Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generation, in particular to an aerosol generating device. Background Art

[0002] Smoking articles such as cigarettes and cigars burn tobacco to produce smoke during use. Attempts have been made to provide alternatives to these tobacco-burning articles by creating products that release compounds without burning them. Examples of such products are so-called heat-not-burn products, which release compounds by heating the tobacco rather than burning it.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0058] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0059] In order to automatically close or open the cover and improve the user experience, this embodiment provides an aerosol generating device, which is combined with Figures 1 to 8 The specific contents of this embodiment are described in detail. It should be noted that the first direction and the width direction mentioned in this embodiment are Figure 2 The X direction in this embodiment is the length direction Figure 2 The Z direction in .

[0060] like Figures 1 to 7As shown, the aerosol generating device in this embodiment is used to heat an aerosol generating product, such as a cigarette 100, to generate an aerosol. The aerosol generating device includes a housing, a cover 3, and an electromagnet assembly. The housing has a heating chamber and an opening 71 connected to the heating chamber, and at least part of the aerosol generating product is removably received in the heating chamber through the opening 71. The cover 3 has a travel relative to the housing, and the travel has a first position for opening the opening 71 and a second position for closing the opening 71. The electromagnet assembly includes a drive mechanism and a movable rod 4, one end of the movable rod 4 is connected to the drive mechanism, and the other end of the movable rod 4 is connected to the cover 3; the drive mechanism is configured to drive the movable rod 4 to move linearly to drive the cover 3 to move between the first position and the second position.

[0061] The aerosol-generating device provided by this utility model is provided with a heating chamber for heating an aerosol-generating product to generate an aerosol. An opening 71 is provided in the housing to facilitate placement of the aerosol-generating product into the heating chamber. The cover 3, movable rod 4, and drive mechanism are sequentially connected. The movable rod 4 is activated by the drive mechanism to move the cover 3 between a first position and a second position, automatically opening or closing the opening 71 of the housing. This eliminates the need for manual manipulation of the cover 3, simplifying the operation process. Users can control the automatic closing or opening of the cover 3 based on their needs, enhancing the user experience.

[0062] Optionally, in this embodiment, the cover 3 is disposed within the housing. The housing comprises an outer shell 1 and an upper cover 7, which together form a protective structure for the aerosol-generating device. An opening 71 is provided on the upper cover 7. The cover 3 and the heater 2 having a heating chamber are located within the outer shell 1. When the cover 3 is in the first position, the aerosol-generating article can enter the heating chamber through the opening 71 on the upper cover 7.

[0063] Optionally, a connector 10 is sleeved onto the heater 2 and is provided with a cigarette insertion port 102. The heater 2 is in communication with the cigarette insertion port 102. With the connector 10 provided on the heater 2, a cigarette 100 is inserted into the heater 2 through the cigarette insertion port 102 of the connector 10, heating the cigarette 100 and generating aerosol. The connector 10 provides thermal insulation, preventing heat from the heater 2 from being transferred to the upper cover 7.

[0064] Furthermore, a first limiting portion 73 and a second limiting portion 72 are provided within the housing. The first limiting portion 73 is used to limit the cover 3 when the cover 3 moves to the first position, and the second limiting portion 72 is used to limit the cover 3 when the cover 3 moves to the second position. The addition of the first limiting portion 73 and the second limiting portion 72 facilitates limiting the travel of the cover 3.

[0065] Further, if Figures 2 to 8As shown, the cover 3 comprises a vertically connected shielding plate 31 and a connecting plate 32. The connecting plate 32 is connected to the movable rod 4. The shielding plate 31 is used to open or close the cigarette insertion port 102. In this embodiment, the cover 3 is preferably made of PC material with good overall performance. The structure, viewed from the side, presents an inverted "L" shape. The shielding plate 31 and connecting plate 32 are connected to form an L shape.

[0066] For example, a first stopper 73 is provided on the bottom surface of the upper cover 7. An opening stopper 322 is provided on the end of the connecting plate 32 away from the shielding plate 31. The opening stopper 322 is stopped by the first stopper 73. A second stopper 72 is provided on the bottom surface of the upper cover 7. A closing stopper 311 is provided on the end of the shielding plate 31 away from the connecting plate 32. The closing stopper 311 is stopped by the second stopper 72. Furthermore, guide stopper ribs 74 are provided between the second stopper 72 and the first stopper 73. Guide stopper surfaces 312 are provided on both sides of the shielding plate 31. The guide stopper surfaces 312 move in a first direction relative to the guide stopper ribs 74. The upper cover 7 is preferably made of PC with excellent comprehensive performance. The main functional structure presents a "D" shape with mirrored left and right sides, with guide stopper ribs 74 at the top and bottom. This structural design is compact and strong, while also reducing warping deformation of the top surface of the upper cover 7.

