Description

Technical Field

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

[0002] In the prior art, to increase the atomization volume or e-liquid storage capacity of the atomizer, two oil tanks for storing e-liquid are configured for the atomizer. One oil tank serves as the working tank, and the other serves as the replenishment tank. The working tank is directly connected to the atomization chamber, and the replenishment tank is connected to the working tank. It is worth noting that as the e-liquid is consumed, the air pressure in the refill chamber gradually decreases. Since the working chamber is connected to the outside atmosphere via the atomization chamber, when the atomizer is in an upright position, the refill chamber is above the working chamber. As the e-liquid in the refill chamber decreases, the negative pressure in the refill chamber increases. This increases the resistance to the e-liquid flowing into the working chamber under gravity, potentially causing e-liquid backflow in the working chamber. Without replenishment, this results in a gurgling noise when the atomizer is inhaled. Furthermore, when the atomizer is not in an upright position, such as when it is laid flat, upside down, or tilted, the flow channel between the refill chamber and the working chamber cannot be completely filled with e-liquid. Outside air enters the refill chamber under negative pressure, balancing the air pressure between the working chamber and the refill chamber. The refill chamber cannot prevent e-liquid from flowing into the working chamber through negative pressure, while e-liquid continuously flows into the atomization chamber from the working chamber, ultimately leading to e-liquid leakage. To prevent the backflow of e-liquid caused by negative pressure in the refill chamber, existing technologies add an e-liquid reservoir to the working chamber. This reservoir absorbs the e-liquid through capillary action, thus preventing backflow. However, this reservoir increases costs and requires additional atomizer assembly steps. Utility Model Content

[0003] The main purpose of this invention is to propose an electronic atomizer to solve the problem in the prior art where negative pressure in the supply chamber forces the e-liquid in the working chamber to flow back.

[0004] To achieve the above objectives, this application provides an electronic atomizer, including an atomizing component and a refill chamber and a working chamber arranged from top to bottom, wherein...

[0005] The refill compartment has a first oil reservoir for storing e-liquid in the electronic atomizer.

[0006] The working chamber has a second oil storage chamber for storing e-liquid in the electronic atomizer. The second oil storage chamber is in fluid communication with the first oil storage chamber, and the volume of the second oil storage chamber is smaller than the volume of the first oil storage chamber.

[0007] An atomizing assembly includes an atomizing tube and an atomizing core assembled inside the atomizing tube. The atomizing tube is assembled inside the working chamber. A second oil inlet is provided on the tube wall of the atomizing tube, and a second oil storage chamber is formed between the outer wall of the atomizing tube and the inner wall of the working chamber. The second oil inlet communicates with the second oil storage chamber.

[0008] The inner wall of the working chamber is provided with a plurality of ribs that are distributed circumferentially and are far away from the communication between the first oil storage chamber and the second oil storage chamber. Adjacent ribs are spaced apart to form capillary gaps.

[0009] In some embodiments, the spacing between adjacent ribs is 0.1-1 mm.

[0010] In some embodiments, the ribs are arranged radially opposite to the atomizing tube.

[0011] In some embodiments, the radial distance between the ribs and the outer wall of the atomizing tube is greater than or equal to 0.1 mm.

[0012] In some embodiments, the volume of the first oil storage chamber is V1, and the volume of the second oil storage chamber is V2, wherein V1 / 5 ≤ V2 < V1.

[0013] In some embodiments, an oil guide is provided between the first oil storage chamber and the second oil storage chamber. A portion of the oil guide extends into the first oil storage chamber and the other portion extends into the second oil storage chamber, for guiding the e-liquid from the first oil storage chamber to the second oil storage chamber.

[0014] In some embodiments, the supply chamber and the working chamber are detachably connected. The supply chamber is provided with an oil outlet, and a sealing plug is removably provided at the oil outlet. The working chamber is provided with a first oil inlet that coincides with the oil outlet on the same axis. One end of the oil guide is fixed in the second oil storage chamber, and the other end of the oil guide extends out of the first oil inlet and extends along the axis toward the oil outlet. When the supply chamber and the working chamber are connected, the oil guide removes the sealing plug from the oil outlet and partially extends into the first oil storage chamber, so that the first oil inlet and the oil outlet are in communication.

[0015] In some embodiments, the oil guide is provided with a guide groove, which can penetrate the oil guide or run along the surface of the oil guide and connect to the second oil storage chamber. The guide groove guides the e-liquid in the first oil storage chamber to flow to the second oil storage chamber.

