[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the related art, the oil cup and suction nozzle of the electronic atomization device are usually manufactured and transported separately. Before use, the suction nozzle and the oil cup need to be assembled so that the liquid injection plug of the suction nozzle can be inserted into the injection part of the oil cup, thereby injecting the atomized medium into the liquid storage cavity of the oil cup through the injection part. However, on the one hand, during the assembly process, the suction nozzle and the oil cup are prone to misalignment and poor sealing, which can lead to oil leakage. On the other hand, in order to make the injection smooth, the injection part of the oil cup is usually set as a through hole, and the injection part connects the liquid storage cavity to the atmosphere. During the separate transportation of the oil cup, the liquid storage cavity is easily contaminated, affecting the taste of the user when using the electronic atomization device.

[0030] Based on this, the first aspect of the present application provides an electronic atomization device 100, in which the nozzle 10 of the electronic atomization device 100 is fixedly connected to the oil cup 20, and the position change of the sealing member 30 can be used to achieve smooth liquid injection. Figures 1 to 4The electronic atomization device 100 includes a nozzle 10, an oil cup 20 and a sealing member 30. An air suction chamber 14 having an open end 140 is formed in the nozzle 10. A movable member 40 is also provided in the nozzle 10. The oil cup 20 is arranged at one end of the nozzle 10. The oil cup 20 has a liquid storage chamber 21. The liquid storage chamber 21 has a liquid storage opening 210 facing the nozzle 10. The sealing member 30 is arranged at the liquid storage opening 210. The sealing member 30 is provided with an injection portion 31. The injection portion 31 is used to inject atomizing medium into the liquid storage chamber 21. At least one of the sealing member 30 and the oil cup 20 forms an exhaust structure. The movable member 40 can drive the sealing member 30 to switch from the oil filling position to the sealing position. When the sealing member 30 is in the oil filling position (such as Figure 1 As shown), the exhaust structure can connect the liquid storage chamber 21 with the suction chamber 14 or the outside world; when the sealing member 30 is in the sealing position (as shown Figure 3 As shown), the exhaust structure is blocked from communicating with the liquid storage chamber 21 , and the sealing member 30 moves to seal the liquid storage opening 210 .

[0031] By setting the sealing member 30 to have two states, namely, the oil filling position and the sealing position, and being able to switch from the oil filling position to the sealing position, when the sealing member 30 is in the oil filling position, the liquid storage chamber 21 can be connected to the outside through exhaust. During the process of injecting liquid into the liquid storage chamber 21, the air in the liquid storage chamber 21 can be discharged through the exhaust structure and the suction chamber 14 of the suction nozzle 10 (see Figure 2 , Figure 2The dotted line in the figure shows the path for the air in the liquid storage chamber 21 to be discharged, and the dotted line shows the path for the atomized medium to be injected during the injection process), so as to facilitate the atomized medium to be injected more smoothly and improve the injection efficiency. At the same time, during the injection process, the air pressure in the liquid storage chamber 21 can be prevented from increasing, so as to avoid the problem that the air in the liquid storage chamber 21 cannot be discharged, resulting in poor injection, or even the problem that the atomized medium leaks out of the matching gap between the liquid storage chamber 21 and the surrounding components due to the increase in the internal pressure of the liquid storage chamber 21 during the injection process. When the injection is completed, the seal 30 is driven to switch to the sealing position by the movable part 40, and the exhaust structure is blocked, so as to realize the rapid sealing of the liquid storage opening 210 and avoid oil leakage. In this way, on the premise of ensuring smooth injection, on the one hand, the injection part 31 does not need to be set in the form of a through hole, but is set at the liquid storage opening 210 by the seal 30, which can cover the liquid storage opening 210 and avoid the problem that the liquid storage chamber 21 is contaminated before the injection. On the other hand, since the oil cup 20 and the suction nozzle 10 have been assembled during manufacturing, when the user fills the electronic atomization device 100, that is, when filling the liquid at the user end, there is no need to assemble the oil cup 20 and the suction nozzle 10, which avoids the problem of reduced sealing performance caused by the oil cup 20 and the suction nozzle 10 being squeezed or pressed into place or misaligned during the assembly process. In addition, the smooth filling is ensured by moving the position of the seal 30, that is, the risk of sealing failure can be reduced by reducing the movable parts, ensuring that the electronic atomization device 100 has good sealing performance and improving the sealing reliability of the electronic atomization device 100. In addition, since the suction nozzle 10 and the oil cup 20 have been fixedly connected to form an integrated state when leaving the factory, when the user fills the oil cup 20, he only needs to perform the filling operation at the injection part 31, and there is no need to assemble the suction nozzle 10 and the oil cup 20, which further improves the convenience of the user to use the electronic atomization device 100.

