Automatic flush sensing assembly

An automatic flush sensing assembly comprising:

• a driving device having a power supply and a motor electrically connected together and disposed in a housing, the housing having a through hole, a switch connected to the motor extending through the through hole, the switch provided with a rotable arm outside of the housing, and the housing further provided with a cover and an assembling aperture;
• a handle having an inner space, a rod disposed at an end of the inner space, the handle having a through aperture disposed at an upper surface and connected to the inner space;
• the inner space figured to be covered by a bottom board, the bottom board having a first assembling aperture corresponding to the rod;
• the bottom board provided with a sensor in the inner space, and the sensor having a sensing member facing the through aperture of the handle and connected to a signal cable;
• and
• a securing member having a front sleeve, a linkage member and a rear sleeve;
• the front sleeve having a second assembling aperture jacketed onto the rod, an end of the front sleeve distal from the handle provided with an outer thread, a linear slot disposed adjacent to the outer thread such that the signal cable of the sensor passes through the first assembling aperture, the second assembling aperture and the linear slot;
• the outer thread of the front sleeve inserted into the assembling aperture of the housing, the signal cable connected to the motor and the power supply;
• the rear sleeve provided with a containment hole limiting the linkage member, the containment hole provided with an inner thread, another end of the rear sleeve inserted into the assembling aperture of the housing;
• the front sleeve and the rear sleeve locked with each other via an engagement between the inner and outer threads, an end of the linkage member connected to the rod of the handle, another end of the linkage member passing through the rear sleeve and provided with an enlarged portion, the enlarged portion secured to a control strip, the control strip disposed across and above the arm of the switch;
• wherein when the sensor of the handle is activated, the motor drives the switch to rotate the arm to push the control strip.
