Description

[0001] AUTONOMOUS AND AUTOMATIC AEROSOL GENERATOR

[0002] Technical Field

[0003] The invention relates to an aerosol generator that can detect, extinguish or suppress a fire in an environment or place where it is located, completely autonomously and automatically, without any external connection, effect or contribution.

[0004] State of Art

[0005] In the present art, water and gaseous fire extinguishing systems are widely used among different fire extinguishing systems such as water, water mist, gas, foam, and powder.

[0006] Water fire extinguishing (sprinkler) system works with the principle that the glass bulb at the end point of a pressured pipe bursts and water flows from the sprinkler and extinguishes or suppresses the fire. It cannot be used in electrical fires. Even if the fire is extinguished, the damage caused by the water used can be great.

[0007] Gas fire extinguishing system works with the principle of discharging the gas pressurized in a container in case of fire and extinguishing the fire. These systems require regular maintenance, some of them extinguish the fire by oxygen displacement (reduction of oxygen content).

[0008] Another system that is being used in recent applications is aerosol fire extinguishing systems. Aerosol fire extinguishing systems have recently been more widely used due to their features such as being more practical and economical compared to alternative systems, being effective in different fire classes, not requiring piping, being environmentally friendly, non-toxic, and not damaging the ozone layer. Aerosol fire extinguishing systems basically work with the principle of extinguishing / suppressing the fire by the aerosol formed as a result of activating the aerosol-forming solid compound in a non-pressurized container (aerosol generator body) by different methods. n the state of the art, the process of detecting fire in an environment and activating the solid compound in the aerosol generator is performed by thermal activation, electrical activation and manual activation.

[0009] Thermal activation is performed in two ways: activation with wick and activation with thermal activator.

[0010] Activation with wick is based on the principle that a wick (thermal cord / wick) connected to the aerosol generator burns and activates the solid compound when the ambient temperature reaches a certain level. The wick activation shown in document numbered CN207950358 is an example of this. The disadvantages of wick solutions in this and similar documents are as follows;

[0011] Aerosol generators cannot be set to operate at different temperature levels (pre-set degrees).

[0012] In order for them to work, the ambient temperature must be very high (generally 1500 and above).

[0013] Since they are not made to operate at low temperature levels, they cannot detect and extinguish a fire at an early stage.

[0014] - They are very sensitive to environmental conditions, especially in environments with high humidity and salt, they may not work.

[0015] Most wicks lose their properties over time, their efficiency decreases

[0016] Activation with a thermal activator is based on the principle that a thermal activator connected externally to the aerosol generator reacts and activates the solid compound when the ambient temperature reaches a certain level. The activator shewn in document numbered KR20130042835 is an example of a thermal activator. Some thermal activators on the market are manufactured to operate at only three different temperatures (700, 95° or 1230). Other thermal activators on the market are manufactured to operate at six different temperature levels (57 ), 68D, 790, 930, 141, 1820).

[0017] The thermal activators of thermally activated aerosol generators in the present art are external and are installed to suitable aerosol generators as a separate part later. These generators perform activation / ignition by chemical reaction. They do not have built-in power sources. In thermally activated aerosol generators that use glass bulbs as heat-sensitive parts, the glass bulbs are exposed and therefore unprotected against external effects (such as impact).

[0018] Electrical activation is based on the principle of activating the aerosol generator with an electrical signal coming from an external source (e.g. fire / control panel) via a cable connected to each aerosol generator separately.

[0019] In order to perform electrical activation with the present art, an engineering system must be installed in the place where the aerosol generator will be used. This system basically works with the principle of transmitting the fire signal received from heat, smoke or flame detectors in the place to be extinguished to a fire or control panel, and activating the aerosol generators remotely with the electrical signal coming from this panel.

[0020] Disadvantages of electrically activated aerosol generators in the present art are as follows:

[0021] Electrically activated aerosol generators do not have the possibility of autonomous and automatic operation, they are dependent on external signal in all cases.

[0022] In places where electrically activated aerosol generators are used, it is essential that there is a pre-engineered fire detection (e.g. consisting of heat, smoke or flame detectors) and extinguishing system. There must be a fire panel (usually outside the place where the extinguishing will be performed, sometimes far away) where the signal from these detectors will be transmitted to, a power (electricity) source in this panel, and cables between the power source in the panel to the aerosol generators.

