Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an atomizer and an electronic atomization device. Background Art

[0002] Aerosols are colloidal dispersions composed of small solid or liquid particles dispersed and suspended in a gaseous medium. Because aerosols can be absorbed through the respiratory system, they offer users a novel alternative absorption method. For example, electronic atomization devices, which heat liquid or solid aerosol-generating substrates to produce aerosols, are used in various fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Typically, electronic atomization devices atomize an aerosol-generating matrix, a material that produces an aerosol upon atomization. However, in conventional electronic atomization devices, if too much aerosol-generating matrix is supplied to the liquid-absorbing element and too little time for atomization, a liquid explosion may occur, causing the aerosol-generating matrix to be directly inhaled into the user's mouth, thus affecting the user's ability to use the electronic atomization device. Utility Model Content

[0004] Based on this, it is necessary to provide an atomizer and an electronic atomization device to address the problem that traditional electronic atomization devices are prone to sucking in liquid due to explosive liquid.

[0005] An atomizer, comprising:

[0006] A housing and an air outlet pipe, wherein the air outlet pipe is sleeved in the housing, and a liquid storage cavity is defined between the housing and the air outlet pipe;

[0007] an atomizing assembly disposed within the housing and comprising a support tube, a liquid guide member, and a heating element; the support tube having a liquid inlet passage extending axially therethrough and communicating with the liquid storage chamber; a liquid inlet hole communicating with the liquid inlet passage being formed on the support tube; the liquid guide member being sleeved on the support tube; and the heating element being disposed outside the liquid guide member;

[0008] In which, the axial direction of the air outlet pipe intersects with the axial direction of the support tube, the air outlet pipe is located downstream of the air flow of the atomizer assembly, and the air outlet pipe has an air inlet facing the atomizer assembly, and the center of the orthographic projection of the air inlet toward the outer peripheral surface of the support tube is offset from the center of the liquid inlet hole.

[0009] In the above-mentioned atomizer, the air outlet pipe has an air inlet toward the atomizing assembly, and the center of the orthographic projection of the air inlet toward the outer circumference of the support tube is offset from the center of the liquid inlet. It is understandable that the air inlet is generally circular or elliptical, with the center of the air inlet being the center of the circle, or the air inlet can also be of other shapes, with the center of the air inlet being the geometric center of the corresponding shape. Similarly, the liquid inlet is generally a symmetrical figure, for example, the liquid inlet is in the shape of a waist-shaped hole, a circular hole, or an elliptical hole, and the center of the liquid inlet is the geometric center of the corresponding shape. Moreover, when too much liquid is supplied, the position of the outer surface of the atomizing assembly corresponding to the liquid supply port is prone to produce explosive liquid. By offsetting the center of the orthographic projection of the air inlet toward the outer circumference of the support tube with the center of the liquid inlet, the liquid inlet is offset from the air inlet, thereby preventing the liquid inlet from being directly opposite the air inlet, and preventing the explosive liquid produced at the position of the liquid inlet on the outer surface of the atomizing assembly corresponding to the liquid supply port when too much liquid is supplied directly from flowing to the air inlet, thereby preventing the user from inhaling liquid, and improving the user experience.

[0010] In one embodiment, a first axis of the liquid inlet passing through its own center in the direction of the liquid inlet toward the liquid guide member is staggered with a second axis of the air outlet pipe passing through the center of the air inlet in the direction of the atomizer assembly toward the air outlet pipe.

[0011] In one embodiment, the first axis and the second axis are staggered in the radial direction of the air outlet pipe.

[0012] In one embodiment, the diameter of the air outlet pipe is D, the width of the liquid inlet hole in a direction perpendicular to the first axis is B, and the offset distance between the first axis and the second axis in the radial direction of the air outlet pipe is A, A≥(D+B) / 2.

[0013] In one embodiment, the support tube has a first opening area, a first closed area and a second opening area. The first closed area is located between the first opening area and the second opening area along the axial direction of the support tube, and the orthographic projection of the air inlet toward the outer circumferential surface of the support tube is located within the first closed area. The liquid inlet hole is provided in at least one of the first opening area and the second opening area.

[0014] In one embodiment, the air outlet pipe has a longitudinal section passing through its own central axis and intersecting the axial direction of the support pipe, and there is a deflection angle between the projection of the first axis toward the longitudinal section and the projection of the second axis toward the longitudinal section.

[0015] In one embodiment, the deflection angle is θ, 30°≤θ≤270°.

[0016] In one embodiment, the support tube has a third open area and a second closed area, the third open area is distributed around the outer circumference of the support tube along the circumference of the support tube, and the third open area has a first end and a second end spaced apart in the circumferential direction of the support tube, the second closed area is distributed between the first end and the second end, the orthographic projection of the air inlet toward the outer circumferential surface of the support tube is located in the second closed area, and the liquid inlet is provided in the third open area.

