Description

Technical Field

[0001] The utility model relates to the technical field of flame detection, in particular to a flame detector. Background Art

[0002] A flame detector is a safety device used to detect flames. Traditional flame detectors only have a switching output with a single output format. External devices cannot read the status information of the device in a timely manner. In addition, traditional flame detectors need to be connected to an alarm when in use. When the detector detects a flame, the alarm cannot be triggered in time.

[0003] For this purpose, we design a flame detector here. Utility Model Content

[0004] The purpose of the present invention is to provide a flame detector to address the deficiencies of the prior art and to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a flame detector, comprising a shell, which is a cylindrical tube with a sealed rear end, a circular mainboard installed at the front port of the shell, a flame photoelectric tube installed at the center of the front of the mainboard, nine LED lights distributed in a circular array with the center of the mainboard installed near the edge of the front of the mainboard, and a buzzer, an RS485 chip interface, a relay switch output, and a LORA wireless transmission module also installed on the front of the mainboard.

[0006] Preferably, the flame detector further comprises a threaded sheath, a protective glass is installed on the inner side of the threaded sheath, and the threaded sheath is connected to the front port of the housing through threads.

[0007] Preferably, a sun visor is installed on the top of the shell, and the front end of the sun visor extends beyond the front end of the shell by about 3cm-5cm.

[0008] Preferably, an adjustment bracket is installed at the rear end of the housing.

[0009] Compared with the prior art, the present invention provides a flame detector with the following features:

[0010] Beneficial effects:

[0011] Compared to traditional flame detectors, this flame detector features an RS485 chip interface. External devices can access this interface to instantly read device information (e.g., determine if a fire alarm is active). Fire detection sensitivity can also be adjusted via the RS485 chip interface. Furthermore, it features an LED light and buzzer, controlled by the main control board to provide timely alerts. Compared to traditional flame detectors, this device is more sensitive and can trigger alarms promptly. The mainboard's LoRa module enables long-distance wireless signal transmission. Relays output switching signals in a timely and efficient manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 and Figure 2In this embodiment: a flame detector includes a shell 1, which is a cylindrical tube with a sealed rear end. A circular main board 2 is installed at the front end of the shell 1, and a flame photoelectric tube 7 is installed at the center of the front of the main board 2. Nine LED lights 8 are installed on the front of the main board 2 near the edge, distributed in a circular array with the center of the main board 2. A buzzer 9, an RS485 chip interface 10 and a relay switch output 11 are also installed on the front of the main board 2. The flame photoelectric tube 7 can detect ultraviolet light in the flame and is completely insensitive to visible light, which can effectively prevent interference from sunlight. Therefore, the flame photoelectric tube 7 can play a role in highly sensitive flame detection. A main control board is provided in the shell 1 to control the operation of the LED light 8 and the buzzer 9. The function of the LED light 8 is to emit a light alarm when the flame photoelectric tube 7 detects a flame. The function of the buzzer 9 is to emit a sound alarm when the flame photoelectric tube 7 detects a flame. The function of the RS485 chip interface 10 is to allow external devices to read the device information in a timely manner.

[0017] The flame detector can be set to two output modes. One is that when the flame phototube 7 detects a flame, the LED light 8 flashes red, and the buzzer 9 sounds an alarm. After the flame disappears, the LED light 8 and the buzzer 9 are automatically turned off. The other is that when the flame phototube 7 detects a flame, the LDE light 8 flashes red, and the buzzer 9 sounds an alarm. After the flame disappears, the LED light 8 and the buzzer 9 will not be automatically turned off, and the user needs to manually power off the power. The specific output mode to be used is selected according to actual conditions. The flame detector can also be equipped with a wireless LORA module in the shell 1 so that the detector signal can be sent wirelessly.

[0018] The flame detector also includes a threaded sleeve 3, a protective glass 4 is installed on the inner side of the threaded sleeve 3, and the threaded sleeve 3 is connected to the front port of the shell 1 by a thread. The function of the protective glass 4 is to protect the components installed on the main board 2 while not hindering the flame photoelectric tube 7 from detecting ultraviolet rays in the flame. A sun visor 5 is installed on the top of the shell 1, and the front end of the sun visor 5 extends beyond the front end of the shell 1 by approximately 3cm-5cm. An adjustment bracket 6 is installed at the rear end of the shell 1. The detection direction of the flame photoelectric tube 7 can be adjusted by adjusting the bracket 6. The adjustment bracket 6 can be fixed to a wall or a column by bolts.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
