Technical Field

[0001] This application belongs to the technical field of electronic atomization devices, and particularly relates to an atomization device. Background Art

[0002] The atomization device is formed by combining and connecting an atomization device and a power supply device. The atomization device is used to convert the solution to be atomized stored inside itself into atomized gas, and the power supply device is used to supply power to the atomization device. When a user uses the atomization device to suck, the outside air reaches the mouthpiece through the air inlet opened on the power supply device, inside the power supply device, and inside the atomization device for the user to suck. To meet the user's demand for different air intake amounts during sucking, some atomization devices are provided with an air regulating structure that adjusts different air intake amounts by adjusting the relative connection position between the atomization device and the power supply device.

[0003] However, when using such an atomization device with an air regulating structure for sucking, since the air must pass through the air outlet channel of the power supply device and the connection channel of the atomization device in sequence before finally entering the air inlet channel of the atomization device during the process of entering the atomization device from the power supply device, the flow channel of the air flow is complex; and the existence of the air regulating structure also places many restrictions on the structural design of the connection channel and the air outlet channel. Therefore, when using such an atomization device for sucking, the air flow is very easy to produce a whistling sound, and it is very difficult to reduce the generated whistling sound by conventional methods such as only changing the size of the air flow passage, thereby affecting the user experience. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an atomization device, aiming to solve the technical problem that the air flow of the existing atomization device with an air regulating structure is prone to produce a whistling sound during sucking.

[0037] Please refer to Figure 1-7, an embodiment of the present application provides an atomization device 1, including an atomization device 10 and a power supply device 20. The atomization device 10 is detachably connected to the power supply device 20 to form the atomization device 1. One end of the atomization device 10 is formed with a mouthpiece 110 for the user to suck, and the other end of the atomization device 10 is provided with electrical contacts 120 so that the power supply device 20 can supply power to the atomization device 10. The other end of the atomization device 10 is also provided with a connection structure to facilitate the detachable connection with the power supply device 20. In this embodiment, both the electrical contacts 120 and the connection structure are provided at the bottom of the atomization device 10. Specifically, the connection structure is a magnetic attraction member 130 provided at the bottom of the atomization device 10.

[0038] To enable the power supply device 20 to be detachably connected to the atomization device 10 to form the atomization device 1, the end of the power supply device 20 connected to the atomization device 10 is provided with power supply electrical contacts 220 and a mating connection structure. The power supply electrical contacts 220 are in contact with the electrical contacts 120 of the atomization device 10 so that the power supply device 20 can supply power to the atomization device 10; the mating connection structure matches the connection structure of the atomization device 10 so that the power supply device 20 and the atomization device 10 can form a detachable connection to form the atomization device 1. In this embodiment, the mating connection structure is a magnetic attraction mating member 230 provided on the top of the power supply device 20, and the atomization device 10 and the power supply device 20 are detachably connected by the magnetic attraction force between the magnetic attraction member 130 and the magnetic attraction mating member 230.

[0039] When the user uses the atomization device 1 to suck, the power supply device 20 needs to input a certain amount of intake air to the atomization device 10. Therefore, a main air flow channel 210 is provided inside the power supply device 20, and the outside air can reach the inside of the atomization device 10 through the main air flow channel 210. At the same time, the start of the working state of the atomization device 10 is realized by controlling the power supply of the battery 250 inside the power supply device 20 through the microphone 240 inside the power supply device 20. Therefore, a microphone start air passage (not shown in the figure) is also provided inside the power supply device 20. In order to adjust the intake air volume of the atomization device 10 and ensure that the microphone 240 can normally control the power supply of the battery 250, and considering the connection relationship between the power supply device 20 and the atomization device 10, the end of the power supply device 20 detachably connected to the atomization device 10 is provided with a plurality of first air outlet channels 260 and a second air outlet channel 270. The plurality of first air outlet channels 260 are communicated with the main air flow channel 210 inside the power supply device 20, the second air outlet channel 270 is communicated with the microphone start air passage inside the power supply device, and the inner diameters of the plurality of first air outlet channels 260 are different.

[0040] The bottom of the atomizing device 10 is provided with an air blocking part 140 and an air inlet 150. The air inlet 150 is used to communicate with the first air outlet channel 260 and the second air outlet channel 270. The air blocking part 140 protrudes from the bottom of the atomizing device 10 and is used to block one of the plurality of first air outlet channels 260. When it is necessary to adjust the air intake of the atomizing device 10, only the connection position of the atomizing device 10 relative to the power supply device 20 needs to be changed, so that the inner diameters of the first air outlet channels 260 blocked by the air blocking part 140 are different, and the main air flow channel 210 inside the power supply device 20 will supply different amounts of air intake to the atomizing device 10. It should be noted that no matter what air intake mode the atomizing device 10 is adjusted to, in order to ensure that the microphone 240 can normally control the power supply of the battery 250, the air inlet 150 always remains in communication with the second air outlet channel 270.

