[0034] See Figure 1 The present invention provides an airway structure, which is arranged on the host 100 of the electronic cigarette.
[0035] The airway structure includes a host 100 , which has a first end 110 , and the first end 110 of the host 100 is used to connect with the cigarette cartridge 200 to provide power to the cigarette cartridge 200 .
[0036] It is understood that the cigarette cartridge 200 is a common structure that generates smoke by heating a substance such as tobacco oil, which is then inhaled by the user. In some embodiments, the cigarette cartridge 200 can be disposable. That is, after the tobacco oil in the cigarette cartridge 200 is used up, a new cigarette cartridge 200 can be installed in the main unit 100. The cigarette cartridge 200 can adopt existing technology, and the specific structure of the cigarette cartridge 200 is not described in detail in this embodiment.
[0037] Furthermore, a buffer groove 120 is provided at the first end 110 of the main unit 100 , and the buffer groove 120 corresponds to the air inlet 210 of the cigarette cartridge 200 , so that the gas flowing out of the buffer groove 120 can enter the cigarette cartridge 200 through the air inlet 210 .
[0038] A first protrusion 130 protruding from the bottom of the buffer groove 120 is provided in the buffer groove 120. The end surface of the first protrusion 130 is lower than the end surface of the buffer groove 120. An air outlet channel 131 connecting the air duct inside the host 100 is provided on the first protrusion 130 in the vertical direction.
[0039] The end surface of the first protrusion 130 is lower than the end surface of the buffer groove 120 to avoid interference with the connection between the cartridge 200 and the host 100. At the same time, it is beneficial for the gas flowing out through the air outlet channel 131 to flow into the air inlet 210 of the cartridge 200 through the buffer groove 120.
[0040] Furthermore, the air outlet channel 131 and the air inlet hole 210 of the cigarette cartridge 200 are not in the same vertical direction. This method can prevent the oil in the cigarette cartridge 200 from leaking out of the air inlet hole 210 and directly entering the main unit 100 through the air outlet channel 131. At the same time, it can also prevent the condensate of the cigarette cartridge 200 from leaking out of the air inlet hole 210 and directly entering the main unit 100 through the air outlet channel 131.
[0041] When the user smokes the cigarette cartridge 200, external gas can enter the main unit 100 through the air passage of the main unit 100 and flow to the buffer tank 120 through the air outlet channel 131, and then enter the cigarette cartridge 200 through the air inlet 210 of the cigarette cartridge 200 through the buffer tank 120.
[0042] It is understandable that the host 100 generally has an inlet for external air to enter, and the inlet is connected to the airway inside the host 100, such as a specially opened air hole, or a charging port.
[0043] In the air duct structure of the present application, a buffer groove 120 is set on the first end 110 connected to the cigarette cartridge 200 on the main unit 100, and a first protrusion 130 protruding from the bottom of the buffer groove 120 is set in the buffer groove 120, and the first protrusion 130 is provided with an air outlet channel 131 for connecting to the air duct inside the main unit 100, and the air outlet channel 131 and the air inlet hole 210 of the cigarette cartridge 200 are not in the same vertical direction. In this way, the smoke oil and condensate in the cigarette cartridge 200 will not directly enter the main unit 100 through the air outlet channel 131 after leaking out from the air inlet hole 210, but will flow into the buffer groove 120. Since the air outlet channel 131 is set on the first protrusion 130 protruding from the bottom of the buffer groove 120, the smoke oil and condensate in the buffer groove 120 will not flow into the main unit 100 from the air outlet channel 131. In other words, the airway structure of the present application can prevent the oil and condensate in the cigarette cartridge 200 from leaking through the air inlet 210 and flowing directly into the main unit 100.
[0044] Combine Figures 1 to 4 In some embodiments, in order to further prevent smoke oil and condensate from entering the host 100, a seal 140 may be further provided in the buffer tank 120. The seal 140 is provided with a first protrusion 130 protruding from the surface of the seal 140. The bottom of the buffer tank 120 is also provided with an air hole 121. The air hole 121 is connected to the interior of the host 100, and the air hole 121 and the air outlet channel 131 are not in the same vertical direction. The seal 140 is also provided with an air channel 141 connecting the air outlet channel 131 and the air hole 121.
