Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker technology, specifically a Bluetooth speaker with dustproof function. Background Technology

[0002] Bluetooth speakers are audio devices with built-in Bluetooth chips that use Bluetooth connectivity instead of traditional wired connections. They connect to Bluetooth playback devices such as mobile phones, tablets, and laptops for convenient and quick playback. Bluetooth speakers are primarily portable, generally small and easy to carry. Bluetooth speaker technology has gradually gained attention and acceptance from consumers due to its user-friendly features.

[0003] Currently, patent publication number CN218183468U proposes a magnetic charging Bluetooth speaker with heat dissipation function. This speaker includes an outer casing, a rear cover, a front cover, a wireless charging device, an internal speaker component structure, and a heat dissipation device. The front and rear covers are respectively connected to the outer casing by snap-fit ​​connections. A first mounting plate is embedded inside the outer casing, and one end of the first mounting plate houses the internal speaker component structure. This internal component structure is the main body of the speaker device, and its internal components are essentially the same as those in existing speaker device component structures. This allows for Bluetooth connection to mobile phones, tablets, and other devices, and the playback of received audio information. A heat dissipation device is located at the other end of the first mounting plate. This device not only dissipates heat from the inside of the speaker but also from magnetically attached mobile phones, tablets, and other devices. A wireless charging device is located at the other end of the heat dissipation device. This wireless charging device uses existing wireless charging technology and can wirelessly charge magnetically attached mobile phones, tablets, and other devices. In other words, the Bluetooth speaker in this device can be used as a portable power bank. The other end of the wireless charging device is located on one side of the rear cover.

[0004] With the above settings, the existing technical solution can create a flow channel between the phone's back cover, Bluetooth speaker, and internal components during the phone charging process. The airflow within the flow channel carries away the heat generated by the phone's back cover and wireless charging device, improving the heat dissipation of the phone and Bluetooth speaker and preventing the phone from overheating and causing lag.

[0005] However, the existing technical solutions still have the following drawbacks in operation:

[0006] In existing technical solutions, several air vents are provided on the outer wall of the outer casing, and several guide grooves are provided radially on one side of the outer end of the rear cover. Several guide holes are provided in the guide grooves. However, when the Bluetooth speaker is not in use, external dust can easily enter the interior of the Bluetooth speaker through the air vents and guide holes. Long-term accumulation of dust will block the air vents and internal air ducts, hindering air circulation and affecting heat dissipation. Long-term overheating will accelerate the aging of internal components, and conductive particles in the dust can also cause short circuits. Especially in humid environments, dust absorbs moisture and corrodes the circuits and solder joints, causing damage to the Bluetooth speaker. Utility Model Content

[0007] This utility model aims to provide a Bluetooth speaker with a dustproof function, mainly to solve the problem that in the existing technology, when the Bluetooth speaker is not in use, external dust can easily enter the interior of the Bluetooth speaker through the air outlet and air guide hole. Long-term accumulation of dust will block the air outlet and internal air duct, hindering air circulation and affecting heat dissipation. Long-term overheating will accelerate the aging of internal components, and conductive particles in the dust can also cause short circuits.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A Bluetooth speaker with dustproof function includes a Bluetooth speaker shell and an upper cover and a lower cover on the Bluetooth speaker shell. A centrifugal fan is installed inside the Bluetooth speaker shell. The Bluetooth speaker shell has heat dissipation holes. A guide hole is opened on the lower end face of the lower cover. A first protective cover and a second protective cover are slidably connected to the outer wall of the Bluetooth speaker shell. A connecting rod is fixedly connected between the first protective cover and the second protective cover. A dustproof net is fixedly connected between the first protective cover and the second protective cover. A receiving groove is opened on the inner wall of the first protective cover. A limiting component for restricting the movement of the first protective cover and the second protective cover is provided on the inner wall of the receiving groove.

[0010] The working principle and beneficial effects of this utility model:

