Description

Technical Field

[0001] The present invention belongs to the technical field of atomization, and in particular relates to a heating atomization component, a heating atomization device and an electronic atomizer thereof. Background Art

[0002] Electronic atomization technology is a technology that heats a liquid to the boiling point through electricity to evaporate and generate atomized vapor. Currently, it is mostly used in the field of electronic cigarettes. With the innovative development of atomization technology, electronic atomization technology is also used in more other fields, such as beauty, medical and other fields. Due to the different concentrations of the atomized liquid, the viscosity difference is large, which will cause the flow velocity of the atomized liquid in the liquid guiding material to be different, so that the speed of the liquid reaching the heating element has a large difference. Therefore, it is necessary to innovate in the structure of the heating atomization component so that when the atomized liquid is relatively thick, the liquid can be quickly conducted to the atomization area of the heating atomization component. According to the kinematic viscosity of the test liquid at different temperatures, it is known that high temperature can reduce the kinematic viscosity of the liquid, thereby accelerating the flow velocity of the liquid. Taking the viscosity of an oily substance obtained by mixing propylene glycol and glycerol in a ratio of 5:5 at different temperatures as an example, it is found that when the temperature is 0°C, the viscosity is very high, and when the temperature rises to 100°C, the viscosity is relatively low; different liquid viscosities may cause the following problems: too high viscosity may cause insufficient liquid supply on the atomization surface of the liquid guide, resulting in a burnt core; there is a large difference in the viscosities of the liquids in the liquid, the liquid with a large viscosity has a slow liquid supply, and the liquid with a small viscosity has a fast liquid supply, resulting in poor overall atomization effect.

The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0058] Embodiment 1, as Figure 1-13As shown in the figure, a heating and atomizing component 10 includes a liquid guide 1 and a heating element 2. At least one liquid inlet surface 11 is provided on the side wall of the liquid guide 1. The liquid inlet surface 11 can be set to one or multiple. Liquid enters the liquid guide 1 through the liquid inlet surface 11. The heating element 2 includes an embedded part 21 and an atomizing part 22 which are of an integral structure or fixedly connected together. That is, the embedded part 21 and the atomizing part 22 can be of an integral structure and formed integrally during production to reduce the assembly steps. The embedded part 21 and the atomizing part 22 can also be separate structures and are fixedly connected together. The embedded part 21 is buried in the liquid guide 1, and the atomizing part 22 is attached or embedded on the atomizing surface 12 provided at the bottom and / or side wall of the liquid guide 1. During manufacturing, the heating element 2 is placed and fixed in a mold, and liquid guide slurry is poured into the mold to form an integrated structure of the heating element 2 and the liquid guide 1, so that the embedded part 21 of the heating element 2 is buried in the liquid guide 1, and the atomizing part 22 is attached or embedded at the bottom or / and side wall of the liquid guide 1. The heating and atomizing component 10 is made into a columnar structure. Compared with other bowl-shaped and tubular structures, the columnar structure has high strength and is not easily damaged during assembly and use. The embedded part 21 is arranged corresponding to the liquid inlet surface 11 to preheat the liquid around the liquid inlet surface 11, so that the viscosity of the liquid with a relatively high viscosity is reduced, the flow rate of the liquid in the liquid guide 1 is accelerated, and the liquid is quickly replenished to the atomizing surface 12. The atomizing part 22 is attached or embedded on the atomizing surface 12 provided at the bottom and / or side wall of the liquid guide 1, that is, the atomizing part 22 is attached or embedded at the bottom of the liquid guide 1, can also be attached or embedded on the side wall of the liquid guide 1, or can be attached or embedded on the bottom and side wall of the liquid guide 1 at the same time, and an atomizing surface 12 is formed on the corresponding bottom surface of the liquid guide 1 and / or the side wall surface of the liquid guide 1.

