Technical Field

[0001] This application relates to the field of aerosol manufacturing, and more particularly to a main unit and an aerosol generating device. Background Technology

[0002] Aerosol generating devices typically consist of two parts: a mod and an atomizer. The mod and atomizer must be electrically connected via their respective conductive electrodes to produce the aerosol for the user. Currently, due to the variety of atomizer types, the connection between the mod and atomizer requires a one-to-one contact connection, necessitating electrical connections between the mod's electrodes and the atomizer's electrodes. This places high demands on the mod's compatibility. However, in existing technologies, components on the mod are generally fixedly mounted, resulting in poor compatibility and limited compatibility with different types of atomizers. Summary of the Invention

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Currently, aerosol generating devices consist of two parts: a main unit and an atomizer. Most atomizers are replaceable, while the main unit is reusable. This requires high assembly stability between the main unit and the atomizer, as well as high electrical connection stability and high assembly versatility. However, the components on existing main units are mostly fixedly mounted, resulting in poor compatibility between the main unit and the atomizer, thus limiting the application range of the main unit. Based on this, according to one aspect of this application, a main unit is provided, comprising:

[0035] The main body 1 is provided with an air intake channel 2 and a mounting slot 3 communicating with the air intake channel 2;

[0036] An electrical mechanism 4 is disposed in the mounting groove 3. The electrical mechanism 4 is electrically connected to the main body 1 and has a first air outlet channel 7 that communicates with the air inlet channel 2. The electrical mechanism 4 is movably disposed relative to the main body 1 so that the electrical mechanism 4 can protrude from or retract from the main body 1.

[0037] refer to Figure 1-7 As shown, in this embodiment, the electrical mechanism 4 can be slidably engaged with the main body 1. Specifically, a slide rail (not shown in the figure) can be provided on the main body 1, allowing the electrical mechanism 4 to slide relative to the mounting surface 100 between the main body 1 and the atomizer via the slide rail. Specifically, in actual use, the electrical mechanism 4 can protrude relative to the mounting surface 100 via the slide rail to accommodate the situation where the atomizer electrode is recessed into the atomizer relative to the mounting surface 100. The electrical mechanism 4 can also be flush with or recessed relative to the mounting surface 100 via the slide rail to accommodate atomizer electrodes with different extension heights relative to the mounting surface 100.

[0038] In addition, the electrical mechanism 4 has a first air outlet channel 7. Specifically, the first air outlet channel 7 can be opened inside the electrical mechanism 4 so that the first air outlet channel 7 is connected to the air inlet channel 2 of the main unit. On the one hand, this increases the comprehensiveness of the functions of the electrical mechanism 4, and on the other hand, the first air outlet channel 7 can solve the problem that when the air inlet positions of different atomizers are different, air cannot be supplied to the atomizer through the air inlet of the main unit's air inlet channel 2 alone.

[0039] refer to Figure 3 A schematic diagram of the overall structure of a host electrical mechanism 4 provided in this application embodiment and Figure 4 As an example, an exploded structural diagram of a host electrical mechanism 4 provided in this application embodiment is shown. A limiting member 9 can also be provided between the host body 1 and the electrical mechanism 4, so that the electrical mechanism 4 can be limited and fixed in the mounting groove 3. The limiting member 9 can be set at different positions in the mounting groove 3, or multiple limiting members 9 can be set along the protruding or retracting direction of the electrical mechanism 4. In actual use, the position of the electrical mechanism 4 relative to the mounting groove 3 can be adjusted by the limiting member 9, thereby adjusting the positional relationship between the electrical mechanism 4 and the host body 1 and the atomizer column body assembly surface 100, so as to adapt to different atomizers. Specifically, it can adapt to different protrusion heights of atomizer electrodes relative to the assembly surface 100.

[0040] As an example, the limiting member 9 can be configured as a ball that can be elastically engaged with the mounting groove 3. The ball can be elastically engaged with one side of the wall of the mounting groove 3, thereby limiting and fixing it in the mounting groove 3, which facilitates the adjustment of the relative position of the electrical mechanism 4 with respect to the main body 1.

