Description

Technical Field

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

[0002] It is well known that smoking is harmful to health, causing millions of deaths and triggering various diseases every year. Quitting smoking is a global trend, and governments around the world are actively advocating for it. However, getting smokers to quit is extremely difficult, and the number of smokers is increasing globally, with the age of first-time smokers getting younger and younger. Furthermore, with the increase in the number of smokers, the global demand for tobacco leaves is also increasing, requiring vast amounts of arable land to grow tobacco and meet the needs of cigarette factories. While the tobacco industry brings in huge tax revenues for governments, it poses a significant threat to public health, especially for non-smokers, as the harm caused by secondhand smoke is even greater.

[0003] To avoid the harms of smoking, researchers worldwide have developed e-cigarettes as an alternative to traditional cigarettes. Specifically, e-cigarettes work by using circuitry to instantly atomize e-liquid placed in a mouthpiece, producing an aerosol for the user to inhale. The e-liquid formula can be customized to the user's preferences and taste, thus addressing the needs of smokers. However, current e-cigarettes still suffer from complex structures and the inability to be reused after the e-liquid is depleted. This results in larger, less portable e-cigarettes that are less comfortable to hold, and also increases manufacturing costs. Utility Model Content

[0004] Based on this, the purpose of this application is to provide an electronic atomizing device to solve the problems of existing electronic cigarette products having complex structures and being unable to reuse e-liquid after it is exhausted, resulting in large size, affecting the feel and high manufacturing cost.

[0005] According to one aspect of this application, an electronic atomizing device is provided, comprising:

[0006] An atomizing rod, wherein an oil storage chamber and an air passage are connected inside the atomizing rod, and an atomizing core is provided in the oil storage chamber or the air passage;

[0007] A battery rod is electrically connected to the atomizing core and coaxially arranged with the atomizing rod. One end of the battery rod along its own axial direction has an air inlet, and the other end is detachably connected to the atomizing rod.

[0008] The nozzle is located at the end of the atomizing rod away from the battery rod and is partially inserted into the atomizing rod. The nozzle has an air outlet, and the air outlet and the air inlet are interconnected through the air passage.

[0009] The nozzle, the atomizing rod, and the battery rod are all cylindrical, and the portion of the nozzle exposed on the atomizing rod, the atomizing rod, and the battery rod all have the same outer diameter.

[0010] In one embodiment, the atomizing rod includes a first housing with openings at both ends along its own axial direction and an oil reservoir disposed within the first housing. The mouthpiece blocks one opening of the first housing, and the battery rod blocks the other opening of the first housing. The oil reservoir is provided with a first partition, and the oil reservoir and the air passage are separated by the first partition.

[0011] In one embodiment, the length of the first partition is less than the length of the oil storage component along the axial direction of the atomizing rod, such that one end of the first partition forms an atomizing cavity with the inner wall of the oil storage component, which communicates the oil storage cavity and the air passage, and the atomizing core is disposed at one end of the oil storage cavity near the atomizing cavity.

[0012] In one embodiment, the first partition has two pieces, which are arranged radially apart along the atomizing rod, such that the two first partitions divide the inner cavity of the oil storage member into one oil storage chamber and two air passages, which are arranged radially on both sides of the oil storage chamber.

[0013] In one embodiment, the oil storage chamber is provided with a second partition, the four edges of which are connected to the inner walls of the first partition and the oil storage component, so that the second partition divides the oil storage chamber into a first cavity and a second cavity; the second partition has oil inlet holes extending through opposite sides in its thickness direction, and the first cavity and the second cavity are interconnected through the oil inlet holes; the first cavity is used to store the atomizing medium, and the atomizing core is disposed in the second cavity.

[0014] In one embodiment, the battery rod includes:

[0015] The second housing has an opening at one end along its own axial direction, and the air inlet is located at the opposite end of the second housing;

[0016] The battery is disposed inside the second housing and electrically connected to the atomizing core;

[0017] A connecting component is partially inserted into and seals the opening of the second housing. The portion of the connecting component exposed outside the second housing is inserted into the opening of the first housing away from the nozzle. The portion of the connecting component exposed outside the second housing has a first slot. The oil reservoir or the end of the first housing away from the nozzle has a first buckle, which engages with the first slot. The connecting component also has vent holes penetrating its own axial direction at opposite ends. One end of the vent hole is connected to the air passage, and the other end is connected to the air inlet.

[0018] In one embodiment, the connecting component also has power-conducting holes extending through its axial direction to opposite ends. The battery rod also includes a pin, which passes through the power-conducting holes, with one end of the pin connected to the battery and the other end abutting against the atomizing core.