[0045] The smoke oil and condensate leaked from the smoke cartridge 200 can flow onto the seal 140 in the buffer tank 120. Since the first protrusion 130 protrudes from the surface of the seal 140, the smoke oil and condensate will remain on the surface of the seal 140 and will not flow into the air outlet channel 131. Even if a small amount of smoke oil and condensate on the surface of the seal 140 is introduced into the air outlet channel 131 due to vibration, shaking, etc., this part of the smoke oil and condensate will remain in the air outlet channel 131 and the air passage 141, avoiding direct flow into the host 100 through the air hole 121.
[0046] In some embodiments, in order to further prevent the smoke oil and condensate from flowing directly into the host 100 through the air hole 121, a second protrusion 122 is provided in the buffer tank 120, and the second protrusion 122 is provided with the air hole 121 in the vertical direction. The sealing member 140 is provided with a receiving groove 142 connected to the air channel 141, and the second protrusion 122 is located in the receiving groove 142.
[0047] Specifically, the air passage 141 is an air guide groove provided on the bottom side of the seal 140 near the buffer groove 120, and the air guide groove connects the air outlet channel 131 and the accommodating groove 142. This method can maximize the height difference between the lowest point of the air passage 141 and the end of the second protrusion 122, and can better prevent smoke oil and condensate from entering the air hole 121.
[0048] Furthermore, the receiving groove 142 provided in the sealing member 140 extends and protrudes from the end surface of the sealing member 140, and the second protrusion 122 protrudes from the end surface of the sealing member 140 within the receiving groove 142. This arrangement not only ensures that the receiving groove 142 is connected to the air passage 141 (i.e., the air passage 121 of the second protrusion 122 within the receiving groove 142 is connected to the air passage 141), but also increases the height of the second protrusion 122, further preventing smoke oil and condensate from entering the air passage 121.
[0049] Combine Figure 4 and Figure 6 The present application also provides an electronic cigarette, a cartridge 200 and an airway structure in an embodiment of the present application, wherein the cartridge 200 is arranged on the first end 110 of the host 100, and the air inlet 210 of the cartridge 200 is connected to the buffer groove 120.
[0050] During use, the user can inhale from the mouthpiece 220 of the cigarette cartridge 200. During the inhalation process, the external airflow can enter the main unit 100, for example, through the inlet on the main unit 100, enter the airway inside the main unit 100, and flow out to the buffer tank 120 through the air outlet channel 131 connected to the airway, and finally enter the cigarette cartridge 200 from the air inlet hole 210 of the cigarette cartridge 200.
[0051] Furthermore, the electronic cigarette may also include a shell 300, the host 100 is mounted in the shell 300, and a receiving groove 142 is provided at one end of the shell 300, the receiving groove 142 is used to receive the cigarette cartridge 200, and the cigarette cartridge 200 is connected to the first end 110 of the host 100 through the receiving groove 142.
[0052] Specifically, the housing 300 can protect the host 100 , and at the same time, the housing 300 can also provide a certain degree of protection for the connection between the cigarette cartridge 200 and the host 100 , thereby preventing the cigarette cartridge 200 from being easily detached from the host 100 .
[0053] Furthermore, the electronic cigarette may also include a first spring pin 150 and a second spring pin 230. The first spring pin 150 is respectively arranged at the first end 110 of the main unit 100 and located on both sides of the buffer slot 120. The first spring pin 150 is respectively electrically connected to the PCB board inside the main unit 100. The second spring pin 230 is electrically connected to the atomizer core in the cigarette cartridge 200. When the cigarette cartridge 200 is set at the first end 110 of the main unit 100, the first spring pin 150 and the second spring pin 230 are in contact and connected with each other.
[0054] Furthermore, the electronic cigarette also includes a first magnetic component 160 and a second magnetic component 240. The first magnetic component 160 is arranged at the first end 110 of the main unit 100 and is located on both sides of the buffer slot 120. The second magnetic component 240 is arranged at the end of the cigarette cartridge 200 close to the main unit 100. When the cigarette cartridge 200 is arranged at the first end 110 of the main unit 100, the first magnetic component 160 and the second magnetic component 240 are connected to each other. This method can quickly realize the detachability between the main unit 100 and the cigarette cartridge 200.
[0055] Furthermore, the electronic cigarette also includes a sensing microphone (not shown in the figure), which is arranged in the host 100, corresponds to the air outlet channel 131, and is connected to a PCB board (not shown in the figure). The sensing microphone is used to sense the airflow flowing into the air outlet channel 131, and then send the sensing signal to the PCB board. The PCB board controls the operation of the atomization core of the cigarette cartridge 200 through the connection between the first spring pin 150 and the second spring pin 230.
[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of some utility models should be included in the scope of protection of some utility models.
