[0038] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0039] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0040] like Figures 1 to 3 As shown, this application provides an atomizer 1, which can heat and atomize the atomizing medium after being powered on, for user use.

[0041] The atomizer 1 includes a housing 10, a separator 20, a liquid guide 30, and an atomizing assembly 40. The separator 20 is disposed within the housing 10, and together with the housing 10, defines a liquid storage chamber 100 for storing the atomizing medium. The atomizing assembly 40, after being connected to a power source, atomizes the atomizing medium conducted to its surroundings to generate an aerosol for user use.

[0042] A liquid guiding element 30 is disposed within the housing 10, and together with the partition 20, defines a liquid guiding channel 300. The inlet end of the liquid guiding channel 300 is connected to the liquid storage chamber 100, and is used to guide the atomizing medium in the liquid storage chamber 100 to the atomizing assembly 40, so that the atomizing assembly 40 atomizes it. At least a portion of the channel wall of the liquid guiding channel 300 is curved or bent to slow down the flow rate of the atomizing medium and avoid leakage.

[0043] It should be understood that this atomizer 1 can be applied to fields such as medical treatment, beauty, health care, and e-cigarettes, without being specifically limited here. The atomizing medium can be in liquid form such as medicine or oil, and may also include media with functions such as enhancing flavor, without being specifically limited here.

[0044] This application, by setting up a liquid guiding component 30 and constructing a liquid guiding channel 300 with at least a portion of the channel wall in a curved or bent shape, can increase the flow resistance through the curvature or bend of the channel wall, thereby slowing down the liquid guiding rate and making the liquid guiding rate less than the atomization rate of the atomizing component 40 on the atomizing medium, thus avoiding the occurrence of liquid leakage problems.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the housing 10 is a flat, hollow cylindrical shape, including a main housing 11 and a nozzle portion 12 disposed on the main housing 11. A separator 20, a liquid guide 30, and an atomizing assembly 40 are disposed within the main housing 11. The nozzle portion 12 defines an air passage 121. This air passage 121 can communicate with the atomization channel 400 defined by the atomizing assembly 400 for supplying aerosol output for user use.

[0046] Specifically, the shell 10 can be in various columnar shapes such as cylindrical, elliptical, polygonal, or irregular, without any specific limitation. Of course, the shell 10 can also be in other shapes such as ellipsoidal, hemispherical, spherical, polygonal, or irregular.

[0047] Furthermore, an air inlet (not shown) may be defined on the main housing 11, which can be connected to the end of the atomizing channel 400 away from the air passage 121, so as to form an airflow channel that runs through the atomizing channel 400 and the air passage 121, so that gas can enter the atomizer 1 from the outside and flow out together with the aerosol in the atomizing channel 400.

[0048] In some embodiments, the mouthpiece 12 may be in the shape of a mouthpiece to facilitate the user's inhalation of the aerosol.

[0049] It should be understood that the nozzle part 12 and the main housing 11 can be connected and assembled detachably or non-detachably through various connection methods such as integral molding, welding, glue connection, snap connection, threaded connection, bolt connection, interference fit, etc., without specific limitations.

[0050] The main housing 11 can be integrally formed from a single component, or it can be assembled from at least two components in a detachable or non-detachable manner using various connection methods such as welding, glue connection, snap-fit ​​connection, threaded connection, bolt connection, interference fit, etc. No specific limitation is made here.

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the separator 20 is disposed within the housing 10 and further defines an atomizing chamber 21 and at least one liquid guiding chamber 22. An atomizing assembly 40 is disposed within the atomizing chamber 21. A liquid guiding member 30 is disposed within the liquid guiding chamber 22 and, together with the chamber wall of the liquid guiding chamber 22, defines a liquid guiding channel 300. The liquid guiding chamber 22 is located on the periphery of the atomizing chamber 21, and the liquid storage chamber 100 is located at one end of the atomizing chamber 21.

[0052] The liquid inlet of the liquid channel 300 is connected to the liquid storage chamber 100, and one side is connected to the atomizing chamber 21 through the liquid guide hole 23, so that the atomizing medium in the liquid storage chamber 100 can be guided to the atomizing component 40 in the atomizing chamber 21.

