TECHNICAL FIELD

[0002] The electronic atomization equipment comprises an atomization device and a power supply device for supplying power to the atomization device, and the atomization device is internally constructed with a liquid storage cavity, an airflow channel and a heating core assembly. The power supply device is provided with a receiving groove, and the atomization device is installed in the receiving groove and electrically connected with the power supply device. The power supply device can provide power for the atomization device to drive the heating core assembly to atomize the solution absorbed from the liquid storage cavity into an aerosol and discharge the aerosol. In the mainstream heating core assemblies on the market, the liquid absorption carrier is mainly microporous ceramic and cotton material. The heating body is sintered on the microporous ceramic carrier, and the heating wire is wound around the cotton material, the heating net is wrapped, and the heating piece is contacted, etc. The method of sintering the heating body on the microporous ceramic to form a ceramic heating body is relatively stable, but the liquid guiding rate and taste of the ceramic heating body are relatively weaker than those of the cotton material.

[0041] Reference should be made to Figures 1 to 9The embodiment of the present application provides a modular heating core assembly 100 applied to an atomization device 1000, the atomization device 1000 comprising a shell 200 and a base 300, one end of the shell 200 being provided with a mist outlet 210, the other end being provided in an open manner, the base 300 blocking the opening and surrounding the inner wall of the shell 200 to form a liquid storage cavity 230, the liquid storage cavity 230 being used for containing water, aromatic liquid, mosquito repellent liquid, medicinal liquid, tobacco liquid and the like, different atomization devices being formed according to different internal solutions, for example, a humidifier, an aromatherapy device, a mosquito repellent device, a medicinal atomizer and an electronic cigarette. In the embodiment, the electronic cigarette is taken as an example.

[0042] Specifically, as shown in the drawings, Figure 3 In combination Figure 5 In the embodiment of the present application, the heating core assembly 100 comprises a heating core 40, a base 30 and a main body 20, the main body 20 being in a tubular shape, the upper end of the main body 20 being provided with an air outlet 12, the lower end of the main body 20 being provided with a mounting hole for inserting the base 30, and the side wall of the main body 20 being provided with a liquid inlet hole 21 for communicating with the space in the tube. The heating core 40 comprises liquid absorbing cotton 41 and a heating element 42 in contact with the liquid absorbing cotton 41, the heating element 42 comprising a conductive lead 422 for conducting electricity and a heating portion 421 for heating under the action of an electric current, the heating portion 421 being capable of adopting a nickel-chromium alloy heating wire, a steel mesh, a perforated steel tube, a ceramic heating sheet and the like, and in the embodiment, a nickel-chromium alloy heating wire is selected and wound in the middle of the liquid absorbing cotton 41, so that an atomization section 412 is formed in the middle of the liquid absorbing cotton 41. The upper end of the base 30 is used for inserting the main body 20 along the mounting hole, and provides support for the heating core 40 of the heating core assembly 100 in the main body 20, the lower end of the base 30 being provided with a connecting seat 34, the connecting seat 34 being exposed to the outside from the main body 20 and being used for connecting with the base 300 of the external atomization device 1000. The lower end surface of the connecting seat 34 is provided with an insertion blind hole 341 and a wire passing hole 342, the wire passing hole 342 being provided through the base 30 from the upper end surface of the base 30 to the connecting seat 34 protruding from the lower end of the base 30; the conductive lead 422 of the heating core 40 is bent in the insertion blind hole 341 after passing through the wire passing hole 342 from the upper end of the base 30, and the insertion blind hole 341 is used for inserting the conductive electrode 340 provided on the base 300 of the external atomization device 1000. When installed, only the base 300 of the external atomization device 1000 is needed to cover the connecting seat 34, and the conductive electrode 340 of the base 300 is inserted into the insertion blind hole 341, so that the wire does not need to be welded, and the point connection position of the conductive electrode 340 and the conductive lead 422 is located in the insertion blind hole 341, the conductive electrode 340 of the base 300 of the atomization device 1000 is completely fitted with the base 300, and compared with the existing mode of extending the conductive lead 422 to the mounting hole 310 of the conductive electrode 340 of the base 300 and then pressing the conductive electrode 340, the risk of liquid leakage is effectively reduced.

