Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to an atomization device of an electronic cigarette. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes. Like traditional cigarettes, electronic cigarettes can produce gases containing nicotine, tar and other substances. Users can get a feeling that is highly similar to smoking traditional cigarettes by purchasing and using them. The smoke produced by electronic cigarettes is formed by atomizing smoke oil containing substances similar to cigarettes. The atomization equipment installed inside the electronic cigarette atomizes the smoke oil containing nicotine into steam through heating and other methods for users to inhale. It is often used as a substitute for cigarettes or a transitional product for users to quit smoking. Compared with cigarettes, electronic cigarettes have the advantages of controllable smoke composition and less smoke. They are not prone to fires caused by littering of cigarette butts, and are safer. By controlling the smoke composition and the amount of smoke, the damage to the human body caused by smoking can be minimized, and the secondhand smoke produced by smokers can also be reduced. They are deeply favored by consumers.

[0003] In traditional electronic cigarette atomization devices, the heating core and the base are usually connected by threads.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0042] Reference Figure 1-8 The present invention provides an electronic cigarette 1000, which includes an atomizing device 100 and a power supply device 300. When the atomizing device 100 is installed on the power supply device 300, an electrical connection is established with the power supply device 300; a user drives the power supply device 300 to supply power to the atomizing device 100, so that the smoke liquid inside the atomizing device 100 is atomized at high temperature to generate smoke for the user to inhale.

[0043] Specifically, Figure 2 As shown, in an embodiment of the present invention, the atomization device 100 includes a base 10 and a heating core component 30, the base 10 is provided with an installation cavity 11 for accommodating the heating core component 30, the heating core component 30 includes a first portion 31 for interference fitting in the installation cavity 11 and a second portion 32 exposed from the installation cavity 11, and the heating core component 30 is provided with at least one hook hole 321 in the second portion 32 for the external disassembly device 200 to be inserted.

[0044] The present invention provides an installation cavity 11 for accommodating the heating core component 30 on the base 10 of the atomizing device 100, and then inserts the first part 31 of the heating core component 30 into the installation cavity 11 by interference fit. Compared with the traditional method of installing the atomizing core component on the base 10 by threaded rotation, the installation is more convenient and effectively avoids the direct friction between the heating core component 30 and the base 10 during rotation, which may cause damage to the contact conductive part. At the same time, the second part 32 of the heating core component 30 exposed from the installation cavity 11 is also provided with a hook hole 321. When disassembling, the external disassembly device 200 is inserted into the hook hole 321 to facilitate the application of force, thereby avoiding the phenomenon that the heating core component 30 is attached with oil and causes slipping and difficulty in disassembly.

[0045] Specifically, in the embodiment of the present invention, when the heating core component 30 is installed in the installation cavity 11, part of it is higher than the installation cavity 11, so that part of the outer peripheral surface of the heating core component 30 is exposed from the installation cavity 11 to form the second part 32, and at least one hook hole 321 is correspondingly provided. Here, by providing the hook hole 321 on the outer peripheral surface of the heating core component 30, it is possible to effectively prevent oil from penetrating into the hook hole 321, resulting in the phenomenon of the accumulation of smoke oil and dirt, which is inconvenient to clean. At the same time, the outer peripheral surface of the heating core component 30 referred to here is not limited to referring to the heating core component 30 being cylindrical. When the heating core component 30 is in other cubic shapes, the outer peripheral surface refers to the side wall of the heating core component 30, etc., which all fall within the protection scope of the present invention.

[0046] It is understandable that in actual application, the heat generating core 30 is not limited to the above embodiment, and is designed to be partially higher than the installation cavity 11. For example, in other embodiments of the present invention, Figure 1 or Figure 2 As shown, in the embodiment of the present invention, at least one window 12 in communication with the installation cavity 11 may be provided on the side wall of the base 10, so that part of the outer peripheral surface of the heating core component 30 is exposed from the at least one window 12 to form the second part 32. Here, by providing a window 12 on the side wall of the base 10 to expose part of the outer peripheral surface of the heating core component 30 to the outside to form the second part 32, it is effectively prevented that the heating core component 30 is higher than the outside of the installation cavity 11, resulting in a large height difference between the outer wall of the heating core component 30 and the end surface of the base 10 to form a gap, which is easy to accumulate smoke liquid or condensed water.

