Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a microporous atomizer. Background Technology

[0002] Currently, microporous atomizers mainly consist of a reservoir for storing liquids such as essential oils and an atomizer body for atomizing these liquids. Before use, the reservoir needs to be sealed to the liquid inlet on the atomizer body, primarily through a sealing ring on the reservoir. However, in actual use, it has been found that because the sealing ring is made of soft rubber, tightening it further after contact between the reservoir and the sealing ring increases the pressure inside the reservoir, exceeding atmospheric pressure. Consequently, when the atomizer is used upright, liquids such as essential oils are squeezed out through the micropores on the atomizing plate and accumulate on its surface, preventing proper atomization and significantly impacting the user experience. Utility Model Content

[0003] This application provides a microporous atomizer, which aims to improve the technical problem that existing microporous atomizers often have atomizing plates that cannot properly atomize essential oils.

[0004] Therefore, this application provides a microporous atomizer, including a liquid storage bottle, a pressure regulating module, and an atomizer body, wherein,

[0005] The atomizer body has a built-in atomization channel, which has a liquid inlet and a mist outlet, and the liquid inlet and the mist outlet are respectively exposed on the surface of the atomizer body;

[0006] The liquid storage bottle is sealed to the liquid inlet to form a pressure regulating space in conjunction with the cavity wall of the atomizing channel;

[0007] The air pressure regulating module is located at least partially on the cavity wall of the atomizing channel. When the atomizer body switches from an inverted state to an upright state, the air pressure regulating module is used to regulate the air pressure in the pressure regulating space from a first air pressure to a second air pressure, the second air pressure being lower than the air pressure of the environment where the microporous atomizer is located.

[0008] Optionally, in some embodiments of this application, the pressure regulating module is a deformable shape, at least a portion of which constitutes part of the cavity wall of the atomizing channel, and at least a portion of which has a first deformation state and a second deformation state, wherein the first deformation state gives the pressure regulating space a first volume, and the second deformation state gives the pressure regulating space a second volume.

[0009] When the atomizer body is in an inverted state, at least a portion of the deformable body switches to the first deformation state, so that the pressure regulating space has the first air pressure. When the atomizer body is in an upright state, at least a portion of the deformable body switches to the second deformation state, so that the pressure regulating space has the second air pressure.

[0010] Optionally, in some embodiments of this application, the deformable body includes a pressure regulating membrane and a counterweight. The pressure regulating membrane forms part of the cavity wall of the atomizing channel, and the counterweight is mounted on the pressure regulating membrane. When the atomizer body is in an inverted state, the pressure regulating membrane switches to the first deformation state under the gravity of the counterweight. When the atomizer body is in an upright state, the pressure regulating membrane switches to the second deformation state under the gravity of the counterweight.

[0011] Optionally, in some embodiments of this application, the pressure regulating module is a movable body, at least part of which forms part of the cavity wall of the atomizing channel, and at least part of which has a first movable position and a second movable position, wherein the first movable position gives the pressure regulating space a first volume, and the second movable position gives the pressure regulating space a second volume.

[0012] When the atomizer body is in an inverted state, at least a portion of the movable body moves to the first movable position, so that the pressure regulating space has the first air pressure. When the atomizer body is in an upright state, at least a portion of the movable body moves to the second movable position, so that the pressure regulating space has the second air pressure.

[0013] Optionally, in some embodiments of this application, the movable body includes an air pressure regulating plate and a lever. The air pressure regulating plate forms part of the cavity wall of the atomizing channel. One end of the lever is linked to the air pressure regulating plate, and the other end of the lever is exposed on the surface of the atomizer body. When the atomizer body is in an inverted state, the air pressure regulating plate moves to the first active position under the action of the lever. When the atomizer body is in an upright state, the air pressure regulating plate moves to the second active position under the action of the lever.

[0014] Optionally, in some embodiments of this application, the atomizer body includes a housing, the housing having a top opening and a side opening, a liquid storage bottle bracket having the atomization channel is installed inside the top opening, at least a portion of the liquid inlet coincides with the top opening, and at least a portion of the mist outlet coincides with the side opening.

