Description

[Technical Field]

[0001] The present invention relates to the field of electronic cigarette technology, and more particularly to a rechargeable electronic cigarette case. [Background technology]

[0002] E-cigarettes are a non-combustible alternative to tobacco. They share some characteristics with regular cigarettes, allowing smokers to feel refreshed and satisfied with the pleasure and long-standing smoking habits they experience. However, they are fundamentally different from regular cigarettes. E-cigarettes do not burn, contain no tar, and do not contain the 460 or so chemicals that cause respiratory and cardiovascular diseases produced by regular cigarettes during combustion. Therefore, apart from the carcinogens found in regular cigarettes, they do not pose any harm to others or cause environmental pollution from "environmental tobacco smoke."

[0003] Regarding electronic cigarettes, publication number CN217826764U discloses a rechargeable, large-capacity, leak-proof, disposable electronic cigarette, which specifically discloses a case, with an atomizer module and a battery module connected to the top and bottom of the case, respectively; the atomizer module includes a case, with a hanging plate attached to the outer top of the case, with a string hanging hole opened inside the hanging plate, an oil cup tube installed inside the case, with a cigarette silicone and a heating wire silicone engaged and connected to the top and bottom of the oil cup tube, respectively, and two symmetrical exhaust pressure relief grooves opened inside the cigarette silicone; the battery module includes a bottom cover, with a battery installed inside the bottom cover, a TYPE-C charging interface provided on the outside of the bottom cover, and a gas regulating switch provided at the bottom of the bottom cover.

[0004] However, in the above-mentioned rechargeable, large-capacity, leak-proof disposable electronic cigarette, the atomizer module and battery module are connected to the case, and thus a three-tiered structure including the case, the case over the atomizer module, and the bottom cover over the battery module form a complete case body. However, in actual use, the case body consisting of the case, housing, and bottom cover may fall off if the electronic cigarette is dropped. In other words, because the case body of the electronic cigarette is not strong and durable, if the case body is severely damaged by a drop, the electronic cigarette may become unusable. Therefore, improvements to the prior art are required. Summary of the Invention [Problem to be solved by the invention]

[0005] In response to the problems in the prior art described above, the object of the present invention is to provide a highly practical rechargeable electronic cigarette case that uses an integrally molded metal case body so that the case body will not fall off if the electronic cigarette is dropped, making it stronger, more durable, and able to guarantee the service life of the electronic cigarette to a certain extent; it also solves other problems in the prior art. [Means for solving the problem]

[0006] To achieve the above objectives, the technical proposal of the present invention is as follows: A rechargeable electronic cigarette case includes a single-piece, molded metal case body; the case body has a vertically extending shape; an installation cavity is provided inside the case body, and a top cover installation port is provided at the top; the shape of the case body is formed by multiple press stretching processes, and a bottom cover installation groove and a protrusion that protrudes into the installation cavity are respectively formed at the middle position of the bottom of the case body by upward reverse pressing, and a charging hole and a screw positioning hole that penetrate vertically are respectively formed at the bottom surface of the bottom cover installation groove, and the protrusions increase the tensile strength of the screw positioning hole and the stability after the charging cable is inserted into the charging hole; a switch and an electric quantity display hole that penetrate horizontally are further provided on the side wall of the case body; and The wall thickness is 0.6mm-1mm, and the thickness from the top of the protrusion to the bottom of the case body is 2mm-3mm, which ensures the overall strength of the case body; the peripheral outer walls of the case body all have the arc-shaped outer protrusions, which improves the gripping feel of the case body; the cross-sectional area of ​​the bottom of the case body is smaller than that of the rest of the case body, and an arc-shaped transition is formed between the lower ends of the side walls of the case body and the bottom surface of the case body, which provides a cushioning effect when the case body is dropped and makes the case body less likely to be damaged; the case body is made of a single piece of metal, which prevents it from falling off or being damaged when dropped.

[0007] It also includes technical proposals such as: Furthermore, the side wall thickness of the case body is 0.8 mm; the thickness between the top surface of the protrusion and the bottom surface of the case body is 2.65 mm, thereby ensuring the strength of the case body.

[0008] Furthermore, the maximum distance between the opposing side walls of the case body is smaller than the maximum distance between the opposing side walls of other cases, allowing the overall shape of the case body to be similar to a flat shape.

[0009] Furthermore, the dimensions of the bottom cover mounting groove can be enlarged by grinding the peripheral side wall, thereby providing the bottom cover mounting groove with sufficient dimensions to stably mount the bottom cover.

