Description

Technical Field

[0001] The present invention relates to the technical field of oil atomization, and particularly to an atomizer and an electronic cigarette using the atomizer. Background Art

[0002] An electronic cigarette is a newly emerging smoking electronic product. Since the electronic cigarette does not produce toxic and harmful substances such as tar and carbon monoxide, it does not affect health, and thus the electronic cigarette is highly favored by consumers. In current electronic cigarette products, the oil storage cavity for storing oil is directly connected to the atomization cavity for generating smoke. When the oil flows from the oil storage cavity into the atomization cavity, it is extremely easy to leak between the oil storage cavity and the atomization cavity, resulting in an oil leakage phenomenon and affecting the user experience.

[0003] The above content is only used to assist in understanding the technical solution of the present application, and does not represent an admission that the above content is prior art. Summary of the Invention

[0012] Optionally, the cross-sectional profile of the first oil reservoir housing is oval;

[0013] And / or, the cross-sectional profile of the second oil reservoir housing is oval.

[0014] Optionally, the atomization core assembly includes an atomization core body and an electric heating wire wound around the outside of the atomization core body. The atomizer includes a power module, the power module is electrically connected to the electric heating wire, and the oil liquid in the atomization chamber is adsorbed within the atomization core body.

[0015] Optionally, the atomization core assembly further includes a sealing sleeve, and the sealing sleeve is sleeved on the outside of the atomization core body.

[0016] The present invention also provides an electronic cigarette, including an atomizer and an electronic cigarette body connected to the atomizer.

When atomization by the atomization core assembly within the atomization chamber is required, a part of the oil liquid in the main oil reservoir can be controlled to enter the auxiliary oil reservoir by opening the switch structure, and then enter the atomization chamber from the auxiliary oil reservoir for atomization.

[0032] The present invention provides an atomizer.

[0033] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the atomizer includes a housing 10 and an atomization core assembly 20. A main oil chamber 11, an auxiliary oil chamber 12, and an atomization chamber 13 are provided inside the housing 10. The housing 10 is further provided with an air outlet 15 communicating with the atomization chamber 13. The atomization core assembly 20 is disposed inside the atomization chamber 13. The atomization chamber 13 communicates with the auxiliary oil chamber 12. A switch structure 30 for conducting or closing the auxiliary oil chamber 12 and the main oil chamber 11 is provided inside the housing 10 to control the oil liquid in the main oil chamber 11 to enter the atomization chamber 13 through the auxiliary oil chamber 12.

[0034] In this embodiment, the material of the housing 10 can be a plastic material with good heat insulation performance, so that users will not be scalded due to the high temperature inside during the smoking process. The outer shape of the housing 10 can be designed in various ways. For example, the cross-sectional contour of the housing 10 can be oval or fusiform, etc. Such shapes conform to the ergonomic design and are convenient for users to hold.

[0035] Understandably, the number of auxiliary oil tanks 12 in this application can be set to multiple, such as two, three, or more. Multiple auxiliary oil tanks 12 are connected in series and conduct electricity. In this way, when the oil in the main oil tank 11 passes through multiple auxiliary oil tanks 12 in sequence and then enters the atomization chamber 13, the risk of oil leakage is further reduced by flowing layer by layer.

[0036] The on and off of the main oil tank 11 and the auxiliary oil tank 12 in this application are controlled by a switch structure 30. As Figure 5 shown, the switch structure 30 can be an electromagnet valve switch controlled by electricity. A communication port is provided between the main oil tank 11 and the auxiliary oil tank 12. When the power is turned on, the electromagnet valve switch acts to control the electromagnet to block or conduct the communication port, thereby realizing the blocking or conduction between the main oil tank 11 and the auxiliary oil tank 12. Of course, in other embodiments, the switch structure 30 can also be driven by a small motor (such as a stepper motor) to control the switch to block or conduct the communication port, or can be controlled by mechanical pushing. This design does not make specific limitations on this.

[0037] Therefore, for the atomizer of the technical solution of the present invention, when the atomization core assembly 20 in the atomization chamber 13 needs to be atomized, a part of the oil in the main oil tank 11 can be controlled to enter the auxiliary oil tank 12 by opening the switch structure 30, and then enter the atomization chamber 13 from the auxiliary oil tank 12 for atomization. Since the oil tank is divided into two parts, the amount of oil in the auxiliary oil tank 12 is relatively small, so that the pressure of the oil in the auxiliary oil tank 12 is also small, and the oil is not easy to penetrate and flow. Therefore, when the oil enters the atomization chamber 13, it is not easy to penetrate or leak between the auxiliary oil tank 12 and the atomization chamber 13. That is, by decomposing the oil tank, the pressure and fluidity of the oil between the atomizer oil tank and the atomization chamber 13 are reduced, and the switch structure 30 maintains a closed environment in the oil tank, so that the oil tank is less affected by external air pressure and temperature changes, and the possibility of oil leakage is greatly reduced.

