[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features.

[0049] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] See also Figure 1 to Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of an electronic atomization device provided by the present application, Figure 2 yes Figure 1 A schematic cross-sectional view of an electronic atomization device is provided.

[0051] See also Figure 1 and Figure 2 The present application provides an electronic atomization device 300, which can be used for atomization of an aerosol-generating substrate. The electronic atomization device 300 includes an atomizer 100 and a power supply assembly 200 electrically connected to each other.

[0052] The atomizer 100 is used to store an aerosol-generating matrix and atomize the aerosol-generating matrix to form an aerosol that can be inhaled by the user. The aerosol-generating matrix can be a liquid matrix such as a liquid medicine, a plant leaf liquid, etc. The atomizer 100 can be used in different fields, such as medical treatment, beauty, electronic aerosolization, etc. The power supply assembly 200 includes a battery 201, an airflow sensor (not shown), and a controller (not shown). The power supply assembly 200 is used to power the atomizer 100 and control the atomizer 100 to work so that the atomizer 100 can atomize the aerosol-generating matrix to form an aerosol; the airflow sensor is used to detect the airflow change in the electronic atomization device 300, and the controller starts the electronic atomization device 300 according to the airflow change detected by the airflow sensor. The atomizer 100 and the power supply assembly 200 can be set as an integral unit, for example, sharing a housing; or they can be detachably connected and designed according to specific needs. Of course, the electronic atomization device 300 also includes other components in the existing electronic atomization device 300, 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.

[0053] Specifically, the atomizer 100 includes a housing 1, an air pump 2, an atomizing nozzle 3 and a liquid storage bottle 4, wherein the housing 1 has an installation space 11, and the atomizing nozzle 3 is received in the installation space 11. The air pump 2 and the liquid storage bottle 4 can be received in the installation space 11, or can be arranged outside the installation space 11, depending on the actual situation. Figure 2 As shown, in this embodiment, the air pump 2 and the liquid storage bottle 4 are both arranged in the installation space 11 of the housing 1. The liquid storage bottle 4 serves as a liquid storage chamber for storing the aerosol generating substrate. The air pump 2 and the liquid storage bottle 4 are both in fluid communication with the atomizing nozzle 3. The air pump 2 is used to provide a high-speed airflow to the atomizing nozzle 3, and the liquid storage bottle 4 is used to provide the aerosol generating substrate to the atomizing nozzle 3, so that the aerosol generating substrate is atomized in the atomizing nozzle 3 under the action of the high-speed airflow to generate an aerosol and is ejected out of the atomizing nozzle 3.

[0054] Furthermore, in the present embodiment, the atomizer 100 further includes a heating element 5, which is disposed on one side of the mist outlet 31 of the atomizing nozzle 3. The aerosol is sprayed onto the heating element 5 through the mist outlet 31 of the atomizing nozzle 3. The heating element 5 is used to perform secondary heating and atomization on the aerosol, so that the aerosol is fully heated and atomized for the second time, the aerosol particle size is smaller, and the atomization efficiency is higher. In the present embodiment, the heating element 5 is in the shape of a hollow cylinder, and the aerosol at the mist outlet 31 of the atomizing nozzle 3 is sprayed out in the shape of a hollow cone, so that the aerosol at the mist outlet 31 of the atomizing nozzle 3 is sprayed more onto the inner side wall of the heating element 5 and is heated for the second time, thereby avoiding the problem that when the aerosol is sprayed in the shape of a solid cone, most of the aerosol does not contact and heat with the inner side wall of the heating element 5 but flows out directly through the internal channel of the heating element 5, thereby affecting the atomization efficiency. The atomization efficiency is improved while also meeting the requirements of hollow cone atomization.

[0055] In other embodiments, the heating element 5 may also be set to other shapes. For example, the heating element 5 may be set to a flat plate, mesh or other structure, as long as the heating element 5 can reheat and atomize the aerosol sprayed from the mist outlet 31 of the atomizing nozzle 3; alternatively, the heating element 5 may not be set, and the aerosol is directly sprayed out of the atomizer 100 through the mist outlet 31 of the atomizing nozzle 3 without secondary heating and atomization by the heating element 5.

[0057] See also Figure 3 and Figure 4 The atomizing nozzle 3 includes an atomizing chamber 32, and the side wall of the atomizing chamber 32 is provided with a plurality of first fluid inlets 33 spaced apart from each other, and the bottom wall of the atomizing chamber 32 is provided with an annular second fluid inlet 34, and the second fluid inlet 34 is used to transfer the second fluid to the atomizing chamber 32, and make the second fluid form a hollow body. Among them, the hollow body formed by the second fluid can be a hollow columnar body, for example, a hollow cylinder; it can also be a hollow cone directly, for example, a hollow cone; or it can also be a hollow body of other shapes. The first fluid inlet 33 is used to transfer the first fluid to the atomizing chamber 32, and make the first fluid and the second fluid atomized in the atomizing chamber 32 to generate an aerosol, and the top wall of the atomizing chamber 32 also has a mist outlet 31, and the mist outlet 31 is used to spray the aerosol out of the atomizing chamber 32. It can be understood that by setting the second fluid inlet 34 as an annular structure and making the second fluid form a hollow body, the aerosol ejected from the mist outlet 31 of the atomizing nozzle 3 can be in the form of a hollow cone-shaped atomizing cone, which meets the requirements of the hollow cone atomization function of the product, effectively solves the problem that the atomizing nozzle in the prior art cannot meet the hollow cone atomization requirements, and improves the atomization performance.

