Description

Technical Field

[0001] This utility model belongs to the field of atomization technology, and in particular relates to an atomizer and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices have gained attention due to their portability and ease of use. These devices use electrical heating to atomize the atomizing medium into an aerosol. Liquid-heated electronic atomizing devices typically include an atomizer and a reservoir. The reservoir holds the atomizing liquid and supplies it to the atomizer, while the atomizer includes a liquid guide for conducting the liquid and a heating element for heating and atomizing the liquid. In related technologies, atomizers often use a side-entry method with a single-piece cotton coil. However, due to factors such as the thickness and density of the cotton, this method can lead to either slow coil filling resulting in burnt coils or excessively fast filling causing leakage, failing to meet user needs. Utility Model Content

[0003] The technical objective of this utility model is to provide an atomizer and an electronic atomizing device, aiming to solve the problem of difficulty in controlling the oil inlet speed of electronic atomizing devices in related technologies.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: Firstly, it provides an atomizer, which includes: a housing and a base connected to one end of the housing, and a cover, a first liquid-guiding cotton, an atomizing tube, and an atomizing core arranged sequentially from the outside to the inside within the housing; a first liquid storage cavity is formed by the housing, the base, and the cover; the cover has a first liquid-guiding port and a vent hole that are spaced apart from each other and communicate with the first liquid storage cavity; the atomizing tube has a second liquid-guiding port that communicates with the first liquid-guiding cotton and the atomizing core; the position of the first liquid-guiding port in the height direction is lower than that of the first liquid-guiding cotton, and the vent hole corresponds to the heating area of ​​the atomizing core.

[0005] Furthermore, an inlet gap is formed between the first liquid-guiding cotton and the base, which connects to the first liquid-guiding port.

[0006] Furthermore, the first liquid guiding cotton includes a first liquid guiding cotton and a second liquid guiding cotton arranged axially between the atomizing tube and the cover, and the liquid inlet gap is formed between the second liquid guiding cotton and the base.

[0007] Furthermore, the density of the first liquid-guiding cotton is greater than the density of the second liquid-guiding cotton.

[0008] Furthermore, the diameter of the ventilation hole is 0.6–1.0 mm.

[0009] Furthermore, the guide surface in the base used to enclose and form the first liquid storage cavity gradually slopes downward from the side near the shell to the side near the cover, and the lowest point of the guide surface is at the same height as the first liquid inlet.

[0010] Furthermore, multiple first liquid inlets are arranged at intervals.

[0011] In a second aspect, an electronic atomizing device is provided, including a power supply device and an atomizer as described in the first aspect, wherein the atomizer is electrically connected to the power supply device.

[0012] Thirdly, an electronic atomizing device is provided, including a liquid storage assembly and an atomizer as described in the first aspect, wherein the atomizer is detachably connected to the liquid storage assembly, and the liquid storage assembly has a second liquid storage chamber communicating with a first liquid storage chamber.

[0013] Furthermore, the liquid storage assembly is provided with a plug-in cavity that is adapted to the shape of the atomizer housing, and the plug-in cavity is used to plug into and cooperate with the top of the housing; between the liquid storage assembly and the housing, one is provided with a fastening part, and the other is provided with a fastening groove corresponding to the fastening part. When the liquid storage assembly and the housing are plugged into place, the fastening part is embedded in the fastening groove.

[0014] Furthermore, the liquid storage assembly includes an oil cup and a sealing assembly fixed to the bottom side of the oil cup. The sealing assembly has a liquid guiding channel communicating with the insertion cavity. The top of the housing has an insertion part with a through liquid passage formed in the insertion part, which communicates with the first liquid storage cavity of the atomizer. The position and shape of the insertion part are adapted to the liquid guiding channel. When the liquid storage assembly is inserted into the housing, the outer side of the insertion part abuts against the wall of the liquid guiding channel.

[0015] Furthermore, a first limiting groove is provided on the outer periphery of the insertion part, and a sealing ring is fitted on the first limiting groove. The sealing ring is used to seal the gap between the insertion part and the liquid guiding channel when the insertion part is inserted and engaged with the liquid guiding channel.

