A cigarette cartridge structure and its assembly method that prevents the outer shell from getting too hot.

Abstract

This invention discloses a cartridge structure and its assembly method that prevents the outer shell from getting too hot to handle. The inner cavity of the outer shell is divided into a first placement cavity, a second storage cavity, and a third atomization cavity. The second storage cavity is used to store e-liquid. The third atomization cavity connects the mouthpiece and the atomization channel. The first placement cavity is used to place the atomizing device. At least one pair of heat-insulating fins are provided between the heating element of the atomizing device and the outer shell. The atomization channel is a labyrinthine channel that extends along the heat-insulating fins. The heat-insulating fins are located outside the atomization chamber, preventing the heat from the atomization chamber from being directly dissipated to the outer shell. Furthermore, cold air enters from the bottom air inlet of the atomizing device in the first placement cavity and rises, first contacting the outer shell to reduce its temperature, and then flowing through the heating element to the third atomization cavity. This allows for rapid heat exchange and diversion of the heat transferred from the heating element to the cartridge shell, quickly reducing the temperature of the cartridge shell, preventing burns, and improving the user experience.

Description

[0002] Social progress and technological development have spurred rapid advancements in industrial production technology and residents' living standards. Consequently, the demands on production equipment technology and daily necessities have also increased. Many technological products are developing towards miniaturization and thinness; mobile phones are becoming thinner, televisions are becoming thinner, and e-cigarettes are also becoming thinner, giving rise to ultra-thin e-cigarette cartridges. However, e-cigarettes require heating devices to atomize e-liquid during use. While pursuing a thin and light design, features such as heat protection are also necessary. In existing ultra-thin e-cigarette cartridges, the cartridge shell easily heats up during continuous inhalation, causing burns to the consumer's hands and severely impacting the user experience. Moreover, the temperature increases with prolonged use.

[0003] Furthermore, in existing technology, after continuous use causes the cartridge shell temperature to become too high, it takes a relatively long time for it to cool down naturally to a normal temperature, which hinders consumers from using it again. Summary of the Invention

[0055] like Figures 1-8 As shown, in order to provide a cartridge structure and its assembly method that can prevent the outer shell from getting hot, the present invention is designed as follows: First, a structure for a cartridge structure that can prevent the outer shell from getting hot is conceived. The basic structure is a thin and light outer shell 1. The inner cavity of the outer shell 1 is divided into a first placement cavity 11, a second storage cavity 12 and a third atomizing cavity 13. The first placement cavity 11 is located in the lower section of the inner cavity of the outer shell 1. The atomizing device can be placed in the first placement cavity 11 to refill the e-liquid and atomize it into smoke, which is convenient for consumers to vape.

[0056] The second storage chamber 12 is located in the upper part of the inner cavity of the outer shell 1. The second storage chamber 12 can store e-liquid, thereby maintaining the continuous atomization of e-liquid during the use of the e-liquid cartridge so that consumers can continue to vape for a period of time.

[0057] The third mist chamber 13 is disposed in the center of the second storage chamber 123. One end of the third mist chamber 13 is connected to the mouthpiece at the top of the outer shell 1, and the other end of the third mist chamber 13 is connected to the atomization channel of the atomizing device. The atomizing device heats and atomizes the e-liquid, and the resulting smoke is transported to the third mist chamber 13 through the atomization channel. Consumers can then inhale through the mouthpiece.

[0058] An air inlet 16 is provided at the center of the bottom surface of the atomizing device, and an air outlet 31 and an oil inlet 32 ​​are provided at the top of the atomizing device. An atomizing chamber 33 with an open bottom is provided in the middle of the atomizing device. The atomizing chamber 33 is connected to the second storage chamber 12 through the oil inlet 32. The e-liquid stored in the second storage chamber 12 can flow into the atomizing chamber 33 through the oil inlet 32 ​​and be heated and atomized by the heating element inside the atomizing chamber 33. The air inlet 16 is connected to the third mist chamber 13 through the atomizing channel and the air outlet 31. At least one pair of heat insulation fins are provided between the atomizing chamber 33 and the outer shell 1. This design allows the atomization channel to bend and extend along the heat insulation fins, forming a labyrinthine channel. Cold air enters the atomization channel through the air inlet 16 and flows along the channel. The heat insulation fins block the heat from being directly dissipated to the outer shell of the atomization chamber. Furthermore, the cold air enters from the bottom air inlet of the atomization device in the first mounting cavity and rises, first contacting the outer shell to reduce its temperature, and then flowing through the heating element to the third atomization chamber. This design enables rapid heat exchange and diversion of the heat transferred from the heating element to the cartridge shell, quickly reducing the temperature of the cartridge shell, preventing burns, and improving the user experience.

