMENT AND DEVICE

Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of an atomizer, and in particular to an electronic atomizing assembly and an electronic atomizing device.BACKGROUND

[0002] In the existing electronic atomizing device, a leak of e-liquid when the user inhales an aerosol is a common pain point in the industry. One of the main reasons for the leak is insufficient sealing of the atomizing chamber. This causes the e-liquid in the cartridge to permeate into the atomizing chamber during suction, and the e-liquid is drawn into the central tube, resulting in a phenomenon of the leak. Another reason for the leak is that the condensate of the cigarette gas forms an oil film in the central tube. The oil film is difficult to break and is easily sucked into the mouth of users during suction. Such electronic atomizing devices are known, e.g. from CN 206 062 138 U, CN 110 292 211 A, US 2019 / 364972 A1, WO 2019 / 137561 A1, EP 3 622 838 A2 or WO 2020 / 176901 A2.SUMMARY OF THE DISCLOSURE

[0016] The technical solutions in the embodiments of the present disclosure will be clearly and completely described by referring to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of, but not all of, the embodiments of the present disclosure.

[0017] The terms "first", "second" and "third" in the embodiments of the present disclosure are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance of the indicated technical features or implicitly specifying the number of the technical features. Therefore, a feature defined by the "first," "second," or "third" may explicitly or implicitly include at least one such feature. In the description of the present disclosure, "plurality" means at least two, such as two, three, etc., unless otherwise expressively and specifically limited. In addition, the terms "includes" and "has", and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, a method, a system, a product or an apparatus including a series of operations or units is not limited to the listed operations or units, but optionally also includes operations or units that are not listed, or optionally also includes other operations or units that are inherent to the process, the method, the product or the apparatus.

[0018] References to "embodiments" mean that a particular feature, structure, or characteristic described by referring to an embodiment may be included in at least one embodiment of the present disclosure. The presence of the term at various sections in the specification does not necessarily mean a same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. It is understood, both explicitly and implicitly, by the skilled person in the art that the embodiments described herein may be combined with other embodiments.

[0019] The present disclosure provides an electronic atomizing assembly, shown in FIG. 1 and FIG. 2. FIG. 1 is a cross-sectional view along the direction A-A of the electronic atomizing assembly, and FIG. 2 is a cross-sectional view along the direction B-B. The direction A-A is perpendicular to the direction B-B.

[0020] The electronic atomizing assembly may include a cartridge 10, a heating cover 20, a heating base 30, a heating coil 40, a suction tube 50, and a mouthpiece 60.

[0021] The cartridge 10 may be sleeved on the heating cover 20, and is configured to store e-liquid. That is, the heating cover 20 is arranged in the cartridge 10. The cartridge 10 may be plastic, and can also be metal, such as aluminum and stainless steel. The cartridge 10 only needs to be able to store e-liquid without making it deteriorated. The shape and size of the cartridge 10 are not limited and can be designed as required.

[0022] The heating cover 20 and the heating base 30 define an atomizing chamber 70. The heating coil 40 may be disposed between the heating cover 20 and the heating base 30. The heating coil 40 is at least partially disposed in the atomizing chamber 70. The heating cover 20 may cooperate with the heating base 30 to realize the seal between the cartridge 10 and the atomizing chamber 70. The material of the heating cover 20 is plastic, such as plastic PCTG (polyethylene terephthalate-1, 4-cyclohexanedimethanol). The material of the heating base 30 may be silica gel, such as 70-degree silica gel. The shape and size of the heating cover 20 and the heating base 30 are not limited and can be designed as required.

[0023] The suction tube 50 penetrates the cartridge 10, and one end of the suction tube 50 may be connected with the mouthpiece 60, and the other end of the suction tube may be connected with the heating cover 20. The suction tube 50 may communicate with the atomizing chamber 70 through the heating cover 20. In this way, the atomized gas in the atomizing chamber 70 can be inhaled by the user through the suction tube 50.

