Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a rotary switching water filter faucet. Background Technology

[0002] A faucet water purifier refers to a miniature water purification device that is directly installed and suspended on a household faucet. Currently, faucet water purifiers use different principles to switch between raw and purified water. Common faucet filter water path switching structures resemble piston structures, using the up-and-down movement of a piston to switch water paths. After repeated use, faucet filters are prone to problems such as leakage, inability to withstand high pressure, and simultaneous water flow from both paths. While there are also rotary water control structures, these are usually located inside the main unit and are generally more complex.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a rotary switching water filter faucet with an external rotary switching structure. It has a simple structure, is easy to use, and does not require a handle. Water path switching can be completed directly by rotating the rotating base.

[0005] The solution adopted by this utility model to solve the technical problem is: a rotary switching water filter faucet, including a body and a rotating body. The body is provided with an inlet and an outlet. The rotating body includes a valve core rotatably installed in the body and located between the inlet and the outlet for controlling the opening and closing of the inlet and outlet, and a rotating seat located outside the body for driving the valve core to rotate. The rotating seat is provided with a filter chamber, and the rotating seat is provided with a filter outlet communicating with the filter chamber. The valve core is also provided with a filter channel for communicating the inlet and the filter chamber.

[0006] Furthermore, in order to install the faucet universally on the water outlet pipe, the main body is provided with a spherical connector for connecting to the tap water outlet pipe. The water inlet is located on the spherical connector. The spherical connector includes a connector sleeve, a sealing ring, and a ball head for installation on the water outlet pipe. The ball head is fixed on the main body. The connector sleeve is movably fitted on the ball head. The sealing ring is located inside the connector sleeve to ensure sealing contact with the water outlet pipe. The sealing ring is provided with a spherical cavity adapted to the shape of the ball head to ensure that the ball head can rotate relative to the connector sleeve, thereby ensuring that the main body can rotate relative to the water outlet pipe.

[0007] Furthermore, to ensure that the main body can rotate relative to the connector sleeve, the main body is provided with an upwardly extending connecting post, the ball head is integrally formed on the upper end of the connecting post, the diameter of the ball head is larger than the diameter of the connecting post, and the lower end of the connector sleeve extends radially inward with a limiting flange located below the ball head for limiting engagement with the ball head.

[0008] Furthermore, in order to rotatably install the valve core between the inlet and the outlet, the outlet is located below the inlet, and a cylindrical cavity for installing the valve core is horizontally provided on the body between the inlet and the outlet. The valve core is rotatably installed in the cylindrical cavity, and a raw water groove is provided circumferentially on the outer surface of the valve core to connect the inlet and the outlet. The arc length of the raw water groove is greater than half the circumference of the valve core to ensure that the raw water groove connects the inlet and the outlet.

[0009] Furthermore, in order to enable the valve core to rotate and switch between the raw water and filtered water channels, the filtered channel includes an axially penetrating water passage through the valve core and a radially disposed water passage notch on the valve core that communicates with the water passage. The water passage notch is offset from the raw water groove on the valve core so that the inlet can be switched to communicate with the raw water groove or with the water passage notch by rotation.

[0010] Furthermore, in order to ensure that the valve core reciprocates between one end of the raw water groove and one end of the water passage notch, a limiting groove is provided on the valve core on the opposite side of the junction of the raw water groove and the water passage notch. The arc length of the limiting groove is slightly larger than the distance between one end of the raw water groove and one end of the water passage notch. The main body is provided with a limiting rod that is inserted into the limiting groove to limit the rotation angle of the valve core, thereby ensuring that the valve core reciprocates between one end of the raw water groove and one end of the water passage notch.

[0011] Furthermore, for the installation of the filter element, the rotating seat is provided with an annular protrusion above the filter outlet to form a filter chamber. The filter element is installed inside the annular protrusion. The filter element is provided with a first sealing ring for sealing contact with the annular protrusion. The rotating seat is provided with an annular seat on the outer periphery of the annular protrusion. An inlet chamber communicating with the filter channel is formed between the annular seat and the annular protrusion.

[0012] Furthermore, in order to guide the water flow upward and outward from the filter element downward, the filter element has a filter inlet on its upper side and a filter outlet on its lower side. The annular seat has an internal thread on its upper side, and a shell covering the outer periphery of the filter element is threaded onto the internal thread. A second sealing ring is fitted on the shell for sealing contact with the annular seat. A water passage cavity is formed between the side wall of the shell and the outer wall of the filter element to guide the water flow from the filter inlet into the filter element.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure and is easy to use. By integrating the valve core into the rotating seat, rotating the rotating seat can drive the valve core to rotate and switch the water path. Since the connector sleeve is fitted on the outlet pipe, the operation is very convenient. Furthermore, the rotation of the valve core will cause the inlet to coincide with the raw water groove or the water passage notch, thereby switching the water flow from the raw water channel or the filter channel to achieve water path switching. In addition, the present invention is also provided with a limiting groove. By inserting the limiting rod into the limiting groove, the main body is restricted from reciprocating between the raw water groove end and the water passage notch end, ensuring the convenience of operation.