[0017] In one embodiment, the support tube has a first opening area, a first closed area and a second opening area. The first closed area is located between the first opening area and the second opening area along the axial direction of the support tube, and the first closed area includes a closed main area and a fourth opening area. The fourth opening area is distributed around the outer circumference of the support tube along the circumference of the support tube, and the fourth opening area has a third end and a fourth end spaced apart in the circumferential direction of the support tube. The closed main area is distributed between the third end and the fourth end. The orthographic projection of the air inlet toward the outer circumferential surface of the support tube is located in the closed main area, and the liquid inlet is provided in at least one of the first opening area, the second opening area and the third opening area.

[0039] See Figures 1-6 In some embodiments of the present application, a nebulizer 100 is provided, comprising a housing 10, an outlet pipe 30, and an atomizing assembly 50. The outlet pipe 30 is disposed within the housing 10, defining a liquid storage chamber between the housing 10 and the outlet pipe 30 for storing an aerosol-forming substrate. The atomizing assembly 50 is disposed within the housing 10 and is configured to heat and atomize the aerosol-forming substrate. The atomized aerosol is then drawn into the user's mouth for consumption.

[0040] The atomizing assembly 50 includes a support tube 70, a liquid guide member 80 and a heating member 90. The support tube 70 has a liquid inlet channel 71 that runs axially through and is connected to the liquid storage chamber. The support tube 70 is provided with a liquid inlet hole 73 that is connected to the liquid inlet channel 71. The heat-conducting member is sleeved on the support tube 70, and the heating member 90 is arranged outside the heat-conducting member. In this way, the liquid-absorbing member is arranged on the support tube 70, and the aerosol-generating matrix in the liquid storage chamber can enter the liquid inlet channel 71 and flow to the liquid-absorbing member through the liquid inlet hole 73. Liquid is supplied from the inside of the liquid-absorbing member, which makes liquid supply more convenient. In addition, the axial direction of the air outlet pipe 30 intersects with the axial direction of the support tube 70. For example, the air outlet pipe 30 is arranged in the vertical direction, and the support tube 70 is placed in the horizontal direction. The heating element 90 at the periphery of the atomizing assembly 50 atomizes the aerosol-generating matrix absorbed in the liquid-guiding element 80 into aerosol. During the atomization process, the air flow flows around the periphery of the atomizing assembly 50 to the air outlet pipe 30 to carry the aerosol out.

[0041] The outlet pipe 30 has an air inlet 32 facing the atomizer assembly 50. The center of the orthographic projection of the air inlet 32 toward the outer circumference of the support tube 70 is offset from the center of the liquid inlet hole 73. It is understood that the air inlet 32 is generally circular or elliptical in shape, with the center of the air inlet 32 being the center of the circle, or the air inlet 32 can also be of other shapes, with the center of the air inlet 32 being the geometric center of the corresponding shape. Similarly, the liquid inlet hole 73 is generally a symmetrical shape, for example, a waist-shaped hole, a circular hole, or an elliptical hole, with the center of the liquid inlet hole 73 being the geometric center of the corresponding shape. In addition, when too much liquid is supplied, the outer surface of the atomizing component 50 corresponding to the liquid supply port is prone to produce liquid explosion. The air inlet 32 is offset with the center of the positive projection of the outer peripheral surface of the support and the center of the liquid inlet hole 73, which is equivalent to offsetting the liquid inlet hole 73 and the air inlet 32, preventing the liquid inlet hole 73 from facing the air inlet 32, and preventing the liquid explosion generated at the liquid inlet hole 73 on the outer surface of the atomizing component 50 corresponding to the liquid supply port when too much liquid is supplied from flowing directly to the air inlet 32, preventing the user from inhaling the liquid, and improving the user experience.

[0042] Furthermore, a first axis E of the liquid inlet hole 73 passing through its own center in the direction toward the liquid guide member 80 is offset from a second axis F of the outlet pipe 30 passing through the center of the air inlet 32 in the direction toward the air outlet pipe 30 from the atomizer assembly 50. The first axis E corresponds to the liquid inlet direction from the liquid inlet hole 73 toward the liquid guide member 80, and the second axis F corresponds to the air outlet direction from the atomizer assembly 50 toward the air inlet 32. The offset between the first axis E and the second axis F is equivalent to offsetting the area of the liquid inlet hole 73 where liquid is fully supplied and prone to liquid explosion from the air outlet direction, thereby preventing the explosive liquid from being directly inhaled into the user's mouth through the air inlet 32, thereby affecting the user's experience.

