Referring to fig. 1 to 6, shown quick-open case of energy-conserving pottery, including business turn over water piece 1 and switch plate 2, business turn over water piece 1 fixed mounting is in tap switch department, offer the first inlet opening 1a with the tap water inlet intercommunication on the business turn over water piece 1, still offer the first apopore 1b with the tap delivery port intercommunication on the business turn over water piece 1, switch plate 2 rotatably installs on the top surface of business turn over water piece 1, switch plate 2 is coaxial with business turn over water piece 1 and switch plate 2 covers first inlet opening 1a and first apopore 1b, the blind hole 2a of intercommunication first inlet opening 1a and first apopore 1b is seted up to switch plate 2 bottom.
The faucet is the same as a common faucet in the market in structure, the interior of the faucet is closed, water flow cannot directly flow from a water inlet to a water outlet, and the water flow can only flow from the water inlet to the water outlet through a valve core;
as shown in fig. 3, the water tap 4 is a water tap, the water tap 4 feeds water through a water inlet pipe 4a, the water tap 4 discharges water through a water outlet pipe 4b, the partition plate 4c disconnects the water inlet pipe 4a from the water outlet pipe 4b, the water inlet pipe 4a is provided with a second water inlet hole 4a1 communicated with the first water inlet hole 1a, and the water outlet pipe 4b is provided with a second water outlet hole 4b1 communicated with the first water outlet hole 1 b; the shifting fork 5 is clamped with the switch piece 2 so as to drive the switch piece 2 to rotate on the water inlet and outlet piece 1, and a handle 5a is arranged on the outer side of the shifting fork 5 and used for a user to rotate the shifting fork 5;
when the shifting fork drives the switch piece 2 to rotate so that the valve core is opened, water flows from a water inlet of the water faucet to a water outlet of the water faucet through the first water inlet hole 1a, the blind hole 2a and the first water outlet hole 1b in sequence, and then the water is discharged from the water faucet;
as shown in fig. 4, when the shifting fork drives the switch plate 2 to rotate so that the valve core is closed, water flow sequentially passes through the first water inlet hole 1a and the blind hole 2a from the water inlet of the water faucet and then stays on the top surface of the water inlet and outlet plate 1, and the water faucet stops water outlet.
The first water inlet hole 1a is a circular hole penetrating through the water inlet and outlet sheet 1 along the axis of the water inlet and outlet sheet 1, and the blind hole 2a is a slotted hole extending outwards in the radial direction from the axis of the switch sheet 2.
Because business turn over water piece 1 and switch plate 2 are coaxial, so first inlet opening 1a and blind hole 2a communicate all the time to make no matter switch plate 2 rotates many degrees on business turn over water piece 1, rivers still can enter into inside blind hole 2a through inlet tube 4a, second inlet opening 4a1, first inlet opening 1 a.
When the shifting fork drives the switch plate 2 to rotate so that the blind hole 2a and the first water outlet 1b are overlapped, the rotating angles of the shifting fork are different, the overlapped part of the blind hole 2a and the first water outlet 1b is also different, and further, the projected area of the overlapped part of the blind hole 2a and the first water outlet 1b is also different, the projected area of the overlapped part of the blind hole 2a and the first water outlet 1b determines the flow of water flow which can flow into the first water outlet 1b from the blind hole 2a, when a user rotates the shifting fork so that the blind hole 2a moves from one end with a smaller caliber of the first water outlet 1b to one end with a larger caliber of the first water outlet 1b, the flow of the water flow flowing into the first water outlet 1b from the blind hole 2a is gradually increased, and therefore the user can easily control the water outlet amount of the faucet.
The central angle of the arc of the first outlet hole 1b is 180 degrees.
Compare in traditional tap's 90 degrees switchings, this tap's switching angle is 180 degrees for the user has had bigger operation interval, thereby can adjust tap's water yield more accurately, avoids the user to exert oneself slightly and open tap to the end promptly, causes the problem of the too big extravagant water source of rivers.
The bottom end of the water inlet and outlet sheet 1 is fixedly provided with a gasket 3, two end faces of the gasket 3 are respectively abutted against the bottom surface of the water inlet and outlet sheet 1 and the inner wall of the faucet, and the inner diameter of the gasket 3 is larger than that of the first water inlet hole 1 a.
The gasket 3 is used to provide a sealing function for reducing the requirement for the fit of the faucet to the bottom surface of the water inlet and outlet sheet 1.
The water inlet and outlet sheet 1 and the switch sheet 2 are made of ceramic materials.
The ceramic has good chemical stability, long service life, and no rusting and mildewing, and is suitable for being used as a valve core of a faucet.
The outer circumference of the switch plate 2 is provided with fork grooves 2b which are uniformly distributed around the axis of the switch plate 2, the number of the fork grooves 2b is at least two, and the fork grooves 2b vertically extend downwards from the top surface of the switch plate 2.
The shifting fork 5 transmits torque to the switch plate 2 through the shifting fork groove 2b, so that a user can rotate the handle 5a to drive the switch plate 2 to rotate through the shifting fork 5.
The superposition position of the fork groove 2b and the top surface of the switch plate 2 is provided with a chamfer 2b 1.
The chamfer 2b1 facilitates insertion of the working end of the shift fork 5 inside the fork slot 2b by an installer or an automatic installation device.
The top surface of switch piece 2 is provided with vertical undercut's instruction groove 2c, instructs groove 2c to be the arc shape recess with the arc line coincidence of first apopore 1 b.
The indication groove 2c is used for guiding an installer to install the switch piece 2 on the water inlet and outlet piece 1 in the forward direction, and the installer is prevented from reversely installing the switch piece 2.
The utility model discloses a theory of operation:
when a user drives the switch plate 2 to rotate through the shifting fork 5 so that the valve core is opened, water flows from a water inlet of the water faucet to a water outlet of the water faucet through the first water inlet hole 1a, the blind hole 2a and the first water outlet hole 1b in sequence, and therefore water is discharged from the water faucet;
when the user rotates the shifting fork 5 to rotate the switch plate 2 so that the blind hole 2a moves from the end with the smaller caliber of the first water outlet hole 1b to the end with the larger caliber of the first water outlet hole 1b, the flow of the water flowing into the first water outlet hole 1b from the blind hole 2a increases gradually, so that the user can easily control the water outlet amount of the faucet, and when the user rotates the shifting fork 5 by 90 degrees under normal conditions, the water outlet amount of the faucet is 4/10 when the faucet is fully opened, which is enough to meet the normal washing requirement, thereby playing the role of water saving;
when the user drives the switch piece 2 to rotate through the shifting fork 5 to enable the valve core to be sealed, water flow stops on the top surface of the water inlet and outlet piece 1 after sequentially passing through the first water inlet hole 1a and the blind hole 2a from the water inlet of the water faucet, and the water faucet stops water outlet.
It should be understood that the above-described embodiments are merely illustrative of the preferred embodiments of the present invention and the technical principles thereof. It will be understood by those skilled in the art that various modifications, equivalents, changes, and the like can be made to the present invention. However, these modifications are within the scope of the present invention as long as they do not depart from the spirit of the present invention. In addition, certain terms used in the specification and claims of the present application are not limiting, but are used merely for convenience of description.
