技术领域 technical field
本实用新型属于水龙头设备技术领域，尤其涉及一种基于先导结构的旋转式水龙头。 The utility model belongs to the technical field of faucets, in particular to a rotary faucet based on a pilot structure.
背景技术 Background technique
水龙头作为我们日常生活中使用品，无论是居家还是在公共场所随处可见。最初的水龙头是用青铜浇铸的，后来改用便宜些的黄铜。随着时代转变经济的快速发展，水龙头行业也得到巨大的变革，按材料来分，可分为SUS304不锈钢、铸铁、全塑、黄铜、锌合金材料水龙头，高分子复合材料水龙头等类别。然而按开启方式来分，水龙头又可分为螺旋式、扳手式、抬启式和感应式等。螺旋式手柄打开时，要旋转很多圈；扳手式手柄一般只需旋转90度；抬启式手柄只需往上一抬即可出水；感应式水龙头只要把手伸到水龙头下，便会自动出水。在日常生活中，螺旋式、扳手式、抬启式在使用完毕后都需要再次去手动关闭，不能实现自动关闭水龙头，往往又再次弄脏了双手；虽然感应式水龙头在一定程度上解决了这个问题，但是感应式水龙头往往结构复杂，价格昂贵。随着机械现代化的不断发展，出现了各种新型自动水龙头，其中公共场所中按压式自动水龙头最为常见，只需按压开关便会有水流出，而且使用后可实现自动关闭水龙头，但是使用时按压较为费力，且出水速度较慢。 Faucets are used in our daily life, whether they are at home or in public places. The original taps were cast in bronze, later switched to less expensive brass. With the rapid development of the changing economy, the faucet industry has also undergone tremendous changes. According to the materials, it can be divided into SUS304 stainless steel , cast iron, plastic, brass , zinc alloy faucets, polymer composite faucets and other categories. However, according to the opening method, the faucet can be divided into spiral type, wrench type, lifting type and induction type. When the screw-type handle is opened, it needs to be rotated many times; the wrench-type handle generally only needs to be rotated 90 degrees; In daily life, the spiral type, wrench type, and lifting type all need to be manually closed again after use, and the faucet cannot be automatically closed, and often dirty hands again; although the induction faucet solves this problem to a certain extent Problems, but sensory faucets are often complicated in structure and expensive. With the continuous development of mechanical modernization, various new automatic faucets have appeared, among which push-type automatic faucets are the most common in public places. Just press the switch and water will flow out, and the faucet can be automatically turned off after use. It is more laborious and the water output speed is slower.

实际使用时，首先小活塞杆7上的弹簧挡环在弹簧9的作用力下向下运动，从而小活塞杆7上的小活塞密封圈10压在大活塞11的先导孔上，进而驱使大活塞11在主体盖内腔14内部向下运动，最终大活塞11上的大活塞密封圈12压在密封圆筒16上，从而实现关闭状态；当自来水从主体1右侧的进口13流入，水通过大活塞11与主体盖内腔14之间的间隙进入主体盖内腔14，由于在液动力以及弹簧9的作用力下，先导孔关闭，大活塞11也处于闭合状态，当轻轻旋转转盘6时，转盘6带动小活塞杆7旋转，从而定位销17跟随沿着主体盖4上的斜度坡口斜向上移动，从而将小活塞杆7抬启，小活塞密封圈8与先导孔分离，液体迅速的从先导孔流入密封内腔15，从而流往出口2，由于液体迅速流出，从而造成大活塞11上方主体盖内腔14压强迅速下降，进而大活塞11上下形成压强差，在压差的作用下大活塞11被迅速抬起，从而实现水龙头开启状态；当液体不断通过大活塞11与主体盖内腔14之间的间隙进入主体盖内腔14，主体盖内腔14压强慢慢得到弥补以及弹簧9由于被压缩产生反作用力，进而驱使小活塞杆7向下运动，由于定位销17与主体盖4上的斜度坡口发生滑动摩擦从而产生一定延长时间，进而利于水龙头继续流水，一段时间后小活塞杆7上的小活塞密封圈10压在大活塞11的先导孔上，驱使大活塞11在主体盖内腔14内部再次向下运动，最终大活塞11上的大活塞密封圈12压在密封圆筒16上，从而实现水龙头关闭。 In actual use, first the spring stop ring on the small piston rod 7 moves downward under the force of the spring 9, so that the small piston sealing ring 10 on the small piston rod 7 presses on the pilot hole of the large piston 11, and then drives the large The piston 11 moves downward in the inner cavity 14 of the main body cover, and finally the large piston sealing ring 12 on the large piston 11 presses on the sealing cylinder 16, thereby realizing the closed state; when tap water flows in from the inlet 13 on the right side of the main body 1, the water Enter the body cover cavity 14 through the gap between the large piston 11 and the body cover cavity 14, due to the force of the hydraulic force and the spring 9, the pilot hole is closed, and the large piston 11 is also in a closed state. When the turntable is rotated slightly At 6 o'clock, the turntable 6 drives the small piston rod 7 to rotate, so that the positioning pin 17 moves obliquely upward along the slope groove on the main body cover 4, thereby lifting the small piston rod 7, and the small piston sealing ring 8 is separated from the pilot hole , the liquid quickly flows into the sealed inner cavity 15 from the pilot hole, and then flows to the outlet 2. Due to the rapid flow of the liquid, the pressure in the inner cavity 14 of the main body cover above the large piston 11 drops rapidly, and then a pressure difference is formed between the upper and lower sides of the large piston 11. Under the action of the difference, the large piston 11 is quickly lifted, thereby realizing the open state of the faucet; when the liquid continuously enters the main body cover inner cavity 14 through the gap between the large piston 11 and the main body cover inner cavity 14, the pressure of the main body cover inner cavity 14 gradually increases. It is compensated and the spring 9 generates a reaction force due to being compressed, and then drives the small piston rod 7 to move downward. Since the positioning pin 17 and the slope groove on the main body cover 4 have sliding friction, a certain prolongation time is generated, which is beneficial to the faucet to continue to flow. After a period of time, the small piston sealing ring 10 on the small piston rod 7 presses on the pilot hole of the large piston 11, driving the large piston 11 to move downward again inside the inner cavity 14 of the main body cover, and finally the large piston seal on the large piston 11 The ring 12 presses against the sealing cylinder 16, so that the faucet is closed.
利用本实用新型所述的技术方案，或本领域的技术人员在本实用新型技术方案的启发下，设计出类似的技术方案，而达到上述技术效果的，均是落入本实用新型的保护范围。 Utilize the technical solution described in the utility model, or those skilled in the art design similar technical solutions under the inspiration of the technical solution of the utility model, and achieve the above-mentioned technical effect, all fall into the protection scope of the utility model .
