The present application relates to an atomizer and an electronic atomization device. The atomizer comprises an atomization core assembly, the atomization core assembly comprising a plurality of atomization cores arranged side by side, each atomization core having a longitudinal direction and a width direction intersecting with the longitudinal direction, and the plurality of atomization cores being arranged in the width direction; a gas flow channel communicated with the atomization cores is formed in the atomizer, the gas flow channel at least partially surrounding two opposite sides of the atomization core assembly in the width direction.

Background Art

Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, electronic atomization devices that can heat liquid or solid aerosol-generating substrates to generate aerosols are used in different fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

Referring to FIGS. 1 to 5 , in one embodiment of the present application, an atomizer 100 is provided, including an atomizer core assembly 10. The atomizer core assembly 10 includes a plurality of atomizer cores 12 arranged side by side. Each atomizer core 12 has a longitudinal direction A and a width direction B intersecting the longitudinal direction A. The plurality of atomizer cores 12 are arranged along the width direction B, which is equivalent to one side of a certain atomizer core 12 along its own width direction B being another atomizer core 12. In this way, the plurality of atomizer cores 12 are arranged side by side in the width direction B to increase the atomization amount.

It can be understood that after the atomizer core 12 absorbs the aerosol generating substrate, it heats and atomizes the aerosol generating substrate absorbed by itself, so as to atomize the aerosol generating substrate into an aerosol. In addition, the length in the longitudinal direction A is greater than the length in the width direction B, and the atomizer core 12 is in the shape of a long strip, so that the atomizer core 12 has a rectangular liquid inlet surface, and the area of the liquid inlet surface is large, which can better absorb the aerosol generating substrate.

The atomizer 100 has an airflow channel 30 formed inside thereof, which is connected to the atomizer core 12. After entering the atomizer 100, the external airflow flows through the atomizer core 12, carries the atomized aerosol to the airflow channel 30, and finally flows out for the user to inhale. In addition, the airflow channel 30 is at least partially arranged around the atomizer core assembly 10 on two opposite sides in the width direction B. The external airflow enters the atomizer core 12 and flows through the atomizer core 12. After the atomizer 100, the airflow flows along the opposite sides of the width direction B of the atomizer core assembly 10 through the airflow channel 30. Compared with the airflow flowing around the opposite sides of the length direction of the atomizer core assembly 10, the flow path of the airflow is shorter, and the atomized aerosol can be carried out by the airflow faster, thereby improving the atomization efficiency.

According to some embodiments of the present application, the atomizer 100 has a first direction C, a second direction D and a third direction E. The atomizer 100 extends along the first direction C and has a central axis along the first direction C. The second direction D and the third direction E intersect with each other and intersect with the first direction C. In this embodiment, the second direction D and the third direction E are both perpendicular to the first direction C. The width of the atomizer 100 in the second direction D is greater than the width of the atomizer 100 in the third direction E, that is, the atomizer 100 is configured as a rod extending longitudinally along the first direction C, and the cross-sectional shape of the atomizer 100 along the perpendicular first direction C is a rectangular or elliptical or polygonal shape. The width of the atomizer 100 along the second direction D or the third direction E can be understood as the maximum width in the corresponding direction. In a specific embodiment, the atomizer 100 is configured as a flat rod as a whole, and further, the cross-sectional shape of the atomizer 100 along the perpendicular first direction C is a rectangle.

In a specific embodiment, the width direction B of the atomizer core 12 is consistent with the second direction D of the atomizer 100, that is, the plurality of atomizer cores 12 are arranged at intervals along the second direction D of the atomizer 100; or the width direction B of the atomizer core 12 is consistent with the third direction E of the atomizer 100, that is, the plurality of atomizer cores 12 are arranged at intervals along the third direction E of the atomizer 100. In a specific embodiment, the number of atomizer cores 12 is two, and the two atomizer cores 12 are arranged at intervals along the second direction D or the third direction E of the atomizer 100. In other embodiments, the number of atomizer cores may be 3, 4, etc., without limitation.