[0015] Optionally, in some embodiments of this application, the atomizing channel includes a first channel segment having the liquid inlet and a second channel segment having the mist outlet. The first channel segment extends vertically, and the second channel segment extends horizontally. The end of the first channel segment away from the liquid inlet is connected to the end of the second channel segment away from the mist outlet.

[0016] Optionally, in some embodiments of this application, the first channel segment has a first cavity wall that is vertically facing the liquid inlet, and the air pressure regulating module is a deformable or movable body, at least a portion of the deformable or the movable body constituting all or part of the structure of the first cavity wall.

[0017] Optionally, in some embodiments of this application, the second channel segment has a second cavity wall disposed at the bottom of the atomizer body in a vertical direction, and the air pressure regulating module is a deformable or movable body, at least a portion of the deformable or the movable body constituting all or part of the structure of the second cavity wall.

[0018] Optionally, in some embodiments of this application, the atomizer body further includes an atomizing module, which includes a microporous atomizing plate and a control circuit board with a control switch;

[0019] The microporous atomizing plate is placed in the atomizing channel and is positioned adjacent to the mist outlet.

[0020] The control circuit board is placed inside the housing and is electrically connected to the microporous atomizing sheet. The control switch is at least partially exposed on the surface of the housing.

[0021] The microporous atomizer provided in this application embodiment, through the above-described structural configuration, adds an air pressure regulating module compared to existing microporous atomizers. This air pressure regulating module is at least partially located on the cavity wall of the atomization channel. When the atomizer body switches from an inverted state to an upright state, this air pressure regulating module can adjust the air pressure within the pressure regulating space formed by the sealed connection between the liquid storage bottle and the liquid inlet from a first air pressure to a second air pressure. This second air pressure is lower than the air pressure of the environment where the microporous atomizer is located. Thus, when the atomizer... When the device is in the upright position, the air pressure in the pressure regulating space can be adjusted by the air pressure regulating module to be lower than the air pressure of the environment where the microporous atomizer is located, so that the pressure regulating space is in a negative pressure state. At this time, due to the effect of negative pressure, liquids such as essential oils in the pressure regulating space can no longer be squeezed out from the micropores on the atomizing plate near the mist outlet. This avoids the problem of liquids such as essential oils accumulating on the surface of the atomizing plate, which would prevent the atomizing plate from properly atomizing liquids such as essential oils, thus improving the user experience.

Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0035] The atomization of a microporous atomizer mainly utilizes the microporous atomization principle of the microporous atomizing plate. This involves inputting oscillating pulses into the drive circuit, causing the microporous atomizing plate to oscillate at high speed. This causes liquid particles to overcome surface tension, separating from the liquid surface and exiting from the mist-exit side of the microporous atomizing plate to form a "mist." Simultaneously, air enters the liquid-absorbing side of the microporous atomizing plate through its micropores to achieve air pressure balance.

[0036] Common microporous atomizers on the market mainly consist of a reservoir for storing liquids such as essential oils and an atomizer body for atomizing these liquids. Before use, the reservoir needs to be sealed to the liquid inlet on the atomizer body, primarily through a sealing ring on the reservoir. However, in actual use, it has been found that because the sealing ring is made of soft rubber, tightening it further after contact between the reservoir and the sealing ring increases the pressure inside the reservoir, exceeding atmospheric pressure. Consequently, when the atomizer is used upright, liquids such as essential oils are forced out through the micropores on the atomizing plate and accumulate on its surface, preventing proper atomization and significantly impacting the user experience.

[0037] Therefore, it is necessary to provide a microporous atomizer to improve the technical problem that existing microporous atomizers often have atomizing plates that cannot properly atomize essential oils.

[0038] Please see Figures 1 to 5 The microporous atomizer 10 provided in this application embodiment will now be described. The microporous atomizer 10 includes a liquid storage bottle 11, a pressure regulating module 12, and an atomizer body 13. The atomizer body 13 has a built-in atomization channel 14, which has a liquid inlet 141 and a mist outlet 142, both exposed on the surface of the atomizer body 13. The liquid storage bottle 11 is sealed to the liquid inlet 141 to form a pressure regulating space in conjunction with the cavity wall of the atomization channel 14. The pressure regulating module 12 is at least partially located on the cavity wall of the atomization channel 14. When the atomizer body 13 is switched from an inverted state to an upright state, the pressure regulating module 12 adjusts the pressure in the pressure regulating space from a first pressure to a second pressure, which is lower than the ambient air pressure of the microporous atomizer 10.

