The invention provides a side-suction upward-discharge type range hood, and relates to the technical field of range hoods. A volute of a traditional range hood is positioned on the interior of a shell or the upward side of the interior of the shell, and greases are seriously accumulated on the shell and a volute component, thus cleaning is troublesome, the greases in the lampblack are difficult to filter, and the lampblack suction effect is poor. The range hood provided by the invention comprises a smoke inlet box and a blower component, and is characterized in that the smoke inlet box comprises a front plate and a rear plate, and a vertical smoke inlet chamber is formed in the smoke inlet box; the smoke inlet chamber is located between the front plate and the rear plate and opened upwards, a smoke inlet communicated with the smoke inlet chamber is formed on the lower end of the front plate, the outer side of the front plate is provided with a rotation panel which can open or close the smoke inlet, a smoke collection box is arranged above the smoke inlet box, a smoke collection chamber communicated with the upper port of the smoke inlet chamber is formed in the smoke collection box, the blower component is vertically arranged on the one side of the smoke collection chamber, and comprises an air inlet and an air outlet, and the air inlet is communicated with the smoke collection chamber. The range hood provided by the technical scheme has a good effect on filtrating greases, thus generating less influence on the blower component; and the discharge is environmentally-friendly, the efficiency of lampblack discharge is high, and the volume is small.

The touch display (12) is placed on the front side (111). The operating lever (13) is disposed on the front side (111), and the operating lever (13) is located near the upper edge (1111) and the side edge (1112).

The invention belongs to the field of fiber grating probe design, and provides a fiber grating three-dimensional force sense probe and a manufacturing method. The position of the fiber grating of the fiber grating three-dimensional force sense probe is set reasonably, and the sensitivity of the probe to force sense measurement and Accuracy is greatly improved. Among them, multiple fiber gratings are integrated and distributed in the probe body and handle, and are integrated with the probe body and handle, which can effectively avoid bonding failure and force transmission rate reduction caused by changes in material properties during the probe disinfection process And other issues. In addition, multiple fiber gratings are distributed to form different measurement units to measure the force sense of the three-dimensional surface of the probe, and the wavelength shift of the fiber grating in each measurement unit forms a difference output, which effectively improves the force sense of the probe. Measurement sensitivity and precision.

The invention relates to a rotating detonation engine experimental device, which belongs to the field of engine research. Including end cover, outer wall, inner cavity and fuel input control ring; screw holes and oxygen input port are distributed on the end cover; screw holes, fuel input port, igniter placement port and sensor placement port are distributed on the outer wall; There are screw holes, the oxygen is at the entrance of the annular combustion chamber, and the fuel is at the entrance of the annular combustion chamber; through holes are distributed on the fuel input control ring; in the rotary detonation engine experimental device of the present invention, the diameter of the oxygen at the entrance of the annular combustion chamber is 1mm , the number reaches one hundred; it can make the fuel and oxygen mix more evenly, and increase the possibility of continuous rotating detonation in the annular pipeline.
