TECHNICAL FIELD

The utility model relates to the technical field of an electronic cigarette and specifically to a shell of a rechargeable electronic cigarette.

BACKGROUND

An electronic cigarette is a non-combustible cigarette alternative product, which has certain characteristics similar to an ordinary cigarette, can refresh a smoker and satisfy the smoker's pleasure and the use habit developed over years. However, the electronic cigarette is fundamentally different from the ordinary cigarette. The electronic cigarette does not burn, does not contain a tar, and does not contain more than 460 chemical substances that can be produced by combustion of the ordinary cigarette and that can result in respiratory and cardiovascular diseases, thus eliminating a carcinogenic substance in the ordinary cigarette, and producing no “second-hand smoke” that is harmful to others and unfriendly to an environment.

For the electronic cigarette, Authorized Publication No. CN217826764U discloses a rechargeable high-capacity leak-proof disposable electronic cigarette, and specifically discloses that the rechargeable high-capacity leak-proof disposable electronic cigarette includes a shell. The top and the bottom of the shell are connected to an atomizer assembly and a battery assembly, respectively. The atomizer assembly includes a housing. A hanging plate is mounted on the top of the outer side of the housing. A lanyard hole is formed in the inner part of the hanging plate. An oil cup tube is disposed inside the housing. The top and the bottom of the oil cup tube are snap-fitted with a cigarette-holder silica gel and a heating wire silica gel, respectively. Two oppositely symmetrical venting pressure relief grooves are formed inside the cigarette-holder silica gel. The battery assembly includes a bottom cover. A battery is mounted inside the bottom cover. A TYPE-C charging port is disposed on the outer side of the bottom cover. A gas adjusting switch is disposed at the bottom of the bottom cover.

However, the shell of the above rechargeable high-capacity leak-proof disposable electronic cigarette also is connected with the atomizer assembly and the battery assembly, respectively so that a three-section structure including the shell, the housing on the atomizer assembly, and the bottom cover on the battery assembly forms a complete shell body. However, in an actual use process, the shell body formed by the shell, the housing, and the bottom cover may be disconnected from each other in the case that the electronic cigarette falls, that is, the shell body of the electronic cigarette is not strong enough and is not durable enough. A serious damage to the shell body as a result of a fall may also cause the electronic cigarette to no longer be usable. Therefore, there is a need to improve the prior art.

SUMMARY

In view of the above problems existing in the prior art, an objective of the utility model is to provide a shell of a rechargeable electronic cigarette. A shell body is integrally molded and made of metal so that the shell body is not disjointed in the case that the electronic cigarette falls. Therefore, the shell can be more solid and durable, and to a certain extent the service life of the electronic cigarette can be ensured, offering high practicality. In addition, the shell of the rechargeable electronic cigarette also solves other problems in the prior art.

To realize the above objective, the technical solution of the utility model is as follows:

A shell of a rechargeable electronic cigarette includes a shell body integrally molded and made of metal. The shell body is vertically extended. A mounting cavity is disposed inside the shell body. A mounting port of a top cover is disposed at the top of the shell body. The shell body is shaped as a result of a plurality of stamping and stretching. A mounting groove of a bottom cover and a protrusion protruding into the mounting cavity that correspond to each other are formed at the middle of the bottom of the shell body by upward counter stamping, respectively. A charging hole and a screw positioning hole that vertically pass through are also disposed on the bottom surface of the mounting groove of the bottom cover, respectively. Therefore, the protrusion is utilized to increase the tensile strength of the screw positioning hole and enhance the stability after a charging cable is inserted into the charging hole. A switch and a power display hole that horizontally pass through are disposed on the side wall of the shell body. The side wall of the shell body has a thickness of 0.6 mm-1 mm. A distance between the top surface of the protrusion and the bottom surface of the shell body is 2 mm-3 mm, so as to ensure the overall strength of the shell body. The outer walls at a periphery of the shell body are convex arc-shaped surfaces, so that the grip of the shell body feels well. The bottom of the shell body has a cross-sectional area smaller than that of the rest part of the shell body. The cross-sectional area of the lower end of the side wall of the shell body gradually becomes smaller toward the bottom surface, so as to form an arc-shaped transition between the lower end of the side wall of the shell body and the bottom surface of the shell body. Therefore, the arc-shaped transition of the shell body can have a buffering effect when the shell body falls, causing no damage to the shell body. The shell body integrally molded and made of metal can prevent it from being disjointed and damaged when the shell body falls.

There are also following technical solutions:

Further, the side wall of the housing body has a thickness of 0.8 mm. The distance between the top surface of the protrusion and the bottom surface of the shell body is 2.65 mm, so that the strength of the shell body can be ensured.

Further, the maximum distance between two relative side walls of the shell body is less than the maximum distance between other two relative side walls of the shell body, so that the overall shape of the shell body can be formed into a flat-like shape.

Further, the size of the mounting groove of the bottom cover may be enlarged by grinding to the side walls at a periphery of the mounting groove. Therefore, the mounting groove of the bottom cover has a sufficient size to stably mount the bottom cover.

