[0027] The embodiment of the application discloses an atomization assembly which can be applied to an electronic atomization device for storing atomization liquid and heating the atomization liquid to generate aerosol. The improvement of the atomization assembly of the application is that the liquid injection hole 103 on the atomization shell 100 is a non-circular hole, a liquid injection sealing element 200 with split diaphragm pieces 204 is arranged in the liquid injection hole 103, in the sealed state, the split diaphragm pieces 204 block the liquid injection hole 103, in the liquid injection state, the liquid injection nozzle of the liquid injection bottle abuts against the split diaphragm pieces 204 to deform the split diaphragm pieces 204 to open the liquid injection hole 103, part of the hole wall surface of the liquid injection hole 103 is spaced from the liquid injection nozzle of the liquid injection bottle to form an exhaust passage, the exhaust passage is communicated with the gap between the deformed and adjacent two split diaphragm pieces 204, and is also communicated with the liquid storage cavity 101, so that the liquid injection and exhaust can be realized at the same time through the liquid injection hole 103, without the need to additionally arrange an exhaust hole on the atomization shell 100, which helps to reduce the liquid leakage probability of the atomization assembly.
[0028] Specifically, please refer to Figures 1 to 5The atomization assembly disclosed by the embodiments of the present application comprises an atomization shell 100 and a liquid injection sealing element 200. The atomization shell 100 has a liquid storage cavity 101 for storing atomization liquid. The atomization shell 100 is provided with a liquid injection hole 103 communicating with the liquid storage cavity 101. The atomization assembly has a sealing state of plugging the liquid injection hole 103 and a liquid injection state of opening the liquid injection hole 103 to inject atomization liquid into the liquid storage cavity 101. The liquid injection sealing element 200 is installed on the atomization shell 100 and can plug the liquid injection hole 103 when the atomization assembly is in the sealing state.
[0029] In an embodiment, referring to Figure 2 and Figure 3 , the atomization shell 100 is of a split structure. The atomization shell 100 has a cavity. The atomization assembly comprises an atomization tube 400 located in the atomization shell 100. The atomization tube 400 has an atomization channel 401 and an atomization core (not shown in the figure). The atomization shell 100 is provided with a gas inlet and a gas outlet 104 communicating with the atomization channel 401. The atomization tube 400 is in sealing cooperation with the atomization shell 100 at both ends thereof in the extension direction. Thus, the atomization shell 100 and the atomization tube 400 enclose the liquid storage cavity 101 around the atomization tube 400. The atomization tube 400 is provided with an opening. The atomization liquid in the liquid storage cavity 101 can enter the atomization tube 400 from the opening of the atomization tube 400 and generate aerosol after being heated by the atomization core.
[0030] The liquid injection hole 103 is located at one end of the atomization shell 100 where the gas outlet 104 is located in the extension direction of the atomization channel 401. The extension direction of the liquid injection hole 103 is the same as that of the atomization channel 401. The liquid injection hole 103 is a non-circular hole, i.e., any cross-sectional shape of the liquid injection hole 103 perpendicular to the extension direction thereof is not circular. The cross-sectional shape of the liquid injection nozzle of a liquid injection bottle for injecting liquid into the liquid storage cavity 101 is mostly circular. Thus, in the process of inserting the liquid injection nozzle of the liquid injection bottle into the liquid injection hole 103 for liquid injection, part of the hole wall surface of the liquid injection hole 103 will be in contact with the liquid injection nozzle of the liquid injection bottle, and the other part of the hole wall surface will be spaced apart from the liquid injection nozzle of the liquid injection bottle. Thus, an exhaust channel communicating with the liquid storage cavity 101 will be formed between the hole wall surface of the liquid injection hole 103 and the outer peripheral surface of the liquid injection nozzle of the liquid injection bottle. In the process of injecting liquid into the liquid storage cavity 101, the excess gas in the liquid storage cavity 101 will be discharged along the exhaust channel to achieve the pressure balance inside and outside the liquid storage cavity 101. On the one hand, it is convenient for the liquid injection bottle to continue to inject liquid into the liquid storage cavity 101. On the other hand, the liquid injection and exhaust are simultaneously achieved through the liquid injection hole 103, which helps to simplify the structure of the entire atomization assembly, avoid setting an exhaust hole on the atomization shell 100, and reduce the probability of liquid leakage of the atomization assembly.
