Description

Technical Field

[0002] For an atomizer using flat ceramics, a groove is usually set at the bottom of the oil bin, and the bottom wall of the groove is lower than the bottom wall of the oil bin, and the flat ceramics are assembled in the groove. Generally, only a small amount of atomized liquid is stored in the groove. When the atomized liquid in the groove is consumed, the atomized liquid above needs to be replenished in time to meet the atomization needs of the ceramics. However, for atomized liquid with higher viscosity, the temperature needs to reach about 60° to improve its fluidity, so that the oil can flow into the groove in time and then flow to the ceramics to meet the atomization needs. Since the groove is a certain distance away from the bottom of the oil bin, the heat on the ceramics cannot be transferred to the oil bin in time, resulting in the inability to continuously add oil to the oil with higher viscosity, and the heating element is prone to dry burning, which makes the ceramics have a burnt smell, affecting the user experience.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] See also Figure 1-2 The embodiment of the utility model provides an atomizer, which is provided with a liquid storage chamber 1, the liquid storage chamber 1 has a bottom wall 11 and a peripheral side wall 12 surrounding the bottom wall 11, and the bottom wall 11 is provided with a through hole 110; the atomizer also includes an atomizer core 3 and a heat conductor 2, the atomizer core 3 is installed on the bottom wall 11, and is connected with the liquid storage chamber 1 through the through hole 110; the heat conductor 2 includes a main body 21 integrally formed on the inner surface of the bottom wall 11 and covering the inner surface of the bottom wall 11, the main body 21 is provided with an avoidance hole 210 at the position of the through hole 110, and the atomizer core 3 is exposed in the avoidance hole 210.

[0027] In the embodiment of the utility model, the atomizer core 3 is connected to the liquid storage chamber 1 through the through hole 110, the main body 21 of the heat conductor 2 covers the inner surface of the bottom wall 11 and is provided with an avoidance hole 210 at the position of the through hole 110, and the atomizer core 3 is exposed in the avoidance hole 210, so that the atomized liquid in the liquid storage chamber 1 can flow to the atomizer core 3 through the avoidance hole 210 and the through hole 110. In addition, the atomizer core 3 is assembled on the bottom wall 11, and the main body 21 of the heat conductor 2 is integrally formed on the inner surface of the bottom wall 11. Therefore, on the one hand, the heat transfer distance between the atomizer core 3 and the heat conductor 2 can be reduced, so that the heat of the atomizer core 3 when working can be directly or indirectly transferred to the heat conductor through the bottom wall 11, thereby improving the heat transfer effect; on the other hand, the contact area between the heat conductor 2 and the atomized liquid in the liquid storage chamber 1 can be increased, and the temperature of the atomized liquid in the liquid storage chamber 1 can be increased by the heat conduction effect of the heat conductor 2 before the atomized liquid is heated and atomized, thereby reducing the viscosity of the atomized liquid in the liquid storage chamber 1 and improving the fluidity of the atomized liquid, so that the atomized liquid in the liquid storage chamber 1 can flow to the atomizer core 3 in time, which can effectively prevent the atomizer core 3 from burning dry and producing a burnt smell, thereby improving the user experience.

[0028] Furthermore, the heat conductor 2 further includes an extension portion 22 extending along the axial direction of the atomizer. The extension portion 22 is connected to the main body portion 21 and is integrally formed on the inner surface of the peripheral side wall 12 .

[0029] Specifically, the liquid storage chamber 1 extends in the axial direction, the peripheral side wall 12 of the liquid storage chamber 1 is parallel to the axial direction of the atomizer, and the bottom wall 11 and the peripheral side wall 12 are arranged vertically. The main body 21 of the heat conductor 2 is integrally formed on the inner surface of the bottom wall 11, and the extension part 22 is integrally formed on the inner surface of the peripheral side wall 12, so that the extension part 22 is parallel to the axial direction of the atomizer, the main body 21 and the extension part 22 are arranged vertically, and the main body 21 and the extension part 22 can be integrally formed. The atomizer core 3 is assembled on the bottom wall 11, so the heat of the atomizer core 3 can be directly or indirectly transferred to the main body 21 through the bottom wall 11, and then transferred to the extension part 22 through the main body 21. Since the extension portion 22 extends in the axial direction of the atomizer, the extension portion 22 can contact the atomized liquid in the liquid storage chamber 1 that is axially away from the main body 21 and the atomizing core 3, and the heat of the extension portion 22 can be used to heat the atomized liquid in the liquid storage chamber 1 that is axially away from the main body 21 and the atomizing core 3, so that the atomized liquid in the liquid storage chamber 1 can be preheated to increase fluidity. It can be understood that as the atomized liquid flows in the direction of the atomizing core 3 and the main body 21, the temperature of the atomized liquid will gradually increase, and the fluidity will gradually increase, so that it can flow to the atomizing core 3 better and meet the atomization requirements of the atomizing core 3 in a timely manner.