[0059] In actual operation, the specific structure of the atomizing device is first composed of an atomizing bracket 3, an oil-separating pad 4, a heating element 5, and an atomizing base 6. The air outlet 31 is located in the middle of the top surface of the atomizing bracket 3. An atomizing chamber 33 with an open bottom is set in the middle of the atomizing bracket 3. The oil-separating pad 4 and the heating element 5 are both limited and installed in the inner cavity of the atomizing chamber 33. Oil inlets 32 are respectively set on both sides of the air outlet 31 on the top surface of the atomizing bracket 3. The two ends of the atomizing chamber extend upward and connect to the two oil inlets 32. The e-liquid stored in the second storage chamber 12 can flow into the atomizing chamber 33 simultaneously through the two oil inlets 32 and soak into the heating element 5.

[0060] Furthermore, the atomizing base 6 is positioned below the atomizing bracket 3, allowing the atomizing bracket 3 to be positioned and installed in the first mounting cavity 11 of the outer shell via the atomizing base 6. Firstly, a pair of first heat-insulating fins 61 are symmetrically arranged on the upper part of the atomizing base 6. Each first heat-insulating fin 61 extends obliquely from the inside out and upward. The pair of first heat-insulating fins 61 are positioned between the outer sides of the atomizing chamber 5 and the outer shell 1, so that the heat in the space on both sides of the atomizing chamber 5 does not directly contact the outer shell 1.

[0061] The air inlet 16 is located in the middle of the bottom surface of the atomizing base 6. The roots of the pair of first heat insulation fins 61 are separated from each other. The atomizing channel extends from the air inlet 16 along the hollow inner cavity of the atomizing base 6 to the bottom of the atomizing chamber 33, then extends upward along the space on both sides of the atomizing chamber 33, and then converges and connects to the air outlet along the top surface of the atomizing chamber 33 to the middle.

[0062] The specific structure of the atomizing bracket 3 is as follows:

[0063] The main structure of the atomizing bracket 3 is a horizontal main support plate 34. A lower support foot 35 is set at each of the two lower support feet 35. The atomizing chamber 33 is set in the middle of the space between the two lower support feet 35. The upper sections of a pair of first heat insulation fins 61 extend to the top of the atomizing base 6 and extend upward along the edge of the space between the two lower support feet 35. The structure is simple and compact, and the shape of the pair of first heat insulation fins 61 can be adapted to the shape of the space between the two lower support feet 35.

[0064] Furthermore, a pair of second heat-insulating fins 62 are symmetrically arranged in the inner cavity of the atomizing base 6 below the first heat-insulating fin 61. Each second heat-insulating fin 62 extends obliquely from the inside out and upward, so that the upper part of each second heat-insulating fin 62 also extends to the top of the atomizing base 6. The pair of second heat-insulating fins 62 further shield the outside of the pair of first heat-insulating fins 61, further preventing the heat emitted from the bottom opening of the atomizing chamber from contacting the outer shell. The roots of the pair of second heat-insulating fins 62 are fixedly connected together by a connecting part, so that the pair of second heat-insulating fins 62 have an integral V-shaped structure. There is a through channel between the bottom end of the pair of first heat-insulating fins 61 and the upper surface of the pair of second heat-insulating fins 62, and there is also a through channel between the bottom end of the pair of second heat-insulating fins 62 and the side wall 64 of the atomizing base 6. The atomizing channel extends tortuously along the lower and upper surfaces of the pair of second heat-insulating fins 62, so that the atomizing channel forms a labyrinthine channel.

[0065] Specifically, the atomizing channel extends vertically upward from the air inlet to the root of a pair of second heat insulation fins, then extends outward and upward along the lower surface of the pair of second heat insulation fins to the top of the pair of second heat insulation fins, then extends inward and downward along the upper surface of the pair of second heat insulation fins to the upper surface of the connection part of the pair of second heat insulation fins, continues to extend vertically upward to the bottom surface of the atomizing chamber, then extends obliquely upward along the space between the pair of first heat insulation fins and the atomizing chamber, and finally extends along the upper surface of the atomizing chamber and converges to the air outlet.

