Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] Electronic cigarettes generally consist of an atomizing component, a mouthpiece, and an electronic control device. The atomizing component contains an atomizing chamber that connects to the mouthpiece. When a user inhales, external air triggers the microphone of the electronic control device, which then activates the atomizing component. The atomizing component atomizes the absorbed e-liquid, and the atomized vapor flows out through the mouthpiece connected to the atomizing chamber for the user to inhale.

[0003] However, the existing e-cigarette design is flawed. The atomizing chamber and mouthpiece are always connected, making it easy to accidentally activate the atomizing components and causing mouthpiece leakage. Utility Model Content

[0004] The main objective of this application is to provide an electronic cigarette that solves the technical problem of the atomizing chamber and the mouthpiece being constantly connected.

[0005] To achieve the above objectives, this application proposes an electronic cigarette, comprising:

[0006] A suction nozzle assembly includes a suction nozzle having a mist-suction channel formed inside the suction nozzle;

[0007] The atomizing component has an atomizing chamber formed inside; and

[0008] An air control assembly is located between the nozzle and the atomizing assembly. The air control assembly includes an air guide tube and a movable valve. The two ends of the air guide tube are respectively used to connect the mist intake channel and the atomizing chamber. The movable valve is at least partially located inside the air guide tube. The movable valve has a first position and a second position. When the movable valve is in the first position, the movable valve closes the air guide tube. When the movable valve is in the second position, the movable valve opens the air guide tube.

[0009] Optionally, the movable valve is cylindrical and includes a sealing end. The sealing end is sealed, and a connecting hole is provided on the peripheral wall of the movable valve, the connecting hole being close to the sealing end. When the movable valve is in the first position, the connecting hole coincides with the air guide cylinder. When the movable valve is in the second position, the sealing end is located outside the air guide cylinder, and the connecting hole is at least partially located outside the end of the air guide cylinder near the sealing end.

[0010] Optionally, the sealing end is the end of the movable valve near the mist suction channel.

[0011] Optionally, the gas control assembly includes a limiting member connected to the sealing end. When the active valve is in the first position, the limiting member abuts against the gas guide cylinder.

[0012] Optionally, the nozzle assembly further includes a housing, the nozzle being disposed at one end of the housing, and the air control assembly being at least partially located within the housing.

[0013] Optionally, the nozzle assembly further includes a connecting tube located inside the housing, one end of the connecting tube being connected to the housing, the connecting tube communicating with the mist suction channel, the connecting tube being connected to the air guide tube, and the movable valve being movable within the connecting tube along the axial direction of the connecting tube.

[0014] Optionally, the atomizing component has a detached state and an assembled state; when the atomizing component is in the detached state, the atomizing component is detached from the gas control component, and the movable valve is in the first position; when the atomizing component is in the assembled state, the atomizing component is connected to the gas control component, and the movable valve is in the second position.

[0015] Optionally, the air control assembly includes an elastic element, one end of which is located inside the air guide cylinder and sleeved outside the movable valve, and the other end of which is used to abut against the atomizing assembly. The elastic element is used to cooperate with the atomizing assembly and the air guide cylinder to limit the movable valve, and the movable valve is in the second position under the action of the elastic element, the atomizing assembly and the air guide cylinder.

[0016] Optionally, the number of atomizing components is at least two, and the number of air control components is the same as the number of atomizing components and is set in a one-to-one correspondence.

[0017] Optionally, the number of atomizing components is two, and the number of mist-absorbing channels is two, each corresponding to one of the air-controlling components.

