[0002] The electronic atomization equipment comprises an atomization device and a power supply device for supplying power to the atomization device. 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 for discharge. In the mainstream heating core assemblies on the market, the liquid absorbing 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 weak compared with the cotton material. The existing heating core on the market usually directly winds the heating wire around the cotton material, wraps the heating net or contacts the heating piece to form the heating core assembly for delivery. Due to the differences in processing technology and processing environment of downstream manufacturers, the compatibility is poor, and the cotton material is easily contaminated during transportation. Therefore, the cotton heating core assembly with good taste cannot be modularized and popularized in the industry. SUMMARY

[0044] Please refer to Figures 1 to 6The 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 an 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.

[0045] Specifically, as shown in the drawings, Figure 3 Combined with Figure 4 In the embodiment of the present application, the heating core assembly 100 comprises a heating core 40, the heating core 40 comprising 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 part 421 for heating under the action of current, the heating part 421 can adopt a nichrome heating wire, a steel mesh, a perforated steel pipe or a ceramic heating sheet, and in the embodiment, a nichrome heating wire is selected and wound in the middle part of the liquid absorbing cotton 41, so that an atomization section 412 is formed in the middle part of the liquid absorbing cotton 41.

[0046] The base 30 is constructed to provide support for the heating core 40, and the two ends of the liquid absorbing cotton 41 are arranged on the base 30 to form a liquid absorbing section 411, and the middle part of the liquid absorbing cotton 41 is suspended to form the atomization section 412; the lower end of the base 30 is provided with a support rim 35, and the end face of the lower end is provided with an air inlet 36;

[0047] The outer pipe 20 is made of a steel pipe, and the lower end of the outer pipe 20 is sleeved on the base 30, the end face of the lower end of the outer pipe 20 abuts against the support rim 35 for limiting, and the side wall of the outer pipe 20 is provided with a liquid inlet hole 21, so that the solution flowing into the liquid inlet hole 21 can be absorbed by the liquid absorbing cotton 41.

[0048] The gland 10 is inserted into the upper end of the outer pipe 20, and the two ends of the liquid absorbing cotton 41, i.e. the liquid absorbing section 411, are pressed and held on the base 30, so as to prevent the liquid absorbing cotton 41 from shaking, and at the same time, the atomization section 412 of the liquid absorbing cotton 41 is suspended at a predetermined position, avoiding the heating part 421 wound on the atomization section 412 from being deviated and contacting the inner wall of the base 30, which causes the phenomenon of burning during work, the upper end of the gland 10 is provided with an air outlet 12, so that the gas mist generated by the atomization section 412 after being heated and atomized can be discharged.

[0049] The atomization gas path comprises an air inlet path between the air inlet 36 and the atomization section 412, an air outlet path between the atomization section 412 and the air outlet 12, and an atomization cavity where the atomization section 412 is located.

[0050] The application has the advantages that the base 30 provides a mounting carrier for the liquid absorbing cotton 41 and the heating element 42, and the liquid absorbing cotton 41 is tightly pressed against the base 30 by the sleeve pipe 20 and the cover 10 to form a package, so that the package is not contaminated when being transported to a downstream factory or a downstream station. After the package is formed, the liquid absorbing cotton 41 and the heating element 42 are located in the cover 10 and the base 30 and are not deformed, so that the liquid absorbing cotton 41 and the heating element 42 are not damaged by the production process and the production environment of the downstream factory, and the taste stability of the product is not poor. After being independently packaged, the heating core assembly 100 module is formed, and the standard part is formed. The appearance of the atomization device 1000 is changed, and only the position of the heating core assembly 100 needs to be reserved in the atomization device 1000, so that each product does not need to be re-adjusted.

[0051] Specifically, as Figure 3 Combined Figure 5 shown, in the embodiment of the application, in order to ensure a large atomization cavity and avoid the heating part 421 from contacting the base 30, in the embodiment, the two sides of the upper end of the base 30 are provided with support arms 31, and the space between the two spaced support arms 31 forms the atomization cavity together with the inner wall of the outer pipe 20 and the cover 10. The upper end surface of the support arm 31 is provided with a pre-installation notch 311 for mounting the liquid absorbing cotton 41, and the part of the cover 10 inserted into the outer pipe 20 tightly presses the liquid absorbing cotton 41 in the pre-installation notch 311. Therefore, the liquid absorbing cotton 41 is arranged between the two support arms 31. In order to facilitate processing and production, the two pre-installation notches 311 are arranged opposite to each other, and when being installed, only the two ends of the liquid absorbing cotton with the heating part wound thereon need to be pre-placed in the two pre-installation notches. The two pre-installation notches 311 are hollowed out towards the surface of the outer pipe 20, and the side wall of the support arm 31 is exposed. The liquid absorbing part at the two ends of the liquid absorbing cotton 41 passes through the pre-installation notch 311 and is exposed to the outer side wall of the support arm 31. When the outer pipe is sleeved, the part of the liquid absorbing cotton protruding from the outer side wall of the support arm has a force with the outer pipe, so that the liquid absorbing cotton can be effectively fixed in the pre-installation notch and prevent the liquid absorbing cotton from shaking before being pressed into the cover.

