In this embodiment, the spray assembly 25, the inflow member 26, the guiding member 27, the seal pad 28, and the rotating piece 29 are used to flow water through the first, the second, the third, and the fourth lower chambers 243, 234a, 234b, 234c to generate water flower in bubbled, jetted, massaged, and linear watering modes.
The inflow member 26 and the guiding member 27 are installed to upper and lower sides of the second lower chamber 234a and includes a number of apertures 261, 271 so that water in the second lower chamber 234a flows through the apertures 261, 271 and the nozzles 251b of the internal spraying member 251 to generate water flower in the jetted watering mode. Because the inflow member 26 and the guiding member 27 are well known, further remarks are omitted.
The seal pad 28 and the rotating piece 29 are installed to the third lower chamber 234b, wherein the seal pad 28 includes a plurality of apertures 281 arranged thereon, and the rotating piece 29 has a length equal to 1/4 of impeller and a number of vanes 291 so that the water flows to the third lower chamber 234b to impact the vanes 291 of the rotating piece 29, hence the rotating piece 29 rotates along the seal pad 28 freely so as to stop the apertures 281 of the seal pad 28 intermittently, generating intermittent watering to have a massage. Because the seal pad 28 and the rotating piece 29 are well known, further remarks are omitted.
The plugs 30 are disposed to the slots 12 of the holder 10, and each has an opening 31 formed therein and a compression spring 32 to abut against the upper disc 21 of the distributing set 20. When the upper disc 21 rotates relative to the holder 10, the opening 31 of the plug 30 communicates with one set of the inlet 211 of the upper disc 21 to guide water from the passage 11 of the holder 10 to the inlet 211 to spray water flower in a predetermined mode, such as bubbled, jetted, massaged, and linear watering mode. It is to be noted that the plug 30 allows to communicate with two sets of inlets 211 so that water from the passage 11 of the holder 10 is guided to the two sets of inlets 211, generating water flower in double watering mode, such as massaged and bubbled, bubbled and jetted, jetted and linear, and linear and massaged watering mode.
With reference to Figs. 2 and 3, the rotable positioning structure 40 includes a levering pin 41, a compression spring 411, a receiving groove 42, and a plurality of engaging orifices. The receiving groove 42 is disposed on the outflow side of a bottom surface of the holder 10 to receive the compression spring 411 and the levering pin 41 pushed by the compression spring 411; the engaging orifices are located at the concentric point of the inlets 211 to be retained by the levering pin 41, wherein the upper disc 21 includes eight engaging orifices to be divided into two areas, one area is a first rotary zone 43 and a second rotary zone 44 as shown in Fig.
7; the first rotary zone 43 includes four engaging orifices, e.g., a first, a second, a third, and a fourth engaging orifices 431, 432, 433, 434; the second rotary zone 44 includes four engaging orifices, e.g., a first, a second, a third, and a fourth engaging orifices 441, 442, 443, 444; between any two adjacent engaging orifices in the first and the second rotary zones 43, 44 is formed a 45 degree of first angle, and between the fourth and the first engaging orifices 434, 441 is formed a 22.5 degree of second angle.
The angle between the two adjacent engaging orifices of the first rotary zone 43 is equal to that between anyone set of inlet 221 so that as the levering pin 41 displaces from anyone engaging orifice of the first rotary zone 43 to another adjacent engaging orifice, the openings 31 of the plugs 30 of the holder 10 displace from one set of inlet 211 of the upper disc 21 to another set of inlet 211 adjacent to the one set of inlet 211 of the upper disc 21. In other words, as the levering pin 41 abuts against the first, the second, the third, the fourth engaging orifices 431, 432, 433, 434 of the first rotary zone 43 in order, the openings 31 of the plugs 30 communicate with the four sets of inlets 211 of the upper disc 21, generating water flower in the bubbled, jetted, massaged, and linear watering mode.
The angle between the fourth engaging orifice 434 of the first rotary zone 43 and the first engaging orifice 441 of the second rotary zone 44 is designed to 22.5 degrees so that as the levering pin 41 rotates from the fourth engaging orifice 434 to the first engaging orifice 441, the openings 31 of the plugs 30 of the holder rotates from one set of inlet 221 of the upper disc 21 to the two sets of inlets 211.
