Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomizer structures, in particular to an electronic atomizer. Background Art

[0002] Electronic vaporizers, also known as virtual cigarettes, steam cigarettes, e-cigarettes, and aerosol generating devices, are primarily used to simulate the sensation of smoking without compromising health, either as a smoking cessation aid or as a cigarette replacement. Currently, most electronic vaporizers include a microphone (an air pressure sensor) as a switching element. When the user inhales, the microphone senses the change in air pressure, turning on the heating circuit within the electronic vaporizer to heat and atomize the e-liquid.

[0003] For left-right split electronic atomizers, the microphone is typically located inside the cigarette holder (due to the appearance and structure of the cigarette cartridge, there's generally not enough space inside the cartridge to accommodate a microphone). The air inlet is also located on the cigarette holder, with an air channel between the cigarette holder and the cartridge. During inhalation, outside air first enters the cigarette holder through the air inlet, triggering the microphone. It then passes through the air channel into the main airway within the cigarette cartridge, and finally exits through the smoke outlet on the cartridge (for the specific structure of left-right split electronic atomizers, refer to patents such as CN115606850A). Because the air inlet is located on the cigarette holder, the entire airway becomes tortuous, increasing the user's inhalation resistance and reducing the user experience. Utility Model Content

It should be understood that the use of directional terms should not limit the scope of protection claimed in this utility model.

[0030] like Figures 1 to 8As shown, the electronic atomizer provided by the embodiment of the present invention includes a cigarette rod 2 and a cigarette cartridge 1, which are arranged in left and right parts (i.e., the cigarette rod 2 and the cigarette cartridge 1 are arranged on the left and right, and the cigarette rod 2 and the cigarette cartridge 1 are detachably connected). The cigarette cartridge 1 includes a first shell 11 and an atomizer assembly 10 arranged in the first shell 11. The atomizer assembly 10 includes an atomizer core 12; the atomizer core 12 is used to generate heat when powered on to heat and atomize the atomized liquid (such as tobacco oil) to produce smoke. A main airway 100 is provided in the first shell 11, and the atomizer core 12 is disposed in the main airway 100. An air inlet 111 and a smoke outlet 112 are provided on the first shell 11. The air inlet 111 and the smoke outlet 112 are both connected to the main air duct 100, and along the flow direction S of the airflow, the air inlet 111 and the smoke outlet 112 are respectively located upstream and downstream of the main air duct 100 (that is, when inhaling, the outside air can enter the main air duct 100 through the air inlet 111 and finally be discharged through the smoke outlet 112).

[0031] The cigarette holder 2 includes a second housing 21 (only a portion of the second housing 21 is shown in the figure), an air pressure sensing element 22 (i.e., a microphone) and a power supply assembly 23 disposed within the second housing 21. The air pressure sensing element 22 is electrically connected to the power supply assembly 23, which is used to power the atomizer core 12. The air pressure sensing element 22 acts as a switch element, controlling the on / off circuit between the power supply assembly 23 and the atomizer core 12. An air pressure sensing duct 200 is provided within the second housing 21, and the air pressure sensing element 22 is disposed within the air pressure sensing duct 200. When the cigarette cartridge 1 and cigarette holder 2 are assembled, the air pressure sensing duct 200 communicates with the main air duct 100.

[0032] The electronic atomizer provided by the embodiment of the present invention sets the air inlet 111 on the first shell 11 of the cigarette cartridge 1. When inhaling, the outside air can directly enter the main airway 100 through the air inlet 111 and mix with the smoke generated by the heating of the atomizer core 12, and then be discharged through the smoke outlet 112, thereby reducing the turning of the airway (that is, the air inlet does not need to extend from the cigarette rod to the cigarette cartridge), reducing the inhalation resistance, improving the smoothness of the inhalation, and thus improving the user experience. At the same time, by An induction airway 200 is provided in the second housing 21, and an air pressure sensing element 22 is provided in the induction airway 200. During inhalation, the gas in the induction airway 200 can be sucked into the main airway 100, causing the air pressure in the induction airway 200 to decrease (the induction airway 200 is generally at a negative pressure). The air pressure sensing element 22 opens after sensing the change in air pressure, thereby connecting the power supply component 23 to the atomizer core 12 and supplying power to the atomizer core 12, so that the air pressure sensing element 22 can function as a normal switch.