[0047] Furthermore, if Figure 2 or Figure 4As shown, in the embodiment of the present invention, in order to ensure that the hook hole 321 is exposed from the window 12 when the heating core component 30 is installed in the installation cavity 11, in the embodiment of the present invention, at least one positioning protrusion 33 is also provided on the heating core component 30, and at least one positioning groove 13 is correspondingly provided on the base 10. The heating core component 30 is inserted into the installation cavity 11 with the at least one positioning protrusion 33 facing the at least one positioning groove 13, so that the at least one hook hole 321 is exposed from the at least one window 12.

[0048] Specifically, Figure 2 As shown, in the embodiment of the present invention, by extending one end of the at least one window 12 to the surface where the cavity opening of the installation cavity 11 is located so as to be exposed to the outside, an insertion port 121 for inserting the at least one positioning protrusion 33 is formed, so that the at least one window 12 forms the at least one positioning groove 13. At this time, the side wall of the positioning protrusion 33 exposed from the window 12 forms the second part 32, and the hook hole 321 is correspondingly opened. By not having to set up an additional positioning groove 13, the production cost is effectively saved. At the same time, one end of the window 12 extends to the surface where the cavity opening of the installation cavity 11 is located so as to be exposed, which effectively facilitates the user to observe the position of the window 12 and facilitates the installation of the external disassembly device 200.

[0049] Specifically, Figure 2 As shown, in the embodiment of the present invention, when the at least one positioning protrusion 33 is inserted into the at least one window 12, the protruding end face of the at least one positioning protrusion 33 is smoothly adapted to the outer surface of the window 12; here, by adapting the positioning protrusion 33 to the shape of the window 12, the hook hole 321 can be directly exposed from the outer peripheral surface of the base 10, thereby preventing the positioning protrusion 33 from being short and not completely filling the window 12, resulting in the hook hole 321 being located in the window 12, which is inconvenient to observe, and at the same time preventing the formation of a large space between the end face of the positioning protrusion 33 facing the opening of the window 12 and the opening of the window 12, resulting in the accumulation of smoke liquid.

[0050] Similarly, if Figure 2 , Figure 4 or Figure 5 As shown, in the embodiment of the present invention, the positioning protrusion 33 is arranged at the end of the heating core component 30, and when the positioning protrusion 33 is installed in the positioning groove 13, the top surface of the positioning protrusion 33 is flush with the notch of the positioning groove 13, thereby effectively preventing the positioning protrusion 33 and the notch of the positioning groove 13 from having a height difference, forming a certain space, causing the smoke liquid to accumulate and cause pollution.

[0051] Specifically, in order to facilitate the insertion of the at least one positioning protrusion 33 into the insertion opening 121 of the at least one window 12, in this embodiment, by setting the width of the insertion head end of the at least one positioning protrusion 33 to be smaller than the width of the insertion opening 121 of the at least one window 12, wedge-shaped or arc-shaped guide surfaces can be provided on both sides of the insertion head end of the at least one positioning protrusion 33 to make it smaller than the width of the insertion opening 121. Of course, wedge-shaped or arc-shaped guide surfaces can also be provided on the side wall of the opening of the insertion opening 121 to make it larger than the width of the insertion head end of the positioning protrusion 33. This makes the installation smoother and avoids the occurrence of abutment and difficult installation. At the same time, the end of the positioning protrusion 33 away from the head end is interference-fitted with the width of the window 12, effectively preventing the heating core 30 from shaking.

[0052] Specifically, Figure 2 or Figure 4 As shown, in the embodiment of the present invention, in order to facilitate the disassembly of the heating core 30, the number of the positioning protrusions 33 is two, and the two positioning protrusions 33 are symmetrically arranged on the outer peripheral surface of the heating core 30, and the base 10 is correspondingly provided with two windows 12. When the two positioning protrusions 33 are respectively inserted into the windows 12 along the insertion openings 121 of the two windows 12, the outer end surfaces facing the openings of the windows 12 form the second part 32, and the hook holes 321 are respectively opened. Here, the external disassembly device 200 includes a connecting rod 210 and hooks 220 located at both ends of the connecting rod 210. When disassembling, the two hooks 220 are respectively inserted into the hook holes 321 opened by the two positioning protrusions 33 to apply force to both sides of the heating core 30 at the same time. This avoids the phenomenon that the disassembly is easy to be offset and abutted due to the unilateral application of force, resulting in large friction and difficulty in disassembly.

