[0052] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0053] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device provided in an embodiment of the present application; in this embodiment, an electronic atomization device 100 is provided.

[0055] Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device, such as a microphone, a bracket, etc. The specific structures and functions of these components are the same or similar to those in the prior art. For details, please refer to the prior art and will not be repeated here.

[0056] In one specific embodiment, see Figure 2a and Figure 2b ,in, Figure 2a A schematic diagram of the structure of an atomizer provided in one embodiment of the present application; Figure 2b for Figure 2a Schematic diagram of the local structure at A in the middle; the atomizer 10 includes a bottom plate 11a, an atomizer seat 11b, an atomizer core 12 and a liquid guide component 141b.

[0057] Among them, the bottom plate 11a can be a horizontal panel; the bottom plate 11a has a first surface and a second surface arranged opposite to the first surface; the atomizer seat 11b is covered on the first surface of the bottom plate 11a, and cooperates with the first surface of the bottom plate 11a to form an atomization chamber 15; specifically, the atomizer seat 11b includes a side wall and a top wall, and the side wall and the top wall of the atomizer seat 11b cooperate to form a concave structure, and the atomizer seat 11b with the concave structure cooperates with the first surface of the bottom plate 11a to form the atomization chamber 15; the atomizer core 12 is accommodated in the atomization chamber 15, and is used to heat and atomize the liquid in the atomization chamber 15 when power is turned on; the liquid guide component 141b is used to absorb the liquid on the bottom plate 11a.

[0058] In a specific embodiment, the electronic atomization device 100 is further formed with a liquid storage chamber 16, which is used to store liquid; a lower liquid hole is opened on the top wall of the atomization seat 11b, one end of the lower liquid hole is connected to the liquid storage chamber 16, and the other end is connected to the atomization chamber 15; a plurality of liquid suction holes are formed on the atomization core 12, and one end of the liquid suction hole is connected to the lower liquid hole, and the other end is connected to the atomization chamber 15, so that the liquid in the liquid storage chamber 16 can flow to the surface of the atomization core 12 through the lower liquid hole and the liquid suction hole; specifically, the atomization core 12 is arranged on the liquid guide component 141b, so as to support the atomization core 12 through the liquid guide component 141b; and the side surface of the atomization core 12 away from the liquid guide component 141b is in contact with the top wall of the atomization seat 11b to prevent leakage. In one embodiment, the atomization core 12 can be a porous ceramic, and the micropores of the atomization core 12 form the liquid suction hole.

[0059] In a specific embodiment, the atomizer 10 further includes a heating element 13, which is specifically disposed on a side surface of the atomizer core 12 away from the atomizer seat 11b, and is used to heat and atomize the liquid on the surface of the atomizer core 12 when power is turned on; specifically, the heating element 13 may be a heating film disposed on the surface of the atomizer core 12.

[0060] For details, see Figure 3a to Figure 3c ,in, Figure 3a A schematic diagram of the structure of the atomizer seat provided in the first embodiment of the present application; Figure 3b for Figure 3a A top view of Figure 3c A schematic plan view of a first guide portion and a second guide portion provided in an embodiment of the present application; the liquid guide assembly 141b includes a first guide portion 142 and a second guide portion 143. In an embodiment, the second guide portion 143 is disposed on the first surface of the bottom plate 11a and is perpendicular to the first surface of the bottom plate 11a; the atomizer core 12 is specifically disposed at one end of the second guide portion 143 away from the first guide portion 142.

[0061] A boss 147 is formed on the first surface of the bottom plate 11a, and a plurality of air inlet holes 148 are formed on the boss 147 and penetrate the upper and lower surfaces thereof, and outside air can enter the atomizing chamber 15 from the air inlet holes 148; wherein, by making the end of the air inlet hole 148 facing the atomizing core 12 higher than the first surface of the bottom plate 11a, it is possible to prevent the liquid on the first surface of the bottom plate 11a from leaking from the air inlet hole 148. Specifically, the bottom plate 11a can be elliptical, the boss 147 is specifically formed at the central position of the elliptical bottom plate 11a, and the plurality of air inlet holes 148 are evenly distributed around the air inlet hole 148 with one of the air inlet holes 148 as the center.

