Technical Field
[0001] This application relates to the field of electronic cigarette technology, and more particularly to an electronic cigarette atomizing device and an electronic cigarette. Background Technology
[0002] As a healthy and convenient consumer product, e-cigarettes have gained popularity in recent years, and their use is becoming increasingly widespread. E-cigarettes work by atomizing e-liquid to provide users with inhalable vapor. To facilitate portability and use, the internal structure of e-cigarettes is designed to be very compact.
[0003] However, the limited internal space makes it difficult for the negative pressure generated in the e-liquid reservoir during inhalation to restore the internal and external pressure balance through gas circulation. This leads to problems such as poor e-liquid supply and burnt coils, which not only greatly reduces the user experience but also easily damages the e-cigarette. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this application provides an electronic cigarette atomizing device and an electronic cigarette having the atomizing device. By opening a ventilation channel in the upper cover of the electronic cigarette atomizing device, the oil storage tank and the atomizing tank of the electronic cigarette atomizing device are connected. Thus, the oil storage tank and the atomizing tank can achieve airflow balance through the ventilation channel, so that the e-liquid in the oil storage tank can continuously flow to the atomizing component of the electronic cigarette atomizing device to be heated and generate smoke.
[0005] This application provides an electronic cigarette atomizing device, comprising a housing, an oil storage tank, an upper cover, an atomizing component, and a lower cover. The housing has an air outlet channel, and the lower cover is connected to the housing and has an air inlet channel. The upper cover and the atomizing component are located within the housing, forming a receiving cavity. The atomizing component is located within the receiving cavity and is used to heat and atomize the liquid in the oil storage tank. An atomizing chamber is formed between the atomizing component and the lower cover, and the atomizing chamber is connected to both the air outlet channel and the air inlet channel. The upper cover has a sidewall with a ventilation channel. The sidewall facing the housing is the outer surface, and the sidewall facing the atomizing component is the inner surface. The ventilation channel penetrates both the inner and outer surfaces of the sidewall and is connected to both the oil storage tank and the atomizing chamber.
[0006] This application also provides an electronic cigarette, which includes the aforementioned electronic cigarette atomizing device.
[0007] The electronic cigarette atomizing device and electronic cigarette provided in this application connect the oil storage tank and the atomizing tank by opening a ventilation channel on the upper cover. Thus, the oil storage tank and the atomizing tank can achieve airflow balance through the ventilation channel, allowing the e-liquid in the oil storage tank to flow continuously until the atomizing component is heated to produce smoke, thus solving problems such as poor e-liquid supply and burnt coil.

[0031] For clarity, the various parts in the accompanying drawings of this application are not drawn to scale. Furthermore, some well-known parts may not be shown in the drawings.
[0032] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electronic smoke atomizing device 100 provided in the embodiments of this application. Figure 2 for Figure 1 An exploded view of the electronic cigarette atomizing device 100. (See diagram below.) Figure 1 and Figure 2 As shown, the electronic cigarette atomizing device 100 includes a housing 1, an upper cover 2, an atomizing component 3, a lower cover 4, and an oil storage tank 5. The housing 1 has an air outlet channel 10. The lower cover 4 is connected to the housing 1 and has an air inlet channel 41. The upper cover 2 and the atomizing component 3 are located inside the housing 1, forming a receiving cavity. The atomizing component 3 is located within the receiving cavity and is used to heat and atomize the liquid in the oil storage tank 5. An atomizing chamber 6 is formed between the atomizing component 3 and the lower cover 4, and the atomizing chamber 6 is connected to both the air outlet channel 10 and the air inlet channel 41. The top cover 2 has a side wall, on which a ventilation channel 8 is provided. The side surface of the side wall facing the housing 1 is the outer surface, and the side surface of the side wall facing the atomizing component 3 is the inner surface. The ventilation channel 8 penetrates the inner surface and the outer surface of the side wall and is connected to the oil storage tank 5 and the atomizing tank 6 respectively.
[0033] The electronic cigarette atomizing device 100 provided in this application embodiment connects the oil storage chamber 5 and the atomizing chamber 6 by opening an air exchange channel 8 on the upper cover 2. Thus, the oil storage chamber 5 and the atomizing chamber 6 can achieve airflow balance through the air exchange channel 8, allowing the e-liquid in the oil storage chamber 5 to continuously flow to the atomizing component 3, where it is heated to produce smoke for the user to inhale. This solves problems such as poor e-liquid supply and burnt coils in the atomizing component 3, and improves the user experience.
