Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1 and 7, fig. 1 is a schematic structural diagram of an antistatic structure according to an embodiment of the present invention, and fig. 7 is a circuit diagram of an antistatic structure according to an embodiment of the present invention. The antistatic structure provided by an embodiment of the invention comprises a power supply component 10, a starting component 20 and a short circuit component 30. The initiating component 20 is used to ignite the fire suppression agent. The short circuit member 30 has a first connection portion 31 and a second connection portion 32, and the first connection portion 31 and the second connection portion 32 are electrically connected to both ends of the power supply member 10, and are electrically connected to both ends of the start member 20, respectively, so that the start member 20 and the short circuit member 30 are disposed in parallel.
According to the anti-static structure, when static electricity or strong electromagnetic field interference exists around the fire extinguishing device, external current can flow through the loop where the short connector 30 is located, but not through the loop where the starting component 20 is located due to the fact that the resistance of the short connector 30 is small, so that the effects of static electricity prevention and interference prevention can be achieved, and potential safety hazards caused by accidental starting of the fire extinguishing device under the situation are avoided. When the fire extinguishing apparatus needs to be started, the short connector 30 is pulled out, so that the resistance of the loop is increased, the resistance of the starting component 20 is relatively small, and thus, the high-voltage power generated by the power supply component 10 flows through the loop where the starting component 20 is located, and the fire extinguishing apparatus can be normally started to extinguish fire in a fire area.
In particular, in this embodiment, the actuating member 20 is an electrical initiator. Optionally, the electrical initiator is a resistive electrical initiator. When current passes through the electric initiator, the electric initiator initiates the fire extinguishing agent to burn; the fire extinguishing agent burns to produce fire extinguishing substances, and the fire extinguishing substances are sprayed out of the fire extinguishing device, so that fire can be extinguished in a fire area.
In one embodiment, referring to fig. 2 and 7, the antistatic structure further includes a conductive member 40, and the conductive member 40 further includes a first conductive member 41 electrically connected to the first connection portion 31 and a second conductive member 42 electrically connected to the second connection portion 32. One end of the first conductive member 41 is electrically connected to one end of the power supply member 10, and the other end is electrically connected to one end of the start member 20. One end of the second conductive member 42 is correspondingly and electrically connected to the other end of the power supply member 10, and the other end is electrically connected to the other end of the actuating member 20. It should be understood that the first connection portion 31 of the short circuit member 30 is electrically connected to one end of the power supply member 10 and one end of the starting member 20 through the first conductive member 41, and the second connection portion 32 of the short circuit member 30 is electrically connected to the other end of the power supply member 10 and the other end of the starting member 20 through the second conductive member 42, respectively, so as to form two parallel circuits. When there is static or strong electromagnetic field interference around the fire extinguishing device, because the resistance of the short-circuit piece 30 is smaller, external current will flow through the loop where the short-circuit piece 30 is located, but not through the loop where the starting component 20 is located, thus the effect of preventing static interference can be achieved, and the potential safety hazard caused by accidental starting of the fire extinguishing device under the condition is avoided. When the fire extinguishing apparatus needs to be started, the short connector 30 is pulled out from the loop, the loop is broken, the resistance between the first conductive member 41 and the second conductive member 42 is larger, the resistance of the starting member 20 is relatively smaller, and thus the high-voltage current generated by the power supply member 10 flows through the loop where the starting member 20 is located, and the fire extinguishing apparatus can be started normally to extinguish a fire area.
It should be noted that, since the first connection portion 31 and the second connection portion 32 of the short circuit member 30 have a certain distance, after the short circuit member 30 is pulled to separate the short circuit member 30 from the conductive member 40, a certain interval is formed between the first conductive member 41 and the second conductive member 42, and the interval is relatively large and stable, so that the resistance between the first conductive member 41 and the second conductive member 42 is large, thereby avoiding the short circuit starting member 20.
In this embodiment, the first conductive member 41 is a first conductive wire, and the second conductive member 42 is a second conductive wire.
In one embodiment, referring to fig. 2, 3 and 6, the antistatic structure further comprises a terminal 50. The terminal 50 includes a first terminal 51 and a second terminal 52, the first conductive member 41 is electrically connected to the first connection portion 31 of the short 30 through the first terminal 51, and the second conductive member 42 is electrically connected to the second connection portion 32 of the short 30 through the second terminal 52. The short 30 and the conductive member 40 are electrically connected by the terminal 50, and on the one hand, current can flow to the short 30 through the conductive member 40 and the terminal 50; on the other hand, the connection structure between the short circuit 30 and the conductive member 40 is simple, and the short circuit 30 and the conductive member 40 are easily separated in the process of pulling the short circuit 30. Of course, in other embodiments, the conductive member 40 and the terminal 50 may be an integral body with conductive function, such as conductive rubber.
