Chinese Patent Application No.2020109813116, filed on September 17, 2020 - The present disclosure relates to the field of an atomizer, and in particular to an electronic atomizing assembly and an electronic atomizing device.
- 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.
- The present application provides an electronic atomizing assembly and an electronic atomizing device to solve the problem of a leak of e-liquid when the user inhales an aerosol in the existing technology.
- According to an aspect of the present disclosure, an electronic atomizing assembly is provided. The assembly includes: a cartridge, a heating cover, and a heating base. The heating cover defines a first groove, and the first serves as an upper part of the atomizing chamber. A side wall of the first groove defines a receiving groove. The heating base defines a second groove. The second groove serves as a lower part of the atomizing chamber and is combined with an upper part of the atomizing chamber to compose the atomizing chamber. A side wall of the second groove is provided with a protrusion member, and the protrusion member is received in the receiving groove. The protrusion member and the receiving groove are cooperatively used to realize the sealing between the cartridge and the atomizing chamber.
- In some embodiments, the grooving direction of the receiving groove is the same as the grooving direction of the first groove, and the height direction of the protrusion member is the same as the grooving direction of the second groove.
- In some embodiments, the side walls of the first groove include a first side wall, a second side wall, a third side wall, and a fourth side wall. The first side wall is opposite to the third side wall, and the second side wall is opposite to the fourth side wall. The second side wall defines a first receiving groove, and the fourth side wall defines a second receiving groove. The side walls of the second groove include a fifth side wall, a sixth side wall, a seventh side wall, and an eighth side wall. The fifth side wall is opposite to the seventh side wall, and the sixth side wall is opposite to the eighth side wall. The sixth side wall is provided with a first protrusion member, and the eighth side wall is provided with a second protrusion member.
- In some embodiments, the first side wall defines a first notch, and the third side wall defines a second notch. One end of the first receiving groove extends to the first side wall and is close to the first notch, and the other end of the first receiving groove extends to the third side wall and is close to the second notch. One end of the second receiving groove extends to the first side wall and close to the first notch, and the other end extends of the second receiving groove to the third side wall and close to the second notch. The fifth side wall defines a third notch, and the seventh side wall defines a fourth notch. One end of the first protrusion member extends to the fifth side wall and is close to the third notch, and the other end of the first protrusion member extends to the seventh side wall and is close to the fourth notch. One end of the second protrusion member extends to the fifth side wall and is close to the third notch, and the other end of the second protrusion member extends to the seventh side wall is close to the fourth notch.
- In some embodiments, an inner side wall of the receiving grooves defines notches, and a side wall of the protrusion members is provided with projections, and the projections are arranged in cooperation with the recesses.
- In some embodiments, the material of the heating cover is plastic, and the material of the heating base is silica gel.
- In some embodiments, the bottom wall of the first groove defines a through-hole, and a side wall of the through-hole is provided with a bump or defines a third groove.
- In some embodiments, a plurality of bumps or a plurality of third grooves arranged at intervals is arranged on the side wall of the through-hole along the circumferential direction.
- In some embodiments, the cross-section of the bump or the third groove is square, triangular, or arc-shaped.
- In some embodiments, the electronic atomizing assembly further includes a suction tube, and the through-hole is communicated with the suction tube so that the atomizing chamber is communicated with the suction tube.
- According to another aspect of the present disclosure, an electronic atomizing device is provided and includes an electronic atomizing assembly and a power assembly. The electronic atomizing assembly is the electronic atomizing assembly described in any one of the above embodiments.
- The present disclosure realizes the sealing between the cartridge and the atomizing chamber by setting the receiving groove on the heating cover and the protrusion member on the heating base. By preventing e-liquid of the cartridge from permeating into the atomizing chamber, the performance of the atomizer is improved, and at the same time, the user is prevented from sucking the e-liquid to be atomized, which affects the experience of use.