[0053] Specifically, the atomizing chamber 21 and the liquid guiding chamber 22 are located at the end of the liquid storage chamber 100 away from the nozzle portion 12, with the liquid guiding chamber 22 located on one side of the atomizing chamber 21. The separator 20 also defines at least one liquid guiding hole 23, which extends through the partition wall between the liquid guiding chamber 22 and the atomizing chamber 21 to connect the liquid guiding chamber 22 and the atomizing chamber 21. The liquid guiding channel 300 communicates with the atomizing chamber 21 through the liquid guiding hole 23.

[0054] like Figure 2 As shown, by using the atomizer 1 at this angle, the horizontal position of the nozzle 12 can be higher than the horizontal position of the liquid reservoir 100. The horizontal position of the liquid reservoir 100 is higher than the horizontal positions of the atomizing chamber 21 and the guiding chamber 22, so that the atomizing medium can be guided from the liquid reservoir 100 to the guiding chamber 22 under the action of gravity. The horizontal position of the guiding chamber 22 can be flush with the horizontal position of the atomizing chamber 21 to further slow down the flow speed of the atomizing medium and prevent leakage.

[0055] In some other embodiments, the nozzle portion 12 may not be located on the side of the liquid storage chamber 100 away from the liquid guiding chamber 22, but may be located at any other position on the main housing 11. Of course, when the atomizer 1 is in use, the horizontal position of the atomizing chamber 21 may also be lower than the horizontal position of the liquid guiding chamber 22.

[0056] like Figure 4 and Figure 5 As shown, in some embodiments, the separator 20 may include a first support 201 and a second support 202. The first support 201 defines a first tank 2011, the opening of which faces the liquid storage chamber 100. The second support 202 includes at least one extension 2021 that extends into the first tank 2011, defining the atomizing chamber 21 together with the tank wall of the first tank 2011.

[0057] Specifically, the second support 202 can be located between the first support 201 and the liquid storage chamber 100 along the axial direction of the atomizer 1, and the housing 100 and the second support 202 together define the liquid storage chamber 100. The nozzle portion 12 extends axially toward the second support 202 to form the airway tube 121.

[0058] Furthermore, the extension 2021 also defines a second tank 2022, namely a liquid guiding chamber 22 connected to the liquid storage chamber 100. The liquid guiding hole 23 is formed on the extension 2021 so that one side of the liquid guiding chamber 22 is connected to the atomizing chamber 21.

[0059] This configuration facilitates the production and assembly of the separator 20, improving efficiency and reducing costs.

[0060] Of course, the separator 20 can also be made from a single component through integral molding.

[0061] It should be understood that the first bracket 201 and the second bracket 202 can be assembled in a detachable or non-detachable manner through various connection methods such as welding, glue connection, snap connection, threaded connection, bolt connection, interference fit, etc., without specific limitations.

[0062] It should be understood that the outer periphery of the separator 20 may be provided with at least one sealing structure, or fitted with at least one sealing ring, to make an interference fit with the inner wall surface of the housing 10, so as to ensure the relative sealing of the liquid storage chamber 100 and prevent leakage.

[0063] In some other embodiments, the separator 20 may define only the atomizing chamber 21, and the liquid guiding member 30 may be disposed on the side of the separator 20 away from the liquid storage chamber 100, and together with the chamber wall of the atomizing chamber 21, define the liquid guiding channel 300. In this embodiment, the liquid guiding channel 300 and the liquid storage chamber 100 can be connected by providing a through hole in the separator 20.

[0064] Alternatively, when the separator 20 only defines the atomizing chamber 21, the liquid guiding member 30 can also be disposed within the liquid storage chamber 100, and together with the wall surface of the separator 20 facing the liquid storage chamber 100, define the liquid guiding channel 300. In this embodiment, a through hole can be provided in the separator 20 to allow the liquid guiding channel 300 to communicate with the liquid guiding of the atomizing chamber 21.

[0065] Continue reading Figure 2 and Figure 3In some embodiments, there are two liquid guiding chambers 22 and two extensions 2021, symmetrically arranged on opposite sides of the atomizing chamber 21. There are also two liquid guiding elements 30, each disposed within one of the two liquid guiding chambers 22, defining two liquid guiding channels 300. There are at least two liquid guiding holes 23. The two liquid guiding channels 300 controllably guide liquid from opposite sides of the atomizing chamber 21 through the liquid guiding holes 23 to the atomizing assembly 40 within the atomizing chamber 21, thereby improving the uniformity of atomization by the atomizing assembly 40.