[0016] In some embodiments, an oil passage gap is provided between the oil guide and the first oil inlet.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects: as the negative pressure in the first oil storage chamber increases as the e-liquid decreases, the capillary gaps formed between the ribs in the second oil storage chamber can absorb the e-liquid, and the resistance to the e-liquid being drawn out by the negative pressure in the first oil storage chamber increases; in addition, it reduces the usage cost and assembly cost of the oil storage component.

[0030] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] refer to Figures 1 to 7 As shown, this application provides an electronic atomizer 1, which includes an atomizing component and a refill chamber and a working chamber 20 arranged from top to bottom. The refill chamber has a first oil reservoir 11 inside; the working chamber 20 has a second oil reservoir 200 with a volume smaller than the first oil reservoir 11, and the second oil reservoir 200 is in fluid communication with the first oil reservoir 11. The inner wall of the working chamber 20 has a plurality of protruding, circumferentially distributed, and spaced away from the first oil reservoir 11 and the second oil reservoir 200. The ribs 210 at the 00 connection point have a spacing of 0.2-0.6 mm between adjacent ribs 210; the atomizing assembly includes an atomizing tube 30 and an atomizing core 40 assembled in the atomizing tube 30. The atomizing tube 30 is at least partially assembled in the working chamber 20. The tube wall of the atomizing tube 30 is provided with a second oil inlet 31, and the outer wall of the atomizing tube 30 and the inner wall of the working chamber 20 define a second oil storage chamber 200. The second oil inlet 31 communicates with the second oil storage chamber 200.

[0033] refer to Figures 2 to 5 As shown, the electronic atomizer 1 has a supply chamber constituting its upper structure and a working chamber 20 constituting its lower structure.

[0034] The refueling compartment includes a first compartment body 10 constituting the upper structure and a sealing seat 12. The first compartment body 10 has an opening on one side, and the sealing seat 12 is installed inside the first compartment body 10 from the opening. The sealing seat 12 is interference-fitted with the first compartment body 10. The top surface of the sealing seat 12 and part of the inner wall of the first compartment body 10 form a first oil storage cavity 11. The sealing seat 12 is provided with an oil outlet 120, through which the e-liquid can flow to the second oil storage cavity 200.

[0035] For example, a sealing plug 121 is inserted at the oil outlet 120, and the sealing plug 121 can be driven out of the oil outlet 120 by external force.

[0036] The refill compartment can also be used as the mouthpiece for inhaling aerosols in an electronic atomizer. For example... Figure 5 As shown, a mouth is formed on the outer side of the first chamber 10, which communicates with the outside atmosphere. The first chamber 10 extends inward from the mouth to form a vent pipe. The sealing seat 12 is provided with an insertion interface that communicates with the outside atmosphere. When the sealing seat 12 closes the first chamber 10, the vent pipe is inserted into the insertion interface. The top surface of the sealing seat 12, the outer wall of the vent pipe, and part of the inner wall of the chamber form the first oil storage chamber 11 mentioned above. An air passage 100 for aerosol to pass through is formed inside the vent pipe.

[0037] In some embodiments, the supply compartment and the working compartment 20 are snapped together, with one of the two compartments having a receiving cavity 13 for receiving the other. For example, as shown... Figure 5 As shown, the lower part of the first chamber 10 has an opening, and a sealing seat 12 is installed inside the first chamber 10 from the opening. The top surface of the sealing seat 12 and part of the inner wall of the first chamber 10 form a first oil storage cavity 11, and the bottom surface of the sealing seat 12 and part of the inner wall of the first chamber 10 form an open receiving cavity 13. Exemplarily, the aforementioned air inlet and oil outlet 120 are both exposed inside the receiving cavity 13, so that after the supply chamber and the working chamber 20 are connected in the receiving cavity 13, liquid and gas communication can be achieved simultaneously with the working chamber 20.

[0038] The snap-fit ​​structure between the supply compartment and the working compartment 20 can be a mating of a snap-fit ​​protrusion 203 and a snap-fit ​​groove 101. For example, combined with... Figure 4 , Figure 5 As shown, the snap-fit ​​structure on the inner wall of the receiving cavity 13 of the first chamber 10 is a snap-fit ​​groove 101, and the working chamber 20 has a snap-fit ​​protrusion 203 that snaps into the snap-fit ​​groove 101.

