The water outlet of order-driven electrically operated valve shut-off gondola water faucet processed.
Pass through above-mentioned alternative embodiment, it is possible to achieve when gondola water faucet lands in abnormal cases, control gondola water faucet is automatically stopped
Water outlet, avoid making troubles for user.
In a kind of optional embodiment, as shown in Fig. 2 gondola water faucet also includes：Button 5 is set, forbidden for opening setting
The function of water outlet scope；If processor, which is additionally operable to press, sets button 5, sign on is generated；If processor is additionally operable to lift
The setting button 5 pressed is acted, generates halt instruction.
Specifically, above-mentioned setting button is arranged on gondola water faucet, waterproofing membrane button can be, but not limited to.
Specifically, above-mentioned sign on is used for the anglec of rotation for controlling gondola water faucet start recording gondola water faucet water outlet mouth, above-mentioned stopping
Instruct the anglec of rotation for controlling gondola water faucet stop recording gondola water faucet water outlet mouth.
In a kind of optional embodiment, illustrated so that gondola water faucet is Portable rose as an example, as shown in figure 5, where user
Toilet in, wash platform can be provided with, bathing area, bathing area top are provided with Portable rose, the wall due to toilet
On hang with user's clean clothing to be used instead, user can set clothing region to forbid gondola water faucet water outlet scope.
User need to set it is as shown in Figure 5 forbid gondola water faucet water outlet towards when, user only needs Portable rose, is worked as with gondola water faucet
Centered on front position, the water outlet direction of shower head capable rotating, when enter access customer need to forbid gondola water faucet water outlet towards scope when, press setting
Setting button on gondola water faucet, microprocessor generation sign on, gyroscope receive sign on, and gyroscope starts collection flower
Spill the anglec of rotation at the mouth of a river, when exiting gondola water faucet and forbidding water outlet towards scope, user, which unclamps, sets button, microprocessor generation
Halt instruction, gyroscope receive above-mentioned halt instruction, the anglec of rotation of stop recording gondola water faucet water outlet mouth.
In a kind of optional embodiment, as shown in Fig. 2 gondola water faucet also includes：Reset key 6, for recovering gondola water faucet water outlet
The function of mouth water outlet；If processor is additionally operable to press reset key, generation recovers instruction.
Optionally, above-mentioned reset key 6 is arranged on gondola water faucet, can be, but not limited to waterproofing membrane button, and above-mentioned recovery refers to
Make for controlling the salty new water outlet of gondola water faucet water outlet.
As a kind of optional embodiment, when user is during bathing, when there are abnormal conditions, as gondola water faucet quickly falls
Fall, processor detects that the acceleration of motion of accelerometer is identical with free-fall acceleration, the finger of generation shut-off gondola water faucet water outlet
Order, control gondola water faucet stop water outlet, can be by dividing into when user picks up the Portable rose on ground, it is necessary to when recovering gondola water faucet water outlet
The reset key on gondola water faucet is put, for processor in the case where detecting the reset signal that reset key is sent, generation recovers flower
Spill the recovery instruction of water, gondola water faucet recovers water outlet again.
In a kind of optional embodiment, as shown in Fig. 2 gondola water faucet also includes：Enabled button 7, for cancelling gondola water faucet
The control of water scope；If processor is additionally operable to press enabled button 7, uploads and cancel instruction.
