[0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a bottle-type fire extinguisher. Background Art
[0002] Bottle fire extinguishers are one of the common firefighting equipment, usually stored in public places or places where fires may occur. They are mainly composed of a liquid storage bottle and a container valve that controls the discharge of fire extinguishing agents. Different types of fire extinguishers are filled with different ingredients, designed to extinguish fires for different causes. In order to achieve remote control of fire extinguishers, some existing fire extinguishers are equipped with an electromagnetic drive device connected to the container valve, which can activate the electromagnetic drive through a remote signal to open the container valve to release the fire extinguishing agent.
[0003] In most cases, bottle-type fire extinguishers can be reused according to the amount of fire extinguishing agent built in, which makes the existing container valve design quite complicated. Specifically, this type of container valve is usually equipped with an outlet connecting the tank to the outside world, and a valve assembly that can move up and down at the outlet to open or close the outlet. However, whether it is manual operation or electric operation mode, it is required that the container valve is equipped with a power system that automatically returns the valve core to the initial position, and a sealing system that ensures the sealing performance of the valve core. This complex structure not only has high requirements on the reliability and service life of the valve body, but also greatly increases the manufacturing cost of the fire extinguisher.

DETAILED DESCRIPTION
[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0028] like Figures 1 to 6 As shown, a bottle-type fire extinguisher includes a bottle body 100 , a drainage joint 200 , a movable structure 300 , an electromagnetic driver 400 , a siphon 500 , an explosion-proof disc 600 , a pressure monitoring assembly 700 and a protective base 800 .
[0029] like Figures 1 to 6 As shown, a bottle-type fire extinguisher comprises:
[0030] The bottle body 100 is provided with a filling interface 110 for filling the fire extinguishing agent;
[0031] The fire extinguishing agent release mechanism includes a drainage component and an electromagnetic driver 400. The drainage component includes a drainage joint 200 and a movable structure 300. One end of the drainage joint 200 is detachably connected to and communicated with the filling interface 110, and the other end is detachably connected to and communicated with the electromagnetic driver 400. The drainage joint 200 is provided with a first interface 210 connected to the outside. The movable structure 300 includes a blocking member 310 rotatably provided on the first interface 210. After the electromagnetic driver 400 is started, a pressure difference can be generated in the drainage joint 200.
[0032] When a pressure difference is generated in the drainage joint 200, the barrier 310 rotates away from the first interface 210 under the action of the pressure difference, so that the first interface 210 is in a state of communication with the outside, and the fire extinguishing agent can be released through the first interface 210; when the pressure difference in the drainage joint 200 is eliminated, the barrier 310 rotates toward the first interface 210 or remains stationary, and forms a blockage on the first interface 210, so that the first interface 210 is in a closed state to prevent the fire extinguishing agent from being released through the first interface 210. This design replaces the traditional container valve by providing a drainage assembly including the drainage joint 200 and the movable structure 300, and the movable structure 300 includes a barrier 310 that is rotatably matched with the drainage joint 200. At the same time, by using the principle of pressure difference, the drainage assembly can support multiple uses of the fire extinguisher while taking into account the sealing performance. This design greatly simplifies the overall structure of the fire extinguisher, reduces the production cost and process complexity of the fire extinguisher, and also enhances the convenience of fire extinguisher maintenance. In addition, compared with a complex valve body structure, the barrier member 310 has a higher design reliability and a longer service life.
[0033] Specifically, if Figures 1 to 3 As shown, in this embodiment, the bottle-type fire extinguisher is provided with a bottle body 100, a drainage assembly detachably connected to the bottle body 100, and an electromagnetic driver 400 detachably connected to the drainage assembly from left to right. The design of the detachable connection of the three effectively improves the convenience of disassembly, assembly and maintenance of the fire extinguisher.
[0034] In this embodiment, the bottle body 100 is cylindrical and is mainly used to store fire extinguishing agent. The two ends of the bottle body 100 have arc parts 101. The arc design effectively alleviates the stress concentration phenomenon that may occur at the two ends of the conventional bottle body 100, making the bottle body 100 more evenly stressed, thereby extending the service life of the bottle body 100.
[0035] In this embodiment, a cylindrical protective base 800 is sleeved on one end of the back filling interface 110 of the bottle body 100, and the diameter of the protective base 800 is larger than the diameter of the bottle body 100. The design of the protective base 800 not only allows the bottle body 100 to remain in a vertical state during transportation, but also protects the arc portion 101 from external impact, significantly improving the safety and reliability of the bottle body 100.
