Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and more specifically to an atomizing device with switchable oil tanks. Background Technology

[0002] In order to meet the different taste requirements of users, existing atomizers are designed to have multiple flavor tanks, allowing users to switch between different flavors according to their preferences.

[0003] Chinese patent CN202222080585.5 discloses an aerosol generator, including a housing, a first atomizer and a second atomizer disposed inside the housing, and a nozzle structure disposed at the end of the housing. The nozzle structure is rotatably connected to the housing so that the air inlet of the nozzle structure is connected to the air outlet of the first atomizer or the second atomizer. The air inlets of the first atomizer and the second atomizer are connected to the air outlets of a first air inlet channel and a second air inlet channel provided inside the housing, which are independent of each other. In the above patent, the nozzle structure is rotatably connected to the housing, and the nozzle structure is connected to the air outlet of one of the first atomizers or the second atomizer by rotation. Both the first atomizer and the second atomizer have separate atomization channels, which prevents cross-contamination of flavors between the first atomizer and the second atomizer during use.

[0004] The aforementioned patent achieves switching between different atomizers through the rotation of the mouthpiece structure. However, after the mouthpiece structure is switched, the atomizer before switching remains connected to the battery, and the mouthpiece structure and the atomizer before switching cannot achieve a 100% seal. Therefore, the atomizer before switching is highly likely to enter working mode when triggered by a slight airflow to the corresponding microphone. Consequently, the atomizer before switching may be in a powered state, causing it to passively enter working mode. The vapor produced then flows into the vapor produced by the atomizer after switching under the negative pressure of the mouthpiece mechanism, resulting in flavor mixing. Utility Model Content

[0041] Figures 1 to 9 The accompanying drawings are for this utility model.

[0042] This embodiment provides an atomizing device with switchable oil tanks; please refer to [link / reference]. Figures 1 to 4The device includes a housing 10, an oil cup assembly 20 and a circuit board 30 disposed within the housing 10, and a mouthpiece 11 disposed on the upper end of the housing 10. The oil cup assembly 20 has a first airway 21 and a second airway 22 that are isolated from each other. The first airway 21 has a first atomizing core assembly 23, and the second airway 22 has a second atomizing core assembly 24. A switching roller 12 is disposed between the housing 10 and the mouthpiece 11 to allow the mouthpiece 11 to connect with either the first airway 21 or the second airway 22. Rotating the switching roller 12 allows one of the first airway 21 or the second airway 22 to connect with the mouthpiece 11, switching between different oil tanks. Different flavored e-liquids can be filled in the oil tanks, allowing for different flavors to be switched to meet various taste preferences. The switching roller 12 is located near the mouthpiece 11 for easy control during vaping. The first airway 21 and the second airway 22 are isolated from each other to prevent flavor mixing between the airways.

[0043] Preferably, the number of atomizing cores in the first atomizing core group 23 and the second atomizing core group 24 can be one, two, or more. Setting two or more atomizing cores can effectively improve the flavor.

[0044] This also includes a switch 13 for controlling the power supply to the first atomizing coil 23 or the second atomizing coil 24. The switch 13 is positioned near the switching roller 12 so that rotation of the roller 12 opens or closes the switch 13. The power supply to the first atomizing coil 23 or the second atomizing coil 24 is precisely controlled by the switch 13, preventing the first atomizing coil 23 or the second atomizing coil 24 from activating when not in operation. Existing atomizing devices that switch between different atomizing coil operating states generally achieve this by connecting the mouthpiece or switching structure to the desired airflow channel, and then activating the microphone under the influence of airflow. However, this method of controlling the atomizer coil's operation is not precise. The airway cannot be 100% sealed, so in the event of a leak, even a microphone in an inactive airway may be affected by the leaking airflow, causing the atomizer coil in that airway to activate. Consequently, the generated vapor cannot be carried away in time, leading to vapor flowing into the mouthpiece and causing flavor transfer. Furthermore, because the atomizer coil in an inactive airway activates and the vapor cannot be carried away promptly, carbon buildup on the heating coil can occur, affecting the flavor of subsequent use. Therefore, this application uses the switching roller 12 to control the switching switch 13, preventing the atomizer coil assembly in an inactive airway from activating.

