OBJECTS OF THE INVENTION · Technical Fields of the Invention The present invention relates to a faucet structure, and more particularly to a "water outlet flow switching structure of a faucet that utilizes the elastic force of a pressure release ring to open a release sheet to make the inside of the water head The residual pressure can be discharged from the drainage hole, which can produce the effect of releasing pressure, so that the residual pressure inside the outlet head can be reduced to prevent the residual pressure from being too high to automatically switch. [Previous technique] A faucet switching structure is known as shown in Fig. 7 which includes: a water outlet head (50), a switching valve (60) and a water inlet cover (70), and an outlet head (50) is provided inside. The switching port (51) is provided with a switching valve (60) at the switching port (51). The switching valve (60) is composed of a linkage lever (61), a blocking piece (62), a connecting block (63) and a lever ( 64), the limit groove (611) of the linkage rod (61) is fastened with a buckle (612)' and the linkage rod (61) passes through the connection block (63) and is locked with a blocking piece (62) , the blade (62) is provided with a water stop ring (621) near the switching port (51), and the upper end of the connecting block (63) is connected with a control a rod (64), the control rod (64) is passed through the water outlet (50) and is provided with a water control hole (7) in the center of the water inlet cover (70), and the water inlet cover (7〇) is locked When the water outlet head (50) is formed to cover, and the switching valve (6〇) closes the switching port (51), the water flow can be guided to the head end water outlet, and when the water source is not provided, the water outlet head (50) is inside. The water pressure is lowered. When the water pressure is less than the weight of the switching jaw (6〇), the switching valve (62) can open the switching port (51) by the weight of the body, thereby switching to the position where the water head (50) is discharged. In the next use, the system will not unexpectedly come out from the shower head 201031847. The above-mentioned conventional structure is not difficult to find that there are still some shortcomings, the main reasons are as follows: its switching valve (6〇) is The blocking piece (62) is blocked at the switching port (51) of the water outlet head (50), and the residual pressure is retained in the water outlet head (5〇) when the water supply is stopped after use, and the residual pressure is less than the weight of the switching valve (6〇). When the flap (62) is displaced downward, the switching port (51) is opened, and if the residual pressure inside the outlet head (50) is too high, the switching valve (6〇) is If the law completes the automatic switching operation, there will be any unexpected occurrence of water from the shower head. 'This will cause inconvenience in use. ❹ In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. The target, the detailed design and the prudent evaluation, the invention is finally practical. [Disclosed] The technical problem to be solved: A faucet switching structure is known, and the switching valve is blocked by the damper in the effluent The switching port of the head will have residual pressure in the water head when the water supply is stopped after use. If the residual pressure of the water outlet is too high, the switching valve cannot complete the automatic switching operation, and there will be no expected shower head. The occurrence of water will cause inconvenience in use. Technical feature of solving the problem: a water outlet flow switching structure of a faucet, comprising: a water head-switching valve, a control rod and a water inlet cover, wherein a water outlet is provided with a switching port, and There is a water outlet end and a water inlet chamber at the switching port, and a control rod hole is opened at the upper end of the water outlet end. A switching valve is composed of a linkage rod, a blocking piece, a pressure release ring and a pressure release piece, and the end of the linkage rod is provided with a limit. The groove is fixed at the limit groove, 201031847, and the other end of the linkage rod is formed with a pressure regulating section and a threaded section, and a support groove is opened at the adjustment section, and a stopper is fixed at the groove. The film is locked by the mosquito hole at the threaded section of the linkage rod _ finely defined, and the @定孔向向形财环槽 and a plurality of drainage holes, the pressure relief ring is a flexible ring body, and is set in the broadcast The release pressure ring of the sheet is a sheet with a sliding hole, and is sleeved on the pressure regulating section of the linkage rod, and the _ rod is placed in the hole of the outlet head and is worn. a locking member is provided at the end, and the connecting member has a connecting hole transversely and The connecting hole of the switching hole is connected with the connecting rod of the switching valve, and the water inlet end is formed with a water inlet end, and a water control port with a semicircular opening is opened at the water inlet end, and the water inlet cover is locked. The head enters the water chamber end. The water outlet head is locked at the water supply line at the water inlet end of the water inlet cover, and the water supply pipeline is connected to the shower head for the shower. In the unused state, the flap of the switching valve does not block the switching of the water outlet head. When the water is supplied from the water supply pipeline, the water flow system can flow through the water inlet chamber, the switching port and the water outlet end in sequence to form the water. If the water is to be used, the control unit is pulled upwards, and the upward movement is carried out. The connecting member drives the linkage rod of the switching valve to move upward. At this time, the blocking piece and the pressure releasing month are moved upward to block the switching port of the water outlet head, and the water inlet pressure is used to press the blocking piece and the pressure releasing piece from the water inlet end. The flap is attached to the switching port to form a closed portion, and the pressure releasing sheet is compressed to release the pressure releasing ring to cover the drain hole. Since the switching port of the water outlet head is blocked by the switching valve, the water flow system of the water supply line can be The water is discharged from the head end of the upper end. When the water supply of the water supply line is cut off after use, the water inlet pressure of the water supply line drops and a residual pressure is formed at the water inlet end. When the residual pressure is lower than the elasticity of the pressure release ring, the pressure is released. The ring system is pressed outwards to release the pressure piece A gap is formed between the release film and the 201031847 release plate, and the water flow at the water inlet end is discharged from the drainage hole, that is, the residual pressure at the water inlet end can be reduced, and when the residual pressure is lower than the weight of the switching valve, the flap is displaced downwardly. When it is stopped, it can maintain the state that the switching valve is out of the water at the outlet end. When it is used next time, it will not be unexpectedly discharged from the shower head. Compared with the effect of the prior art: a relief pressure ring is arranged at the flap of the switching valve, and a plurality of drainage holes are opened, and a pressure release piece is arranged on the pressure regulating section end of the linkage rod, and the water pressure is applied to the water inlet end. ® When descending, the elastic force of the pressure release ring can release the pressure release sheet, so that the residual pressure can be released from the gap generated by the pressure release sheet to the drainage hole, and the pressure release ring and the pressure release sheet can be activated. The effect of releasing pressure is generated, so that the residual pressure inside the water head is lowered, and the residual pressure is prevented from being excessively high, and the automatic switching cannot be performed.
