Description

Technical Field

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

[0002] A vapor generator is an electronic device that can atomize the stored atomizing liquid into vapor by electric heating. Currently, vapor generators on the market typically include a shell, a vapor forming module, a control module, and a battery. The shell is tubular and has a receiving cavity inside, where the vapor forming module, control module, and battery are all installed.

[0003] The vapor-generating module includes a liquid storage tank and an atomizing core. The liquid storage tank typically contains vapor-generating material, which is conducted to the atomizing core via capillary action. During inhalation using the vapor-generating device, the battery provides power to the atomizing core, causing it to heat up. This heat atomizes the vapor-generating material onto the core into vapor that the user can inhale. However, existing vapor-generating devices are inconvenient to assemble, and the battery and other electronic components are susceptible to damage from leaking atomizing liquid, resulting in a short lifespan.

[0008] In one embodiment, the control module includes a first circuit board and a control chip, wherein the first circuit board is located on the side of the connector facing away from the vapor forming module, and the control chip is located on the side of the first circuit board facing away from the connector.

[0009] In one embodiment, the connecting seat includes a support plate portion and a connecting ring portion. The support plate portion is provided with a support surface, which abuts against the second end face of the vapor forming module. The connecting ring portion is connected to the support surface and extends into the vapor forming module.

[0010] In one embodiment, the vapor generating device further includes a liquid suction plate, the support surface is arranged to extend laterally along the vapor forming module, and the liquid suction plate is located inside the connecting ring portion.

[0011] In one embodiment, the connector further includes an air guide ring, which is located on the side of the support plate facing away from the vapor forming module and extends through the first circuit board. A first air guide hole is formed in the air guide ring, which communicates with the outside of the housing. The support plate is provided with a second air guide hole, which communicates with the first air guide hole and the vapor forming module.

[0012] In one embodiment, the vapor generating device further includes an air regulating block and a first sealing ring. The outer shell is provided with an air inlet. The air regulating block is movably disposed within the outer shell and is provided with an air regulating hole. The air regulating hole is used to guide the airflow at the air inlet into the first air guide hole. The first sealing ring is sleeved on the outer peripheral surface of the air guide ring and elastically abuts against the air regulating block.

[0013] In one embodiment, the vapor-forming module includes a liquid storage tube, a first elastic sealing seat, a second elastic sealing seat, a porous liquid-absorbing column, and an atomizing core. The first elastic sealing seat covers the first end of the liquid storage tube and elastically abuts against the outer shell; the second elastic sealing seat covers the second end of the liquid storage tube and elastically abuts against the support plate; the porous liquid-absorbing column is located inside the liquid storage tube and is used to absorb the atomizing liquid; the atomizing core is located inside the porous liquid-absorbing column and is used to atomize the atomizing liquid.

The second sealing ring extends into the support plate portion.

[0015] Compared with the prior art, the advantages of this application are as follows: First, because the outer casing is provided with a receiving cavity and an insertion interface located on the side wall of the outer casing, and a clearance notch is provided on one side of the fixing frame, the clearance notch extends longitudinally along the fixing frame and extends to the first end face of the fixing frame. Therefore, during assembly, the atomizing module is first installed onto the fixing frame, and then the fixing frame is inserted into the receiving cavity through the insertion interface, thus facilitating assembly. Second, because the display module is located outside the outer casing and connected to the fixing frame, and the battery is installed at the fixing frame and located between the atomizing module and the display module, it prevents the atomizing liquid leaking during use from flowing into the battery and the display module, thereby improving service life. Finally, because the outer casing is a one-piece molded structure, the structure is reliable and the service life is long. Attached Figure Description

[0028] Please refer to Figures 1-8 One embodiment of this application provides a vapor generating device, which includes a nozzle 1, a housing 2, a mounting frame 3, a vapor forming 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 vapor forming module 4, allowing the user to inhale the vapor. A condensate absorbent cotton 90 is inserted into the end of the nozzle 1 connected to the vapor forming module 4. The condensate absorbent cotton 90 is used to absorb the condensed atomized liquid, thereby reducing the probability of the user inhaling the condensed atomized liquid.

[0029] The outer casing 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 outer casing 2 is provided with an air inlet 21, a receiving cavity 22, and an insertion interface 23 located on the side wall of the outer casing 2. The air inlet 21 is located on the bottom wall of the outer casing 2. When the user inhales the aerosol, external gas flows through the air inlet 21 into the aerosol forming module 4 to carry out the aerosol within the aerosol forming module 4. The receiving cavity 22 extends longitudinally along the outer casing 2. The insertion interface 23 is located on the side wall of the receiving cavity 22 and communicates with the receiving cavity 22.

[0030] The fixing bracket 3 is inserted into the receiving cavity 22 and extends from the insertion interface 23. A clearance notch 31 is provided on one side of the fixing bracket 3 within the receiving cavity 22. The clearance notch 31 extends longitudinally along the fixing bracket 3 and reaches the first end face of the fixing bracket 3. The first end and the second end of the fixing bracket 3 are positioned opposite each other. The fixing bracket 3 also has a fastening groove 32 located on one side of the clearance notch 31.

