The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0051] 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] The atomizer, electronic atomizing device, and liquid injection system provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an atomizer according to some embodiments of this application includes: a housing 1, a sealing member 2, and a nozzle 3. The housing 1 is provided with an independent airflow hole 10 and a first liquid storage chamber 11. The airflow hole 10 is used for aerosol outflow. The housing 1 is provided with an injection hole 12 communicating with the first liquid storage chamber 11. The sealing member 2 is provided with a sealing part 21, which is used to seal the injection hole 12 and can release the sealing of the injection hole 12 under the action of external force. The nozzle 3 is detachably connected to the housing 1. The nozzle 3 is provided with a suction hole 30, which communicates with the airflow hole 10. The nozzle 3 is provided with a protrusion 31 extending toward the first liquid storage chamber 11, and the protrusion 31 abuts against the sealing part 21.

[0054] In this embodiment, the sealing part 21 can seal the injection hole 12, reducing the possibility of leakage from the injection hole 12. At the same time, the sealing part 21 can release the seal on the injection hole 12 under the action of external force, thereby injecting the aerosol matrix into the first storage chamber 11. After the aerosol is injected, the suction nozzle 3 is installed on the housing 1. The protrusion 31 of the suction nozzle 3 abuts against the sealing part to seal the injection hole and other objects formed on the sealing part by external force, thereby further reducing the possibility of leakage during use. Compared with related technologies, there is no need to add an extra silicone plug, and the operation is simpler.

[0055] It should be noted that, as Figure 4 and Figure 5 As shown, when injecting liquid into the atomizer, it needs to be inverted (with the nozzle 3 facing downwards). The following explanation uses the injection component 100 as an example: When injecting the aerosol matrix using the injection component 100, the nozzle 3 is removed, and the injection component 100 pierces the sealing portion 21 in the injection hole 12 to inject the aerosol matrix into the first liquid storage chamber 11. Inverting the atomizer allows the aerosol matrix to gradually flow upwards from the bottom of the first liquid storage chamber 11. The aerosol matrix then flows to the outer periphery of the atomizing component 7. The liquid guide can squeeze out the air in the first liquid storage chamber 11 and the liquid guide to reduce the air bubbles in the liquid guide, reduce the impact of air bubbles on the delivery of aerosol matrix to the heating element 71, reduce the possibility of the heating element 71 burning dry, and also reduce the risk of leakage caused by air bubble rupture; after the liquid injection is completed, the suction nozzle 3 is installed on the housing 1, and the protrusion 31 on the suction nozzle 3 abuts against the sealing part 21 to seal the injection hole formed by the liquid injection element 100 on the sealing part 2, etc., and reduce the risk of leakage caused by the punctured sealing part 21 during use.

[0056] It should be explained that the sealing part 21 of the sealing member 2 has a certain elasticity. For example, it can be a rubber membrane, a thin film, or a valve. The rubber membrane or thin film can seal inside the injection hole 12, and the injection member 100 can pierce the sealing part 21. After the injection member 100 is withdrawn, the rubber membrane or thin film (sealing part 21) can shrink. When the sealing part 21 is a valve, multiple valves can seal the injection hole 12 without external force. When multiple valves are subjected to external force, they can open to form an opening communicating with the injection hole 12. The sealing part 21 of the sealing member 2 can also be a silicone block. At least a portion of the silicone block can be inserted into the injection hole 12 to seal the injection hole 12. Of course, it can also be other elastic materials that can seal and be pierced or opened under external force. Those skilled in the art can make settings according to actual needs, and this application does not limit them.

[0057] In a specific application, the housing 1 is provided with independent airflow holes 10 and a first liquid storage chamber 11. The airflow holes 10 are used for the aerosol generated by the atomizing component 7 and for air to flow out for user use; the first liquid storage chamber 11 is used to store the aerosol matrix to provide the aerosol matrix to the atomizing component 7, such as... Figure 3 As shown, the first liquid storage chamber 11 can be arranged around the wall of the airflow hole 10, thereby making full use of the internal space of the housing 1.

[0058] Understandably, the nozzle 3 is detachably connected to the housing 1, and the connection can be a snap-fit ​​connection, a threaded connection, a magnetic connection, an interference fit connection, etc. The suction hole 30 of the nozzle 3 is connected to the airflow hole 10, so that the user can extract the aerosol from the suction hole 30 for consumption.

