Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The embodiment of the present invention provides a repeater for a computer local area network to solve the problem that the existing smoke fire alarm is generally installed at a high place, such as the top of a room, and the air flow speed at the top of the room is slow. When a fire occurs, the smoke fire alarm cannot sense the smoke in time and the reaction time is long, resulting in the fire being out of control after the alarm sounds. At the same time, the repeater is generally placed on the ground, on a table, or directly plugged into a socket when in use, so that during the process of transmitting the signal, the signal of the repeater will be blocked by many obstacles on the ground, resulting in poor quality of the signal transmitted by the repeater.

[0032] The technical solution in the embodiment of the present invention is to solve the above technical problems. The overall idea is as follows: the repeater body 13 and the fire alarm body 14 are symmetrically distributed inside the fixed component and installed on the top of the roof, which changes the installation position of the traditional repeater and improves the signal transmission quality of the repeater body 13. At the same time, an air guide component is arranged in the fixed component so that the air guide component continuously introduces airflow from the outside to the fixed component, thereby achieving heat dissipation of the repeater body 13 and increasing the gas volume detected by the fire alarm body 14 per unit time.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] The present invention provides a repeater for a computer local area network, comprising:

[0036] Fixed component: The fixed component has a repeater body 13 and a fire alarm body 14 inside, and the fixed component is used to fix the repeater body 13 and the fire alarm body 14.

[0037] An air guide component; the air guide component is located inside the fixed component, and the air guide component is used to introduce air flow into the fixed component.

[0038] The repeater body 13 and the fire alarm body 14 are both semi-annular in shape, and the repeater body 13 and the fire alarm body 14 are fixedly and symmetrically installed inside the fixed component.

[0039] Smoke fire alarms are usually installed at higher places, such as indoor roofs;

[0040] However, when using a repeater, it is usually placed on the ground, on a table, or directly plugged into a socket;

[0041] The fire alarm body 14 and the repeater body 13 are designed to be semi-circular and fixedly symmetrically installed inside the housing 11, so that the positions of the repeater body 13 and the fire alarm body 14 are fixed by a fixing assembly so that they form a whole, which is convenient for installing the repeater body 13 and the fire alarm body 14 together on the top of the house through the fixing assembly, and taking advantage of the space advantage of the smoke sensor being installed at a higher position in real life, the ground space occupation is reduced while also avoiding the influence of ground obstacles on the repeater signal transmission, thereby improving the transmission quality of the signal transmitted by the repeater body 13, and at the same time, the semi-circular design of the fire alarm body 14 and the repeater body 13 can make the structure of the fixing assembly compact and will not occupy too much installation space;

[0042] The air guide assembly is installed inside the fixed assembly, and can continuously introduce airflow from the outside of the fixed assembly to the inside of the fixed assembly, thereby accelerating the airflow speed inside the fixed assembly, facilitating heat dissipation of the repeater body 13 installed in the fixed assembly. At the same time, the continuously introduced airflow also increases the gas volume detected by the fire alarm body 14 per unit time, so that the fire alarm can detect smoke in the air earlier, thereby improving the ability of the smoke fire alarm to monitor fire in a timely manner;

[0043] Compared with the existing smoke fire alarm, which is generally installed at a higher place, such as the top of the room, the air flow speed at the top of the room is slow. When a fire occurs, the smoke fire alarm cannot sense the smoke in time, and the reaction time is long, resulting in the fire being out of control after the alarm sounds. At the same time, the repeater is generally placed on the ground, on a table, or directly plugged into a socket when in use, so that during the process of transmitting the signal, the signal will be blocked by many obstacles on the ground, resulting in poor quality of the signal transmitted by the repeater;

[0044] The present invention installs the fire alarm body 14 and the repeater body 13 inside the fixing component, changes the installation position of the repeater body 13, improves the signal transmission quality of the repeater, and utilizes the air guide component to introduce airflow to achieve the heat dissipation of the repeater body 13 and the fire monitoring ability of the fire alarm body 14.