[0034] The atomizing component 3 includes a porous body 31, a lead wire 32, and a heating element (not shown in the figure). The porous body 31 has a liquid absorption surface 311 and an atomizing surface 312. According to one embodiment of this application, the liquid absorption surface 311 and the atomizing surface 312 are arranged opposite to each other. The liquid absorption surface 311 is closer to the oil storage tank 5 than the atomizing surface 312. The heating element is disposed on the atomizing surface 312. The space between the atomizing surface 312 and the lower cover 4 forms the atomizing chamber 6.
[0035] The ventilation channel 8 extends through the sidewall of the upper cover 2 along the direction from the outer surface to the inner surface of the sidewall. In some embodiments, the ventilation channel 8 may be linear (e.g., ...). Figure 1 (as shown) or curved (such as) Figure 3 (As shown). The inner wall of the ventilation channel 8 may also be provided with a first groove 81 (as shown). Figure 4 As shown in the figure, the ventilation channel 8 can store a certain amount of liquid matrix, so that the liquid matrix in the oil storage tank 5 is not easy to enter the atomization chamber 6 through the ventilation channel 8.
[0036] The number of ventilation channels 8 is at least one. When there are multiple ventilation channels 8, the multiple ventilation channels 8 can be equally spaced on the side wall of the upper cover 2 so that the airflow between the oil storage tank 5 and the atomizing tank 6 can circulate through the multiple ventilation channels 8 that are evenly arranged.
[0037] The shape of the ventilation channel 8 can be circular, elliptical, oval, rectangular, trapezoidal, or other polygonal shapes, etc., and is not limited here. The shape refers to the shape of the cross-section taken from the aperture direction of the ventilation channel 8.
[0038] The ventilation channel 8 has an aperture of 0.2mm-3mm, which allows the liquid matrix in the oil storage tank 5 to leak into the atomizing chamber 6 as little as possible when the outside air enters the oil storage tank 5 through the ventilation channel 8.
[0039] The oil storage tank 5 is used to contain a liquid matrix, such as e-liquid. The atomizing component 3 is used to heat and atomize the liquid matrix into an aerosol, such as smoke.
[0040] The ventilation channel 8 includes a first end and a second end, the first end of which penetrates the inner surface of the side wall of the upper cover 2 and communicates with the oil storage tank 5, and the second end of the ventilation channel 8 penetrates the outer surface of the side wall of the upper cover 2 and communicates with the atomizing chamber 6.
[0041] The side wall of the upper cover 2, the lower cover 4, and the shell 1 cooperate to form an airflow channel 7, which is connected to the second end of the ventilation channel 8 and the atomizing chamber 6.
[0042] In some embodiments, the upper cover 2 includes a first part 21 and a second part 22, at least a portion of the second part 22 is fitted onto the atomizing component 3, the sidewall of the second part 22, the lower cover 4 and the housing 1 cooperate to form the airflow channel 7, the first part 21 is located on the side of the second part away from the lower cover 4 and the outer surface of the sidewall of the first part abuts against the inner wall of the housing 1.
[0043] The electronic cigarette atomizing device 100 further includes a conductive pin 9, which passes through the lower cover 4 and is connected to the lead wire 32 of the atomizing component 3. The conductive pin 9 is used to electrically connect the atomizing component 3 and the power source. According to one embodiment of this application, the first part of the lead wire 32 of the atomizing component 3 is embedded in the porous body 31 and forms an electrical connection with the heating element. The second part of the lead wire 32 abuts against the conductive pin 9 to form an electrical connection. The second part of the lead wire 32 is connected to the first part to form an L-shape. The liquid matrix stored in the oil storage tank 5 enters the interior of the porous body 31 through the liquid absorption surface 311 and is conducted to the atomizing surface 312. Under the action of the heating element, it vaporizes to form an aerosol and enters the atomizing chamber 6. According to an embodiment of this application, the porous body 31 is a porous ceramic matrix.
