In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 , Figure 2 As shown, the present application provides an earphone charging box 10, which includes a box body 100 and a charging column assembly 200.

[0038] Combination Figure 1 and Figure 2 The box body 100 is provided with an earphone slot 140 .

[0039] Specifically, the box body 100 includes a lower shell component 110, a middle shell component 130 disposed in the lower shell component 110, and an upper shell component 120 rotatably connected to the lower shell component 110, wherein the earphone slot 140 is disposed on the middle shell component 130. When the lower shell component 110 is in a closed state, the earphone slot 140 is closed, and when the lower shell component 110 is in an open state, the earphone slot 140 is exposed. The earphone slot 140 is used for placing earphones, and the earphones can be charged after being placed in the earphone slot 140.

[0040] It can be understood that there are two earphone slots 140 , one of which is used for receiving a left earphone, and the other earphone slot 140 is used for receiving a right earphone.

[0041] Among them, the earphones are Bluetooth earphones, and the earphones can be configured with call noise reduction function and / or artificial intelligence noise reduction function; at the same time, the earphones can also be configured with stereo surround and other functions.

[0042] It should be noted that, depending on the model of the earphone, the earphone slot 140 can also be set to different shapes.

[0043] In some embodiments, the earphone slot 140 is configured to be in a shape that conforms to the placement of an in-ear earphone; in some other embodiments, the earphone slot 140 is configured to be in a shape that conforms to the placement of an earhook earphone.

[0044] like Figures 3 to 5 As shown, further, the box body 100 is also provided with a mounting hole 150 penetrating the groove wall of the earphone groove 140 .

[0045] Specifically, the mounting hole 150 is opened in the middle shell component 130 , and the top end of the mounting hole 150 passes through the groove wall of the earphone groove 140 .

[0046] It is understandable that the mounting hole 150 can be perpendicular to the horizontal plane or at a certain inclination.

[0047] Specifically, the angle between the axial direction of the mounting hole 150 and the vertical direction is in the range of 0-10°.

[0048] The charging column assembly 200 includes a mounting sleeve 210 , an elastic member 220 , a charging column 230 and a guide cap 240 .

[0049] The installation sleeve 210 is a structure with a closed bottom and an open top.

[0050] Specifically, the mounting sleeve 210 is a hollow structure with an opening at the top, and the bottom end of the mounting sleeve 210 is closed. At least a portion of the mounting sleeve 210 is disposed in the mounting hole 150 , and the top end of the mounting sleeve 210 is disposed toward the earphone slot 140 .

[0051] It should be noted that the mounting sleeve 210 can be limited and fixed in the box body 100 by other components, the upper part of the mounting sleeve 210 is inserted into the mounting hole 150, and the mounting sleeve 210 and the mounting hole 150 are coaxially arranged, and the mounting sleeve 210 and the top of the mounting hole 150 are arranged opposite to each other.

[0052] The elastic member 220 is disposed in the mounting sleeve 210 .

[0053] The elastic member 220 may be a spring. The elastic member 220 is disposed in the installation sleeve 210 and is limited by the installation sleeve 210 . The bottom end of the elastic member 220 abuts against the bottom end of the installation sleeve 210 .

[0054] The bottom end of the charging column 230 is inserted into the mounting sleeve 210 through the top end of the mounting sleeve 210 , and the charging column 230 abuts against the elastic member 220 , and the top end of the charging column 230 extends into the earphone slot 140 .

[0055] It is understandable that the charging column 230 is inserted into the mounting sleeve 210 from top to bottom until it abuts against the elastic member 220 , and the elastic member 220 can apply an elastic force to the charging column 230 .

[0056] like Figure 6 , Figure 7 As shown, further, a positioning hole 231 is provided at the bottom end of the charging column 230, and the top of the elastic member 220 is inserted into the positioning hole 231. The positioning hole 231 has a positioning effect on the elastic member 220, which can ensure the position accuracy between the elastic member 220 and the charging column 230.

[0057] In some embodiments, the charging column 230 cooperates with the inner wall guide of the mounting sleeve 210, and the mounting sleeve 210 can guide the charging column 230, thereby ensuring that the charging column 230 moves up and down normally.

[0058] like Figures 5 to 7 As shown, the guide cap 240 is covered on the top of the charging column 230 .

[0059] First of all, it should be explained that the deflector cap 240 is a conductive component. The deflector cap 240 is covered on the top of the charging column 230 and extends into the earphone slot 140. When the deflector cap 240 contacts the charging terminal on the earphone, the earphone can be charged.

[0060] Furthermore, a guide portion 241 is provided on the side of the guide cap 240; a plane perpendicular to the axis of the mounting hole 150 is defined as a reference plane, and the projection of the outer peripheral edge of the guide portion 241 on the reference plane surrounds the projection of the outer peripheral edge of the top of the mounting sleeve 210 on the reference plane.

