BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a touch spray head which turns on/off water in a manual operation manner.
Description of the Prior Art
A conventional control valve for a spray head of a faucet is manufactured at high cost and is complicated. Accordingly, improved touch control valves were disclosed in TW Patent Nos. M432670, 1228578, 1369459, M452280 and M382408, respectively. The improved touch control valves are an automatic valve or a manual valve, wherein when the touch control valves are the manual valve, water supply is stopped by touching an actuation element, after starting the water supply. When the touch control valves are the automatic valve, the water supply is stopped automatically by way of water pressure change after a period of using time.
In addition, one touch control valves are sold by many companies, such as 3M, wherein each one touch control valve is fixed on an outlet of the faucet and the water supply is started or stopped by manually touching an actuation element in the control valve, thus causing contamination to the actuation element.
A conventional faucet contains a handle and a central shaft driven by the handle so as to control water supply or to adjust temperature of the water supply. But an operation travel is too long to operate the faucet smoothly and to obtain aesthetics appearance of the control valve.
Another conventional faucet contains an infrared sensor disposed on a body so as to sense user's hand by which water is supplied, yet the conventional faucet cannot be controlled as the infrared sensor or a circuit board is broken.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

Referring to FIG. 32, the tubular part 41c has an aperture 411c defined therein, multiple troughs 412c separately arranged on an inner wall of the first aperture 411c, and multiple tilted positioning teeth 413c. As shown in FIGS. 38-40, the press member 42c is fitted in the aperture 411c of the tubular part 41c, the press member 42c includes a plurality of slide protrusions 424c formed on an outer wall thereof and slidably retained with the multiple troughs 412c respectively, and the press member 42c includes multiple tilted actuating teeth 425c formed on the abutting segment 422c; the rotating member 43c has a first post 433c extending outwardly from a first end thereof and rotatably fitted with the first opening 231c of the fixing cylinder 20, a second post 434c extending outwardly from a second end of the rotating member 43c and rotatably fitted with the second opening 423c of the press member 42c, the action zone 430c formed between the first post 433c and the second post 434c, and multiple tilted driven teeth 435c arranged between the action zone 430c and the second post 434c. The toothed drive mechanism 45c is comprised of the multiple tilted positioning teeth 413c of the tubular part 41c, and the multiple tilted actuating teeth 425c of the press member 42c, and the multiple tilted driven teeth 435c of the rotating member 43c.
When the press member 42c is pressed to move or is released, the multiple tilted actuating teeth 425c push the multiple tilted driven teeth 435c of the rotating member 43c to move away from the multiple tilted positioning teeth 413c of the tubular part 41c, and the resilient element 44c pushes the multiple tilted driven teeth 435c to rotatably fix on the multiple tilted positioning teeth 413c individually, hence the rotating member 43c rotates in the travel.
Each of the multiple acting portions 431c is an elongated rib; each of the multiple non-acting portions 432c is an elongated slot, and the multiple acting portions 431c abut against the operation bar 31 of the water valve 30 via the push column 50, when the press member 42c is pressed or is released, as shown in FIG. 36.
Furthermore, each non-acting portion 432c is configured to remove the operation bar 31 from the push column 50.
After pressing and releasing the press member 42c, the press member 42c moves back to an original position by way of the resilient element 44c and the toothed drive mechanism 45c, and the rotating member 43c moves back to the multiple non-acting portions 432c relative to the push column 50.
In this embodiment, the resilient element 44c is a compression spring and is fitted on the second post 434c of the rotating member 43c, wherein a first end of the resilient element 44c abuts against a part of the peripheral fence 23c of the fixing cylinder 20, and a second end of the resilient element 44c is biased against a stop cliff 436c between the action zone 430c and the first post 433c, as illustrated in FIG. 8.
With reference to FIG. 32, the tubular part 41c has six troughs 412c and six tilted positioning teeth 413c, wherein an inner end of each of the six troughs 412c is defined by a lowest portion of each of the six tilted positioning teeth 413c. The press member 42c has six slide protrusions 424c and six tilted driving teeth 425c. The rotating member 43c has three tilted driven teeth 435c, wherein tilting directions and slopes of the six tilted positioning teeth 413c, the six tilted driving teeth 425c, and the three tilted driven teeth 435c are identical, hence after the press member 42c is pressed and is released, the rotating member 43c revolves in a travel of 60 degrees, for example, the rotating member 43c revolves from an imaginary position of the FIG. 33 to an imaginary position of FIG. 34. In other words, when the rotating member 43c revolves in a circle, it means that the rotating member 43c revolves in six travels, and each of the six travels is 60 degrees.
Referring to FIGS. 32-34, the six troughs 412c of the tubular part 41c has three deep troughs 414c and three shallow troughs 415c which are spaced from one another respectively, wherein the three tilted driven teeth 435c of the rotating member 43c slide into the three deep troughs 414c individually, as shown on the imaginary position of FIG. 34. The rotating member 43c has three limitation cliff 437c spaced from one another by the three tilted driven teeth 435c respectively, hence after the three tilted driven teeth 435c slide into the three deep troughs 414c individually, the three tilted driven teeth 435c are fixed by the three limitation cliff 437c and the six tilted positioning teeth 413c respectively, as illustrated in FIG. 35.
In addition, a distal end of the extension 52 of the push column 50 is driven by the multiple acting portions 431c of the rotating member 43c.
Referring to FIGS. 33-35, the touch spray head 1c further comprises a compression spring 60 configured to push the push column 50 to move back to an original position, after the rotating member 43c rotates in every travel.
With reference to FIGS. 47-50, a difference of a touch spray head 1d of a fifth embodiment from that of the first embodiment comprises:
an accommodation chamber 22d formed in the receiving zone 203 of the fixing cylinder 20.