[0023] They do not have built-in power sources. They need an external power source. They do not work if there is no external electrical signal.

[0024] Electrical activation cannot be performed if the fire detectors do not work for any reason or if there is no electrical signal from the external power source for any reason (for example; in the event of a natural disaster (earthquake, fire, flood etc.) detectors may not work, cables between the detectors and fire / control panel may be damaged, main electrical supply cables to the panel may be damaged, cables between the panel and aerosol generators may be damaged). - The aerosol generator that is intended to be activated electrically must be part of a system. If there is no pre-engineered system in the place, electrical activation cannot be used.

[0025] - Since it is necessary to install an engineering system, both the initial investment and service & maintenance costs (detectors, cables, fire / control panels, external power source, installation, testing, commissioning and periodic maintenance costs) of the extinguishing system consisting of electrically activated aerosol generators substantially increases.

[0026] It is not feasible to use an electrically activated aerosol generator in small places (e.g. in an electrical panel, cabinet) because of its higher cost.

[0027] Manual activation is based on the principle of activating the aerosol generator by manually pulling a pin or pushing a button on the activator.

[0028] Disadvantages of manually activated aerosol generators in the present art are as follows;

[0029] Human intervention is essential for the aerosol generator to operate, the activation pin or the button on the device must be pulled or pushed manually. There is no guarantee that there will be someone in the place where / when a fire breaks out.

[0030] Even if there is someone in the place where / when a fire breaks out, the probability of that person being experienced or trained in fire intervention is very low.

[0031] - Manual activation by untrained and inexperienced people may even cause lifethreatening danger to other people located in the premises.

[0032] Due to its technology (it creates a mist like cloud in the space, reducing visibility to almost zero), aerosol fire extinguishing is not preferred to be used in places where there are many people. Aerosol fire extinguishing is mostly preferred in places where there are no or few people (technical areas, warehouses, data centers, electrical panels, electrical rooms, machine rooms, etc.). In such places, the probability of there being a person who can perform manual activation in case of fire is very low.

[0033] For the above reasons, the probability of extinguishing a fire by manually activating an aerosol generator is very low. As a result, the existence of above mentioned problems and the inadequacy of existing solutions have necessitated a development in the relevant technical field.

[0034] Purpose of the Invention

[0035] The present invention relates to an autonomous and automatic aerosol generator that eliminates the above-mentioned disadvantages and brings new advantages to the relevant technical field.

[0036] The main purpose of the invention is to provide an aerosol generator that can detect, extinguish or suppress a fire that may break out in its environment completely autonomously and automatically, without any external connection, effect or contribution.

[0040] Another purpose of the invention is to provide an aerosol generator that autonomously detects and automatically extinguishes the fire by activating the solid compound with an electrical signal. Another purpose of the invention is to provide an aerosol generator that does not require human intervention (as in manual activation) for its operation.

[0041] Another purpose of the invention is to provide an aerosol generator that solves the problem of wick aerosol generators not being able to be adjusted to detect fire at different temperature levels by using parts that are sensitive to different temperature levels and that can be adjusted to be activated at temperatures of 571}, 68:C, 79', 93'C, 141 'C, 182'C if the heat-sensitive part is a standard glass bulb.

[0042] Another purpose of the invention is to provide an aerosol generator that solves the problem of wick aerosol generators not being able to detect fire at initial stages (before the ambient temperature reaches 150 “C or above) by using a part that is sensitive to lower temperature levels (for example, 57'C or 68'C ) and prevents or reduces material and moral losses by ensuring that fires are detected and extinguished at initial stages.

[0043] Another purpose of the invention is to provide an aerosol generator that is resistant to harsh environmental conditions (such as low or high temperature environments, high humidity environments) and has a long life, thus solving the problem of wick aerosol generators being negatively or adversely affected by humid and / or salty environments or time and not being able to detect or extinguish a fire.

[0044] Another purpose of the invention is to provide an aerosol generator that can be used manually if desired and that is assembled without any heat-sensitive parts and is manually activated by pulling the safety pin.

[0045] Another purpose of the invention is to provide an aerosol generator that solves the problem of electrically activated aerosol generators not being able to operate autonomously, due to its feature of having the part required for fire detection (heat sensitive part) and the power source required for electrical activation in the same device together, simultaneously and internally (built in).

