The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0044] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0045] See also Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides a detachable storage device 200, which includes a device body 9, an airtight bag assembly 5 and an exhaust assembly 7. The device body 9 has an outer shell that is hard or soft or a combination of hard and soft, and the outer shell can be opened and closed, so that a receiving chamber 90 that can be opened and closed is defined inside the outer shell. The exhaust assembly 7 is arranged on the device body 9. The airtight bag assembly 5 can be arranged in the receiving chamber 90, and the airtight bag assembly 5 can be connected to the exhaust assembly 7 to discharge the air in the airtight bag assembly 5 through the exhaust assembly 7 and compress and seal the contents in the airtight bag assembly 5.

[0046] Specifically, see Figure 2 、 Figure 3 As shown, the airtight bag assembly 5 includes an airtight bag 51 and a sealing cover 100. The airtight bag 51 is a flexible bag having a sealed cavity 510, and an air outlet (not shown) communicating with the sealed cavity 510 is provided on the airtight bag 51. Figure 2 、 Figure 5 and Figure 6 As shown, the blocking cover 100 includes a connecting portion 4 and a cover body 3. The connecting portion 4 is provided with an air outlet channel 40 extending therethrough. One end of the connecting portion 4 is sealedly connected to the airtight bag 51, and an air inlet end 401 of the air outlet channel 40 is in communication with the air outlet of the airtight bag 51. The cover body 3 includes a plug 31, which is detachably connected to the other end of the connecting portion 4.

[0047] The plug 31 has a first state and a second state. In the first state, see Figure 2 In conjunction with Figure 7 As shown, the plug 31 is configured to close the air outlet end 402 of the air outlet channel 40; in the second state, the plug 31 is configured to open the air outlet end 402 of the air outlet channel 40. At this time, since the air outlet end 402 of the air outlet channel 40 is open, the air outlet end 402 of the air outlet channel 40 is allowed to communicate with the exhaust component 7, and then, the exhaust component 7 is allowed to discharge the air in the sealed cavity 510.

[0048] The detachable storage device 200 provided in the embodiment of the present application has multiple flexible usage methods. For example, the exhaust component 7 is connected to the outlet end 402 of the air outlet channel 40, and after the airtight bag component 5 is exhausted and compressed, the whole can be placed in the accommodating chamber 90. For example, the exhaust component 7 is disconnected from the outlet end 402 of the air outlet channel 40, the plug 31 is connected to the connecting portion 4 and the outlet end 402 of the air outlet channel 40 is closed. At this time, the airtight bag component 5 remains compressed, and the airtight bag component 5 can be taken out from the accommodating chamber 90 and used alone, and the device body 9 can also be used alone. For another example, the plug 31 and the exhaust component 7 are both disconnected from the outlet end 402 of the air outlet channel 40. At this time, the airtight bag component 5 is naturally filled with air, and the airtight bag component 5 can be taken out from the accommodating chamber 90 and can be cleaned or replaced. In this way, the user's usage needs in multiple scenarios are met.

[0049] It is understood that the airtight bag 51 of the airtight bag assembly 5 is further provided with a switch component 512 such as an airtight zipper to allow the airtight bag assembly 5 to be opened and the contents to be taken out and placed. Figure 1 shown.

[0050] The type of the detachable storage device 200 provided in the embodiment of the present application is not limited. For example, the detachable storage device 200 can be a suitcase, a handbag, a backpack, or a storage box. Figure 1 The figure shows a suitcase as an example.

[0051] like Figure 1 As shown, the exhaust assembly 7 includes an exhaust pipe 72 and an exhaust pump 71. The exhaust pump 71 is fixed to the device body 9. The air inlet of the exhaust pipe 72 is used to communicate with the air outlet of the airtight bag 51, and the air outlet of the exhaust pipe 72 is used to communicate with the air inlet of the exhaust pump 71. Figure 3 In this way, the exhaust pipe 72 allows the relative positions of the exhaust assembly 7 and the airtight bag assembly 5 to be changed according to the state of the airtight bag assembly 5 during use, so as not to affect the airtightness of the connection between the two.

[0052] In the sealing cap 100, the plug 31 is a flexible member. In its natural state, the outer dimensions of the plug 31 are larger than the inner dimensions of the outlet end 402. The plug 31 is inserted into the outlet end 402 of the outlet channel 40. As a result, the plug 31 is compressed and deformed within the outlet channel 40. Thus, the plug 31 can be pressed tightly against the inner wall of the outlet channel 40, preventing air from entering the sealed cavity 510 through the outer periphery of the plug 31. Furthermore, friction between the plug 31 and the inner wall of the outlet channel 40 generates a force that stably maintains the plug 31 at a specific position within the outlet channel 40.