In one embodiment, referring to fig. 4 and 7, the antistatic structure further includes a pull ring 60, and the shorting member 30 is connected to the pull ring 60. When the fire extinguishing device is needed to extinguish fire, the pull ring 60 is pulled, and the short connector 30 is separated from the first conductive piece 41 and the second conductive piece 42 when the pull ring 60 is pulled because the short connector 30 is connected to the pull ring 60. Because the short circuit member 30 is separated from the first conductive member 41 and the second conductive member 42, the resistance between the first conductive member 41 and the second conductive member 42 is relatively high, and the resistance of the starting member 20 is relatively low, so that the high voltage generated by the power supply member 10 flows through the circuit where the starting member 20 is located, and the fire extinguishing device is normally started to ignite the fire extinguishing agent for extinguishing fire. By providing tab 60 and attaching short 30 to tab 60, this facilitates pulling short 30. Of course, in other embodiments, a post may be provided, with the short 30 connected to one end of the post.
In one embodiment, referring to fig. 4 and 7, the antistatic structure further includes a safety pin 70, the safety pin 70 is disposed on the pull ring 60, and the short circuit member 30 is connected to the safety pin 70. When the fire extinguishing device is needed to extinguish fire, the pull ring 60 is pulled, and the short connector 30 is separated from the first conductive piece 41 and the second conductive piece 42 as the short connector 30 is connected to the pull ring 60 through the safety pin 70, and the short connector 30 can be driven to move while the pull ring 60 is pulled. Because the short circuit member 30 is separated from the first conductive member 41 and the second conductive member 42, the resistance between the first conductive member 41 and the second conductive member 42 is relatively high, and the resistance of the starting member 20 is relatively low, so that the high voltage generated by the power supply member 10 flows through the circuit where the starting member 20 is located, and the fire extinguishing device is normally started to ignite the fire extinguishing agent for extinguishing fire.
In one embodiment, referring to fig. 4, 5 and 7, the safety pin 70 is provided with a first limiting groove 72 adapted to the tab 60, and the tab 60 is provided in the first limiting groove 72. When the fire extinguishing device needs to be started, the pull ring 60 is pulled, and under the action of external force, the pull ring 60 drives the short connector 30 to separate from the first conductive piece 41 and the second conductive piece 42. Of course, in other embodiments, the safety pin 70 may also be provided with a first limiting hole, and the pull ring 60 is disposed through the first limiting hole.
In one embodiment, referring to fig. 5, 6 and 7, the safety pin 70 is provided with at least two second limiting grooves 73, wherein the two second limiting grooves 73 are located at both sides of the safety pin 70, respectively. One end of the short circuit element 30 is correspondingly provided with a first inserting part 33, the other end is correspondingly provided with a second inserting part 34, and the first inserting part 33 and the second inserting part 34 are arranged in the second limiting groove 73. Optionally, the first plugging portion 33 and the second plugging portion 34 are both connection hooks. When the fire extinguishing device needs to be started, as the first inserting portion 33 and the second inserting portion 34 of the short connector 30 are inserted into the second limiting groove 73 of the safety pin 70, the pull ring 60 is pulled, and the pull ring 60 can drive the short connector 30 to separate from the first conductive member 41 and the second conductive member 42 in the moving process. And, the short connector 30 is simple in connection structure with the safety pin 70, and convenient to assemble and disassemble.
In one embodiment, referring to fig. 8, the antistatic structure further includes a pressing member 80, where the pressing member 80 abuts against the power supply part 10. When the fire extinguishing device is required to be used, the pressing piece 80 is pressed, and the pressing piece 80 is abutted against the power supply part 10, so that the pressing piece 80 can drive the power supply part 10 to move in the moving process, and the power supply part 10 generates high-voltage electricity; the high voltage generated by the power supply unit 10 flows through the circuit in which the starting unit 20 is located, so that the fire extinguishing device can be normally started to ignite the fire extinguishing agent for extinguishing fire.
Further, referring to fig. 2, 5 and 8, the safety pin 70 is provided with a limiting portion 71 for limiting the movement of the pressing piece 80, the limiting portion 71 being located at one side of the pressing piece 80. The limiting portion 71 is provided in a direction in which the pressing member 80 drives the power supply member 10 to move. By providing the limiting portion 71, before the short connector 30 is not pulled out, the limiting portion 71 can limit the movement of the pressing member 80, so that the power supply member 10 cannot be driven to move even if the pressing member 80 bears a large pressure, thereby playing a role of safety and effectively preventing the pressing member 80 from being pressed down by mistake to start the fire extinguishing device.
