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 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. When powered on, the e-liquid in the reservoir is heated and atomized, 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] A housing assembly having an oil storage chamber inside, and the housing assembly having a first air inlet and an air outlet;

[0007] Both the atomizing component and the pressure reducing component are disposed within the housing assembly. The atomizing component has an atomizing chamber that connects the first air inlet and the air outlet, and the atomizing component has an oil inlet that connects to the atomizing chamber.

[0008] The pressure-reducing component includes an outer cover and a breathable first oil-guiding cotton. The outer cover is fitted onto the atomizing component and forms an installation cavity with the outer wall of the atomizing component. The first oil-guiding cotton is disposed in the installation cavity. A pressure-reducing cavity is opened inside the outer cover. The pressure-reducing cavity is connected to the oil storage cavity and is connected to the atomizing cavity in sequence through the first oil-guiding cotton and the oil inlet.

[0009] In one embodiment, the outer cover includes a cover body and a collar. The cover body is coaxially sleeved on the atomizing component, and the mounting cavity is formed by the inner wall of the cover body and the outer wall of the atomizing component. The collar is connected to the cover body and coaxially sleeved on one end of the cover body near the bottom of the oil storage cavity. The pressure relief cavity is formed by the outer wall of the cover body and the inner wall of the collar.

[0010] The collar has a first oil passage hole, the cover has a second oil passage hole, the oil storage cavity is connected to the pressure relief cavity through the first oil passage hole, and the pressure relief cavity is connected to the mounting cavity through the second oil passage hole.

[0011] In one embodiment, the outer wall of the collar has a protrusion that protrudes outward along the radial direction of the collar, and the first oil passage hole penetrates the protrusion along the radial direction of the collar.

[0012] In one embodiment, the housing assembly includes a housing and a lower seal, the air outlet is located at one end of the housing, the end of the housing away from the air outlet has an opening, the lower seal is connected to the atomizing assembly and the end of the outer cover away from the air outlet and closes the opening, and the first air inlet extends through opposite sides of the lower seal.

[0013] In one embodiment, the lower seal includes a body and a protrusion on one side of the body. A portion of the bottom surface of the first oil-guiding cotton is attached to the protrusion, while another portion of the bottom surface is suspended, such that the suspended bottom surface of the first oil-guiding cotton, one side surface of the body, and the side surface of the protrusion form an oil-guiding groove communicating with the pressure-reducing chamber within the mounting cavity.

[0014] In one embodiment, the pressure reducing component has an air guide groove that extends along the axial direction of the atomizing component and connects to the atomizing chamber.

[0015] In one embodiment, the pressure reducing assembly further includes an upper seal, which is connected to the housing assembly and to one end of the outer cover near the air outlet. The upper seal also has an exhaust groove, one end of which is connected to the atomizing chamber and the other end of which is connected to the air guide groove.

[0016] In one embodiment, the upper seal and the first oil-guiding cotton are spaced apart along the axial direction of the atomizing component, such that the surface of the upper seal away from the air outlet and the surface of the first oil-guiding cotton away from the first air inlet form a buffer groove, and the air guide groove and the exhaust groove are connected through the buffer groove.

[0017] In one embodiment, the first oil-guiding cotton has a through hole that extends radially through the first oil-guiding cotton.

[0018] 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.

[0019] The aforementioned atomizer and electronic atomizing device include a pressure-reducing component within the atomizer. A pressure-reducing chamber, connecting to the e-liquid storage chamber, is formed within the outer casing of the pressure-reducing component. A first wicking cotton is placed between the outer casing and the mounting cavity formed by the atomizing component. The pressure-reducing chamber connects to the atomizing chamber via the first wicking surface and an inlet hole on the atomizing component. This allows some of the e-liquid in the storage chamber to flow into the smaller pressure-reducing chamber and be absorbed by the first wicking cotton, thus slowing down the e-liquid flow. When external air pressure or temperature changes, the atomizing core only needs to withstand a small liquid pressure, preventing e-liquid from leaking from the atomizing chamber to the outside of the electronic atomizer. This reduces the risk of leakage. With a simple structure and low manufacturing cost, this solution addresses the leakage problem common in existing pre-filled or open-fill electronic atomizing devices due to pressure imbalances within and outside the storage chamber.

