The lower part of the box is divided by a partition wall having a small diameter communication hole to form a filtration chamber within the partition wall, and the lower part of the filtration chamber is communicated with the pipe line, and the upper part of the filtration chamber is connected to the outside of the air valve. An air valve connected to a communicating pipe, and characterized in that the pipe is provided with an on-off valve.
