Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomization unit and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices, also known as electronic cigarettes, are devices that heat and atomize a liquid atomizing medium to generate an aerosol for users to inhale, simulating the feeling of smoking. As a tobacco substitute, they are very popular among smokers. Common electronic atomizing devices typically include an atomizer and a power supply component electrically connected to the atomizer. The atomizer includes an atomizing unit, which, under the electrical drive of the power supply component, heats and atomizes the atomizing medium stored within the atomizer for users to inhale, achieving the effect of simulating smoking.

[0003] For the atomizing unit of an electronic atomizing device, its most crucial component is the atomizing coil, and one of the core components of the atomizing coil is the heating wire. Because the heating wire is in constant contact with the atomizing medium, scale and other deposits can easily form on its surface, necessitating periodic replacement. Currently, the heating wire in most electronic atomizing devices is fixed inside the atomizer, making regular replacement inconvenient. Especially after prolonged use, if the heating wire is not removed and replaced promptly, it not only affects the atomization effect but also poses a health hazard to the user. Conversely, discarding the entire electronic atomizing device not only wastes resources and increases operating costs but also pollutes the environment. Utility Model Content

[0004] Therefore, it is necessary to provide an atomizing unit and an electronic atomizing device including the power supply unit to address the problem that the heating wire of existing electronic atomizing devices is inconvenient to remove and replace, so as to solve the above-mentioned problem.

[0005] According to one aspect of this application, an atomizing unit is provided, which can be detachably used with the main unit of an electronic atomizing device, the atomizing unit comprising:

[0006] The suction nozzle has air outlets extending through its own axial direction at opposite ends;

[0007] The heating element includes an atomizing tube and an atomizing core. One end of the atomizing tube is detachably connected to the mouthpiece, and the atomizing tube has air passages extending through its axial direction to opposite ends, the air passages being connected to the air outlet. The atomizing core is disposed within the air passages, and the atomizing core has a first pin and a second pin, both of which are partially exposed outside the atomizing tube for connection to the power supply component of the host device.

[0008] In one embodiment, the heating component further includes a first conductive sleeve and a second conductive sleeve that are coaxially adjacent to and connected to the atomizing tube along the axial direction of the atomizing tube. The first conductive sleeve abuts against the first pin, and the second conductive sleeve abuts against the second pin. One of the first conductive sleeve and the second conductive sleeve is used to connect to the positive terminal of the power supply component, and the other is used to connect to the negative terminal of the power supply component.

[0009] In one embodiment, the heating component further includes a pin fixing member, which is coaxially connected to the end of the atomizing tube away from the mouthpiece and partially exposed outside the atomizing tube. The first conductive sleeve and the second conductive sleeve are both fitted onto the pin fixing member, and the first pin and the second pin pass through the pin fixing member.

[0010] In one embodiment, the pin fixing member has a first through hole extending through its axially opposite ends, and the wall of the first through hole has a second through hole communicating with the outside of the pin fixing member. The first conductive sleeve covers the second through hole, the first pin passes through the first through hole and the second through hole in sequence, and the second pin passes through the first through hole and is wrapped around the bottom end face of the pin fixing member.

[0011] In one embodiment, the nozzle is detachably threaded to the atomizing tube.

[0012] According to another aspect of this application, an electronic atomizing device is provided, including a main unit, the main unit including a liquid storage component and a power supply component connected to each other, the liquid storage component having a communicating liquid storage chamber and a mounting hole, and the power supply component having a first conductive sheet and a second conductive sheet;

[0013] As described in any of the above embodiments, the atomizing unit can be detachably inserted into the mounting hole, and the atomizing core of the atomizing unit forms an atomizing cavity;

[0014] When the atomizing unit is inserted into the mounting hole and the nozzle of the atomizing unit closes the opening of the mounting hole, the atomizing chamber is connected to the liquid storage chamber, the first pin is connected to the first conductive sheet, and the second pin is connected to the second conductive sheet.

[0015] In one embodiment, the liquid storage chamber is provided with a liquid storage component, which surrounds the mounting hole. When the atomizing unit is inserted into the mounting hole, the liquid storage component covers the atomizing tube of the atomizing unit.

[0016] In one embodiment, the liquid storage assembly includes a housing, a first seal, and a second seal. The housing has openings at opposite ends, and the first seal and the second seal respectively close the openings at both ends of the housing. The liquid storage cavity is formed by the inner wall of the housing, the first seal, and the second seal together.