[0033] As an embodiment, the atomizer core 12 includes a porous substrate and a heating structure disposed on the porous substrate. The porous substrate may be porous ceramic, porous glass, etc., and the heating structure may be a heating wire, a heating circuit, etc. After being electrically connected to the power supply component 23, the heating structure can heat the atomized liquid on the porous substrate to generate vapor.

[0034] like Figure 7 and Figure 8 As shown, as an embodiment, the induction air channel 200 is communicated with an end of the main air channel 100 close to the air inlet 111 .

[0035] like Figure 4 and Figure 7 As shown, as an embodiment, the atomizer assembly 10 further includes a support seat 13, the main air duct 100 includes an atomizing chamber 130 arranged in the support seat 13, a flue 141 located above the atomizing chamber 130 and a cavity 15 located below the atomizing chamber 130, the atomizer core 12 is arranged in the atomizing chamber 130 (that is, the atomizer core 12 is arranged in the support seat 13), and the atomizer core 12 can generate smoke in the atomizing chamber 130.

[0036] The smoke outlet 112 and the air inlet 111 are respectively arranged at the top and bottom of the first shell 11. The atomization chamber 130 is connected to the smoke outlet 112 through the flue 141, and the atomization chamber 130 is connected to the air inlet 111 through the cavity 15. When the cigarette cartridge 1 and the cigarette rod 2 are assembled, the sensing airway 200 is connected to the cavity 15.

[0037] Specifically, in this embodiment, the support base 13 can support and fix the atomizer core 12. During inhalation, external air can enter the cavity 15 through the air inlet 111, then enter the atomizer chamber 130, mix with the smoke generated by the heating of the atomizer core 12, and finally enter the flue 141 and be discharged through the smoke outlet 112. At the same time, during inhalation, the gas in the sensing airway 200 can be drawn into the cavity 15, reducing the air pressure in the sensing airway 200, thereby causing the air pressure sensing element 22 to open after sensing the change in air pressure.

[0038] like Figure 4 and Figure 7 As shown, as an embodiment, the support base 13 is disposed in the middle of the first shell 11, and the cavity 15 is formed by the support base 13 and the inner wall of the first shell 11. Of course, in other embodiments, the cavity 15 can also be disposed in the support base 13.

[0039] like Figure 4 and Figure 7As shown, as an embodiment, a smoke guide rod 14 extending from top to bottom is provided in the first shell 11, and a smoke duct 141 is provided in the smoke guide rod 14 from top to bottom, and the smoke duct 141 is provided vertically. A through hole 134 is provided on the support base 13 to communicate with the atomization chamber 130. The top end of the smoke guide rod 14 is connected to the inner wall of the first shell 11 (specifically, the smoke guide rod 14 and the first shell 11 are an integral structure), and the bottom end of the smoke guide rod 14 is inserted into the through hole 134, thereby communicating with the atomization chamber 130 and the smoke duct 141. Of course, in other embodiments, the smoke guide rod 14 can also be fixedly connected to the support base 13, and the smoke duct 141 can also be provided in the support base 13.

[0040] like Figure 7 As shown in the figure, as an embodiment, a liquid storage chamber 16 is provided in the first housing 11 for storing atomized liquid. The liquid storage chamber 16 is located above the support base 13. A liquid outlet 131 is provided on the support base 13 at a position corresponding to the atomizer core 12. The atomized liquid stored in the liquid storage chamber 16 can be transferred to the atomizer core 12 through the liquid outlet 131, so that the atomizer core 12 can generate heat and atomize the atomized liquid when powered on.

