[0002] At present, there are two ways to heat the aerosol generating substrate: contact heating and non-contact heating. Contact heating is further divided into external heating and central heating. Among them, external heating is to place the heating component on the periphery of the aerosol generating substrate and heat it from the outside of the aerosol generating substrate; central heating is to insert the heating element (such as a heating device with a heating needle, heating rod, heating sheet, etc.) into the aerosol generating substrate and heat it from the inside of the aerosol generating substrate.

[0003] In the central heating method, since the heating element is directly inserted into the aerosol generating matrix for heating, the residue generated is easily retained on the heating element, and the cavity containing the aerosol generating matrix will also have residues. In order to facilitate the cleaning of the residues, the receiving part of the aerosol generating matrix in the atomizing device is usually set to be able to exit the atomizing device. However, in the related art, the atomizing device mostly uses a magnetic suction method or an electric lifting method to assist the aerosol generating matrix to exit, which is a complex structure and high cost.

In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0036] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0037] See also Figure 1The embodiment of the present application provides an atomizing device 100 and an atomizing equipment. The atomizing equipment includes the atomizing device 100, a power supply assembly, and a shell assembly 200. The power supply assembly and the atomizing device 100 are both arranged in the shell assembly 200, and part of the atomizing device 100 extends out of the shell assembly 200. The power supply assembly is electrically connected to the atomizing device 100 and is used to supply power to the atomizing device 100. The atomizing device 100 is used to atomize an aerosol generating matrix 300 to generate an aerosol.

[0038] See also Figure 1 , Figure 2 and Figure 4 The atomizing device 100 includes a shell 10, a receiving piece 20 and a heating assembly 30; the receiving piece 20 has a receiving cavity 211, and the receiving cavity 211 is used to receive the aerosol generating matrix 300; the shell 10 has a mounting cavity 11, a first opening 12 and a second opening 13, the first opening 12 and the second opening 13 are arranged opposite to each other along the axial direction of the shell 10, and are both connected to the mounting cavity 11; the receiving piece 20 is inserted into the shell 10 through the first opening 12, and the heating assembly 30 extends into the shell 10 through the second opening 13 and extends into the receiving cavity 211.

[0039] The shape of the installation cavity 11 matches the outer contour of the receiving member 20, so that the receiving member 20 can be inserted into the installation cavity 11; and the shape of the receiving cavity 211 matches the outer contour of the aerosol generating matrix 300, so that the aerosol generating matrix 300 can be inserted into the receiving cavity 211. In a specific implementation, the shapes of the installation cavity 11 and the receiving cavity 211 can be set to be cylindrical, which is convenient for processing and manufacturing, and is conducive to the insertion and removal of the receiving member 20 and the aerosol generating matrix 300.

[0040] When the aerosol generating matrix 300 and the heating component 30 are both located in the receiving cavity 211, the heating component 30 can extend into the interior of the aerosol generating matrix 300. After power is turned on, the heating component 30 directly heats the aerosol generating matrix 300 in a central heating manner, thereby atomizing the aerosol generating matrix 300 to generate an aerosol.

[0041] In specific implementation, one operation mode is: first insert the aerosol generating matrix 300 into the receiving cavity 211, then insert the receiving member 20 with the aerosol generating matrix 300 inserted into the installation cavity 11, and during the process of inserting the receiving member 20 into the installation cavity 11, the heating component 30 extends into the receiving cavity 211 and is simultaneously inserted into the interior of the aerosol generating matrix 300. Another operation mode is: first insert the receiving member 20 without the aerosol generating matrix 300 inserted into the installation cavity 11, and during the process of inserting the receiving member 20 into the installation cavity 11, the heating component 30 extends into the receiving cavity 211, and then insert the aerosol generating matrix 300 into the receiving cavity 211, and during the process of inserting the aerosol generating matrix 300, the heating component 30 located in the receiving cavity 211 is simultaneously inserted into the interior of the aerosol generating matrix 300.

