Description

Technical Field

[0001] This utility model relates to the technical field of combustible gas alarms, specifically to a quick-install combustible gas alarm. Background Technology

[0002] Commonly used combustible gases include coal gas and natural gas. While these gases provide many conveniences and create much value for people's lives and production, leaks can cause poisoning, fires, and explosions. The consequences of such accidents are unimaginable, seriously threatening people's lives and property. A gas detector, also known as a combustible gas detector, is a detector that responds to the concentration of one or more combustible gases. Household combustible gas alarms are typically installed on the kitchen wall to detect natural gas.

[0003] Chinese Patent CN219530493U discloses a household quick-install combustible gas alarm, including a combustible gas alarm body. A mounting base is fixedly connected to one side of the body, and a rubber suction cup is provided on one side of the mounting base. An air intake pipe is located inside the mounting base, extending into the rubber suction cup. A movable block is slidably connected inside the air intake pipe, and a threaded rod is threadedly connected to the bottom of the movable block. This invention first uses double-sided adhesive to fix the mounting ring to the kitchen tile wall for initial fixation. Then, rotating the knob causes the air intake pipe to draw air out of the rubber suction cup, completing the fixation. The fixation method is simple. Simultaneously, rotating the knob in the opposite direction inflates the rubber suction cup, allowing the combustible gas alarm body to be easily removed from the mounting ring for maintenance. The double fixation of the double-sided adhesive and the rubber suction cup enhances the stability of the installation.

[0004] However, the above technical solution has the following shortcomings: it relies on rotating the threaded rod to drive the moving block to extract the air inside the rubber suction cup, thereby generating negative pressure. In actual operation, continuous rotation of the vortex is required to drive the moving block to move a sufficient distance, which is very inconvenient to operate and has poor practicality.
