Description

Technical Field

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

[0002] Electronic atomizing devices, also known as electronic cigarettes, are devices that heat and atomize a medium to generate an aerosol for users to inhale, simulating the sensation of smoking. Internally, electronic atomizing devices contain an e-liquid reservoir and an atomizing assembly. The e-liquid is stored in the reservoir, and the atomizing assembly contains an atomizing chamber, which, when powered on, heats and atomizes the e-liquid in the reservoir, generating an aerosol for the user to inhale.

[0003] To increase the vaping capacity of e-cigarettes, some large-capacity pre-filled e-cigarettes and open-fill (user-filled) e-cigarettes have appeared on the market. While these types of e-cigarettes have the advantage of large e-liquid capacity, the volume of the e-liquid reservoir is much larger than that of the atomizing chamber. When the external air pressure or temperature changes, the internal pressure of the e-liquid reservoir may be higher than the external air pressure. This causes the e-liquid to flow faster, resulting in a greater impact force on the atomizing components. Consequently, e-liquid is more likely to leak from the atomizing chamber to the outside of the e-cigarette, affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide an atomizer and an electronic atomizing device that can solve the above problems, which are caused by the fast flow rate of e-liquid in existing electronic atomizing devices, resulting in a large impact force of e-liquid on the atomizing components, and thus causing e-liquid to easily leak from the atomizing chamber to the outside of the electronic atomizing device under the action of air pressure difference.

[0005] According to one aspect of this application, an atomizer is provided, comprising:

[0006] case;

[0007] An oil storage assembly is disposed inside the housing and forms a first oil storage cavity with the inner wall of the housing. The oil storage assembly has an oil guiding cavity and a second oil storage cavity. One end of the oil guiding cavity is connected to the first oil storage cavity and the other end is connected to the second oil storage cavity.

[0008] An atomizing component is disposed within the oil storage component. The atomizing component has an atomizing core, one side of which faces the second oil storage chamber, and the other side forms an atomizing chamber that communicates with the external environment.

[0009] In one embodiment, the volume of the oil guide cavity and the volume of the second oil storage cavity are both smaller than the volume of the first oil storage cavity.

[0010] In one embodiment, the top wall of the oil storage assembly has an oil passage hole, one end of which is connected to the first oil storage cavity and the other end is connected to the oil guiding cavity.

[0011] In one embodiment, the oil storage assembly has a vent, one end of which is connected to the first oil storage chamber and the other end is connected to the second oil storage chamber.

[0012] In one embodiment, the oil storage assembly has a boss extending toward the second oil storage chamber, and the oil guide chamber and the vent are formed on the boss.

[0013] In one embodiment, the second oil storage cavity is provided with oil storage cotton, which wraps the atomizing component. The oil storage cotton has a first oil guiding surface and a second oil guiding surface. The first oil guiding surface is disposed facing the opening of the oil guiding cavity, and the second oil guiding surface is disposed facing the side wall of the atomizing core. The central axis of the atomizing core is parallel to the central axis of the oil guiding cavity.

[0014] In one embodiment, the end of the boss away from the first oil storage cavity has an annular rib protruding from the boss, the annular rib surrounds the opening of the oil guide cavity and the vent hole, and the annular rib forms a venting groove that connects the oil guide cavity and the vent hole, and the oil storage cotton is attached to the annular rib and closes the venting groove.

[0015] In one embodiment, the oil guiding cavity is provided with an oil guiding rod, one end of which is connected to the first oil guiding surface.

[0016] In one embodiment, a baffle is provided in the second oil storage cavity, the baffle dividing the second oil storage cavity into a first cavity and a second cavity. One side of the baffle is spaced apart from the cavity wall of the second oil storage cavity to form an oil passage gap that connects the first cavity and the second cavity. The top edge of the baffle is connected to the boss, and at least one other side of the baffle is connected to the cavity wall of the second oil storage cavity.

[0017] According to another aspect of this application, an electronic atomizing device is provided, comprising:

[0018] Atomizers as described in any of the above solutions;

[0019] A bottom cover is connected to the atomizer. The bottom cover and the housing of the atomizer form a receiving cavity. A first power supply component electrically connected to the atomizing core is provided in the receiving cavity, and / or a second power supply component electrically connected to the atomizing core is provided outside the bottom cover and the housing.

