Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figures, the fan device with the shock absorption function of the utility model comprises a base 1, a shell 3 positioned above the base 1, a fan body 4 positioned in the shell 3, a protective cover 2 positioned above the shell 3 and fixedly connected with the base 1 at the bottom, a shock absorption device arranged between the shell 3 and the base 1 and a buffer device arranged between the shell 3 and the protective cover 2, a connecting part 8 fixedly connected with the shell 3 is arranged below the shell 3, the shock absorption device comprises a chute 5 arranged on the base 1, a slide block 6 symmetrically arranged in the chute 5 and sliding along the chute 5, a connecting lug 7 arranged at one end of the slide block 6 close to each other, and a first spring 10 symmetrically arranged at one end of the slide block 6 far away from the connecting lug 7 and fixedly connected with the chute 5 and the slide block 6 at the two ends respectively, and the symmetry set up in engaging lug 7 with between connecting portion 8 and its one end with engaging lug 7 rotates to be connected, its other end with connecting portion 8 rotates the connecting rod 9 of connecting, buffer including set up in through-hole 15, one end on 2 tops of protection casing with 3 fixed connection of casing, its other end pass through-hole 15 and the slide bar 13 of stretching out, set up in protection casing 2 with between the casing 1 and the cover establish the outside second spring 14 of slide bar 13, and set up in protection casing 2 is kept away from the stopper 17 of 3 one end of casing stopper 17 with set up the cover between the protection casing 2 and establish the outside third spring 16 of slide bar 13. Be convenient for slide bar 13 with under the effect of second spring 14, slow down fan body 4 is receiving vibrations and the orientation deviates from moving speed and displacement distance when base 1 direction removes, and first spring 10 with under the effect of third spring 16, slow down the fan is at the orientation moving speed when base 1 direction removes, make casing 3 slowly descends to on the base 1, prevent that the spare part of fan body 4 takes place to become flexible or damage.
Preferably, said damping means are arranged in groups side by side between said housing 3 and said protection casing 2. The fan body 4 is convenient to be stressed uniformly when the shell 3 moves between the protective cover 2, and meanwhile, the buffering effect is improved.
Preferably, soundproof cotton 11 circumferentially fixed to the inner wall of the casing 3 is provided between the casing 3 and the blower body 4. The sound generated by the operation of the fan body 4 is absorbed conveniently under the action of the soundproof cotton 11, and the noise of the fan equipment is reduced.
Preferably, a plurality of sets of mounting holes 12 are provided on the base 1. The blower body 4 is convenient to be installed at a corresponding position through a plurality of groups of installation holes 12 on the base 1.
When the fan is in operation, the fan body 4 is installed at a corresponding position through a plurality of groups of installation holes 12 arranged on the base 1, when the fan body 4 operates, a motor in the fan body 4 rotates to cause vibration of the fan body 4, so that the shell 3 reciprocates between the base 1 and the protective cover 2, and when the shell 3 moves in a direction departing from the base 1, the sliding rod 13 can be driven to overcome the elastic force of the second spring 14 to move in a direction departing from the base 1, so that the connecting rod 9 is driven to rotate along the connecting lug 7 and the connecting portion 8, the sliding block 6 is driven to move in a direction approaching to each other, and the moving speed and the moving distance of the shell 3 are reduced; when the shell 3 moves towards the direction of the base 1, the shell 3 drives the sliding rod 13 to move towards the direction of the base 1, so that the connecting rod 9 rotates along the connecting lug 7 and the connecting part 8, the sliding block 6 overcomes the elastic force of the first spring 10 and moves towards the direction of mutual deviation, and the shell 3 slowly falls onto the base 1.
Owing to set up the casing with damping device between the base is in with the setting the casing with buffer between the protection casing the slide bar with under the effect of second spring, slow down fan body is receiving vibrations and the court deviates from moving speed and displacement when the base direction removes, and first spring with under the effect of third spring, slow down the fan is in court moving speed when the base direction removes makes fan body slowly descends to on the base, when fan equipment is receiving vibrations, prevents fan body's spare part takes place not hard up and damages, prolongs fan equipment's life, reduces fan body's motor simultaneously and rotates and drive fan equipment's frequency of vibration to noise reduction.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
