Description

Technical Field

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

[0002] Aerosols are colloidal dispersion systems formed by small particles of solid or aerosol matrix dispersed and suspended in a gaseous medium. Since aerosols can be absorbed by the human body through the respiratory system, atomizing devices that generate aerosols by heating aerosol matrices such as medical liquids can be used in various fields such as medicine to deliver inhalable aerosols to users.

[0003] However, traditional atomizers have the problem of being difficult to inhale. Summary of the Invention

[0004] Therefore, it is necessary to provide an atomizer and electronic atomization device to address the problem of difficulty in inhaling from traditional atomizers.

[0005] According to one aspect of this application, an atomizer is provided, including a housing, the housing having an air inlet and an air outlet facing different directions, and an airflow channel communicating between the air inlet and the air outlet; the airflow channel includes an air inlet channel and an atomizing zone communicating with each other;

[0006] The air intake channel is configured to extend in a curved manner from one end near the air intake to the other end near the atomization zone.

[0007] In one embodiment, the air intake channel is configured to extend in an arc shape from one end near the air intake to one end near the atomizing zone.

[0008] In one embodiment, the air intake channel includes a first channel with one end connected to the air intake port, a second channel with one end connected to the atomizing area and extending along the axial direction of the atomizing area, and an arc-shaped channel connecting the first channel and the second channel.

[0009] In one embodiment, the first channel has a first connection port communicating with the arc-shaped channel, and the flow area of ​​the air inlet is larger than the flow area of ​​the first connection port.

[0010] In one embodiment, the air inlet extends in an arc shape around the first communication port.

[0011] In one embodiment, the air inlet has an arc-shaped edge, the center of which coincides with the central axis of the atomizing zone.

[0012] In one embodiment, the second channel has a first sidewall, and the atomizing area has a second sidewall that extends along the extension direction of the first sidewall, the second sidewall being flush with the first sidewall.

[0013] In one embodiment, the air intake channel has a second communication port communicating with the atomizing area at one end near the atomizing area;

[0014] Along the radial direction of the atomization zone, the second communication port is closer to the sidewall of the atomization zone than to the central axis of the atomization zone.

[0015] In one embodiment, the airflow channel includes at least two air intake channels spaced apart around the central axis of the atomizing zone;

[0016] The atomizing zone is connected to the second connection port of each of the air intake channels.

[0017] In one embodiment, the air inlet has a preset flow area S.

[0018] In one embodiment, the preset flow area S satisfies the following condition: 3.54 mm. 2 ≤S≤7.07mm 2 .

[0019] In one embodiment, the dimension of the air inlet along the axial direction of the atomizing zone is a, the radial dimension of the atomizing zone is 2r, and the ratio of a to r is a preset value b.

[0020] In one embodiment, the preset value b satisfies the following condition: 0.3 ≤ b ≤ 0.5.

[0021] In one embodiment, the central axis of the air outlet coincides with the central axis of the atomizing zone.

[0022] According to another aspect of this application, an electronic atomizing device is provided, including the atomizer described above.

[0023] In the aforementioned atomizer and electronic atomizing device, airflow flows into the air intake channel from the air inlet. Because the air intake channel is constructed to bend and extend from one end near the air inlet to the other end near the atomization zone, the airflow flowing in from the air inlet can flow along the side wall of the air intake channel and gradually adjust its direction to flow towards the atomization zone. This avoids a significant change in the flow direction of the airflow before entering the atomization zone, reduces the generation of eddies, and minimizes the energy loss of the airflow. This is beneficial for the airflow to carry away the aerosol on the side wall of the atomization zone as it flows from the atomization zone towards the air outlet. Furthermore, due to the low airflow resistance, it is easier to inhale the aerosol. Attached Figure Description

[0039] The inventors of this application discovered through research that the reason why it is difficult to inhale using traditional atomizers is that: In a traditional atomizer, the atomizer includes a shell and an air inlet and an air outlet arranged perpendicularly to each other on the shell. The airflow enters the shell from the air inlet, carries away the aerosol in the atomization zone of the shell, and then flows out from the air outlet. During this process, the airflow direction changes drastically before entering the atomization zone, which easily generates turbulence and causes a large loss of airflow energy, resulting in greater resistance during inhalation, thus making it difficult to inhale using traditional atomizers.

