In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0048] Please refer to Figures 1-3 The embodiment of the present application provides an atomizer 100 which can be matched with a battery rod to form an electronic atomization device together. The battery rod is provided with a power supply and a control circuit, and the control circuit is used for controlling the power supply to supply power to the atomizer 100.

[0049] The atomizer 100 comprises an oil cup 10 and an atomization assembly 200. The atomization assembly 200 is installed in the lower end of the oil cup 10 and forms a liquid storage cavity 13 with the oil cup 10. The lower end of the oil cup 10 is open, and the upper end is provided with an air inlet 11 for user suction. The inner wall of one end of the oil cup 10 provided with the air inlet 11 is formed with a gas guide pipe 12 extending into the inside of the oil cup 10 at the edge of the air inlet 11. The inside of the gas guide pipe 12 communicates with the air inlet 11. The liquid storage cavity 13 is formed between the gas guide pipe 12 and the inner wall of the oil cup 10 to store atomization liquid. In this embodiment, the gas guide pipe 12 and the oil cup 10 are integrally formed as a whole.

[0050] The inside of the atomization assembly 200 is divided into an atomization cavity 231 and a condensation cavity 415 in the up-down direction. The atomization assembly 200 comprises a heating assembly 30 arranged in the atomization cavity 231. The heating assembly 30 can be arranged vertically, horizontally or obliquely, which is not limited in this embodiment. The heating assembly 30 comprises a liquid guide body 31 fixedly arranged on the inner wall of the atomization cavity 231 and a heating body 32 arranged on one side of the liquid guide body 31 facing the atomization cavity 231. The liquid guide body 31 can absorb the atomization liquid stored in the liquid storage cavity 13 through the liquid inlet channel 222 and guide the atomization liquid to contact the heating body 32. When the heating body 32 is powered and heated, the atomization liquid in contact with the heating body 32 is heated and atomized to generate aerosol for smoking.

[0051] The bottom of the condensation cavity 415 is upwardly convex to form an air inlet pipe 416, and the air inlet pipe 416 has an air inlet hole 412 in communication with the condensation cavity 415; the atomization cavity 231 and the condensation cavity 415 are in communication through a first air passing hole 431, when a user performs suction on the suction port 11, external air enters the condensation cavity 415 from the air inlet hole 412, and then enters the atomization cavity 231 from the first air passing hole 431 to mix with the aerosol generated by the heating body 32, and then is output from the suction port 11 through the air guide pipe 12 and finally is inhaled by the user.

[0052] In the embodiment, the first air passing hole 431 and the air inlet hole 412 are arranged in a staggered manner; in this way, the atomizer 100 of the present application forms a condensation cavity 415 at the bottom of the atomization cavity 231, when the condensate formed in the atomization cavity 231 accumulates, the condensate can flow into the condensation cavity 415 through the first air inlet hole 412, so that the user is not easy to suck the condensate during suction; only when the liquid level of the condensate collected in the condensation cavity 415 is higher than the top end of the air inlet pipe 416, the condensate can flow out of the atomizer 100 from the air inlet hole 412. In theory, as long as the volume of the condensation cavity 415 is large enough, the condensate collected in the condensation cavity 415 can be prevented from flowing out of the atomizer 100; in fact, even if the atomizer 100 works from the beginning to the end of the use of the atomization liquid, the condensate formed will not be too much to fill the condensation cavity 415.

[0053] Since the air inlet hole 412 at the bottom of the atomizer 100 is in communication with the outside, there will be a backflow phenomenon during the user's suction, that is, the aerosol generated in the atomization cavity 231 will also overflow from the first air passing hole 431 into the condensation cavity 415, since the temperature in the condensation cavity 415 is always lower than that in the atomization cavity 231, the aerosol enters the low-temperature condensation cavity 415 from the high-temperature atomization cavity 231, and the aerosol will condense into liquid, that is, most of the aerosol will form condensate in the condensation cavity 415 for storage, and the aerosol overflowing from the air inlet hole 412 to the outside of the atomizer 100 will be very small, thereby reducing the amount of condensate formed by the backflow aerosol in the battery rod.

[0054] In addition, if the atomizer 100 leaks due to poor sealing, the leaked atomization liquid will also fill the condensation cavity 415, and if the leakage is slight, the leaked atomization liquid can be prevented from flowing out of the atomizer 100 from the air inlet hole 412.

