Description

Technical Field

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

[0002] Aerosol-generating devices, typically consisting of an atomizer and a power supply, are widely used in the market. The atomizer typically includes a liquid reservoir and an atomizer assembly. The liquid reservoir stores the atomizable medium, while the atomizer assembly heats and atomizes the atomizable medium to form an aerosol for the user. The power supply provides the necessary energy for the atomizer assembly to function properly.

[0003] With technological advancements and rising user demands, more and more aerosol generating devices are integrating displays to provide more functionality and a better user experience. However, most aerosol generating devices with screens currently on the market typically use non-flexible screens. These screens require adaptive design based on their size and shape, and typically can only be placed on one side of the product. This limits product design flexibility and aesthetics, and fails to meet user demand for larger screens.

[0004] The above information disclosed in the background of this application is only used to understand the background of the concept of this application, and does not indicate or suggest that it contains information of the prior art. Utility Model Content

[0005] Based on this, it is necessary to provide an aerosol generating device to address the above problems.

[0006] An aerosol generating device comprising:

[0007] case;

[0008] An outer bracket, the outer bracket is arranged in the shell, and a limiting groove is provided on the outer peripheral surface of the outer bracket, and the limiting groove extends along the circumference of the outer bracket;

[0009] a curved display element, the curved display element being embedded in the limiting groove, the light-emitting surface of the curved display element facing the housing, and at least a portion of the housing covering the curved display element being a transparent housing;

[0010] an atomizing device, the atomizing device being disposed in the outer support and being used to generate an aerosol;

[0011] a power supply device disposed in the housing and electrically connected to the atomizing device and the curved display element;

[0012] a circuit board, the circuit board being electrically connected to the atomizing device and the power supply device;

[0013] Among them, an opening is opened through the outer circumference of the outer bracket, and the opening is connected to the limiting groove. The curved display component includes a flexible curved screen and a connecting component. The flexible curved screen is embedded in the limiting groove. One end of the connecting component is electrically connected to the flexible curved screen, and the other end of the connecting component passes through the opening to be electrically connected to the circuit board.

[0014] The above-mentioned aerosol generating device can achieve at least the following beneficial effects:

[0015] The aerosol generating device features a retaining groove extending along the circumference of the outer bracket. The curved display element can be bent and deformed to conform to the shape of the retaining groove, allowing the curved display element to be embedded within the retaining groove of the outer bracket, with the light-emitting surface of the curved display element facing the housing. This structural design significantly increases the display area, enabling a larger screen display. This not only allows for displaying more information about the aerosol generating device's status (such as battery level, output power, remaining puff volume, remaining atomized medium volume, lighting, and graphics), but also enhances the product's aesthetics, meeting user demands for larger, clearer displays.

[0016] Furthermore, the retaining groove secures and protects the curved display mounted therein. Since the outer bracket is positioned within the housing, which also covers the curved display, shielding it from the retaining groove, this prevents foreign objects from directly contacting the light-emitting surface of the curved display and causing damage, ensuring the long-term, normal, and effective operation of the curved display and extending its service life. The outer bracket protects the circuit board, and the opening in the outer bracket provides a passage for the connector on the outer periphery of the outer bracket to extend into the flexible curved screen. Specifically, the connector extends through the opening, with its ends connected to the flexible curved screen and the circuit board, respectively.

[0017] In one embodiment, the outer circumference of the outer bracket is provided with a first limiting rib and a second limiting rib. Both the first limiting rib and the second limiting rib abut the inner circumference of the housing. The first limiting rib and the second limiting rib extend circumferentially along the outer bracket and are spaced apart axially along the outer bracket. The first limiting rib, the second limiting rib, and the outer circumference of the outer bracket together form the limiting groove, and the first limiting rib and the second limiting rib respectively abut opposite side edges of the curved display element. The first limiting rib and the second limiting rib provided on the outer circumference of the outer bracket together form the limiting groove, effectively utilizing the internal space layout of the device and making the device structure more compact and reasonable. The first limiting rib and the second limiting rib respectively abut opposite side edges of the curved display element, ensuring that the curved display element is firmly fixed in the limiting groove and preventing it from shifting or falling off during use.

