The limiting sleeve covers the outside of the force applying mechanism.

Abstract: A nasal irrigator includes a nasal irrigator body, a nasal irrigator handle, a clean water tank, and a dirty water tank. The clean water tank and the dirty water tank are both arranged on a side of the nasal irrigator body, and a water inlet pump communicated with the clean water tank and a dirty water pump communicated with the dirty water tank are provided inside the nasal irrigator body. The nasal irrigator body is provided with an insertion hole configured to fix the nasal irrigator handle, and the nasal irrigator handle is capable of being inserted into the insertion hole or taken out of the insertion hole. A water inlet soft rubber nozzle and a water return soft rubber nozzle are mounted on the nasal irrigator handle.

Abstract: A fan assembly includes two fan apparatuses and at least one connector. Each of the two fan apparatuses includes a frame, a fan blade and at least one first terminal. The frame has at least one first engagement recess. The fan blade is rotatably disposed on the frame. The at least one first terminal is located in the at least one first engagement recess. The at least one connector includes a first assembly block and two second terminals. The first assembly block includes two first engaging portions connected to each other. The two second terminals are respectively mounted on the two first engaging portions. The two first engaging portions of the first assembly block are respectively engaged with the at least two first engagement recesses of the two frames, and the two second terminals are respectively plugged and electrically connected to the at least two first terminals.

Abstract: A tight-fit riveting structure for a clustered radiation fin set and a heat pipe and a riveting method include a radiation fin set formed by locking a plurality of radiation fins together and at least one heat pipe. The radiation fin set has an accommodation slot for accommodating the heat pipe. The heat pipe is positioned in the accommodation slot for a tight fit by subjecting two sides of the accommodation slot of the radiation fin set to a riveting operation. First riveting and deforming portions defined on two sides of a communication mouth of the accommodation slot are riveted towards a surface of the heat pipe, which causes the deformation of the first riveting and deforming portions whereby the heat pipe is clamped in a tight fit manner.