[0059] The suction nozzle 3 is provided with a protrusion 31 extending toward the first liquid storage chamber 11. The protrusion 31 abuts against the sealing part 21. Specifically, when the sealing part 21 is not subjected to external force, it can seal the injection hole 12. When the sealing part 21 is subjected to external force (the injection part 100), the sealing part 21 may be opened or punctured to form an injection hole, so as to inject the aerosol matrix into the first liquid storage chamber 11. After the external force is removed, the sealing part 21 abuts against the protrusion 31. At this time, the sealing part 21 rebounds or is punctured to form an injection hole, etc. The protrusion 31 can seal the injection hole, etc., further reducing the possibility of aerosol matrix leakage.

[0060] like Figure 3 , Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, in some embodiments of this application, the housing 1 has a first groove 13 at one end facing the nozzle 3, the nozzle 3 is detachably connected to the first groove 13, and the injection hole 12 is located at the bottom of the first groove 13; the sealing member 2 also includes a body part 22, which is embedded in the first groove 13, and at least part of the body part 22 protrudes towards the injection hole 12 to form a sealing part 21. A second groove 211 is formed in the sealing part 21, which is recessed towards the first liquid storage cavity 11. The protrusion 31 is inserted into the second groove 211, and the body part 22 has a first hole 221, which communicates with the airflow hole 10.

[0061] In this embodiment, the end of the housing 1 facing the nozzle 3 is provided with a first groove 13, which allows the nozzle 3 to be at least partially accommodated within the first groove 13, improving the connection reliability between the nozzle 3 and the housing 1. The injection hole 12 is located at the bottom of the first groove 13, which facilitates the sealing part 21 to seal the injection hole 12 and also facilitates the insertion of the injection component 100 into the sealing part 21. Simultaneously, the sealing component 2 also includes a body part 22, which at least partially protrudes towards the injection hole 12 to form the sealing part 21, allowing the sealing part 21 to be inserted into the injection hole 12. This increases the sealing area of ​​the sealing part 21, allowing it to fit tightly against the inner wall of the injection hole 12 and improve its sealing effect. The sealing part 21 has a second groove 211 recessed towards the first liquid storage chamber 11. During injection, the injection component 100 can be inserted into the injection hole 12 through the second groove 211, improving user convenience. Furthermore, after injection, when the suction nozzle 3 is installed into the first groove 13 of the housing 1, the protrusion 31 can be inserted into the second groove 211, ensuring the sealing effect of the protrusion 31.

[0062] In specific applications, the first groove 13 provided in the housing 1 can accommodate at least a portion of the nozzle 3, thereby ensuring the reliability of the connection between the housing 1 and the nozzle 3.

[0063] It should be noted that, as Figure 10 As shown, the sealing component 2 is specifically a silicone component, wherein the body part 22 is embedded in the first groove 13, and the side end face of the body part 22 facing the first liquid storage cavity 11 abuts against the bottom of the first groove 13, which can ensure the connection stability of the sealing component 2, and at least part of it protrudes towards the injection hole 12 to form a sealing part 21, which facilitates sealing the injection hole 12.

[0064] Understandably, such as Figure 3 and Figure 10 As shown, the housing 1 protrudes towards the nozzle 3 to form the opening of the airflow hole 10, and the body part 22 is provided with a first hole 221 that can be fitted onto the outside of the hole wall of the airflow hole 10, thereby forming a stable connection.

[0065] like Figure 11As shown, in some embodiments of this application, at least a portion of the circumferential groove wall of the second groove 211 is provided with a protrusion 2111, which can abut against the protrusion 31.

[0066] In this embodiment of the application, by setting a protrusion 2111 on at least a portion of the circumferential groove wall of the second groove 211, the protrusion 2111 can abut against the protruding post 31, thereby improving the connection reliability of the protruding post 31, reducing the possibility of the protruding post 31 detaching during use, and reducing the risk of falling off due to vibration or collision.

[0067] In specific applications, the protrusion 2111 can be arranged around the circumferential groove wall of the second groove 211 to form a complete "ring" protrusion; it can also be arranged on part of the circumferential groove wall to form a "partial" protrusion; of course, it can also be set as other types of protrusions, such as spiral protrusions, etc. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0068] It should be noted that the sealing component 2 has a certain degree of elasticity, and the protrusion 2111 also has elasticity. When the protrusion 31 is inserted into the second groove 211, the protrusion 2111 can deform when the protrusion 31 is inserted, thereby forming a tight connection.