[0018] In one embodiment, the circuit board is disposed in the outer bracket.

[0019] In one embodiment, the thickness of the flexible curved screen is less than the depth of the retaining groove. Because the thickness of the flexible curved screen is less than the depth of the retaining groove, the surface of the flexible curved screen does not protrude beyond the retaining groove after being inserted into the retaining groove. The depth of the retaining groove is greater than the thickness of the flexible curved screen. This design can effectively protect the surface of the flexible curved screen, preventing the inner surface of the housing from being scratched or damaged by external forces during use. It also allows the flexible curved screen to have a certain amount of space to move within the retaining groove. This design helps to buffer external vibration and impact, improve the stability and durability of the flexible curved screen, and prevent it from shifting or falling off due to changes in the external environment.

[0020] In one embodiment, the aerosol generating device further includes a support structure and an inner bracket, the atomizing device is arranged in the inner bracket, the circuit board is arranged below the atomizing device, the inner bracket is arranged in the outer bracket, the opening is close to the bottom end of the outer bracket, the support structure is protruded on the side of the inner bracket facing the opening, the support structure has a support top surface and a support side surface, the support top surface and part of the outer peripheral surface of the inner bracket and part of the inner peripheral surface of the outer bracket are enclosed to form a accommodating cavity, the power supply device is arranged in the accommodating cavity, and the support top surface is used to support the power supply device. By forming an accommodating cavity between the inner bracket and the outer bracket, the internal space of the device is effectively utilized, making the overall structure more compact, the support top surface of the support structure can support the power supply device thereon, and combined with the inner wall of the accommodating cavity, it has a better fixing effect on the power supply device.

[0021] In one embodiment, the curved display element further includes a controller, which is located on the supporting side surface, with the supporting side surface facing the opening. One end of the connector is electrically connected to the flexible curved screen via the controller, and the controller is used to control the flexible curved screen to display status information of the aerosol generating device. This structural design also prevents the controller from being disturbed by touch and affecting its normal function. Furthermore, the proximity of the opening to the control circuit board helps reduce the length of the connector, simplifying the wiring and installation of electrical connections, allowing for more rational internal space organization and improved assembly efficiency, resulting in a more compact overall structure, avoiding additional space occupation, and improving the space utilization efficiency of the device.

[0022] In one embodiment, the aerosol generating device further includes a support protrusion, wherein the support protrusion is provided on either the inner peripheral surface of the outer bracket or the outer peripheral surface of the inner bracket, and the support protrusion abuts against the other of the inner peripheral surface of the outer bracket and the outer peripheral surface of the inner bracket to limit the movement between the outer bracket and the inner bracket. The provision of the support protrusion simplifies the installation process of the inner bracket and the outer bracket, and a stable connection can be achieved without an additional fixing device, which is beneficial to improving production efficiency and reducing installation time and cost. The support protrusion limits the relative movement between the inner bracket and the outer bracket through the abutment effect, thereby enhancing the overall structural stability of the device, reducing friction and wear between components, and helping to extend the service life of the device.

[0023] In one embodiment, the aerosol generating device further comprises an upper seal, wherein a limiting protrusion is provided on the top of the inner bracket, a limiting recess is provided in the outer bracket that matches the limiting protrusion, the limiting protrusion is inserted into the limiting recess to limit the movement between the outer bracket and the inner bracket, and the upper seal is provided between the limiting protrusion and the limiting recess.

The upper seal provides additional sealing protection, ensures the stability of the internal environment of the device, and further improves the overall performance of the device and user experience.

[0024] In one embodiment, the aerosol generating device further comprises a nozzle, which is provided on the shell, and an air outlet of the nozzle passes through the shell, the outer bracket, and the inner bracket to communicate with the atomization chamber of the atomization device.

[0025] In one embodiment, the atomization device includes a ventilation tube, an atomization assembly and a storage piece arranged in the inner bracket. The storage piece is sleeved on the ventilation tube, so the storage piece is used to store the atomization matrix and supply the atomization matrix into the ventilation tube. The ventilation tube encloses the atomization cavity, and the atomization assembly is arranged in the atomization cavity and is used to atomize the atomization matrix to form an aerosol.

