The utility model discloses a consumable detection device for a 3D printing extruder. The consumable detection device comprises a printing head shell, a wire extruding channel is vertically formed in the inner side of the printing head shell in a penetrating mode, and a detection channel, an adjusting groove and a square groove are formed in the inner side of the printing head shell. The inner wall of the detection channel is fixedly connected with a first fixing shaft and a clamping block. Through an innovative mechanical conduction structure, when the consumables are inserted from the top, the balls are pushed and eject the deflector rod, so that the distance between the magnet block on the deflector rod and the Hall sensor is changed, the entry state of the consumables is detected in real time, and meanwhile, the detection accuracy is improved. The Hall sensor can accurately sense the actual diameter of the consumables according to the difference of the shifting distance of the shifting rod caused by small change of the diameters of the consumables, real-time accurate control over the extrusion flow is achieved in combination with the driving motor and the transmission gear set, and the problem that in the prior art, the extrusion amount is unstable due to uneven diameters of the consumables is solved; and the consistency of printing quality is obviously improved.

Embodiments of the present application disclose a service processing method and device, equipment and computer readable storage medium. The service processing method in the embodiments receives a service request sent by a service requester, detects whether a service type corresponding to the service request is a domain name service type, and obtains a detection result. If the detection result indicates that the service type is the domain name service type, a domain name result corresponding to the service request is obtained from a cached domain name result, that is, the cached domain name result corresponding to the service request is directly obtained, so that the obtained domain name result is more accurate, and the service processing flow is reduced, so that the service processing process is faster. Finally, based on the obtaining condition of the domain name result corresponding to the service request, a return strategy of the domain name result corresponding to the service request is determined, and the domain name result is returned to the service requester based on the return strategy, so that the result corresponding to the service request can be quickly and accurately returned.