[0044] Among them, such as Figure 1 and Figure 2 As shown, the electronic cigarette atomizing device 100 further includes a first sealing element 14. The first sealing element 14 includes a sealing element body 141, which is sleeved on the outer edge of the upper cover 2 and abuts against the inner wall of the housing 1 to form a seal, preventing the liquid matrix in the oil storage tank 5 from leaking into the atomizing chamber 6. The sealing element body 141 includes a sealing top cover 1411 and a first side wall 1412. The sealing top cover 1411 is sleeved on the surface of the upper cover 2 facing the air outlet channel 10, and the first side wall 1412 abuts against the side wall of the upper cover 2. In this embodiment, the first sealing element 14 only includes the sealing element body 141.
[0045] Among them, such as Figure 1and Figure 2 As shown, the electronic cigarette atomizing device 100 further includes a second sealing element 15, which includes a second sidewall 152 and a sealing edge 151 extending from the second sidewall 152. The second sidewall 152 is fitted onto the outer edge of the atomizing assembly 3 and abuts against the inner surface of the sidewall of the upper cover 2 to form a seal, thereby preventing the liquid matrix in the oil storage tank 5 from leaking into the atomizing chamber 6.
[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the electronic cigarette atomizing device 100 also includes a lower cover seal 18, which surrounds the side wall of the lower cover 4 and abuts against the inner wall of the housing 1, preventing the liquid matrix in the atomizing chamber 6 from leaking to the outside of the lower cover 4 and contaminating other components of the electronic cigarette.
[0047] The air outlet channel 10 is axially arranged along the housing 1 and communicates with the atomizing chamber 6. The air inlet channel 41 communicates with both the outside environment and the atomizing chamber 6. During the user's inhalation of the electronic cigarette, outside air enters the atomizing chamber 6 through the air inlet channel 41, mixes with the aerosol in the atomizing chamber 6, and then enters the user's mouth through the air outlet channel 10. In one embodiment of this application, both the air outlet channel 10 and the air inlet channel 41 are directly opposite the atomizing component 3.
[0048] Understandably, as the liquid matrix gradually enters the porous body 31 to form an aerosol, the air pressure in the oil storage tank 5 gradually decreases to below the external atmospheric pressure. Since the side wall of the upper cover 2 has the ventilation channel 8, external air enters the oil storage tank 5 through the atomizing chamber 6 and the ventilation channel 8, achieving airflow balance between the atomizing chamber 6 and the oil storage tank 5 (e.g., Figure 5 As shown by the arrow, Figure 5 for Figure 1 (Enlarged view of A in the middle), so that the e-liquid in the oil storage tank 5 can continuously flow to the porous body 31 to ensure atomization efficiency.
[0049] In some embodiments, such as Figure 1 As shown, the ventilation channel 8 is directly connected to the oil storage tank 5 and the airflow channel 7, so that the atomizing chamber 6 is connected to the oil storage tank 5 through the airflow channel 7 and the ventilation channel 8.
[0050] In some embodiments, the extending direction of the ventilation channel 8 is parallel to the first direction or has a preset angle with the first direction, for example, 5°, 10°, 15°, 30°, 45°, 55°, 65°, 75°, or 85°, wherein the first direction is parallel to the atomizing surface 312, such as... Figure 1 The X-axis direction is shown.
[0051] According to one embodiment of this application, the shortest distance between the ventilation channel 8 and the surface of the upper cover 2 away from the lower cover 4 is 0.05mm-0.4mm, so that the liquid matrix in the ventilation channel 8 will not leak from the ventilation channel 8 to the atomizing chamber 6 under the action of surface tension.
[0052] In some embodiments, the electronic cigarette atomizing device 100 further includes at least one elastic element, which can close and open the ventilation channel. When the air pressure in the oil storage tank 5 is greater than or equal to the external atmospheric pressure, the at least one elastic element covers at least one of the first and second ends of the ventilation channel 8 to close the ventilation channel 8; when the air pressure in the oil storage tank 5 is less than the external atmospheric pressure, the at least one elastic element deforms to open the ventilation channel 8. The elastic element is made of a material capable of elastic deformation, such as silicone or rubber.
