Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and in particular to an electronic atomization device. Background Art

[0002] Traditional electronic atomization devices usually include a power supply device and an atomizer, wherein the power supply device is used to supply power to the atomizer. The atomizer usually includes an oil cup with an opening at the bottom, an atomizer assembly disposed in the oil cup, and a base disposed at the opening at the bottom of the oil cup. An air outlet channel is disposed in the oil cup, and an air outlet is disposed at the top of the oil cup corresponding to the air outlet channel. The atomizer assembly, the inner wall of the oil cup, and the outer wall of the air outlet channel enclose a liquid storage chamber located in the oil cup and used to store atomized liquid. Specifically, the atomization assembly includes a bracket, an atomization core and an airway component, etc. The bracket, the atomization core and the airway component enclose an atomization channel connected to the air outlet channel. An air inlet connected to the atomization channel is provided on the base, and an oil inlet hole for connecting the liquid storage chamber and the atomization channel is provided on the bracket. The atomization core is located on the oil outlet side of the oil inlet hole. The atomization core includes an oil guide body and a heating body. The oil guide body is used to guide the atomized liquid on the oil outlet side of the oil inlet hole to the heating body, and the heating body is used to heat and atomize the atomized liquid to form an inhalable aerosol in the atomization channel leading to the air outlet channel.

[0003] In addition, a sealing structure is usually provided between the inner wall of the oil cup and the base. In order to ensure the sealing performance of the sealing structure, the sealing structure is usually interference fit with the inner wall of the oil cup, so that the inner wall of the oil cup will be subjected to the force of the sealing structure, which will cause the side wall of the oil cup to expand and deform outward. When the side wall of the oil cup expands and deforms outward, the reaction force of the inner wall of the oil cup on the sealing structure will be unbalanced, thereby reducing the reliability of the sealing structure, and causing the deformed part of the oil cup to leak easily. At the same time, the deformed oil cup will affect the overall appearance of the product. For this reason, the relevant technology proposes to cover the oil cup with a metal cover to prevent the side wall of the oil cup from expanding and deforming outward, but this method will increase the cost of the product.

[0036] Reference Figures 1 to 7 According to an embodiment of the present application, the electronic atomization device includes a shell 100, an atomization assembly and a base 200.

[0037] Specifically, the shell 100 is an internal hollow structure, and the shell 100 has an open end 110. The atomizer assembly is arranged in the shell 100 and close to the open end 110 of the shell 100. The base 200 is covered at the open end 110 of the shell 100. The base 200 is used to support and fix the atomizer assembly located in the shell 100, wherein an anti-deformation structure that is docked and matched along the axial direction of the shell 100 (the X direction in the accompanying drawings) is arranged between the base 200 and the open end 110 of the shell 100. The anti-deformation structure is used to improve the deformation resistance of the side wall of the shell 100 along the radial direction of the shell 100 (the direction perpendicular to the X direction). The cross-section of the open end 110 of the shell 100 is annular, and the cross-section of the open end 110 of the shell 100 has a short axis and a long axis that are perpendicular to each other. The two side walls of the shell 100 distributed along the short axis direction of the cross-section of its own open end 110 are provided with an anti-deformation structure between the base 200.

[0038] Reference Figure 4 It should be noted that the cross section of the opening end 110 of the housing 100 is similar to an ellipse, wherein the short axis direction of the cross section of the opening end 110 of the housing 100 is the Y direction in the drawings, and the long axis direction of the cross section of the opening end 110 of the housing 100 is the Z direction in the drawings. Of course, the cross section of the opening end 110 of the housing 100 may also be a rectangle (non-square) or other polygon with a short axis and a long axis perpendicular to each other, which is not limited here.

[0039] When in use, since an anti-deformation structure is provided between the shell 100 and the base 200, it is helpful to reduce the situation where the side wall of the shell 100 expands outward and deforms, and there is no need to provide a metal cover in the related art, which is helpful to reduce the cost of the product. Among them, the two side walls of the shell 100 distributed along the short axis direction of the cross section of its own open end 110 are provided with an anti-deformation structure between the base 200, that is, at least the anti-deformation ability of the two side walls of the shell 100 with a larger span along the radial direction of the shell 100 can be improved.

