[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0049] According to one embodiment of the present invention, referring to Figures 1 to 7 An electronic cigarette includes a cigarette rod 1 and a cigarette cartridge 2. The cigarette rod 1 is provided with an interface 3, and the cigarette cartridge 2 is provided with a plug 4. When the interface 3 is configured to be connected to the plug 4 of the cigarette cartridge 2, the cigarette cartridge 2 is powered, and when the interface 3 is configured to be connected to the charging head, the cigarette rod 1 is charged. Different from the prior art, the utility model combines the charging interface and the cigarette cartridge interface originally provided on the cigarette rod 1 into one. When the electronic cigarette is in use, the interface 3 is combined with the plug 4 on the cigarette cartridge 2, so that the cigarette rod 1 is in a closed state, and the outer surface of the cigarette rod 1 does not need a separate charging interface.

[0050] Furthermore, the interface 3 of the electronic cigarette of the utility model is always in a state of being combined with the cigarette cartridge 2 or the charging head, which can avoid the accumulation of debris and dust inside it, and also avoid the charging heating phenomenon caused by the connection of debris and dust at the charging port, further improving the safety performance of the electronic cigarette, and at the same time can effectively extend the service life of the electronic cigarette.

[0051] Furthermore, by combining the charging port and the two ports of the cigarette cartridge into one, the number of holes opened on the outer surface of the cigarette rod 1 is reduced. While improving the dustproof performance of the electronic cigarette, the process steps of opening holes on the surface of the cigarette rod 1 are reduced, the overall production process of the electronic cigarette is optimized, and the process steps are simplified. For the production of electronic cigarettes, it can significantly improve production efficiency and reduce production costs. Compared with the existing technology, it has outstanding substantive characteristics and significant progress.

[0052] According to an embodiment of the utility model, the interface 3 on the cigarette rod 1 is a USB interface, and the plug 4 on the cigarette cartridge 2 is a USB plug.

[0053] like Figure 6 As shown, the USB plug on the cigarette cartridge 2 has four contacts, including a GND pin, a VCC pin and two interconnected pins. The two interconnected pins are short-circuit points. The short-circuit points allow the cigarette rod 1 to identify whether the cigarette cartridge 2 is connected. Figure 7 As shown, the USB interface on the cigarette rod 1 has four contacts, including a GND pin, a VCC pin and two MCU pins. When the USB plug on the cigarette cartridge 2 is inserted, the two MCU pins are connected through the short-circuit point of the USB plug. At this time, the microprocessor unit (MCU) works and recognizes that the current power supply mode is in progress. When the cigarette rod 1 is connected to the charging head, since the two MCU pins are not connected, the cigarette rod 1 is in the charging state. Since the MCU control battery of the utility model will only supply power when the cigarette cartridge is connected, if the cigarette cartridge is not connected, it will not supply power, and it can also protect the battery from the impact of the VCC and GND short circuit, so it is safer to use.

[0054] In this embodiment, the interface 3 on the cigarette rod 1 is a USB interface, and the plug 4 on the cigarette cartridge 2 is a USB plug. On the one hand, due to the mature manufacturing process of this connection form, the stability of the use of the electronic cigarette can be ensured, and the user can quickly find a suitable charging device.

[0055] According to an embodiment of the utility model, further, the interface 3 on the cigarette rod 1 is a USB Type-C interface, and the plug 4 on the cigarette cartridge 2 is a USB Type-C plug. The USB Type-C interface is a universal charging port for current mobile phones and some computers, which provides convenience for charging the electronic cigarette. By setting the plug 4 on the cigarette cartridge 2 as a USB Type-C plug, it can be combined with devices other than the cigarette rod 1. As long as the USB Type-C interfaces corresponding to these devices can discharge to the outside, the cigarette cartridge 2 of the utility model can be combined with them to draw power and use the device as a battery. Such as with a power bank, mobile phone or computer. This design can greatly improve the convenience of smoking this electronic cigarette.

[0056] According to an embodiment of the utility model, the electronic cigarette of the utility model is provided with one or more convex parts (as shown in the attached drawings) on one side of the cartridge 2 that is assembled and connected with the cigarette rod 1, and the cigarette rod 1 is provided with one or more corresponding concave parts (as shown in the attached drawings), and when the interface 3 on the cigarette rod 1 is configured to be connected with the plug 4 on the cartridge 2, the convex part is inserted into the concave part. By providing the convex part and the concave part, on the one hand, it is beneficial to the plug-in positioning when the cartridge 2 and the cigarette rod 1 are connected, and in addition, the cooperation of the convex part and the concave part can share the force that the plug 4 needs to bear when the electronic cigarette of the utility model is subjected to external force, such as the torsional moment or bending moment of the cartridge 2 relative to the cigarette rod 1, so as to prevent the plug 4 from being easily damaged (the specific structure of the above convex part and the concave part and the realization of their cooperation are common knowledge in the field, and therefore are not specifically shown in the attached drawings). Of course, the use of the convex part and the concave part structure here is not necessary.

