Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.

[0013] In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

[0014] Referring to FIGS. 1 to 4, the present invention provides a drinking water faucet which comprises a main body (10), a sensor (20), a threaded tube (30), a locating unit (40), a solenoid valve (50) and a water outlet tube (60), and the locating unit (40) further has a first locating member (41), a second locating member (42) and at least two bolts (43). The main body (10) is a shell and has a lower opening (101), an interior housing (102), and an upper opening (103), which are communicated with each other, and a diameter of the upper opening (103) is smaller than the lower opening (101). A window (104) is formed at a front side of the main body (10), and the sensor (20) installed inside the interior housing (102) of the main body (10) is located at a position corresponding to the window (104). After the sensor (20) is installed inside the interior housing (102), a cover (11) is engaged with the lower opening (101) to block a lower end of the main body (10). Moreover, a through hole (111) is configured to axially penetrate through a central portion of the cover (11). The threaded tube (30) comprises a discharge section (31) and a passage section (32), and a first threaded section (311) and a second threaded section (321) are respectively formed on outer peripheries of the discharge section (31) and the passage section (32). The discharge section (31) is inserted through the through hole (111) of the cover (11) into the interior housing (102) of the main body (10), and the first threaded section (311) is configured to engage with the upper opening (103) to position the discharge section (31) inside the upper opening (103). A lower portion of the passage section (32) protruding from the lower end of main body (10) is configured to penetrate through an install hole (71) of a table (70), and the second threaded section (321) of the passage section (32) is adapted to sequentially engage with the first locating member (41) and the second locating member (42). Furthermore, at least a locating annular groove (312) is formed inside the discharge section (31) of the threaded tube (30), and at least two screw holes (421) vertically penetrate through the second locating member (42) of the locating unit (40). The two bolts (43) are configured to screw in the two screw holes (421) respectively to abut against a bottom portion of the first locating member (41), thereby securing positions of the first locating member (41) and the second locating member (42). The solenoid valve (50) having a first channel (501) and a second channel (502) is installed under the table (70), and the first channel (501) and the second channel (502) are respectively connected to a drinking water supply and the passage section (32) of the threaded tube (30). Additionally, the solenoid valve (50) is electrically connected to the sensor (20) such that the sensor (20) is configured to control on/off operation of the solenoid valve (50). The water outlet tube (60) comprises a connecting section (601) formed at an end thereof, and at least a sealing ring (61) is disposed on the connecting section (601). The water outlet tube (60) is configured to downwardly insert through the upper opening (103) of the main body (10) into the discharge section (31) of the threaded tube (30), and the sealing ring (61) is configured to couple in the locating annular groove (312), thereby locating a position of the water outlet tube (60).

[0015] In one embodiment, the through hole (111) of the cover (11) is a hexagonal hole.

[0016] In another embodiment, the sensor (20) is an infrared sensor.

[0017] In still another embodiment, a neck section (33) is configured to be connected between the discharge section (31) and the passage section (32), and a diameter of the neck section (33) is smaller than the discharge section (31) and the passage section (32).

[0018] In a further embodiment, the first locating member (41) is a face-up lid having a first opening at a top end thereof, and a second opening (411) formed at a lateral wall of the first locating member (41) is configured to be passed through by a power cord of the sensor (20).

[0019] In still a further embodiment, the second channel (502) of the solenoid valve (50) is connected to the passage section (32) of the threaded tube (30) through an adapter (51).

[0020] In yet a further embodiment, the drinking water faucet of the present invention is installed on the table (70).

[0021] In a preferred embodiment, the table (70) is a kitchen countertop.

[0022] Comparing with conventional drinking water faucet, the present invention is advantageous because: (i) a user can get drinking water through a sensing method, thereby preventing the risks of electric shock and spread of bacteria; and (ii) with at least two bolts (43) screwed in the screw holes (421) of the second locating member (42), the first locating member (41) and the second locating (42) are configured to be firmly engaged on the passage section (32) of the threaded tube (30), which improves the structural strength of the drinking water faucet.

[0023] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
