Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular provides a seal and an atomizer. Background Art

[0002] Atomizers heat and atomize a liquid aerosol matrix to generate an inhalable aerosol. Currently, atomizers typically feature refills. When the atomizing liquid in the reservoir inside the atomizer is depleted, the user can refill it for reuse, saving costs and enriching the user experience.

[0003] In the prior art, some atomizers are connected to a seal for opening a liquid filling port at one end having a mouthpiece. The user can perform the liquid filling operation through the liquid filling port by opening the seal. However, the actual liquid filling operation has the following disadvantages: when the user has filled the liquid and then covers the above-mentioned seal, the seal has a downward compression stroke, which can easily press the excess air in the seal into the liquid storage chamber through the liquid filling port, thereby increasing the air pressure in the liquid storage chamber, and forcing part of the atomized liquid in the liquid storage chamber into the atomizing device, thereby causing the atomized liquid to leak. At the same time, it can also cause the user to easily inhale the atomized liquid when smoking, resulting in a poor user experience. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a seal and an atomizer, aiming to solve the problem of leakage in the existing atomizer due to changes in air pressure inside the liquid storage chamber during the process of closing the seal after filling the liquid, resulting in poor user experience.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In a first aspect, an embodiment of the present application provides a seal for plugging and cooperating with the air pipe of a nebulizer, wherein the seal has an air outlet channel extending therethrough, and the air outlet channel has a plug-in end for plugging with the air pipe; the seal is provided with at least one air relief groove on the inner wall surface of the air outlet channel, the air relief groove has an air inlet end for air intake, and the air inlet end extends through the plug-in end.

[0007] The beneficial effect of the present application is that by setting an air relief groove in the air outlet channel of the seal, when the user completes filling the liquid storage chamber and then covers the above-mentioned seal, although the seal has a compression stroke, the gas in the liquid storage chamber can be discharged to the outside of the main shell through the air relief groove, thereby reducing the pressure change in the liquid storage chamber and preventing leakage.

[0008] In some embodiments, the seal is provided with an annular protrusion on the inner wall surface of the air outlet channel for interference fit with the air pipe, and the air relief groove has an air outlet end away from the air inlet end, and the air outlet end is arranged between the annular protrusion and the plug end.

[0009] By adopting the above technical solution, effective sealing is achieved through the interference fit between the annular protrusion and the trachea, and an air relief groove is formed between the annular protrusion and the plug-in end, so that gas can be discharged through the air relief groove before the seal and the trachea form a complete seal.

[0010] In some embodiments, the annular protrusion includes a straight edge portion for abutting against the trachea and inclined portions formed at opposite ends of the straight edge portion.

[0011] By adopting the above technical solution, the cross-section of the annular protrusion is trapezoidal, and the straight edge portion provides a longer sealing section between the air pipe and the sealing member, which is beneficial to improving the sealing performance and reducing leakage.

[0012] In some embodiments, the sealing component is formed with an outwardly expanding portion at the plug-in end of the air outlet channel, the outwardly expanding portion being flared relative to the air outlet channel.

[0013] By adopting the above technical solution, an outward expansion portion is provided to facilitate the insertion of the air pipe of the atomizer, and an air relief groove is formed on the outward expansion portion, so that when the seal is matched with the atomizer, the air in the atomizer can be discharged from the air relief groove, so that the atomized liquid in the atomizer will not overflow due to pressure changes.

[0014] In some embodiments, the outwardly expanded portion includes a rounded corner or a chamfered corner provided at the plug end of the air outlet channel.

[0015] By adopting the above technical solution, the plug-in end is expanded outward by setting a rounded corner or a chamfer, and the structure is simple.

[0016] In some embodiments, the air relief groove is extended along the length direction of the air outlet channel; the air inlet end of the air relief groove extends to the outward expansion portion, and the air outlet end of the air relief groove extends to the annular protrusion.

[0017] By adopting the above technical solution, the air relief groove is in the shape of an elongated strip. Before the air pipe and the annular protrusion form an interference seal, the gas in the liquid storage cavity can be discharged through the air relief groove to balance the air pressure.

[0018] In some embodiments, a plurality of the air relief grooves are distributed on the inner wall surface of the air outlet channel at circumferential intervals.

[0019] By adopting the above technical solution, multiple air release grooves are set up to increase the speed at which the gas in the liquid storage chamber is discharged to the outside, ensuring that the excess air in the liquid storage chamber can be discharged to the outside in time.

