[0032] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Currently, most electronic atomizing devices can be used directly after unpacking by removing the silicone stopper from the mouthpiece. This silicone stopper is designed to prevent leakage; if it is lost after removal, leakage may occur when the mouthpiece is placed upside down. Furthermore, since most electronic atomizing devices lack child locks, children could accidentally inhale and cause problems.

[0036] This application provides an electronic atomizing device to solve the above-mentioned technical problems.

[0037] like Figures 1-10 As shown, the electronic atomizing device proposed in the embodiments of this application includes: a housing 1, the housing 1 having a first channel 2 inside, and a first opening 3 communicating with the first channel 2 on the housing 1; a mouthpiece, movably connected to the first opening 3, the mouthpiece having an axially penetrating second channel 4; and a blocking part 5 located between the first channel 2 and the second channel 4; the mouthpiece has a first relative position and a second relative position relative to the housing 1. When the mouthpiece is in the first relative position, the first channel 2 and the second channel 4 are connected. When the mouthpiece is in the second relative position, the blocking part 5 blocks the radial section of the first channel 2 to block the first channel 2 from the second channel 4.

[0038] In one embodiment, the suction nozzle can be fixedly connected to the first opening 3 and can be removed from the first opening 3; for example, refer to... Figure 3 The nozzle is inserted into the second channel 4 via a plug-in connection, thereby fixing the nozzle relative to the first opening 3. The two are held in place by an interference fit. Thus, the fixed connection position is the first position mentioned above, and the removal position is the second position.

[0039] In one embodiment, the nozzle cannot be removed from the first opening 3, but can slide relative to the first opening 3. Depending on the sliding position, the nozzle and the housing 1 form the first position and the second position described above.

[0040] The housing 1 is used to carry and install the required components. The housing 1 has an atomization space and a storage space. The atomization space is used to atomize the aerosol generation matrix to form an aerosol. The required atomization components are installed in the space. The storage space is used to install devices such as nozzles. There is a first channel 2 between the storage space and the atomization space, which connects the two. The storage space penetrates the housing 1 and forms a first opening 3 on the housing 1 to connect the storage space with the outside.

[0041] The mouthpiece is used to draw in aerosols that are heated and atomized into droplets within the atomization space. The mouthpiece has a second channel 4 and is movably connected to the first opening 3. When the user needs to inhale, the aerosols that are heated and atomized into droplets pass through the first channel 2 and the second channel 4 in sequence before entering the user's mouth.

[0042] The blocking part 5 is located within the storage space and serves as a barrier. When the mouthpiece is in the second relative position, the first channel 2 and the second channel 4 are located on both sides of the blocking part 5, so that the blocking part 5 blocks the connection between the first channel 2 and the second channel 4, making it impossible to inhale. When the mouthpiece is in the first relative position, the first channel 2 and the second channel 4 are connected, and the user can inhale. This structural design achieves the effect of a child lock, effectively preventing children from accidentally inhaling the device. In addition, the blocking part 5 can also effectively prevent the mouthpiece of the disposable electronic cigarette from leaking oil when it is placed upside down.

[0043] like Figures 1-10As shown, in some embodiments, at least a portion of the blocking portion 5 is movable along a first direction A to change the occlusion range of the radial cross-section of the first channel 2; wherein, the suction nozzle abuts against the movable portion of the blocking portion 5 to move it along the first direction A to expose at least a portion of the radial cross-section of the first channel 2, such that the suction nozzle is in a first relative position; the suction nozzle disengages from the movable portion of the blocking portion 5 to move it in the opposite direction of the first direction A to block the radial cross-section of the first channel 2, such that the suction nozzle is in a second relative position; the first direction A is the direction from the second channel 4 to the first channel 2.

[0044] The blocking part 5 works in conjunction with the suction nozzle. During the movement of the suction nozzle, at least part of the movable blocking part 5 moves with the movement of the suction nozzle to block the connection between the first channel 2 and the second channel 4, or to release the blocking part 5 from blocking the connection between the first channel 2 and the second channel 4.

[0045] like Figures 2-3 , Figure 4 Figure 5 as well as Figure 7 As shown, in some embodiments, the barrier portion 5 includes: an elastic connecting piece, the connecting piece being disposed corresponding to the radial cross section of the first channel 2, and the circumferential edges of the connecting piece being connected to the inner wall of the first channel 2; the connecting piece having an abutting area, and the connecting piece having at least one dividing line 6, the dividing line 6 dividing the abutting area radially to form a petal-like structure in the abutting area.

