The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The atomizer is used to heat the atomizing medium and atomize it to form an aerosol, and then use the air introduced from the outside to fully mix with the aerosol to form smoke for the user to inhale. In the related art, the atomizing channel of the atomizer is usually set in a straight form, such as Figure 1 As shown, Figure 1 This is a simulation diagram of the flow of aerosol in the atomization channel in a straight form. The color area in the figure represents the aerosol concentration, red represents high concentration, and blue represents low concentration. The atomization channel in a straight form has the following problems. First, there is a Coanda effect in the atomization channel. Most of the aerosol rises along the wall of the atomization channel. Due to the viscous resistance of the wall, the rising speed of the aerosol slows down, and due to the low temperature of the wall, the aerosol is prone to condensation, which will lead to aerosol loss and a decrease in concentration. The condensate will cause leakage during the use of the atomizer. Second, due to the miniaturized design of the atomizer, the space for mixing air and aerosol is limited, and the two are difficult to fully mix evenly, which reduces the user's taste experience.

[0031] Based on this, first of all, please refer to Figures 2 to 6 The present application provides a swirl assembly 30, which is used to be arranged in the atomization channel 10. The swirl assembly 30 includes a swirl generating member 31 and a first guide member 32. The swirl generating member 31 includes a first end 311 and a second end 312 that are arranged opposite to each other. The first guide member 32 is arranged at the first end 311. The swirl generating member 31 is provided with an air inlet channel 313. The air inlet channel 313 forms an air outlet 314 at the first end 311. The air outlet 314 is located outside the first guide member 32. The air inlet channel 313 is used to allow external gas to pass through the air outlet 314 to form a spiral airflow around the outer periphery of the first guide member 32 and flow along the axial direction. Please refer to Figure 5 , Figure 5 The simulation effect of the airflow after the swirl assembly 30 is set in the atomizing channel is shown. The swirl assembly 30 is used to form a spiral airflow. At the same time, the first guide 32 is set to guide the airflow to rotate around the outer surface of the first guide 32 and flow along the axial direction of the first guide 32, and guide the spiral airflow to gather at the axis of the atomizing channel 10. In this way, the spiral airflow remains in a gathered state without dispersion after leaving the surface of the first guide 32, thereby improving the degree of airflow concentration. On the one hand, the spiral airflow with a certain degree of concentration enables most of the airflow to flow at the axial position of the atomizing channel 10, and overcomes the influence of the viscous resistance of the inner wall of the atomizing channel 10, thereby taking the aerosol on the inner wall of the atomizing channel 10 away from the wall to avoid aerosol loss, and ensure that the aerosol airflow has a sufficient flow speed, ensuring that the user can obtain sufficient aerosol concentration and speed when using the atomizer 200; on the other hand, the spiral airflow can avoid the aerosol from contacting the inner wall of the atomizing channel 10 for a long time, thereby reducing the heat loss of the aerosol, avoiding the formation of condensate, and improving the convenience and reliability of the use of the atomizer 200.

[0032] Optionally, the air inlet channel 313 may form a spiral airflow in different ways, which will be described below respectively.

[0033] In the first example, see Figure 2 and Figure 3 The air inlet channel 313 penetrates the end surface of the second end 312 of the swirl generating member 31, and the air inlet channel 313 is inclined or spiral relative to the axis of the swirl generating member 31. In this way, the air inlet channel 313 is not parallel to the axis of the swirl generating member 31, so that the angle between the air inlet channel 313 and the axial direction of the spiral generating member can be used to make the gas have the initial velocity and direction of spiral flow when leaving the air inlet channel 313, so as to further form a spiral airflow under the guidance of the first guide member 32.

[0034] In the second example, see Figure 4 The first end 311 of the swirl generating member 31 is also provided with a groove 3111, and the groove 3111 is arranged around the outer periphery of the first guide member 32 to form a swirl chamber 3112. The air outlet 314 is opened on the side wall of the swirl chamber 3112 and communicates with the swirl chamber 3112. One end of the first guide member 32 is fixed in the swirl chamber 3112, and the other end protrudes out of the swirl chamber 3112. The air outlet direction of the air outlet 314 is tangent to the outer periphery of the first guide member 32. The swirl chamber 3112 is formed by setting the groove 3111. The airflow flowing out of the air outlet 314 can first form a swirl in the swirl chamber 3112 and have a certain speed, and then continue to further gather under the guiding action of the first guide member 32 to form a spiral airflow with a higher speed. In this way, a part of the space of the swirl generating member 31 can be borrowed and fully utilized to extend the generation path of the spiral airflow, so as to increase the speed and aggregation degree of the spiral airflow to the required level. The groove 3111 provided on the surface of the first end 311 can save space for the swirl generating member 31. The outlet direction of the air outlet 314 is tangent to the outer periphery of the first guide member 32, so that when the airflow enters the swirl chamber 3112 along the air inlet channel 313, the airflow will be subjected to asymmetric resistance and driving force on both sides of the airflow in the swirl chamber 3112, so that the airflow generates a rotational motion around the first guide member 32.