[0053] Figure 6 This is a schematic diagram of the structure of an electronic smoke atomizing device 100 provided in another embodiment of this application. Figure 7 for Figure 6 Exploded view of the electronic cigarette atomizing device 100. Figure 9 for Figure 6 A schematic diagram of the structure of the first sealing element 14 of the electronic cigarette atomizing device 100. Figure 10 This is a side view of the first seal 14. (As shown) Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, in some embodiments, the first sealing element 14 includes the sealing element body 141 and a spring piece 142, which constitutes at least one elastic element. The spring piece 142 extends from the end of the first sidewall 1412 near the lower cover 4 toward the lower cover 4. When the air pressure in the oil storage tank 5 is greater than or equal to the external atmospheric pressure, the spring piece 142 covers the second end of the ventilation channel 8 to close the ventilation channel 8; when the air pressure in the oil storage tank 5 is less than the external atmospheric pressure, the spring piece 142 deforms toward the housing 1 to open the ventilation channel 8. The first sealing element 14 can be integrally formed, or the sealing element body 141 and the spring piece 142 can be fixedly connected by adhesive or other means to form the first sealing element 14. In one embodiment of this application, the first sealing element 14 is an upper cover sealing element.
[0054] According to one embodiment of this application, the spring 142 includes a first portion 1421 and a second portion 1422. The second end of the ventilation channel 8 extends to the airflow channel 7 and is covered by the first portion 1421 of the spring 142, thus blocking the airflow channel 7. The second portion 1422 of the spring 142 extends from the end of the first portion 1421 away from the oil storage tank 5 and is angled to the outer surface of the side wall of the upper cover 2 to form a first gap. The air pressure in the oil storage tank 5... When the pressure difference is less than the external atmospheric pressure, the outside air passes through the atomizing chamber 6 and the airflow channel 7 to reach the first gap, thereby pushing the second part 1422 of the spring 142 towards the housing 1. This causes the first part 1421 of the spring 142 to separate from the second end of the ventilation channel 8, making the ventilation channel 8 connected to the airflow channel 7. This allows the outside air to pass through the atomizing chamber 6 and the ventilation channel 8 into the oil storage tank 5, thereby achieving airflow balance between the atomizing chamber 6 and the oil storage tank 5 (e.g., Figure 8 As shown by the arrow, Figure 8 for Figure 6 (Enlarged view of B in the diagram). The sealing body 141 can be integrally formed with the spring piece 142, or the spring piece 142 can be fixedly connected to the sealing body 141 by means of snap-fitting, adhesive bonding, etc.
[0055] In some embodiments, with the extension direction from the liquid-absorbing surface 311 to the atomizing surface 312 as the second direction, the outer contour of the first sealing member 14 projected onto a plane perpendicular to the second direction is elliptical or racetrack-shaped. The outer contour of the first sealing member 14 projected onto a plane perpendicular to the second direction has two opposite long sides and two opposite short sides. The number of spring pieces 142 can be at least one, and the at least one spring piece 142 is distributed on the short sides. When the number of spring pieces 142 is two, the two spring pieces 142 can be symmetrically distributed on the two opposite short sides. In other embodiments, the at least one spring piece 142 can also be distributed on the long sides. When the number of spring pieces 142 is two or more, the spring pieces 142 can also be simultaneously distributed on the long sides and the short sides. According to one embodiment of this application, the number of spring pieces 142 is two or four, and the spring pieces 142 are symmetrically distributed on the two opposite long sides and the two opposite short sides.
[0056] Obviously, the outer contour of the first seal 14 as an orthographic projection on a plane perpendicular to the second direction can also be other shapes, such as circles, polygons, etc.
