The present disclosure provides an atomizer, which is applied to an electronic cigarette product that heats and atomizes liquid. Generally, a tabular atomizer is taken as example to illustrate in one embodiment.
Referring to FIG. 1 to FIG. 4, which show a structure assembly diagram, a sectional view and an exploded view of an atomizer according to one embodiment, the overall appearance generally presents a tabular shape, including a length direction, a width direction and a thickness direction that are perpendicular to each other in a three-dimensional space and are expressed respectively as L direction, W direction and T direction indicated by a coordinate in FIG. 1 and FIG. 2. The atomizer for electronic cigarette has a greater size along the length direction L than the width direction W, and has a greater size along the width direction W than the thickness direction T. Based on commonly used requirements, two ends of the atomizer along the length direction L are configured as a proximal end 110 and a distal end 120 respectively, wherein the proximal end 110 is configured as one end for installing a mouthpiece cap and inhaling an aerosol, and the distal end 120 is configured as one end of the atomizer to assemble and connect with a power part of the electronic cigarette. In terms of specific components, the atomizer includes:
a hollow tubular outer shell 10 extending along the length direction L of the atomizer; based on different usages, the proximal end 110 of the outer shell 10 is a closed end, on which a smoking port A is defined for a user to suck; the distal end 120 of the outer shell 10 is designed as an opening, on which a detachable end cover 20 is installed, wherein the opening structure of the distal end 120 is used for installing various necessary functional parts inside the outer shell 10. To facilitate the following description and reader's appreciation of the difference in direction(s), referring to FIG. 1 to FIG. 3, the outer shell 10 includes a first side wall 130 and a second side wall 140 that are opposite to each other in the thickness direction T.
Further, the outer shell 10 is internally provided with an liquid storage cavity 30 configured for storing liquid and an atomizing assembly 40 configured for absorbing the liquid from the liquid storage cavity 30 to heat and atomize; specifically,
in the sectional structure diagrams shown in FIG. 5 and FIG. 6, a smoke conveying pipe 11 is arranged inside the outer shell 10 along the axial direction, wherein a space between an outer wall of the smoke conveying pipe 11 and an inner wall of the outer shell 10 forms the liquid storage cavity 30 configured for storing an liquid.
The atomizing assembly 40 is arranged between the liquid storage cavity 30 and the end cover 20; referring to FIG. 3, the structure of the atomizing assembly 40 may include a porous body 41 configured for absorbing the liquid from the liquid storage cavity 30, and a heating body 42 configured for heating and atomizing the liquid absorbed into the porous body 41. As shown in FIG. 3 to FIG. 6, the porous body 41 in the embodiment may roughly present, but not limited to, a block shaped structure; according to the usage condition, the porous body includes a first side part 413 opposite to the first side wall 130 and a second side part 414 opposite to the second side wall 140, and a liquid absorption surface 411 and an atomizing surface 412 opposite to each other along the axial direction of the outer shell 10, that is, the upper and lower surfaces of the block-shaped porous body 41 shown in FIG. 3, wherein the liquid absorption surface 411 is opposite to the liquid storage cavity 30, directly or indirectly contacting the liquid in the liquid storage cavity 30 so as to absorb the liquid; the pores in the porous body 41 then transfer the liquid to the atomizing surface 412 to be heated and atomized to an aerosol, which then escapes from the atomizing surface 412. A space between the atomizing surface 412 and the end cover 20 forms an atomizing cavity 60 for the aerosol to escape and mix with air.
In the structure of the porous body 41 shown in FIG. 3, since the liquid absorption surface 411 and the atomizing surface 412 are parallel, the movement direction of both the liquid and the aerosol in the porous body 41 is perpendicular to the plane on which the atomizing surface 412 is located. Thus, the liquid and the aerosol move more smoothly in the porous body 41 and the manufacture is convenient. In some embodiments, the porous body 41 may be made of rigid capillary structures such as porous ceramic, porous glass ceramic and porous glass. The heating body 42 is preferably formed on the atomizing surface 412 by mixing a conductive raw material powder with a printing aid into a slurry and sintering the slurry after the slurry is printed, such that all or most of its surface is tightly combined with the atomizing surface 412. The heating body 42 achieves effects such as high efficiency of atomization, reduction of heat loss, prevention of dry burning or great reduction of dry burning. The heating body 42 may be made of materials such as stainless steel, nickel chromium alloy, iron chromium aluminum alloy and metal titanium in some embodiments.
