The present disclosure relates to the technical field of electronic cigarettes, and in particular, to an atomizer and an electronic cigarette having the same.
The existing electronic cigarette includes an atomizer and a power supply device, wherein the atomizer is provided with a liquid storage assembly for storing cigarette liquid, and under the electric driving of the power supply device, the cigarette liquid in the liquid storage assembly is heated and atomized into smoke for the user to inhale.
The atomizer includes a liquid storage assembly for storing cigarette liquid and an air guiding assembly that is sealed on the liquid storage assembly. The connection between the two is generally a screw connection or a plug connection. When the liquid storage chamber in the liquid storage assembly is sealed after liquid injection, the liquid storage chamber is compressed due to the screwing operation or the plugging operation, thereby increasing the air pressure in the liquid storage chamber, causing excessive cigarette liquid to enter the atomizing head and be absorbed by the liquid absorbing member. When the liquid absorbing member reaches saturation, the excessive cigarette liquid easily enters the air outlet passage, causing the cigarette liquid to leak.
In view of the above, it is necessary to provide an atomizer and an electronic cigarette having the same, to prevent leakage of the cigarette liquid.
The technical solution adopted by the present disclosure to solve the above problem is: an atomizer includes a liquid storage assembly and an air guiding assembly detachably connected to the liquid storage assembly. The liquid storage assembly includes a liquid storage pipe having a liquid storage chamber, a connecting member fixed at one end of the liquid storage pipe, an adjusting member rotatably received in the connecting member, and a pressing cover fixed at one end of the connecting member. A bottom wall of the connecting member is provided with at least one first liquid inlet hole communicating with the liquid storage chamber. The adjusting member is provided with a third liquid inlet hole corresponding to the first liquid inlet hole. The pressing cover is provided with at least one clamping groove. The air guiding assembly includes an air intake cover provided with a clamping claw capable of driving the adjustment member to rotate. The clamping claw cooperates with the clamping groove. When the air intake cover is rotated, the clamping claw drives the adjusting member to rotate along the clamping groove, to cause the third liquid inlet hole to communicate with the first liquid inlet hole or to cause the adjusting member to close the first liquid inlet hole.
Further, the clamping claw includes a first claw and a second claw. The adjustment member is provided with at least one limiting slot offset from the third liquid inlet hole. The first claw is engaged in the limiting slot, and the second claw is rotatable along the clamping groove.
Further, the clamping groove is an L-shaped groove. Each L-shaped groove includes a notch defined in an inner wall of the pressing cover along an axial direction of the pressing cover and extending to an upper surface of the pressing cover and a locking slot extending along a circumferential direction of the pressing cover from a lower end of the notch. The second claw is able to enter from the notch to be rotatable and engaged in the locking slot.
Further, an upper surface of the adjusting member is provided with at least one pair of limiting protrusions. The limiting slot is formed by a gap between the two limiting protrusions of each pair of the limiting protrusions.
Further, a limiting portion is protruded from a lower end of the air intake cover adjacent to the liquid storage assembly. The first claw is formed on an outer circumferential surface of the limiting portion, and the second claw is formed on the first claw away from the limiting portion.
Further, the liquid storage assembly further includes a sealing member. The sealing member is fixedly received in one end of the connecting member opposite to the pressing cover. The sealing member is provided with a second liquid inlet hole communicating with the first liquid inlet hole.
Further, the air guiding assembly further includes an air regulating member sleeved on the air intake cover, an air outlet pipe detachably connected to the air intake cover, and a mouthpiece connector detachably connected to an upper end of the air outlet pipe. At least one air intake hole is defined in a side wall of the air intake cover. An air regulating groove communicating with the outside environment is defined in an inner side wall of the air regulating member corresponding to the air intake hole. The air regulating groove is enabled to communicate with or stagger from the air intake hole when the air regulating member is rotated. An inner space of the air outlet pipe forms an air outlet passage communicating with the mouthpiece connector.