[0039] It is understood that the microporous atomizer 10 in this application embodiment is mainly used for atomizing liquids such as essential oils. Therefore, the aforementioned liquid storage bottle 11 is mainly used for storing liquids such as essential oils, and it can be any structure and shape that facilitates the storage of liquids such as essential oils, including but not limited to common glass bottle structures, metal bottle structures, plastic bottle structures, etc.

[0040] The atomizer body 13 mentioned above is specifically the main structure of the microporous atomizer 10 in this application embodiment. That is, the atomization operation performed by the microporous atomizer 10 is mainly completed by the atomizer body 13. When the liquid storage bottle 11 is sealed and connected to the liquid inlet 141, the liquid in the liquid storage bottle 11 enters the atomization channel 14 and is then atomized by the atomizer body 13 to form a "spray" that is sprayed out through the mist outlet 142 of the atomization channel 14.

[0041] Specifically, the sealing connection between the liquid storage bottle 11 and the liquid inlet 141 mentioned above can be achieved by using a threaded structure for fastening, while a first sealing ring 15 is also provided at the connection point. After the liquid storage bottle 11 and the liquid inlet 141 are sealed together, the liquid storage bottle 11 can cooperate with the cavity wall of the atomizing channel 14 to form a pressure regulating space. That is, the pressure regulating space is mainly formed by the internal space of the atomizing channel 14 through the liquid storage bottle 11 covering the liquid inlet 141.

[0042] Generally speaking, the liquid storage bottle 11 and atomizer body 13 mentioned above are basically the same as the liquid storage bottle 11 and atomizer body 13 of the prior art microporous atomizer 10. That is, the main difference between the microporous atomizer 10 of this application embodiment and the prior art microporous atomizer 10 is that the microporous atomizer 10 of this application embodiment adds a pressure regulating module 12. The pressure regulating module 12 can be a conventional pressure regulating device, which is located at least partially in the cavity wall of the atomization channel 14. It uses conventional pressure regulating methods such as evacuating the pressure regulating space, changing the temperature in the pressure regulating space, and changing the volume in the pressure regulating space to adjust the pressure in the pressure regulating space from the first pressure to the second pressure when the atomizer body 13 is switched from the inverted state to the upright state, and makes the second pressure lower than the air pressure of the environment where the microporous atomizer 10 is located.

[0043] Thus, the microporous atomizer 10 provided in this embodiment, through the above-described structural configuration, adds a pressure regulating module 12 compared to the prior art microporous atomizer 10. This pressure regulating module 12 is at least partially located on the cavity wall of the atomization channel 14. When the atomizer body 13 switches from an inverted state to an upright state, the pressure regulating module 12 can regulate the pressure within the pressure regulating space formed by the sealed connection between the liquid storage bottle 11 and the liquid inlet 141 from a first pressure to a second pressure. This second pressure is lower than the ambient air pressure of the microporous atomizer 10. Therefore, when the atomizer body 13 is in the upright position for use, the air pressure in the pressure regulating space can be adjusted by the air pressure regulating module 12 to be lower than the air pressure of the environment where the microporous atomizer 10 is located, so that the pressure regulating space is in a negative pressure state. At this time, due to the effect of negative pressure, liquids such as essential oils in the pressure regulating space can no longer be squeezed out from the micropores on the atomizing plate near the mist outlet 142. This can avoid the problem of liquids such as essential oils accumulating on the surface of the atomizing plate, causing the atomizing plate to be unable to properly atomize liquids such as essential oils, thereby improving the user experience.

[0044] In some examples, such as Figures 2 to 5 As shown, the air pressure regulating module 12 is specifically a deformable shape, at least a portion of which constitutes part of the cavity wall of the atomizing channel 14. The at least portion of the deformable shape has a first deformation state and a second deformation state. The first deformation state gives the pressure regulating space a first volume, and the second deformation state gives the pressure regulating space a second volume. When the atomizer body 13 is in an inverted state, at least a portion of the deformable shape switches to the first deformation state, giving the pressure regulating space a first air pressure. When the atomizer body 13 is in an upright state, at least a portion of the deformable shape switches to the second deformation state, giving the pressure regulating space a second air pressure.

