[0030] In order to make the technical personnel in the art better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0031] The present application provides an atomizer, as shown in Figure 1 and Figure 2 The atomizer comprises a shell 1, an airway tube 2 and an atomizing core 3; the shell 1 is provided with an air outlet 11 and an opening 12 at two ends respectively, the airway tube 2 is connected with the shell 1 and communicates with the air outlet 11, the shell 1 is provided with a storage bin 13 inside, the atomizing core 3 is arranged at the opening 12 and connected with the airway tube 2, the atomizing core 3 is provided with a flow guide channel 4, the flow guide channel 4 comprises a micro groove 41 with capillary action, the port of the micro groove 41 communicates with the storage bin 13, and the flow guide channel 4 is provided with a plurality of micro holes 5 communicating with the airway tube 2 and the opening 12.

[0032] The working principle of the atomizer provided in the embodiments of the present application is as follows: the atomizing core 3 in the present application absorbs aerosol substrate through capillary principle, specifically, the storage bin 13 stores aerosol substrate, the port of the micro groove 41 is in communication with the storage bin 13, the aerosol substrate is a liquid for soaking, and the micro groove 41 is equivalent to a capillary tube inserted into the aerosol substrate, the attraction of the liquid surface of the aerosol substrate to the solid surface of the inner wall of the micro groove 41 causes the aerosol substrate to enter the flow guide channel 4 along the inner wall of the micro groove 41, the port of the micro hole 5 is in communication with the flow guide channel 4, so when the aerosol substrate passes through the micro hole 5, the attraction of the liquid surface of the aerosol substrate to the solid surface of the inner wall of the micro hole 5 causes the aerosol substrate to flow along the inner wall of the micro hole 5 and not to flow out of the micro hole 5, the aerosol substrate continues to flow along the inner wall of the micro groove 41, and when the flow guide channel 4 and the plurality of micro holes 5 have all absorbed the aerosol substrate, the micro groove 41 no longer guides the aerosol substrate, and the atomizing core 3 completes the absorption of the aerosol substrate.

[0033] When at rest (i.e., when the user does not start to smoke), the atomizing core 3 has absorbed the aerosol substrate through the capillary principle as described above; when the user smokes, the gas outlet 11, the airway tube 2 and the micro hole 5 form a gas passage, the gas enters the atomizing core 3 from the micro hole 5, causing the aerosol substrate to be dispersed into fine particles, realizing primary atomization, the fine aerosol substrate particles come to the atomizing core 3 along with the airflow, the atomizing core 3 atomizes the fine aerosol substrate particles into aerosol after being powered on, realizing secondary atomization, and the aerosol flows to the outside through the airway tube 2 and the gas outlet 11; and when the user smokes, the micro groove 41 and the micro hole 5 continuously absorb the aerosol substrate through the capillary principle, so as to ensure sufficient supply of the aerosol substrate.

[0034] The technical effects of the atomizer provided in the embodiments of the present application are as follows: (1) the flow guide channel 4 is formed in the atomizing core 3, and the micro hole 5 in communication with the airway tube 2 and the opening 12 is formed in the flow guide channel 4, the micro groove 41 and the micro hole 5 of the flow guide channel 4 absorb the aerosol substrate through the capillary principle, so that the present application can realize the absorption of the aerosol substrate without setting a cotton core or a ceramic core, avoiding the paste core caused by the direct action of the atomizing core 3 on the cotton core or the ceramic core during the atomization process, on the one hand, making the aerosol formed by the present application taste pure, and on the other hand, increasing the service life of the present application; (2) as the user smokes, the gas enters the atomizing core 3 from the micro hole 5, causing the aerosol substrate to be dispersed into fine particles, realizing primary atomization, the fine aerosol substrate particles come to the atomizing core 3 along with the airflow, the fine aerosol substrate particles are more easily atomized into aerosol by the atomizing core 3, realizing secondary atomization, and the two times of atomization are conducive to reducing the particle size of the aerosol, further increasing the taste of the aerosol and improving the experience of the user; and the structure of the present application for realizing the two times of atomization is simple, without setting two atomizing cores, and only the micro groove 41 and the micro hole 5 are formed to realize the two times of atomization, greatly reducing the production cost of the atomizer.

[0035] As Figure 5 shown, further, the flow guide channel 4 also includes a buffer area 42, the micro groove 41 communicates with the buffer area 42, the micro hole 5 is opened in the micro groove 41 and / or buffer area 42; the buffer area 42 can temporarily store the aerosol substrate introduced into the flow guide channel 4 by the micro groove 41, which is beneficial to the timely supply of the aerosol substrate when the user smokes.