[0067] Furthermore, the connecting plate 32 is provided with a mounting slot 321, and two annular flanges 41 are provided at intervals on one end of the movable rod 4 away from the electromagnet body 5. The movable rod 4 is inserted into the mounting slot 321, and the connecting plate 32 is clamped between the two annular flanges 41. The mounting slot 321 is in the shape of an "Ω". The notch 3211 at the bottom of the mounting slot 321 is larger than the diameter of the shaft of the movable rod 4. The two sides of the notch 3211 are mounting guide surfaces 3212. The width of the notch 3211 gradually decreases from bottom to top to the neck 3213. The width of the neck 3213 is reduced to a minimum, and the width of the neck 3213 is 0.1-0.5mm less than the diameter of the shaft of the movable rod 4, which can prevent the movable rod 4 from falling out of the mounting slot 321 during the installation process. The top of the mounting slot 321 is a circular hole 3214, the inner diameter of which is 0.1-0.5 mm larger than the diameter of the shaft of the movable rod 4, which can absorb the shape and size tolerances of some parts and the assembly tolerances, and prevent the cover 3 from getting stuck during movement. The cover 3 has a compact structure, light weight, and fast response, and the closing and opening actions can be completed within one second.

[0068] Furthermore, the driving mechanism in this embodiment is configured to drive the movable rod 4 to move linearly along the width direction of the housing. By making the movable rod 4 move linearly along the width direction of the housing, it is convenient to make the movable rod 4 move quickly along a straight line.

[0069] Furthermore, the cover 3 can be moved between a first position and a second position along the width direction of the housing. The movable rod 4 is driven by the driving mechanism to perform linear motion along the width direction of the housing, thereby achieving rapid switching of the cover 3 between the first position and the second position.

[0070] For example, in some application scenarios, the driving mechanism in this embodiment adopts a push-pull electromagnet. The aerosol generating device also includes a battery core 13 for providing electricity, and the driving mechanism includes a reset member and an electromagnet body 5 electrically connected to the battery core 13. When the electromagnet body 5 is in a power-on state, the electromagnet body 5 generates a magnetic force for attracting the movable rod 4 to drive the cover 3 to move to the first position (or the second position) and maintain the position of the cover 3. When the electromagnet body 5 is in a power-off state, the reset member can enable the movable rod 4 to drive the cover 3 to move to the second position (or the first position) and maintain the position of the cover 3. Figure 3 and Figure 4 As shown, the reset member includes an elastic member 6 sleeved on the movable rod 4. The end of the movable rod 4 away from the cover 3 is inserted into the electromagnet body 5, and the elastic member 6 is sleeved on the movable rod 4. When the electromagnet body 5 is energized, the electromagnet body 5 generates a magnetic force, which retracts the movable rod 4 into the electromagnet body 5, causing the movable rod 4 to move the cover 3 and open the cigarette insertion port 102, and the elastic member 6 is compressed; when the electromagnet body 5 is de-energized, the electromagnet body 5 does not generate a magnetic force, and the movable rod 4 is reset under the action of the elastic member 6 and closes the cigarette insertion port 102. At this time, the elastic member is still in a compressed state, continuously pressing against the cover 3, which can prevent the cover 3 from making abnormal noises when the device is shaken.

[0071] For example, in other application scenarios, the driving mechanism in this embodiment adopts a bidirectional self-holding electromagnet. The aerosol generating device also includes a battery core 13 for providing electricity, and the driving mechanism includes a permanent magnet and an electromagnet body 5 electrically connected to the battery core 13; when the electromagnet body 5 is in a forward energized state, the movable rod 4 drives the cover 3 to move to the first position (or the second position); when the electromagnet body 5 is in a reverse energized state, the movable rod 4 drives the cover 3 to move to the second position (or the first position); the permanent magnet is used to maintain the position of the movable rod 4 when the electromagnet body 5 is in a power-off state. This double-holding electromagnet is a linear electromagnet, and its principle is similar to that of a push-pull electromagnet and a circular tubular electromagnet. The biggest difference is that a permanent magnet (not shown in the figure) is placed in the middle position of the electromagnet body 5, and the movable rod 4 can be held when no power is supplied, which is very convenient and energy-saving, thereby reducing the energy consumption of the device.

[0072] Illustratively, the electromagnet assembly and the battery cell 13 are sequentially arranged along the length of the housing, with the electromagnet assembly positioned between the battery cell 13 and the top wall of the housing (specifically, the upper cover 7). The heater 2 is used to heat the aerosol-generating article to generate aerosol. The sequential arrangement of the heater 2 and the battery cell 13 along the width of the housing facilitates a compact arrangement of the components of the aerosol-generating device and improves space utilization within the housing.

[0073] Furthermore, the aerosol generating device also includes a mounting bracket 9, which is located in the housing 1, and the end of the connector 10 away from the heating cavity heater 2 is passed through the cigarette insertion hole 91 of the mounting bracket 9, the electromagnet body 5 of the driving mechanism 5 is arranged on the mounting surface 92 of the mounting bracket 9, and the detection mechanism 8 is arranged on the enclosure 93 of the mounting bracket 9. By adding the mounting bracket 9, the installation and fixation of the various components of the aerosol generating device are facilitated. The mounting bracket 9 is preferably made of PC material with good comprehensive performance. The full name of PC material is polycarbonate, which is a thermoplastic engineering plastic with excellent performance.