- 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, andFIG. 2 is a cross-sectional view along the direction B-B. The direction A-A is perpendicular to the direction B-B. - The electronic atomizing assembly may include a
cartridge 10, aheating cover 20, aheating base 30, aheating coil 40, asuction tube 50, and amouthpiece 60. - The
cartridge 10 may be sleeved on theheating cover 20, and is configured to store e-liquid. Thecartridge 10 may be plastic, and can also be metal, such as aluminum and stainless steel. Thecartridge 10 only needs to be able to store e-liquid without making it deteriorated. The shape and size of thecartridge 10 are not limited and can be designed as required. - The
heating cover 20 and theheating base 30 define anatomizing chamber 70. Theheating coil 40 may be disposed between theheating cover 20 and theheating base 30. Theheating coil 40 is at least partially disposed in theatomizing chamber 70. Theheating cover 20 may cooperate with theheating base 30 to realize the seal between thecartridge 10 and theatomizing chamber 70. The material of theheating cover 20 is plastic, such as plastic PCTG (polyethylene terephthalate-1, 4-cyclohexanedimethanol). The material of theheating base 30 may be silica gel, such as 70-degree silica gel. The shape and size of theheating cover 20 and theheating base 30 are not limited and can be designed as required. - The
suction tube 50 penetrates thecartridge 10, and one end of thesuction tube 50 may be connected with themouthpiece 60, and the other end of the suction tube may be connected with theheating cover 20. Thesuction tube 50 may communicate with theatomizing chamber 70 through theheating cover 20. In this way, the atomized gas in theatomizing chamber 70 can be inhaled by the user through thesuction tube 50. - The sealing between the
cartridge 10 and theatomizing chamber 70 can prevent the e-liquid to be atomized from leaking from thecartridge 10 into theatomizing chamber 70. Since theatomizing chamber 70 is in communication with thesuction tube 50, by preventing the e-liquid to be atomized from leaking from thecartridge 10 into theatomizing chamber 70, the leak of e-liquid into thesuction tube 50 can be avoided. Hence, the phenomenon of a leak of e-liquid when the user inhales an aerosol is avoided. -
FIG. 3 is a structural schematic view of a heating cover of the electronic atomizing assembly of a first embodiment of the present disclosure, andFIG. 4 is a structural schematic view of a heating base of the electronic atomizing assembly of a first embodiment of the present disclosure. - As shown in
FIG. 3 , in a first embodiment, theheating cover 20 may define afirst groove 21, and thefirst groove 21 may form an upper part of theatomizing chamber 70. A side wall of thefirst groove 21 may define a receivinggroove 211, and a grooving direction of the receivinggroove 211 may be the same as the grooving direction of thefirst groove 21. In other words, a depth direction of the receivinggroove 211 is the same as a depth direction of thefirst groove 21. - Side walls of the
first groove 21 may include afirst side wall 212, asecond side wall 213, athird side wall 214, and afourth side wall 215. Thefirst side wall 212 and thethird side wall 214 are opposite to each other, and thesecond side wall 213 and thefourth side wall 215 are opposite to each other. Thefirst side wall 212 defines afirst notch 2121, and thethird side wall 214 defines asecond notch 2141. The shape and size of thefirst notch 2121 and thesecond notch 2141 are the same. Thefirst notch 2121 and thesecond notch 2141 are the lower liquid ventilation ports of theelectronic atomizing assembly 1. Thesecond side wall 213 may define afirst receiving groove 2111, and thefourth side wall 215 may define asecond receiving groove 2112. One end of thefirst receiving groove 2111 disposed on thesecond side wall 213 extends to a part of thefirst side wall 212 and is close to thefirst notch 2121. The other end of thefirst receiving groove 2111 extends to a part of thethird side wall 214 and is close to thesecond notch 2141. - In a specific embodiment, only the receiving
groove 211 is disposed on thesecond side wall 213, or only the receivinggroove 211 is disposed on thefourth side wall 215. In some embodiments, thefirst receiving groove 2111 is disposed on thesecond side wall 213, and thesecond receiving groove 2112 is disposed on thefourth side wall 215. Thefirst receiving groove 2111 and thesecond receiving groove 2112 may be continuous or discontinuous. In some embodiments, thefirst receiving groove 2111 and thesecond receiving groove 2112 are both continuous. - Ends of the
