[0001] This utility model relates to the field of electronic cigarette structure, specifically to a heating wire routing structure for a dual-oil-cup electronic cigarette. Background Technology

[0002] In existing dual-oil-cup electronic cigarettes, the upper heating wire leads pass through a fiberglass tube in the lower oil-collecting cotton, then through a lower silicone film, and are soldered to the board. This method has the following drawbacks:

[0003] First, the large amount of assembly materials increases production costs and is not conducive to improving production efficiency.

[0004] Second, during the production and assembly process, when welding the heating wire leads, the leads may be pulled, causing the fiberglass tubes on the leads to squeeze the oil cup's oil reservoir cotton, resulting in oil accumulation in the oil cup's oil reservoir cotton. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a wiring structure for the heating wire of a dual-oil-cup electronic cigarette.

[0006] This utility model relates to a dual-oil-cup electronic cigarette heating wire routing structure. The dual-oil-cup electronic cigarette includes a lower oil cup and an upper oil cup positioned above the lower oil cup, as well as a connecting silicone sealant positioned between the lower and upper oil cups to isolate them. It also includes a lower silicone sealant structure positioned below the lower oil cup. The dual-oil-cup electronic cigarette heating wire routing structure includes a guide hole located in the middle of the connecting silicone sealant for the upper oil cup heating wire lead to pass through. The side wall of the lower oil cup is provided with a first lead channel, and the lower silicone sealant structure is provided with a second lead channel at a corresponding position to the lead channel. One end of the heating wire lead of the upper oil cup can pass through the guide hole, the first lead channel, and the second lead channel to be electrically connected to the circuit board.

[0007] Furthermore, the dual-oil-cup electronic cigarette also includes a bracket disposed below the lower oil cup for fixing the battery and circuit board, and the heating wire wiring structure of the dual-oil-cup electronic cigarette also includes a wire-passing hole disposed on the bracket for the heating wire lead wire to pass through.

[0008] Furthermore, the guide hole is an inclined guide hole, the upper end of the guide hole is corresponding to the heating wire in the middle of the upper oil cup, and the lower part of the guide hole extends to the vicinity of the side wall of the lower oil cup, corresponding to the first lead wire channel on the outer wall of the lower oil cup.

[0009] As an improvement of this utility model, the first lead wire channel is a through hole that vertically penetrates the side wall of the lower oil cup.

[0010] As another improvement of this utility model, the first lead channel includes a first channel disposed on the upper end face of the lower oil cup corresponding to the guide hole of the connecting silicone and a second channel disposed on the side wall of the lower oil cup, and a connecting hole communicating with the second channel is provided below the first channel.

[0011] Furthermore, the connecting silicone is sealed to the upper end face of the lower oil cup, and after the heating wire leads pass through the guide hole and the connecting hole, the connecting silicone around the guide hole seals the channel between the first channel and the guide hole.

[0012] Furthermore, the second channel is a first wiring groove arranged longitudinally on the side wall surface of the electronic cigarette.

[0013] Furthermore, the second lead channel is a second wiring channel that is configured corresponding to the first wiring channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model sets a guide hole on the connecting silicone and designs a first lead wire channel on the side wall of the lower oil cup to pass the heating wire lead wire of the upper oil cup out of the oil cup, changing the traditional method of passing the wire through the inside of the lower oil cup, thereby solving the problem of oil accumulation in the lower oil storage cotton caused by the upper heating wire lead wire squeezing the lower oil storage cotton.

[0020] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the present invention relates to a dual-oil-cup electronic cigarette heating wire routing structure applied to a dual-oil-cup electronic cigarette. The dual-oil-cup electronic cigarette includes a lower oil cup 2 stacked on top of the lower oil cup 2 and an upper oil cup 1 disposed above the lower oil cup 2, and a connecting silicone 4 disposed between the lower oil cup 2 and the upper oil cup 1 to isolate the lower oil cup 2 and the upper oil cup 1. It also includes a lower silicone structure 5 disposed below the lower oil cup 2. The dual-oil-cup electronic cigarette heating wire routing structure includes a guide hole 41 disposed in the middle of the connecting silicone 4 for the heating wire lead wire 111 of the upper oil cup 1 to pass through. The side wall of the lower oil cup 2 is provided with a first lead wire channel 21, and the lower silicone structure 5 is provided with a second lead wire channel 51 at the corresponding position of the lead wire channel. One end of the heating wire lead wire 111 of the upper oil cup 1 can pass through the guide hole 41, the first lead wire channel 21, and the second lead wire channel 51 and be electrically connected to the circuit board 6.