[0069] like Figure 11 As shown, in some embodiments of this application, the bottom of the second groove 211 is provided with a weak part 2112. The weak part 2112 is used to block the injection hole 12 and can release the blockage of the injection hole 12 under the action of external force. The thickness of the weak part 2112 in the extension direction of the protrusion 31 is D, which satisfies: 0.4mm≤D≤1mm.

[0070] In this embodiment of the application, a weak part 2112 is provided at the bottom of the second groove 211. By setting the thickness D of the weak part 2112 in the extension direction of the protrusion 31 within a reasonable range, the possibility of sealing failure can be reduced while ensuring that the liquid injection component 100 can release the blockage of the liquid injection hole 12 by the weak part 2112.

[0071] It should be explained that when the thickness D of the weak part 2112 in the extension direction of the protrusion 31 is less than 0.4 mm, the weak part 2112 is too thin. After the liquid injection part 100 pierces the weak part 2112, a certain gap is formed. Because the weak part 2112 is too thin, the gap is not easy to shrink, making it easy to leak. On the other hand, when the thickness D of the weak part 2112 in the extension direction of the protrusion 31 is greater than 1 mm, the weak part 2112 is too thick. The force required for the liquid injection part 100 to be inserted is too great, making it difficult to break through with external force and increasing the difficulty of operation.

[0072] In specific applications, the thickness D of the weak part 2112 in the extension direction of the protrusion 31 can be set to any value or a range between two arbitrary values, such as 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm.

[0073] like Figure 11 As shown, in some embodiments of this application, the bottom of the second groove 211 is provided with a deformation part (not shown in the figure). The deformation part can block the injection hole 12. The deformation part can deform and open under the action of external force to connect the second groove 211 with the first liquid storage chamber 11.

[0074] In this embodiment, the deformable part can block the injection hole 12 before deformation, and can deform and open under the action of external force, thereby connecting the second groove 211 and the first liquid storage chamber 11, making the operation more convenient.

[0075] In specific applications, the deformable part can be multiple valves. Before being subjected to external force, the multiple valves can block the injection hole 12. When subjected to external force, they can deform and open to form an opening, so that the injection component 100 can extend into the first liquid storage chamber 11 through the opening and inject the aerosol matrix.

[0076] The deformable part can also be an elastic valve plate, etc. It can be a structure that can block the injection hole 12 when it is not deformed, or can be deformed by external force to open and form an opening. Those skilled in the art can make the setting according to actual needs, and this application does not limit it.

[0077] like Figure 2 , Figure 3 , Figure 5 and Figure 12 As shown, in some embodiments of this application, a first liquid suction member 4 is also included. The first liquid suction member 4 is disposed between the sealing member 2 and the suction nozzle 3. The first liquid suction member 4 is provided with a second hole 41 and a third hole 42, which are spaced apart. The second hole 41 is used for the protrusion 31 to pass through, and the third hole 42 is connected to the airflow hole 10 and the suction hole 30.

[0078] In this embodiment, a first liquid-absorbing component 4 is provided between the sealing component 2 and the suction nozzle 3. The first liquid-absorbing component 4 can absorb the condensate formed during the process of aerosol flowing from the airflow hole 10 to the suction hole 30, thereby reducing the impact of the condensate on the user's taste.

[0079] In a specific application, the second hole 41 of the first liquid-absorbing component 4 allows the protrusion 31 to pass through, ensuring that the protrusion 31 can be smoothly inserted into the second groove 211; while the third hole 42 can connect the airflow hole 10 and the suction hole 30, so that the aerosol formed by the atomizing component 7 can be ingested by the user through the airflow hole 10, the third hole 42 and the suction hole 30 in sequence.

[0080] It should be noted that the first liquid-absorbing element 4 can be made of at least one of the following materials: polyester fiber cotton, polyurethane sponge, non-woven fabric, silicone cotton, ceramic fiber cotton, etc. Those skilled in the art can choose according to the actual situation, and this application does not limit it.

[0081] like Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of this application, the suction nozzle 3 is provided with a first engaging portion 32 facing the outer peripheral surface of the first groove 13, and the groove wall of the first groove 13 is provided with a second engaging portion 131, and the first engaging portion 32 engages with the second engaging portion 131.