[0041] More specifically, a threaded structure can be provided on the mating surface of the electrical mechanism 4 and the mounting groove 3 to allow the electrical mechanism 4 to rotate relative to the mounting groove 3. The thread can also control the height by which the electrical mechanism 4 protrudes or retracts relative to the mounting surface 100 toward the atomizer side. In this embodiment, those skilled in the art can rotatably connect one end of the electrical mechanism 4 to the main body 1, ensuring that the electrical mechanism 4 remains in contact with and electrically connected to the main body 1 when rotating relative to it.

[0042] According to one embodiment of this application, the electrical mechanism 4 includes an electrode connection portion 5 and an electrode docking portion 6. The electrode connection portion 5 is electrically connected to the main body 1 and is provided with the first air outlet channel 7. The electrode docking portion 6 is electrically connected to the electrode connection portion 5. The electrode connection portion 5 is movably disposed relative to the main body 1 so that the electrode connection portion 5 can protrude or retract within the main body 1.

[0043] refer to Figure 2 As shown in the illustration, the electrode docking portion 6 can be sleeved on the electrode connecting portion 5, allowing the electrode docking portion 6 to be movably connected to the electrode connecting portion. Furthermore, the degree to which the electrical mechanism 4 protrudes or retracts relative to the main body 1 can be further adjusted via the electrode docking portion 6. Those skilled in the art can adjust the displacement distance between the electrode docking portion 6 and the electrode connecting portion 5 relative to the main body 1 according to actual usage requirements and the type of atomizer; this will not be described in detail in this application.

[0044] According to one embodiment of this application, the electrode connection portion 5 includes a connection body 501 and a movable body 502. The connection body 501 is electrically connected to the main body 1 and has a first sub-channel 701 communicating with the air intake channel 2. The movable body 502 has a second sub-channel 702 and is movably inserted into the connection body 501, so that the first sub-channel 701 and the second sub-channel 702 cooperate to form the first air outlet channel 7, and the movable body 502 can protrude from or retract from the main body 1.

[0045] As an example, the movable body 502 and the connecting body 501 are movably connected. The movable body 502 and the connecting body 501 can be arranged coaxially, and the movable body 502 is arranged on the side closer to the atomizer body. The movable body 502 and the connecting body 501 are rotatably connected, so that the movable body 502 can protrude or retract towards the atomizer side through the connecting body 501 by rotation.

[0046] refer to Figure 2As shown, in this embodiment, the end of the connecting body 501 and the electrode docking part 6 near the mounting surface 200 can be flush, so that the movable body 502 can be completely retracted into the connecting body 501, and both the movable body 502 and the electrode docking part 6 can be electrically connected to the atomizer electrode 300, further improving the stability of the electrical connection between the host and the atomizer.

[0047] Alternatively, the connecting body 501 and the movable body 502 can be threaded together. In use, the positional relationship between the movable body 502 and the mounting surface 100 can be changed by the thread to adapt to different atomizer electrodes and to make the atomizer electrodes electrically connected to the movable body 502.

[0048] In this embodiment, the movable body 502 is electrically connected to the connecting body 501, which allows the connecting body 501 to be disposed on the side of the mounting surface 100 close to the main body 1, and the movable body 502 to extend from the mounting surface 100 toward the atomizer side. The rotatable connection between the movable body 502 and the connecting body 501 improves the convenience for the user during use.

[0049] It should be further noted that there is at least a partial connection between the movable body 502 and the connecting body 501 to ensure sufficient rotational operating surface during rotation between the movable body 502 and the connecting body 501. Furthermore, those skilled in the art can set the relative movement distance between the movable body 502 and the connecting body 501, or set the height of the movable body 502 protruding from the mounting surface 100 toward the atomizer, according to actual conditions; these details will not be elaborated upon in this application.

[0050] As an example, the movable body 502 can be coaxially inserted into or outside the connecting body 501 so that the second sub-channel 702 and the first sub-channel 701 are interconnected to form the first air outlet channel 7, which is connected to the air inlet channel 2 of the main body 1. By protruding or retracting the main body 1 of the movable body 502, the height of the electrical mechanism 4 protruding or retracting relative to the main body 1 can be adjusted, thereby increasing the compatibility of the main body.

