Aerosol generating device

Abstract

The present invention relates to an aerosol generating device, comprising a pluggable aerosol generating mechanism and a power control mechanism. A sealing assembly is provided between the aerosol generating mechanism and the power control mechanism, and the sealing assembly seals the gap between the aerosol generating mechanism and the power control mechanism bracket. By providing the sealing assembly between the aerosol generating mechanism and the power control mechanism, the aerosol generating device seals the gap between the aerosol generating mechanism and the power control mechanism. This prevents airflow from entering the aerosol generating mechanism through the gap between the aerosol generating mechanism and the power control mechanism, and allows airflow to enter the aerosol generating mechanism only through an air inlet channel preset in the power control mechanism. This ensures good airtightness and precisely controls the amount of air entering the aerosol generating mechanism, thereby ensuring that the aerosol generating device can generate a stable amount of aerosol and a stable inhalation experience, without causing empty inhalation or excessive inhalation resistance.

Description

Technical Field

[0001] The present invention relates to the technical field of cigarette substitutes, and in particular to an aerosol generating device. Background Art

[0002] An aerosol generating device is an electronic product that imitates cigarettes, with similar smoke, taste and feel to cigarettes. Due to its cool appearance, multiple optional flavors and convenience of inhalation, aerosol generating devices have been rapidly promoted and used.

[0003] Currently, common e-liquid aerosol generating devices on the market include an aerosol generating mechanism and a power control mechanism. The aerosol generating mechanism is the aerosol-generating portion of the aerosol generating device, while the power control mechanism is the control device of the aerosol generating device. The power control mechanism provides power to the aerosol generating mechanism and controls its activation and deactivation. Powering on the aerosol generating mechanism heats the e-liquid in the aerosol generating mechanism to form an aerosol, transforming various flavors of e-liquid into aerosol for the user to inhale. Specifically, inhaling at the mouthpiece of the aerosol generating mechanism triggers the power control mechanism to supply power to the aerosol generating mechanism, causing it to heat and atomize the e-liquid.

[0004] For aerosol generating devices with replaceable aerosol generating mechanisms, the aerosol generating mechanism and the power control mechanism are removable and replaceable, and air intake is also achieved through a preset air intake hole in the power control mechanism, or through a preset air intake channel at the interface between the aerosol generating mechanism and the power control mechanism. However, due to process errors, there may be errors within the tolerance range between different components, which may lead to inconsistent airtightness between the aerosol generating mechanism and the power control mechanism. Even for aerosol generating devices with bottom air intake, poor airtightness between the aerosol generating mechanism and the power control mechanism may result in additional air intake gaps in addition to the preset air intake channel, resulting in the air intake flow rate not being controlled by the preset control, thereby causing the user to have a large air inhalation or inhalation resistance during use.

[0029] See also Figure 1 , is a schematic structural diagram of an aerosol generating device in one embodiment.

[0030] See also Figures 1 to 6 An aerosol generating device includes an aerosol generating mechanism 10 and a power control mechanism 20, which are pluggable and compatible. The aerosol generating mechanism 10 is the aerosol generating device, and the power control mechanism 20 is the control center of the aerosol generating device. The power control mechanism 20 provides electrical energy for the aerosol generating mechanism 10 to generate aerosol. During use, inhalation from the aerosol generating mechanism 10 triggers the power control mechanism 20 to energize and heat the e-liquid to generate aerosol, forming an aerosol for the user to inhale. A sealing assembly 30 is provided between the aerosol generating mechanism 10 and the power control mechanism 20 to seal the gap between the aerosol generating mechanism 10 and the bracket of the power control mechanism 20.

[0031] The aerosol generating device provides a sealing assembly 30 between the aerosol generating mechanism 10 and the power control mechanism 20 to seal the gap between the aerosol generating mechanism 10 and the power control mechanism 20. This prevents the airflow from entering the aerosol generating mechanism 10 through the gap between the aerosol generating mechanism 10 and the power control mechanism 20, and allows the airflow to enter the aerosol generating mechanism 10 only through the air inlet channel preset by the power control mechanism 20. This ensures good airtightness and precisely controls the amount of air entering the aerosol generating mechanism 10, thereby ensuring that the aerosol generating device can generate a stable amount of aerosol and a stable inhalation taste without the occurrence of empty inhalation or excessive inhalation resistance.

[0032] For details, please refer to Figure 2 、 Figure 3 and Figure 5 The aerosol generating mechanism 10 includes a housing 12 and a base 14. The housing 12 includes a nozzle end and a base 14 end. The base 14 is disposed at the base 14 end of the housing 12, i.e., the nozzle and base 14 are disposed at both ends of the housing 12. The power control mechanism 20 includes a plug end adjacent to the aerosol generating mechanism 10, and the base 14 end is plugged into the plug end. The sealing assembly 30 is disposed between the base 14 end and the plug end to seal the gap between the base 14 end and the plug end. In other words, when the aerosol generating mechanism 10 and the power control mechanism 20 are plugged together, the sealing assembly 30 can be disposed at either the plugged end or the mating sidewalls. It is sufficient to seal the gap between the aerosol generating mechanism 10 and the power control mechanism 20.

