The specific structure and function of the atomizer 1 can be referred to as the specific structure and function of the atomizer 1 according to the following embodiments, and the same or similar technical effects can be achieved, which are not described herein.

The host machine 2 is used for supplying power to the atomizer 1 and controlling the atomizer 1 to atomize. Specifically, the main unit 2 includes a battery and a control element that is electrically connected to the battery and controls the supply of power to the atomizer 1.

Referring to fig. 2 to 6, fig. 2 is a schematic perspective view of an atomizer according to an embodiment of the present application, fig. 3 is a schematic cross-sectional view of the atomizer shown in fig. 2 along A-A direction, fig. 4 is an enlarged schematic perspective view of a region a shown in fig. 3, fig. 5 is an exploded schematic view of the structure shown in fig. 4, and fig. 6 is a schematic airflow direction and a liquid direction of the atomizer shown in fig. 3.

The atomizer 1 comprises a housing 11, a bracket 12, a base 13, a support seat 14 and two heating components 15. The bracket 12, the base 13 and the supporting seat 14 are arranged in the shell 11; both heating elements 15 are provided on the support 12.

The end of the bracket 12 is detachably connected with the end of the base 13; illustratively, a hook is disposed on one of the support 12 and the base 13, and a slot is disposed on the other of the support 12 and the base 13, and the slot is matched with the hook to realize the snap connection between the support 12 and the base 13. The support seat 14 is arranged between the bracket 12 and the base 13, the support seat 14 is detachably connected with the bracket 12, and the support seat 14 is detachably connected with the base 13; illustratively, one end of the supporting seat 14 abuts against the bracket 12, and the other end of the supporting seat 14 abuts against the base 13. In other embodiments, the base 13 and the support base 14 are integrally formed, and the base 13 and the support base 14 are detachably connected (e.g., snap-fit connection) to the stand 12 as a unitary structure.

The interior of the housing 11 forms a reservoir 10 for containing a liquid matrix. In particular, the inner surface of the housing 11 and the end of the support 12 remote from the base 13 define a reservoir 10, the reservoir 10 being for storing an aerosol-generating substrate, for example a liquid substrate. The base 13 covers the open end of the housing 11. Two heating elements 15 are in fluid communication with the reservoir 10, respectively, to atomize the aerosol-generating substrate stored within the reservoir 10. By providing two heating elements 15, the atomization efficiency can be improved; the atomization efficiency can be improved by 2 times compared with a single heating component under the condition of the air inflow with the same volume. In addition, when one of the heating components 15 is damaged, the atomizer 1 can be normally used, and the service life of the atomizer 1 is prolonged.

The bracket 12 defines a mounting slot 121, an air outlet 122, and a lower liquid orifice 1211 for directing the flow of the liquid matrix. The lower liquid hole 1211 communicates between the liquid storage chamber 10 and the mounting groove 121 to provide a liquid matrix flow path therebetween, i.e., the liquid matrix in the liquid storage chamber 10 flows through the lower liquid hole 1211 to the mounting groove 121. Alternatively, the lower liquid hole 1211 is formed in the bottom wall of the mounting groove 121. The two heating components 15 are all arranged in the mounting groove 121 and are respectively positioned at two opposite sides of the air outlet hole 122. The axis of the lower liquid hole 1211 is substantially parallel to the axis of the air outlet hole 122. Wherein, the substantially parallel means that the included angle formed by the axis of the lower liquid hole 1211 and the axis of the air outlet hole 122 is 0 ° or more than 0 ° and less than or equal to 15 °, and the axis of the upper liquid hole 1211 is parallel to the axis of the air outlet hole 122; it should be noted that, in the following description, the substantial parallelism is similar to that described above, and visual parallelism is only required. The two heat generating components 15 are respectively provided with a liquid outlet 1211, and the two heat generating components 15 are respectively communicated with the liquid storage cavity 10 through the corresponding liquid outlet 1211, i.e. the heat generating components 15 receive the liquid matrix through the liquid outlet 1211. The aerosol-generating substrate in the reservoir 10 flows along the axial direction of the lower liquid orifice 1211 towards the heat-generating component 15 in the mounting cup 121. Since the lower liquid hole 1211 is positioned below the liquid storage chamber 10 when the atomizer 1 is vertically placed with the base 13 facing downward, by arranging the axis of the lower liquid hole 1211 to be parallel to the axis of the air outlet hole 122, it is possible to facilitate smooth guiding of the aerosol-generating substrate in the liquid storage chamber 10 into the mounting groove 121 and complete utilization of the aerosol-generating substrate in the liquid storage chamber 10.

