As shown in fig. 8, the outer cylindrical surface of the cylindrical block a18 is provided with a ring groove C26 and a ring groove D27, and the ring groove C26 and the ring groove D27 are distributed on the upper and lower sides of the ring groove B24; as shown in fig. 3 and 4, the ring groove C26 and the ring groove D27 are both provided with a sealing ring 30 which is in sealing fit with the inner wall of the cylinder 15 so as to prevent water from entering the ring groove B24; as shown in fig. 4 and 11, the cylindrical surface of the sliding plug 31 is provided with a ring groove F34, and the ring groove F34 is closer to the spring C36 than the ring groove E33; the ring groove F34 is provided with a sealing ring 30 which is in sealing fit with the inner wall of the round groove B19 so as to prevent water from entering the round groove B19 to corrode the spring C36.
As shown in fig. 4, a cylindrical block B37 is screwed in a section of internal thread 51 in the inner wall of the circular groove B19, and a circular plate 39 is rotatably fitted on the end face of the cylindrical block B37 opposite to the sliding plug 31; as shown in fig. 4, 9 and 10, a trapezoidal guide ring 40 is mounted on the circular plate 39, and the trapezoidal guide ring 40 rotates in the trapezoidal ring groove 38 on the end face of the cylindrical block B37; the spring C36 has one end connected to the circular plate 39 and the other end connected to the spool 31.
The working process of the invention is as follows: in the initial state, the outer conical surface B32 on the sliding plug 31 is spaced from the inner conical surface A50 of the cone shell 1, the water draining holes 2 on the cone shell 1 are in the open state, and the spring A13, the spring B29 and the spring C36 are all in the pre-compression energy storage state. The four water permeable holes A16 on the cylinder 15 are staggered with and not communicated with the four water permeable holes B23 on the cylinder A18, and the inner wall of the cylinder 15 forms a closed state for the four water permeable holes B23 on the cylinder A18. The conical ring plate B10 is located at the top end limit position in the conical ring plate A7, and the ends of the pins 11 densely distributed on the conical ring plate B10 are hidden in the sliding grooves B8 on the outer conical surface C55 of the conical ring plate A7.
When the multifunctional shower head is used for bathing, tap water is switched on by turning on a switch, the tap water instantly enters the circular groove C20 at the upper end of the cylindrical block A18 through the cylinder 15, the water pressure of the tap water pushes the cylindrical block A18 to vertically move downwards relative to the cylinder 15, the telescopic shaft 41 performs self-adaptive extension under the pulling of the cylindrical block A18, and the cylindrical block A18 drives the sliding plug 31 to synchronously and quickly approach the draining hole 2 at the conical tip of the conical shell 1 through the cylindrical block B37, the circular plate 39 and the spring C36. The spring B29 is further compressed to store energy, and the four water-permeable holes B23 of the cylindrical block a18 are respectively and rapidly close to the four water-permeable holes a16 of the cylinder 15.
When the outer conical surface B32 of the sliding plug 31 meets the inner conical surface a50 of the cone housing 1, the four water-permeable holes B23 of the cylindrical block a18 still do not meet and face the corresponding water-permeable holes a16 of the cylinder 15, respectively. Under the continued push of the water, cylinder block A18 continues to move vertically downward within cylinder 15 and further compresses spring C36, and telescopic shaft 41 continues to extend. The sliding plug 31 moves vertically upwards in the circular groove B19 relative to the cylindrical block A18, and the spring C36 which is further compressed tightly presses the sliding plug 31 against the inner conical surface A50 of the cone shell 1, so that the water draining holes 2 on the cone shell 1 are tightly closed.
When the four water permeable holes B23 on the cylindrical block A18 meet and completely face the four water permeable holes A16 on the cylinder 15 at the same time, the cylindrical block A18 reaches the limit position and stops moving, the spring C36 and the spring B29 are compressed to the limit at the same time, tap water quickly enters and fills the cone shell 1 through the circular groove C20 at the upper end of the cylindrical block A18, the four water permeable holes B23 and the four water permeable holes A16 on the cylinder 15, and water in the cone shell 1 is sprayed downwards through the colloid nozzles 6 arranged in the water spraying holes 3 densely distributed on the inner conical surface A50 of the cone shell 1 under the hydraulic pressure.