Further, the atomizer further includes an atomizing assembly received in the liquid storage assembly. The atomizing assembly includes an atomizing head and a vent pipe detachably connected to an upper end of the atomizing head. An outer circumferential surface of the vent pipe is detachably connected to the connecting member. The vent pipe is sleeved on the air outlet pipe. A space between an inner wall of the vent pipe and an outer wall of the air outlet pipe forms an air inlet passage communicating with the air intake hole. The atomizing head is in communication with the air inlet passage and the air outlet passage, respectively.
Further, the liquid storage assembly further includes a sleeve pipe sleeved on the liquid storage pipe. The connecting member is mounted to an upper end of the sleeve pipe.
An electronic cigarette includes the above atomizer.
The beneficial effects of the present disclosure are: in the atomizer or the electronic cigarette provided by the present disclosure, the adjusting member on the liquid storage assembly is rotated by the air guiding assembly, so that the cigarette liquid is sealed in the liquid storage chamber. During the sealing process, the liquid storage chamber is prevented from being compressed to cause the pressure in the liquid storage chamber to rise, thereby avoiding leakage of excessive cigarette liquid from the air outlet passage. In addition, when the air guiding assembly and the liquid storage assembly are locked, the children are prevented from easily opening the atomizer to avoid contact or ingestion of the cigarette liquid.
The present disclosure will now be further described with reference to the accompanying drawings and embodiments.
The part names and their reference signs in the figures are:
The present disclosure will now be described in detail in conjunction with the drawings. These drawings are simplified schematic diagrams illustrating the basic structure of the present disclosure only in a schematic manner, and thus they show only the configuration related to the present disclosure.

During liquid injection, the cigarette liquid is finally injected into the liquid storage chamber 121 sequentially through the third liquid inlet holes 153, the second liquid inlet holes 144 and the first liquid inlet holes 132, until the liquid injection process is finished. When the air guiding assembly 30 is assembled with the liquid storage assembly 10, the space in the liquid storage chamber 121 is compressed, the air in the liquid storage chamber 121 is discharged from the liquid storage assembly 10 by passing through the first liquid inlet holes 132 of the connecting member 13, the second liquid inlet holes 141 of the sealing member 14 and the third liquid inlet holes 153 of the adjusting member 15, so that the cigarette liquid in the liquid storage chamber 121 is avoided to be compressed into the vent pipe 42 by passing through the atomizing head 41. Referring to
When it is required to perform liquid injection, the air guiding assembly 30 is reversely rotated, and the adjusting member 15 is reversely rotated by the air intake cover 31, so that the second liquid inlet holes 141 and the third liquid inlet holes 153 are communicated with each other. At the same time, the second claw 3142 of the air intake cover 31 is finally separated from the pressing cover 16 through the locking slot 162 and the notch 161, and the air guiding assembly 30 can be separated from the liquid storage assembly 10.
When the user sucks, the air regulating member 32 can be rotated to adjust the overlapping area of the air regulating groove 321 and the air intake hole 311 to control the amount of air intake. The external air enters through the air regulating groove 321, the air intake hole 311 and the air inlet passage 421 in sequence, mixes with the smoke, and then enters the user's mouth through the air outlet passage 333 and the mouthpiece connector 34 in sequence.
In the atomizer 100 of the present disclosure, the air intake cover 31 can drive the adjusting member 15 to rotate, to close or open the liquid storage chamber 121, and also to lock or separate the air guiding assembly 30 and the liquid storage assembly 10. Compared with the conventional methods by threads and plugging, when the atomizer 100 of the present disclosure closes the liquid storage chamber 121, the liquid storage chamber 121 is prevented from being compressed, the leakage of the cigarette liquid due to the excessive high pressure of the liquid storage chamber 121 is not caused. In addition, when the air guiding assembly 30 and the liquid storage assembly 10 are locked, the children are prevented from easily opening the atomizer by a single action to avoid contact or ingestion of the cigarette liquid.
The present disclosure also provides an electronic cigarette having the atomizer 100 described above and a power supply device (not shown) connected to the atomizer 100, so that the electronic cigarette has the same technical effects as the atomizer 100 described above.
In view of the above-described embodiments of the present disclosure, various changes and modifications can be made by those skilled in the art without departing from the scope of the present disclosure. The scope of the present disclosure is not limited to the contents of the specification, and the scope thereof must be determined in accordance with the scope of the claims.