[0031] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5, the hole wall surface of the liquid injection hole 103 comprises an outer convex surface 1031, the outer convex surface 1031 protrudes away from the liquid injection hole 103 in a plane perpendicular to the extending direction of the liquid injection hole 103, such as protruding away from the geometric center of the liquid injection hole 103, the geometric center can be understood as: when the cross-sectional shape of the liquid injection hole 103 is square, the geometric center of the liquid injection hole 103 is the intersection of the square diagonal lines; when the cross-sectional shape of the liquid injection hole 103 is triangular, the geometric center of the liquid injection hole 103 is the intersection of the three centers of the triangle; when the cross-sectional shape of the liquid injection hole 103 is trapezoidal, the geometric center of the liquid injection hole 103 is the intersection of the trapezoidal diagonal lines; or in other embodiments, the outer convex surface 1031 can also protrude away from the symmetry axis or symmetry center of the liquid injection hole 103. The outer convex surface 1031 can comprise a curved surface, an arc surface, or can also comprise a plurality of flat surfaces. During the process of inserting the liquid injection nozzle of the liquid injection bottle into the liquid injection hole 103 for liquid injection, the outer convex surface 1031 of the liquid injection hole 103 can be arranged spaced apart from the liquid injection nozzle, and the hole wall surface of the liquid injection hole 103 and the outer peripheral surface of the liquid injection nozzle can enclose a gas exhaust passage at the position of the outer convex surface 1031, which communicates with the liquid storage cavity 101. The gas in the liquid storage cavity 101 can be exhausted from the gas exhaust passage during the liquid injection process.
[0032] In an embodiment, the outer convex surface 1031 on the hole wall surface of the liquid injection hole 103 has several, such as one, two, or more than three. In the embodiment of multiple outer convex surfaces 1031, two adjacent outer convex surfaces 1031 are arranged spaced apart in the circumferential direction around the liquid injection hole 103, so as to form multiple gas exhaust passages in the circumferential direction around the liquid injection nozzle during the process of injecting liquid into the liquid storage cavity 101 by the liquid injection bottle, which helps to achieve uniform gas exhaust of the liquid storage cavity 101 in the circumferential direction around the liquid injection nozzle.
[0033] In some embodiments, the hole wall surface of the liquid injection hole 103 comprises a flat surface to facilitate the processing of the liquid injection hole 103, and the flat surface can be located between two adjacent outer convex surfaces 1031 in the circumferential direction around the liquid injection hole 103. For example, in an embodiment, please continue to refer to Figure 1 、 Figure 4 and Figure 5, the cross-sectional shape of the liquid injection hole 103 is generally rectangular, the hole wall surface of the liquid injection hole 103 includes a first flat surface 1032 corresponding to the long side of the rectangle and a second flat surface 1033 corresponding to the wide side of the rectangle, the first flat surface 1032 is perpendicular to the second flat surface 1033, the outer convex surface 1031 is located between the first flat surface 1032 and the second flat surface 1033, the outer convex surface 1031 can be an arc surface or a curved surface, the outer convex surface 1031 is arranged protruding away from the liquid injection hole 103 in the length direction of the rectangular shape of the liquid injection hole 103, the outer convex surface 1031 is smoothly connected to each flat surface, the outer convex surface 1031 can be tangent to the first flat surface 1032, and the outer convex surface 1031 can also be connected to the second flat surface 1033 through an arc surface or a curved surface. When the atomization assembly is in the liquid injection state, the outer peripheral surface of the liquid injection nozzle of the liquid injection bottle can be attached to the first flat surface 1032 and / or the second flat surface 1033, and the outer convex surface 1031 is arranged in spaced apart relation to the outer peripheral surface of the liquid injection nozzle, so that the hole wall surface of the liquid injection hole 103 and the liquid injection nozzle together form an exhaust passage located at the position of the outer convex surface 1031.