[0036] In this embodiment, the inner wall of the bottle body 100 is provided with an anti-corrosion coating, which extends along the length direction of the bottle body 100, so that the bottle body 100 can allow different types of fire extinguishing agents (such as liquid fire extinguishing agents or gas fire extinguishing agents) to be stored in turn, so that users can choose different types of fire extinguishing agents according to their needs, effectively improving the flexibility of users in selecting fire extinguishing agents.
[0037] like Figure 3 , Figure 5 , Figure 6 As shown in this embodiment, the bottle body 100 is provided with a filling interface 110 for filling the fire extinguishing agent at one end near the drainage assembly, and the filling interface 110 is threaded and threadedly connected with the drainage joint 200. This not only ensures the reliability of the connection between the bottle body 100 and the drainage joint 200, but also improves the convenience of filling the fire extinguishing agent.
[0038] In this embodiment, a hollow siphon 500 is further provided inside the bottle body 100, one end of which is detachably inserted into the drainage joint 200, and the other end of which extends to the bottom of the bottle body 100 away from the drainage joint 200, and forms a bent portion 510 inclined toward the side wall of the bottle body 100. This design allows the fire extinguishing agent in the bottle body 100 to be fully utilized, and further allows the bottle body 100 to meet the user's requirements for placement in different directions (such as vertical arrangement or horizontal arrangement), expanding the applicable scenarios of the fire extinguisher.
[0039] In this embodiment, the end of the siphon tube 500 inside the drainage joint 200 is provided with a bonded circular explosion relief piece 600, whose diameter is adapted to the diameter of the siphon tube 500, and forms a blockage for the siphon tube 500, and the explosion relief piece 600 can be broken under the action of the air pressure difference. As a result, when the air pressure difference is generated in the drainage joint 200, the fire extinguishing agent can enter the drainage joint 200 through the siphon tube 500, and then be released through the first interface 210 to achieve the release of the fire extinguishing agent. The design of the explosion relief piece 600 can prevent the fire extinguishing agent from flowing into the drainage joint 200 due to transportation vibration during transportation, causing the fire extinguishing agent to be accidentally sprayed. The reliability of the fire extinguisher during transportation and storage is effectively improved.
[0040] Preferably, in this embodiment, the siphon tube 500 is threadedly connected to the drainage joint 200 through the filling interface 110, and a sealing gasket 610 is also provided between the siphon tube 500 and the filling interface 110, which effectively ensures the airtightness and reliability of the connection between the siphon tube 500 and the bottle body 100 and the drainage joint 200.
[0041] In this embodiment, the drainage assembly includes a drainage joint 200 detachably connected and connected to the filling interface 110 and the electromagnetic driver 400, and a movable structure 300 provided on the drainage joint 200. The drainage joint 200 is mainly used to guide and discharge the fire extinguishing agent, and is provided with a plurality of interfaces located in different directions, so that the drainage joint 200 can realize the directional release of the fire extinguishing agent.
[0042] In this embodiment, the drainage joint 200 is provided with a first interface 210 serving as a fire extinguishing agent injection port, and a swivel joint 900 is detachably provided on the first interface 210. The swivel joint 900 is communicated with the first interface 210, and has a connector that can be rotated relative to the first interface 210, so that the user can rotate the connector according to the needs of use, thereby realizing flexible connection between the drainage joint 200 and other components (such as fire sprinklers or pipes), and effectively facilitating the disassembly and assembly of other components.
[0043] Preferably, in this embodiment, the rotary joint 900 is threadedly connected to the first interface 210, and there is a gap between the rotary joint 900 and the first interface 210 for the blocking member 310 to rotate, which effectively ensures the reliability of the rotation of the blocking member 310. At the same time, in order to ensure the airtightness of the connection between the rotary joint 900 and the first interface 210, a sealing ring (not shown in the figure) is provided between the rotary joint 900 and the first interface 210.
[0044] In this embodiment, the drainage joint 200 is further provided with a third interface 240 and a fourth interface 250 respectively connected to the first interface 210, and the third interface 240 and the fourth interface 250 are arranged opposite to each other. Among them, the outer wall of the third interface 240 is provided with a thread, which is threadedly connected to the filling interface 110, and the inner wall of the third interface 240 is provided with a thread, which is threadedly connected to the siphon 500; the fourth interface 250 is threadedly connected to the electromagnetic driver 400, and a gate knife (not shown in the figure) of the electromagnetic driver 400 can be inserted. When the gate knife is inserted into the fourth interface 250, the fourth interface 250 can be connected to the outside for deflation, thereby generating an air pressure difference inside the drainage joint 200. Preferably, a sealing ring (not shown in the figure) is provided between the third interface 240, the fourth interface 250 and the drainage joint 200. This design not only ensures the reliability and convenience of the connection between the drainage joint 200 and the bottle body 100 and the electromagnetic driver 400, but also ensures the convenience of maintenance.
