Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass films, specifically a tempered glass film for dustproofing earpieces. Background Technology

[0002] Tempered glass screen protectors are special glass films used to protect the screens of electronic devices. They are characterized by high strength, scratch resistance, and impact resistance. They are created by chemical or physical methods to form compressive stress on the glass surface, thereby improving load-bearing capacity and enhancing resistance to wind pressure, temperature changes, and impacts. Tempered glass screen protectors have high hardness, effectively preventing scratches from sharp objects, while also possessing good drop resistance. Furthermore, they maintain a light transmittance of up to 98%, without affecting the screen's display quality.

[0003] According to Chinese Patent No. CN216217018U, a tempered glass screen protector with an edge earpiece dustproof mesh includes a glass layer, an adhesive layer, and a dustproof mesh. The glass layer has an upper surface and a lower surface, the adhesive layer has an upper adhesive surface and a lower adhesive surface, and the dustproof mesh has an upper dustproof surface and a lower dustproof surface. The upper adhesive surface of the adhesive layer is attached to the lower surface of the glass layer. The top edge of the glass layer is recessed inward to completely cover the earpiece of the mobile phone. A portion of the dustproof mesh is embedded in the recess and attached to the upper adhesive surface of the adhesive layer. Another portion of the dustproof mesh protrudes from the top edge of the glass layer. The adhesive layer has a sound transmission hole corresponding to the recess of the glass layer.

[0004] In the above solution, a dustproof net is used to isolate dust by being pasted onto the adhesive layer. However, this solution still has the following drawbacks: since the dustproof net is pasted onto the adhesive layer, dust may accumulate on the net over time, forcing the replacement of the original tempered glass screen protector and reducing its lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a tempered glass screen protector for earpieces, in order to solve the problem that dust may accumulate on the screen protector over time, forcing the replacement of the original tempered glass screen protector and reducing its service life.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a tempered glass diaphragm for earpiece dustproofing, including an earpiece hole, the earpiece hole being opened on the top surface of the tempered glass diaphragm body, an installation frame being detachably provided on the inner wall of the earpiece hole, two dustproof sheets being fixed inside the installation frame, positioning grooves being respectively opened on both sides of the inner side of the earpiece hole, and positioning plates being respectively fixed on both sides of the installation frame, the positioning grooves and positioning plates being interference fit.

[0007] Preferably, the bottom surface of the positioning plate is fixed with several reinforcing plates, and several reinforcing grooves are respectively opened on both sides of the inside of the earpiece hole, and the reinforcing plates and the reinforcing grooves are interference fit.

[0008] Preferably, the top surface of the tempered glass film body is provided with a camera hole, a cleaning column is rotatably arranged inside the camera hole, a rotating disk is fixed at the top of the cleaning column, and a rotating bar is fixed on the top surface of the rotating disk.

[0009] Preferably, an adhesive layer is fixed to the bottom surface of the tempered glass film body.

[0010] Preferably, the tempered glass film body has arc-shaped edges on all four sides.

[0011] Preferably, the four corners of the tempered glass film body are each provided with an obtuse angle.

[0012] Compared with existing technologies, a tempered glass diaphragm for earpiece dust prevention using the above-mentioned technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. After the user attaches the tempered glass screen protector to the surface of the phone screen, the earpiece hole overlaps with the earpiece. The user then installs the mounting frame into the earpiece hole, and moves the positioning plate into the positioning groove for an interference fit. During this process, the reinforcing plate is moved into the reinforcing groove for an interference fit, increasing the stability of the mounting frame inside the earpiece hole. After the mounting frame is fixed inside the earpiece hole, the dustproof sheet fixed inside the mounting frame is above the earpiece. The dustproof sheet is made of nanofiber material, which can prevent dust from clogging the earpiece. When a lot of dust adheres to the dustproof sheet and affects the sound reception, the user can use the SIM card ejector tool to pick the mounting frame out of the earpiece hole and replace it, thereby increasing the service life of the tempered glass screen protector.

[0015] 2. As the usage time increases, a lot of dust may accumulate at the contact point between the bottom of the camera hole and the phone screen. At this time, the user can take out the cleaning stick from the tempered glass screen protector packaging box, put it inside the camera hole, and use the rotating strip to drive the cleaning stick to rotate, which can clean the dust inside the camera hole and prevent dust from interfering with the clarity of the phone camera.

[0016] Third, when the user applies the tempered glass screen protector to the phone screen, the adhesive layer on the bottom of the screen protector increases its firmness on the phone screen. At the same time, because the four sides and four corners of the screen protector are respectively made into curved edges and obtuse angles, the rounded edges and obtuse angles can prevent scratches to the user's palms, increasing the safety of the screen protector during use.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, a tempered glass diaphragm for earpiece dustproofing includes an earpiece hole 2, which is opened on the top surface of the tempered glass diaphragm body 1. An installation frame 3 is detachably provided on the inner wall of the earpiece hole 2. Two dustproof sheets 4 are fixed inside the installation frame 3. Positioning grooves 5 are respectively opened on both sides of the inner side of the earpiece hole 2. Positioning plates 6 are respectively fixed on both sides of the installation frame 3. The positioning grooves 5 and the positioning plates 6 are interference-fitted. Several reinforcing plates 8 are fixed on the bottom surface of the positioning plates 6. Several reinforcing grooves 7 are respectively opened on both sides of the inner side of the earpiece hole 2. The reinforcing plates 8 and the reinforcing grooves 7 are interference-fitted.

[0024] During use, after the user attaches the tempered glass screen protector 1 to the surface of the phone screen, the earpiece hole 2 overlaps with the earpiece. The user then installs the mounting frame 3 into the earpiece hole 2, and moves the positioning plate 6 into the positioning groove 5 for an interference fit. During this process, the reinforcing plate 8 is moved into the reinforcing groove 7 for an interference fit, increasing the stability of the mounting frame 3 inside the earpiece hole 2. After the mounting frame 3 is fixed inside the earpiece hole 2, the dustproof sheet 4 fixed inside the mounting frame 3 is positioned above the earpiece. The dustproof sheet is made of nanofiber material, which can prevent dust from clogging the earpiece. When a large amount of dust adheres to the dustproof sheet 4 and affects the sound reception, the user can use a SIM card ejector tool to remove the mounting frame 3 from inside the earpiece hole 2 and replace it, thereby increasing the service life of the tempered glass screen protector.

[0025] like Figure 2 and Figure 4As shown, a camera hole 9 is provided on the top surface of the tempered glass film body 1. A cleaning column 10 is rotatably arranged inside the camera hole 9.