first receiving groove 2111 and thesecond receiving groove 2112 close to thefirst notch 2121 or thesecond notch 2141 may be closed-ends, and may not be communicated with thefirst notch 2121 or thesecond notch 2141. In other words, the ends of thefirst receiving groove 2111 and thesecond receiving groove 2112 close to thefirst notch 2121 or thesecond notch 2141 are blocked by side walls of thefirst notch 2121 or thesecond notch 2141. Heights of two opposite side walls of thefirst receiving groove 2111 may be the same or different, and heights of two opposite side walls of thesecond receiving groove 2112 may be the same or different. In one embodiment, the side walls of thefirst receiving groove 2111 and thesecond receiving groove 2112 close to theatomizing chamber 70 are lower than the side walls of thefirst receiving groove 2111 and thesecond receiving groove 2112 far from the atomizingchamber 70. In other words, inner side walls of thefirst receiving groove 2111 and thesecond receiving groove 2112 are lower than outer side walls, which could facilitate the installation on aprotrusion member 311 of theheating base 30 and allow theatomizing chamber 70 to have a larger space. Cross-sections of thefirst receiving groove 2111 and thesecond 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 receivinggroove 211 and theprotrusion member 311 and a good seal. The depths of thefirst receiving groove 2111 and thesecond 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 theprotrusion member 311, realizing the sealing between the atomizingchamber 70 and thecartridge 10. - In the first embodiment, as shown in
FIG. 4 , theheating base 30 may define asecond groove 31. Thesecond groove 31 may form the lower part of theatomizing chamber 70 and configure to thefirst groove 21 to form theatomizing chamber 70. Theprotrusion member 311 is disposed on side walls of thesecond groove 31, and the height direction of the strip-shapedprotrusion 311 is the same as an extension direction of the side wall of thesecond groove 31. - The side walls of the
second groove 31 may include afifth side wall 312, asixth side wall 313, aseventh side wall 314, and aneighth side wall 315. Thefifth side wall 312 and theseventh side wall 314 are opposite to each other, and thesixth side wall 313 and theeighth side wall 315 are opposite to each other. Thefifth side wall 312 defines athird notch 3121, and theseventh side wall 314 defines afourth notch 3141. The shape and size of thethird notch 3121 and thefourth notch 3141 are the same. One end of theheating coil 40 is lapped on thethird notch 3121 of theheating base 30, and the other end of the heating coil is lapped on thefourth notch 3141 so that the middle part of theheating coil 40 is suspended in theatomizing chamber 70. Afirst protrusion member 3111 is disposed on thesixth side wall 313, and asecond protrusion member 3112 is disposed on theeighth side wall 315. One end of theprotrusion member 3111 disposed on thesixth side wall 313 extends to a part of thefifth side wall 312 and is close to thethird notch 3121; the other end of the protrusion member extends to a part of theseventh side wall 314 and is close to thefourth notch 3141. One end of thesecond protrusion member 3112 disposed on theeighth side wall 315 extends to a part of thefifth side wall 312 and is close to thethird notch 3121; the other end of the second protrusion member extends to a part of theseventh side wall 314 and is close to thefourth notch 3141. - In a specific embodiment, the
protrusion member 311 may be disposed only on thesixth side wall 313, or only theprotrusion member 311 may be disposed on theeighth side wall 315. In some embodiments, thefirst protrusion member 3111 is disposed on thesixth side wall 313, and thesecond protrusion member 3112 is disposed on theeighth side wall 315. Thefirst protrusion member 3111 and thesecond protrusion member 3112 can be continuous or discontinuous. In some embodiments, both thefirst protrusion member 3111 and thesecond protrusion member 3112 are continuous. - End faces of the
first protrusion member 3111 and thesecond protrusion member 3112 close to thethird notch 3121 or thefourth notch 3141 are coplanar with side surfaces of thethird notch 3121 or thefourth notch 3141, and are inclined to thefirst protrusion member 3111 or the second protrusion member. Cross-sections of thefirst protrusion member 3111 and thesecond 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 receivinggroove 211 and theprotrusion member 311 and a good seal. The height and cross-sectional shape of thefirst protrusion member 3111 and thesecond protrusion member 3112 can be designed as requirements, as long as the sealing between the atomizingchamber 70 and thecartridge 10 can be achieved by cooperation between theprotrusion member 311 and the receivinggroove 211. -
