detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment 1. This embodiment proposes a flow path conversion valve, as shown in FIG. The side pipes 111 of the pipes 11 are connected, one end of the straight pipes 112 of the two tee pipes is provided with a plug 13, and the connecting pipe 12 is provided with a valve 14 for controlling the connection or disconnection of the connecting pipe 12. The flow path conversion valve of this embodiment can be applied in the water purifier or connected to the external pipeline of the waterway. When the waterway does not need external equipment, close one end of the two straight pipes with an end cap, and connect the valve in the pipe Open, one end of one of the straight pipes without the end cap is the water inlet, and the other end of the straight pipe without the end cap is the water outlet, so that the water flows through the internal circulation of the connecting pipe; when external equipment is needed, the valve is closed and the end cap is opened , the water outlet and water inlet of the external device are respectively connected to one end of the two straight pipes, and the other ends of the two straight pipes are still the water inlet and the water outlet respectively, so that the water flows into the external device after passing through the water inlet, and then flows from the outlet The water outlet flows out, and then the water flow can be in the outer ring. The whole equipment is externally connected without adjusting the machine structure, which is easy to realize and reduces the cost of waterway reconstruction.

In order to switch the switching valve conveniently, there is a flow path switching handle 15 at the bottom of the connecting pipe 12 for switching the flow direction of the water in the pipe.

Among them, the external equipment can be filter elements, water heaters and other equipment, which can be set according to the needs in the actual use process. The water outlet is connected to the tap water pipe, and the water outlet is connected to the faucet. If the valve is opened and the other end of the two straight pipes is closed, the tap water will come out directly from the faucet. If the valve is closed, the end caps of the two straight pipes are removed, and the filter element is connected, then the faucet flows out of the filter element after purification. of purified water. In addition, this flow conversion valve can also be used as a conversion tool for adding filter elements. For example, the water inlet is connected to the primary filter element. If it is necessary to add a multi-stage filter element, the valve can be closed, and the end caps of the two straight pipes are removed to connect the multi-stage filter element. filter element, the faucet flows out the purified water purified by the multi-stage filter element.

Preferably, in this embodiment, the valve 14 is realized by a spherical valve with flexible opening and closing and good sealing performance, but of course it is not limited to a spherical valve.

In order to facilitate the connection of external equipment, the plugs are respectively set at the top of the two straight pipes 112, or the plugs 13 are respectively set at the bottom of the two straight pipes 112, which can save the length of the connecting pipeline, and the plugs are detachable , can be easily plugged in and out.

Embodiment 2, this embodiment proposes another flow path switching valve, as shown in Figure 2, including two main pipes 21, and a connecting pipe 22 connected between the two main pipes 21, the two main pipes One end of 22 is provided with a plug 23, and the connecting pipe 22 is provided with a valve 24 for controlling the connection or disconnection of the connecting pipe 22. The flow path conversion valve of this embodiment is similar to that of Embodiment 1, and can be applied in the water purifier or connected to the external pipeline of the waterway. When the waterway does not need external equipment, one end of the two main pipes is closed with an end cap , the valve in the connecting pipe is opened, the end of one of the main pipes without the end cap is the water inlet, and the end of the other main pipe without the end cap is the water outlet, so that the water flows through the inside of the connecting pipe; when external equipment is needed, the valve is closed, The end cover is opened, and the water outlet and water inlet of the external equipment are respectively connected to one end of the two main pipes, and the other ends of the two main pipes are still the water inlet and the water outlet respectively, so that the water flows into the external equipment after passing through the water inlet, and then from The water outlet flows out, and then the water flow can be outer ring, and the whole equipment is externally connected without adjusting the machine structure, which is easy to realize and reduces the cost of waterway reconstruction.

In order to facilitate production and manufacture, the two main pipes 21 and the connecting pipe 22 are preferably in one-piece structure.

In order to facilitate the connection of external devices, the plugs 23 are respectively arranged at the tops of the two main pipes 21, or the plugs are respectively arranged at the bottoms of the two main pipes 21, which can save the length of the connecting pipeline.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art may make changes, modifications, additions or replacements within the essential scope of the present utility model. It should also belong to the protection scope of the present utility model.