[0040] To address the difficulty of inhaling from traditional atomizers, this application presents an atomizer comprising an interconnected air intake channel and an atomization zone. The design ensures that the airflow entering from the air intake flows along the side wall of the air intake channel and gradually adjusts its direction to flow towards the atomization zone. This prevents a significant change in airflow direction before entering the atomization zone, reduces eddy currents, minimizes energy loss, and makes it easier to inhale the aerosol carried by the airflow.

[0041] Figure 1 A schematic diagram of the atomizer 10 in one embodiment of this application is shown.

[0042] Please see Figure 1 and in conjunction with reference Figure 2 An embodiment of this application provides an atomizer 10, which includes a housing 110. The housing 110 is provided with an air inlet 111 and an air outlet 112 facing different directions, and an airflow channel connecting the air inlet 111 and the air outlet 112.

[0043] The airflow channel includes an intake channel 113 and an atomizing zone 114 that are connected to each other. It can be understood that the end of the intake channel 113 away from the atomizing zone 114 is connected to the air inlet 111, and the end of the atomizing zone 114 away from the intake channel 113 is connected to the air outlet 112.

[0044] Airflow enters the intake channel 113 from the intake port 111. Since the intake channel 113 is constructed to bend and extend from one end near the intake port 111 to the other end near the atomization zone 114, the airflow flowing in from the intake port 111 can flow along the side wall of the intake channel 113 and gradually adjust its direction to flow towards the atomization zone 114. This avoids a significant change in the flow direction of the airflow before it enters the atomization zone 114, reduces the generation of eddies, and minimizes the energy loss of the airflow. This is beneficial for the airflow to carry away the aerosol on the side wall of the atomization zone 114 as it flows from the atomization zone 114 toward the outlet 112. Furthermore, due to the low airflow resistance, it is easier to absorb the aerosol.

[0045] In some embodiments, the air intake passage 113 is configured to extend in an arc shape from one end near the air intake 111 to the other end near the atomizing region 114.

[0046] Understandably, the sidewall of the air intake channel 113 is curved and extended in an arc shape. In this way, the airflow entering the air intake channel 113 can flow well along the sidewall of the air intake channel 113. That is to say, the sidewall of the air intake channel 113 can guide the airflow to gradually adjust its flow direction, which can better reduce the generation of vortices, reduce the energy loss of the airflow, and make it easier to absorb aerosols.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 The air intake channel 113 includes a first channel 1131 connected to the air intake port 111 at one end, a second channel 1132 connected to the atomizing area 114 at one end and extending along the axial direction of the atomizing area 114, and an arc-shaped channel 1133 connecting the first channel 1131 and the second channel 1132.

[0048] By utilizing the arc-shaped channel 1133, the airflow entering the first channel 1131 can gradually change its flow direction as it passes through the arc-shaped channel 1133. By utilizing the second channel 1132 extending along the axial direction of the atomization zone 114, the airflow entering the second channel 1132 can flow towards the atomization zone 114 in a roughly axial direction. The arc-shaped transition formed by the arc-shaped channel 1133 can reduce the generation of eddies, resulting in less energy loss of the airflow, improving the airflow's ability to carry aerosols, and also improving the inhalation effect.

[0049] In some embodiments, the first channel 1131 has a first connection port 11311 communicating with the arc-shaped channel 1133, and the flow area of ​​the air inlet 111 is larger than the flow area of ​​the first connection port 11311.