[0026] In one embodiment, the aerosol generating device includes a button and a bottom cover provided on the bottom of the shell, an operation port is provided on the bottom cover, the button includes a functional end and an operation end connected to the functional end, the operation end is provided through the operation port for operation, and the functional end is connected to the circuit board to change at least one status information displayed on the flexible curved screen when a preset operation is received.

The functional end of the button is connected to the circuit board, and a variety of functional operations can be realized. For example, the user can use the button to adjust the flexible curved screen to display different status information, such as battery power, working mode, temperature setting, etc. After receiving the preset operation signal of the button, the flexible curved screen will update the display content in a timely manner to ensure that the user understands the status of the device in real time.

The air inlet bracket is embedded in the bottom of the inner bracket and shielding the atomizing device, thereby protecting the atomizing device from direct influence of external substances. The air intake bracket, located between the atomizer and the circuit board, provides isolation, preventing liquid or gas from the atomizer from affecting the circuit board's operation. The design of the retaining bosses and retaining holes secures the circuit board in place, preventing it from loosening or shifting due to equipment movement or vibration.

DETAILED DESCRIPTION

[0045] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] See also Figures 1 to 6 In some embodiments, the present application provides an aerosol generating device 10, which includes a housing 100, an outer bracket 200, a curved display 300, an atomizing device 400, a power supply 500, and a circuit board 600. The outer bracket 200 is disposed in the housing 100, as shown in FIG. Figure 5 As shown, a limiting groove 230 is provided on the outer peripheral surface of the outer bracket 200, and the limiting groove 230 extends along the circumference of the outer bracket 200. Figure 3 and Figure 6 As shown, the curved display part 300 is embedded in the limiting groove 230, the light-emitting surface of the curved display part 300 faces the shell 100, and at least the part of the shell 100 covering the curved display part 300 is a transparent shell 100. In other words, the shell 100 can also be transparent as a whole, which is not limited here. It is only necessary that the shell 100 can satisfy the light from the light-emitting surface of the curved display part 300 to pass through. The atomizing device 400 is arranged in the outer bracket 200 and can atomize the atomizing matrix to generate an aerosol. Among them, the atomizing matrix can refer to a material that can be atomized to provide aerosol components under certain conditions, such as the atomizing matrix can be one or more of tobacco oil, tobacco liquid, tobacco, tobacco derivatives, or tobacco substitutes. The power supply device 500 is arranged in the shell 100 and is electrically connected to the atomizing device 400 and the curved display part 300. The circuit board 600 is arranged in the outer bracket 200 and is electrically connected to the atomization device 400 and the power supply device 500. An opening 240 is opened through the outer circumference of the outer bracket 200, and the opening 240 is connected to the limiting groove 230. The curved display component 300 includes a flexible curved screen 310 and a connecting component 320. The flexible curved screen 310 is embedded in the limiting groove 230. One end of the connecting component 320 is electrically connected to the flexible curved screen 310, and the other end of the connecting component 320 passes through the opening 240 to be electrically connected to the circuit board 600.

[0047] The above-mentioned aerosol generating device 10 can achieve at least the following beneficial effects:

[0048] The limiting groove 230 of the aerosol generating device 10 extends along the circumference of the outer bracket 200. The curved display element 300 can be bent and deformed to adapt to the shape of the limiting groove 230, thereby embedding the curved display element 300 in the limiting groove 230 of the outer bracket 200, with the light-emitting surface of the curved display element 300 facing the housing 100. This structural design greatly increases the display area, enabling a larger screen display. This can not only display more status information about the aerosol generating device 10 (such as battery level, output power, remaining puff volume, remaining atomized medium volume, lighting, patterns, etc.), but also enhance the product's aesthetics and meet users' demand for larger and clearer display screens.