[0059] The implementation process of the heating and atomizing component 10: During operation, liquid enters the liquid guide 1 through the liquid inlet surface 11, and the liquid is conducted towards the atomizing surface 12. When the liquid reaches the embedded part 21 of the heating element 2, the embedded part 21 of the heating element 2 emits heat to preheat the liquid around the liquid inlet surface 11 of the liquid guide 1, so that the viscosity of the liquid with a relatively high viscosity is reduced, the flow rate of the liquid is accelerated, and the liquid is quickly replenished to the atomizing surface 12. At the same time, the atomizing part 22 generates heat to atomize the liquid at the atomizing surface 12 into atomized steam, and the atomized steam is mixed with the air entering the heating and atomizing component 10 to form an aerosol. By providing the embedded part 21 and the atomizing part 22, and the atomizing part 22 is arranged corresponding to the liquid inlet surface 11, the liquid supply rate of the heating and atomizing component 10 is increased, thereby improving the atomization efficiency and avoiding the phenomenon of core coking caused by insufficient liquid supply.

[0060] Further, as Figure 3-8 shown, at least one liquid inlet hole 13 is transversely opened on the side wall of the liquid guide 1, and the inner wall surface of the liquid inlet hole 13, especially the bottom surface, forms the liquid inlet surface 11. As Figure 12-13As shown in the figure, at least one liquid inlet hole 13 is longitudinally formed on the side wall of the liquid guide body 1. The side wall surface of the liquid inlet hole 13 is the liquid inlet surface 11. The longitudinally arranged liquid inlet hole 13 can be arranged inside the embedded part 21 or outside the embedded part 21 and is arranged close to the embedded part 21. The liquid inlet hole 13 can be one or multiple. Multiple liquid inlet holes 13 are arranged at intervals, and liquid can be introduced simultaneously at different positions, which speeds up the liquid inlet speed. The interval arrangement is conducive to the uniform entry of the liquid into the liquid guide body 1. The aperture and shape of the liquid inlet hole 13 are not limited. The liquid inlet surface 11 is correspondingly arranged with the embedded part 21. The arrangement of the liquid inlet hole 13 speeds up the rate of the liquid entering the liquid guide body 1 and also increases the surface area of the liquid inlet surface 11, so that the liquid has a larger contact area with the liquid guide body 1. At the same time, the liquid inlet surface 11 is correspondingly arranged with the embedded part 21, which can be understood as that the longitudinally arranged liquid inlet hole 13 as a whole faces the embedded part 21, and the longitudinally arranged liquid inlet hole 13 as a whole is parallel or obliquely arranged with respect to the embedded part 21, shortening the distance from the liquid inlet surface 11 to the embedded part 21, and the preheating effect of the liquid is better. At the same time, the arrangement of the liquid inlet hole 13 is equivalent to forming a small liquid storage bin in the liquid guide body 1, which speeds up the liquid inlet rate.

[0061] The atomization surface 12 of the liquid guide body 1 is a plane, a curved surface or a combination of at least two of them, that is, the atomization surface 12 can be a plane and a combination of multiple planes, or a curved surface and a combination of multiple curved surfaces. Of course, it can also be a combination of a plane and a curved surface. Correspondingly, the shape of the heating element 2 matches the atomization surface 12. It can be understood that, as Figure 10 shown in the figure, when the atomization surface 12 is a plane, the atomization part 22 of the heating element 2 is a plane structure matching the plane atomization surface 12, so that the atomization part 22 can be well attached or embedded on the atomization surface 12, avoiding poor contact between the heating element 2 and the liquid guide body 1; as Figure 11 shown in the figure, when the atomization surface 12 is a curved surface, the atomization part 22 of the heating element 2 is a curved surface structure matching the curved surface atomization surface 12. At this time, the heating element 2 can be a spiral structure, a cylindrical structure or an elliptical cylindrical structure, so that the atomization part 22 can be well attached or embedded on the atomization surface 12, avoiding poor contact between the heating element 2 and the liquid guide body 1; when the atomization surface 12 is a combined shape of a plane and a curved surface, the atomization part 22 of the heating element 2 is a structure combining a plane and a curved surface matching the atomization surface 12; the shape of the heating element 2 matching the atomization surface 12 enables the atomization part 22 to be well embedded or attached on the atomization surface 12, avoiding poor contact between the heating element 2 and the atomization surface 12 and affecting the atomization effect.

