Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and specifically to a rechargeable electronic cigarette case.

Background Art

[0002] An electronic cigarette is a non-combustible alternative product to traditional cigarettes. It has some features similar to ordinary cigarettes and can refresh smokers' moods and satisfy their pleasure and long-term usage habits. However, it is essentially different from ordinary cigarettes. Electronic cigarettes do not burn, do not contain tar, and do not contain more than 460 kinds of chemicals that cause respiratory and cardiovascular diseases when ordinary cigarettes burn. Therefore, except for the carcinogens in ordinary cigarettes, there is no harm of "environmental tobacco smoke" to others and no environmental pollution.

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

[0004] However, in the above-mentioned rechargeable large-capacity leak-proof disposable electronic cigarette, an atomizer module and a battery module are respectively connected to the case, and thereby a three-stage structure such as the case, the case on the atomizer module, and the bottom cover on the battery module forms a complete case body. However, during actual use, the case body composed of the above-mentioned case, housing, and bottom cover may fall off from each other when the electronic cigarette drops, that is, the case body of the electronic cigarette is not strong enough and lacks durability. When the damage to the case body caused by dropping is serious, the electronic cigarette may become unusable. Therefore, improvements to the prior art are needed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the problems existing in the above prior art, the object of the present invention is to provide a rechargeable electronic cigarette case that is stronger, more durable, and has a certain degree of guarantee for the service life of the electronic cigarette and high practicality by installing an integrally formed metal case body, so that the case body will not fall off when the electronic cigarette drops; also, other problems in the prior art are solved.

Means for Solving the Problems

[0006] To achieve the above object, the technical solution of the present invention is as follows: A rechargeable electronic cigarette case, comprising an integrally formed metal case body; the case body has a shape extending in the vertical direction; an installation cavity is provided inside the case body, and a top cover installation opening is provided at the upper part; the shape of the case body is formed by multiple press stretching operations, and at the middle position of the bottom of the case body, a bottom cover installation groove corresponding thereto and a protrusion protruding into the installation cavity are respectively formed by upward reverse pressing. A charging hole and a screw positioning hole penetrating in the vertical direction are respectively provided on the bottom surface of the bottom cover installation groove. The protrusion increases the tensile strength in the screw positioning hole and the stability after the charging cable is inserted into the charging hole; on the side wall of the case body, a horizontally penetrating switch and an electricity quantity display hole are further provided; the side wall thickness of the case body is 0.6 mm - 1 mm, and the thickness from the upper surface of the protrusion to the bottom surface of the case body is 2 mm - 3 mm, thereby ensuring the overall strength of the case body; the outer peripheral wall of the case body is all in the shape of an arc surface of an external protrusion, improving the grip feel of the case body; the cross-sectional area of the bottom of the case body is smaller than the cross-sectional area of the remaining part of the case body, and an arc transition is formed between the lower end of the side wall of the case body and the bottom surface of the case body so that an arc transition is formed between the lower end of the side wall of the case body and the bottom surface of the case body. When the case body falls, this arc transition exerts a buffering effect, making the case body less likely to be damaged; the integrally formed metal case body can be prevented from falling off or being damaged when dropped.

[0007] Also, the following technical solutions are also included: Furthermore, the side wall thickness of the case body is 0.8 mm; the thickness between the upper 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, among the case body, the maximum distance between two opposite side walls is smaller than the maximum distance between other two opposite side walls, and the overall shape of the case body can be made into a shape similar to a flat shape.

[0009] Furthermore, the dimensions of the bottom cover mounting groove can be enlarged by grinding its peripheral side wall, so that the bottom cover mounting groove has sufficient dimensions to stably mount the bottom cover.

[0010] Furthermore, the bottom cover mounting groove is elliptical, and this shape prevents the bottom cover from swaying to both sides after the mounting is completed.

[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.

