Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomizers, and particularly relates to an electronic atomizer.

Background Art

[0002] The working principle of an electronic atomizer is to heat the atomization liquid to a high enough temperature through a heating resistance wire (or heater) to evaporate it into an inhalable gas. When the atomization liquid is heated, its components will evaporate into a gaseous state. However, when these gases encounter a cooled surface, such as the mouthpiece or the smoke outlet channel of the electronic atomizer, they will quickly cool and condense into a liquid, forming condensate inside the electronic atomizer. Especially after the user inhales, the temperature of the gas flowing through the mouthpiece drops rapidly, causing the vapor to condense into a liquid.

[0003] However, in existing electronic atomizer products, the treatment of condensate is mostly to place a cotton core or cotton sheet with good absorption performance near the air flow channel or the mouthpiece. However, the position and structural design of the existing absorption cotton are improper, and the condensate cannot be fully absorbed. It is very likely that the condensate will flow inside the electronic atomizer. Even more seriously, it may cause the condensate to flow out from the air flow channel of the mouthpiece, affecting the normal use of the user.

Content of the Utility Model

[0004] To solve the technical problem of insufficient absorption of condensate in existing electronic atomizers, the utility model provides an electronic atomizer.

[0005] The solution of the utility model to solve the technical problem is to provide an electronic atomizer, which includes a housing and an atomization component arranged in the housing. An atomization channel is arranged in the atomization component; the electronic atomizer further includes a mouthpiece. One end of the mouthpiece extends into the housing and is communicated with the atomization channel. A mouthpiece hole is formed in the mouthpiece. An absorption cotton is arranged between the mouthpiece and the atomization component. An absorption cotton perforation is formed in the absorption cotton. The atomization channel, the absorption cotton perforation and the mouthpiece hole are communicated in sequence. An upper sealing member is further arranged between the mouthpiece and the atomization component. The upper sealing member seals the gap between the absorption cotton and the atomization component; a through hole is formed in the upper sealing member corresponding to the absorption cotton perforation. The inner diameter of the absorption cotton perforation is larger than that of the through hole in at least one direction. The inner walls of the through hole and the absorption cotton perforation are offset in this direction to form a step.

[0006] Preferably, the electronic atomizer further includes a smoke tube. Part of the smoke tube extends into the absorption cotton perforation. A distance is left between the upper end of the smoke tube and the top of the absorption cotton perforation. A liquid storage tank is formed between at least part of the inner wall of the smoke tube and the absorption cotton perforation.

[0007] Preferably, the absorbent cotton includes a first absorbent cotton and a second absorbent cotton, the first absorbent cotton and the second absorbent cotton are stacked, and the cross-sectional area of the second absorbent cotton is larger than that of the first absorbent cotton.

[0008] Preferably, a stop surface is defined near the nozzle hole and facing the mist outlet passage in the nozzle, and a sealing gasket is provided between the absorbent cotton and the stop surface.

[0009] Preferably, a sealing gasket opening is provided on the sealing gasket corresponding to the nozzle hole, and the sealing gasket opening communicates the nozzle hole with the absorbent cotton perforation.

[0010] Preferably, a cavity is provided in the lower part of the nozzle, defined as a receiving cavity, the receiving cavity communicates with the nozzle hole, and the absorbent cotton is arranged in the receiving cavity.

[0015] Compared with the prior art, the electronic atomizer provided by the present utility model has the following advantages:

[0016] In the electronic atomizer provided in the embodiment of the present utility model, the absorbent cotton is arranged between the atomization component and the nozzle of the electronic atomizer. When the user inhales, the hot atomized liquid vapor will flow through the absorbent cotton through the mist outlet passage, and the hot atomized liquid vapor condenses into condensate at the nozzle. The absorbent cotton absorbs the condensate, preventing it from entering the user's mouth through the nozzle hole, and also preventing the condensate from flowing into the interior of the atomization component. An absorbent cotton perforation is provided inside the absorbent cotton, connecting the mist outlet passage, the absorbent cotton and the nozzle hole in sequence. The smoke can smoothly pass through the absorbent cotton. The step between the absorbent cotton and the upper sealing member slows down the flow rate of the condensate in the absorbent cotton perforation, does not hinder the flow of the atomized liquid vapor, and fully adsorbs the condensate so that the condensate is not easily refluxed; the inner diameter of the absorbent cotton perforation in at least one direction is larger than the through hole, which can enable the absorbent cotton to exert a certain pressure on the upper sealing member, promoting a tighter engagement between the upper sealing member and the absorbent cotton.

