Atomizer and electronic atomization device

Abstract

This application relates to an atomizer and an electronic atomizing device. The electronic atomizing device includes an atomizer, which comprises a housing assembly, an atomizing component, and an e-liquid storage assembly. The e-liquid storage assembly is disposed within the housing assembly, and its top wall and the inner wall of the housing assembly form a first e-liquid storage chamber. The e-liquid storage assembly also surrounds a second e-liquid storage chamber. The housing assembly is attached to the inner wall of the e-liquid storage assembly and / or the side wall of the e-liquid storage assembly and has a liquid flow channel extending along the side wall of the e-liquid storage assembly. The first e-liquid storage chamber is connected to the second e-liquid storage chamber through the liquid flow channel. The atomizing component is disposed within the e-liquid storage assembly, so that a portion of the e-liquid in the first e-liquid storage chamber flows through the liquid flow channel to the smaller second e-liquid storage chamber, and the e-liquid flow rate is slowed down. Therefore, when the external air pressure or temperature changes, the atomizing core only needs to withstand a small liquid pressure, and the e-liquid is less likely to leak from the atomizing chamber to the outside of the electronic atomizing device under the action of air pressure difference, thereby reducing the risk of e-liquid leakage.

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 feeling of smoking. As an alternative to cigarettes, they are very popular among smokers. Internally, electronic atomizing devices contain an e-liquid reservoir and an atomizing component. The e-liquid is stored in the reservoir, and the atomizing component 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] The housing assembly has a first air inlet and an air outlet;

[0007] An oil storage assembly is disposed within the housing assembly. The sidewall of the oil storage assembly is attached to the inner wall of the housing assembly. The top wall of the oil storage assembly and the inner wall of the housing assembly form a first oil storage cavity. The oil storage assembly also surrounds a second oil storage cavity. A liquid flow channel is provided on the inner wall of the housing assembly where it is attached to the oil storage assembly and / or on the sidewall of the oil storage assembly. The liquid flow channel extends along the sidewall of the oil storage assembly, and the first oil storage cavity is connected to the second oil storage cavity through the liquid flow channel.

[0008] An atomizing component is disposed within the oil storage component and has an atomizing chamber. The atomizing chamber is connected to the second oil storage chamber and to the first air inlet and the air outlet.

[0009] In one embodiment, the top wall of the oil storage assembly has an oil passage groove that connects to the liquid flow channel; the side wall of the oil storage assembly has an oil passage hole, and the second oil storage chamber connects to the liquid flow channel through the oil passage hole.

[0010] In one embodiment, the fluid flow channel extends spirally along the sidewall of the oil storage assembly.

[0011] In one embodiment, the oil storage assembly includes a bracket and a seal, one end of the bracket is open, the seal is connected to the bracket and closes the opening, the second oil storage chamber is formed by the inner wall of the bracket and one side of the seal, and the liquid flow channel is opened on the side wall of the bracket.

[0012] In one embodiment, the second oil storage chamber is provided with oil storage cotton, and the sealing element includes a body and a protrusion on one side of the body. Part of the bottom surface of the oil storage cotton is attached to the protrusion, and another part of the bottom surface is suspended, so that the bottom surface of the oil storage cotton that is suspended, one side surface of the body and the side surface of the protrusion form an oil guide groove in the second oil storage chamber that communicates with the liquid flow channel.

[0013] In one embodiment, an oil-absorbing chamber is formed between the side of the seal opposite to the second oil storage chamber and the bottom wall of the housing assembly, which connects the first air inlet and the atomizing chamber, and the oil-absorbing chamber is filled with an oil-absorbing element.

[0014] In one embodiment, the atomizing assembly includes an atomizing tube and an atomizing core. The atomizing tube forms an air passage connecting the first air inlet and the air outlet. The atomizing core is disposed within the air passage and forms the atomizing cavity. The opposite ends of the atomizing tube are respectively connected to the oil storage assembly, and the atomizing tube has an oil inlet hole at a position corresponding to the atomizing core, connecting the second oil storage cavity and the atomizing core.

[0015] In one embodiment, the atomizing tube has a pressure relief hole near the air outlet, and the second oil storage chamber is connected to the air passage through the pressure relief hole.

[0016] In one embodiment, the second oil storage chamber is provided with oil storage cotton, and the top side of the oil storage cotton is spaced apart from the top wall of the second oil storage chamber, so that the top side of the oil storage cotton and the top wall of the second oil storage chamber form a buffer groove in the second oil storage chamber, and the buffer groove is connected to the air passage through the pressure relief hole.

[0017] According to another aspect of this application, an electronic atomizing device is provided, including a power supply unit and an atomizer as described in any of the above embodiments, the atomizer being connected to the power supply unit, and the power supply unit having a second air inlet communicating with the first air inlet.