[0020] In a second aspect, an embodiment of the present application further provides an atomizer, comprising a main shell, a nozzle arranged at the top of the main shell, and the sealing member; the main shell has a liquid storage chamber and an air tube arranged in the liquid storage chamber; the liquid storage chamber forms a liquid injection port surrounding the air tube at the top of the main shell, and the sealing member is configured to engage with the air tube and seal the liquid injection port.

[0021] The beneficial effect of the atomizer of the present application is that the liquid injection port is formed between the top of the main shell and the air pipe, and then the cross-sectional diagram of the top of the main shell except the air pipe can be injected with liquid, thereby maximizing the injection area, thereby realizing large-caliber liquid injection, reducing the difficulty of liquid injection, and reducing the occurrence of leakage during the liquid injection process.

[0022] In some embodiments, a cap body is provided at the top end of the trachea, and the cap body has a support surface, and an opening communicating with the air outlet channel is formed on the support surface.

[0023] By adopting the above technical solution and providing a cap body with rounded corners, the support area of ​​the air pipe and the silicone plug of the suction nozzle is increased, thereby preventing the silicone plug of the suction nozzle from sinking during and after assembly.

[0024] In some embodiments, the diameters of the trachea at opposite ends in the length direction are equal.

[0025] By adopting the above technical solution, the diameters of the two ends of the trachea are the same. When the trachea deviates in the liquid storage cavity, the liquid storage volume in the liquid storage cavity will not change, so that no pressure change will occur inside the liquid storage cavity, preventing leakage.

[0046] Atomizers heat and atomize a liquid aerosol matrix to generate an inhalable aerosol. Currently, atomizers typically feature refills. When the atomizing liquid in the reservoir inside the atomizer is depleted, the user can refill it for reuse, saving costs and enriching the user experience.

[0047] In the prior art, some atomizers are connected to a seal for opening a liquid filling port at one end having a mouthpiece. The user can perform the liquid filling operation through the liquid filling port by opening the seal. However, the actual liquid filling operation has the following disadvantages: when the user has filled the liquid and then covers the above-mentioned seal, the seal has a downward compression stroke, which can easily press the excess air in the seal into the liquid storage chamber through the liquid filling port, thereby increasing the air pressure in the liquid storage chamber, and forcing part of the atomized liquid in the liquid storage chamber into the atomizing device, thereby causing the atomized liquid to leak. At the same time, it can also cause the user to easily inhale the atomized liquid when smoking, resulting in a poor user experience.

[0048] Based on this, in order to solve the above problems, the present application designs a seal, which sets an air relief groove in the air outlet channel of the seal. When the user completes the filling of the liquid storage chamber and then covers the seal, although the seal has a compression stroke, since the bottom end of the air relief groove passes through the plug-in end, even if the air pipe is inserted into the air outlet channel, the gas in the liquid storage chamber can still be discharged to the outside through the air relief groove, thereby reducing the pressure change in the liquid storage chamber and preventing leakage.

[0049] Please refer to Figure 4 、 Figure 5 The embodiment of the present application provides an atomizer 100, which includes a main shell 101, a nozzle 102 arranged at the top of the main shell 101, and a sealing member 200; the main shell 101 has a liquid storage chamber 3 and an air pipe 4 arranged in the liquid storage chamber 3, and the liquid storage chamber 3 forms a liquid injection port 5 surrounding the air pipe 4 at the top of the main shell 101, and the sealing member 200 is configured to be plugged into and matched with the air pipe 4 and seal the liquid injection port 5.

[0050] Specifically, the nozzle 102 and the seal 200 are both detachably connected to the main shell 101. When it is necessary to fill the liquid storage chamber 3 of the atomizer 100, the nozzle 102 and the seal 200 are detached from the main shell 101, and the liquid storage chamber 3 can be filled from the top of the main shell 101 through the liquid filling port 5.

[0051] The liquid storage chamber 3 is formed between the main housing 101 and the trachea 4. The liquid storage chamber 3 is used to absorb / store the aerosol matrix. The liquid storage chamber 3 can be a hollow cavity, and the aerosol matrix is ​​directly stored in the liquid storage chamber 3; or a liquid storage cotton can be set in the liquid storage chamber 3, and the aerosol matrix is ​​absorbed on the liquid storage cotton. Figure 4 The liquid storage chamber 3 passes through the top of the main shell 101, and the liquid injection port 5 is formed between the top of the main shell 101 and the air pipe 4. Then, the cross-sectional diagram of the top of the main shell 101 except the air pipe 4 can be injected with liquid, thereby maximizing the injection area and realizing large-caliber injection, reducing the difficulty of injection and reducing the occurrence of leakage during the injection process.