[0016] Compared with existing technologies, the atomizer and electronic atomizing device of this utility model have the following advantages: Through the cooperation between the shell, the cover, and the first liquid-guiding cotton, oil can be introduced from the bottom of the first liquid-guiding cotton, allowing the first liquid-guiding cotton to quickly absorb e-liquid, thereby avoiding slow oil intake that could cause the coil to burn. When the atomizing coil is working, the amount of oil in the area of ​​the first liquid-guiding cotton that is at the same level as the heating area of ​​the atomizing coil will decrease rapidly, causing the first liquid-guiding cotton to breathe. This allows for air exchange through the ventilation holes of the cover. At the same time, the first liquid-guiding cotton is quickly replenished with oil, and once the cotton is saturated, air sealing is achieved. This achieves a balance between oil retention and preventing coil burning, improving the atomization effect and the user's vaping experience. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Example:

[0029] like Figure 1-5 As shown, in this embodiment, the atomizer 1 includes: a housing 11 and a base 12 connected to one end of the housing 11, and a cover 13, a first liquid-guiding cotton 14, an atomizing tube 15, and an atomizing core 16 arranged sequentially from the outside to the inside within the housing 11; a first liquid storage cavity 17 is formed between the housing 11, the base 12, and the cover 13; the cover 13 is provided with a first liquid-guiding port 131 and a ventilation hole 132 that are spaced apart from each other and connected to the first liquid storage cavity 17; the atomizing tube 15 is provided with a second liquid-guiding port 151 that connects the first liquid-guiding cotton 14 and the atomizing core 16; the position of the first liquid-guiding port 131 in the height direction is lower than that of the first liquid-guiding cotton 14, and the ventilation hole 132 corresponds to the heating area of ​​the atomizing core 16.

[0030] Specifically, through the cooperation between the shell 11, the cover 13, and the first liquid-guiding cotton 14, oil can be introduced from the bottom of the first liquid-guiding cotton 14, allowing it to quickly absorb e-liquid and thus preventing slow oil intake that could cause the coil to burn. The ventilation hole 132 corresponds to the heating area of ​​the atomizing coil 16, meaning that the ventilation hole 132 and the heating area of ​​the atomizing coil 16 can be located at the same height. The heating area can refer to the area corresponding to the heating part of the atomizing coil 16. When the atomizing coil 16 is working, the amount of oil in the area of ​​the first liquid-guiding cotton 14 that is at the same level as the heating area of ​​the atomizing coil 16 will decrease rapidly, causing the first liquid-guiding cotton 14 to breathe. This allows air to be exchanged through the ventilation hole 132 of the cover 13. At the same time, the first liquid-guiding cotton 14 is quickly replenished with oil, and once the cotton is saturated, air can be sealed. This achieves a balance between oil retention and preventing the coil from burning, improving the atomization effect and the user's vaping experience.

[0031] In this embodiment, an inlet gap 18 is formed between the first liquid-guiding cotton 14 and the base 12, communicating with the first liquid-guiding port 131. The presence of the inlet gap 18 helps to improve the liquid-guiding efficiency of the first liquid-guiding cotton 14. Further, in this embodiment, the guide surface 121 in the base 12 used to enclose and form the first liquid storage cavity 17 gradually slopes downward from the side near the housing 11 to the side near the cover 13, and the lowest point of the guide surface 121 is at the same height as the first liquid-guiding port 131. This design of the inclined guide surface 121 in this embodiment allows the atomized liquid to be guided more smoothly to the first liquid-guiding port 131 after entering the first liquid storage cavity 17, thereby improving the oil dispensing efficiency.

[0032] In this embodiment, the atomizing core 16 includes a heating wire 161 and a second liquid-guiding cotton 162 sandwiched between the heating wire 161 and the atomizing tube 15. An atomizing chamber 163 communicating with the atmosphere is formed on the inner side of the heating wire 161. After the atomized liquid reaches the first liquid-guiding cotton 14, it can continue to reach the heating wire 161 along the second liquid-guiding cotton 162. When the heating wire 161 is energized and heated, it can atomize the atomized liquid to form an aerosol. After the generated aerosol mixes with the atmosphere, it can be output along the atomizing chamber 163 to the outside of the electronic atomizing device for the user to inhale and experience.

