Description

Technical Field

[0001] This invention relates to the field of earbud case technology and provides an earbud case for manually squeezing earbuds. Background Technology

[0002] In noisy factory and production workshop environments, workers need to wear earplugs to reduce noise damage to their hearing and ensure effective hearing protection during work. Due to prolonged exposure to noise, especially in work environments with concentrated noise sources such as machinery operation and metal processing, the use of earplugs has become an essential safety measure.

[0003] However, the working environment inside factories is quite complex, especially in processing workshops where oil stains, dust, and other contaminants are common. These contaminants easily adhere to the hands of workers. When workers put on and handle earplugs, these contaminants from their hands can contaminate the surface of the earplugs, making them dirty. Using dirty earplugs can lead to adverse reactions such as ear infections, inflammation, and itching, affecting the health of workers.

[0004] Currently, some earphone cases on the market have a crushing function, which typically uses clamping force to flatten the earphones for easier wearing. These earphone cases work by using a mechanical structure to generate a certain clamping force to flatten the earphones, thus helping them conform to the shape of the ear canal. However, existing earphone cases have certain problems in actual use. Some products have insufficient clamping force, failing to effectively flatten the earphones, causing them to not fit smoothly into the ear canal and affecting the wearing experience; others use a mechanical structure to cross-crush the earphones, which may damage the earphone's material and shape over time. For example, a Chinese invention patent published on August 13, 2024, entitled "Earphone Case with Compression Deformation Function" (application number: 202410688459.9), proposes an earphone case that flattens the earphones using two sets of interlocking grooves inside. However, due to friction and shearing forces, the increased force can easily damage the earphones.

[0005] Furthermore, and most importantly, these mechanically shaped, crushing mechanisms cannot meet users' individual needs and cannot provide the same effect as manually crushing the earbuds. Therefore, in actual use, users tend to prefer to manually crush the earbuds to achieve the desired effect.

[0006] Therefore, there is an urgent need for an earphone case that can both ensure the cleanliness and hygiene of the earphones and meet the needs of different users. Summary of the Invention

[0007] To address the aforementioned deficiencies, the present invention aims to provide an earplug case for manually squeezing earplugs, thereby solving the problems mentioned in the background art. The earplug case includes a soft outer shell that can hold earplugs and isolate them from the outside world. The soft outer shell has a storage space inside that can hold two earplugs individually. Users can squeeze the earplugs inside the soft outer shell to deflate them. The soft outer shell is provided with a cover that can open or close the soft outer shell.

[0008] Furthermore, the earbud case includes a supporting main frame, the cover is hinged to the top of the main frame, a soft shell is installed at the bottom of the main frame, and soft plug shells matching the size and number of earbuds are installed inside the soft shell.

[0009] Furthermore, an isolation plate is installed on the main body frame, and the soft plug shell is installed inside the earplug case through the isolation plate.

[0010] Furthermore, the connection between the main body frame and the soft shell is a combination of snap-fit ​​and adhesive connection.

[0011] Furthermore, the main body frame is provided with a snap-fit ​​groove that matches the shape of the side of the isolation plate, and the isolation plate is snapped into the snap-fit ​​groove.

[0012] Furthermore, a first magnetic attraction point is provided on the side of the main body frame away from the hinge point with the cover, and a second magnetic attraction point is provided on the cover to correspond to and cooperate with the first magnetic attraction point.

[0013] Furthermore, a sealing strip is fixedly connected to the top surface of the main body frame.

[0014] Furthermore, the main body frame is fixedly installed with buckles.

[0015] Furthermore, the soft shell is provided with vents for maintaining the balance of internal and external air pressure.

[0016] Furthermore, the isolation plate is provided with grooves for placing other accessories for the earplugs.