[0039] The working chamber 20 includes a second chamber 22 and a base 21 that constitute the lower structure of the electronic atomizer 1. The inner wall of the second chamber 22 and the top surface of the base 21 enclose a second oil reservoir 200 of the electronic atomizer 1. (Reference) Figures 2 to 4As shown, the working chamber 20 includes a second chamber body 22 and a base 21. The second chamber body 22 has an inner wall that encloses and forms an annular space. The top surface of the base 21 is connected to the second chamber body 22 to close the annular space and form a second oil storage chamber 200. The top of the second chamber body 22 is provided with a first oil inlet 201. After the second chamber body 22 is connected to the first chamber body 10, the first oil inlet 201 communicates with the oil outlet 120. Under the action of gravity, the e-liquid enters the second oil storage chamber 200 sequentially through the oil outlet 120 and the first oil inlet 201. The axis of the first oil inlet 201 coincides with the axis of the oil outlet 120, or the radial range of the first oil inlet 201 partially covers the oil outlet 120.

[0040] As the e-liquid stored in the first reservoir 11 is gradually injected into the second reservoir 200, the negative pressure in the first reservoir 11 increases. When the e-cigarette 1 is tilted, inverted, or laid flat, the e-liquid in the second reservoir 200 is drawn in by the negative pressure in the first reservoir 11, causing the e-liquid to flow back into the first reservoir 11.

[0041] For example, the volume of the first oil storage chamber 11 is V1, and the volume of the second oil storage chamber 200 is V2, wherein V1 / 5 ≤ V2 < V1. Part of the e-liquid in the first oil storage chamber 11 can fill the second oil storage chamber 200, avoiding the injection of too much e-liquid at one time.

[0042] The inner wall of the working chamber 20, which encloses the second oil storage cavity 200, is provided with multiple ribs 210. These ribs 210 are circumferentially distributed on the inner wall of the second oil storage cavity 200, and adjacent ribs 210 are spaced apart to form capillary gaps. For example, the first oil inlet 201 is located on the top wall of the working chamber 20, and multiple ribs 210 protrude from the side wall of the working chamber 20, away from the first oil inlet 201. The length direction of the ribs 210 is parallel to the height direction of the side wall, and capillary gaps are formed between adjacent ribs 210. The second oil storage cavity 200 absorbs and stores e-liquid through these capillary gaps. When the negative pressure in the first oil storage cavity 11 increases, the e-liquid in the second oil storage cavity 200 is absorbed by capillary action, thereby creating resistance to the negative pressure in the first oil storage cavity 11.

[0043] For example, such as Figure 6 , Figure 7As shown, the base 21 has an upwardly protruding annular sidewall. The outer side of the annular sidewall abuts against the inner wall of the second chamber 22 to form a seal, while the inner side of the annular sidewall is constructed as part of the inner wall of the second oil storage cavity 200. The end face of the annular sidewall does not contact the top wall of the second chamber 22. The aforementioned ribs 210 can be constructed on the inner side of the annular sidewall of the base 21, meaning the ribs 210 do not contact the top wall of the second chamber 22, and the end faces of the ribs 210 opposite to the top wall are far from the first oil inlet 201. It is understood that multiple ribs 210 are spaced apart to form a capillary structure. The capillary structure and the top wall of the second chamber 22 form an oil-passing gap larger than the capillary gap, allowing the e-liquid to quickly diffuse into adjacent capillary gaps after entering the second oil storage cavity 200. This solves the problem of slow e-liquid absorption by the capillary structure.

[0044] The spacing Z between adjacent ribs 210 is 0.1-1 mm. In some examples, the spacing Z between ribs 210 is 0.3 mm. For ease of manufacturing, the spacing Z can be set to 0.5 mm or 1 mm.

[0045] The height of the rib 210 protrusion is approximately half or more than half the distance between the annular sidewall and the outer wall of the atomizing tube 30. For example, the height of the rib 210 protrusion is greater than two-thirds or more than three-fifths of the distance.

[0046] In some embodiments, the electronic atomizer 1 includes an atomizing assembly assembled in a working chamber 20. The atomizing assembly includes an atomizing tube 30 and an atomizing core 40. The atomizing tube 30 is provided with a second inlet 31 that absorbs e-liquid through a second oil storage chamber 200. The atomizing core 40 is fixed inside the atomizing tube 30 to atomize the e-liquid into an aerosol. For example, Figures 2 to 7 As shown, the working chamber 20 has a top wall opposite to the air inlet of the supply chamber. The top wall has a first positioning port 202, and the base 21 has a through-hole second positioning port 212. One end of the atomizing tube 30 is inserted into the first positioning port 202, and the other end is inserted into the second positioning port 212 to connect with the outside atmosphere. After the working chamber 20 is connected to the supply chamber, the atomizing tube 30 connects to the air inlet of the supply chamber, and outside air enters the atomizing tube 30 through the second positioning port 212 on the base 21.