Besides, the angle between any two adjacent engaging orifices of the second rotary zone 44 is 45 degrees, therefore when the levering pin 41 contacts with the first, the second, the third, and the fourth engaging orifices 441, 442, 443, 444 of the second rotary zone 44, the openings 31 of the plugs 30 communicate with the two sets of inlets 221 to spray water flower in massaged and bubbled, bubbled and jetted, jetted and linear, linear and massaged double watering mode. Accordingly, the first and the second rotary zones 43, 44 are designed based on the number of the watering mode.
For example, as the levering pin 41 is located at any engaging orifice of the first rotary zone, only one watering mode is obtained, however, as the levering pin 41 is located at any one engaging orifice of the second rotary zone 44, a double watering mode is achieved.
The adjustable levering assembly 50 includes four fixing projections radially extending from an peripheral side of the holder 10, and a rotor 52 extending upward form a top surface of the upper disc 21 of the distributing set 20; the fixing projections are a first, a second, a third, and a fourth stators 511, 512, 513, 514, and an angle between the first and the second stators 511, 512 is 90 degrees, an angle between the second and the third stators 512, 513 is 67.5 degrees, an angle between the third and the fourth stators is 90 degrees.
As shown in Fig. 12, before the assembly of the distributing set 20 and the holder 10, the rotor 52 is limited between the first and the second stators 511, 512 to rotate so that as the rotor 52 is biased against the first stator 511, the levering pin 41 of the rotable positioning structure 40 abuts against the first engaging orifice 431 of the first rotary zone 43, hence when the rotor 52 rotates 90 degrees from the first stator 511 toward the second stator 512, the levering pin 41 rotates from the first engaging orifice 431 to the third engaging orifice 433 via the second engaging orifice 432 as illustrated in Fig. 11 to achieve three single watering modes, e.g., bubbled, jetted, and massaged watering mode.
Referring further to Fig. 13, before the assembly of the distributing set 20 and the holder 10, the second stator 512 is manually removed or cut by tool in advance.
Thereafter, the rotor 52 is additionally rotated 67.5 degrees to be up to 157.5 degrees so that a rotor 41 is rotated 157.5 degrees from the first engaging orifice 431 of the first rotary zone 43 to pass through the second, the third, and the fourth engaging orifices 432, 433, 434 toward the first engaging orifice 441 of the second rotary zone 44 as illustrated in Fig. 11 to generate four single and one double watering modes, such as bubbled, jetted, massaged, linear, and massaged and bubbled watering modes.
With reference to Fig. 14, before the assembly of the distributing set 20 and the holder 10, the second and the third stators 512, 513 are removed so that the rotor 52 is additionally rotated 67.5 and 90 degrees. In other words, the rotor 52 is rotated up to 247.5 degrees so that the rotor 41 is rotated 157.5 degrees from the first engaging orifice 431 of the first rotary zone 43 to the third engaging orifice 413 via the second, the third, and the fourth engaging orifices 432, 433, 434 of the first rotary zone 43 and the first and the second engaging orifices 441, 412 of the second rotary zone 44 as shown in Fig. 11 to generate four single and three double watering modes, such as bubbled, jetted, massaged, linear, massaged and bubbled, bubbled and jetted, and jetted and linear watering modes.
From above descriptions, the rotor 52 is rotated at least more than 292.5 degrees and up to 360 degrees so that the levering pin 41 is positioned randomly in the engaging orifices of the first and the second rotary zones 43, 44 to obtain four single and four double watering modes, such as bubbled, jetted, massaged, linear, massaged and bubbled, bubbled and jetted, jetted and linear, linear and massaged watering modes. Of course, the rotor 52 is removed directly without removing any stator as well to obtain aforesaid eight watering modes.
The watering feeding pipe 60 is in communication with the outflow side of the holder 10 to guide water into the passage 11 of the holder 10.
The housing 70 includes a grip portion 71 and a casing 72 extending from a distal end of the grip portion 71 to receive the holder 10, the distributing set 20, and the water feeding pipe 60. The casing 72 includes a pillar 721 fixed on an inner wall thereof to be removably inserted from the axial notch 14 of the holder 10, and includes a number of retaining recesses 722 attached on the inner wall thereof to retain a plurality of hooks 16 of the holder 10.
The rotating ring 80 is movably fitted to the housing 70 and fixed around the distributing set 20 so as to be driven to actuate the distributing set 20 to rotate in relation to the holder 10.

When the rotor is limited between the first and the second stators 531, 532, two watering modes are achieved. When the second stator 532 is removed, three watering modes are generated. Likewise, as the second, the third, the fourth, the fifth, the sixth, and the seventh stators 532, 533, 534, 535, 536, and 537 are removed or all of the stators are removed or only the rotor 52 is removed, eight watering modes are obtained.

