[0036] Before introducing the electronic atomization device provided in the embodiment of the present application in detail, the specific application scenarios of the electronic atomization device are first described in detail:

[0037] Please refer to Figure 1 The electronic atomization device is generally provided with a second channel 21 (air flow channel), a liquid storage portion 22 and a heating element 24. The liquid storage portion 22 stores an atomization matrix. The heating element 24 heats the atomization matrix to form an atomized gas. The user inhales the atomized gas through the first channel 11 in the nozzle 1.

[0038] The low-carbon esters in the atomizing matrix are the main source of aroma when generating atomized gas, but the low-carbon esters are extremely volatile, so that after the electronic atomizing device is opened and used, the aroma in the atomized gas generated by the atomizing matrix will gradually decrease or change over time. Therefore, in the related art, an additional protective cover is added to the outside of the mouthpiece 1, and the protective cover is put on the mouthpiece 1 when the user is not using the electronic atomizing device to prevent the reduction of the aroma. However, the protective cover is easy to be lost or contaminated due to poor storage, which affects the user experience. In order to solve this problem, the present application proposes an electronic atomizing device.

[0039] The electronic atomization device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] In one embodiment, the present application provides an electronic atomization device, please refer to Figure 1 The electronic atomization device mainly includes a nozzle 1, an atomization component 2 and a control component 3. The nozzle 1 is connected to the atomization component 2, and the atomization component 2 is used to generate atomized gas; a first channel 11 is provided in the nozzle 1, and a second channel 21 is provided in the atomization component 2. The first channel 11 is connected to the second channel 21, and the control component 3 is provided in the first channel 11. Please refer to Figure 2 At least two elastic valve pieces 311 are provided in the control member 3, and the at least two elastic valve pieces 311 have a first state in which they are relatively open when the user inhales and a second state in which they are relatively closed after the suction force is removed; in the first state, the at least two elastic valve pieces 311 are relatively open, and the atomized gas in the first channel 11 can be discharged outward from between the opened elastic valve pieces 311; in the second state, the at least two elastic valve pieces 311 are relatively closed, and the elastic valve pieces 311 close the first channel 11.

[0041] In the embodiment of the present application, a first channel 11 is provided in the mouthpiece 1, a second channel 21 is provided in the atomizer assembly 2, the first channel 11 is connected to the second channel 21, a control member 3 is provided in the first channel 11, at least two elastic valve sheets 311 are provided in the control member 3, when at least two elastic valve sheets 311 are relatively opened, the atomized gas generated by the atomizer assembly 2 is discharged outward from the first channel 11; when the user does not use the electronic atomizer device, at least two elastic valve sheets 311 in the control member 3 are relatively closed, the first channel 11 in the mouthpiece 1 is closed, and the aroma in the atomizer assembly 2 is prevented from escaping from the first channel 11. In this way, there is no need to add an additional detachable protective cover to the mouthpiece 1 to prevent the aroma from escaping, and the aroma in the electronic atomizer device can be prevented from escaping when not in use only by the control member 3.

[0042] For specific applications, please refer to Figure 1The nozzle 1 and the atomizer assembly 2 can be fixedly connected; or they can be detachably connected, so that the user can replace the nozzle 1 conveniently. For example, they can be detachably connected by means of magnetism, snaps, threads, silicone interference fit, etc. Those skilled in the art can choose according to actual needs, and the embodiments of the present application are not limited to this.

[0043] Understandably, please refer to Figure 1 When the user inhales the nozzle 1, the atomized gas generated by the atomizing assembly 2 enters the first channel 11 through the second channel 21 and is then inhaled by the user. Figure 2 During this process, the elastic valve sheet 311 is relatively opened by the impact of the airflow of the atomized gas; when the user stops inhaling the mouthpiece 1, the elastic valve sheet 311 rebounds to its original state under the action of its own elasticity and then closes to close the first channel 11, so that the volatilized fragrance in the atomizer assembly 2 will not escape.

[0044] It can be understood that the material of the elastic valve plate 311 includes but is not limited to: food-grade rubber, such as: food-grade silicone; food contact plastic, etc. Those skilled in the art can select according to actual needs, and the embodiments of the present application do not limit this.

[0045] In one embodiment, please refer to Figure 2 The control member 3 includes a deformation portion 31, and a slit 312 is provided in the deformation portion 31 to divide the deformation portion 31 into at least two elastic valve pieces 311; the elastic valve piece 311 is configured to elastically deform toward the outside of the mouthpiece 1 under the suction force of the user in the first state, and to restore the elastic deformation in the second state. Among them, when the elastic valve piece 311 is elastically deformed in a direction away from the atomizer assembly 2, at least two elastic valve pieces 311 are relatively open; when the elastic valve piece 311 is not deformed, at least two elastic valve pieces 311 are relatively closed.