[0046] Another purpose of the invention is to provide an aerosol generator that solves the problem of electrically activated aerosol generators not being able to operate without an engineering system (such as fire detection, fire extinguishing, automation) installed in the space, as a result of its ability to perform autonomous detection with the heat- sensitive part on it and to receive the electrical energy required for activation directly from the built-in power source.

[0047] Another purpose of the invention is to provide an aerosol generator that does not require installation of a separate engineering system in the place where it is used and offers a practical and cheap solution due to its significantly lower initial investment and periodic maintenance costs.

[0048] Another purpose of the invention is to provide an aerosol generator that solves the problem of electrically activated aerosol generators not being suitable for small places and enables the use of electrically activated aerosol generators in all places, large and small, at a low cost.

[0049] Another purpose of the invention is to provide an aerosol generator that enables aerosol fire extinguishing devices to be used more widely, cheaper and more practically.

[0050] Another purpose of the invention is to provide an aerosol generator that provides a practical and very cheap solution that can be used safely even in places where there is no electricity, due to receiving the required electrical energy from its built-in power source.

[0051] Another purpose of the invention is to provide an aerosol generator that is not affected by power outages or fluctuations that may occur during natural disasters (earthquake, flood, lightning, bad weather conditions, etc.) since it is not connected to any external electrical panel and / or network system.

[0052] Another purpose of the invention is to provide an aerosol generator that can be easily placed on moving objects such as motor vehicles.

[0053] Another purpose of the invention is to provide an aerosol generator of which the heatsensitive part does not have to be a glass bulb, but can be made of any material (metal, bimetal, alloy, plastic, composite, etc.) that can deform when the ambient temperature reaches a desired or predetermined level. Another purpose of the invention is to provide a high security aerosol generator with a removable safety pin which prevents accidental operation of the aerosol generator during transportation, assembly, disassembly or service, which becomes safer with a secondary pin attached to the hole at its end, and made ready to operate by pulling the safety pin after it is safely assembled at the desired location.

[0054] Another purpose of the invention is to provide an aerosol generator designed in such a way that the built-in power source can be easily installed or replaced by people who are not experts in the art.

[0055] Another purpose of the invention is to produce an aerosol generator that can be used for many years by changing the built-in power source.

[0056] Another purpose of the invention is to provide an aerosol generator that does not continuously draw energy from the built-in power source, does not draw any electrical energy from the built-in power source when there is no fire in the environment, and draws energy from the built-in power source only after a fire in the environment is defected.

[0057] Another purpose of the invention is to provide an aerosol generator which, although not required, can at the same time use a wick also as a secondary activation tool, if desired, and in this case can be activated both electrically and with wick (dual activation), and which as primary activating tool uses the electro pyrotechnic igniter that reacts after deformation of glass bulb heat sensitive part that deforms at lower temperature levels compared to wick.

[0058] Another purpose of the invention is to provide an aerosol generator whose heatsensitive part is protected against external effects by two layers (the upper body and the cap).

[0059] In order to achieve all the purposes mentioned above and that can be derived from the detailed description, the invention is an aerosol generator that can detect and extinguish or suppress a fire that may occur in an environment or place where it is located, completely autonomously and automatically, without any external connection, effect or contribution, characterized by comprising the following;

[0098] Detailed Description of the Invention

[0099] In this detailed description, the preferred alternatives of the aerosol generator which is the subject of the invention are described only for the purpose of better understanding the subject and in a way that does not form any limiting effect.

[0100] The invention relates to an autonomous and automatic aerosol generator (1) that can detect, extinguish or suppress a fire that may break out in the environment or place where it is located, completely autonomously and automatically, without any external connection, effect or contribution.

[0101] The aerosol generator (1) which is the subject of the invention basically consists of two main parts, namely the upper body (2) and the lower body (3) located under the upper body (2). In general, the upper body (2) has the function of detecting fire, while the lower body (3) has the function of producing (generating) aerosol that extinguishes or suppresses fire.

[0102] There are window openings (4) on the upper body (2) that allow the ambient heat to freely reach the cap (5) and the heat-sensitive part (7). The said window openings (4) are arranged at least one on the upper body (2) and can be in different geometric forms such as square, rectangular, oval, round etc. A safety pin (12) is passed through the window openings (4). Inside the upper body (2), there is a cap (5) which is placed over the spring slot (8) and attached to the spring slot (8) by means of the mounting pin (10) and protects the heat-sensitive part (7) inside against external impacts, and allows the ambient heat to freely reach the heat-sensitive part (7) through the holes on it and has holes on it for the passage of the mounting pin (10).

