Abstract

The present invention basically can detect whether there is a fire on the site where a detector has been installed using a smoke detection method, and add or change auxiliary sensors capable of detecting a fire using a method other than the smoke detection method in an expanding manner. Therefore, even if the characteristics of the site where the fire detector has been installed are changed, the fire detection characteristics of a previously installed a fire detector can be changed to match the changed characteristics of the site while the previously installed fire detector is maintained to be unchanged without needing to change the previously installed fire detector into a fire detector having different detection characteristics. The occurrence of a fire can be detected accurately using, in a combined manner, the smoke detection information of a smoke detection sensor and the detection information of the auxiliary sensors added or changed in an expanding manner. A temperature sensor for detecting the occurrence of a fire by detecting the temperature can be installed while being spaced by a certain distance from a control circuit of the detector, so heat generated from the control circuit of the detector is excluded from a target for temperature detection to enable the temperature sensor to detect only heat caused by a fire, thereby preventing inaccurate temperature detection caused by heat generated from the control circuit of the detector. The present invention comprises: a detector housing (100); a sensor expansion control part (200); and a smoke detection part (300).

Description

A combined fire detector that is possible to expand sensors}

The present invention relates to a sensor-extended complex fire detector, and more particularly, to detect a fire at a site where the detector is installed by using a smoke detection method, but to provide auxiliary sensors capable of detecting a fire in a method other than the smoke detection method. The present invention relates to a fire detector that can be added or changed in an expandable type and can accurately detect the occurrence of a fire by using smoke detection information of a smoke sensor and detection information of an auxiliary sensor that is added or changed in an expandable manner.

In modern society, safety accidents due to various industrial accidents are increasing along with industrial development. Among them, fire accidents require special attention because they cause many human and property damages.

In particular, fire accidents that occur at industrial sites cause large-scale fire accidents due to raw materials and chemicals used in industrial sites if the initial response fails, causing many human casualties and property damage.

In a factory that produces batteries as one of the industrial sites, various tests (charge/discharge test, heat resistance test, etc.) are conducted on the produced batteries, and fire accidents due to battery explosions frequently occur during various tests on batteries.

In general, fire detectors are installed in various industrial sites to detect whether or not a fire has occurred. There are various types of fire detectors for detecting fire.

However, in the case of a fuel temperature detector that determines the occurrence of a fire by detecting smoke and temperature, the temperature sensor installed in the fuel temperature detector is installed adjacent to the detector control circuit. It can even detect heat that is too low, which can lead to the possibility of inaccurate temperature sensing.

In addition, various types of fire detectors should be installed according to the characteristics of the fire detector installation site. Conventional fire detectors include smoke detectors that detect fire by detecting smoke, temperature detectors that detect fire by detecting temperature, smoke and It is specialized and produced as a fuel temperature detector that detects the occurrence of fire by detecting temperature and a flame detector that detects the occurrence of fire by detecting flame. There was a problem of the cost of having to change and install all of the fire detectors.

Therefore, it is necessary to install a temperature sensor that detects fire by detecting temperature at a certain distance from the detector control circuit, and even if the characteristics of the fire detector installation site are changed, it is necessary to change the existing fire detector to a fire detector with a different detection characteristic. There is a need to change the fire detection characteristics of the existing installed fire detectors to suit the changed field characteristics while maintaining the existing installed fire detectors.

For example, it should be possible to change from a smoke and temperature sensing feature to a smoke and flame sensing feature, or from a smoke and temperature sensing feature to a smoke and humidity sensing feature.

Therefore, the present invention is an auxiliary sensor capable of basically detecting whether or not a fire occurs at a site where a detector is installed using a smoke detection method and detecting a fire in a method other than the smoke detection method so as to solve conventional problems or respond to necessity. We propose a fire detector that enables additional or modified installation of smoke detectors in an expandable manner and accurately detects the occurrence of a fire by using the smoke detection information of a smoke sensor and the detection information of an auxiliary sensor additionally or modified in an expandable manner.

In order to form a space, as shown in FIG. 3, it is configured to include an upper housing body 111 and a lower housing body 112 coupled to each other.

The chamber exposure port 120 is configured to be formed in the center of the upper surface of the housing body 110 (the center of the upper housing body 111) so that the smoke sensing chamber 310 can be exposed to the outside, as shown in FIG. Likewise, the smoke detection chamber 310 of the smoke detection unit 300 is exposed to the outside through the chamber exposure opening 120 .