[0035] The following will further explain using the first example.

[0036] Please continue reading Figure 2 and Figure 3In some embodiments, the swirl generating member 31 is provided with a plurality of air inlet channels 313, the plurality of air inlet channels 313 are arranged at intervals around the axis of the swirl generating member 31, and a plurality of air outlets 314 are formed on the end surface of the first end 311, and the plurality of air outlets 314 are arranged at intervals around the periphery of the first guide member 32. By providing a plurality of air inlet channels 313, on the one hand, the air inlet area of ​​the swirl generating member 31 can be increased, thereby improving the air inlet efficiency, avoiding the airflow from gathering at the bottom of the swirl generating member 31 to cause condensation, and reducing the influence of the setting of the swirl generating member 31 on the aerosol flow. On the other hand, the plurality of air inlet channels 313 can make the gas more uniform when forming the spiral airflow. By providing the air outlets 314 around the periphery of the first guide member 32, the guiding function of the first guide member 32 can be fully utilized, so that the spiral airflow can flow around the first guide member 32 more evenly, thereby improving the airflow gathering effect.

[0037] In some embodiments, the swirl assembly 30 also includes a second guide member 33, which is disposed at the second end 312. The cross-section of the second guide member 33 gradually increases along the air supply direction. A plurality of air inlet channels 313 form a plurality of air inlets 315 on the end surface of the second end 312. The plurality of air inlets 315 are spaced around the outer periphery of the second guide member 33. The surface of the second guide member 33 is used to guide the airflow into the plurality of air inlets 315. By providing the second guide member 33, the airflow can be dispersed and guided to enter each air inlet 315 respectively, thereby increasing the speed at which the gas flows into each air inlet 315. Exemplarily, the surface of the second guide member 33 can be set to a spherical surface or a conical surface. Taking a spherical surface as an example (such as Figure 2 , 3 As shown in the figure, the second guide member 33 having a spherical surface can also reduce the gas accumulation on the surface of the second guide member 33 and shorten the gas residence time on the surface of the second guide member 33, thereby avoiding the formation of condensation of aerosol.

[0038] In some embodiments, the first guide 32 is coaxially arranged with the second guide 33. In this way, it is possible to ensure that the airflow has good coaxiality when entering and leaving the swirl assembly 30, and to ensure that the airflow has a good degree of aggregation. Further, when the swirl assembly 30 is arranged in the atomizing channel 10, the first guide 32 is coaxially arranged with the atomizing channel 10, that is, the first guide 32 and the second guide 33 are coaxially arranged with the atomizing channel 10. In this way, it is possible to ensure that the distance between each air inlet 315 and the inner wall surface of the atomizing channel 10 is the same, and the distance between each air outlet 314 and the inner wall surface of the atomizing channel 10 is the same, thereby ensuring that the axis of the formed spiral airflow is roughly coaxial with the axis of the atomizing channel 10, reducing the friction between the spiral airflow and the inner wall surface of the atomizing channel 10, and further reducing the effect of the viscous resistance of the inner wall surface of the atomizing channel 10 on the airflow.

[0039] Optionally, the second guide member 33 and the first guide member 32 can be integrally formed, and the two can be connected as one by a connecting section (not shown), a through hole is provided along the axis of the swirl generating member 31, the through hole passes through the first end 311 and the second end 312 of the swirl generating member 31, and the integral member formed by the first guide member 32 and the second guide member 33 is passed through and fixed in the through hole, the first guide member 32 protrudes from the first end 311, and the second guide member 33 protrudes from the second end 312. Of course, in other examples, the first guide member 32, the second guide member 33 and the swirl generating member 31 can be integrally formed.

