[0028] Current atomizing devices usually adopt an integral structure design, that is, the atomizer 100 and the liquid storage container 200 are integrated into one and cannot be easily disassembled. With the continuous improvement of usage requirements, some atomizing devices also design the connection between the liquid storage container 200 and the atomizer 100 as a magnetic detachable form for the convenience of replenishing the atomization matrix. However, the liquid storage container 200 installed magnetically has a risk of falling during use.

[0029] In the embodiment of the present application, by providing the anti - detachment protrusion 122 and the anti - detachment groove 210, it helps to enhance the connection stability and safety between the liquid storage container 200 and the atomizer 100. Not only can the liquid storage container 200 be conveniently disassembled, but also the risk of the liquid storage container 200 falling during use can be reduced.

[0030] An atomizing device is disclosed in an embodiment. Please refer to Figures 1 - 5 , the atomizing device includes an atomizer 100 and a liquid storage container 200.

[0031] The atomizer 100 can be understood as a collection of the basic structural framework, the outer contour form, and the related components that realize the atomization function of the atomizing device. With the help of the atomizer 100, the atomizing device can be held, moved, operated, and used.

[0032] In one embodiment, please refer to Figures 1 - 3 , the atomizer 100 has an atomization chamber 130, an installation chamber 120, and a liquid storage chamber 110. The atomization chamber 130 and the installation chamber 120 are arranged side by side. An installation opening 121 is provided on the installation chamber 120. The atomization chamber 130 includes a mouthpiece 131 that communicates with the atomization chamber 130. The installation opening 121 and the mouthpiece 131 are provided at the same end of the atomizer 100. The atomization chamber 130 and the installation chamber 120 are connected through the liquid storage chamber 110.

[0033] Exemplarily, the atomizer 100 is a long - strip - shaped structure with a length direction. A mouthpiece 131 is provided at one end of the atomizer 100 along the length direction. The atomization chamber 130 and the installation chamber 120 are arranged side by side on the side of the atomizer 100 where the mouthpiece 131 is provided. The mouthpiece 131 communicates with the atomization chamber 130. An installation opening 121 is provided on the installation chamber 120. The installation opening 121 is arranged side by side with the mouthpiece 131. The liquid storage chamber 110 is arranged at the end of the installation chamber 120 away from the installation opening 121 and the end of the atomization chamber 130 away from the mouthpiece 131. The liquid storage chamber 110 is respectively connected to the installation chamber 120 and the atomization chamber 130. A liquid storage member 111 can be arranged in the liquid storage chamber 110. The liquid storage member 111 can be a liquid storage cotton, a liquid storage block, a liquid storage fiber, or other elements that can store the liquid atomization matrix.

[0034] The liquid storage container 200 is used to store the liquid atomization matrix, and can be a liquid storage bottle, a liquid storage tube or other containers capable of storing liquid. In one embodiment, the liquid storage container 200 is inserted into the installation cavity 120 through the installation port 121 for supplying liquid to the liquid storage cavity 110. Exemplarily, please refer to Figure 2 , on the cavity wall between the installation cavity 120 and the liquid storage cavity 110 of the atomizer 100, there is a liquid outlet through hole 140. The liquid storage container 200 has a container opening 221. When the liquid storage container 200 is inserted into the installation cavity 120, the container opening 221 is inserted into the liquid outlet through hole 140.

[0035] In order to improve the connection stability and safety between the liquid storage container 200 and the atomizer 100, so that the liquid storage container 200 can be conveniently disassembled and the falling risk during use can be reduced. In one embodiment, please refer to Figures 2 - 4 , on one of the cavity wall of the installation cavity 120 and the peripheral wall of the liquid storage container 200, there is an anti-detachment protrusion 122, and on the other, there is an anti-detachment groove 210 matching the anti-detachment protrusion 122. When the liquid storage container 200 is installed in the installation cavity 120, the anti-detachment protrusion 122 is clamped in the anti-detachment groove 210.

[0036] Exemplarily, please refer to Figures 2 - 4 , on the middle part of the cavity wall of the installation cavity 120 near the mouthpiece 131 and biased towards the installation port 121, there is an anti-detachment protrusion 122, and on the corresponding peripheral wall of the liquid storage container 200, there is an anti-detachment groove 210. In some embodiments, the setting direction of the anti-detachment protrusion 122 and the anti-detachment groove 210 intersects with the insertion direction of the liquid storage container 200 into the installation cavity 120. For example, the setting direction of the anti-detachment protrusion 122 and the anti-detachment groove 210 is perpendicular to the insertion direction of the liquid storage container 200 into the installation cavity 120.

