[0041] Before explaining the liquid injection device provided in the embodiment of the present application, the application scenario of the liquid injection device provided in the embodiment of the present application is specifically described:

[0042] The atomizer in the electronic atomization device heats the aerosol matrix in the liquid storage tank to form an aerosol for the user to use. The liquid storage tank has two forms: one liquid storage tank is an independent component. When the aerosol matrix in the liquid storage tank is used up, the user replaces it with a new liquid storage tank; the other liquid storage tank is a chamber arranged in the atomizer shell, that is, the liquid storage tank formed on the atomizer shell, and the liquid storage tank is provided with a liquid filling port. When the aerosol matrix therein is used up, the liquid storage tank is filled with liquid through the liquid filling port using an additional liquid filling bottle.

[0043] In the related art, the filling bottle is only used to fill the liquid storage tank, so its function is relatively simple. When the user uses the electronic atomization device, an additional filling bottle is required to fill the liquid, which makes the user experience poor.

[0044] To this end, an embodiment of the present application provides a liquid injection device. The liquid injection device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in combination with the accompanying drawings.

[0045] The following describes the liquid injection device provided in the embodiment of the present application in detail through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0046] Please refer to Figure 2 and Figure 3 According to an embodiment of the present application, the liquid injection device includes: a main body 1, a switch mechanism 2 and a liquid injection piece 3, the main body 1 has a liquid storage chamber 11 and a first opening 12 connected to the liquid storage chamber 11, the liquid storage chamber 11 is used to store the aerosol matrix; the switch mechanism 2 is provided at the first opening 12, and is used to conduct or block the first opening 12; the liquid injection piece 3 is detachably connected to the switch mechanism 2, and the liquid injection piece 3 is provided with a liquid injection hole 31, and the liquid injection hole 31 is connected to the first opening 12; when the liquid injection piece 3 is assembled with the switch mechanism 2, the first opening 12 is connected to the liquid injection hole 31; when the liquid injection piece 3 is not assembled with the switch mechanism 2, the switch mechanism 2 blocks the first opening 12, and under the action of external force, the switch mechanism 2 can conduct the first opening 12.

[0047] In an embodiment of the present application, the liquid injection device includes a main body 1, a switch mechanism 2 and a liquid injection piece 3. The main body 1 is provided with a liquid storage chamber 11 for storing an aerosol matrix and a first opening 12 connected thereto. The switch mechanism 2 is provided at the first opening 12 to open or block the first opening 12. The liquid injection piece 3 is detachably connected to the switch mechanism 2. The liquid injection piece 3 is provided with a liquid injection hole 31, and the liquid injection hole 31 is connected to the first opening 12. When the liquid injection piece 3 is assembled with the switch mechanism 2, the liquid injection device is used for liquid injection, and the first opening 12 is connected to the liquid injection hole 31. When the liquid injection piece 3 is not assembled with the switch mechanism 2, the switch mechanism 2 blocks the first opening 12, and under the action of an external force, the switch mechanism 2 can open the first opening 12, so that the main body can be installed in the electronic atomization device to replenish the electronic atomization device. In this way, the liquid injection device has multiple uses and improves the user experience. In this way, the liquid injection device has multiple uses and is simple to switch between different working states, which reduces the number of components that the user needs to use and improves the user experience.

[0048] In one embodiment, the main body 1 has a liquid storage chamber 11 and a first opening 12. The liquid storage chamber 11 is connected to the first opening 12. The liquid storage chamber 11 is used to store the aerosol matrix. The aerosol matrix can be injected into the liquid storage chamber 11 through the first opening 12, or the aerosol matrix in the liquid storage chamber 11 flows out through the first opening 12.

