Description

Technical Field

[0001] This invention relates to the field of electronic atomizer technology, and in particular to a variable power electronic atomizer. Background Technology

[0002] Electronic atomizers are electronic products that replace traditional cigarettes. They simulate the taste of cigarettes by atomizing e-liquid, helping consumers reduce their dependence on traditional cigarettes and thus lower their smoking frequency. Because electronic atomizers heat the e-liquid to produce inhalable vapor, they produce fewer harmful substances compared to traditional cigarettes, making them more environmentally friendly and less likely to cause harm to others. Therefore, electronic atomizers are healthier and more environmentally friendly than traditional cigarettes.

[0003] An electronic atomizer mainly consists of an atomizer and an e-liquid. The atomizer heats up when powered on, atomizing the e-liquid. The resulting mist is then inhaled by the user. The amount of mist produced depends on the efficiency of the e-liquid transfer to the atomizer and the power of the atomizer.

[0004] Chinese Patent CN 201910552042.9 discloses a power adjustment device for an electronic cigarette and an electronic cigarette. The power adjustment device for a variable power electronic atomizer includes a mounting base, a control plate fastened to the mounting base, and a rotating mechanism rotatably connected to the mounting base. The rotating mechanism faces the control plate and has at least two protruding contact portions. Each of the at least two contact portions abuts against the control plate. The control plate has at least two spaced contact elements on its surface facing the rotating mechanism. When the rotating mechanism rotates, at least one of the at least two contact portions makes electrical contact with any one of the at least two contact elements to adjust the power of the electronic cigarette. By providing at least two contact parts in the rotating structure, and adjusting the power of the electronic cigarette when either of these contact parts makes electrical contact with the contact element, the probability of poor contact is reduced, thereby improving the adjustment efficiency of the power adjustment device.

[0005] Current research on power regulation in e-cigarettes mainly focuses on how to achieve power variations, without adapting the original atomizer structure. It uses older designs to accommodate variable power control circuits. However, power variations in existing atomizers bring a series of problems that need to be addressed. These include mismatches in e-liquid supply leading to dry burning and leakage; insufficient e-liquid conduction due to rapid consumption causing atomizer burning; and uneven heating when changing power in traditional atomizers resulting in uneven atomization. All of these issues negatively impact the user experience of e-cigarettes. Summary of the Invention

[0006] This invention aims to at least solve the technical problems existing in the prior art, namely, "atomizer burning due to insufficient oil conduction caused by instantaneous oil consumption, and uneven oil atomization due to uneven heating when changing the power of traditional atomizers." To this end, this invention proposes a variable power electronic atomizer. Adjusting the atomizer power results in more uniform heating and more even oil atomization. The oil storage structure is matched to the atomizer for adaptive adjustment, preventing atomizer burning. It also improves the oil conduction rate and intracavity pressure balance at various power levels, enhancing the overall user experience.

[0007] A variable power electronic atomizer according to some embodiments of the present invention includes a housing, the housing being provided with an air inlet and a mouthpiece; comprising:

[0008] An oil storage structure is disposed within the housing, and an exhaust pressure relief structure is provided between the oil storage structure and the suction nozzle, the exhaust pressure relief structure being connected to both the oil storage structure and the suction nozzle.

The nozzle and the atomizing pipe are respectively connected to the sealing groove. The upper sealing silicone is provided with a second pressure relief hole, and the two sides of the second pressure relief hole are respectively connected to the inner cavity of the oil storage structure and the sealing groove.

[0038] The following is for reference. Figures 1-5 A variable power electronic atomizer according to an embodiment of the present invention is described.

[0039] like Figures 1-5 As shown, the variable power electronic atomizer includes a housing 100, which has an air inlet 110 and a mouthpiece 120. The housing 100 internally includes an oil storage structure 300, an atomization channel 500, and a control assembly 620. The mouthpiece 120 is located at one end of the housing 100, and the air inlet 110 is located at the other end. The oil storage structure 300 is located inside the housing 100, and an exhaust pressure relief structure is provided between the oil storage structure 300 and the mouthpiece 120. The exhaust pressure relief structure connects the oil storage structure 300 and the mouthpiece 120, allowing external air to enter the oil storage structure 300 through the exhaust pressure relief structure, thus maintaining pressure balance inside the oil storage structure 300.