[0055] Specifically, the atomizer 100 in the embodiment is separated into the atomizing cavity 231 and the condensing cavity 415 by arranging a partition 43 horizontally inside, and is communicated by arranging a first air inlet hole 412 on the partition 43. Preferably, the air inlet hole 412 is arranged at the center of the bottom of the atomizing assembly 200, and a first air passing hole 431 is arranged eccentrically on the partition 43, so as to ensure that the air inlet hole 412 and the first air passing hole 431 are arranged in a staggered manner, thereby avoiding that the condensing liquid or the atomizing liquid in the atomizing cavity 231 flows out of the atomizer 100 directly from the air inlet hole 412 when the condensing liquid or the atomizing liquid enters the condensing cavity 415 through the first air passing hole 431.

[0056] The structure of the atomizing assembly 200 in the embodiment will be described in detail below in combination with the accompanying drawings. Figures 4 to 11 The atomizing assembly 200 includes a top assembly 20, a heating assembly 30, and a bottom assembly 40. It should be understood that the atomizer 100 in the embodiment is not limited to the structure of the atomizing assembly 200 shown in the drawings. Figures 4 to 11 The atomizing assembly 200 includes a top assembly 20, a heating assembly 30, and a bottom assembly 40. It should be understood that the atomizer 100 in the embodiment is not limited to the structure of the atomizing assembly 200 shown in the drawings.

[0057] The top assembly 20 includes a sealing member 22, a support 21, and an air passage member 23. The sealing member 22 is sleeved on the top end of the support 21 and is sealingly connected with the inner wall of the oil cup 10. One side of the support 21 is recessed to form a receiving space 211 (as shown in Figs. 2 and 3) in which the heating assembly 30 is arranged. Figure 7 and Figure 8 The heating assembly 30 includes an oil guiding body 31 arranged vertically on one side of the receiving space 211 and a heating body 32 arranged on one side of the oil guiding body 31. The oil guiding body 31 is a flat oil absorbing cotton. One side of the oil guiding body 31 is an oil absorbing surface, and the other side opposite to the oil absorbing surface is an atomizing surface. The heating body 32 is arranged on the atomizing surface of the oil guiding body 31. The atomizing amount of the oil absorbing cotton is large, the experience of smoking is good, and the atomizing liquid has a high degree of flavor recovery. In the embodiment, the oil guiding body 31 is perpendicular to the bottom surface of the atomizing assembly 200. In actual application, the oil guiding body 31 can also be arranged obliquely. Preferably, the angle between the oil guiding body 31 and the bottom surface of the atomizing assembly 200 is in the range of 60-120°. It should be understood that the bottom surface of the atomizing assembly 200 is a plane perpendicular to the central axis of the atomizer 100.

[0058] The bottom assembly 40 comprises a base 41 fixed to the bottom end of the bracket 21, two electrodes 42 arranged in the base 41 from bottom to top, and the above-mentioned partition 43, the top surface of the base 41 is recessed to form a receiving space, the partition 43 is sleeved and fixed to the top end of the base 41 and covers the receiving space to form a condensation cavity 415, and an air inlet pipe 416 is integrally formed in the receiving space of the base 41; the upper ends of the two electrodes 42 extend into the receiving space 211 in sequence through the base 41 and the partition 43, so that the heating body 32 is clamped between the two electrodes 42 and the oil guide body 31 in the horizontal direction, and the two ends of the heating body 32 are electrically connected with the two electrodes 42 respectively; the air channel member 23 is preferably made of silica gel material, at least part of which is sealed and mounted in the receiving space 211, and forms an atomization cavity 231 with the heating assembly 30, the lower end of the atomization cavity 231 is covered by the partition 43 and communicates with the condensation cavity 415 in the base 41 through the first air passing hole 412, and the upper end communicates with the air guide pipe 12. The material of the air channel member 24 can also be plastic, hardware or other materials, and the specific material can be selected according to the actual situation, and the embodiment does not limit this.

