Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] An aerosol generator is an electronic device that uses electric heating to atomize stored aerosol-generating substances such as e-liquids and medications into aerosols. Currently, commercially available aerosol generators typically include a mouthpiece, a housing, an atomizing module, a control module, and a battery. The mouthpiece is connected to the housing and is used by the user to inhale the aerosol. The housing has a tubular structure with an internal cavity containing the atomizing module, control module, and battery.

[0003] The atomizing module includes a liquid reservoir and an atomizing core. The liquid reservoir typically contains aerosol-generating substances, which are conducted to the atomizing core via capillary action. During inhalation using the aerosol generator, the battery provides power to the atomizing core, causing it to heat up. This heat atomizes the aerosol-generating substances into an inhalable aerosol. However, existing aerosol generators are inconvenient to assemble and do not allow users to easily monitor battery levels. Utility Model Content

[0004] The main objective of this application is to provide an aerosol generating device that is easy to assemble and easy for users to understand.

[0005] To achieve the above objectives, this application provides an aerosol generating device, comprising a housing, a support, an atomizing module, a light guide, a display module, a light-shielding cover, and a light-transmitting cover. The housing is provided with a receiving cavity and a side opening, the side opening being located at the side wall of the receiving cavity and communicating with the receiving cavity; the support is inserted into the receiving cavity and extends out from the side opening; the atomizing module is located in the receiving cavity and connected to the support.

[0006] The light guide is located inside the light-transmitting cover and is connected to one end of the bracket extending outside the side opening. The light guide is provided with a clearance hole and a light-emitting surface surrounding the light guide. The display module includes a first circuit board, a display screen, and several light sources for emitting light toward the light guide. The display screen is positioned corresponding to the clearance hole and is connected to the first circuit board. The display surface of the display screen displays information in a first direction. Several light sources are arranged around the display screen. The light-shielding cover covers the light guide to prevent the light from the light source from emitting in the first direction. The light-transmitting cover is disposed on one end of the bracket extending outside the side opening.

[0007] In one embodiment, the light guide has a receiving groove on the side facing the bracket, and the first circuit board and the light source are located in the receiving groove.

[0010] In one embodiment, the light-shielding cover is provided with a second fastening arm, which passes through the clearance hole and is fastened to the groove wall of the receiving groove.

[0011] In one embodiment, the aerosol generating device further includes a light-blocking sheet connected to the light-shielding cover and covering the clearance hole, wherein the display surface of the display screen faces the light-blocking sheet.

[0012] In one embodiment, the light-blocking sheet has a higher light transmittance than the light-shielding cover.

[0013] In one embodiment, the light transmittance of the light-blocking sheet is less than that of the light-transmitting cover.

[0015] In one embodiment, the aerosol generating device further includes a battery mounted on the bracket and located between the atomizing module and the first circuit board.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: This application achieves the following through the cooperation between the housing, bracket, light guide, display module, light shield, display screen and light-transmitting cover: the housing is provided with a receiving cavity and a side opening, the side opening is located at the side wall of the receiving cavity and communicates with the receiving cavity; the bracket is inserted into the receiving cavity and extends out from the side opening; the light guide is located in the light-transmitting cover and connected to one end of the bracket extending outside the side opening, the light guide is provided with a clearance hole and a light-emitting surface arranged around the light guide; the display module includes a display screen and several light sources for emitting light toward the light guide, the display screen is positioned corresponding to the clearance hole, the display surface of the display screen displays information in a first direction, and several light sources are arranged around the display screen.

[0017] During assembly, the light guide, display module, light shield, and display screen are first mounted onto the bracket, and then the bracket is inserted into the receiving cavity through the side opening, thus facilitating assembly.

[0030] Please refer to Figures 1-8 One embodiment of this application provides an aerosol generating device, which includes a nozzle 1, a housing 2, a support 3, an atomizing module 4, a light guide 5, a display module 6, a light-shielding cover 7, and a light-transmitting cover 8. The nozzle 1 is connected to the housing 2 and extends into the first end of the atomizing module 4, allowing the user to inhale aerosols through the nozzle 1. A condensate absorbent cotton 90 is inserted into the end of the nozzle 1 connected to the atomizing module 4. The condensate absorbent cotton 90 is used to absorb the condensed aerosol generating matrix, thereby reducing the probability of the user inhaling the condensed aerosol generating matrix.

