Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization component and atomization device. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Aerosols can be absorbed by the human body through the respiratory system, providing users with a novel alternative absorption method. Atomizing devices are devices that form aerosols from stored atomizable media through heating or ultrasound. Atomizable media include liquid, gel, paste, or solid aerosol-generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] However, in some atomizing devices, especially those for atomizing high-viscosity aerosol generating matrices, the atomizing chamber has a large volume to accommodate more condensate. But at the same time, this makes it easy for the air entering the atomizing chamber to form eddies, causing the aerosol to collide with the chamber wall more easily and condense to form condensate, which in turn results in a lower aerosol carry-out efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an atomizing component and atomizing device to address the problem of low aerosol carry-out efficiency in atomizing devices.

[0005] An atomizing assembly having an atomizing chamber, the atomizing assembly further comprising:

[0006] A heating element, located on one side of the atomizing chamber, is used to heat the aerosol generating matrix to generate an aerosol; and

[0007] An isolating element is disposed within the atomizing chamber, which divides the atomizing chamber into an atomizing space close to the heating element and a liquid storage space away from the heating element;

[0008] The isolation element and the cavity wall of the atomizing chamber form a reflux channel, which connects the liquid storage space and the atomizing space.

[0009] In one embodiment, the atomizing assembly further includes a conductive element that extends through the atomizing cavity to contact the heating element, and a portion of the conductive element is located within the return channel to guide the flow of the aerosol generation matrix.

[0010] In one embodiment, the isolator has a reflux groove, and part of the reflux groove and the cavity wall of the atomizing chamber together form the reflux channel.

[0011] In one embodiment, the isolation element includes:

[0012] A partition plate separates the atomizing chamber to form the atomizing space and the liquid storage space; and

[0013] At least one drainage portion protrudes from the surface of the isolation plate facing the liquid storage space;

[0014] The return channel extends from the side surface of the flow-in portion away from the isolation plate to the side surface of the isolation plate facing the atomization space.

[0015] In one embodiment, the isolation member includes two drainage portions, which are spaced apart.

[0016] The reflux trough includes a plurality of first reflux sections and a second reflux section. Each first reflux section extends from the flow-in portion to the isolation plate. The second reflux section is formed on the isolation plate and connects all the first reflux sections.

[0017] In one embodiment, the isolator is interference-fitted with the wall of the atomizing chamber.

[0018] In one embodiment, the edge of the isolator and one of the walls of the atomizing chamber are provided with a mounting protrusion, and the edge of the isolator and the other of the walls of the atomizing chamber are provided with a mounting groove, wherein one of the mounting protrusions and one of the mounting grooves are engaged with each other.

[0019] In one embodiment, the heating element has a heating surface for generating aerosol, and the atomizing assembly has an air intake channel communicating with the atomizing space, the air intake channel extending parallel to or intersecting the heating surface of the heating element.

[0020] In one embodiment, the viscosity of the aerosol generating matrix is ​​greater than 200 cp.

[0021] An atomizing device includes the aforementioned atomizing component, and the atomizing device further includes a battery component, the battery component being electrically connected to the conductive element of the atomizing component.

[0022] The aforementioned atomizing component, because the atomizing chamber is divided into upper and lower spaces by an insulating component, allows the airflow entering the atomizing chamber to flow only within the atomizing space. Compared to the airflow flowing throughout the entire atomizing chamber, this effectively reduces the formation of internal eddies, thereby reducing condensation caused by the collision between aerosols and the chamber walls, ultimately improving the aerosol carry-out rate. Furthermore, due to the presence of the return channel, the condensate stored in the liquid storage space can be drawn back to the heating element through capillary action, allowing the condensate to be reused.

[0040] See Figure 1 This application provides an atomizing device 100 for heating an aerosol generating matrix to generate an aerosol for user use. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and beauty purposes. For example, the aerosol generating matrix may be a liquid medicine or an oil. In some specific embodiments, the aerosol generating matrix is ​​a high-viscosity oil. Preferably, the viscosity of the aerosol generating matrix is ​​greater than 200 cp.