[0059] The side wall of the sealing member 22 is provided with a liquid inlet channel, and the liquid inlet channel and the inner wall of the oil cup 10 jointly form a liquid inlet channel 222, the upper end of the liquid inlet channel 222 communicates with the liquid storage cavity 13, the other side of the bracket 21 relative to the receiving space 211 is provided with a liquid inlet 212, the liquid inlet 212 communicates with the lower end of the liquid inlet channel 222 and penetrates through the receiving space 211, and the liquid absorption surface of the oil guide body 31 covers the liquid inlet 212, so that the atomized liquid in the liquid storage cavity 13 can be guided into the oil guide body 31 through the liquid inlet channel 222 and the liquid inlet 212, the oil guide body 31 conducts the absorbed atomized liquid to the atomization surface and contacts the heating body 32, and when the heating body 32 is electrified and heated, the contacted atomized liquid is heated and atomized, so that the aerosol for smoking is generated in the atomization cavity 231.

[0060] Optionally, the side wall of the bracket 21 corresponding to the position of the liquid inlet channel of the sealing member 22 can also be provided with a notch communicating with the liquid inlet 212, and the upper end of the notch extends out of the top surface of the bracket 21, so that the notch, the liquid inlet channel and the inner wall of the oil cup 10 jointly form the liquid inlet channel 222.

[0061] Preferably, in order to ensure the liquid inlet speed and avoid the insufficient oil pouring speed of the oil guide body 31 to cause the dry burning and core burning of the heating body 32, the width of the liquid inlet channel 222 is between 0.8-2mm, the length is between 2-8mm, and the cross-sectional area is between 1.6-15mm 2 .

[0062] The heating body 32 is a metal sheet formed by etching a conductive metal, for example, made of nickel-chromium, iron-chromium-aluminum, or stainless steel, and includes two conductive parts 321 and a heating part 322 connected in series between the two conductive parts 321. The resistance of the conductive part 321 is much smaller than that of the heating part 322, so that when the heating body 32 is powered to generate heat, the conductive part 321 only generates a small amount of heat, so that the heat is concentrated in the area of the heating part 322 to ensure the atomization effect. The shape of the heating part 322 is not particularly limited in this embodiment, for example, it can be grid-shaped, striped, S-shaped, polyline-shaped, wavy, zigzag-shaped, spiral-shaped, circular, or rectangular, as long as it can achieve planar heating.

[0063] The two conductive parts 321 are respectively welded and fixed on the same side of the two electrodes 42, as shown in Figure 6 When assembling, the oil guide body 31 can be installed into the accommodation space 211 first, and then the bottom assembly 40 with the heating body 32 welded is installed and fixed on the bracket 21 in the horizontal direction, so that the heating body 32 is pressed on the atomization surface of the oil guide body 31, as shown in Figure 8 Then the air passage 23 is installed and sealed into the accommodation space 211, so as to form the whole atomization assembly 200, as shown in Figure 9 and Figure 10 Finally, the whole atomization assembly 200 is inserted and installed into the open end 14 of the oil cup 10 to complete the assembly of the whole atomizer 100. In this structure, each component is assembled in a vertical or horizontal stacking manner, without the need to bend and wind the heating body 32, which solves the problem that the robot cannot easily operate due to the softness of the oil guide body 31 and the heating body 32, and realizes automatic and batch assembly, improves production efficiency, and reduces cost.

[0064] Of course, in other embodiments, the oil guide body 31 can also be a porous ceramic body, and at this time the heating body 32 can be embedded or brushed on the atomization surface of the oil guide body 31, so that the oil guide body 31 and the heating body 32 form a whole, and when assembling, the heating assembly 30 with the whole structure is installed into the accommodation space 211, and then the bottom assembly 40 is fixed in the horizontal direction to make the upper ends of the two electrodes 42 abut or be welded and fixed on the conductive parts 321 at both ends of the heating body 32, so as to realize the electrical connection between the heating body 32 and the two electrodes 42. This structure can also realize automatic and batch assembly.

[0065] In the present embodiment, the top end of the support 21 is provided with an air outlet hole 213 communicating with the atomization cavity 231 and an annular groove 217 concentric with the air outlet hole 213, and the sealing member 22 is provided with a sleeve joint portion 223 having a sleeve joint hole 224, the lower end of the sleeve joint portion 223 being sleeved in the annular groove 217 so that the sleeve joint hole 224 communicates with the air outlet hole 213. When the atomization assembly 200 is integrally inserted into the open end 14 of the oil cup 10, the lower end of the air guide pipe 12 is inserted into the sleeve joint hole 224 and sealingly connected with the inner wall of the sleeve joint hole 224, thereby avoiding the leakage of the atomized liquid from the gap between the air guide pipe 12 and the sleeve joint hole 224. In this way, the air guide pipe 12 communicates with the atomization cavity 231 through the air outlet hole 213. When the user sucks the suction port 11, external air can enter the atomization cavity 231 through the condensation cavity 415 and mix with the aerosol generated by the heating of the heating body 32, and then be output through the air outlet hole 213, the air guide pipe 12 and the suction port 11 for the user to smoke.