[0066] It should be understood that the liquid guiding chamber 22 and the atomizing chamber 21 can be various columnar chambers such as cylindrical, polygonal, elliptical, and irregular columnar, or other shapes such as polygonal, elliptical, irregular, spherical, flat sheet, and various disc shapes. No specific limitation is made here.

[0067] In other embodiments, the number of liquid guiding chambers 22 and extensions 2021 may be three, four, five, or other plurality of units, and the number of liquid guiding components 30 may be correspondingly set to three, four, five, or other plurality of units. Multiple liquid guiding chambers 22 may be arranged at circumferential intervals along the atomization chamber 21 to uniformly guide liquid to the atomization assembly 40 within the atomization chamber 21 in the circumferential direction.

[0068] In some other embodiments, when there are multiple liquid guiding chambers 22, the liquid guiding chamber 22 may also be configured as an annular cylindrical shape, and the liquid guiding component 30 may also be configured as an annular column shape. The liquid guiding holes 23 may be arranged at intervals along the circumference of the atomizing chamber 21 to uniformly guide liquid to the atomizing component 40 in the atomizing chamber 21 in the circumference.

[0069] Continue reading Figure 2 and Figure 3 In some embodiments, the liquid guiding chamber 22 is open at one end near the liquid storage chamber 100, so that the liquid guiding chamber 22 is connected to the liquid storage chamber 100. The liquid guiding component 30 can be filled or fixed in the liquid guiding chamber 22, so as to define the liquid guiding channel 300 with the chamber wall of the liquid guiding chamber 22, and ensure that the atomizing medium in the liquid storage chamber 100 is guided to the atomizing component 40 in the atomizing chamber 21 through the liquid guiding channel 300. The atomizing chamber 21 can be connected to the airway tube 121, so that after the atomizing component 40 is assembled into the atomizing chamber 21, the defined atomizing channel 400 is connected to the airway tube 121.

[0070] In some other embodiments, the separator 20 may also be provided with a through hole to connect the liquid guiding chamber 22 with the liquid storage chamber 100, and to allow the liquid guiding channel 300 to connect with the liquid storage chamber 100 through the through hole when the liquid guiding member 30 is disposed in the liquid guiding chamber 22.

[0071] In some embodiments, the end of the extension 2021 of the second support 202 is spaced apart from the bottom wall of the first groove 2011 of the first support 201 to form a clearance area 203. The end of the liquid guiding chamber 22 away from the liquid storage chamber 100 can communicate with the end of the atomizing chamber 21 away from the liquid storage chamber 100 through the clearance area 203, so that the end of the liquid guiding channel 300 away from the liquid storage chamber 100 can communicate with the atomizing chamber 21 through the clearance area 203.

[0072] This configuration, combined with the positional relationship between the liquid storage chamber 100, the atomizing chamber 21, and the liquid guiding chamber 22, allows some of the atomizing medium to be guided to the atomizing chamber 21 through the liquid guiding hole 23 during user operation. The remaining atomizing medium can also be guided to the atomizing chamber 21 through the end of the liquid guiding chamber 22 away from the liquid storage chamber 100, thus achieving the diversion and conduction of the atomizing medium. This avoids the accumulation of the atomizing medium in the liquid guiding chamber 22, controls the liquid guiding speed, and ensures the smoothness of the liquid guiding.

[0073] In some other embodiments, when the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 is connected to the end of the atomizing chamber 21 away from the liquid storage chamber 100, the separator 20 may not be provided with a liquid guiding hole 23, so that the liquid guiding channel 300 is connected to the atomizing chamber 21 only through the end of the liquid guiding chamber 22 that is connected to the atomizing chamber 21.

[0074] In some other embodiments, the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 may also be separated from the clearance area 203. By providing a through hole at the position corresponding to the liquid guiding channel 300 in the extension 2021, only the end of the liquid guiding channel 300 away from the liquid storage chamber 100 is connected to the atomizing chamber 21 through the clearance area 203.

[0075] Of course, when the separator 20 is provided with a liquid guiding hole 23, the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 can also be separated from the end of the atomizing chamber 21 away from the liquid storage chamber 100, so that the liquid guiding channel 300 catties can be connected to the atomizing chamber 21 through the liquid guiding hole 23.