[0020] The aforementioned atomizer and electronic atomizing device include an oil storage component within the atomizer's housing assembly. The inner wall of the oil storage component's housing forms a first oil storage chamber. The oil storage component itself contains a guide chamber and a second oil storage chamber. One end of the guide chamber connects to the first oil storage chamber, and the other end connects to the second oil storage chamber. This allows a portion of the atomized liquid in the first oil storage chamber to first flow into the guide chamber and then into the second oil storage chamber, thus gradually slowing the flow rate of the atomized liquid. When external air pressure or temperature changes, the atomizing component only needs to withstand a small amount of liquid pressure. This prevents the atomized liquid from leaking from the atomizing chamber to the outside of the atomizer, effectively reducing the risk of leakage and solving the leakage problem that easily occurs in existing pre-filled electronic atomizing devices or open-fill electronic atomizing devices due to pressure imbalance inside and outside the oil storage chamber.

[0040] One embodiment of this application provides an electronic atomizing device for heating an atomizing liquid stored inside the device to form an aerosol for inhalation by a user.

[0041] The following description uses an electronic cigarette as an example of an electronic atomizing device and e-liquid as an example of an e-liquid 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 e-liquid into an aerosol, which is not limited here.

[0042] See Figures 1 to 4 , Figure 1 and Figure 2 This paper shows a schematic diagram of the appearance of the electronic atomizing device 10 in one embodiment of the present application. Figure 3 An explosion diagram 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 the electronic atomizing device 10 provided in this application includes an atomizer 100 and a power supply unit 200. The power supply unit 200 and the atomizer 100 are interconnected. The atomizer 100 has a first air inlet 101 and an air outlet 102 that are interconnected. The power supply unit 200 has a second air inlet 103 that is connected to the first air inlet 101. The power supply unit 200 supplies power to the atomizer 100, which, under the influence of the electrical energy provided by the power supply unit 200, heats the atomizing liquid (e.g., e-liquid, hereinafter referred to as e-liquid) stored within itself, so that the e-liquid can be atomized to generate an aerosol. When the user inhales, outside air enters the power supply unit 200 through the second air inlet 103, then enters the atomizer 100 through the first air inlet 101, mixes with the aerosol, and is inhaled by the user through the air outlet 102.

[0043] See Figure 3 and Figure 4 In the embodiment shown in the figure, the atomizer 100 includes a housing 110, an oil storage assembly 120, and an atomizing assembly 130. A first air inlet 101 and an air outlet 102 are opened at opposite ends of the housing 110. The oil storage assembly 120 is disposed inside the housing 110 and together with the inner wall of the housing 110, forms a first oil storage chamber 104 for storing e-liquid. The oil storage assembly 120 itself has an oil guiding chamber 105 and a second oil storage chamber 106. One end of the oil guiding chamber 105 is connected to the first oil storage chamber 104, and the other end is connected to the second oil storage chamber 106, so that the first oil storage chamber 104 is connected to the second oil storage chamber 106 through the oil guiding chamber 105. The atomizing assembly 130 is disposed inside the oil storage assembly 120 and has an atomizing chamber 132a that connects the first air inlet 101 and the air outlet 102.

[0044] Specifically, in combination Figure 4 and Figure 5As shown, the housing 110 has a connecting post 111 extending toward the inner cavity of the housing 110, and the oil storage assembly 120 is connected to the connecting post 111 to be fixed in the housing 110; the atomizing assembly 130 includes an atomizing tube 131 and an atomizing core 132. The atomizing tube 131 forms an air passage 131b that connects the first air inlet 101 and the air outlet 102 and has an oil inlet hole 131a that connects to the air passage 131b. The atomizing core 132 is disposed in the air passage 131b. More specifically, the atomizing core 132 includes an oil guide and a heating element connected to the oil guide. In one embodiment, the oil guide is cylindrical, with its outer circumferential surface attached to the wall of the atomizing tube 131 and covering the inner opening of the oil inlet 131a. The atomizing chamber 132a is enclosed by the oil guide, and the heating element is attached to the inner wall of the oil guide (i.e., the chamber wall of the atomizing chamber 132a). The atomizing chamber 132a is connected to the first air inlet 101 and the air outlet 102 through the atomizing tube 131. The oil guide can be made of fiber cotton or ceramic, and it has the functions of breathability, oil locking, and oil guiding. When the electronic atomizing device 10 is working and the user is inhaling, some of the e-liquid in the first oil storage chamber 104 can enter the second oil storage chamber 106 through the oil guide chamber 105, and then enter the oil guide component of the atomizing core 132 from the second oil storage chamber 106, so that it can be heated by the heating element and form an aerosol in the atomizing chamber 132a. The aerosol flows out from the air outlet 102 through the air passage 131b for the user to inhale.