[0039] 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.

[0040] 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.

[0041] See Figures 1 to 3 , 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 An exploded view 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.

[0042] 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 housing assembly 110 has an oil reservoir 103 for containing e-liquid. A first air inlet 101 and an air outlet 102 are located at opposite ends of the housing assembly 110. The atomizing assembly 120 is disposed within the housing assembly 110. Figure 2As shown, the atomizing assembly 120 includes an atomizing tube 121 and an atomizing core 122 disposed in the atomizing tube 121 and electrically connected to the power supply unit 200. In one embodiment, the atomizing core 122 includes a breathable second oil-guiding cotton and a heating element connected to the second oil-guiding cotton. The second oil-guiding cotton is cylindrical, and its outer peripheral surface is attached to the tube wall of the atomizing tube 121 and covers the inner opening of the oil inlet 104. The second oil-guiding cotton forms an atomizing cavity 1221. The heating element is attached to the inner wall of the second oil-guiding cotton (i.e., the cavity wall of the atomizing cavity 1221). The atomizing cavity 1221 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 104 at a position corresponding to the atomizing core 122. The oil inlet 104 connects the oil storage cavity 103 and the atomizing core 122. The second oil-guiding cotton is made of fiber cotton, which has the functions of breathability, oil locking and oil guiding. When the electronic atomizing device 10 is working, the e-liquid in the oil storage chamber 103 can enter the second oil-guiding cotton of the atomizing core 122 through the oil inlet 104, so that it can be heated by the heating element and form an aerosol in the atomizing chamber 1221. The aerosol flows out from the air outlet 102 through the atomizing tube 121 for the user to inhale.

[0043] It should be noted that the inner side of the oil inlet 104 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.

[0044] However, regarding the above embodiments, as described in the background section, some large-capacity pre-filled e-cigarette devices 10 and open-filling 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 storage capacity, since the volume of the e-liquid storage chamber 103 is much larger than the volume of the atomizing chamber 1221, when the external air pressure or temperature changes, the internal pressure of the e-liquid storage chamber 103 may be higher than the external air pressure. This may cause the e-liquid to flow faster, resulting in a greater impact force of the e-liquid on the atomizing components. Consequently, under the action of the air pressure difference, the e-liquid is more likely to leak from the atomizing chamber 1221 to the outside of the e-cigarette device 10, affecting the user's experience.

[0045] Therefore, as an improvement to the above embodiments, such as Figure 3 , Figure 4 and Figure 5As shown, the atomizer 100 also includes a pressure-reducing assembly 130 disposed within the housing assembly 110. The pressure-reducing assembly 130 includes an outer cover 131 and a first oil-guiding cotton 132. The outer cover 131 is fitted onto the atomizing tube 121 of the atomizing assembly 120, and the outer cover 131 and the outer wall of the atomizing assembly 120 (i.e., the outer wall of the atomizing tube 121) form an installation cavity 105. The first oil-guiding cotton 132 is a hollow cylinder and is disposed in the installation cavity 105. It is made of the same material as the second oil-guiding cotton and also has the functions of breathability, oil locking, and oil guiding. A pressure-reducing cavity 106 is opened inside the outer cover 131. The pressure-reducing cavity 106 is connected to the oil storage cavity 103 and is connected to the atomizing cavity 1221 in sequence through the first oil-guiding cotton 132 and the oil inlet hole 104.