[0046] This application provides an embodiment of a blocking part 5, wherein the blocking part 5 includes a flexible connecting piece located within and filling the storage space. An abutment area is located above one end of the first channel 2, and a dividing line 6 divides the abutment area. When the mouthpiece is in a second relative position, the abutment area of ​​the connecting piece blocks the first channel 2, preventing communication between the first channel 2 and the second channel 4. When the mouthpiece is in the first relative position, the second channel 4 of the mouthpiece passes through the dividing line 6 through the abutment area and communicates with the first channel 2. At this time, the user can achieve the effect of sucking through the mouthpiece. The flexible connecting piece, this structural design, allows the connecting piece to reset when the mouthpiece is in the second relative position and continue to block the first channel 2 through the abutment area.

[0047] In addition, when the suction nozzle opens the blocking part 5, the inner wall of the blocking part 5 in contact with the suction nozzle forms a gear-shaped edge structure. This structure design can effectively prevent the formation of oil film, that is, prevent the problem of oil suction.

[0048] like Figures 1-4 , Figure 6 as well as Figures 8-9As shown, in some embodiments, the suction nozzle has a suction nozzle body 7 and a suction nozzle inner tube 8. The suction nozzle body 7 has a central through hole. The suction nozzle inner tube 8 is connected to one end of the suction nozzle body 7 and communicates with the central through hole to form a first channel 2 on the inside. A section of the suction nozzle inner tube 8 near the second channel 4 is divided into a plurality of spaced partitions 9 in the circumferential direction. The tops of the plurality of partitions 9 are used to abut against the contact area.

[0049] This application provides an embodiment of a suction nozzle, wherein the suction nozzle includes a suction nozzle body 7 and a suction nozzle inner tube 8. The suction nozzle body 7 has a second channel 4 and a suction nozzle inner tube 8. The second channel 4 is located above the suction nozzle inner tube 8 and cooperates with the suction nozzle inner tube 8 to pass through the suction nozzle body 7.

[0050] Multiple baffles 9 are disposed on the nozzle body 7 and surround the inner tube 8 of the nozzle. The tops of the multiple baffles 9 are used to abut the contact area. The baffles 9 and the nozzle body 7 are made into an integral structure by integral processing and casting.

[0051] like Figures 2-3 , Figure 6 as well as Figure 8 As shown, in some embodiments, the mouthpiece also has a mouthpiece outer tube 10, which is sleeved on the outside of the mouthpiece inner tube 8 and connected to the mouthpiece body 7 as a whole. The electronic atomizing device also includes a liquid suction element 11, which is filled between the mouthpiece outer tube 10 and the mouthpiece inner tube 8.

[0052] The outer tube 10 of the suction nozzle and the body 7 are integrally formed by casting, which improves the overall structural strength of the device. There is a gap between the outer tube 10 of the suction nozzle and the partition 9, and the liquid suction element 11 fills the gap. There is a certain interval between adjacent partitions 9, and the space enclosed by multiple partitions 9 can be entered into the space enclosed by the outer tube 10 of the suction nozzle through the interval.

[0053] The liquid suction component 11 can adsorb the un-atomized aerosol matrix that enters the space enclosed by multiple partitions 9 through the first channel 2, thereby solving the problem of oil film easily forming inside the suction nozzle.

[0054] like Figures 1-4 , Figure 6 as well as Figure 8As shown, in some embodiments, the tube 15 is disposed on the first opening 3, and a first limiting groove 12 and a second limiting groove 13 are provided on the inner sidewall of the tube 15. The first limiting groove 12 and the second limiting groove 13 are arranged at intervals along the first direction A. A protrusion 14 is movably provided on the outer wall of the suction nozzle outer tube 10. The protrusion 14 is adapted to the first limiting groove 12 and the second limiting groove 13, and the protrusion 14 can reciprocate along the radial direction of the suction nozzle. The suction nozzle outer tube 10 is inserted into the tube 15, and the protrusion 14 is embedded in the first limiting groove 12 so that the suction nozzle has a first relative position relative to the housing 1. The protrusion 14 is embedded in the second limiting groove 13 so that the suction nozzle has a second relative position relative to the housing 1.

[0055] In this application, the suction nozzle and the first opening 3 are connected by a tube 15, that is, the tube 15 is fitted onto the first opening 3, and the outer tube 10 of the suction nozzle is inserted into the tube 15. The tube 15 is provided with a first limiting groove 12 and a second limiting groove 13. The outer tube 10 of the suction nozzle is provided with a protrusion 14. The first limiting groove 12 is located above the second limiting groove 13. When the protrusion 14 is embedded in the first limiting groove 12, the suction nozzle and the housing 1 have a first relative position. When the protrusion 14 is embedded in the second limiting groove 13, the suction nozzle and the housing 1 have a second relative position.

[0056] The outer tube 10 of the suction nozzle and the protrusion 14 are made into an integral structure by integral casting. The tube 15 and the first opening 3 can be connected in a detachable manner or in a fixed manner, such as bolt connection, adhesive, snap-fit, etc.