[0041] like Figure 2 As shown, the atomizing device 100 includes a housing 20, a mouthpiece 40, an atomizing assembly 60, and a battery assembly 80. The housing 20 is a hollow shell structure with one open end. The mouthpiece 40 is installed at the open end of the housing 20. The atomizing assembly 60 is housed within the housing 20. The battery assembly 80 is installed on one side and electrically connected to the atomizing assembly 60. The atomizing assembly 60 stores an aerosol generating matrix and, under the power of the battery assembly 80, heats and atomizes the aerosol generating matrix to produce an aerosol for the user.

[0042] In the following embodiments, the length direction of the atomizing device 100 is defined as the first direction (i.e., Figure 1 The width direction of the atomizing device 100 is the second direction (i.e., the X direction in the middle). Figure 1 The Y direction in the atomizing device 100 is the height direction of the third direction (i.e., the height direction of the atomizing device 100 is the third direction). Figure 1In the Z direction), the first direction, the second direction, and the third direction intersect each other, and in a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0043] Please combine Figure 2 and Figure 3 As shown, the atomizing assembly 60 includes a main housing 61, a mounting bracket 62, a heating element 63, and a conductive component 64.

[0044] The main housing 61 has a hollow shell structure. Inside the main housing 61, a liquid storage chamber 612, an exhaust channel 614, and a receiving cavity 616 are arranged sequentially in a first direction. The exhaust channel 614 is located between the liquid storage chamber 612 and the receiving cavity 616. The liquid storage chamber 612 is used to store the aerosol generation matrix. The exhaust channel 614 extends in a third direction, and one end of the exhaust channel 614 is connected to the suction nozzle 40 to discharge the aerosol. The receiving cavity 616 is used to receive the battery assembly 80.

[0045] The mounting bracket 62 is fitted to the end of the main housing 61 that is away from the nozzle 40 in the third direction. An atomizing chamber 621 is formed between the mounting bracket 62 and the main housing 61. The atomizing chamber 621 is located on one side of the liquid storage chamber 612 and the exhaust channel 614 in the first direction, and the atomizing chamber 621 is connected to the end of the exhaust channel 614 away from the nozzle 40.

[0046] The heating element 63 is installed at the end of the main housing 61 away from the nozzle 40, and is located between the liquid storage chamber 612 and the atomizing chamber 621 in a third direction. The liquid storage chamber 612 and the atomizing chamber 621 are respectively connected to the opposite side surfaces of the heating element 63 in the first direction. Further, the heating element 63 has a cubic structure and is formed of a high-temperature resistant porous structure such as porous ceramic. The side surface of the heating element 63 facing the atomizing chamber 621 is provided with heating components such as heating wires and heating films, thereby forming a heating surface for heating the aerosol generation matrix to generate aerosols. It is understood that the construction of the heating element 63 is not limited to this and can be configured as needed to meet different atomization requirements.

[0047] There are two conductive elements 64, which are spaced apart along the second direction. One end of each conductive element 64 is connected to the battery assembly 80, and the other end of each conductive element 64 passes through the atomizing cavity 621 along the third direction until it contacts the heating surface of the heating element 63. Therefore, the battery assembly 80 is electrically connected to the heating element 63 through the conductive elements 64. It can be understood that the extension direction of the conductive elements 64 can be set according to the shape of other structures, and is not limited here.

[0048] Thus, the aerosol generating matrix stored in the liquid storage chamber 612 enters the heating element 63. The heating surface of the heating element 63 heats and atomizes the aerosol generating matrix under the action of the electrical energy of the battery assembly 80 to generate aerosol. The aerosol generated by the heating and atomization of the aerosol generating matrix flows out from the atomization chamber 621 and then flows out through the exhaust channel 614 and the nozzle 40 for the user to use.

[0049] like Figure 2 to Figure 5 As shown, in this application, the atomizing assembly 60 further includes an isolating member 65. The isolating member 65 is disposed within the atomizing chamber 621, separating the atomizing chamber 621 into an adjacent atomizing space 6212 and a liquid storage space 6214 in a first direction. The atomizing space 6212 is located on the side of the isolating member 65 closer to the heating element 63, and the liquid storage space 6214 is located on the side of the isolating member 65 away from the heating element 63. A reflux channel 66 is formed between the isolating member 65 and the chamber wall of the atomizing chamber 621, connecting the liquid storage space 6214 and the atomizing space 6212.

