DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 5 A direct drinking water faucet comprises a faucet body 1, a faucet outlet 3 installed on the upper part thereof and a water outlet head 6 installed on the left part of the lower end of the faucet outlet 3, a Y-type three-way valve 7 is installed on the left side of the faucet outlet 3, a connecting pipe 8 is connected to one end of the left part of the Y-type three-way valve 7, the end of the connecting pipe 8 is connected to the water outlet head 6, and both ends of the right part of the Y-type three-way valve 7 are connected to water delivery pipelines, and a valve for opening and closing two water delivery pipelines at the same time is installed at the bottom of the faucet body, and the two water delivery pipelines are respectively connected to the raw water pipeline and the filtered water pipeline through the valve, so that after the valve is opened, the two water delivery pipelines are respectively introduced into the raw water and the filtered water at the same time;

[0018] A gear 21 is fixed to the end of the valve stem of the Y-type three-way valve 7, and a rack 10 is meshed and connected to the rear of the gear 21, and the rack 10 is L-shaped. A casing 4 is fixed to the left end of the faucet water outlet 3, and a button 5 is slidably connected inside the casing 4. A guide rod 15 is fixed to the middle of the right end of the button 5, and the end of the guide rod 15 penetrates into the inside of the faucet water outlet 3 and is fixed to the rack 10. A large spring 16 is connected between the right end of the button 5 and the left end of the faucet water outlet 3. The upper and lower ends of the button 5 are elastically connected to card beads 19, and the upper and lower ends of the button 5 are provided with side grooves 17. The card beads 1 9 is located inside the side groove 17, a small spring 18 is connected between the card bead 19 and the bottom of the side groove 17, the upper and lower ends of the inner wall of the housing 4 are provided with card grooves 20, the card bead 19 and the card groove 20 are plugged in one by one, when the button 5 protrudes from the housing 4, the water delivery pipeline filled with raw water is connected with the water outlet 6 through the Y-type three-way valve 7, and the water outlet 6 discharges raw water at this time, and when it is necessary to switch to filtered water, the button 5 is pressed into the housing 4, and the button 5 squeezes the large spring 16 while driving the rack 10 to move horizontally to the right, and the rack 10 drives the gear 21 to rotate clockwise, and the gear 21 drives the valve stem to rotate The button 5 moves to rotate the valve ball of the specific Y-shaped channel in the Y-shaped three-way valve 7. As the button 5 moves to the point where the card bead 19 corresponds to the card slot 20, the small spring 18 in the compressed state bounces the card bead 19 and plugs it into the card slot 20. At this time, the button 5 is clamped by the upper and lower card beads 19 to limit the button 5. At the same time, the gear 21 is rotated 120 degrees through the meshing transmission of the rack 10 and the gear 21. In this way, the valve ball drives the Y-shaped channel to change the connected water path, so that the water delivery pipeline filled with filtered water is connected to the water outlet 6 through the Y-shaped three-way valve 7. At this time, the water outlet 6 discharges filtered water. When it is necessary to continue to use raw water, the button 5 is continuously pressed, and the button 5 continues to squeeze the large spring 16.
