[0061] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0062] See also Figures 1 to 10 The utility model provides a cigarette cartridge 130, a cigarette rod 110 and an electronic cigarette. The cigarette cartridge 130 and the cigarette rod 110 can be separated or connected, that is, the cigarette cartridge 130 can be detachably connected to the cigarette rod 110. The cigarette cartridge 130 can usually be replaced by a new cigarette cartridge 130 after it has been used and loses its corresponding function. The cigarette cartridge 130 and the cigarette rod 110 are assembled into an electronic cigarette.

[0063] like Figures 1 to 10As shown, the electronic cigarette according to the utility model may include a cigarette rod 110 and a cigarette cartridge 130. The cigarette rod 110 may include a shell 111. A water flow channel 111b and a smoke oil flow channel 111c are formed inside the shell 111. The connecting end of the shell 111 is provided with a first connecting hole 111g, a second connecting hole 111i and a confluence hole 111d. The first connecting hole 111g is connected to one end of the water flow channel 111b. The second connecting hole 111i is connected to one end of the smoke oil flow channel 111c. The confluence hole 111d is connected to the other end of the water flow channel 111b and the other end of the smoke oil flow channel 111c. The cigarette cartridge 130 is connected to the connecting end of the shell 111. The cigarette cartridge 130 may include a water containing chamber 131, a smoke oil containing chamber 132 and a smoke flow channel 133 that are independent of each other. The water containing chamber 131 is connected to the first connecting hole 111g. The smoke oil containing chamber 132 is connected to the second connecting hole 111i. The smoke flow channel 133 is connected to the confluence hole 111d. Among them, the water flow channel 111b is a Tesla valve channel set in the opposite direction in the direction from the first connection hole 111g to the confluence hole 111d. It can be understood here that the resistance of the water flow channel 111b to the liquid in the direction from the first connection hole 111g to the confluence hole 111d is greater than the resistance to the liquid in the direction from the confluence hole 111d g to the first connection hole 111. The smoke oil flow channel 111c is a Tesla valve channel set in the opposite direction in the direction from the second connection hole 111i to the confluence hole 111d. It can be understood here that the resistance of the smoke oil flow channel 111c to the liquid in the direction from the second connection hole 111i to the confluence hole 111d is greater than the resistance to the liquid in the direction from the confluence hole 111d to the second connection hole 111i.

[0064] According to the cigarette cartridge 130 of the utility model, there are a water containing chamber 131, a smoke oil containing chamber 132 and a smoke flow channel 133 which are isolated from each other. When connected to the cigarette rod 110, the water containing chamber 131 is connected to the water flow channel 111b of the cigarette rod 110 to supply water to the cigarette rod 110, and the smoke oil containing chamber 132 is connected to the smoke oil flow channel 111c of the cigarette rod 110 to supply smoke oil to the cigarette rod 110. The water and the smoke are atomized by the cigarette rod 110 and then transported through the smoke flow channel 133. The user can smoke a mixture of the smoke oil mist and the water mist through the smoke flow channel 133. By adopting the above means, it is possible to replace part of the smoke of the electronic cigarette with water mist in the application state, and even increase the amount of the mist. That is, compared with the traditional electronic cigarette, the same amount of smoke contains less atomized substances of the smoke oil, which helps to reduce the harm to the health of the user while satisfying the user's experience.

[0065] According to the cigarette rod 110 of the utility model, by setting the water flow channel 111b located between the first connecting hole 111g and the confluence hole 111d as a reverse Tesla valve channel, and setting the smoke oil flow channel 111c located between the second connecting hole 111i and the confluence hole 111d as a reverse Tesla valve channel, the resistance of the liquid in the cigarette cartridge 130 to flow toward the confluence hole 111d can be increased, thereby effectively preventing the liquid in the cigarette cartridge 130 from flowing out due to factors such as the cigarette cartridge 130 being shaken or tipped over when the cigarette cartridge 130 is connected.

