Description

Technical Field

[0001] The invention relates to the field of smoke alarms, and in particular to a smoke alarm for a tea processing workshop. Background Art

[0002] In industrial production plants and various workshop environments, smoke alarms play a vital role in safety monitoring. However, existing smoke alarms have many usage pain points and are difficult to meet high-intensity monitoring needs. On the one hand, traditional smoke alarms are easily interfered by environmental factors. For example, in the factory area, the floating of small amounts of dust and the escape of smoke generated by tea frying and other work often cause false alarms of smoke alarms. Once a false alarm occurs, it will not only disrupt the normal production order, but also require manual reset operations, wasting manpower and time costs. On the other hand, traditional smoke alarms lack effective self-cleaning and verification mechanisms, and it is easy for too much smoke to remain inside the sensing chamber, which will not only cause subsequent false alarms for a long time, but also affect the detection accuracy of the alarm. In addition, in order to maintain its normal operation, manual cleaning is required regularly, which increases the complexity and workload of maintenance in such high-intensity monitoring scenarios as factory workshops. In addition, during the installation of the smoke alarm, due to the lack of protective measures, the fine dust generated during the installation is easy to enter the alarm, affecting the subsequent actual monitoring effect.

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] like Figure 1-Figure 7 The smoke alarm for tea processing workshop shown in the figure includes a smoke detector 1, which includes a lower shell 101, an upper shell 103 is installed on the top of the lower shell 101, and a mounting seat 105 is fixedly connected to the top of the upper shell 103. A battery compartment 116 is arranged on one side of the lower shell 101, and a battery 110 is arranged inside the battery compartment 116. A circuit board 118 is arranged on one side of the battery compartment 116, and a sensing compartment 117 is installed on the upper part of the circuit board 118. A light source is provided, a photoelectric sensor is installed in the middle of the bottom end of the induction compartment 117, the light source and the photoelectric sensor are electrically connected to the circuit board 118, the circuit board 118 is electrically connected to the battery compartment 116, and evenly distributed vents 123 are provided on both sides of the middle of the induction compartment 117, a reset button 102 is provided on one side of the middle of the bottom end of the lower shell 101, an indicator light 111 is provided on one side of the reset button 102, and the indicator light 111 and the reset button 102 are electrically connected to the circuit board 118 and the battery 110;

[0027] Furthermore, in specific implementation, people can monitor the smoke inside the tea processing workshop through the smoke detector 1. There is a light emitting diode LED as a light source inside the alarm, and a photoelectric sensor, which are placed at a 90-degree angle. Under normal circumstances, the light emitted by the LED lamp propagates in a straight line and will not shine on the photoelectric sensor. When smoke follows the airflow through the air intake grille 104 and enters the smoke detector 1, the smoke particles will scatter the light, and part of the scattered light will shine on the photoelectric sensor. After receiving the light signal, the photoelectric sensor will convert it into an electrical signal. When the intensity of the electrical signal reaches a certain threshold, it will trigger the alarm to sound an alarm, thereby realizing the fire and smoke monitoring work in the tea processing workshop.

[0028] Among them, an exhaust hood 122 is arranged on the top of the induction bin 117, a small fan is installed in the upper part of the exhaust hood 122, a plurality of ventilation pipes 124 are installed on the outer periphery of the exhaust hood 122, and the ends of the ventilation pipes 124 away from the exhaust hood 122 are fixedly connected with a semi-ring hood 125, which is installed in the middle of the outer periphery of the exhaust hood 122, and the middle part of the inner side of the exhaust hood 122 is provided with evenly distributed through holes, and a top spring 130 is arranged on the inner side of the bottom of the exhaust hood 122, and the top spring 130 is arranged between the exhaust hood 122 and the induction bin 117, a fixing frame 119 is installed on the top of the circuit board 118, an electric push rod 121 is installed in the middle of the top of the fixing frame 119, and the bottom of the electric push rod 121 is arranged on the upper part of the exhaust hood 122;