Advantages of the Invention

[0013] The beneficial effects of the present invention are as follows: (1) By installing an integrally formed metal case body, the case body will not fall off when the e-cigarette drops. Thus, the case body is stronger and more durable than the case body with the conventional three-piece design, and can guarantee the service life of the e-cigarette to a certain extent. (2) The present invention sets the side wall thickness of the case body to 0.6 mm - 1 mm and the thickness from the upper surface of the protrusion to the bottom surface of the case body to 2 mm - 3 mm, thereby ensuring the overall strength of the case body and making it difficult to rupture. Also, since the protrusion is formed by reverse pressing, the thickness from the upper surface of this protrusion to the bottom surface of the bottom cover mounting groove is approximately the same as the thickness from the bottom of the protrusion to the bottom surface of the case body. The thickness from the upper surface of the protrusion to the bottom surface of the bottom cover mounting groove can be maintained at a sufficient thickness to drill holes, preventing the drilled holes from being easily damaged due to depth or being difficult to use during operation. For example, after drilling the charging hole and the screw positioning hole corresponding to the position of the bottom cover mounting groove, since the thickness from the upper surface of the protrusion to the bottom surface of the bottom cover mounting groove is sufficient, the installation of the protrusion can increase the tensile strength in the screw positioning hole, making it difficult to rupture the side wall of the screw positioning hole. Also, after inserting the charging cable into the charging hole, it is difficult to swing, enhancing the stability of the charging cable. (3) The case body of the present invention, whose peripheral outer wall forms an arc-shaped surface of an external protrusion, improves the grip feel of the case body, that is, the case body can be gripped more comfortably. (4) The installation in which the cross-sectional area of the lower end of the side wall of the case body of the present invention gradually decreases in the bottom direction can form an arc transition. Thereby, the position of the arc transition can exert a buffering effect during the fall of the case body compared to a right-angled shape, and enhance the impact resistance of the case body, making the product difficult to be damaged during the fall. (5) The present invention can be conveniently used in accordance with the installation of the bottom cover by providing a bottom cover mounting groove.

Embodiments for Carrying out the Invention

[0015] Hereinafter, with reference to each drawing, specific embodiments according to the present disclosure will be specifically described.

[0016] As shown in FIGS. 1 to 5, a rechargeable electronic cigarette case includes an integrally formed metal case body 1; the case body 1 has a shape extending in the longitudinal direction; an attachment cavity 2 is provided inside the case body 1, and a top cover attachment port 3 is provided at the upper part; the shape of the case body 1 is formed by multiple press stretches, and at the middle position of the bottom of the case body 1, a bottom cover attachment groove 9 and a protrusion 11 protruding into the attachment cavity are respectively formed by upward reverse pressing. A charging hole 4 and a screw positioning hole 5 penetrating vertically are respectively provided on the bottom surface of the bottom cover attachment groove 9. The protrusion 11 increases the tensile strength at the screw positioning hole 5 and the stability after the charging cable is inserted into the charging hole 4; on the side wall of the case body 1, a horizontally penetrating switch and an electric quantity display hole 6 are further provided; the side wall thickness T1 of the case body 1 is 0.6 mm - 1 mm, and the thickness T2 from the upper surface of the protrusion 11 to the bottom surface of the case body is 2 mm - 3 mm; the peripheral outer wall of the case body 1 is all in the shape of an arc surface of an external protrusion; the cross-sectional area of the bottom of the case body 1 is smaller than the cross-sectional area of the remaining part 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 in the bottom surface direction so as to form an arc transition between the lower end of the side wall of the case body 1 and the bottom surface of the case body; the integrally formed metal case body 1 can be made so as not to drop off or be damaged during falling.