[0040] The atomizing tube 500 is located inside the housing 100. One end of the atomizing tube 500 is connected to the mouthpiece 120, and the other end is connected to the air inlet 110. The oil storage structure 300 encloses the atomizing tube 500. A three-wire heating atomizer 610 is installed inside the atomizing tube 500. An oil guide window 510 is provided in the atomizing tube 500 corresponding to the position of the three-wire heating atomizer 610. The oil guide window 510 is connected to the oil storage structure 300 and the three-wire heating atomizer 610 respectively. The atomizing tube 500 is provided with a first pressure relief hole 520, which penetrates the side wall of the atomizing tube 500 and is connected to the oil storage structure 300.

[0041] Specifically, the first pressure relief hole 520 of the atomizing pipe 500 and the exhaust pressure relief structure are used in combination to promote pressure balance inside the oil storage structure 300. When the device switches operating power, the oil consumption rate increases significantly. In order to maintain a stable oil flow from the oil storage structure 300 to the three-wire heating atomizer 610, the first pressure relief hole 520 and the exhaust pressure relief structure are set to promote pressure balance inside the oil storage structure 300, ensure the oil flow rate, and prevent the three-wire heating atomizer 610 from burning.

[0042] In order to increase the oil inlet area, the atomizing pipe 500 in this embodiment eliminates the commonly used multi-hole oil guiding structure and instead sets an oil guiding window 510 in the concentrated heating area of ​​the three-wire heating atomizer 610 to increase the oil guiding speed and prevent the coil from burning due to insufficient oil guiding caused by the power adjustment.

[0043] The control component 620 is disposed within the housing 100 and is electrically connected to the three-wire heating atomizer 610. The control component 620 is equipped with a power switching button 630, which is located on the surface of the housing 100. The user can switch the output power of the three-wire heating atomizer 610 using the power switching button 630, providing a variety of vaping experiences.

[0044] In this embodiment, compared with the three-wire heating element of the atomizer in this embodiment, which is used in existing electronic atomizers with dual-wire heating elements, the three-wire heating element generates more uniform heat and has a larger heating area than the dual-wire heating element, thus heating a larger area of ​​e-liquid on the atomizer. This is because during the heating process, not the entire heating element heats up, but rather the heating circuitry generates heat to atomize the e-liquid. The heat generated by the heating circuitry, the heating area, and the wicking speed greatly affect the overall atomization effect. Using a three-wire heating element increases the heating area of ​​the atomizer, thereby heating more e-liquid. The three-wire heating element is a well-known technical solution, and its structure will not be described in detail in this embodiment. The atomizer mainly consists of a wicking part and a heating part; the wicking part can be porous ceramic, and the heating part is a heating element.

[0045] According to the heat calculation formula Q = Pt, where P = carrier power and t = heating time, when the total heat generated by a dual-wire heating element and a triple-wire heating element are the same (i.e., the output power is equal), the heat generated by each circuit of the dual-wire and triple-wire heating elements is different. Specifically, when the power reaches 16W, the power of each heating circuit of the dual-wire heating element is 8W. Calculated based on a single-port extraction time of 2 seconds, the heat generated by each heating circuit is Q = Pt = 8W * 2s = 16 Joules. When the power reaches 16W, the power of each heating circuit of the triple-wire heating element is 16 / 3 = 5.33W. Calculated based on a single-port extraction time of 2 seconds, the heat generated by each heating circuit is Q = Pt = 5.33W * 2s = 10.66 Joules.

