Field of the Invention The invention relates to a water-saving oxygenic spa structure, more 5 particularly, a water-saving oxygenic spa structure that makes the showering process save water, more convenient to use, able to generate oxygenic anion (negatively-charged ion), and be able to control and change the modes of water flow. 2. Description of the Prior Art 10 The showerhead of the prior art merely let the water-flow pass, diffuse and spray out uniformly to facilitate showering or rinsing. However, since the cold and hot water-flow and the amount of water need to be controlled by the faucet, it has the following demerits when it comes to use: 15 (a) One needs to bend his/her body and moves around to turn the faucet for adjusting the temperature and amount of water-flow during the showering; (b) When one finishes showering and intends to shut off the water-flow, there is a time gap that one is unable to shut off the faucet soon 20 enough and results in wasting of water, this accounts for the majority of the water wasted. SUMMARY OF THE INVENTION In light of the above-mentioned demerits of the water-flow control mechanism of the showerhead of the prior art, the invention aims to 25 ameliorate at least some of the disadvantages of the prior art or to 2 provide a useful alternative. The primary objective of the invention is to provide a water-saving oxygenic spa structure that utilizes the pressing-handle that is pivotally connected to the main body to press a control rod and drive an L-shaped 5 pressing plate, and thus forming a lever action to push the push rod of the third control portion which generates a reciprocal catching action, and a button plug is connected to the front end of the push rod for controlling the water-flow channel, consequently, by making use of the pressing-handle on the main body, one is able to freely control the open 10 and close state of the water-flow, thereby achieve the efficacy of being convenient to use during the shower. Another objective of the invention is to provide a water-saving oxygenic spa structure that allows one to be able to shut off the water-flow through the pressing-handle without moving around to turn 15 off the faucet when he/she intends to stop the water-flow. One other objective of the invention is to provide a water-saving oxygenic spa structure that one is able to adjust the water temperature beforehand and use the preset water temperature without re-adjust the water temperature when he/she re-open the water-flow after a temporary 20 shut off, thereby, the invention is able to achieve the efficiency of being convenient to use. A further objective of the invention is to provide a water-saving oxygenic spa structure that the internal portion of the control sleeve barrel appears slant conical surface for catching the slant-face control 25 plates of the control head, consequently, by turning the control sleeve barrel to let it generate displacement and change the relative position between the slant-face control plates and the prop-up barrel, thereby to make the cross-sectional shape and area of the water flow generate continuously varying mode of water spray. To achieve the above-mentioned objective, the invention provides a 5 water-saving oxygenic spa structure that includes at least a main body, a first control portion, a second control portion, and a third control portion where the first control portion is provided at the front end of the main body. By making use of the pressing-handle of the second control portion to press the push rod, which is capable of locking at two 10 positions, for driving the button plug positioned at the water inlet so as to control the open and close state of the shower head. Moreover, the control sleeve barrel is capable of moving back and forth on the control seat. The variation of the relative position between slant-face control plates and the prop-up barrel is capable of changing the shape of the 15 cross-section of the water-outlet channel to achieve the efficacies of saving water, convenience in usage, controlling and varying the modes of water-flow.

