Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette cartridge technology, specifically a child lock structure for a cartridge and an electronic cigarette. Background Technology

[0002] In the e-cigarette industry, the refilling structure of refillable cartridges is crucial to safety and user experience. Currently, most refillable cartridges on the market use a silicone stopper to seal the cartridge, but this method has significant drawbacks: firstly, when a child gets hold of the cartridge, the silicone stopper can be easily pulled open, allowing e-liquid to leak out and posing a risk of accidental ingestion; secondly, when the silicone stopper is opened to refill, the e-liquid in the cartridge comes into direct contact with the air, potentially contaminating the e-liquid and affecting user experience.

[0003] Regarding the safety issues of using e-liquid cartridges, there are relevant child lock solutions in the existing technology. For example, a Chinese patent proposes an atomizer and e-cigarette with a child lock, patent publication number: CN221430320U. The above patent implements the child lock function by using an oil sealing component in conjunction with a child lock device with a sliding structure and a shielding component, so as to avoid problems such as e-liquid leakage caused by accidental operation.

[0004] However, the patented solution still has shortcomings. Its child lock relies on the cooperation of mechanical structures such as sliding and blocking, and the design is relatively complex. Moreover, the solution mainly focuses on the mechanical prevention of accidental operation of the child lock. It lacks targeted optimization design for the key issue that affects user experience: "reducing excessive contact between e-liquid and air to reduce the probability of contamination during the filling process and daily use." It cannot effectively solve the problem of e-liquid being easily contaminated.

[0005] In order to simultaneously achieve the technical effects of "preventing e-liquid from leaking out and being accidentally ingested by children" and "reducing the contact area between e-liquid in the cartridge and air, lowering the probability of contamination, and improving the user experience", we have proposed a child lock structure for the cartridge and an electronic cigarette. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a child lock structure for cigarette cartridges and an electronic cigarette, thus solving the aforementioned problems.

A silicone rivet is installed inside the mounting hole on one side of the top of the oil-filled silicone pad, and an oil-filled silicone plug is inserted into the mounting hole on the other side of the oil-filled silicone pad.

[0014] Preferably, a sealing plug is fixedly installed at the bottom of the silicone injection plug corresponding to the position of the injection hole on the silicone injection plug, and the injection hole on the silicone injection plug has an injection groove in the shape of a cross, and the valve inside the injection hole is deformable.

[0015] Compared with the prior art, this utility model provides a child lock structure for a cigarette cartridge and an electronic cigarette, which has the following beneficial effects:

[0016] 1. The child lock structure of this e-cigarette cartridge and e-cigarette includes an e-liquid silicone filling device, silicone rivets, and an e-liquid silicone plug. The e-liquid silicone filling device has a cross-shaped e-liquid filling groove and a deformable valve. The sealing plug at the bottom of the e-liquid silicone plug is precisely matched with the e-liquid filling hole.

[0034] Furthermore, a child lock structure for a cigarette cartridge is provided. The child lock structure includes an oil-filled silicone 8, a silicone rivet 9, and an oil-filled silicone plug 10. The oil-filled silicone 8 is snapped onto one side of the top of the oil tank 1, and mounting holes for auxiliary fixing are provided on both sides of the top of the oil-filled silicone 8. The silicone rivet 9 is installed inside the mounting hole on one side of the top of the oil-filled silicone 8, and the oil-filled silicone plug 10 is inserted into the mounting hole on the other side of the oil-filled silicone 8.

[0035] Furthermore, a sealing plug is fixedly installed at the bottom of the oil injection silicone plug 10 corresponding to the position of the oil injection hole on the oil injection silicone 8, and the oil injection hole on the oil injection silicone 8 has a cross-shaped oil injection groove 18 inside, and the valve inside the oil injection hole is deformable.

[0036] Example

[0037] Example 1: The oil tank 1 is the core component for oil storage. Its bottom is sealed with the oil tank base 3 through the oil tank sealing silicone 2. The oil-absorbing cotton 4 of the base is filled inside the oil tank base 3 to absorb residual e-liquid. The oil-filling silicone 8 on the top of the oil tank 1 is fixed to the oil-filling silicone plug 10 by silicone rivets 9 to realize the child lock function.

The sealing ring 14 further enhances the sealing between the cover and the oil tank. When filling with oil, the filling silicone plug 10 must be pulled out first, and then the cross-shaped filling groove 18 is deformed by inserting the filling tube. After filling with oil, it can be plugged back to restore the seal. The modular design simplifies the assembly process. The combination of the groove window and the cotton layer optimizes the atomization effect. It is suitable for repeated filling scenarios with high atomization efficiency requirements, taking into account both practicality and ease of maintenance.

[0039] Structural Description

[0040] Oil tank 1, as the core component for storing e-liquid in the e-liquid cartridge, has its bottom filled with oil tank sealing silicone 2, and an oil tank base 3 is also inserted and installed at the bottom. The interior carries the atomizing components, providing a basic carrier for e-liquid storage and atomizing component assembly.

