In this embodiment, the locking member 434 is inserted into the movable member 433, and it should be understood that in other embodiments not shown, the locking member 434 may also be connected to the movable member 433 by clamping or gluing, or the locking member 434 and the movable member 433 are integrally formed, which is not limited herein.

Referring again to FIG. 1, to improve the sealing ability of the locking member 434 to close the injection port 402, a gasket 45 is disposed around the injection port 402.

A first connecting piece 4342 is arranged on the surface, away from the movable piece 433, of the locking piece 434, in a downward protruding manner, in a socket 4154 close to the stop piece 415, one end, away from the locking piece 434, of the first connecting piece 4342 extends outwards to form a claw 4343, a clamping groove 4344 matched with the protrusion 4181 is concavely arranged on the surface, away from the locking piece 434, of the claw 4343, the claw 4343 can be inserted into the cavity 4153 through the socket 4154, and when the locking piece 434 translates, the claw 4343 can move in the cavity 4153 under the driving of the locking piece 434, so that the protrusion 4181 is clamped into the clamping groove 4344, or the protrusion 4181 is separated from the clamping groove 4344. It is understood that the first connection part 4342, the jaw 4343 and the catching groove 4344 together constitute the second connection part 421. When the cover 50 is in the locked position, the first connecting portion 422 is engaged with the second connecting portion 421, and at this time, the protrusion 4181 is engaged with the engaging groove 4344, and the periphery of the socket 4154 abuts against the engaging claw 4343, so as to limit the turning motion of the locking member 434 relative to the connecting assembly 40. In this embodiment, the protrusion 4181 is made of an elastic material, and the protrusion 4181 deforms and is engaged with the engaging groove 4344. It will be appreciated that in other embodiments, not shown, the pawl 4343 is made of a resilient material and the pawl 4343 is deformed such that the projection 4181 snaps into the catch 4344.

Of course, it is understood that in other embodiments, which are not shown, the first connection portion 422 and the second connection portion 421 are both provided with a magnetic member such as a magnet, and the first connection portion 422 and the second connection portion 421 are magnetically connected when the cover 50 is in the locking position. Specifically, the second connection portion 421 includes a claw 4343, the claw 4343 itself is a magnetic member or a magnetic member is disposed thereon, the first connection portion 422 includes a fastening member 420 and a protrusion 4181, the protrusion 4181 is disposed thereon with a magnetic member such as a magnet, and when the claw 4343 moves to a proper position, the magnetic member on the claw 4343 and the magnetic member of the protrusion 4181 attract each other, so as to lock the locking member 434, and the seal between the cover 50 and the connection assembly 40 is firmer. When the cover 50 is in the unlocked position, the first connecting portion 422 is disengaged from the second connecting portion 421, and the peripheral edge of the socket 4154 no longer abuts against the claws 4343, so that the cover 50 can be turned over. It is understood that in other embodiments, the first connection portion 422 and the second connection portion 421 may have other shapes, structures and connection manners, for example, the first connection portion 422 and the second connection portion 421 both include claws, the claws of the second connection portion 421 have the same shape as in this embodiment, and the claws of the first connection portion 422 and the claws 3434 have the same shape after being inverted, so that the claws of the two can be engaged with each other.

It is understood that the first connection portion 422 and the second connection portion 421 together form a second locking assembly, and when the cover 50 is moved to the state that the first connection portion 422 and the second connection portion 421 are matched, the cover 50 is locked; when the cover 50 is moved to separate the first connection portion 422 and the second connection portion 421, the cover 50 is unlocked.

The surface of the locking member 434 that deviates from the moving member 433, which is close to the limit groove 4155 of the stop member 415, is convexly provided with a second connecting member 4345, the second connecting member 4345 is in an L-shaped structure, the second connecting member 4345 is matched with the limit groove 4155 and can slide in the limit groove 4155, and a rotating shaft hole 4347 is arranged on the side wall of one end of the second connecting member 4345 extending along the sliding direction. In this embodiment, the cover 50 further includes a rotating shaft 436, the rotating shaft 436 is installed in the rotating shaft hole 4347 and slidably engaged in the translating groove 4156, and when the rotating shaft 436 moves to an end of the translating groove 4156 far from the inserting hole 4154, the cover 50 is turned over, so that the cover 50 can rotate relative to the connecting assembly 40 with the rotating shaft 436 as a rotation center. It should be noted that when the rotating shaft 436 is located at any position in the translating groove 4156, the abutting portion 4191 of the elastic member 419 elastically abuts against the second connecting member 4345.

