[Detailed ways]

As shown in Figures 1-4, a device for removing residual cold water in the pipeline includes a straight pipe 11 connected to the water inlet pipe, a slanted branch pipe 12 connected to the straight pipe 11, and connected to the slanted branch pipe. 12 The cleaning device 2 at the water outlet end that can be automatically turned on by the water pressure in the pipe, and the cold water storage device connected to the upper end of the straight pipe 11 to collect and store the initially remaining cold water in the water inlet pipe so that the incoming hot water flows into the cleaning device 2 first 3. The cold water storage device 3 includes a cold water box 30, a cold water chamber 31 is arranged on the cold water box 30, a water flow channel 32 is arranged at the bottom of the cold water chamber 31, an air vent 33 is arranged on the top of the cold water chamber 31, and a straight pipe 11 The water outlet is communicated with the above-mentioned water flow channel 32, and a floating box 34 that can rise and fall with the water level in the cold water chamber 31 is also equipped with a floating box 34 that can float up and down with it to close or open the vent hole 33 Sealing sheet 35.

The cold water box 30 includes a cylindrical box body 301 and a box cover 302 buckled at the opening of the box body. The box cover 302 is sleeved with a sealing rubber ring 303 that can closely match the inner wall of the box body 301. The water flow channel 32 is located in the box body 301. The bottom of the bottom, the vent 33 is located on the above-mentioned box cover 302. After the box body 301 and the box cover 302 are sealed and buckled, the inner space is a cold water chamber 31, and the bottom of the cold water chamber 31 is provided with an upward guide column 310, and the floating box 34 is set on the guide column 310 and floats up and down along the guide column 310 .

The cleaning device 2 includes a pipe body 21, one end of the pipe body 21 is connected with the inclined branch pipe 12, and the other end of the pipe body 21 is inclined downward, and a piston rod 22 and a return spring 23 sleeved on the piston rod 22 are movable in the pipe body 21. The center of the piston rod 22 is provided with a water outlet channel 220, the inner end of the piston rod 22 is a big end, and there is a gap 25 for draining water between the big end and the inner wall of the pipe body 21, and the outer end of the piston rod 22 is connected with a pipe extending outside the pipe body 21. The nozzle 24 is provided with a water spray port 240 communicating with the water outlet channel 220, and the lower side of the downwardly inclined end of the pipe body 21 is provided with a water discharge port 210 for draining the residual water in the pipe body 21.

When the utility model is in use, the hot water is discharged by the heater under pressure to squeeze the remaining cold water in the water inlet pipe. Since a slanted hole is formed at the connection between the straight pipe 11 and the inclined branch pipe 12, the cold water is preferentially discharged from the straight pipe under pressure. 11 straight line injects in the cold water box 30, and cold water can not flow in the inclined branch pipe 12. During the design, the cavity of the cold water box 30 is enough to store the residual cold water in the water inlet pipe. When the water level in the cold water box 30 rises, the floating box 34 in the cold water box 30 rises, and the vent hole 33 above the cold water chamber 31 is closed. Plug the seal. After the water flow fills the cold water tank, the hot water in the water inlet pipe enters the cleaning device 2 from the inclined branch pipe 12 on one side of the straight pipe 11, and the piston rod 22 on the cleaning device 2 slides outward along the pipe body 21 under the water pressure and The return spring 23 is compressed, and the hot water passes through the water outlet channel 220 in the center of the piston rod 22 and the water nozzle 221 protruding from the pipe body at the outer end of the piston rod 22 to flush the human body, thus avoiding the cold water directly spraying on the human body when the user initially uses it superior. After stopping use, the cold water in the cold water box 30 flows into the cleaning device 2 under the action of its own weight, and part of the cold water slowly flows out through the water outlet channel 220 in the center of the piston rod 22 and the water spray port 240 on the nozzle 24, and remains in the pipe body 21 Another part of the cold water is completely discharged through the gap 25 between the body of pipe 21 and the inner end of the piston rod 22 and the drain port 210 on the body of pipe 21, so that cold water is directly sprayed on the human body when avoiding reuse.
