Description

Technical Field

[0001] This application belongs to the field of electronic cigarette technology, and more specifically, relates to an electronic cigarette. Background Technology

[0002] With the rapid development of the e-cigarette market, consumer demand for products is becoming more diversified and personalized. Users are no longer satisfied with basic functional experiences, but are instead pursuing a wide variety of e-liquid flavors and flexibly adjustable nicotine concentrations.

[0003] However, e-cigarettes currently generally adopt a one-piece, non-separable structure, fixing the cartridge and battery module into a single unit, which limits users' freedom of choice in e-liquid selection. When users want to change flavors or adjust nicotine concentration, they are forced to replace the entire device, resulting in a large number of still functional battery modules being discarded along with the cartridge. This not only increases user costs but also causes resource waste and environmental pollution. Utility Model Content

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The present application will now describe an embodiment of an electronic cigarette (10). The electronic cigarette (10) may include a cartridge housing (100), a battery housing (200), an atomizing component (110), a battery component (210), a first connecting unit (120), and a second connecting unit (220). The atomizing component (110) is disposed inside the cartridge housing (100). The first connecting unit (120) is disposed on the surface of the cartridge housing (100) and electrically connected to the atomizing component (110). The battery component (210) is disposed inside the battery housing (200). The second connecting unit (220) is disposed on the surface of the battery housing (200) and electrically connected to the battery component (210). The first connecting unit (120) and the second connecting unit (220) cooperate to magnetically and detachably connect the cartridge housing (100) and the battery housing (200).

[0024] The beneficial effect of the electronic cigarette (10) provided in this application is that, compared with the prior art, the electronic cigarette (10) includes a cartridge compartment (100), a battery compartment (200), an atomizing component (110), a battery assembly (210), a first connecting unit (120), and a second connecting unit (220). The atomizing component (110) is disposed inside the cartridge compartment (100), the first connecting unit (120) is disposed on the surface of the cartridge compartment (100) and electrically connected to the atomizing component (110), and the battery assembly (210) is disposed on the surface of the cartridge compartment (100). Inside the battery compartment (200), a second connecting unit (220) is disposed on the surface of the battery compartment (200) and electrically connected to the battery assembly (210). The first connecting unit (120) and the second connecting unit (220) cooperate to magnetically and detachably connect the cartridge compartment (100) and the battery compartment (200). Thus, the atomizing assembly (110) is disposed inside the cartridge compartment (100), and the first connecting unit (120) is disposed on the surface of the cartridge compartment (100) and electrically connected to the atomizing assembly (110), so that the cartridge compartment... The battery compartment (200) is an independent atomizing module. The battery assembly (210) is located inside the battery compartment (200), and the second connecting unit (220) is located on the surface of the battery compartment (200) and electrically connected to the battery assembly (210), making the battery compartment an independent power supply module. The first connecting unit (120) and the second connecting unit (220) cooperate to magnetically and detachably connect the cartridge compartment (100) and the battery compartment (200), making the cartridge compartment (100) and the battery compartment (200) two separate independent modules. When users wish to change the e-liquid flavor or adjust the nicotine concentration, they only need to magnetically separate the cartridge (100) from the battery compartment (200) and replace it with a new cartridge (100) without having to replace the battery compartment (200). This not only greatly expands the user's freedom of choice in e-liquid and meets diversified and personalized needs, but also avoids the problem of the functional battery module being discarded along with the cartridge in the traditional integrated structure. As a result, it can not only reduce the long-term cost for users, but also reduce resource waste and environmental pollution.

[0025] Please refer to the following: Figure 4 and Figure 5 The battery compartment (200) is provided with a plug-in groove (230). The second connecting unit (220) is located at the bottom of the plug-in groove (230). The cartridge compartment (100) is partially inserted into the plug-in groove (230). The first connecting unit (120) is located at one end of the cartridge compartment (100) facing the plug-in groove (230). When the cartridge compartment (100) is inserted into the plug-in groove (230), the first connecting unit (120) and the second connecting unit (220) can automatically align and achieve magnetic connection, which can not only improve the assembly accuracy, but also enhance the connection stability.

[0026] Furthermore, the portion of the cartridge body (100) extending out of the insertion groove (230) has an arc-shaped profile, and its outer diameter gradually decreases along the direction away from the battery compartment (200). The aerosol outlet (130) of the electronic cigarette is formed at one end of the cartridge body (100) opposite to the insertion groove (230). The arc-shaped profile of the portion of the cartridge body (100) extending out of the insertion groove (230) and the gradual decrease in outer diameter along the direction away from the battery compartment (200) facilitates contact with the user's mouth, thereby improving comfort and convenience.