[0024] The sealing between the cartridge 10 and the atomizing chamber 70 can prevent the e-liquid to be atomized from leaking from the cartridge 10 into the atomizing chamber 70. Since the atomizing chamber 70 is in communication with the suction tube 50, by preventing the e-liquid to be atomized from leaking from the cartridge 10 into the atomizing chamber 70, the leak of e-liquid into the suction tube 50 can be avoided. Hence, the phenomenon of a leak of e-liquid when the user inhales an aerosol is avoided.

[0025] FIG. 3 is a structural schematic view of a heating cover of the electronic atomizing assembly of a first embodiment of the present disclosure, and FIG. 4 is a structural schematic view of a heating base of the electronic atomizing assembly of a first embodiment of the present disclosure.

[0026] As shown in FIG. 3, in a first embodiment, the heating cover 20 may define a first groove 21, and the first groove 21 may form an upper part of the atomizing chamber 70. A side wall of the first groove 21 may define a receiving groove 211, and a grooving direction of the receiving groove 211 may be the same as the grooving direction of the first groove 21. In other words, a depth direction of the receiving groove 211 is the same as a depth direction of the first groove 21.

[0027] Side walls of the first groove 21 may include a first side wall 212, a second side wall 213, a third side wall 214, and a fourth side wall 215. The first side wall 212 and the third side wall 214 are opposite to each other, and the second side wall 213 and the fourth side wall 215 are opposite to each other. The first side wall 212 defines a first notch 2121, and the third side wall 214 defines a second notch 2141. The shape and size of the first notch 2121 and the second notch 2141 are the same. The first notch 2121 and the second notch 2141 are the lower liquid ventilation ports of the electronic atomizing assembly 1. The receiving groove 211 may include a first receiving groove 2111 and a second receiving groove 2112. The second side wall 213 may define the first receiving groove 2111, and the fourth side wall 215 may define the second receiving groove 2112. One end of the first receiving groove 2111 disposed on the second side wall 213 extends to a part of the first side wall 212 and is close to the first notch 2121. The other end of the first receiving groove 2111 extends to a part of the third side wall 214 and is close to the second notch 2141.

[0028] In a specific embodiment, only the receiving groove 211 is disposed on the second side wall 213, or only the receiving groove 211 is disposed on the fourth side wall 215. In some embodiments, the first receiving groove 2111 is disposed on the second side wall 213, and the second receiving groove 2112 is disposed on the fourth side wall 215. The first receiving groove 2111 and the second receiving groove 2112 may be continuous or discontinuous. In some embodiments, the first receiving groove 2111 and the second receiving groove 2112 are both continuous.

[0029] Ends of the first receiving groove 2111 and the second receiving groove 2112 close to the first notch 2121 or the second notch 2141 may be closed-ends, and may not be communicated with the first notch 2121 or the second notch 2141. In other words, the ends of the first receiving groove 2111 and the second receiving groove 2112 close to the first notch 2121 or the second notch 2141 are blocked by side walls of the first notch 2121 or the second notch 2141. Heights of two opposite side walls of the first receiving groove 2111 may be the same or different, and heights of two opposite side walls of the second receiving groove 2112 may be the same or different. In one embodiment, the side walls of the first receiving groove 2111 and the second receiving groove 2112 close to the atomizing chamber 70 are lower than the side walls of the first receiving groove 2111 and the second receiving groove 2112 far from the atomizing chamber 70. In other words, inner side walls of the first receiving groove 2111 and the second receiving groove 2112 are lower than outer side walls, which could facilitate the installation on a protrusion member 311 of the heating base 30 and allow the atomizing chamber 70 to have a larger space. Cross-sections of the first receiving groove 2111 and the second receiving groove 2112 are trapezoidal, and the upper part is wide, and the lower part is narrow, and edges and corners are set to arc surfaces, which could facilitate the assembly of the receiving groove 211 and the protrusion member 311 and a good seal. The upper part refers to a top of the first receiving groove 2111 or the second receiving groove 2112, and the lower part refers to a bottom of the first receiving groove 2111 or the second receiving groove 2112, the top of the first receiving groove 2111 is wider than the bottom of the first receiving groove 2111; the top of the second receiving groove 2112 is wider than the bottom of the second receiving groove 2112. The depths of the first receiving groove 2111 and the second receiving groove 2112, the heights of the two opposite side walls, and the cross-sectional shape can be designed according to requirements, as long as the design could cooperate with the protrusion member 311, realizing the sealing between the atomizing chamber 70 and the cartridge 10.

