Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an e-liquid filling structure for an electronic e-liquid bottle. Background Technology

[0002] In existing e-cigarettes, e-liquid is typically stored in a bottle; after the atomizer chamber and e-liquid are assembled, the bottle supplies e-liquid to the atomizer chamber. To facilitate e-liquid supply after assembly, the bottle usually has a thin film-like seal at the wicking hole. During assembly, the wicking tube of the atomizer chamber punctures the film, opening the wicking hole in the bottle.

[0003] Currently, some methods involve making the tip of the oil guide tube into a pointed shape to pierce the membrane; however, this structure of the oil guide tube can easily cause injury to the hand during factory operations and consumer use.

[0004] In addition, some designs feature snowflake-shaped or cross-shaped cuts at the film position. The thin film is stretched by assembling an oil guide tube, causing it to tear in the middle and open the oil inlet. However, in this method, the film deformation length is difficult to determine, and it increases the advance stroke of the oil guide tube. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an oil filling structure for an electronic e-liquid bottle; the oil guide hole can be opened accurately without having to make the top of the oil guide tube into a pointed shape.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0007] The device includes an oil bottle and an atomizing chamber. The bottom of the oil bottle is fitted with sealing silicone to isolate the internal oil storage chamber from the outside. An oil guide tube is installed at the top of the atomizing chamber, extending through the sealing silicone into the oil storage chamber. The sealing silicone consists of an upper silicone sheet, a lower silicone sheet, and a steel sheet. The upper silicone sheet, steel sheet, and lower silicone sheet are stacked sequentially. An oil guide hole is provided on the upper silicone sheet corresponding to the oil guide tube. A sealing thin film is provided on the lower silicone sheet corresponding to the oil guide hole. A non-closed shearing hole is provided on the circumference of the steel sheet corresponding to the oil guide hole.

[0008] The diameter of the oil guide hole of the upper silicone sheet, the outer diameter of the sealing film of the lower silicone sheet, and the diameter of the shearing hole of the steel sheet are all equal.

[0009] The shearing hole in the steel sheet is formed by a notch in the circumferential direction, and the ratio of the circumferential length of the notch to the remaining part is 1:3.

[0010] This invention utilizes the cooperation of an oil guide tube and a steel sheet. During the advancement of the oil guide tube, the steel sheet can be used to partially cut the sealing film, opening the oil guide hole. During this opening process, the steel sheet's fixing effect ensures that the lower silicone sheet does not undergo axial deformation; the advancement of the oil guide tube can be predicted and controlled. After the sealing film is partially cut, the remaining portion adheres to the lower silicone sheet, preventing the sealing film from entering the e-liquid. This invention eliminates the need for a pointed tip on the oil guide tube, avoiding the problems of sharp points that could cause injury during factory operations and consumer use.

[0019] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate the understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0020] like Figures 1 to 7 As shown, the e-liquid bottle filling structure of this utility model includes an oil bottle 1 and an atomizing chamber 2.

[0021] The oil bottle 1 includes an inner shell 12 and an outer shell 13. The inner shell 12 forms an atomization channel in the center of the oil bottle 1. The outer shell 13 and the top of the inner shell 12 are connected to form a mouthpiece 14 that communicates with the atomization channel. A sealing silicone 11 is sealed between the bottom of the outer shell 13 and the inner shell 12. The outer shell 13, the inner shell 12, the sealing silicone 11 and the mouthpiece 14 enclose and form an oil storage cavity.

[0022] An oil guide tube 21 is provided at the top of the atomizing chamber 2. The oil guide tube 21 can pass through the sealing silicone 11 and extend into the oil storage chamber.

[0023] See Figure 2 , 3 As shown in Figures 4 and 6, the sealing silicone 11 consists of an upper silicone sheet 111, a lower silicone sheet 113, and a steel sheet 112. The upper silicone sheet 111, the steel sheet 112, and the lower silicone sheet 113 are stacked sequentially from top to bottom. The upper silicone sheet 111 has an oil guide hole 1111 corresponding to the oil guide tube 21, the lower silicone sheet 113 has a sealing thin film 1131 corresponding to the oil guide hole 1111, and the steel sheet 112 has a non-closed shear hole 1121 on its circumference corresponding to the oil guide hole 21.

[0024] Specifically, the diameter of the oil guide hole 1111 of the upper silicone sheet 111, the outer diameter of the sealing thin film 1131 of the lower silicone sheet 113, and the diameter of the shearing hole 1121 of the steel sheet 112 are equal.

[0025] The position where the steel sheet 112 forms the shear hole 1121 forms a notch 1122 in the circumferential direction. The ratio of the circumferential length of the notch 1122 to the remaining part is 1:3; that is, in the circumferential direction, there is a quarter of the position above the sealing adhesive 1131 where the steel sheet 112 is not provided.

[0026] like Figures 4 to 7 As shown, the oil guide tube 21 of the atomizing chamber 2 is inserted into the oil guide hole 1111 of the sealing silicone 11. Upon contact with the sealing film 1131 and further insertion, the steel plate 112 above the sealing film 1131 presses against the edge of the sealing film 1131, preventing deformation of the corresponding lower silicone sheet 113. Further insertion of the oil guide tube 21, combined with the steel plate 112 (the upward force F2 of the oil guide tube 21 and the downward force F1 of the steel plate 112 work together), cuts off the edge of the sealing film 11 where the steel plate 112 is located (i.e., the steel plate 112 forms a shearing notch 1121); the remaining portion (corresponding to the notch 1121 of the steel plate 112) is not cut off. Then, under the action of the oil guide tube 21, the sealing film 1131 is pushed open; the oil guide hole 1111 opens.

[0027] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining parts are not related to the implementation of the above technical solution, nor are they limited to those shown in the figure; they will not be described in detail here.