[0029] Furthermore, in specific implementation, when smoke or dust floats into the smoke alarm 1, the photoelectric sensor inside the sensing chamber 117 will be triggered. When the alarm is triggered, the photoelectric sensor will synchronously start the impeller 113 and the electric motor 107. The operation of the electric motor 107 can drive the reciprocating threaded rod 129 to rotate, and the reciprocating threaded rod 129 drives the sealing ring 120 to move up and down when rotating. In this process, the operation of the impeller 113 will generate suction inside the vacuum chamber 114, and the suction pipe 126 and the connecting pipe 128 can transmit the suction force to the inside of the spiral ring tube 106. The suction hole 109 on the spiral ring tube 106 can realize the extraction of surrounding air. The electric motor 107 will complete a work process each time it works, that is, first down and then up. After completing a work process, the sealing ring 120 will reset and not move. Through this work process, when the smoke alarm is triggered by the smoke alarm 1, verification work can be performed to remove small streams of smoke and dust around.

[0030] Among them, an evenly distributed air intake grille 104 is opened at the lower part of the outer periphery of the upper shell 103, a sealing ring 120 is slidably connected to the upper part of the outer periphery of the upper shell 103, a spiral ring tube 106 is arranged at the lower part of the outer periphery of the sealing ring 120, and evenly distributed air intake holes 109 are opened at the outer periphery of the spiral ring tube 106, and the air intake holes 109 are connected to the inside of the sealing ring 120, and a connecting pipe 128 is penetrated at the top of the sealing ring 120, and a bottom ring 127 is fixedly connected to the bottom of the connecting pipe 128, and the bottom ring 127 is slidably connected to the outer periphery of the upper shell 103, and the connecting pipe 128 is connected to the inside of the sealing ring 120, and an exhaust pipe 126 is fixedly connected to one side of the top of the connecting pipe 128, and the side of the exhaust pipe 126 away from the connecting pipe 128 penetrates the wall of the upper shell 103, and the end of the exhaust pipe 126 away from the connecting pipe 128 penetrates the lower part of the outer periphery of the exhaust bin 114;

[0031] Furthermore, in the specific implementation, the small fan inside the exhaust hood 122 will start working, and the smoke and dust inside the sensing chamber 117 will be extracted through the ventilation pipe 124 and the semi-ring cover 125. When the sealing ring 120 is reset, the electric push rod 121 is reset synchronously, and the top spring 130 drives the exhaust hood 122 to rise. At this time, the photoelectric sensor inside the sensing chamber 117 can resume detection again. If no smoke is detected at this time, it is caused by the escape of small amounts of smoke and dust. At this time, the circuit board 118 will turn off the alarm. If the photoelectric sensor still detects smoke, the alarm will continue. The automatic verification work after the alarm can realize the self-inspection of the smoke detector 1, and avoid the smoke detector 1 from generating false alarms due to the escape of small amounts of floating dust or smoke from tea frying work. This is beneficial to the actual use of the factory and avoids the need for manual reset after a false alarm.

[0032] Among them, an air pumping bin 114 is arranged in the middle of the bottom end of the mounting seat 105, an impeller 113 is installed inside the air pumping bin 114, a breathable back plate 112 is installed on the top of the air pumping bin 114, and evenly distributed air guide grooves 115 are opened on the top edge of the mounting seat 105. Electric motors 107 are installed on both sides of the upper part of the outer periphery of the upper shell 103, and the bottom driving end of the electric motor 107 is fixedly connected with a reciprocating threaded rod 129, and the bottom of the reciprocating threaded rod 129 passes through the top of the sealing ring 120, and the reciprocating threaded rod 129 is threadedly connected with the sealing ring 120. The electric motors 107 are installed in the middle of the mounting ring 108, and the mounting ring 108 is fixedly connected to the outer side of the bottom end of the mounting seat 105, and the mounting ring 108 is arranged on the upper part of the outer periphery of the upper shell 103;

[0033] Furthermore, in specific implementation, during the verification process, the smoke and dust remaining in the sensing bin 117 can be sucked out through the operation of the small fan inside the exhaust hood 122, so as to avoid excessive smoke and dust remaining inside the sensing bin 117, which may cause false alarms for a long time in the future. At the same time, the accuracy of the verification work after the alarm can be guaranteed, and the cleaning work inside the sensing bin 117 can be realized, thereby reducing the pain point of traditional smoke alarms that require regular cleaning, which is conducive to coping with high-intensity monitoring work in factory workshops. In actual use, at the initial stage of installation of the smoke detector 1, people can manually start the smoke detector 1, thereby starting the electric motor 107, and the operation of the electric motor 107 drives the sealing ring 120 to descend, thereby shielding the air intake grille 104, so as to avoid the fine dust generated during the installation process from entering the smoke detector 1 and affecting the subsequent actual monitoring process.

