Embodiment Construction

[0014] Please refer to figure 1 , a flow switching device of the present invention has the advantages of saving water, adjusting the flow of water outlet, and automatically recovering water outlet with a small flow after water is cut off. The flow switching device includes a valve body 10 , a water-saving piece 30 , a switching device 50 and a plug 70 .

[0015] Please refer to Figure 1 to Figure 3 , the valve body 10 is provided with a normally open water flow channel 12 and a normally closed water flow channel 14 along the axial direction. The water-saving piece 30 is placed in the valve body 10 and is arranged upstream of the water flow. A through hole 32 is defined in the middle of the water-saving sheet 30 .

[0016] The switching device 50 is arranged perpendicular to the downstream direction of the water flow of the valve body 10 . The switching device 50 includes a valve seat 52 vertical to the water flow direction, a switching shaft 54 ​​reciprocally sliding in t...

Abstract

The invention discloses a flow switching device comprising a valve. The valve is axially provided with a normally opened water flow channel and a normally closed water flow channel. A switching device is arranged on the downstream direction perpendicular to the water flow and comprises a valve seat perpendicular to the water flow direction and a switching shaft capable of sliding in the valve seat in a reciprocating manner. The switching shaft is provided with a large end and a small end. The small end is connected to a button and extends out of the valve, and the large end is connected against an elastic member mounted on the valve seat. In natural states, the force of the elastic member to the switching shaft allows the switching shaft to contain at a first position, and the large end of the switching shaft cuts off the water flow in the normally closed water flow channel; when the button is pressed, the switching shaft is moved to a second position, the normally closed water flow channel is opened, water from the normally closed water flow channel passes through the large end and the small end of the switching shaft, and the pressure difference of the water flow between the large end and the small end overcome the force of the elastic member to allow the switching shaft to be maintained at the second position. The state of the switching shaft at the second position can be maintained, and usage is facilitated.

Description

technical field [0001] The invention relates to a flow switching device. Background technique [0002] In order to save the flow of water in the waterway and achieve the purpose of saving water resources, people usually install a flow regulating mechanism in the waterway. People can adjust the size of the flow of water according to needs when using. [0003] However, when the existing flow regulating mechanism needs to switch the flow of the waterway, people need to continue to operate it, which is quite cumbersome to use. At the same time, the structure of the existing flow regulating mechanism is relatively complicated. Contents of the invention [0004] The invention provides a flow switching device, which overcomes the shortcomings of the background technology. The technical solution adopted by the present invention to solve its technical problems is: [0005] A flow switching device, comprising: a valve body, the valve body is provided with a normally open water f...
