Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a power supply device of an electronic cigarette and the electronic cigarette. Background Art

[0002] Existing electronic cigarettes usually provide interfaces for users to charge or upgrade the system. The interface needs to be configured with a circuit board to realize the functions of charging or data updating. However, the existing interface circuit board is usually fixed by screws, and it is locked to the shell by screwing screws on the edge of the interface circuit board. This has two problems. One is that at least three screws are required for fixing, which increases the installation process, and the circuit board is easy to warp during the installation process; on the other hand, the middle part of the circuit board lacks support, and when it is subsequently subjected to the vertical force of the interface terminal, it is easy to break the circuit board and cause damage.

[0003] Therefore the prior art needs to be improved and enhanced. Summary of the invention

[0030] Please refer to Figure 1 , which is a schematic structural diagram of a preferred embodiment of a power supply device for an electronic cigarette proposed by the present invention. The power supply device includes a housing 1, a plug-in terminal 2, a circuit board 3, and a limiting member 4. One end of the plug-in terminal 2 passes through the housing 1, and the other end is vertically connected to the circuit board 3. Installation grooves 11 are provided on both opposite side walls of the housing 1. Both ends of the circuit board 3 and both ends of the limiting member 4 are received in the two installation grooves 11. The two sides of the part of the limiting member 4 received in the installation groove 11 are respectively in contact with the circuit board 3 and the inner wall of the installation groove 11 to fasten the circuit board 3 to the housing 1. In this embodiment, by inserting both ends of the circuit board 3 into the installation groove 11 and then inserting the limiting member 4 between the circuit board 3 and the installation groove 11, the circuit board 3 is fastened in the installation groove 11. In this way, it is not necessary to use the method of screwing in multiple screws to lock the circuit board 3, but only need to snap both ends of the limiting member 4 into the two installation grooves 11, which reduces the installation process, facilitates installation, and improves the installation efficiency.

[0031] In this embodiment, as Figure 3As shown, at one end of the housing 1, a first protrusion 12 and a second protrusion 13 are provided at intervals, and at the other end, the first protrusion 12 and the second protrusion 13 are also provided correspondingly at intervals. Among them, the second protrusion 13 is closer to the insertion terminal 2 than the first protrusion 12. The first protrusion 12, the second protrusion 13 and the inner wall of the housing 1 at the same end of the housing 1 enclose an installation groove 11. The installation groove 11 is a U-shaped groove, the inner wall of the housing 1 serves as the bottom wall of the U-shaped groove, the side of the first protrusion 12 close to the second protrusion 13 serves as the first side wall, and the side of the second protrusion 13 close to the first protrusion 12 serves as the second side wall. The two ends of the circuit board 3 and the limiting member 4 are respectively located in two installation grooves 11, and one side of the circuit board 3 is in contact with and abuts against the limiting member 4, and the other side abuts against one of the first side wall and the second side wall to fix the circuit board 3. That is, the circuit board 3 and the limiting member 4 are clamped between the first protrusion 12 (the first side wall) and the second protrusion 13 (the second side wall), so as to restrict the displacement of the circuit board 3 in the direction perpendicular to the circuit board 3.

[0032] Preferably, as Figure 5 shown, at least one rib 44 is provided on the side of the limiting member 4 facing the circuit board 3. In this way, the rib 44 on the limiting member 4 is in contact with the circuit board 3, so that the limiting member 4 and the circuit board 3 form a small surface contact, and thus there is a gap between the part of the limiting member 4 without the rib 44 and the circuit board 3, which is convenient for the installation of the limiting member 4. In practical applications, the rib 44 can be provided at the end, middle or other positions on the side of the limiting member 4 facing the circuit board 3. The shape of the rib 44 can be strip-shaped, circular, square or other irregular shapes, which are not limited here.

[0033] In practical applications, the limiting member 4 can be located between the circuit board 3 and the first protrusion 12, and the circuit board 3 is located between the limiting member 4 and the second protrusion 13. Since the limiting member 4 abuts against the circuit board 3 and the first protrusion 12 respectively, both sides of the end of the circuit board 3 abut against the limiting member 4 and the second protrusion 13 respectively, so as to fasten the end of the circuit board 3 in the installation groove 11 and prevent the circuit board 3 from moving in the direction perpendicular to the plane where the circuit board 3 is located under the action of the insertion terminal 2. Similarly, the limiting member 4 can also be located between the circuit board 3 and the second protrusion 13, and the circuit board 3 is located between the limiting member 4 and the first protrusion 12. Since the limiting member 4 abuts against the circuit board 3 and the second protrusion 13 respectively, both sides of the end of the circuit board 3 abut against the limiting member 4 and the first protrusion 12 respectively.