[0040] Reference Figure 1 , Figure 2 and Figure 5In some embodiments, the anti-deformation structure includes a protrusion 111 and a groove 210 matched with the protrusion 111, and one of the open end 110 of the housing 100 and the base 200 is provided with the protrusion 111, and the other is provided with the groove 210. The protrusion 111 and the groove 210 connected to each other can limit the outward expansion and deformation of the side wall of the housing 100, thereby improving the anti-deformation ability of the side wall of the housing 100 along the radial direction of the housing 100, and further reducing the situation of the outward expansion and deformation of the side wall of the housing 100.

[0041] Specifically, the protrusion 111 is disposed at the open end 110 of the shell 100, and the groove 210 is disposed on the base 200. Of course, the protrusion 111 can also be disposed on the base 200, and correspondingly, the groove 210 is disposed at the open end 110 of the shell 100, which is not limited here.

[0042] Reference Figure 2 , Figure 5 and Figure 7 In some embodiments, the protrusion 111 is integrally formed at the opening end 110 of the shell 100 , and the protrusion 111 extends along the axial direction of the shell 100 and protrudes from the end surface of the opening end 110 of the shell 100 , and its structure is simple and easy to implement.

[0043] It should be noted that in some of the embodiments, the open end 110 of the housing 100 is provided with a plurality of protrusions 111 spaced apart along the circumference of the housing 100, and correspondingly, the base 200 is provided with a plurality of grooves 210 corresponding to the plurality of protrusions 111. Of course, the grooves 210 may also be annular grooves, in which case only one groove 210 is required, and no limitation is made here. By providing a plurality of protrusions 111 spaced apart along the circumference of the housing 100 at the open end 110 of the housing 100, the restriction on the side wall of the housing 100 can be enhanced, thereby further improving the ability of the side wall of the housing 100 to resist deformation along the radial direction of the housing 100.

[0044] The inventors of the present application discovered during the implementation of the present application that if an annular protrusion and an annular groove are matched, since the annular protrusion and the annular groove between the base 200 and the open end 110 of the shell 100 are matched before the atomizer assembly has been pre-assembled in the shell 100, the side wall of the shell 100 has expanded and deformed outward. In addition, if there is also a seal between the outer circumferential wall of the base 200 and the inner circumferential wall of the shell 100, the deformation of the side wall of the shell 100 along the radial direction of the shell 100 will be further increased. Therefore, if the anti-deformation structure is matched with an annular protrusion and an annular groove, the assembly difficulty between the shell 100 and the base 200 will increase, and even additional auxiliary tools may be required for assembly. To solve the above problem, the inventors tried to reduce the matching size of the protrusion 111 and increase the matching size of the groove 210, that is, a clearance match is adopted between the protrusion 111 and the groove 210, but this will cause the anti-deformation ability of the anti-deformation structure to be weakened. When trying to further solve the above problem, the inventors found that by setting an anti-deformation structure between the two side walls distributed along the short axis direction of the cross-section of the open end 110 of the shell 100 and the corresponding area of ​​the base 200 (the anti-deformation structure is only set locally), for example, by setting the protrusion 111 to a non-closed annular local protrusion structure that protrudes from the end face of the open end 110 of the shell 100 along the axial direction of the shell 100, and setting the protrusions 111 respectively on the two side walls distributed along the short axis direction of the cross-section of the open end 110 of the shell 100, it is possible to ensure the anti-deformation ability of the anti-deformation structure and solve the problem of assembly difficulty between the shell 100 and the base 200 when using an annular protrusion and an annular groove.

[0045] Reference Figure 4 and Figure 7 In some embodiments, the two side walls of the shell 100 distributed along the short axis direction of the cross section of the open end 110 thereof have a thin-walled area a and a thick-walled area b along the circumference of the shell 100, the wall thickness T of the thick-walled area b is greater than the wall thickness T of the thin-walled area a, and at least part of the protrusions are arranged corresponding to the thin-walled area a. The thin-walled area a of the shell 100 is easy to deform, and the protrusions 111 cooperating with the grooves 210 are arranged for the thin-walled area a of the shell 100, which can improve the anti-deformation ability of the thin-walled area a of the shell 100 along the radial direction of the shell 100, thereby effectively limiting the outward expansion and deformation of the side wall of the shell 100.