[0066] According to the electronic cigarette of the present invention, by setting the water flow channel 111b located between the first connecting hole 111g and the confluence hole 111d as a reverse Tesla valve channel, and setting the smoke oil flow channel 111c located between the second connecting hole 111i and the confluence hole 111d as a reverse Tesla valve channel, the resistance of the liquid in the smoke cartridge 130 to flow toward the confluence hole 111d can be increased, thereby effectively preventing the liquid in the smoke cartridge 130 from flowing out due to shaking.

[0067] See also Figures 1 to 8 In addition, the cigarette rod 110 may also include a circuit board 112, a heating element and a smoke generator 115. The circuit board 112 may include a main circuit board 112a and a sub-circuit board 112b. The main circuit board 112a is arranged in the inner cavity 111a of the shell 111. The sub-circuit board 112b passes through the confluence hole 111d and extends to the outside of the shell 111. And the sub-circuit board 112b is clearance-matched with the confluence hole 111d. The heating element is electrically connected to the sub-circuit board 112b. The smoke generator 115 is connected to the confluence hole 111d and enclosed with the shell 111 to form a chamber. The chamber accommodates the heating element and the sub-circuit board 112b. Here, because the sub-circuit board 112b is clearance-matched with the confluence hole 111d, water and smoke oil can flow into the chamber from the gap between the sub-circuit board 112b and the confluence hole 111d. The heating element can heat the liquid flowing into the chamber to evaporate the liquid, and then the evaporated smoke oil and water pass through the smoke generator 115 to form a water-oil mixed smoke.

[0068] See also Figures 1 to 4, for example, along the spacing direction of the water flow channel 111b and the smoke oil flow channel 111c. The opposite sides of the auxiliary circuit board 112b are spaced apart from the hole wall of the confluence hole 111d. This can balance the length of the path of the smoke oil and water flowing to the chamber. The cigarette rod 110 may include two heating elements. The two heating elements are respectively recorded as a first heating element 113 and a second heating element 114. The first heating element 113 is electrically connected to a portion of the auxiliary circuit board 112b close to the water flow channel 111b. The second heating element 114 is electrically connected to a portion of the auxiliary circuit board 112b close to the smoke oil flow channel 111c. By providing two heating elements, the first heating element 113 and the second heating element 114, the time gap between the water and the smoke oil being heated can be made smaller, thereby improving the uniformity of the water-oil mixed smoke.

[0069] For example, the heating element is a ceramic heating plate.

[0070] It can be understood that in other embodiments, the heating element can be a heating element made of other materials.

[0071] See also Figures 1 to 7 In addition, the shell 111 may also include a via 111e. The via 111e is arranged at intervals from the confluence hole 111d along the hole depth direction of the confluence hole 111d. And the via 111e is closer to the inner cavity 111a of the shell 111 than the confluence hole 111d. The electronic cigarette may also include a sealing ring 117. The sealing ring 117 is sleeved on the outside of the auxiliary circuit board 112b. And the sealing ring 117 is sealed and connected between the main circuit board 112a and the via 111e. By setting the via 111e for passing the auxiliary circuit board 112b, the sealing ring 117 can be set to seal the gap between the main circuit board 112a and the via 111e, thereby preventing smoke oil and water from entering the interior of the cigarette rod 110 through the via 111e, thereby improving the safety of the circuit. Furthermore, the sealing ring 117 can seal the gap between the main circuit board 112a and the via hole 111e, thereby preventing smoke oil and water from entering the interior of the housing 111, thereby preventing the main circuit board 112a from being contaminated and rusted, thereby preventing malfunctions.

[0072] Optionally, the sealing ring 117 can be configured as a soft elastic rubber ring such as a sealing rubber ring.