[0082] In this embodiment, a first engaging portion 32 is provided on the outer peripheral surface of the nozzle 3 facing the first groove 13, and a second engaging portion 131 is provided on the groove wall of the first groove 13. The first engaging portion 32 engages with the second engaging portion 131, so that the user can quickly install the nozzle 3 into the housing 1 by pressing the nozzle 3. When disassembly is required, the first engaging portion 32 is pressed to disengage it from the second engaging portion 131, and the nozzle 3 can be quickly disassembled. The operation is simple and improves the user's convenience.

[0083] In specific applications, the first snap-fit ​​part 32 can be a buckle, and the second snap-fit ​​part 131 can be a slot, with the buckle snapping into the slot; or the first snap-fit ​​part 32 can be a slot, and the second snap-fit ​​part 131 can be a buckle, with the buckle snapping into the slot; or other snap-fit ​​structures can be used, as long as they facilitate quick assembly and disassembly of the nozzle 3 and the housing 1. This application does not limit these possibilities.

[0084] In some embodiments of this application, a first magnetic suction part (not shown in the figure) may be provided on the outer peripheral surface of the suction nozzle 3 facing the first groove, and a second magnetic suction part (not shown in the figure) may be provided on the groove wall of the first groove 13. The first magnetic suction part and the second magnetic suction part are magnetically connected to each other to realize the quick installation and removal of the suction nozzle 3 and improve the user's convenience.

[0085] In practical applications, the first magnetic part and the second magnetic part are connected by magnetic attraction, which reduces the wear on the nozzle 3 and the housing 1 during disassembly and assembly, and further improves the service life of the atomizer.

[0086] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments of this application, a first sealing member 34 is also included. The suction nozzle 3 is provided with a sealing groove 33 on the outer peripheral surface of the first groove 13. The first sealing member 34 is disposed in the sealing groove 33 to seal the housing 1 and the suction nozzle 3.

[0087] In this embodiment, by providing a first sealing element 34 between the housing 1 and the nozzle 3, a seal can be formed on the connection surface between the housing 1 and the nozzle 3, reducing the outflow of aerosol from the connection surface between the two and improving the airtightness of the atomizer.

[0088] In specific applications, the suction nozzle 3 has a sealing groove 33 on the outer peripheral surface facing the first groove 13, which facilitates the installation of the first sealing element 34. Specifically, the first sealing element 34 is any one of sealing elements such as sealing rings and sealing gaskets, for example, a rubber sealing ring. Those skilled in the art can choose according to actual needs, and this application does not limit it.

[0089] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, a support member 5 and an atomizing component 7 are also included. The support member 5 is embedded in the side of the housing 1 away from the nozzle 3. The support member 5 is provided with a second liquid storage chamber 51, which is connected to the first liquid storage chamber 11. The atomizing component 7 is disposed in the second liquid storage chamber 51. The atomizing component 7 has an atomizing air channel 70, which is connected to the airflow hole 10. The atomizing component 7 is used to heat the aerosol matrix to form an aerosol and output it through the atomizing air channel 70.

[0090] In this embodiment, the second liquid storage chamber 51 in the support member 5 is connected to the first liquid storage chamber 11, and the atomizing component 7 is disposed in the second liquid storage chamber 51. Thus, after the aerosol matrix in the first liquid storage chamber 11 flows into the second liquid storage chamber 51, it can be heated by the atomizing component 7 to form an aerosol, which then flows from the atomizing channel 70 into the airflow hole 10 and is consumed by the user.

[0091] In specific applications, the support member 5 and the housing 1 can be integrally formed or separately formed. When separately formed, the support member 5 can be detachably connected to the housing 1.

[0092] It should be noted that the atomizing component 7 includes a heating element 71 and a liquid guiding element surrounding the heating element 71. The liquid guiding element is filled in the second liquid storage chamber 51 and can guide the aerosol matrix in the first liquid storage chamber 11 to the heating element 71. The heating element 71 can heat the aerosol matrix to form an aerosol. The atomizing air channel 70 is provided in the heating element 71, so that the formed aerosol is drawn out from the atomizing air channel 70 and flows out from the airflow hole 10 for consumption by the user.

[0093] It should be explained that the heating element 71 specifically includes a sleeve and a heating wire disposed in the sleeve. The sleeve forms an atomizing air channel 70, and the heating wire can be energized to heat and convert the aerosol matrix into aerosol. Of course, the heating wire can also be a heating mesh, heating plate, ceramic heating element, or other elements that can be energized to heat.

[0094] Specifically, the liquid guiding component can be liquid guiding cotton or a porous ceramic structure. The liquid guiding cotton can be made of any material with strong adsorption and good conductivity, such as polyester fiber cotton, organic cotton, or ceramic fiber cotton. Those skilled in the art can configure it according to actual needs.