[0050] Thus, the airflow entering the first channel 1131 through the air inlet 111 undergoes a deceleration process as it flows toward the first connecting port 11311, allowing the airflow to flow more smoothly toward the first connecting port 11311. This is more conducive to reducing the generation of eddies and reducing the energy loss of the airflow, thereby improving the inhalation effect and the airflow's ability to carry aerosols.

[0051] In some embodiments, the air inlet 111 extends in an arc shape around the first communication port 11311.

[0052] It is understandable that the orthographic projection of the first channel 1131 onto the bottom end of the housing 110 is roughly fan-shaped (which can be combined with...). Figure 4 (To understand).

[0053] Without increasing the volume occupied by the housing 110, the air inlet 111 is curved and extended around the first connecting port 11311 in an arc shape, which helps to increase the flow area of ​​the air inlet 111. The airflow entering the air inlet 111 can flow towards the first connecting port 11311 in the radial direction of the air inlet 111, and can converge to the first connecting port 11311. The airflow direction is gradually changed through the arc-shaped channel 1133, and finally flows to the atomization zone 114. In this way, on the one hand, the air intake can be increased, and the aerosol generated on the side wall of the atomization zone 114 can be carried away in time, which can improve the airflow's ability to carry aerosol. On the other hand, the energy loss of the airflow is small, and the inhalation effect is better.

[0054] In some embodiments, please refer to Figure 3 The air inlet 111 has an arc-shaped edge 1111, and the center of the arc-shaped edge 1111 coincides with the central axis of the atomizing area 114.

[0055] Understandably, the air inlet 111 extends in an arc around the center line of the atomizing zone 114.

[0056] The airflow entering the air intake channel 113 through the air inlet 111 can gradually change direction and flow towards the atomization zone 114, and can promptly carry away the aerosol generated on the side wall of the atomization zone 114. Since the center of the arc edge 1111 coincides with the center line of the atomization zone 114, the airflow and the aerosol it carries can gradually move towards the center of the atomization zone 114 as it flows from the atomization zone 114 to the air outlet 112, which is more conducive to the delivery of aerosol to the air outlet 112.

[0057] In this embodiment, the sidewall of the first channel 1131 includes a radial extension that extends radially along the arc edge 1111, which facilitates the flow of air along the radial extension to the first communication port 11311.

[0058] In some embodiments, please refer to Figure 2The second channel 1132 has a first sidewall 11321, and the atomizing area 114 has a second sidewall 1141 that extends along the extension direction of the first sidewall 11321, and the second sidewall 1141 is flush with the first sidewall 11321.

[0059] Since the second sidewall 1141 extends along the extension direction of the first sidewall 11321 and is flush with the first sidewall 11321, the airflow flowing towards the atomization zone 114 through the second channel 1132 along the axial direction of the atomization zone 114 can flow along the first sidewall 11321 and continue to flow along the second sidewall 1141. This is beneficial for the airflow to carry away the aerosol generated at the sidewall of the atomization zone 114, reducing the energy loss of the airflow while improving the airflow's ability to carry aerosols and also improving the inhalation effect.

[0060] In some embodiments, please refer to Figure 2 The intake passage 113 has a second communication port 11322 at one end near the atomizing area 114, which communicates with the atomizing area 114. Along the radial direction of the atomizing area 114, the second communication port 11322 is closer to the side wall of the atomizing area 114 than the central axis of the atomizing area 114.

[0061] It is understandable that the second connection port 11322 is located at the end of the second channel 1132 away from the arc-shaped channel 1133.

[0062] Thus, the second connecting port 11322 is positioned close to the side wall of the atomizing zone 114, allowing the airflow entering the air intake channel 113 to better contact the aerosol generated on the side wall of the atomizing zone 114 after entering the atomizing zone 114, thereby timely removing the aerosol generated on the side wall of the atomizing zone 114. This helps to improve the airflow's ability to carry aerosols, enhances wall heat exchange, avoids local high temperatures that cause carbon buildup and burnt smells, and increases the concentration of aerosols inhaled.

