Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth receivers, in particular to a Bluetooth receiver. Background Art

[0002] A Bluetooth receiver is a wireless audio device that receives and converts Bluetooth signals into analog audio signal output. The Bluetooth reception principle refers to the process of receiving and decoding wireless signals transmitted via Bluetooth into recognizable data. Specifically, a Bluetooth receiver uses an antenna to receive wireless signals sent by a Bluetooth device. The received signal is amplified and filtered, and then converted into a digital signal. Next, the Bluetooth receiver uses a demodulator to restore the original digital data and converts it into a recognizable audio signal through a decoder.

[0003] As a wireless audio device, Bluetooth receivers have a wide range of application scenarios and convenient usage. They are widely used in home entertainment, car audio, office and other fields. At the same time, Bluetooth receivers have the advantages of not requiring external devices, supporting mobile devices, and having a wide range of applications. With the continuous development of technology, the performance and stability of Bluetooth receivers are also constantly improving, bringing users a better user experience. There are many types of Bluetooth receivers, such as plug-in Bluetooth receivers.

[0004] At present, when using a plug-in Bluetooth receiver, it is usually necessary to insert the plug-in Bluetooth receiver into a corresponding device, and then pair the device such as a mobile phone with the Bluetooth receiver, so that the device can be controlled by the mobile phone and used.

[0005] However, in actual use, since the plug of the plug-in Bluetooth receiver needs to be frequently inserted into the connection device, and due to environmental influences, dust may enter the inside of the plug, thereby causing dust accumulation. In the long run, this may affect the connection quality of the plug-in Bluetooth receiver and reduce its service life. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a Bluetooth receiver to solve the technical problem that the plug of the plug-in Bluetooth receiver needs to be frequently inserted into the inside of the connecting device, and due to environmental influences, dust will enter the inside of the plug, thereby causing dust accumulation, which will affect the connection quality of the plug-in Bluetooth receiver in the long run and reduce its service life.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Bluetooth receiver, comprising a shell, a plug being slidably connected in the shell, and a group of card slots being arranged on the top of the plug, a movable plate being rotatably connected to one end of the shell, and a connecting plate being fixedly connected to one end of the shell close to the movable plate, cleaning bristles being arranged on both sides of the connecting plate and one side of the movable plate, a cavity being arranged on the top of the connecting plate, and a plurality of exhaust holes being arranged on the bottom of the cavity, an airbag being arranged at one end in the shell, and a one-way air inlet being arranged on one side of the airbag, an air pipe being arranged on the top of the shell, and one end of the air pipe being connected to the airbag, the other end of the air pipe being connected to the cavity, and a one-way air outlet being arranged on the end of the air pipe close to the cavity.

[0008] By adopting the above technical scheme, when the plug is used, the plug can be slid out of the shell, so that the squeezing force on the airbag disappears, and the airbag returns to its original state while inhaling air through the one-way air inlet. After the use of the plug is completed, the plug can be slid into the shell, so that one end of the plug squeezes the airbag, and the gas in the airbag can enter the cavity through the air pipe and the one-way outlet, and then be discharged through the exhaust port at the bottom of the cavity, so that the top of the plug can be cleaned by the gas. At the same time, when the plug slides into the shell, the outer surface of the plug will be cleaned by the cleaning bristles on both sides of the connecting plate and one side of the movable plate, so that dust can be avoided from accumulating inside the plug after long-term use of the plug, affecting the connection quality of the Bluetooth receiver, thereby improving the service life of the Bluetooth receiver.

[0009] The utility model is further configured that a slide groove is provided at the bottom of the shell, and a slider matching the slide groove is slidably connected in the slide groove, the slider is fixedly connected to the outer surface of the plug, and a plurality of protrusions are provided on the top of the slider.

[0010] By adopting the above technical solution, when the slider moves in the slide groove, the plug can be driven to slide in the shell synchronously, so the position of the plug can be changed to facilitate better use of the plug.

