This utility model discloses a dosage-divided, independently packaged structure for moisturizing gel for infantile eczema, belonging to the field of gel packaging technology. It addresses the problem of the lack of a scraping mechanism affecting user experience and efficiency. The structure includes a protective shell with a fixed base slidably mounted on its inner wall. A storage tube is fixedly connected to one side of the fixed base. Limiting grooves are provided at both the front and rear ends of the protective shell. This utility model, through the cooperation of the protective shell and the fixed base, with the storage tube on one side of the fixed base and a scraper on the other side, facilitates the removal of excess gel from the application area. Especially in the care of infantile eczema, timely scraping can alleviate the discomfort caused by excessive gel. Simultaneously, a removable cap increases the sealing of the packaging, effectively preventing air and external contaminants from entering, thereby extending the product's shelf life and ensuring that the gel quality remains unchanged during use.

The present invention relates to an optical position measuring device for detecting the relative position of two objects that can be moved relative to each other along at least one measuring direction, wherein the objects are connected to a first grating and to a second grating. Here, a light irradiation beam emitted by a light source is split into at least two sub-beams at a grating; the sub-beams are subjected to different polarization optical effects in the subsequent course of a scanning light path. After the sub-beams polarized in different ways are recombined at a grating, a plurality of phase-shifted, displacement-related scanning signals can be generated from the resulting signal beam in a detection unit. In the scanning light path of the sub-beams, no separate polarization optical device is arranged between the splitting and the recombination, and at least one of the gratings passed through is used as a polarization grating for generating different polarization optical effects on the sub-beams. Here, the polarization grating is designed so that diffraction orders with different polarization states are obtained at each incident location on the grating.

The invention discloses a reaction device continuously used for alcohol ketone condensation reaction, and relates to the technical field of chemical engineering, the reaction device comprises a reaction kettle main body and a reaction kettle cover hermetically connected with the reaction kettle main body, and also comprises a discharging assembly used for guiding out materials after reaction at the bottom of the reaction kettle main body; the discharging assembly comprises a discharging groove which is formed in the reaction kettle cover, and a discharging pipe with one end extending to the bottom of the reaction kettle main body is in internal threaded connection with the discharging groove; through mutual cooperation of the feeding assembly, the discharging assembly, the filtering assembly and the like, during production, a high-pressure conveying pump is controlled to be started, meanwhile, a throttling valve is controlled to be opened by a preset opening degree, an electric control three-way valve is controlled to enable the throttling valve to be communicated with a first feeding channel, and mixed raw materials are continuously injected into the reaction kettle main body; and the reaction product continuously produces materials with equal molar weight, and the quality in the reaction kettle is kept unchanged, so that continuous production is realized, and the production efficiency is improved.
