Description

Technical Field

[0001] This invention belongs to the technical field of atomization equipment, and particularly relates to an atomizer and an atomization device using the atomizer. Background Technology

[0002] The atomizing device includes an atomizer and a power supply for the atomizer. The atomizer internally comprises a liquid storage chamber, an airflow channel, and an atomizing core. The power supply powers the atomizing core, thereby driving the atomizing core to heat and atomize, so as to atomize the solution adsorbed from the liquid storage chamber into an aerosol for the user to inhale.

[0003] However, in traditional atomizers, the atomizing core is directly connected to the liquid storage chamber. During transportation and preparation, the liquid-absorbing substrate inside the atomizing core is immersed in the liquid storage chamber for a long time, which can easily lead to leakage and oxidation and deterioration of the liquid to be atomized.

[0004] Therefore, a liquid-gas separation atomizer has gradually emerged on the market. It features a sealed isolation sleeve, with the atomizing core and the mist outlet tube forming the airflow channel connected to each end of the sleeve. An internal pull cord is installed within the sleeve, passing through the mist outlet tube and extending to the outside. During transportation and preparation, the liquid inlet on the side wall of the atomizing core is covered by the sealing isolation sleeve. When the user uses the device, pulling the cord slides the sealing isolation sleeve towards the mist outlet tube, thus connecting the liquid inlet on the side wall of the atomizing core with the liquid storage chamber. This effectively prevents leakage and oxidation of the solution to be atomized inside the storage chamber during transportation and preparation.

[0005] However, the above solution also has the problem that the atomizing core and the atomizing tube are connected by a sealed isolation sleeve. A part of the air passage inside the atomizer is surrounded by the inner wall of the sealed isolation sleeve. During atomization, the high-temperature airflow is prone to producing condensate when it encounters the sealed isolation sleeve. Furthermore, during inhalation, the flexible sealed isolation sleeve will deform under negative pressure, resulting in differences in the inhalation taste. Summary of the Invention

[0006] The purpose of this application is to provide an atomizer that prevents leakage during transportation, reduces condensation without the need for sealing, and improves the consistency of taste.

[0007] To achieve the above objectives, firstly, the technical solution adopted in this application is: to provide an atomizer, comprising:

[0008] The main body has an internal liquid storage chamber and a mist outlet pipe that connects to the outside.

[0009] The atomizing core has a mist outlet end connected to the mist outlet tube, and the side wall of the atomizing core is provided with a liquid inlet hole. It has an atomizing component inside, which is used to atomize the atomizing liquid flowing in from the liquid inlet hole into aerosol.

[0010] The base is installed on the main body, and the upper end of the base is provided with a mounting part for installing the atomizing core and a clearance groove surrounding the mounting part. The bottom wall of the clearance groove is provided with a clearance hole that passes through the base.

[0011] A flexible seal is provided, with its upper end covering the outer peripheral surface of the atomizing core and sealing the liquid inlet, and its lower end sealing the opening of the clearance groove.

[0012] The drive control unit has one end for connecting to the lower end of the seal, and the other end extends into the relief groove and out of the base along the relief hole to form a drive control part. Under the action of external pulling force, the drive control part pulls the seal towards the relief groove to slide, so that the liquid inlet hole is exposed, and the seal located in the relief groove interference seals the groove opening of the relief groove.

[0013] Optionally, the drive control and the seal are integrally formed, and the connection between the drive control and the seal has a cut to form a thin-walled tensile portion.

[0014] Optionally, the atomizer also includes a sealing sleeve that is fitted onto the base and covers the upper surface of the base;

[0015] The sealing element includes an outer tube and an inner tube arranged concentrically, and a connecting plate that seals and connects the upper surfaces of the outer tube and the inner tube. The lower end of the outer tube is connected to the sealing sleeve, and the inner tube is used to cover the outer peripheral surface of the atomizing core. The lower end of the inner tube is connected to the drive control.

[0016] Optionally, the sealing sleeve and the sealing element are integrally formed.

[0017] Optionally, a shaping plate is also provided between the opposing surfaces of the outer tube and the inner tube.

[0018] Optionally, the lower end of the shaping plate is provided with a slit, and the edge of the relief groove is not covered by the outer tube and the sealing sleeve to form a slit.

[0019] When the drive control pulls the inner tube along the opening of the clearance groove toward the clearance groove, the shaping plate is cut along the cut opening corresponding to the cut portion.

