Technical Field
[0001] The present application relates to the technical field of electronic cigarette processing equipment, and in particular to an exhaust oil injection needle and an oil injection machine thereof. Background Art
[0002] An electronic cigarette (also known as an "electronic cigarette") or smoking device is an electronic delivery system that generates an aerosol from an atomized substrate for inhalation by the user. The atomized substrate can be a liquid (e.g., a smoke liquid) or a solid or gel (e.g., a smoke paste).

In some other embodiments, it can also be set that the electronic cigarette can move horizontally and vertically, and the position of the exhaust oil filling needle 100 is fixed, and the oil filling work is completed by moving the position of the electronic cigarette.
[0044] See also Figure 2-8 In some embodiments, the exhaust oil filling needle 100 includes a needle body 10, which extends from one end to the other end along the length direction. One end of the needle body 10 is provided with a sharp portion 11, and the other end of the needle body 10 is provided with a mounting portion 12. The needle body 10 is installed on the main body 200 through the mounting portion 12. When in use, the sharp portion 11 pierces the sealed oil tank of the electronic cigarette.
[0045] In some embodiments, the needle body 10 is provided with an oil filling hole 21 at one end near the spike portion 11 for entering the space to be filled during oil filling. The space to be filled herein refers to the internal space of the electronic cigarette oil tank. This space is sealed by a rubber member before and after oil filling. During oil filling, the end of the needle body 10 provided with the oil filling hole 21 passes through the seal to enter the space. The oil filling hole 21 is provided on the needle body 10 near the spike portion 11. In some other embodiments, the oil filling hole 21 can be provided on the spike portion 11. An oil filling channel 22 is formed in the needle body 10. The oil filling hole 21 is connected to the oil filling channel 22. The mounting portion 12 is provided with an oil inlet hole 121 connected to the oil filling channel 22. During use, the oil in the oil filling machine passes through the oil inlet hole 121 and the oil filling channel 22 in sequence, and finally is discharged into the space to be filled in the electronic cigarette oil tank through the oil filling hole 21.
[0046] In some embodiments, in order to remove the air in the space to be filled with oil, the needle body 10 is further provided with an exhaust channel 31 separated from the oil filling channel 22, and the oil filling channel 22 and the exhaust channel 31 extend along the length direction of the needle body 10 respectively, and the needle body 10 is provided with a first air port 32 for entering the space to be filled with oil during oil filling and a second air port 33 for being located outside the space to be filled with oil during oil filling, and the first air port 32 and the second air port 33 are respectively connected to the exhaust channel 31; when filling oil, the air in the electronic cigarette oil tank enters the exhaust channel 31 through the first air port 32 in turn, and is finally discharged to the outside of the oil tank through the second air port 33, so as to prevent the pressure difference inside and outside the oil tank from affecting the oil filling efficiency.
[0047] See also Figure 2 In some embodiments, the number of the first air port 32 and the second air port 33 is multiple, and the number of the oil injection hole 21 is one. In some other embodiments, the number of the first air port 32, the second air port 33 and the oil injection hole 21 is selected as needed, and only the change in the number of the first air port 32, the second air port 33 and the oil injection hole 21 still falls within the scope of protection of this application.

The oil injection channel 22 is arranged in the outer peripheral wall 13, and the exhaust channel 31 is arranged in the outer peripheral wall 13. A partition wall 14 is provided in the outer peripheral wall 13 for separating the exhaust channel 31 and the oil injection channel 22.
[0049] See also Figure 5 、 6 In some embodiments, the partition wall 14 is in sheet form, and the exhaust passage 31 and the oil injection passage 22 are respectively located on both sides of the partition wall 14; see Figure 4 In some other embodiments, the partition wall 14 is hollow tubular, the peripheral wall 13 is sleeved on the outside of the partition wall 14, a space is formed between the peripheral wall 13 and the partition wall 14, the oil injection channel 22 is formed in the hollow interior of the partition wall 14, and the exhaust channel 31 is formed in the space between the partition wall 14 and the peripheral wall 13.
[0050] It is easy to understand that the partition wall 14 can be as follows Figure 4 The hollow tubular structure shown can also be Figure 5 The straight sheet shown is Figure 6 The sheet structure shown has a certain curvature. The shape of the partition wall 14 in this application is not limited to Figure 4 、 5 , 6, it is sufficient to separate the interior of the outer peripheral wall 13 into two non-interconnected channels along its length direction.
[0051] Reference Figure 7 、 8 In some embodiments, the exhaust channel 31 is provided outside the outer peripheral wall 13; specifically, the exhaust channel 31 is a groove 41 opened on the outside of the outer peripheral wall 13, and the groove 41 extends along the length direction of the needle body 10. When oil is injected, a part of the groove 41 extends into the space to be injected with oil, and when oil is injected, another part of the groove 41 is located outside the space to be injected with oil.
[0052] In some other embodiments, the exhaust passage 31 may be provided both inside and outside the outer peripheral wall 13 to increase the exhaust volume.
[0053] In some embodiments, the position of the first air port 32 is higher than the position of the oil filling hole 21 along the length direction of the needle body 10 to prevent the first air port 32 from being blocked by tobacco oil during the oil filling process.