[0047] Specifically, the second positioning port 212 is a countersunk hole, the large diameter section of which is inserted into the atomizing tube 30, and the small diameter section is connected to the atomizing tube 30 at one end and to the outside atmosphere at the other end.

[0048] In some embodiments, a portion of the inner wall of the second chamber 22 is arranged circumferentially around the atomizing tube 30, and ribs 210 are constructed on this portion of the inner wall, or ribs 210 are constructed on the annular sidewall of the base 21, such that the ribs 210 and the atomizing tube 30 are spaced apart to form a liquid accumulation tank, which is connected to the interior of the atomizing tube 30 through the second oil inlet 31. Part of the e-liquid stored in the second oil reservoir 200 is absorbed by the capillary gaps between the ribs 210, and part of it accumulates in the liquid accumulation tank. When the electronic atomizer 1 is used, the e-liquid in the liquid accumulation tank enters the atomizing tube 30 through the second oil inlet 31 and is absorbed by the atomizing core 40, and is heated and atomized by the atomizing core 40 to form an aerosol. The aerosol, along with the airflow generated by the user's inhalation, passes through the atomizing tube 30 and is discharged from the outlet through the air guide tube on the replenishment chamber.

[0049] In some embodiments, to prevent more e-liquid from being affected by the negative pressure of the first oil storage chamber 11, the radial distance between the rib 210 and the outer wall of the atomizing tube 30 is a capillary-effect distance. Of course, the distance can be greater than or equal to 0.1 mm. Preferably, the distance is 0.2 mm, or 0.5 mm, or 0.8 mm, or 1 mm, or 5 mm, etc.

[0050] In some embodiments, an oil guide 211 is provided between the first oil storage chamber 11 and the second oil storage chamber 200. One end of the oil guide 211 extends into the first oil storage chamber 11, and the other end extends into the second oil storage chamber 200. The e-liquid flows from the first oil storage chamber 11 to the second oil storage chamber 200 along the oil guide 211. It is understood that the oil guide 211 can quickly guide the e-liquid to a position close to the second oil inlet 31.

[0051] In some embodiments, the supply chamber and the working chamber 20 are detachably connected. The supply chamber is provided with an oil outlet 120, which communicates with the first oil storage chamber 11. A sealing plug 121 is removably provided at the oil outlet 120. The working chamber 20 is provided with a first oil inlet 201 that coincides with the oil outlet 120 on the same axis. One end of the oil guide 211 is fixed in the second oil storage chamber 200, and the other end of the oil guide 211 extends out of the first oil inlet 201 and extends along the axis toward the oil outlet 120. When the supply chamber and the working chamber 20 are connected, the oil guide 211 removes the sealing plug 121 from the oil outlet 120 and partially extends into the first oil storage chamber 11, so that the first oil inlet 201 communicates with the oil outlet 120, and the e-liquid enters the second oil storage chamber 200 along the oil guide 211.

[0052] For example, see Figure 6 , Figure 7 As shown, the oil guide 211 is constructed on the annular sidewall of the base 21, and extends vertically in a protruding manner from a portion of the annular sidewall to form an arm-shaped oil guide 211. The e-liquid can flow along the oil guide 211 into the capillary gap between the protruding ribs 210 of the annular sidewall.

[0053] In some embodiments, the oil guide 211 is provided with a guide groove, which can penetrate the oil guide 211 or run along the surface of the oil guide 211 and connect to the second oil storage chamber 200. For example, the guide groove is recessed in the surface of the oil guide 211 and connects to the capillary gap between the ribs 210, so that some e-liquid flows to the second oil storage chamber 200 and is absorbed and stored by the capillary gap, or is quickly guided to the atomizing tube 30 through the capillary gap.

[0054] In some embodiments, an oil-passing gap is provided between the oil guide 211 and the first oil inlet 201. For example, the outer peripheral surface of the oil guide 211 does not contact the inner wall of the first oil inlet 201. While the oil guide 211 guides the flow, some e-liquid can also enter the second oil storage chamber 200 through the oil-passing gap.

[0055] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