[0023] Preferably, in this example, the circuit board 6 is disposed below the lower oil cup 2. The dual oil cup electronic cigarette also includes a bracket 3 disposed below the lower oil cup 2 for fixing the battery and the circuit board 6. The heating wire routing structure of the dual oil cup electronic cigarette also includes a wire hole disposed on the bracket 3 for the heating wire lead wire to pass through.

[0024] In this example, the wire-passing hole includes a third lead channel 301 corresponding to the second lead channel 51. The circuit board 6 is located on the other side of the bracket 3 opposite to the third lead channel 301. Therefore, a through hole 302 is also provided on the bracket 3 for leading the heating wire lead 111 of the upper oil cup to one side of the circuit board 6 for soldering. Alternatively, the circuit board 6 can be located on one side of the third lead channel 301, allowing direct soldering of the heating wire lead 111 through the third lead channel 301 to the circuit board 6.

[0025] This invention provides a guide hole on the connecting silicone 4 and designs a first lead wire channel 21 on the side wall of the lower oil cup 2 to pass the heating wire 111 of the upper oil cup out of the oil cup. Another lead wire channel is set outside the oil storage cavity of the lower oil cup, thereby changing the traditional method of passing the wire through the inside of the lower oil cup and solving the problem of oil accumulation in the lower oil storage cotton caused by the upper heating wire squeezing the lower oil storage cotton.

[0026] Preferably, in this example, the guide hole 41 is an inclined guide hole. The upper end of the guide hole is correspondingly arranged with the heating wire 11 in the middle of the upper oil cup 1. The lower part of the guide hole 41 extends to the vicinity of the side wall of the lower oil cup 2 and is correspondingly arranged with the first lead wire channel 21 on the outer wall of the lower oil cup.

[0027] As an embodiment of the present invention, the first lead wire channel 21 can be configured as a through hole that vertically penetrates the side wall of the lower oil cup 2.

[0028] As a preferred embodiment of the present invention, the first lead channel 21 includes a first channel 213 disposed on the upper end face of the lower oil cup corresponding to the guide hole of the connecting silicone and a second channel 212 disposed on the side wall of the lower oil cup. A connecting hole 211 communicating with the second channel 213 is provided below the first channel 213.

[0029] In this example, the first channel 213 opens onto the upper surface of the lower oil cup 2 where it connects to the connecting silicone 4. Since the connecting silicone 4 is sealed to the upper surface of the lower oil cup 2, after the heating wire lead 111 passes through the guide hole 41 and the connecting hole 211, the connecting silicone around the guide hole 41 can seal the upper part of the first channel 213, thereby sealing the channel between the first channel 21 and the guide hole 41, improving the overall sealing performance of the channel, and making the structure of this dual-oil cup electronic cigarette more reliable.

[0030] To improve the ease of wiring, in this example, the second channel 212 is a first wiring groove arranged vertically on the side wall surface of the electronic cigarette, and the second lead 51 is a second wiring groove arranged corresponding to the first wiring groove. The open design makes it easier to lead out the heating wire 111 of the oil cup.

[0031] In this example, the circuit board 6 is fixed to the mounting surface 303 of the bracket 3 by screws 601. The heating wire lead of the lower oil cup is still led out to the circuit board 6 below through the connecting structure 52 in the middle of the lower silicone structure 5 and the connecting hole 304 on the bracket. In addition, this example retains the vent hole 22 structure on the upper end of the lower oil cup 2 to realize the suction function.

[0032] This invention, through its structural design, leads the heating wire lead wire routing channel of the upper oil cup to the outside of the lower oil cup, separating it from the heating wire lead wire of the lower oil cup. This effectively avoids the oil accumulation problem caused by the heating wire lead wire of the upper oil cup passing through the inside of the lower oil cup. Furthermore, the external routing simplifies the assembly and welding of this invention, improving assembly efficiency. This invention also eliminates the need for a separate insulating oil storage cotton and fiberglass tube for the lead wire, thus reducing the material usage of the fiberglass tube and lowering production costs.

[0033] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