The push rod (41) has a two-step diameter-diminishing rod (411) at one end, and a relatively larger diameter end with a screw hole (413) at the other end, as well as a flange (412) at the center portion thereof. The upper pluck rod (43) has a 15 bearing face (431) at an end and a concave hole (430) provided at the other end. The middle pluck rod (42) having an axial penetration hole (420) at its center has axially extended salient teeth (421) provided at its perimeter at an end and has another end fit to the concave hole (430) of the upper pluck rod (43). The axially extended teeth (421) have a slant 20 edge (4221) at the top thereof and a transverse salient block (422) extended from the external side thereof. Axially extended salient teeth (421) are provided at the perimeter of the concave hole (430), and axially extended transverse blocks (433) are provided at the outer side of the axially extended transverse blocks (433). A couple of double salient 25 teeth (451) being flat at their top surface are provided at the interior surface of the sleeve (45) at an end thereof while a hole (450) is provided at the other end thereof. The double salient tooth (451) has a long slant tooth edge (4512), a short slant tooth edge (4513), and an inter-tooth sliding channel (4511) at an end thereof. The inter-tooth sliding channel (4511) has a check portion (4514) at an end thereof. The connecting head (46) has a water inlet (460) at an end and a thread (461) 5 near the other end. The water-sealing ring (44) is placed between the main body (1) and the connecting head (46). The two-step diameter-diminishing rod (411) of the push rod (41) is provided in corresponding to the axial penetration hole (420). A spring (452) is provided within the sleeve (45), and the push rod (41) stretches out 10 through the hole (450) after being slipped on the spring (452). Afterwards, the connecting head (46) is placed into the sleeve (45), and the button plug (47) and the screw hole (413) of the push rod (41) are tied up by employing the screw (48) and disposed at the water inlet (460) of the connecting head (46). In addition, the connecting head (46), after 15 having the water-sealing ring (44) slip on, the thread (461) thereof is made to mesh with the corresponding internal thread (131) of the main body (1). As shown in FIG. 2, when it comes to assembling, the positioning seat (21) of the first control portion (2) is placed into the front end (11) 20 of the main body (1). The control head (23) is attached to the corresponding prop-up barrel (24) and control sleeve barrel (26) sequentially, then the control seat (22) is mounted to the outer edge of the securing seat (111) and is secured by the screw (25). At this moment, the internal thread (261) of the control sleeve barrel (26) 25 meshes with the external thread (222) on the control seat (22). Afterwards, the lid (27) is capped to the top of the prop-up barrel (24). As shown in FIG. 2 again, the control rod (32) of the second control a portion (3) after being slipped on the spring (33) and the water-sealed washers (34) is connected to the sleeve (35), and after being slipped on another water-sealed washers (36) is placed in the through channel (14) stretching through the water-transporting channel (13). The pressing 5 plate seat (38) is pivotally connected to the L-shaped pressing plate (37) making the pressing fitted face (371), which appears as a flat surface, of the L-shaped pressing plate (37) exactly touch the contacting end (321) of the control rod (32) that stretches into the water-transporting channel (13) through the through channel (14). 10 As shown in FIG. 2, and FIG. 3, another prop-up end (372) touches the bearing face (431) at the top end of the upper pluck rod (43) of the third control portion (4). The middle pluck rod (42) is inserted into the hole (450) making the axially extended salient teeth (421) of the middle pluck rod (42) meshes with the axially extended salient teeth (432) of the 15 upper pluck rod (43). The two-step diameter-diminishing rod (411) of the push rod (41) is inserted into the hole (420) of the middle pluck rod (42) making the combination of the push rod (41), middle pluck rod (42), and the upper pluck rod (43) place into the sleeve (45) as well as making the axially extended transverse blocks (433) of the upper pluck rod (43) 20 mesh with inter-tooth sliding channel (4511). What is more, the distal end of the push rod (41) stretches out through the hole (450) of the sleeve (45). Afterwards, the structure of the invention is assembled by engaging the thread (461) of the connecting head (46) with the internal thread (131) of the main body (1) after employing the screw (25) to tie up 25 the button plug (47) at the water inlet (460) at an end of the connecting head (46). FIG. 4 is a flow variation schematic diagram (I) of the invention 10 while FIG. 5 is a flow variation schematic diagram (II) of the invention. As shown in FIG. 4 and FIG. 5, as the water-flow passes from the water-transporting channel (13) through the water outlet (221), (231) and the outer wall edge of the prop-up barrel (24), the water sprays out by 5 making use of the clearance (233) of the slant-face control plates (232), prop-up barrel (24). If the control sleeve barrel (26) is turned to generate relative displacement with respect to the control seat (22), the slant conical surface (260) in the control sleeve barrel (26) is capable of controlling the slant-face control plates (232) making the front end of the 10 slant-face control plates (232) concentrate or diffuse toward the washer (241). In this way, the clearance (233) between the control sleeve barrel (26) and the slant-face control plates (232) as well as the relative position between the washers (241) and the magnitude of the