Technical Field

[0001] This utility model relates to the technical field of fire extinguishers, and in particular to a fire extinguisher with a monitoring module. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are common fire-fighting equipment, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components and are designed for different types of fires. They can be categorized as foam, dry powder, acid / alkali, or other types.

[0003] Most existing fire extinguishers are placed in fire cabinets in public spaces. However, these cabinets do not have a structure to monitor for leaks. Although fire extinguishers need to be inspected regularly by the fire department, if a leak occurs before inspection, the extinguisher cannot be used properly when needed, which could lead to an expansion of the disaster area, further increase losses, and compromise safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fire extinguisher with a monitoring module to solve the problem mentioned in the background art that the existing fire cabinets do not have a fire extinguisher leakage monitoring structure, and once a leak occurs, the fire extinguisher will not be able to be used normally when needed, resulting in poor safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguisher with a monitoring module, comprising a fire box, a battery module fixedly connected to the left side of the fire box, two mounting plates fixedly connected to both the left and right sides of the fire box, positioning bolts threadedly connected to the front of the four mounting plates, a support plate fixedly connected to the inner rear wall of the fire box, two fire extinguisher bodies overlapping the upper surface of the support plate, two straps snapped onto the inner rear wall of the fire box at positions corresponding to the two fire extinguisher bodies, a sealing frame inserted into the front of the fire box, a glass cover fixedly connected to the front of the sealing frame, and monitoring components fixedly connected to the upper surface of the fire box and the front of the sealing frame;

[0006] The monitoring component includes an airtight structure and a monitoring structure. The airtight structure is used to seal the inside of the fire extinguisher box, and the monitoring structure is used to monitor for air leakage in the fire extinguisher body in real time.

[0007] Preferably, the airtight structure includes a strip frame, the front of which is fixedly connected to the sealing frame, an air storage cylinder is fixedly connected to the inner wall of the strip frame, a piston is slidably connected to the inner wall of the air storage cylinder, a push rod is fixedly connected to the left side of the piston, a connecting pipe is connected to the surface of the air storage cylinder, and sealing airbags are fixedly connected to the upper and lower surfaces and the left and right sides of the sealing frame.

[0008] Preferably, the left side of both the air storage cylinder and the strip frame is provided with a circular hole that matches the push rod, the end of the connecting pipe away from the air storage cylinder passes through the sealing frame and communicates with the inside of the sealing airbag, and the back of the strip frame is provided with a through hole that matches the connecting pipe.

[0009] Preferably, the monitoring structure includes a positioning frame, which is fixedly connected to the upper surface of the fire box. An audible and visual alarm is fixedly connected to the upper surface of the positioning frame, and a circular hole is opened on the lower surface of the positioning frame. A monitoring cylinder is fixedly connected to the inner wall of the circular hole.

[0010] Preferably, the upper and lower surfaces of the monitoring cylinder are provided with positioning holes, and a monitoring rod is slidably connected to the inner wall of the two positioning holes. The bottom end of the monitoring rod extends into the interior of the fire box and is fixedly connected to a push plate, and the top end of the monitoring rod extends into the interior of the positioning frame and is fixedly connected to a contact plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a fire extinguisher with a monitoring module, including a fire box 1, a battery module 2 fixedly connected to the left side of the fire box 1, two mounting plates 3 fixedly connected to both the left and right sides of the fire box 1, positioning bolts 4 threadedly connected to the front of the four mounting plates 3, a support plate 5 fixedly connected to the inner rear wall of the fire box 1, two fire extinguisher bodies 6 overlapping the upper surface of the support plate 5, two straps 7 snapped onto the inner rear wall of the fire box 1 at positions corresponding to the two fire extinguisher bodies 6, a sealing frame 8 inserted into the front of the fire box 1, a glass cover 9 fixedly connected to the front of the sealing frame 8, and a monitoring component 10 fixedly connected to the upper surface of the fire box 1 and the front of the sealing frame 8.

[0021] The monitoring component 10 includes an airtight structure 11 and a monitoring structure 12. The airtight structure 11 is used to seal the inside of the fire box 1, and the monitoring structure 12 is used to monitor the air leakage of the fire extinguisher body 6 in real time.