[0076] Continue reading Figure 2 and Figure 3 In some embodiments, the number of liquid guiding holes 23 may be multiple, such as three, four, or five. Multiple liquid guiding holes 23 are spaced apart along the extending direction of the liquid guiding channel 300.

[0077] Specifically, the liquid guiding channel 300 extends approximately along an axial direction parallel to the atomizing chamber 21 and the liquid guiding chamber 22, from one end of the liquid guiding chamber 22 near the liquid storage chamber 100 to the other end of the liquid guiding chamber 22 away from the liquid storage chamber 100. The liquid guiding holes 23 are spaced apart on the connecting wall between the atomizing chamber 21 and the liquid guiding chamber 22 along a direction parallel to the axial direction of the atomizing chamber 21 and the liquid guiding chamber 22.

[0078] When the atomizing component 40 is arranged coaxially in the atomizing chamber 21 in a longitudinal manner, the multiple liquid guiding holes 23 arranged at intervals along the liquid guiding channel 300 can uniformly guide the atomizing medium along the axial direction of the atomizing component 40, thereby improving the uniformity of atomization of the atomizing component 40.

[0079] Of course, when the axial dimension of the atomizing component 40 is small, or when the shape of the atomizing component 40 is such that it is located only at a certain position in the axial direction of the atomizing chamber 21, the number of liquid guiding holes 23 can also be set to one or two, etc.

[0080] It should be understood that the liquid guiding hole 23 can be a circular, polygonal, irregular, or other shapes. The diameter of the liquid guiding hole 23 can also be flexibly adjusted according to the atomization speed of the atomizing component 40, the liquid guiding capacity of the liquid guiding channel 300, the viscosity of the atomizing medium, etc., and is not specifically limited here.

[0081] like Figure 6 As shown, in some embodiments, the liquid guiding member 30 may include a main body 31 and at least one diversion structure 32. The outer wall of the main body 31 is recessed inward to form a groove. The groove generally extends from the end of the liquid guiding member 30 near the liquid storage chamber 100 to the end away from the liquid storage chamber 100, and at least part of the groove wall is curved or bent. The diversion structure 32 is disposed in the groove and, together with the groove wall, defines a liquid guiding groove 310. The groove wall of the liquid guiding groove 310 and the chamber wall of the liquid guiding chamber 22 together define the liquid guiding channel 300.

[0082] The diversion structure 32 divides the liquid guiding channel 300 into at least one main channel 301 and at least one return structure 302. The main channel 301 extends approximately along the axial direction of the liquid guiding member 30, with its inlet end penetrating the top wall of the member 30 to communicate with the liquid storage chamber 100. The end opposite the inlet end penetrates the bottom wall of the member 30 to communicate with the atomizing chamber 21 via the clearance area 203. Along the extension direction of the main channel 301, it can also communicate with the atomizing chamber 21 via a liquid guiding hole 23. The return structure 302 is located on one side of the main channel 301, with its inlet and outlet connected to the main channel 301, ensuring that the atomizing medium, after entering the return structure 302, is ultimately guided to the main channel 301.

[0083] It should be understood that the inlet can be understood as the port through which the atomizing medium enters the reflux structure 302, and the outlet can be understood as the port through which the atomizing medium flows out of the reflux structure 302. For example... Figure 7 As shown, the liquid inflow direction at the inlet of the reflux structure 302 is roughly opposite to the liquid outflow direction at the outlet.

[0084] By setting the diversion structure 32 to define the liquid guiding channel 300 as the main channel 301 and the return structure 302, the friction and local resistance of the liquid guiding channel 300 to the atomizing medium can be increased, thereby further reducing the flow rate of the atomizing medium. By restricting the liquid flow direction in the inlet and outlet of the return structure 302 to be opposite, the flow rate of the atomizing medium can be further reduced by the opposite liquid flow direction.

[0085] like Figure 6 As shown, in some embodiments, the body 31 may be a longitudinal columnar structure to accommodate the columnar liquid guiding chamber 22.

[0086] It should be understood that the dimensions of the main body 31 can be adapted to the dimensions of the liquid guiding chamber 22, and the two can even be interference-fitted to ensure that the atomizing medium is conducted to the atomizing chamber 21 only through the liquid guiding channel 300. Of course, if... Figure 2 As shown, there may also be a certain gap between the main body 31 and the chamber wall of the liquid guiding chamber 22, allowing a small amount of atomizing medium to fill the gap between them.