[0034] In an embodiment, the second flat surface 1033 is replaced by a circular arc surface, which can be attached to the outer peripheral surface of the liquid injection nozzle on the liquid injection bottle during the liquid injection process, thereby positioning the liquid injection nozzle of the liquid injection bottle during liquid injection, facilitating liquid injection while freeing the hands, and achieving automatic liquid injection.
[0035] In other embodiments, the hole wall surface of the liquid injection hole 103 can also not include flat surfaces, such as an embodiment in which the cross-sectional shape of the liquid injection hole 103 is elliptical, the hole wall surfaces corresponding to the two ends of the major axis of the ellipse can be used as the outer convex surface 1031, when the atomization assembly is in the liquid injection state, the liquid injection nozzle is attached to the hole wall surfaces at the two ends of the minor axis of the elliptical liquid injection hole, and the hole wall surface of the entire liquid injection hole 103 and the outer peripheral surface of the liquid injection nozzle together form an exhaust passage at the two ends of the major axis of the ellipse. In another embodiment, the cross-sectional shape of the liquid injection hole 103 can also be rhombus-shaped, the hole wall surface of the liquid injection hole 103 is composed of flat surfaces, and the hole wall surfaces corresponding to the four corners of the rhombus can be used as the outer convex surface 1031.
[0036] In some embodiments, in any plane perpendicular to the extension direction of the liquid injection hole 103, the cross-sectional shape of the liquid injection hole 103 is an axisymmetric structure or can also be a central symmetric structure, such as the above-mentioned embodiments in which the cross-sectional shape of the liquid injection hole 103 can be generally rectangular, elliptical or rhombus-shaped. In embodiments in which the cross-sectional shape of the liquid injection hole 103 is axisymmetric or central symmetric, the exhaust passage located at the outer convex surface 1031 can be central symmetric about the liquid injection nozzle on the liquid injection bottle or symmetrically arranged on both sides of the liquid injection nozzle when the atomization assembly is in the liquid injection state, which helps to make the exhaust of the liquid storage cavity 101 uniform during liquid injection.
[0037] Of course, in other embodiments, the cross-sectional shape of the liquid injection hole 103 can be a non-axially symmetric or non-centrally symmetric special-shaped structure, as long as the exhaust passages located at the outer convex surface 1031 are arranged at intervals in the circumferential direction around the liquid injection nozzle when the atomization assembly is in the liquid injection state.
[0038] In the atomization assembly of the embodiments of the present application, the liquid injection sealing member 200 is mounted on the atomization shell 100, and the liquid injection sealing member 200 can be located on the side of the liquid injection hole 103 away from the liquid storage cavity 101 or on the side of the liquid injection hole 103 facing the liquid storage cavity 101 in the extension direction of the liquid injection hole 103. The liquid injection sealing member 200 has a plurality of split diaphragms 204, which block the liquid injection hole 103 when the atomization assembly is in the sealed state. When the atomization assembly is in the liquid injection state, under the abutting action of the liquid injection nozzle on the liquid injection bottle, the plurality of split diaphragms 204 deform towards the liquid storage cavity 101 to open the liquid injection hole 103, and the end of the liquid injection nozzle can pass through the split diaphragm 204 and extend to the side of the split diaphragm 204 facing the liquid storage cavity 101 to realize liquid injection into the liquid storage cavity 101. In this way, the probability of atomization liquid remaining on the side of the split diaphragm 204 away from the liquid storage cavity 101 can be reduced. Under the abutting action of the liquid injection nozzle on the liquid injection bottle, a gap will be formed between two adjacent split diaphragms 204, which can communicate with the exhaust passages between the hole wall surface of the liquid injection hole 103 and the outer peripheral surface of the liquid injection nozzle to realize exhaust of the liquid storage cavity 101.