[0027] In this embodiment, the first connection unit (120) includes a first electrode (121), which is disposed on the side of the cartridge body (100) facing the insertion groove (230) and electrically connected to the atomizing component (110). The second connection unit (220) includes a second electrode (221) and a first magnetic element (222) disposed adjacent to the second electrode (221). The second electrode (221) and the first magnetic element (222) are disposed on the surface of the insertion groove (230) and electrically connected to the battery component (210). The first magnetic element (222) and the first electrode (121) are magnetically attracted to each other for detachably connecting the cartridge body (100) and the battery body (200) and forming an electrical connection between the first electrode (121) and the second electrode (221). The first magnetic component (222) and the first electrode (121) are magnetically attracted to each other, so that when the user brings the cartridge (100) close to the insertion groove (230) of the battery compartment (200), the magnetic force automatically guides the two compartments to be precisely aligned and quickly attracted and fixed. This not only provides convenience when connecting, but also provides appropriate resistance for separating the cartridge (100) and the battery compartment (200). In addition, the first magnetic component (222) and the second electrode (221) are arranged adjacent to each other, which can optimize the utilization rate of the bottom of the insertion groove (230), making the product structure compact and facilitating the miniaturization design of the product.

[0028] In the above embodiment, the side of the cartridge body (100) facing the insertion groove (230) is provided with an electrode groove (123), a first electrode (121) is disposed in the electrode groove (123), the surface of the insertion groove (230) is provided with a magnetic groove (233), a second electrode (221) and a first magnetic element (222) are disposed in the magnetic groove (233), and the first magnetic element (222) surrounds the outside of the second electrode (221), and the end of the second electrode (221) facing away from the cartridge body (100) extends out of the first magnetic element (222) along the magnetic groove (233).

[0029] It should be noted that the first electrode (121) is made of stainless iron. On the one hand, the first electrode (121) can complete the power transmission with the second electrode (221); on the other hand, the first electrode can directly form a magnetic adsorption relationship with the first magnetic component (222). That is, while the first electrode (121) is a conductive element, it also becomes part of the magnetic connection structure. This can realize the functional reuse of components. There is no need to set up an independent magnetic component on the cartridge body (100). This can simplify the internal structure of the body, reduce the complexity of parts and assembly costs, and provide more space for product miniaturization design. Furthermore, the battery body (200) can also include a printed circuit board. The printed circuit board is fixedly set inside the battery body (200), and the printed circuit board is electrically connected to the second electrode (221) and the battery assembly (210) respectively.

[0030] In another embodiment, the first connecting unit (120) includes a third electrode and a second magnetic element disposed adjacent to the third electrode. The third electrode and the second magnetic element are disposed on the side of the cartridge housing (100) facing the insertion groove (230) and electrically connected to the atomizing assembly (110). The second connecting unit (220) includes a fourth electrode. The fourth electrode is disposed on the surface of the insertion groove (230) and electrically connected to the battery assembly (210). The second magnetic element and the fourth electrode are magnetically attracted to each other for detachably connecting the cartridge housing (100) and the battery housing (200) and forming an electrical connection between the third electrode and the fourth electrode.

[0031] In the above embodiments, the side of the cartridge housing (100) facing the insertion groove (230) is provided with a magnetic groove, the third electrode and the fourth magnetic element are disposed in the magnetic groove, and the second magnetic element surrounds the outside of the third electrode. The surface of the insertion groove (230) is provided with an electrode groove, and the fourth electrode is disposed in the electrode groove. Furthermore, the battery housing (200) may also include a printed circuit board, which is fixedly disposed inside the battery housing (200) and electrically connected to the third electrode and the battery assembly (210) respectively.

[0032] In this embodiment, the inside of the cartridge body (100) is provided with an oil storage chamber (140), and the atomizing component (110) is disposed in the oil storage chamber (140). The cartridge body (100) has an aerosol channel (150). The aerosol channel (150) forms an aerosol outlet (130) at one end facing away from the bottom of the insertion groove (230). The atomizing component (110) is connected to the oil passage of the oil storage chamber (140) and to the air passage of the aerosol channel (150).