[0030] In the first embodiment, as shown in FIG. 4, the heating base 30 may define a second groove 31. The second groove 31 may form the lower part of the atomizing chamber 70 and configure to the first groove 21 to form the atomizing chamber 70. The protrusion member 311 is disposed on side walls of the second groove 31, and the height direction of the strip-shaped protrusion 311 is the same as an extension direction of the side wall of the second groove 31.

[0031] The side walls of the second groove 31 may include a fifth side wall 312, a sixth side wall 313, a seventh side wall 314, and an eighth side wall 315. The fifth side wall 312 and the seventh side wall 314 are opposite to each other, and the sixth side wall 313 and the eighth side wall 315 are opposite to each other. The fifth side wall 312 defines a third notch 3121, and the seventh side wall 314 defines a fourth notch 3141. The shape and size of the third notch 3121 and the fourth notch 3141 are the same. One end of the heating coil 40 is lapped on the third notch 3121 of the heating base 30, and the other end of the heating coil is lapped on the fourth notch 3141 so that the middle part of the heating coil 40 is suspended in the atomizing chamber 70. The protrusion member 311 includes a first protrusion member 3111 and a second protrusion member 3112. The first protrusion member 3111 is disposed on the sixth side wall 313, and the second protrusion member 3112 is disposed on the eighth side wall 315. One end of the protrusion member 3111 disposed on the sixth side wall 313 extends to a part of the fifth side wall 312 and is close to the third notch 3121; the other end of the protrusion member extends to a part of the seventh side wall 314 and is close to the fourth notch 3141. One end of the second protrusion member 3112 disposed on the eighth side wall 315 extends to a part of the fifth side wall 312 and is close to the third notch 3121; the other end of the second protrusion member extends to a part of the seventh side wall 314 and is close to the fourth notch 3141.

[0032] In a specific embodiment, the protrusion member 311 may be disposed only on the sixth side wall 313, or only the protrusion member 311 may be disposed on the eighth side wall 315. In some embodiments, the first protrusion member 3111 is disposed on the sixth side wall 313, and the second protrusion member 3112 is disposed on the eighth side wall 315. The first protrusion member 3111 and the second protrusion member 3112 can be continuous or discontinuous. In some embodiments, both the first protrusion member 3111 and the second protrusion member 3112 are continuous.

[0033] End faces of the first protrusion member 3111 close to the third notch 3121 or the fourth notch 3141 are coplanar with side surfaces of the third notch 3121 or the fourth notch 3141, and are inclined to the first protrusion member 3111. End faces of the second protrusion member 3112 close to the third notch 3121 or the fourth notch 3141 are coplanar with side surfaces of the third notch 3121 or the fourth notch 3141 and are inclined to the second protrusion member 3112. Cross-sections of the first protrusion member 3111 and the second protrusion member 3112 are trapezoidal, and the upper part is narrow and the lower part is wide, and the edges and corners are set to arc surfaces, which could facilitate the assembly of the receiving groove 211 and the protrusion member 311 and a good seal. The lower part refers to the part of the first protrusion member 3111 close to the sixth side wall 313, and the part of the second protrusion member 3112 close to the eighth side wall 315; the upper part refers to the part of the first protrusion member 3111away from the sixth side wall 313, and the part of the second protrusion member 3112 away from the eighth side wall 315; the part of the first protrusion member 3111 close to the sixth side wall 313 is wider than the part of the first protrusion member 3111 away from the sixth side wall 313; the part of the second protrusion member 3112 close to the eighth side wall 315 is wider than the part of the second protrusion member 3112 away from the eighth side wall 315. The height and cross-sectional shape of the first protrusion member 3111 and the second protrusion member 3112 can be designed as requirements, as long as the sealing between the atomizing chamber 70 and the cartridge 10 can be achieved by cooperation between the protrusion member 311 and the receiving groove 211.