[0046] Reference Figure 6 and Figure 7In some embodiments, the maximum width W of the protrusion 111 is greater than the maximum thickness D of the protrusion 111, and the maximum length H of the end surface of the protrusion 111 protruding from the open end 110 of the housing 100 is less than or equal to the maximum width W of the protrusion 111, thereby improving the structural strength of the protrusion 111 and facilitating improving the reliability and stability of the protrusion 111. The width direction of the protrusion 111 is the direction shown by the maximum width W of the protrusion 111 in the accompanying drawings, and the length direction of the protrusion 111 is the direction shown by the maximum length H of the end surface of the protrusion 111 protruding from the open end 110 of the housing 100 in the accompanying drawings. The length direction of the protrusion 111 is parallel to the axial direction of the housing 100.

[0047] It should be noted that in some embodiments, the thickness of the protrusion 111 increases from both ends to the middle along the circumference of the housing 100 to increase the deformation resistance of the protrusion 111. Specifically, the thickness direction of the protrusion 111 is the direction shown by the maximum thickness D of the protrusion 111 in the drawings.

[0048] It should be noted that in some of the embodiments, the outer contour shape of the cross section of the protrusion 111 along its own length direction is one of a rectangle, a triangle, a trapezoid, a semicircle, and a fan. Of course, the outer contour shape of the cross section of the protrusion 111 along its own length direction can also be other shapes, which is not limited here.

[0049] It should be noted that, in some of the embodiments, the thickness of the end of the protrusion 111 close to the shell 100 is greater than the thickness of the end of the protrusion 111 away from the shell 100, thereby improving the structural strength of the protrusion 111, which is beneficial to preventing the connection between the protrusion 111 and the shell 100 from breaking when subjected to radial shear force along the shell 100, thereby helping to improve the reliability and stability of the protrusion 111. In addition, in the axial direction of the shell 100, the end of the protrusion 111 with a smaller wall thickness D (i.e., the end of the protrusion 111 away from the shell 100) can form an inclined guide surface to reduce the difficulty of assembly, thereby facilitating the insertion of the protrusion 111 into the groove 210.

[0050] Reference Figure 4 In some of the embodiments, the wall thickness of the two side walls of the shell 100 distributed along the short axis direction of the cross-section of the open end 110 of the shell 100 increases from both ends to the middle along the long axis direction of the cross-section of the open end 110 of the shell 100, thereby enhancing the deformation resistance of the middle position of the two side walls with larger spans of the shell 100.

[0051] It should be noted that, in some of the embodiments, the base 200 is at least partially located in the open end 110 of the shell 100 and is interference fit with the inner side wall of the shell 100, wherein the base 200 is located between the outer side wall in the open end 110 of the shell 100 and the inner side wall of the shell 100, and the interference fit amount in the short axis direction of the cross section of the open end 110 of the shell 100 is smaller than the interference fit amount in the long axis direction of the cross section of the open end 110 of the shell 100. The two side walls are more susceptible to deformation than the two side walls distributed along the long axis direction of the cross section of the opening end 110 of the shell 100. Thus, the interference fit between the two side walls distributed along the long axis direction of the cross section of the opening end 110 of the shell 100 and the base 200 can form a pulling force that makes the two side walls distributed along the short axis direction of the cross section of the opening end 110 of the shell 100 move closer to the central axis of the shell 100, thereby resisting the outward expansion and deformation of the two side walls distributed along the short axis direction of the cross section of the opening end 110 of the shell 100.

