Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizer technology, and in particular to a planar atomizer core assembly with a double-pin structure and electrical connection. Background Technology
[0002] The heated atomizing core and its atomizing components are the core components of liquid atomization products, used to heat the liquid and disperse it in the form of a mist-like aerosol. To ensure that users obtain a good taste, the atomizing core and its components must heat the atomized liquid evenly, consistently, and finely, reducing atomization condensation and achieving high flavor fidelity.
[0003] Atomizer coil assemblies are mostly available in barrel-shaped and planar designs. Among them, coil-type atomizer coil assemblies typically use a cotton wick with a mesh or filament heating wire structure. Their airflow structure is simple, and they offer good atomization fidelity. However, these assemblies are difficult to mass-produce and assemble mechanically, resulting in poor consistency and a tendency to splatter and leak. Existing atomizer coil-based assemblies often use ceramic atomizer coils or planar heating wires with a cotton wick structure. Their advantages include ease of production and assembly, and good consistency. However, their disadvantage is poorer flavor fidelity.
[0004] The reason why existing planar atomizer coils have poor flavor reproduction is that: in planar atomizer coils, the atomizing surface faces the air intake. The airflow entering through the air intake impacts the atomizing surface, forcing the vapor from the coil surface backwards through the channels on both sides of the coil into the exhaust channel, and then into the user's mouth. The relatively cool external airflow directly impacts the vapor produced by the atomizing surface, making the vapor condense very easily, and the condensate deposits near the bottom air intake. Then, the vapor splits into two parts and flows from both sides of the atomizer coil into the exhaust channel. During this process, the vapor is split and travels through a relatively long exhaust channel, causing further condensation, which then accumulates on the side walls of the exhaust channel.
[0005] Therefore, the atomizing component with its atomizing surface facing upwards and toward the mouthpiece results in the following disadvantages for a planar atomizing coil:
[0006] 1) The flavor reproduction is low, as most of the flavorings and other atomized substances condense prematurely and do not enter the user's mouth;
[0007] 2) The temperature of the smoke is low, and the smoke cools down significantly during the entire delivery process;
[0008] 3) The TPM value (weight per atomization) is low, and the weight of a large amount of condensate generated per atom is not included in the TPM value;
[0009] 4) The generation of a large amount of condensate results in low efficiency of the atomizing core, which cannot perform its function.
[0010] 5) The atomizing core and the external control power supply are difficult to connect electrically, which makes assembly difficult and production difficult. Utility Model Content
[0011] The purpose of this invention is to provide a planar atomizing core assembly with a double-pin structure and electrical connection, in order to solve the problems of low flavor reproduction, low atomization efficiency, and difficulty in achieving electrical connection between the atomizing core and the external control power supply in planar atomizing core assemblies with the atomizing surface facing upward and towards the mouthpiece.
[0012] To achieve the above objectives, this utility model adopts the following technical solution: a planar atomizing core assembly with a double-pin structure and electrical connection, comprising:
[0013] The lower cover has two symmetrically arranged air inlets on one opposite side, and two parallel lower ejector pins on the lower cover.
[0014] The atomizing core chamber includes a liquid storage chamber, a liquid inlet, a first mounting groove, an atomizing core, an air guide channel, and a first bottom pin hole. The bottom of the liquid inlet is connected to the liquid storage chamber. The first mounting groove extends downward from the top surface of the atomizing core chamber. An atomizing core groove is provided on the bottom surface of the first mounting groove. The bottom surface of the atomizing core groove is connected to the liquid storage chamber. The atomizing core is placed in the atomizing core groove. The thickness of the atomizing core is less than the depth of the atomizing core groove. An electrode is provided on the atomizing surface of the atomizing core. Symmetrically arranged air guide channels are provided on both sides of the atomizing core chamber. The air guide channels include an axial part channel and a radial part channel. The position of the axial part channel corresponds to the air inlet. One end of the radial part channel extends to the side wall of the atomizing core groove and forms an air inlet.