[0049] Furthermore, the retaining groove 230 secures and protects the curved display 300 mounted therein. Since the outer bracket 200 is disposed within the housing 100, the housing 100 also covers the curved display 300, obscuring the retaining groove 230. This prevents foreign objects from directly contacting the light-emitting surface of the curved display 300 and causing damage, ensuring the long-term, normal, and effective operation of the curved display 300 and extending its service life. The outer bracket 200 protects the circuit board 600 located therein. The opening 240 on the outer bracket 200 provides a passage for the connector 320, which is located on the outer periphery of the outer bracket 200 and is connected to the flexible curved screen 310. Specifically, the connector 320 extends through the opening 240, with its ends connected to the flexible curved screen 310 and the circuit board 600, respectively.

[0050] Specifically, if Figure 6 and Figure 7 As shown, in some embodiments, a first limiting rib 210 and a second limiting rib 220 are provided on the outer circumferential surface of the outer bracket 200, and the first limiting rib 210 and the second limiting rib 220 are both in contact with the inner circumferential surface of the shell 100, and the first limiting rib 210 and the second limiting rib 220 are both extended along the circumference of the outer bracket 200, and the first limiting rib 210 and the second limiting rib 220 are spaced apart along the axial direction of the outer bracket 200, and the first limiting rib 210, the second limiting rib 220 and the outer circumferential surface of the outer bracket 200 enclose the limiting groove 230, and the first limiting rib 210 and the second limiting rib 220 are respectively in contact with the two opposite side edges of the curved display part 300. The first and second limiting ribs 210, 220, provided on the outer circumference of the outer bracket 200, enclose the limiting groove 230, effectively utilizing the internal space of the device and making the device structure more compact and reasonable. The first and second limiting ribs 210, 220 respectively abut the opposite side edges of the curved display element 300, ensuring that the curved display element 300 is firmly fixed in the limiting groove 230, preventing it from shifting or falling off during use.

[0051] Specifically, if Figure 3 、 Figure 4 and Figure 5As shown, in some embodiments, the thickness of the flexible curved screen 310 is less than the depth of the limiting groove 230. Because the thickness of the flexible curved screen 310 is less than the depth of the limiting groove 230, the surface of the flexible curved screen 310 does not protrude beyond the limiting groove 230 after being inserted into the limiting groove 230. The depth of the limiting groove 230 is greater than the thickness of the flexible curved screen 310. This design can effectively protect the surface of the flexible curved screen 310, preventing the inner surface of the housing 100 from scratching or damaging the flexible curved screen 310 due to external forces during use. It also allows the flexible curved screen 310 to have a certain amount of space to move within the limiting groove 230. This design helps to buffer external vibration and impact, improve the stability and durability of the flexible curved screen 310, and prevent it from displacement or falling off due to changes in the external environment.

[0052] Specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the aerosol generating device 10 further includes a supporting structure 710 and an inner bracket 700, the atomizing device 400 is arranged in the inner bracket 700, the circuit board 600 is arranged below the atomizing device 400, the inner bracket 700 is arranged in the outer bracket 200, the opening 240 is close to the bottom end of the outer bracket 200, the supporting structure 710 is protruded on the side of the inner bracket 700 facing the opening 240, the supporting structure 710 has a supporting top surface 711 and a supporting side surface 712, the supporting top surface 711 and part of the outer peripheral surface of the inner bracket 700 and part of the inner peripheral surface of the outer bracket 200 enclose a accommodating cavity 250, the power supply device 500 is arranged in the accommodating cavity 250, and the supporting top surface 711 is used to support the power supply device 500. By forming a accommodating cavity 250 between the inner bracket 700 and the outer bracket 200, the internal space of the equipment is effectively utilized, making the overall structure more compact. The supporting top surface 711 of the supporting structure 710 can support the power supply device 500 thereon, and combined with the inner wall of the accommodating cavity 250, it can better fix the power supply device 500.

[0053] Specifically, if Figure 3 and Figure 5As shown, in some embodiments, the curved display member further includes a controller 330, which is disposed on the supporting side surface 712, with the supporting side surface 712 facing the opening 240. One end of the connector 320 is electrically connected to the flexible curved screen 310 via the controller 330. The controller 330 is used to control the flexible curved screen 310 to display status information of the aerosol generating device 10. This structural design also prevents the controller 330 from being disturbed by touch and affects its normal function. In addition, the opening 240 is located near the control circuit board 600, which helps reduce the length of the connector 320, simplifies the wiring and installation of electrical connections, and allows for more rational internal space arrangement and improved assembly efficiency, making the overall structure more compact, avoiding additional space occupation, and improving the space utilization efficiency of the device.