[0087] In some other embodiments, the shape of the main body 31 may be different from that of the liquid guiding chamber 22. For example, when the main body 31 is set as a semi-circular column, the liquid guiding chamber 22 may also be a rectangular column, etc.

[0088] In some other embodiments, the liquid guiding component 30 may also consist only of the main body 31, and by adjusting the size and shape of the liquid guiding groove 310 on the main body 31, it can achieve the effect of slowing down the flow rate of the atomizing medium.

[0089] like Figure 6 As shown, in some embodiments, the liquid guiding member 30 may further include at least two seals 33, which are spaced apart axially along the liquid guiding chamber 22. Each seal 33 is radially interference-fitted between the body 31 and the chamber wall of the liquid guiding chamber 22 to reduce leakage of the atomizing medium from the storage chamber 100 to the liquid guiding chamber 22. The seal 33 also extends circumferentially along the body 31 and terminates at the liquid guiding groove 310 to ensure that the atomizing medium is conducted within the liquid guiding channel 300 as much as possible.

[0090] It should be understood that the seal 33 can be made of materials with certain elasticity and stable material properties, such as silicone or rubber, and no specific limitation is made here.

[0091] The sealing element 33 can be a sealing structure that is separate from the main body 31, such as a sealing ring or a sealing gasket. It can also be fixed to the main body 31 by means of adhesive bonding, integral molding, etc., and no specific limitation is made here.

[0092] In some other embodiments, the main body 31 can also be made of materials with certain elastic properties such as silicone or rubber, and be filled into the liquid guiding chamber 22 by interference, so that the chamber wall of the liquid guiding chamber 22 closes the groove end of the liquid guiding groove 310, defining a relatively sealed liquid guiding channel 300, so as to achieve a sealing effect while guiding liquid.

[0093] like Figure 2 and Figure 6 As shown, in some embodiments, the liquid guiding groove 310 is located on the side wall of the main body 31 and is disposed toward the liquid guiding hole 23 so as to communicate with the liquid guiding hole 23 for liquid guiding.

[0094] At least a portion of the wall of the liquid guiding groove 310 may be in various shapes such as S-shaped, U-shaped, Z-shaped, C-shaped, irregularly curved or bent, so that at least a portion of the groove section of the liquid guiding groove 310 is in various shapes such as S-shaped, U-shaped, Z-shaped, C-shaped, irregularly curved or bent groove wall.

[0095] By setting a liquid guiding groove 310 on the liquid guiding component 30, which cooperates with the chamber wall of the liquid guiding chamber 22 to form a liquid guiding channel 300, the production and assembly of the liquid guiding component 30 and the liquid guiding channel 300 can be facilitated. At the same time, it is easy to achieve the relative sealing of the liquid guiding channel 300 and avoid leakage.

[0096] By providing a curved or bent portion on the liquid guiding groove 310, the flow rate of the atomizing medium can be reduced when it flows under gravity, thereby preventing the supply speed of the atomizing medium from exceeding the atomization speed of the atomizing component 40 and causing leakage.

[0097] It should be understood that the width and depth of the liquid guiding groove 310 can be flexibly adjusted according to various factors such as the atomization speed of the atomizing component 40, the capacity of the liquid storage chamber 100, and the viscosity of the atomizing medium, and are not specifically limited here.

[0098] Furthermore, both ends of the liquid guiding groove 310 are through-holes in the extending direction, making it a through-groove shape with both ends through-holes in the extending direction. The end near the liquid storage chamber 100 is through-hole, allowing the atomizing medium in the liquid storage chamber 100 to automatically flow to the liquid guiding channel 300 under gravity through this through-hole end and the through-hole end of the liquid guiding chamber 22 near the liquid storage chamber 100. The end away from the liquid storage chamber 100 is through-hole, allowing the atomizing medium discharged from the downstream end of the liquid guiding channel 300 to be conducted into the atomizing chamber 21 through the communication between the clearance area 203 and the end of the atomizing chamber 21 away from the liquid storage chamber 100.