[0045] The switch 13 is mounted on the circuit board 30. The circuit board 30 is located on the outside of the oil cup assembly 20, with its upper end close to the switching roller 12. The switch 13 is mounted on the upper end of the circuit board 30, so the rotation of the switching roller 12 can drive the switch 13 to open or close.

[0046] The switching method of the roller 12 turns the switch 13 on or off, which is simple and reliable, and adds to the fun of using the atomizing device.

[0047] The upper end of the housing 10 is provided with a mounting position 100 for mounting the switching roller 12. The switching roller 12 rotates within the mounting position 100. The suction nozzle 11 is connected to the mounting position 100, and a space for the switching roller 12 to rotate is formed between the nozzle and the mounting position 100.

[0048] Please see Figures 2 to 5 The switching roller 12 is provided with several through holes 121. The through holes 121 are used to connect the mouthpiece 11 with the first airway 21 or the second airway 22. When the switching roller 12 rotates, the mouthpiece 11 is connected to the first airway 21 or the second airway 22 through the through holes 121. Specifically, when the switching roller 12 rotates to the point where the through hole 121 is connected to the first airway 21, the first airway 21 is connected to the mouthpiece 11, and the switching switch 13 is turned on to the first atomizing core group 23, allowing the vapor generated by the first atomizing core group 23 to be discharged from the mouthpiece 11; at this time, the second airway 22 is blocked by the switching roller 12, and the switching switch 13 is turned off to the second atomizing core group 24, and the second atomizing core group 24 is in a de-energized state, and vice versa.

[0049] The switching roller 12 has at least two working positions: a first working position and a second working position. When the switching roller 12 is in the first working position, it rotates to the state where the switching switch 13 activates the first atomizing coil 23, allowing the first air passage 21 to connect with the mouthpiece 11 through the through hole 121. In other words, the first atomizing coil 23 is in working condition, and the generated vapor can be discharged from the first air passage 21 through the mouthpiece 11. At this time, the second air passage 22 is blocked by the switching roller 12, and the second atomizing coil 24 is de-energized. When the switching roller 12 is in the second working position, it rotates to the state where the switching switch 13 activates the second atomizing coil 24, allowing the second air passage 22 to connect with the mouthpiece 11 through the through hole 121. Similarly, the second atomizing coil 24 is in working condition, and the generated vapor can be discharged from the second air passage 22 through the mouthpiece 11. At this time, the first air passage 21 is blocked by the switching roller 12, and the first atomizing coil 23 is de-energized.

[0050] Preferably, the switching roller 12 is also provided with a third working position. When the switching roller 12 is in the third working position, the rotation of the switching roller 12 drives the switching switch 13 to switch to the state of disconnecting the first atomizing core group 23 and the second atomizing core group 24, that is, the first atomizing core group 23 and the second atomizing core group 24 are de-energized, and the switching roller 12 isolates the connection between the first air passage 21 and the second air passage 22 and the mouthpiece 11, that is, the switching roller 12 blocks the first air passage 21 and the second air passage 22. Specifically, the third working position is located between the first working position and the second working position. When the switching roller 12 is in the third working position, it can be rotated to the first working position after rotating to the left by a certain angle, and to the second working position after rotating to the right by a certain angle. The third working position is the neutral position of the atomizing device, so that the atomizing device is in a state where it cannot be started, which is convenient for transportation. Moreover, when it is in the third working position, the atomizing device cannot start by itself, which solves the problem that the atomizer is prone to start by itself during the manufacturing, transportation and storage of the atomizing device.