[0030] It is worth noting that see Figure 1 and Figure 2, wherein the direction parallel to the X direction of the coordinate system in the figure is the lateral direction, and the direction parallel to the Y direction of the coordinate system in the figure is the axial direction (i.e. the longitudinal direction of the atomizer).

[0031] Furthermore, in the transverse direction of the atomizer, the central axis of the atomizer core 3 and the central axis of the liquid storage chamber 1 are arranged in a deviated manner; the peripheral side wall 12 includes a first sub-side wall 121 and a second sub-side wall 122 that are arranged opposite to each other, wherein in the transverse direction of the atomizer, the first sub-side wall 121 is relatively far away from the atomizer core 3, and the second sub-side wall 122 is relatively close to the atomizer core 3; the first sub-side wall 121 and the second sub-side wall 122 are both provided with an extension portion 22, and the extension dimension of the extension portion 22 of the first sub-side wall 121 is greater than the extension dimension of the extension portion 22 of the second sub-side wall 122.

[0032] Specifically, the peripheral side wall 12 of the liquid storage chamber 1 includes a first sub-side wall 121 and a second sub-side wall 122 that are oppositely arranged. In the transverse direction of the atomizer, the first sub-side wall 121 and the second sub-side wall 122 are at the same distance from the central axis of the atomizer.

[0033] In some embodiments, the inner surface of the first sub-side wall 121 and the inner surface of the second sub-side wall 122 may be integrally formed with an extension portion 22 extending along the axial direction of the atomizer. And in the axial direction of the atomizer, the height of the extension portion 22 of the first sub-side wall 121 is greater than the height of the extension portion 22 of the second sub-side wall 122. In the transverse direction of the atomizer, the central axis of the liquid storage chamber 1 and the central axis of the atomizer core 3 are offset, and the atomizer core 3 is relatively close to the first sub-side wall 121, so that the amount of atomized liquid around the second sub-side wall 122 is relatively large. Therefore, by increasing the extension height of the extension portion 22 of the first sub-side wall 121, the contact area between the heat conductor 2 and the atomized liquid can be further increased, thereby improving the preheating effect of the atomized liquid in the liquid storage chamber 1 that is far away from the atomizer core 3 in the transverse direction of the atomizer.

[0034] In some embodiments, the first sub-side wall 121 may be integrally formed with the extension portion 22 , while the second sub-side wall 122 is not provided with the extension portion 22 , thereby reducing the manufacturing cost and simplifying the manufacturing process.

[0035] Furthermore, the atomizer further includes an air outlet channel 20 disposed on the outer surface of the second sub-side wall 122 , and an atomization channel 10 is defined on one side of the atomization core 3 away from the liquid storage chamber 1 , and the atomization channel 10 is connected to the air outlet channel 20 .

[0036] Specifically, the atomizer further includes a heating element, which is arranged on the side of the atomizer core 3 away from the liquid storage chamber 1, and the atomized liquid in the liquid storage chamber 1 flows to the atomizer core 3 through the avoidance hole 210 and the through hole 110, so that the heating element can heat the atomized liquid on the side of the atomizer core 3 away from the liquid storage chamber 1 to generate an aerosol. In the transverse direction of the atomizer, the atomizer core 3 is relatively close to the second sub-side wall 122, that is, the atomization channel 10 is relatively close to the second sub-side wall 122, and the air outlet channel 20 is arranged on the outer surface of the second sub-side wall 122, so that the paths of the atomization channel 10 and the air outlet channel 20 can be shortened, so that the aerosol formed in the atomization channel 10 can flow to the air outlet channel 20 in time.

[0037] Furthermore, a side of the atomizer core 3 facing the liquid storage chamber 1 is a liquid absorption surface 311 , and the liquid absorption surface 311 at least partially protrudes from the avoidance hole 210 .

[0038] Specifically, the surface of the atomizer core 3 facing the liquid storage chamber 1 is the liquid absorption surface 311, and the atomized liquid in the liquid storage chamber 1 flows to the atomizer core 3 body through the liquid absorption surface 311. The atomizer core 3 is a porous material, such as a porous ceramic. The height of the liquid absorption surface 311 protruding from the avoidance hole 210 is greater than 0mm and less than the height of the liquid storage chamber 1. Exemplarily, the height of the liquid absorption surface 311 protruding from the avoidance hole 210 can be 1mm, 2mm, 3mm, 4mm, etc. In the actual process, the height of the liquid absorption surface 311 protruding from the avoidance hole 210 can be determined according to the height of the liquid storage chamber 1, such as the height of the liquid absorption surface 311 protruding from the avoidance hole 210 can be 1 / 20 of the height of the liquid storage chamber 1, etc. By changing the height of the liquid absorption surface 311 protruding from the avoidance hole 210, the capacity of the atomized liquid stored in the liquid storage chamber 1 can be changed, and the storage capacity of the atomizer core 3 for the atomized liquid can also be changed.