[0074] Optionally, the aerosol generating device further includes a detection mechanism 8 for detecting the presence of a cigarette 100 in the cigarette insertion port 102. The addition of the detection mechanism 8 assists the aerosol generating device in determining whether a cigarette 100 is present in the heater 2. Upon detecting the presence of a cigarette 100, the heater 2 is activated to heat the cigarette 100. The detection mechanism 8 can be an inductive or microswitch. This embodiment will be described using an infrared beam detection device comprising an infrared transmitter and an infrared receiver 81 as an example.

[0075] Further, if Figure 2 refer to Figures 6 to 8As shown, the detection mechanism 8 includes an infrared receiver 81 and an infrared transmitter that are spaced apart. The infrared receiver 81 and the infrared transmitter are respectively arranged on the two opposite side walls of the enclosure 93. Two perspective windows 101 are provided on the annular wall of the connector 10. The perspective windows 101 are arranged opposite to the corresponding sensors. Among them, the infrared receiver 81 and the infrared transmitter are respectively connected to the two ends of the FPC connector 82. The FPC connector 82 is provided with a connection hole 821, which can be screwed through the connection hole 821 to the enclosure 93. In this example, the enclosure 93 presents a U-shaped structure, and mounting holes 931 are respectively provided on the two opposite side walls of the enclosure 93. The sensors of the detection mechanism 8 are assembled in the corresponding mounting holes 931. In this embodiment, the material of the connector 10 is preferably high-temperature resistant PEEK material (full name: Polyetheretherketone, Polyetheretherketone, a special engineering plastic with excellent properties such as high-temperature resistance, self-lubrication, easy processing and high mechanical strength), and color powder material is added to prevent light transmission. Two lenses (material PC2805 is preferred) are manufactured on the front and back sides of the cigarette insertion port 102 by two-color injection molding to reduce the number of parts and reduce costs. When the user needs to smoke, the cover 3 is opened, and the infrared transmitter is started at the same time, and the infrared receiver 81 can normally receive the infrared signal emitted by the infrared transmitter. When a cigarette 100 is inserted into the cigarette insertion port 102, the infrared signal is blocked, and the infrared receiver 81 cannot receive the infrared signal. At this time, the heater 2 is started. When the cigarette 100 is pulled out, the infrared signal channel is reopened, and the infrared receiver 81 receives the infrared signal emitted by the infrared transmitter. The heater 2 stops heating and closes the cover 3.

[0076] Further, if Figure 3 As shown, the aerosol generating device further includes a control unit 11 and a button 12. The control unit 11 is configured to control the conductive state of the electromagnet body 5 based on a key signal generated by the button 12. The control unit 11 is disposed within the housing 1, and the button 12 is disposed on a side wall of the housing 1. The drive mechanism, heater 2, detection mechanism 8, and button 12 are all electrically connected to the control unit 11. The battery cell 13 is used to provide power to the electrical components of the aerosol generating device.

[0077] In summary, the working principle of the aerosol generating device in this embodiment is:

[0078] The aerosol generating device is characterized in that it is controlled by the control unit 11 of the device. When the device is not in use, the cover 3 is in a normally closed state under the action of the thrust of the elastic member 6, and the detection mechanism 8 can be put into a dormant state, thereby reducing the standby power consumption of the device and extending the standby time. At this time, the electromagnet body 5 is in a power-off state, and the movable rod 4 is in a far end position away from the electromagnet body 5 under the action of the spring force. Since the movable rod 4 is connected to the mounting slot 321 of the connecting plate 32, the cover 3 can be kept in the closed position unchanged.

[0079] When the user needs to use the device, he only needs to press the button 12 once, and the electromagnet body 5 will be energized immediately. The electromagnet body 5 will generate a magnetic force, attracting the movable rod 4 to move toward the direction of the electromagnet body 5, thereby driving the cover 3 to open. The electromagnet body 5 will remain energized for a period of time (recommended for about 3 seconds) for the user to insert the cigarette 100. When the detection mechanism 8 of the device detects that a cigarette 100 has been inserted, the cover 3 will remain open. When the detection mechanism 8 does not detect that a cigarette 100 has been inserted or detects that the cigarette 100 has been pulled out, the electromagnet body 5 will remain energized for a period of time (recommended for about 3 seconds), the control unit 11 cuts off the current of the electromagnet body 5, the magnetic force of the electromagnet body 5 disappears, and the movable rod 4 moves away from the electromagnet body 5 under the thrust of the elastic member 6, driving the cover 3 to close.

[0080] The aerosol generating device also features a cleaning mode, which can be entered by pressing button 12 repeatedly or continuously. Cover 3 remains open for a long period (recommended 5 to 10 minutes), while detection mechanism 8 is deactivated, causing the heating chamber of the device to enter a dormant state. This facilitates cleaning the interior of heater 2, keeping heater 2 clean and providing a healthy and comfortable puff experience. This aerosol generating device greatly simplifies user operation and improves the convenience and comfort of the user experience.

[0081] At the same time, when the cover 3 is kept closed for a long time, it can prevent children's fingers and other foreign objects from being inserted into the heater 2, avoid the risk of personal injury and fire caused by abnormal heating of the heater, and further improve the safety of the device.

Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