[0041] Since there are multiple first air outlet channels 260 and all of them can communicate with the air inlet 150, the relative positional relationship between the first air outlet channels 260 and the air inlet 150 cannot be simply set to be directly opposite to each other. In this embodiment, the bottom of the atomizing device 10 is further provided with a first connection channel 160, and the first connection channel 160 is used to connect the first air outlet channel 260 and the air inlet 150.

[0042] In order to reduce the possible whistling sound generated when the gas enters the first connection channel 160 from the first air outlet channel 260, a micro-perforated plate 300 is provided inside the first connection channel 160. The micro-perforated plate is a sound-absorbing structure that uses the back-and-forth friction of air columns in small holes to consume sound energy. In this embodiment, by providing the micro-perforated plate 300, the whistling sound that may be generated when the air flow passes through can be reduced to the greatest extent by the micro-perforated plate 300.

[0043] Specifically, in this embodiment, for the convenience of installing the micro-perforated plate 300, the micro-perforated plate 300 is fixedly pasted on the inner wall of the first connection channel 160, and the micro-perforated plate 300 is arranged to be directly opposite to the first air outlet channel 260 along the gas flow direction of the first air outlet channel 260. Fixing the micro-perforated plate 300 by pasting is convenient for arranging the micro-perforated plate 300 at the required position in the first connection channel 160, without being restricted by the specific shape of the first connection channel 160. As long as it is ensured that the micro-perforated plate 300 can be accommodated in the first connection channel 160, the micro-perforated plate 300 can be pasted and fixed.

[0044] In this embodiment, a second connection channel 170 is further provided at the bottom of the atomizing device 10. Two ends of the second connection channel 170 are respectively communicated with the second air outlet channel 270 and the air inlet 150. The second connection channel 170 ensures that the microphone activation air passage inside the power supply device 20 can always be communicated with the air inlet 150 through the second air outlet channel 270 and the second connection channel 170, so as to ensure that the microphone 240 can normally control the power supply device 20 to supply power to the atomizing device 10.

[0045] For the atomizing device 1 provided in the embodiment of the present application, the air blocking portion 140 provided at the bottom of the atomizing device 10 can block one of the plurality of first air outlet channels 260. Therefore, blocking the first air outlet channels 260 with different inner diameters by the air blocking portion 140 can realize the power supply device 20 to deliver different air intake amounts to the atomizing device 10, and realize the adjustment of the air intake amount. When the atomizing device 1 has such an air regulating structure, the atomizing device 10 is further provided with a first connection channel 160 for communicating the first air outlet channel 260 of the power supply device 20 with the air inlet 150, and a micro-perforated plate 300 is arranged inside the first connection channel 160. Therefore, when using the atomizing device 1 to suck, during the process that the air flow flows from the first air outlet channel 260 to the first connection channel 160, the micro-perforated plate 300 can reduce or avoid the whistling sound generated by the air flow.

[0046] Please refer to Figure 7 , in an embodiment, the air inlet 150 of the atomizing device 10 is arranged at the central position of the bottom of the atomizing device 10. The atomizing device 10 is only provided with one first connection channel 160, and the first connection channel 160 and the air blocking portion 140 are diagonally arranged at the bottom of the atomizing device 10. The atomizing device 10 is provided with two second connection channels 170, and the two second connection channels 170 are diagonally arranged at the bottom of the atomizing device 10. More specifically, both the first connection channel 160 and the second connection channel 170 are grooves arranged at the bottom of the atomizing device 10.

[0047] Understandably, by arranging the air inlet 150, the first connection channel 160, the air blocking part 140, and the second connection channel 170 at the bottom of the atomizing device 10 according to the above position relationship, only two diagonally arranged first air outlet channels 260 need to be correspondingly arranged at one end of the power supply device 20 detachably connected to the atomizing device 10, and at least one second air outlet channel 270 is arranged, so that after the atomizing device 10 and the power supply device 20 form the atomizing device 1, the air blocking part 140 blocks one of the first air outlet channels 260, and the air inlet 150 is communicated with the other first air outlet channel 260 through the first connection channel 160. By changing the relative position when the atomizing device 10 and the power supply device 20 are detachably connected, the blocking part 140 can block different first air outlet channels 260, so as to realize the adjustment of the air intake of the atomizing device 10; and after the atomizing device 10 and the power supply device 20 are detachably connected to form the atomizing device 1, the air inlet 150 can always be communicated with the second air outlet channel 270 through the second connection channel 170, so as to ensure that the microphone 240 can be normally started.

