Description

TECHNICAL FIELD

[0001] The utility model relates to electronic cigarette field, in particular to a simple and easy oiling electronic atomizer. BACKGROUND

[0002] Electronic cigarette is a new type of product based on traditional cigarette, its characteristic is through heating tobacco oil and atomizing, compared with traditional cigarette, the impurities in the smoke generated by electronic cigarette are less than traditional cigarette, and electronic cigarette is convenient to carry and no ash is produced. At present, electronic cigarette can be divided into two categories, one is the electronic cigarette that can be repeatedly filled with oil, and the other is disposable electronic cigarette. The electronic cigarette that can be repeatedly filled with oil is suitable for the electronic cigarette player who likes DIY or himself, the customer can choose different categories of tobacco oil according to his own needs and add to the oil cup (also called oil storage), and when the tobacco oil in the oil cup is exhausted, it can be added to achieve the purpose of repeated use. Disposable electronic cigarette is discarded after the first tobacco oil is exhausted or the battery is exhausted. This design does not allow customers to refill the oil cup, for example, a locking structure or a one-time destructive structure is arranged at the oil filling position of the oil cup.

[0003] The drawbacks of the traditional electronic cigarette that can be repeatedly filled with oil are that the plug on the oil cup usually needs to be disassembled, and then the tobacco oil is injected into the oil cup through the needle tube bottle (a container for storing tobacco oil). In the traditional design of the oil cup, once the plug is disassembled, it is easy to damage the sealing performance when it is reassembled to the oil cup, which often leads to the problem of oil leakage after the customer refills the oil cup for the second time. INVENTION CONTENTS

[0004] Therefore, the utility model provides a simple and easy oiling electronic atomizer, which adds a oil locking mechanism on the cup plug, does not need to disassemble the cup plug when filling oil, uses the tip of the needle tube bottle to push the flap to open to realize oil filling, and realizes double anti-leakage by using the flap and the convex column, which is simple and efficient, has little effect on the sealing performance, and avoids the problem of oil leakage after the second oil filling.

[0005] A simple and easy oiling electronic atomizer comprises:

[0006] An oil cup;

[0007] An atomizing core mounted on the oil cup; the atomizing core is located at the bottom of the oil cup;

[0008] An air passage shaft connected with the atomizing core; the air passage shaft is located at the center of the oil cup; one end of the air passage shaft is connected with the atomizing core;

[0009] A cup plug mounted on the oil cup; the cup plug is located at the inlet of the oil cup; a gas guide hole is arranged at the center of the cup plug and connected with the end of the air passage shaft away from the atomizing core; the cup plug is also provided with a mounting groove;

[0010] The oil locking mechanism is installed on the cup plug, and comprises a mounting seat in the mounting groove, a flap hinged on the mounting seat, and an elastic member connected between the mounting seat and the flap. The mounting seat is provided with an oil injection channel penetrating through the mounting seat along the axial direction parallel to the air passage shaft. The flap covers the port of the oil injection channel at the end facing the atomizing core. The elastic member provides a restoring driving force for the flap.

[0011] The oil cup is connected with a suction nozzle. The nozzle cover is detachably clamped on the oil cup. The suction nozzle is provided with a suction port communicating with the air guiding hole. The suction nozzle is further provided with a protruding column inserted into the oil injection channel.

[0012] When the oil injection is needed, the suction nozzle is detached from the oil cup. Then, the tip of the needle bottle filled with the e-liquid is inserted into the oil injection channel of the mounting seat. When the tip of the needle bottle contacts the flap, the flap is forced to turn down, so that the bottom end of the oil injection channel is opened. The e-liquid is squeezed out of the tip of the needle bottle and flows down along the inclined surface formed by the flap into the oil cup. When the injection amount of the e-liquid reaches the preset requirement, the tip of the needle bottle is pulled out of the oil injection channel, and the flap is automatically reset under the driving of the elastic member to block the bottom end of the oil injection channel. Then, the suction nozzle is reset, and the top end inlet of the oil injection channel is blocked by the protruding column on the suction nozzle. Under the double blocking of the side plate and the protruding column, the e-liquid is prevented from leaking out of the oil injection channel. Through the above design, the oil locking mechanism is added to the cup plug. When the oil is injected, the cup plug does not need to be detached. The tip of the needle bottle is used to push the flap to open to realize the oil injection. The double anti-leakage is realized by the flap and the protruding column. The operation is simple, efficient, and has little effect on the sealing, avoiding the problem of oil leakage after secondary oil injection.