Referring to fig. 7 and 8, when a user needs to inject liquid, the cover 50 is pushed horizontally in a direction away from the insertion hole 4154, so that the locking member 434 is driven by the movable member 433 to move, the first connecting portion 422 and the second connecting portion 421 are unlocked, for example, the locking groove 4344 on the claw 4343 is disengaged from the protrusion 4181, when the claw 4343 is aligned with the insertion hole 4154, the rotating shaft 436 moves to an end of the translation groove 4156 away from the insertion hole 4154, the cover 50 is in an unlocked position, and then the cover 50 is turned over, so that the liquid injection hole 402 is exposed and opened, and the user can perform a liquid injection operation; referring to fig. 6, when the user finishes pouring liquid and needs to close the liquid pouring port 402, the cover 50 is first turned over, so that the claws 4343 are received in the cavity 4153 through the insertion holes 4154, at this time, the cover 50 is in the unlocking position, and then the cover 50 is pushed horizontally toward the protrusions 4181, so that the locking grooves 4344 and the protrusions 4181 are engaged with each other, and the periphery of the insertion holes 4154 abuts against the claws 4343, thereby limiting the turning motion of the locking member 43 relative to the connecting assembly 40, that is, the cover 50 cannot be turned over relative to the connecting assembly 40, at this time, the cover 50 is in the locking position, the first connecting portion 422 and the second connecting portion 421 are locked, the cover 50 covers the connecting assembly 40, the liquid pouring port 402 is closed, and the user can suck.

In the present embodiment, when the cover 50 is in the locked position, on one hand, due to the abutting action of the elastic member 419 on the second connecting member 4345, and on the other hand, due to the engaging action of the engaging groove 4344 and the protrusion 4181, the cover 50 is always kept in the locked position, and the cover 50 is prevented from sliding to the unlocked position due to a small locking force. It is understood that in other embodiments, not shown, only one of the engaging structure of the locking groove 4344 and the protrusion 4181 and the elastic member 419 is required to be retained, and the cover 50 can be prevented from sliding freely.

In this embodiment, the atomizer 100 further includes a first locking component, and it is understood that the connecting component 40, the cover 50, the first locking component and the second locking component together form a liquid injection protection device. The first locking component includes a locking hole disposed on the cover 50 and a locking member capable of passing through the locking hole to be detachably connected to the connecting component 40. When one end of the locking member is inserted through the locking hole and connected to the connecting assembly 40, the moving stroke of the lid 50 is limited by the locking member, so that the pouring outlet 402 can be prevented from being opened by moving the lid 50.

Referring to fig. 2 and 9 again, in the present embodiment, the locking hole is a through hole 501 disposed on the movable member 433 of the cover 50, and the locking member is a cigarette holder 60 connected to the connecting member 40 after passing through the through hole 501. Specifically, the mouthpiece 60 is substantially a hollow cylindrical structure with openings at both ends, and one end of the mouthpiece 60 is inserted into the insertion hole 4152 of the stopper 415 after passing through the through hole 501. In this embodiment, the hole wall of the through hole 501 is convexly provided with the limiting protrusion 5011, the outer peripheral wall of the cigarette holder 60 is concavely provided with the limiting groove 601, and the limiting protrusion 5011 is movably clamped and embedded in the limiting groove 601, so that the situation that the cigarette holder 60 is lost due to separation of the cigarette holder 60 and the cover 50 is avoided. Specifically, when the mouthpiece 60 is pulled out until the limit protrusion 5011 abuts against one end of the limit groove 601, one end of the mouthpiece 60 is separated from the insertion hole 4152 and is accommodated in the through hole 501, at this time, the locking relationship between the connecting assembly 40 and the cover 50 is released, and the cover 50 can be pushed relative to the connecting assembly 40, and then the cover 50 is turned over, so that the liquid injection port 402 is exposed, and the user can perform the liquid injection operation. When the mouthpiece 60 is inserted inward until the limit protrusion 5011 abuts against the other end of the limit groove 601, the mouthpiece 60 is inserted into the insertion hole 4152, so that the connection assembly 40 and the cover 50 are locked, and the user can perform a smoking operation through the mouthpiece 60 but cannot perform a liquid injection operation. It is understood that in other embodiments not shown, the limiting protrusion 5011 may also be disposed convexly on the outer wall of the mouthpiece 60, and the limiting groove 601 is correspondingly disposed concavely on the hole wall of the through hole 501, which also can prevent the mouthpiece 60 from being lost.

