[0023] The cleaning mechanism includes a housing 5 fixed to the upper side of the oil injection shell 1. A servo motor 6 is fixedly connected to the rear side wall of the housing 5. The main shaft end of the servo motor 6 penetrates into the housing 5 and is fixedly connected with a cam 7. One end of the cam 7 is hinged to a swing rod 8. The lower end of the swing rod 8 is hinged to a lifting plate 9. The lower bottom wall of the lifting plate 9 is fixedly connected with sliding rods 10 arranged at equal intervals. The lower ends of the sliding rods 10 penetrate into the oil guiding cavity 2 and are fixedly connected with a scraper 11. The lower bottom wall of the scraper 11 is fixedly connected with a cleaning thimble 12 that matches the inner diameter of the oil injection needle tube 4. When it is necessary to regularly clean the oil injection needle tube 4, start the servo motor 6 to work and drive the cam 7 to rotate. At this time, the swing rod 8 can be driven to generate a swinging displacement, and then the lifting plate 9 can be pulled to reciprocate up and down in the housing 5, and then drive the scraper 11 fixed to the sliding rod 10 to reciprocate, driving the cleaning thimble 12 to reciprocally insert into the oil injection needle tube 4, pressing the blocked e-liquid in the oil injection needle tube 4 downward to achieve the cleaning effect of the oil injection needle tube 4. At the same time, open the oil drain valve port 20 to squeeze and discharge the remaining e-liquid in the oil guiding cavity 2. The cleaning is convenient and the cleaning effect is good.

[0024] As Figure 2 shown: The pressing mechanism includes two fixed hole plates 13 symmetrically fixed at both ends of the bottom of the oil injection shell 1. A moving rod 14 is inserted and slidably connected in each of the two fixed hole plates 13. The lower ends of the two moving rods 14 are fixedly connected with a pressing plate 15. A pressing spring 16 is fixedly connected between the fixed hole plate 13 and the pressing plate 15. The pressing spring 16 is sleeved on the outer side of the moving rod 14. A through hole 17 corresponding to the oil injection needle tube 4 is penetrated between the upper and lower walls of the pressing plate 15. When the oil injection needle tube 4 moves downward and inserts into the e-cigarette oil storage shell, the pressing plate 15 first abuts against the side wall of the open end of the oil storage shell. At this time, the pressing spring 16 is compressed and contracts to generate an elastic force. Using its elastic force, the pressing plate 15 can be pressed against the oil storage shell for positioning and fixing, so that the oil injection needle tube 4 can be accurately inserted into the oil storage shell to prevent the oil storage shell from shifting.

[0027] As Figure 3 shown: The inner walls on both sides of the housing 5 are in sliding connection with the side walls at both ends of the lifting plate 9, so that the lifting plate 9 keeps moving straight up and down.

[0028] As Figure 3As shown in the figure: a sliding hole communicating with the housing 5 is provided on the upper side wall of the oil guiding cavity 2, and the inner wall of the sliding hole is slidably connected with the sliding rod 10 to facilitate the lifting displacement of the sliding rod 10.

[0029] As Figure 1 shown in the figure: a flushing valve head 19 communicating with the oil guiding cavity 2 is provided on the upper part of the front side wall of the oil injection shell 1, and an oil discharge valve port 20 communicating with the oil guiding cavity 2 is provided on the lower part of the front side wall of the oil injection shell 1. An external flushing device can be connected to flush and clean the oil guiding cavity 2 to improve the cleaning effect.

[0030] Working principle: When it is necessary to regularly clean the oil injection needle tube 4, start the servo motor 6 to work, drive the cam 7 to rotate. At this time, the swing rod 8 can be driven to generate a swinging displacement, and then the lifting plate 9 is pulled to reciprocate up and down in the housing 5, and then the scraper 11 fixed to the sliding rod 10 is driven to reciprocate, driving the cleaning thimble 12 to reciprocally insert into the oil injection needle tube 4, pressing the blocked e-liquid in the oil injection needle tube 4 downward to achieve the cleaning effect of the oil injection needle tube 4. At the same time, open the oil discharge valve port 20 to squeeze and discharge the remaining e-liquid in the oil guiding cavity 2. The cleaning is convenient and the cleaning effect is good; when the oil injection needle tube 4 moves downward and inserts into the e-cigarette oil storage shell for oil injection, the pressing plate 15 first abuts against the side wall of the opening end of the oil storage shell. At this time, the abutting spring 16 is compressed and contracted to generate an elastic force. Using its elastic force, the pressing plate 15 can be abutted against the oil storage shell for positioning and fixing, so that the oil injection needle tube 4 can be accurately inserted into the oil storage shell to prevent the oil storage shell from shifting.