[0036] In the embodiments of the present application, the micro hole 5 can be provided only in the micro groove 41, and the micro hole 5 can also be provided only in the buffer area 42; in a preferred embodiment, part of the micro hole 5 is provided in the micro groove 41, and the other part is provided in the buffer area 42.

[0037] Further, the width of the micro groove 41 is 100um-2.5mm; the distance between the two opposite points in the inner wall of the micro hole 5 is 10um-1mm, for example, 80um, 90um, etc.; of course, the width of the micro groove 41 and the distance between the two opposite points in the inner wall of the micro hole 5 are not limited to this, and can be adjusted according to actual needs, and when the micro hole 5 is arranged in the micro groove 41, the distance between the two opposite points in the inner wall of the micro hole 5 needs to be smaller than the width of the micro groove 41.

[0038] Further, the closer the micro hole 5 is to the center of the airway tube 2, the smaller the distance between the two opposite points in the inner wall of the micro hole 5; the gas flow rate at the center of the airway tube 2 is faster, and the smaller the distance between the two opposite points in the inner wall of the micro hole 5, that is, the smaller the diameter of the capillary, the greater the capillary force, which can adsorb the aerosol substrate faster, so in order to continuously and uninterruptedly supply the aerosol substrate, the present application sets the distance between the two opposite points in the inner wall of the micro hole 5 closer to the center of the airway tube 2 smaller.

[0039] Further, the closer the micro hole 5 is to the center of the airway tube 2, the smaller the gap between the micro holes 5; the gas flow rate at the center of the airway tube 2 is faster, and the more aerosol substrate is adsorbed in the denser area of the micro hole 5, so in order to continuously and uninterruptedly supply the aerosol substrate, the present application sets the distance between the two opposite points in the inner wall of the micro hole 5 closer to the center of the airway tube 2 smaller.

[0040] In a preferred embodiment, the closer the micro hole 5 is to the center of the airway tube 2, the smaller the distance between the two opposite points in the inner wall of the micro hole 5, and the closer the micro hole 5 is to the center of the airway tube 2, the smaller the gap between the micro holes 5; further guaranteeing the continuous and uninterrupted supply of the aerosol substrate.

[0041] In the embodiments of the present application, the micro-groove 41 can be located on the side of the atomizing core 3 facing the airway tube 2, or the micro-groove 41 can be located in the atomizing core 3; only the port of the micro-groove 41 needs to be in communication with the storage chamber 13, so that the effect of adsorbing the aerosol substrate can be achieved by the capillary principle.

[0042] Further, the micro-groove 41 is horizontally arranged on the side of the atomizing core 3 facing the airway tube 2; or the micro-groove 41 is arranged in the atomizing core 3 at an angle with the direction of the airflow, and the angle of the micro-groove 41 is less than 90°.

[0043] Further, the micro-hole 5 is vertically arranged and penetrates the atomizing core 3, and is in communication with the airway tube 2 and the opening 12; or the micro-hole 5 is arranged at an angle with the shell 1 and penetrates the atomizing core 3, and is in communication with the airway tube 2 and the opening 12, and the angle of the micro-hole is less than 90°.

[0044] In a preferred embodiment, the micro-groove 41 is horizontally arranged on the side of the atomizing core 3 facing the airway tube 2, and the micro-hole 5 is vertically arranged and penetrates the atomizing core 3, and is in communication with the airway tube 2 and the opening 12, so that the micro-hole 5 is vertically arranged with the micro-groove 41, the vertically arranged micro-hole 5 forms a gas passage with the air outlet 11 and the airway tube 2, which on the one hand facilitates the flow of gas from the micro-hole 5 to disperse the aerosol substrate when the user inhales, and on the other hand facilitates production.

[0045] Further, the airway tube 2 is threadedly connected or snap-connected with the air outlet 11, etc.

[0046] Preferably, the shell 1 and the airway tube 2 are integrally formed, the shell 1 is a hollow structure with one end being the opening 12, the end of the shell 1 away from the opening 12 is inwardly recessed to form the air outlet 11 and the airway tube 2, and the cavity in the shell 1 constitutes the storage chamber 13 arranged around the outer periphery of the airway tube 2, and the user injects the aerosol substrate into the storage chamber 13 through the opening 12.

