Abstract
Description
Technical Field
[0001] This utility model relates to a charging case, and more particularly to a multifunctional headphone charging case. Background Technology
[0002] Earphone charging cases are portable charging devices designed specifically for wireless earphones and are usually sold together with the earphones. Due to their small size and convenience, earphone charging cases are suitable for various occasions such as daily commutes and travel.
[0003] Existing Bluetooth earphone charging cases mainly focus on storing and charging the earphones, with relatively simple functions. For users who travel frequently, they may need to prepare fruit on the spot, and users usually need to carry knives separately, which not only increases the complexity of luggage, but may also bring safety hazards. Utility Model Content
[0004] In order to overcome the shortcomings of existing Bluetooth earphone charging cases, which are limited to storage and charging and require users to carry knives separately if they need to prepare fruit while traveling, thus increasing luggage burden and potentially posing safety hazards, this utility model provides a multi-functional earphone charging case.
[0005] The technical solution is as follows: A multi-functional earphone charging case includes a lid, a body, a first elastic protrusion, a power indicator light, a button, an LED light, a small folding knife, and a protective ring. The lid is hinged to the top of the body, and the small folding knife is hinged to the rear of the body. A knife groove is formed on the right side of the body, and the small folding knife is located in the knife groove. The first elastic protrusion is symmetrically arranged vertically in the knife groove. A first limiting groove is formed on the blade of the small folding knife, and the first limiting groove fits with the first elastic protrusion. A second elastic protrusion is symmetrically arranged vertically in the knife groove near the hinge of the small folding knife. A second limiting groove and a third limiting groove are formed on the handle of the small folding knife, and both the second and third limiting grooves fit with the second elastic protrusion. When the small folding knife is closed, the third limiting groove corresponds to the position of the second elastic protrusion. When the small folding knife is open, the second limiting groove corresponds to the position of the second elastic protrusion. A protective ring is provided on the handle of the small folding knife. A power indicator light, a button, and an LED light are provided on the outside of the body.
[0006] Furthermore, the handle of the small folding knife has finger grooves.
[0007] Furthermore, the protective ring is made of natural leather.
[0008] Furthermore, it also includes a pull ring; the back of the small folding knife has a pull ring.
[0009] Furthermore, it also includes a dust plug, which is detachably connected to the charging port in the middle of the rear side of the box.
[0010] Furthermore, a portion of the top of the box lid is designed with a semi-transparent material.
[0011] The beneficial effects of this utility model are as follows: This utility model not only has the basic functions of storing and charging headphones, but also integrates multiple functions such as a safe and convenient small folding knife, LED light and power indicator. For users who travel frequently, when they need to process fruit on the spot, they no longer need to carry an extra knife, reducing the burden of luggage and simplifying travel equipment.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] A multi-functional earphone charging case, such as Figures 1-5As shown, the device includes a lid 1, a body 2, a first elastic protrusion 201, a power indicator light 3, a button 5, an LED light 501, a small folding knife 6, and a protective ring 8. The lid 1 is hinged to the top of the body 2, and the small folding knife 6 is hinged to the rear side of the body 2. A knife groove 202 is opened on the right side of the body 2, and the small folding knife 6 is located in the knife groove 202. The size of the small folding knife 6 fits the knife groove 202. When the small folding knife 6 is stored in the knife groove 202, its blade tip is completely hidden. Concealed from the outside, the blade groove 202 is symmetrically provided with first elastic protrusions 201 arranged vertically. The blade of the small folding knife 6 has a first limiting groove 601, which fits into the first elastic protrusion 201. The portion of the blade groove 202 near the hinge of the small folding knife 6 has symmetrically provided second elastic protrusions arranged vertically. The handle of the small folding knife 6 has a second limiting groove 602 and a third limiting groove 603. All three parts 3 are matched with the second elastic protrusion. When the small folding knife 6 is closed, the third limiting groove 603 corresponds to the position of the second elastic protrusion to prevent the closed small folding knife 6 from being accidentally opened. When the small folding knife 6 is fully opened, the second limiting groove 602 corresponds to the position of the second elastic protrusion. The handle of the small folding knife 6 is provided with a protective ring 8. The protective ring 8 is made of natural leather. When the small folding knife 6 is closed, the protective ring 8 can deform and will not interfere with or occupy the internal space of the earphone charging case. The handle of the small folding knife 6 is provided with a finger groove 9. The finger groove 9 provides a place for the finger, reducing the risk of the small folding knife 6 accidentally slipping and reducing the possibility of accidental injury. The outer side of the case 2 is provided with a power indicator light 3, a button 5 and an LED light 501. The button 5 and the LED light are connected by electrical signals. The power indicator light 3 can directly display the remaining power of the earphone charging case. Users can charge the earphone charging case in time according to the accurate power information.
[0020] like Figure 5 As shown, it also includes a pull ring 7. The small folding knife 6 has a pull ring 7 on the back of the blade. The pull ring 7 provides a gripping structure, making it easy for the user to pull the small folding knife 6 out of the blade groove 202.
[0021] like Figure 2 As shown, it also includes a dust plug 4. The dust plug 4 is detachably connected to the charging port in the middle of the rear side of the box 2. The dust plug 4 can protect the charging port from the intrusion of dust, sand and other tiny particles.
[0022] like Figure 1 As shown, a portion of the top of the lid 1 is designed with a semi-transparent material, allowing users to check whether the earphones have been placed inside the earphone charging case without opening the lid 1.
[0023] When fruit needs to be processed, pull the small folding knife 6 out of the blade groove 202 using the pull ring 7, then rotate it to the fixed position until the second limiting groove 602 engages with the second elastic protrusion. At this point, the small folding knife 6 is fixed. The user inserts their index finger into the finger groove 9 and presses the back of the handle of the small folding knife 6 with their thumb to firmly control the small folding knife 6, preventing it from slipping during cutting and thus reducing the risk of use. Finally, swing the small folding knife 6 to cut the fruit peel. After cutting, wipe the peel and other residues on the blade of the small folding knife 6 with a paper towel. To apply juice, remove your index finger from the finger groove 9 and press the back of the handle of the small folding knife 6. The second elastic protrusion is squeezed by the second limiting groove 602 and disengages from it. Continue pressing the small folding knife 6 until it moves into the knife groove 202. The first limiting groove 601 and the third limiting groove 603 on the small folding knife 6 are respectively embedded into the first elastic protrusion 201 and the second elastic protrusion to fix the small folding knife 6 and prevent it from sliding out of the knife groove 202. When lighting is needed, press the button 5 to turn on the LED light 501 to provide sufficient light.
[0024] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
