[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0038] See also Figure 1 , Figure 1 It is an overall schematic diagram of an electronic atomization device provided in one embodiment of the present application. The electronic atomization device 1 is used to atomize the atomization medium to form an aerosol for the user to inhale. The atomization medium can be a liquid matrix or a paste matrix, such as oils with added aroma components, liquid medicine, etc. The electronic atomization device 1 includes an atomizer 2 and a host 4 that are connected to each other. The atomizer 2 is used to store the liquid atomization matrix and atomize the liquid atomization matrix to form an aerosol that can be inhaled by the user. The atomizer 2 can be specifically used in different fields, such as medical atomization, agricultural spraying, and leisure inhalation. The host 4 is used to be electrically connected to the atomizer 2 and control the operation of the atomizer 2. Among them, the atomizer 2 and the host 4 can be an integral arrangement or a detachable connection, and are designed according to specific needs.

[0039] See also Figures 2 to 3 , Figure 2 It is an overall schematic diagram of an atomizer 2 provided in one embodiment of the present application; Figure 3 This is provided by an embodiment of the present application Figure 2 AA sectional view of the atomizer 2 shown. The atomizer 2 includes an atomizing tube 21, a liquid storage chamber 22, an atomizing assembly 23, a mounting seat 24, and a nozzle assembly 3. Among them, the liquid storage chamber 22 is used to store the atomizing medium. The atomizer 2 can be provided with a special liquid storage chamber 22, or a detachable liquid storage bottle can be used as the liquid storage chamber 22. The atomizing assembly 23 is used to atomize the atomizing medium to generate an aerosol. The atomizing tube 21 has a receiving chamber, and the atomizing assembly 23 is accommodated in the receiving chamber. An air outlet channel 211 is formed in the atomizing tube 21, and the atomizing assembly 23 has an atomizing channel 231 connected to the air outlet channel 211. The mounting seat 24 is used to be electrically connected to the main unit 4, and the mounting seat 24 has an air passage 241 connected to the main unit 4 and the atomizing channel 231. One end of the air outlet channel 211 is in fluid communication with the atomizing assembly 23. The nozzle assembly 3 is in fluid communication with the other end of the air outlet channel 211. Fluid connectivity refers to the interconnection between containers and channels, and the transmission of gas or liquid between containers and channels.

[0040] Specifically, the atomizer tube 21 has a relative assembly end 212 and an air outlet end 213. The air outlet end 213 is connected to the nozzle assembly 3 by interference fit. The air outlet end 213 is formed with an air outlet channel 211. The atomizer assembly 23 and the mounting seat 24 are accommodated in the assembly end 212. Among them, the atomizer assembly 23 includes a connecting tube 232 and an atomizer core 233 assembled in the connecting tube 232. The connecting tube 232 extends into the atomizer tube 21 and is matched with the air outlet channel 211. The connecting tube 232 has an atomizer channel 231 connected to the air outlet channel 211. Among them, a through hole is opened on the connecting tube 232, which is arranged toward the atomizer core 233 and is connected to the liquid storage chamber 22. When the liquid storage chamber 22 contains an atomizer medium, the atomizer medium enters the atomizer core 233 through the through hole, and the atomizer core 233 generates heat to atomize the atomizer medium, and generates an aerosol that flows from the atomizer channel 231 to the air outlet channel 211 for use by users. Optionally, taking the hollow cylindrical atomizing core 233 as an example, an atomizing cavity is formed inside. The atomizing core 233 includes a porous liquid-conducting liquid and a heating element, which can be a cotton core, a metal grid or a dense matrix.

[0041] like Figures 3 to 7 , Figure 4 is an overall schematic diagram of an atomizer with a nozzle cover in a first position provided by an embodiment of the present application, Figure 5 This is provided by an embodiment of the present application Figure 1 The AA cross-sectional view of the nozzle cover of the atomizer is shown in the second position. Figure 6 is an overall schematic diagram of a nozzle cover of an atomizer provided by an embodiment of the present application being located in a second position, Figure 7 2 is a cross-sectional schematic diagram of a nozzle cover of a nozzle assembly provided by an embodiment of the present application in a first position. Figure 3 or Figure 5The nozzle assembly 3 is used to be inserted into the user's mouth for the user to suck, and has the functions of dust prevention, reducing the volatilization of the atomized medium, etc. In one embodiment, the nozzle assembly 3 includes a nozzle seat body 31 and a nozzle cover body 32.