Further, referring to FIG. 3 to FIG. 6, in order to install and fix the atomizing assembly 40 and seal the liquid storage cavity 30, a sealing assembly 50 is further arranged inside the outer shell 10, wherein the sealing assembly 50 includes a silicone sleeve 51, a support sleeve 52 and a silicone seat 53, which not only seals the port of the liquid storage cavity 30, but also fixedly holds the atomizing assembly 40 inside.
The silicone seat 53 is arranged on an end part of the liquid storage cavity 30 facing the distal end 120, with the appearance mated to the cross section of the inner outline of the outer shell 10, for sealing the liquid storage cavity 30 and preventing the liquid leaking from the liquid storage cavity 30. Further, in order to prevent the flexible silicone seat 53 shrinking and deforming to affect the tightness of sealing, a rigid support sleeve 52 is arranged inside the silicone seat 53; the rigid material padding prevents the silicone seat 53 shrinking and deforming, thereby ensuring the silicone seat 53 to tightly seal the liquid storage cavity 30. Meanwhile, in order to prevent the atomizing assembly 40 being directly held inside the rigid support sleeve 52 to result in untight joining and gaps and cause problems such as liquid leaking, a flexible silicone sleeve 51 is sleeved outside the atomizing assembly 40 before the atomizing assembly 40 is arranged inside the support sleeve 52.
The specific structure and shape can refer to FIG. 3 and FIG. 4, the silicone sleeve 51 roughly presents a tubular sleeve, of which the inner space is configured for accommodating the atomizing assembly 40 and which is sleeved outside the atomizing assembly 40 through a flexible tight fit mode.
The support sleeve 52 in some embodiments may include a main body 521 roughly presenting an elliptic cylinder shape, and an annular part 522 extending from the main body 521 towards the distal end 120, wherein the space inside the annular part 522 forms a holding cavity 523 configured for accommodating the silicone sleeve 51 and the atomizing assembly 40. The main body 521 defines thereon two first liquid guide holes 5211 and one gas guide hole 5212.
Further, the main body 521 defines thereon a first gas channel 5213 communicated with the gas guide hole 5212, wherein one end of the first gas channel 5213 runs through the main body to communicate with the gas guide hole 5212, while the other end is on a surface of the main body 521 opposite to the first side wall 130.
In order for the generated aerosol to smoothly enter the first gas channel 5213 after the atomizing assembly 40 is wrapped by the silicone sleeve 51, the silicone sleeve 51 defines a notch 511 at a position opposite to the first gas channel 5213; after the silicone sleeve 51 is assembled with the support sleeve 52, the notch 511 is communicated with the first gas channel 5213, thereby outputting the aerosol in the holding cavity 523 generated by the atomizing assembly 40 to the first gas channel 5213 through the notch 511.
The silicone seat 53 includes two opposite clamping walls 531 extending downwards from a bottom surface, and between the two clamping walls 531 is formed an accommodating cavity 532 configured for accommodating the main body 521 of the support sleeve 52. Meanwhile, the silicone seat 53 defines thereon two second liquid guide holes 533 and an insert hole 534 for the smoke conveying pipe 11 to insert into; wherein the two second liquid guide holes 533 correspond to the two first liquid guide holes 5211 on the support sleeve 52, and the insert hole 534 corresponds to the gas guide hole 5212 on the support sleeve 52. Moreover, the two second liquid guide holes 533 face the liquid storage cavity 30 and communicate with the liquid storage cavity to transfer the liquid; the insert hole 534 is connected to the smoke conveying pipe 11. In the preferred mode shown in FIG. 5, a first end of the smoke conveying pipe 11 opposite to the proximal end 110 is communicated with the smoking port A, and a second end opposite to the distal end 120 has the lower end directly inserted into the insert hole 534 to form an airflow channel.
