Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to an oil-leakage-proof structure for an atomizer and an atomizer. Background Technology

[0002] An atomizer consists of a liquid filling a reservoir. During use, the liquid seeps through a wicking component into the heating element for atomization, achieving the desired atomization effect. However, existing atomizers often suffer from leakage during transportation or storage due to poor sealing. To improve sealing, current technology typically uses silicone plugs at the air inlet and outlet, but this method is inconvenient to install and has poor sealing stability. Some atomizers use a seal added to the airflow channel of the atomizing tube, but this reduces the atomization space or airflow channel, resulting in poor performance. Utility Model Content

[0003] To address the problems existing in the prior art, an oil leakage prevention structure and atomizer are provided. The upper and lower sealing silicone seals the upper and lower ends of the oil storage chamber and the oil guide chamber, respectively. The lower sealing silicone and the sealing cap are sealed to the sealing rod to seal the internal air passage of the atomizing tube. A sleeve and oil storage cotton are set between the oil cup and the atomizing tube to form a buffer structure, thereby improving the sealing performance and sealing stability of the atomizer while ensuring its performance.

[0041] Example 1

[0042] Please see Figure 1-2 The atomizer shown includes a base 1, an oil cup 2, an oil filling plug 19, a side cover 12, an electrode pin 13, a magnetic component 14, an airway silicone 15, a lower sealing silicone 10, a sleeve 4, an oil storage cotton 5, an atomizing tube 6, a sealing rod 11, an upper sealing silicone 9, and a sealing cap 3.

[0043] The oil cup 2 has openings at both its upper and lower ends. The upper side of the base 1 has a first trapezoidal buckle, and the inner side of the lower opening of the oil cup 2 has a first groove corresponding to the first trapezoidal buckle. The base 1 is connected to the inner side of the lower opening of the oil cup 2 by the first trapezoidal buckle and the first groove. The bottom of the base 1 has an air inlet 101, through which air is supplied to the atomizer. The upper opening of the oil cup 2 has a mouthpiece 201 with an internal air passage. A sealing cap 3 achieves a sealed connection between the outer side of the mouthpiece 201 and its internal air passage through interference. The lower center of the sealing cap 3 has an installation groove communicating with the internal air passage. The side of the oil cup 2 has an oil filling hole. An oil filling plug 19 is detachably and resealably installed in the oil filling hole through interference, thus achieving a seal. When the atomizing liquid inside the atomizer is used up, the oil filling plug 19 can be pulled out, and oil can be filled into the oil cup through the oil filling hole. After filling, the oil filling plug 19 is reinserted.

[0044] Specifically, the sealing cap 3 is made of silicone.

[0045] Specifically, the oil cup 2 is made of a transparent material, allowing observation of the usage of the atomizing liquid inside.

[0046] The side cover 12 is detachably fastened to the outer side of the oil cup 2 and the base 1. Specifically, the side cover 12 is detachably fastened to the side of the oil cup 2 where the oil filling hole is located, and covers the oil filling plug 19 to prevent the oil filling plug 19 from being exposed. In this embodiment, the upper end and both sides of the side cover 12 are provided with a second slot and a third slot (not shown in the figure), respectively. The upper end of the oil cup 2 is provided with a second trapezoidal buckle corresponding to the second slot, and the side of the base is provided with a third trapezoidal buckle corresponding to the third slot. The second slot and the third slot are fastened to the second trapezoidal buckle and the third trapezoidal buckle, respectively, thereby realizing the detachable connection between the side cover 12, the oil cup 2, and the base 1.

[0047] Two electrode pins 13 are provided, which are installed on the side of the side cover 12. Figure 2 (In the figure, electrode nail 13 is not shown because it is not cut through).

[0048] Two magnetic components 14 are provided, which are respectively embedded in the upper and lower ends of the outer side cover 12, thereby connecting with the atomizing rod through magnetic attraction.

[0049] The airway silicone 15 is disposed between the side cover 12 and the base 1 to prevent air leakage between the side cover 12 and the base 1, which would result in poor atomization. In this embodiment, the side of the base 1, the airway silicone 15, and the side cover 12 are provided with interconnected air holes 18 to achieve air control.

[0050] Please refer to further information. Figure 3 The atomizing tube 6 is located inside the oil cup 2, forming an atomizing chamber that communicates with the internal air passage of the mouthpiece 201. The atomizing chamber contains an oil-guiding cotton 7 and a heating element 8. The heating end of the heating element 8 is connected to the interior of the oil-guiding cotton 7. The side of the atomizing tube 6 has four rectangular first oil inlet holes 601 with dimensions of length × width = 2.8 mm × 4.6 mm. The atomized liquid enters the oil-guiding cotton through the first oil inlet holes 601 and is heated and atomized by the heating end of the heating element 8.