[0046] When atomizers operate at the same power, a single-circuit heating element in a dual-wire atomizer generates 1.5 times the heat of a triple-wire atomizer. At 16W, a single heating circuit in a dual-wire atomizer generates 16 joules of heat, which can easily lead to excessive heat in certain areas but insufficient e-liquid supply, resulting in burnt coils and significantly impacting the user's vaping experience and health. Triple-wire atomizers, with an additional heating circuit, not only avoid this problem at high power levels but also provide a larger heating area compared to dual-wire atomizers, resulting in a finer atomization. Furthermore, the addition of a heating circuit allows for higher power handling compared to a two-circuit atomization structure, increasing the atomizer's output power and providing consumers with a wider range of vaping options.

[0047] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, an air intake vent 110 is equipped with an air adjustment mechanism to regulate the airflow rate. Specifically, the air intake volume of the air intake vent 110 can be adjusted to meet the needs of different consumers. It allows switching between mouth-inhalation and light-lung modes, satisfying the need for inhaling large amounts of vapor.

[0048] In a further embodiment, such as Figure 2 and Figure 4 As shown, the air regulating structure includes an air regulating valve 210, which is slidably connected to the end face of the air inlet 110 and is used to adjust the opening area of ​​the air inlet 110. The housing 100 is provided with a sliding groove 130, in which the air regulating valve 210 slides, and the air inlet 110 passes through the bottom of the sliding groove 130.

[0049] Specifically, the air intake of the air inlet 110 is adjusted by the air regulating valve 210 to achieve both mouth inhalation and lung inhalation. The air inlet 110 extends through the bottom of the sliding groove 130, and the air regulating valve 210 slides within the sliding groove 130. When the cover of the air regulating valve 210 partially blocks the air inlet 110, the air intake changes. Users can adjust the air intake of the air inlet 110 according to their own inhalation needs, providing a customized inhalation experience.

[0050] It should be understood that using the airflow regulating valve 210 to adjust the airflow of the air inlet 110 is not the only implementation method. In some other embodiments, multiple air inlets 110 can be provided, with the default mode having the largest airflow. Users can reduce the airflow by covering the air inlet 110 with their fingers. This invention does not elaborate on the structure for adjusting the airflow of the electronic atomizer air inlet 110. It should be understood that, without departing from the basic concept of this invention, flexible changes to the structure for adjusting the airflow of the electronic atomizer air inlet 110 should be considered within the scope of protection defined by this invention.

[0051] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the exhaust pressure relief structure includes an upper sealing silicone 410, which covers the top of the oil storage structure 300. The upper sealing silicone 410 has a sealing groove 411, and an oil-absorbing cotton 420 is placed inside the sealing groove 411. The nozzle 120 and the atomizing pipe 500 are respectively connected to the sealing groove 411. The upper sealing silicone 410 has a second pressure relief hole 412, and the two sides of the second pressure relief hole 412 are respectively connected to the inner cavity of the oil storage structure 300 and the sealing groove 411.

[0052] Specifically, one end of the atomizing tube 500 protrudes from the bottom of the sealing groove 411, while the bottom of the mouthpiece 120 extends into the sealing groove 411, with a certain distance between the mouthpiece 120 and the atomizing tube 500. The thickness of the absorbent cotton 420 is equal to the spacing, and the absorbent cotton 420 has openings corresponding to the areas of the atomizing tube 500 and the mouthpiece 120. External air can enter the second pressure relief hole 412 through the porous absorbent cotton 420 and then enter the interior of the oil storage structure 300, thereby achieving air pressure balance in the oil storage structure 300. Furthermore, the absorbent cotton 420 can absorb liquefied backflowing oil at the mouthpiece 120, preventing oil leakage and effectively improving the vaping experience.

[0053] The second pressure relief hole 412 can effectively introduce external air pressure into the oil storage structure 300, ensuring that the internal air pressure of the oil storage structure 300 is balanced with the external air pressure, thereby ensuring that the e-liquid can be smoothly introduced into the three-wire heating atomizer 610.