[0019] In one embodiment, the connecting component includes a first connector and a second connector. The second connector includes a body and a spring piece connected to the body. The spring piece is inserted into the first connector. The body is exposed outside the first connector. A first slot is formed on the side wall of the body. The spring piece has a second buckle. A second slot is formed on the inner wall of the first connector. The second buckle is engaged in the second slot.

[0020] In one embodiment, the oil reservoir is made of a transparent material, and the first housing has a viewing window.

[0021] In one embodiment, the outer peripheral surface of the atomizing rod and / or the battery rod is fitted with a silicone sleeve.

[0022] The aforementioned electronic atomizing device, on the one hand, features a detachable structure for the atomizing rod and battery rod, allowing for disassembly and reconnection. When the e-liquid in the atomizing rod is depleted, a new atomizing rod and battery rod can be replaced, enabling reuse of the electronic atomizing device and avoiding the need for complete disposal after e-liquid depletion, thus saving costs. On the other hand, by designing the atomizing rod, battery rod, and mouthpiece as cylindrical and coaxially connected, and ensuring that the portion of the mouthpiece exposed on the atomizing rod, as well as the outer diameter of the atomizing rod and battery rod, are all the same, the overall outer diameter of the electronic atomizing device is small (e.g., around 9mm), making it similar in size to a real cigarette. This results in a smaller overall size, making it easier to carry and improving the user's grip, thus better aligning with the smoking habits of typical smokers. Attached Figure Description

[0040] One embodiment of this application provides an electronic atomizing device for heating an atomizing medium stored inside the device to form an aerosol for a user to inhale.

[0041] The following description uses an electronic cigarette as an example of an electronic atomizing device and e-liquid as an atomizing medium to illustrate the structure of the electronic atomizing device in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomizing device of this application is not limited to an electronic cigarette, but can also be any other electronic atomizing device capable of atomizing a medium into an aerosol, which is not limited here.

[0042] See Figure 1 and Figure 3 , Figure 1 This paper shows a schematic diagram of the appearance of the electronic atomizing device 10 in one embodiment of the present application. Figure 2 A top view of the electronic atomizing device 10 is shown. Figure 3 An exploded view of an electronic atomizing device 10 is shown. An embodiment of this application provides an electronic atomizing device 10 including an atomizing rod 100, a battery rod 200, and a mouthpiece 300. The battery rod 200 is connected to one end of the atomizing rod 100, and the mouthpiece 300 is located at the end of the atomizing rod 100 away from the battery rod 200. The battery rod 200 provides electrical power to the atomizing rod 100, enabling the atomizing rod 100 to atomize the e-liquid stored within it into an aerosol, which the user inhales through the mouthpiece 300.

[0043] Specifically, in the embodiments of this application, such as Figure 4 As shown, the atomizing rod 100 has a connected oil storage chamber 101 and an air passage 102. An atomizing core 110 is housed in either the oil storage chamber 101 or the air passage 102. The battery rod 200 is electrically connected to the atomizing core 110, with an air inlet (not shown) at one end and a detachable connection to the atomizing rod 100 at the other end. A portion of the mouthpiece 300 is inserted into the end of the atomizing rod 100 away from the battery rod 200, and the mouthpiece 300 has an air outlet 301. The air outlet 301 and the air inlet are interconnected via the air passage 102. When the user inhales, the e-liquid in the oil storage chamber 101 enters the atomizing core 110. The atomizing core 110 heats up rapidly after being powered on, atomizing the e-liquid into an aerosol. The aerosol mixes with air entering from the air inlet and is discharged through the air passage 102 and the air outlet 301.

[0044] In a preferred embodiment, such as Figure 1 As shown, the mouthpiece 300, atomizing rod 100, and battery rod 200 are all cylindrical, such as cylindrical or polygonal cylindrical, and the portion of the mouthpiece 300 exposed above the atomizing rod 100, as well as the outer diameter of the atomizing rod 100 and the battery rod 200, are all the same. Preferably, this outer diameter is 8mm-10mm, making the overall shape and size of the electronic atomizing device 10 close to that of a real cigarette. Therefore, the overall size of the electronic atomizing device 10 is small, making it easy to carry and improving the user's grip on the electronic atomizing device 10, which is more in line with the smoking habits of general smokers.

[0045] The following sections describe the specific structures of the atomizing rod 100 and the battery rod 200, respectively. Figure 3 and Figure 4 In the illustrated embodiment, the atomizing rod 100 includes a first housing 120 with openings at both opposite ends along its axial direction and an oil reservoir 130 disposed within the first housing 120. The first housing 120 has a cylindrical structure. The nozzle 300 blocks one end opening of the first housing 120, and one end of the battery rod 200 is inserted into the other end opening of the first housing 120 and blocks that opening. Figure 5 As shown, a first partition 140 is integrally connected inside the oil storage component 130. The oil storage chamber 101 and the air passage 102 are separated by the first partition 140. An oil storage cotton 150 is provided in the oil storage chamber 101. The oil storage cotton 150 has the functions of locking oil and guiding oil to prevent the e-liquid from flowing randomly.