[0049] It should be explained that when the injection device is in a state, please refer to Figure 2When the liquid injection part 3 is assembled with the switch mechanism 2, the liquid injection device is used as an independent liquid injection unit. The liquid injection part 3 applies a downward force to the switch mechanism 2 to push the switch mechanism 2 open. The liquid injection hole 31 is connected to the liquid storage chamber 11 through the switch mechanism 2, so that the aerosol matrix in the liquid storage chamber 11 can flow out along the liquid injection hole 31. The liquid injection hole 31 is inserted into the liquid injection port on the liquid storage tank of the atomizer to fill the liquid storage tank. It should be noted that in this application, when the liquid injection part 3 is assembled with the switch mechanism 2, the direction of the liquid injection part 3 relative to the switch mechanism 2 is up, above, upper side, top or top, and the opposite direction is down, below, lower side, bottom or bottom.

[0050] When the injection device is in another state, please refer to Figure 3 When the liquid injection member 3 is not assembled with the switch mechanism 2, that is, the liquid injection member 3 and the switch mechanism 2 are in a disengaged state, the switch mechanism 2 blocks the first opening 12 without being affected by external forces, so that the liquid injection device is sealed. When the switch mechanism 2 is subjected to a downward external force, it moves downward to a certain extent, and the first opening 12 can be opened. In one embodiment, please refer to Figure 13 When the liquid injection device is installed to the liquid injection installation port 6 of the electronic atomization device, the liquid injection installation port 6 pushes the switch mechanism 2 to open the switch mechanism 2, so that the aerosol matrix in the liquid storage chamber 11 can flow out from the first opening 12 for use by the electronic atomization device.

[0051] It can be understood that the injection part 3 is detachably connected to the switch mechanism 2, that is, the injection part 3 and the switch mechanism 2 are connected by at least one of the following connection methods: snap connection, screw connection, interference fit connection, etc. Those skilled in the art can set it according to needs, and this application does not limit this.

[0052] It can be understood that the main body 1 is a bottle body that is easy for users to hold, has a lower cost, and is easy to manufacture. The volume of the bottle body is 5ml-15ml, and the outer surface of the bottle body is provided with multiple concave points for easy gripping. Of course, this application is not limited to the use of 5ml-15ml bottles to contain aerosol substrates. Bottles of other volumes can also be used, such as 20ml, 30ml, 40ml, 50ml, 100ml or larger. Those skilled in the art will make their choices based on market demand or different application scenarios, and this application does not impose any restrictions on this.

[0053] In one embodiment of this application, please refer to Figure 2 、 Figure 3 and Figure 9The switch mechanism 2 includes: a fixing member 21, a switch member 22 and an elastic member 23. The fixing member 21 has a through mounting hole 211; the switch member 22 is movably connected to the mounting hole 211, and the elastic member 23 is arranged between the fixing member 21 and the switch member 22. One end of the elastic member 23 is connected to the fixing member 21, and the other end is connected to the switch member 22; the switch member 22 can move along the axial direction of the first opening 12 so that the switch member 22 can switch between the first position F and the second position S; when the switch member 22 is in the first position F, the first opening 12 is in a conducting state; when the switch member 22 is in the second position S, the first opening 12 is in a blocked state.

[0054] In the examples of this application, please refer to Figure 9 The fixing member 21 is connected to the inner wall of the first opening 12, and the fixing member 21 has a through mounting hole 211; the switch member 22 is movably connected to the mounting hole 211, and the elastic member 23 is provided between the fixing member 21 and the switch member 22, one end of the elastic member 23 is connected to the fixing member 21, and the other end is connected to the switch member 22; the switch member 22 can move along the axial direction of the first opening 12 so that the switch member 22 can switch between the first position F and the second position S; when the switch member 2 is in the first position F, the first opening 12 is in a conducting state; when the switch member 22 is in the second position S, the first opening 12 is in a blocked state.

[0055] When the elastic member 23 is in the natural state, the switch member 22 is in the second position S, and the first opening 12 is in the blocked state, which can effectively prevent the liquid injection device from leaking. When a downward external force is applied to the switch member 22, the elastic member 23 is compressed, and the switch member 22 moves from the second position S to the first position F. At this time, please refer to Figure 2 and Figure 13 , at least part of the structure of the switch member 22 is exposed outside the fixing member 21 and extends into the liquid storage chamber 11, and the first opening 12 is conductive; after the external force on the switch member 22 is removed, the elastic member 23 rebounds and drives the switch member 22 to move upward, and the switch member 22 moves from the first position F to the second position S, please refer to Figure 3 and Figure 9 , the first opening 12 is blocked.