[0057] In this embodiment, the convex part on the cigarette cartridge 2 is a positioning column, and the concave part on the cigarette rod 1 is a positioning hole, and there are two positioning holes, which are respectively arranged on both sides of the interface 3. The positioning column can be set to one or two, and the position of the one or two positioning columns matches the positioning hole. When the cigarette cartridge 2 is connected to the cigarette rod 1, the one or two positioning columns are inserted into the positioning hole to achieve positioning while ensuring the strength of the connection part between the cigarette cartridge 2 and the cigarette rod 1 (the specific structure of the above convex part and concave part itself and the realization of their matching are common knowledge in this field, so they are not specifically shown in the drawings).

[0058] According to an embodiment of the utility model, the electronic cigarette of the utility model, the cigarette cartridge 2 includes a mouthpiece 5, and the mouthpiece 5 is provided with an inhalation port for the user to inhale. The structure of the inhalation port itself is a prior art and will not be described again. The cigarette rod 1 is also provided with a mouthpiece slot 6. In order to further improve the integrity of the product and avoid the problem that the cigarette cartridge 2 needs to be placed or stored separately when the cigarette rod 1 is charged, which leads to easy loss or forgetting, in this embodiment, a mouthpiece slot 6 is provided on the cigarette rod 1. When the cigarette rod 1 is connected to the charging head for charging, the mouthpiece 5 of the cigarette cartridge 2 can be inserted into the mouthpiece slot 6 on the cigarette rod 1 to prevent the cigarette cartridge 2 from being lost or forgotten.

[0059] Furthermore, in the present embodiment, an ultraviolet lamp, also called a UV lamp, is provided inside the mouthpiece slot 6. During use, the cigarette cartridge 2 needs to contact the user's lips at the mouthpiece 5 outlet, which is usually relatively moist and easy to breed bacteria. In order to further improve the hygiene of the electronic cigarette of the present invention, the mouthpiece 5 can be disinfected by providing an ultraviolet lamp inside the mouthpiece slot 6. The ultraviolet lamp is configured to emit light with a wavelength in the range of 100-280nm, preferably in the range of 200-280nm. Light in the above wavelength range can effectively kill microorganisms such as bacteria and viruses. According to common sense, the UV lamp can be various types of lamps, and LED lamps are preferred in the present invention.

[0060] In the present embodiment, two or more separately arranged inhalation ports are arranged on different sides of the cigarette cartridge 2 or at different positions on the same side. For example, two inhalation ports can be provided, so that the smoke inhaled by the electronic cigarette device can be dispersed in the user's mouth, rather than allowing the concentrated hot smoke to be directly guided to a certain point on the upper palate of the user, which can improve the discomfort caused by long-term smoking at a certain point in the mouth.

[0061] According to one embodiment of the utility model, the cigarette rod 1 includes a flexible shell 7 and a battery 8 arranged inside the flexible shell 7, and the battery 8 is connected to the interface 3 through a circuit board 9.

When the mouthpiece slot 6 on the cigarette rod 1 is set at the bottom of the cigarette rod 1, the mouthpiece 5 of the cigarette bomb 2 is inserted into the mouthpiece slot 6 at the bottom of the cigarette rod 1 by bending the cigarette rod 1. In a preferred manner, the entire electronic cigarette can be formed into a ring shape, so that the user can carry and find it conveniently, for example, it can be used as a bracelet on the wrist. The flexible shell 7 can be set in a way that all areas can be flexibly folded, or it can be set in a way that some areas cannot be flexibly folded, as long as it does not affect the overall flexible bending, especially to ensure that the mouthpiece 5 can be smoothly inserted into the mouthpiece slot 6.

[0062] In this embodiment, the flexible shell 7 can be made of elastic material, which can play a certain role in buffering and protection, and can give the product a better feel. Optionally, in this embodiment, the flexible shell 7 is a rubber shell, because the rubber shell, in addition to having the characteristics of good feel and good buffering effect, also has good airtightness, which can further improve the dustproof performance of the electronic cigarette of the utility model.

