Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and more specifically, to an electronic cigarette with multiple atomizers. Background Art

[0002] An electronic cigarette generally includes a mouthpiece assembly, an atomizer assembly, and a battery assembly. The battery assembly is equipped with a battery and a control circuit for supplying power to the atomizer assembly. The atomizer assembly includes an atomizer, which is equipped with a liquid storage device and an atomizing core. When powered on, the atomizing core can heat the atomizing liquid stored in the liquid storage device and atomize it into vapor, aerosol, or electronic cigarette smoke for users to inhale.

[0003] A multi-atomizer e-cigarette contains at least two or more atomizers, each of which can contain a different flavor of atomizer liquid. Users can choose to use the atomizers of different flavors alternately. Existing multi-atomizer e-cigarettes switch between different flavor atomizers by rotating the mouthpiece assembly and the atomizer assembly to select one of the atomizers and place it in the working position. When the flavor needs to be changed, the mouthpiece assembly and the atomizer assembly are rotated back to the working position. This mechanical switching method connects the atomizer's air path and circuit to the working air path and circuit.

[0004] In existing rotatable multi-atomizer electronic cigarettes, during the atomizer switching process: some have the atomizer assembly and the mouthpiece assembly fixedly mounted, and when rotating, the atomizer assembly and the mouthpiece assembly rotate simultaneously, causing the airflow channels of each atomizer and the mouthpiece to be opened simultaneously, which can easily lead to insufficient suction or flavor crosstalk between the atomizers; some require first rotating the atomizer assembly to move the atomizer to be used into the working position, then pulling out the mouthpiece assembly and reinstalling it, and during installation, the airflow channel of the mouthpiece assembly needs to be aligned with the smoke channel of the atomizer in the working position; some require first rotating the atomizer assembly to move the atomizer to be used into the working position, and then rotating the mouthpiece assembly to align the airflow channel of the mouthpiece assembly with the smoke channel of the atomizer in the working position. These existing electronic cigarettes either easily cause flavor crosstalk between the atomizers, or do not cause flavor crosstalk but require at least two steps to switch the atomizer to be used, rather than a one-step process. This makes use more cumbersome and inconvenient for users. In addition, some existing rotatable multi-atomizer electronic cigarettes lack direct access to the atomizer assembly. This means the atomizer cannot be directly replaced after the mouthpiece assembly is removed. This results in the need to disassemble more components to replace the atomizer when the atomizer liquid is consumed or when a different flavor atomizer is needed, making it extremely inconvenient to use. Furthermore, in existing rotatable multi-atomizer electronic cigarettes, the atomizer assembly does not lose contact with the battery assembly when the atomizer assembly rotates relative to the battery assembly. This rotational friction can easily cause wear and poor connection at the air path interface, leading to air leaks and reduced smoke output. It can also easily cause wear and scratches at the contact points of the electrodes in the circuit. Furthermore, the electrode columns can easily be damaged by friction during rotation, causing them to swing, bend, or break, leading to poor circuit contact and malfunctions, seriously affecting the user's smoking experience.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The present invention has an electronic cigarette with multiple atomizers, which can heat and atomize the atomized liquid into vapor, aerosol or electronic cigarette smoke for users to inhale. The atomized liquid may include electronic cigarette liquid containing nicotine, a solution containing herbal ingredients or medicinal ingredients, or a solution containing other ingredients. Therefore, the product of the present invention is not limited to use as an electronic cigarette.

[0042] To facilitate the following description, Figure 2 As shown, the mouthpiece assembly of the electronic cigarette is placed vertically upward. The descriptions of "upper, lower, upper part, lower part, bottom, upper end, lower end, bottom end, above, below, left and right" of the various structural parts in the multi-atomizer electronic cigarette of the utility model all refer to the positional relationship of the various structural parts when the mouthpiece assembly of the electronic cigarette is placed vertically upward.

[0043] The present invention is an electronic cigarette with multiple atomizers, wherein multiple atomizers are provided therein, wherein multiple atomizers refer to two or more atomizers. In the following embodiment, the present invention is described based on a scheme in which four atomizers are provided in the electronic cigarette for rotation and switching.