[0051] Preferably, the switch 13 is a toggle switch. Rotation of the switching roller 12 activates the switch 13 to switch between different positions. The switch 13 includes a switching handle 131 that extends to one side of the switching roller 12, allowing rotation of the switching roller 12 to drive the switching handle 131 to different operating positions. Correspondingly, the three operating positions of the switch 13 and the switching roller 12 are matched to each other: a first switch position, a second switch position, and a third switch position. When the switching roller 12 is in the first working position, the switching roller 12 drives the switching switch 13 to the first switch position. At this time, the switching switch 13 controls the first atomizing coil 23 to be in the energized state. When the switching roller 12 is in the second working position, the switching roller 12 drives the switching switch 13 to the second switch position. At this time, the switching switch 13 controls the second atomizing coil 24 to be in the energized state. Similarly, when the switching roller 12 is in the third working position, the switching roller 12 drives the switching switch 13 to the third switch position. At this time, the switching switch 13 controls both the first atomizing coil 23 and the second atomizing coil 24 to be in the de-energized state.

[0052] For details, please refer to Figures 2 to 6A toggle part 122 is provided on the side of the switching roller 12 facing the switching switch 13. The toggle part 122 is used to toggle the switching switch 13 when the switching roller 12 rotates. Specifically, the toggle part 122 rotates and presses the switching handle 131 to switch different positions. There are at least two toggle parts 122, each being a part of the switching roller 12, but protruding outward from one side of the switching roller 12. The two toggle parts 122 are the first toggle part 1221 and the second toggle part 1222. A gap is provided between the first toggle part 1221 and the second toggle part 1222. When the switching handle 131 of the switch 13 is in this gap, the switching roller 12 is in the third working position. A gap is provided on the side of the first toggle part 1221 away from the third working position. When the switching handle 131 of the switch 13 is in this gap, the switching roller 12 is in the first working position. A gap is also provided on the side of the second toggle part 1222 away from the third working position. When the switching handle 131 of the switch 13 is in this gap, the switching roller 12 is in the second working position.

[0053] In this application, the actuating part 122 is disposed on the lower side of the switching roller 12, and the actuating part 122 is a protrusion of the switching roller 12 itself facing the switch 13. In other embodiments, the actuating part 122 may be disposed on the outer side or the upper end surface of the switching roller 12. The placement of the actuating part 122 depends on the installation position of the switch 13. For example, the actuating part 122 may be disposed on the outer periphery of the switching roller 12, in which case the switch 13 is disposed side by side with the switching roller 12; or, the actuating part 122 may be disposed on the upper side of the switching roller 12, in which case the switch 13 is disposed above the switching roller 12.

[0054] Please see Figures 2 to 7 The switching roller 12 is rotatably connected to the housing 10. A rotating shaft is provided on the mounting position 100, and the switching roller 12 is connected to the rotating shaft, allowing the switching roller 12 to rotate between the housing 10 and the switching roller 12. The switching roller 12 is provided with a guide post 123. The housing 10 is provided with a guide rail 101 for the guide post 123 to slide. The guide post 123 slides on the guide rail 101, improving the rotational stability of the switching roller 12 and limiting the rotation angle of the switching roller 12. In this embodiment, the guide post 123 is located on the lower side of the switching roller 12, and the housing 10 is provided with the guide rail 101 near the switching roller 12. The guide post 123 slides along the guide rail 123 to prevent the switching roller 12 from shaking during rotation. In other embodiments, the guide post 123 can also be located on the outer or upper side of the switching roller 12, and the position of the guide rail 101 on the housing 10 changes with the position of the guide post 123.

[0055] Preferably, the guide rail 101 is arc-shaped. The arc of the guide rail 101 corresponds to the rotation angle of the switching roller 12. The two ends of the guide rail 101 are the first and second working positions of the switching roller 12, respectively. That is, when the switching roller 12 rotates to the two ends of the guide rail 101, the atomizing device is in working state; the middle position of the guide rail 101 is the third working position of the switching roller 12, and the atomizing device is in dormant state.

