[0002] Fire, as a common disaster, poses a serious threat to people's life and property safety. It is particularly important to understand how to prevent fire. The methods of fire prevention are to improve fire prevention awareness and reduce the occurrence of fire. Fire prevention must first start with improving fire prevention awareness. We must recognize the harmfulness of fire, understand the causes and patterns of fire, and thus remain vigilant in daily life. In public places and at home, we must abide by fire safety regulations, not randomly throw away cigarette butts, matches and other flammable items, not randomly pull and connect wires, and not privately pull and connect electrical equipment.

[0019] A method for using a security alarm device comprises the following steps:

[0020] S1. Acetone is injected into the first detection tube, the auxiliary detection tube and the fourth detection tube respectively, and the housing is fixed on the wall of the fire-prone area through the first fixing plate and the mounting hole. When the temperature rises abnormally, the acetone in the auxiliary detection tube inside the air inlet box will absorb heat, and the acetone will evaporate and vaporize, generating a large air pressure inside the auxiliary detection tube. The uneven heat absorption will cause a certain pressure difference inside the two auxiliary detection tubes, and the abnormal temperature signal in the air will be converted into a pressure signal;

[0021] S2. The vaporized acetone pushes the detection piston to slide inside the sensitive detection tube through the sensitive detection tube, and the detection piston slides to the other side. The sliding of the detection piston pushes the linkage frame to slide, driving the lifting rod to slide upward or downward. When the lifting rod does not slide, the middle tube is in an open state, and the connecting tube and the first hose are in a connected state through the upper connecting hole and the lower connecting hole. When sliding upward or downward, the middle tube will be closed, the connection between the connecting tube and the first hose will be closed, and the first hose and the connecting tube will be connected;

[0022] S3. When the lifting rod does not slide, the temperature is abnormal, and acetone absorbs heat and evaporates. The acetone inside the first detection tube pushes the auxiliary detection rod to slide, thereby driving the toggle piece on the auxiliary detection switch to rotate and generate an electrical signal. Similarly, the acetone inside the second hose pushes the left push rod, causing the left detection switch to generate an electrical signal. The electrical signals on the left detection switch and the auxiliary detection switch are transmitted to the control circuit board, so that the device sends a text message to the manager to inform the area with abnormal temperature, which needs to be checked to avoid fire.

[0023] S4. When the lifting rod slides upward or downward, and the middle tube is closed, the pressure pushes the right push rod and the left push rod respectively. When the outside temperature is slightly higher than sixty degrees, the acetone does not vaporize violently, and the left detection switch and the right detection switch generate a fluctuation signal. The threaded rod rotates, driving the first detection cylinder and the fourth detection cylinder to rotate outward, so that the first detection cylinder and the fourth detection cylinder extend out of the shell and are exposed to the air, which makes it easier to absorb heat in the air. When a fire occurs, the high temperature will cause the acetone to boil violently and generate a higher pressure, causing the left detection switch and the right detection switch to generate a strong fluctuation signal. The control circuit board and the SIM card dial the fire alarm to issue a fire warning.

[0024] As can be seen from the above, the security alarm device and the use method thereof provided by the present invention have the following technical effects.

[0025] First, when a fire occurs, the high temperature will cause the acetone inside the first detection tube and the second detection tube to boil violently, generating a high pressure, causing the right push rod and the left push rod to move back and forth, causing the left detection switch and the right detection switch to generate a strong fluctuation signal. At this time, the control circuit board and the SIM card will dial the fire alarm, issue a fire warning, and send a distress signal, reducing the waste of social public resources caused by notifying the fire for a simple accident, making effective use of public resources, and protecting the lives and property of residents.

[0026] Second: when the lifting rod does not slide, the acetone inside the first detection cylinder and the second detection cylinder will absorb heat and evaporate. The acetone inside the first detection cylinder enters the auxiliary gas cylinder through the first hose and the connecting pipe, pushing the auxiliary detection rod to slide and generating an electrical signal. Similarly, the acetone inside the second hose can enter the secondary detection tube through the second hose, causing the left detection switch to generate an electrical signal. The electrical signals on the left detection switch and the auxiliary detection switch are transmitted to the control circuit board, causing the device to send a text message to the manager, informing him of the area with abnormal temperature, which needs to be inspected to avoid fire.

