[0002] The invention relates to the field of sanitary ware, in particular to a multi-mode double-delay faucet. Summary of the invention

[0003] The purpose of the present invention is to develop a time-delay faucet with multiple modes which is simple in structure and easy to assemble, that is, a faucet which can independently select a time-delay switch mode or a manual switch mode.

[0004] To achieve the purpose of the present invention, the present invention discloses a multi-mode dual-delay faucet, comprising a rotating handle, a rotating shaft linked to the rotating handle, a moving ceramic sheet and a fixed ceramic sheet, a valve core housing wall with at least one drain port, the rotating shaft extends into the valve core housing, driving the moving ceramic sheet and the fixed ceramic sheet to rotate relative to each other to realize the conduction or closing of the water path, and further comprising: The inner cavity of the rotating handle has a flange, the middle of the flange is provided with a central hole for passing the rotating shaft, the edge of the flange is provided with a stop platform, and the flange body is provided with at least one spring limit buckle around the central hole; A pull rod, which is inserted into an axial slot in the rotating handle and moves on the flange body as the rotating handle rotates; A circular torsion spring, one end of which is a movable end and is set as an outwardly expanded arc end, the outwardly expanded arc end can be detachably hooked on the stop platform of the flange, and the other end of the torsion spring is fixed in the spring limit buckle; the outwardly expanded arc end is located on the moving track of the pull rod; The movable ceramic plate and the fixed ceramic plate have a relative position where the water channels are mutually closed, which is called position A. The stop position of the flange plate corresponds to position A. The fixed ceramic plate is provided with a first water discharge hole in the left turning direction of the movable ceramic plate at position A, and a second water discharge hole in the right turning direction of position A. When the handle is turned from position A to drive the rotating shaft to turn left, the moving ceramic piece turns left, and the pull rod follows the left movement. The pull rod meets the outward-expanded arc-shaped end of the torsion spring at the stop position, and then pushes the outward-expanded arc-shaped end away from the stop, aggravating the deformation of the torsion spring. At this time, the water guide port of the moving ceramic piece is connected to the first water outlet, and the rotating shaft stops at the preset position. In the process of overcoming the deformation, the outward-expanded arc-shaped end of the torsion spring pushes the pull rod to reset to the stop, driving the rotating handle to rotate and reset synchronously, driving the rotating shaft to reset, and then driving the moving ceramic piece to rotate and reset to position A with the fixed ceramic piece, thereby closing the water channel; When the handle is turned from position A to drive the rotating shaft to turn right, the moving ceramic piece turns right, and the pull rod follows the right movement. The pull rod is separated from the outwardly expanded arc end of the torsion spring. At this time, continue to turn the handle to drive the water guide port of the moving ceramic piece to connect with the second water outlet.

[0005] Furthermore, the flange body is provided with 3-5 spring limit buckles around the central hole to adaptively adjust the deformation degree of the torsion spring.

[0006] Furthermore, the stop platform at the edge of the flange is provided with a stop edge to form an inwardly concave stop position, and the outwardly expanded arc-shaped end of the torsion spring can be detachably hooked on the inwardly concave stop position of the stop platform.

[0007] Furthermore, the pull rod has an external thread on its rod body, and the inner wall of the axial slot of the rotating handle is provided with a corresponding internal thread, and the pull rod is inserted into the axial slot by threaded connection.

[0008] Furthermore, the rotating handle includes a handle body and a rotating flange, the position of the rotating flange corresponds to the position of the flange stop, the rotating handle is provided with a delay switch indication mark on the left side of the rotating flange, and the rotating handle is provided with a manual switch indication mark on the right side of the rotating flange; the central axis of the rotating handle is provided with an assembly through hole, the inner wall of the assembly through hole is provided with a plurality of axial first gear teeth, the upper end of the rotating shaft is provided with axial second gear teeth meshing therewith, the upper end of the rotating shaft is arranged in the assembly through hole, and the linked rotation is achieved by the meshing between the gear teeth.