[0011] 1. Working Principle: When using the Bluetooth speaker, the drive limiting component removes the restriction of the first protective cover on the Bluetooth speaker shell. Then, the first protective cover slides, causing the connecting rod to move along the Bluetooth speaker. The connecting rod then causes the second protective cover to move along the Bluetooth speaker. Simultaneously, the first and second protective covers move the dustproof mesh synchronously. The limiting component moves synchronously with the first protective cover. When the limiting component is released from the pressure of the Bluetooth speaker shell, it abuts against the lower end face of the lower cover of the Bluetooth speaker shell, lifting the Bluetooth speaker. When not using the Bluetooth speaker to play music or to charge a mobile phone, (the magnetic ring allows the Bluetooth speaker to be magnetically attached to the end cover of a mobile phone or the rear cover of a tablet, etc., after which the magnetic coil emits outwards). Magnetic energy is received by devices such as mobile phones and tablets through a charging magnetic induction receiving coil, and then converted into current and voltage to charge the mobile phone or tablet battery. (The part in parentheses refers to the prior art cited in patent publication number CN218183468U, which is not described in detail in this application document.) The limiting component is driven again, causing the limiting component to detach from the lower cover. Then, the first protective cover is driven to move the connecting rod upward along the outer wall of the Bluetooth speaker. At the same time, the connecting rod moves the second protective cover upward. Then, the limiting component is driven to clamp the Bluetooth speaker shell. At this time, the first and second protective covers cannot move. The dustproof net covers the heat dissipation holes opened in the Bluetooth speaker shell. When the Bluetooth speaker is placed on the table, the sealing ring fixed to the lower end face of the second protective cover prevents dust from entering the guide hole.

[0012] 2. Beneficial effects:

[0013] (1) In the prior art, during the charging process of a mobile phone, a heat dissipation device can form a flow channel between the back cover of the mobile phone, the Bluetooth speaker, and the internal components. The air flow in the flow channel carries away the heat generated by the back cover of the mobile phone and the wireless charging device, improving the heat dissipation effect of the mobile phone and the Bluetooth speaker and preventing the mobile phone from overheating and causing lag. However, when the Bluetooth speaker is not in use, external dust can easily enter the interior of the Bluetooth speaker through the air outlet and the air guide hole. Long-term accumulation of dust will block the air outlet and the internal air duct, hindering air circulation and affecting the heat dissipation effect. Long-term overheating will accelerate the aging of internal components. This solution uses the combined use of a first protective cover, a second protective cover, a connecting rod, a dustproof net, a sealing ring, and a limiting component. When the Bluetooth speaker is not in use, the dustproof net prevents dust from entering the air outlet, and the sealing ring prevents dust from entering the air guide hole on the lower cover. This solves the technical problem that external dust can easily enter the interior of the Bluetooth speaker through the air outlet and the air guide hole, and that long-term accumulation of dust will block the air outlet and the internal air duct, hindering air circulation and affecting the heat dissipation effect. Long-term overheating will also accelerate the aging of internal components.

[0014] (2) When the Bluetooth speaker is not used to play music and dust protection is required for the heat dissipation holes, the limiting block is driven to rotate by the drive ring to disengage from the support of the Bluetooth speaker. Then, the first protective cover, connecting rod, dustproof net and second protective cover are moved up along the outer wall of the Bluetooth speaker. When the dustproof net is aligned with the heat dissipation holes and the lower end face of the sealing ring is aligned with the lower end face of the lower cover, the restriction on the limiting block is removed. The limiting block is automatically rotated under the drive of the spring shaft to clamp and fix the outer shell of the Bluetooth speaker. The first protective cover, dustproof net and second protective cover will not move, maintaining the dustproof state of the heat dissipation holes and the guide holes.

[0015] Preferably, the limiting component includes a plurality of clearance grooves formed on the inner wall of the receiving groove. The inner wall of each clearance groove is rotatably connected to a limiting block via a spring shaft. The outer wall of the first protective cover has an annular groove communicating with the clearance grooves. A driving ring is slidably connected within the annular groove. A rack plate is fixedly connected to the inner wall of the driving ring. One end of the limiting block has a toothed groove that meshes with the rack plate. Because the rack plate fixed to the inner wall of the driving ring meshes with the toothed groove at one end of the limiting block, rotating the driving ring drives the rack plate to move... The movement drives the limiting block to rotate around the axis of the spring shaft, disengaging it from the clamping or support of the Bluetooth speaker housing. When the first protective cover moves to the desired position, the rotational force on the drive ring is released. Since the limiting block is rotatably connected to the inner wall of the clearance groove through the spring shaft, the limiting block is freed from the restriction of the drive ring and automatically rotates back under the spring restoring force of the spring shaft to clamp the Bluetooth speaker housing, thereby limiting the first protective cover and preventing the first protective cover, dustproof net, and second protective cover from sliding, which would result in poor dustproof effect.

[0016] Preferably, the outer wall of the Bluetooth speaker housing is symmetrically provided with guide grooves, and the inner wall of the annular groove is fixedly connected to a guide block that cooperates with the guide groove; through the cooperation of the guide block and the guide groove, the first protective cover can be prevented from detaching from the Bluetooth speaker housing, thereby ensuring that the connecting rod, dustproof net, second protective cover, and sealing ring do not detach from the Bluetooth speaker.