[0010] Furthermore, the bottom cover mounting groove is oval in shape, which prevents the bottom cover from swinging to either side after mounting is complete.

[0011] Furthermore, an annular relief groove is provided around the bottom surface of the mounting cavity.

[0012] Furthermore, the case body is made of aluminum. [Effects of the Invention]

[0013] The beneficial effects of the present invention are as follows: (1) The present invention uses a one-piece molded metal case body, which will not fall off if the electronic cigarette is dropped. This makes the case body stronger and more durable than the conventional three-section case body, and can ensure the service life of the electronic cigarette to a certain extent. (2) In this invention, the sidewall thickness of the case body is set to 0.6mm-1mm, and the thickness from the top of the protrusion to the bottom of the case body is set to 2mm-3mm, thereby ensuring the overall strength of the case body and making it less likely to burst; further, because the protrusion is formed by reverse pressing, the thickness from the top of the protrusion to the bottom of the bottom cover mounting groove is approximately the same as the thickness from the bottom of the protrusion to the bottom of the case body, allowing the hole to be drilled with a sufficient thickness from the top of the protrusion to the bottom of the bottom cover mounting groove, preventing the punched hole from being easily broken or difficult to use due to its depth. For example, after drilling the charging hole and screw positioning hole corresponding to the position of the bottom cover mounting groove, the thickness from the top of the protrusion to the bottom of the bottom cover mounting groove is sufficient, so the installation of the protrusion increases the tensile strength of the screw positioning hole, making the sidewall of the screw positioning hole less likely to burst, and also reducing the likelihood of the charging cable shaking after insertion into the charging hole, thereby improving the stability of the charging cable. (3) The case body of the present invention, whose peripheral outer wall has an arcuate surface of an external protrusion, improves the gripping feel of the case body, that is, the case body can be gripped more comfortably. (4) The cross-sectional area of ​​the lower end of the side wall of the case body of the present invention gradually decreases toward the bottom, forming an arc-shaped transition. This allows the arc-shaped transition to have a greater cushioning effect when the case body is dropped than when it is positioned at a right angle, and also improves the impact resistance of the case body, making it less likely for the product to be damaged when dropped. (5) The present invention provides a bottom cover mounting groove, which allows for convenient installation of the bottom cover. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Specific embodiments of the present disclosure will be described below with reference to the drawings.

[0016] As shown in Figures 1 to 5, this rechargeable electronic cigarette case includes a metal case body 1 that is molded in one piece; the case body 1 has a shape that extends in the vertical direction; an attachment cavity 2 is provided inside the case body 1, and a top cover attachment port 3 is provided at the top; the shape of the case body 1 is formed by multiple press stretching processes, and a corresponding bottom cover attachment groove 9 and a protrusion 11 that protrudes into the attachment cavity are formed at the middle position of the bottom of the case body 1 by upward reverse pressing, and a charging hole 4 and a screw positioning hole 5 that penetrate vertically are provided at the bottom surface of the bottom cover attachment groove 9, and the protrusion 11 improves the tensile strength of the screw positioning hole 5 and prevents the charging cable from being inserted into the charging hole 4. The side wall of the case body 1 is further provided with a switch and electric quantity display hole 6 penetrating laterally; the side wall thickness T1 of the case body 1 is 0.6mm-1mm, and the thickness T2 from the top of the protrusion 11 to the bottom of the case body is 2mm-3mm; the surrounding outer wall of the case body 1 all forms an arc-shaped outer protrusion; the cross-sectional area of ​​the bottom of the case body 1 is smaller than that of the rest of the case body 1, and the cross-sectional area of ​​the lower end of the side wall of the case body 1 gradually decreases toward the bottom, so as to form an arc-shaped transition from the lower end of the side wall to the bottom of the case body; the one-piece molded metal case body 1 can be prevented from falling off or being damaged when dropped. [Example]

