Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic e-liquid bottle structure with a mechanical child lock. Background Technology
[0002] Electronic cigarettes typically extend their usage time by refilling e-liquid from a bottle. For ease of use, the bottle usually connects to the e-liquid reservoir via a simple plug-in connection. However, due to the small size of both the e-cigarette and the e-liquid bottle, they are easily accessible to children, who may accidentally insert them into the device. Therefore, preventing children from opening the e-liquid bottle is a design consideration. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an electronic e-liquid bottle structure with a mechanical child lock to prevent the bottle from being accidentally opened and used by children after they come into contact with it.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] The structure includes an oil bottle and a knob lock; the oil bottle includes an outer shell and a base, with the base located at the lower end of the outer shell; a knob lock is installed inside the outer shell and outside the base; the knob lock, when engaged with the outer shell, isolates the outside of the base from the outside environment.
[0006] The outer shell of the oil bottle forms a barrel-shaped inner shell along the axial direction; the base of the oil bottle forms a corresponding base hole; the outer shell of the oil bottle and the base of the oil bottle cooperate to form an axial channel.
[0007] The oil bottle shell has two radially corresponding inverted L-shaped locking grooves located below the oil bottle base.
[0008] The rotary lock includes a child lock base, a spring, and a child lock bracket;
[0009] The child lock base is composed of a disc-shaped base body. A guide post protrudes axially from the center of the inner side of the disc-shaped base body, and a protruding ring is formed. The protruding ring is fitted over the guide post, and a gap space is formed between the protruding ring and the guide post. A strip-shaped rotating handle protrudes from the outer side of the disc-shaped base body. Two buckles protrude radially and symmetrically from the side of the disc-shaped base body. The buckles can be engaged in the buckle groove.
[0010] The child lock bracket is composed of two cylinders of different diameters connected together; the larger diameter cylinder is located at the bottom and can be inserted into the space between the convex ring and the guide post; the axial dimension of the child lock bracket is smaller than the axial dimension of the guide post.
[0011] The spring is sleeved outside the guide post and placed inside the cylinder of the child lock bracket;
[0012] A screw is attached to the top of the guide post; the screw limits the axial position of the smaller cylindrical tip to not exceed the top of the guide post.
[0013] When the buckle deviates from the circumferential direction of the buckle groove and the knob lock is inserted into the outer shell of the oil bottle, the step formed by the two cylinders of the child lock bracket first abuts against the base of the oil bottle, and the smaller diameter cylinder of the child lock bracket is inserted into the channel.
[0014] When the knob lock is further inserted and the bottom of the larger diameter cylinder of the child lock bracket presses against the inner side of the disc-shaped main body, the buckle and the locking groove are in the same position in the axial direction. After the knob is rotated, the buckle is embedded into the circumferential part of the locking groove. When the knob is rotated further, the buckle presses against the end of the circumferential part of the locking groove. At this time, the axial pressure applied to the knob lock is removed, and the spring pushes the buckle into the end of the axial part of the locking groove, thus achieving a stable fit between the knob lock and the oil bottle shell.
[0015] This invention features a knob lock at the bottom of the oil bottle casing, preventing children from opening the bottle and inserting it into an electronic cigarette device. The knob lock incorporates a spring, and the child lock bracket and base allow for axial relative movement. A child lock buckle is located on the outer side of the child lock base to secure the oil bottle, thus locking it. The entire structure is simple and effectively prevents children from opening the oil bottle. Attached Figure Description
