[0040] An embodiment of the present application provides an atomizing device. Through a reasonable airway design, an annular air flow is formed in the air outlet passage to isolate the gas flowing out of the atomizing passage from the inner wall of the air outlet passage, thereby avoiding the phenomenon of condensation on the inner wall of the air outlet passage.

[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] As Figures 1 - 5 shown, the atomizing device in the present application includes an oil cup 1 and an atomizing assembly 2. The oil cup 1 (for storing the liquid to be atomized, such as e - liquid; see the following discussion for details) and the atomizing assembly 2 (a structure for atomizing the liquid to be atomized, see the following discussion for details) cooperate to form a gas diversion channel. The gas diversion channel includes a diversion channel 5, an atomizing channel 6, and an air outlet channel 7. The inlet ends of the diversion channel 5 and the atomizing channel 6 are both in communication with the outside of the atomizing device, that is, the inlet ends of the diversion channel 5 and the atomizing channel 6 are both in communication with the external environment. The outlet end of the diversion channel 5 and the outlet end of the atomizing channel 6 are both in communication with the air outlet channel 7. Among them, the outlet end of the diversion channel 5 is arranged around the outer periphery of the outlet end of the atomizing channel 6 to use the gas flowing out of the diversion channel 5 to isolate the aerosol flowing out of the atomizing channel 6 from the inner wall of the air outlet channel 7.

[0043] During the use of the above - mentioned atomizing device, a part of the gas entering the atomizing device enters the diversion channel 5, and under the guiding action of the diversion channel 5, it enters the air outlet channel 7 in the form of an annular air flow (the annular air flow refers to an air flow whose radial cross - section is annular). Another part enters the atomizing channel 6 to participate in the formation of the aerosol and enters the air outlet channel 7. Since the outlet end of the diversion channel 5 is arranged around the outlet end of the atomizing channel 6, the aerosol flowing out of the atomizing channel 6 is located inside the above - mentioned annular air flow. That is, the annular air flow flowing out of the diversion channel 5 can isolate the aerosol from the inner wall of the air outlet channel 7. In this way, it can effectively avoid the contact between the aerosol and the inner wall of the air outlet channel 7, and further avoid the condensation phenomenon on the inner wall of the air outlet channel 7.

[0044] It can be understood that as mentioned above, the gas diversion channel includes a diversion channel 5, an atomization channel 6, and an air outlet channel 7. However, in specific implementations, the composition of the gas diversion channel is not limited thereto. For example, in some embodiments, an intake channel 4 may also be provided to introduce gas from the external environment into the diversion channel 5 and the atomization channel 6. Based on this, the present application does not limit the manner in which the intake end of the diversion channel 5 and the intake end of the atomization channel 6 communicate with the outside of the atomization device. For example: the intake end of the diversion channel 5 and the intake end of the atomization channel 6 can be directly communicated with the outside of the atomization device; or, the intake end of the diversion channel 5 and the intake end of the atomization channel 6 can be indirectly communicated with the outside of the atomization device through one or more intake channels 4.

[0045] In some embodiments, the flow rate of the gas entering the diversion channel 5 is Q1, and the flow rate of the gas entering the atomization channel 6 is Q2, and Q1 < Q2. It should be understood that taking an electronic cigarette as an example of the atomization device, during its use, when the suction force and suction resistance are constant, the suction volume (the total volume of air inhaled by the user through the electronic cigarette device during one electronic cigarette suction process) will not fluctuate within a large range. Based on this, if a large amount of gas enters the diversion channel 5 during the user's suction process, it will cause a decrease in the amount of gas entering the atomization channel 6, thereby directly affecting the generation amount of the aerosol. Based on this, this embodiment limits Q1 < Q2 to ensure that the flow rate of the gas entering the atomization channel 6 is sufficient, avoiding the influence on the generation amount of the aerosol in the atomization channel 6 due to some gas entering the diversion channel 5, and thus ensuring the use effect of the atomization device. Exemplarily, in some embodiments, the ratio of the flow rate of the gas entering the diversion channel 5 from the intake channel 4 to the flow rate of the gas entering the atomization channel 6 from the intake channel 4 is greater than 0 and less than 3 / 7; that is, 0 < Q1 / Q2 < 3 / 7. Specifically, the ratio of the flow rate of the gas entering the diversion channel 5 from the intake channel 4 to the flow rate of the gas entering the atomization channel 6 from the intake channel 4 can be 2 / 8 or 1 / 9, etc.

