[0002] Natural gas, as a green, environmentally friendly, economical and reliable gaseous fuel, is widely used in all walks of life. Especially household gas greatly improves the home environment and the quality of life. In the process of using household natural gas, in order to ensure the use safety and avoid natural gas leakage, a gas alarm device is needed to detect natural gas in the air and give an alarm in time when natural gas leakage occurs to avoid danger. With the progress of technology, an energy-saving gas alarm based on the Internet of Things is put into use, that is, it is connected to the user's mobile terminal or computer through a wireless network to detect danger in time.

[0003] Deficiencies of the prior art: Most household gas alarms are installed in the kitchen. However, the kitchen environment is complex during use and there is a lot of lampblack. In order to prevent lampblack from entering the equipment during use, a filter screen is usually provided at the air inlet of the equipment. However, as time goes by, sundries adhere to the filter screen, causing blockage and requiring disassembly and cleaning. The filter screens of existing household gas alarms are mostly fixed by bolts, which is time-consuming and laborious during disassembly; at the same time, existing household gas alarms are fixed on the kitchen wall, which is not convenient to take and detect different positions. Summary of the Invention

When the mounting mechanism 3 is fixed at a suitable position and the device is placed, the alarm main body 201 is placed inside the mounting seat 301. The fixing pin 203 contacts the limiting block 302, so that the fixing pin 203 is received inside the second mounting hole 208 until the limiting block 302 moves above the fixing pin 203. Then, the first return spring 207 pushes the fixing pin 203 so that the fixing pin 203 is stuck at the bottom end of the limiting block 302, realizing the fixation of the alarm mechanism 2. When the alarm mechanism 2 needs to be taken out, the alarm main body 201 is continuously moved downward, so that the fixing pin 203 contacts the movable block 307 and the fixing pin 203 is received inside the second mounting hole 208. Then, the fixing pin 203 contacts the bottom of the movable block 307 and the alarm main body 201 is pulled upward, so that the fixing pin 203 pulls the movable block 307 to move upward, so that the top end of the movable block 307 is received at the bottom of the limiting block 302.