[0056] For preferred options, please refer to [link / reference]. Figures 6 to 7 The inner wall of the guide rail 101 is provided with positioning protrusions 102. The positioning protrusions 102 are arc-shaped, allowing the guide post 123 to slide back and forth over them as it slides within the guide rail 101. The number of positioning protrusions 102 matches the working position of the switching roller 12, therefore there are at least two positioning protrusions 102. The two positioning protrusions 102 divide the guide rail 101 into three areas, corresponding to the first, second, and third working positions of the switching roller 12, respectively. The area between the two positioning protrusions 102 corresponds to the third working position, with the other side of one positioning protrusion 102 being the first working position and the other side of the other positioning protrusion 102 being the second working position. When in the first and second working positions, the through hole 121 of the switching roller 12 is connected to the nozzle 11, that is, the atomizing device is in working state. Therefore, the positioning protrusion 102 can position the switching roller 12 in the first and second working positions to prevent the switching roller 12 from becoming loose in the working state.

[0057] For details, please refer to Figures 6 to 7 To ensure the smooth sliding of the switching roller 12 over the positioning protrusion 102, an elastic strip 103 is provided within the guide rail 101. When the switching roller 12 slides to the positioning protrusion 102, it compresses the elastic strip 103, causing it to deform and allowing the roller to slide smoothly over the protrusion. Furthermore, the switching roller 12 remains stable between the first and second working positions. The positioning protrusion 102 is located on the inner side of the elastic strip 103, which forms the inner wall of the guide rail 101. The guide post 123 slides along the inner side of the elastic strip 103. The middle of the elastic strip 103 is fixedly connected to the housing 10, and gaps are provided between both ends of the elastic strip 103 and the guide rail 101 (or the housing 10), allowing the middle of the elastic strip 103 to be fixed while the two ends are suspended, thus providing elasticity at both ends. Positioning protrusions 102 are located near the two ends of the elastic strip 103, so that the elastic strip 103 has sufficient deformation space when the switching roller 12 presses the positioning protrusions 102. One side of the elastic strip 103 is set to be an arc surface to match the trajectory of the guide post 123 when it rotates.

[0058] The elastic strip 103 is an extension of the housing 10 located on the guide rail 101, and is thus part of the housing 10. This extension is shaped like an arc. A cutout is provided on the opposite side of the extension on the guide rail 101, which serves as the gap between the elastic strip 103 and the guide rail 101. The elastic strip 103 is integrally formed with the housing 10 and can be manufactured through injection molding, stamping, or other processes.

[0059] Please see Figures 2 to 4 To prevent condensate or other liquids from the nozzle 11 from flowing back into the oil cup assembly 20 or leaking out from the gap between the switching roller 12, the housing 10, and the nozzle 11, a first oil-absorbing cotton 14 is provided between the housing 10 and the switching roller 12. The first oil-absorbing cotton 14 is located on the end face of the mounting position 100, so as to absorb condensate or other liquids on the nozzle 11, and at the same time absorb the atomizing liquid flowing out from the oil cup assembly 20.

[0060] Please see Figures 2 to 4 To prevent condensate or other liquids in the suction nozzle 11 from flowing back into the oil cup assembly 20 or leaking out from the gap between the switching roller 12 and the housing 10 and the suction nozzle 11, a second oil-absorbing cotton 15 is provided on the switching roller 12 facing the suction nozzle 11. A groove for housing the second oil-absorbing cotton 15 is provided on the side of the switching roller 12 facing the suction nozzle 11. The second oil-absorbing cotton 15 is embedded in the groove and does not affect the rotation of the switching roller 12.

[0061] Preferably, the nozzle 11 is detachably connected to the housing 10. A slot is provided on the mounting position 100, and a buckle is provided on the nozzle 11. The nozzle 11 is connected to the housing 10 via the buckle and the slot.

[0062] Specifically, the nozzle 11 is provided with two air outlets 111 that are respectively connected to the first air passage 21 and the second air passage 22, which can effectively connect them. The air outlets 111 are connected to the first air passage 21 and the second air passage 22 through the through hole 121 of the switching roller 12. When one air outlet 111 is connected to the first air passage 21 through the through hole 121, the switching roller 12 blocks the other air outlet 111 from connecting to the second air passage 22, and vice versa.