[0033] Please refer to Figure 1 - Figure 3, an electronic atomizer 100, the electronic atomizer 100 includes a housing 1 and an atomization component 3 disposed within the housing 1. An atomization channel 31 is provided within the atomization component 3; the electronic atomizer 100 further includes a mouthpiece 5, one end of the mouthpiece 5 extends into the housing 1 and communicates with the atomization channel 31. A mouthpiece hole 51 is formed on the mouthpiece 5. An absorption cotton 6 is disposed between the mouthpiece 5 and the atomization component 3. An absorption cotton perforation 61 is formed within the absorption cotton 6. The atomization channel 31, the absorption cotton perforation 61, and the mouthpiece hole 51 are sequentially communicated. An upper sealing member 4 is further disposed between the mouthpiece 5 and the atomization component 3. The upper sealing member 4 seals the gap between the absorption cotton 6 and the atomization component 3; a through hole 42 is formed on the upper sealing member 4 corresponding to the absorption cotton perforation 61. The inner diameter of the absorption cotton perforation 61 is greater than that of the through hole 42 in at least one direction. The inner walls of the through hole 42 and the absorption cotton perforation 61 are offset in this direction to form a step 41.

[0034] The step 41 is formed on the side of the upper sealing member 4 close to the absorption cotton 6, so that the upper sealing member 4 fits more closely with the absorption cotton perforation 61, reducing the risk of leakage of the atomized liquid or condensate from this interface. At the same time, the step 41 can be a micro liquid collection groove or diversion groove. When condensate seeps out inside the absorption cotton perforation 61, the step 41 effectively slows down the flow rate of the condensate here, helping the absorption cotton 6 to collect and guide the condensate, preventing it from flowing into the through hole 42 of the upper sealing member 4 through the absorption cotton perforation 61.

[0035] Specifically, the step 41 is a shallow recess or deep groove machined from the surface of the absorption cotton 6 in contact with the upper sealing member 4 towards the inside of the upper sealing member 4.

[0036] It can be understood that the inner diameter of the absorption cotton perforation 61 being greater than that of the through hole 42 in at least one direction can enable the absorption cotton 6 to exert a certain pressure on the upper sealing member 4, making the joint between the upper sealing member 4 and the absorption cotton 6 tighter, effectively filling the gap between the absorption cotton perforation 61 and the through hole 42, ensuring a good sealing effect, and reducing the possibility of smoke leakage.

[0037] The through hole 42 is provided for docking with the absorption cotton perforation 61. The atomized liquid vapor enters the absorption cotton perforation 61 through the through hole 42 and can be inhaled by the user into the mouthpiece hole 51.

[0038] Specifically, the upper sealing member 4 is made of silica gel material, and silica gel can provide reliable sealing and has good tolerance to many chemical substances.

[0039] Further, please refer to Figure 4 - Figure 5 , the lower part of the mouthpiece 5 has a cavity, defined as a receiving cavity 52. The receiving cavity 52 communicates with the mouthpiece hole 51, and the absorption cotton 6 is disposed within the receiving cavity 52.

[0040] AsFigure 2 The shown electronic atomizer 100 has a shape and size of the mouthpiece 5 exposed from the housing 1 that is adapted to the shape of a human mouth and is suitable for sucking; while the part extending into the interior of the housing 1 is adapted to the shape of the absorbent cotton 6 and can fully cooperate with the mist outlet channel 31 to receive the atomized liquid vapor rising during user sucking.