[0040] In some embodiments, the cross-sectional area of ​​the first guide member 32 gradually decreases along the air supply direction. The first guide member 32 with a cross-sectional area gradually decreasing along the air supply direction can not only guide the airflow to flow along the outer periphery of the first guide member 32, but also along the direction of the airflow, thereby reducing the obstruction to the airflow and ensuring that the spiral airflow can maintain a sufficient spiral speed. Exemplarily, the first guide member 32 is set to be conical (such as Figure 2 As shown in FIG. 1 , the first guide member 32 having a conical surface can guide the airflow to quickly gather toward the top of the cone along its outer surface, thereby improving the gathering effect of the spiral airflow. Of course, in other examples, the first guide member 32 can also be set to a cylindrical shape (such as Figure 4 As shown), or the surface of the first guide surface 32 is set to be a spherical surface.

[0041] In a second aspect, the present application also provides an atomization assembly 100, see Figures 6 to 8The atomizer assembly 100 includes the swirl assembly 30 provided in the first aspect. The atomizer assembly 100 is provided with an atomizer channel 10 and an atomizer core 20 disposed in the atomizer channel 10. The atomizer core 20 is used to heat the atomization medium and atomize it to form an aerosol, so the atomizer core 20 includes a heating element 24, and the heating element 24 is used for heating by electricity. Accordingly, the heating element 24 is provided with a pin 241, and the pin 241 can extend out of the atomizer core 20 and is used to connect to a power source or a circuit board outside the atomizer core 20. In order to better fix the pin 241, in some embodiments, the swirl generating member 31 is further provided with a pin fixing groove 316, the pin fixing groove 316 passes through the first end 311 and the second end 312, and the pin fixing groove 316 and the air inlet channel 313 are not connected to each other, and the pin 241 extends from the air inlet side 21 of the atomizing core 20; when the swirl assembly 30 is arranged on the air inlet side 21 of the atomizing core 20, the pin 241 is penetrated in the pin fixing groove 316 and extends from the second end 312. After the pin 241 extends from the pin fixing groove 316, it can be connected to the circuit board or related circuits and the battery (not shown) located outside the atomizing channel 10, so that the energy provided by the battery is used for heating under the control of the circuit board, and the atomizing medium is heated and atomized. Using the pin fixing groove 316, on the one hand, it is not only convenient to fix the pin 241 of the heating element 24, but also to prevent the heating element 24 from loosening and shifting, and to prevent the heating element 24 from deforming, thereby improving the reliability of the atomizing assembly 100. Moreover, when fixing the pin 241, it is only necessary to insert the pin 241 into the pin fixing groove 316, which is simple to manufacture, reduces the difficulty of assembly, and improves assembly efficiency. On the other hand, by setting the pin fixing groove 316 on the swirl generating member 31, the pin 241 can be fixed without adding other fixing structures, reducing the parts design of the atomizing assembly 100 and simplifying the structure of the atomizing assembly 100.

[0042] In some embodiments, the outer peripheral surface of the swirl generating member 31 is provided with a plurality of pin fixing grooves 316 at intervals, and the plurality of pin fixing grooves 316 are arranged parallel to the axial direction of the swirl generating member 31. When assembling the atomizing assembly 100, the atomizing core 20 is usually installed in the atomizing channel 10 first, at which time the heating element 24 has been fixed to the oil guide body 25 of the atomizing core 20, and the position of the pin 241 of the heating element 24 in the atomizing channel 10 is usually fixed accordingly. Therefore, by providing a plurality of pin fixing grooves 316, on the one hand, no matter at which angle the swirl component 30 is assembled into the atomizing channel 10, the pin 241 can match any one of the plurality of pin fixing grooves 316, thereby reducing the difficulty of alignment between the pin 241 and the pin fixing groove 316, and improving the convenience and efficiency of assembly. On the other hand, compared with drilling a through hole in the swirl generating member 31, providing a groove on the outer peripheral surface of the swirl generating member 31 can reduce the difficulty of processing. That is, the pin fixing groove 316 and the inner wall surface of the atomizing channel 10 are mutually enclosed to form a through hole for accommodating the pin 241. The pin fixing groove 316 is arranged parallel to the axial direction of the swirl generating member 31, which can ensure that the pin 241 passing through the pin fixing groove 316 is also parallel to the axial direction of the swirl generating member 31, which can not only shorten the routing distance of the pin 241, but also improve the stability of the installation of the heating element 24.

