Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch with a dustproof structure. Background Art

[0002] A switch is a device that completes the information exchange function in a communication system. In a computer network system, the concept of switching is an improvement on the shared working mode. A HUB is a shared device. The HUB itself cannot identify the destination address. When host A in the same LAN transmits data to host B, the data packet is transmitted in a broadcast mode on the network with the HUB as the architecture. Each terminal determines whether to receive it by verifying the address information in the data packet header. In this working mode, only one group of data frames can be transmitted on the network at the same time. If a collision occurs, it must be retried. This method is to share network bandwidth.

[0003] In the prior art, for example, announcement number CN219536210U proposes a switch with a dustproof structure. This technical solution discloses a switch with a dustproof structure, which relates to the field of switches and includes a housing, a mounting plate, a connecting plate and a mainboard. The mounting plate is slidably arranged in the housing, the mainboard is fixedly arranged on the upper surface of the mounting plate, the connecting plate is fixedly arranged on the front side of the mounting plate and is located on the front side of the housing, a clamping mechanism is arranged between the housing and the connecting plate and they are clamped to each other through the clamping mechanism, a heat dissipation port is provided on the upper side of the housing, and a dustproof net is fixedly arranged in the heat dissipation port. The utility model does not require the removal of screws, improves maintenance efficiency, avoids the loss of screws, and is convenient for people to use;

[0004] However, the existing switches are not easy to dissipate heat efficiently during use. The slow heat dissipation rate easily leads to a high temperature of the switch, and even burns the motherboard inside the switch, causing the switch to be unable to be used normally, thereby affecting the service life of the switch.

[0005] In order to solve the above problems, the present application proposes a switch with a dustproof structure. Utility Model Content

[0006] The utility model aims to provide a switch with a dustproof structure, which is mainly used to solve the problem that the existing switch has a slow heat dissipation rate, which easily leads to a high temperature of the switch and reduces the service life of the switch.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the switch is in use, the switch is connected to the power supply, and the fan inside the shell is rotated through the operation of the driving component inside the cavity.

[0011] 2. Beneficial effect: The fan arranged at the bottom of the inner wall of the shell can rotate when the driving component inside the cavity is operated.

[0013] Preferably, both sides of the frame at the top of the shell are fixedly connected with L-shaped fixing blocks, screws pass through the L-shaped fixing blocks, and threaded holes matching the screws are opened on the frame. After the switch is used for a long time, a lot of dust may adhere to the dust net, thereby affecting the heat dissipation efficiency of the switch. Therefore, after people remove the screws on the L-shaped fixing blocks, they can remove the frame and the dust net from the shell, so that people can clean the dust on the dust net conveniently. After cleaning, insert the frame between the two L-shaped fixing blocks, and install the screws on the L-shaped fixing blocks. Tighten the screws to make them threadedly connected to the frame, so as to better fix the frame and the switch can be used normally.

[0014] Preferably, a plurality of ventilation holes are provided at the bottom of the shell, and the inner walls of the ventilation holes are fixedly connected with filter nets. During the use of the switch, the drive component will emit a certain amount of heat, so the multiple ventilation holes provided at the bottom of the shell can play a better heat dissipation effect on the drive component.

[0024] 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.