[0033] For more details, see Figure 4 、 Figure 6 The sealing assembly 30 includes a sealing protrusion 32 and a sealing ring 34. The power control mechanism 20 is provided with a first air inlet 22, a first air outlet 24 is provided at the plug-in end, and a second air inlet 1422 is provided at the end of the base body 14, the second air inlet 1422 being connected to the first air outlet 24. The sealing protrusion 32 is disposed around the periphery of the first air outlet 24, and the sealing ring 34 is disposed around the periphery of the second air inlet 1422, with the sealing protrusion 32 and the sealing ring 34 mating. Specifically, the sealing assembly 30 is disposed at the interface between the aerosol generating mechanism 10 and the power control mechanism 20. After the aerosol generating mechanism 10 and the power control mechanism 20 are plugged in and installed, the sealing protrusion 32 abuts against the sealing ring 34, sealing the gap around the second air inlet 1422. Airflow is prevented from entering through the gap between the aerosol generating mechanism 10 and the power control mechanism 20, maintaining good airtightness and facilitating a stable inhalation experience and a stable aerosol volume.

[0034] In another embodiment, the sealing assembly 30 includes a sealing protrusion 32 and a sealing ring 34. The power control mechanism 20 is provided with a first air inlet 22, a first air outlet 24 is provided at the plug-in end, and a second air inlet 1422 is provided at the end of the base body 14, the second air inlet 1422 being in communication with the first air outlet 24. The sealing protrusion 32 is disposed around the outer periphery of the second air inlet 1422, and the sealing ring 34 is disposed around the outer periphery of the first air outlet 24, with the sealing protrusion 32 abutting against the sealing ring 34. Specifically, the sealing assembly 30 is disposed at the interface between the aerosol generating mechanism 10 and the power control mechanism 20. After the aerosol generating mechanism 10 and the power control mechanism 20 are plugged in and installed, the sealing protrusion 32 abuts against the sealing ring 34, sealing the gap around the second air inlet 1422. This prevents air from entering through the gap between the aerosol generating mechanism 10 and the power control mechanism 20, thereby maintaining good airtightness and facilitating a stable inhalation experience and a stable aerosol volume.

[0035] Of course, in another embodiment, the sealing component 30 can also be arranged on the outer wall of the base 14 end of the aerosol generating mechanism 10 and the inner wall of the plug-in end of the power control mechanism 20. By sealing the gap between the two walls, the airflow can be prevented from entering the second air inlet 1422 through the plug-in gap between the aerosol generating mechanism 10 and the power control mechanism 20, thereby maintaining good air tightness, which is conducive to maintaining a stable inhalation taste and a stable aerosol amount.

[0036] Preferably, at least one of the sealing protrusion 32 and the sealing ring 34 is made of soft silicone. Since the soft silicone has a certain degree of deformation, it can achieve a better sealing effect and better airtightness under the action of a certain force.

[0037] Here, the certain force may be a magnetic force or a squeezing force.

[0038] See also Figure 2 、 Figure 3 and Figure 5 In this embodiment, the shell 12 includes an atomizing shell 122, a nozzle cover 124 and a bottom shell 126, the base 14 includes a base 142 and a sealing seat 144, and the aerosol generating mechanism 10 also includes an atomizing tube 128 and an atomizing core 129; the atomizing shell 122 includes a nozzle end and a base 14 end, the nozzle cover 124 is arranged at the nozzle end of the atomizing shell 122, the sealing seat 144, the base 142 and the bottom shell 126 are sequentially arranged at the base 14 end of the atomizing shell 122, the atomizing tube 128 is arranged in the atomizing shell 122, and the two ends of the atomizing tube 128 are respectively connected to the nozzle end and the sealing seat 144, dividing the interior of the atomizing shell 122 into an oil storage chamber 1222 and an atomizing chamber 1224, and the atomizing core 129 is arranged in the atomizing chamber 1224 and communicates with the oil storage chamber 1222.

[0039] Among them, the sealing seat 144 can be made of a soft material, and its edge is in contact with the inner wall of the atomizer shell 122, sealing the gap between the base 142 and the inner wall of the atomizer shell 122 to prevent the oil in the oil storage chamber 122 from leaking out. The oil storage chamber 1222 can store oil or oil storage cotton. The advantage of the oil storage cotton is that the oil is absorbed by the oil storage cotton and usually does not leak out of the oil storage chamber 1222. The nozzle end of the atomizer shell 122 is provided with an oil filling hole. After the atomizer tube 128, the atomizer core 129, the sealing seat 144, the base 142, the bottom shell 126 and the atomizer shell 122 are assembled, oil can be poured into the oil storage chamber 1222 through the oil filling hole. After the oil filling is completed, the nozzle cover 124 is covered on the atomizer shell 122 to complete the assembly. Preferably, the mouthpiece shell and the atomizer shell 122 cannot be disassembled after assembly, that is, the aerosol generating mechanism 10 is a disposable mechanism, and a new aerosol generating mechanism 10 and the power control mechanism 20 can be replaced after the e-liquid is inhaled.

