Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1-5, a flusher comprises a water pipe 1 connected to the top of a urinal 7, wherein an electromagnetic valve 2 is installed on the water pipe 1, a control box 3 is arranged above the water pipe 1, a panel 4 is installed on the control box 3, an infrared sensor 5 pointing to the right front is installed on the panel 4, and the electromagnetic valve 2 is connected into the control box 3 through a pipeline 6 electric signal;

The control box 3 is internally provided with a control main board, the control main board takes a 32-bit singlechip 12 as a control core, a timer 13 and a power supply module 14 are integrated, the electromagnetic valve 2 and the infrared sensor 5 are electrically connected with the singlechip 12, infrared sensing can be divided into shielding type and reflection type, and the reflection type pyroelectric infrared sensor is adopted as a switch in the embodiment.

After the urinal 7 is installed according to the existing method, the water pipe 1 is connected to the urinal 7, then the control box 3 is powered on, when a person approaches to the urinal and is sensed by the infrared sensor 5, the timer 13 starts to count time, the timer is started to stop sensing disconnection, when the count time length is less than or equal to 3S threshold (settable), the singlechip 12 does not send an opening instruction to the electromagnetic valve 2, when the person only passes the sensor by the infrared sensor 5, the water pipe 1 cannot trigger the switch to flush, so that water resource waste caused by false sensing can be avoided, when the count time length is greater than 3S threshold (settable), the singlechip 12 sends an opening instruction to the electromagnetic valve 2, the electromagnetic valve 2 is electrified to open once, and water in the water pipe 1 flows into the urinal 7 to be flushed.

In the embodiment, a connecting pipe 8 is mounted on a water pipe 1 in front of an electromagnetic valve 2 through bolts, a screen 15 is mounted in pipe orifices at two ends of the connecting pipe 8, a sleeve 9 communicated with the inside is welded on the connecting pipe 8, a screw cap 11 is connected to the sleeve 9 through threads, the sleeve 9 is an external thread, and the screw cap 11 is an internal thread.

The connection pipe 8 can be internally provided with odor removing products such as aromatic balls or camphor balls, the rotary cap 11 is opened, the aromatic balls or camphor balls are put into the connection pipe 8 from the inside of the sleeve 9, when the electromagnetic valve 2 is opened for flushing, water flows through the connection pipe 8 and contacts with the aromatic balls or camphor balls, so that part of the aromatic balls or camphor balls are dissolved into the water flow, when the water flow flushes the urinal 7, the odor removing effect can be additionally provided outside the flushing, the existing aromatic balls or camphor balls are generally directly put into the urinal, and when the water flow flushes, the urinal flows out and contacts with the aromatic balls or camphor balls, and odor removal cannot be carried out when the water flow flushes.
