Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to an ear cover for headphones. Background Technology
[0002] As the pace of life continues to accelerate, many people choose to relax by listening to music and watching videos during their commute or rest time. At the same time, many people enrich themselves by listening to audiobooks and lectures. In order to ensure audio quality without disturbing others, headphones have become a common choice. As a result, the demand for headphones is growing and has become an indispensable part of our lives.
[0003] A search revealed Chinese patent publication number CN217037420U, which discloses an earphone cover, including an ear canal fitting shell. The bottom of the ear canal fitting shell has a sound outlet channel, and a fixing post is located on the outer side of the sound outlet channel. Several micro-springs are evenly distributed on the outer side of the fixing post. When the ear canal fitting shell is inserted into the ear canal, the micro-springs compress, exerting an elastic force that presses against the ear canal, causing the outer side of the ear canal fitting shell to press against the ear canal. A protective spacer made of rubber is located at the bottom of the fixing post. The rubber itself has a certain elasticity, and the top of the protective spacer has several ventilation slots. This allows it to better cooperate with the micro-springs to fix it inside the ear canal, thus achieving the effect of securing the earphone and preventing it from falling off. To prevent dust from entering the headphones, a filter is installed at the headphone's sound outlet to block dust. However, the headphone's sound outlet and the filter are glued together, and over time, the filter may become damaged, dirty, and clogged, making it inconvenient for users to replace. Therefore, a headphone ear tip is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an ear cover for headphones, which aims to improve the problem that in the prior art, the sound outlet and the filter are installed by adhesive bonding, which leads to the filter becoming damaged, dirty and clogged after long-term use, making it inconvenient to replace.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an earphone cover, comprising a shell and a soft rubber sleeve, wherein a sound tube is connected to the right side of the shell, a fixing ring is fixedly connected to the right side of the outer wall of the sound tube, a first insertion groove is provided on the right side of the fixing ring, and a slot is provided on the upper and lower sides of the outer wall of the fixing ring, a locking plate is slidably connected to the inner wall of the two first insertion grooves, a second insertion groove is provided on the right side of the fixing ring, a top block is slidably connected to the inner wall of the two second insertion grooves, a miniature spring is fixedly connected to the left side of the two top blocks, a plug plate is slidably connected to the inner wall of the two second insertion grooves, a mounting plate is fixedly connected to the right side of the two plug plates, a filter screen is fixedly connected to the inner wall of the mounting plate, and a fastening mechanism is provided on the outer wall of the sound tube.
[0006] The above technical solution involves the fixed ring and the sound tube being integrally formed. The locking plate and the plug-in plate on the mounting plate are plugged into the corresponding plug-in slots one and two. When fully inserted, the locking plate will lock into the slot, thus completing the installation of the filter screen. When disassembly is required, pressing the protrusion on the locking plate will cause the plug-in plate to pop out quickly under the action of the micro spring against the top block, thereby allowing the mounting plate to quickly detach from the plug-in slot two and achieve quick disassembly.
[0007] As a further description of the above technical solution:
[0008] The fastening mechanism includes two U-shaped rings, which are fixedly connected to the inner wall of the soft rubber sleeve. An elastic element is fixedly connected between adjacent U-shaped rings. A fitting ring is fixedly connected to the left side of the outer wall of the soft rubber sleeve. The inner wall of the fitting ring is provided with multiple air holes.
[0009] The above technical solution involves connecting the U-shaped rings with elastic elements, forming a single unit. The U-shaped rings are installed inside the soft rubber sleeve. When the user wears the earphone, the left side of the soft rubber sleeve contracts and is squeezed inward. At this time, under the action of the elastic elements, the left side of the soft rubber sleeve, together with the fitting ring, perfectly fits the ear canal. Meanwhile, the vent can dissipate internal heat, preventing stuffiness.
[0010] As a further description of the above technical solution:

[0012] The above technical solution provides a sealing treatment for the housing and also protects the internal components.
[0013] As a further description of the above technical solution:
[0014] A power switch and a signal receiver are fixedly connected to the left side of the housing.
[0015] Through the above technical solution: the power switch can control the entire device, and the signal receiver can achieve Bluetooth connection to enhance signal reception.
[0016] As a further description of the above technical solution:
[0017] A bottom post is fixedly connected to the bottom of the housing, and a buffer pad is fixedly connected to the bottom end of the bottom post.
[0018] The above technical solution allows the shell and the base to be molded as a single piece, and the base can be positioned while the earphone is charging.
[0019] As a further description of the above technical solution:
[0020] Multiple charging pads are fixedly connected to the bottom of the outer wall of each base column, and the multiple charging pads are arranged at equal intervals.
[0021] Through the above technical solution, the charging pads can perform charging, and the equidistant arrangement of multiple charging pads can enable more precise plug-in power supply.
[0022] As a further description of the above technical solution:
[0023] The bottom wall of the soft rubber sleeve is fixedly connected to a carbon fiber woven mesh, and the bottom wall of the carbon fiber woven mesh is fixedly connected to a silver ion antibacterial agent.
[0024] Through the above technical solution: the carbon fiber woven mesh serves as the middle support structure, which can support the entire earphone cover like a skeleton, allowing it to maintain its original shape when subjected to pressure and bending. The silver ion antibacterial agent, as the inner layer that directly contacts the skin, can continuously inhibit the growth and reproduction of bacteria, reducing the risk of ear infections caused by prolonged earphone use.
[0025] As a further description of the above technical solution:
[0026] The outer wall of the soft rubber sleeve is coated with polyurethane.
[0027] The above technical solution involves using a polyurethane coating, which can block ultraviolet rays from corroding the material itself. Ultraviolet rays are one of the key factors that cause materials to yellow and age. The coating is evenly sprayed onto the outermost layer of the earphone cover to form a thin and tough protective film.
[0028] This utility model has the following beneficial effects:
