Description

Technical Field

[0001] The utility model relates to a faucet with a filter, which can be adapted to a storage faucet. Background Art

[0002] At present, when replacing the filter element assembly on the thermostatic faucet, it is necessary to close the angle valve at the front end of the faucet before replacement, and after replacement, the angle valve must be opened again to allow water to flow, which is extremely inconvenient. Faucets are not always used in occasions that require filtered water. For example, water for cleaning the bathroom and drain water can use water that does not require filtration, but current faucets all use filtered water, which will consume filter materials and shorten the service life of the filter element. At the same time, the use of the filter element will also affect the flow rate, and sometimes it cannot meet the requirements of large flow rates. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present utility model is to provide a faucet with a filter.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0015] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered ranking of the indicated technical features. Thus, features defined with "first", "second" or "third" can explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" is two or more, unless specifically and explicitly defined otherwise.

[0016] In the present application, unless specifically and explicitly defined otherwise, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0017] In the present application, unless specifically and explicitly defined otherwise, the "upper" or "lower" of the first feature to the second feature can include the direct contact of the first and second features, or it can include the contact of the first and second features through another feature between them. Moreover, the "upper", "upper" and "upper" of the first feature to the second feature include the vertical direction of the first feature above and obliquely above the second feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The "lower", "lower" and "lower" of the first feature to the second feature include the vertical direction of the first feature below and obliquely below the second feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0018] With reference to the drawings, a filter faucet includes a water outlet channel 11, a switching valve 21 is arranged on the water outlet channel, a first outlet of the switching valve is communicated with a water outlet 12, at least one on-off valve 22 is arranged on the water outlet, each on-off valve corresponds to one water outlet mode, such as shower water, top spray and the like; a second outlet of the switching valve is communicated with a water inlet of a filter element assembly 30, a water outlet of the filter element assembly can be communicated with the water outlet, a one-way valve 31 is arranged between the water outlet of the filter element assembly and the water outlet, so that the water flow can only flow from the filter element assembly to the water outlet, that is, when the water outlet is at the first outlet, the water flow cannot flow from the water outlet of the filter element assembly into the filter element assembly, and the filter element assembly can also be replaced. At this state, there should be no filter element assembly, and the entire flow can be satisfied. But when filtered water is needed, the water outlet is at the second outlet, so that the water flow flows back to the water outlet after being filtered, and then flows out from the on-off valve.

[0019] Preferably, it also includes a shell 40, in which a mixing valve 50 is arranged. The first inlet of the mixing valve is connected to the cold water pipe 41, the second inlet of the mixing valve is connected to the hot water pipe 42, and the outlet of the mixing valve is connected to the water outlet channel, thereby achieving temperature regulation.

[0020] Furthermore, a water channel body 10 is provided in the shell, and the water outlet channel, switching valve, and water outlet can be provided in the water channel. A filter element assembly is provided below the shell, and the water inlet and outlet of the filter element assembly can be plugged into and matched with the water channel.

[0021] More specifically, the present invention controls the water flow of the switching valve by controlling the switching handle, which can flow to the filter channel (or to the filter element assembly) and the raw water channel (or to the outlet). When switching to the filter channel, the raw water enters the filter element assembly from the mixing valve and then returns to the raw water channel to realize the filtering function. When switching to raw water, the raw water channel does not pass through the filter element, but directly flows through the mixing valve and then flows into the raw water channel. A one-way mechanism is set in the filter channel and the raw water channel to make the two water channels independent.

[0022] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
