[0034] Reference below Figures 1-4 The mixed-flavor electronic cigarette according to an embodiment of the present invention is described.

[0035] like Figures 1-4 As shown, the mixed-flavor electronic cigarette includes a shell 100. The shell 100 adopts a hollow structure in the middle. From top to bottom, a suction nozzle 110, an oil storage chamber 120 and a drive assembly 130 are sequentially arranged. The drive assembly 130 includes a power supply assembly, a control panel and a vent and other structures. The drive assembly 130 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0036] The device also includes at least two sets of oil cartridges 210 and an atomizer assembly. Specifically, in this embodiment, two sets of oil cartridges 210 are provided, and the number of oil cartridges 210 is adjusted based on the desired flavor mix. The oil cartridges 210 are installed within the oil storage chamber 120 and surround the atomizer passage 140. Oil guide holes 211 are provided on the sidewalls of the oil cartridges 210 near the atomizer passage 140.

[0037] The atomization assembly is arranged in the atomization channel 140, and the atomization assembly includes a heating net 310, an oil-conducting medium 320 and an oil-conducting valve body 330. The oil-conducting medium 320 wraps the outer ring of the heating net 310, and the middle part of the heating net 310 is hollowed out in a cylindrical shape. The oil at the heating net 310 is heated to form oil mist and is transported to the nozzle 110 through the atomization channel 140. The heating net 310 and the oil-conducting medium 320 are technical solutions well known to those skilled in the art and will not be described in detail in this embodiment. The oil-conducting valve body 330 is arranged to wrap the oil-conducting medium 320, and the oil-conducting holes 211 of each oil-liquid cigarette cartridge 210 are respectively connected to the oil-conducting valve body 330. The oil-conducting valve body 330 is used to transport the oil in the oil-liquid cigarette cartridge 210 to the oil-conducting medium 320.

[0038] Among them, the oil guide valve body 330 is provided with an oil guide channel 331, one end of the oil guide channel 331 is provided with a liquid outlet hole 333 connected to the oil guide medium 320, and the other end is provided with two liquid inlet holes 332, the two liquid inlet holes 332 are respectively connected to the oil guide holes 211 of the adjacent oil and liquid cartridge 210, and the oil guide channel 331 adopts a Tesla valve structure.

[0039] Specifically, the oils in the two oil-liquid cigarette cartridges 210 enter the oil guide channel 331 from the corresponding liquid inlet holes 332 respectively, and the mixing of the two oils is achieved by utilizing the characteristics of the Tesla valve structure of the oil guide channel 331. The Tesla valve utilizes the inertia of the fluid and a fixed geometric structure to achieve liquid mixing and guided flow control without the need for any moving parts or external energy input. When the fluid passes through the Tesla valve in the forward direction, it will be accelerated in the specifically designed path inside the valve, so that the liquid in the channel is fully mixed. When flowing in the reverse direction, due to the extremely large fluid resistance caused by the path design, the two liquids can also be mixed but the flow rate is reduced. The one-way circulation effect of the Tesla valve is affected by the external pressure and the width of the internal channel. By adjusting the width of the oil guide channel 331 and coordinating its structure, it is possible to achieve small and large flow electronic atomizers for multi-flavor oil mixing and inhalation.

[0040] The oil guide valve body 330 itself has a simple structure and no moving parts, which greatly improves the operational stability of the structure, ensures the inhalation effect of the electronic atomizer, and enhances the user experience.

[0041] In some embodiments of the present invention, the oil guide valve body 330 adopts a plate structure, and the oil guide channel 331 , the liquid inlet hole 332 and the liquid outlet hole 333 are punched out of the surface of the oil guide valve body 330 and then wound to form a cylindrical structure.