Referring to FIG. 5, after the sealing assembly 50 is assembled, the two second liquid guide holes 533 on the silicone seat 53 are communicated with the two first liquid guide holes 5211 on the support sleeve 52, to form a complete liquid conveying channel; specifically, the transfer of the liquid can refer to an arrow R1 shown in FIG. 5, that is, flowing onto the liquid absorption surface 411 of the porous body 41 from the liquid storage cavity through the second liquid guide holes 533 and the first liquid guide holes 5211 in sequence, and then getting transferred inside the porous body 41 to the atomizing surface 412 to be atomized. The transfer process of the aerosol can refer to an arrow R2 shown in FIG. 3 to FIG. 7, that is, the aerosol escaping from the atomizing surface 412 passes through in sequence the notch 511 of the silicone sleeve 51, the first gas channel 5213 of the support sleeve 52, the gas guide hole 5212 and the insert hole 534, to finally enter the smoke conveying pipe 11 until the smoking port A where it is inhaled, thus a complete aerosol output channel is formed.
Referring to FIG. 3 to FIG. 6, the end cover 20 is configured for covering the distal end 120 of the outer shell 10, so as to form a closed internal space with the outer shell. The end cover 20 includes a cover body 21, a first support arm 22 standing on a top surface of the cover body 21, and a second support arm 23 standing on the top surface of the cover body 21 opposite to the first support arm 22, the first support arm 22 and the second support arm 23 are configured for supporting and fixing the sealing assembly 50. Meanwhile, after installed, the atomizing assembly 40 is located between the first support arm 22 and the second support arm 23, such that the atomizing surface 412 is opposite to the cover body 21 and a gap is reserved to form the atomizing cavity 60.
The cover body 21 in some embodiment may present a tabular shape, its bottom surface is concave with four mounting holes 24 formed thereon, for accommodating two magnetic elements 26 and two electrode poles 27 respectively; the magnetic elements 26 are used for magnetically adsorbing the atomizer of the electronic cigarette and the power device to form a stable mechanical connection. The cover body 21 may also be provided with two electrode poles 27 in electrical connection with the heating body 42 on the atomizing surface 412 of the porous body 41; after the atomizer of the electronic cigarette and the power device are magnetically adsorbed together, the two electrode poles 27 are electrically connected to positive and negative electrodes of the power device respectively, so as to supply power to the heating body 42.
What more important in the embodiment is to define an air inlet 25 on the cover body 21, for external air to enter the atomizing cavity 60 when a user sucks the smoking port A; the position of the air inlet 25 is not directly opposite to the atomizing surface 412, but located at an end part of the cover body 21 close to the second side wall 140 of the outer shell 10, that is, the air inlet 25 and the notch 511 are located at two sides of the atomizing cavity 60 along the thickness direction of the outer shell 10 respectively, such that the airflow in the atomizing cavity 60 can pass through the whole atomizing cavity 60 when the user smokes.
Meanwhile, during the arrangement, the heating body 42 is arranged at a central position of the atomizing surface 412, such that the aerosol can be released to the middle of the atomizing cavity 60 as much as possible, thereby reducing the diffusion towards the areas of corners; meanwhile, the heating body 42 and the air inlet 25 are staggered with each other, to prevent the entered airflow dispersing the aerosol and facilitate the concentration of airflow. Further, in a preferred design, as shown in FIG. 7, three or more air inlets 25 are defined in parallel along the width direction, such that the parallel-arrangement direction is perpendicular to the atomizing surface 412 extending along the thickness direction or the airflow direction running through the atomizing cavity 60 along the thickness direction; meanwhile, the heating body 42 is also arranged on the atomizing surface 42 along the width direction, and the span L of arrangement of the air inlets 25 preferably is greater than the length M of extension of the heating body 42 as shown in FIG. 3, so that the aerosol can be carried away within the scope of airflow.