[0051] Specifically, the heating element 8 is a heating wire, and the positive and negative electrodes of the heating element 8 are electrically connected to two electrode nails 13 respectively.

[0052] The sleeve 4 is positioned between the oil cup 2 and the atomizing tube 6, and the oil storage cotton 5 is positioned between the sleeve 4 and the atomizing tube 6. The sleeve 4 has eight second oil inlet holes 401 with a diameter of 1 mm on its side, and the second oil inlet holes 401 and the first oil inlet holes 601 are staggered. The first oil inlet hole 601 is located between the oil storage cotton 5 and the oil guiding cotton 7, and the second oil inlet hole 401 is located between the oil storage chamber 17 and the oil guiding chamber 16. The oil storage chamber 17 is formed between the oil cup 2 and the sleeve 4, and the oil guiding chamber 16 is formed between the sleeve 4 and the atomizing tube 6. The atomizing liquid enters the oil guiding chamber 16 from the oil storage chamber 17 through the second oil inlet holes 401, and then enters the atomizing chamber through the first oil inlet holes 601, thus forming a buffer structure to slow down the flow rate of the atomizing liquid, ensuring uniform oil intake in the atomizing chamber and preventing leakage caused by the atomizing liquid directly entering the atomizing chamber through the first oil inlet hole 601 under external force.

[0053] Upper sealing silicone 9 and lower sealing silicone 10 are respectively sealed to the upper and lower ends of the oil guiding cavity 16 and the oil storage cavity 17. Specifically, the upper sealing silicone 9 achieves a seal between the upper end of the oil guiding cavity 16 and the upper end of the oil storage cavity 17 and the inner wall of the oil cup 2, the inner wall of the sleeve 4, and the outer wall of the atomizing tube through interference. The lower sealing silicone 10 achieves a seal between the lower end of the oil guiding cavity 16 and the lower end of the oil storage cavity 17 and the inner wall of the oil cup 2 and the base 1, the outer wall of the sleeve 4, and the outer wall of the atomizing tube through interference. At the same time, the lower sealing silicone 10 can also achieve a sealed connection between the oil cup 2 and the base 1.

[0054] Specifically, an air intake chamber is formed between the lower sealing silicone 10 and the base 1, and the air intake hole 101 and the air hole 18 communicate with the air intake chamber. For further details, please refer to [link / reference needed]. Figure 4 and Figure 5 The upper sealing silicone 9 and the lower sealing silicone 10 are respectively provided with an upper sealing hole 901 and a lower sealing hole 1001 in the center. The internal air passage of the nozzle 201 is connected to the atomizing chamber inside the atomizing tube 6 through the upper sealing hole 901, and the air inlet chamber is connected to the atomizing chamber inside the atomizing tube 6 through the lower sealing hole 1001, so that the air inlet chamber, the atomizing chamber and the internal air passage of the nozzle 201 form an atomizing channel.

[0055] The upper end of the sealing rod 11 is installed in the mounting hole to achieve a seal through interference. The other end is detachably inserted from top to bottom into the internal air passage of the nozzle 201, the upper sealing hole 901, the atomizing chamber inside the atomizing tube 6, the oil guide cotton 7, and the lower sealing hole 1001, and extends into the air inlet chamber. The lower end of the sealing rod 11 is connected to the lower sealing hole 1001 through interference sealing, thereby achieving a seal in the atomizing chamber.

[0056] Specifically, the sealing rod 11 is made of glass fiber.

[0057] Specifically, the thickness of the lower end of the sealing rod 11 interfering with the lower sealing hole 1001 is 0.25mm, and the height is 4.5mm, to avoid the problem of poor sealing effect due to being too thin and insufficient atomization space due to being too thick.

[0058] Specifically, in this embodiment, when using the atomizer, simply squeeze the sealing cap 3 to pull out the sealing rod 11 to connect the atomization channel, and use it with the atomizing rod. During use, air enters the air intake chamber through the air inlet 101, enters the atomization chamber through the lower sealing hole 1001, reacts to form smoke, and then exits through the internal air passage of the mouthpiece 201, making it convenient to use.

[0059] This embodiment achieves effective sealing of the oil storage chamber 17, oil guiding chamber 16, and atomizing chamber through the oil filling plug 19, sealing cap 3, upper sealing silicone 9, lower sealing silicone 10, and sealing rod 11. This seals the atomizing liquid within the oil storage chamber 17, oil guiding chamber 16, and atomizing chamber, preventing leakage. Simultaneously, the sleeve 4 and oil-retaining cotton 5 provide a buffering effect for the atomizing liquid, further improving the sealing effect and stability. Furthermore, since the upper sealing hole 901 does not interfere with the sealing rod 11, it avoids the problem of insufficient atomization space caused by the small diameter of the sealing hole when the upper sealing silicone or the sealing silicone inside the atomizing chamber interferes with the sealing rod, a problem common in traditional atomizers.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
