The utility model discloses a battery changing structure for an aircraft, which belongs to the technical field of new energy and energy conservation and is characterized by comprising a module battery, quick clamping mechanisms are movably connected to two sides of the module battery, and splicing mechanisms are movably connected to the front side and the rear side of the module battery. By means of the hollow inner cavity, the sectional clamping sliding block and the linkage structure, the supporting block can be triggered to automatically support the inner wall of the battery bin tightly by extruding the protruding block when the module battery is in sliding connection, the effects of being fast and stable to install, not occupying external space and being convenient to disassemble are achieved, the problem that it is troublesome to replace the lithium battery module outdoors is solved, no complex tool is needed, and the cost is reduced. Through the optimized splicing structure of the module battery shell, pre-splicing through insertion connection and elastic clamping connection is achieved, on the premise that the size and the length-width ratio of a battery are not affected, a battery bin of the aircraft does not need to be adjusted, and pre-splicing can be conducted before the aircraft reaches a supply point.

The utility model discloses a button cell mounting structure of disposable dental handpiece, including handle, machine head, handle both ends are operating end and connecting end respectively, operating end is equipped with illuminating lamp, handle is inlayed and is equipped with battery compartment, battery compartment is equipped with the lid, the outer surface of lid and the outer peripheral wall of handle are smooth transition, battery compartment is equipped with button cell, battery compartment is equipped with the mouth, the mouth is long strip, the conductive sheet of battery compartment is electrically connected with illuminating lamp, machine head is connected with operating end. Button cell meets the manufacturing cost of disposable dental handpiece, compared with traditional button cell mounting mode, the button cell of the application is inlaid in handle, does not affect the original size of handle, is favorable to the operation of doctor. Secondly, the structure still does not affect the overall shape and appearance of handle, is favorable to improving the aesthetic property.

The invention provides a ship body protection device for a ship, and relates to the technical field of ship body protection, the ship body protection device comprises a ship bottom, an anti-collision column is fixed on the surface of the bottommost part of the ship bottom, an anti-collision assembly is arranged in the anti-collision column, the anti-collision assembly comprises a storage frame, and a rolling shaft is rotatably mounted in the storage frame through a bearing and a torsion spring; a plurality of air bags are wound on the winding shaft, every two adjacent air bags are fixedly connected, the air bag at the bottommost part of the storage frame is fixed to the interior of the anti-collision column, and a driving assembly is arranged at the top of the ship bottom slope. The anti-collision assembly can achieve the anti-collision effect on the two sides of the ship, the anti-collision assembly can be opened when used and closed when not used, normal traveling and the size of the ship cannot be affected, the anti-collision assembly can clean the slope of the ship when unfolded, and manual cleaning of algae and shells is replaced.

The utility model relates to ventilation therapy technical field discloses a kind of heating assembly, humidifier and ventilation therapy equipment.The heating assembly is used to set in the shell wall for limiting liquid storage cavity of humidifier, the heating assembly includes wire circuit and electrode connected with each other, electrode is used to connect with external power supply, to realize the energization of wire circuit.Through the above scheme, a kind of heating assembly capable of being set in the shell wall for limiting liquid storage cavity of humidifier is provided, heating assembly can directly heat the liquid in liquid storage cavity, heat utilization rate is high, and it does not affect the internal volume and appearance size of humidifier;In addition, heating assembly is heated by adopting wire circuit, not only conducive to the control of heating, but also conducive to integrating various detection components, to synchronously detect the water temperature, water level, air pressure etc. in humidifier.

The utility model discloses an EC fan filter element vacuum solid-liquid separation oil mist purification device which comprises an EC fan body, a first annular piece is arranged in the EC fan body, a connecting piece is arranged on the outer side of the first annular piece and connected with the inner wall of the rear side of the EC fan body, a first filter layer is arranged on the front side of the first annular piece, and a second filter layer is arranged on the rear side of the first annular piece. The utility model relates to the technical field of oil mist purification, and has the beneficial effects that the first filter layer, the second filter layer and the third filter layer are respectively added in the EC fan main body, so that the size of the EC fan main body is not influenced, the size of the EC fan main body is reduced, and the oil mist purification efficiency is improved. According to the EC fan, efficient solid-liquid separation and oil mist purification operation can be conducted on air entering the EC fan body, separated oil mist can be collected through the collecting hopper, the overall size is small, and use is flexible.