[0046] In the examples of this application, please refer to Figure 2 The slit 312 provided in the deformation part 31 divides the deformation part 31 into at least two elastic valve pieces 311, please refer to Figure 3 When the user draws from the mouthpiece 1, the elastic valve sheet 311 elastically deforms in a direction away from the atomizer assembly 2, so that the elastic valve sheet 311 is relatively open, and the atomized gas generated by the atomizer assembly 2 can smoothly pass through the second channel 21 and the first channel 11 into the user's mouth; when the user stops drawing from the mouthpiece 1, the elastic valve sheet 311 rebounds under its own elasticity, and the elastic valve sheet 311 is relatively closed to close the first channel 11, so that the fragrance in the atomizer assembly 2 cannot escape along the first channel 11. The control member 3 of the embodiment of the present application prevents the escape of fragrance through the deformation portion 31 with a simple structure, and is easy to install and has better versatility.

[0047] For specific applications, please refer to Figure 3 The airflow generated by the user sucking from the mouthpiece 1 causes the elastic valve sheet 311 to deform elastically under the action of the airflow, so that the atomized gas generated by the atomizer assembly 2 can pass through the first channel 11 after the elastic valve sheet 311 is opened; please refer to Figure 4 When the user does not inhale the airflow, the elastic valve sheet 311 rebounds to its original position under its own elastic action to close the first channel 11, blocking the fragrance in the atomization component 2 from escaping from the first channel 11 along the second channel 21, thereby improving the use time and fragrance retention rate of the electronic atomization device.

[0048] In one embodiment, please refer to Figure 2 The control member 3 further includes a connecting portion 32, which is disposed in the first channel 11 and fixedly connected to the mouthpiece 1. The deformable portion 31 is disposed at one end of the connecting portion 32 away from the atomizer assembly 2. A cavity is disposed in the connecting portion 32, and the cavity is communicated with the first channel 11. In some other embodiments, the connecting portion 32 may also be detachably connected to the mouthpiece 1 to achieve detachable connection between the control member 3 and the mouthpiece 1.

[0049] In the examples of this application, please refer to Figure 1 and Figure 2 The connecting portion 32 is fixedly connected to the first channel 11 of the suction nozzle 1. A deformation portion 31 is provided at one end of the connecting portion 32 away from the atomizer assembly 2. A cavity is provided in the connecting portion 32, and the cavity is connected to the first channel 11, so that when the elastic valve sheet 311 in the deformation portion 32 is opened, the first channel 11, the cavity and the second channel 21 form a connected airflow channel, and the atomized gas generated by the atomizer assembly 2 can be inhaled by the user through the airflow channel.

[0050] In a specific application, the external dimensions of the connecting portion 32 match the dimensions of the first channel 11, for example: along the extension direction perpendicular to the first channel 11, that is, the radial direction of the electronic atomization device, when the cross section of the first channel 11 is circular, the cross section of the connecting portion 32 is also circular, and the dimensions are consistent; or, along the extension direction perpendicular to the first channel 11, that is, the radial direction of the electronic atomization device, when the cross section of the first channel 11 is elliptical, the cross section of the connecting portion 32 is also elliptical, and the dimensions are consistent; those skilled in the art can select according to actual needs, and the embodiments of the present application do not limit this. In this way, it is convenient to select according to needs during production.

[0051] It can be understood that the connecting portion 32 is arranged in the first channel 11 and is fixedly connected to the suction nozzle 1. It can be fixedly connected by interference fit between the connecting portion 32 and the inner wall of the first channel 11, or it can be snap-fitted or bonded, etc. Those skilled in the art can choose according to actual needs, and the embodiments of the present application do not limit this.

[0052] In one embodiment, please refer to Figure 2 The connecting part 32 includes a first connecting part 321 and a second connecting part 322, one end of the first connecting part 321 is connected to the deformation part 31, and the other end is connected to the second connecting part 322, a first cavity 3211 is provided in the first connecting part 321, and a second cavity 3221 is provided in the second connecting part 322, and the first cavity 321 is connected to the first channel 11 through the second cavity 3221; along the radial direction of the electronic atomization device, the size of the first cavity 3211 close to the deformation part 31 is larger than the size of the first cavity 3211 close to the second connecting part 322.

[0053] In the embodiment of the present application, one end of the first connecting portion 321 is connected to the deformation portion 31, and the other end is connected to the second connecting portion 322. The first connecting portion 321 and the second connecting portion 322 are respectively adapted to and fixedly connected to different areas of the first channel 11, and along the radial direction of the electronic atomization device, that is, perpendicular to the extension direction of the first channel 11, the size of the first cavity close to the deformation portion 31 is larger than the size of the first cavity 3211 close to the second connecting portion 322. In this way, the size of the first connecting portion 321 toward the nozzle 1 is larger than the size of the other end, which facilitates the installation of the control component 3. At the same time, when the airflow enters the first channel 11 from the second channel 21 and passes through the cavity in the control component 3, turbulence is formed at the first cavity 3211, so that the aroma components and other components in the airflow are fully mixed, and the user has a better taste after inhalation.

