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.

The utility model belongs to the field of water dispensers, and provides a multifunctional electric valve structure assembly which comprises a machine shell provided with a containing cavity. The valve element fixed ceramic chip is installed in the containing cavity, and a water through hole is formed in the valve element fixed ceramic chip; the driving module is arranged on the machine shell, a valve element movable ceramic chip is connected to the driving module, the valve element movable ceramic chip stretches into the containing cavity and movably abuts against the valve element fixed ceramic chip, and a water supply hole is formed in the valve element movable ceramic chip. Compared with the prior art, the utility model has the advantages that a driving mode of the driving motor is adopted, so that the valve core movable ceramic chip is propped against the valve core fixed ceramic chip, corrosion and abrasion of impurities in water are effectively resisted, and the service life of the valve is prolonged; and meanwhile, the overlapping area between the water supply hole and the water through hole can be adjusted under the relative rotation of the valve element and the movable ceramic chip, so that the accurate control over the water outlet amount is achieved, and the flow requirements in different scenes are met.

The utility model relates to a falling rod sealing device belongs to the technical field of industrial equipment sealing. Including falling rod frame and installing elastic support mechanism on the falling rod, and the falling rod is hung in the downside of falling rod frame through chain, elastic support mechanism includes locating block, stud, adjusting nut and spring, locating block fixed mounting is in the falling rod frame, the stud is set in the locating block through the coupling, and the adjusting nut of locating block below is sleeved on the stud, and the spring is set between adjusting nut and falling rod, and the falling rod is closely contacted with the trolley sealing plate through the elastic force provided by spring. The utility model adds the elastic support mechanism on the basis of existing falling rod, so that in addition to falling rod can rely on the self weight and trolley top surface contact, still can rely on the elastic force that elastic support mechanism adds and trolley top surface contact, ensure that the sealing is good, avoid the air leakage.

The scheme of the utility model belongs to the field of forming molds, and particularly relates to an electronic part processing forming mold convenient to demold, which comprises a base, a mold mechanism is arranged above the base, the mold mechanism comprises a base table, a channel is arranged in the middle of the base table, a mold table is further arranged above the base table, and the mold table is arranged on the base table. A plurality of mold grooves are formed in the upper end of the mold table, an inner cavity is formed in the mold table, ejection holes are formed in the bottoms of the mold grooves, ejection rods are arranged in the ejection holes in a penetrating mode, and the same ejection plate is fixed to the lower ends of the ejection rods. Through the linkage design of the ejector rod, the ejector plate and the first air cylinder, the parts can be quickly ejected out of the mold groove after machining is completed, the demolding efficiency is remarkably improved, a spring auxiliary reset mechanism ensures accurate return of the ejector rod, clamping stagnation is avoided, the device is particularly suitable for machining electronic parts in batches, the manual part taking time is shortened, and the damage risk is reduced.