When bathing is finished, the switch is turned off to cut off tap water, the water pressure at the end of the circular groove C20 on the cylindrical block A18 is suddenly reduced, the cylindrical block A18 quickly slides upwards and vertically under the reset action of the spring C36 relative to the cylinder 15, the telescopic shaft 41 is pushed by the cylindrical block A18 to retract in a self-adaptive mode, the cylindrical block A18 drives the circular plate 39 to move synchronously through the cylindrical block B37 in threaded fit with the cylindrical block A18, the spring C36 releases energy, and the pressing force of the sliding plug 31 on the inner conical surface A50 of the conical shell 1 is quickly reduced.
When the four water-permeable holes B23 of the cylindrical block a18 are completely staggered with respect to the corresponding water-permeable holes B23 of the cylinder 15, the cylindrical block a18 is stopped from moving without being completely restored by the tap water in the steel water pipe 49 enclosed in the space between the switch and the cylindrical block a18, and the compression amount of the spring B29 is slightly larger than that in its initial state. At this time, the cylindrical block a18 drives the sliding plug 31 to separate from the inner conical surface a50 of the cone shell 1 by the cylindrical block B37, the circular plate 39 and the spring C36 which completely restores the initial compression state, the distance is slightly smaller than that in the initial state, and the draining hole 2 at the cone tip of the cone shell 1 is completely opened. The water in the space between the conical shell 1 and the cylindrical block A18 in the steel water pipe 49 and the water retained in the conical shell 1 are completely discharged through the water draining holes 2 under the action of self weight, so that the residual water in the conical shell 1 is ensured not to remain, and the sediment in the water is prevented from being accumulated on the inner conical surface A50 of the conical shell 1 to cause the blockage of the water sprinkling holes 3.
In the invention, because the sliding plug 31 is in sealed sliding fit with the inner wall of the round groove B19, water cannot enter the round groove B19 to corrode the spring C36. Because the cylinder block A18 and the inner wall of the cylinder 15 are in sealing sliding fit, water cannot enter the ring groove B24 on the outer side of the cylinder block A18 to corrode the spring B29.
When the spring force generated by the compressed spring C36 is not enough to press the sliding plug 31 tightly against the inner conical surface a50 of the cone shell 1 after a period of use, then by manually rotating the torsion wheel 47, the torsion wheel 47 drives the cylindrical block B37 to rotate through the rotating shaft 46, the bevel gear a45, the bevel gear B44 and the telescopic shaft 41, the cylindrical block B37 vertically moves downwards relative to the cylindrical block a18 under the action of the internal thread 51 in threaded fit with the cylindrical block B37 and further compresses the spring C36 through the circular plate 39, so that the pressing force of the spring C36 against the sliding plug 31 is increased. When the compression amount of the spring C36 reaches the requirement, the adjustment of the compression amount of the spring C36 can be completed by stopping rotating the torsion wheel 47.
When the water sprinkling hole 3 on the conical shell 1 is still blocked after the water sprinkling device is used for a long time, the circular ring 14 is pressed manually and reciprocally, the spring A13 nested on the guide rod 12 is compressed and released energy reciprocally, the circular ring 14 drives the conical ring plate B10 to reciprocate vertically in the conical ring plate A7 through the four guide rods 12, the conical ring plate B10 drives the inserting needles 11 densely distributed on the conical ring plate B10 to dredge the colloid nozzle 6 arranged in the water sprinkling hole 3 on the conical shell 1 reciprocally, and the circular ring 14 is stopped being pressed after the water sprinkling hole 3 is dredged, so that the water sprinkling hole 3 on the conical shell 1 can be dredged.
In conclusion, the beneficial effects of the invention are as follows: the sliding plug 31 of the invention completely opens the draining hole 2 at the cone tip of the cone shell 1 when the water spraying is finished, and the water remained in the cone shell 1 and the steel water pipe 49 is completely discharged through the draining hole 2 under the action of the self weight, thereby completely avoiding the blockage of the water spraying hole 3 on the cone shell 1 due to the accumulation of the sediment in the residual water on the inner cone surface A50, avoiding the need of regularly cleaning and dredging the water spraying hole 3 on the cone shell 1 and providing the life convenience. If after long-time use, the water sprinkling holes 3 in the conical shell 1 are blocked due to other reasons, the inserting pins 11 arranged in the conical shell 1 can be driven by the reciprocating pressing ring 14 to integrally insert, clean and dredge the water sprinkling holes 3 in the conical shell 1, so that smoothness and convenience in use of the water sprinkling holes 3 in the conical shell 1 are guaranteed.