[0034] FIG. 5 is a structural schematic view of the configuration of the heating cover and the heating base of the electronic atomizing assembly of the present disclosure.

[0035] After the heating cover 20 and the heating base 30 are assembled together, the first notch 2121 on the heating cover 20 corresponds to the third notch 3121 on the heating base 30, the second notch 2141 on the heating cover 20 corresponds to the fourth notch 3141 on the heating base 30. The structural size of the protrusion member 311 defined on the side wall of the second groove 31 is matched with the structural size of the receiving groove 211 defined on the side wall of the first groove 21 to achieve a good seal.

[0036] In a specific embodiment, the first receiving groove 2111 is continuous. The second receiving groove 2112 is discontinuous. In other words, the second receiving groove 2112 includes multiple sub-receiving grooves. The size among the sub-receiving grooves may be the same or different, and in some embodiments, the size among the sub-receiving grooves is the same. The depth of the second receiving groove 2112 is greater than the depth of the first receiving groove 2111. In this situation, the first protrusion member 3111 is continuous, and the second protrusion member 3112 is discontinuous. That is, the second protrusion member 3112 includes a plurality of sub-protrusion member. The structural dimensions of the plurality of sub-protrusive protrusions 311 may be the same or different. In some embodiment, the structural dimensions of the sub-protrusion member are the same. The height of the second protrusion member 3112 is greater than the height of the first protrusion member 3111. The structure and size of the receiving groove 211 and the protrusion member 311 are matched, and the number of the sub-receiving groove and the number of the sub-protrusion member are the same. When the receiving groove 211 and the protrusion member 311 are arranged in multiple sections, the depth of the receiving groove 211 can be increased appropriately, and the height of the protrusion member 311 can be increased accordingly to achieve a better sealing effect. In some embodiments, the receiving groove 211 and the protrusion member 311 are arranged to be continuous. Compared with the multiple sub-receiving grooves and the multiple sub- protrusion member 311, a better sealing effect can be achieved, and cartridge 10 can be prevented to the greatest extent from leaking to the atomizing chamber 70.

[0037] In other embodiments, the side wall of the first groove 21 of the heating cover 20 is provided with the protrusion member 311, and the height direction of the protrusion member 311 is opposite to the depth direction of the first groove 21. The side wall of the second groove 31 of the heating base 30 defines the receiving groove 211, and the depth direction of the receiving groove 211 is the same as the depth direction of the second groove 31. The structural dimensions of the receiving groove 211 and the protrusion member 311 are matched.

[0038] FIG. 6 is a structural schematic view of a through-hole of the heating cover of the electronic atomizing assembly.

[0039] The bottom wall of the first groove 21 defines a through-hole 216, and the suction tube 50 communicates with the atomizing chamber 70 through the through-hole 216 so that the atomized gas in the atomizing chamber 70 can be inhaled by the user through the suction tube 50. A plurality of bumps 2161 are disposed on a side wall of the through-hole 216, and the thickness of the bumps 2161 and the depth of the through-hole 216 can be the same or different, in some embodiments being the same. When the thickness of the bumps 2161 is smaller than the depth of the through-hole 216, one surface of the bumps 2161 and one end surface of bottom wall around the through-hole 216 are in a same plane, or the bump 2161 is disposed at the middle position of a side wall of the through-hole 216.

[0040] The plurality of bumps 2161 are arranged at intervals along the circumferential direction of the side wall of the through-hole 216, and the interval between the plurality of bumps 2161 may be equal or unequal, in some embodiments being equal. The bumps 2161 may be disposed on the entire circumference of the side wall of the through-hole 216 or may be disposed on a certain section of the side wall of the through-hole 216. The cross-section of the bump 2161 may be square, triangle, arc, or other shapes, and only needs to make the side wall of the through-hole 216 uneven. The cross-sectional shape and size of the plurality of bumps 2161 can be the same or different, and only the side wall of the through-hole 216 needs to be uneven. A certain section of the side wall of the through-hole 216 is provided with the plurality of bumps 2161, or the cross-sectional shape and size of the plurality of bumps 2161 are different so that the through-hole 216 defines an asymmetric structure, which makes the liquid film easier to break, in some embodiments being the asymmetric structure.