[0017] In one embodiment, the liquid storage assembly further includes a sleeve disposed within the liquid storage cavity. One end of the sleeve is connected to the first sealing element, and the other end is connected to the second sealing element. The sleeve forms a first cavity, and the outer wall of the sleeve and the inner wall of the housing form a second cavity, such that the liquid storage cavity is divided into the first cavity and the second cavity by the sleeve. The sleeve has a liquid passage hole that connects the first cavity and the second cavity. The liquid storage component is disposed within the sleeve and fills the first cavity.

[0018] In one embodiment, the housing has an injection hole that communicates with the liquid storage chamber, and an injection plug is detachably provided at the position of the injection hole so that the injection plug can open or close the injection hole.

[0019] The aforementioned electronic atomizing device, by detachably connecting the mouthpiece to the atomizing tube of the heating element and placing the atomizing core inside the atomizing tube, with the first and second leads of the atomizing core partially exposed outside the atomizing tube for connection with the main unit of the electronic atomizing device, forms an atomizing unit that can be detachably used with the main unit of the electronic atomizing device. In practical use, the atomizing unit can be detachably inserted into the mounting hole of the main unit. When the atomizing unit is inserted into the mounting hole, the liquid storage chamber of the main unit can communicate with the atomizing chamber to form a complete electronic atomizing device. When the heating element needs to be replaced after prolonged use, simply pull out the mouthpiece to remove the entire atomizing unit, replace it with a new heating element, reassemble it with the mouthpiece to form a new atomizing unit, and then insert it back into the mounting hole of the main unit for continued use of the electronic atomizing device. This not only facilitates the replacement of the heating element but also enables the reusability of the electronic atomizing device, improving its reusability and avoiding resource waste.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] One embodiment of this application provides an atomizing unit and an electronic atomizing device, wherein the electronic atomizing device includes an atomizing unit. The electronic atomizing device is used to heat the atomizing medium stored inside the atomizing unit to form an aerosol for inhalation by a user.

[0035] The following description uses an electronic cigarette as an example of an electronic atomizing device and e-liquid as an atomizing medium to illustrate the structure of the electronic atomizing device in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomizing device of this application is not limited to an electronic cigarette, but can also be any other electronic atomizing device capable of atomizing a medium into an aerosol, which is not limited here.

[0036] See Figures 1 to 4 , Figure 1 This paper shows a schematic diagram of the appearance of the electronic atomizing device 10 in one embodiment of the present application. Figure 2 An explosion diagram of the electronic atomizing device 10 is shown. Figure 3 An exploded cross-sectional view of the internal structure of the electronic atomizing device 10 is shown. Figure 4 A cross-sectional view of the internal structure of the electronic atomizing device 10 is shown. An embodiment of this application provides an electronic atomizing device 10 including a main unit 100 and an atomizing unit 200 detachably connected to each other. The main unit 100 has an air inlet 101, and the atomizing unit 200 has an air outlet 201. The main unit 100 stores an atomizing medium and provides electrical energy to the atomizing unit 200, so that when the atomizing unit 200 is connected to the main unit 100, the atomizing unit 200, driven by the electrical energy provided by the main unit 100, heats and atomizes the atomizing medium stored in the main unit 100 to generate an aerosol for the user to inhale.

[0037] Specifically, combined with Figure 5As shown in the embodiments of this application, the host 100 includes a liquid storage component 110 and a power supply component 120 connected to each other. The liquid storage component 110 has a liquid storage chamber 102 and a mounting hole 103 that are connected to each other. The power supply component 120 has a first conductive plate 121 and a second conductive plate 122 that represent the positive and negative electrodes, respectively. The liquid storage chamber 102 is used to store the atomizing medium. The atomizing unit 200 can be detachably inserted into the mounting hole 103. The atomizing unit 200 has an atomizing core 222. The atomizing core 222 forms an atomizing chamber 202 that connects the air inlet 101 and the air outlet 201, and has a first pin 2221 and a second pin 2222. When the atomizing unit 200 is inserted into the mounting hole 103 and the opening of the mounting hole 103 is closed, the first pin 2221 is connected to the first conductive plate 121, and the second pin 2222 is connected to the second conductive plate 122, so that the atomizing unit 200 and the host 100 can be electrically connected. When the user inhales, outside air enters the atomizing chamber 202 through the air inlet 101. Driven by electrical energy, the atomizing core 222 generates heat, which heats and atomizes the atomizing medium entering the atomizing core 222 from the liquid storage chamber 102. After generating an aerosol in the atomizing chamber 202, it mixes with the outside air and is discharged from the air outlet 201 and inhaled by the user.