[0040] Of course, a sealing ring 34 can be provided on the outer wall of the nozzle end of the atomizer shell 122. After the nozzle cover 124 and the atomizer shell 122 are assembled, the sealing ring 34 can seal the gap between the nozzle cover 124 and the atomizer shell 122 to prevent the smoke oil from leaking from the oil filling hole.

[0041] The atomizer tube 128 includes a mounting tube 1282, a separator tube 1284, and a docking tube 1286. One end of the mounting tube 1282 is fixed to the sealing seat 144, and the other end is provided with a mounting groove 1288. The atomizer core 129 is fixed in the mounting groove 1288 and communicates with the oil storage chamber 1222. The wall of the mounting tube 1282 is provided with an oil guide hole 1289. The provision of the mounting groove 1288 facilitates the assembly of the atomizer core 129. The atomizer core 129 can be directly held and slid along the mounting groove 1288 into the mounting tube 1282. The exposed portion of the atomizer core 129 can directly contact and drain the smoke liquid. The oil guide hole 1289 on the wall of the mounting tube 1282 can also drain the smoke liquid from the oil storage chamber 1222, which helps to maintain the uniformity and sufficiency of the oil. The docking tube 1286 is provided on the atomizing shell 122 and may be integrally formed with the atomizing shell 122 for plugging and fixing the separating tube 1284; both ends of the separating tube 1284 are respectively plugged into the mounting tube 1282 and the docking tube 1286; thus, the interior of the atomizing shell 122 is divided into an oil storage chamber 1222 and an atomizing chamber 1224, that is, the outside and the inside of the separating tube 1284 are respectively the oil storage chamber 1222 and the atomizing chamber 1224, the atomizing core 129 is located in the atomizing chamber 1224, and the airflow entering from the second air inlet 1422 flows through the atomizing chamber 1224 to the nozzle.

[0042] See also Figure 5In this embodiment, the base 142 is provided with a mounting position, and the first magnetic member 1424 is provided in the mounting position of the base 142. In order to facilitate uniform force, it is preferably symmetrically provided with at least two first magnetic members 1424. Correspondingly, the plug-in end of the power control mechanism 20 is provided with a second magnetic member 26, and the number matches the first magnetic member 1424. After the first magnetic member 1424 and the second magnetic member 26 are magnetically adapted, the aerosol generating mechanism 10 and the power control mechanism 20 will be tightly attracted due to the magnetic force. The sealing protrusion 32 and / or the sealing ring 34 can produce a certain deformation under the action of the magnetic force, which has a better sealing effect and better airtightness; of course, the stability of the cooperation between the aerosol generating mechanism 10 and the power control mechanism 20 can also be guaranteed.

[0043] In another embodiment, a buckle or buckle hole is provided at the end of the base 14 of the aerosol generating mechanism 10, and a buckle hole or buckle is provided at the plug-in end of the power control mechanism 20. After the buckle and the buckle hole are adapted and clamped, the aerosol generating mechanism 10 and the power control mechanism 20 will generate a certain extrusion force on the sealing protrusion 32 and / or the sealing ring 34. The sealing protrusion 32 and / or the sealing ring 34 can be deformed to a certain extent under the action of the magnetic force, thereby having a better sealing effect and better airtightness; of course, the stability of the cooperation between the aerosol generating mechanism 10 and the power control mechanism 20 can also be guaranteed.

[0044] In this embodiment, a sealing protrusion 32 is disposed around the outer periphery of the first air outlet 24, which protrudes from the plug-in end and is inserted into the second air inlet 1422. A liquid reservoir 28 is formed between the outer periphery of the first air outlet 24 and the sealing protrusion 32. After the aerosol generating mechanism 10 has been used for a period of time, a certain amount of condensate will be generated in the atomization chamber 1224. A portion of the condensate will be absorbed by the atomization core 129 and then atomized. The remaining portion that is not absorbed by the atomization core 129 in time will flow into the liquid reservoir 28 for storage. This prevents the condensate from flowing through the first air outlet 24 to the power control mechanism 20, where it could corrode the power control mechanism 20 and affect its performance and service life.

[0045] The atomizer core 129 includes a heating element and an oil guide element. The heating element is bent into a spring shape, and the oil guide element is wrapped around the outside of the heating element. A hand-held portion can also be provided on the side of the oil guide element to adapt to the mounting slot 1288.

[0046] In this embodiment, an air outlet channel 29 is provided at the plug end, the first air outlet hole 24 is connected to the air outlet channel 29, and the power control mechanism 20 is triggered to start by sensing air pressure through the first air outlet hole 24. That is, the gap in the power control mechanism 20 can serve as an airflow channel for air intake, eliminating the need to reserve a separate space for an airflow channel. Simply providing the first air inlet hole 22 and the first air outlet at the air intake and outlet can limit the airflow rate. Furthermore, the air outlet channel 29 is provided at the plug end, and an airway for triggering the pneumatic switch of the power control mechanism 20 can be preset within the air outlet channel 29. Inhaling at the suction nozzle can trigger the pneumatic switch. The air outlet channel 29 can clearly regulate the airflow channel within the power control mechanism 20 at the plug end, ensuring precise airflow.

[0047] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
