Anti-scalding faucet structure

This creation is about a faucet structure, especially an anti-scalding faucet structure.

According to the conventional faucet structure, the "switch structure of the faucet" issued by the Department of Public Administration on December 1, 2015, which includes the rotary joint, the positioning bolt assembly, the pivot shaft assembly and the outer cover. Wherein one end of the rotary joint is provided with a movable recess for the sleeve to be set on the faucet seat, and a hole is formed in the movable recess, and the other end of the rotary joint is provided with a joint portion, and a central shaft tube passes through the movable recess and the The locating portion of the central shaft tube is configured to be engaged with the water control valve core of the faucet seat. The positioning bolt assembly comprises a positioning bolt, an elastic member and a lock bolt, and is sequentially accommodated in the hole. And extending the tail of the positioning bolt through the hole, the external part of the bolt is provided with an external thread, so that one end of the elastic member is held on the head thereof, and the other end of the elastic member is screwed into the hole of the bolt a top portion, the positioning post is held to protrude toward the faucet seat, and is engaged in a positioning vacant slot on the faucet seat; the pivot shaft assembly passes through a central shaft tube of the rotating pedestal to rotate the socket and the water control valve Core assembly; the outer cover is connected to the assembly of the rotary joint In summary, when the faucet is in a normal state, the locating pin disposed on the rotating pedestal is often held in the positioning vacant slot of the faucet seat, so that the rotating pedestal cannot be arbitrarily rotated. The water control valve core can not be rotated and can not produce water discharge action, avoiding accidentally touching the switch to discharge water, preventing water dragon The head may cause scald due to the hot water flowing out due to the accidental touch switch; conversely, when the user wants to pluck the water, the user grasps the outer cover and pulls outward toward the axial direction, so that the group is set on the rotating joint. The positioning bolt is followed by the reverse displacement and is disengaged from the positioning slot on the faucet seat to release the restriction on the rotating socket. At this time, the rotating socket can be rotated, and thus the water control spool is rotated to achieve the control. The water control spool adjusts its action of controlling the water discharge.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reason is as follows: According to the conventional structure, in the general state, the positioning pin is set on the rotating socket. The locking state is formed in the positioning notch that is caught in the faucet seat, so that the rotating socket cannot be arbitrarily rotated, and although the false contact can be prevented, the hot water flows out and the scald is suspected, but the cold water is also closed. The closed state causes inconvenience in use, and when the user pulls out the locked seat and unlocks it, but cannot clearly know the direction of the cold and hot water, it is easy to rotate the rotation without ambiguity. When the seat is opened, the hot water is turned on, which causes the user to cause burns in an unexpected situation and lacks safety.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.