[0020] Optionally, the thickness of the shaping plate is 0.2mm-1mm.

[0021] Optionally, when the inner tube is pulled by the drive control to contact the bottom wall of the avoidance groove, it abuts and is limited. The outer tube is pulled by the inner tube through the connecting plate toward the avoidance groove and fits against the outer wall of the atomizing core, and is located below the liquid inlet.

[0022] Optionally, the mounting part has an air inlet channel in the middle that connects to the internal air passage of the atomizing core, and the lower side wall of the mounting part has an air passage that connects to the inner wall of the relief hole. External airflow flows into the atomizing core through the relief hole and the air passage.

[0023] Secondly, this application also provides an atomizing device, including a power supply and the atomizer as described above, wherein the atomizer is installed on the power supply and is electrically connected to the power supply.

[0024] The beneficial effects of this application are as follows: By installing the two ends of the atomizing core onto the mist outlet tube of the main body and the mounting part of the base respectively, an atomizing air path is constructed. Then, by setting a flexible sealing element to wrap the outer peripheral surface of the atomizing core and cover the liquid inlet of the atomizing core, the liquid inlet of the atomizing core is effectively prevented from communicating with the liquid storage chamber during transportation and preparation, which would lead to leakage and easy oxidation and deterioration of the solution to be atomized through communication with the external airflow through the liquid inlet. Furthermore, by setting a clearance groove around the mounting part of the base, and setting a clearance hole in the bottom wall of the clearance groove, the lower end of the sealing element seals the opening of the clearance groove to prevent the solution inside the liquid storage chamber from flowing into the clearance groove. Finally, by setting a drive control to be connected to the lower end of the sealing element, and setting the drive control to extend into the clearance groove and extend out of the base from the clearance hole, it is used for users to pull. When the user uses it, the sealing element is pulled towards the clearance groove, so that the liquid inlet of the atomizing core is exposed in the liquid storage chamber, realizing the liquid path conduction. This achieves liquid-gas separation to prevent leakage, while effectively avoiding the phenomenon of easy leakage and poor taste consistency caused by using a sealed inner wall for part of the atomizing gas path.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please see Figures 1 to 8 This application provides an atomizer 100, which includes a main body 10, an atomizing core 30, and a base 50. The main body 10 has an opening at one end and a mist outlet at the other end. The base 50 is installed on the open end of the main body 10 and seals the opening, thereby forming a liquid storage chamber 12 inside the main body 10. A mist outlet tube 11 is provided around the mist outlet inside the main body 10. The mist outlet tube 11 can be a tube integrally formed with the main body 10 or a steel tube pressed into the mist outlet. One end of the atomizing core 30 is connected to the mist outlet tube 11. The base 50 has a mounting part 52 for mounting the atomizing core 30. The mounting part 52 is a protrusion integrally formed with the base 50. The protrusion has an air intake channel 522 communicating with the outside in the middle. The lower end of the atomizing core 30 is sleeved outside the protrusion or inserted into the air intake channel 522 on the protrusion, thereby being installed on the base 50. External airflow flows into the atomizing core 30 through the air inlet channel 522, mixes with the solution to be atomized adsorbed from the liquid storage chamber 12 by the atomizing core 30, heats and atomizes it into a mist, and finally discharges it to the outside through the mist outlet pipe 11 for the user to inhale. The solution to be atomized can be e-liquid, a solution containing medicinal ingredients, or herbal extracts, etc., and is not limited here.

[0042] To prevent the solution in the storage chamber 12 from flowing into the atomizing core 30 through the inlet hole 31 on the side wall of the atomizing core 30 during transportation, which could lead to leakage or easy oxidation and deterioration of the solution to be atomized, the atomizer 100 in this embodiment further includes a flexible sealing element 70, for example, made of non-toxic silicone or rubber. The upper end of the sealing element 70 is sleeved on the outer peripheral surface of the atomizing core 30. Since the sealing element 70 is made of a flexible material, it has a certain elastic deformation property, thereby covering the outer peripheral surface of the atomizing core 30, sealing the inlet hole 31, and realizing liquid-gas separation.