[0056] It should be noted that the fixing member 21 is connected to the inner wall of the first opening 12 by a snap connection, an interference fit connection, etc., to facilitate the assembly of the switch member 22. Of course, the fixing member 21 can also be integrally formed with the body 1 to facilitate processing. Those skilled in the art can configure it according to their needs, and this application does not impose any restrictions on this.

[0057] It can be understood that the switch member 22 is movably connected in the mounting hole 211. Specifically, the switch member 22 is slidably connected to the hole wall of the mounting hole 211 along the axial direction of the mounting hole 211, thereby making it easier to achieve communication or isolation between the flow cavity 221 and the liquid storage cavity 11.

[0058] In a specific application, when the switch member 22 is in the first position, the switch member 22 is acted upon by an external force, for example, the liquid injection member 3 pushes the switch member 22 downward, or the liquid injection installation port 6 of the electronic atomization device pushes the switch member 22, thereby placing the switch member 22 in the first position. Figure 9 When the switch member 22 is in the second position, the elastic member 23 rebounds, driving the switch member 22 to move upward. At this time, the first opening is in a blocked state.

[0059] In one embodiment of this application, please refer to Figure 2 、 Figure 10 and Figure 11 The switch element 22 is provided with a flow cavity 221 and a second opening 225 communicating with the flow cavity 221 . When the switch element 22 is in the first position, the liquid storage cavity 11 communicates with the flow cavity 221 through the second opening 225 to achieve conduction of the first opening 12 .

[0060] It should be explained that when the switch member 22 is in the first position, the circulation cavity 221 is provided with a second opening 225 in the circumferential direction of the switch member 22. When the switch member 22 is at least partially exposed from the fixing member 21 and extends into the liquid storage cavity 11, the second opening 225 is located in the liquid storage cavity 11, and the circulation cavity 221 communicates with the liquid storage cavity 11, thereby achieving conduction of the first opening 12. When the switch member 22 is in the second position, the second opening 225 is located in the mounting hole 211 and is blocked, thereby disconnecting the circulation cavity 221 from the liquid storage cavity 11 and achieving blockage of the first opening 12. In one embodiment, when the second opening 225 is located in the mounting hole 211, it can be isolated from the liquid storage cavity 11 by a sealing member that is an interference fit with the mounting hole 211, thereby achieving blockage of the first opening 12. The sealing member can be provided on the fixing member 21 or the switch member 22.

[0061] In one embodiment of this application, please refer to Figure 10 and Figure 11 The switch mechanism 2 further includes a sealing member 24 . A first groove 222 is provided on the outer surface of the switch member 22 . The first groove 222 is provided on a side of the second opening 225 close to the liquid storage chamber 11 . The sealing member 24 is provided in the first groove 222 .

[0062] In the embodiment of the present application, a first groove 222 is provided on the outer surface of the switch member 22, and the first groove 222 is provided on the side of the second opening 225 close to the liquid storage chamber 11. The switch mechanism 2 also includes a sealing member 24, and the sealing member 24 is provided in the first groove 222, so that when the switch member 22 is in the second position, the sealing member 24 can seal between the mounting hole 211 and the switch member 22, thereby preventing the aerosol matrix in the liquid storage chamber 11 from flowing out from between the switch member 22 and the mounting hole 211, causing leakage.

[0063] It is understandable that the seal 24 can be at least one of a V-shaped seal ring, a U-shaped ring, an O-shaped seal ring, a rectangular seal ring, a Y-shaped seal ring, etc., which are low-cost and easy to select. Those skilled in the art can choose according to their needs, and this application does not limit this.

