Technical Field

[0001] The present application relates to the field of atomization, and particularly to an atomization device. Background Art

[0002] Inside an atomization device, the liquid particles for forming aerosol usually need to be guided to a target area through an air outlet channel under the action of air flow. For example, in an electronic cigarette product, the e-liquid particles generated by an atomization core need to be transported to the user's mouth through the air outlet channel under the action of air flow.

[0003] However, in the related art, due to the single flow direction of the air flow, the mixing effect of the air flow and the liquid particles for forming aerosol is poor, which will affect the use effect of the atomization device. Summary of the Utility Model

[0005] To achieve the above object, the present application provides the following technical solutions:

[0008] Preferably, the swirl channel has an annular portion disposed around the air outlet end of the atomization channel, one end of the first outlet portion is communicated with the annular portion, and the other end is communicated with the air outlet end of the atomization channel;

[0009] And, a plurality of the first outlet portions are provided, and the plurality of first outlet portions are evenly distributed around the air outlet end of the atomization channel.

[0010] Preferably, the swirl channel further has a second outlet portion extending along a second direction and communicating with the air outlet channel, and the second direction is the axial direction of the air outlet channel, so as to isolate the aerosol flowing out of the atomization channel from the inner wall of the air outlet channel by using a part of the gas flowing out of the swirl channel.

[0011] Preferably, the atomization channel includes an air inlet section and an air outlet section, and the air outlet section is coaxially arranged with the air outlet channel.

[0012] Preferably, the flow rate of the gas entering the swirl channel from the air inlet channel is Q1, and the flow rate of the gas entering the atomization channel from the air inlet channel is Q2, and Q1 < Q2.

[0013] Preferably, 0 < Q1 / Q2 < 3 / 7.

[0014] Preferably, along the gas flow direction, the cross-sectional area of the swirl channel gradually decreases.

[0015] Preferably, the atomization assembly includes:

[0016] A base body, with a through hole arranged along its axis to form the air outlet section;

The air inlet channel is arranged on the base, and the air outlet channel is arranged on the oil cup, and the atomization cavity communicates with the air inlet channel and the air outlet channel;

[0019] In the assembled state, the atomization assembly is arranged in the atomization cavity, and grooves are formed on the circumferential side surface and the end surface on one side close to the air outlet channel of the base body to form the swirl channel and the air inlet section of the atomization channel.

[0020] Preferably, a protruding portion is arranged on one side of the base close to the atomization cavity, and the air inlet channel penetrates through the protruding portion;

[0034] The embodiment of the present application provides an atomization device, which forms a rotating flow field at the air outlet end of the atomization channel through a reasonable airway design, can effectively mix the aerosol evenly, and thus improve the use effect of the product.

[0035] 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.

[0036] Such as Figures 1 to 5As shown in the figure, the atomizing device in the present application includes an oil cup 1, an atomizing component 2, and a base 3. The oil cup 1 (for storing the liquid to be atomized, such as e-liquid; see the discussion below for details), the atomizing component 2 (a structure for atomizing the liquid to be atomized, see the discussion below for details), and the base 3 cooperate to form a gas diversion channel. The gas diversion channel includes an intake channel 4, an atomizing channel 6, an outlet channel 7, and a swirl channel 5 that is parallel to the atomizing channel 6. That is to say, the intake end of the atomizing channel 6 and the intake end of the swirl channel 5 are both connected to the intake channel 4, and the outlet end of the atomizing channel 6 and the outlet end of the swirl channel 5 are both connected to the outlet channel 7.

[0037] Among them, the atomizing channel 6 and the swirl channel 5 are formed in the atomizing component 2. The swirl channel 5 has at least a first outlet portion that extends in a first direction and is connected to the atomizing channel 6, and the extension line of the first outlet portion deviates from the center of the outlet port of the atomizing channel 6, so as to form a rotating flow field at the outlet end of the atomizing channel 6 by using the gas flowing out of the self-rotating flow channel 5.