[0031] The housing 2 consists of a top wall, side walls, and a bottom wall, and is a one-piece molded structure. Therefore, it is not only structurally reliable but also reduces production steps and improves production efficiency. The housing 2 is provided with an air inlet 21, a receiving cavity 22, and a side opening 23. The air inlet 21 is located on the bottom wall of the housing 2. When the user inhales the aerosol, external gas flows through the air inlet 21 into the atomizing module 4 to carry the aerosol out of the atomizing module 4. The receiving cavity 22 extends longitudinally along the housing 2. The side opening 23 is located on the side wall of the receiving cavity 22 and communicates with the receiving cavity 22.

[0032] The bracket 3 is inserted into the receiving cavity 22 and extends out from the side opening 23. A notch 31 is provided on one side of the bracket 3 within the receiving cavity 22. The notch 31 extends longitudinally along the bracket 3 and reaches the first end face of the bracket 3. The first end and the second end of the bracket 3 are positioned opposite each other. The bracket 3 also has a fastening groove 32 located on one side of the notch 31.

[0033] The atomizing module 4 is located within the receiving cavity 22 and positioned at the notch 31. The first end of the atomizing module 4 is inserted into the nozzle 1, and the second end of the atomizing module 4 is abutted against the bracket 3. The first and second ends of the atomizing module 4 are positioned opposite each other. It is understood that the atomizing module 4 and the bracket 3 can be directly or indirectly connected; no specific limitation is made here, as long as it can be reliably fixed to the bracket 3. By providing the notch 31 for installing the atomizing module 4, during assembly, the atomizing module 4 is first installed into the notch 31 of the bracket 3, and then the atomizing module 4, along with the bracket 3, is inserted into the receiving cavity 22 through the side opening 23. This not only facilitates assembly but also ensures proper placement.

[0034] The atomizing module 4 includes a liquid storage tube 41, a first elastic sealing seat 42, a second elastic sealing seat 43, a porous suction column 44, and an atomizing core 45. The liquid storage tube 41 is located at the notch 31 and is used to store the aerosol generation matrix. The first elastic sealing seat 42 covers the first end of the liquid storage tube 41 and elastically abuts against the housing 2. One end of the nozzle 1 extends into the first elastic sealing seat 42. The second elastic sealing seat 43 covers the second end of the liquid storage tube 41 and elastically abuts against the support 3 to seal the liquid storage tube 41. The first elastic sealing seat 42 and the second elastic sealing seat 43 can be made of elastic materials such as silicone or rubber. The porous suction column 44 is located inside the liquid storage tube 41 and is used to adsorb the aerosol generation matrix. It can be made of materials such as fiber or porous ceramic.

[0035] The atomizing core 45 is located within the porous liquid-absorbing column 44 and is used to atomize the aerosol generation matrix. It includes a porous liquid-guiding component 451 and a heating element 452. The porous liquid-guiding component 451 is located within and in contact with the porous liquid-absorbing column 44 to conduct the aerosol generation matrix from the porous liquid-absorbing column 44 to the heating element 452. The heating element 452 atomizes the aerosol generation matrix to form an aerosol. When the user inhales, the aerosol generation matrix is ​​atomized at the heating element 452 and flows to the mouthpiece 1, then flows out from the mouthpiece 1. In this embodiment, the atomizing module 4 has a columnar structure, with the first end and the second end of the atomizing module 4 positioned opposite each other. It is understood that as long as the aerosol generation matrix can be atomized, the structure of the atomizing module 4 is not specifically limited here.