[0103] The upper body (2) houses and protects the cap (5), the heat- sensitive part (7), the spring slot (8), the spring (9), the mounting pin (10), the upper contact part (11), the safety pin (12) and the upper conductive part (14).

[0104] The mounting pin (10), which is inserted into the two slot channels located opposite each other on the side surface of the spring slot (8) by passing through the holes on the cap (5) and the upper contact part (11), which is preferably used, has a blind end at one end and a nut (24) at the other end. The nut (24) ensures that the mounting pin (10) is attached to the cap (5) and spring slot (8), preventing it from coming out of place. The said mounting pin (10) can move up and down within the slot channel in the spring slot (8) and pulls the spring (9) upwards, ensuring that it remains compressed in the spring slot (8). The said mounting pin (10) also ensures that the cap (5), spring slot (8) and upper contact part (11) are attached to each other. The said mounting pin (10) transfers the electrical signal to the spring slot (8).

[0105] There are holes on the upper contact part (11) located in the spring slot (8) for the safety pin (12) and the mounting pin (10) to pass through. When the said upper contact part (11 ) is pushed by the spring (9) released by the deformation of the heat-sensitive part (7), it contacts upper side of the built-in power source (16) and transmits the electrical signal it receives from there to the mounting pin (10) and the spring slot (8).

[0106] Inside the cap (5), there is a heat-sensitive part (7) made of a glass bulb (thermo bulb, sprinkler bulb) which operates on the principle that the liquid inside expands and bursts with the increase in temperature, or manufactured from any material (e.g. mefal, bimetal, alloy, plastic, composite, etc.) that deforms and initiates the activation by giving the first reaction when the ambient temperature reaches the desired (predetermined) level. In Figure 2, the heat-sensitive part (7) is shown as a glass bulb, but it is not limited to this. The heat-sensitive part (7) is preferably placed inside the cap (5) with an adjustment screw (6). The said adjustment screw (6) is located on the cap (5). The said adjustment screw (6) is preferably a set screw and allows the heat-sensitive part (7) to be practically fitted between the cap (5) and the spring slot (8) with a certain torque power and to be replaced when necessary. The heat-sensitive part (7) placed inside the cap (5) by positioning it on the spring slot (8) pulls the cap (5) upwards by tightening the adjustment screw (6) on the cap (5) and while the cap (5) moves upwards, the mounting pin (10) located on the horizontal axis inside the slot channel of the spring slot (8) also moves upwards and compresses the spring (9) in the spring slot (8). Although less practical, the heat-sensitive part (7) can be placed inside the cap (5) and the spring (9) compressed without using the adjustment screw (6). In case the adjustment screw (6) is not used in the aerosol generator (1) which is the subject of the invention, first the heat-sensitive part (7) is placed between the cap (5) and the spring slot (8), the upper contact part (11) is pushed from below towards the spring slot (8) and the spring (9) is compressed, when the mounting pin (10) holes on the cap (5) and the upper contact part (11) are aligned, the mounting pin (10) is inserted and the spring (9) is kept compressed.

[0107] When the ambient temperature reaches a desired or predetermined level, the heat¬ sensitive part (7) inside the cap (5) deforms. With the deformation of the heat-sensitive part (7), the compressed spring (9) is released and pushes the upper contact part (11) which is preferably used, towards the built-in power source (16). The pushed upper contact part (11) contacts the built-in power source (16) that is located in the built-in power source socket (15) and that converts chemical energy into electrical energy. The electrical signal received from upper side of the built-in power source (16) is transmitted to the upper conductive part (14) via upper contact part (11), the mounting pin (10) and the spring slot (8).