[0041] like Figure 7 As shown, as an embodiment, the liquid storage chamber 16 is formed by the support base 13, the smoke guide rod 14 and the inner wall of the first shell 11. Of course, in other embodiments, an oil storage body (not shown) for storing atomized liquid can also be additionally provided in the first shell 11.

[0042] like Figure 7 As shown, as an embodiment, the main air duct 100 further includes an air inlet 133 provided on the support base 13, and the atomizing chamber 130 is connected to the cavity 15 through the air inlet 133. The atomizing core 12 and the flue 141 are both located above the air inlet 133, and the atomizing core 12 and the air inlet 133 are arranged in a vertically corresponding manner, and the flue 141 and the air inlet 133 are arranged in a vertically staggered manner. With such a configuration, during inhalation, when the air in the cavity 15 enters the atomizing chamber 130 through the air inlet hole 133, since the atomizing core 12 and the air inlet hole 133 correspond to each other in upper and lower directions, the air entering the atomizing chamber 130 can directly impact the atomizing core 12, thereby supplying air to the atomizing core 12 more quickly and taking away the smoke generated by the atomizing core 12, thereby improving the atomization efficiency of the atomizing core 12; at the same time, since the flue 141 and the air inlet hole 133 are staggered in upper and lower directions, the condensate generated in the flue 141 (the smoke in the atomizing chamber 130 will partially condense after entering the flue 141 to generate condensate) will not directly drip into the cavity 15 through the air inlet hole 133, thereby preventing the condensate from being discharged from the air inlet port 111 and affecting the user experience.

[0043] Specifically, in this embodiment, the atomizing chamber 130 includes a mounting groove 136 disposed in the support base 13, and the atomizing core 12 is disposed in the mounting groove 136. The liquid outlet 131 is disposed directly above the mounting groove 136, and the air inlet 133 is disposed directly below the mounting groove 136.

[0044] like Figure 7 As shown, as an embodiment, a liquid collection tank 135 communicating with the atomizing chamber 130 is further provided in the support base 13. The liquid collection tank 135 is located directly below the flue 141. A liquid absorbing member (not shown) is provided in the liquid collection tank 135.

[0045] Specifically, by providing the liquid accumulating groove 135 and disposing a liquid absorbing member in the liquid accumulating groove 135, the condensed liquid generated in the flue 141 can drip onto the liquid absorbing member and be absorbed by the liquid absorbing member. At the same time, the liquid absorbing member can also absorb the condensed liquid generated in the atomizing chamber 130, thereby preventing the condensed liquid from being discharged outside the first housing 11. The liquid absorbing member can specifically be oil-absorbing cotton or the like.

[0046] like Figure 3 and Figure 7 As shown, as an embodiment, a branch airway 132 is provided on the support seat 13, and a first air hole 113 is provided on the first shell 11, the first air hole 113 corresponds to the branch airway 132, and one end of the branch airway 132 is connected with the cavity 15; when the cigarette cartridge 1 and the cigarette rod 2 are assembled, the other end of the branch airway 132 is connected with the sensing airway 200 through the first air hole 113, that is, the sensing airway 200 is connected with the cavity 15 through the first air hole 113 and the branch airway 132 in sequence.

[0047] like Figure 4 and Figure 7 As shown, as an embodiment, the support seat 13 includes an upper heating seat 13A and a lower heating seat 13B that are connected to each other, the upper heating seat 13A is located above the lower heating seat 13B, and the atomization chamber 130 is arranged between the upper heating seat 13A and the lower heating seat 13B. The mounting groove 136 is arranged in the upper heating seat 13A, the perforation 134 is arranged on the upper heating seat 13A, and the air inlet 133 and the branch airway 132 are arranged on the lower heating seat 13B. The liquid storage chamber 16 is formed by the upper heating seat 13A, the smoke guide rod 14 and the inner wall of the first shell 11.