The rotable positioning structure 401 includes a first receiving groove 45 and a second receiving groove 46 disposed on an outer rim of the outflow side of the holder 10 to receive the compression spring 411 and the levering pin 41 in one of the first and the second receiving grooves 45, 46. The ten engaging orifices are divided into two rotary zones, e.g., a first rotary zone 47 and a second rotary zone 48, wherein the first rotary zone 47 includes a first, a second, and a third engaging orifices 471, 472, and 473, wherein between any two adjacent engaging orifices is formed a 45 degree of first angle.

The two plugs 30 are used to urge water to flow into the inlets 211 increasingly, enhancing watering efficiency. For example, in double watering mode, due to the opening 31 of the plug 30 is in communication with two inlets 211 so that one half or one part of the inlet 211 is included in the opening 31, therefore as an included area of the inlet 211 becomes more and more, the watering efficiency is increased. As shown in Fig. 18, the opening 31 is formed in an elongated arc shape and the shape of the inlet 211 is in relation to that of the opening 31.
The module core unit 2 is assembled to various spray heads with different watering levels to satisfy different demands, thus lowering mold, maintenance, and related parts costs.
The module spray head of the present invention is assembled by selecting the installing position of levering pin and removing specific stator or rotor, thus assembling easily and quickly.
The two plugs 30 are used to urge water to increase stability between the holder 10 and the distributing set 20 to prevent from slanted swing, thereby having stable watering flow. Also, different watering levels of the module spray head are achieved to meet any demand.

The plugs 30 are disposed to the slots 12 of the holder 10, and each has an opening 31 formed therein and a compression spring 32 to abut against the upper disc 21 of the distributing set 20. When the upper disc 21 rotates relative to the holder 10, the opening 31 of the plug 30 communicates with one set of the inlet 211 of the upper disc 21 to guide water from the passage 11 of the holder 10 to the inlet 211 to spray water flower in a predetermined mode, such as bubbled, jetted, massaged, and linear watering mode. It is to be noted that the plug 30 allows to communicate with two sets of inlets 211 so that water from the passage 11 of the holder 10 is guided to the two sets of inlets 211, generating water flower in double watering mode, such as massaged and bubbled, bubbled and jetted, jetted and linear, and linear and massaged watering mode.
With reference to Figs. 2 and 3, the rotable positioning structure 40 includes a levering pin 41, a compression spring 411, a receiving groove 42, and a plurality of engaging orifices. The receiving groove 42 is disposed on the outflow side of a bottom surface of the holder 10 to receive the compression spring 411 and the levering pin 41 pushed by the compression spring 411; the engaging orifices are located at the concentric point of the inlets 211 to be retained by the levering pin 41, wherein the upper disc 21 includes eight engaging orifices to be divided into two areas, one area is a first rotary zone 43 and a second rotary zone 44 as shown in Fig.
7; the first rotary zone 43 includes four engaging orifices, e.g., a first, a second, a third, and a fourth engaging orifices 431, 432, 433, 434; the second rotary zone 44 includes four engaging orifices, e.g., a first, a second, a third, and a fourth engaging orifices 441, 442, 443, 444; between any two adjacent engaging orifices in the first and the second rotary zones 43, 44 is formed a 45 degree of first angle, and between the fourth and the first engaging orifices 434, 441 is formed a 22.5 degree of second angle.
The angle between the two adjacent engaging orifices of the first rotary zone 43 is equal to that between anyone set of inlet 221 so that as the levering pin 41 displaces from anyone engaging orifice of the first rotary zone 43 to another adjacent engaging orifice, the openings 31 of the plugs 30 of the holder 10 displace from one set of inlet 211 of the upper disc 21 to another set of inlet 211 adjacent to the one set of inlet 211 of the upper disc 21. In other words, as the levering pin 41 abuts against the first, the second, the third, the fourth engaging orifices 431, 432, 433, 434 of the first rotary zone 43 in order, the openings 31 of the plugs 30 communicate with the four sets of inlets 211 of the upper disc 21, generating water flower in the bubbled, jetted, massaged, and linear watering mode.
The angle between the fourth engaging orifice 434 of the first rotary zone 43 and the first engaging orifice 441 of the second rotary zone 44 is designed to 22.5 degrees so that as the levering pin 41 rotates from the fourth engaging orifice 434 to the first engaging orifice 441, the openings 31 of the plugs 30 of the holder rotates from one set of inlet 221 of the upper disc 21 to the two sets of inlets 211.