The support 12 is further formed with two lower liquid channels 123, the two lower liquid channels 123 are located at two opposite sides of the air outlet 122, and the two lower liquid channels 123 are arranged in one-to-one correspondence with the two heating components 15. The axis of the lower liquid passage 123 is substantially parallel to the axis of the air outlet hole 122. The lower liquid hole 1211 communicates with the liquid storage chamber 10 through the lower liquid passage 123, i.e., the aerosol-generating substrate within the liquid storage chamber 10 flows into the lower liquid hole 1211, and thus into the heat generating component 15, through the lower liquid passage 123.

The two heat generating components 15 are in fluid communication with the air outlet holes 122, respectively. The housing 11 is formed with a mist outlet passage 111, the air outlet hole 122 communicates with the mist outlet passage 111, and the axis of the air outlet hole 122 coincides with the axis of the mist outlet passage 111. The aerosol-generating substrate is atomized by the heat generating components 15 positioned in the mounting groove 121 to generate aerosol, both heat generating components 15 are in fluid communication with the air outlet holes 122, the aerosol generated by the atomization of the two heat generating components 15 flows out of the air outlet holes 122 to the mist outlet channel 111, and a user sucks the aerosol through the port of the mist outlet channel 111. It will be appreciated that the present embodiment provides an atomizer 1 in which the direction of the liquid discharge (parallel to the axial direction of the air outlet 122) coincides with the direction of the air flow (along the axial direction of the air outlet 122).

The heating assembly 15 includes an atomizing face 15a, the atomizing face 15a being in fluid communication with the air outlet aperture 122, the atomizing face 15a forming a first included angle with the axis of the air outlet aperture 122, the first included angle being an acute angle. Alternatively, the first included angle is 5 ° -85 °, such that the heat generating component 15 is disposed obliquely. In suitable examples, the first included angle is 25 ° -75 °, for example, the first included angle is 75 ° or 60 ° or 45 ° or 30 ° or 25 °.

The axis of the liquid outlet 1211 forms a third angle with the atomizing surface 15a, and the third angle is an acute angle. Optionally, the third included angle is the same as the first included angle.

The supporting seat 14 is formed with two mutually independent atomizing channels 141, and two atomizing channels 141 and two heating components 15 one-to-one set up for the air current of every heating component 15 is more even, and the gas flow is more smooth and easy, does benefit to promoting atomization efficiency, makes atomizer 1 produce better taste simultaneously. The atomizing passage 141 includes an inlet section 1411, an atomizing section 1412, and an outlet section 1413, which are sequentially communicated, the inlet section 1411 being in gaseous communication with the outside, the atomizing section 1412 being in fluid communication with the atomizing face 15a, and the outlet section 1413 being in communication with the outlet aperture 122. The axis of the inlet section 1411 is substantially parallel to the axis of the outlet aperture 122. The axis of the gas outlet segment 1413 forms a second angle with the axis of the gas outlet aperture 122, the second angle being greater than 0 °. The air inlet section 1411 and the air outlet section 1413 are arranged in such a way that the atomizing passage 141 forms a corner, and the atomizing section 1412 is at the corner; in other words, the atomizing passage 141 resembling an "r" is formed after the air flow passes the heat generating component 15 before the air flow passes the heat generating component 15, and passes the heat generating component 15.

Through the inclined arrangement of the heating component 15 and the design of the atomizing channel 141, after the airflow impacts the heating component 15, atomized aerosol at the corner of the atomizing channel 141 is taken away, and the mouthfeel is better. Compared with the situation that the atomizing surface of the heating component is parallel to the axis of the air outlet hole in the prior art, the atomizer 1 provided by the embodiment of the application obviously improves the taste.

In the present embodiment, the intake section 1411 includes a first sub-intake section 1411a and a second sub-intake section 1411b that communicate with each other. The second sub-inlet section 1411b is located on a side of the first sub-inlet section 1411a remote from the atomizing section 1412. Along the axial direction of the second sub-intake section 1411b, the sectional area and the sectional shape of the second sub-intake section 1411b are uniform. Along the axis of the first sub-intake section 1411a and in a direction toward the atomizing section 1412, the cross-sectional shape of the first sub-intake section 1411a is uniform, and the cross-sectional area of the first sub-intake section 1411a gradually increases. The cross-sectional area and the cross-sectional shape of the gas outlet section 1413 are uniform along the axial direction of the gas outlet section 1413. The structures of the air inlet section 1411 and the air outlet section 1413 are not limited to the above-mentioned designs, and the design is specifically performed according to the need, so that the entire atomizing channel 141 can be formed with a corner, and the air flow can impact the heating element 15 and then take away the aerosol at the corner.

The support base 14 is also formed with a communication groove 142. The communication groove 142 communicates with the air outlet hole 122. The depth direction of the communication groove 142 coincides with the axial direction of the air outlet hole 122. The two atomizing passages 141 are located on opposite sides of the communication groove 142, respectively. The gas outlet section 1413 communicates with the gas outlet hole 122 through the communication groove 142.