[0063] Optionally, the battery 8 can be a general battery arranged in a small area, which will not affect the flexibility of the flexible shell. The battery 8 can also be a flexible battery formed by a plurality of small batteries connected in a flexible manner. The plurality of small batteries with smaller volumes are connected by connecting wires and distributed inside the flexible shell 7, so that the electronic cigarette is flexible as a whole and can be bent and deformed. The battery 8 can also be a battery that is flexible as a whole and is made of flexible materials. It has a certain flexibility itself, such as a flexible battery made of nanomaterials and organic materials in the prior art.

[0064] In this embodiment, the circuit board 9 is arranged inside the flexible housing 7, and the circuit board 9 is electrically connected to the battery 8. Preferably, the circuit board 9 can be a flexible circuit board FPC to further improve the flexibility of the electronic cigarette of the utility model. A flexible printed circuit board (FPC for short) is a flexible printed circuit board made of polyimide or polyester film as a substrate.

[0065] According to an embodiment of the utility model, in an electronic cigarette using smoke oil, the smoke cartridge 2 of the electronic cigarette includes a smoke oil box 10 connected to the cigarette holder 5 and a heater for heating the smoke oil, the smoke oil box 10 and the heater are arranged between the plug 4 and the cigarette holder 5, and the heater is arranged close to the cigarette holder 5 for heating the atomized smoke oil. In order to further improve the overall flexibility of the electronic cigarette, in this embodiment, the shell of the smoke cartridge 2 can also be a flexible material (such as a rubber shell or a plastic material), and the smoke oil box 10 can also be a flexible liquid container (such as a rubber or plastic material).

[0066] According to one embodiment of the utility model, an LED indicator light (such as the attached Figure 1 The LED indicator light is electrically connected to the circuit board 9. Further, the LED indicator light can indicate different states by displaying different colors, such as red, green and purple, respectively, where red represents low power state, green represents inhalation or sufficient power state, and purple represents disinfection state.

[0067] According to an embodiment of the utility model, this embodiment provides a cigarette rod 1, which is provided with an interface 3. When the interface 3 is configured to be connected to the cigarette cartridge 2, it is used to power the cigarette cartridge 2. When the interface 3 is configured to be connected to the charging head, it is used to charge the cigarette rod 1. The interface 3 is a USB Type-C interface. The cigarette rod 1 is provided with a positioning hole (not shown in the accompanying drawings) that matches the cigarette cartridge 2. There are two positioning holes, which are respectively arranged on both sides of the interface 3. A cigarette holder slot 6 is also provided at the bottom of the cigarette rod 1. The interior of the cigarette holder slot 6 is provided with an LED lamp that can emit ultraviolet rays, which can disinfect the cigarette holder 5.

[0068] According to an embodiment of the utility model, a cigarette cartridge 2 is provided, and a plug 4 is provided on the cigarette cartridge 2. The plug is a USB plug, and preferably, the plug 4 is a USB Type-C plug. The cigarette cartridge 2 cooperates with the cigarette rod 1 to form the electronic cigarette of the utility model.

[0069] Since the USB plug is highly universal, by setting the plug 4 on the cartridge 2 as a USB plug, it can also be combined with devices with USB interfaces other than the cigarette rod 1. As long as the USB interfaces corresponding to these devices can discharge externally, the cartridge 2 of the utility model can be combined with them. For example, with a power bank, a mobile phone or a computer. When the battery on the cigarette rod 1 is out of power and cannot temporarily power the cartridge 2, the user can power the cartridge 2 through a power bank, a mobile phone or a computer with a USB interface, which facilitates the smoking of the electronic cigarette at any time and greatly improves its convenience of use.

[0070] The structures themselves, manufacturing methods and specific working methods of the heater, circuit board, housing, battery, e-liquid box, liquid container, LED indicator light, ultraviolet lamp, cigarette holder and the like in the utility model are all prior arts in the field and will not be further elaborated here.

[0071] According to one embodiment of the utility model, as a pair Figure 1 A simple alternative to the embodiment shown is Figure 8 As shown, this embodiment provides an electronic cigarette, including a cigarette rod 1 and a cigarette cartridge 2, a plug 4 is arranged on the cigarette rod 1, an interface 3 is arranged on the cigarette cartridge 2, and the plug 4 is configured to supply power to the cigarette cartridge 2 when connected to the interface 3 of the cigarette cartridge 2, and the plug 4 is configured to charge the cigarette rod 1 when connected to an external charging port.