[0052] Reference Figure 1 and Figure 5 In some embodiments, the atomizer assembly includes a flexible bracket 310, an atomizer core 320, and a fixing member 330. The flexible bracket 310 is fixedly arranged in the housing 100 and enclosed with the housing 100 to form a liquid storage chamber 400 for storing atomized liquid. A mounting groove 311 for accommodating the atomizer core 320 and the fixing member 330 is provided on one side of the flexible bracket 310. The fixing member 330 is embedded in the mounting groove 311 and presses and fixes the atomizer core 320 in the mounting groove 311. Specifically, the fixing member 330 and the mounting groove 311 are interference fit, and the atomizer core 320 is fluidically connected to the liquid storage chamber 400. The base 200 is supported on one end of the flexible bracket 310 facing the open end 110 of the housing 100. Specifically, as a flexible structure, the flexible bracket 310 can be deformed when subjected to force, which is convenient for installing the atomizer core 320 and the fixing member 330, and is conducive to reducing the requirements of the relevant structure for processing accuracy, specifically referring to the tolerance aspect. In addition, as a flexible structure, the flexible bracket 310 has a certain elasticity, and can be used as a bracket to install the atomizer core 320 and the fixing member 330, and can also be used as a seal, thereby reducing the number of seals.

[0053] Reference Figure 3 and Figure 5 In some embodiments, a convex rib 312 for sealing is provided on the outer peripheral surface of one end of the flexible bracket 310 facing the open end 110 of the shell 100 , and the convex rib 312 abuts against the inner wall of the shell 100 and has an interference fit with the inner wall of the shell 100 .

[0054] It should be noted that in some embodiments, the fixing member 330 is a hard insulator so that the fixing member 330 can improve the anti-deformation ability of the flexible bracket 310. Specifically, since the flexible bracket 310 is a soft structure, the fixing member 330 has a supporting function when it adopts a hard structure, which can improve the overall structural strength of the flexible bracket 310 and the fixing member 330 after they are connected together, and can avoid the problem of deformation and leakage at the connection point of the two due to the fact that both are flexible structures. Of course, the fixing member 330 can also be made of a flexible material, which is not limited here.

[0055] It should be noted that, in some of the embodiments, the first surface of the fixing member 330 facing the opening of the mounting groove 311 (i.e., the side facing away from the atomizer core 320) is flush with or lower than the second surface of the flexible bracket 310 where the opening of the mounting groove 311 is located, so as to avoid the fixing member 330 protruding from the second surface at the opening of the mounting groove 311 and exerting an extrusion effect on the inner wall of the shell 100, causing the side wall of the shell 100 to expand and deform outward, and even affecting the sealing between the flexible bracket 310 and the shell 100 and causing leakage.

[0056] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, an air outlet channel 120 is provided in the shell 100, and a suction port 130 connected to the air outlet channel 120 is provided at one end of the shell 100 away from its own open end 110. The flexible bracket 310, the inner wall of the shell 100 and the outer wall of the air outlet channel 120 are enclosed to form a liquid storage chamber 400, and an atomization groove 331 is provided on the side of the fixing member 330 facing the atomization core 320, so that the fixing member 330, the atomization core 320 and the flexible bracket 310 are enclosed to form an atomization channel 500, and the flexible bracket 310 has a An oil inlet 313 is connected to the liquid storage chamber 400 and the mounting groove 311, and the atomizer core 320 is arranged in the mounting groove 311 and is located on the oil outlet side of the oil inlet 313. The end of the flexible bracket 310 facing the open end 110 of the shell 100 is provided with a first air inlet 314 connected to the atomization channel 500, and the end of the flexible bracket 310 facing away from the open end 110 of the shell 100 is provided with an air outlet 315 connecting the atomization channel 500 and the air outlet channel 120. The base 200 is provided with a second air inlet 220 connected to the first air inlet 314.

[0057] Specifically, the atomization core 320 includes an oil guide body 321 and a heating body 322. The oil guide body 321 has a liquid absorption surface and an atomization surface. The liquid absorption surface of the oil guide body 321 faces the oil inlet hole 313, and the atomization surface of the oil guide body 321 faces the atomization groove 331. The heating body 322 is arranged on the atomization surface of the oil guide body 321. The oil guide body 321 is used to guide the atomized liquid on the oil outlet side of the oil inlet hole 313 to the heating body 322. The heating body 322 is used to heat and atomize the atomized liquid to form an inhalable aerosol in the atomization channel 500 that leads to the air outlet channel 120.
