DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The present application provides an atomization device. In one embodiment, referring to Figures 1 to 3 , Figure 1 is a three-dimensional schematic diagram of an exemplary embodiment of the atomization device provided by the present application, Figure 2 yes Figure 1 , the atomizing device 100 includes a housing assembly 110, a first sealing member 120 and a liquid storage member 130. The housing assembly 110 is formed with a receiving chamber 110a, and the housing assembly 110 is provided with a first opening 101 communicating with the receiving chamber 110a. The first sealing member 120 is sealed in the first opening 101, and the first sealing member 120 is provided with an air outlet 123. The liquid storage member 130 is located in the receiving chamber 110a, and the liquid storage member 130 is used to absorb the atomized liquid. Figure 3 yes Figure 2 The present invention is a three-dimensional schematic diagram of the first sealing member 120 in the atomization device 100, wherein the first sealing member 120 has a first surface 120a facing the liquid storage member 130, and the first sealing member 120 includes a plurality of mutually spaced support portions 121 protruding from the first surface 120a, and the support portions 121 abut against the liquid storage member 130, so that a gap 122 is formed between the first surface 120a of the liquid storage member 130 and the first sealing member 120.

[0030] The liquid storage member 130 may be a porous structure with dense pores inside, such as oil storage cotton. After the liquid storage member 130 absorbs the atomized liquid, the atomized liquid may be stored in the pores inside the liquid storage member 130 .

[0031] The material of the first sealant can be silicone or other elastic materials.

[0032] It can be seen that the atomized liquid in the liquid storage member 130 forms an aerosol after atomization and enters the first opening 101 through the air outlet 123. The present application provides a support portion 121 on the first surface 120a of the first sealing member 120 facing the liquid storage member 130, so that a gap 122 can be formed between the first surface 120a of the first sealing member 120 and the first sealing member 120. Since the liquid storage member 130 needs to be injected with atomized liquid when it is assembled into the accommodating cavity 110a, the liquid storage member 130 will expand after being injected with the atomized liquid, and the liquid storage member 130 will expand when the atomized liquid is injected. It will also expand after being heated, and its volume will increase. If the first sealing component 120 is directly and completely fitted with the liquid storage component 130, there will be no deformation space for the liquid storage component 130, and the liquid storage component 130 will be squeezed by the inner wall of the shell assembly 110 to cause leakage. In the present application, a gap 122 is formed between the first surface 120a of the first sealing component 120 and the first sealing component 120 through the support portion 121 on the first sealing component 120. The gap 122 reserves a certain space for the deformation of the liquid storage component 130, so as to avoid leakage caused by deformation of the liquid storage component 130 after the atomized liquid is injected.

[0033] In one embodiment, the air outlet 123 on the first sealing member 120 is spaced a certain distance from the support portion 121 in a direction perpendicular to the axial direction of the air outlet 123, so the support portion 121 does not affect the ventilation of the air outlet 123. Of course, the present application does not exclude the situation where the air outlet 123 is directly disposed on the support portion 121.

[0034] See again Figure 2 , and also see Figure 4 , Figure 4 yes Figure 3 The third embodiment is a three-dimensional schematic diagram of the first sealing member from another perspective. In one embodiment, the atomizing device 100 further includes a liquid absorbent member 140. The first sealing member 120 further includes a second surface 120b opposite to the first surface 120a. The second surface 120b is recessed to form a groove 124. The liquid absorbent member 140 is accommodated in the groove 124. The liquid absorbent member 140 can absorb the condensed liquid of the aerosol to prevent the condensed liquid from being directly sucked into the human mouth through the first opening 101 to affect the suction taste. The liquid absorbent member 140 can be a component with a certain liquid absorption capacity such as liquid absorbent cotton. The groove 124 is a component for accommodating the liquid absorbent member 140. The groove 124 can receive the liquid overflowed from the liquid absorbent member 140 to prevent the liquid overflowed from the liquid absorbent member 140 from flowing out. At the same time, the liquid absorbent member 140 in the groove 124 can absorb the condensed liquid of the aerosol.