[0017] Preferably, the rack plate is located in the clearance groove; one side of the rack plate is fixedly connected to the inner wall of the drive ring, and the other end is located in the clearance groove, ensuring that the rack plate is always engaged with the toothed groove opened at one end of the limiting block and will not be misaligned.

[0018] Preferably, the outer wall of the drive ring is provided with anti-slip grooves; this increases the friction between the hand and the drive ring, making it easier for the hand to rotate the drive ring without slipping.

[0019] Preferably, a rubber pad is fixed to the end of the limiting block away from the drive ring; this increases the friction between the limiting block and the Bluetooth speaker, ensuring that the first protective cover, the second protective cover, and the dustproof net will not slide and affect the dustproof effect on the heat dissipation holes.

[0020] Preferably, the dustproof mesh is horizontally aligned with the heat dissipation holes on the Bluetooth speaker housing; when the Bluetooth speaker is not used to play music but is needed to charge the mobile phone, it can ensure dust protection without affecting heat dissipation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-9 A Bluetooth speaker with dustproof function is shown, including a Bluetooth speaker shell 1 and an upper cover 2 and a lower cover 3 on the Bluetooth speaker shell 1. A centrifugal fan 4 is provided inside the Bluetooth speaker shell 1. The Bluetooth speaker shell 1 has heat dissipation holes 6. The lower cover 3 has a guide hole 7. The feature is that a first protective cover 8 and a second protective cover 9 are slidably connected to the outer wall of the Bluetooth speaker shell 1. A connecting rod 10 is fixedly connected between the first protective cover 8 and the second protective cover 9. A dustproof net 11 is fixedly connected between the first protective cover 8 and the second protective cover 9. The dustproof net 11 is horizontally aligned with the heat dissipation holes 6 on the Bluetooth speaker shell 1. The outer wall of the Bluetooth speaker shell 1 has symmetrically opened guide grooves 13. The inner wall of the receiving groove 12 is fixedly connected to a guide block 14 that cooperates with the guide groove 13. A sealing ring 5 is fixedly connected to the lower end face of the second protective cover 9. The inner wall of the first protective cover 8 has a receiving groove 12. The inner wall of the receiving groove 12 is provided with a limiting component for restricting the movement of the first protective cover 8 and the second protective cover 9.

[0033] The limiting assembly includes several clearance grooves 15 formed on the inner wall of the receiving groove 12. A limiting block 16 is rotatably connected to the inner wall of each clearance groove 15 via a spring shaft. A rubber pad 22 is fixedly attached to the end of the limiting block 16 away from the drive ring 18. An annular groove 17 communicating with the clearance grooves 15 is formed on the outer wall of the first protective cover 8. The drive ring 18 is slidably connected within the annular groove 17. An anti-slip groove 21 is formed on the outer wall of the drive ring 18. A rack plate 19 is fixedly attached to the inner wall of the drive ring 18. The rack plate 19 is located within the clearance grooves 15, with one side of the rack plate 19 fixedly attached to the inner wall of the drive ring 18 and the other end located within the clearance grooves 15, ensuring that the rack plate 19 is always engaged with the toothed groove 20 at one end of the limiting block 16 and will not misalign. One end of the limiting block 16... A toothed groove 20 is provided, which meshes with a rack plate 19. Since the rack plate 19, which is fixed to the inner wall of the drive ring 18, meshes with the toothed groove 20 at one end of the limiting block 16, the drive ring 18 can drive the rack plate 19 to move, thereby driving the limiting block 16 to rotate around the axis of the spring shaft to disengage from the clamping or support of the Bluetooth speaker shell 1, thus canceling the rotational force on the drive ring 18. Since the limiting block 16 is rotatably connected to the inner wall of the clearance groove 15 through the spring shaft, the limiting block 16 is freed from the restriction of the drive ring 18 and automatically rotates under the spring restoring force of the spring shaft to clamp the Bluetooth speaker shell 1, thereby limiting the first protective cover 8 and preventing the first protective cover 8, the dustproof net 11, and the second protective cover 9 from sliding.

