Alarm device based on electromagnetic wave emission base

Abstract

The invention discloses an alarm device based on an electromagnetic wave emission base. Comprising a first shell, a sealing assembly, a module fixing assembly, a self-cleaning assembly, a support, a double-shaft motor, fan blades, a first gear, a second connecting rod, a filter element, a second gear, a first connecting shaft, a first supporting block, a third gear, a fourth gear, a second connecting shaft, a second supporting block, a fifth gear, a sixth gear, a third connecting shaft and a cleaning rod. According to the invention, the module fixing assembly is designed and can be used for separately installing each circuit module, so that mutual interference among the modules is reduced, and later maintenance and element replacement are facilitated; the self-cleaning assembly is designed, the filter element can be automatically cleaned, manual maintenance is not needed, and the assembly and the heat dissipation device use the same power source, so that the element cost is reduced, and meanwhile, the size of the device is prevented from being increased; a sealing assembly is designed, and the sealing assembly is convenient to use and can be used for rapid disassembly and assembly of the device.

Description

technical field [0001] The invention relates to the technical field of alarm devices, in particular to an alarm device based on an electromagnetic wave emission base. Background technique [0002] Electromagnetic wave is a kind of transverse wave, which can be used for detection, positioning and communication. A device that detects a human body moving within the range and generates an alarm signal to realize area monitoring. The microwave detector is usually equipped with a microwave generation module, a main control module, a power supply module and a controller module. However, each module is welded The electromagnetic interference generated by the power supply module and the controller module will affect the normal operation of the microwave generation module and bring great inconvenience to the later maintenance and replacement of components; the existing microwave detector is designed with a heat dissipation function , so as to avoid the change of the resistance value ...

[0002] Electromagnetic wave is a kind of transverse wave, which can be used for detection, positioning and communication. A device that detects a human body moving within the range and generates an alarm signal to realize area monitoring. The microwave detector is usually equipped with a microwave generation module, a main control module, a power supply module and a controller module. However, each module is welded The electromagnetic interference generated by the power supply module and the controller module will affect the normal operation of the microwave generation module and bring great inconvenience to the later maintenance and replacement of components; the existing microwave detector is designed with a heat dissipation function , so as to avoid the change of the resistance value caused by the high temperature, but the filter screen that acts as a dust filter needs to be manually dismantled and washed, resulting in inconvenient maintenance; the existing microwave detector uses screws to fix the seal of the shell, although this method is stable , but the disassembly and assembly of the screws needs to be assisted by tools, and the screws have the risk of slipping, which will cause inconvenient disassembly and assembly