[0017] Therefore, the beneficial effects of this technical solution are as follows: by using a soft shell and soft earplug made of high-elastic rubber, users can manually knead the earplugs to adjust them to a suitable shape according to their own needs, avoiding damage to the earplugs caused by mechanical structures; the manual kneading method allows for better shaping to suit individual needs, fully meeting users' personalized requirements; the sealing strip ensures the airtightness of the internal space of the earplug case, effectively preventing the intrusion of external dust, oil, and other contaminants; and the magnetic cover makes the product more convenient to use.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0027] See Figure 1-4 The purpose of this utility model is to provide an earbud case for manually squeezing earbuds. The earbud case includes a soft outer shell that can hold earbuds 01 and isolate them from the outside environment. The soft outer shell is made of an elastic material that can be easily flattened and kneaded, such as rubber. The interior of the soft outer shell has a storage space that can hold two earbuds separately. Users can squeeze the soft outer shell to deflate the earbuds 01 inside, and the volume of the earbuds 01 after being squeezed varies depending on the force of the user's squeezing. At the same time, the soft outer shell is provided with a cover 2 that can open or close the soft outer shell; the cover 2 can achieve good isolation of the earbuds 01 from the external environment and also facilitates handling.

[0028] Based on the above structure, staff can knead the earplug 01 into a shape suitable for their own use inside the soft shell, according to their own feelings, usage experience, or habits, and then take it out and wear it. This process not only ensures the hygiene of the earplugs but also provides a more humanized user experience that suits their own wearing needs.

[0029] Based on the above concept, the following are specific embodiments that can realize the technical concept: Example

[0030] The earphone case includes a main frame 1 with a certain rigidity, that is, a support function. The main frame 1 is preferably made of plastic. A soft shell 3 (i.e., a soft outer shell) and a rotatable cover 2 are respectively installed at the bottom and top of the main frame 1.

[0031] Specifically, the cover 2 is hinged to the top of the main frame 1. The cover 2 can be rotated to close or open. The connection between the main frame 1 and the soft shell 3 can be adhesive, snap-fit, riveting, or heat-fused, or a combination of these methods. The specific connection method is not limited. In this design, the main frame 1 and the soft shell 3 are fixed using a combination of snap-fit ​​and adhesive. Specifically, the main frame 1 has a groove that snaps into the soft shell 3, and adhesive is applied inside the groove to bond the contact area between the main frame 1 and the soft shell 3.

[0032] The earbud case also contains two soft earbud shells 5, each matching the size and number of the earbuds 01. Specifically, two soft earbud shells 5 are located inside the earbud case. These shells are also made of a soft material, allowing the two earbuds 01 to be placed independently. The soft earbud shells 5 are mounted inside the earbud case via an isolation plate 4 on the main frame 1. The isolation plate 4 is installed on the main frame 1 to isolate the interior of the soft earbud shell 3 from the outside environment. The isolation plate 4 has two symmetrical through holes, through which two soft earbud shells 5 are fixedly connected. The connection method between the soft earbud shells 5 and the isolation plate 4 is similar to the connection method between the main frame 1 and the soft earbud shell 3. In this design, the connection between the soft earbud shells 5 and the isolation plate 4 uses a combination of snap-fit ​​and adhesive bonding.

[0033] Therefore, this embodiment enables the isolated storage and individual use of the two earplugs 01. When stored separately, the user can manually squeeze and knead the earplugs 01 inside the soft shell 5 to shape them to their liking. They can then be directly removed after opening the cover 2. Furthermore, because this product uses highly elastic rubber for the soft shell 5 and soft body 3, they quickly return to their original shape after being kneaded. In contrast, the earplugs 01, typically made of special sound-absorbing or sponge materials, recover their size more slowly. This gap between the earplugs 01 and the soft shell 5 makes them easier to handle.

[0034] Example 1

[0035] This embodiment is a further optimization based on Embodiment 1. In this embodiment:

[0036] The isolation plate 4 is installed on the main frame 1 by snap-fitting. That is, the main frame 1 is provided with a snap-fit ​​groove 12 that matches the shape of the side of the isolation plate 4, and the height of the snap-fit ​​groove 12 is adapted to the thickness of the isolation plate 4. The isolation plate 4 can be snapped into the snap-fit ​​groove 12 by pressing with a certain force, or it can be deformed and released by pushing with a certain force.

[0037] This earbud case is compatible with earbuds 01 of different sizes. Earbuds 01, as a component of this earbud case, come in various sizes to accommodate different users' ear canal sizes. Therefore, this product is designed with various models of isolation plates 4, each containing a different size soft earbud shell 5, to match the different sizes of earbuds 01. Users can choose the appropriate isolation plate 4 for their own earbud 01 size and replace it themselves.