[0061] It can be understood that the projection of the outer edge of the guide portion 241 on the reference plane is defined as the first projection, and the projection of the outer edge of the top of the mounting sleeve 210 on the reference plane is defined as the second projection, and the first projection surrounds the second projection. In this way, when sweat or other liquid enters the mounting hole 150, the risk of sweat entering the mounting sleeve 210 through the top opening of the mounting sleeve 210 can be reduced under the action of the guide portion 241. In this way, the risk of sweat crystallizing in the mounting sleeve 210 and affecting the normal operation of the elastic member 220 can be reduced, and the risk of sweat corroding the mounting sleeve 210 and the elastic member 220 can also be reduced.

[0062] It can be understood that when the axial direction of the mounting hole 150 is parallel to the vertical direction, the sweat flowing downward through the guide portion 241 can directly avoid the top opening of the mounting sleeve 210, thereby reducing the risk of sweat entering the mounting sleeve 210 through the top opening of the mounting sleeve 210; when the axial direction of the mounting hole 150 is at a certain angle to the vertical direction, the sweat will first flow to a lower place when flowing on the guide portion 241, and then drip down at a lower position of the guide portion 241, which can also reduce the risk of sweat entering the mounting sleeve 210 through the top opening of the mounting sleeve 210.

[0063] like Figure 7 As shown, in some embodiments, the outer side wall of the guide portion 241 includes a guide cone surface 2411, and the diameter of the guide cone surface 2411 gradually increases from top to bottom.

[0064] It is understandable that when sweat is contaminated by the guide cap 240 , the sweat will flow downward to the guide portion 241 , and will gradually flow outward under the action of the guide cone 2411 of the guide portion 241 , thereby reducing the risk of sweat entering the mounting sleeve 210 through the top opening of the mounting sleeve 210 .

[0065] Furthermore, the outer wall of the guide portion 241 also includes a cylindrical surface 2412 connected below the guide cone 2411. In this way, when sweat continues to flow downward from the lower edge of the guide cone 2411, it can flow downward along the cylindrical surface 2412, reducing the risk of sweat flowing inward and dripping onto the mounting sleeve 210.

[0066] like Figure 5 As shown, in some embodiments, a limiting portion 151 is provided at the upper end of the mounting hole 150 , and the guide portion 241 is limitedly matched with the lower end of the limiting portion 151 .

[0067] Specifically, the limiting portion 151 is arranged at the top of the mounting hole 150, and the limiting portion 151 is surrounded by a through hole for the charging column 230 and the guide cap 240 to pass through. The limiting portion 151 limits the guide portion 241, thereby preventing the guide cap 240 from falling out of the mounting hole 150 and becoming ineffective.

[0068] There is a gap between the hole wall of the through hole and the outer side wall of the guide cap 240 , so that when the guide cap 240 moves in the through hole, the guide cap 240 can be prevented from being worn by the hole wall of the through hole.

[0069] Furthermore, a conical surface is provided at the inner edge of the lower end of the limiting portion 151, and the conical surface is limitedly matched with the guide conical surface 2411. In this way, when the conical surface contacts the guide conical surface 2411 to limit the guide cap 240 from coming out of the mounting hole 150, the conical surface and the guide conical surface 2411 have a large contact area, which can reduce the pressure between the limiting portion 151 and the guide cap 240, and reduce the risk of wear of the limiting portion 151 and the guide cap 240.

[0070] like Figure 5 As shown, in some embodiments, the limiting portion 151 is arranged to protrude from the groove wall of the earphone groove 140. In this way, the limiting portion 151 can play the role of a barrier. When the earphone groove 140 is stained with sweat, the risk of the sweat in the earphone groove 140 flowing into the mounting hole 150 can be reduced under the blocking effect of the limiting portion 151.

[0071] In some embodiments, the guide cap 240 is interference fit with the charging column 230. In this way, the guide cap 240 and the charging column 230 can be fixed together, and the guide cap 240 can move with the charging column 230, which can prevent the guide cap 240 from being in a loose state. At the same time, it can also ensure that the guide cap 240 and the charging column 230 are in close contact, ensuring that the current is conducted between the two, and providing a reliable charging effect for the headset.

[0072] In some other embodiments, adhesive may be used to further improve the connection reliability between the guide cap 240 and the charging column 230 .

[0073] The present application also provides an earphone kit, including: an earphone charging box 10 and an earphone, and the earphone is removably arranged in the earphone slot 140.

[0074] The earphone kit of the utility model has the above-mentioned earphone charging box 10. When sweat or other liquids enter the mounting hole 150, the risk of sweat entering the mounting sleeve 210 through the top opening of the mounting sleeve 210 can be reduced under the action of the guide portion 241. In this way, the risk of sweat crystallizing in the mounting sleeve 210 and affecting the normal operation of the elastic member 220 can be reduced, and the risk of sweat corroding the mounting sleeve 210 and the elastic member 220 can also be reduced.
