The flow regulator of Fig. 6 and structure shown in Figure 7 is when the feedwater pipe arrangement side that this sensor controlling type automatic faucet is installed is not equiped with flow rate regulating valve, is to be linked to the feedwater pipe arrangement with the form that directly is linked to sensor controlling type automatic faucet.At this moment, flow regulator is to be designed to slim shape, even flow regulator is arranged to the state showed out from the plate of the wall or the platen that washes one's face, can be tending towards simple with overall appearance after the combination of sensor controlling type automatic faucet.And, under common installment state,, just can adjust flow though be to open upper shell, must utilize the instrument of special uses such as screwdriver to carry out required flow adjustment, can prevent that not specific other people from random changing flow.

The utility model compared with prior art has tangible advantage and good effect.Can be in the worker finish and have height reliability owing to the integral body of its sensor controlling type automatic faucet, can simplify distribution and the installation exercise of the various scene of restriction when installing significantly with regard to assembling.

And, installation aspect about sensor controlling type automatic faucet, for feedwater pipe arrangement side almost without limits, so when newly adding sensor controlling type automatic faucet equipment, the degrees of freedom of PIPING DESIGN is very big, in addition, if when the desire row is replaced existing manually operated type water tap, then can quote existing feedwater pipe arrangement, needn't change pipe arrangement and just can finish installation.

In addition, have nothing to do with installation site, pipe arrangement form, since the result of commonization of structure of sensor controlling type automatic faucet, a large amount of productions of practicable single machine.Therefore, can provide cheap goods, simultaneously also applicable to carry out the automation assembling with the industry robot because of the expense of saving mould.

In addition, when being made into solenoid valve is given province's electrification, and control circuit and sensor all drive with common battery, and with common battery container in housing, and the outside wiring of the usefulness that need not to power the time, as long as pull down original old water tap, this sensor controlling type automatic faucet can use immediately just directly connect upward.

At this moment, the distribution that does not have outside, can make because the fault that the corrosion of distribution broken string is caused, because of joint partly the possibility of the electric leakage due to the dewfall disappear all, textural making needn't be pulled out distribution from housing again, and then, the outward appearance of configuration status more is tending towards succinctly, can enlarge the degrees of freedom in the article shape design.

Sensor controlling type automatic faucet, because the outlet side pipeline is integrally formed with the box structure that is used for accommodating control circuit, can cut down the assembling quantity of being assembled in the housing, can increase the degrees of freedom in the configuration of screw, seal construction, can be via the miniaturization of each accessory, and the exquisiteness arrangement in the configuration, make the outward appearance of sensor controlling type automatic faucet be tending towards succinctly, and miniaturization, lightweight.

In addition, the outlet side pipeline is disposed at the below of control circuit, can not produce because of the dewfall of outlet side pipeline drippage influence control circuit, sensor, and the containing space of control circuit itself just constitutes the thermal insulation construction of outlet side pipeline, so the dewfall amount itself around the outlet side pipeline is with regard to seldom.And the material thickness that also can reduce the outlet side pipeline is to save material, and thermal insulation construction, the area coverage that can just get the outlet side pipeline all comparatively reduce.

Sensor controlling type automatic faucet, across the containing space setting battery holding part of control circuit, so the heat of the fluid in the outlet side pipeline can not influence to battery above the outlet side pipeline, so can not dewfall.That is, battery is to be held in the driest and position that temperature variation is minimum in the housing, therefore can not take place because of the short circuit that dewfall caused at battery contact place or the problem of the shorter battery life that Yin Gaowen caused.

Sensor controlling type automatic faucet just can change battery immediately as long as lift upper shell, so the exchanging operation of battery is very simple, and needed time is also few.
