Description

Water tap

Technical Field

The invention relates to the technical field of household building materials, in particular to a faucet.

Background

The tap is a necessity for daily life. Most existing water taps are water taps for continuously discharging water, and some public places adopt push type time-delay water taps. The tap with continuous water outlet is mainly a tap with a spiral valve core or a ceramic valve core, when the tap rotates to a water outlet position, water outlet holes on different sealing sheets rotate to a communicated position from a mutually staggered position, so that water flows out. However, when the tap with continuous water outlet is used, a user needs to touch the switch twice, so that secondary pollution to hands is easily caused, and the tap is inconvenient to use. On the other hand, the tap that continuously goes out water easily causes the water waste because the people forget to close or can not close in time. The push type time delay faucet can solve the problem of short-time water consumption, but is not applicable to the condition that long-time water consumption is needed.

In summary, how to provide a faucet capable of meeting different water demands is a problem to be solved by those skilled in the art.

The switch handle 2 is fixedly connected with the upper valve core 5, and a rebound device which is convenient for the switch handle 2 to axially move and reset in a pressing state is arranged between the switch handle 2 and the tap shell 1.

An upper sealing piece 8 for aligning the axial hole for rotating to the self with the axial hole of the lower sealing piece 9 so as to realize water outlet of the faucet, the upper sealing piece 8 is fixedly connected with the lower valve core 7, and the lower sealing piece 9 is fixed on the faucet shell 1.

In the invention, when the switch handle 2 is pressed downwards by external force, the upper valve core 5 fixedly connected with the switch handle is driven to move downwards in the axial direction, so that the upper valve core 5 is forced to move downwards vertically; when the switch handle 2 is rotated by external force, the upper valve core 5 can also axially rotate in the faucet shell 1 on the basis of axial movement, and the upper valve core 5 can axially move and circumferentially move to drive the lower valve core 7 to circumferentially rotate, so that the upper sealing piece 8 fixedly connected with the lower valve core 7 synchronously rotates, and the axial hole of the upper sealing piece 8 rotates to a position aligned with the axial hole of the lower sealing piece 9, so that a passage is formed.

When the switch handle 2 is pressed downwards by external force, the upper valve core 5 can nest the lower valve core 7 from the upper part of the lower valve core 7 matched with the upper valve core 5, and the axial movement of the upper valve core 5 drives the lower valve core 7 to generate circumferential rotation through a similar sheave mechanism.

The water flow enters from the water inlet at the bottom of the faucet shell 1, flows through the axial hole of the lower sealing piece 9 and the axial hole of the upper sealing piece 8, flows into the interval area between the faucet shell 1 and the lower valve core 7, and then flows out from the water outlet, thereby achieving the purpose of water outlet. When the external force stops pressing or rotating the switch handle 2 in the opposite direction, under the action of the elastic restoring force of the rebound device or the external force of the opposite rotation, the switch handle 2 moves axially and returns to the original state to drive the upper valve core 5 to move upwards, and contrary to the process, the upper valve core 5 moves upwards or rotates to enable the lower valve core 7 to rotate reversely, the upper sealing piece 8 and the axial hole of the lower sealing piece 9 rotate and misplacement, the upper sealing piece 8 returns to the original position, the circulation channel is disconnected, and the water outlet is stopped.

The water tap provided by the invention provides a plurality of use modes for users. The switch handle 2 meets the two requirements of pressing and twisting simultaneously, short-time water outlet can be realized by pressing the switch handle 2, continuous water outlet can be realized by rotating the switch handle 2, the advantages of the pressing type faucet and the twisting type faucet are combined, and the use modes of the faucet are enriched. The user can change the water outlet mode according to the needs, thereby not only meeting the users with larger water demand, but also discharging water for a short time, avoiding secondary pollution to hands and water resource waste caused by forgetting to close or not closing the tap in time.

On the basis of the above-described embodiment, one of the upper spool 5 and the lower spool 7 is provided with a spiral rail extending in the axial direction, and the other is provided with a protrusion provided in cooperation with the spiral rail and sliding along the spiral rail.

In the invention, the upper valve core 5 is provided with a spiral track extending along the axial direction, and the lower valve core 7 is provided with a protrusion which is matched with the spiral track and slides along the spiral track.

When the switch handle 2 is pressed downwards by external force, the upper valve core 5 fixedly connected with the switch handle is driven to move downwards vertically, so that the bulge on the lower valve core 7 is forced to move downwards along one side of the spiral track of the outer edge of the upper valve core 5 in a circumferential direction, and the lower valve core 7 is driven to rotate in the circumferential direction; when the switch handle 2 is rotated by external force, the bulge on the lower valve core 7 moves downwards along the spiral track of the outer edge of the upper valve core 5 along one side of the circumferential rotation, and drives the lower valve core 7 to generate circumferential rotation.

Then, since the lower valve core 7 is fixedly connected with the upper sealing piece 8, the upper sealing piece 8 and the lower valve core 7 synchronously rotate; so the axial hole of the upper sealing piece 8 and the axial hole of the lower sealing piece 9 are aligned after rotation to form a passage, thereby achieving the purpose of water outlet.

When the external force stops pressing or reversely rotating, the switch handle 2 is restored to the original state, the upper valve core 5 is driven to move upwards, the bulge on the lower valve core 7 slides upwards to the original position along the spiral track, the lower valve core 7 is rotated to the original position, the axial holes of the upper sealing piece 8 and the lower sealing piece 9 are rotated and misplaced, the upper sealing piece 8 returns to the original position, and the water outlet is stopped.

The spiral track and the bulge are matched, the spiral track has a guiding effect on the bulge, the water outlet time of the faucet can be controlled by changing the length of the spiral track, and the abrasion can be reduced by using the spiral track, so that the operation is more convenient and labor-saving.

Alternatively, the spiral track may be disposed on the lower valve core 7, and the protrusion may be disposed on the upper valve core 5, where the spiral track is disposed in cooperation with the protrusion.

Alternatively, the protrusions matched with the spiral track may be columnar rolling pins 6, or may be other protrusions such as balls.
