[0001] The utility model relates to the field of waterproof plug structures for earphones, in particular to a waterproof rubber plug structure for bluetooth earphones. Background Art

[0002] Bluetooth headsets are an electronic product that is very popular among consumers. Bluetooth headsets also come with a charging box, which is flexible and convenient to wear, and compact and portable. Usually Bluetooth headsets are divided into in-ear and non-in-ear types. In order to get a better hearing experience, the in-ear headset sound mouthpiece has a soft plug, which can fit the ear canal, not only reducing sound leakage, but also being soft and skin-friendly.

[0003] The existing earphone soft plug structure can refer to the patent document with announcement number CN214070159U, which discloses an anti-earwax silicone earplug for a hearing aid, wherein an adjustable dustproof net is provided at the top of the inner wall of the earplug main body, a first earplug is provided at the top of the outer wall of the earplug main body, a second earplug is provided at the bottom of the first earplug, a silicone connecting plate is connected between the bottom end of the first earplug and the top end of the second earplug, a connecting protective cover is provided at the bottom end of the earplug main body, a reinforcing connecting block is provided at the bottom end of the connecting protective cover, and a dustproof net is used. After the earplug main body is taken out of the ear, the rotating cover is rotated through the rotating shaft, the dustproof net is pulled upward, and the card block is disengaged from the card slot, and the dustproof net can be taken out of the inner cavity of the earplug main body for cleaning, which is convenient for cleaning the earwax adhered to the earplug main body.

[0004] If the silicone earplug provided in the above technical solution is applied to a Bluetooth headset, the earplug needs to be removed for cleaning, which is inconvenient. In addition, the gap left between the second earplug and the connecting protective cover is prone to earwax accumulation, further increasing the difficulty of cleaning. Utility Model Content

[0005] In order to reduce earwax accumulation and facilitate cleaning of earphone dirt, the present application provides a waterproof rubber plug structure for Bluetooth earphones.

[0006] The present application provides a waterproof rubber plug structure for a Bluetooth headset using the following technical solution:

[0007] A waterproof rubber plug structure for a Bluetooth headset, comprising:

[0008] An earphone body, wherein a connecting tube is protruding outwardly from the edge of the sound outlet of the earphone body;

[0009] A soft plug, which is elastic and sleeved on the sound outlet of the earphone body, is provided with a mounting hole which is interference-fitted with the connecting tube;

[0010] The charging box comprises a box body and a box cover which are rotatably connected, the box body being used to accommodate the earphone body and the soft plug. In a mating state, one end of the earphone body is inserted into the box body, and one end of the earphone body connected to the soft plug extends out of the box body. A cleaning soft glue is provided on the inner wall of the box cover. The box cover is closed so that the cleaning soft glue is wrapped and fits outside the sound outlet of the soft plug and the earphone body; the box cover is opened so that the cleaning soft glue is disconnected from the earphone body and the soft plug.

[0011] By adopting the above technical solution, a cleaning soft gel is set on the inner side of the box cover. Since the cleaning soft gel is plastic and sticky, when the earphones are stored in the charging box, the cleaning soft gel can be accurately wrapped around the outer periphery of the sound outlet of the earphone body and the outer contour of the soft plug, and when the box cover is opened, it can use its own stickiness to remove the earwax adhered to the sound outlet and the outside of the soft plug. Each time the box cover is opened to take out the earphones, it is equivalent to automatically cleaning the sound outlet and the soft plug. It is easy to operate, and frequent cleaning can prevent dirt from accumulating.

[0012] Furthermore, a convex edge is provided on the peripheral wall of the connecting tube, and a clamping groove which is concave-convexly matched with the convex edge is convexly provided on the side wall of the mounting hole.

[0013] By adopting the above technical solution, the connection between the soft plug and the earphone body can be more stable by arranging a snap-in groove on the side wall of the installation hole of the soft plug and cooperating with the convex and concave edge of the peripheral wall of the connecting tube to prevent the soft plug from falling off and being lost during the process of taking or wearing the earphone.

[0014] Furthermore, the soft plug includes two layers of elastic membranes, which are sealed and connected to form a cavity. The cavity is filled with gas, and the elastic membranes swell and deform under the action of gas pressure.

[0015] By adopting the above technical solution, a cavity is formed between the sealed double-layer elastic membranes, and air is inflated into the cavity. When wearing the earphone, the soft plug enters the ear canal. Under the action of air pressure, the elastic membrane of the soft plug can fit the ear canal more closely, reducing the risk of the earphone falling off and preventing sound leakage, thereby obtaining a better auditory experience. Compared with the existing open soft plugs, sealing the two layers of elastic membranes can also minimize the risk of earwax falling into the interlayer of the soft plug that is difficult to clean.

[0016] Furthermore, a suction cup is provided on the end surface of the soft plug, and the suction cup is attached to the earphone body.

[0017] By adopting the above technical solution, the suction cup is provided to further improve the connection strength between the soft plug and the earphone body, and to avoid the rubber plug from falling off the earphone body during use.