[0037] In other embodiments, the anti-detachment groove 210 can also be provided on the cavity wall of the installation cavity 120, and the anti-detachment protrusion 122 can be provided on the peripheral wall of the liquid storage container 200; or, both the cavity wall of the installation cavity 120 and the peripheral wall of the liquid storage container 200 are provided with anti-detachment grooves 210 and anti-detachment protrusions 122, as long as the anti-detachment grooves 210 and anti-detachment protrusions 122 on the cavity wall of the installation cavity 120 and the peripheral wall of the liquid storage container 200 can be adapted. In addition, the positions, directions and numbers of the anti-detachment grooves 210 and anti-detachment protrusions 122 can be adjusted according to needs, and those that can meet the design purpose and use requirements are all acceptable.

[0038] In one embodiment, please refer to Figure 3, the anti - detachment protrusion 122 has arc - shaped surfaces 1221 on both sides along the insertion and extraction direction of the liquid storage container 200, so that the liquid storage container 200 can be inserted into or extracted from the installation cavity 120. In other embodiments, the surfaces on both sides of the anti - detachment protrusion 122 along the insertion and extraction direction of the liquid storage container 200 can also be set as wedge - shaped surfaces, or only one of the two side surfaces can be set as the arc - shaped surface 1221 or the wedge - shaped surface according to needs.

[0039] In one embodiment, in order to further improve the connection stability and safety between the liquid storage container 200 and the atomizer 100, please refer to Figure 2 , a sealing sleeve 141 is embedded in the liquid outlet through - hole 140. When the liquid storage container 200 is inserted into the installation cavity 120, the container opening 221 is inserted into the sealing sleeve 141 and is in interference fit with the sealing sleeve 141.

[0040] Exemplarily, please refer to Figure 2 , a ring - shaped rib 142 is provided on the inner wall of the liquid outlet through - hole 140, and a ring groove 1411 for engaging with the ring - shaped rib 142 is provided on the outer peripheral wall of the sealing sleeve 141. When the sealing sleeve 141 is embedded in the liquid outlet through - hole 140, the ring - shaped rib 142 is embedded in the ring groove 1411 to position and fix the sealing sleeve 141.

[0041] In some embodiments, please refer to Figure 2 , there are at least two annular protrusions 1412 along the axial direction of the sealing sleeve 141 on the inner wall of the sealing sleeve 141. When the container opening 221 is inserted into the sealing sleeve 141, at least part of the annular protrusions 1412 abuts against the outer peripheral wall of the container opening 221 to form a multi - stage clamping structure, improving the connection stability and sealing performance.

[0042] Since when replacing the liquid storage container 200, the liquid storage container 200 is usually inserted into the installation cavity 120 in an inverted manner. "Inverted insertion" means that with the Figure 2 shown perspective, the installation opening 121 of the installation cavity 120 is facing upwards, and the container opening 221 of the liquid storage container 200 is inserted into the installation cavity 120 with the container opening 221 facing downwards. Inserting the container opening 221 of the liquid storage container 200 downwards easily causes liquid leakage during the insertion process. In one embodiment, in order to solve this problem, a sealing valve 240 for closing the container opening 221 is provided in the liquid storage container 200; a push rod 112 is provided in the liquid storage cavity 110. The push rod 112 is arranged opposite to the liquid outlet through - hole 140, and one end of the push rod 112 is inserted into the installation cavity 120 through the liquid outlet through - hole 140. When the container opening 221 of the liquid storage container 200 is inserted into the liquid outlet through - hole 140, the push rod 112 pushes the sealing valve 240 to the open state, so that the container opening 221 of the liquid storage container 200 is communicated with the inner cavity of the liquid storage cavity 110.

[0043] The setting of the sealing valve 240 enables the container opening 221 of the liquid storage container 200 to be in a closed state before being inserted by the ejector rod 112, which helps to avoid liquid leakage during the installation of the liquid storage container 200.

[0044] Exemplarily, please refer to Figure 2 and Figure 5 , the liquid storage container 200 includes a container main body 230 and a container cover 220. The container cover 220 is covered and assembled on the container main body 230. The container opening 221 is provided on the side of the container cover 220 facing away from the container main body 230. The sealing valve 240 is provided on the side of the container cover 220 close to the container main body 230. The sealing valve 240 includes a valve body 241, a valve core 242 and an elastic member 243. The valve body 241 is fixedly provided on the container cover 220. The valve core 242 is arranged to move axially along the container opening 221 opposite to the container opening 221 on the valve body 241. A plug 2421 capable of inserting into the container opening 221 to block the container opening 221 is provided at one end of the valve core 242 close to the container opening 221. A sealing ring 2422 is sleeved on the plug 2421. The elastic member 243 is arranged between the valve core 242 and the valve body 241 for applying an elastic force to the valve core 242 to move in the direction close to the container opening 221. The elastic member 243 can be a spring, an elastic rubber pad, a reed or other elastic structural members capable of generating an elastic force meeting the design requirements.