[0073] See also Fig. 9 and Fig.10For example, the smoke flow channel 133 has a first end 133a and a second end 133b spaced along its own extension direction. The first end 133a of the smoke flow channel 133 is suitable for connecting to the confluence hole 111d. The second end 133b of the smoke flow channel 133 is suitable for approaching the user and serving as an end to be sucked by the user. The smoke flow channel 133 is a Tesla valve channel set in a positive direction in the direction from the first end 133a to the second end 133b. It can be understood here that the resistance of the smoke flow channel 133 to the smoke in the direction from the first end 133a to the second end 133b is less than the resistance to the smoke in the direction from the second end 133b to the first end 133a. By setting the smoke flow channel 133 as a positive Tesla valve channel, it is conducive to the mixed smoke of water mist and smoke oil mist generated at the smoke generator 115 to be discharged more smoothly, and can be gradually accelerated during the discharge process. After the smoker takes a puff, the mouthpiece of the electronic cigarette 100 can still keep releasing smoke for a certain period of time, which can better simulate the realism and atmosphere of smoking.

[0074] See also Figures 1 to 4 For example, the circuit board 112 may include a microcontroller (not shown). The microcontroller here may also be referred to as a microcontroller unit (MCU for short). The microcontroller is arranged on the main circuit board 112a. The main circuit board 112a also includes a power management circuit (not shown) to provide matching power to each device of the main circuit board 112a. The cigarette rod 110 may also include a detection device 116. The detection device 116 is connected to the end of the auxiliary circuit board 112b away from the main circuit board 112a. The heating element is located between the detection device 116 and the main circuit board 112a. The detection device 116 is electrically connected to the microcontroller. The detection device 116 is suitable for detecting the composition and content of the smoke oil output by the smoke oil flow channel 111c. By setting a detection device 116 in the cigarette rod 110 and setting the detection device 116 at the end of the auxiliary circuit board 112b away from the main circuit board 112a, the composition and content of the cigarette oil can be detected, so as to determine through the microcontroller whether the composition and content of the cigarette oil are consistent with the nominal composition and content of the cigarette oil, and then judge the authenticity of the cigarette oil to achieve the purpose of anti-counterfeiting.

[0075] Continue reading Figures 1 to 4 Optionally, the detection point of the detection device 116 is located on the same side of a heating element close to the smoke oil flow channel 111c. The smoke oil vapor detected by the detection device 116 is the smoke oil vapor before entering the smoke generator 115. The smoke oil components that the detection device 116 can detect may include nicotine, tar, propylene glycol, glycerol, etc.

[0076] Furthermore, the microcontroller is also connected to the heating element to control the working state of the heating element. For example, when the microcontroller determines that the smoke oil composition is qualified, the electric circuit where the heating element is located is controlled to be in a state that can be started. At this time, after the operator operates the start switch of the electronic cigarette 100, the heating element can be controlled to be powered on and work. When the microcontroller determines that the smoke oil composition is unqualified, the electric circuit where the heating element is located is controlled to be in a state that cannot be started. At this time, after the operator operates the start switch of the electronic cigarette 100, the heating element cannot be controlled to be powered on and work.

[0077] In other words, the electronic cigarette according to the utility model can also detect the components and content of the smoke oil, so as to determine whether the tested smoke oil is qualified according to the detected smoke oil components and content. If the tested smoke oil is qualified, the heating element can continue to heat by controlling the microcontroller. In terms of heating method, the microcontroller can select the corresponding heating program in the preset program according to the identified smoke oil components and content, so as to provide a heating method that matches the smoke oil, thereby improving the taste. If the tested smoke oil is unqualified or lacks smoke oil, the microcontroller controls the heating element to stop heating, and can output an alarm message to remind you to change the smoke oil.

[0078] See also Figures 1 to 3 , Figure 5 as well as Figure 8 For example, the confluence hole 111d can be connected to the input hole 115a of the smoke generator 115 by a detachable connection such as screw connection or clamp connection. After removing the smoke bomb 130, the smoke generator 115 can be disassembled to expose the detection device 116 and the heating element. This makes it convenient for the user to clean the heating element and the detection device 116, and also to clean the disassembled smoke generator 115.

[0079] The above-mentioned detection device 116 can be configured as an integrated detection head in the related art that can be used to detect the components of smoke oil and their content.