During the smoking process, the path direction of the airflow can refer to FIG. 6, that is, the external air enters the atomizing cavity 60 from the air inlet 25 close to the second side wall 140, then runs through the whole space of the entire atomizing cavity 60, and then is exported to the first gas channel 5213, the gas guide hole 5212 and the insert hole 534 from the notch 511 close to the first side wall 130, and finally enters the smoke conveying pipe 11 until the smoking port A where it is inhaled. Thus, the aerosol in the atomizing cavity 60 can be carried away as much as possible to reduce retention, which improves the efficiency of smoking and prevents the production of condensed liquid in the atomizing cavity 60.
Based on variable embodiments of the present disclosure, FIG. 8 shows a shape of another air inlet 25 a; there is one air inlet 25 a defined on the end cover 20 a, which presents a waist-type hole extending along the width direction or an elongated slit and the like, and its length L of extension is greater than the length M of extension of the heating body 42 a.
For the same purpose as above, in one embodiment the inlet and outlet direction of the airflow in the atomizing cavity 60 can be changed to run through the atomizing cavity 60 along the width direction W of the atomizer from the above mode of running through the atomizing cavity 60 along the thickness direction of the atomizer. Specifically, in the deformation implementation the design structure can refer to FIG. 9.
The atomizer includes an outer shell 10 b, and a smoke conveying pipe 11 b arranged inside the outer shell 10 b along the axial direction, wherein an liquid storage cavity 30 b configured for storing an liquid is formed between the smoke conveying pipe 11 b and an inner wall of the outer shell 10 b.
The outer shell 10 b is also provided with an end cover 20 b, an atomizing assembly 40 b and a sealing assembly 50 b, wherein a porous body of the atomizing assembly 40 b includes an atomizing surface 412 b opposite to the end cover 20 b, and an atomizing cavity 60 b is formed between the atomizing surface 412 b and the end cover 20 b.
This embodiment is different from the above embodiment in that an air inlet 25 b is defined on one side wall of the outer shell 10 b along the width direction, so that an airflow enters from one side of the atomizing surface 421 b along the width direction, runs through the atomizing surface 60 b along the width direction along the direction indicated by an arrow R3 shown in the figure and finally flows out from another side of the atomizing surface 412 b along the width direction.
Of course, in this implementation, it is needed to make a corresponding adjustment to the structure of the airflow channel on the sealing assembly 50 b; specifically, on the basis of the above embodiment, the notch 511, the first gas channel 5213 and the gas guide hole 5212 described in the above embodiment that are defined opposite to one side wall along the thickness direction can be adjusted to be opposite to one side wall along the width direction shown in FIG. 8, and they are located on one side of the atomizing surface 412 b opposite to the air inlet 25 b along the width direction. The technical staff can make a corresponding adjustment to the structure of the parts involved in this airflow mode with reference to the above description to ensure the airflow to largely run through the atomizing cavity 60. Thus, the aerosol in the atomizing cavity 60 b can be carried away as much as possible to reduce retention, which improves the efficiency of smoking and prevents the production of condensed liquid in the atomizing cavity 60 b.
The embodiment of the present disclosure further provides an electronic cigarette product; as shown in FIG. 10, the structure includes an atomizing device 100 configured for atomizing an liquid, and a power device 200 configured for supplying power to the atomizing device 100.

More specifically, the atomizing cavity 121′ further defines therein a collection cavity 123′ configured for collecting a condensed liquid formed by aerosol condensation; in the present embodiment, the collection cavity 123′ is located at the bottom of the atomizing cavity 121′, so that the condensed liquid is collected into the collection cavity 123′ under the action of gravity; a side wall of the atomizing cavity 121′ close to the air inlet channel 122′ is provided with a shielding part 124′, a projection of the shielding part 124′ in the direction of extension of the air inlet channel 122′ at least covers the section of partial of the air inlet channel 122′ perpendicular to the direction of extension, so as to prevent a condensed liquid in the atomizing cavity 121′ flowing into the air inlet channel 122′; in this way, when the aerosol generated as the atomizing core 2′ heats an liquid is diffused in the atomizing cavity 121′, since the temperature of the side wall of the atomizing cavity 121′ generally is low, the aerosol will be cooled on the side wall to generate a condensed liquid, and the accumulated condensed liquid will flow downwards along the side wall of the atomizing cavity 121′ under the action of gravity; when some condensed liquid flows close to the air inlet channel 122′, it will be blocked by the shielding part 124′ and cannot enter the air inlet channel 122′; in addition, if the liquid leaks because of untight sealing between the atomizing core 2′ and the liquid storage cavity 111′, when the leaked liquid flows close to the air inlet channel 122′ along the inner wall of the atomizing cavity 121′, it will be blocked by the shielding part 124′ too. The condensed liquid or the liquid will only converge into the collection cavity 123′, which prevents the condensed liquid or the liquid leaking through the air inlet channel 122′ and avoids the atomizing assembly 10′ from liquid leaking. The user experience of the electronic cigarette 100′ is better. Combined with FIG. 1 to FIG. 10, the air inlet channel 122′ in the present embodiment is equivalent to the air inlet 25 in the previous embodiment.