That is, when the smoke detection unit 300 is installed in the inner space of the housing body 110, the smoke detection chamber 310 of the smoke detection unit 300 is exposed to the outside through the chamber exposure opening 120, Smoke generated by a fire is introduced into the smoke detection chamber 310 exposed to the outside.

The indicator light exposure hole 130 is formed in plurality on one side of the upper surface of the housing body 110 (one side of the upper surface of the upper housing body 111) so that the status indicator light 220 can be exposed to the outside, and the sensor is extended. When the control unit 200 is installed in the inner space of the housing body 110, as shown in FIG. 5, a plurality of status indicator lights 220 are exposed to the outside through the indicator light exposure hole 130 to monitor the state of the detector. display

On the other hand, the sensor expandable composite fire detector of the present invention (10) should be able to individually set the detector ID and detector grade.

The detector ID is sensor identification information that enables a manager to identify which detector fire is detected when a fire detection signal is transmitted to the outside, and the detector grade is grade information about the smoke detection sensitivity of the detector.

For example, if the detector level is set to type 1, a fire detection signal is generated when 5% of smoke is detected, and if it is set to type 2, a fire detection signal is generated when 15% of smoke is detected. That is, the higher the grade, the more the fire detection signal is generated even with less smoke.

Components that allow the individual setting of the sensor ID and sensor level are the sensor ID setting unit 230 and the sensor level setting unit 240 of the sensor expansion control unit 200, which will be described later, and the user uses the sensor ID setting unit 230 and the sensor By manipulating the level setting unit 240, the sensor ID and sensor level can be individually set.

As shown in FIG. 3, an operation window on the lower surface of the housing body 110 (lower surface of the lower housing body 112) so that the user can operate the sensor ID setting unit 230 and the sensor level setting unit 240. A setting unit exposure port 180 that functions is formed.

The setting unit exposure port 180 may be formed of one or two as shown in FIG. 3, and when the sensor expansion control unit 200 is installed in the inner space of the housing body 110, FIG. 5 , the sensor ID setting unit 230 and the sensor level setting unit 240 are exposed and seen through the setting unit exposure opening 180, and the user sets the sensor ID through the setting unit exposure opening 180. By manipulating the unit 230 and the sensor level setting unit 240, the sensor ID and sensor level can be individually set.

The sensor extension control unit 200 is installed inside the detector housing 100, displays the state of the detector, allows the ID and grade of the detector to be set, allows the detachable external sensor to be extended and installed, and fire detection signal It is a configuration that transmits the detection information of the external sensor to the outside.

Therefore, the user can expand and install external sensors (temperature detection sensor, humidity detection sensor, flame detection sensor, etc.) suitable for the sensor installation site situation through the sensor expansion control unit 200 in a detachable manner.

Specifically, the sensor extension control unit 200, as shown in FIG. 4,

A control board 210 on which the control circuit 211 is designed;

Under the control of the control circuit 211, a plurality of status indicator lamps 220 installed on the control board 210 to turn on to indicate the sensor operation status, sensor communication status, and fire detection status;

A sensor ID setting unit 230 installed on the control board 210 so that a user can set a sensor ID;

A sensor level setting unit 240 installed on the control board 210 so that a user can set a sensor level;

A power/communication terminal 250 installed on the control board 210 so that the power/communication cable connector can be connected to the control board 210;

A sensor expansion terminal 260 installed on the control board 210 so that the external sensor can be detachably coupled to the control board 210 for the extension installation of an external sensor that detects a fire in a method other than the smoke detection method It is characterized in that it includes.

The control board 210 is a kind of board-type PCB board on which the control circuit 211 is designed, and as shown in FIG. 2, the smoke detection unit 300 is attached and installed to the control board 210, as shown in FIG. As described above, a plurality of status indicators 220, a sensor ID setting unit 230, a sensor level setting unit 240, a power/communication terminal 250, and a sensor expansion terminal 260 are installed. A detailed description of the function of the control circuit 211 designed on the control board 210 will be described later.

As shown in FIG. 4, the status indicator light 220 is lit up to display the sensor operation status, sensor communication status, and fire detection status under the control of the control circuit 211, on the control board 210. As a configuration, when the sensor expansion control unit 200 is installed in the inner space of the detector housing 100, as shown in FIG. 5, through the indicator light exposure hole 130 formed in the detector housing 100 is exposed to indicate the state of the sensor. In particular, it is preferable to apply an LED lamp to the status indicator 220.

