Further, the angle of the circular arc of cover body cross section is 230 ° ~ 330 °, can ensure to get out of the way centrifuge cup, can prevent again the too small fruit of producing effects affecting pernicious gas in centrifuge and absorb of cover body area.
Further, air admission hole be opened in the top of cover body inwall and middle part can ensure in centrifuge pernicious gas do not distribute not go out.
Further, because cover body inner wall lower distance centrifuge opening part is comparatively far away, only air inlet can be set on the top of cover body inwall and middle part.
Further, arched cover cap also can get out of the way centrifuge cup, makes the utility model more convenient to use.
Further, ventilation shaft is arranged valve and can ensure that induced-draught fan in use, can cut off the valve of other centrifuge ventilation shaft more than Liang Tai and two, during the work of bonding desk centrifuge, air draught efficiency is higher.