[0038] During the use of the above atomizing device, a part of the gas flowing out of the intake channel 4 enters the atomizing channel 6 to participate in the formation of the aerosol and enters the outlet channel 7; another part enters the swirl channel 5 and, under the guiding action of the swirl channel 5, enters the outlet end of the atomizing channel 6 along the first direction from the first outlet portion. At the same time, since the extension line of the first outlet portion deviates from the center of the outlet port of the atomizing channel 6, when the gas flowing out of the self-rotating flow channel 5 enters the atomizing channel 6, under the guiding action of the channel wall of the atomizing channel 6, a rotating flow field will be generated in the outlet end area of the atomizing channel 6, thereby effectively mixing the aerosol evenly.

[0039] Furthermore, the swirl channel 5 also has an annular portion disposed around the outlet end of the atomizing channel 6. One end of the first outlet portion is connected to the annular portion, and the other end is connected to the outlet end of the atomizing channel 6; and, there are a plurality of first outlet portions, and the plurality of first outlet portions are evenly distributed around the outlet end of the atomizing channel 6. During the use of the atomizing device, gas flows out of a plurality of first outlet portions at the same time and disturbs the aerosol in the outlet end area of the atomizing channel 6. In this way, the effective disturbance area can be increased, and thus the disturbance effect of the gas flowing out of the self-rotating flow channel 5 in the atomizing device on the aerosol can be improved.

[0040] Even further, in the actual implementation process, the rotating flow field can be adjusted by adjusting the extension direction and / or the number of the first outlet portions to obtain the required disturbance effect. In an exemplary embodiment, such as Figure 5As shown, the number of the first outlet parts is 5, and the extending direction of the first outlet parts is the tangential direction of the gas outlet port of the atomization channel 6. In this way, during the use of the atomization device, a double reverse rotation flow field can be formed in the gas outlet end area of the atomization channel 6.

[0041] It should be noted that the swirling channel 5 mentioned above also has an annular part arranged around the gas outlet end of the atomization channel 6. Here, the annular part refers to the part with a ring-shaped flow channel shape, which can specifically be a circular ring-shaped part, an elliptical ring-shaped part, a polygonal ring-shaped part, etc.; during the implementation process, it can be adaptively designed according to needs.

[0042] In addition, the swirling channel 5 also has a second outlet part extending along the second direction and communicating with the gas outlet channel 7. The second direction is the axis direction of the gas outlet channel 7, so as to use a part of the gas flowing out of the swirling channel 5 to isolate the aerosol flowing out of the atomization channel 6 and the inner wall of the gas outlet channel 7. In this way, of the gas flowing out of the swirling channel 5, a part flows into the gas outlet end of the atomization channel 6 through the first outlet part, and another part directly flows into the gas outlet channel 7 through the second outlet part, and isolates the aerosol flowing out of the atomization channel 6 and the inner wall of the gas outlet channel 7, avoiding the contact between the aerosol and the inner wall of the gas outlet channel 7 to generate condensation, thereby improving the service life of the atomization device.

[0043] It should be noted that the first outlet part and the second outlet part can be independent flow channels, or as shown in Figure 3 、 Figure 4 and Figure 5 shown, the first outlet part and the second outlet part are combined into one body (specifically refer to the following text). In this way, the structure of the swirling channel 5 can be effectively simplified, and then it is convenient for processing to reduce the equipment cost.

[0044] Furthermore, on the basis of setting the second outlet part, as shown in Figure 2 shown, the atomization channel 6 includes an air inlet section 61 and an air outlet section 62, and the air outlet section 62 and the gas 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 swirling channel 5, the same below) between the aerosol and the inner wall of the gas 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 swirling channel 5 cannot be fully utilized due to uneven air flow distribution, resulting in the contact between a part of the inner wall of the gas outlet channel 7 and the aerosol.

[0045] Even further, in the axis direction of the gas outlet channel 7, the projection of the air outlet section 62 falls inside the projection of the gas outlet channel 7. In this way, the gas outlet channel 7 can be avoided from interfering with the air flow flowing out of the air outlet section 62, so as to ensure that the air flow flowing out of the air outlet section 62 is located inside the air flow flowing out of the first outlet part.

[0046] Further, the flow rate of the gas entering the swirl channel 5 from the intake channel 4 is Q1, and the flow rate of the gas entering the atomization channel 6 from the intake channel 4 is Q2, and Q1 < Q2. In this way, it is ensured that the flow rate of the gas entering the atomization channel 6 is sufficient, and the generation amount of the aerosol in the atomization channel 6 is not affected by the fact that part of the gas enters the swirl channel 5. In some preferred embodiments, the ratio of the flow rate of the gas entering the swirl 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 swirl 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.