[0045] It should be noted that the inner side of the oil inlet 131a is relative to the atomizing tube 131. The inside of the atomizing tube 131 is defined as the inner side, and the outside of the atomizing tube 131 is defined as the outer side. It is understood that the structure of the atomizing coil 132 is not limited to the above structure, and can also be other structures. For details, please refer to the existing technology, which will not be elaborated here.

[0046] As can be seen, by setting the oil storage component 120, the inner cavity of the housing 110 is divided into three cavities: a first oil storage cavity 104, an oil guiding cavity 105, and a second oil storage cavity 106. Preferably, the volume of the oil guiding cavity 105 and the volume of the second oil storage cavity 106 are both smaller than those of the first oil storage cavity 104. More preferably, the volume of the oil guiding cavity 105 is smaller than that of the second oil storage cavity 106. This allows a portion of the e-liquid in the first oil storage cavity 104 to first flow into the oil guiding cavity 105, and then into the second oil storage cavity 106, which has a smaller volume than the first oil storage cavity 104. This gradually slows down the flow rate of the e-liquid. In particular, when the electronic atomizing device 10 is subjected to vibration during transportation, the oil guiding cavity 105 provides a buffer space, preventing the e-liquid in the first oil storage cavity 104 from being continuously and directly squeezed into the atomizing core 132. Thus, when the external air pressure or temperature changes, the atomizing component 130 only needs to withstand a small liquid pressure, and the e-liquid is less likely to leak from the atomizing chamber 132a to the outside of the atomizer 100, thereby effectively reducing the risk of leakage.

[0047] In some preferred embodiments, such as Figure 5 and Figure 6 As shown, the top wall of the e-liquid storage assembly 120 has an oil passage hole 107. One end of the oil passage hole 107 connects to the first e-liquid storage chamber 104, and the other end connects to the e-liquid guiding chamber 105. As can be seen from the figure, the diameter of the oil passage hole 107 is relatively small. By opening the oil passage hole 107, the flow rate of the e-liquid can be further slowed down, thereby further reducing the liquid pressure borne by the atomizing core 132. Figure 6 In the embodiment, there are two oil passage holes 107. It is understood that the number of oil passage holes 107 is not limited, and the shape of the oil passage holes 107 is also not limited. The impact force of the e-liquid on the atomizing core 132 can be adjusted by changing the number and shape of the oil passage holes 107.

[0048] See Figure 5 , Figure 6 and Figure 7 Regarding the specific structure of the oil storage assembly 120, the oil storage assembly 120 includes a seal 121 and a bracket 122 connected to each other. In the figure, the seal 121 is connected to the upper side of the bracket 122. The outer wall of the seal 121 and the inner wall of the housing 110 form a first oil storage cavity 104. The bracket 122 is connected to the lower side of the seal 121. A first air inlet 101 is opened on the bracket 122. An oil guide cavity 105 is opened inside the seal 121. The inner wall of the seal 121 and the inner wall of the bracket 122 together form a second oil storage cavity 106.

[0049] As a preferred embodiment, see [reference]. Figure 5 , Figure 7 and Figure 8 The seal 121 has a boss 1211 extending toward the second oil reservoir 106. An oil guide cavity 105 is formed on the boss 1211 and extends through the end of the boss 1211 near the second oil reservoir 106. An oil passage hole 107 is formed on the top wall of the bracket 122 and extends toward the boss 1211 to communicate with the oil guide cavity 105. More preferably, see [reference needed]. Figure 9 The second oil storage chamber 106 is also provided with a baffle 1221, which divides the second oil storage chamber 106 into a first chamber 106a and a second chamber 106b. One side of the baffle 1221 is spaced apart from the cavity wall of the second oil storage chamber 106 to form an oil passage gap 122a that connects the first chamber 106a and the second chamber 106b. As shown in the figure, the top edge of the baffle 1221 is connected to the boss 1211, and the other sides of the baffle 1221 are connected to the cavity wall of the second oil storage chamber 106.