[0041] Specifically, the absorbent cotton 6 is made of a material with good oil absorption performance, such as non-woven fabric, organic cotton, glass fiber cotton or polymer adsorption material. It is arranged between the atomization component 3 and the mouthpiece 5, can completely cover the path of the atomized liquid vapor from the mist outlet channel 31 to the mouthpiece hole 51, and is provided with absorbent cotton perforations 61 inside, which are connected to the mist outlet channel 31 and the mouthpiece hole 51 in the atomization component 3. These perforations and channels are either small holes or micropores, which are sufficient to allow the atomized liquid vapor to pass through while maintaining good sealing performance.

[0042] Furthermore, the fixation of the absorbent cotton 6 is achieved by its own shape and thickness being fully adapted to the internal structure of the mouthpiece 5.

[0043] Furthermore, the absorbent cotton 6 includes a first absorbent cotton 62 and a second absorbent cotton 63. The first absorbent cotton 62 and the second absorbent cotton 63 are stacked, and the cross-sectional area of the second absorbent cotton 63 is larger than that of the first absorbent cotton 62 layer. Specifically, the first absorbent cotton 62 and the second absorbent cotton 63 are stacked vertically, with the second absorbent cotton 63 at the bottom and the first absorbent cotton 62 at the top. The difference in their cross-sectional areas increases the overall absorption capacity. The smaller first absorbent cotton 62 serves to initially absorb the liquid, and the second absorbent cotton 63 with a larger cross-sectional area can absorb more liquid. The liquid absorbed by the first absorbent cotton 62 can be gradually released to the second absorbent cotton 63, which helps to disperse the absorption load of the liquid and improve the overall absorption ability and efficiency.

[0044] Furthermore, a stop surface 53 is defined in the mouthpiece 5 near the mouthpiece hole 51 and facing the mist outlet channel 31, and a sealing gasket 2 is provided between the absorbent cotton 6 and the stop surface 53.

[0045] Specifically, the sealing gasket 2 is made of a soft, high-temperature resistant, and chemically corrosion-resistant material. Its shape and size match the contact surface between the stop surface 53 and the absorbent cotton 6, and usually match the mouthpiece hole 51 to ensure that it can completely cover the stop surface 53 after installation and form a good seal.

[0046] Furthermore, a sealing gasket opening 21 is provided on the sealing gasket 2 corresponding to the mouthpiece hole 51, and the sealing gasket opening 21 communicates the mouthpiece hole 51 with the absorbent cotton perforations 61.

[0047] Specifically, the position of the sealing gasket opening 21 corresponds to the position of the nozzle hole 51, is similar to the shape of the nozzle hole 51, and the size of the sealing gasket opening 21 is slightly larger than the diameters of the absorbent cotton perforation 61 and the nozzle hole 51, so as to establish an effective channel with the absorbent cotton perforation 61 and the nozzle hole 51, and the atomized liquid vapor can be smoothly inhaled into the nozzle hole 51.

[0048] Further, an oil cup bracket 7 is also arranged in the housing 1, and the oil cup bracket 7 is connected with the upper sealing member 4 in an interference fit manner.

[0049] Specifically, several connecting columns 44 are arranged on one side of the upper sealing member 4 facing the oil cup bracket 7, and connecting slots adapted to the connecting columns 44 are opened on the oil cup bracket 7. The upper sealing member 4 made of silica gel has good flexibility and elasticity. The diameter of the connecting column 44 is slightly larger than the diameter of the connecting slot and is in an interference fit with the connecting slot.

[0050] Specifically, the function of the oil cup bracket 7 is to support and fix the oil cup inside the electronic atomizer 100 to ensure that the oil cup is stably held in place during use.

[0051] Furthermore, the atomization assembly 3 further includes a heating wire 32 and a mist outlet pipe 33 connected to the heating wire 32. The heating wire 32 and the mist outlet pipe 33 are arranged in the mist outlet channel 31. The mist outlet channel 31 penetrates through the inside of the oil cup bracket 7 along the length direction of the electronic atomizer 100, and can fully and evenly heat the oil cup or the absorbent cotton in the oil cup bracket 7 to obtain a long and continuous atomized liquid vapor for the user to use.