If a fire breaks out in an abnormal state of the detector, it can lead to a serious accident, so the manager can visually check whether the detector is powered on normally, communication with the outside is normal, and whether the fire has been detected. A plurality of status indicator lamps 220 are turned on to display the state of the detector so that it can be confirmed.

A plurality of status indicators 220 are at least a power status indicator that indicates whether or not power is normally supplied to the detector, a communication status indicator that indicates whether communication with the outside is normal, and a fire state that indicates whether or not a fire has been detected. Indicator lights may be included.

As shown in FIG. 4, the sensor ID setting unit 230 is installed on the control board 210 so that the user can set the sensor ID. When installed in the inner space, as shown in FIG. 5, it is exposed to the user through the setting unit exposure hole 180 formed in the detector housing 100, and the user can set the sensor ID through the setting unit exposure hole ( 180) to operate the sensor ID setting unit 230.

For example, a detector installed on the 1st floor of a battery storage rack, which stores batteries and can perform various durability tests, has an ID of #01, and a detector installed on the 2nd floor of a battery storage rack has an ID of #02. If you need to set ID #03 for the detector installed on the 3rd floor of the battery storage rack and ID #0n for the detector installed on the n floor of the battery storage rack, the user needs to set the ID on the 1st floor of the battery storage rack. By manipulating the sensor ID setting unit 230 of the sensor to be installed, the corresponding sensor is set to ID #01, and by manipulating the detector ID setting unit 230 of the sensor installed on the second floor of the battery storage rack, the corresponding sensor is set to ID # 02, operate the detector ID setting unit 230 of the detector installed on the 3rd floor of the battery storage rack to set the corresponding detector to ID #03, and set the detector ID of the detector installed on the n floor of the battery storage rack. By manipulating the unit 230, the corresponding sensor is set to ID #0n.

At this time, it is preferable to apply the dip switch method as shown in FIG. 4 so that the sensor ID setting unit 230 can set the sensor ID using the on-off binary method.

The sensor expandable composite fire detector of the present invention (10) should be able to initially set the sensor ID, and should be able to change and set the initially set sensor ID as needed.

In particular, the reason why the initially set sensor ID can be changed as needed is that a sensor initially installed in a specific site can be installed in another site as needed. In this case, a situation may occur in which an ID, which is sensor identification information, needs to be changed according to a changed site.

The sensor level setting unit 240 is configured to be installed on the control board 210 so that the user can set the sensor level. When the sensor extension control unit 200 is installed in the inner space of the sensor housing 100, FIG. 5 As shown in, it is exposed to the user through the setting unit exposure hole 180 formed in the detector housing 100, and the user sets the sensor level through the setting unit exposure opening 180 to set the sensor level. 240 will be manipulated.

For example, a detector installed in a site requiring the installation of a first-class detector is rated as Class 1, a detector installed at a site requiring the installation of a Class 2 detector is classified as Class 2, and a detector installed at a site requiring the installation of a Class 3 detector is rated as Class 2. It is necessary to set the class of the detector to 3 types. The user operates the detector level setting unit 240 of the sensor installed in the field where the 1st type detector needs to be installed to set the level of the corresponding sensor to 1st type, and the 2nd type detector By manipulating the sensor level setting unit 240 of the sensor installed in the field requiring installation, the level of the corresponding sensor is set to 2 types, and the sensor level setting unit 240 of the sensor installed in the field requiring 3 type sensor installation By operating it, the grade of the corresponding sensor is set to 3 types.

At this time, it is preferable to apply the dip switch method as shown in FIG. 4 so that the sensor level setting unit 240 can also set the sensor level using the on-off binary method.

The detector grade is grade information about the smoke detection sensitivity of the detector. For example, if the detector grade is set to type 1, a fire detection signal is generated when 5% of smoke is detected, and if set to type 2, smoke is detected. When 15% is detected, a fire detection signal is generated. That is, the higher the grade, the more the fire detection signal is generated even with less smoke.

The sensor expandable composite fire detector of the present invention (10) should be able to initially set the detector grade and change the initially set detector grade as needed.

In particular, the reason why the initially set sensor class can be changed as needed is that a sensor initially installed in a specific site can be installed in another site as needed.