[0018] The aforementioned atomizer and electronic atomizing device include an oil storage component within the atomizer's housing assembly. The top wall of the oil storage component and the inner wall of the housing assembly form a first oil storage chamber, while the oil storage component itself encloses a second oil storage chamber. Furthermore, a liquid flow channel is provided on the inner wall of the housing assembly where it contacts the oil storage component and / or on the side wall of the oil storage component. The first oil storage chamber connects to the second oil storage chamber through this liquid flow channel, allowing a small portion of the e-liquid in the first oil storage chamber to flow into the smaller second oil storage chamber. This slows down the flow rate of the e-liquid. When external air pressure or temperature changes, the atomizing component only needs to withstand a small amount of liquid pressure, making it less likely for e-liquid to leak from the atomizing chamber to the outside of the atomizer. Therefore, the risk of leakage is reduced. With a simple structure and low manufacturing cost, this solution addresses the leakage problem common in existing pre-filled electronic atomizing devices or open-filling electronic atomizing devices due to pressure imbalances within and outside the oil storage chamber.

[0035] One embodiment of this application provides an electronic atomizing device for heating an atomizing medium stored inside the device to form an aerosol for a user to inhale.

[0036] 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.

[0037] 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 A top view of the electronic atomizing device 10 is shown. Figure 3 and 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 201 that is connected to the first air inlet 101. The power supply unit 200 supplies power to the atomizer 100, which heats the e-liquid stored within itself under the power supplied by the power supply unit 200, 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 201, 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.

[0038] In one embodiment, such as Figure 3 and Figure 4 As shown, the atomizer 100 includes a housing assembly 110 and an atomizing assembly 120. The atomizing assembly 120 is disposed within the housing assembly 110. A first air inlet 101 and an air outlet 102 are located at opposite ends of the housing assembly 110. The housing assembly 110 stores e-liquid, which can flow into the atomizing assembly 120 and be heated and atomized into an aerosol. Specifically, in conjunction with... Figure 5 As shown, the atomizing assembly 120 includes an atomizing tube 121 and an atomizing core 122. The atomizing tube 121 forms an air passage 103 that connects the first air inlet 101 and the air outlet 102. The atomizing core 122 is disposed within the air passage 103. In one specific embodiment, the atomizing core 122 includes breathable oil-guiding cotton and a heating element connected to the oil-guiding cotton. The oil-guiding cotton is cylindrical, and its outer peripheral surface is attached to and covers the tube wall of the atomizing tube 121. The inner side of the oil inlet 105 is open, and the oil-guiding cotton surrounds the atomizing chamber 104. The heating element is attached to the inner wall of the oil-guiding cotton (i.e., the cavity wall of the atomizing chamber 104). The atomizing chamber 104 is connected to the first air inlet 101 and the air outlet 102 through the atomizing tube 121. The atomizing tube 121 has an oil inlet 105 at the position corresponding to the atomizing core 122. The oil inlet 105 connects the inner cavity of the housing assembly 110 and the atomizing core 122. The oil-guiding cotton is made of fiber cotton and has the functions of breathability, oil locking and oil guiding. So when the electronic atomizing device 10 is working, the e-liquid in the housing assembly 110 can enter the oil-guiding cotton of the atomizing core 122 through the oil inlet 105, so that it can be heated by the heating element and form an aerosol in the atomizing chamber 104. The aerosol flows out from the air outlet 102 through the air passage 103 for the user to inhale.

[0039] It should be noted that the inner side of the oil inlet 105 is relative to the atomizing tube 121. The inside of the atomizing tube 121 is defined as the inner side, and the outside of the atomizing tube 121 is defined as the outer side.

[0040] However, regarding the above embodiments, as described in the background section, some large-capacity pre-filled e-cigarette devices 10 and open-filled e-cigarette devices 10 have appeared on the market. Although the above-mentioned types of e-cigarette devices 10 have the advantage of large e-liquid capacity, since the volume of the e-liquid storage chamber is much larger than the volume of the atomizing chamber 104, when the external air pressure or temperature changes, the internal pressure of the e-liquid storage chamber may be higher than the external air pressure, causing the atomizing core 122 to be subjected to a large air pressure difference. As a result, the e-liquid is prone to leak from the atomizing chamber 104 to the outside of the e-cigarette device 10 under the action of the air pressure difference, affecting the user's experience.