[0064] In one embodiment of this application, please refer to Figure 10 and Figure 11 A stopper 224 is provided at one end of the switch member 22 away from the first opening 12 , thereby preventing the switch member 22 from being separated from the mounting hole 211 and causing leakage.

[0065] In one embodiment of this application, please refer to Figure 10 and Figure 11 The flow cavity 221 has a cavity bottom 2111 and a cavity opening 2212 opposite to each other. The cavity bottom 2111 is provided with a guide portion 223 , and the guide portion 223 extends from the cavity bottom 2111 to the cavity opening 2112 .

[0066] In the embodiment of the present application, a guide portion 223 extending toward the cavity opening 2212 is provided at the cavity bottom 2111 of the circulation cavity 221. This can prevent the aerosol matrix from forming a thin film at the cavity opening 2212 due to surface tension when flowing out of the circulation cavity 221, thereby preventing the aerosol matrix from flowing out smoothly.

[0067] In one embodiment of this application, please refer to Figure 12 , several gaps are formed between the liquid injection part 3 and the switch mechanism 2.

[0068] In the embodiment of the present application, a plurality of gaps are formed between the liquid injection piece 3 and the switch mechanism 2, thereby facilitating the user to remove the liquid injection piece 3 and improving the convenience of switching between the use states of the liquid injection device.

[0069] Understandably, please refer to Figure 2When the injection piece 3 is mounted on the switch mechanism 2, the injection piece 3 abuts against the fixing piece 21 and is at least partially inserted into the mounting hole 211. The multiple gaps formed between the injection piece 3 and the switch mechanism 2 can be formed by a plurality of second grooves 32 surrounding the side of the injection piece 3 facing the body 1, with the plurality of gaps formed between the plurality of second grooves 32 and the fixing piece 21; or a plurality of third grooves (not shown) surrounding the side of the fixing piece 21 facing the injection piece 3, with the plurality of gaps formed between the plurality of third grooves and the injection piece 3; or a plurality of second grooves 32 surrounding the side of the injection piece 3 facing the body 1, with the plurality of third grooves correspondingly provided on the side of the fixing piece 21 facing the injection piece 3, with the second grooves 32 and the third grooves correspondingly enclosing to form the multiple gaps.

[0070] In one embodiment of this application, please refer to Figure 2 The liquid injection part 3 and the switch mechanism 2 are connected together by screw threads or snap fasteners.

[0071] In the embodiment of the present application, by connecting the liquid injection part 3 and the switch mechanism 2 together by means of threads or snaps, on the one hand, the user can quickly disassemble and assemble, thereby improving the user experience; on the other hand, the stability of the connection is ensured.

[0072] Please refer to Figure 4 、 Figure 5 and Figure 6 In one embodiment of the present application, the liquid injection device further includes a first cover body 4 , which is sealed at the first opening 12 .

[0073] In the examples of this application, please refer to Figure 4 By providing the first cover body 4 to seal the first opening 12, on the one hand, the risk of aerosol matrix flowing out of the liquid storage chamber 11 is reduced; on the other hand, the possibility of external debris entering the liquid storage chamber 11 and contaminating the aerosol matrix is ​​reduced.

[0074] In one embodiment of this application, please refer to Figure 3 The main body 1 is provided with a first thread 13, which is provided on the outer wall of the first opening 12. Figure 6 , a second thread 44 is provided on the inner wall of the first cover 4, please refer to Figure 4 The first thread 13 and the second thread 44 are adapted to be screwed together, so that the first cover body 4 can cover the first opening 12 .

[0075] In a specific application, the first thread 13 is an external thread, and the second thread 44 is an internal thread. The first thread 13 and the second thread 44 are engaged with each other and tightened.

[0076] In one embodiment of this application, please refer to Figure 4 and Figure 6A accommodating space 41 is provided in the first cover body 4 , and the liquid injection member 3 is at least partially accommodated in the accommodating space 41 . A protrusion 42 is provided on the side wall of the accommodating space 41 facing the first opening 12 , and the protrusion 42 is used to block the liquid injection hole 31 .