[0041] Oil tank sealing silicone 2 is inserted and installed between oil tank 1 and oil tank base 3, filling the gap between the two to play a sealing role and prevent the e-liquid in oil tank 1 from leaking from the connection between the bottom and oil tank base 3.

[0042] Oil tank base 3 is inserted and installed at the bottom of oil tank 1. Base oil-absorbing cotton 4 is inserted and installed inside.

[0043] The base absorbent cotton 4 is inserted into the inside of the oil tank base 3 to absorb the residual e-liquid inside the oil tank base 3, prevent residual e-liquid from leaking, and maintain the cleanliness and sealing of the inside of the e-liquid cartridge.

[0044] Electrode 5, two sets in total, are fixedly installed at the bottom of the oil tank base 3 at the position corresponding to the atomizing component. They are used to enable the circuit connection between the e-liquid cartridge and the external host, supply power to the heating wire 17 in the atomizing component, and ensure the power demand for e-liquid atomization.

[0045] Electrode ring 6 is sleeved and installed on the outer wall of each group of electrodes 5 to seal the gap between the electrode 5 and the oil tank base 3, and to prevent e-liquid from leaking from the connection between the electrode 5 and the oil tank base 3.

[0046] Magnet 7 is fixedly installed on both sides of the bottom of the oil tank base 3. It helps to fix the e-liquid cartridge to the external host through magnetic adsorption, improves the stability of the e-liquid cartridge after installation, and prevents it from loosening during use.

[0047] The silicone 8 is snap-fitted onto the top side of the oil tank 1. It has mounting holes on both sides of its top for auxiliary fixing. A silicone rivet 9 is installed in the mounting hole on one side, and a silicone plug 10 is inserted into the mounting hole on the other side. It also has an oil filling hole with an oil filling groove 18. It is the core load-bearing component of the child lock structure.

[0048] Silicone rivet 9 is installed inside the mounting hole on one side of the top of the oil-filling silicone 8. It is used to fix the oil-filling silicone 8 to the top of the oil tank 1 and prevent the oil-filling silicone 8 from shifting or falling off during use.

[0049] The silicone plug 10 is inserted into the mounting hole on the other side of the silicone 8. A sealing plug is fixedly installed at the bottom of the silicone 8 corresponding to the position of the oil filling hole. This is used to seal the oil filling hole, realize the child lock anti-accidental opening function, and prevent e-liquid from leaking from the oil filling hole.

[0050] Insulating silicone 11 is a component of the atomizing assembly. The top of the insulating silicone 11 is snapped with the atomizing core bracket 12, which serves as insulation to prevent short circuits in the internal circuitry of the atomizing assembly and ensure electrical safety during the atomization process.

[0051] The atomizing core bracket 12 is snapped onto the top of the insulating silicone 11. The heating wire 17 is fixedly installed inside it, and the atomizing core cover 13 is sleeved on the outside. The inner cotton 16 is inserted between the atomizing core bracket 12 and the heating wire 17, and the outer cotton 15 is inserted between the atomizing core cover 13 and the outer cotton 15. It is the core of bearing and connecting the various components of the atomizing assembly.

[0052] The atomizing core cover 13 is fitted onto the outside of the atomizing core bracket 12. Its outer wall surface has several slots and windows arranged in a ring array at equal intervals. Two sets of sealing rings 14 are fitted onto the outer wall surface at the end, which cooperate with the atomizing core bracket 12 to form an atomization space. The slots and windows are used to assist the flow of e-liquid and improve atomization efficiency.

[0053] There are two sets of sealing rings 14, which are fitted and installed on the outer wall of the end of the atomizing core cover 13 to seal the gap between the atomizing core cover 13 and the oil tank 1 and other components, so as to prevent the leakage of e-liquid or atomized aerosol.

[0054] The outer cotton 15 is inserted and installed between the atomizing core cover 13 and the atomizing core bracket 12, and is sleeved on the outside of the atomizing core bracket 12. It is used to absorb the e-liquid in the oil tank 1, continuously supply oil to the heating wire 17, and at the same time assist in the uniform atomization of the e-liquid.

[0055] The inner cotton 16 is inserted and installed between the heating wire 17 and the atomizing core bracket 12, and is sleeved on the outside of the heating wire 17. It is used to wrap the heating wire 17, absorb e-liquid and transfer it to the surface of the heating wire 17, and at the same time buffer the temperature shock of the heating wire 17 during operation to protect the heating wire 17.

[0056] The heating wire 17 is fixedly installed inside the atomizing core bracket 12. After the heating wire 17 is connected to the external host through the electrode 5, it heats up and atomizes the e-liquid transferred by the inner cotton 16. It is the core functional component for e-liquid atomization.

[0057] The e-liquid filling groove 18 is located inside the e-liquid filling hole on the e-liquid silicone 8. It is cross-shaped and the valve inside the e-liquid filling hole is deformable. When filling e-liquid, the external e-liquid tube pushes the valve to deform and open the e-liquid filling channel. After filling e-liquid, the valve returns to its original position and closes to prevent e-liquid from flowing out and excessive air contact with e-liquid.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