[0043] See Figure 4-Figure 5According to some embodiments of the present application, the first axis E and the second axis F are offset radially from each other in the outlet pipe 30. This is equivalent to offsetting the liquid inlet hole 73, which is directly opposite the air inlet 32, by a certain distance along the radial direction of the outlet pipe 30. This offsets the liquid inlet hole 73 from the air inlet 32, thereby preventing the explosive liquid from flowing directly into the air inlet 32 and being inhaled into the user's mouth. Specifically, in one embodiment, the support tube 70 is perpendicular to the outlet pipe 30, and the liquid inlet hole 73 is offset by a certain distance along the axial direction of the support tube 70 to achieve the offset from the air inlet 32.

[0044] Furthermore, the diameter of the outlet pipe 30 is D, the width of the liquid inlet hole 73 in a direction perpendicular to the first axis E is B, and the offset distance between the first axis E and the second axis F in the radial direction of the outlet pipe 30 is A, where A ≥ (D + B) / 2. This increases the distance between the first axis E of the liquid inlet hole 73 and the second axis F of the air inlet 32, allowing the liquid inlet hole 73 to be completely offset from the air inlet 32, thereby effectively preventing the explosive liquid from being drawn into the user's mouth. It is understood that in other embodiments, the distance between the first axis E and the second axis F can be set to be smaller, with the liquid inlet hole 73 partially offset from the air inlet 32, which can also reduce the probability of the explosive liquid being drawn into the user's mouth.

[0045] In some embodiments, the support tube 70 has a first opening region 75, a first enclosed region 74, and a second opening region 76. Along the axial direction of the support tube 70, the first enclosed region 74 is located between the first opening region 75 and the second opening region 76. The orthographic projection of the air inlet 32 toward the outer circumference of the support tube 70 is located within the first enclosed region 74. A liquid inlet hole 73 is defined within at least one of the first opening region 75 and the second opening region 76. This effectively divides the support tube 70 into three regions along its axial direction. The first enclosed region 74 in the middle corresponds to the air inlet 32 of the air outlet pipe 30. The first enclosed region 74 does not define a liquid inlet hole 73, but only defines a liquid inlet hole 73 in the first opening region 75 and / or the second opening region 76. This prevents the liquid inlet hole 73 from directly facing the air inlet 32.

[0046] See Figure 6 According to some embodiments of the present application, the air outlet pipe 30 has a longitudinal section G passing through its own central axis and intersecting with the axial direction of the support tube 70. There is a deflection angle between the projection of the first axis E toward the longitudinal section G and the projection of the second axis F toward the longitudinal section G, which is equivalent to the deflection between the first axis E of the liquid inlet hole 73 and the second axis F of the air inlet 32 in the circumferential direction of the support tube 70. The first axis E and the second axis F are not parallel, and the liquid inlet hole 73 and the air inlet 32 will not be completely opposite, thereby preventing the explosive liquid generated at the liquid inlet hole 73 corresponding to the surface of the atomization component 50 from being directly sucked into the air inlet 32 and then into the user's mouth, preventing the user from inhaling the liquid.

[0047] Furthermore, the deflection angle is θ, 30°≤θ≤270°. This means that the first axis E of the liquid inlet pipe does not exist within a range of 30° clockwise and counterclockwise deflection relative to the second axis F in the longitudinal cross section G. The liquid inlet hole 73 is rotated along the circumference of the support tube 70 to prevent the liquid inlet hole 73 from facing the air inlet 32.

[0048] In some embodiments, the support tube 70 has a third open area 78 and a second closed area 77. The third open area 78 is distributed around the outer circumference of the support tube 70 along the circumference of the support tube 70, and the third open area 78 has a first end and a second end spaced apart in the circumferential direction of the support tube 70. The second closed area 77 is distributed between the first end and the second end. The orthographic projection of the air inlet 32 toward the outer circumferential surface of the support tube 70 is located in the second closed area 77, and a liquid inlet hole 73 is provided in the third open area 78. In this way, the side between the first end and the second end of the third opening area 78 facing away from the air inlet 32 is the third opening area 78, and the side between the first end and the second end facing the air inlet 32 is the second closed area 77. No liquid inlet hole 73 is opened in the second closed area 77, and the liquid inlet hole 73 is opened only in the third opening area 78, thereby preventing the liquid inlet hole 73 from facing the air inlet 32, preventing the splashing droplets during the explosion from being directly sucked into the air inlet 32 and then entering the user's mouth, preventing the liquid from being sucked into the air inlet 32 and affecting the user's suction experience.