[0018] In this electronic cigarette application, when the active valve is in the first position, it closes the airflow tube, preventing the atomizing component from atomizing the e-liquid, or preventing the atomized e-liquid from flowing into the suction channel for inhalation. When the active valve is in the second position, it opens the airflow tube, connecting the suction channel, airflow tube, and atomization chamber, allowing the atomizing component to atomize the e-liquid. Therefore, by controlling the opening and closing of the airflow tube, the atomization process can be controlled, making this electronic cigarette suitable for both single-atomizing-component and multi-atomizing-component (switching or mixed) applications. Furthermore, when the active valve closes the airflow tube, the e-liquid in the atomization chamber cannot leak from the suction channel, resulting in good sealing of this electronic cigarette.

[0029] This application discloses an electronic cigarette, which includes a mouthpiece assembly, an atomizing assembly, and a gas control assembly. The mouthpiece assembly includes a mouthpiece with a mist-drawing channel formed inside. The atomizing assembly has an atomizing chamber formed inside. The gas control assembly is located between the mouthpiece and the atomizing assembly. The gas control assembly includes an air guide tube and an active valve. The two ends of the air guide tube are used to connect the mist-drawing channel and the atomizing chamber, respectively. The active valve is at least partially located inside the air guide tube and has a first position and a second position. When the active valve is in the first position, the active valve closes the air guide tube. When the active valve is in the second position, the active valve opens the air guide tube.

[0030] In this electronic cigarette application, when the active valve is in the first position, it closes the airflow tube, preventing the atomizing component from atomizing the e-liquid, or preventing the atomized e-liquid from flowing into the suction channel for inhalation. When the active valve is in the second position, it opens the airflow tube, connecting the suction channel, airflow tube, and atomization chamber, allowing the atomizing component to atomize the e-liquid. Therefore, by controlling the opening and closing of the airflow tube, the atomization process can be controlled, making this electronic cigarette suitable for both single-atomizing-component and multi-atomizing-component (switching or mixed) applications. Furthermore, when the active valve closes the airflow tube, the e-liquid in the atomization chamber cannot leak from the suction channel, resulting in good sealing of this electronic cigarette.

[0031] The following will mainly describe the specific structure of electronic cigarettes.

[0032] Please see Figures 1 to 3 The electronic cigarette 100 of this application includes a mouthpiece assembly 110. The mouthpiece assembly 110 includes a mouthpiece 111. The external shape of the mouthpiece 111 can be cylindrical or flat cylindrical, without specific limitation, as long as the mouthpiece 111 can be used to inhale aerosol. An aerosol suction channel 112 is formed inside the mouthpiece 111. The cross-section of the aerosol suction channel 112 can be circular, triangular, polygonal, waist-shaped, elliptical, or irregular in shape.

[0033] Please see Figures 1 to 3The nozzle assembly 110 includes a housing 113, which is a cylindrical structure sealed at one end. The nozzle 111 is disposed on the sealed end of the housing 113. One end of the mist suction channel 112 is located outside the housing 113, and the other end of the mist suction channel 112 communicates with the inner cavity of the housing 113. The cross-section of the housing 113 can be circular, triangular, polygonal, waist-shaped, elliptical, or irregular in shape.

[0034] Please see Figure 1 and Figure 3 The electronic cigarette 100 of this application includes an atomizing component 120, and an atomizing chamber 121 is formed inside the atomizing component 120. The atomizing component 120 includes an atomizing core component (not shown), which is disposed in the atomizing chamber 121 and can adsorb and atomize e-liquid. The atomizing chamber 121 can communicate with the suction channel 112 of the mouthpiece 111, thereby allowing the atomized vapor in the atomizing chamber 121 to flow into the mouthpiece 111 and be inhaled. The communication between the atomizing chamber 121 and the suction channel 112 can be closed, thereby shutting off the operation of the atomizing component 120 and preventing the e-liquid in the atomizing chamber 121 from leaking from the suction channel 112.

[0035] Please see Figures 1 to 3 The electronic cigarette 100 of this application includes a gas control assembly 130. The gas control assembly 130 is located between the mouthpiece 111 and the atomizing assembly 120, and the gas control assembly 130 can control the connection or closure of the mist inhalation channel 112 and the atomizing chamber 121.