[0039] When the pressure inside the liquid storage chamber 1 decreases as the amount of atomized liquid decreases, the external atmospheric pressure will press the air from the porous gaps of the ceramic into the liquid storage chamber 1, generating bubbles inside the liquid storage chamber 1. Generally, the volume of the bubbles gradually increases. When the buoyancy of the bubbles exceeds the sum of the resistance of the atomized liquid to it and the adsorption force of the liquid absorption surface 311 of the ceramic on it, the bubbles will gradually rise, and the bubbles will leave space for the surrounding atomized liquid to fill. However, the resistance to the bubbles is greater for atomized liquids with higher viscosity. However, in the related art, the surrounding sides of the planar ceramics in the grooves are flat, which will contact with the bubbles, and will produce a greater adsorption force on the bubbles, making it impossible for the bubbles to overcome the resistance of the atomized liquid and the adsorption force of the ceramics, so that the bubbles cannot rise, and the bubbles continue to grow. The space around the ceramics will be occupied by bubbles, completely isolating the path for the atomized liquid to penetrate into the ceramics, and the atomization requirements of the ceramics cannot be met. In the present embodiment, the liquid absorption surface 311 is partially protruded from the avoidance hole 210, so that the liquid absorption surface 311 has only a small contact area with the bubbles generated during the ventilation process, thereby reducing the adsorption force of the ceramic on the bubbles, accelerating the rising of the bubbles, and achieving smooth flow of the atomized liquid to the ceramic, thereby avoiding dry burning of the heating element and the generation of a burnt smell.

[0040] Further, the liquid absorbing surface 311 includes at least one inclined surface inclined toward the liquid storage chamber 1 ; or, the liquid absorbing surface 311 includes a curved surface protruding from the avoidance hole 210 .

[0041] Furthermore, the liquid absorbing surface 311 includes at least two inclined surfaces arranged opposite to each other, and at least the two inclined surfaces extend obliquely from the edge of the liquid absorbing surface 311 toward the center into the liquid storage chamber 1; or, the curved surface includes an arc surface.

[0042] In some embodiments, the liquid suction surface 311 may include an inclined surface. Compared with the planar liquid suction surface 311, by setting the liquid suction surface 311 as an inclined surface inclined toward the liquid storage chamber 1, the adsorption force of the liquid suction surface 311 on the bubbles formed during the ventilation process can be reduced, thereby achieving rapid rise of the bubbles.

[0043] In some embodiments, the liquid absorption surface 311 may include two oppositely disposed inclined surfaces, and the two inclined surfaces may be connected in a < shape, wherein the connection portion faces the liquid storage chamber 1, and the bubbles generated during the ventilation process contact the connection portion between the two inclined surfaces, thereby reducing the contact area between the liquid absorption surface 311 and the bubbles, and further reducing the adsorption force of the liquid absorption surface 311 on the bubbles, thereby achieving rapid rising of the bubbles.

[0044] In some embodiments, the liquid absorption surface 311 may include more than two inclined surfaces, and each inclined surface extends from the edge of the liquid absorption surface 311 toward the center to the liquid storage chamber 1, and the connection is toward the liquid storage chamber 1. Multiple inclined surfaces are connected in a pyramid shape, and the connection is toward the liquid storage chamber 1. The bubbles generated during the ventilation process contact the connection of the multiple inclined surfaces, thereby reducing the contact area between the liquid absorption surface 311 and the bubbles, and further reducing the adsorption force of the liquid absorption surface 311 on the bubbles, thereby achieving rapid rising of the bubbles.

[0045] Furthermore, the inclination angle of the inclined surface is greater than 0° and less than 90°.

[0046] Specifically, the inclination angle of the inclined plane refers to the angular relationship between the plane where the inclined plane is located and the atomizer horizontally, and the inclination angle of the inclined plane can be 1°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 89°, etc. It can be understood that when the liquid suction surface 311 includes two or more inclined planes, the inclination angles of different inclined planes can be the same or different. By changing the inclination angle size of the inclined plane, the contact area of ​​the liquid suction surface 311 to the bubble can be changed, thereby changing the adsorption force of the liquid suction surface 311 to the bubble.

[0047] In some embodiments, the liquid suction surface 311 may include a curved surface. The line connecting the two end points of the curved surface is parallel to the lateral direction of the atomizer, and the highest point of the curved surface faces the liquid storage chamber 1. By setting the liquid suction surface 311 as a curved surface, the bubbles formed during the ventilation process contact the highest point of the curved surface, which can also reduce the contact area between the liquid suction surface 311 and the bubbles, reduce the adsorption force of the liquid suction surface 311 on the bubbles, and achieve rapid rise of the bubbles.