[0032] It is understandable that the electronic atomization device 100 is further provided with an atomization assembly 50 and a base 60. The atomization assembly 50 is used to heat and atomize the atomization medium in the liquid storage chamber 21 to form an aerosol, and the aerosol is inhaled by the user through the suction nozzle 10. The base 60 is sealed to the bottom of the oil cup 20 to form a closed space in the oil cup 20. Other structures and operations of the electronic atomization device 100 have been recorded in the relevant technology for ordinary technicians in this field and will not be described in detail here.

[0033] Exemplarily, the exhaust structure may be formed on the seal 30 or on the oil cup 20 , or a portion of the seal 30 and a portion of the oil cup 20 may together constitute the exhaust structure, which will be described below with examples.

[0034] In some examples, the exhaust structure includes an exhaust channel provided on the seal 30 or the oil cup 20, the exhaust channel is connected to the outside through the air suction chamber 14 or directly connected to the outside, when the seal 30 is in the oil filling position, the exhaust channel is opened so that the liquid storage chamber 21 is connected to the outside through the exhaust channel, and when the seal 30 is in the sealing position, the exhaust channel is closed. For example, an exhaust hole can be provided on the inner wall of the oil cup 20, and when the seal 30 moves to the sealing position, the exhaust hole can be blocked. Alternatively, the seal 30 is provided with an exhaust hole connected to the air suction chamber 14 at the matching position with the oil cup 20, and the exhaust hole can be blocked by moving the oil cup 20.

[0035] In other examples, the sealing effect of the sealing position can also be formed by the sealing cooperation between the sealing member 30 and other components. This sealing method will be described in detail below.

[0036] For example, in the process of switching from the oil filling position to the sealing position, the seal 30 can be switched by moving the whole or part of it. The seal 30 can be switched by partial movement, which can further improve the sealing reliability of the seal 30. The following is an example of the seal 30 switching by partial movement.

[0037] In some embodiments, the seal 30 includes a movable portion 32 and a fixed portion 33, the exhaust structure is at least partially disposed on the movable portion 32, the fixed portion 33 is connected to the oil cup 20, and the fixed portion 33 covers a portion of the liquid storage opening 210, and the movable portion 32 is movable relative to the fixed portion 33, so that the seal 30 switches from the oil filling position to the sealing position. The injection portion 31 is disposed on at least one of the movable portion 32 or the fixed portion 33, or the injection portion 31 is disposed between the movable portion 32 and the fixed portion 33, one end of the movable member 40 abuts against the movable portion 32, and the other end is exposed at the open end of the suction chamber 14. That is, by fixing the fixed portion 33 relative to the oil cup 20, the sealing performance between the seal 30 and the oil cup 20 can be improved, and a gap caused by relative movement between the fixed portion 33 and the oil cup 20 can be avoided, thereby avoiding problems such as oil leakage. At the same time, the movable portion 32 can move relative to the fixed portion 33, so that the movable portion 32 can open or seal the liquid storage opening 210, and the sealing member 30 can be switched from the oil filling position to the sealing position. Compared with the overall movement of the sealing member 30, only the movable portion 32 is moved, which can reduce the resistance of the movable portion 32, thereby improving the convenience of operation when the sealing member 30 switches between the two positions.

[0038] In some embodiments, the direction from the opening end 140 to the liquid storage opening 210, that is, the thickness direction of the sealing member 30 (eg, Figures 1 to 3The movable portion 32 is used to move relative to the fixed portion 33 under the pushing action of the movable member 40, so that the seal 30 is switched from the oil filling position to the sealing position. By moving the seal 30 by the pushing action, the operation steps when the seal 30 is switched to the sealing position can be simplified and the operation difficulty can be reduced. That is, the user only needs to push the movable portion 32 to move after the injection is completed to switch the seal 30 to the sealing position. At the same time, it can also prevent the movement of the parts of the seal 30 other than the movable portion 32, thereby improving the sealing reliability of the seal 30.

