DETAILED DESCRIPTION

[0035] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0037] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0038] Existing heat-not-burn (HNB) atomizers, such as heat-not-burn (HNB) smoking devices, feature a nozzle attached to the heated element through which users inhale. For example, the cigarette stick / cartridge used in HNB smoking devices mimics a traditional cigarette, featuring a nozzle and an aerosol matrix. A cooling chamber and other components are also required if necessary. The only useful component of the cigarette stick is the aerosol matrix (e.g., tobacco); any other components increase the cost of the cigarette. Furthermore, the reliance on the nozzle attached to the heated element restricts the structural design of the atomizer device, limiting its diversified development.

[0039] The embodiments of the present application provide a nozzle assembly and an atomization device, wherein the heated component may only include an aerosol matrix, without other components such as a nozzle, and the nozzle assembly can realize convenient loading and unloading, providing a novel smokeable heating without burning solution, which is conducive to the development of atomization equipment.

[0040] like Figures 2 to 5 As shown, an embodiment of the present application provides a nozzle assembly 100 , which may include: a nozzle 11 , an elastic member 12 and a slider 13 .

[0041] The interior of the nozzle 11 has a continuous airflow channel 111. The elastic member 12 and the slider 13 are both disposed within the airflow channel 111. The elastic member 12 is disposed between the slider 13 and the nozzle 11. The slider 13 has a first channel 131 disposed therein, which communicates with the airflow channel 111. The elastic member 12 is provided to ensure that the first channel 131 and the airflow channel 111 are not blocked, and the specific implementation is not limited. The airflow channel 111 and the first channel 131 can be regular or irregular channels, as long as airflow can pass smoothly.

[0042] The outside of the slider 13 has a first snap-fit structure 132, and the inner wall of the airflow channel 111 has a second snap-fit structure 112 matching the first snap-fit structure 132. Figure 3 As shown, the first snap-fit structure 132 can be a groove, and the second snap-fit structure 112 can be a protrusion. For another example, the first snap-fit structure 132 can be a protrusion, and the second snap-fit structure 112 can be a groove.

[0043] The end of the air flow channel 111 close to the slider 13 serves as the air inlet end (eg Figure 3 The lower end shown in FIG), the other end away from the slider 13 is used as the air outlet end (as shown in FIG). Figure 3 The air inlet end has a first mounting groove 113, the first mounting groove 113 matches the heated member 10, and the first mounting groove 113 is configured to mount the heated member 10. For example, Figure 4 As shown, half of the heated element 10 can be installed in the first installation groove 113, and the other half can be installed in the heating chamber 231 of the heating assembly 200. Generally, the cigarette cartridge is set to be cylindrical, and in this case, the first installation groove 113 can be set to a corresponding cylindrical groove.

[0044] like Figure 4 As shown, during the process of installing the heated component 10 into the first installation groove 113, the heated component 10 pushes the slider 13 to move from the second preset position to the first preset position and compresses the elastic component 12; the second snap-fit structure 112 is configured to snap-fit and connect with the first snap-fit structure 132 when the slider 13 moves to the first preset position, thereby limiting further movement of the slider 13.

[0045] For example, Figure 4 As shown, at this time the slider 13 moves to the first preset position, as shown in FIG. Figure 5 As shown, at this time the slider 13 moves to the second preset position.

[0046] The nozzle 11 is elastic and has a pressure receiving portion 114 on the outside. Figure 5As shown, the pressure-bearing portion 114 is configured to release the snap connection between the second snap structure 112 and the first snap structure 132 under external force, and the elastic member 12 is configured to reset the slider 13 from the first preset position to the second preset position and push the heated member 10 out of the first mounting groove 113.

[0047] For example, when a user needs to use an atomizing device for inhalation, Figure 4 As shown, the heated component 10 is installed in the first installation groove 113. At this time, the slider 13 is fixed in the nozzle 11 through the first snap structure 132 and the second snap structure 112. Then, the nozzle assembly 100 with the heated component 10 can be installed in the heating assembly 200. After the heating and atomization are completed, the nozzle assembly 100 is removed from the heating assembly 200. Figure 5 As shown, the pressed portion 114 is pinched by fingers. Since the suction nozzle 11 is elastic, the suction nozzle 11 is deformed by pressure, the second snap-fit structure 112 is released from the first snap-fit structure 132, and the elastic member 12 pushes the slider 13 outward, and the part to be heated 10 is pushed out from the first mounting groove 113, thereby achieving automatic pop-up of the part to be heated 10.