[0015] The top cover is fixedly installed in the first mounting groove. The space between the bottom surface of the top cover and the atomizing surface of the atomizing core forms a gas mixing chamber. The air inlet is located in the gas mixing chamber. The top cover is provided with an air outlet that connects to the gas mixing chamber. The top cover is also provided with an upper ejector pin and a second lower ejector pin hole. The bottom of the upper ejector pin passes through the top cover and contacts the electrode. The top of the upper ejector pin is provided with a horizontal extension plate. The top of the lower ejector pin passes through the first lower ejector pin hole and the second lower ejector pin hole in sequence and contacts the horizontal extension plate.
[0016] As a further description of the above technical solution:
[0017] A first groove is provided on the bottom surface of the lower cover, and the lower ejector pin is fixedly installed on the bottom surface of the first groove.
[0018] As a further description of the above technical solution:
[0019] The lower cover has symmetrically arranged buckle blocks on both sides.
[0020] As a further description of the above technical solution:
[0021] The first pin hole extends from one side of the hole wall to the side surface of the atomizing core chamber, forming an opening.
[0022] As a further description of the above technical solution:
[0023] A second groove is provided on the top surface of the cover, and a horizontal extension piece is fixedly installed in the second groove.
[0024] As a further description of the above technical solution:
[0025] The top cover has symmetrically arranged liquid inlets on both sides.
[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0027] 1. In this utility model, the atomizing core chamber achieves liquid and airflow isolation. It can not only provide sufficient atomizing liquid to the atomizing core through the liquid inlet, but also directly guide the atomized gas to the air outlet through the air guide channel. External air is not directly blown onto the atomizing surface, so it will not cool the atomizing surface or cause condensation of the freshly atomized smoke. Instead, the atomized smoke directly enters the air outlet channel and enters the user's mouth, improving the atomization reproduction degree.
[0028] 2. In this utility model, when the electrode and the external power supply are located on opposite sides of the atomizing core, an upper and lower pair of pin structures are used to realize the electrical connection between the atomizing core and the external power supply.

Furthermore, the structure is simple and suitable for mass assembly production. Attached Figure Description

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0040] Example 1
[0041] Please see Figure 1-4 This utility model provides a technical solution: a planar atomizing core assembly with a double-pin structure and electrical connection, comprising:
[0042] The lower cover 1 has two symmetrically arranged air inlets 11 on one opposite side. The lower cover 1 has two parallel lower ejector pins 12, which can be fixedly installed in the fixing holes on the lower cover 1 by means of interference fit or other means.
[0043] The atomizing core chamber 2 includes a liquid storage chamber 21, a liquid inlet 22, a first mounting groove 23, an atomizing core 24, an air guide channel 25, and a first bottom pin hole 26. The liquid inlet 22 extends inward from the top of the atomizing core chamber 2, and its bottom connects to the liquid storage chamber 21. The first mounting groove 23 extends downward from the top of the atomizing core chamber 2, and an atomizing core groove is provided on its bottom surface. The bottom surface of the atomizing core groove connects to the liquid storage chamber 21. The atomizing core 24 is placed in the atomizing core groove, and the thickness of the atomizing core 24 is less than the thickness of the air filter. The depth of the core groove, the atomizing surface of the atomizing core 24 is provided with electrodes 241, the atomizing core chamber 2 is provided with symmetrically arranged air guide channels 25 on both sides, the air guide channels 25 are "L" shaped, the air 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 axial direction of the atomizing core chamber 2, and the position of the axial part channel 251 corresponds to the air inlet 11. One end of the radial part channel extends to the side wall of the atomizing 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 atomizing surface of the atomizing core 24 forms a gas mixing chamber. The air inlet is located in the gas mixing chamber. The upper cover 3 is provided with an air outlet 33, which is connected to the gas mixing chamber. The upper cover 3 is also provided with an upper ejector pin 31 and a second lower ejector pin hole 32. The bottom of the upper ejector pin 31 passes through the upper cover 3 and contacts the electrode 241. The longitudinal needle structure of the upper ejector pin 31 can be fixedly installed in the mounting hole on the upper cover 3 by means of interference fit, etc. The top of the upper ejector pin 31 is provided with a horizontal extension piece 311. The top of the lower ejector pin 12 passes through the first lower ejector pin hole 26 and the second lower ejector pin hole 32 in sequence and contacts the horizontal extension piece 311.
