Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

As shown in fig. 4, a flushing sensor for public toilets includes a housing 2, a mounting bracket 24, and a sensing probe 3.

As shown in fig. 1 to 3, the back of the housing 2 is disposed on the wall of the toilet 1, the bottom end of the front of the housing 2 is provided with an inward concave inclined surface 213, the front center of the housing 2 and the center of the inclined surface 213 respectively penetrate through a first sensing window 211 and a second sensing window 212, the arrangement of the first sensing window 211 and the second sensing window 212 is beneficial to the sensing of the sensing probe 3, and the arrangement of the inclined surface 213 can make the sensing angles of the sensing probe 3 disposed on the first sensing window 211 and the second sensing window 212 different, so that the sensing area of the sensor is enlarged, and the sensitivity of the sensor is improved.

As shown in fig. 4 and 5, the two mounting frames 24 are provided, the two mounting frames 24 are all disposed in the housing 2, the mounting frames 24 are respectively covered on a first sensing window 211 and a second sensing window 212, the sensing probe 3 comprises a first probe 32 and a second probe 33, the first probe 32 and the second probe 33 are respectively disposed on the mounting frames 24 at the first sensing window 211 and the second sensing window 212, the first probe 32 and the second probe 33 are used for sensing the approach of a human body, and the first probe 32 and the second probe 33 are used for controlling the start and stop of the flushing of the toilet 1. The first probe 32 and the second probe 33 are both infrared probes, the first probe 32 and the second probe 33 emit infrared induction lines when in use, an induction area is formed, and after a person enters or leaves the induction area, the first probe 32 or the second probe 33 can emit induction signals to a flushing system of the toilet 1, so that a flushing valve in the flushing system is opened. Specifically, when a human body enters the sensing area of the first probe 32, the first probe 32 sends out a sensing signal, the signal is transmitted to the flushing system of the toilet bowl 1, a flushing valve in the flushing system is opened to flush water before the toilet bowl is used, then a user walks away if standing the toilet bowl 1, and after the user is used, the first probe 32 sends out the sensing signal again after leaving the sensing area of the first probe 32, the signal is transmitted to the flushing system of the toilet bowl 1, the flushing valve is opened to flush water after the toilet bowl is used.

As shown in fig. 1, when a person uses the toilet 1 in a squatting condition after flushing before sitting, the person enters the sensing area of the first probe 33, and simultaneously gets away from the sensing area of the second probe 32, after the person stands up and leaves the sensing area of the second probe 33, the second probe 33 sends a sensing signal, and the signal is transmitted to the flushing system of the toilet 1 to open a flushing valve for flushing after sitting. And in 10 seconds after the second probe 33 senses and sends out the signal, namely in the time that the person stands up far away, the first probe 32 is in an un-sensing state, so that the waste of water resources caused by the fact that the person is flushed after the second excrement is formed by the sensing of the first probe 32 in the process of standing up far away is avoided. The second probe 33 is inclined at 45 degrees, so that the back of the user can be in the sensing area of the second probe 33 when the user squats down, and the sensitivity can be better improved. In addition, when the first probe 32 and the second probe 33 have no sensing action within 24 hours, the flushing system of the toilet 1 can automatically open the flushing valve so as to prevent the water stored in the water trap of the toilet 1 from drying up, and thus the odor is prevented from flowing back.

In addition, as shown in fig. 2 and 4, the first sensing window 211 and the second sensing window 212 are respectively provided with a first window board 22 and a second window board 23, and the first window board 22 and the second window board 23 can play a role in protecting the sensing probe 3, so that the sensing probe 3 is prevented from being in contact with moist air in a toilet in the use process, corrosion and rust of the sensing probe 3 are caused, the sensing precision and the service life of the sensing probe 3 are affected, and the sensing probe 3 is further protected. And the first and

second louvers

22 and 23 are made of a transparent material such as: the synthetic plastic is made, so that the induction probe has good protection effect, and the first window plate 22 and the second window plate 23 are prevented from obstructing the induction of the induction probe 3, so that the induction precision, sensitivity and accuracy of the induction probe 3 are ensured.

As shown in fig. 5 and 6, the outside of the induction probe 3 is provided with a positioning block 4, the width dimension of the positioning block 4 is slightly larger than the width dimension of the mounting frame 24, the positioning block 4 is made of elastic materials, when the induction probe 3 is placed in the mounting frame 24, the positioning block 4 is compressed and embedded in the mounting frame 24, and when in operation, the induction probe 3 is clamped in the mounting frame 24 by using the elastic restoring force of the positioning block 4, so that the fixing connection of the mounting frame 24 and the induction probe 3 is realized, and when the shell 2 and the mounting frame 24 are not impacted, the positioning block 4 can play a certain buffering protection role on the induction probe 3, so that the induction probe 3 is prevented from being damaged by impact force, and the service life of the induction probe 3 is prolonged.

When in use, after a human body enters the sensing area of the first probe 32, the first probe 32 sends out a sensing signal, the signal is transmitted to the flushing system of the toilet bowl 1, a flushing valve in the flushing system is opened to flush water before the toilet bowl is used, then a user walks away if standing the toilet bowl 1, and after the user leaves the sensing area of the first probe 32, the first probe 32 sends out a sensing signal again, the signal is transmitted to the flushing system of the toilet bowl 1, the flushing valve is opened to flush water after the toilet bowl is used. When the user uses the toilet 1 before sitting down, the user enters the sensing area of the second probe 33, and gets away from the sensing area of the first probe 32, after the user stands up and walks away from the sensing area of the second probe 33, the second probe 33 sends out a sensing signal, and the signal is transmitted to the flushing system of the toilet 1, so that the flushing valve is opened to flush after sitting down. And in 10 seconds after the second probe 33 responds to the signal, namely in the time that the people stand up to walk away, the first probe 32 is in the non-response state to avoid the people to be stood up to walk away the in-process by the first probe 32 response formation secondary after-flush, cause the waste of water resource, simple structure, the simple operation utilizes the inductive action of first probe 32 and second probe 33, realize the automatic before-the-counter flush and the after-the-counter flush of stool pot 1, need not manual operation, avoid the bacterium cross infection that the indirect contact of user arouses, play the purpose of using water wisely and keeping clean and sanitary, and keep stool pot health that just can be fine.

The foregoing is merely illustrative of specific embodiments of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial modification of the present utility model by using the design concept shall fall within the scope of the present utility model.