[0011] The utility model is further configured that one end of the shell is rotatably connected to a movable plate via a rotating shaft, and coil springs are arranged at the connection between the two ends of the rotating shaft and the shell.

[0012] By adopting the above technical solution, when the plug slides out of the shell, the bottom of the plug will squeeze the movable plate, causing the movable plate to rotate through the rotating shaft, so that the shell is in an open state, which is convenient for the plug to be inserted into other devices. At the same time, after the plug slides into the shell, the squeezing of the movable plate disappears, and the movable plate can be reset by the coil spring, so that the shell is closed, which can protect the plug inside the shell.

[0013] The utility model is further configured that a group of fixing grooves are arranged in the shell, and the outer surface of the plug is fixedly connected with elastic blocks which fit with the fixing grooves.

[0014] By adopting the above technical solution, when the plug is inserted into the shell, the elastic block will naturally enter the corresponding fixing groove, thereby fixing the position of the plug through the friction between the two. At the same time, when the plug slides in the shell, the elastic block is squeezed and will not affect the movement of the plug in the shell.

[0015] The utility model is further configured that limiting grooves are provided on both sides of the shell, and limiting blocks matching the limiting grooves are slidably connected in the limiting grooves, the limiting blocks are fixedly connected to both sides of the plug, and the limiting blocks are configured as a "T"-shaped structure.

[0016] By adopting the above technical solution, the precise position of the plug in the shell is ensured, and unnecessary movement of the plug in the shell can be prevented, thereby ensuring the stability and reliability of the equipment, while also avoiding accidental falling off of the plug, thereby improving the safety of the device.

[0017] The utility model is further configured that the outer surface of the airbag is configured in a spiral shape, and the airbag is made of elastic material.

[0018] By adopting the above technical solution, the outer surface of the airbag is spirally shaped and the airbag is made of elastic material, so that after the airbag is deformed by external force, it can return to its original shape after the external force is removed, so that it is easy to reuse.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model is provided with a sliding plug in the shell, so when the plug slides into the shell, one end of the plug squeezes the airbag, and the gas in the airbag can enter the cavity through the air pipe and the one-way outlet, and then the gas is discharged through the exhaust port at the bottom of the cavity, so that the top of the plug can be cleaned by the gas. At the same time, when the plug enters the shell, the outer surface of the plug can be cleaned by the cleaning bristles on both sides of the connecting plate and one side of the movable plate, so that dust can be prevented from accumulating inside the plug after long-term use of the plug, affecting the connection quality of the Bluetooth receiver, thereby improving the service life of the Bluetooth receiver.

DETAILED DESCRIPTION

[0025] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A Bluetooth receiver, such as Figure 1-3 As shown, it includes a shell 1, a plug 2 is slidably connected inside the shell 1, and a group of card slots 3 are arranged on the top of the plug 2, which can play a guiding role to facilitate better insertion into the connecting device.

[0028] Furthermore, a movable plate 5 is rotatably connected to one end of the shell 1 through a rotating shaft 4, and coil springs 6 are provided at the connection between the two ends of the rotating shaft 4 and the shell 1. When the plug 2 slides outward, the movable plate 5 can be squeezed, and the movable plate 5 can be rotated by the rotating shaft 4 to open the shell 1. When the plug 2 slides inward, the external force on the movable plate 5 disappears, and the coil spring 6 can be used to drive it to reset, so that the shell 1 is closed, thereby protecting the plug 2 inside it.

[0029] Then, a connecting plate 20 is fixedly connected to one end of the shell 1 near the movable plate 5, and cleaning bristles 7 are arranged on both sides of the connecting plate 20 and one side of the movable plate 5, so that when the plug 2 slides in the shell 1, the cleaning bristles 7 can be used for cleaning. A cavity 12 is arranged on the top of the connecting plate 20, and a plurality of exhaust holes 13 are arranged at the bottom of the cavity 12. An air bag 8 is arranged at one end of the shell 1, and a one-way air inlet 10 is arranged on one side of the air bag 8. An air pipe 9 is arranged on the top of the shell 1, and one end of the air pipe 9 is connected to the air bag 8, and the other end of the air pipe 9 is connected to the cavity 12, and a one-way air outlet 11 is arranged at one end of the air pipe 9 near the cavity 12. Therefore, when the air bag 8 is squeezed, the gas in the air bag 8 can be discharged through the air pipe 9 and the one-way air outlet 11, and after the external force on the air bag 8 disappears, it can restore its original state through its own characteristics while absorbing gas through the one-way air inlet 10 and storing it inside the air bag 8.