Two first liquid collecting tanks 131 are formed on the base 13. The two first liquid collecting tanks 131 are arranged in one-to-one correspondence with the two air inlet sections 1411; in other words, the two first liquid collecting tanks 131 are disposed in one-to-one correspondence with the two atomizing channels 141, and the first liquid collecting tanks 131 communicate with the atomizing channels 141 and extend away from the heat generating component 15. Specifically, the first liquid collection tank 131 communicates with the intake section 1411, and the axis of the first liquid collection tank 131 coincides with the axis of the intake section 1411. Since the upper portion of the air intake section 1411 is aligned with the atomizing section 1412, the atomizing section 1412 is in fluid communication with the heat generating component 15, leakage (leakage of aerosol-generating substrate) from the lower liquid orifice 1211 during atomization, and condensate on the wall surface of the atomizing section 1412 flows into the first liquid collecting tank 131, so that leakage to the outside of the atomizer 1 can be prevented.

The base 13 is further formed with a second liquid collecting tank 132, and the second liquid collecting tank 132 is located between the two first liquid collecting tanks 131. The second sump 132 is in communication with the air outlet aperture 122, and the second sump 132 extends away from the air outlet aperture 122. Specifically, the axis of the second liquid collection tank 132 coincides with the axis of the air outlet hole 122. Wherein, a through hole 1421 is provided on the bottom wall of the communication slot 142, and the second liquid collecting slot 132 is communicated with the air outlet hole 122 through the through hole 1421 and the communication slot 142. The second liquid collecting groove 132 may be used to collect condensate formed on the wall surfaces of the air outlet hole 122 and the mist outlet channel 111, so as to avoid liquid leakage to the outside of the atomizer 1. Because the second sump 132 is independent of the first sump 131, a user may be prevented from sucking in aerosol-generating substrate collected by the first sump 131.

With continued reference to fig. 4 and 5, the support base 14 and the base 13 cooperate to form two mutually independent ventilation channels 130, the two ventilation channels 130 are disposed in one-to-one correspondence with two air intake sections 1411, and the air intake sections 1411 are in communication with the outside air through the ventilation channels 130. The two ventilation channels 130 are located between the two first liquid collection tanks 131 and on opposite sides of the second liquid collection tank 132. The ventilation channel 130 is independent of the first and second liquid collecting tanks 131 and 132, and can prevent liquid collected in the first and second liquid collecting tanks 131 and 132 from being sucked. The axis of the vent channel 130 is substantially parallel to the axis of the intake section 1411. The first liquid collecting tank 131 is provided with an opening 1311, and the air inlet section 1411 communicates with the ventilation channel 130 through the opening 1311. In one embodiment, the opening 1311 is a notch at the open end of the first sump 131, such that the first sump 131 is filled with liquid and leaks from the vent channel 130 to the outside of the atomizer 1.

Specifically, the support base 14 is formed with two ventilation grooves 143. Two vent holes 133 are formed in the base 13, the two vent holes 133 are respectively located at two opposite sides of the second liquid collecting tank 132, and the vent holes 133 are communicated with external air. The two ventilation grooves 143 are arranged in one-to-one correspondence with the two ventilation holes 133; the vent slot 143 and vent hole 133 cooperate to form the vent channel 130. The vent slot 143 is provided with an opening (not shown), and ambient air flows into the intake section 1411 through the vent hole 133, the vent slot 143, the opening in the vent slot 143, and the opening 1311 in the first liquid collection tank 131.

Referring to fig. 7 and 8, fig. 7 is a schematic structural view of a bracket of the atomizer shown in fig. 3, and fig. 8 is a schematic structural view of a heat generating component shown in fig. 3.

The bottom wall of the mounting groove 121 is provided with a positioning column 1212. The heating element 15 is provided with a positioning opening 150. The positioning opening 150 is matched with the positioning column 1212 to position the heating element 15 in the width direction of the atomizer 1. Optionally, the positioning posts 1212 are attached to the side walls of the mounting groove 121, and the positioning openings 150 are notches formed at the edges of the heat generating component 15, so as to avoid affecting atomization of the heat generating component 15.