Referring to FIGS. 50, 53, and 54, the manual operation device 40 is a magnetic drive device 404 which includes a moving portion 41d housed in the accommodation chamber 22d and moving between a pressing position and a releasing position, wherein the moving portion 41d has a urging section 411d extending out of the through hole 13 of the casing 10 so as to be pressed by the user; an elastic element 42d configured to elastically act on the moving portion 41d so that the moving portion 41d stays at the pressing portion or returns back to the releasing position, as shown in FIG. 48; a first magnetic element 43d fixed on the moving portion 41d; a second magnetic element 44d movably accommodated in the fixing cylinder 20 and opposite to the operation bar 31 of the water valve 30, wherein when the moving portion 41d is pressed to move to the pressing position, it is magnetically driven by the second magnetic element 44d to touch the operation bar 30 to move, as shown in FIG. 55.
As shown in FIGS. 51-52, the second magnetic element 44d is accommodated in the groove 25 opposite to the operation bar 31.
When the moving portion 41d is located at the pressing position, the first magnetic element 43d closes to the second magnetic element 44d so as to repel against the second magnetic element 44d, hence the second magnetic element 44d is driven to movably touch the operation bar 31, as illustrated in FIG. 55. When the moving portion 41d is located at the releasing position, the first magnetic element 43d moves away from the second magnetic element 44d so as to decrease or vanish repulsion force between the first magnetic element 43d and the second magnetic element 44d, hence the second magnetic element 44d removes from the operation bar 31, as shown in FIG. 48.
Each of the first magnetic element 43d and the second magnetic element 44d is a magnet so that the first magnetic element 43d repels against the second magnetic element 44d, hence the second magnetic element 44d is driven to move back to an original position.
With reference to FIGS. 48 and 51, the accommodation chamber 22d has a guiding trench 231d defined thereon, the moving portion 41d has a press member 45d and a slider 46d connecting with the press member 45d; the press member 45d has the urging section 411d formed thereon; the slider 46d has a slidable peg 412d rotatably retained and moving in the guiding trench 231d, and the slider 46d has a mounting portion 413d configured to fix the first magnetic element 43d. The guiding trench 231d includes a first tangent plane formed on an inner wall thereof, and the slidable peg 412s has a second tangent plane formed on an outer wall thereof and mating with the first tangent plane, thus limiting rotation of the slider 46d. Thereafter, the first magnetic element 43d moves close to or away from the second magnetic element 44d straightly and does not rotate.
Referring to FIGS. 48, 53, and 54, the press member 45d has an extending segment 414d extending from the urging section 411d; the slider 46d has a first cutout 415d configured to accommodate the extending segment 414d, and the mounting portion 413d further has a second cutout 416d configured to house the first magnetic element 43d; the mounting portion 413d abuts against a part of the housing 10 inside an outer rim of the through hole 13 of the casing 10 so as to fix the moving portion 41d at the releasing position.
The moving portion 41d has a first biasing fringe 417d defined on one side thereof opposite to a distal end of the slidable peg 412d; the fixing cylinder 20 further includes an affixing tube 232d and a second biasing fringe 233d which are formed on the guiding trench 231d of the accommodation chamber 22d; the elastic element 42d is a compression spring fitted on the slidable peg 412d of the slider 46d and the affixing tube 232d, and two ends of the elastic element 42d abut against the first biasing fringe 417d and the second biasing fringe 233d respectively.
Referring to FIGS. 48 and 50, the compression spring 60 is accommodated in the groove 25 between the water valve 30 and the second magnetic element 44d so as to decrease or vanish repulsion force between the first magnetic element 43d and the second magnetic element 44d, hence the first magnetic element 43d and the second magnetic element 44d move back to original positions individually.
When the water valve is automatic, the operation bar 31 is driven to move so as to flow the water. Thereafter, the water valve moves back to an original position and turn off the water, hence turning off the water by pressing the driving portion 40a of the manual operation device 40 is not required.
When the water valve 30 is not automatic, it is turned off by manually pressing the driving portion 40a of the manual operation device 40.
Thereby, the operation bars 31 of the water valves 30 of the touch spray heads 1, 1a, 1b, 1c, 1d are driven by operating the driving portion 40a of the manual operation devices 40, thus starting/stopping the water supply easily and saving water consumption.
The water valves 30 of the touch spray heads 1, 1a, 1b, 1c, 1d are driven by operating the manual operation devices 40 so as to avoid manually touching and contaminating the water valves 30.
The touch spray heads 1 spray the water in different water spraying modes by way of the switch valve assemblies 70.
The pressing button 400 of the touch spray head 1 of the first embodiment is rotatably connected with the fixing cylinder 20 directly so as to simplify the touch spray head 1 and reduce fabrication cost.
The inflow connectors 91 of the outlets 2a of the touch spray heads 1, 1a, 1b, 1c, 1d are screwed with the screw sleeves 92 respectively. Alternatively, each inflow connector 91 has a protruded section 912 formed thereon and has at least one engagement projection 913 arranged around an outer wall of the protruded section 912, as shown in FIG. 56, and each screw sleeve 92 has at least first indentation 921 defined on an inner wall thereof and has at least one second indentation 922 communicating with the at least one first indentation 921 so that the protruded section 912 of each inflow 91 extends out of the top of the casing 10, and the at least one engagement projection 913 rotates into the at least one first indentation 921 and retains in the at least one second indentation 922, thus connecting/removing each screw sleeve 92 with/from each inflow connector 91 quickly so as to replace or maintain each touch spray head 1, 1a, 1b, 1c, 1d freely.
