[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example

[0033] like Figures 1 to 7 As shown, the present invention includes a housing 1 and a lid 3. The housing 1 is provided with a receiving cavity 4 for placing an earphone 2. The inner wall of the receiving cavity 4 is provided with a first airbag 5, which can expand within the receiving cavity 4. The housing 1 is also provided with an inflation component 6, which is used to inflate the first airbag 5 and to fit the first airbag 5 into the earpiece of the earphone 2 located within the receiving cavity 4.

[0034] In existing technologies, the shape of the receiving cavity 4 inside the housing 1 is usually slightly larger than the outer shape of the earphone 2. This is to reduce friction between the earphone 2 and the inner wall of the receiving cavity 4 when the earphone 2 is inserted into or removed from the receiving cavity 4, thereby reducing wear on the earphone 2 shell and facilitating user insertion and removal of the earphone 2. However, this design results in a certain gap between the earphone 2 and the inner wall of the receiving cavity 4 of the housing 1. Therefore, if the housing 1 is accidentally dropped, the earphone 2 inside the housing 1 will collide violently within the receiving cavity 4, potentially damaging the internal components of the earphone 2. Therefore, this technical solution addresses this issue in existing housing... A first airbag 5 is provided on the inner wall of the receiving cavity 4 of the body 1. At the same time, an inflation component 6 for inflating the first airbag 5 is also provided on the body 1. When the user puts the earphone 2 back into the receiving cavity 4 after use, the user uses the inflation component 6 to inflate the first airbag 5. The inflated first airbag 5 can expand in the receiving cavity 4, thereby filling the gap between the earphone 2 and the receiving cavity 4. In this way, when the body 1 is dropped, the inflated first airbag 5 can provide a certain degree of protection for the earphone 2, avoiding violent collision between the earphone 2 and the inner wall of the receiving cavity 4, thus achieving a certain degree of protection for the earphone 2.

[0035] Meanwhile, after the earphone 2 is used for a long time, the earphone 2 is inevitably attached with earwax and other impurities, so that the user needs to wipe the earwax attached to the earphone 2 after each use. However, since the first air bag member 5 arranged in the accommodating cavity 4 can be sleeved on the earphone 2 after inflation, the first air bag member 5 arranged in the accommodating cavity 4 can extrude the earphone 2 during the process of gradually expanding and becoming larger, and the first air bag member 5 can rub against the earphone 2 during the extrusion process, so that the earwax attached to the earphone 2 can be wiped off, thereby achieving the purpose of automatically cleaning the earwax attached to the earphone 2. Therefore, the first air bag member 5 arranged in the process of gradually expanding and becoming larger can not only generate a certain friction force on the earphone 2, thereby achieving the purpose of removing the earwax attached to the earphone 2, but also can be filled in the gap between the accommodating cavity 4 and the earphone 2 after expansion and becoming larger, thereby achieving the purpose of protecting the earphone 2.

[0036] The inner wall of the accommodating cavity 4 is provided with a limiting groove, and the outer wall of the first air bag member 5 is provided with a limiting block with elasticity, which is clamped in the limiting groove.

[0037] In the embodiment, after the first air bag member 5 is used for a period of time, in order to facilitate the disassembly or replacement of the first air bag member 5 arranged in the accommodating cavity 4 and facilitate the regular cleaning of the earwax attached to the first air bag member 5, since the first air bag member 5 is clamped in the limiting groove of the accommodating cavity 4 through the limiting block, when disassembling, the user only needs to exert a little pulling force on the first air bag member 5, so that the limiting block with elasticity can be pulled out of the limiting groove, thereby taking out the first air bag member 5 from the accommodating cavity 4.

[0038] The inflator 6 includes a second air bag member 10 and an extrusion plate 7, the bottom of the box body 1 is provided with a recess, the second air bag member 10 and the extrusion plate 7 are located in the recess, the inner wall of the recess is provided with a limiting protrusion, the side wall of the extrusion plate 7 is provided with a limiting groove, the limiting groove is in communication with the end face of the extrusion plate 7 away from the second air bag member 10, the limiting protrusion is located in the limiting groove, and the second air bag member 10 is in communication with the first air bag member 5.

[0039] In the embodiment, in order to ensure that the arranged inflator 6 can inflate the first air bag member 6, the arranged inflator 6 includes a second air bag member 10 and an extrusion plate 7. When the user presses the extrusion plate 7 in the direction of the second air bag member 10, the extrusion plate 7 can compress the arranged second air bag member 10, so that the internal air is extruded into the first air bag member 5, thereby achieving the purpose of inflating the first air bag member 5.

[0040] In order to achieve the reciprocating extrusion of the second air bag 10, the box body 1 is further provided with an air inlet 9 in communication with the second air bag 10, the air inlet 9 is provided with a first one-way valve, the communication position of the first air bag 5 and the second air bag 10 is provided with a second one-way valve, the first one-way valve can ensure that the gas in the outside enters the second air bag 10, and the air in the second air bag 10 cannot be discharged to the outside through the one-way valve; and the second one-way valve ensures that the air in the second air bag 10 can be transmitted to the first air bag 5, and the air in the first air bag 5 cannot flow back to the second air bag 10, and a plurality of second elastic members are further arranged in the first air bag 5, so that when the pressing plate 7 is pressed, the pressing plate 7 transmits the air in the second air bag 10 to the first air bag 5 through the second one-way valve, and after the acting force on the pressing plate 7 is removed, the second air bag 10 can be forced to quickly restore the deformation under the action of the second elastic member, and the negative pressure is generated in the second air bag 10 in the process of restoring the deformation, so that the air in the outside is sucked into the second air bag 10 through the first one-way valve, thereby realizing the repeated inflation of the first air bag 5, and the purpose of fully expanding and increasing is achieved.

[0041] In the embodiment, the limiting protrusion is arranged to prevent the pressing plate 7 from being separated from the limiting groove.