[0095] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, a second sealing member 6 is also included. The second sealing member 6 is disposed between the first liquid storage chamber 11 and the second liquid storage chamber 51. The second sealing member 6 is provided with a fourth hole 61 and a fifth hole 62 arranged at intervals. The fourth hole 61 connects the first liquid storage chamber 11 and the second liquid storage chamber 51, and the fifth hole 62 connects the airflow hole 10 and the atomizing air passage 70.

[0096] In this embodiment, the second sealing member 6 can seal the first liquid storage chamber 11 and the second liquid storage chamber 51, reducing the risk of aerosol matrix leakage; the fourth hole 61 provided in the second sealing member 6 can connect the first liquid storage chamber 11 and the second liquid storage chamber 51, thereby guiding the aerosol matrix in the first liquid storage chamber 11 to the atomizing component 7. The atomizing component 7 can heat the aerosol matrix to form an aerosol, which can flow out along the atomizing air passage 70, the airflow hole 10, the third hole 42 and the suction hole 30 for consumption by the user.

[0097] In specific applications, the second sealing element 6 can be a sealing ring, a sealing gasket, or other sealing element. Preferably, the second sealing element 6 is a silicone sealing ring, which can tightly fit the cavity wall of the oil storage cavity. Those skilled in the art can choose according to actual needs, and this application does not limit it.

[0098] Understandably, in actual use, the aerosol matrix in the first liquid storage chamber 11 flows to the second liquid storage chamber 51 through the fourth hole 61. The liquid guide in the second liquid storage chamber 51 leads the aerosol matrix to the heating element 71. After the heating element 71 heats the aerosol matrix to form an aerosol, the aerosol can flow out sequentially through the atomizing air channel 70, the airflow hole 10, the third hole 42 and the suction hole 30 so that it can be ingested by the user.

[0099] Specifically, multiple fourth holes 61 can be provided, spaced apart, thereby increasing the amount of aerosol matrix flowing into the second liquid storage chamber 51, such as... Figure 2 and Figure 3 As shown, two fourth holes 61 can be provided, with the two fourth holes spaced apart on both sides of the fifth hole 62, so that the liquid guiding parts on both sides of the heating element 71 can have aerosol matrix flowing in.

[0100] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, an electronic atomizing device is also proposed, including a power supply component 8 and an atomizer as described in any of the above embodiments, wherein the power supply component 8 is used to supply power to the atomizer.

[0101] In the embodiments of this application, the electronic atomizing device includes the atomizer as described in any of the above embodiments, thereby the electronic atomizing device has the beneficial effects of the atomizer in any of the above embodiments, which will not be described again here.

[0102] It should be noted that the power supply component 8 can be fixedly connected to the atomizer or detachably connected. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on it.

[0103] In a specific application, the power supply component 8 includes a housing 81 and a battery 82 disposed inside the housing 81. The housing 81 is detachably connected to the housing 1, which facilitates the assembly and disassembly of the power supply component 8. The battery 82 can supply power to the heating element 71.

[0104] like Figure 3 and Figure 5 As shown, in some embodiments of this application, a second liquid-absorbing element 9 is also included. The second liquid-absorbing element 9 is disposed between the atomizing component 7 and the power supply component 8, thereby reducing the impact of aerosol matrix or condensate leakage from the atomizing component 7 on the normal use of the power supply component 8.

[0105] like Figure 4 and Figure 5 As shown, in some embodiments of this application, a liquid injection system is also proposed. The liquid injection system includes a liquid injection component 100, such as the atomizer described in any of the above embodiments, or the electronic atomizing device described in the above embodiments. The liquid injection component 100 is used to apply external force to the sealing part 21 to release the sealing of the liquid injection hole 12 and inject the aerosol matrix into the first liquid storage chamber 11.

[0106] In this application embodiment, the liquid injection system includes the atomizer as described in any of the above embodiments, thereby the liquid injection system has the beneficial effects of the atomizer described in any of the above embodiments, which will not be elaborated here.

[0107] In specific applications, the injection component 100 can be a syringe, injection bottle, injection pump, etc., which can apply external force to the sealing part 21 to release the blockage of the injection hole 12, thereby injecting the aerosol matrix into the first liquid storage chamber 11. Those skilled in the art can choose according to actual needs, and this application does not limit it.