[0043] At the same time, such as Figure 5As shown in this embodiment, the base 50 is provided with a clearance groove 53 surrounding the mounting portion 52, and the bottom wall of the clearance groove 53 is provided with a clearance hole 531 that penetrates the base 50. To prevent the solution to be atomized inside the liquid storage chamber 12 from leaking into the clearance groove 53, the lower end of the sealing member 70 seals the opening of the clearance groove 53. The specific sealing method can be to cover the opening of the clearance groove 53 or to be elastically interference-fitted into the opening of the sealing groove, etc., which is not limited here. At the same time, the lower end of the sealing member 70 is also connected to a drive control 90, and the other end of the drive control 90 extends into the clearance groove 53 and extends out of the base 50 along the clearance hole 531 to form a drive control portion. Under external pulling force, the drive unit pulls the sealing member 70 towards the recess groove 53, causing the liquid inlet 31 to protrude into the liquid storage chamber 12. Therefore, the solution to be atomized stored inside the liquid storage chamber 12 can flow into the atomizing core 30 through the liquid inlet 31 for atomization. The portion of the sealing member 70 pulled into the recess groove 53 elastically presses against the opening of the recess groove 53, thereby preventing the solution in the liquid storage chamber 12 from leaking out through the recess hole 531 after flowing into the recess groove 53.

[0044] Specifically, the drive control 90 and the seal 70 can be integrally molded from silicone, or an external drive tool, such as tweezers, can be used to insert into the clearance groove 53 along the clearance hole 531 and clamp the seal 70 to apply force and pull it. In this embodiment, the drive control 90 and the seal 70 are integrally molded from silicone, and the connection between the drive control 90 and the seal 70 has a cut 91 to form a thin-walled breakage portion 92. When the seal 70 abuts against the bottom wall of the clearance groove 53, it is limited. When further force is applied to the drive control 90, the thin-walled breakage portion 92 at the connection between the drive control 90 and the seal 70 breaks under force due to the thin wall thickness at the cut 91, causing the drive control 90 to detach from the base 50. Specifically, the cut 91 forming the thin-walled breakage portion 92 is opened on the side of the drive control 90 facing the atomizing core 30, thereby avoiding interference and contact between the cut 91 of the thin-walled breakage portion 92 and the slit portion 532 when pulled.

[0045] Specifically, to prevent the thin-walled fracture portion 92 from breaking before the seal is pulled to the predetermined position due to excessive contact friction between the drive control 90 and the clearance hole 531 when the seal is pulled, in this embodiment, the size of the drive control 90 is smaller than the size of the clearance hole 531. Simultaneously, to prevent the seal 70 from being subjected to force on one side when the drive control pulls it, causing deformation and leakage on the other side, in this embodiment, two drive controls 90 are used. These two drive controls 90 are respectively connected to opposite sides of the lower end of the seal 70, thereby applying force to both sides of the lower end of the seal 70 simultaneously. This effectively prevents leakage caused by slippage of the seal 70 under unilateral force, and also prevents the drive control 90 and the seal 70 from easily breaking due to excessive pulling force required when applying force on one side.

[0046] Furthermore, such as Figures 1 to 4 As shown, the atomizer 100 also includes a sealing sleeve 60, which is fitted onto the outer peripheral surface of the base 50 and covers the upper surface of the base 50. This ensures that when the base 50 is inserted into the opening of the main body 10, the outer peripheral surface of the base 50 and the inner wall of the opening of the main body 10 form an interference seal, preventing the solution inside the liquid storage chamber 12 from leaking out through this gap. The sealing element 70 includes an outer tube 72 and an inner tube 71 arranged concentrically, and a connecting plate 73 that seals and connects the upper surfaces of the outer tube 72 and the inner tube 71. The lower end of the outer tube 72 is integrally molded with the sealing sleeve 60 using silicone material. The inner tube 71 is used to cover the outer peripheral surface of the atomizing core 30, and the lower end of the inner tube 71 is connected to the drive control 90. Here, the sealing element 70, sealing sleeve 60, and drive control 90 are integrally molded from silicone, allowing the user to attach the sealing element 70 to the atomizing core 30 simultaneously with the installation of the sealing sleeve 60. Compared to the traditional pull-cord type oil distribution structure, the sealing sleeve 60 for the base 50 and the sealing element 70 for the atomizing core 30 are separate, effectively reducing installation steps and eliminating the need for two sets of molds to separately manufacture the two components, thus facilitating processing and production and improving efficiency. Furthermore, the integral molding of the sealing sleeve 60 and sealing element 70 completely covers the upper surface of the base 50, thus completely eliminating the possibility of solution leaking from the storage chamber 12 through the clearance groove 53.