[0038] More specifically, in some embodiments, the liquid storage assembly 110 includes a housing 111, a first seal 112, and a second seal 113. The housing 111 has openings at opposite ends, and the first seal 112 and the second seal 113 respectively close the openings at opposite ends of the housing 111. The power supply assembly 120 is connected to the second seal 113. The liquid storage chamber 102 is formed by the inner wall of the housing 111, the first seal 112, and the second seal 113. In one embodiment, the liquid storage chamber 102 is provided with a liquid storage element 114 made of fiber cotton. The liquid storage element 114 forms a mounting hole 103. When the atomizing unit 200 is inserted into the mounting hole 103, the liquid storage element 114 covers the portion of the atomizing unit 200 inserted into the mounting hole 103. The advantage of this design is that the liquid storage component 114 has the function of locking and guiding liquid. Therefore, the atomizing medium in the liquid storage chamber 102 can be immersed in the liquid storage component 114, thereby preventing the atomizing medium from flowing arbitrarily and avoiding leakage of the atomizing medium from the liquid storage chamber 102. While making it convenient for the main unit 100 to form the mounting hole 103 for the atomizing unit 200 to be inserted, it can also ensure that the electronic atomizing device 10 has enough atomizing medium supplied to the atomizing unit 200 during use, avoiding the phenomenon of dry burning and scorching of the core.

[0039] Based on the above embodiments, preferably, as follows: Figure 4As shown, the liquid storage assembly 110 also includes a sleeve 115 disposed within the liquid storage chamber 102. One end of the sleeve 115 along its own axial direction is connected to a first sealing element 112, and the other end is connected to a second sealing element 113. As can be seen from the figure, the sleeve 115 forms a first cavity 1021, and the outer wall of the sleeve 115 and the inner wall of the housing 111 form a second cavity 1022, so that the liquid storage chamber 102 is divided into the first cavity 1021 and the second cavity 1022 by the sleeve 115. The sleeve 115 has a liquid passage hole (not shown in the figure) connecting the first cavity 1021 and the second cavity 1022. The oil storage element is disposed within the sleeve 115 and fills the first cavity 1021.

[0040] Through the above design, a portion of the atomizing medium in the liquid storage chamber 102 can be locked in the liquid storage component 114, while the other portion is stored in the second chamber 1022 in liquid form. After a portion of the atomizing medium immersed in the liquid storage component 114 in the first chamber 1021 is consumed, the atomizing medium in the second chamber 1022 can be replenished to the first chamber 1021 in a timely manner through the liquid passage. This not only leverages the advantages of the liquid storage component 114 in locking and guiding liquid, but also allows the liquid storage chamber 102 to directly store the liquid atomizing medium, thereby improving the utilization rate of the atomizing medium and enhancing the suction experience.

[0041] Furthermore, in an optional embodiment, such as Figure 4 and Figure 5 As shown, the housing 111 also has an injection hole 104 communicating with the liquid storage chamber 102. An injection plug 116 is detachably provided at the injection hole 104 so that the injection plug 116 can open or close the injection hole 104. When the injection plug 116 opens the injection hole 104, after the atomizing medium in the liquid storage chamber 102 is used up, new atomizing medium can be injected through the injection hole 104; after the injection is completed, the injection plug 116 closes the injection hole 104 to maintain the sealed state of the atomizing medium in the liquid storage chamber 102.

[0042] Regarding the structure of the power supply component 120, the power supply component 120 includes a battery, a circuit board and an airflow sensor. The air inlet 101 is opened on the housing of the power supply component 120. The specific structure of the power supply component 120 can be referred to the prior art, and will not be described in detail here.

[0043] See Figures 2 to 4In the embodiment shown in the figure, the atomizing unit 200 includes a mouthpiece 210 and a heating element 220. The mouthpiece 210 has an air outlet 201 extending through its two opposite ends along its axial direction. The heating element 220 includes an atomizing tube 221 and an atomizing core 222. One end of the atomizing tube 221 is detachably coaxially connected to the mouthpiece 210 by means of threaded connection or magnetic connection. The atomizing tube 221 has an air passage 2211 extending through its two opposite ends along its axial direction and communicating with the air outlet 201. The atomizing core 222 is disposed in the air passage 2211. The tube wall of the atomizing tube 221 also has a liquid inlet 2212 communicating with the air passage 2211. The atomizing core 222 includes a liquid guiding component made of ceramic or fiber cotton and a heating element connected to the liquid guiding component. The liquid guiding component covers the liquid inlet hole 2212 and forms an atomizing chamber 202. The first pin 2221 and the second pin 2222 are led out from the heating element and are partially exposed in the atomizing tube 221 for connection with the power supply component 120 of the main unit 100.