[0046] In some embodiments, along the gas flow direction, the cross-sectional area of the diversion channel 5 gradually decreases. According to Bernoulli's principle (under ideal conditions, at any cross-section of the same flow tube, the sum of the kinetic energy, potential energy, and pressure potential energy of the unit volume of fluid is a constant), when the cross-sectional area of the diversion channel 5 decreases, the gas flow rate will increase to compensate for the potential energy reduced due to the narrowing of the flow channel. And the increase in the gas flow rate is more conducive to the formation of an annular air flow of the gas flowing out of the diversion channel 5, thereby isolating the gas flowing out of the atomization channel 6 from the inner wall of the air outlet channel 7 to avoid the occurrence of condensation on the inner wall of the air outlet channel 7.

[0047] As mentioned above, the air outlet end of the diversion channel 5 is arranged around the outer periphery of the air outlet end of the atomization channel 6. It should be noted that the above-mentioned surrounding arrangement can be achieved by providing the diversion channel 5 with a plurality of local air outlets, and the plurality of local air outlets are arranged around the outer periphery of the atomization channel 6; or it can be achieved by providing an annular local air outlet (that is, the end face of the air outlet end is annular, specifically, it can be circular, elliptical or polygonal annular, etc.), and the annular local air outlet is arranged around the atomization channel 6. For the convenience of understanding, below, taking the diversion channel 5 having an annular local air outlet arranged around the atomization channel 6 as an example, the gas diversion channel in the present application will be described in more detail.

[0048] As Figure 2 and Figure 5 shown, the oil cup 1 in the present application includes a housing 101, and an air pipe 102 and a separator 103 arranged inside the housing 101. Among them, the housing 101 has a suction nozzle end 1011 and an open end 1012 that are opposite to each other in the longitudinal direction. The separator 103 divides the internal space of the housing 101 into a liquid storage chamber 10 and an installation chamber 12 for installing the atomization assembly 2 in the longitudinal direction, and the liquid storage chamber 10 and the installation chamber 12 are communicated through a liquid outlet 9. The liquid to be atomized stored in the liquid storage chamber 10 is guided to the atomization assembly 2 by using the liquid outlet 9 to ensure the normal use of the atomization device.

[0049] It should be noted that any two or all of the housing 101, the air pipe 102 and the separator 103 can be independent different structures, or they can also be different parts in an integrally formed structure. In this regard, the present application does not make specific limitations. However, when all of the housing 101, the air pipe 102 and the separator 103 are different parts in an integrally formed structure, a liquid injection hole communicating with the liquid storage chamber 10 also needs to be provided to facilitate the injection of the liquid to be atomized into the liquid storage chamber 10.

[0050] It should also be noted that on the basis that the housing 101 and the separator 103 are two independent different structures, the liquid outlet 9 can be formed by the cooperation of the housing 101 and the separator 103. For example, it can be a liquid guiding gap reserved between the housing 101 and the separator 103 (as Figure 2 shown); or the liquid outlet 9 can also be a through-hole structure on the housing 101 and the separator 103. In specific implementation, it can be adaptively designed according to needs.

[0051] Continuing as Figure 2 and Figure 5As shown, the installation cavity 12 has a communication port 1201 communicating with the ventilation pipe 102. One end of the ventilation pipe 102 communicates with the suction nozzle end 1011, and the other end communicates with the communication port 1201 to form an air outlet channel 7. The atomization assembly 2 is disposed in the installation cavity 12 and is provided with at least a part of an atomization channel 6. The air outlet ends of the atomization channel 6 and the shunt channel 5 are both located at one end of the atomization assembly 2 facing the communication port 1201, so that the gas flowing out of the atomization channel 6 and the gas flowing out of the shunt channel 5 can enter the air outlet channel 7.

[0052] Furthermore, as Figure 5 shown, an air outlet groove 2011 is provided on one end face of the atomization assembly 2 facing the communication port 1201. The notch of the air outlet groove 2011 forms the air outlet end where the shunt channel 5 communicates with the communication port 1201, and the notch of the air outlet groove 2011 is annular and surrounds the air outlet end of the atomization channel 6. That is to say, the above-mentioned air outlet groove 2011 is the local air outlet of the shunt channel 5.

[0053] Even further, as Figure 5 shown, an oil absorption cotton 8 for absorbing condensate is provided at the bottom of the air outlet groove 2011. It should be understood that compared with the gas flowing out of the atomization channel 6, the temperature of the gas flowing out of the shunt channel 5 is lower. Based on this, when the two meet, there is a certain probability of generating condensate. Based on this, the oil absorption cotton 8 provided at the bottom of the air outlet groove 2011 in this embodiment can prevent the condensate from accumulating at the position of the air outlet groove 2011 and affecting the flow of the gas in the shunt channel 5.