[0045] As a specific embodiment of the present invention, the fixing assembly includes: a shell 11 and an end cover 12, wherein the shell 11 is stepped and the upper surface of the upper end of the shell 11 is fixedly connected to the lower surface of the end cover 12;

[0046] The fixing assembly includes a shell 11 and an end cover 12. The shell 11 is stepped and the upper surface of the upper end of the shell 11 is fixedly connected to the lower surface of the end cover 12. The stepped shape of the shell 11 reduces the space occupied by the shell 11. The lower surface of the end cover 12 is fixedly connected to the upper surface of the upper end of the shell 11, so that the shell 11 and the end cover 12 can be fixedly installed on the top of the roof, and the shell 11 can be closed to achieve a dust-proof effect.

[0047] As a specific embodiment of the present invention, the air guide assembly includes an air guide fan 21, an air guide chamber 22, and a first air guide pipe 23 and a second air guide pipe 24 connected to the air guide chamber 22; the air guide fan 21 is located at the lower end of the air guide chamber 22;

[0048] The air guide chamber 22 is placed inside the upper end of the housing 11, and an air guide fan 21 is provided at the lower end of the air guide chamber 22. A first air guide pipe 23 is provided at the front end of the air guide chamber 22, and a second air guide pipe 24 is provided at the rear end.

[0049] When the air guide fan 21 rotates, the air is sucked in from the outside and blown into the air guide chamber 22 from the lower end. The air is gathered in the air guide chamber 22 and input to the top of the housing 11 through the No. 1 air guide pipe 23 connected at the front end of the air guide chamber 22 and the No. 2 air guide pipe 24 installed at the rear end, taking away the heat in the air around the repeater body 13, thereby achieving the heat dissipation effect on the repeater body 13.

[0050] At the same time, the continuously introduced airflow will be detected by the fire alarm body 14, which increases the gas volume detected by the fire alarm body 14 per unit time, thereby improving the fire monitoring capability of the fire alarm body 14.

[0051] As a specific embodiment of the present invention, a heat dissipation port 111 is provided on the outer surface of the upper end of the housing 11, and the heat dissipation port 111 opens tilted downward;

[0052] The outer surface of the upper end of the shell 11 is provided with a heat dissipation port 111, and the opening of the heat dissipation port 111 is inclined downward. When the gas gathered in the air guide chamber 22 is transmitted through the No. 1 air guide pipe 23 and the No. 2 air guide pipe 24, and reaches the upper end of the shell 11 to dissipate heat for the repeater body 13, the gas with heat is discharged from the heat dissipation port 111 at the upper end of the shell 11, thereby achieving the heat dissipation effect of the repeater body 13;

[0053] In addition, the heat dissipation port 111 opens tilted downward to prevent dust in the air from being deposited into the interior of the housing 11 when the housing 11 is statically installed, thereby achieving a dustproof effect for the housing 11 .

[0054] As a specific implementation of the present invention, an antenna 112 and a buzzer 113 are provided at the bottom of the outer surface of the upper end of the shell 11 .

[0055] An antenna 112 is provided at the bottom of the upper outer surface of the housing 11 and at a position corresponding to the repeater body 13. A buzzer 113 is provided at the bottom of the upper outer surface of the housing 11 and at a position corresponding to the smoke fire alarm 14. When the repeater body 13 is connected to the network and powered on, the antenna 112 realizes the functions of copying, adjusting and amplifying the signal.

[0056] When the fire alarm body 14 is powered on and working, it will send out an alarm to the outside world through the buzzer 113 when it detects that the smoke concentration in the air is too high.

[0057] As a specific embodiment of the present invention, the diameter of the lower end of the shell 11 is smaller than the diameter of the upper end of the shell 11, an air guide chamber 22 is provided inside the upper end of the shell 11, and an air guide fan 21 is provided inside the lower end of the shell 11;

The diameter of the lower end of the shell 11 is smaller than the diameter of the upper end of the shell 11, so that the air guide chamber 22 of the shell 11 and the air guide fan 21 can be installed while reducing the occupied space, making the structure more compact and improving the flow rate of the gas inside the shell 11.