[0042] Specifically, the oil guide valve body 330 is formed into the oil guide channel 331 by stamping and then rolled into a cylindrical shape. The processing method is simple and fast, with a high yield rate, and can meet the rapid production of different channel designs.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the areas on both sides of the oil guide valve body 330 corresponding to the oil guide channel 331 are covered with cover plates (not shown in the drawings), the liquid outlet 333 is connected to the oil guide medium 320, and the liquid inlet 332 is connected to the oil guide hole 211.

[0044] Specifically, after both sides of the oil guide valve body 330 are covered by the cover plate, the cross section of the oil guide channel 331 forms a complete and closed channel surface, and the oil enters the oil guide channel 331 through the liquid inlet hole 332 and then enters the oil guide medium 320 through the liquid outlet hole 333.

[0045] In some embodiments of the present invention, Figure 2 As shown, the oil guide channel 331 is provided with a main line 331a and a return line 331b distributed on both sides of the main line 331a. The two ends of the main line 331a are respectively connected to the liquid outlet 333 and the liquid inlet 332. The return line 331b is connected to the main line 331a, and the end of the return line 331b is folded back to form a U-shaped return port 331c.

[0046] Specifically, the return lines 331b on both sides of the main line 331a are staggered, and the U-shaped return port 331c at the end of the return line 331b can make the liquid flow direction of the return line 331b and the liquid flow direction of the main line 331a in the opposite direction, so that the two liquids collide and are fully mixed.

[0047] Further, if Figure 2 As shown, one liquid inlet 332 is connected to the return line 331b, and the other liquid inlet 332 is connected to the main line 331a. To allow the oil from the two groups of oil cartridges 210 to mix within the oil guide channel 331, the two liquid inlets 332 are connected to the oil guide holes 211 of the two groups of oil cartridges 210, respectively. The two oils enter the channel from the main line 331a and the return line 331b respectively, and the two oils mix at the confluence.

[0048] In other embodiments, three groups of oil cartridges 210 may be provided. These three groups of oil can then be combined and mixed through different return lines 331b or main lines 331a. The present invention does not elaborate on the number of oil cartridges 210 provided and the structure of the oil-conducting channels 331 connecting them. It should be understood that any changes in the number of oil cartridges 210 provided and the structure of the oil-conducting channels 331 connecting them, without departing from the basic concept of the present invention, are considered to be within the scope of protection defined by the present invention.

[0049] Furthermore, the channel width of the return line 331b is no greater than the channel width of the main line 331a. This serves to increase the flow rate of the oil in the oil-conducting channel 331 during reverse flow. When a user inhales forcefully, creating a negative pressure in the atomizing channel 140, the oil can be discharged slowly even when the oil-conducting valve body 330 is used in reverse, preventing the Tesla valve's excessive backflow prevention effect from affecting the oil's entry into the oil-conducting medium 320.

[0050] In some embodiments of the present invention, Figure 2 As shown, the main line 331a is tilted on the oil guide valve body 330. Specifically, due to the small size of the electronic atomizer and the limited space of the internal atomization component, the inclined setting of the main line 331a can effectively extend the channel length of the main line 331a, thereby improving the mixing time and mixing effect of the oil.

[0051] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a foolproof groove 334 is provided on the top of the oil guide valve body 330, and a foolproof protrusion 101 is provided at the corresponding position of the shell 100. The foolproof groove 334 and the foolproof protrusion 101 are engaged and connected to prevent the atomizer assembly from being installed misplaced.

[0052] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, two semicircular cavities are formed in the oil storage chamber 120 for installing two oil cartridges 210.

[0053] In some embodiments of the present invention, the oil guide valve body 330 is connected to the oil guide medium 320 in a positive or negative manner. Specifically, when the oil guide valve body 330 is in a positive manner, the oil guide speed of the oil guide channel 331 is improved, which is suitable for electronic atomizers with large flow rates. Figure 2 As shown, when the oil guide valve body 330 is inverted, the oil guide speed of the oil guide channel 331 is reduced, which is suitable for electronic atomizers with small flow rates, meeting the needs of electronic atomizers of different powers and having wider applicability.