In one embodiment, referring to fig. 2, 5 and 8, the safety pin 70 has a first hook 74. It should be noted that the first hook 74 is disposed toward the side wall of the container 90; when the short circuit member 30 is not pulled out, the first hook 74 abuts against the side wall of the container 90. Optionally, the first hook 74 is located on a groove wall of the first limiting groove 72 on a side away from the short circuit member 30. When the short circuit 30 is pulled to move, the first hook 74 is damaged under the action of the side wall of the container 90, so that whether the short circuit 30 is pulled out by a person can be judged through the first hook 74.
In one embodiment, referring to fig. 2, 5 and 8, the safety pin 70 has a tab 75. Since the safety pin 70 has the labeling portion 75, the manufacturer may set a label on the labeling portion 75, and a part of the label is located on the labeling portion 75 and another part of the label is located on the cover 92. After the user pulls on tab 60, the tab is broken, so that it can be determined whether or not short 30 has been pulled by a person.
In one embodiment, the power supply member 10 is a piezoelectric ceramic. The piezoelectric ceramic has piezoelectricity, and under the action of external force, positive and negative charges in the piezoelectric ceramic are relatively displaced to cause polarization, so that the piezoelectric ceramic generates bound charges, and the piezoelectric ceramic can absorb free charges from the outside. When a certain external pressure is applied to the piezoelectric ceramic, the piezoelectric ceramic can discharge, and then high-voltage current is generated. The high voltage current passes through the initiating component 20, and the initiating component 20 ignites the fire suppressant, which may then extinguish the fire.
Referring to fig. 8, a fire extinguishing apparatus includes a container 90 and an antistatic structure according to any of the above embodiments. The container 90 includes a housing 91, a cover 92, and an inner tube 93, the inner tube 93 is disposed in the housing 91, the cover 92 is disposed at an opening end of the housing 91, and the antistatic structure is disposed at the cover 92.
When static electricity or strong electromagnetic field interference exists around the fire extinguishing device, external current can flow through the loop where the short connector 30 is located, but not through the loop where the starting component 20 is located due to the small resistance of the short connector 30, so that the fire extinguishing device has the functions of static electricity prevention and interference prevention, and potential safety hazards caused by accidental starting of the fire extinguishing device under the condition are avoided. When the fire extinguishing apparatus needs to be started, the short connector 30 is pulled out, so that the resistance of the loop is increased, the resistance of the starting component 20 is relatively small, and thus, the high-voltage power generated by the power supply component 10 flows through the loop where the starting component 20 is located, and the fire extinguishing apparatus can be normally started to extinguish fire in a fire area.
The fire extinguishing agent is contained in the inner tube 93, and the activating member 20 is provided in the inner tube 93. Since the fire extinguishing agent releases a large amount of heat during the combustion process, the heat generated by the combustion of the fire extinguishing agent can be prevented from burning the user by disposing the inner tube 93 in the housing 91.
Further, the cover 92 includes a cover plate and a sidewall around the periphery of the cover plate, and the cover plate is provided with a mounting hole adapted to the safety pin 70. When the safety pin 70 is mounted, the safety pin 70 is inserted into the mounting hole, and a part of the safety pin 70 provided with the pull ring 60 is arranged outside the container 90, and a part of the safety pin 70 connected with the short connector 30 is arranged inside the container 90. Because the portion of the safety pin 70 provided with the pull ring 60 is located outside the container 90, pulling on the pull ring 60 brings the short link 30 out, facilitating activation of the fire suppression apparatus to extinguish the fire. Since the portion of the safety pin 70 to which the short link 30 is connected is provided outside the container 90, it is possible to prevent the short link 30 from being affected by rainwater, dust, or the like.
In one embodiment, referring to fig. 1, a second hooking jaw 921 is provided at a sidewall of the cover 92. Optionally, the second hooking claws 921 are provided with at least two, wherein the two second hooking claws 921 are oppositely disposed. Through setting up the second and collude the claw 921, the second colludes the claw 921 and can guarantee that pull ring 60 is fixed, prevents that pull ring 60 from appearing the phenomenon of rocking.
Specifically, in this embodiment, two second hooks 921 are provided, and the two second hooks 921 are disposed opposite to the side wall of the cover 92.
