The electronic faucet that is equipped with photocell, proximity transducer etc. is well-known in the art and only allows the current of for example, just providing and delivering when the existing of user or device (, glass) being detected.
These leading advantages are that they are conducive to the water outlet when for example hand is dirty, and health and clean is not only provided, and water saving.
Conditional electronic as known in the art tap (patent No. US20090094740, patent No. FR2761446) comprises by adopting battery-powered automatic vertical (vertically) and/or provide and deliver current have the system of manual-operated emergent function of face sensor just.Yet these taps have very complicated member, they make installation, battery altering and jet pipe rotate difficulty.In fact, many members are positioned at the below of tank panel, make installation and maintenance very complicated, and only can be carried out by technician.
In view of above situation, obviously need a kind of scheme, this scheme can comprise for to have overcome the suitable equipment of best mode dispensing current of the shortcoming of known technology " electronics " tap.
Accompanying drawing explanation
Now specifically but nonrestrictive embodiment preferred with reference to accompanying drawing utilization illustrates the present invention, in the accompanying drawings:
-Fig. 1 illustrates the phantom drawing that does not purely limit the scope of the invention for purposes of illustration this leading shape of selecting, and wherein tap has vertical reference (1) and positive face sensor (2);
-Fig. 2 illustrates the sectional view of the structure with its whole members and their relative optimal placement of tap;
-Fig. 3 .1 and 3.2 illustrates for battery and is installed in top, two sensors (positive face sensor (2) and vertical reference (1)) of head wherein and two phantom drawings that show the LED (14) of operation and low battery electric quantity;
-Figure 4 and 5 illustrate respectively the phantom drawing of leading inside and the section of jet pipe, show the bypass (17) forming according to the present invention;
-Fig. 6 illustrate according to the present invention form for inserting the phantom drawing of the head rest supporting body (20) of positive face sensor and/or vertical reference.
The specific embodiment
This structure is example preferred but non-limit; Can see, head comprises with the glass disk of nature or color background (15), wherein utilizes laser or abrasive machine (grinder) to be formed with otch (23), and therefore described disk becomes transparent in incision tract.The color of this disk can be identical with jet pipe.
At head (15), the LED retainer (22) for sensor is installed.Then the sensor (21) with electronic control circuit is inserted into again in LED retainer (22).This whole unit is then in position by head rest supporting body (20) and keep together, and described head rest supporting body also keeps battery (7), thereby is conducive to change.Infrared ray sensor (21) therefore can see through otch (23) and work rightly, thereby obtains " on-off " function for tap.This makes head have sightless optical pickocff, and the problem of bringing due to scraping and the fault that causes thereupon especially can not occur described optical pickocff, because glass is compared very durable with commercially available other traditional sensors on the market.
The very important point relevant with head is that it has the very outward appearance of pleasant, identical with water delivery jet pipe because stained glass (15) can manufacture tone.
In Fig. 3 .1, can see for example red LED (14), it detects dispensing in one's hands or object and water for showing, or the electric weight of pilot cell (7) is low.
This LED also available back light system (referring to Fig. 3 .1 and 3.2, and Reference numeral 16) replaces, and described back light system makes with the head of positive face sensor pleasant and noticeable more.In this case, the LED retainer (22) in Fig. 6 is taken in a plurality of LED (14), and described a plurality of LED produce soft, vivid, very fashionable effect together while lighting.
Head can be used 1.5 volts of alkaline battery work, and this battery is most economical and general in the whole world.They are combined in the inside of jet pipe, are positioned at the region of proximity sense, are therefore in the position that is easy to arrival for replacing.
By all electronic components being all arranged in head and by header arrangement in jet pipe (4), to compare with the known tap of prior art, jet pipe (4) can be around himself rotating 360 degrees freely.Therefore, in connection with the head that is useful on the operating system of current, insert completely in faucet sprayer nozzle and represented real innovation, it makes installation, maintenance and battery altering not only quick, no problem, and very simple.
Therefore, tap is inner not to be existed and can reverse and the line of fracture, in some utilizes the existing tap of conventional electric power transformer, there will be this situation.
Install easy and simply can understand and utilize flexible pipe (10), flap valve (11) and realize with the details that can check the plug valve (12) of the strainer of impurity water from Fig. 2.
The utility of this scheme is apparent.Further innovation of the present invention is manual water outlet utilize the temporary transient emergent possibility of bypath system when head cannot be worked due to running down of battery.Figure 4 and 5 illustrate screw (17), and this screw is used screwdriver (19) or coin to rotate half-turn also as the water bypass with electromagnetic valve (9) concurrent working.In fact, as known in the art, rotable nozzle (4) also rotates the screw (17) that is positioned at jet pipe rear rather than tank panel below, and this makes operation very simple and feasible for everyone.
Screw (17) is as the bypass of the electromagnetic coil (8) that replaces cannot working owing to lacking energy when the running down of battery.Barrier film in electromagnetic valve (9) be raised and here water flow out continuously.
Fig. 2 shows the example of not limited field of the present invention, wherein all members so far appropriate location of the structure of described electronic faucet that has all been shown as consideration in them.The object of having stated for example with preferred form of structure and do not described the present invention limited field; Any remodeling of the device shown in the present invention includes and described method and other modification and as in claims described in other application of the principle of the present invention that conventionally can expect of those skilled in the relevant art of the present invention.
Claims (according to the modification of the 19th of treaty)
