Description

Technical Field

[0001] The invention relates to the field of bathroom faucets, and in particular to a button-linked automatic reset shower mechanism and a shower faucet. Background Art

[0002] Most of the existing shower faucets use a main switch to control the opening and closing of the entire faucet, and switch the function mode through a button. Generally, a shower faucet is provided with three buttons, which respectively control the multi-functional water outlets such as the top spray water outlet, the hand-held shower water outlet, and the bottom water outlet.

[0003] However, the three buttons and the main switch of this shower faucet are all controlled independently. After using the overhead spray or hand-held shower head for showering, even if the main switch is turned off and the overhead spray or hand-held shower head stops discharging water, the function buttons of the overhead spray or hand-held shower head are still turned on. When the shower faucet is used next time and the main switch is turned on, water will flow out of the overhead spray or hand-held shower head. If the user does not react in time, he will be accidentally sprayed, resulting in a poor product experience. Moreover, for some elderly users, being accidentally sprayed by the water sprayed by the overhead spray or hand-held shower head may easily cause dangers such as falling. Summary of the invention

[0052] Specifically, the use process of the present invention is as follows:

[0053] In the original state: the main valve core 3 is pressed by the driving member 6 in the downward pressure state, the mixed water channel is blocked from the cold water inlet channel 11 and the hot water inlet channel 12, the linkage cover 8 and the lower water outlet button module 5a are in the pressed state, the lower water outlet channel is connected, and the first hook 51 of the water outlet button module 5 and the second hook 71 of the linkage rod 7 form a self-locking, while the top spray water outlet button module 5b and the hand shower water outlet button module 5c are in the reset state, and the top spray water outlet channel 22 and the hand shower water outlet channel 23 are blocked by the top spray water outlet button switch valve core 42 and the hand shower water outlet button switch valve core 43 respectively;

[0054] The external drive member 6 is buckled, and the main valve core 3 is opened accordingly, and the water mixing channel is connected with the cold water inlet channel 11 and the hot water inlet channel 12. The cold and hot water in the cold water inlet channel 11 and the hot water inlet channel 12 are mixed in the water mixing channel and flow out through the lower water outlet channel and the lower water outlet faucet;

[0055] The hand-held showerhead water outlet button module 5c is pressed. During the pressing process, the first hook 51 of the hand-held showerhead water outlet button module 5c contacts the second hook 71 of the linkage rod 7, forcing the linkage rod 7 to move toward the end where the second elastic reset member 72 is set, and at the same time compressing the second elastic reset spring member. After reaching a certain stroke, the first hook 51 of the lower water outlet button module 5a is disengaged from the second hook 71 of the linkage rod 7, and the lower water outlet button module 5a is reset under the action of the first elastic reset member 52, and the lower water outlet button module 5a and the linkage rod 7 are released from self-locking, the lower water outlet channel is closed, and the lower water outlet channel stops discharging water; at the same time, the hand-held showerhead water outlet button module 5c is pressed to a certain stroke, and the linkage rod 7 is no longer forced to continue to move toward the end where the second elastic reset member 72 is set. The linkage rod 7 moves in the opposite direction under the action of the second elastic reset member 72, so that the first hook 51 of the hand-held showerhead water outlet button module 5c forms a self-locking with the second hook 71 of the linkage rod 7, and the hand-held showerhead water outlet channel 23 is connected, so that the hand-held showerhead water outlet is realized;

[0056] The top spray water outlet button module 5b is pressed. During the pressing process, the first hook 51 of the top spray water outlet button module 5b contacts the second hook 71 of the linkage rod 7, forcing the linkage rod 7 to move toward the end where the second elastic reset member 72 is set, and at the same time compressing the second elastic reset member 72. After reaching a certain stroke, the first hook 51 of the hand-held shower water outlet button module 5c is disengaged from the second hook 71 of the linkage rod 7, and the hand-held shower water outlet button module 5c is reset under the action of the first elastic reset member 52. The hand-held shower water outlet button module 5c and the linkage rod 7 are released from self-locking, the hand-held shower water outlet channel 23 is closed, and the hand-held shower stops discharging water; at the same time, the top spray water outlet button module 5b is pressed to a certain stroke, and the linkage rod 7 is no longer forced to continue to move toward the end where the second elastic reset member 72 is set. The linkage rod 7 moves in the opposite direction under the action of the second elastic reset member 72, so that the first hook 51 of the top spray water outlet button module 5b and the second hook 71 of the linkage rod 7 form a self-locking, and the top spray water outlet channel 22 is connected, so that the top spray nozzle can discharge water;

[0057] The driving member 6 is pressed down. During the pressing process, the driving member 6 contacts the linkage cover 8 and drives the lower water outlet button module 5a to be pressed down synchronously. The first hook 51 of the lower water outlet button module 5a contacts the second hook 71 of the linkage rod 7, forcing the linkage rod 7 to move leftward and compressing the second elastic reset member 72. After reaching a certain stroke, the first hook 51 of the top water outlet button module 5b is disengaged from the second hook 71 of the linkage rod 7, and the top water outlet button module 5b is reset under the action of the first elastic reset member 52. The top water outlet button module 5b and the linkage rod 7 are released from self-locking, and the top water outlet channel 22 When the shower faucet is closed, the top shower stops discharging water; at the same time, under the downward pressure of the driving member 6, the lower water outlet button module 5a continues to be pressed down to a certain stroke, and no longer forces the linkage rod 7 to move toward the end where the second elastic reset member 72 is set. The linkage rod 7 moves in the opposite direction under the action of the second elastic reset member 72, so that the first hook 51 of the lower water outlet button module 5a and the second hook 71 of the linkage rod 7 form a self-locking, and the lower water outlet channel is connected. At the same time, the driving member 6 is also pressed down into place synchronously, and the main valve core 3 separates the mixing water channel from the cold water inlet channel 11 and the hot water inlet channel 12, and the shower faucet is closed and restored to its original state.

[0058] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