[0054] It should be noted that the above-mentioned air outlet groove 2011 is only one implementation manner for forming the annular air outlet part of the shunt channel 5, but the present application is not limited thereto. For example: an annular protrusion that can extend into the air outlet channel 7 can also be provided on one end face of the atomization assembly 2 facing the communication port 1201. After the annular protrusion extends into the air outlet channel 7, there is a gap between the annular protrusion and the inner wall of the air outlet channel 7. The annular protrusion cooperates with the inner wall of the through hole forming the air outlet channel 7 in the oil cup 1 to form the annular outlet part of the shunt channel 5.

[0055] In addition, on the basis that the air outlet groove 2011 is provided as the air outlet part of the diversion channel 5, in the axial direction of the air outlet channel 7, the projections of the air outlet groove 2011 and the atomization channel 6 both fall inside the projection of the air outlet channel 7 (it should be noted that the "inside" mentioned here includes the case where the outer edge of the projection of the air outlet groove 2011 coincides with the edge of the projection of the air outlet channel 7). In this way, the interference of the air outlet channel 7 on the air flow flowing out of the air outlet groove 2011 can be reduced, so that the air flow flowing out of the air outlet groove 2011 maintains an annular shape. At the same time, it can also prevent the air outlet channel 7 from interfering with the air flow flowing out of the atomization channel 6, so as to ensure that the air flow flowing out of the atomization channel 6 is located inside the annular air flow flowing out of the air outlet groove 2011. Specifically, in some exemplary embodiments, such as Figures 2 - 4 shown, the air outlet groove 2011 is an annular groove with a circular ring-shaped notch. The radial cross-sections of the atomization channel 6 and the air outlet channel 7 (this radial cross-section is the cross-section perpendicular to the corresponding axis direction, the same below) are both circular and extend along a longitudinal straight line. The air outlet ends of the air outlet groove 2011 and the atomization channel 6 both face the air outlet channel 7. The diameter of the radial cross-section of the air outlet channel 7 is greater than the diameter of the radial cross-section of the air outlet groove 2011 which is greater than the diameter of the radial cross-section of the atomization channel 6, so that in the axial direction of the air outlet channel 7, the projections of the air outlet groove 2011 and the atomization channel 6 both fall inside the projection of the air outlet channel 7.

[0056] Furthermore, in some embodiments, the air outlet groove 2011, the atomization channel 6 and the air outlet channel 7 are coaxially arranged. In this way, the distribution of the isolation air flow (that is, the annular air flow flowing out of the diversion channel 5, the same below) between the aerosol and the inner wall of the air outlet channel 7 is more uniform, and the isolation effect of the isolation air flow is better, avoiding that the gas flowing out of the diversion channel 5 cannot be fully utilized due to uneven air flow distribution, and making part of the inner wall of the air outlet channel 7 contact the aerosol.

[0057] In addition, in some embodiments, at least part of the diversion channel 5 is defined between the atomization assembly 2 and the inner wall of the installation cavity 12 (that is, part of the diversion channel 5 is formed by the atomization assembly 2 cooperating with the inner wall of the installation cavity 12), and the atomization assembly 2 is provided with at least part of the atomization channel 6. Exemplarily:

[0058] such as Figure 5 shown, the atomization assembly 2 includes a base body 201 and a heating element 202. Part of the diversion channel 5 is defined between the base body 201 and the inner wall of the installation cavity 12. The base body 201 is provided with a through hole penetrating along its axis to form the atomization channel 6. The air outlet groove 2011 is opened on one end face of the base body 201 facing the communication port 1201 and is arranged around the outer periphery of the through hole; the heating element 202 is arranged inside the atomization channel 6 and serves as the heat source for atomization to promote atomization so as to form an aerosol in the atomization channel 6.

[0059] It can be understood that on the basis that the atomization component 2 includes the base body 201 and the heating element 202, the liquid in the liquid storage cavity 10 needs to be specifically guided to the position of the heating element 202 to achieve atomization. Based on this, according to the different materials of the base body 201, in the specific implementation process, the structure of the base body 201 also needs to be adjusted adaptively. Exemplarily, when the base body 201 is made of a dense material (such as plastic, silica gel, dense ceramic, etc.), a liquid guiding channel (not shown in the figure) communicating with the heating element 202 in liquid needs to be provided on the base body 201, so that the liquid in the liquid storage cavity 10 can flow to the position of the heating element 202 under the guidance of the liquid guiding channel. When the base body 201 is made of a porous material (such as porous ceramic), since the porous material itself has a certain liquid guiding ability, redundant liquid guiding channels can be not provided. During the atomization process, the liquid in the liquid storage cavity 10 can flow to the position of the heating element 202 under the liquid guiding action of the base body 201 itself.