[0047] In addition, in some embodiments, along the gas flow direction, the cross-sectional area of the swirl 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 fluid per unit volume is a constant), when the cross-sectional area of the swirl channel 5 decreases, the flow velocity of the gas will increase to compensate for the potential energy reduced due to the narrowing of the flow channel, and the increase in the gas flow velocity is more conducive to the gas flowing out of the spin flow channel 5 disturbing the aerosol, or forming an annular air flow to isolate the gas flowing out of the atomization channel 6 and the inner wall of the air outlet channel 7.

[0048] In addition, regarding the formation methods of the intake channel 4, the swirl channel 5, the atomization channel 6, and the air outlet channel 7, in some embodiments, as Figure 2 shown, the atomization assembly 2 includes a base body 21 and a heating wire 22. A through hole is provided at the axial position of the base body 21, and this through hole is the air outlet section 62 of the atomization channel 6. The heating wire 22 is arranged on the inner wall of the air outlet section 62, and it serves as the heat source for atomization to promote atomization so as to form an aerosol in the air outlet section 62.

[0049] Continuing as Figure 2 shown, the intake channel 4 is arranged on the base 3 of the atomization device, and the base 3 is connected to the bottom of the oil cup 1 (the connection method can be interference fit or snap connection, etc.), and cooperates with the oil cup 1 to form an atomization chamber for installing the atomization assembly 2. The air outlet channel 7 is arranged in the oil cup 1 of the atomization device, and the atomization chamber communicates the intake channel 4 and the air outlet channel 7. In the assembled state, the atomization assembly 2 is arranged in the atomization chamber, and grooves 23 are formed on the circumferential side surface of the base body 21 and the end surface close to the air outlet channel 7 to form the intake section 61 of the swirl channel 5 and the atomization channel 6.

[0050] Specifically, as Figures 2 - 5As shown, an annular groove is provided on the end face of the substrate 21 close to one side of the air outlet passage 7. This annular groove is the annular part of the swirl passage 5. There is a first side wall between the annular part and the atomization passage 6. A plurality of grooves for communicating the annular groove with both the atomization passage 6 and the air outlet passage 7 at the same time are provided on the first side wall. These grooves are the first outlet part and the second outlet part. In addition, a groove 23 communicating with the above-mentioned annular groove is provided on the circumferential side face and the end face of the substrate 21 close to one side of the air outlet passage 7. In the assembled state, the substrate 21 is arranged in the assembly cavity in a transition fit manner. At this time, the above-mentioned groove area of the substrate 21 cooperates with the inner wall of the oil cup 1 to form the swirl passage 5. In addition, as Figure 2 shown, there is a gap between the substrate 21 and the base 3. Part of the surfaces of the substrate 21 and the base 3 that form the atomization chamber cooperate to form the intake section 61.

[0051] Furthermore, as Figure 2 shown, a protrusion 31 is provided on one side of the base 3 close to the atomization chamber. The intake passage 4 penetrates through the above-mentioned protrusion 31; in the assembled state, the protrusion 31 extends into the cavity formed by the inner wall of the oil cup 1 and the groove 23, and there is a gap between the protrusion 31 and the substrate 21 to form an L-shaped intake section 61. In this way, the resistance of the gas entering the atomization passage 6 can be increased, which is beneficial to controlling the ratio of the gas entering the swirl passage 5 and the gas entering the atomization passage 6.

[0052] It should be understood that the above are only exemplary formation methods of the intake passage 4, the swirl passage 5, the atomization passage 6 and the air outlet passage 7, but the present application is not limited thereto. For example, in some embodiments, the number of intake passages 4 can be increased. Specifically, multiple intake passages 4 can be provided to communicate with the swirl passage 5 and the atomization passage 6 respectively. In this way, it is more convenient to control the ratio of the gas entering the swirl passage 5 and the gas entering the atomization passage 6.

[0053] In addition, as Figure 2 shown, the oil cup 1 in the present application includes a liquid storage cavity 11 for storing the liquid to be atomized. The liquid storage cavity 11 is arranged around the air outlet passage 7 to increase the storage capacity of the liquid storage cavity 11.