[0048] Please refer to Figure 6 , in an embodiment, two first air outlet channels 260 and one second air outlet channel 270 are correspondingly arranged at one end of the power supply device 20 detachably connected to the atomizing device 10. The inner diameters of the two first air outlet channels 260 are different, and the two first air outlet channels 260 are diagonally arranged with each other. The second air outlet channel 270 is arranged at the corner position adjacent to one of the first air outlet channels 260. Through the above arrangement, when it is necessary to adjust the air intake of the atomizing device 10 of the atomizing device 1, only the relative position of the atomizing device 10 and the power supply device 20 detachably connected needs to be adjusted so that the first connection channel 160 is respectively communicated with different-sized first air outlet channels 260. Before and after the adjustment process, the second air outlet channel 270 is always communicated with the air inlet 150 through the second connection channel 170, so as not to affect the normal start of the microphone 240, so as to ensure that the microphone 240 can always normally control the power supply of the battery 250 to the atomizing device 10.

[0049] Please refer to Figure 4-5 , in an embodiment, a sound-absorbing cavity 310 is provided between the micro-perforated plate 300 and the inner wall of the first connection channel 160.

[0050] Understandably, by providing the sound-absorbing cavity 310, the micro-perforated plate 300 can have a better sound-absorbing effect, and by providing the sound-absorbing cavity 310, it is also convenient for the micro-perforated plate 300 to control the resonance frequency of the sound absorption peak.

[0051] In some other embodiments, the micro-perforated plate 300 includes a first micro-perforated plate and a second micro-perforated plate arranged in sequence along the direction away from the first air outlet channel. A first sound absorption cavity is provided between the first micro-perforated plate and the second micro-perforated plate, and a second sound absorption cavity is provided between the second micro-perforated plate and the inner wall of the first connection channel.

[0052] Understandably, by providing the double-layer first micro-perforated plate and second micro-perforated plate, and by providing the first sound absorption cavity and the second sound absorption cavity, the micro-perforated plate 300 as a whole has a double-layer resonance sound absorption structure, so that a wider sound absorption frequency band can be obtained, and the sound absorption and noise reduction effect can be better.

[0053] Please refer to Figure 4-5 , in one embodiment, a porous sound absorption material 320 is installed in the sound absorption cavity 310, and the porous sound absorption material 320 is arranged to be closely attached to the surface of the micro-perforated plate 300.

[0054] Understandably, after the porous sound absorption material 320 is installed in the sound absorption cavity 310, the air friction near the micro-holes of the micro-perforated plate 300 is increased, resulting in an increase in resistance. Therefore, the sound absorption coefficient can be improved and the sound absorption frequency band can be broadened. Moreover, the porous sound absorption material 320 is arranged to be closely attached to the surface of the micro-perforated plate 300, so that the sound absorption effect is more obvious.

[0055] Specifically, the porous sound absorption material 320 can be one of porous rock wool materials, foam plastics, linen floss, and sound-absorbing cotton. In this embodiment, the porous sound absorption material 320 is selected as a porous rock wool material.

[0056] Please refer to Figure 8 , in another embodiment, the micro-perforated plate 300 is fixed to one end of the first air outlet channel 260.

[0057] Specifically, the micro-perforated plate 300 is fixed to the end of the first air outlet channel 260 close to the first connection channel 160.

[0058] In this embodiment, the micro-perforated plate 300 is made of nylon material, and the mesh density of the micro-perforated plate 300 is 80 - 300 meshes.

[0059] Through multiple tests by the applicant, the nylon micro-perforated plate 300 with 80 - 300 meshes can achieve good absorption of the whistling sound generated by the airflow, and the nylon mesh material with 80 - 300 meshes is also convenient for processing and selection, and can effectively control the cost.

[0060] Please refer to Figure 8, on the surface of the power supply device 20 near one end of the atomizing device 10, there is an annular protrusion 280. The inner cavity of the annular protrusion 280 is part of the first air outlet channel 260, and the annular protrusion 280 extends into the first connection channel 160. The micro-perforated plate 300 is fixed on the surface of the annular protrusion 280.

[0061] Understandably, by fixing the micro-perforated plate 300 on the annular protrusion 280 extending into the first connection channel 160, the micro-perforated plate 300 can comprehensively and effectively reduce the whistling sound generated by the gas flowing from the first air outlet channel 260 into the first connection channel 160, ensuring the sound absorption effect.

[0062] Please refer to Figure 9 , in another embodiment, the micro-perforated plate 300 is snap-fitted and installed in the first air outlet channel 260.

[0063] Understandably, by fixing the micro-perforated plate 300 in a snap-fitted manner, the processing technology for fixing the micro-perforated plate 300 in the first air outlet channel 260 can be reduced, thus facilitating the installation of the micro-perforated plate 300 and reducing costs; and by directly fixing the micro-perforated plate 300 in the first air outlet channel 260, the air flow must pass through the micro-perforated plate 300, so that the sound absorption effect of the micro-perforated plate 300 is better.

[0064] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