[0017] Therefore, the above-mentioned one-piece metal case body 1 prevents the case body 1 from falling off when the electronic cigarette is dropped, and the case body 1 is stronger and more durable than the conventional three-stage case body, ensuring the service life of the electronic cigarette to a certain extent; by setting the side wall thickness T1 of the case body 1 to 0.6mm-1mm and the thickness T2 from the top of the protrusion 11 to the bottom of the case body 1 to 2mm-3mm, the overall strength of the case body 1 can be ensured and it can be made less likely to burst; furthermore, because the protrusion 11 is formed by reverse pressing, the thickness T3 from the top of this protrusion 11 to the bottom of the bottom cover mounting groove 9 is approximately the same as the thickness T4 from the bottom of the protrusion 11 to the bottom of the case body 1, so that the thickness T3 from the top of the protrusion 11 to the bottom of the bottom cover mounting groove 9 can be made thick enough to drill a hole, and the punched hole will not be easily broken due to its depth, etc. This prevents awkwardness during use. For example, after drilling the charging port 4 and the screw positioning hole 5 corresponding to the position of the bottom cover mounting groove 9, the thickness between the top of the protrusion 11 and the bottom of the bottom cover mounting groove 9 is sufficient. Therefore, the placement of the protrusion 11 increases the tensile strength of the screw positioning hole 5, making the side wall of the screw positioning hole 5 less likely to rupture and reducing the likelihood of the charging cable swinging after being inserted into the charging port 4, thereby improving the stability of the charging cable. The case body 1, whose outer peripheral wall has an arc-shaped outer protrusion, improves the gripping feel of the case body 1. The arrangement in which the cross-sectional area of ​​the lower end of the side wall of the case body 1 gradually decreases toward the bottom creates an arc-shaped transition, which provides a better cushioning effect when the case body 1 is dropped than a right-angled transition, improving the impact resistance of the case body 1 and reducing damage to the product when dropped. The provision of the bottom cover mounting groove 9 allows for convenient installation of the bottom cover (not shown).

[0018] In this embodiment, the switch and the electrical quantity display hole 6 are located at the top end of the case body 1. However, it should be understood by those skilled in the art that the specific installation positions of the switch and the electrical quantity display hole 6 can be set at other suitable positions on the case body 1 according to actual needs.

[0019] In this embodiment, two screw positioning holes 5 are provided, and the two screw positioning holes 5 are located on both sides of the charging hole 4, respectively. Therefore, by providing two screw positioning holes 5, two corresponding positioning screws can be screwed in simultaneously.

[0020] In a preferred embodiment, the sidewall thickness T1 of the case body 1 is set to 0.8 mm, and the thickness T2 from the top surface of the protrusion 11 to the bottom surface of the case body 1 is 2.65 mm. The above data are preferred embodiments of the sidewall thickness and bottom thickness of the case body 1 so that the case body 1 maintains sufficient strength.

[0021] As shown in Figures 1 to 3, in this embodiment, the maximum distance between opposing side walls of the case body 1 is smaller than the maximum distance between other opposing side walls, thereby allowing the overall shape of the case body 1 to be similar to a flat shape.

[0022] In this embodiment, the bottom cover mounting groove 9 is oval in shape, which prevents the bottom cover from swinging to either side after mounting is complete.

[0023] As shown in FIGS. 4 and 5, a clearance groove 10 surrounding the protrusion 11 is formed around the bottom surface of the mounting cavity 2.

[0024] For ease of manufacturing and to prevent the case body 1 from appearing heavy, aluminum is selected for the case body 1. However, those skilled in the art will understand that other metals can also be used for the case body 1, and so details will not be given here.

[0025] In this embodiment, the dimensions of the bottom cover mounting groove 9 can be enlarged by grinding its surrounding side walls, thereby providing the bottom cover mounting groove 9 with sufficient dimensions to stably mount the bottom cover.

[0026] As shown in Figure 6, during assembly, the corresponding components (such as an atomizer) are simply installed directly into the mounting cavity 2 through the top cover mounting hole 3. The top cover 12 and bottom cover (not shown) are then detachably attached to the top cover mounting hole 3 and bottom cover mounting groove 9, respectively, and the bottom cover can cover the charging hole 4 and screw positioning hole 5. After assembly is complete, the charging hole 4 can be used to insert a charging cable, and the screw positioning hole 5 can be used to screw in a positioning screw, securing the case body 1 and the internal components. The switch and power indicator hole 6 can be used to pass through the switch key 13 and power indicator light 14, making it convenient for people to press the switch key 13 and view the remaining power of the e-cigarette. Furthermore, after the electronic cigarette is installed, only the top cover 12, the switch key 13, and the power indicator lamp 14 may protrude from the case body 1 in terms of the overall appearance. Specifically, the top cover 12, the switch key 13, and the power indicator lamp 14 may protrude from the case body 0 mm-5 mm, respectively, and the bottom surface of the bottom cover is at the same height as the bottom surface of the case body 1.