[0048] like Figures 2 to 5 As shown, in one embodiment, the elastic member 12 may be a spring. The airflow channel 111 has a first mounting portion 115 inside that matches the end of the spring, and the slider 13 has a second mounting portion 133 that matches the end of the spring. The two ends of the spring are respectively mounted on the first mounting portion 115 and the second mounting portion 133. The spring can be fixed by the first mounting portion 115 and the second mounting portion 133, and the spring does not block the first channel 131 or the airflow channel 111. In addition, the spring is made of metal with good thermal conductivity and can also cool the aerosol, preventing users from being burned by high-temperature aerosol.

[0049] like Figure 4 and Figure 5 As shown, in one embodiment, the axial direction of the airflow channel 111, the axial direction of the spring, and the axial direction of the first channel 131 are parallel. The slider 13 and the spring are arranged coaxially, which ensures that the slider 13 moves smoothly in the airflow channel 111, so that the heated element 10 can be easily installed and ejected, while also ensuring that the aerosol / airflow flows smoothly in the airflow channel 111.

[0050] To sum up, the suction nozzle assembly 100 provided in the embodiment of the present application can realize the convenient installation and disassembly of the heating component 10, and the suction nozzle 11 is provided in the suction nozzle assembly 100, so there is no need to set a suction nozzle in the cigarette / cigarette cartridge, which can reduce costs and get rid of the limitation of setting a suction nozzle in the heating component 10, which is conducive to the development of atomization equipment.

[0051] like Figures 6 to 10As shown, an embodiment of the present application further provides an atomizing device, which may include: a heating component 200 and the nozzle component 100 described in the above embodiment.

[0052] The heating assembly 200 has a heating chamber 231 that matches the heated member 10. The heated member 10 is partially mounted in the first mounting groove 113 and partially mounted in the heating chamber 231. The first mounting groove 113 exerts a greater force on the heated member 10 than the heating chamber 231, so that when the suction nozzle assembly 100 is removed from the heating assembly 200, the heated member 10 remains on the suction nozzle 11. For example, the first mounting groove 113 and the heated member 10 have an interference fit, while the heated member 10 and the heating chamber 231 have a loose fit; that is, the first mounting groove 113 and the heated member 10 have a tighter fit.

[0053] When using the atomization device, the user installs the heated part 10 into the first installation groove 113 of the suction nozzle assembly 100, and then installs it into the heating chamber 231, starts heating, and after the heating and atomization are completed, the user removes the suction nozzle assembly 100 from the heating assembly 200, squeezes the pressed part 114, and ejects the used heated part 10.

[0054] like Figures 7 to 9 As shown, in one embodiment, the heating assembly 200 may include a mounting frame 23, a heating element 21, and a heat exchange core 22. The heating element 21 is configured to heat the heat exchange core 22. For example, the heating element 21 may be a heating tube, a heating plate, or a heating mesh. In this embodiment of the present application, the heating element 21 heats the heat exchange core 22, thereby indirectly heating the heated element 10.

[0055] The heat exchange core 22 has a through hole or pore; the heating element 21 and the heat exchange core 22 are mounted on one side of the mounting frame 23, and the heating element 10 is mounted on the other side of the mounting frame 23; Figure 7 As shown, the heating element 21 and the heat exchange core 22 are arranged at the lower part of the mounting frame 23, and the upper part of the mounting frame 23 serves as the heating chamber 231.

[0056] In the embodiment of the present application, the heating element 21 is not in contact with the heated element 10, but is in contact with the heat exchange core 22. The heat exchange core 22 may or may not be in contact with the heated element 10. The heat exchange core 22 at least heats the air surrounding it. When the user inhales, a negative pressure is formed at the air outlet, generating airflow. The heat exchange core 22 is upstream of the airflow and heats the airflow. The airflow flows through the heat exchange core 22 and is heated before flowing toward the heated element 10, heating the heated element 10 and generating aerosol. The aerosol follows the airflow and flows from the air inlet end and out from the air outlet end, ultimately being inhaled by the user.

[0057] Such as 6 and Figure 7As shown, in one embodiment, the heat exchange core 22 does not contact the part to be heated 10, and a partition 232 is provided on the inner wall of the mounting frame 23, separating the part to be heated 10 and the heat exchange core 22 by the partition 232. To prevent uneven heating of the part to be heated 10, in the embodiment of the present application, the heat exchange core 22 does not contact the part to be heated 10, and the part to be heated 10 is configured to be heated by hot air flow. The part to be heated 10 itself is provided with through holes or pores, so that the hot air flow can fully flow through the part to be heated 10. Even if the part to be heated 10 is partially disposed in the nozzle assembly 100, it will not affect the sufficient and uniform heating of the part to be heated 10.

[0058] With indirect heating using hot air flow, when the user stops puffing, the heating element 21 stops heating the heated element 10. The preheated energy from the heating element 21 is not directly transferred to the heated element 10, allowing the heated element 10 to cool down immediately. This allows the heated element 10 to be replaced at a lower temperature, thus preventing burns. While the nozzle assembly 100 can eject the heated element 10 via the pressure-bearing portion 114, the indirect heating method relies on the hot air flow to heat the heated element 10, preventing burns even if the heated element 10 is accidentally touched.