[0047] Specifically, such as Figure 4 Combination Figure 6 As shown, the two drive control components 90 are plate-shaped and have an arc that matches the lower end of the seal 70, thereby increasing the connection area with the seal 70, enhancing the stability of the connection, and preventing the thin-walled tensile portion 92 from breaking during the pulling of the seal 70. Furthermore, the plate-shaped drive control components 90 facilitate the user to squeeze both drive control components 90 simultaneously to apply pulling force.

[0048] Furthermore, such as Figure 1 Combination Figure 7 As shown, the sealing element 70 is made of flexible silicone. To prevent the inner tube 71 and outer tube 72 from flanging due to friction during assembly of the sealing element 70 and the atomizing core 30, in this embodiment, a shaping plate 74 is provided between the opposing surfaces of the outer tube 72 and the inner tube 71. The lower end of the shaping plate 74 has a slit 741, and the edge controlled by the relief groove 53 is not covered by the contact between the outer tube 72 and the sealing sleeve 60, thus forming a slit 532. When the drive control pulls the inner tube 71 along the opening of the relief groove 53 toward the relief groove 53, the shaping plate 74 is cut along the slit 741 corresponding to the slit 532, thereby separating the outer tube 72 and the inner tube 71, and pulling the inner tube 71 into the relief groove 53. The thickness D of the shaping plate 74 is between 0.2 mm and 1 mm. In this embodiment, the thickness of the shaping plate 74 is 0.2 mm. It is understood that in other embodiments, 0.3 mm, 0.5 mm, 1 mm, etc., may also be selected, depending on the hardness of the silicone, and all of these are within the scope of protection of this application.

[0049] Specifically, such as Figure 1 Combination Figure 2 As shown, the depth of the recess 53 is greater than the height of the inner tube 71 and less than or equal to the sum of the height of the outer tube 72 and the height of the inner tube 71. When the inner tube 71 is pulled by the drive control 90 to contact the bottom wall of the recess 53, it abuts and is limited. At this time, the outer tube 72 is pulled by the inner tube 71 through the connecting plate 73 to move into the recess 53 and fit against the outer wall of the atomizing core 30, and is located below the liquid inlet 31. This ensures that the liquid inlet 31 can be exposed in the liquid storage chamber 12. When the lower end of the inner tube 71 abuts against the bottom wall of the recess 53, the drive control 90 is pulled further to break the thin-walled fracture portion 92. At this time, the outer tube 72 is flush with or slightly higher than the opening of the recess 53, thereby effectively preventing the solution in the liquid storage chamber 12 from entering the recess 53.

[0050] Furthermore, such as Figure 1 or Figure 2 As shown, the lower side wall of the air intake channel 522 is provided with an air passage 521 that connects to the inner wall of the relief hole 531. External airflow flows into the atomizing core 30 through the relief hole 531 and the air passage 521, thus eliminating the need for additional air intake holes, making the product appearance more aesthetically pleasing, and providing more space on the back of the base 50 for arranging electrodes and magnets.

[0051] It is understood that in practical applications, the method of forming an airflow passage by opening an air passage 521 and a clearance hole 531 on the lower side wall of the air intake channel 522 is not limited to the above embodiment. For example, in other embodiments of this application, the method of directly opening a through hole on the bottom surface of the air intake channel 522 to connect with the outside is also within the scope of protection of this application.

[0052] Specifically, such as Figure 2 Combination Figure 5 As shown, the base 50 has a blind mounting hole 51 at its upper end. A protruding post protrudes from the bottom wall of the blind mounting hole 51 to form the mounting portion 52. The protrusion height of the post is less than the depth of the blind mounting hole 51. The lower end of the atomizing core 30 extends into the blind mounting hole 51 and is fitted onto the outer peripheral surface of the protruding post. A clearance groove 53 is formed between the outer peripheral wall of the atomizing core 30 and the inner wall of the blind mounting hole 51. This ensures that the outer tube 72 and inner tube 71 of the sealing element 70 firmly cover the outer wall of the atomizing core 30 during pulling. This prevents the sealing element 70 from becoming unrestricted on the outside of the blind mounting hole 51 when the protruding post protrudes, thus avoiding deformation during pulling.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