[0062] The atomization surface 12 of the liquid guide 1 can be provided with one or multiple; in a specific embodiment, one atomization surface 12 is provided and is arranged on the side wall of the liquid guide 1, and the atomization surface 12 arranged on the side wall of the liquid guide 1 is far from the liquid inlet hole 13 arranged on the side wall of the liquid guide 1. It can be understood that correspondingly, one atomization part 22 of the heating element 2 is provided, and this one atomization part 22 is attached or embedded on the side wall of the liquid guide 1 to form the atomization surface 12. The atomization surface 12 being far from the liquid inlet hole 13 arranged on the side wall of the liquid guide 1 means that in the liquid guide 1 with a polygonal structure, the atomization surface 12 and the liquid inlet surface 11 are on different side walls of the liquid guide 1. In the liquid guide 1 with a curved surface structure, there is a certain distance between the two, which is beneficial to controlling atomization; in another specific embodiment, at least two atomization surfaces 12 are arranged at intervals, and all the atomization surfaces 12 are at least arranged at intervals on the side wall of the liquid guide 1, and are arranged staggeredly with the liquid inlet hole 13 arranged on the side wall of the liquid guide 1, or are concentrated and arranged away from each other. It can be understood that correspondingly, at least two atomization parts 22 of the heating element 2 are provided. At least two atomization parts 22 are all attached or embedded on the side wall of the liquid guide 1, and at least two atomization parts 22 are arranged at intervals to form at least two atomization surfaces 12. At least two atomization parts 22 are arranged in parallel or in series. The atomization part 22 and the liquid inlet hole 13 are arranged staggeredly, or the atomization part 22 is arranged away from the liquid inlet surface 11. The so-called concentrated and arranged away from each other here is relative to the staggered arrangement, that is, there is no liquid inlet hole 13 with a very short distance between multiple atomization parts 22. In another specific embodiment, as Figure 3-5 shown, the atomization surface 12 is arranged on the bottom surface of the liquid guide 1, and the corresponding atomization part 22 of the heating element 2 is attached or embedded at the bottom of the liquid guide 1; in another specific embodiment, the atomization part 22 arranged on the bottom of the liquid guide 1 extends towards the side wall of the liquid guide 1, as Figure 6 shown, and can also extend to all the side walls of the liquid guide 1, as Figure 7-9 shown, the atomization part 22 can extend to a part of the side wall of the liquid guide 1, and the extended part of the atomization part 22 forms an atomization surface 12 on the corresponding side wall of the liquid guide 1, that is, the atomization surface 12 and the extended part of the atomization part 22 extend to a part or all of the side wall of the liquid guide 1 to form a semi-surrounding structure of the atomization surface 12 and the atomization part 22.

[0063] The heating element 2 includes a heating circuit 23 and an electrode connecting member 24 connected to the heating circuit 23. The electrode connecting member 24 is connected to an electrode to supply power to the heating circuit 23. The heating circuit 23 generates heat to preheat the liquid in the liquid guide 1 and atomize the liquid on the atomizing surface 12 of the liquid guide 1. Part of the heating circuit 23 is embedded in the liquid guide 1 to form an embedded part 21. The embedded part 21 generates heat to preheat the liquid around the liquid inlet surface 11, reduce its viscosity, and accelerate its flow rate. Part of the heating circuit 23 can be embedded or attached to the side wall surface of the liquid guide 1 to form an atomizing part 22. Part of the heating circuit 23 can also be embedded or attached to the bottom surface of the liquid guide 1 to form an atomizing part 22. Part of the heating circuit 23 can also be embedded or attached to both the bottom surface and the side wall surface of the liquid guide 1 to form an atomizing part 22. The atomizing part 22 generates heat to atomize the liquid on the atomizing surface 12 to form atomized steam.