[0060] In addition, regarding the heating element 202, it refers to a heating element that can dissipate heat to atomize the liquid in the atomization device. Exemplarily, it can be a metal heating element formed by spiraling or weaving, such as a columnar spiral heating wire; of course, the structural form of the heating element 202 is not limited to the columnar structure, and can also be a flat structure, such as a sheet-shaped heating sheet. In addition, in terms of materials, the heating element 202 can be made of a single porous conductive material, such as porous conductive ceramic, porous metal body, or can also include a composite structure made of a porous material and a conductive material, such as a composite body formed by porous ceramic or porous glass and an etched metal sheet or metal coating.

[0061] Furthermore, on the basis that the atomization component 2 includes the base body 201 and the shunt channel 5 includes an air outlet groove 2011 provided on the base body 201, as Figure 3 shown, the shunt channel 5 further includes an air inlet groove 2012 opened on the outer wall of the base body 201, and the air inlet groove 2012 extends to one end face of the base body 201 facing the communication port 1201 and communicates with the air outlet groove 2011; after the base body 201 is assembled into the installation cavity 12 of the oil cup 1, the air inlet groove 2012 and the inner wall of the installation cavity 12 cooperate to form the air inlet part of the shunt channel 5. This setting method, since the structure for forming the shunt channel 5 on the base body 201 is exposed on the surface of the base body 201, can effectively reduce the processing difficulty of the shunt channel 5, thereby being beneficial to improving production efficiency and reducing production costs.

[0062] In addition, as Figure 2As shown, the atomizing device further includes a base 3, which is disposed at the open end 1012 of the oil cup 1 and is located at the other end of the base body 201 away from the communication port 1201. An air inlet channel 4 communicating with the atomizing channel 6 and the shunt channel 5 is provided on the base 3. When the atomizing device is in use, external gas enters the installation cavity 12 through the air inlet channel 4, and under the action of the pressure difference, it flows into the shunt channel 5 and the atomizing channel 6.

[0063] It should be noted that: regarding the number of the air inlet channels 4, in specific implementation, it can be adaptively designed according to needs. Exemplarily, the number of the air inlet channels 4 can be one as shown in Figure 5 shown. In this way, using one air inlet channel 4 to supply gas to both the shunt channel 5 and the atomizing channel 6 simultaneously is beneficial to the processing of the air inlet channel 4 while ensuring smooth ventilation, and can avoid affecting the structural strength of structures such as the base 3 due to the setting of multiple air inlet channels 4. In addition, multiple air inlet channels 4 can also be provided to communicate with the shunt channel 5 and the atomizing channel 6 respectively. In this way, it is more convenient to control the ratio of the gas entering the shunt channel 5 and the gas entering the atomizing channel 6.

[0064] Furthermore, as shown in Figure 5 shown, a receiving groove 2013 communicating with the air inlet groove 2012 is further provided at the end of the base body 201 away from the communication port 1201. A protruding portion 301 is provided on the side of the base 3 facing the base body 201, and the air inlet channel 4 penetrates through the protruding portion 301. In this way, by raising the height of the outlet of the air inlet channel 4 in the installation cavity 12, it is possible to prevent the condensate or leakage liquid in the atomizing channel 6 from flowing to the outside through the air inlet channel 4.

[0065] In addition, on the basis of the above, in order to ensure that external gas can enter the atomizing channel 6, an air inlet gap 11 communicating with the atomizing channel 6 is formed between the protruding portion 301 and the side wall of the receiving groove 2013; during the use of the atomizing device, part of the gas flowing out of the air inlet channel 4 enters the atomizing channel 6 through the air inlet gap 11 to ensure the normal use of the atomizing device.

[0066] Furthermore, the flow area of the air inlet gap 11 is larger than the flow area of the air inlet groove 2012, so that the flow rate of the gas flowing out of the air inlet channel 4 and entering the atomizing channel 6 through the air inlet gap 11 is greater than the flow rate of the gas flowing out of the air inlet channel 4 and flowing into the shunt channel 5.