[0034] Working principle:

[0035] In actual use, people can monitor the smoke inside the tea processing workshop through the smoke alarm 1. There is a light emitting diode LED as a light source inside the alarm, and a photoelectric sensor, which are placed at a 90-degree angle. Under normal circumstances, the light emitted by the LED lamp propagates in a straight line and will not shine on the photoelectric sensor. When smoke follows the airflow through the air intake grille 104 and enters the smoke alarm 1, the smoke particles will scatter the light, and part of the scattered light will shine on the photoelectric sensor. After receiving the light signal, the photoelectric sensor will convert it into an electrical signal. When the intensity of the electrical signal reaches a certain threshold, it will trigger the alarm to sound an alarm, thereby realizing the fire smoke monitoring work in the tea processing workshop. During actual use, when smoke or dust floats into the smoke alarm 1, the photoelectric sensor inside the sensing bin 117 will be triggered. When the photoelectric sensor triggers the alarm, the impeller 113, the electric push rod 121 and the electric motor 107 will be synchronously started. When the electric push rod 121 is working, the exhaust hood 122 will be pressed down to cover the sensing bin 117. At this time, the smoke and dust retained in the sensing bin 117 can be sucked out by the operation of the small fan inside the exhaust hood 122. The operation of the electric motor 107 can drive the reciprocating threaded rod 129 to rotate. When the reciprocating threaded rod 129 rotates, it drives the sealing ring 120 up and down. In this process, the operation of the impeller 113 will generate suction inside the exhaust bin 114, and the exhaust pipe 126 and the connecting pipe 12 8 can transmit the suction force to the inside of the spiral ring tube 106, and the surrounding air can be extracted through the suction hole 109 on the spiral ring tube 106. The electric motor 107 will complete a work process each time it works, that is, first down and then up. After completing a work process, the sealing ring 120 will be reset and not move. Through this work process, when the smoke alarm 1 triggers the smoke alarm, the verification work can be carried out to suck out the small smoke and dust around. At the same time, the small fan inside the exhaust hood 122 will start to work, and the smoke and dust inside the sensing bin 117 will be extracted through the ventilation pipe 124 and the semi-ring cover 125. When the sealing ring 120 is reset, the electric push rod 121 is reset synchronously, and the top spring 130 drives the exhaust hood 122 to rise. At this time, the photoelectric inside the sensing bin 117 The sensor can resume detection again. If no smoke is detected at this time, it is caused by the escape of small amounts of smoke and dust. At this time, the circuit board 118 will turn off the alarm. If the photoelectric sensor still detects smoke, the alarm will continue. The automatic verification work after the alarm can realize the self-inspection of the smoke detector 1, and avoid the escape of small amounts of floating dust or smoke from tea frying work, which may cause the smoke detector 1 to produce false alarms. This is beneficial to the actual use of the factory and avoids the need for manual reset after a false alarm. At the same time, during the verification process, the smoke and dust retained in the sensing bin 117 can be sucked out through the work of the small fan inside the exhaust hood 122, so as to avoid excessive smoke and dust inside the sensing bin 117, which may cause false alarms for a long time in the future. At the same time, the accuracy of the verification work after the alarm can be guaranteed.And it can realize the cleaning work inside the sensing chamber 117, reducing the pain point of using traditional smoke alarms that need regular cleaning, which is conducive to coping with the high-intensity monitoring work in the factory workshop. In actual use, at the initial stage of installing the smoke alarm 1, people can manually start the smoke alarm 1, thereby starting the electric motor 107, and the sealing ring 120 is driven down by the work of the electric motor 107, so as to cover the air intake grille 104, so as to avoid the fine dust generated during the installation process from entering the smoke alarm 1 and affecting the subsequent actual monitoring process.
