Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to an oil tank and an electronic cigarette with a spiral exhaust structure. Background Technology

[0002] As people become more health-conscious and aware of the harmful effects of tobacco, e-cigarettes have emerged. E-cigarettes typically deliver e-liquid to users through an atomizer. During the e-liquid's production, harmful substances such as nicotine and tar are removed, eliminating their harmful effects. Furthermore, because e-liquids lack nicotine and tar, users' cravings gradually decrease, thus e-cigarettes can aid in smoking cessation. With the rapid development of e-cigarettes, designers are constantly considering environmental issues and prioritizing the consumer experience.

[0003] In current e-cigarette products on the market, the atomizer coil is located within the e-liquid tank. The heating wire in the atomizer coil heats the e-liquid permeated with heating cotton, producing vapor. This vapor travels outward from the inside of the atomizer coil and is then inhaled. In this structure, due to the sealed design of the e-liquid tank, it is prone to under-pressure when the e-liquid level decreases, or over-pressure when vapor overflows into the tank. This can affect the heating effect of the e-liquid. Utility Model Content

[0004] In view of the above technical problems, this utility model provides an oil tank and an electronic cigarette with a spiral exhaust structure to solve the overpressure or underpressure defects of the oil tank in the prior art of electronic cigarettes.

[0005] Other features and advantages of this invention will become apparent from the following detailed description, or may be learned in part by practice of this invention.

[0006] According to one aspect of this utility model, an oil tank with a spiral exhaust structure is disclosed, including an oil tank body, an atomizing core assembly disposed inside the oil tank, the atomizing core assembly including an atomizing core outer part, an exhaust pipe sleeved on the top of the atomizing core outer part, and an exhaust sleeve sleeved on the outer surface of the exhaust pipe, the surface of the exhaust pipe having a plurality of exhaust grooves, the plurality of exhaust grooves being connected through notches, the oil tank having an air outlet and an air inlet communicating with the interior of the atomizing core outer part at the top and bottom respectively, and exhaust holes communicating with the notches being disposed on both sides of the air outlet.

[0007] Furthermore, the multiple notches are not located on the same straight line. This increases the distance the gas travels through the exhaust channels, and the multiple exhaust channels connected to form a spiral shape can minimize the overflow of e-liquid from the oil tank.

[0008] Furthermore, the atomizer core outer component includes a mounting portion and connecting portions integrally formed at both ends of the mounting portion. The connecting portions are used to connect with the air inlet and the air outlet. The exhaust pipe is sleeved on the connecting portion located at the top of the atomizer core outer component. When the distance between the connecting portion and the exhaust pipe sleeve is close enough, most of the e-liquid contact gaps can be blocked, preventing e-liquid leakage.

[0009] Furthermore, the oil tank includes a middle shell and a base, with the vent located at the top of the middle shell and the vent located at the base.

[0010] According to a second aspect of this disclosure, an electronic cigarette is disclosed, including the above-mentioned oil tank, and further including an oil bottle and a mouthpiece, wherein the oil bottle is located below the oil tank, the mouthpiece is located above the oil tank and communicates with the air outlet and the exhaust port, and an oil inlet is provided at the bottom of the oil tank for inserting the oil bottle.

[0011] By adopting the above solution, the beneficial effects of this utility model are:

[0012] An exhaust pipe and exhaust sleeve are installed on the outer part of the atomizer core, so that excess gas in the oil tank can be discharged to the air outlet along the exhaust groove, avoiding over-pressure or under-pressure in the oil tank and improving the user experience.

[0021] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0022] like Figure 1-5 As shown, an oil tank 1 with a spiral exhaust structure includes an oil tank 1 body and an atomizing core assembly inside the oil tank 1. The atomizing core assembly includes an atomizing core outer part 11, an exhaust pipe 12 sleeved on the top of the atomizing core outer part 11, and an exhaust sleeve 13 sleeved on the outer surface of the exhaust pipe 12. The surface of the exhaust pipe 12 has multiple exhaust grooves 121, which are connected by a notch 122. The oil tank 1 has an air outlet 141 and an air inlet at the top and bottom, respectively, which are connected to the interior of the atomizing core outer part 11. Exhaust holes 142 that are connected to the notch 122 are provided on both sides of the air outlet 141.

[0023] The multiple notches 122 are not located on the same straight line. This can extend the distance that the gas needs to travel through the exhaust channel 121. The multiple exhaust channels 121 are connected to form a spiral shape, which minimizes the overflow of e-liquid in the oil tank 1.

[0024] The atomizer core outer component 11 includes a mounting portion 111 and connecting portions 112 integrally formed at both ends of the mounting portion 111. The connecting portions 112 are used to connect with the air outlet 141 and the air inlet. The exhaust pipe 12 is sleeved on the connecting portion 112 located at the top of the atomizer core outer component 11. When the distance between the connecting portion 112 and the exhaust pipe 12 is close enough, most of the e-liquid contact notch 122 can be blocked to prevent e-liquid leakage.

[0025] The oil tank 1 includes a middle shell 14 and a base 15. The air outlet 141 is located at the top of the middle shell 14, and the air inlet is located at the base 15.

[0026] like Figure 1-6 As shown in the figure, this utility model embodiment also provides an electronic cigarette, which includes as follows: Figure 1-5 The oil tank 1 shown also includes an oil bottle 2 and a cigarette holder 3. The oil bottle 2 is located below the oil tank 1, and the cigarette holder 3 is located above the oil tank 1 and is connected to the air outlet 141 and the exhaust port 142. The bottom of the oil tank 1 is provided with an oil inlet 16 for inserting the oil bottle 2.

[0027] Working principle: When there is excess gas inside the oil tank 1, it enters the notch 122 along the space between the mounting part 111 and the exhaust pipe 12. Since the exhaust sleeve 13 is tightly attached to the exhaust pipe 12, each exhaust channel 121 is connected along its respective notch 122. This means that the gas must pass through each section of the exhaust channel 121 before it can be discharged in the final notch 122, causing the gas to be discharged in a spiral pattern and enter the exhaust port 142. Since the exhaust port 142 is connected to the suction nozzle, the exhaust and pressure relief are completed. Similarly, when the oil tank 1 is under-pressured, external gas enters the oil tank 1 along the exhaust channel 121.

[0028] Due to the multi-stage exhaust channels 121 and the notch 122, the e-liquid in the oil tank 1 will not easily overflow from the exhaust channels 121, thus avoiding the risk of oil leakage.

[0029] This invention provides an exhaust pipe 12 and an exhaust sleeve 13 on the outer part 11 of the atomizing core, so that excess gas in the oil tank 1 can be discharged to the outside of the air outlet 141 along the exhaust groove 121, avoiding over-pressure or under-pressure in the oil tank 1 and improving the user experience.

[0030] Although this disclosure has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Because this disclosure can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