[0041] By arranging a plurality of bumps 2161 on the side wall of the through-hole 216, the side wall of the through-hole 216 is uneven, which avoids the formation of a liquid film at the through-hole 216 after the accumulation of condensate during the use of the atomizer, and prevents the phenomenon of the leak, and the performance of the atomizer is improved.

[0042] FIG. 7 is a structural schematic view of a through-hole of the heating cover of the electronic atomizing assembly of another embodiment of the present disclosure.

[0043] In another embodiment, the side wall of the through-hole 216 defines a plurality of grooves 2162. At the opposite ends of the groove 2162 in the depth direction of the through-hole 216, one of the grooves 2162 may be an open-end and the other may be a closed-end, or both open-end or closed-end, in some embodiments being both open-ends of the groove 2162.

[0044] The plurality of grooves 2162 are arranged at intervals along the circumferential direction of the side wall of the through-hole 216, and the interval between the plurality of grooves 2162 may be equal or unequal, in some embodiments being equal. The groove 2162 may be defined on the entire circumference of the side wall of the through-hole 216 or may be defined on a certain section of the side wall of the through-hole 216. The cross-section of the groove 2162 may be square, triangle, arc, or other shapes, and only needs to make the side wall of the through-hole 216 uneven. The cross-sectional shape and size of the plurality of grooves 2162 may be the same or different, as long as the side wall of the through-hole 216 is uneven. A certain section of the side wall of the through-hole 216 defines multiple grooves 2162, or the cross-sectional shape and size of the multiple grooves 2162 are different so that the through-hole 216 defines an asymmetric structure, making the liquid film easier to rupture. In some embodiments, the plurality of grooves 2162 defines an asymmetric structure in the circumferential direction of the side wall of the through-hole 216.

[0045] By providing a plurality of grooves 2162 on the side wall of the through-hole 216, the side wall of the through-hole 216 is uneven, which avoids the formation of a liquid film at the through-hole 216 after the accumulation of condensate during the use of the atomizer, and prevents the phenomenon of the leak, and the performance of the atomizer is improved.

[0046] FIG. 8 is a cross-sectional view of the configuration of a receiving groove on the heating cover and protrusion members on the heating base of the electronic atomizing assembly.

[0047] Compared with the first embodiment of the second embodiment of the electronic atomizing assembly 1, the structure of the electronic atomizing assembly 1 is basically the same, and the difference lies in the structure of the receiving groove 211 on the heating cover 20 and the structure the protrusion member 311 on the heating base 30.

[0048] In the second embodiment, the heating cover 20 defines a first groove 21, and the first groove 21 serves as the upper part of the atomizing chamber 70. The side wall of the first groove 21 defines the receiving groove 211, and the grooving direction of the receiving groove 211 is the same as that of the first groove 21. That is, the depth direction of the receiving groove 211 is the same as that of the first groove 211. The depth directions of the grooves 21 are the same. An inner side wall of the receiving groove 211 defines a recess 2113. The receiving groove 211 has two opposite inner side walls in a direction perpendicular to the extending direction. Both the two opposite inner side walls may define a recess 2113, or only one of the inner side walls may define the recess 2113. In some embodiments, both the two opposite inner side walls of the receiving groove 211 define the recess 2113. The depth direction of the recess 2113 is perpendicular to the depth direction of the receiving groove 211.

[0049] Side walls of the first groove 21 may include a first side wall 212, a second side wall 213, a third side wall 214, and a fourth side wall 215. The first side wall 212 and the third side wall 214 are oppositely arranged, and the second side wall 213 and the fourth side wall 215 are oppositely arranged. The first side wall 212 defines a first notch 2121, the third side wall 214 defines a second notch 2141, and the shape and size of the first notch 2121 and the second notch 2141 are the same.
