The application relates to the hair dryer technical field and provides a hair dryer with a rear-mounted temperature controller, which comprises a hair blowing head, a heating assembly and a temperature controller arranged in the hair blowing head; the heating assembly comprises a heating wire support and a hollow heat insulation cover, the first heating wire is wound around the outer periphery of the heating wire support, and the hollow heat insulation cover is arranged on the outer periphery of the first heating wire; the temperature controller is arranged in the hollow heat insulation cover and located at one end of the heating assembly far from an air outlet, and the side of the temperature controller far from the air outlet is provided with the second heating wire; a handle is arranged in the handle and is connected with the hair blowing head in communication, and the air making assembly is used for supplying air to the hair blowing head. According to the application, the temperature controller is arranged at one end of the heating assembly far from the air outlet, and the second heating wire is arranged at the side of the temperature controller far from the air outlet, so that the reaction sensitivity of the temperature controller is ensured, the interference of the temperature controller on the airflow in the hair blowing head is reduced, and the airflow noise is reduced.

This invention relates to the field of water-based paint treatment technology, specifically to a water-based paint treatment device and process for wooden furniture production. Technical Problem: In existing technologies, dust on the surface of wooden furniture is blown away using an air gun, causing the dust to fly in the air and easily inhaled by workers, posing a health hazard. Technical Solution: A water-based paint treatment device for wooden furniture production includes a base frame and a lifting component; the lifting component, used to move the table legs upwards, is connected to the middle of the base frame. The water-based paint treatment device for wooden furniture production obtained by the present invention uses the felt fibers to brush away dust from the surface of the table legs. Simultaneously, during movement, the elastic rope sinks into the recesses of the table legs, and the felt fibers on the elastic rope also brush away dust from these recesses. Furthermore, impurities stuck in the recesses are also carried out by the elastic rope, preventing dust residue on the table legs from affecting the subsequent water-based paint spraying quality.

This invention provides a graded embolization protection device, belonging to the field of vascular interventional medical device technology. The device includes a delivery guidewire, with multiple protection units fixedly arranged at intervals at the distal end of the guidewire. Each protection unit has a proximal open end and a distal closed end, and each protection unit has a flexible support frame for support at a target location. Multiple open areas are formed on the support frame, and a soft, elastic filter membrane is arranged on the edge of each open area or on the sidewall of the entire support frame to cover the open area. In use, the multiple protection units are axially deployed graded along the target location, with the flexible support frame of each protection unit fully conforming to the inner wall of the blood vessel, and the soft, elastic filter membrane intercepting emboli in the blood flow. This addresses at least the technical problems of existing embolization protection devices, such as poor flexibility due to the high coverage of the rigid support structure, difficulty in adapting to complex vascular morphologies, and poor fit with the vascular wall, leading to embolism escape.

The utility model discloses a rainfall sensor calibrator capable of metering accurately, which comprises a water container, a weighing module arranged at the bottom of the water container, a base arranged at the bottom of the weighing module, a peristaltic pump arranged on the base, a water delivery pipe connected between the peristaltic pump and the water container, an output pipe connected with the output end of the peristaltic pump, and an output pipe connected with the output end of the peristaltic pump. A sealing mechanism is arranged at one end of the output pipe away from the peristaltic pump. By arranging the sealing mechanism, quantitative water is injected into the water container firstly, the peristaltic pump is started to feed the water into the hollow frame, the closed disc is jacked open by water pressure to discharge residual liquid in the water conveying pipe, water pumping is stopped to ensure no liquid leakage, and first weighing is completed; water pumping is started again, the liquid jacks open the closed disc to flow to the rainfall sensor, the closed disc is reset and sealed after water pumping is finished, the main control board calculates the accurate output quantity through the difference value of two times of weighing, the influence of residual liquid is effectively avoided, and the calibration precision and reliability are improved.

The utility model discloses a kind of computer room heat recovery devices, belong to computer room heat recovery device technical field, its technical scheme main points include recovery bucket, the inner wall of the recovery bucket is provided with heat recovery mechanism, the surface of the recovery bucket is provided with heat preservation cover, the top of the recovery bucket is provided with water inlet pipe, the bottom of the recovery bucket is provided with water outlet pipe, the top of the recovery bucket is hinged with temperature detection component, the left side of the heat recovery mechanism is fixedly connected with filter box, the inner wall of the filter box is provided with air guide structure, solve the computer room heat recovery device of existing when using, mostly difficult to quickly absorb hot air heat, lead to computer room cooling effect is lower, and energy waste is too much, and dust impurities in hot air is easy to block hot air transmission channel, lead to hot air to export slowly, cause computer room heat accumulation, threaten equipment stable operation, improve maintenance cost and downtime risk problem.