For example, it may be a case of moving and installing a sensor installed in a site requiring installation of a first-class detector to a site requiring installation of a second or third-type detector.

In this case, a situation may occur in which the sensor level needs to be changed according to the changed site. To this end, the sensor level initially set through the sensor level setting unit 240 can be changed and set as necessary.

The power/communication terminal 250 is a kind of connecting terminal installed on the control board 210 as shown in FIG. 4 so that the power/communication cable connector can be connected to the control board 210, and the sensor expansion controller ( 200) is installed in the inner space of the detector housing 100, as shown in FIG. 5, it is exposed to the outside through the first terminal exposure hole 140 formed in the detector housing 100, and the cable connector for power/communication allow it to connect.

Therefore, when the power/communication cable connector is connected to the power/communication terminal 250, operation power can be supplied from the outside or detector ID information, a fire detection signal, and detection information of an external sensor can be transmitted to the outside.

The sensor extension terminal 260 is as shown in FIG. 4 so that the external sensor can be detachably coupled to the control board 210 for the extension installation of an external sensor that detects a fire in a method other than the smoke detection method. Similarly, as a kind of connecting terminal installed on the control board 210, when the sensor expansion control unit 200 is installed in the inner space of the sensor housing 100, as shown in FIG. 5, the first formed on the sensor housing 100 It is exposed to the outside through the two-terminal exposure hole 150 so that an external sensor can be detachably coupled.

The external sensor coupled to the sensor extension terminal 260 may be any one of a temperature detection sensor, a humidity detection sensor, and a flame detection sensor.

Depending on the characteristics of the fire detector installation site, various types of fire detectors are installed. Conventional fire detectors include a smoke detector that detects smoke to determine fire occurrence, a temperature detector that detects fire by detecting temperature, and a smoke detector that detects smoke and temperature. It is specialized and produced as a fuel temperature detector that detects the occurrence of fire and a flame detector that detects the occurrence of fire by detecting flame. There was a problem of incurring the cost of changing and installing all of them.

Therefore, even if the characteristics of the fire detector installation site are changed, there is no need to change and install the existing fire detector to a fire detector with a different detection characteristic, and the fire detection characteristics of the existing installed fire detector can be adjusted to the changed site characteristics while maintaining the existing installed fire detector. Sensor expandability is required so that it can be changed accordingly, and a configuration for this is the sensor extension terminal 260.

For example, if the characteristics of installation site A are changed to a situation in which a fire must be detected using smoke and flames while a fuel temperature detector that detects fire by detecting smoke and temperature is installed at fire detector installation site A, conventionally Inconvenience and additional costs were caused by removing the existing fuel temperature detector and installing new smoke detectors and flame detectors.

However, in the case of the present invention, in order to detect smoke and temperature, the temperature sensor, which is an external sensor previously coupled to the sensor extension terminal 260, is separated, and then the flame detection sensor is coupled to the sensor extension terminal 260. In this way, it is possible to change the detection characteristics of existing fire detectors (fire detection by detecting smoke and temperature) to the detection characteristics (fire detection by detecting smoke and flame) suitable for the new situation without the need to replace with a new fire detector. .

That is, the sensor extension terminal 260 allows the fire detector of the present invention to have detection sensor expandability, so that even if the characteristics of the installation site where the fire detector is installed are changed, the detection characteristics of the fire detector can be changed to suit the newly changed characteristics of the installation site. there will be

Hereinafter, specific functions of the control circuit 211 designed on the control board 210 will be described.

The control circuit 211 determines the power state, communication state, and fire detection state of the detector, and turns on a plurality of status indicators 220 to display the detected power state, communication state, and fire detection state of the detector, The detector ID information and grade information set through the detector ID setting unit 230 and the detector level setting unit 240 are stored and managed, and the received light amount information provided as smoke detection result information by the smoke detector 300 is the currently set detector level. If the light reception amount corresponding to is greater than or equal to, the detector ID information, the fire detection signal, and the detection information of the external sensor are transmitted to the outside, and the light reception amount information provided as the smoke detection result information by the smoke detector 300 corresponds to the currently set detector class. When the amount of received light is less than that, it is characterized in that sensor ID information and detection information of an external sensor are transmitted to the outside.