[0054] See also Figure 7 In some embodiments, the aerosol generating device 10 further includes a support protrusion 260, which is provided on either the inner circumferential surface of the outer bracket 200 or the outer circumferential surface of the inner bracket 700, and the support protrusion 260 abuts against the other of the inner circumferential surface of the outer bracket 200 and the outer circumferential surface of the inner bracket 700 to limit the movement between the outer bracket 200 and the inner bracket 700. The provision of the support protrusion 260 simplifies the installation process of the inner bracket 700 and the outer bracket 200, and a stable connection can be achieved without an additional fixing device, which is conducive to improving production efficiency and reducing installation time and cost. The support protrusion 260 limits the relative movement between the inner bracket 700 and the outer bracket 200 through the abutment effect, thereby enhancing the overall structural stability of the device, reducing friction and wear between components, and helping to extend the service life of the device.

[0055] See also Figure 3 、 Figure 6 、 Figure 8 and Figure 9In some embodiments, the aerosol generating device 10 includes a button 120 and a bottom cover 110 disposed on the bottom of the housing 100. The bottom cover 110 defines an operation port 111. The button 120 includes a functional end 121 and an operating end 122 connected to the functional end 121. The operating end 122 extends through the operation port 111 for operation. The functional end 121 is connected to the circuit board 600 to change at least one status information displayed on the flexible curved screen 310 upon receiving a preset operation. The operation port 111 provided on the bottom cover 110 and the operating end 122 extending through the operation port 111 make operation of the button 120 more intuitive and convenient, facilitating user operation. The functional end 121 of the button 120 is connected to the circuit board 600 and can perform multiple functional operations. For example, the user can use the button 120 to adjust the status information displayed on the flexible curved screen 310, such as battery level, operating mode, and temperature setting. After receiving the preset operation signal of the button 120, the flexible curved screen 310 will update the display content in time to ensure that the user understands the device status in real time. Among them, the preset operation can include one or more of pressing, touching, sliding, rotating and the like.

[0056] Furthermore, if Figure 3 and Figure 9As shown, in some embodiments, the aerosol generating device 10 includes an air regulating member 840 and an air inlet bracket 850, the air inlet bracket 850 is embedded in the bottom of the inner bracket 700 and blocks the atomizing device 400 in the inner bracket 700, the air inlet bracket 850 is located between the atomizing device 400 and the circuit board 600, and the air inlet bracket 850 is provided with a limiting boss 852 on the side facing away from the atomizing device 400, and a first air inlet channel 851 communicating with the atomizing chamber 411 of the atomizing device 400 is provided on the limiting boss 852, and a limiting hole 610 is provided on the circuit board 600. The circuit board 600 is mounted on the outer circumference of the limiting boss 852 through the limiting hole 610. The air regulating member 840 defines a second air inlet channel 842, and the bottom cover 110 defines an air inlet chute 112. The air regulating member 840 is slidably disposed within the air inlet chute 112 and can slide relative to the first air inlet channel 851 to a first position and a second position. In the first position, the first air inlet channel 851 can communicate with the outside world through the second air inlet channel 842 and the air inlet chute 112. In the second position, the air regulating member 840 blocks the first air inlet channel 851. The air inlet bracket 850 is embedded in the bottom of the inner bracket 700 and blocks the atomizer 400, protecting it from direct impact from external substances. The air inlet bracket 850 is located between the atomizer 400 and the circuit board 600, providing isolation and preventing liquid or gas from the atomizer 400 from affecting the normal operation of the circuit board 600. The design of the retaining boss 852 and retaining hole 610 ensures the securement of the circuit board 600, preventing it from loosening or shifting due to movement or vibration of the device. The user can slide the air control element 840 to select the first or second position as needed, thereby controlling the opening and closing of the air intake channel.