[0062] The first guide portion 142 is arranged on the first surface of the bottom plate 11a and cooperates with the first surface of the bottom plate 11a to form at least one first guide channel 151; in a specific embodiment, the first guide portion 142 can be integrally formed with the bottom plate 11a, and it can be specifically dense ceramic; the second guide portion 143 is arranged on the first surface of the bottom plate 11a, and the second guide portion 143 has at least one second guide channel 152, and one end of the second guide channel 152 is connected to the first guide channel 151; so that the liquid on the first surface of the bottom plate 11a is guided to the atomizer core 12 through the first guide channel 151 and the second guide channel 152; specifically, the lateral dimension of the first guide channel 151 gradually decreases along the direction toward the second guide portion 143, so that The capillary force of the first guide channel 151 gradually increases along the direction toward the second guide part 143, so that the gradually increased capillary force is used to absorb and guide the liquid on the first surface of the bottom plate 11a, that is, additional power is provided for the liquid on the surface of the bottom plate 11a to flow back to the second guide part 143, so that the liquid on the first surface of the bottom plate 11a can flow into the first guide channel 151, and flow to the second guide part 143 through the second guide channel 152 connected to the first guide channel 151, so that the second guide part 143 is used to store the liquid accumulated on the first surface of the bottom plate 11a, thereby greatly reducing the probability of the liquid on the first surface of the bottom plate 11a leaking from the air inlet 148 and causing leakage problems.

[0063] In a specific embodiment, the other end of the second guide channel 152 is connected to the atomizer core 12, and the capillary force of the second guide channel 152 is smaller than the capillary force of the atomizer core 12, so that the liquid on the bottom plate 11a is drained to the atomizer core 12 or the liquid storage chamber 16 connected to the atomizer core 12 through the first guide channel 151 and the second guide channel 152, thereby realizing the reflux of the liquid on the bottom plate 11a to improve the liquid utilization rate; compared with the rectangular liquid suction groove in the prior art, not only the probability of leakage is greatly reduced, but also It is possible to utilize the gradually enhanced capillary force of the variable diameter guide groove to absorb and guide the liquid on the surface of the bottom plate 11a, effectively increasing the amount of liquid reflux; it is understandable that the regular non-variable diameter (i.e., the same lateral dimensions) liquid absorption groove does not have a unidirectional flow guiding function, while the variable diameter (i.e., different lateral dimensions) guide channel can provide the liquid with the power to flow from the large-size channel to the small-size channel; and because the small-size guide channel has a more obvious capillary phenomenon, it can make the liquid flow to the guide channel with a smaller lateral dimension, thereby reducing the amount of liquid leakage. Among them, the lateral dimension specifically refers to the relative distance between the two side walls of the guide channel.

[0064] In addition, if there is a large amount of liquid formed by condensation or the like in the second guide channel 152, during the downward flow process, the size of the second guide channel 152 to the first guide channel 151 gradually increases, which can form a certain resistance to the downward flow trend, thereby preventing the liquid from moving toward the first surface of the bottom plate 11a, thereby promoting the liquid to flow toward the atomization core 12.

[0065] For details, see Figure 3a and Figure 3b The first guide channel 151 is a first guide groove formed on the first surface of the bottom plate 11a; of course, in other embodiments, the first guide channel 151 may also be a first guide hole formed on the first surface of the bottom plate 11a; specifically, the top of the first protrusion and the second protrusion are connected, and at this time, the first guide channel 151 is the first guide hole.

[0066] In a specific embodiment, the first guide portion 142 may include a first protrusion and a second protrusion that are spaced apart from each other, and the first protrusion and the second protrusion and the first surface of the bottom plate 11 a define at least one first guide groove.

[0067] In one embodiment, the surface of the first protrusion close to the second protrusion is an inner arc surface, and the surface of the second protrusion close to the first protrusion is an outer arc surface. In this embodiment, the first guide groove formed by the first protrusion and the second protrusion cooperating with the first surface of the bottom plate 11a is arc-shaped.

[0068] In a specific embodiment, the first protrusion includes two arc-shaped protrusions 1421, and the second protrusion is an annular protrusion 1422; the two arc-shaped protrusions 1421 are arranged on both sides of the annular protrusion 1422 and are spaced from the annular protrusion 1422, and one end of each arc-shaped protrusion 1421 abuts against the edge of the second guide portion 143, and the other end extends in a direction away from the second guide portion 143, and the relative distance between the arc-shaped protrusion 1421 and the annular protrusion 1422 gradually decreases in a direction toward the second guide portion 143, so as to cooperate with the first surface of the bottom plate 11a to form two first guide grooves. It can be understood that the relative distance between the arc-shaped protrusion 1421 and the annular protrusion 1422 is the lateral dimension of the first guide groove.

