Description

Technical Field

[0001] This utility model relates to the field of dual-heating-coil e-cigarette cartridge technology, specifically to an e-cigarette cartridge with short-circuit-proof dual-heating-coil. Background Technology

[0002] E-cigarette cartridges, also known as e-liquid cartridges, are components in e-cigarettes used to store e-liquid and atomize it to produce vapor. As the power of finished e-cigarette cartridges on the market continues to increase, the resistance of the heating wire in the cartridge continues to decrease, and the temperature that the heating wire can withstand continues to increase. Even if the heating wire pins are insulated, it is still impossible to avoid the short circuit caused by the wire burning through during the heating process, which can lead to malfunctions of the cartridge, such as dual-electrode cartridges becoming single-electrode cartridges or even the cartridges being completely scrapped.

[0003] In the comparative case, patent publication number CN218126976U discloses an atomizing device for a dual-heating-element cartridge assembly. This atomizing device includes a dual-heating-element cartridge assembly and a body assembly; the dual-heating-element cartridge assembly and the body assembly are detachably connected; a liquid storage chamber is formed inside the cartridge assembly shell; a first power supply circuit and a second power supply circuit are connected in parallel for the dual-heating-element cartridge assembly; one electrode of the first heating element is electrically connected to the first atomizer electrode of the first power supply circuit via a first pin, and the other electrode of the first heating element is electrically connected to the second atomizer electrode of the second power supply circuit via a second pin; one electrode of the second heating element is electrically connected to the first atomizer electrode via a third pin, and the other electrode of the second heating element is electrically connected to the second atomizer electrode via a fourth pin; the first and second atomizer electrodes protrude from the cartridge assembly shell to achieve electrical connection with the body assembly. This utility model uses two heating elements, resulting in a large vapor production volume and a good user experience.

[0004] However, during the implementation of the relevant technology, the following problems were found in the atomization device of the above-mentioned dual-heating-element cartridge assembly. Compared with the case using a dual-heating-element structure, namely a first heating element and a second heating element, the amount of smoke generated when the user inhales is significantly increased compared with a single heating element structure, greatly improving the user's experience. As the power of existing finished cartridges continues to increase, the resistance of the cartridge heating wire continues to decrease, and the temperature of the heating wire continues to increase. Even if the heating wire pins are wrapped with wire insulation, it is impossible to avoid the phenomenon of short circuit due to burnt wire insulation during the heating process, which leads to defective cartridges, the problem of dual-element becoming single-element, or even the cartridge being completely scrapped.

[0005] Therefore, it is necessary to design and modify the cartridges to effectively prevent the finished cartridges from continuously increasing in power, continuously decreasing in resistance of the heating wire, and continuously increasing in temperature. Even if the heating wire pins are wrapped with wire insulation, it is still impossible to avoid the short circuit caused by the wire insulation burning through during the heating process, which would lead to malfunctions of the cartridges, such as dual-electrode cartridges becoming single-electrode cartridges or even the cartridges being scrapped. Utility Model Content

This solves the problem that as the power of finished cartridges continues to increase, the resistance of the heating wires in cartridges continues to decrease, and the temperature of the heating wires continues to rise. Even if the heating wire leads are wrapped with wire insulation, it is still impossible to avoid the short circuit caused by the wire insulation burning through during the heating process, which leads to defective cartridges, dual-firing becoming single-firing, or even the cartridge being completely scrapped.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cigarette cartridge with short-circuit resistant dual heating wires, comprising;

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, the present invention provides a cigarette cartridge with a short-circuit-proof dual heating wire, comprising:

[0026] Oil tank shell 1, oil filling plug 2 is inserted into the right side of oil tank shell 1, oil tank sealing silicone 3 is inserted into the bottom of the inner cavity of oil tank shell 1, oil tank base 4 is inserted into the bottom of oil tank sealing silicone 3, magnets 5 are installed on both sides of the bottom of oil tank base 4, and assembly mechanism 6 is inserted into the bottom of oil tank base 4.

[0027] The assembly 6 includes an atomizing core cover 61, a heating wire 62, a bracket 63, insulating silicone 64, and a heating wire fixing seat 65. The atomizing core cover 61 is inserted into the bottom of the oil tank base 4. The heating wire 62 is installed in the inner cavity of the atomizing core cover 61. The bracket 63 is installed at the bottom of the atomizing core cover 61 and at the position corresponding to the heating wire 62. The insulating silicone 64 is movably installed at the bottom of the bracket 63. The heating wire fixing seat 65 is installed at the bottom of the insulating silicone 64. An insulating mechanism 7 is provided at the top of the inner cavity of the atomizing core cover 61 and on the surface of the heating wire 62.

[0028] refer to Figure 4 The insulation mechanism 7 includes an outer cotton 71, an inner cotton 72, and a bracket O-ring 73. The outer cotton 71 is provided at the top of the inner cavity of the atomizing core cover 61 and on the surface of the heating wire 62. The inner cotton 72 is provided at the top of the heating wire 62 and at the bottom of the outer cotton 71. The bracket O-ring 73 is inserted into the bottom of the bracket 63. The bottom of the heating wire fixing seat 65 is provided with a connecting mechanism 8.

