The invention provides a sliding key mechanism and an electronic device. The key mechanism comprises a shell and a key module, wherein the shell comprises a containing groove and an opening part; the opening part is provided with a first end and a second end opposite to the first end; the key module comprises a circuit board and a plurality of keys; the keys are arranged on the circuit board; thecircuit board and the keys are arranged in the containing groove, and the ends of the keys protrude out of the opening part; and the keys can be arranged between the first end and the second end in asliding manner so as to be in different positions. The key structure and the electronic device provided by the invention have the following beneficial effects: for the key module, the positions of the keys can be transversely or vertically adjusted, thereby breaking through the design mode that the traditional keys are in fixed positioned. Thus, the key structure and the electronic device can meet different needs of different people such as left-handers and the like.

The invention discloses a heat exchange separator capable of preparing ice crystals and salt crystals simultaneously by utilizing seawater. The heat exchange separator comprises a closed refrigerant evaporation part, an ice scraping motor, an ice scraping knife, a shell and a salt crystal collecting container, wherein the top of the shell is connected with the refrigerant evaporation part; the lower part of the shell is conical; the lower part of the shell is connected with the salt crystal collecting container through a salt crystal outlet receiving pipe and a salt crystal collecting control valve; the ice scraping knife is arranged on an output shaft of the ice scraping motor; the ice scraping knife is mounted on the top of the shell and is contacted with an ice crystal crystallization part of the refrigerant evaporation part; an ice crystal outlet receiving pipe is arranged on the top of the shell; an ice crystal collecting control valve is mounted on the ice crystal outlet receiving pipe; and a seawater inlet receiving pipe and a fresh seawater outlet receiving pipe are arranged on the shell. According to the heat exchange separator, the temperature of the seawater is reduced by utilizing heat absorption caused by evaporation of the refrigerant; and fresh water is crystallized and separated out of the seawater and the salt crystals are separated out by utilizing the extraction technology principle. The heat exchange separator separately collects the ice crystals and the salt crystals, integrates preparation of the ice crystals and the salt crystals, and increases the effectively utilization ratio of the seawater.

The invention discloses a portable and adjustable wax knife tool, which comprises a handle body and a blade device. The handle body is also provided with a threaded hole. The handle body is fixedly connected; a vertical piece is fixedly connected to the center of the lower end of the knife handle body, and the vertical piece is located at the center of the blade device. The advantages of the present invention: the blade device of the present invention selects different types of blades for nested connection, and can choose the required specifications for use, which is convenient and practical; The blades are rotated to the rear for backup without disassembly. In the present invention, a vertical piece is fixedly connected at the center of the lower end of the handle main body to increase the density of the wax storage space, so that the wax storage effect is better, and the liquid wax has better adhesion, so that the wax flower can be drawn easily. The effect is better.