[0042] See also Figure 1 and Figure 2 The heating assembly 30 includes a heating needle 31 and a mounting seat 32. The mounting seat 32 is inserted into the second opening 13. The heating needle 31 is fixed to the mounting seat 32 and extends into the mounting cavity 11. When the receiving member 20 is inserted into the mounting cavity 11, the heating needle 31 extends into the receiving cavity 211. In a specific implementation, the heating needle 31 is inserted into the interior of the aerosol generating matrix 300. When the heating needle 31 is powered on, it provides heat to the aerosol generating matrix 300 to generate aerosol.

[0043] The heating needle 31 may generate heat by resistance heating or magnetic induction heating. Here, the heating method of the heating needle 31 is not limited.

[0044] It should be noted that the aerosol generating matrix 300 may be a drug, tobacco, flavor, etc. in the form of solid, liquid, or a solid-liquid mixed state; for example, the components of a typical aerosol generating matrix 300 include propylene glycol, glycerol, nicotine, and flavor substances, etc. It is understandable that the aerosol generating matrix 300 does not constitute a limitation on the atomizing device of this embodiment, and the aerosol generating matrix 300 may depend on the application scenario of the atomizing device, for example, an electronic cigarette may be a specific application embodiment of the atomizing device.

[0045] See also Figures 1 to 3 The atomizing device 100 further includes a first protrusion 40 and a second protrusion 50 . The first protrusion 40 is disposed on the outer side of the receiving member 20 , and the second protrusion 50 is disposed on the inner side of the housing 10 . The receiving member 20 is detachably connected to the housing 10 through interference fit of the first protrusion 40 and the second protrusion 50 .

[0046] By providing a first protrusion 40 on the outside of the receiving member 20 and providing a second protrusion 50 on the inside of the housing 10 that is interference-fitted with the first protrusion 40, when the receiving member 20 is inserted into the housing 10, the first protrusion 40 and the second protrusion 50 are interference-fitted, so that the receiving member 20 is limited in the housing 10. When the receiving member 20 needs to be taken out, the operator applies a certain force to take out or pull out the receiving member 20 from the housing 10, thus achieving a detachable connection between the receiving member 20 and the housing 10. The first protrusion 40 and the second protrusion 50 are simple in structure and easy to manufacture, and can effectively reduce costs compared to the complex structures (such as magnetic attraction or electric lifting) used in the related art.

[0047] The aerosol generating matrix 300 is inserted into the receiving member 20 and can move with the movement of the receiving member 20. By detachably connecting the receiving member 20 with the outer shell 10, the receiving member 20 can be inserted into the outer shell 10 or taken out from the outer shell 10, thereby realizing the insertion or withdrawal of the aerosol generating matrix 300 into or out of the outer shell 10.

[0048] In another embodiment, the first protrusion 40 or the second protrusion 50 may be configured as a groove, and the detachable connection between the receiving member 20 and the housing 10 is achieved through the snap-fitting between the protrusion and the groove.

[0049] In one embodiment, the interference amount W of the first protrusion 40 and the second protrusion 50 is 0.05mm to 0.2mm. Within the range of the interference amount W, on the one hand, the receiving member 20 can be firmly confined in the installation cavity 11, and on the other hand, the user can remove the receiving member 20 from the housing 10 by applying a certain external force, and the external force does not need to be too large. Preferably, the interference amount W is 0.08mm to 0.15mm. In a specific implementation, the interference amount W can be 0.05mm or 0.07mm or 0.1mm or 0.13mm or 0.15mm or 0.18mm or 0.2mm, etc.

[0050] In one embodiment, the outer surfaces of the first protrusion 40 and the second protrusion 50 are both arc-shaped or curved. During the insertion or removal of the receiving member 20, the first protrusion 40 and the second protrusion 50 abut against each other and move relative to each other. By setting the outer surfaces of the protrusions to be arc-shaped or curved, it is avoided that the two protrusions generate excessive resistance between each other during movement, thereby facilitating the insertion or removal of the receiving member 20.

[0051] It is understood that in other embodiments, the outer surfaces of the first protrusion 40 and the second protrusion 50 may also be set to other shapes. For example, the protrusion includes an upper surface inclined downward and a lower surface inclined upward, and the upper surface and the lower surface are smoothly transitioned.