[0057] like Figures 2-3 as well as Figure 9 As shown, in some embodiments, the inner side of the end face of the outer tube 10 of the suction nozzle facing away from the body 7 has a guide angle 16, and the first sealing member 104 has a guide slope that cooperates with the guide angle 16. The guide angle 16 can play a guiding role. This structural design can facilitate pressing the outer tube 10 of the suction nozzle between the connecting piece and the first channel 2 when pressed down, thereby achieving the effect of fixing the suction nozzle.

[0058] like Figures 1-5 as well as Figure 7 As shown, in some embodiments, the housing 1 includes: a first seal 104, a second seal 102, and a liquid storage cup 103; the liquid storage cup 103 has a liquid storage cavity inside, an atomizing core body is disposed in the liquid storage cavity and a first channel 2 is formed therein, the two ends of the liquid storage cup 103 are sealed with the first seal 104 and the second seal 102, the first seal 104 has a connecting port, the connecting port is connected to the first channel 2, the blocking part 5 is located on the first seal 104, and the contact area is opposite to the connecting port.

[0059] This application provides a specific embodiment of the housing, namely, the housing includes a second sealing member 102, a liquid storage cup 103, and a first sealing member 104 arranged in sequence. The first sealing member 104 and the second sealing member 102 are used to seal the liquid storage chamber in the liquid storage cup 103. An atomizing core body is installed in the liquid storage chamber. The atomizing core body includes a power supply component, a heating component, and an atomization component for aerosol generation. The power supply component provides electrical energy to the heating component to support its operation. The heating component heats the aerosol generation component to atomize it. The aerosol generation component turns into vapor after being heated. The aerosol generation component typically contains components such as nicotine, fragrance, glycerin, and propylene glycol. These components are atomized into aerosol droplets during the heating process for the user to inhale. The power supply component, heating component, and atomization component for aerosol generation are connected in a conventional manner within the liquid storage chamber. The specific connection method is known to those skilled in the art and will not be described in detail here.

[0060] The liquid storage chamber has a first channel 2, and the first sealing member 104 has a connecting port that is connected to the first channel 2. The blocking part 5 is located on the first sealing member 104, and the contact area is opposite to the connecting port. This structural design makes it easy for the device to form a child lock structure.

[0061] like Figure 10 As shown, in some embodiments, the barrier portion 5 includes: a first plate 51 and a second plate 52 arranged sequentially along any radial direction of the first channel 23. The side of the first plate 51 facing away from the second plate 52 and the side of the second plate facing away from the first plate 51 are both rotatably connected to the inner wall of the first channel 23. The side of the first plate 51 facing the second plate 52 and the side of the second plate 52 facing the first plate 51 can be connected to each other.

[0062] The barrier portion 5 further includes: a first elastic member 53, wherein the first plate 51 and the inner wall of the first channel 23 are provided with a first elastic member 53 for providing a force to the first plate 51 in the opposite direction of the first direction A; and a second elastic member 54, wherein the second plate 52 and the inner wall of the first channel 23 are provided with a second elastic member 54 for providing a force to the second plate 52 in the opposite direction of the first direction A.

[0063] This application provides another embodiment of the barrier portion 5, namely, the barrier portion 5 includes: a first plate 51, a second plate 52, a first elastic member 53, and a second elastic member 54. The first plate 51 and the second plate 52 are arranged sequentially in the storage space. The first plate 51 is rotatably connected to the inner wall of the storage space, and the second plate 52 is rotatably connected to the inner wall of the storage space. The first elastic member 53 is disposed between the first plate 51 and the inner wall of the storage space, and the second elastic member 54 is disposed between the second plate 52 and the inner wall of the storage space. The side of the first plate 51 away from the rotatable side extends toward the direction where the second plate 52 is located, and the side of the second plate 52 away from the rotatable side extends toward the direction where the first plate 51 is located. One side of the first plate 51 and the second plate 52 are connected... The two sides of the nozzle abut against each other to block the connection between the first channel 2 and the second channel 4. When the nozzle moves in the direction of the first channel 2, it abuts against the junction of the first plate 51 and the second plate 52, so that the first plate 51 and the second plate 52 move away from each other. At this time, the first elastic element 53 and the second elastic element 54 both undergo elastic deformation. After the second channel 4 is connected to the first channel 2, the user can suck. After sucking, the user pulls the nozzle to separate the second channel 4 from the first channel 2. At this time, the first elastic element 53 provides a rebound force to the first plate 51 to reset the first plate 51, and the second elastic element 54 provides a rebound force to the second plate 52 to reset the second plate 52, thereby achieving the effect of blocking the connection between the first channel 2 and the second channel 4.
