Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette that connects to a circuit by activating an oil bottle. Background Technology

[0002] Electronic cigarettes atomize e-liquid through an atomizer coil when e-liquid is supplied. If the e-liquid supply is not timely or the atomizer coil is powered on without e-liquid, it is easy to burn out the atomizer coil.

[0003] Therefore, how to ensure that the atomizer coil can be powered on when the e-liquid is supplied is a problem that designers need to consider. Utility Model Content

[0004] The technical problem solved by this invention is to provide an electronic cigarette that connects the circuit by activating the oil bottle; ensuring that the atomizer core can only be powered on when the oil circuit is activated and supplying oil, thus avoiding the problem of dry burning of the atomizer core.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0006] The electronic cigarette includes a cartridge assembly, a device assembly, and an e-liquid bottle. The device assembly is mounted below the cartridge assembly. Two spring pins, one long and one short, protrude from below the cartridge assembly. The device assembly contacts the long spring pin. The device assembly and the e-liquid bottle can be assembled together from the left and right sides. When the e-liquid bottle is assembled, it is first assembled with the device assembly. As the e-liquid bottle continues to be assembled with the cartridge assembly, it drives the device assembly to simultaneously contact the short spring pin, thereby connecting the power supply circuit to the cartridge assembly.

[0007] The side of the cigarette rod assembly shell that contacts the oil bottle has protruding protrusions; the oil bottle is correspondingly provided with barbs; during the oil bottle assembly process, the barbs cooperate with the protrusions; through the cooperation of the barbs and protrusions, the cigarette rod assembly and the cigarette cartridge assembly are further assembled.

[0008] The protrusion is located near the bottom of the outer shell of the cigarette rod assembly; the barb is correspondingly located near the bottom of the outer shell of the oil bottle.

[0009] The length difference between the bottom of the two protruding pins of the cartridge assembly is equivalent to the stroke required for the oil bottle and cigarette rod assembly to be fully assembled with the cartridge assembly.

[0010] This invention relates to an electronic cigarette with a pre-assembled device assembly and cartridge assembly, where the long spring pins of the device assembly and cartridge assembly are in contact. During the assembly of the e-liquid bottle, the interlocking structure between the bottle and the device assembly drives further assembly of the device assembly and cartridge assembly. Simultaneously with the complete assembly of the e-liquid bottle and cartridge assembly, the device assembly and cartridge assembly are also fully assembled; the short spring pin of the cartridge assembly also makes contact with the device assembly at the same time, allowing the atomizer core circuit within the cartridge assembly to be activated when the switch is turned on. This synchronization between the e-liquid bottle and the atomizer core circuit prevents the atomizer core from being burned out due to dry burning when no e-liquid is supplied.

[0016] Figure 5 This is an exploded three-dimensional view of the electronic cigarette of this utility model. 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 Figures 1 to 5 As shown, the electronic cigarette of this utility model includes a cartridge assembly 1, a cigarette rod assembly 2, and an oil bottle 3; two spring pins 11 and 12 of different lengths are protruding below the cartridge assembly 1 at the position where the cigarette rod assembly 2 is assembled; the cigarette rod assembly 2 is pre-assembled below the cartridge assembly 1; at this time, the cigarette rod assembly 2 is in contact with the long spring pin 11.

[0019] The cigarette rod assembly 2 and the oil bottle 3 can be assembled as a single unit from the left and right sides. Specifically, the side of the cigarette rod assembly shell 21 that contacts the oil bottle 3 has a protrusion 22; the oil bottle shell 31 is correspondingly provided with a barb 32; the protrusion 22 is located near the bottom of the cigarette rod assembly shell 21; the barb 32 is correspondingly located near the bottom of the oil bottle shell 31.

[0020] During the assembly process of the oil bottle 3, the barb 32 first engages with the protrusion 22, thus assembling the oil bottle 3 and the e-cigarette assembly 2 into one unit. As the oil bottle 3 continues to complete the assembly with the e-cigarette cartridge assembly 1, it drives the further assembly of the e-cigarette assembly 2 and the e-cigarette cartridge assembly 1. This allows the e-cigarette assembly 2 to simultaneously contact the short spring pin 12, enabling the power supply circuit to be connected to the e-cigarette cartridge assembly 1.

[0021] To ensure the synchronous assembly of the oil bottle 3, the e-cigarette assembly 2, and the e-cigarette cartridge assembly 1, the length difference between the two protruding pins 11 and 12 extending from the bottom of the e-cigarette cartridge assembly 1 is exactly the same as the stroke of the oil bottle 3 and the e-cigarette assembly 2 when they are assembled into the oil bottle 3 as when they are assembled into the e-cigarette cartridge assembly 1.

[0022] In this invention, during production and shipment, the cartridge assembly 1 is not equipped with the oil bottle 3, and the e-cigarette assembly 2 only contacts the long spring pin 11, failing to form a passage. Simultaneously, when the oil bottle 3 is assembled with the cartridge assembly 1, the e-cigarette assembly 2 is brought into contact with the two spring pins 11 and 12 to form a passage, allowing for inhalation after the child lock is released.

[0023] 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 aforementioned scheme; they will not be described in detail here.