[0080] See also Figures 1 to 3 , Figure 5 as well as Fig. 9 For example, the smoke cartridge 130 has a first sealing portion 134 and a second sealing portion 135. The first sealing portion 134 is arranged corresponding to the water holding chamber 131. The second sealing portion 135 is arranged corresponding to the smoke oil holding chamber 132. The first sealing portion 134 and the second sealing portion 135 are configured to be puncturable. The shell 111 may include a first sharp portion 111f and a second sharp portion 111h. The first connecting hole 111g is arranged through the first sharp portion 111f. The second connecting hole 111i is arranged through the second sharp portion 111h. When the shell 111 is connected to the smoke cartridge 130, the first sharp portion 111f penetrates the first sealing portion 134, and the second sharp portion 111h penetrates the second sealing portion 135.

[0081] Furthermore, the first sealing portion 134 and the second sealing portion 135 can be constructed of metal foil such as aluminum foil. The cigarette cartridge 130 has a first outlet and a second outlet. The aluminum foil is heated and pressed by a heat sealing device and joined at the first outlet to form the first sealing portion 134. The aluminum foil is heated and pressed by a heat sealing device and joined at the second outlet to form the second sealing portion 135.

[0082] See also Figure 1 , Figure 2 as well as Fig. 9 For example, a smoke channel 133 is formed in the smoke cartridge 130 between the water receiving chamber 131 and the smoke oil receiving chamber 132. The smoke oil channel 111c runs through the smoke cartridge 130. One end of the smoke channel 133 is connected to the smoke generator 115, and the other end forms a mouthpiece for the smoker or is connected to the mouthpiece for the smoker. By arranging the smoke channel 133 between the water receiving chamber 131 and the smoke oil receiving chamber 132, the space in the smoke cartridge 130 can be divided into two parts, the water receiving chamber 131 and the smoke oil receiving chamber 132, and the structural layout is more reasonable.

[0083] Continue reading Figure 1 , Figure 2 as well as Fig. 9 For example, the volume of the water receiving chamber 131 is less than or equal to the volume of the smoke oil receiving chamber 132. In this way, more water can be stored in the water receiving chamber 131, so as to be used to dilute the smoke oil output by the smoke cartridge 130, thereby helping to adjust the taste of the smoke oil mist.

[0084] It can be understood that in some other examples, the volume of the water containing chamber 131 may be greater than the volume of the smoke oil containing chamber 132 .

[0085] For example, the cigarette cartridge 130 may be a bottle component made of a non-toxic, food-grade, transparent material such as polypropylene (PP).

[0086] According to the electronic cigarette of the utility model, the cartridge 130 includes a water containing chamber 131 and a smoke oil containing chamber 132. After the heating program is started, the gas of water and smoke oil can also generate airflow under the action of the forward Tesla valve channel in the smoke flow channel 133 without suction, so that the electronic cigarette 100 can also generate smoke of different sizes without suction. The size of the smoke here varies adaptively according to the suction force of the most recent suction. The microcontroller can determine the authenticity of the smoke oil in the cartridge 130 and whether the smoke oil is used up according to the detection data of the detection device 116, thereby controlling the working state of the heating element and reminding to replace the smoke oil. The reverse Tesla valve channel in the water flow channel 111b and the smoke oil flow channel 111c is used to slow down the flow of smoke oil and water, control the speed at which the smoke oil and water are supplied to the heating element by the cartridge 130, thereby preventing the smoke oil from being insufficiently atomized due to excessive supply of smoke oil and water, thereby preventing the smoke from having a bad taste, and also helping to prevent the heating element from affecting the heating program due to deposited stains. When the unused electronic cigarette 100 is put into a pocket or placed in a car, the electronic cigarette 100 may sway and shake. The Tesla valve channel located in the opposite direction of the water flow channel 111b and the smoke oil flow channel 111c can effectively prevent the water and smoke oil from splashing and overflowing.

[0087] The electronic cigarette of the utility model can be in the shape of a pipe pot, a hookah, etc., to meet the aesthetic needs of different groups of people. When used with a heating element, the electronic cigarette of the utility model can generate different levels of smoke even when not inhaled, so as to meet the use needs in use scenarios such as writing or thinking about problems, making decisions, liking to light tobacco and smell the smoke or being surrounded by smoke, so as to reduce the damage to health caused by inhaling real smoke.