[0029] As a technical optimization of this utility model, by setting the insulation mechanism 7, the outer cotton 71, the inner cotton 72 and the bracket O-ring 73 can be preferentially assembled inside the atomizing core outer cover 61 corresponding to the heating wire 62, thereby protecting the positive and negative poles of the heating wire 62 and avoiding cross-short circuit of the heating wire.

[0030] refer to Figure 5 The connecting mechanism 8 includes an oil-absorbing cotton 81, an atomizing core base 82, an electrode 83, and an oil-proof O-ring 84. The bottom of the heating wire fixing seat 65 is provided with an oil-absorbing cotton 81, the bottom of the atomizing core cover 61 is provided with an atomizing core base 82, the left and right sides of the inner cavity of the atomizing core base 82 are provided with electrodes 83, and an oil-proof O-ring 84 is inserted into the center of the bottom of the atomizing core base 82.

[0031] As a technical optimization of this utility model, by setting the connecting mechanism 8, oil-absorbing cotton 81, electrode 83 and oil-proof O-ring 84 can be preferentially assembled inside the atomizing core base 82, so that oil leakage will not occur inside the atomizing core base 82, and the sealing effect of oil leakage inside the atomizing core base 82 is not ideal.

[0032] refer to Figure 1 The atomizer core base 82 has air inlets 9 at both the front and back ends, and the air inlets 9 are distributed at an angle.

[0033] As a technical optimization of this utility model, the setting of the air inlet 9 can assist the air circulation between the atomizing core base 82 and the atomizing core cover 61, and avoid the atomizing core base 82 being solid, which would prevent air circulation.

[0034] refer to Figure 6 An O-ring 10 is provided at the bottom of the oil tank base 4 and at the top of the atomizer core cover 61. The O-ring 10 is used in conjunction with the atomizer core cover 61.

[0035] As a technical optimization of this utility model, the O-ring 10 can assist the atomizing core cover 61 in its operation and also serve as a seal, preventing leakage caused by gaps at the connection between the oil tank base 4 and the atomizing core cover 61.

[0036] refer to Figure 6 There are two magnets 5 and three electrodes 83. Magnets 5 are used in conjunction with the oil tank shell 1, and electrodes 83 are used in conjunction with the atomizing core base 82.

[0037] As a technical optimization of this utility model, the setting of magnet 5 and electrode 83 can ensure normal operation and avoid the individual impact of magnet 5 and electrode 83 on work efficiency.

[0038] The working principle and usage process of this utility model are as follows: During use, an oil filling plug 2 is installed on the right side of the oil tank outer shell 1. Then, the oil tank sealing silicone 3 is inserted into the interior of the oil tank outer shell 1. Next, the entire structure is aligned with the oil tank base 4 and inserted for fixation. Before connecting the oil tank base 4 to the oil tank outer shell 1, a magnet 5 is first installed. Then, the atomizing core cover 61 is inserted into the bottom of the oil tank base 4 for installation. The atomizing core cover 61 is first fitted with insulating silicone 64 to prevent the positive electrode of the heating wire 62 from contacting the bracket 63. After routing the wires, the heating wire fixing seat 65 is installed to fix the wiring positions of the three heating wires 62. Before installing the atomizer core cover 61 with the oil tank base 4, first install the heating wire 62 in the bracket 63 with the inner cotton 71, outer cotton 72, and atomizer core cover 61. After the above installation and docking are completed, the heating wire 62 does not need to be fixed with glue. Finally, align the above-assembled accessories with the atomizer core base 82 and plug them in to fix them. Before plugging the heating wire fixing seat 65 into the atomizer core base 82, first install the oil-absorbing cotton 81, electrode 83, and oil-proof O-ring 84 before assembly. The above-mentioned addition of a heating wire fixing seat 65 at the insulating silicone 64 position solves the short circuit caused by the crossover of the three heating wire 62 pins and the burnt wire insulation.

[0039] In summary: This e-cigarette cartridge with short-circuit-proof dual heating coils works by using the following components: e-liquid tank shell 1, e-liquid plug 2, e-liquid tank sealing silicone 3, e-liquid tank base 4, magnet 5, assembly mechanism 6, atomizer coil cover 61, heating coil 62, bracket 63, insulating silicone 64, heating coil fixing seat 65, and insulation mechanism 7. During assembly, with the heating coil 62 held in the bracket 63 and the atomizer coil cover 61 installed, the insulating silicone 64 is then installed. The insulating silicone 64 prevents the positive terminal of the heating coil 62 from contacting the bracket 63. Then, the cartridge is properly positioned. The heating wire fixing bracket 65 fixes the wiring position of the three heating wires 62, thereby achieving protective insulation of the heating wires 62 and avoiding short circuits or burning of the plastic due to high temperature. This solves the problem that with the continuous increase of the power of existing finished e-cigarette cartridges, the resistance of the heating wires in the cartridges is continuously decreasing, and the temperature of the heating wires is continuously increasing. Even if the heating wire leads are wrapped with wire insulation, it is still impossible to avoid the short circuit caused by burning through the wire insulation during the heating process, which leads to malfunctions of the e-cigarette cartridges, such as dual-electrode conversion to single-electrode conversion or even the complete scrapping of the e-cigarette cartridge.
