Abstract: A range hood includes a body having a space formed therein, and multiple grooves are formed in the inside of the space. The body includes an opening in the underside thereof. The opening communicates with the space. A case includes multiple rails which are slidably located in the grooves. A frame is located in the space and includes a blower. A driving unit is located in the space and connected to the case so as to lift and lower the case by moving the rails along the grooves.

Abstract: A kitchen hood includes a casing and a room is defined in the casing. A window is defined in the casing and communicates with the room. A switch box is positioned in the room by a positioning module. The switch box has a switch cover to which multiple switches are connected. An activation module is connected to inside of the room and the switch box. The activation module controls the switch cover to be exposed from the window or hidden in the window.

Abstract: A water dispensing device includes a main tank which has a water intake disposed thereon for adopted to connect to an outer water supply. The main tank has a diverting hole defined therein. A first water valve is disposed in the diverting hole. A second tank is received in the main tank. The second tank has a water inlet defined therein. The water inlet is connected to the diverting hole such that water stored in the main tank flow from the second tank to the water inlet. A second water valve is disposed on the water inlet and abutted against the first water valve to abut against the first water valve for communicating the water inlet with the first water valve.

Abstract: A liquid fuel for a colored flame can be filled in containers of various shapes to make various artworks which can produce a colored flame when burning. The liquid fuel for a colored flame comprises a flame-coloring ingredient and a main combustible ingredient that are mixed during a heating process. The flame-coloring ingredient is made by mixing a chromogenic agent selected from a group consisting of metal chloride, metal bromide and boric acid with the water and the glycerin or with the water, the glycerin and the ethyl alcohol in a specific weight ratio. The main combustible ingredient is made by mixing the glycerin, the water and alcohol compounds in a specific weight ratio. Hence, the liquid fuel for a colored flame not only ensures a vivid and bright flame but increases the ignition point and combustion stability, thus solving the problems of low ignition point and high volatility.