In some embodiments, when the atomizer core assembly 10 is installed inside the atomizer 100, the width direction B of the atomizer core 12 is consistent with the second direction D of the atomizer 100, that is, the plurality of atomizer cores 12 are arranged at intervals in the second direction D of the atomizer 100, so that the plurality of atomizer cores 12 are arranged in the second direction D of the atomizer 100 where the width is larger, and the airflow flows out from the atomizer core assembly 10 on opposite sides in the second direction D, and the aerosol generating matrix flows to the atomizer core 12 from opposite sides in the third direction E of the atomizer 100, and the liquid supply path and the airflow path are staggered to prevent interference.

6-8 , in some other embodiments, when the atomizer core assembly 10 is installed inside the atomizer 100, the width direction B of the atomizer core 12 is consistent with the third direction E of the atomizer 100, that is, the plurality of atomizer cores 12 are arranged at intervals in the third direction E of the atomizer 100. In this way, the plurality of atomizer cores 12 are arranged in the third direction E of the atomizer 100 where the width is smaller, and the airflow flows out from the atomizer core assembly 10 on two opposite sides in the third direction E, and the aerosol generating matrix flows from the atomizer 100 on two opposite sides in the second direction D to the edgeless core, and the liquid supply path and the airflow path are staggered to prevent interference.

Specifically in one embodiment, each atomizing core 12 has an atomizing surface 121, and the atomizing surfaces 121 of the multiple atomizing cores 12 face the same side of the first direction C, and are all connected to the airflow channel 30. In this way, the atomizing surfaces 121 of the multiple atomizing cores 12 are all located on the same side of the first direction C, and after the external airflow flows toward the inside of the atomizer 100 along the first direction C extending from the atomizer 100, it contacts the atomizing surfaces 121 of the multiple atomizing cores 12, and then carries the aerosol generated by atomization to flow toward the airflow channel 30 to be supplied to the user for inhalation and consumption.

Further, the atomizer 100 includes a base 50 and a bracket 70 assembled with the base 50, an atomizing chamber 60 connected with the airflow channel 30 is defined between the bracket 70 and the base 50, and the atomizing core assembly 10 is arranged in the atomizing chamber 60, that is, between the bracket 70 and the base 50, and the atomizing surface 121 of the atomizing core 12 is all facing the base 50 and is in fluid communication with the atomizing chamber 60. In this way, the bracket 70 is assembled and supported by the base 50, and the atomizing core assembly 10 is installed by the bracket 70, and the external airflow can flow to the atomizing chamber 60 and contact all the atomizing surfaces 121 to carry the atomized aerosol.

According to some embodiments of the present application, the airflow channel 30 includes a first airflow channel 32 and a second airflow channel 34 both of which are connected to the atomizing chamber 60, and the first airflow channel 32 and the second airflow channel 34 are respectively located on opposite sides of the width direction B of the atomizing core assembly 10. In this way, after the external airflow flows into the atomizing chamber 60, a part of the airflow flows into the first airflow channel 32, and the other part of the airflow flows into the second airflow channel 34, that is, it flows around the atomizing core assembly 10 on opposite sides in the width direction B, the flow path is short, and the atomization efficiency is high.

Optionally, the airflow channel also includes a third airflow channel 36 opposite to the atomizing chamber 60. On one side of the width direction B of the atomizing core 12, the first airflow channel 32 connects one side of the atomizing chamber 60 with the third airflow channel 36; on the other side of the width direction B of the atomizing core 12, the second airflow channel 34 connects the other side of the atomizing chamber 60 with the third airflow channel 36. In this way, the atomizing chamber 60, the first airflow channel 32, the second airflow channel 34 and the third airflow channel 36 are interconnected to form a square flow path. After the external airflow flows to the atomizing chamber 60, it flows around the opposite sides of the atomizing core assembly 10 in the width direction B, and finally flows out after merging in the third airflow channel 36.

Further, the bracket 70 includes a body 72 and a mounting portion 74 disposed in the body 72, and the atomizer core assembly 10 is mounted inside the mounting portion 74; along the width direction B of the atomizer core 12, the mounting portion 74 is spaced apart from the body 72 on opposite sides to form a first airflow channel 32 and a second airflow channel 34. In this way, the atomizer core assembly 10 is accommodated and assembled through the mounting portion 74, and the first airflow channel 32 and the second airflow channel 34 are formed outside the mounting portion 74, so that the airflow flows around the atomizer core assembly 10 on both sides of the mounting portion 74 in the width direction B, and the flow path is short.