[0053] See also Figure 6 、 Figure 8 and Figure 9 As shown, the end of the plug 31 facing the airtight bag 51 can be designed to be concave, which can reduce the material used for the plug 31 and further increase its flexibility.

[0054] In one embodiment, Figure 2 、 Figure 6 and Figure 8 As shown, the cover 3 further includes a baffle 32, which is connected to the side of the plug 31 facing away from the airtight bag 51. The outer dimension of the baffle 32 is larger than the inner dimension of the air outlet end 402. In this way, the baffle 32 will not enter the air outlet channel 40. Compared with the plug 31 located in the air outlet channel 40, the baffle 32 is designed to protrude. This can not only prevent the plug 31 from entering the air outlet channel 40 too deeply, but also make it easier for the user to pull the plug 31 out of the air outlet channel 40 by holding the baffle 32.

[0055] Please continue to refer to 2. Figure 6 and Figure 8 As shown, the cover 3 also includes an outer shielding portion 33, which surrounds the plug 31 and is connected to the periphery of the baffle 32; a gap 30 is formed between the inner circumference of the outer shielding portion 33 and the inner surface of the plug 31; please refer to Figure 2 and Figure 6 As shown, the gap 30 is used for inserting the connecting portion 4. By providing the outer blocking portion 33, a larger operating area can be provided to the user, and the user can pull the cover body 3 as a whole from the connecting portion 4 through the outer blocking portion 33, which is convenient for the user to operate.

[0056] The outer dimensions of the connecting portion 4, here referring to the outer dimensions of the portion of the connecting portion 4 located within the outer shielding portion 33, are not limited in their size relationship to the inner dimensions of the outer shielding portion 33. For example, when the outer dimensions of the connecting portion 4 are smaller than the inner dimensions of the outer shielding portion 33, the outer shielding portion 33 may not contact the outer surface of the connecting portion 4; when the outer dimensions of the connecting portion 4 are equal to the inner dimensions of the outer shielding portion 33, the outer shielding portion 33 may directly contact the outer surface of the connecting portion 4; and when the outer dimensions of the connecting portion 4 are larger than the inner dimensions of the outer shielding portion 33, the outer shielding portion 33 may form an interference fit-like connection with the connecting portion 4.

[0057] In one embodiment, the outer shielding portion 33 is a flexible member.

[0058] In one embodiment, the outer shielding portion 33 is a flexible member, and the outer dimension of the connecting portion 4 is larger than the inner dimension of the outer shielding portion 33. When the outer shielding portion 33 is sleeved on the connecting portion 4, it also undergoes a certain degree of deformation.

[0059] In one embodiment, the plug 31, the baffle 32, and the outer shielding portion 33 are integrally formed. The cover 3 is a flexible member. For example, the plug 31, the baffle 32, and the outer shielding portion 33 are integrally formed into a flexible plastic member, a rubber member, or a silicone member.

[0060] See also Figure 2 、 Figure 6 and Figure 7 As shown, the connecting portion 4 includes a first connecting section 41 and a second connecting section 42 , and the air outlet channel 40 is set through the first connecting section 41 and the second connecting section 42 . The first connecting section 41 is used to connect to the airtight bag 51 , and the second connecting section 42 is used to connect to the plug 31 .

[0061] In one embodiment, the first connecting section 41 and the second connecting section 42 are connected in a bent manner, and accordingly, the air outlet channel 40 is also bent. Figure 2 、 Figure 3 and Figure 6 The purpose of such a configuration is to reduce the height of the connecting portion 4 relative to the surface of the airtight bag 51, thereby avoiding occupying too much space in the accommodating cavity 90 and affecting storage.

[0062] See also Figure 2 and Figure 7 As shown, one or more serrated sealing structures 421 are provided on the outer surface of the second connecting section 42. The top ends of these sealing structures 421 are used to contact the exhaust pipe 72 or the outer shielding portion 33. The serrated sealing structures 421 can reduce the contact area between the exhaust pipe 72, the outer shielding portion 33, and the second connecting section 42, thereby concentrating the stress exerted by the sealing structures 421 on the exhaust pipe 72 and the outer shielding portion 33, thereby enhancing airtightness and preventing air leakage. At the same time, the friction between the sealing structures 421, the exhaust pipe 72, and the outer shielding portion 33 is increased, further preventing problems such as falling off and air leakage.