[0013] In one embodiment, the oil cup is a transparent cup body and is provided with a liquid level scale mark. This design allows the customer to directly observe the remaining amount of e-liquid in the oil cup and know the remaining amount value through the liquid level scale mark.

[0014] In one embodiment, the oil cup is provided with a first clamping part, and the suction nozzle is provided with a second clamping part clamping the first clamping part. The clamping part can realize the quick disassembly and assembly of the suction nozzle, which is simple and efficient.

[0015] In one embodiment, the bottom of the mounting seat is provided with a rotating shaft penetrating the flap, and one side of the mounting seat is provided with a detachable side plate limiting the flap on the rotating shaft. The side plate and the rotating shaft are used to realize the hinged installation of the flap, which is efficient in disassembly and assembly.

[0016] In one embodiment, the elastic member is a torsional spring sleeved on the rotating shaft. The torsional spring has a simple structure and can efficiently realize the rotation reset of the flap.

[0017] In one embodiment, limiting blocks are provided on both sides of the top of the mounting base; the cup stopper is provided with a limiting groove to receive the limiting blocks; the limiting blocks and the limiting groove cooperate to limit the insertion depth of the mounting base in the cup stopper. When assembling equipment, the assembled oil-locking mechanism can be inserted into the mounting groove of the cup stopper in a modular manner, making installation simple.

[0018] In one embodiment, the mouthpiece is further provided with a pressure bar that abuts against the top of the mounting base; the pressure bar is used to press the mounting base firmly against the cup stopper, a design that prevents the mounting base from coming loose and avoids leakage of e-liquid from the mounting groove.

[0044] As shown in Figures 1 to 11 , it is a simple oil injection electronic atomizer 100 of an embodiment of the present application.

[0045] As shown in Figure 1 and Figure 2As shown, the simple e-liquid filling electronic atomizer 100 includes: an e-liquid cup 10, an atomizing coil 20 mounted on the e-liquid cup 10, a ventilation shaft 30 connected to the atomizing coil 20, a stopper 40 mounted on the e-liquid cup 10, an e-liquid locking mechanism 50 mounted on the stopper 40, and a mouthpiece 60 connected to the e-liquid cup 10. The e-liquid cup 10 is used to hold e-liquid, and the atomizing coil 20 heats and atomizes the e-liquid in the stopper 40, which is then guided to the mouthpiece 60 by the ventilation shaft 30 for the customer to inhale. The e-liquid locking mechanism 50 is designed for customer self-filling; the customer can directly fill the e-liquid cup 10 through the locking mechanism 50 after removing the mouthpiece 60, without needing to remove the stopper 40.

[0046] The following text, combined with Figures 1 to 11 Further explanation is provided for the aforementioned simple e-cigarette 100.

[0047] like Figure 2 As shown, the top opening of the oil cup 10 accommodates the stopper 40, while the atomizer coil 20 is embedded in the bottom of the oil cup 10. The air spool 30 is located at the center of the oil cup 10. One end of the air spool 30 is connected to the atomizer coil 20, and the other end of the air spool 30 is inserted into the stopper 40.

[0048] To make it easier for customers to know the remaining e-liquid and refill it in time, in some embodiments, the e-liquid cup 10 can be a transparent cup with liquid level markings (such as scale lines, triangle marks, etc.). This design allows customers to directly observe the remaining e-liquid in the e-liquid cup 10 and know the remaining value through the liquid level markings.

[0049] like Figure 2 and Figure 3 As shown, the stopper 40 is located at the inlet of the oil cup 10. (Combined with...) Figure 2 and Figure 6 As shown, the cup stopper 40 has an air guide hole 41 at its center, which connects to the end of the air shaft 30 furthest from the atomizing core 20. Figure 5 and Figure 6 The cup stopper 40 shown is also provided with a mounting groove 42 for accommodating the oil-locking mechanism 50.

[0050] like Figures 9 to 11 As shown, the oil-locking mechanism 50 includes: a mounting base 51 located in the mounting groove 42, a flap 52 hinged to the mounting base 51, and an elastic member 53 connecting the mounting base 51 and the flap 52. Figure 7 and Figure 8 As shown, the mounting base 51 has an oil filling channel 511 extending through the mounting base 51 axially parallel to the ventilation shaft 30. A flap 52 covers the port of the oil filling channel 511 facing the atomizing core 20. An elastic member 53 provides a driving force for the flap 52 to return to its original position.