Further, the mounting groove of the bottom cover is oval in shape. This shape allows the bottom cover to be less prone to swinging to two sides after installation is completed.

Further, a ring-shaped clearance groove is disposed around the bottom surface of the mounting cavity.

Further, the shell body is made of aluminum.

The beneficial effects of the utility model are as follows:

(I) For the utility model, the shell body is integrally molded and made of metal so that the shell body is not disjointed when the electronic cigarette falls. Therefore, the shell body is more solid and durable than the existing shell body with three-section design, ensuring the service life of the electronic cigarette to a certain extent.

(II) For the utility model, the side wall of the shell body has a thickness of 0.6 mm-1 mm, and the distance between the top surface of the protrusion and the bottom surface of the shell body is 2 mm-3 mm, so that the overall strength of the shell body is ensured and the shell body is not easy to break. Further, because the protrusion is formed by counter-stamping, the distance between the top surface of the protrusion and the bottom surface of the mounting groove of the bottom cover is basically equal to a distance between the bottom of the protrusion and the bottom surface of the shell body. Therefore, the distance between the top surface of the protrusion and the bottom surface of the mounting groove of the bottom cover can be enough to punch a hole, thus avoiding that the punched hole is easily damaged or difficult for use due to a depth and other reasons. For example, after the corresponding charging hole and the screw positioning hole are punched at the location of the mounting groove of the bottom cover, because the distance between the top surface of the protrusion and the bottom surface of the mounting groove of the bottom cover is enough, the protrusion can be disposed to increase a tensile strength at the screw positioning hole, so that the side wall of the screw positioning hole is not easy to rupture and the charging cable is not easy to swing after being inserted into the charging hole, thereby increasing the stability of the charging cable.

(III) For the utility model, the outer wall has a convex arc-shaped shell body so that the shell body can be more comfortable to hold, that is, the shell body has a good grip.

(IV) For the utility model, the cross-sectional area of the lower end of the side wall of the shell body gradually becomes smaller toward the bottom surface to form an arc transition. Therefore, the position of the arc transition can have a buffering effect in the process of the fall of the shell body compared to the shape of a right angle. The impact resistance of the shell body is improved, so that a product is not easy to be damaged in the process of the fall.

(V) For the utility model, the mounting groove of the bottom cover is disposed, which can easily match and install the bottom cover.

DETAILED DESCRIPTION OF EMBODIMENTS

Specific embodiments in accordance with the present disclosure are specified below in conjunction with various accompanying drawings.

As shown in FIG. 1-FIG. 5, a shell of a rechargeable electronic cigarette includes a shell body 1 integrally molded and made of metal. The shell body 1 is vertically extended. A mounting cavity 2 is disposed inside the shell body 1. A mounting port 3 of a top cover is disposed at the top of the shell body 1. The shell body 1 is shaped as a result of a plurality of stamping and stretching. A mounting groove 9 of a bottom cover and a protrusion 11 protruding into the mounting cavity that correspond to each other are formed at the middle of the bottom of the shell body 1 by upward counter stamping, respectively. A charging hole 4 and a screw positioning hole 5 that vertically pass through are also disposed on the bottom surface of the mounting groove 9 of the bottom cover, respectively. Therefore, the protrusion 11 is utilized to increase the tensile strength of the screw positioning hole 5 and enhance the stability after a charging cable is inserted into the charging hole 4. A switch and a power display hole 6 that horizontally pass through are disposed on the side wall of the shell body 1. The side wall of the shell body 1 has a thickness T1 of 0.6 mm-1 mm. A distance T2 between the top surface of the protrusion 11 and the bottom surface of the shell body is 2 mm-3 mm. The outer walls at a periphery of the shell body 1 are convex arc-shaped surfaces. The bottom of the shell body 1 has a cross-sectional area smaller than that of the rest part of the shell body 1. The cross-sectional area of the lower end of the side wall of the shell body 1 gradually becomes smaller toward the bottom surface, so as to form an arc-shaped transition between the lower end of the side wall of the shell body 1 and the bottom surface of the shell body. The shell body 1 integrally molded and made of metal cannot be disjointed and hence damaged when the shell body falls.