[0035] See again Figure 4In one embodiment, the groove bottom of the groove 124 is concave to form a groove-shaped recessed portion 125, the groove top of the groove-shaped recessed portion 125 is in contact with the liquid absorbing member 140, and the groove-shaped recessed portion 125 includes a plurality of grooves connected in a tree shape. In this embodiment, the groove 124 further forms a groove-shaped recessed portion 125 composed of a plurality of grooves connected in a tree shape, and the groove top of the groove-shaped recessed portion 125 is in contact with the liquid absorbing member 140, so that the liquid overflowing from the liquid absorbing member 140 can fall into the groove-shaped recessed portion 125 for storage, thereby increasing the liquid absorbing capacity of the liquid absorbing member 140. In addition, the groove-shaped recessed portion 125 can be connected to the air outlet 123, so that the liquid stored in the groove-shaped recessed portion 125 can flow back into the liquid storage member 130 through the air outlet 123.

[0036] Continue reading Figure 4 In one embodiment, the plurality of grooves include a plurality of first grooves 126 and at least one second groove 127 , the plurality of first grooves 126 are spaced apart from each other and arranged in parallel, and the second groove 127 intersects the plurality of first grooves 126 at right angles. Figure 4 The case where the number of the first groove portions 126 is five and the number of the second groove portion 127 is one is shown.

[0037] Continue reading Figure 4 In one embodiment, the bottom of the groove 124 includes a flat portion 128 and a protruding portion 129, the protruding portion 129 protrudes from the flat portion 128, and the groove-shaped recessed portion 125 is disposed on the protruding portion 129 so that the protruding portion 129 forms a plurality of convex ribs. In this embodiment, the groove-shaped recessed portion 125 can not only store the condensate, but also form a plurality of convex ribs on the protruding portion 129, which can function as reinforcing ribs, thereby increasing the structural strength of the bottom of the groove 124, that is, increasing the structural strength of the first sealing member 120.

[0038] See again Figure 2 , and also see Figure 5 , Figure 5 yes Figure 4In one embodiment, the atomizing device 100 further includes an atomizing element 180, the liquid storage element 130 is covered on the atomizing element 180, an atomizing channel 181 is provided in the atomizing element 180, and the air outlet 123 is arranged opposite to the atomizing channel 181. A ventilation gap 182 is formed between the end surface of the atomizing element 180 and the first sealing element 120. The atomizing element 180 is used to heat the atomized liquid infiltrated into the liquid storage element 130, generate aerosol and enter the air outlet 123 of the first sealing element 120 through the atomizing channel 181. In this embodiment, due to the existence of the ventilation gap 182, a part of the aerosol generated by the atomizer 180 can directly enter the air outlet 123 of the first sealing component 120 through the atomization channel 181, and the other part enters the gap 122, and then enters the air outlet 123 of the first sealing component 120 through the gap 122. It is precisely because the aerosol generated by the atomizer 180 can enter the gap 122 that the pressure in the accommodating chamber 110a can be relieved, thereby preventing the pressure in the accommodating chamber 110a from increasing and causing leakage of the atomized liquid.

[0039] It is understandable that in other embodiments, the ventilation gap 182 may not be set between the atomizer 180 and the first seal 120, but the atomizer 180 and the first seal 120 are directly connected. In these embodiments, the gap 122 formed between the first seal 120 and the liquid storage member 130 only serves as a space for the liquid storage member 130 to expand and deform, and the aerosol generated by the atomizer 180 directly enters the air outlet 123 of the first seal 120 only through the atomization channel 181.

[0040] One end of the atomizer 180 facing the first sealing member 120 may protrude from one side of the liquid storage member 130 facing the first sealing member 120 to prevent the atomized liquid in the liquid storage member 130 from entering the atomization channel 181 of the atomizer 180 through the end of the atomizer 180 facing the first sealing member 120 .

[0041] In one embodiment, the air outlet 123 includes an air inlet expansion section 1231, the inner diameter of the air inlet expansion section 1231 facing the atomizer 180 is greater than the inner diameter of the air inlet expansion section 1231 facing away from the atomizer 180, and the inner diameter of the air inlet expansion section 1231 gradually decreases from the air inlet expansion section 1231 facing the atomizer 180 to the direction away from the atomizer 180. In this embodiment, the air inlet expansion section 1231 is provided to facilitate the gas in the gap 122 and the atomization channel 181 of the atomizer 180 to enter the air outlet 123 through the air inlet expansion 1231.

[0042] In one embodiment, the atomizing device 100 further includes a nozzle 170, in which an air outlet channel 171 is provided, and the air outlet channel 171 is connected to the first opening 101, and the nozzle 170 is used for suction by the human mouth. The nozzle 170 is connected to the housing assembly 110, and the nozzle 170 is located on the side of the first opening 101 away from the first sealing member 120. The nozzle 170 can be integrally formed with the housing assembly 110, or it can be separately provided with the housing assembly 110. The inner diameter of the air inlet expansion section 1231 facing the side of the nozzle 170 is the same as the inner diameter of the air outlet channel 171, and the orthographic projection of the atomizing channel 181 in the axial direction is located in the air inlet expansion section 1231. In this embodiment, the air inlet expansion section 1231 facilitates collecting the gas in the atomization channel 181 of the atomizer 180, so that the gas in the atomization channel 181 of the atomizer 180 can quickly and sufficiently enter the air outlet channel 171 of the first sealing component 120 through the air inlet expansion section 1231.