[0108] In an alternative embodiment of the invention, the upper contact part (11) may not be present in the aerosol generator (1). In this case, the spring (9), which is compressed into the spring slot (8) by means of the mounting pin (10) and released by the deformation of the heat-sensitive part (7), directly contacts the built-in power source (16) and the electrical signal received from the upper side of the built-in power source (16) is transmitted to the upper conductive part (14) via the spring (9), the mounting pin (10) and the spring slot (8). The spring slot (8) houses and protects the spring (9) inside it and the upper contact part (11) located under the spring (9). The spring slot (8) has a recessed slot in its upper part preferably with a hole in the centre of this slot to prevent the heat-sensitive part (7) located on its upper part from displacing. At the same time, on the side surface of the spring slot (8), there are reciprocal slot channels for the passage of the mounting pin (10) and holes for the passage of the safety pin (12). The said spring slot (8) transmits the electrical signal received from the upper side of the built-in power source (16) via the upper contact part (11 ), to the upper conductive part (14), via its own body. In the aerosol generator (1) which is the subject of the invention, if it is preferred not to have a safety pin (12), there is no hole for the passage of the safety pin (12) on the side of the spring slot (8).

[0109] The spring (9) located in the spring slot (8) is normally compressed upwards by means of the mounting pin (10) in the spring slot (8) and is released by the deformation of the heat-sensitive part (7) and provides contact of the preferably used upper contact part (11) with the built-in power source (16) or if the upper contact part (11 ) is not used, the said spring (9) directly contacts the built-in power source (16) itself.

[0110] The upper conductive part ( 14) located in the upper body (2) and the lower conductive part (17) located in the lower body (3) ensure that the upper body (2) and the lower body (3) are attached to each other on one side and that the electrical signal received from upper side of the built-in power source (16) is transmitted to the electro pyrotechnic igniter (19) on the other side. The spring slot (8) is screwed onto the upper conductive part (14) located inside the upper body (2) by means of the threads formed on the inner upper surface of the upper conductive part (14). The said upper conductive part (14) and the spring slot (8) may also be in a single piece structure (monolithic). The said upper conductive part (14) is connected to the lower part of the upper body (2) by means of threads formed on its outer surface and also to the lower conductive part (17) by means of threads formed on its inner lower surface. The lower conductive part (17) is fixed to the lower body (3) by means of attaching the built-in power source socket (15) onto which it is mounted, to the lower body (3), and at the same time, it is attached to both the upper conductive part (14) and the upper body (2) by means of connecting to the lower side of upper conductive part (14) from inside, in this way, the electrical signal is transmitted between the upper conductive part (14) and the lower conductive part (17) and the upper body (2) and the lower body (3) are attached to each other. In an alternative embodiment of the invention, the built-in power source socket (15) and the lower conductive part (17) may be one-piece.

[0111] The upper conductive part (14) ensures that the electrical signal received from upper side of the built-in power source (16) is transmitted to the lower conductive part (17) in the lower body (3). The lower conductive part (17), which is fixed to the built-in power source socket (15), transmits the electrical signal it receives from the upper conductive part (14), at the junction of the upper body (2) and the lower body (3), to the electro pyrotechnic igniter (19). Thus, the electrical signal received from the upper side of the built-in power source (16), preferably by the upper contact part (11) or directly by the spring (9), is transmitted to the electro pyrotechnic igniter (19) via the mounting pin (10), the spring slot (8), the upper conductive part (14) and the lower conductive part (17), respectively.

[0112] Inside the lower body (3), there is the built-in power source socket (15), the replaceable built-in power source (16), the lower conductive part (17), the lower contact part (18), the electro pyrotechnic igniter (19), the flexible part (20), the solid compound (21) and the optionally used heat and / or flame sensitive wick (23). The said solid compound (21) is a substance that is in solid form under normal conditions, is mainly potassium carbonate based, and when activated, turns into an aerosol and extinguishes or suppresses fire in the environment in which it is released. The said wick (23) is located in the lower body (3) as a secondary activation option to activate the solid compound (21) when the ambient temperature exceeds a certain level and / or when exposed to flame. In an alternative embodiment of the invention, the wick (23) is also used, allowing the aerosol generator (1) to have both electrical activation and wick (23) activation at the same time (dual activation).

[0113] On the outer side of the lower body (3), there is at least one hole or slot for fastening the built-in power source socket (15).

[0114] The said flexible part (20) compresses due to its flexible structure, ensuring that the parts inside the lower body (3) remain fixed and immobile, and at the same time, protecting these parts against impacts and vibration.