[0051] For ease of installation, combined withFigure 4 , Figure 5 , Figure 7 ,as well as Figure 9 As shown, in this embodiment, limiting blocks 512 are provided on both sides of the top of the mounting base 51. The cup stopper 40 is provided with a limiting groove 43 for receiving the limiting blocks 512. The limiting blocks 512 cooperate with the limiting groove 43 to limit the insertion depth of the mounting base 51 in the cup stopper 40. When assembling the equipment, the assembled oil-locking mechanism 50 can be inserted into the mounting groove 42 of the cup stopper 40 in a modular manner, making installation simple.

[0052] like Figures 9 to 11 As shown, in this embodiment, the bottom of the mounting base 51 is provided with a rotating shaft 513 through which the flap 52 passes, and one side of the mounting base 51 is provided with a detachable side plate 514, which is used to restrict the flap 52 on the rotating shaft 513. The hinged installation of the flap 52 is achieved by using the side plate 514 and the rotating shaft 513, which has high assembly and disassembly efficiency.

[0053] Furthermore, in this embodiment, the elastic element 53 is a torsion spring sleeved on the rotating shaft 513. The torsion spring has a simple structure and can efficiently achieve the rotational reset of the flap 52. Figure 11 For example, during assembly, the flip side is first pushed into the rotating shaft 513, then the torsion spring is fitted into the rotating shaft 513, and then the side plate 514 is locked in place by the screw 54. One locking end of the torsion spring is inserted into the flip plate 52 to follow the movement of the flip plate 52, and the other locking end of the torsion spring is inserted into the side plate 514 on the other side of the mounting base.

[0054] like Figure 1 and Figure 2 As shown, the suction nozzle 60 is mounted on the cup stopper 40 and detachably snapped onto the oil cup 10. The suction nozzle 60 has an air intake 61 that communicates with the air guide hole 41. The suction nozzle 60 also has a protrusion 62 that is inserted into the oil filling channel 511.

[0055] To improve the stability of the installation, such as Figure 2 As shown, in this embodiment, the mouthpiece 60 is also provided with a pressure rod 63 that abuts against the top of the mounting base 51. The pressure rod 63 is used to press the mounting base 51 firmly onto the cup stopper 40. This design can prevent the mounting base 51 from loosening and avoid leakage of e-liquid from the mounting groove 42.

[0056] Furthermore, such as Figure 2 As shown, in this embodiment, the protruding post 62 is disposed at the bottom of the pressure rod 63, that is, the pressure rod 63 and the protruding post 62 are integrated into one piece. The stepped portion on the pressure rod 63 is used to press the mounting base 51, and the bottom end of the pressure rod 63 is inserted into the oil injection channel 511.

[0057] like Figure 1 and Figure 3As shown, for ease of assembly and disassembly, in this embodiment, the oil cup 10 is provided with a first snap-fit ​​part 11, and the suction nozzle 60 is provided with a second snap-fit ​​part 64 that engages with the first snap-fit ​​part 11. The snap-fit ​​mechanism allows for quick assembly and disassembly of the suction nozzle 60, resulting in a simple and efficient structure.

[0058] Brief description of working principle:

[0059] like Figure 3 As shown, when refilling is required, the mouthpiece 60 is detached from the e-liquid cup 10. Next, the tip of the syringe filled with e-liquid is inserted into the e-liquid filling channel 511 of the mounting base 51. Figure 6 As shown, when the tip of the syringe bottle contacts the flap 52, it forces the flap 52 to flip downwards, thereby opening the bottom of the e-liquid channel 511. E-liquid is squeezed out from the tip of the syringe bottle and flows down the slope formed by the flap 52 into the e-liquid cup 10. Once the e-liquid injection volume reaches the preset requirement, the tip of the syringe bottle is withdrawn from the e-liquid channel 511, as shown... Figure 2 As shown, the flap 52 resets itself under the drive of the elastic element 53 to seal the bottom end of the oil filling channel 511. Then, the mouthpiece 60 is reset, and the top entrance of the oil filling channel 511 is blocked by the protrusion 62 on the mouthpiece 60. Under the double sealing of the side plate 514 and the protrusion 62, e-liquid is prevented from seeping out of the oil filling channel 511.

[0060] The aforementioned simple e-cigarette 100 adds an oil-locking mechanism 50 to the cup stopper 40. When filling with oil, there is no need to remove the cup stopper 40. The tip of the syringe bottle is used to push the flap 52 to open and fill with oil. The flap 52 and the protrusion 62 achieve double leakage prevention. The operation is simple and efficient, and has little impact on the sealing performance, avoiding the problem of leakage in the oil cup 10 after secondary filling.

[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 above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