[0050] Because the atomizing chamber 621 is divided into upper and lower spaces by the separator 65, the airflow entering the atomizing chamber 621 can flow only within the atomizing space 6212. Compared to the airflow flowing throughout the entire atomizing chamber 621, this effectively reduces the formation of internal eddies, thereby reducing the condensate generated by the collision between the aerosol and the chamber wall of the atomizing chamber 621, ultimately improving the aerosol carry-out rate. Moreover, due to the presence of the return channel 66, the condensate stored in the liquid storage space 6214 can be drawn back to the heating element 63 under capillary action, thus allowing the condensate to be reused.

[0051] In one embodiment, a portion of the conductive element 64 is located within the reflux channel to guide the flow of the aerosol generation matrix, which can enter the heating element 63 along the sidewall of the conductive element 64.

[0052] like Figure 6 to Figure 9 As shown, in some embodiments, the isolator 65 is provided with a reflux groove 652, which extends from the side surface of the isolator 65 facing the liquid storage space 6214 to the side surface facing the atomization space 6212. Part of the reflux groove 652 and the cavity wall of the atomization chamber 621 together form a reflux channel 66. Part of the conductive element 64 may be located in the reflux groove 652 to guide the flow of the aerosol generation matrix.

[0053] Please see Figure 7 to Figure 9 As shown, in some embodiments, the isolation member 65 includes an isolation plate 654 and at least one drainage portion 656.

[0054] The separator 654 is generally flat and is disposed in the atomizing chamber 621. The thickness direction of the separator 654 is parallel to the third direction, thereby dividing the atomizing chamber 621 into an atomizing space 6212 and a liquid storage space 6214. In a preferred embodiment, the height of the atomizing space 6212 in the third direction is 2.75 mm, and the height of the liquid storage space 6214 in the third direction is 1.2 mm. It is understood that the heights of the atomizing space 6212 and the liquid storage space 6214 in the third direction are not limited to these values ​​and can be set as needed to meet different requirements.

[0055] The flow guide 656 protrudes from the surface of the isolation plate 654 facing the liquid storage space 6214. The side of the flow guide 656 away from the isolation plate 654 is located at the end of the liquid storage space 6214 away from the atomization space 6212. The return channel 652 extends from the side of the flow guide 656 away from the isolation plate 654 to the side of the isolation plate 654 facing the atomization space 6212, thereby guiding the condensate from the bottom of the liquid storage space 6214 to the side of the isolation plate 654 facing the atomization space 6212.

[0056] Please continue reading. Figure 8 , Figure 9 As shown, in one specific embodiment, the isolation member 65 includes two drainage portions 656, each drainage portion 656 having a rectangular strip structure, the two drainage portions 656 being spaced apart in a first direction, and each drainage portion 656 extending from one side of the isolation plate 654 to the other side of the isolation plate 654 along a second direction.

[0057] The reflux trough 652 includes a plurality of first reflux sections 6521 and a second reflux section 6523. Each first reflux section 6521 extends from the inlet 656 to the partition plate 654. The second reflux section 6523 is formed on the partition plate 654 and connects all the first reflux sections 6521. Therefore, the condensate at the bottom of the liquid storage chamber 612 flows through the plurality of first reflux sections 6521 to the second reflux section 6523 and then flows along the second reflux section 6523 to the side surface of the partition plate 654 facing the atomization space 6212.

[0058] Specifically, the second return section 6523 extends from one side of the isolation plate 654 to the other side of the isolation plate 654 along the second direction, and the two opposite ends of the second return section 6523 extend along the third direction to the side surface of the isolation plate 654 facing the atomization space 6212. Multiple first return sections 6521 are formed on each flow guide 656, and all the first return sections 6521 on the same flow guide 656 are arranged at intervals along the second direction. One end of each first return section 6521 extends from the end face of the flow guide 656 away from the isolation plate 654 along the third direction toward the isolation plate 654, and the other end of each first return section 6521 extends along the first direction on the isolation plate 654 toward the second return section 6523 until it communicates with the second return section 6523. It is understood that the shape of the return groove 652 is not limited to this and can be configured as needed to meet different return requirements.