[0063] For preferred options, please refer to [link / reference]. Figures 2 to 48. A first sealing element 16 is provided between the suction nozzle 11 and the switching roller 12. The first sealing element 16 has a connecting hole 161 located at the air outlet 111 of the suction nozzle 11. The lower end face of the first sealing element 16 contacts the switching roller 12, thereby sealing the connection between the switching roller 12 and the connecting hole 161. Specifically, a first sealing ridge 162 is provided on the side of the connecting hole 161 facing the switching roller 12 and around the port of the connecting hole 161, thereby improving the sealing performance between the switching roller 12 and the connecting hole 161. The contour of the upper end face of the first sealing element 16 matches the suction nozzle 11, making the first sealing element 16 more securely fixed and preventing the first sealing element 16 from shifting due to the rotation of the switching roller 12. The first sealing ridge 162 is a portion of the first sealing element 16 that protrudes upwards.

[0064] Please see Figures 2 to 4 A second seal 17 is provided between the switching roller 12 and the mounting position 100. The second seal 17 is located at the air outlet of the first air passage 21 and the second air passage 22, thereby sealing the switching roller 12 with the first air passage 21 and the second air passage 22. Similarly, the second seal 17 has a second sealing ridge 171 on one side near the first air passage 21 and the second air passage 22, improving the sealing performance between the switching roller 12 and the first air passage 21 and the second air passage 22. The second sealing ridge 171 is a portion of the second seal 17 that protrudes upwards.

[0065] Preferably, both the first seal 16 and the second seal 17 are made of silicone.

[0066] In other embodiments, the oil cup assembly 20 is further provided with a third air passage, and a third atomizing core assembly is disposed within the third air passage. The energization or de-energization of the third atomizing core assembly is controlled by a switching switch 13, which is also controlled by the rotation of a switching roller 12. The switching roller 12 is provided with a fourth working position to enable the switching switch 13 to conduct power to the third atomizing core assembly. The third air passage is isolated from both the first air passage 21 and the second air passage 22.

[0067] In other embodiments, the oil cup assembly 20 is further provided with a fourth air passage, and a fourth atomizing core assembly is disposed within the fourth air passage. The energization or de-energization of the fourth atomizing core assembly is controlled by a switching switch 13, which is also controlled by the rotation of a switching roller 12. The switching roller 12 is provided with a fifth working position to enable the switching switch 13 to conduct power to the fourth atomizing core assembly. The fourth air passage is isolated from the first air passage 21, the second air passage 22, and the third air passage.

[0068] In other embodiments, please refer to Figure 9An air inlet 104 is provided at the lower end of the housing 10, and the air inlet 104 communicates with the first air passage 21 and the second air passage 22 provided in the oil cup assembly 20. A switching roller 12 is provided between the air inlet 104 and the first air passage 21 and the second air passage 22, and a switching switch 13 is provided near the switching roller 12 so that the rotation of the switching roller 12 drives the switching switch 13 to open or close. The switching switch 13 controls the first atomizing core group 23 in the first air passage 21 and the second atomizing core group 24 in the second air passage 22 to be energized or de-energized. In this embodiment, the other structures are similar to those in the previous embodiment, except that the position of the switching roller 12 is different.

[0069] Compared with the prior art, the oil cup assembly 20 of this utility model is provided with a first air channel 21 and a second air channel 22 that are isolated from each other. The first air channel 21 is provided with a first atomizing core group 23 and the second air channel 22 is provided with a second atomizing core group 24. The switch 13 controls the first atomizing core group 23 and the second atomizing core group 24 to be energized or de-energized. Moreover, the switch 13 achieves conduction or disconnection by rotating the switching roller 12, so that when one atomizing core group is in the energized state, the other atomizing core group is in the de-energized state, the control is more accurate, the cross-contamination of flavors is eliminated, and the taste experience is effectively improved.