[0046] Optionally, in the axial direction of the atomizing rod 100, the length of the first partition 140 is less than the length of the oil storage component 130, so that one end of the first partition 140 and the inner wall of the oil storage component 130 form an atomizing chamber 103 that connects the oil storage chamber 101 and the air passage 102; the atomizing core 110 is disposed at one end of the oil storage chamber 101 near the atomizing chamber 103.

[0047] In this way, the e-liquid in the oil storage chamber 101 can flow vertically downward along the axis of the atomizing rod 100 to the atomizing core 110. Then, the atomizing core 110 heats the e-liquid to generate an aerosol. The aerosol gathers in the atomizing chamber 103, mixes with the outside air, and then flows upward in a straight line through the air passage 102 to the air outlet 301 and is inhaled by the user, thus ensuring sufficient oil supply and smoother vaping.

[0048] In another embodiment, a through hole may be provided in the first partition 140 to allow the oil storage chamber 101 and the air passage 102 to communicate with each other through the through hole, without any particular limitation.

[0049] Furthermore, to increase the aerosol output, the first partition 140 has two parts, which are arranged radially apart along the atomizing rod 100. This allows the two partitions to divide the inner cavity of the oil storage component 130 into an oil storage chamber 101 and two air passages 102. The two air passages 102 are radially positioned on both sides of the oil storage chamber 101. In this way, the aerosol accumulated in the atomizing chamber 103 can flow from the two air passages 102 to the outlet 301 and converge, allowing the user to inhale more aerosol per unit time, thus improving the user's inhalation experience.

[0050] Of course, the internal structure of the atomizing rod 100 is not limited to the structure described in the above embodiment. A vent pipe can also be provided in the oil storage component 130. The outer wall of the vent pipe and the inner wall of the oil storage component 130 form an oil storage cavity 101. An air passage 102 is opened in the vent pipe. An opening in the side wall of the vent pipe connects the oil storage cavity 101 and the air passage 102. The atomizing core 110 is arranged in the vent pipe.

[0051] However, it is obvious that in the embodiment shown in the figure, the structure of the atomizing rod 100 is simpler and has fewer parts, which is beneficial to reducing the outer diameter of the electronic atomizing device 10.

[0052] Better, such as Figure 6As shown, a second partition 160 is also provided inside the oil storage chamber 101. The four edges of the second partition 160 are integrally connected to the inner walls of the first partition 140 and the oil storage component 130, so that the second partition 160 divides the oil storage chamber 101 into a first chamber 101a and a second chamber 101b. The second partition 160 has oil inlet holes 161 extending through both sides of its thickness direction. The first chamber 101a and the second chamber 101b are interconnected through the oil inlet holes 161. E-liquid is stored in the first chamber 101a, and the atomizing core 110 is located in the second chamber 101b. By setting the second partition 160, the e-liquid in the first chamber 101a can be blocked to a certain extent, preventing the e-liquid in the first chamber 101a from flowing downward too quickly and causing leakage. More preferably, the volume of the second cavity 101b is close to the volume of the atomizing core 110, and slightly larger than the atomizing core 110, so that the atomizing core 110 has its own installation space. The atomizing core 110 is embedded in the second cavity 101b, and the atomizing core 110 can be easily fixed without the need for other parts.

[0053] Optionally, the oil reservoir 130 is made of a transparent material, such as... Figure 1 As shown, the first housing 120 has a viewing window 121, allowing the user to see the amount of e-liquid remaining in the oil storage chamber 101. Of course, the first housing 120 and the oil storage component 130 can be an integrally connected part, and the entire part can be made of transparent material; there is no limitation on this.

[0054] Please continue reading. Figure 2 and Figure 3 In the structure of the battery rod 200, the battery rod 200 includes a second housing 210, a battery 220, and a connecting assembly 230. The second housing 210 is also cylindrical, with an opening at one end along its own axial direction, and an air inlet at the opposite end of the second housing 210. The battery 220 is disposed inside the second housing 210 and electrically connected to the atomizing core 110. The connecting assembly 230 is partially inserted into the opening of the second housing 210 and seals the opening, while the portion of the connecting assembly 230 exposed outside the second housing 210 is inserted into the opening at the end of the first housing 120 away from the mouthpiece 300, and simultaneously combined with... Figure 7 and Figure 8 As shown, the portion of the connecting component 230 exposed outside the first housing 120 has a first slot 231, and the end of the oil reservoir 130 or the first housing 120 away from the nozzle 300 has a first buckle 131, which engages with the first slot 231. In the embodiment shown, the first buckle 131 is located on the edge of the end of the oil reservoir 130 away from the nozzle 300.

