Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomizer, in particular to a planar atomizing core assembly with double needle structure and electrical connection. BACKGROUND

[0002] The heating atomizing core and its atomizing assembly are the core components of liquid atomizing products, which are used to heat the liquid to make it into a misty aerosol form. In order to ensure that the user obtains a good taste, the atomizing core and its assembly are required to heat the atomizing liquid uniformly, consistently and delicately, reduce the condensation phenomenon and have a high taste restoration degree.

[0003] The atomizing core assembly is usually barrel-shaped or planar. The drum-shaped atomizing core assembly usually uses a cotton core with a mesh or wire heating wire structure, which has a simple air passage structure, good atomization restoration degree, but the assembly is not easy to mechanically mass-produce and assemble, has poor consistency, and is easy to explode and leak oil. The existing atomizing assembly based on the planar atomizing core usually uses a ceramic atomizing core or a planar heating wire with a cotton core structure, which has the advantages of easy production and assembly and good consistency, but has the disadvantage of poor taste restoration degree.

[0004] The reason why the existing planar atomizing core has a poor taste restoration degree is that the atomizing assembly of the planar atomizing core has the atomizing surface facing the air inlet, relies on the airflow entering the air inlet to impact the atomizing surface, and the smoke passes through the atomizing core surface in the reverse direction, is collected into the air outlet channel from the channels on both sides of the atomizing core, and then enters the user's mouth. The smoke produced by the external airflow with relatively low temperature directly impacting the atomizing surface is easy to condense, and the condensed liquid is deposited near the bottom air inlet. Then, the smoke is divided into two parts and collected into the air outlet channel from the channels on both sides of the atomizing core. During this process, the smoke passes through the flow divider and a long channel, which causes the smoke to further condense on the side wall of the channel.

[0005] Therefore, the atomizing assembly with the atomizing surface facing upward and toward the mouthpiece has the following disadvantages of the planar atomizing core:

[0006] 1) Low taste restoration degree, most of the atomized substances such as flavorings are condensed in advance and do not enter the user's mouth;

[0007] 2) Low temperature of the taste, the smoke is cooled a lot during the whole transmission process;

[0008] 3) Low TPM value (atomized weight per puff), a large amount of condensed liquid weight generated per puff is not included in the TPM value;

[0009] 4) A large amount of condensed liquid causes low efficiency of the atomizing core, which cannot exert its capacity;

[0010] 5) It is difficult to achieve electrical connection between the atomizing core and the external control power supply, which causes assembly difficulty and is difficult to produce. SUMMARY

[0011] The purpose of the present application is to provide a flat atomization core assembly with double-top-needle structure electrical connection to solve the problems of low taste reduction degree, low atomization efficiency, and difficulty in electrical connection between the atomization core and external control power supply.

[0012] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a flat atomization core assembly with double-top-needle structure electrical connection, comprising:

[0013] The lower cover is provided with two air inlet holes arranged symmetrically on one opposite side, and the lower cover is provided with two lower top needles arranged in parallel;

[0014] The atomization core bin comprises a liquid storage cavity, a liquid inlet, a first mounting groove, an atomization core, a gas guide channel, and a first lower top needle hole. The liquid inlet is communicated to the liquid storage cavity at the bottom. The first mounting groove extends downward from the top surface of the atomization core bin. The first mounting groove is provided with an atomization core groove on the bottom surface. The bottom surface of the atomization core groove is communicated to the liquid storage cavity. The atomization core is placed in the atomization core groove. The thickness of the atomization core is less than the depth of the atomization core groove. The atomization core is provided with an electrode on the atomization surface. The atomization core bin is provided with symmetrically arranged gas guide channels on both sides. The gas guide channel comprises an axial part channel and a radial part channel. The axial part channel is positioned corresponding to the air inlet hole. The radial part channel extends to the side wall of the atomization core groove at one end and forms an air inlet.

[0015] The upper cover is fixedly installed in the first mounting groove. The space of the atomization core groove between the bottom surface of the upper cover and the atomization surface of the atomization core forms a gas mixing cavity. The air inlet is positioned corresponding to the gas mixing cavity. The upper cover is provided with an air outlet communicated to the gas mixing cavity. The upper cover is also provided with an upper top needle and a second lower top needle hole. The bottom of the upper top needle contacts the electrode after passing through the upper cover. The top of the upper top needle is provided with a horizontally extending piece. The top of the lower top needle passes through the first lower top needle hole and the second lower top needle hole in turn and then contacts the horizontally extending piece.