[0044] Example 1:

[0045] like Figure 1 、 Figure 2 As shown, this embodiment of the electronic cigarette with multiple atomizers is composed of a mouthpiece assembly 1, an atomizer barrel 2, and a battery barrel 3 that are coaxially connected in sequence. The mouthpiece assembly 1 can be composed of multiple components combined into one body, or it can be made of multiple materials in one body. The mouthpiece assembly is provided with an air intake channel 10 that runs through it from top to bottom. The atomizer barrel 2 is a hollow cylindrical body with four atomizers 4 installed inside. The atomizer barrel 4 is a rotatable atomizer barrel. The battery barrel 3 is also a cylindrical body. The battery barrel 3 is provided with an air intake channel 30, a battery 5 that provides power to the atomizer 4, and a circuit board (not shown in the figure) that controls the operation of the atomizer.

[0046] In the present invention, the atomizer 4 can use existing technology, and each atomizer 4 is provided with a smoke channel 40 and a heating element and its circuit. Specifically, the atomizer 4 is provided with a liquid storage chamber (not shown), an atomizing core 41, a smoke channel 40, etc. The liquid storage chamber is filled with atomized liquid, and the atomizing core 41 includes a heating element. Both ends of the heating element are connected to a power supply circuit. When the heating element is energized, it can heat the atomized liquid and evaporate it into aerosol or steam-shaped smoke. The bottom of the smoke channel 40 is an inlet and the top is an outlet. The smoke generated by the atomizing core 41 is discharged upward from the outlet and then enters the inhalation channel 10. The user inhales the electronic cigarette smoke into the mouth through the inhalation port at the top of the mouthpiece channel 10.

[0047] like Figure 3 As shown, the nozzle assembly 1 is detachably connected to the upper end of the atomizer barrel 2, and the bottom end of the atomizer barrel 2 is fixedly connected to the battery barrel 3 in the axial direction. In the circumferential direction, the atomizer barrel 2 can rotate relative to the nozzle assembly 1 and the battery barrel 3, that is, when the atomizer barrel 2 rotates, the nozzle assembly 1 and the battery barrel 3 are relatively stationary. With such a connection structure, only one atomizer 4 is in the working position, and the smoke channels 40 of the remaining atomizers 4 are blocked and not connected to the air intake channel 10 of the nozzle assembly and the air intake channel 30 of the battery barrel 3, which can ensure that the atomizer in the working position has sufficient suction and good atomization when in use, and will not cause cross-flavoring of the atomizers. In addition, with such a rotating structure, the atomizer 4 to be used can be switched to the working position by only rotating the atomizer barrel 2. It is extremely simple to use and greatly facilitates the use of the user.

[0048] like Figure 2-Figure 6 、 Figure 15-16 As shown, in this embodiment, there are four atomizer bins 20 and four atomizers 4. The upper end of the atomizer barrel 2 is provided with a completely open opening, and a partition 21 is provided radially inside the atomizer barrel 2. The partition 21 divides the inner cavity of the atomizer barrel 2 into multiple atomizer bins 20, and each atomizer bin 20 is installed with an atomizer 4. The atomizer 4 can be installed and removed through the opening. The structure of the direct opening is set up in this way, so that when the atomized liquid in the atomizer 4 is consumed or when it is necessary to replace the atomizer 4 with a different flavor, there is no need to disassemble more parts. Instead, the atomizer 4 can be taken out by simply pulling out the nozzle assembly 1 and inverting the atomizer barrel 2, and a new atomizer can be directly replaced. This is extremely simple to use and greatly convenient for users.

[0049] like Figure 1-Figure 5As shown, the atomizer barrel 2 is provided with a main shaft 22 at its axis, around which the atomizer barrel 2 can rotate. The bottom of the main shaft 22 is connected to the upper center of the battery barrel 3. By rotating the atomizer barrel 2, one atomizer 4 inside it can be driven into the working position, while the remaining atomizers 4 are simultaneously driven into the standby position. The atomizer 4 in the working position has its smoke passage 40 connected to the air intake passage 10 and the air inlet passage 30, respectively, and its circuit is connected to the circuit of the battery barrel. The atomizer 4 in the standby position has its smoke passage 40 isolated from the air intake passage 10 and the air inlet passage 30, respectively, and its circuit is disconnected from the circuit of the battery barrel.