[0069] In one embodiment, the two arc-shaped protrusions 1421 are located on the same arc, and the arc where the two arc-shaped protrusions 1421 are located is eccentrically arranged with the arc where the annular protrusion 1422 is located, that is, the center of the arc where the two arc-shaped protrusions 1421 are located is offset from the center of the arc where the annular protrusion 1422 is located, so that the relative distance between the arc-shaped protrusion 1421 and the annular protrusion 1422 gradually decreases in the direction toward the second guide portion 143.

[0070] In a specific embodiment, the annular protrusion 1422 is in a circular ring shape, and the surface of the annular protrusion 1422 close to the second guide portion 143 has a cut plane, and the vertical distance of the cut plane from the second guide portion 143 is smaller than the lateral dimension of the first guide channel 151 at a position close to the second guide portion 143, so that the lateral dimension of the channel defined by the cut plane and the second guide portion 143 and the first surface of the bottom plate 11a is smaller than the lateral dimension of the first guide channel 151, thereby making the capillary force at this position greater than the capillary force of the first guide channel 151, so as to absorb and guide the liquid in the first guide channel 151, so that the liquid in the first guide channel 151 further flows toward this position to enter other second guide channels 152 corresponding to this position, and flow back to the atomizer core 12.

[0071] It is understood that in this embodiment, see Figure 3c The transverse dimensions of the first guide channel 151 and the second guide channel 152 gradually decrease from position A to position D, that is, L A >L B >L C >L D In this way, the liquid can be collected at position A and driven to flow to position B. After that, part of the liquid flows to position D through the first second guide channel 152 to flow back to the atomizer core 12, while the other part of the liquid flows to other second guide channels 152 through the channel where position C is located, so as to flow back to the atomizer core 12 through a second guide channel different from the first second guide channel 152, thereby realizing the liquid flowing back to the atomizer core 12 from the first surface of the bottom plate 11a.

[0072] Specifically, experimental results show that after liquid is dripped onto the first surface of the bottom plate 11a, the end of the first guide channel 151 away from the second guide portion 143 can guide the liquid into the first guide channel 151, and can flow smoothly to the second guide channel 152 closest to the first guide channel 151. After filling the closest second guide channel 152, the liquid further flows through the channel at position C to the slightly farther second guide channel 152 until all the second guide channels 152 are filled.

In a specific embodiment, one end of the third flow guiding channel 153 is specifically connected to the second flow guiding channel 152 at the edge of the second flow guiding portion 143.

[0083] Specifically, the third guide channel 153 and the second guide channel 152 can both be linear channels, and the third guide channel 153 is vertically arranged with the second guide channel 152; in a specific embodiment, the third guide channel 153 can also be a guide groove or a guide hole, which is not limited in this embodiment.

For details, please refer to the above-mentioned related text records, which will not be repeated here.

[0086] Specifically, in this embodiment, the atomizer core 12 is arranged at one end of the second guide part 143 and the fourth guide part 145 away from the bottom plate 11a, and abuts against the second guide part 143 and the fourth guide part 145, so as to support the atomizer core 12 to a certain extent through the second guide part 143 and the fourth guide part 145, and at the same time, the liquid passing through the second guide part 143 and / or the fourth guide part 145 can flow back to the atomizer core 12; it can be understood that, in other embodiments, the fourth guide channel 154 may not be provided on the fourth guide part 145, and the fourth guide part 145 only supports the atomizer core 12 to a certain extent.

[0087] Furthermore, the liquid guide component 141b further includes a fifth guide portion 146, which is disposed on the first surface of the bottom plate 11a, and the fifth guide portion 146 cooperates with the first surface of the bottom plate 11a to form at least one fifth guide channel 155, one end of the fourth guide channel 154 is connected to the fifth guide channel 155 to communicate with the first surface of the bottom plate 11a, and the capillary force of the fourth guide channel 154 is greater than the capillary force of the fifth guide channel 155, so that the fifth guide portion 146 passes through the capillary force of the fifth guide channel 155.

It is understandable that, in this embodiment, the boss 147 is formed on the base 141a, and a through hole communicating with the air inlet 148 is formed on the base 141a, so that the atomizing chamber 15 is communicated with the outside air.

Compared with the prior art, not only the probability of leakage is greatly reduced, but also the gradually enhanced capillary force of the guide channel is used to absorb and guide the liquid on the surface of the base 141a, thereby effectively improving the reflux amount and reflux efficiency of the liquid.