[0025] See also Figure 1-5A switch with a dustproof structure includes a housing 1, a symmetrical fan 2 is rotatably connected to the bottom of the inner wall of the housing 1, a cavity 3 is opened at the bottom of the housing 1, a driving component is fixedly connected to the bottom of the inner wall of the cavity 3, and the driving component is fixedly connected to the fan 2. When the switch is used, the switch is connected to a power supply, and the fan 2 inside the housing 1 can be rotated through the operation of the driving component inside the cavity 3. A plurality of ventilation holes 15 are opened at the bottom of the housing 1. During the use of the switch, the driving component will emit a certain amount of heat, so the plurality of ventilation holes 15 opened at the bottom of the housing 1 can play a better heat dissipation role for the driving component. The inner wall of the ventilation hole 15 is fixedly connected with a filter screen, which can effectively prevent dust from entering the cavity 3 through the ventilation hole 15, thereby effectively ensuring the normal use of the switch. The top of the housing 1 is provided with a through slot 4, so that the fan 2 can rotate while the gas inside the housing 1 flows, thereby achieving a better heat dissipation effect on the motherboard inside the switch. The top of the housing 1 is connected with a frame 5 above the through slot 4, and the inner wall of the frame 5 is fixedly connected with a dustproof net 6, which can effectively prevent dust from entering the housing 1 through the through slot 4 and affecting the normal operation of the switch. The top of the housing 1 is fixed on both sides of the frame 5. The switch is fixedly connected with an L-shaped fixing block 12, and symmetrical screws 13 are passed through the L-shaped fixing block 12. The frame 5 is provided with threaded holes 14 that match the screws 13. After the switch is used for a long time, a lot of dust may adhere to the dust screen 6, thereby affecting the heat dissipation efficiency of the switch. Therefore, after people remove the screws 13 on the L-shaped fixing block 12, the frame 5 and the dust screen 6 can be removed from the housing 1, so that people can clean the dust on the dust screen 6 conveniently. After cleaning, the frame 5 is inserted between the two L-shaped fixing blocks 12, and multiple screws 13 are installed to the L-shaped fixing blocks 12. By tightening the screw 13 to make it threadedly connected with the frame 5, the frame 5 can be better fixed, and the switch can be used normally. The screw 13 is an embedded hexagonal setting, which allows the screw 13 to rotate better during installation and reduces the possibility of slip angle. The upper end surface of the screw 13 is not higher than the top of the L-shaped fixing block 12, so that the screw 13 will not protrude and wear, thereby effectively extending the service life of the screw 13. The four corners of the bottom of the shell 1 are fixedly connected with support feet 16, which can increase the contact area between the shell 1 and the air, so that the heat dissipation effect is better during the use of the switch.

[0026] like Figure 3As shown, the driving assembly includes a motor 7 fixedly installed at the bottom of the inner wall of the cavity 3, a driving wheel 8 is fixedly connected to the output end of the motor 7, and a rotating shaft 9 is fixedly connected to the axis center of the bottom of the two fans 2. The rotating shaft 9 extends to the inside of the cavity 3 and is rotatably connected with the shell 1. One end of the rotating shaft 9 extending to the inside of the cavity 3 is fixedly connected to the driving wheel 8, and the other end of the rotating shaft 9 extending to the inside of the cavity 3 is fixedly connected to the driven wheel 10. The driving wheel 8 and the driven wheel 10 are sleeved with a belt 11. The motor 7 is electrically connected to the controller, and the controller can send an electrical signal to the motor 7 to control the motor 7 to start. When the switch is used, the switch is connected to the power supply, and the motor 7 is controlled by the controller to start. The operation of the motor 7 can rotate the driving wheel 8, and the rotation of the driving wheel 8 can make the driven wheel 10 rotate synchronously through the belt 11. When the driving wheel 8 and the driven wheel 10 rotate synchronously, the rotating shaft 9 can drive the two fans 2 at the bottom of the inner wall of the shell 1 to rotate synchronously, thereby having a good heat dissipation effect on the mainboard inside the shell 1, thereby effectively ensuring the normal use of the switch.

[0027] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0028] When the switch is used, the switch is connected to a power source, and the controller controls the motor 7 to start. The operation of the motor 7 can rotate the driving wheel 8, and the driving wheel 8 can rotate through the belt 11 to synchronously rotate the driven wheel 10. When the driving wheel 8 and the driven wheel 10 rotate synchronously, the rotating shaft 9 can drive the two fans 2 at the bottom of the inner wall of the shell 1 to rotate synchronously. Through the through slot 4 opened at the top of the shell 1, the air inside the shell 1 can flow while the fan 2 rotates, thereby achieving a better heat dissipation effect on the mainboard inside the switch. The frame 5 set at the top of the shell 1 and the dustproof net 6 set inside the frame 5 can effectively prevent dust from entering the shell 1. , thereby effectively ensuring the normal use of the switch. After the switch is used for a long time, a lot of dust may adhere to the dustproof net 6, thereby affecting the heat dissipation efficiency of the switch. Therefore, after people remove the multiple screws 13 on the L-shaped fixing block 12, the frame 5 and the dustproof net 6 can be removed from the shell 1, so that it is convenient for people to clean the dust on the dustproof net 6. After cleaning, the frame 5 is inserted between the two L-shaped fixing blocks 12, and the multiple screws 13 are installed on the L-shaped fixing blocks 12. Tighten the screws 13 to make them threadedly connected with the frame 5, so that the frame 5 can be better fixed, and the switch can be used normally.