[0052] Further, the housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 enclose a chamber for accommodating the internal components of the electronic atomizer 100, and the shape and size of the oil cup bracket 7 are adapted to the shape and size of the chamber.

[0053] Further, the electronic atomizer 100 further includes a lower sealing member 8. The lower sealing member 8 is snap-connected to the lower housing 12 to form an accommodating chamber, and the electronic components of the electronic atomizer 100 are hermetically protected in the accommodating chamber by the lower sealing member 8.

[0054] Further, an extension portion 43 is arranged on the upper sealing member 4 corresponding to the side of the nozzle 5 facing the oil cup bracket 7, and the extension portion 43 seals the gap between the nozzle 5 and the oil cup bracket 7.

[0055] Specifically, the extension portion 43, as a part of the sealing member, is a flat platform and forms a tight contact surface with the edge of the oil cup bracket 7.

[0056] Further, please refer to Figure 5, the extension part 43 is provided with a connecting wall 431 facing the inner wall of the suction nozzle 5, and a connecting groove 521 corresponding to the connecting wall 431 is arranged on the inner wall of the suction nozzle 5. The connecting wall 431 is hermetically connected to the connecting groove 521.

[0057] Furthermore, an oil cup bracket opening 71 corresponding to the through hole 42 is arranged on the oil cup bracket 7, and the oil cup bracket opening 71 communicates with the mist outlet passage 31.

[0058] Specifically, the oil cup bracket opening 71 directly communicates with the mist outlet passage 31, is arranged at the top of the oil cup bracket 7, and communicates with the suction nozzle hole 51.

[0059] Furthermore, please refer to Figure 5 , the present utility model further provides an implementable method with a smoke pipe 9 in the mist outlet passage 31, as Figure 5 shown, a part of the smoke pipe 9 extends into the absorption cotton perforation 61 and the through hole 42 of the upper sealing member 4 and communicates with the suction nozzle hole 51. In this embodiment, the step 41 formed by the offset of the through hole 42 of the upper sealing member 4 and the absorption cotton perforation 61 of the absorption cotton 6 due to the inner diameter difference in at least one direction increases the air pressure between the smoke pipe 9 and the absorption cotton perforation 61 during inhalation, hinders the flow of condensate into the smoke pipe 9 and the interior of the electronic atomizer 100, and helps the absorption cotton 6 better absorb the condensate.

[0060] Furthermore, a distance L (such as the L shown in Figure 5 ) is left between the upper end of the smoke pipe 9 and the top of the absorption cotton perforation 61, and a liquid storage tank 91 is formed between at least a part of the inner wall of the smoke pipe 9 and the absorption cotton perforation 61.

[0061] Specifically, the liquid storage tank 91 is formed by the inner diameter difference between the smoke pipe and the absorption cotton perforation, forming a small storage space in the absorption cotton perforation 61, preventing condensate from entering the user's mouth through the suction nozzle hole 51, and also helping to maintain the dryness and clarity of the atomized liquid vapor.

[0062] It can be understood that the distance L (such as the L shown in Figure 5 ) left between the upper end of the smoke pipe 9 and the top of the absorption cotton perforation 61 can prevent the condensate formed at the suction nozzle hole 51 from directly entering the smoke pipe 9, ensuring that the top of the smoke pipe 9 is always kept dry, thereby maintaining the purity and taste of the atomized liquid vapor.