[0016] Further description of the above technical scheme:

[0017] The first recess is arranged on the bottom surface of the lower cover. The lower top needle is fixedly installed on the bottom surface of the first recess.

[0018] Further description of the above technical scheme:

[0019] The lower cover is provided with symmetrically arranged buckle blocks on both sides.

[0020] Further description of the above technical scheme:

[0021] The side hole wall of the first lower top needle hole extends to the side surface of the atomization core bin to form an opening.

[0022] Further description of the above technical scheme:

[0023] The second groove is arranged on the top surface of the upper cover, and the horizontal extension piece is fixedly installed in the second groove.

[0024] Further description of the above technical solution:

[0025] The upper cover is provided with symmetrical liquid inlets arranged on both sides.

[0026] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0027] 1. In the present application, the atomizing core bin realizes liquid and airflow isolation, which not only provides sufficient atomizing liquid to the atomizing core through the liquid inlet, but also directly guides the atomized gas into the gas outlet through the air guide channel, so that the external air is not directly blown to the atomizing surface, the atomizing surface is not cooled, and the newly atomized smoke is not condensed, but the atomized smoke directly enters the air outlet channel and enters the user's oral cavity, thereby improving the atomization reduction degree.

[0028] 2. In the present application, when the electrode and the external power supply are located at different sides of the atomizing core, the upper and lower two pairs of thimbles are used to realize the electrical connection between the atomizing core and the external power supply, thereby solving the problem of difficult electrical connection when the atomizing surface of the atomizing core faces the air outlet, and the structure is simple and suitable for batch assembly production.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0040] Embodiment 1

[0041] Please refer to Figures 1-4 The present application provides a technical scheme: a double-ejector-pin-structured planar atomizing core assembly electrically connected, comprising:

[0042] The lower cover 1 is provided with two symmetrically arranged air inlet holes 11 on one side, and the lower cover 1 is provided with two parallel arranged lower ejector pins 12, which can be fixedly installed in the fixing holes on the lower cover 1 by interference fit or the like;

[0043] The atomization core bin 2 includes a liquid storage cavity 21, a liquid inlet 22, a first mounting groove 23, an atomization core 24, a gas guide channel 25 and a first lower thimble hole 26. The liquid inlet 22 extends inward from the top surface of the atomization core bin 2. The bottom of the liquid inlet 22 is connected to the liquid storage cavity 21. The first mounting groove 23 extends downward from the top surface of the atomization core bin 2. The bottom surface of the first mounting groove 23 is provided with an atomization core groove. The bottom surface of the atomization core groove is connected to the liquid storage cavity 21. The atomization core 24 is placed in the atomization core groove. The thickness of the atomization core 24 is less than the depth of the atomization core groove. The atomization surface of the atomization core 24 is provided with an electrode 241. The two sides of the atomization core bin 2 are provided with symmetrically arranged gas guide channels 25. The gas guide channels 25 are in the shape of “L”. The gas guide channels 25 include an axial part channel 251 and a radial part channel perpendicular to the axial part channel 251. The axial part channel 251 is arranged along the axis direction of the atomization core bin 2. The axial part channel 251 is located corresponding to the air inlet hole 11. One end of the radial part channel extends to the side wall of the atomization core groove and forms an air inlet.

[0044] The upper cover 3 is fixedly installed in the first mounting groove 23. The space between the bottom surface of the upper cover 3 and the atomization surface of the atomization core 24 forms a gas mixing cavity. The air inlet is located corresponding to the gas mixing cavity. The upper cover 3 is provided with an air outlet 33 connected to the gas mixing cavity. The upper cover 3 is also provided with an upper thimble 31 and a second lower thimble hole 32. The bottom of the upper thimble 31 contacts the electrode 241 after passing through the upper cover 3. The longitudinal needle structure of the upper thimble 31 can be fixedly installed in the mounting hole of the upper cover 3 by interference fit or the like. The top of the upper thimble 31 is provided with a horizontally extending piece 311. The bottom of the lower thimble 12 contacts the horizontally extending piece 311 after sequentially passing through the first lower thimble hole 26 and the second lower thimble hole 32.