[0054] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the end of the mouthpiece 120 near the absorbent cotton 420 is wrapped with a ring of airway sealing silicone 430. The airway sealing silicone 430 is used to seal the connection gap around the mouthpiece 120. Specifically, the electronic atomizer housing 100 in this embodiment includes an outer shell, an inner shell, and a bottom shell. The mouthpiece 120 is disposed on the outer shell, the air inlet 110 is disposed on the bottom shell, and the exhaust pressure relief structure and the oil storage structure 300 are disposed inside the inner shell. When the outer shell and the inner shell are assembled, a connection gap is left between the periphery of the mouthpiece 120 and the inner shell. In order to prevent oil from entering between the outer shell and the inner shell from the connection gap, the airway sealing silicone 430 is used to seal the connection gap, and the airway sealing silicone 430 can improve the airtightness of the exhaust pressure relief structure.

[0055] It should be understood that using airway sealing silicone 430 to seal the connection gap between the nozzle 120 and the inner shell is not the only implementation method. In some other embodiments, the outer shell and the inner shell can be integrally formed so that the nozzle 120 is connected to the exhaust pressure relief structure.

[0056] In some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, the opening area of ​​the oil guide window 510 covers the side wall of the three-wire heating atomizer 610. Specifically, existing porous pipes have limited contact area between the oil in the oil storage structure 300 and the atomizer due to their small opening area, making it difficult to meet the atomization requirements under high power conditions. Furthermore, the oil entering the atomizer from the opening still needs to be transferred to the heating element within the atomizer, resulting in uneven oil distribution inside the atomizer. This can lead to insufficient oil in certain areas of the heating element during operation, increasing the risk of burning. In this embodiment, the oil guide window 510 adopts a large opening structure, allowing the side wall of the atomizer to fully contact the oil in the oil storage structure 300. This results in more uniform oil conduction within the atomizer, ensuring consistent oil contact across all heating elements, preventing burning of any element, and improving the amount of oil atomized and the vaping experience.

[0057] In some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, the first pressure relief hole 520 is located above the oil guide window 510. Specifically, the first pressure relief hole 520 can guide the flowing air in the atomizing pipe 500 into the oil storage structure 300, ensuring that the internal air pressure of the oil storage structure 300 is balanced with the external air pressure, thereby ensuring that the oil can be smoothly guided into the atomizer. Unlike the second pressure relief hole 412, the air in the atomizing pipe 500 is in a flowing state due to the user's inhalation, and the airflow entering the first pressure relief hole 520 is greater than that of the second pressure relief hole 412, resulting in a better effect on balancing the internal and external air pressure. Even if the oil-absorbing cotton 420 of the exhaust pressure relief structure absorbs too much oil and blocks the second pressure relief hole 412, the first pressure relief hole 520 can still work normally.

[0058] In some embodiments of the present invention, such as Figure 2 As shown, the oil storage structure 300 includes an oil storage cup 310 and an oil storage cotton 320. The oil storage cotton 320 is filled inside the oil storage cup 310. The top of the oil storage cup 310 is connected to the upper sealing silicone 410, and the bottom is connected to the lower sealing silicone 330. The atomizing pipe 500 passes through the upper sealing silicone 410 and the lower sealing silicone 330.

[0059] Specifically, the top and bottom of the oil reservoir 310 are respectively sealed with upper sealing silicone 410 as the top and lower sealing silicone 330 as the bottom, forming a sealed cavity. Using the side wall of the atomizing pipe 500 as the inner wall of the oil reservoir, and employing oil storage cotton 320, can prevent oil leakage from the oil reservoir 310 and improve the oil guiding effect.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the control component 620 includes a display screen 640, which is electrically connected to the control component 620 and disposed on the surface of the housing 100. Specifically, the display screen 640 can identify the current remaining oil level, battery level, and output power of the device at any time, making it more intuitive and convenient for consumers to use.

[0061] In some embodiments of the present invention, such as Figure 2 As shown, the device includes a power supply component 650, which is disposed within the housing 100 and located on one side of the oil storage structure 300. The power supply component 650 is electrically connected to the control component 620. Specifically, the power supply component 650 adopts a side-mounted structure, which shortens the device length, improves the grip, and prevents oil from seeping into the power supply component 650, making it safer to use.