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. - After the
heating cover 20 and theheating base 30 are assembled together, thefirst notch 2121 on theheating cover 20 corresponds to thethird notch 3121 on theheating base 30, thesecond notch 2141 on theheating cover 20 corresponds to thefourth notch 3141 on theheating base 30. The structural size of theprotrusion member 311 defined on the side wall of thesecond groove 31 is matched with the structural size of the receivinggroove 211 defined on the side wall of thefirst groove 21 to achieve a good seal. - In a specific embodiment, the
first receiving groove 2111 is continuous. Thesecond receiving groove 2112 is discontinuous. In other words, thesecond receiving groove 2112 includes multiplesub-receiving grooves 211. The size among thesub-receiving grooves 211 may be the same or different, and in some embodiments, the size among thesub-receiving grooves 211 is the same. The depth of thesecond receiving groove 2112 is greater than the depth of thefirst receiving groove 2111. In this situation, thefirst protrusion member 3111 is continuous, and thesecond protrusion member 3112 is discontinuous. That is, thesecond protrusion member 3112 includes a plurality ofsub-protrusion member 311. The structural dimensions of the plurality ofsub-protrusive protrusions 311 may be the same or different. In some embodiment, the structural dimensions of the sub-protrusion member 311 are the same. The height of thesecond protrusion member 3112 is greater than the height of thefirst protrusion member 3111. The structure and size of the receivinggroove 211 and theprotrusion member 311 are matched, and the number of thesub-receiving groove 211 and the number of thesub-protrusion member 311 are the same. When the receivinggroove 211 and theprotrusion member 311 are arranged in multiple sections, the depth of the receivinggroove 211 can be increased appropriately, and the height of theprotrusion member 311 can be increased accordingly to achieve a better sealing effect. In some embodiments, the receivinggroove 211 and theprotrusion member 311 are arranged to be continuous. Compared with the multiplesub-receiving grooves 211 and the multiple sub-protrusion member 311, a better sealing effect can be achieved, andcartridge 10 can be prevented to the greatest extent from leaking to theatomizing chamber 70. - In other embodiments, the side wall of the
first groove 21 of theheating cover 20 is provided with theprotrusion member 311, and the height direction of theprotrusion member 311 is opposite to the depth direction of thefirst groove 21. The side wall of thesecond groove 31 of theheating base 30 defines the receivinggroove 211, and the depth direction of the receivinggroove 211 is the same as the depth direction of thesecond groove 31. The structural dimensions of the receivinggroove 211 and theprotrusion member 311 are matched. -
FIG. 6 is a structural schematic view of a through-hole of the heating cover of the electronic atomizing assembly. - The bottom wall of the
first groove 21 defines a through-hole 216, and thesuction tube 50 communicates with theatomizing chamber 70 through the through-hole 216 so that the atomized gas in theatomizing chamber 70 can be inhaled by the user through thesuction tube 50. A plurality ofbumps 2161 are disposed on a side wall of the through-hole 216, and the thickness of thebumps 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 thebumps 2161 is smaller than the depth of the through-hole 216, one surface of thebumps 2161 and one end surface of the through-hole 216 are in a same plane, or thebump 2161 is disposed at the middle position of a side wall of the through-hole 216. - 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 ofbumps 2161 may be equal or unequal, in some embodiments being equal. Thebumps 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 thebump 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 ofbumps 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 ofbumps 2161, or the cross-sectional shape and size of the plurality ofbumps 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. - By arranging a plurality of