[0034] Preferably, as Figure 1 and Figure 2As shown, the limiting member 4 is located between the circuit board 3 and the first protrusion 12, so that the circuit board 3 is located between the limiting member 4 and the second protrusion 13. At the same time, since the second protrusion 13 is closer to the plug-in terminal 2 than the first protrusion 12, that is, the limiting member 4 is located on the side of the circuit board 3 away from the plug-in terminal 2. The circuit board 3 is clamped between the plug-in terminal 2 and the limiting member 4. Since the plug-in terminal 2 is vertically connected to the circuit board 3, when an external load or power supply is plugged into the plug-in terminal 2, the plug-in terminal 2 exerts a force perpendicular to the circuit board 3 on the circuit board 3. At this time, the limiting member 4 is located on the side of the circuit board 3 away from the plug-in terminal 2 and supports the circuit board 3 to prevent the circuit board 3 from being bent and causing damage to the printed circuit.

[0035] In this embodiment, as Figure 5 shown, the limiting member 4 includes a body 41 and two limiting portions 42, and the two limiting portions 42 are formed by extending outward from both ends of the body 41 respectively. One of the two limiting portions 42 is snapped into one mounting groove 11, and the other is snapped into the other mounting groove 11, and the two limiting portions 42 are respectively in contact with the circuit board 3. Further, the two limiting portions 42 respectively form limiting steps 43 with the body 41. The two limiting steps 43 are respectively adapted to the first protrusions 12 at both ends of the housing 1 to realize the positioning and limiting of the limiting member 4. Specifically, the limiting step 43 includes a first bearing surface 431, a height surface 432 and a second bearing surface 433, and the first bearing surface 431 and the second bearing surface 433 are parallel and both perpendicular to the height surface 432. The first bearing surface 431 is located below the second bearing surface 433. The first bearing surface 431 is in contact with the first side wall, and the height surface 432 is in contact with one side surface of the first protrusion 12. The L-shaped surface formed by the first side wall and the other side surface of the first protrusion is mutually attached to the L-shaped surface formed by the first bearing surface 431 and the height surface 432 to position and limit the limiting member 4.

[0036] Further, as Figure 3 and Figure 4As shown, since the circuit board 3 is located between the limiting member 4 and the second protrusion 13, in order to facilitate the installation of the circuit board 3, a positioning post 131 is provided on the side of the second protrusion 13 facing the first protrusion 12. Correspondingly, the circuit board 3 is provided with a positioning groove 31 adapted to the positioning post 131. When the two ends of the circuit board 3 are respectively received in the corresponding installation grooves 11, the positioning post 131 is received in the corresponding positioning groove 31. In this way, the positioning post 131 can not only position the circuit board 3, but also prevent the circuit board 3 from displacing along the plane where it is located. Preferably, the height of the positioning post 131 is less than or equal to the thickness of the circuit board 3. This makes the side of the circuit board 3 facing away from the second protrusion 13 a flat surface, preventing the phenomenon that the limiting member 4 can only contact the positioning post 131 and cannot contact the circuit board 3. It should be noted that the positioning groove can also be provided on the second protrusion, and correspondingly, the positioning post is provided on the circuit board.

[0037] In an embodiment of the present invention, as Figure 3 shown, the housing 1 includes a middle frame 15, a front shell 16 and a rear shell (not shown in the figure). The front shell 16 is connected to the rear shell, and the two are respectively located on both sides of the middle frame 15 and enclose a receiving groove with the middle frame 15. The installation grooves 11 are respectively provided at both ends of the receiving groove. In practical applications, the installation grooves 11 can be provided on the opposite side walls of the receiving groove, or they can be provided on the adjacent side walls of the receiving groove. Preferably, the installation grooves 11 are provided on the opposite side walls of the receiving groove. That is, the first protrusions 12 and the second protrusions 13 are provided on both opposite side walls of the receiving groove.

[0038] Further, as Figure 2 and Figure 3 shown, the circuit board 3, the two second protrusions 13 located at both ends of the receiving groove, and the inner wall of the receiving groove enclose a receiving cavity 17. A through hole 14 is provided on the inner wall of the receiving cavity 17 opposite to the circuit board 3. One end of the plug-in terminal 2 is received in the receiving cavity 17 and is vertically connected to the circuit board 3. The other end passes through the through hole 14 and is exposed outside the housing 1 for external power supply or load plugging.

[0039] In an embodiment of the present invention, the shape of the circuit board 3 is adapted to the receiving groove. When the two ends of the circuit board 3 are received in the installation grooves 11, the respective sides of the circuit board 3 are respectively attached to the inner wall of the receiving groove to further limit the displacement of the circuit board 3 along the plane where it is located through the inner wall of the receiving groove, thereby preventing the circuit board 3 from shaking left and right.

[0040] The present invention also provides an electronic cigarette, which includes the power supply device of the electronic cigarette described in any one of the above. The specific structure of the power supply device of this electronic cigarette refers to the above embodiments. Since the electronic cigarette adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