[0043] See again Figure 2 , and also see Figure 6 , Figure 6 yes Figure 2 The axial cross-sectional view of the shell assembly in the atomization device of the present invention is shown in FIG. 1 . In one embodiment, the shell assembly 110 includes an inner shell 111, a middle shell 112 and an outer shell 113 which are sequentially sleeved from the inside to the outside. The middle shell 112 is located in the outer shell 113, and one end of the middle shell 112 forms a first opening 101. The outer shell 113 extends from one end corresponding to the first opening 101 to form a suction nozzle 170, which is connected to the first opening 101, and the suction nozzle 170 is used for suction by the human mouth. The inner shell 111 is located in the middle shell 112, and one end of the inner shell 111 is spaced from the first opening 101. The first sealing member 120 is sealed to the inner wall of the middle shell 112, and the first sealing member 120 is sealed to one end of the inner shell 111 facing the first opening 101. It can be understood that in other embodiments, the shell assembly 110 can also adopt a single-layer or double-layer or other number of layers of shell structure.

[0044] Specifically, in this embodiment, the suction nozzle 170 can be integrally formed with the shell 113, or can be separately provided with the shell 113. The suction nozzle 170 can be a double-layer shell structure, the outer shell of the suction nozzle 170 is connected to the shell 113, and the inner shell of the suction nozzle 170 forms an air outlet channel 171, and the air outlet channel 171 is connected to the air outlet hole 123 of the first sealing member 120. To achieve better assembly and sealing effects, the inner shell of the suction nozzle 170 can be inserted into the first opening 101 formed in the middle shell 112, and the inner shell of the suction nozzle 170 and the first opening 101 are sealed by a sealing ring to prevent leakage of the atomized liquid.

[0045] In one embodiment, the atomizing device 100 further includes a blocking member 150, which is used to block the air outlet channel 171. When the atomizing device 100 is not in use, the blocking member 150 can be blocked in the air outlet channel 171 to prevent the atomized liquid in the liquid storage member 130 from leaking out through the air outlet channel 171 of the suction nozzle 170. At the same time, in order to play a dust-proof role, the atomized liquid in the liquid storage member 130 can also be prevented from volatilizing.

[0046] In one embodiment, the end surface of the middle shell 112 corresponding to the first opening 101 is further provided with a mounting protruding ring 1121 facing the liquid storage member 130, and the mounting protruding ring 1121 is inserted into the groove 124 on the first sealing member 120. The mounting protruding ring 1121 is spaced apart from the side wall of the middle shell 112 to form a mounting concave ring, and the first sealing member 120 is tightly inserted into the mounting concave ring to achieve fixed installation of the first sealing member 120, and in order to further achieve the fixation of the first sealing member 120 in the mounting concave ring, one or more circles of protrusions can be provided on the outer wall of the first sealing member 120 and the groove wall of the groove 124 to increase the fixing effect of the first sealing member 120. The liquid absorbing member 140 is tightly inserted into the inner side of the mounting concave ring to achieve fixed installation of the liquid absorbing member 140 in the groove 124 on the first sealing member 120. Of course, in other embodiments, the liquid absorbing member 140 can also be directly fixed in the groove 124 on the first sealing member 120.

[0047] The housing 113 may be made of a transparent material such as transparent plastic to provide a decorative effect.

[0048] See again Figure 2 In one embodiment, the atomizing device 100 further includes a second sealing member 160 and a bottom cover 190. The housing assembly 110 further includes a second opening 102 communicating with the accommodating chamber 110a. The first opening 101 and the second opening 102 are respectively located at two ends of the housing assembly 110. The second sealing member 160 covers the second opening 102. The liquid storage member 130 is sandwiched between the first sealing member 120 and the second sealing member 160. The bottom cover 190 is located on the side of the second sealing member 160 away from the liquid storage member 130. The second sealing member 160 is used to prevent the atomized liquid from leaking from the second opening 102. The bottom cover 190 can be fixed to the housing assembly 110 in a snap-fit ​​manner, but is not limited to.
