Description

Automatic uncapping device of PCR reaction tube Technical Field The application belongs to the technical field of automatic uncovering of reaction tubes, and particularly relates to an automatic uncovering device of a PCR reaction tube. Background The ‌ reaction tube has very wide application prospect in hospitals, has important roles in bacterial culture identification and biomedical research, is an indispensable test consumable in the bacterial culture identification process in laboratories, judges bacterial genus ‌ through the biochemical reaction characteristics of bacteria on the reaction tube, and mainly comprises application in PCR reaction and importance of the bacterial genus ‌ to medical diagnosis in hospitals. PCR (polymerase chain reaction) is a classical method in molecular diagnostic assays, whereas the design and technical characteristics of the reaction tube, which acts as a carrier for the PCR reaction system, have an important impact on the efficiency and accuracy of the PCR reaction. The automatic cover opening device for the PCR reaction tube is disclosed in CN211712585U, and belongs to the technical field of medical supplies. The device comprises a clamping structure, a cover opening structure and a pipe frame, wherein the clamping structure for clamping the reaction pipe is arranged on the pipe frame, the cover opening structure capable of sliding is arranged on the pipe frame, and the cover opening structure is used for opening a pipe cover of the reaction pipe. The utility model can clamp and fix the reaction tubes on the tube rack by arranging the clamping structure, prevent the reaction tubes from being overturned when being opened, and can uncap the reaction tubes in the same row by arranging the uncapping structure, thereby saving time. According to the utility model, the anti-slip soft rubber pads are arranged in the arc-shaped inner parts of the fixed clamping plate and the movable clamping plate, so that the friction force is increased, the reaction tube can be better fixed when the cover is opened, the reaction tube can not be overturned, and the tube cover of the reaction tube can be smoothly opened. However, in this application, it is difficult to clean the inside of the reaction tube after use, and the manual cleaning is too time-consuming and labor-consuming, which may result in an increase in the number of uncleaned reaction tubes, and the supply of uncleaned reaction tubes is not required, which greatly reduces the use efficiency and is not beneficial to the subsequent use and cleaning. Disclosure of utility model The application aims to solve the problem of cleaning the inside of a reaction tube, and provides an automatic cover opening device for a PCR reaction tube. The technical scheme includes that the automatic cover opening device of the PCR reaction tube comprises a fixing frame, wherein a button is arranged at the upper end of the surface of the fixing frame, a pressing connecting pipe is connected below the button, a cover is fixedly connected below the pressing connecting pipe, a pressing column is installed inside the cover, a powerful spring is arranged on the periphery of the pressing column, a detergent storage bin is arranged below the cover, a washing machine outflow opening is connected below the detergent storage bin, a transmission column is connected to the lower surface of the washing machine outflow opening, a sponge ball is connected to the outer surface of the transmission column, a hairbrush is arranged on the surface of the sponge ball, and a silica gel pad is fixedly installed at the bottom of the transmission column. Through adopting above-mentioned technical scheme, when carrying out inside washing to the reaction tube, press post and powerful spring through the installation button, make the liquid detergent flow into the liquid detergent and store in the storehouse, after the outflow is suitable, stop pressing, the liquid detergent can stop flowing out, conveniently control the outflow of liquid detergent, remaining liquid detergent can be placed in the liquid detergent stores in the storehouse, the waste that the excessive use caused has not only been avoided, the convenience in the clearance reaction tube has also been improved, in flowing into the transmission post through the cleaning machine egress opening, can make the better circulation of liquid detergent adsorb the liquid detergent in the sponge ball, make the sponge ball can more fully even adsorb the liquid detergent, the better comprehensive clearance in inside to the reaction tube has been convenient, the convenience of use has been improved, the part that the sponge ball did not wash is further washd through the installation brush, make the inner wall of reaction tube cleaner, the effect has improved convenience and neatly for its cleanness, can prevent the inside striking damage to the reaction tube in the middle of the cleaning process, the whole protection reaction tube tha