[0039] In an embodiment, the atomization shell 100 has an outer end surface 102 at one end in the extension direction of the atomization channel 401, and the gas outlet 104 and the liquid injection hole 103 are both located on the outer end surface 102. The atomization shell 100 has a first hole end surface facing the liquid storage cavity 101 and a second hole end surface away from the liquid storage cavity 101 in the extension direction of the liquid injection hole 103 at the liquid injection hole 103. The split diaphragm 204 can be press-fitted and fixed on the first hole end surface or the second hole end surface to realize the installation of the liquid injection sealing member 200 on the atomization shell 100.
[0040] In an embodiment, please refer to Figure 2 , Figure 3 and Figure 5, the atomization shell 100 has a sink groove 105, the sink groove 105 has a groove opening which is oriented in the same direction as the extending direction of the liquid injection hole 103, the sink groove 105 has a groove opening which is oriented towards the liquid storage cavity 101, the cross-sectional shape of the sink groove 105 can be circular, or can also be square, other special shapes, etc., the liquid injection hole 103 is located on the groove bottom wall of the sink groove 105, the liquid injection sealing element 200 is located on the side of the liquid injection hole 103 which is oriented towards the liquid storage cavity 101, the liquid injection sealing element 200 is located in the sink groove 105, the second hole end surface is coplanar with the outer end surface 102, which on the one hand helps to ensure the flatness of the outer end surface 102 of the atomization shell 100, facilitates the subsequent sealing of the liquid injection hole 103 by the suction nozzle sealing part 503, helps to reduce the sealing area of the suction nozzle sealing part 503 to the liquid injection hole 103, and on the other hand the cross-sectional dimension of the sink groove 105 is greater than the cross-sectional dimension of the liquid injection hole 103, which facilitates the direct insertion of the liquid injection nozzle into the liquid injection hole 103 for liquid injection, and facilitates the cleaning of the residual atomization liquid on the hole wall surface of the liquid injection hole 103.
[0041] In the process of liquid injection, the liquid injection nozzle is first inserted into the liquid injection hole 103, and after passing through the liquid injection hole 103, it abuts against the split diaphragm 204 and makes the end of the liquid injection nozzle pass over the split diaphragm 204 to achieve liquid injection. In another embodiment, the groove opening of the sink groove 105 can also be oriented away from the liquid storage cavity 101, the sink groove 105 is located on the side of the liquid injection hole 103 which is oriented away from the liquid storage cavity 101, the second hole end surface is coplanar with the groove bottom surface of the sink groove 105, and during liquid injection, the end of the liquid injection nozzle is first inserted into the sink groove 105, abuts against the split diaphragm 204 and passes over the split diaphragm 204 and is inserted into the liquid injection hole 103 to achieve liquid injection.

Of course, in other embodiments, the split diaphragm 204 can also be connected to the middle position of the mounting ring 201 with the slot opening of the sink 105 facing upward, or connected to the end of the mounting ring 201 facing the liquid storage cavity 101.
[0045] In an embodiment, please continue to refer to Figures 1 to 3 , the atomization assembly includes a compression ring 300 made of a metal material, and the liquid injection sealing element 200 is made of a rubber material as a whole. The compression ring 300 is riveted in the sink 105, and the liquid injection sealing element 200 is press-fitted and fixed between the compression ring 300 and the groove bottom wall of the sink 105, so as to realize the installation and fixation of the liquid injection sealing element 200 in the sink 105.
