[0002] The present application relates to the field of bathroom, in particular to a multi-mode double-delay faucet. SUMMARY

[0003] The present application aims to develop a multi-mode delay faucet with simple structure and easy assembly, that is, a faucet that can independently select a delay switch mode or a manual switch mode.

[0004] To achieve the purpose of the present application, a multi-mode double-delay faucet is disclosed, comprising a rotating handle, a rotating shaft connected with the rotating handle, a movable ceramic sheet and a fixed ceramic sheet, a valve core shell wall with at least one drain port, the rotating shaft extending into the valve core shell, driving the movable ceramic sheet and the fixed ceramic sheet to rotate relative to each other to realize the conduction or closure of the waterway, further comprising:

[0005] The rotating handle has a flange plate in the inner cavity, the middle part of the flange plate is provided with a middle hole for passing through the rotating shaft, the edge of the flange plate is provided with a stop table, and the main body of the flange plate is provided with at least one spring limiting buckle around the middle hole;

[0006] A pull rod is inserted into an axial insertion slot in the rotating handle, and the pull rod moves on the main body of the flange plate with the rotation of the rotating handle;

[0007] A circular torsion spring, one end of which is an expanding arc-shaped end, is detachably hooked on the stop table of the flange plate, and the other end of the torsion spring is fixed in the spring limiting buckle; the expanding arc-shaped end is located on the moving track of the pull rod;

[0008] The movable ceramic sheet and the fixed ceramic sheet have a relative position of mutual closure of the waterway, which is called position A, the stop table position of the flange plate corresponds to position A, the fixed ceramic sheet is provided with a first water outlet hole in the left turning direction of the movable ceramic sheet at position A, and a second water outlet hole in the right turning direction of the movable ceramic sheet at position A;

[0009] When the rotating handle drives the rotating shaft to turn left from position A, the movable ceramic sheet turns left, and the pull rod moves leftward at the same time, the pull rod meets the expanding arc-shaped end of the torsion spring at the stop table position, thereby pushing the expanding arc-shaped end away from the stop table and intensifying the deformation of the torsion spring, at this time, the water inlet of the movable ceramic sheet is connected with the first water outlet hole, the rotating shaft stops at the preset position, the expanding arc-shaped end of the torsion spring pushes the pull rod to reset to the stop table to overcome the deformation process, drives the rotating handle to rotate and reset synchronously, drives the rotating shaft to reset, and further drives the movable ceramic sheet to rotate and reset to position A with the fixed ceramic sheet, thereby closing the waterway;

[0010] When the handle is turned right to drive the rotating shaft, the movable ceramic piece is turned right, and the pull rod moves right to separate from the arc-shaped end of the torsion spring. At this time, the handle is continuously turned to drive the water guide of the movable ceramic piece to be connected with the second water outlet.

[0011] Further, the flange body is provided with 3-5 spring limiting buckles around the middle hole, which are used to adaptively adjust the deformation degree of the torsion spring.

[0012] Further, the flange edge is provided with a retaining edge to form an inner recessed stop position, and the arc-shaped end of the torsion spring is detachably hooked on the inner recessed stop position of the retaining edge.

[0013] Further, the pull rod has an outer thread on the rod body, and the axial insertion slot of the rotating handle has a corresponding inner thread on the inner wall. The pull rod is inserted into the axial insertion slot by screwing.

[0014] Further, the rotating handle includes a handle body and a rotating flange. The position of the rotating flange corresponds to the position of the flange retaining edge. The left side of the rotating flange is provided with a delay switch indication mark, and the right side of the rotating flange is provided with a manual switch indication mark. The central axis of the rotating handle is provided with an assembly through hole, and the inner wall of the assembly through hole is provided with a plurality of axial first teeth. The upper end of the rotating shaft is provided with axial second teeth engaged with the axial first teeth. The upper end of the rotating shaft is arranged in the assembly through hole, and the rotating shaft is connected and rotated through the engagement between the teeth.

[0015] Further, the rotating shaft has a rotating block at the lower end. The rotating block is synchronously connected and rotated with the upper rotating shaft and the lower movable ceramic piece. The side wall of the rotating block is provided with an outwardly protruding elastic pin. The position of the elastic pin corresponds to position A. The valve core shell is provided with a limiting hole corresponding to the position A, into which the elastic pin is elastically inserted. When the arc-shaped end of the torsion spring is hooked on the retaining edge, the elastic pin is elastically inserted into the limiting hole of the valve core shell, and a click sound or a click feeling is generated.

[0016] Further, a valve core seat is provided. The valve core seat has a water inlet hole. The valve core seat is fixed to the bottom of the valve core shell. The fixed ceramic piece is further fixed to the valve core seat.

[0017] After adopting the above structure, the product has a delay and a normally open (manual switch) dual mode. The user can select the delay or manual switch mode according to the requirements, so that the product has a wide application scene and a good emergency effect.

[0018] Secondly, reasonable structure design, especially in the water flow not via flange and torsion spring structure, etc., ensures that the influence of water quality and temperature on the delay time is minimal, so that the delay time of the patent is only affected by the interaction between the friction between the ceramic sheets, the O-ring friction and the torsion spring elastic force, and the performance and quality of the torsion spring can be well controlled to ensure the quality stability.

[0019] Thirdly, the instant long-term use will not affect the normal opening and closing function even if the torsion spring is damaged. When the torsion spring is damaged, the product only needs to be switched to the normally open (manual switch) dual mode, which will not affect the use. BRIEF DESCRIPTION OF DRAWINGS