[0099] In some other embodiments, when the atomizing chamber 21 and the liquid guiding chamber 22 are separated at their ends away from the liquid storage chamber 100, the end of the liquid guiding groove 310 corresponding to the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 can either penetrate the main body 31, making the liquid guiding groove 310 a through groove extending through both ends in the length direction, or the end can be non-penetrating the main body 31. Of course, when the atomizing chamber 21 and the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 are connected, the end of the liquid guiding groove 310 corresponding to the end of the liquid guiding chamber 22 away from the liquid storage chamber 100 can also be non-penetrating the main body 31.

[0100] See also Figure 7 In some embodiments, the liquid guiding groove 310 may include a plurality of groove portions 3100, each groove portion 3100 being connected end to end along the extension direction of the liquid guiding groove 310 to form a longitudinally elongated liquid guiding groove 310.

[0101] Specifically, the groove 3100 can be arranged in various shapes such as circular, polygonal, teardrop, elliptical, irregular, etc. Each groove 3100 can have at least part of its groove wall in an arc or bend shape to achieve a slow flow effect on the atomizing medium.

[0102] In some other embodiments, the liquid guiding channel 310 may also include at least two different channels 3100. For example, it may include at least one first channel and at least one second channel. The first channel and the second channel have different shapes and may be connected end to end alternately or irregularly to form a longitudinally elongated liquid guiding channel 310.

[0103] In some other embodiments, the number of the groove 3100 may be set to one or two, and the number can be flexibly adjusted according to the shape and size of the atomizing component 40, the number of liquid guiding holes 23, the required length of the liquid guiding channel 300, etc.

[0104] like Figure 6 and Figure 7 As shown, in some embodiments, the diversion structure 32 may be disposed within the channel 3100, dividing the channel 3100 into a first part 3101 and a second part 3102 connected end to end. The first parts 3101 of the multiple channels 3100 are connected end to end, collectively forming the main channel 301. The second parts 3102 of the multiple channels 3100 each form a return flow structure 302, with both ends connected to the main channel 301.

[0105] Specifically, the second part 3102 is curved or bent, and its length can be greater than the length of the first part 3101, so that the length of the return structure 302 is greater than the length of the main channel 301 segment between its two ends.

[0106] For example, in some embodiments, the reflux structure 302, along the extending direction of the liquid guide groove 310, has its tail end located between its head end and a portion of its intermediate section. That is, when the atomizer 1... Figure 2 When the angle is set as shown, the liquid guiding component 30 is at... Figure 7 As shown in the angle setting, the horizontal position of the tail end of the recirculation structure 302 is lower than the horizontal position of its head end, but higher than the horizontal position of part of the middle section.

[0107] For example Figure 7 As shown, the second part 3102 corresponds to the trench wall of the trench 3100, which can be approximately inclined in an L-shape or C-shape, so that the trench 3100 is approximately inclined in a triangle or teardrop shape.

[0108] By positioning the tail end of the reflux structure 302 along the extension direction of the liquid guiding groove 310 between its head end and part of its intermediate section, when the atomizer 1 is not in operation, some atomized medium is buffered at the lowest intermediate section of the reflux structure 302, achieving a certain liquid-locking effect and reducing the risk of leakage. Simultaneously, since the tail end of the reflux structure 302 is connected to the main flow channel 301, during the operation of the atomizer 1, the atomized medium will still be guided from the reflux structure 302 to the main flow channel 301 under inertia, without affecting the conduction of the atomized medium.

[0109] Of course, other embodiments are also possible, in which the tail end of the reflux structure 302 is located on the side of its intermediate section away from the head end along the extending direction of the liquid guide groove 310. That is, when the atomizer 1... Figure 2 When the angle shown is set, the horizontal position of its tail end is lower than the horizontal position of the middle section, and the horizontal position of the middle section is lower than the horizontal position of its head end. In this embodiment, the return structure 302 can be wavy, bent, arc-shaped, or other irregular shapes.

[0110] In some other embodiments, the diversion structure 32 may also be disposed at the position where two adjacent tank sections 3100 are connected. Alternatively, when the liquid guiding tank 310 includes other tank structures in addition to the tank section 3100, the diversion structure 32 may also be disposed at least partially within the other tank structure.

[0111] It should be understood that the main channel 301, formed by connecting multiple first parts 3101 end to end, can be arranged in a straight groove or in an irregular groove with slight bends or turns; no specific limitation is made here. The bend or turn angle of the main channel 301 can be smaller than the bend or turn angle of the branch section 311 to achieve a smooth flow guiding effect and avoid the liquid supply speed being too low, which would cause the atomizing component 40 to burn out.