[0064] Further, preferably, at least one longitudinally penetrating notch 14 is provided on the side wall of the liquid guide 1. The notch 14 can be provided with one or multiple notches. The multiple notches 14 are arranged at intervals. The notch 14 communicates with the bottom of the liquid guide 1 to the top of the liquid guide 1 to form an atomizing gas channel. That is, the corresponding atomizing gas channel can be formed with one or multiple channels. It can be understood that the atomizing gas channel extends from the bottom of the liquid guide 1 to the top. The atomized steam formed on the atomizing surface 12 flows out of the heating and atomizing assembly 10 through the atomizing gas channel. Further, at least the atomizing part 22 of the heating element 2 is attached in the notch 14, that is, at least part of the atomizing part 22 is attached or embedded on the surface of the notch 14. The corresponding surface of the notch 14 forms the atomizing surface 12. The atomized steam formed on the atomizing surface 12 flows out along the atomizing gas channel.

[0065] Example 2-1, such as Figure 14-16As shown, a heating atomization device 50 includes a seal 20, a base 30, and the heating atomization component 10 in Embodiment 1 disposed between the base 30 and the seal 20. The base 30 and the seal 20 cooperate to seal the heating atomization component 10 to prevent liquid leakage. An air inlet 31 is provided on the base 30, and the air inlet 31 communicates with the atomization surface 12 of the heating atomization component 10. Air enters from the air inlet 31 of the base 30, flows to the atomization surface 12 of the heating atomization component 10, and forms an aerosol with the atomized steam formed at the atomization surface 12. The heating atomization component 10 is embedded in the seal 20. An inlet port 201 and a hollow structure air guide nozzle 202 are provided at the top of the seal 20. The inlet port 201 communicates with the liquid inlet surface 11 of the liquid guide 1. Liquid enters from the inlet port 201 of the seal 20, flows to the liquid inlet surface 11 of the liquid guide 1, is guided to the atomization surface 12 of the liquid guide 1, and is atomized by the heating element 2 at the atomization surface 12 to form atomized steam. The atomized steam forms an aerosol with air. The air guide nozzle 202 communicates with the atomization surface 12 of the liquid guide 1. The aerosol formed at the atomization surface 12 flows to the air guide nozzle 202 and flows out of the heating atomization device 50. The seal 20 and the liquid guide 1 cooperate to form at least one atomization chamber 3. At least one longitudinally penetrating notch 14 is provided on the side wall of the liquid guide 1. The notch 14 and the seal 20 cooperate to form the atomization chamber 3. The atomized steam formed at the atomization surface 12 accumulates in the atomization chamber 3, making the atomized steam flowing out of the atomization chamber 3 extremely rich. A convex portion 15 is provided at the top side end of the liquid guide 1, and a plug-in portion matching the convex portion 15 is provided on the seal 20. The convex portion 15 and the plug-in portion of the seal 20 are tightly fitted and plugged to form a seal between the two.

[0066] The implementation process of the heating atomization device 50: During operation, air enters the heating atomization component 10 from the air inlet 31 of the base 30, and liquid enters from the inlet port 201 of the seal 20. The liquid flows to the liquid inlet surface 11 of the heating atomization component 10 and is preheated by the embedded portion 21 at the liquid inlet surface 11. The liquid is guided to the atomization surface 12 and is atomized by the atomization portion 22 at the atomization surface 12 to form atomized steam, which is mixed with the incoming air to form an aerosol. The aerosol accumulates in the atomization chamber 3 to form a rich aerosol, and then flows out through the air guide nozzle 202 of the seal 20.

[0067] The remaining parts of the heating atomization device 50 adopt the prior art and will not be elaborated here.

When the electronic atomizer works, the liquid storage chamber 70 supplies liquid to the heating and atomizing device 50. The heating element 2 of the heating and atomizing device 50 generates heat to atomize the liquid into atomized steam. The atomized steam flows to the air guide pipe 80 and flows out of the atomizer housing 60.

[0073] The rest of the electronic atomizer adopts the existing technology and will not be elaborated here.