[0018] Furthermore, a rigid protective cover is connected between the suction cup and the soft plug.

[0019] By adopting the above technical solution, since the suction cup and the soft plug are both made of flexible materials, the suction cup is adsorbed on the surface of the earphone body and is difficult to remove, so a rigid protective cover is provided. Pressing the protective cover from both sides can cause the edge of the suction cup to lift up, thereby destroying the negative pressure environment and facilitating taking and placing; touching the protective cover from one side causes the protective cover to move with the deformation of the soft plug, thereby ensuring the adsorption stability of the suction cup and the earphone body under daily use.

[0020] Furthermore, a side of the protective cover facing away from the suction cup is covered with a silicone layer.

[0021] By adopting the above technical solution, laying a silicone layer on the surface of the protective cover can improve skin-friendliness and enhance the user experience. At the same time, the silicone layer also has a waterproof effect.

[0022] Furthermore, the silicone layer is detachably connected to the protective cover.

[0023] By adopting the above technical solution, the silicone layer is easy to wear and tear, and the connection can be removed for easy replacement.

[0024] Furthermore, a Velcro is provided between the silicone layer and the protective cover, and the Velcro includes a sub-sticker and a mother sticker, the sub-sticker is fixedly connected to the silicone layer, the mother sticker is fixedly connected to the protective cover, and the sub-sticker and the mother sticker are bonded to fix the silicone layer and the protective cover.

[0025] By adopting the technical solution, the Velcro is easy to operate.

[0026] Furthermore, the surface of the protective cover is smooth, and an electrostatic film is attached to the side of the silicone layer facing the protective cover, and the electrostatic film is adsorbed on the surface of the protective cover.

[0027] By adopting the above technical solution and using electrostatic film adsorption and fixation, the occupied space can be minimized, making the soft plug more compact and exquisite.

[0028] Furthermore, the outer contour of the soft plug is spindle-shaped.

[0029] By adopting the above technical solution, the spindle-shaped soft plug is more convenient to use.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting a cleaning soft gel on the inside of the box cover, since the cleaning soft gel is plastic and sticky, when the earphones are stored in the charging box, the cleaning soft gel can be accurately wrapped around the outer contour of the sound outlet of the earphone body and the soft plug, and the earwax on the soft plug can be removed by the stickiness of the cleaning soft gel. Each time you open the box cover to take out the earphones, it is equivalent to automatically cleaning the sound outlet and the soft plug. It is easy to operate, and frequent cleaning can prevent dirt from accumulating;

[0032] 2. By making the soft plug into a sealed double-layer elastic membrane and inflating the cavity of the soft plug, when wearing the earphone, the soft plug enters the ear canal. Under the action of air pressure, the elastic membrane of the soft plug can fit the ear canal more closely, reducing the risk of the earphone falling off and preventing sound leakage, thereby obtaining a better listening experience;

[0033] 3. By setting a suction cup on the end surface of the soft plug, the suction cup fits and adsorbs on the earphone body, which further improves the connection strength between the soft plug and the earphone body, and tries to avoid the rubber plug from falling off the earphone body during use.

[0040] The following is combined with Figure 1-4 The technical solution of this application is described clearly and completely.

[0041] Example 1

[0042] The embodiment of the present application discloses a waterproof rubber plug structure for a Bluetooth headset.

[0043] Reference Figure 1 A waterproof rubber plug structure for a Bluetooth headset includes an earphone body 1, a soft plug 2 and a charging box 3. A connecting tube 12 is protruding outward from the sound outlet 11 of the earphone body 1, and a mounting hole 21 is opened on the soft plug 2, which can be interference-fitted with the connecting tube 12. The charging box 3 includes a box body 31 and a box cover 32 connected by a flip cover. The earphone body 1 and the soft plug 2 assembled as one are inserted in the box body 31, and one end of the earphone body 1 with the soft plug 2 protrudes from the box body 31.

[0044] A cleaning soft glue 33 is provided on the inner wall of the box cover 32. When the box cover 32 is closed, the cleaning soft glue 33 can wrap and fit the outer contour of the soft plug 2 and the earphone body 1, so that the cleaning soft glue 33 can adhere to and absorb earwax. Each time the box cover 32 is opened, it is equivalent to cleaning the earphone, which can reduce earwax accumulation and facilitate cleaning of earphone dirt.

[0045] Reference Figure 1 The charging box 3 is arc-shaped all over, which is convenient for gripping and carrying. Two symmetrical receiving grooves 311 are horizontally opened in the box body 31, and a pair of earphone sound outlets 11 are facing upward and inserted in the receiving grooves 311. The cleaning soft glue 33 is fully spread on the inner wall of the box cover 32. The cleaning soft glue 33 is a transparent colloid, mainly made of a mixture of water, guar gum, and glycerin. It is sticky but will not adhere to the surface of smooth objects. Since the cleaning soft glue 33 can be plastically deformed, when the earphone body 1 is replaced with soft plugs 2 of different models and sizes, the box cover 32 is closed, and the cleaning soft glue 33 is squeezed and deformed, and can cover and wrap the outer periphery of the soft plug 2 and the sound outlet 11 and other parts where earwax is easily left. The cleaning soft glue 33 can be reused many times. When too much dirt adheres to the cleaning soft glue 33 and loses its stickiness, it can be removed and replaced with a new cleaning soft glue 33.

