AI Technical Summary

Technical Problem

The connection between the e-liquid cartridge and the e-cigarette cartridge in existing electronic cigarettes is unstable, resulting in a weak connection that is prone to loosening or detachment.

Method used

A design is created with two opposing insertion slots on the bottom of the oil cartridge shell. The mouthpiece forms an insertion plate with protrusions and positioning grooves. The oil cartridge and the e-cigarette cartridge are stably connected through the cooperation of the insertion slots and the T-shaped insertion plate. The connection is further secured by the combination of the inverted buckle and the positioning groove.

Benefits of technology

This achieves a stable connection between the e-liquid cartridge and the e-cigarette cartridge, preventing loosening and detachment, and ensuring smooth flow of e-liquid and a secure connection.

Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to a fixing structure for electronic cigarette cartridges. Background Technology

[0002] Electronic cigarette cartridges typically use e-liquid cartridges to fill with e-liquid. Once the cartridge is filled with e-liquid, how to achieve a stable connection between the e-liquid and the cartridge is a problem that designers need to consider. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a fixing structure for electronic e-cigarette cartridges, which can achieve a stable connection between the cartridge and the e-cigarette cartridge.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] It includes a fuel cartridge and a cigarette cartridge. The fuel cartridge includes a fuel cartridge shell; the cigarette cartridge includes a mouthpiece. The fuel cartridge shell forms two oppositely opening insertion slots. The mouthpiece forms an insertion plate corresponding to the insertion slots. After the two sides of the insertion plate are inserted into the insertion slots, a stable connection is formed between the cigarette cartridge and the fuel cartridge.

[0006] The insertion slots are protruding from the bottom of the oil cartridge casing; an inverted buckle is provided at the bottom of the oil cartridge casing between the two insertion slots.

[0007] The insertion plate has protruding strips that fit into the insertion slot, forming T-shaped fixation bone positions on both sides.

[0008] The plug-in board is provided with a positioning groove corresponding to the inverted design.

[0009] The positioning grooves are provided in two positions on the front and back of the plug-in plate along the plug-in direction.

[0010] The oil cartridge and e-cigarette cartridge of this invention can form a stable connection through the insertion groove and T-shaped insertion plate. The inverted buckle and positioning groove also ensure that the oil cartridge will not easily slip out of the insertion plate after connection. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings:

[0012] Figure 1 This is one of the three-dimensional views of the oil cartridge 1 and smoke cartridge 22 in a semi-assembled state of this utility model;

[0013] Figure 2 This is the second perspective view of the oil cartridge 1 and smoke cartridge 2 in a semi-assembled state of this utility model;

[0014] Figure 3 This is a cross-sectional view of the fuel cartridge 1 and the cigarette cartridge in a semi-assembled state.

[0015] Figure 4This is a cross-sectional view of the oil cartridge 1 and smoke cartridge 2 in their assembled state.

[0016] Figure 5 This is a cross-sectional view of the oil cartridge 1 and smoke cartridge 2 in their assembled state. Detailed Implementation

[0017] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate 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.

[0018] like Figure 1-5 As shown, this utility model includes an oil cartridge 1 and a cigarette cartridge 2. The oil cartridge 1 includes an oil cartridge shell 11; the cigarette cartridge 2 includes a mouthpiece 21.

[0019] The bottom of the fuel cartridge casing 11 protrudes to form two oppositely opening insertion slots 111; an inverted buckle 112 is provided at the bottom of the casing between the two insertion slots 111.

[0020] The suction nozzle 21 forms an insertion plate 211 corresponding to the insertion groove 111; a protruding strip 212 protrudes from the insertion plate 211 and fits into the insertion groove 111, forming T-shaped fixation positions on both sides. At the same time, a positioning groove 213 is provided on the insertion plate 211 corresponding to the inverted buckle 112. Two positioning grooves 213 are provided on the insertion plate 211 along the insertion direction, one in front and one behind.

[0021] When the two sides of the insertion plate 211 are inserted along the insertion slots 111, the protrusion 212 can limit the position of the insertion plate 211 between the two insertion slots 111, preventing it from wobbling left and right. Simultaneously, when the buckle 112 engages with the positioning groove 213 at the end of the insertion plate 211, the oil cartridge 1 and the e-liquid cartridge 2 can achieve initial engagement; if insertion continues, the oil cartridge 1 will gradually open, allowing the e-liquid inside to flow into the e-liquid cartridge 2. As the insertion plate 211 continues to be inserted, until the other positioning groove 213 engages with the buckle 112, the oil cartridge 1 and the e-liquid cartridge 2 achieve full engagement. At this point, the oil cartridge 1 is fully open. After insertion, the engagement of the positioning groove 213 and the buckle 112 limits the groove orientation of the oil cartridge 1 and the e-liquid cartridge 2; while the protrusion 212 limits the vertical position between the two grooves. Therefore, a stable connection is formed between the oil cartridge 1 and the e-liquid cartridge 2.

[0022] The structure of the remaining parts of this utility model, such as the oil cartridge and the smoke cartridge, 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.