[0031] The mist-forming module 4 is located within the receiving cavity 22 and positioned at the clearance notch 31. The first end of the mist-forming module 4 is inserted into the nozzle 1, and the second end is abutted against the mounting bracket 3, ensuring a secure and reliable connection. The first and second ends of the mist-forming module 4 are positioned opposite each other. It is understood that the mist-forming module 4 and the mounting bracket 3 can be directly or indirectly connected; no specific limitation is made, as long as it can be reliably fixed to the mounting bracket 3. By providing the clearance notch 31 for installing the mist-forming module 4, during assembly, the mist-forming module 4 is first installed into the clearance notch 31 of the mounting bracket 3, and then the mist-forming module 4, along with the mounting bracket 3, is inserted into the receiving cavity 22 through the insertion port 23. This not only facilitates assembly but also ensures proper placement.

[0032] The vapor-forming 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 clearance notch 31 and is used to store the atomizing liquid. The first elastic sealing seat 42 covers the first end of the liquid storage tube 41 and elastically abuts against the outer shell 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 fixing frame 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 atomizing liquid. It can be made of materials such as fiber or porous ceramic.

[0033] The atomizing core 45 is located within the porous liquid-absorbing column 44 and is used to atomize the atomized liquid. It includes a porous liquid-guiding component 451 and a heating element 452. The porous liquid-guiding component 451 is located within the porous liquid-absorbing column 44 and contacts the column to conduct the atomized liquid to the heating element 452. The heating element 452 atomizes the atomized liquid to form vapor. When the user inhales, the atomized liquid flows to the mouthpiece 1 after being atomized at the heating element 452, and then flows out from the mouthpiece 1. In this embodiment, the vapor-forming module 4 has a columnar structure, with its first end and second end positioned opposite each other. It is understood that as long as the atomized liquid can be atomized, the structure of the vapor-forming module 4 is not specifically limited here.

[0034] The light guide 5 is located inside the light-transmitting cover 8 and is connected to one end of the fixing frame 3 extending to the insertion interface 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 fixing frame 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 mist generating device, thus making it easy for users to identify and attract their attention.

[0035] The display module 6 includes a second circuit board 61, a display screen 62, and several light sources 63 for emitting light towards the light guide 5. The second 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 second 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 vapor forming module 4. Several light sources 63 are located within the receiving groove 52 and fixed on the second 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.

[0036] 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 mounted on the end of the mounting bracket 3 that extends beyond the insertion interface 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 outer shell 2. The mounting bracket 3, the light guide 5, and the light-shielding cover 7 are all located within the space formed by the outer shell 2 and the light-transmitting cover 8. Therefore, the exterior of the mist generating device is simpler and less prone to dust accumulation.

[0037] Furthermore, the vapor generation device of this embodiment also includes a light-blocking plate 91, a battery 92, a connecting base 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 is positioned facing 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 the mounting bracket 3 and located between the atomizing module 4 and the second circuit board 61, thus avoiding the influence of leaking atomizing liquid and improving its service life. Battery 92 is electrically connected to the control module 94.

[0038] The connecting seat 93 is connected to the second end of the vapor forming module 4 and the fixing frame 3. It includes a support plate portion 931, a connecting ring portion 932, and a gas guiding ring portion 933. The support plate portion 931 is provided with a support surface 9311 and a second gas guiding hole 9312. The support surface 9311 extends laterally along the vapor forming module 4 and abuts against the end face of the second end of the vapor forming module 4. That is, the support surface 9311 abuts against the end face of the second elastic sealing seat 43 of the vapor forming 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 vapor forming module 4. The air guide ring 933 is located on the side of the support plate 931 facing away from the vapor forming module 4. A first air guide hole 9331 is formed in the air guide ring 933. The first air guide hole 9331 is connected to the outside of the outer shell 2. The second air guide hole 9312 is connected to the first air guide hole 9331 and the vapor forming module 4.

[0039] The control module 94 includes a first circuit board 941 and a control chip 942. The first 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 first circuit board 941, thus reducing the probability of atomized liquid leakage from the atomizing module 4 to the control module 94. The control chip 942 is located on the side of the first 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 first circuit board 941 and is electrically connected to the control chip 942. When the user inhales the atomized liquid, 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 atomized liquid to form atomized liquid.

[0040] The absorbent pad 96 is located inside the connecting ring 932 and is used to absorb the atomized liquid leaking from the vapor forming module 4. The absorbent pad 96 can be made of cotton or other materials capable of absorbing atomized liquid. 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.

[0041] 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 casing 2, the area where the display screen 62 is located can be clearly indicated, allowing the user to understand relevant information about the electronic cigarette. Furthermore, 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.

[0042] In summary, firstly, because the outer casing 2 has a receiving cavity 22 and an insertion interface 23 located on the side wall of the outer casing 2, and the mounting bracket 3 has a clearance notch 31 on one side, which extends longitudinally along the mounting bracket 3 and extends to the first end face of the mounting bracket 3, during assembly, the atomizing module 4 is first installed onto the mounting bracket 3, and then the mounting bracket 3 is inserted into the receiving cavity 22 through the insertion interface 23, thus facilitating assembly. Secondly, because the display module 4 is located outside the outer casing 2 and connected to the mounting bracket 3, and the battery 92 is installed at the mounting bracket 3 and located between the atomizing module 4 and the display module 6, it prevents the atomizing liquid from leaking into the battery 92 and the display module 6 during use, thereby improving service life. Finally, because the outer casing 2 is a one-piece molded structure, it is structurally reliable and has a long service life.

[0043] It should be noted that other details of the vapor generation device disclosed in this application can be found in the prior art, and will not be repeated here.

[0044] The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