[0046] In an embodiment, please refer to Figure 1 , the liquid injection sealing element 200 has a mounting ring 201 and a center diaphragm 202 connected in the mounting ring 201. In the extension direction of the liquid injection hole 103, the size of the mounting ring 201 is greater than that of the center diaphragm 202, and the radial thickness of the mounting ring 201 is greater than the thickness of the center diaphragm 202. The center diaphragm 202 has a cutout 203, and the center diaphragm 202 includes split diaphragms 204 on both sides of the cutout 203. In this way, by providing the cutout 203 to form a plurality of split diaphragms 204 in the mounting ring 201, the processing and manufacturing of the entire liquid injection sealing element 200 are facilitated.

During the installation of the liquid injection seal 200, the split diaphragm 204 can be bent radially inward of the mounting ring 201, and then the entire liquid injection seal 200 is press-fitted and fixed in the sink 105, so that the plurality of split diaphragms 204 are stacked to block the sealed liquid injection hole 103 when the atomization assembly is in a sealed state.
[0049] In the atomization assembly of the embodiments of the present application, please refer to Figure 2 When the atomization assembly is in a sealed state, the plurality of split diaphragms 204 can automatically close to block the liquid injection hole 103 without external force, thereby preventing the atomization liquid from leaking along the liquid injection hole 103. Please refer to Figure 3 When the atomization assembly is in a liquid injection state, the liquid injection nozzle of the liquid injection bottle abuts the split diaphragm 204 from the outside to the inside, so that each split diaphragm 204 bends and deforms inwardly of the liquid storage cavity 101. In this way, a gap is formed between the adjacent two split diaphragms 204, which is in communication with the exhaust passage. The liquid injection nozzle can extend into the liquid storage cavity 101 from the center of the center diaphragm 202, that is, from the intersection position of each split diaphragm 204, to realize liquid injection into the liquid storage cavity 101. After the liquid injection is completed, the liquid injection nozzle is pulled out, and each split diaphragm 204 can reset to abut to block the liquid injection hole 103 under the action of elastic deformation.
[0050] In some embodiments, please refer to Figures 1 to 3 The atomization assembly further includes a suction nozzle piece 500, which is detachably mounted on the atomization shell 100. The suction nozzle piece 500 includes a suction nozzle shell 501 and a suction nozzle sealing part 503 located in the suction nozzle shell 501. The suction nozzle sealing part 503 can be made of rubber material. The suction nozzle shell 501 can be detachably connected to the atomization shell 100 through a buckle structure. The suction nozzle shell 501 has a suction nozzle passage 502. After the suction nozzle shell 501 is connected to the atomization shell 100, the suction nozzle shell 501 is located on one side of the atomization shell 100 in the direction of the atomization passage 401. The suction nozzle passage 502 of the suction nozzle shell 501 is in communication with the gas outlet 104 of the atomization shell 100. The suction nozzle sealing part 503 is press-fitted and fixed between the suction nozzle shell 501 and the atomization shell 100, and abuts the outer end surface 102 of the atomization shell 100 in the direction of the atomization passage 401, so as to block the liquid injection hole 103 on the outer end surface 102 of the atomization shell 100 through the suction nozzle sealing part 503. In this way, the atomization liquid in the liquid storage cavity 101 can be prevented from leaking from the liquid injection hole 103, and the probability of liquid leakage of the atomization assembly can be greatly reduced.
[0051] In other embodiments, in the embodiment in which the diaphragm 204 is relatively hard, the inverted atomization assembly causes the atomization liquid in the liquid storage cavity 101 to be on the upper side of the diaphragm 204, and the diaphragm 204 will not be deformed under the pressure of the atomization liquid, in which case, the setting of the suction nozzle sealing portion 503 in the suction nozzle piece 500 can be cancelled, and only the liquid injection hole 103 is blocked by the diaphragm 204, so as to reduce the liquid leakage probability of the atomization assembly.
[0052] The application further discloses an electronic atomization device, which comprises a power supply assembly and the atomization assembly in any of the above embodiments.

According to the idea of the utility model, those skilled in the art of the utility model can make some simple deductions, deformations or substitutions.