[0047] As Figure 3 and Figure 4As shown, further, the atomization core 3 comprises an atomization tube 31, a sealing member 32 and an atomization member 33; the atomization tube 31 is connected with the air passage tube 2 and the sealing member 32 respectively, the sealing member 32 is arranged at the opening 12, and the outer wall of the sealing member 32 abuts against the inner wall of the shell 1, the atomization member 33 is connected with the sealing member 32 or the atomization tube 31 and located in the atomization tube 31; the flow guide passage 4 is arranged at the sealing member 32, the micro groove 41 is arranged on the side of the sealing member 32 facing the air passage tube 2 and the storage bin 13, and the micro hole 5 penetrates through both ends of the sealing member 32 and communicates with the atomization tube 31 and the opening 12. The sealing member 32 seals the opening 12 of the shell 1, which is used to prevent the aerosol substrate in the storage bin 13 from leaking out; the air outlet 11, the air passage tube 2, the atomization tube 31 and the micro hole 5 form a gas passage, when a user smokes, the gas enters the atomization tube 31 from the micro hole 5, the aerosol substrate is dispersed into fine particles to realize primary atomization, the fine aerosol substrate particle flow adheres to the atomization member 33 in the atomization tube 31, and the atomization member 33 atomizes the fine aerosol substrate particles into aerosol after being electrified to realize secondary atomization, and the aerosol flows to the outside through the air passage tube 2 and the air outlet 11.

[0048] In the embodiments of the present application, the atomization member 33 can be horizontally arranged, vertically arranged or obliquely arranged and connected with one end of the sealing member 32 facing the air passage tube 2, or the atomization member 33 can be horizontally arranged, vertically arranged or obliquely arranged and connected with the inner wall of the atomization tube 31.

[0049] In a preferred embodiment, the atomization member 33 is horizontally arranged and connected with one end of the sealing member 32 facing the air passage tube 2; when the fine aerosol substrate particle flow moves, the horizontally arranged atomization member 33 can adsorb more fine aerosol substrate particles, thereby increasing the atomization efficiency of the fine aerosol substrate particles; the connection between the atomization member 33 and the sealing member 32 can avoid the wall of the atomization tube 31 being too thick, the reduction of the wall thickness of the atomization tube 31 can increase the area of the storage bin 13, which is conducive to storing more aerosol substrate, and the increase of the inner wall diameter of the air passage tube 2 is conducive to the flow of gas.

[0050] More preferably, the outer wall of the atomization member 33 abuts against the inner wall of the atomization tube 31; when the fine aerosol substrate particle flow moves, the fine aerosol substrate particles cannot flow out from the gap between the atomization member 33 and the atomization tube 31, thereby further increasing the atomization efficiency of the fine aerosol substrate particles and the taste of the aerosol.

[0051] Of course, it can be understood that when the atomization member 33 is horizontally arranged and abuts against the inner wall of the atomization tube 31, the middle part of the atomization member 33 can also be provided with a through hole 332 for the flow of gas and aerosol as shown below.

[0052] As shown in Figure 5 Further, the plurality of micro-slots 41 are arranged on the side of the sealing member 32 facing the airway tube 2 and the storage bin 13, and are connected to or spaced from each other. The plurality of micro-slots 41 increase the adsorption efficiency of the atomization core 3.

[0053] Further, the plurality of micro-slots 41 are connected to the buffer area 42, which is beneficial to the timely supply of aerosol substrate when the user inhales.

[0054] Preferably, the plurality of micro-slots 41 are arranged at equal intervals along the midpoint of the side of the sealing member 32 facing the airway tube 2. When the user inhales, the gas enters the atomization tube 31 from the micro-holes 5, and the aerosol substrate is uniformly dispersed into fine particles, which is beneficial to the atomization of the fine aerosol substrate particles into aerosol by the atomization member 33, and increases the atomization efficiency of the fine aerosol substrate particles.

[0055] In a preferred embodiment, the buffer area 42 is arranged at the midpoint of the side of the sealing member 32 facing the airway tube 2, and the plurality of micro-slots 41 are arranged at equal intervals along the buffer area 42. This not only ensures the timely supply of aerosol substrate, but also uniformly disperses the aerosol substrate into fine particles, further improving the user experience.

[0056] Further, the sealing member 32 comprises a first sealing part 321 and a second sealing part 322. The first sealing part 321 is arranged at the opening 12, and the outer wall of the first sealing part 321 abuts against the inner wall of the shell 1. The second sealing part 322 is arranged on the side of the first sealing part 321 facing the airway tube 2, and the outer wall of the second sealing part 322 abuts against the inner wall of the atomization tube 31. The atomization member 33 is arranged at one end of the second sealing part 322 facing the airway tube 2. The flow guide channel 4 is arranged at the first sealing part 321 and the second sealing part 322. The micro-slots 41 are arranged on the side of the first sealing part 321 and the second sealing part 322 facing the atomization tube 31. The micro-holes 5 penetrate the first sealing part 321 and the second sealing part 322 to communicate with the atomization tube 31 and the opening 12. The first sealing part 321 seals the opening 12 of the shell 1, and the second sealing part 322 seals the atomization tube 31, preventing the aerosol substrate in the storage bin 13 from leaking out of the opening 12 or directly entering the atomization tube 31, and increasing the sealing performance of the present application.