[0039] Sensitive detection mechanisms are installed on both sides of the top edge of the housing 1, and the sensitive detection mechanisms are used to detect the temperature difference in the air;

[0040] A starting mechanism is installed on one side inner wall of the housing 1 near the top of the mounting plate 6, and the starting mechanism is used to convert the temperature difference in the air into a mechanical signal;

[0041] A valve mechanism is installed at an edge position near the top of one side of the mounting plate 6, and the valve mechanism is used to switch the flow direction of the gas;

[0045] In this embodiment, acetone is injected into the first detection cylinder 10 , the auxiliary detection cylinder 11 and the fourth detection cylinder 46 respectively, and the housing 1 is fixed to the wall of the fire prone area through the first fixing plate 5 and the mounting hole 4 .

[0047] In this embodiment, the auxiliary plug 13 serves to facilitate replacement of the acetone solution. When the external air temperature rises abnormally, the acetone in the auxiliary detection cylinder 11 inside the air inlet box 3 will absorb heat. When the temperature reaches 56 degrees on the middle plate, which exceeds the normal air temperature, the acetone will evaporate and vaporize, generating a relatively high air pressure inside the auxiliary detection cylinder 11. Since the two auxiliary detection cylinders 11 are located at a certain distance from each other, it will lead to uneven heat absorption, and a certain pressure difference will be generated inside the two auxiliary detection cylinders 11, converting the abnormal air temperature signal in the air into a pressure signal.

The sliding of the detection piston 16 pushes the linkage frame 17 to slide, thereby driving the linkage plate 19 to rotate.

Similarly, the acetone inside the second hose 44 can enter the secondary detection tube 45 through the second hose 44, pushing the left push rod 43, so that the left detection switch 41 generates an electrical signal, and the electrical signals on the left detection switch 41 and the auxiliary detection switch 48 are transmitted to the control circuit board 8, so that the device sends a text message to the manager to inform the area where the temperature abnormality occurs and the area needs to be inspected to avoid fire.

[0055] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the release mechanism includes a first rotating plate 57 rotatably connected to the inner wall of one side of the shell 1 near the bottom position, a second rotating plate rotatably connected to the inner wall of one side of the shell 1 near the bottom position, a first detection cylinder 10 is fixedly connected to the top of the first rotating plate 57, a fourth detection cylinder 46 is fixedly connected to the top of the second rotating plate, a replacement plug 58 is threadedly connected to the bottom of the first detection cylinder 10 and the fourth detection cylinder 46 respectively, a heat conducting frame is sleeved on the outer wall of the first detection cylinder 10 and the fourth detection cylinder 46 respectively, a motor 53 is fixedly connected to the bottom position of one side of the mounting plate 6, a threaded rod 54 is fixedly connected to one end of the output shaft of the motor 53, a lifting block 55 is threadedly connected to one end of the threaded rod 54, and a middle plate 56 is rotatably connected to both sides of the lifting block 55.

[0056] One end of the auxiliary tube 12 is connected to the sensitive detection tube 15, a part of the linkage frame 17 slides inside the first slide groove 18, the top end of the lifting rod 21 slides inside the second slide groove 24, the spring 23 is restricted inside the second fixed plate 22, the top of the lifting rod 21 is forked, and the two ends of the lifting rod 21 are fixedly connected to the first piston 28 and the third detection cylinder 36 respectively, and the upper connecting hole 30 is connected to the lower connecting hole 27.

[0057] The secondary detection tube 45 is connected to the middle tube 35 and the connecting tube 37 respectively, the right linkage rod 39 is slidably connected to the toggle piece on the right detection switch 40, the left linkage rod 42 is slidably connected to the toggle piece on the left detection switch 41, the auxiliary linkage rod 47 is slidably connected to the toggle piece on the auxiliary detection switch 48, the first hose 29 is connected to the first detection cylinder 10, the second hose 44 is connected to the fourth detection cylinder 46, the air plug 49 is connected to the outside, and the control circuit board 8 is electrically connected to the right detection switch 40, the left detection switch 41, the auxiliary detection switch 48 and the motor 53 respectively.

[0058] In this embodiment, when the lifting rod 21 slides upward or downward, similarly, uneven heating will produce a pressure difference, and the intermediate tube 35 is closed, the first hose 29 and the connecting tube 37 are connected, and the pressure inside the first detection cylinder 10 and the fourth detection cylinder 46 push the right push rod 38 and the left push rod 43 respectively. When the outside temperature is slightly higher than sixty degrees, the acetone does not vaporize violently, the right push rod 38 and the left push rod 43 squeeze the air inside the secondary detection tube 45 from each other, and the left detection switch 41 and the right detection switch 40 generate a fluctuation signal.