[0046] Specifically, in one embodiment, such as Figure 6 As shown, the outer cover 131 includes a cover body 1311 and a collar 1312. The cover body 1311 has a cylindrical structure and is coaxially fitted onto the atomizing assembly 120. The mounting cavity 105 is formed by the inner wall of the cover body 1311 and the outer wall of the atomizing tube 121 in the atomizing assembly 120. The outer wall of the first oil-guiding cotton 132 is attached to the inner wall of the cover body 1311, and the inner wall of the first oil-guiding cotton 132 is attached to the outer wall of the atomizing tube 121. The collar 1312 is annular, with its side away from the bottom of the oil storage cavity 103 connected to the cover body 1311 and coaxially fitted onto the end of the cover body 1311 near the bottom of the oil storage cavity 103. The pressure relief cavity 106 is formed by the outer wall of the cover body 1311 and the inner wall of the collar 1312. The collar 1312 has a first oil passage hole 107, and the cover body 1311 has a second oil passage hole 108. Figure 7 and Figure 8 As shown, the oil storage chamber 103 is connected to the pressure reducing chamber 106 through the first oil passage 107, and the pressure reducing chamber 106 is connected to the mounting chamber 105 through the second oil passage 108.

[0047] In the embodiment shown in the figure, two first oil passage holes 107 are provided, and the two first oil passage holes 107 are arranged opposite each other along the radial direction of the cover 1311. One second oil passage hole 108 is provided, which is arranged between the two first oil passage holes 107 in the circumferential direction of the cover 1311. It can be understood that there is no limitation on the number of first oil passage holes 107 and the number of second oil passage holes 108, and they can be any number.

[0048] It is easy to see that, since the diameters of the first oil passage 107 and the second oil passage 108 are both small, and the volume of the pressure relief chamber 106 is much smaller than that of the oil storage chamber 103, within a fixed period of time, only a small portion of the e-liquid in the oil storage chamber 103 can enter the pressure relief chamber 106 through the first oil passage 107. Then, only a small portion of the e-liquid in the pressure relief chamber 106 can enter the first oil guide cotton 132 in the mounting chamber 105. This causes the e-liquid flow rate to decrease gradually, and then it gradually penetrates into the first oil guide cotton 132 at a slower speed, so that the first oil guide cotton 132 is gradually and completely permeated by the e-liquid. Then, the first oil guide cotton 132 guides the e-liquid to the position of the oil inlet 104.

[0049] Thus, due to the above settings, the flow rate of e-liquid is slowed down, thereby reducing the impact force on the atomizer core 122 when the e-liquid flows. As a result, when the external air pressure or temperature changes, the atomizer core 122 only needs to withstand a small liquid pressure, and the e-liquid is less likely to leak from the atomization chamber 1221 to the outside of the electronic atomizer 100 under the action of air pressure difference, thus reducing the risk of oil leakage.

[0050] Preferably, based on the above embodiments, refer to Figure 6 and Figure 7 The outer wall of the collar 1312 has protrusions 1313 that protrude radially outward from the collar 1312. The number of protrusions 1313 is consistent with the number of first oil passage holes 107. The first oil passage holes 107 penetrate the protrusions 1313 radially through the collar 1312. By providing the protrusions 1313, a smaller pressure relief groove 109 is formed between the protrusions 1313 and the side wall of the housing 111, which is more conducive to reducing the flow rate of e-liquid.

[0051] As can be seen in the embodiment shown in the figure, the e-liquid sequentially enters the mounting cavity 105 through the pressure relief groove 109, the first oil passage hole 107, the pressure relief chamber 106, and the second oil passage hole 108, and then seeps into the first oil-guiding cotton 132. During this process, the e-liquid undergoes four levels of pressure relief. However, it is understood that the structure of the pressure relief assembly 130 is not limited to the structure described in the above embodiment. That is, the number of pressure relief chambers 106 can be two or more. Multiple pressure relief chambers 106 are arranged sequentially along the radial direction of the outer cover 131. The pressure relief chambers 106 located at the beginning and end are respectively adjacent to the oil storage chamber 103 and the mounting cavity 105, so that the e-liquid can undergo more levels of pressure relief. There is no specific limitation.