[0042] The nozzle seat 31 has an air guide channel 311, which is used to connect the air outlet channel 211 of the atomizer 2. The nozzle cover 32 is slidably connected to the nozzle seat 31 in the direction of the rotation axis M through the elastic member 33. It should be noted that the sliding connection means that the nozzle cover 32 and the nozzle seat 31 can slide or rotate relative to each other, and during the relative sliding or rotating process, at least part of the two always keep in contact, which is different from the existing plug-in type silicone sealing plug sealing method of the nozzle.

[0043] See also Figure 3 and Figure 4 When the nozzle cover 32 is in the first position relative to the nozzle base 31, the air guide channel 311 is not connected to the outside through the nozzle cover 32. Figure 5 and Figure 6 When the nozzle cover 32 is in the second position relative to the nozzle base 31, the air guide channel 311 is connected to the outside through the nozzle cover 32, so that the user can inhale the aerosol from the air outlet channel 211 through the air guide channel 311 through the nozzle assembly 3. In this way, the user can set the nozzle cover 32 to the first position or the second position as needed to realize the switch function of the air guide channel 311. After use, the nozzle cover 32 is set to the first position, and the air guide channel 311 is closed, which plays a child-proof role and effectively reduces the risk of the atomized medium in the atomizer 2 volatilizing through the air guide channel 311 and being contaminated. At the same time, since the nozzle cover 32 and the nozzle base 31 are always connected together, the nozzle cover 32 is not easy to be lost and is more convenient to use.

[0044] In one embodiment, see Figure 3 and Figure 5 The nozzle cover 32 and the nozzle base 31 are slidably connected in the direction of the rotation axis M by the elastic member 33, so that the nozzle cover 32 and the nozzle base 31 have a certain movable space in the direction of the rotation axis M, so that the first limiting mechanism 322 and the second limiting mechanism 312 can cooperate to lock or unlock. Figure 7, when the nozzle cover 32 rotates to the first position relative to the nozzle seat 31, the air guide channel 311 is not connected to the outside world through the nozzle cover 32; the elastic member 33 drives the nozzle cover 32 to slide relative to the nozzle seat 31 along the direction of the rotation axis M to achieve the locking of the nozzle cover 32 and the nozzle seat 31. An unlocking force is applied to the nozzle cover 32 along the direction of the rotation axis M, and when the nozzle cover 32 slides in the opposite direction along the direction of the rotation axis M relative to the nozzle seat 31, the nozzle cover 32 and the nozzle seat 31 are unlocked; wherein, when the nozzle cover 32 is in the second position relative to the nozzle seat 31, the air guide channel 311 is connected to the outside world through the nozzle cover 32. In this way, after the user uses the electronic atomization device 1, the nozzle cover 32 is rotated so that the nozzle cover 32 is in the first position relative to the nozzle seat 31, and the nozzle cover 32 and the nozzle seat 31 are automatically locked through the elastic member 33. When the user needs to use the electronic atomization device 1, it is necessary to apply an unlocking force in the direction of the rotation axis M, that is, to press down to unlock. By rotating the nozzle cover 32, the switch function of the air guide channel 311 is realized. After the atomizer 2 is not in use, the nozzle cover 32 is rotated to the closed state of the air guide channel 311, so that the inside of the atomizer 2 is isolated from the outside air, reducing the dust pollution inside the atomizer 2, the loss of the atomized medium and the odor emission. Of course, the locking method can also be an elastic hook with a card block or a card slot, which requires force to unlock, but does not need to be pressed down.

[0045] See also Figure 3 In one embodiment, the first end of the air guide channel 311 has an air inlet 3111, and the second end has an air outlet 3112. The nozzle cover 32 has a first avoidance hole 321, and the nozzle cover 32 is rotationally connected to the nozzle seat 31, that is, the nozzle cover 32 and the nozzle seat 31 can rotate relative to each other. In one embodiment, the nozzle cover 32 can be sleeved on the outside of the nozzle seat 31, and is circumferentially rotationally connected to the nozzle seat 31 through a thread. In another embodiment, the nozzle cover 32 and the nozzle seat 31 can also be rotationally connected through other adapters. For example, the adapter is fixed to the nozzle seat 31, and the nozzle cover 32 is rotationally connected to the adapter, thereby realizing the relative rotation between the nozzle cover 32 and the nozzle seat 31. Alternatively, the rotational connection between the two is achieved through an elastic member as described below, and details can be seen below.