[0038] Refer to Figure 3 , in an embodiment of this application, the main oil tank 11 and the auxiliary oil tank 12 are arranged up and down in the housing 10, and the switch structure 30 is in communication with the bottom of the main oil tank 11. In this embodiment, the main oil tank 11 is located above the auxiliary oil tank 12. Therefore, when the switch structure 30 is opened to allow the oil in the main oil tank 11 to enter the auxiliary oil tank 12, the oil can flow directly into the auxiliary oil tank 12 along the flow, and the efficiency of oil circulation is relatively high; and the switch structure 30 communicates with the bottom of the main oil tank 11, which can prevent oil from remaining at the bottom of the main oil tank 11, so that all the oil in the main oil tank 11 can be utilized.

[0039] Of course, in other embodiments, the main oil tank 11 and the auxiliary oil tank 12 can also be arranged in other ways, including but not limited to front and back arrangement, left and right arrangement, and internal and external wrapping arrangement.

[0040] In an embodiment of the atomizer of the present application, the capacity of the main oil storage chamber 11 is defined as x 1 and the capacity of the auxiliary oil storage chamber 12 is x 2 , then the relationship is satisfied: 0.1 < x 2 / x 1 < 1. The ratio value of the capacity of the auxiliary oil storage chamber 12 to the capacity of the main oil storage chamber 11 should not be too large or too small. If it is too large, the capacity of the auxiliary oil storage chamber 12 is relatively large compared to the capacity of the main oil storage chamber 11. Therefore, the amount of oil stored in the auxiliary oil storage chamber 12 is also relatively large, resulting in a relatively large pressure in the auxiliary oil storage chamber 12. At the same time, the fluidity of the oil is also better. In this way, when the oil flows from the auxiliary oil storage chamber 12 into the atomization chamber 13, leakage is more likely to occur. If it is too small, the capacity of the auxiliary oil storage chamber 12 is relatively small compared to the capacity of the main oil storage chamber 11, so the amount of oil that can be stored is too small. Therefore, the amount of oil available for atomization is also relatively small, and the amount of smoke that the user can inhale is also relatively small, which cannot meet the user's needs. Moreover, if the amount of oil flowing into the atomization core assembly 20 is relatively small, it is easy to cause the phenomenon of dry burning. Therefore, in the present application, the ratio value of the capacity of the auxiliary oil storage chamber 12 to the capacity of the main oil storage chamber 11 is designed within the range of not less than 0.1 and not higher than 1.

[0041] It can be understood that in actual application, the ratio value of the capacity of the auxiliary oil storage chamber 12 to the capacity of the main oil storage chamber 11 can specifically be 0.2, 0.25, 0.28, 0.3, 0.33, 0.35, 0.4, 0.5 or 0.8.

[0042] In an embodiment of the present application, the atomization chamber 13 is located on the side of the auxiliary oil storage chamber 12 away from the main oil storage chamber 11 and is connected to the bottom of the auxiliary oil storage chamber 12. In this embodiment, the main oil storage chamber 11, the auxiliary oil storage chamber 12 and the atomization chamber 13 are arranged in sequence from top to bottom in the housing. Thus, when the user needs to inhale smoke, by turning on the switch structure 30, the oil can enter the atomization chamber 13 for atomization successively through the main oil storage chamber 11 and the auxiliary oil storage chamber 12 by relying on its own gravity, without the need to set up an additional oil guiding structure to guide the flow of the oil. At the same time, connecting the atomization chamber 13 to the bottom of the auxiliary oil storage chamber 12 enables all the oil in the auxiliary oil storage chamber 12 to enter the atomization chamber 13 and is not likely to remain at the bottom of the auxiliary oil storage chamber 12, which improves the utilization rate of the oil and further reduces the risk of oil leakage between the auxiliary oil storage chamber 12 and the atomization chamber 13.

[0043] In the present application, continue to refer to Figure 3, an air flow channel 14 is further provided in the outer shell 10, and the air flow channel 14 communicates with the atomization chamber 13. Specifically, the air flow channel 14 can be arranged outside the main oil chamber 11 and the auxiliary oil chamber 12. After the oil liquid entering the atomization chamber 13 is atomized to generate smoke, the smoke can enter the outer air flow channel 14 for the user to inhale conveniently. Moreover, the installation structure of the atomizer is relatively simple, the internal space is compact, and it is convenient to carry.