[0039] Exemplarily, the seal 30 is configured as an elastic member, the movable portion 32 and the fixed portion 33 are integrally configured, and the seal 30 changes the relative position of the movable portion 32 and the fixed portion 33 by deformation. By utilizing the elastic deformation characteristics of the elastic member, on the one hand, the movable portion 32 and the fixed portion 33 can be relatively movable, and on the other hand, the movable portion 32 and the fixed portion 33 can be integrally configured to reduce the risk of poor sealing during the relative movement of the two, and further improve the sealing reliability of the seal 30. Exemplarily, the seal 30 can be made of a material with good elasticity such as rubber, silicone, and organic materials.

[0040] In some embodiments, the exhaust structure further includes an assembly through hole 320 disposed on the movable portion 32, and a vent pipe 211 disposed in the liquid storage chamber 21, one end of the vent pipe 211 being fixed to the oil cup 20, and the other end being a free end 2110 facing the assembly through hole 320. When the seal 30 is located at the oil filling position, the movable portion 32 is separated from the vent pipe 211, and the assembly through hole 320 is connected to the air inhalation chamber 14 and the liquid storage chamber 21; when the seal 30 is located at the sealing position, the free end 2110 is located in the assembly through hole 320 and is in sealing contact with the movable portion 32, so that the air inhalation chamber 14 is isolated from the liquid storage chamber 21. The vent pipe 211 can transfer the atomized aerosol to the mouthpiece 10 for the user to inhale. When the vent pipe 211 is arranged in the liquid storage chamber 21, the vent pipe 211 is used in conjunction with the seal 30 to seal the liquid storage opening 210, which can make the structure of the entire oil cup 20 more compact. For example, the side wall of the vent pipe 211 can form two connection states, either open or closed, with the movable part 32, thereby realizing the switching of the seal 30 between the oil filling position and the sealing position.

[0041] Optionally, the free end 2110 of the vent pipe 211 is located in the assembly through hole 320, and an exhaust gap connecting the liquid storage chamber 21 and the suction chamber 14 is formed between the outer wall of the free end 2110 and the inner wall of the assembly through hole 320. A sealing step 3201 is also provided in the assembly through hole 320. The vent pipe 211 is connected to the suction nozzle 10 through the assembly through hole 320. The sealing step 3201 is used to abut against the outer wall of the vent pipe 211 when the sealing member 30 is in the sealing position. The sealing step 3201 and the outer wall of the vent pipe 211 are in contact with each other, so that the liquid storage opening 210 can be blocked, thereby achieving the sealing of the liquid storage chamber 21. When the sealing member 30 is in the oil filling position, the liquid storage chamber 21 and the vent pipe 211 are connected to the assembly through hole 320 together. In this way, the assembled structure of the oil cup 20, the vent pipe 211 and the sealing member 30 can be made more compact, thereby saving space in the oil cup 20. When liquid is injected into the liquid storage chamber 21, the air in the liquid storage chamber 21 is discharged along the gap between the outer wall of the vent pipe 211 and the inner wall of the assembly through hole 320, which can not only meet the exhaust requirements of the liquid injection process, but also prevent the liquid storage opening 210 from being too large, thereby preventing overflow during the liquid injection process and improving the sealing effect. By extending a portion of the vent pipe 211 into the assembly through hole 320, the contact area between the tube wall of the vent pipe 211 and the inner wall of the assembly through hole 320 can also be increased, thereby improving the sealing performance.

[0042] In some embodiments, the injection part 31 is arranged on the fixing part 33, and the injection part 31 is arranged corresponding to the liquid storage chamber 21. The injection part 31 is used for the injection device to penetrate during the injection, and the injection part 31 is also used to close when the injection device is withdrawn to seal the liquid storage chamber 21. By using the injection device to penetrate the injection part 31, the injection device can be connected to the liquid storage chamber 21, so that the atomized medium is injected into the liquid storage chamber 21, and the injection operation of the electronic atomization device 100 is realized. After the injection device is withdrawn, the injection part 31 can close by itself, thereby avoiding setting the injection part 31 as a normally open opening form. On the one hand, it can meet the sealing requirements of the oil cup 20 during use and avoid oil leakage. On the other hand, it can avoid the liquid storage chamber 21 from being polluted by the outside and affecting the taste of the user when using it. Exemplarily, the injection part 31 can be made of elastic material, such as silicone gel self-healing polysiloxane elastomer, etc., so that the injection part 31 can be automatically closed after being punctured to meet the sealing requirements.