[0051] refer to Figure 2-4 As shown, according to one embodiment of this application, the first sub-channel 701 is provided with a first elastic member 8, and the two ends of the first elastic member 8 respectively abut against the connecting body 501 and the movable body 502, so that the movable body 502 is movably inserted into the connecting body 501.

[0052] As an example, the first elastic element 8 can be configured as a spring or a clip, so that both ends of the first elastic element 8 can abut against and be assembled to the movable body 502 and the connecting body 501. Specifically, an abutment platform 14 can be provided on the side of the connecting body 501 facing the movable body 502, so that both ends of the first elastic element 8 are respectively assembled to the abutment platform 14, and the abutment platform 14 serves as a force-bearing point, so that the movable body 502 can generate elastic displacement relative to the connecting body 501 through the first elastic element 8, thereby controlling the electrical mechanism 4 to protrude or retract relative to the main body 1, thereby adapting to different heights of the atomizer electrode relative to the mounting surface 100, so that the electrical mechanism 4 and the atomizer electrode achieve elastic abutment and electrical conduction, thereby achieving a stable electrical connection between the main body and the atomizer.

[0053] refer to Figure 5 This application provides another overall cross-sectional structural schematic diagram of a host computer as an embodiment of the present application. Figure 6 The enlarged schematic diagram of the structure at point B of a host provided in an embodiment of this application shows that, according to one embodiment of this application, the electrical mechanism 4 includes an electrode and an air guide tube 11, the mounting groove 3 includes a first sub-mounting groove 301 and a second sub-mounting groove 302, the electrode is disposed in the first mounting groove 3 and electrically connected to the host body 1, and the air guide tube 11 is movably disposed in the second sub-mounting groove 302 and is provided with the first air outlet channel 7, so that the air guide tube 11 can protrude or retract within the host body 1.

[0054] As an example, the air duct 11 is slidably fitted into the second sub-mounting slot 302, and the first air outlet channel 7 is disposed within the air duct 11. The air duct 11 is connected to the air inlet channel 2 of the main body 1. Simultaneously, the contraction or protrusion of the air duct 11 relative to the main body 1 enables electrical conduction between the main electrode 10 and the atomizer electrode. This avoids the main body and atomizer being constantly electrically connected when not in use, thus preventing some power loss. Furthermore, the air duct 11 can be movably fitted into the second sub-mounting slot 302, allowing the distance of the air duct 11 protruding towards the atomizer relative to the main body 1 to be changed, or the distance between the mounting surface 100 of the main body and the atomizer to be away from the atomizer, to adapt to atomizers with different air inlet positions or heights, thereby improving the airflow between the main body and the atomizer.

[0055] Furthermore, the air guide tube 11 and the main electrode 10 can have a height difference relative to the mounting surface 100. Specifically, the protrusion height of the air guide tube 11 towards the atomizer side can be greater than the height of the main electrode 10. When the user uses it, a certain pressure can be applied to the air guide tube 11 through the fitting position of the atomizer. The air guide tube 11 retracts into the main body 1 relative to the second sub-mounting groove 302 until the atomizer electrode and the main electrode 10 are electrically connected. At this time, the first air outlet channel 7 in the air guide tube 11 is connected to the air inlet channel 2 of the main body 1, realizing a stable air connection.

[0056] As one embodiment, a certain interval can be set between the first sub-mounting slot 301 and the second sub-mounting slot 302, or the first sub-mounting slot 301 and the second sub-mounting slot 302 can be coaxially sleeved on the main body 1 to adapt to different atomizer types. Those skilled in the art can set it according to the actual use situation, and this application will not describe it in detail.

[0057] According to one embodiment of this application, the second sub-mounting groove 302 is provided with an air guide tube 12, the two ends of which abut against the main body 1 and the air guide tube 11, respectively. The contraction of the air guide tube 12 causes the air guide tube 11 to contract relative to the main body 1, that is, the air guide tube 11 moves relative to the mounting surface 100 toward the main body 1 until the main electrode 10 and the atomizer electrode are electrically connected.