[0058] Specifically, the atomizing nozzle 3 includes a base 35 and a cover 36. The base 35 has a first surface 351. The first surface 351 is provided with an atomizing groove 352. The side wall of the atomizing groove 352 is provided with a plurality of first fluid grooves 353. The plurality of first fluid grooves 353 are distributed at intervals along the circumference of the side wall of the atomizing groove 352. The second fluid inlet 34 is provided at the bottom wall of the atomizing groove 352. The cover 36 covers one side of the first surface 351 of the base 35. The cover 36 cooperates with the atomizing groove 352 to form the atomizing chamber 32, and cooperates with the first fluid groove 353 on the first surface 351 to form the first fluid inlet 33. The first fluid inlet 33 is used to transfer one of the aerosol generating substrate and the airflow to the atomizing chamber 32, and the second fluid inlet 34 is used to transfer the other of the aerosol generating substrate and the airflow to the atomizing chamber 32. That is to say, the first fluid can be one of the aerosol generating substrate or the airflow, and the second fluid can also be the other of the aerosol generating substrate or the airflow. The cover body 36 is provided with a mist outlet 31 at a position corresponding to the atomization groove 352 . In this embodiment, the mist outlet 31 is a through hole penetrating the cover body 36 .

[0059] See also Figure 5 , Figure 6 , Figure 7 and Figure 8In one embodiment, the bottom wall of the atomizing groove 352 is provided with a plurality of through holes 342, and the plurality of through holes 342 are arranged at intervals from each other and arranged around the central axis of the atomizing chamber 32 to serve as the second fluid inlet 34. That is, the second fluid inlet 34 is formed by a plurality of through holes 342 spaced from each other, so that the second fluid transmitted to the atomizing chamber 32 by the second fluid inlet 34 forms a hollow body, and then the aerosol generated by atomizing the second fluid and the first fluid in the atomizing chamber 32 is in a hollow cone shape when ejected from the atomizing chamber 32 from the mist outlet 31, so as to meet the requirements of the hollow cone atomization function and improve the atomization performance. Preferably, the plurality of through holes 342 are evenly distributed along the circumference of the atomizing chamber 32, so that the hollow body formed by the second fluid transmitted to the atomizing chamber 32 by the second fluid inlet 34 can be more uniform, the first fluid and the second fluid can be more evenly mixed, and the atomization effect is better. In this embodiment, the extension direction of the through hole 342 is parallel to the central axis of the atomizing chamber 32 , and the through hole 342 is a straight hole, so that the second fluid transmitted from the second fluid inlet 34 to the atomizing chamber 32 forms a cylindrical hollow body.

[0060] In other embodiments, the extension direction of the through hole 342 may also have a certain angle with the central axis of the atomizing chamber 32, that is, the through hole 342 is an inclined hole arranged obliquely, and a plurality of through holes 342 are arranged at intervals from each other and arranged around the central axis of the atomizing chamber 32 to serve as the second fluid inlet 34, so that the second fluid transmitted to the atomizing chamber 32 via the second fluid inlet 34 directly forms a conical hollow body, and is atomized in the atomizing chamber 32 to form an aerosol and then ejected out of the atomizing chamber 32 in a hollow cone. Alternatively, the second fluid transmitted to the atomizing chamber 32 by the second fluid inlet 34 may also form a hollow body of any shape such as a prism or a pyramid. It can be understood that when the hollow body formed by the second fluid is cylindrical or conical, it is more conducive to uniform mixing with the first fluid, so that the atomization is more uniform and the effect is better.

[0061] like Figure 7 As shown, in a specific embodiment, the shape of the through hole 342 is circular, and a plurality of circular through holes 342 are arranged at intervals and surround the central axis of the atomizing chamber 32 to form a ring. The circular through holes 342 can make the atomization effect better. In this embodiment, the number of through holes 342 is equal to the number of first fluid grooves 353, and a plurality of through holes 342 are arranged one by one with a plurality of first fluid grooves 353, so that the atomization effect is more uniform and the hollow cone atomization effect is better. In other embodiments, the number of through holes 342 may also be different from the number of first fluid grooves 353, as long as a plurality of through holes 342 can be arranged to form a ring-shaped second fluid inlet 34.