[0033] In this embodiment, the first liquid-guiding cotton 14 includes a first liquid-guiding cotton 141 and a second liquid-guiding cotton 142 arranged axially between the atomizing tube 15 and the cover 13. An inlet gap 18 is formed between the second liquid-guiding cotton 142 and the base 12. Specifically, in this embodiment, the position of the second liquid-guiding cotton 142 can be lower than the position of the heating wire 161, and the first liquid-guiding cotton 141 can be at the same height as the heating wire 161. During the operation of the atomizer 1, the atomized liquid can sequentially reach the second liquid-guiding cotton 142, the first liquid-guiding cotton 141, the second liquid-guiding cotton 162, and the heating wire 161 through the inlet gap 18, achieving rapid liquid intake.

[0034] In this embodiment, the density of the first liquid-guiding cotton 141 is greater than the density of the second liquid-guiding cotton 142. Using the low-density second liquid-guiding cotton 142 enables rapid liquid ducting, while using the high-density first liquid-guiding cotton 141 enables efficient oil storage.

[0035] In this embodiment, the diameter of the vent 132 can be 0.6–1.0 mm. For example, the diameter of the vent 132 can be 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc., and is not limited thereto. Preferably, the diameter of the vent 132 can be 0.8 mm. In this embodiment, multiple first liquid guide ports 131 are arranged at intervals. That is, multiple spaced and evenly distributed first liquid guide ports 131 can be provided at the lower end of the cover 13, which is beneficial to improving liquid inlet efficiency and liquid inlet uniformity.

[0036] In this embodiment, the electronic atomizing device includes a liquid storage component 2 and an atomizer 1. The atomizer 1 is detachably connected to the liquid storage component 2. The liquid storage component 2 has a second liquid storage chamber 211 that communicates with the first liquid storage chamber 17. The liquid storage component 2 can be used to contain atomizing liquid and to provide atomizing liquid to the atomizer 1. The atomizer 1 can heat the atomizing liquid to turn it into an aerosol.

[0037] In this embodiment, the liquid storage assembly 2 is provided with a plug-in cavity 2221 that matches the shape of the housing 11 of the atomizer 1. The plug-in cavity 2221 is used for plugging into the top of the housing 11. Between the liquid storage assembly 2 and the housing 11, one is provided with a fastening part 113, and the other is provided with a fastening groove 2223 corresponding to the fastening part 113. When the liquid storage assembly 2 is plugged into the housing 11, the fastening part 113 is embedded in the fastening groove 2223. The liquid storage assembly 2 and the atomizer 1 are assembled by plugging and snapping, which is simple to operate and has good connection stability. By making the atomizer 1 and the liquid storage assembly 2 separate structures, the atomizer 1 can be reused repeatedly, which can avoid resource waste. In some specific embodiments, multiple fastening parts 113 can be provided at intervals on the periphery of the top of the outer shell, and fastening grooves 2223 corresponding to each fastening part 113 can be opened on the wall of the insertion cavity 2221. Through the cooperation between the fastening part 113 and the corresponding fastening groove 2223, a stable connection between the liquid storage component 2 and the atomizer 1 can be achieved.

[0038] In this embodiment, the liquid storage assembly 2 includes an oil cup 21 and a sealing assembly 22. The oil cup 21 has a spaced-apart second oil storage chamber 211 and an installation chamber. An inlet 212 is provided between the installation chamber and the second oil storage chamber 211. The sealing assembly 22 is rotatably fitted into the installation chamber. The sealing assembly 22 has a liquid guiding channel 223. The sealing assembly 22 is used to rotate relative to the oil cup 21, so that the liquid guiding channel 223 is misaligned with the inlet 212 to block the inlet 212, or to make the liquid guiding channel 223 connected to the inlet 212, thereby realizing the connection between the second oil storage chamber 211, the inlet 212, and the liquid guiding channel 223. In this embodiment, a rotating sealing assembly 22 is set in the oil storage assembly to realize the opening and closing control of the inlet 212, eliminating the need to design a special silicone plug part to block the oil passage before the electronic atomization device is activated. That is, the sealing component 22 integrates sealing and liquid guiding functions. When the electronic atomizing device is needed, rotating the sealing component 22 can achieve the connection between the liquid inlet 212 and the liquid guiding channel 223, so that the atomized liquid in the second liquid storage chamber 211 can be transported to the atomizer 1 of the electronic atomizing device for heating and atomization through the liquid guiding channel 223. When the electronic atomizing device is not needed, rotating the sealing component 22 can achieve the liquid path blockage, thereby effectively avoiding the occurrence of oil accumulation, clogging, oil leakage and other phenomena.