[0045] Compared with the traditional planar atomization core assembly which heats the atomization surface to face the air inlet hole, the atomization core assembly in the application reversely installs the atomization core so that the atomization surface directly faces the air outlet channel. In this way, the incoming air is not directly blown to the atomization surface, but is sent to the air outlet through the side channel of the atomization core to directly enter the user's oral cavity. In the whole atomization process of the planar atomization core assembly in the application, the incoming air from outside does not directly blow to the atomization surface, does not cool the atomization surface, and does not cause the just atomized smoke to condense. The atomized smoke directly enters the air outlet channel and enters the user's oral cavity, improving the atomization reduction degree.

[0046] When the electrode and the external power source are located at different sides of the atomization core, the upper and lower thimble structures are used to realize the electrical connection between the atomization core and the external power source, solving the problem of difficult electrical connection when the atomization surface of the atomization core faces the air outlet. The structure is simple and suitable for mass production and assembly.

[0047] The lower cover 1 is provided with symmetrically arranged buckle blocks 14 on the two sides, facilitating the buckling installation of the lower cover 1 and the whole planar atomization core assembly.

[0048] The second groove 34 is arranged on the top surface of the upper cover 3, and the horizontally extending piece 311 is fixedly installed in the second groove 34, so as to effectively position and protect the horizontally extending piece 311 and the upper needle 31.

[0049] The liquid inlet 22 is arranged on the two sides of the upper cover 3 in a symmetrical manner, so as to effectively ensure the liquid supplementing efficiency of the liquid storage cavity 21.

[0050] Working principle: when the planar atomizing core assembly works, the liquid flows into the liquid storage cavity 21 through the liquid inlet 22, the liquid in the liquid storage cavity 21 enters the atomizing core 24 through the through hole on the bottom surface of the atomizing core groove, the atomizing surface on the upper side of the atomizing core 24 is powered through the electrode 241, the atomized liquid enters the gas mixing cavity, on the other hand, the fresh gas enters from the two gas inlets 11 on the lower cover 1, and then is guided into the gas mixing cavity along the gas guiding channel 25 on the side wall of the atomizing core bin 2, and then the gas and the atomized liquid are guided into the gas outlet 33. The atomizing core bin 2 realizes the isolation of the liquid and the gas flow, which not only can provide sufficient atomizing liquid for the atomizing core 24 through the liquid inlet 22, but also can directly guide the atomized gas into the gas outlet 33 through the gas guiding channel 25, so that the external gas does not directly blow to the atomizing surface, and the atomizing surface is not cooled, and the atomized smoke directly enters the gas outlet channel and enters the user's oral cavity, thereby improving the atomization reduction degree.

[0051] The two electrodes 241 on the atomizing core 24 are in contact with the two upper needles 31 respectively, so as to form an electrical connection, the upper needle 31 is in an L-shaped structure, in addition to the longitudinal needle structure in contact with the electrode 241 on the atomizing core 24, the top end has a transversely extending flat beam structure, that is, the horizontally extending piece 311, the horizontally extending piece 311 is in contact with the needle end of the lower needle 12, so that the lower needle 12 and the upper needle 31 are electrically connected, thereby realizing the connection between the atomizing core and the external control power supply.

[0052] Embodiment 2

[0053] The first groove 13 is arranged on the bottom surface of the lower cover 1, and the lower needle 12 is fixedly installed on the bottom surface of the first groove 13.

[0054] The fixing hole of the lower needle 12 is arranged on the bottom surface of the first groove 13, so that the bottom end of the lower needle 12 does not protrude from the bottom surface of the lower cover 1, thereby effectively protecting the bottom end of the lower needle 12.

[0055] Embodiment 3

[0056] The one side hole wall of the first lower needle hole 26 extends to the side surface of the atomizing core bin 2 to form an opening.

[0057] The atomizing core bin 2 positions the lower needle 12 through the opening groove formed on the side surface, which is compared with the original hole (i.e. the first lower needle hole 26), and facilitates the assembly of the lower needle 12.

[0058] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