[0077] In the embodiment of the present application, a receiving space 41 is defined within the first cover 4, and the liquid injection member 3 is at least partially accommodated within the receiving space 41. A protrusion 42 is defined on the sidewall of the receiving space 41 facing the first opening 12, and the protrusion 42 is used to block the liquid injection hole 31. Thus, when the liquid injection device is in the first operating state, the first cover 4 can prevent the aerosol matrix in the liquid storage chamber 11 from flowing out of the liquid injection hole 31, making it easier for the user to move the liquid injection device during use.

[0078] It should be explained that the outer diameter of the protrusion 42 should be smaller than or equal to the inner diameter of the injection hole 31 , so that as much of the protrusion 42 as possible can be inserted into the injection hole 31 to block the injection hole 31 .

[0079] In one embodiment of this application, please refer to Figure 1 and Figure 4 The liquid injection device also includes a second cover 5, which is sleeved on the outside of the first cover 4. Please refer to Figure 5 The first cover 4 is provided with a first clamping portion 43 on the side facing away from the main body 1. Figure 7 A second clamping portion 51 adapted to the first clamping portion 43 is provided in the second cover body 5; the second cover body 5 can move along the axial direction X of the first opening 12 to switch between the first state and the second state. When the second cover body 5 is in the first state, the second clamping portion 51 is clamped with the first clamping portion 43, and the first cover body 4 rotates with the second cover body 5; when the second cover body 5 is in the second state, the second clamping portion 51 is separated from the first clamping portion 43, and the second cover body 5 can rotate relative to the first cover body 4.

[0080] In the embodiment of the present application, the second cover 5 can move along the axis direction X of the first opening 12, thereby switching between the first state and the second state. When the second cover 5 is in the first state, the second engaging portion 51 of the second cover 5 engages with the first engaging portion 43 on the first cover 4, so that the first cover 4 can rotate along with the second cover 5, thereby enabling the first cover 4 to be separated from or combined with the body 1. When the second cover 5 is in the second state, the second engaging portion 51 separates from the first engaging portion 43, at which point the second cover 5 can rotate relative to the first cover 4. In this way, it is possible to effectively prevent children from accidentally swallowing food after opening the lid, thereby ensuring personal safety.

[0081] It should be explained that the two positions of the second cover body 5 are achieved by whether the user applies pressure. When the user applies external force to the second cover body 5, the second cover body 5 is in the first state, and the second clamping portion 51 in the second cover body 5 is clamped with the first clamping portion 43 on the first cover body 4. At this time, the second cover body 5 is connected to the first cover body 4 in the circumferential direction. When the second cover body 5 is rotated, it can drive the first cover body 4 to rotate, thereby separating it from the main body 1 and canceling the cover on the first opening 12. The user can inject liquid through the liquid injection piece 3, or inject aerosol matrix into the liquid storage chamber through the first opening 12.

[0082] When the second cover 5 is not subjected to external force, the second cover 5 is in the second state, and the second clamping portion 51 is separated from the first clamping portion 43. At this time, the second cover 5 is idling when rotating and cannot drive the first cover 4 to rotate, thereby effectively preventing children from opening it.

[0083] For specific applications, please refer to Figure 5 The first clamping portion 43 is provided on the side of the first cover 4 away from the main body, and a plurality of first clamping portions 43 are provided around the circumference of the first cover 4; Figure 7 The second cover 5 is provided with a plurality of second clamping portions 51 on one side facing the first cover 4. The plurality of second clamping portions 51 are arranged around the circumference of the second cover 5. The positions of the second clamping portions 51 and the first clamping portions 43 correspond to each other. Figure 4 When external force is applied to the second cover body 5, each second clamping portion 51 can be inserted into a corresponding first clamping portion 43, so that the second cover body 5 is connected to the first cover body 4 along the circumferential direction. When the second cover body 5 rotates along the circumferential direction, it can drive the first cover body 4, thereby opening the first opening 12 of the liquid injection device.

[0084] It should be explained that when one of the first clamping portion 43 and the second clamping portion 51 is a clamping slot, the other is a buckle, thereby achieving clamping.

