Description

Technical Field

[0001] This utility model relates to the technical field of water purification faucets, specifically to a water purification faucet with a drain pipe function. Background Technology

[0002] Generally, most existing faucets use a ball valve structure, but in kitchens or with water filtration systems, a corresponding purified water faucet (purifier faucet) is typically connected. The purified water faucet is usually installed on the side of the sink, separate from the regular faucet. It connects to the water purifier or other primary filtration device via a flexible hose. Installation is relatively simple, and users can install it themselves.

[0003] Chinese patent application number CN202111665447.7 discloses a water purifier faucet, comprising a faucet body, a filter, a heater, a valve core, a water outlet pipe, a filtered water outlet pipe, a heated water inlet pipe, a heated water outlet pipe, and an exhaust pipe. The filtered water outlet pipe is connected to the water outlet end of the filter and the valve core, the water outlet pipe and the heated water inlet pipe are connected to the valve core, the heated water inlet pipe is connected to the water inlet end of the heater, the heated water outlet pipe is connected to the water outlet end of the heater, and the heated water outlet pipe is also connected to the water outlet pipe. The valve core can control the filtered water outlet pipe to alternately connect to the water outlet pipe or the heated water inlet pipe. The water outlet pipe is arranged in the faucet body and defines an exhaust channel between itself and the faucet body. The exhaust pipe is connected to the exhaust port of the heater and is also connected to the exhaust channel.

[0004] Here, with the help of the attached diagram, we can see that the water purifier faucet has a valve body, operating handle, valve core, and water outlet pipe. In actual use, those skilled in the art can understand that when the operating handle of the faucet is turned on, water begins to flow from the outlet pipe, and when the operating handle is turned off, the water flow stops. We know that at this time, purified water will remain in the outlet pipe. Because it is not emptied in time, when used again the next day, most users will not notice that the water that has been in the outlet pipe overnight (or for an even longer period of time) will first enter the cup before new purified water is added to the outlet pipe. The purified water that has been ingested overnight is easily ingested by users, which is very bothersome for some users, resulting in a poor user experience. Therefore, there is a market demand for a purified water faucet that can empty the outlet pipe. Utility Model Content

[0005] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a water purifier faucet with a drain pipe function, which can overcome the technical problem that water still accumulates after the water is discharged from the outlet pipe of the existing water purifier faucet, and can drain the outlet pipe after the water stops flowing from the faucet, making it convenient and reliable to use.

[0006] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0007] A purified water faucet with a drain pipe function includes a valve body, a water outlet pipe installed on the valve body, a valve core assembly installed in the valve body, and a handle for controlling the valve core assembly. The valve core assembly includes a valve shell, a valve stem, a moving valve plate, and a stationary valve plate. The axis of the valve shell is horizontal and is provided with a first through hole and a second through hole that pass through vertically. The valve stem is rotatably connected to the valve shell and keeps coaxial with it. One end of the valve stem is snapped onto the moving valve plate. The moving valve plate and the stationary valve plate are rotatably connected coaxially, and the stationary valve plate is snapped into the valve shell.

[0008] The side wall of the static valve plate is provided with a first water passage groove, which is directly opposite to the first through hole. The end face of the static valve plate is provided with a second water passage groove, which is circumferentially offset from the first water passage groove.

[0009] The moving valve plate is provided with a third water channel. When the third water channel is directly opposite the second water channel, the water in the valve body is discharged from the channel formed by the second and third water channels. When the third water channel is misaligned with the second water channel, the first and third water channels are connected to form a water inlet channel.

[0010] Preferably, the valve body is connected to a drain pipe and a water inlet pipe, and the valve body is provided with a bending channel with a 90-degree bend, and the drain pipe and the water inlet pipe are installed in parallel.

[0011] Preferably, the valve body is provided with a base portion, and a threaded pipe is sleeved on the base portion, and the drain pipe and the inlet pipe are installed inside the threaded pipe.

[0014] Preferably, the water outlet pipe is made of a transparent material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model improves the valve core in the valve body so that when the operating handle is turned, the valve stem rotates, causing the moving valve plate to rotate while the stationary valve plate remains stationary. At this time, the combination of the moving and stationary valve plates enables the switching of water circuit opening and closing, which can realize the normal output of purified water. When the handle is closed, the water inlet channel is closed, and the drain channel and the water outlet pipe are connected at the same time to drain the water accumulated in the water outlet pipe, so as to meet the user's needs.