[0044] Further, please refer to Figure 4 , in the auxiliary oil chamber 12 of the present application, an oil blocking member 50 is provided to control the fluidity of the oil liquid in the auxiliary oil chamber 12. Specifically, the oil blocking member 50 can be an oil absorption cotton, and the oil absorption cotton can be filled in the auxiliary oil chamber 12. Thus, when the oil liquid in the main oil chamber 11 enters the auxiliary oil chamber 12, it can be adsorbed by the oil absorption cotton, and then penetrate into the atomization chamber 13 through the oil absorption cotton for atomization. It can be understood that by setting the oil blocking member 50, the oil liquid entering the auxiliary oil chamber 12 is not easy to flow, has weak fluidity, and thus is not easy to cross and leak between the auxiliary oil chamber 12 and the atomization chamber 13, further reducing the possibility of oil leakage.

[0045] Refer to Figure 2 , in an embodiment of the present application, the main oil chamber 11 includes a first oil chamber housing 111, the auxiliary oil chamber 12 includes a second oil chamber housing 121, the first oil chamber housing 111 and the second oil chamber housing 121 are connected to each other and are detachably arranged in the outer shell 10.

[0046] Specifically, both the first oil chamber housing 111 and the second oil chamber housing 121 can be made of plastic material, which has good heat insulation performance and strong impact resistance, can protect the oil liquid, and has high safety. In this embodiment, the first oil chamber housing 111 and the second oil chamber housing 121 can be an integral structure. By detachably arranging the first oil chamber housing 111 and the second oil chamber housing 121 in the outer shell 10, the housing of the atomizer oil chamber and the outer shell 10 are designed as a split type, which is convenient for disassembling the oil chamber housing for maintenance and repair. At the same time, it is also convenient to take out the first oil chamber housing 111 and the second oil chamber housing 121 for refueling and other operations, improving the convenience for users in daily use.

[0047] Furthermore, the cross-sectional profile of the first oil storage housing 111 of the present application is elliptical; and / or, the cross-sectional profile of the second oil storage housing 121 is elliptical. It can be understood that, on the one hand, such a design of the ellipse conforms to the ergonomic design, facilitating operations such as refueling and maintenance by hand; on the other hand, designing the cross-sectional profiles of the first oil storage housing 111 and / or the second oil storage housing 121 as ellipses makes the shell walls of the first oil storage housing 111 and / or the second oil storage housing 121 without corners and relatively smooth. Therefore, when the oil liquid flows on the inner wall surface, the residence time on the inner wall surface is also short, thereby greatly improving the oil liquid flow efficiency and the utilization rate of the oil liquid.

[0048] Of course, in other embodiments, the cross-sectional profiles of the first oil storage housing 111 and the second oil storage housing 121 can also be other shapes, including but not limited to circular, square, etc.

[0049] In an embodiment of the atomizer of the present application, the atomization core assembly 20 includes an atomization core body 21 and a heating wire wound around the outside of the atomization core body 21. The atomizer includes a power module 40, and the power module 40 is electrically connected to the heating wire. The oil liquid in the atomization chamber 13 is adsorbed in the atomization core body 21. Among them, the atomization core body 21 can be a cotton core, which has a good taste, a high reduction degree of the oil liquid, and a relatively thick smoke volume. Of course, the atomization core body 21 can also be a ceramic core, which is stable and durable, easy to clean, and not prone to the phenomenon of core burning; and the heating wire can be a stainless steel wire, nickel wire, or nickel-chromium alloy wire, etc. with good heat transfer performance and low cost. In practical applications, when the heating wire is connected to the power module 40, the heating wire generates heat to atomize the oil liquid adsorbed in the atomization core body 21, and the oil liquid generates smoke after being heated, which is supplied to the smoker through the air flow channel 14.

[0050] Furthermore, referring to Figure 2 、 Figure 3 , the atomization core assembly 20 of the present application further includes a sealing sleeve 22, and the sealing sleeve 22 is sleeved on the outside of the atomization core body 21. The sealing sleeve 22 can be a silica gel sleeve. It can be understood that by providing the sealing sleeve 22, the oil liquid adsorbed in the atomization core body 21 is not likely to leak, and it acts with the heated heating wire for atomization, improving the utilization rate of the oil liquid in the atomization core body 21.

[0051] The present invention also proposes an electronic cigarette, which includes an atomizer and an electronic cigarette body connected to the atomizer. The specific structure of the atomizer refers to the above embodiments. Since this electronic cigarette adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0052] In one embodiment, the atomizer is plugged and cooperated with the e-cigarette body. The power supply module 40 is arranged in the e-cigarette body. After the atomizer is plugged and cooperated with the e-cigarette body, it is conducted with the power supply module 40 through the electrode. Thus, the atomization process of the atomizer can be controlled by pressing the button on the e-cigarette body.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