[0049] Optionally, the angle range between the first end and the second end through the second closed area 77 is 50°-70°, for example, the angle range between the first end and the second end through which the second closed area 77 is fastened is 65°, thereby forming a second closed area 77 facing the air inlet 32 to prevent the liquid inlet hole 73 from facing the air inlet 32.

[0050] According to some embodiments of the present application, the support tube 70 has a first opening area 75, a first closed area 74 and a second opening area 76. The first closed area 74 is located between the first opening area 75 and the second opening area 76 along the axial direction of the support tube 70, and the first closed area 74 includes a closed main area and a fourth opening area. The fourth opening area is distributed around the outer circumference of the support tube 70 along the circumference of the support tube 70, and the fourth opening area has a third end and a fourth end spaced apart in the circumferential direction of the support tube 70. The closed main area is distributed between the third end and the fourth end. The orthographic projection of the air inlet 32 toward the outer circumferential surface of the support tube 70 is located in the closed main area. A liquid inlet hole 73 is provided in at least one of the first opening area 75, the second opening area 76 and the third opening area 78.

[0051] That is, the outer surface of the support tube 70 is divided into three major areas along the axial direction of the support tube 70, and the middle first closed area 74 is further divided along its own circumference into a closed main area facing the air inlet 32 and a fourth opening area offset from the air inlet 32. In this way, not only can the liquid inlet hole 73 be opened in the first opening area 75 and the second opening area 76, but the liquid inlet hole 73 can also be opened in the fourth opening area. The liquid inlet hole 73 in the fourth opening area is deflected along the circumference of the support tube 70 to be offset from the air inlet 32, which can also prevent the liquid inlet hole 73 from facing the air inlet 32.

[0052] According to some embodiments of the present application, the offset distance A between the first axis E and the second axis F in the radial direction of the outlet pipe 30 is ≥ (D+B) / 2, and there is a deflection angle θ=0° between the projection of the first axis E onto the longitudinal section G and the projection of the second axis F onto the longitudinal section G. That is, the liquid inlet hole 73 on the support tube 70 is completely offset from the air inlet 32 in the radial direction of the outlet pipe 30. FIG7 (a) shows the airflow distribution diagram in this case. It can be seen that the airflow starts from the liquid inlet holes 73 on both sides, hits the inner wall, and then converges to the outlet pipe 30 to fly out. FIG7 (b) is a schematic diagram of the flow simulation of the explosive droplets in this case. It can be seen that the trajectory of the explosive droplets starting from the liquid inlet hole 73 mostly hits the inner wall of the atomization chamber, thereby preventing the droplets from flying directly out of the air inlet 32 and entering the user's mouth.

[0053] According to some implementations of the present application, the offset distance A between the first axis E and the second axis F in the radial direction of the outlet pipe 30 is 0, and the deflection angle θ between the projection of the first axis E onto the longitudinal section G and the projection of the second axis F onto the longitudinal section G is in the range of 30°≤θ≤270°. This means that the liquid inlet hole 73 on the support tube 70 is deflected in the circumferential direction of the support tube 70 to be misaligned with the air inlet 32. FIG8(a) shows the airflow distribution diagram in this case, from which it can be seen that the airflow originates from the liquid inlet holes 73 on both sides, strikes the inner wall, and then converges to the outlet pipe 30 and flies out. FIG8(b) shows a flow simulation diagram of the explosive droplets in this case, from which it can be seen that the trajectory of the explosive droplets originating from the liquid inlet holes 73 mostly strikes the inner wall of the atomization chamber, thereby preventing the droplets from flying directly out of the air inlet 32 and entering the user's mouth.

[0054] In contrast, in a conventional design, the offset distance A between the first axis E and the second axis F in the radial direction of the outlet pipe 30 is 0, and the projection of the first axis E onto the longitudinal section G and the projection of the second axis F onto the longitudinal section G are offset by an angle θ = 0°, meaning that the liquid inlet 73 is directly opposite the air inlet 32. Figure 9(a) shows the airflow distribution diagram for this situation, which shows that the airflow passes directly through the outlet and then exits the outlet pipe 30. Figure 9(b) shows a flow simulation diagram of explosive droplets in this situation, which shows that the vast majority of small explosive droplets are carried out of the outlet pipe 30 by the airflow, meaning that explosive droplets can enter the user's mouth through the outlet pipe 30 and cause leakage during suction.

[0055] See Figure 10 According to some embodiments of the present application, an electronic atomization device 300 is also provided, comprising a battery assembly 200 and the atomizer 100 described in any of the above embodiments. The battery assembly 200 is used to power the atomizer 100, and the atomizer 100 heats the atomized aerosol to generate a matrix after being powered on.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0057] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