[0048] like Figure 4 and Figure 7As shown, as an embodiment, the support base 13 also includes a sealing sleeve 13C, which is sleeved on the outside of the upper heating base 13A. Part of the sealing sleeve 13C is sandwiched between the outer wall of the upper heating base 13A and the inner wall of the first shell 11, and part of the sealing sleeve 13C is sandwiched between the inner wall of the through-hole 134 and the outer wall of the smoke guide rod 14. The sealing sleeve 13C is mainly used to seal the liquid storage chamber 16. The liquid outlet 131 includes a first through hole 1311 provided on the sealing sleeve 13C and a second through hole 1312 provided on the upper heating base 13A. The first through hole 1311 and the second through hole 1312 are arranged correspondingly up and down. The sealing sleeve 13C can be made of materials such as silicone.

[0049] like Figure 4 and Figure 7 As shown, as an embodiment, a first sealing member 17 is provided on the outer cover of the atomizer core 12. The first sealing member 17 is sandwiched between the atomizer core 12 and the inner wall of the mounting groove 136. The first sealing member 17 can play a sealing role to prevent oil leakage from the atomizer core 12. The first sealing member 17 can be made of materials such as silicone.

[0050] like Figure 4 and Figure 7 As shown, as an embodiment, a second sealing member 18 is further provided in the first housing 11. The second sealing member 18 is provided corresponding to the branch air channel 132 and the first air hole 113. The second sealing member 18 is sandwiched between the outer wall of the lower heating seat 13B and the inner wall of the first housing 11. The second sealing member 18 is used to seal the connection between the branch air channel 132 and the first air hole 113. The second sealing member 18 can be made of a material such as silicone.

[0051] like Figure 3 、 Figure 4 and Figure 7 As shown, as an embodiment, the first shell 11 includes an upper shell 11A and a lower shell 11B connected to each other, the upper shell 11A is located above the lower shell 11B, the air inlet 111 and the first air hole 113 are both arranged on the lower shell 11B, and the smoke outlet 112 is arranged on the upper shell 11A.

[0052] like Figures 2 to 7 As shown, as an embodiment, a mounting base 24 is embedded in the wall of the second housing 21, and the sensing airway 200 is disposed within the mounting base 24, that is, the air pressure sensing element 22 is disposed within the mounting base 24. A first air hole 113 is provided in the first housing 11, communicating with the main airway 100. When the cigarette cartridge 1 and the cigarette rod 2 are assembled, the outer surface of the mounting base 24 is in close contact with the outer wall of the first housing 11, and the sensing airway 200 is in communication with the first air hole 113, thereby achieving a seal between the sensing airway 200 and the first air hole 113. The mounting base 24 can be made of a material such as silicone.

[0053] like Figures 2 to 7 As shown, as an embodiment, the sensing air channel 200 includes a mounting cavity 241 and a vent groove 242 arranged sequentially from the inside to the outside (i.e., the vent groove 242 is located outside the mounting cavity 241). The air pressure sensing element 22 is disposed in the mounting cavity 241, and the outer peripheral surface of the air pressure sensing element 22 is in close contact with the inner wall of the mounting cavity 241. A partition portion 243 is provided between the mounting cavity 241 and the vent groove 242. The sensing air channel 200 also includes a second air hole 244 provided on the partition portion 243, and the mounting cavity 241 and the vent groove 242 are connected through the second air hole 244. When the cigarette cartridge 1 and the cigarette rod 2 are assembled, the ventilation groove 242 is connected to the first air hole 113, that is, the installation cavity 241 is connected to the main air channel 100 through the second air hole 244, the ventilation groove 242, and the first air hole 113 in sequence; when inhaling, the gas in the installation cavity 241 can be sucked into the main air channel 100 through the second air hole 244, the ventilation groove 242 and the first air hole 113 in sequence, so that the air pressure in the installation cavity 241 is reduced, and then the air pressure sensing element 22 opens after sensing the air pressure change.