Referring to FIGS. 2 to 5 , according to some embodiments of the present application, the atomizer 100 further includes a baffle 80, which is disposed on the base 50 and between the base 50 and the atomizing surface 121. The baffle 80 is provided with an air hole 81 connecting the atomizing surface 121 with the outside world. In this way, the outside airflow first flows between the baffle 80 and the atomizing surface 121 through the air hole 81 on the baffle 80 to carry the aerosol formed by atomization from the atomizing surface 121. In addition, the baffle 80 blocks the side of the atomizing surface 121 facing the base 50, and the baffle 80 can be used to prevent the aerosol generated by atomization from diffusing into the base 50, so that the aerosol after atomization is more concentrated upward, thereby reducing the loss of aerosol inside the atomizer 100.

Furthermore, the baffle 80 is projected toward the atomizer core assembly 10, exceeds the atomizer core assembly 10 and extends to the airflow channel 30. In this way, the baffle 80 blocks the aerosol generated by atomization from flowing toward the base 50, and guides the aerosol to flow into the airflow channel 30.

Specifically, the baffle 80 has a converging portion 82, a first diverting portion 84, and a second diverting portion 86. The second flow dividers 86 are respectively arranged on opposite sides of the confluence portion 82 along the width direction B of the atomizer core 12, and are respectively opposite to different atomization surfaces 121. The confluence portion 82 has an air inlet groove 821 connected to the outside, and the first flow divider 84 and the second flow divider 86 are both connected to the air inlet groove 821 toward the side of the atomizer core 12 facing each other.

In this way, when the user uses the atomizer 100 for inhalation, the external airflow first flows to the air inlet groove 821 of the converging portion 82, and then part of the airflow flows to between the first diverter portion 84 and the atomizing surfaces 121 of a plurality of atomizing cores 12, while another part of the airflow flows to between the second diverter portion 86 and the atomizing surfaces 121 of the remaining atomizing cores 12. In this way, through the cooperation of the converging portion 82, the first diverter portion 84 and the second diverter portion 86 on the baffle 80, the external airflow enters between the baffle 80 and the atomizing surface 121, and then flows to the opposite sides of the width direction B of the atomizing core 12, so as to smoothly flow from the atomizing chamber 60 to the airflow channel 30.

Furthermore, the air holes 81 include a first air hole 812 and a second air hole 814. The confluence portion 82 protrudes toward the direction close to the atomizer core assembly 10 and forms an air inlet groove 821 therein. The confluence portion 82 is provided with a first air inlet hole and a second air inlet hole connected to the air inlet groove 821 on opposite sides along the width direction B of the atomizer core 12, respectively.

When the user uses the atomizer 100 for inhalation, the external airflow first flows to the air inlet groove 821 of the converging portion 82, and then part of the airflow flows through the first air inlet hole to between the first diverter portion 84 and the atomizing surfaces 121 of a plurality of atomizing cores 12, while another part of the airflow flows through the second air inlet hole to between the second diverter portion 86 and the atomizing surfaces 121 of the remaining atomizing cores 12. In this way, through the cooperation of the converging portion 82, the first diverter portion 84 and the second diverter portion 86 on the baffle 80, the external airflow enters between the baffle 80 and the atomizing surface 121, and then flows to the opposite sides of the width direction B of the atomizing core 12, so as to smoothly flow from the atomizing chamber 60 to the airflow channel 30.

Optionally, the axial direction of the first air hole 812 and the axial direction of the second air hole 814 are both parallel to the atomizing surface 121, so that the air flow is guided by the first air hole 812 and the second air hole 814 to flow in the atomizing chamber 60 along a direction parallel to the atomizing surface 121, flows smoothly in the atomizing chamber 60 and effectively carries the aerosol generated by atomization.

According to some embodiments of the present application, the present application also provides an electronic atomization device, including a power supply assembly and the atomizer 100 described in any of the above embodiments, the power supply assembly is used to supply power to the atomizer 100, and the atomizer 100 can heat the atomized aerosol to generate a matrix after being powered on.

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