[0046] See also Figure 3 and Figure 4 When the rotating nozzle cover 32 is in the first position relative to the nozzle base 31, the air outlet 3112 is not in fluid communication with the first avoidance hole 321, so that the air guide channel 311 is not in fluid communication with the outside through the nozzle cover 32. Figure 5 and Figure 6When the rotating nozzle cover 32 is in the second position relative to the nozzle base 31, the air outlet 3112 is in fluid communication with the first avoidance hole 321, so that the air guide channel 311 is in communication with the outside through the nozzle cover 32. In this way, the user can set the nozzle cover 32 to the first position or the second position as needed to realize the switch function of the air guide channel 311. After use, the nozzle cover 32 is set to the first position, and the air guide channel 311 is closed, which plays a child-proof role and effectively reduces the problem of volatilization and contamination of the atomized medium in the atomizer 2 through the air guide channel 311.

[0047] For details, see Figure 7 In one embodiment, the nozzle cover 32 has a first limiting mechanism 322, and the nozzle seat 31 has a second limiting mechanism 312. When the nozzle cover 32 is in the first position relative to the nozzle seat 31, the first limiting mechanism 322 and the second limiting mechanism 312 cooperate to lock the nozzle cover 32 and the nozzle seat 31. It should be noted that locking refers to limiting the nozzle cover 32 from switching from the first position to the second position relative to the nozzle seat 31, that is, being locked, limiting the circumferential rotation of the nozzle cover 32, playing a child-proof function, and the air guide channel 311 is closed. When the nozzle cover 32 switches from the first position to the second position relative to the nozzle seat 31, a certain unlocking force needs to be applied to enable the nozzle cover 32 to switch from the first position to the second position relative to the nozzle seat 31, that is, being unlocked. The nozzle cover 32 can rotate circumferentially, and the air guide channel 311 is opened, and the user can use it. In this way, after using the electronic atomization device 1, the user rotates the nozzle cover 32 so that the nozzle cover 32 is in the first position relative to the nozzle base 31. The nozzle cover 32 and the nozzle base 31 are in a locked state in the first position, which effectively prevents the nozzle cover 32 of the electronic atomization device 1 from being accidentally opened by the user or children, and effectively reduces the problem of volatilization and contamination of the atomizer medium in the atomizer 2 through the air guide channel 311.

[0048] In one embodiment, see Figure 3 and Figure 7The nozzle cover 32 includes an annular side wall 323 and a top wall 324. The inner side of the annular side wall 323 of the nozzle cover 32 has a first limiting mechanism 322, and the top wall 324 of the nozzle cover 32 has a first avoidance hole 321. The nozzle seat 31 includes an annular side wall 313 and a top wall 314. The outer side of the annular side wall 313 of the nozzle seat 31 has a second limiting mechanism 312. Part of the annular side wall 323 of the nozzle cover 32 is sleeved on the outer side of the nozzle seat 31, and the elastic member 33 is an elastic seal disposed between the top wall 324 of the nozzle cover 32 and the top wall 314 of the nozzle seat 31. Among them, the elastic seal can not only make the nozzle cover 32 and the nozzle seat 31 slidably connected in the direction of the rotation axis M, but also when the nozzle cover 32 is in the first position relative to the nozzle seat 31, the elastic seal is also used to block the first avoidance hole 321. The elastic sealing member can better seal the first avoidance hole 321 , so that the air guide channel 311 is not connected to the outside through the first avoidance hole 321 .

[0049] The elastic member 33 may also be a spring, but the spring has no sealing function. For example, the air outlet 3112 and the first avoidance hole 321 may both be arranged on the side wall, that is, the air outlet 3112 is arranged on the side wall of the air guide channel 311, and the first avoidance hole 321 is arranged on the annular side wall 323 of the nozzle cover 32. The spring is arranged between the top wall 324 of the nozzle cover 32 and the top wall of the air guide channel 311, and the air outlet 3112 and the first avoidance hole 321 are configured such that when an unlocking force is applied to the nozzle cover 32 in the direction of the rotation axis M, that is, pressing downward, the air outlet 3112 and the first avoidance hole 321 are fluidically connected and can be used by the user. When the unlocking force disappears, the nozzle cover 32 is reset by the spring, so that the air outlet 3112 and the first avoidance hole 321 are misaligned, achieving a closed effect.

