[0030] In one embodiment of the utility model, as shown in Figures 1-4 As shown, a dustproof Bluetooth speaker is provided, which comprises an upper shell 10 and a lower shell 20.The upper shell 10 is internally provided with detachably connected dustproof nets 11 on both sides.The outer side of the upper shell 10 is provided with fixed grooves 12 at both ends.The fixed grooves 12 are provided with clamping blocks 13.The outer side of the lower shell 20 is provided with fixed blocks 21 corresponding to the fixed grooves 12 at both ends.The fixed blocks 21 are provided with ejection assemblies 30 corresponding to the clamping blocks 13.The dustproof nets 11 and the upper shell 10 are provided with quick release assemblies 40 for quick release.The dustproof nets 11 and the upper shell 10 are provided with positioning assemblies 50 for quick positioning.

[0031] By setting the dust screen 11, the dust from the outside is effectively blocked from entering the inside of the sound box, reducing the accumulation of dust inside the sound box, so that the heat inside the sound box can be smoothly discharged, thereby improving the heat dissipation efficiency, and further by setting the quick release assembly 40, the inside of the upper shell 10 is detachably connected with the dust screen 11, making the disassembly and installation of the dust screen 11 very convenient, and the user can disassemble the dust screen 11 at any time according to the need for cleaning, further reducing the accumulation of dust outside the dust screen 11, thereby improving the heat dissipation efficiency and prolonging the service life of the sound box.

[0032] Preferably, the dust screen 11 is provided with a fixed portion 111 extending outward at both ends. The quick release assembly 40 includes a connecting rod 41 and a connecting portion 42. The connecting rod 41 is fixedly connected to the fixed portion 111. The connecting portion 42 is provided on the connecting rod 41, and the connecting portion 42 is tightly connected with the upper shell 10. By setting the connecting portion 42 and the connecting rod 41, the connecting portion 42 is tightly connected with the upper shell 10, which not only improves the convenience of disassembly and installation of the dust screen 11, but also ensures the stability of the dust screen 11 during use, avoiding the problem of blocked heat dissipation channel caused by loose or misaligned dust screen 11, further ensuring the heat dissipation performance of the sound box.

[0033] Further, the connecting portion 42 is a circular or wedge-shaped rubber block. The connecting portion 42 and the connecting rod 41 are connected by screws. In this embodiment, the connecting portion 42 is made of rubber block material, which can be tightly fixed to the upper shell 10 due to the elasticity of the rubber block. The connecting portion 42 and the connecting rod 41 are connected by screws, which can stably connect the two without falling off.

[0034] Specifically, the positioning assembly 50 includes a plurality of positioning columns 51 distributed at equal intervals. The plurality of positioning columns 51 are fixedly connected to the upper shell 10. The fixed portion 111 is provided with a plurality of positioning holes 52 corresponding to the positioning columns 51, and the positioning columns 51 can enter or disengage from the positioning holes 52. By setting the positioning columns 51 and the positioning holes 52, the dust screen 11 can be easily fixed to the mounting position of the upper shell 10, improving the installation efficiency of the dust screen 11.

[0035] Preferably, the dust screen 11 is provided with a dust-proof layer 112 on the outside for preventing dust adhesion, and the dust-proof layer 112 is made of high molecular material. By setting the dust-proof layer 112, the adhesion of fine dust particles on the dust screen 11 is effectively prevented, reducing the possibility of dust accumulation, thereby prolonging the cleaning cycle of the dust screen 11 and reducing the cost and difficulty of user maintenance. At the same time, the dust-proof layer 112 is made of high molecular material, such as synthetic resin, which ensures the durability and stability of the dust-proof layer 112 and improves the overall service life of the sound box.

[0036] Preferably, the clamping block 13 comprises a first reset spring 131 and a clamping portion 132. The clamping portion 132 is slidingly connected in the lower shell 20. One end of the first reset spring 131 is fixedly connected to the lower shell 20, and the other end is fixedly connected to the clamping portion 132, and the first reset spring 131 is located between the clamping portion 132 and the lower shell 20. A clamping groove is provided between the clamping portion 132 and the fixed block 21. When the fixed block 21 and the fixed groove 12 abut each other, the clamping portion 132 extends into the clamping groove of the fixed block 21 under the action of the first reset spring 131, thereby stably connecting the lower shell 20 to the upper shell 10, and preventing dust from entering the Bluetooth speaker from the gap between the two.

[0037] Specifically, the ejection assembly 30 comprises an ejection button 31 and two sets of symmetrically distributed ejector rods 32. The ejection button 31 is movably arranged on one side of the fixed block 21, and a second reset spring 33 is arranged between the ejection button 31 and the fixed block 21. The ends of the two sets of ejector rods 32 are arranged at the ends of the ejection button 31 and abut the ends of the ejection button 31. The head ends of the ejector rods 32 abut the clamping portion 132. When the dust screen 11 needs to be replaced, the ejection button 31 is pressed, the bottom end of the ejection button 31 pushes the ends of the two sets of ejector rods 32 to move outward respectively, and then the head ends of the ejector rods 32 push the clamping portion 132 out of the clamping hole of the fixed block 21, thereby releasing the clamping of the clamping portion 132 on the fixed block 21, so that the user can take out the upper shell 10 from the lower shell 20, and replace or disassemble the dust screen 11 in the upper shell 10.

[0038] Further, the bottom end of the ejection button 31 has a V-shaped portion. The end of the ejector rod 32 has a slope corresponding to the V-shaped portion. By arranging the V-shaped portion and the slope, the ejection button 31 can more smoothly push the ejector rod 32 when it is stressed, thereby more effectively ejecting the clamping block 13, and achieving easy disassembly between the upper shell 10 and the lower shell 20, which helps users to operate the speaker more efficiently during cleaning and maintenance, and reduces the additional time and energy consumption caused by difficult disassembly.

[0039] Preferably, the upper shell 10 is provided with a handle 14 and a plurality of function keys 15. The plurality of function keys 15 are equally spaced at the top end of the upper shell 10 and located on one side of the handle 14. By arranging the handle 14, the user can conveniently carry and move the speaker, and at the same time, it is also convenient for the user to easily take out the upper shell 10 from the lower shell 20 when disassembling the upper shell 10 and the lower shell 20, thereby simplifying the steps of taking out the upper shell 10.

[0040] In this embodiment, the plurality of function keys 15 include a power key, a Bluetooth key, a pause start key, a volume down key, a volume up key and a mode key. The user controls the keys according to the use requirements, thereby realizing the corresponding functions.

[0041] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment. Any simple modification, equivalent change and modification of the above embodiment according to the present application are within the scope of the technical solution of the present application.