Referring to fig. 2 again, in the present embodiment, the liquid injection protection device further includes a movable ring 403 rotatably sleeved outside the connection assembly 40, and the connection assembly 40 is hidden in the movable ring 403. Specifically, the movable ring 403 is rotatably sleeved outside the connecting seat 411, and the user is difficult to take off the connecting assembly 40 by holding the movable ring 403 so that the connecting assembly 40 rotates relative to the housing 10, thereby preventing the connecting assembly 40 from being detached, and preventing the occurrence of the situation that the children detach the connecting assembly 40 and then contact the tobacco juice in the liquid storage cavity 101. In a specific embodiment, the movable ring 403 completely shields the outer circumferential surface of the coupling seat 411, making it difficult for a user to apply force to the coupling seat 411. Only when the cover 50 is in the flip position relative to the connection assembly 40, the cover 50 can be well forced to remove the connection assembly 40, so as to replace the atomizing head 20.

It can be understood that, when injecting liquid, the user needs to unlock the first locking component between the cover 50 and the connecting assembly 40 first to separate the locking member from the locking hole, and then unlock the second locking component between the cover 50 and the connecting assembly 40 to separate the first connecting portion 422 from the second connecting portion 421, so that the liquid injection port 402 on the connecting assembly 40 can be opened by turning over the cover 50, and then the liquid injection operation can be performed. After the liquid injection operation is completed, the locking process is opposite to the unlocking process, and details are not described here.

It will be appreciated that in other embodiments not shown, only either of the first and second locking assemblies may be provided.

In the atomizer 100 according to the first embodiment of the present invention, the cover 50 can open the liquid injection port 402 by the operation of combining horizontal pushing and turning over only by releasing the locking relationship between the locking member and the connecting member 40 and the cover 50, so that the liquid injection port 402 is relatively complicated to open, and the liquid injection protection device has a child-proof function.

The electronic cigarette provided by the first embodiment of the present invention has all the technical features of the atomizer 100, and therefore has the same technical effects as the atomizer 100.

Example two

Referring to fig. 10 and 11, a second embodiment of the present invention provides an electronic cigarette, which includes an atomizer 200 and a power supply device (not shown) electrically connected to the atomizer 200. Compared with the electronic cigarette in the first embodiment, the differences are that: the connecting assembly 40 and the cover 50 of the atomizer 200 have different structures and different matching manners, and the housing 10, the atomizing head 20 and the base assembly 30 are the same as those of the first embodiment, and are not described herein again.

Referring to fig. 12 and 13, in the present embodiment, the connecting assembly 40 includes a connecting seat 411 and a pressing cover 416 covering the connecting seat 411. The smoke outlet 401 and the liquid injection port 402 are sequentially opened on the connecting seat 411 from the center of the connecting seat 411 to the outside along the radial direction of the connecting seat 411. The connecting seat 411 is disposed at an end of the housing 10 away from the base assembly 30, and a hollow connecting column 4111 is formed by downwardly protruding a surface of the connecting seat 411 away from the pressing cover 416. The connecting column 4111 is inserted into one end of the atomizing sleeve 21 away from the base assembly 30, and is used for fixing the connecting assembly 40 to the atomizing head 20 and allowing the smoke in the atomizing chamber 201 to flow. In addition, the connection assembly 40 further includes a sealing ring 418 disposed between the connection holder 411 and the liquid storage tube 20 for preventing the leakage of the smoke liquid.