[0058] As an example, the air guide tube 12 may be configured as a spring or elastic clip, so that the air guide tube 12 can elastically contract or release relative to the axial direction of the air guide tube 11.

[0059] According to one embodiment of this application, the main body 1 of the host is further provided with a second air outlet channel 13 communicating with the air inlet channel 2.

[0060] As an example, the second air outlet channel 13 can be disposed on the mounting surface 100 of the atomizer and the main unit. Furthermore, the second air outlet channel 13 can be disposed on the surface of the main unit facing the atomizer. The mounting surface 100 of the main unit body 1 is provided with a second air outlet channel 13 that connects the external gas and the air inlet of the atomizer. Through the second air outlet channel 13, the air communication between the atomizer and the main unit can be further realized, thereby further improving the compatibility of the main unit.

[0061] refer to Figure 5-7As shown, according to one embodiment of this application, the electrical mechanism 4 is provided with an air outlet 15 that communicates with the first air outlet channel 7, and when the electrical mechanism 4 retracts or protrudes from the main body 1, the air outlet 15 is in a state of being connected or not connected with the second air outlet channel 13, respectively.

[0062] Furthermore, the air outlet 15 can be positioned on the side wall of the electrical mechanism 4. When the electrical mechanism 4 retracts relative to the main body 1, until it retracts to the point where the electrical mechanism 4 is electrically connected to the atomizer electrode, the air outlet 15 communicates with the second air outlet channel 13, thereby achieving communication between the first air outlet channel 7 and the second air outlet channel 13, and further achieving communication between the second air outlet channel 13 and the air inlet channel 2.

[0063] When the electrical mechanism 4 protrudes relative to the main body 1, until the electrical mechanism 4 and the atomizer electrode are in a non-electrically conductive state, the air outlet 15 and the first air outlet channel 7 are misaligned, which means that the first air outlet channel 7 and the second air outlet channel 13 are in a non-connected state.

[0064] This allows users to easily control the airflow between the first air outlet channel 7 and the second air outlet channel 13 inside the main unit by changing the protruding and retracting position of the electrical mechanism 4 relative to the main unit body 1, thereby achieving synchronization of electrical and airflow between the main unit and the atomizer and improving the user experience.

[0065] refer to Figure 8-10 As shown, according to another aspect of this application, an aerosol generating apparatus is provided, including the aforementioned host unit.

[0066] According to one embodiment of this application, the aerosol generating device further includes an atomizer 200, the atomizer 200 including an atomizer electrode 300, the electrical mechanism 4 being retractable relative to the atomizer electrode 300 until the atomizer electrode and the electrical mechanism 4 reach the mounting surface 100, thereby achieving a stable electrical connection, the first air outlet channel 7 inside the electrode mechanism being connected to the air inlet channel 2 of the main body 1, and air being supplied to the atomizer through the first air outlet channel 7.

[0067] refer to Figure 9 The schematic diagram of a state structure of an aerosol generating device C provided in this embodiment shows that the atomizer electrode 300 has a through hole adapted to the electrical mechanism 4. The electrical mechanism 4 protrudes relative to the main body and can be inserted into the atomizer electrode 300, thereby adapting to the atomizer with the through hole.

[0068] refer to Figure 10This is a schematic diagram of another state structure of the aerosol generator C provided in this embodiment. In this embodiment, the atomizer electrode 300 does not correspond to the through hole adapted to the electrical mechanism 4. Therefore, when the atomizer electrode 300 is electrically connected to the electrical mechanism 4, the electrical mechanism 4 retracts relative to the main body 1 to adapt to the atomizer electrode 300 and form a stable electrical contact.

[0069] According to one embodiment of this application, the atomizer electrode includes an atomizer air inlet channel. When the electrical mechanism 4 protrudes relative to the main body 1, the electrical mechanism 4 can be inserted into the atomizer air inlet channel to realize the electrical connection and air communication between the main body and the atomizer.