[0045] Compared to traditional planar atomizing core components where the heating and atomizing surface faces the air inlet, the atomizing core component in this application is installed in reverse, with the atomizing surface directly facing the air outlet. This avoids the air intake blowing directly onto the atomizing surface; instead, the atomized vapor is delivered to the air outlet through a side channel of the atomizing core, directly entering the user's mouth. Throughout the atomization process of the planar atomizing core component in this application, external air intake does not blow directly onto the atomizing surface, thus preventing cooling and condensation of the freshly atomized vapor. The atomized vapor directly enters the air outlet and then the user's mouth, improving the atomization fidelity.
[0046] When the electrodes and the external power supply are located on opposite sides of the atomizing core, the upper and lower pairs of pins are used to achieve electrical connection between the atomizing core and the external power supply. This solves the problem of difficult electrical connection when the atomizing surface of the atomizing core faces the air outlet. Furthermore, the structure is simple and suitable for mass production.
[0047] The lower cover 1 has symmetrically arranged snap-fit blocks 14 on both sides, which facilitates the snap-fit installation of the lower cover 1 and the entire planar atomizing core assembly.
[0048] A second groove 34 is provided on the top surface of the upper cover 3, and the horizontal extension piece 311 is fixedly installed in the second groove 34 to effectively position and protect the horizontal extension piece 311 and the upper ejector pin 31.
[0049] The top cover 3 has symmetrically arranged liquid inlets 22 on both sides, which effectively ensures the liquid replenishment efficiency in the liquid storage chamber 21.
[0050] Working principle: When the planar atomizing core assembly is working, liquid flows downward into the liquid storage chamber 21 through the liquid inlet 22. The liquid in the liquid storage chamber 21 enters the atomizing core 24 through the through hole on the bottom surface of the atomizing core slot. The atomizing surface on the upper side of the atomizing core 24 is powered by the electrode 241 to realize the atomization of the liquid. The atomized liquid enters the gas mixing chamber. On the other hand, fresh gas enters from the two air inlets 11 on the lower cover 1 and is introduced into the gas mixing chamber along the air guide channel 25 on the side wall of the atomizing core chamber 2. Then, the gas and the atomized liquid are introduced together to the air outlet 33. The atomizing core chamber 2 realizes the isolation of liquid and airflow. It can not only provide sufficient atomizing liquid to the atomizing core 24 through the liquid inlet 22, but also directly introduce the atomized gas to the air outlet 33 through the air guide channel 25. The external air intake does not blow directly onto the atomizing surface, so it will not cool the atomizing surface or cause condensation of the freshly atomized smoke. The atomized smoke directly enters the air outlet channel and enters the user's mouth, improving the atomization degree.
[0051] The two electrodes 241 on the atomizing core 24 are in contact with the two upper pins 31 respectively, forming an electrical connection. The upper pin 31 has an L-shaped structure. In addition to the longitudinal pin structure that contacts the upper electrode 241 of the atomizing core 24, the top end has a horizontally extending flat beam structure, namely a horizontal extension plate 311. The horizontal extension plate 311 contacts the pin end of the lower pin 12, so that the lower pin 12 and the upper pin 31 are electrically connected, thereby realizing the connection between the atomizing core and the external control power supply.
[0052] Example 2
[0053] Based on the above embodiments, this embodiment further improves upon the following technical solution: a first groove 13 is provided on the bottom surface of the lower cover 1, and the lower ejector pin 12 is fixedly installed on the bottom surface of the first groove 13.
[0054] The fixing hole of the lower ejector pin 12 is set on the bottom surface of the first groove 13, so that the bottom end of the lower ejector pin 12 does not protrude from the bottom surface of the lower cover 1, effectively protecting the bottom end of the lower ejector pin 12.
[0055] Example 3
[0056] Based on the above embodiments, this embodiment further improves upon the following technical solution: the side wall of the first lower pin hole 26 extends to the side surface of the atomizing core chamber 2 to form an opening.
[0057] The atomizing core chamber 2 positions the lower ejector pin 12 through an opening groove formed on its side surface, which facilitates the assembly of the lower ejector pin 12 compared to the original channel (i.e., the first lower ejector pin hole 26).
[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