[0052] Further, as Figure 3As shown in this embodiment, to ensure that the pressure cap 10 presses the absorbent section 411 into the pre-installed notch 311 while ensuring the liquid inlet rate, in this embodiment, the lower end of the pressure cap 10 is provided with two pressure-holding arms 11 corresponding to the two support arms 31, and the protruding ends of the two pressure-holding arms 11 are provided with pressure-holding heads 111. The two pressure-holding arms 11 respectively abut and limit the upper ends of the two support arms 31, and the two pressure-holding heads 111 are inserted into the two pre-installed notches 311 to press the two ends of the absorbent cotton 41 into the two pre-installed notches 311 respectively. By positioning with the pressure-holding arms 11 and then pressing with the pressure-holding heads 111, it is ensured that the cotton is pressed to the designated position. At the same time, the space between the pre-installed notch 311 and the pressure-holding heads 111 can be precisely limited to control the liquid inlet rate.

[0053] Specifically, such as Figure 3 As shown in this embodiment, the pre-installed notch 311 is U-shaped, and the protruding end of the pressing head 111 is n-shaped. When the pressing head 111 is inserted into the U-shaped pre-installed notch 311, an O-shaped liquid passage hole 32 is formed, and the absorbent cotton 41 is pressed into the liquid passage hole 32. The inner surface of the O-shaped liquid passage hole 32 is all arc surface to ensure that the absorbent cotton 41 completely fills the liquid passage hole 32, avoiding the phenomenon that the liquid passage hole 32 has sharp corners, which may cause the absorbent cotton 41 to not be completely filled and have gaps, resulting in leakage.

[0054] Specifically, such as Figure 4 As shown in this embodiment, the inlet hole 21 and the outlet hole 32 of the outer tube 20 are directly opposite each other, and the size of the outlet hole 32 is larger than the size of the inlet hole 21, so that the edge of the inlet hole 21 facing the outlet hole 32 is located within the edge of the outlet hole 32. An absorbent cotton 41 protruding from the outlet hole 32 covers the edge of the inlet hole 21 facing the outlet hole 32, thereby sealing the inlet hole 21 and ensuring that all solution entering through the inlet hole 21 is absorbed by the absorbent cotton, effectively preventing leakage.

[0055] Furthermore, such as Figure 4 As shown in this embodiment, the base 30 is provided with a relief groove 33 on the side facing the outer tube 20. 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, by 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 the outer tube 20 is sleeved and the pressure cap 10 is pressed in, the part protruding from the pre-installation notch 311 can be slightly deflected towards the relief groove 33 to prevent the product from being defective due to hard installation.

[0056] Furthermore, such as Figure 4As shown, in the embodiment of the present application, the diameter D of the liquid inlet hole 21 is between 0.9 mm and 4 mm; the diameter d of the liquid passing hole 32 is between 1 mm and 5 mm, and the minimum value of the diameter difference X between the liquid passing hole 32 and the liquid inlet hole 21 is 0.1 mm, that is, the liquid absorbing cotton 41 filling the liquid passing hole 32 covers the inner side edge of the liquid inlet hole 21 by at least 0.05 mm, ensuring effective sealing. In the embodiment, the diameter of the liquid inlet hole 21 is 2.1 mm, and the diameter of the liquid passing hole 32 is 2.6 mm, that is, the liquid absorbing cotton 41 covers the inner side hole edge of the liquid inlet hole 21 by 0.25 mm, ensuring that the solution flowing into the liquid inlet hole 21 is completely absorbed by the liquid absorbing cotton 41. At the same time, reserving 0.25 mm can compensate for the deformation amount of the liquid absorbing cotton 41 after absorbing the solution.

[0057] Specifically, as shown in Figure 3 As shown, in the embodiment of the present application, the cross section of the outer tube 20 is oval, long circular track-shaped or polygonal, the oval or the long circular track-shaped includes a major axis and a minor axis, the polygonal includes a long side and a short side, the part of the base 30 and the gland 10 inserted into the outer tube 20 is adapted to the inner shape of the outer tube 20, the number of the 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 oval or the long circular track-shaped or at the two ends of the long side of the polygonal. By adopting the oval or polygonal shape, 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 gland 10 is prevented. At the same time, through the support arm 31 and the pressing arm 11, the gland 10 and the base 30 are arranged at intervals and surrounded by the outer tube 20 to form an atomization cavity, the positions on both sides of the atomization section 412 of the liquid absorbing cotton 41 are hollowed out and surrounded by the outer tube 20, so that the space is larger, and the phenomenon of heat concentration caused by the fact that the heat generating part 421 winding around the atomization section 412 is close to the base 30 or the gland 10 is effectively avoided.