[0033] Please see Figure 6The aerosol channel (150) includes a cylindrical section and a conical section. The cartridge housing (100), cylindrical section, and conical section are integrally formed. The aerosol channel (150) has a cylindrical section adjacent to the atomizing component (110) and a conical section away from the atomizing component (110). The inner diameter of the conical section gradually increases in the direction away from the cylindrical section, and an aerosol outlet (130) is formed on the surface of the cartridge housing (100). On the one hand, the cylindrical section of the aerosol channel (150) allows aerosol to enter the conical section from the atomizing component (110). As the cross-sectional area of ​​the aerosol gradually increases from the cylindrical section to the conical section, it slows down and diffuses, reducing airflow resistance during inhalation, making the inhalation process easier and smoother, and improving the comfort of use. On the other hand, the gradually expanding structure also makes the curvature change of the inner wall of the channel gentle, avoiding right angle or sharp bend design, which can reduce the phenomenon of condensation of aerosol due to impact with the inner wall of the channel.

[0034] Please refer to the following: Figure 6 and Figure 7 The atomizing assembly (110) includes an outer atomizing tube (111), an inner atomizing tube (112), absorbent cotton (not shown in the figure), outer wrapping cotton (113), and a heating wire assembly (not shown in the figure). The inner atomizing tube (112) is fixedly installed on the bottom of the cartridge body (100). One end of the outer atomizing tube (111) is fixedly connected to the aerosol channel (150), and the other end of the outer atomizing tube (111) is sleeved on the inner atomizing tube (112). The outer atomizing tube (111) and the atomizing... An annular gap is formed between the inner tubes (112). The outer cotton (113) is placed in the annular gap between the atomizing outer tube (111) and the atomizing inner tube (112). The sleeved portions of the atomizing inner tube (112) and the atomizing outer tube (111) are respectively provided with at least one oil inlet hole along the circumferential direction, so that the oil storage chamber (140) is connected to the annular gap. The oil-absorbing cotton (not shown in the figure) is placed inside the atomizing inner tube (112) and contacts the outer cotton (113) through the oil inlet hole. The outer cotton (113) locks and controls the e-liquid through capillary action, so that it can continuously supply oil to the oil-absorbing cotton (not shown in the figure) and effectively prevent the uncontrolled leakage of liquid e-liquid when not in operation. At the same time, the oil-absorbing cotton (not shown in the figure) placed inside the atomizing inner tube (112) contacts the outer cotton (113) through the oil inlet hole, forming a two-stage oil supply system. The oil-absorbing cotton (not shown in the figure) precisely absorbs the required amount of oil from the outer cotton (113), ensuring that the amount of oil directly surrounding the heating wire assembly (not shown in the figure) is always moderate and uniform. This can avoid the "dry burning" phenomenon caused by insufficient oil supply, and also eliminate the risk of "leakage" caused by excessive oil supply, thereby improving the reliability and safety of atomization.

[0035] In this embodiment, the cartridge housing (100) may include a sealing plug (114), which is disposed inside the cartridge housing (100) and encloses the cartridge housing (100) to form an oil storage chamber (140), and the atomizing inner tube (112) is fixedly disposed on the sealing plug (114).

[0036] In this embodiment, the cartridge housing (100) may further include sealing cotton (115), which is disposed between the cartridge housing (100) and the sealing plug (114).

[0037] In this embodiment, the outer wall of the e-cigarette cartridge (100) is provided with a limiting countersunk hole and an e-liquid filling hole. The e-cigarette cartridge (100) may also include an e-liquid filling cap and a limiting plug fixedly disposed on the e-liquid filling cap. The e-liquid filling cap is tightly fitted to the outer wall of the e-cigarette cartridge (100), and the limiting plug is correspondingly inserted into the limiting countersunk hole. When the e-liquid is exhausted, the user does not need to discard the entire e-cigarette cartridge; they only need to inject e-liquid through the e-liquid filling hole to continue using it, which can extend the service life of the e-cigarette and reduce the user's usage cost.

[0038] Further, please refer to Figure 7 The cartridge housing (100) may include a cartridge shell (101) and a cartridge base (102). A sealing plug (114) is disposed on the cartridge base (102) and encloses the cartridge housing (100) to form an oil storage chamber (140). An atomizing inner tube (112) is fixedly disposed on the sealing plug (114), and a sealing cotton (115) is disposed between the cartridge base (102) and the sealing plug (114).

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