[0036] Please see Figures 1 to 3 The air control assembly 130 includes an air guide tube 131 and an active valve 132. The two ends of the air guide tube 131 are used to connect the mist suction channel 112 and the atomizing chamber 121, respectively. The active valve 132 is at least partially located inside the air guide tube 131.

[0037] Please see Figure 3 The actuating valve 132 has a first position and a second position. When the actuating valve 132 is in the first position, it can close the air delivery tube 131; when it is in the second position, it can open the air delivery tube 131. Therefore, by controlling the actuating valve 132 to close or open the air delivery tube 131, the atomization process can be controlled. Simultaneously, when the actuating valve 132 closes the air delivery tube 131, the e-liquid in the atomization chamber 121 cannot leak from the suction channel 112, resulting in good sealing of the electronic cigarette 100.

[0038] Please see Figure 1 and Figure 2The movable valve 132 is cylindrical and includes a sealing end 133. The sealing end 133 is sealed, and a connecting hole 134 is formed on the peripheral wall of the movable valve 132, located near the sealing end 133. The sealing end 133 ensures that the atomization chamber 121's mist can only be discharged through the connecting hole 134, thus enabling the movable valve 132 to open or close the air guide tube 131. The connecting hole 134 can be circular, triangular, polygonal, oblong, elliptical, or irregularly shaped. There can be only one connecting hole 134. (See also...) Figure 1 and Figure 2 The number of connecting holes 134 can be at least two, and at least two connecting holes 134 can be arranged in the circumferential direction of the movable valve 132.

[0039] Please see Figure 3 When the active valve 132 is in the first position, the connecting hole 134 coincides with the air guide tube 131. At this time, the connection of the air guide tube 131 is closed by the sealing end 133, and the connecting hole 134 is closed by the air guide tube 131. The air guide tube 131, the mist suction channel 112 and the atomizing chamber 121 cannot be connected.

[0040] Please see Figure 3 When the movable valve 132 is in the second position, the sealing end 133 is located outside the air guide tube 131, and the connecting hole 134 is at least partially located outside the end of the air guide tube 131 near the sealing end 133. At this time, the mist generated by the atomizing chamber 121 can be discharged from the connecting hole 134, and the air guide tube 131, the mist suction channel 112, and the atomizing chamber 121 are connected (the movable valve 132 is also connected to these three).

[0041] Please see Figure 3 The sealing end 133 is the end of the movable valve 132 that is close to the mist suction channel 112. Thus, the movable valve 132 can move closer to the mist suction channel 112 to open the connection of the air guide tube 131, or move away from the mist suction channel 112 to close the connection of the air guide tube 131.

[0042] Please see Figures 1 to 3 The airflow control assembly 130 includes a limiting member 135 connected to the sealing end 133. When the active valve 132 is in the first position, the limiting member 135 abuts against the air guide tube 131. The limiting member 135 can limit the active valve 132, keeping it in the first position. Therefore, the sealing of the atomizer and the mist intake channel 112 is relatively stable, and the electronic cigarette 100 has good sealing performance.

[0043] Please see Figure 3The gas control component 130 is at least partially located within the housing 113. Thus, the housing 113 can protect the gas control component 130, making the electronic cigarette 100 more compact. Specifically, the wall of the mist inhalation channel 112 is connected to the wall of the air guide tube 131, and the two can be connected by abutment, snap-fit, adhesive, screw, or magnetic attraction.

[0044] Please see Figure 2 and Figure 3 The nozzle assembly 110 also includes a connecting tube 114, which is located inside the housing 113. One end of the connecting tube 114 is connected to the housing 113, and the connecting tube 114 communicates with the mist suction channel 112. (See also...) Figure 3 The connecting cylinder 114 connects to the air guide cylinder 131, and the movable valve 132 can move axially within the connecting cylinder 114. Therefore, the connection of the air guide cylinder 131 is relatively stable, and the movable valve 132 can move to open or close the air guide cylinder 131. The outer wall of the air guide cylinder 131 can abut, snap, adhere, or be screwed to the inner wall of the connecting cylinder 114.