[0041] Therefore, as an improvement to the above embodiments, please refer again. Figures 3 to 5 The atomizer 100 also includes an oil storage component 130 disposed within the housing assembly 110, an atomizing component 120 disposed within the oil storage component 130, a side wall of the oil storage component 130 attached to the inner wall of the housing assembly 110, a first oil storage chamber 106 formed by the top wall of the oil storage component 130 and the inner wall of the housing assembly 110, and a second oil storage chamber 107 formed by the oil storage component 130. Preferably, the volume of the second oil storage chamber 107 is smaller than the volume of the first oil storage chamber 106. An oil inlet 105 on the atomizing tube 121 connects to the second oil storage chamber 107, and a liquid flow channel 108 is provided on the side wall of the oil storage component 130. The liquid flow channel 108 extends along the side wall of the oil storage component 130, and the first oil storage chamber 106 is connected to the second oil storage chamber 107 through the liquid flow channel 108.

[0042] More specifically, the oil storage assembly 130 includes a bracket 131 and a seal 132 made of, for example, silicone material. One end of the bracket 131 is open, and the seal 132 is connected to the bracket 131 and closes the opening. The second oil storage chamber 107 is formed by the inner wall of the bracket 131 and one side of the seal 132. The liquid flow channel 108 is opened on the side wall of the bracket 131. One end of the atomizing tube 121 is connected to the seal 132, and the other end is connected to the end of the bracket 131 away from the seal 132.

[0043] Thus, it can be seen that by setting the oil storage component 130, the inner cavity of the housing component 110 is divided into two cavities: the first oil storage cavity 106 and the second oil storage cavity 107. This allows some of the e-liquid in the first oil storage cavity 106 to flow through the liquid flow channel 108 to the second oil storage cavity 107 and then into the atomizer core 122. As a result, when the external air pressure or temperature changes, the atomizer core 122 only needs to withstand a small amount of e-liquid pressure, and the e-liquid is less likely to leak from the atomizer cavity 104 to the outside of the electronic atomizer 100 under the action of air pressure difference, thereby reducing the risk of oil leakage.

[0044] It is understood that in other embodiments, the fluid flow channel 108 may also be formed on the inner wall of the housing assembly 110 and the oil storage assembly 130, and this is not limited here.

[0045] Furthermore, in some preferred embodiments, such as Figure 5 and Figure 6 As shown, the top wall of the oil storage assembly 130 (i.e. the top wall of the bracket 131) is provided with an oil passage groove 109, which is connected to the liquid flow channel 108; the side wall of the oil storage assembly 130 (i.e. the side wall of the bracket 131) is provided with an oil passage hole 1010, and the second oil storage chamber 107 is connected to the liquid flow channel 108 through the oil passage hole 1010.

[0046] It is easy to see that a small portion of the e-liquid in the first reservoir 106 first flows into the e-liquid channel 109, then through the spiral-shaped liquid flow channel 108, and finally through the e-liquid hole 1010 into the second reservoir 107. During this process, the e-liquid undergoes two stages of pressure reduction through the e-liquid channel 109 and the liquid flow channel 108, thus gradually reducing the flow rate of the e-liquid and preventing it from exerting a large impact on the atomizer coil 122.

[0047] More preferably, such as Figure 6 and Figure 7 As shown, the liquid flow channel 108 extends spirally along the side wall of the support 131, which prevents the e-liquid from flowing along a straight path, thereby further slowing down the flow rate of the e-liquid. Of course, the liquid flow channel 108 is not limited to extending in a spiral shape; it can also extend along any curved path, as long as it can achieve the purpose of slowing down the flow rate of the e-liquid.

[0048] Furthermore, such as Figure 5 As shown, the second oil storage chamber 107 is provided with oil storage cotton 133. The oil storage cotton 133 is made of the same material as the oil guiding cotton and also has the functions of breathability, oil locking and oil guiding. This allows the e-liquid to be immersed in the oil storage cotton 133 after entering the second oil storage chamber 107. Under the guiding effect of the oil storage cotton 133, it is slowly guided to the atomizing core 122, which can further slow down the flow rate of the e-liquid.

[0049] Furthermore, to facilitate the absorption of e-liquid into the e-liquid 133 after entering the second e-liquid storage chamber 107, the sealing element 132 of the e-liquid storage assembly 130 includes a body 1321 and a protrusion 1322 on one side of the body 1321. Part of the bottom surface of the e-liquid 133 is attached to the protrusion 1322, while the other part of the bottom surface is suspended, so that the suspended bottom surface of the e-liquid 133, one side surface of the body 1321, and the side surface of the protrusion 1322 form an oil guide groove 1011 communicating with the liquid flow channel 108 in the second e-liquid storage chamber 107. In an optional embodiment, the oil guide groove 1011 is formed in a ring shape on the sealing element 132.