[0030] The outer surface of the airbag 8 is set to a spiral shape, and the airbag 8 is made of elastic material, so that the airbag 8 can be deformed under the action of external force and can return to its original shape after the external force is removed, so that it is easy to reuse.

[0031] Therefore, when in use, by providing a sliding plug 2 in the shell 1, when the plug 2 slides out of the shell 1, the squeezing force on the airbag 8 disappears, and the airbag 8 returns to its original state while sucking in air through the one-way air inlet 10, so that the gas is stored in the airbag 8. After the use of the plug 2 is completed, the plug 2 can be slid into the shell 1, so that one end of the plug 2 squeezes the airbag 8, and the gas in the airbag 8 can enter the cavity 12 through the air pipe 9 and the one-way air outlet 11, and then the gas is discharged through the exhaust hole 13 at the bottom of the cavity 12, so that the top of the plug 2 can be cleaned by the gas. At the same time, when the plug 2 slides into the shell 1, the outer surface of the plug 2 will be cleaned by the cleaning bristles 7 on both sides of the connecting plate 20 and one side of the movable plate 5, so that dust can be avoided from accumulating inside the plug 2 after long-term use of the plug 2, affecting the connection quality of the Bluetooth receiver, thereby improving the service life of the Bluetooth receiver.

[0032] A slide groove 18 is further provided at the bottom of the shell 1, and a slider 19 matching the slide groove 18 is slidably connected in the slide groove 18, and a damping structure is provided at the connection between the slider 19 and the slide groove 18. The slider 19 is fixedly connected to the outer surface of the plug 2. Therefore, when the slider 19 slides in the slide groove 18, the plug 2 can slide in the shell 1, thereby changing the position of the plug 2. A plurality of protrusions are provided on the top of the slider 19, which can increase the friction between the slider 19 and the contact surface, so as to better drive the slider 19 to move. At the same time, a group of fixed grooves 15 are provided in the shell 1, and an elastic block 14 matching the fixed groove 15 is fixedly connected to the outer surface of the plug 2. Therefore, when the plug 2 slides in the shell 1, the elastic block 14 is squeezed and deformed, but it does not affect the sliding of the plug 2 in the shell 1. When the elastic block 14 slides into the corresponding fixed groove 15, the extrusion force on the elastic block 14 disappears and returns to its original state, thereby increasing the friction between the two, thereby fixing the position of the plug 2.

[0033] At the same time, limiting grooves 17 are arranged on both sides of the shell 1, and limiting blocks 16 matching the limiting grooves 17 are slidably connected in the limiting grooves 17, and a damping structure is arranged at the connection between the limiting grooves 17 and the limiting blocks 16. The limiting blocks 16 are fixedly connected to both sides of the plug 2, and the limiting blocks 16 are arranged in a "T"-shaped structure, which can ensure the precise position of the plug 2 in the shell 1 and prevent the plug 2 from moving unnecessarily in the shell 1, thereby ensuring its stability and reliability, and preventing the plug 2 from accidentally falling off, thereby improving the safety of the device.

[0034] In this embodiment, the one-way air inlet 10 and the one-way air outlet 11 are existing structures, which realize one-way flow of gas through the internal structure to prevent reverse inflow, thereby ensuring its normal operation and safety. The one-way air inlet 10 inhales gas by restoring the airbag 8 to its original state; the one-way air outlet 11 discharges gas by squeezing gas, which is a structure known to technicians in this field.
