DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a device for replacing an atomizer, referring to Figure 1 , Figure 2 and Figure 3 , including an atomizer tank 1 and a mask 2, wherein a ventilation pipe 11 connected to the interior of the atomizer tank 1 is provided on the outer wall of the atomizer tank 1, one end of the mask 2 is an opening for fitting on the human face, and the other end is connected to a first connecting pipe 21, the interior of the first connecting pipe 21 is a through channel that connects the two ends of the mask 2, and the mask 2 is connected to the ventilation pipe 11 through the first connecting pipe 21.

[0020] Specifically, a first connecting ring 211 is integrally and coaxially protruded on the outer wall of the first connecting tube 21 at a position far from the mask 2, and a first flexible sleeve 212 is sleeved on the outer side of the first connecting ring 211. A section of the first flexible sleeve 212 close to the mask 2 is fixedly bonded to the outer wall of the first connecting tube 21, and the other end of the first flexible sleeve 212 is movably covered on the outer wall of the first connecting tube 21. A first abutting ring 213 is also coaxially and fixedly connected to the outer wall of the first flexible sleeve 212. The first abutting ring 213 can be made of the same flexible material as the first flexible sleeve 212, or can be made of a hard plastic material fixedly bonded to the outer wall of the first flexible sleeve 212. A first positioning ring 111 is integrally fixedly provided on the inner wall of one end of the ventilation pipe 11 away from the atomizer tank 1. The inner diameter of the first positioning ring 111 is larger than the outer diameters of the first flexible sleeve 212 and the first connecting ring 211. In addition, the difference between the inner ring radius of the first positioning ring 111 and the outer ring radius of the first connecting ring 211 should be smaller than the thickness of the first flexible sleeve 212. The first positioning ring 111 can abut against the first abutment ring 213. A first positioning step 214 for limiting the movement of the first abutment ring 213 is provided on the first connecting pipe 21 at a side of the first connecting ring 211 close to the mask 2.

[0021] When connecting the mask 2 to the atomizer tank 1, align the first connecting tube 21 with the ventilation tube 11 and insert it, so that both the first flexible sleeve 212 and the first connecting tube 21 pass through the first positioning ring 111. When the first positioning ring 111 contacts the first abutting ring 213, the first positioning ring 111 pushes the first abutting ring 213 to move on the first connecting tube 21. The operator needs to forcefully push the first connecting tube 21 to move toward the ventilation tube 11, so that the first positioning ring 111 passes from the outside of the first connecting ring 211 on the first connecting tube 21. In the embodiment of the present application, after the first positioning ring 111 passes through the first connecting ring 211, the two are spaced 1mm-3mm in the axial direction of the first connecting tube 21, and the first positioning step 214 on the first connecting tube 21 conflicts with the first abutting ring 213, limiting the first connecting tube 21 from being inserted into the first ventilation tube 11. At this time, the first flexible sleeve 212 is squeezed and deformed between the first positioning ring 111 and the first connecting ring 211, and the first flexible sleeve 212 rebounds to fill the gap between the first positioning ring 111 and the first connecting ring 211, and simply restricts the first connecting tube 21 from being separated from the first ventilation tube 11. When the mask 2 needs to be separated and replaced, the first connecting tube 21 is pulled out of the first ventilation tube 11 with reverse force, and the first flexible sleeve 212 can automatically and elastically return to its original position.

[0022] Compared with the threaded connection, the first connecting tube 21 and the ventilation tube 11 are connected through the elastic deformation of the first flexible sleeve 212, which reduces the direct contact between the hard plastic parts and reduces the wear. In addition, by movably sleeve-connecting one end of the first flexible sleeve 212 on the first connecting tube 21, the thickness of the first flexible sleeve 212 on the side of the first abutting ring 213 away from the mask 2 can be appropriately thickened. After the first connecting tube 21 is connected to the ventilation tube 11, the first flexible sleeve 212 can better fill the gap between the first connecting ring 211 and the first positioning ring 111, thereby improving the connection sealing performance between the mask 2 and the atomizer tank 1. At the same time, when the first connecting tube 21 is plugged in and out for multiple times, the deformation force of the connection part between the first flexible sleeve 212 and the first connecting tube 21 is small, and the damage to the first flexible sleeve 212 is small.

[0023] Furthermore, a limiting step 112 is coaxially arranged on the side of the first positioning ring 111 close to the atomizer tank 1 in the vent pipe 11. When the first connecting pipe 21 is plugged and matched with the vent pipe 11, that is, the first positioning ring 111 is located on the side of the first connecting ring 211 close to the mask 2, the first connecting pipe 21 is plugged and matched with the limiting step 112, which can improve the coaxiality of the first connecting pipe 21 and the vent pipe 11 when plugged and matched, and avoid the shaking of the first connecting pipe 21. The step surface of the limiting step 112 away from the atomizer tank 1 can also be set as a conical guide surface, so as to play a guiding and correcting role for the first connecting pipe 21 during the plugging process of the first connecting pipe 21.

[0024] Furthermore, the first positioning ring 111 is provided with expansion and contraction seams 113. In the embodiment of the present application, six expansion and contraction seams are provided. By providing the expansion and contraction seams, when the first connecting tube 21 is plugged in and out, a margin of movement is provided for the deformation of the first flexible sleeve 212, thereby preventing the first positioning ring 111 from expanding and being damaged during the process of plugging and unplugging the first connecting tube 21 with force.

[0025] In the embodiment of the present application, a bite tube 3 is also included, which is detachably connected to the mask 2, allowing the user to choose to inhale mist from the nasal cavity through the mask 2 or from the mouth through the bite tube 3 according to the use environment. In the embodiment of the present application, one end of the occlusal tube 3 is provided with a bite opening 31, and the other end is used to be coaxially connected to the second connecting tube 22. A second connecting ring 32 is protrudingly provided on the outer wall of the occlusal tube 3, and a second flexible sleeve 33 is sleeved on the outer side of the second connecting ring 32. The end of the second flexible sleeve 33 close to the bite opening 31 is fixedly connected to the occlusal tube 3, and a second abutment ring 34 is coaxially protrudingly provided on the outer wall of the second flexible sleeve 33. A second positioning ring 221 is protruding inwardly at the end of the second connecting tube 22 away from the first connecting tube 21. The inner diameter of the second positioning ring 221 is larger than the outer diameter of the second flexible sleeve 33 and the second connecting ring 32, and is used to abut with the second abutment ring 34. A second positioning step 222 for limiting the movement of the second abutment ring 34 is provided on the side of the second connecting ring 32 close to the bite opening 31 on the occlusal tube 3. The connection method between the bite tube 3 and the second connecting tube 22 is the same as the connection method between the first connecting tube 21 and the ventilation tube 11, which will not be repeated here. Through this method, the wear on the bite tube 3 and the second connecting tube 22 can be reduced.

[0026] In the embodiment of the present application, the first flexible sleeve 212 and the second flexible sleeve 33 are both made of medical silicone material, which is non-toxic, soft, highly elastic and wear-resistant, and is suitable for frequent insertion and removal of the mask 2 or the bite tube 3 in the home.
