Ironing device

Abstract

The present invention discloses an ironing device, comprising: a water tank, an evaporator, a control valve and a booster pump. When a temperature sensor detects that a temperature of the evaporator is larger than or equal to a threshold value, the control valve opens, the booster pump starts to supply water from the water tank to the evaporator through a pipeline A, and the evaporator evaporates the liquid and sprays steam to iron clothing. When the temperature sensor detects that the temperature is less than the threshold value, the control valve shuts off the water supply from the water tank, the booster pump continues operating to supply the remaining water in a pipeline a to the evaporator, and then residual heat of the evaporator evaporates the remaining water in the pipeline a, thus to prevent the water from accumulating inside the evaporator.

1 . An ironing device, comprising:
 a water tank;   an evaporator, which is configured to evaporate liquid supplied by the water tank, wherein the evaporator is provided with a temperature sensor, which is configured to detect a temperature of the evaporator;   a control valve, which is communicated with a water outlet of the water tank, wherein the control valve is provided with a signal receiver that communicates with the temperature sensor; when the temperature of the evaporator is larger than or equal to a threshold value, the signal receiver receives a temperature signal fed back by the temperature sensor, so as to connect or disconnect a pipeline A between the water tank and the evaporator; and   a booster pump, which is arranged on a pipeline a between the control valve and the evaporator, and is configured to supply the liquid from the water tank to the evaporator.   
     
     
         2 . The ironing device according to  claim 1 , further comprising:
 a pipeline B, whose one end is communicated with the water tank and the other end is communicated with the evaporator; and   a low-pressure pump, which is arranged on the pipeline B, and is configured to supply the liquid from the water tank to the evaporator,   wherein an output pressure of the low-pressure pump is less than that of the booster pump.   
     
     
         3 . The ironing device according to  claim 2 , wherein the evaporator is provided with at least an atomization hole A communicated with the pipeline A and at least an atomization hole B communicated with the pipeline B. 
     
     
         4 . The ironing device according to  claim 3 , wherein the atomization holes B are provided in plurality and arranged around the atomization hole A. 
     
     
         5 . The ironing device according to  claim 4 , wherein the atomization holes B are symmetrically arranged on a periphery of the atomization hole A along a central axis of the atomization hole A. 
     
     
         6 . The ironing device according to  claim 4 , wherein an aperture of the atomization hole A is larger than that of the atomization hole B. 
     
     
         7 . The ironing device according to  claim 3 , wherein the evaporator includes a front cover and a middle layer, the atomization holes B are arranged at the front cover, the middle layer is provided with a guide flow channel, which is communicated with both the pipeline B and the atomization holes B. 
     
     
         8 . The ironing device according to  claim 7 , wherein the guide flow channel is serpentine, covering the area of the atomization holes B. 
     
     
         9 . The ironing device according to  claim 1 , wherein the control valve is a solenoid valve. 
     
     
         10 . The ironing device according to  claim 3 , wherein the ironing device further comprises a housing sleeved outside the control valve and the booster pump, a through hole is provided on the housing, the through hole is covered with a button connected to a valve of the control valve, and the button is configured to move axially along the through hole, so as to open and close the valve of the control valve.
