[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] The utility model solves the problem that the existing dustproof net and the speaker housing are connected by bolts, and when disassembling, the bolts need to be screwed in sequence, and the dustproof net can be disassembled only after the bolts are removed, which leads to inconvenient disassembly and cleaning. The dustproof net 3 can be conveniently disassembled and assembled by rotating the fixing block 4, and discloses:

[0033] The headband 1 has earcups 2 attached to its bottom; it further includes: a dust-proof net 3 is contained inside the headband 1, and the inner wall of the dust-proof net 3 is attached to the outside of the earcup 2, and a fixing block 4 is fixed to the outer end of the dust-proof net 3. The outer end of the fixing block 4 extends into the inside of a limiting groove 5 to form a clamping mechanism, and the limiting groove 5 is opened inside the headband 1;

[0034] Reference Figures 2 to 7 , by rotating the dust-proof net 3, the rotation of the dust-proof net 3 drives the fixing block 4 to rotate, and then the fixing block 4 can slide within the limiting groove 5. After the dust-proof net 3 rotates to a certain position, the fixing block 4 will disengage from the clamping of the limiting groove 5. Then, by pulling the dust-proof net 3, the dust-proof net 3 can drive the fixing block 4 to disengage from the limiting groove 5, and then the dust-proof net 3 can be quickly disassembled, so as to facilitate the cleaning of the dust inside the headband 1. And by reversing the above operations, the dust-proof net 3 can be quickly fixed inside the headband 1, thus achieving convenient operation;

[0035] Embodiment Two:

[0036] The present utility model solves the problem that the clamping between the fixing block 4 and the limiting groove 5 in Embodiment One is not stable enough. The clamping stability between the fixing block 4 and the limiting groove 5 can be improved through the clamping between a clamping block 6 and a clamping groove 7, and it discloses:

[0037] A clamping block 6 slides at the bottom of the headband 1, and the inner end of the clamping block 6 is semicircular in shape. The inner end of the clamping block 6 extends into the inside of the clamping groove 7 to form a clamping mechanism, and the clamping groove 7 is opened inside the fixing block 4. The outer end of the clamping block 6 is connected to a first spring 8, and the outer end of the first spring 8 is connected inside the headband 1;

[0038] Reference Figures 2 to 7 , during the rotation of the fixing block 4, the clamping groove 7 will be driven to rotate, and then the rotation of the clamping groove 7 will cause extrusion with the clamping block 6, so that the clamping block 6 is extruded and slides towards the inside of the headband 1, and the sliding of the clamping block 6 will compress the first spring 8, so that the first spring 8 is compressed under force. Then, when the clamping block 6 moves, it will disengage from the clamping of the clamping groove 7. The force of the first spring 8 can push the clamping block 6 into the inside of the clamping groove 7 to form a clamping, so as to improve the clamping stability of the fixing block 4 inside the limiting groove 5;

[0039] Embodiment Three:

[0040] The present utility model solves the problem that the existing earcups 2 are usually fixed to the headband 1 through an elastic tightening layer, which makes the disassembly and assembly not convenient enough. The disassembly and assembly of the earcups 2 can be facilitated through the movement of a convex block 9, and it discloses:

[0041] A bump 9 slides on the outer side of the earcup 2, and the outer side of the bump 9 is arc-shaped. The outer end of the bump 9 extends into the inside of the groove 12 to form a latching mechanism. The groove 12 is opened inside the headband 1. The outer end of the bump 9 is fitted with the inner end of the ejector rod 11, and the ejector rod 11 slides on the side of the headband 1. The inner end of the ejector rod 11 penetrates through the inside of the groove 12. The inner end of the bump 9 is connected with a second spring 10, and the inner end of the second spring 10 is connected inside the earcup 2;

[0042] Reference Figures 1 to 4 , by pressing the ejector rod 11, the ejector rod 11 can extend into the inside of the groove 12 to push the bump 9 to move. Then, when the bump 9 moves, it will extend into the inside of the earcup 2. Then, when the bump 9 moves, it will squeeze the second spring 10, so that the second spring 10 is compressed under force. And when the bump 9 moves, it will disengage from the latching of the groove 12. Then, pull the earcup 2, so that the earcup 2 can be disengaged from the latching of the headband 1, so as to achieve the purpose of disassembling the earcup 2. And by pressing the earcup 2, the earcup 2 can extend into the inside of the headband 1. Then, when the earcup 2 moves, it will drive the bump 9 to move. Then, when the bump 9 moves, it will form a squeeze with the headband 1. Then, the bump 9 is squeezed and moves into the inside of the earcup 2. After moving to the position, the force of the second spring 10 can drive the bump 9 to extend into the inside of the groove 12 to form a latching, so that the earcup 2 can be quickly fixed on the headband 1, so that the earcup 2 can be quickly and conveniently replaced.

[0043] Working principle: When using this kind of easy-to-clean Bluetooth headset, first, reference Figures 2 to 7 , by rotating the dust-proof net 3, the rotation of the dust-proof net 3 drives the fixed block 4 to rotate. After the dust-proof net 3 rotates to the position, the fixed block 4 will disengage from the latching of the limit slot 5. Then, pull the dust-proof net 3, so that the dust-proof net 3 can drive the fixed block 4 to disengage from the limit slot 5. And by reversing the above operations, the dust-proof net 3 can be quickly fixed inside the headband 1, so as to achieve convenient operation;

[0044] Reference Figures 2 to 7 , when the fixed block 4 rotates, it will drive the card slot 7 to rotate. Then, when the card slot 7 rotates, it will cause a squeeze with the card block 6. Then, when the card block 6 moves, it will disengage from the latching of the card slot 7. The force of the first spring 8 can push the card block 6 into the inside of the card slot 7 to form a latching, so as to improve the stability of the fixed block 4 latched inside the limit slot 5;

[0045] Reference Figures 1 to 4, by pressing the ejector rod 11, the ejector rod 11 can extend into the inside of the groove 12 to push the convex block 9 to move. Subsequently, the movement of the convex block 9 will extend into the inside of the earcup 2, and the movement of the convex block 9 will disengage from the engagement with the groove 12. Then, pull the earcup 2, so that the earcup 2 can disengage from the engagement with the headband 1. And by pressing the earcup 2, the earcup 2 can extend into the inside of the headband 1. Then, the movement of the earcup 2 will drive the convex block 9 to move. Subsequently, the movement of the convex block 9 will form a squeeze with the headband 1. After moving to the position, the force of the second spring 10 can drive the convex block 9 to extend into the inside of the groove 12 to form an engagement, so that the earcup 2 can be quickly fixed on the headband 1, and thus the earcup 2 can be quickly and conveniently replaced.
