Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an automatic activation and shutdown structure for refilling e-liquid cartridges in an atomizer. Background Technology

[0002] Electronic cigarettes typically replenish e-liquid to the atomizing component (such as the atomizer) by replacing the cartridge. Therefore, how to close or open the e-liquid outlet when replacing the cartridge is a design consideration. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an automatic activation and shutdown structure for replenishing e-liquid cartridges in an atomizer; the e-liquid cartridge outlet can be automatically opened or closed when the cartridge is replaced to control whether e-liquid is supplied to the atomizer.

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

[0005] The automatic activation and shutdown structure includes a cartridge and an atomizer; the bottom of the cartridge and the top of the atomizer are connected by a sliding groove structure to allow for left-right sliding assembly or disassembly; an oil outlet and a sliding switch are provided at the bottom of the cartridge, which can open the oil outlet when the atomizer is assembled with the cartridge, and close the oil outlet when the atomizer is disassembled from the cartridge; the atomizer is provided with an oil inlet corresponding to the oil outlet.

[0006] The oil cartridge has a U-shaped protrusion extending from the bottom periphery, and a U-shaped groove is recessed on the inner side of the U-shaped part; the atomizer has a corresponding U-shaped protrusion; and a slide rail is formed around the U-shaped protrusion that corresponds to the U-shaped groove.

[0007] A sliding switch is provided on the inner side of the bottom surface of the cartridge, and a switch actuation groove is provided on the bottom surface; the actuation block of the sliding switch protrudes from the bottom surface and is provided in the actuation groove; the atomizer is provided with a receiving groove corresponding to the actuation block in the actuation groove; when the cartridge and the atomizer are assembled to the end of their stroke, the actuation block is engaged in the receiving groove and, as the assembly continues, drives the sliding switch to slide open the oil outlet, the oil outlet and the oil inlet correspond to and communicate with each other; when the cartridge and the atomizer are disassembled to the end of their stroke, the actuation block in the receiving groove drives the sliding switch to slide close the oil outlet as the disassembly and assembly continue.

[0008] When initially assembling the e-liquid cartridge, the cartridge switch is in the closed state. When the user slides the cartridge sideways into the atomizer, the cartridge switch, upon contact with the atomizer, is pushed back by the interference between the atomizer and the switch. This continues until the force applied during cartridge assembly exceeds the interference force, at which point the switch slightly springs up, passes the atomizer interference point, and slides into the silicone slot (a receiving slot to prevent free movement after assembly). This allows the cartridge switch to open simultaneously with cartridge assembly, enabling e-liquid replenishment. To stop refilling, the user simply holds the cartridge and pushes it out in the opposite direction of insertion. As the cartridge slides out, the interference between the atomizer and the switch applies a counterforce, closing the cartridge switch and preventing e-liquid leakage after removal. This invention achieves automatic switching between atomizer and cartridge assembly / disassembly, automatically activating or deactivating the e-liquid supply mechanism. Attached Figure Description

[0014] 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.

[0015] like Figures 1 to 4 As shown, the activation and deactivation structure of the atomizer refill cartridge of this utility model includes a cartridge 1 and an atomizer 2. A U-shaped portion 11 protrudes from the periphery of the bottom surface of the cartridge 1, and a U-shaped groove 12 is recessed on the inner side of the U-shaped portion 11; the atomizer 2 correspondingly protrudes a U-shaped protrusion 21; a slide rail 22 is formed around the periphery of the U-shaped protrusion 21, corresponding to the U-shaped groove 12. By matching the U-shaped groove 12 with the slide rail 22, the bottom of the cartridge 1 and the top of the atomizer 2 can be assembled or disassembled by sliding left and right.

[0016] An oil outlet 13 is provided at the bottom of the e-liquid cartridge 1, and an oil inlet 23 is provided in the atomizer 2 corresponding to the oil outlet.

[0017] A sliding switch 13 is provided on the inner side of the bottom surface of the oil cartridge 1, and a switch toggle groove 14 is provided on the bottom surface; the toggle block 15 of the sliding switch 16 protrudes from the bottom surface and is provided in the toggle groove 14; the atomizer 2 is provided with a receiving groove 24 corresponding to the toggle block 15 in the toggle groove 14.

[0018] When the cartridge 1 and atomizer 2 are assembled to the end of their stroke, the actuating block 15 is engaged in the receiving groove 24 and, as the assembly continues, drives the sliding switch 16 to slide open the oil outlet 13, which corresponds to and connects with the oil inlet 23. When the cartridge 1 and atomizer 2 are disassembled to the end of their stroke, the actuating block 14 in the receiving groove 24 drives the sliding switch 16 to slide close the oil outlet 13 as the disassembly and assembly continue.

[0019] 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.
