INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a sprinkler design, and more particularly to a sprinkler improvement in which a sprinkler can be automatically yawed, and is suitable for use in gardening sprinkling. [Prior Art] The conventional hand-held sprinkler is mainly used to connect with the water pipe, so that the water flows into the inner cavity of the sprinkling water and is sprayed out by the nozzle to perform the watering work, but the size of the sprinkling water is required to be used. Instead of swinging and sprinkling water, the hand-operated swinging spray can achieve the purpose of full spraying. Because it relies entirely on the swing of the hand to spray, it will inevitably cause hand fatigue or even damage. φ such as US. Pat. No., No. 6,702, 206, No. 3, 599, 876, No. 5, 984, 207, No. 6, 425, 538, No. 5, 630, 548. They are all designed to sprinkle water, but the nozzles are fixed structures. SUMMARY OF THE INVENTION The main object of the present invention is to provide a water sprinkler that can automatically yaw the nozzle, because the nozzle can automatically yaw and steer, so it is not necessary to swing and sprinkle repeatedly when using the hand, which can ensure The wrist does not feel sore and discomfort, and has the effect of easy and labor-saving operation. A secondary object of the present invention is to provide a sprinkler that automatically deflects the nozzle, and the sprinkler is provided with a control valve for adjusting the yaw rate of the nozzle. [Embodiment] The structural features and other functions and purposes of the present invention will be described in detail with reference to the accompanying drawings:

DESCRIPTION OF THE INVENTION (3) Third figure), the driven worm wheel 4 1 1 at one end of the worm 4 1 is coupled with the central axis 3 1 of the water wheel 3, and the worm 4 1 is also independent from the other side. The worm wheel 4 2 is engaged, the central shaft 42 1 of the worm wheel 42 is engaged with the crank 5 described below; the crank 5 is sleeved on the central axis 4 2 1 of the wheel 4 2 , and the eccentric shaft 5 1 is embedded Combined with the long nozzle hole 2 2 1 of the nozzle 2 - side extending the pipe arm 2 2 (as shown in the fifth figure); the control valve 6 is a hollow valve body, the inside of which is hollow, and both ends are closed, the control valve 6 is implanted into the lateral receiving hole 14 of the body 1, and the first hole 6 1 and the second hole 6 2 are respectively formed on the valve body, and the first hole 61 corresponds to the return through hole 1 1 2 , and The second hole 6 2 is corresponding to the extension tube arm 2 2 , and the control 0 valve 6 is rotatable and can be rotated; according to the above composition, the water flow is introduced from the external water pipe into the hollow interior cavity 1 1 First, through the water inlet through hole 1 1 1 , the water flow directly impacts the blade portion 3 2 to drive the water wheel 3 to rotate, and then uses the central axis 3 1 of the water wheel 3 to sequentially drive the driven worm wheel 4 1 1 , the worm 4 1 And worm gear 4 2 The eccentric shaft 51 of the crank 5 is moved back and forth in the long slot 221 of the extension pipe arm 22, and the head 2 is caused to generate a reciprocating yaw (as shown in the sixth figure), and the water flow passes through the return through hole 1 1 2 It is ejected from the sprinkling hole 2 1 of the head 2. The above-mentioned control valve 6 is mainly used to control the flow rate of the return through hole 1 1 2 . When it is in the fully open state (as shown in the seventh figure), the water flows from the inlet through hole 1 1 1 into the return through hole 1 1 2 The flow rate is the largest, so the water flow can completely enter the hollow inner cavity 1 1 at this time, so the yaw steering action of the nozzle 2 at this time is the fastest, but when the control valve 6 is slightly turned by an angle, due to the return flow The hole 112 is partially open, so the backflow of the water flow will hinder the deviation.
第7頁 1258394 五、發明說明（4) 擺轉向速度將會隨之變為緩慢；若控制閥6為全閉狀態時 (如第八圖），因水流無法自進水通孔1 1 1 進入回流通孔 112 ，故中空内腔1 1的水流流動量呈靜止，此時喷頭2的 偏擺轉向動作也會呈靜止狀態，而此時由連接孔1 2 1 所供 給的水流，即會通過第二孔6 2及回流通孔1 1 2的側孔1 1 3而 從流至喷頭2 。 上述實施例所揭，僅係本發明主要技術之例舉說明， 其並非用以限定本案技術範圍，舉凡涉及等效應用或基於 前項技術手段所為簡易變更或置換者，均應視為屬於本案 技術範圍，例如上述利用蝸桿4 1與蝸輪4 2所組成之減速裝 φ置，其同理亦可任意等效置換。 綜上所述，誠可見本發明所為「喷頭可自動偏擺轉向 .的灑水搶」設計，其整體組成形態於申請前並未見有相同 應用，實屬前所未見之首創改良，且功效確實，已符合新 •穎進步要件無訛，為此依法申請，懇祈 依法賜准發明專 利。實感德便。Page 7 1258394 V. Invention description (4) The swinging speed of the pendulum will become slow; if the control valve 6 is fully closed (as shown in the eighth figure), the water flow cannot enter the water through hole 1 1 1 Returning to the flow hole 112, the flow of the water in the hollow inner chamber 11 is still, and the yaw steering action of the nozzle 2 is also in a static state, and the water flow supplied from the connection hole 1 2 1 will be It flows from the second hole 6 2 and the side hole 1 1 3 of the return through hole 1 1 2 to the shower head 2 . The above embodiments are merely illustrative of the main techniques of the present invention, and are not intended to limit the technical scope of the present invention. Any reference to equivalent applications or simple changes or replacements based on the prior art means should be considered as belonging to the present technology. For example, the above-described speed reduction device φ composed of the worm 4 1 and the worm wheel 4 2 may be used in the same manner, and the equivalent displacement may be arbitrarily equivalent. In summary, it can be seen that the present invention is designed as a "sprinkler that can automatically yaw the nozzle." The overall composition of the model has not been seen before the application, and it is a first-ever improvement that has never been seen before. And the effect is indeed, has been in line with the new Ying Ying progress elements, for this purpose, according to law, pray for legal patents. Real sense of virtue.