[0045] Thus, through the above structural configuration, when the atomizer body 13 is switched from an inverted state to an upright state, at least part of the deformable body can be switched from a first deformation state to a second deformation state, so that the volume of the pressure regulating space changes from the first volume to the second volume, and the air pressure in the pressure regulating space is adjusted from the first air pressure to the second air pressure.

[0046] It is understood that the deformable form in this example specifically refers to structures such as thin films that have different deformation states and can freely switch between these different deformation states. Generally, it is preferred to set it as follows: Figure 1 , Figure 2 and Figure 3 As shown, when the atomizer body 13 is in an inverted state, at least a portion of the deformable shape is in a first deformed state. At this time, the liquid storage bottle 11 is... Figure 1 The status shown has switched to Figure 2 and Figure 3 The sealed connection shown with the atomizer body 13 creates a pressure-regulating space with a first volume. The air pressure within this space is a first air pressure, which is generally slightly higher than the ambient air pressure of the microporous atomizer 10. Next, the atomizer body 13... Figure 2 The inverted state shown has been switched to Figure 4 In the upright position shown, the deformable body can be switched from a first deformation state to a second deformation state by at least a portion of the deformable body, so that the pressure regulating space has a second volume. At this time, the air pressure in the pressure regulating space is the second air pressure. In order to make the pressure regulating space a negative pressure state, the second air pressure should be less than the air pressure of the environment where the microporous atomizer 10 is located. Therefore, the second air pressure is generally less than the first air pressure. So in this example, the second volume should be greater than the first volume. For this purpose, the first deformation state should be a state in which at least a portion of the deformable body is deformed toward the inside of the atomization channel 14, so that the volume of the internal space (i.e., the pressure regulating space) of the atomization channel 14 becomes smaller. The second deformation state should be a state in which at least a portion of the deformable body is deformed toward the outside of the atomization channel 14, so that the volume of the internal space (i.e., the pressure regulating space) of the atomization channel 14 becomes larger.

[0047] In some examples, such as Figures 2 to 5 As shown, the deformable variant may specifically include a pressure regulating membrane 121 and a counterweight 122. The pressure regulating membrane 121 forms part of the cavity wall of the atomizing channel 14, and the counterweight 122 is installed on the pressure regulating membrane 121. When the atomizer body 13 is in the position of Figure 2 In the inverted state shown, the pressure regulating diaphragm 121 switches to the first deformation state under the gravity of the counterweight 122, while the atomizer body 13 is in the inverted state. Figure 4 When in the upright position shown, the pressure regulating membrane 121 switches to the second deformation state under the gravity of the counterweight 122.

[0048] Thus, through the above structural arrangement, when the atomizer body 13 is in the position Figures 1 to 3 In the inverted state shown, the pressure regulating diaphragm 121 is in the first deformation state under the gravity of the counterweight 122 (i.e., Figures 1 to 3 (as shown, the atomizing channel 14 is deformed inwards), so that the internal space of the atomizing channel 14 has a first volume. At this time, if the liquid storage bottle 11 is deformed inwards... Figure 1 The status shown has switched to Figure 2 and Figure 3 The state shown, where the atomizer body 13 is sealed together, forms a corresponding pressure-regulating space. The air pressure within this space can be a first air pressure slightly greater than the ambient air pressure of the microporous atomizer 10. Then, when the atomizer body 13 is... Figure 2 The inverted state shown has been switched to Figure 4 In the upright position shown, the pressure regulating diaphragm 121 can switch from the first deformation state to the second deformation state under the gravity of the counterweight 122 (i.e., Figure 4 and Figure 5 As shown, the atomizing channel 14 is deformed outwards, which increases the volume of the internal space of the atomizing channel 14 (i.e., the main part of the pressure regulating space) and adjusts the air pressure in the pressure regulating space from the first air pressure to the second air pressure, which is lower than the air pressure of the environment where the microporous atomizer 10 is located, so as to avoid the problem of liquids such as essential oils accumulating on the surface of the atomizing plate, which would prevent the atomizing plate from properly atomizing liquids such as essential oils. Meanwhile, during the upright use of this microporous atomizer 10, when the temperature of the environment where the microporous atomizer 10 is located rises, the softening characteristic of the pressure regulating membrane 121 at high temperatures can increase the deformation of the pressure regulating membrane 121 in the second deformation state. This can offset the pressure increase in the pressure regulating space caused by thermal expansion. In this way, it can be ensured that the pressure in the pressure regulating space is always lower than the air pressure of the environment where the microporous atomizer 10 is located during the upright use of this microporous atomizer 10, so as to avoid the problem of liquids such as essential oils accumulating on the surface of the atomizing plate, which would prevent the atomizing plate from properly atomizing liquids such as essential oils.