In particular, the detection information of the external sensor is temperature information when the external sensor coupled to the sensor extension terminal 260 is a temperature detection sensor, and the external sensor coupled to the sensor extension terminal 260 is a humidity detection sensor. , characterized in that the humidity information.

Specifically, the control circuit 211 determines the power state, communication state, and fire detection state of the detector, and displays a plurality of status indicators 220 to display the identified power state, communication state, and fire detection state of the detector. light up

That is, the control circuit 211 determines whether the power is normally supplied to the detector, and if the power is normally supplied, the power status indicator among the plurality of status indicators 220 is turned on (eg green), If the power is not normally turned on, do not turn on the power status indicator.

In addition, the detector determines whether or not communication with the outside is normally connected, and if the communication is normally connected, a communication failure state in which communication is not normally connected without turning on the communication status indicator among the plurality of status indicators 220. If not, turn on the communication status indicator (e.g. yellow).

In addition, when it is determined that a fire has occurred using the received light amount information provided by the smoke detection unit 300 as the smoke detection result information and the detection information of the external sensor, the fire status indicator light among the plurality of status indicator lamps 220 is turned on (eg : red), and if it is judged that there is no fire, the fire status indicator is not turned on.

In particular, when the control circuit 211 determines that a fire has occurred in a state in which the communication state is poor, the communication state indicator lamp and the fire state indicator light are repeatedly turned on, so that the fire detection signal is generated due to the communication failure despite the occurrence of a fire. An emergency situation that is not being transmitted to the outside informs the surroundings of a lighting alarm.

That is, when the fire detector detects that a fire has occurred, it must transmit a fire detection signal to the outside. Despite the fire, if the fire detection signal is not transmitted to the outside due to poor communication, the external In this case, the control circuit 211 repeatedly turns on the communication status indicator light and the fire status indicator light, so that the fire detection signal is not being transmitted to the outside due to poor communication despite the occurrence of a fire. The emergency situation is notified to the surroundings through repeated lighting alarms of the communication status indicator and fire status indicator.

In addition, the control circuit 211 stores and manages sensor ID information and level information set through the sensor ID setting unit 230 and the sensor level setting unit 240 .

As described above, the user sets the sensor ID and the sensor level through the sensor ID setting unit 230 and the sensor level setting unit 240. When the user sets the sensor ID and level, the control circuit 211 Stores and manages set detector ID information and grade information.

For example, when the user sets the sensor ID to #01 through the sensor ID setting unit 230 and the sensor level to 1 type through the sensor level setting unit 240, the control circuit 211 controls the set sensor ID information. and to store and manage grade information.

If the detector grade is set to 1 type, when the smoke detection unit 300 generates a fire detection signal using the received light amount information provided as smoke detection result information, a fire detection signal is generated when smoke is detected by 5%, If the detector level is set to 2, a fire detection signal is generated when 15% of smoke is detected.

In addition, the control circuit 211 controls the detector ID information, the fire detection signal, and the detection information of the external sensor when the light reception amount information provided by the smoke detection unit 300 as the smoke detection result information is greater than or equal to the light reception amount corresponding to the currently set detector class. is transmitted to the outside, and when the light received amount information provided as the smoke detection result information by the smoke detector 300 is less than the light received amount corresponding to the currently set detector class, the sensor ID information and the detection information of the external sensor are transmitted to the outside.

The smoke detector 300, which will be described later, detects smoke by a scattered light detection method, and provides light-received amount information to the control circuit 211 as smoke detection result information.

Therefore, the control circuit 211 determines that a fire has occurred if the received light amount according to the received light amount information provided by the smoke detection unit 300 as the smoke detection result information is greater than or equal to the light received amount corresponding to the currently set sensor class.

The control circuit 211 stores sensor class information set by the user and information matching the sensor class and received light amount, so that the light received amount by the light received amount information provided by the smoke detector 300 corresponds to the currently set sensor class. If it is above, it is determined that a fire has occurred, and if it is less than the received light amount corresponding to the currently set sensor level, it is determined that there is no fire.

For example, if the currently set detector class is set to type 1 and the light received amount according to the light received amount information provided by the smoke detector 300 is greater than the light received amount corresponding to the first type (the light received amount when 5% smoke is detected) It is determined that a fire has occurred, and if the light reception amount corresponding to the first type (the light reception amount when 5% smoke is detected) is less than that, it is determined that no fire has occurred.

