  In order to make the technical features, objects, and technical effects of the present invention clear, specific embodiments of the present invention will be described in detail below with reference to the drawings.

  As shown in FIGS. 1 to 7, the elevating fan according to the present invention includes a pedestal 1 for supporting a main body portion of the fan and a telescopic tube 2 positioned above the pedestal 1. The telescopic tube 2 is movably connected to the sleeve 11 so as to be inserted into the sleeve 11 of the base 1. A fan cover and a fan blade are attached to the top end of the telescopic tube 2. The elevating fan according to the present invention further includes a rotary motor 3 and a rope 4 mounted on the base 1. One end of the rope 4 is connected to the output end 30 of the rotary motor 3, and the other end 50 of the rope 4 is connected to the telescopic tube 2. The rotary motor 3 controls the slackness of the rope 4 by rotating clockwise (forward rotation) or counterclockwise (reverse rotation), thereby realizing the lifting and lowering of the telescopic tube 2. An elastic return member is further provided between the telescopic tube 2 and the base 1. One end of the elastic return member acts on the telescopic tube 2, and the other end 50 of the elastic return member acts on the base 1. The telescopic tube 2 is raised by the return force of the elastic return member.

  When the rotary motor 3 rotates clockwise, the rope 4 is wound around the output end 30 and contracted, and then the telescopic tube 2 is pulled down to lower the elevating fan. When the elevating fan descends, the elastic return member is deformed and accumulates elastic energy. When the rotary motor 3 rotates counterclockwise, the rope 4 is released and the elastic return member loses the limiting force from the rope 4 and returns to reset. This return force pushes up the telescopic tube 2 to the spring and realizes the raising of the elevating fan.

  The elastic return member preferably employs an elastic spring 5. The main body 52 of the elastic return member (the one end of the elastic spring 5 is included in the main body 52) is mounted in the telescopic tube 2. The other end 50 passes through the opening 20 formed in the side wall of the telescopic tube 2 and is fixed to the sleeve 11 of the base 1. When the telescopic tube 2 is pulled down by the rope 4, the elastic spring 5 expands and deforms, and the elastic energy is stored. When the acting force from the rope 4 is canceled, the elastic spring 5 rebounds and pushes up and raises the telescopic tube 2.

  In general, a hook 13 is provided on the side wall of the sleeve 11 of the base 1. On the outside of the hook 13, a drop-off prevention baffle 130 for preventing the suspension structure from being detached is provided so as to extend upward. A suspension port 51 corresponding to the hook 13 is provided at the other end 50 of the elastic return member. In order to ensure stability when the telescopic tube 2 moves up and down, a longitudinal chute 21 and a slide block 12 that cooperate with each other are provided on the outer wall of the telescopic tube 2 and the inner wall of the sleeve 11 of the base 1, respectively. The slide block 12 moves along the chute 21 and serves as a direction guide. Preferably, there are two chutes 21 and two slide blocks 12 respectively.

  The elastic return member preferably employs a compression spring. The pedestal 1 is provided with a carrier plate corresponding to the bottom and top and bottom of the telescopic tube 2. The compression spring is attached between the bottom of the telescopic tube 2 and the carrier plate. When the telescopic tube 2 is lowered, the compression spring is pressed by the telescopic tube 2. When the pulling force of the rope 4 on the telescopic tube 2 is gradually cancelled, the compression spring returns and presses the telescopic tube 2 upward against the spring.

  The rotary motor 3 is generally fixed to the bottom plate 10 of the base 1. A reel for winding a wire is attached to the output end 30 of the rotary motor 3. One end of the rope 4 is provided on the reel, and the other end 50 of the rope 4 passes through the inside of the sleeve 11 and is fixed to the bottom of the telescopic tube 2. A remote control circuit is further provided on the motherboard of the rotary motor 3. Forward rotation and reverse rotation of the rotary motor 3 can be realized by receiving an external control signal by the remote control circuit. Thereby, the user can remotely operate the elevating fan of the present invention. Since the operating principle of the remote control circuit is a well-known technique, a detailed description thereof is omitted here.

  The improved elevating fan according to the present invention controls the raising / lowering of the fan via the rotary motor 3, whereby the user holds the fan sleeve 11 with one hand and moves the telescopic tube 2 up and down with one hand. This avoids the difficult situation of adjusting the height of the fan. Moreover, since the rotary motor 3 can be remotely controlled using a conventional remote control circuit, the elevation adjustment for the fan is further convenient and simple.

The present invention has been described above with reference to preferred specific examples. However, the present invention is not limited to the above-described embodiments, and various modifications or replacements are possible without departing from the scope of the present invention. Needless to say. It is obvious that various modifications based on this change or replacement are also included in the protection scope of the present invention.