[0052] Furthermore, in the structure of the housing assembly 110, such as Figures 2 to 4As shown, the housing assembly 110 includes a housing 111, a lower seal 112, and a bottom cover 113. One end of the housing 111 is open. The lower seal 112 is connected to the end of the atomizing tube 121 and the outer cover 131 away from the air outlet 102 and closes the opening. The bottom cover 113 is connected to the side of the lower seal 112 opposite to the air outlet. The end of the housing 111 away from the base has a mouthpiece 1111, and the air outlet 102 is located at the mouthpiece 1111. A first air inlet 101 penetrates the bottom cover 113 and the lower seal 112. The lower seal 112 is preferably made of silicone and forms an oil reservoir 103 with the inner wall of the housing 111 to seal the e-liquid in the oil reservoir 103. The bottom cover 113 is preferably made of plastic and supports the silicone lower seal 112.

[0053] Preferably, in order to allow the e-liquid to enter the mounting cavity 105 from the second oil passage 108 and be more easily absorbed onto the first oil-retaining cotton, such as... Figure 8 As shown, the lower seal 112 includes a body 1121 and a boss 1122 on one side of the body 1121. Part of the bottom wall of the first oil-guiding cotton 132 is attached to the boss 1122, and the other part of the bottom surface is suspended, so that the suspended bottom surface of the first oil-guiding cotton 132, one side surface of the body 1121 and the side surface of the boss 1122 form an oil guide groove 1010 in the mounting cavity 105 that communicates with the pressure relief cavity 106.

[0054] Combined Figure 5 As shown, by forming the wicking groove 1010, the e-liquid in the pressure relief chamber 106 can accumulate in the wicking groove 1010 after flowing through the second wicking hole 108. Then, under the pressure and siphon effect of the e-liquid, it is guided upward by the first guide cotton to the wicking hole 104, and then enters the second guide cotton of the atomizer core 122 from the wicking hole 104. It can be clearly seen that because the e-liquid accumulates in the wicking groove 1010, more e-liquid can be absorbed by the first guide cotton 132 at the same time when it is absorbed from the bottom. Compared with the case where the e-liquid is directly absorbed by the first guide cotton 132 through the second wicking hole 108, the e-liquid can be absorbed by the first guide cotton 132 more easily.

[0055] It is worth noting that when the user opens the filling plug to add e-liquid to the e-liquid reservoir 103, or when the temperature or air pressure outside the device changes, the air pressure in the e-liquid reservoir 103 is prone to change, resulting in an air pressure imbalance between the e-liquid reservoir 103 and the atomizing chamber 1221. During the use of the electronic atomizing device 10, the e-liquid in the e-liquid reservoir 103 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 e-liquid retention capacity of the atomizing coil 122, the excess e-liquid will also leak from the atomizing chamber 1221 to the outside of the atomizer 100.

[0056] Therefore, in order to completely solve this problem, such as Figure 5 As shown, the pressure reducing component 130 has an air guide groove 1011. The air guide groove 1011 extends along the axial direction of the atomizing component 120 and connects to the atomizing chamber 1221. In this way, when the pressure difference between the oil storage chamber 103 and the atomizing chamber 1221 is unbalanced, the high-pressure airflow can overflow from the air guide groove 1011 into the atomizing chamber 1221 and then be discharged to the external environment. This can achieve pressure difference balance between the oil storage chamber 103 and the atomizing chamber 1221 and solve the problem of oil leakage caused by the pressure imbalance inside and outside the oil storage chamber 103.