[0066] It should be noted that the bottom end of the sealing member 22 is provided with a plurality of first annular protrusions 221, and the liquid inlet channel is located above the plurality of first annular protrusions 221. When the atomization assembly 200 is integrally inserted into the open end 14 of the oil cup 10, the plurality of first annular protrusions 221 elastically abut against the inner wall of the oil cup 10, thereby achieving the sealing connection between the sealing member 22 and the inner wall of the oil cup 10 to ensure the sealing of the liquid storage cavity 13, so that the atomized liquid in the liquid storage cavity 13 can only flow out from the liquid inlet 212 to the oil guide body 31, avoiding the occurrence of liquid leakage.

[0067] When the atomizer 100 is working, the atomized liquid in the liquid storage cavity 13 continuously flows into the oil guide body 31 and is heated by the heating body 32 to form an aerosol. As the atomized liquid in the liquid storage cavity 13 decreases, the internal pressure gradually decreases, and finally the atomized liquid cannot flow into the oil guide body 31 smoothly. In order to solve the problem of the pressure in the liquid storage cavity 13, the present embodiment is provided with a gas return groove 214 on the side where the support 21 and the oil guide body 31 are attached, and the gas return groove 214 and the oil guide body 31 together form a gas return channel, one end of the gas return channel communicating with the liquid inlet 212 and the other end communicating with the atomization cavity 231. Preferably, the cross-sectional area of the gas return channel is 0.1-0.2 mm 2 ; in this way, when the user sucks, the atomized liquid in the liquid storage cavity 13 is absorbed by the heating assembly 30 and heated to form an aerosol, and the external air mixes with the aerosol and is smoked by the user at the same time. Part of the gas can enter the liquid storage cavity 13 from the formed gas return channel through the liquid inlet 212 and the liquid inlet channel 222, so as to balance the pressure in the liquid storage cavity 13 and avoid the situation of poor oil guiding.

[0068] In one embodiment, as Figure 7 andFigure 8 As shown, the bracket 21 is recessed to form vertical positioning clamping grooves 215 on both sides of the accommodation space 211, the two positioning clamping grooves 215 extend through the bottom of the bracket 21, and the positioning clamping grooves 215 are provided with positioning blocks 216; the base 41 is provided with two positioning columns 413 extending upward at both ends along the long axis direction, and the two positioning columns 413 are provided with clamping holes 414 matched with the positioning blocks 216; the two positioning columns 413 are buckled in the two positioning clamping grooves 215 along the horizontal direction, and the positioning blocks 216 are clamped into the clamping holes 414 to fix the base 41 and the bracket 21 vertically, so that the oil guide body 31 and the heating body 32 are clamped and fixed between the two electrodes 42 and one side of the accommodation space 211, and automatic assembly can be facilitated.

[0069] Specifically, the partition piece 43 is a flat plate structure made of silica gel or rubber, when the bottom assembly 40 is buckled and installed on the bracket 21 along the horizontal direction, the partition piece 43 is clamped between the bracket 21 and the base 41 upward and downward, and the upper and lower ends of the partition piece 43 are elastically abutted on the bracket 21 and the base 41 respectively, so that the bracket 21 and the base 41 are fixedly connected in the upward and downward directions by the abutting force of the partition piece 43, and the subsequent installation of the airway piece 23 and the overall assembly of the atomization assembly 200 into the oil cup 10 can be facilitated, without using other fasteners to connect and fix the bracket 21 and the base 41, so that automatic assembly can be easily realized.

[0070] Preferably, the peripheral wall of the partition piece 43 is provided with a plurality of second annular protrusions 433, when the atomization assembly 200 is assembled into the opening end 14 of the oil cup 10, the plurality of second annular protrusions on the partition piece 43 are elastically abutted on the inner wall of the oil cup 10, further ensuring the sealing performance between the atomization assembly 200 and the oil cup 10.