[0054] In one embodiment, please refer to Figure 3 , the first cavity 3211 gradually shrinks from the deformation portion 31 to the second connection portion 322 .

[0055] In the embodiment of the present application, the first cavity 3211 gradually shrinks from the deformation portion 31 to the second connection portion 322 , so that the first cavity 3211 has a smooth transition and is more convenient for manufacturing and processing.

[0056] Understandably, please refer to Figure 3 As the first cavity 3211 gradually shrinks, the cavity wall of the first cavity 3211 also shrinks adaptively, and the cavity wall of the first cavity 3211 is adapted to the inner wall of the first channel 11 to facilitate the installation of the control component 3 in the first channel 11.

[0057] Alternatively, when the first cavity 3211 gradually shrinks, the cavity wall of the first cavity 3211 does not shrink, so that the weight of the connecting portion 32 can be increased, so that the control component 3 is more stable after being installed in the first channel 11 and will not be easily loosened by the impact of airflow.

[0058] In one embodiment, please refer to Figure 5A plurality of slits 312 are provided in the deformation portion 31 , and the plurality of slits 312 divide the deformation portion 31 into a plurality of elastic valve sheets 311 .

[0059] exist Figure 5 In the example shown, the number of slits 312 is 6, and the number of elastic valve plates 311 is also 6. In some other embodiments, the number of slits 312 and elastic valve plates 311 may be the same or different, and may be other numbers, which can be set according to actual needs.

[0060] In the examples of this application, please refer to Figure 5 The multiple slits 312 in the deformation portion 31 divide the deformation portion 31 into a plurality of elastic valve pieces 311, thereby increasing the number of the elastic valve pieces 311, so as to facilitate the opening of the elastic valve pieces 311 when impacted by airflow, while also ensuring that the elastic valve pieces 311 rebound under their own elastic action to close the first channel 11.

[0061] It can be understood that the multiple slits 312 can be cross-arranged or spaced apart to form multiple elastic valve sheets 312 in the shape of strips, so that the deformation portion 31 can be easily opened when impacted by airflow while ensuring the sealing of the control component 3 in the closed state. Technical personnel in this field can select according to actual needs, and the embodiments of the present application do not limit this.

[0062] In one embodiment, please refer to Figure 6 , multiple slits 312 intersect each other at one point. And, in Figure 6 In the example shown, the number of slits 312 is 8, and the number of elastic valve plates 311 is also 8. In some other embodiments, the number of slits 312 and elastic valve plates 311 may be the same or different, and may be other numbers, which can be set according to actual needs.

[0063] In the examples of this application, please refer to Figure 6 The multiple slits 312 intersect each other at one point, so that the multiple elastic valve sheets 311 are more easily opened by the impact of airflow at the intersection of the multiple slits 312.

[0064] It can be understood that when the user draws suction from the nozzle 1, the airflow generated is relatively small, and a plurality of slits 312 are provided and intersected at one point, so that when the multiple elastic valve sheets 311 are impacted by the airflow, the intersection of the multiple slits 312 becomes a stress concentration point, so that the multiple elastic valve sheets 311 are easier to open.

[0065] In one embodiment, please refer to Figure 6 , the intersection of the plurality of slits 312 coincides with the center of the deformation portion 31. In the embodiment of the present application, please refer to Figure 6The intersection of the plurality of slits 312 coincides with the center of the deformation portion 31 , so that the center position of the deformation portion 31 becomes a stress concentration point, so that the airflow can more easily impact and open the plurality of elastic valve sheets 311 .

[0066] It can be understood that when the airflow in the first channel 11 impacts the deformation part 31, the center position of the deformation part 31 is the stress concentration point. Therefore, by setting the intersection of multiple slits 312 to coincide with the center of the deformation part 31, after the airflow enters the cavity of the control part through the first channel 11, it is easier to open the multiple elastic valve sheets 311, which can save the suction force required during suction.

[0067] In one embodiment, please refer to Figure 7 , along the extension direction of the slit 312 , the size of the slit 312 is smaller than or equal to the size of the deformation portion 31 .

[0068] And there is, in Figure 7 In the example shown, the number of slits 312 is 4, and the number of elastic valve plates 311 is also 4. In some other embodiments, the number of slits 312 and elastic valve plates 311 may be the same or different, and may be other numbers, which can be set according to actual needs.