[0050] In one embodiment, see Figure 7 The inner side surface of the annular side wall 323 of the nozzle cover 32 has a hook 3231 as a first limiting mechanism 322, and the outer side surface of the annular side wall 313 of the nozzle seat 31 has an annular flange 315, and the surface of the annular flange 315 away from the elastic member 33 has a block 316 as a second limiting mechanism 312. The hook 3231 is located on the side of the annular flange 315 away from the elastic member 33, and fits with the surface of the annular flange 315, and can slide along the circumferential direction of the annular flange 315. Among them, the block 316 is specifically located in the sliding path of the hook 3231, and is used to stop the rotation process of the hook 3231, so that the nozzle cover 32 is in the first position or the second position relative to the nozzle seat 31. Among them, the mutual cooperation between the annular flange 315 and the hook 3231 can further prevent the nozzle cover 32 from falling off the nozzle seat 31.

[0051] In a specific embodiment, the number of the hooks 3231 and the block 316 are both two, and the two hooks 3231 are relatively arranged on the two sides of the nozzle cover 32, and the two blocks 316 are relatively arranged on the two sides of the nozzle base 31. Along the rotation direction of the nozzle cover 32, one side of the block 316 is an inclined surface. During the process of the nozzle cover 32 rotating from the second position to the first position, the hook 3231 slides from one side of the block 316 to the other side along the inclined surface. At this time, the block 316 blocks the rotation process of the hook 3231 in the opposite direction, so that it remains in the first position. During the sliding process along the inclined surface, the nozzle cover 32 gradually squeezes the elastic seal. After sliding to the other side of the block 316, the elastic seal stretches, so that the hook 3231 is stuck by the other side of the block 316. Preferably, the other side of the block 316 is substantially parallel to the direction of the rotation axis M.

[0052] It can be understood that when the nozzle cover 32 needs to be moved from the first position to the second position, the nozzle cover 32 can be pressed downward so that the hook 3231 can pass over the block 316, so that the hook 3231 can rotate in the opposite direction to the second position, thereby achieving fluid communication between the air outlet 3112 and the first avoidance hole 321 for use by the user.

[0053] In one embodiment, see Figure 7The nozzle assembly 3 also includes a sealing sleeve 34, which is sleeved between the nozzle cover body 32 and the nozzle seat body 31, and the sealing sleeve 34 has a second avoidance hole 341. The sealing sleeve 34 is used to seal the gap between the nozzle cover body 32 and the nozzle seat body 31, and the second avoidance hole 341 is used to expose the air outlet 3112. Specifically, the sealing sleeve 34 includes an elastic sealing member. That is, the sealing sleeve 34 can not only make the nozzle cover body 32 and the nozzle seat body 31 slidingly connected in the direction of the rotation axis M, but also when the nozzle cover body 32 is in the first position relative to the nozzle seat body 31, the sealing sleeve 34 is also used to block the first avoidance hole 321. When the nozzle cover body 32 is in the second position relative to the nozzle seat body 31, the air outlet 3112 of the air guide channel 311 is fluidly connected to the first avoidance hole 321 through the second avoidance hole 341. The air outlet 3112 of the air guide channel 311 is in fluid communication with the first avoidance hole 321 through the second avoidance hole 341 and the internal space of the nozzle cover 32 in sequence. In this way, the elastic seal provides support between the nozzle cover 32 and the nozzle seat 31. After applying an unlocking force to the nozzle cover 32 in the direction of the rotation axis M, the elastic seal stretches, so that the hook 3231 of the nozzle cover 32 is stuck by the other side of the block 316 of the nozzle seat 31. This effectively prevents the nozzle cover 32 of the electronic atomization device 1 from being accidentally opened by the user or a child, and effectively reduces the problem of volatilization and contamination of the atomizer medium in the atomizer 2 through the air guide channel 311. At the same time, the elastic seal can seal the gap between the nozzle cover body 32 and the nozzle base body 31, so that the aerosol generated by the atomizer 2 can only flow out through the air outlet 3112 of the air guide channel 311 via the second avoidance hole 341 and part of the internal space of the nozzle cover body 32 and the first avoidance hole 321 for the user to inhale.

