The base 11 and the upper cover 12 are both provided with mounting grooves 113 for mounting the filter screen 2, and the filter screen 2 is mounted in the mounting grooves 113 of the base 11 and the upper cover 12 to divide the flowing space into a first steam chamber 111 and a second steam chamber 112. The intake hole 121 communicates with the first steam chamber 111. As shown in fig. 5, the top of the first steam chamber 111 is an inclined surface, and the inclined surface gradually inclines downwards from the air inlet hole 121 to the inside of the steam chamber. The inclined angle b of the inclined surface is 20-80 degrees. Set up the reducible steam of inclined plane and volatilize from the inlet port, can adhere to on the inclined plane when the steam in first steam chamber upwards volatilizees, along with the slowly formation drop of water of the accumulation of steam, the drop of water drips along the inclined plane in first steam chamber 111.

As shown in fig. 2, an impurity tank 117 for storing impurities is disposed in the bottom of the first steam chamber 111, a through slag discharge hole 115 is disposed on a sidewall of the impurity tank 117 of the base 11, and a ball valve 116 is disposed at the slag discharge hole 115. The arrangement of the slag discharge hole 115 can facilitate the cleaning of impurities in the impurity groove 117, the situation that the upper cover 12 is required to be opened to clean the impurities every time is avoided, and the opening and closing of the slag discharge hole 115 can be controlled by the ball valve 116.

A water storage tank 118 is arranged in the bottom of the second steam chamber 112, a drainage hole 114 is arranged on the side wall of the water storage tank 118 of the base 11, and the float valve assembly 3 is arranged at the drainage hole 114. As shown in fig. 6, the float valve assembly 3 includes a support frame 31, a float support 32, a float 33, a rubber stopper 34 and a valve mouth 35; the support frame 31 is fixedly arranged in the water storage tank 118 of the second water vapor chamber 112, the floating ball support 32 is hinged with the support frame 31, the floating ball 33 and the rubber stopper 34 are arranged on the floating ball support 32, and the floating ball 33 is positioned on the outer side of the rubber stopper 34. The valve mouth 35 is installed in the drainage hole 114, and one end of the rubber stopper 34 is installed on the ball support 32, and the other end is located at the opening of the valve mouth 35 for opening and closing the valve mouth 35. As shown in FIG. 4, the height c of the water storage tank 118 is smaller than the height of the float holder 32 in the second steam chamber 112.

As shown in fig. 4, the liquid level pipe 4 is disposed outside the housing 1, the base 11 is further provided with a liquid level channel 122, the liquid level channel 122 is communicated with the second steam chamber 112, one end of the liquid level channel 122 is communicated with the second steam chamber 112, and the other end is communicated with the liquid level pipe 4.