[0069] In the embodiment of the present application, along the extension direction of the slit 312, the size of the slit 312 is less than or equal to the size of the deformation portion 31. In this way, the multiple elastic valve pieces 311 are separated by the areas cut by the slit 312, and the remaining areas are still connected together. While ensuring that the multiple elastic valve pieces 311 can be opened by the impact of the atomized gas, the elastic valve pieces 311 also have better sealing performance after rebounding due to their own elastic action.

[0070] It can be understood that, along the direction from the first channel 11 to the second channel 21 , when the deformation portion 31 is circular, along the extension direction of the slit 312 , the length of the slit 312 is less than or equal to the diameter length of the deformation portion 31 .

[0071] Alternatively, please refer to Figure 7 , along the direction from the first channel 11 to the second channel 21, when the deformation portion 31 is an ellipse, when the extension direction of the slit 312 is parallel to the major axis of the ellipse, along the extension direction of the slit 312, the length of the slit 312 is less than or equal to the length of the major axis of the deformation portion 31; or, when the extension direction of the slit 312 is parallel to the minor axis of the ellipse, along the extension direction of the slit 312, the length of the slit 312 is less than or equal to the length of the minor axis of the deformation portion 31.

[0072] Of course, the projection profile of the deformation portion 31 along the direction from the first channel 11 to the second channel 21 may also be other shapes, and those skilled in the art may select them according to actual needs, and the embodiments of the present application do not limit this.

[0073] In one embodiment, the thickness of the deformation portion 31 gradually decreases from the edge to the center of the deformation portion 31 .

[0074] In the embodiment of the present application, the thickness of the deformation portion 31, that is, the thickness of the elastic valve sheet 311, gradually decreases from the edge to the center of the deformation portion 31, so that the elastic valve sheet 311 is more easily opened by the impact of the atomizing airflow in the central area of ​​the deformation portion 31, so that the user can absorb the atomized gas without excessive suction force, thereby improving the user experience, and the edge area is not easily deformed when impacted by the atomizing airflow, thereby improving the stability of the deformation portion 31.

[0075] It can be understood that the elastic valve sheet 311 is made of elastic material, and the extension direction along the first channel 11 is the thickness direction of the elastic valve sheet 311, and the thickness of the elastic valve sheet 311 gradually decreases from the edge to the center of the deformation part 31, so that the part of the elastic valve sheet 311 close to the center of the deformation part 31 is more easily deformed and more easily opened by the impact of the atomized airflow.

[0076] In one embodiment, the liquid storage portion 22 may be a cavity, directly accommodating the atomized matrix, or a fiber product, such as a cotton product, may be disposed in the liquid storage portion 22, and the atomized matrix is ​​absorbed and stored in the fiber product.

[0077] In one embodiment, a receiving space 12 is provided in the nozzle 1 , a liquid storage portion 22 is provided in the atomizing assembly 2 , the receiving space 12 is communicated with the liquid storage portion 22 , and the receiving space 12 is used to store the atomizing matrix and provide the atomizing matrix to the liquid storage portion 22 .

[0078] In the embodiment of the present application, a storage space 12 for storing the atomized matrix is ​​provided in the nozzle 1, thereby increasing the storage capacity of the atomized matrix in the electronic atomization device and extending the use time of the electronic atomization device.

[0079] It can be understood that the atomized matrix stored in the liquid storage part 22 of the atomizer assembly 2 is transported to the vicinity of the heating element 24 and then heated and atomized into atomized gas. Since the volume of the atomizer assembly 2 is limited, an additional accommodating space 12 can be provided in the nozzle 1 to increase the storage capacity of the atomized matrix.

[0080] In a specific application, the accommodating space 12 is at least partially arranged around the first channel 11. For example, the accommodating space is only arranged in a ring shape on the left side of the first channel 11, or the accommodating space is only arranged in a ring shape on the right side of the first channel 11, so as to increase the storage capacity of the atomized matrix and utilize the space in the nozzle more flexibly. Alternatively, the accommodating space 12 is completely arranged around the first channel 11, so that the space in the nozzle 1 can be more fully utilized to accommodate as much atomized matrix as possible.

[0081] In some embodiments of the present application, the electronic atomization device further includes a power supply component 4 and a housing 5. The power supply component 4 is electrically connected to the atomization component 2 and is used to provide electrical energy to the atomization component 2. The atomization component 2 and the power supply component 4 are both disposed in the housing 5.

[0082] In a specific application, the atomizer assembly 2 and the power supply assembly 4 may be fixedly connected; or they may be detachably connected, so as to facilitate the user to replace the power supply assembly 4. Those skilled in the art may select according to actual needs, and the embodiments of the present application do not impose any restrictions on this.

[0083] In other embodiments of the present application, the atomization assembly 2 includes a liquid guiding member 23 and a heating member 24.