[0043] It can be understood that the atomization channel 10 usually takes in air from the bottom, and the external air enters from the bottom of the atomization channel 10 and passes through the atomization core 20. The atomization core 20 heats the atomization medium and atomizes it to form an aerosol. The aerosol is mixed with the external air entering the atomization channel 10 to form smoke. The smoke is further transported through the atomization channel 10 until it reaches the user's mouth. The airflow flows in the atomization channel 10 roughly in a bottom-up manner. Figure 6 , 7 , 8, the direction indicated by the arrow is the air inlet direction. Therefore, the swirl assembly 30 is arranged in the atomization channel 10, which can guide the airflow flowing along a straight line in the atomization channel 10 to form a spiral airflow. Optionally, the swirl assembly 30 can be arranged at various positions of the atomization channel 10, such as the air inlet side and the air outlet side of the atomization core 20, or at the air inlet side 21 and the air outlet side 22 of the atomization core 20. The above-mentioned several settings of the swirl assembly 30 are described below:

[0044] In some examples, the swirl assembly 30 may be disposed on the air outlet side 22 of the atomizer core 20, that is, the swirl assembly 30 is located downstream of the atomizer core 20 along the air flow direction (eg, Figure 8 As shown), in this way, the swirl component 30 can guide the aerosol to form a spiral airflow, reduce the loss of aerosol on the inner wall of the atomization channel 10 due to the wall-adhering movement, and improve the taste of the user when using the atomizer 200.

[0045] In other examples, the swirl assembly 30 may also be disposed on the air inlet side 21 of the atomizer core 20, that is, the swirl assembly 30 is located upstream of the atomizer core 20 along the airflow direction (eg, Figure 7 As shown), in this way, the swirl component 30 can guide the air to form a spiral airflow before it enters the atomizer core 20. On the one hand, compared with the airflow moving in a straight line, the spiral airflow has a higher power to facilitate the full contact and mixing of the air and the aerosol, and improve the mixing effect of the aerosol without increasing the mixing space of the atomization channel 10. The smoke after the aerosol and the air are mixed can also have a certain spiral flow effect under the spiral power of the spiral airflow, thereby achieving the effect of reducing the viscous resistance of the inner wall of the atomization channel 10 that affects the aerosol flow rate; on the other hand, compared with setting the swirl component 30 on the air outlet side 22 of the atomizer core 20, the swirl component 30 located on the air inlet side 21 can reduce its own obstruction to the aerosol with larger particles, so that the aerosol flows more smoothly in the atomization channel 10. In some other examples, the atomization assembly 100 can also be provided with two swirl assemblies 30, and the two swirl assemblies 30 are respectively arranged on the air inlet side 21 and the air outlet side 22 of the atomization core 20, so that the aerosol can form a spiral airflow before the airflow enters the atomization core 20 and after leaving the atomization core 20.

[0046] In some embodiments, the atomizing core 20 is formed with an atomizing chamber 23, the atomizing chamber 23 is connected to the atomizing channel 10, the swirl assembly 30 is arranged on the air inlet side 21 of the atomizing core 20, and when the first guide 32 is set to be conical, the cone top of the first guide 32 faces the atomizing chamber 23, and the projection of the cone top of the first guide 32 along the axial direction of the first guide 32 is located in the atomizing chamber 23. By directing the cone top of the conical first guide 32 toward the atomizing chamber 23, the spiral airflow can be guided into the atomizing chamber 23, and by using the projection of the first guide 32 in the atomizing chamber 23, the alignment accuracy of the first guide 32 and the atomizing chamber 23 can be improved, the path of the spiral airflow entering the atomizing chamber 23 can be shortened, and the movement efficiency of the spiral airflow can be improved.

[0047] Third, see Figure 7 and Figure 8 The present application also provides an atomizer 200, which includes the atomizer assembly 100 provided in the second aspect. Of course, the atomizer 200 may also include a housing 201, a nozzle 202 and other structures. A liquid storage chamber 203 is formed in the housing 201, the atomizer assembly 100 is disposed in the housing 201, the atomization channel 10 is disposed inside the liquid storage chamber 203, and the nozzle 202 is disposed at one end of the housing 201. Other structures and operations of the atomizer 200 have been recorded in the relevant art for ordinary technicians in the field, and will not be described in detail here.

[0048] In the description of this specification, if the reference terms "one embodiment", "some examples", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0049] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