[0022] Furthermore, the airtight structure 11 includes a strip frame 1101, which is fixedly connected to the front of the sealing frame 8. An air reservoir 1102 is fixedly connected to the inner wall of the strip frame 1101, and a piston 1103 is slidably connected to the inner wall of the air reservoir 1102. A push rod 1104 is fixedly connected to the left side of the piston 1103. A connecting pipe 1105 communicates with the surface of the air reservoir 1102. Sealing airbags 1106 are fixedly connected to the upper and lower surfaces and the left and right sides of the sealing frame 8. Both the air reservoir 1102 and the left side of the strip frame 1101 have circular holes adapted to the push rod 1104. The end of the connecting pipe 1105 away from the air reservoir 1102 passes through the sealing frame 8 and connects to the sealing airbag 1106. The internal components are interconnected. The back of the strip frame 1101 has a through hole that matches the connecting pipe 1105. After the fire extinguisher body 6 is placed into the fire box 1, it is secured and positioned using the straps 7. At the same time, the sealing frame 8 is secured to the front of the fire box 1. Then, push the push rod 1104 to the right, causing the push rod 1104 to drive the piston 1103 to move to the right inside the gas cylinder 1102. The piston 1103 can compress the gas inside the gas cylinder 1102, allowing it to enter the sealing airbag 1106 through the connecting pipe 1105. This causes the sealing airbag 1106 to expand in the contact gap between the sealing frame 8 and the inner wall of the fire box 1, enhancing the sealing effect of the fire box 1 and thus improving the monitoring accuracy.

[0023] Furthermore, the monitoring structure 12 includes a positioning frame 1201, which is fixedly connected to the upper surface of the fire box 1. An audible and visual alarm 1202 is fixedly connected to the upper surface of the positioning frame 1201. A circular hole is formed on the lower surface of the positioning frame 1201, and a monitoring cylinder 1203 is fixedly connected to the inner wall of the circular hole. Positioning holes are formed on both the upper and lower surfaces of the monitoring cylinder 1203. A monitoring rod 1204 is slidably connected to the inner wall of the two positioning holes. The bottom end of the monitoring rod 1204 extends into the interior of the fire box 1 and is fixedly connected to a push plate 1205. The top end of the monitoring rod 1204 extends into the interior of the positioning frame 1201 and is fixedly connected to a contact plate 1206. A contact switch 1207 is fixedly connected to the inner top wall of the positioning frame 1201. Furthermore, the position of the contact switch 1207 corresponds to the position of the contact plate 1206. Both the contact switch 1207 and the audible and visual alarm 1202 are electrically connected to the battery module 2. The airtight structure 11 ensures that the fire extinguisher box 1 remains relatively sealed. When the fire extinguisher body 6 leaks, the gas remains in the fire extinguisher box 1, thereby creating a negative pressure inside the fire extinguisher box 1. The negative pressure effect will drive the push plate 1205 to rise, which in turn drives the contact plate 1206 to rise through the monitoring rod 1204, so that the contact plate 1206 contacts the contact switch 1207, automatically activating the audible and visual alarm 1202, and promptly reminding the user to replace the fire extinguisher body 6 with a leak-free one, ensuring that the fire extinguisher body 6 can be used normally when needed, thus enhancing safety.

[0024] Furthermore, an anti-detachment plate 1208 is fixedly connected to the surface of the monitoring rod 1204 inside the monitoring cylinder 1203. The lower surface of the anti-detachment plate 1208 overlaps with the inner bottom wall of the monitoring cylinder 1203. The anti-detachment plate 1208 ensures that the monitoring rod 1204 will not detach from the monitoring cylinder 1203. Even if the monitoring rod 1204 moves upward, the anti-detachment plate 1208 can ensure that the monitoring rod 1204 remains in its original position when it falls.

[0025] Working principle: First, place the fire extinguisher body 6 inside the fire box 1 and place it on the support plate 5. Secure it with two straps 7. Then, insert the sealing frame 8 into the front of the fire box 1. After insertion, push the push rod 1104 to the right. This causes the push rod 1104 to move the piston 1103 to the right inside the gas cylinder 1102. The piston 1103 compresses the gas inside the gas cylinder 1102 and delivers it to the sealing airbag 1106 through the connecting pipe 1105. This causes the sealing airbag 1106 to expand inside the fire box 1, thereby compressing the inner wall of the fire box 1 and increasing the sealing effect between the sealing frame 8 and the fire box 1, ensuring that the gas does not leak. In the event of a leak, if the fire extinguisher body 6 is left unattended for an extended period and gas leaks, the gas will remain inside the fire extinguisher box 1. As the gas concentration gradually increases, a negative pressure will be generated inside the fire extinguisher box 1, which will cause the push plate 1205 to move upward. The push plate 1205 can then drive the top contact plate 1206 to rise via the monitoring rod 1204, thereby contacting the contact switch 1207. Upon expansion, the contact switch 1207 will automatically activate the audible and visual alarm 1202, thus reminding the user to replace the fire extinguisher body 6 with a leak-free one. This allows for real-time monitoring of the fire extinguisher body 6, ensuring that it can be used normally when needed, thus enhancing safety.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