[0050] like Figure 2 、 Figures 8-10 As shown, the bottom of the nozzle assembly 1 is provided with a blocking member 121 and a sealing protruding ring 122. The blocking member 121 is used to block the outlet of the smoke channel 40 in the standby position, and the sealing protruding ring 122 is used to seal the gap between the inhalation channel 10 and the smoke channel 40. The blocking member 121 can ensure that the smoke channel 40 of the atomizer 4 in the standby position is not connected to the inhalation channel 10, and the sealing protruding ring 122 can ensure that the smoke channel 40 of the atomizer 4 in the working position can be connected to the inhalation channel 10 without air leakage. Such a structure can ensure that the inhalation channel has sufficient suction force and that the smoke sucked out has the flavor of the atomizer liquid in the working position and will not mix with or cross-flavor the flavor of the atomizer liquid in the standby position. The blocking member 121 and the sealing protruding ring 122 of the utility model can be made of a material with sealing properties, such as silicone material or rubber material.

[0051] like Figure 2-Figure 14 As shown, the nozzle assembly 1 includes a nozzle shell 11, a sealing seat 12, and a nozzle bottom cover 13 connected in sequence. The nozzle shell 11 is provided with a vertical nozzle tube 110 at an eccentric position therein to form the suction channel 10. The nozzle bottom cover 13 is upwardly sleeved on the bottom of the nozzle shell 11. The nozzle bottom cover 13 is provided with a bottom cover through-hole 130 corresponding to the outlet of the smoke channel 40. The sealing seat 12 is sleeved between the nozzle shell 11 and the nozzle bottom cover 13. The sealing seat 12 is upwardly provided with a connecting sleeve 120 sleeved on the bottom of the nozzle tube 110. The sealing seat 12 extends downward through the bottom cover through-hole 130 to be provided with a blocking member 121 and a sealing protruding ring 122. A through-hole 123 is provided between the connecting sleeve 120 and the sealing protruding ring 122 to form a part of the suction channel 10. The nozzle holder 12 of the present invention can be made of a sealing material such as silicone or rubber.

[0052] A first connecting member 14 is provided at the bottom center of the nozzle assembly 1, i.e., the bottom center of the nozzle bottom cover 13. A second connecting member 23 is provided at the upper end of the main rotating shaft 22. The first connecting member 14 and the second connecting member 23 are interconnected. In this embodiment, the first connecting member 14 is formed by a first ferromagnet 14, and the second connecting member 23 is formed by a second ferromagnet 23. The first ferromagnet 14 and the second ferromagnet 23 are mutually attracted and connected. Once connected, the nozzle assembly 1 is relatively fixedly connected to the main rotating shaft 22. When the atomizer barrel 2 rotates relative to the main rotating shaft 22, the nozzle assembly 1 remains fixedly connected to the main rotating shaft 22 and does not rotate.

[0053] A circular groove 131 is provided at the center of the bottom of the nozzle assembly 1, i.e., the center of the bottom of the nozzle bottom cover 13. First, the first ferromagnetic body 14 is placed in the circular groove 131. Simultaneously, the upper end of the main shaft 22 also extends into the circular groove 131. The inner wall of the circular groove 131 is provided with a radially protruding strip key 132. The portion where the main shaft 22 extends into the circular groove 131 is provided with a strip groove 221. The strip key 132 is detachably embedded in the strip groove 221. In this way, the nozzle bottom cover 13 is relatively fixed to the main shaft 22. If the main shaft 22 does not move, the nozzle bottom cover 13 also does not move. Furthermore, a groove is provided at the upper end of the main shaft 22 for receiving the second ferromagnetic body 23.

[0054] like Figure 15-17 As shown, a connection hole 31 is provided at the center of the upper portion of the battery canister 3. A screw 32 is provided within the battery canister 3, which passes upward through the connection hole 31 and is connected to the main shaft 22. The screw 32 can be tightened upward against the bottom of the main shaft 22. Simultaneously, the battery canister 3 is connected upward to the atomizer tube 2 by the action of the screw 32. A coil spring 33 is also sleeved around the screw 32 to pull the main shaft 22 and the atomizer tube 3 toward the battery canister 3.