[0043] Furthermore, in order to make it easier to pierce the injection portion 31, in some embodiments, the seal 30 also includes a weak portion integrally formed between the movable portion 32 and the fixed portion 33. The weak portion is arranged around the outer periphery of the movable portion 32, and along the movable direction z of the seal 30, the wall thickness of the weak portion is smaller than the wall thickness of the fixed portion 33 and the movable portion 32, and the injection portion 31 is at least partially located in the weak portion. In this way, the injection device can pierce the injection portion 31. The weak portion refers to a portion other than the weak portion, and the weak portion can be set to a smaller thickness, or the weak portion is made of a material with lower strength, and the portion other than the weak portion is made of a material with higher strength. In this way, the weak portion can be easily pierced by the injection device to achieve the injection operation. The thickness of the weak portion refers to the thickness along the movable direction of the movable portion 32 (such as Figures 1 to 3 By arranging the weak portion around the outer periphery of the movable portion 32, the movable portion 32 can have better mobility relative to the fixed portion 33, which facilitates the movable portion 32 to move relative to the fixed portion 33, reduces the resistance during the movement of the movable portion 32, and improves the convenience of operation when switching the position of the movable portion 32. For example, the weak portion can be an area surrounding the outer periphery of the movable portion 32, or it can be as shown in FIG. Figure 4 As shown, two areas are symmetrically arranged on both sides of the movable portion 32 .

[0044] In some embodiments, the opening end 140 is further provided with a liquid injection port 11, which is arranged corresponding to the injection portion 31, and the liquid injection port 11 is used for the liquid injector to extend into the injection portion 31. By using the corresponding positions of the liquid injection port 11 and the injection portion 31, the liquid injector can be inserted into the injection portion 31 in a straight line when extending into the inside of the suction nozzle 10 through the liquid injection port 11 and reaching the injection portion 31, thereby avoiding the liquid injector from tilting or turning, etc., and improving the convenience and reliability of the liquid injection operation.

[0045] In some embodiments, the nozzle 10 is also provided with an air inlet 12, and the liquid injection port 11 is arranged in the air inlet 12. The electronic atomization device 100 also includes a movable part 40, one end of the movable part 40 abuts against the sealing part 30, and the other end is located at the air inlet 12. The movable part 40 is used to push the sealing part 30 under the pushing action, so that the sealing part 30 moves from the oil filling position to the sealing position. By setting the movable part 40, the movable part 32 of the sealing part 30 can be pushed from the liquid filling position to the sealing position at the position of the air inlet 12 with the help of the movable part 40, so that the operation of switching the position of the sealing part 30 is more convenient. Exemplarily, the user can use the liquid injector to push the movable part 40 after the liquid injection is completed to push the sealing part 30 to the sealing position. For example, a pushing part 201 can also be provided on the liquid injector, and the pushing part 201 can enter the air inlet cavity 14 using the air inlet 12 and abut against the other end of the movable part 40, thereby pushing the movable part 40. Of course, in other examples, the movable member 40 may also extend out of the air inlet 12, that is, the other end of the movable member 40 is exposed to the suction nozzle 10, and the user may use a tool or hand to press the movable member 40, so as to use the movable member 40 to push the sealing member 30 to the sealing position. After the sealing member 30 reaches the sealing position, the other end of the movable member 40 may be flush with the edge of the air inlet 12, or lower than the edge of the air inlet 12, so that the movable member 40 does not affect the user's use of the suction nozzle 10.

[0046] Optionally, in order to enable the movable member 40 to connect the assembly through hole 320 with the air inlet 12, an air guide through hole 41 may be provided on the movable member 40, the open end 140 includes the air inlet 12 connected to the air inlet cavity 14, the air guide through hole 41 extends along the movable direction z of the movable member 40, one end of the air guide through hole 41 is connected to the assembly through hole 320 of the sealing member 30, and the other end is connected to the air inlet 12 of the suction nozzle 10, and a guide cylinder 141 is further provided in the air inlet cavity 14, at least a part of the movable member 40 is provided in the guide cylinder 141, and the movable member 40 is movable relative to the guide cylinder 141. By connecting the air guide through hole 41 to the air inlet 12 and the assembly through hole 320, ventilation can be achieved. By setting the guide cylinder 141, the movable part 40 can be fixed and can also play a guiding role during the movement of the interactive key 40, ensuring that the movable part 40 can move along its axial direction, avoiding deviation in the process of pushing the movable part 40 downward, and ensuring the accuracy and reliability of the user in the operation of pushing the seal 30 to switch from the oil filling position to the sealing position.