[0045] like Figure 1 , Figure 2 , Figure 6 As shown, in this embodiment, the drainage joint 200 also includes a second interface 220 that is connected to the inside of the drainage joint 200. The second interface 220 is arranged on the opposite side of the first interface 210, and a pressure monitoring component 700 is arranged thereon. The pressure detection component includes a pressure sensor 710 that is threaded or welded to the second interface 220, and a pressure gauge 720 that is arranged on the pressure sensor 710 away from the second interface 220. The pressure gauge 720 is threaded or welded to the pressure sensor 710, and the pressure sensor 710 is connected to the control system (not shown in the figure). The design allows the user to intuitively view the pressure value inside the drainage joint 200 through the pressure gauge 720, and can also remotely view the pressure value inside the drainage joint 200 through the control system (not shown in the figure). Real-time monitoring of the pressure value inside the drainage joint 200 is achieved, which effectively improves the convenience of users viewing the pressure value of the drainage joint 200, and also facilitates users to replenish gas to the drainage joint 200 in time.
[0046] It is worth noting that the pressure gauge 720 is connected to the pressure sensor 710 via a retractable elastic connection, which allows the user to pull the pressure gauge 720 according to the needs of the maintenance environment, thereby effectively improving the convenience for the user to view the pressure gauge 720 .
[0047] In this embodiment, the drainage joint 200 is also provided with at least two gas charging interfaces 230, which are at an angle of 90° and are respectively connected to the first interface 210, so that the user can charge the drainage joint 200 through any gas charging interface 230 as needed, so that the drainage joint 200 can release the fire extinguishing agent by using the air pressure difference, which effectively simplifies the overall structure of the drainage component. In addition, the design of the two gas charging interfaces 230 not only enables the user to perform charging operations from different directions, or connect two charging devices at the same time, effectively improving the flexibility of operation and charging speed; it also enables gas charging through another gas charging interface 230 after one gas charging interface 230 fails, effectively improving the reliability of the drainage component.
[0048] In this embodiment, the two inflation interfaces 230 are respectively provided with detachable blocking members 231 to ensure the air tightness of the drainage joint 200 in a non-inflated state.
[0049] like Figures 1 to 4 , Figure 6As shown, in this embodiment, the movable structure 300 includes a blocking member 310 rotatably disposed on the first interface 210. The blocking member 310 is in the shape of a round block and includes a left baffle 311 and a right baffle 312 rotatably disposed on the first interface 210. The left baffle 311 and the right baffle 312 have the same structure and are arranged relative to each other. The first interface 210 is blocked and opened by performing a rotating opening and closing movement. This design ensures the sealing of the drainage joint 200 in the non-working state and ensures that the fire extinguishing agent can be released smoothly through the first interface 210 in the working state.
[0050] It should be noted that the barrier 310 can also be set as an integrated structure. Preferably, in this embodiment, the barrier 310 is set as a split left baffle 311 and a right baffle 312 so as to cooperate with the double magnetic attraction part 320 to improve the sealing effect and reliability of the barrier 310.
[0051] In this embodiment, the first interface 210 is provided with a mounting edge 211, the left baffle 311 and the right baffle 312 are respectively bonded to the mounting edge 211, and are respectively provided with a flexible portion 313, and the distance between the flexible portion 313 and the center line of the first interface 210 is adapted to the radius of the first interface 210, and when the left baffle 311 and the right baffle 312 rotate, the flexible portion 313 is elastically bent toward or away from the first interface 210. That is, the design of the flexible portion 313 can make the left baffle 311 and the right baffle 312 reliably return to the initial position after the air pressure difference is eliminated, thereby preventing the leakage of the fire extinguishing agent. The air tightness of the fire extinguisher in a non-working state and the reliability of multiple uses are effectively guaranteed. In addition, the design of the flexible portion 313 can utilize the characteristics of elastic deformation to reduce stress concentration and increase the service life of the left baffle 311 and the right baffle 312.