[0043] The beneficial effects of the present application are that the upper end of the base 30 is inserted into the main body 20 and provides support for the heating core 40 inside the main body 20, the lower end of the base 30 is provided with a connecting seat 34 for connecting with the base 300 of the external atomization device 1000, and the heating core 40 is packaged into an assembly by the main body 20 and the base 30, so that when it is transported to the downstream factory or downstream station, the heating core 40 will not be contaminated. At the same time, after the packaging is completed, the heating core 40 is located in the main body 20 and the base 30, and will not be deformed, thereby reducing the damage to the heating core 40 caused by the production process and production environment of the downstream factory, and causing the phenomenon of poor taste consistency. At the same time, the lower end surface of the connecting seat 34 is provided with an insertion blind hole 341 and a wire passing hole 342, and the conductive lead 422 of the heating core 40 is bent and preassembled in the insertion blind hole 341 after passing through the wire hole, and the insertion blind hole 341 is provided for the conductive electrode 340 provided on the base 300 of the external atomization device 1000. Therefore, after independent packaging, a modular heating core assembly 100 can be formed, and a standard part can be formed, without wire welding, which can be used in various atomization devices 1000. When the appearance of the atomization device 1000 changes, only the position of the heating core assembly 100 needs to be reserved to achieve universality, avoiding the need to re-tune the taste for each product.

[0044] Specifically, as shown in Figure 5 In the embodiment of the present application, the base 30 is interference-fitted in the mounting port, the connecting seat 34 is located outside the mounting port, and the number of connecting seats 34 is two, the two connecting seats 34 are spaced apart, and the spacing area is provided with an air inlet 36 for separating and installing the two conductive leads 422 of different polarities to avoid short circuit, and at the same time, the two conductive electrodes 340 are inserted into the two insertion blind holes 341, thereby improving the connection strength of the base 30 and the base 300 of the external atomization device 1000. Further, the outer surface of the connecting seat 34 is located inside the outer surface of the main body 20, the outer surface of the main body 20 provided with the liquid inlet hole 21 is used for interference-fitting with the base 300 of the external atomization device 1000, and the outer wall of the connecting seat 34 is clearance-fitted with the base 300 of the atomization device 1000. Therefore, when the heating core assembly 100 is installed in the base 300 of the atomization device 1000, the outer wall of the main body 20 is interference-fitted with the base 300 of the atomization device 1000, and the outer wall of the connecting seat 34 is spaced apart from the inner wall of the base 300 of the atomization device 1000, forming an air guide channel to ensure that external airflow can flow into the inside of the main body 20 from the air inlet. At the same time, the base 30 is clearance-fitted with the base 300, preventing the base 300 from being detached, and the friction between the base 30 and the base 300 is large, which causes the base 30 to be pulled out.

[0045] Specifically, as shown in Figure 5 In combinationFigure 7 As shown in this embodiment, the insertion blind hole 341 has a wire-passing notch 3411 communicating with the wire-passing through hole 342. The conductive lead 422 passes through the wire-passing notch 3411 and then bends inside the insertion blind hole 341. This prevents the conductive lead 422 from protruding from the end face of the connector 34, thus avoiding the phenomenon of the conductive lead 422 being squeezed and misaligned when the base 300 and the connector 34 are connected. In addition, this also allows for positioning and installation of the conductive lead 422, facilitating automated processing and production.

[0046] Specifically, such as Figure 7 As shown in this embodiment, the connector 34 is provided with a notch 3412 at the position of the insertion blind hole 341 opposite to the wire notch 3411. The notch 3412 extends along the protruding direction of the connector 34, thereby facilitating the external fixture to bend the conductive lead 422 into the insertion blind hole 341, while releasing the stress when the conductive electrode 340 is inserted, and preventing the inner wall of the insertion blind hole 341 from cracking when the conductive electrode 340 is inserted into the insertion blind hole 341.

[0047] Specifically, such as Figure 7 As shown in this embodiment, the opening on the outside of the through hole 342 is gradually widened to form a glue injection groove 3421. Glue is applied to fix the conductive lead 422, preventing deformation of the absorbent cotton 41 caused by the internal heating element 421 exerting force on the absorbent cotton 41 when the conductive electrode 340 is subsequently pressed in. The through notch 3411 is connected to the glue injection groove 3421 of the through hole 342, and the corner of the through notch 3411 is provided with an arc transition. During glue application, some glue flows to the through notch 3411, solidifies, and forms a protective layer, preventing the bent conductive lead 422 from breaking due to shear force at the through notch 3411 when the conductive electrode 340 is inserted.