According to the above electronic cigarette 100′, by arranging the collection cavity 123′ configured for collecting a condensed liquid in the atomizing cavity 121′ of the main body 1′ of the atomizing assembly 10′, the condensed liquid formed in the atomizing cavity 121′ by the aerosol generated when the atomizing core 2′ heats the liquid can be collected by the collection cavity 123′; in addition, the shielding part 124′ that can block the condensed liquid entering the air inlet channel 122′ is arranged on the side wall of the atomizing cavity 121′, thus the condensed liquid on the side wall of the atomizing cavity 121′ will be blocked by the shielding part 124′ when flowing to be above the air inlet channel 122′ and cannot flow into the air inlet channel 122′, which effectively prevents the condensed liquid leaking through the air inlet channel 122′ and avoids the atomizing assembly 10′ from liquid leaking. The user experience of the electronic cigarette 100′ is better.
Referring to FIG. 12 to FIG. 13, in one embodiment, the shielding part 124′ includes an liquid blocking slope 1241′, which is arranged on the side wall of the atomizing cavity 121′ obliquely, and the atomizing cavity 121′ further defines therein a liquid conveying channel 120′ configured for connecting the liquid blocking slope 1241′ and the collection cavity 123′. Specifically, in the present embodiment, the liquid blocking slope 1241′ is arranged on the side wall of the atomizing cavity 121′ obliquely in a direction away from the air inlet channel 122′, and an included angle α between the liquid blocking slope 1241′ and the inner wall of the atomizing cavity 121′ is 30-85 degrees, wherein the a preferably selects 60 degrees. In the present embodiment, the shielding part 124′ is arranged between the atomizing cavity 121′ and the air inlet channel 122′, the aerosol will not enter the air inlet channel 122′, nor generate a condensed liquid inside the air inlet channel 122′; the condensed liquid will be generated in the atomizing cavity 121′ and the air outlet channel 112′ only; due to the included angle α, a hook shaped groove is formed between the liquid blocking slope 1241′ and the inner wall of the atomizing surface 121′, the condensed liquid will be blocked by the groove when flowing towards the air inlet channel 122′ along the inner wall of the atomizing cavity 121′ and cannot flow into the air inlet channel 122′; since the atomizing cavity 121′ further defines therein a liquid conveying channel 120′ configured for connecting the liquid blocking slope 1241′ and the collection cavity 123′, the condensed liquid inside the groove will flow through the liquid conveying channel 120′ to the collection cavity 123′ to be collected, which avoids the condensed liquid being accumulated on the liquid blocking slope 1241′ to overflow to the air inlet channel 122′ and effectively prevents the condensed liquid leaking from the air inlet channel 122′.
Of course, referring to FIG. 14, in another embodiment, the liquid blocking slope 1241′ may extend towards the air inlet channel 122′ from the inner wall of the atomizing cavity 121′, then included angle β between the liquid blocking slope 1241′ and the inner wall of the atomizing cavity 121′ is an obtuse angle, wherein β is 100-160 degrees, preferably 135 degrees. In this way, a baffle 125′ is arranged between the collection cavity 123′ and the air inlet channel 122′, and the baffle 125′ is configured for isolating the inlet channel 122′ from the collection cavity 123′; one end of the baffle 125′ close to the atomizing core 2′ is spaced apart from the shielding part 124′, thus the air entering from the inlet channel 122′ flows between the baffle 125′ and the shielding part 124′; one end of the liquid blocking slope 1241′ away from the side wall of the atomizing cavity 121′ extends to be above the collection cavity 123′ or into the collection cavity 123′, such that the condensed liquid can flow into the collection cavity 123′ to be collected along the liquid blocking slope 1241′.