[0063] like Figure 3 、 Figure 5 and Figure 9 As shown, the cover 3 also includes an anti-slip member 34, one end of which is connected to the plug 31, and the other end of which is connected to the connecting portion 4. The other end of the anti-slip member 34 is configured to be movably connected to the connecting portion 4, and / or the anti-slip member 34 is a flexible member. The purpose of this arrangement is that when the plug 31 is pulled out of the air outlet channel 40, the plug 31 can still be connected to the connecting portion 4 by means of the anti-slip member 34. Figure 3 As shown, the plug 31 is not easily lost, which is convenient for users to use. More importantly, when the plug 31 is pulled out, the shape of the anti-slip part 34 and / or its position relative to the connecting part 4 can change accordingly to adapt to the position of the plug 31.

[0064] In an optional embodiment, the other end of the anti-slip member 34 is annular and is sleeved on the first connecting section 41. The inner dimension of the other end of the anti-slip member 34 is larger than the outer dimension of the first connecting section 41, but smaller than the outer dimension of the connection between the first connecting section 41 and the second connecting section 42, or smaller than the outer dimension of the second connecting section 42. The purpose of this arrangement is that the other end of the anti-slip member 34 can be movably sleeved on the first connecting section 41, but cannot pass through the connection between the first connecting section 41 and the second connecting section 42 or cannot pass through the second connecting section 42. In this way, on the basis of preventing the plug 31 from being lost, the position of the plug 31 and the anti-slip member 34 relative to the connecting portion 4 can be more flexible, so that they can be flexibly placed in the accommodating cavity 90, such as being straightened.

[0065] Please refer to Figure 9 and Figure 10 As shown, in one embodiment, the anti-slip member 34 is a flexible member.

[0066] In one embodiment, the anti-slip member 34 is a flexible member, and the other end of the anti-slip member 34 is movably connected to the first connecting section 41 .

[0067] In one embodiment, the anti-slip member 34 is integrally formed with the plug 31, the baffle 32, and the outer shielding portion 33. For example, the anti-slip member 34 is integrally formed with the plug 31, the baffle 32, and the outer shielding portion 33 and is a flexible plastic member, rubber member, or silicone member.

[0068] The connecting portion 4 may be an integrally formed part, such as an integrally injection-molded plastic part, etc. The specific material of the connecting portion 4 is not limited, and optionally, the cover 3 is softer than the connecting portion 4 .

[0069] See also Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the end of the first connecting section 41 facing the airtight bag 51 forms an annular connecting edge 410, which is used to fit and seal the airtight bag 51. Since the connecting edge 410 is flat, it can provide a larger contact area for connection with the airtight bag 51, thereby ensuring the stability and airtightness of the connection between the first connecting section 41 and the airtight bag 51, and avoiding the problem of air leakage at the connection between the first connecting section 41 and the airtight bag 51.

[0070] Among them, such as Figure 2 and Figure 3 As shown, the connecting edge 410 can be located inside the airtight bag 51 and connected to the inner wall of the airtight bag 51, and the rest of the first connecting section 41 can be located outside the airtight bag 51. Alternatively, the connecting edge 410 can be located outside the airtight bag 51 and connected to the outer wall of the airtight bag 51. Any method is sufficient as long as the two can be stably connected.

[0071] like Figures 1 to 3 As shown, in one embodiment, the detachable storage device 200 further includes a vent cover 8, which is arranged on the inner wall of the airtight bag 51 and surrounds the air outlet of the airtight bag 51. A plurality of vents 80 are provided on the circumference of the vent cover 8, and the vents 80 are connected to the air outlet of the airtight bag 51. Since the vent cover 8 has a certain height, it defines a support space 81 inside the airtight bag 51, as shown in FIG. Figure 2 and Figure 3 As shown, the support space 81 can prevent the contents, such as soft clothes, from directly covering the air outlet of the airtight bag 51 and sealing the air outlet of the airtight bag 51. Therefore, the vent cover 8 can ensure that the air outlet of the airtight bag 51 is connected to the air outlet channel 40.

[0072] Alternatively, as Figure 2 and Figure 3 As shown, when the connecting edge 410 is provided on the inner wall of the airtight bag 51, the connecting edge 410 is also located inside the vent cover 8. This is conducive to the vent cover 8 being directly connected to the inner wall of the airtight bag 51 without being affected by the connecting edge 410.

[0073] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