[0053] It can be understood that, in actual application, the two positioning protrusions 33 are not limited to the manner in which they are symmetrically arranged on the heating core component 30 in the above-mentioned embodiment. For example, in other embodiments of the present invention, the two positioning protrusions 33 can also be arranged on two adjacent side walls or other two side walls of the heating core component 30. It is only necessary to bend the connecting rod 210 of the external disassembly device 200 accordingly to achieve multi-point force application to the heating core component 30. All methods that facilitate disassembly are within the protection scope of the present invention.

[0054] Similarly, the number of the positioning protrusions 33 is not limited to two, for example, it can also be three, four, etc. to achieve multi-point force application on the heating core component 30, and the method for facilitating disassembly belongs to the protection scope of the present invention and will not be elaborated here.

[0055] It is understandable that if Figure 6As shown, in actual use, the method of opening the hook hole 321 on the outer surface of the heating core component 30 is not limited to the method in the above-mentioned embodiment. For example, in other embodiments of the present invention, the second part 32 can be formed by exposing part of the surface of the heating core component 30 from the cavity opening of the installation cavity 11, and at least one hook hole 321 is opened accordingly, and a hanging rod 322 is provided in the at least one hook hole 321 for hooking by the external disassembly device 200, which also falls within the protection scope of the present invention.

[0056] Specifically, Figure 2 As shown, in an embodiment of the present invention, in order to facilitate the insertion of the heating core component 30 into the installation cavity 11, in this embodiment, the outer diameter of the first part 31 of the heating core component 30 gradually increases from one end first inserted into the installation cavity 11 to the other end later inserted into the installation cavity 11, so that the clearance is matched during the initial insertion, which is convenient for positioning, and the insertion process continues to tighten, thereby completing the fixed installation and effectively preventing the occurrence of abutment during the initial insertion.

[0057] It is understandable that in actual application, the outer diameter of the first part 31 is not limited to the above-mentioned embodiment. For example, in other embodiments of the present invention, a wedge-shaped or arc-shaped guide portion may be provided at the head end of the heating core 30 inserted into the installation cavity 11, or a wedge-shaped or arc-shaped guide portion may be provided at the cavity opening of the installation cavity 11 to facilitate the insertion of the heating core 30, which are all within the protection scope of the present invention.

[0058] Furthermore, if Figure 3 or Figure 5 As shown, in the embodiment of the present invention, in order to prevent the heating core component 30 from being inserted into the installation cavity 11 and causing air suffocation and difficulty in pressing in, in the present embodiment, the heating core component 30 is further provided with an air passage 35, one end of the air passage 35 forms a first air hole 351 on the end face of the heating core component 30 at the insertion head end, and the other end is provided with a second air hole 352 on the surface of the heating core component 30 to communicate with the air path of the external space of the installation cavity 11. When the heating core component 30 is inserted into the installation cavity 11, the gas in the installation cavity 11 can flow into the air passage 35 through the first air hole 351, and then flow out to the outside through the second air hole 352, thereby effectively preventing the phenomenon of air suffocation and unsmooth installation caused by the inability to eliminate the air flow inside the installation cavity 11.

[0059] Specifically, the second air hole 352 can be opened in the second part 32 to be connected with the external air path. For example, it can be opened on the surface of the heating core component 30 exposed from the cavity opening of the installation cavity 11; for example, the hook hole 321 can be designed to be connected with the air path of the air passage 35 to form the second air hole 352, etc.

[0060] It is understandable that in actual application, the method of opening an air passage 35 in the heating core component 30 for exhaust is not limited to the above-mentioned embodiment. For example, in other embodiments of the present invention, a method of opening an air leakage hole (not shown) in the base 10 can also be adopted. For example, the base 10 can be provided with an air leakage hole connected to the outside world on the cavity wall facing the cavity opening of the installation cavity 11 to realize the method of exhausting the airflow.