[0049] It is understood that the pressure regulating membrane 121 in this example can be any one of polyurethane (TPU) film, polytetrafluoroethylene (PTFE) film, or metallized film (such as aluminized polyester). The counterweight 122 in this example can be a metal block or a non-metal block (such as a cement block or concrete block) with a certain weight, which can switch the pressure regulating membrane 121 to the first deformation state or the second deformation state through the action of gravity in different directions.

[0050] In some examples, the pressure regulating module 12 may specifically be a movable body, at least a portion of which forms part of the cavity wall of the atomizing channel 14. The movable body has at least a first movable position and a second movable position. The first movable position gives the pressure regulating space a first volume, and the second movable position gives the pressure regulating space a second volume. When the atomizer body 13 is in an inverted state, at least a portion of the movable body moves to the first movable position, giving the pressure regulating space a first air pressure. When the atomizer body 13 is in an upright state, at least a portion of the movable body moves to the second movable position, giving the pressure regulating space a second air pressure.

[0051] Thus, with the above structural configuration, when the atomizer body 13 is switched from an inverted state to an upright state, at least part of the movable body can move from the first movable position to the second movable position, so that the volume of the pressure regulating space changes from the first volume to the second volume, and at the same time, the air pressure in the pressure regulating space is adjusted from the first air pressure to the second air pressure.

[0052] It is understood that, in this example, the movable body specifically refers to a structure such as a plate that can serve as part of the cavity wall of the atomizing channel 14, and is movably connected to other parts of the cavity wall of the atomizing channel 14, such as by sliding. Generally, it is preferably configured such that, when the atomizer body 13 is in an inverted state, at least a portion of the movable body is located in a first active position, at which time the liquid storage bottle 11 is... Figure 1 The status shown has switched to Figure 2 and Figure 3 The sealed connection shown with the atomizer body 13 creates a pressure-regulating space with a first volume. The air pressure within this space is a first air pressure, which is generally slightly higher than the ambient air pressure of the microporous atomizer 10. Next, the atomizer body 13... Figure 2 The inverted state shown has been switched to Figure 4 In the upright position shown, at least a portion of the movable body can move from the first movable position to the second movable position, so that the pressure regulating space has a second volume. At this time, the air pressure in the pressure regulating space is the second air pressure. In order to keep the pressure regulating space in a negative pressure state, the second air pressure should be less than the air pressure of the environment where the microporous atomizer 10 is located. Therefore, the second air pressure is generally less than the first air pressure. Thus, in this example, the second volume should be greater than the first volume. For this purpose, the first movable position should be the final position reached by at least a portion of the movable body moving towards the inside of the atomization channel 14, so that the volume of the internal space (i.e., the pressure regulating space) of the atomization channel 14 becomes smaller. The second movable position should be the final position reached by at least a portion of the movable body moving towards the outside of the atomization channel 14, so that the volume of the internal space (i.e., the pressure regulating space) of the atomization channel 14 becomes larger.

[0053] In some examples, the movable body may specifically include an air pressure regulating plate and a lever. The air pressure regulating plate forms part of the cavity wall of the atomizing channel 14. One end of the lever is linked to the air pressure regulating plate, and the other end of the lever is exposed on the surface of the atomizer body 13. When the atomizer body 13 is in an inverted state, the air pressure regulating plate moves to a first active position under the action of the lever. When the atomizer body 13 is in an upright state, the air pressure regulating plate moves to a second active position under the action of the lever.

