Cold fog machine dispense with discharge of pressure relief water and capable of recycling pressure relief water

Abstract

The invention discloses a cold fog machine dispense with discharge of pressure relief water and capable of recycling the pressure relief water. The cold fog machine comprises a first filter with a water inlet, wherein the water inlet of the first filter is connected with a water inlet pipe, a water outlet of the first filter is connected with the water inlet end of a water inlet electromagnetic valve through a guide pipe, the water outlet end of the water inlet electromagnetic valve is connected with the water inlet end of a second filter through a guide pipe, the water outlet end of the second filter is connected with the water inlet end of a water pump through a guide pipe, a water-free low-pressure protection switch is arranged between the water outlet end of the second filter and the water inlet end of the water pump, the water outlet end of the water pump is connected with the water inlet end of a pressure relief electromagnetic valve through a guide pipe, the water outlet end of the pressure relief electromagnetic valve is connected with the water inlet end of the second filter through a guide pipe, and a spray nozzle is also arranged at the water outlet end of the water pump in a connecting way. The cold fog machine disclosed by the invention has the advantages of attractive appearance, simple and reasonable structure and design, convenience for use, energy saving and environment friendliness.

Description

technical field [0001] The invention relates to a spraying device, in particular to a cooling fog machine which is used for humidifying and cooling the environment, discharges no pressure relief water and can recycle the pressure relief water. Background technique [0002] In the past, due to structural design flaws in the cooling mist machines used in the market, when the water pump of the cooling mist machine stops working, the nozzle will stop spraying, but because there is still high pressure in the water pipe, the high pressure leads to the high pressure in the water pipe The water will continuously drip down from the nozzle, which will cause a lot of inconvenience to wet the ground and pedestrians; while the traditional cooling fog machine manufacturers deal with this pressure water by removing it from the cooling fog machine body, so that these Clean residual pressure water is discharged as waste water and causes environmental pollution. [0003] In addition, there i...

Problems solved by technology

[0002] In the past, due to structural design flaws in the cooling mist machines used in the market, when the water pump of the cooling mist machine stops working, the nozzle will stop spraying, but because there is still high pressure in the water pipe, the high pressure leads to the high pressure in the water pipe The water will continuously drip down from the nozzle, which will cause a lot of inconvenience to wet the ground and pedestrians; while the traditional cooling fog machine manufacturers deal with this pressure water by removing it from the cooling fog machine body, so that these Clean residual pressure water is discharged as waste water and causes environmental pollution

[0003] In addition, there is no pressure regulating device between the outlet and inlet of the water pump of the traditional cooling mist machine, which will cause the pressure of the water outlet of the pump to be too high and cause the spray end to bear too high pressure, which will cause the accessories of the water outlet of the pump to be easily damaged

The traditional cold fog machine does not have an overpressure one-way return valve, so it cannot effectively adjust the water pressure