[0057] Further, the outer wall of the first sealing part 321 is provided with an abutting part 323, which tightly abuts against the inner wall of the shell 1, thereby ensuring the sealing performance of the opening 12 of the shell 1.

[0058] Furthermore, there are multiple abutment portions 323, which are spaced apart to further ensure the sealing of the opening 12 of the housing 1.

[0059] Furthermore, the second sealing part 322 is a hollow ring. The atomizing element 33 is located at one end of the second sealing part 322 facing the airway tube 2. The flow guiding channel 4 is located at the first sealing part 321. The microgroove 41 is located on the side of the first sealing part 321 facing the atomizing tube 31. The micropore 5 penetrates the first sealing part 321 and communicates with the hollow part of the second sealing part 322. The hollow structure of the second sealing part 322 allows the atomizing element 33 to adsorb more fine aerosol matrix particles, increasing the atomization efficiency of fine aerosol matrix particles. By spacing the atomizing element 33 from the first sealing part 321 through the second sealing part 322, direct contact between the atomizing element 33 and the aerosol matrix in the microgroove 41 and micropore 5 of the first sealing part 321 is prevented. The atomizing element 33 can more easily atomize the dispersed fine aerosol matrix particles, which helps to reduce the particle size of the aerosol, further improving the aerosol taste and enhancing the user experience.

[0060] Furthermore, the second sealing part 322 has an installation groove 324 at one end facing the airway tube 2, and the atomizing element 33 is disposed in the installation groove 324. The atomizing element 33 is disposed in the installation groove 324 of the second sealing part 322, and then the second sealing part 322 is inserted into the atomizing tube 31 to prevent the outer wall of the atomizing element 33 from directly abutting against the inner wall of the atomizing tube 31, thereby avoiding damage to the atomizing tube 31 when the atomizing element 33 atomizes. Under the action of the second sealing part 322, the fine aerosol matrix particles cannot flow out from the gap between the atomizing element 33 and the atomizing tube 31, which can ensure the atomization efficiency of the fine aerosol matrix particles and the aerosol taste.

[0061] Furthermore, the second sealing part 322 is divided into multiple equal parts along the microgroove 41; if the second sealing part 322 is a complete ring, it cannot be integrated with the first sealing part 321 for integrated production, thus facilitating the integrated molding of the first sealing part 321 and the second sealing part 322.

[0062] Furthermore, the sealing element 32 is a silicone element. Silicone has the characteristics of temperature resistance, weather resistance, electrical insulation and physiological inertness, which makes the sealing element 32 have a long service life and prevents the atomizing element 33 from directly acting on the aerosol matrix in the micropores 5 and microgrooves 41, thus ensuring the technical effect of secondary atomization in this application.

[0063] like Figure 6As shown, the atomizing core 3 further includes a conductive element 34, the atomizing element 33 is connected to the conductive element 34, the conductive element 34 passes through the sealing element 32 and is electrically connected to the outside, and the atomizing element 33 atomizes the fine aerosol matrix particles into aerosol after being energized through the conductive element 34.

[0064] like Figure 5 As shown, the first sealing part 321 is further provided with a mounting hole 325 through which the conductive element 34 passes, and the mounting hole 325 is spaced apart from the micropore 5.

[0065] Furthermore, the atomizing component 33 is a heating component, which includes a heating element 331. The heating element 331 is disposed at one end of the sealing component 32 facing the airway tube 2, and the heating element 331 is connected to the conductive component 34. The heating element 331 heats up after being energized through the conductive component 34, and heats and atomizes the fine aerosol matrix particles into aerosol.

[0066] In one embodiment, when the heating component is horizontally arranged, the heating element 331 has multiple through holes 332 for airflow and aerosol circulation, so that the air outlet 11, air passage 2, atomizing tube 31, through holes 332 and micropores 5 form an air passage.

[0067] In a preferred embodiment, the heating element 331 is a metal felt; the metal felt has a three-dimensional mesh porous structure. If the metal felt is used as the heating element 331, there is no need to open additional through holes on the heating element 331.

[0068] More preferably, the heating element 331 is disposed in the mounting groove 324; to prevent the outer wall of the heating element 331 from directly abutting against the inner wall of the atomizing tube 31, and to avoid damage to the atomizing tube 31 when the atomizing element 33 performs atomization.

[0069] Furthermore, the atomizing element 33 is an ultrasonic component (not shown), which includes an oscillating plate.