clearance will be changed making the cross-sectional shape and area of the water-flow 15 spray out generate continual variation, thereby obtain water-flow of various modes. FIG. 6 is a cross-sectional view of the closed state action of the water flow of the invention; FIG. 7 is a cross-sectional view of the pressed state action of the invention; while FIG. 8 is a cross-sectional 20 view of the water supplied state action of the invention. As shown in FIG. 6, FIG. 7, and FIG. 8, when it comes to usage, one grasps the pressing-handle (31) to push the control rod (32) so as to drive the L-shaped pressing plate (37) and push the pressing fitted face (371) to turn. It then makes prop-up end (372) of the other end of the L-shaped 25 pressing plate (37) press the bearing face (431) of the upper pluck rod (43). The button plug (47) at an end of the push rod (41) is capable of separating from a step in the water inlet (460) of the connecting head (46) 11 as the push rod (41) is subjected to the mutually meshing interaction among the upper pluck rod (43), middle pluck rod (42), and the double salient teeth (451) in the sleeve (45). Therefore, the water-flow is capable of entering the water-transporting channel (13) of the main body 5 (1) through the hole (450) and the water entering clearance formed within the sleeve (45). FIG. 9 is an action schematic diagram (I) of the outer plucking rod and the central plucking rod within the sleeve barrel of the invention; FIG. 10 is an action schematic diagram (II) of the outer plucking rod and 10 the central plucking rod within the sleeve barrel of the invention; FIG. 11 is an action schematic diagram (III) of the outer plucking rod and the central plucking rod within the sleeve barrel of the invention; while FIG. 12 is an action schematic diagram (IV) of the outer plucking rod and the central plucking rod within the sleeve barrel of the invention. As 15 shown in FIG. 9, FIG. 10, FIG. 11, and FIG. 12, as well as FIG. 2 and FIG. 3, the initial state is shown in FIG. 9. At this moment, the transverse salient block (422) of the middle pluck rod (42) positions exactly on the side of the double salient teeth (451) of the sleeve (45), and the axially extended salient teeth (432) of the upper pluck rod (43) 20 and the transverse salient block (421) of the middle pluck rod (42) are in meshing state. When the bearing face (431) of the upper pluck rod (43) presses downward subjected to external force, the axially extended salient teeth (432) pushes the transverse salient block (421) to make the middle pluck rod (42) descend while the axially extended transverse 25 blocks (433) descends within the inter-tooth sliding channel (4511) to guide the upper pluck rod (43) descending vertically. As transverse salient block (422) descends down to the distal end of the double salient teeth (451), the axially extended salient teeth (421) of the middle pluck rod (42) meshes with the axially extended salient teeth (432) of the upper pluck rod (43). Moreover, through the exertion of the slant edge (4221) of the middle pluck rod (42), the transverse salient block (422) 5 slides into the outer portion of the long slant tooth edge (4512) of the double salient teeth (451). At this moment, the axially extended salient teeth (421) and the axially extended salient teeth (432) will appear in meshing state as shown in FIG. 10. As the force on the bearing face (431) of the upper pluck rod (43) is eliminated, the middle pluck rod (42) 10 props up the upper pluck rod (43) subjected to resilient force of the spring (452) slipped on the push rod (41). At this moment, the transverse salient block (422) will slide into the check portion (4514) along the long slant tooth edge (4512) as shown in FIG. 11. When the upper pluck rod (43) is subjected to external force again and pressed 15 downward, the axially extended salient teeth (421) of the middle pluck rod (42) and the axially extended salient teeth (432) of the upper pluck rod (43)still semi-meshes with each other and contacts downward. When the transverse salient block (422) is driven and descended down to separate from the distal end of the check portion (4514), the middle pluck 20 rod (42) makes the transverse salient block (422) slide toward the outer portion of the short slant tooth edge (4513) subjected to the action of the slant edge (4221) of the meshing portion of the axially extended salient teeth (432) of the axially extended salient teeth (421) and upper pluck rod (43). At this moment, the transverse salient block (422), (432) 25 appear total meshing state as shown in FIG. 12. As the force on the bearing face (431) of the upper pluck rod (43) is eliminated, the transverse salient block (422) slides out of the outer portion of the short 13 slant tooth edge (4513) and restores back to the initial state. Through the pressing action of the pressing-handle (31) of the main body (1) to push the control rod (32) and the L-shaped pressing plate (37) and making use of the action of the control rod (32) pushing the 5 L-shaped pressing plate (37) to push the push rod (41), the salient teeth of the upper pluck rod (43) and the middle pluck rod (42) of the invention catches each other. In association with the meshing action of the upper pluck rod (43) and middle pluck rod (42) within the sleeve (45), the push rod (41) and the sleeve (45) forms reciprocal catching action. 10 Moreover, a button plug. (47) is attached to an end of the push rod (41) by fastening through a screw to control the water-flow channel as well as to control the open and closed status. Consequently, the invention is capable of facilitating the user in taking a shower by using the shower head. 15 It will become apparent to those people skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention.