[0052] refer to Figure 1 、 Figure 2 、 Figure 3 In some embodiments, the seal 200 has a penetrating air outlet channel 6, the air outlet channel 6 has a plug-in end 601 that is plugged into the trachea 4, and the seal 200 is provided with at least one air relief groove 7 on the inner wall surface of the air outlet channel 6, the air relief groove 7 has an air inlet end 701 for air intake, and the air inlet end 701 penetrates to the plug-in end 601.

[0053] Specifically, refer to Figure 4 、 Figure 6During the assembly of the seal 200 and the main shell 101, the seal 200 covers the liquid injection port 5, and the air pipe 4 is inserted upward into the air outlet channel 6 from the plug-in end 601 of the air outlet channel 6; the air inlet end 701 is located at the bottom end of the air discharge groove 7.

[0054] The seal 200 of the present application is provided with an air relief groove 7 in the air outlet channel 6 of the seal 200. When the user completes the filling of the liquid storage chamber 3 and then covers the seal 200, although the seal 200 has a compression stroke, since the air inlet end 701 of the air relief groove 7 passes through the plug-in end 601, even if the air pipe 4 is inserted into the air outlet channel 6, the gas in the liquid storage chamber 3 can still be discharged to the outside through the air relief groove 7, thereby reducing the pressure change in the liquid storage chamber 3 and preventing the occurrence of leakage.

[0055] It is understood that the contour shape of the air relief groove 7 on the inner wall surface of the air outlet channel 6 can be, but is not limited to, a strip, an arc, or a curve, so as to ensure that the gas in the liquid storage chamber 3 can enter the air relief groove 7 through the air inlet end 701. The number of air relief grooves 7 can also be one or more, and is not specifically limited here.

[0056] refer to Figure 1 、 Figure 3 、 Figure 6 In some embodiments, the seal 200 is provided with an annular protrusion 8 on the inner wall surface of the air outlet channel 6 for interference fit with the trachea 4, and the air relief groove 7 has an air outlet end 702 away from the air inlet end 701, and the air outlet end 702 is arranged between the annular protrusion 8 and the plug end 601.

[0057] Specifically, the air pipe 4 is inserted into the air outlet channel 6 of the sealing member 200 through the plug-in end 601 of the air outlet channel 6 , and finally the air pipe 4 is interference-fitted with the annular protrusion 8 , thereby achieving effective sealing between the air pipe 4 and the sealing member 200 .

[0058] It can be understood that the air outlet end 702 of the air relief groove 7 is arranged between the annular protrusion 8 and the plug-in end 601, so before the seal 200 and the trachea 4 form a complete seal, the gas in the liquid storage chamber 3 can still be discharged through the air relief groove 7; then, during the process of connecting the seal 200 with the main shell 101, before the seal 200 and the trachea 4 form a complete seal, the excess air in the liquid storage chamber 3 will be discharged through the air relief groove 7, reducing the pressure change in the liquid storage chamber 3 and preventing leakage.

[0059] Specifically, the air outlet end 702 can be set close to the annular protrusion 8 to extend the travel of the gas through the air relief groove 7; the air outlet end 702 can also be set at other positions between the annular protrusion 8 and the plug-in end 601 to ensure that the air in the liquid storage chamber 3 can be discharged through the air relief groove 7 before the seal 200 and the trachea 4 form a complete seal. No specific limitation is made here.

[0060] refer to Figure 3 In some embodiments, the annular protrusion 8 includes a straight edge portion 801 and inclined portions 802 formed at opposite ends of the straight edge portion 801 .

[0061] Specifically, the length direction of the straight edge portion 801 is consistent with the length direction of the air outlet channel 6. After the trachea 4 is inserted into the air outlet channel 6 and forms an interference fit with the annular protrusion 8, the straight edge portion 801 will be in close contact with the trachea 4. There is a good contact length between the straight edge portion 801 and the trachea 4, forming a good sealing effect.

[0062] The inclined portion 802 is a chamfer or rounded corner formed at opposite ends of the straight edge portion 801 , which facilitates the air pipe 4 to pass through the annular protrusion 8 smoothly and prevents the pipe opening of the air pipe 4 from scraping the sealing member 200 .