[0059] In some embodiments, in order to prevent the high temperature of the heating element 21 from affecting the mounting frame 23, an insulating and high-temperature resistant isolation member 27 may be provided between the heating element 21 and the mounting frame 23, such as a ceramic ring, which is used to fix the heating element 21 in the mounting frame 23 and also serves as insulation and heat insulation.

[0060] In one embodiment, the heating assembly 200 may further include a heating cup body 24 and a base 25, and the mounting frame 23 is disposed in the heating cup body 24 and fixed by at least one of the base 25 and the heating cup body 24. Figure 7 As shown, the mounting frame 23 can be fixed to the heated cup body 24, for example, by being fixed in a manner of being embedded in a jacket, such as Figure 7 As shown, the heating cup body 24 has an opening, and the mounting bracket 23 can be fixed in the heating cup body 24 through the opening from above.

[0061] like Figure 7 As shown, the heating cup body 24 and the base 25 can be detachably fixedly connected, for example, by being fixed in an embedded outer shell, or a seal can be provided between the two to ensure airtightness and prevent the aerosol from leaking to the electrical components (such as batteries and PCB boards, etc.) under the base 25.

[0062] like Figures 6 to 10As shown, in one embodiment, the outside of the suction nozzle 11 has a third mounting portion 116 on one side close to the slider 13, and the heating component 200 has a fourth mounting portion 26 matching the third mounting portion 116. The suction nozzle 11 is fixed to the heating component 200 through the third mounting portion 116 and the fourth mounting portion 26.

[0063] The fourth mounting portion 26 may be an independent component or may be provided at a location in the heating cup body 24. For example, in the embodiment of the present application, the fourth mounting portion 26 is an independent component, such as Figures 6 to 9 The fourth mounting portion 26 shown has an annular structure, and the third mounting portion 116 is a cylindrical shaft structure. The third mounting portion 116 can be embedded in the fourth mounting portion 26 .

[0064] Among them, such as Figure 10 As shown, the atomizing device may further include a shell 40, which may be used to fix the fourth mounting portion 26. The fourth mounting portion 26 is mounted to the opening of the heating cup body 24. The shell 40 may restrict the movement of the fourth mounting portion 26 to prevent the fourth mounting portion 26 from being pulled out when the nozzle assembly 100 is pulled out of the heating assembly 200.

[0065] like Figure 10 As shown, Figure 10 (B) in Figure 10 Cross-sectional view of (A); In one embodiment, the atomizing device may further include a battery assembly 30, and the battery assembly 30 is configured to supply power to the heating assembly 200. The battery assembly 30 is disposed inside the housing 40, and the battery assembly 30 is configured to supply power to the heating assembly 200. For example, the battery assembly 30 may include a rechargeable lithium battery. The built-in rechargeable battery can reduce the trouble of users replacing batteries. At the same time, the rechargeable lithium battery is generally equipped with a charge and discharge management chip, etc., which is safer to use. The atomizing device may further include a charging port (not shown in the figure), which is electrically connected to the battery assembly 30 through a circuit board, and the charging port can charge the battery assembly 30 through the charging circuit on the circuit board. For example, the charging port may be a commonly used USB port such as type-C, which is convenient for users to charge using a conventional power adapter or power bank.

[0066] like Figure 10 As shown, the atomization device may also include structures such as a circuit board, a switch module, and an indicator light (all with reference numerals shown), so that the user can control the electric heating atomization, understand the status of the atomization device, etc. The above-mentioned devices are not the focus of this application and will not be described in detail. This application does not limit the further use of these devices or structures in the atomization device provided in the above embodiments.

[0067] In each of the above embodiments, the atomization device can be a heat-not-burn smoking device, and the heated element 10 can be a cigarette cartridge / cigarette without a mouthpiece, and can contain only an aerosol matrix. This eliminates the reliance on a mouthpiece on the heated element 10 and provides a novel atomization method. However, this does not limit the application of the mouthpiece assembly 100 and atomization device provided in this application to heat-not-burn smoking devices only.

[0068] In summary, the embodiment of the present application provides a nozzle assembly 100 capable of mounting the heated member 10, eliminating the need for a nozzle on the heated member 10. The nozzle assembly 100, through the elastic member 12, slider 13, and elastic nozzle 11, facilitates easy assembly and disassembly of the heated member 10, thereby eliminating the need for a nozzle on the heated member 10 and reducing costs. Based on the nozzle assembly 100, the atomization device can heat the heated member 10 without a nozzle, realizing a new suction-enabled atomization solution that is beneficial to the development of atomization devices.