[0048] Furthermore, the angle between the tangent line of the end point of the curved surface and the horizontal direction of the atomizer can be 1°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 90°, etc. By changing the angle between the tangent line of the end point of the curved surface and the horizontal direction of the atomizer, the contact area of ​​the liquid absorption surface 311 on the bubble can be changed, thereby changing the adsorption force of the liquid absorption surface 311 on the bubble.

[0049] In some embodiments, the liquid suction surface 311 may include multiple curved surfaces, each curved surface bends from the edge of the liquid suction surface 311 to the center and extends to the liquid storage chamber 1. The multiple curved surfaces may be connected in an umbrella shape, and the connection is toward the liquid storage chamber 1. The bubbles generated during the ventilation process contact the connection of the multiple curved surfaces, thereby reducing the contact area between the liquid suction surface 311 and the bubbles, and further reducing the adsorption force of the liquid suction surface 311 on the bubbles, thereby achieving rapid rise of the bubbles. Furthermore, by changing the degree of curvature of each curved surface, the contact area of ​​the liquid suction surface 311 on the bubbles can be changed, thereby changing the adsorption force of the liquid suction surface 311 on the bubbles.

[0050] Furthermore, in some embodiments, the atomizer core 3 has a liquid absorption surface 311 facing the liquid storage chamber 1 , and in the axial direction, the liquid absorption surface 311 is flush with an end surface of the avoidance hole 210 close to the liquid storage chamber 1 .

[0051] Specifically, the portion of the atomizer core 3 close to the liquid absorption surface 311 is arranged in the avoidance hole 210, and the liquid absorption surface 311 is flush with the end surface of the avoidance hole 210 close to the liquid storage chamber 1, so that no space for accommodating bubbles can be formed between the avoidance hole 210 and the liquid absorption surface 311, thereby solving the problem of poor liquid supply caused by airway blockage.

[0052] Furthermore, the atomizer core 3 includes a liquid suction portion 31 and an atomization portion 32, part of the liquid suction portion 31 is arranged in the avoidance hole 210 to communicate with the liquid storage chamber 1, and the atomization portion 32 is arranged on the side of the liquid suction portion 31 away from the liquid storage chamber 1, and a liquid gap is formed between the outer wall of the liquid suction portion 31 and the inner wall of the avoidance hole 210; in the axial direction of the atomizer, the projection surface of the atomization portion 32 covers the projection surface of the liquid suction portion 31 and the projection surface of the liquid gap.

[0053] In some specific embodiments, the atomizing core 3 is composed of a liquid suction part 31 and an atomizing part 32. The axial directions of the atomizing part 32 and the liquid suction part 31 are parallel to the axial direction of the atomizer. The side of the liquid suction part 31 facing the liquid storage chamber 1 is a liquid suction surface 311, and the side of the liquid suction part 31 facing away from the liquid storage chamber 1 is connected to the atomizing part 32. A liquid-passing gap is formed between the outer wall of the liquid suction part 31 and the inner wall of the avoidance hole 210. Therefore, in addition to flowing to the atomizing part 32 through the liquid suction part 31, the atomized liquid in the liquid storage chamber 1 can also be stored in the liquid-passing gap, or directly flow to the atomizing part 32 through the liquid-passing gap. A heating element is provided on the side of the atomizing part 32 facing away from the liquid suction part 31, and an atomizing channel 10 is formed on the side of the atomizing part 32 facing away from the liquid suction part 31. Since the axial projection surface of the atomization part 32 covers the axial projection surface of the liquid suction part 31 and the projection surface of the liquid passing gap, the atomization part 32 can block the liquid passing gap. The atomized liquid flowing into the liquid passing gap will pass through the atomization part 32 and be supplied to the heating element for heating and atomization, and will not flow directly to the atomization channel 10, thereby ensuring the sealing of the atomizer and preventing leakage of the atomized liquid.

[0054] Furthermore, the atomizer further includes a sealing member 4 , which is clamped between the outer wall of the atomizing portion 32 and the inner wall of the through hole 110 .

[0055] Specifically, the atomization part 32 is arranged between the inner walls of the through hole 110. During the assembly process, there may be a gap between the outer wall of the atomization part 32 and the inner wall of the through hole 110. By setting a seal 4 between the outer wall of the atomization part 32 and the inner wall of the through hole 110, the sealing of the atomizer can be further ensured, preventing the atomized liquid from leaking from the gap between the outer wall of the atomization part 32 and the inner wall of the through hole 110.

[0056] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0057] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