In addition, if the currently set detector class is set to 2 types and the light reception amount according to the light reception amount information provided by the smoke detector 300 is greater than the light reception amount corresponding to 2 types (the light reception amount when 15% smoke is detected), a fire may occur. It is determined that a fire has occurred, and if the light reception amount corresponding to the second type (the light reception amount when 15% smoke is detected) is less than that, it is determined that no fire has occurred.

The control circuit 211 transmits the detector ID information, the fire detection signal, and the detection information of the external sensor to the outside when it is determined that a fire has occurred, and the detector ID information and the detection information of the external sensor when it is determined that there is no fire transmits to the outside.

The detection information of the external sensor transmitted to the outside by the control circuit 211 is temperature information when the external sensor coupled to the sensor extension terminal 260 is a temperature sensor, and is coupled to the sensor extension terminal 260. When the external sensor is a humidity sensor, it is characterized in that it is humidity information.

That is, when it is determined that there is no fire, the sensor ID information and the detection information (temperature or humidity information) of the external sensor are transmitted to the outside so that the manager can monitor the temperature or humidity of the place where the fire detector is installed. and if it is determined that a fire has occurred, the detector ID information, fire detection signal, and detection information (temperature or humidity information) of the external sensor are transmitted to the outside so that the manager can monitor the temperature or humidity of the place where the fire detector is installed. and at the same time make them aware that a fire has occurred.

On the other hand, the control circuit 211 basically determines the occurrence of a fire using the information on the amount of light received provided by the smoke detector 300, but also by using the detection information provided by an external sensor coupled to the sensor extension terminal 260. Determine whether a fire has occurred.

That is, the control circuit 211 complexly determines whether or not a fire has occurred by using the light reception amount information provided by the smoke detection unit 300 and the detection information provided by the external sensor, and the light reception amount information provided by the smoke detection unit 300 If at least one of the detected information provided by the external sensor is information indicating the occurrence of a fire, it is determined that a fire has occurred.

Specifically, when the external sensor coupled to the sensor extension terminal 260 is a temperature sensor, the control circuit 211 controls the temperature information provided by the temperature sensor, which is an external sensor, to a preset temperature (e.g., 80° C.) or higher, it is determined that a fire has occurred regardless of the received light amount information provided by the smoke sensor 300, and sensor ID information, a fire detection signal, and temperature information, which is detection information of an external sensor, are transmitted to the outside.

In addition, when the external sensor coupled to the sensor extension terminal 260 is a flame detection sensor, the control circuit 211 provides the smoke detection unit 300 when the flame detection sensor, which is an external sensor, provides flame detection information. Regardless of the received light amount information, it is determined that a fire has occurred and the detector ID information and fire detection signal are transmitted to the outside.

The smoke detection unit 300 is installed inside the detector housing 100, detects smoke in a scattered light method, and provides smoke detection result information to the sensor extension control unit 200, as shown in FIG. , Attached to the control board 210 of the sensor extension control unit 200.

Specifically, the smoke detector 300, as shown in FIG. 6,

In a non-occurring state (a state in which smoke is not introduced into the smoke sensing chamber 310), as shown in FIG. 7A, the light emitted from the light emitting element 320 is not received by the light blocking wall 350. And, in a fire state (a state in which smoke is introduced into the smoke sensing chamber 310), light scattered by the introduced smoke is received, as shown in B of FIG. 7 .

Therefore, when light is received, the light receiving sensor 330 provides the received light amount, which is the amount of light received, to the control circuit 211 of the sensor extension control unit 200 as smoke detection result information.

The mesh filter 340 is configured to be installed around the side of the smoke sensing chamber 310 so that foreign substances other than smoke are not introduced through the smoke inflow passage formed on the side of the smoke sensing chamber 310 .

Foreign substances other than smoke may flow into the smoke detection chamber 310 in a state where no fire occurs, and when light is scattered by the introduced foreign substances, the light receiving sensor 330 transmits light received amount information to the control circuit 211 It can be misunderstood that a fire has occurred by providing a mesh filter 340 on the side of the smoke detection chamber 310 to prevent this.

The light blocking wall 350 blocks light generated from the light emitting element 320 from being directly directed to the light receiving sensor 330 .

In a state in which a fire does not occur, the light emitted from the light emitting element 320 should not be received by the light receiving sensor 330. 330) provides information on the amount of light reception to the control circuit 211 so that it may be misunderstood as a fire.