[0044] In the connection structure between the first pin 2221 and the first conductive sheet 121, and in the connection structure between the second pin 2222 and the second conductive sheet 122, it is understood that the first pin 2221 and the first conductive sheet 121, and the second pin 2222 and the second conductive sheet 122, can be directly connected. However, because the first pin 2221 and the second pin 2222 are relatively thin, and the contact area between the first conductive sheet 121 and the second conductive sheet 122 is also limited, it cannot be guaranteed that the first pin 2221 and the first conductive sheet 121, and the second pin 2222 and the second conductive sheet 122, will make contact, which may lead to poor contact.

[0045] To address this issue, in a preferred embodiment, such as Figure 5 and Figure 6 As shown, the heating element 220 also includes a first conductive sleeve 223 and a second conductive sleeve 224, which are coaxially adjacent to and connected to the atomizing tube 221 along its axial direction. The first conductive sleeve 223 and the second conductive sleeve 224 can be made of conductive materials, such as copper or other conductive metals. The first conductive sleeve 223 abuts against the first pin 2221, and the second conductive sleeve 224 abuts against the second pin 2222, allowing the first conductive sheet 121 to be connected to the first pin 2221 via the first conductive sleeve 223, and the second conductive sheet 122 to be connected to the second pin 2222 via the second conductive sleeve 224. It can be seen that since both the first conductive sleeve 223 and the second conductive sleeve 224 have cylindrical structures with large outer circumferential areas, the first conductive sleeve 223 has a larger contact area with the first conductive sheet 121, and the second conductive sleeve 224 has a larger contact area with the second conductive sheet 122, thus solving the aforementioned problem of poor contact.

[0046] Furthermore, in order to facilitate the fixing of the first conductive sleeve 223 and the second conductive sleeve 224, and in order to facilitate the fixing of the first pin 2221 and the second pin 2222, the heating component 220 also includes a pin fixing member 225. The pin fixing member 225 is coaxially connected to the end of the atomizing tube 221 away from the nozzle 210 and is partially exposed outside the atomizing tube 221. The first conductive sleeve 223 and the second conductive sleeve 224 are both sleeved on the pin fixing member 225, and the first pin 2221 and the second pin 2222 both pass through the pin fixing member 225.

[0047] More specifically, such as Figure 6 As shown, the pin fixing member 225 has a first through hole 2251 that passes through its two opposite ends along its axial direction. The wall of the first through hole 2251 has a second through hole 2252 that connects to the outside of the pin fixing member 225. The first conductive sleeve 223 covers the second through hole 2252. The first pin 2221 and the second pin 2222 are both bent and extended. Specifically, the first pin 2221 is inserted into the first through hole 2251 and bent at the junction of the first through hole 2251 and the second through hole 2252 before being inserted into the second through hole 2252. The portion of the first pin 2221 exposed in the second through hole 2252 abuts against the inner wall of the first conductive sleeve 223. The second pin 2222 passes through the second through hole 2252, and the portion of it exposed in the second through hole 2252 is wrapped around the bottom end face of the pin fixing member 225 and abuts against the inner wall of the second conductive sleeve 224. This allows the first pin 2221 and the second pin 2222 to be firmly fixed and to be tightly connected to the first conductive sleeve 223 and the second conductive sleeve 224, respectively.

[0048] Thus, when the atomizing unit 200 is inserted into the mounting hole 103 of the main unit 100, the atomizing tube 221 is accommodated in the mounting position and wrapped by the liquid storage component 114. The atomizing chamber 202 is connected to the liquid storage chamber 102 through the liquid inlet. The atomizing medium in the liquid storage chamber 102 can enter the atomizing core 222 through the liquid inlet and be heated and atomized by the heating element of the atomizing core 222. It can be seen that through the above structural design, the atomizing unit 200 can be easily installed into the mounting hole 103 of the main unit 100 and easily removed from the main unit 100, so that the heating component 220 can be a disposable consumable. When the heating element 220 needs to be replaced after prolonged use, simply pull out the mouthpiece 210 to remove the entire atomizing unit 200. Then replace the heating element 220 with a new one, reassemble it with the mouthpiece 210 to form a new atomizing unit 200, and insert it into the mounting hole 103 of the main unit 100. Connect the first conductive sleeve 223 to the first conductive plate 121 and the second conductive sleeve 224 to the second conductive plate 122 to ensure circuit continuity. Let it sit for five to ten minutes, then blow three to five puffs into the mouthpiece 210 to ensure that the atomizing medium can flow from the liquid storage chamber 102 to the atomizing core 222. You can then continue to use the electronic atomizing device 10.

[0049] Therefore, the electronic atomizing device 10 provided in this application makes it very convenient to replace the heating component 220, and also enables the electronic atomizing device 10 to be reused. While improving the reusability of the electronic atomizing device 10, it avoids the waste of resources and is conducive to promoting green environmental protection.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
