Novel vacuumizing device

The utility model provides a novel vacuumizing device which comprises a box body, an air extractor and a plurality of vacuumizing pipes, a vacuumizing opening is formed in the top of the box body, the air extractor is communicated with the vacuumizing opening through a connecting pipe, the vacuumizing pipes are vertically placed in the box body, the tops of the vacuumizing pipes are communicated with the vacuumizing opening, and the air extractor is communicated with the vacuumizing opening through a connecting pipe. And an extraction opening is formed in the side wall of the vacuumizing pipe. The vacuum-pumping pipe is arranged in the box body and is provided with the plurality of extraction openings, so that evaporated water vapor is extracted in time, the vacuum-pumping uniformity of the upper part and the lower part of the equipment is ensured, the temperature difference of all places of the equipment during heating is reduced, and the water vapor evaporated from materials can be extracted in time at +/-2