The edge of one side of the pressing cover 416 is inwards sunken to form a U-shaped notch 4161 with one end opened, and the smoke outlet 401 and the liquid injection port 402 are both accommodated and exposed in the notch 4161. Specifically, the notch 4161 includes a connecting wall 4162 located on the side of the smoke outlet 401 away from the liquid injection port 403, and two side walls 4164 connected to opposite ends of the connecting wall 4162 and extending in the same direction. The surface of the connecting wall 4162 close to the connecting seat 411 is continuously recessed in a direction away from the smoke outlet 401 to form a groove 4166, so that a receiving gap with a certain height is formed between the pressing cover 416 and the connecting seat 411. Meanwhile, the surfaces of the two side walls 4164, which are close to the connecting wall 4162, at the end connected with the connecting wall 4162 are recessed in the direction away from each other to form a translation groove 4165, and the translation groove 4165 is communicated with the notch 4161 and the groove 4166. At this time, the two translational grooves 4165 and the groove 4166 are communicated to form a U-shaped groove surrounding the notch 4161 and having the same opening direction as the notch 4161.

When one end of the cover 50 is received and retained in the groove 4166, the cover 50 is in the locked position, and the cover 50 cannot be turned over relative to the connecting assembly 40. When the cover 50 is slid along the translating groove 4165 until the end of the cover 50 moves out of the groove 4166, the cover 50 is in the unlocked position and the cover 50 can be flipped over.

Specifically, the cover 50 includes a movable member 433 and a rotating shaft 436 protruding from opposite sides of one end of the movable member 433. The movable member 433 is substantially rectangular plate-shaped, and the shape thereof matches with the shape of the notch 4161. The through hole 501 is disposed on the movable member 433 in a penetrating manner and has a hole wall protruding from the surface of the movable member 433 away from the connecting base 411. When the cover 50 is in the locked position, the rotating shaft 436 is engaged with the groove 4166, and the wall of the through hole 501 abuts against the wall of the groove 4166, thereby preventing the cover 50 from being turned over around the rotating shaft 436. When the cover 50 is moved from the locked position to the unlocked position by an external force, the rotating shaft 436 moves out of the groove 4166 into the translating groove 4165, so that a space for the movable member 433 to turn over relative to the pressing cover 416 around the rotating shaft 436 is formed between the wall of the through hole 501 and the wall of the groove 4166. At this point, the cover 50 may be flipped over and opened relative to the attachment assembly 40 such that the pour spout 402 is exposed for easy operation by the user. And the cover body 50 can be relatively covered on the connecting component 40 after the liquid injection is finished, and then horizontally pushed from the unlocking position to the locking position. The movable part 433 can not be directly turned over when the electronic cigarette is in the locked position, and the interference between the movable part 433 and the pressing cover 416 needs to be relieved by horizontal pushing, so that the turning over of the movable part 433 can be realized, the cover body 50 is prevented from being opened in the using process of the electronic cigarette, and the electronic cigarette has a child protection function.

The cover 50 further includes a covering portion 432 disposed at an end of the movable member 433 opposite to the rotating shaft 436, the covering portion 432 extends to two sides relative to the movable member 433, and a width of the covering portion 432 is greater than a width of the notch 4161. In this embodiment, the covering portion 432 is a sector extending and spreading toward both sides relative to the movable member 433. Meanwhile, the bottom of the end of the pressing cover 416 remote from the connecting wall 4162 is provided with a locking groove 4163 communicating with the notch 4161, and the width of the locking groove 4163 is greater than that of the notch 4161, i.e., the locking groove 4163 and the notch 4161 form a stepped groove which is narrow at the top and wide at the bottom. Thus, when the cover 50 is pushed into the locking position relative to the connecting assembly 40, the locking portion 432 is received in the locking groove 4163 and abuts against the bottom wall of the locking groove 4163 to prevent the cover 50 from being pushed further, and on the other hand, the upper surface of the locking portion 432 and the upper groove wall of the locking groove 4163 abut against each other to further prevent the cover 50 from being turned over relative to the connecting assembly 40. When the cover 50 is pushed out of the unlocking position relative to the connecting assembly 40, the cover portion 432 is moved out of the locking groove 4163 through the opening of the locking groove 4163, so that the cover 50 can be turned over relative to the connecting assembly 40.

It will be appreciated that the locking groove 4163 forms a first connecting portion, the cover portion 432 forms a second connecting portion, and the first connecting portion and the second connecting portion together form a second locking assembly, such that when the cover body 50 is moved until the cover portion 432 is received in the locking groove 4163, the cover body 50 is locked; when the cover body 50 is moved to the state where the fitting portion 432 is separated from the locking groove 416, the cover body 50 is unlocked.