[0048] Furthermore, such as Figure 6 Combination Figure 7To ensure a large atomization space and avoid the heating part 421 from contacting the base 30, in the embodiment, the upper end of the base 30 is provided with two spaced support arms 31, and the upper end of each of the two support arms 31 is further provided with a pre-assembly gap 311. The two pre-assembly gaps 311 are oppositely arranged and penetrate the side wall of the two support arms 31 to form the liquid absorbing cotton 41 of the heating core 40. The two ends of the liquid absorbing cotton 41 are pre-arranged in the two pre-assembly gaps 311 and partially extend from the pre-assembly gaps 311 to form a liquid absorbing section 411. The middle part of the liquid absorbing cotton 41 is suspended between the two support arms 31 and contacts the heating element 42 to form an atomization section 412. The liquid absorbing cotton 41 is suspended and arranged by the two support arms 31 to prevent the heating part 421 in the middle part of the liquid absorbing cotton 41 from contacting the base 30. Meanwhile, a large atomization space is formed to ensure that the external airflow rapidly enters the air inlet 36 to provide airflow for the heating part 421 to atomize the solution. Meanwhile, the inner wall of each side of the main body 20 is provided with a pressing arm 11. When the base 30 is inserted into the main body 20, the pre-assembly gap 311 is opposite to the liquid inlet hole 21, the pressing arm 11 is inserted into the pre-assembly gap 311, and the liquid absorbing section 411 is pressed in the pre-assembly gap 311 to ensure that the liquid absorbing cotton 41 is arranged between the two support arms 31 to prevent the liquid absorbing cotton 41 from being deviated from the liquid inlet hole 21 to cause the solution to directly flow into the liquid inlet hole 21.

[0049] Specifically, as shown in the figure, Figures 6 to 8 In the embodiment, to facilitate the installation of the liquid absorbing cotton 41, the pre-assembly gap 311 is in a U shape. When the two ends of the liquid absorbing cotton 41 are placed at the lower end of the U-shaped pre-assembly gap 311, the space at the upper end of the U-shaped gap can prevent the liquid absorbing cotton 41 from being shaken out during installation to reduce the generation of product failure rate. Meanwhile, to further ensure the liquid inlet rate, the end of the pressing arm 11 is provided with a pressing head 111. The end of the pressing head 111 protrudes in an n shape or a semicircle. When the pressing head 111 is inserted into the pre-assembly gap 311, the pre-assembly gap 311 and the end of the pressing head 111 form an o-shaped liquid passage 32, and the liquid absorbing section 411 is pressed in the liquid passage 32. During installation, the intersection of the pressing arm 11 and the pressing head 111 is positioned against the end surface of the support arm 31 to ensure the pressing distance of the pressing head 111, thereby accurately limiting the area of the liquid passage 32 formed by the pre-assembly gap 311 and the pressing head 111 to ensure the liquid inlet rate and avoid the deviation of the liquid inlet rate to cause liquid leakage or dry taste. In addition, the inner hole surface of the o-shaped liquid passage 32 is an arc surface to ensure that the liquid absorbing cotton 41 completely fills the liquid passage 32 to avoid the liquid passage 32 having edges to cause the liquid absorbing cotton 41 to be incompletely filled and have gaps to cause liquid leakage.

[0050] Specifically, as shown in the figure, Figure 5As shown in this embodiment, the pressure head 111 is located above the liquid inlet 21, and the lower arc surface of the U-shaped pre-installed notch 311 is located below the liquid inlet 21, so that the diameter of the liquid passage 32 formed by the pressure head 111 and the pre-installed notch 311 is larger than the diameter of the liquid inlet 21, and the liquid absorption section 411 extends out of the liquid passage 32. When the base 30 is installed on the main body 20, the liquid inlet 21 is located in the area enclosed by the hole of the liquid passage 32, and the portion of the liquid absorption section 411 protruding outside the liquid passage 32 covers the liquid inlet 21, thereby sealing the liquid inlet 21 and ensuring that the solution entering from the liquid inlet 21 is absorbed by the liquid absorption cotton 41, effectively preventing leakage.

[0051] Furthermore, such as Figure 5 As shown in this embodiment, the diameter D of the inlet hole 21 is between 0.9 and 4 mm; the diameter d of the through hole 32 is between 1 and 5 mm, and the minimum value of the diameter difference X between the through hole 32 and the inlet hole 21 is 0.1 mm. That is, the absorbent cotton 41 filling the through hole 32 covers at least 0.05 mm of the inner edge of the inlet hole 21 to ensure effective sealing. In this embodiment, the diameter of the inlet hole 21 is 2.1 mm, and the diameter of the through hole 32 is 2.6 mm, meaning the absorbent cotton 41 covers 0.25 mm of the inner edge of the inlet hole 21, ensuring that the solution flowing in from the inlet hole 21 is completely absorbed by the absorbent cotton 41. The 0.25 mm allowance compensates for the deformation of the absorbent cotton 41 after absorbing the solution.