[0063] Compared with the prior art, the electronic atomizer provided by the present utility model has the following advantages:

[0064] 1. In the electronic atomizer provided in the embodiment of the present utility model, the absorption cotton is arranged between the atomization component and the mouthpiece of the electronic atomizer. When the user inhales, the hot atomized liquid vapor will flow through the absorption cotton via the mist outlet channel. The hot atomized liquid vapor condenses into condensate at the mouthpiece, and the absorption cotton absorbs the condensate to prevent it from entering the user's mouth through the mouthpiece holes and also prevent the condensate from flowing into the interior of the atomization component. Absorption cotton perforations are provided inside the absorption cotton to connect the mist outlet channel, the absorption cotton, and the mouthpiece holes in sequence, enabling the smoke to pass through the absorption cotton smoothly. The step between the absorption cotton and the upper seal slows down the flow rate of the condensate in the absorption cotton perforations, does not hinder the flow of the atomized liquid vapor, and fully adsorbs the condensate so that the condensate is not easily refluxed; the inner diameter of the absorption cotton perforations is larger than that of the through holes in at least one direction, enabling the absorption cotton to exert a certain pressure on the upper seal and promoting a tighter engagement between the upper seal and the absorption cotton.

[0065] 2. In the electronic atomizer provided in the embodiment of the present utility model, the smoke tube keeps the atomized liquid vapor dry, ensuring that no extra impurities are inhaled when the atomized liquid vapor passes through the absorption cotton perforations, providing a better product experience for users; the relatively hot atomized liquid vapor turns into condensate when it reaches the mouthpiece holes, and the liquid storage tank can block the downward flow path of the condensate, promoting the absorption cotton to absorb the condensate more fully and preventing the condensate from entering the interior of the electronic atomizer and causing adverse effects.

[0066] 3. In the electronic atomizer provided in the embodiment of the present utility model, the first absorption cotton is responsible for first contacting and absorbing most of the condensate generated, and the second absorption cotton serves as a supplement to the first layer of absorption cotton. Its larger cross-sectional area means that the second absorption cotton can absorb more liquid. The layered arrangement can ensure that even under frequent use and high load conditions, the electronic atomizer can effectively absorb the condensate, extending the service life and maintenance cycle.

[0067] 4. In the electronic atomizer provided in the embodiment of the present utility model, the sealing gasket ensures the sealing between the mouthpiece and the mist outlet channel. During the use of the electronic atomizer, if the joint between the absorption cotton and the mouthpiece opening is not effectively sealed, it may cause the atomized liquid or condensate to leak out from the joint, affecting the user experience. The sealing gasket and the opening provided on the sealing gasket corresponding to the mouthpiece holes ensure the stability and integrity of the mist outlet channel, thus ensuring that the smoke can flow out from the mouthpiece holes along the well-designed path.

[0068] 5. In the electronic atomizer provided in the embodiment of the present utility model, the mouthpiece has a receiving cavity that can serve as a spare liquid collection chamber. The liquid collection chamber prevents the atomized liquid or condensate from leaking from the mouthpiece holes, and the absorption cotton in the receiving cavity effectively absorbs and stores the condensate, extending the service life of the electronic atomizer.

[0069] 6. In the electronic atomizer provided in the embodiment of the present utility model, the oil cup bracket is a container for accommodating the atomization liquid. The user can fill the pre-loaded atomization liquid into the oil cup bracket. The oil cup bracket can effectively isolate the atomization liquid from the main electronic components inside the electronic atomizer, and is detachably connected to the upper sealing member, so that the oil cup bracket can be conveniently taken out from the electronic atomizer.

[0070] 7. In the electronic atomizer provided in the embodiment of the present utility model, the extension portion provided on the side of the upper sealing member corresponding to the mouthpiece facing the atomization assembly can effectively seal the gap between the mouthpiece and the oil cup bracket, prevent leakage, protect the internal components. The sealed connection between the connecting wall and the connecting groove ensures the stable connection between the lower sealing member and the oil cup bracket. The interface between the connecting wall and the connecting groove is completely sealed, preventing the atomization liquid or condensate from leaking out from the joint between the inner wall of the mouthpiece and the lower sealing member, maintaining the stability of the smoke, and improving the overall quality of the product.

[0071] 8. In the electronic atomizer provided in the embodiment of the present utility model, the oil cup bracket has an opening communicating with the mist outlet channel to ensure the stable supply of the atomization liquid during the heating process, so that the electronic atomizer effectively conveys the vapor of the heated atomization liquid into the mouthpiece for the user to inhale.

[0072] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the principles of the present utility model shall be included within the protection scope of the present utility model.