Example

[0017] Therefore, with the integrally formed metal case body 1 described above, when the electronic cigarette drops, the case body 1 will not fall off. The case body 1 is stronger and more durable than the conventional three-piece designed case body, and can guarantee the service life of the electronic cigarette to a certain extent. By setting the side wall thickness T1 of the case body 1 to 0.6 mm - 1 mm and the thickness T2 from the upper surface of the protrusion 11 to the bottom surface of the case body 1 to 2 mm - 3 mm, the overall strength of the case body 1 can be guaranteed and it can be made less likely to rupture. Also, since the protrusion 11 is formed by reverse pressing, the thickness T3 from the upper surface of this protrusion 11 to the bottom surface of the bottom cover mounting groove 9 and the thickness T4 from the bottom of the protrusion 11 to the bottom surface of the case body 1 are approximately the same. Thus, the thickness T3 from the upper surface of the protrusion 11 to the bottom surface of the bottom cover mounting groove 9 can maintain a sufficient thickness to drill holes, preventing the drilled holes from being easily damaged due to depth or being difficult to use during operation. For example, after opening the charging hole 4 and the screw positioning hole 5 corresponding to the position of the bottom cover mounting groove 9, since the thickness between the upper surface of the protrusion 11 and the bottom surface of the bottom cover mounting groove 9 is sufficient, the installation of the protrusion 11 can increase the tensile strength of the screw positioning hole 5, making it less likely to rupture the side wall of the screw positioning hole 5, making it less likely to swing after the charging cable is inserted into the charging hole 4, and enhancing the stability of the charging cable. The case body 1 with the outer peripheral wall in the shape of an arc surface of an external protrusion improves the gripping feel of the case body 1, that is, the gripping feel of the case body 1 is good. The installation where the cross-sectional area of the lower end of the side wall of the case body 1 gradually decreases in the bottom surface direction can form an arc transition. The position of the arc transition can exert a buffering effect during the process of the case body 1 falling compared to a right-angled shape, and can also enhance the impact resistance of the case body 1, making the product less likely to be damaged during a fall. By providing the bottom cover mounting groove 9, it can be conveniently used according to the installation of the bottom cover (not shown).

[0018] In this embodiment, the switch and the electricity quantity display hole 6 are located at the upper end of the case body 1. However, those skilled in the art should understand that the specific installation positions of the switch and the electricity quantity display hole 6 can also be installed at other appropriate positions of the case body 1 according to actual requirements.

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

[0020] As a preferred embodiment, the side wall thickness T1 of the case body 1 is set to 0.8 mm, and the thickness T2 from the upper surface of the protrusion 11 to the bottom surface of the case body 1 is 2.65 mm. The above data are the preferred embodiments of the side wall thickness and the bottom thickness of the case body 1 so that the case body 1 can maintain sufficient strength.

[0021] As shown in FIGS. 1 to 3, in this embodiment, among the case body 1, the maximum distance between the two opposite side walls is smaller than the maximum distance between the other two opposite side walls, so that the overall shape of the case body 1 can be made similar to a flat shape.

[0022] In this embodiment, the bottom cover mounting groove 9 is elliptical, and this shape prevents the bottom cover from swinging to both sides after being mounted.

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

[0024] In order to facilitate manufacturing and make the case body 1 not look heavy, the case body 1 is selected to be made of aluminum. However, those skilled in the art understand that other metals can also be adopted for the material selection of the case body 1, and the details are omitted here.

[0025] In this embodiment, the dimensions of the bottom cover mounting groove 9 can be enlarged by grinding its peripheral side wall, so that the bottom cover can be stably mounted with sufficient dimensions in the bottom cover mounting groove 9.

[0026] As shown in FIG. 6, when assembling, the corresponding parts (such as the atomizer) can be directly assembled into the mounting cavity 2 through the top cover mounting port 3. The top cover 12 and the bottom cover (not shown) are detachably mounted in the top cover mounting port 3 and the bottom cover mounting groove 9 respectively, and the bottom cover can cover the charging hole 4 and the screw positioning hole 5. After the assembly is completed, it can be used to insert the charging cable at the position of the charging hole 4 and to screw in the positioning screw at the position of the screw positioning hole 5 to fix the case body 1 and the internal parts; the positions of the switch and the power amount display hole 6 can be used to pass the switch key 13 and the power amount display lamp 14, which is convenient for people to press the switch key 13 and display the remaining power amount of the electronic cigarette. In addition, after the installation of the electronic cigarette is completed, only the top cover 12, the switch key 13 and the power amount display 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 amount display lamp 14 protrude from the case body by 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.

[0027] The scope of the disclosure of the present invention is not limited by the above-described embodiments, but is limited by the appended patent claims and their equivalent scope.