[0054] Specifically, the cross-sectional area of ​​the second air hole 244 is smaller than the cross-sectional area of ​​the ventilation groove 242 , that is, the size of the second air hole 244 is smaller than the size of the ventilation groove 242 . By setting the size of the ventilation groove 242 to be larger, when the cigarette cartridge 1 and the cigarette rod 2 are assembled, the ventilation groove 242 can better cover the first air hole 113, so that the ventilation groove 242 is connected to the first air hole 113; at the same time, by setting a partition portion 243 between the mounting cavity 241 and the ventilation groove 242, and setting a smaller second air hole 244 on the partition portion 243, the partition portion 243 can shield and protect the air pressure sensing element 22, avoiding the air pressure sensing element 22 from being exposed and affecting the appearance and service life (if the partition portion 243 is not set, or the size of the second air hole 244 is set too large, the air pressure sensing element 22 will be exposed to the external environment over a large area, which will not only affect the service life of the air pressure sensing element 22, but also the air pressure sensing element 22 in the mounting seat 24 can be directly seen from the appearance, thereby affecting the aesthetics).

[0055] like Figure 7 As shown, as an embodiment, the size of the ventilation groove 242 along the vertical direction Y (that is, the height of the ventilation groove 242) is configured as follows: when the cigarette cartridge 1 is assembled with the cigarette rod 2 in the forward direction and when the cigarette cartridge 1 is assembled with the cigarette rod 2 in the reverse direction ( Figure 7(The figure shows the cigarette cartridge 1 being assembled with the cigarette rod 2 in the forward direction), and the ventilation groove 242 can cover the first air hole 113, so that the ventilation groove 242 is connected to the first air hole 113. In this embodiment, the cigarette cartridge 1 and the cigarette rod 2 have the functions of both forward assembly and reverse assembly. That is, when the user is in use, the cigarette cartridge 1 can be assembled with the cigarette rod 2 in both the forward direction and the reverse direction (that is, the cigarette cartridge 1 is assembled with the cigarette rod 2 after being turned upside down), without having to distinguish between the front and the back, thereby facilitating user use. Therefore, in this embodiment, the dimension of the ventilation groove 242 along the vertical direction Y needs to be set relatively large.

[0056] like Figures 2 to 7 As shown, as an embodiment, a rib 245 is provided on the outer surface of the mounting seat 24, and the rib 245 protrudes outward from the outer surface of the second shell 21, and the rib 245 is arranged around the periphery of the ventilation groove 242; when the cigarette cartridge 1 and the cigarette rod 2 are assembled, the rib 245 is in close contact with the outer wall of the first shell 11, thereby achieving sealing between the ventilation groove 242 and the first air hole 113.

[0057] like Figures 2 to 7 As shown, as an embodiment, the power supply assembly 23 includes a circuit board 231 for electrically connecting to the atomizer core 12. The circuit board 231 is located inside the mounting base 24, and the air pressure sensing element 22 is electrically connected to the circuit board 231.

[0058] Specifically, in this embodiment, the power supply assembly 23 also includes a battery (not shown), and the battery is electrically connected to the circuit board 231. An electrical connector 232 is provided on the circuit board 231, and the electrical connector 232 passes through the shell wall of the second shell 21 to be exposed outside the second shell 21. A conductive component (not shown) is provided at the position corresponding to the electrical connector 232 on the cigarette cartridge 1; when the cigarette cartridge 1 and the cigarette rod 2 are assembled, the electrical connector 232 contacts the conductive component, and the circuit board 231 is electrically connected to the atomizer core 12 through the electrical connector 232 and the conductive component. The electrical connector 232 can specifically be a spring thimble or other component. During inhalation, when the air pressure sensing element 22 is opened, the circuit board 231 is connected to the atomizer core 12 and supplies power to the atomizer core 12.