[0057] It should be noted that there can be multiple embodiments of the pressure reducing assembly 130 having the air guide groove 1011, for example... Figure 5 As shown, the outer peripheral surface of the first oil-guiding cotton 132 is attached to the inner wall of the cover 1311, and the inner peripheral surface is attached to the outer wall of the atomizing tube 121. Therefore, the air guide groove 1011 is formed in the first oil-guiding cotton 132 and passes through the opposite ends of the first oil-guiding cotton 132 in the vertical direction shown in the figure. In another embodiment, the outer wall of the first oil-guiding cotton 132 may not be attached to the inner wall of the cover 1311, but the air guide groove 1011 is formed by the outer wall of the first oil-guiding cotton 132 and the inner wall of the cover 1311.

[0058] Regarding the structure of how the air guide groove 1011 connects to the atomizing chamber 1221, such as... Figure 4 , Figure 5 and Figure 9 As shown, the pressure-reducing assembly 130 also includes an upper seal 133, which is connected to the housing assembly 110 and to the end of the cover 1311 of the outer cover 131 near the air outlet 102. Specifically, the end of the housing 111 away from the base (i.e., the inner side of the nozzle 1111) has a connecting post 1112 extending toward the interior of the housing 111. One side of the upper seal 133 is connected to the connecting post 1112, and the other side is connected to the cover 1311. At the same time, the upper seal 133 has an exhaust groove 1331, one end of which is connected to the atomizing chamber 1221, and the other end is connected to the air guide groove 1011.

[0059] More specifically, such as Figure 10As shown, a first insertion hole 1332 is provided on one side of the upper seal 133, and a second insertion hole 1333 is provided on the other side. The first insertion hole 1332 and the second insertion hole 1333 are interconnected and pass through the upper seal 133. The connecting post 1112 is inserted into the first insertion hole 1332, and one end of the atomizing tube 121 is inserted into the second insertion hole 1333. The exhaust groove 1331 includes a first sub-exhaust groove 1331a and a second sub-exhaust groove 1331b that are interconnected. The first sub-exhaust groove 1331a is opened on the surface of the upper seal 133 on the side where the second insertion hole 1333 is opened and extends radially along the upper seal 133. The second sub-exhaust groove 1331b is opened on the wall of the second insertion hole 1333 and extends axially along the upper seal 133. Since the part of the atomizing tube 121 inserted into the second insertion hole 1333 does not contact the connecting post 1112, therefore, combined with Figure 9 There is a gap between the two connecting the atomizing chamber 1221 and the air outlet 102. The high-pressure airflow flowing out from the air guide groove 1011 can pass through the first sub-exhaust groove 1331a and the second sub-exhaust groove 1331b in sequence and enter the atomizing tube 121, and then be discharged to the external environment from the air outlet 102 or through the first air inlet 101 and the second air inlet 201.

[0060] As a preferred embodiment, such as Figure 11 As shown, the upper seal 133 and the first oil-guiding cotton 132 are spaced apart along the axial direction of the atomizing assembly 120, such that a buffer groove 1012 is formed on the surface of the upper seal 133 away from the air outlet 102 and the surface of the first oil-guiding cotton 132 away from the first air inlet 101. The air guide groove 1011 and the exhaust groove 1331 are connected through the buffer groove 1012. The purpose of forming the buffer groove 1012 is that if a large amount of gas needs to be discharged, the gas can be temporarily buffered in the buffer groove 1012 and then discharged through the exhaust groove 1331, thereby avoiding the situation where the gas cannot be discharged in time, which is conducive to further ensuring the balance of air pressure.

[0061] Additionally, see Figure 3 In one embodiment, the first oil-guiding cotton 132 is further provided with a through hole 1321 that extends radially through the first oil-guiding cotton 132. By providing the through hole 1321, the flow rate of e-liquid in the first oil-guiding cotton 132 can be slowed down to a certain extent, so as to further reduce the pressure exerted by the e-liquid on the atomizing core 122.

[0062] 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.

[0063] In summary, the electronic atomizing device 10 provided in this application reduces the risk of leakage by gradually decreasing the pressure impact of the e-liquid in the oil storage chamber 103 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 103.

[0064] 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.

[0065] 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.