[0054] In one embodiment, the air outlet 3112 extends from the top wall 314 of the nozzle seat 31 to the side wall. That is, the top wall 314 of the nozzle seat 31 has a notch, and the connection between the top wall 314 of the nozzle seat 31 and the side wall of the nozzle seat 31 also has a notch, and the two notches are connected to form the air outlet 3112. In this way, the air outlet 3112 has a larger airflow throughput, reducing the risk of the air outlet 3112 being blocked by stains. At the same time, the air outlet channel (not marked in the figure) formed by the nozzle seat 31, the elastic member 33, and the nozzle cover body 32 has a tortuous path, that is, the air outlet channel is non-straight, so that the user reduces the inhalation of condensate. The sealing sleeve 34 includes an annular side wall 342 and a top wall 343. The top wall 343 of the sealing sleeve 34 serves as an elastic sealing member, and the annular side wall 342 of the sealing sleeve 34 is sleeved on the outer side of the top of the nozzle seat 31. The top of the annular side wall 342 of the sealing sleeve 34 has a first sealing convex ring 3421, and the bottom has a second sealing convex ring 3422, so as to seal the gap between the nozzle cover 32 and the nozzle seat 31. When the nozzle cover 32 is in the first position relative to the nozzle seat 31, the air outlet 3112 is in fluid communication with the internal space of the nozzle cover 32 and is not in fluid communication with the first avoidance hole 321. When the nozzle cover 32 is in the second position relative to the nozzle seat 31, the air outlet 3112 is in fluid communication with the first avoidance hole 321 through the second avoidance hole 341 and the internal space of the nozzle cover 32 in sequence.

[0055] In one embodiment, see Figure 7 and Figure 8 , Figure 8 Schematic diagram of the nozzle cover of the nozzle assembly provided in one embodiment of the present application. The nozzle assembly 3 also includes a third limiting mechanism 325, which is provided on the inner wall surface of the nozzle cover 32 and is located in the rotation path of the elastic member 33. The nozzle cover 32 and the nozzle seat 31 are slidably connected in the direction of the rotation axis M through the elastic member 33. The third limiting mechanism 325 is used to prevent the nozzle cover 32 from infinitely rotating relative to the nozzle seat 31. When the nozzle cover 32 rotates to the first position relative to the nozzle seat 31, the elastic member 33, the first limiting mechanism 322, the second limiting mechanism 312 and the third limiting mechanism 325 cooperate to lock the nozzle cover 32 and the nozzle seat 31. In one embodiment, the third limiting mechanism 325 is a baffle formed on the nozzle cover 32. During the process of the nozzle cover body 32 rotating from the second position to the first position, the baffle rotates from one side of the side wall of the nozzle seat body 31 to the other side of the side wall of the nozzle seat body 31, and the baffle is blocked by the opening of the side wall of the nozzle seat body 31 to limit the nozzle cover body 32 to be positioned in the first position, preventing the nozzle cover body 32 from continuing to rotate.

[0056] The present application provides a nozzle assembly 3, which includes a nozzle seat 31 and a nozzle cover 32. The nozzle seat 31 has an air guide channel 311, which is used to connect to the air outlet channel 211 of the atomizer 2. The nozzle cover 32 and the nozzle seat 31 are slidably connected in the direction M of the rotation axis through an elastic member 33; the nozzle cover 32 has a first limiting mechanism 322, and the nozzle seat 31 has a second limiting mechanism 312; when the nozzle cover 32 is in the first position relative to the nozzle seat 31, the air guide channel 311 is not connected to the outside through the nozzle cover 32; the elastic member 33 drives the nozzle cover 32 to move in a direction M of the rotation axis. The nozzle cover 32 slides relative to the nozzle seat 31 along the direction M of the rotation axis, and the nozzle cover 32 and the nozzle seat 31 are locked by the first limiting mechanism 322 and the second limiting mechanism 312; when the nozzle cover 32 slides in the opposite direction along the direction M of the rotation axis relative to the nozzle seat 31, the nozzle cover 32 and the nozzle seat 31 are unlocked; wherein, when the nozzle cover 32 is in the second position relative to the nozzle seat 31, the air guide channel 311 is connected to the outside through the nozzle cover 32. In this way, the user can set the nozzle cover 32 to the first position or the second position as needed to realize the switch function of the air guide channel 311. After use, the nozzle cover 32 is set to the first position, and the air guide channel 311 is closed, which effectively reduces the risk of the atomized medium in the atomizer 2 volatilizing and being contaminated through the air guide channel 311. At the same time, since the nozzle cover 32 and the nozzle seat 31 are always connected together, the nozzle cover 32 is not easy to be lost and is more convenient to use.

[0057] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