[0054] Thus, through the above structural arrangement, when the atomizer body 13 is in the position Figures 1 to 3 In the inverted state shown, the pressure regulating plate is in the first active position when moved by the lever, so that the internal space of the atomizing channel 14 has a first volume. At this time, if the liquid storage bottle 11 is... Figure 1 The status shown has switched to Figure 2 and Figure 3 The state shown, where the atomizer body 13 is sealed together, forms a corresponding pressure-regulating space. The air pressure within this space can be a first air pressure slightly greater than the ambient air pressure of the microporous atomizer 10. Then, when the atomizer body 13 is... Figure 2 The inverted state shown has been switched to Figure 4 When in the upright position shown, the air pressure regulating plate can move from the first active position to the second active position under the reverse action of the lever, which increases the volume of the internal space of the atomizing channel 14 (i.e. the main part of the pressure regulating space) and adjusts the air pressure in the pressure regulating space from the first air pressure to the second air pressure, which is lower than the air pressure of the environment where the microporous atomizer 10 is located, so as to avoid the problem of liquids such as essential oils accumulating on the surface of the atomizing plate, which would prevent the atomizing plate from properly atomizing liquids such as essential oils.

[0055] It is understood that the air pressure regulating plate in this example can be any of the following: a metal plate, a plastic plate, a ceramic plate, or a composite material plate (such as carbon fiber reinforced plastic, metal-plastic composite, etc.). In this example, one end of the lever is preferably linked to the side surface of the air pressure regulating plate located outside the atomization channel 14 to avoid affecting the sealing performance within the atomization channel 14.

[0056] In some examples, such as Figure 1As shown, the atomizer body 13 may specifically include a housing 131. The housing 131 has a top opening and a side opening. A liquid storage bottle 11 bracket with an atomization channel 14 is installed inside the top opening. At least a portion of the liquid inlet 141 coincides with the top opening, and at least a portion of the mist outlet 142 coincides with the side opening. Thus, through the above structural arrangement, the liquid storage bottle 11 bracket with the atomization channel 14 can be detached from the housing 131, allowing for separate replacement or maintenance of the liquid storage bottle 11 bracket in the future, thereby reducing replacement or maintenance costs.

[0057] It is understandable that when the atomizer body 13 in this example is in Figure 4 In the upright position shown, the top opening in this example refers to... Figure 4 The opening shown is located on the upper end face of the atomizer body 13.

[0058] In this example, the side opening refers to... Figure 4 The openings shown are located on the left and right sides of the atomizer body 13, and the side openings are preferably located at the end closer to the top opening, so as to optimize the structural setting of the atomization channel 14.

[0059] In some examples, such as Figures 2 to 5 As shown, the atomizing channel 14 includes a first channel section 143 with a liquid inlet 141 and a second channel section 144 with a mist outlet 142. The first channel section 143 extends vertically, and the second channel section 144 extends horizontally. The end of the first channel section 143 away from the liquid inlet 141 is connected to the end of the second channel section 144 away from the mist outlet 142.

[0060] Thus, through the above structural arrangement, the corresponding atomizing channel 14 can be arranged more reasonably in the support of the liquid storage bottle 11, so that the atomizing channel 14 can better realize the connection between the liquid inlet 141 located at the top of the outer shell 131 and the mist outlet 142 located on the side of the outer shell 131.

[0061] It is understood that the vertical direction in this example generally refers to the height direction of the atomizer body 13, that is, the direction from the top opening of the atomizer body 13 to the bottom of the atomizer body 13, i.e. Figure 3 The image shows the vertical direction of the atomizer body 13 when it is inverted. In this example, the horizontal direction generally refers to the width of the atomizer body 13, which is perpendicular to the vertical direction in this example. Figure 3 The atomizer body 13 shown is in an inverted state, with its left and right directions.

[0062] In some examples, such as Figures 2 to 5As shown, the first channel section 143 has a first cavity wall that is vertically aligned with the liquid inlet 141. The air pressure regulating module 12 is a deformable or movable body, and at least a portion of the deformable or movable body constitutes the entire or part of the structure of the first cavity wall.