[0047] Exemplarily, two injection parts 31 are provided, and the two injection parts 31 are symmetrically arranged on both sides of the movable part 32. Correspondingly, two injection ports 11 are also provided. The injector is provided with two injection tubes, which are arranged at intervals. The pusher 201 is arranged between the two injection tubes, and the two injection tubes form an "H"-shaped structure with the pusher 201. In this way, the injector can not only complete the injection operation, but also use the pusher 201 to push the seal 30 to the sealing position after the injection is completed, thereby improving the convenience of the injection operation and the sealing operation, and improving the practicality of the user when using the electronic atomization device 100.

[0048] In some embodiments, the nozzle 10 is further provided with a stopper 13, which abuts against the fixing portion 33 so that the fixing portion 33 is fixed to the liquid storage opening 210. By using the stopper 13, the fixing portion 33 of the sealing member 30 can be pressed tightly against the top or inner wall of the liquid storage opening 210 to prevent the sealing member 30 from being displaced along the height direction of the liquid storage cavity 21, thereby improving the sealing performance of the sealing member 30, preventing the sealing member 30 from being deformed or displaced, and improving the sealing reliability of the entire electronic atomization device 100.

[0049] In a second aspect, the present application also provides a method for injecting liquid into an electronic atomization device, comprising the following steps:

[0050] S1. Provide electronic atomization device and liquid injector;

[0051] S2. The injector is inserted into the seal of the electronic atomization device, the seal is located at the oil filling position, and the atomization medium is injected into the liquid storage chamber of the electronic atomization device by using the injector;

[0052] S3. Pushing the injector so that the movable member of the seal is pressurized and moves from the oil filling position to the sealing position;

[0053] S4. Pull the injector away from the seal.

[0054] After the injection is completed, the seal is pushed by the injector to switch the seal to the oil filling position, thereby realizing the sealing effect of the seal on the liquid storage chamber, thereby reducing the difficulty of injecting liquid into the electronic atomization device and improving the convenience and reliability of injecting liquid into the electronic atomization device.

[0055] The following is the oil filling process of the electronic atomization device 100: When the user gets the electronic atomization device 100, the oil cup 20 and the suction nozzle 10 are fixedly connected as a whole, and the user does not need to assemble the suction nozzle 10 and the oil cup 20, and the seal 30 of the electronic atomization device 100 (i.e., in the initial state) is at the oil filling position. At this time, the user can use an injector and use the oil filling tube 200 of the injector to insert into the injection part 31 and puncture the injection part 31. Since the injection part 31 is set as a weak part, the weak part has a smaller wall thickness, which makes it easier for the user to puncture the injection part 31. During the oil filling process, the exhaust structure (i.e., the exhaust gap) formed by the inner wall of the seal 30 and the outer wall of the vent pipe 211 is used, and the liquid storage chamber 21 can be connected to the suction chamber 14 and connected to the outside atmosphere through the exhaust gap, so that the gas in the liquid storage chamber 21 is discharged during the liquid filling process, providing high fluidity and reliability of the liquid filling process. After the injection is completed, the user pushes the injector toward the liquid storage chamber 21, and uses the push part 201 between the two oil injection tubes 200 of the injector to push the movable part 40 to drive the seal 30 to move to the sealing position, thereby blocking the exhaust gap, isolating the liquid storage chamber 21 from the air intake chamber 14, and sealing the liquid storage chamber 21, thereby ensuring that the atomized medium does not leak from the liquid storage chamber 21. The user pulls out the oil injection tube 200 of the injector from the injection part 31. The injection part 31 has a self-healing property and can close the part punctured by the oil injection tube 200, thereby sealing the liquid storage chamber 21. After completing the injection operation, the user can use the electronic atomization device 100 normally.

[0056] It should be noted that after the injection is completed, the oil injection tube 200 of the injector can be firstly drawn out from the injection part 31, and then the user can directly press the movable part 40 by hand to push the sealing part 30 to move to the sealing position.