[0052] It should be noted that the limitation of directional words such as upper and lower in this application is for the convenience of understanding. The description made when the atomizer is in use is only used to reflect the relative position relationship between the structures. When the atomizer is in other postures, the directional words in this application should be understood after switching to the use state.

[0053] In one embodiment, the first protrusion 40 includes an annular first protrusion 41 or a plurality of first protrusions 41 arranged at intervals along the circumference of the receiving member 20; the second protrusion 50 includes an annular second protrusion 51 or a plurality of second protrusions 51 arranged at intervals along the circumference of the housing 10. Figure 5 and Figure 6 The first protrusion 40 includes two first protrusions 41, and the two first protrusions 41 are arranged at equal intervals along the circumference of the receiving member 20. The second protrusion 50 includes two second protrusions 51, and the two second protrusions 51 are arranged at equal intervals along the circumference of the outer shell 10. The first protrusions 41 and the second protrusions 51 correspond to each other one by one.

[0054] It should be noted that the present application does not limit the number of the first protrusions 41 and the second protrusions 51 , and the number of the first protrusions 41 and the second protrusions 51 may also be three, four, five, or the like.

[0056] In another embodiment, the first protrusion 40 may be disposed on a side of the second sleeve 23 away from the first sleeve 22 . When the receiving member 20 is inserted into the installation cavity 11 , at least a portion of the second sleeve 23 is inserted into the installation cavity 11 .

[0057] See also Figure 2, a buckle 24 is provided on the outside of the carrying cup 21, that is, a buckle 24 is provided on the side of the carrying cup 21 facing away from the receiving cavity 211, and a slot 25 matching the buckle 24 is provided on the inside of the first sleeve 22, that is, a slot 25 is provided on the side of the first sleeve 22 facing the carrying cup 21. When the first sleeve 22 is sleeved on the periphery of the carrying cup 21, the carrying cup 21 is fixedly connected by the buckle 24 and the slot 25. It can be understood that in other embodiments, the slot 25 is provided on the outside of the carrying cup 21, and the buckle 24 is provided on the inside of the first sleeve 22.

[0058] In one embodiment, the supporting cup 21 is spaced apart from the first sleeve 22 to form a spacing space, the first sleeve 22 and the second sleeve 23 are respectively provided with a first vent and a second vent, the first vent is connected to the second vent and the spacing space, the second vent is connected to the outside of the atomizing device, and the supporting cup 21 is also provided with a third vent that connects the receiving cavity 211 and the spacing space, so that the second vent, the first vent, the spacing space and the third vent form an air inlet channel. The gas outside the atomizing device can flow into the receiving cavity 211 through the air inlet channel, that is, it can flow into the aerosol generating matrix 300 located in the receiving cavity 211, and then the aerosol can be discharged with the airflow.

[0059] See also Figure 2 , Figures 5 to 7 The first sleeve 22 includes a sleeve portion 221, a first extension portion 222 and a second extension portion 223; the second extension portion 223 is connected between the sleeve portion 221 and the first extension portion 222, the sleeve portion 221 is sleeved inside the second sleeve 23, the first extension portion 222 and the second extension portion 223 are both extended outside the second sleeve 23, when the receiving member 20 is inserted into the shell 10, the first extension portion 222 and the second extension portion 223 are both accommodated in the installation cavity 11, and the first protrusion 40 is provided on the outer surface of the first extension portion 222. In specific implementation, when the receiving member 20 is inserted into the shell 10, one end of the second sleeve 23 abuts against one end of the shell 10 provided with the first opening 12, that is, the second sleeve 23 is supported on the shell 10. In addition, a step 14 is further provided inside the shell 10, when the receiving member 20 is inserted into the shell 10, one end of the first extension portion 222 away from the second extension portion 223 is supported on the step 14. In this way, the receiving member 20 can be firmly inserted into the housing 10 .

[0060] In one embodiment, the first protrusion 40 is disposed at one end of the first extension 222 away from the second extension 223. The elasticity of the end region of the sleeve is generally greater than the elasticity of the middle region of the sleeve. The first protrusion 40 is disposed at one end of the first extension 222 away from the second extension 223, and the first protrusion 40 is disposed close to the end of the first sleeve 22, thereby increasing the elasticity of the first protrusion 40, which is beneficial to the insertion and removal of the receiving member 20.

