The water dispenser convenient to assemble comprises a dispenser body, the dispenser body comprises a shell with a mounting cavity, the mounting cavity is provided with a front side opening, the dispenser body further comprises a front cover used for sealing the front side opening, and a surrounding edge protruding in the direction away from the front cover is arranged on the circumferential edge of the front cover; the shell is provided with a guide part, the surrounding edge is in guide fit with the guide part to pre-position the front cover, and a buckle structure for fixing the front cover and the shell is further arranged between the front cover and the shell. When the front cover and the shell are assembled, pre-positioning of the front cover can be realized through matching of the surrounding edge and the guide part, on the basis, the front cover and the shell are fixed, so that the assembling difficulty is reduced, the assembling efficiency is improved, and the front cover can be prevented from deviating from the mounting position in the mounting process through pre-positioning of the front cover; the front cover and the shell are fixed, favorable conditions are provided for fixing the front cover and the shell, the requirement for operators is low, the front cover and the shell are fixed in a buckled mode, operation is easy, and efficiency is high.

The application relates to the technical field of supramolecular, in particular to a ternary eutectic solvent as well as a preparation method and application thereof. The ternary eutectic solvent is prepared from component A, component B and component C, wherein the component A is a hydrogen bond donor, the component B is a hydrogen bond acceptor, and the component C is adenosine. The intermolecular interaction mode of the ternary eutectic solvent breaks the original strong force between adenosine molecules, so that the adenosine can be uniformly dispersed in the ternary DES system in the form of single molecules or small aggregates, thereby significantly improving the solubility of adenosine. Meanwhile, the existence of the ternary DES changes the dissolution and release behavior of the drug in the body, promotes the absorption of the drug, and greatly improves the bioavailability of adenosine.