[0063] In some embodiments, reference Figure 3 The cross-section of the annular protrusion 8 is trapezoidal, and the straight edge 801 provides a longer sealing section between the trachea 4 and the sealing member 200, which is beneficial to improving the sealing performance and reducing leakage.

[0064] refer to Figure 1 、 Figure 3 In some embodiments, the sealing member 200 is formed with an outwardly expanding portion 9 at the plug-in end 601 of the air outlet channel 6 , which is outwardly expanding relative to the air outlet channel 6 .

[0065] In some embodiments, the outward expansion portion 9 includes a rounded corner or a chamfered corner provided at the plug-in end 601 of the air outlet channel 6 . The outward expansion portion 9 is provided to facilitate the plug-in connection between the sealing member 200 and the trachea 4 .

[0066] Specifically, during the process of plugging the seal 200 into the trachea 4, there is a gap between the trachea 4 and the outward expansion portion 9, and the end of the air relief groove 7 away from the annular protrusion 8 is formed on the outward expansion portion 9, that is, there is a gap between the end of the air relief groove 7 away from the annular protrusion 8 and the trachea 4; the air in the liquid storage chamber 3 can be discharged smoothly through the air relief groove 7, thereby reducing the pressure change in the liquid storage chamber 3 and preventing the atomized liquid in the liquid storage chamber 3 from overflowing due to pressure changes.

[0067] refer to Figure 1 、 Figure 3 In some embodiments, the air relief groove 7 is extended along the length direction of the air outlet channel 6; the air inlet end 701 of the air relief groove 7 extends to the outward expansion portion 9, and the air outlet end 702 of the air relief groove 7 extends to the annular protrusion 8.

[0068] Specifically, the contour shape of the air relief groove 7 on the inner wall surface of the air outlet channel 6 is a long strip, that is, the air relief groove 7 extends from the annular protrusion 8 to the outward expansion part 9, and then the gas in the liquid storage chamber 3 can be discharged through the air relief groove 7 until the air pipe 4 and the annular protrusion 8 form an interference seal, thereby extending the distance of the gas passing through the air relief groove 7 as much as possible, thereby maximizing the effect of balancing the air pressure.

[0069] refer to Figure 1 In some embodiments, a plurality of air relief grooves 7 are distributed on the inner wall surface of the air outlet channel 6 at circumferential intervals.

[0070] It can be understood that a plurality of air release grooves 7 are provided to increase the speed at which the gas in the liquid storage chamber 3 is discharged to the outside, thereby ensuring that the excess air in the liquid storage chamber 3 can be discharged to the outside in a timely manner.

[0071] refer to Figure 4-Figure 7 In some embodiments, a cap body 10 is provided at the top of the trachea 4 . The cap body 10 has a support surface 1001 . An opening 1002 communicating with the air outlet channel 6 and the trachea 4 is formed on the support surface 1001 .

[0072] It can be understood that the cap body 10 is sleeved on the top end of the trachea 4, and the cap body 10 has a support surface 1001. The cap body 10 can isolate the top end of the trachea 4 from the seal 200. There is a good supporting contact area between the cap body 10 and the seal 200, as well as between the cap body 10 and the annular protrusion 8, to prevent the seal 200 from being scratched by the trachea 4 during the assembly and extrusion process of the seal 200 and the trachea 4, thereby improving the structural stability.

[0073] The opening 1002 is connected between the gas outlet channel 6 and the trachea 4 and does not affect the gas flow.

[0074] refer to Figure 5 In some embodiments, the diameters of the trachea 4 at opposite ends in the length direction are equal.

[0075] It can be understood that the air tube 4 is disposed within the liquid storage chamber 3, with the upper and lower ends of the air tube 4 located at the top and bottom ends of the liquid storage chamber 3, respectively. In some existing atomizers 100, an atomizer core 11 is disposed within the bottom of the air tube 4, and the relative displacement between the air tube 4 and the liquid storage chamber 3 in the axial direction of the air tube 4 is adjusted to allow the liquid in the liquid storage chamber 3 to communicate with or be separated from the atomizer core 11. The liquid storage volume of the liquid storage chamber 3 depends on the enclosed volume between the outer wall of the air tube 4 and the inner wall of the main housing 101. The air tube 4 of the present application has equal diameters at opposite ends in the longitudinal direction, and the air tube 4 is cylindrical in structure. That is, when the air tube 4 is displaced in the axial direction relative to the liquid storage chamber 3, the liquid storage volume within the liquid storage chamber 3 does not change, and thus no pressure change occurs within the liquid storage chamber 3, thereby preventing leakage.

[0076] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