[0063] In some embodiments, the central axis of the second communication port 11322 is parallel to the central axis of the atomizing region 114, and the cross-sectional shape of the second communication port 11322 is circular, and the cross-sectional shape of the atomizing region 114 is also circular.

[0064] It can increase the contact area between the airflow and the sidewall of the second connecting port 11322 and between the airflow and the sidewall of the atomization zone 114, which can better remove the aerosol generated at the sidewall of the atomization zone 114, and also help improve the airflow's ability to carry aerosols.

[0065] In some embodiments, the radial dimension of the second communication port 11322 is smaller than the radial dimension of the atomizing region 114.

[0066] In this way, the airflow in the intake channel 113 enters the atomization zone 114 with a larger diameter through the smaller diameter second connecting port 11322, resulting in an acceleration process. Combined with the fact that the second connecting port 11322 is closer to the side wall of the atomization zone 114 along the radial direction of the atomization zone 114, the airflow can more quickly carry away the aerosol generated at the side wall of the atomization zone 114, avoiding local high temperature from producing carbon deposits and burnt smells, and also improving the airflow's ability to carry aerosols.

[0067] In some embodiments, along the radial direction of the atomizing region 114, the distance between the second communication port 11322 and the central axis of the atomizing region 114 is A, and the radial dimension of the second communication port 11322 is B, where A is greater than or equal to B.

[0068] If A equals B, the second connecting port 11322 can be made to be closer to the side wall of the atomizing region 114 along the radial direction of the atomizing region 114, while ensuring the flow area of ​​the second connecting port 11322, which is beneficial to improving the airflow's ability to carry aerosols.

[0069] If A is greater than B, then the second connecting port 11322 is closer to the side wall of the atomization zone 114 along the radial direction of the atomization zone 114, which is more conducive to improving the airflow's ability to carry aerosols.

[0070] In some embodiments, the central axis of the air outlet 112 coincides with the central axis of the atomizing zone 114.

[0071] This design makes it easier for the airflow in the atomization zone 114 and the aerosol carried by the airflow to be transported to the air outlet 112.

[0072] In some embodiments, the housing 110 is further provided with an exhaust channel 115 communicating between the atomizing zone 114 and the air outlet 112, wherein the radial dimension of the exhaust channel 115 is greater than the radial dimension of the atomizing zone 114.

[0073] With this configuration, the airflow will accelerate as it flows from the atomization zone 114 to the exhaust channel 115, which is more conducive to the airflow in the atomization zone 114 and the aerosol carried by the airflow being transported to the exhaust port 112.

[0074] In some embodiments, the exhaust passage 115 includes an outlet section near the air outlet 112, and the radial dimension of the outlet section of the exhaust passage 115 gradually increases along the direction from the atomization zone 114 toward the air outlet 112.

[0075] This helps to increase the outward flow speed of the airflow in the outlet section of the exhaust channel 115, so that the user can better inhale aerosols at the air outlet 112.

[0076] In some embodiments, the airflow channel includes at least two air intake channels 113 spaced apart around the central axis of the atomizing region 114, and the atomizing region 114 is connected to the second communication port 11322 of each air intake channel 113.

[0077] Airflow can flow into the atomization zone 114 through multiple air intake channels 113, increasing the air intake volume and also carrying away the aerosol generated on the side wall of the atomization zone 114 in a timely manner, thus increasing the aerosol carrying capacity of the airflow.

[0078] In some embodiments, the air inlet 111 has a preset flow area S.

[0079] If the flow area of ​​the air inlet 111 is too small, it will affect the air intake and inhalation effect of the atomizer 10. If the flow area of ​​the air inlet 111 is too large, the airflow will converge at the center of the channel at a preset flow rate too close to the air outlet 112, which is not conducive to the early accumulation of aerosols. Therefore, the air inlet 111 needs to have a preset flow area S. On the one hand, this can increase the flow area of ​​the air inlet 111, thereby increasing the air intake. On the other hand, it is conducive to the early accumulation of aerosols, thereby increasing the aerosol concentration.