Referring to FIGS. 12 to 13 and FIG. 16, in one embodiment, the atomizing core 2′ includes an atomizing surface 211′, the atomizing surface 211′ preferably is arranged facing the collection cavity 123′, the shielding part 124′ further includes an air guide slope 1242′, which is configured for guiding the air entering from the air inlet channel 122′ to flow towards the atomizing surface 211′. Specifically, in the present embodiment, the atomizing core 2′ includes a porous substrate 21′ and a heating body 22′, wherein the heating body 22′ is arranged on the porous substrate 21′, for example, the heating body 22 may be arranged on an outer surface of the porous substrate 21′, or inside the porous substrate 21′, through integrally forming.

Further, in the above embodiment, the air inlet 1221′ presents a rectangle, the heating body 22′ is arranged extending on the atomizing surface 211′, and the direction of extension is parallel to the length direction of the air inlet 1221′, further, the length of the air inlet 1221′ is at least equal to the length of extension of the heating body 22′ on the atomizing surface 211′, such that the air blown towards the atomizing surface 211′ from the air inlet 1221′ can completely cove the heating body 22′, thereby carrying away the aerosol generated when the heating body 22′ heats the liquid as much as possible and reducing the aerosol remained in the atomizing cavity 121′.

During installation, the atomizing cover 3′ and the atomizing core 2′ may be fixed on the base 12′ in advance and then the base 12′ is installed on one end of the shell 11′ to complete the installation of the atomizing assembly 10′. During disassembly, it is only needed to remove the base 12′ from the shell 11′, then the atomizing cover 3′ and the atomizing core 2′ can be taken out together. Since the atomizing core 2′ is easy to damage or age during usage, the integral assembly or disassembly mode of the atomizing cover 3′ and the atomizing core 2′ on the base 12′ is convenient to replace the atomizing core 2′. The maintenance of the atomizing assembly 10′ is convenient.
Further, referring to FIG. 11 to FIG. 12, the atomizing assembly 10′ further includes a conductive ejector pin 4′, wherein the number of the conductive ejector pins 4′ is 2, the two conductive ejector pins 4′ are both electrically connected to the heating body 22′ of the atomizing core 2′, the conductive ejector pin 4′ may be connected to an external power source, such that the heating body 22′ is electrified and heated to heat the liquid to generate an aerosol. Specifically, referring to FIG. 17 and FIG. 18, in the present embodiment, the base 12′ defines a fixed hole 128 for installing the conductive ejector pin 4′, one end of the conductive ejector pin 4′ is arranged in the fixed hole 128′ while the other end presses against the heating body 22′ on the surface of the porous substrate 21′; more specifically, the conductive ejector pin 4′ is provided with a flange 41; when one end of the conductive ejector pin 4′ is inserted into the fixed hole 128′, the flange 41′ presses against one end of the fixed hole 128′ close to the heating body 22′, so as to limit the depth of the conductive ejector pin 4′ inserted into the fixed hole 128′. In the present embodiment, the fixed hole 128′ runs through the base 12′ to communicate with the outside, the conductive ejector pin 4′ is exposed out of the outer surface of the base 12′ after one end is inserted into the fixed hole 128′, for electrical connection to an external power source (for example, battery assembly 20′). During assembly, one end of the conductive ejector pin 4′ is inserted into the fixed hole 128′ first, then the atomizing cover 3′ is covered on the atomizing core 2′ and is installed in the base 12′ together with the atomizing core 2′, meanwhile the heating body 22′ of the atomizing core 2′ is enabled to press against the conductive ejector pin 4′, and finally the base 12′ is installed on one end of the shell to complete the assembly of the atomizing assembly 10′.