[0055] The upper end of the battery canister 3 is provided with a planar wall 34, on which are located the outlet 301 of the air inlet passage 30 and the electrode column 35. The outer edge of the planar wall 34 is uniformly circumferentially provided with a number of round bumps 36, the same number as the atomizer. In this embodiment, the round bumps 36 are formed by balls fixed at a point. The bottom of the atomizer canister 2 is circumferentially provided with a slide rail 24 for the round bumps 36 to contact and rotate. The slide rail 24 is provided with an equal number of arcuate grooves 25 as the number of round bumps 36. The arcuate grooves 25 are used for positioning. That is, when the round bumps 36 slide into the arcuate grooves 25, they encounter resistance and stop relatively. Sliding the round bumps 36 out of the arcuate grooves 25 requires greater rotational force. When the round protrusion 36 rotates into the arcuate groove 25, one of the atomizers 4 can be rotated and positioned in the working position. At this time, the atomizer tube 2 and the battery tube 3 are relatively fully in contact, and the electrode sheet 42 provided on the bottom of the atomizer 4 can abut against the electrode column 35. At the same time, the inlet of the smoke channel 40 and the outlet of the air inlet channel 30 are closely abutted and connected, so that the atomizer 4 is in the working position. When the atomizer tube 2 continues to rotate, the round protrusion 36 rotates out of the arcuate groove 25 and onto the slide rail 24. The lifting of the bottom of the atomizer tube 2 relative to the battery tube 3 allows the electrode sheet 42 of the atomizer 4 to disengage from the electrode column 35, preventing the electrode column 35 from being damaged by friction during rotation due to swinging, bending or breaking due to friction. This avoids poor circuit contact and malfunction. At the same time, the lifting of the bottom of the atomizer tube 2 relative to the battery tube 3 also causes the inlet of the smoke channel 40 of the atomizer 4 to be disengaged from the outlet of the air inlet channel 30, thereby preventing wear and poor connection caused by friction during rotation due to the air path interface not being disengaged, thereby avoiding air leakage that affects the amount of smoke inhaled.

[0056] Example 2

[0057] Based on the first embodiment, this embodiment makes some changes to the nozzle assembly, and the rest of the changes refer to the first embodiment.

[0058] like Figures 18-24 As shown, the nozzle assembly 1 includes a nozzle shell 11, a sealing seat 12, a nozzle bottom cover 13 and a nozzle shaft 15 connected in sequence. The nozzle bottom cover 13 is upwardly sleeved on the inner bottom of the nozzle shell 11. A connecting tube 133 is provided upward from the bottom center of the nozzle bottom cover 13. The nozzle shaft 15 is upwardly fixed to the inner upper part of the nozzle shell 11 through the connecting tube 133. The nozzle bottom cover 13 can rotate around the nozzle shaft 15. The bottom of the nozzle shaft 15 is provided with a first connecting member 14 as described in Example 1.

[0059] The lower portion of the nozzle bottom cover 13 is detachably connected to the atomizer barrel 2. In this embodiment, a downwardly projecting insertion piece 134 is provided on the lower edge of the nozzle bottom cover 13, and a slot (not shown) is provided on the upper edge of the atomizer barrel 2 for inserting the insertion piece 134. This allows the lower portion of the nozzle bottom cover 13 to be detachably connected to the atomizer barrel 2. When the atomizer barrel 2 rotates, the nozzle bottom cover 13 is driven to rotate along with it. The nozzle housing 11 is connected to the main shaft 22 via the nozzle shaft 15. At this time, if the main shaft 22 does not move, the nozzle housing 11 also does not move.

[0060] The nozzle housing 11 is provided with a vertical nozzle tube 110 at an eccentric position within it, forming the air intake passage 10. A bottom cover through-hole 130 is provided on the nozzle bottom cover 13, corresponding to the outlet of the smoke passage 40. The sealing seat 12 is provided on the nozzle bottom cover 13 and extends downward through the bottom cover through-hole 130 to form a through-hole sleeve 124. Specifically, the through-hole sleeve 124 is inserted through the bottom cover through-hole 130 and has a hollow through-hole at its center. Its upper end opening 125 can abut the bottom end of the nozzle tube 110. The portion of the through-hole sleeve 124 that protrudes downward from the nozzle bottom cover 13 forms a sealing protrusion 122, which abuts around the outlet of the smoke passage 40. When one of the atomizers 4 is in the operating position, the upper end of the through-hole sleeve 124 corresponding to that atomizer 4 abuts the bottom end of the nozzle tube 110.

[0061] In this embodiment, the nozzle assembly 1 is provided with a nozzle shaft 15, allowing the nozzle bottom cover 13 and the sealing seat 12 to rotate about the nozzle shaft 15. Furthermore, the nozzle shaft 15 is fixed to the nozzle housing 11 at its upper portion and fixedly connected to the main shaft 22 at its lower portion via the first connector 14 and the second connector 23. The lower portion of the nozzle bottom cover 13 is connected to the atomizer barrel 2. Therefore, when the atomizer barrel 2 rotates, the nozzle bottom cover 13 is driven to rotate simultaneously, while the nozzle housing 11 remains stationary via the main shaft 22 and the battery barrel 3.