[0059] Further, the motor 53 is turned on to drive the threaded rod 54 to rotate, so that the lifting block 55 moves upward, thereby driving the middle plates 56 on both sides to rotate, so that the first rotating plate 57 and the second rotating plate respectively drive the first detection tube 10 and the fourth detection tube 46 to rotate outward, so that the first detection tube 10 and the fourth detection tube 46 extend out of the shell 1 and are exposed to the air, so that the heat conduction frame outside the first detection tube 10 and the fourth detection tube 46 can more easily absorb the heat in the air. When a fire occurs and the fire is fierce, the high temperature will cause the acetone inside the first detection tube 10 and the fourth detection tube 46 to boil violently, generate a higher pressure, and move the right push rod 38 and the left push rod 43 back and forth, so that the left detection switch 41 and the right detection switch 40 generate a strong fluctuation signal. At this time, the control circuit board 8 is matched with the SIM card 9 to dial the fire alarm phone, issue a fire warning, remind the manager, and issue a simple warning. By further confirming the occurrence of the fire and sending a distress signal, the situation of wasting social public resources caused by notifying the fire alarm due to a simple accident is reduced, so that public resources are effectively utilized and the safety of residents' lives and property is protected.

[0060] Working principle: When in use, acetone is injected into the first detection tube 10, the auxiliary detection tube 11 and the fourth detection tube 46 respectively, and the housing 1 is fixed on the wall of the fire-prone area through the first fixing plate 5 and the mounting hole 4. The auxiliary plug 13 is used to facilitate the replacement of the acetone solution. When the external air temperature rises abnormally, the acetone in the auxiliary detection tube 11 inside the air inlet box 3 will absorb heat. When the temperature reaches 56 degrees on the middle plate, exceeding the normal air temperature, the acetone will evaporate and vaporize, generating a large air pressure inside the auxiliary detection tube 11. Since the positions of the two auxiliary detection tubes 11 are at a certain distance, it will cause uneven heat absorption, which will cause a certain pressure difference inside the two auxiliary detection tubes 11, and convert the abnormal air temperature signal in the air into a pressure signal , the vaporized acetone pushes the detection piston 16 to slide inside the sensitive detection tube 15 through the sensitive detection tube 15. The pressure on one side is greater, and the detection piston 16 slides to the other side. The sliding of the detection piston 16 pushes the linkage frame 17 to slide, thereby driving the linkage plate 19 to rotate. The linkage plate 19 drives the lifting rod 21 to slide upward or downward, which plays a role in converting the pressure signal of abnormal temperature into a mechanical signal. The lifting rod 21 slides upward or downward, which drives the first piston 28 and the second piston 34 to slide upward or downward. When not sliding, the middle tube 35 is in an open state, and the connecting tube 26 and the first hose 29 are in a connected state through the upper connecting hole 30 and the lower connecting hole 27. When sliding upward or downward, the middle tube 35 will be When the lifting rod 21 is closed, the connection pipe 26 and the first hose 29 will be closed, and the first hose 29 and the connecting pipe 37 will be connected, which plays a role in converting the flow path of acetone gas. When the lifting rod 21 does not slide, if the first detection cylinder 10 and the fourth detection cylinder 46 detect that the temperature inside the housing 1 is abnormal, the acetone inside the first detection cylinder 10 and the fourth detection cylinder 46 will absorb heat and evaporate, and the acetone inside the first detection cylinder 10 enters the auxiliary gas cylinder 50 through the first hose 29 and the connecting pipe 26, pushing the auxiliary detection rod 52 to slide, thereby driving the toggle piece on the auxiliary detection switch 48 to rotate and generate an electrical signal. Similarly, the acetone inside the second hose 44 can enter the secondary detection tube 45 through the second hose 44, pushing the left push rod 43, so that the left detection switch 41 generates The electrical signal on the left detection switch 41 and the auxiliary detection switch 48 is transmitted to the control circuit board 8, so that the device sends a text message to the manager to inform the area where the temperature abnormality occurs. The area needs to be checked to avoid fire. When the lifting rod 21 slides up or down, similarly, uneven heating will produce a pressure difference, and the middle tube 35 is closed. The first hose 29 and the connecting tube 37 are connected. The pressure inside the first detection cylinder 10 and the fourth detection cylinder 46 push the right push rod 38 and the left push rod 43 respectively. When the outside temperature is slightly higher than 60 degrees, the acetone vaporization is not violent. The right push rod 38 and the left push rod 43 squeeze the air inside the secondary detection tube 45 from each other. The left detection switch 41 and the right detection switch 40 generate a fluctuation signal to start the motor 53.The threaded rod 54 is driven to rotate, so that the lifting block 55 moves upward, thereby driving the middle plates 56 on both sides to rotate, so that the first rotating plate 57 and the second rotating plate respectively drive the first detection tube 10 and the fourth detection tube 46 to rotate outward, so that the first detection tube 10 and the fourth detection tube 46 extend out of the housing 1 and are exposed to the air, so that the heat-conducting frame outside the first detection tube 10 and the fourth detection tube 46 can more easily absorb the heat in the air. When a fire occurs and the fire is fierce, the high temperature will cause the acetone inside the first detection tube 10 and the fourth detection tube 46 to boil violently, generating a high pressure, so that the right push rod 38 and the left push rod 43 move back and forth, so that the left detection switch 41 and the right detection switch 40 generate a strong fluctuation signal. At this time, the control circuit board 8 and the SIM card 9 dial the fire alarm phone, issue a fire warning, remind the manager, and issue a simple warning. By further confirming the occurrence of the fire and sending a distress signal, the situation of wasting social public resources caused by notifying the fire alarm for a simple accident is reduced, so that public resources are effectively utilized, and the safety of residents' lives and property is also protected.