[0058] Specifically, as shown in Figure 3 In combination with Figure 4As shown in the embodiment of the present application, the base 30 is inserted into the front end of the outer tube 20 and fits with the inner wall of the outer tube 20 in clearance fit, and the base 30 is inserted into the tail end of the outer tube 20 and fits with the inner wall of the outer tube 20 in interference fit (see the interference fit area marked Q), and the interference amount is 0.01-0.1 mm; the gland 10 is inserted into the front end of the outer tube 20 and fits with the inner wall of the outer tube 20 in clearance fit, and the gland 10 is inserted into the tail end of the outer tube 20 and fits with the inner wall of the outer tube 20 in interference fit, and the interference amount is 0.01-0.1 mm. In the embodiment, the base 30 and the gland 10 are inserted into the front end of the outer tube 20 and fit with the outer tube 20 in clearance fit, and then sealed by the inserted tail end in interference fit, and the interference amount is 0.02 mm, which is effective for installation and prevents the solution from leaking out of the gap between the outer peripheral surface of the base 30, the outer peripheral surface of the gland 10 and the inner wall of the outer tube 20. At the same time, the interference amount is prevented from being too large to cause the outer tube 20 to be deformed. At the same time, the interference fit is used without the need to install sealing silica gel, which reduces the installation process, and the tail end is inserted for sealing, which avoids the whole surface interference fit, which requires high machining precision and is prone to cause product defects.

[0059] Specifically, as Figure 4 shown in the embodiment of the present application, the depth value S of the base 30 inserted into the outer tube 20 in interference fit is 1 mm-5 mm, and the depth value s of the gland 10 inserted into the outer tube 20 in interference fit is 1 mm-5 mm, and in the embodiment, the depth S=s=1.5 mm of the interference insertion is used to ensure the insertion depth, prevent the base 30 and the gland 10 from separating from the outer tube 20 when falling, and prevent the insertion from being too deep to cause the outer tube 20 to be deformed and expand outward.

[0060] Further, as Figure 4 combined with Figure 5As shown in the embodiment of the present application, the air outlet gas path is further provided with a baffle 13, which is formed by one of the two pressing arms 11 or the middle part of the two pressing arms 11 and horizontally arranged in the air outlet gas path. The baffle 13 covers at least the part of the air outlet 12 that is opposite to the atomization section 412. The two sides of the baffle 13 and the inner wall of the air outlet gas path form air passing channels 133. The air flow from the air inlet 36 passes through the atomization section 412, the air passing channels 133 and the air outlet gas path and then flows out from the air outlet 12. By arranging the baffle 13 to cover the air outlet 12, the falling of dust and fibers from the outside to the atomization section 412 is effectively prevented, the generation of odor during atomization is avoided, the phenomenon of oil explosion of the condensed liquid mixed solution during heating and atomization is prevented, and the user's discomfort during suction is avoided due to the splashing of the hot solution from the air outlet 12. At the same time, the baffle 13 is formed by the middle part of the two pressing arms 11, which effectively strengthens the connection strength of the pressing arms 11 and prevents the phenomenon of large deformation during pressing.

[0061] Specifically, as shown in Figure 5 In the embodiment of the present application, the side of the baffle 13 that is close to the air outlet 12, i.e. the upper surface of the baffle 13, is provided with a guide surface 131, and the lower surface is a blocking surface that is parallel to the atomization section 412. The higher end of the guide surface 131 is close to the air outlet 12, and the lower end is away from the air outlet 12. The guide surface 131 can be a slope, a taper, an arc surface, etc., which is not limited here. When the condensed liquid drops on the baffle 13, it can slide along the guide surface 131 into the atomization cavity, avoiding accumulation on the upper surface of the baffle 13 and the subsequent phenomenon of being directly sucked into the user's oral cavity during suction.

[0062] Specifically, as shown in Figure 5 In the embodiment of the present application, the side wall of the baffle 13 that forms the air passing channel 133 is formed with an arc surface transition to form a gas guiding surface 132, so as to guide the air flow of the atomization section 412 to the air outlet gas path, thereby making the air flow more smooth.

[0063] Specifically, as shown in Figure 4As shown, in the embodiment of the present application, the air outlet 12 is further sleeved with a flexible sealing sleeve 14, and a middle hollow area of the flexible sealing sleeve 14 is used for inserting an external air guide pipe 220, so as to improve the smoothness and sealing performance of the heating core assembly 100 as a modular component in connecting with the air guide structure of the external atomization device 1000.