[0050] It is evident that by forming the oil guide groove 1011, the e-liquid in the liquid flow channel 108 can accumulate in the oil guide groove 1011 after flowing through the oil passage 1010. Then, under the pressure and siphon effect of the e-liquid, it is guided upward by the oil storage cotton 133 to the oil inlet 105, and then enters the oil guide cotton of the atomizing core 122 from the oil inlet 105. It is easy to understand that since the e-liquid is gathered in the wicking groove 1011 before being absorbed by the e-liquid reservoir 133, the wicking groove 1011 can further slow down the flow rate of the e-liquid as a third-stage pressure reduction structure on the basis of the wicking groove 109 and the liquid flow channel 108. Moreover, because the e-liquid is gathered in the wicking groove 1011, when the e-liquid is absorbed onto the e-liquid reservoir 133 from the bottom, more e-liquid can be absorbed by the e-liquid reservoir 133 at the same time. Compared with the case where the e-liquid is directly absorbed onto the e-liquid reservoir 133 through the wicking hole 1010, the e-liquid can be absorbed onto the e-liquid reservoir 133 more easily.

[0051] Furthermore, as the suction process proceeds, when the e-liquid level in the oil guide groove 1011 drops below the height of the oil passage hole 1010, the e-liquid in the first oil storage chamber 106 will be replenished to the oil guide groove 1011 in a timely manner through the oil passage hole 1010. Therefore, the phenomenon of dry burning and scorching of the coil due to the inability to replenish the e-liquid in time can be avoided.

[0052] It is worth noting that when the user opens the filling plug to fill the first oil reservoir 106 with e-liquid, or when the temperature or air pressure outside the device changes, the air pressure in the first oil reservoir 106 is prone to change, resulting in an air pressure imbalance between the first oil reservoir 106 and the atomizing chamber 104. During the use of the electronic atomizing device 10, the e-liquid in the first oil reservoir 106 will be continuously transferred to the atomizing coil 122 under the action of a continuous air pressure difference. When the transferred e-liquid exceeds the maximum oil-locking capacity of the wicking cotton in the atomizing coil 122, the excess e-liquid will also leak from the atomizing chamber 104 to the outside of the atomizer 100.

[0053] Therefore, in order to completely solve this problem, such as Figure 8 As shown, the atomizing tube 121 has a pressure relief hole 1012 near the air outlet 102, and the second oil storage chamber 107 is connected to the air passage 103 through the pressure relief hole 1012. In an embodiment where an oil storage cotton 133 is provided in the second oil storage chamber 107, the top side of the oil storage cotton 133 and the top wall of the second oil storage chamber 107 form a buffer groove 1013 in the second oil storage chamber 107, and the buffer groove 1013 is connected to the air passage 103 through the pressure relief hole 1012. The purpose of forming the buffer groove 1013 is that if a large amount of gas needs to be discharged, the gas can be temporarily buffered in the buffer groove 1013 and then discharged through the pressure relief hole 1012, thereby avoiding the situation where the gas cannot be discharged in time, which is conducive to further ensuring the balance of air pressure.

[0054] It should be noted that the structure of the oil storage assembly 130 is not limited to the structure described in the above embodiments. It is understood that the oil storage assembly 130 can also form more cavities, so that the inner cavity of the housing assembly 110 is divided into multiple smaller oil storage cavities, which is more conducive to slowing down the flow rate of e-liquid.

[0055] Please continue reading. Figure 3 In terms of the structure of the housing assembly 110, the housing assembly 110 includes a housing 111 and a base 112, wherein one end of the housing 111 is open and the base 112 closes the opening, and the first air inlet 101 extends through the opposite sides of the base 112. One side of the base 112 is connected to the power supply unit 200 by snap-fit ​​or magnetic connection, and the other side of the base 112 and the side of the sealing member 132 of the oil storage assembly 130 away from the second oil storage chamber 107 form an oil suction chamber 1014. The oil suction chamber 1014 is connected to the first air inlet 101, the air passage 103 and the atomizing chamber 104, and the oil suction chamber 1014 is filled with an oil suction element 140 made of the same fiber cotton, so that the aerosol generated in the atomizing chamber 104 can be absorbed by the oil suction element 140 after cooling and turning into condensate, thereby preventing the condensate from leaking from the first air inlet 101 into the power supply unit 200.

[0056] As for the structure of the power supply unit 200, the power supply unit 200 includes a battery, a circuit board, an airflow sensor, etc. Its specific structure can be referred to the existing technology, and will not be described in detail here.

[0057] In summary, the electronic atomizing device 10 provided in this application reduces the risk of oil leakage by gradually decreasing the pressure impact of the e-liquid in the oil storage chamber on the atomizing core 122. Under the premise of simple structure and low manufacturing cost, it solves the problem of oil leakage that is prone to occur 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.

[0058] 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.

[0059] 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.