[0062] like Figure 8As shown, in another specific embodiment, the through hole 342 is set to an arc shape, and a plurality of arc-shaped through holes 342 surround the central axis of the atomizing chamber 32 to form a circular ring-shaped second fluid inlet 34. Specifically, for example, the number of arcs can be two, the arcs of the two arcs are 180 degrees, and the two arc-shaped through holes 342 are spaced apart from each other and surround to form a circular ring; or, the number of arcs can be three, the arcs of the three arcs are 120 degrees, and the three arc-shaped through holes 342 are spaced apart from each other and surround to form a circular ring-shaped second fluid inlet 34. In other embodiments, the number of arc-shaped through holes 342 can also be set to other numbers, for example, any number such as four, five, six, etc., and the arc of the arc can be other degrees, as long as the plurality of arc-shaped through holes 342 can be surrounded to form a ring, so as to form a circular second fluid inlet 34, and the second fluid transmitted from the second fluid inlet 34 to the atomizing chamber 32 forms a hollow body. The shape of the through hole 342 can also be set to any shape such as rhombus, triangle, rectangle, etc., and a plurality of through holes 342 surround the central axis of the atomization chamber 32 to form a ring-shaped second fluid inlet 34 .

[0063] See also Fig. 9 and Fig.10 In another embodiment, the bottom wall of the atomizing groove 352 is provided with an annular through hole 341, which is arranged around the central axis of the atomizing chamber 32 and serves as the second fluid inlet 34. It should be noted that the annular through hole 341 refers to an arc with an arc greater than 300 degrees, that is, the annular shape can be a closed annular shape or an open arc with an arc greater than 300 degrees. Fig.10 As shown, the annular through hole 341 is an open arc. It can be understood that by setting the annular through hole 341 to an arc with an arc greater than 300 degrees, the second fluid transmitted from the second fluid inlet 34 to the atomizing chamber 32 can form a hollow columnar body, so that the aerosol generated by the atomization of the second fluid and the first fluid in the atomizing chamber 32 is a hollow cone when it is ejected from the atomizing chamber 32 from the mist outlet 31, so as to meet the needs of the hollow cone atomization function and improve the atomization performance. In other embodiments, the shape of the annular through hole 341 can be a circular ring or a rectangular ring, a diamond ring or other shapes. It can be understood that the circular annular through hole 341 can make the first fluid and the second fluid mixed more evenly in the atomizing chamber 32, with better atomization effect and higher efficiency.

[0064] See also Figure 5 , Figure 6 , Fig. 9 and Fig.11In this embodiment, the shape of the atomizing groove 352 is circular, and the mist outlet 31 is a circular through hole arranged corresponding to the atomizing groove 352. The shapes of the multiple first fluid grooves 353 on the first surface 351 of the substrate 35 are the same, and the multiple first fluid grooves 353 are evenly distributed along the circumference of the side wall of the atomizing groove 352. In this embodiment, the width of the first fluid groove 353 gradually decreases from one end of the first fluid groove 353 away from the atomizing groove 352 to one end close to the atomizing groove 352. In other embodiments, the width of the first fluid groove 353 may also remain unchanged from one end of the first fluid groove 353 away from the atomizing groove 352 to one end close to the atomizing groove 352. The number of the first fluid grooves 353 can be any number such as three, four, or six.

[0065] Specifically, Figure 5 and Fig. 9 As shown, in one embodiment, the side wall of the first fluid groove 353 is arc-shaped. Preferably, both side walls of the first fluid groove 353 are arc-shaped. The shapes of the multiple first fluid grooves 353 are the same and the multiple arc-shaped first fluid grooves 353 rotate in the same direction so that the multiple first fluid grooves 353 form a swirl structure. For example, the multiple arc-shaped first fluid grooves 353 rotate in a clockwise direction to form a swirl structure, or the multiple arc-shaped first fluid grooves 353 rotate in a counterclockwise direction to form a swirl structure. The first fluid groove 353 with a swirl structure makes the centrifugal force when the first fluid passes through the first fluid groove 353 intensify the pneumatic cutting atomization between the first fluid and the second fluid, improve the atomization effect of the high-viscosity medium, and is more conducive to forming a hollow cone-shaped aerosol.

[0066] like Figure 6 As shown, in another embodiment, the side wall of the first fluid groove 353 can also be set to be linear, the first fluid groove 353 is a linear structure, and multiple first fluid grooves 353 are evenly spaced along the circumference of the side wall of the atomization groove 352. In this embodiment, the width of the first fluid groove 353 gradually decreases from one end of the first fluid groove 353 away from the atomization groove 352 to the end close to the atomization groove 352. In other embodiments, the width of the first fluid groove 353 can also remain unchanged.

[0067] Further, in the present embodiment, the first surface 351 of the base 35 is further provided with a first guide groove 354, the first guide groove 354 surrounds the atomizing groove 352 and is spaced apart from the atomizing groove 352, the first fluid groove 353 is provided between the atomizing groove 352 and the first guide groove 354, specifically, the first fluid groove 353 is provided on the common side wall of the atomizing groove 352 and the first guide groove 354, a plurality of first fluid grooves 353 are all connected to the first guide groove 354, and the atomizing groove 352 and the first guide groove 354 are connected through the first fluid groove 353. In the present embodiment, the first guide groove 354 is annular. The cover body 36 cooperates with the first guide groove 354 to form a first guide channel 37. The outer wall of the first flow guide groove 354 is provided with a notch extending to the edge of the first surface 351, and the cover body 36 cooperates with the notch to form a first interface 355, and the first interface 355 is used to connect to an external pipeline to receive the first fluid.
