Description

Technical Field

[0001] The present invention relates to the technical field of three-way joints, and in particular to an automatic switching three-way joint. Background Art

[0002] A three-way joint is a common connector with three pipe openings in life. The forming of a three-way joint is to flatten a pipe blank larger than the diameter of the three-way to about the size of the three-way diameter, and drill a hole at the position where the branch pipe is to be stretched; the pipe blank is heated, placed in a forming die, and a punching die for stretching the branch pipe is installed inside the pipe blank; under the action of pressure, the pipe blank is radially compressed, and during the radial compression process, the metal flows towards the branch pipe direction and forms a branch pipe under the stretching of the punching die; the whole process is formed through the radial compression of the pipe blank and the stretching process of the branch pipe part. Three-way joints are often used in places such as kitchens and bathrooms where water needs to be discharged. It is difficult for a three-way joint to conveniently achieve the switching of the water discharge action. In the prior art, when applied to a bathroom, a control switch often needs to be added to the shower pipe of a shower column. The installation of a common three-way joint requires wall drilling and is difficult to simply connect to one end of the shower pipe of the shower column for portable use; a spray gun is often provided in the bathroom, and the spray gun is directly connected to the water inlet end, and the pipe is continuously kept under high pressure, there is a risk of bursting. The connection and installation of a common three-way joint at the water inlet end of the spray gun generally has a general effect on sharing the pressure in the pipe. Summary of the Invention

[0003] Other features and advantages of the present invention will be described in the following specification, and will be partially obvious from the specification, or understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained through the structures specifically pointed out in the specification, claims, and other specification drawings.

[0004] The objective of the present invention is to overcome the above deficiencies and provide an automatic switching three-way joint.

[0005] To achieve the above objective, the technical solution of the present invention is:

[0006] An automatic switching three-way joint includes a first water outlet head, an external thread, a three-way shell, a water inlet head, a second water outlet head, and a switching component. The three-way shell and the external thread are an integrally formed structure. The second water outlet head, the water inlet head, and the first water outlet head and the three-way shell are an integrally formed structure. The switching component is installed inside the three-way shell. The switching component includes a mating seat, a first sealing ring, a second sealing ring, a central shaft, and a ring. The second sealing ring is embedded and installed on the mating seat. The first sealing ring is embedded and installed at the top head of the central shaft. The ring is located inside the three-way shell and is on the side close to the second water outlet head.

[0007] Preferably, the central axis includes a central axis body, a V-shaped notch, and a convex ring. The V-shaped notch is prefabricated on the central axis body. There are two V-shaped notches in total. The bottom end of the central axis body is integrally formed with the convex ring, and the convex ring is in close fit with the inner wall of the circular ring.

[0008] Preferably, the bottom end of the central axis is fitted and installed on the circular ring, and the central axis moves vertically along the inner wall of the fitting seat.

[0009] Preferably, the water inlet head includes a water inlet pipe and a water inlet. The water inlet is provided in the water inlet pipe, and the water inlet communicates with the inside of the three-way shell.

[0012] Preferably, external threads are provided on the first water outlet head, the water inlet head, and the second water outlet head.

[0013] The working principle of the present invention:

[0014] When using this automatic switching three-way joint, when the water inlet head 4 is opened, water surges into the inside of the three-way shell 3. At this time, the first water outlet head 1 and the second water outlet head 5 discharge water. When the water passes through the V-shaped notch 642, the water pressure causes the entire central axis 64 to move downward, so that the first water outlet head 1 is closed and the second water outlet head 5 discharges water unidirectionally. As shown in the figure, at this time, the three-way joint is in the state of unidirectional water discharge of the second water outlet head 5; when the second water outlet head 5 is closed, the water inlet head 4 stops supplying water, and the water pressure pushes the central axis 64 upward. At this time, water can flow out from the first water outlet head 1, and an efficient switching water discharge action can be simply realized inside the three-way shell 3. When installing the automatic switching three-way joint on the shower pipe of the shower column, there is no need to add a control switch, nor to install it by breaking the wall. It can be simply connected to one end of the shower pipe of the shower column for portable use. When installing the automatic switching three-way joint at the water inlet end of the spray gun in the bathroom, the automatic switching three-way joint installed at the water inlet end of the spray gun has a good effect on sharing the pressure in the pipe, and can effectively prevent the pipeline from bursting due to long-term high pressure in the pipe. The cooperation of the fitting seat 61, the central axis 64, the circular ring 65, and the V-shaped notch 642 can realize the switching water discharge action inside the three-way joint, and the use effect is good. Figure 5 shown, at this time the three-way joint is in the state of unidirectional water discharge of the second water outlet head 5; when the second water outlet head 5 is closed, the water inlet head 4 closes the water inlet, and the water pressure pushes the central axis 64 upward. At this time, water can flow out from the first water outlet head 1, and an efficient switching water discharge action can be simply realized inside the three-way shell 3. When installing the automatic switching three-way joint on the shower pipe of the shower column, there is no need to add a control switch, nor to install it by breaking the wall. It can be simply connected to one end of the shower pipe of the shower column for portable use. When installing the automatic switching three-way joint at the water inlet end of the spray gun in the bathroom, the automatic switching three-way joint installed at the water inlet end of the spray gun has a good effect on sharing the pressure in the pipe, and can effectively prevent the pipeline from bursting due to long-term high pressure in the pipe. The cooperation of the fitting seat 61, the central axis 64, the circular ring 65, and the V-shaped notch 642 can realize the switching water discharge action inside the three-way joint, and the use effect is good.

[0015] By adopting the above technical solutions, the beneficial effects of the present invention are:

[0016] The present invention optimizes the switching component. The structure inside the switching component is simple, and the switching of water outlet can be realized inside the three-way joint. When the automatic switching three-way joint is installed on the shower pipe of the shower column, no control switch needs to be added, nor is it necessary to install it by breaking the wall. It can be simply connected to one end of the shower pipe of the shower column for portable use. When the automatic switching three-way joint is installed at the water inlet end of the spray gun in the bathroom, the automatic switching three-way joint installed at the water inlet end of the spray gun has a good effect on sharing the pressure in the pipe, and can effectively prevent the pipeline from bursting due to long-term high pressure in the pipe.