[0055] As can be seen, by setting the first buckle 131 to engage with the first slot 231, not only can the atomizing rod 100 and the battery rod 200 be securely connected, preventing the battery rod 200 from falling off during use due to its weight exceeding that of the atomizing rod 100, but it also facilitates the disassembly and reassembly of the atomizing rod 100 and the battery rod 200. When the e-liquid in the atomizing rod 100 is exhausted, a new atomizing rod 100 and battery rod 200 can be replaced and reconnected, thus allowing the electronic atomizing device 10 to be reused and avoiding the need to discard the entire electronic atomizing device 10 after the e-liquid is exhausted, thereby saving costs; or, when the electronic atomizing device 10 is not used for a long time, the atomizing rod 100 and battery rod 200 can be stored separately to prevent children from accidentally inhaling the electronic atomizing device 10 while playing. When the atomizer 100 and battery rod 200 are placed separately, a sealing cap can be fitted onto the end of the atomizer 100 away from the mouthpiece 300 to prevent e-liquid leakage. It is understood that the atomizer 100 and battery rod 200 can be detachably connected not only by snapping into a slot, but also by magnetic attraction; this is not limited here.

[0056] Please refer to the following: Figure 6 In one embodiment, the connecting component 230 is further provided with a vent 232 extending through both ends of itself. One end of the vent 232 is connected to the air passage 102, and the other end is connected to the air inlet. Figure 6 In the embodiment, there are two vent holes 232. The two vent holes 232 are symmetrically arranged radially along the connecting component 230 with the central axis of the connecting component 230 as the axis of symmetry. Of course, there is no limit to the number of vent holes 232. After the outside air enters the battery rod 200 through the air inlet, it can enter the atomizing chamber 103 through the vent holes 232 and merge with the aerosol.

[0057] As an optional implementation, such as Figure 8 As shown, the atomizing core 110 is connected to the battery 220 via two pins 240, one of which serves as the positive terminal and the other as the negative terminal. The two pins 240 pass through the connecting assembly 230. Specifically, the connecting assembly 230 has two power-conducting holes 233 that pass through its axial direction at opposite ends. The two power-conducting holes 233 are also symmetrically arranged radially along the connecting assembly 230 with the central axis of the connecting assembly 230 as the axis of symmetry. All power-conducting holes 233 and all ventilation holes 232 are staggered along the circumference of the connecting assembly 230. Each pin 240 passes through a corresponding power-conducting hole 233, so that one end of each pin 240 is connected to the battery 220, and the other end can pass through the connecting assembly 230 and abut against the atomizing core 110. This not only achieves electrical connection between the atomizing core 110 and the battery 220, but also prevents e-liquid or condensate in the atomizing rod 100 from dripping down into the battery rod 200 to a certain extent.

[0058] Preferably, the power-conducting hole 233 is provided with an elastic element made of, for example, silicone material. The elastic element has through holes extending through both ends of itself. The through holes are formed by the ejector pin 240 piercing the elastic element. The ejector pin 240 passes through both the power-conducting hole 233 and the through holes. In this way, by utilizing the recoverable deformation of the elastic element, the elastic element can wrap around the ejector pin 240, thereby serving to fix and seal the ejector pin 240.

[0059] Specifically, this relates to the structure of the connecting component 230, such as... Figure 6 , Figure 8 and Figure 9 As shown, the connecting component 230 includes a first connector 234 and a second connector 235. The first connector 234 is a hollow cylindrical structure. The second connector 235 includes a body 2351 and a spring piece 2352 connected to the body 2351. The spring piece 2352 is inserted into the first connector 234, and the body 2351 is exposed outside the first connector 234. A first slot 231 is formed on the side wall of the body 2351. The spring piece 2352 has a second buckle 2353. A second slot 2341 is formed on the inner wall of the first connector 234. The second buckle 2353 is engaged in the second slot 2341, so that the first connector 234 and the second connector 235 can be easily assembled and can also be firmly connected to prevent them from falling off each other.

[0060] In addition, as a preferred embodiment, such as Figure 1 As shown, a silicone sleeve 400 is fitted on the outer peripheral surface of the atomizing rod 100 and / or the battery rod 200. The silicone sleeve 400 can be fitted only on the outer peripheral surface of the atomizing rod 100, or only on the outer peripheral surface of the battery rod 200, or simultaneously on both the atomizing rod 100 and the battery rod 200, for example, at the connection position between the atomizing rod 100 and the battery rod 200. This can prevent the electronic atomizing device 10 from slipping out of the hand and further improve the grip.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