[0115] The perforated separator (22) located in the lower body (3) divides the lower body (3) into two parts. The part between the perforated separator (22) and the lower end of the lower body (3) is the cooling part. The exit temperature of the aerosol formed by the activation of the solid compound (21) from the hole in the perforated separator (22) is high. In the section between the perforated separator (22) and the lower end of the lower body (3), the aerosol is partially cooled by the air entering through the holes on the outer side of the lower body (3). If the lower body (3) is manufactured using a method similar to plastic injection, the perforated separator (22) may also be a single structure with the lower body (3). If the lower body (3) is manufactured from a material such as a ready-made metal pipe, the perforated separator (22) can be a separate part independent of the lower body (3).

[0116] In an alternative embodiment of the invention, a heat retainer or heat absorber part can be placed between the solid compound (21) and the perforated separator (22) to ensure that some of the heat of the aerosol is absorbed or retained by the said heat retainer or heat absorber part. In this way, the temperature of the aerosol coming out of the perforated separator (22) and the aerosol generator (1) can be further reduced.

[0117] The built-in power source socket (15) located in the lower body (3) protects and insulates the built-in power source (16). There is a hole or tear on the built-in power source socket (15) for the lower conductive part (17) to pass through. There are also threads or protrusions on the side of the built-in power source socket (15) that allow the built-in power source socket (15) to engage with the holes on the lower body (3). There is a hole at the bottom of the built-in power source socket (15) for the passage of the lower contact part (18). A circlip (25) is preferably attached to the lower contact part (18) to prevent the lower contact part (18) from moving freely in the hole at the bottom of the built-in power source socket (15). It is not compulsory to use a circlip (25) for this purpose. The connection between the built-in power source socket (15) and the lower contact part (18) can be made by any method that provides mechanical interlocking (thread, pin, gear, interlace etc.). The lower contact part (18), which is attached to the built-in power source socket (15) preferably by means of a circlip(25), by passing through the aforementioned hole in the built-in power source socket (15), ensures that the electrical signal it receives from the lower end of the built-in power source (16) is transmitted to the electro pyrotechnic igniter (19).

[0118] The electro pyrotechnic igniter (19), one end of which is connected to the lower conductive part (17) and the other end to the lower contact part (18), activates the solid compound (21) when it receives electrical signal from both parts and ensures the formation / generation of the aerosol.

[0119] The heat-sensitive part (7) of the aerosol generator (1 ) deforms when the ambient temperature reaches a predetermined or desired level, releasing the compressed spring (9). The upper contact part (11), which touches the upper part of the built-in power source (16) with the push of the released spring (9), transmits the electrical signal it receives from there to the upper conductive part (14) via the mounting pin (10) and the spring slot (8). The lower conductive part (17) transmits the electrical signal it receives from the upper conductive part (14) at the junction of the upper body (2) and the lower body (3) to the electro pyrotechnic igniter (19) connected to it. The other end of the electro pyrotechnic igniter (19) receives electrical signal from the lower part of the built-in power source (16) via the lower contact part (18). As a result of the process that starts with the deformation of the heat-sensitive part (7), the electrical signal from the upper side of the built-in power source (16) is also transmitted, and both the plus (+) and minus (-) electrical signals required for the operation of the electro pyrotechnic igniter (19) are received. The solid compound (21 ) activated by the electro pyrotechnic igniter (19) changes its form and takes the form of an aerosol. The aerosol, whose temperature is partially reduced by the air entering through the holes in the lower part of the lower body (3), is released into the place or environment. Aerosol, which is preferably released into an airtight enclosure, place or environment, extinguishes or suppresses the fire in the environment with the principle of total flooding. Depending on the properties of the solid compound (21) used, different types of fires (such as types A, B, C, E and F) are extinguished or suppressed autonomously and automatically by the aerosol generator (1).

[0120] There is a safety pin (12) on the aerosol generator (1) which is the subject of the invention, in order to ensure safe use. The safety pin (12) prevents the aerosol generator (1) from accidentally operating due to deformation of the heat-sensitive part (7) for any reason during transportation, assembly, disassembly or service. The safety pin (12) is made even safer by a secondary safety pin (13) attached to its end. In this way, the safety pin (12) is prevented from coming out even if it is forced.

[0121] In the aerosol generator (1) which is the subject of the invention, the built-in power source (16) located at the junction of the upper body (2) and the lower body (3) is replaceable practically. This feature provides a secondary insurance. After the aerosol generator (1) which is the subject of the invention is safely installed in the desired location, the built-in power source (16) is attached, the secondary safety pin (13) and the safety pin (12) are pulled to make the aerosol generator (1) ready for use.