In a specific embodiment, the liquid inlet 402 is an arc-shaped opening surrounding part of the outer periphery of the smoke outlet 401, and the size of the liquid inlet 402 is increased while matching with the shape of the fan-shaped covering part 432, thereby facilitating the liquid injection operation.

In this embodiment, in order to ensure the sealing performance between the pressing cover 416 and the cover body 50, a sealing groove 4143 is formed around the smoke outlet 401 and the liquid injection port 402 on the connecting seat 411, and the connecting assembly 40 further includes a sealing gasket 45, where the sealing gasket 45 is accommodated in the sealing groove 4143 and hermetically surrounds the peripheries of the smoke outlet 401 and the liquid injection port 402.

Referring to fig. 14, in the present embodiment, the connection assembly 40 further includes a pin 417, and the pin 417 passes through the lower portion of the connection seat 411 and is fixed on the pressing cover 416, so as to fix the connection seat 411 and the pressing cover 416. It is understood that in other embodiments not shown, the fixing manner of the pressing cover 416 and the connecting seat 411 may be determined according to the requirement, or the two are integrally formed, and is not limited herein.

In addition, in order to prevent the liquid injection port 402 from being opened arbitrarily by a child when the child takes the atomizer 200, and then the child contacts the tobacco liquid in the liquid storage chamber 101, the atomizer 200 may further include a first locking component in addition to the second locking component, and the first locking component has the same structure and the same matching relationship as those in the first embodiment, and will not be described again here.

It will be appreciated that the connecting assembly 40, the cover 50, the first locking assembly and the second locking assembly together form a liquid injection protection device, and when one end of the locking member passes through the locking hole and is connected to the connecting assembly 40, the moving stroke of the cover 50 is limited by the locking member, so as to prevent the movable cover 50 from opening the liquid injection port 402.

It can be understood that, when the user injects the liquid, the first locking component between the cover 50 and the connecting component 40 needs to be released first to separate the locking piece from the locking hole, and then the second locking component between the cover 50 and the connecting component 40 needs to be released to separate the covering portion 432 from the locking groove 416, so that the liquid injection operation can be performed.

In the atomizer 200 according to the second embodiment of the present invention, the lid 50 can open the liquid inlet 402 by the operation of combining the horizontal pushing and the turning operation only by releasing the locking relationship between the locking member and the connecting member 40 and the lid 50, and thus the opening process of the liquid inlet 402 is complicated, and therefore, the atomizer has a child-proof function. Meanwhile, compared with the first embodiment, the atomizer 200 of the second embodiment has a simpler structure, thereby facilitating production.

The electronic cigarette provided by the second embodiment of the present invention has all the technical features of the atomizer 200, and therefore has the same technical effects as the atomizer 200.

EXAMPLE III

Referring to fig. 15 to 18, a third embodiment of the present invention provides an electronic cigarette, which includes an atomizer 300 and a power supply device (not shown) electrically connected to the atomizer 300. The atomizer 300 includes a housing 10, an atomizing head 20 accommodated in the housing 10, a base assembly 30 connected to one end of the housing 10, a connecting assembly 40 connected to the other end of the housing 10 opposite to the base assembly 30, and a cover 50 covering the connecting assembly 40, wherein a power supply device is detachably mounted on the base assembly 30 and electrically connected to the atomizing head 20, the housing 10 stores smoke liquid and supplies the smoke liquid to the atomizing head 20, and the atomizing head 20 heats the smoke liquid under the electric driving action of the power supply device to generate smoke for a user.

The structures of the housing 10, the atomizing head 20 and the base assembly 30 are the same as those of the first embodiment, and are not described herein again.

Referring to fig. 16, in the present embodiment, the connecting assembly 40 includes a connecting seat 411 connected to an upper end of the housing 10 and a vent 42 located in the housing 10 and connected to a lower end of the connecting seat 411.

The connecting base 411 is inserted into the upper end of the housing 10, the connecting base 411 is a hollow cylindrical structure with an opening at the upper end, and a connecting column 4111 for smoke to flow out is arranged at the center of the bottom of the connecting base 411. The upper end of the connecting column 4111 penetrates the bottom of the connecting seat 411, and the lower end of the connecting column 4111 extends downwards into the housing 10 along the axial direction of the atomizer 300. Two liquid injection ports 402 which are communicated with the liquid storage cavity 101 are formed in two opposite sides of the connecting column 4111 at the bottom of the connecting seat 411, and a user can inject cigarette liquid into the liquid storage cavity 101 through the liquid injection ports 402. It is understood that in other embodiments not shown, there may be one or more than two pour ports 402.