[0112] like Figure 6 and Figure 7As shown, in some embodiments, when there are multiple diversion structures 32, their number can be set to correspond to the number of slots 3100, and each slot 3100 is provided with a diversion structure 32.

[0113] It should be understood that the shape of the diversion structure 32 can correspond to that of the groove 3100, for example, both can be polygonal. Alternatively, they can be different shapes, such as the diversion structure 32 being circular and the groove 3100 being polygonal.

[0114] Of course, the diversion structures 32 in each slot 3100 may be arranged with the same shape and / or size, or there may be at least one diversion structure 32 that is arranged with a different shape and / or size from the other diversion structures 32.

[0115] In some other embodiments, the number of the diversion structure 32 may be less than the number of the slots 3100, and may be disposed within a portion of the slots 3100.

[0116] Continue reading Figure 7 In some embodiments, when there are multiple diversion structures 32, the multiple return structures 302 formed by the return structures 302 can be alternately distributed on opposite sides of the main channel 301, so that the multiple return structures 302 are staggered along the axial direction of the liquid guide 30.

[0117] This design allows the atomizing medium to be distributed more evenly into each return structure 302 when it is conducted within the liquid guiding channel 300 under the action of gravity, thereby improving the effectiveness of the return structure 302.

[0118] It should be understood that multiple reflux structures 302 are alternately distributed on opposite sides of the main flow channel 301. This can be understood as the reflux structures 302 being arranged alternately on opposite sides of the main flow channel 301 with one number as the circulation unit, that is, the liquid guiding structure 300 is Tesla valve shaped. Alternatively, it can be understood that the reflux structures 302 are arranged alternately on opposite sides of the main flow channel 301 with at least two numbers as circulation units.

[0119] In other embodiments, the distribution of the return structures 302 on opposite sides of the main channel 301 may be non-uniform. For example, at the section of the main channel 301 near the beginning, each return structure 302 is alternately arranged on opposite sides of the main channel 301 with two units as circulation units; at the section of the main channel 301 near the end, each return structure 302 is alternately arranged on opposite sides of the main channel 301 with one unit as circulation units, and so on.

[0120] It should be understood that the diversion structure 32 can be detachably or non-detachably installed in the liquid guiding groove 310 through various connection methods such as integral forming, glue connection, snap connection, and threaded connection, without specific limitations here.

[0121] The location where the main flow channel 301 connects to the inlet of the return flow structure 302 is defined as the branch port. In some embodiments, the liquid guide hole 23 is correspondingly provided with the branch port of the main flow channel 301. It can also be understood that the liquid guide hole 23 can be located at the mutual communication position of two adjacent tank sections 3100.

[0122] Specifically, the liquid guiding holes 23 can be evenly spaced along the extension direction of the liquid guiding groove 310. For example, a liquid guiding hole 23 can be provided at each position where two grooves 3100 are connected. Alternatively, a liquid guiding hole 23 can be provided at each fixed interval between the positions where two grooves 3100 are connected.

[0123] Alternatively, the liquid guiding holes 23 may be arranged non-uniformly along the extension direction of the liquid guiding groove 310 according to the atomization requirements of the atomizing component 40, etc., without specific limitations here.

[0124] At this location, the tail end of the first part 3101 of the preceding groove 3100 and the tail end of the second part 3102 merge and connect, resulting in a relatively large flow rate at this location. This allows the atomizing medium to smoothly enter the atomizing chamber 21 from the liquid guiding hole 23, thereby slowing down the flow rate of the atomizing medium to avoid leakage and preventing the atomizing medium from flowing too slowly and causing a supply shortage. At the same time, this arrangement also ensures that most of the atomizing medium can enter the atomizing chamber 21 through each liquid guiding hole 23, thereby achieving uniform distribution in the axial position of the atomizing assembly 40. This prevents a large amount of atomizing medium from entering the atomizing chamber 21 through the connection between the end of the atomizing chamber 21 away from the liquid storage chamber 100 and the end of the liquid guiding chamber 22 away from the liquid storage chamber 100, which would cause the atomizing medium to accumulate at that end position.