[0061] Furthermore, in one embodiment, the height H of the first protrusion 40 is 1 smaller than the height H of the second protrusion 50 2 In this way, during the insertion or removal of the receiving member 20, the resistance between the inner wall of the housing 10 and the first protrusion 40 is smaller than the resistance between the second protrusion 50 and the outer wall of the first sleeve 22. In combination with the end of the first protrusion 40 close to the first sleeve 22, the stroke of the first protrusion 40 is greater than the stroke of the second protrusion 50, which facilitates the insertion or removal of the receiving member 20. Of course, in other embodiments, the height H of the first protrusion 40 is 1 is set to be equal to or greater than the height H of the second protrusion 50 2 The height H of the first protrusion 40 is 1 It refers to the maximum dimension of the first protrusion 40 in the radial direction of the first sleeve 22; the height H of the second protrusion 50 2 It refers to the maximum dimension of the second protrusion 50 in the radial direction of the housing 10 .

[0062] In one embodiment, the first extension portion 222 is provided with a plurality of through holes 224, which are provided beside or around the first protruding portion 40 to adjust the elasticity of the first protruding portion 40. By providing a plurality of through holes 224, the elasticity of the first protruding portion 40 can be increased, thereby facilitating the insertion or removal of the receiving member 20. Figure 6 In this embodiment, a through hole 224 with a notch is provided on both sides of the first protrusion 40, which can increase the elasticity of the first protrusion 40 and facilitate processing. Of course, in another embodiment, Figure 8 As shown, it is also possible to provide a plurality of through holes 224 in the circumferential direction of the first protruding portion 40 .

[0063] It should be noted that the present application does not limit the shape and number of the through hole 224. For example, the through hole 224 can be set to a circle, an ellipse, a triangle, a regular polygon or any irregular shape, etc. For another example, the through hole 224 can be set to two, three, or five, etc. In addition, the through hole 224 can also be replaced by other structures, such as a blind hole, a groove, etc.

[0064] In one embodiment, when the receiving piece 20 is inserted into the housing 10, there is a gap between the first extension 222 and the housing 10, and the gap ranges from 0.05 mm to 1.5 mm. This arrangement can reduce the resistance of the first extension 222 and the first protrusion 40 during the insertion or removal of the receiving piece 20, which is conducive to the insertion or removal of the receiving piece 20. In a specific implementation, when the receiving piece 20 is inserted into the housing 10, there is a gap between the first extension 222 and the housing 10, and the second extension 223 contacts the inner wall of the housing 10. In this way, on the one hand, the receiving piece 20 is as easy to insert or remove as possible, and on the other hand, the receiving piece 20 is prevented from shaking in the housing 10, thereby improving the stability of the receiving piece 20 when it is inserted into the housing 10.

[0065] The first sleeve 22 and the housing 10 are both made of a material with certain strength and elasticity, such as plastic.

[0066] See also Figure 1 and Figure 2 The shell assembly 200 can be understood as a collection of related structural parts that constitute the basic structural framework and outer contour of the atomization device. For example, the shell assembly 200 can adopt a rectangular hollow structure constructed by combining multiple structural parts; the atomization device 100 and the power supply assembly are both connected to the shell assembly 200 to form a complete atomization device; the user can hold, move, operate and use the atomization device with the help of the shell assembly 200.

When the receiving piece 20 is inserted into the housing 10, the first protrusion 40 and the second protrusion 50 are interference fit, so that the receiving piece 20 is limited in the housing 10. When the receiving piece 20 needs to be taken out, the operator applies a certain force to take out or pull out the receiving piece 20 from the housing 10. This arrangement realizes the detachable connection between the receiving piece 20 and the housing 10. The first protrusion 40 and the second protrusion 50 are simple in structure and easy to manufacture. Compared with the complex structure (such as magnetic attraction or electric lifting) used in the related art, the cost can be effectively reduced.