[0017] 2. In this utility model, the valve body structure design facilitates installation and maintenance, and enables rapid repair and replacement of parts.

Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

[0031] Example:

[0032] refer to Figure 1 As shown, a purified water faucet with a drain pipe function resembles an ordinary faucet in appearance, but... (continued reference) Figure 2 , Figure 3 and Figure 4The valve assembly comprises a valve body 1, a water outlet pipe 2 mounted on the valve body 1, a valve core assembly 3 installed inside the valve body 1, and a handle 4 for controlling the valve core assembly 3. The valve core assembly 3 includes a valve housing 31, a valve stem 32, a moving valve plate 33, and a stationary valve plate 34. The valve housing 31 has a horizontal axis and is provided with a first through hole 311 and a second through hole 312 running vertically through it. The valve stem 32 is rotatably connected to the valve housing 31 and remains coaxial with it. One end of the valve stem 32 is engaged with the moving valve plate 33. The moving valve plate 33 and the stationary valve plate 34 are coaxially rotatably connected, and the stationary valve plate 34 is engaged inside the valve housing 31. The first through hole 311 is used for water inlet, and the second through hole 312 is used for water outlet. The valve stem 32 can rotate coaxially and drive the moving valve plate 33 to rotate. This is generally designed as a 90-degree drive, thereby switching the water path to achieve water flow or shut-off.

[0033] For more details, please refer to the following: Figure 4 , Figure 5 and Figure 6 The side wall of the static valve plate 34 is provided with a first water passage groove 341, which is directly opposite to the first through hole 311. The end face of the static valve plate 34 is provided with a second water passage groove 342, which is offset from the first water passage groove 341 in the circumferential direction.

[0034] A third water channel 331 is provided on the moving valve plate 33. When the third water channel 331 is directly opposite the second water channel 342, the water in the valve body 31 is discharged from the channel formed by the second water channel 342 and the third water channel 331. When the third water channel 331 is misaligned with the second water channel 342, the first water channel 341 and the third water channel 331 are connected to form a water inlet channel.

[0035] Therefore, this solution improves the valve core inside the valve body 1 so that when the operating handle 4 is turned, the valve stem 32 rotates, causing the moving valve plate 33 to rotate 90 degrees while the stationary valve plate 34 remains stationary. At this time, the structure of the moving valve plate 33 and the stationary valve plate 34 (the first water channel 341, the second water channel 342, and the third water channel 331 are connected or closed) realizes the switching of water circuit opening and closing. This allows normal purified water to be discharged. When the handle 4 is closed, the water inlet channel is closed, and the drain channel and the water outlet pipe 2 are connected to drain the water accumulated in the water outlet pipe 2 to meet the user's needs.

[0036] To facilitate drainage, a drain pipe 8 and an inlet pipe 7 are connected to the valve body 1. The valve body 1 is provided with a bending channel 11, which has a 90-degree bend. The drain pipe 8 and the inlet pipe 7 are installed in parallel. This facilitates the installation of the drain pipe 8.

[0037] To facilitate the installation and fixing of valve body 1, valve body 1 is provided with a base part, and a threaded pipe 5 is sleeved on the base part. Drain pipe 8 and water inlet pipe 7 are installed inside the threaded pipe 5.

[0038] To improve the tightness of the valve housing 31 during assembly, a sealing ring 6 is provided between the first through hole 311 and the second through hole 312 on the valve housing 31, and the sealing ring 6 fits on the inner wall of the valve body 1.

[0039] To facilitate inspection, maintenance and replacement of parts, the valve stem 32 includes an inner stem 321 and an outer stem 322. The inner stem 321 is located inside the valve housing 31, and the outer stem 322 is fixed to the outer end of the inner stem 321. Multiple sealing grooves 323 are provided on the circumferential side of the inner stem 321.

[0040] To ensure clear visibility of water accumulation in outlet pipe 2, outlet pipe 2 is made of transparent material. Outlet pipe 2 can be made of transparent plastic or a flexible transparent hose.

[0041] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
