The working principle of the invention is as follows:
when the small water heater is used, the first sealing ring 14 is placed in the first sealing groove 101, the sleeve pipe 11 is sleeved outside the cold water pipe 10, and the connecting pipe 12 is arranged on one side convenient to be connected with the tap water pipe by rotating the sleeve pipe 11 according to the position (not shown in the figure) of the tap water pipe reserved in an actual use place; then, the impurity removing plug 131 is installed on the impurity removing pipe 130 through rotation, so that the filter screen 132 extends into the connecting pipe 12, impurities in water can be effectively intercepted, and the impurities are intensively deposited in the impurity removing pipe 130, and are convenient to intensively disassemble and clean; secondly, filtered tap water flows into the cold water pipe 10 through the water inlet 100, and water in the cold water pipe 10 flows to the water inlet end of the valve body 20 through the water discharge pipe 102 by opening the electromagnetic valve 103; then, the water in the water inlet end of the valve body 20 flows into the water outlet end of the valve body 20 from the water inlet cavity 210 and the water through port 211, the water accumulated in the water outlet end of the valve body 20 generates a downward reverse pressure on the sleeve 220, when the water inlet pressure is increased, the pressure of the water flowing into the water outlet end of the valve body 20 is increased, the water pressure pushes the sleeve 220 downwards to move towards the water inlet end side against the resistance of the spring 221, the gas in the sleeve 220 is discharged from the vent hole 230, so that the sleeve 220 gradually closes the opening of the water through port 211, and the water flow flowing to the water outlet end of the valve body 20 is reduced; when the water flow flowing to the water outlet end of the valve body 20 is too small, the sleeve 220 moves to one side far away from the water inlet end of the valve body 20 under the restoring force of the spring 221, so that the sleeve 220 gradually opens the opening of the water through hole 211 to improve the water flow flowing to the water outlet end of the valve body 20, finally, the dynamic balance of the water outlet pressure and the restoring force of the spring 221 is realized, and the water flow speed can be adaptively adjusted according to the water pressure of tap water; finally, the water flow at the water outlet end of the valve body 20 flows into the water storage tank 40 through the flow regulating valve 3, when the water is accumulated in the water storage tank 40 from bottom to top, the heating element 41 can effectively heat the water, and the heated hot water flows into the water inlet of the water level pipe 42 from the upper end and is finally discharged from the water outlet pipe 5; therefore, the small water heater can adaptively adjust the water flow speed according to the water pressure of tap water, stabilize the water pressure provided by external tap water, and effectively improve the heating stability of the small water heater so as to ensure that the heated water temperature is relatively stable, and the water inlet pipe 1 has strong universality and good use effect.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