4. The method for using a security alarm device according to claim 3, characterized in that: The following steps are involved: S1. Acetone is injected into the first detection tube (10), the auxiliary detection tube (11) and the fourth detection tube (46) respectively, and the housing (1) is fixed on the wall of the fire-prone area through the first fixing plate (5) and the mounting hole (4). When the temperature rises abnormally, the acetone in the auxiliary detection tube (11) inside the air inlet box (3) absorbs heat and evaporates, generating a large air pressure inside the auxiliary detection tube (11). The heat absorption is uneven, which will cause a certain pressure difference inside the two auxiliary detection tubes (11), and convert the abnormal temperature signal in the air into a pressure signal; S2, the vaporized acetone pushes the detection piston (16) to slide inside the sensitive detection tube (15) through the sensitive detection tube (15), and the detection piston (16) slides to the other side. The sliding of the detection piston (16) pushes the linkage frame (17) to slide, driving the lifting rod (21) to slide upward or downward. When the lifting rod (21) does not slide, the intermediate tube (35) is in an open state, and the connecting tube (26) and the first hose (29) are in a connected state through the upper connecting hole (30) and the lower connecting hole (27). When sliding upward or downward, the intermediate tube (35) will be closed, the connection between the connecting tube (26) and the first hose (29) will be closed, and the first hose (29) and the connecting tube (37) will be connected; S3, when the lifting rod (21) does not slide, the temperature is abnormal, acetone absorbs heat and evaporates, and the acetone inside the first detection tube (10) pushes the auxiliary detection rod (52) to slide, thereby driving the toggle piece on the auxiliary detection switch (48) to rotate and generate an electrical signal. Similarly, the acetone inside the second hose (44) pushes the left push rod (43), causing the left detection switch (41) to generate an electrical signal. The electrical signals on the left detection switch (41) and the auxiliary detection switch (48) are transmitted to the control circuit board (8), so that the device sends a text message to the manager to inform the area where the temperature is abnormal and that the area needs to be checked to avoid fire. S4, when the lifting rod (21) slides upward or downward, and the middle tube (35) is closed, the pressure pushes the right push rod (38) and the left push rod (43) respectively. When the outside temperature is slightly higher than 60 degrees, the acetone does not vaporize violently, the left detection switch (41) and the right detection switch (40) generate a fluctuation signal, the threaded rod (54) rotates, driving the first detection cylinder (10) and the fourth detection cylinder (46) to rotate outward, so that the first detection cylinder (10) and the fourth detection cylinder (46) extend out of the housing (1) and are exposed to the air, so that they are more likely to absorb heat in the air. When a fire occurs, the high temperature causes the acetone to boil violently, generating a higher pressure, so that the left detection switch (41) and the right detection switch (40) generate a strong fluctuation signal, and the control circuit board (8) and the SIM card (9) dial a fire alarm to issue a fire warning.
