This invention discloses a conveniently adjustable one-way valve, comprising a valve body and a fixed rod. The inner wall of the valve body is fixedly connected to the fixed rod, and a sliding plate is slidably connected to the outer surface of the fixed rod. A fixed plate is fixedly connected to the inner side wall of the sliding plate, and an installation rod is fixedly connected to one side of the fixed plate. An installation plate is fixedly connected to one side of the installation rod, and a valve ball is fixedly connected to one side of the installation plate. An inlet pipe is fixedly connected to the inner side wall of the valve body. This conveniently adjustable one-way valve allows for easy adjustment during use. By pulling the lever to one side, a movable plate is moved, simultaneously causing a locking block to be removed from its slot. The hexagonal locking block is then removed, matched with the hexagonal prism, and adjusted. After adjustment, the hexagonal locking block is installed into the hexagonal mounting bracket. The elasticity of a second spring then causes the movable plate and the locking block to engage and fix in the slot, thus facilitating adjustment and achieving the desired adjustment.

The utility model discloses an air conditioner external cleaning device for air conditioner refrigeration equipment, which belongs to the field of cleaning devices and comprises an anti-skidding handle and an arranged adjusting mechanism. According to the air conditioner cleaning device, the use height of the cleaning mechanism can be adjusted, air conditioners installed at different high positions can be cleaned conveniently, then, when a user holds the whole device through an anti-skid handle and moves a cleaning plate, the two sides of the exterior of the air conditioner can be cleaned through cleaning brushes on the side wall of the cleaning plate, and the cleaning efficiency is improved. After the cleaning plate is turned over to enable the cleaning brush to face downwards, a user can move the whole device to clean the external top surface of the air conditioner, and after the cleaning plate is turned over to enable the cleaning brush to face upwards, the user can move the whole device to clean the external bottom surface of the air conditioner; the cleaning plate is kept in a vertical state and moved, and the front outside the air conditioner can be cleaned through the cleaning brush.