[0052] Furthermore, such as Figure 3 , Figure 5 and Figure 7 As shown in this embodiment, the outer wall of the support arm 31 is also provided with a relief groove 33. The relief groove 33 is located at the lower end of the pre-installation notch 311. The absorbent cotton 41 protrudes slightly from the liquid passage hole 32, for example, 0.1mm to 2mm. In this embodiment, both ends of the absorbent cotton 41 protrude 0.2mm from the two pre-installation notches 311. With the relief groove 33 provided, when inserted into the main body 20, the portion of the absorbent cotton 41 protruding from the pre-installation notch 311 can be slightly offset towards the relief groove 33 under force, preventing the phenomenon of product defects caused by hard installation.

[0053] Specifically, such as Figure 3 Combination Figure 8As shown, in the embodiment of the present application, the two side walls of the U-shaped preloading notch 311 are designed to be inclined and guided, so that the preloading notch 311 is designed to be gradually expanded, and the two side walls corresponding to the pressing head 111 are designed to be gradually expanded from the insertion front end to the insertion tail end. When the pressing head 111 is completely inserted into the preloading notch 311, the pressing head 111 is tightly fitted with the preloading notch 311. By designing the two side walls of the U-shaped preloading notch 311 to be inclined, the pressing head 111 is facilitated to be inserted, and at the same time, the time gap is matched with the initial insertion, which effectively facilitates installation, and at the same time, the tight fit is gradually increased with the increase of the insertion depth. Further effectively prompt the connection strength, prevent the whole vertical surface from being inserted into the tight fit, and cause the phenomenon of more inconvenient installation.

[0054] Specifically, as Figure 7 Combined Figure 8 As shown, in the embodiment of the present application, the upper end surfaces of the two side walls of the U-shaped preloading notch 311 of the support arm 31 are further provided with wedge-shaped blocks, and the two sides of the pressing arm 11 are provided with connecting grooves for inserting the wedge-shaped blocks. When the base 30 is inserted into the main body 20, the wedge-shaped blocks are inserted into the connecting grooves in a tight fit. By providing the wedge-shaped blocks on the upper end of the support arm 31 to be inserted into the connecting grooves provided on the two sides of the pressing arm 11, the connection stability is further enhanced, and at the same time, the insertion can be guided, and the installation accuracy is improved.

[0055] Specifically, as Figure 6 Combined Figure 2 As shown, in the embodiment of the present application, the outer diameter of the upper end of the main body 20 is smaller than the outer diameter of the lower end, so that the lower end has a larger atomization space while avoiding the product being too large as a whole. The cross section of the lower end of the main body 20 is elliptical, long circular track-shaped or polygonal. The elliptical shape or the long circular track shape includes a major axis and a minor axis, and the polygonal shape includes a long side and a short side. The upper end of the base 30 inserted into the main body 20 is adapted to the inner shape of the main body 20. The number of liquid inlet holes 21 is two, and the two liquid inlet holes 21 are located at the two ends of the major axis of the elliptical shape or the long circular track shape or at the two ends of the long side of the polygonal shape. By adopting the elliptical shape or the polygonal shape, the foolproof alignment installation is effectively realized, and at the same time, the liquid inlet holes 21 are arranged in the long side direction, so that the internal space is larger, and the phenomenon of heat concentration caused by the fact that the heat generating part 421 is close to the base 30 or the main body 20 is prevented.

So that when the condensed liquid drops on the baffle plate 13, it can slide down to the atomization cavity along the guide surface 131, avoiding gathering on the upper surface of the baffle plate 13, and causing the phenomenon of being directly sucked into the user's oral cavity during subsequent suction;

[0058] Further, as Figures 4 to 6 combined Figure 9 shown, in the embodiment of the present application, the air outlet 12 is further provided with a flexible sealing sleeve 14, and the middle hollow area of the flexible sealing sleeve 14 is provided for inserting the external air guide pipe 220.

At the same time, the connecting seat 34 is clearance-fitted with the inner wall of the mounting hole 310 to prevent the base 30 from being separated from the main body 20 due to excessive friction when the base 300 is disassembled, and to prevent the resistance from being too great when inserting.

[0064] It can be understood that, as Figure 2 As shown, in actual application, the base 300 and the shell 200 can be reversely buckled to be fixedly connected to form the disposable atomization device 1000, or can be over-dimensionally clamped by the outer wall of the silica gel sleeve 350 and the shell 200 to be detachably arranged, so as to facilitate replacement of the internal modular heating core assembly 100, which is not limited herein.

[0065] Further, the present application further provides an atomization device, which comprises a power supply device (not shown) and the atomization device 1000, and the atomization device 1000 is electrically connected with the power supply device when being mounted in the power supply device; when the power supply device supplies power to the atomization device 1000, the conductive electrode 340 and the conductive lead 422 provide current to the heating portion 421, so that the heating portion 421 generates heat to atomize the solution adsorbed by the atomization section 412 into an aerosol and then discharge the aerosol through the mist outlet 210.