[0036] The light guide 5 is located inside the light-transmitting cover 8 and is connected to one end of the bracket 3 extending to the side opening 23. Specifically, the light guide 5 is provided with a first fastening arm 51, a receiving groove 52, a clearance hole 53, and a light-emitting surface 54 surrounding the light guide 5. The first fastening arm 51 is fastened to the fastening groove 32, thus facilitating assembly. The receiving groove 52 is located on the side of the light guide 5 facing the bracket 3, and the clearance hole 53 communicates with the receiving groove 52. The light-emitting surface 54 is located at the outer peripheral edge of the light guide 5 and is roughly rectangular in shape. After the light is emitted from the light-emitting surface 54 and the light-transmitting cover 8, it forms a light-emitting ring surrounding the top wall, bottom wall, and side wall of the aerosol generating device, thus making it easy for users to identify and attract their attention.

[0037] The display module 6 includes a first circuit board 61, a display screen 62, and several light sources 63 for emitting light towards the light guide 5. The first circuit board 61 is located within the receiving groove 52, thus ensuring reliable fixation and preventing it from easily falling off due to vibration or other reasons. The display screen 62 is positioned corresponding to the clearance hole 53 and connected to the first circuit board 61. The display screen 62 extends from the clearance hole 53, thus enabling precise positioning. The display surface of the display screen 62 displays information facing a first direction. In this embodiment, the first direction refers to the direction in which the display surface of the display screen 62 faces away from the display surface of the atomizing module 4. Several light sources 63 are located within the receiving groove 52 and fixed to the first circuit board 61. The light sources 63 are arranged around the display screen 62, with the light sources 63 spaced apart from each other, thus ensuring more uniform light emission from the light guide 5. The groove wall of the receiving groove 52 covers the light sources 63, thus allowing light to penetrate into the light guide 5 as much as possible. Preferably, the first light source 63 is an LED lamp bead.

[0038] A light-shielding cover 7 covers the light guide 5 to prevent light from the light source 63 from escaping in the first direction, thus avoiding eye strain when the user views the display screen 62. A light-transmitting cover 8 is installed on one end of the bracket 3 extending beyond the side opening 23. The light-shielding cover 7 is provided with a second fastening arm 71, which passes through the clearance hole 53 and is fastened to the groove wall of the receiving groove 52. Therefore, the overall structure is compact and easy to assemble. In addition, the light-transmitting cover 8 is also connected to the housing 2. The bracket 3, the light guide 5, and the light-shielding cover 7 are all located within the space formed by the housing 2 and the light-transmitting cover 8. Therefore, the exterior of the aerosol generating device is simpler and less prone to dust accumulation.

[0039] Furthermore, the aerosol generating device in this embodiment also includes a light-blocking plate 91, a battery 92, a connector 93, a control module 94, an airflow sensor 95, a liquid-absorbing plate 96, an air-regulating block 97, a first sealing ring 98, and a second sealing ring 99. The light-blocking plate 91 is connected to the light-shielding cover 7 and covers the clearance hole 53. The display surface of the display screen 62 faces the light-blocking plate 91. By blocking the light emitted from the display screen 62 by the light-blocking plate 91, the light intensity of the display screen 62 can be reduced, resulting in softer light and a better user experience. The light transmittance of the light-blocking plate 91 is greater than that of the light-shielding cover 7, and the light transmittance of the light-blocking plate 91 is less than that of the light-transmitting cover 8. Preferably, the light-blocking plate 91 is made of a translucent material, and the light-transmitting cover 8 is made of a transparent material. Light emitted from the light-emitting surface 54 is emitted through the light-transmitting cover 8. Battery 92 is mounted on bracket 3 and located between atomizing module 4 and first circuit board 61, thus avoiding the influence of leaked aerosol generation matrix and improving its service life. Battery 92 is electrically connected to control module 94.

