This invention discloses an air purification device for forest health and wellness, comprising a mounting frame, within which a main body capable of moving forward is located. The main body is used for air purification. A control panel is located at the front end of the main body, and several air outlets are located around the front perimeter. An air inlet is located at the rear end of the main body. A high-efficiency filter is detachably installed on the inner side of the air inlet, and a pre-filter is detachably installed on the outer side of the air inlet. A cleaning component is installed on the pre-filter. The main body contains a fan, a dehumidification mechanism, and a humidification mechanism. The cleaning component, fan, dehumidification mechanism, and humidification mechanism are all electrically connected to the control panel. This invention connects the rear air inlet of the main body to the outside environment by embedding the support frame into a wall. The fan, pre-filter, and high-efficiency filter then filter and purify the air from the forest before drawing it into the room, ensuring the health and wellness effect. Moving the main body forward facilitates subsequent maintenance of the rear end of the main body from inside the room, ensuring the normal operation of the device.

This utility model discloses a vehicle-mounted electric well-working rig winch motor transmission device, belonging to the technical field of well-working rig winch motors. It solves the problem of large space occupation in the transmission system of existing vehicle-mounted well-working rig winch motors. It includes a hollow shaft motor, with a drum-shaped gear coupling installed inside the hollow shaft. One end of the drum-shaped gear coupling is fixedly connected to one end of the hollow shaft, and the other end is fixedly connected to the winch input shaft. A connecting key for insertion into the winch input shaft is provided on the connection end of the drum-shaped gear coupling and the winch input shaft. This utility model, by incorporating a drum-shaped gear coupling within the hollow shaft motor, eliminates intermediate structures such as a gearbox and tensioning device, significantly reducing the size of the transmission device, meeting the space constraints of the vehicle-mounted platform, and eliminating redundant components such as the protective cover, thus reducing the failure rate and maintenance costs.