[0045] In some embodiments, the ejector rod 112 can be configured to be in contact with the valve core 242 only when it continues to be inserted after the container opening 221 is inserted into the sealing sleeve 141. After the ejector rod 112 pushes the valve core 242 to open the container opening 221, the atomization matrix can only enter the liquid storage chamber 110 along the sealing sleeve 141 and cannot enter the installation chamber 120, which helps to avoid the installation chamber 120 being contaminated by the atomization matrix.

[0046] In one embodiment, please refer to Figure 2 , a liquid guide pipe 113 is further provided in the liquid storage chamber 110. The liquid guide pipe 113 is sleeved outside the ejector rod 112. One end of the liquid guide pipe 113 is inserted into the sealing sleeve 141. A liquid outlet (not shown in the figure) communicating with the inner cavity of the liquid storage chamber 110 is provided on the liquid guide pipe 113. The provided liquid guide pipe 113 can guide the atomization matrix discharged from the liquid storage container 200, so that the atomization matrix can only be discharged into the liquid storage chamber 110 from the liquid outlet, which helps to limit the liquid discharge speed of the liquid storage container 200.

[0047] Exemplarily, the liquid guide tube 113 is a tube body with both ends open. One end of the liquid guide tube 113 abuts against the cavity wall of the liquid storage cavity 110 opposite to the sealing sleeve 141, and the other end is inserted into the sealing sleeve 141 and abuts against the end wall of the container opening 221. The part of the liquid guide tube 113 inserted into the sealing sleeve 141 tightly abuts against the annular protrusion 1412 on the inner wall of the sealing sleeve 141 to achieve the sealed connection between the liquid guide tube 113 and the sealing sleeve 141. In some embodiments, the liquid outlet can be covered in the liquid storage member 111 to further limit the liquid discharge speed of the liquid storage container 200 so that the liquid storage container 200 can be continuously used.

[0048] In one embodiment, please refer to Figure 2 , an annular slot 114 for inserting the end of the liquid guide tube 113 away from the sealing sleeve 141 is provided on the cavity wall of the liquid storage cavity 110. The setting of the annular slot 114 helps the liquid guide tube 113 to be assembled facing the sealing sleeve 141 so that the liquid guide tube 113 can be accurately inserted into the sealing sleeve 141.

[0049] In one embodiment, please refer to Figure 2 , the ejector rod 112 is inserted into the liquid guide tube 113. One end of the ejector rod 112 close to the annular slot 114 is supported on the support platform 1141 formed in the middle of the annular slot 114. A sealing ring 1121 is provided on the outer periphery of the ejector rod 112. The sealing ring 1121 is used to seal the gap between the ejector rod 112 and the tube wall of the liquid guide tube 113. The liquid outlet is provided on the part of the liquid guide tube 113 between the sealing ring 1121 and the sealing sleeve 141. With such a setting, the ejector rod 112 can be independently processed, which helps to reduce the processing difficulty. During assembly, the ejector rod 112 can be inserted into the liquid guide tube 113.

[0050] Improving the connection stability between the liquid storage container 200 and the atomizer 100 will also increase the difficulty of disassembling the liquid storage container 200. In this regard, in one embodiment, please refer to Figure 2 , an operation protrusion 250 exposed outside the installation opening 121 is provided on the container wall of the liquid storage container 200. Exemplarily, the operation protrusion 250 is provided on the container wall of the liquid storage container 200 on the side away from the container opening 221 and is located on the side of the liquid storage container 200 away from the mouthpiece 131 so as to pull out the liquid storage container 200 by using the operation protrusion 250.

[0051] In one embodiment, please refer to Figure 2 and Figure 3 , the atomizer 100 is provided with a relief groove 150 for avoiding the operation protrusion 250 at the installation opening 121. The setting of the relief groove 150 enables the operation protrusion 250 to be provided on one side of the liquid storage container 200, avoiding the operation protrusion 250 protruding along the insertion direction of the liquid storage container 200, which helps to improve the use convenience and aesthetics of the atomization device.

[0052] For a further embodiment, please refer to Figure 2 and Figure 3 The operating protrusion 250 is arranged obliquely. When the liquid storage container 200 is inserted into the installation cavity 120, there is an operating gap 151 between the operating protrusion 250 and the opposite groove wall 152, which is used for operation when removing the liquid storage container 200, and provides an operating space for removing the liquid storage container 200. Exemplarily, the operating protrusion 250 has a first side close to the liquid storage container 200 and a second side away from the liquid storage container 200. The clearance groove 150 has an opposite groove wall 152 opposite to the operating protrusion 250, and the first side is closer to the opposite groove wall 152 than the second side, that is, the side of the operating protrusion 250 away from the liquid storage container 200 is tilted away from the clearance groove 150.

[0053] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
