Description

Technical Field

[0001] The utility model relates to the technical field of aerosol fire extinguishing, in particular to a handheld aerosol fire extinguishing device which can be forcibly opened. Background Art

[0002] Thermal aerosol fire extinguishing devices have been widely used due to their strong fire extinguishing ability, fast fire extinguishing speed, environmental protection, pollution-free and small size. At present, there are many mature aerosol fire extinguishers on the market, but the activation steps of these fire extinguishing products only have one insurance (latch) and one start button. When the start button fails, the entire aerosol fire extinguishing device is basically scrapped, which in disguise reduces the quality assurance of the fire extinguishing device and emergency fire extinguishing measures. Therefore, reducing the failure rate of handheld aerosol fire extinguishers has become a safety guarantee for quickly starting the device and extinguishing the fire when a fire occurs.

[0003] Specifically, aerosol fire extinguishers usually use piezoelectric ceramics and bridgeless ignition heads as the starting structure. When the piezoelectric ceramics are pressed, the bridgeless ignition head obtains a certain voltage and then stimulates the aerosol generating agent to extinguish the fire. However, due to quality or structural problems, the piezoelectric ceramics may not release enough voltage, which may cause the fire extinguisher to fail to start normally. If the fire extinguisher does not have a backup starting measure, it may cause the fire extinguisher to fail to start at all and fail to extinguish the fire. Summary of the invention

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a handheld aerosol fire extinguishing device that can be forced to open. When a failure occurs in the start button, the forced start device can be started to achieve the purpose of normal start of the fire extinguisher and effective fire extinguishing.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The diagram is a structural diagram of a handheld aerosol fire extinguishing device that can be forcibly opened. DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1 As shown, a handheld aerosol fire extinguishing device that can be forced to open includes a cylinder 1 and a fire extinguishing agent column 2 arranged inside the cylinder 1, the fire extinguishing agent column 2 cooperates with a starting component 3, the ignition end of the fire extinguishing agent column 2 is connected to two electric ignition heads 3.1 of the starting component 3, one of the electric ignition heads 3.1 is connected to a piezoelectric ceramic 3.2, a starting button 3.3 is provided at the pressing end of the piezoelectric ceramic 3.2, and the other electric ignition head 3.1 is connected to a battery 3.4 and a forced starting device 3.5.

[0019] Preferably, a nozzle 5 is provided on the surface of the front cover 4 of the cylinder 1 .

[0020] Preferably, a protective plug 6 is also attached to the surface of the nozzle 5. With this design, during the storage and transportation of the fire extinguishing device, moisture in the air can be prevented from entering the interior of the cylinder 1 through the nozzle 5 to cause the fire extinguishing agent column 2 to absorb moisture. At the same time, during the fire extinguishing process, the protective plug 6 can automatically fall off after being pressed, without affecting the spraying process.

[0021] Preferably, a silicone sleeve 7 for heat insulation is provided between the fire extinguishing agent column 2 and the inner wall of the cylinder 1 .

[0022] Preferably, the area between the ignition end face of the fire extinguishing agent column 2 and the front cover 4 is filled with a coolant 8. After the coolant 8 is provided, the high-temperature fire extinguishing substance generated by the fire extinguishing agent column 2 can be cooled, so that after the fire extinguishing substance is sprayed out from the nozzle 5, the temperature at the nozzle 5 of the fire extinguishing device will not be too high.

[0023] Preferably, the fire extinguishing agent column 2 is a columnar structure formed by pressing aerosol generating agent powder. The aerosol generating agent pressed into a columnar structure burns more slowly than the powdered aerosol generating agent, which can ensure the continuity of the release of the fire extinguishing material.

[0024] Preferably, a protective shell 9 is further provided on the outer side of the cylinder 1. The protective shell 9 can facilitate the hand-holding process and also prevent the high temperature generated by the combustion of the fire extinguishing agent column 2 from causing burns to the hands.

[0025] Preferably, the ignition end of the fire extinguishing agent column 2 is provided with an ignition powder bag 2.1, and the ignition powder bag 2.1 covers two electric ignition heads 3.1. In this embodiment, the handheld start method of the handheld aerosol fire extinguishing device is: press the start button 3.3, thereby pressing the piezoelectric ceramic 3.2, and the piezoelectric ceramic 3.2 generates current so that the electric ignition head 3.1 ignites the ignition end face of the fire extinguishing agent column 2, thereby realizing the start process; and after the ignition powder bag 2.1 (with aerosol generating agent powder inside) is set, the powdered aerosol generating agent powder inside the ignition powder bag 2.1 is easier to ignite, thereby making it easier to ignite the ignition end face of the fire extinguishing agent column 2, so the ignition powder bag 2.1 here plays an energy amplification effect.

[0026] Preferably, the forced starting device 3.5 comprises a fixed contact part 3.5.1 and a movable contact part 3.5.2 connected to the circuit where another electric ignition head 3.1 is located. Before starting, the fixed contact part 3.5.1 and the movable contact part 3.5.2 are separated from each other, and one end of the movable contact part 3.5.2 is connected to the operation button 3.5.3. In this embodiment, by pressing the operation button 3.5.3, the movable contact part 3.5.2 can be brought close to and contacted with the fixed contact part 3.5.1, so that the circuit where the electric ignition head 3.1 is located is connected, and the battery 3.4 supplies power to the electric ignition head 3.1, so that the electric ignition head 3.1 ignites the ignition end face of the fire extinguishing agent column 2, and the starting process is realized; in this embodiment, the circuit selects a soft wire structure that can be bent and folded, so that the movable contact part 3.5.2 connected to the circuit can move smoothly.

[0027] Preferably, a safety pin 3.6 is inserted into the movable contact portion 3.5.2 and the start button 3.3. The safety pin 3.6 can prevent misoperation. Before extinguishing a fire, the safety pin 3.6 can be pulled out to enable the start button 3.3 and the operation button 3.5.3 to be pressed and moved.

[0028] The working principle of this embodiment is as follows:

[0029] When a fire occurs, the personnel first pull out the safety pin 3.6, and then press the start button 3.3, thereby pressing the piezoelectric ceramic 3.2, and the piezoelectric ceramic 3.2 generates current so that one of the electric ignition heads 3.1 ignites the ignition end face of the fire extinguishing agent column 2, and the start process is realized. The fire extinguishing agent column 2 burns layer by layer from the ignition end face and releases the fire extinguishing material, and then is sprayed out from the nozzle 5 to carry out the fire extinguishing process;

[0030] When the start button 3.3 fails, by pressing the operating button 3.5.3, the movable contact part 3.5.2 can be brought close to and contacted with the fixed contact part 3.5.1, so that the circuit where the other electric ignition head 3.1 is located is connected, and the battery 3.4 supplies power to the other electric ignition head 3.1, so that the electric ignition head 3.1 ignites the ignition end face of the fire extinguishing agent column 2, thereby completing the starting process.

[0031] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