[0040] The connecting seat 93 is connected to the second end of the atomizing module 4 and the bracket 3. It includes a support plate portion 931, a connecting ring portion 932, and an air guide ring portion 933. The support plate portion 931 is provided with a support surface 9311 and a second air guide hole 9312. The support surface 9311 extends laterally along the atomizing module 4 and abuts against the end face of the second end of the atomizing module 4, that is, the support surface 9311 abuts against the end face of the second elastic sealing seat 43 of the atomizing module 4. In other words, the second elastic sealing seat 43 covers the second end of the liquid storage tube 41 and elastically abuts against the support plate portion 931. The connecting ring portion 932 is connected to the support surface 9311 and extends into the second elastic sealing seat 43 of the atomizing module 4. The air guide ring 933 is located on the side of the support plate 931 facing away from the atomizing module 4. A first air guide hole 9331 is formed in the air guide ring 933. The first air guide hole 9331 communicates with the outside of the housing 2. The second air guide hole 9312 communicates with the first air guide hole 9331 and the atomizing module 4.

[0041] The control module 94 includes a second circuit board 941 and a control chip 942. The second circuit board 941 is located on the side of the connector 93 facing away from the atomizing module 4. The air guide ring 933 extends through the second circuit board 941, thus reducing the probability of aerosol generation matrix leakage from the atomizing module 4 to the control module 94. The control chip 942 is located on the side of the second circuit board 941 facing away from the connector 93 and is electrically connected to the battery 92 and the atomizing core 45. An airflow sensor 95 is mounted on the second circuit board 941 and is electrically connected to the control chip 942. When the user inhales the aerosol, the airflow sensor 95 is triggered and sends a trigger signal to the control chip 942. The control chip 942 then controls the battery 92 to supply power to the atomizing core 45, thereby atomizing the aerosol generation matrix to form an aerosol.

[0042] The absorbent pad 96 is located inside the connecting ring 932 and is used to absorb the aerosol generation matrix leaking from the atomizing module 4. The absorbent pad 96 can be made of cotton or other materials capable of absorbing the aerosol generation matrix. The air regulating block 97 is movably disposed inside the housing 2. The air regulating block 97 is provided with an air regulating hole 971, which is used to guide the airflow from the air inlet 21 into the first air guide hole 9331. The first sealing ring 98 is sleeved on the outer peripheral surface of the air guide ring 933 and elastically abuts against the air regulating block 97, thus effectively preventing air leakage and providing inhalation sensitivity. The second sealing ring 99 is sleeved on the airflow sensor 95 and connected to the first sealing ring 98. The second sealing ring 99 extends into the support plate 931, thus not only effectively sealing the airflow sensor 95, but also allowing the first sealing ring 98 and the second sealing ring 99 to be assembled simultaneously during assembly, improving production efficiency. The first sealing ring 98 and the second sealing ring 99 can be made of elastic materials such as silicone or rubber.

[0043] In summary, this application utilizes the cooperation between the housing 2, bracket 3, light guide 5, display module, light shield 7, display screen 62, and light-transmitting cover 8. The housing 2 is provided with a receiving cavity 22 and a side opening 23. The side opening 23 is located at the side wall of the receiving cavity 22 and communicates with the receiving cavity 22. The bracket 3 is inserted into the receiving cavity 22 and extends out from the side opening 23. The light guide 5 is located inside the light-transmitting cover 8 and is connected to one end of the bracket 3 extending outside the side opening 23. The light guide 5 is provided with a clearance hole 53 and a light-emitting surface 54 surrounding the light guide 5. The display module 6 includes a display screen 62 and several light sources 63 for emitting light toward the light guide 5. The display screen 62 is positioned corresponding to the clearance hole 53. The display surface of the display screen 62 displays information in a first direction. Several light sources 63 are arranged around the display screen 62.

[0044] During assembly, the light guide 5, display module, light shield 7, and display screen 62 are first installed onto the bracket 3, and then the bracket 3 is inserted into the receiving cavity 22 through the side opening 23, thus facilitating assembly. Furthermore, since several light sources 63 are arranged around the display screen 62 and emit light towards the light guide 5, the light is emitted from the light-emitting surface 54 surrounding the light guide 5. Therefore, regardless of how the user holds the housing 2, the location of the display screen 62 is clearly indicated, allowing the user to understand relevant information about the electronic cigarette. Finally, since the light shield 7 covers the light guide 5, it prevents the light from the light sources 63 from emitting in the first direction. Therefore, it avoids glare when viewing the information on the display screen 62, better protecting the user's eyes.