[0080] In some embodiments, the preset flow area S satisfies the following condition: 3.54 mm 2 ≤S≤7.07mm 2 .

[0081] For example, the air inlet 111 extends in an arc shape around the central axis of the atomizing zone 114, and the central angle α of the arc edge 1111 of the air inlet 111 is 30°, 60°, 90°, 120° and 150° respectively (the central angle α of the arc edge 1111 can be combined with...) Figure 4 (For understanding), the dimension of the air inlet 111 along the axial direction of the atomizing zone 114 is a (which can be combined with...). Figure 5 (For understanding), the radial dimension of the atomization zone 114 is 2r (which can be combined with...) Figure 5 (For understanding), the ratio of a to r is 0.5, r is 1.3mm, and the distance between the air inlet 111 and the central axis of the atomizing zone 114 along the radial direction of the atomizing zone 114 is R (which can be combined with...). Figure 5(For understanding), R is 2.6mm, the flow rate of the outlet 112 is constant at 18.3ml / s, and the inlet relative pressure is 0Pa, consistent with atmospheric pressure. As shown in Table 1 below, as the central angle of the arc edge 1111 gradually increases, the flow area of ​​the inlet 111 also gradually increases. However, when the airflow converges at the center of the channel at a preset flow rate (the channel includes the atomization zone 114 and the exhaust channel 115), the position Z along the axis of the atomization zone 114 also gradually increases. This results in the airflow converging at the center of the channel at a preset flow rate being too close to the outlet 112, which is not conducive to the early accumulation of aerosols.

[0082] Therefore, the central angle α of the arc edge 1111 can be set to 60°≤α≤120°, which also allows the preset flow area S to meet the following condition: 3.54mm. 2 ≤S≤7.07mm 2 This increases the air intake and facilitates earlier aerosol aggregation, thereby increasing the aerosol concentration and achieving a better inhalation effect.

[0083] Table 1 provides a summary of the flow area and Z of the air inlet 111 under different values ​​of the central angle α of the arc edge 1111.

[0084]

[0085]

[0086] In some embodiments, the dimension of the air inlet 111 along the axial direction of the atomizing region 114 is a, the radial dimension of the atomizing region 114 is 2r, and the ratio of a to r is a preset value b.

[0087] If the ratio of a to r is too small, it will not be conducive to the early aggregation of aerosols. If the ratio of a to r is too large, it will affect the airflow's ability to carry aerosols. Therefore, the ratio of a to r needs to be set to a preset value b, which will not only facilitate the early aggregation of aerosols and thus increase the concentration of aerosols, but also improve the airflow's ability to carry aerosols.

[0088] In some embodiments, the preset value b satisfies the following condition: 0.3≤b≤0.5.

[0089] For example, b is set to 0.2, 0.3, 0.4, 0.5, and 0.6 respectively, the central angle α of the arc edge 1111 can be set to 60°, r is 1.3 mm, R is 2.6 mm, the flow rate of the outlet 112 is constant at 18.3 ml / s, and the inlet relative pressure is 0 Pa, consistent with atmospheric pressure. As shown in Table 2, when the preset value b gradually increases, the position Z along the axis of the atomization zone 114 when the airflow converges at the center of the channel at the preset flow rate gradually decreases. That is, the farther the airflow is from the outlet 112 when it converges at the center of the channel at the preset flow rate, the more conducive it is to the earlier aerosol aggregation, thereby increasing the aerosol concentration. However, the radial distance between the high-speed zone of the airflow and the sidewall of the atomization zone 114 gradually increases, which weakens the airflow's ability to carry aerosols. Therefore, the preset value b needs to meet the following condition: 0.3≤b≤0.5, which can ensure that the airflow's ability to carry aerosols is not affected, while increasing the concentration of aerosols to achieve a better inhalation effect.

