AI Technical Summary
Peristaltic pumps may suffer unexpected losses due to accidental opening of the cover during operation, especially when internal components are thrown out when the pump head rotates at high speed, affecting the working environment.
Design a peristaltic pump with a lid opening detection mechanism. The lid opening detection system consists of a magnet, a magnetic block, and a magnetic sensor. The system detects the lid opening status by the relative position change between the magnet and the magnetic block on the lid, and transmits a signal in time to control the pump head to stop rotating.
This technology enables the pump head to stop rotating promptly when the peristaltic pump is accidentally opened, thus avoiding losses and safety hazards and improving the safety and reliability of the equipment.

[0004] In view of the above problems, the utility model aims at providing a kind of peristaltic pump with uncovering detection mechanism, can transmit uncovering signal in time, avoid further loss caused when uncovering accidentally.
[0005] In order to solve the above technical problem, the utility model adopts the technical scheme as follows: a kind of peristaltic pump with uncovering detection mechanism, with shell, the shell is hinged with flap, uncovering detection mechanism is equipped between the shell and flap, the uncovering detection mechanism includes magnet, magnetic block, magnetic sensor and sensor fixed plate, the magnet is installed at the side of hinge support position of flap, the magnetic block is installed on the shell, and the magnet is abutted with the magnetic block when cover is closed, the sensor fixed plate is installed on the shell, the magnetic sensor is installed in the sensor fixed plate, and is arranged at the side of magnetic block.
[0006] In the above technical scheme, the shell is equipped with flap guide block, the side of hinge support shaft of the flap is equipped with flap guide column, the flap guide column is embedded in the guide slot on the flap guide block.
[0007] In the above technical scheme, the flap guide column is parallelly arranged with hinge support shaft, and the magnet is installed in the installation slot in the flap guide column.
[0008] In the above technical scheme, the sensor fixed plate is equipped with fixed seat, and the magnetic sensor is embedded in the fixed seat.
[0009] In the above technical scheme, the magnetic sensor is dry reed.
[0010] In the technical scheme, the sensor fixing plate is fixed outside the back plate of the shell and is fixed on the back plate through bolts, and the magnetism guiding block is arranged in the back plate and along the thickness direction of the back plate.
[0011] In conclusion, the technical scheme of the utility model has the beneficial effects compared with the traditional technical means: the cover opening detection mechanism of the utility model is composed of a magnet, a magnetism guiding block, a magnetic sensor and a sensor fixing plate, the magnet on the cover transmits an opening signal to the magnetic sensor, once the cover is opened, the magnet moves away from the magnetism guiding block with the cover, a signal is generated at the magnetic sensor, and it is known that the peristaltic pump is opened, at this time, the pump head can be stopped through other matching programs, and further loss caused by accidental opening is avoided.