[0066] A first limiting plate 63 protruding outward is provided around the perimeter of the opening of the atomizing base 6. The atomizing base 6 is fixedly mounted in the first placement cavity 11 by interference fit with the inner surface of the outer shell 1 through the first limiting plate 63. A second limiting plate 65 protruding outward is provided on the lower outer surface of the atomizing base 6. The atomizing base can cooperate with the pressure cap structure of the outer shell 1 through the second limiting plate 65, thereby limiting and fixing the pressure cap structure of the outer shell.

[0067] A guide pin structure 38 is also provided at the lower end of the lower support foot 35 of the atomizing bracket 3. The atomizing bracket 3 is inserted into the inner cavity of the atomizing base 6 through the pin structure 38 to further limit and fix the atomizing bracket.

[0068] Furthermore, the atomizing device is equipped with an electrode holder 7 and a pair of electrodes 8, forming an electrical assembly; a transverse limiting groove 66 is provided in the lower section of the atomizing base 6, and the electrode holder 7 is limited and positioned in the transverse limiting groove 66. The air inlet 16 is vertically inserted through the middle of the electrode holder 7, and the pair of electrodes 8 are symmetrically arranged on the electrode holder 7 at positions on both sides of the air inlet 16; the tops of the pair of electrodes 7 pass through the atomizing base 6 and press against the bottom surface of the heating element 5, providing electrical energy to the heating element 5.

[0069] Furthermore, the lower end of each electrode 8 is a square column structure, the transverse limiting groove 66 is a stepped groove structure, and the electrode seat 7 is also a stepped structure, which can prevent radial rotation during the assembly process.

[0070] Furthermore, a silicone sealing element 2 is installed above the atomizing bracket 3. The specific structure of the sealing element 2 is as follows:

[0071] The upper section of the seal 2 is sealed and blocked between the main support plate 34 of the atomizing bracket 3 and the inner surface of the outer shell 1 by the sealing plate 21; the middle part of the upper section of the seal 2 is limited and blocked between the air outlet 31 of the atomizing bracket 3 and the second storage chamber 12 by the upper sealing spacer 20 and the limiting step at the lower end of the second storage chamber 12. The upper section of the seal 2 is also provided with through holes corresponding to each oil inlet 32 ​​to facilitate the flow of e-liquid; the lower section of the seal 2 is provided with lower sealing spacers 22 at both ends, and the seal 2 is sealed and connected to the outer side of the middle part of the atomizing bracket 3 by the lower sealing spacers 22 to ensure sealing performance.

[0072] The upper end of the atomizing base is pressed tightly against the lower support foot of the atomizing bracket, thereby limiting the atomizing bracket to be placed in the first mounting cavity through the atomizing base and the sealing element, which is stable and reliable.

[0073] Finally, the heating element 5 is a rectangular ceramic heating element, and the oil separator 4 is a rectangular frame structure made of silicone. The oil separator 4 is sealed between the heating element 5 and the inner top surface of the atomizing chamber 33, which is safe and reliable; this is a conventional setting method in the prior art.

[0074] This invention also relates to a method for assembling a cartridge structure that prevents the outer shell from getting too hot, for assembling the aforementioned cartridge structure that prevents the outer shell from getting too hot, specifically performed according to the following steps:

[0077] S03, fill the oil separator into the atomizing chamber;

[0078] S04, stack the ceramic heating element in the atomizing chamber and press the oil separator pad tightly; the technical solution of this application does not involve the detailed structural features of the ceramic heating element and the oil separator pad. The specific structure of the ceramic heating element and the oil separator pad can adopt the conventional structure of the ceramic heating element and the oil separator pad in the prior art. The filling and pressing of the ceramic heating element and the oil separator pad can be carried out in accordance with conventional operations.

[0091] This invention relates to a cartridge structure and assembly method that prevents the outer shell from getting too hot.

The third atomization cavity connects the mouthpiece and the atomization channel. The first placement cavity is used to place the atomizing device. At least one pair of heat-insulating fins are provided between the heating element of the atomizing device and the outer shell. The atomization channel is a labyrinthine channel that extends along the heat-insulating fins. The heat-insulating fins are located outside the atomization chamber, preventing the heat from the atomization chamber from being directly dissipated to the outer shell. Furthermore, cold air enters from the bottom air inlet of the atomizing device in the first placement cavity and rises, first contacting the outer shell to reduce its temperature, and then flowing through the heating element to the third atomization cavity. This allows for rapid heat exchange and diversion of the heat transferred from the heating element to the cartridge shell, quickly reducing the temperature of the cartridge shell, preventing burns, and improving the user experience.