Besides, the angle between any two adjacent engaging orifices of the second rotary zone 44 is 45 degrees, therefore when the levering pin 41 contacts with the first, the second, the third, and the fourth engaging orifices 441, 442, 443, 444 of the second rotary zone 44, the openings 31 of the plugs 30 communicate with the two sets of inlets 221 to spray water flower in massaged and bubbled, bubbled and jetted, jetted and linear, linear and massaged double watering mode. Accordingly, the first and the second rotary zones 43, 44 are designed based on the number of the watering mode.
For example, as the levering pin 41 is located at any engaging orifice of the first rotary zone, only one watering mode is obtained, however, as the levering pin 41 is located at any one engaging orifice of the second rotary zone 44, a double watering mode is achieved.
The adjustable levering assembly 50 includes four fixing projections radially extending from an peripheral side of the holder 10, and a rotor 52 extending upward form a top surface of the upper disc 21 of the distributing set 20; the fixing projections are a first, a second, a third, and a fourth stators 511, 512, 513, 514, and an angle between the first and the second stators 511, 512 is 90 degrees, an angle between the second and the third stators 512, 513 is 67.5 degrees, an angle between the third and the fourth stators is 90 degrees.
As shown in Fig. 12, before the assembly of the distributing set 20 and the holder 10, the rotor 52 is limited between the first and the second stators 511, 512 to rotate so that as the rotor 52 is biased against the first stator 511, the levering pin 41 of the rotable positioning structure 40 abuts against the first engaging orifice 431 of the first rotary zone 43, hence when the rotor 52 rotates 90 degrees from the first stator 511 toward the second stator 512, the levering pin 41 rotates from the first engaging orifice 431 to the third engaging orifice 433 via the second engaging orifice 432 as illustrated in Fig. 11 to achieve three single watering modes, e.g., bubbled, jetted, and massaged watering mode.
Referring further to Fig. 13, before the assembly of the distributing set 20 and the holder 10, the second stator 512 is manually removed or cut by tool in advance.
Thereafter, the rotor 52 is additionally rotated 67.5 degrees to be up to 157.5 degrees so that a rotor 41 is rotated 157.5 degrees from the first engaging orifice 431 of the first rotary zone 43 to pass through the second, the third, and the fourth engaging orifices 432, 433, 434 toward the first engaging orifice 441 of the second rotary zone 44 as illustrated in Fig. 11 to generate four single and one double watering modes, such as bubbled, jetted, massaged, linear, and massaged and bubbled watering modes.
With reference to Fig. 14, before the assembly of the distributing set 20 and the holder 10, the second and the third stators 512, 513 are removed so that the rotor 52 is additionally rotated 67.5 and 90 degrees. In other words, the rotor 52 is rotated up to 247.5 degrees so that the rotor 41 is rotated 157.5 degrees from the first engaging orifice 431 of the first rotary zone 43 to the third engaging orifice 413 via the second, the third, and the fourth engaging orifices 432, 433, 434 of the first rotary zone 43 and the first and the second engaging orifices 441, 412 of the second rotary zone 44 as shown in Fig. 11 to generate four single and three double watering modes, such as bubbled, jetted, massaged, linear, massaged and bubbled, bubbled and jetted, and jetted and linear watering modes.
From above descriptions, the rotor 52 is rotated at least more than 292.5 degrees and up to 360 degrees so that the levering pin 41 is positioned randomly in the engaging orifices of the first and the second rotary zones 43, 44 to obtain four single and four double watering modes, such as bubbled, jetted, massaged, linear, massaged and bubbled, bubbled and jetted, jetted and linear, linear and massaged watering modes. Of course, the rotor 52 is removed directly without removing any stator as well to obtain aforesaid eight watering modes.
The watering feeding pipe 60 is in communication with the outflow side of the holder 10 to guide water into the passage 11 of the holder 10.
The housing 70 includes a grip portion 71 and a casing 72 extending from a distal end of the grip portion 71 to receive the holder 10, the distributing set 20, and the water feeding pipe 60. The casing 72 includes a pillar 721 fixed on an inner wall thereof to be removably inserted from the axial notch 14 of the holder 10, and includes a number of retaining recesses 722 attached on the inner wall thereof to retain a plurality of hooks 16 of the holder 10.
The rotating ring 80 is movably fitted to the housing 70 and fixed around the distributing set 20 so as to be driven to actuate the distributing set 20 to rotate in relation to the holder 10.
