The mechanism is simple in structure and the decontamination process is automatic without resorting to manipulation. In addition, the mechanism being located in the shower head, the appearance is not affected. After using the shower head, the decontamination needles on the moving plate can once again seal the water outlet holes in the plate so that the water flowing out of the shower head can be quickly stopped. shower. 2.

The front end of each of the arms 7 has the a forked head 71, which has two opposite pivots 72 on an inner side thereof to allow each arm 7 to be movably connected to the movable plate 6. The rear end of each of the arms 7 has the form of a flat structure for being in contact and cooperating with the driving element 2. Preferably, the thrust frame 4 is composed of four arms 7. In a practical application, other numbers of arms 7, for example: two arms, three arms, five arms and so on, can be used to form the push frame 4 so as to achieve the object of the present invention.

As illustrated in FIG. 3, each of the guide tubes 61 defines two opposite holes 62 for receiving the two opposite pivots 72 disposed on the forked head 71 of one of the arms 7, so that the arms 7 can be pivotally and movably connected to the movable plate 6.

More specifically, as illustrated in FIG. 4, the upper portion of the driving member 2 comprises an upper central shaft 210, and the lower portion of the driving member 2 comprises a main body 20 and a shaft. central lower 211. As illustrated, the upper central shaft 210 and the lower central shaft 211 constitute the central shaft 21. The upper central shaft 210 defines a central hole 212. The lower central shaft 211 may be equipped with the first central shaft 211. 3. The main body 20 can be placed in contact with the rear ends of the arms 7.

As illustrated in FIG. 5, the fixed plate 1 is provided in its lower part with a central guide shaft 12 movably inserted into the central hole 212 of the upper central shaft 211, and is provided on the lower side of a plurality of pairs of pivot supports 14. Each pair of pivot supports defines a receiving space 13 between them and two holes 15 for respectively receiving the two opposite pivots 70 provided on each of the arms 7.

As illustrated in FIGS. 6 and 7, the air supercharging mechanism 8 comprises a water ejection element 80 and a conical shell 81. The water ejection element 80 is composed of a a water inflow zone 82 and an air inlet zone 83 extending downward from a peripheral wall of the water inlet zone 82 and separated from the inlet zone water 82 by a bottom having a plurality of protuberances each defining a water inlet port 84. The water inlet zone 82 is generally cylindrical. The air inlet zone 83 is generally cylindrical and has an outer diameter smaller than that of the water inlet zone 82. The air inlet zone 83 defines a plurality of inlet openings of Air 85. The conical shell 81 is generally installed around the air inlet area 83. Preferably, eight air inlets 85 are defined in the air inlet area 83. Nevertheless, , other numbers of air inlets, for example: two, three ..., nine and so on, can be defined in the air inlet area 83, to achieve the purpose of the air boosting mechanism.

The number of through holes 100 of the water introduction chamber 10 is identical to the number of water inlet openings 84 of the water ejection element 80 of the air supercharging mechanism 8, and the through holes 100 are aligned with the water inlet ports 84.

Figure 7 illustrates a shower head according to one embodiment of the present invention, which comprises a front cover 90, a plate 91 disposed on the front cover 90, and a rear cover 92. In particular, the shower head comprises in addition to a sealing and decontamination mechanism as mentioned above, between the plate 91 and the rear cover 92.

Also, the shower head further includes a rotary mechanism 93, which includes a threaded cap 930, a sealing cap 931, a hollow spherical head 932, and an O-ring 933. The O-ring 933, the hollow spherical head 932, and the sealing cap 931 are successively mounted in the water introduction chamber 10 of the fixed plate 1. The fixed plate 1 has an external thread on a peripheral wall located on it which defines the introduction chamber 10 to a threaded engagement with the threaded cap 930. The sealing cap 931 seals a gap between the peripheral wall of the water introduction chamber 10 and the hollow spherical head 932.

Referring to Figures 8 and 9, when the shower head is not used, the first spring 3 and the second springs 5 are compressed in small amounts, wherein the drive member 2 can be pressed against the plate fixed 1 by the first spring 3, and the movable plate 6 can be pressed against the plate 91 disposed on the front cover 90 by the second springs 5, and the decontamination needles 60 can extend outside the outlet orifices water of the plate 91.

When the shower head is used, water can enter the water ejection element 80 through the hollow spherical head 932 and can then pass through the water inlet ports 84 of the element to form a high velocity water flow, so that a negative pressure occurs at the gap between the bottom of the water ejection element 80 and the fixed plate 1, and therefore the envelope conical 81 may be deformed to allow air to flow through the air inlets 85 to mix with the flow of water, thereby forming a flow of water pressurized by air. The water pressurized by the air, which is ejected out of the water introduction chamber 10, can force the driving element to move downwards and to compress the first spring 3. Therefore, the the rear ends of the arms 7 can be driven by the driving element 2 to move downwards, so that the arms 7 can rotate about the pivots 70 respectively, and therefore the forked heads 71 of the arms 7 can move up. As the arms 7 are arranged radially, and the rear ends of the arms are located at a common center, the driving member 2 can press the rear ends of the arms 7 simultaneously. In other words, the central part of the push frame 4 can be moved down; while the peripheral portion of the push frame 4 can be moved upwards.

As the forked heads 71 of the arms 7 are movably connected to the movable plate 6, the upward movement of the peripheral part of the push frame 4 can cause the movable plate 6 to move upwards, which in turn forces the second springs 5 in the compression state. Therefore, the decontamination needles 60 can be moved upward to disengage from the water outlet orifices of the plate 91 disposed on the front cover 90, and therefore the shower head can provide a water jet to an user.

Once a bath or shower is finished, the water no longer enters the shower head and therefore the water pressure applied to the driving element 2 disappears. As a result, the first spring 3 can return to its previous state and can therefore force the driving member 2 to move upwards, and the rear ends of the arms 7 (for example, the central portion of the frame). push 4) can therefore be moved upwards while the forked heads 71 of the arms 7 can be moved down. On the other hand, each of the second springs 5 can return to its previous state and therefore help the movable plate 6 to move downwardly to contact the plate 91 disposed on the front cover 90, so that the Decontamination needles 60 can be inserted again through the water outlet holes of the plate 91. Therefore, the water remaining in the shower head can not pass through the water outlet orifices of the plate 91, so as to quickly stop the water flowing outside the shower head.

Whenever a user uses the shower head, the decontamination needles 60 of the movable plate 6 may be forced to retract water outlet orifices of the plate 91 disposed on the front cover 90. Once finished the shower, the decontamination needles 60 may be forced to fit through the water outlet holes of the plate 91. The movement of the decontamination needles 60 during each use of the shower head can automatically remove the accumulated dirt in the outlet openings of the plate 91.

It is noted that when the shower head is not used, as the driving element 2 is moved upwards by the first spring 3, the water above the driving element 2 is pushed by the element to enter the gap between the water ejection element 80 and the fixed plate 1, and then pass through the air inlet ports 85 to reach the deformed conical shell 81 , so that the peripheral wall of the conical casing 81 can be pressed again against the peripheral wall of the fixed plate 1. Therefore, the water contained in the shower head can not flow outside through the air inlets 85 of the water ejection element 80.

Although the present invention has been described with a certain degree of peculiarity, it is understood that the present description is given by way of example only, and that the combination and arrangement of the parts can change without departing of the scope of the invention.