[0009] Furthermore, there is a rotating block at the lower end of the rotating shaft, and the rotating block is synchronously linked with the upper rotating shaft and the lower moving ceramic plate; the side wall of the rotating block is provided with an outwardly protruding elastic ejector pin, and the position of the elastic ejector pin corresponds to position A; the valve core shell is provided with a limiting hole for the elastic ejector pin to bounce into at the corresponding position A; when the outwardly expanded arc end of the torsion spring is hooked on the stop table, the elastic ejector pin bounces into the limiting hole of the valve core shell, making a snapping sound or a snapping feeling.

[0010] Furthermore, a valve core seat is provided, wherein the valve core seat has a water inlet hole, the valve core seat is fixed to the bottom of the valve core housing, and the fixed ceramic sheet is further fixed to the valve core seat.

[0011] After adopting the above structure, this patented product has dual modes of delay and normally open (manual switch). Users can choose delay or manual switch mode according to their own requirements, so that the product has a wider application scenario and better emergency effect; Secondly, the reasonable structural design, especially the fact that the water does not flow through the flange and its torsion spring, ensures that the water quality and temperature have little effect on the delay time. Therefore, the delay time of this patent is only affected by the friction between the ceramic plates, the friction of the O-ring and the interaction between the elastic force of the torsion spring. The performance and quality of the torsion spring are well controlled, which can well ensure its quality stability. Again, even if the torsion spring is damaged after long-term use, it will not affect the normal opening and closing functions. When the torsion spring is damaged, just switch the product to the normally open (manual switch) dual mode without affecting the use. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 8 As shown, the water guide port 311 of the fixed ceramic plate 32 is exactly located at the water stop platform 323 of the moving ceramic plate 31, and the fixed ceramic plate 32 is provided with a first water outlet 321 in the left turning direction of the moving ceramic plate 31 at position A (water stop platform 323), and a second water outlet 322 in the right turning direction of position A (water stop platform 323); Further features: The inner cavity of the rotating handle 1 has a flange 5, a middle hole 51 is provided in the middle of the flange 5 for passing the rotating shaft 2, and a stop 52 is provided at the edge of the flange 5. The position of the stop 52 of the flange 5 corresponds to position A, that is, in this embodiment, the position of the stop 52 of the flange 5 corresponds to the water guide port 311 of the moving ceramic plate 31 when the position is A; the main body of the flange 5 is provided with at least one spring limit buckle 53 around the middle hole 51, and five spring limit buckles 53 are provided in this embodiment to adapt the deformation degree of the torsion spring 54. The flange 5 is fixedly assembled on the upper part of the valve core housing 4.

[0016] A pull rod 14, whose rod body has an external thread 141, the handle is provided with an axial slot 16, the inner wall of the axial slot 16 is provided with a corresponding internal thread, the pull rod 14 is inserted into the axial slot 16 by threaded connection; the pull rod 14 moves on the flange 5 body as the handle rotates; A circular torsion spring 54, one end of which is a movable end and is set as an outwardly flared arc-shaped end 541, and the outwardly flared arc-shaped end 541 can be detachably hooked on the stop platform 52 of the flange 5, and the other end of the torsion spring 54 is set in the spring limit buckle 53 to realize the tension deformation of the circular torsion spring 54, so that its initial state presents a certain tensile deformation, which is beneficial to ensure the stability of the torsion spring 54 and is not easy to fall. Therefore, multiple spring limit buckles 53 are set in order to select a suitable spring limit buckle 53 in actual use, so that the torsion spring 54 is in a suitable tensile deformation state; the outwardly flared arc-shaped end 541 is located on the moving trajectory of the pull rod 14; the stop platform 52 at the edge of the flange 5 is provided with a stop edge 521 to form an inwardly concave stop position 522, and the outwardly flared arc-shaped end 541 of the torsion spring 54 can be detachably hooked on the inwardly concave stop position 522 of the stop platform 52.