[0125] Of course, the location of the liquid guide hole 23 can be flexibly adjusted based on the size of the liquid guide groove 310, the atomization speed of the atomizing component 40, the capacity of the liquid storage chamber 100, the viscosity of the atomizing medium, and the size of the first part 3101 and the second part 3102, and can correspond to any position of the main channel 301 or the return structure 302.

[0126] In some other embodiments, when the number of the liquid guide holes 23 is at least two, they may also correspond partly to the main flow channel 301 and partly to the reflux structure 302, etc.

[0127] In embodiments where the liquid guiding component 30 only includes the main body 31, the liquid guiding hole 23 can be flexibly positioned to correspond with the liquid guiding groove 310 based on the required liquid guiding speed. For example, it can be positioned at a location with a relatively large cross-sectional dimension of the liquid guiding groove 310, or at a location with a relatively small cross-sectional dimension of the liquid guiding groove 310.

[0128] It should be understood that the aforementioned beginning, end, and both ends can be defined according to the flow direction of the atomizing medium in the tank or channel. Taking the reflux structure 302 as an example, the end through which the atomizing medium first passes is its beginning, and the end through which it passes next is its end.

[0129] like Figure 2 As shown, in some embodiments, the atomizer may further include a liquid storage medium 50. The liquid storage medium 50 is arranged circumferentially along the atomizing assembly 40, serving to guide the atomizing medium and store it. The liquid guiding channel 300 is respectively connected to the channel defined by the liquid storage medium 50 through the clearance area 203 and the liquid guiding hole 23.

[0130] The liquid storage medium 50 is used to heat and atomize the surrounding atomizing medium after being energized. The liquid storage medium 50 has numerous capillary channels (not shown in the figure), which are interconnected and form channels within the liquid storage medium 50 to communicate with the liquid guiding channel 300, thereby conducting the atomizing medium to the surrounding area of ​​the atomizing component 40 for atomization.

[0131] Specifically, the liquid storage medium 50 can be in the form of a hollow cylinder, with its outer contour matching the inner contour of the atomizing chamber 21, and is filled into the atomizing chamber 21 with an interference fit, so as to facilitate the connection between the capillary channel and the liquid guiding channel 300.

[0132] The atomizing assembly 40 may include an atomizing element and a connecting electrode. The atomizing element may be sheet-like, spiral-shaped, or cylindrical, and is attached to the hollow inner wall of the liquid storage medium 50, extending to the outside of the housing 10 via the connecting electrode for electrical connection to an external power source. The atomizing channel 400 is located within the hollow liquid storage medium 50 and is defined by the liquid storage medium 50 and the atomizing element attached to its inner wall.

[0133] It is important to understand that the atomizing method of this atomizing component is not limited. For example, it can employ one or more of the following atomizing methods: resistance heating, electromagnetic heating, infrared heating, ultrasonic atomization, and plasma heating.

[0134] It should be understood that the material selection of the liquid storage medium 50 can depend on the physical properties of the atomizing medium. For example, it can be a porous material, including but not limited to cotton-like materials (such as natural cotton and / or synthetic cotton) or inorganic porous materials (such as ceramics, fiber materials, etc.). Liquid storage components made of different materials can be used to adapt to different physical properties of liquid matrices, such as density, viscosity, surface tension, and vapor pressure, so flexible selection is possible and no specific limitations are made here.

[0135] By setting up a liquid storage medium 50, it can utilize its numerous capillary channels to achieve stable conduction of the atomizing medium through capillary force. Simultaneously, when the atomizer 1 is not in operation, the liquid storage medium 50 can also absorb and store a portion of the atomizing medium to further reduce leakage.

[0136] In other embodiments, the liquid storage medium 50 may be configured in various shapes such as block, column, or irregular. The atomizing element may also be configured in various shapes such as filament, mesh, sheet, needle, column, or irregular. The atomizing element may be inserted into the liquid storage medium 50 or attached to at least a portion of the wall surface of the liquid storage medium 50.

[0137] In some other embodiments, the atomizing channel 400 may also be defined by the liquid storage medium 50, the atomizing component 40, and the chamber wall of the atomizing chamber 21.

[0138] This application also provides an electronic atomizing device, which may include the atomizer in any of the foregoing embodiments.

[0139] In some embodiments, the electronic atomizing device may further include a power supply component (not shown) that is electrically connected to the atomizing element in the atomizing assembly 40 via a connecting electrode to provide it with electrical power.

[0140] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