[0071] It should be noted that the cross section of the oil cup 10 and the atomization assembly 200 is substantially oval, the base 41 has two installation passages 411 extending through the upper and lower ends thereof, the two installation passages 411 are symmetrically located at both ends of the base 41 along the long axis direction, the partition piece 43 is provided with first through holes 434 at positions corresponding to the two installation passages 411 at both ends thereof, the two electrodes 42 are inserted into the two installation passages 411 from the bottom to the top of the base 41, the upper ends of the two electrodes 42 are respectively provided with heating bodies 32, and the two end conductive parts 321 of the heating bodies 32 are respectively welded and fixed to one side of the upper end of the two electrodes 42. In addition, the partition piece 43 is provided with second through holes 435 at positions corresponding to the two positioning columns 413 at both ends thereof along the long axis direction, when the partition piece 43 is sleeved to the top end of the base 41, the upper ends of the two positioning columns 413 are respectively inserted into the two second through holes 435.

[0072] Specifically, in combination with Figure 11As shown, the air passage 23 protrudes from the side facing the heating element 30, forming two abutment portions 233. These two abutment portions 233 abut against the oil guide body 31 and press against the conductive portions 321 at both ends of the heating element 32, thereby making the heating element 32 more tightly attached to the atomizing surface of the oil guide body 31. The abutment portions 233 acting on the oil guide body 31 restrict the position of the air passage 23, facilitating automated assembly. Preferably, the two abutment portions 233 are located inside the two electrodes 42, thus using the air passage 23 and the heating element 30 to jointly form the atomizing chamber 231, and placing the two electrodes 42 outside the atomizing chamber 231 to prevent the generated aerosol from forming condensate on the electrodes 42.

[0073] Furthermore, a second vent hole 432 can be provided on the separator 43. The first vent hole 431 and the second vent hole 432 are symmetrically arranged at both ends of the separator 43 along its short axis. After the atomizing assembly 200 is assembled, the second vent hole 432 is blocked by the bracket 21 and becomes inactive. Only the first vent hole 431 connects the condensing chamber 415 and the atomizing chamber 231. This allows the bottom assembly 40 to be assembled even after rotating 180° along its central axis. In this case, the first vent hole 431 is blocked by the bracket 21 and becomes inactive. Only the second vent hole 432 connects the condensing chamber 415 and the atomizing chamber 231. In other words, it is not necessary to align the vent hole of the bottom assembly 40 with the atomizing chamber 231 on the air passage 23, making automated assembly more convenient. Preferably, in this embodiment, there are two first air passages 431 and two second air passages 432. Of course, there can also be one, three or more. The air inlet 412 is staggered with each of the first air passages 431 and the second air passages 432.

[0074] The specific assembly steps of the atomizer 100 of the present invention are as follows:

[0075] like Figure 4 As shown, two electrodes 42 are respectively installed into the two mounting channels 411 of the base 41. Then, the separator 43 is fitted onto the top of the base 41 so that the upper ends of the two electrodes 42 pass through the two first through holes 434 on the separator 43. The electrodes 42 are interference-fitted with the inner walls of the first through holes 434, thereby fixing the base 41, the separator 43, and the two electrodes 42 together to form the bottom assembly 40. Figure 5 As shown.

[0076] like Figure 6 As shown, the two conductive parts 321 of the heating element 32 are welded and fixed to the same side of the two electrodes 42, and the oil guide body 31 is installed in the receiving space 211 of the bracket 21, and the oil guide body 31 is tightly attached to the side surface with the liquid inlet 212, and the edge of the oil guide body 31 is interference-fitted with the inner wall of the receiving space 211.

[0077] likeFigure 8 As shown, the bottom component 40 is fastened to the bracket 21 in a horizontal direction, so that the heating element 32 and the two electrodes 42 are pressed tightly onto the oil guide body 31.

[0078] like Figure 9 As shown, the air passage component 23 is assembled into the receiving space 211 of the bracket 21. At this time, an atomizing chamber 231 is formed between the heating component 30 and the air passage component 23. The first air passage 431 or the second air passage 432 on the separator 43 is connected to the atomizing chamber 231.

[0079] like Figure 12 and Figure 13 As shown, the sealing element 22 is fitted onto the top of the bracket 21, thereby completing the assembly of the atomizing component 200 and forming a whole.

[0080] Install the atomizing component 200 into the open end 14 of the oil cup 10. At this time, the sealing component 22 and the separator 43 are sealed to the inner wall of the oil cup 10, and the base 41 is snapped to the oil cup 10 to complete the assembly of the atomizer 100.