[0063] Thus, through the above structural arrangement, when the air pressure regulating module 12 is deformable, it can be... Figure 3 The deformable variant shown deforms towards the inside of the first channel segment 143, and while in the first deformed state, it can also be... Figure 5 The deformable body shown can deform outwards from the first channel segment 143 to reach a second deformed state. When the air pressure regulating module 12 is a movable body, it can move inwards from the first channel segment 143 to reach a first active position, or it can move outwards from the first channel segment 143 to reach a second active position.

[0064] Understandably, with Figures 2 to 5 The air pressure regulating module 12 shown is a deformable example. Specifically, this deformable body may include an air pressure regulating membrane 121 and a counterweight 122. The first cavity wall has an opening. The air pressure regulating membrane 121 is fixed by the pressing of the regulating membrane plate 123, covering and installing on the opening to form the entire or part of the structure of the first cavity wall. The counterweight 122 is built into the air pressure regulating membrane 121, or fixedly disposed on the surface of the air pressure regulating membrane 121 away from the first channel section 143. Thus, when the atomizer body 13 is in... Figure 2 In the inverted state shown, the air pressure regulating diaphragm 121 can, under the action of the counterweight 122, such as Figure 3 As shown, it deforms towards the inside of the first channel segment 143, and is in the first deformation state, while the atomizer body 13 is in... Figure 4 In the upright position shown, the air pressure regulating diaphragm 121 can, under the action of the counterweight 122, such as Figure 5 As shown, it deforms outward toward the first channel segment 143, and is in the second deformation state.

[0065] In some examples, such as Figures 2 to 5 As shown, the second channel segment 144 has a second cavity wall (i.e., a cavity wall) disposed vertically adjacent to the bottom of the atomizer body 13. Figure 5 The second channel section 144 is located in the lower cavity wall), and the air pressure regulating module 12 is a deformable or movable body. At least part of the deformable or movable body constitutes all or part of the structure of the second cavity wall.

[0066] Thus, with the above structural arrangement, when the air pressure regulating module 12 is deformable, it can deform inward toward the second channel section 144, and in the first deformed state, it can also be... Figure 5 The deformable body shown deforms outward toward the second channel segment 144, and is in a second deformed state. When the air pressure regulating module 12 is a movable body, it can move inward toward the second channel segment 144 to eventually reach the first active position, or it can move outward toward the second channel segment 144 to eventually reach the second active position.

[0067] It is understandable that, taking the air pressure regulating module 12 as an example of a deformable body, the deformable body may specifically include an air pressure regulating membrane 121 and a counterweight 122. The second cavity wall has an opening, and the air pressure regulating membrane 121 is fixed by the pressing of the regulating membrane plate 123, covering and installing on the opening to form the entire or part of the structure of the second cavity wall. The counterweight 122 is built into the air pressure regulating membrane 121, or fixedly disposed on the surface of the air pressure regulating membrane 121 away from the second channel section 144. Thus, when the atomizer body 13 is in... Figure 2 In the inverted state shown, the pressure regulating diaphragm 121 can deform towards the inside of the second channel section 144 under the action of the counterweight 122, and is in the first deformation state. Meanwhile, when the atomizer body 13 is in... Figure 4 When in the upright position shown, the air pressure regulating membrane 121 can deform towards the outside of the second channel section 144 under the action of the counterweight 122, and is in the second deformation state.

[0068] In some examples, the atomizer body 13 further includes an atomizing module 133, which includes a microporous atomizing plate 1331 and a control circuit board 1333 having a control switch 1332. The microporous atomizing plate 1331 is placed in the atomizing channel 14 and is disposed adjacent to the mist outlet 142. The control circuit board 1333 is placed in the housing 131 and is electrically connected to the microporous atomizing plate 1331, and the control switch 1332 is at least partially exposed on the surface of the housing 131.

[0069] Thus, with the above structural configuration, the control circuit board 1333 can effectively drive the microporous atomizing plate 1331 to perform the corresponding atomization operation under the control of the control switch 1332.

[0070] It is understood that in this example, the microporous atomizing plate 1331 can be installed and fixed in the atomizing channel 14 through the atomizing plate bracket 16, and a second sealing ring 17 can be provided at the connection between the atomizing plate bracket 16 and the microporous atomizing plate 1331 and / or at the connection between the atomizing plate bracket 16 and the atomizing channel 14 to ensure the sealing performance of the corresponding connection.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