[0059] As a specific embodiment of the present invention,

[0060] One end of the No. 1 air pipe 23 is connected to the relay body 13;

[0061] One end of the second air guide pipe 24 is connected to the fire alarm body 14;

[0062] The gas in the air guide chamber 22 enters the interior of the repeater body 13 connected to the first air guide pipe 23 through the first air guide pipe 23, and the air flow inside the repeater body 13 takes away the heat, thereby improving the heat dissipation capacity of the repeater body 13;

[0063] At the same time, the gas in the air guide chamber 22 enters the interior of the fire alarm body 14 connected to the No. 2 air guide pipe 24 through the No. 2 air guide pipe 24, which facilitates the smoke sensing of the fire alarm body 14, increases the gas volume detected by the fire alarm body 14 per unit time, and thereby improves the fire monitoring capability of the fire alarm body 14.

[0064] As a specific embodiment of the present invention, the lower end of the housing 11 is threadedly connected to the soundproof cover 3;

[0065] The lower end of the shell 11 is threadedly connected to the sound insulation cover 3. When the air guide fan 21 is powered on, it will generate slight noise. The sound insulation of the sound insulation cover 3 can reduce the noise transmitted to the outside when the air guide fan 21 is working, reducing the interference with the normal life or work of the personnel; the sound insulation cover 3 threadedly connected to the lower end of the shell 11 can facilitate the installation or disassembly of the sound insulation cover 3, which is convenient for later maintenance.

[0066] As a specific embodiment of the present invention, an air guide hole 31 is opened at the upper end of the soundproof cover 3;

[0067] When the air guide fan 21 is powered on and working, it needs to suck the external gas into the air guide chamber 22, and the upper end of the sound insulation cover 3 is provided with an air guide hole 31 to facilitate the air guide fan 21 to suck the external gas into the air guide chamber 22 from the air guide hole 31 when the air guide fan 21 is powered on and working, ensuring that the air guide fan 21 has sufficient airflow to inhale.

[0068] As a specific embodiment of the present invention, the soundproof cover 3 is spherical and has a honeycomb sound-absorbing cotton 32 bonded to its inner surface;

[0069] The soundproof cover 3 is spherical and has a honeycomb sound-absorbing cotton 32 bonded to its inner surface, forming a closed soundproof space at the lower end of the shell 11. At the same time, the good noise absorption ability of the honeycomb sound-absorbing cotton 32 is utilized to further improve the soundproof effect of the soundproof cover 3.

[0070] Working principle: by designing the fire alarm body 14 and the repeater body 13 into a semi-ring shape, and fixing and symmetrically installing them inside the housing 11, the repeater body 13 and the fire alarm body 14 are fixed by a fixing assembly to form a whole, so that the repeater body 13 and the fire alarm body 14 can be installed together on the top of the house by the fixing assembly, and the space advantage of the smoke sensor being installed at a higher position in real life is utilized to reduce the ground space occupation while avoiding the influence of ground obstacles on the repeater signal transmission, thereby improving the transmission quality of the signal transmitted by the repeater body 13. At the same time, the semi-ring design of the fire alarm body 14 and the repeater body 13 can make the structure of the fixing assembly compact and will not occupy too much installation space;

[0071] The air guide component is installed inside the fixed component, and can continuously introduce airflow from the outside of the fixed component to the inside of the fixed component, thereby accelerating the airflow speed in the fixed component and facilitating the heat dissipation of the repeater body 13 installed in the fixed component. At the same time, the continuously introduced airflow also increases the gas volume detected by the fire alarm body 14 per unit time, so that the fire alarm can monitor smoke in the air earlier, thereby improving the ability of the smoke fire alarm to monitor fire in a timely manner.