[0045] Please see Figure 3 The atomizing component 120 has a detached state and an assembled state. When the atomizing component 120 is in the detached state, it is disconnected from the air control component 130, and the movable valve 132 is in the first position. When the atomizing component 120 is in the assembled state, it is connected to the air control component 130, and the movable valve 132 is in the second position. The movement of the movable valve 132 can be achieved by assembling the atomizing component 120. When the atomizing component 120 is assembled, it pushes the movable valve 132 toward the mist intake channel 112, opening the seal on the air guide tube 131.

[0046] Please see Figures 1 to 3 The gas control assembly 130 includes an elastic element 136, which may be a spring. (See also...) Figure 3 One end of the elastic element 136 is located inside the connecting cylinder 114 and sleeved outside the movable valve 132. The elastic element 136 can be used to cooperate with the air guide cylinder 131 and the limiting element 135 to limit the movable valve 132. Under the action of the elastic element 136, the air guide cylinder 131 and the limiting element 135, the movable valve 132 is in the first position.

[0047] Specifically, please refer to Figure 3When the movable valve 132 is in the first position, one end of the elastic element 136 abuts against the inner wall of the end of the air guide cylinder 131 near the sealing end 133, the middle part (or the other end) of the elastic element 136 abuts against the end of the movable valve 132 opposite to the sealing end 133, the limiting element 135 abuts against the outer wall of the end of the air guide cylinder 131 near the sealing end 133, and the connecting hole 134 coincides with the air guide cylinder 131. The movable valve 132 is balanced by the three forces of the limiting element 135, the elastic element 136, and the air guide cylinder 131, and the movable valve 132 is stably in the first position.

[0048] Please see Figure 3 The other end of the elastic element 136 is used to abut against the atomizing component 120. The elastic element 136 is used to cooperate with the atomizing component 120 and the connecting cylinder 114 to limit the movable valve 132. The movable valve 132 is in the second position under the action of the elastic element 136, the atomizing component 120 and the connecting cylinder 114.

[0049] Specifically, please refer to Figure 3 When the active valve 132 is in the second position, one end of the elastic element 136 abuts against the inner wall of the end of the air guide cylinder 131 near the sealing end 133, the middle part of the elastic element 136 abuts against the end of the active valve 132 opposite to the sealing end 133, the other end of the elastic element 136 abuts against the atomizing component 120, the limiting element 135 is located outside the end of the air guide cylinder 131 near the sealing end 133 (that is, inside the connecting cylinder 114), the connecting hole 134 is located outside the end of the air guide cylinder 131 near the sealing end 133 (that is, inside the connecting cylinder 114), and the atomizing component 120 abuts against the end of the active valve 132 opposite to the sealing end 133. The active valve 132 is balanced by the three forces of the elastic element 136, the atomizing component 120 and the air guide cylinder 131, and the active valve 132 is stably in the second position.

[0050] The number of atomizing components 120 is at least two; please refer to [link / reference]. Figure 1 The number of airflow control components 130 is the same as the number of atomizing components 120, and they are configured in a one-to-one correspondence. Therefore, the airflow control components 130 can control the operation of different atomizing components 120, making the electronic cigarette 100 of this application suitable for use scenarios with multiple atomizing components 120. There can be one mist intake channel 112, which is connected to the airflow guide tubes 131 of at least two airflow control components 130. Therefore, the configuration of the mist intake channel 112 is relatively convenient. Please refer to... Figure 1 The number of mist-absorbing channels 112 can also be set to match the number of air control components 130, with each channel corresponding to the other. Therefore, the air control components 130 effectively control the connection and closure of the atomizing chamber 121 and the mist-absorbing channels 112.