The heat generating component 15 includes a liquid guide 151 and a heat generating element 152. The liquid guide 151 is provided with the positioning port 150. The liquid guide 151 includes an atomization surface 15a and a liquid suction surface 15b opposite to the atomization surface 15a, the liquid suction surface 15b is adhered to the bottom wall of the mounting groove 121, and the heating element 152 is disposed on the atomization surface 15a of the liquid guide 151; that is, the surface of the liquid guide 151 facing away from the bottom wall of the mounting groove 121 is the atomizing face 15a. The heat generating element 152 comprises a heat generating part 1521 for atomizing an aerosol generating substrate to generate an aerosol, and an electrode 1522 for electrically connecting the heat generating part 1521 with the host 2. In one embodiment, the two heating elements 152 are independent of each other; the two liquid guide members 151 of the two heating components 15 are connected to ensure sufficient liquid supply. In some embodiments, the liquid guide 151 uses a capillary core material having a capillary effect, such as cotton fiber or polymer fiber material, and the liquid guide 151 may also use a porous material having a plurality of micropores therein, such as porous ceramic, porous glass, or porous metal. The heating element 152 is a heating sheet or a heating wire with a specific shape, and the heating element 152 can be attached to the surface of the liquid guide 151 in an assembling manner; in some examples, the heat-generating element 152 includes heat-generating circuitry that is bonded to the surface of the liquid guide 151 (e.g., porous ceramic) by printing, deposition, or etching.

As a suitable example, the liquid guide 151 includes a fiber cotton sheet having a shape matching the shape of the mounting groove 121, the fiber cotton sheet being received inside the mounting groove 121 and blocking the liquid discharge hole 1211, and the heating element 152 is a metal sheet having a specific shape formed by etching, the metal sheet being adhered to a surface of the fiber cotton sheet by a peripheral structure for heating the liquid matrix held in the fiber cotton sheet when energized. The fiber cotton sheet may comprise a plurality of stacked fiber layers, the fiber orientations of the different fiber layers being non-uniform or staggered, which is advantageous for retaining the liquid matrix locked inside the liquid guide 151 to prevent excessive liquid leakage from the liquid guide 151.

With continued reference to fig. 4, the end of the supporting seat 14 abuts against a portion of the heating element 152, so that the heating element 152 is attached to the surface of the liquid guiding member 151, so that the heating element 152 is tightly combined with the liquid guiding member 151, and the heating element 152 is prevented from being dry-burned due to separation of the heating element 152 and the liquid guiding member 151; meanwhile, the liquid guide 151 can be tightly attached to the liquid outlet 1211, and liquid leakage caused by a gap between the liquid guide 151 and the liquid outlet 1211 can be prevented.

The atomizer 1 further comprises two conducting posts 16. The conductive post 16 is fixed to the base 13. After the support 12 is detachably connected with the base 13, the conducting post 16 is pressed on the electrode 1522 of the heating element 152 to form a conducting circuit, so that welding-free is realized.

In one embodiment, the electrodes 1522 of the two heat generating components 15 are connected in parallel between the two conductive posts 16. Since the two heat generating components 15 are both disposed obliquely, two inclined surfaces 161 are formed on the end surfaces of the via post 16 (i.e., the end of the via post 16 has the inclined surface 161 contacting the electrode 1522), the inclined surfaces 161 of the via post 16 are disposed in cooperation with the inclination angle of the heat generating components 15, and one inclined surface is bonded to the electrode 1522 of one heat generating component 15.

With continued reference to fig. 3, in one embodiment, the inner surface of the housing 11 and the end of the bracket 12 remote from the base 13 define a reservoir 10, with both heating elements 15 communicating with the reservoir 10; compared with a single-shot heating assembly, the two heating assemblies 15 atomize aerosol generating matrixes in the same liquid storage cavity 10 at the same time under the condition of the air inflow of the same volume, the atomization efficiency is improved by 2 times, and the taste of explosive force is enhanced.

In one embodiment, the inner surface of the housing 11 and the end of the bracket 12 define two separate fluid reservoirs 10, the two fluid reservoirs 10 being in one-to-one fluid communication with two heat generating components 15. Optionally, the aerosol-generating substrates stored in the two liquid storage chambers 10 have different tastes, the atomizing channels 141 corresponding to the two heating components 15 are mutually independent, so that the aerosol-generating substrates with different tastes are independently atomized, and then are mixed at the air outlet 122, thereby bringing novel feeling and experience to the user.

In one embodiment, the atomizer 1 assumes a flat appearance having a width dimension perpendicular to its length and a thickness dimension, wherein the thickness dimension is less than the width dimension. The two heating elements 15 are located at opposite sides of the air outlet 122 along the width direction of the atomizer 1, and such an arrangement is advantageous for providing a sufficient installation space for the two heating elements 15 and adjusting the inclination angle of the heating elements 15 during the design stage; meanwhile, the two corresponding liquid discharging channels 123 are also arranged along the width direction of the atomizer 1, so that the sectional area of the liquid discharging channels 123 can be increased, the efficiency of liquid transmission is improved, and bubbles formed by air from the atomization cavity entering the liquid discharging channels 123 are prevented from accumulating in the liquid discharging channels, so that the liquid transmission is prevented; wherein the width direction of the atomizer 1 coincides with the direction of the line A-A shown in fig. 2.

The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