[0050] Further, see Figure 5 and Figure 7The second oil storage chamber 106 is provided with an oil storage cotton 124 made of fiber cotton with oil storage, oil guiding and oil locking functions. The oil storage cotton 124 wraps the atomizing component 130 and has a first oil guiding surface 1241 and a second oil guiding surface 1242. The first oil guiding surface 1241 faces the opening of the oil guiding chamber 105, and the second oil guiding surface 1242 faces the side wall of the atomizing core 132. The central axis of the atomizing core 132 is parallel to the central axis of the oil guiding chamber 105. Furthermore, the oil guiding component also includes an oil guiding rod 123 made of fiber cotton. The oil guiding rod 123 fills the oil guiding chamber 105 and is connected to the first oil guiding surface 1241.

[0051] Thus, it can be seen that through the above series of settings, under the joint guidance of the oil guide rod 123 and the oil storage cotton 124, the e-liquid can only flow into the atomizing core 132 along a tortuous path, thereby further reducing the flow speed of the e-liquid and relieving the pressure of the e-liquid.

[0052] It should be noted that during the use of the electronic atomizing device 10, the e-liquid in the first reservoir 104 gradually decreases. As the e-liquid in the first reservoir 104 enters the second reservoir 106, it compresses the air in the second reservoir 106. After being compressed to a certain extent, the air in the second reservoir 106 accumulates, causing an imbalance between the air pressure in the first reservoir 104 and the air pressure in the second reservoir 106. This, in turn, hinders the e-liquid in the first reservoir 104 from entering the second reservoir 106. The final result is that the e-liquid in the first reservoir 104 cannot smoothly enter the second reservoir 106.

[0053] Therefore, in order to solve this problem, such as Figure 9 As shown, the sealing element 121 of the oil storage assembly 120 is also provided with a vent 108. One end of the vent 108 is connected to the first oil storage chamber 104, and the other end is connected to the second oil storage chamber 106. By providing the vent 108, the gas in the second oil storage chamber 106, after being compressed by the gradually increasing e-liquid, can be discharged into the first oil storage chamber 104 through the vent 108, thereby maintaining the air pressure balance between the first oil storage chamber 104 and the second oil storage chamber 106 and avoiding the phenomenon of poor oil intake. In the embodiment shown in the figure, the number of vent 108 is twice that of the oil passage holes 107, that is, each oil passage hole 107 has a vent 108 on both sides, and the vent 108 extends into the boss 1211 of the sealing element 121 and connects to the oil guide chamber 105. Of course, the number of vent 108 can be arbitrary and is not limited to the number shown in the embodiment shown in the figure.

[0054] It is also worth noting that when the second oil storage chamber 106 and the first oil storage chamber 104 are exchanging air, if there is a lot of gas in the second oil storage chamber 106, the gas will concentrate and rush to the ventilation hole 108, and continuously enter the first oil storage chamber 104 through the ventilation hole 108 for air exchange. As a result, the e-liquid in the first oil storage chamber 104 is continuously introduced into the oil guiding chamber 105 at a relatively fast speed, which in turn causes the oil guiding rod 123 to continuously guide oil into the second oil storage chamber 106. When the e-liquid entering the second oil storage chamber 106 exceeds the oil-locking capacity of the oil-retaining cotton 124, the e-liquid will continuously seep out from the oil-retaining cotton 124. When too much e-liquid seeps out, the e-liquid will seep out from the oil inlet hole 131a, resulting in oil leakage.

[0055] Therefore, in order to solve this problem as well, based on the above embodiments, as a further improvement, such as... Figure 8 and Figure 10 As shown, the boss 1211 has an annular rib 1212 protruding from the boss 1211 at one end away from the first oil storage cavity 104. The annular rib 1212 surrounds the opening of the oil guide cavity 105 and the vent hole 108, and the annular rib 1212 forms a venting groove 109 that connects the oil guide cavity 105 and the vent hole 108. The oil storage cotton 124 is attached to the annular rib 1212 and closes the venting groove 109.