[0034] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0035] When playing music using a Bluetooth speaker, the hand rotates the drive ring 18. The anti-slip groove 21 on the outer wall of the drive ring 18 increases the friction between the hand and the drive ring 18, preventing slippage. The drive ring 18 rotates along the annular groove 17 about the axis of the annular groove 17. In turn, the drive ring 18, which is slidably connected in the annular groove 17, drives the rack plate 19, which is fixed to the inner wall, to move along the clearance groove 15 on the inner wall of the receiving groove 12. Since the inner wall of the clearance groove 15 is rotatably connected to the limit block 16 through a spring shaft, and one end of the limit block 16 has a toothed groove 20, and since the rack plate 19 is meshed with the toothed groove 20, the rack plate 19... The movement of the limiting block 16 causes it to rotate around the axis of the spring shaft, disengaging from the Bluetooth speaker housing 1. Since the rack plate 19 is located within the clearance groove 15, it remains engaged with the toothed groove 20 at one end of the limiting block 16. Then, the driving ring 18 moves downwards. Because the driving ring 18 is located within the annular groove 17 on the outer wall of the first protective cover 8, its downward movement drives the first protective cover 8 to move downwards along the outer wall of the Bluetooth speaker housing 1. This downward movement of the first protective cover 8 causes the connecting rod 10, which is fixed to its lower end face, to move downwards. The downward movement of the connecting rod 10 also causes the second protective cover 9, fixed to its lower end face, to move downwards along the Bluetooth speaker housing. As the outer wall of the Bluetooth speaker housing 1 moves downward, the first protective cover 8, the connecting rod 10, and the second protective cover 9 also move downward, causing the dustproof net 11 fixed between the first protective cover 8 and the second protective cover 9 to move downward simultaneously. The downward movement of the first protective cover 8 also causes the guide block 14 fixed to the inner wall of the receiving groove 12 to move along the guide groove 13 opened on the outer wall of the Bluetooth speaker housing 1. When it moves to the point where the outer wall of the Bluetooth speaker housing 1 no longer presses against the outer wall of one end of the limiting block 16, one end of the limiting block 16 rotates out of the receiving groove 12 under the action of the spring restoring force of the spring shaft. Since the rack plate 19 is engaged with the toothed groove 20 at the other end of the limiting block 16, the limiting block 16... Rotation will drive the rack plate 19 to move back, which in turn drives the drive ring 18 to rotate. At this time, the lower end face of the lower cover 3 of the Bluetooth speaker shell 1 abuts against the upper end face of the limiting block 16. Several limiting blocks 16 support the Bluetooth speaker shell 1. Through the centrifugal fan 4 inside the Bluetooth speaker, the hot air inside the Bluetooth speaker is carried out, allowing the outside cold air to enter the guide hole 7 through the dustproof net 11 and then enter the Bluetooth speaker, forming a complete air flow channel. When there are water stains on the table, the Bluetooth speaker is also protected by the coordinated use of the first protective cover 8, the connecting rod 10, the second protective cover 9, and the limiting block 16.

[0036] When the Bluetooth speaker is not in use to play music, rotating the drive ring 18 moves the rack plate 19 fixed to the inner wall of the drive ring 18. The rack plate 19 drives the limiting block 16 to rotate into the clearance groove 15, and the drive ring 18 moves upward. The drive ring 18 drives the first protective cover 8, the connecting rod 10, the second protective cover 9 and the dustproof net 11 to move upward along the outer wall of the Bluetooth speaker shell 1. The upward movement of the second protective cover 9 will drive the sealing ring 5 fixed to the lower end face to move upward simultaneously. When the sealing ring 5 moves upward to be aligned with the lower end face of the lower cover 3 and the dustproof net 11 is aligned with the heat dissipation hole 6, the drive ring 18 is released. After the limiting block 16 is released from its restriction, one end of the limiting block 16 drives the rubber pad 22 to abut against the outer wall of the Bluetooth speaker shell 1 under the action of the spring restoring force of the spring shaft. The first protective cover 8 and the second protective cover 9 cannot move. The dustproof net 11 protects the heat dissipation hole 6, and the lower end face of the sealing ring 5 abuts against the table surface to prevent dust from entering from the guide hole 7 opened in the lower cover 3.

[0037] When a mobile phone or tablet needs to be charged, the drive ring 18 is rotated. The drive ring 18 drives the rack plate 19 to move, which in turn drives the limit block 16 to rotate and disengage from the Bluetooth speaker shell 1. Then, it moves slightly upward, causing the first protective cover 8, connecting rod 10, dustproof net 11, second protective cover 9 and sealing ring 5 to move upward a portion. (The Bluetooth speaker can be magnetically attracted to the end cover of the mobile phone or the rear cover of the tablet through the magnetic ring. Then, the magnetic coil emits magnetic energy outward. The mobile phone, tablet and other devices receive the magnetic energy through the charging magnetic receiving coil and convert it into current and voltage to charge the mobile phone or tablet battery.) The part in parentheses is the prior art of the cited patent publication number CN218183468U, which is not described in detail in this application.

[0038] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