The air vent 42 is a hollow tubular structure with openings at two ends, the upper end of the air vent 42 is detachably connected with the connecting seat 411, and the lower end of the air vent 42 is detachably connected with the atomizing head 20. Specifically, the upper end of the ventilation piece 42 is tightly sleeved inside the connection column 4111, the lower end of the ventilation piece 42 is in threaded connection with the atomizing head 20, a smoke outlet channel 423 is formed in an inner cavity of the ventilation piece 42, and during use, smoke generated in the atomizing head 20 enters the mouth of a user through the smoke outlet channel 423.

It is understood that in other embodiments, which are not shown, the upper end of the vent 42 and the connection post 4111 may be connected by a screw connection, a snap connection, or the like, and the lower end of the vent 42 and the atomizing head 20 may be connected by a snap connection, a plug connection, or the like, which is not limited herein.

It is understood that in other embodiments not shown, the upper end of the vent piece 42 is closely sleeved outside the connection column 4111, and the connection relationship between the vent piece 42 and the connection column 4111 can also be realized.

It will be appreciated that in other embodiments not shown, the vent 42 may also be omitted, in which case the atomizing head 20 is removably connected directly to the connection post 4111.

Referring to fig. 16 again, the cover 50 is substantially a disc-shaped structure, and the edge of the cover 50 is hinged to the top of the connecting seat 411, so that the cover 50 can be turned over relative to the connecting seat 411, and the cover 50 can cover or open the upper end opening of the connecting seat 411, and further cover or open the liquid filling opening 402.

In order to prevent the liquid injection port 402 from being opened arbitrarily by a child when the child takes the atomizer 300, and then the child contacts the tobacco juice in the liquid storage chamber 101, the atomizer 300 further includes a first locking component, and the first locking component includes a locking hole formed in the cover body 50 and a locking member capable of passing through the locking hole and detachably connected to the connecting component 40. When one end of the locking member is inserted through the locking hole and connected to the connecting assembly 40, the moving stroke of the lid 50 is limited by the locking member, so that the pouring outlet 402 can be prevented from being opened by moving the lid 50.

In the present embodiment, the locking hole is a through hole 501 provided at the center of the cover 50, and the locking member is a mouthpiece 60 connected to the connection assembly 40 after passing through the through hole 501. Specifically, the mouthpiece 60 is substantially in a hollow tubular structure with openings at two ends, and after the lower end of the mouthpiece 60 penetrates through the through hole 501 of the cover 50, the lower end of the mouthpiece 60 is tightly sleeved inside the ventilation member 42, so as to realize the connection relationship between the mouthpiece 60 and the connection assembly 40. It is understood that in other embodiments not shown, when the upper end of the ventilation member 42 is tightly sleeved outside the connection column 4111, or when the ventilation member 42 is omitted, the lower end of the mouthpiece 60 is tightly sleeved inside the connection column 4111, so as to achieve the connection relationship between the mouthpiece 60 and the connection component 40. It will also be appreciated that in other embodiments not shown, the mouthpiece 60 may also be connected to the connection assembly 40 by a threaded connection, snap fit, or the like.

In the present embodiment, the outer diameter of the mouthpiece 60 is equal to the inner diameter of the through hole 501 of the cover 50, and specifically, the outer diameter of the portion where the mouthpiece 60 is fitted to the through hole 501 is equal to the inner diameter of the through hole 501. When the mouthpiece 60 is connected to the connecting component 40, since the outer diameter of the fitting portion of the mouthpiece 60 and the through hole 501 is equal to the inner diameter of the through hole 501, there is no movable space between the fitting positions of the mouthpiece 60 and the through hole 501, and the cover 50 cannot be turned over relative to the mouthpiece 60, and further, due to the connection relationship between the mouthpiece 60 and the connecting component 40, the cover 50 cannot be turned over together with the mouthpiece 60 relative to the connecting seat 411, and the cover 50 is locked.