[0057] In other embodiments of this application, the spring piece 142 can be independently disposed on the side wall of the upper cover 2 and cover the second end of the ventilation channel 8 to close the ventilation channel. For example, the spring piece 142 includes a main body and a protrusion. The side wall of the upper cover 2 is provided with a second groove adapted to the protrusion. The protrusion of the spring piece 142 engages with the second groove of the side wall of the upper cover 2 to achieve a fixed connection between the spring piece 142 and the upper cover 2. It can also be further fixed by adhesive or interference fit. The first part of the main body of the spring piece 142 covers the second end of the ventilation channel 8. The second part of the main body of the spring piece 142 extends from the end of the first part of the main body of the spring piece 142 away from the oil storage tank 5 toward the lower cover 4 and is spaced at an angle with the outer surface of the side wall of the upper cover 2 to form the first gap. When the air pressure in the oil storage chamber 5 is lower than the external atmospheric pressure, external air enters the atomizing chamber 6 through the air intake channel 41, then passes through the airflow channel 7 to reach the first gap, and pushes the second part of the main body of the spring piece 142 toward the housing 1. This causes the first part of the main body of the spring piece 142 to separate from the second end of the ventilation channel 8, making the ventilation channel 8 connected to the airflow channel 7, thereby achieving airflow balance between the atomizing chamber 6 and the oil storage chamber 5. Obviously, the spring piece 142 can also be fixedly connected to the upper cover 2 by riveting, screwing, or other methods.
[0058] Please refer to the following: Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the structure of an electronic smoke atomizing device 100 provided in another embodiment of this application. Figure 12 for Figure 11 An exploded view of the electronic cigarette atomizing device 100. (See diagram below.) Figure 11 and Figure 12 As shown, in some embodiments, the second sealing member 15 includes a sealing edge 151 and a second sidewall 152. The second sidewall 152 includes a lower sidewall 1521 near the lower cover 4 and an upper sidewall 1522 away from the lower cover. The upper sidewall 1522 has a deformable portion 15221, which constitutes the at least one elastic member. When the air pressure of the oil storage tank 5 is greater than or equal to the external atmospheric pressure, the deformable portion 15221 covers the first end of the ventilation channel 8 to close the ventilation channel 8, thus isolating the first end of the ventilation channel 8 from the oil storage tank 5. When the air pressure of the oil storage tank 5 is less than the external atmospheric pressure, the deformable portion 15221 deforms toward the porous body 31 to open the ventilation channel 8. The upper sidewall 1522 can be integrally formed, or the deformable portion 15221 and other parts of the upper sidewall 1522 can be fixedly connected by adhesive or other means to form the upper sidewall 1522.
[0059] In some embodiments, the deformable portion 15221 protrudes from the atomizing component 3 in a direction away from the lower cover 4 and is spaced apart from the upper cover 2. When the air pressure in the oil storage chamber 5 is lower than the external atmospheric pressure, creating a pressure difference, the external air passes through the atomizing chamber 6 and the airflow channel 7 to reach the first end of the ventilation channel 8 and pushes open the deformable portion 15221, so that the first end of the ventilation channel 8 is connected to the oil storage chamber 5, thereby achieving airflow balance between the atomizing chamber 6 and the oil storage chamber 5 (e.g., Figure 13 As shown by the arrow, Figure 13 for Figure 11 (Enlarged view of C in the middle).
[0060] In some embodiments, the extension direction from the liquid-absorbing surface 311 to the atomizing surface 312 is taken as the second direction. The outer contour of the orthographic projection of the second sealing member 15 on a plane perpendicular to the second direction is elliptical or racetrack-shaped. The outer contour of the orthographic projection of the second sealing member 15 on a plane perpendicular to the second direction has two opposite long sides and two opposite short sides. The number of deformable portions 15221 is at least one, and the at least one deformable portion 15221 is distributed on the short side. When the number of deformable portions 15221 is two, the deformable portions 15221 can be symmetrically distributed on the two opposite short sides. In other embodiments, the at least one deformable portion 15221 can also be distributed on the long side. In other embodiments, the number of deformable portions 15221 is two or four, and the deformable portions 15221 are symmetrically distributed on the two opposite long sides. In other embodiments, there are two or more deformable portions 15221, and the deformable portions 15221 are simultaneously distributed on the long side and the short side, or there are four deformable portions 15221, and the deformable portions 15221 are simultaneously distributed on two opposite long sides and two opposite short sides.
[0061] Obviously, the outer contour of the second seal 15 as an orthographic projection on a plane perpendicular to the second direction can also be other shapes, such as circles, polygons, etc.