[0052] In this embodiment, the movable structure 300 includes a magnetic attraction portion 320 provided on the barrier 310, and the adsorption force of the magnetic attraction portion 320 is less than the pressure exerted on the barrier 310 under the action of the air pressure difference; when an air pressure difference is generated inside the drainage joint 200, the barrier 310 rotates in a direction away from the first interface 210 under the action of the air pressure difference, so that the fire extinguishing agent can be released through the first interface 210; when the air pressure difference in the drainage joint 200 is eliminated and the angle between the barrier 310 and the horizontal plane of the first interface 210 is greater than 0, the barrier 310 rotates in a direction close to the first interface 210 under the adsorption force of the magnetic attraction portion 320 and the elastic recovery force of the flexible portion 313, or when the air pressure difference in the drainage joint 200 is eliminated and the angle between the barrier 310 and the horizontal plane of the first interface 210 is less than or equal to 0, the barrier 310 remains stationary under the action of the adsorption force of the adsorption portion. Thus, the first interface 210 is blocked, so that the first interface 210 is in a closed state, thereby preventing the fire extinguishing agent from being released through the first interface 210. This design enables the drainage joint 200 to support the reuse of the fire extinguisher while taking into account the air tightness and the stability of the release of the fire extinguishing agent. This not only simplifies the overall structure of the fire extinguisher, but also reduces the production cost of the fire extinguisher.
[0053] In this embodiment, the magnetic attraction portion 320 includes a first magnetic attraction portion 321 disposed on the left baffle 311, and a second magnetic attraction portion 322 disposed on the right baffle 312. When the first magnetic attraction portion 321 and the second magnetic attraction portion 322 are attached, the left baffle 311 and the right baffle 312 cooperate to form a blockage for the first interface 210. The design of the double magnetic attraction portion 320 not only ensures the reliability of the attachment of the left baffle 311 and the right baffle 312, but also disperses the force strength of the left baffle 311 and the right baffle 312, thereby ensuring the stability of the connection between the left baffle 311 and the right baffle 312 and the first interface 210.
[0054] In this embodiment, the magnetic attraction portion 320 is a magnet block, a magnet sheet, or a magnet coating.
[0055] In this embodiment, the movable structure 300 further includes a sealing portion 330, which includes a first sealing portion 331 connected to the first magnetic portion 321, and a second sealing portion 332 connected to the second magnetic portion 322. When the left baffle 311 and the right baffle 312 form a blockage on the first interface 210, the first sealing portion 331 and the second sealing portion 332 are closely connected. This design can not only ensure the airtightness when the left baffle 311 and the right baffle 312 are closed, but also reduce the friction between the first magnetic portion 321 and the second magnetic portion 322, thereby improving the service life.
[0056] Preferably, in this embodiment, the sealing portion 330 is made of sealing materials such as rubber or silicone.
[0057] In this embodiment, the electromagnetic driver 400 has both electromagnetic driving function and manual control function, and is a commonly used electromagnetic driving device in the field of fire extinguishers. Since it belongs to an existing structure, its specific structure is not described in detail in this embodiment. By configuring the electromagnetic driver 400, the fire extinguisher of the present application can realize both remote control of the release of the fire extinguishing agent and manual control.
[0058] The working principle of the bottle-type fire extinguisher provided in this embodiment is that when a fire extinguishing operation is required, the electromagnetic driver 400 can be remotely started or the manual operation button of the electromagnetic driver 400 can be manually pressed to make the gate of the electromagnetic driver 400 extend into the interior of the drainage joint 200, thereby connecting the drainage joint 200 with the outside, so that the gas in the drainage joint 200 is released; at this time, an air pressure difference is formed between the drainage joint 200 and the outside, thereby causing the barrier 310 to rotate outward, and at the same time the explosion-proof plate 600 ruptures, and the fire extinguishing agent in the bottle body 100 flows into the drainage joint 200 under the action of the air pressure difference between the bottle body 100 and the drainage joint 200, and is released through the first interface 210. When the fire is extinguished, the electromagnetic driver 400 is powered off or the manual operation button is released to stop the drainage joint 200 from leaking air, so that the air pressure in the drainage joint 200 is gradually balanced with the external air pressure under the continuous air supply of the siphon tube 500. After the air pressure difference in the drainage joint 200 is eliminated, the barrier 310 is rotated to the initial position toward the first interface 210 under the action of the adsorption force of the magnetic part 320 and the elastic deformation force of the flexible part 313, and the first interface 210 is blocked to prevent the fire extinguishing agent from leaking when not in operation.