[0061] Specifically, Figure 2 or Figure 5 As shown, in the embodiment of the present invention, the base 10 is further provided with a connecting column 15 in the middle of the installation cavity 11 facing the cavity opening, and a connecting hole 34 is correspondingly provided at the bottom end of the heating core 30. When the heating core 30 is installed in the installation cavity 11, the outer peripheral surface is interference-engaged with the inner wall of the installation cavity 11, and the connecting column 15 is interference-engaged with the connecting hole 34. Here, in this embodiment, by providing the connecting column 15 and the installation hole for plug-in connection, the interference contact area between the base 10 and the heating core 30 is effectively enhanced, thereby further improving the stability of the connection.

[0062] Specifically, Figure 2 , Figure 4 Combination Figure 5As shown, in the embodiment of the present invention, in this embodiment, the connecting column 15 is the first electrode of the base 10, the heating core component 30 includes a core seat 36 and a heating element 37, and when the heating element 37 is installed on the core seat 36, at least part of it is accommodated in the connecting hole 34; when the heating core component 30 is installed on the base 10, the connecting column 15 is inserted into the connecting hole 34 to establish an electrical connection with the heating element 37. Here, in this embodiment, the heating core component 30 includes a core seat 36 and a heating element 37, and the core seat 36 is provided with an atomizing groove 361, and the heating element 37 includes a heating part 371 and two conductive leads 372 electrically connected to the heating part 371, and the two conductive leads 372 are respectively installed at both ends of the heating part 371, and one end of the two conductive leads 372 away from the heating part 371 is installed on the core seat 36, so that the heating part 371 is mounted on the atomizing groove 361. One of the two conductive leads 372 is partially accommodated in the connection hole 34, and is electrically connected to the connection post 15 when the connection post 15 is inserted. This effectively facilitates user installation, and the connection post 15 can be electrically connected to the heating element 37 without the need for additional conductive connectors, effectively saving costs.

[0063] Specifically, Figure 2 As shown, in an embodiment of the present invention, the base 10 is made of conductive material, the connecting column 15 and the base 10 body are separated by an insulating member 16, and when the heating core component 30 is installed on the base 10, the other conductive lead 372 of the two conductive leads 372 of the heating component 37 is pressed to the surface of the base 10 by the core seat 36 to establish an electrical connection with the base 10.

[0064] Specifically, Figure 2 As shown, in the embodiment of the present invention, in this embodiment, the second air hole 352 of the air passage 35 is opened on the groove wall of the atomization groove 361. When the core seat 36 is installed in the installation cavity 11, the air flow can flow into the air passage 35 from the first air hole 351 at the bottom of the core seat 36, and then flow into the atomization groove 361 through the second air hole 352, thereby effectively avoiding the phenomenon of holding the air when the atomization seat is pressed into the installation cavity 11. At the same time, the second air hole 352 is set on the side wall of the atomization groove 361, and is avoided from the bottom wall, thereby effectively preventing the phenomenon of smoke liquid leaking from the second air hole 352.

[0065] Specifically, Figure 3As shown, in the embodiment of the present invention, the base 10 is also provided with an air inlet 14, and the side wall of the core seat 36 is also provided with a third air hole 353 connected to the air channel 35. When the core seat 36 is installed in the installation cavity 11, the third air hole 353 is connected to the air inlet 14 so that the external air flow can flow into the atomization groove 361 through the air inlet 14, the third air hole 353, the air channel 35, and the second air hole 352 to provide working airflow.

[0066] Specifically, Figure 7 As shown, in the embodiment of the present invention, the atomization device 100 further includes a shell 50, and the shell 50 is sleeved on one end of the base 10 provided with a mounting cavity 11, and is surrounded with the base 10 to form an air guide cavity 51 connected with the mounting cavity 11, and the shell 50 is also provided with a suction port 52 to connect the air guide cavity 51 with the external air path. The inner wall of the shell 50 is also provided with a pressing edge 53, and when the shell 50 is sleeved on the base 10, at least part of the pressing edge 53 abuts against the heating core component 30 to press the heating core component 30 into the mounting cavity 11. Here, in this embodiment, the inner wall of the shell 50 is also provided with a pressing edge 53, which further effectively prevents the heating core component 30 from shaking.

[0067] like Figure 8 As shown, in an embodiment of the present invention, in this embodiment, an electronic cigarette 1000 is further provided, including a power supply device 300 and an atomization device 100. The specific structure of the atomization device 100 refers to the above embodiment. Since the electronic cigarette 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