[0056] Thus, it is easy to see that by setting the annular rib 1212 to form the ventilation groove 109, and by attaching the oil-collecting cotton 124 to the annular rib 1212 to seal the ventilation groove 109, only the gas in the ventilation groove 109 can enter the first oil-collecting chamber 104 through the ventilation hole 108. Therefore, the e-liquid in the first oil-collecting chamber 104 can be introduced into the oil-guiding chamber 105 at a slower speed and then into the second oil-collecting chamber 106. This can prevent the gas in the second oil-collecting chamber 106 from being continuously ventilated, thus preventing the oil guide rod 123 from continuously guiding oil and thus preventing oil leakage due to excessive oil seepage.

[0057] Additionally, see Figure 11 The bottom wall surface of the support 122, which forms the second oil storage chamber 106, is also provided with multiple spaced oil guide strips 1222. All the oil guide strips 1222 form multiple spaced oil collection grooves 122b. The purpose of forming multiple oil collection grooves 122b is to ensure that if excessive oil seepage occurs, the seeping e-liquid can be collected and temporarily stored in the oil collection grooves 122b and will not flow randomly, thereby slowing down the seepage of e-liquid at a relatively fast speed to a certain extent.

[0058] Please continue reading. Figure 2 and Figure 3In terms of the structure of the power supply unit 200, the power supply unit 200 includes a bottom cover 210, a first power supply component 220, and a second power supply component 230. The bottom cover 210 is connected to the housing 110 of the atomizer 100 and forms a receiving cavity 201 with the housing 110. A second air inlet 103 is opened on the bottom cover 210. The first power supply component 220 is disposed in the receiving cavity 201 and electrically connected to the heating element of the atomizing core 132. The second power supply component 230 is disposed outside the bottom cover 210 and the housing 110 and is also electrically connected to the heating element of the atomizing core 132. Preferably, the second oil storage component 120 is detachably connected to the housing 110 and the bottom cover 210 by means of magnetic attraction or snap-fit ​​connection.

[0059] Thus, both the first power supply component 220 and the second power supply component 230 can supply power to the atomizing coil 132. Even if the second power supply component 230 is separated from the atomizer 100, the first power supply component 220 can still supply power to the atomizing coil 132. Alternatively, when the first power supply component 220 is depleted, connecting the second power supply component 230 to the atomizer 100 can also supply power to the atomizing coil 132, greatly facilitating user operation. Of course, only the first power supply component 220 or only the second power supply component 230 can be provided; this is not limited here. The first power supply component 220 and the second power supply component 230 each include a battery, a circuit board, etc. Specific structures can be found in existing technologies and will not be described in detail here.

[0060] In addition, considering that the aerosol in the atomizing chamber 132a will turn into condensate after cooling, in order to prevent the condensate from dripping down along the atomizing tube 131 and leaking out from the first air inlet 101, such as Figure 2 As shown, the bottom cover 210 is also provided with a partition 211, which divides the receiving cavity 201 into an oil suction cavity 201a and an installation cavity 201b that are isolated from each other. The first power supply component 220 is disposed in the installation cavity 201b. The oil suction cavity 201a is provided with oil-absorbing cotton 240. The first air inlet 101 is connected to the second air inlet 103 through the oil suction cavity 201a. This can ensure that the condensate drips onto the oil-absorbing cotton 240 and is absorbed by the oil-absorbing cotton 240 after dripping downwards, and can also prevent the condensate from dripping onto the first power supply component 220 and causing a short circuit.

[0061] In summary, the electronic atomizing device 10 provided in this application reduces the risk of leakage by gradually decreasing the pressure impact of e-liquid on the atomizing core 132 within the oil storage chamber and by setting an annular rib 1212 to form an air exchange groove 109. Furthermore, by opening an air exchange hole 108, it ensures that e-liquid is smoothly introduced into the atomizing core 132. Under the premise of simple structure and low manufacturing cost, it solves the problem of oil leakage that easily occurs in existing pre-filled electronic atomizing devices 10 or open non-filled electronic atomizing devices 10 due to the pressure imbalance inside and outside the oil storage chamber.