[0017] The initial closed state is as follows Figure 4 As shown, when the rotating shaft 2 turns left (clockwise) and drives the moving ceramic plate 31 to turn left, the pull rod 14 moves leftward, and the pull rod 14 meets the outward arc end 541 of the torsion spring 54 at the position of the stop 52, and then pushes the outward arc end 541 to separate from the stop 52 (the concave position 522), aggravating the deformation of the torsion spring 54. At this time, the water guide port 311 of the moving ceramic plate 31 is connected to the first water discharge hole 321, and the rotating shaft 2 rotates to a preset position and stops. In practice, a limit position is generally set, such as Figure 5 As shown, when the limit position is reached, the rotating handle 1 is released, and the torsion spring 54 begins to overcome the deformation. In the process of overcoming the deformation, its outwardly expanded arc end 541 pushes the pull rod 14 to reset to the stop table 52, so that the rotating handle 1 rotates and resets to drive the rotating shaft 2 to reset, and then drives the moving ceramic plate 31 to rotate and reset to the position A with the fixed ceramic plate 32, thereby closing the waterway. Figure 6 As shown; like Figure 7 As shown, when the rotating shaft 2 rotates right to drive the ceramic plate 31 to rotate right, the pull rod 14 follows the rightward movement, and the pull rod 14 is separated from the outwardly expanded arc end 541 of the torsion spring 54. At this time, the handle 1 continues to be rotated to drive the water guide port 311 of the ceramic plate 31 to be connected with the second water outlet 322; in this state, since the torsion spring 54 is hooked on the gear stage 52 (concave gear position), it is completely separated from the pull rod 14. At this time, the opening and closing of the waterway only depends on the user's own right-turning rotating handle 1 or rotating the rotating handle 1 to position A to realize the manual switch of the waterway; the rotating handle 1 includes a handle body 11 and a rotating flange 12, the position of the rotating flange 12 corresponds to the position of the gear stage 52 of the flange 5, the rotating handle 1 is located on the left side of the rotating flange 12 with a delay switch indication mark 151, and the rotating handle 1 is located on the right side of the rotating flange 12 with a manual switch indication mark 152, as shown in FIG. Fig. 9As shown, it is convenient for users to distinguish between the delayed use area and the manual use area and select the use mode according to their own needs; the central axis position of the rotating handle 1 is provided with an assembly through hole 13, and the inner wall of the assembly through hole 13 is provided with a plurality of axial first gear teeth 131, and the upper end of the rotating shaft 2 is provided with an axial second gear tooth 21 meshing therewith, and the upper end of the rotating shaft 2 is arranged in the assembly through hole 13 by a screw 17, and the linked rotation is realized by the meshing between the gear teeth.

[0018] The lower end of the rotating shaft 2 has a rotating block 22, and the rotating block 22 is synchronously linked with the upper rotating shaft 2 and the lower moving ceramic plate 31.

The three first convex columns 25 are inserted into the three first notches 312 in a one-to-one correspondence, and the three first convex columns 25 are inserted into the three first notches 312 in a one-to-one correspondence, and the structural combination is realized. The device realizes synchronous linkage of the rotating block 22 and the moving ceramic plate 31; the side wall of the rotating block 22 is provided with an outwardly convex elastic ejector pin 23, and the position of the elastic ejector pin 23 corresponds to position A; the valve core housing 4 is provided with a limiting hole (not shown in the figure) for the elastic ejector pin 23 to bounce into at the corresponding position A; when the outwardly expanded arc end 541 of the torsion spring 54 is hooked on the stop platform 52 (the concave stop position 522), the elastic ejector pin 23 bounces into the limiting hole of the valve core housing 4, making a snapping sound or a snapping feeling, which helps the user to clearly feel that the faucet is closed.

[0020] The fixed ceramic sheet 32 ​​is further fixed to the valve core seat 6 through a fixing structure. The specific fixing structure is shown in the figure and will not be described in detail here.

[0021] In this embodiment, a hot and cold water dual valve core faucet is used. Fig. 9As described above, the double-valve core faucet housing 8 is connected to valve core cavities on the left and right sides. Generally, they are double valve core cavities for cold water and hot water. The two sets of the above-mentioned patented structures are respectively assembled in the cold water valve core cavity 81 and the hot water valve core cavity.

In addition, this patent has a simple structure and small usage space. The clever design concept ensures that the actual faucet will not be enlarged, and it is well adapted to various application scenarios.