[0039] In this embodiment, the liquid storage assembly 2 includes an oil cup 21 and a sealing assembly 22 fixed to the bottom side of the oil cup 21. The sealing assembly 22 is provided with a liquid guiding channel 223 communicating with the insertion cavity 2221. The top of the housing 11 is provided with an insertion part 111. A through liquid passage hole 112 is formed in the insertion part 111, and the liquid passage hole 112 communicates with the first liquid storage cavity 17 of the atomizer 1. The position and shape of the insertion part 111 are adapted to the liquid guiding channel 223. When the liquid storage assembly 2 is inserted into the housing 11, the outer side of the insertion part 111 abuts against the wall of the liquid guiding channel 223.

[0040] Specifically, an air passage 213 is formed inside the oil cup 21, spaced apart from the second liquid storage chamber 211. The sealing assembly 22 includes a sealing element 221 and a support element 222. The bottom side of the sealing element 221 is provided with a positioning groove. The support element 222 is at least partially embedded in the positioning groove. The sealing element 221 is provided with a liquid guiding groove. The support element 222 is provided with a relief opening corresponding to the liquid guiding groove. The liquid guiding groove and the relief opening together form a liquid guiding channel 223. The insertion cavity 2221 is located on the side of the support element 222 away from the sealing element 221. The insertion part 111 of the housing 11 is used to abut against the relief opening when the liquid storage assembly 2 is inserted into the housing 11, so that after the liquid guiding channel 223 is connected to the liquid inlet 212, the atomizing liquid can enter the first liquid storage chamber 17 along the liquid guiding channel 223 and the liquid passage 112, thereby achieving efficient oil discharge. The top side of the support member 222 is also connected to a support portion, and the sealing member 221 has a clearance port that connects to the air passage 213. A through air chamber 2222 is formed inside the support portion, and the support portion is embedded in the clearance port. A flange is provided at the clearance port, and the flange abuts against the top of the support portion. When the liquid reservoir is connected to the atomizer 1, the atomizing chamber 163 in the atomizer 1 is connected to the air passage 2222. The aerosol generated by the atomizer 1 can be output to the outside of the electronic atomizing device along the atomizing chamber 163, the air passage 2222, the clearance port, and the air passage 213 for the user to enjoy the inhalation experience.

[0041] In this embodiment, a first limiting groove is provided on the outer periphery of the insertion part 111, and a sealing ring 114 is sleeved on the first limiting groove. The sealing ring 114 is used to seal the gap between the insertion part 111 and the liquid guiding channel 223 when the insertion part 111 is inserted and engaged with the liquid guiding channel 223, which helps to improve the connection stability and sealing stability between the insertion part 111 and the support member 222. In this embodiment, when the electronic atomizing device needs to be activated, the atomizer 1 can be rotated. The housing 11 of the atomizer 1 drives the support member 222 and the sealing member 221 to rotate. When the rotation is in place, the second liquid storage chamber 211, the liquid inlet 212, the liquid guiding channel 223, the liquid passage hole 112, the first liquid storage chamber 17, the second liquid guiding port 151, and the liquid inlet gap 18 can be connected to achieve rapid oil dispensing. Correspondingly, when the electronic atomizing device is not needed, rotating the atomizer 1 causes the housing 11 of the atomizer 1 to rotate the support 222 and the sealing 221. When the rotation is in place, the liquid inlet 212 and the liquid guiding channel 223 can be blocked, effectively preventing oil leakage.

[0042] In this embodiment, the electronic atomizing device also includes a power supply device, which is electrically connected to the atomizer 1. The power supply device can provide electrical energy to the atomizer 1. After the atomizer 1 is powered on, it can heat the atomizing liquid to atomize it and form an aerosol.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
