[0026] See appendix Figure 1-5 The image shows a sliding-cover child-locking e-cigarette cartridge. The cartridge 1 has a shell 2, an oil reservoir 20 inside the shell 2, and an oil inlet communicating with the oil reservoir 20. The oil inlet is equipped with an oil plug 21. A sliding cover 3 is installed on the shell 2, positioned above the oil plug 21. The sliding cover 3 controls the obstruction of the oil plug 21 by sliding. A spring piece 22 is provided on the shell 2, and a hook 220 is provided on the spring piece 22. The sliding cover 3 has a hook groove 31. The hook 220 connects with the hook groove 31 to lock the sliding cover 3 in place of the oil plug 21. Pressing the spring piece 22 disengages the hook 220 from the hook groove 31, and the sliding cover 3 slides to expose the oil plug 21.
[0027] Under normal conditions, the refill plug 21 blocks the refill port, while the sliding cover 3 covers the top of the refill plug 21. Simultaneously, the sliding cover 3 is locked by the hook 220 on the spring 22 to prevent accidental disengagement by children. When refilling is needed, pressing the spring 22 disengages the hook 220 from the groove 31, releasing the lock on the sliding cover 3. Then, the sliding cover 3 slides relative to the housing 2, exposing the refill plug 21, which the user can then open to refill e-liquid. This child lock structure is simple, stable, reliable, and easy to operate.
[0028] In some embodiments, the housing 2 has two longitudinal grooves 24 located on both sides of the oil filler plug 21; the sliding cover 3 has two slide rails 32 on both sides, each slide rail 32 being slidably embedded in one of the grooves 24. The two grooves 24 are arranged parallel to each other on both sides of the oil filler plug 21, and the slide rails 32 on both sides of the sliding cover 3 are adapted to the grooves 24, with each slide rail 32 embedded in the corresponding groove 24. The slide rails 32 move within the grooves 24 to achieve stable sliding of the sliding cover 3. The sliding cover 3 opens upwards, exposing the oil filler plug 21; the sliding cover 3 closes downwards, covering the oil filler plug 21.
[0029] In order to control the sliding stroke of the sliding cover 3, the sliding cover 3 can be terminated when it reaches the point of blocking or exposing the oil plug 21, so as to prevent the sliding cover 3 from sliding off and to enhance the guidance for the user to operate the sliding cover 3. A matching stroke limit structure can be designed on the sliding cover 3 and the housing 2.
[0030] Specifically, each of the slide rails 32 has a travel block 320 at its bottom end, and each of the slide grooves 24 has a limiting protrusion 240 at its top end. When the sliding cover 3 slides upward to the point where the oil filler plug 21 is exposed, the limiting protrusion 240 abuts against the travel block 320 to terminate the upward travel of the sliding cover 3. When the sliding cover 3 moves upward, the slide rail 32 moves upward along the slide groove 24. When the oil filler plug 21 is exposed, the travel block 320 on the slide rail 32 is just abutted and blocked by the limiting protrusion 240, and the sliding cover 3 cannot continue to move upward. This limits and guides the upward movement of the sliding cover 3 to expose the oil filler plug 21.
[0031] Furthermore, a limiting platform 25 is formed on the top of the oil inlet on the housing 2, and a limiting plate 33 is provided at the upper end of the sliding cover 3; when the sliding cover 3 descends to the position of blocking the oil plug 21, the limiting platform 25 and the limiting plate 33 abut against each other to terminate the downward stroke of the sliding cover 3. When the sliding cover 3 descends to the position of blocking the oil plug 21, the limiting plate 33 is blocked by the limiting platform 25, and the sliding cover 3 cannot continue to descend, thereby limiting and guiding the downward movement of the sliding cover 3.
[0032] In some embodiments, the spring piece 22 is disposed below the oil inlet, the fixed end of the spring piece 22 is connected to the housing 2, the movable end of the spring piece 22 extends upward, and the inner side of the movable end has a deformation space 23 so that the movable end can be pressed and elastically deformed; the hook 220 is disposed on the movable end.
[0033] The fixed end of the lower part of the spring piece 22 is connected to the housing 2, and its upper part forms a movable end that can be pressed and elastically deformed. The hook 220 is set on the movable end. Under normal conditions, the hook 220 cooperates with the hook groove 31 on the sliding cover 3 to lock the sliding cover 3. When oil needs to be added, force is applied to press the movable end of the spring piece 22 inward, and the movable end deviates towards the deformation space 23. The hook 220 disengages from the hook groove 31, thereby releasing the lock on the sliding cover 3. At this time, the sliding cover 3 can be operated to slide upward to expose the oil filling plug 21.
[0034] Specifically, the hook 220 is disposed on the outer side of the movable end, and the hook 220 protrudes outward; the groove 31 is disposed on the lower part of the inner side of the sliding cover 3, and the groove 31 has a slot facing the hook 220. The outwardly protruding hook 220 enters the groove 31 through the slot, and the bottom wall of the hook abuts against the bottom wall of the groove 31, thereby restricting the upward movement of the sliding cover 3 and locking the sliding cover 3; when the movable end of the spring piece 22 is pressed, the hook 220 moves inward and disengages from the groove 31 through the slot, thereby releasing the lock on the sliding cover 3.
[0035] In some embodiments, the outer surface of the sliding cover 3 is provided with anti-slip textures, such as multiple transversely distributed ridges. This is used to enhance the friction of the sliding cover 3 surface, which helps to improve the stability when operating the sliding cover 3.
[0036] An electronic atomizing device is provided, including a main unit, the electronic atomizing device further including a cartridge 1 as described in any of the preceding claims, the cartridge 1 being assembled and connected to the main unit.
[0037] In summary, the improved cartridge uses a sliding cover to block the refill plug, and the sliding cover is locked by a spring, which can effectively prevent children from accidentally touching it. The child lock structure is simple and easy to operate.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