[0038] Preferably, a first magnetic attraction point 10 is provided on the side of the main frame 1 away from the hinge point with the cover 2, and a second magnetic attraction point 20 is provided on the side of the cover 2 away from the hinge point with the main frame 1, corresponding to the first magnetic attraction point 10. The first magnetic attraction point 10 and the second magnetic attraction point 20 can cooperate to attract each other, and can be attracted to each other when they are close together.

[0039] Preferably, a sealing strip 11 is fixedly connected to the top surface of the main frame 1 (the surface near the bottom of the cover 2). The sealing strip 11 can seal the internal space of the earphone box, preventing external dust from entering the interior and further improving the overall sealing performance of the device.

[0040] Preferably, a buckle 14 is fixedly installed on the main frame 1. The buckle 14 is made of elastic plastic, allowing the user to clip the earphone case onto a belt or arm pocket for easier daily carrying. Specifically, a back plate 13 is provided on the back of the main frame 1, and the buckle 14 is fixedly connected to the back plate 13.

[0041] Preferably, the soft shell 3 is provided with a vent 31 for maintaining the balance of internal and external air pressure. When the user kneads the soft shell 3, the air inside the soft shell 3 will be discharged from the vent 31.

[0042] Example 2

[0043] This embodiment proposes a wired earbud structure that matches the earbud case. Furthermore, the structure of the earbud case in Embodiment 1 is further optimized for the wired earbud design. In this embodiment:

[0044] In addition to its own foam plug, the earplug 01 also has a gripping part 02 fixedly connected to its top for easy handling. The gripping part 02 is the part that comes into contact with the user's hand, while the foam plug is the part that enters the ear. This design makes the earplug more hygienic. When the earplug 01 is installed inside the soft plug shell 5, the gripping part 02 protrudes slightly from the soft plug shell 5, that is, the gripping part 02 protrudes and is exposed on the top of the insulating plate 4. The gripping part 02 will not be crushed; it is only used for holding.

[0045] Meanwhile, a connecting line 03 is fixedly connected to the top of the holding part 02, with an earplug 01 connected to each end of the connecting line 03. The connecting line 03 helps to prevent the earplugs from being lost. A pull tab 04 is fixedly connected to the middle of the connecting line 03, which allows the user to easily access both earplugs 01.

[0046] Preferably, the partition plate 4 has a groove located in the middle of the two through holes for storing the connecting wire 03 and the pull-up buckle 04. The groove holds the pull-up buckle 04 and the connecting wire 03. After using the earplugs 01, users typically remove them and wrap the connecting wire 03 around their fingers to keep it neatly stored. At this time, the two earplugs 01 and the connecting wire 03 can be inserted into the soft plug shell 5 and the groove respectively, making it more convenient for staff to retrieve them next time.

[0047] In summary, during actual use, both the soft shell 3 and soft earbud shell 5 of the earbud case are made of highly elastic rubber. Users can manually knead the earbuds 01 to adjust them to a suitable wearing shape, and the soft shell 3 and soft earbud shell 5 can quickly return to their original shape after kneading. Since the earbuds 01 are usually made of special sound-absorbing materials or sponge materials, their recovery speed is relatively slow, thus forming a certain gap between the earbuds 01 and the soft earbud shell 5, which makes it more convenient for users to take out the earbuds 01. Users only need to open the cover 2 and directly pinch the earbuds 01 through the lifting part 02, avoiding direct contact between the hands and the sponge part of the earbuds 01, further improving the hygiene of use. Secondly, the earbud case is designed with multiple models of isolation plates 4, and users can replace different models of isolation plates 4 according to their own needs to adapt to different sizes of earbuds 01 and meet the usage requirements of different ear canal sizes. In addition, the earbud case also has a portable design, with a buckle 14 fixedly installed on the main frame 1, allowing users to clip the earbud case to their belt or pocket for convenient daily carrying. Meanwhile, the cover 2 and the main frame 1 are connected by magnetic attraction points (first magnetic attraction point 10 and second magnetic attraction point 20), making the closing of this product faster, more comfortable, and more sophisticated. In order to further improve the sealing and protection performance, the sealing strip 11 can effectively isolate external dust and contaminants, further ensuring the cleanliness of the earplug 01.

[0048] Therefore, the earplug case of this utility model not only provides a hygienic and convenient way to store and adjust earplugs, but also meets the personalized needs of different users and improves the overall user experience through modular design and multiple functional optimizations.

[0049] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