[0059] Please refer to it again. Figure 4 , Figure 5 as well as Figure 8 In some embodiments, the isolator 65 is fixed to the mounting bracket 62 by an interference fit with the cavity wall of the atomizing cavity 621. Specifically, one of the edges of the isolator 65 and the cavity wall of the atomizing cavity 621 is provided with a mounting protrusion 6541, and the other of the edges of the isolator 65 and the cavity wall of the atomizing cavity 621 is provided with a mounting groove 6216, wherein one mounting protrusion 6541 and one mounting groove 6216 are correspondingly engaged.

[0060] In a preferred embodiment, the isolation plate 654 of the isolation member 65 has a plurality of spaced mounting protrusions 6541 on both opposite edges in the second direction, and the cavity wall of the atomizing chamber 621 has a plurality of mounting grooves 6216 on both opposite sides in the second direction, with each mounting protrusion 6541 correspondingly engaging with one mounting groove 6216. It is understood that the shape and number of the mounting protrusions 6541 and mounting grooves 6216 are not limited and can be configured as needed to meet different requirements.

[0061] like Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the atomizing component 60 has an air intake channel 624 communicating with the atomizing space 6212. External air enters the atomizing space 6212 through the air intake channel 624, and then carries the aerosol generated by the atomization of the aerosol generation matrix out through the exhaust channel 614.

[0062] Specifically, in some embodiments, the intake channel 624 is formed on the side of the mounting bracket 62 away from the exhaust channel 614 in a first direction, and the extending direction of the intake channel 624 intersects the heating surface of the heating element 63. Therefore, the airflow flowing out of the intake channel 624 flows obliquely or vertically toward the heating surface.

[0063] According to simulation experiments, in the embodiment where the extension direction of the air intake channel 624 intersects with the heating surface of the heating element 63, by setting the isolation member 65, the carry-out rate of small-diameter aerosol particles is increased from 84% to 89.5%, the carry-out rate of large-diameter aerosol particles is increased from 10.6% to 17.0%, and the total carry-out rate of aerosols is increased from 68.3% to 73.3%.

[0064] In some specific embodiments, the intake channel 624 is formed on the side of the mounting bracket 62 away from the exhaust channel 614 in a first direction. The extension direction of the intake channel 624 is parallel to the heating surface of the heating element 63 and extends along the first direction. Therefore, the airflow from the intake channel 624 flows parallel to the heating surface along the first direction. Compared to the intake channel 624 intersecting the heating surface of the heating element 63, the extension direction of the intake channel 624 being parallel to the heating surface of the heating element 63 can further reduce the probability of aerosol colliding with the cavity wall of the atomizing chamber 621, thereby further improving the aerosol carry-out rate.

[0065] According to simulation experiments, in the embodiment where the extension direction of the air intake channel 624 is parallel to the heating surface of the heating element 63, by setting the isolation member 65, the carry-out rate of small-diameter aerosol particles is increased from 90% to 92.2%, the carry-out rate of large-diameter aerosol particles is increased from 6.3% to 6.8%, and the total carry-out rate of aerosols is increased from 73.1% to 74.4%.

[0066] The aforementioned atomizing component 60 and atomizing device 100, through the setting of the isolation member 65, can, on the one hand, divide the atomizing chamber 621 into upper and lower spaces, reduce the formation of eddies in the atomizing chamber 621, and thus effectively reduce the collision between the aerosol and the cavity wall of the atomizing chamber 621, thereby increasing the aerosol carry-out rate; on the other hand, the return groove 652 on the isolation member 65 can be used to draw the condensate in the liquid storage space 6214 back to the heating element 63 through capillary action, so that the condensate can be reused, while preventing excessive condensate in the liquid storage space 6214 from leaking.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
