Description

A kind of induction structure for closet and induction urinating bucket

Technical field

The utility model relates to bathroom field, especially a kind of induction structure for closet and induction urinating bucket.

Background technique

Currently, existing urinating bucket inductor in the market, mostly based on traditional infrared induction.It is main former referring to Fig. 1 Reason is: when certain of the hand of human body or body a part enter infrared spectral range in when, infrared emission tube issue infrared ray by Gear is picked up in human body hand or body and is reflected into infrared receiver tube, and reception pipe converts optical signals into electric signal and is sent in control panel MCU, MCU presses pre-set programs, sends signal and be sent to solenoid valve, and solenoid valve, which is opened, carries out primary pre- bath；When the hand of human body Or body leaves infrared induction range, infrared receiving tube optical signal disappears, and MCU does not receive electric signal, determine user from It opens, MCU sends a signal to solenoid valve, and bath is primary, completes one-time detection bath process.

Existing infrared induction urinating bucket, inductor have following three:

First is that it is insensitive to dark colour object, it is easy to cause leakage inductance to answer.

Second is that needing out an infrared window, product beauty is influenced.

Third is that the object that it incudes is people, and the first pre- bath as long as sensing that someone comes, after people leaves, one more flushing Water.This detection mode is more rough, because people only stay before urinating bucket sometimes, there is no urine, but urinal is also It is to wash by water by example, causes water resource waste.

In recent years, with the development of induction technology, also occur some concealed inductors (such as Fig. 2) in the market, place Onto 1 rear side ceramic wall of urinating bucket, when urine flows through sensing element, inductor 2 can detect that urine flows, to control electromagnetism Valve bath cleaning.

There is also some problems for existing concealed inductor, such as:

1, referring to Fig. 3, in falling urine point nine grids test, the 2nd lattice only above the 5th lattice of inductor installation site and its Inductor just has reaction when place falls urine, and when falling urine in other 1,3,4,6,7,8,9 seven lattice, inductor does not all react.

2, in wider test, referring to Fig. 4, also only the area Luo Niaodian A point and its surface Shi Caineng are sensed, are fallen When urinating B of the area in other regions such as side and falling the C in urine point and front and fall urine point, induction module does not also react.

According to we investigate as a result, people are in the normal use inductor, urine does not flow a possibility that there are about 40% Sensed area.The situation failed to judge that someone's urine will occur, but not wash by water, to influence user experience and toilet gas Taste.

Utility model content
