Abstract
The present disclosure relates to a bioprinter spray head assembly, comprising a mounting block having a passage and a spray head mounted in the passage, wherein a first flow channel is provided in the mounting block, one end of the first flow channel is provided with a port communicating with the passage; the spray head comprises an equal diameter portion away from an outlet of the passage and a reduced diameter portion close to the outlet of the passage, wherein a second flow channel is formed between the reduced diameter portion and the passage, an opening is formed between the reduced diameter portion and the port to communicate the first flow channel and the second flow channel, and the equal diameter portion is configured to occlude the port. The adjustment of the circulation area of the spray head assembly may be achieved by changing the relative positions of the reduced diameter portion and the port, so that the adjustment is convenient and easy to carry out, and there is a favorable implementability.