[0046] Reference Figure 2-Figure 4 The sound outlet 11 is located on the side of one end of the earphone body 1, the peripheral wall of the connecting tube 12 is provided with an annular convex edge 121, and the side wall of the mounting hole 21 of the soft plug 2 is provided with a snap-in groove 221 that matches the convex edge 121. The convex edge 121 is snapped into the snap-in groove 221 to make the connection between the soft plug 2 and the earphone body 1 more stable, so as to prevent the soft plug 2 from falling off and being lost during the process of taking or wearing the earphone. In this embodiment, the sound outlet 11 is circular, the connecting tube 12 is cylindrical, the convex edge 121 and the snap-in groove 221 are also correspondingly set as circular rings, and the convex edge 121 is provided with two grooves; in other embodiments, the snap-in groove 221 and the convex edge 121 can also be vertical bars or scattered points, and the sound outlet 11 and the connecting tube 12 can also be other shapes such as elliptical or waist-shaped holes.

[0047] Reference Figure 2 The outer contour of the soft plug 2 is spindle-shaped, including two layers of elastic membranes 22, which are sealed and connected. The elastic membranes 22 are preferably made of rubber or silicone. The two layers of elastic membranes 22 enclose a cavity 23, which is filled with an inert gas. The elastic membrane 22 bulges and deforms under the action of air pressure. When wearing headphones, the soft plug 2 enters the ear canal. Under the action of air pressure, the elastic membrane 22 of the soft plug 2 can fit more closely to the ear canal, reducing the risk of the headphones falling off and preventing sound leakage, thereby obtaining a better auditory experience. Compared with the existing open soft plug 2, sealing the two layers of elastic membranes 22 can also minimize the risk of earwax falling into the interlayer of the soft plug 2 that is difficult to clean.

[0048] Reference Figure 3, a suction cup 24 is provided at one end of the soft plug 2 close to the earphone body 1, and the suction cup 24 fits the earphone body 1. Since the earphone body 1 is mostly an arc-shaped contour, the suction cup 24 can fit the surface of the earphone body 1, and the connection strength between the soft plug 2 and the earphone body 1 is enhanced by negative pressure, so as to avoid the rubber plug from falling off the earphone body 1 during use. Since the suction cup 24 and the soft plug 2 are both flexible materials, the suction cup 24 is adsorbed on the surface of the earphone body 1 and is difficult to remove, so a rigid protective cover 25 can be installed between the suction cup 24 and the soft plug 2. One end of the protective cover 25 is fixed to the elastic membrane 22, and the other end is fixed to the suction cup 24. Pressing the protective cover 25 from both sides of the soft plug 2 can make the edge of the suction cup 24 tilt up, thereby destroying the negative pressure environment of the suction cup 24, and facilitating the lowering of the soft plug 2 from the connecting tube 12; and if the protective cover 25 is only touched from one side, the protective cover 25 will move with the deformation of the elastic membrane 22, thereby ensuring the adsorption stability of the suction cup 24 and the earphone body 1 under daily use.

[0049] Reference Figure 3 , Figure 4 The side of the protective cover 25 facing away from the suction cup 24 is covered with a silicone layer 26, and the silicone layer 26 is detachably connected to the protective cover 25. The silicone layer 26 can improve the skin-friendly feeling and enhance the user experience. At the same time, the silicone layer 26 also has a waterproof effect. In this embodiment, a Velcro is provided between the silicone layer 26 and the protective cover 25. The Velcro includes a sub-strip and a mother-strip. The sub-strip is fixedly connected to the silicone layer 26, and the mother-strip is fixedly connected to the protective cover 25. The sub-strip and the mother-strip are bonded to fix the silicone layer 26 and the protective cover 25. Silicone is easy to wear out after long-term use. It is convenient to remove the silicone layer 26 using Velcro, and the cost is low. The silicone layer 26 of different colors can also be replaced to give it an additional decorative effect.

[0050] Example 2

[0051] The difference between Example 2 and Example 1 is that the connection and fixing method between the silicone layer 26 and the protective cover 25 is different.

[0052] In this embodiment, a smooth material is selected to make the protective cover 25, and an electrostatic film is attached to the side of the silicone layer 26 facing the protective cover 25, and the electrostatic film is adsorbed on the surface of the protective cover 25. Using the electrostatic film to adsorb and fix the silicone layer 26 can minimize the occupied space, making the soft plug 2 more compact and delicate.

[0053] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the protection scope of the present application.