[0090] Table 2 provides a summary of the radial distances between Z and the high-speed region of the airflow and the sidewalls of the atomization zone 114 when the ratio of a to r varies.

[0091]

[0092] In some embodiments, please refer to Figure 6 The housing 110 is provided with a heating element 120, and an atomizing zone 114 is formed on the inner wall of the heating element 120. The outer wall of the heating element 120 and the inner wall of the housing 110 define a liquid storage cavity 130 for containing the aerosol matrix. The heating element 120 is used to receive the aerosol matrix in the liquid storage cavity 130 and atomize the received aerosol matrix in the atomizing zone 114. That is, the heating element 120 atomizes the aerosol matrix to form an aerosol, and the aerosol can be generated at the side wall of the atomizing zone 114.

[0093] After the airflow enters the corresponding air intake channel 113 through the air intake 111, it can flow well along the side wall of the air intake channel 113, making it less prone to eddies and resulting in minimal energy loss. Furthermore, after the airflow enters the larger diameter atomization zone 114 from the smaller diameter first connecting port 11311, the airflow can pass through the side wall of the atomization zone 114 more quickly, thereby concentrating the high-speed zone formed by the airflow at the side wall of the atomization zone 114. In other words, the high-speed zone formed by the airflow can be concentrated in the area where aerosols are generated, so as to carry away the aerosols generated by atomization in a timely manner. In addition, as the airflow gradually flows towards the air outlet 112, the high-speed zone formed by the airflow will also gradually converge towards the center of the air outlet 112, increasing the aerosol concentration at the air outlet 112.

[0094] In some embodiments, the airflow channel includes two air inlet channels 113 symmetrically arranged around the central axis of the atomizing zone 114, and the preset flow area S satisfies the following condition: 3.54 mm. 2 ≤S≤7.07mm 2 Furthermore, the preset value b satisfies the following condition: 0.3 ≤ b ≤ 0.5. For example, the central angle α of the arc edge 1111 is 60°, and the preset flow area S is 3.54 mm². 2 b is 0.5 respectively, the central angle α of the arc edge 1111 can be set to 60°, r is 1.3mm, R is 2.6mm, the flow rate of the outlet 112 is constant at 18.3ml / s, and the inlet relative pressure is 0Pa, which is consistent with atmospheric pressure.

[0095] Figure 7 The velocity distribution diagram of the airflow is given. Figure 8 The cross-sectional velocity distribution data of the airflow is given (four cross-sections are selected along the central axis of the atomization zone 114, and the coordinates of the four cross-sections along the central axis of the atomization zone 114 are z = 0, z = 0.2, z = 0.4, and z = 0.6, respectively). Combined with... Figure 7 and Figure 8 It can be seen that the atomizer 10 utilizes the Coanda effect in aerodynamics, allowing the airflow to flow along the streamlined wall of the air intake channel 113 before entering the atomization zone 114, making it less prone to eddy currents and resulting in minimal energy loss. Figure 8 In the diagram, the horizontal axis represents the radial distance between the airflow and the sidewall of the atomization zone 114, and the vertical axis represents the airflow velocity. Clearly, the high-speed airflow is concentrated 1 mm from the center of the atomization zone 114. Combined with the value of r = 1.3 mm, this indicates that the high-speed airflow is concentrated near the sidewall of the atomization zone 114. Thus, after the airflow enters the atomization zone 114, the high-speed airflow is concentrated near the sidewall, which helps to promptly remove the aerosols generated by atomization. Furthermore, as the airflow gradually moves towards the outlet 112, the high-speed airflow gradually converges towards the center of the exhaust channel 115. This facilitates the transport of aerosols to the outlet 112, increasing the aerosol concentration at the outlet 112. Additionally, the high-speed airflow can promptly remove heat from the atomization zone 114, preventing excessively high local temperatures that could lead to carbon buildup and a burnt smell.
