The utility model discloses a kind of denture is used to oral impression protection device, including the protective box with top being open, the protective cover of open shielding sealing is arranged in protective box top, and protective cover is detachably arranged, the protective box and protective cover are prepared using heat preservation, light shielding material, the storage cylinder is installed in the inboard of protective box, the storage cylinder side is equipped with several air vents. The denture is used to oral impression protection device, by storing oral impression in the sealed environment of heat preservation and protecting it, reduce the influence of external environment temperature to oral impression, while dry agent is arranged in protection device, for dehumidification, avoid oral impression to be influenced by temperature and humidity and appear discoloration, softening etc., the influence of external force to oral impression can be also reduced by the protection device, avoid oral impression to be stressed deformation even breakage in storage or transportation process, oral impression is better protected.

A sprocket protective sleeve and a sprocket suitable for the protective sleeve are disclosed. The protective sleeve covers the circumferential sides of several chain teeth of the sprocket and includes a tooth protector and a through-hole. The tooth protector is cylindrical and has several tooth-enclosing portions protruding outwards from its circumferential sidewalls corresponding to the chain teeth. An accommodating space with the same cross-sectional shape as the sprocket is formed inside the tooth protector. Side openings communicating with the accommodating space are formed on both sides of the tooth protector. A fixing portion is also provided on the tooth protector. The sprocket is positioned within the accommodating space through one of the side openings, and the chain teeth are covered and fixed by the tooth-enclosing portions. The through-hole passes through the fixing portion and the locking portion of the sprocket to securely engage and fix the tooth protector to the sprocket. Accordingly, using the sprocket protective sleeve as a component to protect the sprocket and its transmission with the chain can reduce wear on the sprocket during transmission, and by replacing worn sprocket protective sleeves, equipment operation and maintenance costs can be reduced.

A sprocket guard and a sprocket suitable for the sprocket guard, wherein the sprocket guard comprises a side plate and a tooth sleeve, the side plate has the same cross-sectional shape as the sprocket, the periphery of the side plate is provided with tooth protrusions corresponding to the sprocket teeth, and a through hole is formed in the center of the side plate; the tooth sleeve has tooth covering portions protruding outward corresponding to the tooth protrusions, the periphery contour of the side plate corresponds to the two side opening contours of the tooth sleeve, the tooth sleeve is combined with the periphery of the side plate through one side opening to form a containing space with one side opening, and the sprocket is fixedly arranged in the containing space through the side opening so that the sprocket teeth are fixedly covered by the tooth covering portions and the shaft hole of the sprocket is aligned with the through hole. In this way, the sprocket guard is used to protect the sprocket and the transmission components cooperating with the chain, which can reduce the damage of the sprocket during transmission, and the maintenance cost of the equipment can be reduced by replacing the worn sprocket guard.

This invention relates to the field of flexible wearable energy devices, and particularly to a wireless wearable self-adhesive sensor that generates electricity using saliva and its preparation method. The preparation method includes the following steps: preparing MXene nanosheets and silk fibroin powder; adding MXene nanosheets, pyrrole, and silk fibroin powder to a polyethylene solution and mixing them thoroughly, then adding a borax mixture and glycerin to react and obtain a conductive hydrogel; coating the conductive hydrogel onto both sides of a membrane, sealing it with the membrane, and introducing saliva to obtain the wireless wearable self-adhesive sensor that generates electricity using saliva. This invention utilizes a conductive hydrogel Ti3C2 / PPy / SF / PVA and a membrane to prepare a wireless wearable self-adhesive sensor that generates electricity using saliva. It possesses self-adhesive properties, eliminates the need for additional wearable devices such as teeth protectors, offers high comfort, and minimizes foreign body sensation. This sensor generates electricity using saliva to charge biosensors, detection devices, etc., enabling wireless wearable applications.