[0085] In one embodiment of this application, please refer to Figure 4 、 Figure 7 and Figure 8 Along the axial direction X of the first opening 12 , an elastic member 52 is provided between the second cover body 5 and the first cover body 4 , one end of the elastic member 52 is connected to the first cover body 4 , and the other end is connected to the second cover body 5 .

[0086] In the examples of this application, please refer to Figure 7By providing an elastic member 52 on the side of the second cover 5 facing the first cover 4, when the second cover 5 is in the first state, the elastic member 52 is compressed; when the second cover 5 is in the second state, the elastic member 52 rebounds, driving the second engaging portion 51 to separate from the first engaging portion 43. This improves the efficiency of separating the first cover 4 and the second cover 5, and prevents the first cover 4 and the second cover 5 from being connected together without external force, thereby preventing the first cover 4 and the second cover 5 from being opened by children.

[0087] It should be explained that the elastic member 52 can be made of rubber, which is convenient to process and has low cost.

[0088] In one embodiment of the present application, the elastic member 52 can be integrally formed with the second cover body 5 , thereby facilitating processing and reducing costs.

[0089] In a specific application, the elastic member 52 is arranged on the side of the second cover body 5 facing the first cover body 4. It needs to be ensured that when a downward external force is applied to the second cover body 5, the elastic member 52 needs to be compressed, so that when the external force is removed, the elastic member 52 can rebound and drive the second cover body 5 to move upward, thereby driving the second clamping portion 51 to separate from the first clamping portion 43.

[0090] In one embodiment of this application, please refer to Figure 4 、 Figure 7 and Figure 8 A accommodating cavity 54 is provided in the second cover body 5, and the accommodating cavity 54 has a third opening 53 connected thereto. The first cover body 4 is accommodated in the accommodating cavity 54, and a limiting portion 55 is provided at the third opening 53. The limiting portion 55 is used to limit the movement of the first cover body 4 along the axial direction X of the liquid injection hole 31.

[0091] In the embodiment of the present application, a stopper 55 is provided at the third opening 53 to limit the movement of the first cover 4 along the axial direction X of the liquid injection hole. Thus, when an upward external force is applied to the second cover 5, the stopper 55 can prevent the first cover 4 from moving downward and separating from the second cover 5, thereby improving the safety of the liquid injection device.

[0092] It is understandable that during use, in addition to holding the main body 1, the user may also hold the second cover 5. A limiting portion 55 is provided at the third opening 53 to prevent the first cover 4 from moving downward and separating from the second cover 5, thereby improving the safety of the liquid injection device.

[0093] In one embodiment of this application, please refer to Figure 13The present application discloses an electronic atomization device, including a liquid injection device as described in any of the above embodiments, the electronic atomization device includes a liquid injection mounting port 6, when the liquid injection device is not equipped with a liquid injection part 3, and the liquid injection device is assembled into the liquid injection mounting port 6, the switch mechanism 2 turns on the first opening 12.

[0094] In an embodiment of the present application, when the liquid injection part 3 in the liquid injection device is removed and installed in the liquid injection installation port 6, the liquid injection device plays a role of replenishing liquid in the electronic atomization device and can serve as a liquid storage unit of the electronic atomization device, thereby enriching the use of the liquid injection device.

[0095] It should be explained that when the liquid injection device is assembled into the liquid injection installation port 6, the liquid injection installation port 6 pushes the switch member 22 toward the liquid storage chamber 11, so that the switch member 22 at least partially extends into the liquid storage chamber 11. The second opening 225 on the switch member 22 connects the liquid storage chamber 11 with the circulation chamber 221, and then connects to the first opening 12, thereby achieving conductivity of the first opening 12. In this way, the aerosol matrix in the liquid storage chamber 11 can flow into the liquid injection installation port 6 through the second opening 225, the circulation chamber 221, and the first opening 12 in sequence, and is used by the electronic atomization device, thereby generating an aerosol for inhalation by the user.