Therefore, with the above-described shell body 1 integrally molded and made of metal, the shell body 1 cannot be disjointed when the electronic cigarette falls. Therefore, the shell body 1 becomes stronger and more durable compared to the existing shell body with a three-section design. The service life of the electronic cigarette is ensured to a certain extent. The thickness T1 of the side wall of the shell body 1 is set as 0.6 mm-1 mm. A distance T2 between the top surface of the protrusion 11 and the bottom surface of the shell body 1 is set as 2 mm-3 mm, so as to ensure the overall strength of the shell body 1, and that the shell body 1 is not easy to rupture. In addition, because the protrusion 11 is formed by counter-stamping, a distance T3 between the top surface of the protrusion 11 and the bottom surface of the mounting groove 9 of the bottom cover is basically equal to a distance T4 between the bottom surface of the protrusion 11 and the bottom surface of the shell body 1. Therefore, the distance T3 between the top surface of the protrusion 11 and the bottom surface of the mounting groove 9 of the bottom cover can be enough to punch a hole, thus avoiding that the punched hole is easily damaged or difficult for use due to a depth and other reasons. For example, after the corresponding charging hole 4 and the screw positioning hole 5 are punched at the location of the mounting groove 9 of the bottom cover, because a distance between the top surface of the protrusion 11 and the bottom surface of the mounting groove 9 of the bottom cover is enough, the protrusion 11 is disposed, which can increase the tensile strength of the screw positioning hole 5. Therefore, the side wall of the screw positioning hole 5 is not easy to break, and the charging cable is not easy to swing after being inserted into the charging hole 4, thereby increasing the stability of the charging cable. The outer wall has a convex arc-shaped shell body 1 so that the shell body 1 can be more comfortable to hold, that is, the shell body has a good grip. The cross-sectional area of the lower end of the side wall of the shell body 1 gradually becomes smaller toward the bottom surface, to form an arc transition. Therefore, the position of the arc transition can have a buffering effect compared to a right-angle shape, which improves the impact resistance of the shell body 1, so that a product is not easy to be damaged in the process of falling. The mounting groove 9 of the bottom cover is disposed, which can easily match and install the bottom cover (not shown in the figure).

In this embodiment, the switch and the power display hole 6 are located at the upper end of the shell body 1. However, a person skilled in the art should know that for the specific setting position of the switch and the power display hole 6, according to actual need, the switch and the power display hole is able to be disposed in other suitable positions of the shell body 1.

In this embodiment, only two screw positioning holes 5 are located on the two sides of the charging hole 4, so that two positioning screws can be correspondingly screwed at the same time after the two screw positioning holes 5 are disposed.

Preferably, the thickness T1 of the side wall of the shell body 1 is set to 0.8 mm. The distance T2 between the top surface of the protrusion 11 and the bottom surface of the shell body 1 is 2.65 mm. The above data is a preferred way of the thickness of the side wall and the thickness of the bottom of the shell body 1 so as to allow the shell body 1 to remain sufficiently strong.

As shown in FIG. 1-FIG. 3, in this embodiment, the maximum distance between two relative side walls of the shell body 1 is less than the maximum distance between other two relative side walls of the shell body, so that the overall shape of the shell body 1 can be formed into a flat-like shape.

In this embodiment, the mounting groove 9 of the bottom cover is oval in shape. This shape allows the bottom cover to be less prone to swinging to two sides after installation is completed.

As shown in FIGS. 4 and 5, one clearance groove 10 that surrounds the protrusion 11 is formed at a periphery of the bottom surface of the mounting cavity 2.

To be conducive to production and fabrication, and in order that the shell body 1 is not too heavy, the shell body 1 is chosen to be made of aluminum. However, a person skilled in the art knows that for the material selection of the shell body 1, the shell body is able to be made of other metals, which will not be specifically discussed herein.

In this embodiment, the size of the mounting groove of the bottom cover may enlarged by grinding to the side walls at a periphery of the mounting groove. Therefore, the mounting groove of the bottom cover has a sufficient size to stably mount the bottom cover.

As shown in FIG. 6, during assembly, the corresponding parts (e.g., an atomizer) are assembled directly into the mounting cavity 2 at the mounting port 3 of the top cover. The top cover 12 and the bottom cover (not shown in the figure) can be detachably mounted at the mounting port 3 of the top cover and mounting groove 9 of the bottom cover, respectively. The bottom cover can cover the charging hole 4 and the screw positioning hole 5. After the assembly is completed, the charging cable can be inserted into the position of the charging hole 4. The positioning screw can be screwed into the position of the screw positioning hole 5 so that the shell body 1 is fixed to the internal parts. A switch button 13 and the power display light 14 can be pierced out at the positions of the switch and the power display hole 6, so that the switch button 13 is conveniently pressed and the remaining power level of the electronic cigarette is shown. In addition, after the electronic cigarette is mounted, in an overall appearance, only the top cover 12, the switch button 13, and the power display light 14 may protrude from the shell body 1. Specifically, the top cover 12, the switch button 13, and the power display light 14 protrude from the shell body by 0 mm-5 mm, respectively. The bottom surface of the bottom cover is flush with the bottom surface of the shell body 1.

The disclosure scope of the utility model is not defined by the above embodiments, but is limited by the appended claims and their equivalent scope. A charging hole and a screw positioning hole are also disposed on the bottom surface of the mounting groove of the bottom cover, respectively. A switch and a power display hole are also disposed on the side wall of the shell body. The side wall of the shell body has a thickness of 0.6 mm-1 mm, a distance between a top surface of the protrusion and a bottom surface of the shell body is 2 mm-3 mm. The cross-sectional area of the lower end of the side wall of the shell body gradually becomes smaller toward the bottom surface. The shell body integrally molded and made of metal allows the shell body not to become disjointed when the electronic cigarette falls, making the shell body stronger and more durable.