[0062] Please see Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the structure of the second seal 15 provided in the embodiments of this application. Figure 15 for Figure 14 A side view of the second seal 15. (See attached image.) Figure 14 and Figure 15As shown, in some embodiments, the thickness of the deformable portion 15221 is less than the thickness of other portions of the upper sidewall 1522, or the elastic modulus of the deformable portion 15221 is greater than that of other portions of the upper sidewall 1522, making it easier for the deformable portion 15221 to deform and open the ventilation channel 8. The thickness of the deformable portion 15221 is its dimension in the direction parallel to the liquid absorption surface 311, and the thickness of other portions of the upper sidewall 1522 is its dimension in the direction parallel to the liquid absorption surface 311.
[0063] Please see Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the second seal 15 provided in another embodiment of this application. Figure 17 for Figure 16 A side view of the second seal 15. (See attached image.) Figure 16 and Figure 17 As shown, in some embodiments, the deformable portion 15221 is spaced apart from other parts of the upper sidewall 1522. The deformable portion 15221 may be a tongue-shaped spring. Because the deformable portion 15221 is spaced apart from other parts of the upper sidewall 1522, the outside atmosphere can more easily push the deformable portion 15221 away, thereby opening the ventilation channel 8.
[0064] In other embodiments, the deformable portion 15221 may also be independently disposed on the side wall of the atomizing component 3 and cover the first end of the ventilation channel 8 to close the ventilation channel 8. For example, the deformable portion 15221 includes a main body and a protrusion. The side wall of the atomizing component 3 is provided with a third groove adapted to the protrusion of the deformable portion 15221. The protrusion of the deformable portion 15221 engages with the third groove of the side wall of the atomizing component 3 to achieve a fixed connection between the deformable portion 15221 and the side wall of the atomizing component 3. It can also be further fixed by adhesive or interference fit. The main body of the deformable portion 15221 extends from the end of the protrusion away from the lower cover 4 in a direction away from the lower cover 4 and protrudes from the end of the atomizing component 3 away from the lower cover 4. The main body of the deformable portion 15221 covers the first end of the ventilation channel 8 to close the ventilation channel 8. Obviously, the deformable part 15221 can also be fixedly connected to the atomizing component 3 by means of riveting, screwing, etc. There can be multiple independently provided deformable parts 15221, used to cover the first and second ends of the ventilation channel 8.
[0065] In some embodiments, such as Figure 14 and Figure 16As shown, the deformable part 15221 is arc-shaped, and the orthographic projection of the deformable part 15221 on the liquid absorption surface 311 is located within the area of the liquid absorption surface 311. The curvature center of the deformable part 15221 is located on the side of the deformable part 15221 away from the inner surface of the upper cover 2, so that the air pressure in the oil storage tank 5 is less than the external atmospheric pressure, and when the external air reaches the first end of the ventilation channel 8, it is easier to push open the deformable part 15221 and open the ventilation channel 8.
[0066] Please refer to it again. Figure 1 , Figure 6 and Figure 11 The electronic smoke atomizing device 100 also includes an oil-absorbing cotton 17, which is located in the receiving cavity and around the air inlet channel 41. The oil-absorbing cotton 17 is used to absorb the liquid matrix formed by smoke condensation to prevent the liquid matrix formed by smoke condensation from entering the air outlet channel 10 and entering the user's mouth during the user's inhalation.
[0067] Please see Figure 18 , Figure 18 This is a structural block diagram of the electronic cigarette 200 provided in the embodiments of this application, such as... Figure 18 As shown, the electronic cigarette 200 includes the electronic cigarette atomizing device 100 provided in any of the foregoing embodiments.
[0068] In some embodiments, the electronic cigarette 200 further includes a power supply component, which is electrically connected to the atomizing component 3 via a conductive pin 9 to supply power to the atomizing component 3, thereby heating the liquid matrix in the oil storage tank 5 to form smoke for the user to inhale.
[0069] The electronic cigarette 200 provided in this application embodiment opens an air exchange channel 8 on the upper cover 2 of the electronic cigarette atomizing device 100, so that the oil storage tank 5 and the atomizing tank 6 are connected. Thus, the oil storage tank 5 and the atomizing tank 6 can achieve airflow balance through the air exchange channel 8, so that the e-liquid in the oil storage tank 5 can continuously flow to the atomizing component 3 to be heated and generate smoke, thus solving problems such as poor e-liquid supply and burnt coil of the atomizing component 3.
[0070] The above are the implementation methods of the embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the embodiments of this application, and these improvements and modifications are also considered to be within the protection scope of this application.
